3.4 Retained Liabilities. Purchaser shall not assume or be obligated to pay, perform or otherwise discharge any Liabilities of Sellers, other than those that are expressly assumed by Purchaser hereunder as Assumed Liabilities (collectively, the “Retained Liabilities”). Without limiting the generality of the foregoing, the Retained Liabilities include the following Liabilities of Sellers:

(h) all Liabilities for any natural resource damages at any Non-Target Property that result from migrations or Releases of Hazardous Materials from Real Property that occurred prior to the Closing Date and did not continue thereafter.

3.5 Contract Designation Rights.

(a) Contracts that were entered into prior to the filing of the Bankruptcy Cases to which ASARCO is a party that, as of the date of this Agreement, have not been assumed by Sellers and are to be assigned to Purchaser (the “Assumption-Pending Pre-Petition Contracts”) are identified in Section 3.5(a) of the Seller Disclosure Schedule and all such contracts shall be assumed and assigned hereunder. Purchaser shall timely deliver to Sellers such information or documentation relating to “adequate assurance of future performance” as shall be reasonably required in connection with the assumption and assignment of such Contracts pursuant to the Plan.

(b) At or prior to the Closing, to the extent not previously paid, Sellers shall pay any and all Cure Claims with respect to all Assumption-Pending Pre-Petition Contracts; provided, that any Unpaid Cure Claims Amounts shall be subject to Section 3.5(d).

(c) Nothing in this Agreement shall be construed as an attempt by any Seller to assign any Contract to the extent that such Contract is not assignable without the necessary notice to or consent of the other party or parties thereto, and such notice to or consent of such other party has not been given or received, as applicable. Purchaser acknowledges that no adjustment to the Purchase Price shall be made for any such Contracts that are not assigned and that Purchaser shall have no claim against Sellers or any other Person in respect of such unassigned Contracts. Notwithstanding the absence at Closing of one or more required consents to the assignment of a Contract that is intended to be an Assumed Contract, following the Closing at such time as consent has been obtained, or any requisite notice has been made or delivered, as applicable, the related Contract shall be assigned to Purchaser automatically without any other conveyance or other action by Purchaser. From and after the Closing, pending receipt or in the absence of any such consent, Sellers will hold the benefit of such Contract that is intended to be an Assumed Contract for Purchaser and subcontract to Purchaser all rights and obligations of Sellers thereunder to the extent allowed by such Contract. As between Sellers and Purchaser, Purchaser will be deemed to have fully assumed Sellers’ performance obligations for any such Contract that is intended to be an Assumed Contract at Closing in accordance with this Agreement.

(d) At the Closing, ASARCO shall deliver to Purchaser a statement of any Unpaid Cure Claims Amount (and the Contract(s) corresponding thereto), including a calculation

thereof. Purchaser shall be permitted (but not required), within 30 days after receipt of such statement, to pay any Unpaid Cure Claims Amount, and within 10 days after any such payment, Purchaser shall provide a written notice to ASARCO of such payment (and the Contract(s) corresponding thereto). To the extent Purchaser pays any Unpaid Cure Claims Amount pursuant to this Section 3.5(d), Sellers shall, within 10 days of receipt of notice from Purchaser delivered in accordance with this Section 3.5(d), reimburse Purchaser in the amount of such payment; provided that, the Plan Confirmation Order shall provide that, as between the Sellers and the counterparty of the underlying Contract, (i) neither the payment nor the reimbursement of a disputed Unpaid Cure Claims Amount shall constitute a waiver, admission or estoppel in respect of any claims or defenses that ASARCO may have related to such Unpaid Cure Claims Amount or the underlying Contract and (ii) ASARCO’s right to object, assert any counterclaim or exercise any setoff or other rights in connection with such Unpaid Cure Claims Amount or the underlying Contract shall be preserved regardless of any such payment or reimbursement; provided, however, that failure of the Plan Confirmation Order to so provide shall not relieve the Sellers of their payment obligations as set forth in this Section 3.5(d).

3.6 Silver Bell. The parties acknowledge that pursuant to the Silver Bell LLC Agreement, the sale, assignment and transfer by ARSB of its Silver Bell Interests is subject to the consent of the other members of Silver Bell. If such consent is not obtained prior to Closing, then (i) the Silver Bell Interests and Sellers’ right in and to the Silver Bell LLC Agreement will each be an Excluded Asset and the shares of capital stock of ARSB will be a Purchased Asset and (ii) references in Section 7.5 to Silver Bell Interests will be deemed to refer to the capital stock of ARSB.

ARTICLE IV
PURCHASE PRICE AND PAYMENT

4.1 Purchase Price. The total consideration paid by Purchaser to Sellers in consideration of the sale, conveyance, transfer, assignment and delivery of the Purchased Assets is (i) an amount equal to: (A) $1,100,000,000.00 (the “Closing Payment”), plus (B) the Purchaser Promissory Note (collectively, the “Purchase Price”) and (ii) the assumption by Purchaser of the Assumed Liabilities.

4.2 Deposit. Purchaser shall make available to ASARCO funds in the aggregate amount of $125,000,000.00 (the “Deposit”) as follows:

(a) Prior to the execution of this Agreement, Purchaser posted a letter of credit (the “First L/C”) attached as Exhibit O-1 hereto issued in favor of ASARCO by ABN AMRO Bank N.V., Chicago in the amount of $50,000,000.00. After the entry of the Sterlite Agreed Order by the Bankruptcy Court, Purchaser may amend the First L/C solely to add the following to Annex A of the First L/C: “Funds under the Letter of Credit are payable in accordance with the terms set forth in Section 4.2 of that certain Settlement and Purchase and Sale Agreement, dated as of February ___, 2009, among, inter alia, the Beneficiary and the Account Party.” Purchaser, with the prior written consent of Sellers (which consent shall not be unreasonably withheld), shall have the right to exchange the First L/C for a replacement letter of credit issued by a Qualified Bank in substantially the same form as the First L/C and on terms and conditions reasonably satisfactory to Sellers.

(b) Simultaneously with the execution of this Agreement, Purchaser has posted a second letter of credit (the “Second L/C”) attached as Exhibit O-2 hereto issued in favor of ASARCO by ABN AMRO Bank N.V., Chicago in the amount of $50,000,000.00. Purchaser, with the prior written consent of Sellers (which consent shall not be unreasonably withheld), shall have the right to exchange the Second L/C for a replacement letter of credit issued by a Qualified Bank in substantially the same form as the Second L/C and on terms and conditions reasonably satisfactory to Sellers.

(c) As promptly as practicable following (but not later than 5:00 p.m., Dallas, Texas time, on the third Business Day following) the Disclosure Statement Approval Date, Purchaser will post a third letter of credit (the “Third L/C”) in the form of Exhibit O-3 hereto issued in favor of ASARCO by a Qualified Bank in the amount of $25,000,000.00 and ASARCO shall have received such originally executed Third L/C enforceable against the issuer thereof. The First L/C, the Second L/C and the Third L/C are collectively referred to herein as the “Letters of Credit.”

(d) Subject to Section 4.2(h), in anticipation of Closing and upon the agreement of the parties, ASARCO shall draw on the Letters of Credit. All cash received by ASARCO (in immediately available funds in an account designated by ASARCO) prior to or on the Closing Date pursuant to such draw shall be credited against the Closing Payment at Closing and retained by Sellers as a component of the Purchase Price. Alternatively, at least three Business Days prior to the Closing Date, Purchaser may deliver a written notice to ASARCO instructing ASARCO that it shall deliver the full amount of the Closing Payment to ASARCO pursuant to Section 5.3(a) at Closing. In such case, at Closing, upon receipt of the Closing Payment pursuant to Section 5.3(a), ASARCO shall deliver to Purchaser each of the Letters of Credit for return to the issuer thereof for cancellation (or any cash drawn and received pursuant to Section 4.2(h)).

(e) Immediately following the termination of this Agreement due to a material breach by Purchaser or Guarantor of any of their respective representations, warranties or covenants or other agreements hereunder (a “Purchaser Breach”), Sellers shall (i) be entitled to receive from Purchaser and retain the Deposit and (ii) be entitled to draw upon all Letters of Credit at anytime thereafter to obtain the Deposit and the receipt by Sellers of immediately available funds in an account designated by ASARCO in an amount equal to the Deposit pursuant to such draw (or any draw pursuant to Section 4.2(h)) shall satisfy Purchaser’s payment obligation in clause (i); provided, that only $100,000,000.00 shall be paid to and may be drawn by Sellers if such termination occurs prior to the Disclosure Statement Approval Date.

