                                     PART I

    Item 1. Business

    (a) General Development of Business

        Trex Medical Corporation (the Company or the Registrant) designs,
    manufactures, and markets mammography equipment and minimally invasive
    digital breast-biopsy systems used for the detection of breast cancer, as
    well as general-purpose X-ray equipment. In addition, the Company
    manufactures specialized X-ray equipment, including imaging systems used
    during diagnostic and interventional vascular and cardiac procedures such
    as balloon angioplasty, and radiographic/fluoroscopic (R/F) systems used
    to diagnose gastrointestinal (GI) disorders and other conditions.

        The Company, incorporated in September 1995 as a subsidiary of
    ThermoTrex Corporation (ThermoTrex), consists of four operating units:
    Lorad, Bennett X-Ray Corporation (Bennett), XRE Corporation (XRE), and
    Continental X-Ray Corporation (Continental). Through its Lorad division,
    the Company manufactures and markets mammography and minimally invasive
    digital breast-biopsy systems, which provide a cost-effective,
    less-invasive alternative to open surgery for the biopsy of suspicious
    breast lesions. Bennett's primary product line consists of
    general-purpose X-ray equipment, but Bennett also manufactures
    mammography systems, a digital 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. In October
    1997, XRE acquired substantially all of the assets, subject to certain
    liabilities, of Digitec Corporation, a manufacturer of
    physiological-monitoring equipment and digital-image archiving and
    networking systems used in cardiac catheterization procedures.
    Continental manufactures and markets a broad line of high-end
    general-purpose X-ray systems, as well as specialized units, including
    R/F systems used to diagnose GI disorders. In addition, Continental
    manufactures electrophysiology products that aid doctors in diagnosing
    and treating cardiac arrhythmia.

        The Company also manufactures the specialized hair-removal lasers
    purchased by its sister company, ThermoLase Corporation, another
    majority-owned subsidiary of ThermoTrex, and nondestructive testing
    systems, which are used by the military to test aircraft for stress
    fractures and other defects.

        The Company is currently developing a full-field digital mammography
    system that is intended to be capable of higher image quality. The system
    is designed to enhance the X-ray image through software and to allow
    near-real-time analysis. The Company expects that it will be possible to
    electronically transmit these images to allow off-site analysis by
    another radiologist. The Company believes this technology may also
    provide better images of dense breast tissue, which is often found in
    younger women. The Company has collected clinical data that was submitted
    in December 1997 with the Company's 510(k) application to the U.S. Food
    and Drug Administration (FDA), which must grant market clearance before
    this system can be sold commercially. The Company has designed its new,

                                        2PAGE
<PAGE>
    high-end conventional mammography systems so that radiologists can
    upgrade to digital technology when it becomes available. The Company
    believes that the digital-imaging technology being developed for this
    system may be adaptable to its general-purpose and specialized X-ray
    systems, and the Company will seek to develop applications in these
    markets. The Company is also working on a more advanced version of its
    digital technology, which incorporates a flat-panel, direct-digital
    detector and could provide still more information for earlier diagnoses.

        As of September 27, 1997, ThermoTrex, a publicly traded subsidiary of
    Thermo Electron Corporation (Thermo Electron), owned 22,883,798 shares of
    the common stock of the Company, representing 79% of such stock
    outstanding. In addition to the Company's products, ThermoTrex supplies
    laser-based hair-removal services and personal-care products through its
    ThermoLase subsidiary. Thermo Trex also conducts advanced technology
    research in the areas of communications, avionics, X-ray detection, and
    lasers. Thermo Electron is a world leader in environmental-monitoring and
    analysis instruments, papermaking and recycling equipment, biomedical
    products such as heart-assist devices, biomass electric power generation,
    and other specialized products and technologies. Thermo Electron also
    provides a range of services related to environmental quality.

        ThermoTrex intends, for the foreseeable future, to maintain at least
    50% ownership of the Company. This may require ThermoTrex to purchase
    additional shares of the Company's common stock from time to time, as the
    number of the Company's outstanding shares increases. These or any other
    purchases may be made either in the open market or directly from the
    Company. See Notes 4 and 7 to Consolidated Financial Statements in the
    Registrant's Fiscal 1997 Annual Report to Shareholders for a description
    of outstanding stock options and convertible note.

    Forward-looking Statements

        Forward-looking statements, within the meaning of Section 21E of the
    Securities Exchange Act of 1934, are made throughout this Annual Report
    on Form 10-K. For this purpose, any statements contained herein that are
    not statements of historical fact may be deemed to be forward-looking
    statements. Without limiting the foregoing, the words "believes,"
    "anticipates," "plans," "expects," "seeks," "estimates," and similar
    expressions are intended to identify forward-looking statements. There
    are a number of important factors that could cause the results of the
    Company to differ materially from those indicated by such forward-looking
    statements, including those detailed under the heading "Forward-looking
    Statements" in the Registrant's Fiscal 1997 Annual Report to
    Shareholders, which statements are incorporated herein by reference.

    (b) Financial Information About Industry Segments

        The Company conducts its business in one industry segment.

                                        3PAGE

    (c) Description of Business

        (i) Principal Services and Products

    Breast Cancer Detection

        Mammography Systems. Through Lorad and Bennett, the Company designs,
    manufactures, and markets mammography systems that are generally
    differentiated on the basis of price and performance. The Company's
    high-end models are the Lorad M-IV and the Bennett Contour Plus. Many of
    the Lorad M-IV's features were developed in response to user demands,
    including the ability to be upgraded to accept the full-field
    digital-imaging technology being developed by the Company, when
    available. The Bennett Contour Plus is also upgradable for digital
    imaging and offers a patented tilt C-arm that permits the system to tilt
    toward or away from the patient to aid in imaging breast tissue. The
    Company also offers two lower-priced models and two mobile mammography
    systems.

        The Company has collected clinical data using its prototype
    full-field digital mammography system. In December 1997, the Company
    submitted data collected using its prototypes to the FDA, which must
    grant market clearance before the Company can commercially market its
    full-field digital-imaging system.

        The Company is currently developing a next-generation full-field
    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.

        The Company believes that demand in the market for mammography
    systems is driven primarily by technological innovation that results in
    better image quality. Although growth of the installed base has slowed,
    demand for new systems continues as older models are replaced with those
    offering technological innovations. In addition, the Company believes
    that the market outside the United States will grow as more countries
    adopt mammography quality standards similar to those adopted in the
    United States.

        Minimally Invasive Digital Breast-biopsy Systems. The Company offers
    a variety of minimally invasive digital breast-biopsy systems,
    manufactured by Lorad and Bennett, that provide an alternative to
    surgical biopsy. These digital breast-biopsy systems were introduced to
    address the disadvantages of open surgical biopsy and can be performed on
    an outpatient basis under local anesthetic. 

        The Company offers a dedicated prone table, the StereoGuide(R), for
    customers that perform a significant number of biopsy procedures. With
    the dedicated prone table, the patient lies down with her breast
    suspended through an aperture in the table. X-ray imaging equipment and a
    needle-gun attachment (not manufactured by the Company) are mounted below
    the table. Patients on the prone table are more comfortable, increasing
    the likelihood they will remain still during the procedure, and cannot

                                        4PAGE
<PAGE>
    see the needle being inserted in the breast, reducing the chance of
    fainting. The typical cost of a minimally invasive breast-biopsy
    procedure is approximately one-third that of an open surgical biopsy. The
    Company's StereoGuide system is the subject of a lawsuit alleging
    infringement of a Fischer Imaging Corporation (Fischer) patent. See
    "Item 3 - Legal Proceedings."

        Since October 1995, when the Lorad division signed a multiyear,
    exclusive agreement with United States Surgical Corporation (U.S.
    Surgical), the Company has manufactured a modified version of the
    StereoGuide that is compatible with U.S. Surgical's Advanced
    Breast-biopsy Instrument (ABBI (TM)), a disposable component. U.S.
    Surgical markets this product as the ABBI system, which consists of the
    Company's digital guidance system and a specialized table that has been
    modified to accept the ABBI device. See "Dependency on a Single
    Customer."

        The Company also offers upright, add-on systems that can be attached
    to most of its mammography systems. Add-on systems principally consist of
    a needle-gun attachment that fits onto the mammography system in place of
    the breast-compression paddle. These systems enhance the functionality of
    a mammography system and are beneficial to customers who have only
    periodic demand for minimally invasive needle-biopsy procedures.

        The Company believes that the minimally invasive digital
    breast-biopsy system market will grow as the procedure becomes more
    widely accepted by the medical community and as pressures to contain
    healthcare costs increase. 

    General-purpose Radiography

        The Company addresses the general-purpose X-ray market through its
    Bennett and Continental subsidiaries. Bennett designs, manufactures, and
    markets basic X-ray 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. Continental (and, to a lesser extent, Bennett) markets the more
    sophisticated and expensive X-ray systems typically used in hospitals and
    clinics. These include the two linear tomography systems marketed by the
    Company. The Company believes that for a number of applications its
    linear tomography systems may be a cost-effective alternative to computed
    tomography (CT) systems. In addition, Bennett manufactures and markets
    imaging systems designed specifically for chiropractors and
    veterinarians.

        The U.S. market for general-purpose X-ray systems is stable, and
    consists primarily of replacement sales as customers upgrade older
    equipment. The Company 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. The
    Company has recently expanded its international sales efforts. 

