ITEM 1. Business

General

   The Company is a vertically integrated worldwide provider of devices,
subsystems and end-products based on optoelectronic and silicon pressure-sensor
microstructure technology. The Company designs and manufactures optoelectronic
and silicon pressure-sensor devices and value-added subsystems for original
equipment manufacturers ("OEMs") for use in a broad range of applications,
including security, medical diagnostics, telecommunications, gaming, office
automation, aerospace, computer peripherals and industrial automation. In
addition, the Company utilizes its optoelectronic technology and design
capabilities to manufacture security and inspection products that it markets
worldwide to end users under the "Rapiscan," "Secure" and "Metor" brand names.
These products are used to inspect people, baggage, cargo and other objects for
weapons, explosives, drugs and other contraband. The Company has also, through
the acquisition of Osteometer MediTech A/S ("Osteometer"), expanded into the
manufacture and sale of bone densitometers, which are used to provide bone loss
measurements in the diagnosis of osteoporosis. In fiscal 1999, revenues from
the sale of optoelectronic and silicon pressure-sensor devices and subsystems
and medical imaging systems amounted to $55.5 million, or approximately 54.5%
of the Company's revenues, while revenues from sales of security and inspection
products amounted to $46.3 million, or approximately 45.5% of the Company's
revenues. Unless the context otherwise requires, the term the "Company" as used
herein includes OSI Systems, Inc., a California corporation, and its
subsidiaries.

Industry Overview

   The Company's optoelectronic and silicon pressure-sensor devices and
subsystems are designed and manufactured primarily for sale to OEMs, while the
Company's security products and medical imaging systems are sold to end-users.

   Optoelectronic and Silicon Pressure-Sensor Devices and
Subsystems. Optoelectronic devices consist of both active components, such as
silicon photodiodes that sense light of varying wavelengths and convert the
light detected into electronic signals, and passive components, such as lenses,
prisms, filters and mirrors. An optoelectronic subsystem typically consists of
one or more optoelectronic devices that are combined with other electronic
components for integration into an end-product. Optoelectronic devices and
subsystems, and medical imaging systems, are used for a wide variety of
applications ranging from simple functions, such as the detection of paper in
the print path of a laser printer, to complex monitoring, measurement or
positioning functions, such as in industrial robotics where the subsystem is
used to detect the exact position, motion or size of another object. Because
optoelectronic devices and subsystems can be used in a wide variety of
measurement, control and monitoring applications, optoelectronics may be used
in a broad array of industrial applications.

   The Company believes that in recent years advances in technology and
reductions in the cost of key components of optoelectronic systems, including
computer processing power and memory, have broadened the market by enabling the
use of optoelectronic devices in a greater number of applications. In addition,
the Company believes that there is a trend among OEMs to increasingly outsource
the design and manufacture of optoelectronic subsystems to fully integrated,
independent manufacturers who may have greater specialization, broader
expertise, and the ability and flexibility to respond in shorter time periods
than the OEM could accomplish in-house. The Company believes that its high
level of vertical integration, substantial engineering resources, expertise in
the use and application of optoelectronic technology, and low-cost
international manufacturing operations enable it to compete in the market for
optoelectronic devices and subsystems.

   Silicon pressure sensors and microstructures are based upon the same process
technologies as the optoelectronic components and are also used as components
in a variety of applications primarily in the

                                       1
<PAGE>

automotive, medical, and industrial markets. Typical applications include
pressure sensing in fuel vapor systems, engine controls, respiration and
aneasthesia machines, and industrial pressure transducers, and heating, venting
and air-conditioning markets. The Company sells its products in die form to
other sensor companies as well as packaged parts. A primary focus of the
companies' pressure products has been in the precision low-pressure segment of
the silicon sensor market, where the performance of its parts allow replacement
of non-silicon sensors with lower cost silicon components.

   Security and Inspection Products. A variety of products are currently used
worldwide in security and inspection applications. These products include
single energy x-ray equipment, dual energy x-ray equipment, metal detectors,
trace detection systems that detect particulate and chemical traces of
explosive materials, computer tomography ("CT"), scanners and x-ray machines
employing backscatter detection technology. To date, most of these products
have been deployed primarily at commercial airports worldwide. The Company
believes that the growth in the market for security and inspection products
will continue to be driven by the increased perception of threat fueled by
recent terrorist incidents, increased government mandates and appropriations,
and the emergence of a growing market for the non-security applications of its
products.

   In the 1970s, principally in response to civilian airline highjackings, the
U.S. Federal Aviation Administration ("FAA") established security standards by
setting guidelines for the screening of carry-on baggage for weapons such as
guns and knives. These standards were later mandated by the United Nations for
adoption by all of its member states. The Company believes that to date the
imposition of these standards has resulted in the installation of over 10,000
x-ray inspection systems installed in airports worldwide. Additionally, the
United Kingdom Department of Transport has required the United Kingdom's
commercial airports to deploy systems for 100% screening of international
checked baggage since the end of 1998, and the European Civil Aviation
Conference, an organization of 33 member states, has agreed to implement 100%
screening of international checked baggage in the future. In the United States,
largely in response to the explosion of Pan Am Flight 103 in December 1988,
Congress enacted the Aviation Security Improvement Act of 1990 which, among
other initiatives, directed the FAA to establish and implement strict security
measures and to deploy advanced technology for the detection of various
contraband, including explosives, drugs, and currency. In July 1996, President
Clinton formed the White House Commission on Aviation Safety and Security (the
"Gore Commission"), to review airline and airport security and to oversee
aviation safety. In response to the initial report released by the Gore
Commission, the United States enacted legislation that includes $144 million in
appropriations for the initial deployment of advanced security and inspection
technology at major U.S. airports. The Clinton Administration is continuing to
fund procurements of $100 million annually for state-of-the-art detection
equipment at major U.S. airports. A portion of this funding is allocated for
TIP Ready X-ray (TRX) systems at security checkpoints throughout the nation.
Rapiscan, through FAA funding, has deployed some 40 TIP systems in the last two
years and is currently one of the vendors being evaluated for procurement
decisions.

   X-ray inspection equipment, such as that sold by the Company, is also
increasingly being used for a number of purposes not related to security. Newer
versions of x-ray inspection equipment combine x-ray inspection with computer
image enhancement capabilities and can be applied to various non-security
purposes such as the detection of narcotics, gold and currency, the inspection
of agricultural products, and the inspection of cargo by customs officers and
international shippers.

Growth Strategy

   The Company's objectives are to be a leading provider of specialized
optoelectronic and silicon pressure-sensor products, to enhance its position in
the international inspection and detection marketplace and to leverage its
expertise in the optoelectronic technology industry by entering into new end-
product markets on a selective basis. Key elements of this strategy include:

   Leverage its Optoelectronic Design and Manufacturing Expertise to Address
New Applications. The Company believes that one of its primary competitive
strengths is its expertise in designing and manufacturing

                                       2
<PAGE>

specialized optoelectronic subsystems for its OEM customers in a cost-effective
manner. The Company currently designs and manufactures devices and subsystems
for over 200 customers serving over 100 applications. The Company has developed
this expertise in the past through internal research and development efforts
and through selective acquisitions. In 1990, the Company acquired UDT Sensors,
Inc. ("UDT Sensors") to broaden its expertise and capabilities in developing
and manufacturing optoelectronic devices and subsystems. In 1993, the Company
acquired Rapiscan Security Products Limited ("Rapiscan U.K.") and, through
Rapiscan Security Products (U.S.A.), Inc. ("Rapiscan U.S.A.") (Rapiscan U.S.A.
and Rapiscan U.K. are sometimes collectively referred to as "Rapiscan"),
commenced its operations as a provider of security and inspection products in
the United States. Thereafter, in 1993, the Company acquired Ferson Optics,
Inc. ("Ferson Optics") for its passive optic technologies. In 1994, the Company
commenced operations of Opto Sensors (Malaysia) Sdn. Bhd. ("OSI Malaysia") to
take advantage of low cost manufacturing. In 1997, the Company acquired
Advanced Micro Electronics AS ("AME") for AME's hybrid optoelectronic
capabilities.

   In September 1998, the Company acquired Osteometer, a Danish manufacturer of
diagnostic scanners used to detect osteoporosis. The Company paid $7.9 million
in cash, including professional fees associated with the acquisition.
Osteometer concentrates on the development of small, cost optimized scanners
making it possible for small clinics to offer their patients a cost effective
diagnosis of osteoporosis and is committed to the development of scientifically
and clinically validated devices that result in accurate, precise, reliable and
cost effective diagnosis. Due to the global decline in the bone densitometer
market, the Company recently announced the closure of Osteometer's
manufacturing facilities in Denmark. Currently, the Company intends to relocate
certain of these operations to the United States over the next several months.
The Company expects to incur additional expenses in connection with the
discontinuation of those operations and their intended relocation to the United
States, which will be recorded in future periods. The osteoporosis industry is
currently weak and is expected to remain so for at least the near-term.

   In November 1998, the Company purchased the security products business of
Metorex International Oy ("Metorex Security") of Espoo, Finland. The Company
paid $4.7 million in cash, including professional fees associated with the
acquisition. In July 1999, the Company paid 4.4 million Finnish markka
(approximately $759,000), in lieu of contingent payments of up to $1.5 million,
based on future sales.

   The acquisition of Metorex Security brings a complete security metal
detection product line to the Company. "Metor" brand security archway metal
detectors are among the most widely recognized such products in the world.
These metal detectors complement the x-ray screening systems supplied by
Rapiscan. Metorex Security continues to supply a large number of systems to the
U.S. Government, as well as to customers around the world. The products include
Metor 100 series archways, as well as Metor 200 series zonal archways. The
Company's MetorNet(TM) product allows monitoring and control of multisystem
installations.

   In November 1998, the Company acquired all the outstanding stock of Silicon
Microstructures, Inc. ("SMI"), a silicon pressure-sensor manufacturer, from
Exar Corporation of Fremont, California. The Company paid $2.7 million in cash,
including professional fees associated with the acquisition. The Company may
pay up to an additional $3.9 million in cash, at a later date, based on future
sales. The designs and processes of SMI allow leveraging of the Company's
silicon wafer fabrication technologies to initially serve pressure-sensor
markets and extend into the future to a variety of products based on mechanical
structures in silicon.

   In December 1998, the Company acquired most of the assets and assumed
certain liabilities of Corrigan Canada Ltd. ("Corrigan"), a Canadian security
products manufacturer, for approximately $476,000 in cash, including
professional fees associated with the acquisition.

   In January 1999, the Company acquired Aristo Medical Products, Inc.
("Aristo") for approximately $277,000 in cash, including professional fees
associated with the acquisition. Aristo develops and manufactures new
generation pulse oximeter probes used in the medical field.

   In August 1998, the Company invested $315,000, including professional fees
associated with the acquisition, in Square One Inc. ("Square One") for an
equity share of approximately 16%. Square One develops and manufactures
infrared-based patient monitoring medical subsystems.

                                       3
<PAGE>

   During fiscal 1999, the Company invested $1,002,000, including professional
fees associated with the acquisition, in TFT Medical, Inc. ("TFT Medical")
(formerly known as Physiometrics, Inc.) for an equity share of approximately
40%. TFT Medical develops new generation pulse oximeter instruments and probes
for use in the medical field.

   The Company intends to continue to build this expertise in order to address
a greater number of applications. By expanding the number of potential
applications its products may serve, the Company intends to increase its
business with existing customers and attract new customers.

   Further Penetrate Existing Security and Inspection Markets and Expand into
Other Markets. For the year ended June 30, 1999, the Company continued to
expand sales of its security and inspection products beyond the traditional
focus on airports and airlines to include government buildings, customs
facilities, courthouses, school districts, departments of corrections and
businesses for their respective security and inspection needs. The Company
intends to continue to expand its sales and marketing efforts both domestically
and internationally to capitalize on opportunities in its existing markets for
new installations as well as opportunities to replace, service and upgrade
existing security installations. In addition, through research and development
and selective acquisitions, the Company intends to enhance and expand its
current product offering to better address new applications including automatic
bomb detection and cargo scanning.

   The Company believes that its strategy will enable it to take advantage of
the growth its existing markets are experiencing and to benefit from additional
growth that these new and enhanced products will provide.

   Capitalize on Vertical Integration. The Company believes that it offers
significant added value to its OEM customers by providing a full range of
vertically integrated services including component design and customization,
subsystem concept design and application engineering, product prototyping and
development, and efficient pre-production, short-run and high volume
manufacturing. The Company believes that its vertical integration
differentiates it from many of its competitors and provides value to its OEM
customers, who can rely on the Company to be an integrated supplier of an
optoelectronic subsystem. In addition, the Company's vertical integration
provides several other advantages in both its optoelectronic devices and
subsystems and security and detection product lines. These advantages include
reduced manufacturing and delivery times, lower costs due to its access to
competitive international labor markets and direct sourcing of raw materials,
and quality control. Further leverage is obtained by extending the silicon
wafer fabrication processes to manufacture the pressure sensors and
microstructure processes of SMI. The Company intends to continue to leverage
its vertically integrated services to create greater value for its customers in
the design and manufacture of its products. The Company believes that this
strategy better positions the Company for penetration into other end markets.

   Capitalize on Global Presence. The Company operates from locations in the
United States, Europe, Asia and Canada. The Company views its international
operations as providing an important strategic advantage over competitors in
both the optoelectronic device and subsystem market and the security and
inspection market for three primary reasons. First, international manufacturing
facilities allow the Company to take advantage of competitive labor rates in
order to be a low cost producer. Second, its international offices strengthen
its sales and marketing efforts and its ability to service and repair its
systems by providing direct access to growing foreign markets and to its
existing international customer base. Third, multiple manufacturing locations
allow the Company to reduce delivery times to its global customer base. In the
future, the Company intends to develop new sources of manufacturing and sales
capabilities to maintain and enhance the benefits of its international
presence.

   Selectively Enter New End Markets. The Company intends to selectively enter
new end markets that complement its existing capabilities in designing,
developing and manufacturing optoelectronic devices and subsystems, such as the
expansion during fiscal 1998 into optoelectronic products for medical
diagnostic applications. The Company believes that by manufacturing other end
products which rely on the technological

                                       4
<PAGE>

capabilities of the Company, it can leverage its existing integrated design and
manufacturing infrastructure to capture greater margins and build a significant
presence in new end markets which present attractive competitive market
dynamics. The Company intends to achieve this strategy through internal growth
and through selective acquisitions of end-product manufacturers.

Products and Technology

   The Company designs, develops, manufactures and sells products based on its
core optoelectronic and silicon pressure-sensor technology. These products
range from discrete devices to value-added subsystems to complete x-ray
security and inspection products, and medical imaging systems.

   Discrete Devices and Subsystems, and Medical Imaging Systems. Optoelectronic
and silicon pressure-sensor devices generally consist of both active and
passive components. Active components sense light of varying wavelengths and
convert the light detected into electronic signals, whereas passive components
amplify, separate or reflect light. Active components manufactured by the
Company consist of silicon photodiodes and hybrid photodetectors. Passive
components include lenses, prisms, filters, mirrors and other precision optical
products that are used by the Company in the manufacture of its optoelectronic
products or are sold to others for use in telescopes, laser printers, copiers,
microscopes and other detection and vision equipment. A second group of
discrete devices are the pressure sensors and microstructures of SMI. These are
primarily manufactured in the same wafer fabrication facility as the
optoelectronic components, thereby achieving greater utilization and economy of
scale in this specialized facility. The same lithographic, furnace and metal
processes are combined with silicon etching to form precise miniature
electromechanical structures in silicon. SMI has developed specific structural
designs that concentrate stresses and provide higher signals and improved
performance over conventional silicon pressure sensors. The devices
manufactured by the Company are both standard products and products customized
for specific applications. Most of the devices manufactured by the Company are
incorporated by it into the subsystems that it manufactures. The Company does,
however, also sell its discrete devices separately to OEMs. Direct sales of
devices to third parties constituted less than 10% of the Company's revenues in
each of fiscal 1998 and fiscal 1999.

   In addition to the manufacture of discrete devices, the Company also
specializes in designing and manufacturing customized optoelectronic subsystems
for use in a wide range of products and equipment. An optoelectronic subsystem
typically consists of one or more optoelectronic devices that are combined with
other electronic components and packaging for use in an end-product. The
composition of a subsystem can range from a simple assembly of various
optoelectronic devices that are incorporated into other subsystems (for
example, a printed circuit board containing the Company's optoelectronic
devices), to complete end-products (for example, medical pulse oximeter probes
that are manufactured and packaged by the Company on behalf of the OEM customer
and then shipped directly to the customer or the customer's distributors).
Since the end of fiscal 1996, the Company has manufactured subsystems for a
variety of applications, including the following: imaging electronics for
medical CT scanners, disposable and reusable medical probes for use with
medical pulse oximetry equipment, components and subsystems for laser
gyroscopes used in military and commercial aviation, optoelectronic subsystems
for slot machines, laser subsystems in military helicopter gun sighting
equipment, positioning subassemblies for computer peripheral equipment,
alignment subsystems for laser heads in optical disc players, and ultra-violet
fire detection subsystems for submarines and surface ships.

   The Company has also moved into the field of manufacturing and selling the
DTX 200 (DEXACARE) and U.S. Food & Drug Administration ("FDA")-approved forearm
DEXA (Dual Energy X-Ray) densitometer, which is used to diagnose osteoporosis
as well as to provide follow-up bone density measurements. The Company also
produces the ultrasound DTU-One, the first commercially available scanner using
imaging capability for the diagnosis of osteoporosis. The DTU-One is currently
not available for sale in the United States, although the Company filed for
pre-market approval ("PMA") from the FDA in Spring 1998. It has been the
experience of the Company and other similarly situated companies that FDA
approval on PMAs for ultrasound devices can take 12 to 18 months from date of
submission on average, but this is an estimate only and the Company does not
know when the FDA process will be completed or what the outcome will be.

                                       5

   Security and Inspection Equipment. The Company manufactures and sells a
range of security and inspection equipment that it markets under the
"Rapiscan," "Secure" and "Metor" brand names. To date, the security and
inspection equipment has principally been used at airports to inspect carry-on
and checked baggage for guns and knives. However, inspection products are
increasingly being used for both security purposes at a wide range of
facilities other than airports and for other non-security purposes. For fiscal
years 1997, 1998 and 1999, approximately 27.3%, 22.0%, and 20.5% respectively,
of the Company's security and inspection revenues were derived from the sale of
inspection products to airlines and airports, and the balance of such revenues
were derived from all other sales.

   The Company's inspection and detection products combine the use of x-ray
technology with the Company's core optoelectronic capabilities. The base models
of its product line use single energy x-ray technology and are used for
identifying weapons with distinct shapes, such as guns and knives. The
Company's enhanced models combine dual- or multi-energy x-ray technology with
computer enhanced imaging technology to facilitate the detection of materials
such as explosives, narcotics, currency or other contraband. While all x-ray
systems produce a two-dimensional image of the contents of the inspected
material, the dual-energy x-ray systems also measure the x-ray absorption of
the inspected materials' contents at two x-ray energies to determine the atomic
number, mass and other characteristics of the object's contents. The different
organic and non-organic substances in the inspected material are displayed in
various colors. This information is then displayed to an operator of the
inspection equipment who can identify and differentiate the objects in the
inspected materials. These systems range in size from compact tabletop systems
to large cargo pallet inspection systems weighing over 100,000 lbs.

   Currently, all of the Company's inspection products require an operator to
monitor the images produced by the inspection equipment. Depending on the
model, the Company's products permit the operator to inspect the contents of
packages at varying image modes and magnifications. The images range from the
monochrome and pseudo-color images produced by single x-ray imaging systems, to
high resolution, multi-color images in the Company's computer enhanced dual-
energy models. The Company believes that its Rapiscan 500 Series provides one
of the highest quality images currently available in the x-ray security and
inspection industry.

   In the field of inspection of people, the Company's "Secure" brand product
line uses x-ray systems employing backscatter detection technology. Secure 1000
is an electronic screening system for hands off people screening. The system is
based on an extremely low dose of backscatter x-ray imaging to detect
contraband and weapons concealed underneath clothing and hair. The system
provides better screening than metal detectors as it detects very small amounts
of metal as well as non-metallic contraband.

   In order to monitor the performance of operators of the x-ray baggage
screening systems that are used in the United States airports, the FAA has
implemented a computer-based training and evaluation program known as the
Screener Proficiency Evaluation And Reporting System ("SPEARS"). To
continuously monitor the effectiveness of the screening system and its
operator, test threat images, such as weapons, are projected into the images of
actual parcels being inspected. The results of these tests are available to
government agencies. The FAA is currently evaluating TRX (TIP Ready X-Ray)
systems for procurement and deployment. The Company is participating as a
finalist in the initial phase of this procurement.

   During fiscal 1999, the Company entered into a number of significant
agreements for the sale of the Company's optoelectronic and silicon pressure-
sensor devices and subsystems. Some of the principal agreements are the
following.

   In fiscal 1998, the Company received a $2.3 million purchase commitment from
a U.S. defense systems manufacturer, for optoelectronic subsystems. These
subsystems were shipped during fiscal 1999 and will be finished shipping during
fiscal 2000.

   In August 1998, the Company entered into a Master Purchase Agreement with a
long-term customer, for $31.1 million of optical subsystems to be used in
medical products. Of this amount, $8.1 million represents a firm order received
in fiscal 1998, $4.4 million was received in fiscal 1999 and the rest is
cancellable based on convenience and other terms of the agreement. The
subsystems are being delivered over a four-year period.

   In September 1998, the Company received an order of approximately $10.0
million from the seismic services division of the world's largest oil services
company. The contract is for hybrid optoelectronic subsystems that will be
incorporated into sea-floor scanning devices. These systems began to be shipped
during fiscal 1999 and will be finished shipping during fiscal 2000. Due to the
worldwide decline in the oil exploration business, the Company and the customer
have subsequently agreed to reduce total shipments relating to the order, to
approximately $7.0 million.

   Security and Inspection Products. Since entering the security and inspection
products market in 1993, the Company has shipped approximately 3,500 units to
approximately 50 countries. The following is a list of certain customers and/or
installations that have purchased the Company's security and inspection
products since January 1993:

   Because the market for most security and inspection products developed in
response to civilian airline highjackings, historically a large portion of the
Company's security and inspection products were sold and continue to be sold
for use at airports. Recently, however, the Company's security and inspection
products have been used for security purposes at locations in addition to
airports, such as courthouses, government buildings, mail rooms, schools,
prisons and at unique locations such as Buckingham Palace in London, England.
In addition, the Company's security and inspection products are increasingly
being used for non-security purposes, such as for cargo inspection to detect
narcotics and contraband, prevention of pilferage at semiconductor
manufacturing facilities, quality assurance for agricultural products, and the
detection of gold and currency.