(f) Immediately following the termination of this Agreement for any reason other than (i) a Purchaser Breach or (ii) by Purchaser pursuant to Section 13.1(j) upon the occurrence of a Manipulative Breach, Sellers shall (x) be entitled to receive from Purchaser and retain $50,000,000.00, (y) be entitled to draw upon any outstanding Letter of Credit at anytime thereafter to obtain such funds and the receipt by Sellers of immediately available funds in an account designated by ASARCO in an amount equal to $50,000,000.00 pursuant to such draw (or any draws pursuant to Section 4.2(h)) shall satisfy Purchaser’s payment obligation in clause (x)) and (z) as promptly as practicable, and in any event within 10 Business Days, return the Second L/C and (if posted) the Third L/C to the issuer thereof for cancellation (or any cash

drawn (and received) pursuant to Section 4.2(h) in excess of $50,000,000.00; provided, that if (and only if) a Release Condition occurs following the termination of this Agreement, as promptly as practicable, and in any event within 10 Business Days, following the occurrence of such Release Condition, ASARCO shall either (1) return the First L/C to the issuer thereof for cancellation or (2) if Sellers have already drawn on the First L/C, including pursuant to Section 4.2(h), (and received $50,000,000.00 in respect of such draw), Sellers shall deliver the amount of $50,000,000.00 to Purchaser and such payment shall be made by wire transfer of immediately available funds to an account designated by Purchaser.

(g) As promptly as practicable, and in any event within 10 Business Days, following the termination of this Agreement by Purchaser pursuant to Section 13.1(j) due to a Manipulative Breach, ASARCO shall return the Letters of Credit to the issuer thereof for cancellation (or any cash drawn and received pursuant to Section 4.2(h)).

(h) At all times the remaining period until the stated expiry of each Letter of Credit shall be at least 30 days. From time to time, Purchaser shall cause the Letters of Credit to be amended to extend the expiry dates thereunder (without any other modifications thereto) in order to comply with the immediately preceding sentence. If at any time the remaining period until the stated expiry of any Letter of Credit is less than 30 days, ASARCO shall be entitled to draw upon such Letter of Credit at anytime thereafter; provided, however, that if the parties mutually agree that the Closing is reasonably likely to occur during such 30 day period, then ASARCO shall not draw upon such Letter of Credit until the remaining period until the stated expiry of such Letter of Credit is 20 days or less and all cash received by ASARCO (in immediately available funds in an account designated by ASARCO) prior to or on the Closing Date pursuant to such draw shall be credited against the Closing Payment at Closing and retained by Sellers as a component of the Purchase Price; provided, further, that, notwithstanding anything to the contrary contained herein, any cash drawn and received pursuant to this Section 4.2(h) that is to be returned to Purchaser pursuant to any other provision of this Section 4.2 shall be returned to Purchaser immediately.

(i) Notwithstanding anything to the contrary contained herein, except pursuant to Section 4.2(d), any draw upon any of the Letters of Credit shall be approved by the Bankruptcy Court as an act outside the ordinary course of business under 11 U.S.C. § 363(b)(1). For clarification, Sellers’ right to draw upon a Letter of Credit is not conditioned upon any other finding by the Bankruptcy Court; provided, however, that such Bankruptcy Court approval shall not be required for any draw upon the First L/C prior to the entry of the Sterlite Agreed Order by the Bankruptcy Court.

4.3 Purchase Price Adjustment.

(a) No later than 45 days after the Closing Date, Sellers shall deliver to Purchaser a statement (the “Closing Accounts Statement”) prepared in accordance with the illustration set forth in Exhibit E setting forth (i) the Included Receivables, the Included Payables and the Inventory Amount, each calculated as of the Closing Date, and (ii) a calculation of the Closing Accounts Amount.

(b) From and after the Closing Date until the delivery of the Closing Accounts Statement, Purchaser shall give Sellers reasonable access during normal business hours and upon reasonable notice to the Books and Records, the accounting and other appropriate personnel and the independent accountants of the Business in order to enable Sellers to prepare the Closing Accounts Statement and to calculate the Closing Accounts Amount.

(c) On the date that a binding determination of the Closing Accounts Amount has been made in accordance with Section 4.4, the aggregate principal amount of the Purchaser Promissory Note shall automatically be (i) increased by the Adjustment Amount if the Closing Accounts Amount is greater than the Agreed Working Capital or (ii) decreased by the Adjustment Amount if the Closing Accounts Amount is less than the Agreed Working Capital, in each case without any action on the part of Purchaser or Sellers.

4.4 Dispute Resolution.

(a) Purchaser shall be entitled to dispute the calculation of the Closing Accounts Amount set forth in the Closing Accounts Statement if, but only if, Purchaser delivers a written notice (an “Objection Notice”) to Sellers within 30 days after receipt of the Closing Accounts Statement in which Purchaser objects to the calculation by Sellers of the Closing Accounts Amount and provides a reasonably detailed description of each item to which Purchaser objects, the amount Purchaser believes is correct with respect to each such item and the basis therefor (the date upon which Purchaser delivers an Objection Notice to Sellers being hereinafter referred to as the “Objection Date”). If no Objection Notice is delivered within the time required in this Section 4.4(a), the Closing Accounts Statement delivered by Sellers and the calculation of the Closing Accounts Amount set forth therein shall be final and binding on each of the parties.

(b) If Purchaser delivers an Objection Notice to Sellers within the time period specified in paragraph (a) above, Purchaser and Sellers shall attempt in good faith to agree upon the Closing Accounts Amount during the period commencing on the Objection Date and ending 10 days thereafter (the “Negotiation Period”).

(c) If Purchaser and Sellers agree in writing prior to the expiration of the Negotiation Period on the Closing Accounts Amount, whether such amount is the same as or different from the amount calculated based upon the Closing Accounts Statement, the amount agreed to in writing shall be the Closing Accounts Amount for all purposes hereunder.

(d) If Purchaser and Sellers do not agree in writing prior to the expiration of the Negotiation Period on the Closing Accounts Amount, the items in dispute (but no other

matters) shall be submitted to KPMG LLP or such other firm of independent public accountants as may be mutually agreed between Purchaser and Sellers (in either case, the “Final Arbiter”). The Final Arbiter shall make a final and binding determination as to all matters in dispute relating to the calculation of the Closing Accounts Amount as promptly as practicable after its appointment (but no later than 45 days after the date of its appointment). The determination by the Final Arbiter of the amounts in dispute shall be based solely on presentations by Purchaser and Sellers, and shall not involve the Final Arbiter’s independent review. Any determination by the Final Arbiter shall not be outside the range defined by the respective amounts proposed by Purchaser and Sellers. The Final Arbiter shall send its written determination of the Included Payables, Included Receivables and Inventory Amount, each calculated as of the Closing Date, to Purchaser and Sellers, together with a calculation of the Closing Accounts Amount that results from such determination, and such determination of the Final Arbiter, and the resulting calculation of the Closing Accounts Amount, shall be binding on the parties, absent fraud or manifest error. The fees and expenses of the Final Arbiter shall be borne equally by Purchaser and Sellers.

4.5 Allocation of Purchase Price. Purchaser and Sellers shall use good faith efforts to attempt to reach agreement on the allocation of the Purchase Price and other relevant items (including, for example, the amount of Assumed Liabilities, adjustments to the Purchase Price and other consideration for Tax purposes) among the Purchased Assets, including goodwill and other assets, by the earlier of (x) six (6) months following the Closing Date, and (y) 60 days prior to the extended due date of the federal income tax return which includes the transactions contemplated herein, in accordance with Section 1060 of the Code and the Treasury regulations promulgated thereunder and any comparable provision of state, local or foreign Law, as appropriate (the “Allocation”). If Purchaser and Sellers reach a timely agreement regarding the Allocation, (a) such Allocation shall be binding on the parties, (b) the parties shall prepare and timely file all applicable federal and state income Tax forms (including Internal Revenue Service Form 8594) in a manner consistent with the Allocation, cooperate with each other in the preparation of such forms, and furnish each other with a copy of the final version of Form 8594 within a reasonable period before the filing date thereof, and (c) except as otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code (or any comparable provision of any state, local or foreign law), none of the parties shall take a position inconsistent with the Allocation on any Tax Return (including any forms required to be filed pursuant to Section 1060 of the Code), or otherwise. The parties recognize that the Allocation will not include Purchaser’s acquisition expenses or Sellers’ selling expenses, and Purchaser and Sellers will unilaterally allocate such expenses appropriately. If the parties are unable to reach a timely agreement regarding the Allocation, each party shall be entitled to adopt its own position regarding the Allocation.