        The Company believes digital imaging will have significant
    application in the general-purpose and specialized X-ray markets and that

                                        5PAGE
<PAGE>
    the technology it develops for its full-field digital imaging system may
    be adaptable to these applications. In general-purpose X-ray
    applications, the Company believes digital imaging will produce better
    quality images and reduce operating costs by eliminating the need for
    film, processing equipment, and chemicals. In addition, digital imaging
    will permit the electronic storage of images on magnetic or optical
    media, as well as the transmission of images to multiple locations.
    Furthermore, 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

        The Company's XRE subsidiary designs, manufactures, and markets
    cardiac catheterization laboratories (also called cath labs) and
    positioners for cardiovascular imaging systems. XRE's imaging equipment
    is used in cath labs where angiography (the examination of blood vessels
    using X-rays following the injection of a radiopaque contrast medium) is
    performed by an interventional cardiologist. XRE systems are designed to
    provide real-time images of peripheral blood vessels and of the heart and
    coronary arteries for physicians performing diagnostic and interventional
    procedures, such as balloon angioplasty.

        In recent years, significant advances have been made in the treatment
    of atherosclerosis, which can lead to a narrowing of the arteries, and
    other coronary artery diseases without extensive surgery. A common
    alternative treatment to open-heart bypass surgery is balloon
    angioplasty, a procedure in which a segment of a narrowed coronary artery
    is stretched by the inflation of a balloon introduced into the affected
    artery. A more recent development involves the permanent implantation of
    a device called a stent into the blood vessel in order to keep the
    restricted vessel open once it has been expanded by balloon angioplasty.
    The Company believes vascular and cardiovascular surgeons will
    increasingly use balloon angioplasty and these other less-invasive
    techniques to treat vascular diseases. These procedures are performed
    under the guidance of X-ray imaging such as that provided by the
    Company's equipment.

        XRE's products include the Unicath C cardiovascular imaging system,
    the Unicath LP biplane cardiovascular imaging system, and the Unicath SP,
    its newest single-plane cardiovascular imaging system, with enhanced
    features such as a larger X-ray tube and advanced image intensifier with
    Full-Frame(TM) Zoom to further improve the visualization of
    interventional devices such as stents.

        To complement its Unicath SP labs, XRE has developed a line of
    digital image-processing systems, workstations, and archive alternatives.
    XRE's new DVFX digital video filter system acquires, enhances, and
    displays high-resolution images at 30 frames per second to clearly image
    and freeze the motion of the heart. In October 1997, XRE acquired
    substantially all of the assets, subject to certain liabilities, of
    Digitec Corporation, a North Carolina-based manufacturer of
    physiological-monitoring equipment and digital-image archiving and
    networking systems used in cardiac catheterization procedures. The

                                        6PAGE
<PAGE>
    digital-image management system integrates physiological data, acquired
    images, and other data to create a single source of patient information.

        In addition, the Company's Continental subsidiary designs,
    manufactures, and sells electrophysiology systems that are used in the
    diagnosis and treatment of cardiac arrhythmia, which is characterized by
    the sudden, erratic beating of the heart and can result in cardiac
    arrest.

    Radiographic/Fluoroscopic Systems

        Through its Continental subsidiary, the Company designs,
    manufactures, and markets radiographic/fluoroscopic (R/F) products. An
    R/F system is able to record dynamic events by capturing a series of
    images in a short period of time. For example, R/F systems are used for
    various gastrointestinal procedures to image in real-time the progress of
    a radiopaque ingested solution (typically barium) through the digestive
    tract.

        Continental produces R/F systems using advanced high-frequency
    generators that provide pulsed power, resulting in substantially reduced
    radiation exposure to the patient. Continental's R/F products include the
    DigiSpot (TM) 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 to film-based systems.

    Other Products

        The Company uses its technological and manufacturing expertise to
    produce a number of other products.

        The Company's LPX-160 portable imaging system, based on the Company's
    medical imaging technology, is designed to produce high-resolution images
    of metals, composites, and plastics. Customers for this system have
    included the United States Air Force, several commercial airlines, and
    Canadian and American utilities.

        The Company manufactures the lasers used in ThermoLase Corporation's
    hair-removal process. ThermoLase is a publicly traded, majority-owned
    subsidiary of ThermoTrex. During fiscal 1997*, 1996, and 1995, sales of
    these lasers totaled $11,390,000, $8,549,000, and $350,000, respectively.
    The Company has committed to deliver additional laser systems and
    components to ThermoLase under this arrangement for approximately
    $6.0 million.

    * In September 1995, the Company changed its fiscal year end from the
      Saturday nearest December 31 to the Saturday nearest September 30.
      References to fiscal 1997, fiscal 1996, and fiscal 1995 herein are for
      the years ended September 27, 1997, and September 28, 1996, and the
      nine months ended September 30, 1995, respectively. 

                                        7PAGE
<PAGE>
    Sales and Distribution

        The Company sells its products through a worldwide network of more
    than 100 independent dealers and, to a lesser extent, on a direct basis.
    Each of the Company's operating units employs regional sales managers who
    oversee the performance of the independent dealers on a domestic and
    international basis and, in certain instances, support direct sales
    efforts. The Company and its independent dealers maintain a staff of
    factory-trained service technicians to support its systems on a worldwide
    basis.

    OEM Agreements

        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 U.S. Surgical and the GE Medical
    Systems division of General Electric Company (GE). See "Dependency on a
    Single Customer." 

    Government Regulation

        The Company's products and its research, development, and
    manufacturing activities are subject to regulation by numerous
    governmental authorities in the United States and other countries. In the
    United States, medical devices are subject to rigorous FDA review. The
    federal Food, Drug, and Cosmetic Act, the Public Health Services Act, and
    other federal statutes and regulations govern or influence the testing,
    manufacture, safety, labeling, storage, record-keeping, reporting,
    approval, advertising, and promotion of products such as those offered by
    the Company. Noncompliance with applicable requirements can result in
    fines, recalls, or seizures of products, total or partial suspension of
    production, and criminal prosecution.

        The Company is also subject to periodic inspections by the FDA, which
    audits the Company's compliance with current good manufacturing practices
    as set forth in the quality system regulation (QSR) during such
    inspections. Enforcement of QSR regulations has increased significantly
    in the last several years. In the event that the Company or any of its
    facilities was determined to be in noncompliance, and to the extent that
    the Company or such facility was unable to convince the FDA of the
    adequacy of its compliance, the FDA has the power to assert penalties or
    remedies, including a recall or temporary suspension of product shipments
    until compliance is achieved. Such penalties or remedies could have a
    material adverse effect on the Company's business and results of
    operations.

        The Company is also regulated by the FDA under the Radiation Control
    for Health and Safety Act of 1968 (Public Law 90-602), which specifically
    addresses radiation-emitting products. Under this law, the Company is
    responsible for submitting initial reports on all new X-ray systems that
    require certification to FDA performance standards, as well as annual
    reports and reports of accidental radiation occurrences.

                                        8PAGE
<PAGE>
        Historically, the Company has been subject to recalls of certain of
    its products from time to time under Public Law 90-602. Under this law,
    the manufacturer must repair, replace, or refund the cost of any product
    that is not in compliance with the relevant performance standard.

        (ii) and (xi) New Products; Research and Development

        The Company maintains active programs for the development of new
    mammography and X-ray imaging systems. The Company's current development
    efforts are focused on the development of a full-field digital
    mammography system, X-ray sensors for flat-panel direct-detection
    digital-imaging technology, the enhancement of existing mammography
    products, and the introduction of an interventional radiology product.
    The Company believes that the digital-imaging technology developed for
    this system also may be adaptable to general-purpose and specialized
    X-ray systems.

        The Company is developing products based on flat-panel direct-
    detection digital-imaging technology being developed by scientists at
    ThermoTrex. ThermoTrex has granted the Company a fully paid, exclusive,
    worldwide, perpetual license to use such technology in the fields of
    mammography and general radiography. Under the terms of the license
    agreement with ThermoTrex, if the Company elects to fund approximately
    $6.0 million of the research and development in the fields of R/F, mobile
    C-arm fluoroscopy, and cardiography/angiography over a three-year period,
    the Company's license will be extended to cover such fields. As of
    September 27, 1997, the Company had cumulatively funded $3.8 million
    under the agreement.

        Research and development expenses of the Company were $24.7 million,
    $18.9 million, and $8.6 million for fiscal 1997, fiscal 1996, and the
    nine months ended September 30, 1995.

        (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's policy is to protect its intellectual property rights
    and to apply for patent protection when appropriate. The Company
    currently holds numerous issued United States patents expiring at various
    dates ranging from 2003 to 2014. The Company also has more than 10
    applications pending for additional United States patents and a number of
    foreign counterparts for its patents in various foreign countries. Patent
    protection provides the Company with competitive advantages with respect
    to certain systems. The Company believes, however, that technical
    know-how and trade secrets are more important to its business than patent
    protection.

<PAGE>
        Competitors of the Company and other third parties hold issued
    patents and pending patent applications relating to imaging and other
    related technologies, and it is uncertain whether these patents and
    patent applications will require the Company to alter its products or
    processes, pay licensing fees, or cease certain activities. See
    information under the heading "Risks Associated With Pending and
    Threatened Patent Litigation" under the caption "Forward-looking
    Statements" in the Registrant's Fiscal 1997 Annual Report to
    Shareholders, which statements are incorporated herein by reference, and
    "Item 3 - Legal Proceedings."

        (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

        Revenues from OEM sales of a modified design of the Company's
    stereotactic prone breast-biopsy system to U.S. Surgical accounted for
    17% of the Company's total revenues in fiscal 1997.

        (viii) Backlog

        The backlog of firm orders was $54.3 million as of September 27,
    1997, compared with $71.7 million as of September 28, 1996. The backlog
    at September 28, 1996, was affected by a build-up of new orders for the
    Company's M-IV mammography system, which the Company began shipping in
    late fiscal 1996, and the timing of certain orders received in late
    fiscal 1996. Accordingly, the Company does not believe that the decline
    in backlog is indicative of a trend. The Company anticipates that
    substantially all of the backlog at September 27, 1997, will be shipped
    during fiscal 1998.

