    Item 1.  Business
             --------

    (a) General Development of Business
        -------------------------------

        Thermedics Detection Inc. (the Company or the Registrant) was
    established as a subsidiary of Thermedics Inc. to develop, manufacture,
    and market high-speed detection and measurement systems used in on-line
    industrial process applications, security applications, and laboratory
    analysis. The Company's industrial process systems use ultratrace
    chemical detectors, high-speed gas chromatography, X-ray imaging,
    near-infrared spectroscopy, and other technologies for quality assurance
    of in-process and finished products, primarily in the food, beverage,
    pharmaceutical, forest products, chemical, and other consumer products
    industries. The Company's security instruments use simultaneous trace
    particle- and vapor-detection techniques based on its proprietary
    chemiluminescence and high-speed gas chromatography technologies.
    Customers use the Company's security instruments to detect plastic and
    other explosives at airports and border crossings, for other
    high-security screening applications, and for forensics and search
    applications.

        Historically, the Company's principal product lines were process
    detection systems, including Alexus(R) systems used to assure the quality
    of refillable plastic containers, and EGIS(R) explosives detectors. The
    Company expanded its product lines to include moisture analysis equipment
    through its acquisition of Moisture Systems Corporation and Rutter & Co.
    B.V. (collectively, Moisture Systems) in January 1996, and also
    introduced its InScan(TM) high-speed X-ray imaging systems (InScan
    systems) and Flash-GC(TM) gas chromatography systems (Flash-GC systems)
    in 1996. The Company has also recently introduced Rampart(TM), the latest
    portable trace-detection system, which incorporates the advanced Flash-GC
    technology in tandem with a highly sensitive chemiluminescence detector.
    In addition, the Company performs contract research and development
    services for government and industry customers and earns service revenues
    through long-term contracts.

        In March and November 1996, the Company issued a total of 683,500
    shares of its common stock in private placements for net proceeds of $7.0
    million. In March 1997, the Company sold 2,671,292 shares of common stock
    in an initial public offering for net proceeds of $28.1 million.

        The Company operated as a division of Thermedics until its
    incorporation as a Massachusetts corporation in December 1990. In
    connection with the Company's incorporation, Thermedics transferred to
    the Company its TEA Analyzer and certain other trace detection
    technologies in exchange for 10,000,000 shares of the Company's common
    stock. A publicly traded subsidiary of Thermo Electron, Thermedics
    develops, manufactures, and markets precision-weighing and inspection
    equipment, electrochemistry and microweighing products, product quality
    assurance systems, a range of power electronics and electronic test
    instruments, and security instruments, as well as implantable
                                        2PAGE
<PAGE>
    heart-assist systems, whole-blood coagulation-testing equipment,
    skin-incision devices, and other biomedical products. As of January 3,
    1998, Thermedics owned 76% of the Company's outstanding common stock. As
    of January 3, 1998, Thermedics is a 58%-owned subsidiary of Thermo
    Electron Corporation. Thermo Electron provides analytical and monitoring
    instruments, biomedical products including heart-assist devices,
    respiratory-care equipment, and mammography systems; paper recycling and
    papermaking equipment; alternative-energy systems; industrial process
    equipment; and other specialized products. Thermo Electron also provides
    industrial outsourcing, particularly in environmental-liability
    management and laboratory analysis, and metallurgical services, and
    conducts advanced-technology research and development. Thermedics and
    Thermo Electron may, from time to time, purchase shares of the Company's
    common stock either on the open market or directly from the Company. See
    Note 3 to Consolidated Financial Statements in the Company's 1997* Annual
    Report to Shareholders for a description of outstanding stock options.

    Forward-looking Statements

    (b) Financial Information About Industry Segments
        ---------------------------------------------

        The Company is engaged in one business segment: the development,
    manufacture, and sale of high-speed detection and measurement systems
    used in on-line industrial process applications, security applications,
    and laboratory analysis. 

    (c) Description of Business
        -----------------------

        (i) Principal Products and Services
            -------------------------------

    Process Detection Systems

        The Company designs, manufactures, and markets high-speed on-line
    trace (parts-per-trillion) measurement, detection, and rejection
    equipment that uses particle- and vapor-detection, and other technologies
    for product quality and productivity applications. 


    * References to 1997, 1996, and 1995 herein are for the fiscal years
      ended January 3, 1998, December 28, 1996, and December 30, 1995,
      respectively.
                                        3PAGE
<PAGE>
        Alexus. The Company's Alexus systems detect trace amounts of
    constituents that affect product quality in refillable plastic soft
    drink, water and other beverage containers. The Company's Alexus systems,
    introduced in 1992, have been installed on almost 300 bottling lines in
    more than 30 countries throughout the world, primarily in Europe and
    Latin America by The Coca-Cola Company, Perrier, and other major beverage
    producers.

        During 1997, 1996, and 1995, the Company derived revenues of $19.2
    million, $14.9 million, and $18.5 million, respectively, from Alexus
    systems.

        InScan. The Company's InScan system uses high-speed X-ray imaging
    technology to determine accurate fill volume, net volume, and package
    integrity of containers for the beverage, food, and other industries.
    InScan uses a low-power X-ray to capture data both vertically and
    horizontally. This data produces an instant, detailed image of each
    container, which InScan's proprietary software automatically compares to
    a predetermined profile used to generate mathematical algorithms to
    determine whether the container is acceptable. InScan incorporates a
    sophisticated, high-speed rejection system that automatically removes
    unacceptable containers from the line. The Company shipped its first
    InScan units in 1996. The Company's InScan systems are currently used by
    major beer and soft drink companies in the U.S. and overseas, including
    Miller, Molson, Coors, Guinness Brewing Company, and The Coca-Cola
    Company. The Company also made its first sales in 1997 to the household
    product industry, through Clorox, and to the cosmetics industry, through
    Estee Lauder. 

        Moisture Systems. The Company's Moisture Systems division, acquired
    in 1996, designs, manufactures, and markets equipment that uses
    near-infrared (NIR) spectroscopy to measure moisture and other product
    constituents, including fats, proteins, oils, flavorings, solvents,
    adhesives, and coatings, in a variety of manufacturing processes. The
    Company's systems are used across the food, pharmaceutical, chemical,
    petrochemical, tobacco, forest products, paper converting, plastics,
    textiles, corrugating, and other industries. In 1997, the Company
    introduced the Quadra Beam 6600T, a system that combines an NIR sensor
    with a processor that displays ingredient information to offer customers
    a less expensive, easy-to-install, and space-saving on-line analyzer. 

        During 1997 and 1996, the Company derived revenues of $15.4 million
    and $18.0 million, respectively, from Moisture Systems.

        Flash-GC Gas Chromatography Systems. The Company designs,
    manufactures, and markets high-speed gas chromatography systems that can
    analyze chemical samples at speeds 20 to 50 times faster than
    conventional gas chromatography. The Company currently markets its
    systems under the trade name "Flash-GC" to analytical services and
    quality laboratories and for near on-line process and quality-control
    applications that require high-speed results. The Company also intends to
    target certain other segments of the conventional gas chromatography
    market in which access to high-speed analysis would be advantageous. The

                                        4PAGE
<PAGE>
    Flash-GC has applications in the food, flavors, fragrance, chemical,
    pharmaceutical, forensics, and automotive industries, as well as in
    medical and environmental laboratories. The Company intends to target
    only those sectors of the laboratory and process gas chromatography
    market that are expected to place a premium on near-instant analysis. The
    Company is continuing to develop the Flash-GC to configure it with
    additional detectors and to introduce a process-oriented version for
    additional on-line applications. 

    Security Instruments

        The Company designs, manufactures, and markets security instruments
    that use trace particle- and vapor-detection techniques for forensics,
    search and screening applications under the direction of police, border
    police, transportation authorities, and carriers. 

        EGIS Systems. The Company's principal security instrument is the EGIS
    system, a highly sensitive particle- and vapor-detection system for
    screening people, baggage, packages, freight, and electronic equipment
    such as personal computers for the presence of a wide range of
    explosives, including plastic explosives that have proven difficult to
    detect using conventional methods. The EGIS system is designed for
    stand-alone use in the detection of explosives in carry-on items and on
    personnel, and can be used in conjunction with enhanced X-ray and other
    advanced imaging systems to provide a comprehensive explosives-detection
    system for checked luggage.

        The Company believes that EGIS is the most accurate and most
    sensitive high-speed trace explosives-detection system available today.
    EGIS utilizes the same high-speed gas chromatography technology used in
    the Flash-GC, combined with chemiluminescent detection techniques to
    detect ultratrace quantities of certain explosives and taggants, and to
    indicate the concentration and type of explosive detected. Because EGIS'
    chemiluminescent detector responds only to compounds of certain
    structures in the sample, rather than to the thousands of compounds that
    may be contained in the sample, EGIS is more selective than competing
    trace-detection systems, with fewer false-positive readings. A processor
    in EGIS compares the chemical profile of the sample to the known profiles
    of various explosives, including TNT, nitroglycerin, PETN, Semtex, and
    C-4. Within seconds of the introduction of the sample into EGIS, the
    system determines whether explosives are present, and, if so, identifies
    the type and amount.

        Initially developed with internal funds and contract funding from the
    Federal Aviation Administration (FAA) and the U.S. Department of State,
    more than 200 EGIS units have been deployed to date. The EGIS system is
    currently operational in 24 countries and is in use in carry-on and
    checked-luggage screening at more than 45 international airports. EGIS is
    also used in government buildings and embassies, and at border crossings
    and other locations where there is a high degree of concern for security.
    The EGIS system has assisted in identifying explosives used in terrorist
    bombings, including those in the Federal Building in Oklahoma City and
    the World Trade Center in New York, as well as in Israel, Buenos Aires,

                                        5PAGE
<PAGE>
    and the United Kingdom. In March 1996, the Company supplied the U.S.
    government with eight EGIS systems to provide counter-terrorism support
    in Israel. Most recently, the Bureau of Alcohol, Tobacco and Firearms and
    the Federal Bureau of Investigation used EGIS systems in their attempt to
    identify the cause of the crash of TWA Flight 800.

        During 1997, 1996, and 1995, the Company derived revenues of $10.3
    million, $7.1 million, and $4.6 million, respectively, from EGIS systems.

        In September 1996, the Company entered into a development contract
    with the FAA to develop EGIS II, a lower-cost EGIS unit for use in more
    portable applications such as remote security checkpoints and
    counter-terrorism activities. In November 1996, the Company introduced
    its new SecurScan, a prototype of a walk-through trace detector designed
    to screen 10 passengers per minute, and introduced its Rampart system, a
    lower-cost unit for airport applications, in 1997. In addition, in 1997,
    the Company entered into a development contract with the British Ministry
    of Defense (MOD) to develop an explosive-detection system that is even
    more sensitive than the EGIS system.

