                                    PART I


  Item 1.  Business

  (a)  General Development of Business.

       Thermo Instrument Systems Inc. (the Company or the Registrant) is a
  worldwide leader in the development, manufacture, and marketing of
  analytical instruments used to detect and measure air pollution, nuclear
  radioactivity, complex chemical compounds, toxic metals, and other elements
  in a wide variety of materials. The Company also markets process monitoring
  and control instruments primarily for the oil, gas, and petrochemical
  industries. Through its 86%-owned subsidiary, ThermoSpectra Corporation
  (ThermoSpectra), the Company develops, manufactures, and markets precision
  imaging, inspection, and measurement instrumentation that employ a variety
  of energy sources or signals as well as high-speed data acquisition and
  digital processing technologies. In 1994, the Company's ThermoSpectra
  subsidiary sold 1,505,000 shares of its common stock in private placements
  at $10.00 per share for net proceeds of $14.0 million, resulting in a gain
  of $6.5 million.

        Effective April 4, 1994, the Company formed an environmental services
  joint venture with Thermo Process Systems Inc. (Thermo Process), another
  public subsidiary of Thermo Electron Corporation (Thermo Electron). The
  joint venture operates under the name Thermo Terra Tech. The Company
  contributed the analytical laboratories and the nuclear health physics and
  environmental science and engineering services businesses that comprised
  its Services segment. Thermo Process contributed its environmental
  laboratory business, which specializes in fast-response testing of
  petroleum-contaminated soils and groundwater, and approximately $31 million
  in cash and short-term investments.

       The Company owns 49% of Thermo Terra Tech and accounts for its
  interest in the joint venture using the equity method. As a result, the
  Services segment operations are no longer consolidated in the Company's
  financial statements. Under the terms of the joint venture agreement,
  66.67% of income earned by the joint venture after April 4, 1994, will be
  allocated to the Company until the first to occur of (a) the joint venture
  has accumulated $5.1 million in net profits, (b) April 1, 1995, or (c) the
  date on which at least 70% of Thermo Process' cash contribution to the
  joint venture is first invested in one or more additional businesses.
  Thereafter, the Company's share of the joint venture's income will be 49%.

       The Company historically has expanded both through the acquisition of
  companies and product lines and through internal development of new
  products and technologies. During the past several years the Company has
  completed several complementary acquisitions that have provided additional
  technologies, specialized manufacturing or product development expertise,
  and broader capabilities in marketing and distribution. In 1994*, the
  Company's acquisitions included the assets of IRT Corporation for a
  purchase price of $7.3 million, and several businesses within the
  EnviroTech Measurements & Controls group of Baker Hughes Incorporated
  (Baker Hughes) for a purchase price of $89.7 million. On January 1, 1995,
  the Company acquired the assets of the Analytical Instruments Division of

  * References to 1994, 1993, and 1992 herein are for the fiscal years ended
    December 31, 1994, January 1, 1994, and January 2, 1993, respectively.
                                       2PAGE
<PAGE>
  Baird Corporation, a wholly owned subsidiary of Imo Industries Inc., for
  $12.3 million in cash, subject to a post-closing adjustment. On March 1,
  1995, the Company entered into an Asset and Stock Purchase Agreement (the
  Agreement) with Fisons plc (Fisons) under which the Company agreed to
  acquire the Scientific Instruments Division (the Division) of Fisons for
  202 million British pounds sterling. The Division is principally composed
  of operations that are involved in the research, development, manufacture,
  and sale of analytical instruments to industrial and research laboratories
  worldwide. Consummation of the acquisition is subject to several
  conditions, including approval by Fisons shareholders, regulatory
  approvals, consent of certain third parties, and customary conditions to
  closing. The Company intends to fund the purchase price from available cash
  and through borrowings from Thermo Electron. Thermo Electron has guaranteed
  the obligations of the Company under the Agreement. The purchase price is
  subject to a post-closing adjustment based on the net asset value of the
  Division as of the closing date.

       The Company was incorporated in Delaware in May 1986 as a wholly owned
  subsidiary of Thermo Electron to succeed the instruments businesses that
  were previously conducted by several Thermo Electron subsidiaries. As of
  December 31, 1994, Thermo Electron owned 39,634,271 shares, or 83%, of the
  Company's outstanding common stock. Thermo Electron is a major manufacturer
  of biomedical products including heart-assist systems and mammography
  systems, papermaking and recycling equipment, alternative-energy systems,
  industrial process equipment, and other specialized products. Thermo
  Electron also provides environmental and metallurgical services and
  conducts advanced technology research and development. 

       Thermo Electron intends, for the foreseeable future, to maintain at
  least 80% ownership of the Company, so that it may continue to file
  consolidated U.S. federal and state income tax returns with the Company.
  This may require the purchase by Thermo Electron of additional shares of
  common stock and/or convertible debentures of the Company from time to time
  as the number of outstanding shares of the Company increases. These and any
  other purchases may be made either on the open market or directly from the
  Company or pursuant to conversions of the Company's 7% subordinated
  convertible note due 1996 or the 3 3/4% senior convertible note due 2000
  held by Thermo Electron. See Notes 5 and 11 to Consolidated Financial
  Statements in the Registrant's 1994 Annual Report to Shareholders for a
  description of the Company's outstanding stock options and convertible
  obligations. During 1994, Thermo Electron purchased 1,931,327 shares of the
  Company's common stock on the open market at a total cost of $57.4 million.

  (b)  Financial Information About Industry Segments.

       The Company operates in one business segment: the manufacturing and
  marketing of analytical, monitoring, and process control instruments used
  to detect and measure air pollution, radioactivity, complex chemical
  compounds, toxic metals and other elements in a broad range of liquids and
  solids, as well as to control and monitor various industrial processes
  (the Instruments Segment). Prior to April 4, 1994, the Company also
  provided environmental science and engineering services, laboratory-based
  testing, and nuclear physics services, which comprised the Company's
  Services segment. These services are now being provided by the Thermo Terra
  Tech joint venture.

       Financial information concerning the Company's industry segments is
  provided in Note 13 to Consolidated Financial Statements in the
  Registrant's 1994 Annual Report to Shareholders and is incorporated herein
  by reference.

  (c)  Description of Business.

       (i)  Principal Products and Services

       Instruments manufactured and marketed by the Company employ a variety
  of advanced technologies and spectral, electroanalytical, and separation
  techniques to determine the composition, structure, and physical properties
  of natural and synthetic substances. The Company's instruments can be
  broadly categorized by their use as analytical, monitoring, or process
  control instruments.

  Analytical Instruments

       The Company's principal analytical instrument products are atomic
  emission and absorption spectrometers, Fourier transform infrared (FT-IR)
  and FT-Raman spectrometers, mass spectrometers, high performance liquid
  chromatographs, gas chromatographs, and X-ray fluorescence instrumentation.

       Atomic Emission (AE) and Atomic Absorption (AA) Spectrometers identify
  and measure trace quantities of metals, and other elements in a wide
  variety of materials, including environmental samples (such as soil, water,
  and wastes), foods, drugs, cosmetics, and alloys. The Company sells its
  products to a wide range of customers in manufacturing industries such as
  producers of aircraft, automobiles and trucks, computers, chemicals, food,
  pharmaceuticals, and primary metals; service industries such as waste
  management companies and commercial testing laboratories; and government
  and university laboratories.

       The Company is a leading manufacturer of sequential AE spectrometers,
  in which elements are analyzed one at a time, and simultaneous AE
  spectrometers, in which many elements can be measured at the same time. The
  Company produces AA spectrometers in single-, double- and four-channel
  models. The Company is the only major producer of multichannel AA
  spectrometers, which provide several operational advantages over
  single-channel instruments, including speed of analysis, increased
  accuracy, reduced sample consumption, and analysis over an extended range
  of concentrations.

       The Company's FT-IR and FT-Raman spectrometers are designed to
  nondestructively determine the chemical composition and physical properties
  of materials. These instruments are used in many areas of chemical
  research, industrial quality control and process monitoring, and for
  solving a wide variety of materials analysis problems. The Company offers a
  variety of models ranging from newly introduced models designed for routine
  applications to highly advanced research-grade FT-IR spectrometers.

       The Company is a leading manufacturer of commercial mass spectrometers
  and has pioneered many of the significant developments and applications of
  mass spectrometry. The Company's mass spectrometry products identify and
  measure the components of a sample for organic chemical compounds or for
  inorganic compounds. These instruments are used by customers in
  environmental analysis and pollution control; in research and production of
  pharmaceuticals; in biochemistry; in analysis of foods, chemicals, and
                                       4PAGE
<PAGE>
  petrochemicals; and in health and forensic science. The Company provides
  both stand-alone mass spectrometers and combined systems that use its own
  chromatographs or those purchased from other companies. These products span
  a range of sensitivity, specificity, separation technologies, data-handling
  capabilities, sizes, and prices.

       The Company sells high performance liquid chromatography, capillary
  electrophoresis, and related instruments and equipment used principally in
  the research and development and production monitoring of pharmaceuticals,
  chemicals, and personal-care products, and for environmental monitoring.
  These instruments separate the chemical components of substances for
  purposes of identification and measurement. Capillary electrophoresis is a
  relatively new separation technique that is based on a combination of
  chromatographic and electroanalytical technologies and is particularly
  useful in biochemical, pharmaceutical, and environmental research.

       In 1994, with its acquisition of the Tremetrics and TN Technologies
  businesses from Baker Hughes, the Company added two analytical testing
  technologies: gas chromatography and X-ray fluorescence. Gas chromatographs
  are widely used in environmental and industrial laboratories as stand-alone
  instruments or in conjunction with mass spectrometers, where the gas
  chromatograph separates a sample into individual chemical components for
  the mass spectrometer to identify. Applications include the identification
  of organic compounds, from pesticide residues on vegetables to chlorinated
  organics in drinking water. The Company sells a wide variety of gas
  chromatography detectors that measure trace levels of pollutants in water,
  soil, and air. X-ray fluorescence instruments allow for the nondestructive
  analysis of inorganic elements. Applications include alloy identification,
  on-line process monitoring and quality control, characterization of toxic
  metals in soil, and thickness and/or composition of semiconductor thin
  films. In addition, the Company manufactures and markets digital
  oscilloscopes, multichannel transient recorders, high-resolution waveform
  analyzers, laser scanning confocal microscopes, and X-ray microanalysis
  equipment, as well as X-ray imaging systems used for quality assurance and
  failure analysis applications primarily in the electronics industry.

  Monitoring Instruments

       The Company manufactures monitoring instruments for two principal
  markets: the detection and measurement of nuclear radiation, and the
  monitoring of air pollutants including toxic and combustible gases.

       The Company's nuclear radiation monitoring instruments detect and
  measure alpha, beta, gamma, neutron, and X-ray radiation emitted by natural
  sources and by radioactive materials used in nuclear power plants and
  certain governmental, industrial, and medical facilities. The Company is a
  leading manufacturer of a broad range of stand-alone and portable
  instruments and computer-integrated instrument systems used to ensure the
  safety of personnel from exposure to nuclear radiation. Nuclear power
  plants and U.S. Department of Energy (DOE) facilities purchase
  approximately 70% of the radiation monitoring instruments sold by the
  Company. The businesses acquired from FAG Kugelfischer Georg Shafer AG in
  1993 provide two classes of products. The radiation safety-measurement
  products division is a major supplier of instruments and systems that are
  manufactured to European standards for personnel protection and
  environmental monitoring. The radiometry division manufactures industrial
  gauging and process control instruments used principally by manufacturers

                                       5PAGE
<PAGE>
  of flat sheet materials, including metals, plastics, rubber, paper, and
  fibers.

       The Company's air-monitoring instruments measure pollutants in ambient
  air and from stationary sources such as industrial smokestacks. The
  principal pollutants measured are oxides of nitrogen, sulfur dioxide,
  carbon monoxide, ozone, and volatile organic compounds (VOCs). These
  instruments are used by utility and industrial customers to ensure
  compliance with environmental regulations, by government agencies to
  monitor air quality, and by research facilities. The Occupational Safety
  and Health Administration's safety requirements for protecting workers from
  toxic or explosive atmospheres in confined spaces are addressed with the
  Company's detectors, instruments, and systems for sensing, monitoring, and
  warning of such dangers. These worker-safety products are used in a wide
  range of applications, from large petrochemical plants, utilities, and
  industrial manufacturing facilities to commercial buildings.

       In addition, the Company manufactures equipment that provides on-line,
  real-time analysis of elements in bulk raw materials, such as coal and
  cement. These analyzers are used by utilities to determine the sulfur
  content of coal to ensure compliance with air quality standards and by the
  cement industry to test raw materials to assure product quality and
  uniformity.

  Process Control Instruments

       With the 1994 acquisition of the EnviroTech Controls business from
  Baker Hughes, the Company now addresses the process monitoring, analysis,
  gauging, and control instruments market, primarily for the oil, gas, and
  petrochemical industries.

       The Company manufactures and markets a number of process monitoring,
  analysis, and control systems including: analog and digital recorders for
  continuous process industries; process and laboratory analytical
  instruments and monitors to detect lethal gases for the oil, gas, and
  petrochemical industries; supervisory control and data acquisition software
  for process monitoring and operator interface in a variety of industrial
  processes; and turnkey, integrated systems to control networks of distant
  oil and gas wells.

       The Company also manufactures and markets process gauges and
  noncontacting and nonintrusive process control instrumentation to measure
  liquid levels, density, weight, and flows for a variety of industries.
  Application examples include measuring levels in a pharmaceutical reactor,
  determining the percentage by weight of solids contained in a mining
  slurry, or monitoring the flow of fluid into a wastewater treatment
  facility. 

       In addition to analytical, monitoring, and process control
  instruments, the Company supplies related accessories, spare parts, and
  instrument maintenance and training programs at its own and its customers'
  facilities.

  Thermo Terra Tech Joint Venture

       Effective April 4, 1994, the Company formed an environmental services
  joint venture with Thermo Process Systems Inc., another public subsidiary
  of Thermo Electron. The Company contributed the analytical laboratories and
                                       6PAGE
<PAGE>
  the nuclear health physics and environmental science and engineering
  services businesses that comprised its Services segment. Thermo Process
  contributed its environmental laboratory business, which specializes in
  fast-response testing of petroleum-contaminated soils and groundwater, and
  approximately $31 million in cash and short-term investments. The Company
  owns 49% of Thermo Terra Tech and accounts for its interest in the joint
  venture using the equity method.

       Thermo Terra Tech provides comprehensive laboratory-based
  environmental testing, analysis, and related services for the detection,
  measurement, and monitoring of hazardous wastes and radioactive materials.
  Thermo Terra Tech's services also include design and construction
  inspection of water supply and wastewater treatment facilities, surveying
  and site planning, transportation engineering services, solid waste
  management services, and building services.

  Customers and Marketing

       The Company sells many of its products and services to customers whose
  activities are subject to numerous environmental quality, pollution
  control, and occupational safety and health regulations and laws enacted by
  federal, state, and local governments and by international accord.
  Customers include industrial manufacturers, environmental laboratories,
  utilities, waste management and treatment facilities, and government
  agencies. The Company's analytical instruments are also used in biomedical
  applications such as analysis of drugs and drug metabolites; in academic
  and industrial chemical research; in forensic science; in energy and
  mineral resource exploration and production; in metals processing; and in a
  range of product quality assurance and process monitoring applications. The
  Company's process control instrumentation is used primarily in the oil,
  gas, and petrochemical industries. 

       The Company sells its products through its own marketing and sales
  force in North America, Europe, and Asia and receives additional market
  coverage through authorized representatives throughout the world. Some
  products are distributed through original equipment manufacturer (OEM)
  agreements. The Company's products are installed and serviced in most major
  markets by the Company's personnel. Installation and service in some
  countries are provided by authorized representatives. Customers may
  purchase service contracts from the Company to cover equipment no longer
  under warranty, and service work also is provided on a time, materials, and
  expense basis. Training courses on both the operation and maintenance of
  the Company's products are conducted for customers and authorized
  representatives who service the products.

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

       The Company maintains active programs for the development of new
  products using both new and existing technologies and for enhancing
  existing products by improving their price-performance ratio. The
  development of new applications for analytical instrument products is an
  especially important element of the growth strategy for these products.
  Although the Company's products are subject to obsolescence due to
  technological developments, sudden obsolescence is not characteristic of
  the Company's business.

       Research and development expenses for the Company were $42,924,000,
  $34,510,000, and $26,138,000 in 1994, 1993, and 1992, respectively.
                                       7PAGE
<PAGE>
       (iii)  Raw Materials

       The Company manufactures many of the parts and subsystems used in its
  products, including optical components and proprietary circuitry. Other
  components, including packaging materials, integrated circuits,
  microprocessors, and computers, are manufactured by others. The raw
  materials, components, and supplies purchased by the Company are either
  available from a number of different suppliers or from alternative sources
  that could be developed without a material adverse effect upon the
  Company's business.

       (iv)  Patents, Licenses, and Trademarks

       The Company's policy is to protect its intellectual property rights,
  including applying for and obtaining patents when appropriate. The Company
  also enters into licensing agreements with other companies in which it
  grants or receives rights to specific patents and technical know-how.
  Patent protection is believed to provide the Company with competitive
  advantages with respect to certain instruments such as its mass
  spectrometers with ion traps. The Company also considers technical
  know-how, trade secrets, and trademarks to be important to its business.

       (v)  Seasonal Influences

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

       (vi)  Working Capital Requirements

       There are no special inventory requirements or credit terms extended
  to customers that would have a material adverse effect on the Company's
  working capital requirements.

       (vii)  Dependency on a Single Customer

       The Company's Instrument Segment is not dependent upon a single
  customer, or a few customers. The Company's former Services segment, the
  business of which is now conducted by the Thermo Terra Tech joint venture,
  derived approximately 30%, 31%, and 30% of its revenues in the three-month
  period ended April 2, 1994 and in 1993 and 1992, respectively, from
  contracts or subcontracts with the federal government. No single customer
  accounted for more than 10% of the Company's revenues in any of the past
  three years.

       (viii)  Backlog

       The backlog of firm orders for the Instruments segment as of December
  31, 1994 and January 1, 1994 was $139,596,000 and $115,620,000,
  respectively. The backlog of firm orders for the Company's former Services
  segment as of January 1, 1994, was $26,196,000.  The Company anticipates
  that substantially all of the backlog at December 31, 1994, will be shipped
  or completed within the current fiscal year.

       (ix)  Government Contracts

       Not applicable.


                                       8PAGE
<PAGE>
       (x)  Competition

       The Company generally competes on the basis of technical advances that
  result in new products and improved price-performance ratios, reputation
  among customers as a quality leader for products and services, and active
  research and application-development programs. To a lesser extent, the
  Company competes on the basis of price.

       The Company believes it is among the principal manufacturers
  specializing in analytical instrumentation, although it faces significant
  competition from other companies, many of which are larger than the
  Company, and technologies in most of its product lines and its relative
  position in certain markets cannot be determined due to insufficient data.
  The Company believes it is a leading supplier of mass spectrometers, FT-IR
  spectrometers, FT-IR and FT-Raman microscopes, and optical plasma-emission
  spectrometers and a major supplier of atomic absorption spectrometers. In
  liquid chromatography, the Company believes its competitors include several
  larger companies and numerous specialty manufacturers. In its remaining
  analytical instrument product lines, the Company believes its competitors
  are mainly smaller, specialized firms.

       The Company is a leading manufacturer of ambient air monitoring
  instruments and a major manufacturer of source monitoring and worker-safety
  monitoring instruments. Some engineering companies compete for large
  ambient air monitoring installations, but they do not manufacture the
  individual instruments that form a major part of the system, therefore,
  they will often buy these from the Company on an OEM basis.

       The Company has a relatively small presence within the large and
  varied process control marketplace, which is extremely fragmented and
  comprises several large companies and numerous smaller companies.

       (xii)  Environmental Protection Regulations

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

       (xiii)  Number of Employees

       As of December 31, 1994, the Company employed 3,966 people.

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

  Barry S. Howe          39   Vice President (1994)
  Paul F. Kelleher       52   Chief Accounting Officer (1986)

  * John N. Hatsopoulos and George N. Hatsopoulos, a director of the Company,
  are brothers.

       Each executive officer serves until his successor is chosen or
  appointed by the Board of Directors and qualified or until earlier
  resignation, death, or removal. All executive officers, except Mr. Chapman,
  have held comparable positions for at least five years either with the
  Company or with its parent company, Thermo Electron. Mr. Chapman has held
  management positions at the Company's Finnigan Corporation (Finnigan)
  subsidiary since 1989, first as marketing manager and, beginning in 1992,
  as president. Messrs. Helm, Lewis, Chapman, and Howe are full-time
  employees of the Company. Messrs. Smith, Hatsopoulos, and Kelleher are
  full-time employees of Thermo Electron, but devote such time to the affairs
  of the Company as the Company's needs reasonably require.


  Item 2.  Properties

       The Company owns approximately 1,203,000 square feet of office,
  engineering, laboratory, and production space, principally in California,
  Colorado, Florida, New Mexico, Texas, Wisconsin, Germany, and England, and
  leases approximately 957,000 square feet of office, engineering,
  laboratory, and production space under leases expiring from 1995 to 2017,
  principally in California, Massachusetts, Connecticut, Texas, Wisconsin,
  Japan, and Germany. As of December 31, 1994, the Company has a $10,855,000
  mortgage loan that is secured by 200,000 square feet of property in
  California with a net book value of $16,564,000. The Company believes that
  its facilities are in good condition and are suitable and adequate for its
  present operations and that suitable space is readily available if any of
  such leases are not extended.


