Our Company

We design, manufacture and supply advanced systems that store gaseous fuels and monitor and control the pressure and flow of those fuels for use in internal combustion engines. Our components and systems enable internal combustion engines to operate on natural gas or propane. Our products improve efficiency, enhance power output, and reduce emissions by electronically sensing and regulating the proper proportion of fuel and air required by the internal combustion engine. Additionally, we have extensive engineering, design and systems integration experience with our customers’ requirements for product performance, durability and physical configuration. Based on over 45 years of technology development and expertise in producing cost-effective, safe and durable fuel technology systems, we believe we are positioned to provide enabling products and technologies in the rapidly expanding alternative fuel industry.

Our customers use our components and systems on engines ranging from one to 4,000 horsepower. We provide gaseous fuel components and systems to the transportation market and the industrial market, which includes the material handling and stationary and portable power generation markets.

A number of original equipment manufacturers, or OEMs, in the automotive, industrial and power generation industries, who are our customers, are developing alternative clean power systems using clean burning gaseous fuels, which decrease fuel costs, lessen dependence on crude oil and reduce harmful emissions of internal combustion engines. We offer the following products, kits and systems to these customers:

RISK FACTORS

Our business, results of operations and financial condition may be adversely affected by any one or more of the risks set forth below. You should carefully consider these risks before making an investment decision. Additional risks and uncertainties, including those that are not yet identified or that we currently think are immaterial, may also adversely affect our business, results of operations and financial condition. The market price of our common stock could decline due to any of these risks, and you could lose all or part of your investment.

We have substantial debt that we may be unable to service.

We are highly leveraged and have significant debt service obligations. As of December 31, 2003, we had aggregate outstanding indebtedness of $35.2 million and total stockholders’ equity of $57.1 million. In July 2003, we completed a financing that included the establishment of a new $12.0 million revolving credit facility and the issuance of a senior subordinated secured note in the amount of $20.0 million.

Our substantial debt could have important consequences, including the following:

• we will be required to use a substantial portion of our cash flow from operations to pay interest on our debt, thereby reducing our ability to fund working capital, capital expenditures, strategic acquisitions, investments and alliances and other general corporate requirements;

• our substantial leverage may increase our vulnerability to general economic downturns and adverse competitive and industry conditions and may place us at a competitive disadvantage compared to those of our competitors that are less leveraged;

• our debt service obligations may limit our flexibility to plan for, or react to, changes in our business and the industry in which we operate;

• our level of debt may make it difficult for us to raise additional financing on satisfactory terms; and

• if we were unable to comply with the financial and other restrictive covenants in our debt instruments, any such failure could, if not cured or waived, have a material adverse effect on our ability to fulfill our obligations and on our business or prospects generally, including the possibility that our lenders might foreclose on our assets.

• We currently are operating under waivers of financial covenants in both the Bison and LaSalle agreements relating to our EBITDA Covenant, Leverage Ratio Covenant and Fixed Change Covenant. These waivers relate to non-compliance as of December 31, 2003 and, in Bison’s case, continuing through December 31, 2004. The events of default under these loans will cause our applicable interest rates to increase as long as the circumstances continue unless we are successful in negotiating amendments to these covenants. The LaSalle loan increases the interest rate to prime plus 2%, which will increase our interest expense and our cash outflows by $25,000 per quarter. Under the Bison loan, the applicable interest rate increases by 0.5% per month up to a maximum of 3% or six months. We expect that the increase in the Bison interest rate will increase our interest expense by $150,000 during the first quarter of 2004, although in certain circumstances we are permitted to capitalize those interest payments by adding them to the principal balance outstanding under the Bison loan. We also are seeking to revise our financial covenants in both loans to reflect more current estimates of future financial performance. However, we cannot assure readers that the lenders will agree to amend our financial covenants or grant further or continuing waivers in the future. If we cannot obtain the necessary waivers or amendments, or return to compliance with these and all other loan covenants, our lenders may accelerate our debt, foreclose on our assets, or take other legal actions against us which, alone or in the aggregate, may have a material adverse effect on our business.

4

The terms of our debt may severely limit our ability to plan for or respond to changes in our business.

Our debt agreements contain a number of restrictive covenants that impose significant operating and financial restrictions on the company. Among other things, these restrictions limit our ability to:

• incur liens or make negative pledges on our assets;

• merge, consolidate or sell our assets;

• incur additional debt;

• pay dividends or redeem capital stock and prepay other debt;

• make investments and acquisitions;

• make capital expenditures; or

• amend our debt instruments and certain other material agreements.

Our debt also requires us to maintain specified financial ratios and meet specific financial tests. Our failure to comply with these covenants would result in events of default that, if not cured or waived, could result in us being required to repay these borrowings before their due date. If we were unable to make a required repayment or refinance these borrowings, our lenders could foreclose on our assets. If we were unable to refinance these borrowings on favorable terms, our business could be adversely impacted.

The Nasdaq Stock Market may take the position that we should have obtained shareholder approval for certain issuances of our outstanding securities, and if they were to take and prevail in that position, we could be subject to sanctions or delisting by The Nasdaq Stock Market.

Under applicable Nasdaq rules, a company with securities listed on the Nasdaq Stock Market must obtain shareholder approval before issuing securities if such issuance is not a public offering and involves the sale of 20% or more of the issuer’s outstanding common stock at a price less than the greater of book or market value. Since January 2002, we have issued shares of our common stock or securities convertible into or exercisable for our common stock in six separate transactions representing a total of 8,614,470 shares (excluding shares issued in connection with employee stock option plans, employee benefit plans and similar arrangements). Some of these shares were issued or are issuable at a price that represents a discount to the market price of our common stock on the date of issuance. If the sale of common stock to the selling stockholders were aggregated or integrated with one or more other transactions, or if two or more other transactions were to be integrated with one another, some of these combinations exceeded 20% of our outstanding common stock and thus would have required shareholder approval. Although not free from doubt, we believe that the sale of common stock to the selling stockholders should not be aggregated or integrated with any other transaction, and we believe that no series of other transactions would be integrated in a manner that would result in our being required to have obtained shareholder approval. We have not obtained any formal guidance from Nasdaq as to this matter. If Nasdaq were to determine that one or more of these transactions required shareholder approval, Nasdaq could halt trading of our common stock and initiate delisting of our common stock from The Nasdaq National Market. A delisting from Nasdaq, if it were to occur, could materially impair the liquidity of our securities and could adversely affect the trading price of our common stock.

We recently have experienced, and in the near term we will continue to experience, significant cash outflows that may limit our ability to grow and may materially and adversely impact our prospective revenues and liquidity.

We have experienced operating losses and net cash outflows. At December 31, 2003, our cash and cash equivalents totaled approximately $9.5 million and our working capital was $22.1 million. We have experienced significant cash outflows in connection with our purchase of an equity interest in BRC, S.r.l. and, due to our higher levels of debt, will have higher interest expense in the future. Our current cash position and upcoming cash obligations, especially if combined with stagnant or declining revenues, may force us to take steps such as

5

personnel reductions or curtailment of growth as a means to manage our liquidity. Such measures could have an adverse impact on research and development activities, our production capacity or other aspects of our business that might have a material adverse impact on results of operations. In some instances, these impacts may last beyond the term of the immediate cash shortfall.

Prevailing economic conditions and international dissension may disproportionately affect our business.

Because we depend heavily on sales to developing nations and because our business is based on fossil fuel markets, the effects of the Iraq conflict and continuing instability in the Middle East, as well as weaknesses in the U.S. and global economies, may cause our customers to delay orders, may result in interruptions in shipments to some customers or from some suppliers, or may have other effects that may decrease our revenues or increase our costs. These situations, whether alone or in combination with one or more risk factors discussed in this prospectus, may affect our business materially and adversely.

Our spin-off of our Quantum subsidiary is subject to tax risks for us and our stockholders, including restrictions on our or Quantum’s issuance of equity securities in order to maintain the tax-free status of the spin-off.

At the time of our spin-off of Quantum on July 23, 2002, we received an opinion of Morrison & Foerster LLP to the effect that the spin-off was tax-free to our stockholders for federal income tax purposes. The opinion of Morrison & Foerster LLP is not binding on the Internal Revenue Service and we can offer no assurance that the Internal Revenue Service or the courts will agree with their opinion. The opinion was also subject to specific assumptions and the accuracy and completeness of specific factual representations and statements made by us and Quantum, and we are subject to certain limitations on changes in our capital structure following the Quantum transaction. If these assumptions, representations or statements are incorrect or incomplete in any material respect, the conclusions set forth in the opinion may not be correct. Similarly, we can provide no assurances that our issuance of stock to BRC’s stockholders or in various post-spin-off equity issuances will not adversely impact the tax-free character of the Quantum spin-off.

Even if the spin-off is tax-free to our stockholders, it will be taxable to us if Section 355(e) of the Internal Revenue Code applies to the spin-off. Section 355(e) of the Internal Revenue Code will apply if 50% or more of our stock or Quantum stock, by vote or value, is acquired by one or more persons, other than our historic stockholders who receive Quantum common stock in the spin-off, acting pursuant to a plan or a series of related transactions that includes the spin-off. We cannot provide you any assurance that Section 355(e) of the Internal Revenue Code will not apply to the spin-off. Risk of the applicability of Section 355(e) of the Internal Revenue Code may also discourage, delay or prevent a merger, change of control, or other strategic or capital raising transactions involving our outstanding equity or issuance of new equity.

The growth of the alternative fuel market will have a significant impact on our business.

Our future success depends on the continued expansion of the alternative fuel industry, which has not yet expanded broadly. In the United States and certain of our other target markets, alternative fuel such as natural gas currently cannot be readily obtained by consumers for motor vehicle use and only a small percentage of motor vehicles manufactured in 2003 were equipped to use alternative fuels. We do not expect this trend to improve in the United States in the foreseeable future. We cannot assure you that the market for gaseous alternative fuel engines will expand broadly or, if it does, that it will result in increased sales of our advanced fuel system products. In addition, we have designed many of our products for alternative fuel vehicles powered by internal combustion engines, but not for alternative power sources, such as electricity or alternate forms of power. If the major growth in the alternative fuel market relates solely to those power sources, our revenues may not increase and may decline.

Users of gaseous fuel vehicles may not be able to obtain fuel conveniently and affordably, which may adversely affect the demand for our products.

Vehicles and equipment powered by gaseous alternative fuels currently run primarily on natural gas or propane. The construction of a distribution system to deliver natural gas and propane will require significant

6

investment by third parties. An adequate fuel distribution infrastructure may not be built. We are relying on third parties, most of which are committed to the existing gasoline infrastructure, to build this infrastructure. If these parties build a fuel distribution infrastructure, the fuel delivered through it, both due to the cost of the delivery system and the cost of the fuel itself, may have a higher price than users are willing to pay. If users cannot obtain fuel conveniently or affordably, a mass market for vehicles and equipment powered by gaseous alternative fuels is unlikely to develop.

Our ability to attract customers and sell products successfully in the alternative fuel industry also depends significantly on the current price differential between liquid fuels, such as petroleum and gasoline, and gaseous fuels, such as propane and natural gas. This price differential may not always exist. Should this differential narrow or disappear, it could adversely affect the demand of our products. The demand for our products could also be affected by the imposition of an excise tax on the production, sale, or distribution of gaseous fuels, which would be expected to reduce the economic advantage of alternative fuels.

We currently face and will continue to face significant competition, which could result in a decrease in our revenue.

We currently compete with companies that manufacture products to convert liquid-fueled internal combustion engines to gaseous fuels. Increases in the market for alternative fuel vehicles may cause automobile or engine manufacturers to develop and produce their own fuel conversion or fuel management equipment rather than purchasing the equipment from suppliers such as us. In addition, greater acceptance of alternative fuel engines may result in new competitors. Should any of these events occur, the total potential demand for our products could be adversely affected and cause us to lose existing business.

We face risks associated with marketing, distributing and servicing our products internationally.

We currently operate in Australia, Central America, China, Europe, Egypt, India, Japan, Mexico and South America and market our products and technologies in other international markets, including both industrialized and developing countries. Our international operations are subject to various risks common to international activities, such as the following:

• exposure to currency fluctuations;

• potential difficulties in enforcing contractual obligations and intellectual property rights;

• complying with a wide variety of laws and regulations, including product certification, environmental and import and export laws;

• political instability; and

• difficulties collecting international accounts receivable.

Our business may be subject to product liability claims, which could be expensive and could divert management’s attention.

As a supplier, we face an inherent exposure to product liability claims if our products (or the equipment into which our products are incorporated) malfunction in a way that results or is alleged to have resulted in personal injury or death. We may be named in product liability actions even if there is no evidence that our systems or components caused a loss. Product liability claims could result in significant losses from defense costs or damages awards. The sale of systems and components for the transportation industry entails a high risk of these claims. In addition, we may be required to participate in a recall involving these systems if any of our systems prove to be defective, or we may voluntarily initiate a recall or make payments related to such claims as a result of various industry or business practices or the need to maintain good customer relationships. Each of these actions would likely harm our reputation and lead to substantial expense. We cannot assure you that our product liability insurance will be sufficient to cover all product liability claims, that such claims will not exceed our insurance coverage limits or that such insurance will continue to be available on commercially reasonable terms, if at all. Any product liability claim brought against us could have a material adverse effect on our reputation and business.

Our products may become subject to future certification requirements or other regulations, which may impair our ability to market our products.

We must obtain product certification from governmental agencies, such as the Environmental Protection Agency and the California Air Resources Board, to sell certain of our products in the United States. A significant portion of our future sales will depend upon sales of fuel management products that are certified to meet existing and future air quality and energy standards. We cannot assure you that our products will continue to meet these standards. The failure to comply with these certification requirements could result in the recall of our products, civil penalties or criminal penalties.

Any new government regulation that affects our advanced fuel technologies, whether at the foreign, federal, state or local level, including any regulations relating to installation and servicing of these systems, may increase our costs and the price of our systems. As a result, these regulations may have a negative impact on our revenues and profitability and thereby harm our business, prospects, results of operations or financial condition.

New technologies could render our existing products obsolete.

New developments in technology may negatively affect the development or sale of some or all of our products or make our products obsolete. Our inability to enhance existing products in a timely manner or to develop and introduce new products that incorporate new technologies, conform to increasingly stringent emission standards and performance requirements, and achieve market acceptance in a timely manner could negatively impact our competitive position. New product development or modification is costly; involves significant research, development, time and expense; and may not necessarily result in the successful commercialization of any new products.

We depend on our intellectual property, and our failure to protect that intellectual property could adversely affect our future growth and success.

We rely on patent, trademark and copyright law, trade secret protection, and confidentiality and other agreements with our employees, customers, partners and others to protect our intellectual property. However, some of our intellectual property is not covered by any patent or patent application and, despite our precautions, it may be possible for third parties to obtain and use our intellectual property without authorization.

We do not know whether any patents will be issued from our patent applications, whether the reissue examination will be in our favor, or whether the scope of our issued patents is sufficiently broad to protect our technologies or processes. Moreover, patent applications and issued patents may be challenged or invalidated. We could incur substantial costs in prosecuting or defending patent infringement suits. Furthermore, the laws of some foreign countries may not protect intellectual property rights to the same extent as do the laws of the United States. For instance, it may be difficult for us to enforce certain of our intellectual property rights against third parties who may have inappropriately acquired interests in our intellectual property rights by filing unauthorized trademark applications in foreign countries to register the marks that we use because of their familiarity with our worldwide operations.

As part of our confidentiality procedures, we generally have entered into non-disclosure agreements with our employees, consultants and corporate partners and have attempted to control access to and distribution of our technologies, documentation and other proprietary information. We plan to continue these procedures. Despite these procedures, third parties could copy or otherwise obtain and make unauthorized use of our technologies or independently develop similar technologies. The steps we have taken and that we may take in the future may not prevent misappropriation of our solutions or technologies, particularly in foreign countries where laws or law enforcement practices may not protect our proprietary rights as fully as in the United States.

We cannot assure you that we will be successful in protecting our proprietary rights. Any infringement on any of our intellectual rights, could have an adverse effect on our ability to develop and sell successfully commercially competitive systems and components.

8

If third parties claim that our products infringe upon their intellectual property rights, we may be forced to expend significant financial resources and management time and our operating results would suffer.

Third parties may claim that our products and systems infringe upon third-party patents and other intellectual property rights. Identifying third-party patent rights can be particularly difficult, especially since patent applications are not published until 18 months after their filing dates. In the event a competitor were to challenge our patents, or assert that our products or processes infringe its patent or other intellectual property rights, we could incur substantial litigation costs, be forced to make expensive product modifications, pay substantial damages, or even be forced to cease our operations. Third-party infringement claims, regardless of their outcome, would not only drain our financial resources but also divert the time and effort of our management and could result in our customers or potential customers deferring or limiting their purchase or use of the affected products or services until resolution of the litigation.

We depend on third-party suppliers for the supply of key materials and components for our products.

We have established relationships with third-party suppliers that provide materials and components for our products. A supplier’s failure to supply materials or components in a timely manner or to supply materials and components that meet our quality, quantity or cost requirements, combined with a delay in our ability to obtain substitute sources for these materials and components in a timely manner or on terms acceptable to us, would harm our ability to manufacture our products or would significantly increase our production costs, either of which would negatively impact our results of operations and business. Adverse currency fluctuations may hinder our ability to economically procure key materials and services from overseas vendors and suppliers.

Potential fluctuations in our financial results could cause our stock price to decline.

Our revenue and operating results are subject to annual and quarterly fluctuations as a result of a variety of factors, including the following:

• budget cycles and funding arrangements of governmental agencies;

• purchasing cycles of fleet operators and other customers;

• the uncertainty of timing of deliveries of vehicles and other equipment on which our products are installed;

• the timing of implementation of government regulations promoting the use of our products; and

• general economic factors.

It is possible that our operating results in one or more future quarters may fall below the expectations of securities analysts and investors. If this occurs, the trading price of our common stock might be materially and adversely affected.

We could lose or fail to attract the personnel necessary to run our business.

Our success depends in large part on our ability to attract and retain key management, engineering, scientific, manufacturing and operating personnel. We lost some of our executive management in the Quantum spin-off, and it will take time for us to hire or train replacement personnel. Recruiting personnel for the industries in which we operate is highly competitive, and the failure to attract or retain qualified personnel could have a material adverse effect on our business.

Our business could be harmed if we fail to meet OEM specifications.

We offer integrated alternative fuel systems, which include tanks, brackets, electronics, software and other components required to allow these products to operate in alternative fuel applications. Customers for these systems require that these products meet strict OEM standards. Our compliance with these requirements has resulted in increased development, manufacturing, warranty and administrative costs. A significant increase in these costs could adversely affect our profitability. If we fail to meet OEM specifications on a timely basis, our relationships with OEMs may be harmed.

9

We may be subject to increased warranty claims.

In response to consumer demand, OEM, vehicle and industrial equipment manufacturers have been providing, and may continue to provide, increasingly longer warranty periods for their products, thus requiring their suppliers, such as us, to provide correspondingly longer product warranties. Due to the longer warranty periods, we could incur substantially greater warranty claims in the future.

We may experience unionized labor disputes at OEM facilities.

