ITEM 1.  BUSINESS
 
INTRODUCTION
 
    International Rectifier Corporation ("IR" or the "Company") is a major
worldwide supplier of power semiconductors. Power semiconductors switch or
condition electricity at relatively high voltage and current levels in products
such as power supplies, motor controls, computers/peripherals, automobiles,
portable phones, and electronic lighting ballasts.
 
    The Company designs, manufactures, and markets power semiconductors which
are used for power conversion. In a manner similar to the way that oil is
refined to produce gasoline to power a car, electrical power is converted to
operate equipment. This process of power conversion can be viewed in four
stages: input rectification, control, switching, and output rectification. Input
rectification conditions off-line electricity, typically rectifying
alternating-current to direct-current. The control function measures incoming
electricity and sends a signal to a switch. The switch chops the energy into
small elements. Output rectification re-configures the elements into a form
usable by electrically operated equipment.
 
    IR supplies products that perform each of the four basic functions in power
conversion, and many circuits use more than one type of IR product. This allows
IR to develop products that work together to optimize overall circuit
performance, and enables the Company to capitalize more broadly on market-
leading products.
 
    IR's products are used in all major market sectors. Applications for power
semiconductors in automobiles include anti-lock braking and fuel injection
systems, power accessories, and air bags. Computer/peripheral applications
include power supplies, disk drives, and printers. Office equipment applications
include copiers and facsimile machines. Consumer electronics and lighting
applications include home entertainment, household appliances, and electronic
lighting ballasts. Communications applications include portable phones,
telephone networks, and modems. Power semiconductors are also used widely in
industrial applications such as motor-driven production lines, machine tools,
fork lifts, and welders.
 
    Based on statistics published by the Semiconductor Industry Association (the
"SIA"), the Company believes it is the leader in the power MOSFET (Metal Oxide
Semiconductor Field Effect Transistor) segment with its trademarked HEXFET power
MOSFETs and IGBTs (Insulated Gate Bipolar Transistors). SIA data indicates that
industry-wide sales of power MOSFETs were $2.1 billion in calendar 1995, an
increase of 44% over 1994 levels, and that, over the past five years, power
MOSFET sales have grown at an average rate of 29% per year.
 
    The Company's major customers in the automotive segment include Delco, Ford,
Siemens, and Bosch. International Business Machines, Hewlett Packard, and Compaq
purchase the Company's products in the computer segment. Consumer electronics
customers include Philips and Sony. Customers in the telecommunications segment
include Lucent Technologies and Nokia. The Company also sells its products to
distributors including Arrow Electronics and Future Electronics. In fiscal year
1996, the Company's sales by region were approximately 46% from North America,
28% from Europe, and 26% from Asia. IR has manufacturing facilities in North
America, Europe, and Asia, and uses subcontract assembly in Asia.
 
    IR was founded as a California corporation in 1947 and reincorporated in
Delaware in 1979. Its executive offices are located at 233 Kansas Street, El
Segundo, California 90245 and its telephone number is (310) 726-8000.
 
POWER SEMICONDUCTOR INDUSTRY
 
    Semiconductors are silicon-based chips that conduct and block electricity.
The semiconductor industry consists of integrated circuits ("ICs") and power
semiconductors. ICs operate at low power levels and perform multiple functions
to process and convey information in electronic signal form. IC
 
                                       1
<PAGE>
capability is largely defined by circuit density, which increases as its
features are miniaturized. The applications for ICs are generally concentrated
in the computer industry and have been subject to frequent redesign, short
product life cycles and rapid obsolescence. As a result, the demand for ICs has
been highly cyclical.
 
    In contrast to ICs, power semiconductors operate at higher power levels and
perform a single function: they condition and control electricity to operate a
power supply, control a motor, or light a lamp. Their capability is largely
defined by the level of power that they can handle and their efficiency in
converting raw electric current into a more useful form. The amount of electric
current handled and the heat generated limit the rate at which power
semiconductors can be miniaturized.
 
    Advances in power semiconductor performance and cost-per-function have been
achieved through the use of MOS technology. MOS power transistors (power MOSFETs
and IGBTs) have gained an increasing share of the power transistor market at the
expense of bipolar transistors that also serve the switch function.
 
    MOS power transistors offer significant benefits over bipolar power
transistors. They provide much greater switching speed, which allows the design
of higher frequency, more compact circuits. They are activated by voltage rather
than current, so they require less external circuitry. MOS transistors are more
compatible with microprocessor controls. They offer more reliable long-term
performance and are more rugged, so they can better withstand adverse operating
conditions. Power MOSFETs and IGBTs compare favorably to bipolar power
transistors on a price/performance basis.
 
APPLICATIONS
 
    Power semiconductors are used in a broad spectrum of commercial and
industrial applications, including many products with long life cycles. The
Company believes that because of their more gradual rate of technological change
and the diversity of applications, the demand for power semiconductors is less
cyclical than for ICs. Power semiconductor demand is driven by conversion to new
technologies, the proliferation of new end-product applications, and growth in
the end markets. The Company believes that markets driving future demand for
power semiconductors include:
 
    PORTABLE ELECTRONICS.  Advances in power semiconductors help extend battery
life and reduce product size and weight in a variety of battery-operated
products such as lap-top and notebook computers, personal digital organizers,
cellular telephones, household appliances, and hand tools.
 
    AUTOMOTIVE ELECTRONIC SYSTEMS.  The concentration of solid state electronics
in recent model year automobiles has increased rapidly, as safety and comfort
features increase demands on the battery. Applications include anti-lock braking
systems, air-bags, fuel injection systems, electronic power steering, electric
windows, and adjustable mirrors and seats. Adoption of battery operated electric
vehicles to reduce emissions would dramatically increase consumption of MOS
transistors.
 
    ELECTRONIC LIGHTING BALLASTS.  Electronic lighting ballasts, which
incorporate power MOSFETs and Power ICs, significantly reduce the amount of
energy consumed in lighting. Conversion to electronic ballasts has been driven
by lower end-user operating costs and incentives from electric utilities to
encourage energy efficiency.
 
    VARIABLE SPEED MOTORS.  Variable-speed solid state controls increase energy
efficiency and performance in a broad range of industrial and appliance motors.
In addition, clean air legislation is driving the conversion from traditional
chlorofluorocarbons ("CFCs") to less toxic refrigerants which are also less
efficient. Manufacturers of refrigerators and air conditioners can compensate
for these less efficient chemicals by using more efficient variable-speed
motors.
 
PRODUCTS
 
    The Company's products convert electrical power to make it more usable and
efficient in performing work such as operating power supplies, controlling
motors, and lighting lamps. The products'
 
                                       2
<PAGE>
ability to minimize energy lost at each point in the power conversion process is
central to their value. Important growth applications include such
energy-sensitive products as electronic fluorescent lights, more energy
efficient refrigeration and air conditioning equipment, and electric vehicles.
 
    The Company's HEXFET power MOSFET products comprised about 68% of fiscal
1996 sales. IR also supplies IGBT transistors, High Voltage Control ICs,
high-performance diodes, and high power rectifiers and thyristors. The Company
believes that this complete line of power conversion products represents a
competitive advantage, enabling IR to provide customers with integrated
solutions to their power conversion needs.
 
SWITCHING PRODUCTS
 
    MOS TRANSISTORS.  MOS transistors (power MOSFETs and IGBTs) serve the switch
function in power conversion to provide an even, usable flow of power for
electronic equipment.
 
    POWER MOSFETS.  Through its HEXFET product line, the Company is the world
leader in power MOSFETs. The breadth and diversity of the market for these
products help to stabilize demand.
 
    Applications for MOSFETs in automobiles include anti-lock braking and fuel
injection systems, electronic power steering, power accessories, and air bags.
Computer/peripheral applications include power supplies, disk drives, and
printers. Office equipment applications include copiers and facsimile machines.
Consumer electronics applications include home entertainment, video cameras,
household appliances, and power tools. Lighting applications include electronic
lighting ballasts and compact fluorescent bulbs. Industrial applications include
motor control, instrumentation, and test equipment. Communications applications
include telephone networks and modems. Government and aerospace applications
include commercial and military satellites, communications equipment, command-
and-control systems, and missiles.
 
    Market acceptance and brand recognition of HEXFETs have benefited from the
Company's emphasis on quality control and reliability, and the Company believes
its standards to be among the most stringent in the industry. Cumulative and
current data on long and short term product reliability is made available to
customers quarterly.
 
    The Company fabricates the majority of its power MOSFET wafers at HEXFET
America. Die from these wafers are assembled into packaged devices at HEXFET
America, IR's facilities in England and Mexico, and subcontract facilities in
Asia. See "-- Manufacturing."
 
    IGBTS.  IGBTs typically serve the switch function in power conversion
applications that require higher current and voltage than power MOSFETs can
handle efficiently. IGBTs combine the ease of voltage-driven power MOSFET
technology with the conduction efficiency of bipolar transistor technology. The
performance and ruggedness of these devices enable them to replace bipolar
transistors and thyristors in many high-voltage, high-current motor control and
power conditioning applications. Energy-efficient, variable-speed motor controls
are an emerging application, and the Company believes electric vehicles will
require large quantities of IGBTs for each vehicle.
 
    The Company's IGBT technology is closely related to its HEXFET technology,
and the Company views them as complementary products. The Company believes that
its patents on fundamental MOSFET technology also apply to IGBTs, and it is
seeking further patent protection on its IGBT technology.
 
CONTROL PRODUCTS
 
    HIGH VOLTAGE CONTROL ICS.  These devices serve the control function of power
conversion. They perform the functions of several discrete components. This
integration allows IR's customers to simplify circuit design and assembly,
improve reliability and reduce overall system size and cost. In sensing and
responding to adverse operating conditions, High Voltage Control IC performance
is superior to that of discrete components in a safety or diagnostic circuit.
IR's High Voltage Control ICs
 
                                       3
<PAGE>
draw on the Company's MOSFET technology and are designed to optimize the
performance of both power MOSFETs and IGBTs. The Company believes that its power
MOSFET patents also apply to a broad range of High Voltage Control ICs.
 
    High Voltage Control ICs are used in a wide variety of power supply, motor,
and lighting control applications. These include industrial motor controls, home
appliance motor controls, solenoid drivers, welding equipment, telecom
switchers, computer/peripherals, instrumentation and test equipment, electronic
lighting ballasts, and compact fluorescent light bulbs.
 
OUTPUT RECTIFICATION PRODUCTS
 
    The Company's Schottky diodes and Fast-Recovery diodes serve the output
rectification function of power conversion. Output rectification reconfigures
the elements into a form usable by electrically-operated equipment. Schottky
diodes are used with power MOSFETs in high-frequency applications such as
computer/peripherals. The Company's trademarked HEXFRED Fast-Recovery diodes are
used with IGBTs in higher-current, lower-frequency applications such as motor
controls.
 
INPUT RECTIFICATION PRODUCTS
 
    The Company also manufactures a broad line of rectifiers, diodes and
thyristors that serve the input rectification function of power conversion.
These products condition power to make it more efficient and usable, principally
in industrial end products that require power-handling capability from one amp
to 5000 amps and from 20 volts to 5000 volts. Applications include motor and
lighting controls, welding equipment, fork lifts, machine tools, induction
heating, locomotives, motor-driven production lines, smelting equipment, and
power supplies.
 
MANUFACTURING
 
    Semiconductor manufacturing involves two phases of production: wafer
fabrication and assembly (or packaging). Wafer fabrication is a sequence of
process steps that expose silicon wafers to chemicals that change their
electrical properties. The chemicals are applied in patterns that define cells
or circuits within numerous individual devices (often termed "die" or "chips")
on each wafer. Packaging or assembly is the sequence of production steps that
divide the wafer into individual chips and enclose the chips in external
structures (termed packages) that make them usable in a circuit. Power
semiconductors generally use the process technology and equipment already proven
in ICs manufacturing.
 
    The Company has production facilities in California, England, Italy, Mexico,
India, and China. In addition, the Company has equipment at, or manufacturing
supply agreements with, subcontractors located in the Philippines, Japan,
Taiwan, Malaysia, and the United States.
 
    IR fabricates the majority of its power MOSFET wafers at HEXFET America in
Temecula, California. In addition, HEXFET America produces IGBT wafers. A wafer
fabrication facility for IGBTs and other MOSFET devices as well as assembly
operations for government and other advanced products, such as High Voltage
Control ICs, are located in El Segundo, California. Facilities that assemble
HEXFETs and other products are located in the United States and overseas, in
Company-owned and subcontract facilities. In Tijuana, Mexico, the Company
assembles MOSFETs, Schottkys, IGBTs, and other modules. The Company's Oxted,
England facility, which qualifies as a duty-free facility, assembles MOSFETs,
IGBTs, Schottkys, and diodes. Currently, the Company manufactures substantially
all its high power rectifiers and thyristors at its Turin, Italy facility. A
Schottky wafer fabrication facility currently under construction at its Turin
facility is scheduled to be in production by the end of calendar 1996. The
Company also has arrangements with third parties for product assembly in the
Philippines, Malaysia, Taiwan, Japan, and Mexico. In a duty-free zone in India,
the Company has an assembly facility for rectifiers and thyristors.
 
    To aggressively address the fastest growing segments of the power transistor
market: high density MOSFETs and IGBTs, the Company installed a second wafer
fabrication unit at HEXFET America. Phase one, completed in September 1995, is
expected to add about $185 million in additional product shipments at full
utilization. Phase two of the expansion, scheduled to be in production in the
second half of fiscal year 1997, is expected to support an additional $150
million in annual revenues at
 
                                       4
<PAGE>
an incremental cost of approximately $45 million. Estimated additional annual
revenues from the expansion are based on fiscal year 1996 pricing levels.
Next-generation devices designed for production in the new fabrication unit
incorporate design and process advancements in the Company's proprietary HEXFET
and IGBT technologies. A core process with shared elements for both products
enables the unit to combine flexibility with efficient high-volume manufacturing
techniques. Fabrication is performed on six-inch wafers and uses a
continuous-flow layout similar to the one already in use at HEXFET America.
 
    The Company is transferring its assembly lines from HEXFET America to its
assembly facility in Tijuana, Mexico and to independent subcontractors. The move
affects only the assembly phase of manufacturing and allows the California plant
to focus on expansion of its benchmark wafer fabrication capability and enables
the Company to reduce the cost of assembling its HEXFET-Registered Trademark-
power MOSFET chips into finished devices. Currently, the transfer is
approximately 60% complete. The move is targeted for completion in the second
half of fiscal year 1997.
 
MARKETING, SALES, AND DISTRIBUTION
 
    The Company markets its products through sales staff, representatives, and
distributors. The Company believes its ability to offer products that serve each
of the four functions of power conversion enhances its competitive position in
the overall power semiconductor market.
 
    In fiscal year 1996, the Company's sales by region were approximately 46%
from North America, 28% from Europe, and 26% from Asia. The Company's domestic
direct sales force is organized in four sales zones. In Western Europe, the
Company's products are sold through its own sales force as well as through sales
agents and distributors. The Company's European sales and representative offices
are in England, Italy, Sweden, France, Germany, Finland, Denmark, Switzerland,
Russia, the Czech Republic, and Hungary. In Asia, IR has sales, representative,
and liaison offices in India, Japan, Singapore, China, Hong Kong, and South
Korea.
 