  Item 3.  Legal Proceedings

       The Company has been notified that the Environmental Protection Agency
  has determined that a release or a substantial threat of a release of a
  hazardous substance, as defined in the Comprehensive Environmental Response
  Compensation and Liability Act of 1980 (CERCLA or the Superfund law),
  occurred at two sites to which chemical or other wastes generated by the
  manufacturing operations of subsidiaries of the Company were sent. The
  notifications allege that these subsidiaries may be potentially responsible
  parties with respect to the remedial actions needed to control or clean up
  any such releases. Under CERCLA, responsible parties can include current
  and previous owners of the site, generators of hazardous substances
                                      10PAGE
<PAGE>
  disposed of at the site, and transporters of hazardous substances to the
  site. Each responsible party can be jointly and severally liable, without
  regard to fault or negligence, for all costs associated with the
  remediation of the site. In each instance the Company believes that its
  subsidiary is only one of several companies which received such
  notification and who may likewise be held liable for any such remedial
  costs. The Company also is involved with one site under California law
  where the Company may be required to participate in remediation.

       The Company evaluates its potential liability as a responsible party
  for these environmental matters on an ongoing basis based upon factors such
  as the estimated remediation costs, the nature and duration of the
  Company's involvement with the site, the financial strength of other
  potentially responsible parties, and the availability of indemnification
  from previous owners of acquired businesses. Estimated liabilities are
  accrued in accordance with Statement of Financial Accounting Standards No.
  5, "Accounting for Contingencies." To date, the Company has not incurred
  any significant liability with respect to any of these sites and the
  Company anticipates that future liabilities related to sites with which the
  Company is currently involved will not have a materially adverse effect on
  the Company's business, results of operations or financial condition.

       On September 27, 1993, Analytica of Branford, Inc. (Analytica) filed a
  complaint against the Company's Finnigan subsidiary in U.S. District Court
  for the District of Connecticut. The complaint alleges that Finnigan has
  used apparatus, and has manufactured and sold products which aid and
  instruct end-purchasers to use the apparatus, in a manner so as to infringe
  a U.S. patent entitled "Method of Producing Multiply Charged Ions and For
  Determining Molecular Weights of Molecules By Use of the Multiply Charged
  Ions of Molecules", and asks for injunctive relief, profits, unspecified
  damages, and attorney's fees. The Company believes that the Finnigan
  products and applications which Analytica seeks to challenge may include
  mass spectrometers equipped with electrospray ionization sources which are
  used for multiple charged ion analysis of high molecular weight compounds.
  Finnigan has filed its answer denying infringement and also has
  counterclaimed for a declaration that the Analytica patent be held invalid
  and not infringed. Discussions between the parties, including settlement
  discussions, are continuing. No trial date has been set.

  To the Shareholders and Board of Directors of
  Thermo Instrument Systems Inc.:


       We have audited, in accordance with generally accepted auditing
  standards, the consolidated financial statements included in Thermo
  Instrument Systems Inc.'s Annual Report to Shareholders incorporated by
  reference in this Form 10-K, and have issued our report thereon dated
  February 10, 1995 (except with respect to the matters discussed in Note 14
  as to which the date is March 1, 1995). 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 14 is the responsibility of the
  Company's management and is presented for purposes of complying with the
  Securities and Exchange Commission's rules and is not part of the basic
  consolidated financial statements. This schedule has been subjected to the
  auditing procedures applied in the audits of the basic consolidated
  financial statements and, in our opinion, fairly states, in all material
  respects, the financial data required to be set forth therein in relation
  to the basic consolidated financial statements taken as a whole.

             (c)  all intercompany receivables, notes or loans with respect to
        the Business between (i) the Seller and its subsidiaries and
        affiliates which are not constituents of the Business and (ii) the

        customarily paid or provided by a seller, as shall be required in
        order to effectively vest, subject only to any required recordation or
        similar filing, in the Buyer all of the Share Sellers' and Asset
        Sellers' right, title and interest in and to the Assets or the Shares,
        as the case may be, provided that (i) where the Buyer is satisfied
                                        3PAGE
<PAGE>
        that title to any of the Assets located in England can effectively
        pass by way of physical delivery without the use of any document of
        transfer, the Seller will deliver or cause to be delivered such Assets
        to the Buyer at Closing, such delivery to take place by means of the
        relevant Assets being retained at the places at which they are

        where title to such Assets can pass only by way of document of

        books of account or ledgers and documentation in support thereof, and
        all other information appearing in writing and relating primarily to
        the Business and which is in any Share Seller's or Asset Seller's
        possession and the minute books and share registers of the Companies
        (it being understood that, subject to the provisions of Section 7.12,
        the Asset Sellers and the Share Sellers shall be entitled to retain
        copies of any of the foregoing, but only to the extent the retention
        of such copies is reasonably necessary for the Asset Sellers and the
        Share Sellers to comply with applicable tax, securities, accounting or
        other laws, rules or regulations and their obligations hereunder).

        2.7  Further Assurances.  At the Closing and at any time or from time
   to time thereafter, at the request of the Buyer and without further
   consideration, the Seller shall, and shall cause each Share Seller and

   determine is necessary to put the Buyer  in actual possession and operating
   control of the Business and (ii) execute, acknowledge and deliver such  
   further instruments of conveyance, sale, transfer and assignment  as the
   Buyer may reasonably request, and take such other action  as the Buyer may
   reasonably request, in order to convey, sell, transfer and assign to the
   Buyer the Assets and the  Shares, to evidence the Buyer's rights to, title
   in and ownership  of the Assets and the Shares and to consummate the
   transactions contemplated hereby.  At the Closing and at any time and from
   time to time after the Closing, at the request of the Seller and without
   further consideration, the Buyer shall, and shall cause each of its
   Subsidiaries to, take such action and execute, acknowledge and deliver such

             (a)  The Seller shall use all reasonable efforts, and the Buyer
        shall cooperate reasonably with the Seller, (i) to  promptly obtain
        the consents and waivers necessary to convey  or cause to be conveyed
        to the Buyer all of the Restricted Assets, and (ii) as of and subject
        to the  occurrence of the Closing, to promptly convey or cause to be  
        conveyed to the Buyer the Restricted Assets for  which the Seller has
        received the necessary consents and  waivers; provided, however, that
        the Seller shall not, and  shall cause the Asset Sellers not to, amend
        or change any  Restricted Asset without the prior written  consent of
                                        4PAGE
<PAGE>
        the Buyer unless the Seller reasonably deems it  necessary to preserve
        the value of the Restricted Asset.   The Seller shall, and shall cause
        the Asset Sellers to,  cooperate with the Buyer in making applications
        and filings  or taking any other action necessary for the Buyer to
        obtain  such franchises, licenses, permits or other instruments or  
        agreements, if any, as are substantially equivalent to any Restricted
        Assets that are not assignable to Buyer as a matter of law.  In no
        event shall the  Buyer's cooperation hereunder require the Buyer to
        make any  payments or incur any out-of-pocket expenses, except that
        the Buyer shall reimburse the Seller on an equitable basis  for any
        consideration paid, with the prior approval of the  Buyer, to any
        person from whom a consent or waiver is  requested.

             (b)  To the extent that the consents and waivers necessary to
        assign, transfer, sublease or sublicense any of the Restricted Assets
        are not obtained, the Seller  shall, commencing on the Closing Date
        and continuing for the duration of each such Restricted Asset, use
        reasonable  efforts to (i) provide to the Buyer the benefits of any  
        such Restricted Asset not assigned, transferred or  subleased due to
        the Seller's failure or inability to obtain  such consent or waiver,
        (ii) cooperate with the Buyer to  reach a reasonable and lawful
        arrangement designed to  provide such benefits to the Buyer during
        such period and  (iii) enforce at the request of the Buyer, or allow
        the Buyer  to enforce (and, solely for such purpose, the Seller hereby
        constitutes and appoints the Buyer as its true and lawful  
        attorney-in-fact until revoked in a writing delivered by the  Seller
        to the Buyer), any rights of the Seller under any such Restricted
        Asset against the issuer thereof or  the other party or parties
        thereto (including the right to  elect to terminate such of the
        foregoing in accordance with  the terms thereof upon the request of
        the Buyer); provided, however, that the reasonable costs and expenses
        of the  Seller (including reasonable professional fees and expenses)
        incurred at the Buyer's request with respect to any  of the actions
        contemplated under (iii) above shall be  promptly paid or reimbursed
        by the Buyer to the Seller.  At  the end of each such period, the
        Seller shall have no further  duties or obligations under this
        Section 2.8 with respect to such Restricted Asset and the failure or  
        inability to obtain any necessary consent or waiver with  respect
        thereto shall not be a 

        breach of this Agreement so  long as the Seller has carried out its
        obligations under  this Section 2.8.

             (c)  To the extent that the Buyer is provided the benefits of any
        Restricted Asset pursuant to clause (b) of this Section 2.8, the Buyer
        shall perform for the benefit of the issuer thereof, or the other
        party or parties thereto, the obligations of any Asset Seller
        thereunder or in connection therewith, but only to the extent that (i)
        such action by the Buyer would not result in any default thereunder or
        in connection therewith and (ii) such obligation would have been an
        Assumed Liability but for the non-assignability or non-transferability
        thereof; provided, however, that if the Buyer shall fail to perform to
                                        5PAGE
<PAGE>
        the extent required herein, the Seller shall thereafter cease to be
        obligated under this Section 2.8 to provide the Buyer with any
        benefits in respect of the Restricted Asset which is the subject of
        such failure to perform unless and until such situation is remedied
        or, at the sole option of the Seller, the Buyer shall promptly pay or
        reimburse the Seller to remedy such failure to perform during such
        period of failure of performance. 

        2.9  UK Property.  In addition to the terms and conditions hereof, the
   terms and conditions set forth on Exhibit B shall apply to the sale of the
   UK Property.

        2.10 Intercompany Accounts.  Prior to or on the  Closing Date, the
   Seller shall, and shall cause its Subsidiaries to, eliminate, to the extent
   legally possible, all intercompany accounts related to the Business between
    (a) the Seller and its subsidiaries and affiliates which are not  
   constituents of the Business and (b) the Asset Sellers or the Companies,

        3.3  Documents of Assumption.  At the Closing, the  assumption of the
   Assumed Liabilities by the Buyer shall be  evidenced by the execution and
                                        7PAGE
<PAGE>
   delivery to the Asset Sellers of  instruments of assumption and such other
   instruments as the Seller may  reasonably request in order to effect the
   assumption by the Buyer  of the Assumed Liabilities.  After the Closing,
   the Buyer shall, at the written request of Seller, use reasonable efforts
   to arrange over time for the substitution of the Buyer for the Seller and
   its Subsidiaries and Affiliates that are not constituents of the Business
   on the agreements, obligations and liabilities in respect of the Business
   which are obligations of the Seller and its Subsidiaries and Affiliates
   that are not constituents of the Business, including, without limitation,
   those agreements, obligations and liabilities listed on Schedule 5.26.

        3.4  Risk of Loss.  The risk of loss of any of the Assets or the
   Company Assets shall be the responsibility of the Buyer as of the Closing
   Date.  All casualty or other losses of Assets or Company Assets or to the
   Business occurring after such time shall be the responsibility of the
   Buyer, whether or not the Buyer has purchased or obtained any insurance
   coverage.

   4.   PURCHASE PRICE MATTERS.

        4.1  Post-Closing Adjustment.  The Purchase Price set forth in Section
   2.1 shall be subject to adjustment after the Closing Date as follows:

        (a)  Within 60 days after the Closing Date, the Seller shall prepare
   and deliver to the Buyer a consolidated balance sheet of the Business
   reflecting the assets and liabilities of the Business as of the Closing
   Date without giving effect to the transactions contemplated by this
   Agreement, which shall consist only of the Assets, the Company Assets, the
   Assumed Liabilities and the Company Liabilities (the "Draft Closing Balance
   Sheet").  The Seller shall prepare the Draft Closing Balance Sheet in
   accordance with English generally accepted accounting principles ("GAAP")
   and the Accounting Principles and in such detail as the Buyer shall
   reasonably request.  The Draft Closing Balance Sheet shall include
   appropriate accruals for (x) liabilities of the Business incurred prior to
   the Closing Date but for which invoices have not been received as of the
   Closing Date and (y) prepayments in respect of the Business.

        (b)  The Buyer shall deliver to the Seller within 60 days after
   receiving the Draft Closing Balance Sheet a detailed statement describing
   its objections (if any) thereto. Failure of the Buyer so to object to the
   Draft Closing Balance Sheet shall constitute acceptance thereof, whereupon
   the Draft Closing Balance Sheet shall be deemed to be the "Closing Balance
   Sheet".  The Buyer and the Seller shall use reasonable efforts to resolve
   any such objections, but if they do not reach a final resolution within 30
   days after the Seller has received the statement of objections, the Buyer
   and the Seller shall select an accounting firm mutually acceptable to them
   (the "Neutral Auditors") to resolve any remaining objections.  If the Buyer
   and the Seller are unable to agree on the choice of Neutral Auditors, they
   shall select as Neutral Auditors an internationally-recognized accounting
   firm by lot (after excluding their respective regular independent
   accounting firms).  The Draft Closing Balance Sheet shall be adjusted by
   the Neutral Auditors only to conform to GAAP and the Accounting Principles
                                        8PAGE
<PAGE>
   and, as so adjusted, shall be the Closing Balance Sheet.  Such
   determination by the Neutral Auditors shall be conclusive and binding upon
   the Buyer and the Seller, absent fraud or manifest error.

        (c)  During the preparation of the Draft Closing Balance Sheet by the
   Seller and the period of any dispute referred to above, the Buyer shall
   promptly disclose to the Seller, the Seller's independent accountants and,
   if applicable, the Neutral Auditors all relevant facts and information,
   give them full access to books, records, facilities and employees of the
   Business and cooperate fully with the Seller, the Seller's accountants and,
   if applicable, the Neutral Auditors in order to prepare the Draft Closing
   Balance Sheet or the Closing Balance Sheet, as the case may be;  provided,
   however, that any such access shall be allowed only in such manner as not
   to interfere unreasonably with the operation of the Business.

        (d)  The Buyer and the Seller shall share equally the fees and
   expenses of the Neutral Auditors. 

        (e)  If the Net Book Value (as defined below) as shown on the Closing
   Balance Sheet is less than the Interim Net Book Value, the Seller shall pay
   to the Buyer, by wire transfer or other delivery of immediately available
   funds, within three business days after the date on which the Closing
   Balance Sheet is finally determined pursuant to this Section 4.1, an amount
   equal to such deficiency (plus interest thereon from the Closing Date at
   the interest rate equal to 1% above LIBOR as in effect from time to time).
   "Net Book Value" shall mean the excess of the combined tangible Assets and
   Company Assets (and for the avoidance of doubt shall include accounts
   receivable, cash, bank balances and similar assets) over the combined
   Assumed Liabilities and Company Liabilities.

        (f)  If the Net Book Value as shown on the Closing Balance Sheet
   exceeds the Interim Net Book Value, the Buyer shall pay to the Seller, by
   wire transfer or other delivery of immediately available funds, within
   three business days after the date on which the Closing Balance Sheet is
   finally determined pursuant to this Section 4.1, an amount equal to such
   excess (plus interest thereon from the Closing Date at the interest rate
   equal to 1% above LIBOR as in effect from time to time). 

        4.2  Allocation of Purchase Price.  The parties shall use reasonable
   efforts to agree prior to the Closing on an allocation of the Purchase
   Price (and all other capitalizable costs).

        4.3  Transaction Taxes.  Any and all federal, state, county,  local or
   foreign sales, use, value added, excise, stamp, transfer  and other taxes
   not in the nature of income taxes, fees and  duties (including any
   interest, additions to tax and penalties  with respect thereto) and any and
   all transfer, recording or  similar fees and charges (collectively,
   "Transaction Taxes") imposed in connection with the  consummation of the
   transactions contemplated hereunder shall be borne equally by the Buyer and
   the Seller, provided, however, that this Section 4.3 shall not apply to any
   VAT, which shall be borne by the Buyer, subject to Section 7.9(h).

        Seller, has accurately prepared and duly and timely filed all material
        Tax Returns that it was required to file.  All such material Tax

        any Asset Seller, (whether or not shown on any Tax Return) have been
        paid when due, other than those for which adequate reserves have been
        established on the Balance Sheet.  No Company is currently the
        beneficiary of any extension of time within which to file any material
        Tax Return.  No written claim or inquiry with respect to any material
        amount of Taxes has ever been made by an authority in a jurisdiction
        where any Company or, with respect to the Business, any Asset Seller,
        did not file Tax Returns that such Company or, with respect to the

        jurisdiction.  There are no liens or other security interests (other
        than Permitted Encumbrances) on any of the Assets or the Company
        Assets that arose in connection with any failure (or alleged failure)
        to pay any Tax.

        portions thereof ending on or prior to the Balance Sheet Date,
        including Taxes that may become payable by any such Company in future
        periods in respect of any transactions or sales occurring on or prior
        to the Balance Sheet Date, that have not yet been paid have, in the
        aggregate, been adequately reflected as a liability on the Balance
        Sheet in accordance with GAAP consistently applied.

             (c)  Without limiting the generality of the foregoing, each
        Company has withheld or collected and duly paid all material Taxes
        required to have been withheld or collected and paid in connection
        with amounts paid or owing to or from any employee, independent
        contractor, creditor, stockholder, or other third party.  

             (d)  To the Seller's Knowledge, there is no dispute or claim

        relevant portions thereof) and statements of deficiencies assessed,
        proposed in writing to be assessed against, or agreed to with respect
        thereto by any such Company or, with respect to the Business, such
        Asset Seller, since January 1, 1988.

             (e)  None of the Companies has made a currently effective waiver
        of any statute of limitations in respect of material Taxes or agreed
        to any currently effective extension of time with respect to a
        material Tax assessment or deficiency.  

             (f)  None of the Companies has filed a consent under Code Section
        341(f) concerning collapsible corporations.  None of the Companies has
        made any payments, is obligated to make any payments, or is a party to

       trademarks, registered tradenames and registered service marks and
       applications therefor; and (iii) registered licenses relating to any of
       the  foregoing.  Schedule 5.15 identifies the owner of each item
       listed thereon and, in the case of registrations and  applications, the

             (b)  The Asset Sellers and the Companies own or have the right to
       use all Proprietary Rights used in the operation of the Business as
       heretofore conducted or necessary for the operation of the Business as

       be owned or available for use by the Buyer or  the Companies on
       substantively identical terms and conditions  immediately following the
       Closing, except as otherwise indicated on Schedule 5.15.  Each of the

       protect the proprietary nature of the  Intellectual Property and to
       maintain in confidence the trade  secrets and confidential information
       that it owns or uses in, and that are material to, the Business.  No
       other person or  entity has any rights to any of the Intellectual
       Property  owned or used by the Asset Sellers or the Companies that are

       identified on Schedule 5.15 as licensed to the  Companies or, in  the
       conduct of the Business, to the Asset Sellers,  is owned by the
       respective owners identified on  Schedule 5.15.   Except as set forth
       on Schedule 5.15, to the Seller's Knowledge, no person or entity is
       infringing,  violating or misappropriating any of the Intellectual  
       Property.  Except as set forth on  Schedule 5.15, no Asset Seller or
       Company has agreed, except in the Ordinary  Course of Business in
       conjunction with product sales,  to indemnify any person or entity for
       or against any  infringement, misappropriation or other conflict with
       any Intellectual Property.

             (c)  Except as set forth on Schedule 5.15, to the Seller's
       Knowledge, none of the activities or business presently conducted by
       the Business infringes or violates, or constitutes a misappropriation
       of,  any Proprietary Rights of any other person or entity (including,
       without limitation, the Seller or any Subsidiary or Affiliate of the
       Seller).  Except as set forth on Schedule 5.15, no Company, or, in the
       conduct of the Business, Asset Seller, has received since January 1,
       1992, any complaint, claim or notice in writing alleging any such
       infringement, violation or  misappropriation, which complaint, claim or
       notice has not been resolved to the mutual satisfaction of the parties
       involved in a manner which involves no future obligations of the
       Seller.  

