PART I ITEM 1. BUSINESS General The Company is a vertically-integrated, worldwide provider of devices, subsystems and end-products based on optoelectronic and silicon pressure- sensor microstructure technology. The Company designs and manufactures optoelectronic and silicon pressure-sensor devices and value-added subsystems for original equipment manufacturers ("OEMs") for use in a broad range of applications, including security, medical diagnostics, 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 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. In fiscal 2000, revenues from the sale of optoelectronic and silicon pressure-sensor devices and subsystems and medical imaging systems amounted to $63.8 million, or approximately 57.5% of the Company's revenues, while revenues from sales of security and inspection products amounted to $47.1 million, or approximately 42.5% of the Company's revenues. Further information concerning market segments is available in Note 15 to the Company's financial statements, at page F-23. Unless the context otherwise requires, the term the "Company" as used herein includes OSI Systems, Inc., a California corporation, and its subsidiaries. Industry Overview The Company's optoelectronic and silicon pressure-sensor devices and subsystems are designed and manufactured primarily for sale to OEMs, while the Company's security products and medical imaging systems are sold to end-users. Optoelectronic and Silicon Pressure-Sensor Devices and Subsystems. Optoelectronic devices consist of both active components, such as silicon photodiodes that sense light of varying wavelengths and convert the light detected into electronic signals, and passive components, such as lenses, prisms, filters and mirrors. An optoelectronic subsystem typically consists of one or more optoelectronic devices that are combined with other electronic components for integration into an end-product. Optoelectronic devices and subsystems, and medical imaging systems, are used for a wide variety of applications ranging from simple functions, such as the detection of paper in the print path of a laser printer, to complex monitoring, measurement or positioning functions, such as in industrial robotics where the subsystem is used to detect the exact position, motion or size of another object. Because optoelectronic devices and subsystems can be used in a wide variety of measurement, control and monitoring applications, optoelectronics may be used in a broad array of industrial applications. 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

Silicon pressure-sensors and microstructures are based upon the same process technologies as the optoelectronic components and are also used as components in a variety of applications primarily in the automotive, medical, and industrial markets. Typical applications include pressure sensing in fuel vapor systems, engine controls, respiration and anaesthesia machines, and industrial pressure transducers, and heating, venting and air-conditioning markets. The Company sells its products in die form to other sensor companies as well as packaged parts. A primary focus of the Company's pressure products has been in the precision low-pressure segment of the silicon sensor market, where the performance of its parts allow replacement of non-silicon sensors with lower cost silicon components. The Company formed RapiTec, Inc., a majority-owned subsidiary, in fiscal 2000 which has enabled the Company to further penetrate 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 recently 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. A recent product developed by the Company is a silicon-based fiber optic detector which can achieve a 2.5 Gigabit/second data rate using 3.3 volts bias voltage. In order to further develop and market fiber optic products, the Company has recently formed a new subsidiary, OSI Fibercomm, Inc., which 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"). Medical Diagnostic and Imaging Systems. The Company has expanded into medical diagnostic and imaging systems. The Company manufactures and distributes the DTX 200 (DEXACARE) and U.S. Food & Drug Administration ("FDA")-approved forearm DEXA (Dual Energy X-Ray) densitometer, which is used to diagnose osteoporosis as well as to provide follow-up bone density measurements. The Company also produces the ultrasound DTU-One, the first commercially available ultrasound scanner using imaging capability for the diagnosis of osteoporosis. The DTU-One has not previously been available for sale in the United States, but in September, 2000, the Company received pre- market approval ("PMA") from the FDA, and is now authorized to sell the DTU- One in the United States. The Company has 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 are first exercisable commencing on April 12, 2001. In August 1998, the Company acquired a 16% interest in Square One Inc., which develops and manufactures infrared-based patient monitoring medical subsystems, and in August 2000, the Company acquired substantially all of the assets of Square One. 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, 2

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 on Aviation Safety and Security (the "Gore Commission"), to review airline and airport security and to oversee aviation safety. In response to the initial report released by the Gore Commission, the United States enacted legislation that includes $144 million in appropriations for the initial deployment of advanced security and inspection technology at major U.S. airports. The Clinton Administration is continuing to fund procurements of $100 million annually for state-of-the-art detection equipment at major U.S. airports. A portion of this funding is allocated for TIP Ready X-ray (TRX) systems at security checkpoints throughout the nation. 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. The initial purchase under the contract is for approximately 100 carry-on baggage x-ray screening systems. Under the contract, the FAA has the right to purchase up to 800 systems, for which the purchase price would be approximately $40 million. X-ray inspection equipment, such as that sold by the Company, is also increasingly being used for a number of purposes not related to security. Newer versions of x-ray inspection equipment combine x-ray inspection with computer image enhancement capabilities and can be applied to various non- security purposes such as the detection of narcotics, gold and currency, the inspection of agricultural products, and the inspection of cargo by customs officers and international shippers. Growth Strategy The Company's objectives are to be a leading provider of specialized optoelectronic and silicon pressure-sensor products, to enhance its position in the international inspection and detection marketplace and to leverage its expertise in the optoelectronic technology industry by entering into new end- product markets on a selective basis. Key elements of this strategy include: Leverage its Optoelectronic Design and Manufacturing Expertise to Address New Applications. The Company believes that one of its primary competitive strengths is its expertise in designing and manufacturing specialized optoelectronic subsystems for its OEM customers in a cost-effective manner. The Company currently designs and manufactures devices and subsystems for over 200 customers serving over 100 applications. The Company has developed this expertise in the past through internal research and development efforts and through selective acquisitions. In 1990, the Company acquired UDT Sensors, Inc. ("UDT Sensors") to broaden its expertise and capabilities in developing and manufacturing optoelectronic devices and subsystems. In 1993, the Company acquired Rapiscan Security Products Limited ("Rapiscan U.K.") and, through Rapiscan Security Products (U.S.A.), Inc. ("Rapiscan U.S.A.") (Rapiscan U.S.A. and Rapiscan U.K. are sometimes collectively referred to as "Rapiscan"), commenced its operations as a provider of security and inspection products in the United States. Thereafter, in 1993, the Company acquired Ferson Optics, Inc. ("Ferson Optics") for its passive optic technologies. In 1994, the Company commenced operations of Opto Sensors (Malaysia) Sdn. Bhd. ("OSI Malaysia") to take advantage of low cost manufacturing. In 1997, the Company acquired Advanced Micro Electronics AS ("AME") for AME's hybrid optoelectronic capabilities. In September 1998, the Company acquired Osteometer, a Danish manufacturer of diagnostic scanners used to detect osteoporosis. 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 3

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 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. As of June 30, 2000, per the purchase agreement, the Company may be required to pay up to an additional $2.4 million in cash, at a later date, based on sales made subsequent to the purchase. To date, the Company has not been required to make any such payments, and it does not anticipate that the circumstances will require it to do so in the future. The designs and processes of SMI allow leveraging of the Company's silicon wafer fabrication technologies to initially serve pressure sensor markets and extend into the future to a variety of products based on mechanical structures in silicon. In December 1998, the Company acquired most of the assets and assumed certain liabilities of Corrigan Canada Ltd. ("Corrigan"), a Canadian security products manufacturer, for approximately $476,000 in cash, including professional fees associated with the acquisition. In January 1999, the Company acquired Aristo Medical Products, Inc. ("Aristo") for approximately $277,000 in cash, including professional fees associated with the acquisition. Aristo develops and manufactures new generation pulse oximeter probes used in the medical field. In August 1998, the Company invested $315,000, including professional fees associated with the acquisition, in Square One Inc. ("Square One") for an equity share of approximately 16%, and in August 2000, the Company acquired substantially all of its assets for consideration of $228,000 in cash, future royalties, and return of the Square One stock held by the Company. The acquired business is the development and manufacturing of 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. With this additional equity investment, the Company increased its equity share in OSI Medical to approximately 56%. 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 are first exercisable commencing on April 12, 2001, and, if fully exercised, would result in the Company's share 4

