PART I ITEM 1. BUSINESS General The Company is a vertically-integrated, worldwide provider of devices, subsystems and end-products based on optoelectronic technology. The Company designs and manufactures optoelectronic devices and value-added subsystems for original equipment manufacturers ("OEMs") for use in a broad range of applications, including security, medical diagnostics, fiber optics, telecommunications, gaming, office automation, aerospace and defense electronics, 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. In the medical field, the Company manufactures and sells bone densitometers, which are used to provide bone loss measurements in the diagnosis of osteoporosis. The Company also manufactures and sells saturation of arterial hemoglobin ("SpO\\2\\") monitors and sensors under the trade names Digital Dolphin(TM) and Dolphin 2000(TM). Digital Dolphin(TM) model 2100 SpO\\2\\ monitors have received 510[k] approval for sale in the United States. In fiscal 2001, revenues from the sale of optoelectronic devices and subsystems and medical imaging systems amounted to $59.3 million, or approximately 53.4% of the Company's revenues, while revenues from sales of security and inspection products amounted to $51.8 million, or approximately 46.6% of the Company's revenues. Further information concerning market segments is available in Note 14 to the Company's financial statements, at page F-25. 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 devices and subsystems are designed and manufactured primarily for sale to OEMs, while the Company's security products and medical imaging and some monitoring systems are sold to end-users. Optoelectronic 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. Optoelectronic devices also are key components in the telecommunications and fiber optics market. 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. 1

Through a wholly-owned subsidiary, RapiTec, Inc., the Company has penetrated the worldwide weapons simulation market through system engineering, product development, rapid prototyping, and volume manufacturing for state-of- the-art, laser-based training systems for the defense industry. The Company has developed high-speed silicon photodiodes for use in fiber optic systems such as Gigabit Ethernet and Fiber Channel systems. These products can replace Gallium Arsenide products at about half the cost. The Company has developed a silicon-based fiber optic detector which can achieve a 2.5 Gigabit/second data rate using 3.3 volts bias voltage. Through a wholly- owned subsidiary, OSI Fibercomm, Inc., the Company has launched a new family of Indium Gallium Arsenide photodetectors for use in a variety of network applications and long-haul communications applications, together with high- speed silicon-based detectors combined with transimpedence amplifiers ("TIA"). Medical Diagnostic and Imaging Systems. The Company has expanded into medical diagnostic and imaging systems. The Company manufactures and distributes the DTX 200 (DEXACARE), a 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 ultrasound scanner using imaging capability for the diagnosis of osteoporosis. In September, 2000, the Company received pre-market approval ("PMA") from the FDA to sell the DTU-One in the United States. The Company also acquired majority ownership of TFT Medical, Inc., which has been renamed "OSI Medical, Inc." ("OSI Medical"), which is currently developing new-generation pulse oximeter instruments and probes for use in the medical field. The Company also has five-year warrants (subject to earlier termination upon the occurrence of certain events) to acquire up to 1,110,000 additional OSI Medical shares at a purchase price of $1.35 per share. The warrants first became exercisable on April 12, 2001. In August 2000, the Company acquired all the assets of Square One Inc., which develops and manufactures infrared-based patient monitoring medical subsystems. The Company presently manufactures a number of medical devices through several of its subsidiaries, some of which are described above, and has recently formed a new subsidiary, Dolphin Medical, Inc., for the purpose of consolidating its various medical devices into a single subsidiary. 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 explosives. In July 1996, President Clinton formed the White House Commission 2

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 U.S. government is continuing to fund procurement of 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. The recent terrorist attacks on the World Trade Center and the Pentagon using hijacked airliners likely will cause a substantial increase in airport security measures, which may result in an increase in sales of the Company's security and inspection products. In April 2000, the Company was awarded a contract by the Federal Aviation Administration ("FAA") to provide x-ray screening systems at selected airports throughout the United States. Under the contract, the FAA has the right to purchase up to 800 systems, for which the purchase price would be approximately $40 million. The initial purchase under the contract was for approximately 100 carry-on baggage x-ray screening systems, all of which were shipped in fiscal 2001. The FAA ordered more than 200 additional systems during fiscal 2001, some of which were shipped in fiscal 2001, and the balance of which will be shipped in fiscal 2002. 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 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 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 1987, the Company formed Opto Sensors (Singapore) PTE Ltd. ("OSI Singapore") to manufacture optoelectronic devices and subsystems. 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. 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, in August 1999 the Company decided to close the operations of Osteometer in Denmark, and relocate certain of these operations to the Company's U.S. facilities. In the quarter ended September 30, 1999, the Company recorded estimated restructuring costs of $1.9 million related to the closure of the Osteometer facility in Denmark. These costs were 3

associated primarily with the termination of certain employees, commitments and other facility closure costs. During the quarter ended March 31, 2000, the Company completed the closure of the Osteometer facility in Denmark and the relocation of the operations to the United States. The market for osteoporosis diagnostic equipment 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 $739,000), in lieu of contingent payments of up to $1.5 million, based on future sales. The acquisition of Metorex Security brought 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. On March 31, 2001, the Company sold all of the outstanding stock of SMI to Elmos Semiconductor AG of Germany for $6 million in cash. In connection with this transaction, the Company's UDT subsidiary sold certain capital equipment to SMI for $462,000 in cash. The sale also includes a three-year commitment from UDT to supply four-inch silicon foundry wafers to SMI and to dedicate limited manufacturing facilities to be used by SMI for its etching operations. The total pre-tax gain on the transaction was approximately $3 million. 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%, and in August 2000, the Company acquired substantially all of its assets for consideration of $259,000 in cash, including professional fees associated with the acquisition, future royalties (on which a $30,000 advance payment was made), and return of the Square One stock held by the Company. The acquired business develops and manufactures infrared-based patient monitoring medical subsystems. During fiscal 1999, the Company invested $1.0 million, including professional fees associated with the acquisition, in OSI Medical for an equity share of approximately 40%. OSI Medical develops new generation pulse oximeter instruments and probes for use in the medical field. Pursuant to an agreement entered into as of October 4, 1999 (the "OSI Medical Agreement") the Company acquired an additional equity interest, representing approximately 16% of the stock ownership of OSI Medical for $1.2 million, including professional fees associated with the acquisition. During Fiscal 2001, the Company acquired additional equity interest representing approximately 19% of the ownership of OSI Medical for $282,000. With these additional equity investments, the Company increased its equity share in OSI Medical to approximately 75%. On April 12, 2000, also pursuant to the OSI Medical Agreement and in connection with certain amounts loaned or to be loaned by the Company to OSI Medical thereunder, the Company also acquired five-year warrants (subject to earlier termination upon the occurrence of certain events) to acquire up to 1,110,000 additional OSI Medical shares at a purchase price of $1.35 per share. The warrants, if fully exercised, would result in the Company's share in OSI Medical being increased to over 78%, based upon the number of shares presently outstanding. Also, pursuant 4

to the OSI Medical Agreement, the Company has an option, which expires in December 31, 2002, to acquire all of OSI Medical. The Company intends to continue to build its 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 by attracting new customers. The Company presently manufactures a number of medical devices through several of its subsidiaries, some of which are described above, and has recently formed a new subsidiary, Dolphin Medical, Inc., for the purpose of consolidating its various medical devices in a single subsidiary. The Company has developed high-speed silicon photodiodes for use in fiber optic systems such as Gigabit Ethernet and Fiber Channel systems. These products can replace Gallium Arsenide products at about half the cost. The Company has developed a silicon-based fiber optic detector which can achieve a 2.5 Gigabit/second data rate using 3.3 volts bias voltage. Through a wholly- owned subsidiary, OSI Fibercomm, Inc., the Company has launched a new family of Indium Gallium Arsenide photodetectors for use in a variety of network applications and long-haul communications applications, together with light speed silicon-based detectors combined with transimpedence amplifiers ("TIA"). Further Penetrate Existing Security and Inspection Markets and Expand into Other Markets. During the fiscal year ended June 30, 2001, 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 the 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. 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 5

new sources of manufacturing and sales capabilities to maintain and enhance the benefits of its international presence. Selectively Enter New End Markets. Similar to the Company's expansion during fiscal 1998 into optoelectronic products for medical diagnostic applications, the Company intends to selectively enter new end markets that complement its existing capabilities in designing, developing and manufacturing optoelectronic devices and subsystems. The Company believes that by manufacturing other end products which rely on the technological 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 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 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. The devices manufactured by the Company are both standard products and products customized for specific applications. Most of the devices manufactured are incorporated into the subsystems manufactured by the Company. In addition to the manufacture of standard and OEM products, 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: fiber optics, 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 drives, and detection subsystems for submarines. The Company has also started manufacturing and shipping high-speed silicon based photodetectors and detector-amplifier hybrids serving the fiber-optics and telecommunications market for LAN, 1.25 Gbps and 2.5 Gbps applications. In addition to Silicon , the company has started shipping Indium Gallium Arsenide photodetectors serving a wide variety of storage, local, metropolitan and wide area networks (LAN, MAN, WAN) and other long haul telecommunications marketplace. Through the acquisition of majority-owned subsidiary OSI Medical, Inc., the Company has also expanded into the field of manufacturing and selling digital medical monitoring systems. In this field, the Company offers families of pulse oximetry sensors to end users based on analog and digital signal processing technology. 6