   In May 1998, Rapiscan U.S.A. and the FAA entered into a Cooperative Research
and Development Agreement (the "CRDA"). Under the CRDA, the Company and the
FAA's Technical Center will jointly attempt to develop, over a three-year
period, effective enhanced automated baggage screening systems at airports,
using Rapiscan's proprietary scanner technology and image processing ability.
Rapiscan U.S.A. will retain title in all inventions made solely by employees of
Rapiscan U.S.A. and the U.S. Government will have the option to retain title to
all inventions made solely by the employees of the U.S. Government or jointly
by employees of Rapiscan U.S.A. and the U.S. Government. If the U.S. Government
retains title to any inventions under the CRDA, the U.S. Government will grant
Rapiscan U.S.A. an exclusive license for any invention for use in automated
detection of explosives in baggage, and a non-exclusive license for all other
inventions developed under the CRDA, in exchange for a royalty based on gross
revenues from the licensed invention. If Rapiscan U.S.A. retains title to any
inventions under the CRDA, Rapiscan U.S.A. will grant the U.S. Government a
non-exclusive license with respect to such inventions. The party retaining
title to inventions developed under the CRDA has the option to file a patent
application with respect thereto. Rapiscan U.S.A. has the option to own the
copyright in all software, documentation and other works created in whole or in
part by employees of Rapiscan U.S.A. under the CRDA.

   During fiscal 1999, the Company entered into a number of significant
agreements for the development and sale of the Company's security and
inspection products. Some of the principal agreements are the following.

   In November 1996, the Company entered into a $14 million contract with a
foreign customer to deliver 16 large cargo scanners. Eight of these cargo
scanners were shipped during fiscal 1998 and the balance were shipped during
fiscal 1999. Some installations are to be completed and spare parts are
expected to ship in the future.

   In September 1998, the Company entered into an agreement with the Federal
Aviation Administration for advanced contraband detection systems with Threat
Image Projection ("TIP") features. The systems began to be shipped to Category
X airports (designated due to their high security priority) in the United
States during fiscal 1999 and the remainder will be shipped during fiscal 2000.
In addition, the FAA ordered Rapiscan training computers to assist in the
instruction of advanced detection technologies to security personnel.

   In January 1999, the Company entered into an agreement with the People's
Republic of China to upgrade and provide technical support for the Vehicle
Cargo X-ray System ("VCXS") operated by the Chinese customs authority at
Shenzhen, near Hong Kong. The VCXS system allows a fast, detailed inspection of
fully loaded trucks, and 20-foot and 40-foot containers in lieu of a full
manual search.

   In March 1999, the Company was awarded a contract by BAA plc, the operator
of 11 airports around the world, including London's Heathrow Airport, the
busiest international airport in the world. Rapiscan U.K. will supply, install
and maintain approximately 100 x-ray systems used in screening cabin baggage
for explosives, weapons and other contraband. These systems feature advanced
detection software, including TIP. The agreement also provides for Rapiscan
U.K. to provide maintenance and support services on the installed systems for
five years.

Marketing, Sales and Service

   The Company markets and sells its optoelectronic and silicon pressure-sensor
devices and subsystems, and medical imaging systems, worldwide through both a
direct sales and marketing staff of 30 employees and indirectly through a
network of approximately 47 independent sales representatives and distributors.
Most of the in-house sales staff is based in the United States while most of
the independent sales representatives and distributors are located abroad.
Since the acquisition of AME in March 1997, the Company's marketing efforts in
Europe have been conducted through AME's sales and marketing staff and through
a network of approximately eight independent sales representatives. The Company
markets and sells its security and inspection products worldwide through a
direct sales and marketing staff of approximately 34 employees located in the
United States, Finland, Canada, the United Kingdom, Dubai, and Malaysia and
through a network of approximately 133 independent sales representatives.

                                       10
<PAGE>

   The Company's optoelectronic and silicon pressure-sensor products and
medical imaging systems sales staff, located in the United States, Denmark and
Norway, is supported by an applications engineering group whose members are
available to provide technical support. This support includes designing
applications, providing custom tooling and process integration, defining
solutions for customers and developing products that meet customer defined
specifications. The security and inspection and medical imaging products sales
staff is supported by a service organization of approximately 32 persons,
located primarily in the United States, the United Kingdom, Finland and
Malaysia. The Company also supports these sales and customer relations efforts
by providing operator training, computerized training and testing equipment,
in-country service, software upgrades, service training for customer
technicians and a newsletter on security issues.

   The Company considers its maintenance service operations to be an important
element of its business. After the expiration of the standard product warranty
period, the Company is often engaged by its customers to provide maintenance
services for its security and inspection products through annual maintenance
contracts. The Company believes that its international maintenance service
capabilities allow it to be competitive in selling its security and inspection
products. Furthermore, the Company believes that as its installed base of
security and inspection products increases, revenues generated from such annual
maintenance service contracts and from the sale of replacement parts will
increase. In fiscal 1998 and 1999, maintenance service revenues and replacement
part sales collectively represented 3.5%, and 3.6% respectively, of the
Company's revenues.

Research and Development

   The Company's components and optoelectronic subsystems are designed and
engineered at the Company's facilities in either Hawthorne and Fremont,
California, or Horten, Norway. The subsystems that the Company manufactures are
engineered by the Company to solve specific application needs of its OEM
customers. The Company's customers typically request that the Company design
custom optoelectronic solutions for their specific needs when standard
components or subsystems are not available from other manufacturers of
optoelectronic and silicon pressure-sensor devices. After an end-product has
been conceptualized by the OEM, the Company normally will involve its engineers
to design the application, establish the mechanical specifications for the
application, create the appropriate subsystem architecture for the application,
and design the development, production and assembly process for the manufacture
of the ultimate subsystem. However, because the Company has the engineering,
tooling and manufacturing capabilities to design and manufacture entire
subsystems, and not just a specific component, the Company typically also
designs, manufactures and assembles the entire subsystem for the customer.
Because the Company's engineers are able to provide additional value and
services to its customers through the entire production process from concept to
completion, the Company considers its engineering personnel to be an important
extension of its core sales and marketing effort.

   In addition to close collaboration with the Company's customers in the
design and development of optoelectronics-based products, the Company maintains
an active program for the development and introduction of new products and
enhancements and improvements to its existing products, including the
implementation of new applications of its technology. The Company seeks to
further develop its research and development program and considers such a
program to be an important element of its business and operations. As of June
30, 1999, in addition to the engineers that the Company employed in
manufacturing, process design and applications development, the Company engaged
approximately 64 full-time engineers and technicians in research and
development. During fiscal 1998 and 1999, the Company's research and
development expenses were approximately $3.8 million and $5.7 million,
respectively. A significant portion of the increase in research and development
in fiscal 1999 is the result of acquisitions during that year. In order to
fulfill its strategy of increasing its security and inspection product lines
and of enhancing the capabilities of its existing products, the Company intends
to continue to increase its research and development efforts in the future.

   The Company's security screening products are designed at Rapiscan U.S.A.'s
facilities in Hawthorne, California and Rapiscan U.K.'s facilities in Crawley,
England and Espoo, Finland. These products include mechanical, electrical,
electronic, digital electronic and software subsystems, which are all designed
by the

                                       11
<PAGE>

Company. In addition to product design, the Company provides system integration
services to integrate its products into turnkey systems at the customer site.
The Company supports cooperative research projects with government agencies
and, on occasion, provides contract research for its customers and government
agencies.

Manufacturing and Materials Management

   The Company currently has manufacturing facilities in the United Kingdom,
Malaysia, Finland, Canada, Norway and Denmark, in addition to its manufacturing
facilities in Hawthorne and Fremont, California and Ocean Springs, Mississippi.
The Company recently announced that its facilities in Denmark will be closed.
The Company's principal manufacturing facility is in Hawthorne, California.
However, most of the Company's high volume, labor intensive manufacturing and
assembly is generally performed at its facilities in Malaysia. Since most of
the Company's customers currently are located in Europe and the United States,
the Company's ability to assemble its products in these markets and provide
follow-on service from offices located in these regions is an important
component of the Company's global strategy.

   The Company seeks to focus its subsystem manufacturing resources on its core
competencies that enable it to provide value-added enhancements and distinctive
value. The Company believes that its manufacturing organization has expertise
in optoelectronic, electrical and mechanical manufacturing and assembly of
products for commercial applications and for high reliability applications.
High reliability devices and subsystems are those which are designed,
manufactured, screened and qualified to function under exceptionally severe
levels of environmental stress. The manufacturing techniques include silicon
wafer processing and fabrication, manufacture and assembly of photodiodes,
surface mounting (SMT) and manual thru-hole assembly, thick-film ceramic
processing, wire bonding, molding, assembly of components, testing, and
packaging. The Company also has the ability to manufacture plastic parts and
certain other parts that are either not available from third party suppliers or
that can be more efficiently or cost-effectively manufactured in-house. The
Company outsources certain manufacturing operations including its sheet metal
fabrication. The manufacturing process for components and subsystems consists
of manual tasks performed by skilled and semi-skilled workers as well as
automated tasks. The number of subsystems that the Company manufacturers
depends on the customers' needs and may range from a few subsystems (such as an
optoelectronic sun sensor for use in a satellite) to many thousands (sensors
used in laser printers and bar code readers).

   The principal raw materials and subcomponents used in producing the
Company's optoelectronic devices and subsystems consist of silicon wafers,
ceramics, electronic subcomponents, light emitting diodes, phototransistors,
printed circuit boards, headers and caps, housings, cables, filters and
packaging materials. For cost, quality control and efficiency reasons, the
Company generally purchases raw materials and subcomponents only from single
vendors with whom the Company has ongoing relationships. The Company does,
however, qualify second sources for most of its raw materials and
subcomponents, or has identified alternate sources of supply. The Company
purchases the materials pursuant to purchase orders placed from time to time in
the ordinary course of business. The silicon-based optoelectronic devices
manufactured by the Company are critical components in most of its subsystems.
Since 1987, the Company has purchased substantially all of the silicon wafers
it uses to manufacture its optoelectronic devices from Wacker Siltronic Corp.
Although to date the Company has not experienced any significant shortages or
material delays in obtaining any of its raw materials or subcomponents, there
can be no assurance that the Company will not face such shortages or delays in
one or more of these materials in the future.

   Substantially all of the optoelectronic devices, subsystems, circuit boards
and x-ray generators used in the Company's inspection and detection systems are
manufactured in-house. The metal shells of the x-ray inspection systems, and
certain standard mechanical parts are purchased from various third-party
unaffiliated providers.

Patents and Trademarks

   In July 1999, as part of the settlement of an arbitration, the Company
entered into a nonexclusive patent license agreement with EG&G, Inc. ("EG&G")
for U.S. Patent No. 4,366,382, which expires in 2000. Under the fully paid up
license, for which the Company has paid $450,000, the Company is permitted to
make, use and sell or otherwise dispose of security and inspection products
that use an x-ray line scan system for baggage inspection purposes covered by
EG&G's patent. The Company may be required to make additional payments of up to
$350,000, based on certain potential future orders and shipments.

   In December 1998, as part of the settlement of certain litigation, the
Company and Lunar Corporation ("Lunar") made payments to each other which
resulted in a net payment to the Company of $400,000. As part of the
settlement, the parties entered into a license agreement pursuant to which the
Company, Rapiscan and UDT were granted a fully paid up worldwide, nonexclusive
license under U.S. Patent Nos. 4,626,688 (the "688 patent") and 5,138,167 (the
"167 patent") in the non-medical field. The Company paid Lunar $1.5 million for
this fully paid up license.

   Prior to the Company's acquisition of Osteometer in September 1998,
Osteometer had also been involved in litigation with Lunar regarding the 688
and 167 patents. In December 1998, the parties to this litigation entered into
a settlement agreement. As a part of the settlement, the parties entered into a
license agreement pursuant to which Osteometer was granted a worldwide,
nonexclusive license under the 688 and 167 patents for certain bone
densitometers. Osteometer made an initial royalty payment of $250,000 with
respect to products manufactured prior to the entering into of this license
agreement and the Company will make royalty payments on future sales of the
licensed products. The license expires in December 2003 or the last to expire
of the licensed patents, whichever is later.

   Rapiscan owns U.S. Patent No. 5,181,234 covering personnel screening systems
and manufactures the Secure 1000 in accordance to the patent. This patent was
issued in 1993 and expires in 2010. Rapiscan utilizes the trademarks
Rapiscan(R) and Secure(TM).

   SMI owns U.S. Patent No. 5,812,047, which applies in connection with the
manufacture of silicon pressure-sensor devices. The patent expires in 2017. SMI
has other patent applications pending for various applications; it is unknown
at this time if these patents will be issued.

   Metorex Security's "Metor" trademark is registered in 25 countries,
including the United States, the European Union countries and Japan. Metorex
Security has also registered the trademark "Metorscan" in the United States and
the European Union countries. Metorex Security utilizes four patents registered
in the United States (U.S. Patent Nos. 4605898, 5121105, 5047718, 4894619) and
other countries, including the European Union countries. These patents were
issued between 1986 and 1995, with expirations between 2002 and 2008. The
patents cover various improvements in metal detection systems.

   The Company believes that the above patents and trademarks are important to
the Company's business. The loss of some of these patents or trademarks might
have a negative impact; however, the Company operates in a competitive
environment with a known customer base and relies mainly on providing value for
money with quality products and services to ensure continuing business.

Environmental Regulations

   The Company is subject to various federal, state and local environmental
laws, ordinances and regulations relating to the use, storage, handling, and
disposal of certain hazardous substances and wastes used or generated in the
manufacturing and assembly of the Company's products. Under such laws, the
Company may become liable for the costs of removal or remediation of certain
hazardous substances that have been or are being released on or in its
facilities or that have been or are being disposed of off site as wastes. Such
laws may impose liability without regard to whether the Company knew of, or
caused, the release of such hazardous substances. In the past, the Company has
conducted a Phase I environmental assessment report for each of the

                                       13
<PAGE>

properties in the United States at which it currently manufactures products.
The purpose of each such report was to identify, as of the date of that report,
potential sources of contamination of the property. In certain cases, the
Company has received a Phase II environmental assessment report consisting of
further soil testing and other investigations deemed appropriate by an
independent environmental consultant. The Company believes that it is currently
in compliance with all material environmental regulations in connection with
its manufacturing operations, and that it has obtained all environmental
permits necessary to conduct its business. The amount of hazardous substances
and wastes produced and generated by the Company may increase in the future
depending on changes in the Company's operations. Any failure by the Company to
comply with present or future regulations could subject the Company to the
imposition of substantial fines, suspension of production, alteration of
manufacturing process or cessation of operations, any of which could have a
material adverse effect on the Company's business, financial condition and
results of operations.

Competition

   The markets in which the Company operates are highly competitive and
characterized by evolving customer needs and rapid technological change. The
Company competes with a number of other manufacturers, many of which have
significantly greater financial, technical and marketing resources than the
Company. In addition, these competitors may have the ability to respond more
quickly to new or emerging technologies, adapt more quickly to changes in
customer requirements, have stronger customer relationships, have greater name
recognition, and devote greater resources to the development, promotion and
sale of their products than does the Company. There can be no assurance that
the Company will be able to compete successfully against any current or future
competitors in either the optoelectronic and silicon pressure-sensor devices
and subsystems and medical imaging systems market or the security and
inspection market or that future competitive pressures will not materially and
adversely affect its business, financial conditions and results of operations.

   In the optoelectronic and silicon pressure-sensors devices and subsystems
market, competition for optoelectronic devices and subsystems is based
primarily on such factors as expertise in the design and development of
optoelectronic devices, product quality, timeliness of delivery, price,
customer technical support, and on the ability to provide fully integrated
services from application development and design through volume subsystem
production. The Company believes that its major competitors in the
optoelectronic device and subsystem market are EG&G Electro-Optics, a division
of EG&G, Inc., Hamamatsu Corporation, and Honeywell Optoelectronics, a division
of Honeywell, Inc. Because the Company specializes in custom subsystems
requiring a high degree of engineering expertise, the Company believes that it
generally does not compete to any significant degree with any other large
United States, European or Asian manufacturers of standard optoelectronic
components. Competition for the Company's medical imaging products comes
principally from Lunar Corporation, Hologic, Inc. and Norland Medical Systems,
Inc. In the case of silicon pressure-sensors and microstructures, the Company
bases much of its current competitive position on pressure sensor performance,
particularly at low pressures, and process and manufacturing controls,
particularly in the automotive areas. Customer support and design expertise are
also very important. The Company believes that its primary silicon pressure-
sensor competitors include IC Sensors Division of EG&G, Inc., Novasensor
Division of Lucas Controls, Sensym ICT, and Motorola Semiconductor group.

   In the security and inspection market, competition is based primarily on
such factors as product performance, functionality and quality, the over-all
cost effectiveness of the system, prior customer relationships, technological
capabilities of the products, price, local market presence, and breadth of
sales and service organization. The Company believes that its principal
competitors in the market for security and inspection products are EG&G
Astrophysics, a division of EG&G, Inc., Heimann Systems GmbH, InVision
Technologies, Inc., Vivid Technologies, American Science and Engineering, Inc.,
Barringer Technologies Inc., Control Screening L.L.C., and Thermedics
Detection, Inc. Competition could result in price reductions, reduced margins,
and loss of market share by the Company. The Company believes that the
principal competitor for its products using x-ray backscatter detection
technology is American Science & Engineering, Inc. In the airline

                                       14
<PAGE>

and airport security and inspection market, particularly in the upgrade and
replacement market, the Company also competes for potential customers based on
existing relationships between its competitors and the customers. Certain of
the Company's competitors have been manufacturing inspection systems since the
1980s and have established strong relationships with airlines and airport
authorities. The Company believes that the image quality and resolution of
certain of its security and inspection products is superior to the image
quality offered by most of its competitors' x-ray based inspection products.
Although the Company also has established relationships with a number of
airport and airline customers, no assurance can be given that the Company will
be able to successfully compete in the future with existing competitors or with
new entrants.

Backlog

   The Company measures its backlog as orders for which purchase orders or
contracts have been signed, but which have not yet been shipped and for which
revenues have not yet been recognized. The Company typically ships its
optoelectronic and silicon pressure-sensor devices and subsystems, and medical
imaging systems, as well as its security and inspection products within one to
three months after receiving an order. However, such shipments may be delayed
for a variety of reasons including any special design or engineering
requirements of the customer. In addition, large orders (more than ten
machines) of security and inspection products typically require more lead time.

   Large cargo scanning machines require six to twelve months lead time. The
only significant shipping delays which the Company has experienced are with
large cargo scanners. Such delays can occur for any of the following reasons:
(i) additional time necessary to conduct large cargo inspections at the factory
before shipment; (ii) the customer's needs to engage in timely special site
preparation to accommodate such a scanner, and as to which the Company has no
control or responsibility; and (iii) additional fine tuning of such scanners
once they are installed. The Company has experienced delays in shipping large
cargo scanners to one customer because of logistical delays by that customer;
however, all such delayed shipments of scanners to that customer were shipped
during fiscal 1999.

   At June 30, 1999, the Company's backlog products totaled approximately $44.1
million, compared to approximately $46.9 million at June 30, 1998. Most of the
Company's backlog as of June 30, 1999 is expected to be shipped during the
fiscal year ending June 30, 2000. Any failure of the Company to meet an agreed
upon schedule could lead to the cancellation of the related order. Variations
in the size of the order, the product mix, and delivery requirements of the
customer order may result in substantial fluctuations in backlog from period to
period. Backlog as of any particular date should not be relied upon as
indicative of the Company's revenues for any future period and cannot be
considered a meaningful indicator of the Company's performance on an annual or
quarterly basis.

Employees

   As of June 30, 1999, the Company employed approximately 922 people, of whom
687 were employed in manufacturing, 64 were employed in research and
development, 75 were employed in finance and administration, 64 were employed
in sales and marketing, and 32 were employed in its service organization. Of
the total employees, approximately 433 were employed in the United States, 26
in Canada, 191 were employed in Europe, 271 were employed in Asia, and one was
employed in the Middle East. Thirty-two employees at AME and nine Metorex
Security employees in Finland are members of a union and have collective
bargaining rights. Other than the employees of AME and nine Metorex Security
employees in Finland, none of the Company's other employees is unionized. There
has never been a work stoppage or strike at the Company, and management
believes that its relations with its employees are good.

   The Company's lease of facilities in Johor Bahru, Malaysia covering
approximately 13,500 square feet will expire in November 1999 and it is
anticipated that this lease will be extended on terms yet to be negotiated. The
Company's lease of facilities in Johor Bahru, Malaysia covering approximately
21,000 square feet will expire in April 2000 and it is anticipated that this
lease will be extended on terms yet to be negotiated.

   The Company's lease of facilities in Singapore will expire during fiscal
2000. The Company expects to renew this lease but has not yet begun
negotiations with respect thereto.

   The Company believes that its facilities are in good condition and are
adequate to support its operations for the foreseeable future. The Company
currently anticipates that it will be able to renew the leases that are
scheduled to expire in the next few years on terms that are substantially the
same as those currently in effect. However, even if the Company were not able
to renew one or more of the leases, the Company believes that suitable
substitute space is available to relocate any of the facilities. Accordingly,
the Company does not believe that its failure to renew any of the leases that
are scheduled to expire in the next few years will have a material adverse
effect on the Company's operations.

ITEM 3. Legal Proceedings

   In October 1994, UDT Sensors entered into a Consent Judgment and a Criminal
Plea and Sentencing Agreement (collectively, the "Consent Agreements") with the
United States of America. The charges contained in the Consent Agreements
relate to high-reliability optoelectronic subsystems that UDT Sensors
manufactured for use in military aircraft, attack helicopters and submarines.
In the Consent Agreements, UDT Sensors agreed that it had not tested 100% of
these products as required by the applicable military specifications. Under the
terms of the Consent Agreements, UDT Sensors has paid a total of $1.5 million,
plus interest, in five annual installments ending on March 31, 1999. UDT
Sensors was placed on probation for the

                                       16
<PAGE>

five-year period ending March 31, 2000 with respect to sales of optoelectronic
subsystems for use by the U.S. Department of Defense. Probation does not,
however, prohibit UDT Sensors from selling optoelectronic products to the
United States, and UDT Sensors has, since the date of the Consent Agreements,
continued to manufacture and sell the same optoelectronic products for use in
military aircraft, attack helicopters and submarines. In addition, in order to
ensure that UDT Sensors complies with all Federal procurement laws, UDT Sensors
agreed to implement programs and practices to establish and monitor complying
contracting procedures, and agreed to file periodic reports evidencing such
practices and programs.

   The Company is also involved in routine litigation from time to time in the
course of conducting its business.

public offering in 1997 and anticipates that it will retain any available funds
for use in the operation of its business, and does not currently intend to pay
any cash dividends in the foreseeable future. Future cash dividends, if any,
will be determined by the Board of Directors. The payment of cash dividends by
the Company is restricted by certain of the Company's current bank credit
facilities, and future borrowing may contain similar restrictions.