in OSI Medical being increased to over 60%, based upon the number of shares presently outstanding. Also, pursuant to the OSI Medical Agreement, under certain circumstances 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. Further Penetrate Existing Security and Inspection Markets and Expand into Other Markets. During the fiscal year ended June 30, 2000, the Company continued to expand sales of its security and inspection products beyond the traditional focus on airports and airlines to include government buildings, customs facilities, courthouses, school districts, departments of corrections and businesses for their respective security and inspection needs. The Company intends to continue to expand its sales and marketing efforts both domestically and internationally to capitalize on opportunities in its existing markets for new installations as well as opportunities to replace, service and upgrade existing security installations. In addition, through research and development and selective acquisitions, the Company intends to enhance and expand its current product offering to better address new applications including automatic bomb detection and cargo scanning. The Company believes that its strategy will enable it to take advantage of the growth its existing markets are experiencing and to benefit from additional growth that these new and enhanced products will provide. Capitalize on Vertical Integration. The Company believes that it offers significant added value to its OEM customers by providing a full range of vertically-integrated services including component design and customization, subsystem concept design and application engineering, product prototyping and development, and efficient pre-production, short-run and high volume manufacturing. The Company believes that its vertical integration differentiates it from many of its competitors and provides value to its OEM customers, who can rely on the Company to be an integrated supplier of an optoelectronic subsystem. In addition, the Company's vertical integration provides several other advantages in both its optoelectronic devices and subsystems and security and detection product lines. These advantages include reduced manufacturing and delivery times, lower costs due to its access to competitive international labor markets and direct sourcing of raw materials, and quality control. Further leverage is obtained by extending the silicon wafer fabrication processes to manufacture the pressure sensors and microstructure processes of SMI. The Company intends to continue to leverage its vertically integrated services to create greater value for its customers in the design and manufacture of its products. The Company believes that this strategy better positions the Company for penetration into other end markets. Capitalize on Global Presence. The Company operates from locations in the United States, Europe, Asia and Canada. The Company views its international operations as providing an important strategic advantage over competitors in both the optoelectronic device and subsystem market and the security and inspection market for three primary reasons. First, international manufacturing facilities allow the Company to take advantage of competitive labor rates in order to be a low cost producer. Second, its international offices strengthen its sales and marketing efforts and its ability to service and repair its systems by providing direct access to growing foreign markets and to its existing international customer base. Third, multiple manufacturing locations allow the Company to reduce delivery times to its global customer base. In the future, the Company intends to develop new sources of manufacturing and sales capabilities to maintain and enhance the benefits of its international presence. Selectively Enter New End Markets. 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. 5

Products and Technology The Company designs, develops, manufactures and sells products based on its core optoelectronic and silicon pressure-sensor technology. These products range from discrete devices to value-added subsystems to complete x-ray security and inspection products, and medical imaging systems. Discrete Devices and Subsystems, and Medical Imaging Systems. Optoelectronic and silicon pressure-sensor devices generally consist of both active and passive components. Active components sense light of varying wavelengths and convert the light detected into electronic signals, whereas passive components amplify, separate or reflect light. Active components manufactured by the Company consist of silicon photodiodes and hybrid photodetectors. Passive components include lenses, prisms, filters, mirrors and other precision optical products that are used by the Company in the manufacture of its optoelectronic products or are sold to others for use in telescopes, laser printers, copiers, microscopes and other detection and vision equipment. A second group of discrete devices are the pressure sensors and microstructures of SMI. These are primarily manufactured in the same wafer fabrication facility as the optoelectronic components, thereby achieving greater utilization and economy of scale in this specialized facility. The same lithographic, furnace and metal processes are combined with silicon etching to form precise miniature electromechanical structures in silicon. SMI has developed specific structural designs that concentrate stresses and provide higher signals and improved performance over conventional silicon pressure sensors. The devices manufactured by the Company are both standard products and products customized for specific applications. Most of the devices manufactured by the Company are incorporated into the subsystems manufactured by the Company. The Company does, however, also sell its discrete devices separately to OEMs. Direct sales of devices to third parties constituted less than 10% of the Company's revenues in each of fiscal 1998, 1999 and 2000. In addition to the manufacture of discrete devices, the Company also specializes in designing and manufacturing customized optoelectronic subsystems for use in a wide range of products and equipment. An optoelectronic subsystem typically consists of one or more optoelectronic devices that are combined with other electronic components and packaging for use in an end-product. The composition of a subsystem can range from a simple assembly of various optoelectronic devices that are incorporated into other subsystems (for example, a printed circuit board containing the Company's optoelectronic devices), to complete end-products (for example, medical pulse oximeter probes that are manufactured and packaged by the Company on behalf of the OEM customer and then shipped directly to the customer or the customer's distributors). Since the end of fiscal 1996, the Company has manufactured subsystems for a variety of applications, including the following: 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 players, and ultra-violet fire detection subsystems for submarines and surface ships. The Company has also started manufacturing and shipping high-speed silicon based photodetectors and detector-amplifier hybrids serving the fiber-optics and telecommunications market in SAN, 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 (SAN, LAN, MAN, WAN) and other long haul telecommunications marketplace. The Company has also moved into the field of manufacturing and selling the DTX 200 (DEXACARE) and U.S. Food & Drug Administration ("FDA")-approved forearm DEXA (Dual Energy X-Ray) densitometer, which is used to diagnose osteoporosis as well as to provide follow-up bone density measurements. The Company also produces the ultrasound DTU-One, the first commercially available scanner using imaging capability for the diagnosis of osteoporosis. The DTU- One has not previously been available for sale in the United States, but in September, 2000, the Company received pre-market approval ("PMA") from the FDA, and is now authorized to sell the DTU-One in the United States. 6

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 1998, 1999 and 2000, approximately 22.0%, 20.5% and 26.1%, 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. The initial purchase under the contract is for 100 carry-on baggage x-ray screening systems. Under the contract, the FAA has the right to purchase up to 800 systems, for which the purchase price would be approximately $40 million. 7

Security and Inspection Products. Since entering the security and inspection products market in 1993, the Company has shipped approximately 4,500 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 Orlando Airport Kingdom Ronald Reagan National Airport INFRAERO, airports, Brazil U.S. Government Chek Lap Kok International Airport, California Department of Corrections Hong Kong U.S. Department of Corrections Pudong Shanghai International Airport, Empire State Building P.R. China World Trade Center Kremlin, Russia New Zealand Customs, New Zealand Vatican 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. 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 continue to be shipped during fiscal 2001. 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 2000, 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. During the second quarter of fiscal 2000, the Company received and completed a security system order in excess of $1.5 million from the Vatican. In the second quarter of fiscal 2000, the Company entered into a contract with a branch of the Mexican government for approximately $2.2 million for multiple Secure 2000 body scanners. 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. The initial purchase under the contract is for 100 carry-on baggage x-ray screening systems. Under the contract, the FAA has the right to purchase up to 800 systems, for which the total contract might be as high as approximately $40 million. 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 price of these units is approximately $9 million. Marketing, Sales and Service The Company markets and sells its optoelectronic and silicon pressure- sensor devices and subsystems, and medical imaging systems, worldwide through both a direct sales and marketing staff of 30 employees and indirectly through a network of approximately 45 independent sales representatives and distributors. Most of the in-house sales staff is based in the United States while most of the independent sales representatives and distributors are located abroad. Since the acquisition of AME in March 1997, the Company's marketing efforts in Europe have been conducted through AME's sales and marketing staff and through a network of approximately eight independent sales representatives. The Company markets and sells its security and inspection products worldwide through a direct sales and marketing staff of approximately 35 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 and silicon pressure-sensor 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 35 persons located primarily in the United States, the United Kingdom, Finland and Malaysia. The Company also supports these sales and customer relations efforts by providing operator training, computerized training and testing equipment, in-country service, software upgrades, service training for customer technicians and a newsletter on security issues. The Company considers its maintenance service operations to be an important element of its business. After the expiration of the standard product warranty period, the Company is often engaged by its customers to provide maintenance services for its security and inspection products through annual maintenance contracts. The Company believes that its international maintenance service capabilities allow it to be competitive in selling its security and inspection products. Furthermore, the Company believes that as its installed base of security and inspection products increases, revenues generated from such annual maintenance service contracts and from the sale of replacement parts will increase. In fiscal 1998, 1999 and 2000, maintenance service revenues and replacement part sales collectively represented 3.5%, 3.6% and 3.6% respectively, of the Company's revenues. Research and Development The Company's components and optoelectronic subsystems are designed and engineered at the Company's facilities in either Hawthorne and Fremont, California, or Horten, Norway. The subsystems that the Company 11

manufactures are engineered by the Company to solve specific application needs of its OEM customers. The Company's customers typically request that the Company design custom optoelectronic solutions for their specific needs when standard components or subsystems are not available from other manufacturers of optoelectronic and silicon pressure-sensor devices. After an end-product has been conceptualized by the OEM, the Company normally will involve its engineers to design the application, establish the mechanical specifications for the application, create the appropriate subsystem architecture for the application, and design the development, production and assembly process for the manufacture of the ultimate subsystem. However, because the Company has the engineering, tooling and manufacturing capabilities to design and manufacture entire subsystems, and not just a specific component, the Company typically also designs, manufactures and assembles the entire subsystem for the customer. Because the Company's engineers are able to provide additional value and services to its customers through the entire production process from concept to completion, the Company considers its engineering personnel to be an important extension of its core sales and marketing effort. In addition to close collaboration with the Company's customers in the design and development of optoelectronics-based products, the Company maintains an active program for the development and introduction of new products and enhancements and improvements to its existing products, including the implementation of new applications of its technology. The Company seeks to further develop its research and development program and considers such a program to be an important element of its business and operations. As of June 30, 2000, in addition to the engineers that the Company employed in manufacturing, process design and applications development, the Company engaged approximately 70 full-time engineers and technicians in research and development. During fiscal 2000 and 1999, the Company's research and development expenses were approximately $7.7 million and $5.7 million, respectively. A significant portion of the increase in research and development in fiscal 2000 is the result of acquisitions during fiscal 1999 and 2000. 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, Malaysia, Finland, Canada and Norway, in addition to its manufacturing facilities in Hawthorne and Fremont, 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 facilities in Malaysia. Since most of the Company's customers currently are located in Europe and the United States, the Company's ability to assemble its products in these markets and provide follow-on service from offices located in these regions is an important component of the Company's global strategy. The Company seeks to focus its subsystem manufacturing resources on its core competencies that enable it to provide value-added enhancements and distinctive value. The Company believes that its manufacturing organization has expertise in optoelectronic, electrical and mechanical manufacturing and assembly of products for commercial applications and for high reliability applications. High reliability devices and subsystems are those which are designed, manufactured, screened and qualified to function under exceptionally severe levels of environmental stress. The manufacturing techniques include silicon wafer processing and fabrication, manufacture and assembly of photodiodes, surface mounting (SMT) and manual thru-hole assembly, thick-film ceramic processing, wire bonding, molding, assembly of components, testing, and packaging. The Company also has the ability to manufacture plastic parts and certain other parts that are either not available from third party suppliers or that can be more efficiently or cost-effectively manufactured in- house. The Company outsources 12

