Business (a) General Development of Business ThermoTrex Corporation (the Company or the Registrant) has three majority-owned subsidiaries, 79%-owned Trex Medical Corporation (Trex Medical), 67%-owned ThermoLase Corporation (ThermoLase), and 78%-owned Trex Communications Corporation (Trex Communications). Through its publicly traded Trex Medical subsidiary, the Company designs, manufactures, and markets mammography and minimally invasive digital breast-biopsy systems used for the detection of breast cancer, as well as general-purpose and specialized X-ray equipment. Through its publicly traded ThermoLase subsidiary, the Company has developed a laser-based system for the removal of unwanted hair (the SoftLight(SM) system), which is being marketed in the U.S. through ThermoLase's Spa Thira locations and through licensing agreements with physicians, and in foreign countries through joint ventures and other licensing arrangements. ThermoLase also manufactures and markets skin-care and other personal-care products. In addition, the Company performs advanced technology research in the areas of communications, avionics, X-ray detection, signal processing, and lasers. The Company's laser communications (lasercom) research is performed by its privately held Trex Communications Corporation (Trex Communications) subsidiary, which also designs and markets interactive information and voice-response systems, as well as call-automation systems. In October 1997, Trex Medical's XRE Corporation (XRE) subsidiary acquired substantially all of the assets, subject to certain liabilities, of Digitec Corporation, a manufacturer of physiological-monitoring equipment and digital-image archiving and networking systems used in cardiac catheterization procedures. Trex Medical is currently developing a full-field digital mammography system that is intended to be capable of higher image quality. The system is designed to enhance the X-ray image through software and to allow near-real-time analysis. Trex Medical expects that it will be possible to electronically transmit these images to allow off-site analysis by another radiologist, and believes this technology may also provide better images of dense breast tissue, which is often found in younger women. Trex Medical has collected clinical data and, in December 1997, submitted a 510(k) application with such data to the U.S. Food and Drug Administration (FDA), which must grant market clearance before this system can be sold commercially. Trex Medical has designed its new, high-end conventional mammography systems so that radiologists can upgrade to digital technology when it becomes available. Trex Medical believes that the digital-imaging technology being developed for this system may be adaptable to its general-purpose and specialized X-ray systems, and will seek to develop applications in these markets. Trex Medical is also working on a more advanced version of its digital technology, which incorporates a flat-panel, direct-digital detector and could provide still more information for earlier diagnoses. 2PAGE ThermoLase opened its first Spa Thira in early fiscal 1996*, and had a total of four opened by the end of fiscal 1996. In fiscal 1997, ThermoLase opened nine more domestic spas, and by October 1997 had a total of 14 domestic Spa Thira locations. In June 1996, ThermoLase initiated a program to license its SoftLight technology to physicians. As of November 1997, approximately 150 lasers were placed in practices in 33 states and certain international markets. In January 1996, ThermoLase established its first international joint venture and, during fiscal 1997, added two additional joint ventures and six additional licensing arrangements. ThermoLase's international arrangements resulted in the opening of spas in Paris in May 1997 and Lugano, Switzerland, in October 1997, and additional spas are expected to be constructed during fiscal 1998, pending regulatory approvals. ThermoLase continues to pursue an extensive research and development program to improve the efficacy and duration of its hair-removal treatment. ThermoLase has developed a modification to its procedure, called SoftLight 2.0, and began introducing this procedure in its spas and to its licensees in September 1997. Although the clinical laboratory results are encouraging, the results are preliminary and there can be no assurance that SoftLight 2.0 will be successful in improving the hair-removal process. ThermoLase believes that improvements in the hair-removal procedure are critical elements in its ability to improve the profitability of its business. In March 1997, ThermoLase filed with the FDA a 510(k) application seeking clearance to market cosmetic skin resurfacing services utilizing its SoftLight Rejuvenation(TM) Laser, including wrinkle- and skin-texture treatment. This technology, which uses the same laser as ThermoLase's hair-removal system, is designed to improve the skin's appearance and texture. During fiscal 1997, the Company created its Trex Communications subsidiary, and in September 1997 completed a private placement of 1,133,000 shares of Trex Communications common stock for net proceeds of $10.6 million. Trex Communications is