                                     PART I

    Item 1. Business

    (a)  General Development of Business

         ThermoTrex Corporation (the Company or the Registrant) has two
    publicly traded subsidiaries, 64%-owned ThermoLase Corporation
    (ThermoLase) and 80%-owned Trex Medical Corporation (Trex Medical).
    Through its 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 salons and through licensing agreements with physicians, and in
    foreign countries through joint ventures and other licensing arrangements
    with companies or individuals that are experienced in those locations. In
    addition, ThermoLase's wholly owned CBI Laboratories, Inc. (CBI)
    subsidiary manufactures and markets skin-care and other personal-care
    products. Through its Trex Medical subsidiary, the Company designs,
    manufactures, and markets mammography and minimally invasive stereotactic
    breast-biopsy systems used for the detection of breast cancer, as well as
    general-purpose and specialty X-ray equipment. The Company also conducts
    advanced technology research in communications, avionics, X-ray
    detection, signal processing, advanced-materials technology, and lasers.

         In April 1995, ThermoLase received clearance from the U.S. Food and
    Drug Administration (FDA) to market services using the SoftLight system,
    and began earning revenue from the SoftLight system in the first quarter
    of fiscal 1996* as a result of opening its first commercial salon (Spa
    Thira) in La Jolla, California, in November 1995. ThermoLase opened
    additional salons in Dallas in June 1996, in Houston and Beverly Hills in
    September 1996, in Denver in October 1996, and in Boca Raton in November
    1996. ThermoLase also plans to open a spa in suburban Detroit in December
    1996 and has signed leases for four additional sites in Greenwich,
    Connecticut; Manhasset, New York; suburban Minneapolis; and Palm Beach,
    Florida. Lease negotiations are under way for additional sites.

         In January 1996, ThermoLase entered into a joint venture to market
    the SoftLight process in Japan, as well as its laser-based skin-
    rejuvenation process, if and when available. Before opening the first spa
    in Japan, the joint venture must obtain Japanese regulatory clearance to
    market the SoftLight process, for which it is presently conducting
    clinical studies to obtain data to submit to the appropriate Japanese
    regulatory authorities. ThermoLase currently holds a 50% stake in the
    joint venture, with an option to increase its ownership to 51% pursuant
    to a fair-value purchase option.

         In June 1996, ThermoLase initiated a program to license its
    SoftLight technology to doctors. In this program, ThermoLase licenses its
    technology to doctors and receives a per-procedure royalty that varies
    depending on the location treated.  ThermoLase also provides the doctors
    with the lasers and supplies that are necessary to perform the service. A
    total of 55 doctors were licensees as of December 1, 1996.



    * 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 1996," "fiscal 1995," and "1994" herein are for
      the year ended September 28, 1996, the nine months ended September 30,
      1995, and the year ended December 31, 1994, respectively.
                                        2PAGE
<PAGE>
         In June 1996, ThermoLase purchased $4.4 million of convertible
    preferred stock of AntiCancer Incorporated (AntiCancer), representing an
    approximate 10% equity interest on a fully diluted basis. San Diego-based
    AntiCancer is developing technology that may have the potential to
    enhance the effectiveness of the SoftLight process. In this technology,
    liposomes, which have been proven to be effective delivery agents in
    other applications, might provide a more efficient method of delivering
    carbon, which is the primary ingredient in the lotion used in the
    SoftLight process, to hair follicles. ThermoLase has signed an agreement
    to license this technology as it pertains not only to hair removal, but
    also to stimulation of hair growth, suppression of hair growth, and hair
    coloring.

         In November 1996, ThermoLase entered into a joint venture to market
    its SoftLight process in France, as well as its laser-based skin-
    rejuvenation process, if and when available. ThermoLase's partner in the
    joint venture is an affiliate of Groupe Jacques Dessange, which is a
    leading provider of premium hair- and skin-care services in France. The
    joint venture plans to open Spa Thira salons in France and to sublicense
    to French physicians and others the right to perform services using the
    SoftLight system.

         In November 1996, ThermoLase entered into a license agreement to
    allow a third party to market the SoftLight process in Saudi Arabia, as
    well as its laser-based skin-rejuvenation process, if and when available.

         ThermoLase is investigating other applications for its laser-based
    technology, and in June 1995 was granted a patent covering a laser-based
    skin-rejuvenation system, which ThermoLase believes may be used to remove
    the outer layers of dead skin cells. Carbon dioxide (CO2) lasers have
    recently been used to remove wrinkles, but their use has been associated
    with long healing times and, in some cases, undesirable side effects.
    ThermoLase believes that the skin-rejuvenation process that it is
    developing will cause less skin damage than existing laser skin
    treatments that use a CO2 laser. Although the safety of using lasers for
    skin treatments has been established by several systems that are already
    approved by the FDA for the removal of birthmarks and tattoos, ThermoLase
    may not commercially sell its skin-rejuvenation system, or services using
    the system, until it has received clearance from the FDA. ThermoLase is
    currently conducting clinical trials and plans to submit a 510(k)
    application containing clinical data by the end of the second quarter of
    fiscal 1997.

         In July 1996, the Company completed the public spinout of its Trex
    Medical subsidiary. Trex Medical issued 2,875,000 shares of its common
    stock in an initial public offering, and 871,832 shares of its common
    stock in a concurrent rights offering, for net proceeds of $49.1 million.

         Trex Medical, which was incorporated in September 1995, consists of
    four operating units: Lorad, Bennett X-Ray Corporation (Bennett), XRE
    Corporation (XRE), and Continental X-Ray Corporation (Continental). In
    September 1995, ThermoTrex acquired and subsequently transferred to Trex
    Medical all of the outstanding capital stock of Bennett; in May 1996,
    Trex Medical acquired substantially all of the assets and liabilities of
                                        3PAGE
<PAGE>
    XRE for approximately $18.5 million in cash, net of cash acquired and
    including the repayment of debt; and in September 1996, Trex Medical
    acquired substantially all of the assets and liabilities of Continental
    for approximately $18.4 million in cash, net of cash acquired and
    including the repayment of debt.

         Each of Trex Medical's operating units specializes in manufacturing
    a particular type of imaging equipment for different market segments.
    Lorad, acquired by the Company in 1992 and transferred to Trex Medical in
    September 1995, manufactures and markets mammography and minimally
    invasive stereotactic breast-biopsy systems, which provide a
    cost-effective, less-invasive alternative to open surgery for the biopsy
    of suspicious breast lesions. Bennett's product line consists primarily
    of general-purpose X-ray equipment, but also includes mammography
    systems, a stereotactic breast-biopsy system, and X-ray units used by
    chiropractors and veterinarians. 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. XRE also
    manufactures electrophysiology products that aid doctors in diagnosing
    and treating cardiac arrhythmia. Continental manufactures and markets a
    broad line of general-purpose and specialty X-ray systems, including
    radiographic fluoroscopy (R/F) systems used to diagnose gastrointestinal
    disorders. Continental also manufactures electrophysiology products and
    mammography systems.

         Trex Medical is currently developing a full-breast digital
    mammography system that is intended to yield higher image quality, permit
    the enhancement of an X-ray image through software, and allow off-site
    analysis of the X-ray image. Trex Medical believes this technology may
    also provide better images of dense breast tissue, which is often found
    in younger women. Trex Medical is currently collecting clinical data to
    be submitted with its 510(k) application to the 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 this 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 and specialized radiography systems, and will seek to develop
    applications in these markets. Trex Medical is also working on a more
    advanced version of its existing digital technology, which incorporates a
    flat-panel, direct-digital detector and could provide even more
    information for earlier diagnoses.

         The Company continues to focus on applying its core technologies to
    the development of new commercial products, including a passive microwave
    camera and a laser communication system called lasercom. The passive
    microwave camera could be used to enhance safety in aircraft navigation
    during low-visibility conditions and in certain security applications.
    The lasercom system could one day be used as a satellite-to-satellite
    communication system to transmit phone calls, faxes, and video
    teleconferences across the globe. The Company continues to perform
    substantial amounts of government-sponsored research and development.

         At September 28, 1996, Thermo Electron Corporation (Thermo
    Electron) owned 9,711,282 shares of the common stock of the Company,

                                        4PAGE
<PAGE>
    representing 51% of such stock then outstanding. Thermo Electron is a
    world leader in environmental monitoring and analysis instruments,
    biomedical products such as heart-assist devices and mammography systems,
    papermaking and paper-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 on the open market or
    directly from the Company. During fiscal 1996, Thermo Electron purchased
    50,000 shares of the Company's common stock in the open market for a
    total price of $1.8 million. See Note 6 to Consolidated Financial
    Statements in the Registrant's Fiscal 1996 Annual Report to Shareholders
    for a description of outstanding stock options.

    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. These statements involve a number of risks and
    uncertainties, including those detailed under the caption "Forward-
    looking Statements" in the Registrant's Fiscal 1996 Annual Report to
    Shareholders 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. The principal products
    produced and services rendered by the Company in these three segments are
    described in detail below. (See "Principal Products and Services.")

         Financial information concerning the Company's industry segments is
    provided in Note 13 to Consolidated Financial Statements in the
    Registrant's Fiscal 1996 Annual Report to Shareholders and is
    incorporated herein by reference.

    (c)  Description of Business

         (i) Principal Products and Services

    Medical Products

         Through its Trex Medical subsidiary, the Company designs,
    manufactures, and markets mammography and minimally invasive stereotactic
    breast-biopsy systems used for the detection of breast cancer, as well as
    general-purpose and specialty X-ray equipment and radiographic
    fluoroscopy systems. Trex Medical sells its products through a worldwide
    network of more than 100 independent dealers and, to a lesser extent, on
                                        5PAGE
<PAGE>
    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), the GE Medical Systems division of General
    Electric Company, Inc. (GE), the Philips Medical Systems North America
    Company subsidiary of Philips N.V. (Philips), and the Picker
    International, Inc. subsidiary of GEC, Inc. (Picker International).

    Mammography and Breast-biopsy Systems

         Trex Medical is the world's leading manufacturer of mammography
    equipment and minimally invasive breast-biopsy systems. Trex Medical's
    systems are differentiated on the basis of price and performance, with
    high-end models including the recently introduced Lorad M-IV and the
    Bennett Contour, which offers a patented tilt C-arm that permits the
    system to tilt toward, or away from, the patient to allow for imaging of
    a greater area of the breast. The M-IV incorporates the optional
    High-Transmission Cellular (HTC)(TM) grid, which reduces X-ray scattering
    while blocking fewer primary X-rays, resulting in higher-contrast images
    with lower radiation doses. The Company's lower-priced models include the
    Lorad M-III and the Bennett MF-150, which do not offer all of the
    features of the high-end models and are marketed to more cost-conscious
    consumers. In addition, the Company offers two mobile mammography
    systems.

         The Company currently has a prototype full-breast digital imaging
    mammography system and expects to submit data using this prototype to the
    FDA for clearance, which is required before the Company can commercially
    market it. The Company is currently developing a next-generation
    full-breast digital mammography system, which would replace the film with
    a solid-state detector capable of directly recording the X-ray image in
    an electronic format. The system is designed to substantially increase
    image contrast without a significant decrease in image resolution.

         Trex Medical also offers a variety of minimally invasive
    stereotactic breast-biopsy systems, designed to provide an alternative to
    surgical breast biopsies. Compared with open surgery, a stereotactic
    breast-biopsy procedure generally removes only a small tissue sample,
    resulting in minimal scarring, which can affect the accuracy of future
    mammograms, and is generally performed under local anesthetic on an
    outpatient basis, resulting in significantly lower cost. Recent studies
    indicate that stereotactic needle biopsy is equally effective compared
    with surgical biopsy in determining whether a suspicious lesion is
    malignant, and the typical cost of a stereotactic needle-biopsy procedure
    is approximately one third of the cost of a surgical biopsy. The Company
    offers a dedicated, prone table called 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 offers a digital spot imaging option with all of its
    stereotactic breast-biopsy systems. Although not capable of imaging the
    entire breast, digital spot imagers are capable of capturing an area
    large enough to cover a suspicious lesion. The Company's digital spot
                                        6PAGE
<PAGE>
    imaging systems can record and display an X-ray image in approximately 10
    seconds. Since the image is recorded in electronic format, a computer can
    quickly plot the location of the lesion and aim the needle gun once the
    lesion has been located with a cursor on the computer screen. A
    stereotactic breast-biopsy procedure using digital spot imaging can be
    performed in as short a time as 10 minutes, compared with a typical time
    of 45 minutes using a film-based system.

         The Company believes that demand in the market for mammography
    systems is driven primarily by technological innovation that result 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 recently adopted in
    the United States. Trex Medical believes that the stereotactic
    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 Radiography

         Trex Medical addresses the general radiography (X-ray) market
    through its Bennett and Continental subsidiaries. Bennett designs,
    manufactures, and markets office-based X-ray systems, which are basic
    systems generally used in medical outpatient facilities, such as doctors'
    offices and surgi-care centers. Bennett has focused on this segment of
    the market by providing low-cost, reliable systems. Bennett and
    Continental also design, manufacture, and market more sophisticated and
    expensive radiographic 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 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 offers two linear tomography systems: the Bennett
    BT-300 and the Continental Precision Movement Tomography (PMT)
    radiographic/tomographic system. In a linear tomography procedure, the
    X-ray tube sweeps over the patient in one direction with the film tray
    sweeping under the patient in the opposite direction. The resulting image
    provides an unobstructed view at a desired plane within the patient's
    body, of the kidneys, for example. The Company believes that for a number
    of applications its tomography systems may be a cost-effective
    alternative to computed tomography (CT) scanners.

