    Item 1. Business

    (a) General Development of Business

        Thermo Vision Corporation (the Company or the Registrant) designs,
    manufactures, and markets a diverse array of photonics products --
    light-based technologies for scientific and industrial applications --
    including optical components, imaging sensors and systems, lasers,
    optically based instruments, optoelectronics, and fiber optics. The
    Company sells photonics products in multiple markets across a number of
    industries for research, testing, detecting, and manufacturing
    applications. The Company's products range from optical filters used in
    blood glucose monitoring, to charge-injection devices (CIDs) used in
    optical spectroscopy, to specialty light sources used for quality
    assurance in semiconductor photolithography. Many of the Company's
    customers are manufacturers that incorporate the Company's products into
    medical and dental diagnostic instruments, analytical instruments,
    equipment for semiconductor manufacturing, and X-ray screening devices.

        The Company was incorporated in November 1995 as a wholly owned
    subsidiary of Thermo Optek Corporation, a publicly traded, majority-owned
    subsidiary Thermo Instrument Systems Inc. The Company initially comprised
    two businesses: Scientific Measurement Systems Inc. (now called Thermo
    Vision Colorado), a manufacturer of optically based instruments, and CID
    Technologies Inc. (CIDTEC), a manufacturer of sensors and cameras based
    on proprietary charge-injection device (CID) technology. Since February
    1996, the Company has acquired four businesses from unrelated third
    parties that currently constitute the bulk of its operations. In February
    1996, the Company acquired Oriel Corporation, a manufacturer and
    distributor of photonics components and instruments, for $11.8 million in
    cash and the assumption of $0.7 million in debt, and the assets of Corion
    Corporation, a manufacturer of commercial optical filters, for
    $5.1 million in cash. In February 1997, the Company acquired Laser
    Science, Inc. (LSI), a manufacturer of nitrogen, tunable dye, and pulsed
    CO(2) lasers, for $3.6 million in cash. In July 1997, the Company
    acquired the assets of Centronic, Inc. (now called Centro Vision, Inc.),
    a manufacturer of silicon photodiodes, for $3.8 million in cash. In
    August 1997, the Company acquired the crystal-materials business (Hilger
    Crystals Limited) of Hilger Analytical Limited, a wholly owned subsidiary
    of Thermo Optek, for the assumption of $908,000 of Thermo Optek's
    existing obligation under a line of credit. Hilger Crystals Limited
    (Hilger) manufactures crystals used for X-ray scintillation and infrared
    spectroscopy. Because the Company and Hilger were deemed for accounting
    purposes to be under control of their common owner, Thermo Optek, the
    transaction has been accounted for at historical cost in a manner similar
    to a pooling of interests. Accordingly, all historical information
    presented includes the results of operations of Hilger since 1993, the
    year in which it was acquired by Thermo Optek.

        In December 1997, the Company was "spun out" through a distribution
    of all of its outstanding capital stock as a dividend to Thermo Optek
    shareholders. Thermo Optek received a favorable private letter ruling
    from the Internal Revenue Service stating that the distribution qualifies
    as tax free. Thermo Vision is now a majority-owned public subsidiary of 

                                        2PAGE
<PAGE>
    Thermo Instrument. Also in December 1997, the Company sold 1,139,491
    shares of its common stock in an initial public offering, at $7.50 per
    share for net proceeds of $7,033,000.

        As of January 3, 1998, Thermo Instrument owned 6,299,552 shares of
    the common stock of the Company, representing 78% of such stock
    outstanding. Thermo Instrument develops, manufactures, markets, and
    services instruments and software used for the identification and
    quantification of complex molecular compounds and elements in gases,
    liquids, and solids. Uses include pharmaceutical drug research and
    clinical diagnostics, monitoring and measuring environmental pollutants,
    industrial inspection, and test and control for quality assurance and
    productivity improvement. In addition, Thermo Instrument develops,
    manufactures, markets, and services equipment for the measurement,
    preparation, storage, and automation of sample materials, and photonics
    and vacuum components for original equipment manufacturers. As of January
    3, 1998, Thermo Electron Corporation owned 102,349 shares of the common
    stock of the Company, representing 1% of such stock outstanding. 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; and other specialized products. Thermo
    Electron also provides industrial outsourcing, particularly in
    environmental-liability management, laboratory analysis, and
    metallurgical services, and conducts advanced-technology research and
    development.

    (c) Description of Business

        (i) Principal Products and Services

        Photonics is the practical use of light. In many ways, photonics is
    analogous to electronics. Photonic technologies use light to detect,
    transmit, store, and process information, and to generate energy, as well
    as to capture and display images. The basic unit of light is the photon,
    while in electronics it is the electron. Because photons are massless and
    travel faster than electrons, photonic devices can be made smaller and
    significantly faster than electronic devices. For example, replacing
    electronics (copper wire) with photonics (fiber-optic cable) boosts the
    capacity of telecommunication transmission lines by a factor of 10,000.

        Photonic components are the "enabling technology" in many familiar
    consumer products, including CD-ROM players, digital cameras, displays on
    laptop computers and calculators, and fiber optic cable for telephones,
    cable television, and networked computer systems. In industry, photonics
    "eyes" enable robots to "see." Photonics is also found in semiconductor
    manufacturing as well as analytical and process-monitoring applications.
    In medicine, photonics is at the core of diagnostic instrumentation,
    laser microsurgery, and filmless real-time dental X-ray images.

        The Company estimates that the growing worldwide photonics industry
    currently totals approximately $15.5 billion. The industry is typically
    classified in terms of technologies rather than end-user applications,
    using the following six market segments. The Company offers products in
    each of these categories:

        Optical Components. Light sources, filters, crystals, prisms, lenses,
    and precision mechanical-positioning devices are all optical components.
    Primary applications for optical components include semiconductor
    production, medical and analytical instruments, and telecommunications.
    The Company offers a broad line of optical components designed for
    specific applications and for use in modular systems.

        Imaging Sensors and Systems. Imaging sensors detect photons and
    produce a resultant electrical signal. An imaging system consists of a
    sensor or an array of sensors connected to a recording and/or display
    device. Applications of imaging sensors and systems include cameras for
    filmless dental X-ray imaging and detectors for optical spectrometers
    used in chemical analysis. The Company's sensors are designed to have
    very high dynamic range at low light levels, which makes them attractive
    in demanding spectroscopy and astronomy applications. The Company offers
    a number of proprietary CID sensors based on its own designs and
    customizes sensors to particular customer specifications. The Company
    also designs and markets CID camera systems.

        Lasers. A laser is a specialized light source that produces an
    intense beam of highly monochromatic, coherent radiation, or light. The
    Company designs, manufactures, and markets pulsed nitrogen lasers,
    nitrogen laser accessories, and pulsed CO(2) lasers. Pulsed lasers are
    preferable to continuous lasers in measurement applications because the
    break in the laser beam provides discrete time segments in which to

                                        4PAGE
<PAGE>
    perform measurements. The Company's lasers are often used as the
    ionization sources for matrix assisted laser desorption ionization-time
    of flight (MALDI-TOF) mass spectrometers used to study proteins,
    peptides, and other large biomolecules, as well as for the cutting of
    samples mounted in a microscope.

        Optically Based Instruments. Optically based instruments combine
    optical components and signal processors and are used primarily in
    analytical and process applications, such as the determination of correct
    exposure time for photoresist development in photolithography,
    identification of materials by their fluorescence lifetime, and the
    quality testing of optical components. The Company focuses on the
    development of low-cost analyzers that use standard photonics components
    as building blocks designed to work together in multiple configurations
    and to be easily modified to accommodate changing end-user requirements.

        Optoelectronics. These devices convert light to electricity or
    electricity to light. A familiar example is the silicon photodiode
    detector, with uses ranging from orienting satellites toward the sun to
    color recognition for paint matching. The Company customizes its
    photodiodes for specific applications. The primary customers for the
    Company's optoelectronic products are manufacturers of medical diagnostic
    and analytical instruments.

        Fiber Optics. Fiber optics are single or bundled fibers that transmit
    light down their length. Fiber optics are used to economically move light
    in optically based instruments and for remote sensing applications for
    chemical testing in hostile environments. Most of the specialty fiber-
    optic cable that the Company sells is used for remote sensing.

    Sales and Marketing

        The Company markets its products both in the U.S. and internationally
    by means of technical catalogs, available in printed format and, in the
    future, on CD-ROMs, as well as through Web sites and the dealer and
    distributor networks of its subsidiaries and divisions. The Company sells
    directly to larger OEM buyers through the direct sales forces of its
    subsidiaries and divisions. The Company trains the members of its sales
    forces on the technical aspects of its products so they are able to
    respond to questions and otherwise support customers, dealers, and
    distributors. The Company holds a minority equity interest in LOT-Oriel
    Holding GmbH (LOT-Oriel), a large European distributor of photonics
    products. A representative of the Company serves as a member of
    LOT-Oriel's board of directors. The Company believes that its
    relationship with LOT-Oriel enhances the Company's visibility in and
    access to the European photonics market.

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

        The Company maintains active programs for the development of new
    technologies and the enhancement of its existing products. In addition,
    the Company seeks to develop new applications for its products and
    technologies. The Company incurred research and development expenses of
    $4,143,000, $3,499,000, and $743,000 in 1997, 1996, and 1995,

                                        5PAGE
<PAGE>
    respectively. In addition, the Company received $744,000, $532,000, and
    $490,000 for customer-sponsored contract research and development
    expenses in 1997, 1996, and 1995, respectively.

        (iii) Raw Materials

        The Company purchases the silicon wafers used in its CID sensors and
    silicon photodiodes from third-party manufacturers that process the
    wafers in accordance with the Company's designs and specifications. The
    Company currently purchases CID wafers from a single supplier, although
    it is exploring alternative sources of supply and believes that a number
    of other qualified wafer fabricators are available. The Company purchases
    CID wafers from its existing supplier on a purchase-order basis and does
    not have a formal supply arrangement with this company. The Company
    believes that outsourcing the processing of these wafers enables it to
    avoid the technological risks and significant capital costs associated
    with maintaining its own wafer fabrication lines.

        (iv) Patents, Licenses, and Trademarks

        The Company's success depends in part on the strength and protection
    of its proprietary methodologies and designs and other proprietary
    intellectual rights. The Company's policy is to protect its intellectual
    property rights and to apply for patent protection when appropriate. The
    Company believes that its manufacturing know-how, particularly with
    respect to its optical filters and crystals, provides it with a
    competitive advantage.

        The Company currently holds numerous issued U.S. patents expiring at
    various dates ranging from 1999 to 2016. The Company also has a number of
    applications pending for additional U.S. patents and a number of foreign
    counterparts for its patents in various foreign countries. The Company
    also has certain registered and other trademarks. In addition, the
    Company has entered into license agreements with other companies pursuant
    to which it grants or receives the rights to certain technology,
    know-how, trademarks, or patents. Several of the Company's issued U.S.
    patents pertain to its CID technology. In addition, the Company holds a
    nonexclusive license to certain additional patents relating to CID
    technology.

        (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.

                                        6PAGE
<PAGE>
        (vii) Dependency on a Single Customer

        No single customer accounted for more than 10% of the Company's total
    revenues in any of the past three years.

        (viii) Backlog

        The Company's backlog of firm orders was $12.3 million and $9.2
    million 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 1998.

        (ix) Government Contracts

        Not applicable.

        (x) Competition

        The photonics industry is highly competitive. The Company competes
    with a number of companies, many of which have substantially greater
    financial, marketing, and other resources than the Company. The Company's
    principal competitors include Coherent, Inc.; Corning OCA Corporation;
    the Bicron Business Unit of Saint-Gobain Industrial Ceramics, Inc.;
    Melles-Griot, Inc.; Newport Corporation; Optical Coating Laboratory,
    Inc.; Hamamatsu Corporation, a unit of Hamamatsu Photonic KK; and UDT
    Sensors, Inc., an Opto-Sensors Company. The Company competes primarily in
    each of the photonics market segments on the basis of technical
    suitability, product performance, reliability, and price.

        (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 employed 243 people.

    (d) Financial Information About Exports by Domestic Operations and About
        Foreign Operations

                    Report of Independent Public Accountants

    To the Shareholders and Board of Directors of Thermo Vision Corporation:

        We have audited, in accordance with generally accepted auditing
    standards, the consolidated financial statements included in Thermo
    Vision Corporation's Annual Report to Shareholders incorporated by
    reference in this Form 10-K, and have issued our report thereon dated
    February 17, 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 11 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.

                                THE DISTRIBUTION

             4.1  The Distribution.

                  (a)  Prior to the Distribution Date, Optek shall
        deliver to Vision the certificates for the approximate 6,783,800
        shares of Vision Common Stock owned by Optek, and Vision shall
        cancel such certificates.  In exchange therefor, and upon receipt
        from the Agent of a certificate as to the number of shares of
        Optek Common Stock outstanding as of the Distribution Record
        Date, Vision shall deliver to the Agent on the Distribution Date
        on behalf of Optek and for the benefit of the holders of record
        of Optek Common Stock as of the Distribution Record Date, an
        omnibus stock certificate representing in the aggregate 14 shares
        of Vision Common Stock for every 100 shares of Optek Common Stock
        outstanding as of the Distribution Record Date. Effective as of

        omnibus stock certificate to the Agent, ownership of the Vision
        Common Stock held by Optek shall pass to Optek's stockholders.
        Optek shall instruct the Agent to distribute, beginning on or
        promptly following the Distribution Date, to such holders of
        Optek Common Stock on the Distribution Record Date, certificates
        representing 14 shares of Vision Common Stock for every 100
        shares of Optek Common Stock outstanding as of the Distribution
        Record Date.  Vision agrees to provide to the Agent sufficient
        certificates in such denominations as the Agent may request in
        order to effect the Distribution.  All of the shares of Vision
        Common Stock issued in the Distribution shall be fully paid,
        nonassessable and free of preemptive rights.  In addition, all
        such shares (other than fractional shares sold by the Agent in
        accordance with Section 4.1(b) below) shall be subject to the
        Charter Transfer Restriction.  Holders of Optek Common Stock
        shall not be required to pay cash or other consideration for the
PAGE
<PAGE>
        Vision Common Stock received in the Distribution.

                  (b)  No fractional shares of Vision Common Stock will
        be received by Optek stockholders.  Fractional shares, if any,
        will be aggregated and sold, on behalf of the stockholders
        entitled to receive such shares, by the Agent.  The Agent will
        use the net proceeds from the sale of fractional shares to make
        cash payments to those stockholders otherwise entitled to receive
        fractional shares in proportion to their respective interests in
        such fractional shares.

                  (c)  The Distribution shall not be effected unless
        immediately thereafter the IPO is consummated.

        discretion and in accordance with all applicable rules of the
        American Stock Exchange, the Distribution Record Date, the
        Distribution Date, the date on which certificates representing
        Vision Common Stock shall be mailed to holders of Optek Common
        Stock and all appropriate procedures in connection with the
        Distribution.

                  (b)  In its sole discretion for any reason, the Optek
        Board may rescind the declaration of the Distribution, and after
        the declaration and until the Distribution Date, the Optek Board
        may postpone, withdraw, cancel or abandon the Distribution for
        any reason and simultaneously terminate this Agreement and the
        Ancillary Agreements.

        circumstances occurring or existing, or whether such
        Indemnifiable Losses are asserted, before or after the
        Distribution Date; (2) all Indemnifiable Losses incurred by
        Vision as a consequence of any misstatement or omission of a
        material fact with respect to Optek based on information supplied
        by Optek in any documents or filings prepared for purposes of
        compliance or qualification under applicable securities laws in
        connection with the Distribution, and related transactions,
        including without limitation, the Information Statement and the
PAGE
<PAGE>
        Form 10; and (3) all Indemnifiable Losses arising from any breach
        of or failure toperform any obligation on the part of any member
        of Optek Group contained in this Agreement or any of the
        Ancillary Agreements.  

                  (b)  Except as specifically otherwise provided in the
        Ancillary Agreements, Vision shall indemnify, defend and hold
        harmless the Optek Indemnitees from and against (1) all
        Indemnifiable Losses arising from or relating to the Vision
        Business, whether such Indemnifiable Losses relate to events,
        occurrences or circumstances occurring or existing, or whether
        such Indemnifiable Losses are asserted, before or after the
        Distribution Date; (2) all Indemnifiable Losses incurred by Optek
        as a consequence of any misstatement or omission of a material
        fact with respect to Vision based on information supplied by
        Vision in any documents or filings prepared for purposes of
        compliance or qualification under applicable securities laws in
        connection with the Distribution and related transactions,
        including without limitation, the Information Statement and the
        Form 10; and (3) all Indemnifiable Losses arising from any breach
        of or failure to perform any obligation on the part of any member
        of the Vision Group contained in this Agreement or any of the
        Ancillary Agreements.

                  (c)  If any Indemnifiable Loss arises from or relates
        to both the Optek Business and the Vision Business, Optek shall
        indemnify the Vision Indemnitees against any portion of such
        Indemnifiable Loss that pertains more directly to the Optek
        Business than to the Vision Business, and Vision shall indemnify
        the Optek Indemnitees against any portion of such Indemnifiable
        Loss that pertains more directly to the Vision Business than to
        the Optek Business.

                  (d)  Notwithstanding anything to the contrary set forth
        herein, indemnification relating to any arrangements between any
        member of the Optek Group and any member of the Vision Group (or
        any unit of the Vision Business) for the provision after the
        Distribution of goods and services in the ordinary course shall
        be governed by the terms of such arrangements and not by this
        Section.

             5.3  Procedures for Indemnification for Third-Party Claims.
        (a) Vision shall, and shall cause the other Vision Indemnitees
        to, notify Optek in writing promptly after learning of any
        Third-Party Claim for which any Vision Indemnitee intends to seek
        indemnification from Optek under this Agreement.  Optek shall,
        and shall cause the other Optek Indemnitees to, notify Vision in
        writing promptly after learning of any Third-Party Claim for
        which any Optek Indemnitee intends to seek indemnification from
        Vision under this Agreement.  The failure of any Indemnitee to
        give such notice shall not relieve any Indemnifying Party of its
        obligations under this Article V except to the extent that such
        Indemnifying Party or its Affiliate is actually prejudiced by
        such failure to give notice.  Such notice shall describe such
PAGE
<PAGE>
        Third-Party Claim in reasonable detail considering the 
        information provided to the Indemnitee.