As we become more dependent on vehicle conversion programs with OEMs, we will become increasingly dependent on OEM production and the associated labor forces at OEM sites. Labor unions represent most of the labor forces at OEM facilities. In the past, labor disputes have occurred at OEM facilities, which adversely impacted our direct OEM product sales. Such labor disputes are likely to occur in the future and, if so, will negatively impact our product sales and profitability.

Changes in environmental policies could hurt the market for our products.

The market for alternative fuel vehicles and equipment, and the demand for our products are driven, to a significant degree, by local, state and federal regulations in the United States that relate to air quality and require the purchase of motor vehicles and equipment operating on alternative fuels. Similarly, foreign governmental regulations also affect our international business. These laws and regulations may change, which could result in transportation or equipment manufacturers abandoning their interest in alternative fueled powered vehicles. In addition, a failure by authorities to enforce current domestic and foreign laws or to adopt additional environmental laws could reduce the demand for our products.

Although many governments have identified as a significant priority the development of alternative energy sources, we cannot assure you that governments will not change their priorities or that any change they make would not materially adversely affect our revenue or the development of our products.

We may be subject to litigation if our stock price is volatile.

Our common stock has experienced and may experience in the future, price and volume fluctuations. Many factors may cause the market price for our common stock to decline, perhaps substantially, including the following:

• the effect of events of default occurring under our credit arrangements, particularly when combined with the increase in our outstanding loan commitments;

• failure to meet our product development and commercialization milestones;

• decreased demand for our common stock;

• failure of our revenue and operating results to meet the expectations of securities analysts or investors in any quarter;

• downward revisions in securities analysts’ estimates or changes in general market conditions;

• technological innovations by competitors or in competing technologies;

• investor perception of our industry or our prospects; or

• general technology or economic or regulatory trends.

In the past, companies that have experienced declines in the market price of their stock have been the subject of securities class action litigation. We may become involved in a securities class action litigation in the future. Litigation of this type often results in substantial costs and a diversion of management’s attention and resources, which could harm our business, prospects, results of operations or financial condition.

Provisions of Delaware law and of our charter and bylaws may it more difficult to take over our company, a fact that may reduce our stock price.

Provisions in our certificate of incorporation and bylaws and in the Delaware corporation law may make it difficult and expensive for a third party to pursue a tender offer, change in control or takeover attempt that our

10

management and Board of Directors oppose. Public stockholders that might desire to participate in one of these transactions may not have an opportunity to do so. We also have a staggered Board of Directors, which makes it difficult for stockholders to change the composition of the Board of Directors in any one year. These anti-takeover provisions could substantially impede the ability of public stockholders to benefit from a change in control or to change our management and Board of Directors.

We have a stockholder protection rights agreement that provides for a dividend of one right for each outstanding share of our common stock. Upon the occurrence of some events, including a person or entity’s acquisition of 15% or more of our common stock, each right will entitle the holder to purchase, at an exercise price of $45 per right, common stock with a market value equal to twice the exercise price, which could cause substantial dilution. The rights agreement may have the effect of deterring, delaying or preventing a change in control that might otherwise be in the best interests of our stockholders.

Future sales of our common stock could adversely affect our stock price.

Substantial sales of our common stock, including shares issued upon exercise of our outstanding options and warrants, in the public market or the perception by the market that these sales could occur, could lower our stock price or make it difficult for us to raise additional equity. As of March 18, 2004, we had 18,591,021 shares of common stock outstanding. Of these shares, 16,928,203 shares are currently freely tradable and 1,662,818 shares, which otherwise are freely tradable, are subject to a lockup agreement that restricts their resale until certain dates beginning in 2004. The following table presents the relevant expiration dates and the number of shares as to which the lockup agreement expires:

Date	Number of Shares Available for Sale
August 1, 2004	277,691
February 1, 2005	460,601
August 1, 2005	460,601
February 1, 2006	463,925

As of March 18, 2004 up to 795,000 shares were issuable upon the exercise of warrants outstanding as of that date, all of which will be freely tradable upon exercise thereof. Furthermore, as of March 18, 2004, up to 2,748,533 shares are issuable upon the exercise of options of which 764,004 are vested. Subject to applicable vesting and registration requirements, upon exercise of these options the underlying shares may be resold into the public market. In the case of outstanding options and warrants that have exercise prices less than the market price of our common stock from time to time, investors would experience dilution. We cannot predict if future sales of our common stock, or the availability of our common stock for sale, will harm the market price of our common stock or our ability to raise capital by offering equity securities.

We use words such as “anticipate,” “expect,” “intend,” “plan,” “believe,” “seek,” “estimate” and variations of these words and similar expressions to identify forward-looking statements. These statements are not guarantees of future performance and are subject to certain risks, uncertainties and other factors, some of which are beyond our control, are difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements. These risks and uncertainties include those described in the section above entitled “Risk Factors.” You should not place undue reliance on these forward-looking statements, which reflect our view only as of the date of this prospectus.

12

USE OF PROCEEDS

We will receive no proceeds from the sale of the securities described in this prospectus. The shares of common stock offered hereby are being offered for sale by the selling stockholders.

DIVIDEND POLICY

We have never paid dividends on our common stock. We previously paid cumulative cash dividends to the holders of our 1993 Series 1 Preferred Stock. On March 31, 1999, each share of preferred stock was converted into shares of our common stock. As a result, after March 31, 1999, we have no shares of preferred stock outstanding and have no obligation to pay any further dividends on those shares.

We currently intend to retain any earnings for use in developing and growing our business and do not anticipate paying any cash dividends on our common stock in the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our board of directors and will be dependent on our results of operations, financial condition, contractual restrictions, restrictions imposed by applicable law and other factors deemed relevant by the board of directors.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

Overview

We design, manufacture and supply components that store gaseous fuels and monitor and control the pressure and flow of those fuels for use in internal combustion engines. Historically, most of our revenues have been derived from the sale of the products that enable traditional internal combustion engines to run on clean burning alternative fuels such as propane and natural gas instead of gasoline. Based on over 45 years of technology development and expertise in producing cost-effective, safe, and durable fuel technology systems for engines, we believe that we are positioned to provide enabling products and technologies in the rapidly expanding alternative fuel industry.

Our U.S. Operations division sells products, including parts and conversion systems, for applications in the transportation and industrial markets, which include the material handling, stationary and portable power generator and general industrial markets. Our International Operations division provides distribution for our products in Asia, Australia, Europe, India, Japan and Mexico, predominantly from our U.S. Operations division and some product assembly. We classify the results of the Quantum division, which was spun-off in July 2002, as a discontinued operation on our consolidated financial statements.

Recent Developments

Quantum Spin-off.

On July 23, 2002, we completed the distribution and spin-off of our Quantum division by distributing one share of Quantum common stock for every share of IMPCO common stock held on the record date, which was July 5, 2002. Since we completed the Quantum spin-off in July 2002 we no longer are engaged in fuel cell technology research, although we do have a continuing collaboration arrangement for certain research and development activities. We believe that the spin-off enables IMPCO to optimize its growth strategies as a separate, stand-alone entity, based on its prospective capitalization and financing requirements, acquisition strategies, working capital requirements, projected cash flows from operations and desired credit ratings.

We have included a discussion on the Quantum reporting segment since the financial results of Quantum were included in the transition period ended December 31, 2002 and our fiscal years ended April 30, 2001 and 2002 consolidated results of operations. As a result of the spin-off of Quantum, we have reported Quantum as a discontinued operation. Readers should note that financial data that includes periods before the Quantum spin-off may not present a meaningful comparison with later periods because of the effect of the discontinued operation. Management expects the Quantum spin-off to have a favorable effect on our results of operations and cash flows from operations.

Capital Transactions.

On December 19, 2003 we concluded the issuance and sale of 1,500,000 shares of common stock to certain institutional investors at $6.40 per share, yielding net proceeds of approximately $9.0 million after discounts and commissions. The offering was conducted as a private placement under Section 4(2) of the Securities Act and Rule 506 promulgated thereunder. The proceeds of this offering were used to retire short-term debt and for working capital.

On July 22, 2003 we refinanced our debt to retire our $11.3 million debt to Bank of America, to finance the $7.0 million deferred payment to complete the 50% acquisition of B.R.C. Societá Responsabilitá Limitata (“BRC”), and to provide working capital. The debt restructuring consisted of two new loans. First, we entered into a senior subordinated secured promissory note and a related securities purchase agreement with Bison Capital Structured Equity Partners, LLC (“Bison”) for an aggregate borrowing of $20.0 million, with net

15

proceeds of approximately $17.3 million, and we issued to an affiliate of Bison warrants to purchase up to 500,000 shares of our common stock. The Bison loan has a nominal interest rate of 11.25%, subject to certain adjustments, and matures on July 22, 2007. Interest on the Bison loan is payable monthly in arrears. During periods in which an event of default exists under the Bison loan agreement, the interest rate increases at a rate of 0.50% per month up to a maximum of 6 months or 3%, and in certain circumstances, interest payments during an event of default can be capitalized, or added to the principal amount outstanding. Additionally, we entered into a revolving loan and security agreement and a related secured promissory note with LaSalle Business Credit, LLC (“LaSalle”). The LaSalle loan has a maximum borrowing limit of $12.0 million, with availability based upon a percentage of eligible inventory and eligible accounts receivable, and has an adjustable interest rate of 1% above LaSalle’s prime rate as announced from time to time and matures on July 22, 2006. Interest on the LaSalle loan is payable monthly in arrears. During periods in which an event of default exists under the LaSalle loan agreement, the interest rate increases to 2% above LaSalle’s prime rate. The Bison and LaSalle loans contain cross-default provisions such that an event of default existing under one loan generally constitutes an event of default under the other. At December 31, 2003 the amount borrowed under the LaSalle facility was $5.2 million with $1.8 million of availability. See also “Liquidity and Capital Resources.”

On October 3, 2002, we entered into an option agreement with the equity holders of BRC. Under the option agreement, we obtained the right to purchase from those equity holders 50% of the outstanding equity interest of BRC for approximately $23.8 million, which included the issuance of approximately 2.3 million shares of Company common stock (which the parties acknowledged and agreed were valued at $10.0 million). We announced on May 8, 2003 that we had exercised the option and that the purchase of 50% of BRC was completed pending a $7.0 million payment that represented a deferred portion of the purchase price due on September 30, 2003. On July 22, 2003, immediately after the refinancing of our debt as discussed above, we paid the deferred payment of $7.0 million to the equity holders of BRC completing the acquisition of the 50% equity interest in BRC. As of December 31, 2003, we had incurred acquisition costs of approximately $24.6 million, which are shown on the consolidated balance sheet as part of investment in affiliates. The corresponding costs incurred as of December 31, 2002 totaled $12.5 million. We use the equity method of accounting to recognize the investment in and the results of BRC in our consolidated financial results.

In accordance with the sale and purchase agreement executed in connection with the BRC investment, and subject to certain specified conditions, we have the option to acquire from the BRC equity holders at least 90% ownership in BRC after the 2006 calendar year based upon a price determined by a multiple of Earnings Before Interest and Taxes adjusted by Depreciation and Amortization (“EBITDA”) and other quantitative factors. We believe the acquisition of 50% of BRC affords us a valuable strategic opportunity to expand in markets that are complementary to the traditional IMPCO markets for industrial applications. M.T.M. S.r.l., a subsidiary of BRC, has been developing, manufacturing and marketing alternative gaseous fuel products and systems for automobiles for more than twenty years. We believe BRC is a leader in the transportation sector of the gaseous fuels products market. BRC conducts business in all fifteen European Union nations, as well as ten Eastern European countries and a number of developing nations including Brazil, Argentina, Chile, Australia, India, China, Thailand and South Korea. We believe this relationship with BRC will enable us to expand our position in end-user markets across a vast portion of the world. In addition, we anticipate that the manufacturing strengths of BRC, coupled with the additional product volume we hope to derive from the relationship, should result in significant productivity improvements. Furthermore, we believe that this agreement places us in the position to exploit our combined technology and product strengths through a strong global representation in the emerging alternative fuels industry.

Change of Fiscal Year

Our fiscal year had traditionally ended on April 30, and our fiscal quarters on July 31, October 31 and January 31. On November 14, 2002 we changed our fiscal year so that effective January 1, 2003 our fiscal year will be the calendar year. Accordingly, we filed a transition report for the eight-month period ended December 31, 2002 and this Annual Report for the fiscal year ended December 31, 2003 on Form 10-K, respectively.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to bad debts, goodwill, taxes, inventories, warranty obligations, long-term service contracts, and contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We believe the following critical accounting policies affect the more significant judgments and estimates used in the preparation of our consolidated financial statements:

We recognize revenue for product sales when title is transferred, ordinarily when products are shipped, and when management is reasonably assured of collectibility. We provide for returns and allowances as circumstances and facts require.

We provide for the estimated cost of product warranties at the time revenue is recognized. While we engage in product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers, our warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from our estimates, revisions to the estimated warranty liability would be required.

We write down our inventory for estimated obsolescence and unmarketable inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required.

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances would be required.

We annually evaluate the carrying value of goodwill and other intangible assets using the impairment method. If the carrying value of the net assets and liabilities underlying the goodwill recorded on the financial statements exceeds the fair value of the net assets and liabilities based on discounted cash flows, an impairment charge is recognized against goodwill following a restatement of the tangible assets and liabilities at fair values.

We operate wholly owned and majority owned subsidiaries. We recorded goodwill at the time of purchase for the amount of the purchase price over the fair value of the assets and liabilities acquired. Future adverse changes in market conditions or poor operating results of underlying investments could result in losses or an inability to recover the carrying value of the goodwill, thereby possibly requiring an impairment charge in the future.

We record a deferred tax asset and assess the adequacy of a valuation allowance for the purpose of carrying a net deferred tax asset at an amount that we believe will be recovered in the next three years. During the transition period ended December 31, 2002 and during the year ended December 31, 2003, we recorded $24.0 million and $2.5 million, respectively, for valuation allowances for that portion of deferred tax assets that we believe is less likely than not to be realized in the next three years. We consider our recent operating results, future taxable income and ongoing prudent and feasible tax planning strategies in determining the amount of the valuation allowance required for the portion of the deferred tax asset that is not likely to be realized in the next

17

three years, notwithstanding that a significant portion of our deferred tax assets may have a longer life under applicable tax laws. On a quarterly basis, we continue to analyze the deferred tax asset and the reserve required for the portion of the asset that is unlikely to be realized in the next three years. Future adverse changes in market conditions, poor operating results or a decline in our projections about future profitability may affect our assessment of the adequacy of the reserve. In the event that we determine that it is more likely than not that we would be unable to realize an additional portion of our net deferred tax asset, an additional adjustment to the deferred tax asset valuation allowance would be charged to income in the period such determination was made.

Results of Operations

Fiscal Year Ended December 31, 2003 and Twelve-Month Period ended December 31, 2002

In November 2002, we changed our fiscal year-end from April 30 to December 31. The basis of comparison for the discussion that follows for the fiscal year ended December 31, 2003 consists of the eight months ended December 31, 2002, the three months ended April 30, 2002 and the month ended January 31, 2002. We have provided (in thousands of dollars) summary of the consolidated statement of operations for 2002:

	Month Ended January 31, 2002			Three Months Ended April 30, 2002			Eight Months Ended December 31, 2002			Year Ended December 31, 2002
Revenues	$	5,236		$	16,733		$	46,421		$	68,390
Costs and expenses:

Operating expenses		1,888			6,156			14,557			22,601
Total costs and expenses		5,671			17,804			47,628			71,103
Operating loss		(435	)		(1,071	)		(1,207	)		(2,713	)
Interest expense, net		75			33			883			991
Loss from continuing operations, net of tax		(153	)		(899	)		(25,279	)		(26,331	)
Loss on discontinued operation		(2,380	)		(4,757	)		(3,115	)		(10,252	)
Net income (loss)	$	(2,533	)	$	(5,656	)	$	(28,394	)	$	(36,583	)

Net revenue increased $6.3 million, or 9.3%, to $74.7 million in the fiscal year ended December 31, 2003 from $68.4 million for the twelve months ended December 31, 2002. Unless otherwise noted, comparisons for fiscal 2003 are to the unaudited 12 month period ended December 31, 2002. Revenue in the three months ended December 31, 2003 was $18.2 million or 21.3% higher than revenues of $15.0 million during the corresponding period of 2002. The annual revenue increase was due to a $7.6 million increase in net sales to the industrial market partially offset by a $1.3 million decline in net sales to the transportation market. The increase in the industrial market was due primarily to the continued economic recovery affecting the industrial markets in the United States and in Europe since the downturn that followed the events of September 11, 2001. The quarterly increase in revenues is attributable to the launch of our new Spectrum product line. During the fourth quarter of 2003, we began shipping the Spectrum product line including certified engine packages and fuel systems in response to the new federal regulations, effective January 1, 2004, requiring that certain “off-road” vehicles and industrial applications meet more stringent exhaust standards. Additionally, we expect that revenues will increase during the first part of 2004 as compared to the same period of 2003 in response to increased deliveries of Spectrum and improved economic conditions in the markets we serve.

Net revenues and operating income for our reporting segments for the fiscal year 2003 as compared to 2002 are as follows (in thousands of dollars):

	Revenues						Operating Income/(Loss)
	Twelve Months Ended December 31,						Twelve Months Ended December 31,
	2002			2003			2002			2003

(1) Represents corporate expenses not allocated to any operating segments

The following table sets forth our product revenues by application across all reporting segments for 2003 and the corresponding period of 2002:

	Revenues
	Twelve Months Ended December 31,
	2002		2003
Industrial	$	37,365	$	45,217
Transportation		31,025		29,523
Total	$	68,390	$	74,740

During the twelve month periods ended December 31, 2003 and 2002, our revenue was generated in the following geographic regions by percent proportions:

	Twelve Months Ended December 31,
	2002		2003
United States and Canada	43.3	%	42.9	%
Asia & Pacific Rim	10.0	%	12.3	%
Europe	23.7	%	29.1	%
Latin America	23.0	%	15.7	%

Operating loss improved by $2.2 million, or 82%, from a loss of $2.7 million in 2002 to a loss of $0.5 million in 2003. This decrease in operating loss is the result of increased revenues of approximately $6.3 million, which contributed $1.8 million in additional operating income; higher gross margin percentage of 2% (compared to 29% in 2002), which contributed $1.2 million; partially offset by increased operating expenses of approximately $0.8 million.

U.S. Operations.    Net revenues from U.S. Operations increased $2.6 million, or 5.3%, to $52.0 million in the twelve months ended December 31, 2003 from net revenues of $49.3 million in the same period in 2002. The increase in sales during 2003 is due primarily to a $5.5 million increase in gross revenue for the industrial market offset by a $2.9 million decline in revenues for the transportation market. We believe that U.S. Operations will benefit beginning in the fourth quarter of 2003 and 2004 from an anticipated increase in revenues attributed to the new federal regulations affecting certain “off-road” vehicles and industrial applications requiring more stringent exhaust standards.

Gross profit in this segment increased by $0.1 million in 2003 due to $0.6 million in higher margin contribution from the $2.6 million in higher revenues offset by approximately $0.5 million due to reduced gross profit percentages resulting from unfavorable changes in product mix.