developing a laser communications (lasercom) technology, which is designed to move very large amounts of data quickly via lasers without the need for wires or licensing from the Federal Communications Commission. In July 1997, Trex Communications acquired Computer Communications Specialists, Inc. (CCS), which designs and markets interactive information and voice-response systems, as well as call-automation systems. The Company continues to perform substantial amounts of government- sponsored research and development and apply its core technologies to the development of new commercial products, such as its passive microwave camera. The passive microwave camera could be used to enhance safety in * In September 1995, the Company changed its fiscal year end from the Saturday nearest December 31 to the Saturday nearest September 30. References to "fiscal 1997," "fiscal 1996," and "fiscal 1995" herein are for the years ended September 27, 1997, and September 28, 1996, and the nine months ended September 30, 1995, respectively. 3PAGE aircraft navigation during low-visibility conditions and in certain security applications. At September 27, 1997, Thermo Electron Corporation (Thermo Electron) owned 10,149,556 shares of the common stock of the Company, representing 53% of such stock then outstanding. Thermo Electron is a world leader in environmental monitoring and analysis instruments, biomedical products such as heart-assist devices, papermaking and recycling equipment, biomass electric power generation, and other specialized products and technologies. Thermo Electron also provides a range of services related to environmental quality. Thermo Electron intends for the foreseeable future to maintain at least 50% ownership of the Company. This will require the purchase by Thermo Electron of additional shares of Company common stock from time to time as the number of outstanding shares issued by the Company increases. These and any other purchases may be made either in the open market or directly from the Company. During fiscal 1997, Thermo Electron purchased 317,200 shares of the Company's common stock in the open market for a total price of $7.2 million.

Forward-looking Statements Forward-looking statements, within the meaning of Section 21E of the Securities Exchange Act of 1934, are made throughout this Annual Report on Form 10-K. For this purpose, any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words "believes," "anticipates," "plans," "expects," "seeks," "estimates," and similar expressions are intended to identify forward-looking statements. There are a number of important factors that could cause the results of the Company to differ materially from those indicated by such forward-looking statements, including those detailed under the heading "Forward-looking Statements" in the Registrant's Fiscal 1997 Annual Report to Shareholders, which statements are incorporated herein by reference. (b) Financial Information About Industry Segments The Company's business is divided into three industry segments: Medical Products manufactured by the Company's Trex Medical subsidiary, Personal-care Products and Services provided by the Company's ThermoLase subsidiary, and Advanced Technology Research, including research conducted and products distributed by its Trex Communications subsidiary. The principal products produced and services rendered by the Company in these three segments are described in detail below. (See "Principal Products and Services.") 4PAGE Financial information concerning the Company's industry segments is provided in Note 13 to Consolidated Financial Statements in the Registrant's Fiscal 1997 Annual Report to Shareholders, which information is incorporated herein by reference. (c) Description of Business (i) Principal Products and Services Medical Products Trex Medical consists of four operating units: Lorad, Bennett X-Ray Corporation (Bennett), XRE, and Continental X-Ray Corporation (Continental). Lorad manufactures and markets mammography and minimally invasive digital breast-biopsy systems. Bennett's primary product line consists of general-purpose X-ray equipment. XRE manufactures and markets X-ray imaging systems used by interventional cardiologists in the diagnosis and treatment of blockages in coronary arteries and other vessels. Continental manufactures and markets a broad line of high-end general-purpose X-ray systems, as well as specialized units. Trex Medical sells its products through a worldwide network of more than 100 independent dealers and, to a lesser extent, on a direct basis. In addition to manufacturing and marketing its own systems, the Company manufactures systems and system components as an OEM for other medical equipment companies such as United States Surgical Corporation (U.S. Surgical) and the GE Medical Systems division of General Electric Company (GE). Mammography Systems Trex Medical designs, manufactures, and markets mammography systems that are differentiated on the basis of price and performance. Its high-end models are the Lorad M-IV and the Bennett Contour Plus, both of which can be upgraded to accept the full-field digital-imaging technology being developed by Trex Medical, when