The Company has also moved into the field of manufacturing and selling the DTX 200 (DEXACARE) a U.S. Food & Drug Administration ("FDA")-approved forearm DEXA (Dual Energy X-Ray) densitometer, which is used in the diagnosis of 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. In September, 2000, the Company received pre-market approval ("PMA") from the FDA to sell the DTU-One in the United States. 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 1999, 2000 and 2001, approximately 20.5%, 26.1% and 28.3%, 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 Company's products 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. With the acquisition of Metorex Security, the Company acquired walk-through metal detection systems which utilize pulse induced magnetic fields combined with microprocessor based electronics, which provide uniform detection of ferrous and non-ferrous metallic objects. The technologies range from dual channel crossed magnetic fields to multi-zone coil configuration. 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 personal scanning. 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. In April 2000, the Company was awarded a contract by the Federal Aviation Administration ("FAA") to provide x-ray screening systems at selected airports throughout the United States. Under the contract, the FAA has the right to purchase up to 800 systems, for which the purchase price would be approximately $40 million. The 7

initial purchase under the contract was for approximately 100 carry-on baggage x-ray screening systems, all of which were shipped in fiscal 2001. The FAA ordered over 200 additional systems during fiscal 2001, some of which were shipped in fiscal 2001, and the balance of which will be shipped in fiscal 2002. The following table sets forth certain information related to the standard security and inspection products currently offered by the Company. The Company does, however, also customize its standard products to suit specific applications and customer requirements: SELECTED MODEL (Technology) APPLICATIONS INSTALLATIONS ----------------------- ---------------------------------- ------------------------------ Rapiscan 519 Inspection of incoming package Embassies Post offices Courthouses High risk office buildings Manufacturing companies Rapiscan 500 Series Airport hand carried and checked -Standard Tunnel baggage Airports (single view Pallet inspection Prisons and dual view 160 kV Customs inspections Government buildings x-ray Agriculture inspection Nuclear facilities source, single energy Cruise ships and dual Freight shippers energy) Border crossings Rapiscan 500 Series Large pallet inspection -Large Tunnel (single Customs inspections view and Airports dual view 320-450 kV Freight shippers x-ray Border crossings source) High risk seaport locations Rapiscan 500 Series Mobile x-ray inspection -Mobile Systems (x-ray Conventions and special events van or Airports Customs inspections trailer) Border crossings Rapiscan Series 2000 Fixed Site Cargo Inspection Cargo Systems Freight Shippers Inspection Systems Border Crossings Metor 100 Series Walk-through metal detection Airports Courthouses Government buildings Conventions and special events Metor 200 Series Multi-zone walk-through metal Airports detection Prisons Nuclear facilities Government buildings Courthouses SECURE 1000 (non- High Security Personnel Inspection Prisons intrusive Military Facilities personal screening Border crossings system) Customs Threat Image Projection Performance Monitoring Majority of Rapiscan ("TIP") 500 Series Systems 8

Markets, Customers and Applications Optoelectronic Devices and Subsystems. The Company's optoelectronic devices and subsystems are used in a broad range of products by a variety of customers. The following table illustrates, for the year ended June 30, 2001: (i) the major product categories for which the Company provided optoelectronic products; and (ii) certain representative customers in each such category. The Company expects that the list of product categories, the amount of business derived from each such product category, and the composition of its major customers will vary from period to period. Representative Major Product Category Customers ------------------------------------------------------ ----------------------- Computed Tomography and X-Ray Imaging Marconi Medical Systems Siemans Medical InVision Technologies Aerospace and Avionics Cubic Defense Systems Allied Signal Honeywell Avionics Litton Systems Medical Monitoring Datascope BCI Invivo Research Analytical, Medical Diagnostics and Particle Analyzers Abaxis Coulter Corporation Office Automation and Computer Peripherals Lexmark Xerox Eastman Kodak Construction and Industrial Automation Spectra Physics Dr. Johannes Heidenhain Baumer Electric Military/Defense and Weapons Simulations Lockheed Martin (Loral) Raytheon Norsk Forsvarstekmol Bar Code Scanners Symbol Technologies Mettrologic Instruments Gaming Industry Bally Gaming Fiber Optics/Telecommunications JDS Uniphase Nortel In August 2000, the Company formed OSI Fibercomm, Inc., a wholly-owned subsidiary, to advance the Company's fiber optic business. Fibercomm has undertaken the sales and marketing of the Company's Indium Gallium Arsenide and silicon photodetectors and other fiber optic products developed by the Company's subsidiary UDT Sensors, Inc. 9

Security and Inspection Products. Since entering the security and inspection products market in 1993, the Company has shipped approximately 5,500 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: Overseas Domestic -------------------------------------- ------------------------------------ Prague Airport, Czech Republic Major U.S. Airlines Gatwick Airport, England Bush Intercontinental Airport Heathrow Airport, England Federal Courthouses TNT Freight, England Federal Reserve Bank Japanese Embassies, worldwide JFK International Airport Malaysian Airport Board, Malaysia Los Angeles County Courthouse HAJ Terminal, Saudi Arabia Los Angeles International Airport Dubai Airport, U.A.E. Miami Airport United Kingdom Prison System, United Kingdom Orlando Airport INFRAERO, airports, Brazil Ronald Reagan National Airport Chek Lap Kok International Airport, Hong Kong U.S. Government Pudong Shanghai International Airport, P.R. China California Department of Corrections Kremlin, Russia U.S. Department of Corrections New Zealand Customs, New Zealand Empire State Building Vatican World Trade Center 2000 Summer Olympics, Sydney, Australia Narita Airport, Tokyo The market for most security and inspection products developed in response to civilian airline highjackings. Consequently, 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. The recent terrorist attacks on the World Trade Center and the Pentagon using hijacked airliners likely will cause an increase in airport security measures, which may result in an increase in sales of the Company's security and inspection products. In September 1998, the Company entered into an agreement with the Federal Aviation Administration for advanced contraband detection systems with 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. Systems were shipped during fiscal 2000 and 2001 and continue to be shipped during fiscal 2002. 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. has supplied, installed and will continue to maintain approximately 150 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. 10

During fiscal 2001, 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 April 2000, the Company was awarded a contract by the Federal Aviation Administration ("FAA") to provide x-ray screening systems at selected airports throughout the United States. Under the contract, the FAA has the right to purchase up to 800 systems, for which the purchase price would be approximately $40 million. The initial purchase under the contract was for approximately 100 carry-on baggage x-ray screening systems, all of which were shipped in fiscal 2001. The FAA ordered over 200 additional systems during fiscal 2001, some of which were shipped in fiscal 2001, and the balance of which will be shipped in fiscal 2002. In June 2000, the Company was awarded a contract to supply two Rapiscan 2000 Series Large Vehicle Cargo X-ray Systems to the government of Hong Kong. The aggregate price of these systems as of June 30, 20001 is approximately $9.6 million, an increase of $600,000 over the original project price, due to optional system upgrades. Marketing, Sales and Service The Company markets and sells its optoelectronic 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 40 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 seven independent sales representatives. The Company markets and sells its security and inspection products worldwide through a direct sales and marketing staff of approximately 30 employees located in the United States, Finland, Canada, the United Kingdom, Dubai, and Malaysia and through a network of approximately 135 independent sales representatives. The Company's optoelectronic products and medical imaging systems sales staff, located in the United States 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 45 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 1999, 2000 and 2001, maintenance service revenues and replacement part sales collectively represented 3.6%, 3.6% and 3.5%, 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 Hawthorne, California, and 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 11

components or subsystems are not available from other manufacturers of optoelectronic 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, 2001, in addition to the engineers that the Company employed in manufacturing, process design and applications development, the Company engaged approximately 95 full-time engineers and technicians in research and development. During fiscal 2001 and 2000, the Company's research and development expenses were approximately $6.7 million and $7.7 million, respectively. The decrease was primarily due to certain research and development personnel working on specific shipments and the cost of their services was charged to manufacturing overhead. 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 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, Singapore, Malaysia, Finland, Canada and Norway, in addition to its manufacturing facilities in Hawthorne, California and Ocean Springs, Mississippi. 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 facility 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 12