19

For 2003, operating income increased by $2.3 million, or 105.8%, as compared to the same period in 2002. The increase in operating income was due to an increase in gross profit of $0.1 million and a decrease in operating expenses of $2.2 million. Significant cost reductions occurred in sales and marketing and the research functions since the third quarter of 2002 following the Quantum spin-off.

International Operations.    For the fiscal year ended December 31, 2003, net revenue increased by approximately $0.2 million to $36.1 million, compared to $35.9 million reported for the same period in the prior calendar year. The growth in revenue was due primarily to a 30% increase in revenues from our European and Asian subsidiaries offset by a reduction of 32% in revenues from our Mexican subsidiary. By market segment, the increase in sales during 2003 as compared to 2002 was caused primarily by a $2.9 million increase in gross revenue from the industrial market offset by a $2.7 million decline in revenues from the transportation market. Foreign currency fluctuations had the effect of increasing revenue in U.S. dollars by approximately $2.2 million.

Gross profit for 2003 increased by approximately $2.6 million, or 32.8%, as compared to the same period in 2002. The increase in gross margin was attributed primarily to changes in product mix that contributed positively to gross margin.

During 2003, operating income from international operations increased by approximately $1.4 million, or 622%, as compared to 2002. The increase in operating profit was due to the increase in gross profit of $2.6 million offset by increases in operating expenses of $1.2 million. The increase in operating expenses was associated partly with amounts recognized as bad debt expense in our Mexican subsidiary for $0.5 million and higher expenses in our European subsidiaries related to the weakening of the dollar against the euro throughout 2003. During 2003, we recognized $0.5 million in higher bad debt expense in Mexico primarily due to the write-off of another receivable of $0.4 million which we believe to be substantially uncollectible.

Corporate Expenses.    Corporate expenses consists of general and administrative expenses at the corporate level to support our operating segments in areas such as executive management, finance, human resources, management information systems, legal services and investor relations. Corporate expenses for 2003 were approximately $2.4 million more than the corresponding period of 2002 and are attributable to higher insurance premiums, higher depreciation expense for installation of new information systems, higher legal, investment banking and accounting expenses associated with LaSalle credit facility and the Bison notes to refinance the Bank of America debt, higher consulting fees and outside services, and reduced recoveries of corporate overhead in 2003 to Quantum and the foreign affiliates.

Interest Expense.    Net interest expense for 2003 was approximately $4.0 million compared to $1.0 million for 2002 due primarily to the carrying value of our debt increasing from $14.3 million at December 31, 2002 to $23.7 million at December 31, 2003. In July 2003, we entered into lending agreements with Bison and LaSalle for $20.0 million and $12.0 million, respectively, for the primary purposes of repaying the Bank of America debt and financing the deferred portion of the BRC 50% acquisition of $7.0 million. The interest rates for Bison and LaSalle were an effective interest rate of 15.9% and a variable interest rate equal to LaSalle Bank’s prime plus 1%, respectively. As of December 31, 2003, the amount borrowed under the LaSalle line was approximately $5.2 million and the interest expense recognized in the statement of operations for the year ended December 31, 2003 was $0.2 million, which included $77,000 in amortization expense related to debt issuance costs of approximately $0.3 million. Under the Bison loan agreement interest expense was approximately $1.8 million of which $0.8 million was attributed to the amortization of $2.2 million in deferred debt issuance costs, $2.6 million associated with the fair value of 500,000 warrants issued in connection with the notes, and the $2.7 million loan discount associated with the difference between the $20.0 million loan amount and the actual net proceeds of $17.3 million. During 2003, we also incurred interest expense in connection with several bridge loans totaling approximately $4.1 million that were repaid completely by December 2003. Interest expense for the bridge loans included cash payments of approximately $0.5 million and amortization expense of $0.7 million associated with warrants issued to the holders of the bridge loans. Interest expense in the amount of approximately $0.7 million was recognized during 2003 for the Bank of American terms loans and lines of credit, all of which were repaid in July 2003.

20

Provision For Income Taxes.    During 2002, we established a $24.0 million valuation allowance for deferred tax assets on the basis that we believed that it is more likely than not that a portion of our deferred tax asset will not be realized and established a valuation allowance for those assets that are not likely to be utilized in the next three years, notwithstanding that some of these may have longer lives under applicable tax laws. During 2003, we increased by approximately $2.5 million the valuation allowance to $26.5 million on the basis that the increase in deferred tax asset and related net operating losses from the domestic pre-tax loss in 2003 of $6.1 million would more likely than not be unrecoverable over the next three years. The effect of the increase in the valuation allowance was that no income tax benefit was recognized for domestic tax purposes during 2003. Federal net operating loss carryforwards of $72.0 million will begin to expire in 2021. We have federal and state research and development credit carryforwards aggregating approximately $9.7 million. Federal research and development credits totaling $5.1 million will begin to expire in 2009. State research and development credits of $4.6 million have no expiration. As of December 31, 2003, the deferred tax asset, net of the $26.5 million reserve, was $9.8 million. The income tax expense of $0.7 million during 2003 was attributed to our international operations, which had a pre-tax income of approximately $1.6 million. We believe that, based on our history of prior operating earnings and our expectations for the future, our operating income will more likely than not be sufficient to recognize fully the net deferred tax assets within the next three years. Future adverse changes in market conditions, poor operating results or a decline in our projections about future profitability may affect our assessment of the adequacy of the reserve. In the event that we determine that it is more likely than not that we would be unable to realize an additional portion of our net deferred tax asset, an additional adjustment to the deferred tax asset valuation allowance would be charged to income in the period such determination was made.

Equity Share of Income (Loss) of Unconsolidated Affiliates.    We recognized a $1.1 million expense before tax corresponding to our share in the losses of unconsolidated affiliates primarily due to our 50% ownership in BRC of Italy for the period of July 22, 2003 to December 31, 2003. Our share of the BRC loss was approximately $0.5 million. The BRC loss was attributed to reduced revenues of €2.6 million ($3.0 million) and reduced operating income of €2.1 million ($2.4 million) for the twelve months ended December 31, 2003 compared to the corresponding period of 2002. Foreign exchange transaction loss totaled €0.3 million ($0.3 million) during the fourth quarter of 2003 due to the continued strengthening of the euro relative to other currencies in which BRC settled transactions. In accordance with the equity method of accounting for business combinations, we recognized amortization expense of $0.3 million for the difference between the book value and the fair value of our share of the net assets acquired. This amortization expense will continue to be recognized until 2008 at an annual rate of approximately $0.7 million.

Discontinued Operation.    We completed the spin-off of Quantum on July 23, 2002. We did not recognize any activity during 2003 related to the discontinued operation. The loss from discontinued operation during the twelve months ended December 31, 2002 was $10.3 million.

Eight-Month Periods Ended December 31, 2002 and 2001

Net revenues and operating income for our reporting segments for the eight-month period ended December 31, 2002 (“2002”) or “transition period” and the corresponding period of 2001 are as follows:

	Revenues						Operating Income/(Loss)
	Eight Months Ended December 31,						Eight Months Ended December 31,
	2001			2002			2001			2002
U.S. Operations	$	35,868		$	33,151		$	2,962		$	1,751
International Operations		22,222			25,304			1,016			637

The following table sets forth our product revenues by application across all reporting segments for the transition period and the corresponding period of 2001:

	Revenues
	Eight Months Ended December 31,
	2001		2002
Industrial	$	28,455	$	23,468
Transportation		17,252		22,953
Total	$	45,707	$	46,421

During the transition period and the corresponding period of 2001, our revenue was generated in the following geographic regions by percent proportions:

	Eight Months Ended December 31,
	2001		2002
United States and Canada	42.7	%	40.5	%
Asia & Pacific Rim	10.9	%	10.7	%
Europe	30.3	%	23.0	%
Latin America	16.1	%	25.8	%

Net revenue increased $0.7 million, or 1.6%, to $46.4 million in the transition period from $45.7 million in 2001. The revenue increase was primarily due to a $5.7 million increase in net sales of our products to the transportation market partially offset by a $5.0 million decline in net sales of our products to the industrial market. The decline in the industrial market was due primarily to the continued economic slowdown affecting the industrial markets in the United States, particularly following the events of September 11, 2001. We believe our sales into the transportation market have continued to grow, particularly in Mexico, due to a favorable price differential between conventional and alternative fuels.

Our operating loss increased by approximately $0.9 million, or 352.5% from a $0.3 million loss in 2001 to a $1.2 million operating loss in 2002. The increase in operating loss in 2002 is due primarily to reduced gross profit on product shipments from both the U.S. and International operations partially offset by reduced expenses for research and development and selling, general and administrative expenses.

U.S. Operations.    Net revenues from U.S. Operations decreased $2.7 million, or 7.6%, to $33.2 million in the eight-month transition period ended December 31, 2002 from net revenues of $35.9 million in the same period in 2001. The decrease in sales during the current period is due primarily to a $9.0 million decline in gross revenue for the industrial market offset by a $6.3 million increase in revenues for the transportation market.

Gross profit in this segment decreased $2.5 million, or 24.7%, to $7.6 million in the transition period of 2002 from $10.0 million in 2001. Approximately $0.8 million of the decline in gross profit was due to a decline in revenue and approximately $1.7 million of the decline was due to comparably lower margins in the transportation market than the industrial market.

For the transition period ended 2002, operating income decreased by $1.2 million, or 41%, as compared to the same period in 2001. The reduction in operating profit was due to a reduction in gross profit of $2.5 million offset by a reduction in operating expenses of $1.3 million. Approximately $1.0 million of the reduction in operating expenses was due to lower research and development expenses.

22

International Operations.    For the eight months ended December 31, 2002, net revenue increased by approximately $3.1 million to $25.3 million, compared to $22.2 million reported for the same period in the prior calendar year. The growth in revenue was due primarily to a 97% increase in revenues from our Mexican subsidiary offset by a reduction of 24% in revenues from our European subsidiary. By market segment, the increase in sales during 2002 was caused primarily by a $5.0 million increase in gross revenue from the transportation market offset by a $1.9 million decline in revenues from the industrial market.

Gross profit for the transition period of 2002 decreased approximately $0.4 million, or 5.9%, as compared to the same period in 2001. Approximately $1.2 million of the decline in gross profit was due to changes in product mix offset by approximately $0.8 million attributable to the increase in revenue.

During the transition period of 2002, operating income decreased by approximately $0.4 million, or 37.3%, as compared to the same periods in the prior calendar year. The reduction in operating profit was due to a reduction in gross profit of $0.4 million.

Corporate Expenses.    Corporate expenses consists of general and administrative expenses at the corporate level to support our operating segments in areas such as executive management, finance, human resources, management information systems, legal services and investor relations. As of May 1, 2002, the amortization of goodwill and other intangible assets is no longer recorded as a corporate expense due to the implementation of Financial Accounting Standards Board Statement No. 142, “Goodwill and Other Intangible Assets”. During 2001, approximately $0.5 million of amortization of goodwill and other intangibles was charged to corporate expense. Corporate expenses for 2002 were approximately $1.0 million less than the corresponding period of calendar year 2001 and are attributable to legal and consulting expenses totaling approximately $1.2 million that were incurred during 2001 in connection with Quantum spin-off costs and an S-3 registration statement filing that was withdrawn on September 20, 2001 offset by higher one-time expenses for severance, accelerated accruals for audit fees and investor relations expenses due to the change in the fiscal year and not recognized in the eight months ended December 31, 2001, and other non-recurring expenses related to employee training expenses, insurance and administrative costs.

Interest Expense.    Net interest expense for 2002 was $0.7 million compared to $0.8 million for the corresponding period of 2001. As of December 31, 2002 and April 30, 2002, total amounts due for bank lines of credit and term loans were $14.2 million and $19.4 million, respectively.

Provision For Income Taxes.    During 2002 we established a $24.0 million valuation allowance for deferred tax assets, which affected our estimated effective annual tax rate of 1,111.7% for the transition period ended December 31, 2002. We believe it is more likely than not that a portion of our deferred tax asset will not be realized and established a reserve for those assets that are not likely to be utilized in the next three years, notwithstanding that some of these may have longer lives under applicable tax laws. Federal net operating loss carryforwards of $66.5 million, as of December 31, 2002, begin to expire in 2021. We have federal and state research and development credit carryforwards aggregating approximately $9.3 million. Federal research and development credits totaling $4.9 million as of December 31, 2002 begin to expire in 2009. State research and development credits of $4.4 million have no expiration. As of December 31, 2002, the deferred tax asset, net of the $24.0 million reserve, was $9.4 million. We believe that, based on our history of prior operating earnings, our completed spin-off of Quantum and our expectations for the future, our operating income will more likely than not be sufficient to recognize fully the net deferred tax assets within the next three years.

Discontinued Operation.    We completed the spin-off of Quantum on July 23, 2002. The loss from discontinued operation during the transition period ended December 31, 2002 was $5.2 million or $3.1 million, net of a $2.1 million tax benefit. For the same period ended December 31, 2001, the loss from discontinued operation was approximately $28.7 million or $17.2 million, net of a $11.5 million tax benefit.

Years Ended April 30, 2002 and 2001

Net revenues and operating income for our reporting segments for the twelve-month period ended April 30, 2001 and 2002 are as follows (in thousands):

	Revenues						Operating Income/(Loss)
	Fiscal Year Ended April 30,						Fiscal Year Ended April 30,

Total	$	80,539		$	67,676		$	6,610		$	(2,399	)

(1) Represents corporate expenses not allocated to any operating segments

Net revenue decreased $12.8 million, or 15.9%, to $67.7 million in the twelve-month period ended April 30, 2002 from $80.5 million in the twelve-month period ended April 30, 2001. This decrease was primarily due to the decline in sales of conversion kits and components to the material handling market, which were attributable to unfavorable economic conditions.

The following table sets forth our product revenues by application across all reporting segments:

	Revenues
	Fiscal Year Ended April 30,
	2001		2002
Industrial	$	54,114	$	43,081
Transportation		26,425		24,595
Total	$	80,539	$	67,676

During fiscal years 2001 and 2002, our revenue was generated in the following geographic regions in the following percent proportions:

	2001		2002
United States and Canada	55.0	%	44.1	%
Asia & Pacific Rim	13.0	%	9.9	%
Europe	20.2	%	27.8	%
Latin America	11.8	%	18.2	%

U.S. Operations.    Net revenues in this segment decreased $14.9 million, or 22.2%, to $52.1 million in the twelve-month period ended April 30, 2002 from $66.9 million in the twelve-month period ended April 30, 2001. Revenues were lower primarily due to the decline in sales of our products to the material handling market. We believe this decline in sales was caused by the current economic slowdown. The increase in our large stationary engine market was largely offset by the decline in our small industrial engine market.

Gross profit in this segment decreased $8.0 million, or 35.9%, to $14.3 million in the twelve-month period ended April 30, 2002 from $22.3 million in the twelve-month period ended April 30, 2001. The decline in revenues negatively impacted gross profit by $5.0 million. The remaining $3.0 million decline in gross profit was due to product mix consisting of a higher percentage of lower margin complete engine systems sales and lower margin sales to our foreign subsidiaries.

24

Operating income in this segment decreased $7.7 million, or 69.4%, to $3.4 million in the twelve-month period ended April 30, 2002 from $11.1 million in the twelve-month period ended April 30, 2001. This decrease was due to lower gross profits offset by a net $0.3 million reduction in operating expenses.

International Operations.    Net revenues in this segment increased by $1.7 million, or 5.5%, to $32.8 million in the twelve-month period ended April 30, 2002 from $31.1 million in the twelve-month period ended April 30, 2001. In the twelve-month period ended April 30, 2002, net revenues increased $4.1 million at our Mexico subsidiary, $0.7 million in Asia, and $0.4 million at our European subsidiary. These increases were partially offset by decreases of $2.5 million at our Australian subsidiary and $1.0 million at our Japan subsidiary. In the twelve-month period ended April 30, 2002, revenues for our International Operations segment would have increased an additional $0.4 million if not for the strengthening of the U.S. Dollar. A strong U.S. Dollar has a negative effect on the conversion of foreign currency denominated sales.

Gross profit in this segment decreased $0.6 million, or 6.2%, to $8.3 million in the twelve-month period ended April 30, 2002 from $8.9 million in the twelve-month period ended April 30, 2001. Gross profit declined $1.1 million due to lower margins due to differences in product mix, which was partially offset by a $0.5 million increase in gross profit due to higher revenues.

Operating income for this segment decreased $0.8 million, or 57.1%, to $0.6 million in the twelve-month period ended April 30, 2002 from $1.4 million in the twelve-month period ended April 30, 2001 as all foreign subsidiaries except Mexico experienced lower operating income. This was primarily a result of lower gross margins due to the higher cost of U.S. goods purchased with their weakening local currencies. Additionally, we added marketing and technical personnel to support new and expanding markets in Asia, which resulted in increased operating expenses in the twelve-month period ended April 30, 2002 as compared to the twelve-month period ended April 30, 2001.

Corporate Expenses.    Corporate expenses consists of general and administrative expenses at the corporate level to support our operating segments in areas such as executive management, finance, human resources, management information systems, legal services and investor relations. Additionally, amortization of goodwill and other intangible assets was recorded as a corporate expense. Corporate expenses increased $0.9 million, or 15.3%, to $6.8 million in the twelve-month period ended April 30, 2002 from $5.9 million in the twelve-month period ended April 30, 2001. During the twelve month period ended April 30, 2002, the increase in corporate expenses were attributable to $1.2 million in legal fees and consulting services primarily related to Quantum spin-off costs and our From S-3 filing in connection with a follow-on equity offering, which was withdrawn on September 20, 2001.

Interest Expense (Net).    Net interest expense increased by $0.8 million, to $0.9 million, in the twelve-month period ended April 30, 2002 from $0.1 million in the twelve-month period ended April 30, 2001. The increase was primarily due to a higher outstanding balance from our line of credit with Bank of America, as compared to the interest income generated from the proceeds of the July 2000 equity offering in the first quarter of the prior fiscal year.

Provision for Income Taxes.    The estimated effective annual tax benefit rate of 40% for the twelve-month period ended April 30, 2002 was less than the tax benefit rate of 41% in the twelve-month period ended April 30, 2001. The effective tax benefit rate represents the federal statutory income tax rate, state income taxes and foreign income taxes increased by research and development credits. For the twelve-month period ended April 30, 2002, including the effects of the discontinued operation, we have incurred a $45.5 million loss before income taxes and minority interest. Also, we had federal and state research and development credit carryforwards aggregating approximately $9.2 million. Federal research and development credits totaling $5.0 million begin to expire in 2009. State research and development credits of $4.2 million have no expiration date. As of April 30, 2002, the net deferred tax asset was $31.9 million.

25

Discontinued Operation.    Prior to the completed spin-off of Quantum on July 23, 2002, the loss from discontinued operation during the fiscal year ended April 31, 2002 was $41.7 million, or $25.0 million net of a $16.7 million tax benefit. For the same period ended April 30, 2001, the loss from discontinued operation was approximately $28.6 million, or $16.8 million net of a $11.8 million tax benefit.

Liquidity and Capital Resources

Our ongoing operations are funded by cash generated from operations, debt financings and sales of our equity securities. In addition, these sources of cash provide for capital expenditures and research and development, as well as to invest in and operate our existing operations and prospective new lines of business.