    Because many applications require products from several product groups, the
Company has organized its marketing efforts by market sector, rather than
product type. These business management groups focus on several key commercial
sectors and on government and aerospace business. In addition, the Company's
staff of application engineers provides customers with technical advice and
support regarding the use of IR's products.
 
CUSTOMERS
 
    In most cases, the Company's devices are incorporated in larger systems
manufactured by end product manufacturers. The Company's customers in the
automotive segment include Delco, Ford, Siemens, and Bosch. International
Business Machines, Hewlett Packard, and Compaq purchase the Company's products
in the computer segment. Consumer electronics customers include Philips and
Sony. Customers in the telecommunications segment include Lucent Technologies
and Nokia. Approximately 30% of the Company's revenues come from sales of its
products to distributors including Arrow Electronics and Future Electronics. The
Company has historically found it more difficult to determine distributor demand
than demand from its other customers.
 
BACKLOG
 
    As of June 30, 1996, the Company's backlog of orders was $315.5 million
compared to $210.8 million as of June 30, 1995. Backlog is comprised of purchase
orders and customer forecast commitments scheduled to be shipped within the
following 12 months. Increasingly, major customers are operating their
businesses with shorter lead times and are placing orders on a periodic rather
than an annual basis. In most circumstances IR allows customers to cancel
purchase orders without penalty. Backlog is not necessarily indicative of sales
for any future period.
 
    Subsequent to year-end, the Company noted aggressive efforts by distributors
(which accounted for approximately 30% of the Company's revenues in fiscal 1996)
to reduce inventory levels, including order cancellations and a slow-down in new
order input, which have cut deeply into the Company's backlog. Furthermore,
competitive price moves have resulted in a 10% to 15% decrease in average
 
                                       5
<PAGE>
prices on approximately one-third of the Company's business. The Company
anticipates that the inventory correction should be largely completed by the end
of December 1996. In addition, the Company believes the competitive pressure may
result in lower prices on a significant portion of its business.
 
RESEARCH AND DEVELOPMENT
 
    The Company's breadth of technology and focus on power conversion underlie
an integrated approach to developing complementary products that add value and
differentiate International Rectifier from its competitors. IR conducts research
and development activities to improve the price/ performance ratio of its
product offerings to customers across a wide range of end-use applications.
 
    In fiscal years 1996, 1995, and 1994, the Company spent approximately $27.0
million, $20.1 million, and $16.4 million, respectively, on research and
development activities.
 
    In fiscal 1995, the Company introduced a new generation of
HEXFET-Registered Trademark- brand power MOSFETs that offer benchmark
performance and manufacturing cost reductions designed to create a significant
competitive advantage. The Generation5 HEXFETs are being produced at the
Company's newest wafer fabrication unit in Temecula, California, which also
produces IR's latest generation of IGBT transistors using the same core process.
 
    In fiscal 1996, IR also previewed its most comprehensive offering to date in
the area of "solution" products that combine multiple components and
technologies to benefit customers' overall circuit size, cost, and performance.
These products have been in beta site testing since March 1996 and are scheduled
for market introduction in late calendar 1996.
 
INTELLECTUAL PROPERTY
 
    The Company has made significant investments in developing and protecting
its intellectual property. Through successful enforcement of its patents, the
Company has entered into a number of license agreements, generated royalty
income and received substantial payments in settlement of litigation. The
Company currently has 80 unexpired U.S. patents and 47 U.S. patents pending.
Those patents fundamental to the Company's products expire between 2000 and
2010. In addition, the Company has 61 foreign patents and 154 foreign patents
pending in a number of countries. The Company is also licensed to use certain
patents owned by others. Under the terms of an agreement with Unitrode
Corporation that terminates in March 2000, the Company pays Unitrode
approximately 12% of the Company's net patent royalty income. The Company has
several registered trademarks in the United States and abroad including
trademarks for HEXFET. The Company believes that its proprietary technology and
intellectual property contribute to its competitive advantage.
 
    Since the Company believes that its power MOSFET patents are broadly
applicable, it is committed to enforcing its rights under those patents and is
pursuing additional license agreements. The Company presently has license
agreements with 18 companies: ABB Semiconductor, Inc.; CP Clare Corporation;
Harris Corporation; Hitachi, Ltd.; Matsushita Electronics Corporation;
Mitsubishi Electric Corporation; Motorola, Inc.; National Semiconductor
Corporation; NEC Corporation; Nihon Inter Electronics Corporation; Philips
Electronics, N.V.; Sanken Electric Company, Ltd.; Sanyo Electric Company;
SGS-Thomson Microelectronics, Inc.; Siemens Aktiengesellschaft; Siliconix
incorporated; Toshiba Corporation; and Unitrode Corporation. In fiscal 1996,
$16,262,000 of revenues were derived from royalty-bearing license agreements.
 
    Certain of the Company's fundamental power MOSFET patents have been
subjected, and continue to be subjected, to reexamination in the United States
Patent and Trademark Office ("PTO"). The patents subject to reexamination are
fundamental to the Company's MOS transistors and their loss would allow
competitors to use currently patented features of the Company's MOS transistor
technology without liability for infringement of those patents. On the following
dates, the PTO granted requests for reexamination of the following patents of
the Company: November 13, 1992 and September 12, 1994 on patent 4,642,666;
October 13, 1993 on patent 4,705,759; September 12, 1994 on patent 4,959,699;
September 23, 1994 and June 28, 1995 on patent 5,008,725; January 17, 1995 on
 
                                       6
<PAGE>
patent 5,130,767; June 5, 1995 on patent 5,191,396; and June 14, 1995 on patent
4,593,302. On February 14, 1995 and on December 26, 1995, respectively, the PTO
issued reexamination certificates, confirming the patentability of the Company's
U.S. patents 4,705,759 and 5,191,396.
 
    Although no assurance can be given as to the ultimate outcome of the
Company's patent enforcement efforts, the PTO reexamination proceedings, or the
success of the Company's patent licensing program, the Company believes that its
patent portfolio will be the source of continuing royalty income.
 
COMPETITION
 
    The Company encounters differing degrees of competition for its various
products, depending upon the nature of the product and the particular market
served. Generally, the semiconductor industry is highly competitive and subject
to rapid price changes, and many of the Company's competitors are larger
companies with greater financial resources than IR. The Company believes that
its breadth of product line and its ability to combine products that serve the
different functions into one package distinguish it from its competitors. IR's
products compete with products manufactured by others based on breadth of
product line, quality, price, reliability, over-all performance of the products,
delivery time to the customer, and service (including technical advice and
support). The Company's competitors include Eupec, Harris Corporation, Hitachi
Ltd., Motorola, Inc., NEC Corporation, Philips International B.V., Powerex,
Inc., Samsung Semiconductor Inc., SGS-Thomson Microelectronics, Siemens AG,
Siliconix incorporated, Toshiba Corporation, and Westcode Semiconductors Ltd.
 
ENVIRONMENTAL MATTERS
 
    Federal, state, and local laws and regulations impose various restrictions
and controls on the discharge of certain materials, chemicals, and gases used in
semiconductor processing. The Company does not believe that compliance with such
laws and regulations will have a material adverse effect on its financial
position.
 
    The Company and Rachelle Laboratories, Inc. ("Rachelle"), its former
pharmaceutical subsidiary which discontinued operations in 1986, have been named
among several hundred entities as potentially responsible parties ("PRPs") under
the provisions of the Comprehensive Environmental Response, Compensation and
Liability Act of 1980 ("CERCLA"), in connection with the United States
Environmental Protection Agency's ("EPA") investigation of the disposal of
allegedly hazardous substances at a major superfund site in Monterey Park,
California (the "OII Site"). Certain PRPs who settled certain claims with the
EPA under consent decrees filed suit in Federal Court in May 1992 against a
number of other PRPs, including the Company, for cost recovery and contribution
under CERCLA. The lawsuit against the Company, relating to the first and second
consent decrees, was settled in August 1993 for the sum of $40,000 to avoid
protracted and expensive litigation. In June 1995, the Company was named among
others as a party defendant in Federal Court apparently in connection with a
third consent decree with respect to the OII Site. The Company received a letter
(dated July 25, 1995) from the U.S. Department of Justice offering to settle
claims against Rachelle relating to the first three elements of clean-up work at
the OII Site for the sum of $4,953,148 (the final remedy assessment has not yet
been made). This settlement offer expired by its terms on September 1, 1995. The
Company also received a separate letter from the EPA dated July 25, 1995, with
respect to International Rectifier only, notifying the Company that it may
qualify for a settlement with de minimis generators under CERCLA Section 122(g).
The Company has received no further communications in this regard. At an August
17, 1995 meeting with EPA representatives and representatives of other PRPs, EPA
representatives stated that they will not have an estimate of the cost of final
clean-up until at least early 1996. The Company is unaware of any estimate of
the cost of final clean-up of the site.
 
    On August 7, 1995, the Company received a Supplemental Information Request
from the EPA, directed to Rachelle. In its response, dated October 20, 1995, the
Company explained that none of the wastes generated by Rachelle were hazardous.
The Company has received no further communications in connection with the
Supplemental Information Request.
 
                                       7
<PAGE>
    Claims have been made with the Company's insurers with respect to the OII
site matter; however, there can be no assurance that the insurance coverage
attaches to these claims. The Company does not believe that either it or
Rachelle is responsible for the disposal at the OII site of any material
constituting hazardous substances under CERCLA. Although the ultimate resolution
of this matter is unknown, the Company believes that it will not have a material
adverse impact on its financial position.
 
    In May 1993, the Company purchased property from its Employee Profit Sharing
and Retirement Plan. It was determined that the property required clean-up of
seepage from a storage tank, at an estimated additional cost of $525,000. The
Company commenced the clean-up in fiscal year 1994, and through June 30, 1996
approximately $518,000 in clean-up costs have been incurred which will be
capitalized as additional costs of the property.
 
    On July 18, 1994, the Company received a letter from the State of Washington
Department of Ecology (the "Department") notifying the Company of a proposed
finding that the Company is a potentially liable person ("PLP") for alleged PCE
contamination (also known as perchloroethylene, tetrachloroethylene, and other
names) of real property and groundwater in Yakima County, Washington. The letter
alleges that the Company arranged for disposal or treatment of the PCE or
arranged with a transporter for the disposal or treatment of the PCE in Yakima
County. The Company replied by a letter dated August 11, 1994, stating that it
has not contributed to PCE or other solvent contamination at the Yakima County
site (resulting from sending carbon canisters for regeneration to a facility in
the county) and that it should not be designated a PLP. On October 11, 1994, the
Company received a letter from the Department notifying the Company of its
finding that the Company is a PLP in the above matter. On June 20, 1996, the
Company received a letter from the Washington Department of Ecology, stating
that a settlement offer would be extended to all potentially liable persons in
late summer or early fall of 1996. While the letter did not commit to the amount
of any settlement, it predicted a settlement of approximately $4.95 for each
pound of carbon sent to Cameron-Yakima.
 
    The Company received a letter dated September 9, 1994, from the State of
California Department of Toxic Substances Control stating that the Company may
be a PRP for the deposit of hazardous substances at a facility in Whittier,
California. The Company, in June 1995, agreed to join a group of other PRPs to
remove contamination from the site. The group currently estimates the total cost
of the clean-up to be between $3.1 million and $4 million, of which between
$12,000 and $15,000 is presently expected to be allocated to the Company.
However, the ultimate cost borne by the Company will depend on the extent of the
clean-up undertaken by the group and the actual clean-up costs and the final
allocation scheme agreed upon by the group.
 
EMPLOYEES
 
    As of June 30, 1996, the Company employed approximately 3,915 people, of
whom approximately 2,775 are employed in North America, 1,065 in Western Europe,
and 75 in Asia. The Company is not a party to any collective bargaining
agreements. The Company considers its relations with its employees to be good.
 
ITEM 2.  PROPERTIES
 
    The Company's operations occupy a total of approximately 1,035,000 square
feet, of which approximately 564,000 square feet are located within the United
States. Of the worldwide total, approximately 346,000 square feet are leased and
the balance is owned by the Company.
 
    IR's leases expire between 1996 and 2012. If the Company is unable to renew
these leases upon expiration, it believes that it could find other suitable
premises without any material adverse impact on its operations.

(1) In May 1995 the Company purchased land in Tijuana, Mexico to construct a new
    assembly facility. At June 30, 1996, the building was substantially
    complete. The move from the leased facilities is scheduled for August 1996
    through February 1997.
 
    The Company believes that these facilities are adequate for its current and
anticipated near term operating needs. IR estimates that it currently utilizes
approximately 80% of its worldwide manufacturing capacity.
 
    The Company has sales and technical support offices located throughout the
United States, Canada, France, Germany, Finland, Scandinavia, Russia, Czech
Republic, Hungary, Hong Kong, Japan, China, Korea, Singapore, and India which
operate in leased facilities.
 
ITEM 3.  LEGAL PROCEEDINGS
 
    The Company and SGS-Thomson Microelectronics, Inc. ("SGS") are engaged in
various legal proceedings relating to their respective power MOSFET patents. SGS
filed suit against the Company in June 1991 in Federal District Court in Texas,
charging infringement of U.S. patent 4,553,314. On motion by the Company, the
suit was transferred to the Federal District Court in Los Angeles, California,
and thereafter SGS amended its complaint to charge infringement of U.S. patents
4,495,513 and 4,712,127. SGS alleges, in substance, that the Company's power
MOSFET, power IC and IGBT products infringe the '314 patent, that the Company's
IGBT products infringe the '513 patent, and that certain packages for the
Company's products (including certain power MOSFET packages) infringe the '127
patent. The complaint, as amended, seeks unspecified actual damages (but no less
than an unspecified reasonable royalty) and an injunction restraining further
sales of such products. On February 1, 1993, the District Court dismissed SGS's
claims for infringement of the '127 and '513 patents for lack of standing and on
March 15, 1993, ruled that the SGS '314 patent is unenforceable due to
inequitable conduct. SGS appealed these rulings, as well as the order
transferring the case to California, to the Court of Appeals for the Federal
Circuit. The Company cross-appealed a separate ruling by the District Court
denying the Company's motion for summary judgment that the '314 patent is
invalid. In July 1994, the Federal Circuit vacated the District Court's grants
of summary judgment as to the '513, '127, and '314 patents and affirmed the
District Court's denial of the Company's motion for summary judgment of
invalidity of the '314 patent. The Federal Circuit ordered, however, that the
case should proceed in California. On July 5, 1995, the Court, based on the
stipulation of the parties, effectively stayed SGS's claims on its '314 and '127
patents pending the outcome of reexamination of the patentability of the subject
matter of those patents by the PTO. These reexamination proceedings are still
pending.
 
    In November and December 1995, the parties presented testimony and evidence
to the District Court concerning the interpretation of the claims of the '513
patent; the Court has not yet ruled on the matter.
 
    The Company has also filed a separate action in the same District Court
against SGS and its Italian affiliate, SGS-Thomson Microelectronics, S.r.l.,
seeking an injunction against infringement of the Company's U.S. patents
5,008,725 and 5,130,767. This action has been essentially stayed pending
completion of reexamination of these patents by the PTO (see "Intellectual
Property").
 
