     In December 1997, the Company purchased from the bankruptcy trustee of 
EDO Canada, Ltd. certain development, testing, quality control and 
manufacturing equipment used for the manufacture of storage tanks for 
compressed natural gas. The US$790,000 purchase price was paid in cash.


PRODUCTS AND MARKETS

     The Company's products include fuel management systems and components, 
including electronic fuel control processors, carburetors, converters or 
regulators, fuel lock-offs, repair kits or replacement parts and other sundry 
devices.  The Company's products, sold for aftermarket conversions and as 
original equipment, are used in a variety of motor vehicles, forklifts and 
small portable to large stationary engines.  Worldwide, the products are 
marketed through distributors and original equipment manufacturers (OEM) 
under the brand names IMPCO (registered trademark), BEAM(registered 
trademark), GARRETSON(registered trademark), J&S Carburetion (registered 
trademark), and Algas.   Ease of installation, consistent performance, high 
quality and safety are attributes of the Company's products.

     The Company's fuel management systems are designed to offer several 
levels of technology to meet customer needs.  The Adaptive Digital Processor 
(ADP) uses advanced electronic technology to learn and store key operating 
characteristics of the specific vehicle.  The ADP enhancer complements the 
ADP with diagnostics and spark timing modules.  The Company's Advanced Clean 
Fuels Technology (ACFT) uses mass sensing hot wire anemometry to calculate 
the engine's air/fuel mixture.  The Company's Heavy Duty Advance Fuel 
Electronics (HD-AFE) uses patented hot wire anemometry mass sensing of both 
fuel and air to precisely control lean burn combustion in heavy duty engines 
utilized in trucks and mass transit vehicles to maximize performance at 
reduced emissions.  During engine operation, an on-board computer adjusts the 
mixture to achieve optimum results in engine performance to reduce emissions. 
The Company is also developing a fuel injection system for ultra low emission 
vehicles.  These injectors are designed for vaporized natural gas or 
vaporized propane for use in the latest engine technologies.

     The Company's carburetors are designed for use in 5 to 5,000 horsepower 
engines.  The Company's liquid propane gas (LPG) converter is a two stage 
regulator and vaporizer that regulates the amount of fuel entering the 
carburetor and then transforms the fuel from a pressurized liquid state to a 
gaseous vapor by exposing the fuel to near atmospheric pressure.  The 
Company's vacuum and electro- mechanical fuel lock-off devices stop the flow 
of fuel when engines stop running.  The vacuum fuel lock-off has been a 
popular product with OEM's due to its safety characteristics.

     During fiscal year 1998, sales of carburetors represented approximately 
30% of consolidated product sales, converters approximately 21%, fuel 
lock-offs approximately 7%, repair kits approximately 17%, electronic control 
systems approximately 7%, and other products and sundry devices approximately 
18%.  The product sales mix during fiscal year 1998 was substantially the 
same as during the prior two fiscal years.

     The Company's products are sold worldwide to distributors and OEMs and 
as aftermarket components and/or retrofit systems.  In fiscal year 1998 sales 
in the United States and Canada represented 57% of the Company's consolidated 
sales.  Sales by region are shown below:

</TABLE>

     During fiscal year 1998, sales to distributors accounted for 
approximately 55% of consolidated product sales, sales to OEM customers 
accounted for approximately 39% and system conversions accounted for 
approximately 6% of consolidated product sales.

     Distributors primarily service the aftermarket conversion business and 
small-volume OEMs, and are generally specialized and privately-owned 
enterprises.  Many domestic distributors have been customers of IMPCO for 
more than 30 years, and most export distributors have been customers for more 
than 20 years.

     Most OEM customers are large engine, vehicle, and forklift manufacturers 
such as Caterpillar Inc., Clark Material Handling Co., Ford Motor Company, 
Generac, General Motors Corporation, Kohler Company, Mitsubishi Caterpillar 
Forklift America, Inc., NACCO Material Handling Group, Onan Corporation, 
Toyota Industrial Equipment Mfg. Inc. and the Waukesha Engine Division of 
Dresser Industries, Inc.

     The Company's older products use vacuum and mechanical controls to 
regulate engine air/fuel ratios.  Motor vehicle carburetors, as well as some 
ancillary devices, often are mechanical and operate independent of other 
engine functions. In recent years in more industrially advanced countries, 
electronically controlled devices have replaced some vacuum actuated 
mechanical devices to improve the engine performance and to more tightly 
control the emissions from internal combustion engines. The Company has 
addressed this change by introducing new electronic devices designed for 
gaseous fuels that interface with the OEM electronics.

     To remain competitive, the Company continues to improve its older 
products and is developing new products. The Company upgraded its ACFT 
gaseous fuel management system that is based on its mass-sensing technology 
and proprietary software.  ACFT is designed to manage air/fuel ratios to 
achieve optimum air/fuel mixture and other engine functions. The Company is 
enhancing its on-board computer utilizing the vehicle-specific software 
required for the AFE product, a mass-sensor and the necessary hardware for a 
variety of vehicle types including pickup trucks, vans and passenger cars. 
The Company is focusing its ACFT marketing efforts on OEMs. The Company is 
also developing improved technologies including injectors, high and low 
pressure regulators, on-board diagnostics, high performance 32-bit engine 
control modules, fuel lockoffs and related components. The Company believes 
that it will continue to satisfy the differing engine and emission control 
approaches being used on engines in its domestic and foreign markets.

MARKET AND REGULATORY ENVIRONMENT

     The Company's worldwide market is influenced by environmental laws which 
regulate emission standards and energy laws which strive for energy 
independence.  In addition, there are certain economic advantages to using 
alternate gaseous fuels in many countries. Legislation has provided 
incentives and programs to promote and develop infrastructures for 
alternative fueled vehicles, some requiring fleet vehicle owners to phase in 
alternative fueled vehicles and imposed penalties upon failure to meet 
standards and guidelines.

     In the United States, the Federal Energy Policy Act of 1992 mandates 
that 75% of the light duty vehicles acquired by the federal, state and 
municipal governments by fiscal 2002, and thereafter, be alternative fueled 
vehicles, and non-government fleet operators of 20 or more vehicles will be 
required to include at least 20% alternative fueled light duty vehicles in 
their total vehicle purchases by fiscal 2002.  Beginning 2006 and thereafter, 
70% of the vehicles acquired by fleet operators of 20 or more must be 
alternative fueled vehicles.

     Companies that manufacture retrofit systems for use in California are 
required to comply with requirements under Title XIII, which require that a 
certain percentage of retrofit conversions be certified, inspected, carry a 
product warranty and comply with new emission standards.  For vehicle model 
year 1998 and 1999, the Company will be required to certify all of its 
retrofit engine families.  Manufacturers are also required to conduct 100,000 
mile durability tests and comply with in-service emission standards.  The 
Environmental Protection Agency has adopted similar requirements for the 
entire United States beginning in 2002.  

     Several other states have adopted similar regulations and mandates which 
are expected to increase the demand for alternative fuels.  These include 
Arizona, Arkansas, Colorado, Connecticut, Florida, Georgia, Hawaii, Iowa, 
Kansas, Louisiana, Massachusetts, Missouri, New Hampshire, New Mexico, New 
York, Oklahoma, Oregon, Texas, Utah, Virginia, Washington and West Virginia.  
In addition, legislation to foster energy independence and/or reduce 
pollution is spurning growth in the use of gaseous fuels in countries such as 
Australia, Mexico, Chile, China, Netherlands, Taiwan, Turkey and Venezuela.

STRATEGIC MARKETING PLAN

     The Company's goal is to retain its position as one of the world's 
leading suppliers of engine components and systems that allow internal 
combustion engines to operate on gaseous fuels.  A key element of the 
Company's steady growth has been the diversity of markets that its products 
serve.  The increasing worldwide demand for gaseous alternative fuel 
management products and systems for motor vehicle uses, material handling 
equipment, and industrial and heavy duty mobile engines, provides the Company 
with a broad market foundation and eliminates dependency on a single market 
segment.  The Company's two largest markets, motor vehicle (primarily fleet 
vehicles) and material handling (primarily forklifts), accounted for 
approximately 83% of the Company's consolidated product sales in the last 
fiscal year.  See "Products and Markets." Of these two markets, the motor 
vehicle market is believed to have the greatest potential for significant 
growth.  The Company anticipates that this growth will result from worldwide 
governmental regulations imposing more stringent emission standards to 
achieve energy independence.  See "Market and Regulatory Environment."

<PAGE>

                                                                             6

     The Company's global short-term strategy is to continue its presence in 
the retrofit market for fleet vehicles and to continue introducing upgrades 
to its existing products.  The Company will also continue its presence in 
both the retrofit and OEM market by promoting its products to meet the 
expected demand for equipment which will allow motor vehicle engines to meet 
the more stringent emission regulations.  The Company's strategy for future 
participation in the U.S. retrofit market will be limited to motor vehicle 
applications which will provide large potential conversions and can be 
economically justified.

     In the long-term, the worldwide demand for alternative fueled vehicles 
is making it feasible for OEM production. The Company has taken steps to 
become a preferred OEM supplier for gaseous fuel components.  During the last 
fiscal year, the Company signed a five-year teaming agreement with General 
Motors Corporation to develop clean gaseous fuel delivery systems for 
passenger cars and medium- and light-duty trucks.  Development programs and 
the commercialization of OEM vehicles with IMPCO systems is on-going in 
Mexico, Australia, Japan, China, and South America.  In addition, the 
Company's recent acquisition of EDO's tank technology and equipment will 
extend the Company's capabilities from tank testing and research and 
development into the next generation of fuel storage systems.  Development of 
fuel storage technology is an important component of the Company's long-term 
strategy to be the premier Tier 1 component supplier to automotive OEMs.  The 
Company believes that product quality is essential for OEM recognition and it 
is continually upgrading its quality assurance program.