                  (b)  Except as otherwise provided in subsection (c) of
        this Section, an Indemnifying Party may, by notice to the
        Indemnitee and to Vision, if Optek is the Indemnifying Party, or
        to Optek, if Vision is the Indemnifying Party, at any time after
        receipt by such Indemnifying Party of such Indemnitee's notice of
        a Third-Party Claim, undertake (itself or through another member
        of its Group) the defense or settlement of such Third-Party
        Claim.  If an Indemnifying Party undertakes the defense of any
        Third-Party Claim, such Indemnifying Party shall thereby admit
        its obligation to indemnify the Indemnitee against such
        Third-Party Claim, and such Indemnifying Party shall control the
        investigation and defense or settlement thereof, except that such
        Indemnifying Party shall not require any Indemnitee, without its
        prior written consent, to take or refrain from taking any action
        in connection with such Third-Party Claim, or make any public
        statement, which such Indemnitee reasonably considers to be
        against its interest, nor shall the Indemnifying Party, without
        the prior written consent of the Indemnitee and of Vision, if the
        Indemnitee is a Vision Indemnitee, or of Optek, if the Indemnitee
        is an Optek Indemnitee, consent to any settlement that does not
        include as a part thereof an unconditional release of the
        Indemnitees from liability with respect to such Third-Party Claim
        or that requires the Indemnitee or any of its Representatives or
        Affiliates to make any payment that is not fully indemnified
        under this Agreement or to submit to any non-monetary remedy; and
        subject to the Indemnifying Party's control rights, as specified
        herein, the Indemnitees may participate in such investigation and
        defense, at their own expense.

                  (c)  With respect to any Third-Party Claim, if there is
        a material conflict of interest between the Indemnifying Party
        and the Indemnitees involved, neither the Indemnifying Party nor
        the Indemnitees shall be entitled to control the defense or
        settlement thereof.  If an Indemnitee notifies an Indemnifying
        Party of Third-Party Claim pursuant to this Article V, and the
        Indemnifying Party does not take control of the defense or
        settlement thereof, or prior to the time that it does so take
        control, neither the Indemnifying Party nor the Indemnitees shall
        be entitled to control the defense or settlement thereof.  In any
        such event, the Indemnifying Parties and the Indemnitees involved
        shall each be entitled to conduct their own investigation and
        defense, but the parties shall cooperate to conduct such
        investigation and defense as efficiently as possible.  No
        Indemnitee may compromise or settle any Third-Party Claim
        described in this subsection as to which indemnification from an
        Indemnifying Party has or will be sought under this Agreement
        without the prior written consent of such Indemnifying Party.

                  (d)  If an Indemnifying Party is required to indemnify
        any Indemnitees with respect to a Third-Party Claim described in
        subsection (c) of this Section 5.3, such Indemnifying Party shall
PAGE
<PAGE>
        pay the reasonable attorneys' fees and expenses of one law firm 
        representing the Indemnitees involved in each jurisdiction with
        respect thereto.

                  (e)  Vision shall, and shall cause the other Vision
        Indemnitees to, and Optek shall, and shall cause the other Optek
        Indemnitees to, make available to each other, their counsel and
        other Representatives, all information and documents reasonably
        available to them which relate to any Third-Party Claim, and
        otherwise cooperate as may reasonably be required in connection
        with the investigation, defense and settlement thereof.

             5.4  Remedies Cumulative.  The remedies provided in this
        Article VI shall be cumulative and shall not preclude assertion
        by any Indemnitee of any other rights or the seeking of any other
        remedies against any Indemnifying Party.  However, the procedures
        set forth in Section 5.3 shall be the exclusive procedures
        governing any indemnity action brought under this Agreement or
        otherwise and relating to a Third-Party Claim, except as
        otherwise specifically provided in any of the Ancillary
        Agreements.

                                   ARTICLE VI

                              ADDITIONAL ASSURANCES

             6.1  Mutual Assurances.  Optek and Vision agree to cooperate
        with respect to the implementation of this Agreement and the
        Ancillary Agreements and to execute such further documents and
        instruments as may be necessary to confirm the transactions
        contemplated hereby.  Such cooperation may include joint meetings
        with corporate partners, suppliers, customers and others to
        assure the orderly transition of the business and assets
        contemplated hereby; provided, however, that nothing herein shall
        be deemed to obligate either Optek or Vision to take any action
        or reach any understandings which may violate any applicable
        laws.  Optek and Vision agree that they will not take any action
        inconsistent with the facts and representations set forth in the
        "no-action letter" request filed with the Commission in
        connection with the Distribution and will use their best efforts
        to cause such facts to remain true and correct and, if either
        Optek or Vision shall take any such inconsistent action, or fail
        to use such best efforts, it will indemnify the other party for
        any expense or Liability incurred as a consequence thereof.
        Optek and Vision also agree that the Distribution is intended to
        qualify under Section 355 of the Code, and that the
        characterization of the transactions contemplated hereunder for
        tax purposes and the liability of the parties for taxes shall be
        governed by the Tax Matters Agreement.  Except as otherwise
        specifically provided herein or as agreed between the parties
        from time to time, Optek and Vision shall bear their own expenses
        associated with the Distribution.  

                                   ARTICLE VII

             7.8  Material Changes.  No material adverse change shall
        have occurred with respect to Optek or Vision, the securities

                                  ARTICLE VIII

                       ACCESS TO INFORMATION AND SERVICES

             8.1  Provision of Corporate Records.  Upon Vision's request,
        Optek shall arrange as soon as practicable following the
        Distribution Date for the delivery to Vision of existing
        corporate records in the possession of Optek relating to the
        business and assets to be transferred to Vision, together with
        all active agreements and any active litigation files relating to
        the business, except to the extent such items are already in the
        possession of Vision.  Such records shall be the property of
        Vision but shall be available to Optek for review and duplication
        until Optek shall notify Vision in writing that such records are
        no longer of use to Optek.

             8.2  Access to Information.  From and after the Distribution
        Date, Optek shall afford to Vision and its authorized
        accountants, counsel and other designated representatives
        reasonable access (including using reasonable efforts to give
        access to persons or firms possessing information) and
        duplicating rights during normal business hours to all records,
        books, contracts, instruments, computer data and other data and
        information (collectively, "Information") within Optek's
        possession relating to Vision's business, insofar as such access
        is reasonably required by Vision.  Vision shall afford to Optek
        and its authorized accountants, counsel and other designated
        representatives reasonable access (including using reasonable
        efforts to give access to persons or firms possessing
        Information) and duplicating rights during normal business hours
        to Information within Vision's possession relating to Optek's
        business as constituted after the Distribution, insofar as such
        access is reasonably required by Optek.  Information may be
        requested under this Article VIII for, without limitation, audit,
        accounting, claims, litigation and tax purposes, as well as for
        purposes of fulfilling disclosure and reporting obligations and
        for performing the transactions contemplated in this Agreement
        and the Ancillary Agreements.

             8.3  Production of Witnesses.  At all times from and after
        the Distribution Date, each of Optek and Vision shall use
        reasonable efforts to make available to the other, upon written
        request, its officers, directors, employees and agents as
        witnesses to the extent that such persons may reasonably be
        required in connection with legal, administrative or other
        proceedings in which the requesting party may from time to time
        be involved.  

             8.4  Reimbursement.  Except to the extent otherwise
        contemplated by any Ancillary Agreement, a party providing
        Information to the other party under this Article VIII shall be
        entitled to receive from the recipient, upon the presentation of
        invoices therefor, payments for such amounts, relating to
        supplies, disbursements and other out-of-pocket expenses, as may
        be reasonably incurred in providing such Information.  

             8.5  Retention of Records.  For a period of seven (7) years
        following the Distribution Date, each of Optek and Vision shall
PAGE
<PAGE>
        retain all Information relating to the other, except as otherwise
        required by law or set forth in an Ancillary Agreement or except
        to the extent that such Information is in the public domain or in
        the possession of the other party; provided, that, after the
        expiration of such retention period, such Information shall not
        be destroyed or otherwise disposed of at any time, unless, prior
        to such destruction or disposal, (i) the party proposing to
        destroy or otherwise dispose of such Information shall provide no
        less than ninety (90) days' prior written notice to the other,
        specifying in reasonable detail the Information proposed to be
        destroyed or disposed of and (ii) if a recipient of such notice
        shall request in writing prior to the scheduled date for such
        destruction or disposal that any of the Information proposed to
        be destroyed or disposed of be delivered to such requesting
        party, the party proposing the destruction or disposal shall
        promptly arrange for the delivery of such of the Information as
        was requested, at the expense of the party requesting such
        Information.  

             8.6  Confidentiality.  Subject to any contrary requirement
        of law and the right of each party to enforce its rights
        hereunder in any legal action, each party shall keep strictly
        confidential, and shall cause its employees and agents to keep
        strictly confidential, any Information of or concerning the other
        party which it or any of its agents or employees may acquire
        pursuant to, or in the course of performing its obligations
        under, any provisions of this Agreement or any Ancillary
        Agreement; provided, however, that such obligation to maintain
        confidentiality shall not apply to Information which: (i) at the
        time of disclosure was in the public domain, not as a result of
        improper acts by the receiving party; (ii) was already
        independently in the possession of the receiving party at the
        time of disclosure; or (iii) is received by the receiving party
        from a third party who did not receive such Information from the
        disclosing party under an obligation of confidentiality.

                                   ARTICLE IX

                                    COVENANTS

             9.1  Listing.  Vision hereby agrees to use its reasonable
        efforts to effect and maintain the listing of the Vision Common
        Stock on the American Stock Exchange.

             9.2  Ancillary Agreements.  The parties agree that they
        shall comply with and provide all services and take any and all
        actions required to be provided or taken by the terms of any and
        all of the Ancillary Agreements following the Distribution.

PAGE
<PAGE>
        that, prior to the date of this Agreement, it has had primary 
        responsibility for the operation and management of the Vision
        Business and Optek acknowledges that, prior to the date of this
        Agreement, it has had primary responsibility for the operation
        and management of the Optek Business. Vision understands and
        agrees that no member of the Optek Group is, in this Agreement or
        in any other agreement or document, representing or warranting to
        Vision or any member of the Vision Group in any way as to the
        Vision Assets, the Vision Business or the Liabilities of the
        Vision Group or as to any consents or approvals required in
        connection with the consummation of the transactions contemplated
        by this Agreement, it being agreed and understood that Vision and
        each member of the Vision group shall bear the economic and legal
        risk that conveyances of the Vision Assets shall prove to be
        insufficient, that the title of any member of the Vision group to
        any Vision Assets shall be other than good and marketable and
        free from encumbrances or that results from the failure of Vision
        or any member of the Vision Group to obtain any consents or
        approvals relating to the Vision Business required in connection
        with the consummation of the transactions contemplated by this
        Agreement.

        this Article XI shall apply to each agreement constituting an
        Ancillary Agreement or to which reference is made herein.

        modified only in writing executed on behalf of Optek and Vision.

        an annual  fixed fee  equal  to 1.0%  of  the gross  revenues  of
        Subsidiary for  the  fiscal  year  in  which  such  services  are
        performed (such amount to  be prorated on a  daily basis for  any
        partial year), which  fee is  intended to  compensate Thermo  for
        Subsidiary's pro  rata  share  of the  aggregate  costs  actually
        incurred by  Thermo  in connection  with  the provision  of  such
        services to all  recipients thereof.   The fee set  forth in  the

        in Thermo's judgment, are not routine administrative services  or

        (including legal  services),  corporate  development,  tax  audit
        support or  public  or  investor relations  services  other  than
        routine  shareholder   communications.     Thermo   will   charge
        Subsidiary the costs actually  incurred  (including overhead  and
        general administrative  expenses)  for  such  services  that  are
        requested by Subsidiary and supplied by Thermo.

             1.4  The charges for  services pursuant  to Subsections  1.2
        and 1.3 above will be  determined and payable no less  frequently

                                        2PAGE

        than on a quarterly basis.   The charges will be due when  billed
        and shall be paid no later than 30 days from the date of billing.

             1.5  When services  of  the  type described  above  in  this
        Section 1 are provided by outside providers to Subsidiary or,  in
        connection with  the  provision of  such  services  out-of-pocket
        costs are incurred such as travel, the cost thereof will be  paid
        by Subsidiary.  To  the extent that Subsidiary  is billed by  the
        provider directly, Subsidiary  shall pay the  bill directly.   If
        Thermo is billed for such services,  Thermo may pay the bill  and
        charge Subsidiary the amount of the  bill or forward the bill  to
        Subsidiary for payment by Subsidiary.



             2.   Subsidiary's Directors and Officers.  Nothing contained
        herein will be construed to relieve the directors or officers  of
        Subsidiary from the performance of their respective duties or  to

        judgment or for anything except willful malfeasance, bad faith or
        gross negligence in the performance  of their duties or  reckless
        disregard of their obligations and duties under the terms of this
        Agreement.  The  provisions of  this Agreement are  for the  sole
        benefit of  Thermo and  Subsidiary and  will not,  except to  the

        administration of employee benefit  plans and insurance  programs
        sponsored  by  Thermo   and  in   which  Subsidiary's   employees
        participate) or as  otherwise required  by Thermo   acting in its
        capacity as majority  stockholder of  Subsidiary.   In the  event
        such services are  provided by Thermo  to Subsidiary,  Subsidiary

        other services  to  other companies  that  may or  may  not  have
        policies and conduct activities  similar to those of  Subsidiary.

        required to devote full time and attention to the performance  of
        its duties under this Agreement, but shall devote only so much of

                            TAX ALLOCATION AGREEMENT


             THIS AGREEMENT is  made as  of November  14th, 1997  between
        Thermo Electron Corporation , a Delaware corporation ("TMO "), and
        Thermo Vision Corporation, a Delaware corporation ("Vision" - The
        term "Vision" shall refer to Vision and those of its subsidiaries
        that are  members of an affiliate group of  corporations including
        Vision within  the meaning  of Section  1504(a) of  the  Internal
        Revenue Code of 1986, as amended (the "Code")).


                              Preliminary Statement

             TMO is the parent of an affiliate group of corporations
        (including Vision) within the meaning of Section 1504(a) of the
        Code (the "Thermo Group").  The Thermo Group has elected to file
        a consolidated return for federal income tax purposes.

             By this  Agreement,  the parties  desire  to set  forth  the
        understanding they have reached with respect to the filing of the
        consolidated United States federal  income tax returns and  state
        income tax returns. Foreign tax  returns are not subject to  this
        Agreement.


                                   Agreements

             IT IS MUTUALLY agreed by the parties hereto as follows:

             1.   Definitions and Construction.

                  1.1. The  Term   "TMO  Group"   means  the   group   of
        corporations of which  TMO is  common parent and  with which  TMO
        files an  affiliated  consolidated  federal  income  tax  return,
        excluding Vision and subsidiaries of Vision that may exist now or
        in the future.   For purposes  of this Agreement,  the TMO  Group
        shall be treated as a single corporate entity.  The TMO Group and
        Vision and its subsidiaries,  respectively, are sometimes  herein
        referred  to  collectively   as  the  "Two   Companies"  or   the
        "Companies."  This Agreement anticipates that TMO will set  aside
        and retain  certain  sums calculated  as  provided herein.    All
        reference to TMO paying sums to itself pursuant to this Agreement
        shall be satisfied by  TMO setting aside sums  in respect of  the
        obligations established under this Agreement.

                  1.2. The  paragraph   titles   used  herein   are   for
        convenience of reference only and  will not be considered in  the

        Words may  be construed  in the  singular or  the plural  as  the
        context requires.

             2.   Tax Returns.

                  2.1. Federal Tax  Returns.   TMO as  the common  parent
        will prepare and file or cause  to be prepared and filed  federal
        income tax returns on a consolidated basis, for the TMO Group and

        consolidated return is appropriate  in accordance with the  terms
        of this Agreement.

                  2.2. State Tax Returns .  TMO as the common parent will
        prepare and file or cause to be filed state income tax returns on
        a combined,  consolidated,  unitary,  or other  method  that  TMO
        believes will result in a lower overall tax liability to the  Two
        Companies.   In the event  that said state  tax returns shall  be
        filed, the  provisions  of sections  1  through 11  hereof  shall
        apply, mutatis mutandis (the necessary changes being made) to the
        allocation, preparation, filing and payment related to such state
        taxes and tax returns.  Vision will  reimburse TMO   for Vision's
        portion of the tax.   Such reimbursement will  be the tax  Vision
        would have paid on  a separate return basis,  but only if it  was
        required to file a return in that state.

             3.   Time of Payment  of Federal  Obligations to  TMO .  The
        obligations of the Companies for Federal income tax payments will
        be determined and paid as follows:

                  (a)  Not later than the 15th  day after the end of  the
        fourth, sixth,  ninth and  twelfth  months of  each  consolidated
        taxable year of  TMO, TMO  will make  a reasonable  determination
        (consistent with the provisions of  Section 6655 of the Code)  of
        the separate federal income tax liability that each Company would
        be required to  pay as  estimated payments on  a separate  return
        basis for that period. Each Company  shall pay to TMO the  amount
        of such liability within ten days.

                  (b)  After the end of  TMO's  fourth accounting quarter
        and before  the 15th  day  of the  third month  thereafter,  each
        Company will promptly pay to TMO the entire amounts estimated  to
        be due and payable under such Company's federal income tax return
        as if  filed  on  a  separate  return  basis,  less  all  amounts
        previously  paid   with  respect   to  that   year  pursuant   to
        subparagraph (a) of this Paragraph 3.

                  (c)  If upon the filing of the consolidated income  tax
        return, a revised calculation is made in the manner set forth  in
        subparagraph (b) of this Paragraph  3, and it is determined  that
        either Company has paid to  TMO with respect to the  consolidated
        taxable year an  amount greater than  that required by  Paragraph
        3(b), then  that excess  will be  promptly paid  by TMO  to  that
        Company.

                                          2PAGE
<PAGE>
             4.   Tax Obligations of TMO .  TMO will pay the consolidated
        tax  liabilities  of   the  Companies  arising   from  filing   a
        consolidated federal income tax return.

             5.   Payment of Funds by TMO.  After the end of TMO's fourth
        quarter and before the 15th day of the third month thereafter, if
        in any year Vision incurs a loss,  TMO shall pay to Vision a  sum
        equal to the  amount of benefit  realized by members  of the  TMO
        Group (other  than  Vision)  that is  attributable  to  the  loss
        incurred by Vision.

