                               PROSPECTUS SUMMARY

   You should read the following summary together with the more detailed
information in this prospectus, including risk factors, regarding our company
and the common stock being sold in this offering.

                                  The Company

   We are a leading designer, manufacturer and supplier of fuel storage, fuel
delivery and electronic control systems that allow internal combustion engines
and fuel cells to operate using clean fuels such as hydrogen, propane, natural
gas and methanol. We have designed these systems to optimize efficiency and
performance by electronically sensing and regulating the proper proportion of
fuel and air used by internal combustion engines and fuel cell systems.

   According to Freedonia Group, an independent market research firm, global
demand for vehicles using alternative fuels is expected to grow to 170,000
units annually by the year 2002 from 31,900 units sold in 1997. We believe the
alternative fuel market has grown rapidly in response to environmental concerns
over the pollution caused by internal combustion engines, as well as an
economic incentive to use these fuels due to the price differential between
gasoline and alternative fuels such as natural gas and propane. As gasoline
prices rise, it generally becomes more economical to convert an internal
combustion engine to run on propane or natural gas and benefit from lower fuel
costs. In Mexico, for example, the price of gasoline was more than two times
the price of propane in March 2000. Many countries are also beginning to adopt
alternative fuel technologies in order to lessen their dependence on imported
oil. Based on over 40 years of technology development and expertise in
producing cost-effective, safe and durable alternative fuel systems for
internal combustion engines, we believe that we will be positioned to provide
enabling products and technologies for the rapidly emerging fuel cell industry.

   Fuel cells are devices that produce electricity through an electrochemical
reaction that requires hydrogen as a primary fuel. The newly emerging fuel cell
industry represents an advancement in fuel technologies to address worldwide
concerns over the environment and long-term supply of liquid fuels. The
National Fuel Cell Research Center based at the University of California,
Irvine estimates the market for fuel cell products will exceed $10 billion by
2010. We believe that we can adapt our fuel storage, fuel delivery and
electronic control systems to address the emerging fuel cell market. We also
believe that our technology and equipment that enable fuel cells to run on
hydrogen represent a natural extension of our current product line.

   Our goal is to be the leading provider of fuel storage, fuel delivery and
electronic control systems for fuel cells. We believe that these functions will
represent a critical factor in the commercial viability and market acceptance
of fuel cells. Our enabling technology is targeted to support the
commercialization of the fuel cell being developed by others in the industry.
Regardless of the fuel used in the fuel cell system, we believe the fuel cell
system will require on board storage. We believe our low cost TriShield(TM)
storage tank and advanced fuel delivery and electronic control products are of
special interest to the fuel cell industry because they provide increased fuel
storage at less weight and improved operation through precise and timely fuel
metering.

   We anticipate initially targeting the transportation market, by leveraging
off of our existing technologies for alternative fuel systems as well as our
relationships with OEMs such as General Motors. We also plan to target the
fuel, delivery storage and electronic control system requirements of fuel cells
that are developed for other end markets such as the stationary and portable
power generator markets. We believe our continued success in the design,
manufacturing and commercialization of products for the alternative fuel and
fuel cell industries will depend on our substantial financial commitment to
advanced research and product development and our proven ability to develop and
commercialize products in these industries.

   We were incorporated in Delaware in October 1985. Our principal executive
offices are located at 16804 Gridley Place, Cerritos, California 90703, and our
telephone number at that address is (562) 860-6666.

                                  RISK FACTORS

   Any investment in shares of our common stock involves a high degree of risk.
You should consider carefully the following information about these risks,
together with the other information contained in this prospectus, before you
decide to buy our common stock. If any of the following risks actually occur,
our business, results of operations and financial condition would likely
suffer. In these circumstances, the market price of our common stock could
decline, and you may lose all or part of your investment.

We may never complete the research and development of commercially viable fuel
metering, fuel storage or control products for fuel cell systems.

   We do not know when or whether we will successfully complete the research
and development of a commercially viable fuel metering, fuel storage or control
products for the fuel cell market. We have produced and are currently
demonstrating a number of test and evaluation systems and are continuing our
efforts to decrease the costs of our systems' components and subsystems,
improve their overall reliability and efficiency, and ensure their safety.
However, we must complete substantial additional research and development on
our systems before we will have a commercially viable fuel delivery system for
fuel cells. Even if we are able to do so, our efforts will still depend upon
the success of other companies producing commercially viable fuel cells. In
addition, we are not currently manufacturing fuel cell enabling products on a
large scale basis and will need to upgrade existing facilities to do so. In
particular, the manufacturing of our TriShield(TM) composite tank may not be
successful and could have an adverse impact on our growth in fuel cell enabling
technologies.

A mass market for fuel metering, fuel storage and control systems for fuel
cells may never develop or may take longer to develop than we anticipate.

   Fuel cell systems represent an emerging technology, and we do not know
whether OEMs will incorporate these technologies into their products or pursue
these technologies on a large scale basis. In particular, if a mass market
fails to develop or develops more slowly than we anticipate for fuel cell
powered automobiles and equipment, we may be unable to recover the expenditures
we will have incurred to develop our fuel systems for fuel cells and may be
unable to achieve profitability in that portion of our business. Many factors
which are out of our control may have a negative effect on the development of a
mass market for our fuel cell products and systems. These factors include:

  . the cost competitiveness and size of fuel cell systems;

  . the availability, future costs and safety of hydrogen, natural gas or
    other potential fuel cell fuels;

  . consumer reluctance to adopt alternative fuel products;

  . OEM reluctance to replace current technology;

  . consumer perceptions of fuel cell systems;

  . regulatory requirements; and

  . the emergence of newer, breakthrough technologies and products by our
    competitors in the fuel cell industry.

Our Automotive OEM divisions revenues are heavily dependent on our relationship
with General Motors and General Motors' commitment to develop the alternative
fuel market.

   Nearly all of our revenues for the fiscal year ended April 30, 1999 for our
Automotive OEM division and 28.2% of our total revenues for the same period
related to sales of our products to and contracts with General Motors. Our
Teaming Agreement with General Motors terminates on July 30, 2002 and may be
earlier terminated unilaterally by either us or General Motors upon 30 days
written notice upon certain events including:

  . lack of a meeting of the management committee created under the terms of
    the Teaming Agreement for 18 consecutive months; or

                                       7
<PAGE>

  . a material breach of the Teaming Agreement which remains uncorrected for
    20 days following notice.

   Additionally, General Motors may terminate the Teaming Agreement in the
event we change our management or ownership control. Our business and results
of operations would be adversely affected in the event General Motors
terminates its relationship with us or ceases to pursue the alternative fuel
market.

   Our ability to sell our products to the automotive market is heavily
dependent upon General Motors' worldwide sales and distribution network and
service capabilities. Any change in our relationship with General Motors could
harm our potential earnings by reducing or eliminating a substantial portion of
our sales, whether as a result of market, economic or competitive pressures,
including any decision by General Motors:

  . to alter its commitment to our fuel metering, fuel storage and control
    technology in favor of other competing technologies;

  . to develop alternative fuel systems targeted at different markets than
    ours; or

  . to focus on different energy product solutions.

   We have submitted products for testing and have responded to requests for
proposals from a number of other potential customers. To date, none of these
proposals have resulted in any long-term commitments. Additionally, our
contract provides for a non-exclusive right of first refusal to General Motors
on jointly developed products.

We intend to make significant investments in fuel cell enabling technologies,
which may not result in any corresponding increase in net revenues.

   We anticipate that our investment in research and development will
significantly increase as we focus our efforts in developing fuel cell enabling
technologies. As we pursue this business strategy, we expect to incur operating
losses driven by research and development expenditures for at least the next 12
months. In particular, we plan to use a substantial portion of the net proceeds
from this offering to fund this effort. We may not recover this investment.

We may be unable to raise additional capital to complete our product
development and commercialization plans.

   We currently anticipate that we will need to raise additional funds to
complete the development and commercialization of our fuel cell enabling
technologies. These funds may not be available on acceptable terms, if at all.
Our product development and commercialization schedule could be delayed if we
are unable to fund our research and development activities or the development
of our manufacturing infrastructure for new products. We expect that the net
proceeds of this offering and all other existing sources of capital will be
sufficient to fund our activities through the end of calendar year 2001. We are
receiving limited proceeds from this offering and will need to raise additional
funds to achieve full commercialization of our fuel storage and delivery
systems for fuel cells. We do not know whether we will be able to secure
additional funding or funding on terms acceptable to us and, if so, we may not
be able to pursue our commercialization plans through the mass market stage.

Our business depends on the growth of the alternative fuel market.

   The alternative fuel market has not yet gained broad acceptance and our
future success depends on the expansion of this market. Substantially all of
our revenue for the fiscal year ended April 30, 1999 was derived from sales of
products and enabling technologies for use in the alternative fuel market. In
the United States and certain of our other target markets, alternative fuel
such as natural gas cannot be readily obtained by consumers for motor vehicle
use and only a small percentage of motor vehicles manufactured in 1999 were
equipped to use alternative fuels. We cannot assure you that the market for
gaseous alternative fuel engines will gain broad acceptance or, if this growth
does occur, that it will result in increased sales of our advanced fuel system
products. In addition, we have designed many of our products for alternative
fueled vehicles powered by internal combustion engines or fuel cells, but not
currently for alternative power sources such as electricity or alternate forms
of existing fuels. If the major growth in the alternative fuel market is solely
for existing fuels, our revenues may not increase or may decline.

                                       8
<PAGE>

Users of gaseous alternative fueled or fuel cell powered 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 run primarily on
natural gas or propane. Fuel cells run on hydrogen or reformed fuels containing
hydrogen. Gasoline, the only fuel that is currently readily available in most
of the world, requires the development of additional technologies for its use
with fuel cells. The construction of a system to deliver natural gas, propane
or hydrogen, or a suitable fuel containing hydrogen, requires significant
investment by third parties. We cannot guarantee you that an adequate fuel
distribution infrastructure will be built for mass adoption. We are relying on
third parties, most of whom are heavily 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 or fuel cells is unlikely to develop.

   Our ability to successfully attract customers and sell products is also
dependent on the current price disparity between liquid fuels such as petroleum
and gasoline, and gaseous fuels such as propane and natural gases. There can be
no assurance that this price disparity will continue. Should this disparity
narrow or disappear, it could adversely affect the demand of our products.

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

   We currently compete with companies who manufacture products for current
power technologies to convert engines operating on liquid fuels to gaseous
fuels and for new alternative power technologies, including types of fuel cells
that may not require metering, storage or control products of the type we
design and produce.

   As the market for alternative fueled vehicles increases, OEMs may find it
advantageous to develop and produce their own fuel conversion or fuel
management equipment rather than purchasing the equipment from suppliers such
as ourselves. In addition, as the fuel cell market gains greater acceptance, it
is likely that there will be new competitors in our current markets. Should
either 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 our plans to market, distribute and service our
products internationally.

   We currently operate in Europe, Australia, Mexico and Japan, 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:

  . exposure to currency fluctuations;

  . the inherent difficulty of staffing and managing potential difficulties
    in enforcing contractual obligations and intellectual property rights;
    and

  . the burden of complying with a wide variety of laws and regulations
    including product certification, environmental and import and export
    laws.

   Any significant increase in the value of the dollar against foreign
currencies where we do business may impact negatively our competitiveness in
international markets.

                                       9
<PAGE>

   We also intend to manufacture, market, distribute and service our fuel
delivery systems for fuel cell powered equipment and vehicles internationally.
We have limited experience developing, and no experience manufacturing these
products to comply with the commercial and legal requirements of international
markets. Our success in these markets will depend, in part, on our ability to
secure relationships with foreign OEMs and our ability to manufacture products
that meet foreign regulatory and commercial requirements.

Our business may be subject to product liability claims, which could be
expensive and could result in a diversion of management's attention.

   The automotive industry in the past has experienced significant product
liability claims. As a supplier, we face an inherent business risk of exposure
to product liability claims in the event that our products or the equipment
into which our products are incorporated malfunction resulting in personal
liability or death. We may be named in these actions even if there is no
evidence that our systems or components caused the accident. Product liability
claims could result in significant losses as a result of expenses incurred in
defending claims and as a result of damage awards. The sale of systems and
components for the transportation industry entails a high risk of such claims.
In addition, if any of our systems prove to be defective, we may be required to
participate in a recall involving such systems, or due to various industry or
business practices or the need to maintain good customer relationships, we may
voluntarily initiate a recall or make payments related to such claims. We
cannot assure you that our current 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 business may become subject to future product certification regulations
which may impact 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 primary 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
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.

   We anticipate that regulatory bodies will establish certification procedures
and will impose regulations on our fuel cell enabling technologies, which may
impact our ability to distribute, install and service these systems. Any new
government regulation of our advanced fuel technologies, whether at the United
States or 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 such, these regulations may have a negative
impact on our revenue and profitability, and accordingly, 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. We believe that
our future success depends upon our ability to design, develop and market new
or modified fuel delivery, fuel storage and electronic control products for
internal combustion engines and fuel cell systems. Our ability to enhance
existing products in a timely manner and 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.

                                       10
<PAGE>

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,
confidentiality agreements and, if applicable, inventors rights agreements with
our employees, customers, partners and others to protect our intellectual
property for our alternative fuel and fuel cell enabling technologies. 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 currently have over 30 patents outstanding which will expire between
November 2001 and October 2018. We also have two patent applications
outstanding in our fuel cell enabling technology. We do not know whether any of
our pending patent applications will issue or, in the case of patents already
issued or to be issued, that the claims allowed will be sufficiently broad to
protect our technology or processes. Even if all our patent applications are
issued and are sufficiently broad, they 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. It may
be difficult for us to enforce certain of our intellectual property rights
against third parties who may have acquired intellectual property rights by
filing unauthorized applications in foreign countries to register the marks
that we use because of their familiarity with our worldwide operations.

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

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

   We have established relationships with third party suppliers, upon whom we
rely to provide materials and components for our products, particularly the
high strength fiber used in our light weight hydrogen tanks. 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,
or our inability to obtain substitute sources for these materials and
components in a timely manner or on terms acceptable to us, could harm our
ability to manufacture our products or could significantly raise our cost of
producing our products. In particular, a delay in the delivery of high strength
fiber from our current sole suppliers could result in a delay of the production
of our products for up to three months, which could negatively impact our
results of operations and business.

We may have difficulty managing the expansion of our product line to fuel cell
enabling technologies.

   We currently anticipate a rapid expansion with respect to the development of
our fuel cell enabling technologies. This expansion will require us to hire
additional employees, increase the size of our current facilities and expand
the scope of our operations, and is likely to place a significant strain on our
management team and other resources. Difficulties in effectively managing the
budgeting, forecasting and other processing control issues presented by this
rapid expansion could harm our business, prospects, results of operations or
financial condition.

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

   Our revenues and operating results are subject to annual and quarterly
fluctuations as a result of a variety of factors, including, without
limitation:

  . budget cycles and funding arrangements of governmental agencies;

  . purchasing cycles of fleet operators;

                                       11
<PAGE>

  . the uncertainty of timing of deliveries of vehicles to be equipped;

  . the timing of implementation of government regulations promoting
    alternative fuel vehicles; and

  . general economic factors.

   It is possible that in one or more future quarters our operating results may
fall below the expectations of securities analysts and investors. If this
happens, 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 and our affiliates' ability to
attract and retain key management, engineering, scientific, manufacturing and
operating personnel, particularly Robert M. Stemmler, our President and Chief
Executive Officer, Dale L. Rasmussen, our Senior Vice President and Secretary,
and Syed Hussain, our Vice President of Technology and Automotive OEM division.
As we develop our fuel cell business, we will require more technically skilled
personnel. Recruiting personnel for the industries in which we are positioned
is highly competitive and the failure to attract or retain qualified personnel
could have a material adverse effect on our business.

Our failure to meet OEM specifications may hurt our business.

   In 1993, we began to offer complete, integrated alternative fuel systems,
which include tanks, brackets, electronics, software and all other engine
components required to convert a motor vehicle to alternative fuels. Customers
for these systems require that they meet OEM standards. These requirements have
resulted in increased development, manufacturing, warranty and administrative
costs. If these costs increase significantly, our profitability could be
adversely affected. Our inability to meet OEM specifications at all, or on a
timely basis, may hurt our relationships with OEMs.

We may be subject to increased warranty claims.

   In response to consumer demand, vehicle manufacturers have been providing
and may continue to provide increasingly longer warranty periods for their
products. As a consequence, these manufacturers require their suppliers, such
as us, to provide correspondingly longer product warranties. As a result, 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
become increasingly dependent on OEM production and the associated labor forces
at OEM sites. Labor unions represent most of the labor force at OEM facilities.
Labor disputes could occur at OEM facilities and could adversely impact our
direct OEM product sales. For example, in 1998, as a result of a strike at one
of our OEM's facilities, we experienced a decline in sales of General Motors
pick-up trucks.

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

   The market for alternative fueled vehicles and equipment, and the demand for
our products are, to a significant degree, driven by local, state and federal
regulations in the United States related to air quality and requiring purchase
of motor vehicles and equipment to operate on alternative fuels. Our
international business is also affected by similar foreign governmental
regulations. These laws and regulations may change. Changes in these laws and
regulations could result in transportation or equipment manufacturers
abandoning their interest in alternative fueled and fuel cell powered vehicles.
In addition, a failure by authorities to enforce current domestic and foreign
laws or to adopt further environmental laws could limit demand for our
products.

                                       12
<PAGE>

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

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

   The stock market has, from time to time, experienced price and volume
fluctuations. Many factors may cause the market price for our common stock to
decline, perhaps substantially, following this offering, including:

  . failure to meet our product development and commercialization milestones;

  . demand for our common stock;

  . revenues and operating results failing 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 volatility in the market price
of their stock have been the subject of securities class action litigation. We
may be involved in a securities class action litigation in the future. This
litigation often results in substantial costs and a diversion of management's
attention and resources and could harm our business, prospects, results of
operations or financial condition.

Provisions of Delaware law and of our charter and by-laws may make a takeover
more difficult.

   Provisions in our certificate of incorporation and by-laws and in the
Delaware corporate law may make it difficult and expensive for a third party to
pursue a tender offer, change in control or takeover attempt which our
management and Board of Directors oppose. Public stockholders who 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.