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

        The Company maintains active programs for the development and
    introduction of new products and improvements to existing products. The
    Company also seeks to develop new applications for its existing products
    and technology. The Company is currently devoting significant resources
    toward the enhancement of its existing products and the development of
    new products and technologies, including: enhancing InScan with a wider
    and higher tunnel, which will allow larger containers to be examined, and
    make possible the detection of foreign objects and, in some applications,
    product defects in packaged goods for the food, consumer products, and
    other industries; developing an advanced generation of moisture-detection
    products to address recently identified customers needs; and enhancing
    the Flash-GC to broaden its applications. The Company also is continuing
    to develop Rampart, a lower-cost unit for use in airport screening of
    carry-on baggage. 

        In addition, the British MOD is sponsoring the MOD Explosion Particle
    Dilution Program. The contract is a sole-source contract presented to the
    Company based upon the well-known performance of the EGIS System. 

        The Company also performs contract engineering and/or development on
    behalf of its customers. Recent contracts have included funding by the
    FAA of the development of the SecurScan walk-through explosives-detection
    system as well as feasibility studies and initial development work for
    EGIS II. The Company believes that its reputation for being able to apply
    its core technologies to solve the problems of its customers provides the
    Company with a significant competitive advantage. 

        Company-funded research and development expenses were $5,051,000,
    $4,688,000, and $2,741,000 in 1997, 1996, and 1995, respectively.
    Contract research and development revenues were $1,376,000, 1,758,000,
    and $3,987,000 in 1997, 1996, and 1995, respectively.
                                        6PAGE
<PAGE>

        (iii) Raw Materials
              -------------

        Supplies purchased by the Company are available either from a number
    of different suppliers or from alternative sources that could be
    developed without a material adverse effect on the Company's business. 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
    by appropriate means, including applying for patents. The Company also
    enters into licensing agreements with other companies in which it grants
    or receives rights to specific patents and technical know-how. The
    Company owns 38 U.S. patents, and has filed applications for four
    additional United States patents. The Company's U.S. patents, more than
    60% of which were issued after 1990, have expiration dates ranging from
    1998 through 2014. The Company also owns corresponding patents, or has
    filed corresponding applications, in a number of jurisdictions throughout
    the world. In addition, the Company has an exclusive, perpetual,
    royalty-free license under ten patents covering the use of near-infrared
    and very near-infrared emitting diodes for on-line spectral measurements.
    The Company owns several patents covering certain aspects of its
    chemiluminescent analysis technology and high-speed gas chromatography
    technology. The Company believes that these patents provide the Company
    with competitive advantages in the markets for certain of its products.
    The Company also considers technical know-how, trade secrets, and
    trademarks to be important to its business. 

        (v) Seasonal Influences
            -------------------

        There are no significant seasonal influences on the Company's sales
    of its products.

        (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
              -------------------------------

        Sales to The Coca-Cola Company accounted for 26%, 24%, and 36% of the
    Company's total revenues in 1997, 1996, and 1995, respectively.

        (viii) Backlog
               -------

        The Company's backlog of firm orders was $6,922,000 and $11,955,000
    as of January 3, 1998 and December 28, 1996, respectively. Certain of
    these orders are cancellable by the customer upon payment of a
    cancellation charge. The Company believes that substantially all of the
    backlog at January 3, 1998, will be shipped or completed during the next

                                        7PAGE
<PAGE>
    twelve months. The Company does not believe that the size of its backlog
    is necessarily indicative of intermediate or long-term trends in its
    business.

        (ix) Government Contracts
             --------------------

        The security instruments manufactured and marketed by the Company for
    use in airports are subject to regulation by the FAA, corresponding
    foreign governmental authorities, The International Civil Aviation
    Organization, and the United Nations organization and are responsible for
    establishing standard practices for the aviation industry on a worldwide
    basis. Sales of the Company's security instruments for use in airports
    have been and will continue to be dependent upon governmental initiatives
    to require or support the screening of baggage, carry-on items, and
    people with advanced explosives-detection equipment. Substantially all of
    such systems have been installed at airports in countries in which the
    applicable government or regulatory authority overseeing the operations
    of the airport has mandated such screening. Such mandates are influenced
    by many factors outside of the control of the Company, including
    political and budgetary concerns of governments, airlines, and airports.
    To date, the FAA has not mandated the use of any explosives-detection
    system.

        (x) Competition
            -----------

        The markets for the Company's products are highly competitive.
    Competitors may develop superior products or products of similar quality
    for sale at the same or lower prices. Moreover, there can be no assurance
    that the Company's products will not be rendered obsolete by new industry
    standards or changing technology. There can be no assurance that the
    Company will be able to compete successfully with existing or new
    competitors. The Company employs a variety of sales methods for its
    products and services that are designed to fit the needs of particular
    customer groups. 

    Process Detection Systems

        The Company's product quality assurance systems compete with
    detection systems manufactured by numerous companies. The Company
    believes, however, that these companies are generally focused on
    particular niches in the process detection systems market, only in some
    of which the Company competes. The Alexus system encounters competition
    throughout the world, but primarily in the German-speaking areas of
    Europe, with products offered by Walter Grassle GmbH of Germany and
    Sudtronics S.A. of Switzerland. InScan competes with gamma-based beverage
    fill-height detectors offered by a number of companies, including
    Industrial Dynamics Company, based in California, and Heuft Systemtechnik
    GmbH, based in Germany. Alexus systems are also sold through Krones GmbH,
    a large German turnkey plant contractor for new bottling lines.
    Competition in the moisture-detection market is highly fragmented. The
    Company's principal competitor in this market is Infrared Engineering
    Limited, based in England. The Company sells and services both its InScan
    and moisture systems equipment through a mix of direct sales,

                                        8PAGE
<PAGE>
    manufacturers' representatives, and original equipment manufacturer
    relationships around the world. The Company also operates factory service
    centers for these products. The Flash-GC is a new technology competing in
    the developing high-speed gas chromatography market segment. The
    Company's Flash-GC competes principally against high-speed gas
    chromatographs offered by ChromFast, based in Michigan.  The Company's
    Flash-GC systems are sold through a direct sales and services
    organization. The Company is currently attempting to recruit additional
    direct sales representatives for certain regions of the United States.

        Competition in the markets for each of the Company's process
    detection systems is based primarily on performance, durability, service
    and, to a lesser extent, price. The Company believes that its systems'
    performance and speed, as well as the Company's reputation for developing
    superior new technologies and for the innovative application of existing
    technologies to a variety of high-speed production environments and
    product quality assurance problems, are competitive advantages.

    Security Instruments

        In the security instrument market, the Company competes with a small
    number of companies, including other makers of chemical trace detection
    instruments, and, to a lesser degree, makers of enhanced X-ray detectors.
    Competition in this market is based primarily on performance, including
    speed, accuracy, and the range of explosives that can be detected; ease
    of use; service; and price. The Company's principal competitor in the
    trace detection market is Barringer Technologies Inc., a Canadian firm
    that has placed several trace detectors in airport applications.The
    Company's security instruments are sold to a few key decision-makers
    around the world, primarily government agencies or private companies
    fulfilling government regulations. Accordingly, sales are made by a
    small, specialized direct sales force, supported by a broader service
    organization, from offices shared with Alexus sales and service
    organizations.

        (xii) Environmental Protection Regulations
              ------------------------------------

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

        (xiii) Number of Employees
               -------------------

        As of January 3, 1998, the Company had 218 full-time employees.

    To the Shareholders and Board of Directors of Thermedics Detection Inc.:

        We have audited, in accordance with generally accepted auditing
    standards, the consolidated financial statements included in Thermedics
    Detection Inc.'s Annual Report to Shareholders incorporated by reference
    in this Form 10-K, and have issued our report thereon dated February 12,
    1998. Our audits were made for the purpose of forming an opinion on those
    statements taken as a whole. The schedule listed in Item 14 on page 13 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 consolidated
    financial data required to be set forth therein in relation to the basic
    consolidated financial statements taken as a whole.

              AMENDED AND RESTATED MASTER GUARANTEE REIMBURSEMENT
                               AND LOAN AGREEMENT


             This AGREEMENT is entered into as of the 16th day of
        December, 1997, by and among Thermo Electron Corporation (the
        "Parent") and those of its subsidiaries that join in this
        Agreement by executing the signature page hereto (the "Majority
        Owned Subsidiaries").

                                   WITNESSETH:

             WHEREAS, the Majority Owned Subsidiaries and their
        wholly-owned subsidiaries wish to enter into various financial
        transactions, such as convertible or nonconvertible debt, loans,
        and equity offerings, and other contractual arrangements with
        third parties (the "Underlying Obligations") and may provide
        credit support to, on behalf of or for the benefit of, other
        subsidiaries of the Parent ("Credit Support Obligations"); 

             WHEREAS, the Majority Owned Subsidiaries and the Parent
        acknowledge that the Majority Owned Subsidiaries and their
        wholly-owned subsidiaries may be unable to enter into many kinds
        of Underlying Obligations without a guarantee of their
        performance thereunder from the Parent (a "Parent Guarantee") or
        without obtaining Credit Support Obligations from other Majority
        Owned Subsidiaries;

             WHEREAS, the Majority Owned Subsidiaries and their
        wholly-owned subsidiaries may borrow funds from the Parent, and
        the Parent may loan funds or provide credit to the Majority Owned
        Subsidiaries and their wholly-owned subsidiaries, on a short-term
        and unsecured basis;

             WHEREAS, certain Majority Owned Subsidiaries ("Second Tier
        Majority Owned Subsidiaries ") may themselves be majority owned
        subsidiaries of other Majority Owned Subsidiaries ("First Tier
        Majority Owned Subsidiaries");

             WHEREAS, for various reasons, Parent Guarantees of a Second
        Tier Majority Owned Subsidiary's Underlying Obligations may be
        demanded and given without the respective First Tier Majority
        Owned Subsidiary also issuing a guarantee of such Underlying
        Obligation; 

             WHEREAS, the Parent may itself make a loan or provide other
        credit to a Second Tier Majority Owned Subsidiary or its
        wholly-owned subsidiaries under circumstances where the
        applicable First Tier Majority Owned Subsidiary does not provide
        such credit; and

             WHEREAS, the Parent is willing to consider continuing to
        issue Parent Guarantees and providing credit, and the Majority
        Owned Subsidiaries are willing to consider continuing to provide
PAGE
<PAGE>
        Credit Support Obligations and to borrow funds, on the terms and
        conditions set forth below;

             NOW, THEREFORE, in consideration of the foregoing and other
        good and valuable consideration, the receipt and sufficiency of
        which are hereby acknowledged by each party hereto, the parties
        agree as follows:

        1.   If the Parent provides a Parent Guarantee of an Underlying
             Obligation, and the beneficiary(ies) of the Parent Guarantee
             enforce the Parent Guarantee, or the Parent performs under
             the Parent Guarantee for any other reason, then the Majority
             Owned Subsidiary that is obligated, either directly or
             indirectly through a wholly-owned subsidiary, under such
             Underlying Obligation shall indemnify and save harmless the
             Parent from any liability, cost, expense or damage
             (including reasonable attorneys' fees) suffered by the
             Parent as a result of the Parent Guarantee.  If the
             Underlying Obligation is issued by a Second Tier Majority
             Owned Subsidiary or a wholly-owned subsidiary thereof, and
             such Second Tier Majority Owned Subsidiary is unable to
             fully indemnify the Parent (because of the poor financial
             condition of such Second Tier Majority Owned Subsidiary, or
             for any other reason), then the First Tier Majority Owned
             Subsidiary that owns the majority of the stock of such
             Second Tier Majority Owned Subsidiary shall indemnify and
             save harmless the Parent from any remaining liability, cost,
             expense or damage (including reasonable attorneys' fees)
             suffered by the Parent as a result of the Parent Guarantee.
             If a Majority Owned Subsidiary or a wholly-owned subsidiary
             thereof provides a Credit Support Obligation for any
             subsidiary of the Parent, other than a subsidiary of such
             Majority Owned Subsidiary, and the beneficiary(ies) of the
             Credit Support Obligation enforce the Credit Support
             Obligation, or the Majority Owned Subsidiary or its
             wholly-owned subsidiary  performs under the Credit Support
             Obligation for any other reason, then the Parent shall
             indemnify and save harmless the Majority Owned Subsidiary or
             its wholly-owned subsidiary, as applicable, from any
             liability, cost, expense or damage (including reasonable
             attorneys' fees) suffered by the Majority Owned Subsidiary
             or its wholly-owned subsidiary, as applicable, as a result
             of the Credit Support Obligation.  Without limiting the
             foregoing, Credit Support Obligations include the deposit of
             funds by a Majority Owned Subsidiary or a wholly-owned
             subsidiary thereof in a credit arrangement with a banking
             facility whereby such funds are available to the banking
             facility as collateral for overdraft obligations of other
             Majority Owned Subsidiaries or their subsidiaries also
             participating in the credit arrangement with such banking
             facility.

        2.   For purposes of this Agreement, the term "guarantee" shall
             include not only a formal guarantee of an obligation, but
PAGE
<PAGE>
             also any other arrangement where the Parent is liable for
             the obligations of a Majority Owned Subsidiary or its
             wholly-owned subsidiaries.  Such other arrangements include
             (a) representations, warranties and/or covenants or other
             obligations joined in by the Parent, whether on a joint or
             joint and several basis, for the benefit of the Majority
             Owned Subsidiary or its wholly-owned subsidiaries and (b)
             responsibility of the Parent by operation of law for the
             acts and omissions of the Majority Owned Subsidiary or its
             wholly-owned subsidiaries, including controlling person
             liability under securities and other laws.

        3.   Promptly after the Parent receives notice that a beneficiary
             of a Parent Guarantee is seeking to enforce such Parent
             Guarantee, the Parent shall notify the Majority Owned
             Subsidiary(s) obligated, either directly or indirectly
             through a wholly-owned subsidiary, under the relevant
             Underlying Obligation.  Such Majority Owned Subsidiary(s) or
             wholly-owned subsidiary thereof, as applicable, shall have
             the right, at its own expense, to contest the claim of such
             beneficiary.  If a Majority Owned Subsidiary or wholly-owned
             subsidiary thereof, as applicable, is contesting the claim
             of such beneficiary, the Parent will not perform under the
             relevant Parent Guarantee unless and until, in the Parent's
             reasonable judgment, the Parent is obligated under the terms
             of such Parent Guarantee to perform.  Subject to the
             foregoing, any dispute between a Majority Owned Subsidiary
             or wholly-owned subsidiary thereof, as applicable, and a
             beneficiary of a Parent Guarantee shall not affect such
             Majority Owned Subsidiary's obligation to promptly indemnify
             the Parent hereunder.  Promptly after a Majority Owned
             Subsidiary or wholly-owned subsidiary thereof, as
             applicable, receives notice that a beneficiary of a Credit
             Support Obligation is seeking to enforce such Credit Support
             Obligation, the Majority Owned Subsidiary shall notify the
             Parent.  The Parent shall have the right, at its own
             expense, to contest the claim of such beneficiary.  If the
             Parent or the subsidiary of the Parent on whose behalf the
             Credit Support Obligation is given is contesting the claim
             of such beneficiary, the Majority Owned Subsidiary or
             wholly-owned subsidiary thereof, as applicable, will not
             perform under the relevant Credit Support Obligation unless
             and until, in the Majority Owned Subsidiary's reasonable
             judgment, the Majority Owned Subsidiary or wholly-owned
             subsidiary thereof, as applicable, is obligated under the
             terms of such Credit Support Obligation to perform.  Subject
             to the foregoing, any dispute between the Parent or the
             subsidiary of the Parent on whose behalf the Credit Support
             Obligation was given, on the one hand, and a beneficiary of
             a Credit Support Obligation, on the other, shall not affect
             the Parent's obligation to promptly indemnify the Majority
             Owned Subsidiary or its wholly-owned subsidiary, as
             applicable, hereunder.
PAGE
<PAGE>
        4.   Upon the request of a Majority Owned Subsidiary, the Parent
             may make loans and advances to the Majority Owned Subsidiary
             or its wholly-owned subsidiaries on a short-term, revolving
             credit basis, from time to time in such amounts as mutually
             determined by the Parent and the Majority Owned Subsidiary.
             The aggregate principal amount of such loans and advances
             shall be reflected on the books and records of the Majority
             Owned Subsidiary (or wholly-owned subsidiary, as applicable)
             and the Parent.  All such loans and advances shall be on an
             unsecured basis unless specifically provided otherwise in
             loan documents executed at that time.  The Majority Owned
             Subsidiary or its wholly-owned subsidiaries, as applicable,
             shall pay interest on the aggregate unpaid principal amount
             of such loans from time to time outstanding at a rate
             ("Interest Rate") equal to the rate of the Commercial Paper
             Composite Rate for 90-day maturities as reported by Merrill
             Lynch Capital Markets, as an average of the last five
             business days of such Majority Owned Subsidiary's latest
             fiscal quarter then ended, plus twenty-five (25) basis
             points.  The Interest Rate shall be adjusted on the first
             business day of each fiscal quarter of such Majority Owned
             Subsidiary pursuant to the Interest Rate formula contained
             in the preceding sentence and shall be in effect for the
             entirety of such fiscal quarter.  Interest shall be computed
             on a 360-day basis.  The aggregate principal amount
             outstanding and accrued interest thereon shall be payable on
             demand.  The principal and accrued interest may be paid by
             the Majority Owned Subsidiaries or their wholly-owned
             subsidiaries, as applicable, at any time or from time to
             time, in whole or in part, without premium or penalty.  All
             payments shall be applied first to accrued interest and then
             to principal.  Principal and interest shall be payable in
             lawful money of the United States of America, in immediately
             available funds, at the principal office of the Parent or at
             such other place as the Parent may designate from time to
             time in writing to the Majority Owned Subsidiary.  The
             unpaid principal amount of any such borrowings, and accrued
             interest thereon, shall become immediately due and payable,
             without demand, upon the failure of the Majority Owned
             Subsidiary or its wholly-owned subsidiary, as applicable, to
             pay its debts as they become due, the insolvency of the
             Majority Owned Subsidiary or its wholly-owned subsidiary, as
             applicable, the filing by or against the Majority Owned
             Subsidiary or its wholly-owned subsidiary, as applicable, of
             any petition under the U.S. Bankruptcy Code (or the filing
             of any similar petition under the insolvency law of any
             jurisdiction), or the making by the Majority Owned
             Subsidiary or its wholly-owned subsidiary, as applicable, 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 Majority Owned Subsidiary
             or its wholly-owned subsidiary, as applicable.  In case any
             payments of principal and interest shall not be paid when
PAGE
<PAGE>
             due, the Majority Owned Subsidiary or its wholly-owned
             subsidiary, as applicable, further promises to pay all cost
             of collection, including reasonable attorneys' fees.   

        5.   If the Parent makes a loan or provides other credit ("Credit
             Extension") to a Second Tier Majority Owned Subsidiary, the
             First Tier Majority Owned Subsidiary that owns the majority
             of the stock of such Second Tier Majority Owned Subsidiary
             hereby guarantees the Second Tier Majority Owned
             Subsidiary's obligations to the Parent thereunder.  Such
             guaranty shall be enforced only after the Parent, in its
             reasonable judgment, determines that the Second Tier
             Majority Owned Subsidiary is unable to fully perform its
             obligations under the Credit Extension.  If the Parent
             provides Credit Extension to a wholly-owned subsidiary of a
             Second Tier Majority Owned Subsidiary, the Second Tier
             Majority Owned Subsidiary hereby guarantees it wholly-owned
             subsidiary's obligations to the Parent thereunder and the
             First Tier Majority Owned Subsidiary that owns the majority
             of the stock of such Second Tier Majority Owned Subsidiary
             hereby guarantees the Second Tier Majority Owned
             Subsidiary's obligations to the Parent hereunder.  Such
             guaranty by the First Tier Majority Owned Subsidiary shall
             be enforced only after the Parent, in its reasonable
             judgment, determines that the Second Tier Majority Owned
             Subsidiary is unable to fully perform its guaranty
             obligation hereunder.  

        6.   All payments required to be made by a Majority Owned
             Subsidiary or its wholly-owned subsidiaries, as applicable,
             shall be made within two days after receipt of notice from
             the Parent. All payments required to be made by the Parent
             shall be made within two days after receipt of notice from
             the Majority Owned Subsidiary.  

        7.   This Agreement shall be governed by and construed in
             accordance with the laws of the Commonwealth of
             Massachusetts applicable to contracts made and performed
             therein.

        to be executed by their duly authorized officers as of the date
        first above written.

              AMENDED AND RESTATED MASTER GUARANTEE REIMBURSEMENT
                               AND LOAN AGREEMENT


             This AGREEMENT is entered into as of the 16th day of
        December, 1997, by and among Thermedics Inc. (the "Parent") and
        those of its subsidiaries that join in this Agreement by
        executing the signature page hereto (the "Majority Owned
        Subsidiaries").