As of December 31, 2003, our cash and cash equivalents totaled $9.5 million, compared to cash and cash equivalents of $2.0 million at December 31, 2002. On July 22, 2003 we refinanced our debt to retire our $11.3 million debt to Bank of America, to finance the $7.0 million deferred payment to complete the 50% acquisition of B.R.C. Societá Responsabilitá Limitata (“BRC”), and to provide working capital. The debt restructuring consisted of two new loans. First, we entered into a senior subordinated secured promissory note and a related securities purchase agreement with Bison Capital Structured Equity Partners, LLC (“Bison”) for an aggregate borrowing of $20.0 million, with net proceeds of $17.3 million, and we issued to an affiliate of Bison warrants to purchase up to 500,000 shares of our common stock. The Bison loan has a nominal interest rate of 11.25%, subject to certain adjustments, and matures on July 22, 2007. Interest on the Bison loan is payable monthly in arrears. During periods in which an event of default exists under the Bison loan agreement, the interest rate increases at a rate of 0.50% per month up to a maximum of 6 months or 3%, and in certain circumstances, interest payments during an event of default can be capitalized, or added to the principal amount outstanding. At the same time, we entered into a revolving loan and security agreement and a related secured promissory note with LaSalle Business Credit, LLC (“LaSalle”). The LaSalle loan has a maximum borrowing limit of $12.0 million, with availability based upon a percentage of eligible inventory and eligible accounts receivable, and has an adjustable interest rate of 1% above LaSalle’s prime rate as announced from time to time and matures on July 22, 2006. Interest on the LaSalle loan is payable monthly in arrears. During periods in which an event of default exists under the LaSalle loan agreement, the interest rate increases to 2% above LaSalle’s prime rate. The Bison and LaSalle loans contain cross-default provisions such that an event of default existing under one loan generally constitutes an event of default under the other. As of December 31, 2003, our borrowing under the line of credit was approximately $5.2 million with approximately $1.6 million unused and available under the line. On March 12, 2004, we received an amendment to the LaSalle loan agreement to expand the eligible accounts receivable, resulting in an additional $2.6 million of available additional borrowing under this loan. On December 19, 2003 we sold 1,500,000 shares of common stock to certain institutional investors at $6.40 per share, yielding net proceeds of approximately $9.0 million after discounts and commissions. The offering was conducted as a private placement under Section 4(2) of the Securities Act and Rule 506 promulgated thereunder. The proceeds of this offering were used to retire short-term debt and for working capital.

Our subsidiary in Japan has a ¥64 million (US$0.6 million at December 31, 2003) short-term loan facility with the Hong Kong and Shanghai Banking Corporation Ltd., Osaka Branch. At December 31, 2003, a balance of $0.6 million was outstanding. Our subsidiary in the Netherlands has a secured €2.3 million ($2.9 million) revocable credit facility with Fortis Bank. At December 31, 2003 there were no borrowings on this facility.

On October 3, 2002, we entered into an option agreement with the equity holders of BRC. Under the option agreement, we obtained the right to purchase from those equity holders 50% of the outstanding equity interest of BRC for approximately $23.8 million, which included the issuance of approximately 2.3 million shares of Company common stock (which the parties acknowledged and agreed were valued at $10.0 million). We announced on May 8, 2003 that we had exercised the option and that the purchase of 50% of BRC was completed pending a $7.0 million payment that represented a deferred portion of the purchase price due on September 30, 2003. On July 22, 2003, immediately after the refinancing of our debt as discussed above, we paid the deferred payment of $7.0 million to the equity holders of BRC completing the acquisition of the 50% equity interest in

26

BRC. As of December 31, 2003, we had incurred acquisition costs of approximately $24.8 million, which are shown on the consolidated balance sheet as part of investment in affiliates. The corresponding costs incurred as of December 31, 2002 totaled $12.6 million. We use the equity method of accounting to recognize the investment in and the results of BRC in our consolidated financial results.

As a result of the refinancing of the Bank of America debt and the acquisition of our 50% equity interest in BRC, we have assumed additional long-term debt, which has increased our financial leverage. Interest costs and related charges since July 2003 have been higher than in prior years and will continue to be a significant use of funds. The LaSalle and Bison notes have loan terms of three and four years, respectively. Under the Bison agreement, we are obligated to pay off the note in July 2007 in the amount of $20.0 million. Under the LaSalle agreement, which has a maturity date of July 2006, we are obligated to repay the balance owed at that time under the revolving line of credit, not to exceed $12.0 million. At December 31, 2003 the Company was in default under terms of the LaSalle agreement in failure to maintain minimum consolidated EBITDA of $4,000,000, to maintain a consolidated fixed charge coverage ratio of not less than 0.25:1.00, and to maintain a consolidated leverage ratio not to exceed 8.45:1.00. LaSalle has waived these financial covenant non-compliance conditions at December 31, 2003. The Company was also in default under terms of the Bison agreement in failure to maintain minimum consolidated EBITDA of $3,500,000 and minimum consolidated leverage ratio not to exceed 8.50:1.00. Bison has waived these covenant non-compliance conditions at December 31, 2003. The events of default under these loans will cause our applicable interest rates to increase as long as the circumstances continue unless we are successful in negotiating amendments to these covenants. The LaSalle loan increases the interest rate to prime plus 2%, which will increase our interest expense and our cash outflows by approximately $25,000 per quarter. Under the Bison loan, the applicable interest rate increases by 0.5% per month up to a maximum of 3% or six months. We expect that the increase in the Bison interest rate will increase our interest expense by approximately $150,000 during the first quarter of 2004, although in certain circumstances we are permitted to capitalize those interest payments by adding them to the principal balance outstanding under the Bison loan. We also are seeking to revise our financial covenants in both loans to reflect more conservative estimates of future financial performance. However, we cannot be assured that the lenders will agree to amend our financial covenants or grant further or continuing waivers in the future. If we cannot obtain the necessary waivers or amendments, or return to compliance with these and all other loan covenants, our lenders may accelerate our debt, foreclose on our assets, or take other legal actions against us which, alone or in the aggregate, may have a material adverse effect on our business. During 2003, we received proceeds of approximately $4.1 million in bridge loans and $8.0 million in loan commitments. As of December 31, 2003, we had repaid all of the bridge loans and the loan commitment expired without us exercising our option to borrow under its terms.

Our ratio of current assets to current liabilities was 2.0:1.0 at December 31, 2003 as compared to 1.5:1.0 at December 31, 2002. During this same period our total working capital increased by $10.9 million from $11.2 million at December 31, 2002 to $22.1 million at December 31, 2003. Current assets increased by $8.9 million due primarily to the stock offering in December 2003 yielding net proceeds of $9.0 million and current liabilities decreased by $2.0 million due primarily to payment of the Bank of America debt that was classified as a current liability at December 31, 2002.

Net cash provided by operating activities for fiscal 2003 was $0.8 million, compared to cash provided by operations for the eight months ended December 31, 2002 of $1.7 million. The decline in cash flow was attributed to the launch of the Spectrum product line during 2003, which required working capital investments in accounts receivable and inventory in the amounts of $2.4 million and $0.6 million, respectively. Increases in accounts payable and accrued expenses during 2003 resulted in a $6.2 million source of cash, which provided the necessary working capital to fund the Spectrum launch and to fund the loss from continuing operations of approximately $2.1 million after the effect of non-cash items totaling $4.8 million. In the eight months ended December 31, 2002, cash flow from operating activities benefited from reductions in inventory and accounts receivables totaling $2.8 million attributed primarily to the 19% decline in revenues during the three months ended December 31, 2002.

27

Net cash used in investing activities for the fiscal year ended December 31, 2003 was $15.4 million, an increase of $11.2 million from $4.2 million for the eight months ended December 31, 2002. This increase is due primarily to costs related to the 50% acquisition of BRC.

Net cash provided by financing activities for the fiscal year ended December 31, 2003 was $20.7 million or an increase of $9.2 million from $11.5 million for the eight months ended December 31, 2002. During December 2003, we raised approximately $9.0 million in net proceeds from the issuance of 1.5 million shares of common stock to institutional investors.

For the fiscal year ended December 31, 2003, cash provided by continuing operations totaled $6.1 million or a decrease of $2.9 million from the eight months ended December 31, 2002.

At December 31, 2003 the Company had received waivers from its two lenders, LaSalle and Bison, for covenant non-compliance conditions at December 31, 2003. In addition: a) Bison granted the Company a modified EBITDA calculation for 2004 and a further waiver in maintaining its Term Loan status as a long term liability throughout 2004; b) LaSalle granted the Company a favorable amendment on March 12, 2004 which resulted in additional borrowing line capacity of $2.6 million; and c) we believe that LaSalle will work with the Company to amend its credit arrangement for the remainder of its term. Accordingly, we believe that the Company has sufficient resources to meet its current financial obligations and finance its operations over the next twelve months.

Should we be unable to obtain waivers or amendments, the Company believes that its current cash balances, available cash drawn from its subsidiaries, other financing alternatives, our history of being able to raise equity, and our ability to obtain bridge loans will result in adequate liquidity to continue operations through December 31, 2004.

Derivative Financial Instruments

We have used derivative financial instruments for the purpose of reducing our exposure to adverse fluctuations in interest and foreign exchange rates. While these hedging instruments are subject to fluctuations in value, such fluctuations are generally offset by the value of the underlying exposures being hedged. We are not a party to leveraged derivatives and do not hold or issue financial instruments for speculative purposes. As of December 31, 2003, we did not utilize any derivative financial instruments.

Foreign Currency Management.    The results and financial condition of our international operations are affected by changes in exchange rates between certain foreign currencies and the U.S. Dollar. Our exposure to fluctuations in currency exchange rates has increased as a result of the growth of our international subsidiaries. The functional currency for all of our international subsidiaries is the local currency of the subsidiary. An increase in the value of the U.S. Dollar increases the costs incurred by our subsidiaries because most of our international subsidiaries’ inventory purchases are U.S. Dollar denominated. We monitor this risk and attempt to minimize the exposure through forward currency contracts and the management of cash disbursements in local currencies. At December 31, 2003, we have a single foreign exchange forward contract of approximately $0.5 million in which gains and losses are recognized in the statement of operations as the fair value of the contracts fluctuates. We seek to manage our foreign currency economic risk by minimizing our U.S. Dollar investment in foreign operations using foreign currency term-loans to finance the operations of our foreign subsidiaries.

Recent Accounting Pronouncements

In January 2003, the Financial Accounting Standards Board (“FASB”) issued Interpretation No. 46, Consolidation of Variable Interest Entities, an Interpretation of Accounting Research Bulletin No. 51, (“FIN 46”). FIN 46 introduces a new consolidation model, the variable interests model, which determines control (and consolidation) based on potential variability in gains and losses of the entity being evaluated for consolidation. The requirements for FIN 46, including its disclosures, apply immediately.

FIN 46 provides guidance for determining whether an entity qualifies as a variable interest entity (“VIE”) by considering, among other considerations, whether the entity lacks sufficient equity or its equity holders lack adequate decision-making ability. If the entity does not qualify as a VIE, then the consolidation criteria is based on previously established accounting standards. Qualifying VIEs are covered by FIN 46 and are individually evaluated for consolidation based on their variable interests. FIN 46 requires consideration and estimates of a significant number of possible future outcomes of the VIE as well as the probability of each outcome occurring. Based on the allocation of possible outcomes, a calculation is performed to determine which party, if any, has a majority of potential negative outcomes (expected losses) or a majority of the potential positive outcomes (expected residual returns), with an emphasis on negative outcomes. That party, if any, is the primary beneficiary and is required to consolidate the VIE. We have evaluated the potential impact of FIN 46 as of December 31, 2003 and have concluded that there was no impact on our consolidated financial statements.

We adopted the new rules on accounting for goodwill and other intangible assets beginning with the transition period ended December 31, 2002. Application of the nonamortization provisions of the Statement resulted in an increase in net income on an annual basis of approximately $0.4 million ($.03 per share). We performed the first of the required impairment tests of goodwill and indefinite lived intangible assets effective May 1, 2002 and determined that there was no impact on the Company’s financial position during the period ended July 31, 2002. We also conducted the goodwill impairment tests as of December 31, 2002 and 2003 and similarly determined that there were no impacts on our financial position.

BUSINESS

Overview

We design, manufacture and supply advanced systems that store gaseous fuels and monitor and control the pressure and flow of those fuels for use in internal combustion engines. Our components and systems enable internal combustion engines to operate on natural gas or propane. Our products improve efficiency, enhance power output, and reduce emissions by electronically sensing and regulating the proper proportion of fuel and air required by the internal combustion engine. Additionally, we have extensive engineering, design and systems integration experience with our customers’ requirements for product performance, durability and physical configuration. Based on over 45 years of technology development and expertise in producing cost-effective, safe and durable fuel technology systems, we believe we are positioned to provide enabling products and technologies in the rapidly expanding alternative fuel industry.

Our customers use our components and systems on engines ranging from one to 4,000 horsepower. We provide gaseous fuel components and systems to the transportation market and the industrial market, which includes the material handling and stationary and portable power generation markets.

A number of original equipment manufacturers, or OEMs, in the automotive, industrial and power generation industries, who are our customers, are developing alternative clean power systems using clean burning gaseous fuels, which decrease fuel costs, lessen dependence on crude oil and reduce harmful emissions of internal combustion engines. We offer the following products, kits and systems to these customers:

• systems integration—services to integrate the gaseous fuel storage, fuel delivery and/or electronic control components and sub-systems to meet OEM and aftermarket requirements.

• fuel delivery—pressure regulators, fuel injectors, flow control valves, and other components and systems designed to control the pressure, flow and/or metering of gaseous fuels;

• electronic controls—solid-state components and proprietary software that monitor and optimize fuel pressure and flow to meet manufacturers’ engine requirements; and

• gaseous fueled internal combustion engines—engines manufactured by OEMs that are integrated with our fuel delivery and electronic control system.

We have been producing and selling gaseous fuel systems and components for over 45 years. We sell these systems and components directly to end users, OEMs and the aftermarket through more than 400 distributors and dealers worldwide.

We were incorporated in Delaware in 1985 after having provided automotive and alternative fuel solutions in a variety of organizational structures since 1959.

Alternative Fuel Industry

Overview.

We focus on the alternative fuel industry. Three independent market factors—economics, energy independence and environmental concerns—are driving the development of alternative fuel industry technology and markets. We believe the historic price differential between propane or natural gas and gasoline drives the economics of the alternative fuel market. The price of clean fuels such as natural gas or propane are typically 40% to 60% that of traditional liquid fuels such as gasoline. By converting an internal combustion engine to run on propane or natural gas customers can capitalize on the fuel price differential and reduce harmful vehicle emissions emitted from liquid fueled engines.

End users typically can recoup the cost of the conversion within six to eighteen months, depending on the fuel cost disparity prevailing at the time. Transportation companies in various countries, including Australia, Mexico, India and China, are taking advantage of these economics.

31

Among our most active customers are taxi companies, transit and shuttle bus companies, and companies with extensive delivery fleets such as Coca Cola, Frito-Lay, Pepsi Cola and United Parcel Service. Small and large industrial engine users in the power generation market capitalize on the cost benefits of using alternative fuels and their low-pollutant capabilities. For example, forklift users often operate equipment indoors where toxic emissions are a concern. In all these situations, it is relatively easy to establish centralized fueling stations. Because of the global price differential in favor of gaseous fuels compared to gasoline, their availability in third-world markets and their lower pollutants, the alternative fuel industry market potential is growing rapidly. Approximately 57% of our revenues are derived from sales outside the United States, of which Mexico accounted for 16% of sales and Europe accounted for 29% of sales for the fiscal year ended December 31, 2003.

In addition to economics, energy independence is a significant driver for the alternative fuel market. Many countries have significant natural gas reserves and seek to use alternative fuels to reduce their dependence on imported oil and reduce their unfavorable balance of payments. Natural gas is generally consumed domestically since it is difficult to transport internationally in a gaseous state and liquefying natural gas tends to be costly. Implementing OEM alternative fuel vehicles that operate on natural gas or propane can lessen the demand for gasoline. For example, the Egyptian and Chinese governments realized that rather than relying solely on petroleum for its transportation needs, each could use natural gas in vehicles to free some of its oil production for export.

Governmental emission regulations, which support the use of clean burning alternative fuels, are also expanding the alternative fuel industry growth. The negative environmental impact associated with liquid fossil fuels further increases the demand for systems that use clean burning fuels. Internal combustion engines are a major source of air pollution, which has led to increased government regulation and oversight on vehicle and industrial engine emissions. The U.S. Department of Energy estimates that conventional motor vehicles fueled with natural gas emit 80% less carbon monoxide and nitrogen oxide than vehicles fueled by reformulated gasoline. Most major international cities are experiencing significant pollution from gasoline and diesel emissions. These cities also have the largest concentrations of fleet operators, and many of these cities are taking steps to reduce emissions, typically by implementing natural gas or propane-fueled vehicles. For example, in Mexico City, Milan and Rome, Italy the governments have taken steps such as prohibiting the use of certain vehicles on designated days of the week.

In the United States, legislative and administrative policies such as the Comprehensive National Energy Strategy, the Clean Air Act Amendments of 1990; the Energy Policy Act of 1992; and the Organization for Economic Cooperation and Development (OECD) Environmental Committee’s Report on Environmentally Sustainable Transport provide goals for energy efficiency and coupled with the Environmental Protection Agency and the California Air Resource Board’s Large Spark Ignited Off-Highway Emission regulation for industrial equipment afford strict emission standards and promote the development and implementation of alternative fuels and related technologies. All states, including California, Massachusetts, New York and Texas, have also adopted legislation targeted at reducing harmful emissions from motor vehicles, industrial equipment, industry and consumer products. In addition, several countries, including Argentina, Canada, China, Colombia, Egypt, France, Germany, Greece, India, Italy, Mexico, Russia and the United Kingdom, have enacted air pollution regulations or programs favoring the use of alternative fuels, including gaseous fuels such as low-carbon content propane and natural gas.

Markets.

IMPCO is directly involved in three key-energy use market segments (transportation, industrial equipment and power generation equipment), which have seen growth in the use of clean-burning gaseous fuels in association with other lower-emission fuel-components.

Transportation.    According to the most recent statistics from the World LP Gas Association, the International Association for Natural Gas Vehicles (IANGV) and the European Natural Gas Association, there are over 5.7 million gaseous fuel vehicles in use worldwide: either for personal mobility, fleet conveyance or

32

public transportation. As the world’s vehicle population increases from 800 million to over 1.3 billion by 2020, most growth will occur in developing countries within Asia, North Africa, and areas of the Middle East. These regions currently have the lowest ratio of vehicles per one thousand people, and are slated to grow rapidly over the next ten years as economic improvements stimulate personal vehicle ownership.

The Energy Information Administration of the U.S. Department of Energy, the World Bank, the Office of Economic and Community Development, the fifteen countries of the European Union (EU15) and the Asian Development Bank suggests that interest in expanding the use of alternative fuel vehicles is mounting in many parts of the developed and developing world. Growth projections, reported by the Energy Information Administration and the IANGV in comparison with current data available from the European Natural Gas Vehicle Association, indicate that over two million additional alternative fuel vehicles will be introduced worldwide by 2010. In Europe, alternative fuel vehicles have rapidly penetrated the transportation market. The European Union’s four largest natural gas-consuming members, the United Kingdom, Germany, France, and Italy, all have introduced incentives for gaseous-fueled vehicles. The European Union has established a target to replace 20% of their liquid fueled vehicles with gaseous fuels by 2020. The Mexican Regulatory Commission of Energy estimates that Mexico will be able to increase the use of natural gas vehicles from 2,000 in 2000 to 100,000 by 2008.