             6.   Changes in Prior Year's Tax Liabilities .  In the event
        that the consolidated tax liability or the separate tax liability
        referred to in  Paragraphs 3,  4 and 5  hereof for  any year  for
        which a consolidated tax return  for the two Companies was  filed
        is or would  be increased  or decreased  by reason  of filing  an
        amended return or  returns (including carry-back  claims), or  by
        reason of the examination of the returns by the Internal  Revenue
        Service, the amounts of payments under  Paragraphs 3, 4 or 5,  as
        the case may be,  for each such year will be recomputed by TMO to
        reflect the adjustments to taxable income and tax credits for the
        taxable year and interest  or penalties, if  any.  In  accordance
        with those recomputations,  additional sums will  be  paid by the
        Companies to TMO or  paid by TMO to  the Companies regardless  of
        whether a member  has become  a Departing Member  (as defined  in
        Paragraph  8   hereof)  subsequent   to  the   taxable  year   of
        recomputation.

             7.   New Members  . The Companies  agree that if, subsequent
        to the execution of  this Agreement, TMO  becomes the parent,  as
        that term is used  in Section 1504  of the Code,  of one or  more
        subsidiary corporations, in addition  to Vision, then each  newly
        acquired subsidiary corporation  may become a  separate party  to
        this Agreement  by  consenting in  writing  to be  bound  by  its
        provisions, effective immediately upon  its delivery to TMO,  but
        the income,  deductions and  tax credits  of the  newly  acquired
        subsidiary  corporations   will   first  be   included   in   the
        consolidated federal income tax return as required by the Code.

             8.   Departing Members.

                  8.1. The term "Departing Member," as used herein,  will
        mean a Company that is no  longer permitted under the Code to  be
        included in the consolidated federal income tax return.

                  8.2. In applying this Agreement  to a Departing  Member
        for the final taxable year  in which its income, deductions,  and
        tax credits  are  required to  be  included in  the  consolidated
        federal income tax return:  (i) the amount required to be paid by
        a Departing Member under the provisions of Paragraph 3 hereof and
        (ii) the amount that the Departing Member is entitled to  receive
        under the provisions of Paragraph 4 hereof, will be determined by

                                          3PAGE
<PAGE>
        taking into account the income, deductions and tax credits of the
        Departing Member only for the fractional part of such year as the
        Departing Member  was  a member  of  the consolidated  group  and
        included in the consolidated federal income tax return.

                  8.3. After  the  filing  of  the  consolidated  federal
        income tax return for  the last taxable  year that the  Departing
        Member  was  included  therein,  the  Departing  Member  will  be
        informed of the amount of consolidated carry-overs as of the  end
        of the  taxable year  or  period which  are attributable  to  the
        Departing Member,  as provided  by Treasury  Regulations  Section
        1.1502-79 or otherwise, including the agreement of the parties.

             9.   Determination of Sums Due from and Payable to  Members.
        TMO will determine the sums due from and payable to the Companies
        under  the   provisions   of  this   Agreement   (including   the
        determination for purposes of Paragraph 6 hereof).  The Companies
        agree to provide TMO with  such information as may reasonably  be
        necessary to make  these determinations.   Issues arising in  the
        course of the  determinations that are not expressly provided for
        in this Agreement will be resolved in an equitable manner.

             10.  Tax Controversies .  If  a consolidated  federal income
        tax return for any taxable year during which this Agreement is in
        effect  is  examined  by   the  Internal  Revenue  Service,   the
        examination, as well as  any other matters  relating to that  tax
        return, including any tax litigation,  will be handled solely  by
        TMO.  Vision will cooperate with TMO and to this end will execute
        protests, petitions, and any other documents as TMO determines to
        be necessary  or appropriate.    The cost  and expense  of  TMO's
        handling of  a tax  controversy, including  legal and  accounting
        fees, will be allocated  to and paid by  the Company to whom  the
        tax controversy relates.  If the tax controversy relates to  both
        Companies, the cost  and expense  will be  allocated between  the
        Companies  in  the  proportion  that  each  Company's   potential
        additional tax liability bears to the total potential  additional
        tax liability of  both Companies (determined  in accordance  with
        Paragraph 6  hereto  and assuming  that  the tax  controversy  is
        resolved in  favor  of  the Internal  Revenue  Service)  for  the
        taxable year on issue.   If the tax controversy encompasses  more
        than one  taxable year,  TMO  will first  allocate the  cost  and
        expense to each taxable year in the proportion that the potential
        additional tax liability for each taxable year bears to the total
        potential additional  tax  liability  for the  taxable  years  in
        issue.

             11.  Effective Date .  This  Agreement shall  be  effective
        beginning as of the date of this Agreement, and will continue  on
        a year-to-year basis  thereafter with  respect to  Vision for  so
        long as Vision is permitted to file a consolidated federal income
        tax return with TMO.

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

        shall provide Buyer with a complete list of  Purchased Securities
        owned by Buyer.  

             (c)  Upon demand by Buyer or Seller, Seller shall repurchase
        from Buyer, and Buyer shall  sell to Seller,  for  the Repurchase
        Price all or any part  of the Purchased Securities then  owned by

        4.   Margin Maintenance

                                        2PAGE
<PAGE>
             (a)  If at  any  time  the  aggregate Market  Value  of  all
        Purchased Securities then owned by Buyer is less than 103% of the
        aggregate Repurchase Price  for such  Purchased Securities,  then
        Seller shall transfer to Buyer additional Securities ("Additional
        Purchased Securities"),  so that  the aggregate  Market Value  of
        such  Purchased   Securities,  including   any  such   Additional
        Purchased Securities, will  thereupon equal  or exceed   103%  of
        such aggregate Repurchase Price.

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

        5.   Interest Payments

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

        6.   Income Payments and Voting Rights

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

        7.   Security Interest

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

        8.   Payment and Transfer

             Unless otherwise  mutually agreed,  all  transfers of  funds
        hereunder shall  be  in immediately  available  funds.   As  used
        herein with respect to Securities, "transfer" is intended to have

                                        3PAGE
<PAGE>
        the  same  meaning  as  when   used  in  Section  8-313   of  the
        Massachusetts Uniform Commercial  Code or,  where applicable,  in
        any federal regulation governing transfers of the Securities.

        9.   Substitution

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

        10.  Representations

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

        11.  Events of Default

             In the event that  (i) Seller fails  to repurchase or  Buyer
        fails to transfer Purchased Securities upon demand for repurchase
        from either Buyer or Seller,  (ii)  Seller or Buyer  fails, after
        one business day's  notice, to  comply with  Paragraph 4  hereof,

        Paragraph 6 hereof, (iv) Seller fails to comply  with Paragraph 5

        Seller or Buyer shall admit to the other its inability to, or its

                                        4PAGE

        intention not to, perform any of its obligations  hereunder (each
        an "Event of Default"):

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

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

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

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

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

                  (ii)    as  to  Transactions  in  which  Buyer  is  the
        defaulting   party,   (A)   purchase   securities   ("Replacement
        Securities") of  the  same  class  and amount  as  any  Purchased
        Securities that are not delivered by Buyer to  Seller as required

                                        5PAGE
<PAGE>
        hereunder or  (B)  in  its  sole discretion  elect,  in  lieu  of
        purchasing Replacement Securities, to be deemed to have purchased
        Replacement Securities  at  the  price  therefor  on  such  date,
        obtained from a  generally recognized source  or the most  recent
        closing bid quotation from such a source.

             (e)  As to  Transactions in  which Buyer  is the  defaulting
        party ,  Buyer shall  be liable  to Seller  (i)  with respect  to
        Purchased   Securities   (other    than   Additional    Purchased
        Securities), for any excess of the price paid (or deemed paid) by
        Seller for Replacement  Securities therefor  over the  Repurchase
        Price for  such Purchased  Securities and  (ii)  with respect  to
        Additional Purchased Securities,  for the  price paid (or  deemed
        paid) by Seller for the Replacement Securities therefor.  

             (f)  The  defaulting   party   shall   be  liable   to   the
        nondefaulting party for  the amount  of all  reasonable legal  or
        other expenses incurred by the nondefaulting party  in connection
        with or as a consequence of an Event of Default.

             (g)  The nondefaulting party shall have, in addition  to its
        rights hereunder, any rights otherwise available to it  under any
        other agreement or applicable law.

        12.  Single Agreement

             Buyer and Seller acknowledge that, and have entered hereinto
        and will enter into  each Transaction hereunder in  consideration
        of and in reliance upon the fact that, all Transactions hereunder
        constitute a  single business  and  contractual relationship  and
        have been made in consideration of each other.  Accordingly, each
        of Buyer and Seller agrees (i) to perform all  of its obligations
        in respect of each Transaction  hereunder, and that a  default in
        the performance  of  any  such  obligations  shall  constitute  a
        default by it in respect of all Transactions hereunder, (ii) that
        each of  them shall  be  entitled to  set  off claims  and  apply
        property held  by  them in  respect  of any  Transaction  against
        obligations owing to  them in respect  of any other  Transactions
        hereunder and (iii) that payments, deliveries and other transfers
         made by either  of them in respect  of any Transaction shall  be
        deemed to have been made in consideration of payments, deliveries
        and  other  transfers  in  respect  of  any   other  Transactions
        hereunder,  and  the  obligations  to  make  any  such  payments,
        deliveries and other transfers may be applied against  each other
        and netted.

        13.  Entire Agreement; Severability

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

                                        6PAGE
<PAGE>
        enforceable notwithstanding  the  unenforceability  of  any  such
        other provision or agreement.

        14.  Non-assignability; Termination

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

        15.  Governing Law

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

        16.  No Waivers, Etc.

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

        19.  Intent

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

             (b)  It is understood that either party's right to liquidate
        Securities  delivered  to  it  in  connection  with  Transactions
        hereunder or to exercise any other remedies pursuant to Paragraph
        11 hereof, is a  contractual right to liquidate  such Transaction
        as described in Sections  555 and 559 of  Title 11 of the  United
        States Code, as amended.

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

                         MASTER GUARANTEE REIMBURSEMENT
                               AND LOAN AGREEMENT


             This AGREEMENT  is  entered  into  as of  the  24th day  of
        November, 1997  by and among Thermo Instrument  Systems 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
        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
PAGE
<PAGE>
             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 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 subsidiarie s.  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 subsidiarie   s 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
PAGE
<PAGE>
             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.  

        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 subsidiarie s, 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
PAGE
<PAGE>
             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

                              CID SUPPLY AGREEMENT


             THIS CID SUPPLY AGREEMENT, effective as of the 15th day of
        December, 1997 (the "Effective Date"), is between THERMO VISION
        CORPORATION, a Delaware corporation having offices at 8E Forge
        Parkway, Franklin, Massachusetts 02038, Telecopy No. 508-553-1742

        corporation having offices at 8E Forge Parkway, Franklin,
        Massachusetts 02038, Telecopy No. 508-541-0140 ("Thermo Optek")
        regarding the supply by Thermo Vision of certain products to be
        purchased by Thermo Optek and its affiliates.

             NOW, THEREFORE, in consideration of the mutual promises,
        terms and conditions hereinafter set forth, and other good and
        valuable consideration, the receipt and sufficiency of which are
        hereby acknowledged, Thermo Vision and Thermo Optek (the
        "Parties") do hereby agree as follows:

             For the purposes of this Agreement, an "Affiliate" of a
        Party means an individual or business entity controlling,
        controlled by or under common control with such Party, with
        control meaning a 50% or more ownership interest.

        1.   Thermo Vision's Supply of Products.

             (a)  Thermo Vision hereby agrees to sell the Products to
        Thermo Optek and its Affiliates, in accordance with the terms and
        conditions of this Agreement. Subject to Paragraph 1(g)(ii)
        hereof, Thermo Vision agrees not to sell the Products to any
        other party which manufactures optical spectrometers of the types
        manufactured by Thermo Optek.  "Products" means all charge
        injection devices ("CID") sensors manufactured by or on behalf of
        Thermo Vision for: 

                  (i)optical spectrometers, including without limitation
                  ICP, ICP-MS, AA and Arc-Spark; or 

                  (ii)raman spectrometers and other analytical
                  instruments, if after the Effective Date but during the
                  term of this Agreement Thermo Vision and Thermo Optek
                  (A) enter into a research, development and supply
                  agreement with respect to raman spectrometers or other
                  analytical instruments; and (B) agree on pricing for
                  such raman spectrometers or other analytical
                  instruments.

             (b)  The Products shall also be deemed to include any
        modifications or improvements to the CID sensors described above
        which Thermo Vision or asubsidiary of Thermo Vision may develop
        or manufacture, or cause to be developed or manufactured, during
        the term of this Agreement, provided, however, that all such
PAGE
<PAGE>
        modifications and improvements shall have been approved by Thermo
        Optek prior to inclusion in the CID sensors in order to insure
        compatibility with Thermo Optek applications.

             (c)  As soon as practicable after the Effective Date, Thermo
        Optek shall provide to Thermo Vision a non-binding forecast for
        the next 12 calendar months of the anticipated requirements of
        Thermo Optek and its Affiliates for the Products and indicating
        the likely delivery dates to be requested.  Thermo Optek shall
        update this forecast each calendar quarter on a rolling basis.  

             (d)  Thermo Optek and its Affiliates shall thereafter from
        time to time place firm orders with Thermo Vision at least 6
        months before the requested delivery date by the transmittal to
        Thermo Vision of written orders on Thermo Optek's regular
        purchase order forms, which shall be deemed accepted upon Thermo
        Vision's written acceptance thereof.  Such purchase orders shall
        identify  the Products ordered, the quantities ordered, requested
        delivery date(s) and any export information required to enable
        Thermo Vision to fill the order.

             (e)  Unless Thermo Optek or its Affiliate requests
        otherwise, all Products ordered shall be packed for shipment and
        storage in accordance with Thermo Vision's standard commercial
        practices.  It is the obligation of Thermo Optek or such
        Affiliate to notify Thermo Vision and obtain Thermo Vision's
        consent to any special packaging requirements (which shall be at
        the expense of Thermo Optek or such Affiliate).  The terms and
        conditions of this Paragraph 1(e) shall be reviewed by the
        Parties on an annual basis and are subject to change based on the
        mutual agreement of the Parties.

             (f)  In the event of any discrepancy between any purchase
        order and this Agreement, the terms of this Agreement shall
        govern.  

             (g)  During the term of this Agreement, Thermo Optek
        shall purchase all of its requirements of Products from Thermo
        Vision, and Thermo Optek shall cause all of its Affiliates to
        purchase all of their requirements of Products from Thermo
        Vision; provided, however that:

                  (i)  Thermo Optek and its Affiliates shall have the
        right to make a Product themselves (using their own or
        third-party technology) or purchase a Product from a third party,
        if:  (A) Thermo Vision does not accept a firm order placed by
        Thermo Optek or such Affiliate for such Product with a requested
        delivery date at least 6  months after the date on which Thermo
        Optek or such Affiliate placed such order; or (B) such Product
        previously delivered by Thermo Vision was repeatedly found not to
        conform to the agreed-upon specifications for such Product,or
        Thermo Vision repeatedly and materially failed to deliver such
        Product on or before the requested delivery dates (unless such
        failure is due to causes beyond Thermo Vision's control) and
PAGE
<PAGE>
                  (ii) Thermo Vision shall have the right to sell a
        Product to a third party for use in such third party's optical
        spectrometers, raman spectrometers or other analytical
        instruments (the "Third Party Instruments") if:  (A) as of the
        Effective Date hereof, Thermo Optek (1) is not using such Product
        in its optical spectrometers, raman spectrometers or other
        analytical instruments, respectively, which are similar to the
        Third Party Instruments, or (2) does not offer optical
        spectrometers, raman spectrometers or other analytical
        instruments, respectively, which are similar to the Third Party
        Instruments, (B) prior to the execution by Thermo Vision of an
        agreement to sell such Product to such third party (the "Third
        Party Agreement"), Thermo Vision provides written notice to
        Thermo Optek setting forth the material terms and conditions of
        the Third Party Agreement, including without limitation, the
        price per Product, the quantity of Product to be sold and the
        term of the Third Party Agreement (the "Third Party Notice") and
        (C) within 30 days after receipt by Thermo Optek of the Third
        Party Notice, Thermo Vision has not received from Thermo Optek
        Thermo Optek's written agreement to purchase such Product from
        Thermo Vision for use in Thermo Optek's optical spectrometers,
        raman spectrometers or other analytical instruments, as the case
        may be, on substantially the same terms as those contained in the
        Third Party Agreement.  By way of illustration and assuming all
        other conditions set forth in Paragraph 1(g)(ii) are satisfied,
        Thermo Vision shall be permitted to sell a Product to a third
        party for use in such third party's raman spectrometers if Thermo
        Optek purchases such Product from Thermo Vision solely for use in
        Thermo Optek's optical spectrometers and other analytical
        instruments.

        2.   Compensation for Supply.

             (a)  For each Product purchased by Thermo Optek or one of
        its Affiliates hereunder, Thermo Vision shall be paid the price
        indicated in Schedule A hereto.  The price of each such Product
        shall be reviewed by the Parties on an annual basis and is
        subject to adjustment based on the mutual agreement of the
        Parties.  With respect to modifications or improvements to CID
        sensors which are included in the definition of Products in
        accordance with Paragraph 1(b) above, Thermo Vision shall
        establish a price for each such new Product which is reasonable
        in light of the manufacturing cost and performance of such new
        Product relative to the most closely related existing Product.
        For each Product purchased by Affiliates of Thermo Optek
        hereunder, such Affiliates and Thermo Optek shall be jointly and
        severally liable for the payment of the price of such Product to
        Thermo Vision.

             (b)  Each payment for Products shall be made by check in
        good funds to the order of Thermo Vision or its Affiliates, and
        shall be delivered to Thermo Visionwithin thirty (30) days after
        the receipt by Thermo Optek or its respective Affiliate of Thermo
PAGE

        Thermo Vision's expenses therefor, the Products may be delivered
        to Thermo Vision's warehouse facility for storage.  Thermo Optek
        shall thereupon pay such storage and handling fees as are within
        the customary industry practice. 

             (c)  The terms and conditions of Paragraphs 3(a) and (b)
        shall be reviewed by the Parties on an annual basis and are
        subject to change based on the mutual agreement of the Parties.  