                                   WITNESSETH:

             WHEREAS, the Majority Owned Subsidiaries and their
        wholly-owned subsidiaries wish to enter into various financial
        transactions, such as convertible or nonconvertible debt, loans,
        and equity offerings, and other contractual arrangements with
        third parties (the "Underlying Obligations") and may provide
        credit support to, on behalf of or for the benefit of, other
        subsidiaries of the Parent ("Credit Support Obligations"); 

             WHEREAS, the Majority Owned Subsidiaries and the Parent
        acknowledge that the Majority Owned Subsidiaries and their
        wholly-owned subsidiaries may be unable to enter into many kinds
        of Underlying Obligations without a guarantee of their
        performance thereunder from the Parent (a "Parent Guarantee") or
        without obtaining Credit Support Obligations from other Majority
        Owned Subsidiaries;

             WHEREAS, the Majority Owned Subsidiaries and their
        wholly-owned subsidiaries may borrow funds from the Parent, and
        the Parent may loan funds or provide credit to the Majority Owned
        Subsidiaries and their wholly-owned subsidiaries, on a short-term
        and unsecured basis; and

             WHEREAS, the Parent is willing to consider continuing to
        issue Parent Guarantees and providing credit, and the Majority
        Owned Subsidiaries are willing to consider continuing to provide
        Credit Support Obligations and to borrow funds, on the terms and
        conditions set forth below;

             NOW, THEREFORE, in consideration of the foregoing and other
        good and valuable consideration, the receipt and sufficiency of
        which are hereby acknowledged by each party hereto, the parties
        agree as follows:

        1.   If the Parent provides a Parent Guarantee of an Underlying
             Obligation, and the beneficiary(ies) of the Parent Guarantee
             enforce the Parent Guarantee, or the Parent performs under
             the Parent Guarantee for any other reason, then the Majority
             Owned Subsidiary that is obligated, either directly or
             indirectly through a wholly-owned subsidiary, under such
             Underlying Obligation shall indemnify and save harmless the
             Parent from any liability, cost, expense or damage
             (including reasonable attorneys' fees) suffered by the
PAGE
<PAGE>
             Parent as a result of the Parent Guarantee.  If a Majority
             Owned Subsidiary or a wholly-owned subsidiary thereof
             provides a Credit Support Obligation for any subsidiary of
             the Parent, other than a subsidiary of such Majority Owned
             Subsidiary, and the beneficiary(ies) of the Credit Support
             Obligation enforce the Credit Support Obligation, or the
             Majority Owned Subsidiary or its wholly-owned subsidiary  
             performs under the Credit Support Obligation for any other
             reason, then the Parent shall indemnify and save harmless
             the Majority Owned Subsidiary or its wholly-owned
             subsidiary, as applicable, from any liability, cost, expense
             or damage (including reasonable attorneys' fees) suffered by
             the Majority Owned Subsidiary or its wholly-owned
             subsidiary, as applicable, as a result of the Credit Support
             Obligation.  Without limiting the foregoing, Credit Support
             Obligations include the deposit of funds by a Majority Owned
             Subsidiary or a wholly-owned subsidiary thereof in a credit
             arrangement with a banking facility whereby such funds are
             available to the banking facility as collateral for
             overdraft obligations of other Majority Owned Subsidiaries
             or their subsidiaries also participating in the credit
             arrangement with such banking facility.

        2.   For purposes of this Agreement, the term "guarantee" shall
             include not only a formal guarantee of an obligation, but
             also any other arrangement where the Parent is liable for
             the obligations of a Majority Owned Subsidiary or its
             wholly-owned subsidiaries.  Such other arrangements include
             (a) representations, warranties and/or covenants or other
             obligations joined in by the Parent, whether on a joint or
             joint and several basis, for the benefit of the Majority
             Owned Subsidiary or its wholly-owned subsidiaries and (b)
             responsibility of the Parent by operation of law for the
             acts and omissions of the Majority Owned Subsidiary or its
             wholly-owned subsidiaries, including controlling person
             liability under securities and other laws.

        3.   Promptly after the Parent receives notice that a beneficiary
             of a Parent Guarantee is seeking to enforce such Parent
             Guarantee, the Parent shall notify the Majority Owned
             Subsidiary(s) obligated, either directly or indirectly
             through a wholly-owned subsidiary, under the relevant
             Underlying Obligation.  Such Majority Owned Subsidiary(s) or
             wholly-owned subsidiary thereof, as applicable, shall have
             the right, at its own expense, to contest the claim of such
             beneficiary.  If a Majority Owned Subsidiary or wholly-owned
             subsidiary thereof, as applicable, is contesting the claim
             of such beneficiary, the Parent will not perform under the
             relevant Parent Guarantee unless and until, in the Parent's
             reasonable judgment, the Parent is obligated under the terms
             of such Parent Guarantee to perform.  Subject to the
             foregoing, any dispute between a Majority Owned Subsidiary
             or wholly-owned subsidiary thereof, as applicable, and a
             beneficiary of a Parent Guarantee shall not affect such
PAGE
<PAGE>
             Majority Owned Subsidiary's obligation to promptly indemnify
             the Parent hereunder.  Promptly after a Majority Owned
             Subsidiary or wholly-owned subsidiary thereof, as
             applicable, receives notice that a beneficiary of a Credit
             Support Obligation is seeking to enforce such Credit Support
             Obligation, the Majority Owned Subsidiary shall notify the
             Parent.  The Parent shall have the right, at its own
             expense, to contest the claim of such beneficiary.  If the
             Parent or the subsidiary of the Parent on whose behalf the
             Credit Support Obligation is given is contesting the claim
             of such beneficiary, the Majority Owned Subsidiary or
             wholly-owned subsidiary thereof, as applicable, will not
             perform under the relevant Credit Support Obligation unless
             and until, in the Majority Owned Subsidiary's reasonable
             judgment, the Majority Owned Subsidiary or wholly-owned
             subsidiary thereof, as applicable, is obligated under the
             terms of such Credit Support Obligation to perform.  Subject
             to the foregoing, any dispute between the Parent or the
             subsidiary of the Parent on whose behalf the Credit Support
             Obligation was given, on the one hand, and a beneficiary of
             a Credit Support Obligation, on the other, shall not affect
             the Parent's obligation to promptly indemnify the Majority
             Owned Subsidiary or its wholly-owned subsidiary, as
             applicable, hereunder.  

        4.   Upon the request of a Majority Owned Subsidiary, the Parent
             may make loans and advances to the Majority Owned Subsidiary
             or its wholly-owned subsidiaries on a short-term, revolving
             credit basis, from time to time in such amounts as mutually
             determined by the Parent and the Majority Owned Subsidiary.
             The aggregate principal amount of such loans and advances
             shall be reflected on the books and records of the Majority
             Owned Subsidiary (or wholly-owned subsidiary, as applicable)
             and the Parent.  All such loans and advances shall be on an
             unsecured basis unless specifically provided otherwise in
             loan documents executed at that time.  The Majority Owned
             Subsidiary or its wholly-owned subsidiaries, as applicable,
             shall pay interest on the aggregate unpaid principal amount
             of such loans from time to time outstanding at a rate
             ("Interest Rate") equal to the rate of the Commercial Paper
             Composite Rate for 90-day maturities as reported by Merrill
             Lynch Capital Markets, as an average of the last five
             business days of such Majority Owned Subsidiary's latest
             fiscal quarter then ended, plus twenty-five (25) basis
             points.  The Interest Rate shall be adjusted on the first
             business day of each fiscal quarter of such Majority Owned
             Subsidiary pursuant to the Interest Rate formula contained
             in the preceding sentence and shall be in effect for the
             entirety of such fiscal quarter.  Interest shall be computed
             on a 360-day basis.  The aggregate principal amount
             outstanding and accrued interest thereon shall be payable on
             demand.  The principal and accrued interest may be paid by
             the Majority Owned Subsidiaries or their wholly-owned
             subsidiaries, as applicable, at any time or from time to
PAGE
<PAGE>
             time, in whole or in part, without premium or penalty.  All
             payments shall be applied first to accrued interest and then
             to principal.  Principal and interest shall be payable in
             lawful money of the United States of America, in immediately
             available funds, at the principal office of the Parent or at
             such other place as the Parent may designate from time to
             time in writing to the Majority Owned Subsidiary.  The
             unpaid principal amount of any such borrowings, and accrued
             interest thereon, shall become immediately due and payable,
             without demand, upon the failure of the Majority Owned
             Subsidiary or its wholly-owned subsidiary, as applicable, to
             pay its debts as they become due, the insolvency of the
             Majority Owned Subsidiary or its wholly-owned subsidiary, as
             applicable, the filing by or against the Majority Owned
             Subsidiary or its wholly-owned subsidiary, as applicable, of
             any petition under the U.S. Bankruptcy Code (or the filing
             of any similar petition under the insolvency law of any
             jurisdiction), or the making by the Majority Owned
             Subsidiary or its wholly-owned subsidiary, as applicable, 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 Majority Owned Subsidiary
             or its wholly-owned subsidiary, as applicable.  In case any
             payments of principal and interest shall not be paid when
             due, the Majority Owned Subsidiary or its wholly-owned
             subsidiary, as applicable, further promises to pay all cost
             of collection, including reasonable attorneys' fees.   

        5.   All payments required to be made by a Majority Owned
             Subsidiary or its wholly-owned subsidiaries, as applicable,
             shall be made within two days after receipt of notice from
             the Parent. All payments required to be made by the Parent
             shall be made within two days after receipt of notice from
             the Majority Owned Subsidiary.  

        6.   This Agreement shall be governed by and construed in
             accordance with the laws of the Commonwealth of
             Massachusetts applicable to contracts made and performed
             therein.

             IN WITNESS WHEREOF, the parties have caused this Agreement
        to be executed by their duly authorized officers as of the date
        first above written.

                            THERMEDICS DETECTION INC.
                     RESTATED STOCK HOLDING ASSISTANCE PLAN


        SECTION 1.   Purpose.

             The purpose of this Plan is to benefit Thermedics Detection
        Inc. (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:   Thermedics Detection Inc., a Massachusetts
        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 Thermedics Detection Inc. Stock Holding
        Assistance Plan, as amended from time to time.

        SECTION 3.     Administration.

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

        SECTION 4.     Loans and Loan Limits.

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

             Each Loan shall be full recourse and evidenced by a
        non-interest bearing promissory note substantially in the form
        attached hereto as Exhibit A (the "Note") and maturing 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
PAGE
<PAGE>
        the Loan, provided that the Committee may, in its sole and
        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  Thermedics  Detection  Inc.   (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. Any amount  remaining
        unpaid under this Note 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
        enforcement of this Note.  The undersigned hereby assents to  any
        indulgence  and  any  extension  of  time  for  payment  of   any
        indebtedness  evidenced  hereby  granted  or  permitted  by   the
        Company.

        Holding Assistance Plan and shall be governed by and construed in
        accordance  with,  such  Plan  and  the  laws  of  the  State  of

                   Notes to Consolidated Financial Statements

    1.  Nature of Operations and Summary of Significant Accounting Policies

    Nature of Operations
        Thermedics Detection Inc. (the Company) develops, manufactures, and
    markets high-speed detection and measurement systems used in on-line
    industrial process applications, security applications, and laboratory
    analysis. The Company's industrial process systems use ultratrace
    chemical detectors, high-speed gas chromatography, X-ray imaging,
    near-infrared spectroscopy, and other technologies for quality assurance
    of in-process and finished products, primarily in the food, beverage,
    pharmaceutical, forest products, chemical, and other consumer products
    industries. The Company's security instruments use simultaneous trace
    particle- and vapor-detection techniques based on its proprietary
    chemiluminesence and high-speed gas chromatography technologies.
    Customers use the Company's security instruments to detect plastic and
    other explosives at airports and border crossings, for other
    high-security screening applications, and for forensics and search
    applications. 