The Asia region is emerging as a significant growth market for alternative fuel vehicles. China, already the world’s second-largest energy consumer, will continue to grow in importance on world energy markets as many forecasts suggest that strong economic growth will drive up demand.

Industrial.    Equipment such as forklifts, aerial platforms, sweepers, turf equipment, light-duty construction equipment, mobile wood-processing equipment and other mobile industrial equipment have long been the workhorses of developed countries, and are a significant portion of IMPCO’s global activities. With developed countries such as the United States and the EU15 seeking a broader incorporation of emission sources in an attempt to further reduce air pollution, many countries have and will legislate emission standards for this type of equipment. In the United States, the Environmental Protection Agency has enacted emission regulations for industrial off-highway equipment starting in 2004 that follows suit with California’s Large Spark Ignited mobile off-highway emission regulation initiated in 2001.

In North America alone there are more than 100,000 pieces of industrial off-highway equipment manufactured each year that use internal combustion engines. With new emission regulations being imposed, these OEMs will require advanced technologies that permit the use of gaseous fuels in order to satisfy not only the regulation, but also the customers’ requirements for durability, performance and reliability. IMPCO has developed and is currently supplying a series of advanced technology fuel systems to the industrial OEM market under the brand name Spectrum. IMPCO and its industrial brands focus on serving over 70% of the market with fuel systems, services and emission certified engine packages.

Power Generation.    The World Energy Outlook 2002 projects the global primary energy demand will increase by 1.7% per year from 2000 to 2030, reaching 15.3 billion tons of oil equivalent. Even though the earth’s energy resources are adequate to meet this demand, the amount of investment that will be needed for these resources to be exploited is significantly higher than has occurred in the past. For example, investment needs in the power sector are expected to be almost three times larger over the coming three decades than over the last three. Investment in the oil industry will also have to rise sharply, as demand rises and the surplus capacity in crude oil production and refining that has characterized the industry since the 1970s is used up. Gaseous fuels such as propane and natural gas have significant reserves available worldwide which are less costly to refine compared to crude oil and have historically been less expensive than liquid fuels. Countries like China, for example, are actively developing their infrastructure to utilize their natural gas reserves rather than import liquid fuels.

Competitive Advantages

We believe we can extend our technological leadership position in the alternative fuel industry based on our history of success in the designing, manufacturing and commercializing advanced fuel delivery systems and components, our relationships with leading companies in transportation and industrial markets, our financial commitment to research and development and our proven ability to develop and commercialize new products. We believe our competitive strengths include:

Industry Leader.    We have derived a technology and product leadership position from the broad application and integration of our technologies and enabling systems into the established and expanding alternative fuel industry. Over the past nine years we have invested approximately $130 million in research and development. This investment, coupled with our history and experience in this industry, has provided us with a strong technology base for new product innovation for internal combustion engines, particularly in our industrial markets. Additionally, we believe our acquisition of 50% of BRC will expand our technology and product leadership position. BRC has been developing, manufacturing and marketing alternative gaseous fuel products and systems for automobiles for more than twenty years.

Proven Manufacturing Methods.    We have more than four decades of experience in the manufacture, development and integration of alternative fuel technologies and products. We currently maintain manufacturing and production facilities in the United States, Europe, Mexico and Australia, which produce a broad range of products and services, including components, systems and specialty vehicle assembly. Our U.S., Australian and European facilities have achieved ISO-9000 or QS-9000 certification. QS-9000 is the common supplier quality standard for Chrysler Corporation, Ford Motor Company and General Motors. QS-9000 applies to suppliers of production materials, production and service parts, heat-treating, painting and plating and other finishing services. ISO-9000 is a set of three individual, but related, international standards on quality management and quality assurance. These standards were developed to document effectively the quality controls necessary to maintain efficient systems. Our 50% acquisition of BRC further expands our ability to manufacture and produce products in Europe and South America. Additionally, BRC provides a broader manufacturing capability such as machining centers and electronic circuit board production to enable us to more readily realize cost reductions as opposed to purchasing from outside vendors.

Strong OEM Customer Relationships.    We currently sell products to more than 100 OEM customers in domestic and international alternative fuel markets. To date, we have sold over four million fuel systems or sub-systems globally to our customers. We believe that the successful historic use of our products and our reputation as a leader in our industry provides a strong competitive position.

Established Systems Integration Expertise.    As more OEMs seek to reduce costs by outsourcing key tasks and reducing the number of suppliers, we have focused increasingly on capturing additional revenue opportunities by expanding our systems integration capabilities. In 1998, we established our Industrial Engine Systems business in Sterling Heights, Michigan, which provides systems integration of our low-emission products for engines that are subsequently sold to industrial OEMs. We believe that our systems integration expertise, together with our proprietary and patented technologies, give us a significant advantage in the alternative fuel markets.

Positioned for Global Growth.    With ten foreign facilities and over 400 distributors and dealers in more than 30 countries outside the United States, we believe that we are positioned to capitalize on global growth opportunities. We believe that the alternative fuel markets will grow dramatically internationally, particularly in China, India, Japan, Mexico and Southeast Asia, because of the existing urban pollution problems and economics that favor alternative fuels versus gasoline. Our acquisition of the BRC equity interest strengthens our global position by adding an additional 200 distributors and dealers in all 15 European nations, as well as ten Eastern European countries, and a number of developing countries including Brazil, Argentina, Chile, Australia, India, China, Thailand and South Korea.

Business Strategy

We believe that the successful execution of the following strategic objectives will enable us to maintain and expand our leadership position in the advanced fuel technologies industry.

Capitalize on our Strong Technology Leadership Position.    We are a leading developer and manufacturer of fuel metering and electronic control systems for the alternative fuel industry. Management believes our position results from our current technology advantage and our investment in research and development. Our investment has permitted us to develop and supply new technology and products to our target markets, which are transitioning to gaseous-fueled internal combustion engines, and management believes these trends will continue to grow as liquid fossil fuels become increasingly scarce and expensive to develop. We also plan to develop new technologies and expand our product and system integration capabilities to an increasingly larger and more diversified customer base. Our 50% acquisition of BRC strengthens and broadens our leadership position.

Focus on Advanced Fuel Technologies and Products.    We intend to focus on advanced electronic and fuel metering technologies and products. We plan to continue our research and product development in fuel delivery and electronic control systems for alternative fuels. We actively seek to establish joint development programs and strategic alliances with the major engine designers, manufacturers and industry leaders in these markets.

Develop and Expand Key Industry Relationships.    We plan to utilize the successful technical and business relationships and reputation we have established worldwide with major industry leaders using alternative fuel products to enable us to establish and maintain strategic alliances, joint product development programs and joint ventures with these companies in our target markets. We will concentrate our efforts on broadening our OEM relationships in an effort to establish strong top-tier supplier positions based on our belief that OEMs will drive industry growth in the alternative fuel industry. The 50% purchase of BRC expands our OEM relations with countries, particularly in Latin America, Europe and Asia.

Expand and Broaden Systems Integration Expertise.    We expect to continue to broaden our capabilities to provide integration, testing, validation and manufacturing of our products and systems into the transportation, material handling, stationary and portable power generation and general industrial markets. As more OEMs seek to reduce costs and shorten time to market by outsourcing key tasks and reducing numbers of suppliers, we are focused increasingly on capturing additional revenue opportunities by expanding into value-added services, such as systems integration. For example, we have established an industrial systems unit in Michigan to integrate our products into engines that will be sold to industrial OEMs, who in turn will install these engines into end products.

Increase Bases of Business Operations and Distributor Network in High-Growth Global Regions.    We plan to expand our operating network in high-growth regions, such as Asia, Europe and Latin America, to take advantage of significant growth opportunities that we believe exist in those areas. We intend to capitalize on these growth opportunities through acquisitions and joint ventures, strengthening of our distributor network and developing key local business and governmental support and recognition. In addition, our recent joint venture agreements with Minda Industries Limited India and with CNGC, a subsidiary of China National Petroleum Co., expand our presence in the Indian and Chinese markets, respectively. Additionally, we are developing working relationships with several foreign governments. We believe that working with local governments and establishing joint ventures with local business leaders is essential to expanding into international markets. For example, our discussions with government officials have led to our involvement in developing regulations in Mexico. Management expects that our acquisition of BRC equity interest will further expand our presence in the global transportation market.

Expand our Global Manufacturing Operations.    We plan to expand our current QS-9000 manufacturing operations in the United States and Mexico by establishing manufacturing sites in low-cost locations with a continued focus on quality, timely delivery and operating efficiency. In addition, we anticipate that the manufacturing strengths of BRC, coupled with the additional product volume will result in productivity improvements.

Our customers include some of the world’s largest OEMs and engine manufacturers, including Ashok Leyland, Boss Manufacturing, Caterpillar, Clark, Cummins, Daewoo, Detroit Diesel, Ford Australia, GM Holden, Kohler, Komatsu, Mazda, Mitsubishi, Onan, Still and Toyota.

We are working with a number of these customers to address their future product and application requirements as they integrate more advanced, certified gaseous fuel systems and engines into their business strategies. Additionally, we continually survey and evaluate the benefits of joint ventures, acquisitions and strategic alliances with our customers and other participants in the alternative fuel industry to strengthen our global business position.

We have focused our strategic alliances on our marketing strategy and/or on our development strategy. Our marketing strategy seeks to expand the distribution channels and OEM customer base for our gaseous fuel system technologies. Our development strategy is to advance the state of technology and its application.

Quantum Collaboration.    Our three-year agreement with Quantum provides that we will collaborate with Quantum to identify and conduct research and development programs of mutual interest. As part of those research and development activities, we may develop technology and products separately or jointly with Quantum. The agreement also allows us to acquire and sell into our alternative fuel markets Quantum’s advanced technology products, including CNG storage tanks, fuel injectors, in-tank regulators and other products, for use in automotive, bus and truck and industrial aftermarket applications and in the bus and truck and industrial OEM markets. For jointly developed products, we and Quantum will jointly own any patent or other intellectual property rights and will issue royalty-free cross licenses covering our respective markets. For separately developed products, each party will grant the other a right to sell the affected products in their respective markets. The developing party will retain sole intellectual property ownership.

We believe that the ongoing Quantum alliance will expedite the commercialization and integration of advanced gaseous storage and handling systems and products into our broader global alternative fuel markets, including automotive after-market, material handling, portable and stationary internal combustion engine-based power generation, and general industrial markets. In addition, we believe that the spin-off will enable IMPCO to optimize its growth strategies as a separate, stand-alone entity, based on its capitalization and financing requirements, acquisition strategies, working capital requirements, projected cash flows from operations and credit ratings.

Management plans to establish similar relationships with leading manufacturers by using our systems integration capabilities and our leading technology position in gaseous fuel products and systems.

Sales and Distribution

We sell products through a worldwide network encompassing more than 400 distributors and dealers in over 30 countries and through a sales force that develops sales with OEMs and large end-users. We focus on two markets: 1) the industrial market which includes material handling OEMs and aftermarket and stationary and portable power generation OEMs and aftermarket, and 2) the transportation OEM and aftermarket. Of these markets, we believe that the greatest potential for immediate growth is in the Latin America and Asia Pacific regions in the transportation OEM and aftermarket and in North America in the industrial OEM and aftermarket.

For the fiscal year ended December 31, 2003, sales to distributors (including company-owned distributors) accounted for 45% of our net revenue and sales to OEM customers accounted for approximately 55% of our net

38

revenue. During the transition period beginning May 1, 2002 and ending December 31, 2002, sales to distributors accounted for 56% of our net revenue and sales to OEM customers accounted for 44% of net revenues. This change is due to increased revenues to OEM domestic customers.

Our company-owned distributors are included in our International Operations segment and consist of our subsidiaries located in Europe, Australia, Mexico, Japan, India and China, which are responsible for sales, application and market development and technical service. Additionally, these subsidiaries provide sales support, application development and technical support to aftermarket and OEM customers.

Manufacturing

We manufacture and assemble products at our facilities in Cerritos, California, Sterling Heights, Michigan and at our international facilities. Current manufacturing operations consist primarily of mechanical assembly and light machining. We rely on outside suppliers for parts and components and obtain components for products from a variety of domestic and foreign automotive and electronics suppliers, die casters, stamping operations, specialized diaphragm manufacturers and machine shops. For the fiscal year ended December 31, 2003, ten suppliers accounted for approximately 71% of our raw material purchases. During our fiscal years 2001 and 2002, the transition period ended December 31, 2002, and the fiscal year ended December 31, 2003, General Motors Corporation, and affiliates of General Motors, accounted for approximately 29%, 9%, 12% and 33% respectively, of purchases. . During our fiscal years 2001 and 2002, the transition period ended December 31, 2002, and the fiscal year ended December 31, 2003, Rangers Die Casting Company accounted for approximately 12%, 8%, 8% and 7%, respectively, of purchases.

Material costs and machined die cast aluminum parts represent the major components of cost of sales. Coordination with suppliers for quality control and timely shipments is a high priority to maximize inventory management. We use a computerized material requirement planning system to schedule material flow and balance the competing demands of timely shipments, productivity and inventory management. All of our U.S. manufacturing facilities are ISO-9001 or QS-9001 certified.

Research and Development

Our research and development facility near Seattle, Washington is dedicated to the research and development of systems and products that support the use of gaseous fuels in internal combustion engines. This facility has sophisticated, state-of-the-art research laboratories, emissions control equipment, and testing equipment. Our research and development is focused on fuel delivery and electronic control systems and products for motor vehicles, engines, forklifts, stationary engines and small industrial engines.

We have the following technical capabilities:

• Electronic Control Systems.    Specialization in hardware design and selection, engine modeling, calibration and software design for engine and emission controls;

• Mechanical Design and Development.    Specialization in pneumatic, kinematics, hydraulic components and systems and advanced materials, structural, flow and thermal analysis;

• Advanced Catalysts.    Catalyst and emission testing;

• Component, Subsystem and Engine System Test Facilities.    Extended vibrations, shock loads and accelerations, flow simulations and pneumatic leak checks.

We believe this facility is a critical component in our ability to maintain our technological leadership position in alternative fuel enabling systems.

39

We conduct alternative fuel application development at the following facilities:

• Cerritos, California for the power generation market;

• Seattle, Washington for the transportation market and industrial markets;

• Sterling Heights, Michigan for the industrial market.

• Rijswijk, Holland for the industrial and transportation market; and

• Cheltenham, Australia for the transportation market.

These facilities encompass a total of approximately 100,000 square feet of laboratory space, and we have more than 50 employees at these facilities.

Competition

We are a leading provider of alternative fuel systems. We provide products and integrated services for all gaseous fuels in our target markets for use in all end user applications in the alternative fuel industry.

Our key competitors in gaseous fuel delivery products, accessory components and engine conversions markets include Aisan, Koltec-Necam, Landi Renzo, Lovato, OMVL and Tartarini, which together with us account for a majority of the world market for alternative fuel products and services. These competitors compete with us primarily in the transportation markets. In the future, we may face competition from traditional automotive component suppliers, such as Bosch, Delphi, Siemens and Visteon, and from motor vehicle OEMs that develop fuel systems internally.

We believe that our competitive advantage over current and future competitors is our technology leadership derived from many years of experience with alternative gaseous fuels. Our current competitors typically focus on fuel injection and individual components. We are unique in being able to offer complete integrated fuel systems based on our own advanced technologies, including gaseous fuel storage, fuel metering, and electronic controls.

Product Certification

We must obtain emission compliance certification from the Environmental Protection Agency to sell certain of our products in the United States and from the California Air Resources Board to sell certain products in California. Each car, truck or van sold in the U.S. market must be certified by the Environmental Protection Agency before it can be introduced into commerce and its products must meet component, subsystem and system level durability, emission, refueling and various idle tests. In California, both on-road and off-road vehicles have emission compliance regulation. We have also obtained international emissions compliance certification in Argentina, Australia, Brazil, Canada, Chile, Europe and Mexico.

We strive to meet stringent industry standards set by various regulatory bodies, including the Federal Motor Vehicle Safety Standards of the United States, the National Highway and Transportation Safety Administration, the National Fire Protection Association, Underwriters Laboratories and American Gas. Approvals enhance the acceptability of our products in the domestic marketplace. Many foreign countries also accept these agency approvals as satisfying the “approval for sale” requirements in their markets.

Backlog

As of March 8, 2004, our backlog for our products was $32.0 million as compared to $13.5 million on February 28, 2003. We measure backlog for our product sales from the time orders become irrevocable, which generally occurs 90 days prior to the planned delivery date. Some of our backlog may not be shipped, and revenues from such shipments may not be recognized in Fiscal 2004, or not at all.

40

Employees

As of December 31, 2003, we employed approximately 373 persons. Of these employees, our U.S. Operations employed approximately 245 and 128 were employed by our International Operations. None of our employees are represented in a collective bargaining agreement. Management considers our relations with our employees to be good.

Intellectual Property

We currently rely primarily on patent and trade secret laws to protect our intellectual property. We currently have 11 U.S. patents and 15 foreign patents issued. Our U.S. patents began expiring in October 2002 and will expire on various dates until May 2020. We do not expect the expiration of our patents to have a material affect on our revenues.

We also rely on a combination of trademark, trade secret and other intellectual property laws and various contract rights to protect our proprietary rights. However, we cannot be sure that these intellectual property rights provide sufficient protection from competition. We believe that copyright, trademark and trade secret protection are less significant than our patents and that our growth and future success will be more dependent on factors such as the knowledge, ability and experience of our personnel, new product introductions and continued emphasis on research and development. We believe that establishing and maintaining strong strategic relationships with valued customers and OEMs are the most significant factors protecting us from new competitors.

In the past, we granted options to purchase shares of Common Stock to each of the directors. Option exercise prices are the higher of (i) the average market value of the Company’s Common Stock for the 15 trading days following the date of grant and (ii) the market value of the Company’s Common Stock on the fifteenth trading day following the date of grant. Options are not assignable and vest cumulatively at the rate of 25% annually, beginning on the first anniversary date of grant. However, if a director dies, becomes disabled or retires at age 62 or later, then options vest at the rate of 25% for each full calendar year in which the director served. Options must be exercised while serving as a director or within three months following termination as director, unless termination results from death or disability, in which case options may be exercised during the one-year period following termination. In no event may options be exercised more than ten years after the date of grant.

Stock Incentive Plan

Our 2003 Stock Incentive Plan (the “Plan”) provides for the issuance of stock options and direct stock issuances covering up to 800,000 shares of our common stock. The maximum number of shares with respect to which options may be granted to any participant in any fiscal year of the company is 200,000 shares. In connection with a participant’s initial commencement of services with the company, a participant may be granted stock options for up to an additional 100,000 shares. The Plan administered by our board of directors or a committee appointed by the board of directors. Subject to the provisions of the Plan, the board or the committee will determine who will receive shares or options, the number of shares or options granted, the type of options granted (incentive or non-qualified), the manner of exercise and the exercise price of the options.