     The Company's aftermarket products are primarily marketed through a 
network of specialized distributors which the Company expects to continue to 
utilize for its existing product lines.  However, under recent regulations in 
the U.S., the Company and its installers are required to certify their 
products and services. To meet these requirements, the Company is seeking new 
channels of distribution to complement its existing distributor network.

     The Company has expanded the marketing of its older non-electronically 
controlled products in countries with less stringent emission standards than 
those in the United States.  This strategy is being applied in Central and 
South America, Eastern Europe and the Far East.  In countries such as Mexico 
and Taiwan, where the level of emission standards is increasing, but is not 
as stringent as in the United States, the Company's strategy is to upgrade 
its older products to improve both emission levels and engine performance.

     Significant changes are also occurring in the forklift industry.  The 
increased emphasis on emissions and durability will require engine and 
equipment manufacturers to consider new fuel and engine management products 
as a part of a complete, certified engine package.  The Company is starting 
to work closer with the OEMs in order to manage this change and meet these 
new requirements.  The Company expects the marketing and distribution of 
forklift products to continue with a strong OEM focus.

     The primary growth potential for the industrial engine and heavy duty 
mobile engine business is in the power generation market and the heavy duty 
mobile gas engines used in trucks and buses.  North American generator set 
production continues to increase in response to growing global demand.  Many 
of these sets are fueled by propane or natural gas. The growth in the heavy 
duty mobile engine market will be supported by the increased worldwide 
government mandates for clean air, such as the Clean air Act of 1990, the 
Energy Policy Act of 1992 and the EURO 3 European emission standards.  The 
Company has been developing advanced

electronic heavy duty fuel systems for a number of heavy duty OEMs for trucks 
and buses utilizing compressed natural gas and liquefied natural gas.

COMPETITION AND OTHER MARKET FACTORS

     The Company estimates there are approximately twenty-three manufacturers 
of gaseous fuel delivery components and/or delivery systems.  IMPCO, Landi, 
Tartarini, OMVL, GFI, Koltec & Vialle are estimated to account for over 90% 
of the world market.  The Company has competitors in various worldwide market 
segments in the motor vehicle gaseous fuel equipment industry.  Landi, 
Tartarini and OMVL are major competitors in the Southern Europe and South 
America motor vehicle market.  Vialle is a competitor in the European and 
Australian markets. Koltec is a competitor in the Dutch market and the Far 
East.  GFI primarily serves the North American motor vehicle market.  
Overall, the Company estimates that it has an approximate 35% market share of 
the world market for gaseous fuel delivery components and/or systems for the 
motor vehicle market.

     The Company estimates that it has a greater than 80% market share in the 
material handling and industrial engine market.  Competitors include Nolff 
Manufacturing and AISAN who combined, have less than a 5% market share.  
Other competitors are mostly local manufacturers of repair kits and other 
maintenance components for IMPCO products.

     To be competitive into the future, the Company believes it will be
necessary to continue to enhance its gaseous fuel engine management products
utilizing mass-sensing, electronic and electro- mechanical technology.  The
Company anticipates that the gaseous fuel equipment industry will be
experiencing rapid technological changes in the next ten years.  This should
result in the majority of the existing competitors being limited in the market
place because of their lack of adequate capital or their lack of willingness to
develop high tech, low emission products now being required by future emissions
laws.    However, the Company anticipates new competitors will enter the
alternative fuel marketplace due to the potential increase in the size of the
market. These competitors may include large motor vehicle OEMs who may adapt
their existing gasoline technology to alternative fueled vehicles.

MANUFACTURING

     The Company's products are presently manufactured in the Company's
facilities in Cerritos and Irvine, California.  Manufacturing operations consist
largely of mechanical assembly with light machining. A machining facility is
also operated in Mt. Pleasant, Iowa.  The Company places substantial reliance on
outside vendors for parts, components and electronic assemblies.  It obtains
product components from a variety of domestic motor vehicle and electronic part
suppliers and assemblers, diecasters, metal stamping and machine shops.  In
fiscal year 1998, 10 suppliers accounted for approximately 55% of raw material
purchases and one supplier accounted for approximately 18% of such purchases.

     Material costs represent the major component of cost of sales.
Coordination with suppliers for quality control and timely shipment is
critical to maximize the Company's inventory management.  The Company uses a
computerized material requirements planning system to schedule material flow and
balance the competing demands of timely shipments, productivity and inventory
management.

                                                                             8

     The Company has not experienced, and does not expect to experience, any 
significant difficulty in complying with environmental regulations applicable 
to its manufacturing processes and facilities.

PRODUCT CERTIFICATION

     The Company must obtain certification from the Environmental Protection 
Agency (EPA) to sell certain of its products in the United States and from 
the California Air Resources Board to market certain products in California.  
In September 1997 EPA modified the phase-in program (Option 3 of EPA 
Memorandum 1-A) to ease certification requirements for retrofit conversions 
through model year 1999.  California regulations require that all of model 
year 1997, 1998, and future retrofit conversions be certified, inspected, 
carry a product warranty and comply with new emission standards.  
Manufacturers are also required by the EPA and California regulations to 
conduct 100,000 mile durability tests for retrofit vehicles.  Some other 
states have similar types of regulations.  The Company's continued 
participation in the U.S. retrofit market will be closely monitored as the 
business transitions to OEM vehicles.

     The Company seeks product approval by Underwriters Laboratories, Inc. 
(UL(registered trademark)), the American Gas Association, and international 
approval services on certain products.  While approval is not always 
required, the Company believes such approval enhances the acceptability of 
products in the domestic marketplace.  Many foreign countries also accept 
these agency approvals as satisfying "approval for sale" requirements in 
their markets.

PATENTS AND TRADEMARKS

     The Company holds a number of domestic and foreign patents.  While the 
Company believes that these patents and patent applications protect certain 
proprietary rights and technologies, there can be no assurance that any 
existing and future patents will provide such protection.  Moreover, the 
Company believes that its growth and future success are more dependent upon 
technical expertise and marketing skills than on the ownership of patent 
rights.  Also, other technology exists which performs functions substantially 
equivalent to the technology covered by the Company's patents and patent 
applications, and that technology may be used by others without infringing 
upon the Company's patents.

     The "IMPCO", "BEAM", "GARRETSON" and "CARBURETION J&S" marks are 
registered as trademarks on the United States Principal Register.  They are 
also registered in various other countries throughout the world.  

BACKLOG

     The Company's backlog consists of anticipated sales of products for 
which the Company has confirmed orders scheduled for shipments over the next 
90 days. Such backlog was approximately $10,894,000 and $11,500,000 at April 
30, 1998 and April 30, 1997, respectively.  The Company believes that backlog 
as of any date is not necessarily indicative of future product sales.

EMPLOYEES

The Company employed 446 persons worldwide as of April 30, 1998. None of the 
employees are represented by labor unions, and rapport with employees is 
believed to be good.

YEAR 2000

     The Company recognizes the need to ensure its operations will not be 
adversely impacted by Year 2000 software failures.  Software failures due to 
processing errors potentially arising from calculations using the Year 2000 
date are a known risk.  The Company is addressing this risk to the 
availability and integrity of financial systems and the reliability of 
operational systems both internally and externally.  The Company has 
completed its assessment of the Year 2000 issue through 1) communication with 
key customers, suppliers, financial institutions and others with which it 
conducts business and 2) review of its current internal computer systems to 
identify potential Year 2000 issues.  Based on this assessment, the Company 
is not aware of any key customer, supplier, or financial institution with 
inadequate solutions.  The Company has developed plans to address system 
modifications required by December 31, 1999 and these plans basically require 
the upgrade to new versions of packaged software.  The Company plans to have 
all systems upgraded by December 1998.  The financial impact of making the 
required systems changes is not expected to be material to the Company's 
consolidated financial position, results of operations or cash flows.

Net Revenue
--------------
     The Company's net revenue for fiscal year 1998 increased by $9,255,000 or
15% compared to a $10,253,000 or 20% increase in fiscal year 1997.  For the
current year, contract revenues, primarily from the General Motors Corporation
program, represented $5,482,000 of this increase.

     Product sales for fiscal year 1998 and 1997 increased by approximately 6%
and 21%, respectively.  During 1998, the increase in product sales was
unfavorably reduced by $2,326,000, or 4% as a result of the negative effects of
a strengthening U.S. dollar against foreign currencies.  The following table
sets forth the Company's product sales by application, (all dollars in

     During fiscal year 1998, net revenue attributable to the Company's motor
vehicle products decreased by $1,914,000, or 8%, over 1997.  This decrease in
motor vehicle product sales was unfavorably impacted by the negative effects of
a strengthening U.S. dollar against foreign currencies of $817,000, or 3%. 
During fiscal year 1997, sales for the motor vehicle products increased by
$6,721,000, or 39%, over 1996.  The primary reason for the fiscal year 1997
increase was the addition of the Australian subsidiary which increased
consolidated revenues by $5,294,000 from 1996 to 1997.  The following table sets
forth the Company's worldwide motor vehicle product sales by component parts and
upfitting systems, (all dollars in thousands):

     Sales for the Company's motor vehicle component parts in 1998 decreased
$2,712,000, or 13%, as compared with 1997.  Thirty percent (30%) of this
decrease was attributable to the strengthening of the U.S. dollar. Also, the
decrease resulted from lower product sales for aftermarket conversions in the
U.S. market due to new regulatory requirements shifting the automotive

<PAGE>
                                                                           15

conversion market to direct OEM upfits.  Additionally, the decrease resulted
from lower product sales in Australia as a result of a general economic slowdown
and unfavorable price differentials between petroleum and alternative fuels
which unfavorably impacted the Company's component sales. These decreases were
slightly offset by $603,000 in incremental revenues generated by the newly
acquired Mexican operation.  For fiscal year 1997, the increase in component
parts sales, as compared to 1996, was primarily due to incremental revenue of
$5,294,000 resulting from its Australian acquisition. Increased sales to Latin
America accounted for most of the remaining increase.  Management anticipates
that revenue attributable to the Company's motor vehicle component parts will be
higher during fiscal year 1999 as compared to 1998 primarily as a result of a
full year of operations for the Mexican subsidiary and an increase in demand in
Latin America.  This is a forward-looking statement.  See "Certain Factors"
below.