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 June 1999, as part of the settlement of an arbitration, the Company entered into a fully paid-up, nonexclusive patent license agreement with PerkinElmer, Inc., formerly known as EG&G, Inc. ("EG&G") for U.S. Patent No. 4,366,382. The patent expired in September 2000. Subsequent to the end of the patent term, the Company has been free to use the technology without patent or license restriction. Under the license, for which the Company paid $450,000, the Company was 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. 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. In July 2000, Rapiscan was awarded U.S. Patent No. 6,094,472 for an X-ray Backscatter Imaging System relating to improvement of the SECURE(TM) product line. This patent expires in 2018. 13

Rapiscan Security Products utilize the trademarks Rapiscan(R) and SECURE(TM). UDT has a patent application pending for high-speed (greater than 1.0Gbps) silicon photodiode for fiber optics market; it is unknown at this time if this patent 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. 4,605,898; 5,121,105; 5,047,718; 4,894,619) 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. Osteometer owns U.S. Patent No. 6,058,157, expiring 2018, for new region of interest for monitoring medical treatment for osteoporosis, and U.S. Patent No. 6,086,538, expiring 2018, for placement of the region of interest based on an anatomical feature in the calcaneus for ultrasound technology. The following are additional patents held by the Company through its subsidiaries. The dates specified are the filing dates; patents generally expire 20 years after the filing date. Patents subject to the University of South Florida License: 5,575,284 Portable Pulse Oximeter; April 1, 1994 5,830,137 Green Light Pulse Oximeter; November 18, 1996 Medical Diagnostic Instrument using Light to Frequency Converter; 6,011,985 November 18, 1996 Patents acquired in the medical field: D384,412 Rectal Probe; October 20, 1995 D387,862 Anatomical Probe Attachment; October 20, 1995 5,217,012 Non-Invasive Oximeter Probe; August 22, 1991 5,329,922 Oximetric Esophageal Probe; October 19, 1992 5,368,025 Non-Invasive Oximeter Probe; March 25, 1993 5,417,207 Apparatus for the Invasive use of Oximeter Probes; December 6, 1993 5,429,129 Apparatus for Determining Spectral Absorption by a Specific Substance in a Fluid; November 8, 1993 5,715,816 Improved Oximeter Probe; October 20, 1995 5,067,492 Disposable Airway Adapter; August 7, 1990 5,081,998 Optically Stabilized Infrared Energy Detector; May 11. 1990 5,095,913 Shutterless Optically Stabilized Capnograph; May 11, 1990 5,247,185 Regulated Infrared Source; October 28, 1991 D342,135 Airway Adapter; October 28, 1991 5,281,817 Method of Selecting an Optical Filter for a Shutterless Optically Stabilized Capnograph.; October 28,1991 5,282,473 Sidestream Infrared Gas Analyzer Requiring Small Sample Volumes; November 10, 1992 5,296,706 Shutterless mainstream discriminating anesthetic agent analyzer ; December 2, 1992 5,932,877 High performance side stream infrared gas analyzer; April 17, 1997 6,091,504 Method and apparatus for measuring gas concentration using a semiconductor laser; May 21, 1998 6,095,986 Disposable anti-fog airway adapter; July 28, 1998 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. 14

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 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 material 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. The Company has recently discovered soil and groundwater contamination at its Hawthorne, California facility. It has filed the requisite reports concerning this problem with the appropriate environmental authorities. The Company has not yet received any response to such reports, and no agency action or litigation is presently pending or threatened. The Company also has notified the prior owners of the Company property and the present owners and tenants of adjacent properties concerning the problem and has requested from such parties agreements to toll of the statute of limitations with respect to actions against such parties with respect to the contamination in order that it may focus its attention on resolution of the contamination problem. The Company site has been used previously for semiconductor manufacturing similar to that presently conducted on the site by the Company, and it is not presently known who is responsible for the contamination and the remediation. The groundwater contamination is a known regional problem, not limited to the Company premises or its immediate surroundings. 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 devices and subsystems and medical imaging systems market or the security and inspection markets or that future competitive pressures will not materially and adversely affect its business, financial conditions and results of operations. In the optoelectronic 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 PerkinElmer, Inc.'s Electro-Optics division, 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 15

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 fiber optics market, the Company has many competitors, both domestic and foreign. 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 the Astrophysics and Vivid Technologies divisions of PerkinElmer, Inc., Heimann Systems GmbH, InVision Technologies, Inc., American Science and Engineering, Inc., Barringer Technologies, Inc., Control Screening L.L.C., CEIA, SpA, Garrett Electronics, Inc. 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 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. Additionally, the Company's true multi-zone technology provides the ability to detect small metallic objects and offer higher levels of discrimination in weapons-screening applications. 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 devices and subsystems, and medical imaging systems as well as its security and inspection products within one to several 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 may require several months to several years 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, among others: (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. At June 30, 2001, the Company's backlog products totaled approximately $53.2 million, compared to approximately $54.3 million at June 30, 2000 and approximately $44.1 million at June 30, 1999. The backlogs at June 30, 2000 and 1999 include backlogs of SMI of approximately $4.5 million and $4.6 million, respectively, whereas the June 30, 2001 backlog does not include any SMI backlog because the Company has sold SMI. The backlog as of June 30, 2001, includes approximately $6 million of OSI Fibercomm backlog, delivery of most of which is presently on hold and being rescheduled with customers, and the Company does not presently know when it may be shipped. Most of the Company's backlog as of June 30, 2001, with the exception of a majority of an order for large cargo-scanning machines valued at approximately $7 million, is expected to be shipped during the fiscal year ending June 30, 2002. Any failure of the Company to meet an agreed upon schedule could 16

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, 2001, the Company employed approximately 965 people, of whom 690 were employed in manufacturing, 95 were employed in research and development, 75 were employed in finance and administration, 60 were employed in sales and marketing, and 45 were employed in its service organization. Of the total employees, approximately 492 were employed in the United States, 4 in Canada, 143 were employed in Europe, and 326 were employed in Asia. Other than 16 employees of AME and 10 Metorex Security employees in Finland, none of the Company's other employees is unionized. 16 employees at AME and 10 Metorex Security employees in Finland are union members and have collective bargaining rights. There has never been a work stoppage or strike at the Company, and management believes that its relations with its employees are good. ITEM 2. PROPERTIES The Company owns three buildings (approximately 88,000 square feet) which comprise its principal facility in Hawthorne, California. This facility is used for manufacturing, engineering, sales and marketing. As of June 30, 2001, the Company leased all of its other facilities, as reflected in the following table: Approximate Lease Location Description of Facility Square Footage Expiration -------- ----------------------- -------------- ---------- Hawthorne, California Manufacturing, 41,600 2006 engineering, sales and marketing and service Walnut, California Manufacturing, 6,350 2003 engineering, sales and marketing Ocean Springs, Mississippi Manufacturing, 41,800 2001 engineering and sales and marketing Princeton, New Jersey Service and sales and 2,900 2001 marketing Georgetown, Canada Manufacturing, 2,200 Month-to- engineering, sales and month marketing and service Johor Bahru, Malaysia Manufacturing, sales and 80,000 2003 service Singapore, Republic of Singapore Manufacturing, sales and 3,000 2003 materials procurement Crawley, United Kingdom Manufacturing, 18,700 2011 engineering, sales and marketing Hayes, United Kingdom Service 3,900 2003 Horten, Norway Manufacturing, 19,800 2008 engineering, sales and marketing Espoo, Finland Manufacturing, 18,500 2006 engineering, sales and marketing The lease of the 41,800 square foot facility at Ocean Springs, Mississippi expired in August 2001. The Company is presently negotiating the renew of the lease. It expects it will be renewed on similar terms, but if not the Company may move to a new facility. 17

The lease of the 2,900 square foot facility at Princeton, New Jersey expires in December 2001. The Company is presently negotiating the renew of the lease and expects it will be renewed on similar terms. 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. On March 30, 2000, Gail Marie Harrington-Wisely and Joyce Garland filed a class action suit, case number BC 227373, in the Superior Court of California, County of Los Angeles, naming Rapiscan Security Products, a subsidiary of the Company, and others as defendants. The named plaintiffs are the wives of men incarcerated in California prisons. The plaintiffs allege that while attempting to visit their husbands in prison, as a condition to such visits, prison personnel have subjected them, and other members of the putative class, to scans by the Company's Secure 1000, strip searches, and body cavity searches, all of which plaintiffs allege to have been illegal searches and have caused them emotional injuries. The other defendants in the action include the State of California, the California Department of Corrections, its Director and other Department of Corrections personnel. The complaint, which has been amended three times since it was filed, in essence, asserts that these types of searches are illegal and intrusive and have caused emotional injury to the plaintiffs. In addition to alleging the Company is somehow responsible for illegal searches conducted by prison personnel, with respect to Rapiscan Security Products, the complaint alleges that the Company was negligent because it knew or should have known that the Secure 1000 would be used by prison personnel to conduct illegal searches of prison visitors, that the Secure 1000 is defective in design and manufacture because of alleged inconsistent and false-positive results, that the Company has failed to properly train the prison personnel using the Secure 1000 as to how to interpret the scans, and that the Company has failed to warn subjects that they might be subjected to illegal searches using the Secure 1000 and that the scans are more intrusive than frisk searches. Plaintiffs have prayed for general, special and punitive damages in unspecified amounts and declaratory relief against illegal searches. We believe that these claims against the Company have no merit and we intend to vigorously defend this suit. However, due to the inherent uncertainties of all litigation, we can make no prediction about the outcome of this litigation.