        (ix) Government Contracts

        Not applicable.

        (x) Competition

        The healthcare industry in general, and the market for imaging
    products in particular, is highly competitive. The Company competes with
    a number of companies, many of which have substantially greater
    financial, marketing, and other resources than the Company. The Company's
    competitors include large companies such as GE, the Philips Medical
    Systems North America Company subsidiary of Philips N.V. (Philips), the
    Siemens Corporation subsidiary of Siemens AG (Siemens), Toshiba American
    Medical Systems, Inc., Toshiba America MRI, Inc., Shimadzu, and Picker

                                       10PAGE
<PAGE>
    International, Inc., which compete in most diagnostic imaging modalities,
    including X-ray imaging. In addition, a significant portion of the
    Company's sales are to U.S. Surgical and GE through OEM arrangements. The
    products sold through such OEM agreements compete with those offered by
    the Company directly and through its independent dealers. The Company's
    StereoLoc II, Cytoguide, and StereoGuide breast-biopsy systems compete
    with products offered by GE, Fischer Imaging Corporation, and Philips,
    and with conventional surgical biopsy procedures. The Company competes
    primarily on the basis of product features, product performance, and
    reputation as well as price and service. The Company believes that
    competition is likely to increase as a result of healthcare
    cost-containment pressures and the development of alternative diagnostic
    and interventional technologies.

        (xii) Environmental Protection Regulations

        The Company believes that compliance with federal, state, and local
    environmental regulations will not have a material adverse effect on its
    capital expenditures, earnings, or competitive position. 

        (xiii) Number of Employees

        As of September 27, 1997, the Company employed 1,041 persons.

    (d) Financial Information about Exports by Domestic Operations

        Financial information about exports by domestic operations is
    summarized in Note 8 to Consolidated Financial Statements in the
    Registrant's Fiscal 1997 Annual Report to Shareholders, which information
    is incorporated herein by reference.

                                        and Director (1995)
    John N. Hatsopoulos        63     Chief Financial Officer and Vice

    Paul F. Kelleher           55     Chief Accounting Officer (1995)

        Each executive officer serves until his successor is chosen or
    appointed by the Board of Directors and qualified, or until earlier
    resignation, death, or removal. Messrs. Hatsopoulos and Kelleher have
    held comparable positions for at least five years with the Company or
    Thermo Electron. Mr. Kirshner was President of Lorad from February 1991
    to April 1997. Mr. Brenna has been a Vice President since joining the
    Company in March 1996. Prior to joining the Company, Mr. Brenna was
    Director of Marketing, North America, for Philips Medical Systems, a
    position he held for seven years. Messrs. Hatsopoulos and Kelleher are
    full-time employees of Thermo Electron but devote such time to the
    affairs of the Company as the Company's needs reasonably require.

    Item 2. Properties

        The Company owns two office and manufacturing facilities: a 62,500-
    square-foot facility in Danbury, Connecticut, and a 143,000-square-foot
    facility in Broadview, Illinois. The Company leases a 120,000-square-foot
    office and manufacturing facility in Copiague, New York, under a lease
    expiring in 2005, a 156,000-square-foot office and manufacturing facility
    in Littleton, Massachusetts, under a lease expiring in 2012, and a
    60,000-square-foot office and manufacturing facility in Danbury,
    Connecticut, under a lease expiring in 2007.

        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 the Company's Lorad division, alleging that Lorad's prone breast-
    biopsy system infringes a Fischer patent on a precision mammographic
    needle-biopsy system. As of September 27, 1997, the Company had
    recognized aggregate revenues of approximately $107.1 million from the
    sale of such systems, of which $34.4 million represents sales prior to
    October 16, 1995. The suit requests a permanent injunction, treble
    damages, and attorneys' fees and expenses. If the Company is unsuccessful
    in defending this lawsuit, it may be enjoined from manufacturing and
    selling its prone breast-biopsy system without a license from Fischer. No
    assurance can be given that the Company will be able to obtain such a
    license, if required, on commercially reasonable terms, if at all. In
    addition, the Company may be subject to damages for past infringement. No
    assurance can be given as to the amount that the Company may eventually
    be required to pay in expenses or in such damages.

        In connection with the organization of the Company, ThermoTrex agreed
    to indemnify the Company for any and all cash damages in connection with
    the Fischer lawsuit with respect to sales of the Company's products
    occurring prior to October 16, 1995, when Lorad was transferred to the
    Company. Notwithstanding this indemnification, the Company would be
    required to report as an expense in its results of operations the full
    amount, including any reimbursable amount, of any damages in excess of
    the amount accrued (approximately $2 million as of September 27, 1997),
    with any indemnification payment it receives from ThermoTrex being
    treated as a contribution to shareholders' investment.

                    Report of Independent Public Accountants

    To the Shareholders and Board of Directors of Trex Medical Corporation:

        We have audited, in accordance with generally accepted auditing
    standards, the consolidated financial statements included in Trex Medical
    Corporation's Annual Report to Shareholders incorporated by reference in
    this Form 10-K, and we have issued our report thereon dated November 3,
    1997. Our audits were made for the purpose of forming an opinion on the
    basic consolidated financial statements taken as a whole. The schedule
    listed in Item 14 on page 15 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. This 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 financial data required to be set forth therein in relation to the
    basic consolidated financial statements taken as a whole.

        the transfer of funds by Buyer, with a simultaneous agreement by
        Buyer to transfer to Seller such Securities on demand, against

        Seller) plus 25 basis points,  which rate shall be adjusted on
        the first business day of each fiscal quarter and shall be in
        effect for the entirety such fiscal quarter;
         
             (g)  "Purchase Price", the price at which Purchased

        Purchased Securities; and

        amount equal to the Purchase Price paid by Buyer to Seller for
        such Purchased Security. 

        3.   Transactions

             (a)  A Transaction may be initiated by Buyer upon the
        transfer of the Purchase Price to Seller's account.  Upon such
        transfer, Seller shall transfer to Buyer Purchased Securities
        having a Market Value equal to 103% of the Purchase Price.

             (b)  Purchased Securities shall be held in custody for Buyer
        by Seller in the Repurchase Collateral Account.  Seller shall
        indicate on its books for such account Buyer's ownership of the
        Purchased Securities.  Upon reasonable request from Buyer, Seller
        shall provide Buyer with a complete list of Purchased Securities
        owned by Buyer.  

             (c)  Upon demand by Buyer or Seller, Seller shall repurchase

        Price all or any part of the Purchased Securities then owned by
        Buyer.

                                        2PAGE
<PAGE>
        4.   Margin Maintenance

             (a)  If at any time the aggregate Market Value of all
        Purchased Securities then owned by Buyer is less than 103% of the
        aggregate Repurchase Price for such Purchased Securities, then
        Seller shall transfer to Buyer additional Securities ("Additional
        Purchased Securities"), so that the aggregate Market Value of
        such Purchased Securities, including any such Additional
        Purchased Securities, will thereupon equal or exceed  103% of
        such aggregate Repurchase Price.

             (b)  If at any time the aggregate Market Value of all
        Purchased Securities then owned by Buyer exceeds 103% of the
        aggregate Repurchase Price for such Purchased Securities, then
        Seller may transfer Purchased Securities to Seller, so that the
        aggregate Market Value of such Purchased Securities will
        thereupon not exceed 103% of such aggregate Repurchase Price.

        5.   Interest Payments

             If during any fiscal month Buyer owned Purchased Securities,
        then on the first day of the next following fiscal month Seller
        shall pay to Buyer an amount equal to the sum of the aggregate
        Repurchase Prices of the Purchased Securities owned by Buyer at
        the close of each day during the preceding fiscal month divided
        by the number of days in such month and the product multiplied by
        the Pricing Rate times the number of days in such month divided
        by 360.

        6.   Income Payments and Voting Rights

             Where a particular Transaction's term extends over an Income
        payment date on the Purchased Securities subject to that
        Transaction, Buyer shall, on the date such Income is payable,
        transfer to Seller an amount equal to such Income payment or
        payments with respect to any Purchased Securities subject to such
        Transaction.  Seller shall retain all voting rights with respect
        to Purchased Securities sold to Buyer under this Agreement.

        7.   Security Interest

             Although the parties intend that all Transactions hereunder
        be sales and purchases and not loans, in the event any such
        Transactions are deemed to be loans, Seller shall be deemed to
        have pledged to Buyer as security for the performance by Seller
        of its obligations under each such Transaction and this
        Agreement, and shall be deemed to have granted to Buyer a
        security interest in, all of the Purchased Securities with
        respect to all Transactions hereunder and all proceeds thereof.

                                        3PAGE
<PAGE>
        8.   Payment and Transfer

             Unless otherwise mutually agreed, all transfers of funds
        hereunder shall be in immediately available funds.  As used
        herein with respect to Securities, "transfer" is intended to have
        the same meaning as when used in Section 8-313 of the
        Massachusetts Uniform Commercial Code or, where applicable, in
        any federal regulation governing transfers of the Securities.

        9.   Substitution

             Buyer hereby grants Seller the authority to manage, in
        Seller's sole discretion, the Purchased Securities held in
        custody for Buyer by Seller in the Repurchase Collateral Account.
        Buyer expressly agrees that Seller may (i) substitute other
        Securities for any Purchased Securities and (ii) commingle
        Purchased Securities with other Securities held in the Repurchase
        Collateral Account.  Substitutions shall be made by transfer to
        Buyer of such other Securities and transfer to Seller of the
        Purchased Securities for which substitution is being made.  After
        substitution, the substituted Securities shall be deemed to be
        Purchased Securities.  Securities which are substituted for
        Purchased Securities shall have a Market Value at the time of
        substitution equal to or greater than the Market Value of the
        Purchase Securities for which such Securities were substituted.