    Relationship with Thermedics Inc. and Thermo Electron Corporation
        The Company operated as a division of Thermedics Inc. until its
    incorporation as a Massachusetts corporation in December 1990. In
    connection with the Company's incorporation, Thermedics transferred to
    the Company its TEA Analyzer and certain other trace detection
    technologies in exchange for 10,000,000 shares of the Company's common
    stock. As of January 3, 1998, Thermedics owned 10,127,675 shares of the
    Company's outstanding common stock, representing 76% of such stock
    outstanding. As of January 3, 1998, Thermedics is a 58%-owned subsidiary
    of Thermo Electron Corporation.
    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. Certain amounts in fiscal
    1996 have been reclassified to conform to the fiscal 1997 financial
    statement presentation.

    Fiscal Year
        The Company has adopted a fiscal year ending the Saturday nearest
    December 31. References to 1997, 1996, and 1995 are for the fiscal years
    ended January 3, 1998, December 28, 1996, and December 30, 1995,
    respectively. Fiscal year 1997 included 53 weeks; 1996 and 1995 each
    included 52 weeks.

    Revenue Recognition
        The Company recognizes product revenues upon shipment of its
    products. The Company provides a reserve for its estimate of warranty and
    installation costs at the time of shipment. The Company recognizes
    service revenues over the term of the contract. Deferred revenue in the
    accompanying balance sheet consists of unearned revenue on service
    contracts which is recognized over the life of the service contract.
    Revenues and profits on long-term contracts are recognized using the
    percentage-of-completion method. Revenues recorded under the percentage-

    of-completion method, including revenues from long-term research and
    development contracts, were $1,376,000, $1,758,000, and $3,987,000 in
    1997, 1996, and 1995, respectively. The percentage of completion is
    determined by relating the actual costs incurred to date to management's
    estimate of total costs to be incurred on each contract. If a loss is
    indicated on any contract in process, a provision is made currently for
    the entire loss. Contracts generally provide for the billing of customers
    on a cost-plus-fixed-fee basis as costs are incurred. Revenues earned on
    contracts in process in excess of billings are classified as unbilled
    contract costs and fees in the accompanying balance sheet. There are no
    significant amounts included in the accompanying balance sheet that are
    not expected to be recovered from existing contracts at current contract
    values, or that are not expected to be collected within one year,
    including amounts that are billed but not paid under retainage
    provisions. 

    Stock-based Compensation Plans
        The Company applies Accounting Principles Board Opinion No. 25,
    "Accounting for Stock Issued to Employees" (APB 25) and related
    Interpretations in accounting for its stock-based compensation plans
    (Note 3). 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
        In the periods prior to its initial public offering, the Company was
    included in Thermedics' consolidated federal and certain state income tax
    returns. Subsequent to the Company's initial public offering in March
    1997, Thermedics' equity ownership of the Company was reduced below 80%
    and, as a result, the Company is required to file its own federal income
    tax return.
        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
        During the fourth quarter of 1997, the Company adopted SFAS No. 128,
    "Earnings per Share" (Note 9). As a result, all previously reported
    earnings per share have been restated; however, basic and diluted
    earnings per share equals the Company's previously reported earnings per
    share for 1996 and 1995. Basic earnings per share have been computed by
    dividing net income by the weighted average number of shares outstanding
    during the year. Diluted earnings per share have been computed assuming
    the exercise of stock options, as well as their related income tax
    effects.

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

    Stock Split
        In March 1996, the Company declared and effected a two-for-three
    reverse stock split. All share and per share information has been
    restated to reflect the reverse stock split.

    Cash and Cash Equivalents
        At year-end 1997 and 1996, $40,043,000 and $10,976,000, respectively,
    of the Company's cash equivalents were invested in a repurchase agreement
    with Thermo Electron. Under this agreement, the Company in effect lends
    excess cash to Thermo Electron, which Thermo Electron collateralizes with
    investments principally consisting of corporate notes, commercial paper,
    U.S. government-agency securities, 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 and have an original maturity of
    three months or less. The Company's 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. At year-end 1997 and 1996, the
    Company's cash equivalents also included investments in commercial paper
    and short-term certificates of deposits of the Company's foreign
    operations, which have an original maturity of three months or less. Cash
    equivalents are carried at cost, which approximates market value.

    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:

    Machinery, Equipment, and Leasehold Improvements
        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 using the straight-line method
    over the estimated useful lives of the property as follows: machinery and
    equipment, three to ten years and leasehold improvements, the lesser of
    the term of the lease or the life of the asset.

    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 $805,000 and $403,000 at January 3, 1998,
    and December 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 companies in
    assessing the recoverability of this asset. If impairment has occurred,
    any excess of carrying value over fair value is recorded as a loss.

    Foreign Currency
        All assets and liabilities of the Company's foreign subsidiaries are
    translated at year-end exchange rates, and revenues and expenses are
    translated at average exchange rates for the year in accordance with SFAS
    No. 52, "Foreign Currency Translation." Resulting translation adjustments
    are reflected as a separate component of shareholders' investment titled
    "Cumulative translation adjustment." Foreign currency transaction gains
    and losses are included in the accompanying statement of income and are
    not material for the three years presented.

    Fair Value of Financial Instruments
        The Company's financial instruments consist primarily of cash and
    cash equivalents, accounts receivable, promissory note to parent company,
    accounts payable, and due to parent company and affiliated companies.
    Their respective carrying amounts in the accompanying balance sheet
    approximate fair value due to their short-term nature, except for the
    promissory note to parent company. The carrying amount of the promissory
    note to parent company approximates fair value due to its variable
    interest rate.

    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.

    2.  Acquisitions

        On January 25, 1996, the Company acquired the assets of Moisture
    Systems Corporation and certain affiliated companies (collectively,
    Moisture Systems), and the stock of Rutter & Co. B.V. (Rutter) for a
    total purchase price of $21,668,000 in cash, which included the repayment
    of $700,000 of debt. Moisture Systems and Rutter design, manufacture, and
    sell instruments that use near-infrared spectroscopy to measure moisture

    2.  Acquisitions (continued)

    and other product constituents, including fats, proteins, oils,
    flavorings, solvents, adhesives, and coatings, in a variety of
    manufacturing processes. These systems are used in the food,
    pharmaceutical, chemical, pulp and paper, and other industries. To
    finance these acquisitions, the Company borrowed $21,200,000 from
    Thermedics pursuant to a promissory note due March 1998, bearing interest
    at the 90-day Commercial Paper Composite Rate plus 25 basis points, set
    at the beginning of each quarter. As of January 3, 1998, and December 28,
    1996, the interest rate on the promissory note was 5.76% and 5.77%,
    respectively. In December 1996, the Company acquired certain moisture
    measurement product lines for approximately $300,000 in cash. In
    addition, the Company has agreed to pay a licensing fee on sales of these
    products through December 2000.
        These acquisitions have been accounted for using the purchase method
    of accounting and their results of operations have been included in the
    accompanying financial statements from their respective dates of
    acquisition. The aggregate cost of Moisture Systems and Rutter exceeded
    the estimated fair value of the acquired net assets by $16,905,000, which
    is being amortized over 40 years. Allocation of the purchase price for
    these acquisitions was completed in 1997 and was based on estimates of
    the fair value of the net assets acquired.
        The following table presents selected financial information for the
    Company, Moisture Systems, and Rutter on a pro forma basis, assuming the
    companies had been combined since the beginning of 1995.

        The pro forma results are not necessarily indicative of future
    operations or the actual results that would have occurred had the
    acquisitions of Moisture Systems and Rutter been made at the beginning of
    1995.

    Stock-based Compensation Plans

    Stock Option Plan
    -----------------
        The Company has a stock-based compensation plan for its key
    employees, directors, and others, which permits 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. The option recipients and the terms of options
    granted under this plan are determined by the Board Committee. To date,
    only nonqualified stock options have been granted by the Board Committee
    under this plan. Options granted prior to the Company's initial public
    offering became exercisable in June 1997, but are subject to certain
                                       12PAGE

    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 generally ranges from seven to twelve years. Nonqualified stock
    options may be granted at any price determined by the Board Committee,
    although incentive stock options must be granted at not less than the
    fair market value of the Company's common stock on the date of grant. To
    date, all options have been granted at fair market value.

    3.  Employee Benefit Plans (continued)

    Employee Stock Purchase Program
    -------------------------------
        Substantially all of the Company's full-time U.S. employees are
    eligible to participate in an employee stock purchase program sponsored
    by Thermedics and Thermo Electron. Under this program, shares of
    Thermedics' and Thermo Electron's common stock may 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 Plans 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 25 in accounting for its stock-based compensation plans. Had
    compensation cost for awards in 1997 and 1996 under the Company's
    stock-based compensation plans been determined based on the fair value at
    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: 

    (In thousands except per share amounts)               1997        1996
    ----------------------------------------------------------------------
    Net income:
      As reported                                       $6,070      $  362
      Pro forma                                          5,485         102
    Basic and diluted earnings per share:
      As reported                                          .48         .04
      Pro forma                                            .43         .01

        Pro forma net income for 1995 was not materially different from
    historical net income in 1995. 
        Because the method prescribed by SFAS No. 123 has not been applied to
    options granted prior to January 1, 1995, the resulting pro forma
    compensation expense may not be representative of the amount to be
    expected in future years. Pro forma 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.

    3.  Employee Benefit Plans (continued)

        The weighted average fair value per share of options granted was
    $4.44, $3.76, and $4.15 in 1997, 1996, and 1995, respectively. The fair
    value of each option grant is estimated on the grant date using the
    Black-Scholes option-pricing model with the following weighted-average
    assumptions: 

                                                          1997       1996
    ---------------------------------------------------------------------
    Volatility                                             28%          -
    Risk-free interest rate                               6.1%       6.4%
    Expected life of options                         5.9 years  7.0 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. 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.

    401(k) Savings Plan
        Substantially all of the Company's full-time U.S. 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. For this plan, the Company contributed and
    charged to expense $302,000, $247,000, and $233,000 in 1997, 1996, and
    1995, respectively.

    Defined Benefit Pension Plan
        The Company's Rutter subsidiary, acquired in January 1996, has a
    defined benefit pension plan covering substantially all of its full-time
    employees. The Company's funding policy is to make contributions within a
    range required by applicable regulations in The Netherlands.
        Net periodic pension costs included the following components:

        Significant actuarial assumptions used to determine the net periodic
    pension cost were as follows: discount rate - 7.5%; rate of increase in
    salary levels up to age 45 - 4.5%; rate of increase in salary levels
    after age 45 - 2.5%; and expected long-term rate of return on assets -
    4.0%.