Overview

   The Company is a vertically integrated worldwide provider of devices,
subsystems and end-products based on optoelectronic and silicon pressure-sensor
micro-structure technology. The Company designs and manufactures optoelectronic
and silicon pressure-sensor devices and value-added subsystems for OEMs for use
in a broad range of applications, including security, medical diagnostics,
telecommunications, gaming, office automation, aerospace, computer peripherals
and industrial automation. In addition, the Company utilizes its optoelectronic
technology and design capabilities to manufacture security and inspection
products that it markets worldwide to end users under the "Rapiscan," "Secure"
and "Metor" brand names. These products are used to inspect people, baggage,
cargo and other objects for weapons, explosives, drugs and other contraband.
The Company has also, through the acquisition of Osteometer, expanded into the
manufacture and sale of bone densitometers, which are used to provide bone loss
measurements in the diagnosis of osteoporosis. In fiscal 1999, revenues from
the sale of optoelectronic and silicon pressure-sensor devices and subsystems
and medical imaging systems amounted to $55.5 million, or approximately 54.5%
of the Company's revenues, while revenues from sales of security and inspection
products amounted to $46.3 million, or approximately 45.5% of the Company's
revenues.

   The Company was organized in May 1987. The Company's initial products were
optoelectronic devices and subsystems sold to customers for use in the
manufacture of x-ray scanners for carry-on airline baggage. In December 1987,
the Company formed Opto Sensors (Singapore) Pte Ltd. ("OSI Singapore") to
manufacture optoelectronic devices and subsystems. In April 1990, the Company
acquired UDT Sensors' subsystem business. In February 1993, the Company
acquired the security and inspection operations of Rapiscan U.K. and, through
Rapiscan U.S.A., commenced its operations as a provider of security and
inspection products in the United States. In April 1993, the Company acquired
Ferson Optics, a U.S. manufacturer of passive optic components. In July 1994,
the Company established OSI Malaysia to manufacture optoelectronic subsystems
as well as security and inspection products. In March 1997, the Company
acquired AME for the purpose of broadening its optoelectronic subsystem
business in Europe. The Company currently owns all of the outstanding shares of
each of these companies. In January 1998, the Company acquired the "Secure"
product line from ThermoSpectra for the purpose of expanding into the area of
inspection of people. In fiscal 1999, the Company acquired Osteometer for the
purpose of expanding further into the field of optoelectronic medical devices
used for medical diagnostic purposes. Due to the global decline in the bone
densitometer market, the Company recently announced the closure of Osteometer's
manufacturing facilities in Denmark. Currently, the Company intends to relocate
certain of these operations to the United States over the next several months.
The Company expects to incur additional expenses in connection with the
discontinuation of those operations and

                                       21
<PAGE>

their intended relocation to the United States, which will be recorded in
future periods. Based on its assessment to date, the Company currently
estimates these expenses to be in the range of $2.0 million to $2.7 million. As
the Company continues to proceed with the closure and intended relocation of
these manufacturing facilities, it will be able to more accurately estimate the
range of these costs, which may change from the current estimate.

   In January 1994, the Company entered into a joint venture agreement with
Electronics Corporation of India, Limited ("ECIL"), an unaffiliated Indian
corporation, pursuant to which the Company and ECIL formed ECIL Rapiscan. The
joint venture was established for the purpose of manufacturing security and
inspection products in India from kits sold to ECIL by the Company. The Company
currently owns a 36.0% interest in ECIL Rapiscan.

   In August 1998, the Company invested $315,000, including professional fees
associated with the acquisition, in Square One for an equity share of
approximately 16%. The Company's equity in the earnings of the investment,
since acquisition, has not been significant. Square One develops and
manufactures infrared-based patient monitoring medical subsystems.

   During fiscal 1999, the Company invested $1,002,000, including professional
fees associated with the acquisition, in TFT Medical for an equity share of
approximately 40%. At June 30, 1999, the Company's equity in the losses of the
investment was $187,000. TFT Medical develops new generation pulse oximeter
instruments and probes for use in the medical field.

   The Company engages in significant international operations. The Company
currently manufactures its optoelectronic and silicon pressure-sensor devices
and subsystems, and medical imaging systems, at its facilities in Hawthorne and
Fremont, California, Ocean Springs, Mississippi; Johor Bahru, Malaysia; Horten,
Norway; and Horsholm, Denmark. Its security and inspection products are
manufactured at its facilities in Crawley, England; Hawthorne, California;
Johor Bahru, Malaysia; and Espoo, Finland. As of June 30, 1999, the Company
marketed its products worldwide through approximately 64 sales and marketing
employees located in eight countries, and through approximately 180 independent
sales representatives. Revenues from shipments made outside of the United
States accounted for 42.2%, 49.4% and 48.5% of revenues for the fiscal years
1997, 1998 and 1999 respectively. Information regarding the Company's operating
income or loss and identifiable assets attributable to each of the Company's
geographic areas is set forth in Note 15 in the Company's Consolidated
Financial Statements.

   The effective income tax rate for the Company for fiscal 1997, 1998 and
excluding the non-recurring asset impairment charge, in-process research and
development and restructuring costs for fiscal 1999 was 25.3%, 25.0% and 16.5%,
respectively. Certain products manufactured in the United States and sold
overseas are sold through a Foreign Sales Corporation ("FSC") organized by the
Company in 1990. Export sales made through the FSC are subject to federal tax
advantages. Because of a number of factors, primarily variable and changing
international taxation policies, including those in Malaysia, and utilization
of previously unrealized net operating loss, the Company is not able to
estimate its effective tax rate during the next fiscal year.

   Certain competitive and industry trends include the following. Rapiscan
U.S.A. and its competitors in the security and inspection business have been
experiencing weakness in the domestic market, partly as a result of hesitation
by airlines to order security and inspection equipment pending a decision by
the FAA to buy 440 cabin-baggage scanners using current technology. The FAA has
leased, with an option to buy, ten such scanners from the Company. FAA trials
are continuing.

   The incorporation of SMI's silicon pressure-sensor products into the
Company's operations has taken longer than originally anticipated. As a result,
costs of operations for SMI's operations have been higher than expected and may
continue as such for at least the next few quarters. The Company has
established an internal task force to oversee the incorporation of SMI's
operations into those of the Company.

   The Company's subsystems optics business is conducted by Ferson Optics,
which manufactures passive components used in other products and systems
manufactured by outside parties and the Company. Because of

                                       22
<PAGE>

competitive market forces, primarily in Asia with significantly lower costs of
labor, sales of Ferson Optic's products to outside parties show little
opportunity of growth in the foreseeable future. The Company is actively
monitoring this situation and will consider implementing additional cost-saving
and cost-cutting measures, including use of subcontractors and consolidation of
manufacturing operations, in the future. Ferson Optics is a small portion of
the Company's business, contributing approximately $ 3.3 million, or
approximately 3.2% of total revenue in fiscal 1999.

   The Company recognizes revenues upon shipment. As the Company's product
offerings change to include sales of significantly larger systems, such as
cargo inspection products, the Company may adopt the percentage of completion
method of revenue recognition for certain products.

</TABLE>

Comparison of Fiscal Year Ended June 30, 1999 to Fiscal Year Ended June 30,
1998

   Revenues. Revenues consist of sales of optoelectronic and silicon pressure
sensor devices, subsystems and medical imaging systems as well as security and
inspection products. Revenues are recorded net of inter-company eliminations.
Revenues for the fiscal year ended June 30, 1999, increased by $7.8 million or
8.4% to $101.8 million from $93.9 million for the fiscal year ended June 30,
1998. Revenues for the sale of optoelectronics and silicon pressure sensor
devices, subsystems and medical imaging systems, net of intercompany
eliminations, increased by $5.4 million, or 10.7% to $55.5 million from $50.1
million for fiscal 1998. The increase was primarily due to an increase in sales
to the oil exploration industry and sales of medical imaging systems and
silicon pressure sensors through the acquisitions of Osteometer and SMI,
respectively. Due to the worldwide decline in the oil exploration business, the
Company expects declines in shipments to the oil exploration industry to
continue and has no plans to actively pursue this market after the completion
of its current contract. Revenues from the sale of security and inspection
products increased $2.5 million, or 5.7% to $46.3 million from $43.8 million
for fiscal 1998. The increase in revenues from the sale of security and
inspection products was primarily due to an increase in walk through metal
detection systems through the acquisition of Metorex Security, which was offset
in part by decrease in revenues due to weakness in the security and inspection
products market.

                                       23
<PAGE>

   Gross Profit. Cost of goods sold consist of material, labor and
manufacturing overhead. Gross profit increased by $3.1 million, or 11.5% to
$30.1 million from $27.0 million for fiscal 1998. As a percent of revenues,
gross profit increased to 29.5% in fiscal 1999 from 28.7% in fiscal 1998. The
increase in gross profit was due to increased sales, change in product mix and
increased efficiencies in manufacturing.

   Selling, General and Administrative. Selling, general and administrative
expenses consist primarily of compensation paid to sales, marketing, and
administrative personnel, professional service fees and marketing expenses. For
the year ended June 30, 1999, such expenses increased by $4.8 million, or 37.7%
to $17.5 million from $12.7 million in fiscal 1998. As a percentage of
revenues, selling, general and administrative expenses increased to 17.1% in
fiscal 1999 from 13.5% in fiscal 1998. The increase in expenses was due
primarily to the inclusion of selling, general and administrative expenses of
recent acquisitions in the Company's consolidated financial statements,
exchange rate fluctuation losses due to currency translation relating to the
relatively strong U.S. dollar compared to European currencies and an increase
in marketing expenses to penetrate new markets for the Company's existing
products and was offset in part by the proceeds from the settlement of certain
material litigation. For the year ended June 30, 1999, $4.5 million of selling,
general and administrative expenses of recent acquisitions were included in the
Company's consolidated financial statements. The exchange rate losses for
fiscal 1999 were $743,000 compared to $39,000 for fiscal 1998.

   Research and Development. Research and development expenses include research
related to new product development and product enhancement expenditures. For
the year ended June 30, 1999, such expenses increased by $1.9 million, or 50.7%
to $5.7 million from $3.8 million in fiscal 1998. As a percentage of revenues,
research and development expenses increases to 5.6% in fiscal 1999 from 4.0% in
fiscal 1998. The increase in expenses was primarily due to the increase in
personnel cost resulting from the recent acquisitions. For the year ended June
30, 1999, $1.8 million of research and development expenses incurred by the
acquired companies were included in the Company's consolidated financial
statements.

   Goodwill Amortization. Amortization of goodwill increased to $595,000 in
fiscal 1999 from $106,000 in fiscal 1998. The increase in amortization expense
was primarily due to amortization of goodwill associated with the acquisition
of Osteometer, Metorex Security and SMI. In the prior years, goodwill
amortization was included as a component of selling, general and administrative
expenses.

   Asset Impairment Charge. The asset impairment charge relates to the closure
of the manufacturing facilities of Osteometer in Denmark. For the year ended
June 30, 1999, the asset impairment charge was $5.2 million, which includes the
write off of $3.7 million of goodwill and $1.5 million of other assets. Some of
these operations may be relocated to the United States over the next several
months. The Company expects to incur additional expenses in connection with the
discontinuation of those operations and their intended relocation to the United
States, which will be recorded in future periods.

   In Process Research and Development. The Company used a total of $15.3
million for the acquisitions of Osteometer, Metorex Security and SMI, including
professional fees associated with these acquisitions. Out of the total of $15.3
million, the company incurred an aggregate of $2.6 million in in-process
research and development charges in fiscal 1999, related to these acquisitions.
In September 1998, the Company acquired the assets, including the developmental
technology, and assumed the liabilities of Osteometer. The Company paid $7.9
million in cash, including professional fees associated with the acquisition.
In November 1998, the Company acquired the assets, including developmental
technology, of Metorex Security. The Company paid $4.7 million in cash,
including professional fees associated with the acquisition, and in July 1999,
the Company paid $4.4 million Finnish markka (approximately $759,000), in lieu
of contingent payments up to $1.5 million, based on future sales. Also in
November 1998, the Company acquired the assets, including the developmental
technology, of SMI. The Company paid $2.7 million in cash, including
professional fees associated with the acquisition, and may pay up to $3.9
million in additional contingent purchase payments based on future sales.

   Based on the valuations, the Company allocated the excess of the non-
contingent purchase price over the fair value of net tangible assets acquired
to goodwill and identified intangible assets. In performing this

                                       24
<PAGE>

allocation, the Company considered, among other factors, the attrition rate of
the active users of the technology at the date of acquisition and the research
and development projects in process at the date of acquisition. With regard to
the in-process research and development projects, the Company considered, among
other factors, the stage of development of each project at the time of
acquisition, the importance of each project to the overall development plan,
and the projected incremental cash flows from the projects when completed and
any associated risks. Associated risks include the inherent difficulties and
uncertainties in completing each project and thereby achieving technological
feasibility and risks related to the impact of potential changes in future
target markets. As of June 30,1999, with the exception of Osteometer, the above
mentioned research and development projects were progressing as planned.

   Restructuring Costs. During fiscal 1999, the Company adopted a restructuring
plan to consolidate certain subsidiaries and, in connection therewith, the
Company recorded a non-recurring expense of $458,000. These costs were
associated primarily with the termination of certain employees, in the amount
of $395,000, and consolidation of certain subsidiaries, in the amount of
$63,000. All of the restructuring costs were incurred and recorded before March
31, 1999.

   Income (loss) from operations. For the year ended June 30, 1999, loss from
operations was $1.9 million compared to income of $10.4 million in fiscal 1998.
Excluding, the non-recurring asset impairment charge, in process research and
development and restructuring costs of $8.2 million, income from operations for
the year ended June 30, 1999 decreased by $4.1 million or 39.4%, to $6.3
million from $10.4 million in fiscal 1998. Income from operations decreased due
to increased selling, general and administrative expenses, increased research
and development expenses and increased goodwill amortization and was partially
offset by increased gross profit.

   Interest expense (income). For the year ended June 30, 1999, the Company
earned net interest income of $102,000 compared to net interest income of
$600,000 for fiscal 1998. The reduction in net interest income was due to
increased borrowing on the Company's lines of credit and a reduction in short
term investments used for working capital and acquisitions.

   Provision (benefit) for income taxes. For the year ended June 30, 1999, the
Company had an income tax benefit of $2.6 million compared to provision for
income taxes of $2.7 million for fiscal 1998. Excluding, the non-recurring
asset impairment charge, in process research and development and restructuring
costs, provision for income taxes for the year ended June 30, 1999, was $1.1
million, compared to $2.8 million for fiscal 1998 and as a percentage of income
before provision for income taxes, provision for income taxes was 16.5% for the
year ended June 30, 1999 compared to 25.0% for fiscal 1998. The reduction in
the Company's effective tax rate was primarily due to a mix in income from U.S.
and foreign operations, utilization of previously unrealized foreign net
operating losses and a one year tax holiday in Malaysia for fiscal year ended
June 30, 1999.

   Net Income. For the reasons outlined above, including the non-recurring
asset impairment charge, in process research and development and restructuring
costs, for the year ended June 30, 1999, the Company had a net income of
$741,000, compared to $8.2 million for fiscal 1998. Excluding, the non-
recurring asset impairment charge, in process research and development and
restructuring costs of $8.2 million ($4.7 million of net of taxes), net income
for the year ended June 30, 1999 decreased 35.2% to $5.3 million, compared to
$8.2 million for fiscal 1998.

Comparison of Fiscal Year Ended June 30, 1998 to Fiscal Year Ended June 30,
1997

   Revenues. Revenues consist of sales of optoelectronics devices and
subsystems as well as security and inspection products. Revenues are recorded
net of inter-company eliminations. Revenues for the fiscal year ended June 30,
1998 increased by $16.3 million, or 21.0% to $93.9 million from $77.6 million
for the fiscal year ended June 30, 1997. Revenues for the sale of
optoelectronics devices and subsystems, net of intercompany eliminations,
increased by $7.2 million, or 16.9% to $50.1 million from $42.9 million for
fiscal 1997. The increase was the result of increase in sales to medical
diagnostic and gaming industry and introduction of products that are sold for
use in the oil exploration field. Revenues from the sale of security and

                                       25
<PAGE>

inspection products increased by $9.0 million, or 26.0% to $43.8 million from
$34.7 million for fiscal 1997. The increase was due to an increase in sales of
the Company's Rapiscan Series 500 systems and large cargo inspection machines,
and continuing penetration in the security and inspection products market.

   Gross Profit. Cost of goods sold consists of material, labor and
manufacturing overhead. Gross profit increased by $5.5 million, or 25.7% to
$27.0 million from $21.5 million for fiscal 1997. As a percentage of revenues,
gross profit increased to 28.7% in fiscal 1998 from 27.6% in fiscal 1997. The
increase in gross profit was due to increased sales and increased efficiencies
in manufacturing.

   Selling, General and Administrative. Selling general and administrative
expenses consist primarily of compensation paid to sales, marketing, and
administrative personnel, professional service fees, and marketing expenses.
For the year ended June 30, 1998 such expenses increased by $1.4 million, or
12.5%, to $12.7 million from $11.3 million in fiscal 1997. This increase was
due primarily to an increase in payroll expenses and marketing expenses to
support revenue growth as well as an increase in legal expenses related
primarily to ongoing litigation matters. As a percentage of revenues, selling,
general and administrative expenses decreased to 13.5% in fiscal 1998 from
14.5% in fiscal 1997.

   Research and Development. Research and development expenses include research
related to new product development and product enhancement expenditures. For
the year ended June 30, 1998, such expenses increased by $1.3 million, or
51.4%, to $3.8 million from $2.5 million in fiscal 1997. As a percentage of
revenues, research and development expenses increased to 4.0% in fiscal 1998
from 3.2% in fiscal 1997. The increase was due primarily to acceleration of
certain research and development projects, continued enhancement of Rapiscan x-
ray systems, and increased efforts to develop product for cargo scanning and
optoelectronic devices and subsystems products.

   Goodwill Amortization. Amortization of goodwill increased to $106,000 in
fiscal 1998 from $39,000 in fiscal 1997. The increase in goodwill was due to
the whole year's amortization in fiscal 1998 compared to a partial year's
amortization in fiscal 1997, as related to the acquisitions of minority
interests in Rapiscan and Ferson Optics, and the acquisition of AME.

   Income from Operations. Income from operations for the year ended June 30,
1998 increased by $3.6 million, or 53.2%, to $10.4 million from $6.8 million in
fiscal 1997. Excluding the non-recurring, non-cash incentive compensation
expense of $856,000 incurred in connection with the acceleration of the vesting
period of stock options granted to certain employees and officers during the
year ended June 30, 1997, income from operations increased by $2.8 million or
36.0%, from $7.6 million last year. As a percentage of revenues, income from
operations increased to 11.1% from 8.7% last year and excluding the non-cash
compensation expense referenced above, it would have increased to 11.1% from
9.8%.

   Interest Expense. For the year ended June 30, 1998, the Company earned net
interest income of $600,000 compared to net interest expense of $1.2 million in
fiscal 1997. The interest income was due to proceeds from the initial public
offering of the Company's common stock, in October 1997. A portion of the
proceeds was used to repay a majority of the Company's debt and the remaining
proceeds are invested in short-term investments.

   Provision for Income Taxes. Provision for income taxes for fiscal 1998
increased by $1.3 million, or 94.4% to $2.8 million, from $1.4 million for
fiscal 1997. As a percentage of income before provision for income taxes,
provision for income taxes decreased to 25.0% from 25.3% for fiscal 1997.

   Net Income. For the reasons outlined above, net income for the year ended
June 30, 1998 increased by $4.1 million, or 97.5%, to $8.2 million from $4.2
million in fiscal 1997. The non-cash compensation charge described above,
decreased net income by $514,000 in fiscal 1997.

Liquidity and Capital Resources

   The Company has financed its operations primarily through cash provided by
operations, through various term loans, discounting facilities, and credit
lines extended to its different subsidiaries worldwide and from its

                                       26
<PAGE>

public offering. As of June 30, 1999, the Company's principal source of
liquidity consisted of $7.2 million in cash and several credit agreements
described below.

   The Company's operations provided net cash of $80,000 during fiscal 1999,
compared to net cash used of $436,000 in fiscal 1998. The amount of net cash
provided by operations was offset in part primarily because of increase in
accounts receivable, other receivables, deferred income taxes, income taxes
receivable, reduction in accrued payroll and related expenses, income taxes
payable and advances from customers.

   The net cash used in investing activities was $23.4 million and $8.0 million
for fiscal 1999 and 1998, respectively. In fiscal 1999, net cash used in
investing activities reflects primarily cash used in business acquisitions and
professional fees associated with these acquisitions of $16.0 million, cash
used in equity investments, purchase of marketable securities and the purchase
of property and equipment, and was partially offset by cash provided by sale of
property and equipment. In fiscal 1998, the net cash used in investing
activities was primarily the purchase of property and equipment. The Company
expects to purchase property and equipment in fiscal 2000 as required. The
Company has no significant capital spending or purchase commitment other than
in normal course of business and commitments under leases.

   Net cash provided by financing activities was $7.5 million for fiscal 1999
compared to net cash provided by financing activities of $30.6 million for
fiscal 1998. In fiscal 1999, net cash provided by financing activities resulted
primarily from net proceeds from bank lines of credit and was partially offset
by payment of long term debt and purchase of treasury stock.

   In March 1999, the Company announced a stock repurchase program of up to
2,000,000 of its Common Stock. Through June 30, 1999, the Company repurchased
85,000 shares at an average price of $5.15 per share. Subsequent to the end of
the fiscal year ended June 30, 1999, the Company repurchased an additional
247,500 shares (through September 23, 1999) at an average price of $4.72 per
share. The stock repurchase program did not have a material effect on the
Company's liquidity and is not expected to have a material effect on liquidity
in subsequent quarters.

   The Company anticipates that current cash balances, anticipated cash flows
from operations and current borrowing arrangements will be sufficient to meet
its working capital, stock repurchase program and capital expenditure needs for
the foreseeable future.