        10.  Representations

             Each of Buyer and Seller represents and warrants to the
        other that (i) it is duly authorized to execute and deliver this
        Agreement, to enter into the Transactions contemplated hereunder
        and to perform its obligations hereunder and has taken all
        necessary action to authorize such execution, delivery and
        performance, (ii) the person signing this Agreement on its behalf
        is duly authorized to do so on its behalf, (iii) it has obtained
        all authorizations of any governmental body required in
        connection with this Agreement and the Transactions hereunder and
        such authorizations are in full force and effect and (iv) the
        execution, delivery and performance of this Agreement and the
        Transactions hereunder will not violate any law, ordinance,
        charter, by-law or rule applicable to it or any agreement by
        which it is bound or by which any of its assets are affected.  On
        the date for any Transaction Buyer and Seller shall each be
        deemed to repeat all the foregoing representations made by it.

        11.  Events of Default

             In the event that (i) Seller fails to repurchase or Buyer
        fails to transfer Purchased Securities upon demand for repurchase
        from either Buyer or Seller, (ii)  Seller or Buyer fails, after
        one business day's notice, to comply with Paragraph 4 hereof,
        (iii) Buyer  fails to make payment to Seller pursuant to  
        Paragraph 6 hereof, (iv) Seller fails to comply with Paragraph 5
        hereof,  (v) an Act of Insolvency occurs with respect to Seller

                                        4PAGE
<PAGE>
        or Buyer, (vi) any representation made by Seller or Buyer shall
        have been incorrect or untrue in any material respect when made
        or repeated or deemed to have been made or repeated, or (vii)
        Seller or Buyer shall admit to the other its inability to, or its
        intention not to, perform any of its obligations hereunder (each
        an "Event of Default"):

             (a)  At the option of the nondefaulting party, exercised by
        written notice to the defaulting party (which option shall be
        deemed to have been exercised, even if no notice is given,
        immediately upon the occurrence of any Act of Insolvency), Seller
        shall become obligated to repurchase, and Buyer shall become
        obligated to sell, all Purchased Securities then owned by Buyer
        for the Repurchase Price of such Purchased Securities.

             (b)  If Seller is the defaulting party and Buyer exercises
        or is deemed to have exercised the option referred to in
        subparagraph (a) of this Paragraph, (i) the Seller's obligations
        hereunder to repurchase all Purchased Securities in such
        Transactions shall thereupon become immediately due and payable,
        (ii) all Income paid after such exercise or deemed exercise shall
        be retained by Buyer and applied to the aggregate unpaid
        Repurchase Prices owed by Seller, and (iii) Seller shall
        immediately deliver to Buyer any Purchased Securities subject to
        such Transactions then in Seller's possession.

             (c)  In all Transactions in which Buyer is the defaulting
        party, upon tender by Seller of payment of the aggregate
        Repurchase Prices for all such Transactions, Buyer's right, title
        and interest in all Purchased Securities subject to such
        Transactions shall be deemed transferred to Seller, and Buyer
        shall deliver all such Purchased Securities to Seller.

             (d)  After one business day's notice to the defaulting party
        (which notice need not be given if an Act of Insolvency shall
        have occurred, and which may be the notice given under
        subparagraph (a) of this Paragraph or the notice referred to in
        clause (ii) of the first sentence of this Paragraph), the
        nondefaulting  party may: 

                  (i)  as to Transactions in which Seller is the
        defaulting party, (A) immediately sell, in a recognized market at
        such price or prices as Buyer may reasonably deem satisfactory,
        any or all Purchased Securities subject to such Transactions and
        apply the proceeds thereof to the aggregate unpaid Repurchase
        Prices and any other amounts owing by Seller hereunder or (B) in
        its sole discretion elect, in lieu of selling all or a portion of
        such Purchased Securities, to give Seller credit for such
        Purchased Securities in an amount equal to the price therefor on
        such date, obtained from a generally recognized source or the
        most recent closing bid quotation from such a source, against the

        Securities that are not delivered by Buyer to Seller as required

             Buyer and Seller acknowledge that, and have entered hereinto
        and will enter into each Transaction hereunder in consideration
        of and in reliance upon the fact that, all Transactions hereunder

        have been made in consideration of each other.  Accordingly, each
        of Buyer and Seller agrees (i) to perform all of its obligations
        in respect of each Transaction hereunder, and that a default in
        the performance of any such obligations shall constitute a
        default by it in respect of all Transactions hereunder, (ii) that
        each of them shall be entitled to set off claims and apply
        property held by them in respect of any Transaction against
        obligations owing to them in respect of any other Transactions
        hereunder and (iii) that payments, deliveries and other transfers
         made by either of them in respect of any Transaction shall be
        deemed to have been made in consideration of payments, deliveries

        hereunder, and the obligations to make any such payments,
        deliveries and other transfers may be applied against each other
        and netted.

        13.  Entire Agreement; Severability

             This Agreement shall supersede any existing agreements
        between the parties containing general terms and conditions for
        repurchase transactions.  Each provision and agreement and
        agreement herein shall be treated as separate and independent
        from any other provision or agreement herein and shall be
        enforceable notwithstanding the unenforceability of any such
        other provision or agreement.

        14.  Non-assignability; Termination

             The rights and obligations of the parties under this
        Agreement and under any Transactions shall not be assigned by
        either party without the prior written consent of the other
        party.  Subject to the foregoing, this Agreement and any
        Transactions shall be binding upon and shall inure to the benefit
        of the parties and their respective successors and assigns.  This
        Agreement may be canceled by either party upon giving written
        notice to the other, except that this Agreement shall,
        notwithstanding such notice, remain applicable to any
        Transactions then outstanding.

        15.  Governing Law

             This Agreement shall be governed by the laws of the
        Commonwealth of Massachusetts without giving effect to the
        conflict of law principles thereof.

        16.  No Waivers, Etc.

             No express or implied waiver of any Event of Default by
        either party shall constitute a waiver of any other Event of
        Default and no exercise of any remedy hereunder by any party
        shall constitute a wavier of its right to exercise any other
        remedy hereunder.  No modification or waiver of any provision of
        this Agreement and no consent by any party to a departure
        herefrom shall be effective unless and until such shall be in
        writing and duly executed by both of the parties hereto. 

        19.  Intent

             (a)  The parties recognize that each Transaction is a
        "repurchase agreement" as that term is defined in Section 101 of
        Title 11 of the United States Code, as amended (except insofar as
        the type of Securities subject to such Transaction or the term of
        such Transaction would render such definition inapplicable), and
        a "securities contract" as that term is defined in Section 741 of
        Title 11 of the United States Code, as amended.

             (b)  It is understood that either party's right to liquidate
        Securities delivered to it in connection with Transactions
        hereunder or to exercise any other remedies pursuant to Paragraph
        11 hereof, is a contractual right to liquidate such Transaction

                                        7PAGE
<PAGE>
        as described in Sections 555 and 559 of Title 11 of the United
        States Code, as amended.

             IN WITNESS WHEREOF, the parties have executed this Agreement
        as of the date first above written.

                            TREX MEDICAL CORPORATION

                     RESTATED STOCK HOLDING ASSISTANCE PLAN

        SECTION 1.   Purpose.

             The purpose of this Plan is to benefit Trex Medical
        Corporation (the "Company") and its stockholders by encouraging
        Key Employees to acquire and maintain share ownership in the
        Company, by increasing such employees' proprietary interest in
        promoting the growth and performance of the Company and its
        subsidiaries and by providing for the implementation of the Stock
        Holding Policy.  

        SECTION 2.     Definitions.

             The following terms, when used in the Plan, shall have the
        meanings set forth below:

             Committee:   The Human Resources Committee of the Board of
        Directors of the Company as appointed from time to time.

             Common Stock:   The common stock of the Company and any
        successor thereto.

             Company:   Trex Medical Corporation, a Delaware corporation.

             Stock Holding Policy:   The Stock Holding Policy of the
        Company, as adopted by the Committee and as in effect from time
        to time.

             Key Employee:   Any employee of the Company or any of its
        subsidiaries, including any officer or member of the Board of
        Directors who is also an employee, as designated by the
        Committee, and who, in the judgment of the Committee, will be in
        a position to contribute significantly to the attainment of the
        Company's strategic goals and long-term growth and prosperity.

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

             Plan:   The Trex Medical 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
        interpretations and decisions with regard to the Plan and the
PAGE
<PAGE>
        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 in
        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 on the fifth anniversary of the date of
        the Loan, provided that the Committee may, in its sole and
PAGE
<PAGE>
        absolute discretion, authorize such other maturity and repayment
        schedule as the Committee may determine.  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.

             The Plan and the Stock Holding Policy shall become effective
        upon approval and adoption by the Committee.

                                                Dated:____________

             For value  received, ________________,  an individual  whose
        residence is located at _______________________ (the "Employee"),
        hereby  promises  to  pay   to  Trex  Medical  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 to the  Company
        from the Employee's annual cash incentive compensation  (referred
        to as  bonus), 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  occurring prior to  the Maturity Date,  such
        amount as may be  designated by the Company  but which shall  not
        exceed 20% of the Employee's bonus payment.  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
<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

    1.  Nature of Operations and Summary of Significant Accounting Policies

    Nature of Operations
        Trex Medical Corporation (the Company) designs, manufactures, and
    markets mammography equipment and minimally invasive digital breast-
    biopsy systems used for the detection of breast cancer. The Company also
    designs and manufactures general-purpose X-ray equipment and specialized
    X-ray equipment, including imaging systems used during diagnostic and
    interventional vascular and cardiac procedures such as balloon
    angioplasty. The Company's mammography and digital breast-biopsy systems
    are used by radiologists and physicians in offices, hospitals, and
    dedicated breast-care centers, and its general-purpose X-ray systems are
    used by physicians and radiologists, both in office and hospital
    settings, as well as by veterinarians and chiropractors.