             (d)  Thermo Vision shall be responsible for preparing
        invoices and shipping documents for Thermo Optek or its
        respective Affiliate in respect of Products purchased hereunder;
        provided, however, that Thermo Vision shall submit its invoice
        for Products no earlier than the date on which Thermo Vision (i)
        makes such Products available to a common carrier for pick up at
        such Product's place of manufacture or (ii) delivers such
        Products to Thermo Vision's warehouse facility for storage

        delivered to Thermo Vision's warehouse facility for storage
        pursuant to the agreement of the Parties.  The terms and
        conditions of this Paragraph 4 shall be reviewed by the Parties
        on an annual basis and are subject to change based on the mutual
        agreement of the Parties.  

        5.   Force Majeure.  Except for obligations of payment, each
        Party shall be excused for any delay or failure to fulfill any of
        their respective obligations under thisAgreement if such failure

        Thermo Vision tenders such Products or delivers such Products to
        Thermo Vision's warehouse facility for storage pursuant to the
        agreement of the Parties, as the case may be.  The terms and
        conditions of this Paragraphs 6(a) shall be reviewed by the
        Parties on an annual basis and are subject to change based on the
        mutual agreement of the Parties.

        WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, WRITTEN OR
        ORAL, WITH RESPECT TO THE PRODUCTS, INCLUDING ALL WARRANTIES OF

        MANUFACTURE OR SALE OF THE PRODUCTS. 

        7.   Confidentiality.  Each Party acknowledges and agrees that in
        the course of its performance of this Agreement confidential
        technology, trade secrets or other proprietary information
        relating to the development, manufacture and sale of the Products
        (hereinafter "Confidential Information") may be made known or
        made available to the other party.  Accordingly, during and after
        the term of this Agreement, each Party hereby represents and
PAGE
<PAGE>
        agrees to the following:

             (a)  that each Party (the "disclosing Party") has a
        proprietary interest in its own Confidential Information.  During
        and after the term of this Agreement, all disclosures by the
        disclosing Party of its Confidential Information to the other
        Party (the "receiving Party"), its agents and employees shall be
        held in strict confidence by the receiving Party, which shall
        disclose such Confidential Information only to those of its
        agents and employees to whom it is necessary in order to properly
        carry out their duties as limited by the terms and conditions
        hereof.  During and after the term of this Agreement, the
        receiving Party shall not use the Confidential Information of the
        disclosing Party except for the purposes of the receiving Party
        exercising its rights and carrying out its duties hereunder.  The
        provision of this Paragraph 7 shall also apply to any
        sublicensees, consultants or subcontractors during and after the
        term of this Agreement, that the receiving Party may sublicense
        or engage in connection with this Agreement.  Each receiving
        Party shall take necessary steps to ensure that its employees
        respect the terms of this Paragraph 7.

             (b)  that notwithstanding anything contained in this
        Agreement to the contrary, the receiving Party shall not be
        liable for a disclosure of the disclosing Party's Confidential
        Information if the information so disclosed:

                  (i)  was in the public domain at the time it was
        disclosed by the disclosing Party to the receiving Party, or
        becomes part of the public domain thereafter through no fault of
        the receiving Party; or 

                  (ii) was known to or contained in the records of the
        receiving Party at the time of disclosure by the disclosing Party
        to the receiving Party and can be so demonstrated; or

                  (iii)     becomes known to the receiving Party from a
        source other than the disclosing Party without breach of such
        source's confidentiality obligation, if any, to the disclosing
        Party and can be so demonstrated; or

                  (iv) was required to be disclosed under legal or
        administrative process, provided that the receiving Party has
        given the disclosing Party no less than ten (10) days prior
        written notice of the receiving Party's intention to make a
        disclosure pursuant to this Paragraph 7(b)(iv).


        8.   Intellectual Property Warranty; Indemnification

             (a)  With respect to Paragraph 1(a)(ii) above, Thermo Optek
        represents and warrants to Thermo Vision that if CID sensors for
        raman spectrometers are added to the definition of Products,
        Thermo Optek shall have the full right to use under written
PAGE
<PAGE>
        agreements, all patents, copyrights, trademarks, trade secrets
        and other intellectual property rights (the "Intellectual
        Property Rights") which will be required in order to permit
        Thermo Vision to manufacture such Products.   Upon adding such
        sensors to the definition of Products, Thermo Optek shall grant
        Thermo Vision and its Affiliates and subcontractors a worldwide,
        exclusive, royalty-free license to use such Intellectual Property
        Rights during the term of this Agreement for the sole purpose of
        manufacturing such Products for sale to Thermo Optek and/or its
        Affiliates pursuant to this Agreement.

             (b)  Thermo Vision represents and warrants to Thermo Optek
        that it owns, or has the full right to use under written
        agreements, all Intellectual Property Rights which will be used
        or practiced in order for Thermo Vision to manufacture and sell
        the Products described in Paragraph 1(a)(i) above.  Thermo Vision
        has no knowledge of any infringement of any Intellectual Property
        Right of any third party which will arise out of or be incident
        to Thermo Vision's use of such Intellectual Property Rights to
        manufacture and sell such Products. 

             (c)  In the event of any claim, charge, suit or proceeding
        by any third party against either Party alleging infringement or
        violation of any Intellectual Property Rights pursuant to this
        Agreement, the other Party shall cooperate fully in the defense
        of any such claim, charge, suit or proceeding.  In the event that
        the actions of one Party shall be determined to have solely
        resulted in such allegation(s), that Party shall indemnify and
        hold the other Party harmless from and against any loss arising
        out of such claim, charge, suit or proceeding, not to exceed the
        amounts paid by the other Party to the such third party.

             (d)  Notwithstanding anything contained in this Paragraph 8
        to the contrary, neither Party (the "indemnifying Party") shall
        have any obligation to the other Party (the "indemnified Party")
        hereunder with respect to an infringement claim which arises
        from: (i) any combination by the indemnified Party or any of its
        Affiliates of the Products with another product not supplied by
        the indemnifying Party, where such infringement would not have
        occurred but for such combination; (ii) the adaptation or
        modification of the Products not performed by the indemnifying
        Party, where such infringement would not have occurred but for
        such adaptation or modification; (iii) the misuse of the Products
        or the use of the Products in an application for which it was not
        designed, where such infringement would not have occurred but for
        such use or misuse; or (iv) a claim based on intellectual
        property rights owned by the indemnified Party or any of its
        Affiliates.

        discharge shall be effective only in the specific instance and
        for the specific purpose for which given.  No provision of this
        Agreement shall be varied, contradicted or explained by any oral
        agreements, course of dealing or performance or any other matter
        not set forth in an agreement in writing and signed by both
        Parties.

        joint venture, agency, partnership or employer-employee
        relationship between the Parties hereto.  Neither Party shall

        fullest extent permitted by law:  (i) all other provisions hereof
        shall remain in full force and effect in such jurisdiction and
        shall be liberally construed in order to carry out the intentions
        of the Parties hereto as nearly as may be possible; and (ii) such
        invalidity, illegality or unenforceability shall not affect the
        validity, legality or enforceability of such provision in any
        other jurisdiction.  To the extent permitted by applicable law,
        each Party hereby waives any provision of law that would render
        any provision hereof prohibited or unenforceable in any respect.

             (h)  No failure on the part of either Party to exercise and
        no delay in exercising any right, power, remedy or privilege
        under this Agreement, or provided by statute or at law or in
        equity or otherwise, shall impair, prejudice or constitute a
        waiver of any such right, power, remedy or privilege or be
        construed as a waiver of any breach of this Agreement or as an
        acquiescence therein, nor shall any single or partial exercise of
        any such right, power, remedy or privilege preclude any other or
        further exercise thereof or the exercise of any other right,
        power, remedy or privilege.

             (i)  Notwithstanding anything else in this Agreement to the
        contrary, the Parties agree that Paragraphs 6, 7, 8, 10 and 11

                              EQUITY INCENTIVE PLAN
                              ---------------------


        1.   Purpose
             -------

             The purpose of this Equity Incentive Plan (the "Plan") is to
        secure for  Thermo Vision  Corporation  (the "Company")  and  its
        Stockholders the benefits arising from capital stock ownership by
        employees, officers  and Directors  of, and  consultants to,  the
        Company and its subsidiaries or other persons who are expected to
        make significant contributions to  the future growth and  success
        of the Company  and its subsidiaries.   The Plan  is intended  to
        accomplish these  goals by  enabling the  Company to  offer  such
        persons  equity-based  interests,   equity-based  incentives   or
        performance-based  stock  incentives  in  the  Company,  or   any
        combination thereof ("Awards").

        2.   Administration
             --------------

             The Plan will be administered  by the Board of Directors  of
        the Company (the "Board").   The Board shall  have full power  to
        interpret and  administer  the  Plan,  to  prescribe,  amend  and
        rescind rules and  regulations relating to  the Plan and  Awards,
        and full authority to select the  persons to whom Awards will  be
        granted ("Participants"), determine the type and amount of Awards
        to be  granted  to  Participants (including  any  combination  of
        Awards), determine  the terms  and conditions  of Awards  granted
        under the Plan (including terms and conditions relating to events
        of merger, consolidation, dissolution and liquidation, change  of
        control,  vesting,   forfeiture,  restrictions,   dividends   and
        interest, if any,  on deferred  amounts), waive  compliance by  a
        participant with any  obligation to  be performed by  him or  her
        under an Award, waive any term  or condition of an Award,  cancel
        an existing  Award in  whole or  in part  with the  consent of  a
        Participant, grant replacement Awards, accelerate the vesting  or
        lapse of any  restrictions of  any Award  and adopt  the form  of
        instruments evidencing  Awards under  the  Plan and  change  such
        forms from time to time.  Any interpretation by the Board of  the
        terms and provisions of the Plan or any Award thereunder and  the
        administration thereof, and all action taken by the Board,  shall
        be final, binding and  conclusive on all  parties and any  person
        claiming under or through any party.  No Director shall be liable
        for any action or  determination made in good  faith.  The  Board
        may, to the full extent permitted by law, delegate any or all  of
        its  responsibilities  under  the   Plan  to  a  committee   (the
        "Committee") appointed by the Board and consisting of one or more
        members  of  the  Board,   each  of  whom   shall  be  deemed   a
        "non-employee director" within the meaning of Rule 16b-3 (or  any
        successor rule)  of  the Securities  Exchange  Act of  1934  (the
        "Exchange Act").
PAGE
<PAGE>
        3.   Effective Date
             --------------

             The Plan shall be effective as of the date first approved by
        the Board of Directors,  subject to the approval  of the Plan  by
        the Corporation's Stockholders. Grants  of Awards under the  Plan
        made prior to such approval shall be effective when made  (unless
        otherwise specified by the Board at the time of grant), but shall
        be conditioned on and subject to such approval of the Plan.

        4.   Shares Subject to the Plan
             --------------------------

             Subject to adjustment as provided in Section 10.6, the total
        number of shares of the common  stock, $.01 par value per  share,
        of the Company (the "Common  Stock"), reserved and available  for
        distribution under the Plan shall be 700,000 shares.  Such shares
        may consist,  in whole  or in  part, of  authorized and  unissued
        shares or treasury shares.

             If any Award of shares of Common Stock requiring exercise by
        the Participant for  delivery of such  shares terminates  without
        having been  exercised  in full,  is  forfeited or  is  otherwise
        terminated without a payment being made to the Participant in the
        form of Common Stock, or if any shares of Common Stock subject to
        restrictions are repurchased by the Company pursuant to the terms
        of any  Award  or are  otherwise  reacquired by  the  Company  to
        satisfy obligations arising by virtue  of any Award, such  shares
        shall be  available for  distribution in  connection with  future
        Awards under the Plan.

        5.   Eligibility
             -----------

             Employees, officers and  Directors of,  and consultants  to,
        the Company  and  its  subsidiaries, or  other  persons  who  are
        expected to make significant  contributions to the future  growth
        and success of the Company and its subsidiaries shall be eligible
        to  receive  Awards  under  the  Plan.    The  Board,  or   other
        appropriate committee or person to the extent permitted  pursuant
        to the last sentence of Section 2, shall from time to time select
        from among such  eligible persons those  who will receive  Awards
        under the Plan.

        6.   Types of Awards
             ---------------

             The Board may  offer Awards under  the Plan in  any form  of
        equity-based     interest,     equity-based     incentive      or
        performance-based stock incentive in Common Stock of the  Company
        or any combination thereof.   The type, terms and conditions  and
        restrictions of an Award shall be determined by the Board at  the
        time such Award is made  to a Participant; provided however  that
        the maximum number of  shares permitted to  be granted under  any
        Award or combination of Awards to any participant during any  one
        calendar year may  not exceed 1%  of the shares  of Common  Stock
        outstanding at the beginning of such calendar year.
PAGE
<PAGE>
             An Award shall be  made at the time  specified by the  Board
        and shall be subject to such conditions or restrictions as may be
        imposed by  the Board  and  shall conform  to the  general  rules
        applicable under  the Plan  as  well as  any special  rules  then
        applicable under federal tax laws  or regulations or the  federal
        securities laws relating to the type of Award granted.

             Without  limiting  the  foregoing,   Awards  may  take   the
        following forms and shall be  subject to the following rules  and
        conditions:

             6.1  Options
                  -------

             An option is an Award  that entitles the holder on  exercise
        thereof to purchase Common Stock  at a specified exercise  price.
        Options granted  under the  Plan may  be either  incentive  stock
        options ("incentive stock options") that meet the requirements of
        Section 422A of  the Internal  Revenue Code of  1986, as  amended
        (the "Code"),  or  options that  are  not intended  to  meet  the
        requirements of Section 422A ("non-statutory options").

             6.1.1     Option Price.  The price at which Common Stock may
                       ------------
        be purchased upon exercise  of an option  shall be determined  by
        the Board, provided however, the exercise price shall not be less
                   ----------------
        than 85% of the then fair market value per share of Common Stock.

             6.1.2     Option Grants   .  The  granting of an  option shall
                       -------------
        take place at the time specified by the Board.  Options shall  be
        evidenced by option agreements.  Such agreements shall conform to
        the  requirements  of  the  Plan,  and  may  contain  such  other
        provisions (including but not  limited to vesting and  forfeiture
        provisions, acceleration, change  of control,  protection in  the
        event of merger,  consolidations, dissolutions and  liquidations)
        as the  Board  shall deem  advisable.   Option  agreements  shall
        expressly state whether an option grant is intended to qualify as
        an incentive stock option or non-statutory option.

             6.1.3     Option Period .  An option will become exercisable
                       -------------
        at such  time or  times  (which may  be  immediately or  in  such
        installments as the Board shall determine) and on such terms  and
        conditions as the  Board shall  specify.   The option  agreements
        shall specify the terms and conditions applicable in the event of
        an option holder's termination of employment during the  option's
        term.

             Any exercise of an option must be in writing, signed by  the
        proper person and delivered or mailed to the Company, accompanied
        by (1) any  additional documents  required by the  Board and  (2)
        payment in full in accordance  with Section 6.1.4 for the  number
        of shares for which the option is exercised.

             6.1.4     Payment of  Exercise Price.      Stock purchased  on
                       ---------------------------
        exercise of an option shall be paid for as follows:  (1) in  cash
        or by  check  (subject to  such  guidelines as  the  Company  may
PAGE
<PAGE>
        establish for this purpose), bank draft or money order payable to
        the order of the Company or (2) if so permitted by the instrument
        evidencing the option (or in the case of a non-statutory  option,
        by the Board at  or after grant of  the option), (i) through  the
        delivery of shares of Common Stock that have been outstanding for
        at least  six  months  (unless the  Board  expressly  approves  a
        shorter period) and that have a fair market value (determined  in
        accordance with procedures prescribed by the Board) equal to  the
        exercise price,  (ii) by  delivery of  a promissory  note of  the
        option holder  to  the Company,  payable  on such  terms  as  are
        specified by the Board, (iii) by delivery of an unconditional and
        irrevocable undertaking by  a broker to  deliver promptly to  the
        Company sufficient funds to  pay the exercise  price, or (iv)  by
        any combination of the permissible forms of payment.

             6.1.5     Buyout Provision.  The Board may at any time offer
                       ----------------

        incentive stock option shall be construed so that each  incentive
        stock option shall  be an  incentive stock option  as defined  in
        Section 422A  of the  Code or  any statutory  provision that  may
        replace such Section, and any  provisions thereof that cannot  be
        so  construed  shall  be  disregarded.    Instruments  evidencing
        incentive stock  options  must  contain such  provisions  as  are
        required under  applicable provisions  of  the Code.    Incentive

        option shall  not be  less than  100%  (110% in  the case  of  an
        incentive stock  option  granted  to  a  more  than  ten  percent
        Stockholder of  the Company)  of  the fair  market value  of  the
        Common Stock on the  date of grant, as  determined by the  Board.
        An incentive  stock option  may not  be granted  after the  tenth
        anniversary of the  date on  which the  Plan was  adopted by  the
        Board and the latest date on which an incentive stock option  may
        be exercised shall be  the tenth anniversary (fifth  anniversary,
        in the case of any incentive stock option granted to a more  than
        ten percent Stockholder of the Company) of the date of grant,  as
        determined by the Board.

        Common Stock  pursuant to  an Award  has been  satisfied by  past
        services rendered by the Participant.  The Board may agree at any
        time, upon request of the Participant, to defer the date on which
        any payment under an Award will be made.

        8.   Loans and Supplemental Grants
             -----------------------------

             The Company may make a loan  to a Participant, either on  or
        after the grant to  the Participant of  any Award, in  connection
        with the purchase  of Common Stock  under the Award  or with  the
        payment of any obligation incurred  or recognized as a result  of
        the Award.  The Board will have full authority to decide  whether
        the loan  is  to be  secured  or  unsecured or  with  or  without
        recourse against the borrower, the terms on which the loan is  to
        be repaid  and the  conditions, if  any, under  which it  may  be
        forgiven.

             In connection with any Award, the Board may at the time such
        Award is made or  at a later  date, provide for  and make a  cash
        payment to the participant not to  exceed an amount equal to  (a)
        the amount of any federal, state and local income tax or ordinary
        income for which the Participant  will be liable with respect  to
        the Award, plus (b)  an additional amount  on a grossed-up  basis
        necessary to make him or her whole after tax, discharging all the

             shall become fully  vested and all  such restrictions  shall

             free of restrictions.

             (c) Deferral limitations and  conditions that relate  solely
             to the passage of time, continued employment or affiliation,
             will be waived and removed  as to deferred stock Awards  and
             performance Awards.  Performance of other conditions  (other
             than conditions  relating solely  to  the passage  of  time,
             continued employment or affiliation) will continue to  apply
             unless otherwise provided  in the  agreement evidencing  the
             Awards or in any other agreement between the Participant and
             the Company or unless otherwise agreed by the Board.

