The Exchange Notes and the Old Notes are collectively referred to herein as the "Notes." Doe Run will accept for exchange any and all Old Notes that are validly tendered and not withdrawn on or prior to 5:00 p.m., New York City time, on , 1998, unless the Exchange Offer is extended (the "Expiration Date"). Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date. The Exchange Notes will be issued and delivered promptly after the Expiration Date. The Exchange Offer is not conditioned upon any minimum principal amount of Old Notes being tendered for exchange. See "The Exchange Offer." Old Notes may be tendered only in integral multiples of $1,000. The Company has agreed to pay the expenses of the Exchange Offer. The Exchange Notes will be obligations of Doe Run evidencing the same debt as the Old Notes and will be entitled to the benefits of the same indenture, dated as of March 12, 1998 (the "Indenture"), by and among Doe Run, as issuer, and certain of Doe Run's existing subsidiaries, Fabricated Products, Inc., a Delaware corporation ("FPI"), Doe Run Cayman Ltd., a Cayman Islands company ("Doe Run Cayman"), Doe Run Mining S.R. Ltda., a Peruvian company ("Doe Run Mining"), and Doe Run Peru S.R. Ltda., a Peruvian company (together with its predecessors, "Doe Run Peru"), as guarantors (the "Guarantors"), and State Street Bank and Trust Company, as trustee (the "Trustee"). The form and terms of the Exchange Notes are substantially the same as the form and terms of the Old Notes except that the Exchange Notes have been registered under the Securities Act. See "The Exchange Offer." The Exchange Notes will bear interest from March 12, 1998. Holders of Old Notes whose Old Notes are accepted for exchange will be deemed to have waived the right to receive any payment in respect of interest on the Old Notes accrued up (COVER CONTINUES ON FOLLOWING PAGE) ------------------------ SEE "RISK FACTORS" BEGINNING ON PAGE 22 FOR A DISCUSSION OF CERTAIN FACTORS THAT SHOULD BE CONSIDERED IN EVALUATING AN INVESTMENT IN THE EXCHANGE NOTES. --------------------- THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE. THE DATE OF THIS PROSPECTUS IS , 1998. 2 (CONTINUATION OF COVER) until the date of the issuance of the Exchange Notes. Such waiver will not result in the loss of interest income to such holders because the Exchange Notes will bear interest from the issue date of the Old Notes. The Fixed Rate Exchange Notes will mature on March 15, 2005. The Floating Rate Exchange Notes will mature on March 15, 2003. Interest on the Exchange Notes will be payable semi-annually in arrears on March 15 and September 15 of each year, commencing on September 15, 1998, at the rate of 11 1/4% per annum in the case of the Fixed Rate Exchange Notes, and at a rate per annum equal to LIBOR (as defined) plus 6.29% (currently, 12.00875%) in the case of the Floating Rate Exchange Notes. Interest on the Floating Rate Exchange Notes will be reset semi-annually. The Fixed Rate Exchange Notes will be redeemable, in whole or in part, at the option of Doe Run, on or after March 15, 2002, and the Floating Rate Exchange Notes will be redeemable, in whole or in part, at the option of Doe Run, at any time, in each case at the redemption prices set forth herein, plus accrued interest to the date of redemption. In addition, at any time on or prior to March 15, 2001, Doe Run may redeem up to 35% of the aggregate principal amount of the Fixed Rate Exchange Notes with the net cash proceeds of one or more Equity Offerings (as defined), at the redemption price set forth herein, plus accrued interest to the date of redemption, PROVIDED that at least 65% of the aggregate principal amount of the Fixed Rate Exchange Notes remains outstanding immediately following such redemption. Upon a Change of Control (as defined), each holder of Exchange Notes will have the right to require Doe Run to repurchase such holder's Exchange Notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the repurchase date. In addition, Doe Run will be obligated to offer to repurchase the Exchange Notes at 100% of the principal amount thereof plus accrued and unpaid interest to the date of repurchase in the event of certain Asset Sales (as defined). See "Description of the Notes." The Exchange Notes will be unconditionally guaranteed (the "Guarantees") by the Guarantors. The Exchange Notes and the Guarantees will be general unsecured obligations of Doe Run and the Guarantors, respectively, and will rank senior in right of payment to all existing and future subordinated indebtedness of Doe Run and the Guarantors, respectively, and PARI PASSU in right of payment with other senior indebtedness of Doe Run and the Guarantors, respectively, subject, in the case of the Guarantees of Doe Run Mining and Doe Run Peru, to statutorily preferred exceptions and statutorily mandated priorities based on the date of issuance with respect to payment of obligations under applicable Peruvian law. However, Doe Run's indebtedness under its new $100 million revolving credit facility (the "New Doe Run Revolving Credit Facility") is secured by substantially all of the current assets of Doe Run. In addition, Doe Run Peru expects to enter into a new $40.0 million revolving credit facility (the "New Doe Run Peru Revolving Credit Facility"), which will be secured by substantially all of the current assets of Doe Run Peru. Holders of such secured indebtedness, and any other secured indebtedness of Doe Run and the Guarantors, will have claims that effectively rank prior to those of holders of Exchange Notes with respect to the assets securing such indebtedness. In addition, the Guarantee of Doe Run Peru will be contractually subordinated to the indebtedness of Doe Run Peru under the New Doe Run Peru Revolving Credit Facility. As of January 31, 1998, on a pro forma consolidated basis, the Company would have had approximately $380.9 million of indebtedness outstanding (exclusive of anticipated aggregate commitments of $140 million under the New Doe Run Revolving Credit Facility and the New Doe Run Peru Revolving Credit Facility (collectively, the "New Revolving Credit Facilities"). Each broker-dealer that receives Exchange Notes for its own account in exchange for Old Notes, where such Old Notes were acquired by such broker-dealer as a result of market-making or other trading activities, must acknowledge that it will deliver a Prospectus in connection with any resale of such Exchange Notes. The Letter of Transmittal states that, by so acknowledging and by delivering a Prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Old Notes where such Old Notes were acquired by such broker-dealer as a result of market-making or other trading activities. Doe Run has agreed that for a period of 180 days after consummation of the Exchange Offer, it will make this Prospectus, as it may be amended or supplemented from time to time, available to any broker-dealer for use in connection with any such resale. See "Plan of Distribution." There has been no public market for the Old Notes. If a market for the Exchange Notes should develop, the Exchange Notes could trade at a discount from their principal amount. Doe Run does not intend to list the Exchange Notes on a national securities exchange or quotation system. There can be no assurance that an active public market for the Exchange Notes will develop. 3 AVAILABLE INFORMATION Doe Run and the Guarantors have filed with the Securities and Exchange Commission (the "Commission") a Registration Statement on Form S-4 (together with all amendments, exhibits, schedules and supplements thereto, the "Registration Statement") under the Securities Act with respect to the Exchange Notes offered hereby.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS This Prospectus includes "forward-looking statements." All statements other than statements of historical facts included in this Prospectus, including without limitation, certain statements under the captions "Prospectus Summary," "Management's Discussion and Analysis of Financial Condition and Results Of Operations," "Industry" and "Business" and located elsewhere herein regarding the financial position and business strategy of the Company, may constitute forward-looking statements. In addition, forward-looking statements generally can be identified by the use of forward-looking terminology such as "may," "will," "expect," "intend," "estimate," "anticipate," "believe" or "continue" or the negatives thereof or variations thereon or similar terminology. Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, it can give no assurance that such expectations will prove to have been correct. Important factors that could cause actual results to differ materially from Doe Run's expectations ("Cautionary Statements") are disclosed in this Prospectus, including, without limitation, in conjunction with the forward-looking statements included in this Prospectus and under "Risk Factors." All subsequent written and oral forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by the Cautionary Statements. These forward-looking statements speak only as of the date of this Prospectus. The Company expressly disclaims any obligation or undertaking to disseminate any updates or revisions to any forward-looking statement contained herein to reflect any change in their expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based. ENFORCEABILITY OF CIVIL LIABILITIES Each of Doe Run Peru and Doe Run Mining is organized under the laws of the Peru. Doe Run Cayman is incorporated under the laws of the Cayman Islands. Certain experts named herein with respect 3 to Doe Run Peru and Doe Run Mining reside outside of the United States, and substantially all of the assets of such persons and of Doe Run Peru and Doe Run Mining are located outside of the United States. As a result, it may not be possible for investors to effect service of process upon such persons or Doe Run Peru, Doe Run Cayman and Doe Run Mining or to enforce against them in the United States, or to realize judgments of courts located outside of the Cayman Islands or Peru predicated upon civil liability provisions of the federal or state securities laws of the United States. The Company believes that there are potential defenses to the enforceability, in original actions in Cayman Islands or Peruvian courts, of liabilities predicated solely on the U.S. federal and state securities laws and as to the enforceability in Cayman Islands or Peruvian courts of judgments of U.S. courts obtained in actions predicated upon the civil liability provisions of the U.S. federal and state securities laws. PRESENTATION OF CERTAIN FINANCIAL INFORMATION Unless otherwise specified or the context otherwise requires, references to "$," "US$," "U.S.$," "dollars," and "U.S. dollars" are to United States dollars and references to "S/.," "nuevo sol" or "nuevos soles" are to Peruvian nuevos soles. Each nuevo sol is divisible into 100 centimos. See "Exchange Rates." The financial statements of Empresa Minera del Centro Peru S.A.--Centromin Peru S.A., La Oroya Division included herein are prepared in U.S. dollars and in accordance with generally accepted accounting principles in the United States ("U.S. GAAP"). Doe Run Peru and Doe Run Mining maintain their financial records in nuevos soles, prepare financial information in accordance with generally accepted accounting principles in Peru ("Peruvian GAAP") and report such information to the Peruvian government on this basis for purposes of calculating its Peruvian tax liability. These amounts are calculated on the basis of Peruvian GAAP and, therefore, cannot be directly derived from the consolidated financial statements appearing in this Prospectus, which are prepared in accordance with U.S. GAAP. Peruvian GAAP requires the inclusion in the financial statements of Doe Run Peru and Doe Run Mining the Resultado de Exposicion a la Inflacion which seeks to account for the effects of inflation by adjusting the value of non-monetary assets and liabilities and equity by a factor corresponding to Peruvian wholesale price inflation rates during the period covered by the financial statements. Monetary assets and liabilities are not adjusted. EXCHANGE RATES During the last two decades, the Peruvian government has imposed various exchange controls ranging from strict control over exchange rates to market determination of rates. Prior to early 1991, the Peruvian foreign exchange market consisted of multiple exchange rates. Since early 1991, there have been no exchange controls in Peru and all foreign exchange transactions are based on free market exchange rates. Current Peruvian regulations on foreign investment allow foreign investors to receive and repatriate all earnings and investments in Peru. Investors are allowed to purchase foreign currency at free market exchange rates through any member of the Peruvian banking system and transfer such foreign currency outside Peru without restriction. A portion of Doe Run Peru's operating costs are denominated in nuevos soles. Because substantially all the revenues of Doe Run Peru are denominated in U.S. dollars, when inflation in Peru is not offset by a corresponding devaluation of the nuevo sol versus the U.S. dollar, the financial position, results of operations and cash flows of Doe Run Peru will be adversely affected. See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Liquidity and Capital Resources--Inflation and Seasonality." Doe Run Peru has not in the past entered into any foreign exchange hedging arrangements. 4 The following table sets forth the high and low month-end, average month-end and end of period noon buying rates in New York City for customs purposes as set forth in INTERNATIONAL FINANCIAL STATISTICS published by the International Monetary Fund of nuevo soles for U.S. dollars for the periods indicated:

The noon buying rate in New York City for customs purposes as set forth in INTERNATIONAL FINANCIAL STATISTICS published by the International Monetary Fund as of October 31, 1997 and January 31, 1998 was S/.2.720 and S/.2.770, respectively, per $1.00. 5 PROSPECTUS SUMMARY THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED INFORMATION, FINANCIAL STATEMENTS, INCLUDING THE NOTES THERETO, AND OTHER DATA APPEARING ELSEWHERE IN THIS PROSPECTUS. UNLESS THE CONTEXT OTHERWISE REQUIRES, AS USED HEREIN: "OUNCE" MEANS A TROY OUNCE (1.09 OUNCES); "TON" MEANS A SHORT TON (2,000 POUNDS); AND "WESTERN WORLD" MEANS THE ENTIRE WORLD EXCLUDING EASTERN EUROPE, THE FORMER SOVIET UNION AND CHINA. THE COMPANY'S FISCAL YEAR ENDS OCTOBER 31, AND THUS, FOR EXAMPLE, "FISCAL 1997" REFERS TO THE FISCAL YEAR ENDED OCTOBER 31, 1997. PRIOR TO THE ACQUISITION (AS DEFINED), DOE RUN PERU'S FISCAL YEAR ENDED DECEMBER 31. THE COMPANY MAINTAINS ITS PRINCIPAL EXECUTIVE OFFICES AT 1801 PARK 270 DRIVE, ST. LOUIS, MISSOURI 63146, AND ITS TELEPHONE NUMBER IS (314) 453-7100. THE COMPANY Doe Run is the largest fully-integrated lead producer in North America and the second largest primary lead producer in the western world. Through its subsidiary Doe Run Peru, Doe Run operates one of the largest polymetallic processing companies in the world offering an extensive product mix of non- ferrous and precious metals, including copper, silver, zinc, lead and gold. The combined capabilities of Doe Run and Doe Run Peru represent the largest primary lead producer in the western world. On October 23, 1997, Doe Run Peru acquired (the "Acquisition") Empresa Metalurgica La Oroya S.A. ("Metaloroya") from Empresa Minera del Centro del Peru S.A., a Peruvian government-owned conglomerate ("Centromin"), as part of the ongoing privatization program sponsored by the government of the Republic of Peru ("Peru"). On December 30, 1997, Metaloroya was merged into Doe Run Peru (the "Merger"). The Company had pro forma net sales and EBITDA (as defined) of $709.8 million and $74.5 million, respectively, for the twelve months ended October 31, 1997 and net sales and EBITDA of $169.1 million and $17.7 million, respectively, for the three months ended January 31, 1998. DOE RUN Doe Run's integrated operations permit Doe Run to participate in and manage the entire lead life cycle, including the mining of lead ore, the production of refined lead metal, the fabrication of value-added lead products and the secondary recycling of spent lead-acid batteries and other lead-bearing materials. Doe Run believes its reputation for excellent service, product quality and timely delivery permits it to consistently realize premiums for its products, resulting in sales prices above the market price for lead quoted on the London Metal Exchange (the "LME"). In fiscal 1997, Doe Run shipped approximately 350,000 tons of refined lead metal and lead alloy products, including recycled lead, representing approximately 19% of North American consumption and 6% of western world consumption. Doe Run had net sales and EBITDA of $277.9 million and $31.9 million, respectively, for fiscal 1997, excluding the results of operations of Doe Run Peru for the eight-day period from October 23, 1997 (the date of consummation of the Acquisition) through October 31, 1997 and net sales and EBITDA of $59.8 million and $1.7 million, respectively, for the three months ended January 31, 1998. Refined lead product sales accounted for approximately 67% and 68% of Doe Run's total net sales, or $185.1 million and $41.0 million, respectively, in fiscal 1997 and for the three months ended January 31, 1998, respectively. The balance of Doe Run's net sales resulted from (i) tolling services provided to major U.S. lead-acid battery manufacturers, (ii) lead production by-products, including zinc and copper concentrates, and (iii) value-added fabricated lead products, such as lead sheet and bricks. These net sales from tolling services, by-products and fabricated products provide sources of revenue largely independent of lead prices. Western world lead consumption in 1997 was estimated at 5.8 million tons which represents a total market of approximately $3.2 billion. Approximately 4.2 million tons, or 72%, of this lead was used in the production of lead-acid batteries, approximately 75% of which was for starting-lighting-ignition ("SLI") 6 batteries. Approximately 83% of SLI battery sales are in the automotive replacement market, a market with stable demand characteristics, which is dependent upon the number of automobiles in service and battery life. Doe Run's customers include six of the seven largest lead-acid battery manufacturers in the world. The lead-acid battery remains the most cost competitive battery technology for SLI batteries, which management believes will not change in the foreseeable future. Other uses for refined lead include computer and television screens, ammunition, stationary batteries used as backup power sources and rolled and extruded lead products used in radiation shielding and roofing materials. The market for refined lead continues to grow primarily as a result of increasing demand for lead-acid batteries used for automobiles and other vehicles as a result of worldwide economic growth. As a result, western world lead consumption grew at a compound annual growth rate ("CAGR") of 2.0% between 1987 and 1997, growing 0.75% from 1996 to 1997. Doe Run believes that this growth rate will accelerate in the future as batteries become an even larger portion of the lead market, particularly in light of expected economic growth leading to increased vehicle population in developing economies. Approximately 45% of annual worldwide lead consumption is supplied from newly mined or "primary" ore, and the balance is supplied from secondary sources, principally the recycling of spent lead-acid batteries and other lead-bearing materials. Since 1990, primarily due to heightened environmental awareness, secondary lead capacity has increased, whereas primary lead capacity has remained relatively constant. Management believes that secondary sources of lead will continue to account for an increasing share of the total worldwide lead market. The average LME price for refined lead was $.29 per pound in fiscal 1997. As of March 31, 1998, the LME price for lead was $.26 per pound, which was below the ten-year average price of $.28 per pound. Management believes that lead prices will remain relatively stable or will modestly increase for the remainder of fiscal 1998 and over the long term will reflect the historical industry average. As a result of the recent lead price decreases, the Company expects that it will incur an operating loss in its U.S. operations that will adversely affect its EBITDA in fiscal 1998. Doe Run conducts its mining operations along approximately 40 miles of the Viburnum Trend in Southeastern Missouri, one of the world's most productive lead deposits. Doe Run operates six production shafts, four processing mills, one primary smelter and one secondary smelter. During fiscal 1997, Doe Run mined in excess of 5.0 million tons of ore containing average grades of 5.17% lead, 1.02% zinc and 0.27% copper. At the end of fiscal 1997, Doe Run's proven and probable reserves consisted of approximately 70 million tons, containing approximately 3.8 million tons of recoverable lead or approximately fourteen years of production at current mining rates. Doe Run's primary smelter in Herculaneum, Missouri is the largest in North America and the second largest in the world, with an annual production capacity of approximately 250,000 tons of refined lead. Since entering the recycling business in 1992, Doe Run has become a leading producer of secondary lead at its Buick recycling facility and secondary smelter located in Boss, Missouri. At this facility, Doe Run is reclaiming at a rate of approximately 105,000 tons of refined lead per year, approximately 60% of which is derived from tolling arrangements with major U.S. battery manufacturers. DOE RUN PERU Doe Run Peru's unique combination of base metal smelters, refineries and by-product circuits enable Doe Run Peru to process complex polymetallic concentrates and to recover base metals and by-products at international quality standards. Doe Run Peru's location in central Peru, approximately 110 miles from Lima, allows Doe Run Peru to source concentrates advantageously from mines located throughout the central Andes mountains, particularly in Peru. Moreover, Doe Run Peru's proximity to Lima's Callao port provides it ready access to major world markets for its products. For the twelve months ended October 31, 1997 and the three months ended January 31, 1998, Doe Run Peru shipped approximately 70,000 tons and 18,000 tons, respectively, of refined copper, 107,000 tons 7 and 27,000 tons, respectively, of refined lead, 71,000 tons and 18,000 tons, respectively, of refined zinc, 20.5 million ounces and 6.5 million ounces, respectively, of refined silver and 42,000 ounces and 13,000 ounces, respectively, of gold bullion. In addition, Doe Run Peru shipped various by-products including bismuth, indium, tellurium, antimony, cadmium and copper blister. Doe Run Peru had net sales and Adjusted EBITDA (as defined) of $431.9 million and $50.7 million, respectively, for the twelve months ended October 31, 1997, including the period from October 23, 1997 through October 31, 1997, and net sales and EBITDA (excluding intercompany transactions) of $109.2 million and $16.0 million, respectively, for the three months ended January 31, 1998. Of Doe Run Peru's net sales, refined copper, silver, zinc, lead and gold accounted for 35%, 23%, 19%, 15% and 3%, respectively, for the twelve months ended October 31, 1997, and 26%, 32%, 18%, 13% and 3%, respectively, for the three months ended January 31, 1998, with the balance of net sales derived from sales of various by-products. For the twelve months ended December 31, 1997, Doe Run Peru was Peru's second largest exporter, exporting approximately 80% of its total shipments to North America, Europe and Asia, as well as other Latin American countries. Doe Run Peru's customers include end-users of base metals and metal by-products, as well as international metal trading companies. Doe Run Peru's operations consist of smelting and refining complex concentrates that it purchases from unaffiliated mining operations. Doe Run Peru typically purchases concentrate feedstock pursuant to annual contracts at a price based on a percentage of the payable base metal and precious metal content of the concentrates. The price is reduced by processing fees or treatment charges to refine the concentrates, as well as by penalties charged to remove impurities within the concentrates, such as arsenic, antimony and bismuth. Base metal prices, treatment charges and penalties are generally established based upon prevailing market conditions by reference to prices in the world market, including on the LME. Currently, Doe Run Peru has entered into supply contracts, primarily with one-year terms, that meet approximately 95% of its concentrate requirements for fiscal 1998. Doe Run Peru pays concentrate suppliers for the majority of the metal content of the concentrates purchased and, thus, derives its operating profit primarily from treatment charges and penalties. In addition, Doe Run Peru generates operating profit from the sale of by-products, as well as from metals sold at a premium to the price paid for such metal. Moreover, since Doe Run Peru's metallurgical recoveries are typically in excess of the paid metal percentages, Doe Run Peru further increases its operating profit from the sale of the metal produced from such recoveries. The markets for Doe Run Peru's products are global and continue to grow as a result of worldwide economic growth. Given the diversity of its products and by-products, Doe Run Peru's financial performance is not solely dependent upon the prospects for any one of its products or by-products. Moreover, since Doe Run Peru is a processor of complex concentrates and does not presently own any mines from which it sources concentrates, Doe Run Peru's financial performance is less sensitive to the volatility of base metal prices. COMPETITIVE STRENGTHS The Company believes that its competitive strengths include the following: FOCUSED BUSINESS STRATEGY The production of lead and related products is Doe Run's primary business, whereas lead generally represents a small percentage of its competitors' overall operations. As a result, Doe Run believes that its ability to quickly recognize and respond to various trends that affect the lead industry and its customers provides Doe Run with a preferred status with its customers. This responsiveness, along with its reputation for excellent service, product quality and timely delivery, permits Doe Run to consistently realize premiums for its products, resulting in sales prices above the market price for lead quoted on the LME. With the assistance and direction provided by Doe Run, Doe Run Peru, as a private enterprise, is well positioned to recognize and respond to various trends that affect the smelting and refining industry, as well as its customers. Doe Run Peru will implement its business strategy with the operating flexibility to 8 (i) make discretionary capital expenditures and (ii) purchase an optimum mix of concentrate feedstock from a wider range of suppliers than it could under the constraints that existed as a government-owned enterprise. DIVERSE PROCESSING CAPABILITIES The combination of Doe Run's and Doe Run Peru's processing capabilities provides the Company greater diversity in its net sales and EBITDA. Specifically, with the Acquisition, approximately 74% and 75% of the Company's net sales for the twelve months ended October 31, 1997 and the three months ended January 31, 1998, respectively, were derived from (i) the treatment and processing of base metal concentrates, including copper, silver, zinc, lead and gold, (ii) the fabrication of lead and lead related products, (iii) the tolling of spent lead-acid batteries for major U.S. lead-acid battery manufacturers and (iv) the sale of zinc and copper concentrates. Such value-added tolling and other products and services are less sensitive to base metal price fluctuations. FAVORABLE ACCESS TO RAW MATERIALS Peru and its neighboring Latin American countries, primarily Bolivia, are significant producers of complex concentrates that contain multiple metals and high levels of impurities. Doe Run Peru obtains substantially all of its lead and zinc concentrates and approximately 80% of its copper concentrates from Peruvian sources. Since Doe Run Peru operates one of the few complex concentrate processing facilities in the world, Doe Run Peru obtains favorable pricing terms from its concentrate suppliers due to the complex nature of the concentrates and its proximity to the producing mines. As a result, Doe Run Peru believes that it operates at a geographic competitive advantage to comparable facilities located farther from their sources of complex concentrates. Currently, Doe Run Peru has entered into supply contracts, primarily with one-year terms, that meet approximately 95% of its concentrate requirements for fiscal 1998. FLEXIBLE MINING OPERATIONS Due to its extensive polymetallic ore resources, Doe Run has flexibility in developing its mining and milling plans to take advantage of prevailing market conditions for lead, zinc and copper. Depending on lead, zinc and copper prices, Doe Run has the ability, to a certain extent, to optimize its mine production by targeting certain ore grades in order to enhance operating margins. By maintaining such flexibility, Doe Run is able to reduce its exposure to the volatility of base metal prices. U.S. DOLLAR-BASED REVENUES The mining industry in which Doe Run Peru is a major participant is Peru's largest export industry, representing approximately 45% of Peru's total export sales in 1997. For the twelve months ended October 31, 1997 and the three months ended January 31, 1998, exports accounted for 78% and 77%, respectively, of Doe Run Peru's shipments and more than 79% and 72%, respectively, of its net sales. In addition, substantially all of Doe Run Peru's net sales are denominated in U.S. dollars. As a result, Doe Run Peru's net sales are less sensitive to foreign currency fluctuations. EXPERIENCED MANAGEMENT AND LABOR FORCE Doe Run's management team has extensive experience in the mining and metals production industry with an average of 23 years in the industry. The extensive experience of the Doe Run management team complements the skills of Doe Run Peru's executive personnel to provide Doe Run Peru with the strong management team necessary to compete as a private enterprise in the world markets. In addition, the Company employs a highly skilled workforce whose average tenure with the Company is more than 20 years. HIGH BARRIERS TO ENTRY Management believes that the capital costs and environmental requirements associated with constructing facilities comparable to those of the Company result in high barriers to entry for prospective 9 entrants. Management estimates that it would cost approximately $700 million to establish mining, milling and smelting operations with the production capacity and efficiency of Doe Run. Moreover, management is not aware of any significant mineral deposit in North America with lead grades and reserves similar to that of the Viburnum Trend. With respect to Doe Run Peru, management estimates that it would cost approximately $950 million to establish smelting and refining operations with the production capacity and efficiency of Doe Run Peru. Management believes that the cost and time commitment required to achieve commercial production for any new mining, milling, smelting or processing operation, including regulatory approvals, heightens the barriers to entry. BUSINESS STRATEGY The Company's business strategy is to improve its operations and financial performance by focusing on the following principal elements: INCREASE CAPACITY AND IMPROVE OPERATING EFFICIENCIES Doe Run is committed to improving its operating efficiencies through focused capital investments that increase capacity utilization, enhance productivity and lower costs. Since the acquisition of Doe Run by The Renco Group, Inc. ("Renco") in April 1994, Doe Run has completed approximately $34.4 million of capital investments through January 31, 1998 designed in part to reduce production costs and improve product quality. Additionally, Doe Run seeks to identify non-capital cost reduction opportunities throughout its operations. Doe Run has increased its primary lead production capacity from the original annual capacity of 225,000 tons to approximately 250,000 tons presently with minimal capital investment. In addition, Doe Run has increased its secondary lead production capacity from the original annual capacity of 60,000 tons to approximately 105,000 tons presently with minimal capital investment. The Company has identified a number of strategic initiatives designed to improve Doe Run Peru's operating efficiencies and its competitive position within the industry through focused capital investment. In furtherance of this strategy, Doe Run Peru has adopted a ten-year capital investment program of approximately $300.0 million (the "Capital Investment Program") in an effort to enhance various elements of Doe Run Peru's operations. The Capital Investment Program will target specific areas of Doe Run Peru's facilities, such as the copper and lead circuits, to improve product quality, increase capacity, improve productivity and reduce costs in the targeted area, thereby enhancing Doe Run Peru's net sales and EBITDA. In addition, the Capital Investment Program is designed to help achieve compliance with applicable environmental standards in Peru. MAINTAIN AND BUILD STRONG RELATIONSHIPS WITH STRATEGIC CUSTOMERS Through its ongoing research and development efforts and customer service initiatives, Doe Run strives to build and maintain strong relationships with its customers. Since lead is Doe Run's principal business, Doe Run sales and technical professionals are dedicated to working closely with Doe Run's customers to be responsive to their needs, such as small order quantities, specialized shapes, sizes and alloys, technical assistance and flexible deliveries. As a private enterprise, Doe Run Peru is implementing many of the successful customer service initiatives utilized by Doe Run to build and maintain strong relationships with its customers. Such initiatives will include ongoing research and development efforts, technical assistance and other customer service practices that will encourage a close working relationship with Doe Run Peru's customers. In addition, Doe Run Peru is shifting the focus of its marketing efforts to end users of its products from international trading companies. OPTIMIZE CONCENTRATE SUPPLY AT DOE RUN PERU As a private enterprise, Doe Run Peru is endeavoring to optimize the mix of complex concentrates from a wider range of suppliers than it purchased as a government-owned enterprise. Historically, Doe Run Peru obtained the vast majority of its concentrate requirements from Centromin mines, typically 10 pursuant to annual contracts. Given Doe Run Peru's unique position as one of the few processing facilities in the world for complex concentrates, Doe Run Peru will source its raw materials on a competitive basis within Peru from both Centromin mines and private mines, as well as from other Latin American suppliers. Currently, Doe Run Peru has entered into supply contracts, primarily with one-year terms, that meet approximately 95% of its concentrate requirements for fiscal 1998. GROW DOE RUN'S CORE LEAD BUSINESS Doe Run seeks to increase sales and operating cash flow through the growth of its core lead operations. Such efforts include increased sales of refined lead resulting from the expansion of its primary lead production capacity. In addition, Doe Run strives to expand its product offerings of value-added fabricated products including various shapes, sizes and alloys. Margins on fabricated products are relatively insensitive to lead price fluctuations because such fluctuations are generally reflected in the price of the end product. Doe Run is also growing its recycling and related tolling business with U.S. lead-acid battery manufacturers pursuant to contractual agreements under which recycled lead is returned to the supplier in exchange for a processing fee. Such processing fee is generally independent of lead prices. BROADEN REVENUE SOURCES THROUGH STRATEGIC ACQUISITIONS The Company seeks to broaden its revenue sources through the acquisition of related resource assets or businesses that capitalize on the combined experience of Doe Run and Doe Run Peru in mining, milling, smelting and refining base and precious metals. With respect to Doe Run, such opportunities, domestic or international, could be operations in primary or secondary lead production, lead fabrication or non-lead resource businesses. With respect to Doe Run Peru, such opportunities could include the acquisition of mining assets in Peru or other Latin American countries, including, without limitation, those presently undergoing privatization in Peru. The Acquisition reflects the Company's business strategy of broadening its revenue sources through a strategic acquisition, focusing on treatment and processing of base metal concentrates, as well as other metal related services. In particular, Doe Run Peru represented a unique opportunity for Doe Run to capitalize on Doe Run's extensive experience in efficiently managing mature smelter operations. Through the focused investment of capital and the implementation of Doe Run's operating practices, Doe Run Peru believes that it will increase its refined metals capacities and improve product quality, thereby enhancing financial performance through increased revenues and EBITDA. In April, 1998, Doe Run entered into a letter of intent with ASARCO Incorporated ("ASARCO") to purchase certain assets relating to the ASARCO's lead business in Missouri, including a smelter and refinery and two mines. The anticipated purchase price for these assets is approximately $50.0 million, plus contingent deferred purchase price payments over a period not to exceed five years, in an aggregate amount not to exceed $12.5 million. This transaction is subject to satisfactory completion of Doe Run's due diligence review and negotiation of a definitive agreement, as well as obtaining certain governmental and third party approvals. Doe Run has only recently commenced its due diligence review and currently cannot assess the likelihood that this transaction will be consummated. Accordingly, there can be no assurance that a definitive agreement related to this transaction will be entered into or that the required governmental approvals will be obtained. CONTROL OF THE COMPANY All of Doe Run's issued and outstanding capital stock is owned indirectly by Renco. In excess of 99% of the interests in Doe Run Peru is indirectly owned by Doe Run through Doe Run Cayman and Doe Run Mining (with a DE MINIMIS number of shares owned by employees of Doe Run Peru and Centromin pursuant to Peruvian law). Renco is 97.9% owned by Mr. Ira Leon Rennert, the Chairman of Doe Run and Chairman and Chief Executive Officer of Renco, and by trusts established for himself and members of his family (but of which he is not a trustee). As a result of such ownership, Mr. Rennert controls the Company. 11 THE EXCHANGE OFFER The Exchange Offer.................. $1,000 principal amount of Fixed Rate Exchange Notes and Floating Rate Exchange Notes will be issued in exchange for each $1,000 principal amount of Fixed Rate Old Notes and Floating Rate Old Notes, respectively, validly tendered pursuant to the Exchange Offer.

The Acquisition was structured as a direct subscription and payment for newly issued shares of Metaloroya representing a 51% ownership interest in Metaloroya and a contemporaneous purchase from Centromin of substantially all the previously outstanding shares, except for a DE MINIMIS number of shares purchased from Centromin pursuant to Peruvian law by employees of Centromin. In order to finance the Acquisition, Doe Run Mining borrowed $225.0 million in term loans under the Credit Agreement, dated as of October 23, 1997 (the "Existing Doe Run Mining Credit Facility"), among Doe Run Mining, as borrower, Doe Run, Doe Run Cayman, Doe Run Peru and Metaloroya, each as guarantors, and various financial institutions. In addition, Doe Run Mining received a $2.0 million capital contribution from Doe Run Cayman and a $23.0 million subordinated loan from Doe Run (the "Subordinated Loan"). Doe Run Mining used the foregoing funds to make a capital contribution to Doe Run Peru of approximately $248.0 million which was used to complete the Acquisition and for general corporate purposes. On December 30, 1997, the Merger of Metaloroya into Doe Run Peru was consummated with the surviving company being named Doe Run Peru S.R. Ltda. As part of the Subscription Agreement, Doe Run Peru is obligated to invest $120.0 million through October 23, 2002 (the "Investment Commitment") to expand and modernize Doe Run Peru's operations, including certain expenditures to comply with environmental regulations within Peru as set forth in the Programa de Adecuacion y Manejo Ambiental (Environmental Remedy and Management Program) (the "PAMA"), an environmental adjustment and management program. In the event that Doe Run Peru does not fulfill its obligations under the Investment Commitment, Doe Run Peru will be obligated to pay in 2002 a penalty payment to Centromin equal to 30% of any shortfall (a maximum of $36.0 million if none of the Investment Commitment is made during the five year period) (the "Penalty Payment"). As of March 31, 1998, Doe Run Peru had expended $1.2 million toward fulfillment of the Investment Commitment. In addition to term loans, the Existing Doe Run Mining Credit Facility provides for a working capital facility of $50.0 million, of which $3.0 million was drawn on the closing date of the Acquisition. As of October 31, 1997, Doe Run Mining had outstanding borrowings of $103.0 million under the Existing Doe Run Mining Credit Facility, $100.0 million in term loans and $3.0 million under the working capital facility. In addition, Doe Run Mining has an intercompany payable due to Doe Run Peru reflecting an interest free loan of $125.0 million made by Metaloroya to Doe Run Mining on the closing date of the Acquisition. The proceeds of the intercompany payable were used to reduce the outstanding term loans obtained by Doe Run Mining under the Existing Doe Run Mining Credit Facility to consummate the Acquisition. DOE RUN FINANCING As part of Renco's acquisition of Doe Run from Fluor Corporation ("Fluor") in April 1994, Doe Run undertook certain obligations to Fluor. These obligations included annual payments by Doe Run in exchange for an eight-year covenant not to compete, a profit participation arrangement and promissory notes (collectively, the "Fluor Indebtedness"). 18 Doe Run borrowed $130.0 million under a term loan (the "Doe Run Term Loan") pursuant to the Credit Agreement, dated as of October 23, 1997, among Doe Run, as borrower, DR Acquisition Corp. ("DRA"), as parent guarantor, Fabricated Products, Inc., as subsidiary guarantor, and various financial institutions. Doe Run used the net proceeds of the Doe Run Term Loan to pay $60.0 million to Fluor in full settlement of the Fluor Indebtedness, to make the Subordinated Loan and to make a $2.0 million capital contribution to Doe Run Cayman. In addition, Doe Run used a portion of the net proceeds of the Doe Run Term Loan to repay all amounts outstanding under Doe Run's then existing revolving credit facility and entered into a $100.0 million revolving credit facility (the "Existing Doe Run Revolving Credit Facility"). OLD NOTES OFFERING On March 12, 1998, Doe Run sold and issued the Old Notes (the "Old Notes Offering"). The net proceeds from the Old Notes Offering were approximately $248.6 million. Doe Run used $125.0 million of such net proceeds to make a deposit (the "Special Term Deposit") in a bank, which in turn loaned such amount (the "Back-to-Back Loan") to Doe Run Mining. The Special Term Deposit and the Back-to-Back Loan have payment terms that match the timing and amount of the payments on $125.0 million of the Fixed Rate Notes, except that additional interest of 0.50% for the first six months and 0.25% thereafter through September 2004 is payable on the Back-to-Back Loan. The Back-to-Back Loan is secured by the Special Term Deposit. Doe Run Mining used the proceeds of the Back-to-Back Loan to (i) repay amounts outstanding under the Existing Doe Run Mining Credit Facility and (ii) repay the Subordinated Loan to Doe Run of $23.0 million. Doe Run used the remaining approximately $123.6 million of the net proceeds from the Old Notes Offering, together with the proceeds from the repayment of the Subordinated Loan, to (i) repay amounts outstanding under the Doe Run Term Loan, (ii) repay amounts under the Existing Doe Run Revolving Credit Facility, (iii) redeem all of Doe Run's preferred stock held by Renco and pay accrued dividends thereon and (iv) pay related fees and expenses, including a transaction fee to Renco. The Old Notes Offering and the application of the proceeds therefrom are collectively referred to herein as the "Transactions." RISK FACTORS See "Risk Factors" for a discussion of certain factors that should be considered in evaluating an investment in the Exchange Notes. 19 SUMMARY HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA The following tables set forth historical financial data of (i) the Company for each of the three fiscal years ended October 31, 1997, which have been derived from the Company's audited consolidated financial statements, and for the three months ended January 31, 1997 and 1998 and as of January 31, 1998, which are unaudited, (ii) Doe Run Peru's predecessors ("Doe Run Peru's Predecessor") for each of the two fiscal years ended December 31, 1996, which have been derived from Doe Run Peru's Predecessor's audited consolidated financial statements, and for the period November 1, 1996 to October 23, 1997 (the date of consummation of the Acquisition) and the three months ended January 31, 1997, which are unaudited, (iii) Doe Run Cayman for the three months ended January 31, 1998, which are unaudited, and (iv) pro forma financial data of the Company for the fiscal year ended October 31, 1997 and the three months ended January 31, 1998 and as of January 31, 1998.

- ------------------------------ (a) EBITDA is defined as net income (loss) before extraordinary item plus the sum of net interest expense, income taxes and depletion, depreciation and amortization. The trends of EBITDA generally follow the trends of operating income. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" for a discussion of the recent trends of operating income. Information regarding EBITDA is presented because management believes that certain investors use EBITDA as one measure of an issuer's ability to service its debt. EBITDA should not be considered an alternative to, or more meaningful than, operating income or cash flow as an indicator of an issuer's operating performance. Furthermore, caution should be used in comparing EBITDA to similarly titled measures of other companies as the definitions of these measures may vary. (b) Pro forma cash interest expense is computed by removing substantially all historical cash interest expense due to the retirement of substantially all of the existing debt obligations of the Company and adding cash interest expense on the Old Notes, the Back-to-Back Loan and other obligations of $29.1 million, $14.5 million and $.1 million, respectively, net of cash interest income on the Special Term Deposit of $14.1 million, for the year ended October 31, 1997 and cash interest expense on the Old Notes and the Back-to-Back Loan of $7.3 million and $3.6 million, respectively, net of cash interest income on the Special Term Deposit of $3.5 million, for the three months ended January 31, 1998. (c) Pro forma net debt is pro forma total debt (including current portion), net of pro forma cash of $18.6 million and the $125.0 million Special Term Deposit. Pro forma total debt is computed by removing all of the existing debt obligations of the Company (except the industrial revenue bonds) and adding the Old Notes and the Back-to-Back Loan. (d) The average lead price per pound realized by Doe Run generally is at a premium over the average LME price. (e) Primary smelter lead tons per manshift is computed by dividing metal produced at Doe Run by the shifts required to produce the related tons. Shifts are computed by dividing the sum of actual hours worked during the period for hourly employees and 52 hours per week for salaried employees by eight hours. (f) Metaloroya was acquired by Doe Run Peru effective October 23, 1997. (g) Doe Run Cayman, a wholly-owned subsidiary of Doe Run, is the parent company of Doe Run Mining and currently has no independent operations. (h) Doe Run Cayman's net sales, operating income and EBITDA for the eight-day period October 23, 1997 to October 31, 1997 were $2.6 million, $.4 million and $.5 million, respectively. (i) These results include intercompany transactions. Net sales and cost of sales excluding the effects of intercompany transactions were $109.2 million and $88.7 million, respectively. (j) Adjusted EBITDA is defined as EBITDA adjusted for the following non-recurring charges: (i) for 1995, $2.5 million relating to personnel reduction costs, (ii) for 1996, $3.9 million relating to personnel reduction costs, $21.6 million relating to one-time environmental expenses and $3.6 million relating to privatization costs, (iii) for the period November 1, 1996 to October 23, 1997, $3.2 million relating to privatization costs and $2.0 million relating to personnel reduction costs and (iv) for the three months ended January 31, 1997, $.8 million relating to privatization costs and $.5 million relating to personnel reduction costs. (k) "LBMA" means the London Bullion Market Association. 21 RISK FACTORS PROSPECTIVE INVESTORS IN THE EXCHANGE NOTES SHOULD CONSIDER CAREFULLY THE RISK FACTORS SET FORTH BELOW, AS WELL AS THE OTHER INFORMATION APPEARING IN THIS PROSPECTUS, BEFORE MAKING AN INVESTMENT IN THE EXCHANGE NOTES. SUBSTANTIAL INDEBTEDNESS The Company has substantial indebtedness and debt service requirements. As of January 31, 1998, on a pro forma consolidated basis, the Company would have had $380.9 million of indebtedness outstanding (exclusive of anticipated aggregate commitments of $140.0 million under the New Revolving Credit Facilities). In addition, the Indenture permits the Company to incur certain other indebtedness. See "Description of the Notes--Certain Covenants--Limitation on Indebtedness." The Company's level of indebtedness will have several important effects on its future operations, including the following: (a) a significant portion of the Company's cash flow from operations will be dedicated to the payment of interest on its indebtedness and will not be available for other purposes, (b) the financial covenants and other restrictions contained in the New Revolving Credit Facilities require Doe Run and Doe Run Peru, as applicable, to meet certain financial tests and limit their ability to borrow additional funds or to dispose of assets and (c) the Company's ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes may be impaired. In addition, the ability of the Company to meet its debt service obligations and to reduce its total debt will be dependent upon its future performance, which will be subject to general economic conditions and to financial, business and other factors affecting its operations, many of which are beyond their control. Moreover, an inability of Doe Run or Doe Run Peru to meet the financial covenants contained in the New Revolving Credit Facilities or other indebtedness could result in an acceleration of amounts due thereunder. Doe Run was not in compliance with the minimum net worth and maximum leverage ratio covenants under the Doe Run Term Loan and the Existing Doe Run Revolving Credit Facility for the fiscal quarter ended January 31, 1998, for which Doe Run received waivers. RESTRICTIONS IMPOSED BY TERMS OF THE COMPANY'S INDEBTEDNESS The terms and conditions of the New Revolving Credit Facilities and the Indenture impose restrictions that affect, among other things, the ability of the Company to incur debt, pay dividends, make acquisitions, create liens, make capital expenditures and make certain investments. The ability of the Company to comply with the foregoing provisions can be affected by events beyond the Company's control. The breach of any of these covenants could result in a default under the Company's indebtedness, including the New Revolving Credit Facilities and the Indenture. In the event of any such default, depending on the actions taken by the lenders under the New Revolving Credit Facilities, Doe Run may be unable to make any payments of principal or interest on the Exchange Notes for a period of time. In addition, the lenders under the New Revolving Credit Facilities could elect to declare all amounts borrowed, together with accrued and unpaid interest, to be due and payable. If Doe Run or Doe Run Peru, as the case may be, were unable to repay such amounts, the lenders under the New Revolving Credit Facilities could proceed against certain collateral. If such indebtedness under the New Revolving Credit Facilities were to be accelerated, there can be no assurance that the assets of the Company would be sufficient to repay in full such indebtedness and the other indebtedness of the Company, including the Exchange Notes. See "Description of New Revolving Credit Facilities" and "Description of the Notes." DEPENDENCE ON CASH FLOW FROM PERUVIAN SUBSIDIARIES The Company is dependent upon payments from Doe Run Mining and Doe Run Peru, including loans, advances, distributions and dividends from Doe Run Peru, to meet a portion of its debt service requirements. Doe Run, Doe Run Mining and Doe Run Peru have entered into various intercompany agreements which provide for certain payments to Doe Run. See "Certain Transactions--Intercompany 22 Transactions." The Company believes that these intercompany agreements and the availability of dividends, distributions, loans or advances from Doe Run Mining or Doe Run Peru will provide Doe Run sufficient funds, combined with Doe Run's available resources, to adequately service Doe Run's debt service requirements. However, no assurance can be given that such amounts will be sufficient or that changes in the laws of Peru will not adversely affect such payments, loans, advances, distributions or dividends. See "--Governmental Regulation." VOLATILITY OF BASE METAL PRICES; TREATMENT CHARGES AND PENALTIES Base metal prices fluctuate and are affected by numerous factors beyond the Company's control, including expectations for inflation, speculative activities, global and regional demand and production, political and economic conditions and production costs in major producing regions. The aggregate effect of these factors is impossible for the Company to predict; however, these factors could have a material adverse effect on the results of operations, financial condition and liquidity of the Company. If the market price for lead falls below Doe Run's production costs and remains at such level for a sustained period, Doe Run will experience losses and may curtail or discontinue the development of a project or mining at one or more of its properties. In fiscal 1992 and 1993, Doe Run experienced operating losses due in part to unfavorable lead prices. As of March 31, 1998, the LME price for lead was $.26 per pound, which was below the ten-year average price of $.28 per pound. As a result of the recent lead price decreases, the Company expects that it will incur an operating loss in its U.S. operations that will adversely affect its EBITDA in fiscal 1998. There can be no assurance that lead prices will not decrease further in the future to levels resulting in operating losses for Doe Run. If base metal prices, treatment charges or penalties fall to such levels that Doe Run Peru cannot cover its production costs and remain at such levels for a sustained period, or result in the closure of the mines providing concentrate feedstock, Doe Run Peru will experience losses. There can be no assurance that base metal prices, treatment charges or penalties will not decrease in the future to levels resulting in operating losses for Doe Run Peru. While the Company may periodically use hedging techniques to reduce a portion of its exposure to the volatility of base metal prices, there can be no assurance that it will be able to do so effectively. See and "Management's Discussion and Analysis of Results of Operations and Financial Condition--Liquidity and Capital Resources--Hedging Activities." GOVERNMENTAL REGULATION The mining operations of Doe Run are subject to inspection and regulation by the Mine Safety and Health Administration of the Department of Labor ("MSHA") under provisions of the Federal Mine Safety and Health Act of 1977. All other operations of Doe Run are subject to inspection and regulation by the Occupational Safety and Health Administration of the Department of Labor ("OSHA") under the provisions of the Occupational Safety and Health Act of 1970. It is Doe Run's policy to comply with the directives and regulations of MSHA and OSHA. In addition, Doe Run takes such necessary actions as, in its judgment, are required to provide for the safety and health of its employees. MSHA and OSHA directives have had no material adverse impact on Doe Run's results of operations or financial condition, and Doe Run believes that it is substantially in compliance with the regulations promulgated by MSHA and OSHA; however, compliance with new, more stringent MSHA and/or OSHA directives could have a material adverse effect on results of operations, financial condition and liquidity of Doe Run. In connection with the Acquisition, Doe Run Peru, Doe Run Mining and Doe Run Cayman entered into a series of agreements (the "Stabilization Agreements") with two Peruvian government agencies, the Ministry for Energy and Mines (the "MEM") and the National Commission for Foreign Investments. Pursuant to terms of the Stabilization Agreements, the Peruvian government has guaranteed that, for a period of ten years from the date of the Acquisition, Doe Run Peru, Doe Run Mining and Doe Run 23 Cayman will not be adversely affected by changes in Peruvian legal regimes relating to, among other things, income tax, employment, free access to foreign exchange, right to remit investments and profits outside Peru and non-discrimination based on non-Peruvian ownership. No assurance can be given that the Peruvian government will not impose other conditions that may adversely affect Doe Run Peru's business, financial condition or results of operations or that there will not be changes in Peruvian legal regimes that will adversely affect Doe Run Peru, Doe Run Mining or Doe Run Cayman after the expiration of the Stabilization Agreements. ENVIRONMENTAL MATTERS AND CLAIMS Doe Run is subject to numerous federal, state and local environmental laws and regulations governing, among other things, air emissions, waste water discharge, solid and hazardous waste storage, treatment and disposal, and remediation of releases of hazardous materials. Doe Run also is a defendant in four lawsuits filed in 1995 claiming property damage and personal injury from alleged releases of lead from the Herculaneum smelter. Punitive damages are also being sought in these cases. Environmental laws and regulations have changed rapidly in recent years and may become more stringent in the future. Insurance against environmental risks (including potential for pollution or other hazards as a result of disposal of waste products occurring from mining, milling and smelting) is not generally available to Doe Run or to other companies within the industry. Should Doe Run be unable to fund fully the cost of compliance or of remediating an environmental problem, Doe Run might be required to suspend operations or enter into interim compliance measures requiring additional expenditures pending completion of the required remedy. Compliance with environmental laws and regulations, as well as personal injury and property and other damage claims, could have a material adverse effect on Doe Run's results of operations, financial condition and liquidity. See "Business--Doe Run--Environmental Matters." Doe Run Peru is subject to numerous environmental laws and regulations enacted in the last ten years in Peru governing, among other things, air emissions, waste water discharge, solid and hazardous waste storage, treatment and disposal, and remediation of releases of hazardous materials. The current and future application of these laws and regulations to Doe Run Peru is modified by certain agreements with the MEM, a Peruvian governmental agency. Given the developing nature of environmental law and enforcement policies in Peru, however, there can be no assurance that the Peruvian government will not in the future require compliance with additional environmental requirements that could adversely affect Doe Run Peru's business, financial condition or results of operations. Further, there can be no assurance that the Peruvian government or other interested persons will not seek changes in the future to the terms and conditions of any of the agreements made by Doe Run Peru with the MEM that may adversely affect Doe Run Peru's business, financial conditions or results of operations. Doe Run Peru also is subject to claims for alleged personal injury and property and other damages resulting from release of certain substances into the environment, including lead, to the extent such liabilities were not retained and are not satisfied by Centromin. Compliance with environmental laws and regulations, as well as personal injury and property and other damage claims, could have a material adverse effect on Doe Run Peru's business, financial condition or results of operations. Insurance against environmental risks (including potential for pollution or other hazards as a result of disposal of waste products occurring from exploration and production) is not generally available to Doe Run Peru or to other companies within the industry. To the extent Doe Run Peru is subject to environmental liabilities, the payment of such liabilities would reduce its available funds. Should Doe Run Peru be unable to fund fully the cost of remediating an environmental problem, it could be required to suspend operations or take interim compliance measures pending completion of the required remedy. See "Business--Doe Run Peru--Environmental Matters." OPERATING RISKS The business of mining is generally subject to a number of risks and hazards, including environmental hazards, industrial accidents, labor disputes, encountering unusual or unexpected geologic formations, 24 cave-ins, rockbursts, flooding and periodic interruptions due to inclement or hazardous weather conditions. Such risks could result in damage to, or destruction of, mineral properties or producing facilities, personal injury, environmental damage, delays in mining, monetary losses and possible legal liability. Although Doe Run maintains insurance within ranges of coverage consistent with industry practice, no assurance can be given that such insurance will be available at economically feasible premiums. In July 1992, Doe Run experienced a strike by the workers at the Herculaneum smelter resulting in metal output significantly lower than planned levels and higher operating expenses due to increased security costs and outside services. Although Doe Run's work force is no longer significantly unionized, there can be no assurance that Doe Run will not experience labor disputes in the future. In July and August 1993, production at the Herculaneum smelter was curtailed significantly due to flooding of the Mississippi River. There can be no assurance that Doe Run's operations will not be adversely affected in the future by flooding or other adverse conditions beyond Doe Run's control. See "Management's Discussion and Analysis of Results of Operations and Financial Condition." The business of smelting and refining complex concentrates generally is subject to a number of risks and hazards, including environmental hazards, industrial accidents and labor disputes. Such risks could result in personal injury, environmental damage, delays in operation, monetary losses and possible legal liability. Although Doe Run Peru maintains insurance within ranges of coverage consistent with industry practice, no assurance can be given that such insurance will be available at economically feasible premiums. See "Management's Discussion and Analysis of Financial Condition and Results of Operations." FACTORS RELATING TO DOE RUN DEPENDENCE ON A LIMITED NUMBER OF CUSTOMERS Doe Run relies heavily on a small number of customers which purchase a significant portion of its lead to produce lead-acid batteries. Johnson Controls, Inc. ("JCI") purchased lead and tolling services representing approximately 12% of Doe Run's fiscal 1997 net sales. In addition, Big River Zinc Corporation ("Big River") purchased zinc concentrates representing approximately 10% of Doe Run's fiscal 1997 net sales. The loss of any of Doe Run's largest customers or curtailment of purchases by such customers could have a material adverse effect on the results of operations, financial condition and liquidity of Doe Run. DEPENDENCE ON LEAD-ACID BATTERY USE Doe Run sells a significant portion of its lead production for use in lead-acid batteries. Lead-acid battery producers or their suppliers accounted for approximately 63% of Doe Run's fiscal 1997 net sales. The obsolescence of, or any curtailment in the use of, lead-acid batteries could have a material adverse effect on the results of operations, financial condition and liquidity of Doe Run. RESERVES The ore reserve figures presented in this Prospectus are, in large part, estimates made by Doe Run's technical personnel, and no assurance can be given that the indicated level of recovery of these metals will be realized. Market price fluctuations of lead, as well as increased production costs or reduced recovery rates, may render ore reserves containing relatively lower grades of mineralization uneconomic and may ultimately result in a restatement of reserves. Moreover, short-term operating factors relating to the ore reserves, such as the need for sequential development of ore bodies and the processing of new or different ore grades, may adversely affect Doe Run's results of operations in any particular accounting period. Doe Run assumes certain metal prices for its mineral reserve calculations, which approximate current market prices, but these lead prices may vary from current market prices based on a number of factors likely to influence lead prices over the near term. See "Business--Doe Run--Reserves." 25 EXPLORATION AND DEVELOPMENT Doe Run competes to acquire properties producing or capable of producing lead and other minerals, conducts exploration activities and engages in development projects. As a result of the competition for property, some of which is with companies with greater financial resources than Doe Run, Doe Run may be unable to acquire attractive mining properties on terms it considers acceptable. Mineral exploration is highly speculative in nature, involves many risks and frequently is nonproductive, and there can be no assurance that Doe Run's mineral exploration efforts will be successful. Once mineralization is discovered, it may take a number of years from the initial phases of drilling until production is possible, during which time the economic feasibility of production may change. Doe Run's ability to increase its production longevity is dependent on the successful development of new ore bodies and/or expansion of existing mining operations. It is possible that actual cash operating costs and economic returns of any and all development projects may materially differ from the estimated costs and returns. Accordingly, there can be no assurance that Doe Run's programs will yield new reserves to expand and replace existing reserves that are being depleted by current production. FACTORS RELATING TO DOE RUN PERU EXPANSION AND MODERNIZATION PROGRAM Doe Run Peru is undertaking an expansion and modernization program to enhance its competitive position and financial performance and to comply with certain environmental regulatory requirements (see "Business--Doe Run Peru--Environmental Matters") and the Subscription Agreement related to the Acquisition. Doe Run Peru believes that it will invest approximately $195.0 million over ten years in order to comply with such environmental requirements. Under the Subscription Agreement, Doe Run Peru has five years to fulfill its $120.0 million Investment Commitment. The maximum penalty that may be assessed for failure to comply with the Investment Commitment of the Subscription Agreement is 30% of the unfulfilled Investment Commitment. Doe Run Peru has developed a ten-year Capital Investment Program of approximately $300.0 million designed to improve its operations, as well as to address these environmental requirements and fulfill the Investment Commitment. Although management expects that cash from existing and future operations and available borrowings under the New Doe Run Peru Revolving Credit Facility and from anticipated borrowings in the future will be sufficient to cover the costs of Doe Run Peru's Capital Investment Program, there can be no assurance that Doe Run Peru will not be required to seek additional funds in order to complete its expansion and modernization program. Upon the incurrence of any borrowings under the New Doe Run Peru Revolving Credit Facility, there can be no assurance that Doe Run Peru's increased leverage will not have an adverse impact on Doe Run Peru's liquidity. If additional funds are necessary, there can be no assurance that Doe Run Peru will be able to obtain the required funds on terms and conditions acceptable to it. If such additional financing is unavailable, Doe Run Peru may have to delay completion of the expansion and modernization program until additional financing or sufficient internally generated funds become available, and any such delay could have a material adverse effect on the business, financial condition or results of operations of Doe Run Peru. AVAILABILITY OF CONCENTRATES Doe Run Peru, as presently constituted, does not own any of the mines from which it sources concentrates. Accordingly, Doe Run Peru purchases all of its concentrates feedstock requirements from unaffiliated mining operations. Doe Run Peru obtains approximately 84% of its copper concentrates, as well as all of its lead and zinc concentrates from the Peruvian domestic market. Doe Run Peru's current concentrate contracts are predominately for one-year terms expiring December 31, 1998. There can be no assurance that these contracts will be renewed or that, if renewed, they will not be on terms less favorable to Doe Run Peru. The closure of mines supplying concentrates due to exhaustion of reserves, low metals 26 prices or otherwise or the inability of Doe Run Peru to obtain concentrates, or to obtain them on favorable terms, could have a material adverse effect on the business, financial condition or results of operations of Doe Run Peru. SUPPLY AND COST OF RAW MATERIALS In addition to concentrates feedstock, Doe Run Peru's operations are heavily dependent on the supply of various raw materials, including water, hydroelectric power, oxygen, coal and fluxes. Doe Run Peru produces its oxygen requirements from its oxygen plant and extracts limestone and silica fluxes from deposits close to its facility. Doe Run Peru purchases its coal requirements through annual contracts based on market prices. Doe Run Peru has entered into a long-term contract with Empresa de Electricidad de Los Andes, S.A. ("Electroandes") to supply its electricity needs on satisfactory terms, though at costs higher than those paid by Doe Run Peru's Predecessor. The availability of raw materials could be affected by natural disasters or other factors beyond Doe Run Peru's control. Any protracted interruption in the availability of any raw materials could have a material adverse effect on the business, financial condition or results of operations of Doe Run Peru. LABOR MATTERS Approximately 89% of Doe Run Peru's workforce is represented by labor unions. Doe Run Peru recently entered into new one-year collective bargaining agreements with its labor unions. There can be no assurance that these short-term collective bargaining agreements will be renewed on terms as favorable to Doe Run Peru. Although management believes its present labor relations are generally good, in the past, work stoppages and strikes have occurred. There can be no assurance that a work stoppage or strike will not occur prior to the expiration of the current labor agreements or during negotiations for new labor agreements (including extensions of the existing labor agreements) or as to the effect of any such work stoppage or strike on Doe Run Peru's production levels. Work stoppages or other labor-related developments affecting Doe Run Peru could have a material adverse effect on the business, financial condition or results of operations of Doe Run Peru. See "Business--Doe Run Peru--Employees" and "--Benefit Plans." ENFORCEABILITY OF JUDGMENTS UNDER PERUVIAN LAW Substantially all of the assets of Doe Run Peru are located in Peru. In the event that the holders of Exchange Notes were to obtain a judgment in the United States against Doe Run Mining or Doe Run Peru and seek to enforce such judgment in Peru, the holders' ability to enforce the judgment in Peru would be subject to Peruvian laws regarding recognition and enforcement of foreign judgments. According to the rules of recognition and enforcement of foreign judgments provided by the Peruvian Civil Code, a judgment issued by a competent court outside Peru would be recognized and enforced by Peruvian courts provided that there is in effect a treaty between the country where said foreign court sits and Peru, regarding the recognition and enforcement of foreign judgments. In the absence of such treaty, as is the case between the United States and Peru, Peruvian courts will give to the foreign judgment the same force and treatment that is given by the country where such foreign court sits to the judgments enacted by Peruvian courts, PROVIDED that the foreign judgment complies with the following statutory limitations set forth in Article 2104 of the Peruvian Civil Code: (i) the judgment must not resolve matters for which exclusive jurisdiction of Peruvian courts applies (I.E., disputes relating to real estate located in Peru); (ii) the competence of the foreign court which issued the judgment must be recognized by Peruvian conflicts of law rules; (iii) the party against whom the judgment was obtained must have been properly served in connection with the foreign proceedings; (iv) the judgment of the foreign court must be a final judgment, not subject to any further appeal; (v) no pending proceedings may exist in Peru among the same parties and on the same subject; (vi) the judgment by the foreign court cannot be in violation of public policy; and (vii) the foreign court must grant reciprocal treatment to judgments issued by Peruvian courts. 27 FACTORS RELATING TO PERU POLITICAL AND ECONOMIC SITUATION IN PERU During the past 30 years, Peru has experienced political instability under both civilian and military governments. These governments have pursued various policies, including frequent intervention in the economic and social structure. Past governments have imposed controls on prices, exchange rates, local and foreign investment and international trade, restricted the ability of companies to dismiss employees, expropriated private sector assets, and prohibited the remittance of profits to foreign investors and payments to foreign creditors. In 1974, the government of Peru expropriated the assets of Doe Run Peru's Predecessor and transferred them to Centromin, a government-owned conglomerate. Since the current administration took office in July 1990, the Peruvian government has implemented a broad-based reform of Peru's political system, economy and social conditions, aimed at stabilizing the economy, restructuring the national government by reducing bureaucracy, privatizing state-owned companies, promoting private investment, developing and strengthening free markets, institutionalizing democratic representations, and enacting programs for the strengthening of basic services related to education, health, housing and infrastructure. Its then existing congressional body was dissolved in April 1992, and a new democratically elected congressional body was established in November 1992. A new Constitution was enacted and ratified in the fourth quarter of 1993. Under the current administration, inflation, as measured by the Peruvian Banco Central de Reserva (the "Central Bank"), has decreased from 7,649.7% in 1990 to 11.8% for 1996 and 6.5% for 1997. In addition, Peru's gross domestic product ("GDP"), as measured by the Central Bank, in real terms increased by 6.4% in 1993, 13.1% in 1994, 7.2% in 1995, 2.6% in 1996 and 7.4% in 1997. Notwithstanding the progress achieved in restructuring Peru's political institutions and revitalizing the economy during the administration's first term, there can be no assurance that the current administration or future administrations can sustain such progress. While the Peruvian economy has experienced strong growth in recent years, there can be no assurance that such growth will continue at similar rates in the future or at all. Doe Run Peru's financial condition and results of operations could be adversely affected by changes in economic or other policies of the Peruvian government, including the trend toward privatization, or other political or economic developments in Peru. EXCHANGE CONTROLS During the 1970s and 1980s, government policies restricted the ability of companies in Peru to, among other things, repatriate funds and import products, including oil, from abroad. In addition, currency exchange rates were strictly controlled and all export sales revenues were required to be deposited in the Central Bank where they were exchanged from U.S. dollars to the then local currency at less-than-market rates of exchange. The current Peruvian legal framework imposes no restrictions on the ability of a company operating in Peru to transfer foreign currency from Peru to other countries or to convert Peruvian currency into foreign currency or foreign currency into Peruvian currency. Prior to 1991, Peru had restrictive exchange controls and exchange rates. In the 1970s and 1980s, all foreign exchange proceeds were required to be deposited with the Central Bank. There can be no assurance that the Peruvian government will continue its current policy of permitting currency transfers and conversions without restriction or that Doe Run Peru would be able to service its debt obligations in a timely manner were the Peruvian government to reinstitute exchange controls. Notwithstanding the foregoing, certain of the Stabilization Agreements relate to free access to foreign exchange. However, no assurance can be given that there will not be changes in the Peruvian legal regimes that could adversely effect Doe Run Peru, Doe Run Mining or Doe Cayman upon expiration of the Stabilization Agreements. 28 TERRORIST ACTIVITY Peru experienced significant terrorist activity in the 1980s and early 1990s, during which period terrorist groups escalated their acts of violence against the government, the private sector and Peruvian residents. According to Peruvian government estimates, terrorist activity in Peru during the last sixteen years has resulted in an estimated 25,000 deaths and damage to property and the economy estimated at $25 billion. There has been substantial progress in suppressing terrorist activity since 1990, in part as a result of the arrest of the leaders and approximately 2,000 members of the two principal terrorist groups. Approximately 6,000 additional persons have agreed to cooperate with the government under an amnesty law. Notwithstanding the success achieved, some incidents of terrorist activity continue to occur, including the recently resolved hostage incident at the residence of the ambassador of Japan to Peru. Although Doe Run Peru has implemented certain anti-terrorist practices, there can be no assurance that future terrorist activity will not have a material adverse effect on the business, financial condition or results of operations of Doe Run Peru. INFLATION AND CURRENCY DEVALUATION Peru has in the past experienced high levels of inflation. However, the inflation rate in Peru, as measured by the Central Bank consumer price index, has fallen from 7,649.7% in 1990 to 139.2% in 1991, 56.7% in 1992, 39.5% in 1993, 15.4% in 1994, 10.2% in 1995, 11.8% in 1996 and 6.5% in 1997. Although the Peruvian government's stabilization plan has reduced inflation significantly, there can be no assurance that domestic inflation will not increase from its current level. In addition, the Peruvian currency has been devalued numerous times during the last twenty years. The devaluation rate, as measured by the Central Bank, was 4,012.9% in 1990, 77.0% in 1991, 69.8% in 1992, 31.9% in 1993, 1.4% in 1994, 6.0% in 1995, 12.6% in 1996 and 5.9% in 1997. A portion of the operating costs of Doe Run Peru are denominated in nuevos soles and therefore could be significantly affected by the rate of inflation in Peru. If inflation in Peru were to increase significantly without a corresponding devaluation of the nuevo sol, the financial condition and results of operations of Doe Run Peru could be materially and adversely affected. CONTROL BY RENCO Doe Run and the Guarantors are indirect subsidiaries of Renco, of which Mr. Ira Leon Rennert is the controlling shareholder. As a result of his indirect ownership of Doe Run and the Guarantors, Mr. Rennert is, and will continue to be, able to direct and control the policies of Doe Run and the Guarantors, including mergers, sales of assets and similar transactions. ABSENCE OF A PUBLIC MARKET The Exchange Notes will be new securities for which there is currently no public market. Doe Run does not intend to list the Exchange Notes on any national securities exchange or quotation system. The Initial Purchasers have advised Doe Run that they currently intend to make a market in the Exchange Notes, but they are not obligated to do so and, if commenced, may discontinue such market making at any time. Accordingly, there can be no assurance as to the development of any market or liquidity of any market that may develop for the Exchange Notes. To the extent that Old Notes are tendered and accepted in the Exchange Offer, the aggregate principal amount of Old Notes outstanding will decrease, with a resulting decrease in the liquidity of the market therefor. CONSEQUENCES OF FAILURE TO EXCHANGE Holders of Old Notes who do not exchange their Old Notes for Exchange Notes pursuant to the Exchange Offer will continue to be subject to the restrictions on transfer of the Old Notes set forth in the legend thereon as a consequence of the issuance of the Old Notes pursuant to an exemption from, or in a 29 transaction not subject to, the registration requirements of the Securities Act. In general, Old Notes may not be offered or sold, unless registered under the Securities Act, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. Doe Run currently does not anticipate that it will register the Old Notes under the Securities Act. USE OF PROCEEDS Doe Run will not receive any proceeds from the Exchange Offer. In consideration for issuing the Fixed Rate Exchange Notes and Floating Rate Exchange Notes as contemplated in this Prospectus, Doe Run will receive in exchange Fixed Rate Old Notes and Floating Rate Old Notes, respectively, of like principal amount, the terms of which are identical in all material respects to the Fixed Rate Exchange Notes and Floating Rate Exchange Notes, respectively. The Old Notes surrendered in exchange for Exchange Notes will be retired and canceled and cannot be reissued. Accordingly, issuance of the Exchange Notes will not result in any increase in the indebtedness of Doe Run. Doe Run has agreed to bear the expenses of the Exchange Offer pursuant to the Registration Rights Agreement. No underwriter is being used in connection with the Exchange Offer. See "Prospectus Summary--Recent Transactions--Old Notes Offering" for a description of the use of proceeds from the Old Notes Offering. 30 CAPITALIZATION The following table sets forth the consolidated capitalization of the Company as of January 31, 1998 on an actual basis and as adjusted for the Transactions.

(b) Pro forma interest expense reflects the elimination of historical interest expense due to the retirement of substantially all of the existing debt obligations. Interest expense, as adjusted, includes interest of $7.3 million on the Old Notes, interest on the Back-to-Back Loan of $3.6 million and amortization of debt issuance costs totaling $.3 million.

The trends of EBITDA generally follow the trends of operating income. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" for a discussion of recent trends of operating income. Information regarding EBITDA is presented because management believes that certain investors use EBITDA as one measure of an issuer's ability to service its debt. EBITDA should not be considered an alternative to, or more meaningful than, operating income or cash flow as an indicator of an issuer's operating performance. Furthermore, caution should be used in comparing EBITDA to similarly titled measures of other companies as the definitions of these measures may vary. (f) Pro forma cash interest expense is computed by removing substantially all historical cash interest expense due to the retirement of substantially all of the existing debt obligations of the Company and adding cash interest expense on the Old Notes and the Deposit Term Loan of $7.3 million and $3.6 million, respectively, net of cash interest income on the Special Term Deposit of $3.5 million. 36 THE DOE RUN RESOURCES CORPORATION UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS YEAR ENDED OCTOBER 31, 1997 (DOLLARS IN THOUSANDS)

Pro forma total debt is computed by removing all of the existing debt obligations of the Company (except the industrial revenue bonds) and adding the Old Notes and the Back-to-Back Loan. 38 SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA The following tables set forth historical financial data of (i) Doe Run's predecessor ("Doe Run's Predecessor") as of and for the year ended October 31, 1993 and for the five months ended March 31, 1994, which have been derived from Doe Run's Predecessor's unaudited consolidated financial statements, (ii) the Company as of and for the seven months ended October 31, 1994 and as of and for each of the three fiscal years ended October 31, 1997, which have been derived from the Company's audited consolidated financial statements, and for the three months ended January 31, 1997 and as of and for the three months ended January 31, 1998, which are unaudited, (iii) Doe Run Peru's Predecessor as of and for each of the three fiscal years ended December 31, 1996 and for the period January 1, 1997 to October 23, 1997 (the date of consummation of the Acquisition), which have been derived from Doe Run Peru's Predecessor's audited consolidated financial statements, and for the period November 1, 1996 to October 23, 1997 and the three months ended January 31, 1997, which are unaudited, and (iv) Doe Run Cayman as of and for the three months ended January 31, 1998, which are unaudited.

(FOOTNOTES COMMENCE ON FOLLOWING PAGE) 41 (a) Doe Run was acquired by Renco effective as of April 1, 1994. (b) Results for fiscal 1993 were affected by a strike at the Herculaneum smelter and curtailment of production at the Herculaneum smelter due to flooding of the Mississippi River. See "Management's Discussion and Analysis of Results of Operations and Financial Condition." (c) EBITDA is defined as net income (loss) before extraordinary item plus the sum of net interest expense, income taxes and depletion, depreciation and amortization. The trends of EBITDA generally follow the trends of operating income. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" for a discussion of the recent trends of operating income. Information regarding EBITDA is presented because management believes that certain investors use EBITDA as one measure of an issuer's historical ability to service its debt. EBITDA should not be considered an alternative to, or more meaningful than, operating income or cash flow as an indicator of an issuer's operating performance. Furthermore, caution should be used in comparing EBITDA to similarly titled measures of other companies as the definitions of these measures may vary. (d) Fixed charges consist of interest expense, capitalized interest, amortization of deferred financing costs and the portion of rental expense that is representative of interest expense. Earnings consist of income before taxes plus fixed charges less capitalized interest. (e) The average lead price per pound realized by Doe Run generally is at a premium over the average LME price. (f) Primary smelter lead tons per manshift is computed by dividing metal produced at Doe Run by the shifts required to produce the related tons. Shifts are computed by dividing the sum of actual hours worked during the period for hourly employees and 52 hours per week for salaried employees by eight hours. (g) Metaloroya was acquired by Doe Run Peru effective October 23, 1997. (h) Doe Run Cayman, a wholly-owned subsidiary of Doe Run, is the parent company of Doe Run Mining and currently has no independent operations. (i) Doe Run Cayman's net sales, operating income and EBITDA for the eight-day period October 23, 1997 to October 31, 1997 were $2.6 million, $.4 million and $.5 million, respectively. (j) These results include intercompany transactions. Net sales and cost of sales excluding the effects of intercompany transactions were $109.2 million and $88.7 million, respectively. (k) Adjusted EBITDA is defined as EBITDA adjusted for the following non-recurring charges: (i) for 1995, $2.5 million relating to personnel reduction costs, (ii) for 1996, $3.9 million relating to personnel reduction costs, $21.6 million relating to one-time environmental expenses and $3.6 million relating to privatization costs, (iii) for the period January 1, 1997 to October 23, 1997, $3.2 million relating to privatization costs and $1.5 million relating to personnel reduction costs, (iv) for the period November 1, 1996 to October 23, 1997, $3.2 million relating to privatization costs and $2.0 million relating to personnel reduction costs and (v) for the three months ended January 31, 1997, $.8 million relating to privatization costs and $.5 million relating to personnel reduction costs. 42 THE EXCHANGE OFFER TERMS OF THE EXCHANGE OFFER GENERAL In connection with the sale of Old Notes to the Initial Purchasers pursuant to the Purchase Agreement, dated March 6, 1998, among Doe Run, the Guarantors and the Initial Purchasers, the holders of the Old Notes became entitled to the benefits of the Registration Rights Agreement. Under the Registration Rights Agreement, Doe Run became obligated to (a) file a registration statement in connection with a registered exchange offer within 60 days after March 12, 1998, the date the Old Notes were issued (the "Issue Date"), and (b) cause the registration statement relating to such registered exchange offer to become effective within 150 days after the Issue Date. The Exchange Offer being made hereby, if consummated within the required time periods, will satisfy Doe Run's obligations under the Registration Rights Agreement. Doe Run understands that there are approximately beneficial owners of such Old Notes. This Prospectus, together with the Letter of Transmittal, is being sent to all such beneficial holders known to Doe Run. Upon the terms and subject to the conditions set forth in this Prospectus and in the accompanying Letter of Transmittal, Doe Run will accept all Old Notes properly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the Expiration Date. Doe Run will issue $1,000 principal amount of Fixed Rate Exchange Notes and Floating Rate Exchange Notes in exchange for each $1,000 principal amount of outstanding Fixed Rate Old Notes and Floating Rate Old Notes, respectively, accepted in the Exchange Offer. Holders may tender some or all of their Old Notes pursuant to the Exchange Offer. Based on an interpretation by the staff of the Commission set forth in the Morgan Stanley Letter, the Exxon Capital Letter and similar letters, Doe Run believes that Exchange Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be offered for resale, resold and otherwise transferred by any person who received such Exchange Notes, whether or not such person is the holder (other than Restricted Holders) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such Exchange Notes are acquired in the ordinary course of such holder's or other person's business, neither such holder nor such other person is engaged in or intends to engage in any distribution of the Exchange Notes and such holders or other persons have no arrangement or understanding with any person to participate in the distribution of such Exchange Notes. If any person were to be participating in the Exchange Offer for the purposes of participating in a distribution of the Exchange Notes in a manner not permitted by the Commission's interpretation, such person (a) could not rely upon the Morgan Stanley Letter, the Exxon Capital Letter or similar letters and (b) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction. Each broker-dealer that receives Exchange Notes for its own account in exchange for Old Notes, where such Old Notes were acquired by such broker-dealer as a result of market-making or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Old Notes where such Old Notes were acquired by such broker-dealer as result of market-making activities or other trading activities. Doe Run has agreed that, for a period of 180 days after consummation of the Exchange Offer, it will make this Prospectus, as it may be amended or supplemented from time to time, available to any broker-dealer for use in connection with any such resale. See "Plan of Distribution." 43 Doe Run will not receive any proceeds from the Exchange Offer. See "Use of Proceeds." Doe Run has agreed to bear the expenses of the Exchange Offer pursuant to the Registration Rights Agreement. No underwriter is being used in connection with the Exchange Offer. Doe Run shall be deemed to have accepted validly tendered Old Notes when, as and if Doe Run has given oral or written notice thereof to the Exchange Agent. The Exchange Agent will act as agent for the tendering holders of Old Notes for the purposes of receiving the Exchange Notes from Doe Run and delivering Exchange Notes to such holders. If any tendered Old Notes are not accepted for exchange because of an invalid tender or the occurrence of certain conditions set forth herein under "--Conditions" without waiver by Doe Run, certificates for any such unaccepted Old Notes will be returned, without expense, to the tendering holder thereof as promptly as practicable after the Expiration Date. Holders of Old Notes who tender in the Exchange Offer will not be required to pay brokerage commissions or fees or, subject to the instructions in the Letter of Transmittal, transfer taxes with respect to the exchange of Old Notes pursuant to the Exchange Offer. Doe Run will pay all charges and expenses, other than certain applicable taxes in connection with the Exchange Offer. See "--Fees and Expenses." In the event the Exchange Offer is consummated, Doe Run will not be required to register the Old Notes. In such event, holders of Old Notes seeking liquidity in their investment would have to rely on exemptions to registration requirements under the securities laws, including the Securities Act. See "Risk Factors--Consequences of Failure to Exchange." EXPIRATION DATE; EXTENSIONS; AMENDMENT The term "Expiration Date" shall mean the expiration date set forth on the cover page of this Prospectus, unless Doe Run, in its sole discretion, extends the Exchange Offer, in which case the term "Expiration Date" shall mean the latest date to which the Exchange Offer is extended. In order to extend the Expiration Date, Doe Run will notify the Exchange Agent of any extension by oral or written notice and will issue a public announcement thereof, each prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date. Such announcement may state that Doe Run is extending the Exchange Offer for a specified period of time. Doe Run reserves the right (a) to delay accepting any Old Notes, to extend the Exchange Offer or to terminate the Exchange Offer and not accept Old Notes not previously accepted if any of the conditions set forth herein under "--Conditions" shall have occurred and shall not have been waived by Doe Run (if permitted to be waived by Doe Run), by giving oral or written notice of such delay, extension or termination to the Exchange Agent, or (b) to amend the terms of the Exchange Offer in any manner deemed by it to be advantageous to the holders of the Old Notes. Any such delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by oral or written notice thereof. If the Exchange Offer is amended in a manner determined by Doe Run to constitute a material change, Doe Run will promptly disclose such amendment in a manner reasonably calculated to inform the holders of the Old Notes of such amendment, and Doe Run may extend the Exchange Offer for a period of up to ten business days, depending upon the significance of the amendment and the manner of disclosure to holders of the Old Notes, if the Exchange Offer would otherwise expire during such extension period. Without limiting the manner in which Doe Run may choose to make public announcement of any extension, amendment or termination of the Exchange Offer, Doe Run shall have no obligation to publish, advertise, or otherwise communicate any such public announcement, other than by making a timely release to the Dow Jones News Service. 44 INTEREST ON THE EXCHANGE NOTES The Exchange Notes will bear interest from March 12, 1998, payable semiannually on March 15 and September 15 of each year, commencing September 15, 1998, at the rate of 11 1/4% per annum in the case of the Fixed Rate Exchange Notes and at a rate per annum equal to LIBOR plus 6.29% in the case of the Floating Rate Exchange Notes. Interest on the Floating Rate Exchange Notes will be reset semi-annually. Holders of Old Notes whose Old Notes are accepted for exchange will be deemed to have waived the right to receive any payment in respect of interest on the Old Notes accrued up until the date of the issuance of the Exchange Notes. PROCEDURES FOR TENDERING To tender in the Exchange Offer, a holder must complete, sign and date the Letter of Transmittal, or a facsimile thereof, have the signatures thereon guaranteed if required by instruction 3 of the Letter of Transmittal, and mail or otherwise deliver such Letter of Transmittal or such facsimile, together with the Old Notes and any other required documents. To be validly tendered, such documents must reach the Exchange Agent on or before 5:00 p.m., New York City time, on the Expiration Date. The tender by a holder of Old Notes will constitute an agreement between such holder and Doe Run in accordance with the terms and subject to the conditions set forth herein and in the Letter of Transmittal. Delivery of all documents must be made to the Exchange Agent at its address set forth below. Holders may also request their respective brokers, dealers, commercial banks, trust companies or other nominees to effect such tender for such holders. The method of delivery of Old Notes and the Letter of Transmittal and all other required documents to the Exchange Agent is at the election and risk of the holders. Instead of delivery by mail, it is recommended that holders use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure timely delivery to the Exchange Agent on or before 5:00 p.m. New York City time, on the Expiration Date. No Letter of Transmittal or Old Notes should be sent to Doe Run or the Guarantors. Only a holder of Old Notes may tender such Old Notes in the Exchange Offer. The term "holder" with respect to the Exchange Offer means any person in whose name Old Notes are registered on the books of Doe Run or any other person who has obtained a properly completed bond power from the registered holder. Any beneficial holder whose Old Notes are registered in the name of his broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact such registered holder promptly and instruct such registered holder to tender on his behalf. If such beneficial holder wishes to tender on his own behalf, such registered holder must, prior to completing and executing the Letter of Transmittal and delivering his Old Notes, either make appropriate arrangements to register ownership of the Old Notes in such holder's name or obtain a properly completed bond power from the registered holder. The transfer of record ownership may take considerable time. Signatures on a Letter of Transmittal or a notice of withdrawal, as the case may be, must be guaranteed by a member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc. or a commercial bank or trust company having an office or correspondent in the United States (an "Eligible Institution") unless the Old Notes tendered pursuant thereto are tendered (a) by a registered holder who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or (b) for the account of an Eligible Institution. In the event that signatures on a Letter of Transmittal or a notice of withdrawal, as the case may be, are required to be guaranteed, such guarantee must be by an Eligible Institution. If the Letter of Transmittal is signed by a person other than the registered holder of any Old Notes listed therein, such Old Notes must be endorsed or accompanied by appropriate bond powers and a proxy 45 which authorizes such person to tender the Old Notes on behalf of the registered holder, in each case signed as the name of the registered holder or holders appears on the Old Notes. If the Letter of Transmittal or any Old Notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and unless waived by Doe Run, evidence satisfactory to Doe Run of their authority so to act must be submitted with the Letter of Transmittal. All questions as to the validity, form, eligibility (including time of receipt), and withdrawal of the tendered Old Notes will be determined by Doe Run in its sole discretion, which determination will be final and binding. Doe Run reserves the absolute right to reject any and all Old Notes not properly tendered or any Old Notes Doe Run's acceptance of which would, in the opinion of counsel for Doe Run, be unlawful. Doe Run also reserves the right to waive any irregularities or conditions of tender as to particular Old Notes. Doe Run's interpretation of the terms and conditions of the Exchange Offer (including the instructions in the Letter of Transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Old Notes must be cured within such time as Doe Run shall determine. None of Doe Run, the Guarantors, the Exchange Agent or any other person shall be under any duty to give notification of defects or irregularities with respect to tenders of Old Notes, nor shall any of them incur any liability for failure to give such notification. Tenders of Old Notes will not be deemed to have been made until such irregularities have been cured or waived. Any Old Notes received by the Exchange Agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned without cost to such holder by the Exchange Agent to the tendering holders of Old Notes, unless otherwise provided in the Letter of Transmittal, as soon as practicable following the Expiration Date. In addition, Doe Run reserves the right in its sole discretion to (a) purchase or make offers for any Old Notes that remain outstanding subsequent to the Expiration Date or, as set forth under "-- Conditions," to terminate the Exchange Offer in accordance with the terms of the Registration Rights Agreement and (b) to the extent permitted by applicable law, purchase Old Notes in the open market, in privately negotiated transactions or otherwise. The terms of any such purchases or offers will differ from the terms of the Exchange Offer. By tendering, each holder will represent to Doe Run that, among other things, (a) the Exchange Notes acquired pursuant to the Exchange Offer are being obtained in the ordinary course of business of such holder or other person, (b) neither such holder nor such other person is engaged in or intends to engage in a distribution of the Exchange Notes (c) neither such holder or other person has any arrangement or understanding with any person to participate in the distribution of such Exchange Notes, and (d) such holder or other person is not an "affiliate," as defined under Rule 405 of the Securities Act, of Doe Run or, if such holder or other person is such an affiliate, will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable. Each broker-dealer that receives Exchange Notes for its own account in exchange for Old Notes, where such Old Notes were acquired by such broker-dealer as a result of market-making or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Old Notes where such Old Notes were acquired by such broker-dealer as result of market-making activities or other trading activities. Doe Run has agreed that, for a period of 180 days after consummation of the Exchange Offer, it will make this Prospectus, as it may be amended or supplemented from time to time, available to any broker-dealer for use in connection with any such resale. See "Plan of Distribution." 46 Doe Run will not receive any proceeds from the Exchange Offer. See "Use of Proceeds." Doe Run has agreed to bear the expenses of the Exchange Offer pursuant to the Registration Rights Agreement. No underwriter is being used in connection with the Exchange Offer. The Old Notes were issued on March 12, 1998 and there is no public market for them at present. To the extent Old Notes are tendered and accepted in the Exchange Offer, the principal amount of outstanding Old Notes will decrease with a resulting decrease in the liquidity in the market therefor. Following the consummation of the Exchange Offer, holders of Old Notes will continue to be subject to certain restrictions on transfer. Accordingly, the liquidity of the market for the Old Notes could be adversely affected. GUARANTEED DELIVERY PROCEDURES Holders who wish to tender their Old Notes and (a) whose Old Notes are not immediately available or (b) who cannot deliver their Old Notes, the Letter of Transmittal or any other required documents to the Exchange Agent prior to the Expiration Date, may effect a tender if: (i) the tender is make through an Eligible Institution; (ii) prior to the Expiration Date, the Exchange Agent receives from such Eligible Institution a properly completed and duly executed Notice of Guaranteed Delivery (by facsimile transmission, mail or hand delivery) setting forth the name and address of the holder of the Old Notes, the certificate number or numbers of such Old Notes and the principal amount of Old Notes tendered, stating that the tender is being made thereby, and guaranteeing that, within three business days after the Expiration Date, the Letter of Transmittal (or facsimile thereof) together with the certificate(s) representing the Old Notes to be tendered in proper form for transfer and any other documents required by the Letter of Transmittal will be deposited by the Eligible Institution with the Exchange Agent; and (iii) such properly completed and executed Letter of Transmittal (or facsimile thereof) together with the certificate(s) representing all tendered Old Notes in proper form for transfer and all other documents required by the Letter of Transmittal are received by the Exchange Agent within three business days after the Expiration Date. WITHDRAWAL OF TENDERS Except as otherwise provided herein, tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date, unless previously accepted for exchange. To withdraw a tender of Old Notes in the Exchange Offer, a written or facsimile transmission notice of withdrawal must be received by the Exchange Agent at its address set forth herein prior to 5:00 p.m., New York City time, on the Expiration Date. Any such notice of withdrawal must (a) specify the name of the person having deposited the Old Notes to be withdrawn (the "Depositor"), (b) identify the Old Notes to be withdrawn (including the certificate number or numbers and principal amount of such Old Notes), (c) be signed by the Depositor in the same manner as the original signature on the Letter of Transmittal by which such Old Notes were tendered (including any required signature guarantees) or be accompanied by documents of transfer sufficient to have the Trustee with respect to the Old Notes register the transfer of such Old Notes into the name of the Depositor withdrawing the tender and (d) specify the name in which any such Old Notes are to be registered, if different from that of the Depositor. All questions as to the validity, form and eligibility (including time of receipt) of such withdrawal notices will be determined by Doe Run, whose determination shall be final and binding on all parties. Any Old Notes so withdrawn will be deemed not to have been validly tendered for purposes of the Exchange Offer and no Exchange Notes will be issued with respect thereto unless the Old Notes so withdrawn are validly retendered. Any Old Notes which have been tendered but which are not accepted for exchange will be returned to the holder thereof without cost to such holder as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn Old Notes may be retendered by following one of the procedures described above under "--Procedures for Tendering" at any time prior to the Expiration Date. 47 CONDITIONS Notwithstanding any other term of the Exchange Offer, Doe Run will not be required to accept for exchange, or exchange Exchange Notes for, any Old Notes not theretofore accepted for exchange, and may terminate or amend the Exchange Offer as provided herein before the acceptance of such Old Notes, if Doe Run or the holders of at least a majority in principal amount of Old Notes reasonably determine in good faith that any of the following conditions exist: (a) the Exchange Notes to be received by such holders of Old Notes in the Exchange Offer, upon receipt, will not be tradable by each such holder (other than a holder which is an affiliate of Doe Run at any time on or prior to the consummation of the Exchange Offer) without restriction under the Securities Act and the Exchange Act and without material restrictions under the blue sky or securities laws of substantially all of the states of the United States, (b) the interests of the holders of the Old Notes, taken as a whole, would be materially adversely affected by the consummation of the Exchange Offer or (c) after conferring with counsel, the Commission is unlikely to permit the making of the Exchange Offer prior to August 7, 1998. Pursuant to the Registration Rights Agreement, if an Exchange Offer shall not be consummated prior to the Exchange Offer Termination Date, Doe Run will be obligated to cause to be filed with the Commission a shelf registration statement with respect to the Old Notes (the "Shelf Registration Statement") as promptly as practicable after the Exchange Offer Termination Date and thereafter use its best efforts to have the Shelf Registration Statement declared effective. "Exchange Offer Termination Date" means the date on which the earliest of any of the following events occurs: (a) applicable interpretations of the staff of the Commission do not permit Doe Run to effect the Exchange Offer, (b) any holder of Notes notifies Doe Run that either (i) such holder is not eligible to participate in the Exchange Offer or (ii) such holder participates in the Exchange Offer and does not receive freely transferable Exchange Notes in exchange for tendered Old Notes or (c) the Exchange Offer is not consummated within 150 days after the Issue Date. If any of the conditions described above exist, Doe Run will refuse to accept any Old Notes and will return all tendered Old Notes to exchanging holders of the Old Notes. EXCHANGE AGENT State Street Bank and Trust Company has been appointed as Exchange Agent for the Exchange Offer. Questions and requests for assistance and requests for additional copies of this Prospectus or of the Letter of Transmittal and deliveries of completed Letters of Transmittal with tendered Old Notes should be directed to the Exchange Agent addressed as follows: BY MAIL BY HAND/OVERNIGHT DELIVERY State Street Bank and Trust Company State Street Bank and Trust Company Two International Place, 4th Floor 61 Broadway, 15th Floor Boston, Massachusetts 02110 New York, New York 10006 Attention: Claire Young--Corporate Trust Attention: Corporate Trust Department Department
Doe Run will indemnify the Exchange Agent and its agents for any loss, liability or expense incurred by them, including reasonable costs and expenses of their defense, except for any such loss, liability or expense caused by negligence or bad faith. FEES AND EXPENSES The expenses of soliciting tenders pursuant to the Exchange Offer will be borne by Doe Run. The principal solicitation for tenders pursuant to the Exchange Offer is being made by mail. Additional 48 solicitations may be made by officers and regular employees of Doe Run and its affiliates in person, by telephone or facsimile. Doe Run will not make any payments to brokers, dealers, or other persons soliciting acceptances of the Exchange Offer. Doe Run, however, will pay the Exchange Agent reasonable and customary fees for its services and will reimburse the Exchange Agent for its reasonable out-of-pocket expenses in connection therewith. Doe Run may also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this Prospectus, Letters of Transmittal and related documents to the beneficial owners of the Old Notes, and in handling or forwarding tenders for exchange. The expenses to be incurred in connection with the Exchange Offer, including fees and expenses of the Exchange Agent and Trustee and accounting and legal fees and expenses, will be paid by Doe Run, and are estimated in the aggregate to be approximately $500,000. Doe Run will pay all transfer taxes, if any, applicable to the exchange of Old Notes pursuant to the Exchange Offer. If, however, certificates representing Exchange Notes (or Old Notes for principal amounts not tendered or accepted for exchange) are to be delivered to, or are to be registered or issued in the name of, any person other than the registered holder of the Old Notes tendered, or if tendered Old Notes are registered in the name of any person other than the person signing the Letter of Transmittal, or if a transfer tax is imposed for any reason other than the exchange of Old Notes pursuant to the Exchange Offer, then the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted with the Letter of Transmittal, the amount of such transfer taxes will be billed directly to such tendering holder. ACCOUNTING TREATMENT Doe Run will not recognize any gain or loss for accounting purposes upon the consummation of the Exchange Offer. The expense of the Exchange Offer will be amortized by Doe Run over the term of the Exchange Notes under U.S. GAAP. 49 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Doe Run is the largest fully-integrated lead producer in North America and the second largest primary lead producer in the western world. Renco acquired Doe Run on April 1, 1994. Through its subsidiary Doe Run Peru, Doe Run operates one of the largest polymetallic processing companies in the world offering an extensive product mix of non-ferrous and precious metals, including copper, silver, lead, zinc and gold. Doe Run acquired Doe Run Peru on October 23, 1997. The combined capabilities of Doe Run and Doe Run Peru represent the largest primary lead producer in the western world. The following discussion and analysis of Doe Run and Doe Run Peru should be read in conjunction with the historical and pro forma financial statements of Doe Run and Doe Run Peru, and the notes thereto, and other financial information included elsewhere herein. DOE RUN Doe Run is engaged in exploration, development, mining and processing of base metals, primarily lead, and recycling of spent lead-acid batteries and other lead-bearing materials. Doe Run also fabricates and repairs lead-lined process equipment and lead products used in radiation shieldings, pollution control devices and medical equipment, and produces lead oxide for use in automotive batteries. Doe Run's principal product, refined lead, is actively quoted and traded on the LME. The LME provides an efficient and orderly market on which to trade lead and other non-ferrous metals. The market provides reference prices for worldwide pricing of activities relating to non-ferrous metals and provides for storage facilities to enable market participants to make or take physical delivery of approved brands of metals, such as Doe Run lead. Lead options and futures are also traded on the LME which enable participants to hedge against risks arising from price fluctuations. During fiscal 1993, Doe Run experienced certain non-recurring events, which contributed to Doe Run's operating losses during this period. Beginning in July 1992, Doe Run experienced a 29-month labor strike at its primary smelter. Although Doe Run was able to keep the smelter operational and satisfy most of its obligations during the strike by utilizing salaried employees from throughout Doe Run, as well as outside contractors, metal output fell significantly short of planned levels. Despite lower production levels, operating expenses increased due to substantially increased security costs and outside services. These factors combined to increase the conversion cost per ton of metal by approximately 25%. In July and August 1993, flooding of the Mississippi River caused Doe Run to shut down the Herculaneum smelter, thereby reducing fiscal 1993 production by approximately 10%. During the shut down, Doe Run continued to incur full production level costs. In addition to the non-recurring events at Doe Run, Doe Run's results of operations were adversely affected by lower lead prices for a portion of the period from 1993 to 1994. These lower lead prices were primarily a result of an increased supply of lead due to increased net exports of lead from Eastern Europe, the former Soviet Union and China. See "Industry--Lead." Subsequent to these events and its acquisition by Renco in April 1994, Doe Run undertook various changes to improve profitability under all market conditions and diversify its revenue sources. Specifically, as part of its program to improve profitability, Doe Run has increased production at both its Herculaneum and Buick smelting facilities. Primary lead production at Herculaneum grew from approximately 162,000 tons per year in fiscal 1993 to approximately 241,000 tons in fiscal 1997, while secondary production at Buick grew from approximately 66,000 tons per year in fiscal 1993 to approximately 102,000 tons in fiscal 1997. Recent blast furnace productivity improvements have increased the annual production capacity at Herculaneum from the original capacity of approximately 225,000 tons to approximately 250,000 tons presently. Increased production capacity enables Doe Run to lower unit costs by better leveraging its fixed cost base. 50 In recent years, Doe Run has made two strategic acquisitions of lead fabrication operations. Margins on these products are relatively insensitive to lead price fluctuations as Doe Run is generally able to reflect such fluctuations in the price of the end product. In addition, Doe Run has a growing tolling business with major U.S. lead-acid battery manufacturers pursuant to contractual agreements under which recycled lead is returned to the supplier in exchange for a processing fee which is largely independent of lead prices. The average LME price for refined lead was $.29 per pound in fiscal 1997. As of March 31, 1998, the LME price for lead was $.26 per pound, which was below the ten-year average price of $.28 per pound. Management believes that lead prices will remain relatively stable or will modestly increase for the remainder of fiscal 1998 and over the long term will reach historical industry averages. As a result of the recent lead price decreases, the Company expects that it will incur an operating loss in its U.S. operations that will adversely affect its EBITDA in fiscal 1998. RESULTS OF OPERATIONS THREE MONTHS ENDED JANUARY 31, 1998 COMPARED TO THREE MONTHS ENDED JANUARY 31, 1997 NET SALES for the three months ended January 31, 1998 (the "first quarter 1998") were $169.1 million compared to $65.8 million in the three months ended January 31, 1997 (the "first quarter 1997"). Of this increase, $109.2 million is attributable to the addition of Doe Run Peru resulting from the Acquisition on October 23, 1997. See "--Doe Run Peru--Results of Operations." Lead metal net sales decreased from $43.1 million to $41.0 million, a decrease of 4.9%. This change is attributable to an increase in lead metal sales volume of 10,322 tons, or 17.2%, resulting from improved production volume at both the primary and secondary smelters, offset by a $9.5 million reduction due to lower realized prices. The average LME price for lead metal decreased by $.0721 per pound, or 22.7%, from the first quarter 1997 to the first quarter 1998. As a result, Doe Run's net realized price was 18.9% lower in the first quarter of 1998 (realized prices are net of hedge transactions, see "--Liquidity and Capital Resources--Hedging Activities"). Sales by Seafab Metals Company ("Seafab") were $2.4 million lower in the first quarter 1998 compared to the first quarter 1997, primarily as a result of the planned relocation of the fabrication plant from Seattle, Washington to Casa Grande, Arizona which required approximately four weeks of down time. A slow down in oxide sales due to lower battery demand also contributed to the reduction. Tolling net sales for the first quarter 1998 decreased $1.1 million from the first quarter 1997 due to an 18.8% decrease in volume, which was the result of a drawdown in toll balances due to customers and a shift to metal sales. Other net sales were lower by $.3 million primarily due to lower zinc and lead concentrate volume, lower copper prices and reduced demand for large scale lead related maintenance and construction work at Lone Star Lead Construction Company ("Lone Star"), partially offset by improved copper concentrate volume, sales of imported zinc metal and improved zinc prices. COST OF SALES for the first quarter 1998 was $143.5 million compared to $52.9 million for the first quarter 1997. Of this increase, $88.7 million is attributable to the addition of Doe Run Peru. See "--Doe Run Peru--Results of Operations." Increased volumes of lead metal and copper concentrates offset by lower zinc and lead concentrate and toll volumes accounted for $5.2 million of the cost of sales increase. The cost of purchased lead concentrates and higher costs for salaries and fringe benefits, purchased lead metal, and purchased feed were more than offset by reduced purchased services and the impact of an 18.3% increase in lead metal production volume. As a result, the average cost per ton produced was approximately 0.9% lower in the first quarter 1998, reducing cost of sales by $2.2 million from the first quarter 1997. Lower volume at Seafab, primarily related to the relocation of the fabrication plant reduced cost of sales by $1.8 million. The sale of imported zinc metal increased cost of sales by $.8 million while other costs were lower by $.1 million. DEPLETION, DEPRECIATION AND AMORTIZATION for the first quarter 1998 increased by $2.1 million compared to the first quarter 1998. The addition of Doe Run Peru accounts for $1.7 million of the increase, while the 51 remainder of the increase is primarily due to depreciation of plant and equipment on recent capital additions. See "--Doe Run Peru--Results of Operations." SELLING, GENERAL AND ADMINISTRATIVE EXPENSES increased by $4.6 million in the first quarter 1998 compared to the first quarter 1997. The addition of Doe Run Peru accounts for an increase of $4.7 million, while other selling, general and administrative expenses were lower by $.1 million. See "--Doe Run Peru-- Results of Operations." OPERATING INCOME for the first quarter 1998 was $11.9 million compared to $5.8 million for the first quarter 1997. An increase of $14.2 million is attributable to the addition of Doe Run Peru. See "--Doe Run Peru--Results of Operations." The remaining change, a decrease of $8.1 million, is due to the factors discussed above. INTEREST EXPENSE for the first quarter 1998 was $5.9 million compared to $4.3 million for the first quarter 1997. The increase in indebtedness related to the Acquisition accounted for $2.6 million of this increase. The remaining decrease of $1.0 million was due to the refinancing of certain debt at more favorable interest rates and the impact of principal payments made during the first quarter 1997. INCOME TAX EXPENSE for the first quarter 1998 was $4.5 million compared to $.4 million for the first quarter 1997. Of this increase, $4.4 million is attributable to higher pretax earnings due to the Acquisition, offset by losses experienced domestically in the first quarter 1998. See "--Doe Run Peru--Results of Operations." In the first quarter 1998, Doe Run was unable to utilize all of its foreign tax credits relating to Peruvian tax provided for by Doe Run Peru. Management has recorded a valuation allowance against its net domestic deferred tax assets, including alternative minimum tax and foreign tax credit carryfowards, as it is uncertain, to the extent deferred tax assets exceed deferred tax liabilities, that the benefits will be realized. FISCAL 1997 COMPARED TO FISCAL 1996 NET SALES in fiscal 1997 (including the results for Doe Run Peru for the eight-day period October 23, 1997 (the date of the Acquisition) to October 31, 1997 (the "Acquisition Stub Period")) were $280.5 million compared to $274.9 million in fiscal 1996, an increase of 2.0%. Lead metal net sales decreased from $195.7 million to $185.1 million, a decrease of 5.4%. This change is attributable to an increase in lead metal sales volume of 17,046 tons or 6.4% offset by a $23.1 million reduction due to lower realized prices. The average LME price for lead metal decreased by $.0577 per pound or 16.4% from fiscal 1996 to fiscal 1997. As a result, the Company's net realized price was 11.1% less than fiscal 1996 (realized prices are net of hedge transactions; see "--Liquidity and Capital Resources--Hedging Activities"). Net sales of lead concentrates to third parties were reduced by $8.3 million in fiscal 1997 from fiscal 1996, as these lead concentrates were used in Doe Run's production. Tolling net sales for fiscal 1997 increased $7.3 million from fiscal 1996 due to a 17.9% increase in volume, as well as 25.5% increase in tolling processing charges per ton. Zinc concentrate net sales in fiscal 1997 increased $2.4 million or 10.8% from fiscal 1996 due primarily to higher realized prices. Copper concentrate net sales in fiscal 1997 decreased $3.6 million or 29.0% from fiscal 1996, and $1.8 million of this decrease is attributable to lower realized prices and $1.8 million is due to lower volume resulting from an emphasis on production of lead/zinc ore. The addition of Seafab, resulting from the acquisition of the assets of Seafab Metal Corporation in August 1996 added $15.9 million to net sales and the inclusion of Doe Run Peru from October 23, 1997, the acquisition date, through October 31, 1997 added $2.6 million. Other net sales were lower by $.1 million accounting for the remainder of the change. COST OF SALES for fiscal 1997 (including the results for Doe Run Peru for the Acquisition Stub Period) was $234.4 million, an increase of $18.9 million or 8.8% compared to fiscal 1996. Increased volumes of lead metal, tolling and zinc concentrates offset by lower copper and lead concentrate volumes accounted for $6.8 million of the increase. Higher costs of salaries and wages, materials and supplies, and purchased feed, 52 primarily related to increased production, were more than offset by reduced costs of purchased lead and the impact of greater production volume. As a result, the average cost per ton produced was approximately 1.1% lower than the prior year reducing cost of sales by $3.1 million. The addition of Seafab contributed $13.0 million to the cost of sales increase while the inclusion of Doe Run Peru added $2.0 million to cost of sales. Other costs of sales were higher by $.2 million accounting for the remainder of the change. DEPLETION, DEPRECIATION AND AMORTIZATION for fiscal 1997 (including the results for Doe Run Peru for the Acquisition Stub Period) increased by 7.8% primarily due to depreciation of property, plant and equipment on recent capital additions. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES for fiscal 1997 (including the results for Doe Run Peru for the Acquisition Stub Period) increased by $.9 million or 8.7% compared to fiscal 1996, primarily due to the addition of Seafab. EXPLORATION EXPENSE for fiscal 1997 (including the results for Doe Run Peru for the Acquisition Stub Period) was $2.7 million, a decrease of 7.1% from fiscal 1996. This change is attributable to less drilling on potential mineral properties. OPERATING INCOME for fiscal 1997 (including the results for Doe Run Peru for the Acquisition Stub Period) was $17.7 million compared to $32.8 million for fiscal 1996. This decrease is attributable to the factors discussed above. INTEREST EXPENSE for fiscal 1997 (including the results for Doe Run Peru for the Acquisition Stub Period) was $13.7 million or 4.2% less than fiscal 1996. Lower interest on subordinated notes of $.9 million was offset by the interest under the Existing Doe Run Mining Credit Facility entered into in connection with the acquisition of Doe Run Peru which added $.3 million to interest expense. INCOME TAX EXPENSE reflected an effective tax rate of 109% in fiscal 1997 and 34% in fiscal 1996. In both years, the income tax expense was provided on the basis of alternative minimum taxes paid, which exceeded the income tax provision based on pre-tax book income. Higher pre-tax book income in fiscal 1996 reduced the impact of the alternative minimum taxes paid on the effective tax rate for that year. Because of the uncertainty of the future benefit of net deferred tax assets, Doe Run has recorded a valuation allowance against its net deferred tax assets. FISCAL 1996 COMPARED TO FISCAL 1995 NET SALES in fiscal 1996 were $274.9 million compared to $225.1 million in fiscal 1995, an increase of 22.1%. Lead metal net sales increased from $167.2 million to $195.7 million, an improvement of 17.0%. The average LME price for lead metal was $.3524 per pound during fiscal 1996, $.0716 per pound greater than the average during fiscal 1995. The higher LME price and more favorable market conditions improved Doe Run's net realized price for both lead metal and lead concentrates generating increases in net sales of $13.7 million and $2.9 million, respectively. An increase in mine output along with production improvements at Doe Run's smelters generated a $14.8 million and $5.1 million increase in net sales from lead metal and lead concentrate volume, respectively. Zinc and copper concentrate net sales increased by $4.1 million and $3.6 million, respectively, primarily as a result of increased sales volume. The addition of Lone Star, resulting from the acquisition of the assets of Lone Star Lead Construction Corp. in August 1995, and the addition of Seafab in August 1996 contributed $7.7 million to the increase in net sales. Such increases were offset by a $2.1 million decrease in net sales due to lower realized prices on copper concentrates and changes in other by-products. COST OF SALES for fiscal 1996 was $215.5 million, an increase of $35.1 million or 19.5% over fiscal 1995. The greater production volume, primarily of lead metal and lead, copper and zinc concentrates, accounts for $20.3 million of this increase. Higher costs for certain raw materials, supplies, purchased services, and increased incentive compensation of $1.9 million resulting from significantly improved profitability were partially offset by the impact of greater production volume. As a result, the average cost per ton produced 53 in fiscal 1996 was approximately 2.6% higher than the prior year, adding $6.1 million to cost of sales. The inclusion of Lone Star and Seafab contributed $6.4 million to the increase, while changes in other costs, primarily smelter by-products, account for the remaining $.4 million increase. DEPLETION, DEPRECIATION AND AMORTIZATION for fiscal 1996 increased by $1.2 million or 9.4% from fiscal 1995 primarily due to depreciation of property, plant and equipment related to recent capital expenditures. SELLING, GENERAL AND ADMINISTRATIVE expenses increased by $1.7 million or 19.9% from fiscal 1995 to fiscal 1996. Higher incentive compensation as a result of higher profitability accounts for $1.1 million of this increase. Increased legal costs associated with various defenses of lawsuits (see "Business-Environmental Matters") and consulting costs for operational efficiency studies initiated during fiscal 1996 account for the remainder of this increase. EXPLORATION EXPENSE increased by $1.0 million or 51.2% in fiscal 1996 compared to fiscal 1995 due primarily to increased drilling on potential mineral properties. OPERATING INCOME for fiscal 1996 was $32.8 million compared to $21.9 million for fiscal 1995. This increase is attributable to the factors discussed above. INCOME TAX EXPENSE reflected an effective tax rate of 34% in fiscal 1996 and 43% in fiscal 1995. In both years, income tax expense was provided on the basis of alternative minimum taxes paid, which exceeded the income tax provision based on pre-tax book income. Higher pre-tax book income in fiscal 1996 reduced the impact of the alternative minimum taxes paid on the effective tax rate for that year. Because of the uncertainty of the future benefit of net deferred tax assets, Doe Run has recorded a valuation allowance against its net deferred tax assets. DOE RUN PERU Doe Run Peru is engaged in the smelting and refining of concentrates of polymetallic ores, including copper, silver, zinc, lead and gold, which are sold primarily to customers outside of Peru. These activities are the same as those that were carried out by Metaloroya and Centromin. Metaloroya was established on September 20, 1997, and commenced operations on October 23, 1997, as the successor company to the operations of the former La Oroya Metallurgical Complex of Centromin, pursuant to the Subscription Agreement. Given the diversity of its products and by-products, Doe Run Peru's financial performance is not solely dependent upon the prospects for one of its products or by-products. Moreover, since Doe Run Peru is a processor of complex concentrates and does not presently own any mines from which it sources concentrates, Doe Run Peru's financial performance is less sensitive to the volatility of base metal prices. The primary factors affecting Doe Run Peru's results of operations are (i) commercial terms under which Doe Run Peru purchases concentrates and (ii) Doe Run Peru's operating costs and other expenses. RESULTS OF OPERATIONS THREE MONTHS ENDED JANUARY 31, 1998 COMPARED TO THREE MONTHS ENDED JANUARY 31, 1997 NET SALES increased 3.3% from $108.2 million in the first quarter 1997 to $111.8 million in the first quarter 1998. Net sales of copper decreased 20.9% from $36.7 million in the first quarter 1997 to $29.0 million in the first quarter 1998, due to a decrease in the average price per pound of 22.9% from $1.05 in the first quarter 1997 to $.81 in the first quarter 1998, offset by an increase in the volume of 2.1% from 17,515 tons in the first quarter 1997 to 17,883 tons in the first quarter 1998. Net sales of silver increased 43.7% from $24.5 million in the first quarter 1997 to $35.2 million in the first quarter 1998, due to a volume increase of 30.0% from 5.0 million ounces in the first quarter 1997 to 6.5 million ounces in the first quarter 1998, as well as an increase in the average price per ounce of 10.6% from $4.89 in the first quarter 1997 to $5.41 in the first quarter 1998. Net sales of gold increased 2.7% from $3.7 million in the 54 first quarter 1997 to $3.8 million in the first quarter 1998, due to a volume increase of 30.3% from 9,870 ounces in the first quarter 1997 to 12,860 ounces in the first quarter 1998, offset by a decrease in the average price per ounce of 21.2% from $377.1 in the first quarter 1997 to $297.2 in the first quarter 1998. Refined lead net sales decreased 16.3% from $17.2 million in the first quarter 1997 to $14.4 million in the first quarter 1998, due to a decrease in the average price per pound of 18.2% from $.33 in the first quarter 1997 to $.27 in the first quarter 1998, offset by a volume increase of 3.1% from 26,093 tons in the first quarter 1997 to 26,905 tons in the first quarter 1998. Refined zinc net sales increased 12.0% from $17.5 million in the first quarter 1997 to $19.6 million in the first quarter 1998, due primarily to an increase in the average price per pound of 10.4% from $.48 in the first quarter 1997 to $.53 in the first quarter 1998 and a volume increase of 0.6% from 18,264 tons in the first quarter 1997 to 18,368 tons in the first quarter 1998. By-products net sales increased by 14.1% from $8.5 million in the first quarter 1997 to $9.7 million in the first quarter 1998 primarily due to the sale of 2,230 tons of bullion lead for $2.1 million in the first quarter 1998. No bullion lead was sold in the first quarter 1997. This increase was offset by a decrease in net sales of blister copper of 18.8% from $6.4 million in the first quarter 1997 to $5.2 million in the first quarter 1998, due to a decrease in the average price per pound of 10.6% from $1.32 in the the first quarter 1997 to $1.18 in the first quarter 1998 and a volume decrease of 9.6% from 2,438 tons in the first quarter 1997 to 2,203 tons in the first quarter 1998. COST OF SALES increased 5.3% from $86.3 million in the first quarter 1997 to $90.9 million in the first quarter 1998 due to higher power costs resulting from a new contract as of October 23, 1997, and an increase in production volume of approximately 6.0% and the inclusion of $1.1 million of workers' profit sharing expense which was classified as cost of sales in the first quarter 1997. These increases were partially offset by the impact of improved metallurgical recoveries. DEPRECIATION AND AMORTIZATION EXPENSES increased 21.4% from $1.4 million in the first quarter 1997 to $1.7 million in the first quarter 1998, primarily due to the change in asset bases in connection with the Acquisition. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (INCLUDING MARKETING EXPENSE) decreased 21.7% from $6.0 million in the first quarter 1997 to $4.7 million in the first quarter 1998. Selling expenses decreased 25.0% from $1.6 million in the first quarter 1997 to $1.2 million in the first quarter 1998, due to a decrease in freight expenses and sales commissions based on new terms agreed with third parties. General and administrative expenses increased 30.8% from $2.6 million in the first quarter 1997 to $3.4 million in the first quarter 1998 primarily due to audit and legal fees and other expenses related to the Old Notes Offering. Of the decrease in selling, general and administrative expenses, $.5 million was due to personnel reduction costs in the first quarter 1997 related to the personnel reduction program undertaken by Centromin, which was completed during 1997. Workers' profit sharing cost, which was $1.2 million in the first quarter 1997, was classified in costs of sales in the first quarter 1998. OPERATING INCOME was $14.5 million in each of the first quarter 1997 and 1998. The factors discussed above yielded no net change in operating income. INTEREST AND BANK CHARGES increased from $.5 million in the first quarter 1997 to $2.9 million in the first quarter 1998, due primarily to the loans obtained to finance the Acquisition. INCOME TAX increased 2.3% from $4.3 million in the first quarter 1997 to $4.4 million in the first quarter 1998 as a result of the inclusion of non-deductible expenses to the pretax income in accordance with Peruvian tax regulations. NET INCOME decreased 22.5% from $9.8 million in the first quarter 1997 to $7.6 million in the first quarter 1998 as a result of the factors discussed above. 55 PERIOD FROM JANUARY 1, 1997 TO OCTOBER 23, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996 The results of operations for the period January 1, 1997 to October 23, 1997 are not necessarily comparable with the results of operations for the year ended December 31, 1996 due to the shorter period included in the 1997 results. NET SALES decreased 22.8% from $456.8 million in 1996 to $352.8 million in the 1997 period, due principally to the shorter period in 1997, changes in the mix of existing products and a significant blister copper sale made in 1996. Net sales of copper decreased 17.8% from $148.4 million in 1996 to $122.0 million in the 1997 period, due to a volume decrease of 20.4% from 71,287 tons in 1996 to 56,725 tons. This decrease included a volume decrease of 96.6% from 5,537 tons in 1996 to 186 tons in the 1997 period, when two years' of accumulated stock of copper blister was sold. The volume changes were offset partially by an increase in the average price per pound of 3.8% from $1.04 in 1996 to $1.08 in the 1997 period. Net sales of silver decreased 25.9% from $111.0 million in 1996 to $82.2 million in the 1997 period, due to a volume decrease of 18.4% from 21.2 million ounces in 1996 to 17.3 million ounces in the 1997 period as well as a decrease in the average price per ounce of 10.2% from $5.23 in 1996 to $4.70 in the 1997 period. Net sales of gold decreased 42.2% from $20.4 million in 1996 to $11.8 million in the 1997 period, due to a volume decrease of 34.4% from 52,277 ounces in 1996 to 34,305 ounces in the 1997 period and a decrease in the average price per ounce of 11.9% from $389.5 in 1996 to $342.9 in the 1997 period. Refined lead net sales decreased 31.6% from $76.3 million in 1996 to $52.2 million in the 1997 period, due to a volume decrease of 16.3% from 104,063 tons in 1996 to 87,135 tons in the 1997 period and a decrease in the average price per pound of 18.9% from $.37 in 1996 to $.30 in the 1997 period. Refined bismuth net sales increased 37.5% from $4.8 million in 1996 to $6.6 million in the 1997 period, due primarily to a volume increase of 53.0% from 660 tons in 1996 to 1,010 tons in the 1997 period and a decrease in the average refined bismuth price per pound of 10.3% from $3.30 to $2.96. COST OF SALES decreased 23.0% from $397.2 million in 1996 to $305.9 million in the 1997 period, due principally to the shorter period, 18.1%, as well as lower labor expenses resulting from the personnel reduction costs carried out in 1996. DEPRECIATION AND AMORTIZATION EXPENSES decreased 13.0% from $5.4 million in 1996 to $4.7 million in the 1997 period, due primarily to the shorter period in 1997 as well as the adjustment to the depreciation of initial balances of fixed assets made in 1996. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (INCLUDING MARKETING EXPENSE) decreased 20.7% from $17.4 million in 1996 to $13.8 million in 1997. Personnel reduction costs decreased 61.5% from $3.9 million in 1996 to $1.5 million in the 1997 period, as Doe Run Peru had substantially completed its personnel reduction program in 1996. Selling, marketing and administrative expenses were lower by $2.3 million, or 18.6%, in the 1997 period, primarily due to the shorter period in 1997. Worker's profit sharing was greater by $1.1 million, or 91%, in the 1997 period due primarily to improved profitability. OPERATING INCOME declined from $36.9 million in 1996 to $28.3 million in the 1997 period due to the factors discussed above. INTEREST AND BANK CHARGES decreased 75.8% from $3.3 million in 1996 to $0.8 million in the 1997 period, due primarily to a decrease of debt levels through 1997, which was offset by the effects of a slight increase in the weighted average interest rate in the 1997 period. OTHER, NET decreased 94.9% from $23.5 million in 1996 to $1.2 million in the 1997 period. In 1996, the Company incurred special charges related primarily to (i) costs related to relocating residents away from the metallurgical complex of La Oroya, such as demolition, and construction of apartments, schools and parks at a new location and (ii) an accrual to provide for estimated future expenditures under the PAMA of $21.5 million. 56 INCOME TAX increased 92.7% from $4.1 million in 1996 to $7.9 million in the 1997 period as a result of the increase in pretax income due to reasons discussed above. NET INCOME increased 212.2% from $5.9 million in 1996 to $18.4 million in the 1997 period, due to reasons discussed above. YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995 NET SALES increased 1.3% from $450.9 million in 1995 to $456.8 million in 1996, due principally to sale of a new product and changes in the mix of existing products. In 1996, Doe Run Peru commenced sale of a new product, blister copper, amounting to $14.0 million. Refined lead net sales increased 29.4% from $58.9 million in 1995 to $76.3 million in 1996, due to a volume increase of 5.4% from 98,746 tons in 1995 to 104,063 tons in 1996 and an increase in the average price per pound of 23.3% from $.30 in 1995 to $.37 in 1996. Refined bismuth net sales also increased 17.1% from $4.1 million in 1995 to $4.8 million in 1996, due primarily to a volume increase of 26.7% from 574 tons in 1995 to 728 tons in 1996 and a decrease in the average price per pound of 6.8% from $3.54 in 1995 to $3.30 in 1996. Although the volume of refined copper sold in 1996 increased 1.8% from 70,006 tons in 1995 to 71,287 tons in 1996, the decrease in the price per pound of refined copper of 21.8% from $1.33 in 1995 to $1.04 in 1996 resulted in a decrease in net sales of refined copper of 20.6% from $186.9 million in 1995 to $148.4 million. COSTS OF SALES decreased 0.1% from $397.5 million in 1995 to $397.2 million in 1996, due to the effects of the 1996 personnel reduction program, which was offset by the additional cost related to the use of independent contractors in place of terminated employees. This reduction in cost was achieved despite a moderate increase in the volume of concentrates processed in 1996. DEPRECIATION AND AMORTIZATION EXPENSES increased 14.9% from $4.7 million in 1995 to $5.4 million in 1996 due primarily to adjustment of the depreciation of the initial balances of the fixed assets. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (INCLUDING MARKETING EXPENSE) increased by 8.8% from $16.0 million in 1995 to $17.4 million in 1996. Personnel reduction costs increased 56.0% from $2.5 million in 1995 to $3.9 million in 1996 due to the implementation of a second personnel reduction program of 600 workers in 1996. Administrative expenses increased 26.7% from $4.5 million in 1995 to $5.7 million in 1996 primarily due to the shift to use of independent contractors in place of employees. Selling and marketing expenses increased 11.7% from $6.0 million in 1995 to $6.7 million in 1996 due to the increased volume of metal sold in 1996 as discussed above. OPERATING INCOME increased from $32.7 million in 1995 to $36.9 million in 1996 due to the factors discussed above. INTEREST AND BANK CHARGES increased 57.1% from $2.1 million in 1995 to $3.3 million in 1996, due primarily to higher average borrowings, which was offset by the effects of a slight decrease in the weighted average interest rate in 1996. OTHER, NET increased from $1.8 million in 1995 to $23.5 million in 1996. In 1996, Doe Run Peru incurred special charges related primarily to (i) costs related to relocating residents away from the metallurgical complex of La Oroya, such as demolition, and construction of apartments, schools and parks at a new location and (ii) an accrual to provide for estimated future expenditures under the PAMA of $21.5 million. INCOME TAX decreased 60.2% from $10.3 million in 1995 to $4.1 million in 1996 as a result of the decrease in pretax income due primarily to the special charges discussed above. NET INCOME decreased 68.1% from $18.5 million in 1995 to $5.9 million in 1996, due to reasons discussed above. As a percentage of net sales, net income was 4.1% in 1995 compared to 1.3% in 1996. 57 LIQUIDITY AND CAPITAL RESOURCES The Company's liquidity requirements arise from working capital requirements, capital investments and interest payment obligations. Doe Run's primary available sources of liquidity are cash provided by operating activities and existing cash balances in the United States, as well as cash receipts from certain management services and sales agency agreements, loans, advances, distributions or dividends between Doe Run and Doe Run Peru. See "Certain Transactions--Intercompany Transactions." Doe Run also has available the New Doe Run Revolving Credit Facility that provides for advances by the lender to a maximum of $100.0 million less outstanding letters of credit, based on specific percentages of eligible receivables and inventories. As of March 31, 1998, $5.0 million was outstanding, exclusive of $4.3 million of letters of credit, under the New Doe Run Revolving Credit Facility. See "Description of New Revolving Credit Facilities--New Doe Run Revolving Credit Facility." Doe Run was not in compliance with the minimum net worth and maximum leverage ratio covenants under the Doe Run Term Loan and the Existing Doe Run Revolving Credit Facility for the fiscal quarter ended January 31, 1998, for which Doe Run received waivers. Doe Run repaid all amounts outstanding under the Existing Doe Run Credit Facility with the net proceeds of the Old Notes Offering. Doe Run Peru's primary available source of liquidity is cash provided by operating activities. Doe Run Peru will also have available the New Doe Run Peru Revolving Credit Facility that will provide for advances by the lender to a maximum of $40.0 million less outstanding letters of credit, based upon specific percentages of eligible receivables and inventories. Upon consummation of the Transactions, no amounts are expected to be outstanding under the New Doe Run Peru Revolving Credit Facility, other than existing letters of credit. See "Description of New Revolving Credit Facilities--New Doe Run Peru Revolving Credit Facility." With respect to Doe Run, in the first quarter 1998, $10.2 million was used in operating activites, $3.4 million was used in investing activities and $13.0 million was provided by financing activities, and in fiscal 1997, $18.0 million was provided by operating activities, $141.7 million was used in investing activities and $132.6 million was provided by financing activities. As part of its financing activities, Doe Run borrowed $130.0 million under the Doe Run Term Loan to finance, in part, the Acquisition. The net proceeds of the Doe Run Term Loan were used to pay $60.0 million to Fluor in full settlement of the Fluor Indebtedness, to make the $23.0 million Subordinated Loan, to make a $2.0 million capital contribution to Doe Run Cayman and to repay all amounts outstanding under Doe Run's then existing revolving credit facility. Doe Run has budgeted approximately $13.3 million for capital expenditures for fiscal 1998, primarily for replacement and maintenance of operations, and environmental improvements. In addition to ongoing capital investments, Doe Run has expended an average of approximately $59.5 million per year on maintenance from fiscal 1995 through fiscal 1997. As a result of these expenditures and ongoing efforts, Doe Run believes that it operates and will continue to maintain modern and efficient facilities. With respect to Doe Run Peru, in the first quarter 1998, $10.3 million was provided by operating activities and $3.0 million was used in financing activities, and for the period January 1, 1997 to October 23, 1997, $28.1 million was provided by operating activities and $28.6 million was used in financing activities. Historical cash flows from Doe Run Peru's operating and investing activities for the period January 1, 1997 to October 23, 1997 are not necessarily comparable with the historical cash flows for the year ended December 31, 1996 due to the shorter period included in the 1997 period. As a division of Centromin, Doe Run Peru's Predecessor was historically dependent on Centromin for its working capital management and liquidity requirements. As part of the Acquisition, Doe Run Peru will undertake over a ten-year period the Capital Investment Program of approximately $300.0 million, in part to satisfy its Investment Commitment of $120.0 million as set forth in the Subscription Agreement. Doe Run Peru has budgeted approximately 58 $16.0 million for capital expenditures for fiscal 1998, primarily for replacement and maintenance of operations, and environmental improvements. The Company has significant indebtedness outstanding. See "Risk Factors--Substantial Indebtedness." Management believes that cash flow from operations at Doe Run and Doe Run Peru, in addition to availability under the New Revolving Credit Facilities, will be sufficient to provide for the Company's liquidity needs for the foreseeable future. The New Revolving Credit Facilities, as well as the Indenture, contain numerous covenants and prohibitions that impose limitations on the liquidity of the Company, including requirements that Doe Run and Doe Run Peru satisfy certain financial ratios and limitations on the incurrence of additional indebtedness. See "Risk Factors--Restrictions Imposed by Terms of the Company's Indebtedness," "Description of New Revolving Credit Facilities" and "Description of the Notes--Certain Covenants." The ability of the Company to meet its debt service requirements and to comply with such covenants will be dependent upon future operating performance and financial results which will be subject to financial, economic, political, competitive and other factors affecting the Company, many of which are beyond the Company's control. INFLATION AND SEASONALITY In general, the Company's cost of sales and selling, general and administrative expenses are affected by inflation and the effects of inflation may be experienced by the Company in future periods. Management believes, however, that such effects have not been material to Doe Run during the past three years. With respect to Doe Run Peru, its labor costs and selling, general and administrative expenses, are denominated in local currency, whereas substantially all of its net sales are denominated in U.S. dollars. Doe Run's business is somewhat seasonal; typically in excess of 60% of annual lead metal shipments are made in the months of July through December as a result of seasonal demand from battery manufacturers. Doe Run Peru's business is generally not affected by seasonal factors. ENVIRONMENTAL MATTERS The Company has incurred and will continue to incur capital and operating expenditures for matters relating to environmental control and monitoring. Capital expenditures by Doe Run for environmental control and monitoring were $1.8 million, $6.8 million and $7.3 million for the fiscal years 1995, 1996 and 1997, respectively. Due to the pending sale and associated uncertainties, Metaloroya environmental expenditures in 1995, 1996 and 1997 were modest. Doe Run and Doe Run Peru estimate their environmental capital expenditures will be approximately $4.8 million and $2.7 million, respectively, in fiscal 1998, and $3.3 and $3.7, respectively, in fiscal 1999. See "Business--Doe Run--Environmental Matters" and "--Doe Run Peru--Environmental Matters." Doe Run expended on all environmental matters, which includes amounts capitalized, amounts charged to operating expense and amounts charged to reserves, approximately $17.5 million in fiscal 1997, and the Company estimates such expenditures will be $18.0 million and $18.2 million in fiscal 1998 and 1999, respectively. Environmental laws and regulations have changed rapidly in recent years, and the Company may become subject to more stringent environmental laws and regulations in the future. Compliance with more stringent environmental laws and regulations could have a material adverse effect on the Company's consolidated financial position, results of operations and liquidity. The Environmental Protection Agency (the "EPA") has asserted certain alleged environmental violations against Doe Run, which are described in "Business--Doe Run--Environmental Matters." 59 HEDGING ACTIVITIES In the normal course of its business, Doe Run has used in the past and may use in the future forward sales commitments and commodity put and call option contracts to manage its exposure to fluctuations in the prices of lead, copper, zinc and silver. Contract positions are designed to ensure that the Company will receive a defined minimum price for certain quantities of its production. Gains and losses, and the related costs paid or premiums received, for option contracts which hedge the sales prices of commodities are recognized in net sales when the related production is sold. None of the aforementioned activities have been entered into for speculative purposes. Metaloroya, as a government-owned enterprise, did not undertake hedging activities. Doe Run contemplates using hedging activities on behalf of Doe Run Peru in the future consistent with past practices at Doe Run. YEAR 2000 BUSINESS MATTERS Many information and process control systems used in the current business environment were designed to use only two digits in the date field, and thus may not function properly in the year 2000. The Company has conducted a comprehensive review of its computer systems to identify the systems that could be affected by the "year 2000 problem" and has implemented a plan to resolve the issues identified. Any of the Company's programs that have date-sensitive software may recognize a date using "00" as the year 1900 rather than the year 2000, which could result in a major system failure or in miscalculation. Currently, most of the major systems of the Company have been modified to be year 2000 compliant. The Company anticipates that the appropriate modifications to all information and process control systems will be completed by the end of 1998. The cost of achieving year 2000 compliance is included in the Company's operating and administrative expenses. The Company does not currently expect year 2000 issues to have any material effect the Company's costs or to cause any significant disruption in operations. 60 INDUSTRY Doe Run's principal product is refined lead, and Doe Run Peru's principal products include base metals, copper, lead and zinc, and precious metals, silver and gold. Market prices for these metals tend to be cyclical and reflect a combination of factors, including prevailing economic conditions, market demand, prevailing trends of inventory levels and, to a lesser extent, inventory carrying costs (primarily interest rates), international exchange rates and the actions of participants in the commodity markets. These factors have been of varying importance in influencing the prevailing metal prices and often have had divergent impacts on such price. Lead, copper, silver, zinc and gold are all publicly traded on one or more commodity exchanges, including the LME. The LME provides an efficient and orderly market on which to trade non-ferrous metals. The market provides reference prices for worldwide pricing of activities relating to non-ferrous metals, and it provides storage facilities to enable market participants to make or take physical delivery of approved brands of metals. Summarized below is a general overview of the lead, copper, zinc and silver markets. LEAD Lead is a versatile metal used in both its pure form and in alloys, due to its electrochemical characteristics, density, malleability and corrosion resistance. Primary uses for refined lead include lead-acid batteries, lead pigments and compounds, rolled and extruded products, cable sheathing and ammunition. Similar to other base metals, lead prices fluctuate generally based on world supply and demand. Western world consumption of lead for 1997 was estimated at 5.8 million tons, which represents a total market of approximately $3.2 billion. The following table sets forth western world lead consumption by end use for the period 1960 through 1997: WESTERN WORLD LEAD CONSUMPTION BY END USE