             (d)  Except as set forth on Schedule 5.15A, with respect to each
        item of Intellectual Property owned by a third party and used by a

                 (i)   the license, sublicense or other agreement covering
             such item is legal, valid, binding, enforceable and in full force
             and effect with respect  to the Asset Seller or Company which is
             a party thereto;

                (ii)   such license, sublicense or other agreement to which an
              Asset Seller is a party is assignable by the Asset  Seller to
             the Buyer without the consent or approval of or any payment to
             any party and the consummation of the transactions contemplated
             herein  will not conflict with, result in a violation or breach  
             of or constitute a default under (or would result in a  
             violation, breach or default with the giving of notice  or the
             passage of time or both) any such license,  sublicense or other
             agreement which violation, breach or default (together with all
             other such violations, breaches or defaults) would have a
             Material Adverse Effect;

               (iii)   neither any Asset Seller or Company nor, to the
             Seller's Knowledge, any other party is in  breach or default
             under any such license, sublicense or  other agreement, and no
             event has occurred which, with  notice and/or lapse of time,
             would constitute such a  breach or default or permit a
             termination, modification  or acceleration thereunder; 

                (iv)   to the Seller's Knowledge, the underlying item of
             Intellectual Property is not subject to any  outstanding
             judgment, order, decree, stipulation or  injunction; and 

                 (v)   no Asset Seller or Company has agreed, except in the
             Ordinary Course of Business in conjunction with product sales,  
             to indemnify any person or entity for or against any  
             interference, infringement, misappropriation or other conflict
             with respect to such item.

       by or on  behalf of the Asset Sellers, the Share Sellers or  the
       Companies applicable to employees of the Business  employed in the U.S.
       (the "Plans").  The Fisons Scientific Equipment Savings Incentive Plan
       including the related trust (the "Savings Plan") has received a
       favorable determination letter from the IRS and, to the Seller's
       Knowledge, no event has occurred and no condition exists which could
       reasonably be expected to result in the revocation of any such
       determination.  Each of  the Plans has been administered in compliance
       with its terms and the requirements of all  applicable Laws and
       Regulations, including without limitation  ERISA and the Code, and all
       required contributions to each  Plan have been made, in each case,
       except where the failure to do so would not have a Material Adverse

       termination proceedings and no actions, suits or claims  (other than
       claims for benefits in the Ordinary Course of Business) pending or, to
       the Seller's  Knowledge, threatened against the Savings Plan (or any 
                                       26PAGE

             (c)  No Company has ever maintained an employee benefit plan
        subject to Section 412 of the Code or Title IV of ERISA.

             (d)  Neither any Asset Seller, any Share Seller, any Company nor
       any ERISA Affiliate  contributes to, has within the past five years had
       an obligation to contribute to, or is subject to a liability to, a  
       "multi-employer plan" as defined in Section 4001(a)(3) of  ERISA.  

             (e)  Except as set forth in Schedule 5.24, there are no unfunded
       obligations under any Plan providing benefits after  termination of
       employment to any employee or former employee  of the Business (or to
       any beneficiary of any such employee  or former employee), including
       but not limited to retiree  health coverage and deferred compensation,
       but excluding  continuation of health coverage required to be continued
        under Section 4980B of the Code and insurance conversion  privileges
       under state law.  

             (f)  Except as set forth in Schedule 5.24, no act or omission has
       occurred and no condition exists with respect to  any employee benefit
       plan maintained by any Asset  Seller, any Share Seller, any Company or
       any ERISA  Affiliate that would subject any Company or the  Assets to
       any fine, penalty, tax or liability of any  kind imposed under ERISA or
       the Code, in each case, that would have a Material Adverse Effect.  

             (g)  Schedules 5.24 and 5.25 disclose each: (i)  agreement, plan
       or arrangement under which any person may receive payments from a
       Company or from any Share Seller or Asset Seller with respect to any
       employee of the Business, that may be  subject to the tax imposed by
       Section 4999 of the Code or  included in the determination of such
       person's "parachute  payment" under Section 280G of the Code; and
       (ii) agreement or  plan binding any Company or, with respect to any
       employee of the Business, any Share Seller or Asset Seller, including

       by  this Agreement or the value of any of the benefits of which  will

       this Agreement.

       5.25  Foreign Employee Benefit Plans.  Schedule 5.25 lists  (i) each
   retirement plan that is not statutorily required (disregarding for this
   purpose the United Kingdom Statutory requirement for any contracted-out
   schemes to provide guaranteed minimum pensions under the United Kingdom
   Pension Schemes Act 1993) that is maintained or contributed to by or on
   behalf of any Asset Seller, Share Seller or Company applicable to  
   employees of the Business located outside of the U.S. (a "Foreign  
   Retirement Plan") and (ii) each welfare benefit plan that is not required
                                       27PAGE

   contributed to by or on behalf of any Asset Seller, Share Seller or Company
   applicable to employees of the Business located  outside of the U.S. and
   which, in the case of clause (ii),  obligates or may reasonably be expected
   to obligate the Business  to provide a value of more than 100,000 English
   pounds sterling annually (a "Foreign Welfare Plan").   Except as set forth
   in Schedule 5.25, each such Foreign Retirement  Plan and Foreign Welfare
   Plan (collectively, the "Foreign Plans")  is fully funded, has been
   administered, in all material respects, in compliance  with its terms and
   the requirements of all applicable Laws and  Regulations (including,
   without limitation, Article 119 of the Treaty of Rome), and all required
   contributions to each Foreign Plan  have been made.  The books and records
   of the Companies and, with respect to the Business, the Asset Sellers,
   accurately reflect the obligations and liabilities of the Companies and the
   Asset Sellers under the Foreign Plans.  The Seller has heretofore delivered
   to the Buyer  true and complete copies of all of the written Foreign Plans
   and written summaries of the oral Foreign Plans and, where  applicable,
   related trusts and contracts, including all amendments.  There are  no
   inquiries or investigations by any foreign Governmental Body,  no
   termination proceedings and no actions, suits or claims (other  than claims
   for benefits) pending or, to the Seller's Knowledge,  threatened against
   any Foreign Plan (or any Company, Share Seller or Asset Seller with respect
   thereto) or  the assets thereof.  Except as set forth in Schedule 5.25,
   there  are no unfunded obligations under any Foreign Plan providing  
   benefits after termination of employment to any employee or  former
   employee of the Business (or to any beneficiary of any  such employee or
   former employee), including but not limited to  retiree health coverage and
   deferred compensation, but excluding  insurance conversion privileges under
   applicable foreign law.  No  Foreign Plan, plan documentation or agreement,
   summary plan  description or other written communication distributed
   generally  to employees of the Business by its terms prohibits the
   amendment  or termination of any such Foreign Plan.  All reports, forms and
    other documents required to be filed or advisable to be filed  with any
   governmental entity with respect to each Foreign Plan  have been timely
   filed and are complete and accurate in all material respects.  

       5.26  Indebtedness and Guaranties.  Schedule 5.26 sets forth a  true
   and complete list (indicating the obligor, the beneficiary, the amount and
   the date of maturity or expiration), including the names of the parties  
   thereto, of all debt instruments, loan agreements,  indentures, guaranties
   or other written obligations which relate  to (i) indebtedness for borrowed
   money or (ii) money loaned to others, provided that the Seller shall not be
   required to list  any such obligations which (a) include less than 100,000
   English pounds sterling or (b) are general corporate obligations of  the
   Seller, which are not secured by any of the Assets, the Company Assets or
   the Shares and which do not constitute an Assumed Liability or Company
   Liability.  All of the aforesaid items were  entered into in the Ordinary
   Course of Business, are valid and  binding, in full force and effect and
   are enforceable in  accordance with their respective terms; there exists no
    breach or default, or any event which with notice or lapse of  time or
   both, would constitute a breach or default by any party  thereto; and there
   are no prepayment penalties associated therewith.

       each Asset Seller and each Company is in compliance in all material
       respects with all Environmental  Laws applicable to the Business.   
       Except as set forth in  Schedule 5.28, there is no pending or, to the

       Response Act of 1980, as amended ("CERCLA"). 

             (b)  Except as set forth in Schedule 5.28, to the Seller's
       Knowledge, there has been no release of any Materials of Environmental
       Concern in amounts above reportable quantities under applicable
       Environmental Laws into the environment at any parcel of  real property

       formerly owned, operated or controlled by any Company during the period
       of its ownership, operation or control, that, in each case, would have

       hazardous substances (as such term is defined  under CERCLA), solid
       wastes and hazardous wastes (as such  terms are defined under the

       to premises (i) currently  owned or operated by any Share Seller or any
        Asset Seller in the conduct of the Business or (ii) currently owned  
       or operated by any Company, in each of the foregoing  cases whether

       Company or a third  party, and whether done at the initiative of the
       Seller, any  Share Seller, any Asset Seller or any Company or  directed
       by a Governmental Body or other third party.   Copies of each such
       report, or the  results of each such report, investigation or audit in
       the possession of any Asset Seller, Share Seller or Company, have been
       provided or made available to the Buyer (except that only summaries of
       the  results of statistical information resulting from physical  
       monitoring or testing have been provided to the Buyer).  

             (d)  The Seller has provided or made available to the Buyer a
       list of, to the Seller's Knowledge, all of the solid and hazardous
       waste transporters and treatment, storage  and disposal facilities that
       have been utilized by any Share Seller or any Asset Seller in the
       conduct of the Business since January 1, 1980 or by any Company at any
       time.   Neither any Share Seller, any  Asset Seller nor any Company has
       received written  notice of any liability under any Environmental Law
       of any such  transporter or facility which would have a Material
       Adverse Effect.

             (e)  Without limiting the generality of the foregoing paragraphs

   Companies as heretofore operated or for the conduct of the Business as
   heretofore conducted, except for any such permits the failure to hold which
                                       30PAGE

   is  assignable by the Asset Seller to the Buyer without the consent  or
   approval of or any payment to any party, all such Material Permits  
   (whether held by an Asset Seller or Company) will  continue to be in full
   force and effect immediately following the  Closing in accordance in all
   substantive respects with the terms thereof as in effect  immediately prior
   to the Closing, and the consummation of the  transactions contemplated
   herein will not conflict with, result in  a violation or breach of or
   constitute a default under (or would  result in a violation, breach or
   default with the giving of  notice or the passage of time or both) any such

   respects.  The stock certificate books, stock ledgers and/or share
   registers of each Company are complete and correct in all material
   respects.  

       5.32  Customers and Suppliers.  No unfilled customer orders  or
   commitments obligating any Division, Business Seller or Company to process,
   manufacture or deliver products or  perform services, which orders or
   commitments are material, individually or in the aggregate, to the Business
   will result in a material loss to the Business upon completion of
   performance.  To the Sellers' Knowledge, no purchase orders or commitments
   of any  Division, Business Seller or Company, which  orders or commitments
   are material, individually or in the  aggregate, to the Business are
   materially in excess of  normal requirements of the Business, nor are

   the products or services to be provided  thereunder.  No material supplier
   of the Business has indicated within the  past year that it will stop, or

   more  than 1% of the combined revenues of the Business during the 1994
   fiscal year and (b) each supplier that is  the sole supplier of any
   significant product or component to the Business.  Except  as set forth on

   or services with respect to which practical  alternative sources of supply,
   or comparable products, are not  available on comparable terms and
   conditions.

   is, or since December 31, 1992 has been, suspended or debarred from  
   bidding on contracts or subcontracts with any Governmental Body;  no such
   suspension or debarment has been initiated or, to the  Seller's Knowledge,
   threatened in writing; and the consummation of the  transactions
   contemplated by this Agreement will not result in  any such suspension or
   debarment (assuming that no such  suspension or debarment will result
   solely from the identity of  the Buyer).  Except as set forth on
   Schedule 5.33, no Division, Business Seller or Company has, since December
   31, 1992, been audited or investigated or is now being audited or, to the
   Seller's  Knowledge, has been threatened in writing with an investigation

   Body, any similar  agencies or instrumentalities of any foreign
   Governmental Body,  or any prime contractor with a Governmental Body nor,
   to the  Seller's Knowledge, has any such audit or investigation been  
   threatened in writing.  To the Seller's Knowledge, there is no valid basis
   for (a) the suspension or debarment of any Division,  Business Seller or
   Company from bidding on contracts or  subcontracts with any Governmental
   Body or (b) any claim pursuant  to any audit by any Governmental Body in
   connection with any contracts or subcontracts relating to the provision of
   products or services to or for the benefit of a Governmental Body.  Except
   as set forth on Schedule 5.33, no Division, Business Seller or Company has
   any agreements, contracts or commitments which require it to obtain  or
   maintain a security clearance with any Governmental Body.  

       5.34  Recalls.  To the Seller's Knowledge, there is no basis  for the
   recall, withdrawal or suspension of any approval by any  Governmental Body

                                       32PAGE

   basis therefor) for a broker's or finder's fee to be paid by the Buyer or

   contemplated hereby.

   meaning of foreign, federal or state securities laws, if applicable.

             permitted by this Agreement if such action or failure to take

             untrue in any material respect or (b) any of the  conditions to

        are commenced or threatened and may affect  the transactions
        contemplated by this Agreement or (ii) to the Seller's Knowledge, are
        commenced or threatened in writing and may have a Material Adverse
        Effect.

             (c)  During the period from the date of this Agreement to the
        Closing, the Seller shall, and shall cause each Share Seller, Asset

   the Seller shall (and shall cause each Share Seller,  each Asset Seller and
   each Company to) permit  representatives of the Buyer to have full access
   to all premises,  properties, financial, tax and accounting records,
   contracts, other  records and documents and personnel of or pertaining to
   the Business; provided, however, that such access shall be allowed only
   during normal business hours, with reasonable advance notice  and in such
   manner as not to interfere unreasonably with the  normal business
   operations of the Business.  Prior to the  Closing, the Seller shall also
   furnish to the Buyer or its  representatives such information as the Buyer
   may reasonably request in connection with any review, investigation or 
                                       36PAGE

   connection therewith, the Seller shall direct  and authorize its
   independent public accountants to make  available to the Buyer and to the
   independent public accountants  representing the Buyer all working papers
   pertaining to the  examination and audit by such accountants of the
   Business.  Costs  reasonably incurred by the Seller to third parties at the
   Buyer's  request arising from or due to the Buyer's review of the Business

        7.3  Filings and Authorizations.

             (a)  Each of the Seller and the Buyer, as promptly as practicable
        after the date hereof, (i) shall make, or cause to be made, all such
        filings and submissions required under Laws and Regulations applicable
        to it, or to its  Subsidiaries and Affiliates, as may be required for
        it to  consummate the purchase and sale of the Assets and the  Shares
        in accordance with the terms of this Agreement, including, without
        limitation, the filings and submissions listed on Schedules 5.4 and
        6.3 hereof;  (ii) shall use its best efforts to obtain, or cause to be
         obtained, all authorizations, approvals, consents and  waivers from
        all persons and Governmental Bodies necessary  to be obtained by it,
        or its Subsidiaries or Affiliates, in  order for it so to consummate
        such transfer; and (iii) shall  use its best efforts to take or cause
        to be taken all other  actions necessary, proper or advisable in order
        for it to  fulfill its obligations hereunder.   Notwithstanding the  
        foregoing, the Buyer shall not be required to (i) sell or  dispose of
        or hold separately (through a trust or otherwise)  any assets or
        businesses of the Buyer, its Affiliates or the Business, or make any
        other change in any portion of its business or incur any other
        limitation on the Buyer's conduct of its business to obtain such
        authorizations, approvals, consents and waivers, (ii) incur
        out-of-pocket expenses of third parties of more than 500,000 English
        pounds sterling in performing its obligations under this Section
        7.3(a) or (iii) respond to formal requests for additional information
        or documentary material pursuant to 16 C.F.R. 803.20 under the HSR Act
        or other similar Laws or Regulations, provided, however, that the
        Buyer shall, after any such request, use its best efforts to seek to
        limit the scope and amount of information that the relevant
        Governmental Body is seeking to a level acceptable to the Buyer and
        shall provide such limited level of information informally to such
        Governmental Body in lieu of complying with the formal request.  The
        Seller and the Buyer will coordinate and  cooperate with one another
        in exchanging information relating to the foregoing and supplying such
        reasonable assistance as may be  reasonably requested by each in
        connection with the foregoing.  If (w) the Buyer elects not to comply
        with any such formal request under the HSR Act, (x) the conditions to
        Closing specified in Section 8.7 and 9.5 with respect to the HSR Act
        have not been satisfied as of the Termination Date and (y) all other
        conditions to Closing specified in Section 8 and 9 have been
        satisfied, except for any such conditions that would have been
        satisfied but for a breach by the Buyer of this Agreement, then the
                                       37PAGE
<PAGE>
        Buyer shall reimburse the Seller for its out-of-pocket expenses to
        third parties incurred in connection with the transactions
        contemplated hereby up to a maximum of 500,000 English pounds
        sterling.

             (b)  With respect to the filings and actions, if any, necessary
        to comply with  all applicable provisions and requirements of the
        Industrial  Site Recovery Act, N.J.S.A. C.13:1K-6 ("ISRA"), pertaining
         to any Assets located in the State of New Jersey that are subject to
        ISRA requirements, such actions and filings  shall include, but are
        not limited to, submission  of (i) a notice to the New Jersey
        Department of  Environmental Protection and Energy ("NJDEPE")
        regarding the  transfer of ownership and operations of Assets or
        Company Assets located in the State of New Jersey, and  (ii) a
        remediation agreement, including a demonstration that  a remediation
        funding source has been established.  Such  submissions shall be made
        unless the Seller reasonably  demonstrates that an alternative method
        of compliance with  ISRA's requirements will ensure an earlier Closing
        Date.   Regardless of the method of ISRA compliance chosen, the Seller
        shall obtain from the NJDEPE, prior to the Closing,  all consents,
        approvals, authorizations and waivers required  by ISRA covering the
        transactions contemplated by this  Agreement.  Notwithstanding any
        other provision of this  Agreement, the Seller shall retain, at its
        sole cost and  expense, all responsibility for compliance with any and
        all  ISRA obligations required by the NJDEPE for the transfer of  the
        Assets or Company Assets located in the  State of New Jersey from and
        after the Closing, except to the extent that any cost, expense or
        obligation is attributable to acts or omissions of the Buyer
        subsequent to the Closing.

        (c)  Subject to Section 7.3(a), the Buyer and the Seller shall
        cooperate in taking such actions as shall be necessary or desirable to
        satisfy the Buyer that the United Kingdom Secretary of State for Trade
        and Industry will not refer the proposed acquisition of the Shares and
        the Assets by the Buyer hereunder to the United Kingdom Monopolies and
        Mergers Commission.

        7.4  Exclusivity.  Prior to the termination of this Agreement pursuant
   to Section 12 hereof, except as may be required by fiduciary duties of the
   Board of Directors of the Seller under applicable law, the Seller shall not
   and shall cause the Asset Sellers, the Share Sellers, the Companies and the
    Seller's other Affiliates not to, and shall cause each of its and their
   respective officers, directors, employees, representatives and agents not  
   to, directly or indirectly, (a) encourage, solicit, initiate,  engage or
   participate in discussions or negotiations with any  person or entity
   (other than the Buyer) concerning any merger,  consolidation, sale of
   assets, tender offer, recapitalization,  accumulation of shares of stock,
   proxy solicitation or other  business combination involving the Business,
   any Division, any Business Seller or any Company or any  material portion
   thereof or (b) except as may otherwise be required by applicable law or
   Governmental Body, provide any non-public information  concerning the
   Business to any person or entity (other than the  Buyer, the Seller and the
                                       38PAGE
<PAGE>
   Seller's Subsidiaries).  Except as may otherwise by required by applicable
   law or Governmental Body, the Seller shall immediately notify the Buyer of,
   and  shall disclose to the Buyer all details of, any inquiries,  
   discussions or negotiations of the nature described in this  Section 7.4.

        7.5  Bulk Sales.  It may not be practicable to comply or  attempt to
   comply with the procedures of the bulk sales or bulk  transfers acts or
   laws of any or all of the states or other  jurisdictions in which the
   Assets are situated (or of any state  or jurisdiction) which may be
   asserted to be applicable to the  transactions contemplated hereby.  The
   Buyer and the Seller  therefore waive any requirements for compliance with
   any or all  of such laws.

        7.6  Employment of Business Work Force.

             (a)  Prior to the Closing, but effective as of and conditioned on
        the occurrence of the Closing, the Buyer shall make an offer of
        employment  to each employee of the Asset Sellers employed in the
        Business (except the UK Employees employed in that part of the
        Business that is situated in the United Kingdom (the "UK Business"))
        who on the Closing Date is actively at work or absent due to
        short-term disability (as defined in the plan covering the employee),
        parental leave, jury  duty, vacation, military service, or similar
        short-term leave and, upon acceptance by such  employee, enter into an
        at will employer-employee relationship  with such employee.   The
        terms of said offer of the Buyer to each such  employee shall include
        the payment of cash compensation which is substantially equivalent to
        that provided to such employee immediately prior to the Closing Date,
        and benefits, in the aggregate, on a basis substantially consistent
        with the Buyer's normal practices for its existing comparable
        employees; provided, however, that the Buyer shall have complete
        discretion to  change any of the terms or conditions of employment,
        compensation  or benefits at any time after the Closing Date.

             (b)  (i) The Seller and the Buyer anticipate that the United
        Kingdom Transfer of Undertakings (Protection of Employment) Regulation
        1981 (the "Transfer Regulations") will apply to the sale and purchase
        under this Agreement of the UK Business; the Seller and the Buyer
        acknowledge and agree that under the Transfer Regulations, the
        contracts of employment between the Seller and the UK Employees will
        have effect after the Closing Date as if originally made between the
        Buyer and the UK Employees.

             (c)  The Buyer agrees that the service of Continuing Employees
        with the Seller or its Affiliates or predecessors prior to the Closing
        Date shall be taken into account for all relevant purposes under the
        Buyer's employee benefit plans, including credit for eligibility,
        vesting and benefit accrual.  The Seller shall provide the Buyer with
        copies of records reasonably required to establish each such
        employee's service prior to the Closing Date.  The Buyer shall (i)
        allocate to such employees a number of days of vacation equal to the
        number of accrued and deferred vacation days that would be due such
                                       39PAGE
<PAGE>
        employees as of the Closing Date if such employees were voluntarily
        terminating their employment with the Seller as of the Closing Date
        and (ii) pay such employees who terminate their employment with the
        Buyer for their accrued and deferred vacation allocations existing at
        the time of their termination.  The Seller shall provide the Buyer
        with records showing the amount of accrued and deferred vacation due
        and owing to each such employee as of the Closing Date and an accrual
        therefor will be recorded on the Closing Balance Sheet.

