ITEM 1--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 $65 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.

                                       2
<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 prohibiting certain vehicles from
driving on designated days of the week. However, vehicles running on propane or
natural gas may apply for an exemption allowing them to 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 generally 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 power generation markets. While we believe that our
gaseous fuel storage, fuel delivery and electronic control systems and products
will eventually be applicable to all three of these markets, we anticipate
initially focusing 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

                                       3
<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 fuel storage, fuel delivery and
electronic controls.

Alternative Fuel and Fuel Cell Markets

   The markets for transportation, material handling, industrial engine and
fuel cell applications, and power generation markets for fuel cell and
alternative fuel engine applications are large and 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, Hyundai, 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 focusing primarily
on the development and integration of fuel storage, fuel delivery and
electronic control systems in fuel cell and gaseous fuel applications. We have
no current plans to manufacture fuel cells or reformers.

Competitive Advantages

   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, our substantial financial commitment to research and
development and our 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 system technology industry. Our significant
investment of more than $65 million in research and development over the past
seven 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.

   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

                                       4
<PAGE>

adapted to apply to a broad range of applications. We have also concentrated
efforts on extensive testing and validation of our new advanced fuel technology
products which focus upon safety and durability. In 1995, we began development
of products for fuel cell applications in our target markets. Our new TriShield
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, 1999 and 2000,
sales to General Motors represented 27.8% and 16.0% of our revenues,
respectively. In addition, we have longstanding relationships with many
domestic and international OEMs, including BMW, Caterpillar, Clark, Cummins,
Daewoo, Detroit Diesel, Ford Australia, Hyster/Yale/Sumitomo, Isuzu, Komatsu,
Mazda, Mitsubishi, Nissan, ONAN, Perkins, 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 Mexican government to develop advanced fuel solutions for public
transportation, government and taxi fleets. The government of Mexico State
recently selected us as the preferred vendor for the conversion of over 4,000
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.

                                       5
<PAGE>

   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 is expected to 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
and Thiokol Propulsion, 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 technology required
for fuel cells. We believe our core technologies can 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.

   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. We will capitalize on these opportunities 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 Mexican government.
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.

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, Ford Australia, Hyster/Yale/Sumitomo, Isuzu,
Komatsu, Mazda, Mitsubishi, Nissan, ONAN, Perkins, Toyota and Volvo. We are
working with a number of these customers to address their fuel storage, fuel
delivery and electronic control systems requirements as they integrate fuel
cells into their business strategies.

                                       6
<PAGE>

   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 alternative 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
systems to optimize their operational performance and efficiency using the
alternative fuels.

   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 is ISO 9001 certified. We have
not experienced and do not expect to experience any significant difficulty in

of gasoline in May 2000, 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.

   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

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 delivery and electronic
control systems for the alternative fuel and fuel cell markets. While we
recognize that there are several competitors 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 our target markets for use in all end user 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 fuel to 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.

   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

                                       15
<PAGE>

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 trademarks of IMPCO Technologies, Inc. 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 April 30, 2000, our backlog for our products was approximately $21.5
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.

   We also lease nominal amounts of office space in Japan, Germany, France and
Australia.

   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.

   The Company has never paid dividends on its common stock. 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.

Overview

   We are a global supplier of fuel storage, fuel delivery 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 fuel storage, fuel
delivery 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
segment. The Automotive OEM division generates revenues through the sale of
fuel storage, fuel delivery and electronic control systems to OEMs, primarily
General Motors and the installation of our products into OEM vehicles. This
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 segment includes sales by our
subsidiaries in Australia, Europe, Japan and Mexico which provides distribution
for our products, predominantly from our Gaseous Fuel Products division, as
well as, 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.

   We expense all research and development when 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.

   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 and the United States and from formation of a
European based joint venture. We have accounted for each of these acquisitions
under the purchase method of accounting.

</TABLE>

   Automotive OEM Division. Net revenues decreased $2.1 million or 8.6% from
$24.4 million in fiscal 1999 to $22.3 million in fiscal year 2000.