Lead demand has increased consistently at a CAGR of approximately 2.4% for the period 1960 to 1997 and approximately 2.0% for the period 1987 to 1997, growing 0.75% from 1996 to 1997, driven primarily by demand for lead-acid batteries. Approximately 4.2 million tons, or 72%, of the lead consumed in 1997 was used in the production of lead-acid batteries, 75% of which was for SLI batteries. Approximately 83% of SLI battery sales are in the automotive replacement market, a market with stable demand characteristics, which is dependent upon the number of automobiles in service and battery life. Lead pigments and compounds are the second largest use of lead and include such end uses as computer and television screens, leaded glass and crystal and printed circuit boards. Uses of rolled and extruded lead products include lead anode plates used in the production of refined copper, radiation shielding for health care applications and roof flashings construction applications. Historically, lead has also been used as an additive in gasoline to reduce engine knock and for insulation of underground cables. 61 Environmental concerns arising in the early 1980s, however, caused a significant reduction in the amount of lead utilized for gasoline, and technical considerations have reduced usage of lead in cable sheathings. The western world supply of refined lead is dependent upon the availability of lead ore, the principal raw material for primary smelters, secondary sources and net exports of lead from non-western world countries, such as the former Soviet Union and China. The following table summarizes western world refined lead supply for the period 1988 to 1997: WESTERN WORLD REFINED LEAD SUPPLY

Since 1991, primary lead production has remained relatively constant. Management believes that due to capital costs and environmental concerns, no new primary smelting capacity will be added in the world in the foreseeable future. As a result, primary production is expected to remain relatively constant, with any increase resulting from operational improvements at existing facilities. Refined lead supply is also affected by the availability of lead ore which is the principal raw material for primary production facilities throughout the world. The following table summarizes western world lead mine production for the period 1988 to 1997: WESTERN WORLD LEAD MINE PRODUCTION

Although primary production has remained relatively constant, lead production from secondary sources has increased, driven primarily by the greater availability of spent lead-acid batteries and other lead-bearing materials. Due to heightened environmental awareness, stockpiling of lead-bearing materials such as batteries became economically unviable during the early 1990s. As a result, battery manufacturers established outlets for spent batteries returned in connection with replacement battery sales, which has resulted in the development of secondary facilities throughout the world. By 1997, approximately 3.0 million tons of lead were being converted from secondary materials. Secondary processing of lead results in approximately 98% recovery of lead from the lead-bearing materials. Battery manufacturers have increasingly integrated their operations into the secondary market in addition to purchasing primary and secondary lead from third parties such as Doe Run. Management estimates that the secondary supply of lead will continue to increase in the foreseeable future, as the availability of spent lead-acid batteries and 62 other lead bearing materials requiring recycling increases. This trend is expected to result in a more predictable pattern of lead supply. Lead supply in the western world is also impacted by net exports of lead from Eastern Europe, the former Soviet Union and China. Prior to 1990, these regions were net importers of refined lead. In the early 1990s, these regions experienced adverse economic conditions and consequently began exporting lead and other metals to build hard currency reserves. Since 1994, exports from Eastern Europe and the former Soviet Union have declined, which management believes reflects both a reduction in inventories and production capabilities resulting from the closure of inefficient facilities. Increased exports from China have more than offset this reduction, resulting in an increase of net exports to the western world in 1996. Preliminary industry data for 1997 indicates that net exports from China declined 30.0%, whereas consumption increased 5.6%. The price of refined lead in the western world reflects a combination of factors including prevailing economic conditions, lead demand and the availability of refined lead in the market. Lead prices are also affected by international trade with non-western world producers that export lead into the western world. The following table sets forth the average LME prices for lead during each of the years 1988 to 1997.
1988 1989 1990 1991 1992 1993 1994 1995 --------- --------- --------- --------- --------- --------- --------- --------- LME Prices (per pound)..................... $ .30 $ .31 $ .37 $ .25 $ .24 $ .18 $ .25 $ .29 1996 1997 --------- --------- LME Prices (per pound)..................... $ .35 $ .28
The LME price for lead as of March 31, 1998 was $.26 per pound. Management attributes the decline from 1997 levels to a general slowdown in replacement battery sales resulting from more moderate weather conditions in late 1996 and early 1997 in North America and Europe. COPPER Copper ranks second to aluminum as the most widely used non-ferrous metal in the world. Recognized for its metallurgical and physical properties, including high electrical and thermal conductivity, corrosion resistance, ductility, malleability and strength, copper is a versatile metal, used in its pure form and in alloys in a variety of industrial markets. These markets include construction, electrical and electronic parts, industrial machinery and equipment, transportation and consumer products. From 1987 to 1997, western world copper demand grew at a CAGR of approximately 3.3%, during which time copper prices averaged $1.08 per pound. In 1997, western world copper consumption was estimated at 12.3 million tons, a record level for the twelfth consecutive year, which represents a total market of $25.3 billion. The following table sets forth the average LME prices for copper during each of the years 1988 to 1997.
1988 1989 1990 1991 1992 1993 1994 1995 --------- --------- --------- --------- --------- --------- --------- --------- LME Prices (per pound)..................... $ 1.18 $ 1.29 $ 1.21 $ 1.06 $ 1.04 $ .87 $ 1.05 $ 1.33 1996 1997 --------- --------- LME Prices (per pound)..................... $ 1.04 $ 1.03
The LME price for copper as of March 31, 1998 was $.79 per pound. Management attributes the decline from 1997 levels to a general increase in metal inventories following higher production levels against softening demand in Asia. ZINC Zinc is the third most widely used non-ferrous metals in the world, with annual consumption exceeded only by aluminum and copper. Zinc is principally used as an anti-corrosive coating to produce galvanized steel, which ultimately is consumed in the automotive and construction industries. The galvanizing of steel sheet and strip accounts for approximately 50% of annual zinc consumption and is the largest growth sector for zinc. Other uses for zinc include alloys, such as brass, used in a variety of consumer products and zinc-aluminum used in the production of pressure die cast parts. From 1987 to 1997, western world zinc 63 demand grew at a CAGR of approximately 2.4%, during which time zinc prices averaged $.53 per pound. In 1997, western world zinc consumption was estimated at 7.0 million tons, which represents a total market of $8.4 billion. The following table sets forth the average LME prices for zinc during each of the years 1988 to 1997.
1988 1989 1990 1991 1992 1993 1994 1995 --------- --------- --------- --------- --------- --------- --------- --------- LME Prices (per pound)..................... $ .56 $ .78 $ .69 $ .51 $ .56 $ .44 $ .45 $ .47 1996 1997 --------- --------- LME Prices (per pound)..................... $ .47 $ .60
The LME price for zinc as of March 31, 1998 was $.50 per pound. Management attributes the decline from 1997 levels to an increase in the availability of zinc concentrates in the market. SILVER Silver historically has been used principally in coinage, reflecting its monetary value as a precious metal. Presently, however, demand for silver is predominately commercial, with uses in photography, electrical and electronic products, tableware, jewelry, medicine and dentistry. Industrial demand, which accounts for approximately 98% of total silver demand, increased 5.5% in 1997 to 799 million ounces, which represents a total market of $3.9 billion. From 1987 to 1996, western world silver demand grew at a CAGR of approximately 4.8%, during which time silver prices averaged $5.19 per ounce. The following table sets forth the average LBMA prices for silver during each of the years 1988 to 1997.
1988 1989 1990 1991 1992 1993 1994 1995 --------- --------- --------- --------- --------- --------- --------- --------- LBMA Prices (per ounce).................... $ 6.53 $ 5.50 $ 4.83 $ 4.05 $ 3.95 $ 4.30 $ 5.28 $ 5.20 1996 1997 --------- --------- LBMA Prices (per ounce).................... $ 5.20 $ 4.90
The LBMA silver price as of March 31, 1998 was $6.33 per ounce. Management believes that increases for 1997 reflects an imbalance between supply and demand for silver, with the demand for silver for commercial applications exceeding the available supply from producers. 64 BUSINESS GENERAL Doe Run is the largest fully-integrated lead producer in North America and the second largest primary lead producer in the western world. Through its subsidiary Doe Run Peru, Doe Run operates one of the largest polymetallic processing companies in the world offering an extensive product mix of non- ferrous and precious metals, including copper, silver, zinc, lead and gold. The combined capabilities of Doe Run and Doe Run Peru represent the largest primary lead producer in the western world. On October 23, 1997, Doe Run Peru acquired Metaloroya from Centromin, a Peruvian government-owned conglomerate, as part of the ongoing privatization program sponsored by the government of Peru. On December 30, 1997, Metaloroya was merged into Doe Run Peru. The Company had pro forma net sales and EBITDA of $709.8 million and $74.5 million, respectively, for the twelve months ended October 31, 1997 and net sales and EBITDA of $169.1 million and $17.7 million, respectively, for the three months ended January 31, 1998. DOE RUN Doe Run's integrated operations permit Doe Run to participate in and manage the entire lead life cycle, including the mining of lead ore, the production of refined lead metal, the fabrication of value-added lead products and the secondary recycling of spent lead-acid batteries and other lead-bearing materials. Doe Run believes its reputation for excellent service, product quality and timely delivery permits it to consistently realize premiums for its products, resulting in sales prices above the market price for lead quoted on the LME. In fiscal 1997, Doe Run shipped approximately 350,000 tons of refined lead metal and lead alloy products, including recycled lead, representing approximately 19% of North American consumption and 6% of western world consumption. Doe Run had net sales and EBITDA of $277.9 million and $31.9 million, respectively, for fiscal 1997, excluding the results of operations of Doe Run Peru for the eight-day period from October 23, 1997 (the date of consummation of the Acquisition) through October 31, 1997 and net sales and EBITDA of $59.8 million and $1.7 million, respectively, for the three months ended January 31, 1998. Refined lead product sales accounted for approximately 67% and 68% of Doe Run's total net sales, or $185.1 million and $41.0 million, respectively, in fiscal 1997 and for the three months ended January 31, 1998, respectively. The balance of Doe Run's net sales resulted from (i) tolling services provided to major U.S. lead-acid battery manufacturers, (ii) lead production by-products, including zinc and copper concentrates, and (iii) value-added fabricated lead products, such as lead sheet and bricks. These net sales from tolling services, by-products and fabricated products provide sources of revenue largely independent of lead prices. Western world lead consumption in 1997 was estimated at 5.8 million tons which represents a total market of approximately $3.2 billion. Approximately 4.2 million tons, or 72%, of this lead was used in the production of lead-acid batteries, approximately 75% of which was for SLI batteries. Approximately 83% of SLI battery sales are in the automotive replacement market, a market with stable demand characteristics, which is dependent upon the number of automobiles in service and battery life. Doe Run's customers include six of the seven largest lead-acid battery manufacturers in the world. The lead-acid battery remains the most cost competitive battery technology for SLI batteries, which management believes will not change in the foreseeable future. Other uses for refined lead include computer and television screens, ammunition, stationary batteries used as backup power sources and rolled and extruded lead products used in radiation shielding and roofing materials. 65 The market for refined lead continues to grow primarily as a result of increasing demand for lead-acid batteries used for automobiles and other vehicles as a result of worldwide economic growth. As a result, western world lead consumption grew at a CAGR of 2.0% between 1987 and 1997, growing 0.75% from 1996 to 1997. Doe Run believes that this growth rate will accelerate in the future as batteries become an even larger portion of the lead market, particularly in light of expected economic growth leading to increased vehicle population in developing economies. Approximately 45% of annual worldwide lead consumption is supplied from newly mined or "primary" ore, and the balance is supplied from secondary sources, principally the recycling of spent lead-acid batteries and other lead-bearing materials. Since 1990, primarily due to heightened environmental awareness, secondary lead capacity has increased, whereas primary lead capacity has remained relatively constant. Management believes that secondary sources of lead will continue to account for an increasing share of the total worldwide lead market. The average LME price for refined lead was $.29 per pound in fiscal 1997. As of March 31, 1998, the LME price for lead was $.26 per pound, which was below the ten-year average price of $.28 per pound. Management believes that lead prices will remain relatively stable or will modestly increase for the remainder of fiscal 1998 and over the long term will reflect the historical industry average. As a result of the recent lead price decreases, the Company expects that it will incur an operating loss in its U.S. operations that will adversely affect its EBITDA in fiscal 1998. Doe Run conducts its mining operations along approximately 40 miles of the Viburnum Trend in Southeastern Missouri, one of the world's most productive lead deposits. Doe Run operates six production shafts, four processing mills, one primary smelter and one secondary smelter. During fiscal 1997, Doe Run mined in excess of 5.0 million tons of ore containing average grades of 5.17% lead, 1.02% zinc and 0.27% copper. At the end of fiscal 1997, Doe Run's proven and probable reserves consisted of approximately 70 million tons, containing approximately 3.8 million tons of recoverable lead or approximately fourteen years of production at current mining rates. Doe Run's primary smelter in Herculaneum, Missouri is the largest in North America and the second largest in the world, with an annual production capacity of approximately 250,000 tons of refined lead. Since entering the recycling business in 1992, Doe Run has become a leading producer of secondary lead at its Buick recycling facility and secondary smelter located in Boss, Missouri. At this facility, Doe Run is reclaiming at a rate of approximately 105,000 tons of refined lead per year, approximately 60% of which is derived from tolling arrangements with major U.S. battery manufacturers. DOE RUN PERU Doe Run Peru's unique combination of base metal smelters, refineries and by-product circuits enable Doe Run Peru to process complex polymetallic concentrates and to recover base metals and by-products at international quality standards. Doe Run Peru's location in central Peru, approximately 110 miles from Lima, allows Doe Run Peru to source concentrates advantageously from mines located throughout the central Andes mountains, particularly in Peru. Moreover, Doe Run Peru's proximity to Lima's Callao port provides it ready access to major world markets for its products. For the twelve months ended October 31, 1997 and the three months end January 31, 1998 Doe Run Peru shipped approximately 70,000 tons and 18,000 tons, respectively, of refined copper, 107,000 tons and 27,000 tons, respectively, of refined lead, 71,000 tons and 18,000 tons, respectively, of refined zinc, 20.5 million ounces and 6.5 million ounces, respectively, of refined silver and 42,000 ounces and 13,000 ounces, respectively, of gold bullion. In addition, Doe Run Peru shipped various by-products including bismuth, indium, tellurium, antimony, cadmium and copper blister. Doe Run Peru had net sales and Adjusted EBITDA of $431.9 million and $50.7 million, respectively, for the twelve months ended October 31, 1997, including the period from October 23, 1997 through October 31, 1997, and net sales and 66 EBITDA (excluding intercompany transactions) of $109.2 million and $16.0 million, respectively, for the three months ended January 31, 1998. Of Doe Run Peru's net sales, refined copper, silver, zinc, lead and gold accounted for 35%, 23%, 19%, 15% and 3%, respectively, for the twelve months ended October 31, 1997, and 26%, 32%, 18%, 13% and 3%, respectively, for the three months ended January 31, 1998, with the balance of net sales derived from sales of various by-products. For the twelve months ended December 31, 1996, Doe Run Peru was Peru's second largest exporter, exporting approximately 80% of its total shipments to North America, Europe and Asia, as well as other Latin American countries. Doe Run Peru's customers include end-users of base metals and metal by-products, as well as international metal trading companies. Doe Run Peru's operations consist of smelting and refining complex concentrates that it purchases from unaffiliated mining operations. Doe Run Peru typically purchases concentrate feedstock pursuant to annual contracts at a price based on a percentage of the payable base metal and precious metal content of the concentrates. The price is reduced by processing fees or treatment charges to refine the concentrates, as well as by penalties charged to remove impurities within the concentrates, such as arsenic, antimony and bismuth. Base metal prices, treatment charges and penalties are generally established based upon prevailing market conditions by reference to prices in the world market, including on the LME. Currently, Doe Run Peru has entered into supply contracts, primarily with one-year terms, that meet approximately 95% of its concentrate requirements for fiscal 1998. Doe Run Peru pays concentrate suppliers for the majority of the metal content of the concentrates purchased and, thus, derives its operating profit primarily from treatment charges and penalties. In addition, Doe Run Peru generates operating profit from the sale of by-products, as well as from metals sold at a premium to the price paid for such metal. Moreover, since Doe Run Peru's metallurgical recoveries are typically in excess of the paid metal percentages, Doe Run Peru further increases its operating profit from the sale of the metal produced from such recoveries. The markets for Doe Run Peru's products are global and continue to grow as a result of worldwide economic growth. Given the diversity of its products and by-products, Doe Run Peru's financial performance is not solely dependent upon the prospects for any one of its products or by-products. Moreover, since Doe Run Peru is a processor of complex concentrates and does not presently own any mines from which it sources concentrates, Doe Run Peru's financial performance is less sensitive to the volatility of base metal prices. COMPETITIVE STRENGTHS The Company believes that its competitive strengths include the following: FOCUSED BUSINESS STRATEGY The production of lead and related products is Doe Run's primary business, whereas lead generally represents a small percentage of its competitors' overall operations. As a result, Doe Run believes that its ability to quickly recognize and respond to various trends that affect the lead industry and its customers provide Doe Run with a preferred status with its customers. This responsiveness, along with its reputation for excellent service, product quality and timely delivery, permits Doe Run to consistently realize premiums for its products, resulting in sales prices above the market price for lead quoted on the LME. With the assistance and direction provided by Doe Run, Doe Run Peru, as a private enterprise, is well positioned to recognize and respond to various trends that affect the smelting and refining industry, as well as its customers. Doe Run Peru will implement its business strategy with the operating flexibility to (i) make discretionary capital expenditures and (ii) purchase an optimum mix of concentrate feedstock from a wider range of suppliers than it could under the constraints that existed as a government-owned enterprise. 67 DIVERSE PROCESSING CAPABILITIES The combination of Doe Run's and Doe Run Peru's processing capabilities provides the Company greater diversity in its net sales and EBITDA. Specifically, with the Acquisition, approximately 74% and 75% of the Company's net sales for the twelve months ended October 31, 1997 and the three months ended January 31, 1998, respectively, were derived from (i) the treatment and processing of base metal concentrates, including copper, silver, zinc, lead and gold, (ii) the fabrication of lead and lead related products, (iii) the tolling of spent lead-acid batteries for major U.S. lead-acid battery manufacturers and (iv) the sale of zinc and copper concentrates. Such value-added tolling and other products and services are less sensitive to base metal price fluctuations. FAVORABLE ACCESS TO RAW MATERIALS Peru and its neighboring Latin American countries, primarily Bolivia, are significant producers of complex concentrates that contain multiple metals and high levels of impurities. Doe Run Peru obtains substantially all of its lead and zinc concentrates and approximately 80% of its copper concentrates from Peruvian sources. Since Doe Run Peru operates one of the few complex concentrate processing facilities in the world, Doe Run Peru obtains favorable pricing terms from its concentrate suppliers due to the complex nature of the concentrates and its proximity to the producing mines. As a result, Doe Run Peru believes that it operates at a geographic competitive advantage to comparable facilities located farther from their sources of complex concentrates. Currently, Doe Run Peru has entered into supply contracts, primarily with one-year terms, that meet approximately 95% of its concentrate requirements for fiscal 1998. FLEXIBLE MINING OPERATIONS Due to its extensive polymetallic ore resources, Doe Run has flexibility in developing its mining and milling plans to take advantage of prevailing market conditions for lead, zinc and copper. Depending on lead, zinc and copper prices, Doe Run has the ability, to a certain extent, to optimize its mine production by targeting certain ore grades in order to enhance operating margins. By maintaining such flexibility, Doe Run is able to reduce its exposure to metal price volatility. U.S. DOLLAR-BASED REVENUES The mining industry in which Doe Run Peru is a major participant is Peru's largest export industry, representing approximately 45% of Peru's total export sales in 1997. For the twelve months ended October 31, 1997 and the three months ended January 31, 1998, exports accounted for 78% and 77%, respectively, of Doe Run Peru's shipments and more than 79% and 72%, respectively, of its net sales. In addition, substantially all of Doe Run Peru's net sales are denominated in U.S. dollars. As a result, Doe Run Peru's net sales is less sensitive to foreign currency fluctuations. EXPERIENCED MANAGEMENT AND LABOR FORCE Doe Run's management team has extensive experience in the mining and metals production industry with an average of 23 years in the industry. The extensive experience of the Doe Run management team complements the skills of Doe Run Peru's executive personnel to provide Doe Run Peru with the strong management team necessary to compete as a private enterprise in the world markets. In addition, the Company employs a highly skilled workforce whose average tenure with the Company is more than 20 years. HIGH BARRIERS TO ENTRY Management believes that the capital costs and environmental requirements associated with constructing facilities comparable to those of the Company result in high barriers to entry for prospective entrants. Management estimates that it would cost approximately $700 million to establish mining, milling 68 and smelting operations with the production capacity and efficiency of Doe Run. Moreover, management is not aware of any significant mineral deposit in North America with lead grades and reserves similar to that of the Viburnum Trend. With respect to Doe Run Peru, management estimates that it would cost approximately $950 million to establish smelting and refining operations with the production capacity and efficiency of Doe Run Peru. Management believes that the cost and time commitment required to achieve commercial production for any new mining, milling, smelting or processing operation, including regulatory approvals, heightens the barriers to entry. BUSINESS STRATEGY The Company's business strategy is to improve its operations and financial performance by focusing on the following principal elements: INCREASE CAPACITY AND IMPROVE OPERATING EFFICIENCIES Doe Run is committed to improving its operating efficiencies through focused capital investments that increase capacity utilization, enhance productivity and lower costs. Since the acquisition of Doe Run by Renco in April 1994, Doe Run has completed approximately $34.4 million of capital investments through January 31, 1998 designed in part to reduce production costs and improve product quality. Additionally, Doe Run seeks to identify non-capital cost reduction opportunities throughout its operations. Doe Run has increased its primary lead production capacity from the original annual capacity of 225,000 tons to approximately 250,000 tons presently with minimal capital investment. In addition, Doe Run has increased its secondary lead production capacity from the original annual capacity of 60,000 tons to approximately 105,000 tons presently with minimal capital investment. The Company has identified a number of strategic initiatives designed to improve Doe Run Peru's operating efficiencies and its competitive position within the industry through focused capital investment. In furtherance of this strategy, Doe Run Peru has adopted a ten-year Capital Investment Program of approximately $300.0 million in an effort to enhance various elements of Doe Run Peru's operations. The Capital Investment Program will target specific areas of Doe Run Peru's facilities, such as the copper and lead circuits, to improve product quality, increase capacity, improve productivity and reduce costs in the targeted area, thereby enhancing Doe Run Peru's net sales and EBITDA. In addition, the Capital Investment Program is designed to help achieve compliance with applicable environmental standards in Peru. MAINTAIN AND BUILD STRONG RELATIONSHIPS WITH STRATEGIC CUSTOMERS Through its ongoing research and development efforts and customer service initiatives, Doe Run strives to build and maintain strong relationships with its customers. Since lead is Doe Run's principal business, Doe Run sales and technical professionals are dedicated to working closely with Doe Run's customers to be responsive to their needs, such as small order quantities, specialized shapes, sizes and alloys, technical assistance and flexible deliveries. As a private enterprise, Doe Run Peru is implementing many of the successful customer service initiatives utilized by Doe Run to build and maintain strong relationships with its customers. Such initiatives will include ongoing research and development efforts, technical assistance and other customer service practices that will encourage a close working relationship with Doe Run Peru's customers. In addition, Doe Run Peru is shifting the focus of its marketing efforts to end users of its products from international trading companies. OPTIMIZE CONCENTRATE SUPPLY AT DOE RUN PERU As a private enterprise, Doe Run Peru is endeavoring to optimize the mix of complex concentrates from a wider range of suppliers than it purchased as a government-owned enterprise. Historically, Doe 69 Run Peru obtained the vast majority of its concentrate requirements from Centromin mines, typically pursuant to annual contracts. Given Doe Run Peru's unique position as one of the few processing facilities in the world for complex concentrates, Doe Run Peru will source its raw materials on a competitive basis within Peru from both Centromin mines and private mines, as well as from other Latin American suppliers. Currently, Doe Run Peru has entered into supply contracts, primarily with one-year terms, that meet approximately 95% of its concentrate requirements for fiscal 1998. GROW DOE RUN'S CORE LEAD BUSINESS Doe Run seeks to increase sales and operating cash flow through the growth of its core lead operations. Such efforts include increased sales of refined lead resulting from the expansion of its primary lead production capacity. In addition, Doe Run strives to expand its product offerings of value-added fabricated products including various shapes, sizes and alloys. Margins on fabricated products are relatively insensitive to lead price fluctuations because such fluctuations are generally reflected in the price of the end product. Doe Run is also growing its recycling and related tolling business with U.S. lead-acid battery manufacturers pursuant to contractual agreements under which recycled lead is returned to the supplier in exchange for a processing fee. Such processing fee is generally independent of lead prices. BROADEN REVENUE SOURCES THROUGH STRATEGIC ACQUISITIONS The Company seeks to broaden its revenue sources through the acquisition of related resource assets or businesses that capitalize on the combined experience of Doe Run and Doe Run Peru in mining, milling, smelting and refining base and precious metals. With respect to Doe Run, such opportunities, domestic or international, could be operations in primary or secondary lead production, lead fabrication or non-lead resource businesses. With respect to Doe Run Peru, such opportunities could include the acquisition of mining assets in Peru or other Latin American countries, including, without limitation, those presently undergoing privatization in Peru. The Acquisition reflects the Company's business strategy of broadening its revenue sources through a strategic acquisition, focusing on treatment and processing of base metal concentrates, as well as other metal related services. In particular, Doe Run Peru represented a unique opportunity for Doe Run to capitalize on Doe Run's extensive experience in efficiently managing mature smelter operations. Through the focused investment of capital and the implementation of Doe Run's operating practices, Doe Run Peru believes that it will increase its refined metals capacities and improve product quality, thereby enhancing financial performance through increased revenues and EBITDA. In April 1998, Doe Run entered into a letter of intent with ASARCO to purchase certain assets relating to ASARCO's lead business in Missouri, including a smelter and refinery and two mines. The anticipated purchase price for these assets is approximately $50.0 million, plus contingent deferred purchase price payments over a period not to exceed five years in an aggregate amount not to exceed $12.5 million. This transaction is subject to satisfactory completion of Doe Run's due diligence review and negotiation of a definitive agreement, as well as obtaining certain governmental and third party approvals. Doe Run has only recently commenced its due diligence review and currently cannot assess the likelihood that this transaction will be consummated. Accordingly, there can be no assurance that a definitive agreement related to this transaction will be entered into or that the required governmental approvals will be obtained. DOE RUN PRODUCTS AND SERVICES Doe Run's principal products include refined lead from primary and secondary sources, fabricated products, zinc and copper concentrates and other by-products. In addition, Doe Run provides tolling 70 services where it receives a processing fee for recycling spent lead-acid batteries and other lead-bearing materials. The following table sets forth net sales for each of Doe Run's products and services:

PRIMARY LEAD Doe Run produces high quality refined lead products at its primary Herculaneum smelter, including 99.99% pure lead, the purest commercial lead available. Doe Run also provides a wide variety of product shapes and sizes, as well as a complete series of lead alloys to meet the specialty demands of its customers. Primary lead is used in automotive batteries, computer and television screens, forklift, marine and golfcart batteries, stationary batteries used as backup power sources, as well as rolled and extruded lead products in radiation shielding and roofing materials. High purity lead is required for newer high technology batteries, and is preferred by battery manufacturers for lead oxide, the electrically active component of lead-acid batteries. Doe Run's lead alloy products are used in the manufacture of numerous fabricated products, as well as for ammunition. SECONDARY LEAD Doe Run produces secondary lead at its recycling facility located in Boss, Missouri, where it recycles spent lead-acid batteries and other lead-bearing materials. Of Doe Run's secondary lead production, approximately 60% is derived from tolling arrangements with battery manufacturers. Under such multi-year arrangements, manufacturers send spent batteries to Doe Run, which recovers the lead and returns it to the battery manufacturer for a processing fee. As part of such arrangements, Doe Run offers its tolling customers the opportunity to purchase or receive primary lead or lead alloys in exchange for their spent lead-acid batteries at specified economic terms. Due to the terms of these arrangements, Doe Run's operating profits from this service are largely unaffected by lead price fluctuations. In addition to revenues resulting from tolling services, Doe Run directly sells secondary lead and recycles other lead-bearing materials for which it receives processing fees. FABRICATED LEAD PRODUCTS Doe Run processes lead metal into custom products such as: lead oxide, the key ingredient in lead-acid batteries; lead anode plates used in copper refining; x-ray and radiation shields for the medical profession; roof flashings for the construction industry; and lead for ammunition. Doe Run also installs radiation shielding in hospitals and cancer treatment centers and installs and maintains lead-lined storage tanks and pollution control devices for the chemical, petroleum and smelting industries. Margins on Doe Run's sales of value-added products are relatively insensitive to lead price fluctuations, as Doe Run generally is able to reflect such fluctuations in the price of the end product. 71 ZINC CONCENTRATES Doe Run mines zinc as a by-product of its lead-mining operations. Zinc concentrates are sold on the open market or to zinc smelters. In fiscal 1997, Doe Run produced approximately 70,000 tons of zinc concentrates, with an average metal content of 59.6% zinc. COPPER CONCENTRATES Doe Run mines copper as a by-product of its lead operations. Copper concentrates are sold on the open market or to copper smelters. In fiscal 1997, Doe Run produced approximately 27,000 tons of copper concentrates, with an average metal content of 29.1% copper. OTHER PRODUCTS AND SERVICES Doe Run produces various other by-products resulting from the production of lead. Such products include sulfuric acid which is sold to fertilizer manufacturers, as well as primary and secondary furnace drosses, which are sold to custom smelters for further recovery of various minerals. The secondary facility also sells polypropylene and sodium sulfate and provides other services, including stripping of lead-sheathed cable and recycling of various hazardous materials. MARKETING AND SALES Doe Run's marketing and sales strategy is to maximize the net realized selling prices for its products. In furtherance of this strategy, Doe Run provides its customers small order quantities, specialized shapes, sizes and alloys, technical assistance and flexible deliveries. Doe Run generally sells lead on a delivered basis with freight charges included. Doe Run's central U.S. location allows it to have transportation costs significantly lower than its major competitors with operations outside of North America. Moreover, due to its location, Doe Run is able to provide its customers just-in-time delivery at a lower cost than most of its competitors. Doe Run is actively involved with several customers in developing new uses for lead. Such uses include lead foil for advanced lead-acid batteries, low radiation lead solder for printed circuit boards and superior lead alloys for optimizing battery performance. Zinc and copper concentrates generally are sold to North American smelters pursuant to multi-year (typically three year) contracts awarded under a bid process. Due to Doe Run's geographic location, transportation costs for its zinc and copper concentrates are low relative to its competitors' costs. Similar to lead, transportation costs are a significant factor in selling concentrates. Doe Run's sales of lead metal, concentrates and by-products are handled by Doe Run's staff of direct sales people assisted by customer service representatives. Technical assistance is provided by plant operating personnel. CUSTOMERS Doe Run had approximately 160 lead metal customers in fiscal 1997, of which the five largest accounted for approximately 41% of Doe Run's lead metal net sales. Approximately 70% of Doe Run's lead sales were pursuant to contractual agreements, typically one year or less. Such contracts generally set forth minimum volume and pricing terms. Exports represented approximately 7% of Doe Run's net sales in fiscal 1997. 72 Doe Run's customers include six of the seven largest lead-acid battery manufacturers in the world. JCI purchased lead and tolling services representing approximately 12% of Doe Run's fiscal 1997 net sales. In addition, Big River purchased zinc concentrates, which represented approximately 10% of Doe Run's net sales in fiscal 1997. COMPETITION Doe Run is the largest fully-integrated lead producer in North America and the second largest primary lead producer in the western world. The leading producer of lead in the world is Quexco Incorporated ("Quexco"), with operations in Europe, as well as North America where Quexco operates secondary operations under the name of RSR Corporation ("RSR"). Metaleurop S.A. is a significant European producer of both primary and secondary lead. In North America, Doe Run's principal competitors in primary lead include Cominco Ltd., ASARCO, Noranda Inc. and Industrias Penoles S.A. In secondary recycling of lead, Doe Run competes with Exide, which is also a customer of Doe Run, GNB Inc., RSR and several other smaller industry participants. PRODUCTION PROCESS Doe Run produces refined lead metal from its primary processing facility, as well as through its secondary recycling operations. Summarized below is a description of the production process for primary and secondary lead production. PRIMARY The production of lead involves three major stages: mining, milling and smelting. MINING AND MILLING. Doe Run operates six production shafts and four processing mills, including one mill presently maintained on a stand-by basis. Doe Run's polymetallic ore bodies are mined using the "room and pillar" method. With this method, ore is removed by blasting in a manner that leaves pillars to support the rooms created by the removed ore. Mining involves drilling and blasting limestone rock 500 to 1,000 feet below the earth's surface. The ore is hauled by large, diesel-powered equipment before being hoisted above ground to the mill. During fiscal 1997, Doe Run's mining operations produced in excess of 5.0 million tons of ore, containing average grades of 5.17% lead, 1.02% zinc and 0.27% copper. The milling process includes further crushing and grinding, subsequent to which the ore is treated in a flotation process to separate and concentrate the minerals. The milling process recovers payable minerals from the ore. The remaining materials, or tailings, are sent to settling ponds near the mill sites, which are operated and maintained to ensure groundwater purity. The final products are lead, zinc and copper concentrates that are shipped off-site for smelting. The lead concentrates are shipped to the Herculaneum smelter, while zinc and copper concentrates are marketed to other firms. SMELTING. Located on the Mississippi River, south of St. Louis, the Herculaneum smelter is the largest lead smelter in North America and the second largest in the world. The smelter commenced operations in 1892 and has been in continuous operation since that time, processing lead concentrates from Doe Run's mining and milling operations. The smelter has a capacity of 250,000 tons per year and utilizes a pyrometallurgical process to produce 99.99% refined lead. The annual capacity of the smelter was recently upgraded to approximately 250,000 tons following the introduction of certain process control improvements at the blast furnace and other plant modifications. Doe Run is in the process of further increasing the capacity to approximately 270,000 tons per year. Doe Run recently completed construction of a $7.2 million 550-foot tall emissions stack that has allowed 73 production capacity to increase at its primary smelter and improved the facility's environmental performance. Consistent with Doe Run's commitment to product quality and customer service, in January 1998, Doe Run's Herculaneum facility obtained ISO 9002 certification, an internationally recognized quality system standard. SECONDARY Located in Boss, Missouri, Doe Run's recycling facility processes spent lead-acid batteries and other lead-bearing materials. The facility is a Resource Conservation Recovery Act approved site. The facility employs a sophisticated monitoring system to prevent leaks from penetrating the surrounding environment. In fiscal 1997, the facility reclaimed approximately 105,000 tons of refined lead. Approximately 60% of this total results from tolling contracts, while 53% of the total supply resulted from automobile batteries. Production capacity has been increased to approximately 110,000 tons currently from the original capacity of 60,000 tons with minimal capital investment. At Doe Run's recycling facility, whole batteries are dismantled in a hammer mill, and the components are recovered by a combination of screening and gravity separation in water columns. Grids and posts are collected in a bin, polypropylene is loaded into trucks and lead paste is separated for further treatment. Grids and posts are melted in a rotary furnace to produce antimonial lead alloys. The paste is processed in a reverberatory furnace to produce pure lead and a high antimony slag which is further processed in a blast furnace to recover additional lead, antimony and tin. The remaining slag is disposed of as a non-hazardous material at a licensed facility. Management believes this recycling facility generates two-thirds less waste than traditional battery recycling facilities. Consistent with Doe Run's commitment to product quality and customer service, in April 1997, Doe Run's recycling facility obtained ISO 9002 certification. MINING OPERATIONS GEOLOGY Doe Run's operations are centered around the ore-rich Viburnum Trend in Southeastern Missouri. Approximately 500 million years ago, the Precambrian core of the St. Francois Mountains formed a group of islands. The water around these islands was shallow, and algae formed a reef around them. Over time, the islands and the reef were covered by sea water and layers of sediment. These layers eventually hardened into rock. Mineral-bearing fluids flowed through the rock, depositing substantial amounts of lead, zinc and copper near and in the reef. Portions of this reef and surrounding areas contain valuable mineral deposits now known as the Viburnum Trend. Doe Run's Viburnum Trend ore body is predominantly in the Bonne Terre geologic formation, which is dolomitic limestone. The principal metallic constituents are lead, zinc and copper, with trace amounts of silver. The ore body being mined is an irregular mass of sulfide ores, principally lead, zinc and copper sulfides, approximately 1,000 feet in depth and with varying widths of up to 2,000 feet. PRODUCTION SHAFTS Doe Run's mining operations utilize six production shafts that form a north-south line along approximately 40 miles of its Viburnum Trend ore body. Three production shafts, Viburnum-28, Viburnum-29 and Viburnum-35, lie within a five-mile radius east, north and south, respectively, of Viburnum, Missouri. The Buick, Brushy Creek and Fletcher production shafts are five miles, sixteen miles and twenty miles, respectively, south of Viburnum, Missouri. All of Doe Run's mining and milling facilities are 74 accessible by state or county roads or Company-owned haul roads. Products are shipped by truck over public roads or by rail, with rail loading capabilities at two of Doe Run's mining facilities. Five of the production shafts, Viburnum-28, Viburnum-29, Viburnum-35, Brushy Creek and Fletcher, were developed by predecessors of Doe Run. The sixth production shaft, Buick, was developed and initially operated by a joint venture of Homestake Mining Company and American Metal Climax (the "Homestake Joint Venture") in the 1960s. In 1986, the Buick mining operations became part of Doe Run's Predecessor. Doe Run owns the property where the necessary surface structures for mining and milling are located. The mineral rights are held either by fee title or mineral leases with either private landowners or the federal government. There are numerous mineral exploration leases, most of which are for exploration of new mineral ore deposits. Four of the production leases are private leases, and nine are government leases. The mineral leases with private landowners have no expiration periods. The government leases are for a period of ten years and are renewable. The related mining operations are conducted pursuant to four development contracts, which also are for ten years subject to renewal. The Viburnum, Fletcher, Buick and Brushy Creek development contracts consist of four, two, one and two leases, respectively, which are due for renewal March 31, 2018, May 31, 2003, October 31, 2004 and May 31, 2003, respectively. Doe Run is required to make royalty payments under the leases. The production shafts are approximately 1,000 feet deep, with the exception of Viburnum-28 and Viburnum-29 which are 800 feet and 500 feet deep, respectively. All mining by Doe Run is performed underground on one level by the room and pillar method. Blasting typically is accomplished by using an ammonium nitrate fuel oil mix; however, dynamite is used under wet conditions. Front-end loaders are used to load the blasted ore onto trucks that haul the ore from the production face to the production shaft. Doe Run maintains fleets of trucks, drilling equipment and loading equipment, which generally are rubber-tired and diesel-powered, at each of its production shafts. The equipment is of various ages, and much of the older equipment has been upgraded or rebuilt. Doe Run employs a computerized maintenance scheduling and tracking system that directs and monitors preventive maintenance and repair activities of all equipment. In addition to maintaining its existing equipment, Doe Run has recently acquired or leased new equipment which enhances operating efficiencies, such as low-profile equipment capable of operating in ten-foot openings rather than the standard twelve-foot openings and drilling equipment for removal of pillars in excess of 40 feet in height. EXPLORATION Doe Run continues to explore actively within the Viburnum Trend and historically has replaced a significant portion of annual production with new reserves. A development project is on-going in the northern section of the Viburnum-28 mining area with a view to opening additional ore reserves. In addition, limited surface exploration drilling is being conducted in this area. Doe Run is engaged in limited surface diamond drilling beyond the extreme north and south ends of the Viburnum-29 mining area. At Viburnum-35, development activity is focused on developing the eastern blanket ore body access, and in the northern section of the mining area, following the main mineralization trend. Doe Run has initiated a 4,500-foot drift from the northern end of the Brushy Creek mining area to the southern extremity of the Buick mining area. Surface exploration drilling continues in areas south of the present Brushy Creek mining area. Exploration is being actively pursued south of the Fletcher mining area, where mineralization is present but not yet delineated sufficiently to constitute ore reserves. Doe Run also holds exploration tracts outside the Viburnum Trend, which are being actively explored. In fiscal 1997, Doe Run spent $6.2 million on exploration activities, including $2.6 million outside the Viburnum Trend. 75 FACILITIES The following table sets forth the location of and certain other information about Doe Run's facilities:

- ------------------------ (a) FPI is currently relocating its remaining lead oxide manufacturing operations from the Seattle facility to Vancouver, Washington. Upon completion of the relocation, the Seattle facility will be closed. (b) This facility is leased. Doe Run operates three mills and maintains one on stand-by status. The Viburnum mill is located on the eastern edge of Viburnum, Missouri, and has the largest capacity of any mill in the area with its 12,000 ton per day concentrator. Ores from Viburnum-28, Viburnum-29 and Viburnum-35 are processed at the Viburnum mill. The Buick mill is located at the site of the Buick production shaft, and its concentrator has a capacity of 7,200 tons per day. Ores from Buick and Brushy Creek are processed at the Buick mill. The Fletcher mill is located at the site of the Fletcher production shaft, and its concentrator has a capacity of 5,000 tons per day. The Fletcher mill processes ores from the Fletcher production shaft. The Brushy Creek mill is located at the site of the Brushy Creek production shaft, and its concentrator has a capacity of 5,000 tons per day. This mill presently is on stand-by. At the Viburnum mill and Buick mill, lead concentrates are placed in rail cars for transport to the Herculaneum smelter; however, the Fletcher mill does not have rail access, and accordingly, lead concentrates are first trucked to the Buick mill for transport by rail. Zinc and copper concentrates are shipped from the mills to smelter customers by rail or truck. The Herculaneum primary lead smelter is located approximately 35 miles south of St. Louis on the Mississippi River in Herculaneum, Missouri. The St. Joseph Lead Company, a predecessor of Doe Run, built the first smelting operation on the property in 1892. The last reconstruction of the smelter facility was in the mid-1960's. Doe Run owns the smelter property. The recycling facility, with its secondary smelter, located in Boss, Missouri, was constructed in 1991, on the site of a former primary lead smelter. The recycling facility utilizes some of the existing structures and equipment from the primary lead smelter. The primary smelter was originally owned and operated by the Homestake Joint Venture. This property was also acquired initially by Doe Run's Predecessor. In addition to ongoing capital investments, Doe Run has expended an average of approximately $59.5 million per year on maintenance during fiscal 1995 through 1997. As a result of these expenditures and 76 ongoing efforts, Doe Run believes that it operates and will continue to maintain modern and efficient facilities. ELECTRICAL POWER The electric power source for all the facilities, except Viburnum-35, is Union Electric Company, a public utility headquartered in St. Louis, Missouri. Viburnum-35 obtains its electric power from Black River Co-op. RESERVES As of March 31, 1998, Doe Run's Viburnum Trend ore reserves consisted of approximately 8.9 million proven tons and 55.2 million probable tons, containing approximately 3.5 million tons of recoverable lead or approximately fourteen years of production at current mining rates. The term "proven reserves" means ore reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of detailed sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well-established. The term "probable reserves" means ore reserves for which quantity and grade and/or quality are computed from information similar to that used for proven reserves, but the sites for inspection, sampling and measurement are farther apart or otherwise less adequately spaced. The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation. The following table sets forth the mineral inventory and mineable reserves as of March 31, 1998 for Doe Run's Viburnum Trend ore body, which have been audited by Pincock, Allen & Holt, Lakewood, Colorado, an international mineral industry consulting firm. The term "mineral inventory" applies to the mineral zone that has been defined by extensive sampling to define grade and tonnage and can be classified as to various confidence categories, but excludes consideration of recoverability or how the mineralization will be extracted. The term "mineable reserves" refers to the portion of the mineralization that has been defined as extractable for mining purposes, including provision for mining dilution and losses that may occur during extraction, as containing ore of sufficient grade, thickness and tonnage to be economically mineable under normal circumstances, provided reserves are sufficient to justify development costs.

RAW MATERIALS Doe Run's operations utilize various raw materials, principally coke, electricity, natural gas, propane and spent batteries. Doe Run believes that it has adequate sources of these raw materials to meet its present production needs. ENVIRONMENTAL MATTERS Doe Run is subject to numerous federal, state and local environmental laws and regulations governing, among other things, air emissions, waste water discharge, solid and hazardous waste treatment, and storage, disposal and remediation of releases of hazardous materials. In common with much of the mining industry, Doe Run's facilities are located on sites that have been used for heavy industrial purposes for decades and may require remediation. Environmental laws and regulations may become more stringent in the future which could increase costs of compliance. Doe Run is a defendant in several lawsuits alleging certain damages from lead emission stemming from the operations at the Herculaneum smelter. The cases brought in the Circuit Court, 23rd Judicial Circuit at Hillsboro, Jefferson County, Missouri are: KARLA RICHARDSON, ET AL. V. THE DOE RUN RESOURCES CORP., ET AL., Case No. 195-5492-CC-J4, filed September 12, 1995; SARA DIXON, ET AL. V. THE DOE RUN RESOURCES CORP., Case No. 195-5112 CC-J1, filed August 25, 1995; RONALD HEATH, ET AL. V. THE DOE RUN RESOURCES CORP. ET AL., Case No. 195-6936-CC-J2, filed November 20, 1995; and ANDREA MASSA, ET AL. V. THE DOE RUN RESOURCES, ET AL., Case No. 195-7290-CC-J3, filed December 8, 1995. Two of these cases are class action lawsuits. In one case, the plaintiffs seek to have certified two separate classes. The first class would consist of property owners in a certain section of Herculaneum, alleging that property values have been 78 damaged due to the operations of the smelter. The second class alleged is children who lived in Herculaneum during a period of time when they were six months to six years old, and the remedy sought is medical monitoring for the class. The second class action similarly is seeking certification of a class of property owners allegedly damaged by operations from the smelter, but the potential size of the class is every home in Herculaneum, Missouri. The other two cases are personal injury actions by fourteen individuals who allege damages from the effects of lead poisoning due to operations at the smelter. Punitive damages also are being sought in each case. Doe Run is vigorously defending all of these claims. Preliminary investigation and research by Doe Run indicates property values in Herculaneum are consistent with those of surrounding communities and have not been affected by the smelter. Finally, based on rules for class certification, Doe Run believes class certification is not appropriate. However, because the cases are in the early stages of discovery, Doe Run is unable at this time to state with certainty the expected outcome of and the final costs of any of these cases. Therefore, there can be no assurance that these cases would not have a material adverse effect on the results of operations, financial condition and liquidity of Doe Run. Primary smelter slag produced by and stored at the Herculaneum smelter is currently exempt from hazardous waste regulation under the Resource Conservation and Recovery Act of 1976, as amended ("RCRA"). However, the EPA recently published a proposed rule which, if adopted, would require this slag to be managed as a hazardous waste. Certain other waste materials, including baghouse dust, generated at the smelter and now recycled in the smelter may also become regulated as hazardous wastes. At this time, Doe Run cannot predict the final outcome of the EPA's proposed rule. However, if the slag or other wastes at the smelter are regulated as hazardous waste, Doe Run may be required to take corrective action under RCRA at the smelter, as well as to adopt stricter management practices for these wastes, which could have a material adverse effect on the results of operations, financial condition and liquidity of Doe Run. Disposal of the slag at the plant site as a hazardous waste could result in potential capital and operating costs of approximately $1.0 million per year. The area surrounding the Herculaneum smelter currently is out of compliance with the ambient air quality standard for lead promulgated under the federal Clean Air Act. Doe Run is working with regulators to develop a new three-year compliance plan to begin after fiscal 1998 to implement identified control measures. Under the Clean Air Act, there are no penalties for failure to meet the ambient air quality standard. Nevertheless, penalties could be imposed should Doe Run fail to meet the terms of the new three-year compliance plan. Doe Run expects to make capital expenditures for additional control measures totaling approximately $2.8 million for fiscal 1998 while the plan is developed and anticipates a minimum total amount of $3.0 million for the three-year plan. Doe Run has received notice that it is a potentially responsible party ("PRP") subject to liability under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended ("CERCLA"), at the following sites: four sites in St. Francois County, Missouri, including the Big River Mine Tailings site, the Bonne Terre site, the Federal site and the National site; the Oronogo-Durenweg site in Jasper County, Missouri; the Cherokee County site in Cherokee County, Kansas; the Tar Creek site in Ottawa County, Oklahoma; the Block "P" site in Cascade County, Montana; and the Missouri Electric Works site in Cape Girardeau, Missouri. There are four additional sites in St. Francois County for which the EPA has indicated it will issue notice. These sites involve historical operations of predecessors of Doe Run. CERCLA provides for strict and, in certain circumstances, joint and several liability for response costs and natural resource damages. Doe Run has a reserve as of October 31, 1997 of $17.8 million for these sites, including the four additional sites in St. Francois County, which Doe Run believes is adequate based on its investigations to date. However, depending upon the types of remediation required and certain other factors, costs at these sites, individually or collectively, could have a material adverse effect on the results of operations, financial condition and liquidity of Doe Run. 79 Doe Run signed a voluntary Administrative Order of Consent ("AOC") in 1994 with the EPA to remediate the Big River Mine Tailings Site. In February 1997, Doe Run signed an AOC to perform an Engineering Evaluation/Cost Analysis on the Bonne Terre Site. In addition to remediating the mine waste areas at these sites, Doe Run has signed an AOC with the EPA to conduct a Remedial Investigation/ Feasibility Study ("RIFS") to assess potential off-site impacts of site operations on and the need for remediation regarding groundwater, residential soils, several creeks and a river. The RIFS is being conducted by a third party and is approximately one-half complete, with completion expected within one year. Doe Run believes the current reserves assigned to these sites are adequate. However, should remediation goals or areas change, requiring substantially increased measures, there can be no assurance that the reserves would be adequate. The Block "P" site in Montana was a polymetallic mine with a waste facility located on U.S. Forest Service land. Studies of the tailings site, mine and potential impacts on surface water have been requested by the State of Montana. Doe Run has been sued for contribution for superfund remediation costs in RSR CORPORATION AND QUEMETCO V. AVANTI, ET AL., filed on October 11, 1995 in the United States District Court for the Southern District of Indiana. The site in question, known as the Avanti Site located in Indianapolis, Indiana, was a secondary smelter formerly owned by a subsidiary of Doe Run which was sold to RSR in 1972. RSR has entered into an AOC with the EPA to remediate the Avanti Site and claims that Doe Run should reimburse a portion of its costs. It is Doe Run's position that RSR assumed the liabilities of Doe Run's former subsidiary and, in any event, Doe Run has no liability for any acts of its former subsidiary. In June 1996, the EPA issued an order under Section 106 of CERCLA to Doe Run requesting it to make a good faith offer of participation to RSR. Although Doe Run believes it has no liability to RSR, and there are other PRPs named by the EPA and by RSR as defendants in the litigation, Doe Run made what it considers to be a good faith participation offer to RSR of $112,500 which was not accepted. The estimated cost of the selected remedy for the site is $7.0 to 10.0 million. Doe Run does not believe that resolution of this matter will have a material adverse effect on the results of operations, financial condition and liquidity of Doe Run. Doe Run's recycling facility is subject to corrective action requirements under RCRA, as a result of a storage permit for certain wastes issued in 1989. This has required and may involve future remediation of solid waste management units at the site. Although it is not possible to predict whether completed actions will be approved or new actions required, Doe Run has reserves as of October 31, 1997 of $1.9 million for future corrective actions and $2.6 million for closure costs for the permitted storage area. Under the Clean Air Act Amendments of 1990, Congress required the EPA to study certain industry sectors to determine Maximum Achievable Control Technology ("MACT") for each sector. A MACT rule has been adopted which could require substantial capital and operating expenses for the recycling facility. Doe Run challenged the rule by filing a petition for review with the United States Court of Appeals, D.C. Circuit, on August 21, 1995. A settlement with the EPA was reached and published in the Federal Register, which diminishes the need for additional compliance costs. The EPA is also reviewing MACT for primary smelters and in April 1998 proposed a rule to regulate air toxics from primary lead smelters. In the event a MACT rule for primary smelters is adopted by the EPA, the rule could increase compliance costs at the Herculaneum smelter by increasing the costs of administrative reporting requirements. The proposed MACT will also impose additional storage costs. Doe Run's operating facilities have waste water discharge permits issued under the federal Clean Water Act, as amended. It is expected that stricter discharge limits than previously in effect will be included in permits now subject to renewal. As a result, there will be additional treatment facilities required with an anticipated total capital expenditure of $4.0 million over the next five years to meet applicable permit requirements. There will be no appreciable increase in operating costs. 80 Doe Run's mining and milling operations include five mine waste disposal facilities that are subject to Missouri mine closure permit requirements. Doe Run has begun certain closure requirements ahead of closure and is also accruing for the cost of ultimate closure at a rate of approximately $.3 million per year and has a reserve as of October 31, 1997 of $4.8 million. Doe Run has a total reserve as of October 31, 1997 of $28.3 million for CERCLA response costs, corrective action and closure costs as discussed above, $17.8 million of which is for CERCLA response costs. Doe Run expended on all environmental matters, which includes amounts capitalized, amounts charged to operating expense and amounts charged to reserves, approximately $17.5 million in fiscal 1997, and estimates such expenditures will be $16.0 million and $14.5 million in fiscal 1998 and 1999, respectively. SAFETY Throughout its operations, Doe Run strongly emphasizes providing employees a safe working environment through extensive training of employees to ensure safe work practices and worker knowledge of proper equipment operation. Doe Run's mining and milling operations are regulated by MSHA and its smelting and fabricating operations by OSHA. Doe Run believes it has achieved safety results that are among the best in its industry classifications. Each year since 1973, one of Doe Run's mining units has been named either the safest or second safest underground metal mine in the United States by MSHA. Doe Run has achieved the top award ten times in the last 22 years. Doe Run's smelting operations have achieved a strong safety record as well, with typical loss rates averaging approximately three to four times better than industry averages in recent years. EMPLOYEES As of December 31, 1997, Doe Run had 345 active salaried employees and 1,015 active hourly employees. As of December 31, 1997, 13 active hourly employees at Seafab were represented by the Sheet Metal Workers' Union, Local No. 66. Management believes that its labor relations are good. BENEFIT PLANS PENSION Doe Run has defined benefit retirement plans for all salaried employees, hourly employees in Viburnum and Boss and hourly employees in Herculaneum. An investment committee establishes a funding policy for each plan and determines the contributions to be made to each plan by Doe Run. An eligible salaried employee who reaches age 65 receives a right to a nonforfeitable normal retirement annuity equal to 1.5% of his final average salary multiplied by the number of years of his service; eligible hourly employees in Southeast Missouri and in Herculaneum receive a nonforfeitable pension equal to a monthly amount of $25 for each year of service. Salaried employees and hourly employees at both sites who work past the age of 70 1/2 will receive an in-service retirement annuity (based on the same formula) and an in-service monthly pension, respectively. The amount payable under each plan is reduced by the value of benefits each employee received or is entitled to receive under another retirement plan of Doe Run, under retirement plans of Doe Run's Predecessor and certain companies acquired by Doe Run's Predecessor or under any other plan to which Doe Run has contributed other than profit sharing or stock bonus plans. 81 SUPPLEMENTAL EMPLOYEE RETIREMENT PLAN Doe Run has a supplemental retirement plan for employees who participate in Doe Run's pension plans but whose benefits are reduced by the Internal Revenue Code (the "Code"). Under this plan, Doe Run pays eligible employees a benefit equal to the difference between the retirement benefit the employee would have received under the pension plan if the Code were disregarded and the retirement benefit the employee actually is entitled to receive under the pension plan. PROFIT SHARING PROGRAM Eligible employees participate in a Profit Sharing Program under which Doe Run pays 15% of pre-tax income, as defined in the Profit Sharing Program, into a profit sharing pool at the conclusion of each fiscal year. If pre-tax income does not exceed $10.0 million, the profit sharing pool will be distributed to eligible employees in the form of a contribution to Doe Run's Savings Resource Plan (the "401(k) Plan"). If pre-tax income exceeds $10.0 million, the first $1.5 million of the pool will be distributed as a contribution to the 401(k) Plan, and the remaining amount will be distributed in two phases to eligible employees in the form of cash payments. The first phase is a partial distribution based on a preliminary pool calculated from Doe Run's unaudited fiscal year-end financial information, and the second phase is a distribution of any remainder based on a final pool calculated from Doe Run's final audited fiscal year-end financial information. Allocation of the cash payments shall be on the basis of each eligible employee's total fiscal year base pay as a percentage of all eligible employees' total fiscal year base pay. Every employee on the payroll of Doe Run is eligible to participate in any cash distribution; however, participation in a distribution to the 401(k) Plan shall be in accordance with the 401(k) Plan. GAINSHARING PLAN Doe Run's employees participate in a gainsharing plan under which Doe Run pays a bonus based on performance in key result areas. On a monthly and yearly basis, Doe Run determines an improvement factor based on performance in areas such as production (volumes, costs and efficiencies), profit margins, safety and environmental, as well as other key operating areas. Each individual participant's profit share is determined by multiplying this factor by a salary component. PENDING LITIGATION Doe Run is involved in various claims and lawsuits incidental to the ordinary course of its business that are not expected to have a material adverse effect on the results of operations and financial condition of Doe Run. For a description of pending litigation related to environmental matters, see "--Environmental Matters." DOE RUN PERU PRODUCTS Doe Run Peru's principal products include refined copper, silver, zinc, lead and gold. In addition, Doe Run Peru produces a variety of by-products, including bismuth, indium, tellurium, antimony, cadmium, 82 selenium, sulfuric acid, zinc-silver concentrate, zinc sulfate, copper sulfate, arsenic trioxide and others. The following table sets forth net sales for each of Doe Run Peru's principal products.

COPPER Doe Run Peru produces refined copper cathodes with a purity level of 99.975%. Copper sales accounted for $148.9 million of Doe Run Peru's net sales for the twelve months ended October 31, 1997. Peru represented the largest market for Doe Run Peru's copper shipments in 1997, which accounted for 30% of total shipments, followed by the United States and Hong Kong which represented 27% and 16% of total shipments, respectively. In 1997, approximately 38% of the copper cathode production was further processed at the adjacent fabricating facility for the production of copper wirebars and wirerods. The largest market for refined copper, accounting for over 50% of western world copper consumption, is wirerod, which is used almost exclusively in the production of insulated wire and cable. Other important markets for refined copper include copper sheet and strip and tube used in the construction and transportation industries. As part of Doe Run Peru's Capital Investment Program, investments are planned through fiscal 1999 which will improve the cathode quality from standard grade to LME Grade A. In addition, such program will increase the capacity of the copper refinery to match copper anode output from the smelter. Doe Run Peru currently produces standard copper. SILVER Refined silver produced by Doe Run Peru is good delivery 99.996% pure as registered by the LBMA and COMEX. Silver sales accounted for $98.0 million of net sales for the twelve months ended October 31, 1997. Doe Run Peru also produces small amounts of sterling silver directed to the domestic jewelry market. The United States, accounting for 38% of total shipments, represented the largest market for Doe Run Peru's silver, followed by Brazil and Great Britain at 23% and 16% of total shipments, respectively. The photographic film industry accounts for one-third of western world silver demand, and jewelry and silverware also account for one-third. Other important uses for silver include electronics and silver-minted coins. With the additional lead production from the operations of Doe Run Peru, Doe Run is the world's largest primary lead producer. Doe Run Peru and Doe Run intend to work together to take advantage of opportunities to optimize lead marketing efforts. ZINC Doe Run Peru produces LME-registered refined zinc with a purity level of 99.996%. Zinc sales accounted for $83.5 million of Doe Run Peru's net sales for the twelve months ended October 31, 1997. During 1997, Peru represented the largest single market for Doe Run Peru's zinc output, accounting for 83 31% of total shipments, as a result of strong local demand from export-oriented industries with applications for steel coatings, specialized alloys and dry battery plates. The United States represented 25% of total shipments that were primarily exported to manufacturers of coatings, paints and protectants, casters of auto parts and toy manufacturers. LEAD Doe Run Peru produces LME-registered 99.997% pure refined lead ingots and blocks. Lead sales accounted for $65.4 million of net sales for the twelve months ended October 31, 1997. Doe Run Peru also provides antimonial lead alloys to meet the specialty demands of certain customers. The three largest markets for Doe Run Peru's lead production in 1997 were Taiwan, accounting for 14% of total shipments, followed by Brazil and Korea which each represented 10% of total shipments. The largest market for refined lead remains lead-acid batteries used in automobiles, forklifts, golf carts, marine applications and stationary applications for backup power sources. Other markets for refined lead include lead compounds used in the manufacture of computer and television screens and rolled and extruded lead products for radiation shielding and roofing materials. GOLD BULLION Doe Run Peru produces 99.8% pure gold bullion bars exported primarily to Europe and the United States. Gold bullion sales accounted for $14.6 million of net sales for the twelve months ended October 31, 1997. During 1997, the United States represented 44% of total shipments, followed by Germany and Peru, accounting for 40% and 16% of total shipments, respectively. BY-PRODUCTS Principal by-products produced by Doe Run Peru include bismuth, indium, tellurium, antimony and cadmium. Sales of these by-products totaled $21.5 million for the twelve months ended October 31, 1997. Bismuth, the largest by-product revenue generator, is exported primarily to Europe. Bismuth has a wide variety of uses including pharmaceutical compounds, chemicals, low melting alloys and pigments. Pharmaceutical uses include the treatment of stomach ulcers and over-the-counter products. Indium is consumed primarily in the flat-panel display industry, as well as in aerospace products, architectural glass, solar energy and lighting applications. Indium is a difficult metal to extract because of its considerable chemical affinity to other elements. Japan is estimated to account for more than 50% of the world indium market for use in the thin-film industry. Tellurium is used to improve the machining quality of copper and stainless steel products and to color glass and ceramics. Other industrial uses include thermoelectric devices, rubber compounds and blasting caps. Antimony is used with lead in alloys for battery production in flame retardants, fabrics, plastics and ammunition. Cadmium is used primarily for battery production, as well as in pigments, coating and plating of iron, plastic and synthetic products and alloys. MARKETING AND SALES Doe Run Peru's marketing and sales strategy is to maximize the net realized selling prices for all its products. In addition, Doe Run Peru is shifting the focus of its marketing efforts to end users of its products from international trading companies. In furtherance of this strategy, Doe Run Peru plans to provide customers flexible quantities and deliveries, additional metal alloy choices and technical assistance. Doe Run Peru generally exports metal on a delivered basis with freight charges included. In many of the foreign markets, sales agents are utilized to ensure smooth delivery and to help further develop the local market. Doe Run Peru's location in the central Andes of Peru and its proximity to the Callao port 84 position it favorably for shipment to major world markets and to the emerging Latin American market. Metal sales within Peru are sold both on a delivered and "free on board" basis from facilities in Callao. Doe Run Peru plans to market additional metal into the Latin American market in order to take advantage of lower freight costs and strong metal premiums. Doe Run currently is actively involved in several industry associations promoting and developing lead consumption. Through Doe Run Peru, Doe Run plans to gain membership and or to continue membership in other metal industry associations. CAPITAL INVESTMENT PROGRAM Doe Run Peru will undertake over a ten-year period the Capital Investment Program of approximately $300.0 million to enhance various elements of Doe Run Peru's operations. The objective of the Capital Investment Program is to increase net sales and EBITDA by improving product quality, increasing production capacity and reducing unit costs. In addition, through the environmental expenditures described below, Doe Run Peru will endeavor to achieve compliance with environmental regulations in Peru. See "--Environmental Matters." Management believes that cash flow from operations in addition to availability under the New Doe Run Peru Revolving Credit Facility will be sufficient to fund the Capital Investment Program. See "Management's Discussion and Analysis of Financial Condition and Results of Operations." The following summarizes the Capital Investment Program including expenditures planned for each metal circuit. COPPER CIRCUIT Doe Run Peru has identified the copper circuit as the most important of the strategic initiatives to improve its operations, requiring total expenditures, including sustaining capital requirements, of approximately $60.0 million through fiscal 2007. Current projects are designed to increase capacity and reduce energy costs through oxygen injection into the furnaces. These projects will be supplemented in the near term with investments to replace production of copper blister with higher quality fire-refined copper anodes prior to the electrolytic refining process. With the introduction of anode casting, Doe Run Peru anticipates that the refined copper produced will meet the LME-registered quality standards (commonly known as Grade A) as opposed to the standard grade presently produced. As of March 31, 1998, the price for Grade A copper was $.79 per pound, with the price for standard grade copper at a discount to the Grade A price. Doe Run Peru also believes that, as a result of these projects, refined copper production capacity will increase from approximately 73,000 tons to 88,000 tons per year by the year 2000, thereby more closely matching refinery capacity with smelter output. The production of Grade A copper will allow Doe Run Peru to sell to a wider range of customers. Moreover, since the prices realized for Grade A copper are greater than those realized for standard grade copper, Doe Run Peru will be able to realize greater net sales. LEAD CIRCUIT Utilizing Doe Run's extensive experience in lead operations, Doe Run Peru has identified several opportunities to introduce Doe Run operating procedures to increase production capacity and reduce costs. Specific projects include improving oxygen availability to the sinter plant and blast furnaces, enlarging one blast furnace and refurbishing the refinery cell blocks. The combination of these capital projects are expected to increase lead production capacity from approximately 110,000 tons to 127,000 tons per year by the year 2000. Doe Run Peru anticipates that the cost of the lead circuit improvements, including sustaining capital requirements, will be approximately $20.0 million through fiscal 2007. 85 ZINC CIRCUIT Doe Run Peru anticipates investing approximately $18.0 million, including sustaining capital requirements, in the zinc circuit through fiscal 2007, primarily to improve metallurgical recoveries and to retrofit an existing sulfuric acid plant. The installation of an additional purification stage prior to electrowinning will improve the removal of copper, cadmium, cobalt and other impurities, thereby increasing overall zinc recoveries, allowing greater feed flexibility and reducing concentrate purchases and unit operating costs. Presently, Doe Run Peru's zinc production capacity is approximately 77,000 tons which will remain relatively stable in the forseeable future. ENVIRONMENTAL IMPROVEMENTS As part of the Acquisition, Doe Run Peru entered certain agreements with the MEM. Under these agreements, Doe Run Peru is required to make the Investment Commitment that includes expenditures to comply with environmental regulations in Peru, including those governing the treatment, handling and disposal of solid wastes, liquid effluent discharges and gaseous emissions. Principal projects related to environmental matters include building sulfuric acid plants for the metal circuits, new converter and roaster technology for the copper circuit, replacement of the roaster equipment for the zinc circuit, water and sewage treatment facilities, and slag and slimes handling equipment and disposal facilities. Doe Run Peru estimates that expenditures related to environmental matters will be approximately $195.0 million through fiscal 2007. See "--Environmental Matters." OTHER Doe Run Peru will invest approximately $7.0 million over the ten-year period for various other projects, including phone and computer system upgrades, expenditures related to employee health and safety, and other miscellaneous capital expenditures. CUSTOMERS Doe Run Peru had approximately 421 customers in 1997, of which the five largest accounted for approximately 28% of its net sales. Doe Run Peru's customers include a wide variety of industrial and international trading companies with the two largest, Engelhard Corporation and Tecnofil S.A., accounting for approximately 9.8% and 5.1%, respectively, of Doe Run Peru's 1997 net sales. Approximately 78% of total shipments and approximately 79% of net sales were exported outside of Peru, with Latin American countries representing the largest destination in 1997 with approximately 47% of net sales, followed by North America, Asia and Europe with 26%, 18% and 9% of net sales, respectively. Approximately 80% in 1997 of Doe Run Peru's metal sales were pursuant to contractual agreements, typically one year or less. Such contracts generally set forth minimum volumes and pricing mechanisms. COMPETITION Doe Run Peru is among the largest metal processing companies in the world with the unique combination of base metal smelters, refineries and by-product circuits capable of processing complex concentrates into base and precious metals and various by-products to international quality standards. Only three other facilities in the western world, Union Miniere S.A.'s facility in Hoboken, Belgium, Boliden Limited's facility in Ronnskar, Sweden and The Goldfield Corporation's facility in Tsumeb, Namibia, have the capability to treat lead and copper concentrates containing high antimony, arsenic, bismuth and precious metal values in addition to a variety of residues. Unlike Doe Run Peru, none of the facilities listed above have a dedicated zinc production circuit. Given Doe Run Peru's access to complex concentrates in Peru and neighboring Latin American countries, Doe Run Peru believes it operates at a geographic competitive advantage to comparable facilities located farther from their sources of complex concentrates. 86 Although there are other facilities throughout the world that process complex concentrates, those operations do not have Doe Run Peru's capability to process complex concentrates which contain high levels of impurities, such as bismuth, arsenic and cadmium. Such facilities include Industrias Penoles S.A.'s facility in Torreon, Mexico and Dowa Mining Co. Ltd.'s facility in Kosaka, Japan. RAW MATERIALS Doe Run Peru's primary raw material is concentrate feedstock. In addition to concentrate feedstock, Doe Run Peru utilizes various raw materials, principally water, electricity, oxygen, coal and fluxes. CONCENTRATE FEEDSTOCK Doe Run Peru is located in the central Andes of Peru, which is among the most productive mining regions in the world. Peruvian concentrates typically contain high levels of precious metals in addition to impurities such as arsenic, antimony, bismuth and others, that increase the complexity of the metallurgical processes required to separate impurities from base and precious metals. Doe Run Peru's operations were designed and customized since its construction in 1922 to handle the characteristics of raw materials available in the region. COPPER. During 1997, approximately 84% of the copper concentrates processed at Doe Run Peru were supplied from the Peruvian domestic market, with Centromin's mines accounting for a substantial portion of the total feedstock. Contained copper production by Peruvian mines totaled approximately 529,000 tons in 1996 and increased to approximately 579,000 tons in 1997. The complexity of some concentrates from the domestic market result in favorable concentrate pricing terms for Doe Run Peru and increased revenues from the recovery and commercialization of by-products. In addition, due to its location close to the mines of Peru, the smelter is able to save substantially on concentrate freight charges. These savings typically are shared between Doe Run Peru and the concentrate suppliers. Doe Run Peru obtains the balance of its copper concentrate requirements from neighboring Latin American countries. Such concentrates share similar metallurgical characteristics as Peruvian concentrates. Imported concentrates reflect international market terms and are purchased to produce the appropriate concentrate blend for the smelter. ZINC. During 1997, all of the zinc concentrates processed at Doe Run Peru were supplied from the Peruvian domestic market, with Centromin's mines accounting for approximately 94% of the total feedstock. The disadvantage of consuming concentrates from certain of the Centromin mines is the high level of contained iron. Zinc ferrites form in the leaching phase in an amount proportional to the iron content in the feedstock. These ferrites capture approximately 10% to 13% of the zinc contained in the concentrate feedstock and effectively reduce the metallurgical recovery of the circuit. As a private enterprise, Doe Run Peru will not face any limitations with respect to sources of concentrate and, thus, will have an opportunity to obtain concentrates with reduced iron content. Zinc metal contained in concentrates produced by Peruvian mines was approximately 804,000 tons in 1996 and increased substantially to approximately 961,000 tons in 1997. Doe Run Peru requires approximately 70,000 tons of zinc metal contained in concentrates per year. With present mine production, Doe Run Peru believes that sufficient concentrates will be available to meet its requirements for the foreseeable future. LEAD. During 1997, approximately 99% of the lead concentrates processed at Doe Run Peru were supplied from the Peruvian domestic market, with Centromin's mines accounting for approximately half of the total feedstock. Contained lead metal production by Peruvian mines totaled approximately 273,000 tons in 1996 and increased to approximately 287,000 tons in 1997. Since Doe Run Peru has no local Peruvian competitor in lead smelting, all of the concentrates, the total of which far exceeds Doe Run Peru's requirements, are available to Doe Run Peru. 87 A majority of the lead concentrates purchased by Doe Run Peru contain certain impurity levels that result in lower concentrate prices due to penalties imposed on such concentrates. In addition, such concentrates increase revenues for Doe Run Peru due to the recovery and marketing of silver and by-products. WATER Water is utilized throughout Doe Run Peru's operations, particularly for: (i) slag granulation in copper and lead processes; (ii) cooling systems of the sulfuric acid plant, lead blast furnaces, compressors and rectifiers; (iii) steam generation; and (iv) hydrometallurgical and electrometallurgical processes. Water for the Doe Run Peru facility is obtained from three main sources: the Mantaro River; the Tishgo River; and the Cuchimachay Spring. Doe Run Peru believes these three sources, in addition to numerous adjacent springs and wells, provide adequate water supply for the facility. ELECTRICITY The Doe Run Peru facility receives electric power from Centromin's Electroandes hydroelectric division and consumes approximately 63 megawatts ongoing load, which represents approximately one-third of the division's capacity. Doe Run Peru recently signed a ten-year power supply contract with Centromin and Electroandes. Doe Run Peru believes that the contract provides sufficient power to Doe Run Peru over the life of the contract at satisfactory long-term rates. Such rates, however, are above what Doe Run Peru's Predecessor historically paid. OTHER Doe Run Peru installed an oxygen plant in 1994 that, with a capacity of 353 tons per day. The oxygen plant supplies oxygen for the oxy-fuel burners of the reverberatory furnace of the copper smelter and for the blast furnaces of the lead smelter. Coal is imported from Colombia to produce metallurgic coke for the lead circuit blast furnaces. Fluxes consumed in the smelting process are supplied from Doe Run Peru's limestone and silica deposits adjacent to the facility. Both coal and fluxes are transported to the smelter by rail. PRODUCTION PROCESS Doe Run Peru utilizes conventional pyrometallurgical processes for smelting or roasting concentrates followed by hydrometallurgical refining processes. Summarized below is a description of the production process for copper, silver and gold, zinc and lead. COPPER CIRCUIT The copper circuit consists of the smelter, responsible for processing copper concentrates into a 98.6% pure copper blister, and the refinery, responsible for upgrading copper blister into 99.975% pure refined copper metal. Current estimated annual capacity at the refinery is 73,000 tons. Production of refined copper reached approximately 71,000 tons for 1997. Doe Run Peru's overall metallurgical recovery of copper is approximately 96.5%. Copper concentrates are mixed with fluxes and inter-plant transfers in the preparation plant prior to entering the roasting section. The roasters produce a calcine from the copper concentrates that is transported to the oxygen-fuel reverberatory furnace. The reverberatory furnace produces two products: a heavy matte containing the recoverable metals and a slag waste-product that is granulated in water and transported to a slag disposal area. The hot matte is then ladled to the converter section where a two step process converts the matte into 98.6% copper blister that is directly cast into 584 pound blister anodes. 88 The copper refinery is located three kilometers west of the smelter where blister anodes are received from the smelter by rail. The refinery utilizes an electrolytic process whereby the copper in the blister anode is transferred to a cathode starting sheet. As the copper anode dissolves, gold, silver, and other impurities are deposited at the bottom of the cells as an insoluble slime that is collected at the end of the anode cycle. Copper cathodes, which are 99.975% refined copper metal, are collected from the tankhouse every seven days. ZINC CIRCUIT The zinc circuit employs conventional roasting, leaching and electrowinning technologies. During 1997, the circuit produced approximately 75,000 tons of refined zinc. Current estimated capacity of the zinc refinery is approximately 77,200 tons of refined zinc with an overall metallurgical recovery of 88%. The roasting plant produces a calcine that is processed continuously in a hydrometallurgical leaching and purification section that dissolves the zinc oxides and sulfates contained in the calcine. The zinc sulfate solution is separated from solid residues by thickening and filtering processes. After purification, the solution is pumped to the electrowinning section. The zinc refinery is adjacent to the roaster and utilizes an electrolytic process whereby zinc from the sulfate solution is transferred to a cathode starting sheet. Solid residues from the leaching process are processed in a flotation plant to produce a zinc-silver concentrate sold to international markets. Certain remaining unprocessed zinc ferrites are sent to a disposal pond. Zinc cathodes, which are 99.996% refined zinc metal, are collected from the tankhouse every sixteen hours. LEAD CIRCUIT The lead circuit consists of the smelter, responsible for processing lead concentrates into 96% pure lead bullion, and the refinery, responsible for upgrading lead bullion into 99.997% pure refined lead metal. Current estimated annual capacity of the lead refinery is approximately 110,000 tons of lead metal. Production of refined lead metal reached approximately 108,000 tons for 1997. Doe Run Peru's overall metallurgical recovery of lead is approximately 95%. Lead concentrates are mixed with inter-plant transfers and other lead bearing materials in the preparation plant prior to entering the sinter plant. The sinter plant utilizes an up-draft sinter machine that removes a majority of the sulfur from the feedstock. Following sintering, the processed material is blended with coke and fed to the blast furnace to produce two products: a heavy bullion containing the recoverable metals and a slag waste-product that is granulated in water and transported to a slag disposal area. The hot bullion is then transferred to the dross plant for further processing prior to casting into lead bullion anodes. The lead refinery is located three kilometers west of the smelter where bullion anodes are received from the smelter by rail. The refinery utilizes an electrolytic process whereby the lead in the blister anode is transferred to a cathode starting sheet. As the lead anode dissolves, gold, silver, and other impurities are deposited at the bottom of the cells as an insoluble slime that is collected at the end of the anode cycle. Lead cathodes, which are 99.995% refined lead metal, are collected from the tankhouse every four days. 89 ANODE BY-PRODUCTS CIRCUIT AND SILVER REFINING The anode residue plant treats insoluble slimes remaining from the copper and lead refining processes. The plant processes these slimes to recover bismuth, selenium, tellurium and a metal ore that is further upgraded in the silver refinery. The estimated capacity of the silver refinery is approximately 26.2 million ounces per year of refined silver and approximately 76,000 ounces of gold bullion. During 1997, the silver refinery produced approximately 22.4 million ounces of silver and approximately 44,000 ounces of gold bullion. Presently, the capacity of the silver refinery is being increased to 32.2 million ounces per year. FACILITIES Doe Run Peru's operations are located in the town of La Oroya, located approximately 110 miles from the Peruvian capital of Lima, approximately 75 miles from the Cerro de Pasco mine and approximately 78 miles from the city of Huancayo, at an altitude of approximately 2.3 miles above sea level. The complex is linked to these locations by highway and railroad service. The principal operations reside in two areas within La Oroya. The copper smelter, lead smelter and zinc refinery, in addition to the antimony plant, arsenic plant, coke plant, cadmium plant and maintenance shops are located on the southern bank of the Mantaro River directly behind the central offices (the "Smelter Location"). The copper refinery, lead refinery, copper fabricating plant and several storage yards are located three kilometers west of the smelter facilities at Huaymanta (the "Refinery Location"). The following table sets forth the total land area and facility size of Doe Run Peru's facilities:
SIZE ------------------------- FACILITY LAND FACILITY - ---------------------------------------------------------------------- ----------- ------------ (SQUARE (ACRES) FEET) Copper Smelter........................................................ 3.5 302,000 Lead Smelter.......................................................... 3.1 262,000 Copper and Lead Refinery.............................................. 6.9 311,000 Zinc Refinery......................................................... 4.3 258,000 Solid Disposal Area................................................... 110.3 -- Other Areas........................................................... 11.4 554,000
Operations at the Smelter Location began in 1922 under the Cerro de Pasco Copper Corporation, and the Smelter Location continues to utilize many of the original structures. Additions to the Smelter Location include a new lead sinter plant installed in 1983 and the oxygen plant completed in 1994. Operations at the Refinery Location also began in 1922, and many of the existing structures remain in use. Other major additions to the Refinery Area include the wirerod plant constructed in 1966 and additional refinery cell blocks added in the mid-1970s. SAFETY Doe Run Peru's safety performance has improved significantly since 1990, and with further assistance and direction provided by Doe Run, Doe Run Peru will continue to maintain a high regard for safety and hygiene. Recently, Peru's Ministerio de Trabajo y Promocion Social (the Industrial Safety Department) has been enforcing measures to minimize any work-related illnesses or accidents through continuous inspections to ensure compliance with numerous safety standards. EMPLOYEES As of December 31, 1997, Doe Run Peru employed 846 active salaried employees and 2,060 active hourly employees. In addition, Doe Run Peru employed 895 people on a contract basis for production work-orders, maintenance and other tasks. 90 There are two unions for hourly employees and two unions for salaried employees. The principal union representing 90.4% of the hourly employees is the Sindicato de Trabajadores Metalurgicos La Oroya (La Oroya Metallurgic Workers Union). The Sindicato de Trabajadores Ferroviarios La Oroya (La Oroya Railway Workers Union) represents 3.8% of the hourly workers, and the remainder of the hourly workers (5.8%) are not affiliated with either union. Historically, as a government-owned enterprise, Doe Run Peru entered into twelve-month labor agreements, which end on July 25 of each year. Upon the expiration of the previous contract on July 25, 1997, there was no interruption of work, and Doe Run Peru's Predecessor successfully concluded negotiations and reached an agreement on September 21, 1997 that will expire on July 25, 1998. The salaried employees are represented by the Sindicato de Empleados Yauli-La Oroya (Yauli-La Oroya Employees Union), representing 64.9% of the salaried employees and by the Sindicato de Empleados Ferroviarios La Oroya (La Oroya Railway Employees Union), representing 9.0% of salaried employees. The remainder of salaried employees, 26.1%, are not affiliated with either union. The salaried employees' labor agreement expired on December 31, 1997, and negotiations are in progress for a new agreement for 1998. Management believes that Doe Run Peru's labor relations have been good as evidenced by three consecutive years of labor harmony without strikes and likewise three consecutive years of solution without conflict of the labor agreements with workers and employees. As a private enterprise, management contemplates negotiating longer-term labor agreements in 1998 satisfactory to both management and labor. BENEFIT PLANS The benefit plan for Doe Run Peru is centered around a severance payment, a social benefit directed by the Compensacion por Tiempo de Servicios, a Peruvian labor legislative decree. This benefit includes a money reserve established by the employer and deposited in a banking entity for the benefit of the worker when the employment relationship ends. Deposits are made twice a year and equal one month's salary. Other benefits include a social security system operated by the Peruvian government which provides benefits for both health and pensions. In addition to social security, Doe Run Peru maintains a private system of private pension, the cost of which is paid by the employee through paycheck deductions. ENVIRONMENTAL MATTERS LEGAL FRAMEWORK Modern environmental legislation has been introduced only in the last decade in Peru. For mining and metallurgical activities, the MEM is the principal regulatory authority. The MEM has issued "maximum permissible limits" for liquid effluent, air emissions and ambient air quality. In addition, the Consejo Nacional del Ambiente (National Environmental Council) coordinates government regulations and policies. The Direccion General de Salud Ambiental (Directorate General of Environmental Health) (the "DIGESA"), a division of the Ministerio de Salud (Ministry of Health), issues waste water discharge permits based on standards governing receiving water quality. Peruvian law requires all new mining or metallurgical operations, and existing operations that are undergoing an expansion of over 50% of installed capacity, to submit to the MEM an Estudio de Impacto Ambiental (Environmental Impact Study). As to mining and metallurgical operations in existence prior to 1994, concession holders (i.e. owner/ operators) were required to submit to the MEM an Evaluacion Ambiental Preliminar (Preliminary Environmental Assessment) (the "EVAP") that identified environmental impacts and twelve months of baseline monitoring. Based on the results of the EVAP, the operator was to submit to the MEM a PAMA that consisted of an environmental impact analysis, monitoring plan, and data, mitigation measures and closure plan. The PAMA also sets forth the actions and corresponding annual investments the concession holder agrees to undertake in order to achieve compliance with the maximum applicable limits prior to 91 expiration of the PAMA (ten years for smelters, such as Doe Run Peru's operations, and five years for any other type of mining or metallurgical operation). The required amount of annual investment must not be less than one percent of annual sales. Once approved, the PAMA functions as the equivalent of an operating permit with which the operator must comply. After expiration of the PAMA, the operator must comply with all applicable standards and requirements. Mining, metallurgical and processing operators must present annual sworn statements to the MEM that describe their operations and resultant emissions. In addition, Peruvian environmental law allows operators to enter into a Contrato de Estabilidad Administrativa Ambiental (Contract for Administrative Environmental Stabilization) ("Environmental Stabilization Agreement") in order to provide some potential limit to the applicability of new laws during the life of the PAMA. PAMA AND ENVIRONMENTAL STABILIZATION AGREEMENT The initial PAMA for Doe Run Peru's Predecessor was submitted by Centromin and approved by the MEM on January 13, 1996. The PAMA was modified in connection with the Acquisition to reflect a reallocation of environmental responsibilities between Centromin and Doe Run Peru, and corresponding revisions were made to the investment schedule. The MEM approved separate PAMAs for Centromin and Doe Run Peru and an Environmental Stabilization Agreement for Doe Run Peru. Centromin has committed under its PAMA to implement the following projects over the next nine years, estimated to cost approximately $24 million: (i) remediation of areas impacted by emissions during its period of operations; (ii) closure of the lead and copper slag deposits (at Huanchan); (iii) improved management of the Huanchan deposit (E.G. storm water diversion and slope stability); and (iv) closure of the arsenic trioxide deposits (at Malpaso and Vado). Doe Run Peru has committed under its PAMA to implement the following projects over the next nine years, estimated in the PAMA to cost approximately $107.5 million: (i) new sulfuric acid plants; (ii) elimination of fugitive gases from the coke plant; (iii) use of oxygenated gases in the anodic residue plant; (iv) water treatment plant for the copper refinery; (v) a recirculation system for cooling waters at the smelter; (vi) management and disposal of acidic solutions at the silver refinery; (vii) industrial waste water treatment plant for the smelter and refinery; (viii) containment dam for the lead muds near the zileret plant; (ix) granulation process water at the lead smelter; (x) anode washing system at the zinc refinery; (xi) management and disposal of lead and copper slag wastes; and (xii) domestic waste water treatment and domestic waste disposal. The actual current estimate for the environmental projects and related process changes for Doe Run Peru is $195.0 million. Doe Run Peru's operations historically and currently exceed some of the applicable MEM maximum permissible limits pertaining to air emissions, ambient air quality and waste water effluent quality. The PAMA projects, which are more fully discussed below, have been designed to achieve compliance with such requirements prior to the expiration of the PAMA on January 13, 2007. No assurance can be given that implementation of the PAMA projects is feasible or that their implementation will achieve compliance with the applicable legal requirements by the end of the PAMA period. Doe Run Peru has advised the MEM that it intends to seek changes in certain PAMA projects that it believes will more effectively achieve compliance. However, there can be no assurance that the MEM will approve proposed changes to the PAMA or that implementation of the changes will not increase the cost of compliance. Further, there can be no assurance that the Peruvian government will not in the future require compliance with additional environmental obligations that could adversely affect Doe Run Peru's business, financial condition or results of operations. Under the Subscription Agreement, Centromin agreed to indemnify Metaloroya against environmental liability arising out of its prior operations, and performance of the indemnity has been guaranteed by the Peruvian government through the enactment of the Supreme Decree No. 042-97-PCM. However, there can be no assurance that Centromin will satisfy its environmental obligations and investment requirements, including those in its PAMA, or that the guarantee will be honored. Any 92 failure by Centromin to satisfy its environmental obligations could adversely affect Doe Run Peru's business, financial condition or results of operations. ENVIRONMENTAL CONSIDERATIONS GASEOUS EMISSIONS. Doe Run Peru is required to control gaseous emission to meet ambient air quality standards and the applicable emissions rate by January 2007. In 1997, sulfur dioxide emissions from the smelter complex amounted to approximately 990 tons per day. The MEM has established a maximum sulfur dioxide rate for Doe Run Peru of 17% of incoming sulfur based on current production levels. Dust emissions currently total approximately 9.8 tons per day, consisting of approximately 2.5 tons of lead, 2.0 tons of arsenic, 0.3 tons of zinc and smaller quantities of other metals. Although the main stack is the largest source of gaseous emissions, significant quantities of the same effluents are issued from the numerous smaller stacks, as well as from many non-stack sources. LIQUID EFFLUENTS. Doe Run Peru is required to control liquid effluents to meet the MEM's discharge limits and DIGESA's water quality standards. Forty individual discharge sources were identified by the monitoring program of the EVAP as releases from Doe Run Peru to the Yauli and Mantaro Rivers. Liquid effluents contain metals in solution and solids in suspension. Five liquid effluent discharges account for 90% of the total discharge volume from the smelter and refinery facilities. The highest volumetric discharge of the total includes a combination of effluents from the copper-lead slag granulation process and cooling water from the powerhouse. SOLID RESIDUES. The principal solid residues generated by Doe Run Peru's facility are shown below:
RESIDUE ESTIMATED VOLUME - ---------------------------------------------------------------------------- ----------------- (TONS PER MONTH) Copper Slag................................................................. 22,000 Lead Slag................................................................... 14,000 Zinc Ferrites............................................................... 2,400 Arsenic Trioxide............................................................ 280
Granulated copper and lead slag is transported across the Mantaro River by aerial tram and stockpiled at Huanchan. Zinc leaching residue, consisting mainly of zinc ferrites, is pumped into ponds in the same area. Arsenic trioxide is transported by rail to the Vado site, where it is stored under water spray for dust suppression.
DISTANCE FROM DEPOSIT DOE RUN PERU ESTIMATED SIZE - --------------------------------------------------------------- ----------------- -------------- (MILES) (TONS) Huanchan copper and lead slag.................................. 2.5 11,000,000 Zinc Ferrites.................................................. 1.2 1,400,000 Vado arsenic trioxide slag..................................... 5.6 180,000 Malpaso arsenic trioxide slag (historical)..................... 8.7 Unknown
OVERVIEW OF THE ENVIRONMENTAL PROJECTS In accordance with the PAMA, Doe Run Peru has included in its capital expenditure plans specific capital projects to accomplish the goals of the PAMA. Excluding the process-related projects which assist in meeting the environmental requirements, Doe Run Peru's major environmental projects include slag handling, industrial wastewater treatment, sulfur dioxide capture and recovery as sulfuric acid, and sewage and garbage management. The total costs of these projects and associated process changes and other environmental control projects are expected to approach $195.0 million over the next nine years starting in 1998. 93 SLAG HANDLING AND DISPOSAL. A new mechanical slag handling system will be installed for the 1,100 tons of copper and lead slag per day to either dewater granulated slag and deliver it to the ultimate disposal site or to deliver the hot slag to its ultimate disposal site. The objective of the project is to replace the undersized tramway slag system, which currently loses 30% to 40% of the slag into the Mantaro River, with a system capable of safely delivering all slag to its final disposition site and to minimize any discharge of heavy metals into the river. A number of mechanical systems will be evaluated both for continuing granulation and for delivering the material hot. A Trommel dewatering system was outlined in the PAMA. Installation of the dewatering system, when selected, is expected to occur in fiscal 1999. The capital cost for the project is estimated to be $6.0 million. If a new slag site is developed, approximately $3.0 to $5.0 million is expected to be expended in preparing the site. ZINC FERRITE DISPOSAL Doe Run Peru has the option to continue to use the existing disposal site for three years and then either take ownership of it or develop a new site and pay Centromin $7.2 million for closure costs. It is probable that Doe Run Peru will retain ownership of the disposal site and develop a new disposal site on property currently owned for that purpose. The cost of developing this site is expected to be approximately $3.0 to 5.0 million. INDUSTRIAL WASTEWATER TREATMENT. Recycling projects will be implemented to recirculate and reuse wastewater after cooling or intermediate treatment. The water recycling project for slag handling will reduce the 20,000 gallons per minute rate to approximately 3,000 gallons per minute for discharge. An industrial sewer network will be constructed to drain effluent from approximately 35 outfalls to several pumping stations, which, after solids removal, will be treated and discharged to the river. The purpose of this project is to eliminate the untreated discharge of metal bearing wastes into the Mantaro River. This system is different from and more costly than the project set forth in the PAMA. The system will be designed to meet the MEM's discharge limits and DIGESA's water quality standards. However, there can be no assurance that the MEM will approve this project, or that DIGESA will not require additional actions at increased cost. The recycling and pre-treatment steps are expected to be installed in fiscal 1999. The collection systems and sedimentation tanks are expected to be installed in fiscal 2000, and the first stage treatment plant is expected to be installed in fiscal 2001. If a second stage treatment is required, it will be deferred for three to four years. The estimated cost of the project is $25.0 million which reflects local labor rates and the deferral of the second stage treatment, which may not prove to be necessary. Addition of the second stage could cost approximately $2.0 million. SULFUR DIOXIDE CAPTURE AND LEAD EMISSION REDUCTION. The PAMA provides for process gas from the copper, zinc and lead process circuits to be treated in two sulfuric acids plants for the conversion of sulfur dioxide to sulfur trioxide and the recovery as sulfuric acid, a by-product that Doe Run Peru expects to sell. The objective of this project is to increase the capture of sulfur dioxide from approximately 11% to a minimum of 83%, which is the MEM standard. The second objective is to reduce the sulfur dioxide and metal emissions in the ambient air surrounding the plant to within MEM standards. The acid plants will be installed in fiscal 2005 and 2006. The estimated costs of each of the two plants is approximately $39.0 million. The PAMA also provides for replacement of the existing lead circuit with a new technology to assist in insuring at least 83% capture. However, Doe Run Peru does not believe that this process has been adequately demonstrated and likely will seek a change to the PAMA to avoid this process change. Other options are available if needed to meet the sulfur dioxide emission limit, which are estimated to cost in the range of $50.0 to $80.0 million. 94 Given the complex terrain and valley configuration of the Doe Run Peru facility, there can be no assurance that the measures contemplated in the PAMA will achieve compliance with the ambient air quality standard for sulfur dioxide or for lead, particularly during inversion conditions. Other actions, such as altering the present main stack configuration and increased efforts to reduce fugitive emissions, may be necessary at significant increased costs to achieve compliance commencing during the later years of or after the nine-year PAMA compliance period. SEWAGE/GARBAGE MANAGEMENT. Two conventional sewage treatment systems and collection systems will be installed to service the 3,000 employees of Doe Run Peru living in company housing in La Oroya. A garbage collection system and disposal landfill also will be developed. This project is designed to comply with the PAMA and will improve living conditions in La Oroya. The project is intended to eliminate the discharge of raw sewage and garbage by Doe Run Peru to the Yauli and Mantaro Rivers. Planning and design work will begin in fiscal 1998, and construction will follow in the next two years at an estimated cost of $3.0 million. PENDING LITIGATION All existing litigation of Doe Run Peru at the time of the Acquisition was retained by Centromin. Doe Run Peru is involved in various claims and lawsuits incidental to the ordinary course of its business that are not expected to have a material adverse effect on the business, financial condition and results of operations of Doe Run Peru. 95 MANAGEMENT DIRECTORS AND OFFICERS The following table sets forth certain information regarding the directors and executive officers of the Company:

In addition, each of the above executive officers have agreed to maintain the confidentiality of information obtained during their employment with Doe Run. 99 SECURITY OWNERSHIP The following table sets forth certain information as of the date hereof with respect to beneficial ownership of Doe Run's common stock by each beneficial owner of 5% or more of the common stock, each director and each named executive officer of Doe Run during the last fiscal year, and by all directors and executive officers of Doe Run as a group. Except as otherwise noted, the persons named in the table below have sole voting and investment power with respect to all shares or interests, as applicable, shown as beneficially owned by them.
NUMBER OF NAME SHARES PERCENT - --------------------------------------------------------------------------------------------- ----------- ----------- The Renco Group, Inc.(a)(b).................................................................. 1,000 100.0% DR Acquisition Corp.(a)...................................................................... 1,000 100.0 Ira Leon Rennert(a)(c)....................................................................... 1,000 100.0 Jeffrey L. Zelms............................................................................. -- -- Marvin K. Kaiser............................................................................. -- -- Richard L. Amistadi.......................................................................... -- -- Gary E. Boyer................................................................................ -- -- Kenneth R. Buckley........................................................................... -- -- All directors and executive officers of Doe Run as a group (7 persons)....................... 1,000 100.0
- ------------------------ (a) The address of this beneficial owner is c/o The Renco Group, Inc., 30 Rockefeller Plaza, Suite 4225, New York, New York 10112. (b) Renco is deemed to beneficially own the shares owned by DRA due to Renco's ownership of all of the outstanding capital stock of DRA. (c) Mr. Rennert is deemed to beneficially own the interests and shares owned by Renco due to the ownership by himself and trusts established by him (but of which he is not a trustee) for himself and members of his family of a total of 97.9% of the outstanding common stock of Renco. By virtue of Renco's indirect ownership of 100.0% of the outstanding common stock of Doe Run, and Mr. Rennert's ownership of a majority of the stock of Renco, Mr. Rennert is in position to control actions that require the consent of a majority of the holders of equity interests in Doe Run and its subsidiaries. The 2,500 shares of preferred stock of Doe Run, all of which were held by Renco, were redeemed as part of the Transactions. 100 CERTAIN TRANSACTIONS TRANSACTIONS WITH RENCO AND ITS AFFILIATES Under a management consultant agreement, dated as of April 7, 1994, as amended (the "Management Consultant Agreement"), between Renco and Doe Run, Doe Run pays an annual fee of $2.4 million to Renco. The Management Consultant Agreement provides that Doe Run shall not make any payment thereunder which would violate any of its agreements with respect to any of its outstanding indebtedness. The Management Consultant Agreement extends to October 31, 2000 and thereafter shall continue for additional terms of three years each unless sooner terminated by either party by giving six months prior written notice. In the year ended October 31, 1997, Doe Run paid management fees to Renco in the amount of $1.2 million. The Company believes that the cost of obtaining the type and quality of services rendered by Renco under the Management Consultant Agreement was, and continues to be, no less favorable than that at which the Company could obtain such services from unaffiliated entities. To obtain the advantages of volume, Renco purchases certain insurance coverages for its subsidiaries, including Doe Run and Doe Run Peru, and the cost of such insurance, without markup, is reimbursed by the covered subsidiaries. Currently, the major areas of insurance coverage obtained under the Renco programs for Doe Run are property, business interruption and fidelity and for Doe Run Peru are foreign general liability and fidelity, and the premiums for property, business interruption, fidelity and foreign general liability (as applicable) are allocated by Renco to its covered subsidiaries, substantially as indicated in the underlying policies. Renco also purchases and administers certain insurance policies exclusively for Doe Run, including fiduciary, general and product liability, workers' compensation, political risk, automobile liability, and casualty umbrella, and for Doe Run Peru, including property, business interruption, general and product liability, workers' compensation, automobile liability and casualty umbrella. The cost of such insurance, without markup, is reimbursed by Doe Run and Doe Run Peru (as applicable) as incurred. The total insurance cost under the Renco insurance programs incurred in fiscal 1997 by Doe Run was approximately $2.5 million and by Doe Run Peru was DE MINIMIS. Doe Run and Doe Run Peru believe that their insurance costs were less than they would have incurred if they had obtained their respective insurance directly. Pursuant to a tax sharing agreement between Doe Run and Renco, Doe Run pays to Renco an amount equal to the amount Doe Run would have been required to pay for taxes on a stand-alone basis to the Internal Revenue Service and the applicable state taxing authority, as the case may be, except that Doe Run will not have the benefit of any of its tax loss carryforwards unless such tax losses were a result of timing differences between Doe Run's accounting for tax and financial reporting purposes. This agreement also provides that transactions between Doe Run and Renco and its other subsidiaries are accounted for on a cash basis and not on an accrual basis. Beginning in fiscal 1998, Doe Run sold, and may from time to time in the future sell, zinc and other alloys to WCI Steel, Inc., an indirect subsidiary of Renco. Doe Run believes that such sales were on an arm's length basis at a price no less favorable than that at which Doe Run could have sold to unaffiliated entities. INTERCOMPANY TRANSACTIONS Doe Run Peru will pay a sales agency commission to Doe Run Mining pursuant to a sales agency contract, dated as of March 9, 1998, by and between Doe Run Peru and Doe Run Mining. The initial term will be for a period of two years, automatically renewable for additional one-year terms. Under this agreement, Doe Run Mining acts as the sales agent for Doe Run Peru with respect to all sales of Doe Run Peru's products within Peru and receives a commission of 3% of such sales.

Capitalized terms used herein and not otherwise defined have the meanings ascribed to such terms in the loan and security agreement relating to the New Doe Run Revolving Credit Facility. GENERAL The New Doe Run Revolving Credit Facility is provided pursuant to a Loan and Security Agreement, dated March 12, 1998, by and among Doe Run, FPI and Congress Financial Corporation ("Congress"). As of March 31, 1998, $5.0 million (exclusive of outstanding letters of credit) was outstanding under the New Doe Run Revolving Credit Facility. Under the New Doe Run Revolving Credit Facility, Congress will, in its discretion, lend on a revolving basis to Doe Run and/or FPI up to the sum of (a) 85% of the Net Amount of Eligible Accounts plus (b) 60% of the Value of Eligible Inventory (but not more than a loan value of $50.0 million) and (c) 25% of the Value of Eligible Stores Inventory of Doe Run (but not more than a loan value of $2.5 million). Collections from accounts are applied to reduce the loan balance, which may be reborrowed up to the aforesaid limits. Congress may extend up to $10.0 million of letter of credit accommodations within the limits set forth above. INTEREST Interest on the loan balance is payable monthly at the prime rate plus 0.75% per annum. The interest rate on January 31, 1998 would have been 9.25%. In the event of a default under the New Doe Run Revolving Credit Facility, the interest rate will be 2.75% per annum in excess of such prime rate. SECURITY As security for the indebtedness under the New Doe Run Revolving Credit Facility, Doe Run and FPI have granted to Congress a first security interest in all (a) accounts, (b) certain general intangibles, (c) inventory, (d) all present and future books and records relating to the foregoing and (e) all products and proceeds of the foregoing. TERM The New Doe Run Revolving Credit Facility has a three-year term and beginning on March 2001, can be renewed from year to year thereafter, PROVIDED that the agreement may be terminated by any party as of March 2001 or any subsequent anniversary date on 60 days advance written notice. CERTAIN COVENANTS In addition to customary covenants, the New Doe Run Revolving Credit Facility requires that Doe Run and FPI be subject to certain covenants, including, but not limited to, a restriction on the incurrence of additional indebtedness, a restriction on the creation of additional liens, compliance with certain financial covenants, certain restrictions on dividends, loans and investments, restrictions on mergers and sales of assets and certain restrictions on capital expenditures. 103 EVENTS OF DEFAULT The New Doe Run Revolving Credit Facility contains certain events of default, including, without limitation, the following: (i) the failure of Doe Run or FPI to pay any of its obligations under the New Doe Run Revolving Credit Facility within three days after the due date; (ii) certain defaults by Doe Run or FPI under various other indebtedness, in each case after any applicable grace period; (iii) any default by Doe Run or FPI in the performance or observance of the conditions and covenants of the New Doe Run Revolving Credit Facility or related agreements, beyond any applicable cure period; (iv) any representation or warranty made by Doe Run or FPI to Congress under the New Doe Run Revolving Credit Facility proved to be false in any material respect; (v) certain judgments against Doe Run or FPI; (vi) certain events of bankruptcy or insolvency of Doe Run or FPI; or (vii) the occurrence of any change in the control or ownership of Doe Run. NEW DOE RUN PERU REVOLVING CREDIT FACILITY The following is a general description of the anticipated terms of the $40.0 million New Doe Run Peru Revolving Credit Facility. Doe Run Peru currently is negotiating the New Doe Run Peru Revolving Credit Facility. No assurances can be given that Doe Run Peru will be able to enter into such facility on the terms currently anticipated or at all. It is expected that the New Doe Run Peru Revolving Credit Facility will provide for borrowings of up to $40.0 million, which will be based upon certain advance rates regarding eligible receivables and inventory and will be secured by such receivables and inventory and funds deposited in a cash collection account. The New Doe Run Peru Revolving Credit Facility is expected to have a term of four years, with the option, at the sole discretion of the lenders thereunder, to adjust the interest rate thereunder every twelve months. It is expected that the New Doe Run Peru Revolving Credit Facility will contain representations and warranties, covenants and events of default, in each case customary for transactions of this type. 104 DESCRIPTION OF THE NOTES The Old Notes are and the Exchange Notes will be issued under the Indenture among Doe Run, the Guarantors and State Street Bank and Trust Company, as trustee (the "Trustee"). The following summary of the material provisions of the Indenture does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the Indenture, including the definitions of certain terms contained therein and those terms made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the "TIA"), as in effect on the date of the Indenture. A copy of the Indenture is filed as an exhibit to the Registration Statement. The definitions of certain capitalized terms used in the following summary are set forth below under "--Certain Definitions." GENERAL The Notes are general unsecured obligations of Doe Run limited to $355.0 million in aggregate principal amount, of which $200.0 million are Fixed Rate Notes and $55.0 million are Floating Rate Notes. Additional amounts of Notes in an aggregate principal amount of up to $100.0 million may be issued under the Indenture in one or more series from time to time, subject to the limitations set forth under "--Certain Covenants--Limitation on Indebtedness." The Fixed Rate Notes will mature on March 15, 2005. The Floating Rate Notes will mature on March 15, 2003. Principal of, premium, if any, and interest on the Notes will be payable, and the Notes will be exchangeable and transferable, at the office or agency of Doe Run in New York City maintained for such purposes (which initially is the Trustee or its agent); PROVIDED that payment of interest may be made at the option of Doe Run by check mailed to the registered holders of the Notes ("Holders") at their registered addresses. The Notes will be issued only in fully registered form without coupons, in denominations of $1,000 and any integral multiple thereof. No service charge will be made for any registration of transfer, exchange or redemption of Notes, except in certain circumstances for any tax or other governmental charge that may be imposed in connection therewith. INTEREST Interest on the Notes will be payable semi-annually in cash on each March 15 and September 15 (each an "Interest Payment Date") commencing on September 15, 1998, for the period commencing on and including the immediately preceding Interest Payment Date and ending on and including the day next preceding the Interest Payment Date (an "Interest Period"), with the exception that the first Interest Period shall commence on and include March 12, 1998 and end on and include September 14, 1998. Interest is payable to the persons who are registered Holders at the close of business on the March 1 and September 1 immediately preceding the applicable Interest Payment Date. FIXED RATE NOTES Interest on the Fixed Rate Notes accrues at the rate of 11 1/4% per annum. Interest on the Fixed Rate Notes will be computed on the basis of a 360 day year composed of twelve 30 day months. FLOATING RATE NOTES The Floating Rate Notes accrues interest at a rate per annum, reset semi-annually, equal to LIBOR plus 6.29%, as determined by the calculation agent (the "Calculation Agent"), which is the Trustee. "LIBOR," with respect to an Interest Period, shall be the rate (expressed as a percentage per annum) for deposits in United States dollars for a six-month period beginning on the second London Banking Day (as defined) after the Determination Date (as defined) that appears on Telerate Page 3750 (as defined) as of 11:00 a.m., London time, on the Determination Date. If Telerate Page 3750 does not include such a rate or is unavailable on a Determination Date, LIBOR for the Interest Period shall be the arithmetic mean of 105 the rates (expressed as a percentage per annum) for deposits in a Representative Amount (as defined) in U.S. dollars for a six-month period beginning on the second London Banking Day after the Determination Date that appears on Reuters Screen LIBO Page (as defined) as of 11:00 a.m., London time, on the Determination Date. If Reuters Screen LIBO Page does not include two or more rates or is unavailable on a Determination Date, the Calculation Agent will request the principal London office of each of four major banks in the London interbank market, as selected by the Calculation Agent, to provide such bank's offered quotation (expressed as a percentage per annum), as of approximately 11:00 a.m., London time, on such Determination Date, to prime banks in the London interbank market for deposits in a Representative Amount in U.S dollars for a six-month period beginning on the second London Banking Day after the Determination Date. If at least two such offered quotations are so provided, LIBOR for the Interest Period will be the arithmetic mean of such quotations. If fewer than two such quotations are so provided, the Calculation Agent will request each of three major banks in New York City, as selected by the Calculation Agent, to provide such bank's rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on such Determination Date, for loans in a Representative Amount in U.S. dollars to leading European banks for a six-month period beginning on the second London Banking Day after the Determination Date. If at least two such rates are so provided, LIBOR for the Interest Period will be the arithmetic mean of such rates. If fewer than two such rates are so provided, then LIBOR for the Interest Period will be LIBOR in effect with respect to the immediately preceding Interest Period. "Determination Date," with respect to an Interest Period, will be the second London Banking Day preceding the first day of the Interest Period. "London Banking Day" is any day in which dealings in U.S. dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market. "Representative Amount" means a principal amount of not less than U.S. $1,000,000 for a single transaction in the relevant market at the relevant time. "Telerate Page 3750" means the display designated as "Page 3750" on the Dow Jones Telerate Service (or such other page as may replace Page 3750 on that service). "Reuters Screen LIBO Page" means the display designated as page "LIBO" on The Reuters Monitor Money Rates Service (or such other page as may replace the LIBO page on that service). The amount of interest for each day that the Floating Rate Notes are outstanding (the "Daily Interest Amount") will be calculated by dividing the interest rate (expressed as a percentage per annum) in effect for such day by 360 and multiplying the result by the principal amount of the Floating Rate Notes. The amount of interest to be paid on the Floating Rate Notes for each Interest Period will be calculated by adding the Daily Interest Amounts for each day in the Interest Period. All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (E.G., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards). The interest rate on the Floating Rate Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by U.S. law of general application. Under current New York law, the maximum rate of interest is 25% per annum on a simple interest basis. This limit may not apply to Floating Rate Notes in which $2,500,000 or more has been invested. The Calculation Agent will, upon the request of the Holder of any Floating Rate Note, provide the interest rate then in effect with respect to the Floating Rate Notes. All calculations made by the Calculation Agent in the absence of manifest error shall be conclusive for all purposes and binding on Doe Run and the Holders of the Floating Rate Notes. 106 OPTIONAL REDEMPTION The Fixed Rate Notes will be subject to redemption, in whole or in part, at the option of Doe Run, at any time on or after March 15, 2002, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued interest to the redemption date, if redeemed during the twelve month period beginning on March 15 of the years indicated below:
YEAR PERCENTAGE - ---------------------------------------------------------------------------------- ----------- 2002.............................................................................. 105.625% 2003.............................................................................. 102.813% 2004 and thereafter............................................................... 100.000%
The Floating Rate Notes are subject to redemption, in whole at any time or in part from time to time, at the option of Doe Run, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued interest to the redemption date, if redeemed during the twelve month period beginning on March 15 of the years indicated below:
YEAR PERCENTAGE - ---------------------------------------------------------------------------------- ----------- 1998.............................................................................. 104.000% 1999.............................................................................. 103.000% 2000.............................................................................. 102.000% 2001.............................................................................. 101.000% 2002 and thereafter............................................................... 100.000%
OPTIONAL REDEMPTION OF FIXED RATE NOTES UPON EQUITY OFFERINGS In addition, at any time prior to March 15, 2001, Doe Run may redeem up to 35% of the sum of (x) the aggregate principal amount of the Fixed Rate Notes issued in the Old Notes Offering plus (y) any additional Fixed Rate Notes issued after the Issue Date pursuant to the Indenture, with the proceeds of one or more Equity Offerings at a redemption price (expressed as a percentage of principal amount) of 111.25% plus accrued interest to the redemption date; PROVIDED that at least 65% of the sum of (x) the aggregate principal amount of Fixed Rate Notes issued in the Old Notes Offering plus (y) any additional Fixed Rate Notes issued after the Issue Date pursuant to the Indenture remains outstanding immediately after any such redemption. In order to effect the foregoing redemption with the proceeds of any Equity Offering, Doe Run shall make such redemption not more than 120 days after the consummation of any such Equity Offering. "Equity Offering" means an offering of Qualified Capital Stock of Doe Run (other than to any Subsidiary of Doe Run). SINKING FUND There will be no mandatory sinking fund payments for the Notes. SELECTION AND NOTICE OF REDEMPTION In the event that less than all of the Notes are to be redeemed at any time, selection of such Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange or quotation system, if any, on which such Notes are listed or, if such Notes are not then listed on a national securities exchange or quotation system, on a PRO RATA basis, by lot or by such method as the Trustee shall deem fair and appropriate; PROVIDED, HOWEVER, that (i) no Notes of a principal amount of $1,000 or less shall be redeemed in part and (ii) a redemption of Fixed Rate Notes with the net cash proceeds of an Equity Offering shall be made on a PRO RATA basis unless such method is otherwise prohibited. Notice of redemption shall be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. If any Note 107 is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the redemption date, interest will cease to accrue on Notes or portions thereof called for redemption. GUARANTEES Doe Run's obligations under the Notes are guaranteed in the manner described below by the following Subsidiaries of Doe Run, FPI, Doe Run Cayman, Doe Run Mining and Doe Run Peru, and, in the future, may be guaranteed by certain of Doe Run's Restricted Subsidiaries. See "--Certain Covenants--Future Guarantees." The only existing Subsidiary of Doe Run that is not a Guarantor is DR Exploration. The laws of South Africa, DR Exploration's jurisdiction of organization, may not permit DR Exploration to be a Guarantor. Each Guarantor unconditionally guarantees, on a senior basis (except as described below under "--Ranking" with respect to the Guarantee of Doe Run Peru), jointly and severally, to each Holder and the Trustee, the full and prompt performance of Doe Run's obligations under the Indenture and the Notes, including the payment of principal of and interest on the Notes. The obligations of each Guarantor are limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under the Indenture, will result in the obligations of such Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law, in the case of domestic Guarantors, or any applicable foreign law, in the case of foreign Guarantors. Each Guarantor that makes a payment or distribution under a Guarantee shall be entitled to a contribution from each other Guarantor in an amount PRO RATA, based on the net assets of each Guarantor determined in accordance with GAAP. Each Guarantor may consolidate with or merge into or sell its assets to Doe Run or to another Guarantor that is a Wholly-Owned Restricted Subsidiary without limitation, or with other persons upon the terms and conditions set forth in the Indenture. See "--Certain Covenants--Merger, Consolidation and Sale of Assets." In the event that either all of the Capital Stock of a Guarantor is sold by Doe Run or one of the Restricted Subsidiaries (whether by merger, stock purchase or otherwise) or all or substantially all of the assets of a Guarantor are sold by such Guarantor and such sale complies with the provisions set forth in "--Certain Covenants--Limitation on Sale of Assets" and "--Change of Control" and any other applicable provisions in the Indenture, the Guarantor's Guarantee will be released. RANKING Except as described below with respect to the Guarantee of Doe Run Peru, the indebtedness of Doe Run and the Guarantors evidenced by the Notes and the Guarantees rank senior in right of payment to all future unsecured senior subordinated and subordinated indebtedness of Doe Run and the Guarantors, respectively, and PARI PASSU with all other existing and future unsubordinated indebtedness of Doe Run and the Guarantors. However, holders of secured indebtedness of Doe Run and the Guarantors will have claims that effectively rank prior to those of the Holders with respect to the assets securing such indebtedness. Notwithstanding the foregoing, the indebtedness of Doe Run Peru evidenced by its Guarantee will be contractually subordinated to the indebtedness under the Peruvian Revolving Credit Facility. In addition, except as described in the preceding sentence, the indebtedness of Doe Run Mining and Doe Run Peru evidenced by their Guarantee rank senior in right of payment to all future unsecured indebtedness of Doe Run Mining and Doe Run Peru, respectively, subject to statutorily preferred exceptions and statutorily 108 mandated priorities based on the date of issuance with respect to payment of obligations under applicable Peruvian law. CERTAIN COVENANTS The Indenture contains, among others, the following covenants: LIMITATION ON INDEBTEDNESS (a) Doe Run will not, and will not cause or permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, become liable, contingently or otherwise, with respect to, or otherwise become responsible for the payment of (collectively "incur") any Indebtedness (including Acquired Indebtedness) other than Permitted Indebtedness; PROVIDED that Doe Run and the Guarantors may incur Indebtedness (including Acquired Indebtedness) if: (A) no Default or Event of Default shall have occurred and be continuing at the time of the proposed incurrence thereof or shall occur as a result of such proposed incurrence, and (B) after giving effect to such proposed incurrence, the Consolidated Fixed Charge Coverage Ratio of Doe Run is at least equal to 2.25 to 1.0. Notwithstanding the foregoing, a Restricted Subsidiary that is not a Guarantor may incur Acquired Indebtedness to the extent such Indebtedness could have been incurred by Doe Run and the Guarantors pursuant to the proviso in the immediately preceding sentence. (b) Doe Run and the Guarantors shall not, directly or indirectly, in any event incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated to any other Indebtedness of Doe Run or such Guarantor unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinated to the Notes or the Guarantee of such Guarantor, as the case may be, to the same extent and in the same manner as such Indebtedness is subordinated to such other Indebtedness of Doe Run or such Guarantor. LIMITATION ON RESTRICTED PAYMENTS Doe Run will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, after the Issue Date (a) declare or pay any dividend or make any distribution on Doe Run's Capital Stock or make any payment to holders of such Capital Stock (other than dividends or distributions payable in Qualified Capital Stock of Doe Run), (b) purchase, redeem or otherwise acquire or retire for value any Capital Stock of Doe Run or any warrants, rights or options to purchase or acquire shares of any class of such Capital Stock, (c) purchase, redeem, prepay, defease or otherwise acquire or retire for value, prior to any scheduled maturity, scheduled repayment or scheduled sinking fund payment, Indebtedness of Doe Run or any of the Guarantors that is expressly subordinate in right of payment to the Notes or the Guarantee of such Guarantor, as the case may be, or (d) make any Investment (excluding any Permitted Investment) (each of the foregoing actions set forth in clauses (a), (b), (c) and (d) being referred to as a "Restricted Payment"), if at the time of such Restricted Payment or immediately after giving effect thereto, (i) a Default or an Event of Default shall have occurred and be continuing or (ii) Restricted Payments made subsequent to the Issue Date (the amount expended for such purposes, if other than in cash, shall be the Fair Market Value of such property proposed to be transferred by Doe Run or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment) shall exceed the sum of: (w) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss) of Doe Run earned subsequent to the Issue Date and prior to the date the Restricted Payment occurs (treating such period as a single accounting period); (x) 100% of the aggregate net proceeds, including the Fair Market Value of property other than cash, received by Doe Run from any person (other than a Subsidiary of Doe Run) from the issuance and sale subsequent to the Issue Date of Qualified Capital Stock of Doe Run (excluding (A) Qualified Capital Stock paid as a dividend on any Capital Stock or as interest on any Indebtedness, (B) any net 109 proceeds from issuances and sales financed directly or indirectly using funds borrowed from Doe Run or any Subsidiary of Doe Run, until and to the extent such borrowing is repaid and (C) any net proceeds from any Equity Offering which are used to redeem Fixed Rate Notes pursuant to, and in accordance with, the provisions described under the caption "--Optional Redemption--Optional Redemption upon of Fixed Rate Notes Equity Offerings" above); (y) 100% of the aggregate net proceeds, including the Fair Market Value of property other than cash, received by Doe Run from any person (other than a Subsidiary of Doe Run) from the issuance and sale of Disqualified Capital Stock and/or Indebtedness, in each case that has been converted into or exchanged for Qualified Capital Stock of Doe Run after the Issue Date; and (z) without duplication, the sum of (1) the aggregate amount returned in cash on or with respect to Investments (other than Permitted Investments) made subsequent to the Issue Date whether through interest payments, principal payments, dividends or other distributions or payments, (2) the net cash proceeds received by Doe Run or any Restricted Subsidiary from the disposition of all or any portion of such Investments (other than to a Subsidiary of Doe Run) and (3) upon redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, the Fair Market Value of such Subsidiary; PROVIDED, HOWEVER, that the sum of clauses (1),(2) and (3) above shall not exceed the aggregate amount of all such Investments made subsequent to the Issue Date.