   In January 1997, the Company and its U.S. subsidiaries entered into a credit
agreement with Sanwa Bank California. The agreement, as amended and restated in
September 1999, provides for a $10.0 million line of credit, which includes
revolving line, letter of credit, acceptance and foreign exchange facilities.
In addition, the Company has a $3.0 million equipment line of credit for
capital purchases, a $3.0 million term loan and a $15.0 million line of credit
for acquisitions with certain restrictions. Advances under the lines of credit
bear interest at a rate equal to a variable bank reference rate (7.75% at June
30, 1999) or, at the Company's option, at a fixed rate as quoted by the bank
upon request for specific advances. As of June 30, 1999, there were no amounts
outstanding under the line of credit or equipment line of credit and $8.5
million was outstanding under the acquisition line of credit. As of June 30,
1999, $66,000 was outstanding under letters of credit. The lines expire in
November 2000. Borrowings under the agreement are secured by liens on
substantially all of the assets of the Company's U.S. subsidiaries. The
agreement restricts the borrowers from incurring certain additional
indebtedness and from making capital expenditures greater than $5.0 million on
a consolidated basis (excluding assets acquired through acquisition) in any
fiscal year. In addition, the credit agreement contains certain covenants.
Among these, the Company is at all times required to maintain (on a
consolidated basis) a tangible net worth of at least $50.0 million; a ratio of
debt to tangible net worth of not more than 3.0 to 1; a ratio of cash, cash
equivalents and accounts receivable to current liabilities of not less than 0.8
to 1; and a debt coverage ratio of 2.0 to 1. The Company was in violation of a
covenant for the quarter ended June 30, 1999, due to the asset impairment
charge. The covenant was subsequently waived by the bank.

                                       27

   In November 1996, the Company and three of its U.S. subsidiaries entered
into an agreement with Wells Fargo HSBC Trade Bank, N.A. The agreement was
renewed in January 1998 and, in August 1998, was extended until November 1999.
As currently in effect, the agreement provides for revolving lines of credit up
to a maximum of $2.1 million to be used to pay obligations incurred in
connection with export orders. Of this total amount, there is a sublimit of
$1.0 million for the purchase of foreign currency and a sublimit of $1.9
million for letters of credit for a specific customer. The revolving credit
lines bear interest at the bank's prime rate (7.75% at June 30, 1999) plus 5.0%
per annum. As of June 30, 1999, there was outstanding approximately $850,000
for standby letters of credit. Borrowings under the agreement are secured by
liens on certain of the Company's assets. Covenants in connection with the
agreement impose restrictions and requirements related to, among other things,
maintenance of certain financial ratios, limitations on outside indebtedness,
profitability, payments of dividends and capital expenditures. The Company has
not yet decided how it will handle this facility upon its expiration.

   Rapiscan U.K. has a loan agreement with Midland Bank plc, which provides for
an overdraft facility up to a maximum amount of 2.0 million Pounds Sterling
(approximately $3.1 million at June 30, 1999) outstanding at any one time,
which amounts are secured by certain assets of Rapiscan U.K. At June 30, 1999,
no amounts were outstanding under the overdraft facility. Outstanding
borrowings bear interest at a base rate (7.75% at June 30, 1999) plus 1.5% per
annum. The agreement also provides for a 1.0 million Pounds Sterling
(approximately $1.6 million at June 30, 1999) facility for tender and
performance bonds and a 1.0 million Pounds Sterling (approximately $1.6 million
at June 30, 1999) facility for the purchase of forward exchange contracts.
These facilities are secured by certain assets of Rapiscan U.K. and the Company
has guaranteed Rapiscan U.K.'s obligations under the performance bond facility.
As of June 30, 1999, $277,000 was outstanding under the performance bond
facility and Rapiscan U.K. had purchased forward exchange contracts in the
amount of $200,000. The above facilities expire in January 2000 and the Company
believes that they will be renewed on the same or similar terms.

   OSI Singapore has a loan agreement with Indian Bank (Singapore), which
provides for an accounts receivable discounting facility for borrowing of up to
2.9 million Singapore dollars (approximately $1.7 million at June 30, 1999).
Borrowings under the line of credit bear interest at the bank's prime rate
(10.0% at June 30, 1999) plus 2.25%. The line of credit is terminable at any
time. As of June 30, 1999 there were no amounts outstanding under the line of
credit. Borrowings under the line of credit are collateralized by certain
assets of OSI Singapore and are guaranteed by certain officers of the Company.
Borrowings secured by intercompany receivables are guaranteed by the Company.

   AME has a loan agreement with Christiania Bank OG Kreditkasse which provides
for a revolving line of credit for borrowings of up to 5.0 million Norwegian
kroner (approximately $636,000 at June 30, 1999). As of June 30, 1999, no
amounts were outstanding under this line of credit. Borrowings under the line
of credit bear interest at a variable rate, which was 10.1% at June 30, 1999.

   OSI Malaysia has a loan agreement with the Hong Kong Bank Malaysia Berhad,
which provides for a bank guarantee line of credit for 2.5 million Malaysia
ringgits (approximately $658,000 at June 30, 1999) for performance bonds and
standby letters of credit, and a 1.0 million Malaysian ringgits overdraft
facility (approximately $263,000 at June 30, 1999). Borrowings under the
overdraft facility bear interest at the bank's base lending rate (9.5% at June
30, 1999) plus 2.25%. At June 30, 1999, the amount outstanding under the
performance bond facility was $310,000 and there were no amounts outstanding
under the overdraft facility. Borrowings under this agreement are secured by
certain assets of OSI Malaysia. These lines expire in October 1999 and the
Company believes that they will be renewed on the same or similar terms.

   OSI Malaysia has a loan agreement with Bank Utama, which provides for a
revolving line of credit of up to an amount of 1.5 million Malaysian ringgits
(approximately $395,000 as of June 30, 1999). Borrowings under the line of
credit bear interest at the bank's base lending rate (9.0% at June 30, 1999)
plus 1.75%. As of

                                       28
<PAGE>

June 30, 1999, no amounts were outstanding under this line of credit.
Borrowings under this agreement are secured by certain assets of OSI Malaysia
and are guaranteed by the Company. The line of credit will expire in February
2000 and the Company believes that it will be renewed on the same or similar
terms.

   Metorex Security has a loan agreement with a Finnish bank that provide for a
foreign currency overdraft facility up to 2.0 million Finnish markka
(approximately $347,000 at June 30, 1999). At June 30, 1999, approximately
$178,000 was outstanding under the overdraft facility. The agreement also
provides for 1.0 million Finnish Marks (approximately $174,000 at June 30,
1999) for tender and performance bonds. At June 30, 1999, approximately $26,000
was outstanding under the tender and performance bonds facility. Borrowings
under these facilities bear interest at the bank's prime lending rate (3% at
June 30, 1999) plus 1%. The above facilities expire in February 2000, and the
Company believes that they will be renewed at the same of similar terms.

   The Company believes that cash from operations, existing cash and lines of
credit will be sufficient to meet its cash requirements for the foreseeable
future.

Foreign Currency Translation

   The accounts of the Company's operations in Singapore, Malaysia, England,
Denmark, Finland, Norway and Canada are maintained in Singapore dollars,
Malaysian ringgits, Pounds Sterling, Danish kroner, Finnish markka, Norwegian
kroner and Canadian dollars, respectively. Foreign currency financial
statements are translated into U.S. dollars at current rates, with the
exception of revenues, costs and expenses, which are translated at average
rates during the reporting period. Gains and losses resulting from foreign
currency transactions are included in income, while those resulting from
translation of financial statements are excluded from income and accumulated as
a component of shareholder's equity. Transaction losses of approximately
$39,000 and $743,000 were included in income for fiscal 1998 and 1999,
respectively.

Importance of International Markets

   International markets provide the Company with significant growth
opportunities. However, the following events, among others, could adversely
affect the Company's financial results in subsequent periods: periodic economic
downturns in different regions of the world, changes in trade policies or
tariffs, and political instability. For the year ended June 30, 1999, overall
foreign currency fluctuations relative to the U.S. dollar had an immaterial
effect on the Company's consolidated revenues and results of operations. As a
result of changes in monetary policy in Malaysia, including the pegging of the
Malaysian ringgit to the U.S. dollar, the Company believes that its foreign
currency exposure in Malaysia will not be significant in the foreseeable
future. The Company continues to perform ongoing credit evaluations of its
customers' financial condition and, if deemed necessary, the Company requires
advance payments for sales. The Company is monitoring economic and currency
conditions around the world to evaluate whether there may be any significant
effect on its international sales in the future.

Inflation

   The Company does not believe that inflation has had a material impact on its
results of operations.

Market Risk

   The Company is exposed to certain market risks, which are inherent in the
Company's financial instruments and arise from transactions entered into in the
normal course of business. The Company may enter into derivative financial
instrument transactions in order to manage or reduce market risk in connection
with specific foreign currency denominated transactions. The Company does not
enter into derivative financial instrument transactions for speculative
purposes.

   The Company has investments in the common stock of certain companies whose
securities are publicly traded. Therefore, the Company faces fluctuations in
the value of these investments as the market price of these investees'
securities changes. The aggregate amount of all such investments is
approximately $1.7 million. At June 30, 1999, the fair market value of all such
investments was approximately $1.2 million.

                                       29
<PAGE>

   The Company is subject to interest rate risk on its short-term borrowings
under its bank lines of credit. Borrowings under these lines of credit do not
give rise to significant interest rate risk because these borrowings have short
maturities and are borrowed at variable interest rates. Historically, the
Company has not experienced material gains or losses due to interest rate
changes.

   The Company from time to time enters into foreign currency forward contracts
to hedge certain foreign currency transactions and commitments. These contracts
were not significant at June 30, 1999 and had a notional value of approximately
$200,000 with a net unrealized gain of approximately $5,000.

Year 2000 Compliance

   The Company has a comprehensive Year 2000 project designed to identify and
assess the risks associated with its information systems, products, operations
and infrastructure, suppliers, and customers that are not Year 2000 compliant,
and to develop, implement, and test remediation and contingency plans to
mitigate these risks. The project comprises of four phases: (1) identification
of risks, (2) assessment of risks, (3) development of remediation and
contingency plans, and (4) implementation and testing.

   The Company's Year 2000 project is currently in the assessment phase and,
with respect to certain information systems and products, is in the remediation
phase. The Company's Year 2000 project is being spearheaded by a special task
force comprised of a senior management team as well as other key personnel. The
task force meets on a regular basis to determine and implement the steps
necessary to insure that the Company becomes fully Year 2000 compliant.
Additionally, the Company has established task forces in each of its major
subsidiaries with designated Year 2000 management representation, which report
status to the Year 2000 committee. This mandate is in effect for foreign
subsidiaries as well as U.S. subsidiaries.

   The Company has upgraded its critical database and believes that it is Year
2000 compliant. The financial records of the Company's principal U.S.
subsidiaries, Rapiscan U.S.A., UDT Sensors and SMI have also been upgraded and
are Year 2000 compliant. Following an assessment of the Company's financial
records system, it was determined that each subsidiary will have its own Year
2000 compliant system. The estimated completion date for this implementation is
on or before October 31, 1999. The Company has completed an upgrade of the
telephone systems, including voice-mail software, for Rapiscan U.S.A. and UDT
Sensors. The cost of these upgrades to date has not been material. The
Enterprise Resource Planning software used by several of the Company's
operating subsidiaries has been certified as Year 2000 compliant.

   The Company is in the assessment and remediation phase of determining Year
2000 compliance of its own products, which are dependent on third party
suppliers and vendors for critical parts. The Company expects to complete this
assessment by September 30, 1999 and expects to be able to complete remediation
as required by October 31, 1999. Based on what the Company knows at this time,
DOS and Windows 95 are not Year 2000 compliant; therefore, the Company's
products which rely on these products are themselves not Year 2000 compliant.
The Company is in the process of acquiring and installing software, within the
Company's products, which is Year 2000 compliant. The Company's products which
are not presently Year 2000 compliant are not affected in terms of performance
in any material respect; however, archiving of information may be affected by
Year 2000 noncompliance. The Company's exposure exists with respect to its
products under warranty, which were manufactured prior to the software upgrade.
In such cases, the Company will offer its customers a software upgrade to a
Year 2000 compliant version. Until the assessment phase is completed, the
Company is not in a position to know if the costs of upgrading the software
used in the manufacture of its products or offering its customers such
upgrading will be material.

   Based on current estimates, the Company expects to have completed by
September 30, 1999 a full assessment of all hardware, operating systems and
software applications in use in the Company's information systems, operations
and infrastructure on a worldwide basis. Some upgrading is expected to be
required. The costs of such assessment and upgrading are not expected to be
material. Required upgrading is expected to be completed on or before October
31, 1999. In addition, the Company is in the process of obtaining Year 2000
compliance statements from the manufacturers of the Company's hardware and
software products.

                                       30
<PAGE>

   The Company believes that its greatest potential risks are associated with
(i) its information systems and systems embedded in its operations and
infrastructure; and (ii) its reliance on Year 2000 compliance by the Company's
vendors and suppliers. The Company is in the process of assessments of its
operations and infrastructure, and at present time no significant problems have
been identified. The Company has asked its critical vendors, suppliers and
customers to complete a Year 2000 survey to assess the status of their
compliance in order to assess the effect it could have on the Company. The
Company has completed distribution of surveys to its critical vendors and
suppliers and in the process of mailing follow-up requests to those vendors and
suppliers who failed to respond to the initial mailing. The Company has
distributed surveys to all of its critical customers and is in the process of
mailing follow-up requests to those customers who failed to respond to the
initial mailing. Due to slow responses from suppliers and customers, the
Company has not yet determined the full extent of contingency planning that may
be required. Based on the status of the assessments made and remediation plans
developed to date, the Company is not in a position to state the total cost of
remediation of all Year 2000 issues. Costs identified to date have not been
material. The Company does not currently expect the costs to be material, and
it expects to be able to fund the total costs through operating cash flows.
However, the Company has not yet completed all of its assessments, developed
remediation for all problems, developed all contingency plans, or completely
implemented or tested all of its remediation plans.

   Based on the Company's current analysis and assessment of the state of its
Year 2000 compliance, the Company's most reasonably likely worst case scenario
involves delays in shipping of parts, including critical parts, by certain of
the Company's vendors and suppliers. Such delays could cause the Company to
experience delays in shipping its products. The Company is in process of
formulating contingency plans based on review of compliance surveys from its
vendors and suppliers. These plans could include, among other things,
increasing inventory of critical parts in late 1999 to insure an adequate
supply is on hand to minimize shipping delays by the Company of its products.

   As the Year 2000 project continues, the Company may discover additional Year
2000 problems, may not be able to develop, implement, or test remediation or
contingency plans, or may find that the costs of these activities exceed
current expectations and become material. In many cases, the Company is relying
on assurances from suppliers that new and upgraded information systems and
other products will be Year 2000 compliant. The Company plans to test such
third-party products, but cannot be sure that its tests will be adequate or
that, if problems are identified, they will be addressed in a timely and
satisfactory way. Additionally, whereas, the Company has made every effort to
obtain Year 2000 compliance status from its critical suppliers and customers it
cannot enforce responses. In those cases where risks could exist, the necessary
steps will be taken either by reserve funding, building inventory or alternate
sources prior to the end of 1999.

   Because the Company uses a variety of information systems and has additional
systems embedded in its operations and infrastructure, the Company cannot be
sure that all of its systems will work together in a Year 2000 compliant
fashion. Furthermore, the Company cannot be sure that it will not suffer
business interruptions, either because of its own Year 2000 problems or those
of its customers or suppliers whose Year 2000 problems may make it difficult or
impossible for them to fulfill their commitments to the Company. If the Company
fails to satisfactorily resolve Year 2000 issues related to its products in a
timely manner, it could be exposed to liability to third parties. The Company
is continuing to evaluate Year 2000-related risks and will take such further
corrective actions as may be required.

                          INDEPENDENT AUDITORS' REPORT

OSI Systems, Inc.:

   We have audited the accompanying consolidated balance sheets of OSI Systems,
Inc. (the "Company") and its subsidiaries as of June 30, 1999 and 1998, and the
related consolidated statements of operations, shareholders' equity, and cash
flows for each of the three years in the period ended June 30, 1999. Our audits
also included the financial schedules listed at Item 14. 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 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, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company as of June 30,
1999 and 1998, and the results of its operations and its cash flows for each of
the three years in the period ended June 30, 1999 in conformity with generally
accepted accounting principles. Also, in our opinion, such financial statement
schedule, when considered in relation to the basic consolidated financial
statements taken as a whole, present fairly in all material respects the
information set forth therein.

                    YEARS ENDED JUNE 30, 1997, 1998 AND 1999

1. Summary of Significant Accounting Policies

 General

   OSI Systems, Inc. (formerly Opto Sensors, Inc.) and its subsidiaries
(collectively, the "Company") is a vertically integrated, worldwide provider of
devices, subsystems and end-products based on optoelectronic and silicon
pressure-sensor microstructure technology. The Company designs and manufactures
optoelectronic and pressure-sensor devices and value-added subsystems for
original equipment manufacturers ("OEMs") in a broad range of applications,
including security, medical diagnostics, telecommunications, gaming, office
automation, aerospace, computer peripherals and industrial automation. In
addition, the Company utilizes its optoelectronic technology and design
capabilities to manufacture security and inspection products and medical
imaging systems that it markets worldwide to end users. The Company markets its
security and inspection products under the "Rapiscan," "Secure" and "Metor"
brand names. These products are used to inspect baggage, cargo, people and
other objects for weapons, explosives, drugs and other contraband.

 Consolidation

   The consolidated financial statements include the accounts of OSI Systems,
Inc. and its majority-owned subsidiaries. All significant intercompany accounts
and transactions have been eliminated in consolidation. In October and December
1996, the Company purchased the minority interests of its two majority-owned
subsidiaries by exchanging 178,956 shares of common stock for the minority
shares of the subsidiaries. The Company also issued additional shares of the
Company's common stock to the selling shareholders of one of the subsidiaries.
The number of shares issued was based upon the pre-tax net income of the
subsidiary for the year ended June 30, 1997, and amounted to 27,654 shares.
These shares have been included in the number of shares issued for minority
interest acquisitions in the accompanying consolidated statement of
shareholders' equity. The excess of the fair value of the common stock issued
of $1,566,000 over the carrying value of the minority interest of $12,000 has
been recorded as goodwill and is being amortized over a period of 20 years.

   For the purpose of the consolidated statements of cash flows, the Company
considers all highly liquid investments purchased with a maturity of three
months or less to be cash equivalents.

 Investment Securities

   The Company's investment securities are composed of equity securities that
have been classified as available-for-sale securities. The equity securities
are carried at their fair market value based upon the quoted market prices of
those investments at June 30, 1999. Unrealized gains and losses on equity
securities are included in accumulated other comprehensive income.

 Concentrations of Credit Risk

   Financial instruments that potentially subject the Company to credit risk
consist primarily of cash, cash equivalents and accounts receivable. At June
30, 1999, approximately 62% of the Company's cash and cash equivalents were
held at one financial institution. The Company performs ongoing credit
valuations of its customers' financial condition and provides an allowance for
potential credit losses.

 Inventory

   Inventory is stated at the lower of cost or market; cost is determined on
the first-in, first-out method.

 Property and Equipment

   Property and equipment are stated at cost. Depreciation and amortization are
computed using the straight-line and accelerated methods over lives ranging
from three to ten years. Amortization of leasehold improvements is calculated
on the straight-line basis over the shorter of the useful life of the asset or
the lease term.

</TABLE>

   Goodwill and identified intangible assets are amortized on a straight-line
basis over periods ranging from 12 to 20 years.

   Software development costs incurred in the research and development of
software products are expensed as incurred until the technological feasibility
of the product has been established. After technological feasibility is
established, certain software development costs are capitalized. The software,
once developed, is a component that is included in x-ray security machines when
they are sold to customers. The Company amortizes these costs on a straight-
line basis over a two-year period. No software development costs were
capitalized during the three years ended June 30, 1999.

 Impairment of Long-Lived Assets

   The Company reviews long-lived assets, including goodwill, for impairment
whenever events or changes in circumstances indicate that the carrying amount
of the asset may not be recoverable. If the sum of the expected future cash
flows, undiscounted and without interest charges, is less than the carrying
amount of the asset, the Company recognizes an impairment loss based on the
estimated fair value of the asset. Impairment losses for Osteometer have been
disclosed in Note 3 to the financial statements.

 Income Taxes

   Deferred income taxes are provided for temporary differences between the
financial statement and income tax bases of the Company's assets and
liabilities, based on enacted tax rates. A valuation allowance is provided when
it is more likely than not that some portion or all of the deferred income tax
assets will not be realized.

 Fair Value of Financial Instruments

   The Company's financial instruments consist primarily of cash, accounts
receivable, accounts payable, and debt instruments. The carrying values of
financial instruments, other than debt instruments, are representative of their
fair values due to their short-term maturities. The carrying values of the
Company's long-term debt instruments are considered to approximate their fair
values because the interest rates of these instruments are variable or
comparable to current rates offered to the Company. The fair value of the
Company's senior subordinated debt cannot be determined due to the related-
party nature of the obligations.

 Foreign Exchange Instruments

   The Company's use of derivatives is limited to the purchase of foreign
exchange contracts in order to minimize foreign exchange transaction gains and
losses. The Company purchases forward contracts to hedge commitments to acquire
inventory for sale and does not use the contracts for trading purposes. As of
June 30, 1999, there was approximately $200,000 in outstanding foreign exchange
contracts. The estimated fair value of these contracts, based on quoted market
prices from banks, closely approximated their carrying value at June 30, 1999.

 Revenue Recognition

   The Company recognizes revenue upon shipment of its product.

 Foreign Currency Translation

   The accounts of the Company's operations in Singapore, Malaysia, Norway,
Denmark, Finland, Canada and the United Kingdom are maintained in Singapore
dollars, Malaysian ringgits, Norwegian kroner, Danish kroner, Finnish markka,
Canadian dollars and U.K. pounds sterling, respectively. Foreign currency
financial statements are translated into U.S. dollars at current rates, with
the exception of revenues, costs and expenses, which are translated at average
rates during the reporting period. Gains and losses resulting from foreign
currency transactions are included in income, while those resulting from
translation of financial statements are excluded from income and accumulated as
a component of shareholders' equity. Transaction gains (losses) of
approximately $68,000, $(39,000) and $(743,000) were included in income for the
years ended June 30, 1997, 1998 and 1999, respectively.

 Restructuring Costs

   The Company adopted a restructuring plan in the quarter ended March 31,
1999. In terms of the plan the Company recorded $458,000 of restructuring costs
associated primarily with the termination of certain employees and integration
of certain activities of subsidiaries. All of the restructuring costs have been
incurred and recorded before March 31, 1999.

 Earnings per Share

   The Company has adopted Statement of Financial Accounting Standards ("SFAS")
No. 128 "Earnings per Share." The Company has reflected the provisions of SFAS
No. 128 in the accompanying financial statements for all periods presented.
Earnings per common share are computed using the weighted average number of
shares outstanding during the period. Earnings per common share--assuming
dilution are computed using the weighted average number of shares outstanding
during the period and dilutive common stock equivalents from the Company's
stock option plans, and in the 1997 period common equivalent shares from
convertible debt and preferred stock, calculated using the treasury stock and
if converted methods.

   The following table reconciles the numerator and denominator used in
calculating earnings per share and earnings per common share--assuming
dilution.

 Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities," which revises
the accounting for derivative financial instruments. This statement requires
that all derivative instruments be recorded on the balance sheets at their fair
values. Changes in the fair value of derivatives will be recorded in income or
other comprehensive income. The Company is currently analyzing the impact of
this statement, which is required to be adopted in 2001, and does not expect it
to have a material impact on the Company's financial position or results of
operations.

 Use of 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.

2. Joint Ventures and Equity Investments

   In January 1995, the Company, together with an unrelated company, formed
ECIL-Rapiscan Security Products Limited, a joint venture organized under the
laws of India. The Company, the Company's chairman and the Company's chief
financial officer have a 36%, 10.5% and 4.5% ownership interest, respectively,
in the joint venture. The Company's investment of approximately $183,000
consists of an initial investment of $108,000 and the Company's equity in the
earnings of the joint venture since inception of $75,000.

                    YEARS ENDED JUNE 30, 1997, 1998 AND 1999


   The joint venture was formed for the purpose of the manufacture, assembly,
service and testing of x-ray security and other products. Some of the Company's
subsidiaries are suppliers to the joint venture partner, which in turn
manufactures and sells the resulting products to the joint venture utilizing
technology received from the subsidiary. The agreement provides for technology
transfer between the Company and the joint venture, subject to certain
restrictions.

   During the years ended June 30, 1998 and 1999, the Company earned a
technical fee from the joint venture in the amount of $144,000 and $107,000,
respectively. At June 30, 1999, $107,000 was unpaid and included in other
receivables in the accompanying consolidated financial statements.

   In August 1998, the Company invested $315,000, including professional fees
associated with the investment, in Square One, Inc. The Company's investment
including goodwill of $242,000 is accounted for under the equity method and
included in other assets in the accompanying financial statements. The
Company's equity in the losses of the investment through June 30, 1999 was not
significant. Square One, Inc. develops and manufactures infrared-based patient
monitoring devices and subsystems.

   During the year, the Company invested $1,002,000, including professional
fees associated with the acquisition, in TFT Medical, Inc. for an equity share
of 40.3%. The Company's investment of $1,002,000 includes goodwill of $740,000,
which is the excess of the purchase price over the Company's share of the net
assets acquired. At June 30, 1999, the Company's equity in the losses of the
investment is $187,000 and is included in selling, general and administrative
expenses. The investment and equity losses are included in other assets in the
accompanying financial statements. TFT Medical, Inc. develops new generation
pulse oximeter instruments and probes for use in the medical field.

3. Acquisitions

   On March 3, 1997, the Company acquired the capital stock of Advanced Micro
Electronics AS ("AME"), headquartered in Horten, Norway, from Industriinvestor
ASA. The cash purchase price amounted to $916,000. The acquisition has been
accounted for by the purchase method of accounting, and, accordingly, the
purchase price has been allocated to the assets acquired of $2,350,000 and
liabilities assumed of $2,022,000, based on the estimated fair values of the
assets and liabilities at the date of acquisition. The excess of the purchase
price over the fair value of net assets acquired is being amortized over a
period of 20 years.

   During fiscal 1998, the Company acquired the "Secure" product line from
ThermoSpectra Corporation. The cash purchase price amounted to $750,000. The
purchased assets include, among other things, equipment, inventory and
intellectual property rights relating to x-ray machines and x-ray backscatter
detection technology (including patents and patent applications).

   On September 2, 1998, the Company acquired the capital stock of Osteometer,
a Danish manufacturer of bone densitometers for the diagnosing of osteoporosis.
The cash purchase price amounted to $7,885,000, including professional fees
associated with the acquisition. The acquisition has been accounted for by the
purchase method of accounting, and, accordingly, based on the valuation
obtained, the purchase price has been allocated to the assets acquired of
$3,675,000 and liabilities assumed of $1,731,000, in-process research and
development of $1,957,000 and identified intangible assets of $3,984,000.
Osteometer experienced continued losses due to the worldwide decline in the
bone densometer market. As a result of the aforementioned circumstances, the
Company recorded an asset impairment charge of $5,189,000, which included the
write-off of $3,735,000 of goodwill and $1,454,000 of other assets. The asset
impairment charge was calculated as the difference between the carrying amount
of the assets and the expected net realizable value of the assets.

Subsequent to the year ended June 30, 1999, the Company decided to close the
manufacturing facilities of Osteometer in Denmark within the next several
months and currently intends to relocate certain of these operations to the
U.S. facilities of the Company. The Company will incur additional costs related
to this closure and relocation in fiscal 2000. Based on its assessment to date,
the Company currently estimates these costs to be in the range of $2,000,000 to
$2,700,000. As the Company continues to proceed with the closure and intended
relocation of these manufacturing facilities, it will be able to more
accurately estimate the range of these costs, which may change from the current
estimate.

   On November 4, 1998, the Company purchased the security products business of
Metorex Security of Espoo, Finland. The Company paid $4,715,000 in cash,
including professional fees associated with the acquisition. The Company may
pay up to an additional $1,500,000 in cash, at a later date, based upon future
sales. The acquisition has been accounted for by the purchase method of
accounting, and, accordingly, based on the valuation obtained, the purchase
price has been allocated to the assets acquired of $914,000, in-process
research and development of $204,000, and goodwill and identified intangible
assets of $3,597,000. Goodwill and identified intangible assets are amortized
over a period of 20 and 12 years, respectively.

   On November 17, 1998, the Company acquired all the outstanding stock of SMI,
a silicon pressure sensor manufacturer, from Exar Corporation of Fremont,
California. The Company paid $2,694,000 in cash, including professional fees
associated with the acquisition. The Company may pay up to an additional
$3,900,000 million in cash, at a later date, based on future sales. The
acquisition has been accounted for by the purchase method of accounting, and,
accordingly, based on the valuation obtained, the purchase price has been
allocated to the assets acquired of $806,000, in-process research and
development of $418,000 and identified intangible assets of $1,470,000.
Identified intangible assets are amortized over a period of 12 years.

   On December 11, 1998, the Company purchased most of the assets and assumed
certain liabilities of Corrigan, a Canadian security products manufacturer. The
Company paid $476,000 in cash, including professional fees associated with the
acquisition. The acquisition has been accounted for by the purchase method of
accounting, and, accordingly, the purchase price has been allocated to the
assets acquired of $1,117,000 and liabilities assumed of $751,000, based on the
estimated fair values of the assets and liabilities at the date of acquisition.
The excess of the purchase price over the fair value of the net assets acquired
is being amortized over a period of 20 years.

   On January 31, 1999, the Company purchased the product line of Aristo.
Aristo develops and manufactures new generation pulse oximeter probes for use
in the medical field. The purchase price amounted to $277,000 in cash,
including professional fees associated with the acquisition. The acquisition
has been accounted for by the purchase method of accounting, and, accordingly,
the purchase price has been allocated to the assets acquired of $250,000, based

that the Company will generate sufficient taxable income to realize its
deferred tax assets.

   The Company is involved in various claims and legal proceedings arising out
of the conduct of its business. In the opinion of the Company's management
after consultation with outside legal counsel, the ultimate disposition of such
proceedings, will not have a materially adverse effect on the Company's
consolidated financial position or future results of operations.

8. Stock Options

   The Company has two stock option plans. Under the 1987 plan, 1,050,000
shares of common stock have been reserved for the issuance of incentive stock
options to key employees, directors and officers of the Company. The price,
terms and conditions of each issuance are determined by the Board of Directors
with the advice of and input from the Compensation Committee.

   The 1997 plan was established in May 1997 and authorizes the grant of up to
850,000 shares of the Company's common stock in the form of incentive and
nonqualified options. Employees, officers and directors are eligible under this
plan, which is administered by the Board of Directors, which determines the
terms and conditions of each grant, with the advice of and input from the
Compensation Committee. The exercise price of nonqualified options may not be
less than 85% of the fair market value of the Company's common stock at the
date of grant. The exercise price of incentive stock options may not be less
than the fair market value of the Company's common stock at the date of grant.
The exercise price of incentive stock options granted to individuals that own
greater than 10% of the Company's voting stock may not be less than 110% of the
fair market value of the Company's common stock at the date of grant.

   Exercise periods for incentive and nonqualified options granted under this
plan may not exceed five years from the grant date.

   In November and December 1996, the Company granted stock options for the
purchase of 235,125 shares of the Company's common stock to certain employees
at prices below the $6.67 estimated fair market value at the date of grant. The
options were accelerated to vest immediately, and, accordingly, the Company has
recorded compensation expense for the year ended June 30, 1997, representing
the excess of the fair value of the Company's common stock at the date of grant
over the option exercise prices.

   The Company has adopted the disclosure-only provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." The estimated fair value of options
granted during 1997, 1998 and 1999 pursuant to SFAS No. 123 was approximately
$1,054,000, $768,000 and $1,272,000, respectively. Had the Company adopted SFAS
No. 123, pro forma net income would have been $4,058,000, $7,787,000 and
$(213,000), and pro forma net income per share would have been $0.64, $0.87 and
$(0.02) for 1997, 1998 and 1999, respectively. The fair value of each option
grant was estimated using the Black-Scholes option-pricing model with the
following weighted average assumptions: dividend yield of zero and volatility
of 71% (1998 and 1997, 44% and 0%, respectively), a risk-free interest rate of
5.67% (1998 and 1997, 5.47% and 6.53%, respectively) and expected option lives
of five years.

9. Stockholders' Equity

   In May 1997, the Company's Board of Directors authorized a 1.5-for-1 stock
split of the outstanding common stock. All share and per share numbers have
been adjusted to retroactively reflect the common stock split.

                    YEARS ENDED JUNE 30, 1997, 1998 AND 1999


   The preferred stock had a liquidation preference of $1.00 per share and was
otherwise entitled to the same voting, dividend and all other rights as the
common stock.

   In June 1997, in order to simplify the capital structure of the Company,
holders of the preferred stock converted each preferred share into 1.5 shares
(post-split) of common stock.

   In June 1997, the Company amended its articles of incorporation, which
articles authorize 10,000,000 shares of new preferred stock. Such preferred
stock has no par value, and no preferred shares are issued and outstanding at
June 30, 1998 and 1999.

   In connection with the acquisition of the minority interest of a subsidiary
in November 1996 (see Note 1), the Company granted the selling
shareholders/employees options to purchase 45,486 shares of the Company's
common stock at $11.50 per share. The options vest over four years from the
date of grant.

   The Company's Registration Statement for its initial public offering of
securities (File No. 333-29179) became effective on October 1, 1997, when the
Company issued 3,330,000 shares of its common stock for net proceeds of
approximately $41,000,000.

   In March 1999, the Board of Directors instituted a treasury stock program
under which the Company is authorized to purchase up to a total of 2,000,000
shares for reissuance in future proceeds. The Company purchased 85,000 shares
at a cost of $438,000 during fiscal 1999. These shares are disclosed as
treasury stock in the accompanying financial statements.

10. Related-Party Transactions

   The Company contracts with entities affiliated by common ownership to
provide messenger service and auto rental and printing services. The Company
also contracts for professional services from a firm that has a partner serving
as a member of the Company's Board of Directors. Included in cost of sales,
selling, general and administrative expenses for the years ended June 30, 1997,
1998 and 1999 are approximately $111,000, $99,000 and $103,000 for messenger
service and auto rental; $82,000, $186,000 and $76,000 for printing services;
and $11,000, $13,000 and $4,000 for professional services, respectively. For
the year ended June 30, 1997, the Company paid a one-time consulting fee
amounting to $100,000 to an entity that is a shareholder of the Company.

   Shareholders and other parties related to the Company had made loans to the
Company under agreements subordinating such loans to the Company's bank
borrowings (see Notes 4 and 5). Interest expense related to such borrowings was
approximately $146,000 for the year ended June 30, 1997.

11. Government Settlement

   During 1994, a subsidiary of the Company was notified that the U.S.
Department of Justice was conducting an investigation regarding the testing of
certain products that were sold by a subsidiary under government contracts. A
settlement of $1,500,000 was agreed to and was accrued and charged to
operations in the year ended June 30, 1994. The settlement is being paid in
five increasing installments, with the unpaid principal balance bearing
interest at the 52-week Treasury bill rate. The final payment under this
settlement was made during the year ended June 30, 1999.

12. Employee Benefit Plans

   OSI Systems, Inc. has a qualified employee retirement savings plan. The plan
provides for a contribution by the Company, which is determined annually by the
Board of Directors. In addition, the plan permits voluntary salary reduction
contributions by employees. The Company made no contributions to the plan for
the years ended June 30, 1998, 1997 and 1996. During 1995, a subsidiary in the
U.K. ("Rapiscan U.K.") transferred its existing employees from their former
owner's plan to a new plan, the Rapiscan U.K. Defined Benefit Plan, which
covers certain Rapiscan U.K. employees. The benefits under this plan are based
on years of service and the employees' highest 12 months' compensation during
the last five years of employment. Rapiscan U.K.'s funding policy is to make
the minimum annual contributions required by applicable regulations based on an
independent actuarial valuation sufficient to provide for benefits accruing
after that date. Pension expense for the years ended June 30, 1997, 1998 and
1999 was approximately $91,000, $138,000 and $106,000, respectively.

13. Subsequent Events

   The acquisition of Metorex Security provided for additional future payments,
up to $1,500,000 in cash, based on future sales. In July 1999, the Company paid
4,400,000 Finnish markka (approximately US $759,000) in lieu of the future
contingent payments.

   In July 1999, the Company entered into a non-exclusive patent license
agreement. The Company paid $450,000 for the patent license which expires in
2000. The Company may be required to make additional payments of up to $350,000
based on certain future orders and shipments.

   Subsequent to the end of the year, the Company purchased 247,500 additional
shares under the treasury stock repurchase plan at a total cost of $1,167,125.

15. Segment Information

   The Company has adopted SFAS No. 131, "Segment Disclosure." The Company has
reflected the provisions of SFAS No. 131 in the accompanying financial
statements for all periods presented. The Company believes that it operates in
two identifiable industry segments, namely optoelectronic and silicon pressure-
sensor devices and subsystems and medical imaging systems, and security and
inspection products. For the years ended June 30 1997, 1998 and 1999 external
revenues from optoelectronic and silicon pressure-sensor devices subsystems and
medical imaging systems were $42,879, $50,120 and $55,469, respectively.
Revenues from security and inspection systems were $34,749, $43,798 and $46,294
for the years ended June 30 1997, 1998 and 1999, respectively. Segment
information is provided by geographic area. As discussed in Note 1, the Company
is vertically integrated and is sharing common resources and facilities.
Therefore, with the exception of external revenues, therefore, meaningful
information is not available by industry or product segment.

              purposes.

                                      -6-
<PAGE>

       2.1.2  Making Line Advances: Each Advance under the Line of Credit shall
              be conclusively deemed to have been made at the request of and for
              the benefit of the Borrowers (i) when credited to any deposit
              account of any of the Borrowers maintained with the Bank or (ii)
              when paid in accordance with the Borrowers' written instructions.
              Subject to the requirements of Section 4, Advances shall be made
              by the Bank upon telephonic or facsimile request received from the
              Borrower, which request shall be received not later than 12:00
              p.m. (Pacific Standard Time) on the date specified for a Variable
              Rate Advance, as hereinafter defined, and 11:00 a.m. (Pacific
              Standard Time) two business days prior to the date specified for a
              Eurocurrency Advance or a Cost of Funds Advance, as hereinafter
              defined, each of which dates shall be a Business Day. The rates
              for a Eurocurrency Advance or a Cost of Funds Advance shall be set
              on the same Business Day as the request is received if received by
              11:00 a.m. and on the next Business Day if received after 11:00
              a.m.. Requests for Advances received after such time may, at the
              Bank's option, be deemed to be a request for an Advance to be made
              on the next succeeding Business Day for a Variable Rate Advance
              and the third succeeding Business Day for a Eurocurrency Advance
              or a Cost of Funds Advance.

       2.1.3  Repayment: On the Expiration Date, each Borrower hereby jointly
              and severally promises and agrees to pay to the Bank in full the
              aggregate unpaid principal amount of all Advances then
              outstanding, together with all accrued and unpaid interest
              thereon. provided, however, that any Advance denominated in
              Dollars must be repaid in Dollars and any Advance denominated in
              an Alternate Currency must be repaid in the same Alternate
              Currency.

       2.1.4  Interest on Advances: Interest shall accrue from the date of each
              Advance under the Line of Credit at one of the following rates, as
              quoted by the Bank and as elected by the Borrowers hereinbelow:

              (i)   Variable Rate Advances: For Advances denominated in Dollars,
                    a variable rate per annum equivalent to an index for a
                    variable interest rate which is quoted, published or
                    announced from time to time by the Bank as its reference
                    rate (the "Reference Rate") and as to which loans may be
                    made by the Bank at, below or above such Reference Rate (the
                    "Variable Rate"). Interest shall be adjusted concurrently
                    with any change in the Reference Rate. An Advance which
                    bears interest at the Variable Rate is hereinafter referred
                    to as a "Variable Rate Advance".

              (ii)  Eurocurrency Advances: For Advances denominated in Dollars
                    or in Alternate Currency, a fixed rate quoted by the Bank
                    for one, three, six, nine or twelve months or for such other
                    period of time that the Bank may quote and offer (provided
                    that any such period of time does not extend beyond the
                    Expiration Date) [the "Eurocurrency Interest Period"] for
                    Advances in the minimum amount of $100,000 and in $100,000
                    increments thereafter. Such interest rate shall be a
                    percentage, rounded upward to the nearest one-hundredth of
                    one percent, equivalent to the Bank's Eurocurrency Rate for
                    Dollars or such Alternate Currency plus the Applicable
                    Margin which is that rate determined by the Bank's Treasury
                    Desk as being the approximate rate at which the Bank could
                    purchase offshore Dollar deposits or Alternate Currency
                    deposits in an amount approximately equal

                                      -7-
<PAGE>

                    to the amount of the relevant Advance and for a period of
                    time approximately equal to the relevant Eurocurrency
                    Interest Period (adjusted for any and all assessments,
                    surcharges and reserve requirements pertaining to the
                    purchase by the Bank of such Alternate Currency deposits
                    [the "Eurocurrency Rate"]. An Advance which bears interest
                    at the Eurocurrency Rate is hereinafter referred to as the
                    "Eurocurrency Advance".

              (iii) Cost of Funds Advances. For Advances denominated in Dollars,
                    the Bank hereby agrees to make Advances to the Borrower, at
                    Borrower's election, at a fixed rate quoted by Bank in its
                    sole discretion for each Advance (the "Cost of Funds Rate")
                    plus the Applicable Margin and for such period of time that
                    the Bank may quote and offer, provided that any such period
                    of time does not extend beyond the Expiration Date (the
                    "Cost of Funds Interest Period") for Advances in the minimum
                    amount $100,000 and in $100,000 increments thereafter.
                    Advances based upon the Cost of Funds Rate are hereinafter
                    referred to as "Cost of Funds Advances". The Bank shall
                    provide the Borrower with a statement of the Borrower's Cost
                    of Funds 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.

              Eurocurrency Advances and Cost of Funds Advances are sometimes
              hereinafter referred to as a "Fixed Rate Advance".

              Interest on Variable Rate Advances and Cost of Funds Advances
              shall be paid in Dollars in monthly installments commencing on the
              first day of the month following the date of the first such
              Advance and continuing on the first day of each month thereafter.

              Interest on any Eurocurrency Advance shall be paid on the last day
              of the Eurocurrency Interest Period pertaining to such
              Eurocurrency Advance and shall be paid in Dollars or in the
              relevant Alternate Currency as the case may be. Each Borrower
              further jointly and severally promises and agrees to pay the Bank
              interest on any Eurocurrency Advance with an Eurocurrency Interest
              Period in excess of 90 days on a quarterly basis (i.e., on the
              last day of each 90-day period occurring in such Eurocurrency
              Interest Period) and on the last day of the relevant Eurocurrency
              Interest Period.

              If interest is not paid as and when it is due, it shall be added
              to the principal, become and be treated as a part thereof, and
              shall thereafter bear like interest.

     2.1.5    Notice of Election to Adjust Interest Rate: The Borrowers may
              elect that interest on a Fixed Rate Advance shall continue to
              accrue at a newly quoted Eurocurrency Rate or Cost of Funds Rate;

              liability to any Borrower in acting upon any telephonic notice
              referred to above that the Bank believes in good faith to have
              been given by a duly authorized officer or other person authorized
              to act on behalf of any Borrower and upon any borrowing,
              Redenomination or continuation by the Bank in accordance with this
              Agreement pursuant to any telephonic notice, each Borrower shall
              have effected the borrowing, redenomination or continuation of
              Advances hereunder. The Borrowers may elect that interest on a
              Fixed Rate Advance shall accrue at the Variable Rate; provided,
              however, that such notice shall be received by the Bank no later
              than one business day prior to the last day of the Interest Period
              pertaining to such Fixed Rate Advance, and provided further,
              however, that such Fixed Rate Advance shall be in Dollars or
              Redenominated in Dollars pursuant to the terms hereinbelow. If the
              Bank shall not have received notice (as prescribed herein) of
              Borrowers' election that interest on any Fixed Rate Advance shall
              continue to accrue at the newly quoted Eurocurrency Rate or Cost
              of Funds Rate or Variable Rate as the case may be, the Borrowers
              shall be deemed to have elected that interest thereon shall be
              adjusted to accrue at the Variable Rate then in effect and any
              Alternate Currency shall be Redenominated in Dollars.

     2.1.6    Redenomination of Advances: The Borrowers may, upon notice given
              to the Bank at least four Business Days prior to the date of the
              proposed Redenomination, request that a Eurocurrency Advance be

              provided, however, that any Redenomination shall be made on, and
              only on, the last day of an Interest Period for such Advances.
              Each such notice of request of a Redenomination ( "Notice of
              Redenomination") shall be by telecopier, telex or cable, confirmed
              immediately in writing, or may be by telephone if confirmed in
              writing by telecopy with the original of such writing deposited in
              the US mail or with an air courier on the same day, and the Bank
              shall not incur any liability to any Borrower in acting upon any
              telephonic notice referred to above that the Bank believes in good
              faith to have been given by a duly authorized officer or other
              person authorized to act on behalf of any Borrower and upon any
              borrowing, Redenomination or continuation by the Bank in
              accordance with this Agreement pursuant to any telephonic notice,
              the Borrowers shall have effected the borrowing, redenomination or
              continuation of Advances hereunder, specifying (i) the
              Eurocurrency Advance(s) to be Redenominated, (ii) the date of the
              proposed Redenomination, (iii) the Alternate Currency into which
              such Advances are to be Redenominated, and (iv) the duration of
              the Interest Period for such Advances upon being so Redenominated.
              In the case of a Notice of Redenomination which requests a
              Redenomination of Advances into an Alternate Currency, such
              Redenomination is subject to confirmation by Bank not later than
              the third Business Day before the requested date of such
              Redenomination that such Bank agrees to such Redenomination. which
              confirmation shall be notified to the Borrowers. If no
              confirmation is provided the Redenomination will not occur. Each
              Advance so requested to be Redenominated will be Redenominated, on
              the date specified therefor in such Notice of Redenomination, into
              an equivalent amount thereof in the currency requested in such
              Notice of Redenomination, such equivalent amount to be determined
              on such date in accordance with Section 2.7, and, upon being so
              Redenominated, will have an initial Interest Period as requested
              in such Notice of Redenomination.