All forward- looking statements contained in this Annual Report on Form 10-K are qualified in their entirety by this statement. Overview The Company is a vertically integrated worldwide provider of devices, subsystems and end-products based on optoelectronic technology. The Company designs and manufactures optoelectronic 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 21

manufacture and sale of bone densitometers, which are used to provide bone loss measurements in the diagnosis of osteoporosis. In fiscal 2001, revenues from the sale of optoelectronic devices and subsystems and medical imaging systems amounted to $59.3 million, or approximately 53.4% of the Company's revenues, while revenues from sales of security and inspection products amounted to $51.8 million, or approximately 46.6% 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 OSI Singapore to manufacture optoelectronic devices and subsystems. In April 1990, the Company acquired UDT Senors' 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, during the quarter ended March 31, 2000, the Company closed Osteometer's manufacturing facilities in Denmark and relocated the facilities to the United States. 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 2000, the Company acquired substantially all of the assets of Square One Technology for total consideration consisting of: $259,000 in cash, including professional fees associated with the acquisition, a $30,000 advance for future royalties, the return of Square One stock held by the Company with a carrying value of $259,000, and an agreement to pay royalties equal to 10% of net sales of the Square One products in the next five years, up to a maximum of $1,000,000. The business so acquired develops and manufactures infrared-based patient monitoring medical subsystems. During fiscal 1999, the Company invested $1.0 million including professional fees associated with the acquisition, in OSI Medical for an equity share of approximately 40%. OSI Medical develops new generation pulse oximeter instruments and probes for use in the medical field. Pursuant to an agreement entered into as of October 4, 1999 (the "OSI Medical Agreement") the Company acquired an additional equity interest, representing approximately 16% of the stock ownership of OSI Medical for $1.2 million, including professional fees associated with the acquisition. During fiscal 2001, the Company acquired an additional equity interest representing approximately 19% of the ownership of OSI Medical for $282,000. With these additional equity investments, the Company increased its equity share in OSI Medical to approximately 75%. On April 12, 2000, also pursuant to the OSI Medical Agreement and in connection with certain amounts loaned or to be loaned by the Company to OSI Medical thereunder, the Company also acquired five-year warrants (subject to earlier termination upon the occurrence of certain events) to acquire up to 1,110,000 additional OSI Medical shares at a purchase price of $1.35 per share. The warrants became exercisable commencing on April 12, 2001, and, if fully exercised, would result in the Company's share in OSI Medical being increased to over 78%, based upon the number of shares presently outstanding. Also, pursuant to the OSI Medical Agreement, the Company has an option, which expires in December 31, 2002, to acquire all of OSI Medical. 22

To broaden its product base, in fiscal 1999, the Company acquired SMI. On March 31, 2001 the Company sold all of the outstanding stock of SMI to Elmos Semiconductor AG of Germany for $6.0 million in cash. In connection with the transaction, UDT sold certain capital equipment to SMI for $462,000 in cash. The sale agreement also includes a three year commitment from UDT to supply four inch silicon foundry wafers to SMI and to dedicate limited manufacturing facilities to be used by SMI, for its etching operations. The total pre-tax gain on this transaction was $3.0 million. Also, in fiscal 1999, the Company purchased Metorex Security. The acquisition of Metorex Security brought 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. The Company engages in significant international operations. The Company currently manufactures its optoelectronic devices and subsystems, and medical imaging systems, at its facilities in Hawthorne, California, Ocean Springs, Mississippi, Singapore, Johor Bahru, Malaysia; and Horten, Norway. 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, 2001, the Company marketed its products worldwide through approximately 60 sales and marketing employees located in seven countries, and through approximately 175 independent sales representatives. Revenues from shipments made outside of the United States accounted for 48.5%, 55.8% and 43.2 % of revenues for the fiscal years 1999, 2000 and 2001 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 14 in the Company's Consolidated Financial Statements. The effective income tax rate of the Company has varied because of a mix of income from U.S. and foreign operations and utilization of previously unrealized net operating losses, and will continue to vary in the future. 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. The recent terrorist attacks on the World Trade Center and the Pentagon using hijacked airliners likely will cause a substantial increase in airport security measures, which may result in an increase in sales of the Company's security and inspection products. In April 2000, the Company was awarded a contract by the Federal Aviation Administration ("FAA") to provide x-ray screening systems at selected airports throughout the United States. Under the contract, the FAA has the right to purchase up to 800 systems, for which the purchase price would be approximately $40 million. The initial purchase under the contract was for approximately 100 carry-on baggage x-ray screening systems, all of which were shipped in fiscal 2001. The FAA ordered over 200 additional systems during fiscal 2001, some of which were shipped in fiscal 2001, and the balance of which will be shipped in fiscal 2002. 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 and to outside parties. Because of 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. The market for fiber optic products is weak at present and likely will remain weak for the foreseeable future. The Company's fiber optics product subsidiary, OSI Fibercomm, had a backlog of approximately $6 million as of June 30, 2001, but the production and delivery of such backlog is presently on hold and being rescheduled with customers, and the Company does not presently know when it may be shipped. The Company recognizes revenues upon shipment. In addition, the Company has undertaken projects which include the development and construction of significantly larger complex systems under contracts extending over 23

longer periods, such as complex cargo inspection products. Accordingly, the Company has adopted the percentage of completion method of revenue recognition for these products only. Results of Operations The following table sets forth certain income and expenditure items as a percentage of total revenues for the periods indicated. Year Ended June 30, ---------------------- 1999 2000 2001 ------ ------ ------ Revenues.............................................. 100.0% 100.0% 100.0% Cost of goods sold.................................... 71.4 72.7 72.8 ------ ------ ------ Gross profit.......................................... 28.6 27.3 27.2 Operating Expenses: Selling, general and administrative................. 17.4 17.9 19.4 Research and development............................ 5.6 6.9 6.0 Good will amortization.............................. 0.6 0.5 0.4 Asset impairment charge............................. 3.9 -- -- In process research and development................. 2.5 -- -- Restructuring Costs................................. 0.5 1.7 -- ------ ------ ------ Total operating expenses.......................... 30.5 27.0 25.8 (Loss) income from operations.........................

Revenues consist of sales of optoelectronic devices, subsystems and medical imaging systems as well as security and inspection products. Revenues are recorded net of intercompany eliminations. Revenues for the fiscal year ended June 30, 2001, increased by $161,000, or 0.1%, to $111.1 million from $110.9 million for the fiscal year ended June 30, 2000. Revenues for the sale of optoelectronics devices, subsystems and medical imaging systems, net of intercompany eliminations, decreased by $4.5 million, or 7.1%, to $59.3 million from $63.8 million for fiscal 2000. The decrease was primarily due to decreased sales of the discontinued product line of data/video projector systems, and was partially offset by increased sales of fiber optics and sales to the weapon simulation market. Sales of the discontinued product line of data/video projector systems for the fiscal 2001 and 2000 were $1.0 million and $10.9 million, respectively. The Company expects that the fiber optics market will be weak in the foreseeable future. Revenues from the sale of security and inspection products increased $4.7 million, or 9.9% to $51.8 million from $47.1 million for fiscal 2000. The increase was primarily due to increased shipments of x-ray screening systems for selected airports throughout the United States under a Federal Aviation Administration (FAA) contract and revenue recognized under new large vehicle cargo x-ray systems contracts. 24