        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 $305,000 of such benefits that have been allocated to capital
    in excess of par value in 1997.
        The provision for income taxes in the accompanying statement of
    income differs from the provision calculated by applying the statutory
    federal income tax rate of 34% to income before provision for income
    taxes due to the following:

    $3,415,000 of undistributed earnings of foreign subsidiaries that could
    be subject to taxation if remitted to the U.S. because the Company
    currently plans to keep these amounts permanently reinvested overseas.

    5.  Commitments

        The Company leases portions of its office and operating facilities
    under various operating lease arrangements. The accompanying statement of
    income includes expenses from operating leases of $1,078,000, $1,335,000,
    and $542,000 in 1997, 1996, and 1995, respectively, net of third party
    sublease income of $181,000 in 1997. Total future minimum payments due
    under noncancelable operating leases at January 3, 1998, are $1,201,000
    in 1998; $1,039,000 in 1999; $878,000 in 2000; $779,000 in 2001; $797,000
    in 2002; and $2,918,000 in 2003 and thereafter. Total future minimum
    lease payments are $7,612,000 and have not been reduced by minimum
    sublease rental income of $1,160,000 due through 2002 under noncancelable
    operating subleases. See Note 6 for office and manufacturing space leased
    from a related party.

    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 paid Thermo Electron
    an annual fee equal to 1.0% of the Company's revenues in 1997 and 1996,
    and an amount equal to 1.20% of the Company's revenues in 1995. Beginning
    in fiscal 1998, the Company will pay an annual fee equal to 0.8% of the
    Company's revenues. The annual fee is reviewed and adjusted annually by
    mutual agreement of the parties. Management believes that the service fee

    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). In addition, the Company
    uses contract administration services of a majority-owned subsidiary of
    Thermo Electron and is charged based on actual usage. For these services,
    as well as the administrative services provided by Thermo Electron, the
    Company was charged $579,000, $438,000, and $335,000 in 1997, 1996, and
    1995, respectively. 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.

    Research and Development Agreement
        Pursuant to a subcontract entered into in October 1993, the Company
    performs research and development services for Thermo Coleman
    Corporation, which is the prime contractor under a contract with the U.S.
    Department of Energy. Thermo Coleman is a wholly owned subsidiary of
    Thermo Electron. Thermo Coleman paid the Company $533,000, $619,000, and
    $829,000 for services rendered in 1997, 1996, and 1995, respectively.

    Distribution Agreement
        Pursuant to an international distributorship agreement, the Company
    appointed Arabian Business Machines Co. (ABM) as its exclusive
    distributor of the Company's security instruments in certain Middle
    Eastern countries. ABM is a member of The Olayan Group. Ms. Hutham S.
    Olayan, a director of Thermo Electron, is the president and a director of
    Olayan America Corporation and Competrol Real Estate Limited, two other
    members of The Olayan Group, which are indirectly controlled by Suliman
    S. Olayan, Ms. Olayan's father. Revenues recorded under this agreement
    totaled $480,000, $652,000, and $3,000, in 1997, 1996, and 1995,
    respectively.

    Other Related-party Transactions
        The Company purchases and sells products in the ordinary course of
    business with other companies affiliated with Thermo Electron. Sales of
    products to such affiliated companies totaled $147,000, $114,000, and
    $122,000 in 1997, 1996, and 1995, respectively. Purchases of products
    from such affiliated companies totaled $237,000, $253,000, and $330,000
    in 1997, 1996, and 1995, respectively.

        Basic and diluted earnings per share were calculated as follows:

        The computation of diluted earnings per share for 1997 excludes the
    effect of assuming the exercise of certain outstanding stock options
    because the effect would be antidilutive. As of January 3, 1998, there
    were 342,240 of such options outstanding, with exercise prices ranging
    from $10.75 to $12.46 per share.

                    Report of Independent Public Accountants

    To the Shareholders and Board of Directors of Thermedics Detection Inc.:

        We have audited the accompanying consolidated balance sheet of
    Thermedics Detection Inc. (a Massachusetts corporation and 76%-owned
    subsidiary of Thermedics Inc.) and subsidiaries as of January 3, 1998,
    and December 28, 1996, and the related consolidated statements of income,
    cash flows, and shareholders' investment for each of the three years in
    the period ended January 3, 1998. 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 did not audit the financial statements of Rutter & Co.
    B.V. (a wholly owned subsidiary of Thermedics Detection Inc.), for the
    period from January 25, 1996 (the date of acquisition) through and as of
    December 28, 1996, and as of and for the year ended January 3, 1998,
    which statements reflect total assets and total revenues of 9% and 4% in
    1997, and 16% and 17% in 1996, respectively, of the consolidated totals.
    Those statements were audited by other auditors whose report has been
    furnished to us and our opinion, insofar as it relates to the amounts
    included for that entity, is based solely on the report of the other
    auditors.
        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 consolidated
    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 and the report of other auditors
    provide a reasonable basis for our opinion.
        In our opinion, based on our audits and the report of other auditors,
    the consolidated financial statements referred to above present fairly,
    in all material respects, the financial position of Thermedics Detection
    Inc. and subsidiaries as of January 3, 1998, and December 28, 1996, and
    the results of their operations and their cash flows for each of the
    three years in the period ended January 3, 1998, in conformity with
    generally accepted accounting principles.

                          Independent Auditor's Report

        We have audited the consolidated balance sheet of the Rutter & Co.
    B.V. segment of Thermedics Detection Inc. as of January 3, 1998, and
    December 28, 1996, and the related consolidated statements of income,
    stockholder's equity, and cash flows for the year ended January 3, 1998,
    and the period from January 25, 1996 (acquisition date) to December 28,
    1996 (all expressed in Netherlands Guilders) (not included herein). These
    financial statements are the responsibility of Thermedics Detection
    Inc.'s and Rutter & Co. B.V.'s management. Our responsibility is to
    express an opinion on these financial statements based on our audit.
        We conducted our audit in accordance with generally accepted auditing
    standards in the United States of America. Those standards require that
    we plan and perform the audit to obtain reasonable assurance about
    whether the financial statements are free of material misstatement. An
    audit includes examining, on a test basis, evidence supporting the
    amounts and disclosures in the financial statements. An audit also
    includes assessing the accounting principles used and significant
    estimates made by management, as well as evaluating the overall financial
    statement presentation. We believe that our audit provides a reasonable
    basis for our opinion.
        As discussed in the notes to the financial statements (not included
    herein), the consolidated balance sheet of the Rutter & Co. B.V. segment
    of Thermedics Detection Inc. includes the net assets acquired by
    Thermedics Detection Inc. in its purchase of Rutter & Co. B.V. on January
    25, 1996, after giving effect to the allocation of Thermedics Detection
    Inc.'s purchase price to the consolidated net assets of Rutter & Co.
    B.V., and to the changes in the consolidated net assets of Rutter & Co.
    B.V. subsequent to the acquisition; the related consolidated statements
    of income, stockholder's equity, and cash flows reflect the results of
    operations and cash flows of Rutter & Co. B.V. subsequent to such
    acquisition after giving effect to the allocation of Thermedics Detection
    Inc.'s purchase price to Rutter & Co. B.V.'s consolidated net assets.

                     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 develops, manufactures, and markets high-speed detection
    and measurement systems used in on-line industrial process and security
    applications, and laboratory analysis. The Company's industrial process
    systems use ultratrace chemical detectors, high-speed gas
    chromatography, X-ray imaging, near-infrared spectroscopy, and other
    technologies for quality assurance of in-process and finished products,
    primarily in the food, beverage, pharmaceutical, forest products,
    chemical, and other consumer products industries. The Company's security
    instruments use simultaneous trace particle- and vapor-detection
    techniques based on its proprietary chemiluminesence and high-speed gas
    chromatography technologies. Customers use the Company's security
    instruments to detect plastic and other explosives at airports and border
    crossings, for other high-security screening applications, and for
    forensics and search applications.
        Historically, the Company's principal product lines were process
    detection systems, including Alexus(R) systems used to assure the quality
    of refillable plastic containers, and EGIS(R) explosives detectors. The
    Company expanded its product lines to include moisture analysis equipment
    through its acquisitions of Moisture Systems Corporation and Rutter & Co.
    B.V. in January 1996, and also introduced its InScan(TM) high-speed X-ray
    imaging systems (InScan systems) and Flash-GC(TM) gas chromatography
    systems (Flash-GC systems) in 1996. The Company has also recently
    introduced Rampart(TM), the latest portable trace-detection system that
    incorporates the advanced Flash-GC technology in tandem with a highly
    sensitive chemiluminesence detector. The Company also performs contract
    research and development services for government and industry customers
    and earns service revenues through long-term contracts.
        A substantial portion of the Company's sales are derived from sales
    of products outside the United States, through export sales, and sales by
    the Company's foreign subsidiaries. Although the Company seeks to charge
    its customers in the same currency as its operating costs, the Company's
    financial performance and competitive position can be affected by
    currency exchange-rate fluctuations.

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

    Results of Operations

    1997 Compared With 1996
        Revenues increased 17% to $51.3 million in 1997 from $43.8 million in
    1996. Product revenues increased 21% to $37.8 million in 1997 from $31.3
    million in 1996, while service revenues increased 9% to $13.6 million in
    1997 from $12.5 million in 1996. Revenues from the Company's process
    detection instruments and related services increased to $22.4 million in
    1997 from $16.0 million in 1996, primarily due to Alexus revenues of $6.6
    million from the fulfillment of a mandated product-line upgrade from The
    Coca-Cola Company to its existing installed base and, to a lesser extent,
    increased shipments of the Company's InScan systems, which were
    introduced in 1996. The mandated product-line upgrade was completed in
    1997. These increases were offset in part by a decrease in demand from
    The Coca-Cola Company for new installations in 1997. As a result of this
    decrease in demand and the completion of the product-line upgrade, the
    Company anticipates that sales of Alexus systems will slow in 1998, which
    is the primary reason for a $5.0 million decrease in the Company's
    backlog in 1997. Revenues from the Company's EGIS security systems and
    related services increased to $10.3 million in 1997 from $7.1 million in
    1996, primarily due to $3.2 million of shipments under the Company's
    contract with the Federal Aviation Administration (FAA). Revenues from
    the Company's Moisture Systems and Rutter subsidiaries, acquired in
    January 1996, decreased to $15.4 million in 1997 from $18.0 million in
    1996, primarily due to a slowdown in product demand in Europe in 1997,
    offset in part by the inclusion of revenues for the full year of 1997.
        The gross profit margin increased to 52% in 1997 from 49% in 1996.
    The gross profit margin on product revenues increased to 54% in 1997 from
    50% in 1996, primarily due to a change in product mix to higher-margin
    revenues from The Coca-Cola Company's mandated product-line upgrade, as
    well as higher-margin revenues at Moisture Systems and Rutter. To a
    lesser extent, the increase also resulted from the inclusion of an $0.8
    million charge in 1996 as a result of obsolescence created by planned
    product changes. The gross profit margin on service revenues increased to
    46% in 1997 from 44% in 1996, primarily due to increased field service
    efficiencies and, to a lesser extent, the change in sales mix to
    higher-margin service revenues at Moisture Systems and Rutter.
        Selling, general, and administrative expenses as a percentage of
    revenues decreased to 25% in 1997 from 34% in 1996. The decline was
    primarily due to nonrecurring costs in 1996 related to a reduction in
    personnel and a reduction in leased space in response to a lower sales
    volume of process detection instruments and, to a lesser extent, an
    increase in revenues in 1997. This decrease was offset in part by
    increased selling expenses as the Company developed a sales force for its
    InScan and Flash-GC systems.
        Research and development expenses increased to $5.1 million in 1997
    from $4.7 million in 1996, primarily due to costs related to the
    improvement and expansion of Moisture System's moisture analysis
    equipment product line.