In determining the aggregate amount of Restricted Payments permissible under clause (ii) of the first paragraph of this section, amounts expended, incurred or outstanding pursuant to clauses (1) and (2) (but not pursuant to clauses (3), (4), (5), (6) or (7)) of the second paragraph of this section shall be included as Restricted Payments; PROVIDED that any proceeds received from the issuance of Qualified Capital Stock pursuant to clause (2) of the second paragraph of this section shall be included in calculating the amount referred to in clause (x) or clause (y), as the case may be, of the first paragraph of this section. LIMITATION ON SALE OF ASSETS Doe Run will not, and will not permit any of the Restricted Subsidiaries to, consummate any Asset Sale unless (i) such Asset Sale is for at least Fair Market Value, (ii) at least 80% of the consideration therefrom received by Doe Run or such Restricted Subsidiary is in the form of cash or Cash Equivalents and (iii) Doe Run or such Restricted Subsidiary shall apply the Net Cash Proceeds of such Asset Sale within 270 days of receipt thereof, as follows: (a) first, to repay (and, in the case of any revolving credit facility, effect a permanent reduction in the commitment thereunder) any Indebtedness secured by the assets involved in such Asset Sale or otherwise required to be repaid with the proceeds thereof; and (b) second, with respect to any Net Cash Proceeds remaining after application pursuant to the preceding paragraph (a) (the "Available Amount"), Doe Run shall make an offer to purchase (the "Asset Sale Offer") from all Holders of Notes, up to a maximum principal amount (expressed as a multiple of $1,000) of Notes equal to the Available Amount at a purchase price equal to 100% of the principal amount thereof plus accrued and unpaid interest thereon, if any, to the date of purchase; PROVIDED, HOWEVER, that Doe Run will not be required to apply pursuant to this paragraph (b) Net Cash Proceeds received from any Asset Sale if, and only to the extent that, such Net Cash Proceeds are applied to a Related Business Investment within 270 days of such Asset Sale; PROVIDED, FURTHER, that if at any time any non-cash consideration received by Doe Run or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash, then such conversion or disposition shall be deemed to constitute an Asset Sale under the Indenture and the Net Cash Proceeds thereof shall be applied in accordance with this "Limitation on Sale of Assets" covenant; and PROVIDED, FURTHER, that Doe Run may defer the Asset Sale Offer until there is an aggregate unutilized Available Amount equal to or in excess of $5 million resulting from one or more Asset Sales (at which time, the entire unutilized Available Amount, and not just the amount in excess of $5 million, shall be applied as required pursuant to this paragraph). To the extent the Asset Sale Offer is not fully subscribed to by Holders of the Notes, Doe Run and the Restricted Subsidiaries may retain such unutilized portion of the Available Amount and use it for any purpose not prohibited by the Indenture. 111 In the event of the transfer of substantially all (but not all) of the property and assets of Doe Run and the Restricted Subsidiaries as an entirety to a person in a transaction permitted under "--Merger, Consolidation, Etc." below, the successor corporation shall be deemed to have sold the properties and assets of Doe Run and the Restricted Subsidiaries not so transferred for purposes of this covenant, and shall comply with the provisions of this covenant with respect to such deemed sale as if it were an Asset Sale. In addition, the Fair Market Value of such properties and assets of Doe Run or the Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this covenant. Notice of an Asset Sale Offer will be mailed to the record Holders as shown on the register of Holders not less than 30 days nor more than 60 days before the payment date for the Asset Sale Offer, with a copy to the Trustee, and shall comply with the procedures set forth in the Indenture. Upon receiving notice of the Asset Sale Offer, Holders may elect to tender their Notes in whole or in part in integral multiples of $1,000 principal amount at maturity in exchange for cash. To the extent Holders properly tender Notes in an amount exceeding the Available Amount, Notes of tendering Holders will be repurchased on a PRO RATA basis (based on amounts tendered). An Asset Sale Offer shall remain open for a period of 20 business days or such longer period as may be required by law. If an offer is made to repurchase the Notes pursuant to an Asset Sale Offer, Doe Run will comply with all tender offer rules under state and Federal securities laws, including, but not limited to, Section 14(e) under the Exchange Act and Rule 14e-1 thereunder, to the extent applicable to such offer. CHANGE OF CONTROL Upon the occurrence of a Change of Control, Doe Run shall be obligated to make an offer to purchase (a "Change of Control Offer"), and shall, subject to the provisions described below, purchase, on a business day (the "Change of Control Purchase Date") not more than 60 nor less than 45 days following the occurrence of the Change of Control, all of the then outstanding Notes at a purchase price (the "Change of Control Purchase Price") equal to 101% of the principal amount of the Notes plus accrued and unpaid interest thereon to the date of purchase. Doe Run shall, subject to the provisions described below, be required to purchase all Notes validly tendered into the Change of Control Offer and not withdrawn. The Change of Control Offer is required to remain open for at least 20 business days and until the close of business on the Change of Control Purchase Date. In order to effect such Change of Control Offer, Doe Run shall, not later than the 30th day after the Change of Control, mail to each Holder of Notes notice of the Change of Control Offer, which notice shall govern the terms of the Change of Control Offer and shall state, among other things, the procedures that Holders of Notes must follow to accept the Change of Control Offer. If a Change of Control Offer is made, there can be no assurance that Doe Run will have available funds sufficient to pay the Change of Control Purchase Price for all of the Notes that might be delivered by Holders of Notes seeking to accept the Change of Control Offer. Doe Run shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements applicable to a Change of Control Offer made by Doe Run and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. In the event that a Change of Control occurs and Doe Run is required to purchase the Notes as described above, Doe Run will comply with all tender offer rules under state and Federal securities laws, including, but not limited to, Section 14(e) under the Exchange Act and Rule 14e-1 thereunder, to the extent applicable to such offer. LIMITATION ON LIENS Doe Run will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Liens upon any properties or assets of Doe Run (including, without limitation, any Capital Stock of a Restricted Subsidiary) or any of the Restricted Subsidiaries whether owned on the Issue Date or acquired after the Issue Date, or on any income or profits therefrom, 112 or assign or otherwise convey any right to receive income or profits thereon other than (i) Liens existing on the Issue Date to the extent and in the manner such Liens are in effect on the Issue Date, (ii) Liens on the non-fixed assets of Doe Run and the Restricted Subsidiaries securing Indebtedness under the Revolving Credit Facilities and (iii) Permitted Liens. LIMITATION ON DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED SUBSIDIARIES Doe Run will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to: (a) pay dividends or make any other distributions on its Capital Stock, or any other interest or participation in, or measured by, its profits, owned by Doe Run or by any Restricted Subsidiary, or pay any Indebtedness owed to Doe Run or any Restricted Subsidiary; (b) make loans or advances to Doe Run or any Restricted Subsidiary; or (c) transfer any of its properties or assets to Doe Run or to any Restricted Subsidiary, except for such encumbrances or restrictions existing under or by reason of: (i) applicable law; (ii) the Indenture; (iii) customary non-assignment provisions of any lease governing a leasehold interest of Doe Run or any Restricted Subsidiary; (iv) any instrument governing Indebtedness of a person acquired by Doe Run or any Restricted Subsidiary at the time of such acquisition, which encumbrance or restriction is not applicable to any person, or the properties or assets of any person, other than the person or its Subsidiaries so acquired; (v) any written agreement existing on the Issue Date or amendments or modifications thereto, PROVIDED that no such agreement shall be modified or amended in such a manner as to make the encumbrance or restriction more restrictive than as in effect on the Issue Date; (vi) Indebtedness existing and as in effect on the Issue Date, including, without limitation, the U.S. Revolving Credit Facility or any refinancing, refunding, replacement or extensions thereof, PROVIDED that any such encumbrance or restriction contained in any refinancing, refunding, replacement or extension of the U.S. Revolving Credit Facility shall be no more restrictive than such encumbrance or restriction contained in the U.S. Revolving Credit Facility as in effect on the Issue Date; (vii) Indebtedness under the Peruvian Revolving Credit Facility or any refinancings, refundings, replacements or extensions thereof, PROVIDED that such restrictions do not prohibit payments pursuant to the intercompany agreements between Doe Run and the Restricted Subsidiaries as in effect on the Issue Date or pursuant to any replacements thereof or pursuant to any comparable agreements thereto, in each case providing for the same or similar payments; and (viii) Indebtedness incurred in accordance with the Indenture, PROVIDED that such encumbrance or restriction shall be no more restrictive than any encumbrance or restriction contained in the Revolving Credit Facilities. LIMITATION ON SALE/LEASEBACK TRANSACTIONS Doe Run will not, and will not permit any of the Restricted Subsidiaries to, enter into any Sale/ leaseback. Notwithstanding the foregoing, Doe Run and the Restricted Subsidiaries may enter into a Sale/ leaseback if (i) after giving pro forma effect to any such Sale/leaseback, Doe Run and the Restricted Subsidiaries shall be in compliance with the "Limitation on Indebtedness" covenant described above, (ii) the sale price in such Sale/leaseback is at least equal to the Fair Market Value of such property and (iii) Doe Run or such Restricted Subsidiary shall apply the Net Cash Proceeds of the sale as provided under "Limitation on Sale of Assets" above, to the extent required by such covenant. LIMITATION ON TRANSACTIONS WITH AFFILIATES (a) Doe Run will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any transaction (including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of any service) with or for the benefit of an Affiliate of Doe Run or any Restricted Subsidiary (other than transactions between Doe Run and a Wholly-Owned Restricted Subsidiary or between Wholly-Owned Restricted Subsidiaries) (an "Affiliate Transaction"), other than (x) Affiliate Transactions permitted under (b) below and (y) Affiliate Transactions (including lease transactions) on terms that are no less favorable to Doe Run or the relevant Restricted Subsidiary in the aggregate than those that might reasonably have been obtained in a comparable transaction by Doe Run or 113 such Restricted Subsidiary on an arm's-length basis (as determined in good faith by the Board of Directors of Doe Run, as evidenced by a Board Resolution) from a person that is not an Affiliate; PROVIDED that except as otherwise provided under (b) below, neither Doe Run nor any of the Restricted Subsidiaries shall enter into an Affiliate Transaction or series of related Affiliate Transactions involving or having a value of more than $5.0 million unless Doe Run or such Restricted Subsidiary, as the case may be, has received an opinion from an Independent Financial Advisor, with a copy thereof to the Trustee, to the effect that the financial terms of such Affiliate Transaction are fair and reasonable to Doe Run or such Restricted Subsidiary, as the case may be, and such terms are no less favorable to Doe Run or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable transaction on an arm's-length basis with a person that is not an Affiliate. (b) The foregoing provisions shall not apply to (i) any Restricted Payment that is made in compliance with the covenant entitled "Limitation on Restricted Payments," (ii) payments by Doe Run or any of the Restricted Subsidiaries to Renco or DRA of the amounts set forth in clauses (4), (5), (6) and (7) of the second paragraph of the covenant entitled "Limitation on Restricted Payments" and (iii) reasonable and customary regular fees to directors of Doe Run and the Restricted Subsidiaries who are not employees of Doe Run and the Restricted Subsidiaries. LIMITATION ON PREFERRED STOCK OF RESTRICTED SUBSIDIARIES Doe Run will not permit any Restricted Subsidiary to issue any Preferred Stock (except to Doe Run or a Wholly-Owned Restricted Subsidiary), nor will Doe Run permit any person (other than Doe Run or a Wholly-Owned Restricted Subsidiary) to hold any Preferred Stock of a Restricted Subsidiary. QUALIFYING INVESTMENT REQUIREMENTS At least semi-annually commencing April 30, 1998 until $120 million has been expended by Doe Run Peru in the manner required by Section 4.5 of the Subscription Agreement, (i) Doe Run Peru shall make Investments in Doe Run Mining, which Investments, including any interest payable thereon, shall be represented by promissory notes (the "Qualifying Investments Promissory Notes"), in an amount equal to Doe Run Peru's expected Qualifying Investments for the following six months and (ii) Doe Run Mining shall use the proceeds of each such Qualifying Investment to prepay in part the promissory note issued by Doe Run Mining to Metaloroya on October 23, 1997, the date of consummation of the Acquisition; PROVIDED, FURTHER, that pending utilization of such proceeds for Qualifying Investments, Doe Run Peru may repay outstanding loans under the Peruvian Revolving Credit Facility. FUTURE GUARANTEES If Doe Run or any of the Restricted Subsidiaries transfers or causes to be transferred, in one transaction or a series of related transactions, any property to any Restricted Subsidiary that is not a Guarantor, or if Doe Run or any of the Restricted Subsidiaries shall organize, acquire or otherwise invest in another Restricted Subsidiary, in each case having total assets with a book value in excess of $1 million, then such transferee or acquired or other Restricted Subsidiary shall (i) execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally guarantee all of Doe Run's obligations under the Notes and the Indenture on the terms set forth in the Indenture and (ii) deliver to the Trustee an Opinion of Counsel that such supplemental indenture has been duly authorized, executed and delivered by such Restricted Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Restricted Subsidiary. Thereafter, such Restricted Subsidiary shall be a Guarantor for all purposes of the Indenture. Notwithstanding the foregoing, the following Restricted Subsidiaries shall not be required to become Guarantors under the Indenture: (i) DR Exploration; (ii) any Restricted Subsidiary formed or acquired in connection with Related Business Investments made by Doe Run or any of the Restricted Subsidiaries pursuant to clause (iii) of the definition of "Permitted Investment"; and (iii) any Restricted Subsidiary which is not permitted by law to become a Guarantor under the Indenture. 114 CONDUCT OF BUSINESS Doe Run and the Restricted Subsidiaries will not engage in any businesses which are not the same, similar or reasonably related to the businesses in which Doe Run and the Restricted Subsidiaries are engaged on the Issue Date. REPORTS So long as any Note is outstanding, Doe Run will file with the Commission and, within 15 days after it files them with the Commission, file with the Trustee and mail or cause the Trustee to mail to the Holders at their addresses as set forth in the register of the Notes copies of the annual reports on Form 10-K and of the information, documents and other reports which Doe Run is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or which Doe Run would be required to file with the Commission if Doe Run then had a class of securities registered under the Exchange Act. Such financial information shall include annual reports containing consolidated financial statements and notes thereto, together with an opinion thereon expressed by an independent public accounting firm, management's discussion and analysis of financial condition and results of operations as well as quarterly reports containing unaudited condensed consolidated financial statements for the first three quarters of every fiscal year. MERGER, CONSOLIDATION, ETC. Doe Run will not, in a single transaction or series of related transactions, consolidate or merge with or into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its assets to, any person or adopt a Plan of Liquidation unless: (i) either (1) Doe Run shall be the surviving or continuing corporation or (2) the person (if other than Doe Run) formed by such consolidation or the person into which Doe Run is merged or the person which acquires by sale, assignment, transfer, lease, conveyance or otherwise all or substantially all of the assets of Doe Run or in the case of a Plan of Liquidation, the person to which assets of Doe Run have been transferred (x) shall be a corporation organized and validly existing under the laws of the United States or any State thereof or the District of Columbia and (y) shall expressly assume, by supplemental indenture (in form and substance satisfactory to the Trustee), executed and delivered to the Trustee, the due and punctual payment of the principal of, and premium, if any, and interest on, all of the Notes, and the performance of every covenant of the Indenture, the Notes and the Registration Rights Agreement on the part of Doe Run to be performed or observed; (ii) immediately after giving effect to such transaction and the assumption contemplated by clause (y) above (including giving effect to any Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred in connection with or in respect of such transaction), Doe Run (in the case of clause (1) of the foregoing clause (i)) or such person (in the case of clause (2) thereof) (a) shall have a Consolidated Net Worth (immediately after the transaction but prior to any purchase accounting adjustments relating to such transaction) equal to or greater than the Consolidated Net Worth of Doe Run immediately prior to such transaction and (b) shall be able to incur (assuming a market rate of interest with respect thereto) at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) as if it were Doe Run under paragraph (a) of "--Certain Covenants--Limitation on Indebtedness" above; (iii) immediately before and after giving effect to such transaction and the assumption contemplated by clause (y) above (including giving effect to any Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred in connection with or in respect of the transaction), no Default or Event of Default shall have occurred or be continuing; (iv) Doe Run or such person shall have delivered to the Trustee (A) an Officers' Certificate and an Opinion of Counsel (which counsel shall not be in-house counsel of Doe Run) each stating that such consolidation, merger, conveyance, transfer or lease or Plan of Liquidation and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this provision of the Indenture and that all conditions precedent in the Indenture relating to such transaction have been satisfied and (B) a certificate from Doe Run's independent certified public accountants stating that Doe Run has made the calculations required by clause (ii) above in accordance with the terms of the Indenture; and (v) neither Doe Run nor any Restricted Subsidiary nor such person, as the case may be, 115 would thereupon become obligated with respect to any Indebtedness (including Acquired Indebtedness), nor any of its property or assets subject to any Lien, unless Doe Run or such Restricted Subsidiary or such person, as the case may be, could incur such Indebtedness (including Acquired Indebtedness) or create such Lien under the Indenture (giving effect to such person being bound by all the terms of the Indenture). Notwithstanding the foregoing, (i) the merger of Doe Run with an Affiliate incorporated solely for the purpose of incorporating Doe Run in another jurisdiction shall be permitted and (ii) the merger of Doe Run and any Restricted Subsidiary shall be permitted. For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries, the Capital Stock of which constitutes all or substantially all of the properties and assets of Doe Run, shall be deemed to be the transfer of all or substantially all of the properties and assets of Doe Run. Each Guarantor (other than any Guarantor whose Guarantee is to be released in accordance with the terms of the Guarantee and the Indenture in connection with any transaction complying with the provisions of "--Limitation on Sale of Assets") will not, and Doe Run will not cause or permit any Guarantor to, consolidate with or merge with or into or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its assets to any person (other than a merger of Doe Run with any Guarantor or a merger of Guarantors) unless: (i) the entity formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, lease, conveyance or other disposition shall have been made is a corporation organized and validly existing under the laws of the United States or any state thereof or the District of Columbia or an entity organized and validly existing under the laws of the foreign jurisdiction in which such Guarantor is organized; (ii) such entity assumes by supplemental indenture all of the obligations of such Guarantor under such Guarantee; and (iii) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing. Upon any such consolidation, merger, conveyance, lease or transfer in accordance with the foregoing, the successor person formed by such consolidation or into which Doe Run or any other Guarantor, as the case may be, is merged or to which such conveyance, lease or transfer is made will succeed to, and be substituted for, and may exercise every right and power of, Doe Run or such Guarantor, as the case may be, under the Indenture with the same effect as if such successor had been named as Doe Run or such Guarantor, as the case may be, therein, and thereafter (except in the case of a sale, assignment, transfer, lease, conveyance or other disposition) the predecessor corporation will be relieved of all further obligations and covenants under the Indenture and the Notes, in the case of Doe Run, or its Guarantee, in the case of any Guarantor. EVENTS OF DEFAULT The following are Events of Default under the Indenture: (a) Doe Run defaults in the payment of interest on the Notes when the same becomes due and payable and the Default continues for a period of 30 days; (b) Doe Run defaults in the payment of the stated principal amount of the Notes when the same becomes due and payable at maturity, upon acceleration or redemption pursuant to an offer to purchase required under the Indenture or otherwise; (c) Doe Run or any of the Guarantors fails to comply in all material respects with any of their other agreements contained in the Notes or the Indenture (including, without limitation, under the provisions of "--Certain Covenants--Change of Control," "--Certain Covenants--Limitation on Sale of Assets" and "--Merger, Consolidation, Etc."), and the Default continues for the period and after the notice specified below; (d) there shall be any default or defaults in the payment of principal or interest under one or more agreements, instruments, mortgages, bonds, debentures or other evidences of Indebtedness 116 under which Doe Run or any Restricted Subsidiary then has outstanding Indebtedness in excess of $7.5 million, individually or in the aggregate; (e) there shall be any default or defaults under one or more agreements, instruments, mortgages, bonds, debentures or other evidences of Indebtedness under which Doe Run or any Restricted Subsidiary then has outstanding Indebtedness in excess of $7.5 million, individually or in the aggregate, and such default or defaults have resulted in the acceleration of the maturity of such Indebtedness; (f) Doe Run or any of the Restricted Subsidiaries fails to perform (after giving effect to any applicable grace periods) any term, covenant, condition or provision of one or more agreements, instruments, mortgages, bonds, debentures or other evidences of Indebtedness under which Doe Run or any of the Restricted Subsidiaries then has outstanding Indebtedness in excess of $7.5 million, individually or in the aggregate, and such failure to perform results in the commencement of judicial proceedings to foreclose upon any assets of Doe Run or any of the Restricted Subsidiaries securing such Indebtedness or the holders of such Indebtedness shall have exercised any right under applicable law or applicable security documents to take ownership of any such assets in lieu of foreclosure; (g) one or more judgments, orders or decrees for the payment of money which either individually or in the aggregate at any one time exceed $7.5 million shall be rendered against Doe Run or any of the Restricted Subsidiaries by a court of competent jurisdiction and shall remain undischarged and unbonded for a period (during which execution shall not be effectively stayed) of 60 consecutive days after such judgment becomes final and nonappealable; (h) Doe Run or any Significant Subsidiary (1) admits in writing its inability to pay its debts generally as they become due, (2) commences a voluntary case or proceeding under any Bankruptcy Law with respect to itself, (3) consents to the entry of a judgment, decree or order for relief against it in an involuntary case or proceeding under any Bankruptcy Law, (4) consents to the appointment of a Custodian of it or for substantially all of its property, (5) consents to or acquiesces in the institution of a bankruptcy or an insolvency proceeding against it, (6) makes a general assignment for the benefit of its creditors or (7) takes any corporate action to authorize or effect any of the foregoing; (i) a court of competent jurisdiction enters a judgment, decree or order for relief in respect of Doe Run or any Significant Subsidiary in an involuntary case or proceeding under any Bankruptcy Law which shall (1) approve as properly filed a petition seeking reorganization, arrangement, adjustment or composition in respect of Doe Run or any Significant Subsidiary, (2) appoint a Custodian of Doe Run or any Significant Subsidiary or for substantially all of its property or (3) order the winding-up or liquidation of its affairs, and such judgment, decree or order shall remain unstayed and in effect for a period of 60 consecutive days; or (j) any of the Guarantees of any Significant Subsidiary ceases to be in full force and effect or any of such Guarantees is declared to be null and void and unenforceable or any of such Guarantees is found to be invalid or, any such Guarantor denies its liability under its Guarantee (other than by reason of release of a Guarantor in accordance with the terms of the Indenture). A Default under clause (c) above (other than in the case of any Default under the provisions of "--Certain Covenants--Limitation on Sale of Assets," "--Certain Covenants--Change of Control" or "--Merger, Consolidation, Etc.," which Defaults shall be Events of Default without the notice and without the passage of time specified in this paragraph) is not an Event of Default until the Trustee notifies Doe Run, or the Holders of at least 25% in principal amount of the outstanding Notes notify Doe Run and the Trustee, of the Default and Doe Run does not cure the Default within 30 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a "Notice of Default." Such notice shall be given by the Trustee if so requested by the Holders of at least 25% in principal amount of the Notes then outstanding. If an Event of Default (other than an Event of Default specified in clause (h) or (i) above) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate 117 principal amount of the then outstanding Notes may declare the unpaid principal of, premium, if any, and accrued and unpaid interest on, all the Notes then outstanding to be due and payable, by a notice in writing to Doe Run (and to the Trustee, if given by Holders) and upon such declaration such principal amount, premium, if any, and accrued and unpaid interest will become immediately due and payable, notwithstanding anything contained in the Indenture or the Notes to the contrary. If an Event of Default specified in clause (h) or (i) above occurs, all unpaid principal of, and premium, if any, and accrued and unpaid interest on, the Notes then outstanding will IPSO FACTO become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee reasonable indemnity. Subject to all provisions of the Indenture and applicable law, the Holders of a majority in aggregate principal amount of the then outstanding Notes have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. The Trustee may withhold from Holders notice of any continuing Default or Event of Default (except a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes or that resulted from the failure to comply with the provisions of "--Certain Covenants--Change of Control" or "--Merger, Consolidation, Etc.") if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may rescind an acceleration and its consequences if all existing Events of Default (other than the nonpayment of principal of and premium, if any, and interest on the Notes which has become due solely by virtue of such acceleration) have been cured or waived and if the rescission would not conflict with any judgment or decree. No such rescission shall affect any subsequent Default or impair any right consequent thereto. The Holders of a majority in aggregate principal amount of the Notes then outstanding may, on behalf of the Holders of all the Notes, waive any past Default or Event of Default under the Indenture and its consequences, except a Default in the payment of principal of or premium, if any, or interest on the Notes or in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of all Holders. Under the Indenture, Doe Run is required to provide an Officers' Certificate to the Trustee promptly upon any such officer obtaining knowledge of any Default or Event of Default (provided that such officers shall provide such certification at least annually whether or not they know of any Default or Event of Default) that has occurred and, if applicable, describe such Default or Event of Default and the status thereof. In addition, for each fiscal year, Doe Run's independent certified public accountants are required to certify to the Trustee that they have reviewed the terms of the Indenture and the Notes as they relate to accounting matters and whether, during the course of their audit examination, any Default or Event of Default has come to their attention, and specifying the nature and period of existence of any such Default or Event of Default. AMENDMENT, SUPPLEMENT AND WAIVER From time to time, Doe Run, the Guarantors and the Trustee may, without the consent of the Holders, amend, waive or supplement the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies, maintaining the qualification of the Indenture under the TIA or making any change that does not adversely affect the rights of any Holder. In addition, the Indenture contains provisions permitting Doe Run, the Guarantors and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the then outstanding Notes, to enter into any supplemental indenture for the purpose of adding, changing or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the Holders under the Indenture; PROVIDED that no such supplemental indenture may without the consent of the Holder of each 118 outstanding Note affected thereby: (i) reduce the amount of Notes whose Holders must consent to an amendment or waiver; (ii) reduce the rate of, or extend the time for payment of, interest, including defaulted interest, on any Note; (iii) reduce the principal of or premium on or change the fixed maturity of any Note; (iv) make the principal of, or interest on, any Note payable in money other than as provided for in the Indenture and the Notes; (v) make any change in provisions relating to waivers of defaults, the ability of Holders to enforce their right under the Indenture or in the matters discussed in these clauses (i) through (x); (vi) waive a default in the payment of principal of or interest on, or redemption or repurchase payment with respect to, any Notes, including, without limitation, a failure to make payment when required upon a Change of Control or after an Asset Sale Offer; (vii) adversely affect the ranking of the Notes or the Guarantees in any material respect; (viii) change the Maturity Date or alter the redemption provisions in a manner adverse to Holders; (ix) after Doe Run's obligation to purchase the Notes arises thereunder, amend, modify or change the obligation of Doe Run to make and consummate a Change of Control Offer in the event of a Change of Control or an Asset Sale Offer in the event of an Asset Sale or waive any default in the performance thereof or modify any of the provisions or definitions with respect to any such offers; or (x) release the Guarantee of any Significant Subsidiary.

The foregoing laws and interpretations thereof are subject to change, which could apply retroactively. The exchange of Old Notes for Exchange Notes pursuant to the Exchange Offer will not be a taxable event for federal income tax purposes. A holder's holding period for Exchange Notes will include the holding period for Old Notes. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF EXCHANGING OLD NOTES FOR EXCHANGE NOTES. PLAN OF DISTRIBUTION A broker-dealer that is the holder of Old Notes that were acquired for the account of such broker-dealer as a result of market-making or other trading activities (other than Old Notes acquired directly from Doe Run or any affiliate of Doe Run) may exchange such Old Notes for Exchange Notes pursuant to the Exchange Offer; provided, that each broker-dealer that receives Exchange Notes for its own account in exchange for Old Notes, where such Old Notes were acquired by such broker-dealer as a result of market-making or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Old Notes where such Old Notes were acquired as a result of market-making activities or other trading activities. Doe Run has agreed that for a period of 180 days after consummation of the Exchange Offer, it will make this Prospectus, as it may be amended or supplemented from time to time, available to any broker-dealer for use in connection with any such resale. In addition, until , 1998, all dealers effecting transactions in the Exchange Notes may be required to deliver a prospectus. Doe Run will not receive any proceeds from any sale of Exchange Notes by broker-dealers or any other holder of Exchange Notes. Exchange Notes received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange Notes that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such Exchange Notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of Exchange Notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The Letter of Transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. For a period of 180 days after consummation of the Exchange Offer, Doe Run will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. Doe Run has agreed to pay all expenses incident to the Exchange Offer and to Doe Run's performance of, or compliance with, the Registration Rights Agreement (other than commissions or concessions of any brokers or dealers) and will indemnify the holders of the Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act. 131 LEGAL MATTERS Certain legal matters related to the Exchange Notes being offered hereby are being passed upon for Doe Run and the Guarantors by Cadwalader, Wickersham & Taft, New York, New York.

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We did not audit the consolidated financial statements of Doe Run Cayman Ltd., a wholly-owned subsidiary, which statements reflect total assets constituting 45% and total revenues constituting 1% in 1997, of the related consolidated totals. Those consolidated statements were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for Doe Run Cayman Ltd. and its subsidiaries, is based solely on the reports of the other auditors. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits and the reports of the other auditors provide a reasonable basis for our opinion. In our opinion, based on our audits and the report of the other auditors, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of The Doe Run Resources Corporation and subsidiaries as of October 31, 1996 and 1997, and the results of their operations and their cash flows for each of the years in the three-year period ended October 31, 1997, in conformity with generally accepted accounting principles.

See accompanying notes to consolidated financial statements. F-6 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN THOUSANDS) (1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES PRINCIPLES OF CONSOLIDATION These consolidated financial statements include the accounts of The Doe Run Resources Corporation and its wholly owned subsidiaries (the "Company"). All material intercompany balances and transactions have been eliminated. NATURE OF BUSINESS The principal domestic business of the Company is the exploration, development, mining and processing of base metals, primarily lead, and recycling of lead-acid batteries and other lead-bearing materials. The Company's fabrication businesses fabricate lead products used in radiation and X-ray shielding, pollution control devices, and medical equipment, produce lead oxide for use in automotive batteries, and fabricate and repair lead-lined process equipment. In Peru, the Company is engaged in the smelting and refining of polymetallic concentrates, mainly copper, lead and zinc, which are sold as refined metals primarily to customers located outside of Peru. FOREIGN CURRENCY TRANSLATION The functional currency of the Company's foreign subsidiaries is the U.S. Dollar. Accordingly, translation gains and losses are included in determining net income. USE OF ESTIMATES The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from these estimates. CASH All of the Company's domestic accounts are zero balance accounts. Checks cleared on domestic bank accounts are funded by advances drawn on revolving loans. Cash received from domestic operations is transferred to the Company's primary lender daily and applied to outstanding revolving loans, if any. INVENTORIES Finished metals and concentrates, metals and concentrates in process, and raw materials are stated at the lower of cost or market. The last-in, first-out ("LIFO") method of determining cost is used for the majority of the Company's U.S. inventories. Inventory costs of the Company's foreign subsidiaries are determined using the first-in, first-out ("FIFO") method. Inventory costs include labor, material and other production costs. Supplies and repair parts are principally stated at average cost, net of reserves for obsolescence. F-7 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are recorded at cost. Major additions and improvements to property, plant and equipment are capitalized, at cost, when they significantly increase the productive capacity or the life of the asset. Routine or unanticipated repair and maintenance expenditures, which do not extend the useful life or increase the productive capacity of the asset, are charged to operations as incurred. Major expenditures required to maintain the originally anticipated productive capacity and life of the asset (such as furnace rebuilds), for which both the amount and timing can be reasonably estimated, are accrued and charged to operations over the period through the next anticipated maintenance date. Mineral interests are amortized using the units of production method. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, as follows: 3 to 20 Buildings and improvements.................................... years 2 to 15 Machinery and equipment....................................... years
Facilities at which operations have temporarily ceased may be placed on a standby care and maintenance basis. The Company continues to depreciate the related assets during the standby period, however, the expected useful lives are adjusted. During the standby period all care and maintenance expenditures incurred are expensed. IMPAIRMENT OF LONG-LIVED ASSETS In fiscal 1997, the Company adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." The statement requires that long-lived assets, certain identifiable intangibles and goodwill related to those assets be reviewed for impairment when events or circumstances indicate that the carrying amount of the assets may not be recoverable. The impairment loss on such assets, as well as long-lived assets and certain identifiable intangibles to be disposed of, is measured as the amount by which the carrying value of the assets exceeds the fair value of the assets. No impairment losses have been recognized. DEFERRED FINANCING COSTS Deferred financing costs represent fees paid in conjunction with the acquisition of long-term debt and are amortized using the interest method over the term of the respective debt. EXPLORATION AND DEVELOPMENT COSTS Exploration and development costs incurred to maintain production at operating mines are charged to operations as incurred. Mine development expenditures on new mines and major development expenditures at operating mines that are expected to benefit future production are capitalized and amortized using the units of production method over the estimated proven ore reserves to be benefited. F-8 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) RECLAMATION COSTS The Company's mines and related processing facilities are subject to governance by various agencies that have established minimum standards for reclamation. Company estimates of mine closure costs are accrued and charged to expense using the units of production method during the estimated life of the operations. A reserve for reclamation costs has been established for the restoration of certain abandoned mining and processing sites based on current estimates of the cost to comply with existing standards. Routine environmental expenditures are expensed as incurred or capitalized and depreciated depending on their future economic benefit. COMMITMENTS AND CONTINGENCIES The Company accrues for loss contingencies, including costs associated with environmental remediation obligations, when such costs are probable and reasonably estimable. Accruals are reviewed and adjusted as circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. REVENUE RECOGNITION Sales are recorded as products are shipped to customers. Concentrate and certain smelter product sales are recorded based on estimated weights, metal contents and prices using applicable customer agreements and hedge contracts. All such sales are adjusted when final weights, metal contents and prices are determined. RISK MANAGEMENT The Company's use of derivative financial instruments is limited to managing well-defined commodity price risks related to future production. Derivative financial instruments are not used for trading purposes. The Company may, from time to time, enter into forward physical sales agreements with customers or futures contracts, which fix prices for a portion of its anticipated future production, generally for periods not exceeding twelve months. The Company may also periodically buy futures contracts to offset the effect of certain fixed-price forward physical sales commitments. In addition, the Company may employ the use of commodity options to obtain the aforementioned transactions. Since these transactions meet the requirements for hedge accounting, gains and losses realized on such transactions, as well as any cost or revenue associated therewith, are recognized in net sales when the related production is sold. If an instrument does not meet the requirements for hedge accounting, gains and losses are recognized immediately. FAIR VALUE OF FINANCIAL INSTRUMENTS The fair values of the Company's long-term debt were estimated using discounted cash flow analyses, based on the estimates of incremental borrowing rates for similar types of borrowing arrangements. At October 31, 1996 and 1997, the fair values of the Company's financial instruments, except for the hedge positions described in Note 13, were not materially different from their carrying amounts. F-9 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) RESEARCH AND DEVELOPMENT Research and development costs are expensed when incurred and are included in selling, general and administrative expenses on the consolidated statements of operations. Research and development costs are not significant. INCOME TAXES Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. UNAUDITED INTERIM FINANCIAL STATEMENTS In the opinion of management, the interim consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary to present fairly the consolidated financial position and results of operations for the periods presented herein. Interim periods are not necessarily indicative of results to be expected for the year (2) BUSINESS ACQUISITION Doe Run Cayman Ltd. ("Doe Run Cayman"), a Cayman Islands corporation and a wholly owned subsidiary of the Company, was incorporated on September 10, 1997. On October 23, 1997, Doe Run Cayman, through its subsidiary Doe Run Peru S.R. Ltda., acquired substantially all of the outstanding shares of Empresa Metalurgica La Oroya S.A. ("Metaloroya"). Metaloroya is a Peruvian corporation, which was formed for purposes of consummating the sale of certain assets and liabilities of La Oroya, a division of Empresa Minera del Centro del Peru S.A., an entity owned by the Peruvian government. Doe Run Cayman's operating subsidiaries in Peru will herein be referred to as "Doe Run Peru." The acquisition was made through a Contract of Stock Transfer, Capital Increase and Stock Subscription (the "Contract"). Peruvian law required a capital contribution to Metaloroya of $126,500 in exchange for 51% of the shares and a payment of $120,515 for the transfer of the remaining 49%. Subsequent to the acquisition, utilizing the proceeds from the capital contribution, Doe Run Peru repaid $125,000 on the $225,000 term loan used to finance the transaction. F-10 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (2) BUSINESS ACQUISITION (CONTINUED) The acquisition has been accounted for as a purchase and the effective purchase price of $123,015, including transaction costs of approximately $2,500, was allocated to the fair value of the assets acquired and liabilities assumed as follows: Inventories....................................................... $ 55,567 Other current assets.............................................. 1,382 Property, plant and equipment..................................... 97,761 Accounts payable and other accrued liabilities.................... (24,495) Environmental contingency......................................... (7,200) --------- $ 123,015 --------- ---------
The excess of the fair value of the net assets acquired over the purchase price, approximately $157,000, reduced the value of the fixed assets acquired. The results of the operations of Doe Run Peru have been included with those of the Company since the date of acquisition. The following unaudited pro forma results of operations for the years ended October 31, 1996 and 1997 assume that the acquisition of Doe Run Peru occurred as of the beginning of the respective periods. The pro forma information does not purport to be indicative of the results of operations that would have occurred had the acquisition occurred at the beginning of the periods presented or of the future results of operations.

(3) RELATED PARTY TRANSACTIONS The Company has entered into a management consulting agreement with The Renco Group, Inc. ("Renco"). Renco holds all of the preferred stock of the Company, and Renco's subsidiary, DR Acquisition Corp. holds all of the Company's common stock. Under the agreement, Renco will provide the Company with management services for a fee of $1,200 annually. The agreement expires October 31, 2000. Fees expensed under this agreement were $1,200 for each of the years ended October 31, 1995, 1996 and 1997. To obtain the advantages of volume, Renco purchases certain categories of property and casualty insurance for a number of its subsidiaries, including the Company, and the actual cost of such insurance, without markup, is reimbursed by the covered subsidiaries. For the years ended October 31, 1995, 1996 and 1997 the Company reimbursed Renco for costs of approximately $1,754, $1,821 and $2,473 respectively, under the Renco insurance program. F-11 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (4) INVENTORIES Inventories consist of the following:

Materials, supplies and repair parts are stated net of reserves for obsolescence of $4,866, $4,977 and $4,738 at October 31, 1996 and 1997 and January 31, 1998, respectively. The FIFO cost of inventories valued under the LIFO cost method were $19,508 and $20,311 at October 31, 1996 and 1997, respectively. If the FIFO cost method had been used to determine cost, inventories would have been $3,242 and $5,996 higher at October 31, 1996 and 1997, respectively. As a result of reducing certain inventory quantities valued on the LIFO basis, lower inventory costs prevailing in previous years were charged to cost of sales in 1995, 1996 and 1997. In 1996, the Company adopted a policy of calculating the effect of LIFO liquidations on net income based on the current cost method. The effect was an increase in net income of $111, $542, and $899 for the years ended October 31, 1995, 1996 and 1997, respectively.

On October 23, 1997 the Company and Doe Run Peru borrowed $130,000 and $225,000, respectively, under credit agreements with a group of financial institutions. The proceeds were used to retire all of the Company's outstanding debt, except for the Pollution Control Bonds, and to finance the acquisition and capital contribution discussed in Note 2. The applicable interest rate on the loans is the greater of the Eurodollar rate (adjusted for the maximum reserve percentages as established by the Federal Reserve Board) or the ten-year U.S. Treasury bond rate, plus an applicable margin: 2.5%, to increase 0.25% per quarter on the $130,000 loan and 3%, to increase .25% annually, on the $225,000 loan. The credit agreements also provided for borrowing under two credit facilities. The first facility allows the Company to borrow up to $100,000 and expires October 23, 2002. The availability of funds under the F-15 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (7) LONG-TERM DEBT (CONTINUED) facility is limited to a percentage of eligible accounts receivable and inventories. Actual availability was $40,417 at October 31, 1997. The facility bears interest at a base rate plus an applicable margin. The base rate is equal to the greater of 1) the adjusted certificate of deposit rate plus .5%, 2) the financial institutions' prime lending rate, or 3) the Federal funds rate plus .5%; or the adjusted Eurodollar rate as specified by the Company. The applicable margin is 2.5%, or .75% in the case of Eurodollar rate loans. The Company is also obligated to pay an unused line fee equal to .375% on the amount by which the maximum credit of $100,000 exceeds outstanding loans and letters of credit. All cash received from the Company's domestic operations is wired daily to the financial institutions to pay down the outstanding loan balance, if any. Revolving loans and standby letters of credit outstanding under this facility were $0 and $6,100, respectively, at October 31, 1997. The second facility allows Doe Run Peru to borrow up to $50,000 and expires October 23, 2002. The interest rate is due to increase .25% annually. An unused line fee of .5% per annum on the average unused portion of the line is payable quarterly, in arrears. Availability of funds under the facility is limited to a percentage of eligible accounts receivable and inventories. Actual availability was $29,332 at October 31, 1997. Revolving loans and standby letters of credit outstanding under this facility were $3,000 and $3,300, respectively, at October 31, 1997. Pollution control financing represents the outstanding balances of revenue bonds issued to provide funding for pollution control facilities at the Company's domestic primary lead smelter. The debt is guaranteed by the former owner of the Company. Effective January 31, 1997, the Company amended the terms of the revolving and term loans dated April 7, 1994. The amendment reduced the interest rate payable, increased the amount of the term loan, and extended the term of the revolving and term loans, which were due to mature April 7, 1997 and April 7, 1998, respectively. Pursuant to the amendment, the Company borrowed an additional $10,945 on the term loan, for a new principal balance of $15,000, due in monthly installments, maturing January 2002. The proceeds were used to retire the senior note balance of $9,172 on January 31, 1997 and pay contingent interest of $1,426. These loans were retired with the proceeds of the $130,000 term loan as discussed above. Virtually all of the Company's assets are pledged to secure long-term debt. In conjunction with early extinguishments of long-term debt in 1997, the Company recognized extraordinary charges of $1,062, net of income tax benefit of $265. The aggregate estimated amounts of long-term debt maturing after October 31, 1997 are as follows: 1998.............................................................. $ 12,345 1999.............................................................. 21,395 2000.............................................................. 35,500 2001.............................................................. 33,500 2002.............................................................. 72,000 Thereafter........................................................ 60,000 --------- $ 234,740 --------- ---------
F-16 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (7) LONG-TERM DEBT (CONTINUED) In addition to scheduled principal payments on the term loans, additional payments may be required based on cash flow for the previous fiscal year, beginning with the year ended October 31, 1998. The Company's various debt agreements contain certain requirements with respect to net worth, leverage ratios, and coverage of fixed charges, which begin in fiscal 1998. These agreements also place limitations on dividend payments and other outside borrowings and restrict annual capital expenditures. The Company was in compliance with all debt covenants at October 31, 1997, and accordingly, the related debt is classified as long-term. As of January 31, 1998, the Company had received waivers from its lenders with respect to the net worth and leverage ratio requirements under the $130,000 term loan and revolving loan under the $100,000 credit facility. The waivers are effective for the quarter ended January 31, 1998 with respect to the leverage ratio requirements and for the two quarters ending April 30, 1998 with respect to the net worth requirements. The Company refinanced all of the loans outstanding under the credit agreements during the quarter ending April 30, 1998. (8) INCOME TAXES The Company files a consolidated federal income tax return with Renco. Pursuant to a tax sharing agreement with Renco, the Company provides for federal income taxes as if the Company filed separate income tax returns except that, generally, no carryforward of net operating losses is permitted, unless such losses are generated by net tax temporary differences. Under the terms of the agreement, the Company is required to remit annually to Renco the amount of federal income taxes provided. Renco files the Company's state income tax returns, and the Company remits the resulting tax to Renco. Doe Run Peru and its subsidiaries pay taxes directly to their respective jurisdictions in which income and other similar taxes arise. Doe Run Cayman is subject to the regulations of the Cayman Islands, which currently have no corporate income or capital gains tax. Doe Run Cayman's subsidiaries located in Peru are subject to Peruvian taxation. The statutory income tax rate in Peru is 30%. Doe Run Peru is subject to a ten-year tax stabilization agreement with the Peruvian government, which provides for Peruvian taxation based on tax statutes and regulations prevailing on October 21, 1997. Metaloroya is subject to a tax stabilization agreement with the Peruvian government, which provides for Peruvian taxation based on tax statutes and regulations prevailing on April 25, 1994. This agreement was modified, and an election was made to adopt the tax statutes and regulations as of November 6, 1997, beginning with the Peruvian tax year ending on December 31, 1997, through December 31, 2006. F-17 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (8) INCOME TAXES (CONTINUED) Income tax expense is comprised of the following:
YEAR ENDED OCTOBER 31, ------------------------------- 1995 1996 1997 --------- --------- --------- Current: Federal........................................................ $ 3,175 $ 6,383 $ 3,882 State.......................................................... 77 68 99 Foreign........................................................ -- -- 419 --------- --------- --------- 3,252 6,451 4,400 Deferred: Foreign........................................................ -- -- (69) --------- --------- --------- $ 3,252 $ 6,451 $ 4,331 --------- --------- --------- --------- --------- ---------
Income tax expense differed from the amount computed by applying the statutory federal corporate income tax rate of 35% to income before income tax expense as a result of the following:
YEAR ENDED OCTOBER 31, ------------------------------- 1995 1996 1997 --------- --------- --------- Income tax expense at statutory rate.......................... $ 2,651 $ 6,620 $ 1,392 Increase (reduction) in income tax expense resulting from: Percentage depletion in excess of basis.....................

F-18 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (8) INCOME TAXES (CONTINUED) The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows:
AS OF OCTOBER 31, ---------------------- 1996 1997 ---------- ---------- Deferred tax assets: Inventories and other current assets................................ $ 364 $ 514 Accrued liabilities................................................. 3,268 3,099 Postretirement benefits............................................. 4,920 4,781 Reclamation and environmental costs................................. 10,278 9,399 Other noncurrent assets and liabilities............................. 11,924 14,346 ---------- ---------- 30,754 32,139 Less valuation allowance............................................ (8,841) (13,328) ---------- ---------- Total deferred tax assets......................................... 21,913 18,811 ---------- ---------- Deferred tax liabilities: Inventories and other current assets................................ (78) -- Property, plant and equipment....................................... (10,883) (11,557) Percentage depletion................................................ (5,136) (4,856) Pension asset....................................................... (2,630) (2,329) Long-term debt...................................................... (3,186) -- ---------- ---------- Total deferred tax liabilities.................................... (21,913) (18,742) ---------- ---------- Net deferred tax assets......................................... $ -- $ 69 ---------- ---------- ---------- ----------
The deferred tax liabilities related to inventories, other current assets and property, plant and equipment are principally due to differences in book and tax allocations of the excess of the fair value of net assets acquired over the purchase price paid. Accruals for financial reporting purposes, which have no tax basis, gave rise to a significant portion of the other temporary differences. The Company recognized a deferred tax asset of $8,451 and $10,188 for an alternative minimum tax carryforward at October 31, 1996 and 1997, respectively, which is included above in other noncurrent assets and liabilities. The alternative minimum tax carryforward is available to reduce future Federal regular income taxes, if any, over an indefinite period. Management has provided a valuation allowance against its net domestic deferred tax assets, since it is unlikely, to the extent deferred tax assets exceed deferred tax liabilities, that the benefits will be realized. F-19 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (9) EMPLOYEE BENEFITS DOMESTIC PLANS DEFINED BENEFIT PLANS The Company sponsors a non-contributory defined benefit plan. Benefits provided to salaried employees under the defined benefit plan are based on final average compensation and years of service. Benefits provided to hourly employees are based on a flat rate and years of service. Net periodic pension expense (income) is comprised of the following:
YEAR ENDED OCTOBER 31, ------------------------------- 1995 1996 1997 --------- --------- --------- Service cost.................................................. $ 865 $ 1,342 $ 1,439 Interest cost on projected benefit obligation................. 3,025 3,506 3,660 Actual return on assets....................................... (5,016) (4,168) (7,306) Net amortization and deferral of unrecognized net losses...... 1,007 176 3,333 --------- --------- --------- Net periodic pension expense (income)......................... $ (119) $ 856 $ 1,126 --------- --------- --------- --------- --------- ---------
The following assumptions were used in the determination of net periodic pension expense (income):
YEAR ENDED OCTOBER 31, ------------------------------- 1995 1996 1997 --------- --------- --------- Discount rates................................................. 9.00% 7.50% 7.75% Rate of increase in compensation levels........................ 3.00 3.00 3.00 Expected long-term rate of return on assets.................... 9.00 9.00 9.00
The following table sets forth the funded status of the Company's defined benefit plan:
AS OF OCTOBER 31, ---------------------- 1996 1997 ---------- ---------- Actuarial present value of benefit obligations: Vested benefit obligation........................................... $ (38,385) $ (43,417) Non-vested obligation............................................... (2,261) (2,758) ---------- ---------- Accumulated benefit obligation.................................... $ (40,646) $ (46,175) ---------- ---------- ---------- ---------- Projected benefit obligation.......................................... $ (46,758) (51,748) Less plan assets at fair value, primarily investments in common stock and corporate bonds................................................. 47,401 51,359 ---------- ---------- Plan assets in excess of projected benefit obligation................. 643 (389) Unrecognized net loss................................................. 6,207 6,457 ---------- ---------- Pension asset, including in other noncurrent assets, net.......... $ 6,850 $ 6,068 ---------- ---------- ---------- ----------
The weighted average discount rate used in determining the projected benefit obligation was 7.75% and 7.5% as of October 31, 1996 and 1997, respectively. The unrecognized net loss is amortized over the average remaining service period of employees expected to receive benefits under the plan. F-20 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (9) EMPLOYEE BENEFITS (CONTINUED) The Company also adopted a supplemental defined benefit plan, The Supplemental Employee Retirement Plan (SERP), effective November 1, 1996. The SERP provides benefits to those participants of the defined benefit plan whose benefits under the plan are limited by Sections 401(a)(17) or 415 of the Internal Revenue Code. Benefits under the SERP represent the amount by which the benefits under the defined benefit plan, if such benefits were not limited, exceed those benefits the participants are entitled to receive. The SERP is unfunded. The Company recorded pension expense of $259 for the year ended October 31, 1997, an intangible pension asset of $624, and a pension liability of $883 at October 31, 1997 with respect to the SERP plan. POSTRETIREMENT BENEFIT PLANS The Company sponsors three postretirement medical plans. The plans generally cover medical expenses subject to deductibles, copayments and limits on specified coverage. For persons retired on or before January 1, 1992, the retiree's contribution to the cost of these plans varies primarily based upon the date of retirement and the respective plan. Effective January 1, 1992, the Company's contribution to the cost of coverage of employees retiring after that date has decreased gradually, until, beginning in 1997, retirees pay 100% of the cost of coverage. The Company maintains stop-loss insurance for claims exceeding $200 per person in any calendar year. The postretirement benefit plans are unfunded. The following illustrates the Company's postretirement benefit obligation:
AS OF OCTOBER 31, -------------------- 1996 1997 --------- --------- Accumulated postretirement benefit obligation: Retirees.............................................................. $ 11,418 $ 10,169 Fully eligible active participants.................................... 171 135 Other actives......................................................... 257 248 --------- --------- 11,846 10,552 Unrecognized net gain................................................... 1,901 2,818 --------- --------- Postretirement benefit obligation..................................... $ 13,747 $ 13,370 --------- --------- --------- ---------
Net periodic postretirement benefit cost includes the following components:
YEAR ENDED OCTOBER 31, ------------------------------- 1995 1996 1997 --------- --------- --------- Service cost........................................................ $ 33 $ 23 $ 34 Interest cost....................................................... 1,076 886 789 Amortization of gains............................................... -- (23) (104) --------- --------- --------- Net periodic postretirement benefit cost.......................... $ 1,109 $ 886 $ 719 --------- --------- --------- --------- --------- ---------
The weighted average annual assumed rate of increase in the per capita cost of covered benefits (I.E., health care cost trend rate) for the medical plans is 8% for fiscal 1998, and is assumed to decrease gradually to 5% by the year 2001, and remain at that level thereafter. A one-percentage point increase in F-21 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (9) EMPLOYEE BENEFITS (CONTINUED) each year would increase the accumulated postretirement benefit obligation and the net periodic postretirement benefit cost by $612 and $48, respectively. The weighted average discount rate used in determining the accumulated postretirement benefit obligation was 7.75% and 7.50% at October 31, 1996 and 1997, respectively. DEFINED CONTRIBUTION AND PROFIT SHARING PLANS The Company sponsors a 401(k) plan that covers substantially all salaried and hourly employees. Participants can contribute up to 15% of compensation on a before-tax basis. The Company matches 25% of the first 6% of a participant's before-tax contribution. The Company's expense representing its matching contribution was $307, $360 and $499 for the years ended October 31, 1995, 1996 and 1997, respectively. Plan assets consist primarily of investments in common stock and debt securities. On February 28, 1995, the Company adopted a profit sharing program, which covers substantially all salaried and hourly employees. The program provides for a distribution to employees equal to 15% of income before income tax expense. At management's discretion, a portion of the distribution may be made in the form of a contribution to the 401(k) plan. The remainder is paid in cash to employees. The Company's expense for the years ended October 31, 1995, 1996 and 1997 was $1,388, $3,492 and $493, respectively. FOREIGN PLANS In Peru, severance indemnities are determined according to governmental regulations and provided for on an accrual basis for the amount that would be paid if all personnel were to retire at each balance sheet date. These amounts are deposited semi-annually into the workers' individual bank accounts. In accordance with government regulations in Peru, employees are entitled to receive 8% of the Doe Run Peru's taxable income, 50% of which is distributed to employees based on number of days worked, and the remaining distributed in proportion to their salaries. (10) PREFERRED STOCK (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS) The Company had 2,500 shares of preferred stock with a $1,000 par value authorized, issued and outstanding at October 31, 1996 and 1997. The shares are owned by Renco. The shares are redeemable solely at the option of the Company at $1,000 per share plus any unpaid dividends. Cumulative annual dividends of $80 per share are payable quarterly on the first day of January, April, July and October and must be paid before dividends on common stock can be paid. The Company declared and paid dividends of $100 per share on each of its 2,500 shares on December 30, 1996. Dividends in arrears at October 31, 1996 and 1997 were $168 and $118, respectively. At October 31, 1996 and 1997, no dividends were accrued as none had been declared. F-22 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (11) BUSINESS AND CREDIT CONCENTRATIONS Lead prices fluctuate and are affected by numerous factors beyond the Company's control, including expectations for inflation, speculative activities, the relative exchange rate of the U.S. dollar, global and regional demand and production, political and economic conditions and production costs in major producing regions. The aggregate effect of these factors makes it impossible for the Company to predict lead prices. Fluctuations in the lead price could have a material adverse effect on the results of operations, financial condition, and liquidity of the Company. For the years ended October 31, 1995, 1996 and 1997 approximately 59%, 67% and 63%, respectively, of the Company's revenues were from U.S. battery manufacturers (primarily automotive) or their suppliers. At October 31, 1996 and 1997, the accounts receivable balances related to these U.S. battery manufacturers were $39,246 and $35,162, respectively. For the years ended October 31, 1995, 1996 and 1997 the Company relied on one battery customer, Johnson Controls, Inc., for approximately 13%, 14% and 12% of its revenue, respectively. Related accounts receivable balances were $9,394 and $6,501 at October 31, 1996 and 1997, respectively. An additional 10% of revenues were attributed to East Penn Manufacturing Co., Inc., a battery manufacturer, for the year ended October 31, 1996, and Big River Zinc Corporation for the year ended October 31, 1997. No other customer accounted for greater than 10% of revenues for the year ended October 31, 1995. (12) SEGMENT INFORMATION The Company operates in one industry segment for financial reporting purposes. Doe Run Peru's net sales and income from operations were $2,571 and $359, respectively, for the period from October 23 to October 31, 1997. There were no intraenterprise sales between geographic segments during this period. Doe Run Peru's identifiable assets were $171,000 at October 31, 1997. (13) COMMITMENTS AND CONTINGENCIES INVESTMENT COMMITMENT According to the Contract described in Note 2, Doe Run Peru is obligated to invest $120,000 through October 23, 2002 to expand and modernize its operations, including certain expenditures to comply with environmental regulations in Peru, as discussed in Note 14. In the event Doe Run Peru has not fulfilled its obligations under the Contract, it will be obligated to pay in 2002 a penalty to Centromin Peru S.A. equal to 30% of any shortfall. Management plans to fund its commitments through future operating cash flows. TOLLING The Company has entered into a tolling arrangement with a major battery manufacturer whereby the manufacturer will deliver spent lead-acid batteries and other lead-bearing material to the Company's recycling facility and, for a processing fee, the Company will return finished lead metal. The agreement, which expires in September 1999, covers approximately 14% of the Company's anticipated domestic lead metal production. F-23 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (13) COMMITMENTS AND CONTINGENCIES (CONTINUED) SALES The Company has commitments to sell approximately 70% of its anticipated domestic lead production under agreements, with terms of generally less than one year. Sales prices are generally based on the London Metal Exchange prices at the time of shipment, plus a premium. HEDGING The fair market value of the Company's hedging positions at October 31, 1996 and 1997, is the difference between quoted prices at the respective period-end and the contract settlement value. The fair market value represents the estimated net cash the Company would receive (pay) if the contracts were canceled on the respective dates. As management has designated these contracts as hedges, the related gains and losses will be recognized in net sales when the related production is sold.

The Company is exposed to risk from market price fluctuations to the extent it cannot meet anticipated sales. The Company does not obtain collateral or other security to support hedge instruments subject to credit risk, but assesses the reliability and reputation of its counterparties before contracts are established. F-24 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (13) COMMITMENTS AND CONTINGENCIES (CONTINUED) LETTERS OF CREDIT At October 31, 1996 and 1997, the Company's lender had issued irrevocable standby letters of credit totaling $5,342 and $6,100, respectively, in connection with the Company's insurance and bonding activities. At October 31, 1997, the Company's lender had issued a $3,300 standby letter of credit as a guarantee for a potential purchase price adjustment related to the acquisition of Metaloroya, as required by the Contract. EMPLOYMENT AGREEMENTS The Company has employment agreements with a number of its senior executives through October 31, 1999. ADDITIONAL PAYMENTS RELATED TO ACQUISITIONS The terms of an agreement with the previous owners of The Doe Run Company (predecessor to the Company) provided that, beginning with the fiscal period ending October 31, 1994, additional payments may be required based on a percentage of gross margin for those periods in excess of a specified base amount. Payments made under the agreement were $237 and $5,778 in the fiscal years ended October 31, 1996 and 1997, respectively. In conjunction with the retirement of the obligations due to the previous owners, the amount paid exceeded recorded obligations by $5,108. This amount was recorded as additional purchase price paid for the assets of the Company acquired from the previous owners. The Company was released from further obligation under the agreement. Pursuant to an Asset Purchase Agreement (the "Purchase Agreement") additional consideration may be due to the former owners of Seafab if certain earnings levels are met for the five-year period beginning November 1, 1996. Payments made in fiscal 1997 totaled $181. (14) ENVIRONMENTAL AND LITIGATION MATTERS ENVIRONMENTAL DOMESTIC OPERATIONS Doe Run is subject to numerous federal, state and local environmental laws and regulations governing, among other things, air emissions, waste water discharge, solid and hazardous waste treatment, and storage, disposal and remediation of releases of hazardous materials. In common with much of the mining industry, Doe Run's facilities are located on sites that have been used for heavy industrial purposes for decades and may require remediation. Doe Run has made and intends to continue making the necessary expenditures for environmental remediation and compliance with environmental laws and regulations. Environmental laws and regulations may become more stringent in the future which could increase costs of compliance. The Company has recorded a liability of $35,527 as of October 31, 1997, which represents management's best estimate of known obligations relating to environmental and reclamation matters, which are discussed below. Primary smelter slag produced by and stored at the primary smelter in Herculaneum, Missouri is currently exempt from hazardous waste regulation under the Resource Conservation and Recovery Act of 1976, as amended ("RCRA"). The Company has accrued approximately $1,200 related to the Herculaneum F-25 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (14) ENVIRONMENTAL AND LITIGATION MATTERS (CONTINUED) smelter's operations, primarily for closure obligations. However, the EPA recently published a proposed rule, which, if adopted, would require this slag to be managed as a hazardous waste. Certain other waste materials, including baghouse dust, generated at the smelter and now recycled in the smelter may also become regulated as hazardous wastes. At this time, the Company cannot predict the final outcome of the EPA's proposed rule. However, the EPA has indicated, notwithstanding the full RCRA requirements, the rule will not be imposed, in particular, that the slag will not be regulated. If the slag or other wastes at the smelter were to be regulated as hazardous waste, the Company may be required to take corrective action under RCRA at the smelter, as well as to adopt stricter management practices for these wastes. The Company is working with regulators at the Herculaneum smelter to develop a new three-year compliance plan to meet the ambient air quality standard for lead promulgated under the federal Clean Air Act. The plan will take effect after fiscal 1998 to implement control measures identified in the plan. The Company expects to make capital expenditures for additional control measures totaling approximately $2,800 for fiscal 1998 while the plan is developed and anticipates future cash requirements of $3,000 for the three-year plan. Doe Run has received notice that it is a potentially responsible party ("PRP") subject to liability under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended ("CERCLA"), at four sites in St. Francois County, Missouri: the Big River Mine Tailings Site, the Bonne Terre Site, the Federal site, and the National site; the Oronogo-Durenweg site in Jasper County, Missouri; the Cherokee County site in Cherokee County, Kansas; the Tar Creek site in Ottawa County, Oklahoma; the Block "P" site in Cascade County, Montana; and the Missouri Electric Works site in Cape Girardeau, Missouri. In addition, there are four sites in St. Francois County for which the EPA has indicated it will issue notice. These sites involve historical operations of predecessors of the Company. CERCLA provides for strict and, in certain circumstances, joint and several liability for response costs and natural resource damages. Doe Run signed a voluntary Administrative Order of Consent ("AOC") in 1994 with the EPA to remediate the Big River Mine Tailings Site. In February 1997, Doe Run signed an AOC to perform an Engineering Evaluation/Cost Analysis on the Bonne Terre Site. In addition to remediating the mine waste areas at these sites, the Company has signed an AOC with the EPA to conduct a Remedial Investigation/ Feasibility Study ("RIFS") to assess potential off-site impacts of site operations on and the need for remediation regarding groundwater, residential soils, several creeks and a river. The RIFS is being conducted by a third party and is approximately one-third complete, with completion expected within one year. The Block "P" site in Montana was a polymetallic mine with a waste facility located on U.S. Forest Service land. Studies of the tailings site, mine and the potential impacts on surface water have been requested by the State of Montana. The Company has a reserve as of October 31, 1997 of approximately $17,800 for these sites, including the four additional sites in St. Francois County. Doe Run's recycling facility is subject to corrective action requirements under RCRA, as a result of a storage permit for certain wastes issued in 1989. This has required and may involve future remediation of solid waste management units at the site. Although it is not possible to predict whether completed actions will be approved or new actions required, the Company has reserves as of October 31, 1997 of approximately $1,900 for future corrective actions and $2,600 for closure costs for the permitted storage area. The Company's domestic operating facilities have wastewater discharge permits issued under the federal Clean Water Act, as amended. It is expected that stricter discharge limits than previously in effect will be included in permits now subject to renewal. As a result, there will be additional treatment facilities F-26 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (14) ENVIRONMENTAL AND LITIGATION MATTERS (CONTINUED) required, with anticipated total capital expenditures of $4,000 over the next five years to meet applicable permit requirements. There will be no appreciable increase in operating costs. The Company's mining and milling operations include five mine waste disposal facilities that are subject to Missouri mine closure permit requirements. The total expected cost of closure is $11,000. The Company has begun certain closure requirements ahead of closure and is also accruing for the cost of ultimate closure at a rate of approximately $300 per year. The Company's mine closure reserves were approximately $4,800 as of October 31, 1997. FOREIGN OPERATIONS Doe Run Peru has negotiated a capital spending plan with the Peruvian government to invest $107,575 during the next nine years to meet its obligations under the Programa de Adecuacion y Manejo Ambiental (Environmental Adjustment and Management Program) (the "PAMA") as follows:
ESTIMATED YEAR COSTS - ---------------------------------------------------------------------------------- ---------- 1998.............................................................................. $ 2,700 1999.............................................................................. 3,612 2000.............................................................................. 4,963 2001.............................................................................. 3,300 2002.............................................................................. 3,000 2003.............................................................................. 3,800 2004.............................................................................. 2,775 2005.............................................................................. 38,700 2006.............................................................................. 44,725 ---------- $ 107,575 ---------- ----------
According to the Contract, the Company has the option to continue the use of Doe Run Peru's existing zinc ferrite disposal site for three years, after which it can take ownership of the site or create a new site. If the Company chooses to take ownership of the site, it will be responsible for its closure costs. The Company has accrued for management's estimate of the closure costs, or $7,200. If the Company abandons the ferrite site, it must pay this amount to Centromin Peru S.A. CONSOLIDATED The Company believes its reserves for domestic and foreign environmental and reclamation matters are adequate, based on the information available. Depending upon the type and extent of remediation activities required, costs in excess of established reserves are reasonably possible. Therefore, there can be no assurance that additional costs, both individually and in the aggregate, would not have a material adverse effect on the results of operations, financial condition and liquidity of the Company. LITIGATION The Company is a defendant in several lawsuits alleging certain damages stemming from the operations at the Herculaneum smelter. Two of these cases are class action lawsuits. In one case, the plaintiffs seek to have certified two separate classes. The first class would consist of property owners in a certain section of Herculaneum, alleging that property values have been damaged due to the operations of the smelter. The second class alleged is comprised of children who lived in Herculaneum during a period F-27 THE DOE RUN RESOURCES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (DOLLARS IN THOUSANDS) (14) ENVIRONMENTAL AND LITIGATION MATTERS (CONTINUED) of time when they were six months to six years old, and the remedy sought is medical monitoring for the class. The second class action similarly is seeking certification of a class of property owners allegedly damaged by operations from the smelter, but the purported size of the class is every home in Herculaneum, Missouri. The other two cases are personal injury actions by fourteen individuals who allege damages from the effects of lead poisoning due to operations at the smelter. Punitive damages also are being sought in each case. The Company is vigorously defending all of these claims. Preliminary investigation and research by the Company indicates property values in Herculaneum are consistent with those of surrounding communities and have not been affected by the smelter. Finally, based on rules for class certification, the Company believes class certification is not appropriate. However, because the cases are in the early stages of discovery, the Company is unable at this time to state with certainty the expected outcome of and the final costs of any of these cases. Therefore, there can be no assurance that these cases would not have a material adverse effect, both individually and in the aggregate, on the results of operations, financial condition and liquidity of the Company. (15) SUBSEQUENT EVENTS On March 12, 1998, the Company completed the sale of $200,000 11.25% Senior Notes due 2005 (the "Fixed Rate Notes") and $55,000 Floating Interest Rate Senior Notes due 2003 (collectively, the "Notes"). The Notes are guaranteed by certain subsidiaries of the Company (see Note 16). The Company used $125,000 of the proceeds from the Notes to make a deposit (the "Special Term Deposit") in a bank, which in turn loaned such amount (the "Back-to-Back Loan") to Doe Run Mining. The Special Term Deposit and the Back-to-Back Loan have payment terms that match the timing and amount of the payments on $125,000 of the Fixed Rate Notes, except that additional interest of 0.50% for the first six months and 0.25% thereafter through September 11, 2004 is payable on the Back-to-Back Loan. The Back-to-Back Loan is collateralized by the Special Term Deposit. Doe Run Mining used the proceeds of the Back-to-Back Loan to repay the $100,000 balance on the $225,000 term loan, plus accrued interest thereon of $1,004, repay the $23,000 subordinated note to the Company and pay fees of $313. The remaining $130,000 of the proceeds of the Notes, plus the $23,000 repayment of the subordinated note by Doe Run Mining, were used by the Company to: (i) repay principal and interest on the $130,000 term loan of $128,125 and $1,127, respectively, (ii) repay the revolving loan balance of $14,444, (iii) pay Renco $5,000 to redeem the $2,500 preferred stock, plus accrued dividends thereon of $188, and a transaction fee of $2,312 and (iv) pay related fees and expenses of $6,553. As a result of these transactions, the Company expects to recognize an extraordinary loss of approximately $5,800, net of income taxes.

F-34 REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Board of Directors Empresa Minera del Centro del Peru S.A.--Centromin Peru S.A.: We have audited the accompanying statements of assets and liabilities of La Oroya Metallurgical Complex (La Oroya), a division of the Peruvian state-owned corporation Empresa Minera del Centro del Peru S.A.--Centromin Peru S.A. (Centromin), as of December 31, 1995 and 1996 and October 23, 1997 and the related statements of revenues and expenses, changes in net assets and cash flows for each of the years in the three-year period ended December 31, 1996 and the period from January 1 to October 23, 1997. These financial statements are the responsibility of Centromin's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. As explained in Note 2, the above financial statements which have been prepared from Centromin's accounting records, remeasured into U.S. dollars and prepared following generally accepted accounting principles in the United States of America, are intended to reflect separately the assets, liabilities, revenues and expenses of La Oroya, as if La Oroya had operated as a separate entity and applying certain allocations by Centromin on the basis described in Note 4 and therefore, they may not necessarily reflect the financial position and results of operations of La Oroya as if it were effectively a separate legal entity for the periods indicated above. In our opinion, the financial statements referred to above, present fairly, for the purpose described in the preceding paragraph, the assets and liabilities of La Oroya as of December 31, 1995 and 1996 and October 23, 1997, and its revenues and expenses and cash flows for each of the years in the three-year period ended December 31, 1996 and the period from January 1 to October 23, 1997, in conformity with accounting principles generally accepted in the United States of America.

The accompanying notes are an integral part of these financial statements. F-39 EMPRESA MINERA DEL CENTRO DEL PERU S.A.--CENTROMIN PERU S.A. LA OROYA DIVISION NOTES TO THE FINANCIAL STATEMENTS AS OF OCTOBER 23, 1997 AND DECEMBER 31, 1996, 1995 AND 1994 (1) BUSINESS AND DISPOSITION The metallurgical complex of La Oroya (hereinafter "La Oroya") a division of Empresa Minera del Centro del Peru S.A.--Centromin Peru S.A. (hereinafter "Centromin") is engaged in the smelting and refining of polymetalic concentrates and marketing and sale of refined metals. La Oroya primarily smelts and refines the concentrates of polymetalic ores from the mining units of Centromin, which include copper, lead and zinc. The operations of La Orya are conducted through the Centromin organization systems, which include administrative, legal, operating tasks, and all other necessary functions that support its operations. Centromin is engaged in mining activities as specified by the General Mining Law (Supreme Decree 014-92-EM), as well as in industrial activities necessary to sustain mining operations. On October 23, 1997, Centromin Peru S.A. contributed certain assets and liabilities of La Oroya to a newly formed company, Metaloroya S.A. ("Metaloroya"), in exchange for shares in Metaloroya. Concurrent with the transfer, Centromin sold all of the shares received to Doe Run Peru S.R. Ltda. ("Doe Run Peru"), a wholly owned subsidiary of Doe Run Mining S.R. Ltda., an indirect wholly owned subsidiary of The Doe Run Resources Corporation. (2) BASIS OF PRESENTATION The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The financial statements of La Oroya division have been prepared in accordance with the accounting principles generally accepted in the United States of America ("U.S. GAAP"), which differ in certain significant respects from generally accepted accounting principles in Peru. In addition, these financial statements were prepared based on Centromin's accounting records related to the metallurgical complex of La Oroya as if La Oroya had operated as a separate entity and applying certain allocation methodologies, as specified in Note 4. Unless otherwise indicated, all amounts in the financial statements and in these notes are presented in thousands of U.S. dollars (US$). (3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES INVENTORY Inventory is stated at the lower of cost or net realized value. The cost of refined metals and concentrates for sale, as well as metal and concentrates for sale, as well as metal and concentrates in process is determined under the first-in, first-out method ("FIFO"). The cost of materials, supplies and spare parts is determined using the average cost method. F-40 EMPRESA MINERA DEL CENTRO DEL PERU S.A.--CENTROMIN PERU S.A. LA OROYA DIVISION NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) AS OF OCTOBER 23, 1997 AND DECEMBER 31, 1996, 1995 AND 1994 (3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at cost. Depreciation is calculated on a straight-line basis at the rates indicated in Note 8. Maintenance and minor repairs are charged to expenses as incurred. Material improvements and renewals are capitalized. In accordance with the Statement of Financial Accounting Standard No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of" ("SFAS 121"), La Oroya's management has determined that there is no impairment of its long-lived assets. SEVERANCE INDEMNITIES Severance indemnities are determined according to governmental regulations and are provided for on an accrual basis for the amount, which would be paid if all personnel were to retire at the date of each statement of assets and liabilities. Under Legislative Decree 650, an accrued liability was established to recognize the liability for personnel severance indemnities earned by employees prior to December 31, 1990. These severance indemnities, which are adjusted for subsequent wage increases, are required to be funded over a maximum term of ten years, beginning in June 1991. The funding of this obligation eliminates any adjustment for subsequent wages increases. In 1996, La Oroya fully funded this obligation. Liabilities relating to personnel severance indemnities earned by employees after 1991 are accrued and semi-annually deposited into workers' individual bank accounts. REVENUE RECOGNITION Sales are recorded when title passes to the customer, which occurs at the time of shipment. With respect to concentrates, sales are recorded based on estimated weights, assays and prices. All such concentrate sales are adjusted when final weights, assays and prices are known. Adjustments to the provisional billings are made in the period during which additional information becomes available. INTEREST CAPITALIZATION Interest expense allocable to the construction of the oxygen plant of US $4,297 was capitalized until the start-up of its operations in 1994. Capitalized interest is expensed over the depreciable life of the asset to which it relates. INCOME TAX AND WORKERS' PROFIT SHARING La Oroya is included in Centromin's income tax return. According, La Oroya has provided income tax and remitted to Centromin any tax payable, calculated as if it were filing separate tax returns. Under Statement of Financial Accounting Standard No. 109, "Accounting for Income taxes" ("SFAS 109"), which designates the liability method as the required accounting method for taxes under U.S. GAAP, La Oroya recognizes the tax effect of certain temporary differences between the financial reporting basis of assets and liabilities and the related tax basis. F-41 EMPRESA MINERA DEL CENTRO DEL PERU S.A.--CENTROMIN PERU S.A. LA OROYA DIVISION NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) AS OF OCTOBER 23, 1997 AND DECEMBER 31, 1996, 1995 AND 1994 (3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Likewise, La Oroya recognizes the effect of temporary differences between book and tax basis of assets and liabilities related to workers' profit sharing on a basis similar to that used for income taxes. (4) ALLOCATION METHODOLOGIES As described in Note 2, La Oroya's transactions are recorded in Centromin's accounting systems. The operations of La Oroya conducted through Centromin have been presented using assumptions and allocations which management believes are reasonable. They include the following: (a) Centromin's assets and liabilities not specifically identifiable to La Oroya have not been allocated in the accompanying financial statements. These are cash and bank accounts, credit on value-added tax and liabilities to certain suppliers of administrative services. (b) Sales have been allocated based on the preliminary and final billings of the exported refined metals and concentrates identified with La Oroya. (c) Costs of production have been allocated based on the following: - Concentrates acquired from Centromin's mining units were transferred at market value as if La Oroya were an independent party. - The depreciation charge was based on the fixed assets specifically identifiable to La Oroya. - Other allocated costs, included power, were based on the ratio of La Oroya's usage to total usage by Centromin (mainly time incurred and consumption of goods and services). (d) Expenses relating to corporate accounting, finance and administrative services provided by Centromin have been allocated based on the ratio of La Oroya's usage to total usage by Centromin. (e) Selling and marketing expenses have been allocated based on usage estimated by management. (f) Interest and bank charges are those which are directly related to La Oroya's bank loans and overdrafts obtained during the year. (g) Workers' profit sharing and income tax were provided based on the actual results as if La Oroya had been operating as a separate entity. (5) REMEASUREMENT INTO U.S. DOLLAR La Oroya maintains its accounting records in Peruvian Nuevos Soles. Those financial statements have been remeasured into U.S. dollars, which is its functional currency, for all periods presented, in accordance with SFAS 52 using the following methodology: (a) Non-monetary accounts have been remeasured at historical exchange rates. F-42 EMPRESA MINERA DEL CENTRO DEL PERU S.A.--CENTROMIN PERU S.A. LA OROYA DIVISION NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) AS OF OCTOBER 23, 1997 AND DECEMBER 31, 1996, 1995 AND 1994 (5) REMEASUREMENT INTO U.S. DOLLAR (CONTINUED) (b) Monetary accounts in Peruvian currency have been remeasured at the following free market exchange rates for buying (assets) and selling (liabilities) in effect at the end of the respective period, which are in Peruvian Nuevos soles per U.S. dollar:
AS OF DECEMBER 31, AS OF ------------------------------- OCTOBER 23, 1994 1995 1996 1997 --------- --------- --------- ------------- Assets................................................... 2.16 2.299 2.596 2.667 Liabilities.............................................. 2.19 2.322 2.603 2.669
(c) Income and expenses, other than depreciation, that have been remeasured at the historical exchange rates that applied to the related assets, have been remeasured at average monthly basis at average exchange rates. Cost of sales was determined from its components once remeasured. The net effect of foreign exchange difference for each period is reflected in the accompanying statement of revenues and expenses. (6) FOREIGN CURRENCY TRANSACTIONS AND EXCHANGE RISK EXPOSURE Under current law, foreign currency transactions are made through the financial banking system at free market exchange rates. The assets and liabilities denominated in Peruvian Nuevos Soles are as follows (in thousands):
AS OF DECEMBER 31, AS OF -------------------- OCTOBER 23, 1995 1996 1997 --------- --------- ----------- Assets-- Cash and deposits in banks................................ -- 184 169 Accounts receivable....................................... 4,055 1,602 3,698 --------- --------- ----------- 4,055 1,786 3,867 --------- --------- ----------- Liabilities-- Trade accounts payable.................................... 7,549 6,919 6 Remuneration and taxes payable............................ 12,249 12,257 15,298 Accrued liabilities....................................... 5,721 9,504 2,200 --------- --------- ----------- 25,519 28,680 17,504 --------- --------- ----------- Net position............................................

The net effects of exchange differences were US$3,840, US$2,050 and US$1,884 for the 1994, 1995 and 1996 years, respectively and US$269 for the period from January 1 to October 23, 1997. F-43 EMPRESA MINERA DEL CENTRO DEL PERU S.A.--CENTROMIN PERU S.A. LA OROYA DIVISION NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) AS OF OCTOBER 23, 1997 AND DECEMBER 31, 1996, 1995 AND 1994 (7) MATERIALS, SUPPLIES AND SPARE PARTS This account is comprised of the following:
AS OF DECEMBER 31, AS OF -------------------- OCTOBER 23, 1995 1996 1997 --------- --------- ----------- Materials, supplies and spare parts......................... $ 25,714 $ 8,335 $ 11,748 Supplies in transit......................................... 2,935 490 -- --------- --------- ----------- 28,649 8,825 11,748 --------- --------- ----------- Less--allowance for obsolescence............................ (161) (522) (522) $ 28,488 $ 8,303 $ 11,226 --------- --------- ----------- --------- --------- -----------
In management's opinion, the balance of the allowance for obsolescence adequately covers the related risk as of each statement of assets and liabilities date. (8) PROPERTY, PLANT AND EQUIPMENT AND ACCUMULATED DEPRECIATION This account is comprised of the following:
AS OF DECEMBER 31, AS OF ANNUAL RATE OF ----------------------- OCTOBER 23, DESCRIPTION DEPRECIATION 1995 1996 1997 - --------------------------------------------------------- ---------------- ---------- ----------- ----------- Land..................................................... -- $ 97 $ 97 $ 97 Buildings and other premises............................. 3% to 10% 21,335 21,335 21,335 Machinery and equipment.................................. 6.67% to 30% 112,072 112,072 112,072 Furniture and fixtures................................... 10% to 15% 1,388 1,388 1,388 Other equipment.......................................... 10% to 20% 13,153 13,153 13,153 Construction in progress................................. -- 3,005 3,005 3,005 ---------- ----------- ----------- 151,050 151,050 151,050 Accumulated depreciation.................................

Fully depreciated assets amounted to US$80,684, US$80,857, and US$80,907 as of December 31, 1995, 1996 and October 23, 1997. There were no significant additions to property, plant and equipment during the period presented above. The accounting records of Centromin do not identify the minor additions to fixed assets (other than construction in progress) by specific year and, therefore, it is not possible to determine fixed asset additions specifically related to La Oroya in each year. Accordingly, in the preparation of the accompanying financial statements, the fixed assets in service at October 23, 1997 have been assumed to be in service as of each balance sheet date and for each period presented. F-44 EMPRESA MINERA DEL CENTRO DEL PERU S.A.--CENTROMIN PERU S.A. LA OROYA DIVISION NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) AS OF OCTOBER 23, 1997 AND DECEMBER 31, 1996, 1995 AND 1994 (9) BANK LOANS Bank loans are short-term obligations, which were obtained from local and foreign financial institutions for working capital purposes. As of December 31, 1995 and 1996 and as of October 23, 1997, 70 percent, 100 percent and 100 percent, respectively, of bank loans were denominated in U.S. dollars. The fair value of these loans approximate their carrying value. The loans bear interest at international market rates. The weighted average interest rate on bank loans at December 31, 1995 and 1996 and October 23, 1997 was 8.1 percent, 6.5 percent and 6.7 percent, respectively.

(13) SEVERANCE INDEMNITIES According to current government regulations, the liability for personnel severance indemnities earned by employees prior to December 31, 1990, as adjusted for subsequent wage increases until such time as the liability is funded, must be accrued and funded over a maximum term of 10 years, beginning in June 1991. The funding of this obligation eliminates any retroactive adjustments from subsequent wage increases. In 1996, La Oroya fully funded this obligation. Obligations relating to personnel severance indemnities accrued subsequent to 1990 are paid semi-annually through deposits in workers' individual bank accounts. The analysis of the account is as follows:
AS OF DECEMBER 31, AS OF -------------------- OCTOBER 23, 1995 1996 1997 --------- --------- ----------- Balance at the beginning of period......................... $ 22,540 $ 21,228 $ 2,186 Provision................................................ $ 6,040 $ 5,926 2,154 Payments and advances....................................

(1,602) (1,603) (195) --------- --------- ----------- Balance at the end of period............................... $ 21,228 $ 2,186 $ 1,185
In addition, as of December 31, 1995 and 1996, certain employees had elected to deposit their indemnity payments amounting to US$3,579 and US$1973 respectively, with Centromin. In 1997, all such indemnity liabilities were transferred to banks as directed by each employee. (14) TAXATION AND WORKERS' PROFIT SHARING Centromin is subject to the Peruvian tax regulations, which require that income tax be determined based on financial statements adjusted to reflect the changes in the wholesale price level, following the methodology prescribed by Legislative Decree 797. The statutory income tax rate in Peru is 30% of the taxable income. In 1992, the Peruvian law established an alternative minimum tax of 2 percent, which is calculated based on the total assets. Beginning in 1994, exporting corporations may deduct from the F-46 EMPRESA MINERA DEL CENTRO DEL PERU S.A.--CENTROMIN PERU S.A. LA OROYA DIVISION NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) AS OF OCTOBER 23, 1997 AND DECEMBER 31, 1996, 1995 AND 1994 (14) TAXATION AND WORKERS' PROFIT SHARING (CONTINUED) minimum income tax base the accounts receivable and inventories related to export activities and the value of fixed assets acquired during the current year, for two consecutive years. In May 1997, the minimum income tax was abrogated and an extraordinary tax was imposed equal to 0.5% of the net assets declared in the 1996 income tax return. This tax constitutes a credit against the monthly income tax prepayments made from July through December 1997 and the regularization payment for the 1997 year. La Oroya is included in Centromin's tax return. As such it has provided income tax, and remitted any tax due to Centromin, based upon the statutory tax rate in effect for each period, applied as if La Oroya filed a separate income tax return. In May 1994, Centromin signed a Tax Stabilization Agreement with the Peruvian government for a ten-year period beginning in 1997. The following conditions would be guaranteed to Centromin: - Utilization of the tax rules prevailing on April 25, 1994. - Custom duties will be calculated at rates ranging from 15% to 25%. - Free commercialization of its products. - No restriction in the use of proceeds from export sales. - Free conversion of foreign currency generated by local sales. - No discrimination in foreign currency transactions. In accordance with current workers' profit sharing government regulations, La Oroya's workers have the right to receive 8 percent of La Oroya's taxable income, of which 50 percent is distributed among all employees based on the number of days worked by each employee and the remaining amount is distributed in proportion to their salaries. Such profit sharing is limited to 18 times the annual salary for each worker. Any excess is to be reserved and expended for training of workers. The provision for income tax and workers' profit sharing is comprised of the following for each of the years in the period ended December 31, 1996 and for the period from January 1 to October 23, 1997:

The privatization costs include costs related to moving La Oroya's personnel away from the metallurgical complex of Centromin. These costs consist mainly of demolition and construction of apartments, colleges and parks at the new location. (16) PERSONNEL REDUCTION COSTS La Oroya recognized a charge in 1995 of US$2,504 related to the first part of its personnel reduction program. This amount was fully paid in 1995. In January 1996, the Board of Directors approved a second personnel reduction program which applied to an additional 600 workers. The estimated cost of US$3,894 was recorded in expenses in 1996. An additional provision of US$1,490 was recorded in the period from January 1 to October 23, 1997, in connection with the second personnel reduction program. (17) COMMITMENTS AND CONTINGENCIES ENVIRONMENTAL MATTERS In 1995, in compliance with Supreme Decree 016-93-EM, amended by Supreme Decree 059-93-EM, (Regulation for the Environmental Protection in the Mining and Metallurgical Activities), Centromin filed a preliminary evaluation of its mining units and of the smelter and refineries in La Oroya, which were approved by the Ministry of Energy and Mining (the competent authority).

LA OROYA DIVISION NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) AS OF OCTOBER 23, 1997 AND DECEMBER 31, 1996, 1995 AND 1994 (17) COMMITMENTS AND CONTINGENCIES (CONTINUED) At the date of that report, in compliance with the provisions of such decrees and according to the preliminary evaluation above mentioned, Centromin prepared a Programa de Adecuacion y Manejo Ambiental (Environmental Adjustment and Management Program) (the "PAMA") for La Oroya metallurgical complex. The program comprises the development of engineering projects to remediate any existing environmental problems and to comply with current environmental regulations. This program, which was approved by the competent authority in January 1997, establishes total future disbursements of US$21.5 million to remediate the damages to the environment and to establish methods of compliance with current environmental regulations. The Company recognized a charge to operations in 1996 for the estimated cost of such remedial actions (see Note 15). The remediation program and the investment in environmental control equipment required to comply with current regulations is to be implemented over a ten year period beginning in 1997. Management expects that the cost of future investments, principally for pollution control equipment, will be capitalized in future periods and depreciated over the periods to be benefited. In accordance with a revised program approved by the Ministry of Energy and Mining, the disbursements are estimated by management to be as follows:

In addition, PAMA estimated the cost to eventually close the metallurgical complex of La Oroya at US$24 million. No provision has been recorded for this amount, since there are no plans to close the complex. The timing and amounts listed in the above table are estimates and actual amounts and timing of payments could vary from the estimates. Furthermore, in accordance with the Article 9 of the rules of the General Law on Mining, annual expenditures for environmental remediation and control cannot be less than 1 percent of total sales. F-50 EMPRESA MINERA DEL CENTRO DEL PERU S.A.--CENTROMIN PERU S.A. LA OROYA DIVISION NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) AS OF OCTOBER 23, 1997 AND DECEMBER 31, 1996, 1995 AND 1994 (17) COMMITMENTS AND CONTINGENCIES (CONTINUED) POTENTIAL TAX ASSESSMENTS Centromin's income tax returns of 1993 through 1996, as well as the net worth tax returns of 1992 and 1993, are pending review by the National Superintendency of Tax Administration. No significant liabilities arose as a result of the 1992 income tax return review. If tax assessments were made, any tax, interest or surcharges would be charged to expense in the years in which the assessment is known. In the opinion of Centromin's management there are no matters that should result in significant additional tax assessments. INVESTMENT PROGRAM As discussed in Note 14, in May 1994 Centromin signed a Tax Stabilization Agreement with the Peruvian Government for a ten-year period beginning the year in which Centromin meets the Investment Program for La Oroya metallurgical complex, which was then estimated at US$11.1 million. The investment program was completed in December, 1996. In March 1997, the Mining Bureau approved the completion of the Investment Program. Actual expenditures amounted to approximately US$11.5 million. CONTINGENCIES At October 23, 1997, La Oroya metallurgical complex has legal suits aggregating US$15.7 million related to labor matters. The financial statements include a reserve of US$1.7 million (see note 12) estimated to cover the cost of defending and settling such matters. In management and legal advisors' opinion, the ultimate outcome of these suits will not result in a material adverse effect on La Oroya's financial position and results of operations. In addition, there is a contingency amounting to approximately US$12 million, related to demands filed by 19 local mining companies, which are claiming the refund of value-added-tax withheld by La Oroya from 1975 to 1980. In opinion of La Oroya's management and its legal advisors, the ultimate outcome of these demands will be favorable to La Oroya. SALES COMMITMENTS AND CONCENTRATION La Oroya derives its revenue from the sale of its refined metals and concentrates to several customers. La Oroya's three largest customers accounted for: 11%, 6% and 6%, respectively, of net sales in the period from January 1 to October 23, 1997. The percentages in 1994 were 13%, 11% and 10%; in 1995 were 15%, 14% and 12% and in 1996 were 11%, 7% and 6%. These customers have sales contracts, which guarantee their supply at prices derived from international market quotations. (18) RELATED PARTY TRANSACTIONS Expenses allocated from Centromin to the operations of La Oroya related primarily to accounting and administrative support services. These expenses amounted to US$5,223 in the period from January 1 to October 23, 1997, US$5,660 in 1996, US$4,479 in 1995 and US$4,569 in 1994.

F-52 GLOSSARY OF CERTAIN METALLURGY TERMS "Anode copper" means copper blister that, in a furnace, has been blown with air and natural gas to upgrade its purity to approximately 99.0% copper, which is then cast into keystone shaped slabs that are shipped to an electrolytic refinery. "Bullion" means unrefined raw metals containing impurities. "By-products" means the products recovered during the refining process, such as silver, germanium and indium, which may produce gains for the smelter. "Cathode" means the electrolytically refined form of copper removed from the refining cells in the refining process that are sold "as is" or melted and cast into cakes, billets, wirebar or rods. "Concentrates" means ores that have been crushed, ground and treated in a flotation process that separates and concentrates the minerals creating the raw material for smelting. "Converter" means a principal phase of the smelting process that involves the blowing of oxygen-enriched air through molten metal, causing oxidation and the removal of sulfur and other impurities. "Copper blister" means the material resulting from passing copper concentrates through a converter that is approximately 98.5% copper and takes its name from "blisters" that form on the surface. "Electrolytic refining" means the process of placing copper anodes alternately with refined copper sheets in a tank through which a copper sulfate solution and sulfuric acid are circulated and a low voltage current is introduced that causes the copper metal to transfer from the anodes to the pure copper sheets, producing 99.9% copper cathodes. "Electrowinning" means the process of removing metal from solution by the action of electric currents. "Flotation" means the process by which minerals attach themselves to the bubbles in an oily froth and rise to the top where they are skimmed off. "Flux" means inert oxides of iron, calcium, silica added to the charge to be smelted or pyrometallurgically converted to assist with the creation of a molten slag to assist separation of the metal from the low melting molten oxides. "Galvanizing" means the anti-corrosion process for steel components that consists of dipping components in a molten zinc bath after chemically stripping off impurities. "Leaching" means the process of extracting a metal from ores via hydrometallurgical techniques by dissolving the metal into a solution for subsequent treatment or recovery. "Lead/zinc bullion" means unrefined raw metals containing impurities. "Ore" means a mineral or aggregate of minerals from which metal can be economically mined or extracted.

INDEMNIFICATION OF DIRECTORS AND OFFICERS Sections 722 and 723 of the Business Corporation Law of New York (the "NYBCL") empower The Doe Run Resources Corporation, a New York corporation ("Doe Run"), to indemnify, subject to the limitations and standards set forth therein, any person made or threatened to be made a party to an action or proceeding brought or threatened by reason of the fact that such person is or was a director or officer of Doe Run, Section 726 of the NYBCL provides that Doe Run may purchase insurance on behalf of any such director or officer. Article V of Doe Run's By-Laws provides, in effect, for the indemnification by Doe Run of each director, officer, employee or agent of Doe Run to the full extent permitted by the NYBCL. The By-Laws of Doe Run provide, in effect, that Doe Run shall indemnify any person made, or threatened to be made, a party to an action or proceeding, whether civil or criminal, including an action by or in the right of Doe Run to procure a judgment in its favor and an action by or in the right of any other corporation of any type or kind, domestic or foreign, or any partnership, joint venture, trust, employee benefit plan or any other enterprise which any director or officer of Doe Run served in any capacity at the request of Doe Run, by reason of the fact that he, his testator or intestate is or was a director or officer of Doe Run, or served such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise in any capacity, against judgments, fines, amounts paid in settlement and reasonable expenses, including attorneys' fees, actually and necessarily incurred as a result of such action or proceeding or any appeal therein. Subsection (a) of Section 145 of the General Corporation Law of Delaware (the "DGCL") empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or complete action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he is or was a director, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no cause to believe his conduct was unlawful. Subsection (b) of Section 145 of the DGCL empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification may be made in respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine that despite the adjudication of liability such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper. Section 145 of the DGCL further provides that to the extent a director, officer, employee or agent of a corporation has been successful in the defense of any action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein, he shall be indemnified against expenses II-1 (including attorneys' fees) actually and reasonably incurred by him in connection therewith; that indemnification or advancement of expenses provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and empowers the corporation to purchase and maintain insurance on behalf of a director, officer, employee or agent of the corporation against any liability asserted against him or incurred by him in any such capacity or arising out of his status as such whether or not the corporation would have the power to indemnify him against such liabilities under Section 145. The Certificate of Incorporation of Fabricated Products, Inc., a Delaware corporation ("FPI"), provides that a director of FPI shall not be personally liable to FPI or its stockholders for monetary damages for breach of fiduciary duty as a director except for liability (i) for any breach of the director's duty of loyalty to FPI or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derives an improper personal benefit. The Bylaws of FPI provide, in effect, that FPI shall indemnify every person who was or is a party, or is or was threatened to be made a party, to any action, suit, or proceeding, whether civil, criminal, administrative, or investigative, by reason of the fact that he or she is or was a director, officer, employee, or agent of FPI, or is or was serving at the request of FPI as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, against expenses (including attorneys' fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit, or proceedings, to the fullest extent permitted by applicable law. Such indemnifications may, in the discretion of the board of directors, include advances of the person's expenses in advance of final disposition of such action, suit, or proceeding, subject to the provisions of any applicable statute. FPI is empowered to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of FPI, or is or was serving at the request of FPI as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against any liability incurred by such person in such capacity, or arising out of such person's capacity. The Companies Law (1995 Revision) of the Cayman Islands does not set out any specific restrictions on the ability of a company to indemnify officers or directors. However, the application of basic principles and certain Commonwealth case law, which is likely to be persuasive in the Cayman Islands, would indicate that indemnification is generally permissible except in the event that there had been fraud or willful default on the part of the officer or director or reckless disregard of his duties and obligations to the company. Article 123 of the Articles of Association of Doe Run Cayman Ltd., a Cayman Islands company ("Doe Run Cayman"), provides, in effect, that Doe Run Cayman shall indemnify the directors and officers of Doe Run Cayman and any trustees acting in relation to any of the affairs of Doe Run Cayman and their heirs, executors, administrators and personal representatives respectively from and against all actions, proceedings, costs, charges, losses, damages and expenses which they or any of them shall or may incur or sustain by reason of any act done or omitted in or about the execution of their duty in their respective offices or trusts, except such (if any) as they shall incur or sustain by or through their own wilful neglect or default respectively. Peruvian law does not provide for the indemnification of officers of companies organized as Sociedades de Responsibilidad Limitada, which do not have directors. The Constituciones de Sociedad Comercial de Responsibilidad Limitada for Doe Run Mining S.R. Ltda. and Doe Run Peru S.R. Ltda. do not contain any provisions regarding the indemnification of officers.

ITEM 22. UNDERTAKINGS Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling any Registrant pursuant to the foregoing provisions, each Registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by a Registrant of expenses incurred or paid by a director, officer or controlling person of a Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling II-4 person in connection with the securities being registered, each Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. The undersigned Registrants hereby undertake: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned Registrants hereby undertake that: (1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of a registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of the registration statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. The undersigned Registrants hereby undertake to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means.

Voting. The holders of Preferred Stock shall not have rights as to any matter whatever. DIVISION B - COMMON STOCK 1. Designation. The 1,000 shares of Common Stock shall be designated "Common Stock". 2. Dividends.

Distribution of Assets. In the event of any liquidation, dissolution or winding up of the Corporation, or any reduction of its capital, resulting in a distribution of its assets to stockholders, whether voluntary or involuntary, then, after there shall have been paid or set apart for the holders of the Preferred Stock the full preferential amounts to which they are entitled, the holders of the Common Stock shall be entitled to receive as a class, pro rata, all of the remaining assets of the Corporation available for distribution to its stockholders. 4. Voting Power. The holders of the Common Stock shall possess exclusive voting power for the election of directors and for all other purposes and each holder thereof shall be entitled to one vote for each share thereof. DIVISION C - GENERAL PROVISIONS No holder of any of the shares of the stock or options, warrants or other rights to purchase stock or 4 of other securities of the Corporation, shall be entitled as of right to purchase or subscribe for any unissued stock of any class or any additional shares of any class to be issued by reason of any increase in authorized capital stock of the Corporation of any class, or certificates of indebtedness, debentures or other securities convertible into or exchangeable for stock of the Corporation of any class, or carrying any right to purchase stock of any class, but any such unissued stock, additional authorized issue of any stock or securities convertible into or exchangeable for stock or carrying any right to purchase stock, may be issued and disposed of pursuant to resolution of the Board of Directors to such persons, firms, corporations or associations, whether such holders or others, and upon such terms, as may be deemed advisable by the Board of Directors in the exercise of its sole discretion." 5.

The indemnification authorized under the foregoing sentence shall in no case include (a) amounts paid in settling or otherwise disposing of a threatened action or a pending action with or without court approval, or (b) expenses incurred in defending a threatened action or a pending action which is settled or otherwise disposed of without court approval.

At least 10 days and not more than 60 days before any meeting of stockholders, written notice stating the time and place of the meeting, and also its purpose in the case of a special meeting, shall be delivered personally to, or mailed with postage prepaid to the last known address of, each stockholder of record entitled to vote at the meeting. If a meeting is adjourned to another time or place, notice of the adjourned meeting must be given to all the stockholders entitled to vote at the adjourned meeting if (i) the adjournment is for more than 30 days, (ii) a new record date is fixed for the adjourned meeting, or (iii) the time and place of the adjourned meeting are not announced at the meeting at which the adjournment is taken. The stockholders may transact any business at the adjourned meeting which could have been transacted at the original meeting. 4. Waiver of Notice. A stockholder may waive notice of any or all meetings by delivering to the corporation a written waiver signed by such person. The stockholder may deliver the waiver before, after, or at the time when it is stated to be effective. The attendance of a stockholder at any meeting shall be deemed a waiver of notice of the meeting by such person, unless the attendance is only for the purpose of objecting that the meeting was unlawfu1ly convened and the person so objects at the start of the meeting. 5. Quorum. A majority of the shares entitled to vote, either present in person or represented by proxy, shall constitute a quorum for the transaction of any business at a meeting of stockholders. 6. Voting. Each share of stock shall entitle the holder of record to one vote.

A plurality of the same shall be sufficient for the election of directors. 7. Representation by Proxy. Any stockholder may authorize another person or persons to act for it by proxy in all matters in which the stockholder is entitled to participate. The proxy shall be in writing, dated, and signed by the stockholder or its authorized agent. The proxy shall be valid, unless sooner revoked, until the expiration of the period stated in the proxy, or until 3 years after the date of the proxy if no period is stated. A proxy shall be irrevocable if it so states, but only if and so long as it is coupled with an interest in the stock itself or the corporation in general. 8. Action by Consent. Any action required or permitted to be taken at a meeting of stockholders may be taken without a meeting and without prior notice if a sufficient number of stockholders deliver to the corporation, within a 60-day period, properly executed written consents to the action. A consent shall be properly executed if it is signed by the stockholder, bears the date of signature, and sets forth the action taken. The number of stockholders which is sufficient for this purpose shall be any number which represents at least the minimum number of votes that would be required were the action to be taken at a meeting at which all the shares entitled to vote on the matter were present and voted. Any action taken as described in this paragraph has the same effect as an action taken at a duly called and convened meeting of Stockholders. 9. Record Date. The record date for determining the stockholders entitled to notice of or to vote at any meeting of stockholders shall be determined in accordance with Article V, paragraph 5. 10. List of Stockholders. At least 10 days before any meeting of stockholders, the secretary shall make a list of all stockholders entitled to vote at the meeting, arranged in 2 alphabetical order and showing each stockholder's address and the number of shares registered in such person's name.

ARTICLE VI Indemnification 1. General. The corporation shall indemnify every person who was or is a party, or is or was threatened to be made a party, to any action, suit, or proceeding, whether civil, criminal, administrative, or investigative, by reason of the fact that he or she is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, against expenses (including attorneys' fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit, or proceeding, to the fullest extent permitted by applicable law. Such indemnification may, in the discretion of the board of directors, include advances of the person's expenses in advance of final disposition of such action, suit, or proceeding, subject to the provisions of any applicable statute. 2. Rights Not Exclusive. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article VI shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any law, bylaw, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in the indemnified party's official capacity and as to action in another capacity while holding such office. 3.

Definition of "corporation." For the purposes of this Article VI, references to "the corporation" include any constituent corporation absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its director, officers, employees, and agents as well as the resulting or surviving corporation. As a result, any person who is or was a director, officer, employee, or agent of such a constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise shall stand in the same position under the provisions of this Article VI with respect to the resulting or surviving corporation as he or she would if he or she had served the resulting or surviving corporation in the same capacity. 5.

The provisions of these Articles relating to general meetings shall apply to every such general meeting of the holders of one class of shares except that the necessary quorum shall be one person holding or representing by proxy at least one-third of the issued shares of -5- the class and that any holder of shares of the class present in person or by proxy may demand a poll. 13. The rights conferred upon the holders of the shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu therewith. COMMISSION ON SALE OF SHARES 14. The Company may in so far as the Statute from time to time permits pay a commission to any person in consideration of his subscribing or agreeing to subscribe whether absolutely or conditionally for any shares of the Company. Such commissions may be satisfied by the payment of cash or the lodgement of fully or partly paid-up shares or partly in one way and partly in the other. The Company may also on any issue of shares pay such brokerage as may be lawful. NON-RECOGNITION OF TRUSTS 15. No person shall be recognised by the Company as holding any share upon any trust and the Company shall not be bound by or be compelled in any way to recognise (even when having notice thereof) any equitable, contingent, future, or partial interest in any share, or any interest in any fractional part of a share, or (except only as is otherwise provided by these Articles or the Statute) any other rights in respect of any share except an absolute right to the entirety thereof in the registered holder. LIEN ON SHARES 16. The Company shall have a first and paramount lien and charge on all shares (whether fully paid-up or not) registered in the name of a Member (whether solely or jointly with others) for all debts, liabilities or engagements to or with the Company (whether presently payable or not) by such Member or his estate, either alone or jointly with any other person, whether a Member or not, but the Directors may at any time declare any share to be wholly or in part exempt from the provisions of this Article. The registration of a transfer of any such share shall operate as a waiver of the Company's lien (if any) thereon. The Company's lien (if any) on a share shall extend to all dividends or other monies payable in respect thereof. 17. The Company may sell, in such manner as the Directors think fit, any shares on which the Company has a lien, but no sale shall be made unless a sum in respect of which the lien exists is presently payable, nor until the expiration of fourteen days after a notice in -6- writing stating and demanding payment of such part of the amount in respect of which the lien exists as is presently payable, has been given to the registered holder or holders for the time being of the share, or the person, of which the Company has notice, entitled thereto by reason of his death or bankruptcy. 18. To give effect to any such sale the Directors may authorise some person to transfer the shares sold to the purchaser thereof. The purchaser shall be registered as the holder of the shares comprised in any such transfer, and he shall not be bound to see to the application of the purchase money, nor shall his title to the shares be affected by any irregularity or invalidity in the proceedings in reference to the sale. 19. The proceeds of such sale shall be received by the Company and applied in payment of such part of the amount in respect of which the lien exists as is presently payable and the residue, if any, shall (subject to a like lien for sums not presently payable as existed upon the shares before the sale) be paid to the person entitled to the shares at the date of the sale. CALL ON SHARES 20. (a) The Directors may from time to time make calls upon the Members in respect of any monies unpaid on their shares (whether on account of the nominal value of the shares or by way of premium or otherwise) and not by the conditions of allotment thereof made payable at fixed terms, provided that no call shall be payable at less than one month from the date fixed for the payment of the last preceding call, and each Member shall (subject to receiving at least fourteen days notice specifying the time or times of payment) pay to the Company at the time or times so specified the amount called on the shares. A call may be revoked or postponed as the Directors may determine. A call may be made payable by instalments. (b) A call shall be deemed to have been made at the time when the resolution of the Directors authorising such call was passed. (c) The joint holders of a share shall be jointly and severally liable to pay all calls in respect thereof. 21. If a sum called in respect of a share is not paid before or on a day appointed for payment thereof, the persons from whom the sum is due shall pay interest on the sum from the day appointed for payment thereof to the time of actual payment at such rate not exceeding ten per cent per annum as the Directors may determine, but the Directors shall be at liberty to waive payment of such interest either wholly or in part. 22. Any sum which by the terms of issue of a share becomes payable on allotment or at any fixed date, whether on account of the nominal value of the share or by way of -7- premium or otherwise, shall for the purposes of these Articles be deemed to be a call duly made, notified and payable on the date on which by the terms of issue the same becomes payable, and in the case of non-payment all the relevant provisions of these Articles as to payment of interest forfeiture or otherwise shall apply as if such sum had become payable by virtue of a call duly made and notified. 23. The Directors may, on the issue of shares, differentiate between the holders as to the amount of calls or interest to be paid and the times of payment. 24. (a) The Directors may, if they think fit, receive from any Member willing to advance the same, all or any part of the monies uncalled and unpaid upon any shares held by him, and upon all or any of the monies so advanced may (until the same would but for such advances, become payable) pay interest at such rate not exceeding (unless the Company in general meeting shall otherwise direct) seven per cent per annum, as may be agreed upon between the Directors and the Member paying such sum in advance. (b) No such sum paid in advance of calls shall entitle the Member paying such sum to any portion of a dividend declared in respect of any period prior to the date upon which such sum would, but for such payment, become presently payable. FORFEITURE OF SHARES 25. (a) If a Member fails to pay any call or instalment of a call or to make any payment required by the terms of issue on the day appointed for payment thereof, the Directors may, at any time thereafter during such time as any part of the call, instalment or payment remains unpaid, give notice requiring payment of so much of the call, instalment or payment as is unpaid, together with any interest which may have accrued and all expenses that have been incurred by the Company by reason of such non-payment. Such notice shall name a day (not earlier than the expiration of fourteen days from the date of giving of the notice) on or before which the payment required by the notice is to be made, and shall state that, in the event of non-payment at or before the time appointed the shares in respect of which such notice was given will be liable to be forfeited. (b) If the requirements of any such notice as aforesaid are not complied with, any share in respect of which the notice has been given may at any time thereafter, before the payment required by the notice has been made, be forfeited by a resolution of the Directors to that effect. Such forfeiture shall include all dividends declared in respect of the forfeited share and not actually paid before the forfeiture. (c) A forfeited share may be sold or otherwise disposed of on such terms and in such manner as the Directors think fit and at any time before a sale or disposition the forfeiture may be cancelled on such terms as the Directors think fit. -8- 26. A person whose shares have been forfeited shall cease to be a Member in respect of the forfeited shares, but shall, notwithstanding, remain liable to pay to the Company all monies which, at the date of forfeiture were payable by him to the Company in respect of the shares together with interest thereon, but his liability shall cease if and when the Company shall have received payment in full of all monies whenever payable in respect of the shares. 27. A certificate in writing under the hand of one Director or the Secretary of the Company that a share in the Company has been duly forfeited on a date stated in the declaration shall be conclusive evidence of the fact therein stated as against all persons claiming to be entitled to the share. The Company may receive the consideration given for the share on any sale or disposition thereof and may execute a transfer of the share in favour of the person to whom the share is sold or disposed of and he shall thereupon be registered as the holder of the share and shall not be bound to see to the application of the purchase money, if any, nor shall his title to the share be affected by any irregularity or invalidity in the proceedings in reference to the forfeiture, sale or disposal of the share. 28. The provisions of these Articles as to forfeiture shall apply in the case of non-payment of any sum which, by the terms of issue of a share, becomes payable at a fixed time, whether on account of the nominal value of the share or by way of premium as if the same had been payable by virtue of a call duly made and notified. REGISTRATION OF EMPOWERING INSTRUMENTS 29. The Company shall be entitled to charge a fee not exceeding one dollar (US$1.00) on the registration of every probate, letters of administration, certificate of death or marriage, power of attorney, notice in lieu of distringas, or other instrument. TRANSMISSION OF SHARES 30. In case of the death of a Member, the survivor or survivors where the deceased was a joint holder, and the legal personal representatives of the deceased where he was a sole holder, shall be the only persons recognised by the Company as having any title to his interest in the shares, but nothing herein contained shall release the estate of any such deceased holder from any liability in respect of any shares which had been held by him solely or jointly with other persons. 31. (a) Any person becoming entitled to a share in consequence of the death or bankruptcy or liquidation or dissolution of a Member (or in any other way than by transfer) may, upon such evidence being produced as may from time to time be required by the -9- Directors and subject as hereinafter provided, elect either to be registered himself as holder of the share or to make such transfer of the share to such other person nominated by him as the deceased or bankrupt person could have made and to have such person registered as the transferee thereof, but the Directors shall, in either case, have the same right to decline or suspend registration as they would have had in the case of a transfer of the share by that Member before his death or bankruptcy as the case may be. (b) If the person so becoming entitled shall elect to be registered himself as holder he shall deliver or send to the Company a notice in writing signed by him stating that he so elects. 32. A person becoming entitled to a share by reason of the death or bankruptcy or liquidation or dissolution of the holder (or in any other case than by transfer) shall be entitled to the same dividends and other advantages to which he would be entitled if he were the registered holder of the share, except that he shall not, before being registered as a Member in respect of the share, be entitled in respect of it to exercise any right conferred by membership in relation to meetings of the Company PROVIDED HOWEVER that the Directors may at any time give notice requiring any such person to elect either to be registered himself or to transfer the share and if the notice is not complied with within ninety days the Directors may thereafter withhold payment of all dividends, bonuses or other monies payable in respect of the share until the requirements of the notice have been complied with. AMENDMENT OF MEMORANDUM OF ASSOCIATION, CHANGE OF LOCATION OF REGISTERED OFFICE & ALTERATION OF CAPITAL 33. (a) Subject to and in so far as permitted by the provisions of the Statute, the Company may from time to time by ordinary resolution alter or amend its Memorandum of Association otherwise than with respect to its name and objects and may, without restricting the generality of the foregoing: (i) increase the share capital by such sum to be divided into shares of such amount or without nominal or par value as the resolution shall prescribe and with such rights, priorities and privileges annexed thereto, as the Company in general meeting may determine. (ii) consolidate and divide all or any of its share capital into shares of larger amount than its existing shares; (iii) by subdivision of its existing shares or any of them divide the whole or any part of its share capital into shares of smaller amount than is fixed by the Memorandum of Association or into shares without nominal or par value; -10- (iv) cancel any shares which at the date of the passing of the resolution have not been taken or agreed to be taken by any person. (b) All new shares created hereunder shall be subject to the same provisions with reference to the payment of calls, liens, transfer, transmission, forfeiture and otherwise as the shares in the original share capital. (c) Subject to the provisions of the Statute, the Company may by Special Resolution change its name or alter its objects. (d) Without prejudice to Article 11 hereof and subject to the provisions of the Statute, the Company may by Special Resolution reduce its share capital and any capital redemption reserve fund. (e) Subject to the provisions of the Statute, the Company may by resolution of the Directors change the location of its registered office. CLOSING REGISTER OF MEMBERS OR FIXING RECORD DATE 34. For the purpose of determining Members entitled to notice of or to vote at any meeting of Members or any adjournment thereof, or Members entitled to receive payment of any dividend, or in order to make a determination of Members for any other proper purpose, the Directors of the Company may provide that the register of Members shall be closed for transfers for a stated period but not to exceed in any case forty days. If the register of Members shall be so closed for the purpose of determining Members entitled to notice of or to vote at a meeting of Members such register shall be so closed for at least ten days immediately preceding such meeting and the record date for such determination shall be the date of the closure of the register of Members. 35. In lieu of or apart from closing the register of Members, the Directors may fix in advance a date as the record date for any such determination of Members entitled to notice of or to vote at a meeting of the Members and for the purpose of determining the Members entitled to receive payment of any dividend the Directors may, at or within 90 days prior to the date of declaration of such dividend fix a subsequent date as the record date for such determination. 36. If the register of Members is not so closed and no record date is fixed for the determination of Members entitled to notice of or to vote at a meeting of Members or Members entitled to receive payment of a dividend, the date on which notice of the meeting is mailed or the date on which the resolution of the Directors declaring such dividend is adopted, as the case may be, shall be the record date for such determination of Members. -11- When a determination of Members entitled to vote at any meeting of Members has been made as provided in this section, such determination shall apply to any adjournment thereof. GENERAL MEETING 37. (a) Subject to paragraph (c) hereof, the Company shall within one year of its incorporation and in each year of its existence thereafter hold a general meeting as its annual general meeting and shall specify the meeting as such in the notices calling it. The annual general meeting shall be held at such time and place as the Directors shall appoint and if no other time and place is prescribed by them, it shall be held at the registered office on the second Wednesday in December of each year at ten o'clock in the morning. (b) At these meetings the report of the Directors (if any) shall be presented. (c) If the Company is exempted as defined in the Statute it may but shall not be obliged to hold an annual general meeting. 38. (a) The Directors may whenever they think fit, and they shall on the requisition of Members of the Company holding at the date of the deposit of the requisition not less than one-tenth of such of the paid-up capital of the Company as at the date of the deposit carries the right of voting at general meetings of the Company, proceed to convene a general meeting of the Company. (b) The requisition must state the objects of the meeting and must be signed by the requisitionists and deposited at the registered office of the Company and may consist of several documents in like form each signed by one or more requisitionists. (c) If the Directors do not within twenty-one days from the date of the deposit of the requisition duly proceed to convene a general meeting, the requisitionists, or any of them representing more than one-half of the total voting rights of all of them, may themselves convene a general meeting, but any meeting so convened shall not be held after the expiration of three months after the expiration of the said twenty-one days. (d) A general meeting convened as aforesaid by requisitionists shall be convened in the same manner as nearly as possible as that in which general meetings are to be convened by Directors. -12- NOTICE OF GENERAL MEETINGS 39. At least five days' notice shall be given of an annual general meeting or any other general meeting. Every notice shall be exclusive of the day on which it is given or deemed to be given and of the day for which it is given and shall specify the place, the day and the hour of the meeting and the general nature of the business and shall be given in manner hereinafter mentioned or in such other manner if any as may be prescribed by the Company PROVIDED that a general meeting of the Company shall, whether or not the notice specified in this regulation has been given and whether or not the provisions of Article 38 have been complied with, be deemed to have been duly convened if it is so agreed: (a) in the case of a general meeting called as an annual general meeting by all the Members entitled to attend and vote thereat or their proxies; and (b) in the case of any other general meeting by a majority in number of the Members having a right to attend and vote at the meeting, being a majority together holding not less than seventy-five per cent in nominal value or in the case of shares without nominal or par value seventy-five per cent of the shares in issue, or their proxies. 40. The accidental omission to give notice of a general meeting to, or the non-receipt of notice of a meeting by any person entitled to receive notice shall not invalidate the proceedings of that meeting. PROCEEDINGS AT GENERAL MEETINGS 41. No business shall be transacted at any general meeting unless a quorum of Members is present at the time when the meeting proceeds to business; two Members present in person or by proxy shall be a quorum provided always that if the Company has one Member of record the quorum shall be that one Member present in person or by proxy. 42. A resolution (including a Special Resolution) in writing (in one or more counterparts) signed by all Members for the time being entitled to receive notice of and to attend and vote at general meetings (or being corporations by their duly authorised representatives) shall be as valid and effective as if the same had been passed at a general meeting of the Company duly convened and held. 43. If within half an hour from the time appointed for the meeting a quorum is not present, the meeting, if convened upon the requisition of Members, shall be dissolved and in any other case it shall stand adjourned to the same day in the next week at the same time and -13- place or to such other time or such other place as the Directors may determine and if at the adjourned meeting a quorum is not present within half an hour from the time appointed for the meeting the Members present shall be a quorum. 44. The Chairman, if any, of the Board of Directors shall preside as Chairman at every general meeting of the Company, or if there is no such Chairman, or if he shall not be present within fifteen minutes after the time appointed for the holding of the meeting, or is unwilling to act, the Directors present shall elect one of their number to be Chairman of the meeting. 45. If at any general meeting no Director is willing to act as Chairman or if no Director is present within fifteen minutes after the time appointed for holding the meeting, the Members present shall choose one of their number to be Chairman of the meeting. 46. The Chairman may, with the consent of any general meeting duly constituted hereunder, and shall if so directed by the meeting, adjourn the meeting from time to time and from place to place, but no business shall be transacted at any adjourned meeting other than the business left unfinished at the meeting from which the adjournment took place. When a general meeting is adjourned for thirty days or more, notice of the adjourned meeting shall be given as in the case of an original meeting; save as aforesaid it shall not be necessary to give any notice of an adjournment or of the business to be transacted at an adjourned general meeting. 47. At any general meeting a resolution put to the vote of the meeting shall be decided on a show of hands unless a poll is, before or on the declaration of the result of the show of hands, demanded by the Chairman or any other Member present in person or by proxy. 48. Unless a poll be so demanded a declaration by the Chairman that a resolution has on a show of hands been carried, or carried unanimously, or by a particular majority, or lost, and an entry to that effect in the Company's Minute Book containing the Minutes of the proceedings of the meeting shall be conclusive evidence of that fact without proof of the number or proportion of the votes recorded in favour of or against such resolution. 49. The demand for a poll may be withdrawn. 50. Except as provided in Article 52, if a poll is duly demanded it shall be taken in such manner as the Chairman directs and the result of the poll shall be deemed to be the resolution of the general meeting at which the poll was demanded. 51. In the case of an equality of votes, whether on a show of hands or on a poll, the Chairman of the general meeting at which the show of hands takes place or at which the poll is demanded, shall be entitled to a second or casting vote. -14- 52. A poll demanded on the election of a Chairman or on a question of adjournment shall be taken forthwith. A poll demanded on any other question shall be taken at such time as the Chairman of the general meeting directs and any business other than that upon which a poll has been demanded or is contingent thereon may be proceeded with pending the taking of the poll. VOTES OF MEMBERS 53. Subject to any rights or restrictions for the time being attached to any class or classes of shares, on a show of hands every Member of record present in person or by proxy at a general meeting shall have one vote and on a poll every Member of record present in person or by proxy shall have one vote for each share registered in his name in the register of Members. 54. In the case of joint holders of record the vote of the senior who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of the other joint holders, and for this purpose seniority shall be determined by the order in which the names stand in the register of Members. 55. A Member of unsound mind, or in respect of whom an order has been made by any court, having jurisdiction in lunacy, may vote, whether on a show of hands or on a poll, by his committee, receiver, curator bonis, or other person in the nature of a committee, receiver or curator bonis appointed by that court, and any such committee, receiver, curator bonis or other persons may vote by proxy. 56. No Member shall be entitled to vote at any general meeting unless he is registered as a shareholder of the Company on the record date for such meeting nor unless all calls or other sums presently payable by him in respect of shares in the Company have been paid. 57. No objection shall be raised to the qualification of any voter except at the general meeting or adjourned general meeting at which the vote objected to is given or tendered and every vote not disallowed at such general meeting shall be valid for all purposes. Any such objection made in due time shall be referred to the Chairman of the general meeting whose decision shall be final and conclusive. 58. On a poll or on a show of hands votes may be given either personally or by proxy. -15- PROXIES 59. The instrument appointing a proxy shall be in writing and shall be executed under the hand of the appointor or of his attorney duly authorised in writing, or, if the appointor is a corporation under the hand of an officer or attorney duly authorised in that behalf. A proxy need not be a Member of the Company. 60. The instrument appointing a proxy shall be deposited at the registered office of the Company or at such other place as is specified for that purpose in the notice convening the meeting no later than the time for holding the meeting, or adjourned meeting provided that the Chairman of the Meeting may at his discretion direct that an instrument of proxy shall be deemed to have been duly deposited upon receipt of telex, cable or telecopy confirmation from the appointor that the instrument of proxy duly signed is in the course of transmission to the Company. 61. The instrument appointing a proxy may be in any usual or common form and may be expressed to be for a particular meeting or any adjournment thereof or generally until revoked. An instrument appointing a proxy shall be deemed to include the power to demand or join or concur in demanding a poll. 62. A vote given in accordance with the terms of an instrument of proxy shall be valid notwithstanding the previous death or insanity of the principal or revocation of the proxy or of the authority under which the proxy was executed, or the transfer of the share in respect of which the proxy is given provided that no intimation in writing of such death, insanity, revocation or transfer as aforesaid shall have been received by the Company at the registered office before the commencement of the general meeting, or adjourned meeting at which it is sought to use the proxy. 63. Any corporation which is a Member of record of the Company may in accordance with its Articles or in the absence of such provision by resolution of its Directors or other governing body authorise such person as it thinks fit to act as its representative at any meeting of the Company or of any class of Members of the Company, and the person so authorised shall be entitled to exercise the same powers on behalf of the corporation which he represents as the corporation could exercise if it were an individual Member of record of the Company. 64. Shares of its own capital belonging to the Company or held by it in a fiduciary capacity shall not be voted, directly or indirectly, at any meeting and shall not be counted in determining the total number of outstanding shares at any given time. -16- DIRECTORS 65. There shall be a Board of Directors consisting of not less than one or more than ten persons (exclusive of alternate Directors) PROVIDED HOWEVER that the Company may from time to time by ordinary resolution increase or reduce the limits in the number of Directors. The first Directors of the Company shall be determined in writing by, or appointed by a resolution of, the subscribers of the Memorandum of Association or a majority of them. 66. The remuneration to be paid to the Directors shall be such remuneration as the Directors shall determine. Such remuneration shall be deemed to accrue from day to day. The Directors shall also be entitled to be paid their travelling, hotel and other expenses properly incurred by them in going to, attending and returning from meetings of the Directors, or any committee of the Directors, or general meetings of the Company, or otherwise in connection with the business of the Company, or to receive a fixed allowance in respect thereof as may be determined by the Directors from time to time, or a combination partly of one such method and partly the other. 67. The Directors may by resolution award special remuneration to any Director of the Company undertaking any special work or services for, or undertaking any special mission on behalf of, the Company other than his ordinary routine work as a Director. Any fees paid to a Director who is also counsel or solicitor to the Company, or otherwise serves it in a professional capacity shall be in addition to his remuneration as a Director. 68. A Director or alternate Director may hold any other office or place of profit under the Company (other than the office of Auditor) in conjunction with his office of Director for such period and on such terms as to remuneration and otherwise as the Directors may determine. 69. A Director or alternate Director may act by himself or his firm in a professional capacity for the Company and he or his firm shall be entitled to remuneration for professional services as if he were not a Director or alternate Director. 70. A shareholding qualification for Directors may be fixed by the Company in general meeting, but unless and until so fixed no qualification shall be required. 71. A Director or alternate Director of the Company may be or become a director or other officer of or otherwise interested in any company promoted by the Company or in which the Company may be interested as shareholder or otherwise and no such Director or alternate Director shall be accountable to the Company for any remuneration or other benefits received by him as a director or officer of, or from his interest in, such other company. -17- 72. No person shall be disqualified from the office of Director or alternate Director or prevented by such office from contracting with the Company, either as vendor, purchaser or otherwise, nor shall any such contract or any contract or transaction entered into by or on behalf of the Company in which any Director or alternate Director shall be in any way interested be or be liable to be avoided, nor shall any Director or alternate Director so contracting or being so interested be liable to account to the Company for any profit realised by any such contract or transaction by reason of such Director holding office or of the fiduciary relation thereby established. A Director (or his alternate Director in his absence) shall be at liberty to vote in respect of any contract or transaction in which he is so interested as aforesaid PROVIDED HOWEVER that the nature of the interest of any Director or alternate Director in any such contract or transaction shall be disclosed by him or the alternate Director appointed by him at or prior to its consideration and any vote thereon. 73. A general notice that a Director or alternate Director is a shareholder of any specified firm or company and is to be regarded as interested in any transaction with such firm or company shall be sufficient disclosure under Article 72 and after such general notice it shall not be necessary to give special notice relating to any particular transaction. ALTERNATE DIRECTORS 74. Subject to the exception contained in Article 82, a Director who expects to be unable to attend Directors' Meetings because of absence, illness or otherwise may appoint any person to be an alternate Director to act in his stead and such appointee whilst he holds office as an alternate Director shall, in the event of absence therefrom of his appointor, be entitled to attend meetings of the Directors and to vote thereat and to do, in the place and stead of his appointor, any other act or thing which his appointor is permitted or required to do by virtue of his being a Director as if the alternate Director were the appointor, other than appointment of an alternate to himself, and he shall ipso facto vacate office if and when his appointor ceases to be a Director or removes the appointee from office. Any appointment or removal under this Article shall be effected by notice in writing under the hand of the Director making the same. -18- POWERS AND DUTIES OF DIRECTORS 75. The business of the Company shall be managed by the Directors (or a sole Director if only one is appointed) who may pay all expenses incurred in promoting, registering and setting up the Company, and may exercise all such powers of the Company as are not, from time to time by the Statute, or by these Articles, or such regulations, being not inconsistent with the aforesaid, as may be prescribed by the Company in general meeting required to be exercised by the Company in general meeting PROVIDED HOWEVER that no regulations made by the Company in general meeting shall invalidate any prior act of the Directors which would have been valid if that regulation had not been made. 76. The Directors may from time to time and at any time by powers of attorney appoint any company, firm, person or body of persons, whether nominated directly or indirectly by the Directors, to be the attorney or attorneys of the Company for such purpose and with such powers, authorities and discretions (not exceeding those vested in or exercisable by the Directors under these Articles) and for such period and subject to such conditions as they may think fit, and any such powers of attorney may contain such provisions for the protection and convenience of persons dealing with any such attorneys as the Directors may think fit and may also authorise any such attorney to delegate all or any of the powers, authorities and discretions vested in him. 77. All cheques, promissory notes, drafts, bills of exchange and other negotiable instruments and all receipts for monies paid to the Company shall be signed, drawn, accepted, endorsed or otherwise executed as the case may be in such manner as the Directors shall from time to time by resolution determine. 78.