             (d)  The parties hereto do not intend to create any third-party
        beneficiary rights respecting any employee as a result of the
        provisions herein and  specifically hereby negate any such intention.
         
             (e)  The Seller and each Asset Seller hereby consent to the
        hiring by the Buyer of employees of the Asset Sellers as contemplated
        by this Section 7.6  and waive, with respect to the employment of such
        employees, any  claims or rights that the Seller or any Asset Seller
        may have  against the Buyer or any such employee under any
        non-competition,  confidentiality or employment agreement.

             (f)  Except as specifically required by applicable law
        (including, without limitation, the Transfer Regulations) or as
        provided in this Section 7.6, the Buyer shall not have any obligation
        to employ or offer employment to any employees of the Asset Sellers
        employed in the Business.

        7.7  Employee Benefit Matters.  Contingent upon the occurrence of  the
   Closing:


        (a)  Transition Period for Foreign Retirement Plans.  The Seller shall
   make  such arrangements as may be necessary and possible for the Continuing
   Employees located outside of the U.S. to remain in the Foreign Retirement
   Plans for such period as the Buyer shall elect, of up to one year after the
   Closing Date (the "Foreign Transition Period"), and the Buyer shall bear
   the cost of such  coverage for the Continuing Employees during the  Foreign
   Transition Period at the contribution rate for  each such Foreign
   Retirement Plan being paid by the Seller on the  date of this Agreement,
   unless such rate is changed  (upward or downward) by the Buyer after the
   date  hereof, in which event the Buyer shall bear the cost of  such
   coverage for the Continuing Employees during the  Foreign Transition Period
   at the changed contribution  rate.  Notwithstanding the foregoing sentence,
   continued coverage of those Continuing Employees who are UK Employees in
   the Fisons UK Pension Fund shall be as set forth in Exhibit D.   In the
   event of any conflict between the terms and conditions hereof and the terms
   and conditions set forth in Exhibit D, the terms and conditions set forth
   in Exhibit D shall prevail.  The Seller and the Buyer shall observe and
   perform the provisions of Exhibit D to be performed by the Seller and the
   Buyer, respectively, in relation to the Fisons UK Pension Fund.  The
   foregoing provision of this Section 7.7(a) shall not apply to those Foreign
   Retirement Plans maintained by a Company solely for its employees.

                                       40PAGE

        (b)  Welfare Plans.

                  (i)  Benefits Continuation.  Except as provided in Sections
             7.7 (b)(ii),  (iii), (iv), (v), (vi), (vii) and (viii) below,
             effective as of the  Closing, (A) the Seller shall cause each
             Continuing  Employee to cease to participate in each welfare  
             benefit plan sponsored by the Asset Sellers, the Share  Sellers
             and/or their affiliates (the "Seller's Welfare  Plans") and
             (B) the Buyer shall cause each such Continuing Employee to be
             covered by Buyer's welfare  benefit plans.

                  (ii) Disability and Certain Other  Benefits.  The Seller
             shall be liable for claims for  benefits (other than for
             short-term disability, workers' compensation and medical

             benefits) by employees  of the Business (active or inactive) and
             by terminated  employees previously employed in the Business
             under the  Seller's Welfare Plans arising out of occurrences
             prior  to the Closing Date.  In this regard, but not by way of  
             limiting the foregoing, the Seller shall be liable for the
             long-term disability benefits for those employees of the Business
             receiving or qualified to receive long- term disability benefits
             under the Seller's disability programs as of the Closing Date,  
             including without limitation those employees of the Business in
             the long-term disability elimination period  (which employees
             shall receive long-term disability  benefits from the Seller upon
             the conclusion of the  applicable elimination period); provided,
             however, that the Seller's obligation to provide long-term
             disability benefits shall cease with respect to any such employee
             of the Business who subsequently becomes employed by the Buyer.

                  (iii)     Workers'  Compensation Benefits.  The Seller shall
             be liable for  claims for workers'  compensation benefits under
             the Seller's Welfare Plans  by employees of the Business (active
             or inactive) and by terminated employees previously employed in
             the Business with respect to injuries or illnesses prior  to the
             Closing Date.  The Buyer shall be liable for  claims for workers'
             compensation benefits by Continuing Employees with respect to
             claims for injuries or illnesses that occur on or after the
             Closing Date.

                  (iv) Short-Term Disability Benefits.  The Seller shall be
             liable for claims for short-term disability benefits under the
             Seller's Welfare Plans by employees of the Business (active or
             inactive) with respect to payments due prior to the Closing Date
             and by terminated employees previously employed in the Business.
             The Buyer shall be liable for claims for short-term disability
             benefits under the Buyer's welfare plans by Continuing Employees
             with respect to payments due on or after the Closing Date.  

                  (v)  Medical and Dental Benefits.  The Seller  shall be
             liable for claims for medical (including  vision care and
                                       41PAGE
<PAGE>
             prescription drugs) and dental benefits  incurred by employees of
             the Business (active or  inactive) and their respective covered
             dependents with respect to services and treatment rendered prior
             to the Closing Date under the Seller's Welfare Plans; provided,
             however, that the preceding provisions shall not alter any
             deadlines for submission of claims set forth in the Seller's
             Welfare Plans or increase any benefits, rights or remedies of the
             Continuing Employees under the Seller's Welfare Plans.  The Buyer
             shall be liable for claims for medical (including vision care and
             prescription drugs) and dental benefits incurred by Continuing
             Employees and their respective covered dependents under the
             Buyer's welfare plans with respect to services and treatment
             rendered on or after the Closing Date.  The Buyer shall cause
             each of the Continuing Employees to be granted credit under the
             Buyer's medical and dental plans, for the year during which the
             Closing Date occurs, with any deductibles or copayments already
             incurred by such Continuing Employees for such year under the
             plans of the Asset Sellers, the Share Sellers and/or their
             affiliates, but only if and to the extent that the amount of such
              incurred deductibles or copayments has been provided to the
             Buyer within 180 days after the Closing Date, and the Buyer shall
             cause to be waived any pre-existing condition restrictions under
             the Buyer's medical and dental plans to the extent necessary to
             provide immediate coverage under the Buyer's medical and dental
             plans.  The Buyer shall make available to the Continuing
             Employees (and their covered dependents) a group health plan (or
             plans) having a level of benefits such that the actual coverage
             of a Continuing Employee (or any of his or her covered
             dependents) under such group health plan (or plans) would, if the
             Continuing Employee had made an election under Section 4980B(f)
             of the Code or Part 6 of Title I of ERISA with respect to any
             group health plan maintained by any Asset Seller or any Share
             Seller, constitute an event described in Section
             4980B(f)(2)(B)(iv) of the Code and Section 602(2)(D) of ERISA.
             The Buyer shall have no obligation to provide health benefits to
             any Continuing Employee who declines to be covered under such
             group health plan (or plans) and, if the Buyer complies with the
             requirements of the preceding sentence, the Buyer shall have no
             further obligation or responsibility to any Asset Seller or any
             Share Seller under Section 4980B of the Code or Part 6 of Title I
             of ERISA with respect to the transactions contemplated by this
             Agreement.

                  (vi)      Transition Period.  Notwithstanding the
             foregoing, the Seller shall make such arrangements as  may be
             necessary for the UK Employees to  remain as participants of the
             Seller's private health insurance scheme after the Closing for a
             period of up to 90 days after the Closing Date  (as the Buyer
             shall elect) and the Buyer shall pay the premium cost for the
             participating UK Employees (and their covered dependents)
             incurred and paid after the Closing Date under the Seller's
             private health insurance scheme plus an administrative fee of 5%
                                       42PAGE

             of such cost.


                  (vii)     Retiree Medical, Dental and Life Benefits.   The
             Seller shall be liable for medical, dental and life  insurance
             coverage under the Seller's Welfare Plans after termination of
             employment to employees of the Business whose  employment
             terminated prior to the Closing Date and to those  employees of
             the Business who are eligible therefor as of  the Closing Date.
             Prior to the Closing Date, the Seller  agrees to notify all
             employees of the Business that such  coverage (including coverage
             under the Fisons Post-Retirement Medical Savings Plan) for all
             employees of the Business will be  terminated upon the Closing
             Date and it will notify Continuing Employees who are eligible as
             of the Closing Date for retiree medical coverage under the ARL
             retiree medical plan which provides for medicare supplemental
             coverage that coverage for such Continuing Employees under such
             plan as in effect from time to time will be provided by the
             Seller upon retirement from the  Buyer and/or its affiliates.
             The Buyer agrees to provide  notice to the Seller of such
             retirements for purposes of the  preceding sentence.

                       (viii)       COBRA.   The Seller shall be responsible
             for providing benefits pursuant to Section 4980B of the Code to
             employees of the Business who cease to be employed by any
             Company or Asset Seller prior to the Closing Date.

                      (ix)        Limitation on Buyer's Liability.  Except as
             provided in this Section 7.7(b),  the Buyer shall have no
             liability with respect to any claims for benefits under the
             Seller's Welfare Benefit Plans.  The Seller shall have no
             liability with respect to claims for benefits under the Buyer's
             welfare benefit plans.

             (c)  Multi-employer Plans.  The Buyer, the Companies and/or their
        affiliates shall not assume any  obligation or liability imposed under
        Section 4201 of ERISA.   The Buyer, the Companies and/or their
        affiliates  shall not be obligated under any agreement described in  
        Section 4204 of ERISA.

             (d)  Savings Plans.  The Buyer shall allow U.S. Continuing
        Employees to make direct cash rollovers under Section 402(c) of the
        Code of their account balances from the Savings Plan to a savings plan
        intended to be qualified under Section 401(a) of the Code maintained
        by the Buyer.  The parties agree to take such action as is reasonably
        necessary to establish an arrangement under which any U.S. Continuing
        Employee may provide for payroll withholding for the purpose of
        repaying any loan made prior to the Closing Date to such Continuing
        Employee by the Savings Plan, in lieu of payment of the loan in full
        as a result of the transactions contemplated by this Agreement.

        than sixty (60) days after the Closing Date, it will forward to the
        Seller (ATTN:  Manager, Retirement Programs) within ten (10) days
        after the end of each month a written list, prepared by the Buyer's
        payroll department of all Continuing Employees who have terminated

        Closing Date (or longer if required by any applicable statute of
        limitations) the books and records relating to the Business
        transferred pursuant to this Agreement (unless the Seller requests a
        longer period, in which case such books and records shall be  stored
        by the Buyer at the Seller's expense), and, during  normal business
        hours, with reasonable advance notice and in  such manner as not to
        interfere unreasonably with the normal  business operations of the
        Buyer, shall (i) give the Seller and  its authorized representatives

             (b)  The Seller shall and shall cause each Share Seller and Asset
        Seller to retain for a period of seven years after the Closing Date

        generality of the foregoing, the Seller shall make  available to the

             aggregate amount of such Taxes exceeds the aggregate amount of
             the reserves and accruals for Taxes set forth on the Closing

             transactions or events contemplated by this Agreement that occur
             at or prior to the Closing shall be deemed to have occurred in
             the Pre-Closing Period.

        (c)  In the case of any Tax that is attributable to a taxable period
        which begins before the Closing Date and ends on or after the Closing

             Asset Seller or any Company and franchise or similar Taxes
             imposed on any Company based on capital (including net worth or
             long-term debt) or number of shares of stock authorized, issued
             or outstanding, the portion attributable to the Pre-Closing
             Period shall be the amount of such Taxes for the entire taxable
             period multiplied by a fraction, the numerator of which is the
             number of days in the Pre-Closing Period and the denominator of
             which is the number of days in the entire taxable period.

             (ii) In the case of all other Taxes, the portion attributable to
             the Pre-Closing Period shall be determined on the basis of an
             interim closing of the books of the Company or Asset Seller as of
             the Closing, and the determination of the hypothetical Tax for
             such Pre-Closing Period, determined on the basis of such interim
             closing of the books, without annualization.  The hypothetical
             Tax for any period shall in no case be less than zero.  

        (d)  The Buyer and the Seller shall cooperate fully, as and to the
        extent reasonably requested by the other party, in connection with the
        filing of Tax Returns and any audit, litigation or other proceeding
        with respect to Taxes.  Such cooperation shall include the retention
        and (upon the other party's request) the provision of records and
        information which are reasonably relevant to any such audit,
        litigation or other proceeding and making employees available on a
        mutually convenient basis to provide additional information and
        explanation of any material provided hereunder; provided that the
        party requesting assistance shall pay the reasonable out-of-pocket
        expenses incurred by the party providing such assistance; and provided
        further that no party shall be required to provide assistance at times
        or in amounts that would interfere unreasonably with the business and
        operations of such party.  The Buyer agrees to retain all books and
        records with respect to Tax matters pertinent to the Companies or the
        Business relating to any Tax periods ending on or prior to the Closing
        Date and any Tax periods beginning before the Closing Date and ending
        after the Closing Date until the expiration of any applicable statute
        of limitations or extensions thereof.  The Seller and Buyer
        acknowledge the difficulty of providing such cooperation; accordingly,
        the Seller and Buyer agree to use reasonable efforts to request any
        assistance pursuant to this Section 7.9(d) within the first six months
        following the Closing Date.  Without limiting the generality of the
        foregoing provisions of this Section 7.9(d), the Seller (and each
                                       46PAGE
<PAGE>
        Share Seller and Asset Seller) and the Buyer shall cooperate and
        consult in good faith with each other during the course of the
        preparation of foreign, federal, state and local income Tax Returns
        which include Pre-Closing Periods and to the extent appropriate shall
        use their best efforts to agree on the inclusion of items of income,
        deduction, gain, loss and credit for each Pre-Closing Period so as to
        properly reflect such items attributable to such Pre-Closing Period in
        a manner consistent with past practices.

             (e)  The Buyer and Seller agree that to the maximum extent
        permitted by applicable law, neither the Buyer nor any of the Buyer's
        affiliates or subsidiary corporations (including, with respect to
        Post-Closing Periods, the Companies) will carry back to any taxable
        period of the Seller or any of its Subsidiaries or Affiliates
        (including, with respect to Pre-Closing Periods, the Companies) any
        loss, credit or deduction incurred or generated in, or attributable
        to, any Post-Closing Period that would affect any Tax Return of the
        Seller or any of its Subsidiaries or Affiliates, and the Buyer agrees
        to make or exercise, or cause to be made or exercised, any and all
        necessary or permitted elections or options available under applicable
        law to avoid any such carryback.

             (f)  Notice and indemnification in connection with Taxes shall be
        governed by Section 11 of this Agreement.

             (g)  All indemnification payments under Section 11 shall be
        deemed adjustments to the Purchase Price.

             (h)  United Kingdom Value Added Tax

             (i)  The Seller and the Buyer intend that article 5 of the United
             Kingdom Value Added Tax (Special Provisions) Order 1992 (the "VAT
             Order") shall apply to the sale of the Assets located in the
             United Kingdom (the "UK Assets") under this Agreement, so that
             the sale is treated as neither a supply of goods nor a supply of
             services.

             (ii) If nevertheless any United Kingdom VAT ("UK VAT") is
             chargeable on any supply by the Seller under this Agreement, the
             Buyer shall pay to the Seller the amount of that UK VAT (and
             indemnify it for any related interest and penalties) and the
             Seller shall issue to the Buyer a proper tax invoice in respect
             of that UK VAT.

             (iii)     Without limiting clause (ii) above, UK VAT shall be
             treated as chargeable if HM Customs & Excise rule that it is
             chargeable.  If they have done so before Closing, the UK VAT
             shall be payable by the Buyer on Closing subject to delivery at
             Closing by the Seller to the Buyer of the appropriate tax
             invoice.  If they do so on or after Closing, the UK VAT shall be
             payable by the Buyer within five days after the Seller gives the
             Buyer notice of the ruling together with the appropriate tax
                                       47PAGE
<PAGE>
             invoice.

             (iv) If the Buyer fails to pay the amount of the UK VAT on the
             due date under clause (iii) above, it shall pay interest on that
             amount from the due date until actual payment (excluding any
             period for which interest indemnified under clause (ii) runs) at
             an interest rate equal to one percent above LIBOR, as in effect
             from time to time.

             (v)  With a view to ensuring that article 5 of the VAT Order
             applies, the Buyer:

                  (a)  shall ensure that the Buyer is registered in the United
                  Kingdom for UK VAT not later than the Closing Date; 

                  (b)  warrants that the UK Assets are to be used by the Buyer
                  in carrying on the same kind of business as that carried on
                  by the Seller in relation to the UK Assets; and

                  (c)  warrants that the Buyer has, or will by the relevant
                  date have, properly made an election to waive exemption in
                  respect of Unit TX, Churchfields Industrial Estate, Sydney
                  Little Road, East Sussex, England, United Kingdom, with
                  effect from a day not later than the relevant date (having
                  obtained the written permission of HM Customs and Excise if
                  necessary) which it will not revoke within three months of
                  the Closing Date and has, or will by that date have, duly
                  given to HM Customs and Excise the written notification of
                  the election required to make the election effective.  In
                  this paragraph "relevant date" has the same meaning as
                  article 5(2) of the VAT Order.

             (vi) In respect of each property mentioned in clause (v)(c),
             without prejudice to that subclause, the Buyer shall on or before
             the Closing give to the Seller evidence reasonably satisfactory
             to the Seller that the election has been made and written
             notification duly given in accordance with that subclause.

             (vii)     References in clauses (v)(a) and (c) to the Buyer shall
             be construed as references to the transferee within the meaning
             of the corresponding provision of article 5 of the VAT Order.

             (viii)    The Seller and the Buyer intend that Section 49 of the
             Value Added Tax Act 1994 shall apply to the sale of the Assets
             under this Agreement.  The Buyer will allow the Seller access to
             and copies of any UK VAT records of the Business which are
             preserved by the Buyer pursuant to Section 49(1)(b) of the United
             Kingdom Value Added Tax Act 1994 in accordance with Section 7.8
             of this Agreement.

        7.10 Certain Trademark Matters.

             (a)  The Buyer shall not, and shall cause its Subsidiaries not
        to, put into use after the Closing Date any products, signs, purchase
        orders, invoices, sales orders, labels, letterheads, shipping
        documents and other materials not in existence on the Closing Date
        that bear any of the Retained Names and Logos or any name, mark or
        logo similar thereto.  The Buyer shall be entitled to use any
        products, signs, purchase orders, invoices, sales orders, labels,
        letterheads, shipping documents or other materials in existence as of
        the Closing Date that bear any of the Retained Names and Logos or any
        name, mark or logo similar thereto for such period after the Closing
        Date, not exceeding 180 days, as the Buyer reasonably requires in
        order to (i) sell, in the Ordinary Course of Business, the inventory
        purchased by the Buyer hereunder and (ii) effect an orderly transition
        of the Business; provided, however, that (x) any such use shall be
        subject to such control policies and mechanisms as the Seller may
        reasonably impose and (y) the Seller shall be entitled to conduct such
        investigations of such use as it may reasonably deem necessary to
        protect its interests in the Retained Names and Logos and to satisfy
        itself of the Buyer's compliance with the provisions of this Section
        7.10(a).  The Buyer agrees that the Seller shall have no
        responsibility for claims by third parties arising out of, or relating
        to, the use by the Buyer or any successor thereof of any of the
        Retained Names and Logos after the Closing Date. 

             (b)  The Seller agrees, for itself and on behalf of its
        Subsidiaries and Affiliates, not to use, after the Closing Date, any
        trademark (other than the Retained Names and Logos) conveyed by the
        Seller to the Buyer hereunder or any trademark or name confusingly
        similar to any of the foregoing.   The Seller shall promptly amend the
        certificate  of incorporation and other corporate records of its
        Subsidiaries as necessary to comply with this  provision or, in the
        United Kingdom, change the name of such Subsidiaries.

        7.11 Notice of Breaches; Updates.

             (a)  The Seller shall promptly deliver to the Buyer written
        notice of any event or development that would (i) render any
        statement, representation or warranty of the  Seller in this Agreement
        (including exceptions set forth in  the Schedules) inaccurate or
        incomplete in any  material respect, or (ii) constitute or result in a
        breach by the Seller of, or a failure by the Seller to comply in any
        material respect with,  any agreement or covenant in this Agreement
        applicable to  the Seller.   No such disclosure shall be deemed to
        avoid or  cure any such misrepresentation or breach.

             (b)  The Buyer shall promptly deliver to the Seller written
        notice of any event or development that would  (i) render any
        statement, representation or warranty of the  Buyer in this Agreement
        inaccurate or incomplete in any  material respect, or (ii) constitute
        or result in a breach by  the Buyer of, or a failure by the Buyer to
                                       49PAGE
<PAGE>
        comply with, any  agreement or covenant in this Agreement applicable
        to the  Buyer.   No such disclosure shall be deemed to avoid or cure  
        any such misrepresentation or breach.