                                       9
<PAGE>
    The Company filed another separate action in the same District Court on
August 13, 1996, against the same SGS entities charging infringement of its U.S.
patent 5,545,955.
 
    In the Fall of 1995, SGS and SGS-Thomson Microelectronics, S.A.
("SGS-France") commenced an infringement action in Great Britain against the
Company and International Rectifier (Great Britain) Limited ("IRGB") based on
the European counterpart patent to the '513 patent (European Patent (UK) No.
0,068,546). The Company and IRGB have filed a response denying the material
allegations plead by SGS and SGS-France and seek revocation of the foreign
counterpart patents at issue. The British action is set for trial in July 1997.
 
    The Company, its directors, and certain officers have been named as
defendants in three class action lawsuits filed in Federal Court in California.
These suits seek unspecified but substantial compensatory and punitive damages
for alleged intentional and negligent misrepresentations and violations of the
federal securities laws. The complaints generally allege that the Company and
the other defendants made materially false statements or omitted to state
material facts in connection with the public offering of the Company's common
stock completed in April 1991 and the redemption and conversion in June 1991 of
the Company's 9% Convertible Subordinated Debentures Due 2010. They also allege
that the Company's projections for growth in fiscal 1992 were materially
misleading. Although the Company believes that the claims alleged in the suits
are without merit, the ultimate outcome cannot be presently determined. A
substantial judgment or settlement, if any, could have a material adverse effect
on the Company's financial condition and results of operations. Two of these
suits also name Kidder, Peabody & Co. Incorporated and Montgomery Securities as
defendants. Defendants Kidder, Peabody & Co. and Montgomery Securities have
demanded that the Company indemnify them for any liability or expenses,
including attorneys fees, that they may incur in connection with this
litigation. Those defendant underwriters base that demand on their underwriting
agreements with the Company. The Company has agreed to advance the underwriter
defendants' attorneys fees pursuant to that indemnity, subject to a reservation
of the Company's right to seek reimbursement of those advances.
 
    No provision for any liability that may result upon adjudication of these
matters has been made in the consolidated financial statements.

1996 COMPARED WITH 1995
 
    Revenues for fiscal 1996 increased 34.5% to $576.8 million from $429.0
million in the prior year. The Company's revenue increase reflected continued
growing demand for the Company's power MOSFET and related devices which resulted
in a 39% increase in revenues from these products. Revenues from the thyristor
and rectifier product lines increased 6% from the prior period. Changes in
foreign exchange rates negatively impacted revenues by approximately $3.8
million. Revenues for fiscal 1996 also included $16.3 million of net patent
royalties compared to $9.7 million in the prior period.
 
    Gross profit was 39.1% of revenues ($225.8 million) in fiscal 1996 versus
35.2% of revenues ($150.8 million) in fiscal 1995. The increased margin
reflected greater manufacturing volume and efficiencies and a greater
contribution from new higher margin products.
 
    In fiscal 1996, selling and administrative expense was 17.7% of revenues
($102.1 million) versus 19.2% of revenues ($82.3 million) in fiscal 1995. The
planned increase in absolute dollars was made to support the Company's 34.5%
revenue growth and consisted mainly of costs related to additional staffing,
higher commission expense, and increased advertising expense.
 
    In fiscal 1996, the Company's research and development expenditures
increased $6.9 million to $27.0 million (4.7% of revenues) from $20.1 million
(4.7% of revenues) in the prior period. Research and development activities were
focused on the advancement and diversification of the HEXFET product line and
expansion of the related IGBT products, the development of High Voltage Control
ICs and complementary components that work in combination with HEXFETs and IGBTs
to improve system performance.
 
    Net interest expense and net other expense were essentially unchanged in
fiscal 1996 from fiscal 1995.
 
1995 COMPARED WITH 1994
 
    Revenues for fiscal 1995 increased 30.4% to $429.0 million from $328.9
million in the prior year. The Company's revenue increase reflected continued
growing demand for the Company's power MOSFET and related devices which resulted
in a 34% increase in revenues from these products. Revenues from the thyristor
and rectifier product lines increased 17% from the prior period. Changes
 
                                       14
<PAGE>
in foreign exchange rates positively impacted revenues by approximately $11.1
million. Revenues for fiscal 1995 also included $9.7 million of net patent
royalties compared to $9.0 million in the prior period.
 
    Gross profit was 35.2% of revenues ($150.8 million) in fiscal 1995 versus
33.1% of revenues ($108.9 million) in fiscal 1994. The increased margin
reflected greater manufacturing volume and efficiencies and a greater
contribution from new higher margin products.
 
    In fiscal 1995, selling and administrative expense was 19.2% of revenues
($82.3 million) versus 21.0% of revenues ($69.0 million) in fiscal 1994. The
decreased percentage reflects the Company's continued commitment to reducing
operating expenses as a percentage of revenues.
 
    In fiscal 1995, the Company's research and development expenditures
increased $3.7 million to $20.1 million (4.7% of revenues) from $16.4 million
(5.0% of revenues) in the prior period. The Company's research and development
program was focused on the advancement and diversification of the HEXFET product
line and expansion of the related IGBT products, the development of High Voltage
Control ICs and power products that work in combination with HEXFETs and IGBTs
to improve system performance.
 
    The major components of other expense include a $1.0 million charge for the
transfer of assembly operations to the Company's Mexican subsidiary, $0.3
million of severance costs, $0.3 million on the disposal of property, plant and
equipment, $0.3 million of local taxes and $0.5 million in legal fees, offset by
$0.3 million in foreign currency transaction gains and $1.8 million of net
patent royalty revenues related to prior years.
 
    In fiscal 1995, net interest expense decreased by $3.2 million from the
prior year. The decrease was due to approximately $2.4 million in interest
income earned in the current year on funds received from a November 1994
offering of the Company's common stock and an increase of $1.7 million of
interest capitalized in the current year, partially offset by increased interest
expense in the first half of the year on higher average debt balances over the
prior year.
 
SEASONALITY
 
    The Company has experienced moderate seasonality in its business in recent
years. On average over the past three years, the Company has reported
approximately 46% of annual revenues in the first half and 54% in the second
half of its fiscal year.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At June 30, 1996, the Company maintained cash and cash equivalent balances
of $35.8 million and $18.0 million of short-term investments. Cash in excess of
operating requirements is maintained in the United States. In addition, the
Company had established $71.0 million of domestic and foreign revolving lines of
credit, against which $13.3 million had been borrowed. Based on covenant and
collateral limitations, the Company had an additional $49.5 million available
for borrowing against these lines at June 30, 1996. The Company also had
available $65.0 million of bank term loan facilities and $22.5 million of credit
lines for capital equipment. At June 30, 1996, the Company had made purchase
commitments for capital equipment of approximately $42.9 million.
 
    During fiscal 1997, the Company plans to spend approximately $120 million on
capital expenditures for the continuing expansion of its global wafer
fabrication and assembly capacity. The Company intends to fund these capital
expenditures and working capital requirements through cash and cash equivalents
on hand, anticipated cash flow from operations, and as needed, from funds
available from revolving credit, term loan and equipment financing facilities.
The Company may also consider the use of funds from other external sources
including, but not limited to, public or private offerings of debt or equity.
The Company believes that its existing manufacturing capacity is adequate to
respond to anticipated increases in customer requirements and that planned
capital expenditures of $120 million in fiscal 1997 are consistent with the
Company's view of market needs over the next couple of years.
 
                                       15
<PAGE>
    Although the Company believes that the class action lawsuits brought against
the Company and its Board of Directors (see "Legal Proceedings") are without
merit, the ultimate outcome thereof cannot be presently determined. Accordingly,
the Company has not made any provision for any liability, if any, that may
result upon adjudication of these matters. For the possible effects of
environmental matters on liquidity, see "Business -- Environmental Matters."
 
FOREIGN CURRENCY TRANSACTIONS
 
    Due to the global nature of its operations, the Company is subject to the
effect of international currency fluctuations. In fiscal year 1996, over 50% of
the Company's revenues were derived from sales in foreign markets. In the years
ended June 30, 1996, 1995, and 1994, the Company recognized net foreign currency
transaction gains of $126,000, $347,000, and $376,000, respectively.
 
    The Company manages potential foreign currency exposure by entering into
forward contracts and currency options. These contracts are not speculative in
nature, as the resulting gains or losses will offset any losses or gains on the
underlying hedged transactions.
 
INCOME TAXES
 
    Reflecting benefits derived from the utilization of state and foreign tax
credits and a foreign sales corporation, the Company's effective tax rate in
fiscal 1996 was approximately 30.7%. Partially offsetting these benefits was the
effect of higher statutory tax rates in certain foreign jurisdictions. The
difference between the U.S. federal statutory tax rate of 35% and the Company's
effective tax rates of approximately 17.0% and 16.7% in fiscal years 1995 and
1994, respectively, was attributable mainly to the utilization of U.S. federal
income tax net operating loss carryovers, which were fully utilized in fiscal
1995.
 
SHAREHOLDER RIGHTS PLAN
 
    On August 2, 1996, the Company's Board of Directors adopted a Shareholder
Rights Plan (the "Plan") under which preferred stock purchase rights (the
"Rights") will be granted for each outstanding share of the Company's common
stock held at the close of business on August 14, 1996. The Plan is intended to
ensure fair and equitable treatment for all shareholders in the event of
unsolicited attempts to acquire the Company.
 
    The Rights will become exercisable ten days after a person or group (the
"Acquiror") has acquired beneficial ownership of 20% or more of the Company's
common stock other than pursuant to a qualified offer, or announces or commences
a tender offer or exchange offer that could result in the acquisition of
beneficial ownership of 20% or more. Once exercisable, each Right entitles the
holder to purchase one one-thousandth of a share of a new series of preferred
stock at an exercise price of $135, subject to adjustment to prevent dilution.
If the Acquiror acquires 20% or more of the Company's common stock, each Right
(except those held by the Acquiror) entitles the holder to purchase either the
Company's stock or stock in the merged entity at half of market value. The
Rights have no voting power, expire on August 14, 2006, and may be redeemed at a
price of $0.01 per Right up to and including the tenth business day after a
public announcement that 20% or more of the Company's shares have been acquired
by the Acquiror.
 
    For additional information, refer to the Company's reports to the Securities
and Exchange Commission on Forms 8-K and 8-A filed on August 20, 1996 and August
21, 1996, respectively.
 
CURRENT MARKET CONDITIONS
 
    Subsequent to year-end, the Company noted aggressive efforts by distributors
(which accounted for approximately 30% of the Company's revenues in fiscal 1996)
to reduce inventory levels, including order cancellations and a slow-down in new
order input, which have cut deeply into the Company's backlog. Furthermore,
competitive price moves have resulted in a 10% to 15% decrease in average prices
on approximately one-third of the Company's business. Due to the inventory
correction and price pressures, the Company expects revenues in the first
quarter of fiscal 1997 of between $115 million to $125 million. The reduced
level of shipments will result in a lower gross margin percentage and a higher
level of operating expenses as a percentage of revenues. The Company anticipates
that
 
                                       16
<PAGE>
the inventory correction should be largely completed by the end of December
1996. In addition, the Company believes the competitive pressure may result in
lower prices on a significant portion of its business.
 
    The Company is deferring non-critical hiring and expenditures until a
decisive improvement in business conditions is seen.
 
CAUTIONARY STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995
 
    This Form 10-K Report contains statements which are not historical facts but
are forward-looking statements as that term is defined in the Private Securities
Litigation Reform Act of 1995 and that can be identified by the use of
forward-looking terminology such as "anticipate," "believe," "estimate,"
"expect," "may," "should," "view," or "will" or the negative or other variations
thereof. Such forward-looking statements are subject to risks and uncertainties
which could cause actual results to differ materially from those projected.
Financial results are to a large extent dependent on the power MOSFET segment of
the power semiconductor industry. If market demand does not continue to grow,
revenue growth may be impacted, capacity installed might be under-utilized,
capital spending may be slowed, and Company performance may be negatively
impacted. Other risks and uncertainties which could negatively impact Company
results include: risk of nonpayment of accounts receivable; risk of inventory
obsolescence due to shifts in market demand; push-out of delivery dates and
product returns; acceptance of new products and price pressures; market
acceptance of rival products; risks associated with foreign operations and
foreign currency fluctuations; litigation involving intellectual property;
environmental matters; shareholder lawsuits; and business and general economic
conditions in major markets around the world.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Stockholders and Board of Directors
International Rectifier Corporation
 
    We have audited the accompanying consolidated financial statements and the
financial statement schedule of International Rectifier Corporation and
Subsidiaries as of June 30, 1996 and 1995, and for the fiscal years ended June
30, 1996, 1995, and 1994 as listed on the index on page 17 of this Form 10-K.
These financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and financial statement 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 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of International
Rectifier Corporation and Subsidiaries at June 30, 1996 and 1995, and the
consolidated results of their operations and their cash flows for the fiscal
years ended June 30, 1996, 1995, and 1994, in conformity with generally accepted
accounting principles. In addition, in our opinion, the financial statement

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BUSINESS
 
    International Rectifier Corporation ("IR" or the "Company") designs,
manufactures, and markets power semiconductors which switch or condition
electricity at relatively high voltage and current levels. The Company's
products are used in major market sectors including automobiles, computer/
peripherals, office equipment, consumer electronics, lighting, communications,
and industrial.
 
    IR was founded as a California corporation in 1947 and reincorporated in
Delaware in 1979.
 
    PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of the Company
and all its majority-owned subsidiaries which are located in Europe, Mexico,
Canada, the Far East, and South East Asia. All material intercompany
transactions have been eliminated.
 
    FISCAL YEAR
 
    Fiscal years 1996, 1995, and 1994 consist of 52 weeks ending June 30, July
2, and July 3, respectively. For convenience, all references herein to fiscal
years are to fiscal years ended June 30.
 
    REVENUE RECOGNITION
 
    The Company recognizes revenues from product sales to all customers,
including distributors, at the time of shipment.
 
    FOREIGN CURRENCY TRANSLATION
 
    The financial position and results of operations of the Company's foreign
subsidiaries are measured using the local currency as the functional currency.
Foreign assets and liabilities in the consolidated balance sheet have been
translated at the rate of exchange on the balance sheet date. Revenues and
expenses are translated at the average exchange rate for the year. Unrealized
translation adjustments do not affect the results of operations and are reported
as a separate component of stockholders' equity. In fiscal 1996, 1995, and 1994,
the Company recognized foreign currency transaction gains of $126,000, $347,000,
and $376,000, respectively.
 
    RESEARCH AND DEVELOPMENT
 
    Research and development costs are expensed as incurred.
 
    ADVERTISING
 
    The Company reports the costs of all advertising as expenses in the periods
in which those costs are incurred. The Company shares portions of certain
distributors' advertising expenses through cooperative advertising arrangements.
 
    INCOME TAXES
 
    Deferred income taxes are determined based on the difference between the
financial reporting and tax bases of assets and liabilities using enacted rates
in effect during the year in which the differences are expected to reverse.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amount expected to be realized. Income tax expense is the tax
payable for the period and the change during the period in deferred tax assets
and liabilities.
 