available. Trex Medical also offers two lower-priced models and two mobile mammography systems. Trex Medical has collected clinical data using its prototype full-field digital mammography system and, in December 1997, submitted a 510(k) application with such data to the FDA, which must grant market clearance before the system can be marketed commercially. Trex Medical believes that demand in the market for mammography systems is driven primarily by technological innovation that results in better image quality. Although growth of the installed base has slowed, demand for new systems continues as older models are replaced with those offering technological innovations. In addition, Trex Medical believes that the market outside the United States will grow as more countries adopt mammography quality standards similar to those adopted in the United States. 5PAGE Minimally Invasive Digital Breast-biopsy Systems The Company offers a variety of minimally invasive digital breast-biopsy systems, manufactured by Lorad and Bennett, that provide an alternative to surgical biopsy. These digital breast-biopsy systems were introduced to address the disadvantages of open surgical biopsy and can be performed on an outpatient basis under local anesthetic. The typical cost of a minimally invasive breast-biopsy procedure is approximately one-third that of an open surgical biopsy. The Company offers a dedicated prone table, the StereoGuide(R), and upright, add-on systems that can be attached to most of its mammography systems. Trex Medical's StereoGuide system is the subject of a lawsuit alleging infringement of a Fischer Imaging Corporation (Fischer) patent. See "Item 3 - Legal Proceedings." Trex Medical believes that the minimally invasive digital breast-biopsy system market will grow as the procedure becomes more widely accepted by the medical community and as pressures to contain healthcare costs increase. General-purpose Radiography Trex Medical addresses the general-purpose X-ray market through its Bennett and Continental subsidiaries. Bennett primarily designs, manufactures, and markets low-cost, reliable systems to medical outpatient facilities, such as doctors' offices and surgi-care centers. Continental (and, to a lesser extent, Bennett) markets the more sophisticated and expensive X-ray systems typically used in hospitals and clinics. In addition, Bennett manufactures and markets imaging systems designed specifically for chiropractors and veterinarians. The U.S. market for general-purpose X-ray systems is stable, and consists primarily of replacement sales as customers upgrade older equipment. Trex Medical believes that the international market is substantially larger than the U.S. market and that the installed base of systems is still growing, particularly in developing countries. Trex Medical has recently expanded its international sales efforts. Trex Medical believes digital imaging will have significant application in the general-purpose and specialized X-ray markets and that the technology it develops for its full-field digital imaging system may be adaptable to these applications. In general-purpose X-ray applications, Trex Medical believes digital imaging will produce better quality images and reduce operating costs by eliminating the need for film, processing equipment, and chemicals. In addition, digital imaging will permit the electronic storage of images on magnetic or optical media, as well as the transmission of images to multiple locations. Furthermore, Trex Medical believes digital imaging could make the image intensifiers, which are large and expensive components in certain imaging systems, obsolete. 6PAGE Cardiac Catheterization, Angiography, and Electrophysiology Through its XRE subsidiary, Trex Medical designs, manufactures, and markets cardiac catheterization laboratories (also called cath labs) and positioners for cardiovascular imaging systems. XRE's imaging equipment is used in cath labs where angiography (the examination of blood vessels using X-rays following the injection of a radiopaque contrast medium) is performed by an interventional cardiologist. XRE systems are designed to provide real-time images of peripheral blood vessels and of the heart and coronary arteries for physicians performing diagnostic and interventional procedures such as balloon angioplasty. Trex Medical believes vascular and cardiovascular surgeons will increasingly use balloon angioplasty and other less-invasive techniques to treat vascular diseases. These procedures are performed under the guidance of X-ray imaging such as that provided by Trex Medical's equipment. To complement its cath labs, XRE has developed a line of digital image-processing systems, workstations, and archive alternatives. XRE's Digitec division, acquired in October 1997, manufactures physiological- monitoring equipment and digital-image archiving and networking systems used in cardiac catheterization procedures. In addition, Continental designs, manufactures, and sells electrophysiology systems that are used in the diagnosis and treatment of cardiac arrhythmia, which is characterized by the sudden, erratic beating of the heart and can result in cardiac arrest. Radiographic/Fluoroscopic