     2.1.7    Prepayment:

              (i)   The Borrowers may prepay any Advance in whole or in part, at
                    any time and without penalty, provided, however, that: (i)
                    any partial prepayment shall first be applied, at the Bank's
                    option, to accrued and unpaid interest and next to the
                    outstanding principal balance; and (ii) during any period of
                    time in which interest is accruing on any Advance on the
                    basis of the Eurocurrency Rate or the Cost of Funds Rate, no
                    prepayment shall be made except on a day which is the last
                    day of the Interest Period pertaining thereto provided,
                    however, if the whole or any part of any Fixed Rate Advance
                    is prepaid by reason of acceleration or otherwise, the
                    Borrower shall jointly and severally upon the Bank's
                    request, promptly pay to and indemnify the Bank for all
                    costs and any loss actually incurred by the Bank, excluding
                    loss of profit on any margin, but including any loss
                    resulting from the re-employment of funds, sustained by the
                    Bank as a consequence of such prepayment, and provided
                    further, that any prepayment hereunder shall not be deemed
                    to be an event of default.

              (ii)  If, on the last day of any Interest Period, the equivalent
                    in Dollars of the aggregate principal amount of all
                    Eurocurrency Advances then outstanding when combined with
                    the aggregate principal amount of all Variable Rate Advances
                    and Cost of Funds Advances then outstanding exceeds the Line
                    of Credit, the Borrowers shall jointly and severally on such
                    last day prepay an aggregate principal amount of such
                    Advances to the Bank in an amount at least equal to such
                    excess, with accrued interest to the date of such prepayment
                    on the principal amount prepaid.

              (iii) The Bank shall be entitled to fund all or any portion of its
                    Advances in any manner it may determine in its sole
                    discretion, but all calculations and transactions hereunder
                    shall be conducted as though the Bank actually funded all
                    Advances through the purchase of dollar deposits bearing
                    interest at the same rate as U.S. Treasury securities in the
                    amount of the relevant Advance and in maturities
                    corresponding to the date of such purchase to the Expiration
                    Date hereunder.

     2.1.8    Indemnification for Eurocurrency Rate and Cost of Funds Rate
              Costs: During any period of time in which interest on any Advance
              is accruing on the basis of the Eurocurrency Rate or the Cost of
              Funds Rate, the Borrowers shall jointly and severally, within 15
              days of 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 requirement 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 the Alternate Currency or Dollars or
              cost of funds used by the Bank in quoting and determining the
              Eurocurrency Rate or the Cost of Funds Rate under this Agreement.
              Bank shall use its best efforts to provide Borrowers, in advance,
              with an estimate of any such costs which may potentially be
              incurred hereunder.

     2.1.9    Eurocurrency Rate or Cost of Funds Rate Infeasible: In the event
              that the Bank shall at any time determine that the accrual of
              interest on the basis of the

                                      -10-
<PAGE>

              Eurocurrency Rate or the Cost of Funds Rate (i) is infeasible at
              the time of any borrowing, continuation or Redenomination because
              the Bank is unable to determine the Eurocurrency Rate or Cost of
              Funds Rate due to the unavailability of Dollars or Alternate
              Currency deposits, contracts or time deposits in an amount
              approximately equal to the amount of the relevant Advance and for
              a period of time approximately equal to 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 Borrowers,
              in which event such Fixed Rate Advance shall be immediately
              prepaid but then may be converted or Redenominated into a Variable
              Rate Advance at the election of the Borrowers.

     2.1.10   Failure to Borrow: In the case of any Fixed Rate Advance, the
              Borrowers shall jointly and severally indemnify Bank against any
              loss, cost or expense incurred by Bank as a result of any failure
              to borrow on the date specified for such Fixed Rate Advance (other
              than as a result of Bank's failure to make funds available for
              such Advance), including, without limitation, any loss (excluding
              loss of anticipated profits), cost or expense incurred by reason
              of the liquidation or reemployment of deposits or other funds
              acquired by Bank to fund such Fixed Rate Advance to be made by
              Bank when such Fixed Rate Advance is not made on such date.

     2.1.11   Computations and Payments: Interest on any Advance shall be
              computed on the basis of 360 days per year, but charged on the
              actual number of days elapsed. Whenever any payment hereunder
              shall be stated to be due on a day other than a Business Day, such
              payment shall be made on the next succeeding Business Day, and
              such extension of time shall in such case be included in the
              computation of payment of interest; provided, however, if such
              extension would cause payment of interest on or principal of
              Eurocurrency Advances to be made in the next following calendar
              month, such payment shall be made on the immediately preceding
              Business Day.

     2.1.12   Loan Fee. The Borrowers promise and agree, concurrently with the
              execution and delivery of this Agreement, to pay to the Bank a
              non-refundable loan fee equal to .125% of the unused portion of
              the Line of Credit, payable quarterly in arrears on the last day
              of each March, June, September and December of each year.


2.2    LETTER OF CREDIT SUB-FACILITY

     2.2.1    Letter of Credit Sub-Facility: The Bank agrees to issue commercial
              and/or standby letters of credit (each a "Letter of Credit") on
              behalf of the Borrowers of up to $10,000,000.00. At no time,
              however, shall the total principal amount of all Advances
              outstanding under the Line of Credit, together with the total face
              amount of all Letters of Credit outstanding, less any partial
              draws paid by the Bank, exceed the Line of Credit.

              (i) Upon the Bank's request, the Borrowers shall promptly pay to
                  the Bank issuance fees and such other fees, commissions, costs
                  and any out-of-

                                      -11-
<PAGE>

              pocket expenses charged or incurred by the Bank with respect to
              any Letter of Credit.

        (ii)  The commitment by the Bank to issue Letters of Credit shall,
              unless earlier terminated in accordance with the terms of the
              Agreement, automatically terminate on the Expiration Date of the
              Letter of Credit and no Letter of Credit shall expire on a date
              which is 90 days after the Expiration Date.

        (iii) Each Letter of Credit shall be in form and substance satisfactory
              to the Bank and in favor of beneficiaries satisfactory to the
              Bank, provided that the Bank may refuse to issue a Letter of
              Credit due to the nature of the transaction or its terms or in
              connection with any transaction where the Bank, due to the
              beneficiary or the nationality or residence of the beneficiary,
              would be prohibited by any applicable law, regulation or order
              from issuing such Letter of Credit.

        (iv)  Prior to the issuance of each Letter of Credit, but in no event
              later than 10:00 a.m. (California time) on the day such Letter of
              Credit is to be issued (which shall be a Business Day), the
              Borrowers shall deliver to the Bank a duly executed form of the
              Bank's standard form of application for issuance of a letter of
              credit with proper insertions.

        (v)   The Borrowers shall, upon the Bank's request, 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 requirement 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
              any Letter of Credit. In the event that the Borrowers fail to pay
              any drawing under any Letter of Credit or the balances in the
              depository account or accounts maintained by the Borrowers with
              Bank are insufficient to pay such drawing, without limiting the
              rights of Bank hereunder or waiving any Event of Default caused
              thereby, Bank may, and Borrowers hereby authorize the Bank to
              create an Advance bearing interest at the rate or rates provided
              in Section 9.2 hereof to pay such drawing.

2.3   ACCEPTANCE SUB-FACILITY

  2.3.1 Acceptance Sub-Facility: The Borrowers may from time to time request the
        Bank to accept one or more drafts drawn on the Bank for the account of
        the Borrowers (each an "Acceptance") of up to $5,000,000. At no time,
        however, shall the total principal balance of all Acceptances
        outstanding, together with the total face amount of all outstanding
        Letters of Credit less any partial draws paid by the Bank, exceed the
        sum of $10,000,000.00 and, together with the total principal balance of
        all Advances outstanding under the Line of Credit, exceed the Line of
        Credit.

        (i)   Requests for Acceptances. Each request for an Acceptance shall be
              made in writing or by telephone confirmed in writing (each a
              "Request"), shall be irrevocable, and shall involve one or more
              drafts as described below. Each Request shall be delivered or
              communicated to the Bank no

                                      -12-
<PAGE>

       later than 10:00 a.m. (California time) on the day (which shall be a
       business day) on which the creation of an Acceptance is requested. By
       making any such Request, the Borrowers agree that all matters relating to
       each such Acceptance shall be governed hereby and the Borrowers restate
       all warranties and representations made by the Borrower herein as if made
       on the date of the Request and on the date that the Acceptance is
       created.

(ii)   Acceptances. Each Acceptance shall be created upon a Request by the
       Bank's acceptance of a draft in form and substance satisfactory to the
       Bank (each a "Draft"). Each Draft shall: (i) be drawn on the Bank by or
       on behalf or for the account of the Borrowers in accordance with the
       provisions hereof ; (ii) have a minimum face amount of $100,000.00; (iii)
       be for the purpose of financing only those transactions permitted by
       Subsection 7 of Section 13 of the Federal Reserve Act, as amended from
       time to time; and (iv) mature not more than 180 days after the date
       thereof (provided that, if such date is not a Business Day, the maturity
       shall be extended to the next succeeding Business Day). However, no Draft
       shall mature after the Expiration Date. The Borrowers hereby warrant that
       any Acceptances relating to the importation or exportation of goods or
       relating to the domestic shipment of goods shall: (i) not have a term in
       excess of the period of time which is usual and reasonably necessary to
       finance transactions of the character of the underlying import or export
       transaction or the underlying domestic shipment; (ii) not, together with
       all other Acceptances relating to any such shipment, have an aggregate
       face amount exceeding the CIF value of such shipment; and (iii) not be
       created more than 30 days after the date of shipment of goods to which
       such Acceptance relates. Acceptances relating to the storage of goods
       shall be subject to the further conditions that: (i) at the time such
       Acceptance is created, the goods being stored are covered by a warehouse
       receipt issued by a bonded warehouse independent of the Borrowers and
       acceptable to the Bank; (ii) the goods covered by the warehouse receipt
       are readily marketable staples (as such term is defined in Section 13 of
       the Federal Reserve Act by the Board of Governors of the Federal Reserve
       System or by Federal Reserve Bulletins) held pending a reasonably
       immediate sale, distribution or shipment; and (iii) the face amount of
       the Acceptance relating to such goods does not exceed the fair market
       value of the goods.

(iii)  Acceptance Liability. The Borrowers are obligated, and hereby
       unconditionally promise and agree, to pay the Bank, on the maturity date
       of each Acceptance or on such earlier date as may be required pursuant
       hereto, the face amount of each such Acceptance.

(iv)   Acceptance Commissions. The Borrowers agree, upon acceptance by the Bank
       of each Draft and as a condition precedent to such Acceptance, to pay to
       the Bank a fee (the "Commission") in an amount equal to 1.5% per annum of
       the face amount of each Acceptance calculated on the basis of 360 days
       per year for the actual number of days (including the first day but
       excluding the last day) during the period which is for the term of the
       Draft.

                                      -13-
<PAGE>

          (v)    Discount of Acceptances. The Bank agrees to discount any
                 Acceptance that is created and presented to it for discount at
                 a rate quoted by the Bank at the time the Acceptance is
                 presented to the Bank for discount and for a similar dollar
                 amount and a similar maturity as the Draft being presented to
                 the Bank by the Borrowers for acceptance (the "Acceptance
                 Discount Rate"). On the date any such Acceptance is presented
                 for discount, the Bank shall: (i) cause the aggregate
                 discounted amount (less any Commission then payable by the
                 Borrowers to the Bank hereunder) to be made available to the
                 Borrowers by crediting such amount to the Borrowers' demand
                 deposit account maintained with the Bank, and (ii) advise the
                 Borrowers of the Acceptance Discount Rate at which the Bank
                 discounted such Acceptance. The Bank shall have the right, in
                 its sole discretion, to sell, rediscount, hold or otherwise
                 deal with or dispose of any such Acceptance discounted by it.

          (vi)   Acceptance Collateral. Each Draft accepted by the Bank shall be
                 secured by a security interest in the goods (as defined in the
                 California Uniform Commercial Code) involved in the transaction
                 out of which the Acceptance arose to the extent that such a
                 security interest is either required by the Bank or in order
                 that the relevant Acceptance conform to the requirements of
                 Section 13 of the Federal Reserve Act.

          (vii)  Future Assessments. The Borrowers shall, within 15 days of the
                 Bank's written request, 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
                 requirement 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 any Acceptance. Bank shall use its best efforts to provide
                 Borrowers, in advance, with an estimate of any such costs which
                 may potentially be incurred hereunder.

2.4    FOREIGN EXCHANGE SUB-FACILITY

   2.4.1  Foreign Exchange Sub-Facility: The Bank agrees to enter into FX
          Transactions with the Borrowers, at the Borrowers' request therefor
          made prior to the Expiration Date, provided however, that at no time
          shall the aggregate FX Risk Liability of the Borrowers exceed the FX
          Limit, and provided further, at no time shall the aggregate FX Risk
          Liability combined with the total face amount of all Letters of Credit
          outstanding, less any partial draws paid by the Bank, together with
          the total principal balance of all Acceptances outstanding, together
          with the total principal amount of all outstanding Advances, exceed
          the Line of Credit. Each FX Transaction shall be used to hedge the
          Borrowers' foreign exchange exposure.

          (i)    Requests. Each request for a FX Transaction shall be made by
                 telephone to the Bank's Treasury Department ("Request"), shall
                 specify the Foreign Currency to be purchased or sold, the
                 amount of such Foreign Currency and the Settlement Date. Each
                 Request shall be communicated to the Bank no later than 3:00
                 p.m. California time on the Business Day on which the FX
                 Transaction is requested.

                                      -14-
<PAGE>

            (ii)  Tenor. No FX Transaction shall have a Settlement Date which is
                  more than 365 days after the date of entry into such FX
                  Transaction.

            (iii) Availability. Bank may refuse to enter into a FX Transaction
                  with the Borrowers where the Bank, at its sole discretion,
                  determines that (1) the requested Foreign Currency is
                  unavailable, or (2) the Bank is not then dealing in the
                  requested Foreign Currency, or (3) the Bank would be
                  prohibited by any applicable law, rule, regulation or order
                  from purchasing such Foreign Currency.

            (iv)  Payment. Payment is due on the Settlement Date of the relevant
                  FX Transaction. The Bank is hereby authorized by the Borrowers
                  to charge the full settlement price of any FX Transaction
                  against the depository account or accounts maintained by the
                  Borrowers with the Bank on the Settlement Date. In the event
                  that the Borrowers fail to pay the settlement price of any FX
                  Transaction on the Settlement Date or the balances in the
                  depository account or accounts maintained with Bank are
                  insufficient to pay the settlement price, without limiting the
                  rights of Bank hereunder or waiving any Event of Default
                  caused thereby, Bank may , and Borrowers hereby authorize Bank
                  to, create an Advance bearing interest at the Variable Rate to
                  pay the settlement price on the Settlement Date.

            (v)   Increased Costs. Borrowers shall, within 15 days of the Bank's
                  written request promptly pay to and reimburse the Bank for all
                  costs incurred and payments made by the Bank by reason of any
                  assessment, reserve, deposit, capital maintenance or similar
                  requirement 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 any FX Transaction. Bank shall use its best efforts to
                  provide Borrowers, in advance, with an estimate of any such
                  costs which may potentially be incurred hereunder.

            (vi)  Impossibility of Performance. In the event that the Borrowers
                  or the Bank cannot perform under a FX Transaction due to force
                  majeure or an act of State or it becomes unlawful or
                  impossible to perform, all in the good faith judgement of the
                  Borrowers or the Bank, then upon notice to the other party,
                  the Borrowers or the Bank may require the close-out and
                  liquidation of the affected FX Transaction in accordance with
                  the provisions of this Agreement

2.5.2  Equipment Account: The Bank shall maintain on its books a record of
       account in which the Bank shall make entries for each Advance and such
       other debits and credits as shall be appropriate in connection with the
       Equipment Purchase Facility (the "Equipment Account").

2.5.3  Security Interest in Equipment. The Borrowers, shall execute and deliver
       to the Bank, security agreements, financing statements, disbursement
       instructions and such other documents and instruments which the Bank may
       require with respect to such Advance and the perfection of the Bank's
       security interest in the Equipment pertaining to such Advance.

2.5.4  Repayment: Unless sooner due in accordance with the terms of the
       Agreement, on the Expiration Date, each Borrower hereby jointly and
       severally promises and agrees to pay to the Bank in full the aggregate
       unpaid principal amount of all Advances then outstanding hereunder,
       together with all accrued and unpaid interest thereon.

2.5.5  Interest on Advances: Interest shall accrue from the date of each Advance
       under the Equipment Purchase Facility at one of the following rates, as
       quoted by the Bank and as elected by the Borrowers pursuant to Subsection
       (i) or Subsection (ii) or Subsection (iii) below:

       (i)   Variable Rate Advances: A variable rate per annum equivalent to the
             ----------------------
             Reference Rate (the "Variable Rate"). Interest shall be adjusted
             concurrently with any change in the Reference Rate. An Advance
             based upon the Variable Rate is hereinafter referred to as a
             "Variable Rate Advance".

       (ii)  Fixed Rate Advances: A fixed rate per annum quoted by the Bank for
             -------------------
             30, 60, 90 or 180 days or for such other period of time that the
             Bank may quote and offer (provided that any such period of time
             does not extend beyond the Expiration Date) (the "Interest Period")
             for Advances in the minimum amount of $100,000.00. Such interest
             rate shall be a percentage approximately equivalent to the
             Applicable Margins plus the rate which the Bank determines in its
             sole and absolute discretion to be equal to the Bank's cost of
             acquiring funds (adjusted for any and all assessments, surcharges
             and reserve requirements pertaining to the borrowing or purchase by
             the Bank of such funds) in an amount approximately equal to the
             amount of the relevant Advance and for a period of time
             approximately equal to the relevant Interest Period (the "Fixed
             Rate"). Advances based upon the Fixed Rate are hereinafter referred
             to as "Fixed Rate Advances".

       (iii) LIBOR Advances: A fixed rate quoted by the Bank for one week, 1, 2,
             --------------
             3, or 6 months or for such other period of time that the Bank may
             quote and offer (provided that any such period of time does not
             extend beyond the Expiration Date) (the "LIBOR Interest Period")
             for Advances in the minimum amount of $100,000.00. Such interest
             rate shall be a percentage approximately equivalent to the
             Applicable Margin plus the Bank's LIBOR Rate which is that rate
             determined by the Bank's Treasury Desk as being the arithmetic mean
             (rounded upwards, if necessary, to the nearest whole multiple of
             one-sixteenth of one percent (1/16%)) of the U. S. dollar London

             Interbank Offered Rates for such period appearing on page 3750 (or
             such other page as may replace page 3750) of the Telerate screen at
             or about 11:00 a.m. (London time) on the second Business Day prior
             to the first days of such period (adjusted for any and all
             assessments, surcharges and reserve requirements) (the "LIBOR
             Rate"). An Advance based upon the LIBOR Rate is hereinafter
             referred to as a "LIBOR Advance".

       Interest on any Advance shall be computed on the basis of 360 days per
       year, but charged on the actual number of days elapsed.

       Each Borrower hereby jointly and severally promises and agrees to pay
       interest in arrears on Variable Rate Advances on the last calendar day of
       each month.

       Interest on any LIBOR Advance or Fixed Rate Advance with a LIBOR Interest
       Period or Interest Period of 3 months or less shall be paid on the last
       day of the LIBOR Interest Period or Interest Period as the case may be.
       The Borrowers further promise and agree to pay the Bank interest on any
       LIBOR Advance or Fixed Rate Advance with a LIBOR Interest Period or
       Interest Period in excess of 3 months on a quarterly basis (i.e., on the
       last day of each 3 month period occurring in such LIBOR Interest Period
       or Interest Period) and on the last day of the LIBOR Interest Period or
       Interest Period.

       If interest is not paid as and when it is due, it shall be added to the
       principal, become and be treated as a part thereof, and shall thereafter
       bear like interest.

2.5.6  Notice of Borrowing: Upon written notice which shall be received by the
       Bank at or before 2:00 p.m. (California time) on a Business Day, the

            is requested to be made, such Variable Rate Advance or Fixed Rate
            Advance may, at the Bank's option, be made on the next Business Day.

       (ii) A LIBOR Advance: Notice of any LIBOR Advance shall be received by
            ---------------
            the Bank no later than two Business Days prior to the day (which
            shall be a Business Day) on which the Borrowers request such LIBOR
            Advance to be made.

2.5.7  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 Borrowers may elect:

       (i)  That interest on a Variable Rate Advance shall be adjusted to accrue

       (ii)  That interest on a Variable Rate Advance shall be adjusted to
             accrue at the LIBOR Rate; provided, however, that such notice shall

             the Business Day on which the Borrowers request that interest be
             adjusted to accrue at the LIBOR Rate.

       (iii) That interest on a Fixed Rate Advance shall continue to accrue at a
             newly quoted Fixed Rate 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 2:00 p.m. on the last day of the
             Interest Period pertaining to such Fixed Rate Advance. If the Bank
             shall not have received notice (as prescribed herein) of the
             Borrowers' election that interest on any Fixed Rate Advance shall
             continue to accrue at the newly quoted Fixed Rate as the case may
             be the Borrowers shall be deemed to have elected that interest
             thereon shall be adjusted to accrue at the Variable Rate upon the
             expiration of the relevant Interest Period pertaining to such
             Advance.

       (iv)  That (i) interest on a Fixed Rate Advance shall accrue at a newly
             quoted LIBOR Rate or (ii) interest on a LIBOR Advance shall
             continue to accrue at a newly quoted Fixed Rate or LIBOR Rate 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
             relevant Interest Period or LIBOR Interest Period, as applicable.
             If the Bank shall not have received notice as prescribed herein of
             the Borrowers' election that interest on (x) any Fixed Rate Advance
             shall accrue interest at a newly quoted LIBOR Rate or at a newly
             quoted Fixed Rate pursuant to subparagraph (c) hereinabove; or (y)
             any LIBOR Advance shall continue to accrue at the newly quoted
             Fixed Rate or LIBOR Rate as the case may be, the Borrowers shall be
             deemed to have elected that interest thereon shall be adjusted to
             accrue at the Variable Rate upon the expiration of the relevant
             Interest Period or LIBOR Interest Period pertaining to such
             Advance.