Gross Profit. Cost of goods sold consist of material, labor and manufacturing overhead. Gross profit decreased by $92,000, or 0.3%, to $30.2 million from $30.3 million for fiscal 2000. As a percent of revenues, gross profit decreased to 27.2% in fiscal 2001 from 27.3% in fiscal 2000. The decrease in gross margin was due to a change in product mix and certain research and development personnel working directly on specific shipments. Selling, General and Administration. 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, 2001, such expenses increased by $1.7 million or 8.8% to $21.6 million from $19.8 million in fiscal 2000. As a percentage of revenues, selling, general and administrative expenses increased to 19.4% in fiscal 2001 from 17.9% in fiscal 2000. The increase in expenses was primarily due to increased administrative expenses, legal and professional fees and an increase in provision for doubtful receivables, offset in part by proceeds of $409,000 from settlement of certain litigation. Research and Development. Research and development expenses include research related to new product development and product enhancement expenditures. For the year ended June 30, 2001, such expenses decreased by $1.0 million, or 13.5% to $6.7 million from $7.7 million in fiscal 2000. As a percentage of revenues, research and development expenses decreased to 6.0% in fiscal 2001 from 6.9% in fiscal 2000. The decrease in expenses was primarily due to certain research and development personnel worked directly on specific products and the cost of their services was charged to manufacturing overhead, offset in part by increased research and development spending for medical and fiber optics products. Goodwill Amortization. Amortization of goodwill decreased to $488,000 in fiscal 2001 from $529,000 in fiscal 2001. The decrease in amortization of goodwill was primarily due to reduction of goodwill associated with the disposition of SMI for part of the year. Income from Operations. For the year ended June 30, 2001, income from operations was $1.5 million compared to $373,000 for fiscal 2000. Excluding the non-recurring restructuring costs of $1.9 million in fiscal 2000, income from operations decreased to $1.5 for the year ended June 30, 2001, compared to $2.3 million in fiscal 2000. Income from operations decreased primarily due to increased selling, general and administrative expenses and was offset in part by decreased research and development expenses. Gain on Sale of Subsidiary. On March 31, 2001, the Company sold all of the outstanding stock of its wholly owned subsidiary SMI to ELMOS Semiconductor AG of Germany for $6.0 million in cash resulting in a gain of $3.0 million. In addition, as a part of the agreement, $2.2 million of the accounts payable by SMI to the Company as a result of intercompany transactions was converted to a note receivable from the buyer over a period of four and a half years. As of June 30, 2001, the outstanding amount for the note receivable was $1.3 million. Gain on Sale of Investments. In the year ended June 30, 2001, as a result of the acquisition of a company in which the Company had an equity investment of $300,000, the Company received a total consideration of $1.4 million, resulting in a pre-tax gain of $1.1 million. This consideration does not include a hold back of approximately $167,000. Interest Expense. For the year ended June 30, 2001, the Company had a net interest expense of $995,000 compared to net interest expense of $721,000 for fiscal 2000. The increase in net interest expense was primarily due to increased borrowing on the Company's lines of credit for working capital and repurchase of Company stock. Subsequent to the sale of SMI, the Company repaid most of its lines of credit. Provision (benefit) for Income Taxes. For the year ended June 30, 2001, the Company had an income tax expense of $1.3 million compared to an income tax benefit of $151,000 for fiscal 2000. The change in the Company's effective tax rate was primarily due to a mix in income from U.S. and foreign operations and an increase in the valuation allowance of $2.2 million, offset in part by the release of certain tax contingencies. The 25

Company has established the valuation allowance in accordance with the provisions of SFAS No. 109. The valuation allowance primarily relates to federal and state net operating loss carry-forwards of a subsidiary subject to Separate Return Limitation Year rules. Net Income. For the reasons outlined above, the net income for the year ended June 30, 2001 was $3.5 million compared to $627,000 for the year ended June 30, 2000. Comparison of Fiscal Year Ended June 30, 2000 to Fiscal Year Ended June 30, 1999 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 intercompany eliminations. Revenues for the fiscal year ended June 30, 2000, increased by $9.2 million or 9.0% to $110.9 million from $101.8 million for the fiscal year ended June 30, 1999. Revenues for the sale of optoelectronics and silicon pressure sensor devices, subsystems and medical imaging systems, net of intercompany eliminations, increased by $8.3 million, or 15.0% to $63.8 million from $55.5 million for fiscal 1999. The increase was primarily due to increased sales of silicon pressure sensors through the recent acquisition of SMI and sales through the introduction of new product for the data/video projection market and was partially offset by a decrease in sales to the oil exploration industry. Revenues from the sale of security and inspection products increased $853,000, or 1.8% to $47.1 million from $46.3 million for fiscal 1999. The increase was primarily due to increased sales of people scanners and sales of walk-through metal detection systems through the recent acquisition of Metorex Security. Also for the year ended June 30, 1999, the Company had large shipments of cargo scanning machines, which were not repeated in fiscal 2000. Gross Profit. Cost of goods sold consist of material, labor and manufacturing overhead. Gross profit increased by $1.2 million or 4.1% to $30.3 million from $29.1 million for fiscal 1999. As a percent of revenues, gross profit decreased to 27.3% in fiscal 2000 from 28.6% in fiscal 1999. The increase in gross profit was due to an increase in revenues and a decrease in gross profit as a percentage of revenues was due to a change in product mix and introduction of a new product line for the sale of data/video projectors, which has a lower gross margin. 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, 2000, such expenses increased by $2.1 million or 11.8% to $19.8 million from $17.7 million in fiscal 1999. As a percentage of revenues, selling, general and administrative expenses increased to 17.9% in fiscal 2000 from 17.4% in fiscal 1999. The increase in expenses was due primarily to the inclusion of entire years selling, general and administrative expenses of recent acquisitions, increased administrative expenses, increased marketing expenses for the sales of medical products and was offset in part by proceeds from the settlement of certain litigation. Also for the fiscal 1999, the Company had exchange rate losses of $743,000, compared to $156,000 in fiscal 2000. Research and Development. Research and development expenses include research related to new product development and product enhancement expenditures. For the year ended June 30, 2000, such expenses increased by $2.0 million, or 35.0%, to $7.7 million from $5.7 million in fiscal 1999. As a percentage of revenues, research and development expenses increased to 6.9% in fiscal 2000 from 5.6% in fiscal 1999. The increase in expenses was primarily due to the increase in personnel cost resulting from the Company's recently acquired subsidiaries, continued enhancement of Rapiscan x-ray systems, and introduction of new products. Goodwill Amortization. Amortization of goodwill decreased to $529,000 in fiscal 2000 from $595,000 in fiscal 1999. The decrease in amortization of goodwill was the net result of a one time write-off of goodwill due to the closure of the Company's Denmark facility and partially offset by the inclusion of goodwill associated with the acquisition of OSI Medical and additional payment associated with the acquisition of Metorex Security. 26

Restructuring Costs. In August 1999, the Company decided to close the operation of Osteometer Denmark, and relocate certain of these operation to the Company's U.S. facilities. For the year ended June 30, 2000, the Company recorded restructuring costs of $1.9 million related to the closure of the Osteometer facility in Denmark. These costs were associated primarily with the termination of certain employees, commitments and other facility closure costs. The Company has completed the closure of Osteometer facility in Denmark. Of that amount, $1.8 million was paid in the year ended June 30, 2000 and $52,000 was included in other accrued expenses and current liabilities as of June 30, 2000. Based on the current estimates, the Company anticipates that the current restructuring accruals are sufficient. Income (loss) from operations. For the year ended June 30, 2000, income from operations was $373,000 compared to a loss of $1.9 million in fiscal 1999. Excluding the non-recurring restructuring costs of $1.9 million in the year ended June 30, 2000 and $458,000 for the year ended June 30, 1999 and a non-recurring in process research and development charge of $2.6 million and an asset impairment charge of $4.0 million in the year ended June 30, 1999, income from operations decreased to $2.3 million for the year ended June 30, 2000 compared to $5.1 million in fiscal 1999. Income from operations decreased primarily due to increased selling, general and administrative expenses, increased research and development expenses. Interest expense (income). For the year ended June 30, 2000, the Company had net interest expense of $721,000 compared to net interest income of $102,000 for fiscal 1999. The net interest expense 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. Gain on Sale of Marketable Securities. Gain on marketable securities for the year ended June 30, 2000, consisted of realized gain on the sale of marketable securities available for sale. Other Income. Other income for the year ended June 30, 2000, consisted of a debt settled for less than its recorded amount. Provision (benefit) for income taxes. For the year ended June 30, 2000, the Company had an income tax benefit of $151,000 compared to $2.6 million for fiscal 1999. Excluding, the non-recurring restructuring costs for the year ended June 30, 2000 and non-recurring in process research and development charge and restructuring costs for the year ended June 30, 1999, benefit for income taxes for the year ended June 30, 2000, was $151,000, compared to provision for income taxes of $231,000 for fiscal 1999. The reduction in the Company's effective tax rate was primarily due to a mix in income from U.S. and foreign operations and utilization of previously unrealized net operating losses. Net Income. For the reasons outlined above, the net income for the year ended June 30, 2000 was $627,000 compared to $741,000 for the year ended June 30, 1999. Excluding non-recurring restructuring costs for the year ended June 30, 2000 and non-recurring in process research and development charge, asset impairment charge, and restructuring costs for the year ended June 30, 1999, net income for fiscal 2000 decreased by 49.1% to $2.5 million compared to $5.0 million for fiscal 1999. 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 public offering. As of June 30, 2001, the Company's principal source of liquidity consisted of $4.5 million in cash and several credit agreements described below. The Company's operations provided net cash of $94,000 during fiscal 2001 compared to net cash used in operations of $1.3 million in fiscal 2000. The amount of net cash provided by operations reflects reductions in other receivables, an increase in accrued payroll and related expenses and advances from customers. Net cash provided by operations was offset in part by increase in accounts receivables, inventory and prepaids, and 27