         The Company believes digital imaging will have significant
    application in the general and specialized radiographic markets and that
    the technology it develops for its full-breast digital imaging system may
    be adaptable to these applications. In general X-ray applications, the
    Company believes digital imaging will produce better quality images and
                                        7PAGE
<PAGE>
    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, the Company
    believes digital imaging could make the image intensifiers, which are
    large and expensive components in certain imaging systems, obsolete.

    Cardiac Catheterization, Angiography, and Electrophysiology

         Through its XRE subsidiary, acquired in May 1996, Trex Medical
    designs, manufactures, and markets complete cardiac catheterization
    laboratories (also called cath labs) and positioners for cardiovascular
    imaging systems. XRE's imaging equipment is used in cath labs where
    angiography (examination of the blood vessels using X-rays following the
    injection of a radio-opaque contrast medium) is performed by an
    interventional cardiologist. The entire system is designed to provide
    real-time images of the heart and coronary arteries for physicians
    performing interventional procedures, such as a diagnostic angiogram or
    balloon angioplasty, which has become a common alternative to open-heart
    bypass surgery.

         Both XRE and Continental design, manufacture, and sell
    electrophysiology systems 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 Fluoroscopy Systems

         Through its Continental subsidiary, acquired in September 1996,
    Trex Medical designs, manufactures and markets 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 the progress of a radio-opaque
    ingested solution (typically barium) through the digestive tract.
    Continental produces R/F systems that use advanced high-frequency
    generators that provide pulsed power, resulting in substantially reduced
    radiation exposure to the patient. Continental's R/F products include the
    new DigiSpot 2000, a high-speed digital imaging system that records the
    image in an electronic format, permitting the electronic storage of
    images on magnetic or optical media and the transmission of images to
    multiple locations with image quality comparable with film-based systems.

    Personal-care Products and Services

    Laser-based Hair Removal

         ThermoLase's patented SoftLight system uses a low-energy,
    dermatology laser in combination with a lotion that 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 
                                        8PAGE
<PAGE>
    removal, are manufactured for ThermoLase by Trex Medical. The lotion is
    manufactured by ThermoLase's CBI Laboratories subsidiary.

         In a typical treatment, the area from which hair is to be removed
    is first waxed to open each hair duct. The lotion is then applied, and
    the area is scanned with the laser beam. The laser energy passes through
    the skin and 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. Each client typically has a series of
    treatments, for which each Spa Thira currently offers several pricing
    programs, including fixed fees for one or more treatments and fixed fees
    for treatments during specified time periods. ThermoLase continues to
    invest in research and development to improve the efficacy of the system
    and increase the length of time between treatments.

         In April 1995, ThermoLase received clearance from the FDA to market
    services using the SoftLight system, and began earning revenue from the
    SoftLight system in the first quarter of fiscal 1996 as a result of
    opening its first commercial salon (Spa Thira) in La Jolla, California,
    in November 1995. ThermoLase opened additional salons in Dallas in June
    1996, in Houston and Beverly Hills in September 1996, in Denver in
    October 1996, and in Boca Raton in November 1996. ThermoLase also plans
    to open a spa in suburban Detroit in December 1996, and has signed leases
    for four additional sites in Greenwich, Connecticut; Manhasset, New York;
    suburban Minneapolis; and Palm Beach, Florida. Lease negotiations are
    under way for additional sites.

         In June 1996, ThermoLase initiated a program to license its
    SoftLight technology to doctors. In this program, ThermoLase licenses its
    technology to doctors and receives a per-procedure royalty that varies
    depending on the location treated. ThermoLase also provides the doctors
    with the lasers and supplies that are necessary to perform the service. A
    total of 55 doctors were licensees as of December 1, 1996.

         In January 1996, ThermoLase entered into a joint venture to market
    the SoftLight process in Japan, as well as its laser-based skin-
    rejuvenation process, if and when available. Before opening the first spa
    in Japan, the joint venture must obtain Japanese regulatory clearance to
    market the SoftLight process, for which it is presently conducting
    clinical studies to obtain data to submit to the appropriate Japanese
    regulatory authorities. ThermoLase currently holds a 50% stake in the
    joint venture, with an option to increase its ownership to 51% pursuant
    to a fair-value purchase option. During fiscal 1996, ThermoLase received
    $2.0 million in minimum guaranteed payments in accordance with
    contractual terms. ThermoLase will receive $1.0 million in minimum
    guaranteed payments in fiscal 1997, subject to certain exceptions in the
    event the joint venture is unable to obtain patent protection in Japan on
    prescribed terms.

         In November 1996, ThermoLase entered into a joint venture to market
    its SoftLight process in France, as well as its laser-based skin-
    rejuvenation process, if and when available. The joint venture plans to
    open Spa Thira salons in France and to sublicense to French physicians
    and others the right to perform services using the SoftLight system.
    ThermoLase has committed to provide up to $5.0 million to fund working 
                                        9PAGE
<PAGE>
    capital requirements of the joint venture in exchange for its 50% stake
    in the joint venture. ThermoLase's partner in the venture has also
    committed to fund up to $5.0 million in exchange for its 50% ownership.
    ThermoLase has licensed the technology to perform the SoftLight process
    to the joint venture, and will receive a royalty based on the joint
    venture's revenues.

         In November 1996, ThermoLase entered into a license agreement with
    a third party, which will market the SoftLight process through Spa Thira
    salons and sublicensing arrangements in Saudi Arabia, as well as its
    laser-based skin-rejuvenation process, if and when available. Pursuant to
    the agreement, ThermoLase will receive up-front fees totaling $1.0
    million over a two-year period and a fee based on revenues derived from
    SoftLight services.

         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 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

         In December 1993, ThermoLase acquired CBI, a designer, developer,
    manufacturer, and packager of 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 using botanicals and herbal extracts,
    with no animal fats, chemical dyes, or artificial aromas. 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.

         CBI divides its business into three primary groups: Salon, Custom
    Design, and Store Brands. The Salon group, which represents CBI's
    original business, develops and manufactures a line of products primarily
    sold directly by CBI to professional estheticians in skin-care salons and
    spas. The Custom Design group markets CBI's manufacturing and design
    services primarily to major retailers and multilevel marketing groups for
    custom design of private-label product lines. The Store Brands group
    markets complete proprietary product lines created by CBI, including
    product formulations, packaging, brand name, and promotional materials,
    which can be purchased by a customer for sale in its retail outlets as an
    exclusive product line.

         CBI's marketing and sales strategy varies by product line, but
    generally includes phone solicitations and local representatives. In
    addition, ThermoLase expects its network of Spa Thira salons and
    physicians' offices where SoftLight services are offered to provide a
    retail outlet for CBI's salon products. To support its marketing
    activities, CBI attends industry trade shows and advertises in major
    trade publications.

    Advanced Technology Research

          The Company is currently focusing its advanced technology research
    efforts in the areas of communications, avionics, X-ray detection, signal
    processing, materials technology, and lasers. The Company has developed
    its expertise in these core technologies in connection with
    government-sponsored research and development.

    Passive Microwave Camera

         The Company is developing a passive microwave camera (PMC) to see
    objects hidden by fog and clouds and to see through certain opaque
    objects, such as building partitions. The Company's PMC could thus
    improve safety in aircraft navigation and provide enhanced surveillance
    capabilities.

         The Company's PMC is intended to combine the capabilities and
    advantages of infrared imaging and radar detection to form thermal images
    at microwave frequencies. Like infrared imaging, but unlike radar, 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. Like radar, but unlike infrared imaging, the
    PMC will have the ability to see through fog, smoke, clouds, and some
    opaque objects. For example, microwave imaging devices have penetrated
    cloud cover to produce identifiable images of highways from helicopters.
    The Company's goal is that its PMC will achieve resolution of objects
    that are several feet, to several tens of feet, in size at a distance of
    one mile and that resolution will increase as distances decrease.

         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. The
    Company's PMC is subject to approval by the Federal Aviation
    Administration (FAA). The U.S. Army has provided approximately $6.0
    million in funding for PMC development over the last four years. In
    fiscal 1996, the U.S. Army Research Laboratory awarded ThermoTrex an
    additional $4.0 million contract to continue development. Under the
    previous funding, ThermoTrex built and field-tested a first-generation
    camera. The additional funding will be used to conduct further upgrades
    that are intended to improve performance and make the camera more user
    friendly. In addition, ThermoTrex is developing a flightworthy
    second-generation camera for in-flight testing. Because the Army is
    interested in the potential for using this system on unmanned aircraft,
    the Company plans to develop a new system architecture that is compatible
    with an unmanned vehicle, with the goal of producing very-high-resolution
    images from long distances.

         Under a two-year $1.7 million cooperative agreement announced in
    early 1995, the Company is developing a more compact version of the PMC
    for the National Aeronautics and Space Administration. Under the terms of
    this agreement, the Company will provide matching funds of $1.3 million
    and its subcontractor, Aerojet GenCorp., will contribute $0.8 million.
                                       11PAGE

    Laser Communication System (lasercom)

         The Company is developing a laser communication system called
    lasercom that could help ease the burden that data transmission is
    placing on existing communication systems. The commercial lasercom system
    envisioned by ThermoTrex would employ a constellation of low-earth-orbit
    satellites. The information being transmitted would be uplinked via radio
    waves to the closest satellite, then relayed via laser beams to
    intermediate satellites before being downlinked via radio waves near the
    recipient.

         Since 1989, the Company has developed lasercom under the
    sponsorship of The Ballistic Missile Defense Organization, which has
    provided funding totaling approximately $11.8 million through the end of
    fiscal 1996. The military would benefit from the speed and security that
    lasercom could provide. In September 1995, the Company successfully
    demonstrated the data transmission capability of the system when data
    were broadcast over a distance of almost 100 miles.

         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, the Company 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, the Company is developing a
    fully functional prototype to be tested using small commercial jets.

    Other Projects

         The Company is developing a more advanced version of its existing
    digital medical imaging technology, which Trex Medical currently
    incorporates into certain of its mammography systems. This
    next-generation 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-breast 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 technology.

         The Company is currently working on government projects in several
    areas, including: (1) space surveillance -- Under an $8.0 million
    contract from the U.S. Air Force Phillips Laboratory that was awarded in
    1993, the Company is designing and building a system to produce
    high-resolution images of low-earth-orbit satellites. (2) ROBS (rapid
    optical beam steering) laser radar system -- ThermoTrex has developed and
    extensively tested the ROBS system over the last nine years, supported by
    more than $23 million in government funding. In fiscal 1996, the Company
                                       12PAGE
<PAGE>
    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.

         One of the Company's long-term research and development programs is
    the development of a Sonic CT(TM) (Computed Tomography) system that uses
    acoustic waves to form high-resolution images of breast tissue. The
    Company has deferred spending additional resources on Sonic CT at the
    present time, so that it may concentrate its resources more directly on
    its digital imaging research and development.

         (ii) New Products

         The Company's business includes the research and development of new
    products. (see "Principal Products and Services.")

         (iii) Raw Materials

         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,
    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 technologies
    owned by third parties. See information under the heading "Intellectual
                                       13PAGE

    Property Rights, Uncertainties and Litigation" under the caption
    "Forward-looking Statements" in the Registrant's Fiscal 1996 Annual
    Report to Shareholders 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

         No single customer accounted for 10% or more of the Company's total
    revenues in fiscal 1996. 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 11% of Medical Products segment
    revenues in fiscal 1996. No single customer accounted for more than 10%
    of the revenues of the Personal-care Products and Services segment.
    Advanced Technology Research segment revenues from U.S. government
    agencies accounted for 85% of that segment's revenues in fiscal 1996. 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
    $65.3 million as of September 28, 1996, compared with $45.4 million as of
    September 30, 1995. The backlog of firm orders for the Personal-care
    Products and Services segment was $5.5 million as of September 28, 1996,
    compared with $4.6 million as of September 30, 1995. The backlog of firm
    orders for the Advanced Technology Research segment was $17.9 million as
    of September 28, 1996, compared with $10.6 million as of September 30,
    1995. This backlog includes government contract orders that are firm but
    not yet funded of $1.6 million at September 30, 1995. The Company
    believes that substantially all of its fiscal 1996 backlog will be
    completed during fiscal 1997.
                                       14PAGE
<PAGE>
         (ix) Government Contracts

         Less than 10% of the Company's total revenues in fiscal 1996 were
    derived from contracts or subcontracts with the federal government, which
    are subject to renegotiation of profits or termination. The Company does
    not have any knowledge of threatened or pending renegotiations or
    terminations.