certain manufacturing operations including its sheet metal fabrication. The manufacturing process for components and subsystems consists of manual tasks performed by skilled and semi-skilled workers as well as automated tasks. The number of subsystems that the Company manufacturers depends on the customers' needs and may range from a few subsystems (such as an optoelectronic sun sensor for use in a satellite) to many thousands (sensors used in laser printers and bar code readers). The principal raw materials and subcomponents used in producing the Company's optoelectronic devices and subsystems consist of silicon wafers, ceramics, electronic subcomponents, light emitting diodes, phototransistors, printed circuit boards, headers and caps, housings, cables, filters and packaging materials. For cost, quality control and efficiency reasons, the Company generally purchases raw materials and subcomponents only from single vendors with whom the Company has ongoing relationships. The Company does, however, qualify second sources for most of its raw materials and subcomponents, or has identified alternate sources of supply. The Company purchases the materials pursuant to purchase orders placed from time to time in the ordinary course of business. The silicon-based optoelectronic devices manufactured by the Company are critical components in most of its subsystems. Since 1987, the Company has purchased substantially all of the silicon wafers it uses to manufacture its optoelectronic devices from Wacker Siltronic Corp. Although to date the Company has not experienced any significant shortages or material delays in obtaining any of its raw materials or subcomponents, there can be no assurance that the Company will not face such shortages or delays in one or more of these materials in the future. Substantially all of the optoelectronic devices, subsystems, circuit boards and x-ray generators used in the Company's inspection and detection systems are manufactured in-house. The metal shells of the x-ray inspection systems, and certain standard mechanical parts are purchased from various third-party unaffiliated providers. Patents and Trademarks In 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 expires in September 2000. Subsequent to the end of the patent term, the Company will be free to use the technology without patent or license restriction. Under the license, for which the Company paid $450,000, the Company is permitted to make, use and sell or otherwise dispose of security and inspection products that use an x-ray line scan system for baggage inspection purposes covered by EG&G's patent. The license may require the Company to make additional, contingent royalty payments of up to $350,000 based on shipment of certain products which incorporate the licensed technology. 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, 13

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. Rapiscan Security Products utilize the trademarks Rapiscan(R) and SECURE(TM). SMI owns: U.S. Patent No. 5,812,047, expiring in 2017, pertaining to the manufacture of silicon pressure-sensor devices; U.S. Patent No. 6,089, 099, expiring in 2018, pertaining to method and application for forming a bonded silicon-glass pressure sensors; U.S. Patent No. 6,093,579, expiring in 2018, pertaining to low pressure sensors and the method of manufacture; and U.S. Patent No. 6,107,170, expiring in 2018, pertaining to silicon sensor contact with platinum silicide, titanium/tungsten and gold. SMI has other patent applications pending for various applications; it is unknown at this time if these patents will be issued. Metorex Security's "Metor" trademark is registered in 25 countries, including the United States, the European Union countries and Japan. Metorex Security has also registered the trademark "Metorscan" in the United States and the European Union countries. Metorex Security utilizes four patents registered in the United States (U.S. Patent Nos. 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. 6,058,151, 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 Company believes that the above patents and trademarks are important to the Company's business. The loss of some of these patents or trademarks might have a negative impact; however, the Company operates in a competitive environment with a known customer base and relies mainly on providing value for money with quality products and services to ensure continuing business. Environmental Regulations The Company is subject to various federal, state and local environmental laws, ordinances and regulations relating to the use, storage, handling, and disposal of certain hazardous substances and wastes used or generated in the manufacturing and assembly of the Company's products. Under such laws, the Company may become liable for the costs of removal or remediation of certain hazardous substances that have been or are being released on or in its facilities or that have been or are being disposed of off site as wastes. Such laws may impose liability without regard to whether the Company knew of, or caused, the release of such hazardous substances. In the past, the Company has conducted a Phase I environmental assessment report for each of the 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. 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 14

Company. There can be no assurance that the Company will be able to compete successfully against any current or future competitors in either the optoelectronic and silicon pressure-sensor devices and subsystems and medical imaging systems market or the security and inspection markets or that future competitive pressures will not materially and adversely affect its business, financial conditions and results of operations. In the optoelectronic and silicon pressure-sensors devices and subsystems market, competition for optoelectronic devices and subsystems is based primarily on such factors as expertise in the design and development of optoelectronic devices, product quality, timeliness of delivery, price, customer technical support, and on the ability to provide fully integrated services from application development and design through volume subsystem production. The Company believes that its major competitors in the optoelectronic device and subsystem market are 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 believes that it generally does not compete to any significant degree with any other large United States, European or Asian manufacturers of standard optoelectronic components. Competition for the Company's medical imaging products comes principally from Lunar Corporation, Hologic, Inc. and Norland Medical Systems, Inc. In the case of silicon pressure-sensors and microstructures, the Company bases much of its current competitive position on pressure sensor performance, particularly at low pressures, and process and manufacturing controls, particularly in the automotive areas. Customer support and design expertise are also very important. The Company believes that its primary silicon pressure-sensor competitors include IC Sensors Division of Measurement Specialties , Inc., Novasensor Division of Lucas Controls, Sensym ICT, and Motorola Semiconductor group. 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 and silicon pressure-sensor devices and subsystems, and medical imaging systems as well as its security and inspection products within one to three months after receiving an order. However, such shipments may be delayed for a variety of reasons including any special design or engineering requirements of the customer. In addition, large orders (more than ten machines) of security and inspection products typically require more lead time. 15

Large cargo scanning machines require six to thirty months lead time. The only significant shipping delays which the Company has experienced are with large cargo scanners. Such delays can occur for any of the following reasons: (i) additional time necessary to conduct large cargo inspections at the factory before shipment; (ii) the customer's needs to engage in timely special site preparation to accommodate such a scanner, and as to which the Company has no control or responsibility; and (iii) additional fine tuning of such scanners once they are installed. At June 30, 2000, the Company's backlog products totaled approximately $54.3 million, compared to approximately $44.1 million at June 30, 1999 and $46.9 million at June 30, 1998. Most of the Company's backlog as of June 30, 2000, with the exception of a majority of an order for large cargo-scanning machines valued at approximately $9 million, is expected to be shipped during the fiscal year ending June 30, 2001. Any failure of the Company to meet an agreed upon schedule could lead to the cancellation of the related order. Variations in the size of the order, the product mix, and delivery requirements of the customer order may result in substantial fluctuations in backlog from period to period. Backlog as of any particular date should not be relied upon as indicative of the Company's revenues for any future period and cannot be considered a meaningful indicator of the Company's performance on an annual or quarterly basis. Employees As of June 30, 2000, the Company employed approximately 995 people, of whom 720 were employed in manufacturing, 70 were employed in research and development, 85 were employed in finance and administration, 65 were employed in sales and marketing, and 55 were employed in its service organization. Of the total employees, approximately 497 were employed in the United States, 15 in Canada, 158 were employed in Europe, and 325 were employed in Asia, 22 employees at AME and 10 Metorex Security employees in Finland are members of a union and have collective bargaining rights. Other than the employees of AME and 10 Metorex Security employees in Finland, none of the Company's other employees is unionized. There has never been a work stoppage or strike at the Company, and management believes that its relations with its employees are good. 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, 2000, 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, engineering, sales and marketing and service 41,600 2006 Walnut, California Manufacturing, engineering, sales and marketing 6,350 2003 Ocean Springs, Mississippi Manufacturing, engineering and sales and marketing 41,800 2001 Fremont, California Manufacturing, engineering, sales and marketing and service 6,500 2001 Princeton, New Jersey Service and sales and marketing 2,900 2001 Georgetown, Canada Manufacturing, engineering, sales and marketing and service 22,000 2003 Johor Bahru, Malaysia Manufacturing and sales 15,700 2000 Johor Bahru, Malaysia Manufacturing 21,000 2001 16