     During fiscal year 1998, revenue attributable to upfitting vehicles with
the Company's systems increased by $798,000, or 27%, compared to the previous
fiscal year.  This upfitting revenue represented sales of 438 mid-year 1997 GM
pick-ups upfit with the Company's bi-fuel natural gas fuel system and sales of
880 1998 medium-duty dedicated Liquid Propane Gas (LPG) kits under a cross
license agreement with General Motors.  During fiscal year 1997, a portion of
revenue attributable to upfitting vehicles for aftermarket fleet use in 1997
resulted from a program with Ford Motor Company in which the Company's bi-fuel
propane system was utilized in 1996 model year F-150 and F-250 pickup trucks. 
The Ford program was materially completed during the first quarter of fiscal
year 1997. During the third quarter of fiscal year 1997, the Company began
converting postal vehicles to compressed natural gas under a $1.5 million Postal
Service contract.  Deliveries were completed during the fourth quarter of fiscal
year 1997.  During fiscal year 1996, upfitting revenue primarily resulted from a
Postal Service contract to convert postal vehicles to compressed natural gas and
initial shipments of the aforementioned 1996 model year F-150 and F-250 Ford
trucks utilizing the Company's bi-fuel propane system.  Management anticipates
that the commercialization by General Motors Corporation of model year 1998 and
1999 Chevrolet and GMC pickup trucks, and other vehicles, with the Company's
systems will result in significantly higher upfitting revenue during fiscal year
1999.  Although the current labor disputes at General Motors are not impacting
the upfit programs that are in process, the length of the disputes could impact
future delivery schedules and upfitting revenues.  These are forward looking
statements.  See "Certain Factors" below.

     During fiscal year 1998, net revenue attributable to the Company's products
for forklifts and other material handling equipment increased by approximately
$6,202,000, or 27%, over 1997.  This increase in forklift related product sales
was unfavorably impacted by the negative effects of a strengthening U.S. dollar
against foreign currencies of $1,509,000 or 6%.  During fiscal year 1998, the
Company realized increased revenues of $2.4 million from its European operations
which primarily sells material handling equipment.  Without the strengthening
U.S. dollar, revenues from European operations would have increased $3.9 million
for fiscal year 1998.  The remaining increase in sales was derived from domestic
operations.  Both the European and domestic operations realized increases as a
result of the general upswing in economic conditions.  Total revenue from
forklifts and material handling equipment in fiscal year 1997 was comparable to
1996 revenue.  Management anticipates that sales for forklifts and other
material handling equipment in fiscal year 1999 will be comparable to 1998. 
Management projects increases in the European market but will be offset by a
decline in the Asian market.  In addition, it is anticipated in the near future
that the California Air Resources Board (CARB) and the Environmental Protection
Agency (EPA) will adopt emission requirements for forklifts and other material

the motor vehicle industry.  These are forward-looking statements.  See 
"Certain Factors" below.

     During fiscal year 1998, sales of small portable to large stationary 
engines decreased $516,000, or 5% over sales in 1997.  The decrease is 
related to new EPA regulations affecting the small engine aftermarket.  
During fiscal year 1997, sales of small portable to large stationary engines 
increased $3,254,000, or 40%, over sales in 1996. The increase was 
attributable to the Garretson product line purchased in April 1996 and to 
higher demand for large and small power generation units used in power 
replacement and recreational applications. Management anticipates that 
revenue from industrial engines in fiscal year 1999 will be higher compared 
to 1998 levels.  This is a forward-looking statement.  See "Certain Factors" 
below.

     Contract revenue was 12% of total revenue in fiscal year 1998, as compared
to 5% and 6% in 1997 and 1996, respectively.  During 1998, total contract
revenue increased by approximately $5.5 million, or 162%, as compared to 1997. 
During 1997, total contract revenue increased by approximately $304,000, or 10%,
as compared to 1996.  These increases were due to the addition of several
gaseous fueled vehicle platforms for development under the contract with General
Motors Corporation and to development contracts obtained from various federal
and state agencies.  Contract revenue is principally recognized by the
percentage of completion method.  Profits expected to be realized on contracts
are based on the Company's estimates of total contract sales value and costs at
completion.  These estimates are reviewed and revised periodically throughout
the lives of the contracts.  Based on the expected increases in vehicle
platforms and new developmental contracts, management anticipates that contract
revenues during fiscal year 1999 will be significantly higher than 1998.  This
is a forward-looking statement.  See "Certain Factors" below.

     During fiscal year 1998, 1997, and 1996 the Company's product revenue was
generated in the following geographic regions:

Gross Profit Margin 
---------------------  
     The Company's gross profit margin on product sales during fiscal year 1998
was $24,040,000 (39%) compared to $21,095,000 (36%) for the prior year. During
the current year, the Company's domestic operations contributed approximately
$2.0 million to the increase through higher sales volumes and as a result of a
higher gross margin percent realized by lower material costs.  The foreign
operations contributed approximately $.9 million to the gross margin increase
due to the addition of the Mexican operation during 1998, a full year of
reporting for the Australian operation, and higher sales volumes at the European
operation.  The gross profit margin percentage realized at the foreign
operations during the current year is comparable to the percentage realized
during fiscal year 1997.

     The Company's gross profit margin on product sales during fiscal year 1997
was $21,095,000 (36%) compared to $16,476,000 (34%) for fiscal year 

<PAGE>
                                                                            17

1996.  The Company's foreign operations contributed approximately $3.2 
million to this increase as a result of a full year of reporting for the 
European operation and the addition of the Australian operation during fiscal 
1997.  Favorable market driven sales price adjustments and product mix 
improvements from domestic operations translated into higher gross profit 
percents and accounted for the remaining increase in margins from 1996 to 
1997.

     Management anticipates that percent profit margins will continue to be
favorably impacted by higher production volumes and volume purchases, but will
be offset by the higher revenue and inherently lower upfitting margins as
upfitter sales become a larger segment of the Company's business.  In addition,
gross profit percentages at the foreign operations could be lower in the future
as a result of the strengthening U.S. dollar versus foreign currencies. 
However, as the upfitter business and sales volumes increase, overall gross
profits are expected to increase.  These are forward-looking statements.  See
"Certain Factors" below.


Research and Development
---------------------------
     Research and development (R&D) expense for fiscal year 1998 increased by
$4.9 million to $13.3 million, a 57% increase over fiscal year 1997.  R&D
expense directly related to the GM program increased from $3.0 in 1997 to $4.7
million in 1998. R&D expense for fiscal year 1997 increased by $1.3 million to
$8.5 million, an 18% increase over fiscal year 1996.  R&D expense directly
related to the GM program increased from $1.6 in 1996 to $3.0 million in 1997.
The remaining increase in R&D expense was primarily for internally funded
product and other contract R&D work with Perkins Technology Limited and the
Southern California Air Quality Management District.  Management believes the
Company's future success depends on its ability to design, develop and market
new products that interface successfully with new engine electronic technology,
and which meet mandated emission standards.  Management anticipates that R&D
expense during fiscal year 1999 will be continue to be higher than the levels
experienced during fiscal year 1998 due to internally funded development work
and new product development under the GM contract and other contract development
work.  This is a forward-looking statement.  See "Certain Factors" below.


Selling General and Administrative
-------------------------------------
     Selling, general and administrative (SG&A) expense for fiscal year 1998
increased by approximately $1.3 million, or 12%, as compared to the prior fiscal
year.  This increase was primarily due to the addition of the Mexican
subsidiary, inclusion of IMPCO Pty's SG&A expenses for a full fiscal year versus
only ten months in the previous fiscal year, and increased administrative
expenses from the U.S. operations. These expenses included administrative
salaries, incentive compensation, and legal expenses.  However, as a percentage
of net revenues, SG&A expense decreased from 18% in fiscal year 1997 to 17.5% in
the last fiscal year.

     SG&A expense for fiscal year 1997 increased by approximately $2.9 million,
or 35%, as compared to fiscal year 1996.  The combined SG&A expenses for the
Company's European and Australian operations in 1997 were $4,526,000, compared
to $1,357,000 for European expenses only in 1996.  SG&A as a percentage of sales
increased from 16% to 18% due to the Company's foreign operations. The European
facilities distribute alternative fuel products from multiple locations in
Europe and incur higher SG&A expenses as a percentage of sales than the
Company's domestic operations.

<PAGE>
                                                                            18

     Management anticipates that SG&A expense for fiscal year 1999 will be
higher than fiscal year 1998 primarily as a result of additional expenses to
support anticipated growth in revenues and including a full year of the Mexican
operation.  However, as a percentage of net revenues, SG&A expense is expected
to be lower for fiscal year 1999 as compared to 1998.  These are forward-looking
statements.  See "Certain Factors" below.
     