    Relationship with ThermoTrex Corporation and Thermo Electron Corporation
        The Company was incorporated in September 1995 as a wholly owned
    subsidiary of ThermoTrex Corporation (ThermoTrex). On October 2, 1995,
    ThermoTrex transferred to the Company all of the outstanding shares of
    capital stock of Bennett X-Ray Corporation (Bennett), in exchange for a
    $42.0 million principal amount 4.2% subordinated convertible note 
    (Note 7). As of September 27, 1997, ThermoTrex had converted $34.0
    million principal amount of this note. On October 16, 1995, ThermoTrex
    transferred to the Company the assets, liabilities, and businesses of
    ThermoTrex's Lorad division (Lorad) and ThermoTrex's research and
    development activities pertaining to its Sonic CT(TM) system, in exchange
    for 20,000,000 shares of the Company's common stock. ThermoTrex acquired
    Lorad and Bennett in November 1992 and September 1995, respectively.
        As of September 27, 1997, ThermoTrex owned 22,883,798 shares of the
    Company's common stock, representing 79% of such stock outstanding.
    ThermoTrex is a 53%-owned subsidiary of Thermo Electron Corporation
    (Thermo Electron).

    Principles of Consolidation
        The accompanying financial statements include the accounts of the
    Company and its wholly owned 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 1997 and fiscal
    1996 are for the years ended September 27, 1997, and September 28, 1996,
    respectively. Fiscal 1997 and fiscal 1996 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.

    Trex Medical Corporation                        1997 Financial Statements

                   Notes to Consolidated Financial Statements

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

    Revenue Recognition
        The Company recognizes revenues upon shipment of its products. The
    Company provides a reserve for its estimate of warranty costs at the time
    of shipment.

    Concentration of Credit Risk
        The Company sells its products primarily to customers in the
    healthcare industry. The Company 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.

    Stock-based Compensation Plans
        The Company applies Accounting Principles Board Opinion (APB) No. 25,
    "Accounting for Stock Issued to Employees" and related interpretations in
    accounting for its stock-based compensation plans (Note 4). Accordingly,
    no accounting recognition is given to stock options granted at fair
    market value until they are exercised. Upon exercise, net proceeds,
    including tax benefits realized, are credited to equity.

    Income Taxes
        The Company and ThermoTrex entered into a tax allocation agreement
    under which the Company was included in the consolidated income tax
    returns filed by ThermoTrex. The agreement provided that in years in
    which the Company had taxable income, it would pay to ThermoTrex amounts
    comparable to the taxes the Company would have paid if it had filed
    separate tax returns. Subsequent to the Company's sale of common stock in
    December 1996 (Note 3), ThermoTrex's ownership of the Company was reduced
    below 80% and, as a result, the Company is required to file its own
    income tax returns.
        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 has been computed based on the weighted average
    number of shares outstanding during the period. Weighted average shares
    for fiscal 1996 and 1995 include the effect of the assumed exercise of
    stock options issued within one year prior to the Company's initial
    public offering. Because the effect of the assumed exercise of stock
    options would be immaterial, they have been excluded from the primary
    earnings per share calculation subsequent to the Company's initial public
    offering. Fully diluted earnings per share in fiscal 1996 include the
    effect of the assumed exercise of stock options and the effect of the
    assumed conversion of the Company's 4.2% subordinated convertible note,
    due to parent company.

        (continued)

    Cash and Cash Equivalents
        As of September 27, 1997, $34,587,000 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 U.S. government-agency securities, corporate
    notes, commercial paper, money market funds, 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. 

    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 consists of the

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

    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 $5,807,000 and $3,621,000 as of September
    27, 1997, and September 28, 1996, 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. If impairment
    has occurred, any excess of carrying value over fair value is recorded as
    a loss.

    Use of Estimates
        The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities,
    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 1996 have been reclassified to conform to
    the presentation in the fiscal 1997 financial statements.

    2.  Acquisitions

        In September 1996, the Company acquired substantially all of the
    assets and liabilities of Continental X-Ray Corporation and affiliates
    (Continental), an Illinois-based company that designs, manufactures, and
    markets general-purpose and specialized X-ray systems, for approximately
    $18.4 million in cash, net of cash acquired and including the repayment
    of debt.
        In May 1996, the Company acquired substantially all of the assets and
    liabilities of XRE Corporation (XRE), a Massachusetts-based company that
    designs, manufactures, and markets X-ray imaging systems used in the
    diagnosis and treatment of coronary artery disease and other vascular
    conditions, for approximately $18.5 million in cash, net of cash acquired
    and including the repayment of debt.
        In September 1995, ThermoTrex acquired all of the outstanding capital
    stock of Bennett, a New York-based manufacturer of high-frequency
    specialty and general-purpose X-ray systems, for approximately $42.9
    million in cash. On October 2, 1995, ThermoTrex transferred to the
    Company all of the outstanding capital stock of Bennett, in exchange for
    a $42.0 million principal amount 4.2% subordinated convertible note
    (Note 7).

    2.  Acquisitions (continued)

        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 by the Company, or for Bennett, by ThermoTrex. The cost of
    the acquisitions exceeded the estimated fair value of the acquired net
    assets by $63.5 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.
        Based on unaudited data, the following table presents selected
    financial information for the Company and the businesses acquired on a
    pro forma basis, assuming they had been combined since the beginning of
    fiscal 1995. 

                                                                       Nine

    -----------------------------------------------------------------------
    Revenues                                       $191,351        $126,185
    Net income                                        9,300           2,012
    Earnings per share:
      Primary                                           .29             .07
      Fully diluted                                     .29             .07

        The pro forma results are not necessarily indicative of future
    operations or the actual results that would have occurred had the
    acquisitions been made at the beginning of 1995.
        Other accrued expenses in the accompanying balance sheet includes
    $2.5 million and $3.5 million as of September 27, 1997, and September 28,
    1996, respectively, 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
    ThermoTrex's acquisition of Lorad. This suit was brought by Fischer
    Imaging Corporation (Fischer), alleging that Lorad infringes a Fischer
    patent on a precision mammographic needle-biopsy system. In connection
    with the organization of the Company, ThermoTrex agreed to indemnify the
    Company for any and all cash damages under this lawsuit, with respect to
    sales occurring prior to October 16, 1995, the date Lorad was transferred
    to the Company. Any payments received under such indemnity would be
    treated as a contribution to shareholders' investment. While the Company
    believes that 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, management does not believe that it is reasonably likely that
    any resolution would have a material adverse effect on the Company's
    financial position.

    3.  Common Stock

    Sale of Common Stock
        In December 1996, the Company sold 300,000 shares of its common stock
    at $14.50 per share, for net proceeds of $4,119,000. 
        In July 1996, the Company sold 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
    $49,068,000.
        In November 1995, the Company issued 1,862,000 shares of its common
    stock in a private placement at $10.25 per share for net proceeds of
    $17,619,000. In January 1996, the Company issued 100,000 shares of its
    common stock in a private placement at $10.75 per share for net proceeds
    of $1,070,000. Certain officers and directors of the Company purchased an
    aggregate of 143,300 shares of the Company's common stock issued in these
    private placements. In addition, an entity indirectly related to a
    director of the Company purchased 200,000 shares of the Company's common
    stock issued in these private placements. This director, however,
    disclaims beneficial ownership of such shares.

    Conversion of Subordinated Convertible Note
        During fiscal 1996, ThermoTrex converted $34,000,000 principal amount
    of the Company's 4.2% subordinated convertible note into 2,883,798 shares
    of the Company's common stock.

    Reserved Shares
        As of September 27, 1997, the Company had reserved 2,801,542 unissued
    shares of its common stock for possible issuance under stock-based
    compensation plans and conversion of the Company's 4.2% subordinated
    convertible note, due to parent company.

    4.  Employee Benefit Plans

    Stock-based Compensation Plans

    Stock Option Plans
    ------------------
        In 1995 and 1997, the Company adopted stock-based compensation plans
    for its key employees, directors, and others, which permit the grant of a
    variety of stock and stock-based awards as determined by the human
    resources committee of the Company's Board of Directors (the Board
    Committee), including restricted stock, stock options, stock bonus shares
    or performance-based shares. To date, only nonqualified stock options
    have been awarded under these plans. The option recipients and the terms
    of options granted under these plans are determined by 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 a five- to ten-year
    period, depending on the term of the option, which may range from seven
    to twelve years. Nonqualified stock options may be granted at any price

    4.  Employee Benefit Plans (continued)

    determined by the Board Committee, although incentive stock options must
    be granted at not less than the fair market value of the Company's common
    stock on the date of grant. To date, all options have been granted at
    fair market value. The Company also has a directors' stock option plan,
    adopted in 1995, that provides for the grant of stock options to outside
    directors pursuant to a formula approved by the Company's shareholders.
    Options granted under this plan have the same general terms as options
    granted under the stock-based compensation plans described above, except
    that the restrictions and repurchase rights generally lapse ratably over
    a four-year period and the option term is five years. In addition to the
    Company's stock-based compensation plans, certain officers and key
    employees may also participate in the stock-based compensation plans of
    Thermo Electron and ThermoTrex.
        A summary of the Company's stock option information is as follows:

    Employee Stock Purchase Program
    -------------------------------
        Effective November 1, 1997, substantially all of the Company's
    full-time employees are eligible to participate in an employee stock
    purchase program sponsored by the Company and Thermo Electron, under
    which employees can purchase shares of the Company's and Thermo
    Electron's common stock. Prior to November 1, 1997, the program was
    sponsored by ThermoTrex and Thermo Electron. Under this program, the
    applicable shares of common stock can be purchased at the end of a
    12-month period at 95% of the fair market value at the beginning of the
    period, 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 period, 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.