   Product sales for this division decreased $400,000 or 3.0% from $13.5
million in fiscal year 1999 to $13.1 million in fiscal year 2000. This
decrease was primarily due to a decline in unit sales to General Motors.
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 General Motors medium duty trucks equipped with dedicated

                                      21
<PAGE>

liquid propane gas kits provided under the Teaming Agreement with General
Motors. 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 $1.7 million or 15.7% from
$11.0 million in fiscal year 1999 to $9.3 million in fiscal year 2000. This
decrease was primarily due to lower contract levels which reflect efficiencies
that result from our ability to transfer knowledge between prior model year and
current model year contracts. We anticipate, based on new contracts negotiated
with General Motors and expected levels of contract completion on new
government agency contracts with the Southern California Air Quality Management
District, that contract revenue in fiscal year 2001 will be comparable to
levels experienced during fiscal year 2000.

   Operating losses in the division increased $1.4 million from $27,000 in
fiscal year 1999 to $1.5 million in fiscal year 2000. This increase 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 for this division
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. In fiscal year 2000,
expense directly related to customer funded product application development
work was approximately $8.0 million as compared to $6.1 million in fiscal year
1999. We anticipate product application development costs will be higher in
fiscal year 2001 as new products are being commercialized and integrated under
the new application development contracts.

   Gross margins on General Motors product sales were higher in fiscal year
2000 as compared to fiscal year 1999, primarily due to lower material costs as
a result of engineering design efficiencies and reduced overhead costs. We
anticipate higher gross margins on products in fiscal year 2001, primarily due
to additional engineering design efficiencies and reduced overhead costs.
Additionally, we anticipate comparable operating losses in this division in
fiscal year 2001, primarily due to higher product sales and gross profits being
offset by higher customer and company funded application development work.

   Gaseous Fuel Products Division. Net revenues in this division increased
$24.2 million or 46.0% from $52.6 million in fiscal year 1999 to $76.8 million
in fiscal year 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 2001
will be higher than fiscal year 2000, primarily due to the continued growth of
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, increased small engine
sales and our marketing efforts to expand market share.

   Operating income in this division increased approximately $5.2 million or
36.0% from $14.3 million in fiscal year 1999 to $19.5 million in fiscal year
2000. 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 and
higher product development expenses related to developing next generation
fuel/engine management systems for the material handling market. We anticipate
that this division's operating income will be higher in fiscal year 2001 as a
result of higher revenues and gross profit associated with increased volumes
partially offset by increased product development expenses. 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 segment increased by
approximately $8.8 million or 10.8% from $21.2 million in fiscal year 1999 to
$30.0 million in fiscal year 2000. This increase was primarily a result of
increased revenues in Mexico from $2.7 million in fiscal year 1999 to $6.7
million in fiscal year 2000 and the March 1999 acquisition of IMPCO Japan,
which resulted in increased revenues of approximately $2.9 million in fiscal
year 2000. In fiscal year 2000, revenues for our International Operations
segment would have increased an additional $800,000, if not for the
strengthening of the U.S. Dollar. A strong U.S. Dollar has a negative effect on
the conversion of foreign currency denominated sales. We anticipate that
revenues for this segment during fiscal year 2001 will be higher than fiscal
year 2000 as a result of higher motor vehicle sales in Mexico and market growth
in each of the countries serviced by our International Operations segment. 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.

   Operating income for this division increased $1.1 million or 74.4% from $1.5
million in fiscal year 1999 to $2.6 million in fiscal year 2000. This increase
was primarily due to the addition of our Japan operations and higher
profitability of our European operations. We believe that operating income
levels in our International Operations segment will be higher in fiscal year
2001 than in the current year due to anticipated higher revenues and gross
profits at each of our International Operations.

   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 $1.5 million or 27.7% from $5.5 million
in fiscal year 1999 to $7.0 million in fiscal year 2000. The increase in
corporate expenses was primarily due to the incremental costs associated with
the evaluation of the unsoliciated tender offer issued to us by BERU, AG, 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 2001
will be lower than levels experienced during fiscal year 2000.

   Corporate Research and Development. Corporate research and development is a
component of our research and development expense and relates to 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 $4.0 million or 129.0% from $3.1 million in
fiscal year 1999 to $7.1 million in fiscal year 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 2001 will be significantly higher
than in fiscal year 2000. The additional expenditures will be partially offset
by new government agency contracts such as the contract with the Department of
Energy. We anticipate that the higher level of corporate research and
development expenditures will have a significant negative effect on our
profitability in fiscal year 2001.

   Interest Expense. Interest expense increased $272,000 or 23.3% from $1.2
million in fiscal year 1999 to $1.4 million in fiscal year 2000. This increase
was attributable to additional borrowings partially offset by lower interest
rates on our current credit facility with Bank of America.