The lease of the 15,700 square foot facility at Johor Bahru, Malaysia expired in August 2000. The Company is presently negotiating the renewal 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 In October 1994, UDT Sensors entered into a Consent Judgment and a Criminal Plea and Sentencing Agreement (collectively, the "Consent Agreements") with the United States of America. The charges contained in the Consent Agreements relate to high-reliability optoelectronic subsystems that UDT Sensors manufactured for use in military aircraft, attack helicopters and submarines. In the Consent Agreements, UDT Sensors agreed that it had not tested 100% of these products as required by the applicable military specifications. Under the terms of the Consent Agreements, UDT Sensors has paid a total of $1.5 million, plus interest, in five annual installments ending on March 31, 1999. UDT Sensors was placed on probation for the five-year period ending March 31, 2000 with respect to sales of optoelectronic subsystems for use by the U.S. Department of Defense. Probation does not, however, prohibit UDT Sensors from selling optoelectronic products to the United States, and UDT Sensors has, since the date of the Consent Agreements, continued to manufacture and sell the same optoelectronic, products for use in military aircraft, attack helicopters and submarines. In addition, in order to ensure that UDT Sensors complies with all Federal procurement laws, UDT Sensors agreed to implement programs and practices to establish and monitor complying contracting procedures, and agreed to file periodic reports evidencing such practices and programs. 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 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 have subjected them 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 Governor of California, the California Department of Corrections, its Director and other Department of Corrections personnel. The 17

complaint, 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. The Company is also involved in routine litigation from time to time in the course of conducting its business. ITEM 4. SUBMISSION ON MATTERS TO A VOTE OF SECURITY HOLDERS None. 18

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 and silicon pressure- sensor micro-structure technology. The Company designs and manufactures optoelectronic and silicon pressure-sensor devices and value-added subsystems for OEMs for use 21

in a broad range of applications, including security, medical diagnostics, telecommunications, gaming, office automation, aerospace, computer peripherals and industrial automation. In addition, the Company utilizes its optoelectronic technology and design capabilities to manufacture security and inspection products that it markets worldwide to end users under the "Rapiscan," "Secure" and "Metor" brand names. These products are used to inspect people, baggage, cargo and other objects for weapons, explosives, drugs and other contraband. The Company has also, through the acquisition of Osteometer, expanded into the manufacture and sale of bone densitometers, which are used to provide bone loss measurements in the diagnosis of osteoporosis. In fiscal 2000, revenues from the sale of optoelectronic and silicon pressure-sensor devices and subsystems and medical imaging systems amounted to $63.8 million, or approximately 57.5% of the Company's revenues, while revenues from sales of security and inspection products amounted to $47.1 million, or approximately 42.5% of the Company's revenues. The Company was organized in May 1987. The Company's initial products were optoelectronic devices and subsystems sold to customers for use in the manufacture of x-ray scanners for carry-on airline baggage. In December 1987, the Company formed Opto Sensors (Singapore) Pte Ltd. ("OSI Singapore") to manufacture optoelectronic devices and subsystems. In April 1990, the Company acquired UDT 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. The osteoporosis device industry is currently weak and is expected to remain so for at least the near-term. In January 1994, the Company entered into a joint venture agreement with Electronics Corporation of India, Limited ("ECIL"), an unaffiliated Indian corporation, pursuant to which the Company and ECIL formed ECIL Rapiscan. The joint venture was established for the purpose of manufacturing security and inspection products in India from kits sold to ECIL by the Company. The Company currently owns a 36.0% interest in ECIL Rapiscan. In August 1998, the Company invested $315,000, including professional fees associated with the acquisition, in Square One for an equity share of approximately 16%, and in August 2000, the Company acquired substantially all of its assets and returned the stock it had previously held in Square One. 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. With this additional equity investment, the Company increased its equity share in OSI Medical to approximately 56%. 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 are first exercisable commencing on April 12, 2001, and, if fully exercised, would result in the Company's share in OSI Medical being increased to over 60%, based upon the number of shares presently outstanding. Also, pursuant to the OSI Medical Agreement, under certain circumstances 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. The designs and processes of SMI allow leveraging of the Company's silicon wafer fabrication technologies to initially serve pressure sensor markets and extend into the future to a variety of products based on mechanical structures in silicon. 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 and silicon pressure-sensor devices and subsystems, and medical imaging systems, at its facilities in Hawthorne and Fremont, California, Ocean Springs, Mississippi; Johor Bahru, Malaysia; 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, 2000, the Company marketed its products worldwide through approximately 65 sales and marketing employees located in seven countries, and through approximately 180 independent sales representatives. Revenues from shipments made outside of the United States accounted for 49.4%, 48.5% and 55.8% of revenues for the fiscal years 1998, 1999 and 2000, respectively. Information regarding the Company's operating income or loss and identifiable assets attributable to each of the Company's geographic areas is set forth in Note 15 in the Company's Consolidated Financial Statements. The effective income tax rate 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. However, 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. The initial purchase under the contract is for 100 carry-on baggage x- ray screening systems. 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 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 Company recognizes revenues upon shipment. As the Company's product offerings change to include sales of significantly larger systems, such as cargo inspection products, the Company may adopt the percentage of completion method of revenue recognition for certain products. 23

Results of Operations The following table sets forth certain income and expenditure items as a percentage of total revenues for the periods indicated.

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 acqusition 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 24

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. 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 a 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 25

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. Comparison of Fiscal Year Ended June 30, 1999 to Fiscal Year Ended June 30, 1998 Revenues. Revenues consist of sales of optoelectronic and silicon pressure sensor devices, subsystems and medical imaging systems as well as security and inspection products. Revenues are recorded net of inter-company eliminations. Revenues for the fiscal year ended June 30, 1999, increased by $7.8 million or 8.4% to $101.8 million from $93.9 million for the fiscal year ended June 30, 1998. Revenues for the sale of optoelectronics and silicon pressure sensor devices, subsystems and medical imaging systems, net of intercompany eliminations, increased by $5.4 million, or 10.7% to $55.5 million from $50.1 million for fiscal 1998. The increase was primarily due to an increase in sales to the oil exploration industry and sales of medical imaging systems and silicon pressure sensors through the acquisitions of Osteometer and SMI, respectively. Due to the worldwide decline in the oil exploration business, the Company expects declines in shipments to the oil exploration industry in the foreseeable future. Revenues from the sale of security and inspection products increased $2.5 million, or 5.7% to $46.3 million from $43.8 million for fiscal 1998. The increase in revenues from the sale of security and inspection products was primarily due to an increase in walk through metal detection systems through the acquisition of Metorex Security, which was offset in part by decrease in revenues due to weakness in the security and inspection products market. Gross Profit. Cost of goods sold consist of material, labor and manufacturing overhead. Gross profit increased by $2.2 million, or 8.0%, to $29.1 million from $27.0 million for fiscal 1998. As a percent of revenues, gross profit decreased to 28.6% in fiscal 1999 from 28.7% in fiscal 1998. The increase in gross profit was due to increased sales, change in product mix and increased efficiencies in manufacturing. Selling, General and Administrative. Selling, general and administrative expenses consist primarily of compensation paid to sales, marketing, and administrative personnel, professional service fees and marketing expenses. For the year ended June 30, 1999, such expenses increased by $5.0 million, or 39.9%, to $17.7 million from $12.7 million in fiscal 1998. As a percentage of revenues, selling, general and administrative expenses increased to 17.4% in fiscal 1999 from 13.5% in fiscal 1998. The increase in expenses was due primarily to the inclusion of selling, general and administrative expenses of recent acquisitions in the Company's consolidated financial statements, exchange rate fluctuation losses due to currency translation relating to the relatively strong U.S. dollar compared to European currencies and an increase in marketing expenses to penetrate new markets for the Company's existing products and was offset in part by the proceeds from the settlement of certain material litigation. For the year ended June 30, 1999, $4.5 million of selling, general and administrative expenses of recent acquisitions were included in the Company's consolidated financial statements. The exchange rate losses for fiscal 1999 were $743,000 compared to $39,000 for fiscal 1998. Research and Development. Research and development expenses include research related to new product development and product enhancement expenditures. For the year ended June 30, 1999, such expenses increased by $1.9 million, or 50.7% to $5.7 million from $3.8 million in fiscal 1998. As a percentage of revenues, research and development expenses increases to 5.6% in fiscal 1999 from 4.0% in fiscal 1998. The increase in expenses was primarily due to the increase in personnel cost resulting from the recent acquisitions. For the year ended June 30, 1999, $1.8 million of research and development expenses incurred by the acquired companies were included in the Company's consolidated financial statements. 26