Each Seller is a limited liability company or corporation duly formed or incorporated, validly existing and in good standing under the laws of the jurisdiction of its formation or incorporation and Sellers have the requisite power and authority to own the Purchased Assets, subject to, in the case of ASARCO, the limitations imposed on ASARCO as a result of having filed a petition for relief under the Bankruptcy Code.

Sellers are duly licensed or qualified to transact business and are in good standing in each jurisdiction in which their ownership or leasing of the Purchased Assets or the operation of its respective business makes such qualification necessary, except where the failure to be so qualified would not reasonably be expected to have, individually or in the aggregate, a Seller Material Adverse Effect.

6.2 Authorization of Agreement.

outstanding against Sellers under the Collective Bargaining Agreements (other than grievances, requests or demands attributable to or arising out of decisions, practices and policies made in the Ordinary Course of Business, including layoffs and reductions in force) that would reasonably be expected to have, individually or in the aggregate, a Seller Material Adverse Effect.

There are no liens for Taxes against any of the Purchased Assets.

6.14 Insurance. Section 6.14 of the Seller Disclosure Schedule lists the insurance policies maintained by Sellers that provide casualty, property damage and general liability coverage for the Purchased Assets. As of the Effective Date, all of such policies are in full force and effect.

In connection with such access, Purchaser’s representatives shall cooperate with Sellers’ representatives (one or more of whom may be present during any such inspection by Purchaser and Purchaser’s representatives) and shall use their reasonable best efforts to minimize any disruption of the Business. Purchaser agrees to abide by the terms of the Confidentiality Agreement and any safety rules or rules of conduct reasonably imposed by Sellers with respect to such access and any information furnished to it or its representatives pursuant to this Section 8.1.

For the avoidance of doubt, the foregoing shall not require Sellers to make any payments, incur any costs, or enter into or amend any Contracts or understandings, unless such payment,

In addition, no party shall take any action after the date hereof (other than any action required to be taken under this Agreement or to which the other parties shall have granted their consent) that could reasonably be expected to materially delay the obtaining of, or result in not obtaining, any consent, Order, Permit, qualification, exemption or waiver from any Governmental Authority or other Person required to be obtained prior to Closing; provided, however, that nothing in this Section 8.3 shall be construed as altering the rights and obligations of the parties under Section 3.5 or Section 8.10. To the extent any consideration is required to be paid to a third party in order to obtain any consents from third parties that may be necessary, proper or advisable to consummate the transactions contemplated by this Agreement and the Ancillary Agreements, such cost will be borne equally by Sellers and Purchaser.

(b) To the extent permitted by Applicable Law and subject to any limitations on access to information provided for in Section 8.1, each party shall consult with the other parties with respect to, and provide any information reasonably requested by the other party in connection with, all material filings made with any Governmental Authority in connection with this Agreement and the transactions contemplated hereby.

(c) In connection with the Original PSA, the parties made the required filing under the HSR Act with the Federal Trade Commission and Antitrust Division of the United States Department of Justice and the applicable “waiting period” thereunder expired on October 22, 2008 and the filing remains effective for a period of twelve months from the date of such

App. § 2170 et seq.) (the “Exon-Florio Provision”) with the Committee on Foreign Investment in the United States (“CFIUS”) with respect to the transactions contemplated by the Original PSA (the “CFIUS Notice”). The Purchaser and Sellers shall use commercially reasonable efforts to provide any additional information required by CFIUS in connection with this Agreement to obtain confirmation from CFIUS that the transactions contemplated by this Agreement do not fall within the scope of transactions requiring investigation under the Exon-Florio Provision. If requested by CFIUS in connection with its consideration of the transactions contemplated by this Agreement, the Purchaser and Sellers shall use commercially reasonable efforts to mitigate any concerns raised by CFIUS.

(e) Before and after the Closing Date, Sellers will use commercially reasonable efforts to cooperate with Purchaser in the conduct of the Arizona water rights adjudication cases to preserve Seller’s existing rights in the adjudication for Purchaser’s benefit after the Closing Date; provided, however, that Sellers shall have no obligation to continue such efforts upon the dissolution and winding up of ASARCO.

8.4 Preservation of Records. Subject to the other provisions of this Agreement, Purchaser and Guarantor shall, and shall cause their respective Affiliates to, preserve and keep in their possession all records held by them on and after the date hereof relating to the Purchased

Assets, for a period of seven years or such longer period as may be required by Applicable Law and shall make such records and personnel available to Sellers, or their Affiliates, as may reasonably be required by such party in connection with, among other things, any insurance claims, Legal Proceedings, collective bargaining or governmental investigations of Sellers or any of their Affiliates or in order to enable Sellers or any of their Affiliates to comply with their obligations under this Agreement, the Ancillary Agreements and each other agreement, document or instrument contemplated hereby or thereby. After the expiration of any applicable retention period, before Purchaser or any Guarantor shall dispose of any of such records, at least 90 days’ prior notice to such effect shall be given by Purchaser or Guarantor to Sellers (or a Person designated by Sellers) and Sellers shall have the opportunity (but not the obligation), at their sole cost and expense, to remove and retain all or any part of such records as they may in their sole discretion select.

The parties acknowledge that Guarantor and ASARCO previously executed a confidentiality agreement, dated July 6, 2007, (the “Confidentiality Agreement”), which Confidentiality Agreement shall continue in full force and effect in accordance with its terms and shall survive the execution and delivery of (and any termination of) this Agreement. Purchaser and Guarantor agree that this Agreement, the Ancillary Agreements and the terms and conditions of the transactions contemplated hereby and thereby shall be considered Evaluation Material as defined in, and subject to the terms of, the Confidentiality Agreement.

8.6 Public Announcements. Prior to the Closing Date, neither Sellers, nor Purchaser or Guarantor, or any of their respective Affiliates, agents or representatives, shall issue any press release or public statement concerning this Agreement or the transactions contemplated hereby without obtaining the prior written approval of the other parties hereto, unless such disclosure is required by Applicable Law, an Order of the Bankruptcy Court or by obligations pursuant to any agreement with any national securities exchange; provided, that the party intending to make such release shall give the other parties prior notice and shall use its commercially reasonable efforts consistent with such Applicable Law, Order or obligation to consult with the other party with respect to the text thereof.

8.7 Bankruptcy Matters.

(a) ASARCO shall use its reasonable best efforts to obtain prompt entry of the Plan Confirmation Order.

(b) ASARCO shall provide Purchaser with final drafts (promptly after such final drafts are prepared) of all documents, motions, orders, filings or pleadings that Sellers propose to file with the Bankruptcy Court which relate to (i) this Agreement or the transactions contemplated hereunder, (ii) the Sterlite Settlement Motion and the Sterlite Agreed Order, (iii) the Disclosure Statement, (iv) the Plan Confirmation Order and (v) the acquisition by Purchaser of the Purchased Assets, and will provide Purchaser with a reasonable opportunity to review such documents in advance of their service and filing to the extent reasonably practicable. Sellers shall consult and cooperate with Purchaser, and consider in good faith the views of Purchaser, with respect to all such filings. Except as permitted by Section 8.10, without the prior written consent of Purchaser (which consent shall not be unreasonably delayed or denied), once

filed with the Bankruptcy Court, Seller shall not seek to amend or modify any provision in the Sterlite Agreed Order, Disclosure Statement, the Plan or the Plan Confirmation Order to effect a change in the terms and conditions of the transactions contemplated by the Agreement which would reasonably be expected to have a material adverse effect on Purchaser (or Guarantor) or on the ability of Sellers and Purchaser (and Guarantor) to consummate the transactions contemplated hereby on or before the Termination Date; except that, Sellers may seek to amend or modify any provision in the Disclosure Statement, the Plan or the Plan Confirmation Order in connection with an Acquisition Proposal or Stand-Alone Plan in accordance with Section 8.10.