   Provision For Income Taxes. The estimated effective annual tax rate of 24.2%
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
effective tax rate represents the federal statutory income tax rate, state
income taxes

                                       23
<PAGE>

and foreign income taxes reduced by research and development tax credits. At
April 30, 2000, net deferred tax assets were approximately $4.2 million while
the net deferred tax liabilities were $745,000. 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.

   Net revenue increased $15.7 million or 22.1% from $71.1 million in fiscal
year 1998 to $86.8 million in fiscal year 1999. The Automotive OEM division
accounted for $12.1 million of this increase, of which $9.7 million resulted
from increased OEM motor vehicle product sales. Contract revenues, primarily
from the General Motors Teaming Agreement, increased $2.4 million. Product
sales from the Gaseous Fuel Products division increased by approximately $4.4
million or 9.0% compared to the prior fiscal year. The following table sets

   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 primarily 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 sales of biofuel compressed natural gas fuel
systems for mid-size automobiles and sales of pick-up trucks and dedicated
liquid 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 bi-fuel compressed natural gas fuel systems for General
Motors pick-up trucks 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 were primarily due to 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, this 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 addition of the
Industrial Engine Systems business in fiscal year 1999, 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

                                       25
<PAGE>

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 $271,000 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 primarily 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

                                       26
<PAGE>

year 1999, our deferred tax assets 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 used all net operating loss carryforwards at 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 to 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. We
cannot assure you that such additional sources of financing will be available
on acceptable terms, if at all.

   The ratio of current assets to current liabilities was 3.1:1 at April 30,
2000 and 3.1:1 at April 30, 1999. During fiscal year 2000, our total working
capital increased by approximately $14.4 million to $49.6 million at April 30,
2000. Net cash used in operating activities was $6.6 million in fiscal year
2000 as compared to net cash provided by operating activities of $440,000 for
fiscal year 1999. The increase in cash used in operating activities during the
current period resulted primarily from an increase in inventory and accounts
receivable. The increase in inventory was primarily to support increased sales
volume across our operating segments. The increase in accounts receivable is
primarily due to the increased international and OEM billings and an increase
of $2.8 million in earned, but not yet billed, contract revenues classified as
accounts receivable.

   Net cash used in investing activities in fiscal year 2000 was approximately
$4.0 million, a decrease of approximately $551,000 from fiscal year 1999. 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, the
previous year's first quarter purchase of the remaining 49.0% interest in IMPCO
Europe, which resulted in a net use of cash of approximately $692,000,
partially offset by the proceeds from the sale of 49.0% interest in subsidiary.
Investing activities for fiscal year 1999 primarily included capital
expenditures for dies, molds and patterns, machinery and equipment, and the
investment in IMPCO Fuel Systems.

   Net cash provided by financing activities for fiscal year 2000 was
approximately $11.9 million. For the current fiscal year, we increased our
borrowing under our operating lines of credit by approximately $14.3 million,
primarily for working capital. During the same period, we paid approximately
$3.5 million on our term loans and capital leases.

   We have a $22.0 million revolving line of credit, $3.0 million revolving
line of credit for IMPCO Mexicano, and $5.0 million non-revolving line of
credit for future capital expenditures with Bank of America. At April 30, 2000,
approximately $15.6 million, $851,000 and $2.7 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 capital lease facility expires 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 $1.2 million at April 30, 2000) credit facility with Mees
Pierson, a financial institution in the Netherlands. At April 30, 2000, there
was no outstanding balance under this credit facility. Our subsidiary in Japan
has a revolving term loan facility with the Hong Kong and Shanghai Banking
Corporation Ltd., Osaka Branch. At April 30, 2000, the fully dispersed loan
balance of (Yen)60,000,000 (US $555,000) was outstanding.

   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 April 30, 2000, we had no forward
currency contracts. 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
generally linked to a specific debt instrument. At April 30, 2000, we had
approximately $3.6 million in fixed interest rate agreements. Loans totaling
$2.4 million at April 30, 2000 had a weighted-average fixed interest rate of
7.76%. Absent these fixed rate agreements, the weighted-average variable rate
for this debt at April 30, 2000 would have been 8.02%. Capital leases totaling
$1.2 million had a weighted-average fixed interest rate of 8.30%. Absent these
fixed rate agreements, the weighted-average variable rate for these leases at
April 30, 2000 would have been 8.75%. At April 30, 2000, the fair value of
interest rate swap agreements was $45,000.

   Debt Obligations. The following table summarizes our debt obligations at
April 30, 2000. 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, 2000.