   In June 1999, we entered into a Stockholder Protection Rights Agreement
which provided for a dividend of one right for each outstanding share of our
common stock. Each right entitles the holder to purchase one share of our
common stock at an exercise price of $45.00 per share. 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 the exercise
price, common stock with a 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 the Company and 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 in the public market following this offering, 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 capital in the
future. After this offering, we will have 10,196,805 shares of common stock
outstanding. Of these shares, the 2,500,000 shares sold in this offering will
be freely tradeable. Of the remaining 7,696,805 shares, 4,823,080 shares which
are

                                       13

currently freely tradeable will remain freely tradeable, 2,873,725 shares will
be subject to 135 day lock-up agreements. In addition, up to 1,321,931 shares
issuable upon the exercise of outstanding options may become available for sale
in the public markets. The holders of 1,115,326 shares subject to the 135 day
lock-up agreement have the right to require us to register some or all of those
shares for sale after the expiration of the 135 day period. However, even if
the holders do not require registration, the holders may sell a portion of
their shares under the exemption afforded by Rule 144 promulgated by the
Securities and Exchange Commission following the expiration of the 135 day
period. The 135 day lock-up period may be shortened upon agreement by the
underwriters. We cannot predict if future sales of our common stock, or the
availability of our common stock for sale, will harm the market price for our
common stock or our ability to raise capital by offering equity securities.

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

                                USE OF PROCEEDS

   Our net proceeds from the sale of the 1,625,000 shares of common stock
offered by us, after deducting estimated underwriting discounts and commissions
and estimated expenses payable by us, are estimated to be approximately $44.4
million ($54.8 million if the underwriters' over-allotment option is exercised
in full). We plan to use a portion of these net proceeds to repay indebtedness
under our outstanding revolving lines of credit and term loans. At March 31,
2000, approximately $25 million was outstanding under these obligations at
weighted average interest rate of 7.5% per annum. We anticipate the balance of
these proceeds will be used for the expansion of our development engineering
capabilities and general corporate purposes including research and development
in fuel cell technologies and working capital. We currently have no commitments
or agreements with respect to any material acquisitions. Pending use of the net
proceeds, we plan to invest the net proceeds of this offering in short-term
investment grade securities. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations." We will have broad discretion
as to the allocation and use of the net proceeds that we will receive.

                                DIVIDEND POLICY

   We previously paid the holders of our 1993 Series 1 Preferred Stock
cumulative cash dividends. 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

   You should read this discussion together with the financial statements and
other financial information included in this prospectus.

Overview

   We are a global supplier of fuel delivery, storage and electronic control
systems for internal combustion engines and fuel cells. Historically, most of
our revenues have been derived from the sale of these products that enable
traditional internal combustion engines to run on clean burning alternative
fuels such as propane and natural gas instead of gasoline. Our future goal is
to commercialize systems that will provide delivery, storage and electronic
controls for fuel cells.

   We classify our business interests into three operating segments: Automotive
OEM division, Gaseous Fuel Products division and International Operations. The
Automotive OEM division generates revenues through the sale of fuel delivery,
storage and electronic control systems to OEMs, primarily General Motors and
the installation of our products into OEM vehicles. The division also generates
contract revenue by providing engineering design and support to the OEMs so
that our fuel system will fit into a variety of their vehicles as they upgrade
their models each year. The Gaseous Fuel Products division sells products
including parts and conversion systems to OEMs and the aftermarket. Our
International Operations in Australia, Europe, Japan and Mexico provide
distribution for our products, predominantly from our Gaseous Fuel Products
division and some product assembly.

   We will require significant research and development expenditures over the
next several years in order to commercialize our products for fuel cell
applications. We will also require significant capital expenditures to
construct additional manufacturing and assembly capacity required to support
the production of our products.

   We recognize revenue for product sales when products are shipped and title
is transferred. Contract revenues are recorded based on the percentage of
completion method. Corporate expenses represents a sub-category of selling,
general and administrative expense. Corporate expenses consist of general and
administrative expense incurred at the corporate level and includes the
amortization of goodwill and other intangible assets. Intersegment eliminations
are primarily the result of intercompany sales from our Gaseous Fuel Products
division to our International Operations segment. End markets for our products
include the transportation, material handling, and industrial and power
generation industries.

   All research and development is expensed as incurred. Research and
development expense includes both customer funded research and development and
company sponsored research and development. Corporate research and development
is a sub-category of research and development expense and represents company
sponsored research and development that is not allocated to any of our
operating segments. Customer funded research and development consists primarily
of expenses associated with contract revenue. These expenses include
applications development costs in the Automotive OEM division funded under
customer contracts.

Acquisitions

   A portion of our growth over the past three years, particularly with regard
to our international operations, has resulted from acquisitions in Australia,
Canada, Europe, Japan, Mexico, the United States and the formation of a
European based joint venture. We have accounted for each of these acquisitions
under the purchase method of accounting.

   Australia. In July 1996, we acquired certain assets of Ateco Automotive Pty.
Limited, including a 50.0% ownership interest in Gas Parts (NSW) Pty., for a
purchase price of approximately $6.5 million. Ateco is an Australian based
company that provides conversion services to OEMs. Gas Parts is an Australian
based distributor of aftermarket gaseous fuels conversion equipment. In January
1998, we acquired the remaining

                                       20
<PAGE>

50.0% ownership interest in Gas Parts. The consolidated revenues of our
Australian subsidiary, which we refer to as IMPCO Australia, totaled
approximately $7.8 million for ten months of operations in fiscal year 1997,
$6.9 million in fiscal year 1998 and $5.4 million in fiscal year 1999.

   Mexico. In December 1997, we purchased certain manufacturing equipment and
inventory of the Algas Carburetion division of PGI International at a purchase
price of approximately $2.4 million. Prior to its acquisition, the Algas
Carburetion division manufactured and sold carburetion equipment for gaseous
fuels. On the same day, we acquired a 90.0% interest in Industrias Mexicanas de
Productos de Combustibles, S. de R.L. de C.V., a Mexico City based distributor
of the Algas Carburetion division products. The purchase price was $961,000. We
combined these interests to form our Mexican subsidiary, Groupo I.M.P.C.O.
Mexicano, S. de R.L. de C.V. Our Mexican subsidiary had revenues of
approximately $823,000 for five months of operations in fiscal year 1998 and
$2.7 million in fiscal year 1999.

   Canada. In December 1997, we purchased from the bankruptcy trustee of EDO
Canada, Ltd. certain development, testing, quality control and manufacturing
equipment used for the manufacture of storage tanks for compressed natural gas.
The purchase price was $790,000. Since the acquisition, we have relocated this
equipment to our Irvine, California facility.

   Europe. In May 1998, we acquired the remaining 49.0% interest in IMPCO
Technologies, B.V, a European distributor of our products. The purchase price
was $692,000. On January 28, 1999, we sold a 49.0% interest in IMPCO B.V. to
BERU Aktiengesellschaft, an international OEM and aftermarket supplier of
diesel and automotive engine components and systems, for $3.5 million in cash.
We recorded a pre-tax gain of $2.2 million and an after-tax gain of $1.8
million, or $0.20 per diluted share. We operate the new company as IMPCO-BERU
Technologies, B.V. Revenues of this majority owned subsidiary were
approximately $9.2 million in fiscal year 1997, $11.6 million in fiscal year
1998 and $12.9 million in fiscal year 1999.

   United States. In December 1998, we acquired certain assets of the Crusader
Engine division of Thermo Power Corporation, a subsidiary of Thermo Power
Electron Corporation, for approximately $3.9 million. The Crusader Engine
division, which is now our Industrial Engine Systems business, provides engine
dressing and related devices for material handling, irrigation and other
industrial engines. Engine dressing involves the acquisition of basic engine
mechanical parts from an OEM and adding fuel handling and other parts to make
the engine fully functional. We are amortizing goodwill of approximately
$662,000 on the straight-line method over 20 years. Tangible net assets
acquired consisted of $2.5 million in inventory and $718,000 in fixed assets.
Our Industrial Engines Systems business had revenues of approximately $3.2
million for the five months of operations in fiscal year 1999.

   Japan. In March 1999, we acquired certain assets of the alternative fuels
division of Mikuni Corporation for approximately (Yen)158,629,000 (US $1.3
million). The alternative fuels division, based in Fukuoka, Japan, is a
distributor of alternative fuels products and systems throughout Asia, with a
focus on the Japanese market. Mikuni had distributed our products in Japan
since 1994. We are amortizing goodwill of approximately (Yen)113,016,000 (US
$944,000) on the straight-line method over 20 years. The tangible net assets
acquired consisted of $362,000 in inventory and $19,000 in fixed and other

month of operation in fiscal year 1999 were approximately $178,000.

   Net revenue increased $23.6 million or 39.4% from $60.1 million for the nine
months ended January 31, 1999 to $83.7 million for the nine months ended
January 31, 2000. This increase was primarily due to strong aftermarket sales
in all end use applications and a 23.1% increase in General Motors product
sales. The following table sets forth our product revenues by application

   Automotive OEM Division. Net revenues decreased $1.4 million or 8.5% from
$6.9 million for the nine months ended January 31, 1999 to $15.4 million for
the nine months ended January 31, 2000.

   Product sales for this division increased $1.6 million or 23.1% from $6.9
million for the nine months ended January 31, 1999 to $8.5 million for the nine
months ended January 31, 2000. During the nine months ended January 31, 2000,
product sales represented 2,071 units as compared to 1,787 units during the
same period of the prior year. Product sales consists of General Motors mid-
size automobiles and pick-up trucks equipped with this division's bi-fuel
compressed natural gas fuel system and dedicated liquid propane gas kits under
the Teaming Agreement with General Motors for their medium duty trucks. We
expect product sales to be higher in the future as additional General Motors
platforms and model years are introduced and other automotive OEM platforms are
obtained.

   Contract revenue for this division decreased $3.1 million or 30.3% from
$10.0 million for the nine months ended January 31, 1999 to $6.9 million for
the nine months ended January 31, 2000. This decrease was primarily a result of
lower contract levels attributable to our ability to transfer knowledge between
prior model year and current model year contracts and, accordingly, lower
margins on the current year contracts. We anticipate, based on new contracts
negotiated with General Motors and expected levels of contract completion in
fiscal year 2000, that contract revenue in fiscal year 2000 will be lower than
levels experienced during fiscal year 1999. Additionally, profit levels
expected on the contracts during fiscal year 2000 will be substantially lower
than levels realized during fiscal year 1999.

                                       22

   Operating income (losses) in the division decreased $3.2 million or 191.8%
from $1.7 million in the nine months ended 1999 to ($1.5) million for the nine
months ended January 31, 2000. This decrease was a result of lower contract
revenues, primarily from the General Motors program, and associated higher
product application development costs for new products being commercialized.
Product application development expense is primarily for system development and
application engineering of our products under the Teaming Agreement, other
funded contract work with state and federal agencies, and for company funded
product and component application development work to develop business with
other automotive OEMs. For the nine months ended January 31, 2000, expense
directly related to customer funded product application development work was
approximately $4.2 million as compared to $4.9 million in the same period of
the prior fiscal year. We anticipate higher operating losses in this division
in fiscal year 2000, primarily due to lower profits on General Motors contracts
and higher company funded application development work.

   Gross margins on General Motors product sales were higher in the first nine
months ended April 30, 2000 as compared to the same period in fiscal year 1999,
primarily due to lower raw material costs and lower per unit overhead costs. We
anticipate higher gross margins on products in future model years, primarily
due to engineering design and lower per unit overhead costs.

   Gaseous Fuel Products Division.  Net revenues in this division increased
$21.9 million or 60.4% from $36.3 million for the nine months ended January 31,
1999 to $58.2 million for the nine months ended January 31, 2000. This increase
was primarily a result of the December 1998 acquisition of the Industrial
Engine Systems business, an increase in small engine sales and an increase in
product sales to Mexico. The price differential between gasoline and propane as
well as our strengthening relations with Mexican governmental agencies have
positively impacted the demand for the aftermarket automotive conversions in
Mexico. We anticipate that overall revenues generated by the Gaseous Fuel
Products division in fiscal year 2000 will be higher than fiscal year 1999,
primarily due to a full year reporting sales by our Industrial Engine Systems
business, the expanding revenue base from value added system sales, increased
motor vehicles sales in Mexico due to the expected growth of aftermarket
automotive conversions, and increased small engine sales and our marketing
efforts to expand market share.

   Operating income in this division increased approximately $5.5 million or
54.5% from $10.1 million for the nine months ended January 31, 1999 to $15.7
million for the nine months ended January 31, 2000 as compared to the same
period in the prior fiscal year. This increase was primarily attributable to
higher revenues and gross profit on the Gaseous Fuel Products division product
sales due to increased volumes. This increase was partially offset by
additional administrative expenses resulting from the Industrial Engine Systems
business acquisition. We anticipate that divisional operating income will be
higher in fiscal year 2000 as a result of higher revenues and gross profit
associated with increased volumes partially offset by increased expenses
relating to a full year reporting of the Industrial Engine Systems business and
expenses relating to marketing efforts. Additionally, we anticipate that
operating margins will be affected by lower gross margins at the Industrial
Engine Systems business as these revenues become a larger segment of the
Gaseous Fuel Products division. However, as the Industrial Engine Systems
business increases, we expect overall gross profit will increase.

   International Operations. Net revenues in this division increased by
approximately $6.0 million or 37.7% from $15.9 million for the nine months
ended January 31, 1999 to $21.9 million for the nine months ended January 31,
2000. This increase was primarily a result of the March 1999 acquisition of
IMPCO Japan, which resulted in increased revenues of approximately $2.3 million
in the nine months of fiscal year 2000. During the nine months ended January
31, 2000, this segment also realized increased revenues of $2.6 million from
our Mexico operations. For the nine months ended January 31, 2000, revenues for
our International Operations segment would have increased an additional
$152,000, if not for the strengthening of the U.S. Dollar. A strong U.S. Dollar
negatively impacts the conversion of foreign currency denominated sales. We
anticipate that revenues for this segment during fiscal year 2000 will be
higher than fiscal year 1999 as a result of the acquisition of IMPCO Japan and
higher motor vehicle sales in Mexico. The price differential between gasoline
and propane, as well as our strengthening relations with Mexican governmental
agencies is expected to positively impact the demand for the aftermarket
automotive conversions in Mexico.

                                       23
<PAGE>

   Operating income for this division increased $1.6 million or 200.6% from
$782,000 for the nine months ended January 31, 1999 to $2.4 million for the
nine months ended January 31, 2000. This increase was primarily due to the
addition of our Japan operations. We anticipate that operating income levels in
our International Operations segment will be higher in fiscal year 2000 than in
the prior year due to the addition of the Japan operations and higher revenues
from Mexico.

   Corporate Expenses. Corporate expenses consists of general and
administrative expenses at the corporate level to support us and our divisions
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 is recorded as a corporate
expense. Corporate expenses increased $1.1 million or 27.7% from $4.0 million
for the nine months ended January 31, 1999 to $5.1 million for the nine months
ended January 31, 2000. The increase in corporate expenses was primarily due to
the incremental costs incurred in the creation of our Stockholder Protection
Rights Agreement, legal expenses and amortization of goodwill related to the
Japan and the Crusader acquisitions. We anticipate that corporate expenses
during fiscal year 2000 will be higher than levels experienced during fiscal
year 1999.

   Corporate Research and Development. Corporate research and development
provides engineering, design and research and development support to us and our
operating units and develops all new products supporting the operating
divisions' needs. Corporate research and development increased $2.2 million or
103.4% from $2.1 million for the nine months ended January 31, 1999 to $4.3
million for the nine months ended January 31, 2000. This increase is primarily
due to increased efforts relating to the development and commercialization of
fuel metering, storage and fuel systems for fuel cells. We believe our future
success depends on our ability to design, develop and market new products that
interface successfully with new engine electronic technology, and which meet
mandated emission standards. We also believe that there is a significant
opportunity for us to participate in the emerging fuel cell market. With the
emergence of fuel cell technology and the interest being shown by the
automotive industry, we have decided to accelerate and expand both research and
development expenditures for fuel storage, fuel metering and electronic
controls for fuel cell applications. Consequently, we anticipate that corporate
research and development during fiscal year 2000 will be significantly higher
than in fiscal year 1999.

   Interest Expense. Interest expense increased $234,000 or 25.8% from $905,000
for the nine months ended January 31, 1999 to $1.1 million for the nine months
ended January 31, 2000. This increase was attributable to additional borrowings
partially offset by lower interest rates on our current credit facility with
Bank of America. We anticipate that interest expense for fiscal year 2000 will
be higher than levels experienced during fiscal year 1999, primarily due to
increased borrowings related to our acquisitions.

   Provision For Income Taxes. The estimated effective annual tax rate of 26.0%
for fiscal year 2000 is higher than the previous year due to the exhaustion of
federal net operating loss carryforwards during the previous fiscal year. The
current year tax provision includes presumed utilization of estimated research
and development credits of $859,000. At January 31, 2000, net deferred tax
asset was approximately $3.5 million while the net deferred tax liability was
$566,000. We have determined, based on our history of prior operating earnings
and our expectations for the future, that our operating income will more likely
than not be sufficient to recognize fully the net deferred tax assets and that
the estimated effective annual tax rate in the future years will approximate
the statutory rate.

   Automotive OEM Division. Net revenues in this division increased $12.2
million or 98.5% from $12.3 million in fiscal year 1998 to $24.5 million in
fiscal year 1999. This increase was the result of higher motor vehicle direct
OEM product revenue, which increased to $13.5 million from $3.7 million in
fiscal year 1998. This represents an approximate 264.9% increase in General
Motors product revenue. During fiscal year 1999, the General Motors product
revenue represented 3,300 units consisting of mid-size automobiles and pick-up
trucks equipped with this division's bi-fuel compressed natural gas fuel
system, and dedicated liquid

                                      25
<PAGE>

propane gas kits under a Teaming Agreement with General Motors for their medium
duty trucks. During fiscal year 1998, the General Motors product revenue
represented sales of 1,320 units consisting of General Motors pick-up trucks
equipped with this division's bi-fuel natural gas fuel system and dedicated
liquid propane gas kits under a Teaming Agreement with General Motors for their
medium duty trucks.