Systems Through its Continental subsidiary, Trex Medical designs, manufactures, and markets radiographic/fluoroscopic (R/F) products. An R/F system is able to record dynamic events by capturing a series of images in a short period of time. For example, R/F systems are used for various gastrointestinal procedures to image in real-time the progress of a radiopaque ingested solution (typically barium) through the digestive tract. Personal-care Products and Services Laser-based Hair Removal ThermoLase's patented SoftLight system uses a low-energy, dermatology laser in combination with a specially developed lotion that directs and absorbs the laser's energy to disable hair follicles. Unlike electrolysis, the SoftLight system can disable numerous hair follicles at one time. As a result, ThermoLase believes that it will be able to address a larger market than electrolysis by offering hair removal from large areas, such as the legs. The lasers, which are similar to those used for tattoo and birthmark removal, are manufactured for ThermoLase by Trex Medical. The lotion is manufactured by ThermoLase's CBI Laboratories subsidiary. 7PAGE In a typical treatment, the area from which hair is to be removed is given a gentle cleansing. The lotion is then applied to the skin, and the area is scanned several times with the laser beam. The laser energy is absorbed by the lotion that has penetrated the hair duct, causing the temperature of the lotion to increase to a level that disables the hair follicles. The laser treatment most effectively disables hair follicles in the active growing (anagen) stage of development, and at any one time, a certain percentage of hair follicles are in the resting (telogen) stage. Therefore, it is necessary for clients to return for one or more additional treatments to ensure that each follicle is treated while in the active stage of hair growth. The number of follow-up sessions required and the time interval between treatments varies depending on the particular characteristics of the client and the anatomical site being treated. ThermoLase's spas currently offer a variety of pricing programs, including a fixed fee for a single treatment (occurring over two visits) as well as fixed fees for multiple treatments during specified time periods. The per-session cost of the SoftLight system to the customer is, in general, substantially higher than the per-session costs of alternative methods of hair removal, including waxing, electrolysis, and shaving. The total cost of the SoftLight treatments in comparison to these alternatives varies depending on factors including the body part treated, the pricing plan selected, and the length of time for which hair is removed in comparison to such alternatives. In September 1997, ThermoLase introduced SoftLight 2.0, a modification of the hair-removal process that is intended to increase the effectiveness of the treatment. ThermoLase has modified its lotion, thereby eliminating the need for waxing, part of the process used in earlier treatment protocols, and added an additional step to better direct the laser energy into the hair follicle. ThermoLase is continuing to evaluate the results of the new protocol as well as the connection between follicle damage and long-term hair removal. ThermoLase opened its first Spa Thira in early fiscal 1996, and had a total of four opened by the end of fiscal 1996. In fiscal 1997, ThermoLase opened nine more domestic spas, and by October 1997 had a total of 14 domestic Spa Thira locations. In addition, ThermoLase's international arrangements resulted in the opening of spas in Paris in May 1997 and Lugano, Switzerland, in October 1997. A spa is also under construction in Dubai in the United Arab Emirates, and additional spas are expected to be constructed in Japan, Saudi Arabia, Brazil, and London, pending regulatory approvals. The international spas are being developed pursuant to joint ventures and other licensing arrangements. In January 1996, ThermoLase established a joint venture in Japan. During fiscal 1997, ThermoLase established joint ventures in France in November 1996 and England in September 1997, and six additional licensing arrangements: in Saudi Arabia in November 1996; in Tunisia and Belgium in December 1996; in the United Arab Emirates and Oman in March 1997; in Switzerland in April 1997; in Brazil in June 1997; and in the United Kingdom (excluding England) and the Republic of Ireland in September 1997. 