Acquisitions

   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
50.0% ownership interest in Gas Parts. In March 2000, one of our subsidiaries,
IMPCO Technologies, Pty Ltd and LPM Corporation Pty Ltd, a corporation
incorporated under the laws of the state of New South Wales, Australia,
established IMPCO Fuel Systems, a joint venure to service this geographical
market. IMPCO Technologies, Pty Ltd has a 51% ownership interest in IMPCO Fuel
Systems and paid $300,000 in the purchase of goodwill of LPM's gaseous fuel
equipment business and $110,000 in certain assets, inventory and equipment of
LPM. The consolidated revenues of our Australian subsidiary, our Australian
joint venture and IMPCO SA, which we collectively refer to as IMPCO Australia,
totaled approximately $6.9 million in fiscal year 1998, $5.4 million in fiscal
year 1999 and $6.3 million in fiscal year 2000.

   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, Grupo I.M.P.C.O.
Mexicano, S. de R.L. de C.V., which we refer to as IMPCO Mexicano. Our Mexican
subsidiary had revenues of approximately $823,000 for five months of operations
in fiscal year 1998, $2.7 million in fiscal year 1999 and $6.7 million in
fiscal year 2000.

   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. In January 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.
("IMPCO Europe") Revenues of this majority owned subsidiary were approximately
$11.6 million in fiscal year 1998, $12.9 million in fiscal year 1999 and $13.9
million in fiscal year 2000.

   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 and $16.6 million
in fiscal year 2000.

   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.

                                       29

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 assets. We operate the new company as
Impco Japan KK. Revenues for the one month of operation in fiscal year 1999
were approximately $178,000 and $3.1 million in fiscal year 2000.

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."
This 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 plan to implement any changes as we deem to be appropriate.

ADDITIONAL FACTORS THAT MAY AFFECT STOCK PRICE

   The preceding discussion contains forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended, and Section
21E of the Securities Exchange Act of 1934, as amended. The Company faces a
number of risks and uncertainties which could cause actual results or events to
differ materially from those contained in any forward-looking statement.
Factors that could cause or contribute to such differences include, but are not
limited to, the following:

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

   We do not know when or whether we will successfully complete the research
and development of commercially viable fuel storage, fuel delivery or
electronic 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 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 storage, fuel delivery and electronic 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 and could
negatively impact our overall profitability. 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 Division's 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, 2000 for our
Automotive OEM division and 16.0% 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

                                       31
<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.

   Additionally, our contract provides for a non-exclusive right of first
refusal to General Motors on jointly developed products. 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.

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

   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, 2000 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

                                       32
<PAGE>

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.

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.

                                       33
<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.

                                       34
<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 domestic and foreign patents outstanding which
will expire between November 2001 and October 2018. We also have one patent
application outstanding in our fuel cell enabling technology. We do not know
whether 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 fuel storage 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;

                                       35
<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.

   We 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 our products used
in 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, which 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.

                                       36
<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 our best interests or the best interests of our stockholders.

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

   Substantial sales of our common stock, including shares issued upon exercise
of our outstanding options in the public market following the offering of
additional shares of our common stock under a Registration Statement on
Form S-3 filed with the Securities and Exchange Commission on April 7, 2000 and
amended on June 14, 2000, 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 such offering, we will have
10,204,807 shares of common stock outstanding. Of these shares, the 2,500,000
shares sold in this offering

                                       37
<PAGE>

will be freely tradeable. Of the remaining 7,704,807 shares, 4,831,080 shares
which are currently freely tradeable will remain freely tradeable and 2,946,291
shares will be subject to 135 day lock-up agreements. In addition, up to
1,313,931 shares issuable upon the exercise of options outstanding as of May
31, 2000 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.

                         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, 1999 and 2000, and the related consolidated
statements of income, stockholders' equity and cash flows for each of the three
years in the period ended April 30, 2000. Our audits also included the
financial statement schedule listed in the Index at Item 14(a). These financial
statements and schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
schedule based on our audits.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

   In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of IMPCO Technologies, Inc. at April 30, 1999 and 2000, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended April 30, 2000, in conformity with accounting principles generally
accepted in the United States. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects the
information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   (a) Basis of presentation and description of the business--The consolidated
financial statements of IMPCO Technologies, Inc. ("IMPCO" or the "Company")
include the accounts of the Company and its majority owned subsidiary IMPCO-
BERU Technologies B.V. ("IMPCO BV"), its majority owned subsidiary Grupo
I.M.P.C.O. Mexicano, S. de R.L. de C.V. ("IMPCO Mexicano") 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) 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.