    Pro Forma Stock-based Compensation Expense
        In October 1995, the Financial Accounting Standards Board issued SFAS
    No. 123, "Accounting for Stock-based Compensation," which sets forth a
    fair-value based method of recognizing stock-based compensation expense.
    As permitted by SFAS No. 123, the Company has elected to continue to
    apply APB No. 25 to account for its stock-based compensation plans. Had
    compensation cost for awards in fiscal 1997 and 1996 under the Company's
    stock-based compensation plans been determined based on the fair value at

    4.  Employee Benefit Plans (continued)

    the grant dates consistent with the method set forth under SFAS No. 123,
    the effect on the Company's net income and earnings per share would have
    been as follows:

        Because the method prescribed by SFAS No. 123 has not been applied to
    options granted prior to October 1, 1995, the resulting pro forma
    compensation expense may not be representative of the amount to be
    expected in future years. Compensation expense for options granted is
    reflected over the vesting period; therefore, future pro forma
    compensation expense may be greater as additional options are granted.
        The fair value of each option grant was estimated on the grant date
    using the Black-Scholes option-pricing model with the following
    weighted-average assumptions:

                                                            1997       1996
    -----------------------------------------------------------------------
    Volatility                                               26%        29%
    Risk-free interest rate                                 6.5%       6.4%
    Expected life of options                           8.5 years  7.8 years

        The Black-Scholes option-pricing model was developed for use in
    estimating the fair value of traded options which have no vesting
    restrictions and are fully transferable. In addition, option-pricing
    models require the input of highly subjective assumptions including
    expected stock price volatility. Because the Company's employee stock
    options have characteristics significantly different from those of traded
    options, and because changes in the subjective input assumptions can
    materially affect the fair value estimate, in management's opinion, the
    existing models do not necessarily provide a reliable single measure of
    the fair value of its employee stock options.

    4.  Employee Benefit Plans (continued)

    401(k) Savings Plan
        The majority of the Company's full-time employees are eligible to
    participate in Thermo Electron's 401(k) savings plan. 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.
    The Company contributed and charged to expense for these plans
    $1,080,000, $701,000, and $242,000 in fiscal 1997, 1996, and 1995,
    respectively.

    5.  Income Taxes

        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 $982,000 and $186,000 of such benefits that have been
    allocated to capital in excess of par value for fiscal 1997 and 1996,
    respectively.

        The provision for income taxes in the accompanying statement of
    income for fiscal 1997, 1996, and 1995 differs from the provision
    calculated by applying the statutory federal income tax rate of 35% in

    for income taxes due to the following:

  6.  Commitments

        The Company leases portions of its office and operating facilities
    under various noncancelable operating lease arrangements expiring between
    fiscal 1998 and fiscal 2007. The accompanying statement of income
    includes expenses from these operating leases of $1,408,000, $674,000,
    and $44,000 in fiscal 1997, 1996, and 1995, respectively. Future minimum
    payments due under these noncancelable operating leases at September 27,
    1997, are $1,411,000 in fiscal 1998; $1,383,000 in fiscal 1999;
    $1,374,000 in fiscal 2000; $1,372,000 in fiscal 2001; $1,402,000 in
    fiscal 2002; and $5,007,000 in fiscal 2003 and thereafter. Total future
    minimum lease payments are $11,949,000. The Company also has an operating
    lease arrangement with a related party as discussed in Note 7.

    7.  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% of the Company's revenues in calendar
    year 1995. The annual fee is reviewed and adjusted annually by mutual
    agreement of the parties. For these services, the Company was charged
    $2,293,000, $1,567,000, and $663,000 in fiscal 1997, 1996, and 1995,
    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 relationship 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.

    Related-party Revenues
        ThermoLase Corporation (ThermoLase), a majority-owned subsidiary of
    ThermoTrex, has engaged the Company to design and manufacture the laser
    used in ThermoLase's laser-based hair-removal system. During fiscal 1997,
    1996, and 1995, the Company recorded $11,390,000, $8,549,000, and
    $350,000, respectively, of revenue under this arrangement.
        Under an arrangement with Thermedics Detection Inc., a majority-owned
    subsidiary of Thermo Electron, the Company manufactures an X-ray source,
    pursuant to written purchase orders, that is used as a component in a
    fill-measuring device produced by Thermedics Detection. During fiscal
    1997, 1996, and 1995, the Company recorded $37,000, $361,000, and
    $120,000, respectively, of revenue under this arrangement.

    Vendor Agreement
        During 1995, the Company 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 are expected to be received
    through fiscal 1999. During fiscal 1997 and 1996, the Company purchased
    grids valued at $678,000 and $397,000 from Tecomet under this
    arrangement. In addition, the Company recorded expense of $250,000 during
    fiscal 1995 related to research and development funding provided to
    Tecomet in connection with this project.

    7.  Related-party Transactions (continued)

    Research and Development Agreement
        In October 1995, the Company and ThermoTrex entered into a license
    agreement under which the Company may elect to fund approximately $6.0
    million of ThermoTrex's research and development efforts related to
    direct-detection digital imaging technology in certain medical imaging
    fields. If the Company elects to fund such costs, it is required to pay
    approximately $2,000,000 in each of three years through 1998 and its
    license will be extended to cover such fields. In fiscal 1997 and 1996,
    the Company recorded $2,000,000 and $1,800,000 of expense under this
    agreement. Prior to this agreement, ThermoTrex provided certain research
    and development contract services to the Company, which were charged to
    the Company based on actual cost and usage. For these services, the
    Company was charged $1,536,000 in fiscal 1995.

    Operating Lease
        The Company leases an office and operating facility from a realty
    trust controlled by an employee under a noncancelable operating lease
    arrangement expiring in fiscal 2012. The accompanying statement of income
    includes expenses from this operating lease of $982,000 and $286,000 in
    fiscal 1997 and 1996, respectively. Future minimum payments due under
    this noncancelable operating lease at September 27, 1997, are $982,000
    per year in fiscal 1998, 1999, 2000, 2001, and 2002, and $9,497,000 in
    fiscal 2003 and thereafter. Total future minimum lease payments are
    $14,407,000.
        Additionally, the Company leases certain office space from ThermoTrex
    on a month-to-month basis. The accompanying statement of income includes
    expenses from this operating lease of $43,000, $7,000, and $5,000 in
    fiscal 1997, 1996, and 1995, respectively.

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

    Subordinated Convertible Note
        In September 1995, ThermoTrex acquired all of the outstanding
    capital stock of Bennett for $42,865,000 in cash. On October 2, 1995,
    ThermoTrex transferred to the Company all of the outstanding capital
    stock of Bennett in exchange for a $42,000,000 principal amount 4.2%
    subordinated convertible note, due 2000, convertible into shares of the
    Company's common stock at $11.79 per share. As of September 27, 1997,
    ThermoTrex had converted $34,000,000 principal amount of this note.

                   Notes to Consolidated Financial Statements

    8.  Significant Customers and Export Sales

        Sales to one customer accounted for 17% and 11% of the Company's
    total revenues in fiscal 1997 and 1996, respectively, and sales to
    another customer accounted for 18% of the Company's total revenues in
    fiscal 1995. Export sales to Germany accounted for 1%, 7%, and 11%, of
    the Company's total revenues in fiscal 1997, 1996, and 1995,
    respectively. Other export sales accounted for 16%, 15%, and 10% of the
    Company's total revenues in fiscal 1997, 1996, and 1995, respectively. In
    general, export sales are denominated in U.S. dollars.

    9.  Contingencies

        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 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 2 for a discussion of certain litigation.
        Due to the inherent uncertainty of dispute resolution, management
    cannot predict the outcome of these matters. While an unfavorable outcome
    of one or both of these matters could have a material adverse effect on
    the Company's results of operations, management does not believe that it
    is reasonably likely that any resolution would have a material adverse
    effect on the Company's financial position.

    10. Fair Value of Financial Instruments

        The Company's financial instruments consist primarily of cash and
    cash equivalents, accounts receivable, accounts payable, due to
    affiliated companies, and its 4.2% subordinated convertible note, due to
    parent company. The carrying amounts of the Company's cash and cash
    equivalents, accounts receivable, accounts payable, and due to affiliated
    companies approximate fair value due to their short-term nature. The fair
    value of the Company's $8,000,000 principal amount 4.2% subordinated
    convertible note (Note 7), determined based on quoted market prices, was
    $11,605,000 at September 27, 1997, and exceeds the carrying amount
    primarily due to the market price of the Company's common stock exceeding
    the conversion price of the convertible note at year end.

                    Report of Independent Public Accountants

    To the Shareholders and Board of Directors of Trex Medical Corporation:

        We have audited the accompanying consolidated balance sheet of Trex
    Medical Corporation (a Delaware corporation and 79%-owned subsidiary of
    ThermoTrex Corporation) and subsidiaries as of September 27, 1997, and
    September 28, 1996, and the related consolidated statements of income,
    shareholders' investment and cash flows for the years ended September 27,
    1997, and September 28, 1996, and the nine months ended September 30,
    1995. 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
    Trex Medical Corporation and subsidiaries as of September 27, 1997, and
    September 28, 1996, and the results of their operations and their cash
    flows for the years ended September 27, 1997, and September 28, 1996, and
    the nine months ended September 30, 1995, 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.
    For this purpose, any statements contained herein that are not statements
    of historical fact may be deemed to be forward-looking statements.
    Without limiting the foregoing, the words "believes," "anticipates,"
    "plans," "expects," "seeks," "estimates," and similar expressions are
    intended to identify forward-looking statements. There are a number of
    important factors that could cause the results of the Company to differ
    materially from those indicated by such forward-looking statements,
    including those detailed immediately after this Management's Discussion
    and Analysis of Financial Condition and Results of Operation under the
    heading "Forward-looking Statements."