             (c)  The Seller shall deliver to the Buyer, as promptly as
        practicable following the end of each calendar month ending after the
        date of this Agreement and prior to the  Closing Date, an unaudited
        combined  statement of operations of the Business, and such other  
        internal financial information as is ordinarily prepared by  the
        Seller with respect to the Business, for such month, in  each case
        prepared in accordance with past practices.

        7.12 Proprietary Information.  From and after the Closing,  the Seller
   shall, and shall cause the Asset Sellers, the Share  Sellers and its other
   Subsidiaries and Affiliates to, hold in confidence all  knowledge,
   information and documents of a confidential nature or  not generally known
   to the public with respect to the Business or  the Buyer or the Buyer's
   business (including without limitation  the financial information,
   technical information or data relating  to the products of the Business and
   the names of customers of the  Business) and shall not disclose or make use
   of the same without the written consent of the Buyer, except (i) as may be
   required by applicable law, (ii) that the Seller may disclose any such
   information to its professional advisors who need to know such information
   to assist Seller in complying with applicable tax, accounting, securities
   or other laws, rules or regulations and who agree to be bound by the
   provisions of this Section 7.12, (iii) as may be required by reporting
   requirements of any stock exchange or any lawful proceeding of a
   Governmental Body, provided that the Seller shall provide the Buyer with
   notice of any such disclosure as far in advance of such disclosure as is
   reasonable under the circumstances and that the Seller will cooperate
   reasonably with the Buyer to minimize the scope of such disclosure, and
   (iv) to the extent that such  knowledge, information or documents shall
   have become public  knowledge other than through a breach of this Agreement
   by the Seller, its Subsidiaries or Affiliates. 

        7.13 Solicitation.  For a period of two years  after the Closing Date,
   the Seller shall not, and shall cause its Subsidiaries and Affiliates not
   to, either directly or indirectly as a  stockholder, investor, partner,
   director, officer, employee or  otherwise, solicit or attempt to induce any
   Restricted  Employee to terminate his or her employment with the Buyer or
   any Affiliate of the Buyer; provided, however, that it shall not be a
   breach of this Section 7.13 for the Seller to solicit Restricted Employees
   by means of general public advertisements or recruitment through an
   employment agency.  For purposes of this Agreement, a "Restricted Employee"
   shall  mean any person, other than employees terminated involuntarily by
   the Buyer,  who (i) either (A) hold or have access to trade secrets or
   other confidential information relating to the Business or (B) had annual
   base salary in 1994 of at least 75,000 English pounds sterling, and (ii)
   either (X) was an employee of the Buyer or any Affiliate of  the Buyer on
   either the date of this Agreement or the Closing  Date or (Y) was an
   employee of any  Asset Seller (employed primarily in the Business) or
   Company on either the date  of this Agreement or the Closing Date and who
                                       50PAGE
<PAGE>
   is employed by the Buyer immediately after the Closing.


        7.14 Non-Competition.

             (a)  For a period of five years after the Closing Date, the
        Seller shall not, and shall cause its Subsidiaries not to, either
        directly or indirectly as a stockholder, investor,  partner, director,
        officer, employee, consultant or  otherwise, engage in a Competitive
        Business in any territory.   For purposes of this Agreement, a
        "Competitive Business" means (i) the development, manufacture,
        marketing or sale of any product which is competitive with any product
        manufactured,  sold or developed (or under development) by the
        Business on  or prior to the Closing Date or (ii) the rendering of or
        marketing of any  service which is competitive with any service
        rendered or  marketed (or proposed to be rendered or marketed) by the
        Business on or prior to the Closing Date; provided, however, that the
        Seller shall not be prohibited from (1) the acquisition by asset
        purchase, stock purchase, merger, consolidation or otherwise of any
        Person partially engaged in a Competitive Business if the Seller uses
        its best efforts to dispose of the portion of such Person engaged in
        the Competitive Business within 12 months after such acquisition and,
        if such portion has not been disposed of within such 12-month period,
        the Seller continues to use all reasonable efforts to dispose of such
        portion, (2) the ownership of not more than 10% of any class of debt
        or equity securities of any Person engaged in a Competitive Business
        or (3) continuing to conduct and develop its Pharmaceuticals and
        Laboratory Supplies Divisions, the latter of which distributes or may
        distribute products for third parties that are or may be competitive
        with products manufactured or sold by the Business, provided, however,
        that such Divisions shall not in any event manufacture instruments of
        the type manufactured by the Business as of the Closing.

             (b)  The Seller agrees that the duration and geographic scope of
        the non-competition provision set forth in this Section 7.14 are
        reasonable.   In the event that any court  determines that the
        duration or the geographic scope, or  both, are unreasonable and that
        such provision is to that  extent unenforceable, the parties agree
        that the provision  shall remain in full force and effect for the
        greatest time  period and in the greatest area that would not render
        it  unenforceable.  The parties intend that this non-competition  
        provision shall be deemed to be a series of separate  covenants, one
        for each and every county of each and every  state of the U.S. and
        each and every political subdivision  of each and every country
        outside the U.S. where this  provision is intended to be effective.

        7.15 Cooperation in Litigation.  From and after the Closing  Date,
   each party shall fully cooperate with the other in the  defense or
   prosecution of any litigation or proceeding already  instituted or which
   may be instituted hereafter against or by  such other party relating to or
   arising out of the conduct of the  Business by the Seller or the Buyer or
   their respective Affiliates prior to or after the Closing Date (other than
                                       51PAGE
<PAGE>
   litigation among the Seller and the Buyer and/or their respective
   Subsidiaries, Affiliates or parent companies arising out the transactions
   contemplated by this Agreement).  The party requesting such cooperation
   shall pay the  reasonable out-of-pocket expenses incurred in providing such
   cooperation (including legal fees and disbursements) by the party  
   providing such cooperation and by its officers, directors,  employees and
   agents, but shall not be responsible for  reimbursing such party or its
   officers, directors, employees and  agents for their time spent in such
   cooperation.

        7.16 Collection of Accounts Receivable.

             (a)  The Seller agrees that it shall, and shall cause the Share
        Sellers and the Asset Sellers to, forward promptly to the Buyer any
        moneys, checks or instruments received by any of them after the
        Closing Date with  respect to the accounts receivable purchased by the
        Buyer  pursuant to this Agreement.   The Seller shall, and shall cause
         the Share Sellers and the Asset Sellers to, provide to the Buyer  
        such reasonable assistance as the Buyer may request with respect  to
        the collection of any such accounts receivable, provided the  Buyer
        pays the reasonable out-of-pocket expenses of the Seller  and its
        officers, directors and employees incurred in providing  such
        assistance.

             (b)  For a period of 12 months after the Closing Date (the
        "Collection Period"), the Buyer shall use its reasonable efforts to
        collect the accounts receivable shown on the Closing Balance Sheet
        (the "Accounts Receivable").  The Buyer may, but shall not be
        obligated to, use a collection agency or commence legal actions in
        connection with such collection efforts.  Promptly after the
        expiration of the Collection Period, the Buyer shall give notice to
        the Seller designating those Accounts Receivable which have not been
        collected as of the end of the Collection Period and which the Buyer
        wishes the Seller to purchase.  Within ten days after the receipt of
        such notice from the Buyer, the Seller shall purchase (without
        recourse to the Buyer) such designated Accounts Receivable then
        remaining unpaid for a purchase price equal to the value of such
        Accounts Receivable recorded on the Closing Balance Sheet less the
        reserve for doubtful accounts shown on the Closing Balance Sheet.
        References to Seller shall include, for purposes of Sections
        7.16(b)-(f), an Affiliate of Seller nominated by Seller.  

             (c)  Upon the Seller's repurchase of any unpaid Account
        Receivable pursuant to this Section 7.16, the Buyer shall promptly
        deliver to the Seller any tangible evidence of such Account Receivable
        then in the possession of the Buyer or under its control but in any
        event the Buyer shall preserve and make available to the Seller all
        documentation in relation to such Account Receivables received by the
        Buyer from the Seller at Closing.

             (d)  In the event that any payment received by the Buyer during
        the Collection Period is remitted by a customer which is indebted
                                       52PAGE
<PAGE>
        under both Accounts Receivable and an account receivable arising out
        of the sale of inventory in the Ordinary Course of Business after the
        Closing Date (a "New Receivable"), such payments shall first be
        applied to the Accounts Receivable due from such customer and the
        balance remaining after payment in full of all Accounts Receivable due
        from such customer shall be applied to the New Receivable; provided,
        however, that (i) with respect to any Account Receivable being
        contested or disputed by the payor thereof, no portion of the amount
        in dispute shall be deemed to have been collected by the Buyer in
        respect of such Account Receivable (unless otherwise directed by the
        customer) until all amounts owed by such customer to the Buyer for New
        Receivables have been paid or such dispute has been resolved,
        whichever occurs first (it being understood that undisputed amounts of
        Accounts Receivable shall be applied in accordance with the priorities
        set forth above) and (ii) the foregoing priorities shall not apply to
        sums received by the Buyer which are specifically identified by the
        customer as being tendered in payment of a New Receivable.  The Buyer
        agrees not to induce any customer to identify any payment as being in
        respect of a New Receivable, except in the event the Buyer reasonably
        determines to sell to said customer on a  C.O.D. basis only.

             (e)  The Buyer will reasonably cooperate, at the Seller's
        expense, with the Seller in collecting any Accounts Receivable which
        are repurchased by the Seller pursuant to this Section 7.16; provided,
        however, that the foregoing shall not require the Buyer to be a party
        to any action brought by the Seller to collect such Accounts
        Receivable unless the conveyance of the Account Receivable to Seller
        is ineffective and Buyer is deemed to hold title thereto.

             (f)  Any sums received by the Buyer in respect of Accounts
        Receivable after their repurchase by the Seller pursuant to this
        Section 7.16 shall be promptly transmitted by the Buyer to the Seller.
        In addition, if receipt by the Buyer of unidentified sums of money
        from an account debtor who owes any Account Receivable repurchased by
        the Seller pursuant to this Section 7.16 results in such account
        debtor having an aggregate credit balance with the Buyer, the Buyer
        shall promptly transmit to the Seller an amount of money equal to the
        lesser of (a) such aggregate credit balance or (b) the remaining
        unpaid balance of all Accounts Receivable which have been repurchased
        by the Seller and are payable by such account debtor to the Seller.
         

        7.17 Approval of Seller's Shareholders.  The Seller shall convene a
   general meeting of its shareholders for the purpose of considering and, if
   thought fit, passing a resolution (the "Seller's Shareholder Resolution")
   approving the sales of the Assets and the Shares pursuant to the terms of
   this Agreement.  Such meeting shall be held not later than 35 days after
   the date of this Agreement.  Notice of such meeting shall be accompanied by
   a recommendation of the Board of Directors of the Seller in favor of the
   Seller's Shareholder Resolution. The Seller shall ensure that such
   recommendation is not changed or withdrawn prior to the vote upon the
   Seller's Shareholder Resolution unless the failure to change or withdraw
                                       53PAGE
<PAGE>
   such recommendation would be a breach by the directors of the Seller of
   their fiduciary duty as directors under applicable law.  Seller shall
   provide Buyer with a reasonable opportunity to review and comment upon the
   content of any circular or other shareholder communication insofar as it
   relates to the Buyer or the transactions contemplated hereby. 

        7.18 Bank Accounts.  Prior to Closing, Seller shall provide Buyer with
   a complete list and description of all bank accounts, brokerage accounts,
   marketable securities, lines of credit, guaranties, foreign exchange option
   or forward contracts, and letters of credit held by any of the Companies
   or, in the conduct of the Business, the Asset Sellers or to which the
   Companies, or in the conduct of the Business, the Asset Seller are parties.
   Buyer and Seller will cooperate so that, as of the Closing, Buyer shall
   have the benefit of any such assets and, except as otherwise provided
   herein, shall (if permitted) be substituted for the Asset Sellers on any
   such contracts or agreements. 

        7.19 Transition Services.  At and conditioned upon the Closing, the
   Buyer and the Seller (or one of its Affiliates) shall enter into an
   agreement (the "Transition Services Agreement") that shall identify
   specifically the transition services to be provided (for a maximum period
   of six months unless mutually agreed otherwise) by the Seller or its
   Affiliates in each jurisdiction in which the Business is conducted.  The
   Buyer shall pay the Seller a fee for such services equal to the fully
   allocated cost of such services to the Seller, plus an administrative fee
   of 5% of such costs, within 30 days of billing thereof.

        7.20 Guarantee.  The Parent hereby guarantees the prompt and complete
   performance by the Buyer of all of the Buyer's covenants and conditions
   hereunder, which guarantee shall continue until all of the terms of this
   Agreement to be performed by the Buyer have been performed or otherwise
   discharged.

        7.21 Employee Notices.  The Seller shall make or shall cause the
   Companies and Asset Sellers to make, such notices to employees as shall be
   required by applicable law or agreement (including any notices required to
   be given to any union, works council or similar representative body).

        7.22 Seller's Disclosure.     The Seller has provided the Buyer with
   reasonable access to (i) copies of all agreements or documents described in
   the Schedules and (ii) reasonably detailed descriptions of all claims,
   proceedings or other matters described in the Schedules (any such
   agreement, document or description being referred to herein as a "Disclosed
   Item").  For purposes of the preceding sentence, the Seller shall be deemed
   to have provided Buyer with reasonable access to a Disclosed Item if such
   Disclosed Item was (a) physically provided to the Buyer, its Subsidiaries,
   Affiliates or representatives not later than February 24, 1995, or (b) held
   and available for review as of February 24, 1995 at the law firm listed on
   the attached Schedule 7.22 located in the same country as the Asset Seller
   or Company to which such Disclosure Item relates.  Notwithstanding the
   foregoing, the Seller shall not in any event be deemed to have provided
   Buyer with reasonable access to any Disclosed Item located at any law firm
                                       54PAGE
<PAGE>
   outside of the U.S., England, Germany, Switzerland and Italy if such
   Disclosed Item is not listed on the attached Schedule 7.22A or has not
   physically been provided to Buyer, its Subsidiaries, Affiliates or
   representatives not later than February 24, 1995.  The effect of any
   failure by Seller to provide Buyer access to a Disclosed Item as provided
   in this Section 7.22 shall be that such Disclosed Item shall be deemed not
   to be disclosed on the Schedules, notwithstanding its appearance on the
   Schedules.

                                       59PAGE
<PAGE>
             (g)  (expressions used in this paragraph (g) have the same
       meanings as in Exhibit D) any claim which arises in consequence of
       Regulation 7 of the Transfer Regulations causing liabilities relating
       to the Fund not to transfer to the Buyer as mentioned in that
       Regulation and which relate to a UK Employee (or to any spouse or
       dependent of a UK Employee) who has not been provided with the whole or
       any part of any benefit as provided under the Fund (whether in relation
       to employment before or after the Closing Date) or any claim relating
       to the cost of such benefit, but excluding any claim arising out of (i)
       a breach of contract by the Seller (other than a claim in consequence
       of the Buyer not providing benefits which are equivalent to those
       provided under the Fund); (ii) a breach of trust in relation to the
       Fund; and (iii) any claim by a Consenting Member in relation to the

       payment of the Transfer Amount in accordance with  Exhibit D.

       11.3  Limitations on Indemnification.

             (a)  Except as provided in Section 11.3(c)(ii) or Section 8.2,
       each party's obligation to indemnify the other for Losses arising under
       Section 11.1(a) or Section 11.2(a), as the case may be, shall be
       limited as to amount, as follows:

                 (i)   The Indemnitor shall not be required to indemnify the
             Indemnitee for any Loss except to the extent that the amount of
             such Loss, when added to the aggregate amount of all other Losses
             indemnifiable under this Section 11, exceeds 2,000,000 English
             pounds sterling (the "Indemnification Threshold"); 

                (ii)   The Indemnitor shall not be required to indemnify the
             Indemnitee for any Losses which, when added to the aggregate
             amount of all other Losses indemnifiable under this Section 11,
             exceed one-half (1/2) of the Purchase Price in the aggregate; and

               (iii)   The Indemnitor shall not be required to indemnify the
             Indemnitee for Losses indemnifiable under this Section 11 if the
             claim for indemnification involves less than 100,000 English
             pounds sterling (the "Minimum Claim Amount"); provided, however,
             that (W) until the Indemnification Threshold is exceeded, the
             Minimum Claim Amount shall be reduced to 5,000 English pounds
             sterling for purposes of the application of otherwise
             indemnifiable Losses toward the Indemnification Threshold, (X)
             for purposes of determining whether the Minimum Claim Amount has
             been exceeded, all claims arising out of the same or similar
             circumstances shall be treated as a single claim, and (Y) after
             the Indemnification Threshold has been exceeded, with respect to
             any indemnifiable claim that exceeds the Minimum Claim Amount,
             the entire claim (not just the amount in excess of 100,000
             English pounds sterling) shall be indemnifiable.

<PAGE>
             (b)  Except as provided in Section 11.3(c)(i), neither the Seller
       nor the Buyer shall be entitled to make any claim for indemnification
       arising under Section 11.1(a) or Section 11.2(a), as the case may be,
       after the date that is 18 calendar months after the Closing Date,
       unless the Seller or the Buyer, as the case may be, shall have asserted
       such claim for indemnification prior to such date, stating with
       reasonable specificity the nature, facts and circumstances of such
       claim in which event such claim shall survive until the resolution
       thereof.  If a claim for indemnification is asserted prior to the
       applicable expiration date, then (notwithstanding the expiration of
       such time period) the representation or warranty applicable to such
       claim shall survive until the resolution of such claim. 

             (c)  Notwithstanding any other provision to the contrary herein:

                 (i)   the representations contained in Section 5.2,
             Section 5.3, Section 5.4 (to the extent that any breach of
             representation or warranty arising under Section 5.4 relates to
             the right of any person or entity, including, without limitation,
             any Governmental Body, to cause the transactions completed by
             this Agreement to be rescinded following consummation) and
             Section 5.9(a) shall survive without time limit;  

                (ii)   none of the provisions of Section 11.3(a) shall apply
             with respect to Losses arising from breaches of the
             representations described in Section 11.3(c)(i), and the maximum
             amount of Losses for which an Indemnitor shall be liable with
             respect to such Losses shall be equal to the Purchase Price; and

               (iii)   the Buyer and the Parent shall not be required to
             indemnify the Seller and its Affiliates under Section 11.2(g) for
             Losses, when added to the aggregate amount of all other Losses
             indemnifiable under Section 11.2(g), exceeds 1,000,000 English
             pounds sterling.

             (d)  Except with respect to claims based on actual fraud, the
       rights of the Buyer and the Seller under this Section 11 shall be the
       exclusive remedy of the Buyer and the Seller, respectively, with
       respect to claims resulting from or relating to (X) any breach of
       representation or warranty or failure to perform any covenant or
       agreement of the Seller or the Parent or Buyer, respectively, contained
       in this Agreement, or (Y) any Excluded Liabilities.  

       11.4  Third-Party Claims.

             (a)  In the event that any legal proceedings shall be instituted
       or any claim or demand shall be asserted by any Person other than a
       party hereto or any Affiliate of a party hereto (other than an officer,
       director or holder of more than 10% of the stock of such party) (a
       "Third-Party Claim") in respect of which indemnification may be sought
       by any party or parties from any other party or parties under the
       provisions of this Section 11, the party or parties that may seek
                                       61PAGE
<PAGE>
       indemnification (collectively, the "Indemnitee") shall cause written
       notice in reasonable detail of the assertion of any Third-Party Claim
       of which it has knowledge that is covered by this indemnity to be
       forwarded promptly to the party from which indemnification may be
       sought (the "Indemnitor"); provided that, if any taxing authority
       proposes an adjustment, questions the treatment of any item, or
       commences an examination or audit, which adjustment, question,
       examination or audit could, if pursued successfully, reasonably be
       expected to give rise to a claim relating to Section 5.8 or  Section
       7.9 (a "Tax Dispute"), then such Tax Dispute shall constitute a
       Third-Party Claim under this Section 11.4, and the party hereto first
       receiving notice of such Tax Dispute shall promptly notify in writing
       the other party hereto; provided further that the failure of an
       Indemnitee to give timely notice shall not affect rights to
       indemnification hereunder except to the extent that the Indemnitor has
       been damaged by such failure.  The Indemnitor shall have the right, at
       its option and at its  own expense, to be represented by counsel of its
       choice and  to participate in the defense, negotiation and/or
       settlement  of any Third-Party Claim.

             (b)  In connection with any Third-Party Claim, the Indemnitor, at
       the sole cost and expense of the Indemnitor, may, upon written notice
       to the Indemnitee, assume the  defense of any such Third-Party Claim if
       (i) the Indemnitor  acknowledges in writing the obligation of the
       Indemnitor to  indemnify in accordance with the terms of this Agreement
       the  Indemnitee with respect to such Third-Party Claim, (ii) the  
       Third-Party Claim seeks monetary damages solely or is a Tax Dispute and
       (iii) an adverse resolution of the Third-Party Claim would not have a  
       material adverse effect on the goodwill or reputation of or the future
       conduct of the business of the Indemnitee; provided, however, that the
       Indemnitee may  participate in any such proceeding with counsel of its
       choice  and at its own expense; and provided further, however, that  if
       the Indemnitor assumes control of such defense and the Indemnitee
       reasonably concludes that the Indemnitor and the  Indemnitee have
       conflicting interests or different defenses  available with respect to
       such action, suit or proceeding,  or if the Indemnitor elects not to
       assume such defense, then the reasonable fees and expenses of counsel
       to the Indemnitee  shall be considered "Losses"  for purposes of this
       Agreement.  The party controlling such defense shall keep the other
       party  advised of the status of such action, suit or proceeding and  
       the defense thereof and shall consider in good faith  recommendations
       made by the other party with respect thereto.