(c) Sellers, Purchaser and Guarantor shall each use commercially reasonable efforts to cooperate, assist and consult with each other to secure the entry of the Plan Confirmation Order following the date hereof, and to consummate the transactions contemplated by this Agreement (including (i) the assignment to and assumption by Purchaser of any Contract that is intended to be an Assumed Contracts in accordance with this Agreement, (ii) obtaining any consents required in connection therewith, and (iii) identifying any Contracts to allow Purchaser to furnish affidavits or other documents or information for filing with the Bankruptcy Court for the purposes, among others, of providing necessary assurances of performance by Purchaser and Guarantor under Section 3.5(a) of this Agreement). In the event that any Orders of the Bankruptcy Court relating to this Agreement shall be appealed by any Person (or a petition for certiorari or motion for reconsideration, amendment, clarification, modification, vacation, stay, rehearing or reargument shall be filed with respect to any such Order), subject to Section 13.1, Sellers, Purchaser and Guarantor will each cooperate in taking such steps to diligently defend against such appeal, petition or motion and Sellers and Purchaser shall use their commercially reasonable efforts to obtain an expedited resolution of any such appeal, petition or motion. Neither Purchaser nor Guarantor shall, without the prior written consent of Sellers, file, join in, or otherwise support in any manner whatsoever any motion or other pleading relating to the sale of the Purchased Assets. Nothing in this Section 8.7 shall be construed as altering the rights and obligations of Sellers under Section 8.10.

(d) By Order entered on January 14, 2009, ASARCO’s exclusive periods to file a chapter 11 plan and to obtain acceptances of such chapter 11 plan were extended to March 17, 2009 and May 18, 2009, respectively. From time to time, ASARCO will timely file a motion(s) as required to extend (i) ASARCO’s exclusive period to file a chapter 11 plan and (ii) ASARCO’s exclusive period to obtain acceptances of such chapter 11 plan. Purchaser acknowledges that the Bankruptcy Court terminated exclusivity under Section 1121(d) of the Bankruptcy Code to allow ASARCO Incorporated and Americas Mining Corporation, ASARCO’s direct and indirect parent companies, to file a chapter 11 plan and thus ASARCO’s motion to extend its exclusive periods as provided in this paragraph does not apply to ASARCO Incorporated and Americas Mining Corporation.

8.8 Title Insurance. Purchaser, at its own expense and at its option, may obtain commitments (each, a “Title Report”) for owner’s policies of title insurance with extended coverage, each in the aggregate amount of the Purchase Price allocable to the applicable Purchased Real Property, and leasehold policies of title insurance in the aggregate amount of the Purchase Price allocable to the applicable Leasehold Property (each such policy, a “Title Policy”) from a title company acceptable to Purchaser in its sole discretion (the “Title

Company”), and, at Purchaser’s election and sole cost and expense, a survey of each parcel of Real Property (each, a “Survey”). Sellers have delivered to Purchaser or shall promptly deliver to Purchaser after the date hereof, any existing Surveys of any parcel of Real Property any Seller may have in its possession. Seller shall have no obligation to obtain any new Surveys or updates to any existing Surveys. Purchaser shall provide to Sellers, to the extent obtained by Purchaser, a copy of each Title Report, each Title Policy and each Survey and all supplemental reports amending such Title Reports, Title Policies or revisions amending such Surveys.

8.9 Bonds and Assurances. Prior to Closing, Purchaser shall (i) cause Sellers to be fully, unconditionally and irrevocably released and discharged from the bonds, financial assurance obligations and guaranty obligations identified in Section 8.9 of the Seller Disclosure Schedule outstanding on the Closing Date and all such other bonds, financial assurance obligations and similar obligations incurred in the Ordinary Course of Business on or after the date of this Agreement and prior to the Closing (the “Bonds and Assurances”) and (ii) replace the Bonds and Assurances or act as a substituted obligor, guarantor or other counterparty to the Bonds and Assurances as required for the continued operation of the Business.

	(i)		Purchaser, Guarantor and Sellers acknowledge that Sellers may take any action deemed necessary by Sellers to demonstrate that (i) they have sought to obtain the highest and best value for the Purchased Assets and that (ii) consummation of the transactions contemplated by this Agreement will in fact yield the highest and best value for the Purchased Assets, including giving notice thereof to Sellers’ creditors, other bidders for the Purchased Assets and other interested parties, providing information about the Business to prospective bidders, entertaining and negotiating offers from such prospective bidders, and, if necessary, conducting an auction.

	(ii)		Without limiting the generality of Section 8.10(a)(i), each Seller and any director, officer, employee, investment banker, financial advisor, attorney, accountant or other advisor, agent or representative (collectively “*Representatives*”) of any Seller shall have the right (but not the obligation), acting under the direction of the Board of Directors of ASARCO or any committee thereof, to, directly or indirectly: (i) solicit, initiate, facilitate or encourage any Acquisition Proposal or proposal for a Stand-Alone Plan, including by way of providing access to third parties to non-public information pursuant to one or more confidentiality agreements; and (ii) enter into and maintain discussions or negotiations with respect to one or more Acquisition Proposals or any Stand-Alone Plan proposal or otherwise cooperate with or assist or participate in, or facilitate, any such discussions or negotiations.

	(iii)		Purchaser and Guarantor agree that none of them nor any of their respective Affiliates or Subsidiaries shall, and that each of them shall use their reasonable best efforts to cause each of their respective Representatives not to, directly or indirectly, discourage or interfere with any Acquisition Proposal or Stand-Alone Plan, or contact or participate in discussions with any Person regarding an Acquisition Proposal or proposal for a Stand-Alone Plan that, to Purchaser or Guarantor’s knowledge, has made, or is considering or participating in discussions or negotiations with any Seller or any Representative of any Seller regarding an Acquisition Proposal or proposal for a Stand-Alone Plan.

	(iv)		No Seller, nor any of its Representatives, shall have any liability to Purchaser or Guarantor, either under or relating to this Agreement, the Ancillary Agreements or any Applicable Law, by virtue of entering into or seeking Bankruptcy Court approval of an Acquisition Proposal or Stand-Alone Plan or the definitive agreement for any such Acquisition Proposal or Stand-Alone Plan. Any Seller may in its sole discretion enter into a definitive agreement with respect to such Acquisition Proposal or Stand-Alone Plan and Sellers may terminate this Agreement prior to or after entry into such a definitive agreement.

	(v)		Any action taken by any Seller or any Representative of any Seller in accordance with the provisions of this Section 8.10(a) are expressly acknowledged and agreed to be not in breach or violation of any covenant contained in this Agreement or that could be implied in this Agreement (including a covenant of good faith and/or fair dealing).

(b) Following the entry of the Sterlite Agreed Order by the Bankruptcy Court, ASARCO agrees that neither it nor any of its wholly-owned Subsidiaries shall, and that it shall direct its Representatives and its wholly-owned Subsidiaries’ Representatives not to, directly or indirectly, solicit any Acquisition Proposal; provided, however, that, nothing shall prevent ASARCO, its Board of Directors or any of its Representatives from taking any of the following actions:

(i) complying with its obligations under Applicable Law with regard to an Acquisition Proposal; or

(ii) (A) engaging in any negotiations or discussions with any Person who has made an unsolicited bona fide written Acquisition Proposal or (B) recommending an unsolicited Acquisition Proposal to the Creditor Constituents, if in the case of each of clause (A) and (B) above, the Board of Directors of ASARCO determines in good faith (after consultation with its legal and financial advisors and the Creditor Constituents) that (1) such action would be reasonably likely to be required in order to comply with its fiduciary duties under Applicable

Law and (2) such Acquisition Proposal is a Superior Proposal or is likely to lead to a Superior Proposal; or

(iii) communicating or engaging in discussions with any of the Creditor Constituents or their respective advisors or Representatives regarding any matter, whether Acquisition Proposal, proposal relating to a Stand-Alone Plan or otherwise.

(c) Notwithstanding anything herein to the contrary, Sellers and their Subsidiaries and their respective officers, directors, employees, attorneys, investment bankers, accountants and other agents and Representatives shall be permitted to (i) maintain and continue to provide access to the Seller Data Room to Persons that have executed a confidentiality agreement with ASARCO prior to the entry of the Sterlite Agreed Order and (ii) respond to any inquiries from and provide access to the Seller Data Room to Persons that have submitted a written bona fide (and unsolicited) Acquisition Proposal that ASARCO determines in good faith is a Superior Proposal (or is reasonably likely to lead to a Superior Proposal) and that have executed a confidentiality agreement with ASARCO. No Seller, nor any of its Affiliates shall have any liability to Purchaser or Purchaser Parent, either under or relating to this Agreement, the Ancillary Agreements or any Applicable Law, by virtue of entering into or seeking Bankruptcy Court approval of a Superior Proposal or the definitive agreement for such Superior Proposal, in each case, in accordance with the terms of this Section 8.10, following the receipt of any Superior Proposal, except as provided in Section 13.2(b)(v) upon termination of this Agreement.