     
Financing charges
--------------------
     Financing charges for fiscal year 1998 decreased by approximately 15% as 
compared to 1997.  The decrease is attributable to lower borrowings on the 
Company's line of credit as compared to the prior year and prepayments on 
long-term borrowings primarily from funds received from the Company's 
redemption of its common stock purchase warrants.  Financing charges for 
fiscal year 1997 increased by approximately 118% over 1996 due to loans 
associated with the acquisitions of IMPCO BV and IMPCO Pty, and the increased 
use of the line of credit.  Management anticipates that financing charges for 
fiscal year 1999 will be lower as compared to the current fiscal year.  This 
is a forward-looking statement.  See "Certain Factors" below.

Provision for income taxes 
--------------------------
     The Company's effective income tax rate for fiscal years 1998, 1997, and 
1996 were 14.7%, 7.0%, and (37.2%), respectively.  Provision for taxes 
consist primarily of federal, state and foreign income 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, R&D tax credits and other items.  During fiscal year 1996, the 
Company reduced its valuation allowance for deferred tax assets as required 
by SFAS No. 109 and recorded $1,700,000 of income tax benefits primarily 
related to the assumed future utilization of net operating loss 
carryforwards.  During fiscal year 1997, the deferred tax asset increased by 
$273,000 to $1,973,000 at April 30, 1997. During fiscal year 1998, the 
deferred tax asset decreased by $373,000 to $1,600,000 at April 30, 1998.  
For federal income tax purposes, the Company has utilized all net operating 
loss carryforwards as of the end of the 1998 fiscal year.  Management has 
determined, based on the Company's history of prior operating earnings and 
its expectations for the future, that operating income of the Company will 
more likely than not be sufficient to recognize fully these net deferred tax 
assets and that the estimated effective annual rate in the future years will 
approximate the statutory rate.  This is a forward-looking statement. See 
"Certain Factors" below.  

Liquidity and Capital Resources
--------------------------------
     The Company uses cash generated from its operations and external financing
to fund capital expenditures, pay dividends on the preferred stock and invest in
and operate its existing operations and new businesses.  Management believes
that such sources of funds will be sufficient to meet the needs of its business
for the foreseeable future.  This is a forward-looking statement.  See "Certain
Factors" below.

     The Company's financial condition remains strong.  The ratio of current
assets to current liabilities was 3.28 at April 30, 1998, as compared to 2.57 at
the end of fiscal year 1997.  The total amount of working capital increased by
$7,827,000 to $26,075,000 at the end of fiscal year 1998.  This 

<PAGE>
                                                                            19

compares to $18,248,000 at the end of the prior year.  Net cash provided by 
operating activities was $1,508,000 during fiscal year 1998, compared to net 
cash provided by operating activities of $3,708,000 and $2,578,000 in fiscal 
years 1997 and 1996, respectively.  The decrease in cash provided by 
operating activities during the last fiscal year resulted from a $3.7 million 
increase in inventory and a $3.4 million increase in accounts receivable.  
The increase in inventory was primarily due to the Algas acquisition and a 
temporary buildup of inventory in anticipation of future upfitter and core 
product sales.  The increase in accounts receivable was primarily due to 
April 1998 billings on the GM program. The decrease in cash provided by 
operating activities was partially offset by a $1.6 million increase in net 
income during fiscal year 1998 compared to the prior fiscal year.

     Net cash used in investing activities in fiscal year 1998 was approximately
$5,763,000, a decrease of approximately $623,000 from 1997. Included in this
amount is equipment purchased from EDO Canada Ltd., dies, tooling and equipment
purchased from the Algas Carburetion Division of PGI International, the
Company's normal capital expenditures for dies, molds and patterns and machinery
and equipment, and the investment in IMPCO Mexicano. Investing activities for
the prior year principally included the purchase of the Company's Australian
subsidiary, which resulted in a net use of cash of approximately $4,655,000. 
Capital expenditures for dies, molds and patterns and machinery and equipment
totaled $3,220,000 in fiscal year 1998, compared to $1,702,000 in fiscal year
1997 and $1,996,000 in fiscal year 1996.  Management projects capital
expenditures during fiscal year 1999, primarily relating to equipment
enhancements and facilities for the development and production of new products,
to be comparable to expenditures during the fiscal year 1998.  The Company
expects to fund a major portion of these expenditures from cash generated from
operations and by use of its bank credit facility.  These are forward-looking
statements.  See "Certain Factors" below.

     Net cash provided by financing activities in fiscal year 1998 was 
approximately $5,051,000.  The Company received approximately $8,454,000 from 
the issuance of common stock as a result of the exercise of common stock 
purchase warrants.  It also received approximately $3,993,000 from the Bank 
of America credit facility to fund the Algas and IMPCO BV acquisitions. The 
Company decreased its borrowing under the operating line of credit by 
approximately $2,407,000 and made $4,403,000 in principal repayments on term 
loans and notes. Approximately $2,335,000 of the loan and note payments 
represented pre-payments. Net cash provided by financing activities in fiscal 
year 1997 was approximately $4,174,000, of which $3,968,000 was from a term 
loan with Bank of America to finance the acquisition of the Company's 
Australian subsidiary.  During fiscal year 1997, the Company increased its 
borrowing under the operating line of credit by approximately $2,050,000 
primarily for current operations and material purchases.

     The Company has a $12,000,000 revolving line of credit and a $5,525,000 
capital lease facility with Bank of America.  At April 30, 1998, 
approximately $3,048,000 and $2,625,000 was outstanding under the revolving 
line of credit and the capital lease facility, respectively.  The revolving 
line of credit expires on August 31, 1999, and the capital lease facility 
expires on December 31, 2003. In addition, the Company's subsidiary in the 
Netherlands has a 3,000,000 NLG (U.S. $1,500,000) credit facility with Mees 
Pierson, a financial institution in the Netherlands.

                                                                            20

Derivative 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.


     (a) 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 forward contracts 
and the management of cash disbursements in local currencies.  At April 30, 
1998 the Company had currency forward contracts protecting U.S.$600,000 in 
inventory purchases.  At April 30, 1998 the fair value of foreign currency 
forward contracts approximated contract values.  On May 29, 1998 the Company 
entered into six currency forward contracts to protect an additional 
U.S.$1,200,000 in inventory purchases.

     The Company seeks to hedge its foreign currency economic risk by 
minimizing its U.S. dollar investment in foreign operations using foreign 
currency term-loans to finance the operations of its foreign subsidiaries. 
The term loans are denominated in local currencies and translated to U.S. 
dollars at period end exchange rates.

     
     (b) Interest Rate Management
     
     The Company uses interest rate swap agreements with Bank of America to 
manage its exposure to interest rate changes and stabilize the cost of 
borrowed funds.  When an agreement is executed, the swap is linked to a 
specific debt instrument.  At April 30, 1998, the Company had $4,160,000 
secured under fixed interest rate agreements at a weighted average fixed 
interest rate of 7.78%.  Absent these fixed rate agreements, the weighted 
average variable rate for this debt at April 30, 1998 would have been 7.38%.
At April 30, 1998 the fair value of interest rate swap agreements 
approximated carrying value.  On May 29, 1998 the Company secured an 
additional $3,271,000 under a fixed interest rate agreement.

Year 2000
---------
     The Company recognizes the need to ensure its operations will not be
adversely impacted by Year 2000 software failures.  Software failures due to
processing errors potentially arising from calculations using the Year 2000 date
are a known risk.  The Company is addressing this risk to the availability and
integrity of financial systems and the reliability of operational systems both
internally and externally.  The Company has completed its assessment of the Year
2000 issue through 1) communication with key customers, suppliers, financial
institutions and others with which it conducts business and 2) review of its
current internal computer systems to identify potential Year 2000 issues.  Based
on this assessment, the Company 



<PAGE>
                                                                            21

is not aware of any key customer, supplier, or financial institution with 
inadequate solutions.  The Company has developed plans to address system 
modifications required by December 31, 1999 and these plans basically require 
the upgrade to new versions of packaged software.  The Company plans to have 
all systems upgraded by December 1998.  The financial impact of making the 
required systems changes is not expected to be material to the Company's 
consolidated financial position, results of operations or cash flows.

Certain Factors
----------------
     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:

DELAY IN IMPLEMENTATION OF GOVERNMENT REGULATIONS
The market for alternative fueled vehicles and the demand for the Company's
products are, to a significant degree, driven by local, state and federal
regulations in the United States related to air quality and requiring conversion
of motor vehicles to alternative fuels.  The Company's international business is
also affected by similar foreign governmental regulations.  Timing in the
implementation of these regulations could have an unfavorable impact on the
Company's financial performance.

DEPENDENCE ON ALTERNATIVE FUEL MARKET
Although the Company believes that there will be substantial growth in the
market for alternative fueled engines, especially among fleet vehicle owners,
there can be no assurance that such growth will materialize or, if such growth
does occur, that it will result in increased sales of the Company's products. 
The Company's products are designed for gaseous alternative fueled vehicles, but
not for alternative fuels such as electricity, methanol, ethanol and hydrogen. 
If the major growth in the alternative fuel market is solely for such fuels, the
Company will be adversely affected.  At present, the lack of a well-developed
infrastructure for the supply of alternative fuels is limiting growth in the
alternative fuel engine market.  Such an infrastructure is necessary for
widespread use of all alternate fuels.  

<PAGE>
                                                                            22

DEPENDENCE ON NEW PRODUCTS
The Company believes that its future success is dependent upon its ability to
design and market new fuel management products as well as enhance its existing
products.  It believes that the markets for its products will be characterized
by rapidly changing technology, new product introductions and the entry of new
competitors.  The Company's 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 achieve
market acceptance in a timely manner will significantly affect its future
performance.