8PAGE In June 1996, ThermoLase initiated a program to license its SoftLight technology to physicians. In this program, ThermoLase receives a per-procedure royalty that varies depending on the anatomical site treated and pricing plan selected by the client. It also provides the physicians with the lasers and supplies that are necessary to perform the service. As of November 1997, approximately 150 lasers were placed in practices in 33 states and certain international markets. ThermoLase's existing and planned spas are designed to reflect the environment of a luxurious day spa. ThermoLase believes that the uniformity of its centers will foster brand recognition and facilitate the opening of new spas. ThermoLase currently uses medical staff, including physicians and nurses, as well as other personnel, to operate the SoftLight system at its centers. ThermoLase advertises the SoftLight system through an advertising and public relations campaign focused on exposure in fashion and health magazines as well as the national news media. Skin-care and Other Personal-care Products ThermoLase's CBI Laboratories, Inc. (CBI) subsidiary designs, develops, manufactures, and packages high-quality personal-care products for sale to retailers under its own brand names and as a contract manufacturer under arrangements with third parties. CBI develops and manufactures most of its products, which include shampoos, lotions, shower creams, bath salts, and facial treatments, using botanicals and herbal extracts. CBI has the facilities and personnel to develop new product formulations, design packaging layouts, mix and fill formulations, and package final products for distribution. CBI does not manufacture packaging such as containers and boxes, but contracts with third parties for these supplies. CBI has a portfolio of approximately 3,000 formulations, and may manufacture up to 300 different products in a quarter. Advanced Technology Research The Company is currently focusing its advanced technology research efforts in the areas of communications, avionics, X-ray detection, signal processing, and lasers. The Company has developed its expertise in these core technologies in connection with government-sponsored research and development. Laser Communication System (lasercom) Lasercom is a high-speed, high-bandwidth laser communication system, which the Company has been developing since 1989 under government-funded contracts. Through fiscal 1997, the Ballistic Missile Defense Organization has provided funding totaling $12.4 million. The lasercom system, which is in early-stage beta testing, is designed to move large amounts of data quickly via lasers, without the need for wires. Through the application of its lasercom technology, Trex Communications intends to commercialize products to meet the growing demand for high-speed, digital telecommunications technology, including opportunities in 9PAGE ground-based networks, satellite-to-satellite crosslinks, and air-based systems. In September 1996, the Company received a $4.9 million contract (with options for an additional $0.4 million) from the Defense Airborne Reconnaissance Office (DARO) for advanced development of the lasercom system for use on aircraft. Under this contract, Trex Communications will apply its lasercom technology to develop a system that could be used on unmanned reconnaissance aircraft. Lasercom would provide a horizontal communications link to quickly transmit digitized images of the ground below the aircraft, for example, to another unmanned aircraft flying near a command post hundreds of miles away, where the information could be downlinked and analyzed. Under the contract, Trex Communications is developing a fully functional prototype to be tested using small commercial jets. Passive Microwave Camera The Company is developing a passive microwave camera (PMC), which is designed to enable the user to see objects hidden by fog and clouds and to see through certain opaque objects, such as building partitions. The PMC will be a totally passive device that emits no radiation and can produce real-time video images during the day or night without the clutter typical of radar. The Company believes the largest potential application of the PMC would be the incorporation of the device into airplanes for use during takeoffs, landings, and taxiing in adverse weather conditions. PMC acceptance is subject to certification by the Federal Aviation Administration (FAA). The U.S. Army has provided approximately $10.7 million in funding for PMC development over the last five years. Development continues under a $4.0 million U.S. Army Research Laboratory contract that was awarded in fiscal 1996. Under a $700,000 grant from the National Institute of Justice, awarded in fiscal 1997, the Company plans to conduct a PMC technology demonstration and evaluation program in cooperation with local law enforcement agencies. Other Projects In addition to the full-field digital mammography system being developed by Trex Medical, the Company is developing a next-generation digital medical imaging technology. This new system would incorporate a flat-panel, direct-digital detector that could provide even more information for earlier diagnoses. This system is based on complementary metal oxide semiconductor (CMOS) technology. The CMOS system would "directly" detect the X-rays and convert them into digital information, as opposed to converting them into visible light first before being digitized, as is the case with the Company's current full-field digital technology. Trex Medical has the right to license this technology as it pertains to certain medical applications. The Company is also exploring other nonmedical applications for this flat-panel direct-digital detection technology. 