(d) Sellers shall, as soon as practicable, provide Purchaser with the material terms and conditions of any Acquisition Proposal, and identity of the Person making such Acquisition Proposal, received by Sellers after the entry of the Sterlite Agreed Order by the Bankruptcy Court that the Board of Directors of ASARCO determines in accordance with Section 8.10(b)(ii) above to take any affirmative action to approve, or authorize negotiations of, a definitive agreement in respect of.

(e) Purchaser shall have the right (a “Matching/Topping Right”), within four Business Days after Purchaser receives a copy of the material terms and conditions of any Acquisition Proposal, and identity of the Person making such Acquisition Proposal, pursuant to Section 8.10(d), to deliver to Sellers an unconditional written offer to improve the terms and conditions contained in this Agreement so long as the Deemed Value of such improved offer (which Deemed Value will include the value of the amounts that would be owed to Purchaser under Section 13.2(b)(v) if such Acquisition Proposal were accepted and consummated) is at least equal to the Deemed Value of such pending Acquisition Proposal. Purchaser shall be under no obligation to exercise its Matching/Topping Right or to participate in any proceedings designed to elicit from Purchaser an equal or higher and better offer.

(f) If ASARCO terminates this Agreement pursuant to Section 13.1(d) or (e), and such Superior Proposal or Stand-Alone Plan, as applicable, that prompted such termination is definitively terminated prior to consummation thereof, then ASARCO shall offer Purchaser the right (the “Back-Up Bid Option”) to consummate the purchase and sale of the Purchased Assets and the assumption of the Assumed Liabilities in a transaction on substantially the same

terms and conditions as this Agreement; provided, however, the Back-Up Bid Option will expire with no further obligation to Purchaser at 5:00 p.m., Dallas, Texas time, on the tenth Business Day following the date on which the Back-Up Bid Option was offered to Purchaser unless prior to such time (A) ASARCO receives a definitive purchase and sale agreement executed by Purchaser and Guarantor in the form of this Agreement (including Article II) with only such modifications as are described in this Section 8.10(f) (the “Back-Up Bid Agreement”) and (B) ASARCO shall have received an originally executed letter of credit, enforceable against the issuer thereof, in the amount of $125,000,000.00 issued in favor of ASARCO by a Qualified Bank; provided, however, that if ASARCO has retained or drawn on the First L/C pursuant to Section 4.2(f), then the letter of credit shall be issued in the amount of $75,000,000.00. The Back-Up Bid Agreement shall contain the following modifications to this Agreement:

	(i)		all dates and deadlines shall be extended to such dates following execution of the Back-Up Bid Agreement as are consistent with the respective time periods between the Effective Date and the dates or deadlines contained in this Agreement;

	(ii)		the covenants contained in the subsections of Section 8.2 shall be reasonably revised as appropriate to reflect ASARCO’s operations at such time; provided, however, that Purchaser, Guarantor and Sellers, each acting reasonably, are able to agree in writing on such revisions prior to expiration of the Back-Up Bid Option; and

	(iii)		such other non-substantive changes as may be reasonably required under the circumstances and as may be agreed in writing among Purchaser, Guarantor and Sellers, each acting reasonably, prior to expiration of the Back-Up Bid Option.

Purchaser shall be entitled to seek specific performance to enforce its right to receive the offer of the Back-Up Bid Option from Sellers in accordance with this Section 8.10(f) without the necessity of proving actual damages or of posting any bond.

8.11 Risk of Loss; Casualty Loss. All risk of loss or damage to or destruction of the Purchased Assets, in whole or in part, shall be and remain with Sellers until Closing and upon Closing, the risk of loss or damages to or destruction of the Purchased Assets in whole or in part shall be and remain with Purchaser. If, between the date of this Agreement and the Closing, any of the Purchased Assets shall be destroyed or damaged in whole or in part by fire, earthquake, flood, other casualty or any other cause (the “Casualty”), then Purchaser shall acquire such Purchased Assets on an “as is” basis and take an assignment from Sellers of any insurance proceeds payable to Sellers in respect of the Casualty.

8.12 Further Assurances. Sellers, Purchaser and Guarantor agree that from and after the Closing Date, each of them will, and will cause their respective Affiliates to, execute and deliver such further instruments of conveyance and transfer and take such other action as may reasonably be requested by any party hereto to carry out the purposes and intents hereof.

This Section 8.13(a) shall not apply to transactions contemplated by, or Purchased Assets, proceeds or products received pursuant to, the Purchaser Promissory Note or Security Agreement.

(b) If, at any time on or after Closing, Purchaser receives any asset or any proceeds in respect of any Excluded Asset, whether or not in payment of any sum due to any Seller, or otherwise comes into possession of any Excluded Asset or product or proceed thereof, Purchaser shall turn over such asset or proceed to Sellers and pending such turn over, Purchaser shall hold such asset or proceed in trust for Sellers’ benefit.

8.14 Transition Services Agreement. The parties shall negotiate in good faith as promptly as practicable following the date of this Agreement a form of Transition Services Agreement whereby from and after the Closing until the completion by ASARCO and its subsidiaries (and any successor entities to ASARCO in the Bankruptcy Cases) of the wind down of its operations and the implementation of the Plan, Purchaser will provide to ASARCO the litigation support services, closing accounts statement services, and access to Real Property and Books and Records as set forth in Exhibit K and will make available the Transferred Employees or other personnel to provide to ASARCO the other wind down services described in Exhibit K in order to wind down operations, implement the Plan and otherwise administer the Bankruptcy Cases.

ARTICLE IX
EMPLOYEES AND EMPLOYEE BENEFITS

9.1 Employment.

(a) All of the employees of Sellers who are not union-represented and who are employed on the Closing Date, including those actively at work or on vacation, leave of absence or other approved absence from work and individuals who have received offers of employment but have not reported to work (“Non-Union Employees”), shall be offered employment with Purchaser on or before the Closing Date, subject to completion of all applications and forms for employment and benefits required by Applicable Law or required of similarly-situated employees of Guarantor, on the terms which, in the aggregate, are substantially equivalent to those provided to such Non-Union Employees prior to Closing. All union-represented employees of Sellers who are employed on the Closing Date, including those actively at work or on vacation, leave of absence or other approved absence from work and individuals who have received offers of employment but have not reported to work (“Union Employees”, and together with the Non-Union Employees, the “Employees”) shall be offered employment with Purchaser on or before the Closing Date, subject to completion of all applications and forms for employment and benefits required by Applicable Law or required of similarly-situated employees of Guarantor, in accordance with the terms of the labor agreement negotiated between Purchaser and the respective Union. Such persons who accept such offer on or before the

Closing Date shall be referred to as “Transferred Employees.” Notwithstanding the foregoing, this Section 9.1(a) shall not apply to those employees of Sellers whose principal services relate to litigation and bankruptcy administration (which employees Sellers agree to identify to Purchaser at least 30 days prior to Closing), and Purchaser will be under no obligation to offer employment to such employees of Sellers.

(b) Any liability or obligation that Sellers shall incur with respect to severance, benefits or termination of Employees as a result of Purchaser’s failure to provide Employees with pay, benefits and other terms and conditions of employment comparable in the aggregate to those provided to Employees as of the Closing or, where Purchaser’s provision of a comparable, in the aggregate, benefit is impracticable or impossible, Purchaser’s failure to provide a compensation and benefits package of comparable value at least sufficient to provide Purchaser and Sellers with a good faith defense to any allegation or claim that such Transferred Employees might make for severance or termination, will be an Assumed Liability.

9.2 Terms of Continued Employment.

(a) Purchaser agrees to provide to those Transferred Employees who were Non-Union Employees, for a period of at least 24 months following the Closing Date (i) levels of total compensation (including salary) and participation in Seller Employee Benefit Plans which, in the aggregate, are substantially equivalent to the levels of total compensation (including salary) and Seller Employee Benefit Plan participation, in the aggregate, of such Employees as in effect as of the Closing Date and (ii) at a work location no more than 50 miles from the individual’s work location as of the Closing Date; provided, however, that this shall not be construed to grant to any Transferred Employee a right to employment by Purchaser for any particular length of time. Nothing in this Section 9.2(a) shall in any way restrict the right of Purchaser to terminate any Transferred Employee who was a Non-Union Employee at any time for any reason not in violation of Contract or Applicable Law.