    Overview

        The Company designs, manufactures, and markets mammography equipment
    and minimally invasive digital breast-biopsy systems, general-purpose
    X-ray equipment, and specialized X-ray equipment, including imaging
    systems used during diagnostic and interventional vascular and cardiac
    procedures such as balloon angioplasty. The Company sells its systems
    worldwide principally through a network of independent dealers. In
    addition, the Company manufactures breast-biopsy and X-ray systems as an
    original equipment manufacturer (OEM) for other medical equipment
    companies such as United States Surgical Corporation (U.S. Surgical) and
    General Electric Company (GE). The Company has four operating units:
    Lorad, a manufacturer of mammography and digital breast-biopsy systems;
    Bennett X-Ray Corporation (Bennett), a manufacturer of general-purpose
    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.
        The Company conducts all of its manufacturing operations in the
    United States and sells its products worldwide. The Company anticipates
    that an increasing percentage of its revenues will be from export sales.
    The Company's export sales are denominated in U.S. dollars; however, the
    Company's financial performance and competitive position can be affected
    by currency exchange rate fluctuations affecting the relationship between
    the U.S. dollar and foreign currencies.

    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).

    Trex Medical Corporation                        1997 Financial Statements

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

    Fiscal 1997 Compared With Fiscal 1996
        Revenues increased 53% to $229.3 million in fiscal 1997 from
    $150.2 million in fiscal 1996. Revenues increased $56.2 million due to
    the acquisitions of XRE in May 1996 and Continental in September 1996.
    Revenues at Lorad increased 20% in fiscal 1997 from fiscal 1996 as a
    result of increased sales of higher-priced mammography systems, increased
    demand for biopsy systems, and increased sales of lasers to ThermoLase
    Corporation (ThermoLase), a majority-owned subsidiary of ThermoTrex
    Corporation (ThermoTrex), offset in part by a decline in demand for
    nondestructive testing (NDT) systems.
        The gross profit margin declined to 39% in fiscal 1997 from 42% in
    fiscal 1996, primarily due to sales of certain recently introduced
    products that incurred high start-up production costs, the inclusion of
    lower-margin revenues at Continental, and the mix of products sold at
    Bennett.
        Excluding the cost of revenues, total operating expenses as a
    percentage of revenues declined to 28% in fiscal 1997 from 31% in fiscal
    1996. Selling, general, and administrative expenses as a percentage of
    revenues were unchanged at 18% in fiscal 1997 and fiscal 1996. Research
    and development expenses increased $5.8 million to $24.7 million in
    fiscal 1997 from $18.9 million in fiscal 1996. Research and development
    expenses increased $5.6 million due to the acquisitions of XRE and
    Continental and also reflect the Company's continued efforts to develop
    and commercialize new products including the full-field digital
    mammography system and direct-detection X-ray sensor, as well as
    enhancements of existing systems. Under a license agreement between the
    Company and ThermoTrex, the Company may elect to expend approximately
    $2.2 million during fiscal 1998 for additional research and development
    and to expand the field of use in which it is entitled to use
    ThermoTrex's direct-detection digital-imaging technology (Note 7).
        Interest income increased to $1.9 million in fiscal 1997 from
    $1.3 million in fiscal 1996, primarily due to interest income earned on
    the invested proceeds from the Company's initial public offering in
    July 1996, net of cash paid for the September 1996 acquisition of
    Continental. Interest expense, related party, decreased to $0.3 million
    in fiscal 1997 from $1.4 million in fiscal 1996 as a result of the
    conversion by ThermoTrex of $34.0 million principal amount of the
    Company's 4.2% subordinated convertible note, primarily in the fourth
    quarter of fiscal 1996.
        The effective tax rate was 47% in fiscal 1997 and fiscal 1996. The
    effective tax rates exceed the statutory federal income tax rate  
    primarily due to the impact of state income taxes and nondeductible
    amortization of cost in excess of net assets of acquired companies.
        The Company is a defendant in certain patent litigation (Note 2) and
    has been notified that it allegedly infringes certain other technology
    owned by a third party (Note 9). Although an unsuccessful resolution of
    one or both of these matters could have a material adverse effect on the
    Company's results of operations, management does not believe that it is
    reasonably likely that any resolution would have a material adverse
    effect on the Company's financial position.

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

    Fiscal 1996 Compared With 1995
        Revenues increased 113% to $150.2 million in fiscal 1996 from
    $70.5 million in 1995. Revenues increased $56.2 million due to the
    acquisitions of Bennett, XRE, and Continental. Revenues at Lorad
    increased 35% in fiscal 1996 as a result of increased demand for
    mammography systems, NDT systems, and lasers sold to ThermoLase. 
        The gross profit margin declined to 42% in fiscal 1996 from 48% in
    1995, primarily due to the inclusion of lower-margin revenues at Bennett
    and XRE.
        Excluding the cost of revenues, total operating expenses as a
    percentage of revenues declined to 31% in fiscal 1996 from 39% in 1995.
    Selling, general, and administrative expenses as a percentage of revenues
    decreased to 18% in fiscal 1996 from 22% 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. Research and development expenses increased to $18.9 million in
    fiscal 1996 from $11.9 million in 1995, due to the inclusion of
    $4.2 million of expense at Bennett and XRE and the Company's continued
    efforts to develop and commercialize new products including the Company's
    M-IV mammography system (first shipped in the fourth quarter of fiscal
    1996), full-field digital mammography system, and direct-detection X-ray
    sensor, as well as enhancements of existing systems.
        Interest income in fiscal 1996 primarily represents interest income
    earned on the invested proceeds from the Company's private placements of
    common stock in November 1995 and January 1996, and initial public
    offering in July 1996. Interest expense, related party, in fiscal 1996
    represents interest associated with the $42.0 million principal amount
    4.2% subordinated convertible note issued to ThermoTrex.
        The effective tax rate was 47% in fiscal 1996, compared with 46% in
    1995. The effective tax rates exceed the statutory federal income tax
    rate primarily due to the impact of state income taxes and nondeductible
    amortization of cost in excess of net assets of acquired companies.

    Liquidity and Capital Resources

        Consolidated working capital was $79.6 million at September 27, 1997,
    compared with $59.8 million at September 28, 1996. Included in working
    capital are cash and cash equivalents of $36.5 million at September 27,
    1997, and $34.0 million at September 28, 1996. Net cash provided by
    operating activities was $3.9 million in 1997. The Company funded a
    $15.8 million increase in accounts receivable, primarily due to increased
    sales in fiscal 1997 compared with fiscal 1996 and, to a lesser extent,
    due to longer customer payment patterns. The Company expects to improve
    cash flow by increasing adherence to the Company's commercial terms in
    fiscal 1998. The Company funded a $10.3 million increase in inventories
    to support the Company's increased sales and new product introductions at
    Lorad and Bennett.

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

    Liquidity and Capital Resources (continued)

        The Company expended $5.5 million on purchases of property, plant,
    and equipment during fiscal 1997. The Company expects to expend
    approximately $7.0 million for purchases of property, plant, and
    equipment during fiscal 1998.
        In October 1997, the Company acquired substantially all of the
    assets, subject to certain liabilities, of Digitec Corporation, a North
    Carolina-based manufacturer of physiological-monitoring equipment and
    digital-image archiving and networking systems used in cardiac
    catheterization procedures, for approximately $7.2 million in cash,
    subject to a post-closing adjustment.
        In December 1996, the Company sold 300,000 shares of its common stock
    for net proceeds of $4.1 million.
        Although the Company expects to have positive cash flow from its
    existing operations, the Company may require significant amounts of cash
    for any acquisition of a business or technology. The Company expects that
    it will finance any such acquisitions through a combination of internal
    funds, additional debt or equity financing, and/or short-term borrowings
    from ThermoTrex or Thermo Electron Corporation, although it has no
    agreement with these companies to ensure that funds will be available on
    acceptable terms or at all. The Company believes its existing resources
    are sufficient to meet the capital requirements of its existing
    operations 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 1998 and beyond to
    differ materially from those expressed in any forward-looking statements
    made by, or on behalf of, the Company.

        Technological Change and New Products. The market for the Company's
    products is characterized by rapid and significant technological change,
    evolving industry standards and new product introductions. Many of the
    Company's products are technologically innovative, and require
    significant planning, design, development, and testing at the
    technological, product, and manufacturing process levels. These
    activities require significant capital commitments and investment by the
    Company. The high cost of technological innovation is matched by the
    rapid and significant change in the technologies governing the products
    that are competitive in the Company's market, by industry standards that
    may change on short notice, and by the introduction of new products and
    technologies such as magnetic resonance imaging and ultrasound, which may
    render existing products and technologies uncompetitive or obsolete.
    There can be no assurance that the Company's products or proprietary
    technologies will not become uncompetitive or obsolete.

        Dependence on Patents and Proprietary Rights. 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
    the development and regulatory approval process and to the marketplace.
    The Company's success depends in part on whether it can develop
    patentable products and obtain and enforce patent protection for its
    products both in the United States and in other countries. The Company
    has filed, and intends to file, applications as appropriate for patents
    covering both its products and manufacturing processes. No assurance can
    be given that patents will issue from any pending or future patent
    applications owned by, or licensed to, the Company, or that the claims
    allowed under any issued patents will be sufficiently broad to protect
    the Company's technology. In addition, no assurance can be given that any
    issued patents owned by, or licensed to, the Company will not be
    challenged, invalidated, or circumvented, or that the rights granted
    thereunder will provide competitive advantages to the Company. The
    Company could incur substantial costs in defending itself in suits
    brought against it or in suits in which the Company may assert its patent
    rights against others. If the outcome of any such litigation is
    unfavorable to the Company, the Company's business and results of
    operations could be materially adversely affected.
        The Company relies on trade secrets and proprietary know-how that it
    seeks to protect, in part, by confidentiality agreements with its
    collaborators, employees, and consultants. There can be no assurance that
    these agreements will not be breached, that the Company would have

                           Forward-looking Statements

    adequate remedies for any breach, or that the Company's trade secrets
    will not otherwise become known or be independently developed by
    competitors.