   Contract revenues for this division increased $2.4 million or 27.9% from
$8.6 million in fiscal year 1998 to $11.0 million in fiscal year 1999. This
increase was primarily attributable to the addition of several vehicle
platforms and additional future model years for existing platforms under the
General Motors development contract and development contracts funded by the
Southern California Air Quality Management District. Contract revenue is
principally recognized by the percentage of completion method. Profits expected
to be realized on contracts are based on our estimates of total contract sales
value and costs at completion. These estimates are reviewed and revised
periodically throughout the lives of the contract.

   Operating losses for this division decreased $1.4 million or 98.1% from $1.5
million for fiscal year 1998 to $27,000 in fiscal year 1999. This decrease was
primarily due to higher contract revenues, principally from the General Motors
program, and associated lower product application development costs for new
products being commercialized. Product application development expense is
primarily for system development and application engineering of our products
under the General Motors Teaming Agreement and other customer funded contract
research and development work with the Southern California Air Quality
Management District and other agencies, and for company funded product and
component application development work. Research and development expense
directly related to customer funded product application development work
decreased from $7.4 million in fiscal year 1998 to $6.1 million in fiscal year
1999. These decreases are a result of improved productivity resulting from
knowledge transfer over multiple platforms and application of knowledge to non-
General Motors funded contracts. Research and development expense directly
related to company funded product application development work decreased
approximately $200,000 as compared to fiscal year 1998. This decrease is a
result of efficiencies realized in developing new advanced technology and
products.

   The decrease in operating losses as a result of higher contract revenues was
nearly offset by lower gross margins on the General Motors product sales,
compared to the prior fiscal year. During fiscal year 1999, the division
experienced negative material usage variances and increased fixed overhead
costs not covered by production volumes for several new start-up OEM programs.

   Gaseous Fuel Products Division. Net revenues for this division increased
$4.3 million or 8.9% from $48.3 million in fiscal year 1998 to $52.6 million
for fiscal year 1999. This increase was primarily a result of the current year
addition of the Industrial Engine Systems business, higher revenues from the
small engine market and higher transfer sales to support the increased sales
levels of the subsidiaries. For fiscal year 1999, the increase in the small
engine market resulted from higher demand for small portable engines generators
as consumers and small business prepared for the Year 2000. These increases
were partially offset by lower revenues from the large stationary engine market
where net revenues decreased from $3.3 million in fiscal year 1998 to $2.3
million in fiscal year 1999. This decrease was primarily a result of reduced
demand for large power generation units used in power replacement and
recreational applications and other heavy duty applications, particularly in
Asia.

   Operating income for this division decreased $465,000 or 3.2% from $14.7
million in fiscal year 1998 to $14.3 million in fiscal year 1999. This decrease
was primarily due to higher sales and administrative expenses, primarily from
additional marketing and technical support expenses to support the higher
sales. Additionally, this division's company funded product application
development costs increased from $1.3 million in fiscal year 1998 to $1.5
million in fiscal year 1999. These amounts were partially offset by higher
gross profits as a result of higher sales volumes, although the percent margin
decreased from 38.9% to 37.1% as a result of anticipated lower margins realized
on the system sales from IMPCO Europe. Additionally, customer funded research
and development expense decreased by $263,000 in fiscal year 1999.

   International Operations. Net revenues for this segment increased $1.9
million or 9.8% from $19.3 million in fiscal year 1998 to $21.2 million in
fiscal year 1999. International Operations revenues would have increased an
additional $1.1 million if not for the strengthening of the U.S. Dollar. A
strong U.S. Dollar negatively impacts the conversion of foreign currency
denominated sales. During fiscal year 1999, we realized increased revenues of
$1.4 million from our European operations, which primarily sells material
handling components. Additionally, our Mexican operations, acquired in December
1997, reported a full year of revenues of $2.7 million compared to $823,000 in
revenues for the five month period in fiscal year 1998. These increases were
partially offset by a $1.4 million decrease in revenues from our Australian
operations which primarily sells motor vehicle components. Without the
strengthening of the U.S. Dollar, revenues from Australian operations would
have decreased to less than half this amount in fiscal year 1999. We believe
the lower product sales from our Australian operations were a result of a
continued general economic slowdown in Asia, a decrease in component sales to
OEMs and unfavorable price differentials between propane and gasoline caused by
the major disruption of natural gas supply in Australia in 1999, which
increased demand for propane for household use and resulted in increased
propane prices.

   Operating income for this segment decreased $268,000 or 15.1% from $1.8
million in fiscal year 1998 to $1.5 million in fiscal year 1999, primarily as a
result of lower product margins. Our gross margin on subsidiary based product
sales decreased from 33.6% in fiscal year 1998 to 31.7% during fiscal year
1999. During fiscal year 1999, our gross margin on subsidiary based product
sales decreased as a result of higher material costs at the Australian and
Mexico subsidiaries due to a strengthening U.S. Dollar against those country's
foreign currencies. This decrease also was due to higher material costs at our
European subsidiary as a result of higher transfer pricing between the United
States parent and the subsidiary.

   Corporate Expenses. Corporate expenses increased approximately $520,000 or
10.4% from $5.0 million in fiscal 1998 to $5.5 million in fiscal year 1999,
primarily due to increases in administrative personnel and administrative
salaries and benefits to support our growth and international operations and
additional amortization of goodwill from acquisitions.

   Corporate Research and Development. Corporate research and development
expense increased approximately $530,000 or 21.0% from $2.5 million in fiscal
year 1998 to $3.0 million in fiscal year 1999. This increase was the result of
additional research and development efforts on the development of fuel storage
technology and other advanced technologies.

   Interest Expense. Interest expense increased $235,000 or 25.1% from $935,000
in fiscal year 1998 to $1.2 million in fiscal year 1999 as compared to the
fiscal year 1998. This increase was primarily attributable to higher borrowings
on our lines of credit as compared to the prior year and as a result of higher
long-term borrowings to fund the Algas Carburetion acquisition in December
1997, the purchase of the remaining 49.0% interest of IMPCO BV in May 1998, the
purchase of our Industrial Engine Systems business in December 1998, and the
purchase of IMPCO Japan in March 1999. The higher interest expense was
partially offset by lower interest rates on our credit facility with Bank of
America and prepayments on certain long-term borrowings from funds received
from the exercise of our common stock purchase warrants during the third
quarter of fiscal year 1998.

   Provision for Income Taxes. Our effective income tax rate was 14.7% for
fiscal year 1998 and 19.0% for fiscal year 1999. The provision for income taxes
consists primarily of federal, state and foreign taxes which are computed using
statutory rates. The effective tax rate represents the statutory income tax
rate reduced by the use of net operating loss carryforwards, research and
development tax credits and other items. During fiscal year 1999, the deferred
tax asset increased by $1.0 million or 65.3% to $2.6 million at April 30, 1999
due to research and development credits. For federal income tax purposes, we
use all net operating loss carryforwards at the end of fiscal year 1998.

   Net revenue for fiscal year 1998 increased $9.3 million or 15.0% from $61.8
million for fiscal 1997, as compared to $71.1 million in fiscal year 1998.
Contract revenues, primarily from the General Motors program, represented
approximately $5.5 million of this increase. Product sales for fiscal year
1998 increased by approximately $3.8 million or 6.5%, which was unfavorably
reduced by $2.3 million or 4.0%, as a result of a strong U.S. Dollar as
compared to foreign currencies. The following table sets forth our product
revenues by application across all business segments:

   Automotive OEM Division. Net revenues for this division increased $6.1
million or 100.3% from $6.2 million for fiscal year 1997 to $12.3 million for
fiscal 1998. This increase was the result of higher contract revenues,
primarily from the General Motors program, and higher General Motors product
revenues. Contract revenues increased $5.4 million or 161.6% from fiscal year
1998 to fiscal year 1997. This increase was primarily due to the addition of
several gaseous fuel vehicle platforms for development under the contract with
General Motors and to development contracts obtained from various federal and
state agencies.

                                      28
<PAGE>

   During fiscal year 1998, revenue attributable to equipping motor vehicles
with this division's systems increased $798,000 or 27.3% as compared to fiscal
year 1997. This revenue represented sales of 440 mid-year 1997 General Motors
pick-up trucks equipped with this division's bi-fuel natural gas fuel system
and sales of 880 dedicated liquid propane gas kits under our Teaming Agreement
with General Motors for their medium duty trucks. During fiscal year 1997, a
portion of the revenue attributable to equipping vehicles for aftermarket fleet
use in fiscal year 1997 resulted from a program with Ford Motor Company in
which this division's bi-fuel propane system was used in the 1996 model year F-
150 and F-250 pick-up trucks. The Ford program was materially completed during
the first quarter of fiscal year 1997 and is now serviced by the Gaseous Fuel
Products division.

   Operating losses for this division decreased $350,000 or 19.4% from $1.8
million in fiscal year 1997 to $1.5 million for fiscal year 1998. This decrease
was primarily the result of higher contract revenues, but nearly completely
offset by higher research and development expenses and higher general and
administrative expenses. Customer funded research and development expense
increased from $3.0 million in fiscal year 1997 to $7.4 million in fiscal year
1998. The increase in customer funded research and development was a result of
additional gaseous fuel vehicle platforms for development under the contract
with General Motors and development contracts obtained from various federal and
state agencies. This division's company funded research and development expense
decreased by $1.3 million in fiscal year 1998 or 71.9% as compared to fiscal
year 1997 as a result of efforts placed on the customer funded research and
development work.

   Gaseous Fuel Products Division. Net revenues for this division increased
$5.3 million or 12.2% from $43.0 million in fiscal year 1997 to $48.3 million
in fiscal year 1998. This increase was primarily due to higher material
handling related revenues, both domestically and internationally. The increase
in domestic and international revenues was primarily a result of the general
upswing in economic conditions, which increases the demand for forklift related
equipment. Additionally, net revenues from large industrial engines increased
to $3.3 million in fiscal year 1998 as compared to $2.6 million in fiscal year
1997. This increase was primarily a result of higher demand for large power
generation units used in power replacement and recreational applications. Also,
this division generated increased contract revenues in fiscal year 1998 under
the Varity Perkins development contract. These increases in revenues were
partially offset by decreases in revenues from the motor vehicle product and
small portable engine markets. The lower motor vehicle related revenues
resulted from lower product sales for aftermarket conversions in the United
States market due to new regulatory requirements shifting the automotive
conversion market to direct OEM installations. The reduction in small portable
engine revenues was related to new Environmental Protection Agency regulations
affecting the small engine aftermarket.

   Operating income increased $3.7 million or 33.0% from $11.1 million in
fiscal year 1997 to $14.8 million in fiscal year 1998. This increase was
primarily realized from higher gross margins as a result of higher sales
volumes and lower material costs. The increase in gross margins was partially
offset by higher research and development expenses in fiscal year 1998.
Customer funded research and development expense increased from $157,000 in
fiscal year 1997 to $263,000 in fiscal year 1998. This division's company
funded research and development expense also increased to $1.3 million in
fiscal year 1998.

   International Operations. Net revenues increased $2.3 million or 13.4% from
$17.0 million in fiscal year 1997 to $19.3 million in fiscal year 1998. During
fiscal year 1998, we realized increased revenues of $2.4 million from our
European operations, which primarily sells material handling components.
Without the strengthening U.S. Dollar, revenues from European operations would
have increased $3.9 million for fiscal year 1998. Additionally, our Mexican
operations, acquired in December 1997, added $823,000 in revenues for fiscal
year 1998. These increases in revenue were partially offset by $922,000 in
lower product sales from the Australian operation as a result of a general
economic slowdown and unfavorable price differentials between petroleum and
propane which unfavorably impacted our component sales.

   Operating income increased $506,000 or 40.0% from $1.3 million in fiscal
year 1997 to $1.8 million in fiscal year 1998, primarily as a result of our
increased sales by our European operations. The increase in operating income
for the European operations is primarily due to additional gross profit from
higher sales volumes.

                                       29
<PAGE>

   Corporate Expenses. Corporate expenses increased $681,000 or 15.8% from $4.3
million in fiscal year 1997 to $5.0 million in fiscal year 1998, primarily due
to legal expenses, incentive compensation and increases in administrative
salaries.

   Corporate Research and Development. Corporate research and development
increased $1.2 million or 92.0% from $1.3 million in fiscal year 1997 to $2.5
million in fiscal year 1998, primarily as a result of the start-up of new
projects relating to the development of next generation technologies. We
believe our future success depends on our ability to design, develop and market
new products that interface successfully with new engine electronic technology,
and which meet mandated emission standards and advanced fuel storage
technology.

   Interest Expense. Interest expense decreased by approximately $166,000 or
15.1% from $1.1 million in fiscal year 1997 to $935,000 in fiscal year 1998.
This decrease was attributable to lower borrowings on our line of credit as
compared to the prior year and prepayments on long-term borrowings primarily
from funds received from our redemption of our common stock purchase warrants.

   Provision for Income Taxes. Our effective income tax rate was 7.0% for
fiscal year 1997 and 14.7% for fiscal year 1998. The provision for income taxes
consist primarily of federal, state and foreign taxes, which are computed using
statutory rates. The effective tax rate represents the statutory income tax
rate reduced by the use of net operating loss carryforwards, research and
development tax credits and other items. During fiscal year 1997, the deferred
tax asset increased by $273,000 to $1.9 million at April 30, 1997. During
fiscal year 1998, the deferred tax asset decreased $373,000 to $1.6 million at
April 30, 1998. For federal income tax purposes, we have used all net operating
loss carryforwards as of the end of fiscal year 1998.

Liquidity and Capital Resources

   We use cash generated from our operations and bank financing to fund capital
expenditures and research and development, as well as invest in and operate our
existing operations and new businesses. While these sources of funds have been
sufficient in the past, we currently anticipate that we will require additional
sources of financing in order to capitalize on opportunities that we believe to
exist in the emerging fuel cell market. These additional sources of financing
will include the proceeds of this offering and may include bank borrowings or
public or private offerings of equity or debt securities.

   The ratio of current assets to current liabilities was 3.6:1 at January 31,
2000 and 3.1:1 at April 30, 1999. During fiscal year 2000, the total amount of
working capital increased by approximately $12.4 million to $47.7 million at
January 31, 2000. Net cash used in operating activities was $4.8 million for
the nine months ended January 31, 2000 as compared to net cash provided by
operating activities of $3.2 million for the same period in the previous year.
The increase in cash used in operating activities during the current period
resulted primarily from an increase in inventory and an increase in accounts
receivable and accrued expenses. The increase in inventory was primarily due to
inventory build in anticipation of the relocation of a portion of our
Automotive OEM division's manufacturing operations from Irvine, California to
Guaymas, Mexico and increased sales volume across all of our operating
segments. The increase in accounts receivable is primarily due to the increased
billings associated with higher sales levels. At January 31, 2000, accounts
receivable as a percent of net revenue was comparable to the same period in
prior fiscal year.

   Net cash used in investing activities for the nine months ended January 31,
2000 was approximately $2.4 million, a decrease of approximately $3.4 million
from the same period in the previous year. This decrease is primarily a result
of the previous year's third quarter acquisition of the Industrial Engine
Systems business for approximately $3.9 million and the previous year's first
quarter purchase of the remaining 49.0% interest in IMPCO BV, which resulted in
a net use of cash of approximately $692,000.

   Net cash provided by financing activities for the nine months ended January
31, 2000 was approximately $8.9 million. For the nine months ended January 31,
2000, we increased our borrowing under the operating lines of credit by
approximately $10.4 million, primarily for working capital. During the same
period, we paid approximately $1.9 million on our term loans.


                                       30
<PAGE>

   We have a $20.0 million revolving line of credit, $3.0 million revolving
line of credit for IMPCO Mexicano, $6.0 million non-revolving line of credit
for future acquisitions, and $3.0 million non-revolving line of credit for
future capital expenditures with Bank of America. At January 31, 1999,
approximately $13.0 million, $643,000 and $1.7 million were outstanding under
the revolving line of credit, the revolving line of credit for IMPCO Mexicano
and the capital expenditures facility, respectively. Our revolving lines of
credit expire on August 31, 2001. While our acquisition facility and the
capital lease facility expire on August 31, 2000, we have the option to convert
each of them into a term loan payable in five years. In addition, our
subsidiary in the Netherlands has a fl. 3,000,000 (US $1.4 million at February
1996) credit facility with Mees Pierson, a financial institution in the
Netherlands. At January 31, 2000, there was no outstanding balance under this
credit facility. Our subsidiary in Japan has a (Yen)60,000,000 (US $559,000 at
March 1999) revolving term loan facility with the Hong Kong and Shanghai
Banking Corporation Ltd., Osaka Branch. At January 31, 2000, there was an
outstanding loan balance of (Yen)50,000,000 (US $466,000) on this term loan.

Derivative Financial Instruments

   We use 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.

   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 January 31, 2000, we had currency
forward contracts protecting US $382,000 in inventory purchases. At January 31,
2000, the fair value of foreign currency forward contracts was approximately US
$14,000. 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.

   Interest Rate Management. We use interest rate swap agreements with Bank of
America to manage our exposure to interest rate changes and to stabilize the
cost of borrowed funds. When this type of agreement is executed, the swap is
linked to a specific debt instrument. At January 31, 2000, we had approximately
$4.1 million outstanding under fixed interest rate agreements at a weighted-
average fixed interest rate of 7.94%. Absent these fixed rate agreements, the
weighted-average variable rate for this debt at January 31, 2000 would have
been 7.85%. At January 31, 2000, the fair value of interest rate swap
agreements approximated carrying value.

   Debt Obligations. The following table summarizes our debt obligations at
April 30, 1999. The interest rates represent weighted average rates, with the
period end rate used for the variable rate debt obligations. The fair value of
the debt obligations approximated the recorded value as of April 30, 1999.