        Directors of the Company,  Thermo Instrument or Thermo  Electron,
        as the case may  be, at any time  within two years following  any

             13d-5 under the Exchange Act);

             (b) "Prior Directors" shall mean the persons sitting on  the

        10.  General Provisions
             ------------------

             10.1 Documentation of Awards
                  -----------------------

             Awards will be evidenced  by written instruments, which  may
        differ among Participants, prescribed by  the Board from time  to
        time.  Such instruments  may be in the  form of agreements to  be
        executed by both the Participant and the Company or certificates,
        letters or similar instruments which need not be executed by  the
        participant but acceptance  of which will  evidence agreement  to
        the terms  thereof.    Such  instruments  shall  conform  to  the
        requirements of the  Plan and may  contain such other  provisions
        (including   provisions   relating    to   events   of    merger,
        consolidation, dissolution  and liquidations,  change of  control
        and restrictions  affecting either  the agreement  or the  Common
        Stock issued thereunder), as the Board deems advisable.

             10.2 Rights as a Stockholder
                  -----------------------

             Except  as  specifically  provided   by  the  Plan  or   the
        instrument evidencing the Award, the receipt of an Award will not
        give a Participant rights  as a Stockholder  with respect to  any
        shares covered by  an Award until  the date of  issue of a  stock
        certificate to the participant for such shares.

             10.3 Conditions on Delivery of Stock
                  -------------------------------

             The Company will not be  obligated to deliver any shares  of
        Common Stock pursuant to  the Plan or  to remove any  restriction
        from shares previously  delivered under  the Plan  (a) until  all
        conditions of  the  Award have  been  satisfied or  removed,  (b)
        until, in the  opinion of the  Company's counsel, all  applicable
        federal and state laws and  regulations have been complied  with,
        (c) if the outstanding Common Stock is at the time listed on  any
        stock exchange, until the shares  have been listed or  authorized
        to be listed on such  exchange upon official notice of  issuance,
        and (d)  until all  other legal  matters in  connection with  the
        issuance and delivery of  such shares have  been approved by  the
        Company's counsel.   If the  sale of  Common Stock  has not  been
        registered under  the Securities  Act of  1933, as  amended,  the
        Company may require,  as a  condition to exercise  of the  Award,
        such representations or agreements as counsel for the Company may
        consider appropriate  to  avoid violation  of  such act  and  may
        require that the certificates  evidencing such Common Stock  bear
        an appropriate legend restricting transfer.

             If  an  Award  is  exercised  by  the  participant's   legal
        representative, the  Company  will  be  under  no  obligation  to
        deliver Common Stock pursuant to such exercise until the  Company
        is satisfied as to the authority of such representative.

             10.4 Tax Withholding
                  ---------------
PAGE
<PAGE>
             The  Company  will  withhold  from  any  cash  payment  made
        pursuant to an Award an amount sufficient to satisfy all federal,
        state and local  withholding tax  requirements (the  "withholding
        requirements").

             In the case of an Award  pursuant to which Common Stock  may
        be delivered, the Board will have  the right to require that  the
        participant or other appropriate person  remit to the Company  an
        amount sufficient  to satisfy  the withholding  requirements,  or
        make other arrangements satisfactory to the Board with regard  to
        such requirements, prior to the delivery of any Common Stock.  If
        and to the extent  that such withholding  is required, the  Board
        may permit the participant or such other person to elect at  such
        time and in such manner as the Board provides to have the Company
        hold back from the shares to  be delivered, or to deliver to  the
        Company, Common Stock  having a value  calculated to satisfy  the
        withholding requirement.

             10.5 Nontransferability of Awards
                  ----------------------------

             Except as  may  be authorized  by  the Board,  in  its  sole
        discretion, no  Award  (other than  an Award in  the form  of an
        outright transfer  of cash  or Common  Stock not  subject to  any
        restrictions) may be transferred other  than by will or the  laws
        of descent and distribution,  and during a Participant's lifetime
        an Award requiring exercise may be  exercised only by him or  her
        (or in the event  of incapacity, the  person or persons  properly
        appointed to act  on his or  her behalf).  The Board  may, in its
        discretion, determine the  extent to  which Awards  granted to  a
        Participant shall be transferable, and such provisions permitting
        or acknowledging  transfer  shall be  set  forth in  the  written
        agreement  evidencing the Award executed and  delivered by or  on
        behalf of the Company and the Participant.

             10.6 Adjustments in the Event of Certain Transactions
                  ------------------------------------------------

             (a)   In the  event  of a  stock  dividend, stock  split  or
        combination of  shares,   the  Board  will make  (i)  appropriate
        adjustments to the maximum number of shares that may be delivered
        under the  Plan  under  Section 4  above,  and  (ii)  appropriate
        adjustments to  the  number  and  kind  of  shares  of  stock  or
        securities subject  to Awards  then outstanding  or  subsequently
        granted, any exercise  prices relating  to Awards  and any  other
        provisions of Awards affected by such change.

             (b)  The Board may also make appropriate adjustments to take
        into account material changes in  law or in accounting  practices
        or    principles,    mergers,    consolidations,    acquisitions,
        dispositions,  repurchases  or  similar  corporate  transactions,
        recapitalizations   or    other   change    in   the    Company's
        capitalization, or  other  distribution with  respect  to  common
        Stockholders other than normal cash dividends,or any other event,
        if it is determined by the Board that adjustments are appropriate
        to avoid distortion  in the operation  of the Plan,  but no  such
PAGE
<PAGE>
        adjustments other than those required by law may adversely affect
        the rights of any Participant (without the Participant's consent)
        under any Award previously granted.

             10.7 Employment Rights
                  -----------------

             Neither the adoption  of the  Plan nor the  grant of  Awards
        will confer upon  any person  any right  to continued  employment
        with the Company or any subsidiary  or interfere in any way  with
        the  right  of  the  Company  or  subsidiary  to  terminate   any
        employment relationship at  any time or  to increase or  decrease
        the compensation of such person.  Except as specifically provided
        by the Board  in any  particular case,  the loss  of existing  or
        potential profit  in  Awards  granted under  the  Plan  will  not
        constitute an element of damages  in the event of termination  of
        an  employment  relationship  even  if  the  termination  is   in
        violation of an obligation of the Company to the employee.

             Whether an  authorized  leave  of  absence,  or  absence  in
        military or government service,  shall constitute termination  of
        employment shall be  determined by the  Board at the  time.   For
        purposes of this Plan, transfer of employment between the Company

             The Plan  shall  remain  in  full  force  and  effect  until
        terminated by the Board.   Subject to the  last sentence of  this
        Section 11, the Board may at any time or times amend the Plan  or
        any outstanding Award  for any purpose  that may at  the time  be
        permitted by law, or may at any time terminate the Plan as to any
        further grants of Awards.   No amendment, unless approved by  the
        Stockholders, shall be effective  if it would  cause the Plan  to
        fail to  satisfy  the requirements  of  the federal  tax  law  or
        regulation  relating   to   incentive  stock   options   or   the
        requirements of  Rule  16b-3  (or  any  successor  rule)  of  the

        evidencing Awards under the Plan may adversely affect the  rights
        of any  participant under  any Award  previously granted  without
        such participant's consent.

             Corporation    (the  "Company")  may  elect  to  have  such
             percentage as he or  she may specify  of the fees  otherwise
             payable to him  or her deferred  and paid to  him or her  as
             provided in this Plan.  A director who is also an officer of
             the Company  or  its  parent  corporation,  Thermo  Electron
             Corporation, shall not  be eligible to  participate in  this
             Plan.   Each election  shall be  made by  notice in  writing
             delivered to the Clerk  of the Company , in such form as the
             Clerk shall designate, and each election shall be applicable

             participant's  consent,   may   designate   (the   "deferral
             termination date").   In  the event  that the  participant's
             deferral termination date  is the  date on which  he or  she
             ceases to  engage  in his  or  her principal  occupation  or
             employment, the  participant  or a  personal  representative
             shall advise  the Company  of that  date by  written  notice
             delivered to the Clerk of the Company.

             --------
             deferred  compensation  account,  as  of  the  end  of  each
             quarter, an amount equal to his or her fees for that quarter
             which that participant shall  have elected to have  deferred
             pursuant to Section 1.

             Section 4.     Stock Units  and Stock  Unit Accounts.   All
             ----------     --------------------------------------
             amounts allocated to  a participant's deferred  compensation
             account pursuant  to  Section 3  and  Section  5  shall  be
             converted, at the  end of each quarter, into  stock units by
             dividing   the   accumulated   balance   in   the   deferred
             compensation account as of  the end of  that quarter by  the

             rounded to the  nearest one-hundredth of  a share, shall  be
             credited to a separate stock unit account to be  established
             for the participant, and the  aggregate value thereof as  of
             the last business day  of that quarter  shall be charged  to
             the participant's deferred compensation account. No  amounts
             credited to the participant's deferred compensation  account
             pursuant to Section 5 subsequent to the close of the  fiscal
             year in which occurs the participant's deferral  termination
             date shall be converted into  stock units.  Any such  amount

             account, until all distributions  shall have been made  from
             the participant's stock  unit account, in  amounts equal  to
             the cash dividends  (or the fair  market value of  dividends
             paid in  property other  than  dividends payable  in  common
             stock of  the  Company)  which the  participant  would  have
             received from time to time had  he or she been the owner  on
             the record dates for  the payment of  such dividends of  the
             number of shares of the Company's common stock equal to  the

             all  distributions   shall   have   been   made   from   the
             participant's stock unit account, of a number of units equal
             to the  number  of shares  of  the Company's  common  stock,
             rounded  to  the  nearest  one-hundredth  share,  which  the
             participant would have received from  time to time as  stock
             dividends had he or she been  the owner on the record  dates
             for the payments of  such stock dividends  of the number  of
             units of the Company's common  stock equal to the number  of
             units credited to  his or  her stock unit  account on  those

             -------------  ------------------------------
             participant's deferral  termination  date shall  occur,  the
             Company shall  become obligated  to make  the  distributions
             prescribed in the following paragraphs (a) and (b).

                  (a)  The  Company shall distribute  to the  participant
             the number  of shares  of the  common stock  of the  Company
             which shall equal the total  number of units accumulated  in
             his or her stock unit account as of the close of the  fiscal
             year in which  the participant's  deferral termination  date
             occurs. Such  distribution of  stock shall  be made  in  ten
             annual installments, unless,  at least six  months prior  to
             his or her deferral termination date, the participant  shall
             have elected, by notice in writing filed with the  Secretary
             of the  Company,  to have  such  distribution made  in  five
             annual installments. In either  such case, the  installments
             shall be of as nearly equal number of shares as practicable,
             adjusted to reflect any changes pursuant to Sections 6 and 7
             in the number of units remaining in the participant's  stock
             unit  account.    The   first  such  installment  shall   be
             distributed within 60  days after  the close  of the  fiscal
             year in which  the participant's  deferral termination  date
             occurs.  The remaining installments shall be distributed  at
             annual  intervals  thereafter.    Anything  herein  to   the
             contrary notwithstanding, the Company shall have the option,
             if its Board of Directors shall by resolution so  determine,
             in lieu  of  making  distribution  in  ten  or  five  annual
             installments as  set  forth above,  with  the  participant's
             consent, to distribute stock  or any remaining  installments
             thereof in a single distribution  at any time following  the
             close of the fiscal year in which the participant's deferral
             termination  date  occurs.    Distribution  of  stock   made
             hereunder may be made  from shares of  common stock held  in
             the treasury and/or from shares of authorized but previously
             unissued shares of  common stock.   All distributions  under
             the plan  shall be  completed not  later than  December  31,
             2025.

                  (b)  The  Company shall distribute  to the  participant
             sums in cash  equal to the  balance credited to  his or  her
             deferred compensation account as of the close of the  fiscal
             year in which  his or her  deferral termination date  occurs
             plus such additional  amounts as shall  be credited  thereto
             from time to  time thereafter  pursuant to Section  5.   The
             cash distribution shall  be made  on the same  dates as  the
             annual distributions made pursuant  to paragraph (a)  above,
             and each  cash  distribution  shall consist  of  the  entire
             balance credited to the participant's deferred  compensation
             account at the time of the annual distribution.

                  If a  participant's  deferral  termination  date  shall
             occur by reason of his  or her death or  if he or she  shall
PAGE
<PAGE>
             die after his or her deferral termination date but prior  to
             receipt of al l distributions of stock and cash provided for
             in  this   Section  8,   all   stock  and   cash   remaining
             distributable  hereunder  shall   be  distributed  to   such
             beneficiary as  the  participant shall  have  designated  in
             writing and   filed with the Secretary  of the Company or, in
             the absence of  designation, to  the participant's  personal
             representative.   Such distributions  shall be  made in  the
             same manner and  at the  same intervals as  they would  have
             been made  to the  participant had  he or  she continued  to
             live.

             Section 9.     Participant's Rights Unsecured   The right of
             ---------      ------------------------------
             any participant  to receive  distributions under  Section  8
             shall be an  unsecured claim against  the general assets  of
             the Company. The Company may  but shall not be obligated  to
             acquire shares of its outstanding common stock from time  to
             time  in  anticipation  of  its  obligation  to  make   such
             distributions, but no participant  shall have any rights  in
             or against any shares of  stock so acquired by the  Company.
             All such  stock  shall  constitute  general  assets  of  the
             Company and may be disposed of  by the Company at such  time
             and for such purposes as it may deem appropriate.

             accounts upon any change of control of the Company.   Either
             of the following shall be deemed to be a change of  control:
             (a) the occurrence, without the prior approval of the  Board
             of Directors, of the acquisition, directly or indirectly, by

             beneficial owner of  25% or more  of the outstanding  common
             stock of  Thermo Electron  Corporation ("Thermo  Electron"),
             without the prior  approval of  the prior  directors of  the
             Company, Thermo Instrument , or Thermo Electron, as the case
             may be; (b) the failure of the prior directors to constitute
             a majority of the Board of Directors of the Company,  Thermo
             Instrument  or Thermo Electron, at any time within two years
             following any electoral event.  As used in this sentence and
             the preceding sentence, person shall mean a natural  person,
             an entity (together with an affiliate thereof, as defined in

             defined in Rule 13d-5 under  the Securities Exchange Act  of
             1934; prior directors shall mean the persons serving on  the
             Board of Directors immediately prior to any electoral event;
             and electoral  event shall  mean any  contested election  of
             directors or any tender or  exchange offer for common  stock
             of the Company, Thermo Instrument  or Thermo Electron  by any
             person other  than the  Company, Thermo  Instrument, Thermo
             Electron  or a subsidiary of any of the foregoing companies.

             The Board of Directors at  any time, at its discretion,  may
             terminate the Plan.   If the  Board of Directors  terminates
             the Plan after  any person  or group of  persons shall  have
             acquired or  proposed  to  acquire control  of  the  Company

             all participants' deferred  compensation accounts and  stock
             unit accounts.    Otherwise,  distributions  in  respect  of
             credits to participants' deferred compensation accounts  and

        of  their  service   to,  and  activities   on  behalf  of,   the
        corporation;

             WHEREAS,   uncertainties   relating    to   the    continued
        availability  of  adequate   directors  and  officers   liability
        insurance ("D&O  Insurance") and  the uncertainties  relating  to
        indemnification have increased the  difficulty of attracting  and
        retaining such persons;

             WHEREAS, the Board of Directors of the Company (the "Board")
        has determined that  the difficulty in  attracting and  retaining
        such  persons  is  detrimental  to  the  best  interests  of  the
        Company's stockholders and that the Company should act to  assure
        such persons  that  there will  be  increased certainty  of  such
        protection in the future;

             WHEREAS, it  is reasonable,  prudent and  necessary for  the
        Company  contractually  to  obligate  itself  to  indemnify  such
        persons to the fullest extent permitted by applicable law so that
        they will serve or continue to serve the Company free from  undue
        concern that they will not be so indemnified;

             WHEREAS, Indemnitee is willing  to serve, continue to  serve
        and/or to take  on additional  service for  or on  behalf of  the
        Company on the condition that he be so indemnified and that  such
        indemnification be so guaranteed.

             NOW, THEREFORE,  in consideration  of the  premises and  the
        covenants contained herein, the Company and Indemnitee do  hereby
        covenant and agree as follows:

             1.   Services by Indemnitee.   Indemnitee agrees to serve or
        continue to serve as a Director  of the Company.  This  agreement
        shall not impose any obligation on the Indemnitee or the  Company
        to continue the Indemnitee's position with the Company beyond any
        period otherwise applicable.

                                 2
             2.   Indemnity.   The  Company shall  indemnify,  and  shall
        advance Expenses  (as  hereinafter  defined)  to,  Indemnitee  as
        provided in this Agreement and to the fullest extent permitted by
        law.

             3.   General.  Indemnitee shall be entitled to the rights of
        indemnification provided in this Section  3 if, by reason of  his
        Corporate  Status  (as  hereinafter   defined),  he  is,  or   is
        threatened to be  made, a  party to any  threatened, pending,  or
        completed  action,   suit,   arbitration,   alternative   dispute
        resolution mechanism,  investigation, administrative  hearing  or
        other  proceeding  whether  civil,  criminal,  administrative  or
        investigative.  Pursuant to this  Section 3, Indemnitee shall  be
        indemnified against  Expenses,  judgments, penalties,  fines  and
        amounts paid in settlement  incurred by him or  on his behalf  in
        connection  with  such  action,  suit,  arbitration,  alternative
        dispute  resolution   mechanism,  investigation,   administrative
        hearing   or   other   proceeding   whether   civil,    criminal,
        administrative or  investigative or  any claim,  issue or  matter
        therein, if he acted in good faith and in a manner he  reasonably
        believed to be  in or not  opposed to the  best interests of  the
        Company, and, with respect to any criminal action or  proceeding,
        had no reasonable cause to believe his conduct was unlawful.

             4.   Proceedings by or in the Right of the Company.   In the
        case of any action  or suit by  or in the  right of the  Company,
        indemnification shall be made  only (i) for  Expenses or (ii)  in
        respect of  any claim,  issue or  matter as  to which  Indemnitee
        shall have been  adjudged to  be liable  to the  Company if  such
        indemnification is permitted by Delaware law; provided,  however,
        that indemnification against Expenses shall nevertheless be  made
        by the Company  in such  event to the  extent that  the Court  of
        Chancery of the  State of Delaware,  or the court  in which  such
        action or  suit shall  have  been brought  or is  pending,  shall
        determine to be proper despite the adjudication of liability  but
        in view of all the circumstances of the case.