   (c) 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.

   (d) 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.

   (e) 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.

   (f) 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.

   (g) Revenue recognition--Revenue is recognized on product sales when goods
are shipped in accordance with the Company's shipping terms. 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. 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 evaluated the effect of SAB
101, which did not result in any material change to their revenue recognition
policies.

   (h) Minority interests in subsidiaries--The balance sheet amounts in
minority interest at April 30, 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, 49% of the equity held by the single
minority stockholder in IMPCO SA, a subsidiary of IMPCO Pty, and 49% of the
equity held by the single minority stockholder in IMPCO Fuel Systems. Minority
interests represents the minority stockholder's proportionate share of equity
in those subsidiaries.

                                      F-8
<PAGE>

   (i) 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.

   (j) 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).

   (k) 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.

   (l) 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.

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

   (n) 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 foreign
currency commitment, are included in the results of operations and cash flows
as incurred.

   (o) 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, 2000 off balance sheet derivative financial instruments included
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. No such contracts
were outstanding at April 30, 2000.

   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 principal.

                                      F-9

Accounting Pronouncements

   The Financial Accounting Standards Board has issued certain Statements of
Financial Accounting Standards (SFAS) that are applicable to the Company. 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 (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.

   The Financial Accounting Standards Board has also 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 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 its plans as deemed
appropriate.

 (a) Bank of America NT&SA

   At April 30, 2000 the Company has a credit facility with Bank of America
NT&SA, as amended on June 13, 2000. This facility includes a $22 million
revolving line of credit (due August 31, 2001), a $5,000,000 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. Additionally, 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.

   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
$38,239,000 at April 30, 2000. Details about each of the components of the
Company's credit facility at April 30, 2000 follows.

   Revolving Line of Credit. The $22 million 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 April 30, 2000, the
outstanding line of credit balance was $15,550,000, which was subject to the
offshore rate at a weighted average of 7.51%.

   The line of credit 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 $22,000,000. At April 30, 2000, a standby
letter of credit totaling $375,000 was outstanding.

   Mexican peso line of credit. The Mexican peso line of credit at April 30,
2000 totaled $851,000 and was subject to a rate based on the Bank of America
Mexico (BAMSA) cost of funds plus 1.50% or 18.50%.

                                      F-12

   Term Loans for Acquisitions. All term loans bear interest, payable on a
monthly basis, at the Bank's reference rate and mature through fiscal 2003. 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% or 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. The Company has entered into two interest rate swap agreements
with Bank of America NT&SA to fix the interest rate on certain facilities. At
April 30, 2000, the total outstanding balance was approximately $3,028,000,
which bore a weighted average interest rate of 7.73%.

   Capital Lease and Expenditure Facilities. The company has a capital lease
facility and a capital expenditure line of credit. At April 30, 2000 no further
borrowings were available under the capital lease. At April 30, 2000, all draws
under the capital lease facility were subject to the variable rate of interest
based upon the three month LIBOR plus a spread. 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 for the various fundings. At April 30, 2000,
approximately $2,168,000 was outstanding under this facility, of which
approximately $398,000 was fixed at 8.50% and approximately $802,000 was fixed
at 8.20%. The remaining balance of approximately $968,000 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 (8.5% as of April 30, 2000). If the
Company exercises an early termination option before the scheduled expiration
date of a capital lease, a termination charge will be assessed based on a
sliding percentage (not to exceed 3%) of the balance on the lease at time of
termination.

   The Company has a $5,000,000 non-revolving capital expenditure line of
credit. This line of credit bears interest at the Bank's reference rate or an
optional offshore rate. The line matures on August 31, 2000 at which time the
Company will repay principal in 20 successive quarterly installments, starting
on the last day of the third month after funding. The line may be prepaid, in
whole or in part, at any time. At April 30, 2000, the total outstanding balance
was approximately $2,675,000, bearing interest at 7.8%.

   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 debt. The cost of the facility
is 1.00% per annum of the amount outstanding. On April 30, 2000, the amount
outstanding under the standby letter of credit was $1,737,000.

   IMPCO BV Term Loan. The Company has a credit facility with Bank of America
NT&SA through its Amsterdam branch. which bears interest, payable on a monthly
basis, at the Euro Interbank Offered Rate for the corresponding period of the
advance, plus 1.50%. 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, 2000,
the outstanding balance of fl.2,520,000 (US$1,043,000) bore an interest rate of
5.60%.