2.5.8  Prepayment: The Borrowers may prepay any Advance in whole or in part, at
       any time and without penalty, provided, however, that: (i) any partial
       prepayment shall first be applied at the Bank's option, to accrued and
       unpaid interest and next to the outstanding principal balance; and (ii)
       during any period of time in which interest is accruing on any Advance on
       the basis of the LIBOR Rate or Fixed Rate, no prepayment shall be made
       except on a day which is the last day of the LIBOR Interest Period or
       Interest Period pertaining thereto. if the whole or any part of any LIBOR
       Advance or Fixed Rate Advance is prepaid by reason of acceleration or
       otherwise, the Borrower shall jointly and severally upon the Bank's
       request, promptly pay to and indemnify the Bank for all costs and any
       loss actually incurred by the Bank, excluding loss of profit on any
       margin, but including any loss resulting from the re-employment of funds,
       sustained by the Bank as a consequence of such prepayment, and provided
       further, that any prepayment hereunder shall not be deemed to be an event
       of default.

       The Bank shall be entitled to fund all or any portion of its Advances in
       any manner it may determine in its sole discretion, but all calculations
       and transactions hereunder shall be conducted as though the Bank actually
       funded all Advances

                                      -18-
<PAGE>

        through the purchase of dollar deposits bearing interest at the same
        rate as U.S. Treasury securities in the amount of the relevant Advance
        and in maturities corresponding to the date of such purchase to the
        Expiration Date hereunder.

2.5.9   Indemnification for LIBOR Rate or Fixed Rate Costs: During any period of
        time in which interest on any Advance is accruing on the basis of the
        LIBOR Rate or Fixed Rate, the Borrowers shall, within 15 days of the
        Bank's written request, 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 requirement 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
        LIBOR Rate or Fixed Rate. Bank shall use its best efforts to provide
        Borrowers, in advance, with an estimate of any such costs which may
        potentially be incurred hereunder.

2.5.10  Conversion from LIBOR Rate or Fixed 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 LIBOR Rate or Fixed Rate (i) has become infeasible
        because the Bank is unable to determine the LIBOR Rate or Fixed 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 Advance and for a period of time approximately equal to the
        relevant LIBOR Interest Period or Interest Period as the case may be or
        (ii) is or has become unlawful 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 promptly give telephonic notice thereof (confirmed
        in writing) to the Borrowers, in which event any Advance bearing
        interest at either the LIBOR Rate or Fixed Rate as the case may be shall
        be deemed to be a Variable Rate Advance and interest shall thereupon
        immediately accrue at the Variable Rate and shall continue at such rate
        until the Bank determines that the LIBOR Rate or Fixed Rate is no longer
        infeasible or unlawful.

2.5.11  Term Loan Conversion: The Borrowers may, by giving written notice to the
        Bank at any time and from time to time, convert the principal balance
        outstanding under the Equipment Purchase Facility as of the Expiration
        Date of Equipment Purchase Facility to be payable on a term loan basis.
        The term loan (the "Term Loan") shall be in the amount of such
        outstanding principal balance and be for a term of 60 months and shall
        be evidenced by a promissory note in form and substance satisfactory to
        the Bank (the "Equipment Term Note", attached hereto as Exhibit 1).
        Accrued and unpaid interest under the Equipment Purchase Facility shall
        be paid to the Bank concurrently with the Borrowers' execution of the
        Term Note. In addition to the short term fixed rates not to exceed 12
        months, the Borrower may fix the rate for the entire 60 month term loan
        at a Cost of Funds plus 1.50% or a Federal Funds plus 1.50%. For the
        Federal Funds Rate to apply a SWAP Agreement, which includes an ISDA
        Master Agreement with schedule to the Separate Master Agreement and a
        certified corporate resolution for such transaction, secured with a
        blanket lien will be required. Interest shall accrue and principal and
        interest shall be paid in accordance with the terms and provisions of
        the Term Note.

          to the Borrowers from time to time from the date hereof to November
          30, 1999, at which time the Acquisition Line must be paid in full or
          termed out pursuant to Section 2.6.11, and again the draw down period
          will be extended one more year to November 30, 2000, which is the

          $15,000,000.00 or the equivalent in Alternate Currency (the
          "Acquisition Line of Credit"). Within the foregoing limits, the
          Borrowers may borrow, partially or wholly prepay, but may not
          reborrow, under this Section 2.1. Proceeds of the Acquisition Line of
          Credit shall be used to acquire companies in related lines of business
          as the Borrowers or that are involved in a manufacturing process or
          technology similar to those used by the Borrowers, provided that each
          such Advance shall be limited to $5,000,000 per transaction hereunder
          and subject to the following conditions.

                 and $30 million in any fiscal year thereafter must be approved
                 by the Bank.

          (iv)   The purchase price of each acquisition may not exceed $25
                 million without Bank approval.

          (v)    The cash component of each acquisition may not exceed $15
                 million without Bank's prior written approval.

          (vi)   The business acquired must be in a related line of business as
                 the Borrowers or involve manufacturing processes or technology

          (vii)  The Bank will have a first priority lien on assets acquired in
                 domestic acquisitions and stock acquired in a domestic stock
                 purchase will be assigned to Bank in a separate security
                 agreement. The Bank will not have any lien on assets acquired

                 in a foreign stock purchase will not be assigned to Bank.

          (viii) Borrower shall provide Bank with a written certification that
                 all the above conditions are in compliance and provide a
                 proforma cash flow schedule of acquired company with detail of
                 expense reduction which results in a

                                      -20-
<PAGE>

                 positive EBITDA.

            (ix) A funding fee equal to 0.25% at funding.

Prior acquisitions that had terms exceeding the terms of this Section or terms
that were violations of the prior loan agreements are hereby waived on a one
time basis and such waiver shall not be deemed a waiver of any future violations
or terms of this Agreement.

            deemed to have been made at the request of and for the benefit of
            the Borrowers (i) when credited to any deposit account of any of the
            Borrowers maintained with the Bank or (ii) when paid in accordance
            with the Borrowers' written instructions. Subject to the
            requirements of Section 4, Advances shall be made by the Bank upon
            telephonic or facsimile request received from the Borrower, which
            request shall be received not later than 12:00 p.m. (Pacific
            Standard Time) on the date specified for a Variable Rate Advance, as
            hereinafter defined, and 11:00 a.m. (Pacific Standard Time) two
            business days prior to the date specified for a Eurocurrency Advance
            or a Cost of Funds Advance, as hereinafter defined, each of which
            dates shall be a Business Day. The rates for a Eurocurrency Advance
            or a Cost of Funds Advance shall be set on the same Business Day as
            the request is received if received by 11:00 a.m. and on the next
            Business Day if received after 11:00 a.m.. Requests for Advances
            received after such time may, at the Bank's option, be deemed to be
            a request for an Advance to be made on the next succeeding Business
            Day for a Variable Rate Advance and the third succeeding Business
            Day for a Eurocurrency Advance or a Cost of Funds Advance.

     2.6.3  Repayment: On November 30, 1999, and on the Expiration Date, each
            Borrower hereby jointly and severally promises and agrees to pay to
            the Bank in full the aggregate unpaid principal amount of all
            Advances then outstanding, together with all accrued and unpaid
            interest thereon, provided, however, that any Advance denominated in
            Dollars must be repaid in Dollars and any Advance denominated in an
            Alternate Currency must be repaid in the same Alternate Currency.

     2.6.4  Interest on Advances: Interest shall accrue from the date of each
            Advance under the Acquisition Line of Credit at Variable Rate or at
            the Eurocurrency Rate or Cost of Funds Rate plus the Applicable
            Margin, each as quoted by the Bank and as elected by the Borrowers
            hereinbelow:

            Eurocurrency Advances and Cost of Funds Advances are sometimes
            hereinafter referred to as a "Fixed Rate Advance".

            Interest on Variable Rate Advances and Cost of Funds Advances shall
            be paid in Dollars in monthly installments commencing on the first
            day of the month following the date of the first such Advance and
            continuing on the first day of each month thereafter.

            Interest on any Eurocurrency Advance shall be paid on the last day
            of the Eurocurrency Interest Period pertaining to such Eurocurrency
            Advance and shall be paid in Dollars or in the relevant Alternate
            Currency as the case may be. Each Borrower further jointly and
            severally promises and agrees to pay the Bank interest on any
            Eurocurrency Advance with an Eurocurrency Interest Period in excess
            of

                                      -21-
<PAGE>

       90 days on a quarterly basis (i.e., on the last day of each 90-day period
       occurring in such Eurocurrency Interest Period) and on the last day of
       the relevant Eurocurrency Interest Period.

       If interest is not paid as and when it is due, it shall be added to the
       principal, become and be treated as a part thereof, and shall thereafter
       bear like interest.

2.6.5  Notice of Election to Adjust Interest Rate: The Borrowers may elect that
       interest on a Fixed Rate Advance shall continue to accrue at a newly
       quoted Eurocurrency Rate or Cost of Funds Rate; provided, however, that
       such notice shall be received by the Bank no later than 11:00 a.m. two
       business days prior to the last day of the Eurocurrency Interest Period
       for a Eurocurrency Advance and 1:00 p.m. one business day prior to the
       last day of a Cost of Funds Interest Period for a Cost of Funds Advance.
       Such notice may be by telephone if confirmed in writing by telecopy with
       the original of such writing deposited in the US mail or with an air
       courier on the same day. The Bank shall not incur any liability to any
       Borrower in acting upon any telephonic notice referred to above that the
       Bank believes in good faith to have been given by a duly authorized
       officer or other person authorized to act on behalf of any Borrower and
       upon any borrowing, Redenomination or continuation by the Bank in
       accordance with this Agreement pursuant to any telephonic notice, each
       Borrower shall have effected the borrowing, redenomination or
       continuation of Advances hereunder. The Borrowers may elect that interest
       on a Fixed Rate Advance shall accrue at the Variable Rate; provided,
       however, that such notice shall be received by the Bank no later than one
       business day prior to the last day of the Interest Period pertaining to
       such Fixed Rate Advance, and provided further, however, that such Fixed
       Rate Advance shall be in Dollars or Redenominated in Dollars pursuant to
       the terms hereinbelow. If the Bank shall not have received notice (as
       prescribed herein) of Borrowers' election that interest on any Fixed Rate
       Advance shall continue to accrue at the newly quoted Eurocurrency Rate or
       Cost of Funds Rate or Variable Rate as the case may be, the Borrowers
       shall be deemed to have elected that interest thereon shall be adjusted
       to accrue at the Variable Rate then in effect and any Alternate Currency
       shall be Redenominated in Dollars.

2.6.6  Redenomination of Advances: The Borrowers may, upon notice given to the
       Bank at least four Business Days prior to the date of the proposed
       Redenomination, request that a Eurocurrency Advance be Redenominated from
       Dollars into an Alternate Currency or from an Alternate Currency into
       Dollars or another Alternate Currency; provided, however, that any
       Redenomination shall be made on, and only on, the last day of an Interest
       Period for such Advances. Each such notice of request of a Redenomination
       ("Notice of Redenomination") shall be by telecopier, telex or cable,
       confirmed immediately in writing, or may be by telephone if confirmed in
       writing by telecopy with the original of such writing deposited in the US
       mail or with an air courier on the same day, and the Bank shall not incur
       any liability to any Borrower in acting upon any telephonic notice
       referred to above that the Bank believes in good faith to have been given
       by a duly authorized officer or other person authorized to act on behalf
       of any Borrower and upon any borrowing, Redenomination or continuation by
       the Bank in accordance with this Agreement pursuant to any telephonic
       notice, the Borrowers shall have effected the borrowing, redenomination
       or continuation of Advances hereunder, specifying (i) the Eurocurrency
       Advance(s) to be Redenominated, (ii) the date of

                                      -22-
<PAGE>

       the proposed Redenomination, (iii) the Alternate currency into which such
       Advances are to be Redenominated, and (iv) the duration of the Interest
       Period for such Advances upon being so Redenominated. In the case of a
       Notice of Redenomination which requests a Redenomination of Advances into
       an Alternate Currency, such Redenomination is subject to confirmation by
       Bank not later than the third Business Day before the requested date of
       such Redenomination that such Bank agrees to such Redenomination. which
       confirmation shall be notified to the Borrowers. If no confirmation is
       provided the Redenomination will not occur. Each Advance so requested to
       be Redenominated will be Redenominated, on the date specified therefor in
       such Notice of Redenomination, into an equivalent amount thereof in the
       currency requested in such Notice of Redenomination, such equivalent
       amount to be determined on such date in accordance with Section 2.7, and,
       upon being so Redenominated, will have an initial Interest Period as
       requested in such Notice of Redenomination.

2.6.7  Prepayment:

       (i)   The Borrowers may prepay any Advance in whole or in part, at any
             time and without penalty, provided, however, that: (i) any partial
             prepayment shall first be applied, at the Bank's option, to accrued
             and unpaid interest and next to the outstanding principal balance;
             and (ii) during any period of time in which interest is accruing on
             any Advance on the basis of the Eurocurrency Rate or the Cost of
             Funds Rate, no prepayment shall be made except on a day which is
             the last day of the Interest Period pertaining thereto provided,
             however, if the whole or any part of any Fixed Rate Advance is
             prepaid by reason of acceleration or otherwise, the Borrower shall
             jointly and severally upon the Bank's request, promptly pay to and
             indemnify the Bank for all costs and any loss actually incurred by
             the Bank, excluding loss of profit on any margin, but including any
             loss resulting from the re-employment of funds, sustained by the
             Bank as a consequence of such prepayment, and provided further,
             that any prepayment hereunder shall not be deemed to be an event of
             default.

       (ii)  If, on the last day of any Interest Period, the equivalent in
             Dollars of the aggregate principal amount of all Eurocurrency
             Advances then outstanding when combined with the aggregate
             principal amount of all Variable Rate Advances and Cost of Funds
             Advances then outstanding exceeds the Acquisition Line of Credit,
             the Borrowers shall jointly and severally on such last day prepay
             an aggregate principal amount of such Advances to the Bank in an
             amount at least equal to such excess, with accrued interest to the
             date of such prepayment on the principal amount prepaid.

       (iii) The Bank shall be entitled to fund all or any portion of its
             Advances in any manner it may determine in its sole discretion, but
             all calculations and transactions hereunder shall be conducted as
             though the Bank actually funded all Advances through the purchase
             of dollar deposits bearing interest at the same rate as U.S.
             Treasury securities in the amount of the relevant Advance and in
             maturities corresponding to the date of such purchase to the
             Expiration Date hereunder.

2.6.8  Indemnification for Eurocurrency Rate and Cost of Funds Rate Costs:
       During

                                      -23-
<PAGE>

        any period of time in which interest on any Advance is accruing on the
        basis of the Eurocurrency Rate or the Cost of Funds Rate, the Borrowers
        shall jointly and severally, within 15 days of 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 requirement 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 the Alternate Currency or Dollars or cost of funds used
        by the Bank in quoting and determining the Eurocurrency Rate or the Cost
        of Funds Rate under this Agreement. Bank shall use its best efforts to
        provide Borrowers, in advance, with an estimate of any such costs which
        may potentially be incurred hereunder.

2.6.9   Eurocurrency Rate or Cost of Funds Rate Infeasible: In the event that
        the Bank shall at any time determine that the accrual of interest on the
        basis of the Eurocurrency Rate or the Cost of Funds Rate (i) is
        infeasible at the time of any borrowing, continuation or Redenomination
        because the Bank is unable to determine the Eurocurrency Rate or Cost of
        Funds Rate due to the unavailability of Dollars or Alternate Currency
        deposits, contracts or time deposits in an amount approximately equal to
        the amount of the relevant Advance and for a period of time
        approximately equal to 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
        Borrowers, in which event such Fixed Rate Advance shall be immediately
        prepaid but then may be converted or Redenominated into a Variable Rate
        Advance at the election of the Borrowers.

2.6.10  Failure to Borrow: In the case of any Fixed Rate Advance, the Borrowers
        shall jointly and severally indemnify Bank against any loss, cost or
        expense incurred by Bank as a result of any failure to borrow on the
        date specified for such Fixed Rate Advance (other than as a result of
        Bank's failure to make funds available for such Advance), including,
        without limitation, any loss (excluding loss of anticipated profits),
        cost or expense incurred by reason of the liquidation or reemployment of
        deposits or other funds acquired by Bank to fund such Fixed Rate Advance
        to be made by Bank when such Fixed Rate Advance is not made on such
        date.

2.6.11  Computations and Payments: Interest on any Advance shall be computed on
        the basis of 360 days per year, but charged on the actual number of days
        elapsed. Whenever any payment hereunder shall be stated to be due on a
        day other than a Business Day, such payment shall be made on the next
        succeeding Business Day, and such extension of time shall in such case
        be included in the computation of payment of interest; provided,
        however, if such extension would cause payment of interest on or
        principal of Eurocurrency Advances to be made in the next following
        calendar month, such payment shall be made on the immediately preceding
        Business Day.

2.6.12  Term Loan Conversion: The Borrowers may, by giving written notice to the
        Bank at any time and from time to time, convert the principal balance
        outstanding under the Acquisition Line of Credit to be payable on a term
        loan basis. The term loan (the "Acquisition Term Loan") shall be in the
        amount of such outstanding principal

                                      -24-
<PAGE>

            balance and shall be for a period of 48 months and shall be
            evidenced by a promissory note in form and substance satisfactory to
            the Bank (the "Acquisition Term Note" attached as Exhibit 2).
            Accrued and unpaid interest under the Acquisition Line of Credit
            shall be paid to the Bank concurrently with the Borrowers' execution
            of the Acquisition Term Note. In addition to the short term fixed
            rates not to exceed 12 months, the Borrower may fix the rate for the
            entire 48 month term loan at a Cost of Funds plus 1.50% or a Federal
            Funds plus 1.50%. For the Federal Funds Rate to apply a SWAP
            Agreement, which includes an ISDA Master Agreement with schedule to
            the Separate Master Agreement and a certified corporate resolution
            for such transaction, secured with a blanket lien will be required.
            Interest shall accrue and principal and interest shall be paid in
            accordance with the terms and provisions of the Term Note.

     2.6.13 Loan Fee. The Borrowers promise and agree to pay to the Bank a non-
            refundable funding fee of .25% on the acquisition facility on
            funding.

2.7  Currency Equivalents: For purposes of the provisions of this Section 2, (i)
     the equivalent in Dollars of any Alternate Currency shall be determined by
     using the quoted spot rate at which Bank's principal office in Los Angeles
     offers to exchange Dollars for such Alternate Currency at 9:00 A.M. (Los
     Angeles time) two Business Days prior to the date on which such equivalent
     is to be determined, (ii) the equivalent in any Alternate Currency of any
     other Alternate Currency shall be determined by using the quoted spot rate
     at which Bank's principal office in Los Angeles offers to exchange such
     Alternate Currency for the equivalent in Dollars of such other Alternate
     Currency at 9:00 A.M. (Los Angeles time) two Business Days prior to the
     date on which such equivalent is to be determined, and (iii) the equivalent
     in any Alternate Currency of Dollars shall be determined by using the
     quoted spot rate at which Bank's principal office in Los Angeles offers to
     exchange such Alternate Currency for Dollars at 9:00 A.M. (Los Angeles
     time) two Business Days prior to the date on which such equivalent is to be
     determined. Except as specified hereinabove, the equivalent in Dollars of
     each Eurocurrency Rate Advance made in an Alternative Currency shall be
     recalculated hereunder on each date that it shall be necessary to determine
     the unused portion of Bank's Line of Credit or any or all Advance or
     Advances outstanding on such date.

2.8  Term Loan:

     2.8.1  Term Loan: On the terms and conditions as set forth herein, the Bank
            agrees to lend to the Borrowers, in one drawing, upon the Borrowers'
            request therefore made prior to October 15, 1999, up to the maximum
            amount of $3,000,000 (the "Term Loan").

     2.8.2  Making the Term Loan. The Term Loan shall be conclusively deemed to
            have been made at the request of and for the benefit of the
            Borrowers (i) when credited to any deposit account of the Borrowers
            maintained with the Bank or (ii) when paid in accordance with
            Borrowers' written instructions.

     2.8.3  Interest. Interest on the Term Loan Balance shall accrue from the
            date of funding under the Term Loan at one of the following rates,
            as quoted by the Bank and as elected by the Borrowers pursuant to
            Subsection (i) or Subsection (ii) or Subsection (iii) below:

                                      -25-
<PAGE>

     (i)    Variable Rate Balances: A variable rate per annum equivalent to the
            ----------------------
            Reference Rate (the "Variable Rate"). Interest shall be adjusted
            concurrently with any change in the Reference Rate. A Balance based
            upon the Variable Rate is hereinafter referred to as a "Variable
            Rate Balance".

     (ii)   Fixed Rate Balances: A fixed rate per annum quoted by the Bank for
            -------------------
            30, 60, 90 or 180 days or for such other period of time that the
            Bank may quote and offer (provided that any such period of time does
            not extend beyond the Expiration Date) (the "Interest Period") for
            Balances in the minimum amount of $100,000.00. Such interest rate
            shall be a percentage approximately equivalent to the Applicable
            Margins plus the rate which the Bank determines in its sole and
            absolute discretion to be equal to the Bank's cost of acquiring
            funds (adjusted for any and all assessments, surcharges and reserve
            requirements pertaining to the borrowing or purchase by the Bank of
            such funds) 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 (the "Fixed Rate"). A Balance based upon
            the Fixed Rate are hereinafter referred to as a "Fixed Rate
            Balance".

     (iii)  LIBOR Balances: A fixed rate quoted by the Bank for one week, 1, 2,
            --------------
            3, or 6 months or for such other period of time that the Bank may
            quote and offer (provided that any such period of time does not
            extend beyond the Expiration Date) (the "LIBOR Interest Period") for
            Balances in the minimum amount of $100,000.00. Such interest rate
            shall be a percentage approximately equivalent to the Applicable
            Margin plus the Bank's LIBOR Rate which is that rate determined by
            the Bank's Treasury Desk as being the arithmetic mean (rounded
            upwards, if necessary, to the nearest whole multiple of one-
            sixteenth of one percent (1/16%)) of the U. S. dollar London
            Interbank Offered Rates for such period appearing on page 3750 (or
            such other page as may replace page 3750) of the Telerate screen at
            or about 11:00 a.m. (London time) on the second Business Day prior
            to the first days of such period (adjusted for any and all
            assessments, surcharges and reserve requirements) (the "LIBOR
            Rate"). A Balance based upon the LIBOR Rate is hereinafter referred
            to as a "LIBOR Balance".