(d) Any such delegates as aforesaid may be authorised by the Directors to subdelegate all or any of the powers, authorities, and discretions for the time being vested in them. MANAGING DIRECTORS 82. The Directors may, from time to time, appoint one or more of their body (but not an alternate Director) to the office of Managing Director for such term and at such remuneration (whether by way of salary, or commission, or participation in profits, or partly in one way and partly in another) as they may think fit but his appointment shall be subject to determination ipso facto if he ceases from any cause to be a Director and no alternate Director appointed by him can act in his stead as a Director or Managing Director. -20- 83. The Directors may entrust to and confer upon a Managing Director any of the powers exercisable by them upon such terms and conditions and with such restrictions as they may think fit and either collaterally with or to the exclusion of their own powers and may from time to time revoke, withdraw, alter or vary all or any of such powers. PROCEEDINGS OF DIRECTORS 84. Except as otherwise provided by these Articles, the Directors shall meet together for the despatch of business, convening, adjourning and otherwise regulating their meetings as they think fit. Questions arising at any meeting shall be decided by a majority of votes of the Directors and alternate Directors present at a meeting at which there is a quorum, the vote of an alternate Director not being counted if his appointor be present at such meeting. In case of an equality of votes, the Chairman shall have a second or casting vote. 85. A Director or alternate Director may, and the Secretary on the requisition of a Director or alternate Director shall, at any time summon a meeting of the Directors by at least two days' notice in writing to every Director and alternate Director which notice shall set forth the general nature of the business to be considered unless notice is waived by all the Directors (or their alternates) either at, before or after the meeting is held and PROVIDED FURTHER if notice is given in person, by cable, telex or telecopy the same shall be deemed to have been given on the day it is delivered to the Directors or transmitting organisation as the case may be. The provisions of Article 40 shall apply mutatis mutandis with respect to notices of meetings of Directors. 86. The quorum necessary for the transaction of the business of the Directors may be fixed by the Directors and unless so fixed shall be two, a Director and his appointed alternate Director being considered only one person for this purpose, PROVIDED ALWAYS that if there shall at any time be only a sole Director the quorum shall be one. For the purposes of this Article an alternate Director or proxy appointed by a Director shall be counted in a quorum at a meeting at which the Director appointing him is not present. 87. The continuing Directors may act notwithstanding any vacancy in their body, but if and so long as their number is reduced below the number fixed by or pursuant to these Articles as the necessary quorum of Directors the continuing Directors or Director may act for the purpose of increasing the number of Directors to that number, or of summoning a general meeting of the Company, but for no other purpose. 88. The Directors may elect a Chairman of their Board and determine the period for which he is to hold office; but if no such Chairman is elected, or if at any meeting the Chairman is not present within five minutes after the time appointed for holding the same, the Directors present may choose one of their number to be Chairman of the meeting. -21- 89. The Directors may delegate any of their powers to committees consisting of such member or members of the Board of Directors (including Alternate Directors in the absence of their appointors) as they think fit; any committee so formed shall in the exercise of the powers so delegated conform to any regulations that may be imposed on it by the Directors. 90. A committee may meet and adjourn as it thinks proper. Questions arising at any meeting shall be determined by a majority of votes of the members present, and in the case of an equality of votes the Chairman shall have a second or casting vote. 91. All acts done by any meeting of the Directors or of a committee of Directors (including any person acting as an alternate Director) shall, notwithstanding that it be afterwards discovered that there was some defect in the appointment of any Director or alternate Director, or that they or any of them were disqualified, be as valid as if every such person had been duly appointed and qualified to be a Director or alternate Director as the case may be. 92. Members of the Board of Directors or of any committee thereof may participate in a meeting of the Board or of such committee by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other and participation in a meeting pursuant to this provision shall constitute presence in person at such meeting. A resolution in writing (in one or more counterparts), signed by all the Directors for the time being or all the members of a committee of Directors (an alternate Director being entitled to sign such resolution on behalf of his appointor) shall be as valid and effectual as if it had been passed at a meeting of the Directors or committee as the case may be duly convened and held. 93. (a) A Director may be represented at any meetings of the Board of Directors by a proxy appointed by him in which event the presence or vote of the proxy shall for all purposes be deemed to be that of the Director. (b) The provisions of Articles 59-62 shall mutatis mutandis apply to the appointment of proxies by Directors. VACATION OF OFFICE OF DIRECTOR 94. The office of a Director shall be vacated: (a) if he gives notice in writing to the Company that he resigns the office of Director; (b) if he absents himself (without being represented by proxy or an alternate -22- Director appointed by him) from three consecutive meetings of the Board of Directors without special leave of absence from the Directors, and they pass a resolution that he has by reason of such absence vacated office; (c) if he dies, becomes bankrupt or makes any arrangement or composition with his creditors generally; (d) if he is found a lunatic or becomes of unsound mind. APPOINTMENT AND REMOVAL OF DIRECTORS 95. The Company may by ordinary resolution appoint any person to be a Director and may in like manner remove any Director and may in like manner appoint another person in his stead. 96. The Directors shall have power at any time and from time to time to appoint any person to be a Director, either to fill a casual vacancy or as an addition to the existing Directors but so that the total amount of Directors (exclusive of alternate Directors) shall not at any time exceed the number fixed in accordance with these Articles. PRESUMPTION OF ASSENT 97. A Director of the Company who is present at a meeting of the Board of Directors at which action on any Company matter is taken shall be presumed to have assented to the action taken unless his dissent shall be entered in the Minutes of the meeting or unless he shall file his written dissent from such action with the person acting as the Secretary of the meeting before the adjournment thereof or shall forward such dissent by registered mail to such person immediately after the adjournment of the meeting. Such right to dissent shall not apply to a Director who voted in favour of such action. SEAL 98. (a) The Company may, if the Directors so determine, have a Seal which shall, subject to paragraph (c) hereof, only be used by the authority of the Directors or of a committee of the Directors authorised by the Directors in that behalf and every instrument to which the Seal has been affixed shall be signed by one person who shall be either a Director or the Secretary or Secretary-Treasurer or some person appointed by the Directors for the purpose. (b) The Company may have a duplicate Seal or Seals each of which shall be a -23- facsimile of the Common Seal of the Company and, if the Directors so determine, with the addition on its face of the name of every place where it is to be used. (c) A Director, Secretary or other officer or representative or attorney may without further authority of the Directors affix the Seal of the Company over his signature alone to any document of the Company required to be authenticated by him under Seal or to be filed with the Registrar of Companies in the Cayman Islands or elsewhere wheresoever. OFFICERS 99. The Company may have a President, a Secretary or Secretary-Treasurer appointed by the Directors who may also from time to time appoint such other officers as they consider necessary, all for such terms, at such remuneration and to perform such duties, and subject to such provisions as to disqualification and removal as the Directors from time to time prescribe. DIVIDENDS, DISTRIBUTIONS AND RESERVE 100. Subject to the Statute, the Directors may from time to time declare dividends (including interim dividends) and distributions on shares of the Company outstanding and authorise payment of the same out of the funds of the Company lawfully available therefor. 101. The Directors may, before declaring any dividends or distributions, set aside such sums as they think proper as a reserve or reserves which shall at the discretion of the Directors, be applicable for any purpose of the Company and pending such application may, at the like discretion, be employed in the business of the Company. 102. No dividend or distribution shall be payable except out of the profits of the Company, realised or unrealised, or out of the share premium account or as otherwise permitted by the Statute. 103. Subject to the rights of persons, if any, entitled to shares with special rights as to dividends or distributions, if dividends or distributions are to be declared on a class of shares they shall be declared and paid according to the amounts paid or credited as paid on the shares of such class outstanding on the record date for such dividend or distribution as determined in accordance with these Articles but no amount paid or credited as paid on a share in advance of calls shall be treated for the purpose of this Article as paid on the share. 104. The Directors may deduct from any dividend or distribution payable to any Member all sums of money (if any) presently payable by him to the Company on account of calls or otherwise. -24- 105. The Directors may declare that any dividend or distribution be paid wholly or partly by the distribution of specific assets and in particular of paid up shares, debentures, or debenture stock of any other company or in any one or more of such ways and where any difficulty arises in regard to such distribution, the Directors may settle the same as they think expedient and in particular may issue fractional certificates and fix the value for distribution of such specific assets or any part thereof and may determine that cash payments shall be made to any Members upon the footing of the value so fixed in order to adjust the rights of all Members and may vest any such specific assets in trustees as may seem expedient to the Directors. 106. Any dividend, distribution, interest or other monies payable in cash in respect of shares may be paid by cheque or warrant sent through the post directed to the registered address of the holder or, in the case of joint holders, to the holder who is first named on the register of Members or to such person and to such address as such holder or joint holders may in writing direct. Every such cheque or warrant shall be made payable to the order of the person to whom it is sent. Any one of two or more joint holders may give effectual receipts for any dividends, bonuses, or other monies payable in respect of the share held by them as joint holders. 107. No dividend or distribution shall bear interest against the Company. CAPITALISATION 108. The Company may upon the recommendation of the Directors by ordinary resolution authorise the Directors to capitalise any sum standing to the credit of any of the Company's reserve accounts (including share premium account and capital redemption reserve fund) or any sum standing to the credit of profit and loss account or otherwise available for distribution and to appropriate such sum to Members in the proportions in which such sum would have been divisible amongst them had the same been a distribution of profits by way of dividend and to apply such sum on their behalf in paying up in full unissued shares for allotment and distribution credited as fully paid up to and amongst them in the proportion aforesaid. In such event the Directors shall do all acts and things required to give effect to such capitalisation, with full power to the Directors to make such provisions as they think fit for the case of shares becoming distributable in fractions (including provisions whereby the benefit of fractional entitlements accrue to the Company rather than to the Members concerned). The Directors may authorise any person to enter on behalf of all of the Members interested into an agreement with the Company providing for such capitalisation and matters incidental thereto and any agreement made under such authority shall be effective and binding on all concerned. -25- BOOKS OF ACCOUNT 109. The Directors shall cause proper books of account to be kept with respect to: (a) all sums of money received and expended by the Company and the matters in respect of which the receipt or expenditure takes place; (b) all sales and purchases of goods by the Company; (c) the assets and liabilities of the Company. Proper books shall not be deemed to be kept if there are not kept such books of account as are necessary to give a true and fair view of the state of the Company's affairs and to explain its transactions. 110. The Directors shall from time to time determine whether and to what extent and at what times and places and under what conditions or regulations the accounts and books of the Company or any of them shall be open to the inspection of Members not being Directors and no Member (not being a Director) shall have any right of inspecting any account or book or document of the Company except as conferred by Statute or authorised by the Directors or by the Company in general meeting. 111. The Directors may from time to time cause to be prepared and to be laid before the Company in general meeting profit and loss accounts, balance sheets, group accounts (if any) and such other reports and accounts as may be required by law. AUDIT 112. The Company may at any annual general meeting appoint an Auditor or Auditors of the Company who shall hold office until the next annual general meeting and may fix his or their remuneration. 113. The Directors may before the first annual general meeting appoint an Auditor or Auditors of the Company who shall hold office until the first annual general meeting unless previously removed by an ordinary resolution of the Members in general meeting in which case the Members at that meeting may appoint Auditors. The Directors may fill any casual vacancy in the office of Auditor but while any such vacancy continues the surviving or continuing Auditor or Auditors, if any, may act. The remuneration of any Auditor appointed by the Directors under this Article may be fixed by the Directors. 114. Every Auditor of the Company shall have a right of access at all times to the -26- books and accounts and vouchers of the Company and shall be entitled to require from the Directors and Officers of the Company such information and explanation as may be necessary for the performance of the duties of the auditors. 115. Auditors shall at the next annual general meeting following their appointment and at any other time during their term of office, upon request of the Directors or any general meeting of the Members, make a report on the accounts of the Company in general meeting during their tenure of office. NOTICES 116. Notices shall be in writing and may be given by the Company to any Member either personally or by sending it by post, cable, telex or telecopy to him or to his address as shown in the register of Members, such notice, if mailed, to be forwarded airmail if the address be outside the Cayman Islands. 117. (a) Where a notice is sent by post, service of the notice shall be deemed to be effected by properly addressing, pre-paying and posting a letter containing the notice, and to have been effected at the expiration of sixty hours after the letter containing the same is posted as aforesaid. (b) Where a notice is sent by cable, telex, or telecopy, service of the notice shall be deemed to be effected by properly addressing, and sending such notice through a transmitting organisation and to have been effected on the day the same is sent as aforesaid. 118. A notice may be given by the Company to the joint holders of record of a share by giving the notice to the joint holder first named on the register of Members in respect of the share. 119. A notice may be given by the Company to the person or persons which the Company has been advised are entitled to a share or shares in consequence of the death or bankruptcy of a Member by sending it through the post as aforesaid in a pre-paid letter addressed to them by name, or by the title of representatives of the deceased, or trustee of the bankrupt, or by any like description at the address supplied for that purpose by the persons claiming to be so entitled, or at the option of the Company by giving the notice in any manner in which the same might have been given if the death or bankruptcy had not occurred. 120. Notice of every general meeting shall be given in any manner hereinbefore authorised to: (a) every person shown as a Member in the register of Members as of the record -27- date for such meeting except that in the case of joint holders the notice shall be sufficient if given to the joint holder first named in the register of Members; and (b) every person upon whom the ownership of a share devolves by reason of his being a legal personal representative or a trustee in bankruptcy of a Member of record where the Member of record but for his death or bankruptcy would be entitled to receive notice of the meeting. No other person shall be entitled to receive notices of general meetings. WINDING UP 121. If the Company shall be wound up the liquidator may, with the sanction of a Special Resolution of the Company and any other sanction required by the Statute, divide amongst the Members in specie or kind the whole or any part of the assets of the Company (whether they shall consist of property of the same kind or not) and may for such purpose set such value as he deems fair upon any property to be divided as aforesaid and may determine how such division shall be carried out as between the Members or different classes of Members. The liquidator may with the like sanction, vest the whole or any part of such assets in trustees upon such trusts for the benefit of the contributories as the liquidator, with the like sanction, shall think fit, but so that no Member shall be compelled to accept any shares or other securities whereon there is any liability. 122. If the Company shall be wound up, and the assets available for distribution amongst the Members as such shall be insufficient to repay the whole of the paid-up capital, such assets shall be distributed so that, as nearly as may be, the losses shall be borne by the Members in proportion to the capital paid up, or which ought to have been paid up, at the commencement of the winding up on the shares held by them respectively. And if in a winding up the assets available for distribution amongst the Members shall be more than sufficient to repay the whole of the capital paid up at the commencement of the winding up, the excess shall be distributed amongst the Members in proportion to the capital paid up at the commencement of the winding up on the shares held by them respectively. This Article is to be without prejudice to the rights of the holders of shares issued upon special terms and conditions. -28- INDEMNITY 123. The Directors and officers for the time being of the Company and any trustee for the time being acting in relation to any of the affairs of the Company and their heirs, executors, administrators and personal representatives respectively shall be indemnified out of the assets of the Company from and against all actions, proceedings, costs, charges, losses, damages and expenses which they or any of them shall or may incur or sustain by reason of any act done or omitted in or about the execution of their duty in their respective offices or trusts, except such (if any) as they shall incur or sustain by or through their own wilful neglect or default respectively and no such Director, officer or trustee shall be answerable for the acts, receipts, neglects or defaults of any other Director, officer or trustee or for joining in any receipt for the sake of conformity or for the solvency or honesty of any banker or other persons with whom any monies or effects belonging to the Company may be lodged or deposited for safe custody or for any insufficiency of any security upon which any monies of the Company may be invested or for any other loss or damage due to any such cause as aforesaid or which may happen in or about the execution of his office or trust unless the same shall happen through the wilful neglect or default of such Director, Officer or trustee. FINANCIAL YEAR 124.

"Consolidated Fixed Charge Coverage Ratio" means, with respect to any person, the ratio of Consolidated EBITDA of such person during the four full fiscal quarters (the "Four Quarter Period") ending on or prior to the date of the transaction giving rise to the need to calculate the Consolidated Fixed Charge Coverage Ratio (the "Transaction Date") to Consolidated Fixed Charges of such person for the Four Quarter Period. For purposes of this definition, if the Transaction Date occurs prior to the date on which four full fiscal quarters have elapsed subsequent to the Issue Date and financial statements with respect thereto are available, "Consolidated EBITDA" and "Consolidated Fixed Charges" shall be calculated, in the case of the Company, after giving effect on a pro forma basis to the issuance of the Securities and the application of the net proceeds therefrom including the redemption of the Company's outstanding preferred stock on the Issue Date as if the Securities were issued on the first day of the Four Quarter Period. In addition to and without limitation of the foregoing, for purposes of this definition, "Consolidated EBITDA" and "Consolidated Fixed Charges" shall be calculated after giving effect on a pro forma basis for the period of such calculation to (i) the incurrence of any Indebtedness (and the application of the net proceeds therefrom) of such person or any of its Subsidiaries (Restricted Subsidiaries, in the case of the Company) giving rise to the need to make such calculation and any incurrence of other Indebtedness at any time on or after the first day of the Four Quarter Period and on or prior to the Transaction Date (the "Reference Period"), as if such incurrence occurred on the first day of the Reference Period and (ii) any Asset Sales or Asset Acquisitions (including, without -7- limitation, any Asset Acquisition giving rise to the need to make such calculation as a result of such person or one of its Subsidiaries (Restricted Subsidiaries, in the case of the Company)(including any person who becomes a Subsidiary (Restricted Subsidiary, in the case of the Company) as a result of the Asset Acquisition) incurring, assuming or otherwise being liable for Acquired Indebtedness) occurring during the Reference Period, as if such Asset Sale or Asset Acquisition (including the incurrence, assumption or liability for any such Indebtedness or Acquired Indebtedness) occurred on the first day of the Reference Period. If such person or any of its Subsidiaries (Restricted Subsidiaries, in the case of the Company) directly or indirectly guarantees Indebtedness of a third person, the preceding sentence shall give effect to the incurrence of such guaranteed Indebtedness as if such person or any Subsidiary (Restricted Subsidiary, in the case of the Company) of such person had directly incurred or otherwise assumed such guaranteed Indebtedness.

ARTICLE TWO THE SECURITIES SECTION 2.01. Form and Dating. The Securities and the Trustee's certificate of authentication with respect thereto shall be substantially in the form of Exhibit A, Exhibit A-1, Exhibit B or Exhibit B-1 hereto, as the case may be. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage. The Company and the Trustee shall approve the form of the Securities and any notation, legend or endorsement on them. Each Security shall be dated the date of its authentication, shall bear interest from the applicable date and shall be payable on the Interest Payment Dates and the Maturity Date. Each Security shall have an executed Guarantee from each of the Guarantors endorsed thereon substantially in the form of Exhibit M hereto. The terms and provisions contained in the Securities shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. Securities offered and sold in their initial distribution in reliance on Regulation S may be initially issued in the form of temporary Global Securities in fully registered form without interest coupons, substantially in the form of Exhibit A or Exhibit A-1, as applicable, with such applicable legends as are provided for in Exhibit A, Exhibit A-1 or Exhibit C. Such temporary Global Securities may be registered in the name of the Depository or its nominee and deposited with the Trustee, as custodian for the Depository, duly executed by -26- the Company and authenticated by the Trustee as hereinafter provided (and the Guarantors shall execute the Guarantees thereon), for credit by the Depository to the respective accounts of the beneficial owners of the Securities represented thereby (or such other accounts as they may direct), provided that upon such deposit all such Securities shall be credited to or through accounts maintained at the Depository by or on behalf of Euroclear or CEDEL. Until such time as the Restricted Period (as defined below) shall have expired, such temporary Global Securities, together with their Successor Securities which are Global Securities other than the Restricted Global Security, shall be referred to herein as a "Temporary Regulation S Global Security." After such time as the Restricted Period shall have expired and the certifications referred to below in the next succeeding paragraph shall have been provided, interests in such Temporary Regulation S Global Securities shall be exchanged for interests in like Global Securities, referred to herein collectively as the "Permanent Regulation S Global Security," substantially in the form of Security set forth in Exhibit A or Exhibit A-1, as applicable, with such applicable legends as are provided for in Exhibit A, Exhibit A-1 or Exhibit C. Such Permanent Regulation S Global Securities shall be registered in the name of the Depository or its nominee and deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided, for credit to the respective accounts of the beneficial owners of the Securities represented thereby (or such other accounts as they may direct). The aggregate principal amount of the Temporary Regulation S Global Security or the Permanent Regulation S Global Security may be increased or decreased from time to time by adjustments made on the records of the Trustee, as custodian for the Depository, as hereinafter provided. As used herein, the term "Restricted Period" means the period of 40 days commencing on the day after the latest of (a) the day on which the Securities are first offered to persons other than distributors (as defined in Regulation S) in reliance on Regulation S and (b) the date of this Indenture. Interests in a Temporary Regulation S Global Security may be exchanged for interests in a Permanent Regulation S Global Security only after (a) the expiration of the Restricted Period, (b) delivery by a beneficial owner of an interest therein to Euroclear or CEDEL of a written certification (an "Owner Securities Certification") substantially in the form of Annex E hereto, and (c) upon delivery by Euroclear or CEDEL to the Trustee of a written certification (a "Depository Securities Certification") substantially in the form attached hereto as Exhibit F. Upon satisfaction of such conditions, the Trustee will exchange the portion of the Temporary Regulation S -27- Global Security covered by such certification for interests in a Permanent Regulation S Global Security. The delivery by such Holder of a beneficial interest in such Temporary Regulation S Global Security of such certification shall constitute an irrevocable instruction by such holder to Euroclear or CEDEL, as the case may be, to exchange such Holder's beneficial interest in the Temporary Regulation S Global Security for a beneficial interest in the Permanent Regulation S Global Security upon the expiration of the Restricted Period in accordance with the next succeeding paragraph. Upon: (i) the expiration of the Restricted Period; (ii) receipt by Euroclear or CEDEL, as the case may be, of Owner Securities Certifications described in the preceding paragraph; (iii) receipt by the Depository of: (1) written instructions given in accordance with the Applicable Procedures from an Agent Member directing the Depository to credit or cause to be credited to a specified Agent Member's account a beneficial interest in a Permanent Regulation S Global Security in a principal amount equal to that of the beneficial interest in a corresponding Temporary Regulation S Global Security for which the necessary certifications have been delivered; and (2) a written order given in accordance with the Applicable Procedures containing information regarding the account of the Agent Member, and the Euroclear or CEDEL account for which such Agent Member's account is held, to be credited with, and the account of the Agent Member to be debited for, such beneficial interest; and (iv) receipt by the Trustee of notification from the Depository of the transactions described in (iii) above and from Euroclear or CEDEL, as the case may be, of Depository Securities Certifications, the Trustee, as Registrar, shall instruct the Depository to reduce the principal amount of such Temporary Regulation S Global Security and to increase the principal amount of such Permanent Regulation S Global Security, by the principal amount of the beneficial interest in such Temporary Regulation S Global Security to be so transferred, and to credit or cause to be cred- -28- ited to the account of the person specified in such instructions a beneficial interest in such Permanent Regulation S Global Security having a principal amount equal to the amount by which the principal amount of such Temporary Regulation S Global Security was reduced upon such transfer. Securities offered and sold in their initial distribution in reliance on Rule 144A under the Securities Act and other than in reliance on Rule 144A under the Securities Act or Regulation S shall be issued in the form of one or more Global Securities (collectively, and, together with their Successor Securities, the "Restricted Global Security") in fully registered form without interest coupons, substantially in the form of Security set forth in Exhibit A or Exhibit A-1, as applicable, with such applicable legends as are provided for in Exhibit A, Exhibit A-1 or Exhibit C, except as otherwise permitted herein. Such Restricted Global Security shall be registered in the name of the Depository or its nominee and deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided, for credit by the Depository to the respective accounts of beneficial owners of the Securities represented thereby (or such other accounts as they may direct). The aggregate principal amount of the Restricted Global Security may be increased or decreased from time to time by adjustments made on the records of the Trustee, as custodian for the Depository, in connection with a corresponding decrease or increase in the aggregate principal amount of the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as hereinafter provided. SECTION 2.02. Execution and Authentication. Two Officers, or an Officer and an Assistant Secretary, shall sign, or one Officer shall sign and one Officer or an Assistant Secretary for the Company and each Guarantor (each of whom shall, in each case, have been duly authorized by all requisite corporate actions) shall attest to, the Securities for the Company and the Guarantees for the Guarantors by manual or facsimile signature. If an Officer whose signature is on a Security or a Guarantee was an Officer at the time of such execution but no longer holds that office at the time the Trustee authenticates the Security, the Security shall nevertheless be valid. A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclu- -29- sive evidence that the Security has been authenticated under this Indenture. The Trustee shall authenticate (i) Series A Fixed Rate Notes for original issue in the aggregate principal amount not to exceed $200,000,000, (ii) Series A Floating Rate Notes for original issue in the aggregate principal amount not to exceed $55,000,000 and (iii) one or more series of Fixed Rate Notes and one or more series of Floating Rate Notes for original issue after the Issue Date (such Notes to be substantially in the form of Exhibits A or A-1, as the case may be, or Exhibits B or B-1, as the case may be) in an aggregate principal amount not to exceed $100,000,000 (and if in the form of Exhibit A or A-1, as the case may be, the same principal amount of Securities in exchange therefor upon consummation of a registered exchange offer) in each case, upon written orders of the Company in the form of an Officers' Certificate. In each case, the Officers' Certificate shall specify the amount of Securities to be authenticated and the date on which the Securities are to be authenticated and the aggregate principal amount of Securities outstanding on the date of authentication whether the Securities are to be Series A Notes, Series B Notes or Securities issued under clause (iii) of the preceding sentence and shall further specify the amount of such Securities to be issued as a Global Security or in certificated form. The aggregate principal amount of Securities outstanding at any time may not exceed $355,000,000, except as provided in Section 2.07. Upon the written order of the Company in the form of an Officers' Certificate, the Trustee shall authenticate Securities in substitution of Securities originally issued to reflect any name change of the Company. Series B Notes may be issued only in exchange for a like principal amount of Series A Notes pursuant to an Exchange Offer. The principal and interest on Book-Entry Securities shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole holder of the Book-Entry Securities represented thereby. The principal and interest on Securities in certificated form shall be payable at the office of the Paying Agent. The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Securities. Unless otherwise provided in the appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticat- -30- ing agent has the same rights as an Agent to deal with the Company and Affiliates of the Company. The Securities shall be issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. If the Securities are to be issued in the form of one or more Global Securities, then the Company shall execute and the Trustee shall authenticate and deliver one or more Global Securities that shall represent and shall be in minimum denominations of $1,000. SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an office or agency in the Borough of Manhattan, The City of New York, where (a) Securities may be presented or surrendered for registration of transfer or for exchange ("Registrar"), (b) Securities may be presented or surrendered for payment ("Paying Agent") and (c) notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. Neither the Company nor any Affiliate of the Company shall act as Paying Agent. The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company, upon notice to the Trustee, may have one or more co-Registrars and one or more additional paying agents reasonably acceptable to the Trustee. The term "Paying Agent" includes any additional paying agent. The Company initially appoints the Trustee as Registrar and Paying Agent until such time as the Trustee has resigned or a successor has been appointed. The initial office of the Company and the Trustee for purposes of this Section 2.03 shall be State Street Bank and Trust Company, N.A., 61 Broadway, 15th Floor, NY, NY 10006. The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee, in advance, of the name and address of any such Agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such. -31- SECTION 2.04. Paying Agent To Hold Assets in Trust. The Company shall require each Paying Agent other than the Trustee to agree in writing that each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all assets held by the Paying Agent for the payment of principal of, or interest on, the Securities (whether such assets have been distributed to it by the Company or any other obligor on the Securities), and shall notify the Trustee of any Default by the Company (or any other obligor on the Securities) in making any such payment. The Company at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to distribute all assets held by it to the Trustee and to account for any assets distributed. Upon distribution to the Trustee of all assets that shall have been delivered by the Company to the Paying Agent, the Paying Agent shall have no further liability for such assets. SECTION 2.05. Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee before each Record Date and at such other times as the Trustee may request in writing a list as of such date and in such form as the Trustee may reasonably require of the names and addresses of the Holders, which list may be conclusively relied upon by the Trustee. SECTION 2.06. Transfer and Exchange. (a) Beneficial interests in a Global Security may, subject to the restrictions on the transferability of the Securities and upon delivery of a certificate in the form of Exhibit D, be exchanged for certificated Securities upon request but only upon at least 20 days' prior written notice given to the Trustee by or on behalf of the Depository (in accordance with the Depository's customary procedures) and will bear the applicable legends set forth in Exhibit A or Exhibit A-1, as applicable. (b) If any Global Security is to be exchanged for other Securities or cancelled in whole, it shall be surrendered by or on behalf of the Depository or its nominee to the Trustee, as Registrar, for exchange or cancellation as provided in this Article II. If any Global Security is to be exchanged for -32- other Securities or cancelled in part, or if another Security is to be exchanged in whole or in part for a beneficial interest in any Global Security, such Global Security shall be so surrendered for exchange or cancellation as provided in this Article II or, if the Trustee is acting as custodian for the Depository or its nominee (or is party to a similar arrangement) with respect to such Global Security, the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or cancelled, or the principal amount of such other Security to be so exchanged for a beneficial interest therein, as the case may be, in each case by means of an appropriate adjustment made on the records of the Trustee, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depository or its authorized representatives to make a corresponding adjustment to its records (including by crediting or debiting any Agent Member's account as necessary to reflect any transfer or exchange of a beneficial interest). Upon any such surrender or adjustment of a Global Security, the Trustee shall, subject to this Article II, authenticate and deliver any Securities (and the Guarantors shall execute the Guarantees thereon) issuable in exchange for such Global Security (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depository or its authorized representative and each of the Guarantors shall execute a Guarantee thereon at the Trustee's request. Upon the request of the Trustee in connection with the occurrence of any of the events specified in the preceding paragraph or in paragraph (r) below, the Company shall promptly make available to the Trustee a reasonable supply of Securities that are not in the form of Global Securities. The Trustee shall be entitled to rely upon any order, direction or request of the Depository or its authorized representative which is given or made pursuant to this Article II if such order, direction or request is given or made in accordance with the Applicable Procedures, as certified to the Trustee by the Depository. (c) Subject to the provisions in the legends required by this Indenture, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and Persons who may hold interests in Agent Members, to take any action that such Holder is entitled to take under this Indenture. (d) Neither Agent Members nor any other Person on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security held on their behalf by the Depository or under the Global Security, and the Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute -33- owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security. With respect to any Global Security deposited with the Trustee as custodian for the Depository for credit to their respective accounts (or to such other accounts as they may direct) at Euroclear or CEDEL, the provisions of the "Operating Procedures of the Euroclear System" and the "Terms and Conditions Governing Use of Euroclear", and the "Management Regulations" and "Instructions to Participants" of CEDEL, respectively, shall be applicable to such Global Security, as certifies to the Trustee by Euroclear or CEDEL, as applicable. (e) Upon presentation for transfer or exchange of any Security at the office of the Trustee, as Registrar, located in The City of New York, accompanied by a written instrument of transfer or exchange in the form approved by the Company (it being understood that, until notice to the contrary is given to holders of Securities, the Company shall be deemed to have approved the form of instrument of transfer or exchange, if any, printed on any Security), executed by the registered Holder, in person or by such Holder's attorney thereunto duly authorized in writing, and upon compliance with this Section 2.06, such Security shall be transferred upon the Register, and a new Security shall be authenticated and issued in the name of the transferee and the Guarantors shall execute Guarantees thereon. Notwithstanding any provision to the contrary herein or in the Securities, transfers of a Global Security, in whole or in part, and transfers of interests therein of the kind described in this Section 2.06, shall only be made in accordance with this Section 2.06. Transfers and exchanges subject to this Section 2.06 shall also be subject to the other provisions of this Indenture that are not inconsistent with this Section 2.06. (f) General. A Global Security may not be transferred, in whole or in part, to any Person other than the Depository or a nominee thereof, and no such transfer to any such other Person may be registered; provided, however, that this clause (f) shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Nothing in this clause (f) shall prohibit or render ineffective any transfer of a beneficial interest in a Global -34- Security effected in accordance with the other provisions of this Section 2.06. (g) Temporary Regulation S Global Security. If the holder of a beneficial interest in a Temporary Regulation S Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in such Temporary Regulation S Global Security, such transfer may be effected, subject to the rules and procedures of the Depository, Euroclear and CEDEL, in each case to the extent applicable and as in effect from time to time (the "Applicable Procedures"), only in accordance with this clause (g). Upon delivery (i) by a beneficial owner of an interest in a Temporary Regulation S Global Security to Euroclear or CEDEL, as the case may be, of an Owner Securities Certification, (ii) by the transferee of such beneficial interest in the Temporary Regulation S Global Security to Euroclear or CEDEL, as the case may be, of a written certification (a "Transferee Securities Certification") substantially in the form of Exhibit G hereto and (iii) by Euroclear or CEDEL, as the case may be, to the Trustee, as Registrar, of a Depository Securities Certification, the Trustee may direct either Euroclear or CEDEL, as the case may be, to reflect on its records the transfer of a beneficial interest in the Temporary Regulation S Global Security from the beneficial owner providing the Owner Securities Certification to the Person providing the Transferee Securities Certification. (h) Restricted Global Security to Temporary Regulation S Global Security. If the holder of a beneficial interest in the Restricted Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Temporary Regulation S Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with the provisions of this clause (h) and clause (n) below.

(j) Temporary Regulation S Global Security or Permanent Regulation S Global Security to Restricted Global Security. If the holder of a beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security at any time, wishes to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this clause (j) and clause (n) below; provided that with respect to any transfer of a beneficial interest in a Temporary Regulation S Global Security, the transferor and Euroclear or CEDEL, as the case may be, must have previously delivered an Owner Securities Certification and a Depository Securities Certification respectively, with respect to such beneficial interest. Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depository in accordance with the Applicable Procedures directing the Trustee to credit or cause to be credited to a specified Agent Member's account a beneficial interest in the Restricted Global Security in a specified principal amount and to cause to be debited from another specified Agent Member's account a beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as the case may be, in an equal principal amount and (B) a cer- -36- tificate in substantially the form set forth in Exhibit J signed by or on behalf of the holder of such beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as the case may be, the Trustee, as Security Registrar, shall, subject to clause (n) below, reduce the principal amount of such Temporary Regulation S Global Security or Permanent Regulation S Global Security, as the case may be, and increase the principal amount of the Restricted Global Security by such specified principal amount.

To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities (and the Guarantors shall execute the Guarantors thereon) at the Registrar's or co-Registrar's request. No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Sections 2.02, 2.10, 3.07, 4.15, 4.16 or 9.05). The Registrar or co-Registrar shall not be required to register the transfer of or exchange of any Security (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Securities and ending at the close of business on the day of such mailing and (ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Security being redeemed in part. (p) If a Series A Note is a Restricted Security in certificated form, then as provided in this Indenture and subject to the limitations herein set forth, the Holder, provided it is a Qualified Institutional Buyer, may exchange such Security for a Book-Entry Security by instructing the Trustee (by completing the Transferee Certificate in the form of Exhibit D hereto) to arrange for such Series A Note to be represented by a beneficial interest in a Global Security in accordance with the customary procedures of the Depository. (q) Upon any exchange provided for in Section 2.06(a), the Company shall execute and the Trustee shall authenticate and deliver to the person specified by the Depository a new Series A Note or Series A Notes registered in such names and in such authorized denominations as the Depository, pursuant to the instructions of the beneficial owner of the Securities requesting the exchange, shall instruct the Trustee. Thereupon, the beneficial ownership of such Global Security shown on the records maintained by the Depository or its nominee shall be reduced by the amounts so exchanged and an appropriate endorsement shall be made by or on behalf of the Trustee on the Global Security. Any such exchange shall be effected -39- through the Depository in accordance with the procedures of the Depository therefor. (r) Notwithstanding the foregoing, no Global Security shall be registered for transfer or exchange, or authenticated and delivered, whether pursuant to this Section, Section 2.07, 2.10 or 3.07 or otherwise, in the name of a person other than the Depository for such Global Security or its nominee until (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time the Depository ceases to be a clearing agency registered under the Exchange Act, and a successor depository is not appointed by the Company within 30 days, (ii) the Company executes and delivers to the Trustee a Company order that all such Global Securities shall be exchangeable or (iii) there shall have occurred and be continuing an Event of Default. Upon the occurrence in respect of any Global Security representing the Series A Notes of any one or more of the conditions specified in clause (i), (ii) or (iii) of the preceding sentence, such Global Security may be registered for transfer or exchange for Series A Notes registered in the names of, authenticated and delivered to such persons as the Trustee or the Depository, as the case may be, shall direct. (s) Except as provided above, any Security authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, any Global Security, whether pursuant to this Section, Section 2.07, 2.10 or 3.07 or otherwise, shall also be a Global Security and bear the legend specified in Exhibit C. SECTION 2.07. Replacement Securities. If a mutilated Security is surrendered to the Trustee or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security (and the Guarantors shall execute the Guarantees thereon) if the Trustee's requirements are met. If required by the Trustee or the Company, such Holder must provide an indemnity bond or other indemnity, sufficient in the judgment of the Company, the Guarantors and the Trustee, to protect the Company, the Guarantors, the Trustee or any Agent from any loss which any of them may suffer if a Security is replaced. The Company may charge such Holder for its reasonable out-of-pocket expenses in replacing a Security, including reasonable fees and expenses of counsel. Every replacement Security shall constitute an additional obligation of the Company and the Guarantors. -40- SECTION 2.08. Outstanding Securities. Securities outstanding at any time are all the Securities that have been authenticated by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or any of its Affiliates holds the Security. If a Security is replaced pursuant to Section 2.07 (other than a mutilated Security surrendered for replacement), it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. A mutilated Security ceases to be outstanding upon surrender of such Security and replacement thereof pursuant to Section 2.07. If on a Redemption Date or the Maturity Date the Paying Agent holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the principal and interest due on the Securities payable on that date, then on and after that date such Securities cease to be outstanding and interest on them ceases to accrue; provided, however, that to the extent the Trustee is enjoined from making payments to the Holders, interest will continue to accrue until such time as the Trustee is not so enjoined. SECTION 2.09. Treasury Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or an Affiliate of the Company shall be disregarded, except that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities that the Trustee knows are so owned shall be disregarded. SECTION 2.10. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities (and the Guarantors shall execute the guarantees thereon) upon receipt of a written order of the Company in the form of an Officers' Certificate. The Officers' Certificate shall specify the amount of temporary Securities to be authenticated and the date on which the temporary Securities are to be authenticated. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary -41- Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and the Guarantors shall execute Guarantees on, upon receipt of a written order of the Company pursuant to Section 2.02, definitive Securities in exchange for temporary Securities. SECTION 2.11. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel and, at the written direction of the Company, shall dispose of all Securities surrendered for transfer, exchange, payment or cancellation. Subject to Section 2.07, the Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. SECTION 2.12. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, it shall, unless the Trustee fixes another record date pursuant to Section 6.10, pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest to the persons who are Holders on a subsequent special record date, which date shall be the fifteenth day next preceding the date fixed by the Company for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 15 days before the subsequent special record date, the Company shall mail to each Holder, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. SECTION 2.13. CUSIP Number. The Company in issuing the Securities may use a CUSIP number or numbers, and if so, the Trustee shall use the CUSIP number or numbers in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number or numbers printed in the notice or on -42- the Securities, and that reliance may be placed only on the other identification numbers printed on the Securities. SECTION 2.14. Designation. The Indebtedness evidenced by the Securities and the Guarantees is hereby irrevocably designated as "senior indebtedness" or such other term denoting seniority (i) for all purposes of the provisions defining subordination contained in agreements that provide that the Indebtedness of the Company issued pursuant to such agreements is subordinate to Indebtedness designated as senior indebtedness and (ii) for the purposes of any future Indebtedness of the Company which the Company expressly makes subordinate to any senior indebtedness or such other term denoting seniority. In connection with the issuance of any such future subordinated Indebtedness, the Company shall take all necessary steps to effectuate the foregoing. ARTICLE THREE REDEMPTION SECTION 3.01. Optional Redemption. (a) The Fixed Rate Notes will be subject to redemption, in whole or in part, at the option of the Company, at any time on or after March 15, 2002, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued interest to the redemption date, if redeemed during the 12 month period beginning on March 15 of the years indicated below: Year Percentage 2002...................................... 105.625% 2003...................................... 102.813% 2004 and thereafter....................... 100.000% (b) The Floating Rate Notes will be subject to redemption, in whole at any time or in part from time to time, at the option of the Company, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued interest to the redemption date, if redeemed during the twelve month period beginning on March 15 of the years indicated below: -43- Year Percentage 1998...................................... 104.000% 1999...................................... 103.000% 2000...................................... 102.000% 2001...................................... 101.000% 2002 and thereafter....................... 100.000% (c) In addition, at any time prior to March 15, 2001, the Company may redeem up to 35% of the sum of (x) the aggregate principal amount of the Fixed Rate Notes issued in the Offering plus (y) any additional Fixed Rate Notes issued after the Issue Date pursuant to this Indenture, with the proceeds of one or more Equity Offerings at a redemption price (expressed as a percentage of principal amount) of 111.25% plus accrued interest to the redemption date; PROVIDED that at least 65% of the sum of (x) the aggregate principal amount of Fixed Rate Notes issued in the Offering plus (y) any additional Fixed Rate Notes issued after the Issue Date pursuant to this Indenture remains outstanding immediately after any such redemption. In order to effect the foregoing redemption with the proceeds of any Equity Offering, the Company shall make such redemption not more than 120 days after the consummation of any such Equity Offering. SECTION 3.02. Notices to Trustee. If the Company elects to redeem Securities pursuant to this Indenture and the Securities, it shall notify the Trustee and the Paying Agent in writing of the Redemption Date and the principal amount of the Securities to be redeemed and whether it wants the Trustee to give notice of redemption to the Holders (at the Company's expense) at least 30 days (unless a shorter notice shall be satisfactory to the Trustee) but not more than 60 days before the Redemption Date. Any such notice may be cancelled at any time prior to notice of such redemption being mailed to any Holder and shall thereby be void and of no effect. SECTION 3.03. Selection of Securities To Be Redeemed. If less than all of the Securities are to be redeemed at any time, the Trustee shall select the Securities to be redeemed in compliance with the requirements of the principal national securities exchange, if any, on which the Securities being redeemed are listed or, if the Securities are not listed on a national securities exchange, on a PRO RATA basis, by lot or by such other method as the Trustee shall deem fair and appropriate. -44- The Trustee shall make the selection from the Securities outstanding and not previously called for redemption and shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed. Securities in denominations of $1,000 or less may be redeemed only in whole. The Trustee may select for redemption portions (equal to $1,000 or any integral multiple thereof) of the principal of Securities that have denominations larger than $1,000. If a redemption is to be made with the proceeds of an Equity Offering pursuant to Section 3.01(c), selection of the Fixed Rate Notes for redemption shall be made by the Trustee only on a PRO RATA basis unless such method is otherwise prohibited. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. SECTION 3.04. Notice of Redemption. Except as otherwise provided in Section 3.01, at least 30 days but not more than 60 days before a Redemption Date the Company shall mail a notice of redemption by first class mail to each Holder whose Securities are to be redeemed, with a copy to the Trustee. At the Company's request, the Trustee shall give the notice of redemption in the Company's name and at the Company's expense. Each notice for redemption shall identify the Securities to be redeemed and shall state: (1) the Redemption Date; (2) the Redemption Price; (3) the name and address of the Paying Agent; (4) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price; (5) that, unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the Redemption Date, and the only remaining right of the Holders of such Securities is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Securities redeemed; (6) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the Redemption Date, and upon surrender of such Security, a new Security or Securities in -45- the aggregate principal amount equal to the unredeemed portion thereof will be issued; (7) if fewer than all the Securities are to be redeemed, the identification of the particular Securities (or portion thereof) to be redeemed, as well as the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities to be outstanding after such partial redemption; and (8) the CUSIP number, if any, relating to such Securities. SECTION 3.05. Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.04, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price. Upon surrender to the Trustee or Paying Agent, such Securities called for redemption shall be paid at the Redemption Price plus accrued interest to the Redemption Date, but interest installments whose maturity is on or prior to such Redemption Date will be payable on the relevant Interest Payment Dates to the Holders of record at the close of business on the relevant Record Dates referred to in the Securities. SECTION 3.06. Deposit of Redemption Price. On or before the Redemption Date, the Company shall deposit with the Paying Agent U.S. Legal Tender sufficient and timely to pay the Redemption Price of all Securities to be redeemed on that date (other than Securities or portions thereof called for redemption on that date which have been delivered by the Company to the Trustee for cancellation). The Paying Agent shall promptly return to the Company any U.S. Legal Tender so deposited which is not required for that purpose upon the written request of the Company, except with respect to monies owed as obligations to the Trustee pursuant to Article Seven. If the Company complies with the preceding paragraph, then, unless the Company defaults in the payment of such Redemption Price, interest on the Securities to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not such Securities are presented for payment. SECTION 3.07. Securities Redeemed in Part. Upon surrender of a Security that is to be redeemed in part, the Trustee shall authenticate for the Holder a new -46- Security or Securities equal in principal amount to the unredeemed portion of the Security surrendered. ARTICLE FOUR COVENANTS SECTION 4.01. Payment of Securities. The Company shall pay the principal of and interest on the Securities on the dates and in the manner provided in the Securities. An installment of principal of or interest on the Securities shall be considered paid on the date it is due if the Trustee or Paying Agent holds on that date U.S. Legal Tender designated for and sufficient and timely to pay the installment. Interest on the Fixed Rate Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months and interest on the Floating Rate Notes will be computed as set forth in Exhibit A-1 or Exhibit B-1, as applicable. The Company shall pay interest on overdue principal and (to the extent permitted by law) on overdue installments of interest at a rate equal to 13.25% PER ANNUM. SECTION 4.02. Maintenance of Office or Agency. The Company shall maintain in the Borough of Manhattan, The City of New York, the office or agency required under Section 2.03. The Company shall give prior notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 10.02. The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; PROVIDED, HOWEVER, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. -47- The Company hereby initially designates the office of State Street Bank and Trust Company, Goodwin Square, 225 Asylum, 23rd Floor, Hartford, CT 06103, as such office of the Company in accordance with this Section 4.02. SECTION 4.03. Limitation on Restricted Payments. The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, after the Issue Date (a) declare or pay any dividend or make any distribution on the Company's Capital Stock or make any payment to holders of such Capital Stock (other than dividends or distributions payable in Qualified Capital Stock of the Company), (b) purchase, redeem or otherwise acquire or retire for value any Capital Stock of the Company or any warrants, rights or options to purchase or acquire shares of any class of such Capital Stock, (c) purchase, redeem, prepay, defease or otherwise acquire or retire for value, prior to any scheduled maturity, scheduled repayment or scheduled sinking fund payment, Indebtedness of the Company or any of the Guarantors that is expressly subordinate in right of payment to the Securities or the Guarantee of such Guarantor, as the case may be, or (d) make any Investment (excluding any Permitted Investment) (each of the foregoing actions set forth in clauses (a), (b), (c) and (d) being referred to as a "Restricted Payment"), if at the time of such Restricted Payment or immediately after giving effect thereto,(i) a Default or an Event of Default shall have occurred and be continuing or (ii) Restricted Payments made subsequent to the Issue Date (the amount expended for such purposes, if other than in cash, shall be the Fair Market Value of such property proposed to be transferred by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment) shall exceed the sum of: (w) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss) of the Company earned subsequent to the Issue Date and prior to the date the Restricted Payment occurs (treating such period as a single accounting period); (x) 100% of the aggregate net proceeds, including the Fair Market Value of Property other than cash, received by the Company from any person (other than a Subsidiary of the Company) from the issuance and sale subsequent to the Issue Date of Qualified Capital Stock of the Company (excluding (A) Qualified Capital Stock paid as a dividend on any Capital Stock or as interest on any Indebtedness, (B) any net proceeds from issuances and sales financed directly or indirectly using funds borrowed from -48- the Company or any Subsidiary of the Company, until and to the extent such borrowing is repaid and (C) any net proceeds from any Equity Offering which are used to redeem Fixed Rate Notes pursuant to, and in accordance with, the provisions under Section 3.01(c).

Except as otherwise permitted by Article Five, each of the Company and the Guarantors shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate or other existence of each of its Subsidiaries in accordance with the respective organizational documents of each such Subsidiary and the rights (charter and statutory) and franchises of each of the Company and the Guarantors and each such Subsidiary; PROVIDED, HOWEVER, that each of the Company and the Guarantors shall not be required to preserve, with respect to itself, any right or franchise, and with respect to any of its Subsidiaries any such existence, right or franchise, if the Board of Directors of each of the Company and the Guarantors shall determine that the preservation thereof is no longer desirable in the conduct of the business of each of the Company and the Guarantors and will not be adverse in any material respect to the Holders. SECTION 4.05. Payment of Taxes and Other Claims. The Company shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all taxes, assessments and governmental charges (including withholding taxes and any penalties, interest and additions to taxes) levied or imposed upon it or any of its Subsidiaries or properties of it or any of its Subsidiaries and (ii) all lawful claims for labor, materials and supplies that, if unpaid, might by law become a Lien upon the property of it or any of its Subsidiaries; PROVIDED, HOWEVER, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim if either (a) the amount, applicability or validity thereof is being contested in -51- good faith by appropriate proceedings and an adequate reserve has been established therefor to the extent required by GAAP or (b) the failure to make such payment or effect such discharge (together with all other such failures) would not have a material adverse effect on the financial condition or results of operations of the Company and its Subsidiaries, taken as a whole. SECTION 4.06. Maintenance of Properties and Insurance. (a) Each of the Company and the Guarantors shall cause all properties used or useful in the conduct of its business or the business of any of its Subsidiaries to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in its judgment may be necessary, so that the business carried on in connection therewith may be properly and advantageously conducted at all times unless the failure to so maintain such properties (together with all other such failures) would not have a material adverse effect on the financial condition or results of operations of the Company and the Guarantors and their Subsidiaries taken as a whole; PROVIDED, HOWEVER, that nothing in this Section 4.06 shall prevent the Company and the Guarantors or any of their Subsidiaries from discontinuing the operation or maintenance of any of such properties, or disposing of any of them, if such discontinuance or disposal is either (i) in the ordinary course of business, (ii) in the good faith judgment of the Board of Directors of the Company or the Guarantors or the Subsidiary concerned, or of the senior officers of the Company or the Guarantors or such Subsidiary, as the case may be, desirable in the conduct of the business of the Company or the Guarantors or such Subsidiary, as the case may be, or (iii) is otherwise permitted by this Indenture.

SECTION 4.07. Compliance Certificate; Notice of Default. (a) The Company shall deliver to the Trustee, within 60 days after the end of the Company's fiscal quarters and within 90 days after the end of the Company's fiscal year, an Officers' Certificate stating that a review of its activities and the activities of its Subsidiaries during the preceding fiscal period has been made under the supervision of the signing Officers with a view to determining whether it has kept, observed, performed and fulfilled its obligations under this Indenture and further stating, as to each such Officer signing such certificate, that to the best of his knowledge, the Company during such preceding fiscal period has kept, observed, performed and fulfilled each and every such covenant and no Default or Event of Default occurred during such period and at the date of such certificate there is no Default or Event of Default that has occurred and is continuing or, if such signers do know of such Default or Event of Default, the certificate shall describe the Default or Event of Default and its status with particularity. The Officers' Certificate shall also include all calculations necessary to show covenant compliance. The Officers' Certificate shall also notify the Trustee should the Company elect to change the manner in which it fixes its fiscal year end.

(c) The Company will deliver to the Trustee as soon as possible, and in any event within 10 days after the Company becomes aware or should reasonably have become aware of the occurrence of any Default or Event of Default, an Officers' Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. -53- SECTION 4.08. Compliance with Laws. Each of the Company and the Guarantors shall comply, and shall cause each of its Subsidiaries to comply, with all applicable statutes, rules, regulations, orders and restrictions of the United States of America, Peru and the Cayman Islands, all states and municipalities thereof, and of any governmental department, commission, board, regulatory authority, bureau, agency and instrumentality of the foregoing, in respect of the conduct of their respective businesses and the ownership of their respective properties, except such as are being contested in good faith and by appropriate proceedings and except for such noncompliances as would not in the aggregate have a material adverse effect on the financial condition or results of operations of each of the Company and the Guarantors and its Subsidiaries taken as a whole. SECTION 4.09. SEC Reports and Other Information. (a) At all times when the Company is required or permitted voluntarily to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act or this Indenture is qualified under the TIA, the Company (at its own expense) shall file with the SEC and shall file with the Trustee and mail or cause the Trustee to mail to the Holders at their addresses set forth in the register of Securities within 15 days after it files them with the SEC copies of the annual reports, quarterly reports and the information, documents, and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) to be filed pursuant to Section 13 or 15(d) of the Exchange Act. If the Company is not subject to the requirements of such Section 13 or 15(d) of the Exchange Act and not permitted to voluntarily file and this Indenture has not been qualified under the TIA, the Company (at its own expense) shall file with the Trustee and mail or cause the Trustee to mail to the Holders at their addresses set forth in the register of Securities, within 15 days after it would have been required to file such information with the SEC, all information and financial statements, including any notes thereto and with respect to annual reports, quarterly reports, an auditors' report by an accounting firm of established national reputation, and a "Management's Discussion and Analysis of Financial Condition and Results of Operations," both comparable to the disclosure that each of the Company would have been required to include in such annual reports, quarterly reports, information, documents or other reports, as if the Company was subject to the requirements of such Section 13 or 15(d) of the Exchange Act, in each case in the form that would have been required by the SEC. Upon qualification of this Indenture under -54- the TIA, the Company shall also comply with the provisions of TIA ss. 314(a).

SECTION 4.10. Waiver of Stay, Extension or Usury Laws. Each of the Company and the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the each of Company and the Guarantors from paying all or any portion of the principal of or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) each of the Company and the Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. SECTION 4.11. Limitation on Transactions with Affiliates. (a) The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any transaction (including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of any service) with or for the benefit of an Affiliate of the Company or any Restricted Subsidiary (other than transactions between the Company and a Wholly-Owned Restricted Subsidiary or between Wholly-Owned Restricted Subsidiaries) (an "Affiliate Transaction"), other than (x) Affiliate Transactions permitted under (b) below and (y) Affiliate Transactions (including lease transactions) on terms that are no less favorable to the Company or the relevant Restricted Subsidiary in the aggregate than those that might reasonably have been obtained in a comparable transaction by the Company or such Restricted Subsidiary on an arm's-length basis (as determined in good faith by the Board of Directors of -55- the Company, as evidenced by a Board Resolution) from a person that is not an Affiliate; PROVIDED that except as otherwise provided under (b) below, neither the Company nor any of the Restricted Subsidiaries shall enter into an Affiliate Transaction or series of related Affiliate Transactions involving or having a value of more than $5.0 million unless the Company or such Restricted Subsidiary, as the case may be, has received an opinion from an Independent Financial Advisor, with a copy thereof to the Trustee, to the effect that the financial terms of such Affiliate Transaction are fair and reasonable to the Company or such Restricted Subsidiary, as the case may be, and such terms are no less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable transaction on an arm's-length basis with a person that is not an Affiliate. (b) The foregoing provisions shall not apply to (i) any Restricted Payment that is made in compliance with Section 4.03, (ii) payments by the Company or any of the Restricted Subsidiaries to Renco or DRA of the amounts set forth in clauses (4), (5), (6) and (7) of the second paragraph of Section 4.03 and (iii) reasonable and customary regular fees to directors of the Company and the Restricted Subsidiaries who are not employees of the Company and the Restricted Subsidiaries.

(b) The Company and the Guarantors shall not, directly or indirectly, in any event incur any Indebtedness which by its terms (or by the terms of any agreement governing such -56- Indebtedness) is subordinated to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinated to the Securities or the Guarantee of such Guarantor, as the case may be, to the same extent and in the same manner as such Indebtedness is subordinated to such other Indebtedness of the Company or such Guarantor. SECTION 4.13. Limitation on Dividends and Other Payment Restrictions Affecting Restricted Subsidiaries. The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to: (a) pay dividends or make any other distributions on its Capital Stock, or any other interest or participation in, or measured by, its profits, owned by the Company or by any Restricted Subsidiary, or pay any Indebtedness owed to the Company or any Restricted Subsidiary; (b) make loans or advances to the Company or any Restricted Subsidiary; or (c) transfer any of its properties or assets to the Company or to any Restricted Subsidiary, except, in each case, for such encumbrances or restrictions existing under or by reason of: (i) applicable law; (ii) this Indenture; (iii) customary non-assignment provisions of any lease governing a leasehold interest of the Company or any Restricted Subsidiary; (iv) any instrument governing Indebtedness of a person acquired by the Company or any Restricted Subsidiary at the time of such acquisition, which encumbrance or restriction is not applicable to any person, or the properties or assets of any person, other than the person or its Subsidiaries so acquired; (v) any written agreement existing on the Issue Date or amendments or modifications thereto, PROVIDED that no such agreement shall be modified or amended in such a manner as to make the encumbrance or restriction more restrictive than as in effect on the Issue Date; (vi) Indebtedness existing and as in effect on the Issue Date, including, without limitation, the U.S. Revolving Credit Facility or any refinancing, refunding, replacement or extensions thereof, PROVIDED that any such encumbrance or restriction contained in any refinancing, refunding, replacement or extension of the U.S. Revolving Credit Facility shall be no more restrictive than such encumbrance or restriction contained in the U.S. Revolving Credit Facility as in effect on the Issue Date; (vii) Indebtedness under the Peruvian Revolving Credit Facility or any refinancings, refundings, replacements or extensions thereof, PROVIDED that such restrictions do not prohibit payments pursuant to the intercompany agreements between -57- the Company and the Restricted Subsidiaries as in effect on the Issue Date or pursuant to any replacements thereof or pursuant to any comparable agreements thereto, in each case providing for the same or similar payments; and (viii) Indebtedness incurred in accordance with this Indenture, PROVIDED that such encumbrance or restriction shall be no more restrictive than any encumbrance or restriction contained in the Revolving Credit Facilities.

If an Event of Default (other than an Event of Default specified in Section 6.01(8) or 6.01(9)) occurs and is continuing, then and in every such case the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by written notice to the Company and the Trustee, and the Trus- -69- tee shall, upon the request of such Holders, declare the aggregate unpaid principal of and premium, if any, on all of the Securities outstanding, together with accrued but unpaid interest thereon to the date of payment, to be due and payable and, upon any such declaration, the same shall become and be due and payable; PROVIDED, HOWEVER, that the Trustee shall be under no obligation to follow any request of any of the Holders unless such Holders shall have offered to the Trustee, after request by the Trustee, reasonable security or indemnity against the costs, expenses and liabilities which may be incurred by it in compliance with such request, order or direction. If an Event of Default specified in Section 6.01(8) or 6.01(9) occurs, all unpaid principal, premium, if any, and accrued interest on the Securities then outstanding shall IPSO FACTO become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholder. Upon payment of such principal amount and interest, all of the Company's obligations under the Securities and this Indenture, other than obligations under Section 7.07, shall terminate. The Holders of a majority in principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (i) all existing Events of Default, other than the non-payment of the principal and interest on the Securities which have become due solely by such declaration of acceleration, have been cured or waived, (ii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid, and (iii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. No such rescission shall affect any subsequent default or impair any right consequent thereto. In the event that a declaration of acceleration under either Section 6.01(4) or 6.01(5) above has occurred and is continuing, such declaration of acceleration shall be automatically annulled if the Indebtedness that is the subject of such Event of Default has been discharged or paid or the holders of such Indebtedness shall have rescinded their declaration of acceleration in respect of such Indebtedness within 60 days thereafter and no other Event of Default has occurred during such 60-day period which has not been cured or waived. SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. -70- The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. SECTION 6.04. Waiver of Past Defaults. Subject to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except a Default in the payment of principal of, premium, if any, or interest on any Security as specified in clauses (1) and (2) of Section 6.01 or in respect of any provision hereof which cannot be modified or amended without the consent of the Holder so affected pursuant to Section 9.02. When a Default or Event of Default is so waived, it shall be deemed cured and cease to exist. SECTION 6.05. Control by Majority. The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it including, without limitation, any remedies provided for in Section 6.03. Subject to Section 7.01, however, the Trustee may refuse to follow any direction that conflicts with any law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Securityholder, or that may involve the Trustee in personal liability; PROVIDED that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. SECTION 6.06. Limitation on Suits. A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless: (1) the Holder gives to the Trustee notice of a continuing Event of Default; (2) Holders of at least 25% in principal amount of the outstanding Securities make a written request to the Trustee to pursue the remedy; -71- (3) such Holders offer to the Trustee reasonable indemnity against any loss, liability or expense to be incurred in compliance with such request; (4) the Trustee does not comply with the request within 30 days after receipt of the request and the offer of satisfactory indemnity; and (5) during such 30-day period the Holders of a majority in principal amount of the outstanding Securities do not give the Trustee a direction which, in the opinion of the Trustee, is inconsistent with the request. A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over such other Securityholder. SECTION 6.07. Rights of Holders To Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on a Security, on or after the respective due dates expressed in such Security, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. SECTION 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal or interest specified in clause (1) or (2) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company, the Guarantors or any other obligor on the Securities for the whole amount of principal and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per annum borne by the Securities and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, taxes, disbursements and advances of the Trustee, its agents and counsel) and the Securi- -72- tyholders allowed in any judicial proceedings relating to the Company, the Guarantors or any other obligor upon the Securities, any of their respective creditors or any of their respective property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings is hereby authorized by each Securityholder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Securityholders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, taxes, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee under Section 7.07. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Securityholder in any such proceeding. SECTION 6.10. Priorities. If the Trustee collects any money pursuant to this Article Six, it shall pay out the money in the following order: First: to the Trustee for amounts due under Section 7.07; Second: to Holders for interest accrued on the Securities, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for interest; Third: to Holders for principal amounts owing under the Securities and other amounts owing to the Holders with respect to the Securities, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and other amounts owing to the Holders with respect to the Securities; and Fourth: to the Company or any other obligor on the Securities, as their interests may appear, or as a court of competent jurisdiction may direct. The Trustee, upon prior notice to the Company, may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. -73- SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Securities. SECTION 6.12. Ranking. Every Holder, by accepting a Security, shall be deemed to agree that the indebtedness of Doe Run Peru evidenced by its Guarantee will be contractually subordinated to the indebtedness under the Peruvian Revolving Credit Facility. The Trustee is authorized to take any and all actions and execute any necessary documentation, whether on the Issue Note or at any time thereafter, to effectuate the foregoing subordination. In addition, except as described in the preceding sentence, the indebtedness of Doe Run Mining and Doe Run Peru evidenced by their Guarantee will rank senior in right of payment to all future unsecured indebtedness of Doe Run Mining and Doe Run Peru, respectively, subject to statutorily preferred exceptions and statutorily mandated priorities based on the date of issuance with respect to payment of obligations under applicable Peruvian law. ARTICLE SEVEN TRUSTEE The Trustee hereby accepts the trust imposed upon it by this Indenture and covenants and agrees to perform the same, as herein expressed. SECTION 7.01. Duties of Trustee. (a) If a Default or an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise thereof as a pru- -74- dent person would exercise or use under the circumstances in the conduct of his own affairs. (b) Except during the continuance of a Default or an Event of Default: (1) The Trustee need perform only those duties as are specifically set forth in this Indenture and no covenants or obligations shall be implied in this Indenture that are adverse to the Trustee. (2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. (c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (1) This paragraph does not limit the effect of paragraph (b) of this Section 7.01. (2) The Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts. (3) The Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Sections 6.02 or 6.05. (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. (e) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section 7.01. -75- (f) The Trustee shall not be liable for interest on any money or assets received by it except as the Trustee may agree with the Company. Assets held in trust by the Trustee need not be segregated from other assets except to the extent required by law. SECTION 7.02. Rights of Trustee. Subject to Section 7.01: (a) The Trustee may rely and shall be fully protected in acting or refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. (b) Before the Trustee acts or refrains from acting, it may consult with counsel and may require an Officers' Certificate or an Opinion of Counsel, which shall conform to Sections 10.04 and 10.05. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion. (c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action that it takes or omits to take in good faith which it believes to be authorized or within its rights or powers. (e) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, notice, request, direction, consent, order, bond, debenture, or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled, upon reasonable notice to the Company, to examine the books, records, and premises of the Company, personally or by agent or attorney. (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses -76- and liabilities which may be incurred by it in compliance with such request, order or direction. SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company, any Subsidiary of the Company or their respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. SECTION 7.04. Trustee's Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company's use of the proceeds from the Securities, and it shall not be responsible for any statement in the Securities other than the Trustee's certificate of authentication. SECTION 7.05. Notice of Default. If a Default or an Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Securityholder, as their names and addresses appear on the Securityholder list described in Section 2.05, notice of the uncured Default or Event of Default within 90 days after the Trustee obtains actual knowledge that such Default or Event of Default has occurred. Except in the case of a Default or an Event of Default in payment of principal of, or interest on, any Security, and a Default that resulted from the failure to comply with Sections 4.15, 4.16 or 5.01, the Trustee may withhold the notice if and so long as its board of directors, the executive committee of its board of directors or a committee of its directors and/or Trust Officers in good faith determines that withholding the notice is in the interest of the Securityholders. SECTION 7.06. Reports by Trustee to Holders. This Section 7.06 shall not be operative as a part of this Indenture until this Indenture is qualified under the TIA, and, until such qualification, this Indenture shall be construed as if this Section 7.06 were not contained herein. Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall, to the extent that any of the events described in TIA ss. 313(a) occurred within the previous twelve months, but not otherwise, -77- mail to each Securityholder a brief report dated as of such May 15 that complies with TIA ss. 313(a). The Trustee also shall comply with TIA ss.ss. 313(b) and 313(c). A copy of each report at the time of its mailing to Securityholders shall be mailed to the Company and filed with the SEC and each stock exchange, if any, on which the Securities are listed. The Company shall notify the Trustee if the Securities become listed on any securities exchange. SECTION 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time reasonable compensation for its services as the Company and the Trustee may agree. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all tax obligations imposed on the Trustee related to this Indenture and all reasonable out-of-pocket expenses incurred or made by it. Such expenses shall include the reasonable fees and expenses of the Trustee's agents and counsel. The Company shall indemnify the Trustee and its agents for, and hold them harmless against, any loss, liability or expense incurred by them except for such actions to the extent caused by any negligence or bad faith on their part, arising out of or in connection with the administration of this trust including the reasonable costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of their rights, powers or duties hereunder. The Trustee shall notify the Company promptly of any claim asserted against the Trustee for which it may seek indemnity, but the Trustee's failure to so notify the Company shall not affect the Company's obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel; provided that the Company will not be required to pay such fees and expenses if it assumes the Trustee's defense and there is no conflict of interest between the Company and the Trustee in connection with such defense as reasonably determined by the Trustee. The Company need not pay for any settlement made without its written consent. The Company need not reimburse any expense or indemnify against any loss or liability to the extent incurred by the Trustee through its negligence, bad faith or willful misconduct. -78- To secure the Company's payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Securities on all assets or money held or collected by the Trustee, in its capacity as Trustee, except assets or money held in trust to pay principal of or interest on particular Securities. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) occurs, such expenses and the compensation for such services are intended to constitute expenses of administration under any Bankruptcy Law. SECTION 7.08. Replacement of Trustee. The Trustee may resign by so notifying the Company. The Holders of a majority in principal amount of the outstanding Securities may remove the Trustee by so notifying the Company and the Trustee and may appoint a successor trustee with the Company's consent. The Company may remove the Trustee if: (1) the Trustee fails to comply with Section 7.10; (2) the Trustee is adjudged bankrupt or insolvent; (3) a receiver or other public officer takes charge of the Trustee or its property; or (4) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall notify each Holder of such event and shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided in Section 7.07, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Securityholder. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the re- -79- tiring Trustee, the Company or the Holders of at least 10% in principal amount of the outstanding Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company's obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. SECTION 7.09. Successor Trustee by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible hereunder, be the successor Trustee. SECTION 7.10. Eligibility; Disqualification. This Indenture shall always have a Trustee who satisfies the requirement of TIA ss.ss. 310(a)(1) and 310(a)(5). The Trustee (or in the case of a corporation included in a bank holding company system, the related bank holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. In addition, if the Trustee is a corporation included in a bank holding company system, the Trustee, independently of such bank holding company, shall meet the capital requirements of TIA ss. 310(a)(2). The Trustee shall comply with TIA ss. 310(b); PROVIDED, HOWEVER, that there shall be excluded from the operation of TIA ss. 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Company or the Guarantors are outstanding, if the requirements for such exclusion set forth in TIA ss. 310(b)(1) are met. SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA ss. 311(a), excluding any creditor relationship listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be subject to TIA ss. 311(a) to the extent indicated therein. -80- ARTICLE EIGHT DISCHARGE OF INDENTURE; DEFEASANCE SECTION 8.01. Termination of Company's Obligations. The Company and the Guarantors may terminate their obligations under the Securities and the Guarantees and this Indenture, except those obligations referred to in the penultimate paragraph of this Section 8.01, if all Securities previously authenticated and delivered (other than destroyed, lost or stolen Securities which have been replaced or paid and Securities for whose payment money has heretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation and the Company has paid all sums payable by it hereunder, or if: (a) pursuant to Article Three, the Company shall have given notice to the Trustee and mailed a notice of redemption to each Holder of the redemption of all of the Securities under arrangements satisfactory to the Trustee for the giving of such notice; (b) the Company shall have irrevocably deposited or caused to be deposited with the Trustee or a trustee satisfactory to the Trustee, under the terms of an irrevocable trust agreement in form and substance satisfactory to the Trustee, as trust funds in trust solely for the benefit of the Holders for that purpose, money or direct non-callable obligations of, or non-callable obligations guaranteed by, the United States of America for the payment of which guarantee or obligation the full faith and credit of the United States is pledged ("U.S. Government Obligations") maturing as to principal and interest in such amounts and at such times as are sufficient without consideration of any reinvestment of such interest, to pay principal of, premium, if any, and interest on such outstanding Securities to redemption as certified to the Trustee by a nationally recognized firm of independent public accountants designated by the Company; PROVIDED that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such U.S. Government Obligations to the payment of said principal, premium, if any, and interest with respect to the Securities; and (c) the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent providing for the -81- termination of the Company's obligation under the Securities, the Guarantees and this Indenture have been complied with. Notwithstanding the foregoing paragraph, the Company's obligations in Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02, 7.07, 7.08, 8.04 and 8.05 shall survive until the Securities are no longer outstanding. After the Securities are no longer outstanding, the Company's obligations in Sections 7.07, 8.04 and 8.05 shall survive. After such delivery or irrevocable deposit the Trustee upon request shall acknowledge in writing the discharge of the Company's obligations under the Securities, the Guarantees and this Indenture except for those surviving obligations specified above. SECTION 8.02. Legal Defeasance and Covenant Defeasance. (a) The Company may, at its option by Board Resolution, at any time, with respect to the Securities, elect to have either paragraph (b) or paragraph (c) below be applied to the outstanding Securities upon compliance with the conditions set forth in paragraph (d). (b) Upon the Company's exercise under paragraph (a) of the option applicable to this paragraph (b), the Company shall be deemed to have been released and discharged from its obligations with respect to the outstanding Securities and the Guarantees on the date the conditions set forth below are satisfied (hereinafter, "legal defeasance"). For this purpose, such legal defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding Securities, which shall thereafter be deemed to be "outstanding" only for the purposes of paragraph (e) below and the other Sections of and matters under this Indenture referred to in (i) and (ii) below, and to have satisfied all its other obligations under such Securities and Guarantees and this Indenture insofar as such Securities and Guarantees are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Securities to receive solely from the trust fund described in paragraph (d) below and as more fully set forth in such paragraph, payments in respect of the principal of and interest on such Securities and Guarantees when such payments are due, (ii) the Company's obligations with respect to such Securities and Guarantees under Sections 2.05, 2.06, 2.07, 2.08, 4.02, 7.07, 7.08, 8.04 and 8.05, (iii) the rights, powers, trusts, -82- duties and immunities of the Trustee hereunder and (iv) this Section 8.02. Subject to compliance with this Section 8.02, the Company may exercise its option under this paragraph (b) notwithstanding the prior exercise of its option under paragraph (c) below with respect to the Securities. (c) Upon the Company's exercise under paragraph (a) of the option applicable to this paragraph (c), the Company shall be released and discharged from its obligations under any covenant contained in Article Five and in Sections 4.03, 4.07, 4.09 and 4.11 through 4.21 with respect to the outstanding Securities on and after the date the conditions set forth below are satisfied (hereinafter, "covenant defeasance"), and the Securities shall thereafter be deemed to be not "outstanding" for the purpose of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the outstanding Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. (d) The following shall be the conditions to application of either paragraph (b) or paragraph (c) above to the outstanding Securities: (i) the Company shall irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal of and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge principal of, premium, if any, and interest on the out- -83- standing Securities on the Maturity Date of such principal or installment of principal or interest in accordance with the terms of this Indenture and of such Securities; PROVIDED, HOWEVER, that the Trustee (or other qualifying trustee) shall have received an irrevocable written order from the Company instructing the Trustee (or other qualifying trustee) to apply such money or the proceeds of such U.S. Government Obligations to said payments with respect to the Securities; (ii) no Default or Event of Default or event which with notice or lapse of time or both would become a Default or an Event of Default with respect to the Securities shall have occurred and be continuing on the date of such deposit or, insofar as Sections 6.01(8) and (9) are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period); (iii) such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a Default or Event of Default under, this Indenture or any other agreement or instrument to which the Company is a party or by which it is bound; (iv) in the case of an election under paragraph (b) above, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (x) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (y) since the date of this Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such legal defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred; (v) in the case of an election under paragraph (c) above, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; -84- (vi) in the case of an election under either paragraph (b) or (c) above, an Opinion of Counsel to the effect that, assuming no intervening bankruptcy of the Company between the date of deposit and the 91st day following the date of deposit and that no Holder is an insider of the Company, (x) the trust funds will not be subject to any rights of any other holders of Indebtedness of the Company, and (y) after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable Bankruptcy Law; PROVIDED, HOWEVER, that if a court were to rule under any such law in any case or proceeding that the trust funds remained property of the Company, no opinion needs to be given as to the effect of such laws on the trust funds except the following: (A) assuming such trust funds remained in the Trustee's possession prior to such court ruling to the extent not paid to Holders of Securities, the Trustee will hold, for the benefit of the Holders of Securities, a valid and enforceable security interest in such trust funds that is not avoidable in bankruptcy or otherwise, subject only to principles of equitable subordination, (B) the Holders of Securities will be entitled to receive adequate protection of their interests in such trust funds if such trust funds are used, and (C) no property, rights in property or other interests granted to the Trustee or the Holders of Securities in exchange for or with respect to any of such funds will be subject to any prior rights of any other Person, subject only to prior Liens granted under Section 364 of Title 11 of the U.S. Bankruptcy Code (or any section of any other Bankruptcy Law having the same effect), but still subject to the foregoing clause (B); and (vii) the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that (A) all conditions precedent provided for relating to either the legal defeasance under paragraph (b) above or the covenant defeasance under paragraph (c) above, as the case may be, have been complied with and (B) if any other Indebtedness of the Company shall then be outstanding, such legal defeasance or covenant defeasance will not violate the provisions of the agreements or instruments evidencing such Indebtedness. Notwithstanding the foregoing, the Opinion of Counsel and a ruling from the Internal Revenue Service required by clause (iv) above of this Section 8.02 need not be delivered if all Securities not theretofore delivered to the Trustee for cancellation (i) have become due and payable, (ii) will become due and payable on the Maturity Date within one year or (iii) are to be called for redemption within one year under arrange- -85- ments satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. (e) All money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this paragraph (e), the "Trustee") pursuant to paragraph (d) above in respect of the outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (other than the Company or any of its Affiliates) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal and interest, but such money need not be segregated from other funds except to the extent required by law. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to paragraph (d) above or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Securities. Anything in this Section 8.02 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request, in writing, by the Company any money or U.S. Government Obligations held by it as provided in paragraph (d) above which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent legal defeasance or covenant defeasance. SECTION 8.03. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Sections 8.01 and 8.02, and shall apply the deposited money and the money from U.S. Government Obligations in accordance with this Indenture to the payment of principal of, premium, if any, and interest on the Securities. SECTION 8.04. Repayment to Company. Subject to Sections 7.07, 8.01 and 8.02, the Trustee shall promptly pay to the Company, upon receipt by the Trustee -86- of an Officers' Certificate, any excess money, determined in accordance with Sections 8.02(d)(i) and (e), held by it at any time. The Trustee and the Paying Agent shall pay to the Company upon receipt by the Trustee or the Paying Agent, as the case may be, of an Officers' Certificate, any money held by it for the payment of principal or interest that remains unclaimed for two years; PROVIDED, HOWEVER, that the Trustee and the Paying Agent before being required to make any payment may, but need not, at the expense of the Company, cause to be published once in a newspaper of general circulation in The City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Securityholders entitled to money must look solely to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee or Paying Agent with respect to such money shall thereupon cease. SECTION 8.05. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Indenture by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then and only then the Company's obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had been made pursuant to this Indenture until such time as the Trustee is permitted to apply all such money or U.S. Government Obligations in accordance with this Indenture; PROVIDED, HOWEVER, that if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent. ARTICLE NINE AMENDMENTS, SUPPLEMENTS AND WAIVERS SECTION 9.01. Without Consent of Holders. From time to time, the Company and the Guarantors when authorized by Board Resolutions, and the Trustee, to- -87- gether, may amend or supplement this Indenture or the Securities without notice to or consent of any Securityholder: (1) to cure any ambiguity, defect or inconsistency; provided that such amendment or supplement does not adversely affect the rights of any Holder; (2) to comply with Article Five; (3) to provide for uncertificated Securities in addition to or in place of certificated Securities; (4) to make any other change that does not materially adversely affect the rights of any Securityholders hereunder, including, without limitation, adding Restricted Subsidiaries as additional Guarantors; or (5) to comply with any requirements of the SEC in connection with the qualification of this Indenture under the TIA; PROVIDED that the Company has delivered to the Trustee an Opinion of Counsel and an Officers' Certificate, each stating that such amendment or supplement complies with the provisions of this Section 9.01. SECTION 9.02. With Consent of Holders. Subject to Section 6.07, the Company and the Guarantors, when authorized by Board Resolutions, and the Trustee, together, with the written consent of the Holder or Holders of at least a majority in aggregate principal amount of the outstanding Securities, may amend or supplement this Indenture or the Securities, without notice to any other Securityholders. Subject to Section 6.07, the Holder or Holders of a majority in aggregate principal amount of the outstanding Securities may waive compliance by the Company with any provision of this Indenture or the Securities without notice to any other Securityholder. However, without the consent of each Securityholder, no amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may: (1) reduce the principal amount of Securities whose Holders must consent to an amendment, supplement or waiver of any provision of this Indenture or the Securities; (2) reduce the rate of, or extend the time for payment of, interest, including defaulted interest, on any Security; -88- (3) reduce the principal amount of any Security or any premium thereon; (4) change the Maturity Date of any Security, or alter the redemption provisions or the repurchase provisions in this Indenture or the Securities in a manner adverse to any Holder; (5) waive a default in the payment of the principal of, interest on, or redemption payment or repurchase payment required hereunder with respect to, any Security, including without limitation, a failure to make payment when required upon a Change of Control or after an Asset Sale; (6) make any changes in any provisions relating to waivers of defaults, the ability of the Holders to enforce their rights under this Indenture, the Securities or this Section 9.02; (7) make the principal of, or the interest on any Security payable in money other than as provided for in this Indenture and the Securities as in effect on the date hereof; (8) affect the ranking of the Securities or the Guarantees in a manner adverse to the Holders; (9) after the Company's obligation to purchase the Securities arises thereunder, amend, change or modify in any material respect any obligation of the Company to make and consummate a Change of Control Offer in the event of a Change of Control or make and consummate an Asset Sale Offer in the event of an Asset Sale or waive any default in the performance thereof or modify any of the provisions or definitions with respect to such offers; or (10) release the Guarantee of any Significant Subsidiary. It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any -89- way impair or affect the validity of any such supplemental indenture. SECTION 9.03. Compliance with TIA. From the date on which this Indenture is qualified under the TIA, every amendment, waiver or supplement of this Indenture or the Securities shall comply with the TIA as then in effect. SECTION 9.04. Revocation and Effect of Consents. Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his Security or portion of his Security by notice to the Trustee or the Company received before the date on which the Trustee receives an Officers' Certificate certifying that the Holders of the requisite principal amount of Securities have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. Notwithstanding the above, nothing in this paragraph shall impair the right of any Securityholder under ss. 316(b) of the TIA. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those persons who were Holders at such record date (or their duly designated proxies), and only those persons, shall be entitled to revoke any consent previously given, whether or not such persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. After an amendment, supplement or waiver becomes effective, it shall bind every Securityholder, unless it makes a change described in any of clauses (1) through (10) of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security. -90- SECTION 9.05. Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security (and the Guarantors shall execute the Guarantees thereon) that reflects the changed terms. Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement or waiver. SECTION 9.06. Trustee To Sign Amendments, Etc. The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article Nine; PROVIDED that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee's own rights, duties or immunities under this Indenture. The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers' Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this Indenture.

The Paying Agent or Registrar may make reasonable rules for its functions. SECTION 10.07. Legal Holidays. A "Legal Holiday" used with respect to a particular place of payment is a Saturday, a Sunday or a day on which banking institutions in New York, New York or at such place of payment are not required to be open.

SECTION 10.08. Governing Law. THIS INDENTURE, THE SECURITIES AND THE GUARANTEES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS.

Any such indenture, loan or debt agreement may not be used to interpret this Indenture. SECTION 10.10. No Recourse Against Others.

Each Securityholder by accepting a Security waives and releases all such liability. Such waiver and re- -94- lease are part of the consideration for the issuance of the Securities. SECTION 10.11. Successors. All agreements of the Company and the Guarantors in this Indenture and the Securities shall bind its successors. All agreements of the Trustee in this Indenture shall bind its successor. SECTION 10.12. Duplicate Originals. All parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together shall represent the same agreement. SECTION 10.13. Severability. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, in any respect for any reason, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. ARTICLE ELEVEN GUARANTEE OF SECURITIES SECTION 11.01. Unconditional Guarantee. Subject to the provisions of this Article Eleven, each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably guarantees, on a senior basis, except as described in Section 6.12, (such guarantee to be referred to herein as a "Guarantee") to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Securities or the obligations of the Company or any other Guarantors to the Holders or the Trustee hereunder or thereunder, that: (a) the principal of, premium, if any, and interest on the Securities shall be duly and punctually paid in full when due, whether at maturity, upon redemption at the option of Holders pursuant to the provisions of the Securities relating thereto, by acceleration or otherwise, and interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Securities and all other obligations of the Company or the Guarantors to the Holders or the Trustee hereunder or thereunder (including amounts due the -95- Trustee under Section 7.07 hereof) and all other obligations shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Securities or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, or failing performance of any other obligation of the Company to the Holders under this Indenture or under the Securities, for whatever reason, each Guarantor shall be obligated to pay, or to perform or cause the performance of, the same immediately. An Event of Default under this Indenture or the Securities shall constitute an event of default under this Guarantee, and shall entitle the Holders of Securities to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the obligations of the Company. Each of the Guarantors hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Securities with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same, whether or not a Guarantee is affixed to any particular Security, or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each of the Guarantors hereby waives the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Guarantee shall not be discharged except by complete performance of the obligations contained in the Securities, this Indenture and this Guarantee. This Guarantee is a guarantee of payment and not of collection. If any Holder or the Trustee is required by any court or otherwise to return to the Company or to any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or such Guarantor, any amount paid by the Company or such Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between it, on the one hand, and the Holders of Securities and the Trustee, on the other hand, (a) subject to this Article Eleven, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six hereof for the purposes of this Guarantee, notwithstanding any stay, in- -96- junction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (b) in the event of any acceleration of such obligations as provided in Article Six hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Guarantee. No stockholder, officer, director, employee or incorporator, past, present or future, or any Guarantor, as such, shall have any personal liability under this Guarantee by reason of his, her or its status as such stockholder, officer, director, employee or incorporator. Each Guarantor that makes a payment or distribution under its Guarantee shall be entitled to a contribution from each other Guarantor in an amount pro rata based on the net assets of each Guarantor, determined in accordance with GAAP. SECTION 11.02. Limitations on Guarantees. The obligations of each Guarantor under its Guarantee are limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under this Indenture, will result in the obligations of such Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under any laws of the United States, any state of the United States, the District of Columbia, the Republic of Peru or the Cayman Islands or any political subdivisions or territories therein or any other jurisdiction under which a Guarantor is organized. SECTION 11.03. Execution and Delivery of Guarantee. To further evidence the Guarantee set forth in Section 11.01, each Guarantor hereby agrees that a notation of such Guarantee, substantially in the form of Exhibit M herein, shall be endorsed on each Security authenticated and delivered by the Trustee. Such Guarantee shall be executed on behalf of each Guarantor by either manual or facsimile signature of two Officers of each Guarantor, each of whom, in each case, shall have been duly authorized to so execute by all requisite corporate action. The validity and enforceability of any Guarantee shall not be affected by the fact that it is not affixed to any particular Security. -97- Each of the Guarantors hereby agrees that its Guarantee set forth in Section 11.01 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Guarantee. If an Officer of a Guarantor whose signature is on this Indenture or a Guarantee no longer holds that office at the time the Trustee authenticates the Security on which such Guarantee is endorsed or at any time thereafter, such Guarantor's Guarantee of such Security shall be valid nevertheless. The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of each Guarantor. SECTION 11.04. Release of a Guarantor. (a) If no Default exists or would exist under this Indenture, upon the sale or disposition of all of the Capital Stock of a Guarantor by the Company, in a transaction constituting an Asset Sale the Net Cash Proceeds of which are applied in accordance with Section 4.16, or upon the consolidation or merger of a Guarantor with or into any Person in compliance with Article Five (in each case, other than to the Company or an Affiliate of the Company), or if any Guarantor is dissolved or liquidated in accordance with this Indenture, such Guarantor's Guarantee shall be released, and such Guarantor and each Subsidiary of such Guarantor that is also a Guarantor shall be deemed released from all obligations under this Article Eleven without any further action required on the part of the Trustee or any Holder. Any Guarantor not so released or the entity surviving such Guarantor, as applicable, shall remain or be liable under its Guarantee as provided in this Article Eleven. (b) The Trustee shall deliver an appropriate instrument evidencing the release of a Guarantor upon receipt of a request by the Company or such Guarantor accompanied by an Officers' Certificate and an Opinion of Counsel certifying as to the compliance with this Section 11.04, provided the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers Certificates of the Company. The Trustee shall execute any documents reasonably requested by the Company or a Guarantor in order to evidence the release of such Guarantor from its obligations under its Guarantee endorsed on the Securities and under this Article Eleven. -98- Except as set forth in Articles Four and Five and this Section 11.04, nothing contained in this Indenture or in any of the Securities shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor. SECTION 11.05. Waiver of Subrogation. Until this Indenture is discharged and all of the Securities are discharged and paid in full, each Guarantor hereby irrevocably waives and agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of the Company's obligations under the Securities or this Indenture and such Guarantor's obligations under this Guarantee and this Indenture, in any such instance including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the Holders against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and any amounts owing to the Trustee or the Holders of Securities under the Securities, this Indenture, or any other document or instrument delivered under or in connection with such agreements or instruments, shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Trustee or the Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 11.05 is knowingly made in contemplation of such benefits. SECTION 11.06. Immediate Payment. Each Guarantor agrees to make immediate payment to the Trustee on behalf of the Holders of all Obligations owing or payable to the respective Holders upon receipt of a demand -99- for payment therefor by the Trustee to such Guarantor in writing. SECTION 11.07. No Set-Off. Each payment to be made by a Guarantor hereunder in respect of the Obligations shall be payable in the currency or currencies in which such Obligations are denominated, and shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. SECTION 11.08. Obligations Continuing. The obligations of each Guarantor hereunder shall be continuing and shall remain in full force and effect until all the obligations have been paid and satisfied in full. Each Guarantor agrees with the Trustee that it will from time to time deliver to the Trustee suitable acknowledgments of this continued liability hereunder. SECTION 11.09. Obligations Reinstated. The obligations of each Guarantor hereunder shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment which would otherwise have reduced the obligations of any Guarantor hereunder (whether such payment shall have been made by or on behalf of the Company or by or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Company or any Guarantor or otherwise, all as though such payment had not been made. If demand for, or acceleration of the time for, payment by the Company is stayed upon the insolvency, bankruptcy, liquidation or reorganization of the Company, all such Indebtedness otherwise subject to demand for payment or acceleration shall nonetheless be payable by each Guarantor as provided herein. SECTION 11.10. Obligations Not Affected. The obligations of each Guarantor hereunder shall not be affected, impaired or diminished in any way by any act, omission, matter or thing whatsoever, occurring before, upon or after any demand for payment hereunder (and whether or not known or consented to by any Guarantor or any of the Holders) which, but for this provision, might constitute a whole or partial defense to a claim against any Guarantor hereunder or might operate to release or otherwise exonerate any Guarantor from any of its obligations hereunder or otherwise affect such -100- obligations, whether occasioned by default of any of the Holders or otherwise. SECTION 11.11. Waiver. Without in any way limiting the provisions of Section 11.01 hereof, each Guarantor hereby waives notice or proof of reliance by the Holders upon the obligations of any Guarantor hereunder, and diligence, presentment, demand for payment on the Company, protest or notice of dishonor of any of the Obligations, or other notice or formalities to the Company of any kind whatsoever. SECTION 11.12. No Obligation To Take Action Against the Company. Neither the Trustee nor any other Person shall have any obligation to enforce or exhaust any rights or remedies or to take any other steps under any security for the Obligations or against the Company or any other Person or any property of the Company or any other Person before the Trustee is entitled to demand payment and performance by any or all Guarantors of their liabilities and obligations under their Guarantees or under this Indenture. SECTION 11.13. Dealing with the Company and Others. The Holders, without releasing, discharging, limiting or otherwise affecting in whole or in part the obligations and liabilities of any Guarantor hereunder and without the consent of or notice to any Guarantor, may (a) grant time, renewals, extensions, compromises, concessions, waivers, releases, discharges and other indulgences to the Company or any other Person; (b) take or abstain from taking security or collateral from the Company or from perfecting security or collateral of the Company; (c) release, discharge, compromise, realize, enforce or otherwise deal with or do any act or thing in respect of (with or without consideration) any and all collateral, mortgages or other security given by the Company or any third party with respect to the obligations or matters contemplated by this Indenture or the Securities; (d) accept compromises or arrangements from the Company; -101- (e) apply all monies at any time received from the Company or from any security upon such part of the Obligations as the Holders may see fit or change any such application in whole or in part from time to time as the Holders may see fit; and (f) otherwise deal with, or waive or modify their right to deal with, the Company and all other Persons and any security as the Holders or the Trustee may see fit. SECTION 11.14. Default and Enforcement.

If Telerate Page 3750 does not include such a rate or is unavailable on a Determination Date, LIBOR for the Interest Period shall be the arithmetic mean of the rates (expressed as a percentage per annum) for deposits in a Representative Amount (as defined) in U.S. dollars for a six-month period beginning on the second London Banking Day after the Determination Date that appears on Reuters Screen LIBO Page (as defined) as of 11:00 a.m., London time, on the Determination Date. If Reuters Screen LIBO Page does not include two or more rates or is unavailable on a Determination Date, the Calculation Agent will request the principal London office of each of four major banks in the London interbank market, as selected by the Calculation Agent, to provide such bank's offered quotation (expressed as a percentage per annum), as of approximately 11:00 a.m., London time, on such Determination Date, to prime banks in the London interbank market for deposits in a Representative Amount in U.S. dollars for a six-month period beginning on the second A-1-6 London Banking Day after the Determination Date. If at least two such offered quotations are so provided, LIBOR for the Interest Period will be the arithmetic mean of such quotations. If fewer than two such quotations are so provided, the Calculation Agent will request each of three major banks in New York City, as selected by the Calculation Agent, to provide such bank's rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on such Determination Date, for loans in a Representative Amount in U.S. dollars to leading European banks for a six-month period beginning on the second London Banking Day after the Determination Date. If at least two such rates are so provided, LIBOR for the Interest Period will be the arithmetic mean of such rates. If fewer than two such rates are so provided, then LIBOR for the Interest Period will be LIBOR in effect with respect to the immediately preceding Interest Period. "Determination Date," with respect to an Interest Period, will be the second London Banking Day preceding the first day of the Interest Period. "London Banking Day" is any day in which dealings in U.S. dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market. "Representative Amount" means a principal amount of not less than U.S. $1,000,000 for a single transaction in the relevant market at the relevant time. "Telerate Page 3750" means the display designated as "Page 3750" on the Dow Jones Telerate Service (or such other page as may replace Page 3750 on that service). "Reuters Screen LIBO Page" means the display designated as page "LIBO" on The Reuters Monitor Money Rates Service (or such other page as may replace the LIBO page on that service). The amount of interest for each day that this Security is outstanding (the "Daily Interest Amount") will be calculated by dividing the interest rate in effect for such day by 360 and multiplying the result by the principal amount of this Security. The amount of interest to be paid on this Security for each Interest Period will be calculated by adding the Daily Interest Amounts for each day in the Interest Period. All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or A-1-7 .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards). The interest rate on this Security will in no event be higher than the maximum rate permitted by New York law as the same may be modified by U.S. law of general application. Under current New York law, the maximum rate of interest is 25% per annum on a simple interest basis. This limit may not apply to Securities in which $2,500,000 or more has been invested. The Calculation Agent will, upon the request of the holder of any Floating Rate Note, provide the interest rate then in effect with respect to this Security. All calculations made by the Calculation Agent in the absence of manifest error shall be conclusive for all purposes and binding on the Company and the Holders of this Security. 2. Method of Payment. The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Record Date immediately preceding the Interest Payment Date even if the Securities are cancelled on registration of transfer or registration of exchange after such Record Date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts ("U.S. Legal Tender"). However, the Company may pay principal and interest by wire transfer of Federal funds, or interest by its check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the Paying Agent or to a Holder at the Holder's registered address. Notwithstanding the foregoing, the Company shall pay or cause to be paid all amounts payable with respect to Restricted Securities or non-DTC eligible Securities by wire transfer of Federal funds to the account of the Holders of such Securities. If this Security is a Global Security, all payments in respect of this Security will be made to the Depository or its nominee in immediately available funds in accordance with customary procedures established from time to time by the Depository. 3. Paying Agent and Registrar. Initially, STATE STREET BANK AND TRUST COMPANY (the "Trustee"), will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to the Holders. A-1-8 4. Indenture.

Securities in denominations larger than $1,000 may be redeemed in part.

The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities or portions thereof selected for redemption. No service charge shall be made for any registration of transfer or exchange or redemption of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 11.

Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Company at its request. After that, all liability of the Trustee and such Paying Agent with respect to such money shall cease. 13. Discharge Prior to Redemption or Maturity.

STATE STREET BANK AND TRUST COMPANY, as Trustee By: -------------------------------- Authorized Signatory B-1-2 THE DOE RUN RESOURCES CORPORATION Floating Interest Rate Senior Note (FIRSTS(SM)) due 2003, Series B 1. Interest. THE DOE RUN RESOURCES CORPORATION, a New York corporation (the "Company"), promises to pay interest on the principal amount of this Security at the rate per annum, reset semi-annually, equal to LIBOR (as defined below) plus 6.29%, as determined by the calculation agent (the "Calculation Agent"). Interest on this Security will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from March 12, 1998. The Company will pay interest semi-annually on each March 15 and September 15 (each, an "Interest Payment Date"), commencing September 15, 1998, for the period commencing on and including the immediately preceding Interest Payment Date and ending on and including the day next preceding the Interest Payment Date (an "Interest Period"), with the exception that the first Interest Period shall commence on and include March 12, 1998 and end on and include September 14, 1998, and at stated maturity. The Company shall pay interest on overdue principal and interest on overdue installments of interest, to the extent lawful, at a rate equal to 13.25% per annum. "LIBOR", with respect to an Interest Period, shall be the rate (expressed as a percentage per annum) for deposits in United States dollars for a six-month period beginning on the second London Banking Day (as defined) after the Determination Date (as defined) that appears on Telerate Page 3750 (as defined) as of 11:00 a.m., London time, on the Determination Date. If Telerate Page 3750 does not include such a rate or is unavailable on a Determination Date, LIBOR for the Interest Period shall be the arithmetic mean of the rates (expressed as a percentage per annum) for deposits in a Representative Amount (as defined) in U.S. dollars for a six-month period beginning on the second London Banking Day after the Determination Date that appears on Reuters Screen LIBO Page (as defined) as of 11:00 a.m., London time, on the Determination Date. If Reuters Screen LIBO Page does not include two or more rates or is unavailable on a Determination Date, the Calculation Agent will request the principal London office of each of four major banks in the London interbank market, as selected by the Calculation Agent, to provide such bank's offered quotation (expressed as a percentage per annum), as of approximately 11:00 a.m., London time, on such Determination Date, to prime banks in the London interbank market for deposits in a Representative Amount in U.S. dollars for a six-month period beginning on the second B-1-3 London Banking Day after the Determination Date. If at least two such offered quotations are so provided, LIBOR for the Interest Period will be the arithmetic mean of such quotations. If fewer than two such quotations are so provided, the Calculation Agent will request each of three major banks in New York City, as selected by the Calculation Agent, to provide such bank's rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on such Determination Date, for loans in a Representative Amount in U.S. dollars to leading European banks for a six-month period beginning on the second London Banking Day after the Determination Date. If at least two such rates are so provided, LIBOR for the Interest Period will be the arithmetic mean of such rates. If fewer than two such rates are so provided, then LIBOR for the Interest Period will be LIBOR in effect with respect to the immediately preceding Interest Period. "Determination Date," with respect to an Interest Period, will be the second London Banking Day preceding the first day of the Interest Period. "London Banking Day" is any day in which dealings in U.S. dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market. "Representative Amount" means a principal amount of not less than U.S. $1,000,000 for a single transaction in the relevant market at the relevant time. "Telerate Page 3750" means the display designated as "Page 3750" on the Dow Jones Telerate Service (or such other page as may replace Page 3750 on that service). "Reuters Screen LIBO Page" means the display designated as page "LIBO" on The Reuters Monitor Money Rates Service (or such other page as may replace the LIBO page on that service). The amount of interest for each day that this Security is outstanding (the "Daily Interest Amount") will be calculated by dividing the interest rate in effect for such day by 360 and multiplying the result by the principal amount of this Security. The amount of interest to be paid on this Security for each Interest Period will be calculated by adding the Daily Interest Amounts for each day in the Interest Period. All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or B-1-4 .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards). The interest rate on this Security will in no event be higher than the maximum rate permitted by New York law as the same may be modified by U.S. law of general application. Under current New York law, the maximum rate of interest is 25% per annum on a simple interest basis. This limit may not apply to Securities in which $2,500,000 or more has been invested. The Calculation Agent will, upon the request of the holder of any Floating Rate Note, provide the interest rate then in effect with respect to this Security. All calculations made by the Calculation Agent in the absence of manifest error shall be conclusive for all purposes and binding on the Company and the Holders of this Security. 2. Method of Payment. The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Record Date immediately preceding the Interest Payment Date even if the Securities are cancelled on registration of transfer or registration of exchange after such Record Date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts ("U.S. Legal Tender"). However, the Company may pay principal and interest by wire transfer of Federal funds, or interest by its check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the Paying Agent or to a Holder at the Holder's registered address. 3. Paying Agent and Registrar. Initially, STATE STREET BANK AND TRUST COMPANY (the "Trustee") will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to the Holders. 4. Indenture. The Company issued the Securities under an Indenture, dated as of March 12, 1998 (the "Indenture"), by and among the Company, the Guarantors and the Trustee. This Security is one of a duly authorized issue of Securities of the Company designated as its Floating Interest Rate Senior Notes (FIRSTS(SM)) due 2003, Series B (the "Series B Floating Rate Notes"), limited (except as otherwise provided in the Indenture) in aggregate B-1-5 principal amount to $55,000,000. The Securities include the Floating Rate Notes (as defined in the Indenture) and the Fixed Rate Notes (as defined in the Indenture). The Fixed Rate Notes and the Floating Rate Notes are treated as a single class of securities under the Indenture unless otherwise specified in the Indenture. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code ss.ss. 77aaa-77bbbb) (the "TIA"), as in effect on the date of the Indenture until such time as the Indenture is qualified under the TIA, and thereafter as in effect on the date on which the Indenture is qualified under the TIA. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities are referred to the Indenture and said Act for a statement of them. The Securities are general obligations of the Company limited in aggregate principal amount to $355,000,000. 5. Exchange Offer. The Series B Floating Rate Notes were issued pursuant to an exchange offer pursuant to which Floating Interest Rate Senior Notes (FIRSTS(SM)) due 2003, Series A, of the Company (the "Series A Notes"), in like principal amount and having substantially identical terms as the Series B Floating Rate Notes, were exchanged for the Series B Floating Rate Notes. The Series A Floating Rate Notes and the Series B Floating Notes are together referred to herein as the "Securities." 6. Optional Redemption. The Floating Rate Notes will be subject to redemption, in whole at any time or in part from time to time, at the option of the Company, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued interest to the redemption date, if redeemed during the twelve month period beginning on March 15 of the years indicated below: Year Percentage 1998............................................ 104.000% 1999............................................ 103.000% 2000............................................ 102.000% 2001............................................ 101.000% 2002 and thereafter............................. 100.000% 7. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each B-1-6 Holder of Securities to be redeemed at such Holder's registered address. Securities in denominations larger than $1,000 may be redeemed in part. Except as set forth in the Indenture, from and after any Redemption Date, if monies for the redemption of the Securities called for redemption shall have been deposited with the Paying Agent for redemption on such Redemption Date, then, unless the Company defaults in the payment of such Redemption Price, the Securities called for redemption will cease to bear interest and the only right of the Holders of such Securities will be to receive payment of the Redemption Price. 8. Change of Control Offer. Upon the occurrence of a Change of Control, upon the satisfaction of the conditions set forth in the Indenture, the Company shall be required to offer to purchase all of the then outstanding Securities pursuant to a Change of Control Offer at a purchase price equal to 101% of the principal amount thereof plus accrued interest, if any, to the date of purchase. Holders of Securities which are the subject of such an offer to repurchase shall receive an offer to repurchase and may elect to have such Securities repurchased in accordance with the provisions of the Indenture pursuant to and in accordance with the terms of the Indenture. 9. Limitation on Disposition of Assets. Under certain circumstances, the Company is required to apply the net proceeds from Asset Sales to repurchase Securities at a price equal to 100% of the aggregate principal amount thereof, plus accrued interest to the date of purchase. 10. Denominations; Transfer; Exchange. The Securities are in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities or portions thereof selected for redemption. No service charge shall be made for any registration of transfer or exchange or redemption of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. B-1-7 11. Persons Deemed Owners. The registered Holder of a Security shall be treated as the owner of it for all purposes. With respect to Global Securities, the Depository may grant proxies and otherwise authorize Holders of Book-Entry Securities to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder of a Security is entitled to give or take under the Indenture. 12. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Company at its request. After that, all liability of the Trustee and such Paying Agent with respect to such money shall cease. 13. Discharge Prior to Redemption or Maturity. The Company's obligations pursuant to the Indenture will be discharged, except for obligations pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Securities or upon the irrevocable deposit with the Trustee of money or U.S. Government Obligations sufficient to pay when due principal of, and premium, if any, and interest on the Securities to maturity or redemption, as the case may be. 14. Amendment; Supplement; Waiver. Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding, and any existing Default or Event of Default or compliance with any provision may be waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without notice to or consent of any Holder, the parties thereto may amend, waive or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Securities in addition to or in place of certificated Securities, comply with Article Five of the Indenture or comply with any requirements of the SEC in connection with the qualification of the Indenture under the TIA, or make any other change that does not adversely affect the rights of any Holder of a Security. B-1-8 15. Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries to, among other things, incur additional Indebtedness or Liens, make payments in respect of its Capital Stock and merge or consolidate with any other person and sell, lease, transfer or otherwise dispose of substantially all of certain of its properties or assets. The limitations are subject to a number of important qualifications and exceptions. The Company must annually report to the Trustee on compliance with such limitations. 16. Successors. When a successor assumes all the obligations of its predecessor under the Securities and the Indenture, the predecessor will be released from those obligations. 17. Defaults and Remedies. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Securities then outstanding may declare all the Securities to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Securities unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of any continuing Default or Event of Default (except a Default in payment of principal or interest) if it determines that withholding notice is in their interest. 18. Trustee Dealings with Company. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company, the Guarantors, their Subsidiaries or their respective Affiliates as if it were not the Trustee. 19. No Recourse Against Others. No stockholder, director, officer, employee or incorporator, as such, of the Company or the Guarantors shall have any liability for any obligation of the Company or the Guarantors under the Securities or the Indenture or for any claim B-1-9 based on, in respect of or by reason of, such obligations or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 20. Authentication. This Security shall not be valid until the Trustee or authenticating agent manually signs the certificate of authentication on this Security. 21. Governing Law. The Laws of the State of New York shall govern this Security and the Indenture. 22. Abbreviations and Defined Terms. Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 23. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company will cause CUSIP numbers to be printed on the Securities immediately prior to the qualification of the Indenture under the TIA as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon. 24. Guarantees. This Security will be entitled to the benefits of certain Guarantees made for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Guarantors, the Trustee and the Holders. 25.

(xi) Under current Peruvian law and regulations there is no tax, duty, levy, impost, deduction, charge or withholding (including, without limitation, any registration or transfer tax, stamp duty or similar levy) imposed or, as such counsel is aware pending or proposed, by Peru or any political subdivision thereof or taxing authority therein or any federation or organization or similar entity of which Peru is a member either (i) on or by virtue of Doe Run Mining's or Doe Run Peru's execution, delivery, performance or enforcement of this Agreement, the Loan Agreement, the Guarantees, the Indenture or any other document to be furnished hereunder or thereunder, or (ii) on any payment to be made pursuant to this Agreement, the Indenture, the Loan Agreement, the Guarantees of Doe Run Mining and Doe Run Peru or on payment to any holder of the Notes. Under current and, as such counsel is aware, proposed or pending, Peruvian law and regulations, interest payments on the Notes and the Exchange Notes are not and will not be subject to any Peruvian withholding or other tax except the 1% withholding income tax applicable to payments of interest on the loan pursuant to the Peruvian Loan Agreement. (xii) The statements made in the Final Memorandum under the headings "Business," "Enforceability of Civil Liabilities," and "The Republic of Peru" insofar as such statements purport to summarize certain provisions of Peruvian law, are fair summaries and accurate in all material respects. (xiii) Such other opinions as the Initial Purchasers or their counsel may reasonably request. References to the Final Memorandum in this subsection (e) shall include any amendment or supplement thereto prepared in accordance with the provisions of this Agreement at the Closing Date. (f) The Initial Purchasers shall have received from the Independent Accountants comfort letters dated the date hereof and the Closing Date, in form and substance satisfactory to counsel for the Initial Purchasers. -35- (g) The representations and warranties of each of the Issuers contained in this Agreement shall be true and correct on and as of the date hereof and on and as of the Closing Date as if made on and as of the Closing Date; the statements of the Issuers' officers made pursuant to any certificate delivered in accordance with the provisions hereof shall be true and correct on and as of the date made and on and as of the Closing Date; each of the Issuers shall have performed all covenants and agreements and satisfied all conditions on their part to be performed or satisfied hereunder at or prior to the Closing Date; and, except as described in the Final Memorandum (exclusive of any amendment or supplement thereto after the date hereof), subsequent to the date of the most recent financial statements in such Final Memorandum, there shall have been no event or development, and no information shall have become known, that, individually or in the aggregate, has or would be reasonably likely to have a Material Adverse Effect. (h) The sale of the Notes hereunder shall not be enjoined (temporarily or permanently) on the Closing Date. (i) Subsequent to the date of the most recent financial statements in the Final Memorandum (exclusive of any amendment or supplement thereto after the date hereof), none of the Company or any of the Subsidiaries shall have sustained any loss or interference with respect to its business or properties from fire, flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any strike, labor dispute, slow down or work stoppage or from any legal or governmental proceeding, order or decree, which loss or interference, individually or in the aggregate, has or would be reasonably likely to have a Material Adverse Effect. (j) The Initial Purchasers shall have received a certificate of each of the Issuers, dated the Closing Date, signed on behalf of the Issuers by its Chairman of the Board, Chief Executive Officer, President, any Vice President or any General Manager and the Chief Financial Officer or Finance Manager, to the effect that: (i) The representations and warranties of each of the Issuers contained in this Agreement are true and correct on and as of the date hereof and on and as of the Closing Date, and each of the Issuers has performed all covenants and agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; -36- (ii) At the Closing Date, since the date hereof or since the date of the most recent financial statements in the Final Memorandum (exclusive of any amendment or supplement thereto after the date hereof), no event or development has occurred, and no information has become known, that, individually or in the aggregate, has or would be reasonably likely to have a Material Adverse Effect; and (iii) The sale of the Notes hereunder has not been enjoined (temporarily or permanently). (k) On the Closing Date, the Initial Purchasers shall have received the Registration Rights Agreement executed by each of the Issuers and such agreement shall be in full force and effect. On or before the Closing Date, the Initial Purchasers and counsel for the Initial Purchasers shall have received such further documents, opinions, certificates, letters and schedules or instruments relating to the business, corporate, legal and financial affairs of the Company and the Subsidiaries as they shall have heretofore reasonably requested from the Company. All such documents, opinions, certificates, letters, schedules or instruments delivered pursuant to this Agreement will comply with the provisions hereof only if they are reasonably satisfactory in all material respects to the Initial Purchasers and counsel for the Initial Purchasers. The Company shall furnish to the Initial Purchasers such conformed copies of such documents, opinions, certificates, letters, schedules and instruments in such quantities as the Initial Purchasers shall reasonably request. 8. Offering of Notes; Restrictions on Transfer. (a) Each of the Initial Purchasers represents and warrants (as to itself only) that it is a qualified institutional buyer (as defined in Rule 144A) (a "QIB"). Each of the Initial Purchasers agrees with the Company (as to itself only) that (i) it has not and will not solicit offers for, or offer or sell, the Notes by any form of general solicitation or general advertising (as those terms are used in Regulation D under the Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Act; and (ii) it has and will solicit offers for the Notes only from, and will offer the Notes only to (A) in the case of offers inside the United States, persons whom the Initial Purchasers reasonably believe to be QIBs or, if any such person is buying for one or more institutional ac- -37- counts for which such person is acting as fiduciary or agent, only when such person has represented to the Initial Purchasers that each such account is a QIB, to whom notice has been given that such sale or delivery is being made in reliance on Rule 144A, and, in each case, in transactions under Rule 144A and (B) in the case of offers outside the United States, to persons other than U.S. persons ("foreign purchasers," which term shall include dealers or other professional fiduciaries in the United States acting on a discretionary basis for foreign beneficial owners (other than an estate or trust)); provided, however, that, in the case of this clause (B), in purchasing such Notes such persons are deemed to have represented and agreed as provided under the caption "Transfer Restrictions" contained in the Final Memorandum (or, if the Final Memorandum is not in existence, in the most recent Memorandum). (b) Each of the Initial Purchasers represents and warrants (as to itself only) with respect to offers and sales outside the United States that (i) it has and will comply with all applicable laws and regulations in each jurisdiction in which it acquires, offers, sells or delivers Notes or has in its possession or distributes any Memorandum or any such other material, in all cases at its own expense; (ii) the Notes have not been and will not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except in accordance with Regulation S or pursuant to an exemption from the registration requirements of the Act; (iii) it has offered the Notes and will offer and sell the Notes (A) as part of its distribution at any time and (B) otherwise until 40 days after the later of the commencement of the offering and the Closing Date, only in accordance with Rule 903 of Regulation S and, accordingly, neither it nor any persons acting on its behalf have engaged or will engage in any directed selling efforts (within the meaning of Regulation S) with respect to the Notes, and any such persons have complied and will comply with the offering restrictions requirement of Regulation S; and (iv) it agrees that, at or prior to confirmation of sales of the Notes, it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Notes from it during the restricted period a confirmation or notice to substantially the following effect: "The Securities covered hereby have not been registered under the United States Securities Act of 1933 (the "Securities Act") and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of the distribution of the Securities at any time or -38- (ii) otherwise until 40 days after the later of the commencement of the offering and the closing date of the offering, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meaning given to them in Regulation S." Terms used in this Section 8 and not defined in this Agreement have the meanings given to them in Regulation S. 9. Indemnification and Contribution. (a) Each of the Issuers, jointly and severally, agrees to indemnify and hold harmless the Initial Purchasers, and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which any Initial Purchaser or such controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of any material fact contained in any Memorandum or any amendment or supplement thereto; or (ii) the omission or alleged omission to state, in any Memorandum or any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse, as incurred, the Initial Purchasers and each such controlling person for any legal or other expenses incurred by the Initial Purchasers or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, the Issuers will not be liable in any such case to the extent that any such loss, claim, damage, or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in any Memorandum or any amendment or supplement thereto in reliance upon and in conformity with written information concerning the Initial Purchasers furnished to the Issuers by the Initial Purchasers specifically for use therein; provided, further, however, that the Issuers will not be required to provide the indemnity hereunder if such untrue statement or alleged untrue statement or omission or alleged omission was contained or made in any Memorandum and corrected in a subsequent Memorandum and any such loss, claim, -39- damage or liability suffered or incurred by an indemnified party resulted from any action, claim or suit by any purchaser of the Notes from such indemnified party and such indemnified party failed to deliver or provide a copy of such subsequent Memorandum to such person with or prior to the confirmation of the sale of such Notes to such person; provided that the Issuers will be required to provide the indemnity hereunder if any Issuer fails to comply with Section 5(d) of this Agreement with respect to such subsequent Memorandum. This indemnity agreement will be in addition to any liability that the Issuers may otherwise have to the indemnified parties. The Issuers shall not be liable under this Section 9 for any settlement of any claim or action effected without its prior written consent, which shall not be unreasonably withheld. (b) The Initial Purchasers agree to indemnify and hold harmless the Issuers, their directors, their officers and each person, if any, who controls any of the Issuers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Memorandum or any amendment or supplement thereto or any Application, or (ii) the omission or the alleged omission to state therein a material fact required to be stated in any Memorandum or any amendment or supplement thereto or any Application, or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Initial Purchaser, furnished to the Issuers by the Initial Purchasers specifically for use therein; and subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses incurred by the Issuers or any such director, officer or controlling person in connection with investigating or defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability that the Initial Purchasers may otherwise have to the indemnified parties. The Initial Purchasers shall not be liable under this Section 9 for any settlement of any claim or action effected without their consent, which shall not be unreasonably withheld. The Company shall not, without the prior written consent -40- of the Initial Purchasers, effect any settlement or compromise of any pending or threatened proceeding in respect of which any Initial Purchaser is or could have been a party, or indemnity could have been sought hereunder by any Initial Purchaser, unless such settlement (A) includes an unconditional written release of the Initial Purchasers, in form and substance reasonably satisfactory to the Initial Purchasers, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any Initial Purchaser. (c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 9, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the extent such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after receipt by the indemnifying party of notice of the institution of such action, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the -41- right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Initial Purchasers in the case of paragraph (a) of this Section 9 or the Issuers in the case of paragraph (b) of this Section 9, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions) or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnified party waived in writing its rights under this Section 9, in which case the indemnified party may effect such a settlement without such consent. (d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 9 is unavailable to, or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or -42- parties on the one hand and the indemnified party on the other from the offering of the Notes or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Issuers on the one hand and any Initial Purchaser on the other shall be deemed to be in the same proportion as the total proceeds from the offering (net of discounts and commissions but before deducting expenses) received by the Company bear to the total discounts and commissions received by such Initial Purchaser. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuers on the one hand, or such Initial Purchaser on the other, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The Issuers and the Initial Purchasers agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Initial Purchaser shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each director of the Issuers, each officer of the Issuers and each person, if any, who controls the Issuers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Issuers. 10. Survival Clause. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Issuers, their officers and the Initial Pur- -43- chasers set forth in this Agreement or made by or on behalf of them pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Issuers, any of its officers or directors, the Initial Purchasers or any controlling person referred to in Section 9 hereof and (ii) delivery of and payment for the Notes. The respective agreements, covenants, indemnities and other statements set forth in Sections 6, 9 and 15 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement. 11. Termination. (a) This Agreement may be terminated in the sole discretion of the Initial Purchasers by notice to the Issuers given prior to the Closing Date in the event that the Issuers shall have failed, refused or been unable to perform all obligations and satisfy all conditions on its part to be performed or satisfied hereunder at or prior thereto or, if at or prior to the Closing Date: (i) any of the Company or the Subsidiaries shall have sustained any loss or interference with respect to its businesses or properties from fire, flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any strike, labor dispute, slow down or work stoppage or any legal or governmental proceeding, which loss or interference, in the sole judgment of the Initial Purchasers, has had or has a Material Adverse Effect, or there shall have been, in the sole judgment of the Initial Purchasers, any event or development that, individually or in the aggregate, has or could be reasonably likely to have a Material Adverse Effect (including without limitation a change in control of the Company or the Subsidiaries), except in each case as described in the Final Memorandum (exclusive of any amendment or supplement thereto); (ii) trading in securities of any of the Issuers or in securities generally on the New York Stock Exchange, American Stock Exchange or the Nasdaq National Market shall have been suspended or minimum or maximum prices shall have been established on any such exchange or market; (iii) there shall have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations, of the Company and the Subsidiaries, taken as a whole, from that set forth in the Final Memorandum -44- (without regard to any amendment thereto after the date hereof) that is material and adverse and that makes it, in the Initial Purchasers' judgment, impracticable to market the Notes on the terms and in the manner contemplated in the Final Memorandum (without regard to any amendment thereto after the date hereof). (iv) a banking moratorium shall have been declared by New York or United States authorities or the Peruvian authorities in Peru; (v) there shall have been (A) an outbreak or escalation of hostilities between the United States or Peru and any foreign power, or (B) an outbreak or escalation of any other insurrection or armed conflict involving the United States or Peru or any other national or international calamity or emergency, or (C) any material change in the financial markets of the United States or Peru which, in the case of (A), (B) or (C) above and in the sole judgment of the Initial Purchasers, makes it impracticable or inadvisable to proceed with the offering or the delivery of the Notes as contemplated by the Final Memorandum; or (vi) any securities of any of the Issuers shall have been downgraded or placed on any "watch list" for possible downgrading by any nationally recognized statistical rating organization. (vii) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs that has a material adverse effect on the financial markets in the United States or Peru, and would, in the sole judgment of the Initial Purchasers, make it impracticable or inadvisable to market the Notes; or (viii) the enactment, publication, decree, or other promulgation of any federal or state statute, regulation, rule, order of any court or other governmental authority which, in the judgment of the Initial Purchasers, would have a Material Adverse Effect. (b) Termination of this Agreement pursuant to this Section 11 shall be without liability of any party to any other party except as provided in Section 10 hereof. 12. Information Supplied by the Initial Purchasers. The statements set forth in the last paragraph on the front -45- cover page in the third paragraph under the heading "Private Placement" in the Final Memorandum (to the extent such statements relate to the Initial Purchasers) constitute the only information furnished by the Initial Purchasers to the Issuers for the purposes of Sections 2(a) and 9 hereof. 13. Notices. All communications hereunder shall be in writing and, if sent to the Initial Purchasers, shall be mailed or delivered to (i) BT Alex. Brown Incorporated, 130 Liberty Street, New York, New York 10006, Attention: Corporate Finance Department; if sent to the Issuers, shall be mailed or delivered to the Issuers c/o The Doe Run Resources Corporation, 1801 Park 270 Drive, St. Louis, Missouri 63146, Attention: Chief Executive Officer; with a copy to Cadwalader, Wickersham & Taft, 100 Maiden Lane, New York, N.Y. 10038, Attention: Michael C.