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

    1997 Compared With 1996 (continued)
        Interest income increased to $2.1 million in 1997 from $0.2 million
    in 1996, primarily due to interest income earned on the invested proceeds
    from the Company's March 1997 initial public offering (Note 7).
        Interest expense, related party, of $1.2 million and $1.1 million in
    1997 and 1996, respectively, reflects the issuance of a $21.2 million
    promissory note to Thermedics in connection with the January 1996
    acquisitions of Moisture Systems and Rutter (Note 2).
        The effective tax rate was 39% in 1997 and 1996. The effective tax
    rates in both periods exceeded the statutory federal income tax rate
    primarily due to the impact of state income taxes.
        The Company is currently assessing the potential impact of the year
    2000 on the processing of date-sensitive information by the Company's
    computerized information systems and on products sold as well as products
    purchased by the Company. The Company believes that its internal
    information systems and current products are either year 2000 compliant
    or will be so prior to the year 2000 without incurring material costs.
    There can be no assurance, however, that the Company will not experience
    unexpected costs and delays in achieving year 2000 compliance for its
    internal information systems and current products, which could result in
    a material adverse effect on the Company's future results of operations.
        The Company is presently assessing the effect that the year 2000
    problem may have on its previously sold products. The Company is also
    assessing whether its key suppliers are adequately addressing this issue
    and the effect this might have on the Company. The Company has not
    completed its analysis and is unable to conclude at this time that the
    year 2000 problem as it relates to its previously sold products and
    products purchased from key suppliers is not reasonably likely to have a
    material adverse effect on the Company's future results of operations.

    1996 Compared With 1995
        Revenues increased 57% to $43.8 million in 1996 from $28.0 million in
    1995. Product revenues increased 69% to $31.3 million in 1996 from $18.5
    million in 1995, while service revenues increased 32% to $12.5 million in
    1996 from $9.5 million in 1995. Revenues increased in 1996 due to the
    inclusion of $18.0 million in revenues from Moisture Systems and Rutter,
    which were acquired in January 1996. Revenues from the Company's process
    detection instruments and related services decreased to $16.0 million in
    1996 from $18.5 million in 1995, primarily due to a decrease in demand
    from the Coca-Cola Company, which have substantially completed their
    initial deployment of Alexus systems. Revenues from the Company's
    security systems and related services increased to $7.1 million in 1996
    from $4.6 million in 1995, primarily due to the sale of eight EGIS units
    to the U.S. government to provide counterterrorism support in Israel.
    Revenues from research and development contracts decreased by $2.2
    million to $1.8 million in 1996 due to the completion of a commercial
    contract with the Miller Brewing Company for the InScan system and, to a
    lesser extent, the completion of various phases of government contracts,
    which have since been renewed.
        The gross profit margin increased to 49% in 1996 from 45% in 1995.
    The gross profit margin on product revenues increased to 50% in 1996 from

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

    1996 Compared With 1995 (continued)
    46% in 1995, primarily due to higher-margin revenues from Moisture
    Systems and Rutter, offset in part by an inventory write-down of $0.8
    million in 1996 due to obsolescence created by planned product changes.
    The gross profit margin on service revenues remained unchanged at 44% in
    1996 and 1995.
        Selling, general, and administrative expenses as a percentage of
    revenues increased to 34% in 1996 from 27% in 1995, primarily due to
    higher expenses as a percentage of revenues at Moisture Systems and
    Rutter and, to a lesser extent, $0.4 million of costs incurred in 1996
    related to reductions in personnel and a reduction in leased space in
    response to the lower sales volume of process detection instruments.
        Research and development expenses increased to $4.7 million in 1996
    from $2.7 million in 1995, primarily due to research and development
    relating to the Company's Flash-GC and InScan systems. In addition, the
    Company recorded a nonrecurring charge of $0.2 million in 1996 for the
    write-off of certain research and development equipment no longer of use.
        Interest expense, related party, of $1.1 million in 1996 reflects the
    issuance of a $21.2 million promissory note to Thermedics in connection
    with the January 1996 acquisitions of Moisture Systems and Rutter.
        The effective tax rates were 39% and 38% in 1996 and 1995,
    respectively. The effective tax rates in both periods exceeded the
    statutory federal income tax rate primarily due to the impact of state
    income taxes. 

    Liquidity and Capital Resources

        Consolidated working capital was $37.2 million at January 3, 1998,
    compared with $23.4 million at December 28, 1996. Included in working
    capital are cash and cash equivalents of $44.7 million at January 3,
    1998, compared with $13.5 million at December 28, 1996.
        During 1997, $3.9 million of cash was provided by operating
    activities. During this period, cash of $2.2 million and $2.0 million was
    used to fund increases in accounts receivable and inventories,
    respectively, primarily relating to an order received from the FAA, which
    provides for extended payment terms and resulted in inventory purchases.
    This use of cash was offset in part by $1.7 million of cash provided by
    an increase in other current liabilities, including $0.9 million of
    accrued income taxes.
        During 1997, the Company's investing activities included the
    expenditure of $0.8 million for purchases of machinery, equipment, and
    leasehold improvements. During 1998, the Company expects to make capital
    expenditures of approximately $0.8 million.
        The Company's financing activities provided $28.0 million of cash in
    1997. In March 1997, the Company sold 2,671,292 shares of its common
    stock in an initial public offering for net proceeds of $28.1 million. In
    the first quarter of 1998, the Company expects to repay its $21.2 million
    promissory note to Thermedics (Note 2).
        Although the Company expects to have positive cash flow from its
    existing operations, the Company anticipates it will require significant
    amounts of cash for the possible acquisition of complementary businesses

    and technologies. While the Company currently has no agreement to make an
    acquisition, it expects that it would finance any acquisition through a
    combination of internal funds, additional debt or equity financing,
    and/or short-term borrowings from Thermedics or Thermo Electron, although
    it has no agreement with these companies to ensure that funds will be
    available on acceptable terms or at all. The Company believes that its
    existing resources are sufficient to meet the capital requirements of its
    existing businesses 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 1998 and beyond to differ
    materially from those expressed in any forward-looking statements made
    by, or on behalf of, the Company.

        Uncertainty of Market Acceptance of New Products. Certain of the
    Company's products represent alternatives to traditional detection and
    analytical methods. As a result, such products may be slow to achieve, or
    may not achieve, market acceptance, as customers may seek further
    validation of the efficiency and efficacy of the Company's technology,
    particularly where the purchase of the product requires a significant
    capital commitment. The Company believes that, to a significant extent,
    its growth prospects depend on its ability to gain acceptance of the
    efficiency and efficacy of the Company's innovative technologies by a
    broader group of customers. The Company is currently devoting significant
    resources toward the enhancement of its existing products and the
    development of new products and technologies, including its derivative
    products of the Company's Flash-GC high-speed gas chromatography system;
    a more portable EGIS; and Rampart, a lower-cost EGIS unit for use in
    airport screening of carry-on baggage. There can be no assurance that the
    Company will be successful in obtaining such broad acceptance or that, if
    obtained, such acceptance will be sustained. The failure of the Company
    to obtain and sustain such broad acceptance could have a material adverse
    effect on the Company's business, financial condition and results of
    operations. 
        Ongoing Product Development Efforts Required by Rapid Technological
    Change. The markets for the Company's products are characterized by
    changing technology, evolving industry standards and new product
    introductions. The Company's future success will depend in part upon its
    ability to enhance its existing products and to develop and introduce new
    products and technologies to meet changing customer requirements. There
    can be no assurance that the Company will successfully complete the
    enhancement and development of these products in a timely fashion or that
    the Company's current or future products will satisfy the needs of its
    markets.

        Dependence of Security Instruments Market on Government Regulation
    and Airline Industry. The Company's sales of its explosives-detection
    systems for use in airports has been and will continue to be dependent on
    governmental initiatives to require, or support, the screening of checked
    luggage, carry-on items and personnel with advanced explosives-detection
    equipment. Substantially all of such systems have been installed at
    airports in countries other than the United States, in which the
    applicable government or regulatory authority overseeing the operations
    of the airport has mandated such screening. Such mandates are influenced
    by many factors outside of the control of the Company, including
    political and budgetary concerns of governments, airlines, and airports.