     In addition to the interest rates already stated, Borrower may fix the rate
     for the entire 60 month term loan at a Cost of Funds plus 1.50% or a
     Federal Funds plus 1.50%. For the Federal Funds Rate to apply, a SWAP
     Agreement, including an ISDA Master Agreement with schedule to the Separate
     Master Agreement and a certified corporate resolution for such transaction,
     secured with a blanket lien, will be required. Interest shall accrue and
     principal and interest shall be paid in accordance with the terms and
     provisions of Paragraph 2.8.8 hereunder.

     Interest on any Balance shall be computed on the basis of 360 days per
     year, but charged on the actual number of days elapsed.

     Each Borrower hereby jointly and severally promises and agrees to pay
     interest on the Term Loan, in arrears, on the last calendar day of each
     month.

                                      -26-
<PAGE>

       Interest on any LIBOR Advance or Fixed Rate Advance with a LIBOR Interest
       Period or Interest Period of 3 months or less shall be paid on the last
       day of the LIBOR Interest Period or Interest Period as the case may be.
       The Borrowers further promise and agree to pay the Bank interest on any
       LIBOR Advance or Fixed Rate Advance with a LIBOR Interest Period or
       Interest Period in excess of 3 months on a quarterly basis (i.e., on the
       last day of each 3 month period occurring in such LIBOR Interest Period
       or Interest Period) and on the last day of the LIBOR Interest Period or
       Interest Period.

       If interest is not paid as and when it is due, it shall be added to the
       principal, become and be treated as a part thereof, and shall thereafter
       bear like interest.

2.8.4  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 Borrowers may elect:

       (i)    That interest on a Variable Rate Balance shall be adjusted to
              accrue at the Fixed Rate; provided, however, that such notice
              shall be received by the Bank no later than 2:00 p.m. on the
              Business Day on which the Borrowers request that interest be
              adjusted to accrue at the Fixed Rate.

       (ii)   That interest on a Variable Rate Balance shall be adjusted to
              accrue at the LIBOR Rate; provided, however, that such notice

              prior to the Business Day on which the Borrowers request that
              interest be adjusted to accrue at the LIBOR Rate.

       (iii)  That interest on a Fixed Rate Balance shall continue to accrue at

              If the Bank shall not have received notice (as prescribed herein)
              of the Borrowers' election that interest on any Fixed Rate Balance
              shall continue to accrue at the newly quoted Fixed Rate as the
              case may be the Borrowers shall be deemed to have elected that
              interest thereon shall be adjusted to accrue at the Variable Rate

          expiration of the relevant Interest Period or LIBOR Interest Period
          pertaining to such Balance.

2.8.5  Prepayment: The Borrowers may prepay any Balance in whole or in part, at
       any time and without penalty, provided, however, that: (i) any partial
       prepayment shall first be applied at the Bank's option, to accrued and
       unpaid interest and next to the outstanding principal balance; and (ii)
       during any period of time in which interest is accruing on any Balance on
       the basis of the LIBOR Rate or Fixed Rate, no prepayment shall be made
       except on a day which is the last day of the LIBOR Interest Period or
       Interest Period pertaining thereto. if the whole or any part of any LIBOR
       Balance or Fixed Rate Balance is prepaid by reason of acceleration or
       otherwise, the Borrower shall jointly and severally upon the Bank's
       request, promptly pay to and indemnify the Bank for all costs and any
       loss actually incurred by the Bank, excluding loss of profit on any
       margin, but including any loss resulting from the re-employment of funds,
       sustained by the Bank as a consequence of such prepayment, and provided
       further, that any prepayment hereunder shall not be deemed to be an event
       of default.

       The Bank shall be entitled to fund all or any portion of its Balances in
       any manner it may determine in its sole discretion, but all calculations
       and transactions hereunder shall be conducted as though the Bank actually
       funded all Advances through the purchase of dollar deposits bearing
       interest at the same rate as U.S. Treasury securities in the amount of
       the relevant Advance and in maturities corresponding to the date of such
       purchase to the Expiration Date hereunder.

2.8.6  Indemnification for LIBOR Rate or Fixed Rate Costs: During any period of
       time in which interest on any Advance is accruing on the basis of the
       LIBOR Rate or Fixed Rate, the Borrowers shall, within 15 days of the
       Bank's written request, 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 requirement 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 LIBOR
       Rate or Fixed Rate. Bank shall use its best efforts to provide Borrowers,
       in advance, with an estimate of any such costs which may potentially be
       incurred hereunder.

2.8.7  Conversion from LIBOR Rate or Fixed 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 LIBOR Rate or Fixed Rate (i) has become infeasible
       because the Bank is unable to determine the LIBOR Rate or Fixed 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
       Advance and for a period of time approximately equal to the relevant
       LIBOR Interest Period or Interest Period as the case may be or (ii) is or
       has become unlawful 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
       promptly give telephonic notice thereof (confirmed in writing) to the
       Borrowers, in which event any Advance bearing interest at either the
       LIBOR Rate or Fixed Rate as the case may be shall be deemed to be a
       Variable Rate Advance and interest shall thereupon immediately accrue at
       the Variable Rate and shall continue at such rate until the

                                      -28-
<PAGE>

            Bank determines that the LIBOR Rate or Fixed Rate is no longer
            infeasible or unlawful.

     2.8.8  Repayment. The Term Loan will amortize over 7 years but will be due
            in 5 years. The Borrowers hereby promise and agree to pay principal
            as follows: Commencing on December 1, 1999, and continuing monthly
            thereafter up to and including October 1, 2004, principal shall be
            paid monthly on the 1st of each month in 59 installments of
            $35,714.29. On November 1, 2004 of the Term Loan, the Borrowers
            hereby promise and agree to pay a balloon payment to the Bank of the
            entire unpaid principal balance, together with accrued and unpaid
            interest.

            be appropriate in connection with the credit facilities granted

            contrary within 18 months after the Borrowers' receipt of any such
            statement which it deems to be incorrect.

     2.9.2  The Borrowers hereby authorize the Bank to charge, from time to
            time, against any or all of the Borrowers' deposit accounts with the
            Bank any amount so due under this Agreement, including, but not
            limited to, account #261535176 maintained with the Bank's Rosemead
            Office (CBC).

     2.9.3  If any payment required to be made by the Borrowers hereunder become
            due and payable on a day other than a Business Day, the due date
            thereof shall be extended to the next succeeding Business Day and
            interest thereon shall be payable at the then applicable rate during
            such extension. All payments required to be made hereunder shall be
            made to the office of the Bank designated for the receipt of notices
            herein or such other office as Bank shall from time to time
            designate.

2.10 Late Payment: In addition to any other rights the Bank may have hereunder,
     if any payment of principal or interest or any portion thereof, under this
     Agreement for any of the facilities is not paid within 10 days of when due,
     a late payment charge equal to five percent (5%) of such past due payment
     may be assessed and shall be immediately payable.

                with respect thereto at the Variable Rate from the Settlement
                Date to the Close-Out Date, into US Dollars at a rate of
                exchange at which the Bank can buy or sell US dollars with or
                against the Foreign Currency for delivery on the Close-Out Date.

          (ii)  Closing Gain or Loss. (1) For a FX Transaction for which the
                Bank agreed to purchase a Foreign Currency, the amount by which
                the Closing Value exceeds the Notional Value shall be a Closing
                Loss and the amount by which the Closing Value is less than the
                Notional Value shall be a Closing Gain; and (2) For a FX
                Transaction for which the Bank agreed to sell a Foreign
                Currency, the amount by which the Closing Value exceeds the
                Notional Value shall be a Closing Gain and the amount by which
                the Closing Value is less than the Notional Value shall be a
                Closing Loss.

          (iii) Net Present Value. The Closing Gain or Closing Loss for each
                Settlement Date falling after the Close-out Date will be
                discounted by the Bank to it net present value.

          (iv)  Payment. To the extent that the net amount of the aggregate
                Closing Gains exceeds the Closing Losses, such amount shall be
                payable by the Bank to the applicable Borrower. To the extent
                that the aggregate net amount of the Closing Losses exceeds the
                Closing Gains, such amount shall be payable by such Borrower to
                the Bank.

8.7  Protection of Security Interest: Make such payments and do such acts as the
     Bank, in its sole judgment, considers necessary and reasonable to protect
     its security interest or lien in the Collateral. Each of the Borrowers
     hereby irrevocably authorizes the Bank to pay, purchase, contest or
     compromise any encumbrance, lien or claim which the Bank, in its sole
     judgment, deems to be prior or superior to its security interest. Further,
     the Borrowers hereby agree to pay to the Bank, upon demand therefor, all
     expenses and expenditures (including attorneys' fees) incurred in
     connection with the foregoing.

8.8  Foreclosure: Enforce any security interest or lien given or provided for
     under this Agreement or under any security agreement, mortgage, deed of
     trust or other document, in such manner and such order, as to all or any
     part of the properties subject to such security interest or lien, as the
     Bank, in its sole judgment, deems to be necessary or appropriate and the
     Borrowers hereby waive any and all rights, obligations or defenses now or
     hereafter established by law relating to the foregoing. In the enforcement
     of its security interest or lien, the Bank is authorized to enter upon the
     premises where any Collateral is located and take possession of the
     Collateral or any part thereof, together

                                      -41-
<PAGE>

      with the Borrower's records pertaining thereto, or the Bank may require
      any Borrower to assemble the Collateral and records pertaining thereto and
      make such Collateral and records available to the Bank at a place
      designated by the Bank. The Bank may sell the Collateral or any portions
      thereof, together with all additions, accessions and accessories thereto,
      giving only such notices and following only such procedures as are
      required by law, at either a public or private sale, or both, with or
      without having the Collateral present at the time of the sale, which sale
      shall be on such terms and conditions and conducted in such manner as the
      Bank determines in its sole judgment to be commercially reasonable. Any
      deficiency which exists after the disposition or liquidation of the
      Collateral shall be a continuing liability of the Borrowers to the Bank
      and shall be immediately paid by the Borrowers to the Bank.

8.9   Non-Exclusivity of Remedies: Exercise one or more of the Bank's rights set
      forth herein or seek such other rights or pursue such other remedies as
      may be provided by law, in equity or in any other agreement now existing
      or hereafter entered into between any of the Borrowers and the Bank, or
      otherwise.

8.10  Application of Proceeds: All amounts received by the Bank as proceeds from
      the disposition or liquidation of the Collateral shall be applied to the
      Borrowers' indebtedness to the Bank as follows: first, to the costs and
      expenses of collection, enforcement, protection and preservation of the
      Bank's lien in the Collateral, including court costs and reasonable
      attorneys' fees, whether or not suit is commenced by the Bank; next, to
      those costs and expenses incurred by the Bank in protecting, preserving,
      enforcing, collecting, liquidating, selling or disposing of the
      Collateral; next, to the payment of accrued and unpaid interest on all of
      the Obligations; next, to the payment of the outstanding principal balance
      of the Obligations; and last, to the payment of any other indebtedness
      owed by the Borrowers to the Bank. Any excess Collateral and excess
      proceeds existing after the disposition or liquidation of the Collateral
      will be returned or paid by the Bank to the Borrowers.

                                    SECTION

                                       9

                                 MISCELLANEOUS

9.1   Amounts Payable on Demand: If the Borrowers shall fail to pay on demand
      any amount so payable under this Agreement, the Bank may, at its option
      and without any obligation to do so and without waiving any default
      occasioned by the Borrowers having so failed to pay such amount, create an
      Advance under this Agreement in an amount equal to the amount so payable,
      which Advance shall thereafter bear interest as provided hereunder.

9.2   Default Interest Rate: If an Event of Default, or an event which, with
      notice or passage of time could become an Event of Default, has occurred
      or is continuing, the Borrowers shall pay to the Bank interest on any
      Indebtedness or amount payable under this Agreement at a rate which is 3%
      in excess of the rate or rates then in effect under this Agreement.

9.3   Reliance and Further Assurances: Each warranty, representation, covenant,
      obligation and agreement contained in this Agreement shall be conclusively
      presumed to have been relied upon by the Bank regardless of any
      investigation made or information possessed by the Bank and shall be
      cumulative and in addition to any other warranties, representations,

                                      -42-
<PAGE>

      covenants and agreements which any of the Borrowers now or hereafter shall
      give, or cause to be given, to the Bank. The Borrowers agree to execute
      all documents and instruments and to perform such acts as the Bank may
      reasonably deem necessary to confirm and secure to the Bank all rights and
      remedies conferred upon the Bank by this agreement and all other documents
      related thereto.

9.4   No Guaranty or Surety: If any Borrower hereunder is deemed to be a surety
      or guarantor due to its joint and several liability hereunder such
      Borrower hereby unconditionally and irrevocably acknowledges and agrees to
      the matters set forth below:

          (i)   Each Borrower waives its rights of subrogation, reimbursement,
                indemnification and contribution and any other rights and
                defenses that are or may become available to such Borrower by
                reason of Sections 2787 to 2855, inclusive, of the California
                Civil Code and as they may be amended or superseded in the
                future. Without limiting the generality of the foregoing, each
                Borrower(s) arising from the Bank's election of a remedy on any
                indebtedness under bankruptcy or other debtor relief laws or
                under any other laws, including, but not limited to those
                purporting to reduce the Bank rights against any Borrower in
                proportion to the principal obligation of any indebtedness (as
                presently contained in Section 2809 of the California Civil Code
                and as it may be amended or superseded in the future).

          (ii)  Each Borrower waives all rights and defenses that such Borrower
                may have because the Borrower's debt is secured by real
                property. This means, among other things:

                    (1)  The Bank may collect from such Borrower without first
                    foreclosing on any real property or personal property
                    collateral pledged by the Borrower(s);

                    (2)  If the Bank forecloses on any real property collateral
                    pledged by the Borrowers:

                    (i)  The amount of the debt may be reduced only by the price
                    for which that collateral is sold at the foreclosure sale,
                    even if the collateral is worth more than the sale price.

                    (ii) The Bank may collect from the Borrower(s) even if the
                    Bank, by foreclosing on such real property collateral, has
                    destroyed any right such Borrower(s) may have to collect
                    from any other Borrower(s).

This is an unconditional and irrevocable waiver of any rights and defenses the
Borrower(s) may have because the Borrowers' debt is secured by real property.
These rights and defenses include, but are not limited to, any rights or
defenses based upon Sections 580 a, 580b, 580d and 726 of the California Code of
Civil Procedure.

          (iii) Each Borrower waives all rights and defenses arising out of an
                election of remedies by the Bank, even though that election of
                remedies, such as a nonjudicial foreclosure with respect to
                security for the Borrowers' indebtedness, has destroyed such
                Borrowers' rights of subrogation and

                                      -43-
<PAGE>

       reimbursement against any other Borrower(s) by the operation of Section
       580d of the California Code of Civil Procedure or otherwise.

(iv)   Each Borrower waives any defense arising by reason of:

          (1)   The cessation from any cause whatsoever, other than payment in
          full, of the Borrowers' indebtedness;

          (2)   The application by the Borrowers of the proceeds of any Advance
          for purposes other than purposes represented by the Borrowers to the
          Bank intended or understood by the Bank or such Borrower;

          (3)   Any act or omission by the Bank which directly or indirectly
          results in or aids the discharge of the Borrowers or any Borrowers'
          indebtedness by operation of law or otherwise; or

          (4)   Any modification of the Borrowers' indebtedness, in any form
          whatsoever, including, but not limited to, any renewal, extension,
          acceleration or other change in the time for payment of such
          indebtedness or other change in the terms of such indebtedness or any
          part thereof including, but not limited to, increase or decrease of
          the rate of interest thereon.

(v)    Each Borrower waives the benefit of the statute of limitations affecting
       such Borrower's liability hereunder or the enforcement hereof.

(vi)   Each Borrower waives all right to require the Bank to: (i) proceed
       against any other Borrower(s), any endorser, cosigner, other guarantor or
       other person liable on any indebtedness; (ii) join any endorser,
       cosigner, other guarantor on any indebtedness in any action or actions
       that may be brought and prosecuted by the Bank solely and separately
       against any Borrower(s) on any indebtedness; (iii) proceed against any
       item or items of collateral securing any indebtedness or any guaranty
       thereof; (iv) give notice of the terms, time and place of any public or
       private sale of personal property held from Borrowers or any person or
       comply with Section 9504 of the California Uniform Commercial Code; or
       (v) pursue or refrain from pursuing any other remedy whatsoever in the
       Bank's power.

(vii)  Each Borrower waives any defense arising by reason of any disability or
       other defense of any other Borrower(s), successors or any endorser,
       cosigner, other guarantor or other person liable on any indebtedness.
       Until all indebtedness has been paid in full, each Borrower shall not
       have any right of subrogation and each Borrower waives any benefit of and
       right to participate in any collateral now or hereafter held by the Bank.
       Each Borrower waives all presentments, demands for performance, notices
       or nonperformance, protests, notices of protest, notices of dishonor,
       notices of sale of any collateral securing any indebtedness or any
       guaranty thereof, and notice of the existence, creation or incurring of
       new or additional indebtedness.

9.5  Communications from Borrowers; Joint and Several Liability; Extent of
     Obligations. The obligations of the Borrowers to repay the Obligations
     shall not be affected in any way or to any extent by any failure by the
     Bank to obtain direction from all the Borrowers in any given case (it being
     expressly agreed and understood that each of the Borrowers is empowered to
     act on behalf of all the Borrowers with respect to all matters relating to
     this Agreement and the credit facility evidenced hereby). The liability of
     the Borrowers hereunder is joint and several. The Borrowers hereby: (1)
     acknowledge and agree that the Bank shall have no obligation to proceed
     against any Borrower before proceeding against any other Borrower or
     Borrowers or any of the guarantors under their respective guaranties, (2)
     waive any defense to their obligations under this Agreement based upon or
     arising out of the disability or other defense or cessation of liability of
     any Borrower versus any other or of any other Person, and (3) waive any
     right of subrogation or ability to proceed against any Person or to
     participate in any security for the Obligations until the Obligations have
     been paid and reformed in full.

9.6  Attorneys' Fees: The Borrowers shall pay to the Bank all costs and
     expenses, including but not limited to reasonable attorneys fees, incurred
     by Bank in connection with the administration, enforcement, including any
     bankruptcy, appeal or the enforcement of any judgment or any refinancing or
     restructuring of this Agreement or any document, instrument or agreement
     executed with respect to, evidencing or securing the indebtedness
     hereunder.

9.7  Notices: All notices, payments, requests, information and demands which
     either party hereto may desire, or may be required to give or make to the
     other party hereto, shall be given or made to such party by hand delivery
     or through deposit in the United States mail, postage prepaid, or by
     facsimile delivery, or to such other address as may be specified from time
     to time in writing by either party to the other.

9.8  Waiver: Neither the failure nor delay by the Bank in exercising any right
     hereunder or under any document, instrument or agreement mentioned herein
     shall operate as a waiver thereof, nor shall any single or partial exercise
     of any right hereunder or under any other document, instrument or agreement
     mentioned herein preclude other or further exercise thereof or the exercise
     of any other right; nor shall any waiver of any right or default

                                      -45-
<PAGE>

      hereunder, or under any other document, instrument or agreement mentioned
      herein, constitute a waiver of any other right or default or constitute a
      waiver of any other default of the same or any other term or provision.

9.9   Conflicting Provisions: To the extent the provisions contained in this
      Agreement are inconsistent with those contained in any other document,
      instrument or agreement executed pursuant hereto, the terms and provisions
      contained herein shall control. Otherwise, such provisions shall be
      considered cumulative.

9.10  Binding Effect; Assignment: This Agreement shall be binding upon and inure
      to the benefit of the Borrowers and the Bank and their respective
      successors and assigns, except that the Borrowers shall not have the right
      to assign their rights hereunder or any interest herein without the prior
      written consent of the Bank. The Bank may sell, assign or grant
      participation in all or any portion of its rights and benefits hereunder.
      The Borrowers agree that, in connection with any such sale, grant or
      assignment, the Bank may deliver to the prospective buyer, participant or
      assignee financial statements and other relevant information relating to
      the Borrower and any guarantor.

9.11  Jurisdiction: This Agreement, any notes issued hereunder, the rights of
      the parties hereunder to and concerning the Collateral, and any documents,
      instruments or agreements mentioned or referred to herein shall be
      governed by and construed according to the laws of the State of California
      without regard to conflict of law principles, to the jurisdiction of whose
      courts the parties hereby submit.

9.12  Judgment Currency: If for the purposes of obtaining judgment in any court
      it is necessary to convert a sum due hereunder in any currency (the
      "Original Currency") into another currency (the "Other Currency") the
      parties hereto agree, to the fullest extent that they may effectively do
      so, that the rate of exchange used shall be that at which in accordance
      with normal banking procedures the Bank could purchase the Original
      Currency with the Other Currency at Los Angeles on the second Business Day
      preceding that on which final judgment is given.

      The obligation of the Borrower in respect of any sum due in the Original
      Currency from it to Bank shall, notwithstanding any judgment in any Other
      Currency, be discharged only to the extent that on the Business Day
      following receipt by Bank of any sum adjudged to be so due in such Other
      Currency Bank may in accordance with normal banking procedures purchase
      Dollars with such Other Currency; if the amount of the Original Currency
      so purchased is less than the sum originally due to the Bank, the Borrower
      agrees, as a separate obligation and notwithstanding any such judgment, to
      indemnify Bank against such loss, and if the amount of the Original
      Currency so purchased exceeds the sum originally due to Bank in the
      Original Currency, Bank agrees to remit to Borrower such excess.

9.13  Waiver of Jury Trial: EACH OF THE BORROWERS AND THE BANK WAIVE THEIR
      RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED
      UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER LOAN
      DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY
      ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE
      PARTIES AGAINST ANY OTHER PARTY OR PARTIES, WHETHER WITH RESPECT TO
      CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. EACH OF THE BORROWERS AND THE
      BANK AGREE THAT ANY



                                      -46-
<PAGE>

      SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A
      JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR
      RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION
      AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE
      OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT
      OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF. THIS
      WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
      MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

9.14  Telephone Recording: The Borrowers agree that the Bank may electronically
      record all telephone conversations between the Borrowers and the Bank
      solely with respect to any FX Transaction and that any such recording may
      be submitted in evidence in any arbitration or other legal proceeding.
      Such recording shall be deemed to be conclusive evidence as to the terms
      of any FX Transaction in the event of a dispute.

9.15  Counterparts: This Agreement may be executed in any number of counterparts
      and all such counterparts taken together shall be deemed to constitute one
      and the same instrument.

9.16  Headings:  The headings herein set forth are solely for the purpose of
      identification and have no legal significance.

9.17  Entire Agreement and Amendments: This Agreement and all documents,
      instruments and agreements mentioned herein constitute the entire and
      complete understanding of the parties with respect to the transactions
      contemplated hereunder. All previous conversations, memoranda and writings
      between the parties pertaining to the transactions contemplated hereunder
      not incorporated or referenced in this Agreement or in such documents,
      instruments and agreements are superseded hereby. This Agreement may be