Consent to Jurisdiction. Each of the parties hereto irrevocably agrees that any legal dispute, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby by the Initial Purchasers, directors, officers, employees or agents of the Initial Purchasers or by each person, if any, who controls the Initial Purchasers, may be instituted in any New York State or U.S. Federal court sitting in the Borough of Manhattan, New York City, New York, U.S.A. (each a "New York Court" and collectively, the "New York Courts"), and irrevocably waives, to the extent permitted by applicable law, any objection which it may now or hereafter have to the laying of venue to any such proceeding and irrevocably submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. 15. Waiver of Jury Trial; Waiver of Immunity. (a) Each of the parties to this Agreement hereby irrevocably waives all right to a trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) arising out of or relating to this Agreement or the transactions contemplated hereby. (b) To the extent that the Issuers or any of their revenues, assets or properties shall be entitled, with respect to any proceeding at any time brought against the Issuers or any -46- of their revenues, assets or properties or with respect to any suit, action or proceeding at any time brought for the purpose of enforcing or executing any judgment in any jurisdiction in which any specified court or other court is located, to any immunity from suit, from the jurisdiction of any such court, from attachment prior to judgment, from attachment in aid of execution of judgment, from execution of a judgment or from any other legal or judicial process or remedy, and to the extent of such immunity, the Issuers irrevocably agree not to claim and irrevocably waive such immunity to the fullest extent permitted by the laws of such jurisdiction (including, without limitation, the Foreign Sovereign Immunities Act of 1976 of the United States). 16. Payments. All payments hereunder shall be made without defense, setoff or counterclaim of any kind and shall be made freely available in U.S. dollars in New York without any deduction on account of taxes. If any amount is required to be withheld on account of taxes, then the Company shall pay to the Initial Purchasers such additional amounts as shall be required to be paid so that the net amount received by the Initial Purchasers, after all such deductions or withholdings, shall not be less than the Initial Purchasers would have received had no such deductions or withholdings been made or required and shall promptly deliver to the Initial Purchasers all relevant tax receipts. 17. Currency Indemnity. The obligation of the Company in respect of any sum due to the Initial Purchasers shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by the Initial Purchasers of any sum adjudged to be so due in such other currency, on which (and only to the extent that) the Initial Purchasers may in accordance with normal banking procedures purchase United States dollars with such other currency; if the United States dollars so purchased are less than the sum originally due to the Initial Purchasers hereunder, the Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Initial Purchasers against such loss. If the United States dollars so purchased are greater than the sum originally due to the Initial Purchasers hereunder, the Initial Purchasers agree to pay to the Company an amount equal the excess of the dollars so purchased over the sum originally due to the Initial Purchasers hereunder. 18. Successors. This Agreement shall inure to the benefit of and be binding upon the Initial Purchasers, the Company and their respective successors and legal representatives, and nothing expressed or mentioned in this Agreement is in- -47- tended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained; this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of such persons and for the benefit of no other person except that (i) the indemnities of the Issuers contained in Section 9 of this Agreement shall also be for the benefit of any person or persons who control the Initial Purchasers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and (ii) the indemnities of the Initial Purchasers contained in Section 9 of this Agreement shall also be for the benefit of the directors of the Issuers, their officers and any person or persons who control the Issuers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act. No purchaser of Notes from the Initial Purchasers will be deemed a successor because of such purchase. 19. APPLICABLE LAW.

Exchange Offer (a) To the extent not prohibited by applicable law or applicable interpretation of the staff of the Division of Corporation Finance of the SEC, the Company and the Guarantors shall file with the SEC, no later than the Filing Date, a Registration Statement (the "Exchange Offer Registration Statement") on an appropriate registration form with respect to a registered offer (the "Exchange Offer") to exchange any and all of the Registrable Notes for a like aggregate principal amount of notes (the "Exchange Notes") of the Company, guaranteed by the Guarantors, that are identical in all material respects to the Notes except that the Exchange Notes shall contain no restrictive legend thereon. The Exchange Offer shall comply with all applicable tender offer rules and regulations under the Exchange Act and other applicable laws. The Company and the Guarantors shall use their reasonable efforts to (x) cause the Exchange Offer Registration Statement to be declared effective under the Securities Act on or before the Effectiveness Date; (y) keep the Exchange Offer open for at least 20 business days (or longer if required by applicable law) after the date that notice of the Exchange Offer is mailed to Holders; and (z) consummate the Exchange Offer on or prior to the 180th day after the Issue Date. If, after the Exchange Offer Registra- -5- tion Statement is initially declared effective by the SEC, the Exchange Offer or the issuance of the Exchange Notes thereunder is interfered with by any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, the Exchange Offer Registration Statement shall be deemed not to have become effective for purposes of this Agreement. Each Holder that participates in the Exchange Offer will be required to represent that any Exchange Notes to be received by it will be acquired in the ordinary course of its business, that at the time of the consummation of the Exchange Offer such Holder will have no arrangement or understanding with any Person to participate in the distribution of the Exchange Notes in violation of the provisions of the Securities Act, and that such Holder is not an affiliate of the Company or the Guarantors within the meaning of the Securities Act. Upon consummation of the Exchange Offer in accordance with this Section 2, the provisions of this Agreement shall continue to apply, solely with respect to Registrable Notes that are Private Exchange Notes, Exchange Notes as to which Section 2(c)(iv) is applicable and Exchange Notes held by Participating Broker-Dealers, and the Company and the Guarantors shall have no further obligation to register Registrable Notes (other than Private Exchange Notes and other than in respect of any Exchange Notes as to which clause 2(c)(iv) hereof applies) pursuant to Section 3 hereof. No securities other than the Exchange Notes shall be included in the Exchange Offer Registration Statement. (b) The Company and the Guarantors shall include within the Prospectus contained in the Exchange Offer Registration Statement a section entitled "Plan of Distribution," reasonably acceptable to the Holders, which shall contain a summary statement of the positions taken or policies made by the staff of the SEC with respect to the potential "underwriter" status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of Exchange Notes received by such broker-dealer in the Exchange Offer (a "Participating Broker-Dealer"), whether such positions or policies have been publicly disseminated by the staff of the SEC or such positions or policies represent the prevailing views of the staff of the SEC. Such "Plan of Distribution" section shall also expressly permit, to the extent permitted by applicable policies and regulations of the SEC, the use of the Pro- -6- spectus by all Persons subject to the prospectus delivery requirements of the Securities Act, including, to the extent permitted by applicable policies and regulations of the SEC, all Participating Broker-Dealers, and include a statement describing the means by which Participating Broker-Dealers may resell the Exchange Notes in compliance with the Securities Act. The Company and Guarantors shall use their reasonable efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the Prospectus contained therein in order to permit such Prospectus to be lawfully delivered by all Persons subject to the prospectus delivery requirements of the Securities Act for such period of time as is necessary to comply with applicable law in connection with any resale of the Exchange Notes covered thereby; provided, however, that such period shall not exceed 180 days after such Exchange Offer Registration Statement is declared effective (or such longer period if extended pursuant to the last paragraph of Section 5 hereof) (the "Applicable Period"). If, prior to consummation of the Exchange Offer, the Initial Purchasers hold any Notes acquired by it that have, or that are reasonably likely to be determined to have, the status of an unsold allotment in an initial distribution, or any Holder is not entitled to participate in the Exchange Offer, the Company and the Guarantors upon the request of any such Holder shall simultaneously with the delivery of the Exchange Notes in the Exchange Offer, issue and deliver to any such Holder, in exchange (the "Private Exchange") for such Notes held by any such Holder, a like principal amount of notes (the "Private Exchange Notes") of the Company, guaranteed by the Guarantors, that are identical in all material respects to the Exchange Notes (except that they may bear a customary legend with respect to restrictions on transfer). The Private Exchange Notes shall be issued pursuant to the same indenture as the Exchange Notes and bear the same CUSIP number as the Exchange Notes. Interest on the Exchange Notes and the Private Exchange Notes will accrue from (A) the later of (i) the last interest payment date on which interest was paid on the Notes surrendered in exchange therefor or (ii) if the Notes are surrendered for exchange on a date subsequent to the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date -7- of such interest payment or (B) if no interest has been paid on the Notes, from the date of the original issuance of the Notes. In connection with the Exchange Offer, the Company and the Guarantors shall: (1) mail, or cause to be mailed, to each Holder entitled to participate in the Exchange Offer a copy of the Prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents; (2) keep the Exchange Offer open for not less than 20 business days after the date that notice of the Exchange Offer is mailed to Holders (or longer if required by applicable law); (3) utilize the services of a depositary for the Exchange Offer with an address in the Borough of Manhattan, The City of New York; (4) permit Holders to withdraw tendered Notes at any time prior to the close of business, New York time, on the last business day on which the Exchange Offer shall remain open; provided, however, that withdrawal rights may be terminated upon any extension of the Exchange Offer; and (5) otherwise comply in all material respects with all applicable laws, rules and regulations. As soon as practicable after the close of the Exchange Offer and the Private Exchange, if any, the Company and the Guarantors shall: (1) accept for exchange all Registrable Notes validly tendered and not validly withdrawn pursuant to the Exchange Offer and the Private Exchange, if any; (2) deliver to the Trustee for cancellation all Registrable Notes so accepted for exchange; and (3) cause the Trustee to authenticate and deliver promptly to each Holder of Registrable Notes, Exchange Notes or Private Exchange Notes, as the case may be, equal in principal amount to the Registrable Notes of such Holder so accepted for exchange. -8- The Exchange Offer and the Private Exchange shall not be subject to any conditions, other than that (i) the Exchange Offer or Private Exchange, as the case may be, does not violate applicable law or any applicable interpretation of the staff of the SEC, (ii) no action or proceeding shall have been instituted or threatened in any court or by any governmental agency which might materially impair the ability of the Company and the Guarantors to proceed with the Exchange Offer or the Private Exchange, and no material adverse development shall have occurred in any existing action or proceeding with respect to the Company and the Guarantors and (iii) all governmental approvals shall have been obtained, which approvals the Company and the Guarantors deem necessary for the consummation of the Exchange Offer or Private Exchange. The Exchange Notes and the Private Exchange Notes shall be issued under (i) the Indenture or (ii) an indenture identical in all material respects to the Indenture and which, in either case, has been qualified under the TIA or is exempt from such qualification and shall provide that the Exchange Notes shall not be subject to the transfer restrictions set forth in the Indenture. The Indenture or such indenture shall provide that the Exchange Notes, the Private Exchange Notes and the Notes shall vote and consent together on all matters as one class and that none of the Exchange Notes, the Private Exchange Notes or the Notes will have the right to vote or consent as a separate class on any matter. (c) If, (i) because of any change in law or in currently prevailing interpretations of the staff of the SEC, the Company and the Guarantors are not permitted to effect the Exchange Offer, (ii) the Exchange Offer is not consummated within 180 days of the Issue Date, (iii) the Initial Purchasers or any holder of Private Exchange Notes so requests in writing to the Company and the Guarantors at any time after the consummation of the Exchange Offer, or (iv) in the case of any Holder that participates in the Exchange Offer, such Holder does not receive Exchange Notes on the date of the exchange that may be sold without restriction under federal securities laws (other than due solely to the status of such Holder as an affiliate of any of the Company or the Guarantors within the meaning of the Securities Act) and so notifies the Company and the Guarantors within 30 days after such Holder first becomes aware of such restrictions, in the case of each of clauses (i) to and including (iv) of this sentence, then the Company and the Guarantors shall promptly deliver to the Holders and the Trustee written -9- notice thereof (the "Shelf Notice") and shall file a Shelf Registration pursuant to Section 3 hereof. 3. Shelf Registration If at any time a Shelf Notice is delivered as contemplated by Section 2(c) hereof, then: (a) Shelf Registration. The Company and the Guarantors shall file with the SEC a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Notes not permitted to be exchanged in the Exchange Offer in accordance with the terms of this Agreement, Private Exchange Notes and Exchange Notes as to which Section 2(c)(iv) is applicable (the "Initial Shelf Registration"). The Company and the Guarantors shall use their reasonable efforts to file with the SEC the Initial Shelf Registration on or before the applicable Filing Date. The Initial Shelf Registration shall be on Form S-1 or another appropriate form permitting registration of such Registrable Notes for resale by Holders in the reasonable manner or manners designated by them (including, without limitation, one or more underwritten offerings). The Company and the Guarantors shall not permit any securities other than the Registrable Notes to be included in the Initial Shelf Registration or any Subsequent Shelf Registration (as defined below). The Company and the Guarantors shall use their reasonable efforts to cause the Initial Shelf Registration to be declared effective under the Securities Act on or prior to the Effectiveness Date and to keep the Initial Shelf Registration continuously effective under the Securities Act until the date which is two years from the Issue Date, subject to extension pursuant to the last paragraph of Section 5 hereof (the "Effectiveness Period"), or such shorter period ending when all Registrable Notes covered by the Shelf Registration have been sold in the manner set forth and as contemplated in the Initial Shelf Registration or, if applicable, a Subsequent Shelf Registration; provided, however, that the Effectiveness Period in respect of the Initial Shelf Registration shall be extended to the extent required to permit dealers to comply with the applicable prospectus delivery requirements of Rule 174 under the Securities Act and as otherwise provided herein and shall be subject to reduction to the extent that the applicable provisions of Rule 144(k) are amended or revised to reduce the two -10- year holding period set forth therein or any similar rule providing for a shorter holding period. No holder of Registrable Notes may include any of its Registrable Notes in any Shelf Registration Statement pursuant to this Agreement unless and until such holder furnishes to the Company and the Guarantors in writing, within 15 business days after receipt of a request therefor, such information as the Company and the Guarantors may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary prospectus included therein. No holder of Registrable Notes shall be entitled to Additional Interest pursuant to Section 4 hereof unless and until such holder shall have provided all such reasonably requested information. Each holder of Registrable Notes as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Company and the Guarantors all information required to be disclosed in order to make information previously furnished to the Company and the Guarantors by such Holder not a material misstatement or omission. (b) Subsequent Shelf Registrations. If the Initial Shelf Registration or any Subsequent Shelf Registration ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the securities registered thereunder), the Company and the Guarantors shall use their reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within 30 days of such cessation of effectiveness amend the Initial Shelf Registration in a manner to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional Shelf Registration Statement pursuant to Rule 415 covering all of the Registrable Notes covered by and not sold under the Initial Shelf Registration or an earlier Subsequent Shelf Registration (each, a "Subsequent Shelf Registration"). If a Subsequent Shelf Registration is filed, the Company and the Guarantors shall use their reasonable efforts to cause the Subsequent Shelf Registration to be declared effective under the Securities Act as soon as practicable after such filing and to keep such subsequent Shelf Registration continuously effective for a period equal to the number of days in the Effectiveness Period (subject to reduction as provided herein) less the aggregate number of days during which the Initial Shelf Registration or any Subsequent Shelf Registration was previously continuously effective. As used -11- herein the term "Shelf Registration" means the Initial Shelf Registration and any Subsequent Shelf Registration. (c) Supplements and Amendments. The Company and the Guarantors shall promptly supplement and amend any Shelf Registration if required by the rules, regulations or instructions applicable to the registration form used for such Shelf Registration, if required by the Securities Act, or if reasonably requested by the Holders of a majority in aggregate principal amount of the Registrable Notes covered by such Registration Statement or by any underwriter of such Registrable Notes. (d) Withdrawal of Stop Orders. If the Shelf Registration ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the securities registered thereunder), the Company and the Guarantors shall use their reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof. 4. Additional Interest (a) The Company, the Guarantors and the Initial Purchasers agree that the Holders will suffer damages if the Company and the Guarantors fail to fulfill their obligations under Section 2 or Section 3 hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company and the Guarantors agree to pay, as liquidated damages, additional interest on the Notes ("Additional Interest") under the circumstances and to the extent set forth below (each of which shall be given independent effect): (i) if (A) neither the Exchange Offer Registration Statement nor the Initial Shelf Registration has been filed on or prior to the Filing Date applicable thereto (i.e., 60 days after the Issue Date or delivery of the Shelf Notice, as applicable) or (B) notwith-standing that the Company and the Guarantors have consummated or will consummate the Exchange Offer, the Company and the Guarantors are required to file a Shelf Registration and such Shelf Registration is not filed on or prior to the Filing Date applicable thereto, then, commencing on the day after any such Filing Date, Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.50% per annum for the first 90 days immediately following such applicable Filing Date, and such Additional Interest rate -12- shall increase by an additional 0.50% per annum at the beginning of each subsequent 90-day period; or (ii) if (A) neither the Exchange Offer Registration Statement nor the Initial Shelf Registration is declared effective by the SEC on or prior to the Effectiveness Date applicable thereto (i.e., 150 days after the Issue Date or delivery of the Shelf Notice, as applicable) or (B) notwithstanding that the Company and the Guarantors have consummated or will consummate the Exchange Offer, the Company and the Guarantors are required to file a Shelf Registration and such Shelf Registration is not declared effective by the SEC on or prior to the Effectiveness Date applicable to such Shelf Registration, then, commencing on the day after such Effectiveness Date, Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.50% per annum for the first 90 days immediately following the day after such Effectiveness Date, and such Additional Interest rate shall increase by an additional 0.50% per annum at the beginning of each subsequent 90-day period; (iii) if (A) the Company and the Guarantors have not exchanged Exchange Notes for all Notes validly tendered in accordance with the terms of the Exchange Offer on or prior to the 195th day after the Issue Date or (B) if applicable, a Shelf Registration has been declared effective and such Shelf Registration ceases to be effective at any time during the Effectiveness Period, then Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.50% per annum for the first 90 days commencing on the (x) 196th day after the Issue Date, in the case of (A) above, or (y) the day such Shelf Registration ceases to be effective in the case of (B) above, and such Additional Interest rate shall increase by an additional 0.50% per annum at the beginning of each such subsequent 90-day period; provided, however, that the Additional Interest rate on the Notes may not exceed at any one time in the aggregate 1.0% per annum; provided, further, however, that (1) upon the filing of the applicable Exchange Offer Registration Statement or the applicable Shelf Registration as required hereunder (in the case of clause (i) above of this Section 4), (2) upon the effectiveness of the Exchange Offer Registration Statement or the applicable Shelf Registration Statement as required hereunder (in -13- the case of clause (ii) of this Section 4), or (3) upon the exchange of the Exchange Notes for all Notes tendered (in the case of clause (iii)(A) of this Section 4), or upon the effectiveness of the applicable Shelf Registration Statement which had ceased to remain effective (in the case of (iii)(B) of this Section 4), Additional Interest on the Notes in respect of which such events relate as a result of such clause (or the relevant subclause thereof), as the case may be, shall cease to accrue. (b) The Company and the Guarantors shall notify the Trustee within one business day after each and every date on which an event occurs in respect of which Additional Interest is required to be paid (an "Event Date"). Any amounts of Additional Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 4 will be payable in cash semi-annually on each March 15 and September 15 (to the holders of record on the March 1 and September 1 immediately preceding such dates), commencing with the first such date occurring after any such Additional Interest commences to accrue. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest rate by the principal amount of the Registrable Notes, multiplied by a fraction, the numerator of which is the number of days such Additional Interest rate was applicable during such period (determined on the basis of a 360-day year composed of twelve 30-day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of which is 360. 5. Registration Procedures In connection with the filing of any Registration Statement pursuant to Sections 2 or 3 hereof, the Company and the Guarantors shall effect such registrations to permit the sale of the securities covered thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Company and the Guarantors hereunder the Company and Guarantors shall: (a) Prepare and file with the SEC prior to the applicable Filing Date, a Registration Statement or Registration Statements as prescribed by Sections 2 or 3 hereof, and use its reasonable efforts to cause each such Registration Statement to become effective and remain effective as provided herein; provided, however, that, if -14- (1) such filing is pursuant to Section 3 hereof or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period relating thereto, before filing any Registration Statement or Prospectus or any amendments or supplements thereto, the Company and the Guarantors shall furnish to and afford the Holders of the Registrable Notes covered by such Registration Statement or BT Alex. Brown Incorporated (the "Representative") on behalf of such Participating Broker-Dealer, as the case may be, their or its counsel and the managing underwriters, if any, a reasonable opportunity to review copies of all such documents (including copies of any documents to be incorporated by reference therein and all exhibits thereto) proposed to be filed (in each case at least five business days prior to such filing, or such later date as is reasonable under the circumstances). The Company and the Guarantors shall not file any Registration Statement or Prospectus or any amendments or supplements thereto if the Holders of a majority in aggregate principal amount of the Registrable Notes covered by such Registration Statement, their counsel, or the managing underwriters, if any, shall reasonably object. (b) Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration Statement or Exchange Offer Registration Statement, as the case may be, as may be necessary to keep such Registration Statement continuously effective for the Effectiveness Period or the Applicable Period or until consummation of the Exchange Offer, as the case may be; cause the related Prospectus to be supplemented by any Prospectus supplement required by applicable law, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; and comply with the provisions of the Securities Act and the Exchange Act applicable to it with respect to the disposition of all securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented and with respect to the subsequent resale of any securities being sold by a Participating Broker-Dealer covered by any such Prospectus. The Company and the Guarantors shall be deemed not to have used their reasonable efforts to keep a Registration Statement effective during the Effective Pe- -15- riod or the Applicable Period, as the case may be, relating thereto if the Company and the Guarantors voluntarily take any action that would result in selling Holders of the Registrable Notes covered thereby or Participating Broker-Dealers seeking to sell Exchange Notes not being able to sell such Registrable Notes or such Exchange Notes during that period unless (i) such action is required by applicable law or (ii) the Company and the Guarantors comply with this Agreement, including without limitation, the provisions of Section 5(k) or the last paragraph of this Section 5. (c) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period relating thereto from whom the Company and the Guarantors have received written notice that it will be a Participating Broker-Dealer in the Exchange Offer, notify the selling Holders of Registrable Notes, or the Representative on behalf of such Participating Broker-Dealer, as the case may be, their or its counsel and the managing underwriters, if any, promptly (but in any event within two business days), and confirm such notice in writing, (i) when a Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective under the Securities Act (including in such notice a written statement that any Holder may, upon request, obtain, at the sole expense of the Company and the Guarantors, one conformed copy of such Registration Statement or post-effective amendment including financial statements and schedules, documents incorporated or deemed to be incorporated by reference therein and exhibits), (ii) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of any preliminary prospectus or the initiation of any proceedings for that purpose, (iii) if at any time when a prospectus is required by the Securities Act to be delivered in connection with sales of the Registrable Notes or resales of Exchange Notes by Participating Broker-Dealers the representations and warranties of the Company and the Guarantors contained in any agreement (including any underwriting -16- agreement) contemplated by Section 5(m) hereof cease to be true and correct in all material respects, (iv) of the receipt by the Company and the Guarantors of any notification with respect to the suspension of the qualification or exemption from qualification of a Registration Statement or any of the Registrable Notes or the Exchange Notes to be sold by any Participating Broker-Dealer for offer or sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose, (v) of the happening of any event, the existence of any condition or any information becoming known that makes any statement made in such Registration Statement or related Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in or amendments or supplements to such Registration Statement, Prospectus or documents so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (vi) of any of the Company's and the Guarantors' determination that a post-effective amendment to a Registration Statement would be appropriate. (d) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, use its reasonable efforts to prevent the issuance of any order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of a Prospectus or suspending the qualification (or exemption from qualification) of any of the Registrable Notes or the Exchange Notes to be sold by any Participating Broker-Dealer, for sale in any jurisdiction, and, if any such order is issued, to use its reasonable efforts to obtain the withdrawal of any such order at the earliest possible date. -17- (e) If a Shelf Registration is filed pursuant to Section 3 and if requested by the managing underwriter or underwriters (if any), the Holders of a majority in aggregate principal amount of the Registrable Notes being sold in connection with an underwritten offering or any Participating Broker-Dealer, (i) promptly as practicable incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters (if any), such Holders, any Participating Broker-Dealer or counsel for any of them reasonably request to be included therein, (ii) make all required filings of such prospectus supplement or such post-effective amendment as soon as practicable after the Company and the Guarantors have received notification of the matters to be incorporated in such prospectus supplement or post-effective amendment, and (iii) supplement or make amendments to such Registration Statement.

(g) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, deliver to each selling Holder of Registrable Notes, or each such Participating Broker-Dealer, as the case may be, their respective counsel, and the underwriters, if any, at the sole expense of the Company and the Guarantors, as many copies of the Prospectus or Prospectuses (including each form of preliminary prospectus) and each amendment or sup- -18- plement thereto and any documents incorporated by reference therein as such Persons may reasonably request; and, subject to the last paragraph of this Section 5, the Company and the Guarantors hereby consent to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders of Registrable Notes or each such Participating Broker-Dealer, as the case may be, and the underwriters or agents, if any, and dealers (if any), in connection with the offering and sale of the Registrable Notes covered by, or the sale by Participating Broker-Dealers of the Exchange Notes pursuant to, such Prospectus and any amendment or supplement thereto. (h) Prior to any public offering of Registrable Notes or any delivery of a Prospectus contained in the Exchange Offer Registration Statement by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, to use its reasonable efforts to register or qualify, and to cooperate with the selling Holders of Registrable Notes or the Representative on behalf of such Participating Broker-Dealer, as the case may be, the managing underwriter or underwriters, if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Notes for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any selling Holder, Participating Broker-Dealer, or the managing underwriter or underwriters reasonably request in writing; provided, however, that where Exchange Notes held by Participating Broker-Dealers or Registrable Notes are offered other than through an underwritten offering, the Company and the Guarantors agree to cause its counsel to perform Blue Sky investigations and file registrations and qualifications required to be filed pursuant to this Section 5(h); keep each such registration or qualification (or exemption therefrom) effective during the period such Registration Statement is required to be kept effective and do any and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of the Exchange Notes held by Participating Broker-Dealers or the Registrable Notes covered by the applicable Registration Statement; provided, however, that the Company and the Guarantors shall not be required to (A) qualify generally to do business in any jurisdiction where it is not then so qualified, (B) take any action that would subject it to -19- general service of process in any such jurisdiction where it is not then so subject or (C) subject itself to taxation in excess of a nominal dollar amount in any such jurisdiction where it is not then so subject. (i) If a Shelf Registration is filed pursuant to Section 3 hereof, cooperate with the selling Holders of Registrable Notes and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Notes to be sold, which certificates shall not bear any restrictive legends and shall be in a form eligible for deposit with The Depository Trust Company; and enable such Registrable Notes to be in such denominations and registered in such names as the managing underwriter or underwriters, if any, or Holders may reasonably request.

(k) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, upon the occurrence of any event contemplated by paragraph 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable prepare and (subject to Section 5(a) hereof) file with the SEC, at the sole expense of the Company and the Guarantors, a supplement or post-effective amendment to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Notes being sold thereunder or to the purchasers of -20- the Exchange Notes to whom such Prospectus will be delivered by a Participating Broker-Dealer, any such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. (l) Prior to the effective date of the first Registration Statement relating to the Registrable Notes, (i) provide the Trustee with certificates for the Registrable Notes or Exchange Notes, as the case may be, in a form eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP number for the Registrable Notes or Exchange Notes, as the case may be.

The above shall be done at each closing under such underwriting agreement, or as and to the extent required thereunder. (n) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, make available for inspection by any selling Holder of such Registrable Notes being sold, or each such Participating Broker-Dealer, as the case may be, any underwriter participating in any such disposition of Registrable Notes, if any, and any attorney, accountant or other agent retained by any such selling Holder or each such Participating Broker-Dealer, as the case may be, or underwriter (collectively, the "Inspectors"), at the offices where normally kept, during reasonable business hours, all financial and other records, pertinent corporate documents and instruments of the Company, the Guarantors and their subsidiaries (collectively, the "Records") as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the offi- -22- cers, directors and employees of the Company, the Guarantors and their subsidiaries to supply all information reasonably requested by any such Inspector in connection with such Registration Statement and Prospectus. Each Inspector shall agree in writing that it will keep the Records confidential and that it will not disclose any of the Records unless (i) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in such Registration Statement or Prospectus, (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, or (iii) the information in such Records has been made generally available to the public. Each selling Holder of such Registrable Notes and each such Participating Broker-Dealer will be required to agree that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Company and the Guarantors unless and until such information is made generally available to the public. Each selling Holder of such Registrable Notes and each such Participating Broker-Dealer will be required to further agree that it will, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, give notice to the Company and the Guarantors and allow the Company and the Guarantors to undertake appropriate action to prevent disclosure of the Records deemed confidential at the Company's and the Guarantors' expense. (o) Provide an indenture trustee for the Registrable Notes or the Exchange Notes, as the case may be, and cause the Indenture or the trust indenture provided for in Section 2(a) hereof, as the case may be, to be qualified under the TIA not later than the effective date of the first Registration Statement relating to the Registrable Notes; and in connection therewith, cooperate with the trustee under any such indenture and the Holders of the Registrable Notes, to effect such changes to such indenture as may be required for such indenture to be so qualified in accordance with the terms of the TIA; and execute, and use its best efforts to cause such trustee to execute, all documents as may be required to effect such changes, and all other forms and documents required to be filed with the SEC to enable such indenture to be so qualified in a timely manner. -23- (p) Comply with all applicable rules and regulations of the SEC and make generally available to their respective securityholders earnings statements satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) (i) commencing at the end of any fiscal quarter in which Registrable Notes are sold to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter of the Company and the Guarantors after the effective date of a Registration Statement, which statements shall cover said 12-month periods. (q) If the Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Registrable Notes by Holders to the Company and the Guarantors (or to such other Person as directed by the Company and the Guarantors) in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be, the Company and the Guarantors shall mark, or cause to be marked, on such Registrable Notes that such Registrable Notes are being cancelled in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be; in no event shall such Registrable Notes be marked as paid or otherwise satisfied. (r) Use its reasonable efforts to cause the Registrable Notes covered by a Registration Statement to be rated with the appropriate rating agencies, if so requested by the managing underwriter or underwriters, if any. (s) Cooperate with the managing underwriter, if any, participating in the disposition of Registrable Notes and its counsel in connection with any filings required to be made with the National Association of Securities Dealers, Inc. (the "NASD"). (t) Use its reasonable efforts to take all other steps reasonably necessary to effect the registration of the Exchange Notes and/or Registrable Notes covered by a Registration Statement contemplated hereby. -24- The Company and the Guarantors may require each seller of Registrable Notes as to which any registration is being effected to furnish to the Company and the Guarantors such information regarding such seller and the distribution of such Registrable Notes as the Company and the Guarantors may, from time to time, reasonably request. The Company and the Guarantors may exclude from such registration the Registrable Notes of any seller so long as such seller fails to furnish such information within a reasonable time after receiving such request. Each seller as to which any Shelf Registration is being effected agrees to furnish promptly to the Company and the Guarantors all information required to be disclosed in order to make the information previously furnished to the Company and the Guarantors by such seller not to contain a material misstatement or omission. Each Holder of Registrable Notes and each Participating Broker-Dealer agrees by its acquisition of such Registrable Notes or Exchange Notes to be sold by such Participating Broker-Dealer, as the case may be, that, upon actual receipt of any notice from the Company and the Guarantors of the happening of any event of the kind described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or 5(c)(vi) hereof, such Holder will forthwith discontinue disposition of such Registrable Notes covered by such Registration Statement or Prospectus or Exchange Notes to be sold by such Holder or Participating Broker-Dealer, as the case may be, and the dissemination of the applicable Prospectus until such Holder's or Participating Broker-Dealer's receipt of the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof, or until it is advised in writing (the "Advice") by the Company and the Guarantors that the use of the applicable Prospectus may be resumed. In the event that the Company and the Guarantors shall give any such notice, each of the Effectiveness Period and the Applicable Period shall be extended by the number of days during such periods from and including the date of the giving of such notice to and including the date when each seller of Registrable Notes covered by such Registration Statement or Exchange Notes to be sold by such Participating Broker-Dealer, as the case may be, shall have received (x) the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof or (y) the Advice. -25- 6. Registration Expenses All fees and expenses incident to the performance of or compliance with this Agreement by the Company and the Guarantors shall be borne by the Company and the Guarantors whether or not the Exchange Offer Registration Statement or any Shelf Registration Statement is filed or becomes effective or the Exchange Offer is consummated, including, without limitation, (i) all registration and filing fees (including, without limitation, (A) fees with respect to filings required to be made with the NASD in connection with an underwritten offering and (B) fees and expenses of compliance with state securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements of counsel in connection with Blue Sky qualifications of the Registrable Notes or Exchange Notes and determination of the eligibility of the Registrable Notes or Exchange Notes for investment under the laws of such jurisdictions (x) where the holders of Registrable Notes are located, in the case of the Exchange Notes, or (y) as provided in Section 5(h) hereof, in the case of Registrable Notes or Exchange Notes to be sold by a Participating Broker-Dealer during the Applicable Period)), (ii) printing expenses, including, without limitation, expenses of printing certificates for Registrable Notes or Exchange Notes in a form eligible for deposit with The Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by the managing underwriter or underwriters, if any, by the Holders of a majority in aggregate principal amount of the Registrable Notes included in any Registration Statement or in respect of Exchange Notes to be sold by any Participating Broker-Dealer during the Applicable Period, as the case may be, (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Company and the Guarantors and, in the case of a Shelf Registration, reasonable fees and disbursements of one special counsel for all of the sellers of Registrable Notes (exclusive of any counsel retained pursuant to Section 7 hereof), (v) fees and disbursements of all independent certified public accountants referred to in Section 5(m)(iii) hereof (including, without limitation, the expenses of any special audit and "cold comfort" letters required by or incident to such performance), (vi) Securities Act liability insurance, if the Company and the Guarantors desire such insurance, (vii) fees and expenses of all other Persons retained by the Company and the Guarantors, (viii) internal expenses of the Company and the Guarantors (including, without limitation, all salaries and expenses of officers and employees of the Company and the Guarantors per- -26- forming legal or accounting duties), (ix) the expense of any annual audit, (x) the fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange, and the obtaining of a rating of the securities, in each case, if applicable, and (xi) the expenses relating to printing, word processing and distributing all Registration Statements, underwriting agreements, indentures and any other documents necessary in order to comply with this Agreement. 7. Indemnification (a) The Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless each Holder of Registrable Notes and each Participating Broker-Dealer selling Exchange Notes during the Applicable Period, the officers, directors, employees and agents of each such Person, and each Person, if any, who controls any such Person within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a "Participant"), from and against any and all losses, claims, damages, judgments, liabilities and expenses (including, without limitation, the reasonable legal fees and other expenses actually incurred in connection with any suit, action or proceeding or any claim asserted) caused by, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) or Prospectus (as amended or supplemented if the Company and the Guarantors shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by, arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus in the light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities are caused by, arise out of or are based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Participant furnished to the Company or the Guarantors in writing by such Participant expressly for use therein; provided, however, that the Company and the Guarantors will not be liable if such untrue statement or omission or alleged untrue statement or omission was contained or made in any preliminary prospectus and corrected in the final Prospectus or any amendment or supplement thereto and any such loss, liability, claim, or damage or expense suffered or incurred by the -27- Participants resulted from any action, claim or suit by any Person who purchased Registrable Notes or Exchange Notes which are the subject thereof from such Participant and such Participant failed to deliver or provide a copy of the final Prospectus (as amended or supplemented) to such Person with or prior to the confirmation of the sale of such Registrable Notes or Exchange Notes sold to such Person if required by applicable law, unless such failure to deliver or provide a copy of the final Prospectus (as amended or supplemented) was a result of noncompliance by the Company and the Guarantors with Section 5 of this Agreement. (b) Each Participant agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors, their respective directors, their respective officers who sign the Registration Statement and each Person who controls the Company or the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company and the Guarantors to each Participant, but only with reference to information relating to such Participant furnished to the Company or the Guarantors in writing by such Participant expressly for use in any Registration Statement or Prospectus, any amendment or supplement thereto, or any preliminary prospectus. The liability of any Participant under this paragraph shall in no event exceed the proceeds received by such Participant from sales of Registrable Notes or Exchange Notes giving rise to such obligations. (c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such Person (the "Indemnified Person") shall promptly notify the Persons against whom such indemnity may be sought (the "Indemnifying Persons") in writing, and the Indemnifying Persons shall be entitled to, and upon request of the Indemnified Person shall, retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Persons may reasonably designate in such proceeding and shall pay the reasonable fees and expenses actually incurred by such counsel related to such proceeding; provided, however, that the failure to so notify the Indemnifying Persons shall not relieve any of them of any obligation or liability which any of them may have hereunder or otherwise except to the extent it is materially prejudiced by -28- such failure. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Persons and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Persons shall have failed within a reasonable period of time to retain counsel reasonably satisfactory to the Indemnified Person or (iii) the named parties in any such proceeding (including any impleaded parties) include both any Indemnifying Person and the Indemnified Person or any affiliate thereof and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicting interests between them. It is understood that, unless there exists a conflict among Indemnified Persons, the Indemnifying Persons shall not, in connection with such proceeding or separate but substantially similar related proceeding in the same jurisdiction arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed promptly as they are incurred. Any such separate firm for the Participants and such control Persons of Participants shall be designated in writing by Participants who sold a majority in interest of Registrable Notes and Exchange Notes sold by all such Participants and shall be reasonably acceptable to the Company and any such separate firm for the Company or the Guarantors, their respective directors, their respective officers and such control Persons of the Company and the Guarantors shall be designated in writing by the Company and the Guarantors and shall be reasonably acceptable to the Holders. The Indemnifying Persons shall not be liable for any settlement of any proceeding effected without its prior written consent (which consent shall not be unreasonably withheld or delayed), but if settled with such consent or if there be a final non-appealable judgment for the plaintiff for which the Indemnified Person is entitled to indemnification pursuant to this Agreement, each of the Indemnifying Persons agrees to indemnify and hold harmless each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified Person for reasonable fees and expenses actually incurred by counsel as contemplated by the third sentence of this paragraph, the Indemnifying Person agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered -29- into more than 30 days after receipt by such Indemnifying Person of the aforesaid request and (ii) such Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement; provided, however, that the Indemnifying Person shall not be liable for any settlement effected without its consent pursuant to this sentence if the Indemnifying Person is contesting, in good faith, the request for reimbursement. No Indemnifying Person shall, without the prior written consent of the Indemnified Persons (which consent shall not be unreasonably withheld or delayed), effect any settlement or compromise of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party, or indemnity could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional written release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of such Indemnified Person. (d) If the indemnification provided for in clauses (a) and (b) of this Section 7 is for any reason unavailable to, or insufficient to hold harmless, an Indemnified Person in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraphs, in lieu of indemnifying such Indemnified Person thereunder and in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect (i) the relative benefits received by the Indemnifying Person or Persons on the one hand and the Indemnified Person or Persons on the other from the offering of the Notes or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the Indemnifying Person or Persons on the one hand and the Indemnified Person or Persons on the other in connection with the misstatements or omissions or alleged misstatements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a -30- material fact relates to information supplied by the Company and the Guarantors on the one hand or such Participant or such other Indemnified Person, as the case may be, on the other, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such misstatement or omission, and any other equitable considerations appropriate in the circumstances. (e) The parties agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Participants were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages, judgments, liabilities and expenses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses actually incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall a Participant be required to contribute any amount in excess of the amount by which proceeds received by such Participant from sales of Registrable Notes or Exchange Notes, as the case may be, exceeds the amount of any damages that such Participant has otherwise been required to pay or has paid by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. (f) Any losses, claims, damages, liabilities or expenses for which an Indemnified Person is entitled to indemnification or contribution under this Section 7 shall be paid by the Indemnifying Person to the Indemnified Person as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Company and the Guarantors set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Holder or any person who controls a Holder, the Company or the Guarantors and their respective directors, officers, employees or agents or any per- -31- son controlling the Company or the Guarantors, and (ii) any termination of this Agreement. (g) The indemnity and contribution agreements contained in this Section 7 will be in addition to any liability which the Indemnifying Persons may otherwise have to the Indemnified Persons referred to above. 8. Rules 144 and 144A The Company and the Guarantors covenant and agree that, so long as Registrable Notes remain outstanding, it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, if at any time the Company and the Guarantors are not permitted to file such reports, the Company and the Guarantors will, upon the request of any Holder or beneficial owner of Registrable Notes, make publicly available annual reports and such information, documents and other reports of the type specified in Sections 13 and 15(d) of the Exchange Act. The Company and the Guarantors further covenant for so long as any Registrable Notes remain outstanding, to make available to any Holder or beneficial owner of Registrable Notes in connection with any sale thereof and any prospective purchaser of such Registrable Notes from such Holder or beneficial owner the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Registrable Notes pursuant to Rule 144A. 9. Underwritten Registrations If any of the Registrable Notes covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will manage the offering will be selected by the Company and the Guarantors and shall be reasonably acceptable to the Holders of a majority in aggregate principal amount of such Registrable Notes included in such offering. No Holder of Registrable Notes may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's Registrable Notes on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and -32- (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements. 10. Miscellaneous (a) No Inconsistent Agreements. As of the date hereof, the Company and the Guarantors will not enter into any agreement with respect to any of its securities that is inconsistent with the rights granted to the Holders of Registrable Notes in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of any of the Company's and the Guarantors' other issued and outstanding securities. As of the date hereof, the Company and the Guarantors have not entered and the Company and Guarantors will not enter into any agreement with respect to any of its securities which will grant to any Person piggy-back registration rights with respect to any Registration Statement required to be filed by the Company and the Guarantors pursuant to this Agreement. (b) Adjustments Affecting Registrable Notes. The Company and the Guarantors shall not, directly or indirectly, take any action with respect to the Registrable Notes as a class that would adversely affect the ability of the Holders of Registrable Notes to include such Registrable Notes in a registration undertaken pursuant to this Agreement. (c) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, otherwise than with the prior written consent of (I) the Company and the Guarantors and (II)(A) the Holders of not less than a majority in aggregate principal amount of the then outstanding Registrable Notes and (B) in circumstances that would adversely affect the Participating Broker-Dealers, the Participating Broker-Dealers holding not less than a majority in aggregate principal amount of the Exchange Notes held by all Participating Broker-Dealers; provided, however, that Section 7 and this Section 10(c) may not be amended, modified or supplemented without the prior written consent of each Holder and each Participating Broker-Dealer (including any person who was a Holder or Participating Broker-Dealer of Registrable Notes or Exchange Notes, as the case may be, disposed of pursuant to any Registration Statement) affected by any such -33- amendment, modification or supplement. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of Registrable Notes whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders of Registrable Notes may be given by Holders of at least a majority in aggregate principal amount of the Registrable Notes being sold pursuant to such Registration Statement.

Subject to, and effective upon, the acceptance for exchange of the Old Notes tendered hereby, the undersigned hereby irrevocably sells, assigns and transfers to or upon the order of the Company all right, title and interest in and to such Old Notes, and hereby irrevocably constitutes and appoints the Exchange Agent the true and lawful agent and attorney-in-fact of the undersigned (with full knowledge that said Exchange Agent also acts as the agent of the Company and as Trustee under the indenture governing the Old Notes and the Exchange Notes) with respect to such Old Notes, with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest) to (a) deliver certificates representing such Old Notes, and to deliver all accompanying evidences of transfer and authenticity to or upon the order of the Company upon receipt by the Exchange Agent, as the undersigned's agent, of the Exchange Notes to which the undersigned is entitled upon the acceptance by the Company of such Old Notes for exchange pursuant to the Exchange Offer, (b) receive all benefits and otherwise to exercise all rights of beneficial ownership of such Old Notes, all in accordance with the terms of the Exchange Offer, and (c) present such Old Notes for transfer on the register for such Old Notes. The undersigned acknowledges that prior to this Exchange Offer, there has been no public market for the Old Notes or the Exchange Notes. If a market for the Exchange Notes should develop, the Exchange Notes could trade at a discount from their principal amount. The undersigned is aware that the Company does not intend to list the Exchange Notes on a national securities exchange and that there can be no assurance that an active market for the Exchange Notes will develop. The undersigned also acknowledges that this Exchange Offer is being made in reliance on an interpretation by the staff of the Securities and Exchange Commission (the "Commission") that the Exchange Notes issued pursuant to the Exchange Offer in exchange for the Old Notes may be offered for resale, resold and otherwise transferred by any person receiving such Exchange Notes whether or not such person is the holder thereof, (other than any such holder or other person which is (i) a broker-dealer that receives Exchange Notes for its own account in exchange for Old Notes, where such Old Notes were acquired by such broker-dealer as a result of market-making or other trading activities, or (ii) an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act of 1933, as amended (the "Securities Act")) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such Exchange Notes are acquired in the ordinary course of business of such holder or other person, such holder or other person is not engaged in or intending to engage in a distribution of the Exchange Notes, and such holder or other person has no arrangement with any person to participate in the distribution of such Exchange Notes. See Morgan Stanley & Co. Incorporated, SEC No-Action Letter (available June 5, 1991) and Exxon Capital Holdings Corporation, SEC No-Action Letter (available May 13, 1988). If the undersigned is not a broker-dealer, the undersigned represents that it is not engaged in, and does not intend to engage in, a distribution of Exchange Notes. If the undersigned is a broker-dealer that will receive Exchange Notes, it represents that the Old Notes to be exchanged for Exchange Notes were acquired as a result of market-making activities or other trading activities and it acknowledges that it will deliver a prospectus in connection with any resale of such Exchange Notes; however, by so acknowledging and by delivering a prospectus, the undersigned will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. The Exchange Offer is not being made to, nor will tenders be accepted from or on behalf of, holders of the Old Notes in any jurisdiction in which the making of the Offer or acceptance thereof would not be in compliance with the laws of such jurisdiction or would otherwise not be in compliance with any provision of any applicable security law. The undersigned represents that (a) the Exchange Notes acquired pursuant to the Exchange Offer are being obtained in the ordinary course of business of the undersigned or other person receiving such Exchange Notes, (b) neither the undersigned nor any such other person is engaged in or intends to engage in a distribution of such 4 Exchange Notes, (c) neither the undersigned nor any such other person has any arrangement or understanding with any person to participate in a distribution of the Exchange Notes and (d) neither the undersigned nor any such other person is an "affiliate" as defined under Rule 405 of the Securities Act, of the Company, its subsidiaries or The Renco Group, Inc., the parent corporation of the Company, or if such holder is such an affiliate, that such holder will comply with the registration and the prospectus delivery requirements of the Securities Act in connection with the disposition of any Exchange Notes to the extent applicable. The undersigned understands and acknowledges that the Company reserves the right in its sole discretion to purchase or make offers for any Old Notes that remain outstanding subsequent to the Expiration Date or, as set forth in the Prospectus under the caption "Conditions of the Exchange Offer," to terminate the Exchange Offer and, to the extent permitted by applicable law, purchase Old Notes in the open market, in privately negotiated transactions or otherwise. The terms of any such purchases or offers will differ from the terms of the Exchange Offer. The undersigned hereby represents and warrants that the undersigned accepts the terms and conditions of the Exchange Offer, has full power and authority to tender, exchange, assign and transfer the Old Notes tendered hereby, and that when the same are accepted for exchange by the Company, the Company will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim or right. The undersigned will, upon request, execute and deliver any additional documents deemed by the Exchange Agent or the Company to be necessary or desirable to complete the sale, assignment and transfer of the Old Notes tendered hereby. The undersigned agrees that all authority conferred or agreed to be conferred by this Letter of Transmittal and every obligation of the undersigned hereunder shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of the undersigned and shall not be affected by, and shall survive, the death or incapacity of the undersigned. The undersigned also agrees that, except as stated in the Prospectus, the Old Notes tendered hereby cannot be withdrawn. The undersigned understands that tenders of the Old Notes pursuant to any one of the procedures described in the Prospectus under the caption "The Exchange Offer--Procedures for Tendering" and in the instructions hereto will constitute a binding agreement between the undersigned and the Company in accordance with the terms and subject to the conditions of the Exchange Offer. The undersigned understands that by tendering Old Notes pursuant to one of the procedures described in the Prospectus and the instructions hereto, the tendering holder will be deemed to have waived the right to receive any payment in respect of interest on the Old Notes accrued up to the date of issuance of the Exchange Notes. The undersigned recognizes that, under certain circumstances set forth in the Prospectus, the Company may not be required to accept for exchange any of the Old Notes tendered. Old Notes not accepted for exchange or withdrawn will be returned to the undersigned at the address set forth below unless otherwise indicated under "Special Delivery Instructions" below. Unless otherwise indicated herein under the box entitled "Special Issuance Instructions" below, Exchange Notes, and Old Notes not validly tendered or accepted for exchange, will be issued in the name of the undersigned. Similarly, unless otherwise indicated under the box entitled "Special Delivery Instructions" below, Exchange Notes, and Old Notes not validly tendered or accepted for exchange, will be delivered to the undersigned at the address shown below the signature of the undersigned. The undersigned recognizes that the Company has no obligation pursuant to the "Special Issuance Instructions" to transfer any Old Notes from the name of the registered holder thereof if the Company does not accept for exchange any of the principal amount of such Old Notes so tendered. All questions as to the validity, form, eligibility (including time of receipt), and withdrawal of the tendered Old Notes will be determined by the Company in its sole discretion, which determination will be final and binding. The Company reserves the absolute right to reject any and all Old Notes not properly tendered or any Old Notes the Company's acceptance of which would, in the opinion of counsel for the Company, be unlawful. The Company also reserves the right to waive any irregularities or conditions of tender as to particular Old Notes. The Company's interpretation of the terms and conditions of the Exchange Offer (including the instructions in this Letter of Transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in 5 connection with tenders of Old Notes must be cured within such time as the Company shall determine. Neither the Company, the Exchange Agent nor any other person shall be under any duty to give notification of defects or irregularities with respect to tenders of Old Notes, nor shall any of them incur any liability for failure to give such notification. Tenders of Old Notes will not be deemed to have been made until such irregularities have been cured or waived. Any Old Notes received by the Exchange Agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned without cost to such holder by the Exchange Agent to the tendering holders of Old Notes, unless otherwise provided in this Letter of Transmittal, as soon as practicable following the Expiration Date. 6 THE UNDERSIGNED, BY COMPLETING THE BOX ON THE COVER ENTITLED "DESCRIPTION OF OLD NOTES TENDERED" AND SIGNING THIS LETTER OF TRANSMITTAL, WILL BE DEEMED TO HAVE TENDERED THE OLD NOTES AND MADE CERTAIN REPRESENTATIONS (INCLUDING AS TO FINANCIAL STATUS) DESCRIBED IN THE PROSPECTUS AND HEREIN. - -------------------------------------------------------------------------------- SIGN HERE (To Be Completed by All Tendering Holders) X -------------------------------------------------------------------------- X -------------------------------------------------------------------------- (Signature(s) of Holder(s) or Authorized Signatory) Must be signed by the registered holder(s) of Old Notes exactly as their name(s) appear(s) on certificate(s) for the Old Notes or by person(s) authorized to become registered holder(s) by endorsements and documents transmitted with this Letter of Transmittal.

Delivery of this Letter of Transmittal and Certificates; Guaranteed Delivery Procedures. To be effectively tendered pursuant to the Exchange Offer, the Old Notes, together with a properly completed Letter of Transmittal (or facsimile thereof), duly executed by the registered holder thereof, and any other documents required by this Letter of Transmittal, must be received by the Exchange Agent at one of its addresses set forth on the front page of this Letter of Transmittal. If the beneficial owner of any Old Notes is not the registered holder, then such person may validly tender his or her Old Notes only by obtaining and submitting to the Exchange Agent a properly completed Letter of Transmittal from the registered holder. Old Notes should be delivered only to the Exchange Agent and not to the Company or to any other person. The method of delivery of Old Notes and all other required documents to the Exchange Agent is at the election and risk of the holder, but if such delivery is by mail, it is suggested that the holder use properly insured, registered or certified mail with return receipt requested. Instead of delivery by mail, it is recommended that Old Notes be delivered by hand or by courier. If certificates for Old Notes are sent by mail, it is suggested that the mailing be made sufficiently in advance of the Expiration Date to permit delivery to the Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration Date. If a holder desires to tender Old Notes and such holder's Old Notes are not immediately available or time will not permit such holder's Letter of Transmittal, Old Notes or other required documents to reach the Exchange Agent on or before the Expiration Date, such holder's tender may be effected if: (a) such tender is made by or through an Eligible Institution (as defined); (b) on or prior to the Expiration Date, the Exchange Agent has received a properly completed and duly executed Notice of Guaranteed Delivery (by facsimile transmission, mail or hand delivery) from such Eligible Institution setting forth the name and address of the holder of such Old Notes, the certificate numbers of such Old Notes (if available) and the principal amount of Old Notes tendered and stating that the tender is being made thereby and guaranteeing that, within three business days after the Expiration Date, a duly executed Letter of Transmittal, or facsimile thereof, together with the Old Notes, and any other documents required by this Letter of Transmittal and the instructions hereto, will be deposited by such Eligible Institution with the Exchange Agent; and (c) this Letter of Transmittal (or facsimile thereof), a Notice of Guaranteed Delivery and Old Notes, in proper form for transfer, and all other required documents are received by the Exchange Agent within three business days after the date of such telegram, facsimile transmission or letter. 2. Withdrawal of Tenders. Tendered Old Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date, unless previously accepted for exchange. To be effective, a written or facsimile transmission notice of withdrawal must (a) be received by the Exchange Agent at one of its addresses set forth on the first page of this Letter of Transmittal prior to 5:00 p.m., New York City time, on the Expiration Date, unless previously accepted for exchange, (b) specify the name of the person who tendered the Old Notes, (c) contain the description of the Old Notes to be withdrawn, the certificate numbers shown on the particular certificates evidencing such Old Notes and the aggregate principal amount represented by such Old Notes and (d) be signed by the holder of such Old Notes in the same manner as the original signature appears on this Letter of Transmittal (including any required signature guarantees) or be accompanied by evidence sufficient to have the Trustee with respect to the Old Notes register the transfer of such Old Notes into the name of the holder withdrawing the tender. The signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution unless such Old Notes have been tendered (a) by a registered holder of Old Notes who has not completed either the box entitled "Special Issuance Instructions" or the box entitled "Special Delivery Instructions" on this Letter of Transmittal or (b) for the account of an Eligible Institution. All questions as to the validity, form and eligibility (including time of receipt) of such withdrawal notices shall be determined by the 9 Company, whose determination shall be final and binding on all parties. If the Old Notes to be withdrawn have been delivered or otherwise identified to the Exchange Agent, a signed notice of withdrawal is effective immediately upon receipt by the Exchange Agent of a written or facsimile transmission notice of withdrawal even if physical release is not yet effected. In addition, such notice must specify, in the case of Old Notes tendered by delivery of certificates for such Old Notes, the name of the registered holder (if different from that of the tendering holder) to be credited with the withdrawn Old Notes. Withdrawals may not be rescinded, and any Old Notes withdrawn will thereafter be deemed not validly tendered for purposes of the Exchange Offer. However, properly withdrawn Old Notes may be retendered by following one of the procedures described under "The Exchange Offer--Procedures for Tendering" in the Prospectus at any time on or prior to the applicable Expiration Date. 3. Signatures on this Letter of Transmittal, Bond Powers and Endorsements; Guarantee of Signatures. If this letter of Transmittal is signed by the registered holder(s) of the Old Notes tendered hereby, the signature must correspond exactly with the name(s) as written on the face of the certificates without any change whatsoever. If any Old Notes tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal. If any Old Notes tendered hereby are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate copies of this Letter of Transmittal as there are different registrations of certificates. When this Letter of Transmittal is signed by the registered holder or holders specified herein and tendered hereby, no endorsements of certificates or separate bond powers are required unless Exchange Notes are to be issued, or certificates for any untendered principal amount of Old Notes are to be reissued, to a person other than the registered holder. If this Letter of Transmittal is signed by a person other than the registered holder(s) of any certificate(s) specified herein such certificates(s) must be endorsed or accompanied by appropriate bond powers, in either case signed exactly as the name(s) of the registered holder(s) appear(s) on the certificate(s). If this Letter of Transmittal or a Notice of Guaranteed Delivery or any certificates or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and unless waived by the Company, proper evidence satisfactory to the Company of their authority so to act must be submitted. Except as described below, signatures on this Letter of Transmittal or a notice of withdrawal, as the case may be, must be guaranteed by an Eligible Institution. Signatures on this Letter of Transmittal or a notice of withdrawal, as the case may be, need not be guaranteed if the Old Notes tendered pursuant hereto are tendered (a) by a registered holder of Old Notes who has not completed either the box entitled "Special Issuance Instructions" or the box entitled "Special Delivery Instructions" on this Letter of Transmittal or (b) for the account of an Eligible Institution. In the event that signatures on this Letter of Transmittal or a notice of withdrawal, as the case may be, are required to be guaranteed, such guarantee must be by a firm which is a member of a registered national securities exchange or a member of the National Association of Securities Delivers, Inc. or by a commercial bank or trust company having an office or correspondent in the Untied States (each as "Eligible Institutions"). Endorsements on certificates for Old Notes or signatures on bond powers required by this Instruction 3 must be guaranteed by an Eligible Institution. 4. Special Issuance and Delivery Instructions. Tendering holders should indicate in the applicable box the name and address to which certificates for Exchange Notes and/or substitute certificates evidencing Old Notes for the principal amounts not exchanged are to be issued or sent, if different from the name and address of the person signing this Letter of Transmittal. In the case of issuance in a different name, the employer identification or social security number of the person named must also be indicated. If no such instructions are given, any Old Notes not exchanged will be returned to the name and address of the person signing this Letter of Transmittal. 10 5. Tax Identification Number and Backup Withholding. Federal income tax law of the United States requires that a holder of Old Notes whose Old Notes are accepted for exchange provide the Company with his correct taxpayer identification number, which, in the case of a holder who is an individual, is his or her social security number, or otherwise establish an exemption from backup withholding. If the Company is not provided with the correct taxpayer identification number, the exchanging holder of Old Notes may be subject to a $50 penalty imposed by the Internal Revenue Service (the "IRS"). In addition, interest on the Exchange Notes acquired pursuant to the Exchange Offer may be subject to backup withholding in an amount equal to 31% of any interest payment. If withholding occurs and results in an overpayment of taxes, a refund may be obtained. To prevent backup withholding, each exchange holder of Old Notes subject to backup withholding must provide his correct taxpayer identification number by completing the Substitute Form W-9 provided in this Letter of Transmittal, certifying that the taxpayer identification number provided is correct (or that the exchanging holder of Old Notes is awaiting a taxpayer identification number) and that either (a) the exchanging holder has not yet notified by the IRS that such holder is subject to backup withholding as a result of failure to report all interest or dividends or (b) the IRS has notified the exchanging holder that such holder is no longer subject to backup withholding. Certain exchanging holders of Old Notes (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding requirements. A foreign individual and other exempt holders (i.e. corporations) should certify, in accordance with the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9," to such exempt status on the Substitute Form W-9 provided in this Letter of Transmittal. 6. Transfer Taxes. Holders tendering pursuant to the Exchange Offer will not be obligated to pay brokerage commissions or fees or to pay transfer taxes with respect to their exchange under the Exchange Offer unless the box entitled "Special Issuance Instructions" in this Letter of Transmittal has been completed, or unless the Exchange Notes are to be issued to any person other than the holder of the Old Notes tendered for exchange. The Company will pay all other charges or expenses in connection with the Exchange Offer. If holders tender Old Notes for exchange and the Exchange Offer is not consummated, certificates representing the Old Notes will be returned to the holders at the Company's expense. Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the certificate(s) specified in this Letter of Transmittal. 7. Inadequate Space. If the space provided herein is inadequate, the aggregate principal amount of the Old Notes being tendered and the certificate numbers (if available) should be listed on a separate schedule attached hereto and separately signed by all parties required to sign this Letter of Transmittal. 8. Partial Tenders. Tenders of Old Notes will be accepted only in integral multiples of $1,000. If tenders are to be made with respect to less than the entire principal amount of any Old Notes, fill in the principal amount of Old Notes which are tendered in column (3) in the box on the cover entitled "Description of Old Notes Tendered." In the case of partial tenders, new certificates representing the Old Notes in fully registered form for the remainder of the principal amount of the Old Notes will be sent to the person(s) signing this Letter of Transmittal, unless otherwise indicated in the appropriate place on this Letter of Transmittal, as promptly as practicable after the expiration or termination of the Exchange Offer. 9. Mutilated, Lost, Stolen or Destroyed Old Notes. Any holder whose Old Notes have been mutilated, lost, stolen or destroyed should contact the Exchange Agent at the address indicated above for further instructions. 10. Request for Assistance or Additional Copies. Requests for assistance or additional copies of the Prospectus or this Letter of Transmittal may be obtained from the Exchange Agent at its telephone number set forth on the cover. 11 PAYER'S NAME: STATE STREET BANK AND TRUST COMPANY - ------------------------ -------------------------- -------------------------- SUBSTITUTE Part I--PLEASE PROVIDE Form W-9 YOUR TIN IN THE BOX AT -------------------------- Department of the RIGHT AND CERTIFY BY Social Security Number Treasury Internal SIGNING AND DATING BELOW.

Ltda., a Peruvian company ("Doe Run Mining"), and Doe Run Peru S.R. Ltda., a Peruvian company ("Doe Run Peru"), (collectively, the "Issuers") in connection with the preparation of the Issuers' Registration Statement on Form S-4 pursuant to the Securities Act of 1933, as amended (the "Securities Act"), being filed with the Securities and Exchange Commission (the "Commission") on the date hereof and to which this opinion letter is an exhibit. The Registration Statement relates to Doe Run's offer to exchange its 11 1/4% Senior Notes due 2005, Series B and Floating Interest Rate Senior Notes due 2003, Series B (collectively, the "Exchange Notes") for any and all of its outstanding 11 1/4% Senior Notes due 2005, Series A and Floating Interest Rate Senior Notes due 2003, Series A (collectively, the "Old Notes"), respectively. The Old Notes were issued, and the Exchange Notes are to be issued, under an indenture, dated as of March 12, 1998 (the "Indenture"), by and among Doe Run, as issuer, and FPI, Doe Run Cayman, Doe Run Mining and Doe Run Peru, as guarantors (collectively, in such capacity, the "Guarantors"), and State Street Bank and Trust Company, as trustee. In rendering the opinions expressed below, we have examined and relied upon, among other things, (a) the Registration Statement, including the Prospectus constituting a part thereof, (b) the Indenture filed as an exhibit to the Registration Statement and (c) originals or copies, certified or otherwise identified to our satisfaction, of such certificates, corporate, public or other records, and other documents as we have deemed appropriate for the purpose of rendering this opinion letter.

We have also made such investigations of law as we have deemed appropriate. In addition, we have assumed that the Exchange Notes and the guarantees of the Guarantors (the "Guarantees") will be executed and delivered in substantially the form in which they are filed as exhibits to the Registration Statement. Based upon the foregoing and subject to the qualifications set forth herein, we are of the opinion that: 1. The Exchange Notes and the Guarantees will be legally and validly issued and binding obligations of Doe Run and the Guarantors, as the case may be, (except to the extent enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other similar laws affecting the enforcement of creditors' rights generally and by the effect of general principles of equity, regardless of whether enforceability is considered in a proceeding in equity or at law), when the Registration Statement, as finally amended, shall have become effective under the Securities Act and the Indenture shall have been qualified under the Trust Indenture Act of 1939, as amended, (b) [the Issuers' respective board of directors or partners, as the case may be, have duly adopted final resolutions authorizing the issuance of the Notes and the Guarantees, as the case may be, as contemplated by the Registration Statement and the Indenture and (c)] the Exchange Notes shall have been duly executed, authenticated and delivered, and the Guarantees shall have been duly executed and delivered, as contemplated in the Registration Statement. 2. The statements made in the Prospectus constituting a part of the Registration Statement under the caption "Certain U.S. Federal Income Tax Considerations," insofar as such statements purport to summarize certain federal income tax laws of the United States of America, constitute a fair summary of the principal federal income tax consequences of an investment in the Exchange Notes.

The Employee shall be entitled to a travel expense advance in the discretion of the Company when anticipated travel warrants such advance. 5. Early Termination of Employment Term on Disability or Death. (a) If during the Employment Term, the Employee fails because of illness or other incapacity (including incapacity because of substance abuse) to render to the Company the services required of him hereunder for a period of two months (during which 3 the Company shall continue the Employee's compensation at the rates herein provided), the Company may, in its discretion, give one month notice of termination of the Employment Term (during which the Employee's compensation shall likewise be continued), and if the Employee shall not resume full performance of his duties within such one month period, the Employment Term shall terminate at the expiration thereof, provided that any such termination shall not affect the right of the Employee (or his estate) to continue to receive benefits under any disability insurance plan covering the Employee which is in effect at the date of termination, and further provided that if any such termination shall be during a fiscal year and the Company shall not have a net loss before income taxes determined as provided in paragraph 2(b) for such fiscal year, the Employee shall be entitled to a pro-rata portion of the minimum bonus for such year based on the number of full months worked by him in such year. (a) The Employment Term shall end upon the death of the Employee, provided that (i) if the Employee shall die during a fiscal year, and the Company shall not have a net loss, determined as provided in paragraph 2(b), for such fiscal year, the Employee shall be entitled to a pro-rata portion of the minimum bonus for such year, based on the number of full months worked by him during such year. 6.

For some years, the Employee has been a senior officer of the Company or a predecessor. He acknowledges that he has in the past had, and will continue to have, access to and knowledge of Company Confidential Information, and that improper use or revelation of same by the Employee during or after the termination of his employment by the Company could cause serious injury to the business of the Company. Accordingly, the Employee agrees that he will forever keep secret and inviolate all Company Confidential Information which shall have come or shall hereafter come into his possession, and that he will not use the same for his own private benefit, or directly or indirectly for the benefit of others, and that he will not disclose such Company Confidential Information to any other person. (b) Dring the Employment Term, the Employee will not (whether as an officer, director, partner, proprietor, investor, associate, employee, consultant, adviser, public relations or advertising representative or otherwise), directly or indirectly, be engaged in any aspect of the business of lead mining, milling, recycling or sale within the continental United States (which the parties acknowledge is the Company's trading area). For purposes of the preceding sentence, the Employee shall be deemed to be engaged in any business which any person for whom he shall perform services is engaged. Nothing herein contained 5 shall be deemed to prohibit the Employee from owning, as a passive investment, a security of any issuer which is not a supplier, vendor; customer or competitor of the Company. (c) Within the terms of this Agreement, it is intended to limit disclosure and competition by the Employee to the maximum extent permitted by law. If it shall be finally determined by any court of competent jurisdiction ruling on this Agreement that the scope or duration of any limitation contained in this paragraph 7 is too extensive to be legally enforceable, then the parties hereby agree that the scope and duration (not greater than that provided for herein) of such limitation shall be the maximum scope and duration which shall be legally enforceable and the Employee hereby consents to the enforcement of such limitation as so modified. (d) The Employee acknowledges that any violation by him of the provisions of this paragraph 7 could cause serious and irreparable damages to the Company. He further acknowledges that it might hot be possible to measure such-damages in money.

Employee's Inventions. The Employee agrees to assign and transfer to the Company, its successors and assigns, his entire right, title and interest in and to any or all inventions, designs, discoveries and improvements which he may make, either solely or jointly with others, 6 during the Employment Term hereunder and for a period of one (1) year thereafter, which relate in any way to the business or products of the Company, together with all rights to letters patent which may be granted thereon.

The Company shall pay all expenses involved in carrying out the provisions of this paragraph 8. 9. Benefits. The Company agrees to provide to the Employee during the Employment Term the medical, hospitalization, disability insurance benefits and other benefits as it provides to its other senior officers. 10. Employee's Representation. Employee hereby represents to the Company that he has full right and power to enter into this Agreement and carry out his duties hereunder, and that same will not constitute a breach of or default under any employment, confidentiality, non-competition or other agreement by which he may be bound. 7 11. Default by Employee. If the Employee shall: (i) commit an act of dishonesty against the Company or fraud upon the Company; or (ii) breach his obligations under-this Agreement and fail to cure such breach within five (5) days after written notice thereof; or (iii) be convicted of a crime involving moral turpitude; or (iv) fail or neglect diligently to perform his duties hereunder and continue in his failure after written notice; then, and in any such case, the Company may terminate the employment of the Employee hereunder and, in the event of any such termination, the Employee shall no longer have any right to any and all benefits (including future salary payments) which would otherwise have accrued after such termination. 12.

Zelms c/o The Doe Run Resources Corporation 1801 Park 270 Drive St. Louis, Missouri 63146 Re: Net Worth Appreciation Agreement -------------------------------- Dear Mr. Zelms: This will confirm the understanding of this corporation, (the "Company") with you, effective upon acquisition by this corporation of the capital stock of The Doe Run Resources Corporation ("Doe Run"), with respect to your Net Worth Appreciation benefit, intended to constitute additional incentive compensation to you as an employee of Doe Run. 1. Vesting. On March 31, 1997, provided that you have been continuously in the employ of Doe Run from the date hereof through that date, you shall receive a net worth appreciation credit of 3% and on March 31 in each of the years 1998 and 1999 you shall receive an additional net worth appreciation credit of -2- 1%, provided that you have been continuously in the employ of Doe Run from the date hereof to the applicable March 31, for a maximum credit, if you remain in the employ of Doe Run continuously through March 31, 1999, of 5%. You shall not receive any credit unless you remain in the employ of Doe Run from the date hereof continually until March 31, 1997, and thereafter you shall not receive credit for any partial year, provided that (a) if your employment terminates due to death or permanent disability preventing you from performing your usual employment functions and duties ("disability") on or after March 31, 1995 and prior to March 31, 1997, you shall receive a credit of 1% if such termination is prior to March 31, 1996 and 2% if such termination is on or after March 31, 1996 and prior to March 31, 1997, and (b) if your employment terminates after March 31, 1997 and before March 31, 1999, due to death or disability, you shall receive a credit of 1% for the partial year in which the termination takes place (in addition to all credits previously accrued). -3- 2. Net Worth Appreciation Benefit. Upon the termination of your employment by Doe Run, other than for cause, you shall be entitled to a net worth appreciation payment ("Payment") equal to the product of (a) the total percentage credited to you under paragraph 1 (a maximum of 5%) multiplied by (b) the "net worth increment." The "net worth increment" is the amount, if any, by which the consolidated net worth of this Company and its subsidiaries, as at the end of its fiscal quarter immediately preceding the date of your termination, exceeds its consolidated net worth as of the date hereof, provided, however, that any increase in net worth resulting from a capital contribution to the Company or Doe Run or the sale of stock of the Company or Doe Run shall be disregarded in calculating "net worth increment". The determination of the independent public accountants for the Company as to the net worth increment, made in accordance with generally accepted accounting principles, consistently applied, shall be conclusive on each of us. If there is no "net worth increment", no amount shall be payable. If your employment is terminated for legal cause, you shall not be entitled to receive any payment. -4- 3. Payment. The Payment shall be payable to you (or your designee or estate) in 40 equal quarterly installments, without interest, commencing three (3) months after the termination of your employment, and at 3 month intervals thereafter. 4.

(a) If and in the event either Doe Run or the Company shall pay either a dividend or management fee or any other form of distribution in excess of $1,200,000 annually to The Renco Group, Inc. ("Renco") or any affiliate, other than a subsidiary of the Company, (this distribution shall include any transfer of assets from the Company or Doe Run to Renco or any other subsidiary company of Renco in any form whether as cash or other form of value which shall have the effect of reducing the net worth of the Company) while you shall be employed by Doe Run, then you shall be entitled to receive, as additional compensation, an amount equal to 5% of such cash dividend or distribution. This provision shall not -5- apply to intercompany payments among the Company and its own wholly-owned subsidiaries or among two wholly-owned subsidiaries of the Company, or to reimbursement to Renco for a proportionate part of costs, such as audit charges and insurance premiums, paid by Renco on behalf of itself and all of its subsidiaries including the Company and Doe Run; (b) If, while you shall be employed by Doe Run (and whether before or after March 31, 1997), all or substantially all the stock or assets of the Company or of Doe Run shall be sold to a person who is not an affiliate of Ira Leon Rennert, or if The Renco Group, Inc. sells a controlling interest in the Company, then, upon the closing of such sale, your full 5% net worth appreciation credit shall be deemed to be vested, and you shall be entitled to receive as payment in full of your participation, your pro rata share (5%) of the "net proceeds" of the sale, in kind, on the same terms and conditions as the Company or its shareholder is being paid. "Net proceeds", for purposes hereof, shall mean the amount if any, by which the proceeds -6- of the sale after deducting all expenses of the sale, all applicable federal, state and local taxes, and all liabilities retained by the seller exceeds the consolidated net worth of the Company on the date hereof. Except for such payment, neither you nor this Company nor Doe Run have any further rights or liabilities hereunder. 5. Condition Precedent. The Company's obligation to make the Payment to you shall be conditioned on your faithful adherence to your employment arrangements with Doe Run and on your refraining from engaging directly or indirectly in any activity competitive with the business of the Company or Doe Run during the period over which such payments are to be made to you. If you do engage in any such competitive activities, then we shall no longer be obligated to make any payments to you hereunder. 6. Notice.

Amistadi c/o The Doe Run Resources Corporation 1801 Park 270 Drive St. Louis, Missouri 63146 Re: Net Worth Appreciation Agreement -------------------------------- Dear Mr. Amistadi: This will confirm the understanding of this corporation, (the "Company") with you, effective upon acquisition by this corporation of the capital stock of The Doe Run Resources Corporation ("Doe Run"), with respect to your Net Worth Appreciation benefit, intended to constitute additional incentive compensation to you as an employee of Doe Run. 1. VESTING. On March 31, 1997, provided that you have been continuously in the employ of Doe Run from the date hereof through that date, you shall receive a net worth appreciation credit of 9/10ths of 1% and on March 31 in each of the years 1998 and 1999 you shall receive an additional net worth appreciation -2- credit of 3/10th of 1%, provided that you have been continuously in the employ of Doe Run from the date hereof to the applicable March 31, for a maximum credit, if you remain in the employ of Doe Run continuously through March 31, 1999, of 1.5%. You shall not receive any credit unless you remain in the employ of Doe Run from the date hereof continually until March 31, 1997, and thereafter you shall not receive credit for any partial year, provided that (a) if your employment terminates due to death or permanent disability preventing you from performing your usual employment functions and duties ("disability") on or after March 31, 1995 and prior to March 31, 1997, you shall receive a credit of 3/10th of 1% if such termination is prior to March 31, 1996 and 6/10ths of 1% if such termination is on or after March 31, 1996 and prior to March 31, 1997, and (b) if your employment terminates after March 31, 1997 and before March 31, 1999, due to death or disability, you shall receive a credit of 3/10th of 1% for the partial year in which the termination takes place (in addition to all credits previously accrued). -3- 2. NET WORTH APPRECIATION BENEFIT. Upon the termination of your employment by Doe Run, other than for cause, you shall be entitled to a net worth appreciation payment ("Payment") equal to the product of (a) the total percentage credited to you under paragraph 1 (a maximum of 1.5%) multiplied by (b) the "net worth increment." The "net worth increment" is the amount, if any, by which the consolidated net worth of this Company and its subsidiaries, as at the end of its fiscal quarter immediately preceding the date of your termination, exceeds its consolidated net worth as of the date hereof, provided, however, that any increase in net worth resulting from a capital contribution to the Company or Doe Run or the sale of stock of the Company or Doe Run shall be disregarded in calculating "net worth increment". The determination of the independent public accountants for the Company as to the net worth increment, made in accordance with generally accepted accounting principles, consistently applied, shall be conclusive on each of us. If there is no "net worth increment", no amount shall be payable. If your employment is terminated for legal cause, you shall not be entitled to receive any payment. -4- 3. PAYMENT. The Payment shall be payable to you (or your designee or estate) in 40 equal quarterly installments, without interest, commencing three (3) months after the termination of your employment, and at 3 month intervals thereafter. 4. DIVIDENDS; SALE OF SUBSTANTIALLY ALL OF THE COMPANY'S STOCK OR ASSETS. (a) If and in the event either Doe Run or the Company shall pay either a dividend or management fee or any other form of distribution in excess of $1,200,000 annually to The Renco Group, Inc. ("Renco") or any affiliate, other than a subsidiary of the Company, (this distribution shall include any transfer of assets from the Company or Doe Run to Renco or any other subsidiary company of Renco in any form whether as cash or other form of value which shall have the effect of reducing the net worth of the Company) while you shall be employed by Doe Run, then you shall be entitled to receive, as additional compensation, an amount equal to 1.5% of such cash dividend or distribution. This provision shall not -5- apply to intercompany payments among the Company and its own wholly-owned subsidiaries or among two wholly-owned subsidiaries of the Company, or to reimbursement to Renco for a proportionate part of costs, such as audit charges and insurance premiums, paid by Renco on behalf of itself and all of its subsidiaries including the Company and Doe Run; (b) If, while you shall be employed by Doe Run (and whether before or after March 31, 1997), all or substantially all the stock or assets of the Company or of Doe Run shall be sold to a person who is not an affiliate of Ira Leon Rennert, or if The Renco Group, Inc. sells a controlling interest in the Company, then, upon the closing of such sale, your full 1.5% net worth appreciation credit shall be deemed to be vested, and you shall be entitled to receive as payment in full of your participation, your pro rata share (1.5%) of the "net proceeds" of the sale, in kind, on the same terms and conditions as the Company or its shareholder is being paid. "Net proceeds", for purposes hereof, shall mean the amount if any, by which the proceeds -6- of the sale after deducting all expenses of the sale, all applicable federal, state and local taxes, and all liabilities retained by the seller exceeds the consolidated net worth of the Company on the date hereof. Except for such payment, neither you nor this Company nor Doe Run have any further rights or liabilities hereunder. 5. CONDITION PRECEDENT. The Company's obligation to make the Payment to you shall be conditioned on your faithful adherence to your employment arrangements with Doe Run and on your refraining from engaging directly or indirectly in any activity competitive with the business of the Company or Doe Run during the period over which such payments are to be made to you. If you do engage in any such competitive activities, then we shall no longer be obligated to make any payments to you hereunder. 6. NOTICE.

Zelms Internal THE DOE RUN COMPANY Suite 300 Correspondence 1801 Park 270 Drive St. Louis, MO 63146 CONFIDENTIAL CONFIDENTIAL TO: J. L. Zelms DATE: September 30, 1996 FROM: J.E. Stack SUBJ: Supplemental Employee Retirement Plan ("SERP") The total compensation program of The Doe Run Company has been significantly altered over the past years by government action that has resulted in reduction of retirement benefits for a few higher-compensated executive employees. The reductions have occurred due to the application of IRS Code Section 415 and/or IRS Code Section 401(a)(17). The above actions have severely impacted certain employees. I recommend the adoption of a program (SERP) which would make up the retirement benefits that are capped or reduced from the level that would otherwise have been realized under our retirement program. This program would be in the form of a non-qualified plan which would be an unfunded liability of the Company requiring the Company to make up from its general assets any reduction that an affected employee might experience due to the retirement benefit caps. The Company would be required under FASB 87 to record this liability as an expense but the Company would not experience any cash impact until benefits are paid. Based on January 1, 1996 employee census data as calculated by Buck Consultants, our pension actuary, the net periodic cost of such plan for the first year is estimated at $185,000. My recommendation is based on the following employee-relations issues and in consideration of the above-mentioned costs: - Our retirement program now discriminates against a few higher-paid employees in limiting retirement benefits, not by Company design but due to regulatory actions. - The reductions have amounted to a "take-away" in that the benefits have been reduced by regulation after having been higher by plan design. - It is very important to Doe Run to attract and retain management personnel over a long-term relationship due to the cyclicality of our industry and the commodity pricing structure in which we compete. - The recorded liability as a FASB 87 expense is approximately one-half of one percent of our total annual compensation costs.

In determining eligibility, Lender may, but need not, rely on agings, reports and schedules of Accounts furnished to Lender by such Borrower, but reliance by Lender thereon from time to time shall not be deemed to limit Lender's right to revise standards of eligibility at any time as to both present and future Accounts.

or (j) the sale to the Account Debtor is on a bill-and-hold guaranteed sale (except as otherwise provided below), sale-and-return, ship-and-return, sale on approval or consignment or other similar basis or made pursuant to any other written agreement providing for repurchase or return of any merchandise which has been claimed to be defective or otherwise unsatisfactory; or (k) the Account Debtor is any Governmental Authority; or (l) the goods giving rise to such Account have not been shipped and delivered to the Account Debtor, or the Account otherwise does not represent a final sale (subject only to the Account Debtor's right to reject non-conforming goods) except that if the goods giving rise to such Account have not been shipped and delivered to the Account Debtor, if Lender shall have received a written agreement, in form and substance satisfactory to Lender, evidencing the Account Debtor's unconditional obligation to take and pay for such goods; or (m) the Account does not comply with all applicable law; or (n) (i) either the perfection, enforceability or validity of Lender's security interest or Lender's right or ability to receive direct payments as to such Account is governed by any statutory requirement of any Governmental Authority other than those of the Uniform Commercial Code, (ii) the Account Debtor has not waived counterclaims or setoffs as to such Account, (iii) it is not subject to a valid and perfected first priority security interest, lien or other encumbrance in favor of the Lender, subject to no security interest, liens or other encumbrances other than the security interests, liens or other encumbrances (if any) permitted hereunder or (iv) it does not otherwise conform to the representations and warranties contained herein or in the other Financing Agreements;

Standards of eligibility may be fixed and revised from time to time solely by Lender in its exclusive judgment. In determining eligibility Lender may, but need not, rely on reports and schedules of such Inventory furnished to Lender by such Borrower, but reliance thereon by Lender from time to time shall not be deemed to limit Lender's right to revise standards of eligibility at any time. In general, except in Lender's discretion, Inventory shall not be deemed Eligible Inventory if: (a) it is not owned solely by such Borrower or such Borrower does not have sole and good, valid and marketable title thereto; or (b) it is not either (i) located in the continental United States or (ii) loaded, freight charges and insurance premiums paid, upon a vessel bound for a port in the continental United States and covered by bills of lading or other shipping documents, originals of which are in the possession of Lender; or (c) it is not located at premises owned and operated by such Borrower or it is on consignment to a third party, provided, that, any Inventory which would otherwise be deemed Eligible Inventory at locations which are not owned and operated by such Borrower may nevertheless be considered Eligible Inventory: (i) if Lender shall have received a Collateral Access Agreement from the holder of such Inventory or the owner and/or operator of such location, as the case may be, and (ii) in addition to the agreement described above, if the Inventory is delivered to the holder, owner and/or operator on consignment and if required by Lender: (A) the holder, owner and/or operator executes appropriate UCC-1 financing statements in favor of such Borrower, which are duly assigned to Lender and (B) any lender to the holder, owner and/or operator with any interest in Inventory is properly notified of the first priority security interest in and lien on such Inventory of Lender; or (d) it is packing or shipping materials or maintenance supplies; or (e) it is not subject to a valid and perfected first priority security interest and Lender, except, with respect to Inventory stored at sites described in clause (c) above, for liens for unpaid rent or normal and customary warehousing charges, in each case, not yet due; or (f) it is goods returned or rejected by such Borrower's customers or goods in transit to third parties (other than to warehouse sites covered by a Collateral Access Agreement); or (g) it (i) is prepaid or (ii) is excess (as so reserved by such Borrower from time to time or as otherwise determined by Lender) or (iii) is seconds or thirds or (iv) is obsolete, slow moving or unmerchantable, or (v) is freight/drayage reserves, or (vi) is samples or Inventory on -9- hand which is used for promotional and other sales activities, or (vii) does not otherwise conform to the representations and warranties contained in the credit documents; or (h) is used or repossessed, or is attached, seized, made subject to a writ or distress warrant, levied upon or brought within the possession of any receiver, trustee, custodian or assignee for the benefit of creditors; or (i) it is obsolete, defective, damaged or unmerchantable; or (j) it is goods acquired by such Borrower in or as part of a "bulk" transfer or sale of assets and such acquisition is not consummated in the ordinary course of business unless such Borrower has complied with all applicable bulk sales or bulk transfer laws in connection with such acquisition; or (k) it is unmined ore or otherwise constitutes real property; or (l) Lender in the exercise of its good faith judgment determines it to be ineligible.

Any rights, remedies, duties or obligations undertaken by Lender to any issuer or correspondent in any application for any Letter of Credit Accommodation, or any other agreement by Lender in favor of any issuer or correspondent relating to any Letter of Credit Accommodation, shall be deemed to have been granted or undertaken by the Borrower requesting such Letter of Credit Accommodation to Lender and to apply in all respects to such Borrower. 2.3. Maximum Credit. Except in Lender's discretion, the aggregate amount of the Loans and the Letter of Credit Accommodations outstanding at any time shall not exceed the Maximum Credit. 2.4. Reserves. Without limiting any other rights and remedies of Lender hereunder or under the other Financing Agreements, all Loans otherwise available to Borrowers shall be subject to Lender's continuing right in its discretion, to establish a reserve reducing the amounts of Loans otherwise available to Borrowers and to increase and decrease such reserve from time to time, if and to the extent that, in Lender's judgment, such reserve is necessary to protect Lender against possible non-payment for any reason by Account Debtors or possible non-payment of any of the Obligations, or in respect of any state of facts which does or would, -23- with notice or passage of time or both, constitute an Event of Default hereunder or for any other reason. 2.5 Mandatory Prepayments (a) In the event that the outstanding amount of the Loans to Borrowers exceed the Borrowing Base, or any component of the Loans exceed the sublimits set forth in Section 2.1(b), or the aggregate amount of the outstanding Letter of Credit Accommodations exceed the sublimit for Letter of Credit Accommodations set forth in Section 2.2(d), or the aggregate amount of the Loans and the Letter of Credit Accommodations outstanding at any time shall exceed the Maximum Credit, such event shall not limit, waive or otherwise affect any rights of Lender in that circumstance or on any future occasions and Borrowers shall, upon demand by Lender, which may be made at any time or from time to time, immediately repay to Lender, the entire amount of any such excess(es) for which payment is demanded.

In the event that a court determines that Lender has received interest and other charges hereunder in excess of the highest rate applicable hereto, such excess shall be deemed received on account of, and shall automatically be applied to reduce, the Obligations other than interest in the inverse order of maturity, and the provisions hereof shall be deemed amended to provide for the highest permissible rate. (c) Subject to the foregoing, all interest charges hereunder or in connection herewith shall be (i) computed as provided herein and in the other Financing Agreements and (ii) paid monthly to Lender on the first day of each calendar month, or, at Lender's option, charged to a Borrower's account(s) maintained by Lender as of the first day of each calendar month and deemed paid by the first amounts subsequently credited thereto.

Borrowers shall be liable for all amounts due to Lender under this Agreement, regardless of which Borrower actually receives the Loans or other extensions of credit hereunder or the amount of such Loans received or the manner in which Lender accounts for such Loans, Letter of Credit Accommodations or other extensions of credit on its books and records. The Obligations with respect to Loans made to a Borrower, and the Obligations arising as a result of the joint and several liability of a Borrower hereunder, with respect to Loans made to the other Borrower hereunder, shall be separate and distinct obligations, but all such other Obligations shall be primary obligations of both Borrowers. The Obligations arising as a result of the joint and several liability of a Borrower hereunder with respect to Loans, Letter of Credit Accommodations or other extensions of credit made to the other Borrower hereunder shall, to the fullest extent permitted by law, be unconditional irrespective of (a) the validity or enforceability, avoidance or subordination of the Obligations of the other Borrower or of any promissory note or other document evidencing all or any part of the Obligations of the other Borrower, (b) the absence of any attempt to collect the Obligations from the other Borrower or any other security therefor, or the absence of any other action to enforce the same, (c) the waiver, consent, extension, forbearance or granting of any indulgence by Lender with respect to any provisions of any instrument evidencing the Obligations of the other Borrower, or any part thereof, or any other agreement now or hereafter executed by the other Borrower and delivered to Lender, (d) the failure by Lender to take any steps to perfect and maintain its security interest in, or to preserve its rights and maintain its security or collateral for the Obligations of the other Borrower, (e) the election of Lender in any proceeding instituted under the Bankruptcy Code, of the application of Section 1111(b)(2) of the Bankruptcy Code, (f) any borrowings or grant or a security interest by the other Borrower, as debtor-in-possession under Section 364 of the Bankruptcy Code, (g) the disallowance of all or any portion of the claim(s) of Lender for the repayment of the Obligations of the other Borrower under Section 502 of the Bankruptcy Code, or (h) any other circumstances which might constitute a legal or equitable discharge or defense of a guarantor or of the other Borrower. With respect to the Obligations arising as a result of the joint and several liability of a Borrower hereunder with respect to Loans, Letter of Credit Accommodations or other extensions of credit made to the other Borrower hereunder, each Borrower waives, until the Obligations shall have been paid in full and this Agreement shall have been terminated, any right to enforce any right of subrogation or any remedy which Lender now has or may hereafter have against Borrowers, any endorser or any guarantor of all or any part of the Obligations, and any benefit of, and any right to participate in, any security or collateral given to Lender. Upon any Event of Default, Lender may proceed directly and at once, without notice (except as otherwise specifically provided for herein), against either Borrower to collect and recover the full amount, or any portion of the Obligations, without first proceeding against the other Borrower or any other Person, or against any security or collateral for the Obligations. Each Borrower consents and agrees that Lender shall be under no obligation to marshall any assets in favor of Borrower(s) or against or in payment of any or all of the Obligations. -26- SECTION 3.

(a) Without limiting Lender's rights to demand payment sooner as provided in this Agreement, upon or at any time after the occurrence or existence of any one or more of such Events of Default, upon termination of this Agreement or the other Financing Agreements, or if this Agreement and the other Financing Agreements are not renewed, in addition to any other rights Lender may have under the Financing Agreements or otherwise: (i) Lender may terminate all provisions of this Agreement for future Loans and Letter of Credit Accommodations (such that no more Loans shall be made or Letter of Credit Accommodations provided hereunder), without presentment for payment, demand, notice of dishonor or notice of protest or any other or further notice, all of which are hereby expressly waived by Borrowers; or (ii) Lender may declare any or all of the Obligations to be immediately due and payable, together with interest at the highest rate of interest hereunder until fully and indefeasibly paid, without presentment for payment, demand, notice of dishonor or protest or any -69- or other further notice, all of which are hereby expressly waived by Borrowers (provided, that, upon the occurrence of any Events of Default described in Sections 7.1(f) or 7.1(g), all Obligations shall automatically become immediately due and payable); and (iii) each Participant, to the fullest extent permitted by applicable law, shall have the right to (A) set off against the Obligations any and all deposits (whether general or special, time or demand, provisional or final), credits, balances, accounts, monies or other assets which are the property of Borrowers and held by such Participant or owed by such Participant to such Borrower and (B) remit the same to Lender for application to the Obligations; (iv) without further notice to Borrowers, Lender may appropriate, set off and apply to the payment of any or all of the Obligations, any or all Collateral, in such manner as Lender shall determine, enforce payment of any Collateral, settle, compromise or release in whole or in part, any amounts owing on the Collateral, make allowances and adjustments with respect thereto, issue credits in Lender's or either Borrower's name, sell, assign and deliver the Collateral (or any part thereof), at public or private sale, at broker's board, for cash, upon credit or otherwise, at Lender's option and discretion, and Lender may bid or become purchaser at any such sale, if public, free from any right of redemption which is hereby expressly waived; (v) without limiting the generality of the foregoing, Lender is hereby authorized at any time and from time to time, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Indebtedness at any time owing by Lender to or for the credit or the account of Borrowers against any and all of the Obligations, whether or not then due and payable; (vi) Lender shall have the right, without notice to Borrowers (except as otherwise expressly provided herein), at any time and from time to time in its discretion, with or without judicial process or the aid or assistance of others and without cost to Lender (A) to enter upon any premises on or in which any of the Inventory may be located and, without resistance or interference by Borrowers, take possession of the Inventory, (B) to complete processing, manufacturing and repair of all or any portion of the Inventory, (C) to sell, foreclose or otherwise dispose of any part or all of the Inventory on or in any premises of Borrower or premises of any other party, (D) to require each Borrower, at its expense, to assemble and make available to Lender any part or all of the Inventory at any reasonable place and time designated by Lender, and (E) to remove any or all of the Inventory from any premises on or in which the same may be located, for the purpose of effecting the sale, foreclosure or other disposition thereof or for any other purpose. (b) Lender shall have all of the rights and remedies of a secured party under the UCC or applicable law of any State in which any Collateral may be situated, in addition to all of the rights and remedies set forth in this Agreement and the other Financing Agreements, and in -70- any instrument or document referred to herein or therein, and/or under any other applicable law relating to this Agreement, the other Financing Agreements, the Obligations or the Collateral. (c) Each Borrower agrees that the giving of ten (10) days notice to Doe Run by Lender at Doe Run's address set forth below, designating the place and time of any public sale or of the time after which any private sale or other intended disposition of the Collateral is to be made, shall be deemed to be reasonable notice thereof and each Borrower waives any other notice with respect thereto. (d) The proceeds resulting from the exercise of any of the foregoing rights or remedies shall be applied by Lender to the payment of the Obligations in such order as Lender may elect, and each Borrower shall remain liable to Lender for any deficiency. Without limiting the generality of the foregoing, if Lender enters into any credit transaction, directly or indirectly, in connection with the disposition of any Collateral, it shall have the option, at any time, in its discretion, to reduce the Obligations by the principal amount of such credit transaction or to defer the reduction thereof until actual receipt by Lender of cash or other immediately available funds in connection therewith. (e) In the event Lender institutes an action to recover any Collateral or seeks recovery of any Collateral by way of prejudgment remedy or otherwise, each Borrower hereby irrevocably waives (i) the posting of any bond, surety or security with respect thereto which might otherwise be required, (ii) any demand for possession prior to the commencement of any suit or action to recover the Collateral, and (iii) any requirement that Lender retain possession and not dispose of any Collateral until after trial or final judgment. (f) Lender may, at its option, cure any default by a Borrower under any agreement with any Person, which constitutes, or with notice or passage of time or both would constitute, an Event of Default hereunder or under any of the other Financing Agreements, or pay or bond on appeal any judgment entered against a Borrower (irrespective of the amount of said judgment or the time elapsed since entry thereof), and charge such Borrower's account(s) therefor, such amounts to be repayable by such Borrower on demand, together with interest thereon at the highest rate of interest payable hereunder; provided, however, Lender shall be under no obligation to effect such cure, payment or bonding and shall not, by making any payment for such Borrower's account(s), be deemed to have assumed any obligation or liability of such Borrower. (g) The enumeration of the foregoing rights and remedies is not intended to be exclusive, and such rights and remedies are in addition to and not by way of limitation of any other rights or remedies Lender may have under the UCC or other applicable law. Lender shall have the right to determine which rights and remedies, and in which order any of the same, are to be exercised, and to determine which Collateral is to be proceeded against and in which order, -71- and the exercise of any right or remedy shall not preclude the exercise of any others, all of which shall be cumulative. (h) No act, failure or delay by Lender shall constitute a waiver of any of the rights and remedies of Lender. No single or partial waiver by Lender of any provision of this Agreement or any of the other Financing Agreements, or breach or default thereunder, or of any right or remedy which Lender may have shall operate as a waiver of any other provision, breach, default, right or remedy or of the same provision, breach, default, right or remedy on a future occasion. (i) Each Borrower waives presentment, notice of dishonor, protest and notice of protest of all instruments included in or evidencing any of the Obligations or the Collateral and any and all notices or demands whatsoever (except as expressly provided herein). Lender may, at all times, proceed directly against either or both of Borrowers to enforce payment of the Obligations and shall not be required to take any action of any kind to preserve, collect or protect any rights in the Collateral. SECTION 8. COLLECTION AND ADMINISTRATION 8.1 Collections; Management of Collateral. (a) Each Borrower shall establish and maintain, at its expense, blocked accounts or lockboxes and related blocked accounts (in either case, "Blocked Accounts"), as Lender may specify, with such banks as are acceptable to Lender into which such Borrower shall promptly deposit and direct its account debtors to directly remit all payments on Accounts and all payments constituting proceeds of Inventory or other Collateral in the identical form in which such payments are made, whether by cash, check or other manner. The banks at which the Blocked Accounts are established shall enter into an agreement, in form and substance satisfactory to Lender, providing that all items received or deposited in the Blocked Accounts are subject to the security interests and rights of Lender, that the depository bank has no lien upon, or right to setoff against, the Blocked Accounts, the items received for deposit therein, or the funds from time to time on deposit therein and that the depository bank will wire, or otherwise transfer, in immediately available funds, on a daily basis, at such time as Lender shall direct, all funds received or deposited into the Blocked Accounts to such bank account of Lender as Lender may from time to time designate for such purpose ("Payment Account"). Borrowers agree that all payments made to such Blocked Accounts or other funds received and collected by Lender, whether on the Accounts or as proceeds of Inventory or other Collateral or otherwise shall be subject to the security interests and rights of Lender. (b) For purposes of calculating interest on the Obligations, such payments or other funds received will be applied (conditional upon final collection) to the Obligations one (1) -72- Business Day following the date of receipt of immediately available funds by Lender in the Payment Account (the "Collection Period"). In the event that as of any day there are no Loans outstanding, Lender shall be entitled to charge Borrowers an administrative fee equivalent to the interest Lender would have received for the Collection Period had there been Loans outstanding on such day, in the amount of the payments and other funds received pursuant to the preceding sentence by Lender in the Payment Account on such day. For purposes of calculating the amount of the Loans available to each Borrower such payments will be applied (conditional upon final collection) to the Obligations on the Business Day of receipt by Lender in the Payment Account, if such payments are received within sufficient time (in accordance with Lender's usual and customary practices as in effect from time to time) to credit such Borrower's loan account on such day, and if not, then on the next Business Day. To the extent Lender may hold cash collateral to secure all of the Obligations on terms and conditions determined by Lender, so long as no Event of Default shall exist or have occurred and be continuing, the Borrower providing such cash collateral shall receive a credit to its loan account maintained by Lender at a rate equal to three (3%) percent per annum less than the Prime Rate. Such credit shall be applied to the loan account of such Borrower as of the first day of each month. (c) Each Borrower and all of its Subsidiaries, shareholders, directors, employees, agents and other Affiliates shall, acting as trustee for Lender, receive, as the property of Lender according to its interest hereunder, any monies, checks, notes, drafts or any other payment relating to and/or proceeds of Accounts or other Collateral which come into their possession or under their control and immediately upon receipt thereof, shall deposit or cause the same to be deposited in the Blocked Accounts, or remit the same or cause the same to be remitted, in kind, to Lender. In no event shall the same be commingled with such Borrower's own funds. Each Borrower agrees to reimburse Lender on demand for any amounts owed or paid to any bank at which a Blocked Account is established or any other bank or person involved in the transfer of funds to or from the Blocked Accounts arising out of Lender's payments to or indemnification of such bank or person. The obligation of Borrowers to reimburse Lender for such amounts pursuant to this Section 8.1 shall survive the termination or non-renewal of this Agreement. -73- 8.2 Payments. (a) All Obligations shall be payable to the Payment Account as designated under Section 8.1 or such other place as Lender may designate from time to time. The Obligations shall be payable upon the effective date of termination or non-renewal or maturity of the Credit Facility, or earlier upon an Event of Default, or otherwise as provided elsewhere herein or in the other Financing Agreements. Lender may apply payments received or collected from a Borrower or for the account of a Borrower (including, without limitation, the monetary proceeds of collections or of realization upon any Collateral) to such of the Obligations, whether or not then due, and to such other Obligations then due, in each case in such order and manner as Lender determines. Lender shall have the continuing and exclusive right to apply and reverse and reapply any and all such proceeds and payments to any portion of the Obligations. Upon the request of Lender, Borrowers shall execute and deliver to Lender one or more promissory notes, in form and substance satisfactory to Lender, to evidence further the Loans, or any portion thereof. (b) If after receipt of any payment of, or proceeds applied to the payment of, all or any part of the Obligations, Lender is for any reason required to surrender such payment or proceeds to any Person, because such payment or proceeds is invalidated, declared fraudulent, set aside, determined to be void or voidable as a preference, or a diversion of trust funds, or for any other reason, then the Obligations or any part thereof intended to be satisfied shall be revived and continue and this Agreement shall continue in full force as if such payment or proceeds had not been received by such Lender and Borrowers shall be liable to pay to Lender, and hereby does indemnify Lender and hold Lender harmless for the amount of such payment or proceeds surrendered. The provisions of this Section 8.2(b) shall be and remain effective notwithstanding any contrary action which may have been taken by Lender in reliance upon such payment or proceeds, and any such contrary action so taken shall be without prejudice to the rights of Lender under this Agreement and shall be deemed to have been conditioned upon such payment or proceeds having become final and irrevocable. The provisions of this Section 8.2(b) shall survive the termination of this Agreement and the other Financing Agreements. (c) At Lender's option, all principal, interest, fees, commissions, costs, expenses, or other charges hereunder, under the other Financing Agreements or in connection herewith or therewith, and any and all Loans, may be charged directly to any account(s) of Borrowers maintained by Lender. (d) Each Borrower shall make all payments in respect of the Obligations free and clear of, and without deduction or withholding for or on account of, any setoff, counterclaim, defense, duties, taxes, levies, imposts, fees, deductions, withholdings, restrictions or conditions of any kind or nature whatsoever. -74- 8.3 Borrowers' Loan Account. Lender shall maintain one or more loan account(s) on its books in which shall be recorded (a) all Loans, Letter of Credit Accommodations and other Obligations and the Collateral, (b) all payments made by or on behalf of a Borrower and (c) all other appropriate debits and credits as provided in this Agreement, including, without limitation, fees, charges, costs, expenses and interest. All entries in the loan account(s) shall be made in accordance with Lender's customary practices as in effect from time to time. All Collateral or other collateral security held by or granted to Lender by a Borrower or any third persons shall be security for the payment and performance of any and all Obligations to Lender (including, but not limited to, the Loans), notwithstanding the maintenance of separate accounts for Borrowers or third persons or the existence of any notes. 8.4 Statements. Lender shall render to Doe Run each month a statement setting forth the balance in each Borrower's loan account(s) maintained by Lender for such Borrower pursuant to the provisions of this Agreement, including principal, interest, fees, costs and expenses. Each such statement shall be subject to subsequent adjustment by Lender but shall, absent manifest errors or omissions, be considered correct and deemed accepted by Borrowers and conclusively binding upon Borrowers as an account stated except to the extent that Lender receives a written notice from Borrowers of any specific exceptions of Borrowers thereto within thirty (30) days after the date such statement has been mailed by Lender. Until such time as Lender shall have rendered to Doe Run a written statement as provided above, the balance in such Borrower's loan account(s) shall be presumptive evidence of the amounts due and owing by such Borrower to Lender. 8.5 Right of Inspection; Access. Lender and its representatives shall, at all reasonable times and upon reasonable prior written notice prior to an Event of Default and at any time and without notice at any time on or after an Event of Default, have free access to and right of inspection of the Collateral and have full access to and the right to examine and make copies of the books and records of Borrowers to confirm and verify all Accounts, to perform general audits and to do whatever else Lender deems necessary to protect the interests of Lender. Lender may at any time remove from the premises of Borrowers or require Borrower or any accountants and auditors employed by Borrowers to deliver any books and records and Lender may, without cost or expense to any of it, use such of Borrowers' personnel, supplies, computer equipment and space at its places of business as may be reasonably necessary for the handling of collections. 8.6 Accounts Documentation. Each Borrower shall maintain its shipping forms, invoices and other related documents in a form reasonably satisfactory to Lender and each Borrower shall maintain its books, records and accounts in accordance with GAAP consistently applied. Each Borrower shall keep and maintain, at its cost and expense, satisfactory and complete books and records of all Accounts, all payments received or credits granted thereon, and all other dealings therewith. At such times as Lender may reasonably request, each Borrower shall deliver to Lender, all original documents evidencing the sale and delivery of -75- goods or the performance of services which created any Accounts, including, but not limited to, all contracts, orders, invoices, bills of lading, warehouse receipts, delivery tickets and shipping receipts, together with schedules describing the Accounts and/or written confirmatory assignments to Lender of each Account, in form and substance satisfactory to Lender and duly executed by such Borrower, together with such other information as Lender may request. In no event shall the making or the failure to make or the content of any schedule or assignment or such Borrower's failure to comply with the provisions hereof be deemed or construed as a waiver, limitation or modification of the security interest in, lien upon and assignment of the Collateral or the representations, warranties or covenants under this Agreement or the other Financing Agreements. Any documents, schedules, invoices or other papers delivered to Lender, pursuant to this Section or otherwise, may be destroyed or otherwise disposed of by it one (1) year after the same are delivered, unless Borrowers make written request therefor and pay all expenses attendant to their return, in which event Lender shall return same when its actual or anticipated need therefor has ceased. 8.7 Specific Powers. Each Borrower hereby constitutes Lender and its designees, as such Borrower's attorney-in-fact, with power of substitution, at the cost and expense of Borrowers, to exercise at any time all or any of the following powers which appointment, being coupled with an interest, shall be irrevocable until all Obligations have been indefeasibly paid in full: (a) to receive, take, endorse, assign, deliver, accept and deposit, in the name of Lender or such Borrower, any and all checks, notes, drafts, remittances and other instruments and documents or chattel paper, in each case to the extent relating to the Collateral; (b) to transmit to Account Debtors notice of Lender's interest therein and to request from such Account Debtors at any time, in the name of Lender or such Borrower or that of Lender's designee, information concerning the Collateral and the amounts owing thereon; (d) on or after the occurrence of an Event of Default, or an event which with notice, passage of time or both would constitute an Event of Default, to notify Account Debtors to make payment directly to Lender; (e) on or after the occurrence of an Event of Default, or an event which with notice, passage of time or both would constitute an Event of Default, to take or bring, in the name of Lender or such Borrower, all steps, actions, suits or proceedings deemed by Lender necessary or desirable to effect collection of the Collateral; and (f) to execute in such Borrower's name and on its behalf any UCC financing statements relating to the Collateral or amendments thereto. Each Borrower hereby releases Lender and its officers, employees and designees, from any liability arising from any act or acts under this Agreement or in furtherance thereof, whether of omission or commission, and whether based upon any error of judgment or mistake of law or fact, except for acts of gross negligence or wilful misconduct of Lender as determined pursuant to a final non-appealable order of a court of competent jurisdiction. -76- SECTION 9. EFFECTIVE DATE; TERMINATION; COSTS 9.1 Term. (a) This Agreement and the other Financing Agreements shall become effective as of the date hereof and shall continue in full force and effect for a term ending on the date three (3) years from the date hereof (the "Renewal Date") and from year to year thereafter, unless sooner terminated pursuant to the terms hereof; provided, that, Lender or Borrowers may terminate this Agreement and the other Financing Agreements effective on the Renewal Date or on the anniversary of the Renewal Date in any subsequent year by giving to the other parties hereto at least sixty (60) days prior written notice. This Agreement and all other Financing Agreements must be terminated simultaneously. (b) In addition, Lender may terminate this Agreement and the other Financing Agreements, or terminate only the provisions of this Agreement as to future Loans and Letter of Credit Accommodations, immediately at any time upon the occurrence of an Event of Default or an act, condition or event which with notice or passage of time or both would constitute an Event of Default. (c) Upon the effective date of termination or non-renewal of the Financing Agreements, Borrowers shall pay to Lender in full, all outstanding and unpaid Obligations (including, but not limited to, the Loans and all interest, fees (including the early termination fees provided herein, if applicable), charges, expenses and other amounts provided for hereunder, under the other Financing Agreements or otherwise) and shall furnish cash collateral to Lender in such amounts as Lender determines are reasonably necessary to secure Lender from loss, cost, damage or expense, including reasonable attorneys' fees and legal expenses, in connection with any contingent Obligations, including Letter of Credit Accommodations and any checks or other payments provisionally credited to the Obligations and/or as to which Lender has not yet received final and indefeasible payment. Such payments in respect of the Obligations and cash collateral shall be remitted by wire transfer in Federal funds to such bank account of Lender, as Lender may, in its discretion, designate in writing to Borrowers for such purpose. Interest at the Interest Rate shall be due until and including the next Business Day, if the amounts so paid by Borrower to the bank account designated by Lender are received in such bank account later than 12:00 noon, New York, New York time. (d) No termination of all or any part of the Financing Agreements shall relieve or discharge either Borrower of its duties, obligations and covenants under the Financing Agreements until all Obligations have been fully indefeasibly discharged and paid, and the continuing security interests of Lender in the Collateral shall remain in effect until all such Obligations have been fully and indefeasibly discharged and paid. -77- (e) If this Agreement terminates upon the occurrence of an Event of Default or at the request of either Borrower prior to the Renewal Date, in view of the impracticality and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of the lost profits of Lender as a result thereof, Borrowers hereby agree to pay to Lender, upon the effective date of such termination, an early termination fee in an amount equal to: (i) two (2%) percent of the Maximum Credit, if such termination is effective on or prior to the first anniversary of this Agreement; or (ii) one (1%) percent of the Maximum Credit, if such termination is effective after the first anniversary of this Agreement but on or prior to the second anniversary of this Agreement; or (iii) one-half (1/2%) percent of the Maximum Credit, if such termination is effective after the second anniversary of this Agreement but prior to the third anniversary of this Agreement, or if the Agreement continues for any renewal term thereafter, if such termination is effective prior to the last day of such renewal term. Such early termination fee shall be presumed to be the amount of damages sustained by said early termination and Borrowers agree that it is reasonable under the circumstances currently existing. The early termination fee provided for in this Section 9.1 shall be deemed included in the Obligations. -78- 9.2 Expenses and Additional Fees. (a) Each Borrower shall pay to Lender on demand all reasonable costs and expenses that Lender may pay or incur in connection with the negotiation, preparation, consummation, administration, enforcement, and termination of this Agreement and the other Financing Agreements, including, without limitation: (i) reasonable attorneys' and paralegals' fees and disbursements of counsel to Lender and any Participant (including allocated costs of in-house counsel); (ii) costs and expenses (including reasonable attorneys' and paralegals' fees and disbursements, and allocated costs of in-house counsel) for any amendment, supplement, waiver, consent, or subsequent closing in connection with the Financing Agreements and the transactions contemplated thereby; (iii) costs and expenses of lien and title searches and title insurance; (iv) taxes, fees and other charges for recording any agreements or documents with the Office of Patents and Trademarks, the Copyright Office or any other governmental authority, and the filing of UCC financing statements and continuations, and other actions to perfect, protect, and continue the security interests and liens of Lender in the Collateral; (v) sums paid or incurred to pay any amount or take any action required of Borrowers under the Financing Agreements that Borrowers fail to pay or take; (vi) with respect to the Collateral, costs of appraisals, inspections and verifications thereof (including, without limitation, travel, lodging, and meals) and inspections of each Borrower's operations by Lender, Participants or their agents, plus a charge of $650 per person per day for the field examiners of Lender and any Participant; (vii) costs and expenses of forwarding loan proceeds, collecting checks and other items of payment, and establishing and maintaining payment accounts and lock boxes; (viii) costs and expenses of preserving and protecting the Collateral; and (ix) costs and expenses (including reasonable attorneys' and paralegals' fees and disbursements and allocated costs of in-house counsel) paid or incurred to obtain payment of the Obligations, enforce the security interests and liens of Lender, sell or otherwise realize upon the Collateral, and otherwise enforce the provisions of this Agreement and the other Financing Agreements, or to defend any claims made or threatened against Lender arising out of the transactions contemplated hereby (including, without limitation, preparations for and consultations concerning any such matters). The foregoing shall not be construed to limit any other provisions of the Financing Agreements regarding costs and expenses to be paid by Borrowers. (b) Borrowers shall pay to Lender all of its customary charges and fees in connection with (i) any payment, claim or refund relating to the dishonor of any checks or other items of Borrowers or Account Debtors, and (ii) wire transfers to Borrowers. (c) All sums provided for in this Section 9.2 shall be part of the Obligations, shall be payable on demand, and shall accrue interest after demand for payment thereof at the applicable rate of interest then payable hereunder. Lender is hereby irrevocably authorized to charge any amounts payable hereunder directly to any of the account(s) maintained by Lender with respect to Borrowers. -79- 9.3 Survival of Agreement. All agreements, representations and warranties contained herein or made in writing by the parties hereto in connection with the transactions contemplated hereby shall survive the execution and delivery of this Agreement, the other Financing Agreements and the consummation of the transactions contemplated herein or therein regardless of any investigation made by or on behalf of Lender. 9.4 No Waiver; Cumulative Remedies. No failure to exercise, and no delay in exercising on the part of Lender any right, power or privilege under this Agreement or under any of the other Financing Agreements or other documents referred to herein or therein shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, power and privilege. No notice to or demand on a Borrower not required hereunder or any of the other Financing Agreements shall entitle a Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of Lender to any other or further action in any circumstances without notice or demand. The rights and remedies of Lender under this Agreement, the other Financing Agreements and any other present and future agreements between Lender and a Borrower are cumulative and not exclusive of any rights or remedies provided by law or under any of the Financing Agreements or such other agreements and all such rights and remedies may be exercised successively or concurrently. 9.5 Notices.

(a) Lender shall use all reasonable efforts to keep confidential, in accordance with its customary procedures for handling confidential information and safe and sound lending practices, any non-public information supplied to it by Borrowers pursuant to this Agreement -80- which is clearly and conspicuously marked as confidential at the time such information is furnished by Borrowers to Lender, provided, that, nothing contained herein shall limit the disclosure of any such information: (i) to the extent required by statute, rule, regulation, subpoena or court order, (ii) to bank examiners and other regulators, auditors and/or accountants, (iii) in connection with any litigation to which Lender is a party, (iv) to any Affiliate of Lender, (v) to any assignee or participant (or prospective assignee or participant) so long as such assignee or participant (or prospective assignee or participant) shall have first agreed in writing to treat such information as confidential in accordance with this Section 9.7, or (vi) to counsel for Lender or any participant or assignee (or prospective participant or assignee).

If any provision of this Agreement or the other Financing Agreements is held to be invalid or unenforceable, such invalidity or unenforceability shall not invalidate this Agreement or the other Financing Agreements as a whole but this Agreement or the particular Financing Agreement, as the case may be, shall be construed as though it did not contain the particular provision or provisions held to be invalid or unenforceable and the rights and obligations of the parties shall be construed and enforced only to such extent as shall be permitted by law. 9.9 Headings. The headings used herein are for convenience only and do not constitute matters to be considered in interpreting this Agreement. 9.10 Counterparts. This Agreement may be executed in any number of counterparts, and by Lender and Borrowers in separate counterparts, each of which shall be an original, but all of which shall together constitute one and the same agreement. -81- SECTION 10.

SCHEDULE 5.14 TO LOAN AND SECURITY AGREEMENT Environmental Matters 1. Matters with respect to The Doe Run Resources Corporation set forth in the "Environmental Assessment of the La Oroya Metallurgical Complex and The Doe Run Company" dated October 1997 prepared for BT Securities Corporation by Environ International Corporation, a division of APBI's Environmental Sciences Group, Inc. 2. Matters disclosed on Schedule 5.10 hereto. 3. All active and inactive mine and smelter sites are on the Environmental Protection Agency CERCLA list. Information requested and submitted on old Viburnum tailings facility. 4. Primary smelter slag produced by and stored at the Herculaneum smelter is currently exempt from hazardous waste regulation under the Resource Conservation and Recovery Act of 1973, as amended ("RCRA"). However, the Environmental Protection Agency recently published a proposed rule which, if adopted, would require this slag to be managed as a hazardous waste. Certain other waste materials, including baghouse dust, generated at the smelter now recycled in the smelter may also become regulated as hazardous wastes. If the slag or other wastes at the smelter are regulated as hazardous waste, the Company may be required to take corrective action under RCRA at the smelter, as well as to adopt stricter management practices for these wastes. 5. The Herculaneum smelter, currently has not attained the ambient air quality standard for lead promulgated under the federal Clean Air Act. The Company is working with regulators to develop a new three-year compliance plan to begin after fiscal 1998 to implement identified control measures. 6. The Buick smelter area is designated non-attainment for the air lead standard. The last 5 years of monitoring demonstrates the smelter is in compliance and an application has been made to certify the area in compliance. 7. Doe Run's recycling facility is subject to corrective action requirements under RCRA, as a result of a storage permit for certain wastes issued in 1989. This has required and may involve future remediation of solid waste management units at the site. 8. The Environmental Protection Agency is reviewing Maximum Achievable Control Technology ("MACT") for primary smelters but has not at this time proposed a MACT rule. In the event a MACT rule for primary smelters is proposed and adopted by the Environmental Protection Agency, the rule could increase compliance costs at the Herculaneum smelter. 9. The Company's operating facilities have waste water discharge permits issued under the federal Clean Water Act, as amended. It is expected that stricter discharge limits than previously in effect will be included in permits now subject to renewal. As a result, there will be additional treatment facilities required. 10. The Company's mining and milling operations include five mine waste disposal facilities that are subject to Missouri mine closure permit requirements. 11. The Missouri Department of Natural Resources ("MDNR") by letter dated April 11, 1997 issued Notice of Excess Emissions observed on August 1, 1997, at the Herculaneum smelter. After response in writing by Doe Run, MDNR issued a letter dated September 12, 1997 that they will not take additional action. 12. The MDNR issued an air inspection report dated May 13, 1997 of potential Notice of Excess Emissions of an opacity excursion at the Buick facility. After response by Doe Run, an MDNR official gave verbal response that MDNR will probably not issue a NOEE. 13. The NDNR, by letter of February 4, 1997, noticed exceedences of water discharge limits for zinc at the Buick Mine/mill facility. A compliance agreement was entered into in May, 1997, whereby Doe Run paid a $25,000 penalty and constructed a pump-back basin.

No. 1155365 dated October 10, 1997 Report No. 107-97-EM/DGAA/LC Memo No. 2159-97-EM/DGAA In regard to this affair, I am informing you of the following: With the aforementioned report, the Director General of Environmental Affairs has completed the evaulation of the reference documents presented by the company CENTROMIN PERU S.A. requesting the PAMA DIVISION OF LA OROYA METALLURGICAL COMPLEX for the purposes of transferral through the sale of said complex, considering it necessary to divide the pledges assumed in the Program of Adaptation and Environmental Management (PAMA) with EMPRESA METALOROYA S.A. the division of the Appeal has been made with the knowledge of the Ministry of Energy and Mines through Appeal No. 1152485. From the evaluation done the following is indicated: o The sums which are to be assumed by CENTROMIN PERU S.A. and METALOROYA S.A. in order to complete their PAMA pledges will be the following: US$24,187,000 (18.34%) for CENTROMIN PERU S.A. and US$107,575,000 (81.66%) for METALOROYA S.A. the sum of the amounts mentioned corresponds to the figure for the reprogramming of the PAMA approved in R.D. No. 325-97-EM/DGM dated October 6, 1997. o The Timetable of Shares and Investments of CENTROMIN PERU S.A. will be executed within a period lasting until 2005 (9 years) while that of METALOROYA S.A. will last until 2006 (10 years). o Appeal No. 1155365 which requests the division of PAMA presents a summary of the financial economic results consolidated up to August 1997 and a projection up to the month of December. In this projection one can observe that the volume of sales of METALOROYA S.A. for 1997 will be US$263,359,500 which indicates that 1% would be US$2,633,595. What is projected to be invested in each year of PAMA surpasses this calculation of 1% of the sales of METALOROYA S.A. The Director General of Environmental Affairs, according to the report and memo referred to, on the basis of what is stated and considering that that which is proposed is found within the boundaries contained in Environmental Regulation for Mining-Metallurgical Activities, D.S.

OFICIO No 834-00/EM-DGAA/OBSERVACIONES PAMA Referencia : Oficina Recibe : DIRECCION GENERAL DE ASUNTOS AMBIENTALES Folio : 13 Observacion : 4 ANILLADOS [ILLEGIBLE] RESPUESTAS A LAS OBSERVACIONES AL PAMA DE LA UNIDAD METALURGICA DE LA OROYA INTRODUCCION Con fecha 23 de Octubre de 1996, su despacho emitio un documento, sobre la Evaluacion del Cumplimiento del PAMA de la Unidad Metalurgica de La Oroya, en el cual luego de comentar los siguientes puntos: Diagnositico de los problemas ambientales, Soluciones propuestas a nivel de perfil, Montos y Cronograma de Inversiones y Sanciones, concluia que el PAMA presentado no cumplia con lo requerido para una evaluacion cabal del programa de mitigacion, por existir observaciones de precision y detalle que debian subsanarse dentro de los 60 dias siguientes. Adicionalmente con fecha 28 de Octubre de 1996, se recibio el Oficio No 334-96-EM/DGAA, en cual se remitia la relacion de 37 observaciones planteadas al PAMA, que era el detalle de la Evaluacion de Cumplimiento. EVALUACION DE CUMPLIMIENTO DEL PAMA Los comentarios y observaciones realizados al respecto, se refieren principalmente a falta de informacion, profundidad de analisis y precision de las inversiones, que aparentemente no le dan al PAMA la solidez que el programa amerita y que la ley exige. 2.1 DIAGNOSTICO DE LOS PROBLEMAS AMBIENTALES Se reclama informacion existente y que fuera presentada y aprobada en el EVAP, como es el caso de los efluentes liquidos, residuos solidos y depositos. Adicionalmente se solicita muestreo de suelos afectados de La Oroya, con la finalidad de una mejor cuantificacion de los impactos, para lograr las mejores medidas de mitigacion. 2.2 SOLUCIONES PROPUESTAS A NIVEL DE PERFIL Se considera que las soluciones propuesta de mitigacion son descriptivas y generales, no siendo congruentes con los montos y cronogramas, en especial lo referente al problema del SO2. 2.3 MONTOS Y CRONOGRAMA DE INVERSIONES Se requiere un mayor sustento de montos y tiempos, en especial debe considerarse los montos minimos de iversion annual, equivalente al 1% de las ventas anuales, senalado por ley. 2.4 RELACION DE LAS OBSERVACIONES PLANTEADAS Las 37 observaciones planteadas, se refieren a puntos especificos que deben ser subsanadso, a fin de que el PAMA, cumpla con los dispositivos legales vigentes, y se constituya como el elemento de gestion que permita alcanzar los niveles amibientales esperados, adecuadonse a las regulaciones amibientales vigentes. RESPUESTAS A LAS OBSERVACIONES PLANTEADAS 3.1 CONSIDERACIONES GENERALES Debe indicarse que el PAMA presentado el 30 de Agosto, ?????????????????? Reiterativamente al EVAP, documento aprobado, considero que no era pertinente repetir la informacion que en el se consignaba, motivo por el cual el PAMA adolece de esta informacion dando la apariencia de superficialidad. Esite informacion detallada referente a los puntos observados, que no fueron reportados en el PAMA, por consideraciones de simplificacion, que fue objeto de una interpretacion de omision. Las soluciones propuestas al Control Ambiental, han sido desarrolladas en su mayoria por empresas extranjeras consultoras de reconocido prestigio, quienes propusieron tecnologias de aplicacion de alta eficiencia, por lo que consideramos soluciones viables y confiables. Los montos indicados para inversiones, supera a la inversion minima annual exigida por ley, no existiendo riesgo en la ejecucion del programa, pro tratarse de montos inferiores a los que normalmente se manejan y que no comrprometen la gestion empresarial. 3.2 RESPUESTAS Con el proposito de dar respuestaa las observaciones planteadas, el PAMA ha sido sometido a una revision exhaustiva, complementando detalles, incrementandto informacion adicional, que en algunos casos supera lo solicitado y mejorando su estructura para ofrecer un documento de mas facil comprension.