reduction in accounts payable and other accrued expenses and current liabilities. The increase in accounts receivable was mainly due to timing of shipments of certain large contracts and increase in inventory was due to product mix and longer intercompany in transit time due to certain manufacturing being moved to Malaysia from the United States and the United Kingdom. The net cash provided by investing activities was $3.8 million during fiscal 2001, compared to net cash used in investing activities of $1.3 million in fiscal 2000. In fiscal 2001, net cash provided by investing activities reflects primarily cash received from the sale of SMI, the sale of property and equipment and sale of an equity investment and was offset in part by cash used in business acquisitions and the purchase of property and equipment. In fiscal 2000, the net cash used in investing activities reflects primarily cash used in business acquisitions and the purchase of property and equipment and was offset in part by the sale of marketable securities. Net cash used in financing activities was $10.4 million in fiscal 2001, compared to net cash provided by financing activities of $6.1 million for fiscal 2000, net cash used in financing activities resulted primarily due to the repayment of borrowings under the Company's working capital lines of credit, term loan and purchase of the Company's common share pursuant to its stock repurchase program. In March 1999, the Company announced a stock repurchase program of up to 2,000,000 shares of its common stock. Through September 27, 2001, the Company repurchased 1,404,500 shares at an average price $4.37 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. In January 1997, the Company and its U.S. subsidiaries entered into a credit agreement with United California Bank (previously Sanwa Bank California). The agreement, as amended and restated in February 2001, provides for a $12.0 million line of credit, which includes revolving line, letter of credit, acceptance and foreign exchange facilities. In addition, the Company has a $10.5 million term loan. Advances under the lines of credit bear interest at a rate equal to a variable bank reference rate plus a margin (7.0% at June 30, 2001) or, at the Company's option, at a fixed rate as quoted by the bank upon request for specific advances. As of June 30, 2001 there was no amount outstanding under the line of credit, $9.6 million outstanding under the term loan, and the Company was holding a forward exchange contract with a notional amount of $1.5 million. As of June 30, 2001, $574,000 was outstanding under letters of credit. The lines expire in November 2002. Borrowings under the agreement are secured by liens on substantially all of the assets of the Company's U.S. subsidiaries. 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 EBITDA of not more than 3.25 to 1; a ratio of cash, cash equivalents and accounts receivable to current liabilities of not less than 1.0 to 1; and a debt coverage ratio of 1.5 to 1. Rapiscan U.K. has a loan agreement with HSBC Bank plc, which provides for an overdraft facility up to a maximum amount of 2.0 million Pounds Sterling (approximately $2.8 million at June 30, 2001) outstanding at any one time, which amounts are secured by certain assets of Rapiscan U.K. At June 30, 2001, no amounts were outstanding under the overdraft facility. Outstanding borrowings bear interest at a base rate (5.25% at June 30, 2001) plus 1.35% per annum. The agreement also provides for a 1.0 million Pounds Sterling (approximately $1.4 million at June 30, 2001) facility for tender and performance bonds and a 1.0 million Pounds Sterling (approximately $1.4 million at June 30, 2001) facility for the purchase of forward exchange contracts. These facilities are secured by certain assets of Rapiscan U.K. and the Company has guaranteed this obligation up to $1.4 million. As of June 30, 2001, $714,000 was outstanding under the performance bond. The above facilities expire in January 2002 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 2.6 million Singapore dollars (approximately $1.4 million at June 30, 2001). Borrowings under the line of credit bear interest at the bank's prime rate (6.75% at June 30, 28

2001) plus 1.0%. The line of credit expires on April 2002 and the Company believes that it will be renewed on the same or similar terms. As of June 30, 2001 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 Den Norske Bank which provides for a revolving line of credit for borrowings of up to 10.0 million Norwegian kroner (approximately $1.1 million at June 30, 2001). As of June 30, 2001, no amounts were outstanding under this line of credit. Borrowings under the line of credit bear interest at a variable rate, which was 9.0% at June 30, 2001. The line of credit expires on January 2002, and the Company believes that it will be renewed on the same or similar terms. OSI Malaysia has a loan agreement with the Hong Kong Bank Malaysia Berhad, which provides for a bank guarantee line of credit for 10.0 million Malaysia ringgits (approximately $2.6 million at June 30, 2001) for performance bonds and a 2.0 million Malaysian ringgits overdraft facility (approximately $526,000 at June 30, 2001). Borrowings under the overdraft facility bear interest at the bank's base lending rate (6.8% at June 30, 2001) plus 1.75%. At June 30, 2001, the amounts outstanding under the performance bond and overdraft facilities was $61,000 and $100,000, respectively. Borrowings under this agreement are secured by certain assets of OSI Malaysia and are guaranteed by the Company. These lines expire in October 2001 and the Company believes that they will be renewed on the same or similar terms. OSI Malaysia has a loan agreement with Malaysian Bank Berhad, which provides for a revolving line of credit of up to an amount of 3.0 million Malaysian ringgits (approximately $789,000 as of June 30, 2001). Borrowings under the line of credit bear interest at the bank's base lending rate (6.75% at June 30, 2001) plus 1.75%. As of June 30, 2001, no amount was 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 expires in January 2002 and the Company believes that it will be renewed on the same or similar terms. Metorex Security has a loan agreement with Sampo Bank that provides for a foreign currency overdraft facility up to 4.0 million Finnish markka (approximately $570,000 at June 30, 2001). At June 30, 2001, no amount was outstanding under the overdraft facility. The agreement also provides for 2.0 million Finnish Marks (approximately $285,000 at June 30, 2001) for tender and performance bonds. At June 30, 2001 approximately $135,000 was outstanding under the tender and performance bonds facility. Borrowings under these facilities bear interest rate at the bank's prime lending rate (4.75% at June 30, 2001) plus 0.75%. The above facilities expire in March 2003, and the Company believes that they will be renewed on the same or 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. New Accounting Pronouncements Effective July 1, 2001, the Company adopted Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities", as amended. SFAS No. 133, as amended, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. Under SFAS No. 133, certain contracts that were not formerly considered derivatives may now meet the definition of a derivative. SFAS No. 133 requires that all derivatives be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income ("OCI"), depending on whether a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. The adoption of FAS 133 did not have a material impact on the Company's financial position or results of operations. In December 1999, the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements", and related interpretations. SAB 101 29

summarized certain of the SEC's views in applying accounting principles generally accepted in the United States to revenue recognition in financial statements. During the fourth quarter of fiscal 2001 the Company has retroactively adopted the provisions of SAB 101 effective July 1, 2000. The adoption of SAB 101 did not have a material impact on the Company's financial position or results of operations. In July 2001, the Financial Accounting Standards Board ("FASB") issued SFAS No. 141, "Business Combinations", which requires that all business combinations initiated after June 30, 2001 be accounted for under the purchase method and prohibits the use of the pooling-of-interests method. The Company does not believe that the adoption of SFAS No. 141 will have any effect on its financial position and results of operations. In July 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets", which becomes effective for the Company beginning fiscal year 2003. This statement changes the method of accounting for goodwill to a test for impairment and requires among other things, the discontinuance of goodwill amortization. The Company is currently assessing the impact of the adoption of this statement on its financial position and result of operations. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS 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 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. Foreign Currency The accounts of the Company's operations in Singapore, Malaysia, England, Finland, Norway and Canada are maintained in Singapore dollars, Malaysian ringgits, Pounds Sterling, 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 $156,000 and $288,000 were included in income for fiscal 2000 and 2001, respectively. The Company's use of derivatives consists primarily of foreign exchange contracts and an interest rate swap. The Company purchases forward contracts to hedge foreign exchange exposure related to commitments to acquire inventory for sale. The Company does not use the contracts for trading purposes. As of June 30, 2001, the Company had one foreign exchange contract with a notional amount of $1.5 million. The estimated fair value of these contracts, based on quoted market prices, approximated ($50,000) at June 30, 2001. The foreign exchange contract is an effective foreign exchange hedge and the difference in the fair value from the prior reporting period has been recorded as OCI. 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. 30