FLUCTUATIONS IN OPERATING RESULTS
The Company's 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, the uncertainty of timing of deliveries of vehicles to be upfitted,
the timing of implementation of government regulations promoting alternative
fuel vehicles, as well as general economic factors.

RISK OF INTERNATIONAL OPERATIONS
The Company operates in Europe, Australia and Mexico and markets its products
and technologies in other international markets, including both industrialized
and developing countries.  The Company's international operations are subject to
various risks common to international activities, such as exposure to currency
fluctuations, the inherent difficulty of administering business abroad and the
need to comply with a wide variety of foreign import and United States export
laws.  The Company's competitiveness in overseas markets may be negatively
impacted when there is a significant increase in the value of the dollar against
foreign currencies where the Company does business.

COMPETITION
The Company believes that competition in the alternative fuel engine marketplace
is increasing, particularly in the growing market for propane and natural gas
fueled vehicle products.  Some of the current competitors and potential future
competitors are large, well-financed companies, with financial and marketing
resources and research and development capabilities that are substantially
larger than those of the Company.

ENTRY OF ORIGINAL EQUIPMENT MANUFACTURERS INTO MARKET
As the market for alternative fueled vehicles increases, original equipment
manufacturers may find it advantageous to develop and produce their own fuel
management equipment rather than purchasing such equipment from suppliers such
as the Company.  If this occurs, the total potential demand for the Company's
products could be adversely impacted.

ABILITY TO MEET OEM SPECIFICATIONS
In 1995 the Company began to offer complete alternative fuel systems, which
include tanks, brackets, electronics and all other under-hood components
required to convert a motor vehicle to alternative fuels.  Customers for such
systems require that they meet OEM standards.  These requirements have resulted
in increased development, manufacturing, warranty and administrative costs.  If
these costs increase significantly, the Company's profitability could be
adversely affected.

DEPENDENCE ON QUALIFIED PERSONNEL
The Company is dependent upon a limited number of key management and technical
personnel.  In addition, as products become complex, the Company's future
success will depend in part upon its ability to attract and retain highly
qualified personnel.

<PAGE>
                                                                            23

INCREASED WARRANTY CLAIMS
Vehicle manufacturers are, in response to consumer demand, providing
increasingly longer warranty periods for their products.  Suppliers, such as the
Company, are required to provide correspondingly longer product warranties. 
Consequently, the Company could incur substantially greater warranty claims in
the future.

NEED TO COMPLY WITH GOVERNMENTAL REGULATIONS
The Company must obtain product certification from governmental agencies such as
the Environmental Protection Agency and the California Air Resources Board to
sell certain of its products in the United States automotive markets.  A
substantial portion of the Company's future sales will depend upon sales of fuel
management products that are certified to meet existing and future air quality
and energy standards.  Although the Company believes its technologies will
permit its existing and new products to meet these standards, there can be no
assurance that this will occur.

ABILITY TO SECURE FUTURE DEVELOPMENT CONTRACTS
The Company has obtained funding under development contracts with original 
equipment manufacturers and governmental agencies to develop specified 
products. There can be no assurance that such funding will be obtainable in 
the future, the lack of which may significantly impact the Company's ability 
to develop and market new products and technologies.

PRODUCT LIABILITY & RECALL
Although the Company carries and plans to continue to carry product liability
and recall insurance, there can be no assurance that such coverage is adequate
or that adequate coverage will continue to be available or, if available, that
it will be available at an acceptable cost.

LABOR DISPUTES AT OEM FACILITIES
As the Company enhances its automotive upfit programs with OEMs, the Company is
becoming increasingly dependent on OEM production and the associated labor
forces at OEM sites.  Most of the labor force at OEM facilities are represented
by labor unions.  There can be no assurance that labor disputes will not occur. 
In the event of a dispute, upfit sales may be adversely impacted.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS



The Board of Directors and Stockholders
IMPCO Technologies, Inc.

We have audited the accompanying consolidated balance sheets of IMPCO 
Technologies, Inc. [formerly AirSensors, Inc.] as of April 30, 1998 and 1997, 
and the related consolidated statements of income, stockholders' equity and 
cash flows for each of the three years in the period ended April 30, 1998.  
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 generally accepted auditing 
standards.  Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation.  We believe that our audits 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. [formerly AirSensors, Inc.] at April 30, 1998 and 
1997, and the consolidated results of its operations and its cash flows for 
each of the three years in the period ended April 30, 1998, in conformity 
with generally accepted accounting principles.  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.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (a)  BASIS OF PRESENTATION AND DESCRIPTION OF THE BUSINESS - The 
consolidated financial statements of IMPCO Technologies, Inc. (IMPCO or the 
Company) [effective September 15, 1997, AirSensors, Inc. changed its name to 
IMPCO Technologies, Inc.] include the accounts of the Company and it's majority 
owned subsidiary IMPCO Technologies B.V. (IMPCO BV) [Effective January 1, 1998, 
IMPCO Media Europe B.V. changed its name to IMPCO Technologies B.V.], its 
majority-owned subsidiary Grupo I.M.P.C.O. Mexicano, S. de R.L. de C.V. 
(I.M.P.C.O. Mexicano) [Effective January 20, 1998 Industrias Mexicanas de 
Productos de Combustibles, S. de R.L. de C.V. changed its name to Grupo 
I.M.P.C.O. Mexicano, S. de R.L. de C.V.] and its wholly owned subsidiary IMPCO 
Technologies, Pty. Limited (Impco Pty).  All significant intercompany accounts 
and transactions have been eliminated in consolidation. 

     The Company is engaged in the design, manufacturing and marketing of 
gaseous fuel delivery systems and related devices that allow internal 
combustion engines to operate on alternative fuels, primarily propane and 
natural gas.  Worldwide the Company's products are sold to distributors and 
original equipment manufacturers (OEMs).

     (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, is provided using
the straight-line method over the shorter of the assets' estimated useful lives
or the lease terms.

     (d)  INTANGIBLES ARISING FROM ACQUISITION - Intangibles arising from
acquisition are recorded based on the excess of the cost of the acquisition over
amounts assigned to tangible assets and liabilities.  These intangible assets
include goodwill, product rights and trademarks.  The intangible assets are
being amortized using the straight-line method over their estimated lives of
twenty years.

     (e)  DEFERRED COSTS - Deferred costs, included in other assets, represent
amounts paid for software and other costs incurred after the establishment of
technological feasibility.  These costs are capitalized and subsequently
amortized using the straight-line method over the estimated economic life of the
related product.

     (f) WARRANTY COSTS - Estimated future warranty obligations related to 
certain products are provided by charges to operations in the period in which 
the related revenue is recognized.  Estimates are based, in part, on 
historical experience.

     (g)  RESEARCH AND DEVELOPMENT COSTS - Research and development costs are
charged to expense as incurred.  Equipment used in research and development with
alternative future uses is capitalized.

<PAGE>


     (h)  CONTRACT REVENUE RECOGNITION - Contract revenue is principally
recognized by the percentage of completion method.  Profits expected to be
realized on contracts are based on the Company's estimates of total contract
sales value and costs at completion.  These estimates are reviewed and revised
periodically throughout the lives of the contracts.

     (i)  MINORITY INTEREST IN SUBSIDIARY - In October 1995, IMPCO purchased 51
percent of IMPCO BV.  In July 1996, IMPCO acquired IMPCO Pty which included a 50
percent share in a subsidiary (Gas Parts, NSW.)  In January 1998, IMPCO Pty
acquired the remaining 50 percent of Gas Parts, NSW.  In December 1997, IMPCO
acquired a 90 percent interest in IMPCO Mexicano.  Minority interest represents
the minority shareholder's proportionate share of equity in the IMPCO BV,  Gas
Parts, NSW and IMPCO Mexicano subsidiaries. The balance sheet amounts in
minority interest at April 30, 1998 represent 49 percent of the equity held by
the single minority shareholder in IMPCO BV and ten percent of the equity held
by the single minority shareholder in I.M.P.C.O. Mexicano.

     (j)  NET INCOME PER SHARE - In February 1997, the Financial Accounting
Standards Board issued SFAS No. 128 "Earnings Per Share".  Statement 128
replaced the previously reported primary and fully diluted earnings per share
with basic and diluted earnings per share.  Basic income per share is computed
by dividing net income applicable to common stock by the weighted average shares
outstanding during the period.  Unlike primary earnings per share, common stock
equivalents, including outstanding stock options and warrants, are excluded from
the Basic calculation.  Diluted earnings per share, similar to the fully diluted
computation, is computed based on the weighted average number of common shares,
all common stock equivalents, and if dilutive, shares issued upon conversion of
preferred stock.   All earnings per share amounts for all periods have been
presented, and where necessary, restated to conform to the Statement 128
requirements.

     (k)  STOCK BASED COMPENSATION - In October 1995, the Financial Accounting
Standards Board issued SFAS No. 123 "Accounting of Stock Based Compensation",
which established accounting and reporting standards for stock based employee
compensation plans effective after fiscal year 1996.  SFAS 123 encourages
entities to adopt the new method ("fair value based method") of accounting; 
however it also allows an entity to continue to measure compensation cost
prescribed under existing rules ("intrinsic value based method") prescribed by
Accounting Principle 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 9).

     (l)  IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE 
DISPOSED OF - During the first quarter of 1997, the company adopted SFAS No. 
121 "Accounting for Impairment of Long-Lived Assets and Long-Lived Assets to 
be Disposed Of" which established accounting standards for the impairment of 
long-lived assets, certain identifiable intangibles, and goodwill related to 
those assets.  The Statement requires impairment losses to be recorded on 
long-lived assets used in operations when indicators 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) are present and the undiscounted cash flows estimated to be 
generated by those assets are less than the assets' carrying amount.  Since 
adoption, the Company did not experience 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. The 
adoption of SFAS No.121 did not have a material effect on the consolidated 
financial position or results of operations of the Company.