         (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, Philips, the
    Siemens Corporation subsidiary of Siemens AG (Siemens), Toshiba American
    Medical Systems, Inc. and Toshiba America MRI, Inc. (collectively,
    Toshiba), Shimadzu and Picker International, 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, GE, and
    Philips through OEM arrangements. The products sold through such OEM
    agreements compete with those offered by Trex Medical and its independent
    dealers. Trex Medical competes in these markets 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 treatment using the SoftLight system will be
    electrolysis providers. The electrolysis market is characterized by many
    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. In addition, a number of laser manufacturers have announced that
    they have filed applications with the FDA seeking to obtain clearance to
    market a laser for hair removal. Although, to date, none of these
    companies has been successful in obtaining such a clearance, a number of
    them are currently marketing substantially similar devices for
    indications other than hair removal. The Company believes that certain of
    these devices are being used "off-label" for hair removal by some
    physicians in the U.S. and are being marketed for hair removal in some
    foreign jurisdictions where regulatory clearance is not as stringent as
    it is in the United States. ThermoLase's products and services will also
    compete with other hair-removal products. If ThermoLase's technology is
    accepted by the general public, it expects that others will seek to
    develop similar technologies and products that may compete directly with
    the SoftLight system.
                                       15PAGE
<PAGE>
         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 the Company. CBI competes in these markets by
    offering its customers an exclusive product line that the Company
    believes can generally be sold at a lower price but with higher margins
    than CBI's competitors.

    Advanced Technology Research

         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 year ended September 28, 1996, the nine months ended
    September 30, 1995, and the year ended December 31, 1994, the Company
    incurred approximately $24,986,000, $13,430,000, and $14,172,000,
    respectively, on internally sponsored research and development programs,
    and $10,278,000, $11,803,000, and $14,452,000, respectively, on research
    and development programs sponsored by others. Approximately 268
    professional employees were engaged full-time in research and development
    activities at September 28, 1996.

         (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 28, 1996, the Company had a total of 1,383
    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

    Item 2. Properties

         The location and general character of the Company's principal
    properties as of September 28, 1996, are as follows:

         Trex Medical owns two office and manufacturing facilities: a 63,500
    square-foot facility in Danbury, Connecticut, and a 163,000 square-foot

    square-foot office and manufacturing facility in Copiague, New York,
    under a lease expiring in 2005, and a 156,000 square-foot office and
    manufacturing facility in Littleton, Massachusetts, under a lease
    expiring in 2012. Trex Medical has entered into a lease for a new 60,000
    square-foot building to be constructed adjacent to its existing facility
    in Danbury, Connecticut. The lease will commence upon completion of the
    building, which is expected to occur in December 1996, and has a term of
    10 years.

    Personal-care Products and Services

         ThermoLase occupies approximately 213,000 square feet of office and
    manufacturing space in Carrollton, Texas, under a lease expiring in 2004,
    through its CBI subsidiary. ThermoLase also occupies approximately 43,000
    square feet of retail space in California, Texas, Colorado, and Florida
    for its Spa Thira salons, under leases expiring from 2000 through 2006. 

    Advanced Technology Research

         The Company currently leases 90,000 square feet of office,
    engineering, and laboratory space in San Diego under a lease expiring in
    2006. The Company also leases a 10,000 square-foot office and warehouse
    facility in San Diego as a tenant-at-will. 

         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 28, 1996, the Company had aggregate revenues of approximately
    $63.1 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 StereoGuide 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.

    To the Shareholders and Board of Directors of ThermoTrex Corporation:

         We have audited, in accordance with generally accepted auditing
    standards, the consolidated financial statements included in ThermoTrex
    Corporation's Annual Report to Shareholders incorporated by reference in
    this Form 10-K, and have issued our report thereon dated November 1,
    1996. Our audits were made for the purpose of forming an opinion on those
    statements taken as a whole. The schedule listed in Item 14 on page 21 is
    the responsibility of the company's management and is presented for
    purposes of complying with the Securities and Exchange Commission's rules
    and is not part of the basic consolidated financial statements. The
    schedule has been subjected to the auditing procedures applied in the
    audits of the basic consolidated financial statements and, in our
    opinion, fairly states in all material respects the consolidated
    financial data required to be set forth therein in relation to the basic
    consolidated financial statements taken as a whole.

             Loans  : Loans  extended to  Key Employees  by the  Company
        pursuant to this Plan.

             Plan : The ThermoTrex Corporation Stock Holding  Assistance
        Plan, as amended from time to time.

        SECTION 3.     Administration.

             The Plan and the Stock Holding Policy shall be  administered
        by the Committee,  which shall  have authority  to interpret  the
        Plan  and  the  Stock  Holding  Policy  and,  subject  to   their
        provisions,  to  prescribe,  amend  and  rescind  any  rules  and
        regulations and  to make  all other  determinations necessary  or
        desirable  for  the  administration  thereof.    The  Committee's
PAGE
<PAGE>
        interpretations and decisions  with regard  to the  Plan and  the
        Stock Holding Policy  and such  rules and regulations  as may  be
        established thereunder  shall  be  final  and  conclusive.    The
        Committee may  correct  any  defect or  supply  any  omission  or
        reconcile any  inconsistency in  the Plan  or the  Stock  Holding
        Policy, or  in any  Loan in  the  manner and  to the  extent  the
        Committee deems desirable to carry it into effect.  No member  of
        the Committee  shall be  liable  for any  action or  omission  in
        connection with the Plan or the Stock Holding Policy that is made
        in good faith.

        SECTION 4.     Loans and Loan Limits.

             The Committee  has determined  that the  provision of  Loans
        from time to time  to Key Employees in  such amounts as to  cause
        such Key Employees to comply with the Stock Holding Policy is, in
        the judgment of the Committee, reasonably expected to benefit the
        Company and authorizes the Company  to extend Loans from time  to
        time to Key Employees in such amounts as may be requested by such
        Key Employees in order to  comply with the Stock Holding  Policy.
        Such Loans may be used solely for the purpose of acquiring Common
        Stock (other than  upon the  exercise of stock  options or  under
        employee stock  purchase plans)  in open  market transactions  or
        from the Company.

             Each  Loan  shall  be  full  recourse  and  evidenced  by  a
        non-interest bearing promissory  note substantially  in the  form
        attached hereto  as  Exhibit A       (the  "Note")  and  maturing
        accordance  with  the  provisions   of  Section  6  hereof,   and
        containing  such  other  terms  and  conditions,  which  are  not
        inconsistent with  the  provisions  of the  Plan  and  the  Stock
        Holding Policy, as the Committee shall determine in its sole  and
        absolute discretion.

        SECTION 5.     Federal Income Tax Treatment of Loans.

             For federal income tax purposes, interest on Loans shall  be
        imputed on any interest free Loan extended under the Plan.  A Key
        Employee shall be deemed to have paid the imputed interest to the
        Company and the Company shall be deemed to have paid said imputed
        interest back  to the  Key Employee  as additional  compensation.
        The deemed interest payment  shall be taxable  to the Company  as
        income, and may be deductible to  the Key Employee to the  extent
        allowable under the rules relating  to investment interest.   The
        deemed compensation payment to the Key Employee shall be  taxable
        to the employee and deductible to the Company, but shall also  be
        subject to employment taxes such as FICA and FUTA.

        SECTION 6.     Maturity of Loans.

             Each Loan  to a  Key  Employee hereunder  shall be  due  and
        payable on demand  by the Company.   If no  such demand is  made,
        then each  Loan  shall mature  and  the principal  thereof  shall
        become due and payable in five equal annual installments from the

                                        2PAGE
<PAGE>
        payment of  annual cash  incentive compensation  (referred to  as
        bonus) to the  Key Employee  by the Company,  beginning with  the
        first such bonus  payment to  occur after  the date  of the  Note
        evidencing the Loan, and on each  of the next four bonus  payment
        dates.  Each Loan shall  also become immediately due and  payable
        in full,  without demand,  upon   the occurrence  of any  of  the
        events set forth in the Note; provided that the Committee may, in
        its sole and absolute discretion,  authorize an extension of  the
        time for repayment of  a Loan upon such  terms and conditions  as
        the Committee may determine.

        SECTION 7.     Amendment and Termination of the Plan.

             The Committee may from time to time alter or amend the  Plan
        or the Stock Holding Policy in any respect, or terminate the Plan
        or the Stock Holding  Policy at any time.   No such amendment  or
        termination, however, shall alter  or otherwise affect the  terms
        and conditions  of  any Loan  then  outstanding to  Key  Employee
        without such Key Employee's written consent, except as  otherwise
        provided herein or in the promissory note evidencing such Loan.

        SECTION 8.     Miscellaneous Provisions.

             (a)  No employee or  other person  shall have  any claim  or
        right to receive  a Loan under  the Plan, and  no employee  shall
        have any right to be retained in the employ of the Company due to
        his or her participation in the Plan.

             (b)  No Loan shall be made hereunder unless counsel for  the
        Company shall be satisfied that  such Loan will be in  compliance
        with applicable federal, state and local laws.

             (c)  The expenses of the Plan shall be borne by the Company.

             (d)  The Plan shall be unfunded,  and the Company shall  not
        be required to establish any special or separate fund or to  make
        any other segregation of assets to assure the making of any  Loan
        under the Plan.

             (e)  Except as otherwise  provided in Section  7 hereof,  by
        accepting any Loan  under the  Plan, each Key  Employee shall  be
        conclusively  deemed  to  have   indicated  his  acceptance   and
        ratification of, and consent to, any action taken under the  Plan
        or the  Stock  Holding  Policy  by  the  Company,  the  Board  of
        Directors of the Company or the Committee.

             (f)  The appropriate officers of the Company shall cause  to
        be filed  any reports,  returns  or other  information  regarding
        Loans hereunder, as  may be required  by any applicable  statute,
        rule or regulation.

        SECTION 9.     Effective Date.

        $_________                                                       
                                                Dated:____________


             For value  received, ________________,  an individual  whose
        residence is located at _______________________ (the "Employee"),
        hereby promises to pay to ThermoTrex Corporation (the "Company"),
        or assigns, ON DEMAND, but in any case on or before [insert  date
        which  is  the  fifth  anniversary  of  date  of  issuance]  (the
        "Maturity Date"), the  principal sum  of [loan  amount in  words]
        ($_______), or such part thereof as then remains unpaid,  without
        interest.   Principal shall  be payable  in lawful  money of  the
        United States of America, in immediately available funds, at  the
        principal office of  the Company or  at such other  place as  the
        Company may  designate  from  time  to time  in  writing  to  the
        Employee. 

              Unless the Company has already made a demand for payment in
        full of this Note, the Employee  agrees to repay the Company   an
        amount equal to 20% of the  initial principal amount of the  Note
        from the payment of annual cash incentive compensation  (referred
        to as bonus) to the Employee  by the Company, beginning with  the
        first such bonus payment  to occur after the  date of this  Note,
        and on each  of the next  four bonus payment  dates.  Any  amount
        remaining unpaid under this Note, if  no demand has been made  by
        the Company, shall be due and payable on the Maturity Date.

             This Note may be prepaid at  any time or from time to  time,
        in whole  or  in part,  without  any  premium or  penalty.    The
        Employee acknowledges and agrees that the Company has advanced to
        the Employee the principal  amount of this  Note pursuant to  the
        Company's Stock Holding Assistance Plan,  and that all terms  and
        conditions of such Plan are incorporated herein by reference.  

             The unpaid principal amount of this Note shall be and become
        immediately due  and payable  without notice  or demand,  at  the
        option of  the  Company,  upon  the  occurrence  of  any  of  the
        following events:

                  (a)  the termination of the Employee's employment  with
             the Company, with or without cause, for any reason or for no
             reason;

                  (b)  the death or disability of the Employee;

<PAGE>
                  (c)  the failure  of the  Employee to  pay his  or  her
             debts as they  become due, the  insolvency of the  Employee,
             the filing by or against the Employee of any petition  under
             the United  States Bankruptcy  Code (or  the filing  of  any
             similar  petition   under   the  insolvency   law   of   any
             jurisdiction),  or  the  making   by  the  Employee  of   an
             assignment or trust mortgage for the benefit of creditors or
             the appointment of  a receiver, custodian  or similar  agent
             with respect  to,  or  the  taking by  any  such  person  of
             possession of, any property of the Employee; or

                  (d)  the issuance of any writ of attachment, by trustee
             process or otherwise, or any restraining order or injunction
             not removed, repealed or  dismissed within thirty (30)  days
             of issuance, against or affecting the person or property  of
             the Employee or any liability or obligation of the  Employee
             to the Company.

             In case any payment  herein provided for  shall not be  paid
        when due,  the Employee  further  promises to  pay all  costs  of
        collection, including all reasonable attorneys' fees.

             No  delay  or  omission  on  the  part  of  the  Company  in
        exercising any right hereunder shall operate as a waiver of  such
        right or of any other right of the Company, nor shall any  delay,
        omission or waiver  on any  one occasion be  deemed a  bar to  or
        waiver of the  same or any  other right on  any future  occasion.
        The  Employee  hereby  waives  presentment,  demand,  notice   of
        prepayment,  protest  and  all  other  demands  and  notices   in
        connection with the delivery, acceptance, performance, default or
        enforcement of this Note.  The undersigned hereby assents to  any
        indulgence  and  any  extension  of  time  for  payment  of   any
        indebtedness  evidenced  hereby  granted  or  permitted  by   the
        Company.  

             This Note  has been  made pursuant  to the  Company's  Stock
        Holding Assistance Plan and shall be governed by and construed in
        accordance with, such Plan and the laws of the State of  Delaware
        and shall have the effect of a sealed instrument.