Recent Accounting Pronouncements

   The Financial Accounting Standards Board has issued SFAS 133 "Accounting for
Derivative Instruments and for Hedging Activities," which is effective for
fiscal years beginning after June 15, 1999. SFAS 133 requires derivatives to be
recorded on the balance sheet at fair value and establishes special accounting
for the following three types of hedges: hedges of changes in the fair value of
assets, liabilities or firm commitments, referred to as fair value hedges,
hedges of the variable cash flows of forecasted transactions such as cash flow
hedges and hedges of foreign currency exposures of net investments in foreign
operations. The accounting treatment and criteria for each of the three types
of hedges is unique. Changes in fair value of derivatives that do not meet the
criteria of one of these three categories of hedges would be included in
income. SFAS 133 was amended by SFAS 137, which delayed its effective date. We
will determine what impact, if any, it will have on our financial position,
results of operations, and cash flows. Currently, we do not anticipate adopting
this standard before May 1, 2001.

   The Financial Accounting Standards Board has recently 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 by prescribed Accounting Principle
Board No. 25. The new rules are applied prospectively to all new awards,
modifications to outstanding awards and changes in grantee status after July 1,
2000, with certain exceptions. We are considering the effects these changes
make and will implement any changes to our plans as deemed appropriate.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements," or
SAB 101. SAB 101 summarizes certain of the SEC Staff's views in applying
generally accepted accounting principles to revenue recognition in financial
statements. We are currently evaluating the impact of SAB 101. We do not
believe that our evaluation will result in any material change to our revenue
recognition policies.

                                    BUSINESS

Overview

   We are a leading designer, manufacturer and supplier of advanced fuel
delivery and storage technology systems and components that allow internal
combustion engines and fuel cell systems to operate in a variety of
transportation, material handling, and industrial and power generation
applications using clean fuels such as hydrogen, propane, natural gas and
methanol. We have designed these systems to maximize efficiency and performance
by electronically sensing and regulating the proper proportion of fuel and air
used by internal combustion engines and fuel cells. Based on over 40 years of
technology development and expertise in producing cost-effective, safe and
durable fuel technology systems for engines, we believe that we will be
positioned to provide enabling products and technologies in the rapidly
emerging fuel cell industry.

   Current internal combustion engines have contributed to a worldwide
pollution problem. As a result, a number of automotive, industrial and power
generation manufacturers are developing alternative clean propulsion systems
such as fuel cells. We offer fuel delivery, fuel storage and electronic control
systems to those manufacturers to facilitate the development of these
propulsion systems. Many OEMs are also adapting their internal combustion
engines to use cleaner burning alternative fuels to reduce their harmful
emissions. We offer both conversion products and systems to these OEMs and for
aftermarket conversions.

   Since 1986, we have produced more than 2.5 million gaseous fuel systems and
components. We sell these systems and components directly to the user and
through more than 400 distributors and dealers worldwide and through our OEM
customers.

   We entered into a Teaming Agreement with General Motors in 1997. Under this
agreement, we have specifically designed fuel conversion products as a cost-
effective solution to address General Motors' demand for alternative fuel
vehicles. We are also developing and adapting our technologies for fuel cell
powered zero emission vehicles for General Motors and other OEMs.

   Also in 1997, we opened our Advanced Technology Center in Irvine,
California, a research and development facility with more than 140 scientists,
engineers, professionals, and support staff. The Advanced Technology Center
focuses entirely on the development of clean emission advanced fuel delivery,
storage and electronic control systems, particularly those related to emerging
fuel cell technologies. Since 1994, we have invested more than $49 million on
research and development of gaseous fuel enabling technology for use in fuel
cells and engines. As a result, we believe that we have gained technological
leadership in these enabling products which we have designed to convert
internal combustion engines to alternative cleaner fuels and to fully
participate in the fuel cell market with new state-of-the-art fuel and cost-
effective fuel delivery and fuel storage products.

Alternative Fuel Industry

   Alternative fuel technology markets were developed from, and continue to be
propelled by, three independent drivers: economics, environmental concerns and
energy independence. We believe the price differential between propane or
natural gas and gasoline drives the economics of the alternative fuels market.
The price of traditional liquid fuels such as gasoline is typically twice that
of natural gas or propane. By converting an internal combustion engine to run
on propane or natural gas, through the installation of our products, customers
can capitalize on the price differential. Customers are typically able to
recoup the cost of the conversion in six to eighteen months, depending on the
fuel spread. Transportation companies such as taxi companies, transit and
shuttle bus companies, United States government fleets and parcel delivery
companies such as the United States Postal Service and United Parcel Service
are well positioned to take advantage of these economics. We sell our systems
to forklift users who often operate equipment indoors where toxic emissions are
of a concern. Small and large industrial engine users are also often motivated
to capitalize on cost benefits. In all these situations, it is relatively easy
to establish centralized fueling stations. Because the price differential
between these gaseous fuels and gasoline in the United States is less than that
in many foreign countries, the United States market is often more impacted by
environmental concerns.

                                       33
<PAGE>

   The negative environmental impact associated with liquid 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. Most major international cities are experiencing significant
pollution arising from gasoline and diesel emissions. These cities also have
the largest concentrations of fleet operators and many are taking steps to
reduce emissions by typically converting vehicles from liquid fuel to natural
gas and propane. For example, in Mexico City, one of the largest cities in the
world, the government has taken steps such as alternating the days in which
vehicles with even and odd numbered license plates can be used. However,
vehicles running on propane or natural gas can be operated every day, creating
a significant advantage for corporate and industrial users, such as major
distributors of products within the city limits.

   In the United States, such legislative acts as the Comprehensive National
Energy Strategy, the Clean Air Act Amendments of 1990 and the Energy Policy Act
of 1992 in the aggregate provide goals for energy and efficiency and strict
emission standards and promote the development and implementation of
alternative fuels and related technologies. Several states, including
California, Massachusetts, New York and Vermont have also adopted legislation
targeted at reducing harmful vehicle emissions. In addition, over 25 countries
worldwide have enacted air pollution regulations or programs favoring the use
of alternative fuels, including China, India, Mexico and the European Common
Market.

   In addition to economics and environmental concerns, energy independence is
a significant driver for the alternative fuel market. Many countries have
significant natural gas reserves and are seeking to use alternative fuels to
reduce their dependence on imported oil. Natural gas is consumed domestically
since it is difficult to transport internationally in a gaseous state and
liquefying natural gas tends to be costly. By converting their domestic
transportation market to natural gas or propane, which is a derivative of
natural gas, countries are able to lessen their demand for gasoline which is
derived from oil.

Fuel Cell Industry

   The newly emerging fuel cell industry represents an advancement in fuel
technologies to address the worldwide environmental concerns and long term
security of supply for inexpensive liquid fuels reserves. A fuel cell, by
nature of its operating principles, is efficient and extracts more energy from
a fuel than combustion based technologies. Fuel cells have emerged as a leading
power source for advanced fuel systems that propel motor vehicles and
industrial engines due primarily to the fundamental characteristics of the
electrochemical process: low emissions, reduced noise and high efficiency. The
fuel cell market is anticipated to be a large market characterized by high
levels of growth. Fuel cell manufacturers are targeting the transportation,
stationary and portable markets. While we believe that our gaseous fuel storage
system will eventually be applicable to all three of these markets, we
anticipate initially focussing on the transportation market where we believe we
will be able to leverage off of our other alternative fuel technologies and our
relationships with automotive OEMs such as General Motors.

   A fuel cell is an electrochemical device that produces electricity silently
and without combustion. Hydrogen fuel, which can be obtained from hydrocarbons
such as methanol, natural gas or petroleum is then combined with oxygen from
the air in a fuel cell to produce electricity, with useable heat and water as
the only by-products. This process is the reverse of electrolysis by which
water can be split into hydrogen and oxygen by passing an electric current
through water. A key to optimizing the performance of a fuel cell is the proper
metering and delivery of its hydrogen fuel and air to its fuel stacks and the
efficient storage of its fuel to maximize its time of usage. These fuel systems
must be cost-effective, light weight and safe.

   To generate usable electric power, a complete fuel cell power system, like a
complete automobile engine or power generator, requires a fuel supply and fuel
metering system. If hydrogen is not the initial fuel for this system, hydrogen
can be obtained from hydrocarbon fuels such as methanol, natural gas or
petroleum using a device called a reformer. A reformer breaks down hydrocarbon
fuels using heat and a catalytic process. Each hydrocarbon based fuel faces
challenges to become a practical fuel for fuel cell powered vehicles. While

                                       34
<PAGE>

methanol is the easiest fuel to reform and requires less complex systems, it is
not widely available in the current fuel distribution infrastructure and is
corrosive. Natural gas can also be reformed, yet it is not widely available in
the current fuel distribution infrastructure. Gasoline is widely available, and
easy to store, but it is difficult to reform and requires very complex systems
that reduce efficiencies and increase the pollutants produced by the fuel
processor. Our technology and products can function in connection with any of
these hydrogen fuel sources. Regardless of the fuel used, we believe that the
fuel cell system will require on board storage, fuel metering and electronic
controls.

Alternative Fuel and Fuel Cell Markets

   The markets for transportation, material handling, industrial engine
conversions and fuel cell applications are large and are growing rapidly.
According to Freedonia Group, an independent market research firm, global OEM
alternative vehicle sales are expected to grow to 170,000 units annually by the
year 2002 from 31,900 units in 1997. Propelled by the commercialization of fuel
cell vehicles between the years 2003 and 2005, the National Fuel Cell Research
Center based at the University of California, Irvine, projects that the annual
revenues of the fuel cell industry will exceed $10 billion by 2010.

   According to the Industrial Truck Association and the Material Handling
Institute of America, the world wide material handling new lift-truck market
was approximately 430,000 units in 1998 and the number of lift trucks in
service was at least 1.6 million by the end of 1999. We expect that additions
of new lift trucks to the market will continue at or above the current historic
annual rate of 4% to 5% for at least five years. Currently, the Industrial
Truck Association estimates that approximately 15% of all lift-trucks are using
alternative fuels, mostly in indoor applications such as warehousing and food
processing, where indoor air quality is required. California has announced it
will enforce emission regulations applying to forklifts in 2001. The
Environmental Protection Agency will also implement emission regulations
applying to forklifts in 2004.

   Ford, DaimlerChrysler, General Motors, Honda, Mazda and Nissan have each
announced their intention to commercialize fuel cells in motor vehicle
applications sometime between the years 2003 and 2005. We intend to participate
in the growth of the fuel cell segment of this industry by focussing primarily
on the fuel cell integration delivery, storage and components in fuel cell and
gaseous fuel applications. However, we have no current plans to manufacture
fuel cells or reformers.

Competitive Advantage

   We believe our current and future technological leadership position in the
alternative fuel and fuel cell industries will result from our continued
success in the design, manufacturing and commercialization of advanced fuel
delivery systems and components, our relationships with leading companies in
our targeted transportation, material handling and industrial and power
generation markets, and our substantial financial commitment to research and
development and proven ability to develop and commercialize products in the
emerging fuel cell and alternative fuel industries. We believe our competitive
strengths include:

   Industry Leader. We are a leader in the rapidly emerging alternative fuel
industry and a market share leader in the use of non-liquid fuels in internal
combustion engines. Our technology leadership position is derived from the
broad application and integration of our technology and enabling systems into
the expanding advanced fuel technology industry. Our significant investment of
more than $49 million in research and development over the past six years,
coupled with our history and experience in this industry has provided us with a
strong technology base for new product innovation. Our new proprietary fuel
cell enabling technologies are currently patented or patent pending, which
could make it more difficult for new entrants in the industry to develop
directly competing products based on the same or similar technologies.

                                       35
<PAGE>

   Advanced Enabling Technologies and Systems for Fuel Cells. Our research in
fuel storage, fuel delivery and electronic system controls have delivered
advanced, low cost technologies, which we believe can be adapted to apply to a
broad range of fuel alternatives. We have also concentrated efforts on
extensive testing and validation of our new advanced fuel technologies which
focus upon safety and durability. In 1995, we began development of products for
fuel cell applications in our target markets. Our new TriShield(TM) all-
composite, light weight and low cost fuel storage tank is of special interest
to the fuel cell industry due to its ability to store hydrogen at high
pressures and at a very attractive weight-to-strength ratio. This tank, in
conjunction with our patented in-tank regulator, is particularly cost-effective
when compared to existing and other traditional tank and regulator
technologies. Sandia National Laboratories is currently evaluating our tanks
for potential hydrogen storage applications. Our new fuel metering disc
injector has also been well received among automotive and fuel cell
manufacturers. Our patent pending technology associated with the injector uses
low leakage and low friction discs to meter the fuel rather than the
conventional plunger technology now used. We believe our new injector, which
utilizes high volume gasoline injector parts, will have broad applications in
fuel cell and alternative fuel systems, with potential in the traditional
liquid fuel market.

   Proven Manufacturing Methods. We have over four decades of experience in the
manufacture and development 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
United States, Australian and European facilities have achieved or are in the
process of implementing ISO-9000 or QS-9000 certification. We believe our
manufacturing expertise will enable us to successfully address the fuel cell
industry.

   Strong OEM Relationships. We have a Teaming Agreement with General Motors to
supply alternative fuel systems and components for General Motor's vehicles. We
are currently their exclusive provider of natural gas and propane systems and
cooperate with them in sharing non-proprietary technology, test facilities and
procurement resources. We also sell conversion components to General Motors in
international markets. During the fiscal years ended April 30, 1998 and 1999,
sales to General Motors amounted to 17.3% and 27.8% of our revenues,
respectively. In addition, we have longstanding relationships with many
domestic and international OEMs, including BMW, Caterpillar, Clark, Cummins,
Daewoo, Detroit Diesel, Deutz, Ford Australia, Hyster/Yale/Sumitomo, Isuzu,
Komatsu, Linde, MANN, Mazda, Mitsubishi, Nissan, ONAN, Perkins, Scania, Toyota
and Volvo.

   In-Depth System Integration Expertise. As more OEMs seek to reduce costs by
outsourcing key tasks and reducing numbers of suppliers, we have increasingly
focused on capturing additional revenue opportunities by expanding our current
systems integration capabilities. In 1996, we created our Automotive OEM
division to serve this customer value-added opportunity. In 1998, through the
Crusader acquisition, we established our Industrial Engine Systems business in
Sterling Heights, Michigan, which provides systems integration of our low-
emission products onto 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
emerging fuel cell markets.

   Positioned for Global Growth. With eight international facilities and over
300 distributors and dealers outside the United States, we believe that we are
uniquely positioned to capitalize on regional growth opportunities. We believe
that the alternative fuel markets will grow dramatically internationally,
particularly in China, India, Japan, Mexico and Southeast Asia where urban
pollution problems will continue to predominate. We are currently working with
the governments of Mexico and China to develop advanced fuel solutions for
public transportation, government and taxi fleets. Recently, the government of
China selected us and General Motors to undertake a marketing and feasibility
study related to the use of advanced fuels vehicles in China. These vehicles
have been provided to China for evaluation. In Mexico, the government of Mexico
State recently selected us as the preferred vendor for the conversion of over
6,000 taxi and mass transit vehicles, which could reach 70,000 vehicles in the
next five years.

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, fuel storage and electronic
control systems for the alternative fuel and fuel cell industries. We believe
that this position results from our current technology advantage and our
investment in research and development in this rapidly emerging industry. Our
investment has and will continue to permit us to develop and supply new
technology and products to our target markets which are transitioning to
gaseous fueled internal combustion engines. We intend to expand the technology
gap between ourselves and our competitors to capture the leading position in
new fuel cell opportunities.

   Focus on Fuel Cell Enabling Technologies and Products. Since 1995, we have
invested significantly in research and development of technology and products
that support the use of fuel cell systems. The commercialization of our
technology products has established us as a leader in fuel metering, fuel
storage and electronic controls for fuel cell systems. We plan to continue to
expand our research and product development in fuel metering, fuel delivery and
electronic control systems for fuel cell systems. We plan to develop and expand
sales of fuel cell related products by focusing business development efforts
initially on the transportation industry, and secondarily on the industrial
power generation and material handling markets. We will seek to establish joint
development programs and strategic alliances with the major fuel cell
developers and automobile industry leaders.

   Develop and Expand Key Industry Relationships. We believe that OEMs will
drive industry growth. Building on our Teaming Agreement with General Motors,
we plan to develop additional relationships with major OEMs. We also plan to
work with other manufacturers in the fuel cell industry and are currently in
discussions with Delphi, Ballard Power Systems, Inc. and Xcellsis, formerly dbb
Fuel Cell Engines, GmbH, a German company jointly owned by DaimlerChrysler,
Ford and Ballard.

   Leverage Technology to Capture Future Fuel Cell Markets. Our technology and
product leadership in the alternative fuels industry in gaseous fuel systems,
fuel storage and electronic control is complementary to the fuel and fuel
storage technology required for fuel cells. We believe our core technologies
have and will continue to be adapted to develop products for the fuel cell
industry.

   Expand and Broaden Systems Integration Expertise. We are increasing our
existing capabilities to provide the integration, testing, validation and
manufacturing of our products and systems into the transportation, material
handling and industrial and power generation engine markets. As more OEMs seek
to reduce costs and shorten time to market by outsourcing key tasks and
reducing numbers of suppliers, we are increasingly focused on capturing
additional revenue opportunities by expanding into value-added services such as
systems integration. For example, in 1998, we established an industrial systems
unit in Michigan to provide systems integration for our products onto engines
subsequently to be sold to industrial OEMs which are then ready for
installation into end products. Our Automotive OEM division has integrated our
products into over 6,800 vehicles for General Motors since 1997.

   Expand Bases of Operations in High Growth Global Regions. We believe that
significant growth opportunities for our current and future businesses exist
outside the United States and targeted high growth markets such as Latin
America, Asia and Europe through acquisitions and joint ventures, strengthening
of our distributor network and developing key local business and governmental
support and recognition. In particular, we are developing close relationships
with the governments of Mexico and China. We believe that working with local
governments is essential to expanding into international markets and that our
discussions with government officials have helped us to develop regulations in
Mexico and China.


                                       37

Customers and Strategic Relationships

   We market our products and services to OEMs, distributors, sub-distributors
and dealers through an international network of over 400 distributors and
dealers into over 30 countries. Our customers include some of the world's
largest OEMs and engine manufacturers, including BMW, Caterpillar, Clark,
Cummins, Daewoo, Detroit Diesel, Deutz, Ford Australia, Hyster/Yale/Sumitomo,
Isuzu, Komatsu, Linde, MANN, Mazda, Mitsubishi, Nissan, ONAN, Perkins, Scania,
Toyota and Volvo. We are working with a number of these customers to resolve
their fuel metering, fuel storage and electronic control requirements as they
integrate fuel cells into their business strategies.