<PAGE>

     (m)  USE OF ESTIMATES - The preparation of financial statements in
conformity with generally accepted accounting principles requires that
management make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities as of
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

     (n)  RECLASSIFICATIONS - Certain reclassifications have been made to the
fiscal year 1996 and 1997 consolidated financial statements to conform to the
fiscal year 1998 presentation.

     (o)  FOREIGN CURRENCY TRANSLATION - Assets and liabilities of the Company's
foreign subsidiaries are generally translated at current exchange rates, and
related revenues and expenses are translated at average exchange rates in effect
during the period.  Resulting translation adjustments are recorded as a foreign
currency component in shareholders' 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 which operate as a hedge of an identifiable foreign
currency commitment, or as a hedge of a foreign currency investment position,
are included in the results of operations as incurred.

     (p)  FAIR VALUE OF FINANCIAL INSTRUMENTS - The Company's financial
instruments recorded on the balance sheet include cash, short-term bank debt,
and long-term bank debt.  Because of the short maturity, the carrying amount of
cash and short-term bank debt approximates fair value.  Since the interest rates
on the long-term debt are reset at intervals not to exceed twelve months, the
carrying value of the Company's long-term debt approximates fair value.

     At April 30, 1998, off balance sheet derivative financial instruments
include foreign currency forward contracts and interest rate swap agreements
(see note 4).

     The Company enters into foreign currency forward contracts to hedge the net
receivable/payable position arising from intercompany transactions by its
foreign subsidiaries.  Foreign currency contracts reduce the Company's exposure
to unfavorable fluctuations in foreign currencies versus the U.S. dollar. 
Foreign currency gains and losses on intercompany transactions are not deferred.
     
     Interest rate swap agreements are used by the Company to manage interest
rate risk on its floating rate debt portfolio.  Each interest rate swap is
matched as a hedge against a specific debt instrument and has the same notional
amount and tenor as the related debt instrument principle.  Fair value of these
instruments is based on estimated currency settlement cost.

ACCOUNTING PRONOUNCEMENTS

     The Financial Accounting Standards Board has issued certain Statements of
Financial Accounting Standards (SFAS) which are applicable to the Company.  SFAS
No. 130, "Reporting Comprehensive Income", which is effective for fiscal years
beginning after December 15, 1997; SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information", which is effective for fiscal years
beginning after December 15, 1997; and, SFAS No. 133, "Accounting for Derivative
Instruments and for Hedging 

<PAGE>

Activities" which is effective for fiscal years beginning after June 15, 1999.

     SFAS No. 130 requires all items required to be recognized under 
accounting standards as components of comprehensive income be reported in a 
financial statement that is displayed with the same prominence as other 
financial statements.  The changes in cumulative translation adjustments, 
reported through stockholders' equity, is currently the Company's only 
component of comprehensive income.  The Company currently plans to adopt this 
standard in fiscal 1999.

     SFAS No. 131 requires a public enterprise to report financial and 
descriptive information about its reportable operating segments based upon 
the way management organizes segments within the enterprise for making 
operating decisions and assessing performances.  Adoption of this standard 
will not require any material changes in current disclosures.  The Company 
plans to adopt the standard in fiscal 1999.

     SFAS No. 133 requires all 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.  Though the accounting treatment and criteria for each of the 
three types of hedges is unique, they all result in offsetting changes in 
value or cash flows of both the hedge and the hedged item being recognized in 
earnings in the same period. 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.  As this standard was recently issued, the Company will 
begin analyzing the various requirements in order to determine what impact, 
if any, it will have on its disclosures, financial position, results of 
operations, and cash flows.  Currently, the Company does not anticipate 
adopting this standard before fiscal 2001.

2.   ACQUISITIONS

     (a) ALGAS CARBURETION
     
     On December 5, 1997, the Company purchased certain manufacturing equipment
and inventory of the Algas Carburetion Division of PGI International.  The
purchase price of $2,400,000 was paid in cash.  On the same day, the Company
acquired a 90% interest in Industrias Mexicanas de Productos de Combustibles, S.
de R.L. de C.V.  Effective January 20, 1998 Industrias Mexicanas de Productos de
Combustibles, S. de R.L. de C.V.  changed its name to Grupo I.M.P.C.O. Mexicano,
S. de R.L. de C.V.("Grupo I.M.P.C.O. Mexicano").  The purchase price of $961,000
was paid in cash.  Immediately prior to the Company's acquisition of a 90%
ownership interest in Grupo I.M.P.C.O. Mexicano, Grupo I.M.P.C.O. Mexicano
acquired certain assets of the carburetion division of Algas Mexicana, S.A. de
C.V.  These acquisitions were financed by term loans of approximately $3.3
million provided by Bank of America [See note 3(a)(iv)].

     (b) EDO CANADA, LTD.  

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

     (c) ATECO AUTOMOTIVE PTY. LTD.

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

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

     The purchase price was financed through approximately $4,000,000 of term
loans provided by Bank of America NT&SA and its Sydney Australia Branch [See 
note 3(a)(iii) and note 3(b)].  The term loans are three-year loans with a 
five-year amortization schedule and interest at market rates.  In addition, 
accounts receivables due to IMPCO by Ateco, totaling approximately 
$1,852,000, were offset against the purchase price.  The balance of the 
purchase price was paid with proceeds from IMPCO's existing line of credit 
with Bank of America NT&SA. The Company recognized approximately $3,601,000 
of intangible assets arising from acquisition which will be amortized over 20 
years.  The purchase price allocation is based on management's best estimates 
at the acquisition date.  The tangible assets and liabilities have been 
recorded at their estimated fair values as of the date of acquisition as 
follows:

     On January 31, 1998, the Company's wholly-owned subsidiary IMPCO
Technologies Pty. Limited acquired the remaining 50% ownership interest in Gas
Parts (NSW) Pty. for A$225,000 (US$148,500) in cash.  The acquisition was
accounted for using the purchase method of accounting for step-acquisitions. 
Excess purchase price over fair market value of the underlying assets of 
A$141,000 (US$93,000) was allocated to goodwill.

     (d)  IMPCO TECHNOLOGIES B.V.

     On October 31, 1995, the Company, through its wholly owned subsidiary 
IMPCO, acquired 51 percent of the outstanding stock of Technisch Bureau Media 
B.V., a private company in the Netherlands, from Centradas B.V., a private 
company in the Netherlands, for cash in the amount of 3,187,500 Dutch 
Guilders (U.S. $2,023,000).  Effective January 1, 1998, IMPCO Media Europe BV 
changed its name to IMPCO Technologies B.V. (IMPCO BV).  IMPCO B.V. has 
distributed IMPCO's gaseous fuel carburetion systems and related devices for 
use in internal combustion engines since 1972.  IMPCO BV services the 
European marketplace from its headquarters in the Netherlands and through its 
subsidiaries in Germany, France and the United Kingdom.

     The acquisition was financed through a term loan provided by Bank of 
America which will be repaid over a five-year period with interest at market 
rates [See Note 3(a)(ii)].  The acquisition of IMPCO BV has been accounted 
for under the purchase method of accounting and has been included in the 
consolidated financial statements since October 31, 1995, the date of 
acquisition.  The Company recognized $2,100,000 of intangible assets arising 
from acquisition which will be amortized on the straight-line method over 20 
years.  The tangible assets and liabilities of IMPCO B.V. have been recorded 
at their estimated fair market values at the date of the acquisition as 
follows:

     On May 1, 1998 the Company purchased the remaining 49% of IMPCO BV from 
Depa Holding BV for 1,400,000 Dutch Guilders (U.S. $693,000).  As a condition 
precedent to purchase of the outstanding shares, IMPCO BV retired the debt 
outstanding to Depa Holding BV with the proceeds from the term loan granted 
by Bank of America NT&SA [See Note 3(a)(v)].  The acquisition was accounted 
for using the purchase method of accounting for step-acquisitions. The 
Company recognized approximately $238,000 of goodwill arising from the 
acquisition of the 49% interest which will be amortized on the straight-line 
method over 20 years.    

3.   DEBT PAYABLE

     (a) BANK OF AMERICA NT&SA

     On October 7, 1997 IMPCO amended its credit facility with Bank of America
NT&SA by extending the term of the revolving line of credit for a twelve month
period ending August 31, 1999.  The amended credit facility also increased the
revolving line of credit by $4,000,000 to $12,000,000, and added a $4,000,000
term loan facility for possible future acquisitions.  On February 4, 1998 the
Company amended the credit facility by extending the payment terms of the
acquisition facility from three years to five years.  The amended credit
facility also includes, as part of the $12,000,000 revolving line of credit, a
$1,000,000 revolving line of credit to the Company's Mexican subsidiary.

<PAGE>
                                                                           44

     On March 18, 1998 the Company further amended the credit facility by
lowering the interest rate on the revolving line of credit and the acquisition
facility by one-quarter of one percentage point.  On April 29, 1998 the Company
amended the credit facility with the bank by adjusting the acquisition facility
disbursement terms.  The acquisition facility was adjusted to allow for a second
disbursement of $692,520.78 for the purchase of the minority portion of IMPCO
Technologies B.V.

     On April 27, 1998 IMPCO Technologies B.V. entered into a credit facility
with Bank of America NT&SA through its Amsterdam branch for a term loan for
$2,100,000 or an equivalent amount in freely convertible foreign currencies.
     
     On September 23, 1997, the Company expanded the capital lease facility from
$3,525,000 to $5,525,000 and extended the expiration date to August 31, 2003. 
Including the revolving line of credit, the capital lease facility and the
acquisition facilities, the total Bank of America credit facility was
$22,378,000 at April 30, 1998.