    Notes to Consolidated Financial Statements

    1.   Nature of Operations and Summary of Significant Accounting Policies

    Nature of Operations

         ThermoTrex Corporation (the Company) develops and markets medical
    products and personal-care products and services, and also performs
    advanced technology research. The Company's 80%-owned Trex Medical
    Corporation (Trex Medical) subsidiary designs, manufactures, and markets

    mammography equipment and minimally invasive stereotactic breast-biopsy
    systems used for the detection of breast cancer, general radiography
    (X-ray) equipment, and X-ray imaging systems used for cardiac
    catheterization and angiography, as well as radiographic fluoroscopy. The
    Company's 64%-owned ThermoLase Corporation (ThermoLase) subsidiary has
    developed a laser-based system called SoftLight(SM) for the removal of
    unwanted hair, and also markets skin-care, bath, and body products
    through its wholly owned CBI Laboratories, Inc. (CBI) subsidiary. The
    Company concentrates its advanced technology research efforts in the
    areas of communications, avionics, X-ray detection, signal processing,
    advanced-materials technology, and lasers. The Company has developed its
    expertise in these core technologies in connection with government-
    sponsored research and development.


    Relationship with Thermo Electron Corporation

         The Company was incorporated in January 1991, as a wholly owned
    subsidiary of Thermo Electron Corporation (Thermo Electron). As of
    September 28, 1996, Thermo Electron owned 9,711,282 shares of the
    Company's common stock, representing 51% of such stock outstanding.

    Principles of Consolidation

         The accompanying financial statements include the accounts of the
    Company, its wholly owned subsidiary, and its publicly held ThermoLase
    and Trex Medical subsidiaries. All material intercompany accounts and
    transactions have been eliminated.

    Fiscal Year

         In September 1995, the Company changed its fiscal year end from the
    Saturday nearest December 31 to the Saturday nearest September 30.
    Accordingly, the Company's transition period, which ended on September
    30, 1995, was the 39-week period from January 1, 1995 to September 30,
    1995, referenced as "fiscal 1995." References to "fiscal 1996" and "1994"
    are for the years ended September 28, 1996 and December 31, 1994,
    respectively. Fiscal 1996 and 1994 each included 52 weeks. The unaudited
    consolidated statements of income and cash flows for the 52-week period
    ended September 30, 1995 are presented for comparative purposes only.

    Revenue Recognition

         The Company recognizes product revenues upon shipment of its
    products. The Company provides a reserve for its estimate of warranty
    costs at the time of shipment. The Company recognizes revenues from
    hair-removal services performed at ThermoLase's Spa Thira salons over the
                                       10PAGE

    ThermoTrex Corporation
    Notes to Consolidated Financial Statements

    1.   Nature of Operations and Summary of Significant Accounting Policies
         (continued)

    anticipated treatment period.  Revenues from hair-removal treatments
    performed by ThermoLase's network of independent doctors are also
    recognized over the anticipated treatment period. Nonrefundable minimum
    licensing fees are recorded when earned. The Company recognizes contract
    revenues and profits using the percentage-of-completion method. The
    percentage of completion is determined by relating the actual costs
    incurred to date to management's estimate of total costs to be incurred
    on each contract. If a loss is indicated on any contract in process, a
    provision is made currently for the entire loss. The Company's contracts
    are generally cost-plus-fixed-fee, and customers are billed monthly as
    costs are incurred. Revenues earned on contracts in process in excess of
    billings are classified as "Unbilled contract costs and fees" in the
    accompanying balance sheet. There are no significant amounts included in
    the accompanying balance sheet that are not expected to be recovered from
    existing contracts at current contract values, or that are not expected
    to be collected within one year.

    Research and Development Expenses

         Costs classified as research and development expenses in the
    accompanying statement of income are costs incurred in connection with
    internally funded programs, including independent research and
    development as defined by U.S. government procurement regulations.
    Included in cost of contract revenues in the accompanying statement of
    income are research and development costs incurred under U.S.
    government-funded contracts. 

    Gain on Issuance of Stock by Subsidiaries

         At the time a subsidiary sells its stock to unrelated parties at a
    price in excess of its book value, the Company's net investment in that
    subsidiary increases. If at that time the subsidiary is an operating
    entity and not engaged principally in research and development, the
    Company records the increase as a gain. See Note 11 for a description of
    gains recorded.

         If gains have been recognized on the issuance of a subsidiary's
    stock and shares of the subsidiary are subsequently repurchased either by
    the subsidiary, the Company, or Thermo Electron, gain recognition does
    not occur on issuances subsequent to the date of a repurchase until such
    time as shares have been issued in an amount equivalent to the number of
    repurchased shares.

    Concentration of Credit Risk

         The Company's Trex Medical subsidiary sells its products primarily
    to customers in the healthcare industry. Trex Medical does not normally
    require collateral or other security to support its accounts receivable.
    Management does not believe that this concentration of credit risk has,
    or will have, a significant negative impact on the Company.

         (continued)

    Income Taxes

         In accordance with Statement of Financial Accounting Standards
    (SFAS) No. 109, "Accounting for Income Taxes," the Company recognizes
    deferred income taxes based on the expected future tax consequences of
    differences between the financial statement basis and the tax basis of
    assets and liabilities calculated using enacted tax rates in effect for
    the year in which the differences are expected to be reflected in the tax
    return.

    Earnings per Share

         Earnings per share have been computed based on the weighted average
    number of shares outstanding during the period. In fiscal 1996 and 1994,
    weighted average shares include the effect of the exercise of stock
    options that were computed using the treasury stock method. During fiscal
    1995, the effect of the exercise of stock options was not material.

    Cash and Cash Equivalents

         As of September 28, 1996, $40,727,000 of the Company's cash
    equivalents were invested in a repurchase agreement with Thermo Electron.
    Under this agreement, the Company in effect lends excess cash to Thermo
    Electron, which Thermo Electron collateralizes with investments
    principally consisting of corporate notes, U.S. government agency
    securities, money market funds, commercial paper, and other marketable
    securities, in the amount of at least 103% of such obligation. The
    Company's funds subject to the repurchase agreement are readily
    convertible into cash by the Company. The repurchase agreement earns a
    rate based on the 90-day Commercial Paper Composite Rate plus 25 basis
    points, set at the beginning of each quarter. As of September 28, 1996,
    the Company's cash equivalents also include money market fund
    investments. Cash equivalents are carried at cost, which approximates
    market value.

    Available-for-sale Investments

         Pursuant to SFAS No. 115, "Accounting for Certain Investments in
    Debt and Equity Securities," the Company's debt and marketable equity
    securities are accounted for at market value (Note 3).

    Inventories

         Inventories are stated at the lower of cost (on a first-in,
    first-out basis) or market value and include materials, labor, and
    manufacturing overhead. The components of inventories are as follows:

    Property, Plant and Equipment

         The costs of additions and improvements are capitalized, while
    maintenance and repairs are charged to expense as incurred. The Company
    provides for depreciation and amortization principally using the
    straight-line method over the estimated useful lives of the property as
    follows: buildings - 29 to 31.5 years; machinery and equipment - 3 to 10
    years; and leasehold improvements - the shorter of the term of the lease
    or the life of the asset. Property, plant and equipment consist of the
    following:

    Other Assets

         In June 1996, ThermoLase purchased $4,400,000 of convertible
    preferred stock of AntiCancer Incorporated (AntiCancer), representing an
    approximate 10% equity interest in AntiCancer on a fully diluted basis.
    AntiCancer is a San Diego-based company that is developing a new

    chemotherapeutic drug for cancer patients, and that is also developing
    certain technologies that may be relevant to ThermoLase's SoftLight
    hair-removal process and other personal-care applications. ThermoLase has
    the option to purchase for $2,500,000 an additional 5% equity interest in
    AntiCancer on a fully diluted basis, exercisable at any time before the
    earlier of June 19, 2011, or AntiCancer's initial public offering of
    stock. This investment is being accounted for under the cost method of
    accounting. In addition, ThermoLase has licensed certain technology from
    AntiCancer (Note 10).

    Cost in Excess of Net Assets of Acquired Companies

         The excess of cost over the fair value of net assets of acquired
    companies is amortized using the straight-line method over 40 years.
    Accumulated amortization was $5,434,000 and $3,353,000 at September 28,
    1996 and September 30, 1995, respectively. The Company assesses the
    future useful life of this asset whenever events or changes in
    circumstances indicate that the current useful life has diminished. The
    Company considers the future undiscounted cash flows of the acquired
    businesses in assessing the recoverability of this asset.

    Deferred Lease Liability

         Deferred lease liability in the accompanying balance sheet
    represents facilities rent which is being recognized ratably over the
    respective lease terms.

    Fair Value of Financial Instruments

         The Company's financial instruments consist primarily of cash and
    cash equivalents, available-for-sale investments, accounts receivable,
    note payable to parent company, accounts payable, and due to parent
    company and affiliates. The carrying amounts of the Company's cash and
    cash equivalents, accounts receivable, note payable to parent company,
    accounts payable, and due to parent company and affiliates approximate
    fair value due to their short-term nature. Available-for-sale investments
    are carried at fair value in the accompanying balance sheet. The fair
    values were determined based on quoted market prices. See Note 3 for
    information pertaining to the fair value of available-for-sale
    investments.

    Use of Estimates

    generally accepted accounting principles requires management to make
    estimates and assumptions that affect the reported amounts of assets and
    liabilities, 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.

    Presentation

         Certain amounts in fiscal 1995 and 1994 have been reclassified to
    conform to the presentation in the fiscal 1996 financial statements.

    3.   Available-for-sale Investments

         Effective January 2, 1994, the Company adopted SFAS No. 115,
    "Accounting for Certain Investments in Debt and Equity Securities." In
    accordance with SFAS No. 115, the Company's debt and marketable equity
    securities are classified as available-for-sale investments in the
    accompanying balance sheet and are carried at market value, with the
    difference between cost and market value, net of related tax effects,
    recorded currently as a component of shareholders' investment titled "Net
    unrealized loss on available-for-sale investments." Effect of change in
    accounting principle in the accompanying 1994 statement of shareholders'
    investment represents the unrealized gain, net of related tax effects,
    pertaining to available-for-sale investments held by the Company on
    January 2, 1994.

         The aggregate market value, cost basis, and gross unrealized gains
    and losses of available-for-sale investments, by major security type, as
    of September 28, 1996 and September 30, 1995, are as follows:

         Available-for-sale investments in the accompanying 1996 balance
    sheet include $36,609,000 with contractual maturities of one year or less
    and $15,092,000 with contractual maturities of more than one year through
    five years. Actual maturities may differ from contractual maturities as a
    result of the Company's intent to sell these securities prior to maturity
    and as a result of put and call options that enable the Company and/or
    the issuer to redeem these securities at an earlier date.

    3.   Available-for-sale Investments (continued)

         The cost of available-for-sale investments that were sold was based
    on specific identification in determining realized gains and losses
    recorded in the accompanying statement of income. Gain on sale of
    investments in the accompanying statement of income for fiscal 1996 and
    fiscal 1995 represents the gross realized gains relating to the sale of
    available-for-sale investments. Loss on sale of investments in the
    accompanying 1994 statement of income resulted from gross realized gains
    of $54,000 and gross realized losses of $71,000 relating to the sale of
    available-for-sale investments.


    4.   Acquisitions and Joint Venture

    Acquisitions

         In September 1996, Trex Medical acquired substantially all of the
    assets and liabilities of Continental X-Ray Corporation and affiliates
    (Continental) for approximately $18.4 million in cash, net of cash
    acquired and including the repayment of debt. Continental designs,
    manufactures, and markets general-purpose and specialized X-ray systems.

         In May 1996, Trex Medical acquired  substantially all of the assets
    and liabilities of XRE Corporation (XRE) for $18.5 million in cash, net
    of cash acquired and including the repayment of debt. XRE designs,
    manufactures, and markets X-ray imaging systems used in the diagnosis and
    treatment of coronary artery disease and other vascular conditions.

         In September 1995, the Company acquired all of the outstanding
    capital stock of Bennett X-Ray Corporation (Bennett) for approximately
    $42.9 million in cash. In conjunction with the capitalization of Trex
    Medical, the Company transferred to Trex Medical all of the outstanding
    stock of Bennett in October 1995. Bennett manufactures high-frequency
    specialty and general-purpose X-ray systems.

         These acquisitions have been accounted for using the purchase
    method of accounting, and their results of operations have been included
    in the accompanying financial statements from their respective dates of
    acquisition. The aggregate cost of these acquisitions exceeded the
    estimated fair value of the acquired net assets by $64.0 million, which
    is being amortized over 40 years. Allocation of the purchase price for
    these acquisitions was based on estimates of the fair value of the net
    assets acquired and, for Continental and XRE, is subject to adjustment
    upon finalization of the purchase price allocation. To date, no
    information has been gathered that would cause the Company to believe
    that the final allocation of the purchase price will be materially
    different from the preliminary estimate.

    4.   Acquisitions and Joint Venture (continued)

         Based on unaudited data, the following table presents selected
    financial information for the Company and Bennett on a pro forma basis,
    assuming that Bennett had been purchased at the beginning of 1994. The
    pro forma data does not include Continental or XRE, since these
    acquisitions were not material to the Company's results of operations or
    financial position.