10PAGE The Company is currently working on government-funded projects in several areas, including: (1) space surveillance - Under a contract from the U.S. Air Force Phillips Laboratory awarded in 1993, the Company is designing and building a system to produce high-resolution images of low- earth-orbit satellites. Through fiscal 1997, the Company has received $11.4 million under this contract. (2) ROBS (rapid optical beam steering) laser radar system - The Company has developed and extensively tested the ROBS system over the last 10 years, supported by more than $28 million in government funding. In fiscal 1996, the Company received a three-year $8.8 million contract from the U.S. Naval Air Warfare Center at China Lake, California, to continue development of this system, which is designed to simultaneously track multiple, fast-moving airborne objects with extreme precision. In July 1996, the Company received a $5.9 million contract from the U.S. Army Missile Command to build a new version of ROBS to meet Army specifications. (ii) New Products The Company's business includes the research and development of new products. (see "Principal Products and Services.") (iii) Raw Materials In connection with its SoftLight 2.0 process, ThermoLase currently uses a hydrogel product that is currently available from only one source. ThermoLase has been able to obtain an adequate supply of hydrogel to satisfy its current needs for the product, but there can be no assurance that it will be able to do so indefinitely or that it will continue to be able to obtain an adequate supply of the product at prices acceptable to ThermoLase. Other raw materials, components, and supplies purchased by the Company are either available from a number of different suppliers or from alternative sources that could be developed without a material adverse effect on the Company. To date, the Company has experienced no difficulties in obtaining these materials. (iv) Patents, Licenses, and Trademarks The Company protects its intellectual property through patents, trademarks, and trade secrets, as appropriate. In addition to relying on patents, the Company protects some of its technology as trade secrets and uses trademarks in association with certain products. The Company also enters into licensing arrangements to acquire rights in technology. The technology underlying the SoftLight system, including all patents issued thereon, belongs to the Company by virtue of a license agreement executed in February 1993 between ThermoLase and the inventor of the system, which grants ThermoLase an irrevocable, exclusive, worldwide, perpetual license to the technology in exchange for a $0.1 million commitment fee and a royalty equal to 0.25% of revenues generated from the sale or use of the SoftLight system through February 10, 2010. Patented inventions of the Company include certain mammography and other X-ray equipment, lasers, telescopes, high-power diamond switches, 11PAGE laser-radar devices, microwave cameras, a laser-based hair-removal process, a Sonic CT system, a wind-shear detector, and methods of producing composites and ultrafine particles. Patent applications are pending on certain mammography equipment, a passive microwave camera, and a free-space laser communication system. The Company is a defendant in certain patent litigation and has been notified that it allegedly infringes certain other technology owned by a third party. See information under the heading "Intellectual Property Rights, Uncertainties, and Litigation" under the heading "Forward-looking Statements" in the Registrant's Fiscal 1997 Annual Report to Shareholders, which information is incorporated herein by reference. Several of the Company's patents were the result of research programs funded by the U.S. government. With the exception of a prohibition on disclosure of classified technology, the government does not impose significant restrictions on the Company's use of government-sponsored technology. The government retains a non-exclusive, royalty-free license to use technology developed under government contracts for government purposes, and could, in certain circumstances, transfer all commercial rights to technology to a third party if the Company does not pursue its development. (v) Seasonal Influences There are no significant seasonal influences on the Company's sales of products and services. (vi) Working Capital Requirements There are no special inventory requirements or credit terms extended to customers that would have a material adverse effect on the Company's working capital. (vii) Dependency on a Single Customer Medical Products segment revenues from OEM sales of a modified design of Trex Medical's stereotactic prone breast-biopsy system to U.S. Surgical accounted for 17% of Medical Products segment revenues and 14% of the Company's total revenues in fiscal 1997. No single customer accounted for more than 10% of the revenues of the Personal-care Products and Services segment in fiscal 1997. U.S. government agencies accounted for substantially all of the Advanced Technology Research segment revenues in fiscal 1997. The Company's Advanced Technology Research segment is heavily dependent on government funding through several agencies, and the loss of any of such agencies or customers would have a material adverse effect on this segment. (viii) Backlog The