   We entered into a Teaming Agreement with General Motors in 1997, which
encompasses the design, development, manufacture and vehicle integration of our
natural gas and propane fuel systems into their vehicles. In connection with
this relationship, we provide complete fuel system integration services and
validation, including crash, hot and cold weather and high altitude, emission
certification, service plans and procedures and manufacturing. We intend to
establish similar relationships with other leading OEMs. Our Teaming Agreement
with General Motors includes sharing of non-proprietary technology,
corroboration of technical staffs to leverage areas of technical expertise for
mutual benefit, sharing of laboratory and testing facilities, and use of
General Motors procurement network. General Motors has agreed to purchase
gaseous fuel propulsion systems or related components developed under this
agreement from us if:

  . General Motors does not produce the components;

  . we can supply such components; and

  . we are competitive in terms of price, quality and service.

   The Teaming Agreement also provides for a mutual right of first refusal if
we jointly develop new products under this agreement. As part of this right of
first refusal, we may not solicit sales to any third parties of any gaseous
fuel propulsion system or related components developed under the Teaming
Agreement for a period of two years from the date of General Motors' commercial
introduction. To date, the Teaming Agreement has been applied exclusively to
the installation of gaseous fuel systems and does not cover any joint
development efforts other than those that had been specific to General Motors
application requirements.

Products and Services

   Many of our products are based on proprietary and patented technology
focused on fuel storage, fuel flow and fuel management and engine control
management for fuel cell applications and internal combustion engines. We have
designed our products to enable fuel cell and internal combustion propulsion

   Assembly and System Installation. The Automotive OEM division's
manufacturing activities currently consist solely of assembly and system
installation. We assemble the majority of our components at our facility in
Guaymas, Mexico, but outsource the assembly of complex electronic components
and select key suppliers for certain components of developed fuel systems.
Approximately ten suppliers accounted for approximately 50% of raw material
purchases. A major supplier of components on certain programs is our Gaseous
Fuel Products division. Complete systems are installed on vehicles at the OEM
manufacturing facility or at third party equipping sites. The criteria for the
establishment of a site is proximity to vehicle manufacturing and delivery
points.

   The Automotive OEM division follows quality processes in accordance with QS-
9000 and is QS-9000 certified. The Automotive OEM division has not experienced
and does not expect to experience any significant difficulty in complying with
environmental regulations applicable to its assembly processes and facilities.
The Automotive OEM division work force at the Irvine and Guaymas facilities are
non-union.

Gaseous Fuel Product Division

   The Gaseous Fuel Product division is a leading supplier of engine components
and systems that allow internal combustion engines to operate on clean burning
gaseous fuels, primarily propane and natural gas. The Gaseous Fuel Product
division designs, develops, manufacturers and markets components and systems

   Manufacturing. We manufacture or assemble all of our Gaseous Fuel Product
division products at our headquarter facilities in Cerritos, California and in
Sterling Heights, Michigan. Current manufacturing operations consist largely of
mechanical assembly with light machining. We rely on outside suppliers for
parts and components and obtain components for products from a variety of
domestic automotive and electronic part suppliers, local diecasters, stamping
operations and machine shops. For the fiscal year ended April 30, 1999, ten
suppliers accounted for approximately 74% of the Gaseous Fuel Product
division's raw material purchases.

   Material costs, die cast aluminum parts in particular, represent the major
component 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. The Gaseous Fuel Product division follows quality processes in
accordance with ISO 9001 and expects to be ISO 9001 certified by the end of
fiscal year 2000. We have not experienced and do not expect to experience any
significant difficulty in complying with environmental regulations applicable

division work force at Cerritos and Sterling Heights is non union.

   Distribution. During the fiscal year ended April 30, 1999, sales to
distributors accounted for approximately 67.4% and sales to OEM customers
accounted for approximately 33.6% of sales. This is consistent with fiscal
years ended April 30, 1998 and 1997. Distributors primarily service the
aftermarket conversion business and small volume OEMs, and are generally
specialized and privately owned enterprises. Many domestic distributors have
been our customers for more than 30 years, and most of our export distributors
have been customers for more than 20 years. OEM customers for vehicle and
forklift manufacturers include Clark Material Handling Co., Ford Motor Company,
Generac, Kohler Company, Mitsubishi Caterpillar Forklift America, Inc., NACCO
Material Handling Group, Onan Corporation and Toyota Industrial Equipment Mfg.
Inc. OEM customers for heavy duty industrial equipment manufacturers include
Caterpillar, Inc., Cummins Engine Company and Waukesha Engine.

Japan

   IMPCO Technologies Japan, our wholly-owned subsidiary, was founded in March
1999 and is headquartered in Fukuoka, Japan. This subsidiary provides marketing
and customer support for Japanese OEMs and distributors. We strengthened IMPCO
Japan's ability to deliver this support through the acquisition of our Mikuni
distributor in 1999. Mikuni has distributed IMPCO products in Japan since 1994.
IMPCO Japan is closely involved in the development of the Japanese industrial
and motor vehicle alternative fuels market with a focus on lift truck engine
manufacturing OEMs, automotive OEMs, mass-transit and truck applications. Japan
has recently established emissions regulations and an alternative fuel mandate
that we anticipate will promote the use of alternative fuels in motor vehicles
over the next five years. Two major OEMs, Toyota and Honda, have introduced
1999 alternative fuel vehicles for sale. Japanese automotive OEMs are also
involved in the development of fuel cell vehicles.

   Strategy. IMPCO Japan's strategy is to support the emerging motor vehicle
alternative fuels and fuel cell markets throughout Japan, Asia, China and the
Pacific Rim regions with component and application development, systems and
engineering services to OEMs, global customer support, a global distribution
network and emissions and testing support. In particular, we seek to increase
its presence in the lift trucks, industrial engines and OEM market segments,
including particularly the automotive aftermarket.

Mexico

   Grupo IMPCO Mexicano, our majority owned subsidiary, provides technical and
customer support for the conversion of fleets and dealers in the rapidly
growing Mexican market for conversion to alternative fuels. As a result of the
Algas acquisition in 1998, IMPCO Mexicano links us to a growing marketplace for
our products. In Mexico, alternative fuels cost approximately 50% of the price
of gasoline, and there is a desire to implement effective clean air solutions,
while preserving natural resource independence. This has resulted in a strong
and growing market for alternative fuel vehicles. Under current government
mandates, 200,000 public and private mass transit vehicles must be converted to
clean burning propane, with a potential market value of over $900 million.

                                       45
<PAGE>

   Strategy. IMPCO Mexicano is part of our strategy to strengthen our global
customer support in Mexico, Central and South America. IMPCO Mexicano is
uniquely positioned to grow within the Latin American market by drawing upon
the expertise of our other divisions, while implementing specific regional
activities. IMPCO Mexicano plans to focus on market, application and sales
development for the conversion of private and public fleets to alternative
fuels. Development of key business and governmental support is of primary
importance.

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, van or engine sold in the United States 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. We have also obtained international
emissions compliance certification in Argentina, Australia, Brazil, Canada,
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, Inc. and the
American Gas Association. While approval is not always required or offered by
these agencies, we believe full compliance and approvals enhance the
acceptability of products in the domestic marketplace. Many foreign countries
also accept these agency approvals as satisfying their "approval for sale"
requirements in their markets.

Competition

   We are a leading provider of fuel storage, fuel metering and electronic
control systems for the alternative fuel and fuel cell markets. While we
estimate that there are over 20 OEMs of gaseous fuel delivery systems
worldwide, we believe we have no single global competitor present in any of the
regions and markets where we are active. We believe we are the only company
which provides products and integrated services for all gaseous alternative
fuels, in all global markets for use in all end use applications.

   Our key competitors in the gaseous fuel delivery systems, accessory
components and engine conversions markets include Asian, GFI, Koltec, Landi,
Lovato, OMVL, Tartarini and Vialle, which together with us account for a
majority of the world market for alternative fuel products and services. Some
motor vehicle OEMs such as Ford, Honda, Toyota and Volvo have developed their
own systems which currently use our components or could in the future. In
addition, various motor vehicle OEMs, including Ford, Honda, Mazda, Nissan,
Toyota and Volvo have developed fuel systems for their own vehicles, some of
which use our components.

   In fuel cell technology, our area of expertise is in fuel storage, fuel and
gas metering and the electronic control of fuel, including air to the fuel cell
or the fuel reformer. Our principal competition in the alternative fuel and
fuel cell markets consists of very small independent companies or universities
supported by government grants. In the fuel cell industry, we do not compete
with fuel cell manufacturers, such as Ballard Power Systems Inc., General
Electric, Plug Power Inc. or United Technologies, whose technical focus is on
fuel cell and fuel reformer technology. Instead, we provide ancillary systems
and enabling technologies that complement the fuel cell stack.

Intellectual Property

   We currently rely primarily on patent and trade secret laws to protect our
intellectual property. We currently have over 14 United States patents issued
and over 16 foreign patents issued. The United States patents expire between
October 2004 and March 2017. The foreign patents expire between November 2001
and October 2018. We also currently have one United States patent application
and one foreign patent application. Our pending patent applications may not be
allowed. Even if they are allowed, these patents may not provide us a
competitive advantage. Competitors may successfully challenge the validity and
scope of our patents and trademarks.

                                       46
<PAGE>

   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 do not believe our intellectual property
provides significant protection from competition. We believe that patent,
copyright, trademark and trade secret protection are less significant 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.

   IMPCO, BEAM and GARRETSON are our United States registered trademarks. These
marks are also registered in other countries throughout the world.

Year 2000

   Over the past several years, we have recognized the need to ensure that our
operations would not be adversely impacted by Year 2000 software failures. We
took various initiatives intended to ensure that our computer equipment and
software would function properly with respect to dates in the Year 2000 and
thereafter. We completed an assessment of the Year 2000 issue through
communication with our key customers, suppliers, financial institutions and
others with which we conduct business and a review of our current internal
computer systems to identify potential Year 2000 issues. Additionally, we
developed and implemented plans when required to address system modifications.
We also established a contingency plan to address Year 2000 risk factors
outside of our control. As of the date of this filing, we have not experienced
any material Year 2000 problems with our internal systems or products, nor have
we experienced any material problems with any of our key customers or
suppliers. We believe that the financial impact of updating our systems to
address the Year 2000 issue was not material to our consolidated financial
position, results of operations or cash flows.

Backlog

   As of January 31, 2000, our backlog for our products was approximately $19.5
million. We measure backlog for our product sales from the time orders become
irrevocable, which generally occurs 90 days prior to the date of delivery.

Employees

   As of March 31, 2000, we employed approximately 581 persons, including, in
the United States, approximately 104 in research and development, 285 in
manufacturing and assembly, 40 in sales and marketing, 47 in management and
finance and 109 internationally. We consider our relations with our employees
to be good.

                                       47

   We also lease nominal amounts of office space in Japan, Germany, France, the

   We believe our facilities are presently adequate for our current core
product manufacturing operations and OEM development programs and production.
We anticipate that we will require additional space as we expand into the
emerging fuel cell enabling technologies market, and believe that we will be
able to obtain suitable space as needed on commercially reasonable terms.

Legal Proceedings

   We are a party to several legal actions, but we do not believe that any of
these actions will have a material adverse effect on our business, financial
condition or results of operations.

    Plan. We matched 50% of each participant's annual deferred compensation
    contribution under the Deferred Compensation Plan and approximately 50% of
    our matching contribution is in the form of options under the Incentive
    Stock Option Plans. Options are granted at the fair market value of our
    Common Stock on the date of grant and vest cumulatively at the rate of 40%
    after the first two years following the date of the grant and 20% each year
    thereafter so that the employee is 100% vested after five years. However,
    if employment terminates due to death or disability, retirement at or after
    age 62, or termination without cause, then options vest at the rate of 25%
    for each full calendar year of employment. Options may be exercised only
    while an optionee is employed by us, or within three months following
    termination of employment. If termination results from death or disability,
    options may be exercised within one year of the termination date. In no
    event may options be exercised more than ten years after date of grant.

   The representatives have advised us that the underwriters propose to offer
the shares of common stock to the public at the public offering price set forth
on the cover page of this prospectus and to certain dealers at that price less
a concession of not in excess of $   per share, of which $   may be reallowed
to other dealers. After this offering, the public offering price, concession
and reallowance to dealers may be reduced by the representatives. No such
reduction shall change the amount of proceeds to be received by us as set forth
on the cover page of this prospectus. The common stock is offered by the
underwriters as stated herein, subject to receipt and acceptance by them and
subject to their right to reject any order in whole or in part.

   The underwriters have advised us that they do not expect sales to
discretionary accounts to exceed five percent of the total number of shares
offered.

 Over-Allotment Option

   We have granted to the underwriters an option, exercisable during the 30-day
period after the date of this prospectus, to purchase up to 375,000 additional
shares of common stock to cover over-allotments, if any, at the public offering
price less the underwriting discount set forth on the cover page of this
prospectus. If the underwriters exercise their over-allotment option to
purchase any of the additional 375,000 shares of common stock, the underwriters
have severally agreed, subject to certain conditions, to purchase approximately
the same percentage thereof as the number of shares to be purchased by each of
them bears to the total number of shares of common stock offered in this
offering. If purchased, these additional shares will be sold by the
underwriters on the same terms as those on which the shares offered hereby are
being sold. We will be obligated, pursuant to the over-allotment option, to
sell shares to the underwriters to the extent the over-allotment option is
exercised. The underwriters may exercise the over-allotment option only to
cover over-allotments made in connection with the sale of the shares of common
stock offered in this offering.

 Indemnity

   The underwriting agreement contains covenants of indemnity among the
underwriters, us and the selling stockholders against certain civil
liabilities, including liabilities under the Securities Act, and liabilities
arising from breaches of representations and warranties contained in the
underwriting agreement.

 Lock-Up Agreements

   Each of our executive officers and directors and certain of our other
stockholders have agreed, subject to specified exceptions, not to offer to
sell, contract to sell, or otherwise sell, dispose of, loan, pledge or grant
any rights with respect to any shares of common stock or any options or
warrants to purchase any shares of common stock, or any securities convertible
into or exchangeable for shares of common stock owned as of the date of this
prospectus or thereafter acquired directly by those holders or with respect to
which they have the power of disposition, without the prior written consent of
FleetBoston Robertson Stephens Inc. This restriction terminates 135 days after
the effective date of this prospectus. However, FleetBoston Robertson Stephens
Inc. may, in its sole discretion and at any time or from time to time before
the termination of the 135-day period, without notice, release all or any
portion of the securities subject to lock-up agreements. There are no existing
agreements between the representatives and any of our stockholders who have
executed a lock-up agreement providing consent to the sale of shares prior to
the expiration of the lock-up period.

   In addition, we have agreed that during the lock-up period we will not,
without the prior written consent of FleetBoston Robertson Stephens Inc.,
subject to certain exceptions, consent to the disposition of any shares held by
stockholders subject to lock-up agreements prior to the expiration of the lock-
up period, or issue, sell, contract to sell, or otherwise dispose of, any
shares of common stock, any options or warrants to purchase any shares of
common stock or any securities convertible into, exercisable for or
exchangeable for shares of common stock other than our sale of shares in this
offering, the issuance of our common stock upon the exercise of outstanding
options or warrants, and the issuance of options under existing stock option
and incentive plans provided that those options do not vest prior to the
expiration of the lock-up period.

 Listing

   The common stock is traded on the Nasdaq National Market under the symbol
"IMCO."

 Stabilization

   The representatives have advised us that, pursuant to Regulation M under the
Securities Act of 1933, some persons participating in the offering may engage
in transactions, including stabilizing bids, syndicate covering

                                       57
<PAGE>

transactions or the imposition of penalty bids, that may have the effect of
stabilizing or maintaining the market price of the shares of common stock at a
level above that which might otherwise prevail in the open market. A
"stabilizing bid" is a bid for or the purchase of shares of common stock on
behalf of the underwriters for the purpose of fixing or maintaining the price
of the common stock. A "syndicate covering transaction" is the bid for or
purchase of common stock on behalf of the underwriters to reduce a short
position incurred by the underwriters in connection with the offering. A
"penalty bid" is an arrangement permitting the representatives to reclaim the
selling concession otherwise accruing to an underwriter or syndicate member in
connection with the offering if the common stock originally sold by such
underwriter or syndicate member purchased by the representatives in a syndicate
covering transaction and has therefore not been effectively placed by such
underwriter or syndicate member. The representatives have advised us that such
transactions may be effected on the Nasdaq National Market or otherwise and, if
commenced, may be discontinued at any time.

 Passive Market Making

   In connection with this offering and before the commencement of offers or
sales of the common stock, certain underwriters who are qualified market makers
on the Nasdaq National Market may engage in passive market making transactions
in the common stock on the Nasdaq National Market in accordance with Rule 103
of Regulation M under the Exchange Act, during the business day prior to the
pricing of the offering. Passive market makers must comply with applicable
volume and price limitations and must be identified as such. In general, a
passive market maker must display its bid at a price not in excess of the
highest independent bid for such security; if all independent bids are lowered
below the passive market maker's bid, however, such bid must then be lowered
when certain purchase limits are exceeded.

                         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. as of April 30, 1998 and 1999, and the related consolidated
statements of income, stockholders' equity and cash flows for each of the three
years in the period ended April 30, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements 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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of IMPCO Technologies, Inc. at April 30, 1998 and 1999, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended April 30, 1999, in conformity with accounting principles generally
accepted in the United States.