(b) Notwithstanding Section 9.2(a), if at any time during the 24-month period following the Closing Date the employment of any Transferred Employee is terminated other than for cause or is constructively terminated under the severance plan set forth in Section 9.2(b) of the Seller Disclosure Schedule, Purchaser shall provide the terminated Transferred Employee with severance benefits which are comparable, in the aggregate, to the severance benefits described in Section 9.2(b) of the Seller Disclosure Schedule.

9.3 Assumption of Plans. As of the Closing Date, Purchaser shall adopt and become the sponsor and employer for purposes of each and every Seller Employee Benefit Plan set forth in Section 9.3 of the Seller Disclosure Schedule and shall be substituted for Seller or its Subsidiaries who had theretofore been the sponsor of any such Seller Employee Benefit Plan. Effective as of the Closing, Purchaser shall be responsible for all benefits and liabilities with respect to such Seller Employee Benefit Plans, as such Seller Employee Benefit Plans may be amended or modified from time to time by written agreement between Purchaser and the Unions after the Closing Date.

9.4 Service Credit. Except as may otherwise be agreed in writing after the Closing Date between Purchaser and the Unions with respect to the applicable unionized employees, Purchaser shall cause to be provided to each Transferred Employee credit for prior service with Sellers or their Subsidiaries since their last day of hire for all purposes (including vesting, eligibility, benefit accrual and/or level of benefits) in all Purchaser employee benefit plans, programs, practices or arrangements, including fringe benefit plans, vacation and sick leave policies, severance plans or policies, retiree medical plans, defined benefit plans, matching contributions under defined contribution plans (including defined contribution retiree medical plans) maintained or provided by Purchaser or its Subsidiaries or Affiliates in which such Transferred Employees are eligible to participate after the Closing Date, to the extent such prior service credit would be extended under each applicable Seller Employee Benefit Plan; provided, however, that no such past service credit shall be granted to the extent that it would result in the duplication of benefits for the same period of service.

9.5 Vacation and Leave. Except for amounts of vacation and other accrued time off paid to Transferred Employees by Sellers at or promptly after the Closing Date, Purchaser shall provide each Transferred Employee credit for all of the Transferred Employee’s earned but unused vacation and sick leave and other time-off as of the Closing Date as determined under Seller’s time-off policies and Purchaser shall thereafter be responsible for providing commensurate vacation pay or pay in lieu of vacation as well as sick leave with respect to such employees for the credited vacation and sick leave. At least three days prior to Closing, Sellers shall provide Purchaser with a calculation of all of the Transferred Employee’s earned but unused vacation and sick leave and other accrued time-off.

9.6 Welfare Benefit Plans; Workers’ Compensation; Other Benefits.

(a) With respect to each Transferred Employee (including any beneficiary or the dependent thereof), Purchaser shall assume all liabilities and obligations for workers’ compensation benefits even if such liability or obligation relates to claims incurred (whether or not reported or paid) prior to the Closing Date. For purposes of this Section 9.6, a claim shall be deemed to be incurred when (i) with respect to medical, dental, health related benefits, accident and disability (including worker’s compensation benefits but not including wage continuation/replacement type benefits), the medical, dental, health related, accident or disability services with respect to such claim are performed and (ii) with respect to life insurance, when the death occurs.

(b) Effective as of the Closing Date, Purchaser shall be responsible for providing coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) to any Employee, his or her spouse or dependent person as to whom a “qualifying event” as defined in Section 4890B of the Code has occurred (i) prior to the Closing Date in the case of a “qualifying event” other than a termination of employment and (ii) in the case of a termination of employment “qualifying event” on or prior to the Closing Date. Purchaser shall also be responsible for providing COBRA coverage to any Employee, his or her spouse or dependent person as to whom a “qualifying event” occurs on or after the Closing Date including for a “qualifying event” that is a termination of employment on the Closing Date.

(c) Purchaser acknowledges that ASARCO has obligations under the Coal Act, including the obligations (i) to provide retiree health benefits to eligible beneficiaries and their dependents pursuant to Section 9711 of the Coal Act, 26 U.S.C. § 9711, (ii) to pay the annual prefunding premium and the monthly per beneficiary premium required pursuant to Section 9712(d)(1)(A) and (B) of the Coal Act, 26 U.S.C. § 9712(d)(1)(A) and (B), and (iii) to provide security to the UMWA 1992 Benefit Plan pursuant to Section 9712(d)(1)(C) of the Coal Act, 26 U.S.C. § 9712(d)(1)(C). Accordingly, Purchaser assumes and is responsible for all of the Coal Act obligations of ASARCO, including the obligations set forth in this paragraph.

(d) In addition to the obligations assumed pursuant to the other sections of Article IX and not in limitation thereof, Purchaser shall assume and be responsible for all of ASARCO’s obligations under the Collective Bargaining Agreement, as amended by that certain letter agreement entered into between the United Steelworkers of America and the Purchaser, dated June 23, 2008, which shall become effective on the Closing Date, and the retiree class action settlement agreement approved by the Bankruptcy Court by order dated March 15, 2007 (Docket No. 4178), which settled the cause of action captioned Asarco Incorporated et al. v. United Steelworkers of America, AFL-CIO/CLC, et al., No. CV-03-1297.

9.7 OSHA Medical Records; Other Records; Payroll Deductions. Purchaser shall accept delivery from Sellers of all OSHA exposure and other records with respect to the Business, and shall maintain such records and provide copies thereof to current and former employees engaged primarily in the conduct of the Business in compliance with OSHA. Purchaser shall obtain from Transferred Employees, as part of its hiring process or otherwise, their consents to the transfer of their medical and other records and all payroll deduction authorizations from Sellers to Purchaser. Notwithstanding anything to the contrary contained in Section 9.1, receipt of the consent contemplated by the immediately preceding sentence shall be considered a condition to the offer of employment required in Section 9.1, and any Employee who fails to provide such consent promptly shall cease to be a Transferred Employee, effective (retroactively, if applicable) as of the Closing Date.

9.8 Announcement. On or prior to the date hereof, Sellers and Purchaser have agreed (after consultation with the Unions) upon a form of joint announcement to employees concerning this Agreement and the transactions contemplated hereby and a communication plan concerning the method and timing of the delivery of such announcement. Contemporaneously with the execution and delivery of this Agreement (or promptly thereafter), the parties will deliver such announcement to employees in accordance with such communication plan.

9.9 Warn Act. Before the Closing Date, Sellers shall be responsible with respect to all current and former employees of Sellers for compliance with the Worker Adjustment and Retraining Notification Act of 1988 (the “WARN Act”) and any similar state or local law for an “employment loss” (as defined in the WARN Act) and occurring before the Closing Date as a result of actions take by Sellers. After the Closing Date, Purchaser shall be responsible with respect to all Transferred Employees for compliance with the WARN Act and any similar state or local Laws for an “employment loss” (as defined in the WARN Act) or temporary layoff (with no reasonable expectation of recall) occurring on or after the Closing Date as a result of actions taken by Purchaser. Section 9.9 of the Seller Disclosure Schedule lists the names and the sites of employment or facilities of those individuals who suffered an “employment loss” (as defined in

the WARN Act) or who have been placed on temporary layoff (with no reasonable expectation of recall) at any site of employment or facility of Sellers or any of its Subsidiaries during the 90-day period prior to the date hereof, together with the date of each such employment loss or temporary layoff (with no reasonable expectation of recall), which schedule shall be updated with respect to the period between the date hereof and the Closing Date.