    U.S. income taxes have not been provided on approximately $24,236,000 of
undistributed earnings of foreign subsidiaries since management considers these
earnings to be invested indefinitely or substantially offset by foreign tax
credits.

1.  BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    STOCK SPLIT
 
    On November 20, 1995, the Board of Directors declared a two-for-one split of
the Company's common stock. Shares were distributed on December 22, 1995 to
stockholders of record on December 1, 1995. Stockholders' equity has been
retroactively restated for all periods presented by reclassifying from capital
contributed in excess of par value of shares to common shares the par value of
the additional shares arising from the split. In addition, all references in the
financial statements to number of shares, per share amounts, stock option data,
and market prices of the Company's common stock have been restated to reflect
the split.
 
    EARNINGS PER SHARE
 
    Earnings per share is computed by dividing earnings by the weighted average
number of common and common stock equivalents outstanding. Stock options
outstanding under stock option plans are considered common stock equivalents.
Common stock equivalents for stock options of 807,679, 486,112, and 225,400 were
utilized in the computation of earnings per share in 1996, 1995, and 1994
respectively.
 
    STATEMENT OF CASH FLOWS
 
    The Company invests excess cash from operations in investment grade money
market instruments. The Company considers all highly liquid debt instruments
with a purchased maturity of three months or less to be cash equivalents.
Components in the change in working capital for the fiscal years ended June 30,
1996, 1995, and 1994 were comprised of the following (000's):

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1.  BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    CONCENTRATION OF RISK
 
    The Company places its temporary cash investments with high credit quality
financial institutions. At times, such investments may be in excess of insured
limits.
 
    The Company performs periodic credit evaluations of its customers' financial
condition and generally does not require collateral. Receivables on average are
due in 60 days. Credit losses have consistently been within management's
expectations.
 
    FINANCIAL INSTRUMENTS
 
    The Company operates internationally, giving rise to exposure to market
risks from changes in foreign exchange rates. The Company enters into forward
foreign contracts and foreign currency options to hedge certain foreign currency
denominated receivables and payables from its foreign subsidiaries. The related
gains and losses on these contracts are included in "Other income (expense)."
The Company does not hold or issue financial instruments for trading purposes.
 
    Forward contracts outstanding at June 30, 1996 had maturities of less than
three months and were denominated in Japanese Yen, British Pound Sterling, and
French Francs. Counterparties to the transactions were large financial
institutions. At June 30, 1996, the Company had $22.6 million outstanding in
forward contracts and had no outstanding foreign currency options.
 
    ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at 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.
 
    RECENT ACCOUNTING PRONOUNCEMENTS
 
    In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121 "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of."
This statement will be effective for the Company's year ending June 30, 1997.
SFAS No. 121 requires that long-lived assets and certain identifiable
intangibles held and used by an entity be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable by using the future undiscounted cash flows expected from
the use of the eventual disposition of the asset. Management anticipates
implementing SFAS No. 121 effective July 1, 1996 and believes implementation
will not have a material impact on the Company's financial position, results of
operations, or cash flows.
 
    In October 1995, FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation," which will be effective for the Company's year ending June 30,
1997. SFAS No. 123 provides alternative accounting treatment to Accounting
Principles Board Opinion No. 25 with respect to stock-based compensation and
requires certain additional disclosures, including disclosures if the Company
elects not to adopt the accounting measurement requirements of SFAS No. 123. The
Company does not intend to adopt the accounting measurement requirements of SFAS
No. 123 for stock options granted to employees and therefore in future years
will provide the required additional disclosures in the notes to the
consolidated financial statements.
 
    RECLASSIFICATION
 
    Certain reclassifications have been made to previously reported amounts to
conform with the current year presentation.

2.  BANK LOANS AND LONG-TERM DEBT
    In February 1996, the Company renewed and modified its existing $5 million
unsecured credit facility from Sanwa Bank California. The expiration date was
extended to October 31, 1997, and the interest rate for loans drawn under this
facility was reduced to the bank's cost of funds plus 0.75%, or LIBOR plus
0.75%. In May 1996, the Company extended and modified its existing $25 million
unsecured credit facility with Wells Fargo Bank, N.A. The expiration date was
extended to October 30, 2000, and the interest rate for loans drawn under this
facility was reduced to LIBOR plus 0.75%. In June 1996, the Company renewed its
$10 million unsecured credit facility with Nationsbank of Texas, N.A. The
expiration date of this facility was extended to June 5, 1997 and the interest
rate for loans drawn under this facility was reduced to LIBOR plus 0.75%. These
facilities all contain the same financial covenants and ratios which affect the
availability of funds and prohibit the Company from paying cash dividends. As of
June 30, 1996, no borrowings were outstanding under these three facilities.
 
    The Company has an additional $31.0 million of revolving credit facilities
at foreign locations. The interest rates on borrowings from these facilities
range from 1.5% to 10.75% at June 30, 1996. Under the terms of the agreements,
the availability of funds is affected by various financial covenants and
collateral requirements. At June 30, 1996, $13.3 million was outstanding under
these foreign facilities, and the weighted average interest rate was 5.29%.
 
    Based on covenant and collateral limitations under the above revolving
credit facilities, the Company had an additional $49.5 million available for
borrowing at June 30, 1996.
 
    In February 1996, the Company modified its unsecured term loan facility for
$25 million with Sanwa Bank California ("Sanwa Term Facility"). The size of this
facility was reduced to $19.7 million and the interest rate for loans drawn
under this facility was reduced to LIBOR plus 0.75%. Principal repayments on
loans under the Sanwa Term Facility are required to be made in equal quarterly
installments from March 1998 through December 2001. This facility contains the
same financial covenants and ratios as contained in the three unsecured
revolving credit facilities mentioned above. At June 30, 1996, there was $19.7
million outstanding under this facility.
 
    In March 1996, the Company entered into a second unsecured term loan
facility for $25 million with Sanwa Bank California ("Sanwa Term Facility #2").
Under this facility, the Company may draw up to $25 million prior to December
31, 1996. Interest rates for loans drawn under this facility are at prime, or
LIBOR plus 0.75%, or the bank's cost of funds plus 0.75% (at the Company's
option). Principal repayments on loans under the Sanwa Term Facility #2 are
required to be made in equal quarterly installments from March 1999 through
December 2002. This facility contains the same financial covenants and ratios as
contained in the three unsecured revolving credit facilities mentioned above. At
June 30, 1996, no borrowings were outstanding under this facility.
 
    In June 1996, the Company entered into an unsecured term loan facility for
$20 million with Sumitomo Trust & Banking Co., Ltd., Los Angeles Agency
("Sumitomo Facility") and a separate unsecured term loan facility for $20
million with Banque Nationale de Paris, Los Angeles Branch ("BNP Facility").
From each of these facilities, the Company may draw up to $20 million prior to
June 30, 1997. Interest rates for loans drawn under the Sumitomo Facility are at
LIBOR plus 0.65%, and interest rates for loans drawn under the BNP Facility are
at LIBOR plus 0.55%. Principal repayments on loans under the Sumitomo Facility
are required to be made in equal semi-annual installments from December 1998
through June 2001. Principal repayments on loans under the BNP Facility are
required to be made in equal quarterly installments from September 1998 through
June 2001. These facilities contain the same financial covenants and ratios as
contained in the three unsecured revolving credit facilities mentioned above. At
June 30, 1996, no borrowings were outstanding under these facilities.

    In connection with an April 24, 1991 public offering of the Company's common
stock, 700,000 warrants previously issued by the Company were exercised and sold

exercise of the warrants was credited to capital contributed in excess of par
value.

    SHAREHOLDER RIGHTS PLAN (UNAUDITED)
 
    On August 2, 1996, the Company's Board of Directors adopted a Shareholder
Rights Plan (the "Plan") under which preferred stock purchase rights (the
"Rights") will be granted for each outstanding share of the Company's common
stock held at the close of business on August 14, 1996. The Plan is intended to
ensure fair and equitable treatment for all shareholders in the event of
unsolicited attempts to acquire the Company.
 
    The Rights will become exercisable ten days after a person or group (the
"Acquiror") has acquired beneficial ownership of 20% or more of the Company's
common stock other than pursuant to a qualified offer, or announces or commences
a tender offer or exchange offer that could result in the acquisition of
beneficial ownership of 20% or more. Once exercisable, each Right entitles the
holder to purchase one one-thousandth of a share of a new series of preferred
stock at an exercise price of $135, subject to adjustment to prevent dilution.
If the Acquiror acquires 20% or more of the Company's common stock, each Right
(except those held by the Acquiror) entitles the holder to purchase either the
Company's stock or stock in the merged entity at half of market value. The
Rights have no voting power, expire on August 14, 2006, and may be redeemed at a
price of $0.01 per Right up to and including the tenth business day after a
public announcement that 20% or more of the Company's shares have been acquired
by the Acquiror.
 
    For additional information, refer to the Company's reports to the Securities
and Exchange Commission on Forms 8-K and 8-A filed on August 20, 1996 and August
21, 1996, respectively.

    During fiscal 1996, the Company fully utilized its $4.9 million of U.S.
federal income tax credit carryovers. At June 30, 1996, the Company has
approximately $3.8 million of state tax credits which expire in 2002.
 
6.  PROFIT SHARING AND RETIREMENT PLANS
    The Company has established defined contribution plans for all eligible
employees. The Profit Sharing and Retirement Plan provided for contributions by
the Company in such amounts as the Board of Directors determined annually.
Effective November 1, 1995, the Company elected to terminate its Profit Sharing
and Retirement Plan in order to focus on improvements in its voluntary

Retirement Savings Plan (401K). Employees and former employees not fully vested
at time of the plan termination became 100% vested and were given various
distribution options as defined by ERISA. Under the established Retirement
Savings Plan (401K), the Company made an annual contribution for each
participating employee of up to $1,200 in fiscal year 1996 and up to $600 in
fiscal years 1995 and 1994. Combined plan contributions by the Company totaled
$1,021,000, $1,027,000, and $841,000 for fiscal years 1996, 1995, and 1994,
respectively.
 
7.  ENVIRONMENTAL MATTERS
    Federal, state, and local laws and regulations impose various restrictions
and controls on the discharge of certain materials, chemical, and gases used in
semiconductor processing. The Company does not believe that compliance with such
laws and regulations will have a material adverse effect on its financial
position.
 
    The Company and Rachelle Laboratories, Inc. ("Rachelle"), its former
pharmaceutical subsidiary which discontinued operations in 1986, have been named
among several hundred entities as potentially responsible parties ("PRPs") under
the provisions of the Comprehensive Environmental Response, Compensation and
Liability Act of 1980 ("CERCLA"), in connection with the United States
Environmental Protection Agency's ("EPA") investigation of the disposal of
allegedly hazardous substances at a major superfund site in Monterey Park,
California (the "OII Site"). Certain PRPs who settled certain claims with the
EPA under consent decrees filed suit in Federal Court in May 1992 against a
number of other PRPs, including the Company, for cost recovery and contribution
under CERCLA. The lawsuit against the Company, relating to the first and second
consent decrees, was settled in August 1993 for the sum of $40,000 to avoid
protracted and expensive litigation. In June 1995, the Company was named among
others as a party defendant in Federal Court apparently in connection with a
third consent decree with respect to the OII Site. The Company received a letter
(dated July 25, 1995) from the U.S. Department of Justice offering to settle
claims against Rachelle relating to the first three elements of clean-up work at
the OII Site for the sum of $4,953,148 (the final remedy assessment has not yet
been made). This settlement offer expired by its terms on September 1, 1995. The
Company also received a separate letter from the EPA dated July 25, 1995, with
respect to International Rectifier only, notifying the Company that it may
qualify for a settlement with de minimis generators under CERCLA Section 122(g).
The Company has received no further communications in this regard. At an August
17, 1995 meeting with EPA representatives and representatives of other PRPs, EPA
representatives stated that they will not have an estimate of the cost of final
clean-up until at least early 1996. The Company is unaware of any estimate of
the cost of final clean-up of the site.
 
    On August 7, 1995, the Company received a Supplemental Information Request
from the EPA, directed to Rachelle. In its response, dated October 20, 1995, the
Company explained that none of the wastes generated by Rachelle were hazardous.
The Company has received no further communications in connection with the
Supplemental Information Request.
 
    Claims have been made with the Company's insurers with respect to the OII
site matter; however, there can be no assurance that the insurance coverage
attaches to these claims. The Company does not believe that either it or
Rachelle is responsible for the disposal at the OII site of any material
constituting hazardous substances under CERCLA. Although the ultimate resolution
of this matter is unknown, the Company believes that it will not have a material
adverse impact on its financial position.
 
    In May 1993, the Company purchased property from its Employee Profit Sharing
and Retirement Plan. It was determined that the property required clean-up of
seepage from a storage tank, at an
 
                                       33

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
7.  ENVIRONMENTAL MATTERS (CONTINUED)
estimated additional cost of $525,000. The Company commenced the clean-up in
fiscal year 1994, and through June 30, 1996 approximately $518,000 in clean-up
costs have been incurred which will be capitalized as additional costs of the
property.
 
    On July 18, 1994, the Company received a letter from the State of Washington
Department of Ecology (the "Department") notifying the Company of a proposed
finding that the Company is a potentially liable person ("PLP") for alleged PCE
contamination (also known as perchloroethylene, tetrachloroethylene, and other
names) of real property and groundwater in Yakima County, Washington. The letter
alleges that the Company arranged for disposal or treatment of the PCE or
arranged with a transporter for the disposal or treatment of the PCE in Yakima
County. The Company replied by a letter dated August 11, 1994, stating that it
has not contributed to PCE or other solvent contamination at the Yakima County
site (resulting from sending carbon canisters for regeneration to a facility in
the county) and that it should not be designated a PLP. On October 11, 1994, the
Company received a letter from the Department notifying the Company of its
finding that the Company is a PLP in the above matter. On June 20, 1996, the
Company received a letter from the Washington Department of Ecology, stating
that a settlement offer would be extended to all potentially liable persons in
late summer or early fall of 1996. While the letter did not commit to the amount
of any settlement, it predicted a settlement of approximately $4.95 for each
pound of carbon sent to Cameron-Yakima.
 
    The Company received a letter dated September 9, 1994, from the State of
California Department of Toxic Substances Control stating that the Company may
be a PRP for the deposit of hazardous substances at a facility in Whittier,
California. The Company, in June 1995, agreed to join a group of other PRPs to
remove contamination from the site. The group currently estimates the total cost
of the clean-up to be between $3.1 million and $4 million, of which between
$12,000 and $15,000 is presently expected to be allocated to the Company.
However, the ultimate cost borne by the Company will depend on the extent of the
clean-up undertaken by the group and the actual clean-up costs and the final
allocation scheme agreed upon by the group.

9.  INTELLECTUAL PROPERTY RIGHTS
    Certain of the Company's fundamental power MOSFET patents have been
subjected, and continue to be subjected, to reexamination in the United States
Patent and Trademark Office ("PTO"). The patents subject to reexamination are
fundamental to the Company's MOS transistors and their loss would allow
competitors to use currently patented features of the Company's MOS transistor

October 13, 1993 on patent 4,705,759; September 12, 1994 on patent 4,959,699;
September 23, 1994 and June 28, 1995 on patent 5,008,725; January 17, 1995 on
patent 5,130,767; June 5, 1995 on patent 5,191,396; and June 14, 1995 on patent
4,593,302. On February 14, 1995 and on December 26, 1995, respectively, the PTO
issued reexamination certificates, confirming the patentability of the Company's
U.S. patents 4,705,759 and 5,191,396.
 