Bonus Incentive Plan

Officers (and other employees) participate in a Bonus Incentive Plan. Each officer is eligible to receive a discretionary bonus based upon individually established performance goals.

Deferred Compensation Plan

We have adopted a Deferred Compensation Plan to provide a select group of highly compensated management employees and directors with the opportunity to participate in a deferred compensation program. Under the Deferred Compensation Plan, participants may defer up to 100% of their base compensation and bonuses. We are required to make certain matching contributions in the form of the Company’s Common Stock, subject to vesting provisions. The Deferred Compensation Plan is not qualified under Section 401 of the Internal Revenue Code. The Company will pay participants upon retirement or termination of employment an amount equal to the amount of the deferred compensation plus investment returns and vested shares of the Company’s Common Stock.

This table is based upon information supplied by Schedules 13D and 13G, if any, filed with the SEC, and information obtained from our directors and named executive officers. Beneficial ownership is determined in accordance with the rules of the SEC and general includes voting and investment power with respect to securities.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Acquisition of BRC

In July 2003, we paid the final deferred payment to the BRC equity holders, which completed our $23.8 million acquisition of a 50% equity interest in BRC. Mr. Costamagna is the Chief Executive Officer of MTM s.r.l., an Italian corporation and a wholly owned subsidiary of BRC and, prior to the transaction, directly or indirectly held a 50% equity interest in BRC. In connection with this purchase, we paid $6,900,000 and issued 1,039,262 shares of common stock to Mr. Costamagna or his spouse, representing payment for one-half of the 50% equity interest he held directly or indirectly in BRC. Mr. Costamagna was elected to a three-year term as a director beginning June 12, 2003. Mr. Costamagna presently own 20% equity interest in BRC, and members of his immediate family own between 5% and 20% of the equity interest in BRC.

Loans to Executive Officers

In December 2000, we loaned Mr. Rasmussen, our Senior Vice President and Secretary, $100,000. The loan initially bore interest at a rate of 5% per annum and, since June 30, 2001, bears interest at a rate of 9% per annum. The loan became due and payable in full on July 31, 2002. As of January 9, 2004 approximately $3,000 was due and outstanding. We are negotiating with Mr. Rasmussen to recover the amounts due under the loan.

In September 2001, we loaned Mr. Rasmussen $175,000. The loan bore interest at a rate of 9% per annum. The loan became due and payable in full on July 31, 2002. The amount outstanding as of January 9, 2004 was approximately $216,000. We are negotiating with Mr. Rasmussen to recover the amounts due under the loan.

In December 2000, we loaned Mr. Hussain, former President of our spun off Quantum Subsidiary, $90,000. The loan bore interest at a rate of 5% per annum. This loan, plus accrued interest, was paid in full in July 2001.

In March 2001, we loaned three of our executive officers, Mr. Stemmler, Mr. Rasmussen and Mr. Hussain an aggregate of $3,913,854 ($1,565,547 each to Messrs. Stemmler and Hussain and $782,760 to Mr. Rasmussen) to finance the purchase of our common stock by exercise of options held by them. The loans were secured by (i) a pledge to us of a security interest in and lien upon shares of our common stock and stock options held by them and (ii) an agreement not to exercise any of our vested incentive stock options or to grant any third party any interest in such options. Additionally, Mr. Rasmussen pledged the equity value of his personal residence as collateral to secure his loan and Messrs. Stemmler and Rasmussen provided collateral to secure Mr. Hussain’s loan. Each loan bore interest at 9% per annum with a one year maturity. Each of these loans was repaid in full in July 2001.

We cannot make assurances that one or more of these related party loans are on terms no less favorable to the Company than might be obtained in arms’ length transactions. Because of the prohibitions arising under the Sarbanes-Oxley Act of 2002, the Company will not modify any outstanding loans nor will it enter into new related party transactions other than as permitted by applicable law at the time of the transaction.

Loan from Directors and Affiliates

On March 31, 2003, Mr. Simplot extended to us a loan commitment of $8.0 million expiring May 31, 2003, subsequently reduced to $1.5 million and extended to January 31, 2004. In connection with his initial commitment to provide the loan, we granted to Mr. Simplot warrants to purchase 200,000 shares of IMPCO stock at a price of $2.51, which expire in four years. We cancelled the loan commitment in July 2003.

In September 2003, we borrowed $500,000 from B.R.C., our subsidiary in which Mr. Costamagna owns a 20% interest. We repaid the note, with interest, in December 2003.

52

Purchase of Interest in a Subsidiary

On June 30, 2003 the 10% minority holder of IMPCO Mexicano exercised his put option for $0.5 million. The Company entered into an agreement whereby Mr. Simplot agreed to purchase the 10% interest for $0.5 million, and would allow the Company to re-purchase the 10% interest at cost. In December 2003, we paid Mr. Simplot $0.5 million, plus $49,998 interest, for his 10% interest and we now own 100% of IMPCO Mexicano.

Sale/Leaseback Transaction

In July 2002, we sold all the land and buildings, owned by BRC, our 50% owned subsidiary, to IMCOS2 S.r.l., a real estate investment company controlled by Mr. Costamagna, and to a leasing company, which then leased the land and buildings to IMCOS2 under capital lease arrangements. The portion of these land and buildings that were previously used by BRC were then leased back to BRC under operating lease arrangements. The terms of the rental agreement between BRC and IMCOS2 S.r.l. require that the Company does not terminate the rental agreement until eight years have expired.

SELLING STOCKHOLDERS

The following table sets forth the name of each of the selling stockholders, the number shares beneficially owned by each of the selling stockholders as of December 18, 2003, the number of shares that may be offered under this prospectus and the number and percentages of shares of our outstanding common stock owned by each of the selling stockholders after the offering is completed.

Because the selling stockholders may offer all, some or none of the shares of our common stock listed below, no estimate can be given as to the amount or percentage of our common stock that will be held by the selling stockholders upon termination of any of the sales. In addition, the selling stockholders identified below may have sold, transferred or otherwise disposed of all or a portion of their shares of common stock in transactions exempt from the registration requirements of the Securities Act since the date on which they provided to us the information regarding their shares of common stock.

None of the selling stockholders has held any position or office or had any other material relationship with us or any of our predecessors or affiliates within the past three years other than as a result of the ownership of our securities. We may amend or supplement this prospectus from time to time to update the disclosures contained herein.

Beneficial ownership is determined in accordance with the rules of the SEC and generally includes voting and investment power with respect to securities. To our knowledge, except as set forth in the footnotes to this table, each person named in this table has sole voting and investment power with respect to the shares shown as beneficially owned by such person.

As of January 9, 2004, 17,090,692 shares of our common stock and no shares of preferred stock were outstanding. In computing the number of shares beneficially owned by a person and the percentage of ownership of that person, shares of common stock issuable upon the exercise of options and warrants that are currently exercisable or exercisable within 60 days of January 9, 2004, are deemed to be outstanding and beneficially owned by the person holding the options and warrants, as the case may be, but are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

PLAN OF DISTRIBUTION

On December 19, 2003, we issued and sold to the selling stockholders a total of 1,500,000 shares of common stock at a price per share of $6.40. The issuance and sale of such shares were exempt from registration under the Securities Act owing to the exemptions afforded by Section 4(2) and Rule 506 of Regulation D thereunder. The selling stockholders may sell the common stock offered by this prospectus to one or more underwriters or dealers for public offering, through agents, directly to purchasers or through a combination of any such methods of sale. The name of the underwriter, dealer or agent involved in the offer and sale of the common stock, the amounts underwritten and the nature of its obligation to take the common stock will be provided in the applicable prospectus supplement.

We will pay all expenses incurred in connection with the registration of the shares covered by this prospectus. Brokerage commissions, underwriters’ fees, discounts and commissions and similar selling expenses, if any, attributable to the sale of the shares covered by this prospectus will be borne by the selling stockholders.

When used in this prospectus, the term “selling stockholders” includes donees, pledgees, transferees or other successors-in-interest selling shares received after the date of this prospectus from the selling stockholders as a gift, pledge, partnership distribution or other non-sale related transfer. The selling stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. The shares covered by this prospectus may be offered and sold from time to time by the selling stockholders on The Nasdaq National Market or otherwise at prices and on terms then prevailing or at prices related to the then-current market price and by one or more of, or a combination of, the following methods:

• purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

• ordinary brokerage transactions and transactions in which the broker solicits purchasers;

• block trades in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

• an over-the-counter distribution in accordance with the rules of the Nasdaq National Market;

• in privately negotiated transactions; and

• in options transactions.

In addition, any shares that qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than pursuant to this prospectus.

In connection with distributions of the shares or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of the common stock in the course of hedging the positions they assume with the selling stockholders. The selling stockholders may also sell the common stock short and redeliver the shares to close out such short positions. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). The selling stockholders may also pledge shares to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution may effect sales of the pledged shares pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of its securities, nor is there an underwriter or coordinating broker acting in connection with the proposed sale of the shares by the selling

57

stockholders. Upon notification to us by the selling stockholders that any arrangements have been entered into with a broker or dealer for the sale of shares through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing:

• the name of the participating brokers or dealers;

• the number of shares involved;

• the price at which such shares were sold;

• the commissions paid or discounts or concessions allowed to such brokers or dealers, where applicable;

• that such brokers or dealers did not conduct any investigation to verify the information set forth or incorporated by reference in this prospectus; and

• other facts material to the transaction.

In effecting sales, broker-dealers or agents engaged by the selling stockholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the selling stockholders in amounts to be negotiated immediately prior to the sale.

In offering the shares covered by this prospectus, the selling stockholders and any broker-dealers who execute sales for the selling stockholders may be deemed to be “underwriters” within the meaning of the Section 2(11) of the Securities Act in connection with such sales. Any profits realized by the selling stockholders and the compensation of any broker-dealer may be deemed to be underwriting discounts and commissions. Since the selling stockholders and any broker-dealers who execute sales for the selling stockholders may be deemed “underwriters,” they will be subject to the prospectus delivery requirements of the Securities Act. We will make copies of this prospectus available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act.

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and its affiliates.

We have agreed to indemnify the selling stockholders against specific liabilities, including liabilities arising under the Securities Act. The selling stockholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares covered by this prospectus against specific liabilities, including liabilities arising under the Securities Act.

We have also agreed to use our reasonable best efforts to prepare and file amendments and supplements to the registration statement to the extent necessary to keep the registration statement effective until the first to occur of the date on which all shares offered hereby have been disposed of in compliance with the prospectus delivery requirements under the Securities Act, or such time as an opinion of counsel to the Company has been rendered to the effect that disposition of the common stock offered hereby may be effected without registration in compliance with the Securities Act. There is no assurance that the selling stockholders will offer for sale or sell any of the shares of common stock offered by this prospectus.

DESCRIPTION OF OUR CAPITAL STOCK

Our authorized capital stock consists of 100,000,000 shares of common stock having a par value of $0.001 per share and 500,000 shares of preferred stock having a par value of $0.001 per share. As of March 18, 2004, there were outstanding 18,591,021 shares held by 517 shareholders of record and no shares of preferred stock.

Common stock

Subject to the rights specifically granted to holders of any then outstanding shares of our preferred stock, our common stockholders are entitled to vote together as a class on all matters submitted to a vote of our stockholders and are entitled to any dividends that may be declared by our board of directors. Our common stockholders do not have cumulative voting rights. Upon our dissolution, liquidation or winding up, holders of our common stock are entitled to share ratably in our net assets after payment or provision for all liabilities and any preferential liquidation rights of our preferred stock then outstanding. Our common stockholders have no preemptive rights to purchase shares of our stock. The issued and outstanding shares of our common stock are not subject to any redemption provisions and are not convertible into any other shares of our capital stock. All outstanding shares of our common stock are, and the shares of common stock to be issued in this offering will be, upon payment therefore, fully paid and non-assessable. The rights, preferences and privileges of holders of our common stock will be subject to those of the holders of any shares of our common stock and preferred stock we may issue in the future.

Preferred Stock

Our articles of incorporation provide for the issuance of up to 500,000 shares of preferred stock. As of the date of this prospectus, there are no outstanding shares of preferred stock, and we do not have any current plans to issue any shares of preferred stock.

Issuance of Additional Common Stock and Preferred Stock

Subject to certain limitations prescribed by law, our board of directors is authorized, without further stockholder approval, from time-to-time to issue up to 100,000,000 shares of our common stock and 500,000 of our preferred stock, in one or more series. Each new series of common stock or preferred stock may have different rights and preferences that may be established by our board of directors. A majority of our directors must approve any issuance by us of our common stock or preferred stock. The rights and preferences of future series of common stock or preferred stock may include:

• number of shares to be issued

• dividend rights and dividend rates

• right to convert the preferred stock into a different type of security

• voting rights attributable to the preferred stock

• right to receive preferential payments upon a liquidation of the company

• right to set aside a certain amount of assets for payments relating to the preferred stock

In addition, as of March 18, 2004, we have outstanding options to purchase 2,748,533 shares of our common stock of which 766,004 are vested and presently exercisable.

We have reserved 800,000 shares of our common stock for issuance under our 2003 stock incentive plan.

Anti-Takeover Considerations and Special Provisions of Our Certificate of Incorporation and Our Bylaws

Certificate of incorporation and bylaws.    A number of provisions of our certificate of incorporation and bylaws concern matters of corporate governance and the rights of our stockholders. Provisions that grant our board of directors the ability to issue shares of common and preferred stock and to set the voting rights, preferences and other terms thereof may discourage takeover attempts that are not first approved by our board of directors, including takeovers which may be considered by some stockholders to be in their best interests. Certain provisions could delay or impede the removal of incumbent directors or the assumption of control by stockholders, even if such removal or assumption would be beneficial to our stockholders. These provisions also could discourage or make more difficult a merger, tender offer or proxy contest, even if they could be favorable to the interests of stockholders, and could potentially depress the market price of our common stock. Our board of directors believes that these provisions are appropriate to protect our interests and the interests of our stockholders.

Classified board of directors.    Our bylaws divide our board of directors into three classes. Moreover, no director may be removed prior to the expiration of his or her term except for cause. These provisions in our bylaws may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of our company and may maintain the incumbency of our board of directors, because this structure generally increases the difficulty of, or may delay, replacing a majority of the directors.

Meetings of stockholders.    Our bylaws provide that annual meetings of our stockholders may take place at the time and place established by our board of directors. A special meeting of our stockholders may be called at any time by our secretary or any other officer, whenever directed by the Board of Directors or by the Chief Executive Officer.

Filling of board vacancies.    Vacancies and newly created directorships resulting from any increase in the authorized number of directors may be filled by the affirmative vote of a majority of our directors then in office.

Amendment of the bylaws.    Our bylaws may be amended or repealed by a majority of our board of directors. Any amendment or repeal of our bylaws which has not previously received the approval of our board shall require for adoption the affirmative vote of the holders of at least a majority of the voting power of our then outstanding shares of capital stock entitled to vote at any duly convened annual or special meeting of the stockholders, in addition to any other approval which is required by law, the certificate of incorporation, bylaws or otherwise.

Stockholder Protection Rights Agreement.    On June 30, 1999, our board of directors adopted a Stockholder Protection Rights Agreement and declared a dividend of one right on each outstanding share of our common stock. Each right entitles the holder, upon certain events, to purchase, at an exercise price of $45 per right, shares of common stock with a value equal to twice the exercise price. The dividend was paid on July 26, 1999 to stockholders of record on July 12, 1999.

Transfer Agent and Registrar

Mellon Bank is the transfer agent and registrar for our common stock.

Listing

Our common stock is traded on The Nasdaq National Market under the symbol “IMCO”.

SHARES ELIGIBLE FOR FUTURE SALE

Sales of substantial amounts of our common stock in the public market, or the perception that such sales may occur, could adversely affect the prevailing market price and impair our ability to raise capital in the future.

As of March 18, 2004, 18,625,612 and 18,591,021 shares of our common stock were issued and outstanding, respectively, 16,928,203 of which are freely tradable without restriction or further registration under the Securities Act after giving effect to this prospectus or may be eligible for immediate sale pursuant to Rule 144 under the Securities Act. The remaining 1,662,818 shares, which are otherwise freely tradable, are subject to a lockup agreement that restricts their resale until certain dates beginning August 2004. The following table presents the relevant expiration dates and the number of shares as to which lockup expires:

Date	Number of Shares Available for Sale
August 1, 2004	277,691
February 1, 2005	460,601
August 1, 2005	460,601
February 1, 2006	463,925

Other shares, which are not outstanding, may be issued and become available for resale. As of the date of this prospectus, an aggregate of 795,000 shares are issuable upon exercise of outstanding warrants. In addition, we have granted as of March 18, 2004, options to purchase an aggregate of 2,748,533 shares of common stock under our stock option plans. All of the shares underlying these options have previously been registered and, subject to the applicable vesting requirements, upon exercise of these options the underlying shares may be resold into the public market.

In general, under Rule 144 as currently in effect, a person who has beneficially owned restricted securities for at least one year would be entitled to sell within any three-month period a number of shares that does not exceed the greater of the following:

• one percent of the number of shares of common stock then outstanding, or

• the average weekly trading volume of the common stock during the four calendar weeks preceding the sale.

Sales under Rule 144 are also subject to requirements with respect to manner-of-sale requirements, notice requirements and the availability of current public information about us. Under Rule 144(k), a person who is not deemed to have been our affiliate at any time during the three months preceding a sale, and who has beneficially owned the shares proposed to be sold for at least two years, is entitled to sell his or her shares without complying with the manner-of-sale, public information, volume limitation, or notice provisions of Rule 144.

Rule 701, as currently in effect, permits our employees, officers, directors, and consultants who purchased shares pursuant to a written compensatory plan or contract to resell these shares in reliance upon Rule 144, but without compliance with the specific restrictions of Rule 144. Rule 701 provides that affiliates may sell their Rule 701 shares under Rule 144 without complying with the holding period requirement and that non-affiliates may sell their shares in reliance on Rule 144 without complying with the holding period, public information, volume limitation, or notice provisions of Rule 144.

REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Stockholders

IMPCO Technologies, Inc.

We have audited the accompanying consolidated balance sheets of IMPCO Technologies, Inc. and subsidiaries as of April 30, 2002, December 31, 2002 and 2003 and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the two years in the period ended April 30, 2002, the eight months ended December 31, 2002 and the year ended December 31, 2003. Our audits also included the financial statement schedule listed in the Index to the financial statements on page F-1. These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. 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 provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of IMPCO Technologies, Inc. and subsidiaries at April 30, 2002, December 31, 2002 and 2003 and the consolidated results of their operations and their cash flows for each of the two years in the period ended April 30, 2002, the eight months ended December 31, 2002 and the year ended December 31, 2003 in conformity with accounting principles generally accepted in the United States. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth herein.