COMPONENTES AMBIENTALES o Las actividades del Complejo Metalurgico La Oroya, originan emisiones gaseosas con materiales particulados, efluentes liquidos y residuos solidos que afectan a la calidad del aire, los cursos de agua receptores y los suelos. o El ambiente fisico del emplazamiento se caracteriza por tener una topografia agreste, surcado por lor ios Yauli y Mantaro. El clima es firo, seco entre los meses de mayo a octubre y lluvioso de noviembre a abril. Los vientos son de baja velocidad y de direccion predominante Sur-Este. El agua para uso domestico tiene como fuente el rio Tishgo (185 1/s), mientras que para uso industrial (1 076 1/s) se tiene los rios Mantaro, Tishgo y el manantial de Cuchimachay. Para emergencias existen las fuentes del subsuelo Hidro y Mayupampa. Gran parte de los efluentes liquidos domesticos e industriales, se descargan sin ningun tratamiento a los rios Yauli y Mantaro. El aire recibe la descarga de las emisiones gaseosas y material particulado que se generan en los procesos metalurgicos que son diariamente monitoreadas en cinco estaciones (Huancha, Sindicato, Hotel Inca, Cushurupampa y Casaracra) distribuidas en un radio de 10 km del punto de ubicacion del emisor principal (chimenea de 167,5 m de alto). Las rocas mas antiguas del emplazamiento pertenecen al Grupo pucara sobreyaciendo a las rocas del Grupo Mitu. Estan presentes tambien rocas del Grupo Goyllarisquizga y del Grupo Machay. Pueden apreaciarse en las proximadades al Complejo, afloramientos importantes de roca clacarea con muy pequenas areas de suelo con escasa vegetacion. o El ambiente biologico del eplamzamiento se enmarca en la bioregion de la Serrania Esteparia en las vertientes Occidentales de los Adnes entre los 1000 y 3800 m.sn.m, caracterizada por la presencia de vegetacion que forma una estepa de gramineas que constituyen los pastos naturales. Los rios son de aguas rapidas y tormentosas que disminuyen su temperatura con la altura originando diversos habitats acuaticos. En La Oroya con excepcion de la forestacion conducida por Centromin Peru S.A. la forla y la fauna es escasa, debido a sus caracteristicas geologicas,altitud, topografia y en parta a la accion de las emisiones gaseosas de la Fundicion, lo que contrasta con el escenario de gramieneas y herbaceas de habitos perennes que se encuentra en Casaracra a 10 km de distancia. Las aguas del rio Tishgo en este lugar son utilizadas en acuicultura de la trucha arcoiris, observandose adiconalmente la presencia de gviotas de la puna, aves que se ven a lo largo de las riveras del rio Mantaro incluso hasta las proximadades de l Fudicion. Al Sur de La Oroya siguiendo el curso del rio mantaro en un radio de 7 km., no se ha observado especies representativas de fauna, ni existe vegetacion tipica con excepcion de escas presencia de ichu. En general las condiciones del emplazamiento y su entorno, asi como la calidad de sus suelos, no permiten el uso de la tierra para fines productivos, habiendose efectuado forestaciones con plantas traidas por Centromin Peru, de otros lugares o ciudades proximas, algunas de las cuales se han adaptado al lugar. Ademas, las pracitcas ganaderas PAMA COMPLEJO METALURGICO - LA OROYA Resumen Ejecutivo III - -------------------------------------------------------------------------------- Desordenas y el sobrepastoreo de algunas areas, limitan la regenreracion natural de los pastos, no favoreciendo el mejoramiento del habitat para un mayor desarrollo de la flora y fauna de esta zona. o El ambiente socio-economico del emplazamiento incluye a los grupos humanos de la Comunidad de huari y Hacienda Quilla en la ruta hacia Huancayo, la Comunidad de Hauynacancha en la ruta hacia Lima y la Hacienda Antahuaro, Paccha y Casaracra en la ruta hacia Tarma. De los 67 700 habitantes de la Provincia de Yauli, 30 900 corresponden a La Oroya de los cuales 3 215 son trabajadores de Centromin Peru S.A y de quienes dependen economicamente 13 728 personas. La Oroya se divide en dos grandes sectores: La Oroya Antigua asentada en la margen izquierda del rio Manataro al Nor-Oeste de las instalaciones de la Fundacion y la Oroya Nueva en la margen derecha. A 11 km., de la Oroya en la ruta hacia Lima se ubica el proyecto de viviendas "Curipata", patrocinado por Centromin Peru S.A. en beneficio de sus trabajadores, dentro de un plan de reordenamiento urbano. El emplazamiento se caracteriza por estar ubicado en la unica ruta de acceso a Lima y otras ciudades de la Costa y de retorno desde Lima a las ciudades de toda la Sierra y Selva Central. Las actividades productivas del Complejo Metalurgico La Oroya sustentan la existencia de una zona urbana importante. Las acitividades artesanales son practicamente inexistentes destacando las acitvidades comerciales (987 establecimientos) de servicios (228 establecimientos) e industriales (83 establecimientos). Destaca la presencia de empresas de Servicios Publicos (Telefonos, Correo, Bancos, Transportes, y Emisoras Radiales y de TV locales). Existen 56 escuelas y colegios, a los que asisten un total de 13 192 alumnos de todos los niveles. Existe un Policlinico del IPSS con 72 camas, el Ministerio de Salud cuenta con tres centros de salud y Centromin Peru S.A., cuenta con un Hospital con 50 camas. o El ambiente de interes humano del emplazamiento, esta reducido a constituir una ruta de accesoa ciudades y lugares donde existen recursos arqueologicos (Tarma, Jauja, Huancayo), areas naturales protegidas, parques y reservas nacionales (Bosque de rocas de Huayllay en Cerro de Pasco y Lago de Chinchaycocha en Junin), circuitos turisticos (Lima-Tarma-Valle de Chancahnayo y Valle del Mantaro) y razones socio-economicas. OPERACIONES METALURGICAS o El Complejo Meetalurgico esta conformado por (3) circuitos integrados para el tratamiento de concentrados de Cobre, Plomo y Zinc. En 1995 se procesaron 255 109 t de concentrados de Cobre, 191575t de concentrado de Plomo y 154 710t de concentrado de Zinc. Se estima que para 1996 el procesamiento de concentrados alcance el mismo orden de las cifras mencionadas. o Las caracteristicas de los coentrados tratados, de naturaleza polimetalica, colocan al Complejo dentro de las cuatro (4) del mundo, capaces del procesar este tip de materia prima, obteniendo productos de reconcida calidad internacional. PAMA COMPLEJO METALURGICO - LA OROYA Resumen Ejecutivo IV - -------------------------------------------------------------------------------- IMPACTOS AMBIENTALES o Se ha identificado tres generadores de impacto: Las emisiones de gases y material particulado, los efluentes liquidos y los residuos solidos. En 1995 se descargaron a la atmosfera por la chimenea principal 899,8 t/dia de SO2 y 8,9 t/dia de material particulado, representando este ultimo solo el 3% del total generado. El 7,2% de azufre que ingreso al proceso, se fijo en forma de acido sulfurico, el 4,3% se fijo en los residuos solidos y el 80,5% se descargo a la atmosfera en forma de anhidrido sulfuroso. Las emisiones gaseosas fugitivas impactan igualmente al aire, pero dificiles de cuantificar por no ser regulares y generalmente se dispersan rapidamente. o Los efluentes liquidos generados en la Fundicion se descargan al rio mantaro por (37 emisores y los generadores en las Refinerias de Cobre y Plomo se descargan por (3) emisores al rio Yauli. De ellos (6) en la Fundicion y uno (1) en la Refineria de Cobre, se caracterizan por se los principales contribuyentes de contaminacion. Debe indicarse, que ambos rios en especial el Yauli, llegan a La Oyora con un alto contenido de contaminantes industriales. o Los residuos solidos industriales: Escorias de Cobre y Plomo y pulpa de Ferritas de Zinc, se depositan en la zona de Huanchan a ters (3) Km., al Sur de la Fundicion. El Trioxido de Arsenico en cambio, se deposita en la zona de Vado distante 9 km., al Norte de la Fundicion. La basura industrial es incenerada tanto en la Fundicion como el la Refineria de Cobre y Plomo, mientras que la basura domestica es depositada en el lugar denominado Cochabamba, distante 9 km., al Sur de la Fundicion. Estos depositos tnato de residuos solidos como de basura, por no haber considerado en su disenos originales los aspectos ambientales, actualmente se constituyen en elementos que contaminan los suelos y el agua de lso rios que se encuentran proximos a ellos. MEDIDAS DE MITIGACION o Desde 1922 segun las demandas de la epoca, se ha venido incorporando mejoras ambientales en el Complejo Metalurgico La Oroya sin alcanzar los NMP vigentes al presente. Las necesidad de mejorar las condiciones ambientales dentro del area de influencia impulso entre 1981 y 1983 la construccion y puesta en marcha de la Nueva Planta de Aglomeracion. Entre 1990 y 1992 se iniciaron y completaron las pruebas metalurgicas para cambiar los indice de las camas de cobre que han permitido reducir la generacion de SO2 escorias y materiales particulados en 50 000, 80 000 y 1 40 t/ano respectivamente. En enero de 1994 se concluyo la construccion y montaje de la Nueva Planta de Oxigeno de 312 t/dia de capacidad y en febrero se puso en marcha el reverbero de cobre con quemadores oxy fuel, reduciendose el consumo de petroleo pesado en 20 000 t/ano. A la fecha, se ha desarrollado un Programa de Modernizacion e Innovacion Tecnologica, que adiconado a la implementacion de diversas mejo ambientales que se vienen ejecutando, evidencian un cambio de actitud humana hacia el manejo ambiental responsable, dirigido a mitigar los impactos existentes. o Para mitigar los impactos originados por la descarga de SO2 y materiales particualdos a la atmosfera, se ha proyectado la construccion de 2 modulos, para fijar de acuerdo con la norma ambiental el 83% del total de SO2 generado, produciendo un volumen de 505 000 PAMA COMPLEJO METALURGICO - LA OROYA Resumen Ejecutivo V - -------------------------------------------------------------------------------- Totaliza 90 millones de US$ y conforme al cronograma los modulos entrarian en operacion en los anos 2003 y 2005. o Para mitigar los impactos ambientales originados por los efluentes liquidos de la Fundicion que se descargan al rio Mantaro, se proyecta la construccion de una Planta de Tratamiento, solucion de tecnologia comprobada que ha sido propuesta por la Consultora ECOLAB SRL, donde se ha considerado, la reduccion de volumenes de agua industrial, la recirculacion parcial del agua de recirculacion y la eliminacion de cinco efluentes. El costo del proyecto asciende a 3,3 millones de US$, de los cuales 2,5 corresponden a la Planta, su implementacion se ha programado para los anos 1998-1999. o La mitigacion planteada para los impactos de contaminacion liquida y solida del rio Mantaro, originados por la disposicion de escorias de cobre y plomo, plantea el uso de 2 dessguadores rotatorios INBA y n nuevo sistema de transporte para escorias granuladas a un costo de 6,5 millones de US$. El proyecto se ejecutara en el periodo 1997-1998. o El proyecto para Abandono de los Depositos de Escorias propuesto por RESCAN PERU S.A., plantea la estabilizacion de taludes, obras de captacion de efluentes de infiltracion y escorrentias que comtaminan suelo y aguas, con un costo de 5,25 millones de US$. El proyecto que considera adicionalmente, la recuperacion y restauracion del area, se implemenatra en el periodo 1997-2001. Para el nuevo deposito ubicado en Cochabamba y cuya construccion se iniciara el ano 2002, se tiene una inversion de 25, millones de US$. o Para le proyecto de Abandono de los Depositos de Trioxido de Arsenico, se efectuara el encapsulamiento de los residuos de Malpaso y Vado, con geotextiles y geomembranas, solucion propuesta por ADI INTERNATIONAL INC., con una inversion de 8,7 millones de US$. Se contempla tambien, la construccion de un nuevo deposito en el ex-aeropuerto de Vado, por un monto de 2,0 millones de US$, que se ejecutara a partir del ano 1999. Este tipo de solucion es recomendad por la EPA de los Estado Unidos. o El proyecto de Abandono de las Ferritas de Zinc, considera los trabajos de estabilidad, controlo de efluentes acidos y el de arrastre de particulas por accion eolica. La solucion planteada por RESCN PERU S.A., y que alcanza la suma de 5,6 millones de US$, incluye la respectiva restauracion del area y sera ejecutada en el periodo 1997-2000. Sin embargo, debido al alto valor de los contenidos metalicos de las Ferritas de Zinc (230 millones de US$), como medida alternativa de remediacion, se ha contemplado el reprocesamiento de las mismas con tecnologia de punta, aspecto que se viene evaluando. PLAN DE CIERRE o La importancia que el Complejo Metalurgico tiene dentro del desarrollo soci-economico de la region, hacne que la probabilidad de cierre de sus operaciones no sea predecible en el corto ni mediano plazo. o La decision de cierre, estar suepeditada a considerar no solo aspectos, sino tambien aspectos economicos, y politicos, que involucran acciones de planeamiento detallado, cuyo proceso de ejecucion podria realizarse en forma glogal o parcial. En esta direccion, se ha concebido y estruturado un Plan de Cierre/Abandono eficaz, dirigido a proteger la salud y seguridad publica, mitigar los efectos ambientales detrimentales y promover su pronta recu- PAMA COMPLEJO METALURGICO - LA OROYA Resumen Ejecutivo VI - -------------------------------------------------------------------------------- Peracion, a partir del cese de las operaciones metalurgicas, dentro de un marco tecnico y encomicno factible. Asi mismo, se considera la utulizacion productiva futura de las areas del emplazamiento. PLAN DE MONITOREO DE EMISIONES Y EFLUENTES o Centromin Peru S.A.,es responsible de implementar y mantener programas de monitoreo a tiempo real, basados en sitemas de muestreo adeacuado y en analisis mecanicos, fisicos y quimicos, permitiendo la realizacion de una evaluacion y control de emisiones gaseosas, efluentes liquidos, residuos solidos, ruido y otros elementos que puedan ser generados dentro del Complejo Metalurgico La Oroya y que afecten al entorno de su influencia. o El plan para el monitoreo ambiental del Complejo Metalurgico, que ha sido elaborado en base a los protocols emitidos por la autoridad respectiva, sera reajustada conforme ser vayan implementando los proyectos de mitigacion. La infraestructura exitente permite cumplir con las exigencias vigentes, proviendose su modernizacion permantente y la adquisicion de nuevos instrumentos. El plan contempla asi mismo, un programa de capacitacion tecnico, legla y de relaciones institucionales. INVERSIONES o Para solucionar el problema ambiental del Complejo Matalurgico, se ha considerado dos (2) principales rubros de inversion. El primer, una modernizacion con cambio de tecnologia de los procesos, con la finalidad de lograr mejores niveles de comepetividad y mejora ambiental, principalmetente para la concentracion de SO2, facilitando de esta manera la fabricacion de acido sulfurico. Estimandose para tal fin una inversion de 141,0 millones de US$. El segundo, para el Programa de Adecuacion y Manejo Ambiental (PAMA), con una inversion estimada de 129,1 millones de US$, el cual en gran medida complementara con la modernizacion de los procesos. o Ambos rubros que totalizaron un monto de 270,1 millones de US$, se ha programado para el perido 1997-2006. Esta cantidad estimada, fue confirmado por la firma consultora KILBORN-SNC-LAVALIN EUROPE, en octubre de 1996. o De acuerdo a ley, se tiene una obligacion minima para el PAMA, del equivalente al 1% del valor de las ventas anuales. En ese sentido, el Complejo le conrresponderia un monto de inversion annual minima de 4,5 millones de US$. o Si se tiene en cuenta que el nivel de inversion que realiza el Complejo para su continuidad operativa mejora de proceso y control amibiental, ha sido del roden de los 8 a 16 millones de US$ anuales en los ultimos anos, sin tener en cuenta los proyectos de modernizacion ejecutados que superan el monto senalado para el PAMA, se considera que el programa presentado es viable y no afectara los resultados economicos de la gestion empresarial. PAMA COMPLEJO METALURGICO - LA OROYA Resumen Ejecutivo VII - -------------------------------------------------------------------------------- CONCLUSIONES o La ejecucion del presente PAMA, permitira alcanzar los NMP exigidos por las autoridades del sector. o El programa es viable desde el punto de vista tecnico, al ser necesario tecnologias reconocidas y probadas. En el aspecto economico no significa un deterioro de la gestion empresarial y sera completado en los 10 anos asignados para la adecuacion de las operaciones metalurgicas. o El monto de ivnersion para el PAMA sera de 129,1 millones de US$ y de 141,0 para la modernizacion. o Las emisiones gaseosas, constituyen el principal agente contaminante del emplazamiento, razon por la cual, el 70% de la inversion del programa esta orientado a la fijacion del SO2, enforma de acido sulfurico, cuya demanda de mercado esta garantizado, por su aplicacion a nivel mundial en megaproyetos de yacimientos de Cobre, oreintados a la lixiviacion. o La implementacion del programa, permitira colocar al Complejo Metalurgico, entre la empresas que garantizan un desarrollo sustentable de su emplazamiento y entorno, mejorando el habitar y el nivel socio-economico de las futuras generaciones.

DESCRIPCION DE LOS COMPONENTES AMBIENTALES Los componentes ambientales se agrupan en 4 categorias ambientales: o Ambiente Fisico o Ambiente Biologico o Ambiente Socio-Economico o Ambiente de Interes Humano 2.1 Ambiente Fisico 2.1.1 Topografia - La Oroya El entorno topografico al Complejo Metalurgico La Oroya es accidentado, esta formado por grandes depresiones. El rio Yauli, tributario del rio Mantaro, en su recorrido pasa por un cinturon de topografia plana donde se han formado varios poblados. El rio Mantaro cruza la ciudad de La Oroya de Norte a Sur formando un valle muy estrecho. Aguas abajo del rio Mantaro, despues de La Oroya y en la ruta hacia Huancayo, el valle se hace mas estrecho y abrupto predominando los macizos rocosos de gran altura. En la parte alta, por la margen derecha del rio Mantaro, la topografia se hace ligeramente plana con muchas huellas de surcos producidos por las lluvias intensas que caen en esta parte de la zona. En la parte mas alta sigue predominando la topografia accidentada. En los planos No 1.3/1 y 1.3/2 del Capitulo 1 se presenta la descripcion del entorno topografico en el area de influencia del Complejo Metalurgico de La Oroya. 2.1.2 Abastecimiento Hidrico El abastecimiento de agua industrial y de consumo humano en La Oroya, es esquematizado en el diagrama 2.1.2/1, indicandose los siguientes sistemas: Sistema Tishgo: Tiene como fuente de abastecimiento al rio Tishgo, y su punto de captacion se encuentra ubicado a 14 Km. al norte de la ciudad de La Oroya. Sistema Cuchimachay: Tiene como fuente de abastecimiento el manantial de Cuchimachay, el agua captada se destina para abastecer de agua potable a la poblacion de La Oroya Antigua y a la Fundicion para el sistema de los calderos de vapor. Bombas Rio Mantaro: El agua captada del rio Mantaro es destinado integramente para granular las escorias de la Fundicion de cobre y plomo. Sistema de Emergencia: Estos sistemas entran en operacion cuando falla el sistema Tishgo y son los siguientes: PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 11. - -------------------------------------------------------------------------------- - Bombas Hidro: Este sistema capta el agua de subsuelo en la zona de Hidro y lo envia al tanque de Railway. - Bombas Mayupampa: El sistema es similar al anterior. El agua captada es enviada al tanque Chulec. La siguiente tabla, muestra el analisis fisico-quimico del agua captada de los tres sistemas.

Las precipitaciones se canalizan por pequenas quebradas como tributarios de arroyos y/o al rio Mantaro que es el colector de la cuenca regional. Las caracteristicas meteorologicas son de gran importancia en los fenomenos de contaminacion atmosferica y sus efectos adversos. El registro de los parametros meteorologicos (direccion y velocidad de vientos) en el area de La Oroya, se lleva a cabo en tres estaciones ubicadas: la primera, en la zona de Fundicion y las otras dos restantes con monitores Kimoto Tipo 332-TW en Cushurupampa (NO de la Fundicion) y Huanchan (SE de la Fundicion), respectivamente. La Estacion Meteorologica del complejo metalurgico data desde el ano 1925, la misma que registra parametros como: direccion y velocidad de vientos, precipitaciones pluviales, temperatura ambiental-humedad relativa y presion barometrica. Los resultados obtenidos no son de uso exclusivo de la Empresa, sino que se comparten mediante informacion continua pre-establecida, con el organismo ofi- PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 12 - -------------------------------------------------------------------------------- cial de meteorologia del pais, formando parte de la red de estaciones del Servicio Nacional de Meteorologia e Hidrologia - SENAMHI, bajo cuyos lineamientos se opera. a) Direccion y Velocidad del Viento La informacion correspondiente se registra en el diagrama 2.1.3/1 y tabla 2.1.3/1 del analisis de tales datos destacan caracteristicas relacionadas con la direccion de los vientos. El viento matinal (entre las 7 y 10 a.m.), sopla de norte a sur por el valle del Mantaro, y despues de las 10 am., se invierte de sur a norte. Las rosas de viento, (Diagramas Nos. 2.1.3/1, 2.1.3/2 y 2.1.3/2A) para las dos estaciones urbanas muestran con claridad la ausencia de vientos predominantes; las direcciones registradas forman practicamente las rosas de viento completas, lo que significa que la generacion de los vientos y su recorrido ocurren en todas las direcciones posibles. Relacionando este fenomeno con la distribucion de contaminantes, en una primera aproximacion, resulta facil comprender que no existen zonas continuamente expuestas sino que la difusion se dinamiza segun las circunstancias dominantes particulares y tienden mas bien a estabilizarse sobre la estrecha cuenca del Mantaro - Yauli. En las tablas y diagramas que muestran los promedios de velocidades, se aprecian vientos por debajo de 2 m/s, que para la contaminacion atmosferica se consideran poco favorables, pues no permiten las "barridas" de aire deseables. Excepcionalmente en la rosa de viento de la Estacion Huanchan (Diagrama 2.1.3/1) se aprecia que los vientos van hacia el Sur-Oeste (rio abajo de las aguas del Mantaro), lo que resulta favorable a su difusion. Un aspecto importante que merece atencion en los fenomenos micro-meteorologicos y mas directamente relacionados a vientos, es la influencia de la orografia de la zona. El comportamiento de los vientos en la atmosfera de La Oroya parece ser condicionada en gran medida por la abrupta orografia que limita las zonas industrial y urbana. b) Precipitaciones El mes mas lluvioso es enero y el de menos precipitacion julio (106,5 mm H20 y 0,0 mm H20 respectivamente). Normalmente las precipitaciones (liquidas como lluvia o solidas como nieve) en zonas de contaminacion atmosferica se consideran beneficas porque "lavan" el aire ambiental. Sin embargo, en el caso de La Oroya se le relaciona con un efecto negativo, pues constituyen una fuente adicional de contaminacion al Rio Mantaro, porque esa accion de "lavado" ocurre sobre superficies que han acumulado contaminantes a traves del tiempo y que son disueltos y arrastrados hacia los rios receptores Yauli y Mantaro. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 13 - -------------------------------------------------------------------------------- Se cuenta con la estacion de la Fundicion, y la sub-estacion de Mayupampa para las mediciones pluviales. Los valores promedio anual senalan 568,10 mm de agua para la estacion Fundicion en un periodo de 72 anos y de 563,70 para la de Mayupampa en un periodo de 39 anos (Tabla 2.1.3/2). c) Temperaturas y Humedades Relativas La temperatura en La Oroya y alrededores oscila con marcada diferencia (tabla No. 2.1.3/3 y diagrama 2.1.3/3), llegando a la maxima temperatura (26 degrees C) en el mes de diciembre y la minima (-4 degrees C) en mayo. En cuanto a la humedad relativa tambien es muy variada, oscilando desde 5% en los meses de julio-setiembre, hasta 72% en los meses de enero-marzo. Estos datos que no corresponden a las condiciones meteorologicas locales normales, en conjunto, generan condiciones meteorologicas contradictorias que aumentan o reducen los efectos de la contaminacion ambiental. d) Presiones Barometricas En la Estacion de la Fundicion se miden tambien las presiones barometricas expresadas en KPa (kilo pascales), cuyos valores promedio mensuales horaria se condensan en la Tabla 2.1.3/4. Estos valores, son fundamentales para los calculos de dispersion de las emisiones. En cuanto a promedios mensuales, la presion maxima sucede en el mes de octubre y la minima en diciembre (66,14 KPa y 65,14 KPa respectivamente), siendo la variacion minima. 2.1.4 Aire El aire del ambiente circundante al Complejo Metalurgico La Oroya ha sufrido alteraciones en su calidad a consecuencia de las emisiones gaseosas y material particulado propio de las operaciones metalurgicas. Se tiene 5 estaciones de monitoreo, ubicadas en diferentes puntos de las zonas perifericas de la fundicion (tabla 2.1.4/1), habiendose determinado y evaluado los contaminantes respecto a la calidad del aire ambiental. Los contaminantes evaluados comprenden a los gases sulfurosos expresados en SO2, los materiales particulados en suspension (MPS) y contenidos metalicos (As y Pb). Los resultados del monitoreo en las cinco estaciones, se muestran en las Tablas 2.1.4/2, 2.l.4/2A, 2.1.4/3 y 2.l.4/3A y ademas se detalla en la tabla 7.2.4/1 del Capitulo 7, la descripcion de las estaciones de monitoreo en el area circundante del complejo. A continuacion se indican los valores de la calidad del aire del monitoreo por parte de la Empresa versus los niveles maximos permisibles. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 14 - -------------------------------------------------------------------------------- CALIDAD DEL AIRE AMBIENTAL NIVELES MAXIMOS CIRCUNDANTE AL COMPLEJO PERMISIBLES RM- PARAMETRO UNIDAD (5 ESTACIONES DE MONITOREO) 315-96-EM/VMM ppm SO2 Media aritmetica De 0,06 a 0,24(*) 0,20 diaria Mu g/m3 Pb Media aritmetica De 0,07 a 2,94(*) 0,50 anual As mu g/m3 Media arjunetica De 0,1 a 1,7(*) 6,00 diaria mu g/m3 MPS Media artitmetica De 86,0 a 294,0(*) 350 diaria (*) Generalmente los valores mas altos arrojan cuando se presenta las inversiones termicas. Materiales Particulados en Suspension (MPS) La evaluacion de los contaminantes particulados se efectua por dos metodos independientes uno del otro, pero en las mismas estaciones de muestreo, de modo que es interesante referirlos comparativamente. En un caso, los monitores Kimoto tipo 331- TW, son capaces de evaluar los MPS igual que los equipos de alto volumen (Hi-Vol). Sin embargo, existe la diferencia fundamental de que los Hi-Vol manejan volumenes muy altos de aire de donde se filtran los MPS totales, de manera integral en periodos de 24 horas continuas o mas; en cambio, en los muestreadores de cinta, el muestreo es secuencial (cada 3 minutos) y en consecuencia pueden obtenerse valores maxirnos, minimos y promedios. Algo mas importante aun es que en el metodo de la cinta o mancha de papel, las particulas evaluadas son unicamente la fraccion de dimensiones menores a 10 micras, conocidas como PM10. Es decir que del total de particulas flotantes del aire, el equipo es capaz de discriminar (mediante un sistema de cicloneo) las porciones de PM10, llamadas tambien respirables, que por esa razon tienen mayor valor respecto a la salud publica. Los Hi-Vol como ya se dijo, colectan todos los materiales no sedimentables, entre los cuales abundan las particulas mayores a 10 micras. Estas diferencias conceptuales y de operacion explican a su vez, las diferencias en los valores hallados. Contenidos Metalicos en los MPS Tanto en muestras de MPS captadas por la cinta de papel o por el metodo Hi-Vol se hacen determinaciones para detectar tres elementos quimicos contaminantes (As, Pb y Cd), presentes en los materiales procesados. Estas determinaciones se efectuan mediante marchas analiticas de laboratorio en compositos mensuales representativos. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 15 - -------------------------------------------------------------------------------- 2.1.5 Geologia y Sismicidad - La Oroya a) Geologia Las rocas mas antiguas que afloran en el ambito de La Oroya son las pertenecientes al Grupo Pucara de edad Triasico-Jurasico, compuestas principalmente por calizas gris claro a blanco que deben estar sobreyaciendo a las rocas del Grupo Mitu de edad Permica. Tambien estan presentes rocas del Grupo Goyllarisquizga, compuestas de areniscas y lutitas rojas, capas de calizas, interestratificadas con capas basalticas o diabasas. Sobreyaciendo a estas rocas se encuentra el Grupo Machay, compuesta de calizas gris azuladas y bituminosas de la formacion Pariatambo y las calizas claras, lutaceas, margosas y fosfatadas de la formacion Chulec. Al Sur de La Oroya se encuentran afloramientos correspondiente a las Capas Rojas de edad Terciaria; cubriendo a estos afloramientos se tienen una serie de depositos cuaternarios, habiendose distinguido los siguientes: o Depositos Aluviales Estos depositos irregulares se encuentran en los rios Mantaro y Yauli formando terrazas de diferente edad y dimensiones dentro del Cuaternario. La Fundicion de La Oroya y las Refinerias de Huaymanta, se encuentran asentadas sobre este tipo de depositos. Las dimensiones de los fragmentos varian entre bloques, gravas, gravillas y algo de arena. La composicion de estos materiales es variada. o Depositos Fluvioglaciares Este tipo de deposito se encuentra en las partes altas como restos de antiguos glaciares, en muchos casos solo quedan remanentes de antiguos depositos grandes. o Depositos Coluviales Estos depositos se encuentran formando los taludes de las escarpas rocosas que se han formado por erosion de las rocas. Son depositos pequenos e irregulares. o Depositos Eluviales En algunas partes es posible encontrar rocas que se estan transformando a suelos y son pequenos depositos que estan dando origen a suelos. b) Plegamiento y Fallamiento Las rocas adyacentes al curso del rio Mantaro se encuentran fuertemente plegadas con buzamientos proximos a la vertical y en algunos casos se han dislocado formando fallas regionales. Hacia el Suroeste y Noreste del rio, el plegamiento se suaviza formando anticlinales y sinclinales amplios. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 16 - -------------------------------------------------------------------------------- c) Geomorfologia En el ambito circundante al Complejo Metalurgico La Oroya, se pueden distinguir algunas caracteristicas geomorfologicas, tales como: el rio Mantaro con algunos tributarios como el rio Yauli, Shincamachay, Huashango (Paccha), Pacchapata (La Oroya Antigua), rio Seco y algunas otras quebradas menores que han excavado su cauces en rocas calcareas, areniscas, lutitas, etc. de las diferentes formaciones rocosas. En las partes altas se puede distinguir remaentes de la superficie puna inicial. Sobre los cauces antiguos de los rios Mantaro y Yauli principalmente, se aprecian terrazas fluviales y en algunos lugares depositos de precipitacion quimica (travertinos) tales como, los depositos de Sacco-Tambo, Shincamachay, confluencia del rio Tishgo y Mantaro y otros mas pequenos como en La Oroya Antigua (cubierta por la poblacion). La altitud varia, dentro del ambito de La Oroya, entre los 3 600 y 4 600 m.s.n.m., ubicandose la Fundicion y Refinerias a una altura promedio de 3 750 m.s.n.m. Tambien son muy claras las formaciones actuales de carcavas (grietas de erosion), producidas por las lluvias acidas en los alrededores de La Oroya, sobre la superficie del suelo que ha quedado sin proteccion vegetal natural (ichu). Este efecto erosivo es intenso en los alrededores de la Fundicion y disminuye paulatinamente conforme se aleja de este centro. d) Area Sismica Desde el punto de vista Tectonica, el Complejo Metalurgico La Oroya se encuentra localizado en la Zona 1 (Reglamento Nacional de Construcciones) que corresponde a una zona de alta sismicidad, indicando esta que para las construcciones se debe tener en cuenta los parametros antisismicos que indica el Reglamento entre otros y que los edificios deben ser principalmente de dos pisos o menos. 2.1.6 Evaluacion de Suelos Es de enorme importancia el estudio y la evaluacion de estos recursos naturales, los cuales son estudiados en sus aspectos fisicos, quimicos y biologicos. Los estudios se hicieron sobre muestras tomadas en las zonas afectadas, asi como de las zonas aledanas. Los resultados de los analisis mostrados en la Tabla 2.1.6/1, indican que se trata de suelos empobrecidos estando sin cobertura vegetal. No hay presencia de nitrogeno (por falta de vegetacion), asi mismo carecen de calcio; en su mayoria son suelos ligeramente acidos debido precisamente a la remocion del calcio por efecto de las precipitaciones pluviales sobre suelos pobres en vegetacion y al efecto adverso de los humos de la Fundicion. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 17 - -------------------------------------------------------------------------------- En las muestras tomadas en la zona de La Oroya Antigua, frente aal complejo metalurgico los resultados del analisis indican la presencia de carbonato de calcio en gran porcentaje, lo cual se deberia a la disgregacion que sufren las rocas calizas que coronan el cerro en su parte alta. Asi mismo, su pH tambien es ligeramente alcalino y su textura es de un terreno que difiere de los suelos del sector Huaynacancha que son aridos y arenosos. 2.2 Ambiente Biologico 2.2.1 Caracterizacion La Bioregion de la Serrania Esteparia, abarca desde el Departamento de La Libertad hasta el norte de Chile y en la vertiente Occidental de los Andes, entre los 1 000 y 3 800 m.s.n.m. con una interesante formacion ecologica caracterizada por factores climatologicos, edaficos, floristicos y faunisticos propios. Toma el nombre de serrania esteparia por la formacion vegetal mas sobresaliente. Presenta un clima muy diferente al desierto costero y al de la Puna, con los cuales limita al Oeste y Este respectivamente. (Diagrama 2.2.1/1). a) Ecosistema Terrestre Caracterizado por la presencia de una vegetacion que forma una estepa de gramineas, comunidades de Lupinus, algunas plantas herbaceas de los Generos Baccharis, Polylepis, Buddelia, Alnus asociadas con gramineas como: Stipa ichu, Stipa bhrachyphylla, Calamagrostis vicunarum, Calamagrostis antoniana y Festuca heterophylla que constituyen los pastos naturales. (Diagrama 2.2.1/2). En la Serrania Esteparia las intensas y desordenadas practicas ganaderas, destruyen la vegetacion silvestre impidiendo la regeneracion natural y ocasionando la erosion de los suelos. La principal causa de la desaparicion de las especies en esta zona, tanto de la flora como la fauna silvestre y especialmente las endemicas que presentan distribucion restringida, es la destruccion del habitat, por la perdida de la vegetacion natural. La fauna esta representada por la Vizcacha (Lagidium puna). La fauna de esta zona esta altamente influenciada por elementos de la Puna, llegando las especies de la serrania esteparia a su limite superior de distribucion. Entre la Avifauna podemos destacar la presencia de la "tortolita peruana" (Euphelia cruziana), los picaflores (Myrtis fanny) y (Thaumastura cora) el "negro" (Dives warszewiezi) el "tordo negro" (Molothrus bonariensis) el "chisco" (Mimus longicaudatus). PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 18 - -------------------------------------------------------------------------------- b) Ecosistema Acuatico Los rios de las vertientes occidentales son de aguas rapidas y torrentosas, disminuyendo la temperatura de los mismos con la altura, lo que trae como consecuencia una interesante zonacion de habitats acuaticos, entre los que podemos mencionar. Lechos de rio con corriente, arroyos andinos, barrancos de tierra y piedras, orillas desnudas con piedra, orillas rocosas, orillas de rio con vegetacion baja. Entre las aves mas caracteristicas de este ecosistema mencionaremos al "Pato de los torrentes" (Merganetta armata) y al "Mirlo acuatico" (Cinclus lencocephalus) prefiriendo los rios, arroyos de aguas cristalinas y de corriente rapida. Entre los anfibios son frecuentes: el "Sapo comun" (Bufo spinolusus), asi mismo especies como (Telematobius jelskii) y (Telematobius runac). Los peces nativos han sido poco estudiados, pero podemos mencionar a la "Chalwa" (Oretias spp.) y las introducidas como la trucha (Salmo spp). 2.2.2 Ecosistemas - Complejo Metalurgico La Oroya y su entorno El Complejo Metalurgico esta ubicado en la quebrada que forma la cuenca de los rios Mantaro y Yauli a 3 750 m.s.n.m. Los centros poblados y las zonas de cultivo se encuentran proximos a las cuencas de los rios Yauli y Tishgo. Se hace una descripcion de los ecosistemas terrestre y acuatico en un radio de 10 Km haciendo centro en la chimenea principal de la Fundicion. a) Ecosistema Terrestre El Complejo Metalurgico La Oroya, se encuentra ubicado dentro de los valles mesoandinos, con una superficie total de 9 209.83 Ha, las que se encuentran distribuidas de la siguiente manera: 1. Seis concesiones mineras no metalicas : 4 500.00 Ha 2. Nueve predios rusticos : 2 669.83 Ha 3. Tres canteras : 2 040.00 Ha Geograficamente el complejo ocupa la parte occidental de los Andes de la zona central entre los 3 700 y 3 800 m.s.n.m. y esta aledana a las haciendas y comunidades siguientes: - Hacienda Antahuaro - Comunidad Oroya Antigua - Hacienda Tallapuquio - Comunidad Huaynacancha - Hacienda Huaymanta - Comunidad de Huari - Hacienda Quiulla El relieve topografico es accidentado con laderas fuertes y suelos acidos con tonos rojizos o pardos. Asi mismo se encuentran suelos poco fertiles (combisoles districos) y eutricos (fertiles) PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 19 - -------------------------------------------------------------------------------- La flora propios de la zona adyacente al Complejo Metalurgico se viene dando en forma espontanea, en la Tabla 2.2.2/1 podemos observar el analisis quimico de las plantas. (Foto 2.2.2/1). A 10 Km al norte de La Oroya se encuentra Casaracra. Este lugar esta constituido por gramineas y herbaceas de habitos perennes que son dominantes como la Festuca heterophylla y la Stipa ichu. Debido al pastoreo prolifera la "Choca" (Chuquiragua huamanpinta), el "Caqui Caqui" (Adesmia spinosisima) y algunas cactaceas. (Foto 2.2.2/2); la fauna del lugar son ovinos y vacunos. Las aves son muy escasas entre las que podemos mencionar a la "Gaviota de la puna" (Lorus serranus). En todo este recorrido se ha podido observar especies arbustivas solo por actividad de repoblacion forestal tales como el colle (Buddleia coriacea) el Polylepis racemora. Tambien se ha identificado a la retama y el maguey (Agave americana). Al Sur de La Oroya y bordeando el rio Mantaro y en un radio de 7 Km. no se observa vegetacion tipica de la region a excepcion del Stipa ichu y en forma muy escasa debido a la accion de los humos de la Fundicion. A partir de esta zona se comienza a observar vegetacion mas tupida asi como en la parte alta y del talud del rio, gramineas como la Festuca sp y la Stupa ichu. Asimismo algunas especies como Quishuar y algunas cactaceas propias de la zona. (Foto 2.2.2/3). En la parte alta, al Oeste de La Oroya (aproximadamente a 4 000 m.s.n.m.) se observa directamente el efecto de los humos de la fundicion sobre el ecosistema. Se ha calculado un area de 3 829 Has aun pendiente por recuperarse, se ve claramente los efectos sobre el suelo (Foto 2.2.2/4). En la parte media del valle de Huaynacancha existe una pequena laguna formada por los deshielos y lluvias donde toman agua algunas vicunas y se aposentan aves como la "Huallata" o "Washwa" y en forma muy escasa especies de vegetacion almohadilla y gramineas. A 10 kms a la redonda del complejo, se puede comprobar la existencia forestal frente a la residencia de empleados (Hotel Inca), de las oficinas generales del complejo y en las poblaciones aledanas con especies como el Colle, Quinhual, Cipres, Quishuar, etc., propios de la zona. b) Ecosistema Acuatico Ambiente Lotico: Rio Tishgo, rio Mantaro y rio Yauli. El rio Tishgo se une al rio Mantaro a la altura de la Hacienda Casaracra y sus agua son utilizadas, previo tratamiento para uso domestico y hace algun tiempo, utilizadas en acuicultura de la "Trucha arco iris", no se han reportado especies de peces en otros organismos acuaticos. La vegetacion riberena esta formada principalmente por gramineas. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 20 - -------------------------------------------------------------------------------- El rio Mantaro que discurre de Norte a Sur, trae en su recorrido altas concentraciones de contaminantes y que a su paso por La Oroya recibe el aporte de los efluentes de la Refinerias de Cobre y Plomo a traves del Rio Yauli que trae algunos contaminantes como residuos de relaves. El efluente de agua de granulacion de escorias de cobre y plomo, del canal principal No. 2 de Fundicion de Cobre y Plomo, de las soluciones de la Planta Electrolitica de Zinc, del canal principal No. 1, del canal paralelo del punto 135 y del efluente de las pozas de ferrita de Zinc. En los rios receptores Yauli y Mantaro, no se ha observado organismos representativos de flora y fauna excepto la "gaviota de la puna" (Lorus serranus) y la Huallata. En la Tabla No. 2.2.2/2 se presenta los valores del monitoreo de los rios Tishgo, Yauli y Mantaro. Como se puede apreciar los rios Yauli y Mantaro estan contaminados con plomo en concentraciones mayores que el Limite Maximo Permisible, el cadmio considerado como uno de los elementos mas peligrosos tambien se reporta en el Rio Mantaro. El fierro aumenta su concentracion en el Mantaro a su paso por la fundicion y el manganeso aumenta 5 veces su concentracion. Tambien se encuentra presente el arsenico; ademas, ambos rios reciben emisiones domesticas de toda la poblacion. 2.3. Ambiente Socio Economico El Complejo Metalurgico La Oroya contribuye al bienestar y desarrollo socio-economico del pais y en particular de la region central, mediante la produccion de metales refinados de alta calidad y sub-productos requeridos en la industria nacional en primer lugar y dando atencion al mercado externo. 2.3.1 Descripcion del Componente Socio-Economico a) Ubicacion y descripcion del Complejo Metalurgico La Oroya como Asentamiento Minero y los Asentamientos Humanos de su entorno Las instalaciones del Complejo Metalurgico La Oroya se ubican en la Ciudad de La Oroya. Los principales centros poblados del entorno cercano son: En la via que conecta con Huancayo: La Comunidad de Huari, Hacienda Quiulla En la via a Lima: La Comunidad de Huaynacancha. En la via de Salida a Tarma estan: La Hacienda Antahuaro, y despues de Paccha la zona de Casaracra. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 21 - -------------------------------------------------------------------------------- En la ruta Oroya - Cerro de Pasco existe 8 poblados mas.

Mapa de Necesidades Basicas Insatisfechas de los Hogares. INEI 1995. Vemos que entre el Distrito de La Oroya y Santa Rosa de Sacco absorben el 64,1% de la poblacion de la Provincia de Yauli; y ambos son Distritos altamente urbanizados. En lo que se refiere a los trabajadores de la Empresa, encontramos que el 92% son casados y proceden en su mayoria de la zona central del Pais: 79% de Junin, 5% de Cerro de Pasco, 5% de Huancavelica y 11% de otros. El 33% de trabajadores tienen de 1 a 3 hijos y un 40% de 4 a 5 hijos. Ademas el 90,4% de las esposas de trabajadores viven en La Oroya. De los 3 215 trabajadores dependen economicamente 13 728 personas. El 43% de los trabajadores tienen entre 31 y 45 anos y un 32% mas de 46 anos. El 63% de trabajadores tienen instruccion secundaria. Por otra parte debemos senalar que el crecimiento demografico de La Oroya sigue mostrando una tasa negativa respecto a 1981. La disminucion de la poblacion de La Oroya en el periodo 81-93 (-1.4) se debe esencialmente a las politicas de Racionalizacion de Personal que Centrormin implemento en la epoca de crisis de la mineria y en el proceso previo a la privatizacion.

Norman King - ------------------------------ --------------------------------------- En el sector de la calle Lima que es la principal de este sector, agrupa viviendas de obreros y empleados de Centromin, gran cantidad de comercios muchos de ellos en kioscos y ambulantes. En este sector hay un pequeno mercado. En el sector de Alto Marcavalle (Foto 2.3.1/2) en el Cerro de Yantacancha que pertenece al Distrito de Santa Rosa de Sacco se produce un fenomeno que tipifica el proceso de urbanizacion de los cinturones poblacionales del entorno de la ciudad de La Oroya y esta constituido por los AA.HH. Tambo del Sol (Villa Sol), Muruhuay, Maria Concepcion y Tacarpana. Estos cuatro presentan caracteristicas semejantes y colindan unos a otros teniendo servicios comunes como una Antena Parabolica, una Radio-Emisora (Super A.M.) y un Estadio. El AA. HH. mas grande es "Tambo del Sol"; el 90% de los habitantes son trabajadores de Centromin, propietarios de lotes de 200 m2 con casa de 2 pisos de adobe, con huertas y crianza de animales. Cuenta con 130 familias y todos los terrenos estan ocupados. Los pobladores para poder obtener los terrenos se constituyeron en Nuevos Comuneros integrados a la Comunidad Santa Rosa de Sacco proceso que empezo en 1981. (Foto 2.3.1/3). PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 24 - -------------------------------------------------------------------------------- Urbanizacion Curipata A 11 km de La Oroya en la ruta hacia Lima se encuentra el proyecto de viviendas Urb. Curipata patrocinado por Centromin para sus trabajadores. Se situa al lado de la carretera en una zona plana y bien planificada (proyecto de Postas, Estadio, Colegio, Iglesia, Mercado, etc.). (Foto 2.3.1/4). En cuanto al Complejo Metalurgico de La Oroya sus instalaciones productivas se encuentran ubicadas en una zona mas o menos amplia (Ver Diagramas 2.3.1/1 y 2.3.1/2). Asi: En la ruta hacia Lima a lo largo de la Carretera Central y el Rio Yauli en el sector Huaymanta estan situados una Bodega, la Planta de Alambron de Cobre, la Refineria de Cobre y Plomo. En la ruta hacia Tarma se ubica el Club y el Hotel "Inca" la Central Hidroelectrica de La Oroya, el sector de Chulec con el Hospital y el Colegio Mayupampa. A lo largo de la Av. Horacio Zevallos estan ubicados: o El canal de TV de Centromin Peru S.A., RR.PP., el Hotel Junin, las oficinas de recursos Humanos Sierra y Relaciones Industriales y al final de la Av. Horacio Zevallos frente a La Oroya Antigua (al otros margen del rio Mantaro) esta la Fundicion de Cobre, Fundicion de Plomo, Refinerias de Zinc, El area de Capacitacion, Seguridad, Medicina Ocupacional, asi como la Gerencia Central de Operaciones. (Foto 2.3.1/5) b) Actividad Economica de La Oroya y su entorno La ciudad de La Oroya esta rodeada por zonas agricolas, ganaderas y mineras de la Sierra Central caracterizadas por sus explotaciones agricolas medianas, orientadas hacia el abastecimiento de los mercados de Huancayo, Tarma y Chanchamayo, productos alimenticios como la carne de la zona de Junin; verduras, papas, legumbres de la zona de Tarma y del Valle del Mantaro; frutas y cafe de la region de Chanchamayo;. insumos industriales de origen pecuario (lana); materias primas minerales (esencialmente Cobre, Plomo, Zinc y Plata) para el mercado nacional y externo, provenientes de Centromin (Morococha, Casapalca, San Cristobal, Yauricocha, Cobriza y Andaychagua). La Oroya es tambien punto de retorno para abastecer de alimentos (abarrotes) y productos finales de vestir, mobiliario, etc. a toda la zona de la Sierra y Selva Central. Hacia la zona de Tarma, Huancayo y Junin encontramos una serie de pequenas poblaciones (generalmente estancias o poblados correspondientes a Comunidades Campesinas) ubicadas en las inmediaciones de la Carretera Central las que deben su existencia principalmente a las actividades ganaderas y agricolas a pequena escala (autoconsumo, vendiendo lo poco excedente) y pequenos servicios orientados al transporte (restaurantes, mecanicas, etc.). Sin em- PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 25 - -------------------------------------------------------------------------------- bargo, pese a su cercania de La Oroya, su relacion se reduce a la comercializacion de sus productos en las dos ferias semanales de esta ciudad, ya que la mayoria de los productos alimenticios acabados (abarrotes) proceden de la ciudad de Lima. (Foto 2.3.1/6). Las actividades artesanales propias del lugar son practicamente inexistentes, pues, como hemos visto el porcentaje de la poblacion dedicada a la actividad metalurgica y junto con sus familiares dependientes constituye el 34,1% de la PEA de la Ciudad, existe un 51,9% de la PEA estable repartida entre el comercio y servicios de diferente indole entre los que se cuentan a los empleados de la Instituciones Publicas y privadas. Todos los cuales si bien dependen directa o indirectamente de la actividad de la Empresa constituyen rubros diferentes. Un ejemplo que demuestra esta dependencia, es el hecho que las ferias semanales y quincenales realizados en La Oroya y Santa Rosa de Sacco coinciden con los dias de Pago de la Planilla Diaria de los trabajadores. En lo que se refiere al sector comercial, se han encontrado 987 establecimientos entre formales e informales, de los cuales el 59,9% pertenecen al rubro alimentos (abarrotes, verduras, etc.), 6,9% a vestido y calzado y en menor medida a enseres domesticos y artefactos electricos. El 74,8% de las empresas comerciales son de tipo familiar que involucran a mas de dos miembros de la familia. En el sector de servicios se han registrado 228 establecimientos de los cuales el 31,1% son restaurantes formales y el 8,3% son vendedores informales de comida, y existe 29 Mecanicas y Factorias dedicadas a prestar servicio a los transportistas. El sector industrial de la ciudad de La Oroya, esta conformado por 83 establecimientos de los cuales el 36,3% son lugares de expendio de bebidas alcoholicas, siguiendo en importancia los rubros de confecciones y panaderia con el 15,6%, la fabricacion de muebles con el 21,6%. Tambien existe una embotelladora y fabricas de cal y yeso. El 15,9% de los trabajadores de Centromin realizan actividades economicas complementarias: 5,9% se dedican al comercio, 9,2% a servicios (albanileria, gasfiteria, mecanica) y 0,78% a otros. Un 13,6% de esposas de trabajadores se dedican a otra actividad economica aparte de las actividades de ama de casa (mayormente se dedican al comercio 8,5%, y lo hacen en la Oroya). Dada la importancia que ha adquirido la Ciudad de La Oroya en los ultimos anos en ella vienen funcionando distintas Instituciones Gubernamentales, Municipales y Privadas y varias ONG. Existen 35 Instituciones entre Publicas y Privadas. En cuanto a empresas privadas de servicios publicos estan: La Telefonica del Peru, Correos, Bancos, Servicios de Transporte y Emisoras Radiales locales.

PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 26 - -------------------------------------------------------------------------------- Existen 4 cooperativas entre las que se encuentran la "Cooperativa de Ahorro y Credito CENTROMIN Coop 299". Aparte de esto La Oroya tiene ocho comedores populares con organizaciones de base integradas por mujeres de bajos recursos economicos y 18 Clubes de Madres participan en: Programa de Vaso de Leche, PANFAR. c) Infraestructura habitacional y de Servicios Basicos - La Oroya o Infraestructura Habitacional La infraestructura habitacional de La Oroya se divide en dos clases, la primera a cargo de la administracion de Centromin Peru y la segunda a cargo de particulares. Esta ultima, es la que se constituye en una problematica social, por su tugurizacion, construcciones de mala calidad, falta de servicios basicos y otros, situacion que se agrava por las invasiones de las partes altas, lugares de mayor exposicion al impacto de las emisiones gaseosas. La Empresa en La Oroya cuenta con un total de 3 395 viviendas que asigna a sus trabajadores, de las cuales 1 064 (31%) estan en condiciones adecuadas de habitabilidad y 2 331 (69%) en condiciones regulares. Estas viviendas albergan aproximadamente. una poblacion de 15 376 personas con un promedio de 5 a 6 personas por familia. Estas viviendas estan situadas en los siguientes sectores: Tras el Mercado, Calle Lima, Railway, Cantagallo, La Florida, Alto Peru, Plomo 1 piso, Plomo 2 pisos, Huaymanta, Buenos Aires "A", Esmeralda, Santa Rosa, Buenos Aires "B", Huampani, Marcavalle, Tras Estacion. El 83% de los trabajadores viven en casas asignadas por la Empresa (742 en zonas particulares) las que en su mayor parte consta de 2 habitaciones. (Foto 2.3.1/8) En las viviendas ubicadas en blocks y que son departamentos cuenta con los servicios higienicos, lavanderia y duchas en el interior; en cambio en los sectores donde se tiene la construidos blocks de cuartos, los servicios son colectivos: letrinas lavanderia, pozas y duchas. Se observa que el 38% de trabajadores tienen casa propia (el 9,74% en La Oroya); el 27% tienen tereno (el 7,28% en La Oroya). Foto 2.3.1/9. El promedio de viviendas de La Oroya es de 2 pisos y 60 m(2) de area de terreno y 50 m(2) de construccion por piso, son de material noble, en su mayoria con pisos de cemento, ventanas de madera y techos de madera y calamina. Tambien existen casas de adobe, sobre todo en la parte particular de La Oroya Antigua. En total en La Oroya existen 11 256 viviendas. Las condiciones de las viviendas, sobre todo en los sectores: Tras el Mercado, Av. Wilson, Alto Peru Tras Estacion, Railway y los Plomos presentan un alto grado de deterio- PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 27 - -------------------------------------------------------------------------------- En cuanto al programa de demolicion de viviendas en estado avanzado de deterioro y tugurizacion, a la fecha se ha demolido la totalidad de viviendas del sector "Club Peruano" (existian 460 viviendas), en este espacio se ha sembrado grass. En la zona de la Fundicion se han demolido practicamente todas las viviendas existentes habiendose dispuesto convenientemente del material de demolicion. La Urbanizacion Curipata patrocinada por Centromin Peru para sus trabajadores orientada a la casa propia y despoblar la zona industrial o Educacion En materia de educacion, existen dos sistemas de Educacion en La Oroya uno de ellos bajo la administracion de la USE (Unidad de Servicios Educativos Fiscalizados) que tiene a su cargo 09 Colegios Fiscalizados (3 de Educacion Inicial, 4 de Primaria y 2 de Secundaria) de Centromin Peru S.A, los que cuentan con buena infraestuctura, equipamiento y un plantel docente de excelente calidad integrados por 296 trabajadores. Estas unidades gozan de prestigio academico y cuenta con un total de 4 408 alumnos (setiembre de 1996) que representa el 33,5% de la poblacion escolar. (Foto 2.3.1/7). El otro 66,5% de la poblacion escolar lo constituye los 8 744 alumnos que estudian en los 45 centros de educacion, Primaria, Secundaria, Tecnico Ocupacional y Superior del sector publico y privado que constituye el otro sector del sistema educativo de La Oroya: El ADE (Area de Desarrollo Educativo) que cuenta con 450 trabajadores, existiendo tambien Institutos de computacion, enfermeria y educacion. Actualmente los 9 Centros Educativos Fiscalizados (C.E.F.), debido al proceso de privatizacion de CMP S.A., se encuentran en etapa de transferencia al Ministerio de Educacion. o Salud En lo que respecta a salud, la ciudad de La Oroya, incluyendo a Paccha y Santa Rosa de Sacco cuenta con tres sistemas de atencion de salud. -- EL IPSS (Instituto Peruano de Seguridad Social) que cuenta con un Policlinico orientado mayormente a la atencion de personas de la tercera edad y con un Hospital General Regional que cuenta con 25 medicos de todas las especialidades, 35 enfermeras, 72 camas, servicios de rayos X, analisis y atiende operaciones quirurgicas mayores y menores. Brinda servicios de prevencion y asistencia a los asegurados y sus dependientes en su mayoria son trabajadores de CMP. -- EL Ministerio de Salud que cuenta con tres centros de Salud de precaria infraestructura y equipamiento, que brindan servicios (consultas, operaciones menores, analisis, partos) dirigidos a la poblacion que carece de Seguro Social, los casos de salud que requieren mayor atencion son derivados a Tarma, Huancayo y Lima. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo II Pag 28 - -------------------------------------------------------------------------------- -- Finalmente Centromin administra el Hospital de Chulec que cuenta con 14 medicos de distintas especialidades, 13 enfermeras, 50 camas y atiende operaciones mayores (16 como promedio mensual) y operaciones menores, rayos X, analisis, ecografias, larascopias, etc. Brinda sus servicios a familiares de trabajadores de la Empresa que no tienen derechos de atencion en el IPSS, ver tabla siguiente: TIPO DE ATENCION POR SUBPOBLACION

Esta mezcla es sometida a un proceso de Anexo G [GRAPH OMITTED] DIAGRAMA 2.2.1/2 PERFIL ECOLOGICO DE LAS VERTIENTES OCCIDENTALES DE LOS ANDES PERUANOS (Koepcke M.1954) PAMA COMPLEJO METALURGICO-LA OROYA Capitulo III Pag 56. - -------------------------------------------------------------------------------- tostacion para eliminar la mayor cantidad de arsenico (As), azufre (S), algo de antimonio (Sb) y plomo (Pb). Los solidos de los humos del proceso son recuperados en precipitadores electrostaticos (cottrell). En esta planta se obtiene el trioxido de arsenico (As(2)O(3)), que se separa de los procesos metalurgicos, se transporta a granel a la cancha de almacenamiento de Vado, por su baja calidad y mercado restringido. La calcina, producto de la tostacion, pasa a ser fundida en un horno de reverbero con quemadores oxy-fuel, en donde se separan los sulfuros metalicos en la calcina (FeS y Cu(2)S) de la ganga (escoria) y se produce una mata de cobre adecuada para ser cargada y procesada en los convertidores. La escoria es descargada por una abertura ubicada en la pared opuesta a la de los quemadores horizontales, y luego granulada con agua a presion para posteriormente, ser transportada y almacenada en el deposito de escorias de Huanchan. El agua utilizada para la granulacion alcanza los 694 l.p.s. que se descargan al rio Mantaro, situacion que sera eliminada en cuanto se implemente el sistema de recirculacion de agua que se encuentra en su fase final de evaluacion. Una vez carga da la mata a los convertidores, se le insufla aire para generar los oxidos ferrosos, los cuales reaccionan con la silice alimentada, produciendose las escorias, que regresan al reverbero. En una segunda etapa, el sulfuro cuproso es oxidado por el aire, el cual a su vez, reacciona con el mismo sulfuro produciendo el cobre ampollado (cobre blister), que se transfiere al horno de retencion para ser moldeado como anodos. Aqui se tiene en ejecucion un proyecto de instalacion de una tornamesa de moldeo, que usara agua atomizada, disminuyendo el consumo de agua industrial en el enfriamiento de los anodos, permitiendo adicionalmente, el mejoramiento de su calidad fisica. Los solidos contenidos en los humos de las etapas de fusion y conversion son recuperados en precipitadores electrostaticos. Los gases de SO(2) son evacuados a la atmosfera por la chimenea principal. Refineria de Cobre En la Refineria de Cobre, los anodos de cobre blister provenientes de la fundicion de cobre, son sometidos a un proceso de electrolisis, obteniendose un catodo de cobre refinado, el cual es vendido como catodo o fundido y moldeado como wire bar. El electrolito se purga (bleed off) diariamente, separandose aproximadamente 30 000 l/d para mantener el nivel de impurezas en los rangos requeridos por el proceso. Esta solucion es saturada por adicion de chatarra de cobre refinado y evaporacion para producir sulfato de cobre de grado comercial. El 75% de la solucion es retornada como electrolito y el 25% restante es sometida a cementacion con chatarra de fierro para recuperar el cobre. La solucion acida agotada se vierte sin neutralizacion al rio Yauli. Se estudia incorporar un circuito para extraccion por solventes u otro proceso para evitar la contaminacion de este rio. Los lodos anodicos obtenidos son tratado en la Planta de Residuos Anodicos. PAMA COMPLEJO METALURGICO-LA OROYA Capitulo III Pag 57. - -------------------------------------------------------------------------------- Horno Asarco Los catodos de cobre refinado obtenidos de las celdas electroliticas, luego de ser lavados y fundidos en un horno Asarco de columna y el metal moldeado en diferentes formas: barras (wire bars), tapones (pechos) de cobre, lingotes, canales y moldes. El agua de enfriamiento pasa por unas pozas de decantacion y filtracion con paneles de yute que minimizan su contenido de TSS antes de ser vertidas al rio Yauli. Planta Alambron Las barras de cobre son roladas en caliente hasta convertirlas en alambron negro de 5/16" y alambre trefilado de 6,5 mm de diametro. Se dispone de un horno de recocido tipo SALEM que usa como combustible petroleo Diesel, y la reduccion de la seccion de la barra se obtiene a traves de 14 pasos de rodillos trefiladores. 3.4.2. Circuito de Plomo (Diagrama No. 3.4.2/1 y 3.4.2/2) Fundicion de Plomo Se inicia el proceso en la Planta de Preparacion, en donde se dosifica el material recirculante, los fundentes y los concentrados formando las camas de plomo. La cama es tratada en la Planta de Aglomeracion de Plomo en donde se reduce la cantidad de azufre contenido mediante un proceso de tostacion (up draft), produciendose un material aglomerado (sinter) con caracteristicas fisicas apropiadas para ser tratado en los hornos de manga. El material fino originado por el proceso es recuperado en filtros de bolsas y los humos en el precipitador electrostatico central. El aglomerado (sinter) de plomo grueso, es fundido en hornos de manga usando como reductor y combustible el coque, y un porcentaje de chatarra de fierro con el fin de prevenir la formacion de magnetita y evitar la perdida de metales (Pb, Ag) en las escorias. El producto de fusion que sale de los hornos de manga se denomina plomo de obra. Al separar la escoria del plomo de obra, esta se granula con agua a presion para luego ser transportada y almacenada en el deposito de escorias de Huanchan. El agua utilizada en la operacion de granulacion como en el caso de escoria del circuito de cobre, es vertida al rio Mantaro. El plomo, producido en los hornos de manga denominado plomo de obra, es transportado a ollas receptoras donde es espumado. Las espumas son cargadas a un horno de reverbero donde se separa la mata de cobre, el "speiss" (Cu-As, Sb) y el plomo bullon. El plomo bullon retorna a la olla receptora mezclandose con el plomo de obra limpio. Esta mezcla es "decoperizada" con la finalidad de eliminar impurezas (Cu, As y Sb). El plomo, una vez "decoperizado", se calienta y se bombea a las ollas de la seccion moldeo donde se mantiene a 350 - 380(degrees)C, a fin de llevar a cabo el moldeo de anodos en dos tornamesas horizontales. PAMA COMPLEJO METALURGICO-LA OROYA Capitulo III Pag 58. - -------------------------------------------------------------------------------- Refineria de Plomo El plomo bullon producido en la fundicion, con contenidos de antimonio (Sb), bismuto (Bi) y plata (Ag), se refina electroliticamente, por el proceso Betts modificado en la refineria de Huaymanta. Completado el proceso electrolitico, los anodos corroidos quedan con las impurezas insolubles adheridas a sus paredes, y con electrolito ocluido que debe recuperarse. Luego, los lodos son desprendidos con agua a presion (35 000 l/d) y la pulpa se envia al filtro automatico "Larox", obteniendose una torta de lodo anodico con aproximadamente 27% de humedad, listo para su posterior tratamiento en la Planta de Residuos Anodicos. La solucion (filtrado) que sale del filtro Larox es recirculada al circuito de la refineria de plomo. Luego del periodo requerido de deposicion catodica, los catodos son removidos de las celdas de deposicion a los tanques de lavado para recuperar el electrolito y luego ser fundidos en una de las tres ollas de 160 t de capacidad, las que son calentadas con petroleo. El plomo fundido es calentado hasta 450(degrees)C y agitado vigorosamente con hidroxido de sodio (NaOH) para espumar el arsenico, antimonio y estano remanentes. El plomo refinado es moldeado en barras de 46 kg para su comercializacion. El acido hidrofluosilicico requerido para el proceso de electrolisis es fabricado haciendo reaccionar fluoruro de calcio (CaF(2)) con acido sulfurico (H(2)SO(4)), obteniendose por condensacion acido fluorhidrico (NF), el que posteriormente se hace reaccionar con silice fina (Si0(2)) en un reactor. El residuo solido (CaSO(4)), es descargado directamente al rio Yauli, por lo que se esta viendo la posibilidad de construir canchas de almacenamiento para este subproducto. Planta de Residuos Anodicos Procesa los lodos anodicos provenientes de las Refinerias de Cobre y Plomo para la obtencion del DORE (Ag-Au), y otros subproductos como: bismuto, selenio y telurio. La planta dispone de 2 reverberos de fusion de lodos y uno de reduccion de escorias de bismuto; 4 convertidoras; 3 copelas; 7 ollas de bismuto y la seccion Hidrometalurgia y Electrometalurgia para recuperar el selenio y telurio, respectivamente. Refineria de Plata Electrorefina el DORE (Ag-Au) para separar la plata del oro. Se dispone de 124 celdas tipo THUM. 3.4.3. Circuito de Zinc (Diagrama No. 3.4.3/1) Tostacion Los concentrados de zinc provenientes de Paragsha y Mahr Tunel son tratados en tres tostadores de cama fluida (FER) y otro de cama turbulenta (TLR). PAMA COMPLEJO METALURGICO-LA OROYA Capitulo III Pag 59. - -------------------------------------------------------------------------------- Una parte de los concentrados de zinc es mezclada con polvo de oxido de zinc recuperado en el precipitador electrostatico central, para luego ser perdigonado con acido sulfurico. Los concentrados son luego tratados en los tres tostadores de cama fluida, obteniendose perdigones calcinados los que son enviados a la unidad de molienda y cernido. Este producto es almacenado en los silos de la unidad de lixiviacion. Con el SO(2) que se obtiene en el tostador de cama turbulenta se produce acido sulfurico de grado comercial (45 000 t/a). El oxido de zinc recuperado en los ciclones y precipitador electrostatico tambien es almacenado en los silos de la unidad de lixiviacion. Lixiviacion El objetivo principal de la etapa de lixiviacion es el de disolver el oxido de zinc y el sulfato de zinc presentes en la calcina. El proceso de lixiviacion se lleva a cabo en tanques agitadores donde se carga el electrolito gastado y calcina fina. El hierro presente se oxida con bioxido de manganeso y precipita como un compuesto insoluble denominado ferrita de zinc, junto con el As, Sb y otras impurezas. La pulpa obtenida antes de ser enviada a la Unidad de Separacion de Solidos es clasificada en un hidrociclon, separandose la fraccion gruesa (+ 100 mallas) que retorna al primer reactor de Lixiviacion. En la planta de separacion de solidos se separa la solucion impura (overflow) del residuo (underflow); este ultimo es lavado y filtrado para asegurar la maxima extraccion de sulfato de zinc. El residuo (ferritas de zinc), es enviado a la planta de flotacion, en donde se recupera el zinc y la plata en forma de concentrado. Una parte de la cola (ferritas de zinc) remanente es tratada en la planta de residuos lixiviados de zinc (Zileret) y la otra enviada en forma de pulpa al deposito de Huanchan, donde es almacenada, para su probable posterior tratamiento. Purificacion La solucion impura de sulfato de zinc, es derivada a la unidad de purificacion en donde las impurezas como el cobre, cadmio y pequenas cantidades de arsenico y antimonio son precipitadas usando polvo de zinc. Esta solucion es filtrada y el residuo es enviado a la Planta de Cadmio para su tratamiento, mientras que la solucion purificada es enviada a la unidad de electrolisis. La electrolisis de la solucion de sulfato de zinc se realiza entre catodos de aluminio y anodos de plomo-plata Luego de una etapa de deposicion de 16 horas los catodos son extraidos de las celdas y el zinc electrolitico es deslaminado y enviado para ser fundido en un horno de induccion. Fusion y Moldeo Los catodos de zinc obtenidos electroliticamente son fundidos y moldeados en lingotes de 26 kg para su comercializacion.

En estas condiciones el SO(3) se une al agua del acido en la torre de absorcion. b) Planta de coque Esta planta consta de dos baterias independientes que operan paralelamente, cada una con 10 hornos de coquificacion, aprovechando la generacion del propio gas de coque para la combustion y calentamiento de los hornos. El proceso de coquificacion considera los siguientes pasos: o El carbon es descargado de las tolvas hacia el molino de martillos para ser elevado despues por los cangilones hasta la tolva de alimentacion, con una granulometria uniforme. o Luego el material es cargado a cada uno de los hornos horizontales para su coquificacion. o Durante la descarga, cumplido el ciclo de coquificacion el coque producido es evacuado de cada horno, por un "empujado de trompa" hacia un transportador de cadena de arrastre, que lo lleva hasta un "pozo de coque" para finalmente ser enfriado por rociado de agua. o Los gases calientes que salen de los hornos se enfrian por rociado de agua con lo cual se condensa el alquitran, el cual es llevado a un tanque de sedimentacion. o El alquitran libre de agua es enviado al reverbero de cobre para ser utilizado como combustible y el coque, al circuito de fundicion de plomo. c) Planta de oxigeno En esta planta se fracciona el aire liquido en sus componentes, aprovechando las diferentes temperaturas de ebullicion de los mismos. Para llevar a cabo la operacion de fraccionamiento de aire, la planta industrial esta equipada para: Comprimir el aire Evaporar la humedad y el dioxido de carbono del aire Enfriar el aire a la temperatura de licuacion Producir frio Licuar el aire Fraccionar el aire (rectificacion) Separar las impurezas d) Planta de acido fluosilicico La primera etapa de la produccion de acido fluosilicico se realiza en un horno cilindrico rotatorio el cual recibe fluoruro de calcio en polvo y acido PAMA COMPLEJO METALURGICO-LA OROYA Capitulo III Pag 62. - -------------------------------------------------------------------------------- sulfurico lentamente. El control de la temperatura es importante ya que la reaccion al inicio es violenta. El acido fluorhidrico (NF) gaseoso formado en el horno, es conducido a un sistema de dos condensadores enfriados exteriormente con agua en los cuales el gas es absorbido por el agua que fluye en contracorriente a la direccion del gas. El gas que no ha podido ser absorbido por el agua en el primer condensador pasa al segundo condensador a traves de una tuberia de plomo. El acido fluorhidrico obtenido en los condensadores, es enviado a un tanque de mezcla, donde reacciona con silice finamente granulada manteniendo la mezcla en constante agitacion con aire, para producir asi la solucion de acido fluorsilicico (H(2)SiF(6)) para el electrolito de la Refineria de Plomo. 3.5.

Estas emisiones alcanzan no mas del 9% del caudal emitido por la chimenea principal. Sin embargo, son significativas por sus concentraciones de plomo y arsenico (ver Tablas 4.1.1/4 y 4.l.l/4A. o Emisiones por las Chimeneas de Planta de Coque - Baterias A y B Este emisor conduce un flujo de 14,86 Nm^3/seg., de gases, conocidos como gases de desecho. Los gases emitidos por las chimeneas de las baterias A y B son producto de la combustion llevados a cabo en las camaras de calentamiento del proceso de coquificacion, cuyos analisis se consignan en las Tablas 4.1.1/5, 4.1.1/5A, 4.1.l/5B, 4.1.1/5C. o Sistema de Ventilacion de Ollas de Bismuto - Planta de Residuos Anodicos La emision de gases de las ollas de bismuto Nos. 4, 5 y 6 es producto de la oxidacion y clorinacion en la etapa de refinacion de bismuto. Las emisiones gaseosas son previamente purificadas en un lavador de gases. El analisis de las emisiones son consignadas en las Tablas 4.1.1/6 y 4.1.1/6A o Sistema de Ventilacion de Convertidores - Planta Residuos Anodicos La emision de gases de los Convertidores Nos. 1, 2, 3 y 4 es producto de la oxidacion selectiva de antimonio y bismuto en los convertidores y de la reduccion de Bismuto en el reverbero No 3. El material paniculado que acompana a los gases es previamente recuperado en tres unidades de filtros de bolsas. Los analisis de las emisiones son detallados en las Tablas 4.1.1/7 y 4.l.1/7A. o Sistema de Ventilacion de Copelas Planta Residuos Anodicos El sistema de ventilacion de copelas permite la captura de humas metalicos de las copelas Nos. 1, 2 y 3, producto del proceso de oxidacion selectiva de selenio, teluro, y otros elementos menores los que son recuperados en un lavador de gases y precipitador electrostatico humedo. Los gases remanentes se evacuan por una chimenea cuyos analisis son consignados en las Tablas 4.1.1/8 y 4.1.1/8A. o Sistema de Ventilacion de Tostadores de Zinc Las emisiones son de las unidades de perdigonacion y tostacion de cama finida. Las emisiones estan constituidas por gases residuales de SO(2), combustion y material particulado, no recuperado en los lavadores de gaes y PAMA COMPLEJO METALURGICO - LA OROYA Capitulo IV Pag 76. - -------------------------------------------------------------------------------- filtros bolsa, de los procesos de tostacion y del manipuleo de materiales (concentrados, perdigones y calcina). Los analisis de las emisiones se consignan en la Tablas 4.1.1/9 y 4.1.1/9A. o Emisiones en las Refinerias de Cobre y Plomo y Otros El sistema comprende un conjunto de 19 chimeneas ubicadas en la refineria de cobre, plomo, horno asarco y planta de alambron. En la refineria de cobre por la naturaleza del proceso de electro-refinacion, produccion de sulfato de cobre y lixiviacion de lodos anodicos requiere elevar la temperatura de los procesos generando emisiones de vapor de agua y contaminantes menores de acido sulfurico y sulfato de cobre. Las operaciones del horno asarco incluye el enfriamiento de las barras de cobre que producen emisiones de vapor de agua que arrastran particulas inertes de bone ash (desmoldante). La planta de alambron emite vapor de agua (libre de contaminantes) producto del enfriamiento de los rollos de alambron. En la refineria de plomo las emisiones provienen del proceso de electrorefinacion de plomo las que consiste de vapor de agua y contenidos menores de acido fluorsilisico. Tambien hay emisiones de acido fluorhidrico en la planta de acido fluorsilicico. Durante la fusion de catodos de plomo refinado se desprenden vapores metalicos que son captados por medios de campanas y derivados a un filtros bolsas, evacuandose al ambiente los gases residuales. Los gases de combustion con su composicion tipica son evacuados al ambiente independientemente de los gases de fusion. c) Emisiones Fugitivas o Fundicion de Cobre En la planta de preparacion, se producen estas emisiones por arrastre de materiales solidos fuera del alcance de las campanas y esto ocurre basicamente cuando excede la capacidad de los extractores. En la planta de tostadores se reproducen emanaciones de gases SO(2) y solidos que descargan al ambiente directamente desde el piso de carga, por falta de tiro en el ducto principal de evacuacion. Asimismo, se ha observado fugas de gases y polvos generados en las operaciones de descarga de los tostadores de cobre hacia los carros calcineros, al no ser captados por las campanas del sistema de ventilacion. El inadecuado sistema de ventilacion de los convertidores permite la fuga de polvo y emisiones de gases SO(2) al ambiente durante el carguio del material frio recirculante. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo IV Pag 77 - -------------------------------------------------------------------------------- En los hornos de retencion para el moldeo de cobre blister, los gases de combustion y de SO2, se difunden libremente por falta de un sistema de captacion. En la Tabla 4.1.1/10 se presenta la caracterizacion de estas emisiones fugitivas. o Fundicion de Plomo En los hornos de plomo se registran emisiones fugitivas especialmente durante las operaciones de emergencia como parada de hornos, limpieza de columnas de hornos, cambios de tanques de asentamiento, etc. y en las ollas de recepcion y de decoperizado de la planta de tratamiento de espuma por falta de sistemas de captacion. En el horno reverbero de tratamiento de espuma existen emisiones fugitivas especialmente durante las coladas del producto y carga de materiales. En la Tabla 4.1.1/10, se adjuntan las caracteristicas de estas emisiones. o Circuito de Zinc En la planta de tostadores de cama fluida y perdigonacion se producen emisiones fugitivas de material particulado en los sistemas de transporte de calcina. Presencia de material particulado en el ambiente de tostadores de lecho turbulento (TLR) Presencia de vapor de agua con trazas de acido sulfurico en area de enfriadoras de la planta electrolitica de zinc. En la planta zileret existe emisiones de gases y material particulado durante la descarga de esponja de fierro del horno kiln. En la Tabla 4.1.1/10, se resume la descripcion de las emisiones fugitivas de este circuito. o Residuos Anodicos y Refineria de Plata Existe emisiones gaseosas y material particulado durante la descarga del reverbero de fusion y en el trasvase de los materiales fundidos a los convertidores. Esta situacion se agrava por la baja eficiencia de los sistemas de ventilacion. En la Tabla 4.1.1/10 se muestran las caracteristicas de las emisiones fugitivas en esta planta. 4.1.2 Efluentes Liquidos Los efluentes liquidos producto de las operaciones metalurgicas que tienen impacto en los rios receptores Yauli y Mantaro, suman en total 40 efluentes.

Las escorias no tienen valor economico, en cambio las ferritas de zinc por contener este metal en cantidades apreciables, son considerados como una reserva de zinc para ser explotado en el futuro. Respecto al trioxido de arsenico el mercado se encuentra deprimido. Otros materiales de menor impacto son los residuos de talio, la basura industrial y domestica. a) Escorias de Cobre y Plomo Estas escorias se generan en los hornos de manga de plomo y del horno reverbero de cobre, luego de ser granuladas por enfriamiento brusco mediante agua a presion y transportadas por gravedad en forma de "slurry", separacion solido-liquido, se envia por medio de un sistema de cable carril hasta el deposito de "Huanchan". Ver Diagrama 4.1.3/1. El agua que sirve para la granulacion, se descarga en forma directa al rio Mantaro, arrastrando escoria fina en suspension y metales disueltos.

La accion eolica tambien se manifiesta sobre el deposito arrastrando parte de las particulas finas que conforman las escorias. b) Trioxido de Arsenico Este subproducto es generado por la tostacion de polvo recuperado en el cottrell de arsenico mezclado con pirita, el arsenico se volatiliza y los vapores procesados pasan al cottrell caliente y de alli a las cocinas donde el producto obtenido contiene un 96% de As(2)O(3). Por sus escasas ventas, ha sido depositado en dos areas, una desde 1992 en Malpaso, operativo durante aproximadamente 25 anos, y otra en la zona de Vado, en actual uso.

Del cuadro se deduce que se incrementa la concentracion de arsenico en el rio Mantaro despues del stock Vado. En cuanto a los otros elementos como cobre, plomo y fierro se observa infimos incrementos que no sobrepasan los limites maximos permisibles. Referente al pH, no se observa variacion al haberse registrado valores entre 7,3 y 7,8 para ambas muestras de agua. En las Fotos 4.1.3/2A y 2B se observa los depositos de trioxido de arsenico. c) Residuos Lixiviados de Zinc (Ferritas de Zinc) Estos residuos se generan en el proceso hidrometalurgico de lixiviacion de calcinas de zinc. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo IV Pag 84 - -------------------------------------------------------------------------------- De los residuos generados (115 t/d) el 43% (50 t/d ) se procesa en la planta "zileret", la misma que al ser procesada y obtenerse fierro esponja permite ser empleado en los lechos de fusion para transformarse en escorias estables. El remanente de ferritas se depositan en pozas conformadas por diques perimetricos de material prestado. Para satisfacer la creciente demanda de capacidad, las alturas de los diques son constantemente incrementadas siguiendo la metodologia "aguas arriba" sin compactacion ni adicion de humedad. La solucion que trae la pulpa de ferritas es decantada en uno de los extremos de cada poza y evacuado hacia el rio Mantaro por una tuberia enterrada. Las condiciones climaticas tales como vientos y lluvias originan por un lado arrastre de las particulas finas al medio ambiente y disolucion de las sales solubles (ZnSO(4)) que finalmente descargan al rio Mantaro. La seccion de pruebas de control efectua un control de los flujos y contenidos metalicos que dicho efluente descarga al rio Mantaro, los cuales son mostrados a continuacion y representa un promedio de enero-agosto de 1996.

En la Foto 4.1.3/2 se tiene una vista parcial de estos depositos. d) Otros Residuos (Residuo de Talio, Basura Industrial y Domestica) o Residuo de Talio Este residuo solido es generado por el tratamiento de la esponja de cadmio crudo (Planta de cadmio). El residuo es producto de la purificacion del sulfato de cadmio con permanganato de potasio, soda caustica y carbonato de sodio. El material producido es transportado por medio de camiones al deposito de Huanchan (lado sur del deposito No. 2 de ferritas de zinc). Actualmente se tiene almacenado 2 428 t (4 % de Ti promedio). El abandono de este deposito se realizara bajo la misma tecnica de abandono de los depositos de ferritas. Las caracteristicas de este residuo se presentan en la Tabla 4.1.3/2. o Basura Industrial La basura industrial se genera en las instalaciones del complejo metalurgico y esta conformada por: maderas, telas, papeles, plasticos resinas y otros. Actualmente estan en operacion dos incineradores de basura industrial, uno instalado en la fundicion y otro en la Refineria de Huaymanta. La chatarra industrial es seleccionada para su posterior reciclaje parcial o venta, y los aceites industriales y grasas se reciclan a los tanques de petroleo pesado (Bunker 6). PAMA COMPLEJO METALURGICO - LA OROYA Capitulo IV Pag 86 - -------------------------------------------------------------------------------- o Basura Domestica Este residuo es depositado en un lugar denominado Cochabamba 11 km al sur de la Fundicion. 4.2 Evaluacion de los Impactos Ambientales 4.2.1 Impacto sobre el Ambiente Fisico o Clima Este componente es afectado por los gases al producirse el efecto de inversion termica, lo que ocasiona microclimas no propios de la region. o Aire El aire recibe la descarga de las emisiones gaseosas y material particulado que se generan en los procesos metalurgicos que son diariamente monitoreadas en cinco estaciones (Huanchan, Sindicato, Hotel Inca, Cushurupampa y Casaracra) distribuidas en un radio de 10 km del punto de ubicacion del emisor principal (chimenea de 167,5 m de alto) Como producto de la dispersion de gases (Tablas Nros. 4.1.1/2, 4.1.1/2A, 4.1.1/3, 4.1.1/3A, 4.1.1/4, 4.1.1/4A, 4.1.1/5, 4.1.1/5A, 4.l.1/5B, 4.1.1/5C, 4.1.1/6, 4.1.1/6A, 4.1.1/7, 4.1.1/7A, 4.1.1/8, 4.1.1/8A, 4.1.1/9, 4.1.1/9A), la calidad de aire en el entorno del Complejo Metalurgico, alcanza los niveles maximos permisibles, excepto cuando sucede la inversion termica, como se puede apreciar en el siguiente cuadro: - -------------------------------------------------------------------------------- NIVELES MAXIMOS PARAMETRO UNIDAD CALIDAD DEL AIRE PERMISIBLES RM- 315-96-EM/VMM - -------------------------------------------------------------------------------- PPM S0(2), Media aritmeti- De 0,06 a 0,24(*) 0,20 ca anual - -------------------------------------------------------------------------------- ug/m^3 Pb Media aritmeti- De 0,07 a 2,94(*) 0,50 ca anual - -------------------------------------------------------------------------------- ug/m^3 As Media aritmeti- De 0,08 a 1,72(*) 6,00 ca anual - -------------------------------------------------------------------------------- ug/m^3 MPS Media aritmeti- De 86,0 a 294,0(*) 350 ca diaria - -------------------------------------------------------------------------------- (*) Generalmente los valores mas altos arrojan cuando se presenta las inversiones termicas. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo IV Pag 87 - -------------------------------------------------------------------------------- o Agua Los 40 efluentes liquidos, producto de la actividad del Complejo Metalurgico, vienen siendo descargados a los rios Yauli y Mantaro con contenidos solidos en suspencion y metales en solucion con las caracteristicas que se pueden apreciar en las Tablas 4.1.2/1, 41.2/2 y 4.l.2/2A. Por otro lado, la totalidad de los efluentes liquidos domesticos se descargan, a la fecha, sin ningun tratamiento, a los mencionados receptores. o Suelos Las pocas areas de suelos existentes, no son aptos para fines productivos por su composicion y por sus caracteristicas topograficas y geologicas y altitud de la zona. Bajo estas condiciones, el principal impacto viene dado por las lluvias que erosionan los suelos, facilitados por la gran pendiente de estos y por su acidez originada por la parcial disolucion de las emisiones de S02. Los residuos solidos industriales, tales como las escorias de Plomo y Cobre, la pulpa de las ferritas de zinc, impactan los suelos en el area de los depositos de Huanchan, a 3 km. del Complejo Metalurgico. Del mismo modo, el trioxido de arsenico produce un impacto negativo en la zona de Vado a 9 km. del area del mencionado Complejo. La Oroya tienen suelos empobrecidos sin cobertura vegetal. No hay presencia de nitrogeno por falta de vegetacion, asi mismo carecen de calcio y son suelos ligeramente acidos debido a la remocion del calcio por efecto de las aguas pluviales y el efecto nocivo de los humos de la fundicion. Ver fotos 4.2.1/1 y 4.2.1/2. Los suelos de La Oroya y circundantes han sido objeto de estudio en los laboratorios de la Universidad Nacional Agraria de La Molina. En las tablas 4.1.1/2, 4.1.1/2A, 4.1.1/3, 4.1.1./3A, 4.1.1/4, 4.1.1/4A, 4.1.1/5, 4.1.1/5A, 4.1.1./5B, 4.1.1./5C, 4.1.1/6, 4.1.1/6A, 4.1.1/7, 4.1.1/7A, 4.1.1/8, 4.1.1/8A, 14.1.1/9 y 4.1.1/9A se detalla la caracterizacion de los gases emitidos al ambiente los que afectan precisamente a los suelos en mencion. Tambien los suelos son impactados por los residuos solidos provenientes de la basura, que en parte es incinerada y/o depositada en un lugar llamado Cochabamba a 9 km. del Complejo. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo IV Pag 88 - -------------------------------------------------------------------------------- o Geomorfologia La geomorfologia se ve afectada por la modificacion del relieve geografico. Los residuos solidos, pese a su baja solubilidad no estan exentos en contenidos de agentes contaminantes, los cuales se transmiten hacia las aguas superficiales. Las tablas 4.l.3./l y diagrama 4.1.3/1 muestran los volumenes, caracteristicas y ubicacion de los solidos, ademas en el capitulo 5 se presentan en mayor detalle los proyectos de abandono de depositos, ferritas, trioxido y de emisiones. Por accion eolica, las particulas finas de los residuos son desplazados hacia areas del entorno, alterando la calidad de los suelos. 4.2.2. Impacto sobre el medio ambiente biologico El paisaje natural, nos muestra que la atmosfera es receptora de gases y materiales particulados que finalmente al precipitar con la lluvia, constituyen las causas de la alteracion de los ecosistemas existentes afectando la flora y la fauna especialmente, entonces esta parte de la serrania se hace un tanto improductiva inclusive con desaparicion de algunas especies silvestres, especialmente las endemicas de distribucion restringida, hacia la destruccion del habitat, por la perdida de la vegetacion natural. La turbidez del agua, disponible en los rios Mantaro y Yauli especialmente, impide la penetracion de la luz limitando la actividad fotosintetica, reduciendo la cantidad de oxigeno disuelto y modificando la temperatura del agua, estas condiciones definitivamente afecta la productividad primaria de estos rios. Debe indicarse que este impacto se manifiesta antes de la llegada de ambos rios a la ciudad de La Oroya, incrementandose ligeramente con parte de los residuos industriales que descargan las diferentes plantas del Complejo Metalurgico. A lo anteriormente senalado se adiciona la cantidad de solidos en suspencion que traen estos rios como pueden apreciarse en la Tablas 4.1.2/6 y 4.1.2/6A. Los residuos solidos que se observan en los depositos de Huanchan (escorias y ferritas de zinc). Malpaso y Vado (trioxido de As), son un tipo de contaminacion fisica que contribuye a la alteracion de los ecosistemas terrestres (Fotos 4.1.3/1 y 2, 2A y 2B).

Esta planta de lixiviacion, para una produccion de 70 000 t.p.a. de zinc refinado tiene un costo de US $ 40 millones, comparado con el costo de un nuevo TLR y su respectiva planta de acido sulfurico que es del orden de los US $ 52,9 millones. La tecnologia de lixiviacion a presion permitira en la planta Zileret (Horno Kiln de 5O t do capacidad/ dia) pueda emplearse para procesar exclusivamente las ferritas almacenadas en Huanchan; asi mismo tendra otras ventajas tales como: o Se solucionaria el problema de emisiones de gases SO(2) debido a que el azufre se fijaria como azufre elemental, aun cuando es conocido que su mercado es limitado. o Permitira contrarrestar el problema del parque automotor para el transporte de acido sulfurico, asi como tambien la capacidad de almacenaje. - -------------------------------------------------------------------------------- Fuente Consultoras :AUSMELT LIMITED. :BOART LONGYEAR S.A. :KILBORN, SNC.

ALTERNATIVAS PARA LA MITIGACION 3.1 Seleccion del Proceso A fin de mitigar el impacto de las emisiones de SO(2) se ha evaluado procesos alternativos para su fijacion (produccion de yeso, de sulfato de amonio, de SO(2) liquido y de azufre elemental) diferentes a la produccion de acido sulfurico. Acido Sulfurico Se ha optado por la produccion de acido sulfurico como la alternativa mas viable debido a las siguientes razones: PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 157. - -------------------------------------------------------------------------------- o Ofrece una tecnologia convencional probada, conocida y muy difundida. o La demanda potencial de acido sulfurico en el corto y mediano plazos, se localiza en el mercado sudamericano. o El proyecto conlleva un cambio tecnologico importante en las operaciones y procesos del Complejo Metalurgico La Oroya, que apuntan a lograr una mayor competitividad de la Empresa a nivel internacional. o Aproximadamente el 90% de la produccion de azufre en todas sus formas se fija como acido sulfurico o se convierte finalmente en acido sulfurico, del cual, el 60% es usado para la industria de fertilizantes. o Un gran numero de productos industriales modernos utilizan acido sulfurico en alguna etapa de su manufactura. El acido sulfurico es un producto de usos multiples pues por su bajo precio se emplea como agente secante, acidificante, hidrolizante, polimerizante, neutralizante, deshidratante, oxidante, absorvente, lixiviante, catalitico y como reactivo en la industria petro-quimico y quimica inorganica. o Los creditos por la venta de acido influyen positivamente en el flujo de caja neto de las fundiciones y ocasionalmente podrian compensar parcialmente fluctuaciones negativas en los precios del cobre, plomo y zinc. Otros productos alternativos al Acido Sulfurico a) Yeso El proceso requiere gases con baja concentracion de SO(2) (de 2 a 3%), lo que haria necesario la dilucion de los gases de alta concentracion que se producen al aplicar nuevas tecnologias de fundicion. Se preve ademas la produccion de una gran cantidad de yeso con minimo o cero aporte a los ingresos de las fundiciones debido a las limitaciones existentes en el mercado. b) Sulfato de Amonio (Proceso Marino) Tecnicamente es posible producir este material fertilizante nitrogenado de gran demanda en las zonas agricolas del valle del Mantaro, Tarma y Chanchamayo, proximas a La Oroya. Sin embargo no existen en las cercanias plantas productoras de amoniaco en gran escala, lo que haria necesario traerlo de lugares alejados, lo que encareceria el precio del producto. c) Azufre Elemental El proceso requiere gases con concentracion de SO(2) entre 75 a 80%, uso de oxigeno y grandes cantidades de coque o combustibles hidrocarbonados. Ademas tiene alto costo energetico y por ser un producto facilmente inflamable exige medidas de seguridad especiales para evitar incendios. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 158. - -------------------------------------------------------------------------------- d) SO(2) liquido Igualmente requiere de concentraciones altas de SO(2) en los gases (sobre el 60%), su transporte en tanques presurizados es costoso y el mercado es muy restringido. 3.2. Mercado para el Acido Sulfurico: Consumo en Centromin Peru S.A. El consumo interno de acido sulfurico es de 16 100 t/ano. Mercado Nacional Centromin Peru S.A. suministra al mercado nacional 20 000 t/ano de H(2)S0(4) de 98,5% y 6 800 t/ano de oleum con 24% de SO(3) libre. Mercado Potencial en Chile El mercado potencial para el acido sulfurico que produciria el Complejo Metalurgico La Oroya, se concentra en la actividad minera del norte de Chile tanto por su ubicacion, como por el gran volumen de la demanda. El incremento de la demanda se origina por la futura explotacion via lixiviacion acida de grandes yacimientos de minerales oxidados de alta ley encadenada al proceso de SX-EW de bajo costo operativo y simple manejo y control ambientales. Los analisis del mercado de acido sulfurico realizados por la Comision Chilena del Cobre (Cochilco), a partir de 1997, el mercado chileno tendria un deficit anual de 1 200,000 t de acido y se estima que para los anos 1 998 - 2 000 la demanda anual bordearia las 4 300,000 de t, teniendo en consideracion la entrada en operacion de importantes proyectos de lixiviacion tales como: Zaldivar, El Abra, Rodomiro Tomic, Collahuasi (demanda 200 000 t/a de acido), Tesoro y Leonor (demanda 100 000 t/a de acido), Lomas y Bayas (demanda 100 000 t/a de acidos), Damiana de la Div. El Salvador (demanda 275 000 t/a de acido), Vanadio y Andacollo (demanda 140 000 t/a de acido) entre otros. (Revista Mineria Chile No. 169 de julio de 1995). Mercado Potencial en el Peru La politica que impulsa el Gobierno en favor de la industria y la privatizacion, hacen prever el desarrollo a mediano plazo de la industria de fertilizantes luego de la privatizacion de los yacimientos de roca fosforica en Bayovar, industria que constituira un nuevo mercado para el acido sulfurico. Por otra parte, en los proximos diez anos en el Peru se estima entraran en produccion yacimientos de cobre que consumiran acido sulfurico tales como: Toromocho, Antamina, La Granja, Cyprus, Cerro Verde y Magma Copper Tintaya incrementara su reserva de minerales oxidados de Cu de 14B de libras en 1 996 a 24B de lb para el ano 2 000 conviritendose en un gran consumidor de acido (E&MJ enero 1 996 "Magma puts the pedal to the metal"). PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 159. - ----------------------------------------------------------------------------- 3.3 Del Proyecto 3.3.1 Introduccion La capacidad de la plantas de acido sulfurico esta estimada sobre la base de una produccion anual de 70 000 t/Cu, 100 000 t/Pb y 70 000 t/Zn refinados. Este proyecto esta basado en las consideraciones emitidas por el estudio de prefactibilidad desarrollado por Kilborn SNC-Lavalin Europ "Offgas and dust collection prefeasibility study of the environmental aspects of copper, zinc and lead smelter of La Oroya". Modernizacion con nuevas tecnologias El proyecto exige la ejecucion de una etapa previa de modernizacion de los tres circuitos cuyo detalle se condensa como sigue: a) En Fundicion de Cobre Un nuevo tostador para concentrados sucios ubicado sobre el reverbero oxyfuel en reemplazo de los ocho existentes, un secador y convertidor modificado El Teniente, seleccionado por su flexibilidad y versatilidad para adecuarse a diferentes condiciones de operacion y diversas caracteristicas mineralogicas de los concentrados, bajo costo de inversion, equipo de alta productividad, bajo costo de operacion y alto contenido de SO(2) en los gases generados. El ingreso de azufre y la concentracion de SO(2) en las emisiones gaseosas obtenidas luego de la modernizacion serian: Azufre procesado, 79 283 t/a (equivalentes a 235 000 t/a de acido sulfurico). Concentracion de SO(2) de 4,9% (del reverbero oxy-fuel y nuevo tostador). Concentracion de SO(2) de 12 a 16% (de los convertidores PS y CMT). b) En Fundicion de Plomo Una linea de proceso Ausmelt en reemplazo de las actuales plantas de aglomeracion y hornos de plomo, que permitira procesar directamente los concentrados y materiales secundarios de plomo con ingreso de azufre de 45 693 t/a (equivalentes a 135 000 t/a de acido sulfurico), y salida de gases con una concentracion de SO(2) entre 10 a 15% c) En el Circuitode Zinc Instalacion de un nuevo tostador de lecho turbulento (T.L.R.) en reemplazo del actual T.L.R. y los 3 tostadores de cama fluida (F.B.R.) existentes, lo que permitiria un ingreso de azufre de 45 693 t/a (equivalente a 135 000 t/a de acido sulfurico) y salida de gases con una concentracion de 6% de SO(2). PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 160. - -------------------------------------------------------------------------------- 3.3.2 Descripcion del Proyecto y Ubicacion de las Instalaciones El proyecto incluye la instalacion de dos nuevas plantas para produccion de acido sulfurico de doble absorcion y doble contacto para optimizar la conversion de SO(2) a SO(3). Estas unidades deben operar con una eficiencia minima de 95% y deben fijar como minimo el 83% del S0(2) generado en los tres circuitos. a) Planta de Acido Sulfurico No. 1 con capacidad de 235 000 t/ano (Circuito de Cobre) Incluye una infraestructura industrial para producir 235 000 t/a de acido sulfurico procesando los gases generados en la Fundicion de Cobre (convertidores PS, convertidor modificado El Teniente, nuevo tostador para concentrados sucios y actual reverbero oxy-fuel). Los gases de los convertidores PS y CMT luego de ser captados por las campanas colectoras, se conducen a las camaras de enfriamiento evaporativo (una por cada convertidor) desde donde mediante un ducto de alta velocidad ingresan al precipitador electrostatico caliente para recuperar los polvos y desde aqui pasar al sistema de lavado de gases para remover el arsenico y otras impurezas por medio de una torre de lavado por acido al 50%, scrubbers, ciclones, torre de enfriamiento y etapas de precipitacion electrostatica humeda (proceso Boliden). Los efluentes liquidos (acido gastado con arsenico y otras impurezas), seran neutralizados en una planta de tratamiento y los polvos recuperados recircularan al circuito de plomo. Los gases originados en el nuevo tostador de concentrados sucios y los del reverbero oxy-fuel luego de pasar por una caldera de recuperacion de calor siguen su tratamiento segun el proceso Boliden. Los gases libres ya de polvo e impurezas se alimentan en operacion normal a la planta de acido sulfurico pudiendo desviarse la corriente gaseosa hacia la chimenea principal en caso de mal funcionamiento de la planta de acido y/o emergencias. b) Planta de Acido Sulfurico No. 2 con capacidad de 270 000 t/ano (Circuito de Plomo/Circuito de Zinc) Incluye una infraestructura industrial para producir 270 000 t/a de acido sulfurico que procesara los gases provenientes de la fundicion de plomo (reactor Ausmelt) y del circuito de Zinc (nuevo T.L.R.). Los gases provenientes del reactor Ausmelt seguiran el tratamiento descrito para los gases de cobre. Los gases del tostador T.L.R. para concentrados de zinc luego de pasar por una caldera de recuperacion de calor se alimentan a los ciclones, al precipitador electrostatico caliente, al sistema de lavado, a los precipitadores electrostaticos humedos y torres de secado, para finalmente ingresar a la planta de acido. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 161. - -------------------------------------------------------------------------------- Los modulos de acido sulfurico estaran ubicados preferentemente en areas muy proximas a las plantas generadoras de SO(2). Asi, la planta de acido No. 1 se construira en el area adyacente al reverbero oxy-fuel y convertidores y la planta de acido No. 2 se construira en el area adyacente a la planta de acido existente. 4. RESULTADOS DE LA MITIGACION 4.1 Nuevas Emisiones por la Chimenea Como resultado de la implementacion de nuevas tecnologias y de las nuevas plantas de acido el balance de azufre en el complejo metalurgico de La Oroya preve una fijacion de 89,35% del azufre ingresado a los procesos, como sigue: - -------------------------------------------------------------------------------- Ingreso ton de S % - -------------------------------------------------------------------------------- Concentrados de Cobre 85 937 45,65 - -------------------------------------------------------------------------------- Concentrados de Plomo 42 577 22,62 - -------------------------------------------------------------------------------- Concentrados de Zinc 48 012 25,50 - -------------------------------------------------------------------------------- Fundentes para Cobre 5 773 3,07 - -------------------------------------------------------------------------------- Fundentes para Plomo 1 050 0,56 - -------------------------------------------------------------------------------- Otros (*) 4 912 2,61 - -------------------------------------------------------------------------------- Total ingreso 188 261 100,00 (515 t/dia de SO(2)) - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Salidas (fijado) ton de S % (respecto al ingreso) - -------------------------------------------------------------------------------- Acido sulfurico 162 988 86,58 - -------------------------------------------------------------------------------- Escoria de Cobre 2 414 1,28 - -------------------------------------------------------------------------------- Escoria de Plomo 177 0,09 - -------------------------------------------------------------------------------- Concentrados Zn/Ag 522 0,28 - -------------------------------------------------------------------------------- Efluentes liquidos 1 106 0,59 - -------------------------------------------------------------------------------- Bisulfito de Na 66 0,04 - -------------------------------------------------------------------------------- Otros (*) 946 0,50 - -------------------------------------------------------------------------------- Total salidas (fijado) 168 219 89,35 - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Perdida en la chimenea 20 042 10,65 y emisiones fugitivas (110 t/dia de SO(2)) respec. ingreso) - -------------------------------------------------------------------------------- (*) Esponjas de Fe, escorias de Sb, Polvos Cottrell Central, Tostado, mata soda, speiss.

No 315-96-EM/VMM. 4.4 Calidad del aire La concentracion de anhidrido sulfuroso diaria en el medio ambiente sera menor a 572 mg/m3. Las particulas en suspension estaran por debajo de 350 mg/m3, la concentracion mensual de Pb sera de 1,5 mg/m3 como maximo y la concentracion de arsenico por dia, menor a 6 mg/m3, cumpliendo asi las disposiciones del Anexo 3 de la R.M. No 315-96-EM/VMM. 5.

EVALUACION DEL IMPACTO 1.1 Gases fugitivos de la destilacion del carbon durante las descargas de los hornos de coque Actualmente, cuando se abren las compuertas de los hornos para descargar el coque producido y alimentar el carbon, se esta evacuando al ambiente 23 800 m^3/d de gases, producto de la destilacion incompleta del carbon. Anos atras el volumen de estos gases era 32 700 m^3/d. La tabla Nro. 1 condensa la informacion operativa de la Planta de Coque: TABLA Nro.1

Las evaluaciones ambientales realizadas en el techo de los hornos de coque, indican que los gases de la destilacion incompleta del carbon durante el proceso de coquificacion, se diluyen rapidamente en el ambiente. La tabla Nro. 2 registra la composicion de estos gases fugitivos que se presentan durante la descarga de coque y carga de carbon. De igual manera se aprecia que los contaminantes plomo y arsenico, registran concentraciones de 0,018 y 0,012 micrograma/m^3 respectivamente, menores a los niveles maximos permisibles. TABLA Nro. 2

A estas altas temperaturas, la fase gaseosa, producto de la destilacion del carbon esta formada por hidrocarburos. Este fluido pasa por colectores y lavadores de gases, en donde con ayuda de agua se separa del alquitran dejandolo limpio, lo que a una temperatura final de 45 (degrees)C se inyecta a los quemadores de los hornos para ser usado como combustible gaseoso mezclado con el aire precalentado. Los gases producidos en el proceso de coquificacion estan constituidos principalmente de hidrogeno y metano, ademas de nitrogeno, propany y sulfuro de hidregeno en menor cantidad. Es necesario senalar que, el grupo de los fenoles e hidrocarburos pesados van a formar el alquitran de hulla el cual es transportado hasta los hornos de reverbero de la Fundicion de Cobre para ser usado como combustible. La composicion tipica de los gases de la destilacion del carbon que se recicla a los mismos hornos de coque, se registra en la siguiente tabla Nro. 4: TABLA Nro. 4 (Porcentaje en volumen del gas reciclado) -------------------------------------------------------------------------- H(2) CH(4) N(2) C(2)H(6) CO(2) H(2)S O(2) C(3)H(8) CO -------------------------------------------------------------------------- 55,9 19,7 13,6 3,6 1,4 0,8 0,6 1,5 2,9 -------------------------------------------------------------------------- 2. ALTERNATIVAS DE MITIGACION Los hornos Curran Knowles de coquificacion en Centromin, son hornos de tipo convencional con recuperacion de subproductos, diseno que en los EE.UU. de N.A. funciona desde el ano 1941. En estos hornos el carbon se carga y acomoda sobre el piso refractario a lo largo y ancho de cada horno para formar una carga de 2,45 mx 9,75 m con alturas hasta de 0,32 m. La produccion de coque metalurgico en la Fundicion de Plomo data desde el ano 1944. Existe escasez de carbon nacional de calidad bituminoso coquificable y aglomerable para PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 171. - -------------------------------------------------------------------------------- producir coque poroso, resistente, con buen poder calorifico y con el menor contenido de cenizas para usarse como combustible y reductor con sinter de plomo en las columnas de los hornos de manga de la fundicion. Hasta fines del ano 1971, se estuvo utilizando carbon nacional (Goyllar) con alto contenido de cenizas (20%), el cual con un ciclo de coquificacion muy corto (14 horas/horno), producia casi 33 000 m^3/d de gases de destilacion de carbon, cuya descarga al medio ambiente era muy procupante. Desde 1988 se procesaron carbones de Colombia mezclados con el carbon Goyllar hasta mayo de 1993. El carbon nacional degeneraba la calidad de produccion de coque a la vez que no permitia mitigar la descarga de gases destilados al medio ambiente. Con el carbon Prodeco de Colombia; cuya composicion promedio es de 23%:MV, 69%:CF y 8% de-cenizas; se impulsa desde 1988 el aumento de la capacidad de produccion de la Planta de Coque y la disminucion de fuga de gases destilados al ambiente durante las descargas. Este Proyecto tiene como objectivo principal mitigar la emanacion de gases fugitivos y polvos que se generan en los hornos de coquificacion en los momentos de las descargas de coque producido. Las condiciones operativas al presente se grafica en el diagrama siguiente: [GRAPHIC OMITTED] Como medidas de mitigacion para la Planta de Coque, en cuanto a la emanacion de gases fugitivos producto de la destilacion del carbon, se plantean las siguientes alternativas: 2.1. Alternativa seleccionada 2.1.1. Operar los hornos con ciclos de coquificacion de 24 o 26 horas. Tomando en cuenta el posicionamiento y la dependencia del mercado de coque metalurgico en el futuro, se propone mitigar el problema de los gases fugitivos mencionado, operando los hornos de coquificacion con ciclos de 24 a 26 horas, supliendo la diferencia de cantidad de coque mediante la importacion del mismo. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 172. - -------------------------------------------------------------------------------- El carbon alimentado (actualmente 5,6 t/horno), cumple su proceso de coquificacion empezando desde el secado, plasticidad, hinchamiento, sigue la grafitacion a formacion de coque y la contraccion del mismo, de aspecto poroso, estable, duro. aglomerado y resistente para su trabajo en las columnas de los hornos de manga conjuntamente con el sinter. Normalmente este proceso de coquificacion debe desarrollarse en un tiempo minimo de 24 o 26 horas a fin de completar su ciclo. Al tomarse menos tiempo, como se hace actualmente, con 18 o 20 horas (antes 14), se esta permitiendo a que los gases y volatiles del proceso que aun permanecen en el horno, se expandan al ambiente al momento de abrir el horno para descargar el coque. Por ello, una de las alternativas para mitigar la evacuacion de gases fugitivos al medio ambiente es aumentar el tiempo de proceso entre 4 y 6 horas, es decir operar con ciclos de 24 o 26 horas. Con esto habra un deficit de coque grueso para los hornos de plomo, por lo que de acuerdo a calculos de consumo, el regimen de adquisicion de carbon y coque anualmente seria: o Compra de 41 000 t de carbon coquificable para producir 27 000 t de coque grueso. o Compra de 8 200 t de coque grueso de coqueria de terceros. 2.2. Otras alternativas 2.2.1. Instalacion de Sistemas de Ventilacion (SVEL). La instalacion de Sistemas de Ventilacion para captar 23 800 m^3 de gases diariamente, implicaria la instalacion de ducterias de fierro resistente a altas temperaturas (650 (degrees)C), valvulas especiales, scrubber, ventiladora, pozas de sedimentacion, la instalacion de equipos adicionales como tolvas enfriadoras selladas con chorros de agua (quenching car), carros de transporte con encerramientos, sistemas de ducterias con la que se mantendria la produccion actual, con ciclos de 18 a 20 horas y evitar la compra de coque extra. Obviamente, el gran problema de esta alternativa es el costo permanente de mantenimiento de equipos y el poco espacio disponible de la Pta. de Coque. 2.2.2. Sustituir totalmente la compra de carbon por coque metalurgico En 1985 y 1993 se han evaluado las operaciones de los hornos de plomo con coque de Japon (Mitsubishi) y coque de Colombia (Carbones y Minerales). Los resultados no han sido totalmente satisfactorios; el primero porque el coque fue de calidad siderurgica y el segundo debido a que el valor de compra frente al coque preparado en nuestra Planta, fue mayor en casi US $ 45 por ton. puesto en La Oroya. Sin embargo es posible buscar otros proveedores de coque a fin de "cerrar" la Planta y operar la Fundicion solo con el manejo de la compra de coque de terceros como hace la Empresa Penoles de Mexico, sin embargo ello significaria un costo promedio anual de 7,5 millones de U.S.$ frente al actual de 5,5 milliones de U.S.$ aproximadamente. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 173. - -------------------------------------------------------------------------------- 2.2.3. Plantear a un proveedor de carbon, fabrique coque cerca a La Oroya. Plantea invitar e inducir a terceros, la produccion y suministro de coque dentro de la region, mediante contratos o convenios. 2.2.4. Construir Coqueria de Punta (Verticales de encerramiento total) sin recuperacion de subproductos. Solicitar la construccion de hornos de diseno vertical con transmision de calor lateral, patentes OTTO HOFMAN o KOPPERS-BECKER de los EE.UU. de N.A o KEMBLA COAL AND COKE de Australia. 2.3. Cronograma de ejecucion de la alternativa seleccionada. Operar la Planta de Coque con ciclos del proceso de coquificacion de 24 o 26 horas, depende de la disponibilidad de coque para los hornos de manga. Por ello, el cornograma de ejecucion del presente proyecto, esta dirigido principalmente a la compra de coque metalurgico al granel, en base al siguiente programa: TABLE Nro. 5

3. RESULTADO DE LA MITIGACION 3.1. Se prevee la descontaminacion ambiental conforme se grafica en el siguiente diagrama: [GRAPHIC OMITTED] PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 174. - -------------------------------------------------------------------------------- Para lograr este resultado se estima que habra un costo adicional anual de US $ 670 000 aproximadamente, lo que estaria justificado desde el punto de vista ecologico y desarrollo sustentable. La evacuacion de los gases fugitivos sera disminuido al minimo (80 m^3/d) puesto que se estara trabajando los hornos de coquificacion con ciclos mayores a los actuales, permitiendo el procesamiento completo de carbon a coque. Por lo tanto, los gases fugitivos que actualmente se descargan al ambiente se captaran y lavaran, reciclando a los quemadores de los hornos para quemarlos con el aire en los ductos de llama, combustion, a fin de mantener los pisos de los hornos con temperaturas de 1 350 (degrees)C promedio.

3.2 Emision de Particulas Con la evacuacion de gases de 80 m^3/d (4m^3/descarga), se asegura que la Emision de Particulas al medio ambiente sea menor del nivel maximo permisible (100 mg/m^3), requerido por el Ministerio de Energia y Minas de acuerdo a la Resolucion Ministerial Nro. 315-96-EM/VMM. Ademas, las emisiones de As y Pb en estos gases son practicamente nulas, adecuandose a los articulos 4to. y 5to. de la mencionada Resolucion. 3.3 Calidad del Aire Las concentraciones de Pb: 0,018 micrograma/m^3 y As 0,012 micrograma/m^3 en las nuevas emisiones al medio ambiente, estaran muy por debajo de los NMP que norma la calidad de aire (anexo 3) de la Resolucion Ministerial 315-96.-EM/VMM.

OBJETIVO: Los objectivos principales del proyecto son, reduccion del consumo de petroleo residual No 6 en la Planta de Residous Anodicos mediante el uso de aire enriquecido con oxigeno para la combustion y eliminacion de los gases nitrosos generados por el nitrato de sodio, reactivo oxidante usado en la ultima etapa del proceso de copelacion 2. EVALUACION DEL IMPACTO AMBIENTAL: La planta de Residous Anodicos, trata los lodos anodicos de las Refinerias de Cobre y Plomo que constituyen la materia prima para la obstencion de dore ,bismuto ,selenio y telurio. Estos lodos anodicos son procesados por las etapas: fusion, conversion y copelacion para obtener dore. En el proceso de copelacion, que se realiza en batch y con una duracion aproximada de 7 dias, se tiene una ultima etapa que es la de "lavado" de dore con nitrato de sodio , esta etapa dura 24 horas y es donde se generan los gases nitrosos contaminantes del medio ambiente. (Diagrama No 1). El consumo promedio de nitrato de sodio es de 160 - 180 t/ano, las posibles reacciones a realizarse son: 1. NaNO(3) + (delta) -> Na(2)O + NO(2) + 1/2 O(2) Na(2)CO(3) + (delta) -> Na(2)O + CO(2) 2. (Se-Ag-Au-Cu-Te)(x)/Mata + 1/2 O(2) + xNa(2)CO(3) + xNaNO(3)-> xCO(2) + xNO(2) + Na(2)TeO(3) + Na(2)SeO(3) + TeO(2)CuO(2) + (Ag-Au/Dore)
En las reacciones anteriores el oxidante es el oxigeno liberado al reducirse el nitrato de sodio a NO(2), el carbonato permite una accion mas prolongada de este oxigeno. 3. ALTERNATIVAS PARA LA MITIGACION: 3.1 Uso de oxigeno gaseoso en el Proceso de Copelacion: El proceso consiste en reemplazar el uso de nitrato de sodio por oxigeno gaseoso en el proceso de copelacion con lo que se estaria eliminando la generacion de gases nitrosos que contaminan el medio ambiente. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 176. - -------------------------------------------------------------------------------- 4. DESCRIPCION DEL PROCESO: El proceso contempla reemplazar el nitrato de sodio por la inyeccion de oxigeno gaseoso al seno del bano metalico a traves de una lanza y/o quemador especial, simulando a la Tecnologia Ausmelt. o Resultados de la mitigacion: Eliminado el uso de nitrato de sodio en la ultima etapa del proceso de copelacion, no existiran las emisiones de gases nitroses al ambiente. 5. MONTO DE LA INVERSION El costo estimado para la ejecucion de este proyecto es de US$ 391 000. 6. CRONOGRAMA Actualmente el proyecto se encuentra en ejecucion, estando por concluirse la primers etapa, es decir la de uso de oxigena en la combustion de petroleo residual No 6. La segunda etapa que comprende el empleo de oxigeno en el proceso de copelacion, deberia quedar concluida el proximo ano.