backlog of firm orders for the Medical Products segment was $49.3 million as of September 27, 1997, compared with $65.3 million as of September 28, 1996. The backlog at September 28, 1996, was affected by a build-up of new orders for Trex Medical's M-IV mammography system, which 12PAGE it began shipping in late fiscal 1996, and the timing of certain orders received in late fiscal 1996. The backlog of firm orders for the Personal-care Products and Services segment, which consisted exclusively of orders for CBI's products, was $2.8 million as of September 27, 1997, compared with $5.5 million as of September 28, 1996. The Company estimates that CBI will continue to represent a decreasing portion of total segment revenues as revenues from hair-removal services increase. The backlog of firm orders for the Advanced Technology Research segment was $15.0 million as of September 27, 1997, compared with $17.9 million as of September 28, 1996. Substantially all government contract orders included in this backlog were funded at September 27, 1997. The Company does not believe that the decreases in backlog are necessarily indicative of a trend. The Company believes that substantially all of its fiscal 1997 backlog will be completed during fiscal 1998. (ix) Government Contracts Less than 10% of the Company's total revenues in fiscal 1997 were derived from contracts or subcontracts with the federal government, which are subject to renegotiation of profits or termination. There are no pending or, to the Company's knowledge, threatened renegotiations or terminations that are material to the Company. (x) Competition Medical Products The healthcare industry in general, and the market for imaging products in particular, is highly competitive. Trex Medical competes with a number of companies, many of which have substantially greater financial, marketing, and other resources than Trex Medical. Trex Medical's competitors include large companies such as GE, the Philips Medical Systems North America Company subsidiary of Philips N.V. (Philips), the Siemens Corporation subsidiary of Siemens AG (Siemens), Toshiba American Medical Systems, Inc., Toshiba America MRI, Inc., Shimadzu, and Picker International, Inc., which compete in most diagnostic imaging modalities, including X-ray imaging. In addition, a significant portion of Trex Medical's sales are to U.S. Surgical and GE through OEM arrangements. The products sold through such OEM agreements compete with those offered by Trex Medical directly and through its independent dealers. Trex Medical's StereoLoc II, Cytoguide, and StereoGuide breast-biopsy systems compete with products offered by GE, Fischer Imaging Corporation, and Philips, and with conventional surgical biopsy procedures. Trex Medical competes primarily on the basis of product features, product performance, and reputation as well as price and service. Trex Medical believes that competition is likely to increase as a result of healthcare cost-containment pressures and the development of alternative diagnostic and interventional technologies. Personal-care Products and Services ThermoLase expects that, in the near term, the principal competitors relative to the hair-removal treatment using the SoftLight system will be electrolysis providers. The electrolysis market is characterized by many 13PAGE small practitioners. Although ThermoLase believes that it has a significant competitive advantage over electrolysis, it does not have the well-established network of client relationships that many electrologists have. Over time, it is expected that ThermoLase will face growing competition from other laser-based hair-removal services. Four other laser manufacturers received market clearance from the FDA in 1997 for hair removal. ThermoLase expects that others, in addition to the laser companies that currently have clearance for hair removal, will seek to develop similar technologies and products that may compete directly with the SoftLight system. ThermoLase's services will also compete with other hair-removal products and methods. ThermoLase believes that competition for its hair-removal services is based primarily on efficacy, price, comfort, and safety. Should it receive clearance to market the SoftLight Rejuvenation Laser system for skin resurfacing, ThermoLase expects that its principal competitors will be providers of carbon dioxide laser and chemical peel resurfacing and traditional spa-based services. ThermoLase believes that its SoftLight Rejuvenation skin treatment system will offer customers an alternative to more aggressive skin-texture and wrinkle-treatment methods. The professional skin-care and bath-and-body products markets are highly competitive. In selling its Salon product line, CBI competes with a number of small manufacturers and divisions of larger companies. The competition in this market is fragmented with no one competitor dominating the market. In the Custom Design and Store Brands groups, CBI competes with numerous contract packaging companies that can prepare and package custom formulations for customers. Some of these competitors have substantially greater financial, marketing, and research and development resources than those