                                              Nine Months
    (In thousands except                         Ended         Year Ended
    per share amounts)                      Sept. 30, 1995    Dec. 31, 1994
    -----------------------------------------------------------------------
    Revenues                                  $117,332          $133,585
    Net income                                  35,790             7,107
    Earnings per share                            1.89               .37

         The pro forma results are not necessarily indicative of future
    operations or the actual results that would have occurred had the
    acquisition of Bennett been made at the beginning of 1994.

         In November 1992, the Company acquired Lorad for $5.3 million in
    cash, assumption of $6.7 million of pre-existing debt of Lorad, and
    shares of the Company's common stock and stock options valued at $12.3
    million. In addition, in March 1995, the Company made a cash payment of
    $2.3 million to the holders of approximately 9.2% of Lorad's common stock
    who had earlier voted against the acquisition, in exchange for their
    interest in Lorad.

         Other accrued expenses in the accompanying balance sheet include
    $3.5 million at September 28, 1996 and $4.0 million at September 30, 1995
    for estimated reserves associated with acquisitions, including a reserve
    of approximately $2 million for legal fees and other costs associated
    with a patent infringement suit that existed prior to the Company's
    acquisition of Lorad. This suit was brought by Fischer Imaging
    Corporation (Fischer), which alleges that Lorad infringes on a Fischer
    patent on a precision mammographic needle-biopsy system. While the
    Company believes it has meritorious legal defenses to the allegation, due
    to the inherent uncertainties of litigation, the Company is unable to
    predict the outcome of this matter. Although an unsuccessful resolution
    could have a material adverse effect on the Company's results of
    operations, in the opinion of management any resolution will not have a
    material adverse effect on the Company's financial position.

    Joint Venture

         In January 1996, ThermoLase entered into a joint venture agreement
    and a technology license agreement to market its SoftLight system in
    Japan. ThermoLase currently holds a 50% stake in the joint venture but
    may increase its ownership to 51% pursuant to a fair-value purchase
    option. Under the terms of the joint venture agreement, ThermoLase will
    receive payments for the use of the SoftLight system equal to 2% of the
    joint venture's revenues through calendar year 2010, subject to minimum
    guaranteed payments totaling $3,000,000, of which $2,000,000 was received

    4.   Acquisitions and Joint Venture (continued)

    in fiscal 1996. The remaining $1,000,000 is due in fiscal 1997, subject
    to certain exceptions in the event the joint venture is unable to obtain
    patent protection in Japan on prescribed terms. If cumulative licensing
    fees paid to the Company exceed $50,000,000, the rate will decrease to
    .25% through calendar year 2010. Starting in calendar year 2011, the rate
    will be 1%.


    5.   Common Stock

         In March 1994, the Company sold 1,610,000 shares of its common
    stock at $15.375 per share in a public offering for net proceeds of
    $23,034,000.

         As of September 28, 1996, the Company had reserved 2,066,646
    unissued shares of its common stock for possible issuance under
    stock-based compensation plans.


    6.   Stock-based Compensation Plans

         The Company has stock-based compensation plans for its key
    employees, directors, and others. Two of these plans, adopted in 1990,
    permit the grant of nonqualified and incentive stock options. The option
    recipients and the terms of options granted under these plans are
    determined by the human resources committee of the Company's Board of
    Directors (the Board Committee). Generally, options granted to date are
    exercisable immediately, but are subject to certain transfer restrictions
    and the right of the Company to repurchase shares issued upon exercise of
    the options at the exercise price, upon certain events. The restrictions
    and repurchase rights generally lapse ratably over periods ranging from
    five to ten years after the first anniversary of the grant date,
    depending on the term of the option, which may range from seven to twelve
    years. Nonqualified stock options may be granted at any price determined
    by the Board Committee, although incentive stock options must be granted
    at not less than the fair market value of the Company's stock on the date
    of grant. To date, with the exception of the options granted in
    connection with the acquisition of Lorad (Note 4), all options have been
    granted at fair market value. The Company also has a directors' stock
    option plan, adopted in 1991 and amended in fiscal 1995, that provides
    for the grant of stock options in the Company and its majority-owned
    subsidiaries to nonemployee directors pursuant to a formula approved by
    the Company's shareholders. Options in the Company awarded under this
    plan are exercisable six months after the date of grant and expire three
    or seven years after the date of grant. In addition to the Company's
    stock-based compensation plans, certain officers and key employees may
    also participate in stock-based compensation plans of Thermo Electron or
    its majority-owned subsidiaries.

   6.   Stock-based Compensation Plans (continued)

        No accounting recognition is given to options granted at fair market
   value until they are exercised. Upon exercise, net proceeds, including tax
   benefits realized, are credited to equity. A summary of the Company's stock
   option information for fiscal 1996, fiscal 1995, and 1994 is as follows:

   7.   Employee Benefit Plans

   Employee Stock Purchase Plan

        Substantially all of the Company's full-time employees are eligible
   to participate in the Company's employee stock purchase plan. Under this
   plan, shares of the Company's and Thermo Electron's common stock can be
   purchased at the end of a 12-month plan year at 95% of the fair market
   value at the beginning of the plan year, and the shares purchased are
   subject to a six-month resale restriction. Prior to November 1, 1995, the
   applicable shares of common stock could be purchased at 85% of the fair
   market value at the beginning of the plan year, and the shares purchased
   were subject to a one-year resale restriction. Shares are purchased through
   payroll deductions of up to 10% of each participating employee's gross
   wages. During fiscal 1996 and 1994, the Company issued 25,792 shares and
   29,744 shares of its common stock, respectively, under this plan. No shares
   were issued under this plan during fiscal 1995.

    7.   Employee Benefit Plans (continued)

    401(k) Savings Plan and Employee Stock Ownership Plan

         The majority of the Company's full-time employees are eligible to
    participate in Thermo Electron's 401(k) savings plan and, prior to
    January 1, 1995, in Thermo Electron's employee stock ownership plan
    (ESOP). Contributions to the 401(k) savings plan are made by both the
    employee and the Company. Company contributions are based upon the level
    of employee contributions. For these plans, the Company contributed and
    charged to expense $1,166,000, $653,000, and $679,000 in fiscal 1996,
    fiscal 1995, and 1994, respectively. Effective December 31, 1994, the
    ESOP was split into two plans: ESOP I, covering employees of Thermo
    Electron's corporate office and its wholly owned subsidiaries and ESOP
    II, covering employees of certain of Thermo Electron's majority-owned
    subsidiaries, including the Company. Also, effective December 31, 1994,
    the ESOP II plan was terminated, and as a result, the Company's employees
    are no longer eligible to participate in an ESOP.


    8.   Income Taxes

         The components of the provision for income taxes for fiscal 1996,
    fiscal 1995, and 1994 are as follows:

         The Company receives a tax deduction upon exercise of nonqualified
    stock options by employees for the difference between the exercise price
    and the market price of the Company's common stock on the date of
    exercise. The provision for income taxes that is currently payable does
    not reflect $2,680,000, $2,217,000, and $945,000 of such benefits of the
    Company and its majority-owned subsidiaries from employee exercises of
    stock options that have been allocated to capital in excess of par value,
    directly or through the effect of majority-owned subsidiaries' equity
    transactions in fiscal 1996, fiscal 1995, and 1994, respectively.

    8.   Income Taxes (continued)

         The provision for income taxes in the accompanying statement of
    income differs from the provision calculated by applying the statutory
    federal income tax rate of 35% in fiscal 1996 and 34% in fiscal 1995 and
    1994 to income before provision for income taxes and minority interest
    due to the following:

         The year-end 1996 valuation allowance relates to employee exercises
    of stock options for which no tax benefit was recognized, and will be
    used to increase capital in excess of par value when the net operating
    loss is realized. The year-end 1995 valuation allowance related primarily
    to the uncertainty surrounding the realization of future tax benefits
    associated with acquisition reserves related to Lorad, CBI, and Bennett
    (Note 4). Due to decreased uncertainty concerning the realizability of
    this amount, the year-end 1995 valuation allowance related to these
    reserves was reversed through a reduction of cost in excess of net assets
    of acquired companies. As of September 28, 1996, ThermoLase had federal
    tax net operating loss carryforwards of $6,184,000 that begin to expire
    in fiscal 2009.

    8.   Income Taxes (continued)

         The Company has not recognized a deferred tax liability for the
    difference between the book basis and tax basis of the common stock of
    its domestic subsidiaries (such difference relates primarily to
    unremitted earnings and gains on issuance of stock by subsidiaries)
    because the Company does not expect this basis difference to become
    subject to tax at the parent level. The Company believes it can implement
    certain tax strategies to recover its investment in its domestic
    subsidiaries tax-free.


    9.    Related Party Transactions

    Corporate Services Agreement

         The Company and Thermo Electron have a corporate services agreement
    under which Thermo Electron's corporate staff provides certain
    administrative services, including certain legal advice and services,
    risk management, certain employee benefit administration, tax advice and
    preparation of tax returns, centralized cash management, and certain
    financial and other services, for which the Company pays Thermo Electron
    annually an amount equal to 1.0% of the Company's revenues. The Company
    paid an annual fee equal to 1.20% and 1.25% of the Company's revenues in
    calendar year 1995 and 1994, respectively. The annual fee is reviewed and
    adjusted annually by mutual agreement of the parties. For these services,
    the Company was charged $1,906,000, $1,038,000, and $1,138,000 in fiscal
    1996, fiscal 1995, and 1994, respectively. Management believes that the
    service fee charged by Thermo Electron is reasonable and that such fees
    are representative of the expenses the Company would have incurred on a
    stand-alone basis. The corporate services agreement is renewed annually
    but can be terminated upon 30 days' prior notice by the Company or upon
    the Company's withdrawal from the Thermo Electron Corporate Charter (the
    Thermo Electron Corporate Charter defines the relationships among Thermo
    Electron and its majority-owned subsidiaries). For additional items such
    as employee benefit plans, insurance coverage, and other identifiable
    costs, Thermo Electron charges the Company based upon costs attributable
    to the Company.

    Other Related Party Services

         Data processing services and, as of January 1995, contract
    administration, are provided to the Company by a majority-owned
    subsidiary of Thermo Electron and are charged to the Company based on
    actual usage. For these services, the Company was charged $90,000,
    $139,000, and $72,000 in fiscal 1996, fiscal 1995, and 1994,
    respectively.

         Prior to January 1995, the Company provided contract administration
    services to Thermo Electron and two of Thermo Electron's majority-owned
    subsidiaries, which were charged based on actual usage. For these
    services, the Company charged $191,000 in 1994.

    9.    Related Party Transactions (continued)

    Operating Leases

         Until June 1996, the Company leased two office and research
    facilities from Thermo Electron. In connection with the Company's
    decision to close its Waltham, Massachusetts division (Note 12) and
    because Thermo Electron desires to sell these facilities, the Company  
    agreed to vacate these facilities during fiscal 1996. In addition, the
    Company leases an office and manufacturing facility from a realty trust
    controlled by an employee under a noncancellable operating lease
    arrangement expiring in fiscal 2012. The accompanying statement of income
    includes expenses from this operating lease of $375,000 in fiscal 1996.
    Future minimum payments due under this noncancellable operating lease as
    of September 28, 1996, are $858,000 per year in fiscal 1997, 1998, 1999,
    and 2000; $897,000 in fiscal 2001; and $11,102,000 in fiscal 2002 and
    thereafter. Total future minimum lease payments are $15,431,000.

    Repurchase Agreement

         The Company invests excess cash in a repurchase agreement with
    Thermo Electron as discussed in Note 1.

    Notes Receivable from Related Party

         During fiscal 1995 and fiscal 1996, the Company loaned $2,000,000
    and $1,300,000, respectively, to Dolphin Acquisition Corporation
    (Dolphin). Borrowings bear interest at an annual rate of 6.0% and are due
    in June 2000. Dolphin operates a retail chain of beauty product stores in
    California and other states within the United States. The president of
    ThermoLase is a shareholder and former officer of Dolphin.

    Note Payable to Parent Company

         In September 1995, the Company borrowed $8,000,000 from Thermo
    Electron pursuant to a promissory note bearing interest at the 90-day
    Commercial Paper Composite Rate plus 25 basis points. This note was
    repaid in September 1996. In September 1996, the Company borrowed
    $2,000,000 from Thermo Electron pursuant to a promissory note, due April
    30, 1997, and bearing interest at the 90-day Commercial Paper Composite
    Rate plus 25 basis points.

    Related Party Revenues

         Under an arrangement with Thermedics Detection Inc., a
    majority-owned subsidiary of Thermedics Inc., a publicly traded,
    majority-owned subsidiary of Thermo Electron, Trex Medical manufactures
    an X-ray source, pursuant to written purchase orders, that is used as a
    component to a fill-measuring device produced by Thermedics Detection
    Inc. During fiscal 1996 and fiscal 1995, Trex Medical recorded $361,000
    and $120,000, respectively, of revenue under this agreement.

    Vendor Agreement

         During fiscal 1995, Trex Medical placed an order for $2,500,000 for
    the design and production of high-transmission cellular grids from Thermo
    Electron's Tecomet division (Tecomet), which will be received through
    fiscal 1997. During fiscal 1996, the Company purchased grids valued at
    $397,000 from Tecomet under this arrangement. In addition, Trex Medical
    recorded expense of $250,000 during each of fiscal 1996 and fiscal 1995
    related to research and development funding provided to Tecomet in
    connection with this project.