ARTICLE X
TAX MATTERS

10.1 Transaction Taxes. Purchaser shall bear and be responsible for paying any sales, use, value added, goods and services, gross receipts, stamp, duty, stamp duty, transfer, documentary, registration, business and occupation, severance (to the extent imposed on the transfer of the Inventory) and other similar Taxes (including related penalties (civil or criminal), additions to Tax and interest) imposed by any Governmental Authority with respect to the transfer of the Purchased Assets under this Agreement (“Transaction Taxes”), regardless of whether any Tax authority seeks to collect such taxes from Sellers or Purchaser; provided, however, that Purchaser shall in no event bear or be responsible for Transaction Taxes in excess of $1,000,000. Purchaser shall also be responsible for (i) administering the payment of such Transaction Taxes required to be paid by Purchaser hereunder; (ii) defending or pursuing any proceedings related thereto; and (iii) paying any expenses, interest and penalties related thereto. Sellers shall cooperate with Purchaser and take actions reasonably requested by Purchaser to permit Transaction Taxes, if any, to be paid on a timely basis. Sellers shall give prompt written notice to Purchaser of any proposed adjustment or assessment of any Transaction Taxes with respect to the transactions contemplated hereby. In any proceedings, whether formal or informal, Sellers shall permit Purchaser to participate and control the defense of such proceeding with respect to such Transaction Taxes, and shall take all actions and execute all documents required to allow such participation.

10.2 Tax Prorations. As to any Purchased Assets acquired by Purchaser, Sellers and Purchaser shall apportion the liability for real and personal property taxes, ad valorem taxes and other similar Taxes imposed on a periodic basis and measured by the level of any item (“Periodic Taxes”) for all Tax periods including but not beginning or ending on the Closing Date (the “Proration Periods”). The Periodic Taxes described in this Section 10.2 shall be apportioned between Sellers and Purchaser as of the Closing Date, with Purchaser liable for that portion of the Periodic Taxes equal to the Periodic Tax for the Proration Period multiplied by a fraction, the numerator of which is the number of days remaining in the Proration Period after the Closing Date, and the denominator of which is the total number of days covered by such Proration Period. Sellers shall be liable for that portion of the Periodic Taxes for the Proration Period for which Purchaser is not liable under the preceding sentence. Purchaser and Sellers shall pay or be reimbursed for Periodic Taxes (including instances in which such Taxes have been paid before the Closing Date) on this prorated basis. If a payment on a tax bill is due after the Closing, the party that is legally required to make such payment shall make such payment and promptly forward an invoice to the other party for its pro rata share, if any. If the other party does not pay the invoice within 30 calendar days of receipt, the amount of such payment shall

bear interest at the rate of 6% per annum. The party responsible for paying a tax described in this Section 10.2 shall be responsible for administering the payment of (and any reimbursement for) such Tax. For purposes of this Section 10.2, the Proration Period for Periodic Taxes shall be the fiscal period for which such Taxes were assessed by the relevant Tax jurisdiction. Notwithstanding anything to the contrary contained herein, Purchaser shall be solely responsible for, promptly pay, and indemnify Sellers from and against, any and all assessments of taxes for the year in which Closing occurs, for all subsequent years and for prior years, in each case, due to change in land usage.

10.3 Tax Refunds. Any Tax refunds (including any interest related thereto) for which claims were filed prior to the Closing Date and which are received by Purchaser, its Affiliates or successors relating to Taxes attributable to the ownership or operation of the Purchased Assets during Tax periods or portions thereof ending on or before the Closing Date shall be for the account of Sellers, and Purchaser shall pay over to Sellers any such amount within five business days of receipt thereof. Any Tax refunds (including any interest related thereto) received by any Seller or its Affiliates or successors relating to Taxes attributable to the ownership or operation of the Purchased Assets during Tax periods or portions thereof beginning after the Closing Date shall be for the account of Purchaser, and Sellers shall pay over to Purchaser any such amount within five Business Days of receipt thereof. Each party shall, if the other party so requests and at such other party’s direction and expense, file or cause its Affiliates to file for and obtain any Tax refunds relating to Taxes attributable to the ownership or operations of the Purchased Assets that such other party is entitled to under this Section 10.3, and each party shall pay over to such other party any such amount within five Business Days of receipt thereof.

GUARANTEE

14.1 Guarantee.

(a) Guarantor hereby irrevocably, unconditionally and absolutely guarantees as a primary obligor and not as a surety, to Sellers the full and timely payment and due and punctual performance and discharge of all of Purchaser’s obligations under this Agreement and the Ancillary Agreements existing on the date hereof or hereafter of any kind or nature whatsoever, including the due and punctual payment of the Purchase Price and any other amount that Purchaser is or may become obligated to pay pursuant to this Agreement or the Ancillary Agreements (collectively, the “Obligations”). The guarantee under this Section 14.1 is an unconditional, irrevocable and absolute guaranty of timely payment and performance of the Obligations and not merely of collection. If for any reason whatsoever the Obligations shall not be fully and timely paid or performed, Guarantor shall promptly honor and perform its obligations to Sellers hereunder upon demand.

(b) To the fullest extent permitted by Applicable Law, the obligations of Guarantor hereunder shall remain in full force and effect without regard to, and shall not be affected or impaired by, (i) any change in the structure or ownership of Purchaser or Guarantor or the bankruptcy, insolvency, reorganization, dissolution, liquidation, or other similar proceeding relating to Purchaser, Guarantor or any Affiliate of either Purchaser or Guarantor; (ii) any neglect, delay, omission, failure or refusal of Purchaser or Sellers to take or prosecute any action in connection with this Agreement, the Ancillary Agreements or any other agreement, delivered in connection herewith or therewith; (iii) any extension, compromise, settlement, renewal or waiver of the time for any performance of or compliance with any of the Obligations; (iv) the existence of any claim, set-off or other right which Guarantor may have against Purchaser, Sellers or any other Person, whether in connection herewith or any unrelated transaction; (v) any invalidity or unenforceability of the Obligations; or (vi) any other act (other than prior full and indefeasible payment in cash and timely performance of the Obligations) or omission or delay by Purchaser or Sellers or any other Person that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of Guarantor hereunder.

(c) In connection with this Section 14.1, Guarantor unconditionally waives: (i) any right to receive demands, protests, or other notices of any kind or character whatsoever, as the same may pertain to Purchaser; (ii) any right to require Sellers to proceed first against Purchaser or to exhaust any security held by Sellers or to pursue any other remedy; (iii) any defense based upon an election of remedies by Sellers; (iv) any duty of Sellers to advise

Guarantor of any information known to Sellers regarding Purchaser or its ability to perform under this Agreement or any Ancillary Agreement; (v) all suretyship and other defenses of every kind and nature; (vi) all rights to and benefits under any defense based on or arising out of the voluntary or involuntary bankruptcy, insolvency, liquidation, dissolution, receivership, or other similar proceeding affecting Purchaser, or lack of capacity of Purchaser, which Purchaser or Guarantor may have to performance of any of the Obligations; (vii) notice of the creation of any Obligation or any notice of or proof of reliance by Sellers upon this Section 14.1 (the Obligations shall conclusively be deemed to have been created, contracted, incurred or renewed, extended, amended or waived in reliance upon this Section 14.1 and all dealings between Purchaser or Guarantor and Sellers shall be conclusively presumed to have been had or consummated in reliance upon this Section 14.1) or any notice of any other facts that may come to the attention of Sellers or Guarantor regarding the financial position of Purchaser; (viii) requirements of promptness or diligence on the part of Sellers; (ix) requirements on the part of Sellers to mitigate the damages resulting from any default hereunder or under the Obligations; (x) notice of acceptance hereof, of any action taken or omitted in reliance hereon, of any defaults by Purchaser in the payment or performance of the Obligations; (xi) all notices which may be required by Law or otherwise to preserve any of the rights of Sellers against Guarantor; and (xii) any other act or omission or thing or delay to do any other act or thing, which might in any manner or to any extent vary or limit Guarantor’s obligations hereunder or which might otherwise operate as a discharge of Guarantor.

(d) The obligations of Guarantor hereunder are primary, absolute, unconditional and irrevocable and will not be discharged by, and this Section 14.1 shall remain in full force and effect notwithstanding: (a) the assignment, conveyance or other transfer by Purchaser of any or all of its Obligations; (b) any insolvency, bankruptcy, reorganization, arrangement, composition, liquidation, dissolution or similar proceedings with respect to Purchaser; (c) any other occurrence whatsoever, except timely full and indefeasible payment and timely performance in full of all Obligations; or (d) any other circumstances whatsoever which might otherwise constitute a legal or equitable discharge, release or defense of a guarantor or surety, or which might otherwise limit recourse against Guarantor.