of ThermoLase. CBI competes in these markets by offering its customers exclusive product lines that ThermoLase believes can generally be sold at a lower price but with higher margins than CBI's competitors. Advanced Technology Research Trex Communications is engaged in segments of the telecommunications industry that are extremely competitive. In its lasercom division, Trex Communications expects to compete with large telecommunication service providers, such as the regional Bell operating companies, competitive access providers, and microwave and cellular service providers. Such companies have substantially greater financial, technical, marketing, and other resources than Trex Communications. Trex Communications' goal, however, is to enter into strategic relationships with certain of these competitors to provide components for the network systems that Trex Communications is developing and to market and sell lasercom technology and services. No assurance can be given that Trex Communications will be successful in creating such strategic relationships. In addition, Trex Communications' lasercom division expects to compete with other laser- based communication hardware and software providers, most of which have greater financial, technical, marketing, and other resources than Trex Communications. 14PAGE Trex Communications' CCS subsidiary competes with a number of call automation companies, primarily on the basis of product features, product performance, and reputation, as well as price and service. Some of CCS' competitors have substantially greater financial, technical, marketing, and other resources than CCS. The Company competes for its research and development programs principally on the basis of technological innovations. As government funding becomes more scarce, particularly for defense projects, the competition for such funding will become more intense. In addition, as the Company's programs move from the development stage to procurement of large-scale, electro-optical systems, competition is expected to develop and intensify. Some of the Company's competitors for research and development funding and procurement have substantially greater resources than those of the Company. As the Company develops commercial products, it expects to encounter competition from various sources, including companies that will have substantially greater technical, marketing, and financial resources than those of the Company. The Company believes that its overall success will depend primarily on its ability to continue to make technological advances. (xi) Research and Development During the years ended September 27, 1997, and September 28, 1996, and the nine months ended September 30, 1995, the Company incurred $32,067,000, $24,986,000, and $13,430,000, respectively, on internally sponsored research and development programs, and $11,667,000, $10,278,000, and $11,803,000, respectively, on research and development programs sponsored by others. Approximately 344 professional employees were engaged full-time in research and development activities at September 27, 1997. (xii) Environmental Protection Regulations The Company believes that compliance with federal, state, and local environmental regulations will not have a material adverse effect on its capital expenditures, earnings, or competitive position. (xiii) Number of Employees As of September 27, 1997, the Company had a total of 1,712 employees. (d) Financial Information about Exports by Domestic Operations Financial information about exports by domestic operations is summarized in Note 13 to Consolidated Financial Statements in the Registrant's Fiscal 1997 Annual Report to Shareholders, which information is incorporated herein by reference. 15PAGE (e) Executive Officers of the Registrant Present Title (Fiscal Year First Name Age Became Executive Officer) --------------------------------------------------------------------- Gary S.

The Company also leases 25,000 square feet of office and warehouse facilities in San Diego under leases expiring in fiscal 1998. The Company believes that its facilities are in good condition and are suitable and adequate to meet current needs. Item 3. Legal Proceedings In April 1992, Fischer Imaging Corporation (Fischer) commenced a lawsuit in the United States District Court, District of Colorado, against Lorad, alleging that Lorad's prone breast-biopsy system infringes a Fischer patent on a precision mammographic needle-biopsy system. As of September 27, 1997, the Company had recognized aggregate revenues of approximately $107.1 million from the sale of such systems. The suit requests a permanent injunction, treble damages, and attorneys' fees and expenses. If the Company is unsuccessful in defending this lawsuit, it may be enjoined from manufacturing and selling its prone breast-biopsy system without a license from Fischer. No assurance can be given that the Company will be able to obtain such a license, if required, on commercially reasonable terms, if at all. In addition, the Company may be subject to damages for past infringement. No assurance can be given as to the amount that the Company may eventually be required to pay in expenses or in such damages.