                   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")
[effective September 15, 1997, AirSensors, Inc. changed its name to IMPCO
Technologies, Inc.] include the accounts of the Company and its majority owned
subsidiary IMPCO-BERU Technologies B.V. ("IMPCO BV") [Effective January 29,
1999, IMPCO Technologies B.V. changed its name to IMPCO-BERU Technologies
B.V.], its majority owned subsidiary Grupo I.M.P.C.O. Mexicano, S. de R.L. de
C.V. ("IMPCO Mexicano") [Effective January 20, 1998, Industrias Mexicanas de
Productos de Combustibles, S. de R.L. de C.V. changed its name to Grupo
I.M.P.C.O. Mexicano, S. de R.L. de C.V.] and its wholly-owned subsidiaries
IMPCO Technologies, Pty. Limited ("IMPCO Pty") and IMPCO Tech Japan K.K.
("IMPCO Japan"). All significant intercompany accounts and transactions have
been eliminated in consolidation.

   The Company is a designer, manufacturer and supplier of fuel storage, fuel
delivery and electronic control systems that allow internal combustion engines
and fuel cells to operate using clean fuels such as hydrogen, propane, natural
gas and methanol.

   (b) Interim Financial Information--The interim financial information at
January 31, 2000 and for the nine months ended January 31, 2000 and 1999 is
unaudited. In the opinion of management, the interim information has been
prepared on the same basis as the annual financial statements and includes all
adjustments (consisting only of normal recurring adjustments) that the Company
considers necessary for a fair presentation of its financial position at such
date and its operating results and cash flows for those periods. Results for
the interim periods are not necessarily indicative of the results to be
expected for the entire year, or any future period.

   (c) 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.

   (d) Property, plant and equipment--Property, plant and equipment 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
financed by the Company's capital lease facility or capital expenditure
facility, is provided using the straight-line method over the shorter of the
assets' estimated useful lives or the lease terms.

   (e) Intangibles arising from acquisitions--Intangibles arising from
acquisitions, primarily goodwill, are recorded based on the excess of the cost
of the acquisition over amounts assigned to tangible assets and liabilities.
Intangible assets arising from acquisitions are amortized using the straight-
line method over their estimated lives of twenty years.

   (f) 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.

   (g) 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.

   (h) Contract revenue recognition--Contract revenue for customer funded
research and development is principally recognized by the percentage of
completion method. Amounts expected to be realized on contracts are based on
the Company's estimates of total contract value and costs at completion. These
estimates are reviewed and revised periodically throughout the lives of the
contracts.

                            IMPCO TECHNOLOGIES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   (i) Minority interests in subsidiaries--In October 1995, IMPCO purchased 51%
of IMPCO BV. In May 1998, IMPCO purchased the remaining 49% of IMPCO BV.
Subsequently, in January 1999, IMPCO sold a 49% share of IMPCO BV. In July
1996, IMPCO acquired IMPCO Pty, which included a 50% share in a subsidiary
("Gas Parts, NSW"). In January 1998, IMPCO Pty acquired the remaining 50% of
Gas Parts, NSW. In January 1999, IMPCO Pty acquired 51% of IMPCO SA. In
December 1997, IMPCO acquired a 90% interest in IMPCO Mexicano. Minority
interests represents the minority stockholder's proportionate share of equity
in the IMPCO BV, Gas Parts, NSW, IMPCO SA and IMPCO Mexicano subsidiaries. The
balance sheet amounts in minority interest at April 30, 1999 and January 31,
2000 represent 49% of the equity held by the single minority stockholder in
IMPCO BV, 10% of the equity held by the single minority stockholder in IMPCO
Mexicano and 49% of the equity held by the single minority stockholder in IMPCO
SA.

   (j) 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, all
common stock equivalents, and if dilutive, shares issued upon conversion of
preferred stock.

   (k) Stock based compensation--In October 1995, the Financial Accounting
Standards Board issued SFAS No. 123 "Accounting of Stock Based Compensation,"
which established accounting and reporting standards for stock based employee
compensation plans effective after fiscal year 1996. SFAS 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. Such
entities who elect 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
123, but has provided pro forma disclosures (see note 7).

   (l) 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.

   (m) Use of estimates--The preparation of financial statements in conformity
with generally accepted accounting principles 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.

   (n) Reclassifications--Certain prior year amounts have been reclassified to
conform to current presentations.

   (o) 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.

   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

                                      F-9

                            IMPCO TECHNOLOGIES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

foreign currency commitment, are included in the results of operations as
incurred.

   (p) Financial instruments--The Company's financial instruments recorded on
the balance sheet include short-term bank debt and long-term bank debt. At
April 30, 1999 and January 31, 2000, off balance sheet derivative financial
instruments included foreign currency forward contracts and interest rate swap
agreements (see note 4).

   The Company enters into foreign currency forward contracts to hedge
indentifiable 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.

   Interest rate swap agreements are used by the Company 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.

Accounting Pronouncements

   The Financial Accounting Standards Board has issued certain Statements of
Financial Accounting Standards (SFAS) which are applicable to the Company. SFAS
130, "Reporting Comprehensive Income," which was effective for fiscal years
beginning after December 15, 1997; SFAS 131, "Disclosures About Segments of an
Enterprise and Related Information," which is effective for fiscal years
beginning after December 15, 1997; and, SFAS 133, "Accounting for Derivative
Instruments and for Hedging Activities," which is effective for fiscal years
beginning after June 15, 1999.

   SFAS 130 requires that all items required to be recognized under accounting
standards as components of comprehensive income be reported in a financial
statement that is displayed with the same prominence as other financial
statements. The changes in cumulative translation adjustments, reported through
stockholders' equity, is currently the Company's only component of
comprehensive income. The Company adopted this standard in fiscal year 1999.

   SFAS 131 requires a public enterprise to report financial and descriptive
information about its reportable operating segments based upon the manner in
which management organizes segments within the enterprise for making operating
decisions and assessing performances. The Company adopted this standard in
fiscal year 1999 (see Note 10).

   SFAS 133 requires derivatives to be recorded on the balance sheet at fair
value and establishes special accounting for the following three types of
hedges: hedges of changes in the fair value of assets, liabilities or firm
commitments (referred to as fair value hedges); hedges of the variable cash
flows of forecasted transactions (cash flow hedges); and hedges of foreign
currency exposures of net investments in foreign operations. The accounting
treatment and criteria for each of the three types of hedges is unique. Changes
in fair value of derivatives that do not meet the criteria of one of these
three categories of hedges would be included in income. SFAS 133 was amended by
SFAS 137, which delayed its effective date. The Company has not determined what
impact, if any, it will have on its financial position, results of operations
and cash flows. Currently, the Company does not anticipate adopting this
standard before May 1, 2001.

Compensation." The Interpretation addresses implementation practice issues in
accounting for compensation costs under existing rules prescribed by Accounting
Principles Board No. 25. The new 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 is considering the effects
these changes make and will implement any changes to their plans as deemed
appropriate.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements," or
SAB 101. SAB 101 summarizes certain of the SEC Staff's views in applying
generally accepted accounting principles to revenue recognition in financial
statements. The Company is currently evaluating the impact of SAB 101. The
Company does not believe that their evaluation will result in any material
change to their revenue recognition policies.

2. Acquisitions

   Ateco Automotive Pty. Ltd. On July 1, 1996, the Company acquired certain
operating assets of Ateco Automotive Pty. Ltd. ("Ateco") for approximately
US$6,500,000. Ateco, an Australian private company, has distributed IMPCO's
gaseous fuel carburetion systems and related devices for use with internal
combustion engines since 1969 through its Gas Division near Melbourne,
Australia.

   In order to effectuate the transaction, IMPCO established a wholly-owned
subsidiary in Australia, IMPCO Technologies Pty. Limited ("IMPCO Pty"). The
acquisition of Ateco has been accounted for under the purchase method of
accounting and the acquired operations have been included in the consolidated
financial statements since the date of acquisition. The assets acquired by
IMPCO Pty primarily consist of accounts receivable, inventories, equipment, a
note, business goodwill, distribution rights in Australia, and a 50% interest
in Ateco's sub-distributor, Gas Parts, NSW.

   The purchase price was financed through approximately $4,000,000 of term
loans provided by Bank of America NT&SA and its Sydney Australia Branch. The
term loans are both three-year loans with a five-year amortization schedule and
interest at market rates. In addition, accounts receivable due to IMPCO by
Ateco, totaling approximately $1,852,000, were offset against the purchase
price. The balance of the purchase price was paid with proceeds from IMPCO's
then existing line of credit with Bank of America NT&SA. The Company recognized
approximately $3,601,000 of intangible assets arising from acquisitions, which
is being amortized over 20 years.

   IMPCO Technologies B.V. On October 31, 1995, the Company acquired 51% of the
outstanding stock of Media, a private company in the Netherlands, from
Centradas B.V., a private company in the Netherlands, for cash in the amount of
fl.3,187,500 (US$2,023,000). IMPCO BV has distributed IMPCO's gaseous fuel
carburetion systems and related devices for use in internal combustion engines
since 1972. IMPCO BV services the European marketplace from its headquarters in
the Netherlands and through its subsidiaries in Germany, France and the United
Kingdom.

   This acquisition was financed through a term loan provided by Bank of
America NT&SA which is being repaid over a five-year period with interest at
market rates [See Note 3]. The acquisition of IMPCO BV has been accounted for
under the purchase method of accounting and has been included in the
consolidated financial statements since the date of acquisition. The Company
recognized $2,100,000 of intangible assets arising from the acquisition which
is being amortized on the straight-line method over 20 years.

   On May 1, 1998 the Company purchased the remaining 49% of IMPCO BV from Depa
Holding B.V. for fl.1,400,000 (US$692,521). As a condition precedent to the
purchase of the outstanding shares, IMPCO BV retired the debt outstanding to
Depa Holding B.V. with the proceeds from the term loan granted by Bank of
America NT&SA (See Note 3).

day, the Company acquired a 90% interest in Industrias Mexicanas de Productos
de Combustibles, S. de R.L. de C.V. The purchase price of $961,000 was paid in
cash. Immediately prior to the Company's acquisition of a 90% ownership
interest in Grupo I.M.P.C.O. Mexicano, Grupo I.M.P.C.O. Mexicano acquired
certain operating assets of the carburetion division of Algas Mexicana, de R.L.
de C.V. These acquisitions were financed by term loans of approximately $3.3
million provided by Bank of America NT&SA.

   Edo Canada, Ltd. On December 12, 1997, the Company purchased from the
bankruptcy trustee of EDO Canada, Ltd. certain development, testing, quality
control and manufacturing equipment used for the manufacture of storage tanks
for compressed natural gas. The purchase price of US$790,000 was paid in cash
and was primarily financed through Bank of America's BA Capital Leasing.

   Gas Parts (NSW) Pty. Ltd. On January 31, 1998, the Company's wholly-owned
subsidiary, IMPCO Pty, acquired the remaining 50% ownership interest in Gas
Parts for A$225,000 (US$148,500) in cash. This acquisition was accounted for
using the purchase method of accounting for step-acquisitions. Excess purchase
price over fair market value of the underlying assets was allocated to
goodwill.

   Crusader Engine Division. On December 4, 1998, the Company acquired certain
operating assets of the Crusader Engine division of Thermo Power Corporation, a
subsidiary of Thermo Power Electron Corporation, for approximately $3,880,000.
The Crusader Engine division provides engine dressing and related devices for
material handling engines. The Company funded $3,190,000 of the purchase price
using the Bank of America NT&SA acquisition facility and $710,000 using the
Bank of America NT&SA capital lease facility. These assets currently comprise
the Company's Industrial Engine Systems business. This acquisition was
accounted for under the purchase method of accounting and has been included in
the consolidated financial statements since the date of acquisition. Goodwill
of approximately $662,000 was recognized with tangible net assets acquired
consisting of $2,500,000 in inventory and $718,000 in fixed assets.

   Mikuni Corporation. In March 1999, the Company purchased a dormant company
in Japan for US$126,000 in order to establish IMPCO Tech Japan K.K. (IMPCO
Japan). On March 31, 1999, IMPCO Japan, purchased certain manufacturing
equipment and inventory of the Fukuoka Division of Mikuni Corporation. The
purchase price of US$1,325,000 was paid in cash. The acquisition was financed
through a yen-denominated term loan provided by the Hong Kong and Shanghai
Banking Corporation, Osaka Branch, which is being repaid over a five-year
period with interest at market rates [See Note 3]. This acquisition was
accounted for under the purchase method of accounting and has been included in
the consolidated financial statements since the date of acquisition. Goodwill
of approximately $944,000 was recognized with tangible net assets acquired
consisting of $362,000 in inventory and $19,000 in fixed and other assets.

 (a) Bank of America NT&SA

   At April 30, 1999, IMPCO's credit facility with Bank of America NT&SA (Bank)
included a $12 million revolving line of credit, a $6,000,000 term loan
facility for possible future acquisitions, a $6,525,000 capital lease facility
and a standby letter of credit to expire August 31, 2000. The credit facility
provided a Mexican peso line of credit equivalent to $1,000,000 for IMPCO
Mexicano and was included as part of the revolving line of credit. The standby
letter of credit was used to guarantee the credit facilities granted by the
Hong Kong and Shanghai Banking Corporation Ltd., Osaka Branch (refer to (d)
below).

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   Also as of April 30, 1999, IMPCO BV has a credit facility with Bank of
America NT&SA through its Amsterdam branch. The facility includes a term loan
for $2,100,000 or an equivalent amount in freely convertible foreign
currencies.

   On September 13, 1999, IMPCO amended its credit facility with Bank of
America NT&SA by increasing the revolving line of credit to $20 million and
extending the term for a twelve month period ending August 31, 2001. The
amended credit facility also added a $6,000,000 non-revolving line of credit
(due August 31, 2000) for possible future acquisitions, a $3,000,000 non-
revolving line of credit for future capital expenditures (due August 31, 2000)
and a Mexican peso line of credit equivalent to $3,000,000 (due August 31,
2001) for IMPCO Mexicano. Those portions of the credit facility that are due
August 31, 2000 have an option to convert each of them to a term loan payable
in five years. The Company intends to exercise this option.

   Including the revolving line of credit, the capital expenditures facilities,
the capital lease facility, the standby letter of credit and the acquisition
facilities, the total Bank of America NT&SA credit facility was approximately
$27,444,000 at April 30, 1999 and $39,091,000 at January 31, 2000. Details
about each of the components of the Company's credit facility at April 30, 1999
and January 31, 2000 follows. Term loans obtained for prior acquisitions are
also described.

   Revolving Line of Credit. The $12 million revolving line of credit at April
30, 1999 bore interest, payable monthly, at a fluctuating per annum rate equal
to the Bank's reference rate minus one-half of one percentage point (7.25% on
April 30, 1999). The Company could elect to have all or portions of the line
bear interest at an alternative interest rate established by the Bank (offshore
rate). The offshore rate was 6.16% on April 30, 1999. Of the $5,360,000
outstanding line of credit balance at April 30, 1999, 860,000 was subject to
the reference rate and $4,500,000 was subject to the offshore rate.

   For U.S. borrowings under the Mexican portion of the revolving credit line
at April 30, 1999, interest, payable monthly, was at a fluctuating per annum
rate equal to the Bank's reference rate or the London Interbank Offering Rate
(LIBOR) plus 1.75% (6.6525% at April 30, 1999). For Mexican borrowings, under
the revolving line of credit at April 30, 1999, interest, payable monthly, was
at a fluctuating per annum rate equal to the Bank of America Mexico (BAMSA)
cost of funds plus 1.50% or the TIIE plus 1.50% (23.59% at April 30, 1999). The
TIIE is the Interbank Interest Equilibrium Rate calculated by the Bank of
Mexico for the most recent period of twenty-eight (28) days prior to
commencement of the interest period. The Company may prepay the facility, in
full or in part, upon two-business days notice, subject to break funding costs,
if any. The minimum prepayment was US$250,000. At April 30, 1999, the total
outstanding line of credit balance of $107,000 was subject to the BAMSA cost of
funds rate of 26.25%.

   The amended revolving line of credit bears interest, payable monthly, at a
fluctuating rate per annum equal to the Bank's reference rate minus one-half to
one-quarter of one percentage point, depending on certain financial ratios, as
defined. Alternatively, the Company may elect to have all or portions of the
line based on an offshore rate, which may also vary depending on certain
financial ratios, as defined. At January 31, 2000, the outstanding line of
credit balance was $13,000,000 of which $1,000,000 was subject to the Bank's
reference rate less .50%, or 8.00%. Additionally, $7,000,000 and $5,000,000
were subject to the offshore rate of 7.43% and 7.11%, respectively. The Mexican
peso line of credit at January 31, 2000 totaled $643,000 and was subject to a
rate based on the BAMSA cost of funds of 22.00% (See description of rate
above).

   It is management's intent to renew the amount of its present long-term
obligation under the revolving line of credit for an uninterrupted period
extending beyond one year from the balance sheet date.

   The amended facility may be used for financing commercial letters of credit
with a maximum maturity of 180 days and standby letters of credit with a
maximum maturity of five years not to extend beyond August 30, 2002. The amount
of letters of credit outstanding at any one time may not exceed $1,000,000 for
commercial

letters of credit and $750,000 for standby letters of credit. The maximum
amount available at any one time on the revolving line of credit and the
commercial letters of credit is $20,000,000. At January 31, 2000, a standby
letter of credit totaling $375,000 was outstanding. At April 30, 1999, a
standby letter of credit under the previous credit facility totaling $375,000
was outstanding.

   Term Loan for Acquisition of Media. This term loan bears interest, payable
on a monthly basis, at the Bank's reference rate. The Company may elect to have
all or portions of the term loan bear interest at an alternative interest rate
agreed upon by the Bank and IMPCO for periods of not less than 30 days nor more
than one year. The alternative interest rate is based on the offshore rate plus
1.50%. Each alternative rate portion must be for an amount not less than
$500,000 and may not include any portion of principal that is scheduled to be
repaid before the last day of the applicable interest period. On October 20,
1997, the Company entered into a 34 month interest rate swap agreement with
Bank of America NT&SA ending August 31, 2000, that fixes the interest rate on
the facility at 7.90%. At April 30, 1999, the total outstanding balance was
$615,000. At January 31, 2000, the total outstanding balance was approximately
$308,000.