10. LITIGATION
    The Company and SGS-Thomson Microelectronics, Inc. ("SGS") are engaged in
various legal proceedings relating to their respective power MOSFET patents. SGS
filed suit against the Company in June 1991 in Federal District Court in Texas,
charging infringement of U.S. patent 4,553,314. On motion by the Company, the
suit was transferred to the Federal District Court in Los Angeles, California,
and thereafter SGS amended its complaint to charge infringement of U.S. patents
4,495,513 and 4,712,127. SGS alleges, in substance, that the Company's power
MOSFET, power IC and IGBT products infringe the '314 patent, that the Company's
IGBT products infringe the '513 patent, and that certain packages for the
Company's products (including certain power MOSFET packages) infringe the '127
patent. The complaint, as amended, seeks unspecified actual damages (but no less
than an unspecified reasonable royalty) and an injunction restraining further
sales of such products. On February 1, 1993, the District Court dismissed SGS's
claims for infringement of the '127 and '513 patents for lack of standing and on
March 15, 1993, ruled that the SGS '314 patent is unenforceable due to
inequitable conduct. SGS appealed these rulings, as well as the order
transferring the case to California, to the Court of Appeals for the Federal
Circuit. The Company cross-appealed a separate ruling by the District Court
denying the Company's motion for summary judgment that the '314 patent is
invalid. In July 1994, the Federal Circuit vacated the District Court's grants
of summary judgment as to the '513, '127, and '314 patents and affirmed the
District Court's denial of the Company's motion for summary judgment of
invalidity of the '314 patent. The Federal Circuit ordered, however, that the
case should proceed in California. On July 5, 1995, the Court, based on the
stipulation of the parties, effectively stayed SGS's claims on its '314 and '127
patents pending the outcome of reexamination of the patentability of the subject
matter of those patents by the PTO. These reexamination proceedings are still
pending.
 
    In November and December 1995, the parties presented testimony and evidence
to the District Court concerning the interpretation of the claims of the '513
patent; and the Court has not yet ruled on the matter.
 
    The Company has also filed a separate action in the same District Court
against SGS and its Italian affiliate, SGS-Thomson Microelectronics, S.r.l.,
seeking an injunction against infringement of the Company's U.S. patents
5,008,725 and 5,130,767. This action has been essentially stayed pending
completion of reexamination of these patents by the PTO (see Note 9).
 
    The Company filed another separate action in the same District Court on
August 13, 1996, against the same SGS entities charging infringement of its U.S.
patent 5,545,955.
 
    In the Fall of 1995, SGS and SGS-Thomson Microelectronics, S.A.
("SGS-France") commenced an infringement action in Great Britain against the
Company and International Rectifier (Great Britain) Limited ("IRGB") based on
the European counterpart patent to the '513 patent (European Patent (UK) No.
0,068,546). The Company and IRGB have filed a response denying the material
allegations plead by SGS and SGS-France and seek revocation of the foreign
counterpart patents at issue. The British action is set for trial in July 1997.

10. LITIGATION (CONTINUED)
    The Company, its directors, and certain officers have been named as
defendants in three class action lawsuits filed in Federal Court in California.
These suits seek unspecified but substantial compensatory and punitive damages
for alleged intentional and negligent misrepresentations and violations of the
federal securities laws. The complaints generally allege that the Company and
the other defendants made materially false statements or omitted to state
material facts in connection with the public offering of the Company's common
stock completed in April 1991 and the redemption and conversion in June 1991 of
the Company's 9% Convertible Subordinated Debentures Due 2010. They also allege
that the Company's projections for growth in fiscal 1992 were materially
misleading. Although the Company believes that the claims alleged in the suits
are without merit, the ultimate outcome cannot be presently determined. A
substantial judgment or settlement, if any, could have a material adverse effect
on the Company's financial condition and results of operations. Two of these
suits also name Kidder, Peabody & Co. Incorporated and Montgomery Securities as
defendants. Defendants Kidder, Peabody & Co. and Montgomery Securities have
demanded that the Company indemnify them for any liability or expenses,
including attorneys fees, that they may incur in connection with this
litigation. Those defendant underwriters base that demand on their underwriting
agreements with the Company. The Company has agreed to advance the underwriter
defendants' attorneys fees pursuant to that indemnity, subject to a reservation
of the Company's right to seek reimbursement of those advances.
 
    No provision for any liability that may result upon adjudication of these
matters has been made in the consolidated financial statements.
 
    The Company is currently involved in litigation arising in the normal course
of business. Management does not believe that the ultimate resolution of this
litigation will have a material adverse impact on the financial position of the
Company (also see Notes 7 and 9).
 
11. EXECUTIVE AGREEMENT
    The Company entered into an executive agreement with Eric Lidow dated May
15, 1991 providing for his continued employment with the Company for a six year
period as Chief Executive Officer and President or in such other position as the
Board of Directors may determine. Mr. Lidow's salary at fiscal year end under
this agreement was $632,500. Upon Mr. Lidow's retirement from the Company (or a
change in control) he will receive annual payments (Founder's Pension) of 90% of
his then current salary. The agreement was amended on April 12, 1995 to provide
that upon retirement Mr. Lidow's pension would be based, in addition to his
salary, on the average of the prior three years' cash bonuses, if any. The
pension would further be adjusted annually to account for any increase in the
Consumer Price Index. Upon Mr. Lidow's death, payments will be continued to his
wife, if she survives him, in an amount equal to two-thirds of his retirement
benefits for the remainder of her life. Under the terms of the Founder's
Pension, $2,348,000, $1,068,000, and $572,000 have been expensed in fiscal years
1996, 1995, and 1994, respectively.
 
    On October 24, 1995 (amended on February 22, 1996), the Company established
an irrevocable grantor trust (the "Trust") for payment of retirement benefits to
Eric Lidow and his wife. The principal of the Trust, and any earnings thereon,
shall be held separate and apart from other funds of the Company and shall be
used exclusively for the uses and purposes of providing the retirement benefits
described in the executive agreement (and for payments to general creditors if
the Company is unable to pay its debts as they become due or is subject to a
pending proceeding as a debtor under the United States Bankruptcy Code). Under
the Trust agreement, the Company funds the pro-rata liability accrual 30 days
following the end of each calendar quarter. At June 30, 1996, the balance in the
Trust was $5,219,000 and was included in "Other assets."

                                  THE TERM LOAN

     2.01 TERM LOAN. The Bank agrees to lend to the Borrower in up to 5 drawings
in the minimum amount of $1,000,000, upon the Borrower's request made prior to
December 31, 1995, (the "Drawdown Period") up to the maximum amount of
$25,000,000 (the "Term Loan").

          A. PURPOSE. Proceeds from the Term Loan shall be used to finance
acquisition of assets.

          B. TERM LOAN ACCOUNT. The Bank shall maintain on its books a record of
account in which the Bank shall make entries setting forth all payments made,
the application of such payments to interest and principal, accrued and unpaid
interest (if any) and the outstanding principal balance under the Term Loan (the
"Term Loan Account). The Bank shall provide the Borrower with a monthly
statement of the Borrower's Term Loan Account, which statement shall be
considered to be correct and conclusively binding on the Borrower unless the
Borrower notifies the Bank to the contrary within 30 days after the Borrower's
receipt of any such statement which it deems to be incorrect.

          C. INTEREST. Interest shall accrue on the outstanding principal
balance or any portion of the outstanding principal balance of the Term Loan at
one of the following rates as elected by Borrower:

               (a) VARIABLE RATE BALANCES. The outstanding principal balance of
the Term Loan ("Term Balance") shall bear interest at a rate equal to Bank's
Reference Rate per annum, as it may change from time to time ("Variable Rate").
The rate of interest shall be adjusted concurrently with any change in Bank's
Reference Rate. The Term Balance bearing interest at the Variable Rate is
hereinafter referred to as "Variable Rate Balances".

               (b) FIXED RATE BALANCES. A fixed rate for such period of time
that the Bank may quote and offer in its sole discretion from time to time (the
"Fixed Rate"), provided that any such period of time shall be for at least 7
days and provided further that any such period of time does not extend beyond
the maturity date of the Term Loan (the "Fixed Rate Interest Period") The Bank
shall provide the Borrower with a statement of the Borrower's Fixed Rate, which
statement shall be considered to be correct and conclusively binding on the
Borrower unless the Borrower notifies the Bank to the contrary within 30 days
after the Borrower's receipt of any such statement which it deems to be
incorrect. The Term Balance bearing interest at the Fixed Rate is hereinafter
referred to as "Fixed Rate Balances".

               (c) EURODOLLAR BALANCES. A fixed rate quoted by the Bank for a
minimum of 30 days or for such other period of time that the Bank may quote and
offer [the "Eurodollar Interest Period"] for Term Balances in the minimum amount
of $100,000.00. Such interest rate shall be a percentage equivalent to 1.00% per
annum in excess of the Bank's Eurodollar Rate which is that rate determined by
the Bank's Treasury Desk as being the approximate rate at which the Bank could
purchase offshore U.S. dollar deposits in an amount approximately equal to the
amount of the relevant Term Balance and for a period of time approximately equal
to the relevant Eurodollar Interest Period (adjusted for any and all
assessments, surcharges and reserve requirements pertaining to the purchase by
the Bank of such U.S. dollar deposits) [the "Eurodollar Rate"]. Term Balances
based upon the Eurodollar Rate is hereinafter referred to as the "Eurodollar
Balances".

          Borrower hereby promises and agrees to pay interest on any Variable
Rate Balances monthly in arrears on the first calendar day of each month.

                                       -2-
<PAGE>

          Interest on any Eurodollar Balance or any Fixed Rate Balance with a
Eurodollar Interest Period or a Fixed Rate Interest Period (hereinafter referred
to as an "Interest Period") of 93 or less days shall be paid on the last day of
the relevant Eurodollar Interest Period or Fixed Rate Interest Period pertaining
to such Eurodollar Balance or Fixed Rate Balance. Interest on any Eurodollar
Balance or Fixed Rate Balance with an Eurodollar Interest Period or Fixed Rate
Interest Period in excess of 93 days shall be paid quarterly (i.e., on the last
day of each 3 month period occurring in such Interest Period) and on the last
day of the relevant Eurodollar Interest Period or Fixed Rate Interest Period
pertaining to such Eurodollar Balance or Fixed Rate Balance.

          Interest shall be calculated on a year of 360 days for actual days
elapsed.

               (d) NOTICE OF ELECTION TO ADJUST INTEREST RATE. Upon telephonic
notice which shall be received by the Bank at or before 2:00 p.m. (California
time) on a business day, the Borrower may elect:

                    1) That interest on a Variable Rate Balance shall be
adjusted to accrue at the Fixed Rate or the Eurodollar Rate; provided, however,
that such notice shall be received by the Bank no later than two business days
prior to the day (which shall be a business day) on which Borrower requests that
interest be adjusted to accrue at the Fixed Rate or Eurodollar Rate.

                    2) That interest on a Fixed Rate Balance or Eurodollar
Balance shall continue to accrue at a newly quoted Fixed Rate or Eurodollar Rate
as the case may be or shall be adjusted to commence to accrue at the Variable
Rate; provided, however that such notice shall be received by the Bank no later
than two business days prior to the last day of the Interest Period or
Eurodollar Interest Period pertaining to such Fixed Rate Balance or Eurodollar
Balance. If the Bank shall not have received notice as prescribed herein of
Borrower's election that interest on any Fixed Rate Balance or Eurodollar
Balance shall continue to accrue at the Fixed Rate or Eurodollar Rate as the
case may be, Borrower shall be deemed to have elected that interest thereon
shall be adjusted to accrue at the Variable Rate upon the expiration of the
Interest Period pertaining to such Term Balance.

               (e) PREPAYMENT. Notwithstanding anything to the contrary in the
Agreement, no prepayment shall be made on any Fixed Rate Balance or Eurodollar
Balance except on a day which is the last day of the relevant Interest Period or
Eurodollar Interest Period pertaining thereto. If the whole or any part of any
Fixed Rate Balance or Eurodollar Balance is prepaid by reason of acceleration or
otherwise, the Borrower shall upon the Bank's request, promptly pay to and
indemnify the Bank for all costs and any loss (including interest) actually
incurred by the Bank and any loss (excluding loss of profit resulting from the
re-employment of funds) sustained by the Bank as a consequence of such
prepayment. Any prepayment shall first be applied to pay accrued interest, then
be applied to reduce the principal balance payable on the date set forth in
numbered paragraph 3 hereinbelow, and the remaining portion (if any) of such
prepayment shall then be applied to pay the principal installment(s) of latest
maturity under this Term Loan.

               (f) INDEMNIFICATION FOR FIXED RATE AND EURODOLLAR RATE COSTS.
During any period of time in which interest on any Term Balance is accruing on
the basis of the Fixed Rate or Eurodollar Rate, the Borrower shall, upon the
Bank's written request, which request shall explain in reasonable detail the
reason for such costs or payments, promptly pay to and reimburse the Bank for
all costs incurred and payments made by the Bank by reason of any future
assessment, reserve, deposit or similar requirements or any surcharge, tax or
fee imposed upon the Bank or as a result of the Bank's compliance with any
directive or requirement of any regulatory authority pertaining or relating to
funds used by the Bank in quoting and determining the Fixed Rate or Eurodollar
Rate.

               (g) CONVERSION FROM FIXED RATE OR EURODOLLAR RATE TO VARIABLE
RATE. In the event that the Bank shall at any time determine that the accrual of
interest on the basis of the Fixed Rate or Eurodollar Rate (i) is infeasible
because the Bank is unable to determine the Fixed Rate or Eurodollar Rate due to
the unavailability of U.S. dollar deposits, contracts or certificates of deposit
in an amount approximately equal to the amount of the relevant Balance and for a
period of time approximately equal to the relevant Interest Period; or (ii) is
or has become unlawful or infeasible by reason of the Bank's compliance with any
new law, rule, regulation, guideline or order, or any new interpretation of any
present law, rule, regulation, guideline or order, then the Bank shall give
telephonic notice thereof (confirmed in writing) to the Borrower, in which event
any Fixed Rate Balance or Eurodollar Balance shall be deemed to be a Variable
Rate Balance and interest shall thereupon immediately accrue at the Variable
Rate.

               D. PRINCIPAL. The Borrower hereby promises and agrees to pay the
outstanding principal of the Term Loan as of December 31, 1995, in 15 equal
installments of 1/16th of the outstanding principal balance of the Term Loan as
of December 31, 1995, commencing on March 31, 1998, and continuing on the last
day of each calendar quarter thereafter up to and including September 30,
2001. On December 31, 2001, the Borrower hereby promises and agrees to pay to
the Bank the entire unpaid principal balance, together with accrued and unpaid
interest.

     Each payment received by the Bank shall be applied to pay interest then due
and unpaid and the remainder thereof (if any) shall be applied to pay principal.