             5.   Indemnification for Expenses of  a Party who is  Wholly
        or Partly  Successful.   Notwithstanding any  other provision  of
        this Agreement, to the  extent that Indemnitee  is, by reason  of
        his Corporate Status, a party to and is successful, on the merits
        or otherwise,  in  any  action,  suit,  arbitration,  alternative
        dispute  resolution   mechanism,  investigation,   administrative
        hearing   or   other   proceeding   whether   civil,    criminal,
        administrative or investigative, he shall be indemnified  against
        all Expenses  incurred by  him  or on  his behalf  in  connection
        therewith.   If  Indemnitee  is  not  wholly  successful  but  is
        successful, on the  merits or otherwise,  as to one  or more  but
        less than all  claims, issues  or matters in  such action,  suit,
        arbitration,   alternative    dispute    resolution    mechanism,
        investigation, administrative hearing or other proceeding whether
        civil, criminal,  administrative  or investigative,  the  Company
        shall indemnify Indemnitee against  all Expenses incurred by  him
        or on his  behalf in connection  with each successfully  resolved
PAGE
<PAGE>
                                        3
        claim, issue or matter.  For purposes of this Section and without
        limitation, the  termination of  any claim,  issue or  matter  by
        dismissal, or  withdrawal, with  or without  prejudice, shall  be
        deemed to  be a  successful result  as to  such claim,  issue  or
        matter.

             6.   Advance of  Expenses.   The Company  shall advance  all
        Expenses incurred by  or on  behalf of  Indemnitee in  connection
        with  any   action,   suit,  arbitration,   alternative   dispute
        resolution mechanism,  investigation, administrative  hearing  or
        any other proceeding whether  civil, criminal, administrative  or
        investigative within twenty  (20) days after  the receipt by  the
        Company of a statement  or statements from Indemnitee  requesting
        such advance or advances from time  to time, whether prior to  or
        after  final  disposition  of  such  action,  suit,  arbitration,
        alternative   dispute   resolution   mechanism,    investigation,
        administrative hearing  or any  other proceeding  whether  civil,
        criminal, administrative  or  investigative.  Such  statement  or
        statements shall  reasonably evidence  the Expenses  incurred  by
        Indemnitee and shall include or be preceded or accompanied by  an
        undertaking by or on behalf  of Indemnitee to repay any  Expenses
        advanced if it shall ultimately be determined that Indemnitee  is
        not entitled  to  be  indemnified against  such  Expenses,  which
        undertaking shall  be accepted  by or  on behalf  of the  Company
        without reference to the financial ability of Indemnitee to  make
        repayment.

             7.   Procedure   for   Determination   of   Entitlement   to
        Indemnification.

             (a)  To  obtain   indemnification  under   this   Agreement,
        Indemnitee  shall  submit  to  the  Company  a  written  request,
        including therein or therewith such documentation and information
        as is  reasonably  available  to  Indemnitee  and  is  reasonably
        necessary to determine whether and  to what extent Indemnitee  is
        entitled to indemnification.  The Secretary of the Company shall,
        promptly upon  receipt of  such  a request  for  indemnification,
        advise  the  Board  in  writing  that  Indemnitee  has  requested
        indemnification.

             (b)  Upon written request by Indemnitee for  indemnification
        pursuant to Section 7(a) hereof, a determination, if required  by
        applicable law, with respect to Indemnitee's entitlement  thereto
        shall be made in  the specific case: (i)  if a Change in  Control
        (as hereinafter  defined)  shall have  occurred,  by  Independent
        Counsel (as  hereinafter defined)  in a  written opinion  to  the
        Board, a copy of which  shall be delivered to Indemnitee  (unless
        Indemnitee shall request that such  determination be made by  the
        Board or the Stockholders, in which case the determination  shall
        be made in the manner provided  below in clauses (ii) or  (iii));
        (ii) if a Change of Control  shall not have occurred, (A) by  the
        Board by a majority vote of a quorum consisting of  Disinterested
        Directors (as hereinafter  defined), or  (B) if a  quorum of  the
        Board consisting of Disinterested Directors is not obtainable or,
PAGE
<PAGE>
                                        4
        even if  obtainable, such  quorum of  Disinterested Directors  so
        directs, by  Independent  Counsel in  a  written opinion  to  the
        Board, a copy of which shall be delivered to Indemnitee or (C) by
        the Stockholders of the Company; or (iii) as provided in  Section
        8(b) of  this  Agreement;  and,  if  it  is  so  determined  that
        Indemnitee is entitled to indemnification, payment to  Indemnitee
        shall be  made within  ten (10)  days after  such  determination.
        Indemnitee shall  cooperate with  the person,  persons or  entity
        making  such   determination   with   respect   to   Indemnitee's
        entitlement  to  indemnification,  including  providing  to  such
        person, persons  or entity  upon reasonable  advance request  any
        documentation or information that is not privileged or  otherwise
        protected from  disclosure and  that is  reasonably available  to
        Indemnitee and reasonably necessary  to such determination.   Any
        costs or expenses (including  attorneys' fees and  disbursements)
        incurred by Indemnitee in  so cooperating shall  be borne by  the
        Company (irrespective  of the  determination as  to  Indemnitee's
        entitlement  to   indemnification)   and   the   Company   hereby
        indemnifies and agrees to hold Indemnitee harmless therefrom.

             (c)  In  the  event  the  determination  of  entitlement  to
        indemnification is to be made by Independent Counsel pursuant  to
        Section 7(b) of this Agreement, the Independent Counsel shall  be
        selected as  provided in  this  Section 7(c).    If a  Change  of
        Control shall not have occurred, the Independent Counsel shall be
        selected by the Board, and the Company shall give written  notice
        to Indemnitee advising  him of  the identity  of the  Independent
        Counsel so selected.  If a Change of Control shall have occurred,
        the Independent Counsel shall  be selected by Indemnitee  (unless
        Indemnitee shall  request  that such  selection  be made  by  the
        Board, in which  event the preceding  sentence shall apply),  and
        Indemnitee shall give written notice  to the Company advising  it
        of the  identity of  the  Independent Counsel  so selected.    In
        either event, Indemnitee or the Company, as the case may be, may,
        within 7 days after such  written notice of selection shall  have
        been given, deliver to the Company or to Indemnitee, as the  case
        may be, a written  objection to such  selection.  Such  objection
        may be asserted only on  the ground that the Independent  Counsel
        so selected  does  not  meet  the  requirements  of  "Independent
        Counsel" as  defined in  Section 14  of this  Agreement, and  the
        objection shall set forth with particularity the factual basis of
        such  assertion.    If  such  written  objection  is  made,   the
        Independent Counsel  so selected  may  not serve  as  Independent
        Counsel unless  and  until  a  court  has  determined  that  such
        objection is without  merit. If,  within twenty  (20) days  after
        submission by Indemnitee of a written request for indemnification
        pursuant to  Section 7(a)  hereof, no  Independent Counsel  shall
        have been selected or if  selected, shall have been objected  to,
        in accordance  with  this Section  7(c),  either the  Company  or
        Indemnitee may petition  the Court  of Chancery of  the State  of
        Delaware or other court of competent jurisdiction for  resolution
        of any objection  which shall have  been made by  the Company  or
        Indemnitee to the other's selection of independent counsel and/or
        for the appointment as independent  counsel of a person  selected
PAGE
<PAGE>
                                        5
        by the  Court  or  by  such  other  person  as  the  Court  shall
        designate, and the person  with respect to  whom an objection  is
        favorably resolved  or  the  person so  appointed  shall  act  as
        Independent Counsel under Section 7(b) hereof.  The Company shall
        pay reasonable fees and expenses of Independent Counsel  incurred
        by such Independent Counsel in connection with acting pursuant to
        Section  7(b)  hereof.    The  Company  shall  pay  any  and  all
        reasonable fees and expenses incident  to the procedures of  this
        Section 7(c), regardless of the manner in which such  Independent
        Counsel was selected or appointed.  Upon the due commencement  of
        any  judicial  proceeding  or  arbitration  pursuant  to  Section
        9(a)(iii)  of  this  Agreement,  Independent  Counsel  shall   be
        discharged and  relieved of  any further  responsibility in  such
        capacity (subject  to the  applicable standards  of  professional
        conduct then prevailing).

             8.   Presumptions and Effect of Certain Proceedings.

             (a)  If a Change of Control shall have occurred, in making a
        determination with  respect  to  entitlement  to  indemnification
        hereunder,  the   person,   persons   or   entity   making   such
        determination  shall  presume  that  Indemnitee  is  entitled  to
        indemnification under this Agreement if Indemnitee has  submitted
        a request for indemnification in accordance with Section 7(a)  of
        this Agreement, and the Company shall have the burden of proof to
        overcome that presumption  in connection with  the making by  any
        person, persons or entity of  any determination contrary to  that
        presumption.

             (b)  If the person, persons or entity empowered or  selected
        under Section 7 of this Agreement to determine whether Indemnitee
        is  entitled  to  indemnification   shall  not  have  made   such
        determination within sixty (60) days after receipt by the Company
          of  the  request  therefor,  the  requisite  determination   of
        entitlement to indemnification shall be deemed to have been  made
        and Indemnitee shall be entitled to such indemnification,  absent
        (i) a  misstatement  by Indemnitee  of  a material  fact,  or  an
        omission of  a  material  fact  necessary  to  make  Indemnitee's
        statement not  materially  misleading,  in  connection  with  the
        request for  indemnification,  or  (ii)  a  prohibition  of  such
        indemnification under  applicable  law; provided,  however,  that
        such 60-day period may be extended for a reasonable time, not  to
        exceed an additional thirty (30) days, if the person, persons  or
        entity making the  determination with respect  to entitlement  to
        indemnification in good faith  requires such additional time  for
        the obtaining or evaluating  of documentation and/or  information
        relating thereto;  and  provided,  further,  that  the  foregoing
        provisions of  this  Section 8(b)  shall  not apply  (i)  if  the
        determination of entitlement to indemnification is to be made  by
        the stockholders pursuant to Section  7(b) of this Agreement  and
        if (A) within fifteen (15) days  after receipt by the Company  of
        the request  for such  determination the  Board has  resolved  to
        submit  such  determination   to  the   stockholders  for   their
        consideration at  an annual  meeting thereof  to be  held  within
PAGE
<PAGE>
                                        6
        seventy-five (75) days after such receipt and such  determination
        is made  thereat, or  (B) a  special meeting  of stockholders  is
        called within  fifteen  (15)  days after  such  receipt  for  the
        purpose of making  such determination, such  meeting is held  for
        such purpose within sixty (60)  days after having been so  called
        and  such  determination  is  made   thereat,  or  (ii)  if   the
        determination of entitlement to indemnification is to be made  by
        Independent Counsel pursuant to Section 7(b) of this Agreement.

             (c)  The  termination  of  any  action,  suit,  arbitration,
        alternative   dispute   resolution   mechanism,    investigation,
        administrative  hearing  or   other  proceeding  whether   civil,
        criminal, administrative or investigative or of any claim,  issue
        or matter therein by  judgment, order, settlement or  conviction,
        or upon a plea of nolo contendere  or its equivalent,  shall not
        (except as  otherwise expressly  provided in  this Agreement)  of
        itself   adversely   affect   the   right   of   Indemnitee    to
        indemnification or create a  presumption that Indemnitee did  not
        act in good faith and in a manner which he reasonably believed to
        be in or  not opposed to  the best interests  of the Company  or,
        with  respect  to  any   criminal  action  or  proceeding,   that
        Indemnitee had reasonable cause to  believe that his conduct  was
        unlawful.

             9.   Remedies of Indemnitee.

             (a)  In the event that (i) a determination is made  pursuant
        to Section 7 of this Agreement that Indemnitee is not entitled to
        indemnification  under  this   Agreement,  (ii)  advancement   of
        Expenses is  not  timely  made  pursuant to  Section  6  of  this
        Agreement,   (iii)   the   determination   of   entitlement    to
        indemnification is to be made by Independent Counsel pursuant  to
        Section 7(b) of this Agreement  and such determination shall  not
        have been made and delivered  in a written opinion within  ninety
        (90) days  after  receipt  by  the Company  of  the  request  for
        indemnification, (iv)  payment  of indemnification  is  not  made
        pursuant to  Section 5  of this  Agreement within  ten (10)  days
        after receipt by the  Company of a  written request therefor,  or
        (v) payment of indemnification is  not made within ten (10)  days
        after a determination has been  made that Indemnitee is  entitled
        to indemnification or such determination  is deemed to have  been
        made pursuant to Section 8 of this Agreement, Indemnitee shall be
        entitled to an adjudication in an appropriate court of the  State
        of Delaware, or in any other court of competent jurisdiction,  of
        his  entitlement  to  such  indemnification  or  advancement   of
        Expenses.  Alternatively, Indemnitee, at his option, may seek  an
        award in  arbitration  to be  conducted  by a  single  arbitrator
        pursuant to the  rules of the  American Arbitration  Association.
        Indemnitee shall commence such proceeding seeking an adjudication
        or an award in arbitration  within one hundred eighty (180)  days
        following the date  on which  Indemnitee first has  the right  to
        commence such  proceeding pursuant  to this  Section 9(a).    The
        Company shall  not oppose  Indemnitee's right  to seek  any  such
        adjudication or award in arbitration.

                                        7
             (b)  In the event that a determination shall have been  made
        pursuant to Section 7  of this Agreement  that Indemnitee is  not
        entitled  to   indemnification,   any  judicial   proceeding   or
        arbitration  commenced  pursuant  to  this  Section  9  shall  be
        conducted in all respects as a  de novo  trial, or arbitration, on
        the merits and Indemnitee  shall not be  prejudiced by reason  of
        that adverse determination.   If a Change  of Control shall  have
        occurred, in  any judicial  proceeding or  arbitration  commenced
        pursuant to this Section 9 the  Company shall have the burden  of
        proving that  Indemnitee is  not entitled  to indemnification  or
        advancement of Expenses, as the case may be.

             (c)  If a determination  shall have been  made or deemed  to
        have been made pursuant to Section 7 or 8 of this Agreement  that
        Indemnitee is entitled to  indemnification, the Company shall  be
        bound  by  such  determination  in  any  judicial  proceeding  or
        arbitration commenced pursuant  to this Section  9, absent (i)  a
        misstatement by Indemnitee of a material fact, or an omission  of
        a material  fact necessary  to  make Indemnitee's  statement  not
        materially  misleading,  in  connection  with  the  request   for
        indemnification, or (ii)  a prohibition  of such  indemnification
        under applicable law.

             (d)  The Company shall  be precluded from  asserting in  any
        judicial proceeding  or arbitration  commenced pursuant  to  this
        Section 9 that the procedures and presumptions of this  Agreement
        are not valid, binding and enforceable and shall stipulate in any
        such court  or before  any such  arbitrator that  the Company  is
        bound by all the provisions of this Agreement.

             (e)  In the event that Indemnitee, pursuant to this  Section
        9, seeks a judicial adjudication of or an award in arbitration to
        enforce his rights under,  or to recover  damages for breach  of,
        this Agreement, Indemnitee shall be entitled to recover from  the
        Company, and shall be indemnified by the Company against, any and
        all expenses  (of  the  types  described  in  the  definition  of
        Expenses in Section 14 of this Agreement) actually and reasonably
        incurred by him in such judicial adjudication or arbitration, but
        only if he prevails  therein. If it shall  be determined in  said
        judicial adjudication or arbitration that Indemnitee is  entitled
        to receive part but not all of the indemnification or advancement
        of expenses  sought,  the  expenses  incurred  by  Indemnitee  in
        connection with such judicial  adjudication or arbitration  shall
        be appropriately prorated.

             10.  Security.  To  the extent requested  by the  Indemnitee
        and approved by the Board, the  Company may at any time and  from
        time to time provide security to the Indemnitee for the Company's
        obligations hereunder through an irrevocable bank line of credit,
        funded trust  or  other  collateral.   Any  such  security,  once
        provided to  the  Indemnitee,  may not  be  revoked  or  released
        without the prior written consent of Indemnitee.

        proceeding commenced by Indemnitee pursuant to Section 9 of  this
        Agreement relating thereto.  This Agreement shall be binding upon
        the Company and its successors and assigns and shall inure to the
        benefit   of   Indemnitee   and   his   heirs,   executors    and
        administrators.

             (b)  To the extent that the Company maintains D&O Insurance,
        Indemnitee shall be covered by  such D&O Insurance in  accordance
        with its terms to  the maximum extent  of the coverage  available
        for any Director under such policy or policies.

             (c)  In the event of any  payment under this Agreement,  the
        Company shall be subrogated to the extent of such payment to  all

        papers required  and take  all action  necessary to  secure  such
        rights, including execution of such documents as are necessary to
        enable the Company to bring suit to enforce such rights.

             (d)  The Company shall not be liable under this Agreement to

        Section of this Agreement containing  any such provision held  to
        be invalid, illegal or unenforceable, that is not itself invalid,
        illegal or unenforceable)  shall not  in any way  be affected  or

        provision held to be invalid,  illegal or unenforceable, that  is
        not itself invalid, illegal or unenforceable) shall be  construed

        held invalid, illegal or unenforceable.

             13.  Exception to Right of Indemnification or Advancement of
        Expenses.  Notwithstanding any other provision of this Agreement,
        Indemnitee  shall   not  be   entitled  to   indemnification   or

        action, suit  or proceeding,  or  any claim  therein,  initiated,
        brought or made by him (i)  against the Company, unless a  Change
        in Control shall have occurred, or (ii) against any person  other
        than the Company, unless approved in advance by the Board.