For the year ended June 30, 2001, 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 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. Due to its overseas investments and the necessity of dealing with local currencies in its foreign business transactions, the Company is at risk with respect to foreign currency fluctuations. Inflation The Company does not believe that inflation has had a material impact on its results of operations. Euro Conversion On January 1, 1999, 11 of the 15 member countries of the European Union introduced a new currency, the "Euro". The conversion rates between the Euro and the participating nations' existing legacy currencies were fixed irrevocably as of December 31, 1998. Prior to full implementation of the new currency on January 1, 2002, there will be a transition period during which parties may, at their discretion, use either the legacy currencies or the Euro for financial transactions. We are not aware of any material operational issues or costs associated with preparing internal systems for the Euro. While it is not possible to accurately predict the impact the Euro will have on the Company's business or on the economy in general, management does not anticipate that the Euro conversion will have a material adverse impact on the Company's market risk with respect to foreign exchange, its results of operations, or its financial condition. Interest Rate Risk All highly-liquid investments with a maturity of three months or less are classified as cash equivalent and recorded in the balance sheet at fair value. Short-term investments are comprised of high quality marketable securities. We have not historically used derivatives to hedge our interest rate risk. However, during the current fiscal year we entered into a interest rate swap to convert a portion of the Company's variable-interest-rate debt to a fixed- rate liability. The carrying amount, principal maturity and estimated value of our investment portfolio and long-term debt exposure as of June 30, 2000 are as follows: Carrying Amount Maturity -------- --------------------------------- Fair 2000 2001 2002 2003 2004 2005 Value -------- ----- ----- ----- ----- ----- ------ Investments Cash and cash equivalents............ 10,892 10,892 Average interest rate... 5.51% Long-term debt Secured long-term loan.. 10,339 2,641 2,609 2,554 1,499 1,036 10,339 Average interest rate... 8.75% 9.50% 9.50% 9.50% 9.50% 9.50% 31

The carrying amount, principal maturity and estimated value of our investment portfolio and long-term debt exposure as of June 30, 2001 are as follows: Carrying Amount Maturity -------- -------------------------------- Fair 2001 2002 2003 2004 2005 2006 Value -------- ----- ----- ----- ----- ---- ----- Investments Cash and cash equivalents..... 4,467 4,467 Average interest rate......... 6.67% Long-term debt Secured long term loan........ 9,628 2,625 2,628 2,625 1,750 9,628 Average interest rate......... 6.95% 6.95% 6.95% 6.95% 6.95% During the current year, the Company also entered into an interest rate swap. The terms of the swap are to convert a portion of the company's variable interest rate debt into a fixed rate liability. At year-end, the fair value of the swap was ($50,000). The decrease in the market value from the date of purchase of the swap to year-end is recorded in OCI, due to the swap meeting the criteria of an effective cash flow hedge. ITEM 8.

INDEPENDENT AUDITORS' REPORT OSI Systems, Inc.: We have audited the accompanying consolidated balance sheets of OSI Systems, Inc. and subsidiaries (the "Company") as of June 30, 2001 and 2000, and the related consolidated statements of operations, shareholders' equity, and cash flows for each of the three years in the period ended June 30, 2001. Our audits also included the financial statement schedule listed in the index 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 and financial statement schedule based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. 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, 2001 and 2000, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2001 in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein. /s/ Deloitte & Touche LLP Los Angeles, California September 17, 2001 F-1

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Years Ended June 30, 1999, 2000, and 2001 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES General--OSI Systems, Inc. and its subsidiaries (collectively, the "Company") is a vertically integrated, worldwide provider of devices, subsystems, and end-products based on optoelectronic technology. The Company designs and manufactures optoelectronic devices and value-added subsystems for original equipment manufacturers ("OEMs") in a broad range of applications, including security, medical diagnostics, fiber optics 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. In the medical field, the Company manufactures and sells bone densitometers, which are used to provide bone loss measurements in the diagnosis of osteoporosis. The Company also manufactures and sells saturation of arterial hemoglobin ("SpO\\2\\") monitors and sensors under the trade names "Digital Dolphin" and "Dolphin 2000." 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. Cash Equivalents--The Company considers all highly liquid investments purchased with maturity of three months or less to be cash equivalents. Investments--Investments consist of equity securities categorized as available-for-sale and carried at fair value. Unrealized holding gains and losses on investments are included in accumulated other comprehensive loss until realized. Fair value of investments is determined by the quoted market prices of each investment. For purposes of determining gross realized gains and losses, the cost of the securities sold is based upon specific identification. Investments held at June 30, 2001 are restricted and cannot be sold by the Company until April 1, 2002. Concentrations of Credit Risk--The Company's financial instruments that are exposed to concentration of credit risk consist primarily of its cash, cash equivalents, available-for-sale investments, and accounts receivable. The Company restricts investments in cash equivalents and available-for-sale investments to financial institutions with high credit standing. Credit risk on accounts receivable is minimized as a result of the large and diverse nature of the Company's worldwide customer base. The Company performs ongoing credit evaluations of its customers' financial condition and maintains allowances for potential credit losses. Accounts Receivable--Accounts receivable at June 30, 2000 and 2001 consisted of the following (in thousands): 2000 2001 ------- ------- Trade receivables, net...................................... $29,890 $27,113 Receivables related to long term contracts Unbilled costs and accrued profit on progress completed... 1,324 ------- ------- Total................................................... $29,890 $28,437 ======= ======= The unbilled costs and accrued profit at June 30, 2001 are expected to be entirely billed and collected during fiscal 2002.

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Years Ended June 30, 1999, 2000, and 2001 Inventory--Inventory is stated at the lower of cost or market; cost is determined on the first-in, first-out method. Inventory at June 30, 2000 and 2001 consisted of the following (in thousands): 2000 2001 ------- ------- Raw materials................................................ $16,877 $16,442 Work-in-process.............................................. 6,619 6,595 Finished goods............................................... 7,424 8,137 ------- ------- Total...................................................... $30,920 $31,174 ======= ======= 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. Property and equipment at June 30, 2000 and 2001 consisted of the following (in thousands): 2000 2001 ------- ------- Land and buildings.......................................... $ 4,211 $ 4,211 Equipment................................................... 12,790 13,108 Leasehold improvements...................................... 4,284 4,564 Tooling..................................................... 2,213 2,033 Furniture and fixtures...................................... 1,218 1,294 Computer.................................................... 3,667 4,050 Vehicles.................................................... 194 145 ------- ------- Total....................................................... 28,577 29,405 Less accumulated depreciation and amortization.............. 14,329 16,000 ------- ------- Property and equipment, net................................. $14,248 $13,405 ======= ======= Intangible and Other Assets--Intangible and other assets at June 30, 2000 and 2001 consisted of the following (in thousands): 2000 2001 ------- ------ Purchased software........................................... $ 474 $ 477 Software development costs................................... 588 701 Goodwill and identified intangible assets.................... 8,374 6,785 Joint venture and equity investments......................... 579 413 Deposits..................................................... 121 125 Other........................................................ 558 735 ------- ------ Total........................................................ 10,694 9,236 Less accumulated amortization................................ 1,642 1,865 ------- ------ Intangible and other assets, net............................. $ 9,052 $7,371 ======= ====== F-9

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Years Ended June 30, 1999, 2000, and 2001 At June 30, 2000 and 2001, goodwill and identified intangible assets consisted of the following as a result of the following acquisitions (in thousands): 2000 2001 ------ ------ Acquisition of minority interests............................. $1,554 $1,554 Acquisition of Advanced Micro Electronics AS ("AME").......... 588 588 Acquisition of Metorex Security............................... 3,474 3,075 Acquisition of SMI............................................ 1,470 Acquisition of Corrigan....................................... 110 108 Acquisition of Aristo......................................... 27 27 Acquisition of OSI Medical.................................... 1,151 1,433 ------ ------ $8,374 $6,785 ====== ====== 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 Company amortizes these costs on a straight-line basis over a two- to five-year period, once it is put into use. No software development costs were capitalized during the years ended June 30, 1999 and 2000. During the year ended June 30, 2001, the Company capitalized $113,000 of software development costs. 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. Other Income--Other income consists of a debt settled with the Danish government for less than its recorded amount. 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, investments, 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. Derivative Instruments--The Company's use of derivatives consists of the purchase of foreign exchange contracts, in order to attempt to reduce foreign exchange transaction gains and losses, along with an interest rate swap on a variable interest rate term loan. The Company purchases forward contracts to hedge foreign exchange exposure related to commitments to acquire inventory for sale and does not use the contracts for trading F-10