         (i) REVOLVING LINE OF CREDIT

     The revolving line of credit bears interest, payable monthly, at a
fluctuating per annum rate equal to the Bank of America reference rate minus
one-quarter of one percentage point (which was 8.25% on April 30, 1998).  The
Company may elect to have all or portions of the line bear interest at an
alternative interest rate agreed upon by the Bank for periods of not less than
30 days nor more than one year.  At April 30, 1998, the total outstanding line
of credit balance of $2,650,000 was subject to the reference rate.

     The credit facility provides a Mexican peso line of credit equivalent to
$1,000,000 for Grupo I.M.P.C.O. Mexicano and is included as part of the existing
$12,000,000 revolving line of credit between the Company and Bank of America
NT&SA.  For U.S. borrowings, the revolving line of credit carries interest,
payable monthly, at a fluctuating per annum rate equal to the Bank of America
reference rate or the London Interbank Offering Rate (LIBOR) plus 1.75% (7.41%
at 4/30/98).  For Mexican borrowings, the revolving line of credit carries
interest, payable monthly, at a fluctuating per annum rate equal to the Bank of
America Mexico (BAMSA) cost of funds plus 1.50% or the TIIE plus 1.50% (21.02%
at 4/30/98).  The TIIE is the Interbank Interest Equilibrium Rate calculated by
the Bank of Mexico for the most recent period of twenty-eight (28) days prior to
commencement of the interest period.  The Company may prepay the facility, in
full or in part, upon two-business days notice, subject to break funding costs,
if any.  The minimum prepayment is US$250,000.  At April 30, 1998, the total
outstanding line of credit balance of Ps. 3,375,775 (U.S. $397,805) was subject
to the BAMSA cost of funds rate (22.8% at 4/30/98).

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

     The line 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 April 30, 2002.  The amount of
letters of credit outstanding at any one time may not exceed $2,000,000 for
commercial letters of credit and $750,000 for standby letters of credit.  At
April 30, 1998, a standby letter of credit totaling $375,000 was outstanding.

<PAGE>
                                                                           45

The maximum amount available at any one time on the revolving line of credit and
the commercial letters of credit is $12,000,000.

         (ii) TERM LOAN FOR ACQUISITION OF IMPCO TECHNOLOGIES B.V.

     This term loan bears interest, payable monthly, at the Bank's reference
rate.  The Company may elect to have all or portions of the term loan bear
interest at an alternative interest rate agreed upon by the Bank for periods of
not less than 30 days nor more than one year.  The alternative interest rate is
based on the Offshore rate plus 1.50%.  Each alternative rate portion must be
for an amount not less than $500,000 and may not include any portion of
principal that is scheduled to be repaid before the last day of the applicable
interest period.  On October 20, 1997, the Company entered into a 34 month
interest rate swap agreement with Bank of America NT&SA ending August 31, 2000,
that fixes the interest rate on the facility at 7.90%.  At April 30, 1998, the
total outstanding balance was $1,025,000.


        (iii) TERM LOAN FOR THE ACQUISITION FOR ATECO

     On October 31, 1997, the Company retired this facility early by making a
balloon payment of $1,600,000.


         (iv) TERM LOAN FOR FUTURE ACQUISITION(S)

     This term loan bears interest, payable monthly, at the Bank's reference
rate.  The Company may elect to have all or portions of the term loan bear
interest at an alternative interest rate agreed upon by the Bank for periods of
not less than 30 days nor more than one year.  The alternative interest rate is
based on the Offshore rate plus 1.75%.  Each alternative rate portion must be
for an amount not less than $500,000 and may not include any portion of
principal that is scheduled to be repaid before the last day of the applicable
interest period.  Principal is payable in 20 successive quarterly installments,
starting on the last day of the third month after funding.  The first 19
installments will be equal to 1/19 of the original principal amount with the
last installment equal to the remaining balance.  The term loan may be prepaid,
with payments applied in inverse order of maturity, in whole or in part, at any
time.  

     On December 5, 1997, the Company utilized $3.3 million of the $4 million
term loan for the acquisition of Algas (See Note 2).  On February 3, 1998, the
Company entered into a 58-month interest rate swap agreement with Bank of
America ending December 5, 2002 that fixes the interest rate on the facility at
7.74%.  At April 30, 1998, the total outstanding balance was $3,135,000.
      
     On April 30, 1998, the Company utilized $693,000 of the remaining term loan
facility for the acquisition of the minority shares of IMPCO Technologies B.V.
(See Note 2).  The outstanding balance of $693,000 was subject to the offshore
rate (7.46%).  On May 29, 1998, the Company entered into a 59-month interest
rate swap agreement with Bank of America ending April 15, 2003 that fixes the
interest rate on the facility at 7.80%.
     

       (v) IMPCO TECHNOLOGIES B.V. TERM LOAN

     On May 1, 1998 IMPCO Technologies B.V. borrowed 4,200,000 Dutch Guilders
(U.S. $2,098,000) to refinance the existing term loan with Depa Holdings as a
condition precedent to the sale of the minority shares in IMPCO Technologies
B.V.  This term loan bears interest, payable monthly, at the 

<PAGE>
                                                                           46

Amsterdam Interbank Offered Rate for the corresponding period of the advance, 
plus 1.50%. Principal is payable in 19 successive quarterly installments of 
210,000 Dutch Guilders and the remaining balance is payable as the 20th 
installment.  The term loan may be prepaid, with payments applied in inverse 
order of maturity, in whole or in part, at any time. At May 1, 1998, the 
outstanding balance of 4,200,000 Dutch guilders bore an interest rate of 
4.94%.

        (vi) CAPITAL LEASE FACILITY

     The capital lease facility is available in incremental draws of $50,000 or
more to finance acquisitions of equipment such as machinery, dies, molds, office
furniture, and motor vehicles.  At April 30, 1998, approximately $2,625,000 was
outstanding and approximately $1,746,000 remained available.  Each draw is to be
repaid in twenty consecutive equal quarterly installments and bears interest at
either a variable rate or fixed rate of interest.  The fixed rate of interest is
the U.S.  Treasury note bond-equivalent yield per annum corresponding to the
number of months remaining on the draw, plus 2.55 percentage points.  The
variable rate of interest is equal to Bank of America's London Branch 3-month
LIBOR rate plus 2.15 percentage points.  At April 30, 1998, all draws were
subject to the variable rate of interest.  The long-term and short-term portions
of the capital lease facility are included in other long-term liabilities and
other accrued expenses, respectively, on the Company's balance sheet.  On May
29, 1998, the Company entered into a 59-month interest rate swap agreement with
Bank of America ending April 15, 2003 that fixes the interest rate on $2,578,000
of the facility at 8.50% for fundings 1 through 18 and 8.20% for fundings 19
through 22.

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

        (vii)  LOAN COVENANTS AND COLLATERAL

     The Bank of America 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, 1998, the
Company was in compliance with all covenants.

     (b) TERM LOAN - BANK OF AMERICA, AUSTRALIA

     On January 31, 1998, the Company retired this facility by making a payment
of A$1,000,000 (U.S. $650,000).

<PAGE>


     (c) TERM LOAN - DEPA HOLDING B.V.

     As of April 30, 1998, the outstanding principal balance on the term loan 
was 4,200,000 Dutch Guilders (U.S. $2,100,000) and was subject to the annual 
interest rate of 4.11%.  On May 1, 1998, as a condition precedent to the sale 
of the minority shares held by Depa Holding B.V., IMPCO Technologies B.V. 
retired this facility from the proceeds of the term loan facility granted by 
Bank of America NT&SA.

     (d)  CREDIT FACILITY - MEES PIERSON

     In February of 1996, IMPCO Technologies B.V. secured a 3,000,000 Dutch 
Guilder (U.S. $1,500,000) 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 
Technologies B.V.'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, 1998, the interest 
rate was 5.125% and there was no outstanding balance on the credit facility.

     Annual maturities of long-term debt for the five years subsequent to May 1,
1998 (in millions) are as follows: 1999 - $1.4; 2000 - $1.5; 2001 - $1.3; 2002 -
$1.1; 2003 - $1.0; and thereafter - $.7.


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.


     (a) 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 forward contracts 
and the management of cash disbursements in local currencies.  At April 30, 
1998 the Company had currency forward contracts protecting U.S.$600,000 in 
inventory purchases.  At April 30, 1998 the fair value of foreign currency 
forward contracts approximated contract values.  On May 29, 1998 the Company 
entered into six currency forward contracts to protect an additional 
U.S.$1,200,000 in inventory purchases.

     The Company seeks to hedge its foreign currency economic risk by 
minimizing its U.S. dollar investment in foreign operations using foreign 
currency term-loans to finance the operations of its foreign subsidiaries. 
The term loans are denominated in local currencies and translated to U.S. 
dollars at period end exchange rates.

<PAGE>

     (b) Interest Rate Management
     
     The Company uses interest rate swap agreements with Bank of America to 
manage its exposure to interest rate changes and stabilize the cost of 
borrowed funds.  When an agreement is executed, the swap is linked to a 
specific debt instrument.  At April 30, 1998, the Company had $4,160,000 
secured under fixed interest rate agreements at a weighted average fixed 
interest rate of 7.78%. Absent these fixed rate agreements, the weighted 
average variable rate for this debt at April 30, 1998 would have been 7.38%. 
At April 30, 1998 the fair value of interest rate swap agreements 
approximated carrying value.  On May 29, 1998 the Company secured an 
additional $3,271,000 under a fixed interest rate agreement.

     (c)  Fair Value of Long-Term Debt

     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, 1998 the fair value of the 
Company's long-term debt approximated carrying value.