    Sale of Thermoelectrics and Thermionics Businesses

         During fiscal 1996, the Company sold its thermoelectrics and
    thermionics businesses to two subsidiaries of Thermo Electron. The
    selling price for these companies of approximately $860,000, subject to a
    post-closing adjustment, was based on the net book value of the net
    assets transferred. These businesses were not material to the Company's
    results of operations or financial position.


    10.  Commitments and Contingencies

    Operating Leases

         In addition to the leases described in Note 9, the Company occupies
    office, research, manufacturing, and service facilities under various
    noncancellable operating lease arrangements that expire at various dates
    through 2006. The accompanying statement of income includes expenses from
    these operating leases of $2,253,000, $794,000, and $1,010,000 in fiscal
    1996, fiscal 1995, and 1994, respectively. Future minimum payments due
    under these noncancellable operating leases as of September 28, 1996, are
    $4,017,000 in fiscal 1997; $4,188,000 in fiscal 1998; $4,178,000 in
    fiscal 1999; $4,285,000 in fiscal 2000; $4,547,000 in fiscal 2001; and
    $19,508,000 in fiscal 2002 and thereafter. Total future minimum lease
    payments are $40,723,000.

    Technology License Agreement

         ThermoLase has licensed from AntiCancer (Note 1) certain technology
    related to hair removal, stimulation of hair growth, suppression of hair
    growth, and hair coloring under an agreement that calls for up to
    $1,500,000 in future payments by ThermoLase upon the attainment of
    certain milestones by AntiCancer. In addition to such future payments,
    ThermoLase will be substantially responsible for development costs
    incurred after attainment of such milestones. In the event that the
    funded development efforts result in commercially viable products,
    ThermoLase will pay AntiCancer a royalty based on sales, subject to
    certain minimum payments.

    Notes to Consolidated Financial Statements

    10.  Commitments and Contingencies (continued)

    Contingencies

         ThermoLase has from time to time received allegations that its
    patented SoftLight laser-based system for the removal of unwanted hair
    infringes the intellectual property rights of others, and ThermoLase may
    continue to receive such allegations in the future. In general, an owner
    of intellectual property can prevent others from using such property
    without a license and is entitled to damages for unauthorized past usage.
    The Company has investigated the bases of the allegations ThermoLase has
    received to date and, based on opinions of its counsel, believes that if
    ThermoLase were sued on these bases it would have meritorious defenses.

         The owner of a U.S. patent related to Trex Medical's automatic
    exposure control has claimed that the Company's mammography systems
    infringe such patent. The patent owner has offered a nonexclusive license
    under the patent on terms not acceptable to the Company. Although the
    Company believes that the validity of the patent may be questionable and
    subject to a successful challenge, if the patent holder were successful
    in enforcing such patent the Company could be enjoined from manufacturing
    and selling mammography systems. In addition, the Company is aware of two
    U.S. patents owned by a former employee which have been asserted against
    the Company relating to its High-Transmission Cellular (HTC)(TM) grid to
    be used with the Company's mammography systems. Although the Company
    believes that the HTC grid does not infringe either of these patents, if
    the holder of the patents were successful in enforcing such patents, the
    Company could be subject to damages and enjoined from manufacturing and
    selling the HTC grid.

         See Note 4 for a discussion of certain additional litigation.

         Due to the inherent uncertainty of dispute resolution, management
    cannot predict the outcome of these matters. While an unfavorable outcome
    of one or more of these matters could have a material adverse effect on
    the Company's results of operations, in the opinion of management any
    resolution will not have a material effect on the Company's financial
    position.


    11.  Transactions in Stock of Subsidiaries

         In July 1996, Trex Medical issued 2,875,000 shares of its common
    stock in an initial public offering, and 871,832 shares of its common
    stock in a concurrent rights offering, at $14.00 per share, for net
    proceeds of $49,069,000, resulting in a gain of $25,645,000.


         In January 1996, Trex Medical issued 100,000 shares of its common
    stock in a private placement at $10.75 per share for net proceeds of
    $1,070,000, resulting in a gain of $732,000. In November 1995, Trex
    Medical issued 1,862,000 shares of its common stock in a private

    12.  Costs Associated with Divisional Restructuring

         Costs associated with divisional restructuring in the accompanying
    fiscal 1995 and 1994 statement of income result from the decision to
    close the Company's division located in Waltham, Massachusetts. The
    fiscal 1995 restructuring costs primarily represent the write-off of cost
    in excess of net assets of acquired companies and disposal of equipment.
    The 1994 costs primarily represent severance costs for approximately 34
    employees at this location and, to a lesser extent, the cost to write off
    leasehold improvements.

    To the Shareholders and Board of Directors of ThermoTrex Corporation:

         We have audited the accompanying consolidated balance sheet of
    ThermoTrex Corporation (a Delaware corporation and 51%-owned subsidiary
    of Thermo Electron Corporation) and subsidiaries as of September 28, 1996
    and September 30, 1995, and the related consolidated statements of
    income, shareholders' investment, and cash flows for the year ended
    September 28, 1996, the nine months ended September 30, 1995, and the
    year ended December 31, 1994. These consolidated financial statements are
    the responsibility of the Company's management. Our responsibility is to
    express an opinion on these consolidated financial statements based on
    our audits.

         We conducted our audits in accordance with generally accepted
    auditing standards. Those standards require that we plan and perform the
    audit to obtain reasonable assurance about whether the financial
    statements are free of material misstatement. An audit includes
    examining, on a test basis, evidence supporting the amounts and
    disclosures in the financial statements. An audit also includes assessing
    the accounting principles used and significant estimates made by
    management, as well as evaluating the overall financial statement
    presentation. We believe that our audits provide a reasonable basis for
    our opinion.

         In our opinion, the consolidated financial statements referred to
    above present fairly, in all material respects, the financial position of
    ThermoTrex Corporation and its subsidiaries as of September 28, 1996 and
    September 30, 1995, and the results of their operations and their cash
    flows for the year ended September 28, 1996, the nine months ended
    September 30, 1995, and the year ended December 31, 1994, in conformity
    with generally accepted accounting principles.

    Management's Discussion and Analysis of Financial Condition and Results
    of Operations

         Forward-looking statements, within the meaning of Section 21E of
    the Securities Exchange Act of 1934, are made throughout this
    Management's Discussion and Analysis of Financial Condition and Results
    of Operations. These statements involve a number of risks and
    uncertainties, including those detailed immediately after this
    Management's Discussion and Analysis of Financial Conditions and Results

    of Operations under the caption "Forward-looking Statements."

    Overview

         The Company operates in three business segments: Medical Products
    manufactured by the Company's 80%-owned Trex Medical Corporation (Trex
    Medical) subsidiary, Personal-care Products and Services offered by the
    Company's 64%-owned ThermoLase Corporation (ThermoLase) subsidiary, and
    Advanced Technology Research.

         Trex Medical designs, manufactures, and markets mammography
    equipment and minimally invasive stereotactic breast-biopsy systems,
    general radiography (X-ray) equipment, and X-ray imaging systems used for
    cardiac catheterization and angiography, as well as radiographic
    fluoroscopy. Trex Medical sells its systems worldwide principally through
    a network of independent dealers, and also acts as an original equipment
    manufacturer (OEM) for other medical equipment companies. Trex Medical
    has four operating units: Lorad, a manufacturer of mammography and
    stereotactic breast-biopsy systems; Bennett X-Ray Corporation (Bennett),
    a manufacturer of general X-ray and mammography equipment; XRE
    Corporation (XRE), a manufacturer of X-ray imaging systems used in the
    diagnosis and treatment of coronary artery disease and other vascular
    conditions; and Continental X-Ray Corporation (Continental), a
    manufacturer of general-purpose and specialized X-ray systems.

         ThermoLase has developed a laser-based system called SoftLight(SM)
    for the removal of unwanted hair. The SoftLight system uses a low-energy,
    dermatology laser in combination with a lotion that absorbs the laser's
    energy to disable hair follicles. In April 1995, the Company received
    clearance from the U.S. Food and Drug Administration (FDA) to
    commercially market services using the SoftLight system. The Company
    began earning revenue from the SoftLight system in the first quarter of
    fiscal 1996 as a result of opening its first commercial salon (Spa Thira)
    in La Jolla, California, in November 1995. ThermoLase opened additional
    salons in Dallas in June 1996, in Houston and Beverly Hills in September
    1996, in Denver in October 1996, and in Boca Raton in November 1996.
    ThermoLase also plans to open a salon in suburban Detroit in December
    1996 and has signed leases for four additional sites in Greenwich,
    Connecticut; Manhasset, New York; suburban Minneapolis; and Palm Beach,
    Florida. In June 1996, ThermoLase commenced a program to license to
    doctors the right to perform the Company's patented SoftLight hair-
                                       31PAGE

    Overview (continued)

    removal procedure. In this program, ThermoLase licenses its technology to
    physicians and receives a per-procedure royalty that varies depending on
    the location treated. ThermoLase also provides the doctors with the
    lasers and supplies that are necessary to perform the service. ThermoLase
    is marketing the SoftLight system internationally through joint ventures
    and other licensing arrangements, including separate joint ventures
    established in Japan in January 1996 and in France in November 1996, and
    a licensing arrangement established in Saudi Arabia in November 1996.
    ThermoLase also manufactures and markets skin-care, bath, and body
    products through its CBI Laboratories, Inc. (CBI) subsidiary, which
    manufactures the lotion used in the SoftLight hair-removal process.

         The Company's Advanced Technology Research segment performs
    research primarily in the fields of communications, avionics, X-ray
    detection, signal processing, advanced-materials technology, and lasers.
    The Company has developed its expertise in these core technologies in
    connection with government-sponsored research and development.

    Results of Operations

         In September 1995, the Company changed its fiscal year end from the
    Saturday nearest December 31 to the Saturday nearest September 30.
    Accordingly, the results of operations for 1996 compares the year ended
    September 28, 1996 (fiscal 1996) with the unaudited year ended September
    30, 1995 (1995). The results of operations for 1995 compares the nine
    months ended September 30, 1995 (fiscal 1995) with the unaudited nine
    months ended October 1, 1994 (fiscal 1994).

    Fiscal 1996 Compared With 1995

         Total revenues increased 63% to $182.0 million in fiscal 1996 from
    $111.6 million in 1995. Medical Products segment revenues, excluding
    intersegment sales, increased 102% to $141.8 million in fiscal 1996,
    compared with $70.2 million in 1995. Medical Products segment revenues
    increased $56.2 million due to the acquisitions of Bennett, XRE, and
    Continental. In addition, revenues at Lorad, excluding intersegment
    sales, increased 24% as a result of increased demand for mammography,
    biopsy, and nondestructive testing (NDT) systems. Personal-care Products
    and Services segment revenues increased 19% to $27.8 million in fiscal
    1996 from $23.3 million in 1995, primarily due to the inclusion of $2.6
    million in revenues from ThermoLase's Spa Thira salons and doctors'
    licensing program, as well as $2.0 million in SoftLight licensing fees
    from the joint venture established in Japan in January 1996. Revenues at
    CBI were $23.2 million in fiscal 1996, compared with $23.3 million in
    1995. ThermoLase estimates that CBI will continue to represent a smaller
    portion of its total revenues as revenues from hair-removal services
    increase. During fiscal 1996, ThermoLase opened its first four Spa Thira
    salons, including two that opened in September 1996. Under the current
    pricing structure, the majority of spa clients pay a fixed fee in advance
    to receive a series of treatments, as necessary. Consequently, ThermoLase
                                       32PAGE
<PAGE>
    ThermoTrex Corporation

    Fiscal 1996 Compared With 1995 (continued)

    defers revenue related to such payments, which is recognized over the
    anticipated treatment period. As ThermoLase collects further data
    concerning the number of treatments required and duration of the
    treatment period, the period of revenue recognition may be affected.

         In January 1996, ThermoLase entered into a joint venture agreement
    to market its SoftLight system in Japan as well as its laser-based
    skin-rejuvenation process, if and when available. ThermoLase currently
    holds a 50% stake in the joint venture with an option to increase its
    ownership to 51% pursuant to a fair-value purchase option. The agreement
    calls for ThermoLase to receive minimum guaranteed payments of $1,000,000
    in fiscal 1997, subject to certain exceptions in the event the joint
    venture is unable to obtain patent protection in Japan on prescribed
    terms.

         Advanced Technology Research segment revenues, excluding
    intersegment sales, declined to $12.4 million in fiscal 1996, from $18.1
    million in 1995, primarily due to lower funding levels for the Company's
    government-sponsored research and development contracts and the sale of
    the Company's thermoelectrics and thermionics businesses. The Company
    estimates that revenues from Advanced Technology Research will continue
    to decline as a percentage of total revenues.