               E. ACCOUNT DEBIT Upon prior notice to the Borrower from the Bank,
the Borrower hereby authorizes the Bank, if and to the extent payment owed to
the Bank under the Term Loan is not made when due, after giving effect to any
grace period, to charge, from time to time, against any or all of the Borrower's
deposit accounts with the Bank any amount so due.

               F. COMMITMENT FEE. Borrower agrees to pay to Bank a commitment
fee during the Drawdown Period of.25% per annum on the undrawn portion of the
Term Loan, payable quarterly in arrears and computed on a year of 360 days for
actual days elapsed.

     2.02 LIMITATIONS.

               (a) Notwithstanding anything to the contrary herein, the Borrower
shall not be required to make any payment to the Bank with respect to any
indemnity required pursuant to Sections 2.01 C. (f) ("Affected Section") unless
Bank shall have given notice to Borrower promptly upon the Rosemead Commercial
Banking Center of Bank, or its equivalent successor, becoming aware of any
circumstance requiring the Borrower to make any payment under an Affected
Section;

               (b) The Borrower shall not be responsible for payment of any
amounts payable under any Affected Section to the extent determined to be as a
result of the Bank's gross negligence or willful misconduct.

               (c) The Bank shall use its reasonable efforts (consistent with
its internal policy and legal and regulatory restrictions) to take any action if
the taking of such action would avoid the need for, or reduce the amount of, any
additional amounts payable under any Affected Section or not require the
prepayment of a Fixed Rate Advance and would not, in the reasonable judgment of
the Bank, be otherwise disadvantageous to the Bank.

                                    SECTION 3

                              CONDITIONS OF LENDING

     3.01 CONDITIONS PRECEDENT TO THE INITIAL ADVANCE: The obligation of the
Bank to make the first extension of credit to or on account of the Borrower
hereunder is subject to the conditions precedent that the Bank shall have
received before the date of such first extension of credit all of the following,
in form and substance satisfactory to the Bank:

          (a) Evidence that the execution, delivery and performance by the
Borrower of this Agreement and any document, instrument or agreement required
hereunder have been duly authorized.

          (b) A flat fee of $62,500.00 which shall include all of Bank's out-of-

with respect to the following:

    This Amendment shall be deemed to be a part of and subject to that certain
Term Loan Agreement dated as of February 28, 1995, as it may be amended from
time to time, and any and all addenda and riders thereto (collectively the
"Agreement"). Unless otherwise defined herein, all terms used in this Amendment
shall have the same meanings as in the Agreement. To the extent that any of the
terms or provisions of this Amendment conflict with those contained in the
Agreement, the terms and provisions contained herein shall control.

    WHEREAS, the Borrower and the Bank mutually desire to modify the Agreement.

the Bank agree as follows:

         1. CHANGE IN TERM LOAN.  The first paragraph of Section 2.01 of the
Agreement is deleted in its entirety and the following is substituted in lieu
thereof:

         "2.01 TERM LOAN. The Bank agrees to lend to the Borrower in up to 5
    drawings in the minimum amount of $1,000,000, upon the Borrower's request
    made prior to March 31, 1996, (the "Drawdown Period") up to the maximum

    minimum of 30 days or for such other period of time that the Bank may quote
    and offer [the "Eurodollar Interest Period"] for Term Balances in the
    minimum amount of $100,000.00. Such interest rate shall be a percentage
    equivalent to .75% per annum in excess of the Bank's Eurodollar Rate which
    is that rate determined by the Bank's Treasury Desk as being the
    approximate rate at which the Bank could purchase offshore U.S. dollar
    deposits in an amount approximately equal to the amount of the relevant
    Term Balance and for a period of time approximately equal to the relevant
    Eurodollar Interest Period (adjusted for any and all assessments,
    surcharges and reserve requirements pertaining to the purchase by the Bank
    of such U.S. dollar deposits) [the "Eurodollar Rate"]. Term Balances based
    upon the Eurodollar Rate is hereinafter referred to as the "Eurodollar

    Debt then due for the 4th immediately preceding fiscal quarter, plus net
    interest expense for the immediately preceding 4 fiscal quarters of not

                      GRANTOR TRUST FOR RETIREMENT BENEFITS

                                 FOR ERIC LIDOW

<PAGE>

                      INTERNATIONAL RECTIFIER CORPORATION
                     GRANTOR TRUST FOR RETIREMENT BENEFITS
                                 FOR ERIC LIDOW

     This Agreement, made effective as of the 24th day of October, 1995,  by
and  between  International  Rectifier  Corporation  (the "Company") and Union
Bank (the "Trustee"), evidences the terms of a trust to hold assets in respect
of the retirement benefits payable to Eric Lidow, and his spouse if she survives
him, pursuant to Paragraph 3(a)(iii)  of the employment agreement, dated as of
May 15, 1991, between the Company and Eric Lidow as amended by the letter
agreement dated April 12, 1995 (the "Employment Agreement").

     WHEREAS, under the terms of the Employment Agreement, a copy of which is
attached hereto as Exhibit A, the Company is obligated to provide retirement
benefits to Eric Lidow and, if she survives him, his spouse;

     WHEREAS, the Company wishes to establish a trust (hereinafter referred to
as the "Trust") and to contribute to the Trust assets that shall  be  held
therein,  subject  to  the  claims  of  the  Company's creditors in the event of
the Company's Insolvency, as herein defined, until paid to Eric Lidow or his
spouse in such manner and at such times as specified in the Employment
Agreement;

     WHEREAS, it is the intention of the parties that this Trust shall
constitute an unfunded arrangement and shall not affect the status of the
Company's obligation under the Employment Agreement as an unfunded promise to
pay deferred compensation to Eric Lidow for purposes of Title I of the Employee
Retirement Income Security Act of 1974; and

     WHEREAS, it is the intention of the Company to make contributions to the
Trust to provide itself with a source of funds to assist it in the  meeting  of
its  obligation  under  the  Employment  Agreement  to provide retirement
benefits to Eric Lidow.

     NOW, THEREFORE, the parties do hereby establish the Trust, to be known as
the "INTERNATIONAL RECTIFIER CORPORATION TRUST FOR RETIREMENT BENEFITS FOR ERIC
LIDOW," and agree that the Trust shall be comprised, held and disposed of as
follows:

SECTION 1.  ESTABLISHMENT OF TRUST; GENERAL ADMINISTRATION.

      (a)  The Company hereby deposits with the Trustee in trust $100,
which shall become the principal of the Trust to be held, administered
and disposed of by the Trustee as provided in this Trust Agreement.

     (b)  The Trust hereby established shall be irrevocable.

     (c)  The Trust is intended to be a grantor trust, of which the
Company is the grantor, within the meaning of subpart E, part I,

                                        1

<PAGE>

subchapter J, chapter 1, subtitle A of the Internal Revenue Code of 1986, as
amended, and shall be construed accordingly.

      (d)  The principal of the Trust, and any earnings thereon, shall
be held separate and apart from other funds of the Company and shall
be  used  exclusively  for  the  uses  and  purposes  of  providing  the
retirement benefits described in the Employment Agreement and general
creditors as herein set forth.  Eric Lidow and his spouse shall have
no preferred claim on, or any beneficial ownership interest in, any
assets  of  the  Trust.   Any  rights  created  under  the  Employment
Agreement and this Trust Agreement shall be mere unsecured contractual
rights of Eric Lidow and his spouse against the Company.  Any assets
held by the Trust will be subject to the claims of the Company's
general  creditors  under  federal  and  state  law  in  the  event  of
Insolvency, as defined in Section 3(a) herein.

      (e)  Within  30  days  following  the  execution  of  this  Trust
Agreement,  the  Company  shall  irrevocably  deposit  cash  or  other
property to the Trust in an amount equal to $3,000,000.  Thereafter,
within 30 days following the end of each calendar quarter, the Company
shall irrevocably deposit additional cash or other property to the
Trust in an amount equal to the excess of (A) over (B) where (A)
equals the lump sum Actuarial Equivalent (as defined below) of the
retirement benefits payable to Eric Lidow and his spouse as of the end
of such calendar quarter and (B) equals the fair market value of the
Trust's assets as of the end of such calendar quarter.  For purposes
of this Trust Agreement, "Actuarial Equivalent" shall mean a benefit
of equal value computed using an interest rate of 8%, the 1983 GAM
Male (0, -6) Mortality Table, and an assumption of a 4% increase in
the Consumer Price Index referred to in the Employment Agreement for
future years.

      (f)  The Company shall certify in writing to the Trustee the
names and specimen signatures of all those who are authorized to act
as  or  on  behalf  of  the  Company,  and  those  names  and  specimen
signatures shall be updated as necessary by a duly authorized official
of the Company.  The Company shall promptly notify the Trustee if any
person so designated is no longer authorized to act on behalf of the
Company.  Until the Trustee receives notice that a person is no longer
authorized to act on behalf of the Company, the Trustee may continue
to rely on the Company's designation of such person.

      (g)  The Trustee may seek written instructions from the Company
on any matter and await written instructions without incurring any
liability.  If at any time the Company should fail to give directions
to  the  Trustee,  the  Trustee  may  act  in  the  manner  that  in  its
discretion seems advisable under the circumstances for carrying out
the purposes of the Trust.  Such actions shall be conclusive on the
Company, Eric Lidow and his spouse on any matter if written notice of
the proposed action is given five (5) days prior to the action being
taken, and the Trustee receives no response.  In case of emergency,
the Trustee may act in the absence of directions from any other person
having the power and duty to direct the Trustee with respect to the
matter involved and shall incur no liability in so acting.

                                        2

<PAGE>

      (h)  The Company shall maintain and furnish the Trustee with all
reports, documents and information as shall be required by the Trustee
to perform its duties and discharge its responsibilities under this
Trust Agreement, including without limitation a certified copy of any
amendments to the Employment Agreement and, following a Change in
Control of the Company, written reports setting forth all information
required  to  calculate  Eric  Lidow's  benefit  under  the  Employment
Agreement.

      (i)  The Trustee shall have no liability for the adequacy of
contributions for the purposes of the Employment Agreement or for
enforcement of the payment thereof.

      (j)  The  Trustee  shall  have  no  liability  for  the  acts  or
omissions of the Company.

     (k)  The Company, by adoption of this Trust Agreement, agrees to
indemnify  the  Trustee  and  any  agent  such  parties  appoint  for
reasonable expenses and to exonerate and  indemnify them to their
reasonable satisfaction, from time to time, for or against any and all
loss, expense and liability incurred or to be incurred by them for
acts or omissions of the Company or any of its employees.

     (1)  The Company agrees to indemnify the Trustee against any liability
imposed as a result of a claim asserted by any person or persons with respect to
whom the Trustee has acted in good faith in reliance on a written direction of
the Company.

SECTION 2. PAYMENTS TO ERIC LIDOW AND/OR HIS SPOUSE.

      (a)  Upon  the  Corporation's  termination  of  Eric  Lidow's
employment for any reason other than Cause, or upon Eric Lidow's
resignation following a Change in Control of the Company (as "Cause"
and "Change in Control") are defined in Employment Agreement, or upon
Eric Lidow's death, the Company or such party as it shall designate in
writing to the Trustee shall deliver to the Trustee a written schedule
(a "Payment Schedule") that indicates the amounts payable to Eric
Lidow or his spouse, or that provides a formula or other instructions
acceptable to Trustee for determining the amounts so payable, the form
in  which  such  amount  is  to  be  paid  (as  provided  for  under  the
Employment Agreement), and the time of commencement for payment of
such amounts.  Except as otherwise provided herein, the Trustee shall
make payments to Eric Lidow or his spouse in accordance with such
Payment Schedule.  The Trustee shall make provision for the reporting
and withholding of any federal, state or local taxes that may be
required  to  be withheld with  respect  to the payment  of  benefits
pursuant to the terms of the Employment Agreement and shall pay  the
amounts withheld to the appropriate taxing authorities or determine
that  such  amounts  have  been  reported,  withheld  and  paid  by  the
Company.    The  Trustee  shall  provide  the  Company  with  written
confirmation of the fact and time of any payment hereunder within 10
days of payment.

                                        3

<PAGE>

      (b)  The entitlement of Eric Lidow or his spouse to retirement
benefits under the Employment Agreement shall be determined by the
Company or such party as it shall designate under the Employment
Agreement.  Notwithstanding the foregoing or anything else contained
in this Trust Agreement to the contrary, upon a Change in Control of
the  Company,  the  responsibility  of  the  Company  and  any  of  its
delegates for determining benefit entitlement or directing any payment
or disbursement shall cease and the Trustee shall have full authority
and responsibility for such matters.

      (c)  The Trustee shall provide the Company with written confirma-
tion of the fact and time of any payment hereunder within 10 business
days after making any payment to Eric Lidow or his spouse.

      (d)  The Company may make payment of benefits directly to Eric
Lidow  or  his  spouse  as  they  become  due  under  the  terms  of  the
Employment Agreement.  The Company shall notify the Trustee of its
decision to  make payment  of  benefits  directly  prior  to the time
amounts are payable to Eric Lidow or his spouse.  In addition, if the
principal of the Trust, and any earnings thereon, are not sufficient
to make payments of benefits in accordance with the terms of the
Employment Agreement, the Company shall make the balance of each such
payment as it falls due.  The Trustee shall notify the Company when
principal and earnings are not sufficient.

      (e)  Should any controversy arise as to the person or persons to
whom any distribution or payment is to be made by the Trustee, the
Trustee may retain the amount in controversy pending resolution of the
controversy or the Trustee may file an action seeking declaratory
relief and/or may interplead the Trust assets or fund in issue, and
name as necessary parties the Company, Eric Lidow, his spouse and/or
any or all persons making conflicting demands.  The Trustee shall not
be liable for the payment of any interest or income, except for that
earned as a Trust investment, on any amount withheld or interpleaded
under this Section 2(e).  The expenses of the Trustee for taking any
action under this Section 2(e) shall be paid to the Trustee by the
Company.

SECTION 3. TRUSTEE RESPONSIBILITY REGARDING PAYMENTS TO TRUST
           BENEFICIARY WHEN COMPANY IS INSOLVENT.

      (a)  The Trustee shall cease payment of benefits to Eric Lidow or
his  spouse  if  the  Company  is  Insolvent.   The  Company  shall  be
considered "Insolvent" for purposes of this Trust Agreement if (i) it
is unable to pay its debts as they become due, or (ii) it is subject
to a pending proceeding as a debtor under the United States Bankruptcy
Code.

      (b)  At  all  times  during  the  continuance  of  this  Trust,  as
provided in Section l(d) hereof, the principal and income of the Trust
shall be subject to claims of general creditors of the Company and its
affiliates under federal and state law, as set forth below.

                                        4

<PAGE>

                (i)  The Company's Board of Directors and its Chief
     Executive Officer shall have the duty to inform the Trustee in
     writing of the Company's Insolvency.  If a person claiming to be
     a creditor of the Company alleges in writing to the Trustee that
     the Company has become Insolvent, the Trustee shall determine
     whether the Company is Insolvent and, pending such determination,
     the Trustee shall discontinue payment of benefits to Eric Lidow
     or his spouse.