Goodwill Amortization. Amortization of goodwill increased to $595,000 in fiscal 1999 from $106,000 in fiscal 1998. The increase in amortization expense was primarily due to amortization of goodwill associated with the acquisition of Osteometer, Metorex Security and SMI. In the prior years, goodwill amortization was included as a component of selling, general and administrative expenses. Asset Impairment Charge. The asset impairment charge relates to the closure of the operations of Osteometer in Denmark. For the year ended June 30, 1999, the asset impairment charge was $4.0 million, which includes the write off of $3.7 million of goodwill and $250,000 of other assets. Some of these operations may be relocated to the United States over the next several months. The Company expects to incur additional expenses in connection with the discontinuation of those operations and their relocation to the United States, which will be recorded in the future periods. In Process Research and Development. The Company used a total of $15.3 million for the acquisitions of Osteometer, Metorex Security and SMI, including professional fees associated with these acquisitions. Out of the total of $15.3 million, the company incurred an aggregate of $2.6 million in in-process research and development charges in fiscal 1999, related to these acquisitions. In September 1998, the Company acquired the assets, including the developmental technology, and assumed the liabilities of Osteometer. The Company paid $7.9 million in cash, including professional fees associated with the acquisition. In November 1998, the Company acquired the assets, including developmental technology, of Metorex Security. The Company paid $4.7 million in cash, including professional fees associated with the acquisition, and in July 1999, the Company paid $4.4 million Finnish markka (approximately $739,000), in lieu of contingent payments up to $1.5 million, based on future sales. Also in November 1998, the Company acquired the assets, including the developmental technology, of SMI. The Company paid $2.7 million in cash, including professional fees associated with the acquisition. Based on the valuations, the Company allocated the excess of the non- contingent purchase price over the fair value of net tangible assets acquired to goodwill and identified intangible assets. In performing this allocation, the Company considered, among other factors, the attrition rate of the active users of the technology at the date of acquisition and the research and development projects in process at the date of acquisition. With regard to the in-process research and development projects, the Company considered, among other factors, the stage of development of each project at the time of acquisition, the importance of each project to the overall development plan, and the projected incremental cash flows from the projects when completed and any associated risks. Associated risks include the inherent difficulties and uncertainties in completing each project and thereby achieving technological feasibility and risks related to the impact of potential changes in future target markets. As of June 30,1999, with the exception of Osteometer, the above mentioned research and development projects were progressing as planned. Restructuring Costs. During fiscal 1999, the Company adopted a restructuring plan to consolidate certain subsidiaries and, in connection therewith, the Company recorded a non-recurring expense of $458,000. These costs were associated primarily with the termination of certain employees, in the amount of $395,000, and consolidation of certain subsidiaries, in the amount of $63,000. All of the restructuring costs were incurred and recorded before March 31, 1999. Income (loss) from operations. For the year ended June 30, 1999, loss from operations was $1.9 million compared to income of $10.4 million in fiscal 1998. Excluding, the non-recurring asset impairment charge, in process research and development and restructuring costs of $7.0 million, income from operations for the year ended June 30, 1999 decreased by $5.3 million or 50.9%, to $5.1 million from $10.4 million in fiscal 1998. Income from operations decreased due to increased selling, general and administrative expenses, increased research and development expenses and increased goodwill amortization and was partially offset by increased gross profit. Interest expense (income). For the year ended June 30, 1999, the Company earned net interest income of $102,000 compared to net interest income of $600,000 for fiscal 1998. The reduction in net interest income was 27

due to increased borrowing on the Company's lines of credit and a reduction in short term investments used for working capital and acquisitions. Provision (benefit) for income taxes. For the year ended June 30, 1999, the Company had an income tax benefit of $2.6 million compared to provision for income taxes of $2.7 million for fiscal 1998. Excluding, the non-recurring asset impairment charge, in process research and development and restructuring costs, provision for income taxes for the year ended June 30, 1999, was $1.1 million, compared to $2.8 million for fiscal 1998 and as a percentage of income before provision for income taxes, provision for income taxes was 16.5% for the year ended June 30, 1999 compared to 25.0% for fiscal 1998. The reduction in the Company's effective tax rate was primarily due to a mix in income from U.S. and foreign operations, utilization of previously unrealized foreign net operating losses and a one year tax holiday in Malaysia for fiscal year ended June 30, 1999. Net Income. For the reasons outlined above, including the non-recurring asset impairment charge, in process research and development and restructuring costs, for the year ended June 30, 1999, the Company had a net income of $741,000, compared to $8.2 million for fiscal 1998. Excluding, the non- recurring asset impairment charge, in process research and development and restructuring costs of $8.2 million ($4.7 million of net of taxes), net income for the year ended June 30, 1999 decreased 35.2% to $5.3 million, compared to $8.2 million for fiscal 1998. 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, 2000, the Company's principal source of liquidity consisted of $10.9 million in cash and several credit agreements described below. The Company's operations used net cash of $902,000 during fiscal 2000, compare to net cash provided of $80,000 in fiscal 1999. The amount of net cash used by operations reflects increases in accounts receivable and inventory and reductions in advances from customers, accrued warranty and other accrued expenses and current liabilities. Net cash used in operations was offset in part by an increase in accounts payable, income taxes payable, and reduction in income taxes receivable. The increase in accounts receivable is mainly due to the increased sales, timing of shipments and increase in inventory is due to increase in shipments and product mix. Net cash used in investing activities was $1.3 million and $23.4 million for fiscal 2000 and 1999, respectively. In fiscal 2000, 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. In fiscal 1999, the net cash used in investing activities reflects primarily cash used in business acquisitions, cash used in equity investments, the purchase of property and equipment, and purchase of marketable securities. Net cash provided by financing activities was $5.7 million and $7.5 million for fiscal 2000 and 1999, respectively. In fiscal 2000, net cash provided by financing activities resulted primarily from borrowings under the Company's term loan was offset in part by the purchase of treasury stock and repayment of working capital lines of credit. In October 1999, the Company borrowed $3.0 million from its term loan facility with Sanwa Bank. The term loan amortizes over seven years and is payable monthly over five years. The balance is due in one balloon payment after five years. In November 1999, the Company converted $8.5 million of borrowings from its acquisition line of credit to a term loan, for a period of 48 months. In fiscal 1999, net cash provided by financing activities resulted primarily from the Company's working capital lines of credit and was partially offset by payment of long term debt and purchase of treasury stock. In March 1999, the Company announced a stock repurchase program of up to 2,000,000 shares of its common stock. Through September 27, 2000, the Company repurchased 490,500 shares at an average price $4.60 28

per share. The stock repurchase program did not have a material effect on the Company's liquidity and is not expected to have a material effect on liquidity in subsequent quarters. The Company anticipates that current cash balances, anticipated cash flows from operations and current borrowing arrangements will be sufficient to meet its working capital and capital expenditure needs for the foreseeable future. In January 1997, the Company and its U.S. subsidiaries entered into a credit agreement with Sanwa Bank California. The agreement, as amended and restated in September 1999, provides for a $10.0 million line of credit, which includes revolving line, letter of credit, acceptance and foreign exchange facilities. In addition, the Company has a $3.0 million equipment line of credit for capital purchases, a $3.0 million term loan and a $15.0 million line of credit for acquisitions with certain restrictions. Advances under the lines of credit bear interest at a rate equal to a variable bank reference rate (9.5% at June 30, 2000) or, at the Company's option, at a fixed rate as quoted by the bank upon request for specific advances. As of June 30, 2000 there was $5.4 million outstanding under the line of credit, $7.4 million was outstanding under the acquisition line of credit, $2.8 million outstanding under the term loan and no amount was outstanding under the equipment line of credit. As of June 30, 2000, $630,000 was outstanding under letters of credit. The lines expire in November 2000. Borrowings under the agreement are secured by liens on substantially all of the assets of the Company's U.S. subsidiaries. The agreement restricts the borrowers from incurring certain additional indebtedness and from making capital expenditures greater than $5.0 million on a consolidated basis (excluding assets acquired through acquisition) in any fiscal year, except for the purchase of real property to be occupied by the borrowers. In addition, the credit agreement contains certain covenants. Among these, the Company is at all times required to maintain (on a consolidated basis) a tangible net worth of at least $50.0 million; a ratio of debt to tangible net worth of not more than 3.0 to 1; a ratio of cash, cash equivalents and accounts receivable to current liabilities of not less than 0.8 to 1; and a debt coverage ratio of 2.0 to 1. The Company was in violation of a covenant for the quarter ended June 30, 2000, which was subsequently waived by the bank. The Company and three of its U.S. subsidiaries entered into an agreement with Wells Fargo HSBC Trade Bank, N.A. The agreement has been renewed periodically, and in February 2000 it was extended until May 31, 2001. As currently in effect, the agreement provides for letters of credit for a specific customer up to $250,000. As of June 30, 2000, there was outstanding approximately $250,000 for standby letters of credit. Borrowings under the agreement are secured by liens on certain of the Company's assets. Covenants in connection with the agreement impose restrictions and requirements related to, among other things, maintenance of certain financial ratios, limitations on outside indebtedness, profitability, payments of dividends and capital expenditures. Rapiscan U.K. has a loan agreement with Midland Bank plc, which provides for an overdraft facility up to a maximum amount of 2.0 million Pounds Sterling (approximately $3.0 million at June 30, 2000) outstanding at any one time, which amounts are secured by certain assets of Rapiscan U.K. At June 30, 2000, no amounts were outstanding under the overdraft facility. Outstanding borrowings bear interest at a base rate (6% at June 30, 2000) plus 1.5% per annum. The agreement also provides for a 1.0 million Pounds Sterling (approximately $1.5 million at June 30, 2000) facility for tender and performance bonds and a 1.0 million Pounds Sterling (approximately $1.5 million at June 30, 2000) facility for the purchase of forward exchange contracts. These facilities are secured by certain assets of Rapiscan U.K. and the Company has guaranteed Rapiscan U.K.'s obligations under the performance bond facility. As of June 30, 2000, $785,000 was outstanding under the performance bond facility and Rapiscan U.K. had purchased forward exchange contracts in the amount of $1,000. The above facilities expire in January 2001 and the Company believes that they will be renewed on the same or similar terms. OSI Singapore has a loan agreement with Indian Bank (Singapore), which provides for an accounts receivable discounting facility for borrowing of up to 2.9 million Singapore dollars (approximately $1.7 million at June 30, 2000). Borrowings under the line of credit bear interest at the bank's prime rate (9.5% at June 30, 2000) plus 2.25%. The line of credit is terminable at any time. As of June 30, 2000 there were no amounts outstanding under the line of credit. Borrowings under the line of credit are collateralized by certain assets of 29