5.   INCOME TAXES

1997 and 1996 has been reduced by the utilization of approximately 
$5,045,500, $3,953,000 and $1,650,000 of federal net operating loss 
carryforwards, respectively.  During fiscal years 1998, 1997 and 1996, the 
current provision for state taxes was reduced by the utilization of 
approximately $375,000, $246,000 and 140,000, respectively, of investment 
and/or research tax credits. In addition, in fiscal year 1996 a state income 
tax refund of approximately $82,000 was applied to the 1996 provision.

     During the fourth quarter of fiscal year 1996, the Company reevaluated 
the valuation allowance for its deferred tax assets.  Based on this 
reevaluation, which considered among other items projections as to future 
taxable income, the Company determined that the valuation allowance should be 
reduced by $1,700,000 principally due to the presumed future use of federal 
net operating loss carryforwards.  This reduction in the valuation allowance 
is reflected in the deferred tax benefit for fiscal year 1996.  During the 
fourth quarter of fiscal year 1997, the Company reevaluated the valuation 
allowance for its deferred tax assets.  Based on this reevaluation, which 
considered among other items, projections as to future taxable income, the 
Company determined that the valuation allowance should be reduced by 
$1,559,000 principally due to the presumed future use of federal net 
operating loss carryforwards.  This reduction in the valuation allowance is 
reflected in the deferred tax benefit for fiscal year 1997.  During fiscal 
year 1998, the Company determined that there is no need to carry a valuation 
allowance and therefore reduced the valuation allowance by $510,000.   This 
reevaluation was based on projections of future taxable income.

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

     (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.

     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 (ERISA).  All employees who are at 
least age twenty-one or older are eligible to participate in the Plan on the 
first day of any calendar month following one year of service with the 
Company.  Employees of the Company who elect to participate in the Plan may 
contribute into the Plan not less than 1% nor more than 15% of compensation.  
The Company's matching contributions are discretionary and match elective 
salary deferrals up to 1.8% of compensation. Approximately 42% of eligible 
employees were enrolled in the 401(k) plan at April 30, 1998.  Employer 
contributions totaled approximately $98,000, $95,000, and $85,000 for fiscal 
years ended 1998, 1997 and 1996.

7.   STOCKHOLDERS' EQUITY


     (a)    1993 SERIES 1 PREFERRED STOCK

     The holders of the Company's' 1993 Series 1 Preferred Stock (1993 
Preferred) are 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, 1998). 
The dividend rate, which is adjusted on the first day of each calendar 
quarter, is based on the Seafirst Bank prime rate of interest plus 1.5% 
(assuming a deemed principal value of $1,000 per share).  Holders of 1993 
Preferred are entitled to vote on all matters brought before the common 
stockholders and have the number of votes equal to the number of full shares 
of common stock into which the 1993 Preferred could then be converted.

     The 1993 Preferred is convertible into common stock at the option of the 
holders by dividing the then conversion price into its liquidation value of 
$1,000 for each share being converted.  At April 30, 1998, the conversion 
price was $5.29 per share.  The conversion price decreases if additional 
shares of common stock are issued for a consideration per share less than the 
then conversion price.

     Each share of 1993 Preferred automatically converts into shares of 
common stock upon the Company reporting audited consolidated net earnings of 
$5,000,000 for a fiscal year, or upon the closing of an underwritten public 
offering of the Company's common stock in which the Company realizes gross 
proceeds of $10,000,000 or more and the public offering price is at least 
$12.00 per share, provided that all dividends in arrears are paid and the 
obligation of the underwriters is that all offered shares must be purchased. 
Commencing March 31, 1999, the Company has the right to convert the 1993 
Preferred to 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.

(b)  WARRANTS TO PURCHASE COMMON STOCK

     In the fourth quarter of the current fiscal year, the Company issued a 
contingent warrant certificate that entitles a contractor to purchase 38,750 
shares of Common Stock at a price of $12.00 per share.  The warrant vests and 
becomes exercisable if the closing price equals or exceeds $14.40 per share 
occuring prior to April 9, 1999.  In the first quarter of fiscal year 1999, 
this condition was met but pursuant to an additional requirement the warrants 
are not exercisable until April 9, 1999.  The following table sets forth the 
expiration date, number of warrants and the respective exercise prices of 
these warrants.

     At date of grant, the fair value of the warrants was determined at 
$93,000 and is being amortized to expense over the service period.

     (c)  STOCK OPTIONS

     The Company has five stock option plans which provide for the issuance of
options to key employees and directors of the Company.  As of April 30, 1998,
1997 and 1996, the Company had outstanding stock options of 1,308,086, 922,810,
and 841,303, respectively, to purchase shares of common stock.  The following

     For additional disclosures regarding the outstanding preferred stock, the
employee stock options, and the warrants, see Note 7.

     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.   FASB 123:  COMPENSATORY STOCK OPTION PLAN

     The Company has elected to account for its employee stock options under 
Accounting Principles Board Opinion No. 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.  

<PAGE>

                                                                             58

     Statement 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 Company determined this information using the fair value 
method of that Statement.  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:

</TABLE>

     In management's opinion existing stock option valuation models do not 
provide a reliable single measure of the fair value of employee stock options 
that have vesting provisions and are not transferable.  In addition, option 
pricing models require the input of highly subjective assumptions, including 
expected stock price volatility.  For fiscal years 1997 and 1996, the "As 
Adjusted" net income per share has been restated based on refined estimates 
and assumptions.

10.  REVENUES

     During fiscal year 1998, the IMPCO, BV, IMPCO Pty and I.M.P.C.O. 
Mexicano subsidiaries accounted for approximately sixteen percent, ten 
percent and one percent of total consolidated revenues, respectively, and 
contract revenue accounted for approximately twelve percent of consolidated 
revenues.  During fiscal year 1998, General Motors Corporation accounted for 
approximately FIFTEEN percent of consolidated revenues.  During fiscal years 
1997 and 1996, no single unaffiliated customer exceeded ten percent of 
consolidated revenues.

     The Company routinely sells products to a broad base of 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.

11.  SEGMENT DATA

     The Company has U.S. based operating facilities and three foreign based 
operating subsidiaries in Holland (IMPCO BV), Australia (IMPCO Pty) and 
Mexico (I.M.P.C.O. Mexicano).  Transfers between geographic areas include 
inter-company sales, which are eliminated in consolidation.  Operating income 
is total revenue less operating expenses, excluding finance charges and 
taxes.  Information concerning the Company's geographic areas of operation in 
fiscal year 1998 is as follows (dollars in thousands):

12.  CONTRACT REVENUE

     In August 1995, the Company extended its original 1993 two year 
fixed-price contract with General Motors Corporation (GM) to develop, 
manufacture and install compressed natural gas engine management systems (CNG 
systems).  Under the terms of the contract, the Company is engineering, 
testing and validating CNG systems for certain 1997, 1998, and 1999 model 
year car and truck platforms in compliance with GM's specifications.  

     Revenues for development efforts are principally recognized by the 
percentage of completion method and principally related to contracts with GM. 
During fiscal year 1998, 1997, and 1996 GM and other contract revenues 
comprised 12%, 5%, and 6% of the Company's total revenues, respectively.  
Operating income earned on the GM and other development contracts during 
fiscal year 1998, 1997 and 1996 was approximately $1,511,000, $400,000 and 
$155,000 after deducting an allocation for selling, general and 
administrative costs.

13.  PURCHASES

     During fiscal years 1998, 1997 and 1996, purchases from one vendor 
constituted approximately 18%, 17% and 20% of consolidated net inventory 
purchases, respectively.  In fiscal year 1998, 10 suppliers accounted for 
approximately 55% of consolidated net inventory purchases.

14.  SUPPLEMENTARY CASH FLOW INFORMATION

     During fiscal years 1998, 1997 and 1996 the following non-cash 
transactions were effected and are not reflected in the Consolidated 
Statements of Cash Flows:

     a)   The Company incurred capital lease obligations of approximately
          $1,296,000, $835,000 and $700,000, respectively.

     b)   Pursuant to the IMPCO BV acquisition an outstanding debt obligation of
          1,279,000 Dutch Guilders (US $766,000), was converted into a term loan
          during fiscal year 1996.

     c)   Interest and taxes paid during fiscal year 1998, 1997, and 1996 are as
          follows:

16.  OTHER MATTERS

     In July 1998, the Company became aware of a fourth quarter 1997 
transaction that could be in violation of certain U.S. Government export 
regulations.  In July 1997, the Company became aware of a similar transaction 
which also occurred in the fourth quarter of 1997.  In both cases, the 
Company immediately engaged legal counsel to investigate the occurrences, 
assess whether a violation occurred and advise whether disclosure should be 
made to the appropriate governmental authorities.  Following discovery of the 
first fourth quarter 1997 transaction, the Company adopted a compliance 
policy which includes compliance with export licensing and trade sanctions, 
and has taken steps to make employees aware of export regulations.  Also, the 
first transaction was disclosed to the appropriate governmental authorities 
in August of 1997.

     Currently, there are no charges of wrong doing, any pending government 
investigation of the Company's export activities or any other response from 
the governmental authorities to the Company's prior disclosure.  It is the 
opinion of the Company that as a result of its disclosure of the facts to the 
appropriate authorities in both cases, and in light of the facts that the 
products sold were non-sensitive in nature and that the Company has installed 
policies and procedures to prevent future violations of export regulations, 
an ultimate settlement with the government should not have a material adverse 
effect on the Company's financial position, results of operations, or cash 
flows.  However, until the matter is settled with the government, the amount 
of fines, if any, or other sanctions that may be imposed cannot be reasonably 
estimated.