             (c)  The Indemnitee shall not agree to any settlement of such
       action, suit or proceeding without the prior written consent of the
       Indemnitor, which shall not be unreasonably  withheld, unless the
       Indemnitee waives any right to indemnity  therefor by the Indemnitor.
        Notwithstanding the foregoing,  if a customer or a supplier of the
       Business asserts that the  Buyer is liable to such customer or supplier
       for a monetary  or other obligation which may constitute or result in
       Losses  for which the Buyer may be entitled to indemnification  
       pursuant to this Section 11 and the Buyer reasonably  determines that
                                       62PAGE
<PAGE>
       it has a valid business reason to fulfill  such obligations, then (i)
       the Buyer shall be entitled to  satisfy such obligation without prior
       notice to or consent  from the Seller, (ii) the Buyer may make a claim
       for  indemnification pursuant to this Section 11 and (iii) the Buyer  
       shall be reimbursed, in accordance with the provisions of  this
       Section 11, for any such Losses for which it is entitled to  
       indemnification pursuant to the provisions of this Section 11;  
       provided, however, that if the Buyer makes a claim for  indemnification
       in accordance with this sentence the Seller  shall not be deemed to
       have waived any defense to such claim  by the Buyer, notwithstanding
       the Buyer's prior satisfaction  of the obligation for which
       indemnification is sought, and it  shall not be a defense to the
       Buyer's claim for  indemnification that the Buyer has satisfied the
       obligation  for which indemnification is sought.

             (d)  After final judgment or award shall have been rendered by a
       court, arbitration board or administrative agency of competent
       jurisdiction and the expiration of the  time in which to appeal
       therefrom, or a settlement shall have  been consummated, or the
       Indemnitee and the Indemnitor shall  have arrived at a mutually binding
       agreement with respect to  each separate matter indemnified by the
       Indemnitor, the  Indemnitee shall forward to the Indemnitor notice of
       any sums  due and owing hereunder by the Indemnitor with respect to
       such matter and the Indemnitor shall pay all of the sums so owing to
       the  Indemnitee by check within 30 days after the date of such  notice.
       Any payment not made when due under this Section 11 shall bear
       interest, compounded monthly on the last day of each calendar month,
       from the due date, at an interest rate equal to one percent above
       LIBOR, as in effect from time to time.

   12. TERMINATION.

       12.1  Termination Events.  Subject to the other provisions of  this
   Section 12, this Agreement may, by written notice given at or  prior to the
   Closing in the manner hereinafter provided, be  terminated and abandoned:

             (a)  By either the Seller or the Buyer if a material default or
       breach shall be made by the other with respect to (i) the due and
       timely performance of any of its covenants and  agreements contained
       herein, or (ii) the due compliance with any of its representations and
       warranties  contained in Sections 5 or 6, as the case may be, except
       (in the case of Seller) for any lack of compliance that arises from an
       event or condition that (together with all other events or conditions)
       would not be a Material Event, and such breach or default has not been
       (i) cured within 15 days after notice thereof is given to the breaching
       party or (ii) waived by the non-breaching party;

             (b)  (i) by the Buyer if all of the conditions set forth in
       Section 8 shall not have been satisfied on or before the Termination
       Date, other than through failure of the Buyer to fully comply with its
       obligations hereunder, or shall not  have been waived by it on or
       before such dates; or (ii) by the  Seller, if all of the conditions set
                                       63PAGE
<PAGE>
       forth in Section 9 shall  not have been satisfied on or before the
       Termination Date,  other than through failure of the Seller to fully
       comply with  its obligations hereunder, or shall not have been waived
       by  it on or before such dates; or

             (c)  by mutual written consent of the Seller and the Buyer.

       12.2  Effect of Termination.  In the event this Agreement is
   terminated pursuant to Section 12.1, all further obligations of  the
   parties hereunder shall terminate; provided, however, that if  this
   Agreement is so terminated by one party pursuant to  Section 12.1(a) or
   12.1(b)(i) or (ii) because one or more of the  conditions to such party's
   obligations hereunder is not satisfied  as a result of the other party's
   failure to comply with its  obligations under any provision of this
   Agreement, it is  expressly agreed and understood that such party's right
   to pursue  all legal remedies for breach of contract or otherwise,  
   including, without limitation, damages relating thereto, shall  also
   survive such termination unimpaired.  No termination of this  Agreement
   shall act to terminate or otherwise impair the  obligations set forth in
   Sections 13.3, 13.12 and 13.13.

        12.3 Reimbursement of Expenses.  Notwithstanding the foregoing, in the
   event that this Agreement is terminated due to the failure of Seller to
   obtain the Seller's Shareholder Resolution, the Seller shall promptly
   reimburse the Buyer for its costs and expenses reasonably incurred in
   connection with the transactions contemplated hereby up to a maximum of
   500,000 English pounds sterling.

<PAGE>

   including, without limitation, the confidentiality undertaking dated as of
   October 3, 1994, as amended.

       13.8  Assignment.  This Agreement shall not be assigned by the Parent,
   the Buyer or the Seller or by operation of law or  otherwise, except that
   the Buyer may assign some or all of its  rights, interests and/or
   obligations hereunder to one or more  affiliates of the Buyer ("Designated
   Transferees"); provided, however, that any such assignment shall not
   relieve either the Buyer or the Parent of its respective obligations
   hereunder.  If the Buyer  assigns any of its rights, interests and/or
   obligations hereunder  to one or more Designated Transferees, then, unless
   the context  otherwise requires, all references herein to the Buyer shall
   mean  and include the respective Designated Transferees.

   governed by, and construed in accordance with, the laws  of the State of

   matters and issues relating to  the transactions contemplated by this
   Agreement, including but  not limited to, matters and issues of validity,
   construction,  effect, performance and remedies; provided, however, that
   the terms and conditions set forth in Exhibit B and Exhibit D shall be
   governed by the law of England.  Time is of the essence in the  performance
   of this Agreement.

   counterparts, and by the different parties hereto in  separate
   counterparts, each of which when executed shall be  deemed to be an

   efforts to satisfy the conditions to Closing and otherwise  consummate the
   transactions contemplated by this Agreement,  including the execution of
   such documents as may be reasonably  necessary to effectuate the purposes
   of this Agreement.  Without  limiting the generality of the foregoing, the
   Seller shall cause  each Share Seller and Asset Seller to execute such
   documents, and  to take such actions, as may be necessary to enable the
   Seller to  carry out its obligations hereunder and to consummate the  
   transactions contemplated hereby.

<PAGE>
      13.12  Publicity.  Until the business day after the Closing  Date and
   except for any public disclosure which the Buyer or the  Seller in good
   faith believes is required by law or applicable  stock exchange rules,
   neither party shall issue any press release or make any other public
   announcement regarding the transactions contemplated hereby, without the
   prior  written approval of the other party, which shall not be  
   unreasonably withheld.  The parties hereto shall issue a mutually  
   acceptable press release as soon as practicable after the  execution of
   this Agreement and as soon as practicable after the  Closing.

      13.13  Confidential Information.  In connection with the  negotiation of
   this Agreement and the consummation of the  transactions contemplated
   hereby, each party hereto will have  access to data and confidential
   information relating to the other  party.  Each party hereto shall treat
   such data and information  as confidential, preserve the confidentiality
   thereof and not  duplicate or use such data or information, except in
   connection  with the transactions contemplated hereby, and in the event of
    the termination of this Agreement for any reason whatsoever, each  party
   hereto shall return to the other all documents, work papers  and other
   material (including all copies thereof) obtained in  connection with the
   transactions contemplated hereby and will use  reasonable efforts,
   including instructing its employees who have  had access to such
   information, to keep confidential and not to  use any such data or
   information; provided, however, that such  obligations shall not apply to
   any data and information (i) which,  at the time of disclosure, is
   available publicly, (ii) which,  after disclosure, becomes available
   publicly through no fault of the receiving party, (iii) which the receiving
   party knew or to  which the receiving party had access (without violating
   any right of the disclosing party) prior to disclosure by the  disclosing
   party, (iv) which is required by law, regulation or stock exchange rule, or
   in connection with legal process, to be  disclosed, or (v) which is
   disclosed by a receiving party to its  attorneys or accountants, who shall
   respect the above  restrictions.

      13.14  Submission to Jurisdiction and Venue.  Any legal suit, action, or
   proceeding arising out of or relating in any way to this Agreement, any
   other agreement or instrument contemplated herein or the transactions
   contemplated hereby, including but not limited to actions seeking specific
   performance of the terms of this Agreement, actions for indemnity, actions
   seeking declaratory relief regarding the terms of this Agreement or actions
   for breach of this Agreement, shall be institute exclusively in the United
   States District Court for the Southern District of New York, United States
   of America (the "Southern District Court"), or if such court shall not have
   subject matter jurisdiction over such action, a court of general
   jurisdiction of the State of New York located in the City of New York,
   Borough of Manhattan (a "New York Court").  Each party hereby waives any
   objection whatsoever that it may have now or hereafter to the laying of the
   venue of any such suit, action or proceeding exclusively in the Southern
   District Court or a New York Court, as the case may be, and irrevocably
   submits to the exclusive jurisdiction of the Southern District Court in any
   such suit, action or proceeding or, if such court shall not have subject
   matter jurisdiction over such action, the New York Courts.  In the event
                                       67PAGE
<PAGE>
   that any legal suit, action or proceeding of any kind is commenced in or
   brought in any court other than in the Southern District Court (or, if the
   Southern District Court shall not have subject matter jurisdiction over
   such action, a New York Court), the parties agree to, and shall cause their
   respective Subsidiaries and Affiliates that they control to, transfer
   and/or remove any such legal suit, action or proceeding to the Southern
   District Court (or, if the Southern District Court shall not have subject
   matter jurisdiction over such action, a New York Court), or to immediately
   dismiss without prejudice such legal suit, action or proceeding.  Each of
   the Seller and the Buyer hereby designates CT Corporation System (the
   "Agent") as its authorized agent to accept and acknowledge on its behalf
   service of any and all process that may be served in any such suit, action
   or proceeding in any such court.  Each of the Seller and the Buyer agrees
   that service of process upon the Agent at its office at 1633 Broadway, New
   York, New York 10009 (or at such other address in New York County, New York
   as such agent may designate by written notice to the parties) and written
   notice of said service air mailed or delivered to a party hereto at the
   address for notice established pursuant to Section 13.2 shall be deemed in
   every respect effective service of process upon such party in any such
   suit, action or proceeding and shall be taken and held to be valid personal
   service upon such party whether or not such party shall then be doing, or
   at any time shall have done, business within the State of New York, and
   that any such service of process shall be of the same force and validity as
   if service were made upon such party according to the laws governing the
   validity and requirements of such service in such State, and waives all
   claim of error by reason of any such service.  Nothing in this Section
   13.14, however, shall affect the right of either party to serve legal
   process in any other manner permitted by law.

      13.15  Construction.  The language used in this Agreement shall be
   deemed to be the language chosen by the parties hereto  to express their
   mutual intent, and no rule of strict  construction shall be applied against
   either party.  Any  reference to any federal, state, local or foreign
   statute or law shall be deemed also to refer to all rules and regulations  
   promulgated thereunder, unless the context requires otherwise.

                    MASTER GUARANTEE REIMBURSEMENT AGREEMENT


        This AGREEMENT is entered into as of the 1st day of January, 1994 by
   and among Thermo Electron Corporation (the "Parent") and those of its
   subsidiaries that join in this Agreement by executing the signature page
   hereto (the "Majority Owned Subsidiaries").

                                   WITNESSETH:

        WHEREAS, the Majority Owned Subsidiaries in the past have entered
   into, and wish to enter into in the future, various financial transactions,
   such as convertible or nonconvertible debt, bank loans, and equity
   offerings, and other contractual arrangements with third parties (the
   "Underlying Obligations"); 

        WHEREAS, the Majority Owned Subsidiaries acknowledge that they are
   unable to enter into many kinds of Underlying Obligations without a
   guarantee of their performance thereunder from the Parent (a "Parent
   Guarantee");

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

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

        WHEREAS, the Parent is willing to consider continuing to issue Parent
   Guarantees, 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, after the date hereof, 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 under such Underlying Obligation shall
        indemnify and save harmless the Parent from any liability, cost,
        expense or damage (including reasonable attorneys' fees) suffered by
        the Parent as a result of the Parent Guarantee.  If the Underlying
        Obligation is issued by a Second Tier Majority Owned Subsidiary, and
        such Second Tier Majority Owned Subsidiary is unable to fully
        indemnify the Parent (because of the poor financial condition of such
        Second Tier Majority Owned Subsidiary, or for any other reason), then
        the First Tier Majority Owned Subsidiary that owns the majority of the
        stock of such Second Tier Majority Owned Subsidiary shall indemnify
        and save harmless the Parent from any remaining liability, cost,
        expense or damage (including reasonable attorneys' fees) suffered by
        the Parent as a result of the Parent Guarantee.

   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
PAGE
<PAGE>
        Majority Owned Subsidiary.  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 and (b)
        responsibility of the Parent by operation of law for the acts and
        omissions of the Majority Owned Subsidiary, 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 under
        the relevant Underlying Obligation.  Such Majority Owned Subsidiary(s)
        shall have the right, at its own expense, to contest the claim of such
        beneficiary.  If a Majority Owned Subsidiary is contesting the claim
        of such beneficiary, the Parent will not perform under the relevant
        Parent Guarantee unless and until, in the Parent's reasonable
        judgment, the Parent is obligated under the terms of such Parent
        Guarantee to perform.  Subject to the foregoing, any dispute between a
        Majority Owned Subsidiary and a beneficiary of a Parent Guarantee
        shall not affect such Majority Owned Subsidiary's obligation to
        promptly indemnify the Parent hereunder.

   4.   All payments required to be made by a Majority Owned Subsidiary shall
        be made within two days after receipt of notice from the Parent.

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

                                                              Exhibit 10.17

                          THERMO INSTRUMENT SYSTEMS INC.

                           DIRECTORS STOCK OPTION PLAN

             As amended and restated effective as of January 1, 1995

   1.   Purpose

        The purpose of this Directors Stock Option Plan (the "Plan") of Thermo
   Instrument Systems Inc. (the "Company") is to encourage ownership in the
   Company by outside directors of the Company whose services are considered
   essential to the Company's growth and progress and to provide them with a
   further incentive to become directors and to continue as directors of the
   Company.  The Plan is intended to be a nonstatutory stock option plan.

   2.   Administration

        The Board of Directors, or a Committee (the "Committee") consisting of
   two or more directors of the Company appointed by the Board of Directors,
   shall supervise and administer the Plan.  Grants of stock options under the
   Plan and the amount and nature of the options to be granted shall be
   automatic in accordance with Section 5.  However, all questions of
   interpretation of the Plan or of any stock options granted under it shall
   be determined by the Board of Directors or the Committee and such
   determination shall be final and binding upon all persons having an
   interest in the Plan.

   3.   Participation in the Plan

        Directors of the Company who are not employees of the Company or any
   subsidiary or parent of the Company shall be eligible to participate in the
   Plan.  Directors who receive grants of stock options in accordance with
   this Plan are sometimes referred to herein as "Optionees."  

   4.   Stock Subject to the Plan

        The maximum number of shares that may be issued under the Plan shall
   be seventy-five thousand (75,000) shares of the Company's $.10 par value
   Common Stock (the "Common Stock"), and twenty-five thousand (25,000) shares
   of the common stock of each Spinout Subsidiary (as defined in Section 5(B))
   as of the date of the Annual Meeting of Stockholders on which options to
   purchase such common stock are first granted to eligible Directors as
   provided in Section 5(B), each subject to adjustment as provided in Section
   9.  Shares to be issued upon the exercise of options granted under the Plan
   may be either authorized but unissued shares or shares held by the Company
   in its treasury.  If any option expires or terminates for any reason
   without having been exercised in full, the unpurchased shares subject
   thereto shall again be available for options thereafter to be granted. 

   5.   Terms and Conditions

        A.   Annual Stock Option Grants

        Each Director of the Company who meets the requirements of Section 3
   and who is holding office immediately following the Annual Meeting of
PAGE
<PAGE>
   Stockholders, commencing with the Annual Meeting of Stockholders held in
   calendar year 1995, shall be granted an option to purchase 1,000 shares of
   Company common stock at the close of business on the date of such Annual
   Meeting.  Options granted under this Subsection B shall be exercisable as
   to 100% of the shares subject to the option as set forth in Section
   5(C)(1), but shares acquired upon exercise are subject to repurchase by the
   Company at the exercise price in the event that the Optionee ceases to
   serve as a director of the Company, Thermo Electron Corporation ("Thermo
   Electron") or any subsidiary of Thermo Electron, prior to the first
   anniversary of the grant date, for any reason other than death.

        B.   Subsidiary Stock Option Grants.

        Each Director of the Company who meets the requirements of Section 3
   and this Section 5(B), from time to time in accordance with this Section
   5(B), shall be granted an option to purchase shares of the common stock of
   each majority-owned subsidiary of the Company, the common stock of which
   shall have become publicly traded or a portion of which shall have been
   sold primarily to third parties in a private placement or other arms-length
   transaction (such transaction being referred to herein as a "Spinout
   Transaction", and such subsidiary being referred to herein as a "Spinout
   Subsidiary"), upon the following terms and conditions.

        Each eligible Director who is not a Director of the Spinout Subsidiary
   shall be granted an option to purchase 1,500 shares of common stock of the
   Spinout Subsidiary as of the close of business on the date of the Company's
   Annual Meeting of Stockholders that first occurs after the Spinout
   Transaction, and also as of the close of business on the date of every
   fifth Annual Meeting of Stockholders of the Company that occurs thereafter
   during the duration of this Plan.   

        Options granted under this Section 5(B) shall vest and be exercisable
   as to 100% of the shares of common stock subject to the option on the
   fourth anniversary of the grant date of the option, unless, prior to such
   anniversary, the underlying common stock shall have been registered under
   Section 12 of the Securities and Exchange Act of 1934, as amended (referred
   to herein as "Section 12 Registration").  From and after 90 days after the
   effective date of Section 12 Registration, options granted hereunder shall
   be immediately exercisable as to 100% of the shares subject to the option,
   subject to the right of the Company to repurchase the shares at the
   exercise price in the event the Optionee ceases to serve as a director of
   the Company, or any subsidiary of the Company or Thermo Election during the
   option term.  The right of the Company to so repurchase the shares shall
   lapse as to one-fourth of the shares granted on each of the first, second,
   third and fourth anniversaries of the grant date of the option, provided
   the Optionee has remained continuously a director of the Company, Thermo
   Electron or any subsidiary of Thermo Electron since the grant date.  In all
   other respects, the option shall be subject to the general terms and
   conditions applicable to all option grants as set forth below in Section
   5(C), including the determination of the exercise price of such option.

        No Director, who is otherwise eligible under Section 3, shall be
   eligible under this Section 5(B) to receive grants of stock options in
   Spinout Subsidiaries, if such Director also serves as a director of such
   Spinout Subsidiary.

        In the event any subsidiary shall become a "Spinout Subsidiary" as
   defined herein, then there shall be immediately reserved for transfer
PAGE
<PAGE>
   hereunder, on the date options to purchase common stock of the Spinout
   Subsidiary are first granted to eligible Directors and without further
   action required by the Board of Directors or Stockholders of the Company,
   twenty-five thousand (25,000) shares of the common stock of such Spinout
   Subsidiary.

        C.   General Terms and Conditions Applicable to All Grants.

        1.   Except as otherwise provided in Section 5(B), options shall be
             exercisable at any time from and after the six-month anniversary
             of the grant date and prior to the date which is the earliest of:

             (a)  three years after the grant date for options granted under
             Section 5(A) and five years after the grant date for options
             granted under Section 5(B),  (b)  three months after the later of
             the date (i) the Optionee either ceases to meet the requirements
             of Section 3 or (ii) otherwise ceases to serve as a director of
             the Company, Thermo Electron or any subsidiary of Thermo Electron
             (six months in the event the Optionee ceases to meet the
             requirements of this Subsection by reason of his death), or (c)  
             the date of dissolution or liquidation of the Company.

        2.   The exercise price at which Options are granted hereunder shall
             be the average of the closing prices reported by the national
             securities exchange on which the common stock is principally
             traded for the five trading days immediately preceding and
             including the date the option is granted or, if such security is
             not traded on an exchange, the average last reported sale price
             for the five-day period on the NASDAQ National Market List, or
             the average of the closing bid prices for the five-day period
             last quoted by an established quotation service for
             over-the-counter securities, or if none of the above shall apply,
             the last price paid for shares of the Common Stock by independent
             investors in a private placement; provided, however, that such
             exercise price per share shall not be lower than the par value
             per share or less than 50% of the fair market value of the Common
             Stock until such time as the Company elects to be subject to Rule
             16b-3 as amended by SEC Rel. No. 33-28869.

        3.   All options shall be evidenced by a written agreement
             substantially in such form as shall be approved by the Board of
             Directors or Committee, containing terms and conditions
             consistent with the provisions of this Plan.