                (ii) Unless the Trustee has actual knowledge of the
     Company's Insolvency, or has received notice from the Company or
     a person claiming to be a creditor alleging that the Company is
     Insolvent, the Trustee shall have no duty to inquire whether the
     Company is Insolvent.  The Trustee may in all events rely on such
     evidence concerning the Company's solvency as may be furnished to
     the Trustee and that provides the Trustee with a reasonable basis
     for making a determination concerning the Company's solvency.

               (iii) If at any time the Trustee has determined that the
     Company is Insolvent, the Trustee shall discontinue payments to
     Eric Lidow or his spouse and shall hold the assets of the Trust
     for the benefit of the Company's general creditors.  Nothing in
     this Trust Agreement shall in any way diminish any rights of Eric
     Lidow or his spouse to pursue their rights as general creditors
     of the Company with respect to benefits due under the Employment
     Agreement or otherwise.

                (iv) The Trustee shall resume the payment of benefits
     to Eric Lidow or his spouse in accordance with Section 2 of this
     Trust Agreement only after the Trustee has determined that the
     Company is not Insolvent (or is no longer Insolvent).

      (c)  Provided that there are sufficient assets, if the Trustee
discontinues  the  payment  of  benefits  from  the  Trust  pursuant  to
Section 3(b) hereof and subsequently resumes such payments, the first
payment following such discontinuance shall include the aggregate
amount of all payments due to Eric Lidow or his spouse under the terms
of the Employment Agreement for the period of such discontinuance,
less the aggregate amount of any payments made to Eric Lidow or his
spouse by the Company in lieu of the payments provided for hereunder
during any such period of discontinuance.

SECTION 4.  PAYMENTS TO COMPANY.

     Except as provided in Section 3 or Section 11 hereof, the Company shall
have no right or power to direct the Trustee to return to the Company or to
divert to others any of the Trust assets before all payments of benefits have
been made to Eric  Lidow or his spouse pursuant to the terms of the Plans.

                                        5

SECTION 5. INVESTMENT AUTHORITY.

      (a)  Prior to a Change in Control, the Trustee shall invest and
manage the assets of the Trust in accordance with written directions
from the Administrative Committee, a committee to be appointed by the
Company, the members of which may be changed from time to time by the
Company (the "Committee").  Upon a Change in Control, the authority of
the Company and the Committee hereunder shall cease and the Trustee
shall  have  the  exclusive  authority  and  responsibility  for  the
investment of Trust assets.

      (b)  The Company shall have the right, at any time, and from time
to time in its sole discretion, to substitute assets of equal fair
market value for any asset held by the Trust.

      (c)  Subject to the foregoing provisions of this Section 5, the
Trustee shall have, without exclusion, all powers conferred on the
Trustee by applicable law, unless expressly provided otherwise herein,
and all rights associated with assets of the Trust shall be exercised
by the Trustee or the person designated by the Trustee, and shall in
no event be exercisable by or rest with Eric Lidow or his spouse.  The
Trustee shall have full power and authority to invest and reinvest the
Trust funds in any investment permitted by law, under the standards
set forth in Section 8(a) including, without limiting the generality
of the foregoing, the power:

           (i)  To hold, invest and reinvest the principal or income of
     the Trust in bonds, common or preferred stock, other securities,
     or other personal, real or mixed tangible or intangible property
     (including  investment  in  deposits with  Trustee  which  bear a
     reasonable interest rate, including without limitation invest-
     ments in trust savings accounts, certificates of deposit, time
     certificates or similar investments or deposits maintained by the
     Trustee);

           (ii) To pay and provide for the payment of all reasonable
     and necessary expenses of administering the affairs of the Trust,
     subject to reimbursement of such expenses within 30 days by the
     Company in accordance with Section 9 hereof;

           (iii) To pay and provide for the payment of all benefits to
     Eric Lidow or his spouse in accordance with the Payment Sched-
     ules;

           (iv) To  retain  noninterest  bearing  deposits  or  a  cash
     balance with Trustee of so much of the funds as may be determined
     to be temporarily held awaiting investment or payment of benefits
     or expenses notwithstanding Trustee's receipt of "float" from
     such uninvested funds;

           (v)  To compromise, arbitrate or otherwise adjust claims in

account.  Upon the expiration of each such period, the Trustee shall be forever
released and discharged from all liability and accountability to the Company
with respect to the propriety of its acts and transactions shown in such account
except with respect to any such acts or transactions as to which the Company
files written objections within such 60-day period with the Trustee.

SECTION 8. RESPONSIBILITY OF TRUSTEE.

      (a)  The Trustee shall act with the care, skill, prudence and
diligence under  the  circumstances then prevailing  that  a prudent
person acting in like capacity and familiar with such matters would
use in the conduct of an enterprise of a like character and with like
aims; provided, however, that the Trustee shall incur no liability to
any person for any action taken pursuant to a direction, request or
approval  given  by  the  Company  which  is  contemplated  by,  and  in
conformity with, the terms of the Employment Agreement or this Trust
and is given in writing by the Company.  In the event of a dispute
between the Company and a party, the Trustee may apply to a court of
competent jurisdiction to resolve the dispute.

     (b)  If the Trustee undertakes or defends any litigation arising
in connection with this Trust, the Company agrees to indemnify the
Trustee against the Trustee's reasonable costs, expenses and liabili-
ties (including, without limitation, attorneys' fees and expenses)
relating  thereto  and  to  be  primarily  liable  for  such  payments;
provided that the Trustee must first afford the Company the opportuni-
ty to defend any action against the Trust or the Trustee in connection
with this Trust.

      (c) The Trustee may consult with legal counsel (who may also be
counsel for the Company generally) with respect to any of its duties
or obligations hereunder.

     (d)  The  Trustee  may  hire  agents,  accountants,  actuaries,
investment advisors, financial consultants or other professionals to
assist it in performing any of its duties or obligations hereunder.

(e)  The  Trustee  shall  have,  without  exclusion,  all  powers conferred on
trustees by applicable law, unless expressly provided otherwise herein;
provided, however, that if an insurance policy is held as an asset of the Trust,
the Trustee shall have no power to name a beneficiary of the policy other than
the Trust, to assign the policy (as distinct from conversion of the policy to a
different form) other

                                        8


<PAGE>

than to a successor Trustee, or to loan to any person the proceeds of any
borrowing against such policy.

      (f)  Notwithstanding any powers granted to the Trustee pursuant
to this Trust Agreement or to applicable law, the Trustee shall not
have any power that could give this Trust the objective of carrying on
a business and dividing the gains therefrom, within the meaning of
Section 301.7701-2 of the Procedure and Administrative Regulations
promulgated pursuant to the Internal Revenue Code.

SECTION 9.  COMPENSATION AND EXPENSES OF TRUSTEE.

     The Company, or at its option, the Trust, shall quarterly pay the Trustee
its  expenses  in  administering  the  Trust  and  reasonable compensation for
its services as Trustee at a rate to be agreed upon from time to time by the
parties to this Trust Agreement, based upon Trustee's  published  fee  schedule.
 Reasonable  compensation  shall include compensation for any extraordinary
services or computations required.    The  Trustee  shall  have  a  lien  on
the  Trustee  for compensation  and  for  any  reasonable  expenses  including
counsel, appraisal, or accounting fees, and these may be withdrawn from the
Trust unless paid by the Company within 30 days after mailing of the written
billing by the Trustee.

SECTION 10.  RESIGNATION AND REMOVAL OF TRUSTEE; APPOINTMENT OF
             SUCCESSOR.

      (a)  The Trustee may resign at any time by written notice to
Company, which shall be effective 30 days after receipt of such notice
unless the Company and the Trustee agree otherwise.  If the Trustee
resigns at any time after a Change in Control, the Company shall
appoint a successor Trustee which must be approved by Eric Lidow or,
if he is then deceased, his surviving spouse.

      (b)  The Trustee may be removed by the Company on 30 days' notice
or upon shorter notice accepted by the Trustee; provided that, after
a Change in Control, the Trustee may not be removed by the Company
unless such removal is approved by Eric Lidow or,  if he is then
deceased, his surviving spouse.

(c)  Any successor Trustee may be a bank trust department or other party that
may be granted corporate trustee powers under state law.  Upon resignation or
removal of the Trustee and appointment of a successor Trustee, all assets shall
subsequently be transferred to the successor Trustee.  The transfer shall be
completed within 30 days after receipt of notice of resignation, removal or
transfer, unless the Company extends the time limit; provided that after a
Change in Control any extension must be approved by Eric Lidow or, if he is then
deceased, his surviving spouse.  Notwithstanding the foregoing, the Trustee
resigning or  being removed is authorized to reserve such amount of trust assets
as may be necessary for the payment of its fees and expenses incurred prior to
its resignation, and the Trust assets

                                        9

<PAGE>

shall remain liable to reimburse the resigning Trustee for all costs, expenses
or attorneys' fees or losses incurred, whether before or after  resignation,
due  solely  to  Trustee's  holding  title  to  and administration of Trust
assets.

      (d)  A successor Trustee must be appointed by the effective date
of  resignation  or  removal  of  the  original  Trustee.   If  no  such
appointment has been made, the original Trustee may apply to a court
of  competent  jurisdiction  for  appointment  of  a  successor  or  for
instructions.   All expenses of the Trustee in connection with the
proceeding shall be allowed as administrative expenses of the Trust.
The Trustee shall continue to be entitled to compensation for its
services as provided herein as Trustee until a successor Trustee is
appointed.

      (e)  The successor Trustee need not examine the records and acts
of any prior Trustee and may retain or dispose of existing Trust
assets, subject to Sections 5, 7 and 8 hereof.  The successor Trustee
shall not be responsible for and the Company shall indemnify and
defend the successor Trustee from any claim or liability resulting
from any action or inaction of any prior Trustee or from any other
past event, or any condition existing at the time it becomes successor
Trustee.

SECTION 11.  AMENDMENTS OR TERMINATION.

     (a)  This Trust Agreement may be amended by a written instrument executed
by the Trustee and the Company, provided that after a Change in Control any
amendment of this Agreement must be approved by Eric Lidow or, if he is then
deceased, his surviving spouse.   Notwithstanding the foregoing, no such
amendment shall conflict with the terms of the Employment Agreement or shall
make the Trust revocable.

     (b)  The Trust shall not terminate until the date on which Eric
Lidow and his spouse are no longer entitled to benefits pursuant to
the terms of the Employment Agreement.  Such date shall be determined
by the Company and communicated to the Trustee in writing.   Upon
termination of the Trust, any assets remaining in the Trust shall be
returned to the Company.

     (c)  Notwithstanding the foregoing, the Company may terminate the Trust
upon (i)  written approval of Eric Lidow or,  if he is then deceased, his
surviving spouse, (ii) the exhaustion of all appeals of a final determination of
a court of competent jurisdiction that the interests in the Trust of Eric Lidow
or his spouse is includible for federal income tax purposes in his or her gross
income, without such determination having been reversed (or the earlier
expiration of the time to appeal), (iii) the expiration of the maximum length of
time for which trusts may be established under any applicable state law, (iv) a
determination of the Company to terminate the Trust because of applicable law
requires it to be amended in a way that could make it taxable to Eric Lidow or
his spouse and failure to so amend the Trust would  subject  the  Company  to
material  penalties,  or  (v)  a

                                       10

<PAGE>

determination  of  the  Company  to  terminate  the  Trust  because  the Company
concludes, after consulting with legal counsel, that judicial authority or the
opinion of the U.S. Department of Labor (as expressed in its proposed or final
regulations, advisory opinions, or similar administrative announcements) creates
a significant possibility that the Trust will not be considered a component of
an unfunded plan or arrangement maintained primarily to provide deferred
compensation for a  member  of  a  select  group  of  management  or  highly
compensated employees, as described in Section 201(2) of the Employee Retirement
Income Security Act of 1974, as amended.  All assets in the Trust at termination
shall be returned to the Company.

SECTION 12.  MISCELLANEOUS.

     (a)  Any provision of this Trust Agreement prohibited by law
shall be ineffective to the extent of any such prohibition, without
invalidating the remaining provisions hereof.

     (b)  Benefits payable to Eric Lidow or his spouse under this
Trust Agreement may not be anticipated, assigned (either at law or in
equity), alienated, pledged, encumbered or subjected to attachment,
garnishment, levy, execution or other legal or equitable process.

     (c)  This Trust Agreement shall be governed by and construed in
accordance with the laws of California.

     (d)  This instrument may be executed in one or more counterparts,
each of which is legally binding and enforceable.

     (e)  Terms used in the masculine shall include the feminine and
vice versa and terms used in the singular shall include the plural and
vice versa, unless the context clearly indicates otherwise.

     (f)  This Trust Agreement shall inure to the benefit of, and be
binding upon, the parties hereto and their successors and assigns.

     (g)  Any dispute under this Agreement between Company and Trustee
shall be resolved by submission of the issue to a member of the
American Arbitration Association who is chosen by the Company and the
Trustee.  If the Company and the Trustee cannot agree on the choice,
each shall nominate a member of the American Arbitration Association,
and the two nominees will then select an arbitrator.

     IN WITNESS WHEREOF, this Trust Agreement is executed this 24th day of

     the trustee. It is proposed to amend the trust, as permitted by
     Section 11(a) thereof, as follows:

     Section 1(e) is deleted in its entirety and replaced with:

          the Company shall irrevocably deposit an additional $1,040,000.
          Thereafter, within 30 days following the end of each calendar quarter,
          the Company shall irrevocably deposit an amount equal to the quarterly
          pro-rata (straight-line) liability accrual during the current fiscal
          year of the Company, as  determined by Coopers & Lybrand as part of
          its annual audit of International Rectifier Corporation, with respect
          to the retirement benefits payable to Eric Lidow and his wife as of
          the termination date of the Employment Agreement (June 30, 1997) or

    Borrower further agrees to pay interest (whether before or after any breach

also be payable on any overdue payment of principal and (to the extent permitted
by law) interest as set forth in the Credit Agreement (as defined below).

    With respect to each interest rate selection by Borrower, the date,

NationsBank  on the reverse of this Note or on such schedules as NationsBank

may be endorsed on this Note from time to time by NationsBank.  Notwithstanding

(as defined in the Credit Agreement), shall not at any time exceed the maximum

    Interest accrued on this Note shall be due and payable as provided in the
Credit Agreement.  The outstanding principal balance of this Note, together with

Note, including, but not limited to, any action for declaratory relief.

                                    THE TERM LOAN

         2.01  TERM LOAN.  Subject to the terms and conditions of this
Agreement, the Bank hereby agrees to lend to the Borrower, upon the Borrower's
request which shall be made after June 12, 1996 for drawdown as of June 14,
1996, and prior to June 30, 1997 (the "Drawdown Period") in minimum amounts of
$5,000,000.00 up to the maximum amount of $20,000,000.00 (the "Term Loan");
provided that a borrowing may be made in an amount equal to any remaining
portion of the Term Loan.  The Borrower shall provide the Bank with a written
request at least two (2) Business Days prior to the date of a proposed borrowing
(no later than 11:30 a.m. (California time)) specifying (a) the date of the
borrowing, (b)


                                         -7-

<PAGE>

the amount of the borrowing, and (c) the Interest Period.  The Term Loan shall
be evidenced by the Note.  Any amount prepaid or repaid may not be reborrowed
under this Agreement.