             14.  Definitions.  For purposes of this Agreement:

             (a)  "Change in Control"  means a change  in control of  the
             Company of a nature that would be required to be reported in
             response to Item 5(f) of Schedule 14A of Regulation 14A  (or
             in response to any similar  item on any similar schedule  or
             form) promulgated under the Securities Exchange Act of  1934
             (the "Act"), whether or not  the Company is then subject  to
             such reporting requirement; provided, however, that, without
             limitation, such a Change in Control shall be deemed to have
             occurred if  (i)  any "person"  (as  such term  is  used  in
             Section 13(d)  and  14(d) of  the  Act) is  or  becomes  the
             "beneficial owner" (as defined in Rule 13d-3 under the Act),
             directly  or  indirectly,  of  securities  of  the   Company
             representing 20% or more of the combined voting power of the
             Company's then  outstanding  securities  without  the  prior
             approval of at least two-thirds of the members of the  Board
             in office immediately  prior to such  person attaining  such
             percentage interest;  (ii)  the  Company is  a  party  to  a
             merger,   consolidation,   sale    of   assets   or    other
             reorganization, or  a proxy  contest,  as a  consequence  of
             which members of  the Board in  office immediately prior  to
             such transaction or event constitute less than a majority of
             the Board  thereafter; or  (iii) during  any period  of  two
             consecutive years, individuals who at the beginning of  such
             period constituted the Board (including for this purpose any
             new director whose  election or nomination  for election  by
             the Company's  stockholders was  approved by  a vote  of  at
             least two-thirds of the directors  then still in office  who
             were directors at  the beginning of  such period) cease  for
             any reason to constitute at least a majority of the Board.

             (b)  "Corporate Status" describes the status of a person who
             is or was or has agreed to become a director of the Company,
             or is or was  an officer or fiduciary  of the Company or  of
             any other  corporation, partnership,  joint venture,  trust,
             employee benefit plan or other enterprise which such  person
             is or was serving at the request of the Company.

             (c)  "Disinterested  Director"  means  a  director  of   the
             Company who is not and was not a party to the action,  suit,
             arbitration,  alternative   dispute  resolution   mechanism,
             investigation,   administrative   hearing   or   any   other
             proceeding  whether  civil,   criminal,  administrative   or
             investigative in respect of which indemnification is  sought
             by Indemnitee.

             (d)  "Expenses"  shall  include  all  reasonable  attorneys'
             fees, retainers,  court  costs, transcript  costs,  fees  of
             experts, travel  expenses, duplicating  costs, printing  and
             binding costs, telephone charges, postage, delivery  service
             fees, and all other disbursements  or expenses of the  types

             an action, suit, arbitration, alternative dispute resolution
             mechanism,  investigation,  administrative  hearing  or  any
             other proceeding whether civil, criminal, administrative  or
             investigative.

             (e)  "Independent Counsel" means a law firm, or a member  of
             a law firm,  that is experienced  in matters of  corporation
             law and neither currently is, nor in the past five years has
             been, retained to represent:  (i) the Company or  Indemnitee
             in any  matter material  to either  such party  or (ii)  any
             other party to  the action,  suit, arbitration,  alternative
             dispute resolution mechanism, investigation,  administrative
             hearing or  any other  proceeding whether  civil,  criminal,
             administrative or investigative giving  rise to a claim  for
             indemnification hereunder.   Notwithstanding the  foregoing,
             the term "Independent Counsel" shall not include any  person
             who, under the applicable standards of professional  conduct
             then prevailing,  would  have  a  conflict  of  interest  in
             representing either the Company  or Indemnitee in an  action
             to determine Indemnitee's Rights under this Agreement.

             15.  Headings.   The  headings  of the  paragraphs  of  this
        Agreement are  inserted for  convenience only  and shall  not  be
        deemed to  constitute part  of this  Agreement or  to affect  the
        construction thereof.

             16.  Modification and Waiver.  This Agreement may be amended
        from time to time to reflect changes in Delaware law or for other
        reasons.   No  supplement,  modification  or  amendment  of  this
        Agreement shall be binding unless executed in writing by both  of
        the parties hereto.  No waiver  of any of the provisions of  this
        Agreement shall be  deemed or  shall constitute a  waiver of  any
        other provision hereof  (whether or not  similar) nor shall  such
        waiver constitute a continuing waiver.

             17.  Notice by Indemnitee.   Indemnitee  agrees promptly  to
        notify the Company in writing upon being served with any summons,
        citation, subpoena, complaint,  indictment, information or  other
        document  relating  to  any  matter  which  may  be  subject   to

        provided, however, that the failure to give any such notice shall
        not disqualify the indemnitee from indemnification hereunder.

        communications hereunder shall be in writing and shall be  deemed

    Thermo Vision Corporation                       1997 Financial Statements

                   Notes To Consolidated Financial Statements

    1.  Nature of Operations and Summary of Significant Accounting Policies

    Nature of Operations
        Thermo Vision Corporation (the Company) designs, manufactures, and
    markets a diverse array of photonics products, including optical
    components, imaging sensors and systems, lasers, optically based
    instruments, optoelectronics, and fiber optics. The Company sells
    photonics products in multiple markets across a number of industries for
    research, testing, detecting, and manufacturing applications. The
    Company's products range from optical filters used in blood glucose
    monitoring, to charge-injection devices (CIDs) used in optical
    spectroscopy, to specialty light sources used for quality assurance in
    semiconductor photolithography. Many of the Company's customers are
    manufacturers that incorporate the Company's products into medical and
    dental diagnostic instruments, analytical instruments, equipment for
    semiconductor manufacturing, and X-ray screening devices.

    Relationship with Thermo Optek Corporation, Thermo Instrument Systems
    Inc., and Thermo Electron Corporation
        The Company was incorporated in November 1995 as a wholly owned
    subsidiary of Thermo Optek Corporation at which time Thermo Optek
    transferred to the Company all of the assets, liabilities, and businesses
    of two subsidiaries of Thermo Jarrell Ash (TJA) in exchange for 6,908,785
    shares of the Company's common stock (adjusted to reflect a 55-for-54
    stock split distributed in December 1997 in the form of a stock
    dividend). The companies transferred were CID Technologies Inc. (CIDTEC)
    and Scientific Measurement Systems Inc., (now called Thermo Vision
    Colorado). In August 1997, the Company acquired the crystal-materials
    business (Hilger) of Hilger Analytical Limited, a wholly owned subsidiary
    of Thermo Optek, and accounted for the transaction at historical cost in
    a manner similar to a pooling of interests (Note 2). 
        In December 1997, Thermo Optek, a 91%-owned publicly traded
    subsidiary of Thermo Instrument Systems Inc., distributed to its
    shareholders 100% of the Company's common stock in the form of a
    dividend. Thermo Instrument is a publicly traded, majority-owned
    subsidiary of Thermo Electron Corporation. As of January 3, 1998, Thermo
    Instrument and Thermo Electron owned a total of 6,401,901 shares of the
    Company's common stock, representing 79.5% of such stock outstanding.

    Principles of Consolidation
        The accompanying financial statements include the accounts of the
    Company and its wholly owned subsidiaries. All material intercompany
    accounts and transactions have been eliminated.

    Fiscal Year
        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.

                   Notes To Consolidated Financial Statements

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

    Revenue Recognition
        The Company recognizes revenues upon shipment of its products. The
    Company provides a reserve for its estimate of warranty and installation
    costs at the time of shipment.
    Stock-based Compensation Plans
        The Company applies Accounting Principles Board Opinion (APB) No. 25,
    "Accounting for Stock Issued to Employees" and related interpretations in
    accounting for its stock-based compensation plans (Note 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
        The Company, Thermo Optek, and Thermo Instrument entered into tax
    allocation agreements under which the Company, Thermo Optek, and Thermo
    Instrument were included in Thermo Electron's consolidated federal and
    certain state income tax returns. The agreements provided that in years
    in which the Company had taxable income, it would pay to Thermo Electron
    amounts comparable to the taxes the Company would have paid if it had
    filed separate tax returns. Subsequent to the Company's initial public
    offering in December 1997, Thermo Instrument's equity ownership of the
    Company was reduced below 80% and, as a result, the Company is required
    to file its own federal and certain state income tax returns.
        In accordance with Statement of Financial Accounting Standards (SFAS)
    No. 109, "Accounting for Income Taxes," the Company recognizes deferred
    income taxes based on the expected future tax consequences of differences
    between the financial statement basis and the tax basis of assets and
    liabilities, calculated using enacted tax rates in effect for the year in
    which the differences are expected to be reflected in the tax return.

    Earnings per Share
        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 the 1996 and 1995 periods. Basic earnings per share have been
    computed by dividing net income by the weighted average number of shares
    outstanding during the year. For periods prior to the Company's November
    1995 capitalization, shares issued in connection with such capitalization
    have been shown as outstanding for purposes of computing earnings per
    share. Diluted earnings per share have been computed assuming the
    exercise of stock options, as well as their related income tax effects.
    Stock Splits
        All share and per share information, except for share information in
    the accompanying 1996 balance sheet, has been restated to reflect an
    approximate 55-for-54 stock split, effected in the form of a stock
    dividend, distributed in December 1997. The purpose of this stock split
    was to preserve a distribution ratio of 14 shares of the Company's common
    stock for each 100 shares of common stock held by Thermo Optek
    shareholders as of the date that Thermo Optek distributed the Company's
    common stock to its shareholders.

        (continued)

    Cash and Cash Equivalents
        As of January 3, 1998, $9,410,000 of the Company's cash equivalents
    were invested in a repurchase agreement with Thermo Electron. Under this
    agreement, the Company in effect lends excess cash to Thermo Electron,
    which Thermo Electron collateralizes with investments principally
    consisting of corporate notes, 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. The repurchase agreement earns a rate based on the 90-day
    Commercial Paper Composite Rate plus 25 basis points, set at the
    beginning of each quarter.

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

    Property, Plant, and Equipment
        The costs of additions and improvements are capitalized, while
    maintenance and repairs are charged to expense as incurred. The Company
    provides for depreciation and amortization using the straight-line method
    over the estimated useful lives of the property as follows: buildings, 30
    years; machinery and equipment, 3 to 10 years; and leasehold
    improvements, the shorter of the term of the lease or the life of the
    asset. Property, plant, and equipment consists of the following:

                   Notes To Consolidated Financial Statements

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

    Other Assets
        Other assets in the accompanying balance sheet consists primarily of
    a 10% ownership interest in LOT-Oriel Holding GmbH (LOT). The carrying
    amount of the investment, which is being accounted for under the cost
    method, is $500,000 in the accompanying 1997 balance sheet. 
        The Company has an investment of less than 20% in Andor Technology
    Limited. The carrying amount of the investment, which is being accounted
    for under the cost method, is $84,000 in the accompanying balance sheet.
    Prior to October 1996, the Company owned approximately 51% of Andor, and
    Andor's results were consolidated with those of the Company. During the
    third quarter of 1996, the Company reduced its ownership interest in
    Andor in a transaction with Andor's other stockholders. In consideration
    for the sale of a portion of its interest in Andor, the Company received
    approximately $159,000 in cash and a $147,000 principal amount 8% note,
    which was paid in September 1997. Andor's results were not material to
    the Company's results of operations.

    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 $718,000 and $371,000 at year-end 1997 and
    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 subsidiary 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 shareholder's 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, note payable, accounts payable,
    due to Thermo Electron and affiliated companies, and long-term
    obligations due to Thermo Optek and Thermo Electron. The Company's
    long-term obligations (Note 7) bear interest at a variable market rate
    and therefore the carrying amounts approximate fair value. The carrying
    amounts of the Company's remaining financial instruments approximate fair
    value due to their short-term nature.

                   Notes To Consolidated Financial Statements

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

    Use of Estimates
        The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities
    and disclosure of contingent assets and liabilities at the date of the
    financial statements, and the reported amounts of revenues and expenses
    during the reporting period. Actual results could differ from those
    estimates.

    2.  Acquisitions

        In August 1997, the Company acquired Hilger, a manufacturer of
    crystals used for X-ray scintillation and infrared spectroscopy, from
    Thermo Optek for the assumption of the short-term obligation discussed in
    Note 7. Because the Company and Hilger were deemed for accounting
    purposes to be under control of their common owner, Thermo Optek, the
    transaction has been accounted for at historical cost in a manner similar
    to a pooling of interests. Accordingly, the results of operations of
    Hilger are included for all periods presented. 
        In July 1997, the Company acquired the assets of Centronic, Inc. (now
    called Centro Vision, Inc.), a manufacturer of silicon photodiodes, for
    $3,800,000 in cash. The cost of this acquisition exceeded the estimated
    fair market value of the acquired net assets by $2,307,000. To finance
    this acquisition, the Company borrowed $3,800,000 from Thermo Electron
    (Note 7).
        In February 1997, the Company acquired all the outstanding stock of
    Laser Science, Inc. (LSI) for $3,600,000 in cash. LSI is a manufacturer
    of nitrogen and tunable dye lasers as well as pulsed CO2 lasers for
    industry, medicine, education, and defense. The cost of this acquisition
    exceeded the estimated fair market value of the acquired net assets by
    $2,836,000. To finance this acquisition, the Company borrowed $3,600,000
    from Thermo Optek (Note 7). In addition, the Company borrowed an
    additional $347,000 from Thermo Optek to fund certain property additions
    made in connection with the acquisition of LSI (Note 7).
        In February 1996, the Company acquired Oriel Corporation, a
    manufacturer and distributor of photonics components and instruments, for
    $11,798,000 in cash and the assumption of $731,000 in debt, and the
    assets of Corion Corporation, a manufacturer of commercial optical
    filters, for $5,072,000 in cash. The cost of Oriel and Corion exceeded
    the estimated fair market value of the acquired net assets by $4,736,000
    and $2,056,000, respectively.
        These acquisitions, except for Hilger, have been accounted for using
    the purchase method of accounting, and their results of operations have
    been included in the accompanying financial statements from the
    respective dates of acquisition.

    2.  Acquisitions (continued)

        In October 1994, Thermo Instrument acquired CIDTEC, a manufacturer of
    charge-injection devices used for image sensors and video cameras, for
    $3,401,000 in cash. The cost of this acquisition exceeded the estimated
    fair market value of the acquired net assets by $2,889,000. Thermo
    Instrument transferred the assets, liabilities, and businesses of CIDTEC
    to Thermo Optek after its formation in August 1995. Thermo Optek
    transferred the assets, liabilities, and businesses of CIDTEC to the
    Company after its formation in November 1995. Because the Company,
    CIDTEC, and Thermo Optek were deemed for accounting purposes to be under
    control of their common majority owner, Thermo Instrument, the
    accompanying financial statements include the results of operations of
    CIDTEC for all periods presented.
        Based on unaudited data, the following table presents selected
    financial information for the Company and the businesses acquired on a
    pro forma basis, assuming the Company, Centro Vision, and LSI had been
    combined since the beginning of 1996 and the Company, Oriel, and Corion
    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 Centro Vision and LSI been made at the beginning of 1996
    or the acquisitions of Oriel and Corion been made at the beginning of
    1995.

    3.  Employee Benefit Plans

    Stock-based Compensation Plans

    Stock Option Plans
    ------------------
        In November 1997, the Company adopted 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. To date, only nonqualified stock
    options have been awarded under this plan. The option recipients and the
    terms of options granted under this plan are determined by the Board
    Committee. Options granted to date became exercisable on March 10, 1998,
    and are subject to certain transfer restrictions and the right of the
    Company to repurchase shares issued upon exercise of the options at the
    exercise price, upon certain events. The restrictions and repurchase
    rights generally lapse ratably over a five- to ten-year period, depending
    on the term of the option, which generally ranges from seven to twelve
    years.

                   Notes To Consolidated Financial Statements

    3.  Employee Benefit Plans (continued)

    Nonqualified stock options may be granted at any price determined by the
    Board Committee, although incentive stock options must be granted at not
    less than the fair market value of the Company's stock on the date of
    grant. In addition to the Company's stock-based compensation plans,
    certain officers and key employees may also participate in the
    stock-based compensation plans of Thermo Electron and Thermo Instrument.
        A summary of the Company's stock option information for 1997 is as
    follows:

                                                                1997

        As of January 3, 1998, the options outstanding were exercisable at
    $7.50 and had a weighted average remaining contractual life of 6.8 years.

    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 Thermo Instrument. Under this program, shares of Thermo Instrument's
    and Thermo Electron's common stock can be purchased at the end of a
    12-month plan year at 95% of the fair market value at the beginning of
    the plan year, and the shares purchased are subject to a six-month resale
    restriction. Prior to November 1, 1995, the applicable shares of common
    stock could be purchased at 85% of the fair market value at the beginning
    of the plan year, and the shares purchased were subject to a one-year
    resale restriction. Shares are purchased through payroll deductions of up
    to 10% of each participating employee's gross wages.

    3.  Employee Benefit Plans (continued)

    Pro Forma Stock-based Compensation Expense
        In October 1995, the Financial Accounting Standards Board issued SFAS
    No. 123, "Accounting for Stock-based Compensation," which sets forth a
    fair-value based method of recognizing stock-based compensation expense.
    As permitted by SFAS No. 123, the Company has elected to continue to
    apply APB No. 25 to account for its stock-based compensation plans. Had
    compensation cost for awards granted in 1997 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
    ----------------------------------------------------------------------
    Net income:
      As reported                                                   $2,348
      Pro forma                                                      2,270

    Basic and diluted earnings per share:
      As reported                                                      .34
      Pro forma                                                        .33

        Compensation expense for options granted is reflected over the
    vesting period; therefore, future pro forma compensation expense may be
    greater as additional options are granted.
        The weighted average fair value per share of options granted in 1997
    was $2.69. The fair value of each option grant was estimated on the grant
    date using the Black-Scholes option-pricing model with the following
    weighted-average assumptions:

                                                                      1997
    ----------------------------------------------------------------------
    Volatility                                                         28%
    Risk-free interest rate                                           6.0%
    Expected life of options                                     4.9 years

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

    401(k) Savings Plans
        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 plans are made by both the employee
    and the Company. Company contributions are based upon the level of
    employee contributions. For these plans, the Company contributed and
    charged to expense $212,000, $182,000, and $39,000 in 1997, 1996, and
    1995, respectively. 

    4.  Common Stock

        In December 1997, the Company sold 1,139,491 shares of its common
    stock in an initial public offering at $7.50 per share for net proceeds
    of $7,033,000.
        At January 3, 1998, the Company had reserved 725,000 unissued shares
    of its common stock for possible issuance under stock-based compensation
    plans.

    5.  Income Taxes

        The components of income before provision for income taxes are as

    was acquired in 1997, had tax loss carryforwards that the Company is not

    to offset future taxable income of LSI through the year 2008.

    5.  Income Taxes (continued)

        A provision has not been made for U.S. or additional foreign taxes on
    $1,006,000 of undistributed earnings of the Company's foreign subsidiary
    that could be subject to taxation if remitted to the U.S. because the
    Company plans to keep this amount permanently reinvested overseas.