OSI Singapore and are guaranteed by certain officers of the Company. Borrowings secured by intercompany receivables are guaranteed by the Company. AME has a loan agreement with Christiania Bank OG Kreditkasse which provides for a revolving line of credit for borrowings of up to 10.0 million Norwegian kroner (approximately $1.2 million at June 30, 2000). As of June 30, 2000, no amounts were outstanding under this line of credit. Borrowings under the line of credit bear interest at a variable rate, which was 8.0% at June 30, 2000. OSI Malaysia has a loan agreement with the Hong Kong Bank Malaysia Berhad, which provides for a bank guarantee line of credit for 2.5 million Malaysia ringgits (approximately $658,000 at June 30, 2000) for performance bonds and a 1.0 million Malaysian ringgits overdraft facility (approximately $263,000 at June 30, 2000). Borrowings under the overdraft facility bear interest at the bank's base lending rate (6.8% at June 30, 2000) plus 1.75%. At June 30, 2000, the amount outstanding under the performance bond facility was $310,000 and there were no amounts outstanding under the overdraft facility. Borrowings under this agreement are secured by certain assets of OSI Malaysia. These lines expire in October 2000 and the Company believes that they will be renewed on the same or similar terms. OSI Malaysia has a loan agreement with Bank Utama, which provides for a revolving line of credit of up to an amount of 1.5 million Malaysian ringgits (approximately $395,000 as of June 30, 2000). Borrowings under the line of credit bear interest at the bank's base lending rate (6.8% at June 30, 2000) plus 2.25%. As of June 30, 2000,1.4 million Malaysian ringgits (approximately $384,000 at June 30, 2000) were outstanding under this line of credit. Borrowings under this agreement are secured by certain assets of OSI Malaysia and are guaranteed by the Company. The line of credit expired in February 2000 and the Company is operating the line on a month-to-month basis. The Company believes that it will be renewed on the same or similar terms. Metorex Security has a loan agreement with a Finnish bank that provides for a foreign currency overdraft facility up to 3.0 million Finnish markka (approximately $483,000 at June 30, 2000). At June 30, 2000, approximately $331,000 was outstanding under the overdraft facility. The agreement also provides for 1.0 million Finnish Marks (approximately $161,000 at June 30, 2000) for tender and performance bonds. At June 30, 2000 approximately $123,000 was outstanding under the tender and performance bonds facility. Borrowings under these facilities bear interest rate at the bank's prime lending rate (4.5% at June 30, 2000) plus 0.75%. The above facilities expire in February 2001, 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 In June 1999, the financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 137, Accounting for Derivative Instruments and Hedging Activities-Deferral of the Effective Date of FASB Statement No. 133 (an amendment of FASB Statement No. 133). Under the provisions of this Statement, the effective date of Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities ("SFAS No. 133"), is deferred to fiscal years beginning after June 15, 2000. The Company is currently evaluating the impact of adopting SFAS No. 133, and does not expect it to have a material impact on the Company's financial statements or results of operations. In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin 101, Revenue Recognition in Financial Statements ("SAB 101"). SAB 101 provides guidance on applying generally accepted accounting principles to revenue recognition in financial statements. The Company will adopt SAB 101 as required in the first quarter of fiscal 2001. The Company is currently evaluating the impact of adopting SAB 101, and does not expect it to have a material impact on the Company's financial statements or results of operations. 30

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS Foreign Currency Translation 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 $743,000 and $156,000 were included in income for fiscal 1999 and 2000, respectively. Importance of International Markets International markets provide the Company with significant growth opportunities. However, the following events, among others, could adversely affect the Company's financial results in subsequent periods: periodic economic downturns in different regions of the world, changes in trade policies or tariffs, and political instability. For the year ended June 30, 2000, overall foreign currency fluctuations relative to the U.S. dollar had an immaterial effect on the Company's consolidated revenues and results of operations. As a result of changes in monetary policy in Malaysia, including the pegging of the Malaysian ringgit to the U.S. dollar, the Company believes that its foreign currency exposure in Malaysia will not be significant in the foreseeable future. The Company continues to perform ongoing credit evaluations of its customers' financial condition and, if deemed necessary, the Company requires advance payments for sales. The Company is monitoring economic and currency conditions around the world to evaluate whether there may be any significant effect on its international sales in the future. 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. Interest Rate Risks 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. We do not use derivative instruments to hedge our interest rate risk. The carrying amount, principal maturity and estimated value of our investment portfolio and long-term debt exposure as of June 30, 1999 are as follows: Carrying Amount Maturity -------- -------------------------- Fair 1999 2000 2001 2002 2003 2004 Value -------- ---- ---- ---- ---- ---- ------ Investments Cash and cash equivalents.......... $ 7,241 -- -- -- -- -- $7,241 Average interest rate.............. 4.49% -- -- -- -- -- -- Long-Term Debt Secured long term loan............. 409 292 117 -- -- -- 409 Average interest rate.............. 9.0% 9.0% 9.0% 31

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% 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. The Company from time to time enters into foreign currency forward contracts to hedge certain foreign currency transactions and commitments. These contracts were not significant at June 30, 2000 and had a fair value of approximately $508,000, which closely approximates their carrying value at June 30, 2000. ITEM 8.

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, 2000 and 1999, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2000 in conformity with accounting principles generally accepted in the United States of America.

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Years Ended June 30, 1998, 1999, and 2000 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES General--OSI Systems, Inc. (formerly Opto Sensors, Inc.) and its subsidiaries (collectively, the "Company") is a vertically integrated, worldwide provider of devices, subsystems, and end-products based on optoelectronic and silicon pressure-sensor microstructure technology. The Company designs and manufactures optoelectronic and pressure-sensor devices and value-added subsystems for original equipment manufacturers ("OEMs") in a broad range of applications, including security, medical diagnostics, 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. 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 a maturity of three months or less to be cash equivalents. Investment Securities--The Company's investment securities are composed of equity securities that have been classified as available-for-sale securities. The equity securities are carried at their fair market value based upon the quoted market prices of those investments. Unrealized gains and losses on equity securities are included in accumulated other comprehensive income. During the year ended June 30, 2000, the Company sold the investments for a gain of $309,000. Concentrations of Credit Risk--Financial instruments that potentially subject the Company to credit risk consist primarily of cash, cash equivalents, and accounts receivable. At June 30, 2000, approximately 58 percent of the Company's cash and cash equivalents were held at one financial institution. The Company performs ongoing credit valuations of its customers' financial condition and provides an allowance for potential credit losses. Inventory--Inventory is stated at the lower of cost or market; cost is determined on the first-in, first-out method. Inventory at June 30, 1999 and 2000 consisted of the following (in thousands): 1999 2000 ------- ------- Raw materials................................................ $11,963 $16,877 Work-in-process.............................................. 8,000 6,619 Finished goods............................................... 4,518 7,424 ------- ------- Total...................................................... $24,481 $30,920 ======= ======= 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. F-7

After technological feasibility is F-8

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Years Ended June 30, 1998, 1999, and 2000 established, certain software development costs are capitalized. The software, once developed, is a component that is included in x-ray security machines when they are sold to customers. The Company amortizes these costs on a straight-line basis over a two to five year period, once it is put into use. No software development costs were capitalized during the three years ended June 30, 2000. 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, 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. Foreign Exchange Instruments--The Company's use of derivatives is limited to the purchase of foreign exchange contracts in order to attempt to reduce foreign exchange transaction gains and losses. The Company purchases forward contracts to hedge commitments to acquire inventory for sale and does not use the contracts for trading purposes. As of June 30, 2000, there was approximately $508,000 in outstanding foreign exchange contracts. The estimated fair value of these contracts, based on quoted market prices from banks, closely approximated their carrying value at June 30, 2000. Revenue Recognition--The Company recognizes revenue upon shipment of its products. Concurrent with the shipment of the product the Company accrues estimated product return reserves and warranty expenses. 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, Norwegian kroner, Finnish markka, Canadian dollars, and U.K. pounds sterling, respectively. Foreign currency financial statements are translated into U.S. dollars at current rates, with the exception of revenues, costs, and expenses, which are translated at average rates during the reporting period. Gains and losses resulting from foreign currency transactions are included in income, while those resulting from translation of financial statements are excluded from income and accumulated as a component of accumulated other comprehensive income. Transaction losses of approximately $39,000, $743,000, and $156,000 were included in income for the years ended June 30, 1998, 1999 and 2000, 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 F-9

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Years Ended June 30, 1998, 1999, and 2000 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. Of that amount, $52,000 was unpaid at June 30, 2000, and is included in other accrued expenses. Based on current estimates, the Company anticipates that the current restructuring accruals approximate the ultimate restructuring unpaid amounts. Earnings per Share--The Company has adopted Statement of Financial Accounting Standards ("SFAS") No. 128 "Earnings per Share." The Company has reflected the provisions of SFAS No. 128 in the accompanying financial statements for all periods presented. Earnings per common share are computed using the weighted-average number of shares outstanding during the period. Earnings per common share--assuming dilution are computed using the weighted- average number of shares outstanding during the period and dilutive common stock equivalents from the Company's stock option plans, calculated using the treasury stock method. The following table reconciles the numerator and denominator used in calculating earnings per share and earnings per common share--assuming dilution.