(e) The obligations of Guarantor under this Section 14.1 shall be automatically reinstated if and to the extent that for any reason any payment or other performance by or on behalf of Purchaser in respect of the Obligations is rescinded or must be otherwise restored, and Guarantor agrees that it will indemnify Sellers on demand for all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by Sellers in connection with such rescission or restoration. If in connection with the foregoing, Sellers are required to refund part or all of any payment of Purchaser, such payment by Sellers shall not constitute a release of Guarantor from any liability hereunder, and Guarantor’s liability hereunder shall be reinstated to the fullest extent allowed under Applicable Law and shall not be construed to be diminished in any manner.

(f) Guarantor shall not be entitled to be subrogated to any of the rights of Sellers against Purchaser or any collateral, security or guarantee or right of set-off held by Sellers for the payment or performance of the Obligations, nor shall Guarantor seek or be entitled to

seek any reimbursement from Purchaser in respect of performance made by Guarantor hereunder, until the Obligations are indefeasibly paid and performed in full.

(g) If any claim arising under or related to this Agreement or the Ancillary Agreements is reduced to judgment denominated in a currency (the “Judgment Currency”) other than that in which such sum is denominated in accordance with the applicable provisions of this Agreement (collectively the “Obligations Currency”), the judgment shall be for the equivalent in the Judgment Currency of the amount of the claim denominated in the Obligations Currency included in the judgment, determined as of the date of judgment. The equivalent of any Obligations Currency amount in any Judgment Currency shall be calculated at the spot rate for the purchase of the Obligations Currency with the Judgment Currency based on the daily noon day rate quoted by JPMorgan Chase Bank, N.A. (any costs of exchange payable in connection with such purchase shall be paid by Guarantor). Guarantor shall indemnify Sellers and hold Sellers harmless from and against all loss or damage resulting from any change in exchange rates between the date any claim is reduced to judgment and the date of payment thereof by Guarantor.

(h) All payments whatsoever made by the Guarantor under this Agreement and the Ancillary Agreement will be in lawful currency of the United States of America free and clear of, and without liability for withholding or deduction for or on account of, any present or future Taxes of whatever nature imposed or levied by or on behalf of any jurisdiction other than the United States (or any political subdivision or Taxing Authority of or in such jurisdiction) (hereinafter a “Non-US Taxing Jurisdiction”), unless the withholding or deduction of such Tax is compelled by law. If any deduction or withholding for any Tax of a Non-US Taxing Jurisdiction shall at any time be required in respect of any amounts to be paid by Guarantor under this Agreement or the Ancillary Agreements, Guarantor will pay to the relevant Non-US Taxing Jurisdiction the full amount required to be withheld, deducted or otherwise paid before penalties attach thereto or interest accrues thereon and pay to the Sellers such additional amounts as may be necessary in order that the net amounts paid to the Sellers pursuant to the terms of this Agreement or the Ancillary Agreements after such deduction, withholding or payment (including any required deduction or withholding of Tax on or with respect to such additional amount), shall be not less than the amounts then due and payable to such holder under the terms of this Agreement or the Ancillary Agreements before the assessment of such Tax.

(i) This Section 14.1 shall survive the Closing and shall remain in full force and effect. Guarantor agrees to indemnify and hold Sellers harmless from and against and to pay on demand all out-of-pocket costs and expenses (including reasonable legal fees and expenses) incurred by or on behalf of Sellers in any way relating to the collection and/or enforcement of Guarantor’s obligations under this Section 14.1.

14.2 Limitation. Each of the Sellers hereby acknowledges and agrees that, notwithstanding anything to the contrary contained herein, Guarantor is not a guarantor or surety of, and does not guarantee, any of the obligations of Purchaser under the Purchaser Promissory Note.

ARTICLE XV
MISCELLANEOUS

15.1 Nonsurvival of Representations, Warranties and Covenants. None of the representations, warranties, covenants or other agreements of the parties made herein, in the Seller Disclosure Schedule with respect to Sellers, in any Ancillary Agreement or any other agreement or instrument delivered pursuant to this Agreement, including any rights arising out of any breach of such representations, warranties, covenants or other agreements, shall survive the Closing except for those covenants and agreements contained herein and therein, which, by their terms, contemplate performance in whole or in part after the Closing, which shall survive in accordance with their terms (including, for the avoidance of doubt, Sections 8.1, 8.5, 8.6, and 8.10(f) and Articles IX, X, XII and XIV).

15.2 Remedies. Purchaser and Guarantor acknowledge and agree that the only remedy for breach of any representation or warranty made by Sellers, or any covenant required to be performed by Sellers prior to the Closing, shall be Purchaser’s option to terminate this Agreement pursuant to and to the extent permitted by Section 13.1, to receive the Deposit to the extent permitted by Section 4.2, to receive the expense reimbursement to the extent permitted by Section 13.2(b)(v) and to receive a release to the extent permitted by Section 2.1. Notwithstanding the foregoing, each party acknowledges and agrees that the other parties would be irreparably damaged if any provision of this Agreement is not performed in accordance with its specific terms and that any breach of this Agreement could not be adequately compensated in all cases by monetary damages alone.

15.5 Disclosure Schedules. For purposes of the representations and warranties of Sellers contained herein, disclosure in any section of the Seller Disclosure Schedule of any facts or circumstances shall be deemed to be adequate disclosure of such facts or circumstances with respect to the representations or warranties made by Sellers in the corresponding section of Article VI of this Agreement, unless it is readily apparent on the face of the disclosure contained in such section of the Seller Disclosure Schedule that such disclosure is applicable to another section of Article VI of this Agreement. Any information provided in the Seller Disclosure Schedule is solely for informational purposes, and the inclusion of such information shall not be deemed to enlarge or enhance any of the representations or warranties of Sellers. The inclusion of any information in any section of the Seller Disclosure Schedule or other document delivered by the parties pursuant to this Agreement shall not be deemed to be an admission or evidence of the materiality of such item, nor shall it establish a standard of materiality for any purpose whatsoever.

15.7 Submission to Jurisdiction; Consent to Service of Process.

(a) Without limiting any party’s right to appeal any Order of the Bankruptcy Court, (i) the Bankruptcy Court shall retain exclusive jurisdiction to enforce the terms of this Agreement and to decide any claims or disputes which may arise or result from, or be connected with, this Agreement, any breach or default hereunder, or the transactions contemplated hereby, and (ii) any and all Legal Proceedings related to the foregoing shall be filed and maintained only in the Bankruptcy Court, and the parties hereby consent to and submit to the jurisdiction and venue of the Bankruptcy Court and shall receive notices at such locations as indicated in Section 15.13; provided, however, that if the Bankruptcy Cases have been closed, the parties agree to file any such claim or dispute in the United States District Court for the Northern District of Texas and any appellate court thereof.

laying of venue of any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby brought in any court specified in paragraph (a) above, or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

(c) Each of the parties hereto hereby consents to process being served by any party to this Agreement in any suit, action or proceeding by the mailing of a copy thereof in accordance with the provisions of Section 15.13.

EACH PARTY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT, OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTIES WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

15.9 No Right of Set-Off. Each of Purchaser and Guarantor for itself and for its Subsidiaries, Affiliates, successors and assigns hereby unconditionally and irrevocably waives any rights of set-off, netting, offset, recoupment, or similar rights that Purchaser, Guarantor or any of their respective Subsidiaries, Affiliates, successors and assigns has or may have with respect to the payment of the Purchase Price or any other payments to be made by Purchaser or Guarantor pursuant to this Agreement, any Ancillary Agreement or any other document or instrument delivered by Purchaser or Guarantor in connection herewith.

15.11 Entire Agreement; Amendments and Waivers. This Agreement (including the Seller Disclosure Schedule and exhibits hereto), the Confidentiality Agreement and the Ancillary Agreements represent the entire understanding and agreement between the parties hereto with respect to the subject matter hereof and can be amended, supplemented or changed, and any provision hereof can be waived, only by written instrument making specific reference to this Agreement signed by the party against whom enforcement of any such amendment, supplement, modification or waiver is sought. No action taken pursuant to this Agreement, including any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty, covenant or agreement contained herein. The waiver by any party hereto of a breach of any provision of this Agreement

shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any party to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The parties acknowledge that all parties, through their legal counsel, played an equal role in drafting and/or had an equal opportunity to review and/or modify the provisions set forth in this Agreement. Thus, in the event of any misunderstanding, ambiguity, or dispute concerning this Agreement’s provisions, or interpretations, no rule of construction shall be applied that would result in having this Agreement interpreted against any party.