         A.  Term Loan Account.  The Bank shall maintain on its books a record
of account in which the Bank shall make entries setting forth all payments made,
the application of such payments to interest and principal, accrued and unpaid
interest (if any) and the outstanding principal balance under the Term Loan (the
"Term Loan Account").  The Bank shall provide the Borrower with a monthly
statement of the Borrower's principal amount outstanding hereunder, which
statement shall be conclusive and binding upon the Borrower absent manifest
error.

         B.  Interest.

             (a)  Effective June 14, 1996, interest shall accrue on the
outstanding principal balance or any portion of the outstanding principal
balance on the Term Loan ("Term Balance") at a rate of LIBOR plus a margin of 
0.65% per annum (the "LIBOR Rate").  The interest period with respect to the
LIBOR Rate shall be a period of one (1), three (3) or six (6) months, at the
Borrower's option, thereafter (the "Interest Period"), beginning on the
borrowing date, the conversion date or the last day of the immediately preceding
Interest Period, as the case may be.  Each determination of LIBOR applicable to
a particular Interest Period


                                         -8-

<PAGE>

shall be made by the Bank and shall be conclusive and binding upon the Borrower
absent manifest error.  Prior to the end of each Interest Period, the Borrower
shall select the applicable Interest Period for the Term Loan in a written
notice to the Bank.  Each such notice shall be delivered to the Bank no later
than 11:30 a.m. (California time), at least two (2) Business Days prior to the
end of the then current Interest Period.  If the Borrower shall at any time fail
to send to the Bank such notice in a timely manner, then the Borrower shall be
deemed to have elected an Interest Period of one (1) month.  Term Balances based
upon the LIBOR Rate is hereinafter referred to as the "Eurodollar Balances".

              (b)  Effective June 14, 1997, the Borrower has the option to
convert the Eurodollar Balances, in whole or in part, to Fixed Rate Balances
pursuant to the terms and conditions set forth below.  The Term Balance shall
bear interest at the Bank's cost of funds to be determined two (2) Business Days
prior to conversion plus a margin of 0.70% per annum (the "Fixed Rate").  The
Bank shall provide the Borrower with a statement of the Borrower's Fixed Rate,
which statement shall be considered to be correct and conclusively binding on
the Borrower absent manifest error.  The Term Balance bearing interest at the
Fixed Rate is hereinafter referred to as "Fixed Rate Balances".


                                         -9-

<PAGE>

    Should the Borrower decide to elect the Fixed Rate, the Borrower shall 
convert, in whole or in part, on the last day of any Interest Period in a 
minimum amount of $2 Million up to the total amount of principal 
outstanding as of June 30, 1997. The Borrower shall deliver a written notice 
to the Bank specifying (a) the date of the conversion, (b) the amount of the 
conversion and (c) the Fixed Rate term period (the "Fixed Rate Term Period"). 
Each such notice shall be delivered to the Bank no later than 11:30 a.m. 
(California time), at least two (2) Business Days prior to the date of 
conversion.

    On any date of determination, the Term Balance shall never exceed the 
Term Balance as of June 30, 1997, minus the sum of (i) all scheduled 
payments to be made through such date of determination plus (ii) all 
prepayments made on the Term Balance. The Fixed Rate Term Period selected by 
the Borrower shall not extend beyond any Repayment Dates (as hereinafter 
defined) unless the Term Balance, the aggregate amount of which shall be equal 
to or greater than the amount to be repaid on any particular Repayment Date, 
shall become due and payable on such Repayment Date.

              (c)  The Borrower has the option to convert from the Fixed Rate 
to the LIBOR Rate, in whole, on the last day of any Fixed Rate Term Period. The 
Borrower shall deliver a written notice to the Bank specifying (a) the date 
of the


                                      -10-


<PAGE>

conversion, and (b) the Interest Period. Each such notice shall be 
delivered to the Bank no later than 11:30 a.m. (California time), at least 
two (2) Business Days prior to the date of conversion.

              (d)  Interest on any Eurodollar Balance with an interest period 
of 93 or less days shall be paid on the last day of the relevant Interest 
Period pertaining to such Eurodollar Balance. Interest on any Eurodollar 
Balance with an Interest Period in excess of 93 days shall be paid quarterly 
(i.e., on the last day of each 3 month period occurring in such Interest 
Period) and on the last day of the relevant Interest Period pertaining to 
such Eurodollar Balance.

    Interest on any Fixed Rate Balance for each advance shall be paid 
quarterly (i.e., on the day that is three months after the relevant conversion 
date and every three months thereafter).

    Interest shall be calculated on a year of 360 days for actual days elapsed.

              (e)  Notice of Election to Adjust Interest Rate. Upon written 
notice which shall be received by the Bank at or before 11:30 a.m. (California 
time) on a Business Day, the Borrower may elect that interest on a 
Eurodollar Balance shall


                                     -11-


<PAGE>

continue to accrue at a newly quoted LIBOR Rate or shall be adjusted to 
commence to accrue at the Fixed Rate; provided, however, that such notice 
shall be received by the Bank no later than two (2) Business Days prior to 
the last day of the Interest Period. If the Bank shall not have received 
notice as prescribed herein of Borrower's election that interest on any 
Eurodollar Balance shall continue to accrue at the LIBOR Rate, Borrower shall 
be deemed to have elected that interest thereon shall be adjusted to accrue 
at the newly quoted LIBOR Rate with the one (1) month Interest Period upon the 
expiration of the Interest Period pertaining to such Eurodollar Balance.

              (f)  Optional Prepayment. Notwithstanding anything to the 
contrary in this Agreement, the Borrower may from time to time prepay any 
Eurodollar Balance, in whole or in part, without premium or penalty; provided 
that any such payment shall be on a day which is the last day of the relevant 
Interest Period. The Borrower may prepay any Fixed Rate Balance, in whole 
or in part, without premium or penalty; provided that the Borrower shall pay 
the Bank on the date of the prepayment for any and all of the breakage costs 
incurred by the Bank due to such prepayment which breakage costs shall be 
determined by the Bank in its reasonable discretion which determination 
shall be conclusive absent manifest error.


                                     -12-


<PAGE>

         If the whole or any part of the Term Balance is prepaid by reason of
acceleration or otherwise, the Borrower shall upon the Bank's request, pay to
and indemnify the Bank for all costs and any loss (including interest) actually
incurred by the Bank and any loss (excluding loss of profit resulting from the
re-employment of funds) sustained by the Bank as a consequence of such
prepayment.  Any prepayment shall first be applied to pay accrued interest, then
be applied to reduce the principal balance payable on the date set forth in this
Agreement, and the remaining portion (if any) of such prepayment shall then be
applied to pay the principal installment(s) of latest maturity under this Term
Loan.

              (g)  Increased Costs.  The Borrower shall within five (5) 
Business Days after written notice from the Bank, reimburse the Bank for any 
increased cost incurred by the Bank in making or maintaining the Term Loan, 
including, but without limitation the Bank's cost of maintaining any reserves 
or special deposits against the Term Loan or against the deposits to fund the 
Term Loan or of complying with any Applicable Laws after the date hereof 
with respect to the Term Loan or with respect to any other aspect of this 
transaction, including but not limited to, costs or reductions in the Bank's 
return on capital resulting from changes in capital adequacy requirements.  
The Bank shall submit to the Borrower a certificate setting forth the amount 
of any such increased cost and describing in reasonable detail the 


                                         -13-

<PAGE>

basis and calculation of such increased costs which in the absence of manifest
error shall be conclusive and binding.  The foregoing notwithstanding, (i) the
Borrower shall not be responsible for payment of any amounts to the extent
determined to be as a result of the Bank's gross negligence or willful
misconduct, and (ii) the Bank shall use its reasonable efforts (consistent with
its internal policy and legal and regulatory restrictions) to take any action if
the taking of such action would avoid the need for, or reduce the amount of, any
additional amounts payable and would not, in the reasonable judgment of the
Bank, be otherwise disadvantageous to the Bank.

              (h)  Illegality.  In the event it becomes unlawful for the Bank 
to make or maintain the Term Loan at the LIBOR Rate or any advance of the Term 
Loan at the LIBOR Rate, then the obligation of the Bank to make the Term Loan 
at the LIBOR Rate or any such advance at the LIBOR Rate shall forthwith 
terminate or, if the entire amount of the Term Loan at the LIBOR Rate has 
already been advanced, then upon notice by the Bank the Term Loan shall 
immediately bear interest at a rate per annum equal to the sum of the Bank's 
cost of funds, as determined by the Bank at its sole discretion, plus 
0.65 percent.

              (i)  Business Day Adjustment.  If the date on which a payment 
hereunder is due is not a Business Day or if any Interest Period would 
otherwise end on a day that is not a 


                                         -14-

<PAGE>

Business Day, then such payment shall be made, or such Interest Period shall
end, on the next succeeding Business Day; provided however, in the event the
Interest Rate is based on the LIBOR Rate, the Interest Period shall end on the
immediately preceding Business Day if the next succeeding Business Day is in
another calendar month.

              (j)  Taxes.  Any and all payments by the Borrower hereunder or 
under the Note shall be made free and clear or and without deduction for 
any taxes.

         C.   Principal.  The Borrower hereby promises and agrees to pay
the outstanding principal of the Term Loan in 6 equal semi-annual installments
of the outstanding principal balance of the Term Loan commencing on December 1,
1998, and ending on June 1, 2001 ("Repayment Dates").

         Each payment received by the Bank shall be applied to pay interest
then due and unpaid and the remainder thereof (if any) shall be applied to pay
principal.

         D.  Commitment Fee.  Borrower agrees to pay to the Bank a
commitment fee during the Drawdown Period of 0.25% per annum on the daily
average undrawn portion of the Term Loan, payable quarterly in arrears and
computed on a year of 360 days for actual days elapsed.

                                 THE TERM LOAN

     2.1  TERM LOAN.  The Bank agrees to lend to the Borrower in up to 5 
drawings in the minimum amount of $1,000,000, upon the Borrower's request 
made prior to June 30, 1997, (the "Drawdown Period") up to the maximum amount 
of $20,000,000 (the "Term Loan").

          (a)  PURPOSE.  Proceeds from the Term Loan shall be used to finance 
capital expenditures.

          (b)  TERM LOAN AMOUNT.  The Bank shall maintain on its books 
a record of account in which the Bank shall make entries setting forth all 
payments made, the application of such payments to interest and principal, 
accrued and unpaid interest (if any) and the outstanding principal balance 
under the Term Loan (the "Term Loan Account").  The Bank shall provide the 
Borrower with a monthly statement of the Borrower's Term Loan Account, which 
statement shall be considered to be correct and conclusively binding on the 
Borrower, absent manifest error.

          (c)  INTEREST.

               A.  LIBO RATE.  Interest shall accrue on the outstanding 
principal balance or any portion of the outstanding principal balance of the 
Term Loan at a fixed rate quoted by the Bank for a minimum of one month or 
for such other period of time that the Bank may quote and offer (the "Interest 
Period") for Term Balances in the minimum amount of $100,000.  Such interest 
rate shall be a percentage equivalent to .55% per annum in excess of the Bank's 
LIBO Rate which is that rate determined by the Bank at which U.S. dollar 
deposits for the relevant Interest Period and in the approximate amount of the 
relevant Term Balance would be offered by the Bank to prime banks in the London 
interbank market as of 11:00 A.M. (London time) on the day which is two LIBO 
Business Days prior to the first day of such Interest Period (adjusted for any 
and all assessments, surcharges and reserve requirements pertaining to the 
purchase by the Bank of such U.S. dollar deposits) (the "LIBO Rate").

     Interest on any Term Balance with an Interest Period of 93 or less days 
shall be paid on the last day of the relevant Interest Period pertaining to such
Term Balance.  Interest on


                                      -3-


<PAGE>

any Term Balance with an Interest Period in excess of 93 days shall be paid 
quarterly (i.e., on the last day of each 3 month period occurring in such 
Interest Period) and on the last day of the relevant Interest Period 
pertaining to such Term Balance.

     Interest shall be calculated on a year of 360 days for actual days 
elapsed.

          B.  PREPAYMENT. Notwithstanding anything to the contrary in the 
Agreement, no prepayment shall be made on any Term Balance except on a day 
which is the last day of the relevant Interest Period pertaining thereto. If
the whole or any part of any Term Balance is prepaid by reason of 
acceleration or otherwise, the Borrower shall upon the Bank's request, 
promptly pay to and indemnify the Bank for all costs and any loss (including 
interest) actually incurred by the Bank and any loss (excluding loss of profit 
resulting from the re-employment of funds) sustained by the Bank as a 
consequence of such prepayment. Any prepayment shall first be applied to pay 
accrued interest, then be applied to pay the principal installment(s) of 
latest maturity under this Term Loan.

          C.  INDEMNIFICATION FOR LIBO RATE COSTS. The Borrower shall, upon 
the Bank's written request, which request shall explain in reasonable detail 
the reason for such costs or payments, promptly pay to and reimburse the 
Bank for all costs incurred and payments made by the Bank by reason of any 
future assessment, reserve, deposit or similar requirements or any surcharge, 
tax or fee imposed upon the Bank or as a result of the Bank's compliance with 
any directive or requirement of any regulatory authority pertaining or 
relating to funds used by the Bank in quoting and determining the LIBO Rate.

     (d)  PRINCIPAL. The Borrower hereby promises and agrees to pay the 
outstanding principal of the Term Loan in 12 equal quarterly installments of 
1/12th of the outstanding principal balance of the Term Loan as of June 30, 
1997 commencing on September 30, 1998 and continuing on the last day of each 
calendar quarter thereafter up to and including June 30, 2001. On June 30, 
2001, the Borrower hereby promises and agrees to pay to the Bank the entire 
unpaid principal balance, together with accrued and unpaid interest.

     Each payment received by the Bank shall be applied to pay interest then due
and unpaid and the remainder thereof (if any) shall be applied to pay 
principal.

     (e)  COMMITMENT FEE.  The Borrower agrees to pay to the Bank a 
commitment fee during the Drawdown Period of .25% per annum on the undrawn 
portion of the Term Loan, payable quarterly in arrears and computed on a 
year of 360 days for actual days elapsed.


                                       -4-

     2.2 LIMITATIONS.

     (a) Notwithstanding anything to the contrary herein, the Borrower shall 
not be required to make any payment to the Bank with respect to any indemnity 
required pursuant to Sections 2.1(c).C ("Affected Section") unless the Bank 
shall have given notice to the Borrower promptly upon the Bank becoming aware 
of any circumstance requiring the Borrower to make any payment under an 
Affected Section.

     (b) The Borrower shall not be responsible for payment of any amounts 
payable under any Affected Section to the extent determined to be as a result 
of the Bank's gross negligence or willful misconduct.

     (c) The Bank shall use its reasonable efforts (consistent with its 
internal policy and legal and regulatory restrictions) to take any action if 
the taking of such action would avoid the need for, or reduce the amount of, 
any additional amounts payable under any Affected Section and would not, in 
the reasonable judgment of the Bank, be otherwise disadvantageous to the Bank.

                                    SECTION 3