   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, 2000, the Company was in compliance with all covenants.

 (b) 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, 2000, the interest
rate was 5.25% and there was no outstanding balance.

 (c) 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% and matures in fiscal year 2004. 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, 2000, the outstanding loan balance of
(Yen)128,000,000 (US$1,183,000) bore an interest rate of 1.737%.

   Line of Credit. On March 29, 1999, IMPCO Japan secured a (Yen)60,000,000
(US$559,000) revolving line of credit facility with the Hong Kong and Shanghai
Banking Corporation Ltd., Osaka Branch. This facility bears interest, payable
on a quarterly basis, at the Euroyen London Interbank Offer Rate plus 1.60% and
matures in fiscal year 2001. 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, 2000, the outstanding loan balance of (Yen)60,000,000 (US$555,000) bore a
weighted average interest rate of 1.726%. It is management's intent to renew
the line of credit for an uninterrupted period extending beyond one year from
the balance sheet date.

   Annual maturities of long-term debt, excluding capital leases (see Note 6)
for the five years subsequent to May 1, 2000 are as follows: 2001--$3,061,000;
2002--$18,378,000; 2003--$1,812,000; 2004--$831,000; 2005--$535,000; and
thereafter--$268,000.

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.

   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, 2000, the Company had
no forward currency contracts outstanding.

   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, 2000,
the Company had approximately $3.6 million in fixed interest rate agreements
and loans and leases secured under these fixed interest rate agreements had a
weighted-average fixed interest rate of 7.94%. Absent these fixed rate

                                      F-14
<PAGE>

agreements, the weighted-average variable rate for this debt would have been
8.26%. The fair value of these instruments is based on estimated current
settlement cost. At April 30, 2000, the fair value of interest rate swap
agreements was approximately $45,000.

   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, 2000,
the fair value of the Company's long-term debt approximated carrying value.

   The current federal provision for income taxes for fiscal years 1999 and
2000 was reduced by using research and development credits of approximately
$502,000 and $292,000, respectively. The current state provision for income
taxes for fiscal years 1999 and 2000 was reduced by using research and
development and investment credits of approximately $516,000 and $191,000,
respectively.

   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 rates.

   Total rental expense under the operating leases for fiscal years ended April
30, 1998, 1999, and 2000 was approximately $1,127,000, $1,281,000, and
$1,846,000, respectively. These leases are non-cancelable and certain leases
have renewal options.

   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, 1999, and 2000, approximately
$2,625,000, $2,946,000 and $2,168,000 was outstanding under the capital lease
facility, respectively. At April 30, 1999, the gross and net assets acquired
under the capital lease facility were approximately $5,224,000 and $2,565,000,
respectively. At April 30, 2000, the gross and net assets acquired under the
capital lease facility were approximately $4,581,000 and $2,091,000,
respectively.

 (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
employment 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 3.0% of compensation. Approximately 66% of
eligible employees were enrolled in the 401(k) plan at April 30, 2000. Employer
contributions approximated $98,000, $122,000, and $482,000 for fiscal years
ended 1998, 1999, and 2000, respectively.

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) Stockholder Protection Rights Agreement

   On June 30, 1999, the Company's Board of Director's adopted a Stockholder
Protection Rights Agreement and declared a dividend of one right on each
outstanding share of IMPCO common stock. Each right entitles the holder to
purchase one share of common stock. The dividend was paid on July 26, 1999 to
stockholders of record on July 12, 1999.

 (c) 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, 2000, there were 47,895 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%

                                      F-20
<PAGE>

of total consolidated revenues, respectively, and contract revenue accounted
for approximately 13% of consolidated revenues. During fiscal year 2000, the
IMPCO BV, IMPCO Pty, Grupo IMPCO Mexicano and IMPCO Japan subsidiaries
accounted for approximately 12%, 6%, 6% and less than 3% of total consolidated
revenues, respectively, and contract revenue accounted for approximately 8% of
consolidated revenues. During fiscal year 1998, 1999, and 2000, General Motors
Corporation, and customers associated with the General Motors program,
accounted for approximately 15%, 28% and 16%, respectively, 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 products into
OEM vehicles. The division also generates contract revenue by providing
engineering design and support to the OEMs so that fuel systems 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, as well as 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.

                                     F-24
<PAGE>

   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.