OBJECTIVO: Delimitar y rehabilitar el area afectada por los humos, considerando la flora, fauna, suelos, agua, etc., existentes en la zona. De igual manera, establecer puntos de control sobre la calidad de aire, suelos, que permita tomar acciones correctivas. La rehabilitacion del Area afectada contempla 4 etapas: o Cultivo de Cobertura o Control de Carcavas por diques o Cultivo y plantacion de terrazas o Modificacion de taludes 1.1 Estudio del Area Afectada por los Humos. (a) Diagnostico Este ultimo periodo, el area afectada no ha tenido una vasta recuperacion como el que se tuvo en el periodo 1941 - 1971. (de 14 190 Ha. a 4 170 Ha.) registrandose de esta ultima fecha a Enero de 1996, una extension aun afectada de 3 829 Ha. La epoca de mayor recuperacion de suelos, corresponde al de la implementacion de precipitadores electrostaticos y mejoras de proceso, los cuales tuvieron una respuesta rapida, dentro de los limites de su radio de accion. Las recuperaciones posteriores a 1971, ya no han tenido efectos muy notorios, al sobrepasar los limites senalados. Desde luego, no se puede ignorar, que la presencia de vegetales en el nucleo mismo del area afectada, va mostrando una lenta recuperacion espontanea y mucho mas notoria en las areas donde se han hecho trabajos de revgetacion y forestacion dirigidas; todo ello, es un testimonio de que la recuperacion va avanzando lentamente, pero, sin detenerse. La recuperacion en el area de Huaynacancha vieja es notoria respecto a 1971, ya que en aquella etapa no se podia apreciar verdor alguno en la zona; hoy, se puede ver un panaroma mas agradable, con manchones de vegetacion tupida, y otras areas extensas, con recuperacion muy dispersa, que posiblemente cubre una extension similar a la cubierte por los manchones. Por otro lado, la presencia de aves y animales silvestres, como los jilgueros, gorriones, zorzales, patos y huachuas y manadas de vicunas, nos inducen a pensar, que los humos evacuados, ya no fueron tan nocivos como lo fue en el pasado. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 179. - -------------------------------------------------------------------------------- b) Situacion ambiental del ecosistema y recursos naturales del area afectada En el recorrido de campo y durante el trabajo de delimitacion se aprovecho para observar in situ los danos ocasionados sobre la cobertura original del suelo, la formacion de las carcavas, la vegetacion que resistio a la accion toxico de los humos de la fundicion, asi como la vegetacion recuperada en forma espontanea y tambien para la recoleccion de muestras de suelos, agua y observar la fauna existente. c) Inventario y evaluacion de la cobertura vegetal en zona afectada. Esta operacion comprende la identificacion de las especies existentes en el area afectada. Las especies vegetales encontradas en la zona de estudio comprende especies herbaceas, arbustivas y arboreas; entre las primeras se encontro especies silvestres desarrollandose espontaneamente y otras cultivadas, como la flores. Entre las arbustivas tambien se encuentran especies silvestres y cultivadas. Las especies arboreas en su totalidad son especies sembradas, algunas propias de la altitud y clima de la zona de estudio y otras que son importadas de otras zonas y adaptadas al area de estudio. Especies herbaceas silvestres: Achicoria, llanten, kikuyo, mullaca, yanta, menta, amor seco, etc. Especies Herbaceas cultivadas: Flores como la calendula, clavel, mastuerzo, pensamiento, margarita, francesita, copa de oro. Especies arbustivas silvestres: Chilca. Especies arbustivas cultivadas: Retama, retama americana, agave(maguey). Especies arboreas silvestres: Depredadas. Especies arboreas cultivadas: Kolle (Buddeleya coriacea), quinual (Polyle-pis racemosa), capuli (Prunus capolinus), cipres (Cupressus Sp.). En lo referente a PASTOS, Se determina las especies y las asociaciones de pastos naturales, su composicion y talvez la soportabilidad en las areas que muestran recuperacion. En la zona en estudio, la recuperacion de este tipo de vegetacion es aun incipiente, de modo que no tiene capacidad para el pastoreo de ganado, a lo mas esta albergando tres tropillas de vicunas, que por silvetres, pastan esporadicamente en el lugar. Se ha podido identificar especies como el Kikuyo, Festuca sp., que aun no muestran una recuperacion franca. En cuanto a FORESTALES, Comprene la identificacion de especies en bosque naturales, si aun existen, que correspondan al piso ecologico en el se halla el area en estudio, comprendiendo especies nativas e importadas. En el area afectada no se ha encontrado ningun ejemplar que este creciendo en froma espontanea. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 180. - -------------------------------------------------------------------------------- Se han identificado arboles cultivados, que comprenden especies nativas de la zona como el Kolle y el Quinual, que no solamente desaparecieron por efecto de los humos de la fundicion, sino tambien por la depredacion de que fueron objeto por parte de la poblacion. Ademas de los anteriores hay especies importados de otros lugares y que han sido adaptadas a la zona, como el Cipres, Capuli, Quishuar, etc. que soportan bien las condiciones ecologicas reinantes en la zona de estudio. Existiendo en la actualidad bastante interes por parte de las entidades ediles y de Centromin Peru S.A. por la forestacion. En lo concerniente a FAUNA, Comprende un inventario e identification de las especies, debiendo considerarse la fauna silvestre y la domestica. Dentro de la primera hemos podido encontrar tres tropillas de vicunas que apacentan y abrevan dentro del area de afectacion grave. Del mismo modo se ha observado la presencia de patos silvestres y un ejemplar de huachua, que acuden a la pequena laguna que se halla ubicada en la parte media del valle de Huaynacancha. No se puede dejar de mencionar la prescencia de especies de pajaros como zorzales y jilgueros. Con fines de seguridad destaca la crianza de perros y con fines de adorno y compania, la de los gatos, aparte de animales silvestres como ratas y ratones. Todas las especies animales mencionadas parecen no ser afectadas por los humos de la Fundicion. d) objetivo El proyecto de delimitacion del area afectada, considera ademas de determinar la extension aun danada, realizar estudios que permitan establecer el estado en que se encuentra, en lo que se refiere a flora, fauna, suelos, agua atc. asi como establecer puntos de control de la calidad del aire y calidad de la tierra, que suministraran informacion valiosa que permitira plantear las acciones a tomar para la rehabilitacion del area en estudio, asi como rehabilitar las zonas que se presten a este fin. e) Alternativas de Solucion Si la rehabilitacion se hace por medio de cultivos, solo se puede tener efecto con el incremento de la materia organica; pero, logrado esto, se produciran los demas efectos quimicos y fisicos. Ademas es necesario usar diversas tecnicas que impidan seguir con el deterioro de los terrenos y por el contrario ayudar al proceso de recuperacion espontanea observada en la zona de Huaynacancha, por medio de la construccion de diques, modificacion de carcavas y construccion de terrazas. Hay extensas areas, casi llanuras, en algunas de las cuales se pueden hacer trabajos con miras a establecer cobertura vegetal, experimentalmente, y de repente ya en forma definitiva. Hay otras areas donde se puede proceder a roturar, a modo de facilitar la retencion y/o obsorcion de las aguas pluviales, ademas de adecuar el suelo para el albergue o anclaje de las semillas producidas por las plantas adultas PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 181. - -------------------------------------------------------------------------------- de los alrededores, que son dispersadas por el viento. Esto ultimo, basado en lo observado en diferentes zonas donde hubo movimiento de tierras y su consecuente cobertura vegetal espontanea. Tambien se debe proceder a arborizar, no solo los taludes y fondo de las carcavas, sino tambien las suaves laderas que abundan en la zona de Huaynacancha; para ello, se deberan utilizar plantones de doble repique, que son mas desarrollados y fuertes, que garantizan una segura supervivencia. Es posible evitar que continuen formandose nuevas carcavas y crezcan las existentes por medio de trabajos adecuados ya descritos en parrafos anteriores, poblando la cuenca de las carcavas grandes con vegetacion herbacea, arbustiva y arborea; sean estas, especies nativas y/o importadas, sean utiles o no, el objeto es cubrir las areas desnudas y evitar continue la erosion. En las laderas existentes frente a la Fundicion es posible recuperar su cobertura vegetal por cultivos o por plantacion de especies arboreas, ya que el analisis de su suelo es favorable en su caracterizacion y en su composicion. Todo lo indicado requerira de tiempo e inversion, ver Tabla No 5.1, "Cronograma de Inversiones del proyecto de recuperacion del Area Afectada por los Humos". f) Analisis tecnico-economico de viabilidad Elaboracion del plan de recuperacion El plan estara destinado a recuperar las areas que presentan posibilidades de logro, que estan dadas por las caracteristicas de suelo, morfologia de la superficie y tal vez en algunos casos por las posibilidad de riego, en base a las fuentes de agua ubicadas en area de estudio. La altitud y el clima, asociados a la pobreza del suelo del area por recuperar, condicionan un medio bastante agresivo para el desarrollo de la flora, limitando la diversidad de epecies, que son numerosas en otras areas de igual piso ecologico, pero, de mejores suelo. Posiblemente las especies arbustivas asi como las herbaceas, sean estas nativas o adaptadas, las que mejores resultados den en el plan de recuperacion de la cobertura vegetal, dirigida a eliminar o morigerar la erosion que sufren actualmente los terrenos del area en estudio, por accion de las aguas pluviales y el viento, que actuan directamente sobre el suelo denudado, mejorando al mismo tiempo el medio ambiente. Las condiciones climaticas y de suelos anotados no son aptas para el establecimiento de bosques maderables, pero si, para el establecimiento de bosques en bloques a base de especies arboreas nativas como el kolle, quinual y de especies importadas como el capuli, cipres, quishuar, que han dado muestras de una buena adaptacion al medio. Por lo observado en nuestro recorrido de campo, a nuestro parecer, la zona que forma el valle de Huaynacancha, donde se ubico el pueblo del mismo nombre, es el area donde se pueden hacer trabajos conduncentes a su recuperacion, en favor de esta idea se puede mencionar su pendiente moderada, la ausencia de terrenos roco- PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 182. - -------------------------------------------------------------------------------- sos, el sub suelo no muy duro y la posibilidad de mecanizar tanto la roturacion del suelo de la llanura, como la construccion de terrazas, con el fin de establecer cultivos que amplien o mejoren la cobertura vegetal espontanea que se observa en la parte baja de esta zona; asi como tambien hacer trabajos de recuperacion de cobertura con especies arboreas propias de la region asi como con especies adaptadas. Del mismo modo, pensamos que es necesario y factible de hacerlo, el evitar de que las carcavas existentes se profundicen y se amplien mas, lo cual se alcanzara con trabajos adecuados que comprenden el relleno o colmataje de las carcavas en sus cabeceras. Ademas, en las partes mas amplias de las carcavas se puede modificar el perfil de los taludes para evitar mayor deslizamiento de tierra de los bordes y facilitar la cobertura de los mismos con vegetacion herbacea, arbustiva y arborea. Complementando estas acciones tambien se puede en el uso de terrazas o terraplenes para cortar la velocidad de las aguas de escorrentia que son las que dan origen a la erosion de los suelos y consecuente formacion de los carcavas. Se manifesto, que son varias las acciones a las que se puede echar mano a fin de mejorar y/o ayudar a la recuperacion de la cobertura vegetal en el area de estudio, entre los que mencionamos: Rehabilitacion y Conservacion de Suelos por Cultivos. Los suelos involucrados dentro del area de danos graves producidos por los humos de la fundicion, al estar denudados desde hace anos, han sufrido la accion erosiva y lavado de los elementos minerales por accion de las lluvias estacionales que se precipitan todos los anos, esto obliga a pensar que la rehabilitacion de los terrenos afectados va a ser un proceso lento y costosos (remitirse a la Tabla No. 5.1A y los planos Nos. 1-580-00-300 y 1-559-01-2008). Si la rehabilitacion se hace por medio de cultivos, solo puede tener efecto con el incremento de la materia organica; pero, logrado esto, se produciran los demas efectos quimicos y fisicos. El contenido mineral del suelo no aumentara con el cultivo, pero puede conservarse lo que aun existe, al impedir la cobertura vegetal, que siga el desgaste por lavado y erosion del suelo. Es pues preciso recurrir a una cobertura permanente del suelo o pradera para obtener una verdadera rehabilitacion del suelo. El cesped permanente aumentara la materia organica del suelo particularmente a causa del desarrollo de su sistema radicular. La hierba en buen estado vegetativo aumenta sus raices todos los anos y la descomposicion de las raices viejas aumenta la materia organica, la mayor parte de la cual se conserva en el suelo que se deja de cultivar nuevamente quedando como una pradera. En lo que respecta a la reposicion de los elementos minerales eliminados del suelo por lavado y erosion, estos no pueden ser restaurados por intermedio de las plantas y cultivos, todos los minerales que tienen, provienen del suelo. La cal, fosforo o PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 183. - -------------------------------------------------------------------------------- potasio adicional que la tierra requiere son elementos que habran de ser suministrados por abonamiento con fertilizantes comerciales. Sin embargo, las plantas al restaurar la materia organica, restauran con ella el nitrogeno del suelo. Las leguminosas son las plantas que mejor acumulan el nitrogeno, gran parte del cual extraen del aire. En el caso del area en estudio, la cobertura vegetal que se podria utilizar para la rehabilitacion de los terrenos factibles de recuperar, sobre todo en la parte baja del valle de Huaynacancha, seria mediante el cultivo asociado de gramineas y leguminosas. las cuales deberan ser sembradas al valeo, ya que asi contribuyen mejor a detener la erosion. Las especies vegetales utilizadas con bastante exito en zonas de altitud y candiciones climaticas similares a la zona en estudio son el rye grass y el trebol blanco, especies que ofrecen un macollaje amplio y denso dando una cobertura muy buena al suelo. Para la siembra del cultivo asaciado antes indicado, previamente se deberia proceder al encalado y fertilizacion con estiercol, para asi mejorar las condiciones del suelo que habra de albergar vegetacion permanente, luega de muchos anos de lavado y erosion a que estuva sometido. Es de advertir que el encalada es una operacion onerosa por el volumen de material por anadir y la preparacion del mismo; la cobertura vegetal, en ultimo termino, se encargara de solucionar esta deficiencia. No esta demas indicar, que el establecimiento de la cobertura vegetal con miras a la rehabilitacion, utilizando cultivos, permite tambien a las plantas conservar el suelo hasta el grado en que su cultivo es compatible con una minima remosion durante las operaciones de labranza y en proporcion a su densidad y estabilidad como cobertura vegetal. Se ha observada que en algunas areas, ubicadas dentro de la zona de afectacion grave, en las cuales se hizo movimiento de tierra, el suela removido ha sido casi enteramente cubierto por vegetacion herbacea, principalmente gramineas; creemos que esta recuperacion se debe a que con el movimiento del sueloa, ademas de propiciar una mejor retencion y/o absorcion de las aguas pluviales, se ha acondicionado el terreno para el anclaje de las semillas y la propagacion de estalones, facilitando su germinacion y brotes, respectivamente. Por lo expuesto, ademas de las areas en las que se siembren especies para cobertura, en otras, simplemente se procederia a roturar un tiempo prudencial antes de la estacion de lluvias, para propiciar una recuperacion como la observada en muchas zonas del area afectada. g) Control de carcavas De todoas los dones de ia naturaleza, ninguno es mas indispensable para el hombre que la tierra. Esta mezcla campleja de materia animal, vegetal y minerales, que cu- PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 184. - -------------------------------------------------------------------------------- bre el nuceo rocoso del globo terrestre a profundidades diversas, es una de los cuatro elementos primarios indispensables para la vida. Junta can la luz solar, con el aire y con el agua, la tierra nutre la vida vegetal y sustenta a todoas los seres vivientes. En el caso del area afectada por la accion de los humos de la fundicion, desaparecio la vegetacion nativa, que fungia de cobertura de los suelos, acelerandose el grado de remosion de los suelos, trayendo como consecuencia la esterilidad de los terrenos y luego la formacion de carcavas que cruzan el area del valle de Huaynacancha y los terrenos ubicados frente a la fundicion. Como las carcavas tienden a drenar la humedad del suelo adyacente, las campos se secan can mucha mas rapidez cerca de ellas, y esta resulta en una disminucion del avance de la recuperacion de la cobertura vegetal. A medida que las carcavas aumentaron de tamano se ramificaron sobre el campo, y si no se pone coto a su desarrolla, se tendra que pensar en abandonar todo prayecto de recuperacion. Ya que a medida que las carcavas se extiendan hacia atras y crucen depresiones naturales, se produciran caidas laterales desarrollandose otras carcavas; este praceso de ramificacion puede continuar hasta que una red de carcavas terminen por cubrir todo el valle y haga imposible su control, por los trabajos que hay que hacer y los costos que ellos representan. Por lo expuesto, es necesario echar mano a las diversas tecnicas que impidan seguir con el deterioro de los terrenos y por el contrario ayudar al proceso de recuperacion espantanea observada en la zona de Huaynacancha. h) Construccion de diques A menos que la superficie se proteja pronto con vegetacion o que los canaliculos, inicia de las carcavas, se hagan desaparecer por medio de cultivo u otras acciones, estos continuaran agrandandose con cada lluvia sucesiva. Los canaliculos mas profundos pueden aumentar en tamano y formar carcavas tan grandes que ya no es posible hacerlas desaparecer por los metodos normales de labranza, como ocurre con las carcavas que se ven frente a la fundicion y las existentes en la zona de Huaynacancha. Habra entonces que gastar en mano de obra para rellenar a canstruir diques en el curso de las canaliculos. La construccion de diques en forma escalanada, donde las carcavas aun se manifiestan como pequenos surcos, permitiran su relleno por colmataje de las aguas que corren por los canaliculos, fuertemente cargadas de materias solidas, que pueden depositarse tras el dique y levantar de esta manera el lecho de la carcavas. Este relleno por deposicion a colmataje es facilitado, ademas del dique, que puede hacerse con montones bien campactos de piedras y ramas a traves del fondo de la carcava, por la vegetacion, si hubiese, y otros obsticulos que ayuden a regular la velocidad del agua. Ademas del uso de diques de piedras se puede hacer tambien con mallas y ramas; este tipo de dique se puede hacer en carcavas mas amplias y menos profundas. PAMA COMPLEJO METALURGICO - LAOROYA Capitulo V Pag 185 - -------------------------------------------------------------------------------- i) Modificacion de carcavas Toda carcava, no importa su tamano ni sus condiciones, volvera por lo general a cubrirse de vegetacion con tal que tenga proteccion adecuada y este localizada en una region donde pueda crecer vegetacion. En terrenos afectados, como los observados en el area de graves danos hay varias causas que retrasan la desaparicion de toda huella de erosion. Una de estas causas es el declive de las paredes de las carcavas, mientras no se derrumben, naturalmente, o se modifique las paredes escarpadas por trabajo, y formen una pendiente mas moderada, les es dificil arraigar a las plantas. Por ello, modificar el perfil de los taludes en los tramos en que las carcavas son amplias, permitiran trabajos de recuperacion de la cobertura vegetal que evitara, continue la erosion por accion de las aguas pluviales. En los taludes modificados y preparados para facilitar el anclaje de las semillas llevadas por el viento y para el cultivo y plantacion de especies arboreas, primero apareceran las malezas. Al principio creceran muy lentamente, como hemos podido observar en nuestro recorrido de campo, porque le sera dificil arraigar. Mas tarde en cuanto las primeras plantas hayan mejorado algo el suelo apareceran otras. Tal vez este proceso natural tarde muchos anos en la zona, por la altitud y el clima existente, por si solo muy extremo, pero sera mas rapido donde la humedad sea mayor. Con el tiempo, este proceso natural llegara a cubrir de nuevo la carcava con la vegetacion predominante en la zona, sean arbustos o hierbas. En lo que respecta exclusivamente a detener la erosion en la zona afectada, importa poco usar arboles, arbustos o pastos. Cualquier vegetacion de las clases mencionadas proveera buena proteccion para el suelo, si se consigue establecerla satisfactoriamente. En la zona de estudio, la vegetacion espontanea no es suficiente para contrarrestar la erosion existente, por lo que creemos es necesario recurrir a medios y recursos para establecer la vegetacion artificialmente. Al seleccionar arboles, arbustos o pastos para sembrar en el talud de las carcavas, se dara preferencia a las plantas que sean naturales de la region y propias de terrenos similares. Estas estan ya aclimatadas y por consiguiente tienen mayor probabilidad de subsistir bajo las serias condiciones de crecimiento en las carcavas y el clima reinante en el ambiente. En caso de que no fueran satisfactorias las plantas utiles naturales de la region, se escogeran entonces las especies traidas de otras regiones. La plantacion de las especies nativas como el Kolle, quinual etc. se debe extender a otras areas, plantando en bloques y utilizando plantas de doble repique, de manera que estas ultimas ya tengan una estructura casi lenosa, que asegura su supervivencia y empiece su accion edafica en el suelo de su alrededor. PAMA COMPLEJO METALURGICO - LAOROYA Capitulo V Pag 186 - -------------------------------------------------------------------------------- Esta accion, en el valle de Huaynacancha debe tener exito, toda vez que en forma espontanea y en taludes de fuerte pendiente existe vegetacion mas o menos abundante y bien desarrollada lo que podria atribuirse a la humedad de los taludes y al microclima que se propicia en la hendidura. j) Construccion de terrazas Uno de los mejores metodos que se conocen para detener la erosion en las pendientes es el uso de terrazas. Estas son muy eficaces para corregir las carcavas pequenas, que no sean tan hondas que impidan el trabajo can maquinaria. Tal vez la construccion de terrazas sea dificil y algo costosa en una zona tan afectada por la erosion, sin embargo, es la medida correctiva mas eficaz para pendientes como las existentes en la zona de estudio, especialmente por existir muchas carcavas paralelas en pendientes algo dificiles de cultivar. Las terrazas, consisten en una serie de fajas ilanas o casi llanas, construidas a traves de las pendientes en terrenos escarpados; constituye uno de los medios artificiales mas antiguos para detener la erosion de los suelos, utilizado por muchas centurias en el Peru Antiguo, por la escasez de terrenos de cultivo en las zonas o pisos ecologicos de la sierra con clima favorable. El proposito de las terrazas es recoger o interceptar el agua que corre ladera abajo y retenerlo hasta que infiltre y parte sea absorbido por las plantas que se cultivan en la plataforma. Al construir las terrazas, el borde externo del plano de la terraza debe ser mas alto, con declive hacia la base a fin del talud, el cual es casi vertical. El agua correra a lo largo del banco a distintas velocidades dependiendo del tipo del suelo, longitud de la terraza y desde luego la precipitacion pluvial y la cobertura por el sembrio de especies vegetales de buen macollaje. Sobre las terraplenes se cultivaran especies vegetales que sirvan de cobertura al suelo. Una combinacion muy recomendable para cubrir la plataforma con vegetacion, es el cultivo asociado de ray grass y trebol blanco, ambas especies de frondoso macollaje que ofrecen mayor y mejor cobertura del suelo; por lo general es aconsejable usar mas de una especie en las combinaciones compatibles, ya que los vastagos puros son generalmente vulnerables a influencias perjudiciales, enfermedades y plagas. Previo al sembrio en las plataformas, debera procederse a su encalado y fertilizacion con estiercol de ganado , ello permitira una mejor retencion del agua, mejor desarrollo del cultivo y una buena fructificacion, que al final del periodo vegetativo, permite retener las valiosas semillas que repoblaran el suelo cultivado de la terraza. Al borde de las terrazas a plataformas se pueden plantar arboles para que por enraizamiento no permita el arrastre de los bordes por la lluvia, sirviendo tambien coma corta viento, mejorando el microclima de la terraza cultivada, ya que durante el estiaje impera un clima extremadamente frio.

OBJETIVO: El objetivo principal del proyecto es tratar las soluciones acido-ferrosas que se descargan al rio Yauli y obtener una solucion neutralizada apta para descartar previa recuperacion del niquel, y purificar la solucion raff para obtener un efluente final con contenidos e impurezas por debajo de los niveles maximos permisibles (R.M. No. 011-96-EM/VMM). 2. EVALUACION DEL IMPACTO AMBIENTAL: Para mantener el nivel de impurezas en el electrolito de la Refineria de Cobre, diariamente se extraen del circuito 30 a 40 mil litros, que se transfieren a los neutralizadores, en los cuales por calentamiento con vapor, adicion de chatarra de cobre evaporacion/oxidacion con aire se obtiene una solucion saturada apta para la produccion de sulfato de cobre por cristalizacion al vacio. Los cristales de CuSO(4) se separan por centrifugacion y el agua madre obtenida es parcialmente recirculada a los neutralizadores. El exceso de agua madre se transfiere a un tanque de precipitacion donde una vez calentada con vapor se le adiciona chatarra de fierro para recuperar el cobre en forma de cemento que retorna a la fundicion. La solucion acidaferrosa libre de cobre (11,000 l/dia), es finalmente descargada al Rio Yauli. (Diag. No 1). Los analisis promedio en g/l del agua madre y efluentes que se vierten al rio Yauli, muestran las siguientes caracteristicas: Agua madre: ================================================ H(2)SO(4) Cu Fe As Sb Bi Ni ------------------------------------------------ 130 54 2,5 3,5 ,36 0,12 1,7 ================================================ Efluente: ================================================ pH Cu Fe As Sb Bi Ni ------------------------------------------------ 2 12 0,14 3,5 0,15 0,03 0,17 ================================================ 3. ALTERNATIVAS PARA LA MITIGACION: 3.1 Proceso de Oxidacion - Neutralizacion El proceso consiste en neutralizar el agua madre con chatarra y oxidos de cobre en un medio de agitacion - oxidacion para propiciar la precipitacion de arseniatos ferricos y otras impurezas y obtener una solucion purificada para ser retornada al circuito. Esta alternativa fue desechada por la imposibilidad de controlar el contenido de niquel en la solucion de retorno a la casa tanques, elevada recirculacion de cobre y dificultad de filtracion de los precipitados (arseniatos de Fierro).

INTRODUCCION: Actualmente el agua que se usa para la refrigeracion de los procesos industriales de la Fundicion de La Oroya, es vertida casi integramente al rio Mantaro, a traves de canales abiertos o tuberias que recorren las instalaciones industriales de la Fundicion. Estas aguas de refrigeracion se mezclan en mucho casos, con efluentes domesticos o industriales, incrementandose el volumen de aguas contaminadas. En otros casos las aguas de refrigeracion se contaminan por el solo hecho de pasar por las areas industriales, debido a la presencia de polvo, solidos y gases. Para resolver este problema se ha planteado dos alternativas: Alternativa 1: Consiste en separar las aguas de refrigeracion de los efluentes industriales y cloacales, y construir una red independiente y cerrada para descargarlo al rio Mantaro. Alternativa 2: Mas viable, consiste en construir una red para recircular a la Fundicion estas aguas por medio de las bombas del Mantaro. 2. OBJETIVO: o Proteger las aguas de refrigeracion, de las fuentes de contaminacion que existen dentro del ambiente de la Fundicion. o Recuperar aproximadamente 2253 gpm, de agua de buena calidad, a traves de la recirculacion al sistema de suministro, por medio de las bombas del rio Mantaro. o Mejorar la calidad del suministro de agua proveniente de las bombas del Mantaro a la Fundicion, comparado con la calidad del agua del rio. Esto permitira dar mayor vida util a los equipos de bombeo actualmente instalados, sobre todo en epocas de venida. o Garantizar el suministro de agua a la Fundicion en epocas de estiaje. 3. DESCRIPCION DEL PROYECTO: Para la recirculacion, el agua de refrigeracion y enfriamiento se llevara desde los distintos puntos de descarga de los procesos, por medio de un sistema hidraulico POR GRAVEDAD, a traves de tuberias de distintos diametros, cuyo recorrido atravesara las zonas industriales de mayor descarga, y seran conducidos por un emisor hasta las bombas del Mantaro.

Neutralizacion a pH=7 - Precipitacion/Floculacion - Correccion de pH=10,5 - Precipitacion/Floculacion - Correccion de pH=8/9 - Vertido al rio). La separacion de los metales de los efluentes en la industria metalurgica, se viene realizando desde hace tiempo, por procesos de separacion solido/liquido. Gracias a que los hidroxidos de los metales son insolubles a pH basicos. El proceso de neutralizacion, subida de pH y precipitacion/floculacion es el mas extendido y utilizado. No solo en actividades minero-metalurgicas, sino tambien en otras actividades que tambien vierten metales, tales como, la siderurgica, altos hornos, galvanoplastia, laminacion, etc. Los lodos generados en los dos clarificadores, donde se dan procesos de floculacion/sedimentacion, seran extraidos con bombas y depositados, adecuadamente, en un vertedero (cancha de lodos) controlado, impermeabilizado con geomembrana. El agua que filtre o lixivie sera reciclada a cabecera de planta. La ayuda del floculante es necesario, porque el precipitado de los hidroxidos es gelatinoso, y una parte tiende a flotar. Por tanto, el polimero (floculante) ademas de acelerar la velocidad de sedimentacion, evita que una parte del precipitado flote y fugue por el clarificado, disminuyendo el rendimiento de separacion de este. En la tabla 3.1.1/1 se puede observar los datos principales de funcionamiento de la planta (que ha sido disenada con la ayuda de un simulador de procesos industriales aplicado al medio ambiente, Enviromental Pro Designer) y en el Diagrama No 3.1.1/1 se muestra el flujo de la planta.

No 315-96-EM/VMM. 1.- EVALUACION DEL IMPACTO En el Complejo Metalurgico La Oroya, estas escorias se descargan de los Hornos de Manga de Plomo y del Horno Reverbero, en estado liquido a 1 l00 (degree)C y 1 200(degree)C respectivamente, para luego ser granuladas por enfriamiento brusco mediante agua a presion y transportadas por gravedad en forma de "slurry", a traves de canales rectangulares hasta una bateria de tolvas, donde se realiza la separacion solido-liquido. La escoria depositada en el fondo de las tolvas, se envia por medio de un sistema de cable carril hasta el deposito de "Huanchan", distante a 2,2 Km. cruzando el rio Mantaro. Este sistema de transporte opera desde 1930, resultando en la actualidad obsoleto, con serios problemas, operativos, de mantenimiento y de capacidad de transporte. El agua que sirve para la granulacion, se descarga en forma directa al rio Mantaro, arrastrando escoria fina y/o en suspension y metales disueltos, lo cual genera un serio problema de contaminacion.

En el caso de la escoria de plomo, la descarga es continua las 24 horas del dia a un flujo de 20,3 t/h (397 t/dia). Cantidad de Agua En la actualidad se usa la cantidad de agua siguiente: Para granular escoria de cobre: 276 l/s (4 375 galones por minuto.) Para granular escoria de plomo: 224 l/s (3 547 galones por minuto.) Caracteristicas del Agua Antes de la granulacion, la temperatura del agua esta en el rango de l0 a 14(degree)C, segun la estacion climatica. Luego de esta operacion, el agua alcanza los 28 (degree)C y los analisis quimicos muestran la presencia de plomo, arsenico, cobre, fierro y solidos suspendidos, en cantidades que en algunos casos superan los limites maximos permisibles. Vapor El vapor de agua, producto de la granulacion, se descarga directamente a la atmosfera. 1.2 Sistema de Transporte Equipo El equipo de transporte "cable carril", data de 1930 habiendo sido disenado para una capacidad de produccion de solo 600 t/d. Su obsolescencia origina multiples problemas de operacion y mantenimiento, no pudiendo ser repotenciado a una capacidad de transporte mayor por su diseno, condicion y antiguedad. Capacidad El sistema existente no permite transportar las 1 100 t/d de generacion de escorias al area de deposicion en el sector denominado "Huanchan", no solo por el equipo de transporte, sino tambien, por la limitada capacidad de almacenamiento y retencion de las tolvas de recepcion de escorias que alimentan a este equipo.

Seleccion del proceso Para el sistema de desaguado se ha analizado diversos equipos como alternativas para realizar este proceso, entre los cuales podemos mencionar: Espesadores, zarandas vibratorias, tolvas de sedimentacion, equipos rotatorios INBA y el desaguador de tornillo Denver Sala. Se opto por el sistema de desaguadores rotatorios INBA ya que al ser un equipo rotatorio la posibilidad de desgate de los componentes se minimiza y la separacion (filtracion) agua/escoria es rapida. Para el sistema de transporte que reemplazara al sistema de cable carril se estudiaron las alternativas de: sistema faja cable de Cable Belt INC, sistema capsule pipe line de Mitsubishi y el sistema de fajas transportadoras hasta la margen izquierda del rio Mantaro, siendo este ultimo el que se considero la mas adecuada por menor costo en estructuras de soporte de las fajas y menores costos de mantenimiento. 2.2. Proyecto 2.2.1. Descripcion y ubicacion El proyecto considera la adquisicion e instalacion de lo siguiente: Sistema de separacion solido-liquido Se propone instalar dos (2) desaguadores rotatorios INBA de tecnologia de punta que giraran a una velocidad de 3 rpm aproximadamente, con un nuevo sistema de granulacion que utiliza una relacion de agua-escoria de 10 a 1 en peso. Con este proyecto, el agua sera continuamente recirculada, lo que evitara la contaminacion del rio Mantaro. Debe indicarse que el sistema existente para la granulacion, utiliza la relacion agua-escoria de 40 a 1 en peso. Con esta solucion, que es "tecnologia de punta", se proyecta manejar solo 183 1/s (2 900 gpm) de agua para la granulacion de las escorias de cobre y plomo. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 215. - -------------------------------------------------------------------------------- La capacidad de evacuacion de escorias de cobre y plomo del nuevo sistema sera de 1 400 t/dia, cantidad que puede cubrir facilmente futuras ampliaciones de las plantas de Cu y Pb. Nuevo Sistema de Transporte El sistema se disenara para transportar 1 400 t/d lo que cubre ampliamente la produccion actual de 1 100 t/d. La solucion consistira en la instalacion de fajas transportadoras, que permitiran el transporte de la totalidad de las escorias hasta la margen izquierda del rio Mantaro, para luego ser llevadas a su disposicion final. Este nuevo sistema de desaguadores estara ubicado en las inmediaciones del actual sistema de tolvas de almacenamiento de escorias y el sistema de transporte a partir de aqui cruzara el rio Mantaro hasta la margen izquierda. 2.2 2.

PROYECTO No. 13 ABANDONO DEL DEPOSITO DE ESCORIAS DE COBRE Y PLOMO 1.- OBJETIVO Este proyecto tiene por objetivo evaluar las condiciones de estabilidad y sobreelevacion de los depositos de escorias, y consecuentemente establecer las obras requeridas para mitigar o eliminar los impactos ambientales que afectan la tierra, el agua, la atmosfera y la vida, ademas la recuperacion y remediacion de suelos. Se considera adicionalmente las obras correspondientes para la habilitacion de un nuevo deposito que se adecue a las normas de control ambiental y futuros incrementos de produccion 2.- EVALUACION DEL IMPACTO El deposito de escorias que se encuentra en operacion desde 1930 y contiene 10 millones de toneladas de escorias de cobre y plomo, esta ubicado en la zona denominada Huanchan a 2,2 Km. del area de la Fundicion en una terraza geologica sobre la margen izquierda del rio Mantaro, adyacente a la Carretera. El transporte diario de estos residuos se hace mediante un cablecarril en un promedio de 758 TM secas. Las escorias se distribuyen formando apilamientos conicos de 70 metros en algunos casos sobre una area de 25 Ha, con niveles que varian de 3 715 hasta 3 805 msnm. Las caracteristicas de este deposito y su proximidad a la carretera central y el rio Mantaro generan como impactos ambientales tanto potenciales como reales su estabilidad y su interaccion con el medio ambiente. 2.1 ESTABILIDAD El volumen almacenado, las elevaciones de este deposito, tipo de residuo, y su cercania a un cuerpo de agua de la importancia del rio Mantaro, presentan un riesgo de estabilidad que debe ser corregido o minimizado, si se tiene en cuenta que el futuro proximo aun deber utilizado para las operaciones metalurgicas. Si bien hasta la fecha no se han tenido deslizamientos, en el caso de que este riesgo se materialice, la contaminacion por efectos de estos residuos solidos podria afectar no solo al rio en la zona de La Oroya, sino tambien a los centros poblados que se ubican aguas abajo en el valle del Mantaro. 2.2 INTERACCION CON EL MEDIO AMBIENTE La proximidad del rio Mantaro, hacen que este rio sea vulnerable en lo que a contaminacion se refiere, principalmente por el agua que fluye por el pie de sus taludes, las aguas de escorrentia por precipitacion pluvial y las infiltraciones en el terreno natural. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 221. - -------------------------------------------------------------------------------- La accion eolica tambien se manifiesta sobre el deposito arrastrando parte de las particulas finas que conforman las escorias. 3.- ALTERNATIVA PARA LA MITIGACION El proyecto de plan de cierre de estos depositos, contempla diversas medidas y obras de ingenieria a ser ejecutadas hasta el abandono total del deposito. Este trabajo que ha sido desarrollado con el apoyo de la Compania Rescan Peru S.A., tiene las siguientes caracteristicas: 3.1 ESTABILIDAD FISICA Considera las obras que deberan ejecutarse (muros de confinamiento, canales de coronacion, cunetas, etc.) para garantizar la estabilidad de los depositos contra colapsos, erosiones por escorrentia pluvial y contaminacion ambiental, dentro de limites razonables de ocurrencia sismica y lluvias extraordinarias. Para este desarrollo se han ejecutado estudios relacionados a los siguientes aspectos: o Investigaciones geotecnicas: investigaciones de campo, ensayos de laboratorio, clasificacion de suelos, descripcion del perfil estatigrafico, determinacion de parametros de resistencia a partir de ensayos SPT, etc. o Evaluacion de estabilidad de los depositos existentes: estabilidad de taludes de escorias, estabilidad de la ladera adyacente al deposito, metodos de analisis. o Potencial de crecimiento y capacidad remanente. o Estabilidad contra escorrentias pluviales. o Control contra infiltraciones. o Estabilidad contra erosion eolica. o Control de efluentes. Los muros de confinamiento que se proyecta en el perimetro de los depositos, asi como las cunetas que serviran para evacuar las aguas de las infiltraciones deberan ser construidas empleando concreto resistente a las heladas y al ataque de sulfatos. Para la estabilidad contra escorrentias pluviales se construiran canales de coronacion (inclinacion constante de 5(degrees)) en las laderas adyacentes a los depositos para captar un caudal de aproximadamente 45 l/seg. Las infiltraciones hidricas de un valor de 8,1 l/seg., seran captadas por una cuneta proyectada al pie del talud del deposito de escorias y conducidas hasta el rio Mantaro. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 222. - -------------------------------------------------------------------------------- 3.2 MEDIDAS DE CONTROL AMBIENTAL POST-CIERRE Corresponde a todas las medidas que deben tomarse para efectuar los controles, tanto de estabilidad como de efluentes, una vez abandonado el deposito, de manera de comprobar anomalias que deberan ser corregidas oportunamente, garantizando la conservacion del medio ambiente. Todas las acuavias deberan tener como minimo mantenimiento anual antes y despues de la epoca de lluvia (octubre a abril), se efectuaran analisis quimicos periodicos de todos los efluentes, escorrentias y afloramientos provenientes del deposito, para ejecutar las medidas correctivas pertinentes, en caso de ser necesarias. 3.3 CAPACIDAD DE ALMACENAMIENTO Y NUEVO DEPOSITO El nivel de sobreelevacion maximo recomendado del sistema actual de almacenamiento es 3 762 msnm, siendo la capacidad remanente del deposito de 2,36 millones de m^3 para una vida util de almacenamiento de escorias de 10 a 13 anos. El nuevo deposito estara ubicado en Cochabamba, a 9 Km. de La Oroya camino a Huancayo y en la margen izquierda del rio Mantaro, este deposito sera construido con todas las exigencias de seguridad y de control de medio ambiente. 4.- RESULTADOS DE LA MITIGACION La implementacion de este proyecto permitira cubrir los siguientes aspectos: 4.1 CONTAMINACION Minimizara la contaminacion del rio Mantaro. Los analisis quimicos de las aguas provenientes de drenaje y/o escorrentias, indican que contienen porcentajes permisibles que no afectan las aguas naturales del entorno, por lo que se considera que las aguas captadas por las cunetas, seran descargadas directamente al rio Mantaro previa sedimentacion, por lo que no sera necesario la construccion de sistemas de tratamiento de aguas. 4.2 ESTABILIDAD Y RECUPERACION DEL AREA Garantizara una estabilidad estatica y dinamica de las pilas de almacenamiento de escorias ante el caso de una sobrecarga o un movimiento sismico, condicion de suma importancia por estar La Oroya localizada en una region calificada de alta sismicidad. La recuperacion y remediacion del deposito, se efectuara con el plan de abandono, proyectandose al final de la vida util del mismo, el de disponer de un area de condiciones seguras y similares a la que existiera al comienzo de las operaciones metalurgicas. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 223. - -------------------------------------------------------------------------------- 4.3 OPERATIVIDAD Se asegurara la continuidad operativa de las Fundiciones de Cobre y Plomo, durante el tiempo de vida remanente del deposito actual y luego con el uso de un nuevo deposito. Permitiendo de esta manera, iniciar el proceso de cierre del deposito de Huanchan y en el futuro disponer de un deposito adecuado para las escorias generadas. 5.- PRESUPUESTO DE INVERSIONES Las inversiones para la implementacion del proyecto, tendran el siguiente detalle: -------------------------------------------------------------------- DESCRIPCION MONTO (US$) SUB-TOTAL (US$) -------------------------------------------------------------------- 1.0 Nuevo deposito de Cochabamba 2 200 000 2 200 000 -------------------------------------------------------------------- 2.0 Deposito existente -------------------------------------------------------------------- 2.1 Obras proteccion y estabilidad 2 000 000 -------------------------------------------------------------------- 2.2 Obras complementarias 550 000 -------------------------------------------------------------------- 2.3 Tratamientos y restauracion 2 000 000 4 550 000 -------------------------------------------------------------------- SUB-TOTAL 6 750 000 -------------------------------------------------------------------- IMPREVISTOS +/- 15% 1 000 000 -------------------------------------------------------------------- TOTAL 7 750 000 -------------------------------------------------------------------- 6.- CRONOGRAMA DE EJECUCION El Cronograma de ejecucion del proyecto se estima requerira de cuatro (4) anos bajo el siguiente detalle: -------------------------------------------------------------------- ANO ACTIVIDAD MONTO (US$) -------------------------------------------------------------------- 1997 Deposito existente, obras para estabilidad 1 250 000 -------------------------------------------------------------------- 1998 Nuevo deposito de Cochabamba 2 500 000 -------------------------------------------------------------------- 1999 Deposito existente, proteccion, tratamiento y otros 2 500 000 -------------------------------------------------------------------- 2000 Deposito existente, recuperacion y remediacion 1 500 000 -------------------------------------------------------------------- TOTAL 7 750 000 -------------------------------------------------------------------- PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 224. - -------------------------------------------------------------------------------- 5.4.14 PROYECTO No 14 PROYECTO: DEPOSITO DE TRIOXIDO DE ARSENICO, ABANDONO DEL DEPOSITO DE MALPASO, CIERRE DEL DEPOSITO DE VADO Y NUEVO DEPOSITO EN VADO 1. OBJETIVO Este proyecto tiene por objetivo principal mitigar en forma integral la contaminacion ambiental ocasionada por los depositos de trioxido de arsenico generado en el Complejo Metalurgico de La Oroya, acorde a los niveles maximos permisibles para efluentes liquidos fijados en la Resolucion Ministerial No 011-96-EM/VMM del 10 de enero de 1 996 y niveles maximos permisibles de elementos y compuestos presentes en emisiones gaseosas provenientes de las unidades minero-metalurgicos fijados en la Resolucion Ministerial No 315-96-EM/VMM del 16 de julio de 1 996 del Ministerio de Energia y Minas. 2. EVALUACION DEL IMPACTO El trioxido de arsenico es un residuo de la fundicion, producto del procesamiento de concentrados de cobre y plomo. Por sus escasas ventas, este material ha sido depositado en dos areas, una desde 1 992 en Malpaso, operativo durante aproximadamente 25 anos, y otra en la zona de Vado, en actual uso. Ambos depositos, si bien fueron construidos bajo los estandares de aquella epoca, no ayudan a preservar las exigencias actuales de control de calidad del agua que agua que percola en epocas de lluvia y del aire atmosferico. 2.1 Caracteristicas de los Depositos Deposito de Malpaso Ubicacion: Se encuentra en la llanura aluvial del rio Mantaro, aproximadamente un kilometro aguas abajo de la planta hidroelectrica de Malpaso y cerca de 19 kilometros rio arriba de la fundicion de La Oroya (Figura 1). Volumen: Como resultado preliminar de la investigacion del sitio realizada por ADI International Inc. de Canada, el volumen de material de desecho se ha estimado en 38 000 m^3, equivalente a una 45 000 t de residuo. Topografia: La mayoria del deposito esta cubierto con piedra de la localidad y no es inmediatamente evidente a simple vista, aunque hay muchas calicatas donde el trioxido de arsenico esta expuesto. La topografia del lugar se muestra en la Figura 2-Area de Malpaso. Condiciones Operativas: Este es un deposito utilizado desde el ano 1 992 por aproximadamente 25 anos y se encuentra en desuso. Deposito de Vado Ubicacion: Se encuentra en la llanura aluvial del rio Mantaro, cerca de 9 kilometros rio arriba de la fundicion en direccion a Cerro de Pasco. El acceso es por via asfaltada en buenas condiciones. Tambien se llega por ferrocarril (Figura 1). PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 225. - -------------------------------------------------------------------------------- Volumen: Basados en los resultados preliminares de la investigacion del sitio reportados por ADI International Inc. de Canada, el volumen de trioxido de arsenico depositados se ha estimado en 97 000 m^3, equivalentes a unas 115 000 t. Topografia: La mayor parte del area del deposito se encuentra expuesto al medio ambiente. La topografia del lugar se muestra en la Figura 2-area de Vado. Condiciones Operativas: Actualmente en uso.

L.M.P.(1): Limites Maximos Permisibles en Cualquier Momento (mg/l). L.M.P.(2): Limites Maximos Permisibles Valor Promedio Anual (mg/l). Del cuadro se deduce que se incrementa la concentracion de arsenico en el rio Mantaro despues del stock Vado, lo que explica la existencia de contaminacion de dicho rio con arsenico. En cuanto a los otros elementos como cobre, plomo y fierro se observa infimos incrementos que no merecen nuestra atencion. Referente al pH practicamente no se observa variacion al haberse registrado valores entre 7,3 y 7,8 para ambas muestras de agua. 2.3 Calidad de Aire Adicionalmente se tiene una contaminacion por accion eolica principalmente sobre el material depositado en Vado. El aire atmosferico aledano es monitoreado en forma continua en una estacion ubicada en Casaracra (a 1 km al norte del deposito de Vado). En esta estacion, en el periodo enero-diciembre de 1995 el contenido de arsenico promedio fue de 0,220 (microgram)/m^3, mientras que en el periodo correspondiente a enero-junio de 1996 fue de solo 0,086 (microgram)/m^3. Esta disminucion se explica porque parte de la superficie se ha cubierto con tierra de la zona y en el extremo Oeste del area se han realizado pruebas de deposito en dos modulos de 500 m^2 cada uno, utilizando geomembrana en uno y en el otro arcilla y ademas cubriendo la superficie con tierra de cultivo y pastos. 3. ALTERNATIVAS DE MITIGACION Al respecto la firma canadiense ADI INTERNATIONAL INC. contratada por Centromin Peru S.A., ha estudiado diferentes alternativas de abandono y cierre de estos depositos asi como la construccion de uno nuevo para la futura produccion de trioxido de arsenico. Estos estudios, cuyo alcance llega al nivel de ingenieria basica y ademas prapara los terminos de referencia para la elaboracion de la ingenieria de detalle, se encuentran sujetas a los requerimientos y concuerda con la guia publicada por el Consejo Canadiense de Ministros del Medio Ambiente descrita en el "National Guidelines for The Landfilling of Hazardous Waste", CCME-WM/TR-028E, y tambien con la publicacion de La Agencia de Proteccion del Medio Ambiente de Estados Unidos "Lining of Waste Contaiminent and Other Impoundment Facilities", EPA/600/2-88/052. Los trabajos tambien incluyen la ejecucion de los estudios de las condiciones hidrogeologicas y geotecnicas de las areas involucradas previas al diseno, el diseno y especificaciones del sistema de monitoreo de la post-construccion, y la praparacion de las especificaciones de construccion para el deposito. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 227. - -------------------------------------------------------------------------------- Luego de analizar las diversas alternativas de cierre y abandono: sellado del deposito en el lugar, transferir el material a un deposito disenado para el proposito fuera del deposito, posiblemente en el aeropuerto, transferencia del material a un deposito seguro en el sitio y solidificacion de los desechos usando concreto, polimeros u otros metodos, se opto por el desarrollo de un sistema de deposito seguro en el sitio, como se describe en cada caso. 3.1 Abandono del Deposito de Malpaso El deposito requerido consiste de un sistema compuesto de forrado de fondo, una cubierta compuesta y un sistema de deteccion y monitoreo de lixiviado, ambos disenados para controlar la liberacion de contaminantes en el medio ambiente y control del potencial de exposicion del publico a estos. El sistema esta disenado para permitir que aproximadamente el 50% de los desechos sean excavados del area y movidos a un deposito provisional. La primera de las dos celdas propuestas seran construidas en el area excavada, los desechos del area removida seran excavados y movidos a la nueva celda, una segunda celda entonces sera construida en el area excavada y el desecho del deposito provisional sera depositado en esta segunda celda. El concepto es mostrado en el Plano Numero 1-Malpaso Site. Se estableceran las implicancias del escurrimiento de aguas superficiales, los que seran impedidos en el diseno del deposito, incluyendo el manejo de los eventos pico durante la construccion. El deposito requerido consistira en un sistema compuesto de doble Forro de Membrana Flexible (Flexible Membrane Liner) en el fondo, una simple cobertura compuesta FML en la parte superior y un sistema de deteccion de lixiviado entre las FML del fondo. El concepto y todos los detalles se muestran en el Plano Numero 1-Malpaso Site, junto con las secciones de la cobertura superior y la del fondo del sistema. Este concepto es consistente con las especificaciones de el CCME y el EPA, con la excepcion que los requerimientos para el sistema de coleccion de lixiviado han sido eliminados. El sistema de coleccion de lixiviado no es requerido ya que la celda sera inmediatamente sellada despues de colocar los desechos y no habra produccion de solucion dentro de la celda. 3.2 Cierre del Deposito de Vado El trabajo de encapsulamiento sera similar al de Malpaso, pudiendo tener como area temporal una zona del nuevo deposito. Este trabajo puede ejecutarse tambien en forma modular. El sistema debera ser disenado para permitir que aproximadamente un tercio de los desechos sean excavados del area y acumulados sobre el area restante del deposito. Este procedimiento requerira la construccion de una berma de confeccion alrededor del area para evitar que los desechos acumulados se escurran hacia fuera del deposito, la zona de donde se extrajo el material sera preparada y se construira una celda de deposito seguro en ella. A continuacion se colocara en esta celda aproximadamente un tercio de los desechos y se sellara. Este procedimiento sera repetido dos veces para acomodar los dos PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 228. - -------------------------------------------------------------------------------- tercios de desechos restantes, resultando al final en un deposito seguro consistente de tres celdas individuales. Este concepto y los detalles se muestran en el Plano No 1-Vado Existing Site, e incluye una ilustracion de las etapas del manipuleo de los desechos y de la construccion de las celdas. El area de deposito temporal sera disenada para controlar la migracion de los desechos contaminados o su lixiviacion durante el periodo en el cual el deposito temporal este en uso. El deposito temporal sera cerrado cuando se complete la construccion de las celdas. Como el concepto utilizado para el abandono de Malpaso, este concepto es consistente con las especificaciones de el CCME y el EPA, con la excepcion que los requerimientos para el sistema de coleccion de lixiviado han sido eliminados, ya que la celda sera inmediatamente sellada despues de colocar los desechos y no habra produccion de solucion dentro de la ceida. 3.3 Nuevo Deposito (Vado II) En la zona del antiguo aeropuerto, bajo la misma tecnica de encapsulamiento, pero en forma modular, se acondicionara el area y se iniciaran los trabajos para la fabricacion de celdas. Debido a la produccion de solo 4 000 t por ano de trioxido de arsenico, el area proyectada para la colocacion de la nueva produccion, sera para un volumen final 50 000 m^3 y un tiempo de vida util de 25 anos. Debera ser disenada con una configuracion de celdas multiples. El uso de una configuracion de celdas multiples proporciona un grado adicional de flexibilidad en el almacenaje del desecho de arsenico, asimismo asegura que el periodo de exposicion del desecho a los elementos puede ser controlado y limitado a un maximo de celda abierta de 5 anos. Las especificaciones y detalles del sistema propuesto se muestran en el Plano No 1-Vado Aeroport Site. Teniendo en cuenta que cada celda individual del nuevo deposito estara abierta por un periodo de 5 anos, es posible que se genere un lixiviado durante los periodos de lluvia. Por lo tanto el diseno del deposito debera incluir el sistema de tratamiento de lixiviado. El sistema de tratamiento debera ser disenado para manejar la generacion de lixiviado de todas las tres celdas y debera incluir elementos de muestreo para la caracterizacion del lixiviado y un sistema para la descarga del agua tratada y residuos, sean estos de arsenato de fierro o calcio que se mezclaran con el trioxido de arsenico en las celdas. 3.4 Presupuesto de Inversiones La inversion para la implementacion de los proyectos mencionados, tienen el siguiente detalle: PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 229. - -------------------------------------------------------------------------------- -------------------------------------------------------------------- DESCRIPCION MONTO US$ -------------------------------------------------------------------- 1.0 Abandono del deposito de Malpaso 2 800 000 -------------------------------------------------------------------- 2.0 Cierre del deposito de Vado 4 800 000 -------------------------------------------------------------------- 3 0 Nuevo deposito 1 750 000 -------------------------------------------------------------------- SUB-TOTAL 9 350 000 -------------------------------------------------------------------- Imprevistos 1 350 000 -------------------------------------------------------------------- TOTAL 10 700 000 -------------------------------------------------------------------- 3.5 Cronograma de ejecucion El cronograma de ejecucion del proyecto se estima requerira de cinco (5) anos bajo el siguiente detalle: -------------------------------------------------------------------- ANOS ACTIVIDAD MONTO SUB-TOTAL US$ US$ -------------------------------------------------------------------- 1 997 Deposito de Malpaso 1 625 000 1 625 000 -------------------------------------------------------------------- 1 998 Deposito de Malpaso (fin) y 2 000 000 2 000 000 Deposito de Vado (inicio) -------------------------------------------------------------------- 1 999 Nuevo deposito 1 000 000 Deposito de Vado (cont.) 2 000 000 3 000 000 -------------------------------------------------------------------- 2 000 Nuevo deposito (cont.) 1 000 000 Deposito de Vado (fin) 1 600 000 2 600 000 -------------------------------------------------------------------- 2 001 Obras Complementarias 1 475 000 1 475 000 -------------------------------------------------------------------- TOTAL 10 700 000 -------------------------------------------------------------------- 4. RESULTADOS DE MITIGACION La solucion propuesta permitira solucionar en forma integral el problema de contaminacion, abandonando los depositos existentes y construyendo un nuevo deposito con tecnologia de avanzada y que se ajuste a las normas y requerimientos mas exigentes a nivel mundial. El area de los antiguos depositos quedara al final de los trabajos de una apariencia natural, similar al de su entorno. Los controles y muestreos tanto de la calidad de aire del medio ambiente como del agua que discurre por el rio Mantaro, estaran acorde a los niveles maximos permisibles establecidos en la resoluciones del Ministerio de Energia y Minas No 011-96-EM/VMM del 10 de enero de l996 y No 315-96-EM/VMM del 16 de julio de 1996.

OBJETIVO Este proyecto tiene por objetivo evaluar las condiciones de estabilidad y sobreelevacion de los depositos de ferritas de zinc, y consecuentemente establecer las obras requeridas para mitigar o eliminar los impactos ambientales que afectan la tierra, el agua, la atmosfera y la vida, ademas la recuperacion y remediacion de suelos. El proyecto contempla como medidas de mitigacion para las ferritas de zinc dos escenarios: o Ampliacion de los depositos No 3 y 4 y abandono tecnico de los cuatro depositos. o Factibilidad tecnico-economica para el procesamiento. 2. EVALUACION DEL IMPACTO La obtencion del zinc refinado desde los concentrados sulfurados de zinc en el complejo metalurgico de La Oroya se lleva a cabo a traves de procesos pirometalurgicos e hidrometalurgicos (tostacion, lixiviacion, purificacion, electrodeposicion, fusion y moldeo). En el proceso hidrometalurgico de lixiviacion se realiza la disolucion del zinc de las calcinas (producto de la tostacion de concentrados) en un lixiviante acido (electrolito gastado) obteniendose una solucion de sulfato de zinc y un residuo solido cuyo compuesto principal (75,0%) es conocido como "Ferritas de Zinc" (Fe(2)O(3)ZnO). Los volumenes de residuos generados (115,0 t/d) en la etapa de lixiviacion sobrepasa la capacidad de tratamiento de la planta "Zileret" (50 t/d), situacion que obliga a almacenar el excedente en los depositos ubicados en Huanchan a 3 km. del complejo metalurgico. Al 31 de octubre de 1996 se tiene almacenados 1 242 797 t. Las pulpas de ferritas se depositan en pozas conformadas por diques perimetricos de material prestado. Para satisfacer la creciente demanda de capacidad, las alturas de los diques son constantemente incrementadas siguiendo la metodologia "aguas arriba" sin compactacion ni adicion de humedad. El agua que trae la pulpa de ferritas es decantada en uno de los extremos de cada poza y evacuado por una tuberia enterrada hacia el rio Mantaro por su ladera izquierda. Las condiciones climaticas tales como vientos y lluvias originan por un lado arrastre de las particulas finas al medio ambiente y disolucion de las sales solubles (SO(4)Zn) que finalmente descargan al rio Mantaro.

PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 238. - -------------------------------------------------------------------------------- 2.2 CALIDAD DE AIRE La contaminacion del medio ambiente por accion eolica tiene lugar debido a que el material humedo depositado en las pozas al secarse por accion de la temperatura solar se convierte en polvo fino que es arrastrado por el viento. El aire atmosferico aledano es monitoreado en forma continua en una estacion ubicada entre los depositos de escoria y de Ferritas en Huanchan. En esa estacion, en el periodo Enero-Agosto de 1996 se analizaron los elementos mostrados a continuacion cuyos contenidos estan dentro de los niveles maximos permisibles a excepcion del plomo el cual reporta un contenido promedio de 2.7 (micro)g/m^3, superior a los niveles maximos permisibles y que probablemente esta influenciado por las emisiones gaseosas de la chimenea principal del complejo cuya descarga por accion del viento es orientada hacia ese lugar. - -------------------------------------------------------------------------------- ANALISIS DE MATERIAL PARTICULADO EN HUANCHAN ENERO - AGOSTO DE 1996 - -------------------------------------------------------------------------------- MES (micro)g/m^3 - -------------------------------------------------------------------------------- SPM As Pb Cd - -------------------------------------------------------------------------------- ENE 71.517 0.036 0.215 0.007 - -------------------------------------------------------------------------------- FEB 120.143 0.493 1.105 0.024 - -------------------------------------------------------------------------------- MAR 60.422 0.453 0.906 0.024 - -------------------------------------------------------------------------------- ABR 79.713 0.797 1.036 0.032 - -------------------------------------------------------------------------------- MAY 175.617 2.107 4.390 0.263 - -------------------------------------------------------------------------------- JUN 297.440 6.544 10.113 0.476 - -------------------------------------------------------------------------------- JUL 237.019 0.640 0.427 0.095 - -------------------------------------------------------------------------------- AGO 121.979 1.134 3.537 0.110 - -------------------------------------------------------------------------------- PROM 145.481 1.526 2.716 0.129 - -------------------------------------------------------------------------------- NIVELES MAXIMOS PERMISIBLES - -------------------------------------------------------------------------------- SPM* As* Pb** - -------------------------------------------------------------------------------- 350 6.0 1.5 - -------------------------------------------------------------------------------- (*) Concentracion media aritmetica diaria (**) Concentracion mensual - -------------------------------------------------------------------------------- 2.3 CALIDAD DE AGUA Por estar los depositos de los residuos lixiviados ubicados en la ribera del rio Mantaro, en un area de material aluvial y ademas expuestos a la accion de las lluvias las que se intensifican en las epocas de invierno, percolan y ocasionan la disolucion de las sales solubles de Zn y otros elementos, las cuales llegan a discurrir y contaminar el rio Mantaro.

ALTERNATIVAS DE MITIGACION El proyecto de las ferritas de zinc contempla diversas medidas y obras de ingenieria a ser ejecutadas, hasta el cierre total de los depositos; en ese sentido la mitigacion de los impactos ambientales, por ellos, esta enmarcado dentro de dos escenarios 3.1 PRIMER ESCENARIO: Abandono tecnico de los depositos 3.1.1 ESTABILIDAD FISICA Considera las obras que deberan ejecutarse (muros de confinamiento, canales ce coronacion, cunetas, etc.) para garantizar la estabilidad de los depositos contra colapsos, erosiones por escorrentia pluvial y contra contaminacion ambiental, dentro de limites razonables de ocurrencia sismica y lluvias extraordinarias. Para este desarrollo se han ejecutado estudios relacionados a los siguientes aspectos: o Investigaciones geotecnicas: investigaciones de campo, ensayos de laboratorio, clasificacion de suelos, descripcion del perfil estatigrafico, determinacion de parametros de resistencia a partir de ensayos SPT, etc. o Evaluacion de estabilidad de los depositos existentes: estabilidad de taludes de escorias, estabilidad de la ladera adyacente al deposito, metodos de analisis. o Potencial de crecimiento y capacidad remanente. o Estabilidad contra escorrentias pluviales. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 241. - -------------------------------------------------------------------------------- o Control contra infiltraciones. o Estabilidad contra erosion eolica. o Control de efluentes. Los muros de confinamiento que se provecta en el perimetro de los depositos, asi como las cunetas que serviran para evacuar las aguas de las infiltraciones deberan ser construidas empleando concreto resistente a las heladas y al ataque de sulfatos. Para la estabilidad contra escorrentias pluviales se construiran canales de coronacion (inclinacion constante de 50(degrees) en las laderas adyacentes a los depositos para captar un caudal de aproximadamente 45 l/seg. Las infiltraciones hidricas seran captadas por una cuneta proyectada al pie de los taludes de los depositos y conducidos al rio Mantaro. 3.1.2 CAPACIDAD DE ALMACENAMIENTO La capacidad de almacenamiento de los depositos No 1 y 2 esta en el limite, los cuales deben tener un reforzamiento de los taludes y abandonarse tecnicamente. Los depositos No 3 y 4 si tienen un potencial de crecimiento (sobreelevacion) y pueden continuar almacenando residuos por un periodo de tiempo relativamente corto; sin embargo deben efectuarse reforzamiento de todos los taludes cuya estabilidad fisica lo requiera. 3.1.3 MEDIDAS DE CONTROL AMBIENTAL Corresponde a todas las medidas que deben tomarse para efectuar los controles, tanto de estabilidad como de efluentes; Con respecto a la estabilidad fisica el reforzamiento de todos los taludes de las cuatro pozas garantizaran la estabilidad ante cualquier contingencia sismica, y en cuanto a los efluentes liquidos que emanan los depositos, estos seran solucionados con la implementacion de una planta de tratamiento de efluente liquidos industriales para fundicion y refinerias; en tal sentido la solucion descargada al rio Mantaro estara dentro de los limites permisibles establescidos por M.E.M. 3.2 SEGUNDO ESCENARIO: Factibilidad tecnico - economica de procesamiento de las ferritas de zinc Las ferritas de zinc almacenadas en el lugar conocido como Huanchan distante a 3 km. del complejo metalurgico de La Oroya (diagrama No 4.1.3/1 - Capitulo IV) alcanzan a 1 242 739 t valorizados aproximadamente en US $ 230 millones en sus contenidos metalicos de Zn, Ag. Cd, Cu.

Pta: 60 000 t/ano - -------------------------------------------------------------------------------- Tecnologia de Lixiviacion presurizada con concentrados de zinc Esta tecnologia como alternativa consiste en reemplazar los tres tostadores de cama fluida (FBR) y el tostador de lecho turbulento (TLR) por una planta de lixiviacion a presion en autoclaves, para tratar directamente los cancentrados de zinc (sphalerite) a traves de la tecnologia de lixiviacion a presion (SHERRIT). Esta planta de lixiviacion, para una produccion de 70 000 t.p.a. de zinc refinado tiene un costo de US $ 40 millones, comparado con el costo de un nuevo TLR y su respectiva planta de acido sulfurico que es del orden de los US $ 52,9 millones. La tecnologia de lixiviacion a presion permitira en la planta Zileret (Horno Kiln de 50 t de capacidad/ dia) pueda emplearse para procesar exclusivamente las ferritas almacenadas en Huanchan, asi mismo tendra otras ventajas tales como: o Se solucianaria el problema de emisiones de gases SO(2) debido a que el azufre se fijaria coma azufre elemental, aun cuando es conocido que su mercado es limitado. o Permitira contrarrestar el problema de parque automotor para el transporte de acida sulfurico, asi como tambien la capacidad de almacenaje. 4. RESULTADOS DE LA MITIGACION La implementacion de este proyecto permitira cubrir los siguientes aspectos: 4.1 CONTAMINACION Minimizara la contaminacion del rio Mantaro. Los analisis quimicos de las saluciones descargadas por la planta de tratamiento de efluentes se adecuara a los limites permisibles establecidos par el M.E.M. y las aguas provenientes de drenaje y/o escorrentias, indican que contienen porcentajes permisibles que no afectan las aguas naturales del entorno, por lo que se considera que las aguas captadas par las cunetas construidas seran descargadas directamente al rio Mantara, previa sedimentacion por lo que no sera necesario la construccion de sistemas de tratamiento de aguas. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 243. - -------------------------------------------------------------------------------- 4.2 ESTABILIDAD FISICA Garantizara una estabilidad estatica y dinamica de los depositos de almacenamiento de ferritas ante un movimiento sismico, condicion de suma importancia por estar La Oroya localizada en una region calificada de alta sismicidad 4.3 RECUPERACION DE VALORES MITALICOS DE LAS FERRITAS Las tecnologias arriba mencionadas permiten recuperar los valores metalicos contenido en las ferritas de zinc, para que en el futuro sea posible recuperar los suelos con un cierre definitivo de los depositos. 5.

PROYECTO No. 16 TRATAMIENTO DE AGUAS SERVIIDAS Y DISPOSICION DE BASURA EN LA OROYA 1.- OBJETIVO La ejecucion de las obras de ingenieria pertinentes y la adquisicion e instalacion de equipos, que permitan efectuar el tratamiento de aguas servidas y disposicion de basura de las zonas de vivienda dependientes de Centromin Peru S.A., para evitar la contaminacion por estos conceptos del rio Mantaro, cumpliendo con los requerimientos senalados por las entidades gubernamentales. 2.- EVALUACION DEL IMPACTO El sistema de alcantarillado que se dispone en las areas de vivienda de Centromin Peru a lo largo de las riberas del rio Mantaro constituye una red que permite colectar la casi totalidad de las aguas servidas y de escorrentia, se encuentra en buen estado de conservacion, pero sus descargas van en forma directa al mencionado rio. Estos vertimientos sin ningun tratamiento, se constituyen en uno de Los contaminantes del rio Mantaro. En relacion a la basura, su recojo se realiza con un camion compactador, el cual no abastece la demanda existente, al tener que recorrer adicionalmente nueve kilometros desde el punto de recoleccion. En el area de disposicion, la basura es colocada sin seguir las tecnicas de un relleno sanitario, situacion que se complica por estar este deposito en la margen izquierda del rio Mantaro, muy proxima al cauce de sus aguas. Constituyendose por lo tanto en un punto adicional de contaminacion. 3.- ALTERNATTVA PARA LA MITIGACION Contandose con el apoyo de la firma AQUAPLAN INGENIEROS SRL, luego de analizadas diversas alternativas de solucion desde el punto de vista tecnicoeconomico, se definio para el caso de las aguas servidas, la alternativa de tratamiento con dos (2) plantas de lodos activados por el metodo de aereacion extendida. Para la disposicion de basuras, se adopto la solucion de relleno sanitario bajo el metodo de trinchera, el cual esta dentro de las normas emitidas por el Ministerio de Salud (DIGESA). 3.1 TRATAMIENTO DE AGIJAS SERVIDAS Para tal efecto se ha considerado dos (2) plantas para las areas de vivienda ubicadas a lo largo de las riberas del rio Mantaro, una en la zona de Chulec y la otra frente al hotel Inca en la zona de Sudete. El proyecto considera tambien las lineas de interseccion, conduccion y coleccion de las aguas servidas hacia las plantas de tratamiento. Debido a las caracteristicas topograficas de La zona sera necesario instalar estaciones de bombeo.

De esta manera se PAMA COMPLEJO METALURGICO - LA OROYA Capitulo V Pag 247. - -------------------------------------------------------------------------------- iniciara la materializacion del desarrollo sustentable que sefialan los conceptos fundamentales del control del medio ambiente. Este proyecto si bien se encuentra a nivel de ingenieria de detalle, ha merecido la atencion de organismos como el Ministerio de la Presidencia, pues la solucion adoptada esta siendo considerada dentro de los planes del saneamiento integral de la ciudad de La Oroya. 5.- PRESUPUESTO DE INVERSIONES El proyecto de tratamiento de aguas servidas y disposicion de basura, requerira la ejecucion de las siguientes items y montos de ejecucion que incluyen, en cuanto a equipos, solo se considera la adquisicion de dos (2) camiones compactadores recolectores: DESCRIPCION MONTO (US$) SUB-TOTAL (US$) ----------- ----------- --------------- 1.1 Obras de intercepcion y 425 000 425 000 conduccion. 1.2 Plantas de tratamiento Chulec 1 100 000 Sudete 1 100 000 1.3 Disposicion de Basura 425 000 2 625 000 SUB-TOTAL 3 050 000 IMPREVISTOS +/-15% 450 000 TOTAL 3 500 000 6.- CRONOGRAMA DE EJECUCION El Cronograma de ejecucion del proyecto se estima requerira de tres (3) anos bajo el siguiente detalle: ANO ACTVIDAD MONTO (US$) SUB-TOTAL CUSS) --- -------- ----------- --------------- 1998 Obras de intercepcion y 500 000 conduccion Mayupampa, Chulec, Amachay, Hidro Disposicion de Basura 500 000 1 000 000 1999 Planta de tratamiento en 1 250 000 1 250 000 Chulec 2000 Planta de tratamiento en 1 250 000 1 250 000 Sudete TOTAL 3 500 000 -------------------------- CAPITULO VI -------------------------- PAMA COMPLEJO METALURGICO - LA OROYA Capitulo VI Pag 248. - -------------------------------------------------------------------------------- 6. PLAN DE CIERRE 6.1. Escenario Debido a la importancia que el complejo metalurgico tiene dentro del desarrollo socioeconomico de la region, por ser el centro industrial de mayor generador de empleo y divisas, al producir metales que en gran volumen se exportan a diferentes paises del mundo, la probabilidad de un cierre de sus operaciones no es predecible en el corto y mediano plazo. Si se considera adicionalmente su magnitud, diversidad y complejidad de sus operaciones metalurgicas, al ser una de las cuatro fundiciones del mundo capaces de tratar concentrados polimetalicos con un porcentaje alto de impurezas, el plan de cierre respectivo, debera considerar innumerables acciones de planeamiento y ejecucion que estaran sujetas durante su implementacion, no solo a cuestiones netamente tecnicas sino tambien a decisiones economicas o politicas. 6.2. Alcance Segun se estipula en los dispositivos legales relacionados al medio ambiente, es necesario desarrollar un Plan de Cierre de toda unidad industrial en operacion, con el proposito de disponer al cese de sus operaciones, de un programa de actividades que permitan garantizar la restauracion y recuperacion del area del emplazamiento, hasta niveles aceptables para usos futuros. Bajo este esquema el Complejo Metalurgico de La Oroya, ha desarrollado un plan de cierre hasta el nivel de ingenieria basica con el apoyo de la firma canadiense ADI INTERNATIONAL INC. Por las consideraciones indicadas, se estima que el Plan de Cierre se llevara acabo en el largo plazo, razon por la cual en el desarrollo del presente PAMA, tal como puede apreciarse en los capitulos precedentes, se ha proyectado diversos trabajos de mitigacion y de modernizacion de procesos, que estan orientados a solucionar los problemas ambientales existentes, hasta alcanzar o mejorar los niveles permisibles exigidos. El alcanzar estos niveles, circunscribe el Plan de Cierre, al estudio de los emplazamientos de sus areas industriales tanto de la Fundicion como el de las Refinerias de Cobre y Plomo, en una extension total de 55 hectareas. 6.3. Situacion Actual La antiguedad del Complejo Metalurgico La Oroya, la gran cantidad de edificaciones, equipos de proceso tanto mecinicos, electricos y de control, y la diversidad de procesos metalurgicos para la fundicion y refinacion de los 20 metales entre productos y subproductos, ha dado como origen que parte de la extension de su emplazamiento haya sido afectadas por la contaminacion originada por la actividad industrial. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo VI Pag 249. - -------------------------------------------------------------------------------- Se tiene por lo tanto un escenario propio de una zona industrial de alta congestion, que tendria que ser revertido a una condicion similar a la que tuvo antes del inicio de su actividad industrial. 6.4. Objetivo Desarrollo de los estudios de ingenieria hasta el nivel basico, que permitan ejecutar el plan de cierre del Complejo Metalurgico de acuerdo con los alcances senalados para el PAMA. Dentro de estos lineamientos se considera la remocion de las instalaciones existentes, eliminacion de fuentes de contaminacion, recuperacion de suelos y las respectivas obras de remediacion, hasta devolver al area sus caracteristicas iniciales antes de las operaciones metalurgicas. 6.5 Plan de cierre El cierre de los procesos operacionales en los complejos de la Fundicion y Refinerias resultara en un decrecimiento dramatico del volumen y cantidad de los contaminantes emitidos, pero su ejecucion requerira de un planeamiento detallado de actividades que se inician con la decision de cierre y terminan con la implementacion de medidas de recuperacion del area y los controles de post-cierre. Este Plan de Cierre, si bien no parece ser de ejecucion inmediata, constituira el elemento de planeamiento mas importante, no solo al final de las operaciones, sino ante la eventualidad de cierres parciales. Por otra parte, el planeamiento detallado de las varias fases del cierre como los trabajos de demolicion y desmantelamiento, restauracion a niveles aceptables de calidad ambiental y otros inherentes al caso, permitiran un uso racional de recursos, al tener que requerirse cantidades considerables de tiempo y dinero. 6.5.1 Fases de Cierre Para implementar el cierre debera ejecutarse un plan maestro que considere todos los aspectos del cierre, desde el agotamiento de las existencias en proceso hasta las investigaciones en el area despues de la demolicion de las instalaciones. Para la confeccion e implementacion de este plan maestro detallado se ha considerado llevar a cabo las siguientes cuatro fases principales: o Planeamiento de detalle o Establecimiento de controles de medio ambiente o Desmantelamiento y demolicion o Investigacion y recuperacion del area. El planeamiento de detalle, proveera toda la documentacion pertinente al plan maestro para el desmantelamiento, demolicion y recuperacion de las areas de la Fundicion y Refinerias, asi como el de asegurar la salud, seguridad y los estandares ambientales a lo largo de un proceso de varios anos. Un detalle de las actividades que comprende esta fase puede apreciarse en la figura 6.5.1/1. Los controles de medio ambiente deberan establecerse antes del trabajo de desmantelamiento y demolicion y su objetivo sera el de minimizar el potencial de descar- PAMA COMPLEJO METALURGICO - LA OROYA Capitulo VI Pag 250. - -------------------------------------------------------------------------------- ga de desechos no tratados al medio ambiente y asegurar que se realice un plan de salud y seguridad antes del inicio de la demolicion. Sus actividades principales se indican en la figura 6.5.1/2. Debe senalarse que los controles de medio ambiente continuaran durante la etapa de post-cierre, con el proposito de garantizar el exito del cierre y de ser necesario se efectuaran correcciones o trabajos de mantenimiento. La fase de desmantelamiento y demolicion, cuyas actividades principales se indican en la figura 6.5.1/3, debera ser ejecutada de acuerdo con el plan maestro, teniendo en cuenta la posible reutilizacion de algunas edificaciones en actividades futuras. Para la fase de investigacion y recuperacion del area, solo quedaran algunos edificios, vias y algunas lineas ferreas, lo cual facilitara llevar a cabo las actividades mostradas en la figura 6.51/4, donde la contaminacion del suelo podra ser el aspecto mas serio para la recuperacion de las areas y el uso futuro del suelo. Uso que podria estar entre el industrial o el residencial-recreacional. 6.6 Presupuesto de inversiones El presupuesto de inversiones estimado, para la ejecucion del cierre total del complejo es el siguiente: - -------------------------------------------------------------------------------- DESCRIPCION MONTO (US$) - -------------------------------------------------------------------------------- 1.0 Desmontaje de Equipos 15 000 000 - -------------------------------------------------------------------------------- 1.0 Desmontaje de Estructuras Metalicas 19 000 000 - -------------------------------------------------------------------------------- 3.0 Demolicion de Obras Civiles 5 000 000 - -------------------------------------------------------------------------------- 4.0 Investigaciones y correccion del area 5 500 000 - -------------------------------------------------------------------------------- 5.0 Venta de eguipos y material de edificaciones recuperados (22 500 000) - -------------------------------------------------------------------------------- SUB-TOTAL 22 000 000 - -------------------------------------------------------------------------------- IMPREVISTOS 2 000 000 - -------------------------------------------------------------------------------- TOTAL 24 000 000 - -------------------------------------------------------------------------------- 6.7 Cronograma de ejecucion El cronogramna de ejecucion del proyecto se estima requerira de 70 meses, bajo el siguiente detalle: - -------------------------------------------------------------------------------- ACTIVIDAD TIEMPO (MESES) - -------------------------------------------------------------------------------- 1.0 Terminacion de los inventarios 1 - -------------------------------------------------------------------------------- 2.0 Establecimiento de controles ambientales 3 - -------------------------------------------------------------------------------- 3.0 Desmantelamiento y remocion de eguipos salvables 9 - -------------------------------------------------------------------------------- 4.0 Demolicion 9 - -------------------------------------------------------------------------------- 5.0 Investigaciones de sitio 12 - -------------------------------------------------------------------------------- 6.0 Recuperacion del sitlo 36 - -------------------------------------------------------------------------------- TOTAL 70 - -------------------------------------------------------------------------------- 6.8 Mitigacion propuesta De implementarse el cierre del Complejo, se producira una reduccion inmediata y de alta proporcion en cuanto a la cantidad de contaminantes que se descargan al ambiente. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo VI Pag 251. - -------------------------------------------------------------------------------- Conforme se aplique el plan maestro de actividades para este cierre, la contaminacion ira alcanzando niveles inferiores que estaran muy por debajo de los limites permisibles establecidos. Otro aspecto importante de mitigacion sera la recuperacion del area para permitir el uso aceptable de la tierra a futuro. La remediacion del medio ambiente contribuira a mejorar las condiciones de vida desde el punto de vista ambiental, no solo de La Oroya sino tambien en el cauce y valles del rio Mantaro aguas abajo. 6.9 Analisis economico Las caracteristicas propias de un Plan de Cierre, las cuales no estan involucradas directamente en el proceso productivo, no permiten definir para el Complejo Metalurgico de La Oroya un tipo de rentabilidad cuantificable en indices economicos.

PLAN DE MONITOREO DE EMISIONES Y EFLUENTES 7.1 Objetivo El plan de monitoreo de emisiones y efluentes tiene como objetivo cuantificar los resultados del Programa de Mitigacion, el mismo que tiene como proposito alcanzar las exigencias de ley. -- Para Emisiones: Resolucion Ministerial No. 315-96-EM/VMM (Niveles Maximos Permisibles de Elementos y Compuestos presentes en emisiones gaseosas provenientes de las actividades minero-metalurgicas - Anexo No. 1 y 3). -- Para Efluentes: Resolucion Ministerial No. 011-96-EM/VMM (Niveles Maximos Permisibles para Efluentes Liquidos minero-metalurgicos - Anexo No. 1 y 2). El plan de monitoreo considera reduccion de puntos de monitoreo debido a los proyectos de mitigacion, asi como sistemas de muestreos adecuados y analisis: mecanicos, fisicos y quimicos, residuos solidos y otros elementos, que puedan ser generados por las operaciones del Complejo Metalurgico. Asimismo, considera recopilacion de la informacion correspondiente para ser reportada a la Direccion General de Asuntos Ambientales (D.G.A.A.) del Ministerio de Energia y Minas. 7.2 Plan de Monitoreo El plan de monitoreo para emisiones y efluentes debera llevarse a cabo con los recursos disponibles y otros a incrementarse: - Recursos Humanos - Infraestructura y/o Equipos - Protocolos - Estaciones y/o Puntos de Monitoreo - Capacitacion 7.2.1 Recursos Humanos La ejecucion del Plan de Monitoreo a nivel de campo, estara a cargo de la Seccion de Pruebas de Control de la Direccion de Control de Procesos Metalurgicos de la Gerencia Central de Operaciones Metalurgicas. Esta ejecucion estara bajo la supervision directa de Ingenieros Metalurgistas. 7.2.2 Infraestructura y/o equipos. - Equipos con que cuenta Centromin Peru S.A.: 7.2.2.1 Para Emisiones Para determinar las emisiones gaseosas de la Fundicion se dispone de muestreadores neumaticos Sprague para el muestreo manual y bombas de vacio para el muestreo automatico, asimismo los flujos de gases se determinan con tubos pitot y medidores de tiraje Dwyer y los analisis de gas con un analizador electronico COSA y los analizadores quimicos Orsat y Orsat Universal. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo VII Pag 257. - -------------------------------------------------------------------------------- 7.2.2.2 Para Calidad del Aire Para monitorear la calidad del aire se dispone de dos monitores de gases (S0(2)), marca Kimoto de fabricacion Japonesa, tipo 331 B, para evaluar concentraciones en escalas de ppb. El principio de funcionamiento del detector es el fenomeno de conductividad. Al oxidarse el SO(2) en el medio receptor, genera microcorrientes de energia electrica que son registrados por sistemas electronicos y entregados directamente en cifras, para lectura o impresora. Tambien detecta el material particulado en micrograma/m(3), con registro automatico, para lo cual tiene una cinta de papel en movimiento controlado, en este captor, el aire ambiental es forzado a traves de la cinta-filtro y deja en ella materiales que manchan el papel. Estas manchas cuyas densidades (y color) son variables segun los contenidos del aire muestreados; son "leidas" por un dispositivo de rayos (beta), las distintas lecturas dan los "indices de la suciedad del aire", ademas de la masa de particulas. En estas muestras tambien pueden hacerse determinaciones por elementos quimicos especificos (ejemplo As), previo tratamiento analitico en Laboratorio. Se dispone tambien de dos monitores de gases (SO(2)), marca Kimoto de fabricacion Japonesa, tipo 332 TW. capaces de evaluar concentraciones en ppb, direccion y velocidad de viento con registro automatico y un monitor de gases (SO(2)), marca Kimoto de fabricacion Japonesa, tipo DKK, capaz de evaluar concentraciones en ppb. Para el monitoreo de calidad de aire se dispone de cuatro muestreadores de alto volumen (High-Vol) KIMOTO portatiles que se usan en forma rotativa en todas las estaciones, para medir la concentracion de materiales particulados flotantes o polvo ambiental acumulado en un papel filtro para sus respectivas determinaciones ponderadas de la muestra total, con sus analisis de contenido de metales pesados (Pb, Cd) y Arsenico (As). 7.2.2.3 Para Efluentes Pan realizar el monitoreo de emisiones de efluentes liquidos y calidad de aguas, se dispone de un equipo Orion para determinar la temperatura (degree C), pH, Eh en mV (milivoltios), un TOA para la conductividad en microS/cm. de un filtro de aire presion Denver para la separacion de solidos TSS (total de solidos en suspension) , 7 muestreadores automaticos IS-CO para las estaciones de monitoreo con mayor efecto contaminante, un medidor de flujo electronico Kay-Ray, un conservador de muestras APIN, pan evitar los cambios fisicos y quimcos, durante el periodo de composito, asimismo depositos de plasticos graduados (baldes) para la medicion de flujos, an cronometro CASIO y depositos oscuros de un galon para almacenar las muestras. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo VII Pag 258. - -------------------------------------------------------------------------------- 7.2.2.4 Equipos Nuevos a ser Adquiridos Con la adquisicion de una nueva estacion meteorologica se obtendra la informacion requerida que sera usada en el modelo matematico ISC-3 (Industrial Source Complex Model, Version-3) de la Agencia de Proteccion Ambiental de los E.E. U.U.(EPA) y con lo cual se podra obtener informacion de la simulacion de la dispersion de emisiones. Con la modernizacion de los equipos de monitoreo, para la calidad de aire y emisiones gaseosos, se obtendra la informacion a tiempo real de las concentraciones de los contaminantes que permita tomar medidas correctivas en las operaciones. 7.2.3 Protocolos Existentes 7.2.3.1 Para Emisiones v Calidad de Aire El monitoreo de la calidad de aire y de emisiones se realiza de acuerdo al Protocolo de Monitoreo de Calidad de Aire y Emisiones de la Direccion General de Asuntos Ambientales del Ministerio de Energia y Minas. Segun este protocolo se han determinado las estaciones de monitoreo de calidad de aire y de emisiones, para lo cual se ha considerado un monitoreo meteorologico, ya que los fenomenos atmosfericos cumplen un papel importante y complejo en la determinacion de la dispersion de los agentes contaminantes y la calidad de aire resultante, asi como: la estabilidad atmosferica, la velocidad y direccion de viento y la temperatura del aire, para lo cual se cuenta con una estacion meteorologica. Se dispone de medidores de velocidad y direccion de viento en las estaciones de monitoreo y analizadores de SO(2) y material particulado en suspension de bajo y alto volumen. Estos equipos se calibran de acuerdo a un programa establecido; las muestras de SO(2), de material particulado en suspension, la velocidad y direccion de viento se toma en cada hora. Para las estaciones de monitoreo de emisiones se hace uso de los siguientes equipos para captacion de polvo: tubos de muestreo, camara de captacion de polvo en filtro de celulosa (tipo cartucho) eliminador de humedad y condensador, contador de gas (gasometro), bomba de aspiracion y balanza analitica electronica; para las mediciones de flujo de gas se tiene: tubos de pitot, tipo S., manometros y termometros, para la determinacion de la composicion de los gases se cuenta con analizadores electronico y quimicos, luego se colecta los datos y se hace los calculos respectivos y se prepara los informes. Para que los datos sean confiables, se tiene un programa de calibracion de estos equipos. Los compositos de estas muestras bien rotuladas son enviadas al Laboratorio para sus respectivos analisis. Por ultimo, se prepara los respectivos reportes y se hace las evaluaciones pertinentes para su presentacion al Ministerio de Energia y Minas. PAMA COMPLEJO METALURGICO - LA OROYA Capitulo VII Pag 259. - -------------------------------------------------------------------------------- 7.2.3.2 Para Calidad de Agua Los muestreos se realizan segun el Protocolo de Monitoreo de Calidad de Agua de la Direccion General de Asuntos Ambientales del Ministerio de Energia y Minas. De acuerdo a este Protocolo, se han establecido las Estaciones de Monitoreo en donde se identifican todas las fuentes contaminantes hacia el cuerpo receptor. Se ha considerado al complejo metalurgico como instalacion de procesamiento, que evacuan subproductos metalurgicos y residuos, asi como la descarga de aguas de desecho (incluyendo aguas servidas), donde se mide la calidad y cantidad de cada corriente. Estos efluentes liquidos se muestrean dos veces por semana para la evaluacion metalurgica, de igual manera se debera muestrear aguas arriba y aguas abajo del cuerpo receptor, con respecto a las instalaciones del procesamiento, en los analisis de agua se tiene parametros inorganicos: fisicos (solidos totales en suspension, temperatura, flujo, pH, Eh, conductividad; inorganicos-iones principales: solidos totales disueltos, cianuro, oxigeno disuelto, nitratos y sulfatos); inorganico-metales: As, Cu, Fe, Pb, y Zn y parametros organicos: coliformes fetales y totales. El muestreo que se realiza en los efluentes y rios es de muestras repetidas temporales por un periodo de un mes, por recoleccion a intervalos de tiempo (2 veces por semana), en frascos adecuados y bien limpios, determinando parametros inorganicos fisicos que son anotados debidamente. En el muestreo de rios se hace tomando una muestra repetida espacial en las 2 orillas del rio y en donde hay puentes se toma una muestra mas, compositandola en una sola muestra. Para obtener los resultados optimos, se realizan los analisis de muestras en blanco y duplicadas para tener garantia de calidad (QA) y se guarda un respaldo de las muestras para el control de calidad (QC). El composito de las muestras debidamente rotuladas se va guardando en una conservadora a una temperatura de 4\degree\C, en frascos frescos y oscuros para evitar cambios quimicos de la muestra. Por ultimo, se envian las muestras al Laboratorio y al obtener los resultados se hacen las respectivas evaluaciones comparando con datos anteriores y de otras estaciones. 7.2.3.3 Otros monitoreos Se implementara otros monitoreos para evaluar los resultados de los proyectos de mitigacion. 7.2.4 Estaciones y/o Puntos de Monitoreo Los puntos de monitoreo para efluentes liquidos podran sufrir cambios segun los proyectos de mitigacion segun el Capitulo 5. Por ejemplo, el caso de los efluentes liquidos. industriales, la descarga seria en un solo punto, segun el diagrama PAMA COMPLEJO METALURGICO - LA OROYA Capitulo VII Pag 260. - -------------------------------------------------------------------------------- 3.1.1/1, en el titulo 5.4.8. Estos cambios de puntos de muestreo se hara de conocimiento de las autoridades competentes. Actualmente las estaciones y/o puntos de monitoreo que controlan las emisiones gaseosas internamente y externamente, es como sigue: 7.2.4.1 Emisiones o Dentro de la Fundicion: (Ver Foto 4.1.1/1 - Cap.

OBJECTIVE The environmental remedy and management program (PAMA) revision and endorsement. 4. PAMA INFORMATION AND REQUIREMENTS VERIFICATION. 4.1. LA OROYA SMELTER undertakes the following industrial activities: o The concentrates benefit process is done by toasting, smelting, Zinc Leaching and , electrolytic refinery by casting. The final products and sub-products are commercialized in national markets and international markets. o The Metallurgical Complex takes energy from four hydroelectric centers of 183,4 Mw. using 53.8% of each that is 98,7 Mw o Hydrocarbons Storage and Use: It has fuel storage tanks: Residual Oil No. 5, Diesel, Gas, and 4.2 Effluent Monitoring 4.2.1. Contaminant Liquid Effluents According to The Air Quality and Effusions Protocol and The Complex Treatment Tonnage, it is necessary to take into consideration the implementation of at least one more Monitoring Station for Air Quality and Effusions to be able to complete the data that already exists. There are measurements for Dust and Gases at the complex interior. 4.2.2 Liquid Contaminant Effluents. To evaluate the water quality 40 station have been evaluated for the years 1994, 1995 and 1996. Seven of these results are relevant. It will be necessary to identify them through UTM coordinates. It will be also necessary to present a table that will summarize the location, parameters, frequency and analysis and measurement methods. 4.3. Evaluation and Analysis of the Environmental Impacts To mitigate the impacts PAMA introduces the following projects: o Construction of Sulfide Modules. o Management of the "Slag New System" ( Granulation Water ). o Treatment of the Arsenic Trioxide Deposits. o Treatment of the Ferrites de Zinc Dposits. o Re - forest for smoke affected area. o Treatment for Swage and garbage. 5. THE MITIGATION PAMA PROGRAMS It is not possible to give a good judgment related to the technology applied, execution time and investment needed due to the lack of projects. The estimated investment is $ 129 125 000 ( one hundred and twenty nine million one hundred twenty five thousand American Dollars). The mining - metallurgical mitigation projects established by PAMA should be executed in 10 years. It is necessary to complete with some other projects aiming to mitigate contamination. 6. PAMA COMMENTS o PAMA does not indicate the incidence of work sickness o The Contingency Plan is very generic. o PAMA visuals are not organized in adequate manner meaning the Tables and the photos as well as the Maps. 7. PAMA OPINION From the evaluation of The PAMA Report related to mining-metallurgical activities we have the following opinions are valid: o The identified Impacts as well as PAMA mitigation projects assure in part the environmental management at The Production Unit . Thus these observations must be complemented. This is what we inform for the pertinent objectives and we subscribe the PAMA. - ---------------------- Marcos Malaga Cruz Legal Representative TABLE OF CONTENTS EXECUTIVE SUMMARY I.

2.1.4. Residues Generating Sources, Treatment and Final Disposition. The following are the solid residues generators that are managed at at the metallurgical complex. The location of each of the sources is in Annex 4, treatment and final disposition see Table No.25 2.1.4.1. Copper Slag Reverber This solid residue is produced when mortar coming from the copper roasters melts. Two phases take place: First a very dense phase that is compound by sulfurous metals forming the matte and second a less dense phase containing the gangue or slag and the smelters. The slag is discharged at the opposite side from the burners, grained with high pressure water and sent to the slag deposit trough a cable car. Today, copper slag is deposited in Huanchan (a complex near by area) . It is estimated that it is possible to keep depositing in this area for a period of 5 to 10 years more. In Table 2.5 important residues characteristics can be appreciated. It is necessary to take into consideration table 2.6 to identify treatment codes and final state. See Picture 2.1.1 2.1.4.2 Lead Furnace Slag This solid residue is generated after the oxide melting and reduction process takes place, specially from lead and lead sulfate to metallic lead. The melted material is discharged to the settling tank to separate the slag from the lead matte. The slag exits to a granulation channel with high pressure water streams where it is dragged to the settling tanks and slag discharge to be sent to this material deposit by cable car. The slag is also deposited in Huanchan (near by area). It is estimated that it is possible to keep depositing in this area for a period of 5 to 10 years more. Table 2.5 presents important residues characteristics. Furthermore it is necessary to point out the quantity of copper and lead slag stored in Huanchan, approximately 10 000 00 t. See Picture 2.1.1 2.1.4.3 Arsenic Trioxide This residue is generated from roasting the powder recovered at the arsenic mixed with pyrite Cottrell. The arsenic vaporize and condense, the processed vapors pass to the warm arsenic Cottrell from there to the furnaces where the obtained product contains 81,5% of As2O3. Due to scarce sales the arsenic trioxide is a copper smelter marginal product. It is stored in a deposit named "Vado" located 10 km from La Oroya. Another old deposit is located near the "Malpaso" power-electric. Both deposits constitute sources of dust emissions to the environment, for this reason a number of treatment alternatives are been contemplated. The amount stored at the "Vado" Stock is 164 575 t, the table No. 2.5 presents some important residue characteristics, See Picture 2.1.1., a and b. 2.1.4.4 Zinc Leached Residues ( Zinc Ferrites) It is generated after the Zinc calcine leaching; the process is undertaken in agitators tanks where the used electrolytic, concentrated sulfuric acid ( if required) and the fine calcine are loaded. The iron is precipitated with manganese dioxide along with arsenic and antimony, etc. and the zinc ferrites remaining insoluble. The zinc ferrites with an 8% content of solids are pumped in a pulp form to the settling tank located in Huanchan. Leaving the solid part in the tanks and the liquid part discharged in the Mantaro River. Today the Zinc Ferrites deposit has 1 234 300 t, constituting a pollution source, specially in winter. (During the months of May through September). See Picture 2.1.3 2.1.4.5 Thallium Residues This solid residue is generated from the crude cadmium sponge at the cafdmium plant. The sponge is re-dissolved in sulfuric acid and the concentrated cadmium solution is purified by adding potassium permanganate , caustic soda and sodium carbonate with these elements iron and thallium precipitate. The produced material is transported by trucks to Huanchan deposit (Side No. 4 of the Zinc Ferrites deposit). 2.1.4.6 Industrial Waste The industrial waste generated at the Metallurgical Complex are classified. This project involves the solid combustible residues separation: wood, fabric, paper, oils, and grease which are not recommended to be flamed because it generates dangerous flammable products such as: plastics and resins. A burner is installed at the smelter and an other one is installed at the Huaymanta refinery They carry on a complete combustion operation. The industrial scrap iron is also picked out for recycle. 2.1.4.7 Manganese Dioxide This residue is generated in the zinc electrolytic cells in the following manner: o Through mud settling at the bottom of the cells which is produced during the zinc sulfate solution electrolysis process. The mud with manganese contents is extracted during the cell cleaning stage to be stored afterwards. o Through lead anodes washing. At the cell cleaning stage the lead anodes are washed with pressure water, the product is sent to the settling tank and the solids are subsequently stored. The residues obtained in both operations are stored in the Mantaro river basin.

The principal gas emissions contaminant is the SO2 , as a consequence of concentrates and fluxes treatment with high sulfur contents; also, the gas emissions bear lead, arsenic and cadmium particles among others. In general, the contaminants variety originated at the different operations and processes (annex 5) are discharged into the environment by three well defined sources. o The Principal Stack: which height is 167,5 meters, it is the major gas emitting source. o The Secondary Stacks: In a total of 95 units of a variety of dimensions (from 4 to 91 meters) and distributed in different circuits of the plant. o Undefined Sources that in accordance to the DGMAMEM are known as "Fugitive Emissions". The principal stack as it was already pointed out is a significant gas emitter. The so called "gas emission" is the mixture of gases, vapors, metallic fumes and grained material or dust that due to their components dimension are not affected by gravity and are integrate into the environment. Among the secondary stacks, the iron stack has been studied (91 meters height) and the coke plant (19 meters height). Some others have been characterized that are referred to in this study. The emissions by these stacks require a better definition. However, it has been observed that the majority of these stacks are not very harmful because they are combustion gases, water vapors and inert dust. In relation to the fugitive emissions, they escape directly to the environment. Its origin is diverse and, in higher and lower grades due to lack of good control in the process, lack of ventilation systems and / or micro-meteorology changes ( gust of wind, temperature, humidity); fugitive emissions are difficult to quantify because they are irregular and of quick dispersion. (Picture 2.1.5) Some of these emissions have an important negative action , since they could revert over the soil and liquid effluents making worse the contamination of these other two environment factors. The gas emissions generated by the smelter are detailed as follows: (Table 2.7) a) Copper Circuit Grained Material or Smelter Dust They are produced by solid mechanical haulage in the gases roasters, reverbers, and copper converter circuits. Around 97% of the grained material is recovered successively in the arsenic Cottrelles and central; the remaining 3% is evacuated through the main stack along with the main stack and other circuits gas emissions . The portions recovered at the Cottrelles return to the production circuit. Gas Residues The gas coming from the Roasters, Reverbers and Converters are directed to the main stack after passing through the Cottrelles. These gasses contain basically S02 and combustion gases. The quantity of SO2 originated in this circuit is approximately 508 t per day representing 53% of the total SO2 poured into the environment by the main stack. Emissions that Escape Directly to the Environment These emissions are produced at the preparation plant by solid material haulage outside the bells, this occurs basically because of the extractors insufficient capacity. At the Roaster Plant acid and solid emanations are reproduced discharging directly to the environment from the loading floor because of lack of room in the main evacuation duct. In a similar manner it has been observed that gas leaks and dust are generated in the calcine discharge operations in to the wagons; they are not captured by the control system bells. At the Reverber Furnace there is no longer a fugitive gas production because the ventilation system of the discharge opening, the slag, and the slag channel are connected to the iron stack. Acid Gases and Dust are also produced at the reverber loading floor because they lack ventilation hoods. The inadequate ventilation system of the Converters allows dust and acid emission to escape to the work environment during the cold re - circulating material loading. The combustion gases and the SO2 freely spread at the blister copper casting retention furnaces due to the lack of an entrapment system. Likewise, at the Arsenic Plant grain material containing trioxides escapes, covering the work environment due to the lack of a dust catching system during the unloading and shipping operations. b) Lead Circuit Grained Material or Smelter Dust They come from mechanic hauling of the solid fractions contained at the Blast Furnaces, the Skim Reverber, and the huge gas proportion of the Agglomeration Plant. The grain materials are retained at the Central Cottrell in a proportion that reaches 97% to be re-circulated at the Copper Circuit. The other 3% is evacuated by the main stack. Gases that come out from the Main Stack The most important ones are originated at the Agglomeration Plant, Blast Furnace, and the Skim Treatments. In the first case, the gas emissions are generated in the synthesizer machine conducted to the Central Cottrell where the metallic grain precipitate and the residual, along with the gases, continue through the main stack. Also, the gases and the particles formed in the Blast Furnace fusion process are directed to the Cottrell and from there to the main stack. The same process appears with the contaminants that come out from the skim treatment at the reverber furnace. The general balance neutral sulfur (S(Degree)) reveals that 30% of the SO2 formed and evacuated by the stack, comes from this circuit and that the 84% of the SO2 comes from the Agglomeration Plant. Gasses Generated in the Coke Plant The most important source of contamination in this unit is constituted by the coke retorts were the combustion gases are produced that are discharged in the environment through two stacks of 19 meters. (Picture 2.1.6.) Gases Emitted by the Secondary Stacks This gases have lower flows than the ones before as a consequence of the metallurgical discontinuous processes, incremented by flows coming from the dust catching system, combustion gases and cooling vapors. Gases that are Discharged Directly to the Environment The emissions in this case, are basically constituted by particles and fine dust originated in the hauling and transfer of synthesized material (thick and thin). The route also produces weak emissions of SO2 from gases that exit the still warm sinter where they were trapped. It has been observed that due to the lack of fans and due to the false air catching, a considerable part of lead part is not conducted by the stack gasses. Another contamination source in this circuit is the retorts discharge operation. This operation is small, but emits gases, dust and vapors in significant quantities which end up around the work areas. c) Zinc Circuit Gases Channeled through The Principal Stack It has two flows: A group of gas emissions that are originated in the roaster process of the fluid bed system (FBR) and the other group originated in the turbulent bed (TLR). In the first case, the emissions pass to the boiler to pass afterwards to the Central Cottrell from where the gases with SO2 are discharged into the atmosphere through the Principal Stack. From the TLR the gasses pass first to the heat recovering system (La Mont boiler). and from there to the particle recovering system. The clean gases are raw material for the Sulfuric Acid Plant. The residual gasses are discharged via the main stack. The sulfur general balance (S(Degree)) reveals that the 7.4% of the SO2 evacuated by the main stack comes from this circuit and 9% of the SO2 coming from the TLR changes into H2SO4. Gasses Channeled through Secondary Stacks In this aspect it is important to consider that the limited altitude of the Cadmium Plant Stacks can originate solid metallic residues precipitation in nearby areas. Gasses Directly Discharged into the Environment In the neutral leaching and purification stages acid vapors are generated due to the temperature conditions and the treatment tank contents. These contaminants also are produced in the house tank during electrodeposition in a higher magnitude than in other areas. The acid vapors also are present during the pellets drying at the Roaster Plant fluid bed. The measurements taken by the Ventilation Department reveal that at the TLR Plant environment there are not recommendable Zinc and Lead Concentrations in form of "flying dust". The precipitation of these materials to the Zinc Circuit Floor is visible originating alterations in the liquid effluents that flow by the open channels. Finally, at the Zinc Circuit gases and particles formed during the discharge of the iron slag to the Kiln Furnace exit to the environment, affecting as in other areas the liquid effluents. d) Anode Residual Plant and Silver Refinery A peculiar characteristic of this plant is the variety of the processes and reactors employed, as well as the discontinuous sequence of the production processes. Consequently, the identification and monitoring of the various characteristics and complex emissions make it difficult to evaluate. Gaseous Emissions of the Main Stack The gas material originated in the reverber fusion processes are taken through the electrostatic processes where the solids are recovered . The gasses are taken to the environment though the main stack. The gasses and dust coming from the discharge opening of the fusion reverber and reduction follow the same path. The particles and acid gasses (nitric) produced during the refined silver crystals fusion are cachet to be derived to the Copper Reverber duct and from there to the to the central units of electrostatic precipitation units following the residual flow towards the open environment. From the Silver Refinery partition processes acid vapors are generated. Acid vapors from the kettles and the silver cementation tanks that are caught by the exhaust hoods and conducted to the Central Cottrell. The S(Degree) general balance in this area reveals that the 9,5% of the SO2 emitted by the main stack is product of the circuit in reference. Emissions by the Secondary Stack They are emitted through local stacks in minor flows. Direct Leaking to the Environment In the reverber area there are two important gas exits that increase during the smelted materials decanting into the converters. At the Anode Residues Plant the ventilation systems show a visible deficiency, facilitating abundant diffuse emissions at different operation stages. e) Copper and Lead Refinery Atmospheric Emissions The electrolitic refining processes used in this unit require many operations with temperature changes, in such a way that the principal gas emissions are water vapors loaded with higher and lower grades of specific contaminants. At the anode mud leaching and washing and at the Cu and Pb cementation a water vapors loaded with acids and sulfate (H2SO4, HF, H2SiF6, CuSO4) drag along in mist or mechanically. At the cooling operations ( of the copper bars, wires, etc.) a high quantity of water vapors with no or very little extraneous materials are produced. During the Lead fusion, metallic vapors break off to the environment, although their course (diffusion) normally should be of a short distance because when cooling they will precipitate in form of particles. Certainly, there are combustion gasses with a typical composition which are evacuated independently from the gas processes. In general the are no treatment systems for any of the gas emissions referred to. There is no detailed information about flows and components. At the work place interior it is easy to perceive the typical odors of the refining electrolytes, probably due to the little efficiency of the ventilation systems. These gas emissions are potential contaminants of the Yauli river because during rainy season they are inevitably dragged into the soil. To have a qualitative idea about the contaminants apportion by each refinery, a reference to there processes and most of their characteristic operations has been made, including the control systems at 19 ventilation stacks. Table 2.7 J, shows in detail the Copper and Lead Smelter and Zinc Refinery (annex 5) secondary emissions sources with some of their physical and chemical characteristics. In drawing 2.2 it can be observed schematically gas and dust handling at the copper and lead smelter. 2.1.6 Contaminants Receptors The liquid effluents are discharged to the Yauli and the Mantaro Rivers. The gas emissions have an influence in the areas near the smelter (annex 10) Solid residues are stored in the river basin nearby areas. 2.2 Physical Environment 2.2.1 Topography It is a very uneven topography formed by huge depressions. The Yauli river is a Mantaro tributary. In its course it passes through a flat topography belt , where a number of towns have been built. The Mataro River crosses La Oroya City from North to South forming a very narrow valley. Down river passing La Oroya toward the Huancayo route, the valley becomes more and more narrow and huge rocks predominate. In the smelters high part by the Mataro left margin the topography becomes flat and with signs of heavy rain, at the very high part the topography is again very uneven. The topography map (annex No.7) presents a description of the topography at the Metallurgic Complex La Oroya influenced area. (annex No.7) 2.2.2 Weather and Meteorology 2.2.2.1. Weather The weather at La Oroya and surroundings is cold and with two well defined seasons: The humid season is between the moths of November to April with liquid precipitation and some times solid precipitation ( snow and hail). The dry season runs during the rest of the year. The precipitation is channeled through small fractures as small tributary creeks and or to the Mantaro River which happens to be the regional collector. It is important to point out that the morning wind (between 7 and 10 am) flows from North to South of the Mantaro Valley , after 10 a.m. it turns around South to North. 2.2.2.2. Meteorology The meteorology characteristics are of great importance in the atmospheric contamination phenomenon and for its effects. The information gathering in relation to the meteorological parameters at La Oroya is given to three stations. The first one is located in the smelter zone and the other two at the Cushurupampa area ( Not at the smelter) and Hanchan ( South East from the smelter), coinciding with the air quality monitoring stations. The Smelter Meteorological Station is the most complete in terms of the number of parameters evaluated. Precipitation (rain), environment temperature, humidity and barometric pressure are measured since 1925. The results obtained are not of exclusive use of Centromin . The pre-established continuous information is shared with the official meteorological office of the country. In other words it is part of the National Meteorological and Hydrology Service, called SENAMHI, operating under these offices rules. o Wind Speed and Direction The respective data is shown in Table 2.8. The analysis of this data presents characteristics that are easy to appreciate such as the wind direction. The wind roses (Drawing 2.3, 2.4 and 2.4 A) for the two urban stations show clearly the lack of winds. The evaluated directions form practically the complete wind roses, meaning that the generation of the winds and its course occurs in all possible direction. Relating this phenomenon with the contaminant distribution in a first approach, it results easy to understand that there are not zones that are continuously exposed, but that that the diffusion moves "from here to there", according to the dominant circumstances, tending to be stable over the narrow part of the Mantaro - Yauli Basin in contribution with other contaminant phenomena such as the atmospheric stability. Analyzing the Tables and the Drawings that show the speed average rate, it can be appreciated winds below the 2 m/ second that in the contamination area are considered less favorable since they do not allow "Barriadas" of desirable air. The Huanchan wind rose (Drawing 2.3) has a difference since there it can be understood that the winds go to the South West zones. ( river down from the Mantaro River waters), which results favorable respect to the ones going to the areas less populated. A very important aspect that deserves attention in the micro-meteorological phenomenon and much more directly related to the winds is the orographic influence in the area. The winds behavior in La Oroya atmosphere seems to be conditioned in a great part by the abrupt orography that limits the work and urban zones. o Precipitation There is a Smelter station and a sub-station at Mayupampa for the pluvial measurements. The average values show 568.10 mm of H2O for the Smelter Station, in a period of 72 years and 563.70 at Mayupampa in 39 years.(Table 2.9) Normally, the precipitation (liquids such as the rain and solids such as snow) at the atmospheric contamination zones are considered benign because they clean the environment air. However, in La Oroya it is related to a negative effect because they could constitute an additional source of contamination for the Mataro River. This due to the "Washing" = "Lavado" action which occurs over surfaces that have accumulated contaminants throughout time and are dissolved and dragged to the river. o Relative Humidity and Temperatures The parameters values obtained at the La Oroya Station (Smelter) show that humidity and temperatures are not strictly the same neither adjust to the common understanding that the Andes region is a cold and dry area. Table No. 2.10 and Drawing 2.5 illustrates these values showing that temperatures over the 20 (Degree) (typical of warm areas) are not rare and that the environment has a humidity that is over the 70%. In any case, there are additional data regarding the meteorological conditions of the area that are complicated. In group they are singular circumstances that generate contradictory conditions prone or not to environment contamination. o Barometric Pressure At the Main Station (Smelter) the barometric pressures are measured expressing them in Kpa (pascal kilos). Their average monthly values are reported in table 2.11. These values in the atmospheric contamination area have multiple applications in gas calculus, that necessarily involve pressures, volumes and temperatures. 2.2.3. Environmental Air Quality It has been designed and put into operation an extensive Monitoring Program regarding The Environment Air Quality that comprises: Field Works a) Measurements and Sampling of : Sulfurous gasses, total grained material (TGM) and heavy metals in five stations located at the representative areas, comprising about 10 kilometers of the Production Unit, La Oroya Smelter. b) Meteorological Parameters Monitoring Stations coinciding with the ones above and others. c) Field Observations. Surveillance. Laboratory Works a) Analysis (micro-analysis), chemical physical, through classic and instrumental methods. b) Equipment Calibration and Reagents Preparation. c) Data collected Cabinet Works a) Information Gathering b) Collecting and Treatment of data obtained at the field and laboratory. c) Reports Structure Monitoring Stations The monitoring stations have been located considering factors such as the electric energy facilities, access, surveillance and the Yauli - Mantaro river basins situation, among others. ( Table 2.12 and Annex 8). The following describes each of the stations with the most important characteristics as well as their equipment. a) Huanchan Station Located near the Cu and Pb slag deposits, 30 meters form the slag inlet. Tower 16 at 2 kilometers from the main stack in the "Y" strip of the Huancayo road. It is located with an (SO2) gas monitor, Kimoto Japanese brand, type 332 - TW, capable of evaluating ppb scale concentrations, counting with an automatic registry. The detector functioning principle is the conductive phenomenon. When SO 2 oxidizes at the reception area, it generates electric energy micro-currents that are registered by electronic system and taken directly in figures to be read and printed. This same unit is capable of register meteorological measurements basically in the wind direction. The station is completed by a high volume portable monitor (Hi-Vol) that is able to attract floating grained materials or environment dust in a fine paper thus being able to make high praise conclusions regarding the total mass captured or specific elements evaluations such as the bio-accumulated heavy metal contents. b) Workers Union Station Located at the urban zone (Old La Oroya). At the second plant of the companies workers union. Is the nearest to the principal source in reference, only 8 kilometers from the principal stack. This station is also equipped with an SO2 registry unit, "Kimoto" brand, but the type is 331-B, different than that one mentioned above does not assume meteorological registries, on the other hand it has a paper tape of controlled movement. At this catching point the environment air is forced through a filter type and leaves in it materials that stain the paper. These stains densities and color are variable according to the monitored air . They are read by a rays artifact ### (beta) The different readings give air dirt indexes and the mass particles. From these sample conclusions can be made about specific chemical elements (example As), previous laboratory analysis. c) Inca Hotel Station Is located 2 kilometers from the point of reference, located in the "Y" strip of the Cerro de Pasco road. The equipment has a Kimoto 331 Monitor and it is located at the Hotel's roof. The samples are also completed with a high volume equipment (Hi - Vol), and a sampler for grained materials that are not settled. d) Cushurupampa Station It is located 3 kilometers from the main stack in the "Y" strip of the Lima road. It has a Kimoto Monitor type 332 - TW and the Hi Vol. e) Casaracra Station It is distant. Located in the fish farm with the same name. At 10 kilometers from the central reference, in the "Y" strip of the rail road way and Cerro de Pasco road. As a DKK monitor to exclusively determine SO2. This monitor is based on the same sampling principle of the Kimoto. It does not give figure results, but graphic ones that require processes to get to the number results. Evaluations and Results The "environment air quality" evaluated contaminants at the monitors described above comprise the sulfurous gasses, which are expressed in SO2, the grain materials in suspension (MPS), the MPS metallic contents (As, Pb and Cd) and the wind speed. The results of these evaluations done at the above described stations are shown in Table 2.13. Grained Materials in Suspension (MPS) The grained contaminants evaluation is undertaken by two independent methods, but at the same sampling stations, this makes it interesting to look at them comparatively. The Kimoto 331 - TW as described above is capable of evaluating the MPS like the Hi Vol equipment. However, the difference is that the Hi - Vol manages high volumes of air, filtering the totality of the MPS in a 24 hour or more continuous period. While the tape samplings make a sequence sampling every 3 minutes, obtaining as consequence maximum and minimum averages. More importantly is that in the tape or stain paper method the evaluated particles are only a fraction of a smaller dimension than 10 microns, known as PM10. Meaning that from the totality of floating particles in the air the equipment is capable of discriminating (through a Cyclone system) the PM10 portions, known as "breading particles", for this reason it is valuable for the general public health. The Hi - Vol as it was said before collects all non settling material among which particles bigger than 10 microns are abundant. MPS Metallic Contents From the MPS samplings done by the paper tape method or by the Hi Vol method determinations can be made to detect the 3 risky elements (As, Pb and Cd) that are always present in the mining operations like the Centromin mining operation. These determinations are done through analytical laboratory procedures in monthly representative arrangements. 2.2.4 Geology and Seismic Conditions 2.2.4.1 La Oroya Geology The older rocks at the La Oroya surroundings are the ones that belong to the Pucara Group from the Jurassic Triassic age, principally composed of clear gray or white calcite, that must be overlaying the Mitu Group rocks from the Permian age. Goyllarisquizga Group of rocks are also present composed of red lutite and sandy, calcite, inter-stratified with basaltic layers and diabases Over these rocks it is found the Machay Group composed of gray bluish calcite and bituminous coming from the Pariatambo formation and the clear calcite, shales, limes, and phosphatic from the Chulec formation. South from La Oroya there are flourishing Red Coats from the Tertiary age, covering this flourishing there are a series of quaternary deposits distinguishing the following: a) Alluvial Deposits These irregular deposits are found at the Mantaro River and Yauli River forming terraces of different ages and dimensions in the quaternary. La Oroya Smelter and the Huaymanta refinery are sitting on this type of deposits. The fragments dimensions vary among blocks, gravels, and some sand. The composition of these materials is variable, sandy, etc. b) Pluvial - Glacial Deposits This type of deposits are located in the high parts of the old glaciers, in most of the cases there are only remains of the old big deposits. c) Colluvial Deposits These deposits are formed by steep slope rock banks that have been formed by rock erosion. They are small and irregular deposits. d) Elluvial Deposits In some parts it is possible to encounter rocks that are transforming the soil and some small deposits that originate the soils. Fractures and Folding The Mantaro river course adjacent rocks are strongly folded with a near to vertical dipping and in some cases they have been dislocated forming regional fractures. South to North East form the river the folding eases, forming ample anticlynals and sinclynals. Geomorphology At the La Oroya Metallurgical Complex some geomorphologic characteristics can be distinguished such as: The Mantaro river with some tributaries like the Yauli river, Shinchamachay, Huashango (Paccha), Pacchapata, ( Old La Oroya) , rio Seco, and some other small ravines that have formed its course on calcareous rocks, sandy rocks, shales, etc. At the Mantaro river and Yauli river old courses, pluvial terraces and some chemical precipitation deposits can be observed; such as Sacco - Tambo deposits, Shincamachay, Tishgo and Mantaro river joining point and some others much smaller like Old Oroya (covered with population) The altitude varies around La Oroya between 3, 600 to 4, 600 m. a. s. l.. The Smelter and Refinery are located at an average altitude of 3, 700 m. a. s. l. The Fractures (erosion fractures) produced by acid rain at La Oroya surroundings are very much visible. Especially , at the soil surface that has no natural vegetation. (so called Ichu). This erosive effect is intense at the Smelter surroundings and diminishes as it gets farther from the center. 2.24.2. Seismic Activity From the Tectonic point of view, La Oroya metallurgical complex is located in Zone 1 (National Construction Rules), corresponding to a high seismic area . It indicates that to build it is necessary to take into consideration the seismic parameters that the rules established, the buildings must be 2 floors or lower. 2.2.5. Soils Evaluation and Analysis of Soils and Water The study and evaluation of this natural resource is very important. They are studied in their physical, chemical and biological aspects. This studies have been performed on samples that have been taken at the affected zones as well as at the nearby areas. The analysis results are shown in Table 2.14, indicating that the soils have been impoverished by the washing that has been taking place during the years, having no vegetal coverings. There is no nitrogenous presence. The discharge solution is being re-circulated at the lead refinery operations. After the cathode disposition period required passes, the cathodes are removed from the dispositions cells to the washing to recover the electrolytic and then to be smelted at the three pans of 160 tons capacity, which are heated with oil. The smelted lead is heated up to 450 (Degree) centigrade and vigorously shaken with sodium hydroxide (NaOH) to skim the remaining arsenic, antimony and tin. The refined lead is cast into 46 kg bars to be commercialized. The hydrofluorsilicic acid required for the electrolysis process is fabricated by making the calcium fluoride (Ca F2)) and the sulfuric acid (H2SO4) react, to obtain hydrous fluoride acid (HF), which subsequently will react with the fine silica (Si O2) in a reactor. The solid (Ca SO4) is discharged directly to Yauli river. The option of building fields for this product is being considered. 2.3 Biological Habitat 2.3.1 Characterization Serrania Esteparia's bioregion covers from the La Libertad department to the north of Chile, in the Occidental Andes, around 1000 to 3800 a.s.l. with an interesting ecological formation characterized by its own climatic, edaphic, flora, and fauna factors. It takes the name of "Serrania" because of its most outstanding vegetal formations. It presents a very different climate to that of the coastal desert and to that of the Puna with which it limits to the west and east respectively. (Fig 2.6) 2.3.1.1 Terrestrial Ecosystem Characterized by the presence of a vegetation that forms a steppe of gramineous, Lupinus communities, some herbaceous plants of the Genera Baccharis, Polylepis, Buddelia, Alnus which are associated with gramineus such as (Stipa ichu, Stipa bhrachyphylla, Calamagrostis vicunarum, Calamagrostis antoniana, and Festuca heterophylla which constitute natural grass. The fauna is represented by the "Vizcacha" (Lagidium puna). The fauna in this zone is highly influenced by the elements of the Puna allowing the species of the serrania esteparia to reach its maximum distribution. In the Avifauna we can point out the presence of the "tortolita peruana" (Euphelia cruziana), the humming birds (Myrtis fanny) and (Thaumastura cora), the "negro" (Dives warszewiezi), the "tordo negro" (Molothrus bonariensis), the "Chisco" (Mimus longicaudatus), etc. 2.3.1.2 Aquatic Ecosystem The rivers in the occidental part are of rapids, and torrential waters, diminishing their temperature with the height that brings them brings as a consequence interesting zones of habitats among which we can mention rivers, Andean rivulets, earth and stone cliffs, stone beaches, rocky coasts, river borders with low vegetation. Of the most characteristic plants of this ecosystem, we will mention the "Pato de los torrentes" (Merganetta armata), and the "Mirlo acuatico" (Cinclus lencocephalus) which prefer rivers and rapid crystal clear ribulets. Among the amphibians, the most frequent are the "Sapo comun" (Bufo spinolusus), as well as the Telematobius jelskii and Telematobius runac. Little has been studied about the native fishes, but we can mention the "Chalwa" (Oretias spp.) and introduced as Salmo spp. 2.3.2 Ecosystems in the UDP The metallurgical complex is located in a rift formed by the Mantaro and Yauli rivers basins at 3800 a.s.l. The populated centers and farming zones are located near the basins of the Yauli and Tishgo rivers. A description of the terrestrial ecosystems in a 10 km. radius with the principal stack as its locus was made. 2.3.2.1 Terrestrial Ecosystem The Oroya factory is located inside of the andean valleys, with a surface area of 420 km(2), and geographically it occupies the occidental parts of the Andes with its center's height between 3700 and 3800 m.s.n.m. The topographical relief is shaped by strong slopes and acidic soils with reddish or brownish tones. There is very few fertile (combisoles districos) and eutric (fertile). Flora and fauna are very reduced or almost non-present because of the toxic action of the smoke of the plant; in table 2.15 we can observe the chemical analysis of the plants. (Picture 2.3.0) 10 Km. north of La Oroya is found the climate station of Casaracra. The circumvent area presents different characteristics to those described above. The scenery is constituted by gramineas y herbaceous of perennial habits that are dominant, such as Festuca heterophylla and Stipa ichu, because of prolific grazing the "Choca" (Chuquiragua huamanpinta), "Caqui Caqui" (Adesmia spinosisima) and some cactuses. (Picture 2.3.1) The grazing fauna there is sheep and cows. The birds are very scarce and can point out the "gaviota de la puna" (Larus serranus) Puna seagull In all the covered terrain, it was observed bushy species planted by reforesting such as the "colle" (Buddleia coriacea), the "Polylepis racemora." Also have been identified the "retama" and the "maguey" (Agave americana). From La Oroya to the south and bordering the mantaro river and in a 7 km. radius cannot be observed typical vegetation of the region except for Stipa ichu in very scarce amounts because of the smoke of the factory. From that region on, one can observe more populated vegetation as well as the high parts and the river, gramineas such as Festuca sp. and Stupa ichu. Also some species such as Quishuar and some cactuses. (Picture 2.3.2) No fauna representatives have been found. In the high parts, to the west of La Oroya (Approximately at 4000 a.s.l. ) can be seen the effects of the smoke of the factory on the ecosystem. It's been calculated an area of 3829 hectares where no flora nor fauna exists and can be seen the direct effects on the soil (Picture 2.3.3). On the middle part of the Huaynacancha valley exists a small lake formed by the thaw and rain where some vicunas drink water and where some birds like the "Huallata" or "Washwa" rest and it forms very scarse vegetation species like the almohadillas and gramineas. In the city one can appreciate the reforestation, in front of the Inca hotel, to the Centromin offices and in the villages with species like the Kolle, Quinual, Cypress, Quishuar, etc. 2.3.2.2 Aquatic Ecosystem a) Lotic Environment : Tishgo, Mantaro, and Yauli rivers The Tishgo river joins the Mantaro around the Casaracra Hacienda and their waters are used, after domestic use treatment, in the agriculture of the "trucha arco iris," - Trout - though for a while no fish species nor any other organism hasn't been reported. The river vegetation is formed mainly by gramineous. The Mantaro river runs from north to south, and brings in its flow high concentrations of pollutants and when passes through La Oroya it receives effluents from the lead refinery, from the water effluence of foul dirt granulation of copper and lead, from the principal channel No. 2 of the copper and lead smelting, from the solutions of the electrolytic plants of zinc, from the principal channel No. 1, from the parallel channel at point 135 and from the zinc ferrites effluent , as well as from the Yauli river that in its path also brings tailings and other contaminants. In both water bodies, no representative organisms from the flora and fauna have been observed except for the "gaviota de la puna" (Lorus serranus) and the "Huallata. The following are the values of the monitoring of the Tishgo, Yauli and Mantaro rivers. Table 2.16 It can be appreciated, that the Yauli and Mantaro rivers are contaminated with lead concentrations far over the Maximum Permissible Limits, cadmium, considered as one of the most dangerous elements is also reported in the Mantaro. Iron concentrations increase in the Mantaro on its path along the smelting plant, manganese is increasing five times its concentration in its path along the smelting plant, and arsenic is also present. Also, both rivers receive domestic emissions from all the population. 2.3.3 Endangered Species or on the brink of extinction In the Esteparia serrania, the intense and disordered grazing practice destroy the wild vegetation impeding natural regeneration and causing soil erosion. For the lack of vegetal cover, this zone is very prone to slides and floods "huaycos" in rainy seasons. The main cause for the disappearance of the species of this zone, flora as well as fauna, specially the endemic that present restricted distribution, is the destruction of the habitat, because of the loss of natural vegetation, as well as the contamination caused by the mine discharges in the water and atmospheric bodies. 2.4 Socio-Economic Environment 2.4.1 Socio-economic environment component description 2.4.1.1 Location and description of the UDP as a Mining Settlement and the Human Settlements of its surroundings o The UDP installations at La Oroya are located in the City of La Oroya The main populated centers are located in the immediate vicinity are: In the road that connects to Huancayo: The Huari Community, Hacienda Quiulla. In the road to Lima: the Huaynacancha Community. In the road to the Tarma exit are: The Antahuaro Hacienda and after Paccha, the Casaracra zone. In the Oroya - Cerro de Pasco route are eight more villages. It can be observed in a comparative way the demographic coefficients: Main Demographic Indicators - La Oroya

Source INEI As shown, the districts of La Oroya and Sta. Rosa de Sacco compose the 64.10% of the total population of the Yauli province. These are highly urbanized districts. With respect to the workers of the company, we find that 92% are married and proceed in their majority from the central zones of the country: Junin (79%), Cerro de Pasco (5%), Huancavelica (5%), other (11%). 33% of the workers have between 1 and 3 children and a 40% between 4 and 5 children. Also, 90,4% of the wives of the workers live in La Oroya. Of the 3215 workers depend economically 13728 people. 43% of the workers are between 31 and 45 years of age, and 32% more than 46. 63% of the workers possess high school education. On the other hand we must point out that the demographic growth in La Oroya continues to show a negative rate with respect to 1981. The diminishing of the population of La Oroya in the 81-93 period (-1.4) is due essentially to the rationalization of personnel policies that Centromin implemented in the mining crisis times and the privatization process. It exists, on the other hand, a floating population of 2444 people that travel frequently to La Oroya for commercial resons. La Oroya is divided into 2 big sectors: 1) La Oroya Antigua, in the exit to Huancayo zone in front of the smelting plant in the left margin of the Mantaro river. It's part of the areas that surround the highway, which are plains, and circumventing streets that extend to the mountains of pronounced cliffs; with streets, with no planning, it's shape is irregular and disordered. The constructions are very old and in a state of advanced decay. The occupation of the urban soil is saturated and prone to the slum process and tugurizacion by means of numerous streets. The area is essentially made of huts but also small establishments, two shopping marts, a church, a state high school, three schools, and a private high school. In the zone there is also neighborhood junctions, the main ones being: Mayta Capac, San Luis, Tayaupata and Plaza Libertad. They are inhabited essentially by particular inhabitants. 2) La Oroya Nueva, in the right margin of the Mantaro river and the zone where the company installations are located, in front of La Oroya Antigua, it extends towards the exit zone towards Tarma, and the one that leads to Lima. o The zone with the route to Lima extends towards the Paccha District and the outskirts towards Casaracra. In this sector are located the "Junin" hotel, the Club, and the Hotel Inca. The Hydroelectric plant of La Oroya and the Chulec sector, (picture 2.4.1.) privileged zone for its urban planning, streets, asphalted with unipersonal houses (chalet style) dedicated to the Centromin staff possess a sport center and a golf club. Here is located the Chulec Hospital that also belongs to the company and beyond the Mayupampa high school for the Staff's children and Centromin functionaries. o In front of Chulec on the other side of the river is located the Asentamiento Humano: Juan Pablo II that has a population coming from Tarma and Jauja and company workers. They possess 2-story houses of noble material but the streets are not useful for driving vehicles. We also find the Shica Machay settling. All through the road few huts are found, some businesses (grocery stores, restaurants, etc.), until one reaches Paccha 1 Km from La Oroya, District inhabited by farmers and ranchers of the communities of the zone. o The route goes on until Casaracra with virtually empty households. o In the Lima route zone, one finds the majority of the Centromin's worker's living areas. Transcribimos the following sectorization given by Centromin. (Figure 2.9)

The Calle Lima, that's the main street of this sector groups the Centromin's worker's and employee's households, great quantities of establishments, most of them stands and ambulant ones. The zone has a market. In the Alto Marcavalle zone (Picture 2.4.2) in the Yantacancha mountain that belongs to the Santa Rosa de Sacci district is produced a phenomenon that typicalizes the urbanization process of the population belts that surround La Oroya city and is constituted by the AA.HH. Tambo del Sol (Villa Sol), or Muruguay, Maria Concepcion, and Tacarpana. The four zones present similar characteristics and are near to one another having common services such as a satellite dish, a radio station (Super A.M.) and a stadium. The biggest is "Tambo del Sol;" 90% of the inhabitants are Centromin workers, they are here proprietors of 200 m2 lots with two-story adobe houses, with house small farm and animal rising. It possess 130 families and all the land is occupied. The settlers, to be able to obtain land, it was constituted in integrated Nuevos Comuneros to the Sana Rosa de Sacco community and began this process in 1981. (Picture 2.4.3) 11 Km from La Oroya route towards Lima are found the Curipata Household project, sponsored by Centromin for its workers. It is located besides the highway in a plain zone, and well planned (Postal, Stadium, High School, Church, Market projects, etc ). Even though the facilities that were given by the company, the majority of the people has left the land, because of its long distance from La Oroya (20 minutes) or for their lot being too close to the mountain that limits the amount of expansion (between 500 and 600 lots). (Picture 2.4.4) With respect to the Operaciones de Cetromin UDP la Oroya sector, it is located scattered in a more or less ample zone. (Figures 2.9 and 2.10), this way: o In the route to Lima, along the Carretera Central, and the Yauli River, in the Huaymanta sector are located the storehouse, the Alambron copper factory, the copper and lead refinery. o In the route to Tarma as we said earlier is the Club, the Hotel "Inca" the la Oroya Hydroelectric power plant, the Chulec sector with the hospital, and the Mayupampa high school. o Along the Horacio Zevallos Ave. are: TV, RR.PP., the Junin Hotel, and the Sierra and Industrial Relations Human Resources offices. o At the end of the Horacio Zevallos Ave. in front of La Oroya Antigua (at the other shore of the Mantaro river) is: Copper smelting plant, Lead smelting plant, Zinc refineries, the Training area, Security, Occupational Medicine, as well as the Operation General Offices. 2.4.1.2 Economical Activity with the surrounding Human Settlements Relationship o The economical function of the zone is characterized for being a catering intermediary between Lima and the coastal cities of: o Food products o Junin zone meat o Tarma and Valle del Mantaro zone vegetables, potatoes, and legumes. o Chanchamayo region fruits and coffee. o Industrial sopplies of cattle origin (wool). o Raw mineral material (specially copper, lead, zinc, and silver) for the National Market and external, coming from Centromin (Morococha, Casapalca, San Cristobal, Yauricocha, Cobriza, and Andaychagua). It is also a return point for catering of food (groceries) and final products such as dresses, furniture, etc. to the whole zone of La Sierra and Central Jungle. La Oroya City is surrounded by rich farming zones of Sierra Central characterized for its medium farming exploitation, oriented towards the production for the market as well as the Huancayo, Tarma, and Chanchamayo zones. In another direction (towards Lima) zones corresponding to the Puna region that cannot allow themselves agriculture nor intensive cattle production. Towards the Tarma zone, Huancayo and Junin we find a series of small villages (generally Estancias or villages corresponding to farming communities) located in the vicinity of the Central Road the ones that owe their existence principally to the ranching activities and farming at a small scale (self-consumption, selling what little is left) and the small services oriented to transport (restaurants, repair shops, etc.). Nevertheless, though they are close to la Oroya, their relationship is reduced to commerce of their products in the two weekly fairs in this city, for the majority of the final food products (groceries) proceed from Lima. (Picture 2.4.6) La Oroya performs an Industrial-Metallurgic of Smelting and Refineries function for the treatment of complex concentrates and the post-commercialization of the refined Cu, Pb, Zn, and by-products like Bi, Se, Te, In, Cd, and other chemical products and constitutes the main reason of its existence as an important urban zone of the Central Region of the country (between Cerro de Pasco and La Oroya are 40% of the urban population of the zone) which reverts when there is unemployment of miners for reasons previously discussed, for they return to their places of origin to dedicate to farming and ranching activities or transport and commerce, or go to Lima. Local artwork activities are practically non-existing, as we said earlier the percentage of the population dedicated to metallurgic activities and dependent families ascend to 34.08% of the city PEA, there is a 51.85% of the stable PEA divided between commerce and services of different sources among which are found employees of public and private institutions. All of which though directly or indirectly dependent of the company's activity constitute different areas. One fact that remarks this dependency is for example that the weekly fair and biweekly done in La Oroya and Santa Rosa de Sacco coincide with the paydays of Centromin Peru. What refers to the commercial sector it has been found 987 establishments between formal and informal of which 59.87% belong to food area (groceries, vegetables, etc.), 6.89% to clothing and footwear and in lesser quantity to household cleaning utilities and electrical gadgets. 74.82% of the commercial companies are family-type which involves more than one member of the family. In the services sector it has been registered 228 establishments of which 31.14% are formal restaurants and 8.33% are informal food sellers, and there are 29 mechanical and factories dedicated to transport services. The Industrial sector of the city of La Oroya is formed by 83 establishments of which 36.26% are distilleries of alcoholic beverages, followed in importance the textiles sector and bakeries with 15.63%, the fabrication of furniture with 21.65%. Also, there is an bottle and cal and plaster factories. 15.86% of the workers of Centromin perform complementary economic activities: 5.88% dedicate to commerce, 9.20% to services (masonry) , plumbing, mechanics) and 0.78% to other activities. 13.62% of the wives of the workers dedicate to other economic activities apart from their household duties (mainly to commerce 8.53%, and they do it in La Oroya). Given the importance that La Oroya City has acquired in the last years different government institutions, municipalities and privates and various ONG have come. There are 35 institutions between public and private ones. With respect to private companies of public services are: La Telefonica del Peru, postal services, local transport and radio services There are 4 cooperatives among which is "Cooperative of Save and Credit CENTROMIN Coop 299" Apart of this Oroya has eight popular dinner mess organizations of integrated Base by women of low economical resources , 18 mother clubs play a role in: Glass of Mil Program, PANFAR. 2.4.1.3 Hosing Conditions, The Infrastructure And Basic Services Of The UDP And Of The Populated Centers From Around 2.4.1.3.1 Work General Conditions On May 1996, the working population of the company in the UDP La Oroya was constituted by 248 members (Superior Administration), 209 (Professional), 611 employees and 2419 workers that when added to third made a total of 4536 workers. Though there workers in more or lesser measures according to their work specialty work in risky conditions: trauma, professional illnesses, the company attends to all the refers to health, households (free light and water), education for their children and recreational places, transport and scholarship systems. 2.4.1.3.2 Education and Health With respect to education, there are two education systems in La Oroya, one of which is the USE (Pulbic Units of Educational Services) which has on its power 11 Public high schools (3 of basic education, 6 of elementary, and 2 of higher education) of Centromin Peru S.A., the rest count on a good infrastructure, equipment and a roster of excellent quality integrated by the 296 workers. These units enjoy of academic prestige and has a total of 4448 students (on may 1996) which represents 33.71% of the scholar population. (Picture 2.4.7) The other 66.29% is formed by the 8744 students that study in the 45 Education centers, elementary, high school, Occupational Technical, and Superior of the public and private sector that constitutes the other sector of the educational system of La Oroya: The ADE (Educational Area of Development) which counts with 450 workers, there are also computer institutes, nursery, and Education. With relation to the Health area, the city of La Oroya, including Paccha and Santa Rosa de Sacco counts with three systems of health attention. o The IPSS (Social Security Peruvian Institute) which counts with a polyclinic oriented primarily to the senior citizens and with the Regional General Hospital which counts with 25 doctors in all specialties, 35 nurses, 72 beds, x-ray services, Analysis, and attends minor and major surgeries. It offers prevention services and assistance to insured and their dependents (in their majority CMP workers). o The Health Ministry which counts with three health centers of precarious infrastructure and equipment, the services it offers (consults, minor surgeries, Analysis, Birthing) are directed to the population that lacks Social Security, the health cases that require higher attention are directed to Tarma, Huancayo and Lima. o Finally, Centromin counts with the Chulec Hospital which has 14 doctors of different specialties, 13 nurses, 50 beds, and attends to major (a monthly average of 16) and minor surgeries, x-rays and analysis, Ecografias, Laborascopias, etc. It offers their services to family members of workers of the company that do not have attention rights in the IPSS, see Table 2.17. Among the illnesses most commonly attended in the different health centers of La Oroya figure in first place gastrointestinal, diarrhea, and infections with 50%, following respiratory and bronchial in which the cold and polluted climate influences, followed with a minor proportion of quisticas, endemic (hepatitis), parasitic, and rheumatic. Among labor-related illnesses, most frequent are traumas for work accidents, dermatitis, arsenical and saturnism (caused by lead contamination) which are frequently controlled, as well as Neumoconosis, and Silicosis not so frequent for being surface workers, see table 2.18. 2.4.1.3.3 Habitational Infrastructure The housing constitutes a fundamental social problem. Centromin La Oroya counts with a total of 3395 houses appointed to its workers of which 1064 (31%) are in adequate living conditions and 2331 (69%) are in inadequate conditions. In these houses live approximately 15376 persons with a median of 5 to 6 persons per family. These houses are located on the following sectors: o Behind the market, Calle Lima, Railway, Cantagallo, La Florida, Calle Lima, Alto Peru, 1 floor Plomo, 2 floor Plomo, Huaymanta, Buenos Aires "A", Esmeralda, Santa Rosa, Buenos Aires "B", Huampani, Marcavalle, Behind the Station. 83% of the workers live in houses appointed by the company (742 in special zones) of which the majority counts with two rooms. (Picture 2.4.8) The houses located in blocks and departments, have hygienic services, laundry rooms, and internal showers; on the other hand, in the sectors where the constructions where rooms have collective services: toilets, laundry rooms, wells, and showers. We observe that 38% of the workers, 9.74% have their own house in La Oroya; 27% have terrain's, 7.28% in La Oroya. (Picture 2.4.9) The average of the houses in la Oroya are 2 story and with 60m2 area of terrain with 50m2 of construction per floor, of noble materials in their majority, with cement floors, wooden windows and zinc and wood roofs. Also there are adobe houses especially in the particular part of La Oroya Antigua. All La Oroya has 11256 houses. The living conditions of these particular sectors: Club peruano, Behind the market, Av. Wilson, Alto Peru, Behind the Station, Railways y the Plomos, are or high degrees of decay and slum process ; and should be programmed for demolition. As we have seen, many houses have collective hygienic services, showers, laundry rooms, most of them kept in bad maintenance and hygiene. Water and electricity is freely provided by Centromin to its workers. The light has a rationalization program with restriction from 4:30 to 10 a.m. and 1:30 p.m. to 4 p.m. Water presents a problem of its own caused by pressure/fluidity accentuated by the deficient estate of the drainage system. The sewage, in the case of the inadequate houses and the case of La Oroya Antigua, can be seen that it is a canalization system of residual waters through open channels characterized by their constant obstructions that are nexus of accumulation of trash and rat nests. (Picture 2.4.10) Today the served waters do not receive any treatment and are discharged into the Mantaro and Yauli Rivers respectively, only 41.60% of the houses have adequate public services connected, 4682 houses have public network services connected, 2758 houses have a blind well, the populadores of 742 houses use as services the irrigating channels and 3074 houses use empty areas and mountain slopes for their basic needs. (Picture 2.4.11) o With respect to water catering the sources are: o Tishgo river: domestic use water, industrial and for EMSAPA (Municipal company of water services and drainage of la Oroya) o Cuchimachay: Industrial and for EMSAPA o Mantaro river: industrial water. o Marcavalle well: EMSAPA water. o Pichjapuquio spring: EMSAPA water. The amount of catered water for EMSAPA is subject to charge from August 1994 when the total control of the Marcavalle well and Pichjapuquio springs were transferred to EMSAPA on the same date Centromin started to cater domestic water for EMSAPA to distribute to these sectors: Calle Lima and Av. Horacio Zevallos, actually 5909 house possess connections to the public network, 4302 houses are catered by public pilones, 164 houses from well water, 54 acquire from cistern tanks, and 514 pick it up from channels or springs. The supply of light in La Oroya in the particular sector is given by Electro Centro; Centromin, with its interconnected network, it provides electricity for industrial use and for domestic use for the company workers. As we have seen for the treatment of industrial waste CENTROMIN has two crematory furnaces: One at the Smelter and the at Huaymanta. At the Huanachan zone in the Huancayo High way there is a Zinc Ferrites deposit. In the Mantaro river sector near Malpaso, there is an abandoned arsenic trioxide deposit and another near that same sector at the Hacienda Antahuaro zone. With respect to domestic solid residues (garbage) there is no sanitary treatment and trash is accumulated by the County and Centromin's Collecting trucks at the Cochabamba sector in the route towards Huancayo, 8 kilometers form LA OROYA 100 M from the high way. At the zones were the collecting trucks can not go, the county collects the trash on manual cart wheel and with shovels, but the population does not cooperate with the cleaning and throws the garbage into the streets, channels and the Mantaro and Yauli rivers (Picture 2,4,12) respectively. There are no containers to deposit the garbage. (Picture 2.4.13) Dumps have been created at the Mantaro river shore and in front of La Oroya Antigua. With respect to the deteriorated houses a demolition program, up to June 30 of 1996 results are that 303 houses have been demolished at the Club Peruano sector. At present, there are 14 houses in demolition process. At the Smelter zone almost all the houses have been demolished, and the demolition material has been conveniently disposed of. With respect to communication and recreation the people at La Oroya city posses TV channels and two broadcasting station. Some sectors as Tambo de Sol have a parabolic antennas. There are five radio stations two of which reach Junin. The Peruvian Phone Company is devising a expansion plant an improvement of there direct dial service. The Phone company has private communication central and fax that interconnects all dependencies and mining camps including Lima and Callao. In the city there are a total of 25 sporting centers most of which are in an average maintenance conditions, also there are 9 children playgrounds. La Oroya lacks green areas for passive recreations, them being as parks or plazas. The old golf club of La Oroya is the only open recreational area. o The company has 9 mess halls most of which are regularly attended. o Also the company by means of its social security promotes recreational programs for its workers and their families on holidays. On the other hand training courses are given to the workers in different levels and specialties : administration, security, environment, human relations, technical specialties ( metallurgic, mechanic, etc. ) The social service office offers courses for : Family Budget Planning, Preventive Health, Food Manipulation and Hygiene, Proper use of house holds and animal raising, Family Relation, Mother and Children Help, Health Test for Sicknesses campaigns, Organizations and Leadership) With respect to social projection in La Oroya The Public Relation Department maintains good and adequate relations with the different public and private institutions of the area. Also to motivate campaigns through the national police for the cleaning and other community actions. 2.5 Human Interest Environment 2.5.1 Archeological Resources The region does not count with own archeological resources and only works as an access way to the central zone of the country which is rich is such resources such as Tarma, Jauja and the Huancayo zones. 2.5.2 Protected National Areas There are not protected national areas an only works as an access way to the national park where the Stone Woods of Huayllay, Cerro de Pasco and the National Reserve of Junin around the Chinchaycocha Lake ( Lake Junin) are located. The lake is the second largest of the country in the Junin table land. Next to the zone are the Thermal Baths of Yauli. 2.5.3 Scientific and Tourist Sites The zone is an access way to the tourist circuit Costa Sierra Selva which goes from Lima to Tarma and the Chanchamayo valley. On the other side ther is the Mantaro valley Tourist route, with guided tours to the Ocopa Convent which dates back to the colonial times. Specialized tourism could be promoted for groups of people interested in knowing the industrial areas with guided tours. III PRODUCTIVE UNIT PROFILE (Mining and or Metallurgic Operation Descriptions) 3.1 Plan Design Characteristics This complex has three integrated circuits of copper, lead and zinc. In 1995 2 55 109 tons of concentrated copper, 191 575 tons of concentrated Lead and 154 710 tons of concentrated zinc were processed. These concentrates specially the copper one are polymetallic, with high concentrations of precious metals and impurities, they are subject to different pyro, hydro and electro metallurgic processes for the abstraction of refine metals having also a plant for the sub products recovery. Eleven metals are obtained ( Cu, Zn, Pb, Au, Ag, Bi, Se, Te, Cd, In, Sb) and nine chemical sub - products copper sulfate and zinc sulfate sulfuric acid, oleum, arsenic trioxide, zinc powder, sodium bisulfate, zinc oxide and zinc silver concentrate) . As it was seen in chapter I, part 1 point 7 these metallurgic complex had to suffer modifications and additions of new processes to achieve treatment levels mentioned above. 3.2 Industrial Capacity, Historical Production and Increase Projection. On table 3.1 it can be appreciated the installed capacity and the short range production increase potential through operation and short range investment optimization. Also on table 3.2 summarizes the refine metals production and sub products achieved form 1965 to 1995. 3.3 Raw Material Treated at the Smelter Circuits The following details the name, origin and concentrates mineralogical characteristic form the enterprise and the particulars (national and international) using by the smelter as row material for the operations. 3.3.1.