   Term Loan for the Acquisition of ALGAS. This term loan bears interest,
payable on a monthly basis, at the Bank's reference rate. The Company may elect
to have all or portions of the term loan bear interest at an alternative
interest rate agreed upon by the Bank and IMPCO for periods of not less than 30
days nor more than one year. The alternative interest rate is based on the
offshore rate plus 1.75%. Each alternative rate portion must be for an amount
not less than $500,000 and may not include any portion of principal that is
scheduled to be repaid before the last day of the applicable interest period.
On February 3, 1998, the Company entered into a 58-month interest rate swap
agreement with the Bank ending December 5, 2002 that fixes the interest rate on
the facility at 7.74%. At April 30, 1999, the total outstanding balance was,
$2,475,000. At January 31, 2000, the total outstanding balance was $1,980,000.

   Term Loan for the Acquisition of IMPCO BV.  This term loan bears interest,
payable on a monthly basis, at the Bank's reference rate. The Company may elect
to have all or portions of the term loan bear interest at an alternative
interest rate agreed upon by the Bank and IMPCO for periods of not less than 30
days nor more than one year. The alternative interest rate is based on the
offshore rate plus 1.75%. Each alternative rate portion must be for an amount
not less than $500,000 and may not include any portion of principal that is
scheduled to be repaid before the last day of the applicable interest period.
On May 29, 1998, the Company entered into a 59-month interest rate swap
agreement with the Bank ending April 15, 2003 that fixes the interest rate on
the facility at 7.80%. At April 30, 1999, the total outstanding balance was
$554,000. At January 31, 2000, the total outstanding balance was $485,000.

   IMPCO BV Term Loan. On April 29, 1998 IMPCO BV entered into a credit
facility with Bank of America NT&SA through its Amsterdam branch. The facility
includes a term loan for $2,100,000 or an equivalent amount in freely
convertible foreign currencies. On May 1, 1998 IMPCO BV borrowed fl.4,200,000
to refinance the existing term loan with Depa Holdings as a condition precedent
to the sale of the minority shares in IMPCO BV. This term loan bears interest,
payable on a monthly basis, at the Euro Interbank Offered Rate for the
corresponding period of the advance, plus 1.50%. The Company will repay
principal in 20 successive quarterly installments. The first 19 installments
will be equal to fl.210,000 with the last installment equal to the remaining
balance. The term loan may be prepaid, with payments applied in inverse order
of maturity, in whole or in part, at any time. At April 30, 1999, the
outstanding balance of fl.3,570,000 (US$1,714,000) bore an interest rate of
4.27%. At January 31, 2000, the outstanding balance of fl.2,730,000
(US$1,202,000) bore an interest rate of 5.00%.

   Term Loans for Future Acquisition(s). At April 30, 1999 the term loan

days nor more than one year. The alternative interest rate was based on the
offshore rate plus 1.50%. Each alternative rate portion was for an amount not
less than $500,000 and may not include any portion of principal that is
scheduled to be repaid before the last day of the applicable interest period.
The Company is repaying principal in 20 successive quarterly installments,
starting on the last day of the third month after funding. The first 19
installments are equal to 1/19 of the original principal amount with the last
installment equal to the remaining balance. The term loan may be prepaid, with
payments applied in inverse order of maturity, in whole or in part, at any
time.

   On December 4, 1998 the Company used $3,190,000 of the then existing
$6,000,000 term loan for the acquisition of Crusader Engines. On February 12,
1999 the Company made a partial prepayment on this loan in the amount of
$1,800,000. At April 30, 1999, the outstanding balance of $1,231,000 was
subject to the offshore rate of 6.52%. At January 31, 2000 the outstanding
balance was $752,000, subject to a fixed interest rate of 7.61%.

   In accordance with the amended credit facility on September 13, 1999, the
Company obtained a new $6,000,000 non-revolving line of credit for possible
future acquisitions due August 31, 2000. This line of credit bears interest at
the Bank's reference rate or an optional offshore rate. There were no amounts
outstanding under this loan at January 31, 2000.

   Capital Lease and Expenditure Facilities. The capital lease facility at
April 30, 1999 was available in incremental draws of $50,000 or more to finance
acquisitions of equipment such as machinery, dies, molds, office furniture, and
motor vehicles. At April 30, 1999, approximately $2,928,000 was outstanding
under the capital lease facility. Each draw is being repaid in twenty
consecutive quarterly installments. Each draw bears interest at either a
variable rate or fixed rate of interest. The fixed rate of interest was the
U.S. Treasury note bond-equivalent yield per annum corresponding to the number
of months remaining on the draw, plus 2.40 percentage points. The variable rate
of interest was equal to Bank's London Branch 3-month LIBOR rate plus 2.00
percentage points. At April 30, 1999, all draws were subject to the variable
rate of interest. The short-term portion of the capital lease facility is
included in current maturities of short-term debt on the Company's balance
sheet. On May 29, 1998, the Company entered into a 59-month interest rate swap
agreement with Bank of America NT&SA ending April 15, 2003 that fixes the
interest rate on $2,578,000 of the facility at 8.50% for fundings 1 through 18,
8.20% for fundings 19 through 24 and 8.05% for funding 25 through 29. At
January 31, 2000 no further borrowings were available under this capital lease
facility in accordance with the amended credit facility.

   If the Company exercises an early termination option before the scheduled
expiration date of a capital lease, a termination charge will be assessed. The
termination charge is a sliding percentage (not to exceed 3%) of the balance on
the lease at time of termination.

   At January 31, 2000, approximately $2,365,000 was outstanding under this
facility, of which approximately $480,000 was fixed at 8.50% and approximately
$862,000 was fixed at 8.20%. The remaining balance of approximately $1,023,000
was subject to the variable rate of interest based on Bank of America's London
Branch 3-month LIBOR rate plus 2.15 percentage points (8.08% as of January 31,
2000).

   The amended credit facility provides for a $3,000,000 non-revolving capital
expenditure line of credit due August 31, 2000. This line of credit bears
interest at the Bank's reference rate or an optional offshore rate. At January
31, 2000, the outstanding balance was $1,725,000 bearing interest at 7.37%.

   Standby Letter of Credit. In order to secure yen denominated credit
facilities for IMPCO Japan, the Company was required to post a standby letter
of credit for the total available credit facility granted by the Hong Kong and
Shanghai Banking Corporation Ltd., Osaka Branch. The original amount of the
facility is (Yen)220,000,000 (US$1,833,000) and will decrease quarterly as
payments are made on the underlying outstanding

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

debt. The cost of the facility is 1.00% per annum of the amount outstanding. On
April 30, 1999, the amount outstanding under the standby letter of credit was
$1,844,000. On January 31, 2000, the amount outstanding under the standby
letter of credit was $1,825,000.

   Loan Covenants And Collateral. The Bank's credit facility contains certain
restrictions and financial covenants, including liquidity, tangible net worth
and cash flow coverage thresholds, as well as limitations on other
indebtedness, and is secured by substantially all of the Company's assets. At
April 30, 1999 and January 31, 2000, the Company was in compliance with all
covenants.

 (b) Term Loan--Depa Holding B.V.

   On May 1, 1998, as a condition precedent to the sale of the minority shares
held by Depa Holding B.V., IMPCO BV retired this facility from the proceeds of
the term loan facility granted by Bank of America NT&SA.

 (c) Credit Facility--Mees Pierson

   In February 1996, IMPCO BV secured a fl. 3,000,000 (US$1,440,300) revocable
credit facility with Mees Pierson, a financial institution in the Netherlands.
The interest rate is determined weekly based on a weighted average of several
money market indices. IMPCO BV's borrowings under this facility may not exceed
the combined total of a specified amount of its accounts receivable (70% of
book value) and inventory (50% of book value). At April 30, 1999, the interest
rate was 5.25% and there was no outstanding balance on the credit facility. At
January 31, 2000, there was no outstanding balance.

 (d) The Hong Kong and Shanghai Banking Corporation Ltd.

   Term Loan for the Acquisition of Mikuni. On March 29, 1999, IMPCO Japan
secured a (Yen)160,000,000 (US$1,490,000) term loan facility with the Hong Kong
and Shanghai Banking Corporation Ltd., Osaka Branch. This term loan bears
interest, payable on a quarterly basis, at the Euroyen London Interbank Offer
Rate plus 1.60%. The Company may elect to lock the interest rate on the loan
for periods of not less than 30 days nor more than 6 months. At April 30, 1999,
the outstanding loan balance of (Yen)160,000,000 (US$1,341,000) bore an
interest rate of 1.794%. At January 31, 2000, the outstanding loan balance of
(Yen)136,000,000 (US$1,267,000) bore an interest rate of 1.905%.

   Line of Credit. On March 29, 1999, IMPCO Japan secured a (Yen)60,000,000
(US$559,000) revolving term loan facility with the Hong Kong and Shanghai
Banking Corporation Ltd., Osaka Branch. This term loan bears interest, payable
on a quarterly basis, at the Euroyen London Interbank Offer Rate plus 1.60%.
The Company may elect to lock the interest rate on the loan for periods of not
less than 30 days nor more than 6 months. At April 30, 1999, the outstanding
loan balance of (Yen)10,000,000 (US$84,000) bore an interest rate of 1.794%. At
January 31, 2000, the outstanding loan balance of (Yen)50,000,000 (US$466,000)
bore an interest rate of 1.902%.

   Annual maturities of long-term debt, excluding capital leases (see Note 6)
for the five years subsequent to May 1, 1999 are as follows: 2000-$2,400,000;
2001-$7,700,000; 2002-$1,300,000; 2003-$1,200,000; 2004-$500,000; and
thereafter-$300,000.

4. Derivative Financial Instruments and Fair Value of Financial Instruments

   The Company uses derivative financial instruments for the purpose of
reducing its 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. The Company is not a party to leveraged derivatives and does not
hold or issue financial instruments for speculative purposes.

                            IMPCO TECHNOLOGIES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   Foreign Currency Management. 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 Company's exposure
to fluctuations in currency exchange rates has increased as a result of the
growth of its international subsidiaries. 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 monitors this risk
and attempts to minimize the exposure through forward currency contracts and
the management of cash disbursements in local currencies. The Company uses
forward currency contracts, which typically expire within one year, to hedge
payments of identifiable foreign currency commitments by its international
subsidiaries. Realized gains and losses on these contracts are included in the
measurement of the related foreign currency. At April 30, 1999 and January 31,
2000, the Company had forward currency contracts approximately US$2,400,000 and
US$382,000, respectively. At April 30, 1999 and January 31, 2000, the fair
value of forward currency contracts was approximately ($99,000) and $14,000,
respectively.

   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.

   Interest Rate Management. The Company uses interest rate swap agreements
with Bank of America NT&SA to manage its exposure to interest rate changes and
stabilize the cost of borrowed funds. When an agreement is executed, the
interest rate swap is matched as a hedge to a specific debt instrument and has
the same notional amount and tenor as the related debt instrument principal.
Since the interest rate instruments effectively hedge the underlying interest
rate exposure, the net cash amounts paid or received on the agreements are
accrued and recognized as an adjustment to interest expense. At April 30, 1999,
the Company had $5,555,000 secured under fixed interest rate agreements at a
weighted-average fixed interest rate of 7.97%. Absent these fixed rate
agreements, the weighted-average variable rate for this debt at April 30, 1999
would have been 6.84%. Fair value of these instruments is based on estimated
current settlement cost. At April 30, 1999, the fair value of interest rate
swap agreements was approximately ($59,000). At January 31, 2000, the amount
was not material.

   Fair Value of Financial Instruments. Because of the short maturity, short-
term bank debt approximates fair value. The fair value of the Company's long-
term debt is estimated using discounted cash flows based on the Company's
incremental borrowing rates for similar types of borrowings. At April 30, 1999,
the fair value of the Company's long-term debt approximated carrying value.

5. Income Taxes

   The provision for income taxes consists of the following:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

1998, and 1999, the current provision for state taxes was reduced by using
approximately $246,000, $375,000 and $516,000, respectively, of investment
and/or research tax credits.

   For interim periods, the provision for income taxes is based upon the
estimated annual income tax rate for the full fiscal year, including
consideration of the research credits.

   During the fourth quarter of fiscal year 1997, the Company reevaluated the
valuation allowance for its deferred tax assets. Based on this reevaluation,
which considered among other items, projections as to future taxable income,
the Company determined that the valuation allowance should be reduced by
$1,559,000, principally due to the presumed future use of federal net operating
loss carryforwards. This reduction in the valuation allowance is reflected in
the deferred tax benefit for fiscal year 1997. During fiscal year 1998, the
Company determined that no valuation allowance was required and therefore
reduced the valuation allowance by $510,000. Management has determined, based
on the Company's history of prior operating earnings and its expectations of
future earnings, that operating income of the Company will more likely than not
be sufficient to recognize fully these net deferred tax assets and that the
estimated effective annual rate in the future years will approximate the
statutory rate.

   During the third quarter of fiscal year 1999, the Company realized a foreign
tax credit of approximately $595,200 from the 49% sale of its IMPCO BV
subsidiary.

   A reconciliation of income taxes computed at the federal statutory income
tax rate to income taxes reported in the consolidated statements of income is
as follows:

   The Company used a $3,000,000 capital lease facility to finance acquisitions
of equipment such as machinery, dies, molds and patterns, office furniture and
fixtures and motor vehicles. At April 30, 1998 and 1999, and January 31, 2000,
approximately $2,625,000, $2,946,000 and $2,365,000 was outstanding under the
capital lease facility, respectively. At April 30, 1998, the gross and net
assets acquired under the capital lease facility was approximately $3,854,000
and $2,131,000, respectively. At April 30, 1999, the gross and net assets
acquired under the capital lease facility was approximately $5,224,000 and

 (b) Contingencies

   The Company is currently subject to certain legal proceedings and claims
arising in the ordinary course of business. Based on discussions with legal
counsel, management does not believe that the outcome of any of these matters
will have a materially adverse effect on the Company's consolidated financial
statements.

 (c) Investment and Tax Savings Plan

   The Company's Investment and Tax Savings Plan (the "Plan") is a defined
contribution plan, which is qualified under Internal Revenue Service Code
Section 401(k). The Plan is subject to the provisions of the Employee
Retirement Income Security Act of 1974. All employees who are at least age
twenty-one or older are eligible to participate in the Plan on the first day of
any calendar month following one year of service with the Company. Employees of
the Company who elect to participate in the Plan may contribute into the Plan
not less than 1% nor more than 15% of compensation. The Company's matching
contributions are discretionary and match elective salary deferrals up to 1.8%
of compensation. Approximately 46% of eligible employees were enrolled in the
401(k) plan at April 30, 1999. Employer contributions approximated $95,000,
$98,000 and $122,000 for fiscal years ended 1997, 1998 and 1999, and $363,000
for the nine months ended January 31, 2000.

7. Stockholders' Equity

 (a) 1993 Series 1 Preferred Stock

   The holders of the Company's 1993 Series 1 Preferred Stock ("Preferred
Stock") were entitled to receive annual cumulative dividends of up to $105 per
share and not less than $80 per share ($100 per share at April 30, 1999). The
dividend rate, which was adjusted on the first day of each calendar quarter,
was based on the Seafirst Bank prime rate of interest plus 1.5 % (assuming a
deemed principal value of $1,000 per share).

   Commencing March 31, 1999, the Company had the right to convert the
Preferred Stock into common stock if the average market price for the common
stock for the immediately preceding 30 trading days equals or exceeds the
conversion price then in effect and the Company pays all accrued dividends. On
March 31, 1999, in accordance with its conversion right, the Company converted
5,950 shares of Preferred Stock into 1,124,764 shares of common stock and paid
all accrued dividends. The Preferred Stock was convertible into common stock by
dividing the conversion price at March 31, 1999 into its liquidation value of
$1,000 for each share being converted, which resulted in a conversion price of
$5.29 per share.

 (b) Stock options

   The Company has five 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 4 or 5 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.

   At April 30, 1999, there were 30,494 shares available for future grant.

   The Company has elected to account for its employee stock options under
Accounting Principles Board Opinion 25, "Accounting for Stock Issued to
Employees" (APB 25) and related Interpretations in accounting for 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.

   SFAS 123 requires "as adjusted" 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:

(1) On March 31, 1999, all outstanding preferred stock was converted to common
    stock and the diluted Earnings Per Share is calculated as though the
    conversion occurred at the beginning of the fiscal year. The basic earnings
    per share is calculated with weighted average shares based on the
    conversion at March 31, 1999. The convertible preferred shares is equal to
    the full conversion (1,124,764 shares) less the weighted average shares
    outstanding for the month of April 1999 (92,446 shares).

   For additional disclosures regarding the employee stock options, see Note 7.
Options to purchase 60,000 shares of common stock at $16.25 were outstanding
during fiscal year 1999 and options to purchase 260,000 shares of common stock
at prices ranging from $10.88 to $11.78 were outstanding during fiscal year
1998 but were not included in the computation of diluted earnings per share
because the options' exercise price was greater than the average market price
of the common shares and, therefore, the effect would be anti-dilutive.

9. Revenues

   During fiscal year 1998, the IMPCO BV, IMPCO Pty and IMPCO Mexicano
subsidiaries accounted for approximately 16%, 10% and 1% of total consolidated
revenues, respectively, and contract revenue accounted for approximately 12% of
consolidated revenues. During fiscal year 1999, the IMPCO BV, IMPCO Pty, Grupo
IMPCO Mexicano and IMPCO Japan subsidiaries accounted for approximately 15%,
6%, 3% and less than 1% of total consolidated revenues, respectively, and
contract revenue accounted for approximately 13% of consolidated revenues. For
the nine months ended January 31, 2000, the IMPCO BV, IMPCO Pty, Grupo IMPCO
Mexicano and IMPCO Japan subsidiaries accounted for approximately 12%, 5%, 6%
and less than 3% of total consolidated revenues, respectively, and contract
revenue accounted for approximately 8% of consolidated revenues. During fiscal
year 1998 and 1999, and for the nine months ended January 31, 2000, General
Motors Corporation, and customers associated with the General Motors program,
accounted for approximately 15%, 28% and 18%, respectively, of consolidated
revenues. During fiscal year 1997, no single unaffiliated customer exceeded 10%
of consolidated revenues.

   The Company routinely sells products to a broad base of domestic and
international customers, which includes distributors and original equipment
manufacturers. Based on the nature of these customers, credit is generally
granted without collateral being required. Management does not anticipate that
a significant credit risk exists as a result of these customer relationships.