         The gross profit margin declined to 38% in fiscal 1996, compared
    with 41% in 1995. The Medical Products segment gross profit margin,
    excluding intersegment sales, declined to 42% in fiscal 1996 from 49% in
    1995, primarily due to the inclusion of lower-margin revenues at Bennett
    and XRE. The Personal-care Products and Services segment gross profit
    margin was 28% in fiscal 1996, compared with 37% in 1995. The decline was
    primarily due to the early operations of the Spa Thira business, which
    has been operating below maximum capacity as ThermoLase develops a client
    base, continues refining its operating procedures, and incurs pre-opening
    costs, offset in part by the effect of revenues from the joint venture in
    Japan and doctors' licensing program. As ThermoLase opens additional Spa
    Thira locations in fiscal 1997, the effect of operating each spa below
    maximum capacity as ThermoLase develops its client base, as well as
    pre-opening costs, will have a negative impact on the gross profit
    margin. In addition, the decline in the gross profit margin in fiscal
    1996 resulted from lower margins on the sale of skin-care and other
    personal-care products at CBI due to a shift to lower-margin products.
    The Advanced Technology Research segment gross profit margin decreased to
    17% in fiscal 1996 from 19% in 1995, primarily due to cost overruns on
    certain contracts, offset in part by the absence of certain lower-margin
    contracts as a result of the closure of the Company's division in
    Waltham, Massachusetts, in 1995 (Note 12).

    Fiscal 1996 Compared With 1995 (continued)

         Selling, general and administrative expenses as a percentage of
    revenues declined to 23% in fiscal 1996 from 24% in 1995, primarily due
    to increased revenues at Lorad and the inclusion of the operations of
    Bennett and XRE, which incurred lower expenses as a percentage of
    revenues. This decrease was offset in part by an increase in selling,
    general and administrative expenses as a percentage of revenues for the
    Advanced Technology Research segment primarily due to its decrease in
    revenues.

         Research and development expenses increased to $25.0 million in
    fiscal 1996 from $18.0 million in 1995, due to the inclusion of $4.2
    million of expense at Bennett and XRE, and continued efforts to develop
    and commercialize new products including the M-IV mammography system
    (first shipped in the fourth quarter of fiscal 1996), the full-breast
    digital mammography system, and the direct-detection X-ray sensor, as
    well as enhancements of existing systems.

         In 1995 the Company recorded restructuring expenses of $1.0 million
    resulting from the decision to close its division located in Waltham,
    Massachusetts (Note 12). During fiscal 1996 and 1995, this division
    recorded revenues of $0.4 million and $3.0 million, respectively, and
    incurred operating losses of $0.1 million and $0.7 million, respectively.

         Interest income increased to $6.0 million in fiscal 1996 from $4.2
    million in 1995, primarily as a result of interest income earned on
    invested proceeds from ThermoLase's August 1995 public offering of common
    stock and Trex Medical's private placements of common stock in November
    1995 and January 1996 and its initial public offering in July 1996.
    Interest expense in fiscal 1996 and 1995 primarily represents interest
    associated with an $8.0 million promissory note issued to Thermo Electron
    in September 1995. This note was repaid in September 1996, and the
    Company issued a $2.0 million promissory note to Thermo Electron on
    similar terms.

         The Company has adopted a strategy of spinning out certain of its
    businesses into separate subsidiaries and having these subsidiaries sell
    a minority interest to outside investors. The Company believes that this
    strategy provides additional motivation and incentives for the management
    of the subsidiary through the establishment of subsidiary-level stock
    option incentive programs, as well as capital to support the
    subsidiaries' growth. As a result of the sale of stock by Trex Medical in
    fiscal 1996 and ThermoLase in 1995, the Company recorded gains of $39.1
    million and $34.7 million in fiscal 1996 and 1995, respectively (Note
    11). These gains represent an increase in the Company's proportionate
    share of the subsidiary's equity and are classified as "gain on issuance
    of stock by subsidiaries" in the accompanying statement of income. The
    size and timing of these transactions are dependent on market and other
    conditions that are beyond the Company's control. Also, the accounting
    rules applicable to these transactions may change. See "Risks Associated

    with Spinout of Subsidiaries" under the heading "Forward-looking
    Statements" below. Accordingly, there can be no assurance that the
    Company will be able to realize gains from such transactions in the
    future.

         Minority interest expense in fiscal 1996 represents minority
    shareholders' allocable share of Trex Medical's net income, offset in
    part by minority shareholders' allocable share of ThermoLase's net loss.
    Minority interest income in 1995 represents minority shareholders'
    allocable share of ThermoLase's net loss.

         The effective tax rates in fiscal 1996 and 1995 differ from the
    statutory federal income tax rate due to the nontaxable gains on issuance
    of stock by subsidiaries, offset in part by nondeductible amortization of
    cost in excess of net assets of acquired companies and the impact of
    state income taxes.

         The Company is a defendant in certain patent litigation and has
    been notified that it allegedly infringes certain other technologies
    owned by third parties (Notes 4 and 10). While an unfavorable outcome of
    one or more of these matters could have a material adverse effect on the
    Company's results of operations, the Company does not believe that it is
    reasonably likely that any resolution would have a material effect on the
    Company's financial position.

    Fiscal 1995 Compared With Fiscal 1994

         Total revenues increased 31% to $86.5 million in fiscal 1995 from
    $66.0 million in fiscal 1994. Medical Products segment revenues,
    excluding intersegment sales, increased 40% to $55.0 million in fiscal
    1995, compared with $39.2 million in fiscal 1994.  The increase resulted
    from higher demand across all product lines, with significant growth
    coming from export sales, which accounted for 21% of Medical Products
    segment revenues in fiscal 1995, compared with 11% in fiscal 1994.
    Personal-care Products and services segment revenues increased 36% to
    $17.5 million in fiscal 1995 from $12.9 million in fiscal 1994 due to an
    increase in demand at CBI.

         Advanced Technology Research segment revenues, excluding
    intersegment sales, were $14.0 million in fiscal 1995, compared with
    $13.9 million in fiscal 1994, as funding levels for the Company's
    government-sponsored research and development contracts remained
    relatively unchanged.

         The gross profit margin declined to 41% in fiscal 1995 from 42% in
    fiscal 1994. The Medical Products segment gross profit margin, excluding
    intersegment sales, declined to 48% in fiscal 1995, compared with 50% in
    fiscal 1994, primarily due to a nonrecurring adjustment to expense of
    $0.3 million for inventory revalued at the time of Bennett's acquisition
    by the Company. The Personal-care Products and Services segment gross
    profit margin was 35% in fiscal 1995, compared with 42% in fiscal 1994,

    Fiscal 1995 Compared With Fiscal 1994 (continued)

    due to lower margins at CBI as a result of an increase in the price of
    raw materials and, to a lesser extent, a shift in product mix. The gross
    profit margin for Advanced Technology Research segment decreased to 16%
    in fiscal 1995 from 17% in fiscal 1994, due to overhead incurred in
    excess of amounts billable on government-sponsored contracts.

         Selling, general and administrative expenses as a percentage of
    revenues declined to 24% in fiscal 1995 from 27% in fiscal 1994. The
    decline was due to increased revenues at Trex Medical, partially offset
    by an increase in expense at ThermoLase resulting from increased selling
    efforts to expand the market for ThermoLase's skin-care and other
    personal-care products and the buildup of the infrastructure necessary
    for the operation of a personal-care service network.

         Research and development expenses increased to $13.4 million in
    fiscal 1995 from $9.6 million in fiscal 1994, reflecting ThermoLase's
    expanded efforts to develop and commercialize the SoftLight system and,
    to a lesser extent, continued efforts to develop the full-breast digital
    mammography system, the Sonic CT(TM) medical imaging device, and the
    passive microwave camera synthetic vision system.

         In fiscal 1995 and fiscal 1994, the Company recorded restructuring
    expenses of $1.0 million and $0.7 million, respectively, resulting from
    the decision to close its division located in Waltham, Massachusetts
    (Note 12). During fiscal 1995 and fiscal 1994, this division recorded
    revenues of $2.4 million and $2.0 million, respectively, and incurred
    operating losses of $0.6 million and $0.8 million, respectively.

         Interest income increased to $3.2 million in fiscal 1995 from $2.3
    million in fiscal 1994, primarily as a result of interest income earned
    on invested proceeds from the Company's March 1994 public offering of
    common stock, ThermoLase's July 1994 initial public offering of common
    stock and, to a lesser extent, the June and August 1995 offerings of
    ThermoLase common stock. This increase was offset slightly by lower
    invested amounts due to the cash expended to acquire Bennett. Interest
    expense in fiscal 1995 represents interest associated with the $8.0
    million promissory note issued to Thermo Electron in September 1995.
    Interest expense in fiscal 1994 represents interest associated with notes
    payable of $6.7 million that were repaid in January 1994.

         As a result of the sale of stock by ThermoLase, the Company
    recorded gains of $34.7 million and $8.6 million in fiscal 1995 and
    fiscal 1994, respectively.

         Minority interest income in fiscal 1995 represents minority
    shareholders' allocable share of ThermoLase's net loss.

         The effective tax rates in fiscal 1995 and fiscal 1994 differ from
    the statutory federal income tax rate due to the nontaxable gain on
    issuance of stock by subsidiary, offset in part by nondeductible
    amortization of cost in excess of net assets of acquired companies and
    the impact of state income taxes.

    Liquidity and Capital Resources

         Consolidated working capital was $127.9 million at September 28,
    1996, compared with $103.3 million at September 30, 1995. Included in
    working capital are cash, cash equivalents, and available-for-sale
    investments of $95.6 million at September 28, 1996, compared with $87.1
    million at September 30, 1995. Of the $95.6 million balance at September
    28, 1996, $52.1 million was held by ThermoLase, $34.0 million was held by
    Trex Medical, and the remainder was held by the Company and its wholly
    owned subsidiary. Net cash provided by operating activities during fiscal
    1996 was $4.9 million.

         The Company's investing activities used cash of $41.9 million in
    fiscal 1996. In May 1996, Trex Medical acquired XRE for approximately
    $18.5 million in cash, net of cash acquired and including the repayment
    of debt. In September 1996, Trex Medical acquired Continental for
    approximately $18.4 million in cash, net of cash acquired and including
    the repayment of debt. In addition, the Company expended $14.5 million
    for property, plant and equipment during fiscal 1996.

         The Company's financing activities provided cash of $59.4 million
    in fiscal 1996. The Company raised $71.9 million from the sale of Company
    and subsidiary common stock and repaid an $8.0 million promissory note
    from Thermo Electron.

         In September 1996, ThermoLase's Board of Directors authorized the
    repurchase by ThermoLase of up to $10.0 million of its common stock
    through August 28, 1997, in market transactions or pursuant to the
    exercise by investors of standardized put options written on ThermoLase
    common stock. As of December 1, 1996, no shares had been repurchased,
    however, ThermoLase had contingent obligations under outstanding put
    options to purchase up to 80,000 shares for $1.5 million.

         In addition to the Denver, Boca Raton, and suburban Detroit spas
    which were being completed as of September 28, 1996, ThermoLase has
    signed leases in Greenwich, Connecticut; Manhasset, New York; suburban
    Minneapolis; and Palm Beach, Florida where it plans to open additional
    Spa Thira salons. ThermoLase plans to open between 10 and 20 additional
    spas in various parts of the United States during fiscal 1997. Depending
    on the size of the salon, each facility will require approximately $1.5
    million to $2.5 million for such items as leasehold improvements and
    laser systems. In addition, ThermoLase expects to expend between $8.0
    million and $10.0 million during fiscal 1997 for equipment related to its
    program to license doctors the right to perform hair-removal services. In
    addition to capital expenditures planned by ThermoLase, the Company plans
    to expend approximately $5.0 million on other capital additions in fiscal
    1997.

         The Company believes it has adequate resources to meet its
    financial needs for the foreseeable future.

    Forward-looking Statements

         In connection with the "safe harbor" provisions of the Private
    Securities Litigation Reform Act of 1995, the Company wishes to caution
    readers that the following important factors, among others, in some cases
    have affected, and in the future could affect, the Company's actual
    results and could cause its actual results in fiscal 1997 and beyond to
    differ materially from those expressed in any forward-looking statements
    made by, or on behalf of, the Company. 

         No Assurance of Development  and Commercialization of Products Under
    Development.    The Company has  several lines  of existing products  and
    number of  commercial  products under  development.  Product  development
    involves a high degree  of risk, and returns  to investors are  dependent
    upon  successful  development  and  commercialization  of  the  Company's
    proposed products. Proposed products based on the Company's  technologies
    will require  significant  research  and development.  There  can  be  no
    assurance  that  any   products  developed   by  the   Company  will   be
    commercialized or that  development will be  completed in any  particular
    time frame. In addition, there can be no assurance that the Company  will
    be able to build manufacturing, marketing, and distribution organizations
    that will  be  necessary  for the  successful  commercialization  of  its
    commercial products under development.

         The Company has developed several of its core technologies in
    connection with government-sponsored research and development. The
    Company is seeking government funding for further applications of certain
    of its core technologies, but there can be no assurance that such funding
    can be obtained on favorable terms, if at all. In addition, the Company
    does not expect that government funding will be sufficient to complete
    the development of the Company's proposed commercial products. In order
    to further or complete the development of its commercial products, the
    Company may seek to raise additional funds for specific projects or for
    subsidiaries of the Company that will commercialize its products. There
    can be no assurance that funding for further development of the Company's
    commercial products can be obtained on favorable terms, if at all. Such
    funding may include funding from capital markets.