    6.  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 $659,000, $438,000, and
    $120,000 in 1997, 1996, and 1995, respectively. Future minimum payments
    due under noncancellable operating leases at January 3, 1998, are
    $560,000 in 1998; $550,000 in 1999; $484,000 in 2000; $376,000 in 2001;
    $398,000 in 2002; and $1,864,000 in 2003 and thereafter. Total future
    minimum lease payments are $4,232,000. The Company also has operating
    lease arrangements with related parties as discussed in Note 7.

    7.  Related-party Transactions

    Corporate Services Agreement
        The Company and Thermo Electron have a corporate services agreement
    under which Thermo Electron's corporate staff provides certain
    administrative services, including certain legal advice and services,
    risk management, certain employee benefit administration, tax advice and
    preparation of tax returns, centralized cash management, and certain
    financial and other services, for which the Company paid Thermo Electron
    annually an amount equal to 1.0% of the Company's revenues in 1997 and
    1996 and 1.2% of the Company's revenues in 1995. For these services, the
    Company was charged $397,000, $304,000, and $72,000 in 1997, 1996, and
    1995, respectively. Beginning in 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 charged by Thermo Electron is reasonable and that
    such fees are representative of the expenses the Company would have
    incurred on a stand-alone basis. The corporate services agreement is
    renewed annually but can be terminated upon 30 days' prior notice by the
    Company or upon the Company's withdrawal from the Thermo Electron
    Corporate Charter (the Thermo Electron Corporate Charter defines the
    relationship among Thermo Electron and its majority-owned subsidiaries).
    For additional items such as employee benefit plans, insurance coverage,
    and other identifiable costs, Thermo Electron charges the Company based
    upon costs attributable to the Company.

    Operating Leases
        In addition to the operating leases described in Note 6, the Company
    leases certain office and manufacturing space on a monthly basis from
    Thermo Optek and Thermo Instrument. The accompanying statement of income
    includes expenses from these arrangements of $238,000, $297,000, and
    $91,000 in 1997, 1996, and 1995, respectively. Prior to January 1, 1997,
    rent expense under these arrangements was determined as the Company's

    allocated share of total occupancy expenses. Subsequently, the Company
    pays fixed monthly rates. Effective for 1998, the annual rent under the
    lease with Thermo Optek is $45,000. At January 3, 1998, future minimum
    payments due under the lease with Thermo Instrument, which expires in
    January 2006, are $213,000 in 1998; $223,000 in 1999; $234,000 in 2000;
    $240,000 in 2001; $250,000 in 2002; and $835,000 in 2003 and thereafter.
    Total future minimum lease payments are $1,995,000.

    Long-term Obligations
        The Company borrowed funds from Thermo Electron and Thermo Optek to
    finance the acquisitions of certain companies (Note 2). In connection
    with the July 1997 acquisition of Centro Vision, the Company borrowed
    $3,800,000 from Thermo Electron pursuant to a promissory note due July
    2000. In connection with the February 1997 acquisition of LSI and certain
    related property additions, the Company borrowed $3,947,000 from Thermo
    Optek pursuant to promissory notes due February 2000. These notes bear
    interest at the 90-day Commercial Paper Composite Rate plus 25 basis
    points, set at the beginning of each quarter. The interest rate for the
    notes at year-end 1997 was 5.76%.

    Short-term Obligation
        Note payable in the accompanying balance sheet represents short-term
    bank borrowings at the Company's foreign subsidiary. The Company has an
    arrangement under which it may borrow on a bank line of credit
    arrangement held by Thermo Optek. The interest rate for these borrowings
    was 8.00% and 6.75% at year-end 1997 and 1996, respectively. Availability
    to the Company under this line of credit totaled $2,042,000 as of January
    3, 1998.

    Distribution Agreement with LOT
        The Company has a distribution agreement with LOT which allows LOT to
    be Oriel's primary distributor in certain parts of Europe. Sales to LOT
    included in the accompanying 1997 and 1996 statements of income were
    $2,122,000 and $1,952,000, respectively. Accounts receivable in the
    accompanying balance sheet includes $608,000 and $442,000 due from LOT at
    year-end 1997 and 1996, respectively.

    Trademark License and Royalty Agreement
        In September 1996, the Company agreed to license the use of a
    trademark to Andor in exchange for a fee equal to the greater of 3.3% of
    the net sales revenue, as defined, from sales of products sold under the
    trade name, or 10,000 British pounds sterling. In 1997 and 1996, the
    Company recorded revenues of $91,000 and $15,000, respectively, under
    this agreement.

    Contract Research and Development
        In 1997, 1996, and 1995, the Company recorded revenues of $80,000,
    $188,000, and $418,000, respectively, from Thermo Optek for contract
    research and development services related to components used in certain
    products manufactured by Thermo Optek.

    Thermo Vision Corporation                       1997 Financial Statements

                    Report of Independent Public Accountants

    To the Shareholders and Board of Directors of Thermo Vision Corporation:

        We have audited the accompanying consolidated balance sheet of Thermo
    Vision Corporation (a Delaware corporation and 78%-owned subsidiary of
    Thermo Instrument Systems 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 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 provide a reasonable basis for
    our opinion.
        In our opinion, the consolidated financial statements referred to
    above present fairly, in all material respects, the financial position of
    Thermo Vision Corporation 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 period ended January 3, 1998, in
    conformity with generally accepted accounting principles.

        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

    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

    Overview

        The Company designs, manufactures, and markets a diverse array of
    photonics products, including optical components, imaging sensors and
    systems, lasers, optically based instruments, optoelectronics, and fiber
    optics. The Company sells photonics products in multiple markets across a
    number of industries for research, testing, detecting, and manufacturing
    applications.
        The Company initially comprised two businesses: Scientific
    Measurement Systems Inc. (now called Thermo Vision Colorado), a
    manufacturer of optically based instruments, and CID Technologies Inc.
    (CIDTEC), a manufacturer of sensors and cameras based on proprietary
    charge-injection device (CID) technology. Since February 1996, the
    Company has acquired four businesses from unrelated third parties that
    currently constitute the bulk of its operations. In February 1996, the
    Company acquired Oriel Corporation, a manufacturer and distributor of
    photonics components and instruments, and Corion Corporation, a
    manufacturer of commercial optical filters. In February 1997, the Company
    acquired Laser Science, Inc. (LSI), a manufacturer of gas lasers. In July
    1997, the Company acquired Centronic Inc. (now called Centro Vision,
    Inc.), a manufacturer of silicon photodiodes. In addition, in August
    1997, the Company acquired the crystal-materials business (Hilger) of
    Hilger Analytical Limited, a wholly owned subsidiary of Thermo Optek
    Corporation. Because the Company and Hilger were deemed for accounting
    purposes to be under control of their common owner, Thermo Instrument
    Systems Inc., the transaction has been accounted for at historical cost
    in a manner similar to a pooling of interests. Accordingly, the results
    of operations of Hilger are included for all periods presented. From the
    time of the Company's incorporation in November 1995 to August 1997, the
    crystal-materials business of Hilger Analytical was under the Company's
    management. 
        Approximately 7% of the Company's 1997 revenues originated outside
    the U.S. and approximately 27% of the Company's 1997 revenues were
    exports from the U.S. Revenues originating outside the U.S. represent
    revenues of Hilger. Hilger's operations are located in the United Kingdom
    and principally sell in the local currency. Exports from the Company's
    U.S. operations are denominated in U.S. dollars. Although the Company

                  Financial Condition and Results of Operations

    Overview (continued)

    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.

    Results of Operations

    1997 Compared With 1996
        Revenues increased 30% to $39.7 million in 1997 from $30.4 million in
    1996. Revenues increased $9.2 million due to the inclusion of revenues
    from LSI, acquired in February 1997, and Centro Vision, acquired in July
    1997, and the inclusion of revenues for the full year from Oriel and
    Corion, acquired in February 1996. Revenues increased at Hilger due to
    shipments under its Stanford Linear Accelerator contract, which commenced
    in the second quarter of 1996. This increase was offset in part by lower
    revenues at Oriel because the Company is no longer consolidating the
    results of Andor Technology Limited (Note 1).
        The gross profit margin was unchanged at 44% in 1997 and 1996.
        Selling, general, and administrative expenses as a percentage of
    revenues decreased to 23% in 1997 from 24% in 1996, due primarily to
    lower selling and marketing expenses at Oriel during the year. Research
    and development expenses increased to $4.1 million in 1997 from $3.5
    million in 1996, due primarily to the inclusion of research and
    development expenses at LSI and Centro Vision.
        Interest expense of $0.3 million in 1997 primarily represents
    interest incurred on the $3.6 million and $3.8 million promissory notes
    issued to Thermo Optek and Thermo Electron Corporation, respectively, for
    the acquisitions of LSI and Centro Vision, respectively.
        The effective tax rate was 42% in 1997 and 41% in 1996. The effective
    tax rates exceeded the statutory federal income tax rate due primarily to
    the impact of nondeductible amortization of cost in excess of net assets
    of acquired companies and 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 purchased by the
    Company. The Company believes that its internal information systems 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, which could result
    in a material adverse effect on the Company's future results of
    operations.
        The Company is presently 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
    products purchased from key suppliers is not reasonably likely to have a
    material adverse effect on the Company's future results of operations.

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

    1996 Compared With 1995
        Revenues increased to $30.4 million in 1996 from $6.0 million in
    1995, due primarily to the inclusion of $24.2 million of revenues from
    Oriel and Corion, acquired in February 1996. Revenues from the Company's
    existing operations increased $0.2 million, due primarily to the
    inclusion of a $0.5 million nonrecurring sale at CIDTEC, offset in part
    by decreased revenues at Thermo Vision Colorado due to lower demand.
        The gross profit margin increased to 44% in 1996 from 42% in 1995,
    due primarily to the inclusion of higher-margin revenues at Oriel, offset
    in part by the inclusion of lower-margin revenues at Corion. 
        Selling, general, and administrative expenses as a percentage of
    revenues decreased to 24% in 1996 from 25% in 1995, due primarily to
    lower costs as a percentage of revenue at acquired businesses. Research
    and development expenses increased to $3.5 million in 1996 from $0.7
    million in 1995, due primarily to the inclusion of $2.5 million of
    research and development expenses at acquired businesses. 
        Interest expense in both periods represents interest incurred on
    short-term borrowings at Hilger.
        The effective tax rate was 41% in 1996 and 1995. The effective tax
    rates exceeded the statutory federal income tax rate due primarily to the
    impact of nondeductible amortization of cost in excess of net assets of
    acquired companies in both years and state income taxes in 1996.

    Liquidity and Capital Resources
        Consolidated working capital was $19.6 million at January 3, 1998,
    compared with $5.6 million at December 28, 1996. Included in working
    capital are cash and cash equivalents of $9.6 million at January 3, 1998,
    compared with $0.3 million at December 28, 1996. In 1997, operating
    activities provided $3.3 million of cash. The Company used $0.6 million
    to fund an increase in inventory, primarily to support CIDTEC's new
    dental imaging sensor, which was introduced in the first quarter of 1998.
        The Company's investing activities used $8.9 million of cash during
    1997, due primarily to $7.3 million, net of cash acquired, used to
    acquire businesses (Note 2). The Company expended $1.5 million on
    purchases of property, plant, and equipment during 1997 and plans to
    expend approximately $1.9 million on such purchases during 1998.
        The Company's financing activities provided $14.9 million of cash
    during 1997, due primarily to borrowings of $7.7 million for acquisitions
    (Note 2) and proceeds of $7.0 million from the Company's December 1997
    initial public offering of common stock.
        Hilger, the Company's foreign subsidiary, has a credit facility
    arrangement for working capital needs (Note 7). Although the Company
    generally expects to have positive cash flow from its existing
    operations, the Company may require significant amounts of cash for any
    acquisition of complementary businesses. The Company expects that it will
    finance any such acquisitions through internal funds, additional debt or
    equity financing from capital markets, or short- or long-term borrowings
    from Thermo Instrument or Thermo Electron, although it has no agreement
    with these companies to ensure that additional funds will be available on
    acceptable terms or at all. The Company believes its existing resources
    are sufficient to meet the capital requirements of its existing
    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.

        Risks Associated with Technological Change, Obsolescence, and the
    Development and Acceptance of New Products. The market for the Company's
    products is characterized by rapid and significant technological change
    and evolving industry standards. New product introductions responsive to
    these factors require significant planning, design, development, and
    testing at the technological, product, and manufacturing process levels,
    and may render existing products and technologies uncompetitive or
    obsolete. There can be no assurance that the Company's products will not
    become uncompetitive or obsolete. In addition, industry acceptance of new
    applications for the Company's technologies developed by the Company may
    be slow to develop due to, among other things, the general unfamiliarity
    of users with new applications and technologies. There can be no
    assurance that these factors will not have a material adverse effect on
    the Company's results of operations, financial condition, or business.

        Risks Associated with Acquisition Strategy; No Assurance of a
    Successful Acquisition Strategy. One of the Company's growth strategies
    is to supplement its internal growth with the acquisition of businesses
    and technologies that complement or augment the Company's existing
    product lines. Since February 1996, the Company has acquired four
    businesses from unrelated third parties that comprise the bulk of its
    operations. Certain businesses that the Company may seek to acquire in
    the future may be marginally profitable or unprofitable. In order for any
    acquired businesses to achieve the level of profitability desired by the
    Company, the Company must successfully reduce expenses and improve market
    penetration. No assurance can be given that the Company will be
    successful in this regard. In many instances, acquisitions by the Company
    will result in the Company recording cost in excess of net assets of
    acquired companies on its balance sheet. Such cost in excess of net
    assets of acquired companies will be amortized as a noncash expense over
    specified periods. In addition, 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. These factors may adversely affect both the
    availability and price of prospective acquisition targets. There can be
    no assurance that the Company will be able to complete pending or future
    acquisitions. In order to finance any acquisitions, it may be necessary
    for the Company to raise additional funds through additional 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 may result in
    dilution to the Company's shareholders. In the past, a significant
    portion of the funding for the Company's acquisitions has come from
    Thermo Optek, Thermo Instrument, or Thermo Electron. Although Thermo
    Electron and Thermo Instrument regularly fund acquisitions by their

                                       25PAGE

                           Forward-looking Statements

    respective wholly and partially owned subsidiaries, neither Thermo
    Electron nor Thermo Instrument has committed to fund any future
    acquisitions by the Company. There can be no assurance that the Company
    will be able to secure any such financing or that these factors will not
    have a material adverse effect on the Company's results of operations,
    financial condition, or business.

        Intense Competition. The Company encounters and expects to continue
    to encounter intense competition in the sale of its products. The Company
    believes that the principal competitive factors affecting the market for
    its products include product performance, price, reliability, and
    customer service. The Company's principal competitors include
    Melles-Griot, Inc.; Optical Coating Laboratory, Inc.; Newport
    Corporation; Coherent, Inc.; Corning OCA Corporation; the Bicron Business
    Unit of Saint-Gobain Industrial Ceramics, Inc.; Hamamatsu Corporation, a
    unit of Hamamatsu Photonic KK; and UDT Sensors, Inc., an Opto-Sensors
    Company. Certain of these companies and certain of the Company's other
    competitors have substantially greater financial, marketing, and other
    resources than those of the Company. As a result, they may be able to
    adapt more quickly to new or emerging technologies and changes in
    customer requirements or to devote greater resources to the promotion and
    sale of their products than the Company. In addition, competition could
    increase if new companies enter the market or if existing competitors
    expand their product lines or intensify efforts within existing product
    lines. There can be no assurance that the Company's current products,
    products under development, or ability to discover new technologies will
    be sufficient to enable it to compete effectively with its competitors.
    In addition, there can be no assurance that these factors will not have a
    material adverse effect on the Company's results of operations, financial
    condition, or business.

        Possible Adverse Impact of Significant International Sales. Sales
    outside the United States account for a significant portion of the
    Company's revenues, and the Company expects that international sales will
    continue to account for a significant portion of its revenues in the
    future. Sales to customers in foreign countries are subject to a number
    of risks, including the following: agreements may be difficult to enforce
    and receivables difficult to collect through a foreign country's legal
    system; foreign customers may have longer payment cycles; foreign
    countries could impose 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 provided
    by the Company in foreign markets where payment for the Company's
    products 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. There can be no
    assurance that any of these factors will not have a material adverse
    effect on the Company's results of operations, financial condition, or
    business.

                           Forward-looking Statements

        Risks Associated with Protection, Defense, and Use of Intellectual
    Property. The Company holds a number of patents relating to various
    aspects of its products and believes that proprietary technical know-how
    is critical to many of its products. Proprietary rights relating to the
    Company's products are 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 that patents will issue from any pending or future patent
    applications owned by or licensed to the Company or that the claims
    allowed under any issued patents will be sufficiently broad to protect
    the Company's technology. In the absence of patent protection, the
    Company may be vulnerable to competitors who attempt to copy the
    Company's products or gain access to its trade secrets and know-how.
    Proceedings initiated by the Company to protect its proprietary rights
    could result in substantial costs to the Company. There can be no
    assurance that competitors of the Company will not initiate litigation to
    challenge the validity of the Company's patents or that they will not use
    their resources to design comparable products that do not infringe the
    Company's patents. There may also be pending or issued patents held by
    parties not affiliated with the Company that relate to the Company's
    products or technologies. The Company may need to acquire licenses to, or
    contest the validity of, any such patents. There can be no assurance that
    any license required under any such patent would be made available on
    acceptable terms, if at all, or that the Company would prevail in any
    such contest. The Company could incur substantial costs in defending
    itself in suits brought against it or in suits in which the Company may
    assert its patent rights against others. If the outcome of any such
    litigation is unfavorable to the Company, the Company's results of
    operations, financial condition, and business could be materially
    adversely affected. In addition, the Company relies on trade secrets and
    proprietary know-how which it seeks to protect, in part, by
    confidentiality agreements with its collaborators, employees, and
    consultants. There can be no assurance that these agreements will not be
    breached, that the Company would have adequate remedies for any breach,
    or that the Company's trade secrets will not otherwise become known or be
    independently developed by competitors.

        Potential Fluctuations in Quarterly Performance. The Company's
    quarterly operating results may vary significantly depending on a number
    of factors, including the timing of product development and introduction;
    size, timing, and shipment of individual orders; seasonality of revenue;
    foreign currency exchange rates; the mix of products sold; and general
    economic conditions. 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.

        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 purchased by

    the Company. The Company believes that its internal information systems
    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

    which could result in a material adverse effect on the Company's future
    results of operations.

    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
    products purchased from key suppliers is not reasonably likely to have a
    material adverse effect on the Company's future results of operations.