10. Business Segment And Geographic Information

   Business Segments. The Company currently operates in three operating
segments: Automotive OEM division, Gaseous Fuel Products division and
International Operations. The Automotive OEM division generates revenues
through the sale of fuel metering, storage and electronic control systems to
original equipment manufacturers (OEMs) and the installation of our products
into OEM vehicles. The division also generates contract revenue by providing
engineering design and support to the OEMs so that our fuel system will fit
into a variety of their vehicles as they upgrade their models each year. The
Gaseous Fuel Products division sells products including parts and conversion
systems to OEMs and the aftermarket. The Company's International Operations in
Australia, Europe, Japan and Mexico provide distribution for the Company's
products, predominantly from its Gaseous Fuel Products division and some
product assembly.

   Corporate expenses consist of general and administrative expenses at the
corporate level and includes the amortization of goodwill and other intangible
assets. Intersegment eliminations are primarily the result of intercompany
sales from our Gaseous Fuel Products division to our International Operations.

   All research and development is expensed as incurred. Research and
development expense includes both customer funded research and development and
company sponsored research and development. Customer funded research and
development consists primarily of expenses associated with contract revenue.
These expenses include applications development costs in the Automotive OEM
division funded under customer contracts.

   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.

15. Other Matters

   In April 1997, the Company sold air pollution control devices to its
subsidiary, IMPCO BV, a Netherlands corporation. This subsidiary then sold the
goods to Sagace Holland B.V., another Netherlands corporation, which reexported
the goods to Iran, contrary to U.S. licenses authorizing the initial export of
the goods from the United States. The sales involved approximately 150 units of
emission control equipment used on forklifts or similar vehicles that operate
on compressed natural gas with a value of approximately $350,000. These events
were voluntarily reported by the Company to the Office of Export Enforcement,
U.S. Department of Commerce, and the Office of Foreign Assets Control, U.S.
Department of the Treasury, in August 1997.

   Subsequent to reporting the foregoing events, the Company learned that in
April 1997, the Company sold similar air pollution control devices with a value
of approximately $100,000 to a distributor. The distributor then reexported
these goods to Iran, again contrary to U.S. export licenses. These events were
also voluntarily disclosed by the Company to the same Federal agencies in 1998.

   During the fiscal quarter ended January 31, 2000, the Company reached a
settlement agreement with the Office of Foreign Assets Control, Department of
Treasury, concerning the violation of certain U.S. Government export
regulations. Under the terms of the settlement agreement, the Company made a
cash payment of $11,000 as payment in full resolving all matters.

16. Subsequent Event (Unaudited)

   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 to
purchase one share of common stock. The dividend was paid on July 26, 1999 to
stockholders of record on July 12, 1999.

Item 15. Indemnification of Directors and Officers

   Section 145 of the DGCL contains detailed provisions on indemnification of
directors and officers against expenses, judgments, fines and amounts paid in
settlement, actually and reasonably incurred in connection with legal
proceedings. Section 102(a)(7) of the DGCL permits a provision in the
certificate of incorporation of each corporation organized thereunder, such as
the 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. The Certificate of
Incorporation of the Company eliminates the liability of each of its directors
to its stockholders or the Company for monetary damages for breach of fiduciary
duty to the full extent provided by the Delaware General Corporation Law (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.
Indemnification may include all expenses (including attorneys' fees, judgments,
fines, ERISA excise taxes and amounts paid in settlement) reasonably incurred
by the indemnified person.

Item 16. Exhibits

   See Exhibit Index.

Item 17. Undertakings

   We hereby undertake that:

   (1) For purposes of determining any liability under the Securities Act of
1933, as amended (the "Securities Act"), each filing of our annual report
pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of
1934 (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that
is incorporated by reference to this Registration Statement shall be deemed to
be a new registration statement relating to the securities offered therein, and
the

                                      II-1
<PAGE>

offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof;

   (2) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to our directors, officers and controlling persons
pursuant to the Delaware General Corporation Code, our Certificate of
Incorporation or the Bylaws, indemnification agreements entered into between us
and our officers and directors, the Underwriting Agreement and all prior
underwriting agreements, or otherwise, we have 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 us of expenses incurred or paid by a
director, officer or controlling person 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
hereunder, we will, unless in the opinion of our counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question of whether such indemnification by us is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue;

   (3) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by us pursuant to Rule 424(b)(1) or (4) or 497(h) under the
Securities Act shall be deemed to be part of this Registration Statement as of
the time it was declared effective; and

   (4) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be
deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                         IMPCO AND GM TEAMING AGREEMENT

     THIS AGREEMENT is entered as of the 30th day of July, 1997, by and between
IMPCO, Inc. ("IMPCO"), a Delaware corporation with offices at 16804 Gridley
Place, Cerritos, CA 90701, and General Motors Corporation, VDTO - Research &
Development ("GM"), a Delaware corporation with offices at 30500 Mound Road,
Warren, Michigan, USA 48090-9055.
                                     PURPOSE
                                     -------
     The Purpose of this Teaming Agreement is to set forth the terms and
conditions under which the Parties agree to work together in a strategic
alliance, leveraging complementary background, experience and technology, in
order to enhance their respective core competencies and jointly speed further
development of car and truck gaseous fuel propulsion systems for internal
combustion engines ("gaseous fuel propulsion systems") and related components.
The agreed relationship includes (i) business processes for identification of
gaseous fuel propulsion systems and related components on which cooperative
effort, possibly including sharing of staff and resources, is to be directed,
(ii) relative roles and responsibilities, (iii) business terms of general
applicability to purchase and sale between the Parties of gaseous fuel
propulsion systems and related components, and (iv) arrangements for aftersale
support of GM production vehicles utilizing gaseous fuel propulsion systems and
related components by GM independent authorized dealers. This Teaming Agreement
further sets forth alternatives for production and application of components
developed hereunder.

     With this Agreement, the Parties seek to share a process for successful
development and implementation of gaseous fuel propulsion systems and related

                                       1
<PAGE>

components which are state-of-the-art technology; satisfactory to customers and
regulators; able to meet world class quality, reliability, maintainability and
durability; and cost efficient and commercially viable throughout their life
cycle, including after-sale support.

     NOW, THEREFOR, for and in consideration of the promises and the mutual
covenant herein contained, IMPCO and GM hereby set forth their agreement as
follows:

                                 I. DEFINITIONS

     The following terms, as used herein, shall have the following meanings,
whether used in the singular or plural (some terms are defined within a section
in which they are used):

     "Affiliate" means another company, corporation, or partnership in which a
Party directly or indirectly owns at least 50 percent of the outstanding capital
stock or other equity interest, and, in the case of IMPCO, another corporation
which owns more than 50 percent of the capital stock of that Party.

     "Agreement" means this Teaming Agreement, including all Exhibits identified
herein.

     "Background Patents" means all patents, regardless of country or origin or
issue, which are owned or controlled by a Party, that cover an invention
directly related to the Purpose of this Teaming Agreement and which were not
conceived or first reduced to practice in the course of the work performed
pursuant to this Teaming Agreement; provided, however, that in the case of GM
any such patents of its Delphi and Delco Electronics organizations are excluded
for purposes of this Agreement.

                                       2
<PAGE>

     "Background Technology" means technical information owned or controlled by
a Party and directly related to the Purpose of this Teaming Agreement and which
was not conceived or first reduced to practice in the course of the work
performed pursuant to this Teaming Agreement; provided, however, that in the

                      II. FORMATION OF TEAMING ARRANGEMENT

2.1  Agreement To Team; Management Committee
     ---------------------------------------

     Work under this Agreement shall be coordinated between IMPCO and GM by a
Management Committee, made up of three representatives from each Party. Initial
members of the Management Committee are identified in Exhibit 1. Either Party
may change its members assigned to the Management Committee by providing written
notice to the other, provided that (i) no person shall be a member of the
Management Committee who is not an employee of the Party appointing such person
unless the other Party consents thereto, and (ii) each Party shall exercise
reasonable effort to maintain continuity in its assignments. Unless otherwise
agreed by the Parties, the Management Committee shall include at lease one
engineering representative and one procurement representative from each Party.

     Responsibilities of the Management Committee includes identifying projects
appropriate for this Teaming Agreement, and reviewing the progress of ongoing
projects compared to each respective project business plan. The Management
Committee shall approve a business plan and statement of work for each project
hereunder, including identification of which Party is to initiate and carry out
the project, budget and cash needs responsibilities, and allocation of plant,
personnel and other non-cash resources. The Management Committee shall also be
responsible for resolution of any conflicts between the Parties relative to
projects hereunder, and shall follow and benchmark field performance of gaseous
fuel propulsion systems and related components thereof.

                                       4
<PAGE>

     The Management Committee shall meet periodically, but at least once every
three months. Meetings shall be called and coordinated by the respective Program
Managers, who shall jointly prepare an agenda in advance of each meeting. A
quorum for a Management Committee meeting shall consist of two members from each
Party; decisions of the Management Committee shall be by unanimous consent of
members present.

     The Management Committee shall keep minutes of its meetings and the actions
taken by it; such minutes shall be prepared by the Secretary and reviewed by the
Counterpart Secretary of the other Party before distribution. In the initial
year, GM shall appoint the Secretary from its employees on the Management
Committee, and IMPCO shall appoint the Counterpart Secretary from its employees
on the Management Committee. Thereafter, the positions of Secretary and
Counterpart Secretary shall switch to the other Party annually, unless otherwise
agreed by the Management Committee. Members of the Management Committee may
conduct meetings by telephone if both Parties consent; in person meetings shall
rotate through different sites the Management Committee deems relevant to its
business.

2.2  Program Managers
     ----------------

     Each Party shall appoint a Program Manager, who may or may not be a member
of the Management Committee. Such Program Managers shall be the primary
interface on a day to day basis between the Parties. The Program Managers shall
report on their activities to the Management Committee at its meetings, and
prepare the agenda for Management Committee meetings.

                                       5
<PAGE>

     Initial Program Managers are identified in Exhibit 1; either Party may
change its person assigned as Program Manager by providing written notice to the
other, provided that no person shall be a Program Manager who is not an employee
of the Party appointing such person unless the other Party consents thereto.
Separate program managers may be identified for selected projects, as directed
by the Management Committee or provided in contracts for such projects.

2.3  Limitations of Authority
     ------------------------

     Nothing contained in this Agreement, and no action taken or recommended by
the Management committee or the Program Managers, shall be deemed to (I) make
any Party hereto (or any of such Party's employees, agents or representatives)
an employee, agent or representative of the other Party, (ii) confer on any
Party any expressed or implied right, power or authority to enter into any
contract, express or implied, or to incur any obligation or liability on behalf
of the other Party, or (iv) require any Party to take any action which is
contrary to any contract, regulatory or other applicable legal requirement or
standard.

                                      III.

3.1  Supplier Right of First Refusal
     -------------------------------

     IMPCO and GM each agrees to buy from the other any production quantities of
gaseous fuel propulsion systems or related components developed hereunder which
the buyer may require, provided (I) such components are not to be produced by
the buyer, an Affiliate of the buyer, or under any contract commitment which
predates this Agreement, (ii) the seller has demonstrated ability to supply such
components, and (iii) the seller is competitive as to price (including contract
terms), quality and service. If, in the

                                       6
<PAGE>

reasonable opinion of the buyer, one or more such components otherwise meeting
requirements of the immediately preceding sentence is found to not be
competitive in price, quality or service, the buyer, to the extent it is free to
do so, will advise the seller in writing of the area(s) in which another
supplier is more competitive. If, within 5 business days of such notice, the
seller does not agree to sell such component(s) with comparable price, quality
and service, then the buyer may purchase such component(s) from such other
supplier.

     In any instance in which GM contracts with IMPCO to supply any gaseous fuel
propulsion system or related component developed under this Agreement, IMPCO
will not, for a period of two years from the date of GM's commercial
introduction, solicit sales thereof to third parties. If a potential third party
buyer should approach a Party hereto for supply of gaseous fuel propulsion
systems or components utilizing technology developed hereunder during such two
year period, the Party approached shall bring the inquiry to the Management
Committee for review and consideration as appropriate. Among the alternatives
which could be considered in appropriate circumstances is formation of a joint
venture between the Parties to meet third party customer requirements, or
payment of a reasonable royalty by one Party to the other.

3.2  Purchase Orders; Shared Resources
     ---------------------------------

     Any Agreement by one Party to buy, and the other to produce and sell to
such buyer, one or more gaseous fuel propulsion systems or related components
developed hereunder, shall be concluded by way of a purchase order based on such
buyer's then current terms and conditions applicable generally to supply of
goods used in its core businesses, unless otherwise agreed to in a written
amendment to such purchase order or

                                       7
<PAGE>

other written contract document. A copy of those terms and conditions, including
both the pre-printed terms and additional terms applicable to long term purchase
arrangements, appear in Exhibit 2.

     In the event GM should place a vehicle program with IMPCO for installation
of a gaseous fuel propulsion system or related components, such placement shall
fall under applicable provisions of GM's second stage manufacturing policy and
the contract provisions consistent with that policy.

     Consistent with this Agreement and Management Committee direction, the
Parties will work together to develop and share sourcing strategy and
procurement for any joint programs. Pricing for gaseous fuel propulsion systems
and related components between the Parties shall reflect an appropriate
differential from that to third parties reasonably reflective of the joint
efforts hereunder.

3.3  Development Programs
     --------------------

     The Parties will work together to facilitate pre-production consideration
of design for manufacturability and other considerations for efficiency. Each of
the Parties will use its best efforts to work together to develop and improve
car and truck gaseous fuel propulsion systems and related components hereunder.
Except as specifically agreed in advance in writing, each Party shall be
responsible for its own costs associated with such cooperation.

     so that the disclosing Party may seek a protective order or take other
     appropriate action, and the receiving Party shall furnish only that portion
     of Proprietary Information which is required.

4.2  Nothing in this Agreement shall be interpreted as precluding an employee of
one of the Parties to this Agreement from making use of his or her general
knowledge in conjunction with other projects being performed on behalf of his or
her employer, even if such knowledge has been furthered by him or her having had
access to the Proprietary Information exchanged under this Agreement.

4.3  Proprietary Information disclosed by a Party shall remain the property of

    provided by it for inclusion in the registration statement. Questor will
    also enter into a standard lock-up agreement with the underwriters on the
    same form provided to other affiliates and officers and directors that is
    consistent with the terms of this agreement.

2.  Questor's shares will be the first shares included in the Primary Offering
    (and conversely, will be the last shares cut-back).

3.  In addition to the Company's obligations under paragraph 1, if Questor holds
    more than 75,000 shares of the Company's Common Stock, Questor may demand in
    writing that the Company register some or all of the shares that it holds on
    Form S-3. Questor may exercise its right to demand registration at any time
    on or after the earliest of (i) thirty days following the effective date of
    the Primary Offering or (ii) the date on which the Lead Bank advises the
    Company that it will not be proceeding as lead manager with respect to the
    Primary Offering or (iii) July 31, 2000. The written demand shall state the
    number of shares that Questor desires the Company to register. If the
    Primary Offering does not occur before July 31, 2000, Questor shall have the
    right to exercise a demand on two occasions, otherwise Questor shall have
    the right to exercise a demand on only one occasion. Upon receipt of a
    demand meeting the foregoing requirements, the Company at its expense will
    promptly prepare, file and use reasonable efforts to have declared effective
    a stand-alone S-3 registration statement covering all shares of the
    Company's Common stock that Questor has stated it wishes to have registered
    in such registration. The Company will use its best efforts to maintain the
    effectiveness of any registration statement filed in response to Questor's
    demand until the earlier of the sale of all of the shares covered by the
    registration statement or the expiration of two years from the effective
    date of the registration statement (three years if Questor is not able to
    sell all of the First Tranche in the Company's Primary offering by
<PAGE>

    July 31, 2000). Each such registration will provide for a broad manner of
    distribution (e.g., block trades, ordinary broker transactions, privately
    negotiated sales and, if Questor provides the necessary information,
    underwritten offerings), and the Company and Questor will sign a
    registration rights agreement providing for the Company's cooperation with
    any secondary offering by Questor (including indemnification of the selling
    stockholders and underwriters by the Company) and other customary terms.

4.  Questor will not sell publicly (except under the Primary Offering), without
    the consent of the Lead Bank, any shares of the Company's Common Stock
    during a period (the "Interim Period") beginning on the date of this
    agreement and ending on the earliest to occur of (i) the consummation of the
    Primary Offering, (ii) July 31, 2000, if no Primary Offering that includes
    the First Tranche has been consummated by July 31, 2000, and (iii) the date
    on which the Lead Bank advises the Company that it will not be proceeding as
    lead manager with respect to the Primary Offering.

5.  If a Primary Offering that includes all of the First Tranche is consummated
    by July 31, 2000, Questor will not sell publicly (except under the Primary
    Offering), without the prior written consent of the Lead Bank any shares of
    the Company's Common Stock for a period beginning on the day prior to the
    consummation of the Primary Offering and ending 135 days after the effective
    date of the Primary Offering. The 135 day period specified in the preceding
    sentence shall be shortened to any shorter period that applies to any
    officer, director or other person who is an affiliate by virtue of share
    ownership on the date of this agreement; provided, however, this provision
    shall not apply to (i) case by case exceptions made by the Lead Bank or (ii)
    up to 1000 shares for each person who becomes an officer after the date of
    this agreement or who own no shares on the date of this agreement who in
    either case receives the shares by virtue of purchases upon exercise of
    options or similar rights.

6.  Persons designated by Questor on the Company's Board of Directors will
    resign from the Board prior to the effective date of the Primary Offering.
    If the directors have resigned and the Primary Offering does not occur by
    July 31, 2000 or the Primary Offering does occur before that date, but on
    the first anniversary of the date of this agreement Questor continues to
    hold at least 500,000 shares of the Company's Common Stock, then upon
    receipt of a written request to appoint or elect a person designated by
    Questor to become a member of the Company's Board of Directors, naming a
    person who is willing to become a director, the Company will take all action
    necessary and within its power and will use all reasonable good faith
    efforts to cause such person to be appointed or elected to the Board.

7.  It is understood by the parties that this agreement will be disclosed in
    connection with one or more filings with the Securities and Exchange
    Commission.