         Uncertain Market Acceptance. The success of the Company's products
    depends on obtaining favorable perceptions of the Company's products by
    markets and opinion leaders. ThermoLase's SoftLight process for laser
    hair removal is significantly different from current commercially
    available hair-removal technologies. With any new cosmetic technology,
    there is substantial risk that the marketplace may not accept or be
    receptive to the potential benefits of such technology. Market acceptance
    of the SoftLight process will depend, in large part, upon the ability of
    ThermoLase to demonstrate to consumers the safety and effectiveness of
    the SoftLight process and its advantages over other types of hair-removal
    treatment. There can be no assurance that the SoftLight process will be
    accepted by the general public. The Company's passive microwave camera
    and laser communication technology, ThermoLase's skin-rejuvenation
    system, and Trex Medical's full-breast digital imaging system are also
    significantly different from current technologies and, if successfully
    developed, will be subject to similar market acceptance risks.

    Forward-looking Statements (continued)

         Government Regulation; No Assurance of Regulatory Approvals.
    Certain of the Company's products are subject to pre-marketing clearance
    or approval by the U.S. Food and Drug Administration (FDA) and similar
    agencies in foreign countries. The use or sale of certain of the
    Company's commercial products under development will require approvals by
    other government agencies, such as the Federal Aviation Administration.
    Trex Medical's full-breast digital imaging system and ThermoLase's
    skin-rejuvenation system require the completion of human clinical trials
    prior to submissions for FDA approval. Clinical trials of the digital
    imaging system and the skin-rejuvenation system are currently under way.
    At the conclusion of the trials, the Company expects its subsidiaries to
    submit 510(k) applications for FDA approval, but there can be no
    assurance that there will be favorable clinical results, which are
    necessary for such submissions. The process of obtaining FDA approvals is
    time consuming and expensive. There can be no assurance that the FDA will
    accept any of such 510(k) applications, and may require additional data
    or alternative and more time-consuming approval procedures. Furthermore,
    there can be no assurance that the necessary approvals for any of the
    products will be obtained on a timely basis, or at all.

         FDA regulations also require continuing compliance with specific
    standards in conjunction with the maintenance and marketing of products
    and services that have been approved. If such regulations are not
    complied with on an ongoing basis, the FDA can enjoin production, seize
    products, and levy fines.

         The Company recognizes for purposes of commercializing the
    ThermoLase centers that the operation of the SoftLight process may be
    deemed by certain regulators to constitute the practice of medicine. If
    operation of the SoftLight process is determined to involve the practice
    of medicine, the degree of physician involvement required in delivering
    the process is unclear. In addition, many states prohibit business
    corporations from engaging in the practice of medicine, employing
    physicians, or entering into certain financial arrangements with
    physicians, including fee splitting. Although the Company believes that
    the existing and proposed structures for the ThermoLase centers and its
    relationships with physicians and others comply with applicable laws and
    regulations, no formal ruling regarding such structures and relationships
    has been obtained from any government agency and there can be no
    assurance that any such ruling would deem such structures or
    relationships in compliance with applicable laws and regulations.  There
    can be no assurance that review of the Company's business by courts or
    healthcare, tax, labor, and other regulatory authorities that have
    jurisdiction over matters including, without limitation, the corporate
    practice of medicine, licensure of facilities, practitioners and
    equipment and franchising will not result in determinations that could
    adversely affect the operations of the Company or that the healthcare
    regulatory environment will not change in a manner that would restrict
    the Company's proposed operations or limit the expansion of the Company's
    business or otherwise adversely affect the Company.

    Forward-looking Statements (continued)

         Healthcare Reform; Uncertainty of Patient Reimbursement. The
    federal government has in the past and may in the future consider, and
    certain state and local as well as a number of foreign governments are
    considering or have adopted, healthcare policies intended to curb rising
    healthcare costs. Such policies include rationing of government-funded
    reimbursement for healthcare services and imposing price controls upon
    providers of medical products and services. The Company cannot predict
    what healthcare reform legislation or regulation, if any, will be enacted
    in the United States or elsewhere. Significant changes in the healthcare
    systems in the United States or elsewhere are likely to have a
    significant impact over time on the manner in which Trex Medical conducts
    its business. In addition, the federal government regulates reimbursement
    of fees for certain diagnostic examinations and capital equipment
    acquisition costs connected with services to Medicare beneficiaries.
    Recent legislation has limited Medicare reimbursement for diagnostic
    examinations. These policies may have the effect of limiting the
    availability or reimbursement for certain procedures, and as a result may
    inhibit or reduce demand by healthcare providers for products in the
    markets in which Trex Medical competes. While the Company cannot predict
    what effect the policies of government entities and other third-party
    payors will have on future sales of Trex Medical's products, there can be
    no assurance that such policies would not have an adverse impact on the
    operations of the Company.

         Technological Developments and Intense Competition. The Company's
    products do, and will, compete in fields characterized by rapid
    technological progress and intense competition. New developments in
    technology may have a material adverse effect on the development or sale
    of some or all of the Company's products or render such products
    noncompetitive or obsolete. Other companies, many of which have
    substantially greater capital resources, marketing experience, research
    and development staffs and facilities than the Company, are currently
    engaged in the sale and development of products and technologies that are
    similar to, and may be competitive with, certain of the Company's
    products and technologies. There can be no assurance that the Company's
    current products, products under development, or ability to discover new
    technologies will be sufficient to enable it to compete effectively with
    its competitors.

         In 1994, the Company conducted a clinical trial using a SoftLight
    laser to collect data on the effectiveness of the SoftLight hair-removal
    process under the clinical protocol established for the Company's FDA
    submission. Results were based on a dermatologist's visual observation of
    each subject's treatment area at various time intervals after treatment
    and varied depending upon the anatomical site treated. Of the 65
    anatomical sites screened 12 weeks after receiving such treatment, 49
    (75%) experienced a reduction in hair growth greater than 30%, with the
    average reduction in hair growth equal to 46%. Of the 32 anatomical sites
    screened 24 weeks after receiving such treatment, 21 (66%) experienced a
    reduction in hair growth greater than 30%, with the average reduction in
    hair growth equal to 39%. Although ThermoLase received FDA clearance in
    April 1995 to commercially market the SoftLight process, ThermoLase
    continues to study the process to better understand the effects of the
                                       40PAGE

    Forward-looking Statements (continued)

    system and to develop the system in order to increase its effectiveness
    and the length of time in between treatments. These studies will also be
    used to further clarify the duration for which hair will be removed, the
    number of treatments required to effectively remove hair from a given
    area, and the effectiveness of the process across a broad range of skin
    types and anatomical sites. In addition, although ThermoLase has not
    observed any significant side effects to date, it is continuing to
    monitor subjects and customers for the development of possible side
    effects. Failure to further improve the SoftLight process may limit
    ThermoLase's ability to successfully commercialize the SoftLight process.

         Need to Manage Growth; Ability to Attract Qualified Personnel.
    ThermoLase is experiencing a period of rapid growth as it commences
    commercial operations of its SoftLight process. ThermoLase presently
    intends to commercialize the SoftLight process in the United States
    primarily through affiliated spas and a network of physicians using the
    process as part of their practices. ThermoLase will be required to
    recruit and train a large number of personnel for its spas, including
    medical staff such as physicians, registered nurses, physician
    assistants, or other personnel. There may be only a limited number of
    such persons with the requisite skills, and it may become increasingly
    difficult for ThermoLase to hire such personnel over time. ThermoLase
    will also be required to recruit qualified physicians for its network of
    physician practices that offer the SoftLight process. Such qualified
    physicians may not be available or interested in offering the SoftLight
    process in their private practices. ThermoLase's commercialization
    strategy may also significantly strain operational, management,
    financial, sales and marketing, and other resources. To manage growth
    effectively, ThermoLase must continue to enhance its systems and controls
    and successfully expand, train, and manage its employee base and
    physician network. There can be no assurance that ThermoLase will be able
    to manage this expansion effectively. 

         Intellectual Property Rights, Uncertainties and Litigation. The
    Company places considerable importance on obtaining patent and trade
    secret protection for significant new technologies, products and
    processes because of the length of time and expense associated with
    bringing new products through development and the regulatory approval
    process to the marketplace. Proprietary rights relating to the Company's
    products will be protected from unauthorized use by third parties only to
    the extent that they are covered by enforceable patents or are maintained
    in confidence as trade secrets. Certain technology that may be used in
    the Company's products is not covered by any patent or patent application
    and therefore may be the subject of ownership disputes. The Company
    generally relies on trade secrecy agreements to protect such technology,
    but there can be no assurance that such agreements will provide
    meaningful protection or that others will not independently develop
    substantially equivalent technology. There can be no assurance that
    patent applications covering the Company's products will be successfully
    filed or that patents will ultimately issue. Further, even if patents are
    issued, the protection afforded by such patents and the Company's
    existing patents will depend upon their scope and validity. In addition,
    there can be no assurance that the Company's patents will not be
                                       41PAGE

    challenged. There may be patents or other intellectual property rights
    owned by others, which if infringed by the Company would permit the owner
    to prevent the Company from making, selling, or using the affected
    product or process without a license and to be entitled to damages for
    past infringement. ThermoLase has from time to time received allegations
    that the SoftLight process infringes the intellectual property rights of
    others and may continue to receive such allegations in the future.
    Protection and defense of intellectual property rights may involve the
    commitment of large amounts of time and financial resources. Furthermore,
    the government retains a non-exclusive, royalty-free license to use
    technology developed under government contracts for government purposes.
    If the Company decides not to pursue further development of
    government-sponsored technology, the government could, in certain
    circumstances, transfer that technology to a third party.

         Fischer Imaging Corporation (Fischer) sued Trex Medical's Lorad
    division in April 1992, alleging that Lorad's prone breast-biopsy systems
    infringe a Fischer patent on a precision mammographic needle-biopsy
    system. As of September 28, 1996, Trex Medical had revenues of
    approximately $63.1 million from the sale of such systems. The suit
    requests a permanent injunction, treble damages, and attorney's fees and
    expenses. The Company also is aware of a U.S. patent held by a third
    party which has been asserted by him against certain automatic
    exposure-control features included in most of Trex Medical's current
    mammography systems. As of September 28, 1996, Trex Medical had accrued a
    reserve of approximately $2 million in connection with these matters,
    although given the inherent uncertainty of patent litigation and
    disputes, no assurance can be given as to the amount which the Company
    may eventually be required to pay in expenses, or in damages, if the
    Company is unsuccessful in defending these matters. The Company also has
    been notified that it allegedly infringes certain other technologies
    owned by third parties.

         Potential Product Liability. The administration of medical
    treatments is subject to various risks of physical injury to the patient.
    The Company maintains product liability insurance, but there is no
    assurance that this insurance will provide sufficient coverage in the
    event of a claim. Furthermore, there can be no assurance that the Company
    will be able to maintain its insurance coverage or that insurance
    coverage will continue to be available at economically feasible rates.

         Dependence Upon Significant OEM Relationships. A significant
    portion of Trex Medical's sales are through OEM arrangements with United
    States Surgical Corporation, General Electric Company, Inc., and the
    Philips Medical Systems North America Company subsidiary of Philips N.V.
    Trex Medical's sales depend, in part, on the continuation of these OEM
    arrangements and the level of end-user sales by such OEMs. There can be
    no assurance that Trex Medical will be able to maintain its existing, or
    establish new, OEM relationships.

    Forward-looking Statements (continued)

         Risks Associated with Acquisition Strategy. The Company's strategy
    includes the acquisition of businesses that complement or augment the
    Company's existing products and services. Promising acquisitions are
    difficult to identify and complete for a number of reasons, including
    competition among prospective buyers and the need for regulatory
    approvals, including antitrust approvals. Any acquisitions completed by
    the Company may be made at substantial premiums over the fair value of
    the net assets of the acquired companies. There can be no assurance that
    the Company will be able to complete future acquisitions or that the
    Company will be able to successfully integrate any acquired businesses.
    In order to finance such acquisitions, it may be necessary for the
    Company to raise additional funds through public or private financings.
    Any equity or debt financing, if available at all, may be on terms which
    are not favorable to the Company and, in the case of equity financing,
    may result in dilution to the Company's stockholders.

         Risks Associated with Spinout of Subsidiaries. The Company has
    adopted a strategy of spinning out certain of its businesses into
    separate subsidiaries and having these subsidiaries sell a minority
    interest to outside investors. As a result of the sale of stock by
    subsidiaries and similar transactions, the Company records gains that
    represent the increase in the Company's net investment in the
    subsidiaries. These gains have represented a substantial portion of the
    net income reported by the Company in certain periods. The size and
    timing of these transactions are dependent on market and other conditions
    that are beyond the Company's control. Accordingly, there can be no
    assurance that the Company will be able to generate gains from such
    transactions in the future.

         In addition, in October 1995, the Financial Accounting Standards
    Board (FASB) issued an exposure draft of a Proposed Statement of
    Financial Accounting Standards, "Consolidated Financial Statements:
    Policy and Procedures" (Proposed Statement). The Proposed Statement would
    establish new rules for how consolidated financial statements should be
    prepared. If the Proposed Statement is adopted, there could be
    significant changes in the way the Company records certain transactions
    of its controlled subsidiaries. Among those changes, any sale of the
    stock of a subsidiary that does not result in a loss of control would be
    accounted for as a transaction in equity of the consolidated entity with
    no gain or loss being recorded. The FASB expects to issue a final
    statement or a revised exposure draft in calendar 1997.