As more fully described in Note 16 to the consolidated financial statements, the Company changed its method of accounting for goodwill and other intangible assets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Summary of Significant Accounting Policies

(a) Basis of presentation and description of the business—The consolidated financial statements of IMPCO Technologies, Inc. (“IMPCO” or the “Company”) include the accounts of the Company and its majority owned subsidiaries IMPCO-BERU Technologies B.V. (“IMPCO BV”); its wholly owned subsidiaries IMPCO Technologies, Pty. Limited (“IMPCO Pty”), IMPCO Tech Japan K.K. (“IMPCO Japan”) and Grupo I.M.P.C.O. Mexicano, S. de R.L. de C.V. (“IMPCO Mexicano); and its joint ventures Minda IMPCO Technologies Limited, IMPCO-Egypt, and CNGC-IMPCO Technologies, LLC (“CNGC”). The Company has a 40% interest in a joint venture, Minda IMPCO Limited, and uses the equity method for reporting the results of this entity. The Company has purchased 50% of B.R.C. Societá a Responsabilitá Limitata (“BRC”). The Company uses the equity method to recognize the assets and liabilities of BRC in the Company’s consolidated results. All significant intercompany accounts and transactions have been eliminated in consolidation.

The Company is a designer, manufacturer and supplier of components and systems that store gaseous fuels and monitor and control the pressure and flow of those fuels for use in primarily internal combustion engines.

On July 23, 2002, the Company completed the distribution and spin-off of Quantum Technologies Worldwide, Inc. (“Quantum”), a wholly owned subsidiary, by distributing one share of Quantum common stock for every share of IMPCO common stock held on the record date, July 5, 2002. The Company released Quantum from its liability related to the $8.6 million line of credit with Bank of America and contributed cash of $15.0 million to supply liquidity and Quantum’s short-term operating needs. As a result of the spin-off, the Company no longer holds any continuing interest in Quantum and has reported Quantum as a discontinued operation in the consolidated financial statements for all periods presented.

On November 14, 2002, the Company changed its fiscal calendar from April 30 to December 31. The consolidated financial statements and the accompanying notes include the “transition period” for the eight months ended December 31, 2002.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. This basis of accounting contemplates the recovery of the Company’s assets and the satisfaction of its liabilities in the normal course of conducting business. The Company uses cash generated from operations, bank financings and sales of its equity securities to fund capital expenditures and research and development, as well as to invest in and operate existing operations and new businesses. In July 2003, the Company concluded new loan agreements with Bison Capital Structured Equity Partners, LLC (“Bison”) for $20.0 million and with LaSalle Business Credit, LLC (“LaSalle”) for a maximum amount of $12.0 million. From these proceeds, the Company repaid the Bank of America line of credit and term loans for a total of $11.3 million. In December 2003, the Company completed a private placement to institutional investors of 1.5 million shares of its common stock in which it received approximately $9.0 million in net proceeds, after discounts, commissions and expenses.

At December 31, 2003 the Company was not in compliance under terms of the LaSalle and Bison agreements. See also Note 3. At December 31, 2003 the Company had received waivers from LaSalle and Bison for covenant non-compliance conditions. Bison granted the Company a modified EBITDA calculation for 2004 and a further waiver in maintaining its Term Loan status as a long term liability throughout 2004. LaSalle granted the Company an amendment on March 12, 2004 which resulted in additional borrowing line capacity of $2.6 million. Management believes that LaSalle will work with the Company to amend its credit arrangement for the remainder of its term. Accordingly, management believes that the Company has sufficient resources to meet its current financial obligations and finance its operations through December 31, 2004.

It is possible that the Company may require additional sources of financing in order to capitalize on opportunities that management believes currently exists in the alternative fuel market and to invest in long-term

business opportunities. These additional sources of financing may include bank borrowings or public or private offerings of equity or debt securities. No assurance can be given that such additional sources of financing will be available on acceptable terms, if at all.

(b) Cash and Cash Equivalents—The Company considers all highly liquid investments with maturity of three months or less when purchased to be cash equivalents.

(c) Restricted Cash—The Company classifies cash and cash equivalents that are restricted from operating use for the next twelve months as restricted cash. Amounts restricted for longer than twelve months are classified as other assets. When the restrictions are no longer in-place, the amounts are reclassified to cash and cash equivalents.

(d) Inventories—Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out (FIFO) method while market is determined by replacement cost for raw materials and parts and net realizable value for work-in-process and finished goods.

(e) Equipment and leasehold improvements—Equipment and leasehold improvements are stated on the basis of historical cost. Depreciation of equipment is provided using the straight-line method over the assets’ estimated useful lives, ranging from three to seven years. Amortization of leasehold improvements and equipment under capital leases is provided using the straight-line method over the shorter of the assets’ estimated useful lives or the lease terms.

(f) Intangibles arising from acquisitions—Intangibles arising from acquisitions, primarily goodwill, are recorded based on the excess of the acquisition cost over the fair value of amounts assigned to tangible assets and liabilities. Goodwill and other unidentifiable intangible assets that arise from acquisitions are subject to an annual evaluation in accordance with SFAS No. 142, Goodwill and Other Intangible Assets, for the purpose of determining any impairment and would be recognized as goodwill expense.

In June 2001, the Financial Accounting Standards Board issued Statements of Financial Accounting Standards No. 141, Business Combinations, and SFAS No. 142, Goodwill and Other Intangible Assets, effective for fiscal years beginning after December 15, 2001. Under these rules, goodwill is no longer amortized but is subject to annual impairment tests in accordance with the Statement. Other identifiable intangible assets continue to be amortized over their useful lives.

The Company has applied the rules on accounting for goodwill and other intangible assets beginning in the first quarter of the transition period ended December 31, 2002. Application of the nonamortization provisions of the Statement has resulted in an increase in net income of approximately $0.5 million ($0.03 per share) for the transition period ended December 31, 2002 and approximately $0.8 million ($0.05 per share) for the fiscal year ended December 31, 2003. The Company has completed the impairment tests as required upon adoption of SFAS No. 142 and the annual evaluation thereof for impairment and has determined that there is no impairment to its recorded goodwill balance as of December 31, 2003.

(g) Warranty costs—Estimated future warranty obligations related to certain products are provided by charges to operations in the period in which the related revenue is recognized. Estimates are based, in part, on historical experience.

(h) Research and development costs—Research and development costs are charged to expense as incurred. Equipment used in research and development with alternative future uses is capitalized.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(i) Revenue recognition—Revenue is recognized when title is transferred, ordinarily when products are shipped, and when management is reasonably assured of collectibility. Also, in accordance with Emerging Issues Task Force No. 00-10, the Company includes the costs of shipping and handling, when incurred, in cost of goods sold.

(j) Minority interests in subsidiaries—The balance sheet amounts in minority interest at December 31, 2003 represent 49% of the equity held by the single minority stockholder in IMPCO BV, 49% of the equity held by a single minority stockholder in IMPCO Fuel Systems, and a subsidiary of IMPCO Pty, 40% of the equity held by a joint venture partner in Minda IMPCO. Minority interest represents the minority stockholder’s proportionate share of equity in those subsidiaries.

(k) Net income per share—Basic income per share is computed by dividing net income applicable to common stock by the weighted average shares of common stock outstanding during the period. Diluted earnings per share is computed based on the weighted average number of shares of common stock outstanding, and if dilutive, all common stock equivalents. In addition to net income (loss) per share, basic and diluted earnings per share are also presented for income (loss) from continuing operations and income (loss) from discontinued operation as appropriate.

(l) Stock based compensation—In October 1995, the Financial Accounting Standards Board issued SFAS No. 123 Accounting For Stock Based Compensation, which established accounting and reporting standards for stock based employee compensation plans effective after fiscal year 1996. SFAS No. 123 encourages entities to adopt the fair value based method of accounting; however, it also allows an entity to continue to measure compensation cost using the intrinsic value based method prescribed by Accounting Principles Board No. 25. Entities electing to remain on the “intrinsic value based” method must make certain pro forma disclosures as if the new fair value method had been applied. At this time, the Company has not adopted the recognition provision of SFAS No. 123, but has provided pro forma disclosures.

In December 2002, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 148, Accounting For Stock Based Compensation—Transition and Disclosure. SFAS No. 148 amended SFAS No. 123 to provide new guidance concerning the transition when a company changes from the intrinsic-value method to the fair-value method of accounting for employee stock-based compensation cost. As amended by SFAS No. 148, SFAS No. 123 also requires additional disclosure regarding such cost in annual financial statements and in condensed interim financial statements. Certain disclosure provisions of SFAS No. 148 were adopted by the Company in its financial statements prepared as of December 31, 2003.

SFAS No. 123, as amended by SFAS No. 148, requires pro forma information regarding net income and net income per share to be disclosed for new options granted after fiscal year 1996. The fair value of these options was determined at the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

	Fiscal Years Ended April 30,				Eight Months Ended December 31, 2002		Fiscal Year Ended December 31, 2003
	2001		2002
Expected dividend yield	0.0	%	0.0	%	0.0	%	0.0	%
Expected volatility	69.5	%	74.8	%	79.3	%	83.3	%
Risk free interest rate	5.6	%	5.0	%	4.4	%	4.0	%
Expected life of the option (years)	6.0		6.0		6.0		6.0

F-10

IMPCO TECHNOLOGIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The estimated fair value of the options is amortized to expense over the options’ vesting period for pro forma disclosures. The per share “pro forma” for the effects of SFAS No. 123, as amended by SFAS 148, is not indicative of the effects on reported net income/loss for future years. The Company’s “reported” and “pro forma” information for the periods April 30, 2001 and 2002, and at December 31, 2002 and 2003 are as follows (in thousands of dollars except per share data):

	Fiscal Years Ended April 30,						Eight Months Ended December 31, 2002			Fiscal Year Ended December 31, 2003
	2001			2002
Loss as reported	$	(13,103	)	$	(27,236	)	$	(28,394	)	$	(6,900	)

Proforma net loss	$	(13,564	)	$	(27,927	)	$	(28,939	)	$	(8,912	)
Basic loss per share:
Net loss as reported	$	(1.32	)	$	(2.45	)	$	(1.98	)	$	(0.41	)
Proforma loss	$	(1.37	)	$	(2.52	)	$	(2.01	)	$	(0.54	)
Diluted loss per share:
Net loss as reported	$	(1.19	)	$	(2.45	)	$	(1.98	)	$	(0.41	)
Proforma loss	$	(1.23	)	$	(2.52	)	$	(2.01	)	$	(0.54	)

The Financial Accounting Standards Board has also issued Interpretation No. 44, “Accounting for Certain Transactions Involving Stock Compensation.” The Interpretation addresses implementation practice issues in accounting for compensation costs under existing rules prescribed by Accounting Principles Board No. 25. The rules are applied prospectively to all new awards, modifications to outstanding awards and changes in grantee status after July 1, 2000, with certain exceptions. The Company considers the impact of these rules when adopting new stock option plans and when granting any options.

(m) Impairment of long-lived assets and long-lived assets to be disposed of—Impairment losses are recorded on long-lived assets used in operations when an indicator of impairment (significant decrease in market value of an asset, significant change in extent or manner in which the asset is used or significant physical change to the asset) is present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. The Company has not experienced any significant changes in the business climate or in the use of assets that would require the Company to write down the value of the assets recorded in the balance sheet.

In August 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (SFAS No. 144), which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and supersedes SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of”, and the accounting and reporting provisions of APB Opinion No. 30, “Reporting the Results of Operations For a Disposal of a Segment of a Business”. SFAS No. 144 is effective for fiscal years beginning after December 15, 2001, with earlier application encouraged. We adopted SFAS No. 144 as of May 1, 2002, which did not have a significant impact on the Company’s financial position and results of operations, except that the Quantum operations is presented as a discontinued operation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(n) Use of estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of 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.

(o) Reclassifications—Certain prior year amounts have been reclassified to conform to current presentations.

(p) Foreign currency translation—Assets and liabilities of the Company’s foreign subsidiaries are generally translated at current exchange rates, and related revenues and expenses are translated at average exchange rates in effect during the period. Resulting translation adjustments are recorded as a foreign currency component of other comprehensive income in stockholders’ equity. The results and financial condition of the Company’s international operations are affected by changes in exchange rates between certain foreign currencies and the U.S. Dollar. The functional currency for all of the Company’s international subsidiaries is the local currency of the subsidiary. An increase in the value of the U.S. Dollar increases costs incurred by the subsidiaries because most of its international subsidiaries’ inventory purchases are U.S. Dollar denominated. The Company seeks to manage its foreign currency economic risk by minimizing its U.S. Dollar investment in foreign operations using foreign currency term loans and lines of credit to finance the operations of its foreign subsidiaries. At December 31, 2003, the Company had a single foreign exchange forward contract in which gains and losses are ordinarily recognized in the consolidated statement of operations as the fair value of the contracts fluctuates.

Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency, except those transactions that operate as a hedge of an identifiable foreign currency commitment, are included in the results of operations as incurred.

(q) Financial instruments—At December 31, 2003, the Company’s financial instruments recorded on the balance sheet include cash equivalents, capital lease obligations, short-term bank debt, and restricted cash. Because of the short maturity, short-term bank debt approximates fair value. At December 31, 2003, the fair value of the Company’s long-term debt and capital lease obligations approximated carrying value.

The Company periodically enters into foreign currency forward contracts and interest rate swap agreements. When the Company enters into foreign currency forward contracts, it does so to hedge identifiable foreign currency commitments. Foreign currency contracts reduce the Company’s exposure to unfavorable fluctuations in foreign currencies versus the U.S. dollar. Realized gains and losses on these contracts are included in the measurement of the related foreign currency transaction. The Company, from time to time, uses interest rate swap agreements to manage interest rate risk on its floating rate debt portfolio. Each interest rate swap is matched as a hedge against a specific debt instrument and has the same notional amount and tenor as the related debt instrument principle. As of December 31, 2003, the Company had a single foreign exchange forward contract of approximately $0.5 million for the purpose of hedging foreign exchange exposure.

[r] New accounting pronouncements—In January 2003, the Financial Accounting Standards Board (“FASB”) issued Interpretation No. 46, Consolidation of Variable Interest Entities, an Interpretation of Accounting Research Bulletin No. 51, (“FIN 46”). FIN 46 introduces a new consolidation model, the variable interests model, which determines control (and consolidation) based on potential variability in gains and losses of the entity being evaluated for consolidation. The requirements for FIN 46, including its disclosures, apply immediately.

FIN 46 provides guidance for determining whether an entity qualifies as a variable interest entity (“VIE”) by considering, among other considerations, whether the entity lacks sufficient equity or its equity holders lack

adequate decision-making ability. If the entity does not qualify as a VIE, then the consolidation criteria is based on previously established accounting standards. Qualifying VIEs are covered by FIN 46 and are individually evaluated for consolidation based on their variable interests. FIN 46 requires consideration and estimates of a significant number of possible future outcomes of the VIE as well as the probability of each outcome occurring. Based on the allocation of possible outcomes, a calculation is performed to determine which party, if any, has a majority of potential negative outcomes (expected losses) or a majority of the potential positive outcomes (expected residual returns), with an emphasis on negative outcomes. That party, if any, is the primary beneficiary and is required to consolidate the VIE. The effective date for FIN 46 was deferred for public companies until the end of periods ending on or after December 15, 2003. Adoption of FIN 46 did not have an impact on the Company.

Deferred tax assets non-current	$	10,601		$	29,129		$	8,405		$	9,476

The increase in valuation allowance of approximately $2.5 million is attributable to the increase in deferred tax assets, primarily due to the increase of net operating loss carryforwards. The total valuation allowance of approximately $26.5 million as of December 31, 2003 was recognized based on the weight of available evidence that it is more likely than not that this portion of the deferred tax asset will not be realized within the next three years, notwithstanding that some of those assets may have longer lives under applicable tax laws. Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company believes, based on its history of prior operating earnings, its spin-off of the Quantum division and its expectations of future earnings, that operating income of the Company will more likely than not be sufficient to realize the future benefits of the amount classified as net deferred tax asset. Future adverse changes in market conditions, poor operating results or a decline in our projections about future profitability may affect the Company assessment of the adequacy of the valuation allowance and, consequently, the net carrying value of net deferred tax assets. In the event that the Company determines that it is more likely than not that it would be unable to realize an additional portion of the net deferred tax asset, an additional adjustment to the deferred tax asset valuation allowance would be charged to income in the period such determination was made.

For the year ended December 31, 2003, the Company has a federal research and development tax credit carryforward available for federal income tax purposes of approximately $5.1 million that, if not used, will begin to expire in 2009. Federal net operating loss carryforwards of $72.0 million will begin to expire in 2021. Additionally, the Company has an alternative minimum tax credit carryforward available for federal income tax purposes of approximately $0.2 million that will carryforward indefinitely until utilized and a foreign tax credit of $0.7 million that expires in 2004 if not utilized. The Company also has research and development credit carryforwards for state income tax purposes of approximately $4.6 million, which do not expire for tax reporting purposes. State net operating loss carryforwards of approximately $33.0 million which will begin to expire in 2008.

(d) Pension Expense

The Company’s 51% owned subsidiary in The Netherlands has a defined benefit pension plan for employees over 25 years of age and mandatory retirement at age 65. The post-retirement benefit is 70% of the highest annual compensation level earned during employment. The Company purchases and fully funds this benefit with a state-approved insurance carrier who takes full responsibility for paying post-retirement benefits. For the years ended April 30, 2001 and 2002, the eight months ended December 31, 2002, and the year ended December 31, 2003, the Company paid approximately $0.1 million, $0.3 million, $0.2 million, and $0.5 million, respectively.

8.    Stockholders’ Equity

(a) Stockholder Protection Rights Agreement

On June 30, 1999, the Company’s Board of Director’s adopted a Stockholder Protection Rights Agreement and declared a dividend of one right on each outstanding share of IMPCO common stock. Each right entitles the holder, upon certain events, to purchase, at an exercise price of $45 per share, shares of common stock with a value equal to twice the exercise price. The dividend was paid on July 26, 1999 to stockholders of record on July 12, 1999.

(b) Stock options

The Company has eight stock option plans that provide for the issuance of options to key employees and directors of the Company at the fair market value at the time of grant. Options under the plans generally vest in four or five years and are generally exercisable while the individual is an employee or a director, or ordinarily within one month following termination of employment. In no event may options be exercised more than ten years after date of grant. On June 12, 2003, the stockholders of IMPCO approved the 2003 Stock Incentive Plan (“Plan”), which provides for the issuance of up to 800,000 shares of the Company’s common stock. Subject to the provisions of the Plan, the Company’s board of directors or a committee appointed by the board will determine who will receive shares or options, the number of shares or options granted, the type of options granted (incentive or non-qualified), the manner of exercise and the exercise price of the options.

In connection with the spin-off of Quantum, all stock options outstanding on the spin-off date were split into one option of IMPCO and one option of Quantum stock. The exercise price of both the IMPCO and Quantum stock options was adjusted based on the relative market values of both companies on the first trading day following the spin-off. Options exercised prior to the spin-off of Quantum were made at the exercise price prior to such adjustment. All vesting schedules remain the same and the option holders are not required to exercise their options concurrently.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

employee stock options. No compensation expense is recorded under APB 25 because the exercise price of the Company’s employee common stock options equals the market price of the underlying common stock on the grant date.

(c) Warrants

On January 11, 2002, the Company completed a private placement of 2,000,000 shares of common stock at a price of $11.25 per share for $22.5 million. The Company also issued to the investors warrants to purchase an aggregate of 200,000 shares of common stock at an exercise price of $13.25 per share. Each purchaser was issued a warrant to purchase one-tenth of a share of common stock for each share of common stock purchased under the agreement. In addition, the Company issued warrants to purchase an aggregate of 100,000 shares of common stock to the placement agent in connection with the transaction. The total of 300,000 warrants were outstanding at December 31, 2002 and the warrants are exercisable at any time until January 11, 2006.