                           Forward-looking Statements

    Of the more than 600 commercial airports worldwide, more than 400 are
    located in the United States. Accordingly, the Company believes that the
    size of the market for explosives-detection equipment is, and will
    increasingly be, significantly influenced by United States government
    regulation. In the United States, the Aviation Security Act of 1990
    directed the Federal Aviation Administration (FAA) to develop a standard
    for explosives-detection systems and required airports in the United
    States to deploy systems meeting this standard in 1993. To date, no
    system has demonstrated that it meets all FAA standards under realistic
    airport operating conditions. As a result, the FAA has not mandated the
    installation of automated explosives-detection systems, and only a
    limited number of these systems have been deployed in the United States.
    The FAA first certified a computed X-ray tomography system for checked
    luggage in December 1994. The Company's systems are trace detectors for
    which no FAA certification process for checked baggage, carry-on, or
    personal screening exists to date. Currently, the Company is seeking FAA
    approval for the Company's EGIS and Ramport systems for use by airlines
    in screening carry-on electronic items and luggage searches, however,
    there can be no assurance that such FAA approvals will be obtained. Each
    airline must seek this approval for each application. Although the FAA
    has provided significant funding to the Company in connection with the
    development of its explosives-detection technology, there can be no
    assurance that any of the Company's systems will ever meet this or any
    other United States certification standard. Any product utilizing a
    technology ultimately recommended or required by the FAA will have a
    significant competitive advantage in the market for explosives-detection
    devices. Unless the FAA takes action with respect to a particular
    explosives-detection product or technology, airlines will not be required
    to purchase or upgrade their security systems, including upgrading
    existing metal-detection equipment. Earnings of U.S. air carriers tends
    to fluctuate significantly from time to time. Any depression in the
    financial condition of such carriers would likely result in lower capital
    spending for discretionary items. Moreover, there can be no assurance
    that additional countries will mandate the implementation of effective
    explosives screening for airline baggage, carry-on items or personal, or
    that, if mandated, the Company's systems will meet the certification or
    other requirements of the applicable government authority. Even if the
    Company's systems were to meet the applicable requirements, there can be
    no assurance that the Company would be able to market its systems
    effectively.
        In October 1996, the United States enacted legislation which includes
    a $144.2 million allocation to purchase explosives-detection systems and
    other advanced security equipment, including trace detection equipment
    such as the systems manufactured by the Company, for carry-on and checked
    baggage screening. The FAA has made purchases of, or placed orders for
    the purchase of, security equipment under this legislation, including an
    order to purchase $5.8 million of the Company's EGIS systems. There can
    be no assurance, however, that this legislation will not be modified to
    reduce the funding for advanced explosives equipment, that the necessary
    appropriations will be made to fund further purchases of advanced
    explosives-detection equipment contemplated by the legislation, that
    trace-detection equipment such as the systems manufactured by the Company

                           Forward-looking Statements

    will be mandated, or that, even if further appropriations are made and
    such equipment is mandated, any of the Company's explosives-detection
    systems will be purchased for installation at any airports in the United
    States. Further, there can be no assurance that the U.S. will mandate the
    widespread use of these systems after completion of the initial
    purchases.

        Significance of Certain Customers. Sales of process detection
    instruments and services to bottlers licensed by The Coca-Cola Company
    (Coca-Cola Bottlers) were $13,939,000, $10,641,000, and $9,974,000, in
    1997, 1996, and 1995, respectively, or 27%, 24%, and 36% of the Company's
    revenues, respectively, during such periods. In 1997, the Company
    completed the fulfillment of a mandated product-line upgrade for The
    Coca-Cola Bottlers. Although the Company anticipates that it will
    continue to derive revenues from the sale of upgrades and new systems to
    new plants, as well as services to the Coca-Cola Bottlers, the Company
    does not expect that revenues derived from these customers will continue
    at a rate comparable to prior years. Further, the Company intends to
    continue to develop and introduce new process detection products for the
    food, beverage and other markets, however, there can be no assurance that
    the Company will be successful in the introduction of new process
    detection products or that any sales of these products will be sufficient
    to maintain a rate of growth equivalent to prior years. 

        Competition; Technological Change. The Company encounters, and
    expects to continue to encounter, competition in the sale of its current
    and future products. Many of the Company's competitors and potential
    competitors have substantially greater resources, manufacturing and
    marketing capabilities, research and development staff and production
    facilities than those of the Company. Some of these competitors have
    large existing installed bases of products with substantial numbers of
    customers. In addition, other major corporations have recently announced
    their intention to enter certain of the Company's markets, including the
    security screening market. The Company believes that many of its products
    are successful because they are technologically superior to alternative
    products offered by some of the Company's competitors. In order to
    continue to be successful, the Company believes that it will be important
    to maintain this technological advantage. No assurance can be given that
    the Company will be able to maintain such an advantage or that
    competitors of the Company will not develop technological innovations
    that will render products of the Company obsolete. For example, the
    Company's EGIS system competes against other trace explosives detection
    systems as well as systems utilizing dual energy X-ray or computed X-ray
    tomography imaging technologies. There can be no assurance that such
    technologies will not be enhanced to a degree that would impair the
    Company's ability to market its explosives detection systems. 

        Potential for Product Liability Claims. The Company's business
    involves the risk of product liability claims inherent to the explosives
    detection business, as well as the food, beverage and other industries.
    There are many factors beyond the control of the Company that could

    result in the failure of the Company's products to detect explosives or
    contaminants in food or beverage containers, such as the reliability of a
    customer's operators, the ongoing training of such operators and the
    maintenance of the Company's products by its customers. For these and
    other reasons, there can be no assurance that the Company's products will
    detect all explosives or contaminants. The failure to detect explosives
    or contaminants could give rise to product liability claims and result in
    negative publicity that could have a material adverse effect on the
    Company's business, financial condition and results of operations. The
    Company currently maintains both aviation and general product liability
    insurance in amounts the Company believes to be commercially reasonable.
    There can be no assurance that this insurance will be sufficient to
    protect the Company from product liability claims, or that product
    liability insurance will continue to be available to the Company at a
    reasonable cost, if at all. 

        Uncertainties Associated With International Operations. In 1997,
    1996, and 1995, international sales accounted for 71%, 67%, and 73%,
    respectively, of the Company's revenues, and the Company anticipates that
    international sales will continue to account for a significant percentage
    of the Company's revenues. Sales to customers in The Netherlands
    accounted for approximately 17% and 11% of the Company's revenues in 1997
    and 1996, respectively. See Note 8 of Notes to the Company's Consolidated
    Financial Statements. International revenues are subject to a number of
    uncertainties, 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; fluctuations in exchange rates may affect product demand
    and adversely affect the profitability in U.S. dollars of products and
    services provided by the Company in foreign markets where payment for the
    Company's products and services is made in the local currency; U.S.
    export licenses may be difficult to obtain; and the protection of
    intellectual property in foreign countries may be more difficult to
    enforce. Moreover, many foreign countries have their own regulatory
    approval requirements for sales of the Company's products. As a result,
    the Company's introduction of new products into international markets can
    be costly and time-consuming, and there can be no assurance that the
    Company will be able to obtain the required regulatory approvals on a
    timely basis, if at all. There can be no assurance that any of these
    factors will not have a material adverse effect on the Company's
    business, financial condition and results of operations. The Company does
    not attempt to minimize currency and exchange rate risks through material
    hedging activities. 

        Limited Protection of Proprietary Technology and Risks of Third-Party
    Claims. Proprietary rights relating to the Company's products will be
    protected from unauthorized use by third parties only to the extent that
    they are covered by valid and enforceable patents or are maintained in
    confidence as trade secrets. There can be no assurance, however, that any
    patents now or hereafter owned by the Company will afford protection

    against competitors, or as to the likelihood that patents will issue from
    pending patent applications. Proceedings initiated by the Company to
    protect its proprietary rights could result in substantial costs to the
    Company. Although the Company believes that its products and technology
    do not infringe any existing proprietary rights of others, there can be
    no assurance that third parties will not assert such claims against the
    Company in the future or that such future claims will not be successful.
    The Company could incur substantial costs and diversion of management
    resources in connection with the defense of any claims relating to
    proprietary rights, which could have a material adverse effect on the
    Company's business, financial condition, and results of operations.
    Furthermore, parties making such claims could secure a judgment awarding
    substantial damages, as well as injunctive or other equitable relief,
    which could effectively block the Company's ability to make, use, sell,
    distribute or market its products and services in the U.S. or abroad.
    Such a judgment could have a material adverse effect on the Company's
    business, financial condition and results of operations. In the event
    that a claim relating to proprietary technology or information is
    asserted against the Company, the Company may seek licenses to such
    intellectual property. There can be no assurance, however, that such a
    license could be obtained on commercially reasonable terms, if at all, or
    that the terms of any offered licenses will be acceptable to the Company.
    The failure to obtain the necessary licenses or other rights could
    preclude the sale, manufacture or distribution of the Company's products
    and, therefore, could have a material adverse effect on the Company's
    business, financial condition and results of operations. The cost of
    responding to any such claim may be material, whether or not the
    assertion of such claim is valid. There can be no assurance that the
    steps taken by the Company to protect its proprietary rights will be
    adequate to prevent misappropriation of its technology or independent
    development by others of similar technology. In addition, the laws of
    some jurisdictions do not protect the Company's proprietary rights to the
    same extent as the laws of the U.S. There can be no assurance that these
    protections will be adequate.

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

        Difficulties in Managing Rapid Growth. Due to the level of technical
    and marketing expertise necessary to support its existing and new
    customers, the Company must attract and retain highly qualified and
    well-trained personnel. There are a limited number of persons with the
    requisite skills to serve in these positions, and it may become
    increasingly difficult for the Company to hire such personnel. Further
    rapid expansion may also significantly strain the Company's
    administrative, operational and financial personnel, management
    information systems, manufacturing operations, and other resources. There
    can be no assurance that the Company's systems, procedures, and controls
    will be adequate to support the Company's operations. Failure to manage
    growth properly could have a material adverse effect on the Company's
    business, financial condition, and results of operations. 

        Potential Fluctuations in Quarterly Performance. Significant annual
    and quarterly fluctuations in the Company's results of operations may be
    caused by, among other factors, the overall demand for, and market
    acceptance of, the Company's products; the timing of regulatory approvals
    for certain of the Company's products; government initiatives to promote
    the use of explosives detection systems such as those manufactured and
    sold by the Company; the timing of the announcement, introduction and
    delivery of new products and product enhancements by the Company and its
    competitors; variations in the Company's product mix and component costs;
    timing of customer orders; adjustments of delivery schedules to
    accommodate customer's programs; the availability of components from
    suppliers; the timing and level of expenditures in anticipation of future
    sales; the mix of products sold by the Company; and pricing and other
    competitive conditions. Because certain of the Company's products require
    significant capital expenditures and other commitments by its customers,
    the Company has experienced extended sales cycles. Delays in anticipated
    purchase orders could have a material adverse effect on the Company's
    business, financial condition and results of operations. Customers may
    also cancel or reschedule shipments, and product difficulties could delay
    shipments. Because the Company's operating expenses are based on
    anticipated revenue levels and a high percentage of the Company's
    expenses are fixed for the short term, a small variation in the timing of
    recognition of revenue can cause significant variations in operating
    results from quarter to quarter. There can be no assurance that any of
    these factors will not have a material adverse impact on the Company's
    business and results of operations. 

        Potential Impact of Year 2000 on Processing of Date-sensitive
    Information. The Company is currently assessing the potential impact of
    the year 2000 on the processing of date-sensitive information by the
    Company's computerized information systems and on products sold as well
    as products purchased by the Company. The Company believes that its
    internal information systems and current products are either year 2000
    compliant or will be so prior to the year 2000 without incurring material
    costs. There can be no assurance, however, that the Company will not
    experience unexpected costs and delays in achieving year 2000 compliance
    for its internal information systems and current products, which could

    result in a material adverse effect on the Company's future results of
    operations.
      The Company is presently assessing the effect that the year 2000
    problem may have on its previously sold products. The Company is also
    assessing whether its key suppliers are adequately addressing this issue
    and the effect this might have on the Company. The Company has not
    completed its analysis and is unable to conclude at this time that the
    year 2000 problem as it relates to its previously sold products and
    products purchased from key suppliers is not reasonably likely to have a
    material adverse effect on the Company's future results of operations.