        Risks Associated With Pending and Threatened Patent Litigation. In
    April 1992, Fischer Imaging Corporation (Fischer) commenced a lawsuit in
    the United States District Court, District of Colorado, against the
    Company's Lorad division, alleging that Lorad's prone breast-biopsy
    system infringes a Fischer patent on a precision mammographic
    needle-biopsy system. As of September 27, 1997, the Company had
    recognized aggregate revenues of approximately $107.1 million from sales
    of such systems, of which $34.4 million represents sales prior to October
    16, 1995. 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 whether the Company will be subject to such damages or, if
    so, the amount of damages that the Company may be required to pay.
        In connection with the organization of the Company, ThermoTrex
    Corporation, the Company's parent, agreed to indemnify the Company for
    any and all cash damages in connection with the Fischer lawsuit with
    respect to sales of the Company's products occurring prior to October 16,
    1995, when Lorad was transferred to the Company. Notwithstanding this
    indemnification, the Company would be required to report as an expense
    the full amount, including any reimbursable amount, of any damages in
    excess of the amount accrued as of September 27, 1997 (approximately $2
    million), with any indemnification payment it receives from ThermoTrex
    being treated as a contribution to shareholders' investment.
        The Company is also aware of two U.S. patents owned by a former
    employee that have been asserted against the Company relating to its
    high-transmission cellular (HTC)(TM) grid used with its mammography
    systems. If the former employee were successful in enforcing such
    patents, the Company could be subject to damages and enjoined from
    manufacturing and selling the HTC grid.
        The unfavorable outcome of any one or both of the above described
    matters could have a material adverse effect on the Company's business
    and results of operations. The Company's competitors and other parties
    hold other various patents and patent applications in the fields in which
    the Company operates. There can be no assurance that the Company will not
    be found to have infringed third-party patents and, in the event of such
    infringement, the Company could be required to alter its products or
    processes, pay licensing fees, or cease making and selling any infringing
    products and pay damages for past infringement.

                           Forward-looking Statements

        No Assurance of Development and Commercialization of Products Under
    Development. A number of the Company's potential products are currently
    under development. There are a number of technological challenges that
    the Company must successfully address to complete any of its development
    efforts. Product development involves a high degree of risk, and returns
    to investors are dependent upon successful development and
    commercialization of such products. Proposed products based on the
    Company's technologies will require significant additional research and
    development. There can be no assurance that any of the products currently
    being developed by the Company, or those to be developed in the future by
    the Company, will be technologically feasible or accepted by the
    marketplace, or that any such development will be completed in any
    particular time frame.

        Risks Associated with Acquisition Strategy. The Company's strategy
    includes the acquisition of businesses and technologies that complement
    or augment the Company's existing product lines. For example, in October
    1995, the Company acquired its Bennett subsidiary; in May 1996, the
    Company acquired substantially all of the assets and liabilities of XRE,
    a manufacturer of X-ray imaging systems used in the diagnosis and
    treatment of coronary artery disease and other vascular conditions; in
    September 1996, the Company acquired substantially all of the assets and
    liabilities of Continental, a manufacturer of general-purpose and
    specialized X-ray systems; and, in October 1997, the Company acquired
    substantially all of the assets, subject to certain liabilities, of
    Digitec Corporation, a manufacturer of physiological-monitoring equipment
    and digital-image archiving and networking systems used in cardiac
    catheterization procedures. 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. 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 that are not favorable to the
    Company and, in the case of equity financing, may result in dilution to
    the Company's stockholders.

        Intense Competition. The Company encounters and expects to continue
    to encounter intense competition in the sale of its products. The Company
    believes that the principal competitive factors affecting the market for
    its products include product features, product performance and
    reputation, price, and service. The Company's competitors include large
    multinational corporations and their operating units, including GE, the
    Philips Medical Systems North America Company subsidiary of Philips N.V.
    (Philips), the Siemens Corporation subsidiary of Siemens AG (Siemens),
    Toshiba American Medical Systems, Inc., Toshiba America MRI, Inc.,
    Shimadzu, and Picker International, Inc. These companies and certain of
    the Company's other competitors have substantially greater financial,
    marketing, and other resources than the Company. As a result, they may be
    able to adapt more quickly to new or emerging technologies and changes in

                                       30PAGE
<PAGE>
    Trex Medical Corporation                        1997 Financial Statements

                           Forward-looking Statements

    customer requirements, or to devote greater resources to the promotion
    and sale of their products than the Company. Moreover, a significant
    portion of the Company's sales are to U.S. Surgical and GE through OEM
    arrangements. The products sold by such OEM customers compete with
    products offered by the Company directly and through its independent
    dealers. Competition could increase if new companies enter the market or
    if existing competitors expand their product lines or intensify efforts
    within existing product lines. 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.

        Government Regulation, No Assurance of Regulatory Approval. The
    Company's products are subject to regulation by the U.S. Food and Drug
    Administration (the FDA) and equivalent agencies in foreign countries.
    Failure to comply with applicable regulatory requirements can result in,
    among other things, civil and criminal fines, suspensions of approvals,
    recalls or seizures of products, injunctions, and criminal prosecutions.
        To date, all of the Company's products have been classified by the
    FDA as Class II medical devices and have been eligible for FDA marketing
    clearance pursuant to the FDA's 510(k) premarket notification process,
    which is generally shorter than the more involved premarket approval
    (PMA) process. The Company believes that most of its currently
    anticipated future products and substantial modifications to existing
    products will be eligible for the 510(k) premarket notification process.
    However, the FDA has not yet classified full-field digital mammography
    systems such as the one being developed by the Company. While not
    classifying such systems, the FDA has issued a final guidance document
    relating to the protocol for marketing clearance of full-field digital
    mammography systems. This document suggests that clearance may be
    obtained through an enhanced 510(k) application with more extensive
    clinical trials. The protocol set forth in the final guidance document
    calls for clinical trials on 520 subjects prior to applying to the FDA
    for clearance to commercially market such a system. Accordingly, in
    December 1997, the Company submitted a 510(k) application with clinical
    data for its full-field digital mammography system. There can be no
    assurance that full-field digital mammography systems will not be
    classified by the FDA as Class III medical devices subject to the PMA
    process. If such systems are classified as Class III devices, the Company
    would be required to file for FDA marketing approval for its full-field
    digital mammography system under the PMA process or the Product
    Development Protocol (PDP), which would likely require substantial
    additional clinical trials before being accepted by the FDA, if at all.
    Regardless of whether a 510(k), a PMA, or a PDP is finally accepted by
    the FDA, there can be no assurance that the product will receive
    marketing clearance or approval. In addition, full-field digital
    mammography systems will be subject to alternate quality assurance
    standards under the Mammography Quality Standards Act. These alternate
    standards will be submitted by the Company to the FDA for review. The
    Company can make no prediction as to when the FDA will approve such
    standards, if at all. In addition, there can be no assurance that the

                                       31PAGE
<PAGE>
    Trex Medical Corporation                        1997 Financial Statements

                           Forward-looking Statements

    necessary clearances for any of the Company's products will be obtained
    on a timely basis, if at all. 
        FDA regulations also require manufacturers of medical devices to
    adhere to current good manufacturing practices as set forth in the
    quality system regulation (QSR), which include testing, quality control,
    and documentation procedures. The Company's manufacturing facilities are
    subject to periodic inspection by the FDA. No assurances can be given
    that the FDA will not in the future find the Company to be in violation
    of the QSRs.

        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 the Company 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.
    Cost-containment policies may have the effect of reducing reimbursement
    for certain procedures, and as a result may inhibit or reduce demand by
    healthcare providers for products in the markets in which the Company
    competes. While the Company cannot predict what effect the policies of
    government entities and other third party payors will have on future
    sales of the Company's products, there can be no assurance that such
    policies would not have an adverse impact on the operations of the
    Company.

        Dependence Upon Significant OEM Relationships. A significant portion
    of the Company's sales are to U.S. Surgical and GE through OEM
    arrangements. The Company'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 the Company will be able to maintain its
    existing, or establish new, OEM relationships.

        Potential Product Liability. The Company's business exposes it to
    potential product liability claims, which are inherent in the
    manufacturing, marketing, and sale of medical devices, and as such the
    Company may face substantial liability to patients for damages resulting
    from the faulty design or manufacture of products. The Company currently
    maintains product-liability insurance, but there can be no assurance that
    this insurance will provide sufficient coverage in the event of a claim,
    that the Company will be able to maintain such coverage on acceptable
    terms, if at all, or that a product-liability claim would not materially
    adversely affect the business or financial condition of the Company.

                           Forward-looking Statements

        Risks Associated With International Operations. International sales
    accounted for 17%, 22%, and 21% of the Company's revenues in fiscal 1997,
    1996, and 1995, respectively. The Company intends to continue to expand
    its presence in international markets. International revenues are subject
    to a number of risks, including the following: agreements may be
    difficult to enforce and receivables difficult to collect through a
    foreign country's legal system; foreign customers may have longer payment
    cycles; foreign countries may impose additional withholding taxes or
    otherwise tax the Company's foreign income, impose tariffs or adopt other
    restrictions on foreign trade; U.S. export licenses may be difficult to
    obtain; and the protection of intellectual property in foreign countries
    may be more difficult to enforce.