SAB 101 provides guidance on applying generally accepted accounting principles to revenue recognition in financial statements. The Company will adopt SAB 101 as required in the first quarter of fiscal 2001. The Company is currently evaluating the impact of adopting SAB 101, and does not expect it to have a material impact on the Company's financial position or result of operations. Use of Estimates--The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Reclassifications--Certain reclassifications have been made to prior-year amounts to conform to the current year's presentation. 2. JOINT VENTURES AND EQUITY INVESTMENTS In January 1995, the Company, together with an unrelated company, formed ECIL-Rapiscan Security Products Limited, a joint venture organized under the laws of India.

The Company changed the method of accounting for OSI Medical from the equity to the purchase method of accounting in October 1999. During April 2000, the Company also received 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 are first exercisable commencing on April 12, 2001.

The estimated fair value of options granted during 1998, 1999, and 2000 pursuant to SFAS No. 123 was approximately $768,000, $1,272,000, and $867,000 respectively. Had the Company adopted SFAS No. 123, pro forma net income (loss) would have been $7,787,000, $(213,000), and $23,000, and pro forma net income (loss) per share would have been $0.87, $(0.02), and $0.00 for 1998, 1999, and 2000, 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 109 percent in fiscal 2000 (1999 and 1998, 71 percent and 44 percent, respectively), a risk-free interest rate of 6.39 percent in fiscal 2000 (1999 and 1998, 5.67 percent and 5.47 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.

OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Years Ended June 30, 1998, 1999 and 2000 A participant may elect to withdraw from the 1999 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. No shares of common stock were purchased under the Plan for the year ended June 30, 1999. The Company's liability to the Plan was $36,000 and $23,000 at July 30, 1999 and 2000, respectively. 10. SHAREHOLDERS' EQUITY The Company's Registration Statement for its initial public offering of securities (File No. 333-29179) became effective on October 1, 1997, when the Company issued 3,330,000 shares of its common stock for net proceeds of approximately $41,000,000. In March 1999, the board of directors instituted a treasury stock program under which the Company is authorized to purchase up to a total of 2,000,000 shares. The Company purchased 85,000 shares at a cost of $438,000 during fiscal 1999, and an additional 405,500 shares for $1,820,000 during fiscal 2000. During fiscal 2000, the Company retired the treasury shares. The shares 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.

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, 2000, 1999 and 1998. During 1995, a subsidiary in the U.K. (Rapiscan U.K.) transferred its existing employees from their former owner's plan to a new plan, the Rapiscan U.K. Defined Benefit Plan, which covers certain Rapiscan U.K. employees. The benefits under this plan are based on years of service and the employees' highest 12 months' compensation during the last five years of employment. Rapiscan U.K.'s funding policy is to make the minimum annual contributions required by applicable regulations based on an independent actuarial valuation sufficient to provide for benefits accruing after that date. Pension expense for the years ended June 30, 2000, 1999, and 1998 was approximately $125,000, $138,000, and $106,000, respectively.

SUBSEQUENT EVENTS On July 31, 2000, the board of directors declared a dividend distribution of one preferred share purchase right on each outstanding share of its common stock. The rights will be exercisable only if a person or group acquires 20 percent or more of OSI Systems, Inc.'s common stock or announces a tender offer, the consummation of which would result in ownership by a person or group of 20 percent or more of the common stock. Each right will entitle shareholders to buy one one-thousandth of a share of a new series of participating preferred stock at an exercise price of $100. If a person or group acquires 20 percent or more of OSI Systems, Inc.'s outstanding common stock, each right will entitle its holder (other than such person or members of such group) to purchase, at the right's then-current exercise price, a number of the Company's common shares having a market value of twice such price. In addition, if OSI Systems, Inc. is acquired in a merger or other business-combination transactions after a person has acquired 20 percent or more of the Company's outstanding common stock, each right will entitle its holder to purchase, at the right's then-current exercise price, a number of the acquiring company's common shares having a market value of twice such price. The acquiring person will not be entitled to exercise these rights. Prior to the acquisition by a person or group of beneficial ownership of 20 percent or more of the Company's common stock, the rights are redeemable for $.001 per right at the option of the board of directors.

Exhibit 10.23 EMPLOYMENT AGREEMENT -------------------- THIS EMPLOYMENT AGREEMENT ("Agreement") is made and entered into this 1st day of September, 2000, by and between OSI SYSTEMS, INC. ("Company"), a California corporation, and AJAY MEHRA ("Employee"), with reference to the following facts: A. Employee has been serving Company as Chief Financial Officer in a satisfactory and capable manner pursuant to an oral agreement between Employee and Company. B. Company has requested that Employee enter into a written employment agreement with Company with respect to matters relating to continued employment with Company, and Employee has agreed to do so, upon the terms and conditions set forth herein. NOW, THEREFORE, in consideration of the terms and conditions and the mutual agreements and covenants set forth herein, the parties hereto agree as follows: 1. SCOPE OF EMPLOYMENT. ------------------- 1.1 Capacity. Company hereby continues to employ Employee and -------- Employee hereby accepts continued employment as Chief Financial Officer of Company. Employee shall report to the Chief Executive Officer of Company and perform the services and duties customarily incident to such office and as otherwise decided upon by the Chief Executive Officer or the Board of Directors. 1.2 Devotion of Services. Employee shall devote his entire -------------------- productive time, ability and attention exclusively to the business of Company during the term of this Agreement, except for passive investments, charitable and non-profit enterprises and any other business investments which do not interfere with his duties hereunder and which are not competitive with Employer's activities (except as the owner of less than 2% of the issued and outstanding capital stock of a publicly traded corporation). Employee shall perform and discharge well and faithfully those duties assigned him by Company. Employee shall perform his services under this Agreement in Los Angeles County, California, or such other location as is acceptable to Employee. 2. TERM. Subject to Section 6 herein, the term of this Agreement ---- shall commence as of the date of this Agreement and shall continue and remain in full force and effect for a period of three (3) years. However, in the event that Company thereafter continues to employ Employee, this Agreement shall be deemed automatically renewed upon the same terms and conditions set forth herein except (a) that the parties may mutually agree to revise any of the terms

set forth herein, and (b) the employment relationship will be on an "at will" basis, which means that, subject to Section 6.4 herein, either Company or Employee may elect to terminate the employment relationship at any time for any reason whatsoever, with or without cause. Employee acknowledges that no representation has been made by Company as to any minimum or specified term or length of employment following the term set forth above. 3. COMPENSATION. ------------ 3.1 Salary and Bonus. In consideration of the services to be ---------------- rendered by Employee hereunder, including without limitation any services rendered as an officer or director of Company or any subsidiary or affiliate thereof, during the term of this Agreement Company shall pay to Employee the following: (a) A salary in the amount of $260,000.00 per annum, which salary shall be reviewed no less frequent than annually by the Company. The Company may increase Employee's salary but, in no event, may Employee's salary be reduced during the term of this Agreement. (b) The Company presently intends to continue its policy of establishing a fiscal year end bonus pool for members of management of Company and/or its subsidiaries, which may be up to ten percent (10%) of the Company's net income before taxes. At the sole discretion of the Board of Directors, Employee may be entitled to participate therein. (c) All payments to Employee shall be subject to the regular withholding requirements of all appropriate governmental taxing authorities. (d) If the Company's Board of Directors and/or any committee thereof grants options to senior members of management of the Company and/or its subsidiaries, the Board of Directors and/or such committee shall consider in good faith granting a reasonable amount of options to Employee. 3.2 Other Benefits. Employee shall be entitled to participate in -------------- any medical and insurance plan which Company is presently providing or may provide to its senior executives. Employee acknowledges that the terms of such plans may change from time to time. Furthermore, Employee shall be entitled to receive the same automobile, life insurance policy and all other benefits which he presently is receiving. 3.3 Expenses. Company will advance to or reimburse Employee for -------- all reasonable travel and entertainment required by Company and other reasonable expenses incurred by Employee in connection with the performance of his services under this 2