In connection with a $8.0 million loan commitment obtained in March 2003 from a Company director that expired on July 31, 2003, the Company granted 200,000 warrants, vesting immediately, to the director to purchase IMPCO stock at a price of $2.51. The warrants expire in four years. During 2003, the Company utilized the Black-Scholes model to determine the fair value of the options and recognized as expense approximately $0.3 million.

During April and May of 2003, the Company entered into agreements with investors to provide approximately $3.1 million in bridge loans, of which $1.4 million was from an entity related to one of the Company’s directors. In conjunction with the bridge loan agreements the Company issued warrants to the investors to purchase 305,000 shares of the Company’s common stock at $2.46, or 120% of market price. As of December 31, 2003, 10,000 warrants had been exercised and the bridge loans were repaid. See Note 3(g). During 2003, the Company utilized the Black-Scholes option pricing model and determined the fair value of the 305,000 warrants to be approximately $0.4 million. This amount was recognized on the statement of operations as part of interest expense.

On July 21, 2003, the Company issued 500,000 warrants, fully vested, to Bison to acquire the Company’s stock in connection with the issuance of a $20.0 million senior secured subordinated promissory note at a price of $2.00. In September 2003, Bison exercised all of the warrants and the Company received $1.0 million in proceeds from the exercise of the warrants. During 2003, the Company determined the fair value of the 500,000 Bison warrants to be approximately $2.6 million. The assumptions used in the Black-Scholes option pricing model were (i) expected term of the options – 4 years, (ii) annual volatility – 91.3%, (iii) risk-free interest rate –2.6%, market price of the IMPCO common stock on the date of issuance – $6.02, and (iv) dividends paid – none. During 2003, approximately $0.3 million was recognized as interest expense and the deferred portion of approximately $2.3 million is classified as part of additional paid in capital on the December 31, 2003 balance sheet and is amortized to interest expense ratably over the four year term of the loan.

(d) Notes receivable from officers

On March 2, 2001, the Board of Directors authorized loans to three officers of the Company for the exercise of options to purchase Company stock from former stockholders. The loans accrued interest at 9% and were fully collateralized by a security interest in and lien upon shares of common stock of the Company and certain vested Company nonqualified stock options issued to the officers. Additionally, the loans were secured by the personal residence of one of the officers and were cross-collateralized. Each of these loans was repaid in full in July 2001.

Based on the nature of these customers, credit is generally granted without collateral being required. The Company does not anticipate that a significant credit risk exists as a result of these customer relationships.

During the fiscal year ended December 31, 2003, the Company had one customer with net revenues greater than ten percent of consolidated net revenues.

11.    Business Segment and Geographic Information

Business Segments.    The Company currently has two reporting segments organized along geographical boundaries: a domestic segment consisting of U.S. Operations and the rest of the world known as the International segment. Prior to 2001, the U.S. Operations segment was called the Gaseous Fuel Products Division. The domestic segment sells products including parts and conversion systems to OEMs and the aftermarket. The Company’s International Operations in Australia, Europe, Japan, India, and Mexico provide distribution for the Company’s products, predominantly from its domestic division and some product assembly.

Corporate expenses consist of general and administrative expenses at the corporate level and include the amortization of identifiable intangibles. Intersegment eliminations are primarily the result of intercompany sales from our domestic division to our International Operations.

The Company evaluates performance based on profit or loss from operations before interest and income taxes. The accounting policies of the reportable segments are the same as those described in the Summary of Significant Accounting Policies.

In accordance with SFAS No. 142, Goodwill and Other Intangible Assets, amortization of goodwill is no longer permitted. No such amortization expense for goodwill was recognized for the eight-month period ended December 31, 2002 or the fiscal year ended December 31, 2003. The following data shows the effect on net loss and net loss per share of common stock if the provisions of SFAS No. 142 had been in effect for the fiscal years ended April 30, 2001, and 2002 (in thousands of dollars except for per share data).

Accordingly, quarterly amounts may not add to the annual amounts because of differences in the average common shares outstanding during each period and, with regard to diluted per common share amounts only, because of the effect of potentially dilutive securities only in the periods in which the effect would have been dilutive.

The Company made certain adjustments in the 4th quarter of fiscal year 2003. These adjustments were to: 1) Increase inventory obsolescence reserves by $0.3 million; 2) Increase the allowance for doubtful accounts by $0.2 million; 3) Write-off of bad debt expense by $0.4 million; and 4) Increase in the valuation allowance for deferred income taxes by $2.5 million.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For the years ended December 31, 2001, 2002 and 2003

(In thousands of Euros)

1.    Basis of Presentation and Description of Business

The consolidated financial statements of BRC S.r.l. (“BRC” or the “Company”) include the accounts of the Company, of its wholly owned subsidiary MTM S.r.l. and of MTM’s wholly owned subsidiary BRC Argentina S.A. and majority owned subsidiaries BRC Brasil S.A. and NG LOG Armazens Gerais Ltda. All significant intercompany accounts and transactions have been eliminated. The Company has a 50% interest in the joint ventures WMTM and MTE and an 18.5% interest in Jehin and uses the equity method for reporting the results of these entities.

Prior to February 2001, MTM was owned directly by Mariano and Piero Costamagna. In February 2001, Mariano and Piero Costamagna incorporated BRC S.r.l. and contributed their shareholdings in MTM to BRC S.r.l. This contribution has been accounted for as a reorganization under common control under which it is assumed that BRC S.r.l. has been the parent company from January 1, 2001 for all periods presented. Consequently, the carrying amounts of MTM and its subsidiaries were not adjusted at their transfer dates in accounting for the reorganization and the Company’s quota capital has been reported in the consolidated financial statements as if outstanding since January 1, 2001.

On July 22, 2003, the shareholders of BRC completed the sale of 50% of the Company to IMPCO Technologies Inc., a U.S. Company.

The Company is a designer, manufacturer and supplier of fuel technology systems for automobiles that enable traditional internal combustion engines to run on alternative fuels such as propane and natural gas.

2.    Summary of Significant Accounting Policies

This summary of significant accounting policies is presented to assist the reader in understanding and evaluating the accompanying financial statements. These policies are in conformity with accounting principles generally accepted in the United States and have been consistently applied.

Use of Estimates

The preparation of the financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash equivalents consist of time deposits and other short-term, highly liquid instruments with maturities of three months or less when acquired and are stated at cost, which approximates fair value.

Inventories

Inventories are stated at the lower of cost and market. Cost is determined using the weighted-average method. Elements of cost in inventories include raw materials, direct labor and manufacturing overhead. Any write-downs of inventory are recorded as an adjustment to the cost basis.

F-39

BRC S.R.L.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Property, Plant and Equipment

Property, plant and equipment is stated at cost and depreciated using the straight-line method over the following estimated useful lives:

Buildings	33 years
Machinery and equipment	10 years
Furniture and fittings	5 to 8 years

Impairment of Long-Lived Assets

The Company assesses its long-lived assets (primarily property, plant and equipment) for impairment whenever there is an indication that the carrying amount of the assets may not be recoverable. Recoverability is determined by comparing the estimated undiscounted cash flows expected from these assets to their respective net carrying values. The amount of impairment loss, if any, is measured as the difference between the net book value of the assets and their estimated fair value.

Investments in affiliates

Investments in affiliates which are not majority owned or controlled but for which the Company exercises significant influence are accounted for using the equity method.

Income Taxes

Income taxes provided by each entity are included in the consolidation in accordance with the applicable local laws. Deferred income taxes are accounted for under the liability method, in accordance with SFAS No. 109 Accounting for Income Taxes, and reflect the tax effects of all significant temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements and net operating loss carry-forwards. Valuation allowances are provided against deferred tax assets when it is more likely than not that a tax benefit will not be realized.

Investment tax credits are accounted for as a reduction in current income taxes in the year in which the credit arises.

Foreign Currency Translation

The Company’s reporting currency and functional currency is the Euro. The financial statements of the Company’s subsidiaries are measured using the local currency as the functional currency. With respect to the Brazilian and Argentine subsidiaries, revenues and expenses have been translated into Euros using the average exchange rate for the period and assets and liabilities have been translated using the period-end exchange rate. With respect to the Argentine subsidiary, at December 31, 2001 through January 10, 2002, there was no exchangeability between the Argentine Peso and foreign currencies. On January 11, 2002 when the exchange market first opened, the exchange rate was ARP 1.5 to Euro 1. Under US GAAP, when exchangeability between two currencies is temporarily lacking at the balance sheet date, the first subsequent rate at which exchange could be made shall be used as of the balance sheet date.

The resulting cumulative translation adjustments have been recorded as a separate component of Quotaholder’s equity. Translation adjustments resulting from changes in exchange rates affecting balance sheet and income statement items amount to (losses)/gains of €129, €(64) and €26, for the periods ended December 31, 2001, 2002 and 2003, respectively, and are presented in the Other Comprehensive Income.

F-40

BRC S.R.L.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Realized and unrealized foreign currency transaction gains and losses are included in the determination of net income.

Revenue Recognition

Revenues are recognized on product sales when title transfers, which generally corresponds to the date when products are shipped, and when collectibility is reasonably assured. Provisions for returns and other adjustments related to sales are provided in the same period the related sales are recorded on the basis of historical rates of return.

Research and Development Expenses

Research and development expenses are charged to expense as incurred.

Government Grants

The Company receives grants from Italian governmental entities to subsidize certain investments in plant and equipment and research and development expenditures. Grants are recognized when earned and there is no remaining risk of repayment. There is no remaining risk of repayment when the grant conditions are met or when there is no doubt that these conditions will be met in the future. Grants relating to plant and equipment are recorded as a reduction of the cost of the related assets. Grants relating to research and development expenditure are recorded in other revenues.

During 2001, 2002 and 2003, the Company recognized government grants relating to plant and equipment for nil, €133 and nil, respectively, and relating to research and development expenditure for €31, €507 and €137, respectively.

Statement of Cash Flows

Short-term borrowings arise primarily under the Company’s short-term lines of credit with its banks. These short-term obligations are payable on demand. The cash flows from these items are included under the caption “Net change in short-term borrowings” in the Consolidated Statements of Cash Flows.

Shipping and Handling Costs

Shipping and handling costs on product sales are classified in costs for external services and amount to €454, €373 and €362, for the years ended December 31, 2001, 2002 and 2003, respectively.

In July 2002, the Company sold all its land and buildings to IMCOS2 S.r.l., a real estate investment company controlled by the shareholders of BRC, and to a leasing company, which then leased the land and buildings to IMCOS2 under capital lease arrangements. The portion of these land and buildings that were previously used by BRC were then leased back to BRC under operating lease arrangements. The remaining portion of the land and buildings were previously leased by BRC to a related company and a third party. As the sale-and-leaseback was undertaken between companies under common control, the transaction has been accounted for at historical cost and, consequently, the excess of the sale price over the carrying value of the land and buildings of €221 has been credited to additional paid-in capital.

The terms of the rental agreement between BRC and IMCOS2 S.r.l. require that the Company does not terminate the rental agreement until eight years have expired.

5.    Investments in Affiliates

In February 2001, the Company acquired a 50% stake in MTE S.r.l. for €25. MTE supplies the Company with electronic components for its fuel systems. The amount at which the investment is carried equals the amount of underlying equity in net assets.

In March 2002, the Company acquired a 18.5% stake in Jehin Engineering Company Ltd., a Korean manufacturer of fuel technology systems for €260. In accordance with the share purchase agreement, BRC was able to appoint a member of the Board of Directors. In view of the influence that BRC gained through board membership, the investment has been accounted for using the equity method. The amount at which the investment is carried equals the amount of underlying equity in net assets.

In October 2001, BRC Brasil Ltda. (“BRC Brasil”) signed a joint venture agreement with White Martin Gases Industriais S.A. (“WM”), a Brazilian company and subsidiary of Praxair, Inc., by which BRC and WM (the “joint venture partners”) agreed to establish a joint venture for the development, manufacture and supply of fuel technology systems in the Brazilian market. Pursuant to the agreement, the joint venture partners agreed to invest jointly up to a maximum of US$4 million in the first three years of operations. In May 2002, the joint venture partners gave effect to the joint venture agreement and established WMTM Equipamentos de Gases Ltda. (“WMTM”) owned 50% by each joint venture partner with an initial cash investment of €819. At the same time the joint venture partners established another 50-50 owned company, BRC Gas Equipment Ltda. (“BRCGE”), with the objective of succeeding BRC Brasil in its activity of importation and sale of BRC’s products on the Brasilian market until such time as WMTM had become fully operational. BRC Brasil subscribed to the creation of BRCGE by contributing the inventories and certain other assets for a value of €717. MTM has also provided a bank guarantee to WMTM for an amount of €1,500, which was subsequently reduced to €819. In exchange for

BRC S.R.L.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

entering into the joint venture agreement, BRC Brasil received from WM US$2.2 million. The agreement also required that BRC Brasil pay WM a certain amount in the event that BRCGE failed to achieve a stipulated level of earnings before interest, income taxes, depreciation and amortization, as defined (“EBITDA”). Conversely, WM would pay BRC Brasil if the EBITDA exceeded the stipulated level of earnings before interest, income taxes, depreciation and amortization, as defined. In 2003, the parties agreed that the stipulated level of EBITDA had not been achieved and, accordingly, BRC Brasil paid €98 and recorded this amount as a reduction of the US$2.2 million. The Company has accounted for this transaction in accordance with EITF 01-2 Interpretations of APB Opinion No. 29 and has recognized a partial gain in 2002 of €953, representing 50% of the excess of the fair value of the assets given up over the carrying value of such assets. The remaining 50% has been recorded as a reduction of the carrying value of the Company’s investment in the joint venture companies.

In August 2003 BRCGE ceased operations and in September 2003 was merged into WMTM. The carrying value of the investment in WMTM at December 31, 2003 in the amount of €605 has been classified as an equity investment.

For all the above investments, the amount at which the investment is carried equals the amount of the underlying equity in net assets.

In August 2003, BRC Brasil and WM each made loans to WMTM in the amount of 5,000,000 Real and each company subsequently made additional loans in the amount of 2,000,000 Real. The total of the loans made by BRC Brasil to WMTM of approximately €1,920 have been classified as loans to affiliated companies. The loans are non-interest bearing and are due in January 2005.

6.    Short-Term Borrowings

At December 31, 2003, the Company has an unsecured line of credit amounting to approximately €1,300 with no outstanding balance. Additionally, the Company has up to a €4,500 line of credit secured by customer account receivable drafts, which has current availability of €2,198 and has no outstanding balance. The weighted average interest rate on these short-term borrowings was approximately 3.5% and nil per annum at December 31, 2002 and 2003. The lines of credit are callable on demand.

7.    Income Taxes

A reconciliation between income taxes computed at the Italian statutory tax rate and the effective income tax provision is as follows:

	Year ended December 31, 2001			Year ended December 31, 2002			Year ended December 31, 2003
Income tax provision at the Italian statutory tax rate of 34%	€	93		€	14		€	(278	)

Effective income tax provision	€	783		€	1,037		€	211

The Italian “IRAP” tax is regional tax on productive activities, and has statutory rate of 4.25%. The IRAP tax is not deductible for corporate tax purposes. The IRAP tax base is similar to the corporate tax base, however does not permit a deduction for labor or interest.

The 2001 Italian investment tax incentive law was enacted in order to encourage capital investments in Italy. Companies are able to reduce their taxable income by up to 50% of the excess of new qualifying capital and other expenditures made in the second half of 2001 and in the year 2002 in fixed assets (tangibles and specified intangibles) over the average of the investments made in such assets during the five prior years. The incentive results in a current one time deduction and neither increases nor decreases the tax bases of the assets to compute future tax deductions for depreciation and amortization relating to investment deductions granted. In 2001 and 2003 the Company recognized a benefit from the investment deductions of €375 and €70, respectively.

The components of deferred income tax assets and liabilities at December 31, 2002 and 2003 are:

10.    Employees Severance Indemnities

The liability for severance indemnities relates primarily to the Company’s employees in Italy. The severance indemnity liability is calculated in accordance with local civil and labor laws based on each employee’s length of service, employment category and remuneration. There is no vesting period or funding requirement associated with the liability. The liability recorded in the balance sheet is the amount that the employee would be entitled to if the employee terminates immediately. The charge to earnings was €383, €381 and €391 for the years ended December 31, 2001, 2002 and 2003, respectively.

Rental expense for all operating leases amounted to nil, €122 and €450 in the years ended December 31, 2001, 2002 and 2003, respectively. The major portion of these leases contain renewal options.

13.    Financial Instruments

Off Balance Sheet Risk

The Company does not enter into forward exchange contracts or purchase foreign currency options to hedge firm sales/purchases commitments, anticipated but not yet committed sales/purchases and investments in debt securities denominated in foreign currency.

Concentration of Credit Risks

Financial instruments that potentially subject the Group to concentration of credit risks consist principally of cash investments and trade accounts receivable. The Group maintains cash and cash equivalents and short-term investments with financial institutions located in the various countries in which it operates. The Company selects only financial institutions with high credit standards for use in its investment strategies.

Concentration of credit risks and the risk of accounting loss with respect to trade receivables is generally limited due to the large number of the Company’s end customers. The Company generally does not require collateral with respect to goods and services provided in Italy, but it normally makes sales to foreign customers against secured letters of credit.

The Company’s two largest individual customers accounted for 10.5%, 18.9% and 22%, of net sales for the years ended December 31, 2001, 2002 and 2003, respectively.

Fair Value of Financial Instruments

The following methods and assumptions were used by the Company in estimating its fair value disclosure for financial instruments.

Cash and cash equivalents—The carrying amount of cash and cash equivalents reported by the Company approximates their fair value.

Accounts receivable and payable—The carrying amount of accounts receivable and payable approximates their fair value.

F-48

BRC S.R.L.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Short and long-term debt—The fair value of long-term debt, as of December 31, 2002 and 2003, amounts to approximately €5,507and €934, respectively. The carrying amount of the Company’s other borrowings approximate their fair value. The fair values of the Company’s long-term debt are estimated using cash flow analyses, based on the Company’s incremental borrowing rates for similar types of borrowing arrangements.

14.    Subsequent Events

In January 2004, MTM exercised its put option for the disposal of a 10.5% portion of their shares held in Jehin at a price of €122, which approximates the purchase price net of the change in foreign exchange rate. The ownership of the shares is expected to be transferred in the second half of 2004. No significant gain or loss is anticipated as the put price approximates carrying value.

Section 102(a)(7) of the DGCL permits a provision in the certificate of incorporation of each corporation organized thereunder, such as our company, eliminating or limiting, with certain exceptions, the personal liability of a director of the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. Our Certificate of Incorporation eliminates the liability of each of our directors to our stockholders or us for monetary damages for breach of fiduciary duty to the full extent provided by the DGCL, as such law exists or may hereafter be amended.

Indemnification applies to any threatened, pending or completed action, suit or proceeding, whether, civil, criminal, administrative or investigative.

Item 17.    Undertakings

(a) We 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 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, 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.

(b) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised 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 the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the 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 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.