Copper Circuit (Figure 3.1.and 3.2) The smelter copper is initiated at the preparation plant, where the material is re circulating, the reagents and the concentrates form beds of copper. The mixture goes through a roasting process to eliminate the high quantity of arsenic As and sulfur S and some antimony Sb and Lead Pb. The solids of the process fumes are recovered by the electrostatic precipitators (Cotrell). At this plant arsenic trioxide is obtained As2O3 draining the arsenic from coming form the metallurgic process to the storage fields. The calcine product of the roasting, passes to be smelted at a reverber furnace ( with oxiful burners) were the metallic sulfurs at the calcine Fe S and Cu2 S, and the slag are separated. A matte is charged to the converters. The slag is discharged by a little hole located at the opposite from the horizontal burners and then it is granulated with pressure water to be stored at the Huanchan deposit. The water used reaches the 11 000 gpm that is discharged into the river. This situation will be eliminated when the water recirculating system is implemented. Once the matte is charged air is throw in to generate ferrous oxides which will react with the silica that is fed, producing the slag which will return to the reverber. Finally, part of the copper bars are rolled until converted in 5/16" or 9/16" diameter copper wire. 3.4.2 Lead Circuit (Fig. 3.3 and 3.4) Begins its process in the Preparation plant, where the re-circulating material, the meltings, and the concentrates are given in doses forming the lead beds. The bed is treated at the Lead Agglomeration Plant where amount of sulfur is reduced by means of a toasting process producing an agglomerated material with the proper physical characteristic properties to be treated in the vertical furnaces. The fine material originated by the process is recuperated in by filters and the central electrostatic smoke precipitator. The thick lead agglomerate is melted in the vertical furnaces using as a reducer and fuel coke, in the load a percentage of iron debris is conditioned with the function to form magnetite and avoid loss of metals (Pb, Ag) in the waste. By separating the waste from the work lead, this waste is then granulated at pressured water and then stored at the waste deposit of Huanchan. The water is then poured towards the Mantaro river. The lead, produced in the vertical furnaces denominated work lead, is transported to receptive pans where it is skimmed. The skims are then loaded in one reverberating furnace where the copper matte, the speiss (Cu-As, Sb), and the bullon lead are separated. The bullon lead returns to the receptive olla mixing with the clean work lead. This mixture is decopperized to eliminate impurities (Cu, As, and Sb). The bullon lead produced at the smelter, with an Antimony (Sb), Bismuth (Bi), and Silver (Ag), is electrolytic refined by a modified Betts process. The corroded anodes are left with insoluble impurities adhered to its walls, and with occluded electrolyte between them thus it is necessary to clean them for immersion to recover the electrolyte; then, the mud is gotten rid by pressurized water (35 000 l/d). The pulp is sent to the "Larox" automatic filter, obtaining an anodic mud with approximately 27% humidity, ready for the posterior treatment 3.4.3. Zinc Circuit (Drawing 3.5) The zinc concentrates coming form the Paragsha and Mar Tunel are treated in two roasters, one of fliud bed (FBR) and other one of turbulent bed (TLR). Part of the zinc concentrates is mixed with zinc oxide dust that was recovered at the central electrostatic precipitator to be buck shot with sulfuric acid. The concentrates are after these treated at the 3 roasters of fluid bed, obtaining calcinated pellets, which are sent to the crushing and sifting unit. This product is stored at the leaching unit tanks. The turbulent bed at the roaster produces calcine that is also transported to the storage tanks at the leaching unit. With the SO(2) obtained at the roaster's turbulent bed a commercial grade sulfuric acid is produced (45 000 tons average) The zinc oxide recovered at the cyclones and electrostatic precipitators are also stored at the leaching unit tanks. The principal objective of the leaching stage is to dissolve the zinc oxide and the zinc sulfate that are present at the calcine The leaching process is undertaken in shaking tanks where the loads of spent electrolyte, fine calcine and concentrated sulfuric acid ( this last one only when the process requires it) are loaded. The iron oxides with manganese dioxide and precipitates along with the arsenic, antimony , etc. the zinc ferrites remains insoluble. The pulp obtained is separated in fine particles (passing to the solids separation unit) and heavy particles (sandy) that will be re-treated in a new leaching process. At the solid separation plant the impure solution is separated (overflow) from the residue (underflow); this last is washed and filtered to assure maximum zinc sulfate extraction. The residue (zinc ferrites) is sent to the floatation plant, where zinc and silver are recovered in the form of concentrates. Part of the remaining tail (zinc ferrites) is treated at the zinc residues leaching plant (Zileret) and the other part is sent in a pulp form to the Huanchan deposit where it is stored for its subsequent treatment. The impure zinc sulfate solution is derived to the purification unit where copper, cadmium, small amounts of arsenic and antimony are precipitated using zinc dust. This solution is filtered and the residues are sent to the Cadmium Plant for treatment. The pure solution is sent to the zinc leaching unit. The zinc sulfate solution electrolysis occurs between the aluminum cathodes and the silver and lead anodes. After the 16 hours deposition stage, the cathodes are taken out from the zinc cells. The zinc is de laminated and sent to be smelted at the induction furnace. Zinc is cast in 24 kg. bars for its commercialization. 3.4.4. Associated Processes 3.4.4.1. Sulfuric Acid Plant The process is composed of three main stages: a) SO(2) Gas Purification The gasses coming out from the zinc circuit turbulent bed at the roaster enters to a dry electrostatic precipitator to eliminate the remaining dust. Then it goes to a washing tower where it cools down. The discharge water from the SO(2) saturated tower goes to a gas purifier where an air current extracts most part of the SO(2) gas. The gas recovered is fed again to the tower. The resulting gas passes by a fog precipitator. After purification, it passes through a drying tower against the current. At this point most of the water vapor is extracted from the gas. b) SO(2) to SO(3) Conversion The converter contains multiple catalyser coats to accelerate the reaction between the SO2 and the oxygen to form the SO3. When leaving the converter , the gas passes through the cooler exchanger, which cools down the SO(3) gas before passing to the absorption system. c) Gas S0(3) Absorption The already cool SO(3) gas is not combined directly with the water, but by 98.5% to 98.8% H(2)SO(4) dissolution in this conditions, the SO(3) is united with the acid water at the absorption tower. 3.4.4.2. Coke Plant This plant has two independent batteries that operate parallel to each of the coke furnaces, using its own coke gas for the combustion and the furnace warming. The coal is discharged at the mill hoppers towards the hammer mill to be elevated by the buckets to the feeding chute, creating a uniform grain size. At that moment, the material is loaded in each of the horizontal coke furnaces. During the discharge, after the coke cycle, the coke that is produced is transferred to each furnace by a tuyere to a chain haulage that takes it to the "coke shaft" and finally it is cooled down by a water stream. The heated gases that come out of the furnace cool down by water sprinkles condensing the coal tar, which is taken to the settling tank. The coal tar free of water is sent to the copper reverber to be used as fuel and the coke is sent to the lead circuit. 3.4.4.3. Oxygen Plant This process consists in breaking up the liquid air in its components, taking advantage of the different boiling temperatures. To undertake this process the air fractionating plant has the following partial processes: a) Air Compression b) Humidity and a Carbon Air Dioxide Evaporation. c) Air Cooling to the melting temperature. d) Cold Production e) Air Liquefaction f) Air Fractionating (rectification) g) Dangerous Impurities Separation 3.4.4.4. Fluosilicic Acid Plant The first stage of the reaction is done at a rotating cylindrical furnace. This furnace receives slowly the Calcium Fluoride in form of dust and the sulfuric acid. The temperature control is important since the reaction at the beginning is very violent. The Fluorhydric gaseous acid formed at the furnace is conducted to two condensers that are cooled externally with water. The gas is absorbed by the water that moves against the current towards the gas direction. The gas that could not be absorbed by the water at the first condenser goes to the second condenser through a lead tube. The fluorhydric acid obtained at the condensers is sent to a mixing tank where it reacts with silica finally grained maintaining the mixture in constant movement along with air, producing in this way the acid solution that will be decanted. 3.5 Operations and Emissions Control At La Oroya Metallurgical Complex there is a Process Control department that is in charge of the following duties : o Gas Analysis Tests at the: Concrete Stack, Lead skimming Reverber, Copper Reverber, Kiln Furnace at the Zileret Plant, Coke Furnace. o Temperature Control, Dust Volume and Losses at different Smelter ducts: Converters, Agglomeration, Copper Reverber, skim, zinc roasters, and copper roasters heated Cottrell efficiency - Sulfuric Acid Plant, Arsenic Cottrell efficiency and anodes, ventilation system reverber losses, anodes, concrete stack, copper reverber stack. o Dust Automatic sampling operations and control at the copper reverber smelter ducts, converters, agglomeration, concrete stack, and copper roasters. o Measurements of the tiraje, copper reverber system temperature and arsenic furnaces. o Coke Furnace gas volume measurements. o Smelter and Refinery monthly inventory of heavy oil and diesel. o Rain measurements at the La Oroya and Mayupampa meteorological stations. o Barometric Pressure measurements, environment temperature and relative humidity at La Oroya. o Flow Measurements and Sampling of liquid elements at monitoring 49 points. o Control and data taking of the gas analyzers equipment and data taking of the grained material at the following sampling points: o Huanchan: SO(2) percentage, wind direction and speed as well as grain material of high volume. o Workers Union: SO(2) and grained material of low and high volume. o Casaracra: SO(2) percentage and grained material of high volume. o Inca Hotel: SO(2) percentage and grained material of low and high volume. o Cushuropampa Sub Station: SO(2) percentage, wind direction and speed and grained material of volume. 3.6 Activities and Support Installations 3.6.1.

Basically, because the electrolytic process at the copper, lead and zinc refineries. 3.6.3. Analytical Laboratory The chemical analysis are executed by the La Oroya Analytical Laboratory, counting with modern instrumental analysis techniques and classic methods. The instrumentation laboratory is well equipped with X ray machines, atomic absorption espectrophotometry , espectroscopy of optical emission, espectrometry of X rays, UV- VIS, Colorimetry and espectrography of emission. Actually, it is working a atomic absorption espectrophotometer 20 BQ PLUS with graffito furnace GTA -96 and a hydrure generator VGS -76 that are used for the analysis of environment samples. Centromin's Analytic Laboratory was registered as a participant of the Analytical Training Program of the Monitoring Program established by D.S.No.016-93-EM and its Modification Rule D.S. No. 059- 93-EM. Centromin has also registered to complete the Laboratory diagnosis of performance involving the Monitoring Program of Water Quality, Air and Emissions corresponding to the 01 Study of "Fulfillment Evaluation" required by the General Office of Environmental Issues at The Mining Ministry. 3.6.4. Workshops It includes the following services: o Storehouse, Structural Shop, Garage, Instrumental Shops, Mechanical Shops, Electrical Shops, Security Shops and Electronic Divisions. 3.6.5 Supply and Swage Water Distribuition La Oroya location has sewage service. The service discharges sewage with no treatment to the Mantaro River and to the Yauli river. The volume of sewage water coming from Centromin's residential areas and the different production and services is estimated in 227 liter per second. The waste and garbage are collected daily by trucks and transported to the Cochabamba zone at 8 kilometers from La Oroya . They do not receive any treatment, they are poured in Yauli and Mantaro rivers. 3.6.6. Smelter Swage Water Treatment and Disposition At this time a pilot septic tank has been built at the smelter and to study and manage the waters coming form the hygiene services at the Storehouse, Structural Shop, Intrumental Shop, Garage, etc. 3.6.7. Control and Dust Recovery The smelter operation has three units for recovering the dust coming form the gasses at the Copper Circuits, Lead Circuits, Zinc Roasters and Anode Residues through the precipitators system. o Central Cottrell Precipitators System o Precipitators Arsenic Cottrell Sytem o Anode Residues System 3.6.8. Environment Monitoring Stations Installation and Location To execute the Monitoring Program Centromin has the support of a Testing Control Section for water monitoring and air quality control and with the Ventilation Section for measuring the noise levels at the smelter surrounding areas. o Water: There are 8 water Monitoring points (Y1, Y2, Y3, M1, M2, M3, M4, M5) which can be observed in Table 2.2. The exact location of this points is described in number 2,1,3. o Air : For the air quality 5 continuos monitoring points have been installed (Inca Hotel, Cushuropampa, Workers Union, Huanchan, Casaracra) in a ratio of 2, 4, 6, 8, 10 Kilometers from the Main Stack. As it can be observed in table 2.12. The exact location of this points are descirbed in number 2,4,2. o Noise: There are 31 monitoring points that measure the level of noise. It has the objective of determining the possible influence of the Metallurgical Operations and Services. The measurements are accomplished between 4:00 am and 6:00 pm. As it can be observed in Table 3.6 from 4:00 am to 7:00 am when there is very slow traffic the noise level varies between 50 and 60 decibels. In normal conditions between 10:00 am and 5:30 pm the higher levels reached 72,5 decibels due to vehicles transit and trains. 3.6.9. Management of Solutions The monitoring that is being developed takes samples and registers flows 2 times a week. Additionally, when a new and extraordinary event takes place additional sampling is taken. IV ENVIRONMENTAL IMPACT EVALUATION AND ANALYSIS SUMMARY 4.1 Evaluation The environmental impact evaluation reported in this document named PAMA has been executed taking as base : The EVAP reports that consideres data from 1994 , also takes into consideration the "Monitoring, of the emissions and discharges declaration" that holds information from the year 1995. In addition to "The environment emission and discharge auditing" done up to June 1996 and "The environment components and metallurgical activity" described in Chapters II and III as well as other analogue documents. 4.2 Impacts Sources From the analysis of the data contained in The EVAP and the present document. Three impact sources have being identified: 1. Gasses and Dust 2. Liquid Effluents 3. Solid Residues. 4.2.1 Gasses and Dust o Origin The gas emissions are originated as a consequence of smelting concentrates that contain high contents of sulfur . They are discharged into the environment in three ways: Main Stack, Secondary Stack and Fugitive emissions. The dust is generated by mechanic hauling to the furnaces, handling of crude concentrates, wind action, as well as by contaminant loads of SO(2) and other gasses. According to the 1995 analysis, the principal gas emission contaminant is SO(2)( (91.6% of this gas is evacuated through the main stack and the 8.4% is used for the H(2)SO(4)). The discharge by the Main Stack is 899.8 Tons per day with a test result of 15 380, 18 mg/m3. N, 59 154 times higher than the Permissible Limits for industrialized zones. Other contaminants of medium importance are CO(2) and CO with 46.7 and 0.74 t/d respectively. In reference to dust and suspension particles there have been quantified only the ones emitted by the main stack which gives a load of 8.9 t/day. 4.2.1.1 Physical Impact on the Environment o Water The surface water is directly affected by the gasses, damaging its quality. The underground water is affected by filtration coming from the surface water. o Weather This component is affected by the gasses when the "green house effect" is produced, creating micro climates that do not belong to the region. o Soil The soils are affected by the rain, that by washing the environment air generates acid precipitation contaminating large portions of soil. 4.2.1.2. Biological Impact The natural landscapes show us that the atmosphere has received and is still receiving high quantities of gasses and particles that finally precipitate in form of acid that constitutes the cause of the ecosystem destruction. The native Flora and Fauna has diminished damaging the cattle raising. The dust produced by the mechanical haulage at the furnaces and the crude concentrates handling contribute to contamination and its effects over the ecosystem. 4.2.1.3 Social Environment Impact The toxic fumes affect the population, especially the ones that are near to the Unit, causing respiratory and allergy problems. The water and soil are contaminated and can not be used either for domestic activities or agriculture. 4.2.2. Liquid Effluents All the liquid effluents are generated by the process conditions and industrial operations that the complex carries on. From the information reviewed it is concluded that the effluents that have 90% of the contaminant load are: o R -1 Copper Refinery Effluent (Ex-Lead) o 118 Effluent - Slag Sinter o 119 Effluent - Main Channel No. 2 o 126 Zinc Electrolytic Plant o 135 Main Channel No. 1 o 136 Parallel Channel to the Main Channel No.1 o 137 Zinc Ferrites Tank Contaminant Load The following table shows contents that are over the Maximum Permissible Limits MPL of the above stated effluents. Calculus Sources are the Table Data 2.3 and the EVAP. 4.2.2.1. Impact over the physical environment As Table 4.1 shows the liquids poured directly to the Yauli and Mantaro Rivers have a high content of contaminants, affecting the water quality. Furthermore, these waters filter, contaminating the underground water. 4.2.2.2. Impact over the Biological Setting. Having contaminants that are over the MPL, the Mantaro river habitat conditions are altered. The water muddiness precludes the light from penetrating limiting the photosynthetic activity and reducing the dissolved oxygen quantity. Consequently, the primary productivity also modifies the water temperature. The NO(3) excess could produce water eutrophication and reduces oxygen. 4.2.2.3 Social Economic Impact The superficial waters that have been contaminated by the unit's effluents have affected the agronomy development of the area. This has decrease the areas population survival means and economy. Furthermore the sewage waters constituting an infections focus, when transported throughout open channels all through the city to the rivers highly contributes to contamination. 4.2.3. Solid Residues Origin The solid residues are generated at the Smelter and Refinery operations and processes as a consequence of the treatment of diverse concentrates in solid forms (Slag, Trioxide, As, etc.) and Pulp (Ferrites) deposited at land near by the industrial zone. Some volumes of small magnitude are poured into the river (Calcium Sulphate) Contaminant Load The large volume of zinc leaching slag and residues generated by the industry (See Table 2.5) cover a good area of land. Moreover, the arsenic trioxide fields being openly exposed constitute some potential sources of dangerous contamination. Despite the light solubility of this material the high toxicity of the product is considered lethal. 4.2.3.1 Physical Impact The geomorphology is affected by the embossement modification. Even though the solid residues are of low solubility they are not exempt from containing contaminants agents, which are transferred to surface waters and then to underground water. Due to Eolic action the fine particles coming form the residues are taken to the surrounding areas damaging the soil quality. The relative stability of the deposits is considered potentially dangerous in case of contingencies such as seismic occurrences and huge pluvial precipitation. 4.2.3.2 Impact over the Biological Environment The solid residues at Huanchan, Malpaso and Vado (Arsenic Trioxide, slags and zinc ferrites) are a physical type of contamination that have altered the terrestrial and aquatic ecosystem, stopping flora growing and affecting the fauna. Moreover, they contaminate the Mantaro River. 4.2.3.3 Impact over the Social and Economic Environment The residues are dangerous sources of contamination for the population that live in the surroundings areas, specially near the arsenic trioxide fields. In relation to the urban solids, which are located at the Yauli and Mantaro ravines due to the County and Centromins lack of pick up services, they have been constituting infectious centers that are worsen by the presence of pigs and other animals. 4.2.3.3. Complying with the Safety and Industrial Hygiene Rules. It has been noticed that some of the Safety and Hygiene Rules D.S. 023-90 EM are not being complied with. The rules that are not being complied with are: o The workers use of safety equipment ( breathing masks). o Opportune discharge of iron scrap and industrial waste. o Animal raising at the mining towns. V MITIGATION MEASURES PLAN 5.1 Introduction This seciton presents Centromin mitigation measures, that will be implemented by diverse projects to eliminate or diminish the already caused impacts. The environment control and the mitigation measures were implemented by the metallurgical complex from 1922. In accordance with the demands that existed at that time, some improvements were made during time, but in many cases have not reached the levels required today. The metallurgical activity has affected the quality of the physical, biological, social-economic and environment resources. The aim is to correct this actions with the control measurements and mitigation actions presented in this chapter. Some of the measures are implemented already and others are executed in established terms by PAMA with the objective of diminishing or eliminating the following impacts: o The air quality o The water quality o The soil quality o The erosion and soil sedimentation o The biological resources o The social - economic resources. The specific methods used to diminish each one of the detailed impacts are described in the following paragraphs. Due to the dynamic character of the environmental problematic, CENTROMIN PERU SA will continue to review the actual mitigation measures or implementing new ways if it is necessary. In Table No. 5.1 a Investment Program chronogram for PAMA is shown : 5.2. Gas Emissions Control 5.2.1 Gaseous Emissions In general it is necessary to point out that the variety of contaminants originated at the distinct operations and processes are emitted to the atmosphere by three well defined means. a) The main stack (167,5 meters of height) constituting the most important emitter. b) The secondary stacks in a number of 95 units of different dimensions (from 4 to 12 meters) and distributed at the different plant circuits. c) Defined sources in accordance with the DGMA of the Mining Ministry Terminology so called "Fugitive Emissions. The main stack as it was pointed out before is the most important "gaseous emissions" emitter. Gas emissions are mixture of gases, vapors, combustion fumes, metallic fumes and grained material or dust that due to their components dimension are not pulled by gravity and are being incorporated into the environment. Among the secondary stacks, it has been studied the contribution of the Iron Stack (91 meters height) as well as the coke plant, and some others that we will mention above. The emissions through these stacks need to be defined with much more detail, however it has been observed that the majority of them are not extremely harmful because they are combustion gases, water vapors and inert dust. In relation to the fugitive emissions these escape directly to the environment. Its origin is diverse. They are produced in a higher or lower grade by lack of control at the processes, lack or problems at the ventilation systems, micro-meteorological changes ( wind gusts, temperatures and humidity). It is very difficult to quantify because of its irregularity and fast dispersion.

Gasses The gasses that are emitted through this main stack come from the electrostatic precipitators (Central Cotterell), the arsenic recovery and the anode residual plant (Cottrell PRA). It is characterized by a huge flow (34518 Nm3 / minute, average) and its contents of SO(2) (899.8 metric tons daily). The SO(2) tributaries in percentage are the following plants: Copper Roaster 4.10% Copper Reverber 18.31% Copper Converter 24.37% Lead Sintering 21.83% Lead Furnace 4.35% Zinc Roasters (FBR) 19.32% Anode Residues 7.72% The 7.3% total sulfur that enters is transformed in H(2)O(4) and the 10.9% is set at the slag, copper sulfate, etc. and the remaining 80.8% is poured into the atmosphere as Sulfurous Anhydride. 5.2.2.2 Grained Material The grained material reaches an approximate total of 8.896 metric tons per day and from them it is being determined a contribution of principal heavy elements. They are as follows: Lead 1.79 t/d Arsenic 1.37 t/d Zinc 0.33 t/d Antimony 0.24 t/d Cadmium 0.07 t/d 5.2.3. Iron Stack Emissions These emissions reach no more than 9% of the flow emitted by the main stack. The solid content constitutes 3% of the same flow. However, they are very much significant due to their quality and concentrations of Copper, Iron, Lead and Arsenic. 5.2.5. Other Emissions Sources It is worth mentioning among other emissions sources, characterized during the EVAP the following: o The coking chamber gasses are evacuated with no treatment. o The ventilation system of the Bismuth Vessels numbers 4, 5 and 6 at the Residues Anode Plant. The system dismisses the remaining gasses after the fumes are captured by the exhaust hoods and the grained materials is retained by gas washer. o The Three Stacks located at the Plant of Anode Residues that route the fumes generated during the Antimony and Bismuth selective oxidation of the Converters 1,2,3 and 4 and the Bismuth Reduction at the reducing reverber. Grain material has previously recovered in three filter bags. o The ventilation system of copelas at the Anode Residual Plant that allows to capture metallic fumes of the copelas 1, 2 and 3 which are recovered at the gas washing and at the electrostatic precipitators ( humid one). The remaining gasses are evacuated through the stack. o A group of 9 multiple stacks belonging to the fluid bed (FBR) of the Zinc Roasters Plant - pellets unit, ventilate a number of equipment such as: The pellet reception bin of the reactors No. 1,2, and 3. The zinc dust reception system. (recovered at the 1,2,3 units and the central electrostatic precipitator). The vapors and gasses generated at the mixers 6P1 and 6P2, the crude pellet dryers 8P1 and 8P2. The humid pellet dryers. Washers 1 and 2. Mechanical Transportation System of crude and dry pellets (which grain material is recovered in a bag filter 2PDB) , and the calcine transportation (bands, coolers and readlers 7B1 and 7B2, band 8B) To complete the origin of the global emissions the following is an analysis of each principal circuit emissions, 5.2.6 Copper and Lead Refineries Emissions This production unit has two defined circuits, but for this report they have been grouped because some of the installations are shared or interconnected, specially in relation to the effluents course. The circuits are composed of the Copper and Lead Refineries diagrams of the flows and emissions are shown at the process description graphics. Atmospheric Emissions The electrolytic refining process used by this unit requires many operations with temperature changes, in such manner that the main gaseous emissions are water vapors containing higher or lower grades of specific contaminants. The leaching and anode slime washing and Copper and Lead cementation generate water vapor loaded with sulfates and acids (H(2)SO(4), HF, H(2)SiF(6), Cu - SO(4)) haulage in a mist manner of mechanically. At the refrigeration operations in general (the copper bars, copper wire, etc) huge volumes of water vapors with very little or no strange materials are produced. During Lead Fusion metallic vapors break off to the environment, normally of a short diffusion distance, due to precipitation after the particles cooling. Certainly, there are combustion gasses which are evacuated in an independent manner from the process gasses. In general there are not treatment systems for the gaseous emissions, Additionally, there is no flow and detailed components information. At the interior work environment it is easy to perceive electrolytic refining characteristic odors probably due to the lack of efficiency of the ventilation vent. To have a less qualitative idea of each refinery contaminant contribution Tables 5.3 and 5.4 show processes and characterized operations, including control systems that are connected in 19 ventilation stacks.

Monitoring Stations The monitoring stations have been located taking into consideration meteorological and orographic factors, electric energy facilities, access, surveillance and location based on the Yauli and Mantaro basins proximity.

The evaluation results are accomplished at the stations previously described, shown in Tables 14, 15, 16 and 17. In the diagrams, the S0(2) concentration variations are shown as well as the grained material with respect to time hours. 5.2.9. Atmospheric Contamination Problems and environmental effects The Centromin environmental problem management has an extensive and aged data, studies have been executed with some continuity at different stages of its long existence ( before and after the company belonged to the Peruvian State). However, it must be recognized that the Ministry of Energy legal rules regarding environmental issues have had the virtue that this problem is now assumed in a systematic way having very clear objectives. CENTROMIN Office of Environmental Issues to comply with the EVAP document has accomplished an number of actions such as gathering and unification of the existent data, operation of the monitoring stations and atmospheric emissions measurements; including all the intermediate programs that were necessary for these objectives. In this way and following the parameters that were established by the respective protocols, the activities and actions have been divided in two big work areas. One at La Oroya the metallurgic complex installations ( Smelter and Refinery) and the other one at the external environment at the surrounding the city atmosphere embracing a 10 kilometer ratio. In the first case, the objective still is the IDENTIFICATION and PREPARATION OF AN INVENTORY of the contamination sources and the second one is a Systematic Monitoring of the environment air quality as well as the meteorological aspects. In relation to the effects, the verifications deriving from the identification and sources inventory activities show that the emissions discharged through the stacks especially by the principal stack, are the actual virtual and potential cause of air changes. The contrary occurs with the so called "fugitive emissions" which have a higher influence at the work environment, they could have an effect in the liquid effluents quality and soils due to the sedimentation phenomena. 5.2.10 Solutions that have been considered to Mitigate the Gas and Dust Effects The number of activities developed relating to how the atmospheric contaminants are generated and the air quality allows one to conclude that the long term solutions must be linked to the operations and processes, machinery and equipment as well as to the human attitude at the different production stages. "The solutions are at the plant" is the phrase that summarizes the most important approaches concerning the environmental policies at the company. It is well known the English principle that affirms that the contamination must be controlled through "the best practical resources available". The above coincides with what it seems the most convenient thing to do. At the smelter some operations and plants are utilizing environmental care actions achieve miner - metallurgical process efficiency. This is the case of the air fractionating plant that provides pure oxygen to the copper reverber circuit. Instead of using air, an active and clean fraction (O(2)) is used, as a consequence of this a lesser volume of gasses with fewer particles contents and gaseous contaminants is handled. The metallurgical index changes at the copper beds have permitted a lower demand of pyrite (60 000 tons/a) and fluxes (100 000 /a). Moreover the operations have improved. Thus, a higher capacity is available at the copper roaster plants, reverber and converters. In this way 50 000 tons/a of SO(2), 80 000 t/a of slag and 1 400 t/a of dust are not longer being generated. There is lower demand for material transportation (railroad, transportation bands, etc.), energy (oil). Among the advantages achieved the following are found: The reduced generation of solid residue, liquids and gasses and the work environment improvement. The implementation of a new agglomeration plant has allowed the use of only one automatic reactor instead of eleven, one gas generation point, one compact system for the recovery of dust (by bag filters) and a better quality product has been achieved. Among the environmental advantages achieved it is noted the lesser production of fugitive gasses and its consequential work environment improvement (compact equipment) The continuation of this type of improvements, including the double objective of improving performance and contaminant control will allow the steady management of the present persistent problems. Today it is becoming a reality the correlation of productive processes with its contamination characteristics, since that knowledge sets the foundation for practical and effective solutions. 5.2.11. Projects to Implement Centromin has projected to implement two sulfuric acid plants: - Cu - Zn Sulfuric Acid Plant Location : Actual Sulfuric Acid Plant Adjacent area Investment : US $ 40 000 (the amount covered by the Copper Smelter reaches US $ 13 700 and by the Zinc Refinery US $ 26 300) Study : The study will be administered by the Metallurgical Process Control Division, the Copper Smelter and the CENTROMIN PERU S A Zinc Refinery. Description : Consists in installing a module for the sulfuric acid production with a 205 000 t/a capacity. This module will process 45 693 t of sulfur (135 k t of acid) coming form the zinc circuit and 23 693 of sulfur (70 kt of acid) coming form the copper circuit. This plant must operate with 95% minimal efficiency. Must set as a minimum 83% of SO(2) generated in both circuits and must comply with the Ministry of Mining and Energy rules stated in Ministerial Resolution No. 135-96 EM / VMM. - Cu - Pb Sulphuric Acid Plant Location : Old agglomeration plant area Investment : US$ 50 000 (the amount covered by the Copper smelter is US$ 27 500 and by the Lead smelter is US$ 22 500). Study : The study will be managed by the Metallurgical Process Control division, the Copper Smelter and the Lead Smelter of Centromin Peru S.A. Description : It consists of the installation of one module for Sulphuric Acid production with a capacity of 300 000 t/y. This module will process 45 693 t of sulphur (195 kt acid) coming from the modified converter. The flux diagram shows the gas management and distribution at the Sulfuric Acid two modules. Naturally, that this needed operations modernization implementing advanced technology this include: For the Copper Circuit: The implementation of a casting wheel, a converter of a higher capacity (13' multiplied by 30'), a roaster for dirty concentrates, a dryer for clean concentrates, a converter type "El Teniente" replacing the actual cathodes by Titanium (Copper Refinery), oxygen use at the anode residues, etc. For The Lead Circuit: Replacement of the present sulfuric acid pre - heater, changing the turbulent bed chamber (TLR), a new Purification Plant and a effluents treatment plant, replacement of the three fluid beds for a turbulent bed, etc. 5.3 Control over the impact on Water Quality 5.3.1 Smelter and Refinery Liquid Effluents Treatment Control La Oroya metallurgical complex has two principal areas were the installations are located for the smelter and refining. For the smelter there are three main circuits: - The Copper Circuit - The Lead Circuit - The Zinc Circuit For the Refining there are: - The Copper Refinery - The Lead Refinery The effects of the environmental improvements that CENTROMIN LA OROYA has been accomplishing starting from the EVAP conclusion are reflected on the receptor bodies contamination mitigation (Yauli and Mantaro River). The following is the brief description of the different effluents that existed in EVAP the work that has been implemented or are being implemented to reduce the contamination and at last some special projects that will need to be implemented to complete the purification of all effluents. The present chapter goes along with an Annex that shows a summary of the Investment Cost Table of the works that are done or will be done. Copper Circuit a) General Description of the Process The copper smelter process starts at the preparation plant where the re circulating, fluxes and concentrates material are distributed forming the copper beds. This mixture is put through a roasting process to eliminate the bigger quantity of arsenic (As), sulfur (S) some antimony (Sb) and Lead (Pb). The process solid fumes are recovered by electrostatic precipitators (Cottrell). In this plant Arsenic Trioxide is obtained (As2 O3) extracting the arsenic from the metallurgical process. The calcine, product of the process of roasting goes to be smelted in a reverber furnace ( with burners oxi-fuel) where the metallic sulfurs are separated (FeS and Cu2S) from the slag and an adequate matte is produced to be loaded at the converters. The slag is discharged through a hole located at wall opposite from the furnace. It is then granulated with pressure water, afterwards it is stored in the Huanchan slag deposit. Subsequently, the matte is loaded into the converters where air is injected to generate the ferrous oxides, the same that react with the silica producing slag. The slag returns to the reverber. In a second stage the copper sulfur is oxidized by air, which reacts with the same sulfur producing blister copper. This copper is transferred to the retention furnace to be cast as anode. The fumes solid contents at the fusion and conversion stages are recovered by the electrostatic precipitators. The SO2 gases are evacuated to the atmosphere by the main stack. b) Effluents Management. o The Gold and Silver Refinery Plant partition solution. Tributary of the Main Channel No 2 Code 119 The gold and silver partition solution is done using H(2)SO(4). As a process effluent there is a solution that after a zinc cementation is collected in cylinders and sent to the cadmium plant leaching tank 1. This operations is done once a week. The following profile has been done to eliminate this effluent. PROJECT: Management and Disposal of the Solution coming from the Silver Refinery Antecedents: The high acidity solution resulting from the zinc cementation as an effluent that comes form the gold and silver partition was being evacuated in the river. But because of its high content of zinc today it is being sent to the cadmium leaching plant. Studies: Today the solution is being collected in cylinders. The cylinders are sent to the cadmium plant where they are treated with no problems. Objective: Stop the high acidity (350 g/l of H(2)SO(4)) solution discharge into the river. Project Description: A pipe transportation mechanical system will be installed. The solution will be pumped in such manner that will preclude leaking and accident risks that its high acidity could cause. Project Duration: It is estimated that the implementation period will be 6months. Costs: The cost of this project execution is estimated in $ 5 000. 00 and it will be accomplished with the complex own money. o Residue Anode Effluent Plant - Code 123 This effluent collects the waters coming from the Selenium Precipitator, Selenium Unit Overflows, Cooling Gasses Reverber and the Bismuth oxide chloride gas washer.

After this the solution is neutralized with lime until the pH is neutral to recover the copper. Finally, The solution is treated with NaCI to precipitate the remaining plant and the final solution is sent to the main channel number 2 (after it is settled). Implementation Tasks The settling tank enlargement to recover silver in the form of silver chloride. Lead Circuit a) Process General Description Starts its process at the preparation plant where the re - circulating material, fluxes and concentrates are distributed, forming a Lead bed. The bed is treated at the sintering plant where the amount of sulfur contained is reduced through a roaster process, producing a sintered material with appropriate physical characteristics to be treated at the Lead Vertical Furnaces. The grained material originated at the process is recovered in bag filters and the fumes at the central electrostatic precipitator. The heavy lead agglomerated is smelted at the Lead Vertical Furnaces adding a percentage of iron scrap with the objective of preventing magnetite formation and precluding metal lost (Pb and Ag) at the slag. When separating lead matte this is grained with pressure water to be stored at the Huanchan Slag Deposit. The Lead produced at the Vertical Furnaces named Lead Matte is transported to the receptor pans where it is skimmed. The skims are loaded in a reverber furnace where the matte is separated from the copper. The speiss (Cu-As, Sb) and the lead bullon. The Lead bullon returns to the receptor pan mixing with the clean Lead Matt. This mixture is de-copperized to eliminate impurities (Cu, As and Sb). The Lead after being de-copperized is heated up and pumped to the casting section pans. They are maintained at 350 to 380 (Degree)C of temperature. This is performed to accomplish the anode casting at the horizontal wheel. b) Effluents Management o Furnace Reverber water and Speiss Granulation. Tributary Code 118. PROJECT: Refrigerating Water of the Reverber Furnace and Speiss Granulation. Management and Disposal. Antecedents: Approximately, 630 liters/min if Tishgo (river) waters are used to cool the Furnace Reverber jackets that finally will be discharged into the Mantaro river. This operation is continuous. Furthermore, the Mantaro River waters are used for the speiss granulation in an approximate flow of 1500 liters per minute. They are discharged after the operation into the Mantaro River. This operation is intermittent. Studies: The studies have been done by the Engineering department and are supported by Ecolab SRL consulting firm. Objective: Preclude discharges into the Mantaro River. Project Description: The waters of each line will be re-circulated. In the reverber furnace case a reception tank will be installed with a re-circulating pump directed toward the furnace. The SPEISS granulation case (which is not continuous) will be executed after a retention of solid particles treatment is performed. The need for a storage tank of 135 m3 with a pump and re-circulating lines has been calculated. Project Duration: A period of a year has been estimated for its installation. Cost: The estimated cost to execute this project is 50 000 .00 and it will be with the company's own resources. o Main Channel Mud in front of the Agglomeration Plant. Code No. 135 The water washing bands take the dust that is deposited in this area. This occurs when the water falls in the form of mud along with other elements. To this channel some Copper and Lead Circuits effluents arrive. The mud contains metals that must be re used. Implemented Tasks To prevent the metals contained in this effluent from ending at the Mantaro river through the main channel No. 1 a mud retention system has been implemented at the Agglomeration plant. It consists of one floodgate, one retention tank that through a pump is sent to a thickener where the solids are separated in water suspension. The underflow that contains the mud is sent by gravity to the 81 band for humidification of particles transported they then return to the Agglomeration Machine. The clarified water that is stored in a tank is reused at the Agglomeration Plant gas washers. The implemented work has been done using the company's own materials, such as tubes, accessories and pumps in such a way that the cost will be minimal. Zinc Circuit a) General Process Description The Zinc concentrates coming from the Paragsha and Mahr Tunel Production Units are treated at the two roasters circuits: One Fluid Bed and the other a Turbulent Bed. The calcine is obtained as the product of this stage, subsequently the calcine is leached to make soluble the oxide and the zinc sulfate. During roasting the SO2 gasses are produced previously having passed through a dust precipitation stage. At the roaster turbulent bed, Sulfuric Acid is produced having a commercial grade. The calcine leaching process is accomplished at agitators tanks using as a leaching solution the used electrolytic and the sulfuric concentrate acid. After solid liquid separation a "solid residue" (zinc ferrites) is obtained which is subject to flotation to obtain Zn-Ag concentrate. 26% of this process tails are treated at the Zinc Residues Leaching Plant and the rest of the residues are sent to the Huanchan deposit. The impure solution, the other solid - liquid separation product, is taken to a purifying system where by zinc dust addition precipitates in form of copper, cadmium impurities and lower quantities of antimony and arsenic. This solution is filtered and the solid residue is sent to the "Cadmium Plant" for treatment. The purified solution is sent to electrolytic cells, those cells use aluminum cathodes and silver-lead anodes. After a deposition period of 16 hours the cathodes are extracted form the cells and the zinc de-laminated to finally be subject to an Induction Furnace obtaining refined zinc of 24 kg to be commercialized. The precipitation obtained at the purification stage is treated at the "Cadmium Plant" where "metallic cadmium" is obtained after series of leaching, precipitation, briquette and fusion processes. At the Zinc Residues Leaching Treatment Plant (Zileret) through reduction and oxidation processes iron is separated as iron sponge and copper, zinc cadmium and indium as oxides (fumes). At the Zileret Hydro - metallurgic Unit the oxides are subjected to hydro metallurgical processes with the aim of recovering the heavy metals, obtaining as a final product a torta de zinc sulfate, a zinc sulfate solution and a indium cement which are sent respectively to lead beds, zinc electrolytic plant (leaching plant) and the indium plant. The Indium Plant treats the cement coming from the Hidro- metallurgical Unit, where through the hydro metallurgical processes (acid and basic dissolution by solvents extraction, precipitation, etc.) and pyro metallurgical processes metallic indium is obtained. b) Effluents Management o Overflow Leaching Solution and Zinc Purification Solution; Code 126 This effluent collects the solutions of the house cells, purification overflow section, rectifiers water and hygiene services. It contains approximately 36% of the Total Manganese and 30% if the total zinc. Arithmetic Average March 94 February 95

Tasks to be Implemented This effluent is treated at the Treatment Final Effluent Plant by Neutralization and Selective Precipitation. PROJECT: Final Effluent Neutralization and Selective Precipitation Antecedents: With the present monitoring data the flow and the concentration of each of the contaminant effluents are being estimated, taking out the cooling effluents that are being poured to those effluents. With the data obtained a material balance has been applied to get to know the final pouring that would result if all the contaminant discharges are united. Due to the lack of space at the smelter and due to treatment improving reasons all the contaminant effluents are collected to be treated out side. This effluents are the following 112 - 115 - 117 - 119 - 121 - 123 - 124 - 126 - 135 - 137. (EVAP Codes) The selected area is Cochabamba, where the company has planned transferring the ferrites and slags. Tubes will be installed from the beginning. Studies: The study has been done by the consulting firm Ecolab S.R.L. Objective: Preclude the discharge of contaminated waters to the Mantaro River. Project Description: a) Effluent Transportation to the Treatment Area The smelter contaminant effluents would be collected at one point to be taken to the Cochabamaba Deposit through 2 PVC tubes of 8" diameter. The transportation system will be a railroad parallel line at 11 kilometers of distance. It will not be necessary to use pumps because the natural slope facilitates transportation by gravity. b) Neutralization Stage by Lime The neutralization system at this stage will consist of the following sections: o Storage of solid lime. With the objective of stopping dust emission into the atmosphere a reception tank will be installed with lime storage of 10 t. capacity. o Lime Lechada Preparation. From the storage tank and with help of a transportation band "Lime" will be distributed conveniently to the lechada preparation tank, (1 m3 capacity). Where part of the already treated final effluent will be added, registering a pH = 10 with the objective of reducing lime consumption. To maintain the lechada in suspension and homogenous an agitator will be installed. o Lechada Distribution. The Lime lechada will be fed with an automatic distributor to the neutralizer tank. This operation will be controlled by a pH meter, that will be installed at the tank's exit in a way that the addition will be done in relation to the pH required. It has been calculated that the lime consumption will be 375 Kg. Per day c) Neutralizer Tanks With the objective of achieving a efficient contact between the lechada and the effluent, it has been considered to install 2 tanks with agitators to homogenize the contaminant effluent and the lime quality until reaching a 7 pH. The solution under this conditions will be discharged in the settling tank. d) Settling Tank and Mud Storage At this stage the separation of the solid-liquid by settling will be produced. The solids will accumulate at the bottom of the tank and the purified solution will be sent to the following value recovering stage. The solids that accumulate at the tank will remain there in definitively. Due to the mud characteristics at this stage, this stage will make the tank bottom water proof which will preclude the solutions filtration. The objective of elevating the pH up to 7 is to achieve the effluent acid neutralization, precipitating some elements as Mn, Fe, Cu Al, etc. reducing the reagents consumption and recovering at the following stage the Cd and Zn that could re circulate in the Zinc Circuit. e) pH Regulation Stage The effluent that comes from the settling tank still has some significant concentrations of Cd and Zn to be recovered. The pH will be increased up to 10 with caustic soda with the objective of precipitating them as hydroxides. At the same time the pH will precipitate the residual Mn, Fe, Cu. The solid soda will dissolve in a 500 liters capacity tank. From the tank it will be distributed with a pump up to the mixer channels (two units) where they will be homogenized with the effluent passing to the settling tank. A pH meter at the end of the channels will control the soda distribution. Part of this effluent will be re circulated to prepare the lime lechada solutions and the sodium hydroxide. Project Duration: The implementation of this project is estimated in one year. Cost: The execution cost for this project is US $ 2 500 000.00 and it will be with the company's own resources. o Washing Anode Effluent Code 124 PROJECT: Automatic Washing Anode System Antecedents: In the cells house at the Zinc Electrolytic Plant an acid effluent is produced from the anodes wash. The washing effluent contains solids in suspension (manganese dioxide) which are retained in a settling device, the remaining water is discharged with no other treatment into the Mantaro River.

Work to be Implemented The same as the X effluent or the Lime lechada neutralization proposed by the Metallurgical Research Office. Copper Refinery a) Process Description At the Copper Refinery the blister copper anodes coming from the Copper Smelter are subject to electrolysis process, obtaining refined copper cathodes. This copper is sold as smelted cathodes or as wire bar. The electrolytic is bled of daily separating 30 000 liters/day approximately to maintain the range of impurities required by the process. This solution is saturated by neutralization with iron scarp at the refinery and evaporation to produce copper sulfate with a commercial grade. 75% of the solution returns as electrolyte and the remaining 25% is subject to cementation to recover the copper with iron scarp. The final solution for now is being discharged at Yauli river. The anode mud obtained at the electrolysis stage is treated at the Anode Residues Plant; gold, silver, selenium, tellurium, and bismuth are obtained. Refined copper cathodes obtained at the electrolytic cells after being washed are sent to the Copper Fusion and Casting Section where they are smelted in an ASARCO vertical column furnace and cast in different forms: Wire Bars, Copper Pechos, 5" Ingots, Channels, Casts for Copper turntables. Finally some copper bars are converted to copper wire of 5/16" or 9/16" of diameter. b) Effluents Management o Mother Water - Code R 4 PROJECT: Copper Refinery Mother Water Treatment Antecedents: The Copper Refinery mother water is a product of bleeding of the electrolyte 30 000 l/d, the house cells, and commercial tanks. It is subject to neutralization, to vapor heat and saturation with copper waste, copper cement, copper oxide and oxidation with air. The product is discharged into the reception tanks and from there to the crystallizer, the crystallizer discharge is subject to a centrifugal to separate the copper sulfate crystals and the mother water solutions. Part of it is re- circulated to the neutralizer and the other is stored at a 22 000 liters tank, which is heated before passing by the copper precipitation tanks, where iron virtua is added to obtain copper cement. The precipitator tank barren solution (7 000 l/d) is finally taken to the Lead Refinery settling tank. Before was used to recover the Lead from the Refinery Discharge Lead Solution. A Lead Refinery electrolytic recovering system has been implemented. (From June 7 1996) It has re circulation inside the operations, the Copper Refinery mother water remains to be treated.

With this the effluent that was going form the Alambron Plant to the Yauli river was eliminated. This action also allowed to recover the copper that was lost in a oxide appearance. Lead Refinery a) Process Description The Bullion Lead produced at the smelter with antimony content (Sb), Bismuth (Bi) and Silver (Ag) is refined by an electrolytic process using a modification of the Betts Method. The corroded anodes are left with not soluble impurities which are attached to its walls Having the electrolyte on them it is necessary to wash them by immersion to recover the electrolyte. The mud is detached with pressure water (130 000 l/d). The pulp is settled and filtered obtaining humid anode mud (12%) which is derived to be treated at the Anode Residue Plant. The discharge solution is re - used in the preparation of reagents for the immersion washing and the pressure washing. The emission of this effluent to the Yauli river has been controlled. After the cathode deposition required period, the cathodes are removed from the deposition washing cells to recover the electrolyte and to be smelted at one of the three 160 tons pans that are heated with oil. The smelted lead is heated up to 450 (degree) C and vigorously shaken with sodium hydroxide (Na OH) to skim the arsenic, antimony, and remaining tin. The refined lead is cast in bars of 46 Kg to be commercialized. The fluorsilicic acid required by the electrolysis process is fabricated making the flour calcium (CaF2) react with the sulfuric acid (H2SO4) to obtain the Fluorhydric acid (HF), which will react with the silica (Si O2) in one reactor. b) Effluents Management o Lead Refinery Electrolytic Cells Effluents - Code R1 Starting from June 7 of 1996 the Fluorsilicic acid recovering conventional system has been replaced by one that includes a automatic filter "Lerox". The mud anodes that are sent to the Anode Residue Plant to recover valuable metals humidity has diminished. The discharge solution is being used in the preparation of reagents, for the immersion washing and for the pressure washing of corroded anodes. There is no longer an emission of this effluent to the Yauli river. Services and Shops a) Process Description The metallurgical complex is various plants require workshop participation to develop complementary specialized works such as installations, maintenance, and electric motor repairs, instrument repair, carpenter work, masonry, motorized vehicles, etc. For this purpose there are Instrumental Shops, Structural Shops, Storehouse, Buildings and Land (carpenter and masonry), etc. The effluents that are generated at these shops are coming principally form the hygiene services. b) Effluents Management o The effluents coming from the storehouse, structural shops and carpentry shop, hygiene services. This effluent is discharged directly to the Mantaro River. o Implemented Projects These effluents are collected and treated at a two cameras pilot septic tank before it gets evacuated into the Mantro river.

* Source EVAP La Oroya Metallurgical Complex PROJECT: Smelter Cooling Water Re circulating System 1. Introduction Today the water used for cooling the industrial processes at La Oroya smelter is totally discharged at the Mantaro River, through open channels or tubes that flow throughout the smelter industrial installations This cooling waters mix in some cases with domestic and industrial effluents, increasing the volume of the polluted water. In other cases the cooling waters are contaminated only by passing through industrial areas due to the presence of dust, solids and gasses. To resolve this problem two alternatives have been proposed. The first consists of separating the cooling waters from the industrial effluents and from the sewage waters, constituting an independent system that will discharge into the Mantaro river. The second alternative that we consider much more achievable consists of building a new web to re circulate the water to the Smelter through the Mantaro Pumps. 2. Objective o Protect the refrigeration from the contamination sources that exist at the Smelter environment. o Recover approximately 2253 gpm, of good quality water, through the re-circulating supplying system using the Mantaro river Pumps. o Improve the quality of the water supply coming from the Mantaro pumps to the Smelter comparing them with the river water quality. o Guaranty the water supply to the Smelter in times of freshet. 3. Project Description For re circulation, the cooling water will be taken from the different discharge points throughout a hydraulic system by gravity in tubes of different diameters. The water will pass through different industrial zones of bigger discharges and will be conducted to the Mantaro pipes.

It is necessary to indicate that the waters do not require a cooling system due to the web characteristics and to the distribution system that allows the water to reach normal temperatures. This will not be possible in the case that re circulation would be at each plant requiring complicated and costly systems. 4.

The excavation will start when the tubes are at the project. The ditch will be minimum 0.40 meters and maximum 0.70 meters wide. The bottom will be leveled following the tube and hood thickness. The excavation excess will be refilled with river cement. The tubes will be covered before setting them in the ditches, removing the ones that have cracks or defects. The hoods will be oriented upwards. 4.4 Leveling The tube leveling will be performed with a topography instrument. At the union it will be checked that the tube surface and the hoods are clean. The filling of ditches will be executed after the hydraulic tests are made at the installed tubes, first with selected material (No stones, roots, grass, etc.) continuing with 0.10 meters layers trying not to move the tubes until an altitude of 0.30 over the tube edge, finishing it with material free of stones. For tube union stretches that have no hood pre - fabricated unions will be used. 4.5 Estimated Cost Description Cost US $ - -------------------------------------------------------------------------------- Item Description Cost US$ - -------------------------------------------------------------------------------- 100 Preliminary traces 5 500 400 Mechanic Installations 32 092 Sub Total 37 592 Contingencies 10% 3 758 Total 41 350 - -------------------------------------------------------------------------------- ------------------------------- ANNEXES ------------------------------- 5.4 Soil Impact Control The solid residues exposed to the open environment suffer degradation by oxidation and leaching, originated by the rain water. This action dissolves by filtration and infiltration some elements that discharge to the Mantaro River through the underground water.

Projects to be Implemented PROJECT: Copper and Lead Slag Management and Disposal 1. Introduction In all the copper and lead smelting processes slag is produced. They have a low commercial value due to their very low valuable contents and or the high fusion point required - 1250 (degree) C. At La Oroya metallurgical Complex slag is obtained from the lead vertical furnaces and the reverber furnace. They are in a liquid state at 1 100 (degree)C and 1 200 (degree) C respectively. Slag is rapidly cooled down through water pressure and transported by gravity in "slurry" form, rectangular channels up to a "tolva" battery where liquid - solid separation is undertaken. Slag is deposited at the bottom of the "Tolvas" and sent by cable cars to the "Huanchan" deposit which is 2,2 kilometers away crossing the Mantaro river. This transportation system operated from 1930. Today it is obsolete, having serious operational, maintenance and transferring problems. The water used in granulation is discharged directly to the Mantaro River taking with it fine slag and / or suspended or diluted metals generating a very serious contamination problem. PAMA - La Oroya has considered a study developed by the CENTROMIN S.A. Project Section at a basic engineer level. The study gives a solution to the water generation, recirculation problem and also to the slag transportation problems. In this way the Mantaro river contamination produced by these solids will be stopped. 2. Present Situation Analysis Actually the system shows the following situation: 2.1 Granulation system: o Operation Time The reverber slag discharge is not continuous, the normal cycle is usually 4 hours of discharge and then one hour stoppage until it starts again. For the Lead Slag the discharge runs continuously 24 hours. o Water Quantity At present the water is used in the following quantities: To granulate copper slag: 5 000 gallons per minute. To granulate lead slag: 3 000 gallons per minute. o Water Characteristics Before granulation the water temperature is in the 10 to 14 (degree) C range depending on the season, after these processes the water reaches 28 (degree) C. The chemical analysis shows lead presence, arsenic, copper, iron and some suspended contents that in some cases are over the Maximum Permissible Levels. o Vapor The water vapor is product of granulation, it discharges directly to the atmosphere. It must be taken into consideration that the environmental rules do not register emissions, but a stronger control should be expected in the future. 2.2 Transportation System o Equipment The transportation equipment "cable car" dates form 1930. It has been design for 500 t/d production capacity. Its obsolescence creates multiple operational and maintenance problems. Increasing its transportation capacity is not possible due to its design, age and condition. o Capacity The present system does not allow transportation of 1 100 t/d of slag to the area of "Huanchan". This is not only true because the equipment but also because its limited storage capacity and slag reception tolva retention, that feeds this equipment. The above allows to conclude: - It is necessary to modify the slag management system: generation, transportation and storage. - It must be contemplated in addition to the modifications, a closing plant or stock abandonment as one of the alternatives for the solution of the environmental problems. 3. Project Objectives The project pursues the following objectives: o At the Slag Generation - Stop more slag waste at the granulation stage. - Re circulate the process water in a closed circuit o Mantaro River Discharge - Eliminate the discharge to the Mantaro river by having an adequate solid liquid separation. - Eliminate the discharge of contaminated water into the Mantaro river by making possible its re-circulation after achieving its objective at the granulation stage and slag haulage. o Transportation and Storage Allow transportation of the totality of slag generated and achieving an adequate storage, at Huanchan or some other sector. 4. Project Justification The project is justified because it will solve the following problems: o Liquid Contamination Avoid discharge of contaminated water produced by granulation to the Mantaro river. The water contains solids in suspension and or contaminant ions that are produced when slag is granulated. o Solid Contamination Avoid the part of the solid slag deposited in the Mantro River by transporting the totality of the quantity produced to a suitable storage site. o Populated Areas Impact The Mantro river is the main vital sign of the central region as it, supports many valleys. Avoiding its contamination is urgent. o Lack of Technology The implementation of a modern system will permit: - Evacuating all the solid slag. - Re-circulation of granulation water - Diminished the water consumption. 5. Project Description 5.1 Characteristics The project considers the acquisition and installation of the following: o Solid Liquid Separation System The installation of 2 rotator discharged INBA of high technology with a new granulation system that uses one portion of slag water from 10 to 1 in weight. With this project the water will be continuously re circulated avoiding Mantaro river contamination. o New Transportation System The system will be design to transport 1 400 t/d exceeding significantly covering the present production of 1 100 t/d The solution will consist of the installation of transportation bands, that will allow the transportation of the totality of slag up to the left margin of the Mantaro river to be finally disposed 5.2 Investment Budget The work involved for the project implementation has the following details: ----------------------------------------------------------------------- DESCRIPTION AMOUNT US$ ----------------------------------------------------------------------- 1.0 Solid - Liquid System Water granulation 3 900 000 and re circulation ----------------------------------------------------------------------- 2.0 Transportation System 1 708 000 ----------------------------------------------------------------------- SUB TOTAL 5 608 000 ----------------------------------------------------------------------- Contingencies +/- 15 % 892 000 ----------------------------------------------------------------------- TOTAL 6 500 000 ----------------------------------------------------------------------- 5.3 Execution Chronogram The project execution schedule estimates that it will require 3 years as follows: - -------------------------------------------------------------------------------- YEAR ACTIVITY AMOUNT US $ - -------------------------------------------------------------------------------- 1997 Solid Liquid Separation Fabrication 1 494 000 - -------------------------------------------------------------------------------- 1998 Additional Equipment Acquisition Separation 3 362 000 System Installation - -------------------------------------------------------------------------------- 1999 New Transportation System 1 644 000 - -------------------------------------------------------------------------------- TOTAL 6 500 000 - -------------------------------------------------------------------------------- 6. Mitigation Proposed This project answers the urgent need to reduce substantially the Mantaro River contamination, which at present is created by the slag handling. 7. Economic Analysis The project execution does not foresee an immediate economic return, but it is considered it will highly contribute to diminish the environmental impact today present not only at the Mantaro river but also for the central region flora, fauna and human habitat. 8. Conclusions The implementation of the present project makes it urgent especially having the following objectives: - Eliminate the Mantaro river contamination created by the solid discharges and contaminated water. - Guaranty the operational continuity of the Copper and Lead Smelter having a modern system of slag management. PROJECT: Copper and Lead Deposits Abandonment Study 1. Introduction Slag consists of disposable residues obtained at the La Oroya copper and lead smelter processes, which are sent to the Hanchan deposit located 2,2 kilometers from the smelter at the left margin of the Mantaro River. This residues are black and with the texture and size of sand. They are transported to the deposit at an average of 600 tons a day, with the help of the cable cars. Its final disposal is done through bands discharging them "free downfall" forming cones of approximately 70 meters in height. The deposit which has been used from 1930 presently stores 10 million tons of copper and lead slag. It has a remaining a useful life of 7 years. Due to its age, design and type of operation, the deposit does not comply with the environmental control government demands. It does not have the stability safety conditions. This situation originates the Mantaro river contamination, the possible deposit collapse, and the need of having a new storage area due to its limited life time for future abandonment of the deposit. PAMA La Oroya has considered a study that is being developed by RESCAN PERU S.A. at a basic engineer level that will allow to have a solution to the above mentioned problems. 2. Present Situation Analysis The deposit presents the following situation: o Age o The operation has been running for a significant period of time and the big volumes deposited in piles of high altitude present an unsafe situation in respect to stability. There are not geo-technical studies relating to the soil where the deposits are located. o Storage System o It is very limited due to the "cable car" which is from 1930. It is not capable of transporting all the slag produced. The slag disposal at the place is done through transporting bands, they do not have determined heights. o Contamination o The nearness of the deposit to the Mantaro Rivier makes the river vulnerable to contamination especially for the following: o The slag water which carries fine slag particles drains naturally gets to the Mantaro river. The escorrenteria water have the same effect as the one mentioned above. Infiltration exists naturally and it is probable that part of this water contributes to the liquid flourishes that show at the river lateral sides. Winds give rise to slag sand migration. 3. Project Objective The project will accomplish a slag Huanchan deposit analysis, that will permit design of a closing plan up to the basic engineering level, considering the stability aspects, remaining capacity, liquid and solid contamination, soil recovering and remedy. The site of the new deposit will be also analyzed . 4. Project Justification The project must be implemented because the following reasons require immediate attention and constitute the elements that affect the environment. There is also no guaranty of Hanchan deposit stability. o Contamination It is necessary to minimize the Mantaro River contamination due to the characteristics and magnitude of the deposit. The deposit is the solid and effluent contributors that flow toward the river, especially in rainy season. o Stability Due to the height reached by the storage piles (more than 70 meters in some cases) it is not possible to guaranty stability and dynamics of the piles in case of overweight or earthquakes. Additionally, there are no geo technical, hydride and or seismic studies. Moreover, it must be considered that La Oroya is considered a high intensity seismic zone. o Operativity The deposit life time is lower that 10 years. This situation compels the start of studies as soon as possible as well as the work needed in order to close the deposit and build the new one. 5. Projected Characteristics 5.1 Characteristics The projected closing plan has a variety of measures and engineering work to be executed, so that the total abandonment of the deposit will have the following characteristics: o Physical Stability Considers the work to be done to and guaranty the deposits stability in case of collapse, pluvial erosion, and environmental erosion in case of reasonable seismic occurrences and extraordinary rain. For this development it has been executed and it is being executed studies related to the following aspects: - Hydrology and Seismic Activities - Embankments Stability - Growing Potential and Remaining Capacity - Stability against pluvial escorrenteria - Infiltration Control - Eolic Erosion Stability o Effluent Control If it is confirmed that the drainage water escorrentias and the solids pass over the contamination permissible limits, those waters will be conducted to a corresponding treatment tank. o Environmental Control Measures After Closing This measures correspond to all steps that must be taken to accomplish the effluents stability and control, after closing. This will verify anomalies that must be corrected in time to guaranty the environment conservation. o New Slag Deposit Define all the implementation works needed for the Cochabamba new deposit. The deposit will be located 9 kilometers from La Oroya on the road to Huancayo. The new deposit will have all the safety and environmental controls required for a safe environment. 5.2 Investment Budget The work involved for the project implementation will have the following details: - ------------------------------------------------------------------------------- DESCRIPTION AMOUNT US$ SUB-TOTAL (US$) - ------------------------------------------------------------------------------- - ------------------------------------------------------------------------------- 1.0 New Deposit at Cochabamba 2 200 000 2 200 000 - ------------------------------------------------------------------------------- 2.0 Existent Deposit - ------------------------------------------------------------------------------- 2.1 Protection and Stability Work 2 000 000 - ------------------------------------------------------------------------------- 2.2 Complementary Work 550 000 - ------------------------------------------------------------------------------- 2.3 Treatment and Restoration 2 000 000 4 550 000 - ------------------------------------------------------------------------------- Sub total 6 750 000 - ------------------------------------------------------------------------------- Contingencies +/- 15% 1 000 000 - ------------------------------------------------------------------------------- TOTAL 7 750 000 - ------------------------------------------------------------------------------- 5.3 Execution Schedule The execution time table estimated to be 3 years. - ------------------------------------------------------------------------------- YEAR ACTIVITY AMOUNT US$ - ------------------------------------------------------------------------------- 1997 Existing Deposit, work stability 1 250 000 - ------------------------------------------------------------------------------- 1998 New Deposit 2 500 000 - ------------------------------------------------------------------------------- New Deposit Protection and Treatment and 2 500 000 others - ------------------------------------------------------------------------------- 1999 Recuperation and Remediation 1 5000 000 - ------------------------------------------------------------------------------- TOTAL 7 750 000 - ------------------------------------------------------------------------------- 6. Mitigation Proposal The project is the answer to the urgent need to reduce contamination at the Mantaro River and guaranty the deposit stability before any collapses occurs. It will start the closing of the deposit, its restoration and the remediation of the area. 7. Economical Analysis The project execution does not foresee an immediate economic return, but it will greatly contribute to reduce the environmental impact presently affecting the area, not only the Mantaro River but also the flora, fauna and human habitat of the Peruvian central region. 8. Conclusions The execution of the present project is urgent taking into consideration that it will: - Eliminate the Mantaro River contamination produced by solid discharges and contaminated water. - Guaranty the deposit stability and will assure the continuance of the Copper and Lead Smelter. - Guaranty the deposits stability and the Lead & Copper Smelter continuance of operations, during the its remaining life time. - Initiate the "Huanchan" deposit closing plan. PROJECT: Arsenic Trioxide Abandonment Study and New Deposit Location 1. Introduction The copper smelter -La Oroya- operations generate solid residues. Arsenic trioxide is one of the most important solid residues due to its high toxicity for human beings. This residue is a white fine dust (malla - 400) with a high solubility. It was started to be deposited in 1922 at a deposit located 19 kilometers from La Oroya City near the Malpaso hydroelectric. After 25 years of operation the deposit was closed, starting operations the present "Vado" deposit 9 kilometers from La Oroya near to the old airport. This deposit were built under the standards of the time, they do not comply with today's environmental requirements, especially because they are located in alluvial areas very near the Mantaro river. The contamination created is represented by an arsenic concentration increase in the river water. The increase is produced by dissolution, percolation and residual hauling by eolic action over the trioxide present in the Vado area, because the deposit is not covered. PAMA considers a study that is being developed by ADI INTERNATIONAL INC at a basic engineering level. The study will give solutions to the contamination and location problems related to this toxic residue. 2. Present Situation Analysis As a result of significant quantities of arsenic in the concentrates that are treated at La Oroya smelter "arsenic trioxide" is produced. This product due to market restrictions regarding its quality and volume is practically impossible to commercialize. Situation that creates an need for storage space, the residue is being stored at the old Malpaso deposit. This deposit is not operating these days, it contains 40 000 tons of residue covered with material that is found at the surroundings areas such as stones and clay. The present operative deposit is Vado deposit which contains 150 000 tons, it is an open deposit exposed to rain and wind action. The environment is being affected by these deposits. The Mantaro river and the areas around it are being polluted with consequences that could be highly dangerous not only for the flora and fauna but also for the human beings. Arsenic trioxide is considered a "poison solid". This situation makes the engineering studies imperative in order to have solutions at an international level that will allow us to solve the abandonment problems and the build the new deposits. 3. Project Objectives Developing the engineering studies, for the Malpaso and Vado deposits abandonment as well as for the construction of a new deposit at the old airport area, allowing the implementation of solutions at an international level. These studies will consider hydro geological geo technical conditions at the areas of interest. This project will observe PAMA requirements . 4. Project Justification The development of this project is highly urgent given the environmental contamination characteristics in areas around the Mantaro River. Due to the river contamination the health and life of the population is at risk, as is the case of Pacha town. 5. Project Description After the analyzing different solution alternatives available from a technical economic point of view, it was determined to use solutions that will be in accordance to The Environmental Protection Agency of the United States (EPA) and the Environmental Ministry Canadian Counsel. (CCME). 5.1 Characteristics Malpaso Deposit The system consists in covering all the stored residues with a double water proof covering, a geo-textile coat for the upper part and a membrane for the lower part. It will have some additional clay coats and sand for protection as well as a drainage system. First the site and platform will be pre conditioned. An open cell will be built at the upper part where the residues will be placed for a final seal. To start the solution implementation a transitory zone must be arranged where part of the residues that will be placed in the cell will be removed. The cell after it is sealed and covered with the material we have already specified will be under ground, the area esthetics will be intact. Vado Deposit The capsulate work will be similar to the one at the Malpaso deposit. It could have as a temporary zone at the new deposit. This work can also be executed in modules. New Deposit At the old airport and with the same capsulate modules technique as in the cases detailed above an area will be determined and the work will start for the cells production. The production of arsenic trioxide is 4 000 tons a year ,the projected area for the new production will be for a final volume of 50 000 m3 having a life time of 25 years. Remedial Action The old deposits area after the work is completed will have a natural appearance, similar to the surroundings. The project considers the total remediation of the affected areas. 5.2 Investment Budget The works involved for the project implementation will have the following details: - ------------------------------------------------------------------------------ DESCRIPTION AMOUNT US$ - ------------------------------------------------------------------------------ 1.0 Malpaso deposit Shut Off 2 800 000 - ------------------------------------------------------------------------------ 2.0 Vado Deposit Shut Off 4 800 000 - ------------------------------------------------------------------------------ *3.0 New Deposit 1 750 000 - ------------------------------------------------------------------------------ SUB TOTAL 9 350 000 - ------------------------------------------------------------------------------ CONTINGENCIES +/- 15% 1 350 000 - ------------------------------------------------------------------------------ TOTAL 10 700 000 - ------------------------------------------------------------------------------ * Amount to be invested in a 10 year operation period. 5.3 Execution Schedule The project execution schedule will require five 5 years under the following details: - -------------------------------------------------------------------------------- YEAR ACTIVITY AMOUNT US$ SUB TOTAL US$ - -------------------------------------------------------------------------------- 1997 Malpaso Deposit 2 600 000 2 600 000 - -------------------------------------------------------------------------------- 1998 New Deposit 2 000 000 - -------------------------------------------------------------------------------- Malpaso and Vado deposits 2 600 000 4 600 000 (cont) - -------------------------------------------------------------------------------- 1999 Vado (cont.) 2 000 000 2 000 000 - -------------------------------------------------------------------------------- 2000 Vado (cont.) 1 000 000 1 000 000 - -------------------------------------------------------------------------------- 2001 Complementary Works 500 000 500 000 - -------------------------------------------------------------------------------- TOTAL 10 700 000 - -------------------------------------------------------------------------------- 6. Proposed Mitigation The proposed solution will solve the contamination problem, abandoning the existing deposits using the latest technology and building the new deposit that will meet the required guaranties. 7. Economic Analysis The project characteristics with which the old contamination problems will be solved are not directly related to the present production process, not allowing an economic quantification for its profitability. But an ecology contribution can be stated, meaning a positive contribution to La Oroya city and its surroundings. 8. Conclusions and Recommendations The project will solve the arsenic trioxide contamination problems completely and with modern technology, liberating the Malpaso and Vado storage deposits. The project has been designed to be executed in stages which could start working independently. It will be essential before starting the pertinent work to make arrangements with the local authorities and government with the objective of taking the necessary safety steps preventing in this way problems with the people and the on going capsulate individual works. PROJECT : Leaching Zinc Residues Temporary Closing Plan 1. Introduction The refined zinc is obtained from the sulphurated concentrates at La Oroya Metallurgical Complex. It is obtained by using the Electrolytic Method which uses only one leaching stage named "Neutral". This is different form all other plants in the world where two or three additional and much more energetic stages are used. Under this condition the zinc dissolution starting from the calcines are limited to the zinc oxide, leaving the zinc ferrites as the big residue component evacuated at this stage. The presence of the zinc ferrites is due to iron contents in the concentrates that are processed in Paragsha and Mahr Tunnel and naturally inherent to the mineral deposits mineralogy where they come from. The lack of technology that will allow an economic benefit of the zinc residues neutral leaching (RLNZ) have required storing them in fields at the Huanchan area. Starting from the 50 `s the totality of the generated residues were sent to the deposit. Although from 1968 with the implementation of the pilot plant for the treatment of 50 th/d of RLNZ only 70% of the RLNZ produced were sent to Hanchan. At present Huanchan has 1 240 000 tons of RLNZ stored using for transportation a pulp pumping system because it is the most practical and economic. Due to the years of operation, the type of residues (containing high value metallic elements), the Mantaro river contamination and the deposition tanks stability it is compelling to make a study that will consider the most important factors such as: First, the one related to the zinc ferrites treatment feasibility; and Second, the deposit temporary closing and final shut off, with the objective of guaranteeing its stability and minimizing contamination that might be generated. Under this project two studies are been executed: The deposit's temporary closing plan given to Rescan Peu S.A will be developed to a basic level of engineering. 2. Present Situation Analysis The source of contamination is the zinc sulfate presence at the pulp water phase that is sent to Huanchan (at present it has 1 g/l zinc level but in the past they reached 5 g/l). It is drained to the Mantaro river after a natural settling of residues. The solution registers solids in suspension. Part of the zinc sulfate remains at this place while the RLNZ humidity crystallizes. It dries with the residues and re-dissolves by rain action. It is then carried by eolic effect into the Mantaro river. This operation has compelled to elevate the dike contention walls at the storage tanks which has created a collapse risk in case of a seismic event or other disaster. Up to this date, tanks 1 and 2 have reached 6 meters and tanks 3- 4 reached 11 meters over the natural landscape. At the deposit at the Mantaro left lateral side numerous eroded carcavas by pipe discharges coming from the decanting tanks and filtration of undetermined origin. At present, there are no stability studies. It has not been defined the origin of the filtration phenomena, to see if they come exclusively from the Ferrites tanks or they are a combination with the ones coming from the adjacent slag deposit. In light of this situation, while the studies are made and the economic reprocessing of the RLNZ technology is implemented a temporary closing for these deposits is considered. 3. Project Objective The objective is to have a feasibility study that will permit an estimate of the RLNZ reprocess pre selected technology applicability and its profitability. If the project is viable, after its implementations at an industrial level, contamination will be eliminated by making zinc ferrites part of the new process; with a much lower residue generation in a stable phase. The ferrites deposit temporary closing plan study research is at present in execution and will allow a static stability and a tank dynamic analysis, the determination of the Mantaro river contamination and the definition of work, installations and equipment necessary to conclude successfully the temporary deposits closing, besides having the possibility of treating in the future the stored ferrites. 4. Project Justification The liquid and solid contamination that the soluble salts and RLNZ generate is worsened by the deposits location at the Mantaro river shores. The dike connecting system and the eolic wind action make it necessary to guarantee the deposits stability in case of climatic factors that could affect them. On the other hand, the value of the high metallic contents such as Zn, Ag, and Cu make it necessary to study the possibility of reprocessing. 5. Project Description 5.1 Characteristics o RLNZ Reprocess As a possible additional investment the project considers RLNZ benefit using the "Lanza Sumergida" technology. This technology has an Australian patent, property of AUSMELT LIMITED enterprise, same company that is elaborating the feasibility study. The reprocessing plant is being projected for 480 tons/day of treatment capacity and it must be capable of processing the residue generated by the current operation and part of the residue already deposited at Huanchan. In such a way that in 10 years the residues would be totally consumed and this source of contamination will be eliminated. This technology is in a commercial implementation process, its possible investment has not been considered in this PAMA. o Temporary Closing Plan The second part is planned as a deposit temporary closing. It is constituted actually by 6 tanks (1, 1A, 2, 2A, 3, and 4) comprising a group of measures and engineering works that must be executed in brevity with the aim of mitigating the environment impact and guaranteeing the tanks's stability. The plan's most relevant characteristic is that failing the technical and economical feasibility of the Zn ferrites treatment the closing solution will be final, having the future possibility of recovering the valuable contents, especially zinc. 5.2 Investment Budget According to the estimated investment amounts given by the consulting firms that are making the studies. The following figures are presented o RLNZ Reprocessing For the Implementation of this system the following investment is estimated: - -------------------------------------------------------------------------------- Description Amount US $ - -------------------------------------------------------------------------------- 1.0 Facilities Construction for the AUSMELT Equipment 15 000 000 installation. - -------------------------------------------------------------------------------- 2.0 Mechanical, Electric and control installations. 15 000 000 - -------------------------------------------------------------------------------- 3.0 AUSMELT Equipment 48 500 000 - -------------------------------------------------------------------------------- 4.0 Complementary works 500 000 - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- SUBTOTAL 52 000 000 - -------------------------------------------------------------------------------- CONTINGENCIES 15% 8 000 000 - -------------------------------------------------------------------------------- TOTAL 60 000 000 - -------------------------------------------------------------------------------- o Temporary Closing Plan This plan corresponds to the following activities: - ------------------------------------------------------------------------------- Description Amount US $ - ------------------------------------------------------------------------------- 1.0 Detailed Engineering 160 000 - ------------------------------------------------------------------------------- 2.0 Embankment Foot Wall Construction 2 570 000 - ------------------------------------------------------------------------------- 3.0 Geo membrane Water proof - ------------------------------------------------------------------------------- 3.1 Tank No. 1 and No. 2 40 000 - ------------------------------------------------------------------------------- 3.2 Tank No. 3 and No. 4 (the 4th year) 140 000 - ------------------------------------------------------------------------------- 4.0 Gravel Coating for Drainage - ------------------------------------------------------------------------------- 4.1 Tank No. 1 and No. 2 160 000 - ------------------------------------------------------------------------------- 4.2 Tank No. 3 and No. 4 400 000 - ------------------------------------------------------------------------------- 5.0 Conduction Channel towards the Settling and 116 000 Treatment Tank - ------------------------------------------------------------------------------- 6.0 Settling Tank and/or Treatment Escorrentia1 12 500 Water - ------------------------------------------------------------------------------- 7.0 Defense Walls for the River Margins 216 000 - ------------------------------------------------------------------------------- 8.0 Effluents and Filtration Capturing Boxes 5 000 - ------------------------------------------------------------------------------- 9.0 Effluents and Filtration Conducting Pipes 480 000 - ------------------------------------------------------------------------------- 10 Effluents and Filtration Treatment Tank 12 500 - ------------------------------------------------------------------------------- 11 Soil Restoration 400 000 - ------------------------------------------------------------------------------- SUBTOTAL 4 712 000 - ------------------------------------------------------------------------------- CONTINGENCIES 888 000 - ------------------------------------------------------------------------------- TOTAL 5 600 000 - ------------------------------------------------------------------------------- 5.3 Execution Schedule o 2 years are estimated for the RLNZ reprocessing, most of the time will be for the AUSMELT system which will take approximately one year. o For the temporary closing plan 7 months are estimated, except for the soil recovery that could take one to two years. 6. Mitigation Proposal It is fundamentally oriented to prevent contamination problems from the residues at the Mantaro river and to guarantee the storage tanks's stability in case of possible collapses, assuring by this the future use of the Ferrites. 7. Economic Analysis o Temporary closing is not profitable, but its costs can be covered if the resutls show that the AUSMELT or other reprocessing technology offers economic advantage. o The reprocessing alternative is based on the fact that the value contained in the RLNZ at market price reaches US$ 350/Ton of dry residue, having a processing cost of US$ 65/Ton of RLNZ +-30% and the capital costs of US$ 60 MM +/- 30%. Additionally, for a 10 year project lifetime period no longer than 4 years for capital recovery is expected. 8. Conclusion and Recommendation In conclusion, based upon the above, the Closing Plan will be executed in conformity with basic Engineering studies done by Rascan Peru S.A. consulting firm having a timing and definitive character depending upon the AUSMELT LIMITED feasibility study for the zinc residues neutral leaching reprocessing as a part of the present La Oroya Zinc Refinery. Finally, it is recommended that the execution of the pertinent studies and economic resources achievement should be expedited, in order to accomplish the temporary or definite closing according to the reprocessing feasibility of the huanchan zinc ferrites. 5.5 Air Quality - Area Affected by the Fumes (Erosion control - Sedimentation) The soils around the smelter's fume damaged area have suffered erosion action and the mineral elements have been washed by the rain. If rehabilitation is done through reforestation, it only can be accomplished by increasing the organic material. Additionally, it is necessary to use diverse techniques that will stop soil deterioration and help the spontaneous recovery as at it has been observed in the Huaynacancha area by the use of : Dike construction, carcavas modification and terraces construction. 5.5.1 Fume Affected Areas Study The affected area has not had a spectacular recovery compared with the one that it had between 1941 and 1971 (from 14 190 Ha to 4 170 Ha.) registering from that date to January 1996 an improvement of 3 829 Ha. The higher soil recovery time corresponds to the time that electrostatic precipitator implementations and improvements in the process was done, which had a rapid response on the limits of its actions. The recoveries up to 1971 have not had notable effects, passing the stated limits. It is not possible to ignore that the presence of vegetation at the nucleus of contamination is showing a slow spontaneous recovery which is much more observable in areas where reforestation has been accomplished. This is to show that recovery is going slowly, but going. The current recovery of the Vieja Huaynacancha area is good in respect to its condition in 1971, At that time no plant life was showing. Today a nice landscape with abundant plant life can be appreciated. Some other extended areas have a more limited recovery. On the had , bird are present and wild animals such as "jilgueros," "gorriones," "zorzales," ducks, and "huachuas" as well as vicuna herds induce us to think that the evacuated fumes are not as damaging as the ones in the past. There are extended, areas, where some work to recover vegetation can be experimented with. In some other areas soil can be broken to facilitate the absorption and retention of the pluvial waters and to prepare the soil for the natural dispersion of seeds. This is based on what has been observed at the differential zones where soil movement took place and where spontaneous covering was produced. Also reforestation must be not only at the embankments and at the bottom of the carcavas but also at the slopes that are abundant at the Hauynacancha zone. Plants of "doble repique" that are much more developed and strong should be used so survival is assured. It is possible to stop the formation of new carcavas and that the ones that already exist to stop growing by using adequate work described at the above paragraphs and populating the big cuenca de las carcavas with native or imported herbaceous vegetation, trees, and bushes with the objective of covering the nude areas and to stop erosion. At the slopes in front of the smelter it is possible to recover the natural cover with crops or some trees, since the soil analysis is favorable in its characterization and composition. All this will take time and investment that is shown in Table No. 5. 5.5.2. Environmental Impact Study Introduction The present study was given by CENTROMIN PERU S.A. to the Empresa de Servicios Ecologicos S.A. with the aim of developing a model for the dispersion of gases emitted by la Oroya smelter stack. The most important objective of the study is to analyze the different alternatives that will modify the main stack and reduce its high SO2 emissions. The visit to the metallurgical complex allowed us to observe the significant impact in the nearby areas coming from the pluma de gases emitted by the tack. At the same time the gases's impact at the smelter and adjacent areas was not higher. However, it also was observed that not only the smelter but also la Oroya city are seriously affected by gaseous emission coming from other sources inside the smelter (fugitive emissions and the ones coming from the secondary stacks). The advantage given by the stack height has been transporting the pluma of gases outside the smelter and city, which receive the impact coming out of the other sources of contamination. Gaseous Emissions Monitoring Data and Applicable Norms The monitoring data obtained related to gaseous emissions and the metallurgical complex air quality indicate clearly that the quality air norms and contaminant emission rules have been exceeded. It is required to implement measures and strategies to resolve this problem. The modifications at the stack will serve to approach the problems related to the air quality standards. Dispersion Model A dispersion model was used to compare the dispersion of the emissions coming from the main stack with the dispersion of various alternatives such as: a higher stack, a new stack located higher, a higher speed for the gasses' exit, a higher volume of gases emitted. A numerical model known as the ISC-3 (Industrial Source Complex Model version 3) was used. This model was developed by the Environmental Protection Agency of the United States of America (EPA) it is commonly used to model the dispersions at industrial complexes. Among the aspects incorporated to the model the stack dimensions and operational parameters, topographic information and meteorological data The model shows contaminants concentration predictions for the specific reception points adjacent to the source of contamination under model. In this case the model was prepared to give results for a soil level reception instruments web, based on what concentration level charts will be elaborated. The model is capable of showing information about the contamination concentration based in average time series (1 hour, 8 hours, 25 hours and 1 year). It has only being predicted maximum concentrations for 1 hour. The model ISC-3 takes into consideration some topographic effects, but in a limited manner. It wont be useful to use sophisticated models that take in consideration this effects if their is not also additional meteorological information. With the aim of predicting the maximum concentration in 1 hour a meteorological special file needed to be created which also had to be able to create a highly unstable atmosphere (ISC -3 first stability category), slow winds speed (2m/s) and wind direction from 1 (degree) to 360 (degree) North with 1 (degree) increasing. As was mentioned above it was estimated that this conditions would produced a worse scenario for the main stack emissions impact on the land receptors. The mix layer deepness was different for the preliminary models, this was to be able to determine the value for the worse of the cases. The mix layer is that atmospheric layer over the soil surface were the turbulent contaminant mix took place. Over the layer the atmosphere is stratified in a stable state and the turbulence is taken. In clear days, at sun rise the mix layer is shallow becoming deep as the day passes by. In the afternoon it is replaced by a inversion stable layer. The layer deepness is normally determine by information given by balloons or by using meteorological information of a higher altitude. This information was available during the execution of this project. It was found that the mix layer deepness for the main stack in unstable conditions, in the worse case scenario is in a range of 1 000 to 1300 m. The ISC - 3 automatically calculated the pluma de gasses raise under bad atmospheric conditions taking as a base the stack operative parameters. The pluma de gases raise was consistent with the visual information done at the smelter. The final pluma de gases raise was calculated approximately 1 200 m over the ground under bad meteorological conditions ( moderate wind and unstable atmosphere) The distance from the stack to the pluma de gases reaches a height of 1 700 meters. Under inversion stable conditions the ICS - 3 calculates a final pluma de gases of approximately 350 m to 400 m above soil level, this is obtained almost directly above the stack. Results and Discussion a) Main Stack In general, the dispersion model produces reasonable results in comparison with the environment monitoring data. This is shown in Table No. 5.3. The only exemption is the one at the Labor Union where the model underestimated in a significant manner the impacts. This location, however, is very close to the smelter operations and it is strongly impacted by the SO2 fugitive emissions coming from sources that were not addressed in this study. TABLE NO. 5.3 Maximum Concentration of 1 hour for SO2 - -------------------------------------------------------------------------------- Model Monitoring Data Monitoring Station Result 1995 1996 - -------------------------------------------------------------------------------- Hotel Inca 3 249 2 230 1 241 - -------------------------------------------------------------------------------- Cushurupampa 2 447 1 848 2 000 - -------------------------------------------------------------------------------- Labor Union 266 2 477 2 000 - -------------------------------------------------------------------------------- Casaracra 928 1 780 1 520 - -------------------------------------------------------------------------------- High levels of SO2 can be presented at points far away from the smelter. Graphic 5 shows the main stack impact ample magnitude. In some areas the short term SO2 concentrations that are superior to 1 000 mg/m3 are considered excessive. In Canada for example the maximum acceptable average level for one hour is 900 mg/m3 and in The United States the standard maximum concentration for 3 hours is 1 300 mg/m3 . The estimates that are indicated in Graphic 5 indicate that concentrations superior to 1000 mg/m3 could be present in a 9 kilometers radius at the smelter surroundings and under the worse meteorological conditions. The significant modifications to the main stack will produce a very small improvement in reducing the contaminants concentration at the ground level. This result points out the need to implement emission reduction strategies in addition to the changes to the main stack. The following modifications to the main stack were considered: o Double the flow that comes out of the stack by inducing dilution air at the base. o Reduce in a 30% the extreme diameter to double in this way the exit speed. o Increase the stack altitude from 167 meters from the ground level to 284 meters and 400 meters over the ground level. o Maintaining the actual stack altitude transporting it to 875 meters west from the present location were the soil has a higher elevation approximately 3 meters ( for example 4 050 meters above see level in contrast with 3 700 meters) The results of these simulations are summarized in Table No. 5.4 The less effective measure is transporting of the stack to the higher elevation place. The increase of the pluma de gasses will be too short. The estimated gas concentration in the worse case will only decrease by 20% at the Hotel Inca and Cushurupamapa Stations. These stations are approximately 5% higher than the Huanchan Station. This concentration level significantly increases at the Labor Union Station which is located at Mayupampa. This place receives a direct impact from the emitted gasses, it is not passed by the pluma de gases. TABLE No. 5.4 RESULTS OF THE SIMULATION FOR THE STACK MODIFICATION ALTERNATIVES Maximum Concentration of SO2 per hour - -------------------------------------------------------------------------------- Diameter Monitoring Station Actual Mass flow reduction at 284 m 400 m Moved Stack duplication Stack end Stack Stack Stack - -------------------------------------------------------------------------------- Hotel Inca 3 249 2 522 2 599 2 529 2 482 2 553 - -------------------------------------------------------------------------------- Cushurupampa 2 447 1 924 1 958 1 896 1 858 2 033 - -------------------------------------------------------------------------------- Sindicato de Obreros 266 97 215 83 28 4 113 - -------------------------------------------------------------------------------- Huanchan 3 249 2 522 2 599 2 529 2 483 3 405 - -------------------------------------------------------------------------------- Casaracra 928 741 743 717 700 885 - -------------------------------------------------------------------------------- The other proposed modifications produce a 20% concentration reduction for 1 hour maximum. Considering all the changes to the Stack this reduction is not significant. Furthermore, the concentration level prognosticated continues maintaining a level much higher than the one established (1 000 mg/m3). The Graphics 6 and 7 show SO2 concentration levels for one hour maximum for when the main stack is moved and for its extreme reduction in 30%. These levels can be compared with the ones in Graphic 5 to gain a general idea of the effects that the modifications at the main stack will produce. The main stack transportation to a higher place (Graphic 6) produces some reduction around the smelter, but still the concentrations are higher than 1000 mg /m3 in a ration of 9 kilometers. The stack's diameter reduction by 30% produces a general reduction of the concentration at ground levels as a result that 1000 mg/m3 concentration extends only to 7 kilometers. b) Fugitive Emissions Even though this study had the objective of examining the main stack gas emissions, at the beginning of the study it was evident that the fugitive emissions were an important source of contamination and of the low quality of the La Oroya smelters air. The mathematical model E. regarding air dispersion indicates that the main stack emissions do not affect in a significant manner the monitoring station located at the Labor Union, which is located 800 meters from the smelter. However from the results at the 5 monitoring stations this one presents the second highest SO2 concentration in one hour for the 1995 year, having a range of 2 477 mg/m3. The results suggest that the contamination source in this case comes from the fugitive gases. Clearly, it can be observed that the Copper Converters and the Coke Plant are the principal sources of contamination, although these are only two of the number of emission sources that are at the smelter. The corresponding stack heights for the most part are producing very little fumigation effect over the nearby buildings. The local meteorological information indicates that clam winds are present 40% of the time, which means that the fugitive emissions tend to remain at the surrounding areas. An additional study of the emissions sources is required to be able to evaluate the contamination local impact. A detailed analysis of the fugitive emissions is necessary to identify the sources, take measures and develop contamination control appropriate strategies. Conclusions and Recommendations o It requires a significant reduction of the gas emission as well as the SO2 concentration levels in all the monitoring points located inside the smelter with the objective of complying with the maximum permissible limits that the Peruvian law and the World Bank establishes. It will be necessary to implement strategies that are directed to reduce the emission volumes to be able to reach the established standards. The modification that can be done at the main stack will only have an impact on the air quality standards, but not on the contaminants emission standards. o Due to the complex topography and to the limited meteorological information only approximate predictions for the hourly contamination emitted by the main stack are possible. The simulations accomplished related to the main stack modifications indicate that a small improvement of the contamination levels will be obtained. This result re-enforces the need to put into practice emission reduction strategies probably in combination with the main stack modification. o The implementation of a Supplementary Control System will allow the smelter to use in line meteorological information, as well as some diverse models that will allow prediction of local atmospheric conditions that could result in excessive contamination levels. It will also be possible to predict potential sources of significant levels of contaminants (if they come from the main stack or from fugitive emissions) which will depend on the climate conditions. Appropriate measures could be taken to reduce some emissions until more favorable climate conditions occur. o A detailed evaluation of the smelter contamination sources must be done and the use of adequate control technology such as filters ( Bag House) and scrubers must be adopted. Many of the emission sources could be connected through the main stack ducts. A dispersion model and the use of a scale model of the Metallurgical Complex in the wind tunnel will be extremely useful to identify the emission sources, prioritize intervention activities and adequate control. The wind tunnel allows simulation of the complex and the wind behavior topography as well as the gaseous emissions. 5.6 Public Heath (Sewage and Garbage) PROJECT : Sewage Water and La Oroya Garabage Disposal 1. Introduction The sewage water treatment and the garbage disposal at the CENTROMIN housing areas in La Oroya is a service that is assumed by the Company. This service is for a population of 18 000 people that are located around the Yauli and Mantaro rivers. It is made in a similar manner as the rest of the region, which is not in accordance with the health norms and requirements, and does not take in consideration environmental issues to be considered by these services. For this reason the Environmental Program for La Oroya considered this study. The project was developed by the firm AQUA PLAN INGENIEROS SCRL up to the engineering level, the same that was finished in May 1995. The work exceeds what will be CENTROMIN SA investment responsibility. The privatization plan only considers housing installations at the Mantaro river shore. In such situation this report only refers to a future responsibility. 2. Present Situation Analysis The Centromin Housing sewage system along the Mantaro river constitutes a web that allows to connect the totality of the sewage waters and escorrentia. It is in a good condition, but it discharges directly to the Mantaro river. This discharge with no treatment is one of the river's contaminants. In relation to the garbage pick up it is accomplished by a compactor truck, which does not have the necessary capacity to pick up 9 additional kilometers up to the pouring point. At the garbage disposal area, the garbage is set with no sanitary filling technique, this situation gets complicated because the deposit is located at the left margin of the river close to the water. It constitutes an additional point of contamination. It is necessary to correct the systems technical deficiencies, installing sewage water treatment plants and the construction of a sanitary fill that will guaranty an environmental cleaning. 3. Project Objective The development of engineering studies up to the detail level, that will allow treatment of the sewage waters and the Centromin housing garbage disposal to prevent contamination of the Mantaro river and comply with the requirements established by the government. 4. Project Justification This project of environmental cleaning is urgent due to the impoverishment of the basic services for the population in general and in particular due to the sewage and garbage problems of this production unit. The solution of this problem is framed by the environmental problem with the objective of obtaining a sustainable development having an ecological equilibrium among men, nature and production. 5. Project Description After the solution alternatives been analyzed, from a technical - economical point of view for the sewage water case, a treatment alternative will be 2 mud plants activated using the aereacion extended method. For the garbage disposal the sanitary fill solution will be adopted using the trinchera method, which will be in accordance to the Health Ministry (DIGESA) - Characteristics a) Sewage Water Treatment For this treatment 2 plants have been considered. They will be located along the Mantaro river, one at the Chulec zone and the other one in front of the Hotel Inca zone (Sudete zone) The project considers also intersection lines, conduction line and the collection of the sewage waters towards the treatment plant. Due to the topographic characteristics of the area it will be necessary to install pumping station. After the treatment, which uses biological processes, a discharge flow of 30 ppm of BOD and 40 ppm of suspended solids will be obtained. o Chulec Plant The installation will have a treatment capacity of 12.5 liters / seg. Located at the right margin of the Mantaro river at the area named Parque Lavaropa. Its area of influnce are the sectors of: Mayupampa, Chupamapa, Tortilla and Chulec. The treatment considers the following processes: Taking the Sand Out: In this treatment the sewage waters are pushed by a pumping station and conducted to a sand remover channel which is made of concrete. At this point using the differential segmentation principle, sedimentation of the sand will be produced and the organic solids will be in suspension which will be crushed. Aeration: In this treatment the organic material is directed by aerobic microorganisms that are contained at the re circulated mud. This process is done in a concrete tank of 12.0m x 24.0m x 4.0 m with two aerators (2HP) to transfer to the liquid mass 5.80 lbs/hr of oxygen. Decant Process: It has the aim of separating the solids from the liquids. The tank to be used will be of concrete 16.60m by 3.00 m with retention period of 4 hours and a maximum surface rate of 30 gal/p2/hr. It will have a mechanical cleaning system. Drying: This process will be done in 2 concrete drying beds of 4.00m by 1.00 meters were the mud excess will be dried in a accelerated manner by filters, the excess of liquid will be returned by pumping. Control: This activity is done in a laboratory that has an area of 6.00 m by 6.00 where the BDO, SS, pH, Dissolve Oxygen, SVI (volatile solids) and NMP ( number of fecal colliforms) are determined on daily basis. o Sudete Plant This installation has a treatment capacity of 18.0 liters / seg. Located at the recreational area of Sudete in front Inca Hotel. Its area of influence is: Amachay, Hidro, Railway, hotels and Sudete. The treatment considers the same processes as the one indicated for the Chulec Plant with the following Physical Characteristics: Sand Taking: In a concrete channel of 13.60 meters long with a manual cleaning system, its measuring system is Parshall type and it has a solid crusher. Aeration: In a concrete tank that has a trapezoid shape with an area of 390 m2 and a deepness of 4.60 m, with 2 aerators (3.5 HP) to transfer to the liquid mass of 6.80 pounds and hour of oxygen. Decant Process: Having two concrete twin tanks of 24,00 m by 3,80 m by 400 meters each one, with a retention period of 4 hours and a surface cup of 30 gallons / p2 / hour maximum. Each one will have a mechanical mud cleaning system. The mud obtained will be pumped to the aereacion tank. Drying: This process does not take place at this plant. Control: Activity that is done at a laboratory that has an area of 6:00 meters by 6.00 meters, where values for BDO, SS, pH, Dissolved Oxygen, SVI (volatile solids) and NMO ( probable number of fecal collifroms) are determine daily. o Pumping Stations: Due to topographic stations, the system will have 3 pumping stations; two for Chulec and one for Sudete. b) Garbage Disposal The solution selected corresponds to one of a residues final disposal plant, that uses the Sanitary Filling method. The plant is located at the Cochabamba zone at the area that the disposal is made today, having a useful area of 2.5 hectares. o Cells It will have modules conformed by cells Trichera type of 5.00 meters wide and 3.00 meters height with variable lengths according to the area conformation. This cells will be waterproof at the bottom with a geo textile and a geo membrane Gundle. The garbage setting will be done in layers of 0.20 to 0.30 meters spread and compacted by a tractor; when this is accomplished it will be covered by a soil layer of 0.40 meters that will be also compacted. It has been also considered a stack ventilation for the gasses, drainage and liquid entrapment as well as septic tanks. o Complementary Work It is been projected to build garages, control booth, offices and a fence. o Equipment Two compacting trucks that will collect the garbage (16 cubic yards) Two Caterpillar D4 and D6 Tank car with a hose and aspersion device. Pump for the rain water. - Investment Budget The treatment project for the sewage water and the garbage disposal will require the execution of the following items and the amount required is also included.

In this way developing the basis for environmental control. This action even though is at an engineering level has deserved the attention of government offices such as the President Ministry. The solution is being taken into consideration for cleaning projects for the entire City of La Oroya. - Economic Analysis The project characteristics do not allow to define its profitability, but it can be pointed out its indirect retribution which is a better living for the City of La Oroya., diminution of contamination at the river basin and diminution of the epidemics. - Conclusions and Recommendations The project developed allows to solve the problems of treating the sewage waters and garbage generated at the housing area that belong to the company. The project has been modeled to be executed in stages, which can start independently. It has also been considered, the situation of a future privatization, in which case the housing at the Mantaro river will probably remain under the company's administration. It will be also necessary to initiate the pertinent works, arrangements with the local authorities and government offices 5.7 Social - Economic Resources Impact Control 5.7.1 Mitigation Measures Plan, Contingencies Implementation Plan Social - Economic Mitigation Measures a) Stopping other uses for land and adjacent areas. o Give an adequate treatment to the Fumes and the Populated Adjacent Areas and to the Abandon Waste Deposits. o Improve the use of space and assure the well being of the population and accelerate the demolition of the obsolete houses that are very much deteriorated as the ones that are at the: Club Peruano, Tras Estacion, Railway, Calaminas, Plomos.

In this sense PAMA looks to define the basic criteria to be considered for the adequate and opportune treatment in case of accidents, leaks, explosions, fires, etc. The programmed activities must consider the company's personnel training for using the emergency equipment. This type of program must be addressed not only to workers but also to people at the nearby communities in La Oroya ratio of action. 5.8.2. Objectives and Scopes The principal purpose of a contingency plan is to protect human life, material goods and the natural ecosystem life in case of an emergency caused by an extreme situation, being the fundamental requisite to be prepared for an immediate response and solve the incident. The contingency plan must include the following: o A list of people and offices that must be alerted and informed immediately in case of an emergency. o The procedures to evaluate people risks when located in the emergency area neighborhood . o A list of actions, with a priority order that must be accomplished in case of an emergency o The authority designation, the identification of the line of command and the designation of the qualified personnel for those specific endeavors. o Communications webs that will assure the coordination of efforts and the efficient responses. o A reference material (maps, indicting the sensible areas or the ones that have high probability of fracture, technical equipment to use in emergency cases) and other technical information that could be of help for the people responsible of the actions, and. o An inventory of the equipment type and material available to respond to an emergency, including a location map. 5.8.3 Organization The organization designed in the present contingency plan will be in charge of coordinating the human and physical resources to be activated in time of environmental emergencies. A Security Environmental Committee will be established, which will coordinate the principal actions and take the basic decisions to follow during and after the emergency. To comply with this objective the committee must be provided with all the communications systems and facilities to control the emergency. The personnel that must be on this committee are the following: o General Manager o General Superintendent o Safety Superintendent o Chief of the environmental area o Doctor in charge of occupational health o A workers representative Brigades are established to confront environmental emergencies, formed by groups of people in charge of going to the incident place. Timely intervention could save many lives, equipment and infrastructure. It is the implementation of permanent rescue crews composed at least of 10 duly trained people. It is necessary to take into consideration that these brigades must have medical personnel support as well as the safety personnel to give the facilities to the people that help mitigate the incidents. 5.8.4 Training There must be an annual training plan "The safety brigades" will be trained, they must renew the instruction in periods not longer than three months (article 42 of the Supreme Decree No 023-92-EM) This program must include the following stages: o The personnel training in maintaining, operating, transporting, using and managing the emergency use equipment. o The simulation of different type of emergencies, taking in consideration the places were they could occur, the actions and the physical resources to use. Manuals for information should be prepared about the sequence in the actions to take during the simulations and the practice evaluations methodology o The classification categories of the material spillage, tailings, fuel, etc., determining the frequency and the risks involved; and, o The knowledge of how to use the first aid equipment, alarms and procedures for the safety equipment use. Having well trained personnel and surveillance personnel is highly important in case of emergency. 5.8.5 Information Management and Communications The necessary actions must be establish to cover the following aspects: o n Appoint the responsible area for communicating the situation to the General Office of Environmental Affairs at the Mining and Energy Ministry. (DGAA.MEM) . The communication must be made 48 hours after the incident occurs. o Define the area that will prepare the preliminary report that will be sent to the DGAA - MEM. Also a format will be prepared that will include the type of incident, place, date and time, the apparent cause, human and material losses, the actions taken to mitigate the emergency as well as the mitigation plan and rehabilitation of the affected area. o Guaranty that the required information about the climatic conditions ( wind direction and speed, temperature and flows) will be handled in an adequate and timely way. o Implement the alarm system against fire, independently from the communication system. 5.8.6 Resources a) Transportation La Oroya must have vehicles available capable of entering the most difficult terrain were a mining operation exists. The number of vehicles will be related with the extension and distribution of the operations. b) Communications Web The different installations must have permanent communication system connected with the General Superintendent and the Safety Chief, either by radio or by telephone. This should by time extended to the public and private entities of the locality. c) Alarm System The alarm system at the principal production unit installations consists of a siren. It must be appropriately located to alert the personnel and the local population that could be affected with the incident. d) First Aid Equipment Beds, stretchers, and first aid supplies. e) Emergency Material and Equipment PQS Extinguishers, safety hamlets, safety belts, leather gloves, tools and flour protein foam to extinguish fire in liquids. 5.8.7 Emergency Specific Cases The following are some of the incidents that can occur and the contingency plan for such cases. a) Process Leaks and Spills (reagents, fluids and tailings) This type of incidents can occur at any moment, having a negative impact on the environment. It is necessary to take action on time to reduce occurrences and the consequence of this type of emergencies. Inspection must be done regularly at the different conduction and supplying devices. The following actions must be included in a contingency plan in case of reagents and or fluid spill : o A map of the place, indicating were the chemical products are stored. As well as the fluids conduction and distribution lines ( the flow diagram should be available at different locations) o Make sure that the chemical products are adequately stored, with fences to preclude contamination of the area. o All the products must have toxicological information and cleaning procedures in case of spillage. o Availability of secondary containers for reagents and process fluids. b) Fuel, Oil, Solvents and liquid hydrocarbons Spillage. When this type of emergency occurs, the operator must try to isolate the damaged tank with the objective of reducing the spill affected areas. Then proceed to remove the contaminated soil in accordance to the management and residue disposal program prepared by the company. In addition to the steps mentioned above, the following steps must be included in a contingency plan for oil spillage. o Information that will identify the spillage migration scheme under different climate conditions. o Contention Systems for all the fuel tanks, and Have secondary containers for hydrocarbon spillages. c) Fires This type of emergency could happen due to a mechanical break down of the equipment ( spakles, fuel leaks) handling, or unsure acts that will produce the conjunction of these three elements : flammable fluids, (combustion vapors) oxygen and heat. This contingency can generate equipment deterioration and the mining operations interruption as well as human life and environment risk. In this same manner a fast action is required from the emergency brigade. The emergency will be controlled in the following manner: o The personnel that will fin out the emergency situation will close the fuel supplying valves. The fire will be fought immediately with the available resources ( dry dust extinguishers or CO2) which will be at the places indicated in the evacuation map. This action will be done until the fire is controlled. Finally the incident will be reported to the Environmental Safety Committee. o If the fire con not be controlled the machines will be turn off. o The plugs that isolate the electric installations will be set on. o Give immediate notice to the fire brigade. If the brigade is too far away, the personnel that is in the site will take the corresponding action until the brigade arrival. o The personnel that is not participating in the fire control because was not trained for this must evacuate the area. o Notice should be given to the city fire men and the civil defense chief. The notice should indicate the type, magnitude and time that the fire start. o To evacuate injured people to an area were they can get medical attention. e) Seismic Occurrences The personnel must stop their work and evacuate the area immediately to prevent accidents. If it is necessary depending upon the intensity of the earthquake the fuel supply will be closed and the equipment shut off, evacuating the installations towards an empty area. The injured personnel must receive attention, after the disaster the material damages will be evaluated. The committee of environmental safety will give instructions. VI CLOSING PLAN STUDY FOR THE CLOSING PLAN FOR LA OROYA METALLURGICAL COMPLEX 1. Introduction In the future La Oroya Metallurgical Complex must close its operations. This future situation must be contemplated, analyzed and studied with solution programs that will guaranty at the ending of the operations a control of the contaminant bodies, the recovery of the affected areas and the restoration of the areas to an acceptable level for future use. For these reasons the closing plan program was considered in this study. The project is being developed by the Canadian Firm ADI INTERNATIONAL INC up to a basic engineering level. 2. Present Situation Analysis The age of the installations, the quantity of the buildings and process, mechanical, electric and control equipment, the diversity of the metallurgical processes for smelting and refining the 17 metals there are among product and sub products gives origin to a 55 hectares operation. Area that for its most part have been affected by the contamination produced in the processes. This environmental contamination with the generation of liquids, solids and gasses that over pass the permissible limits has damage the environmental conditions, specially with respect to the soils deterioration, the partial disappearance of the biotic environment and the water corps damage. It is a industrial zone scenario of high congestion that needs to be revert the condition that it had before the operation started. 3. Project Objective Develop the engineering studies to a basic level that will allow to accomplish the closing plan in accordance with the parameters set out by PAMA. This parameters consider the removal of the existent installations, the elimination of the contamination sources, recovery of the soil and the remediation works until the area has its initial characteristics. 4. Project Justification Although this project does not seem one of immediate execution, it one that can not be delayed, since it constitutes the most important element to consider, not only at the operations ending but also in the eventuality of partial closings. In the other hand the stages closing plan such as the demolition , dismantle and restoration works to acceptable environmental levels and other inherent to the case will permit a rational use of the resources, since a considerable amount of time and money is required for all these. 5. Project Description The project at this basic engineering level develops a basic stage of planning, setting diverse activities that must be executed until a master plan is done for all the closing aspects. - Characteristics Basic Plan Stage This stage has considered diverse activities that must be developed on blocks: o Closing Decision o Inventory Culmination o Establishment of Environmental Control o Dismantling and removal of useful equipment o Demolition o Site investigations o Site Recoveries Each of this blocks diversifies in series of activities that will constitute at the end the Closing Master Plan. Preliminary Experiments There have been executed some surface experiment covering the total LA OROYA CENTROMIN installations area with the aim of gathering information on the S, Cd and Pb contents in the soil and the existent plants. Additionally inspections will be made to have basic hydric and geo technical information. With the sample results the research work to be developed in the detail engineering will be defined. - Investment Budget The investment budget for a total closing of the complex is a follows: - ------------------------------------------------------------------------------ DESCRIPTION AMOUNT US $ - ------------------------------------------------------------------------------ 1.0 Equipment dismantle 15 000 000 - ------------------------------------------------------------------------------ 2.0 Metallic Structures dismantle 19 000 000 - ------------------------------------------------------------------------------ 3.0 Buildings Demolition 5 000 000 - ------------------------------------------------------------------------------ 4.0 Investigation and area fixing 5 500 000 - ------------------------------------------------------------------------------ 5.0 Equipment and building recoverings (22 000 000) - ------------------------------------------------------------------------------ SUB TOTAL 22 000 000 - ------------------------------------------------------------------------------ CONTINGENCIES 2 000 000 - ------------------------------------------------------------------------------ TOTAL 24 000 000 - ------------------------------------------------------------------------------ - Execution Schedule The execution schedule requires 70 months following this details: - -------------------------------------------------------------------------------- ACTIVITY TIME (MONTHS) - -------------------------------------------------------------------------------- 1.0 Inventory 1 - -------------------------------------------------------------------------------- 2.0 Environmental Control Establishment 3 - -------------------------------------------------------------------------------- 3.0 Dismantling of equipment and removal of useful equipment 9 - -------------------------------------------------------------------------------- 4.0 Demolition 9 - -------------------------------------------------------------------------------- 5.0 Site Investigations 12 - -------------------------------------------------------------------------------- 6.0 Site Recovery 36 - -------------------------------------------------------------------------------- TOTAL 70 - -------------------------------------------------------------------------------- 6. Mitigation Proposal If the complex closing is implemented, an immediate contaminant reduction will be produced and a high proportion of the contaminants discharged into the atmosphere. As the closing activities master plan enters into application the contamination will be reaching inferior levels that will reach the permissible limits when the process is concluded. 7. Economic Analysis The project characteristics which is not involved on the production process does not allow to define the type of profitability that can be quantified in economical indexes, but it can be pointed out that the environment remediation will contribute to improve the life conditions not only at La Oroya but also the Mantaro river and the Mantaro valley. 8. Conclusions and Recommendations The developed project will allow to cover PAMA requirements The project will allow to have a basic planning that can be used for a total or a partial closing. Contingency plans are considered in case of natural catastrophes that can happen in the future such as floods and earthquakes. Before initiating the pertinent works in case of closing, it will be necessary to make the respective coordination with the local authorities and the government entities. VII EMISSION AND EFFLUENTS MONITORING PLAN 7.1 Liquid Effluents emissions if the Metallurgic Complex Regarding the policies defined by Centromin Peru S.A. with respect to the Environmental Contamination Control diverse mitigation measures undertaken with important investments must be pointed. With respect with the liquid effluents it has been planned to continue with the sampling at the collectors discharge that were qualified has contaminants after they were processed and the results analyzed by the statistics results from the EVAP (tabla 7.1) Due to the water quality, the monitoring will be done at 9 monitoring stations (five in the Mantaro River, three at the Yauli river and one at the Tishgo river). 7.2 Gaseous Emissions at the Metallurgical Complex Concerning the gaseous emissions monitoring and the air quality, it has been clearly defined and put into action. The environmental problems have been characterized as a consequence of the gases, it is necessary to implement mitigation measures. The monitoring data obtained at the metallurgic complex indicates that the air quality as well as the gaseous emissions have been exceeding the permissible limits. The company has planned to continue with the monitoring program related to the emission sources at the strategic points indicated in table 7.2. To determine the air quality CENTROMIN will continue the monitoring 5 stations (Table 7.2) and will improve the sampling system with new equipment when necessary. CENTROMIN treats more than a thousand tons a day of concentrate, hence it's considering the installation of a meteorological station at the place stated in the Gaseous Emission Protocol and Quality Air, where the wind parameters (speed and direction), temperature, precipitation, evaporation, relative humidity are considered with frequency and ideal equipment.