   6.   Exercise of Options

        A.   Exercise/Consideration

        An option may be exercised in accordance with its terms by written
   notice of intent to exercise the option, specifying the number of shares of
   stock with respect to which the option is then being exercised.  The notice
   shall be accompanied by payment in the form of cash or shares of  common
   stock of the Company (as to options to purchase Company Common Stock) or
   the Spinout Subsidiary (as to options to purchase common stock of the
   Spinout Subsidiary, but only if the common stock is then publicly traded)
   (the shares so tendered referred to herein as "Tendered Shares") with a
   then current market value equal to the exercise price of the shares to be
   purchased; provided, however, that such Tendered Shares shall have been
PAGE
<PAGE>
   acquired by the Optionee more than six months prior to the date of exercise
   (unless such requirement is waived in writing by the Company).  Against
   such payment the Company shall deliver or cause to be delivered to the
   Optionee a certificate for the number of shares then being purchased,
   registered in the name of the Optionee or other person exercising the
   option.  If any law or applicable regulation of the Securities and Exchange
   Commission or other body having jurisdiction in the premises shall require
   the Company or the Director to take any action in connection with shares
   being purchased upon exercise of the option, exercise of the option and
   delivery of the certificate or certificates for such shares shall be
   postponed until completion of the necessary action, which shall be taken at
   the Company's expense.

        B.   Tax Withholding

        The Company shall have the right to deduct from payments of any kind
   otherwise due to the Optionee any federal, state or local taxes of any kind
   required by law to be withheld with respect to any shares issued upon
   exercise of options under the Plan.  Subject to the prior approval of the
   Company, which may be withheld by the Company in its sole discretion, the
   Optionee may elect to satisfy such obligations, in whole or in part, (i) by
   causing the Company to withhold shares of Common Stock otherwise issuable
   pursuant to the exercise of an option or (ii) by delivering to the Company
   shares of Common Stock already owned by the Optionee.  The shares so
   delivered or withheld shall have a fair market value equal to such
   withholding obligation.  The fair market value of the shares used to
   satisfy such withholding obligation shall be determined by the Company as
   of the date that the amount of tax to be withheld is to be determined.
   Notwithstanding the foregoing, no election to use shares for the payment of
   withholding taxes shall be effective unless made in compliance with any
   applicable requirements of Rule 16b-3.

   7.   Transferability

        Options shall not be transferable, otherwise than by will or the laws
   of descent and distribution or pursuant to a qualified domestic relations
   order as defined in the Internal Revenue Code or Title I of the Employee
   Retirement Income Security Act, or the rules thereunder (a "Qualified
   Domestic Relations Order").  Options may be exercised during the life of
   the Optionee only by the Optionee or a transferee pursuant to a Qualified
   Domestic Relations Order.

   8.   Limitation of Rights to Continue as a Director

        Neither the Plan, nor the quantity of shares subject to options
   granted under the Plan, nor any other action taken pursuant to the Plan,
   shall constitute or be evidence of any agreement or understanding, express
   or implied, that the Company will retain a Director for any period of time,
   or at any particular rate of compensation.

   9.   Changes in Common Stock

        If the outstanding shares of Common Stock are increased, decreased or
   exchanged for a different number or kind of shares or other securities, or
   if additional shares or new or different shares or other securities are
   distributed with respect to such shares of Common Stock or other
   securities, through merger, consolidation, sale of all or substantially all
   of the assets of the Company, reorganization, recapitalization,
PAGE
<PAGE>
   reclassification, stock dividend, stock split, reverse stock split or other
   distribution with respect to such shares of Common Stock, or other
   securities, an appropriate proportionate adjustment may be made in the
   maximum number or kind of shares reserved for issuance under the Plan.  No
   fractional shares will be issued under the Plan on account of any such
   adjustments.

   10.  Limitation of Rights in Option Stock

        The Optionees shall have no rights as stockholders in respect of
   shares as to which their options shall not have been exercised,
   certificates issued and delivered and payment as herein provided made in
   full, and shall have no rights with respect to such shares not expressly
   conferred by this Plan or the written agreement evidencing options granted
   hereunder.

   11.  Stock Reserved

        The Company shall at all times during the term of the options reserve
   and keep available such number of shares of the Common Stock as will be
   sufficient to permit the exercise in full of all options granted under this
   Plan and shall pay all other fees and expenses necessarily incurred by the
   Company in connection therewith.

   12.  Securities Laws Restrictions

        A.   Investment Representations.

        The Company may require any person to whom an option is granted, as a
   condition of exercising such option, to give written assurances in
   substance and form satisfactory to the Company to the effect that such
   person is acquiring the Common Stock subject to the option for his or her
   own account for investment and not with any present intention of selling or
   otherwise distributing the same, and to such other effects as the Company
   deems necessary or appropriate in order to comply with federal and
   applicable state securities laws.

        B.   Compliance with Securities Laws.

        Each option shall be subject to the requirement that if, at any time,
   counsel to the Company shall determine that the listing, registration or
   qualification of the shares subject to such option upon any securities
   exchange or under any state or federal law, or the consent or approval of
   any governmental or regulatory body, or that the disclosure of non-public
   information or the satisfaction of any other condition is necessary as a
   condition of, or in connection with, the issuance or purchase of shares
   thereunder, such option may not be exercised, in whole or in part, unless
   such listing, registration, qualification, consent or approval, or
   satisfaction of such condition shall have been effected or obtained on
   conditions acceptable to the Board of Directors.  Nothing herein shall be
   deemed to require the Company to apply for or to obtain such listing,
   registration or qualification, or to satisfy such condition.

   13.  Change in Control

        13.1 Impact of Event

        In the event of a "Change in Control" as defined in Section 13.2, the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

        (a) Any stock options awarded under the Plan that were not previously
        exercisable and vested shall become fully exercisable and vested.

        (b) Shares purchased upon the exercise of options subject to
        restrictions and to the extent not fully vested, shall become fully
        vested and all such restrictions shall lapse so that shares issued
        pursuant to such options shall be free of restrictions.

        13.2 Definition of "Change in Control"

        "Change in Control" means any one of the following events:  (i) when,
   any Person is or becomes the beneficial owner (as defined in Section 13(d)
   of the Exchange Act and the Rules and Regulations thereunder), together
   with all Affiliates and Associates (as such terms are used in Rule 12b-2 of
   the General Rules and Regulations of the Exchange Act) of such Person,
   directly or indirectly, of 50% or more of the outstanding Common Stock of
   the Company, or the 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 or Thermo
   Electron, as the case may be, (ii) the failure of the Prior Directors to
   constitute a majority of the Board of the Company or of the Board of
   Directors of Thermo Electron, as the case may be, at any time within two
   years following any Electoral Event, or (iii) any other event that the
   Prior Directors shall determine constitutes an effective change in the
   control of the Company or Thermo Electron.  As used in the preceding
   sentence, the following capitalized terms shall have the respective
   meanings set forth below:

        (a) "Person" shall include any natural person, any entity, any
        "affiliate" of any such natural person or entity as such term is
        defined in Rule 405 under the Securities Act of 1933 and any "group"
        (within the meaning of such term in Rule 13d-5 under the Exchange
        Act);

        (b) "Prior Directors" shall mean the persons sitting on the Company's
        or Thermo Electron's Board of Directors, as the case may be,
        immediately prior to any Electoral Event (or, if there has been no

   14.  Amendment of the Plan

        The provisions of Sections 3 and 5 of the Plan shall not be amended
   more than once every six months, other than to comport with changes in the
   Code, the Employee Retirement Income Security Act of 1974, or the rules
   thereunder.  Subject to the foregoing, the Board of Directors may at any
   time, and from time to time, modify or amend the Plan in any respect,
   except that if at any time the approval of the Stockholders of the Company
   is required as to such modification or amendment under Rule 16b-3, the
   Board of Directors may not effect such modification or amendment without
   such approval.

        The termination or any modification or amendment of the Plan shall
   not, without the consent of an Optionee, affect his or her rights under an
   option previously granted to him or her.  With the consent of the Optionees
   affected, the Board of Directors may amend outstanding option agreements in
   a manner not inconsistent with the Plan.  The Board of Directors shall have
   the right to amend or modify the terms and provisions of the Plan and of
   any outstanding option to the extent necessary to ensure the qualification
   of the Plan under Rule 16b-3.

   15.  Effective Date of the Plan

        The Plan shall become effective when adopted by the Board of
   Directors, but no option granted under the Plan shall become exercisable

   Company.

        Any written notice to the Company required by any of the provisions of
   the Plan shall be addressed to the Secretary of the Company and shall

shall be governed by the laws of the State of Delaware.

                       APPENDIX TO PROSPECTUS RELATING TO
                          1979 LONG-TERM INCENTIVE PLAN
                                   ON FORM S-8



              1979 LONG-TERM INCENTIVE PLAN OF FINNIGAN CORPORATION
                     (as amended through February 11, 1987)

   1. Purpose of the Plan

        The purpose of the 1979 Long-Term Incentive Plan (the "Plan") of
   Finnigan Corporation (the "Company") is to provide an incentive to eligible
   employees and consultants whose present and potential contributions are
   important to the continued success of the Company, to afford them an
   opportunity to acquire a proprietary interest in the Company, and to enable
   the Company to enlist and retain in its employ the best available talent
   for the successful conduct of its business.  It is intended that this
   purpose will be effected through the granting of (a) incentive stock
   rights, (b) stock options, and (c) stock appreciation rights upon surrender
   by a holder of all or a portion of his option rights. It is further
   intended that options granted pursuant to this Plan may be either incentive
   stock options under Section 422A of the Internal Revenue Code of 1986, as
   amended (the "Code") or options which are not incentive stock options
   (herein after called "nonstatutory stock options").

   2.  Eligible Participants

        Option and/or rights may be granted to salaried employees who are
   officers or who are employed by the Company or its subsidiaries and who are
   deemed to have the potential to contribute to the future success of the
   Company.  Options and/or rights may be granted to a director of the Company
   provided that the director is also an officer or salaried employee.
   Options may be granted to consultants to the Company or its subsidiaries.
   The term "subsidiary" as used in the Plan means any corporation (other than
   the Company) in a unbroken chain of corporations beginning with the Company
   if , at the time of the granting of any options hereunder, each of the
   corporations other than the last corporation in the unbroken chain owns
   stock possessing fifty percent (50%) or more of the total combined voting
   power of all classes of stock in one of the other corporations in such
   chain.

   3.  Stock Subject to the Plan

        The shares that may be issued under the Plan shall not exceed in the
   aggregate 1,120,000* Adjusted to give effect to a two-for-one stock split
   in February 1981.  Shares of the Common Stock of the Company, as adjusted
   to give effect to the antidilution provisions contained in Section 10 and
   11 thereof.  Such shares may be authorized and unissued shares or shares
   purchased in the open market by the Company for the Plan.  If an option or
   right for any reason expires or is terminated without having been exercised
   in full, the remaining shares shall become available for the granting of
   options or rights under the Plan.

   *  Adjusted to give effect to a two-for-one stock split in February 1981.

   4.  Awards Under the Plan

        Awards under the Plan may be of three types, namely "incentive stock
   rights," "stock Options," and "stock appreciation rights."  "Incentive
   stock rights" are composed of incentive stock units which give the holder
   the right to receive, without payment of cash to the Company, shares of
   Common Stock, subject to the terms, conditions, and restrictions described
   in Section 7 hereof.  An "Option" is a right to purchase Common Stock of
   the Company at a fair market value as of the date the option is granted.  A
   "stock appreciation right" is a right given to a holder of an option to
   receive, upon surrender of all or a portion of his option, without payment
   to the company, a number of shares of Common Stock of the Company, and/or
   cash, determined pursuant to a formula in lieu of the purchase of shares
   under the related Option.

   5. Administration

        The Plan shall be administered by the Board of Directors or, if
   established by the Board of Directors, by a committee (the "Committee")
   consisting of not less than three persons, all of whom shall be directors
   of the Company, to be appointed by the Company's Board of Directors.  The
   Human Resources Committee of the Company may be designated by the Board of
   Directors to be the administrative committee for the Plan provided its
   members are otherwise eligible to serve as members of the Committee.  No
   member of the Board of Directors who is at the time or for one year prior
   thereto was eligible to receive an option or right under the Plan (or to
   participate in a similar plan of the Company or any subsidiary) shall be a
   member of the Committee.  Committee members shall serve for such term as
   the Board of Directors may in each case determine, and shall be subject to
   removal at any time by the Board of Directors.  Vacancies on the Committee,
   however caused, shall be filled by the Board of Directors.  The Committee
   shall select one of its members as chairman, and shall hold meetings at
   such times and places as it may determine.  A majority of the Committee
   shall constitute quorum, and acts of the Committee approved at a meeting at
   which a quorum is present, or acts approved in writing by all of the
   members of the Committee, shall be valid acts of the Committee.  Subject to
   the general purposes, terms, and conditions of the Plan, and to the
   direction of the Board of Directors, the Committee, if there be one, shall
   have full power to implement and carry out the Plan including, but not
   limited to, the following:  to construe and interpret the Plan; to
   prescribe, amend, and rescind rules and regulations relating to the Plan;
   and to make all other determinations necessary or advisable for the
   administration of the Plan.  Awards shall be made upon approval by the
   Board of Directors, or if the Committee is given general authority to do so
   by the Board of Directors, upon approval by the Committee without review by
   the Board of Directors; provided, however, that awards to any member of the
   Board of Directors must be recommended or approved by the Committee, if
   any, or, if there is no Committee, by the Board of Directors provided that
   a majority of the Board of Directors and a majority of the Directors
   approving such grant are eligible to serve as members of the Committee.  As
   used herein, except in Sections 11 and 18, reference to the Board of
   Directors shall mean such Board or the Committee, whichever is then acting
   with respect to the Plan.

   6.  Duration of the Plan

        The Plan shall remain in effect until all options and rights granted
   under the Plan have been satisfied by the issuance of shares or the payment
                                      B - 2PAGE
<PAGE>
   of cash, or terminated under the terms of the Plan, provided that options
   and rights under the Plan shall not be granted after ten (10) years from
   the effective date of the Plan.  In no event may incentive stock options be
   granted under the Plan later than March 27, 1989, ten (10) years from the
   date the Plan was adopted by the Board of Directors.

   7.  Incentive Stock Rights

        (a)  Incentive Stock Rights

        The Board of Directors, in its discretion, may grant to eligible
   participants incentive stock rights composed of incentive stock units.
   Incentive stock rights shall be evidenced by incentive stock right
   agreements in such form and not inconsistent with the Plan as the Board of
   Directors shall approve from time to time, which agreements shall contain
   in substance the following terms and conditions:

             (i)  Incentive Stock Units.  An incentive stock rights agreement
        shall specify the number of incentive stock units to which it
        pertains.  Each incentive stock unit shall be equivalent to one share
        of Common Stock of the Company.  Each incentive stock unit shall
        entitle the holder to receive, without payment of cash to the Company,
        one share of Common Stock of the Company in consideration for services
        performed for the Company or for its benefit by the person receiving
        the right subject to the lapse of the incentive periods (hereinafter
        defined).

             (ii)  Incentive Period.  The holder of incentive stock rights
        shall be entitled to receive shares of Common Stock of the Company
        only after the lapse of such incentive periods, and in such manner, as
        shall be fixed by the Board of Directors at the time of grant of
        incentive stock rights to an employee.  (Such period or periods so
        fixed is or are herein referred to as an "incentive period".)  To the
        extent the holder of incentive stock rights receives shares of Common
        Stock of the Company on the lapse of an incentive period, and
        equivalent number incentive stock units subject to such rights shall
        be deemed to have been discharged.

             (iii)  Termination of Employment by Reason of Death or
        Disability.  In the event that an employee to whom incentive stock
        rights have been issued under the Plan terminates employment due to
        death or permanent disability (as determined by the Board of
        Directors), each incentive period established pursuant to Subsection
        7(a)(ii) shall lapse on the date of such termination as to the number
        of full incentive stock units determined by multiplying the total
        number of incentive stock units applicable to such incentive period by
        a fraction, the numerator of which shall be the number of full
        calendar months between the date of grant of the incentive stock
        rights and the date of such termination and the denominator of which
        shall be the number of full calendar months between the date of grant
        of the incentive stock rights and the date such incentive period for
        such units would, but for such termination, have lapsed.  Units upon
        which the incentive period does not lapse pursuant to the foregoing
        sentence shall terminate on the termination date of employment.

             (iv)  Termination of Employment for any other Reason.  In the
        event that an employee to whom incentive stock rights have been issued
        under the Plan terminates his employment for any reason (including
                                      B - 3PAGE
<PAGE>
        dismissal by the Company with or without cause), other than death or
        permanent disability, such rights as to which the incentive period has
        not lapsed shall terminate on termination of employment.

             (v)  Leave of Absence, Other.  For Plan purposes, a transfer of
        an employee from the Company to a Subsidiary or vice versa, or from
        one Subsidiary to another, or a leave of absence duly authorized by
        the Company shall not be deemed a termination of employment or a break
        in the incentive period.  In the case of any employee on an approved
        leave of absence, the Board of Directors may make such provision
        respecting continuance of the incentive stock right while on leave
        from the employ of the Company or a Subsidiary as it may deem
        equitable.

             (vi)  Issuance of Shares.  Upon the lapse of an incentive
        period, the Company shall, without transfer or issue tax to the person
        entitled to receive the shares, deliver to such person a certificate
        or certificates for a number of shares of Common Stock of the Company
        equal to the number of incentive stock units as to which an incentive
        period has lapsed.

        (b)  Dividend Equivalents

        The holder of an incentive stock right shall be entitled to receive
   from the Company cash payments at the same time and in the same amounts
   that the holder of record of a number of shares of Common Stock equal to
   the number of incentive stock units covered by such right would be entitled
   to receive as dividends on such Common Stock of the Company.  Such right to
   cash payment on an incentive stock unit shall apply to all dividends the
   record date for which occurs at any time during the period commencing on
   the date the incentive stock unit is granted and ending on the date that
   the holder of such incentive stock unit becomes a shareholder of record
   with respect to such unit as a result of the lapse of an incentive period
   or the date the incentive stock right otherwise terminates, whichever
   occurs first.

   8.  Options

        The Board of Directors, in its discretion, may grant stock options to
   eligible participants and shall determine whether such options shall be
   incentive stock options or nonstatutory stock options.  Each option shall
   be evidenced by a written Stock Option Agreement which shall expressly
   identify the options as incentive stock options or as nonstatutory stock
   options, and be in such form and contain such provisions as the Board or
   the Committee shall from time to time deem appropriate, provided, however,
   that the grant of a nonstatutory stock option pursuant to this Plan shall
   in no way be construed to be an alternative to the right of an employee to
   purchase stock pursuant to any incentive stock option heretofore or
   hereafter granted to an employee pursuant to any stock option plans now in
   existence or hereafter adopted by the Corporation.  Stock Option Agreements
   shall contain the following terms and conditions:

        (a)  Option Price; Number of Shares

        The Option Price, which shall be approved by the Board of Directors
   shall in no event be less than one hundred percent (100%) of the fair
   market value of the Company's stock at the time the option is granted,
   which shall be for purposes of the Plan:  (i) the last sales price per
                                      B - 4PAGE
<PAGE>
   share of stock as reported by NASDAQ (or successor system ) or by the Wall
   Street Journal for the date the option is granted, or if there is no
   trading on such date, then on the last preceding business day on which
   there was trading; (ii) if the stock of the Company is listed on any stock
   exchange, the most recent closing price for such stock as quoted on such
   exchange for the date the option is granted (or if there are no sales for
   such date of grant, then for the last preceding business day on which there
   were sales); or (iii) the fair market value thereof, as determined in any
   other manner adopted in good faith by the Board of Directors which is in
   accordance with the applicable provisions of the Code.

        The Option agreement shall specify the number of shares to which it
   pertains.

        (b)  Waiting Period and Exercise Dates

        At the time an option is granted, the Board of Directors will
   determine the terms and conditions to be satisfied before shares may be
   purchased, including the dates on which shares subject to the option may
   first be purchased.  In no event may an option be exercised for the
   purchase of any shares until the completion of the service period ending on
   the anniversary date of the grant.  (Such period is referred to herein as
   the "waiting period.")  At the time an option is granted, the Board of
   Directors shall fix the period within which it may be exercised which shall
   not be less than one (1) year nor more than ten (10) years from the date of
   grant.  (Such period is referred to herein as the "exercise period.")

        To the extent that an option to purchase shares is not exercised by an
   optionee when it becomes initially exercisable, it shall not expire but
   shall be carried forward and shall be exercisable until the expiration of
   the exercise period.  Partial exercise will be permitted from time to time
   to the extent shares subject to the option may than be purchasable,
   provided that no partial exercise may be for less than 20 full shares of
   Common Stock or its equivalent.

        (c)  Form and Time of Payment

        Stock purchased pursuant to an option agreement shall be paid for in
   full at the time of purchase either (i) in cash or (ii) in the discretion
   of the Board of Directors or the Committee, through the delivery of shares
   of Common Stock of the Company with a value equal to the total option
   price, or (iii) by a combination of the methods described in (i) and (ii).
   Provision for payment by delivery of shares of Common Stock may be made in
   the original option agreement at the time of grant.  Upon receipt of
   payment, the Company shall, without transfer or issue tax to the optionee
   or other person entitled to exercise the option, deliver to the optionee
   (or other person entitle to exercise the option) a certificate or
   certificates for such shares.