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Years Ended June 30, 1999, 2000, and 2001 purposes. As of June 30, 2001 and 2000, notional amounts were approximately $1,451,000 and $508,000 for outstanding foreign exchange contracts, respectively. The estimated fair value of these contracts, based on quoted market prices, approximated ($50,000) at June 30, 2001. The estimated fair value of foreign exchange contracts as of June 30, 2000 was not significant. The foreign exchange contracts are effective foreign exchange hedges and the difference in the fair value from the prior reporting period has been recorded as other comprehensive income (loss). During the current year, the Company also entered into an interest rate swap. The terms of the swap are to convert a portion of the Company's variable interest rate debt into a fixed rate liability. At June 30, 2001, the notional amount of the swap was $5,042,000 and the fair value of the swap was ($50,000). The decrease in the market value from the date of purchase of the swap to year-end is recorded in other comprehensive income (loss), due to the swap meeting the criteria of an effective cash flow hedge. All forward contracts, swaps, and underlying transaction exposures are carried at fair value in other accrued expenses and liabilities in the accompanying consolidated balance sheets. Revenue Recognition--The Company generally recognizes revenue upon shipment of its products. Concurrent with the shipment of the product, the Company accrues estimated product return reserves and warranty expenses. The Company has undertaken projects which include the development and construction of large complex cargo inspection systems requiring installation and customization at the customer's site. Sales under such long-term contracts are recorded under the percentage of completion method. Costs and estimated revenues are recorded as work is performed based on the percentage that incurred costs bear to estimated total costs utilizing the most recent estimates of costs. If the current contract estimate indicates a loss, provision is made for the total anticipated loss in the current period. Foreign Currency Translation--The accounts of the Company's operations in Singapore, Malaysia, Norway, Finland, Canada, and the United Kingdom are maintained in Singapore dollars, Malaysian ringgits, 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 accumulated other comprehensive loss. Transaction losses of approximately $743,000, $156,000, and $288,000 were included in income for the years ended June 30, 1999, 2000, and 2001, respectively. Restructuring Costs--The Company adopted a restructuring plan in the quarter ended March 31, 1999. In August 1999, the Company decided to close the operations of Osteometer in Denmark, and to relocate certain of these operations to the Company's U.S. facilities. The Company recorded $458,000 and $1,898,000 of restructuring costs for the years ending June 30, 1999 and 2000, respectively, associated primarily with the termination of certain employees, lease commitments, and other facility closure costs. The restructuring was completed in the year ending June 30, 2000, and no further costs were incurred in the year ended June 30, 2001. Earnings per Share--The Company has adopted Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings per Share."

SFAS No. 133, as amended, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. Under SFAS No. 133, certain contracts that were not formerly considered derivatives may now meet the definition of a derivative. SFAS No. 133 requires that all derivatives be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income (loss), depending on whether a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. The adoption of SFAS No. 133 did not have a material impact on the Company's financial position or results of operations. F-12

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Years Ended June 30, 1999, 2000, and 2001 In December 1999, the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements," and related interpretations. SAB 101 summarized certain of the SEC's views in applying accounting principles generally accepted in the United States to revenue recognition in financial statements. During the fourth quarter of fiscal 2001, the Company has retroactively adopted the provisions of SAB 101 effective July 1, 2000. The adoption of SAB 101 did not have a material impact on the Company's financial position or results of operations. In July 2001, the Financial Accounting Standards Board ("FASB") issued SFAS No. 141, "Business Combinations," which requires that all business combinations initiated after June 30, 2001 be accounted for under the purchase method and prohibits the use of the pooling-of-interests method. The Company does not believe that the adoption of SFAS No. 141 will have any effect on its financial position and result of operations. In July 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets," which becomes effective for the Company beginning fiscal year 2003. This statement changes the method of accounting for goodwill to a test for impairment and requires, among other things, the discontinuance of goodwill amortization. The Company is currently assessing the impact of the adoption of this statement on its financial position and result of operations. Use of Estimates--The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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. Reclassifications--Certain reclassifications have been made to prior year amounts to conform to the current year's presentation. 2.

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Years Ended June 30, 1999, 2000, and 2001 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 fiscal 1999, 2000, and 2001 pursuant to SFAS No. 123 was approximately $1,272,000, $867,000, and $1,000,000, respectively. Had the Company adopted SFAS No. 123, pro forma net (loss) income would have been $(213,000), $23,000, and $2,774,000 and pro forma net (loss) income per share would have been $(0.02), $0.00, and $0.30 for fiscal 1999, 2000, and 2001, 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 104 percent in fiscal 2001 (2000 and 1999, 109 percent and 71 percent, respectively), a risk-free interest rate of 5.14 percent in fiscal 2001 (2000 and 1999, 6.39 percent and 5.67 percent, respectively), and expected option lives of five years. 9. EMPLOYEE STOCK PURCHASE PROGRAM In August 1998, the board of directors adopted the Company's Employee Stock Purchase Plan (the "1998 Plan"). The 1998 Plan, which was approved by the Company's shareholders in November 1998, provides persons who have been regular employees of the Company or its U.S. subsidiaries for at least six months, and who meet certain other criteria, the opportunity to purchase through regular payroll deductions up to an aggregate of 200,000 shares of common stock. The 1998 Plan is administered by the board of directors, or a committee of the board. The 1998 Plan qualifies as an "employee stock purchase plan" as defined in Section 423 of the Internal Revenue Code. To participate in the 1998 Plan, eligible employees submit a form to the Company's payroll office authorizing payroll deductions in an amount between 1 percent and 10 percent of the employee's regular annual pay. At the end of each offering period, initially set at six months duration, the aggregate amount deducted from each participating employee's paycheck is applied to the purchase of a whole number of shares of common stock, with any sums remaining being returned to the employee. No interest accrues on payroll deductions. The purchase price of the common stock is 85 percent of the lesser of the fair market value of the common stock (as determined by the board of directors) on the first day or the last day of the offering period. If the aggregate number of shares of common stock that all participants elect to purchase during any offering period is greater than the number of shares remaining available for issuance under the 1998 Plan, the remaining shares will be allocated pro rata among participants. Not withstanding any of the foregoing, no employee may purchase common stock under the 1998 Plan if (i) after any such purchase, the employee would own 5 percent or more of the total combined voting power or value of all classes of the Company's stock on a consolidated basis, or (ii) the rights to purchase common stock under the 1998 Plan and all other qualified employee stock purchase plans of the Company or any of its subsidiaries granted to that employee would exceed $25,000 per calendar year. A participant may elect to withdraw from the 1998 Plan at any time up to the last day of an offering period by filing a form to such effect. Upon withdrawal, the amount contributed to the employee will be refunded in cash, without interest. Any person withdrawing may not participate again in the 1998 Plan until the end of one complete offering period. Termination of a participant's employment for any reason shall be treated as a withdrawal. The Plan purchased 10,674 shares of common stock, for a total of $46,000 during the year ended June 30, 2000 and an additional 10,093 shares of common stock for a total of $50,000 during the year ended June 30, 2001. The Company's liability to the Plan was $23,000 and $45,000 at June 30, 2000 and 2001, respectively. F-22

SHAREHOLDERS' EQUITY 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. The Company purchased 405,500 shares at a cost of $1,820,000 during fiscal 2000, and an additional 914,000 shares for $3,886,000 during fiscal 2001. The Company retires the treasury shares as they are repurchased, and they are disclosed as a deduction from common shares in the accompanying financial statements. 11. 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, 1999, 2000, and 2001 are approximately $103,000, $90,000, $112,000 for messenger service and auto rental; $76,000, $46,000, and $178,000 for printing services; and $4,000, $9,000, and $0 for professional services, respectively. 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 employee. The Company made no contributions to the plan for the years ended June 30, 1999, 2000, and 2001. During 1993, 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, 1999, 2000, and 2001 was approximately $138,000, $125,000, and $84,000, respectively. Additional information about the plan is not disclosed, as the plan is not considered to be material. During 2000, AME established a defined contribution plan. The plan provides for contributions by AME at a fixed percentage of employee salaries. Contributions made during the years ended June 30, 2000 and 2001 by AME were approximately $130,000 and $38,000, respectively. F-23