Agreement in accordance with Company policy as established from time to time. 4. INVENTIONS. ---------- 4.1 Right to Inventions. Employee agrees that any discoveries, ------------------- inventions or improvements of whatever nature (collectively "Inventions") made or conceived by Employee, solely or jointly with others, during the term of his employment with Company, that are made with Company's equipment, supplies, facilities, trade secrets or time; or that relate, at the time of conception of or reduction to practice, to the business of Company or Company's actual or demonstrably anticipated research or development; or that result from any work performed by Employee for Company, shall belong to Company. Employee also agrees that Company shall have the right to keep any such Inventions as trade secrets, if Company so chooses. In order to permit Company to claim rights to which it may be entitled, Employee agrees to disclose to Company in confidence all Inventions that Employee makes during the course of his employment and all patent applications filed by Employee within three (3) years after termination of his employment. Employee shall (a) assist Company in obtaining patents on all Inventions deemed patentable by Company in the United States and in all foreign countries and (b) execute all documents and do all things necessary to obtain letters patent to vest Company with full and extensive titles thereto and to protect the same against infringement by others. For the purposes of this Agreement, an Invention is deemed to have been made during the period of Employee's employment if the Invention was conceived or first actually reduced to practice during that period, and Employee agrees that any patent application filed within three (3) years after termination of his employment with the Company shall be presumed to relate to an Invention made during the term of Employee's employment unless Employee can provide evidence to the contrary. 4.2 Assignment of Inventions and Patents. In furtherance of, and ------------------------------------ not in contravention, limitation and/or in place of, the provisions of Section 4.1 above, Company hereby notifies Employee of California Labor Code Section 2870, which provides: "Any provision in an employment agreement which provides that an employee shall assign or offer to assign any of his or her rights in an invention to his or her employer shall not apply to an invention for which no equipment, supplies, facility, or trade secret information of the employer was used and which was developed entirely on the employee's own time, and (a) which does not relate (1) directly or indirectly to the business of the employer or (2) to the employer's actual 3

or demonstrably anticipated research or development, or (b) which does not result from any work performed by the employee for the employer. Any provision which purports to apply to such an invention is to that extent against the public policy of this state and is to that extent void and unenforceable." Employee acknowledges that he has been notified by the Company of this law, and understands that this Agreement does not apply to Inventions which are otherwise fully protected under the provisions of said Labor Code Section 2870. Therefore, Employee agrees to promptly disclose in writing to the Company all Inventions, whether Employee personally considers them patentable or not, which Employee alone, or with others, conceives or makes during his employment with Company or as is otherwise required and set forth under Section 4.1 above. Company shall hold said information in strict confidence to determine the applicability of California Labor Code Section 2870 to said Invention and, to the extent said Section 2870 does not apply, Employee hereby assigns and agrees to assign all his right, title and interest in and to those Inventions which relate to business of the Company and Employee agrees not to disclose any of these Inventions to others without the prior written express consent of Company. Employee agrees to notify Company in writing prior to making any disclosure or performing any work during the term of his employment with Company which may conflict with any proprietary rights or technical know-how claimed by Employee as his property. In the event Employee fails to give Company notice of such conflict, Employee agrees that Employee shall have no further right or claim with respect to any such conflicting proprietary rights or technical know-how. 5. CONFIDENTIALITY. --------------- 5.1 Restrictions on Use of Trade Secrets and Records. During the ------------------------------------------------ term of his employment, Employee will have access to and become acquainted with various trade secrets of Company, consisting of formulas, patterns, devices, secret Inventions, processes, compilations of information, records and specifications (collectively "Trade Secrets"), all of which are owned by Company and used in the operation of Company's business. Additionally, Employee will have access to and may become acquainted with various files, records, customer lists, documents, drawings, specifications, equipment and similar items relating to the business of Company (collectively "Confidential Information"). All such Trade Secrets and Confidential Information, whether they are designed, conceived or prepared by Employee or come into Employee's possession or knowledge in any other way, are and shall remain the exclusive property of Company and shall not be removed from the premises of Company under any circumstances whatsoever without the prior written consent of Company. Employee promises 4

and agrees that he will not use for himself or for others, or divulge or disclose to any other person or entity, directly or indirectly, either during the term of his employment by Company or at any time thereafter, for his own benefit or for the benefit of any other person or entity or for any reason whatsoever, any of the Trade Secrets or Confidential Information described herein, which he may conceive, develop, obtain or learn about during or as a result of his employment by Company unless specifically authorized to do so in writing by Company. 5.2 Non-Interference. Employee recognizes that Company has ---------------- invested substantial effort in assembling its present employees and in developing its customer base. As a result, and particularly because of Company's many types of confidential business information, Employee understands that any solicitation of a customer or employee of Company, in an effort to get them to change business affiliations, would presumably involve a misuse of Company's confidences, Trade Secrets and Confidential Information. Employee therefore agrees that, for a period of one (1) year from the later of the date of termination of Employee's employment with Company for any reason whatsoever or the receipt by Employee of any compensation paid to Employee by Company, Employee will not influence, or attempt to influence, existing employees or customers of Company in an attempt to divert, either directly or indirectly, their services or business from Company. 6. TERMINATION OF AGREEMENT. ------------------------ 6.1 Termination by Company. Company may terminate Employee's ---------------------- employment hereunder at any time for cause without payment of severance or similar benefits. For purposes of this Section 6.1, "cause" shall mean the following events: (a) any willful breach of duty by Employee in the course of his employment, (b) the breach of any provision of this Agreement or any misrepresentation by Employee hereunder, (c) misconduct, neglect or negligence in the performance of Employee's duties and obligations, (d) disloyal, dishonest, willful misconduct, illegal, immoral or unethical conduct by Employee, (e) such carelessness or inefficiency in the performance of his duties that Employee is unfit to continue in the service of Company, (f) failure of Employee to comply with the policies or directives of Company and/or failure to take direction from Company's Board of Directors, or (g) such other conduct which is substantially detrimental to the best interests of Company. Any such termination shall become effective upon delivery of written notice to Employee. 6.2 Termination by Employee. Employee may terminate his ----------------------- employment hereunder at any time for cause. For purposes of this Section 6.2, "cause" shall mean the breach of any provision of this Agreement by Company which is not cured within thirty (30) days after Employee delivers written notice to Company 5

describing such breach. If the breach is not so cured within such thirty (30) days after delivery of such notice, the termination of employment shall become effective after the expiration of such cure period. 6.3 Death or Disability. Employee's employment with Company ------------------- shall cease upon the date of his death. In the event Employee becomes physically or mentally disabled so as to become unable for more than one hundred eighty (180) days in the aggregate in any twelve (12) month period to perform his duties on a full-time basis with reasonable accommodations, Company may, at its sole discretion, terminate this Agreement and Employee's employment. 6.4 Termination Following Automatic Renewal. In the event that --------------------------------------- this Agreement is automatically renewed pursuant to Paragraph 2 herein, either Company or Employee may terminate Employee's employment hereunder at any time and for any reason whatsoever, with or without cause, upon thirty (30) days prior written notice delivered to the other party. 6.5 Effect of Termination. Upon the termination of Employee's --------------------- employment hereunder or the expiration or termination of the Agreement, (a) Company shall pay Employee all compensation accrued and outstanding as of the date of such termination or expiration, and (b) notwithstanding anything to the contrary contained herein, the rights and obligations of each party under Paragraphs 4, 5 and 8 herein shall survive such termination or expiration. Notwithstanding anything to the contrary contained in this Agreement if, prior to the end of the three (3) year term, Employer terminates this Agreement without cause, Employee shall continue to be entitled to receive all of the compensation and other benefits provided for in Paragraph 3 for the remainder of said three (3) year term without any deduction or offset for any compensation earned or received by Employee from any other sources. 7. EMPLOYEE'S REPRESENTATIONS. As an inducement for Company to -------------------------- execute this Agreement, Employee represents and warrants to Company that the negotiation, execution and delivery of this Agreement by Employee together with the performance of his obligations hereunder does not breach or give rise to a breach under any employment, confidentiality, non-disclosure, non-competition or any other agreement, written or oral, to which Employee is a party. 8. EQUITABLE REMEDIES. ------------------ 8.1 Injunctive Relief. Employee acknowledges and agrees that the covenants set forth in Paragraphs 4 and 5 herein are reasonable and necessary for protection of Company's business interests, that irreparable injury will result to Company if 6

Employee breaches any of the terms of said covenants and that, in the event of Employee's actual or threatened breach of said covenants, Company will have no adequate remedy at law. Employee accordingly agrees that in the event of actual or threatened breach of any of such covenants, Company shall be entitled to immediate injunctive and other equitable relief, without bond and without the necessity of showing actual monetary damages. Nothing contained herein shall be construed as prohibiting Company from pursuing any other remedies available to it for such breach or threatened breach, including the recovering of any damages which it is able to prove. Each of the covenants in Paragraphs 4 and 5 shall be construed as independent of any other covenants or provisions of this Agreement. In the event of any judicial determination that any of the covenants set forth in Paragraphs 4 and 5 herein or any other provisions of the Agreement are not fully enforceable, it is the intention and desire of the parties that the court treat said covenants as having been modified to the extent deemed necessary by the court to render them reasonable and enforceable and that the court enforce them to such extent. 8.2 Specific Enforcement. Employee agrees and acknowledges that -------------------- he is obligated under this Agreement to render services of a special, unique, unusual, extraordinary and intellectual character, thereby giving this Agreement peculiar value, so that the loss thereof could not be reasonable or adequately compensated in damages in an action at law.