        (d)  Effect of Termination of Employment or Death

        In the event that an optionee during his or her lifetime ceases to be
   an employee of the Company or of any Subsidiary for any reason, including
   retirement, any option, including any unexercised portion thereof, which
   was otherwise exercisable on the date of termination of employment, shall
   expire unless exercised within a period of 90 days from the date on which
   the optionee ceased to be an employee, but in no event after the expiration
   of the exercise period; provided, however, that, if the Board of Directors
                                      B - 5PAGE
<PAGE>
   shall determine that an employee shall have been discharged for misconduct
   or unsatisfactory work, such employee shall not hereafter have any rights
   under the Plan or any option that shall have been granted to him or her
   under the Plan.  In the event of the death of an optionee during this
   90-day period, the option shall be exercisable by his or her personal
   representatives, heirs, or legatees for 90 days from the date of death, but
   in no event after the expiration of the exercise period, to the same extent
   that the optionee could have exercised the option if he or she had not
   died.  In the event of the death of an optionee while an employee of the
   Company or any Subsidiary, that portion of the option which had become
   exercisable on the date of death shall be exercisable by his or her
   personal representatives, heirs, or legatees at any time prior to the
   expiration of one (1) year from the date of death of the optionee, but in
   no event after the expiration of the exercise period.  In the event that an
   optionee ceases to be an employee of the Company or of any Subsidiary for
   any reason, including death or retirement, prior to the lapse of the
   waiting period, his or her option shall terminate and be null and void.

        (e)  Leave of Absence

        In the case of any employee on an approved leave of absence, the Board
   of Directors may make such provision respecting continuance of the option
   while on leave from the employ of the Company or a Subsidiary as it may
   deem equitable, except that in no event shall an option be exercised after
   the expiration of the exercise period.

        (f)  Acceleration of Option Period

        The Board of Directors may accelerate the earliest date on which
   outstanding options (or any installments thereof ) are exercisable, but not
   to a date earlier than the expiration of the waiting period.

        (g)  Options granted under the Plan which are intended to be incentive
   stock options under Section 422A of the code shall be subject to the
   following additional terms and conditions:

             (i)  Prior Outstanding Option.  Except to the extent now or
        hereafter permitted by Section 422A of the Code, no incentive stock
        option granted prior to January 1, 1987 shall be exercisable while
        there remains outstanding (within the meaning of Section 422A(c)(7) of
        the Code) any other incentive stock option which was granted at an
        earlier date to the optionee to purchase stock in the Corporation or
        any other corporation which is, on the date of grant of the later
        option, either a "parent corporation" or "subsidiary corporation" of
        the Corporation or a predecessor corporation of any of such
        corporations (as defined in Section 425 of the Internal Revenue Code
        of 1986).

             (ii)  Dollar Limitation.  In the case of an incentive stock
        option granted after January 1, 1982, but before January 1, 1987, the
        aggregate fair market value (determined as of the time the option is
        granted) for which any employee may be granted incentive stock options
        in any calendar year (under all stock option plans of the Corporation
        and its subsidiaries) shall not exceed $100,000 plus any unused limit
        carryover (determined pursuant to Section 422A of the Internal Revenue
        Code, as amended) to such year.  After December 31, 1986, no incentive
        stock option may be granted to any employee which, when aggregated
        with all other incentive stock options granted to such employee by the
                                      B - 6PAGE
<PAGE>
        Corporation or any other corporation which is either a "parent
        corporation" or "subsidiary corporation" of the Corporation, would
        result in shares of common stock having an aggregate fair market value
        (determined for each such share) as of the date of grant of the option
        in excess of  $100,000 becoming first available for purchase upon
        exercise of one or more incentive stock options during any calendar
        year.

             (iii)  10% Shareholder.  If any optionee to whom an incentive
        stock option is to be granted pursuant to the provisions of the Plan
        is, on the date of grant, the owner of stock (as determined under
        Section 425(d) of the Code) possessing more than 10% of the total
        combined voting power of all classes of stock of the Corporation or
        any one of its subsidiaries, then the following special provisions
        shall be applicable to the option granted to such individual:

               (A) The Option price per share of the Common Stock subject to
                    such incentive stock option shall be less than 110% of the
                    fair market value of one share of Common Stock on the date
                    of grant; and
               (B) The option shall not have a term in excess of five (5)
                    years from the date of grant.  Except as modified by the
                    preceding provisions of this Subsection
                    8(g), all the provisions of the Plan shall be applicable
                    to the incentive stock options granted hereunder.

        (h)  Other Provisions

        Each option granted under the Plan may contain such other terms,
   provisions, and conditions not inconsistent with the Plan as may be
   determined by the Board of Directors.

        (i)  Options to Consultants

        Options granted to consultants shall not be subject to paragraphs 8(b)
   and 8(d) of the Plan, but shall have such terms and conditions pertaining
   to waiting period (if any), exercise date, and effect of termination of the
   consulting relationship as the Board of Directors or Committee shall
   determine in each case.

   9.  Stock Appreciation Rights

        The Board of Directors, in its discretion, may grant stock
   appreciation rights to employees who are granted options under the Plan.
   Such rights shall be evidenced by stock appreciation rights agreements in
   such form and not inconsistent with this Plan as the Board of Directors
   shall approve from time to time, which agreements shall contain in
   substance the following terms and conditions:

        (a)  Grant

        Each right shall relate to a specific option granted under the Plan
   and shall be granted to the optionee concurrently with the grant of an
   incentive stock option or at such later time as determined by the Board of
   Directors if the right relates to a nonstatutory stock option.



                                      B - 7PAGE
<PAGE>
        (b)  Exercise

        A stock appreciation right may only be exercised when the fair market
   value of the Common Stock of the Company exceeds the option price of the
   related option.  A right shall entitle an optionee, to the extent he or she
   so designates from time to time, to receive a number of shares, without
   payment to the company, cash, or cash and shares, as elected by the Board
   of Directors as determined under Subsection 9(c).  Such shares and/or cash
   shall be issued or paid in consideration of services performed for the
   Company or for its benefit by the optionee.  Unless otherwise determined by
   the Board of Directors, a right shall be exercisable to no greater extent
   nor upon any more favorable conditions than its related option is
   exercisable under Subsection 8(b).  An optionee wishing to exercise a right
   in accordance with the foregoing shall give written notice of such exercise
   to the Company.  Upon receipt of such notice, the company shall; (i)
   without transfer or issue tax to the optionee or other person entitled to
   exercise the right, deliver to the person exercising the right a
   certificate or certificates for shares; and/or (ii) pay cash.  The date the
   Company receives written notice of an exercise hereunder is referred to
   herein as the exercise date.

        (c)  Number of Shares or Amount of Cash

        The number of shares which shall be issued pursuant to the exercise of
   a right shall be determined by dividing (i) that portion, as elected by the
   optionee, of the total number of shares which the optionee is eligible to
   purchase pursuant to Subsection 9(b) (as adjusted pursuant to Subsection
   8(b) and Section 10 and 11), multiplied by the amount by which the fair
   market value of a share of Common Stock of the Company on the exercise date
   exceeds the option price of the related option; by (ii) the fair market
   value of a share of Common Stock of the Company on the date the optionee
   exercises the stock appreciation right.  In lieu of issuing shares on the
   exercise of a right, the Board of Directors may elect to pay the cash
   equivalent of the fair market value, on the date the optionee exercises the
   stock appreciation right, of any or all the shares which would otherwise be
   issuable.  No fractional shares shall be issued under this Subsection 9(c).
   Instead, the optionee shall be entitled to receive a cash adjustment equal
   to the same fraction of the fair market value per share of Common Stock on
   the date the Board of Directors makes its election.

        (d)  Effect of Exercise

        Shares under an option to which a right is related shall be used not
   more than once to calculate the number of shares or cash to be received
   pursuant to an exercise of such right.  Shares used to calculate the
   benefits under a right will no longer be available for exercise by the
   optionee nor for regrant to other employees under the Plan.

        (e)  Effect of Termination of Employment or Death

        In the event that the recipient of a right ceases to be an employee of
   the Company or of any subsidiary of the Company for any reason, his or her
   right shall be exercisable only to the extent and upon the conditions that
   its related option is exercisable under Subsection 8(d).
        (f)  In the event that a stock appreciation right is granted that
   relates to an incentive stock option, such right shall contain such
   additional or different terms as may be necessary under applicable

                                      B - 8PAGE
<PAGE>
   regulations to preserve treatment of the incentive stock option under
   Section 422A of the Code.

   10. Recapitalization

        In the event that dividends are payable in Common Stock of the Company
   or in the event there are splits, subdivisions, or combinations of shares
   of Common Stock of the Company, the number of shares available under the
   Plan shall be increased or decreased proportionately, as the case may be,
   and the number of shares deliverable upon the exercise thereafter of any
   option or stock appreciation right or upon distribution pursuant to
   incentive stock rights theretofore granted shall be increased or decreased
   proportionately, as the case may be, without change in the aggregate
   purchase price (where applicable).

   11. Reorganization

        In case the Company is merged or consolidated with another corporation
   and the Company is not the surviving corporation, or in case the property
   or stock of the Company is acquired by another corporation, or in case of a
   separation, reorganization, or liquidation of the Company, the Board of
   Directors of the Company, or the board of directors of any corporation
   assuming the obligations of the Company hereunder, shall, as to outstanding
   options, stock appreciation rights, or incentive stock rights, either (a)
   make appropriate provision for the protection of any such outstanding
   options, stock appreciation rights or incentive stock rights by the
   substitution on an equitable basis of appropriate stock of the Company or
   of the merged, consolidated, or otherwise reorganized corporation which
   will be issuable in respect to the shares of Common Stock of the Company,
   provided only that the excess of the aggregate fair market value of the
   shares subject to the options and rights immediately after such
   substitution over the purchase price thereof is not more than the excess of
   the aggregate fair market value of the shares subject to such options and
   rights immediatley before such substitution over the purchase price
   thereof, or (b) upon written notice to the employee, provide that the
   option of right must be exercised within sixty (60) days of the date of
   such notice or it will be terminated.  In any such case, the Board of
   Directors may, in its discretion, advance the lapse of incentive periods,
   waiting periods, and exercise dates.

   12.  Employment Relationship

        Nothing in the Plan or any award made thereunder shall interfere with
   or limit in any way the right of the Company or of any of its Subsidiaries
   to terminate any recipient's employment or consulting relationship at any
   time, nor confer upon any recipient any right to continue in the employ or
   service of the Company or any of its Subsidiaries.

   13. General Restriction

        Each option and right shall be subject to the requirement that, if ,
   at any time, the Board of Directors shall determine, in its discretion,
   that the listing, registration, or qualification of the shares subject to
   such option or right upon any securities exchange or under any state or
   Federal law, or the consent or approval of any government regulatory body,
   is necessary or desirable as a condition of, or in connection with, the
   granting of such option or right or the issue or purchase of shares
   thereunder, such option or right may not be exercised in whole or in part
                                      B - 9PAGE
<PAGE>
   unless such listing registration, qualification, consent, or approval shall
   have been effected or obtained free of any conditions not acceptable to the
   Board of Directors.

   14. Rights as a Shareholder

        The holder of an option or right shall have no rights as a shareholder
   with respect to any shares covered by the option or right until the date of
   issuance of a stock certificate to him or her for such shares.  Except as
   otherwise expressly provided in the Plan, no adjustment shall be made for
   dividends or other rights for which the record date is prior to the date
   such stock certificate is issued.

   15. Nonassignability of Incentive Stock Rights, Options, and Stock
   Appreciation Rights

        No incentive stock right, option, or stock appreciation right shall be
   assignable or transferable by the recipient except by will or by the laws
   of descent and distribution.  During the life of the recipient, the
   incentive stock right, option, or stock appreciation right shall be
   exercisable only by him or her.

   16. Withholding Taxes

        Whenever, under the Plan, shares are to be issued in satisfaction of
   options or rights granted thereunder, the Company shall have the right to
   require the recipient to remit to the Company an amount sufficient to
   satisfy Federal, state, and local withholding tax requirements prior to the
   delivery of any certificate or certificates for such shares.  Whenever,
   under the Plan, payments are to be made in cash, such payment shall be net
   of an amount sufficient to satisfy Federal, state, and local withholding
   tax requirements.

   17. Nonexclusivity of the Plan

        Neither the adoption of the Plan by the Board of Directors, the
   submission of the Plan to the stockholders of the Company for approval, nor
   any provision of the Plan shall be construed as creating any limitations on
   the power of the Board to adopt such additional compensation arrangements
   as it may deem desirable, including, without limitation, the granting of
   stock options otherwise than under the Plan, and such arrangements may be
   either generally applicable or applicable only in specific cases.

   18. Amendment, Suspension, or Termination of the Plan

        The Board of Directors may at any time amend, alter, suspend, or
   discontinue the Plan, but no amendment, alteration, suspension, or
   discontinuation shall be made which would impair the rights of any grantee
   under any grant theretofore made, without his or her consent, or which,
   without the approval of the stockholders, would:

             (a)  Except as is provided in Section 10 and 11 of the Plan,     
                    increase the total number of shares of stock reserved for
                    the purposes of the Plan;
             (b)  Extend the duration of the Plan;
             (c)  Extend the period during and over which options may be      
                    exercised under the Plan; or 

                                     B - 10PAGE
<PAGE>
             (d)  Change the class of persons eligible to participate in the  
                    Plan under Section 2.

        Without limiting the foregoing, the Board of Directors may, at any
   time or from time to time, authorize the Company, with the consent of the
   respective recipients, to issue new options or options in exchange for the
   surrender and cancellation of any or all outstanding options or rights.

   19. Effective Date of the Plan

        The Plan shall become effective upon approval of the Board of
   Directors and by stockholders holding a majority of the shares entitled to
   vote.  Options may be granted and exercised under the Plan only after there
   has been compliance with all applicable Federal and state securities laws.

        The amendments to the Plan adopted by the Board of Directors on
   February 17, 1982, shall become null and void if they are not approved by
   August 13, 1982, by the stockholders of the Corporation holding a majority
   of the shares entitled to vote.  Such amendments, unless otherwise
   provided, are specifically intended to apply to previously granted options
   to the extent necessary to permit such options to qualify for treatment as
   incentive stock options.  Notwithstanding the foregoing, no amendment shall
   apply to any option if such amendment would constitute a modification,
   extension, or renewal of the option under Section 425(h) of the Code, as
   qualified by Section 251(c) of the Economic Recovery Tax Act of 1981.

        The Corporation is authorized to enter into such amending agreements
   with optionees, and to file such elections with the Internal Revenue
   Service, as may be necessary or appropriate to convert previously granted
   options into incentive stock options.

                                                             Exhibit 10.39
                        THERMO ENERGY SYSTEMS CORPORATION

                              EQUITY INCENTIVE PLAN


   1.   Purpose

        The purpose of this Equity Incentive Plan (the "Plan") is to secure
   for Thermo Energy Systems Corporation (the "Company") and its Stockholders
   the benefits arising from capital stock ownership by employees 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 two or more members of the Board, each of whom shall be
   deemed a "disinterested person" within the meaning of Rule 16b-3 (or any
   successor rule) of the Securities Exchange Act of 1934 (the "Exchange
   Act").  

   3.   Effective Date

        The Plan shall be effective as of March 17, 1994, 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.
PAGE
<PAGE>
   4.   Shares Subject to the Plan

        Subject to adjustment as provided in Section 10.6, the total number of
   shares of Common Stock reserved and available for distribution under the
   Plan shall be 400,000 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 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.

        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 422 of the Internal Revenue Code of
   1986, as amended (the "Code"), or options that are not intended to meet the
   requirements of Section 422 ("non-statutory options").
PAGE
<PAGE>
        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 the par 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 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 to buy
   out for a payment in cash, shares of Common Stock, deferred stock or
   restricted stock, an option previously granted, based on such terms and
   conditions as the Board shall establish and communicate to the option
   holder at the time that such offer is made.

        6.1.6     Special Rules for Incentive Stock Options.  Each provision
   of the Plan and each option agreement evidencing an incentive stock option
   shall be construed so that each incentive stock option shall be an
   incentive stock option as defined in Section 422 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 stock options
PAGE
<PAGE>
   may be granted only to employees of the Company and its subsidiaries.  The
   exercise price of an incentive stock 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.

        6.2  Restricted and Unrestricted Stock

        An Award of restricted stock entitles the recipient thereof to acquire
   shares of Common Stock upon payment of the purchase price subject to
   restrictions specified in the instrument evidencing the Award.

        6.2.1     Restricted Stock Awards.  Awards of restricted stock shall
   be evidenced by restricted stock agreements.  Such agreements shall conform
   to the requirements of the Plan, and may contain such other provisions
   (including restriction and forfeiture provisions, change of control,
   protection in the event of mergers, consolidations, dissolutions and
   liquidations) as the Board shall deem advisable.

        6.2.2     Restrictions.  Until the restrictions specified in a
   restricted stock agreement shall lapse, restricted stock may not be sold,
   assigned, transferred, pledged or otherwise encumbered or disposed of, and
   upon certain conditions specified in the restricted stock agreement, must
   be resold to the Company for the price, if any, specified in such
   agreement.  The restrictions shall lapse at such time or times, and on such
   conditions, as the Board may specify.  The Board may at any time accelerate
   the time at which the restrictions on all or any part of the shares shall
   lapse.

        6.2.3     Rights as a Stockholder.  A Participant who acquires shares
   of restricted stock will have all of the rights of a Stockholder with
   respect to such shares including the right to receive dividends and to vote
   such shares.  Unless the Board otherwise determines, certificates
   evidencing shares of restricted stock will remain in the possession of the
   Company until such shares are free of all restrictions under the Plan.

        6.2.4     Purchase Price.  The purchase price of shares of restricted
   stock shall be determined by the Board, in its sole discretion, but such
   price may not be less than the par value of such shares.

        6.2.5     Other Awards Settled With Restricted Stock.  The Board may
   provide that any or all the Common Stock delivered pursuant to an Award
   will be restricted stock.
     
        6.2.6     Unrestricted Stock.  The Board may, in its sole discretion,
   sell to any Participant shares of Common Stock free of restrictions under
   the Plan for a price determined by the Board, but which may not be less
   than the par value per share of the Common Stock.
PAGE
<PAGE>
        6.3  Deferred Stock

        6.3.1     Deferred Stock Award.  A deferred stock Award entitles the
   recipient to receive shares of deferred stock which is Common Stock to be
   delivered in the future.  Delivery of the Common Stock will take place at
   such time or times, and on such conditions, as the Board may specify.  The
   Board may at any time accelerate the time at which delivery of all or any
   part of the Common Stock will take place.

        6.3.2     Other Awards Settled with Deferred Stock.  The Board may, at
   the time any Award described in this Section 6 is granted, provide that, at
   the time Common Stock would otherwise be delivered pursuant to the Award,
   the Participant will instead receive an instrument evidencing the right to
   future delivery of deferred stock.

        6.4  Performance Awards

        6.4.1     Performance Awards.  A performance Award entitles the
   recipient to receive, without payment, an Amount, in cash or Common Stock
   or a combination thereof (such form to be determined by the Board),
   following the attainment of performance goals.  Performance goals may be
   related to personal performance, corporate performance, departmental
   performance or any other category of performance deemed by the Board to be
   important to the success of the Company.  The Board will determine the
   performance goals, the period or periods during which performance is to be
   measured and all other terms and conditions applicable to the Award.

        6.4.2     Other Awards Subject to Performance Conditions.  The Board
   may, at the time any Award described in this Section 6 is granted, impose
   the condition (in addition to any conditions specified or authorized in
   this Section 6 of the Plan) that performance goals be met prior to the
   Participant's realization of any payment or benefit under the Award.

   7.   Purchase Price and Payment

        Except as otherwise provided in the Plan, the purchase price of Common
   Stock to be acquired pursuant to an Award shall be the price determined by
   the Board, provided that such price shall not be less than the par value of
   the Common Stock.   Except as otherwise provided in the Plan, the Board may
   determine the method of payment of the exercise price or purchase price of
   an Award granted under the Plan and the form of payment.  The Board may
   determine that all or any part of the purchase price of 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.
PAGE
<PAGE>
        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
   theparticipant 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 participant's income tax liabilities arising
   from all payments under the Plan.

   9.   Change in Control

        9.1  Impact of Event

        In the event of a "Change in Control" as defined in Section 9.2, the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

        (a) Any stock options or other stock-based Awards awarded under the
        Plan that were not previously exercisable and vested shall become
        fully exercisable and vested.

        (b) Awards of restricted stock and other stock-based Awards subject to
        restrictions and to the extent not fully vested, shall become fully
        vested and all such restrictions shall lapse so that shares issued
        pursuant to such Awards shall be 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.

        9.2  Definition of "Change in Control"

   any Person is or becomes the beneficial owner (as defined in Section 13(d)
   of the Exchange Act and the Rules and Regulations thereunder), together

   the General Rules and Regulations of the Exchange Act) of such Person,
   directly or indirectly, of 50% or more of the outstanding Common Stock of

        Act);

        (b) "Prior Directors" shall mean the persons sitting on the Company's
        or Thermo Electron's Board of Directors, as the case may be,

        Directors on the date of this Agreement) and any future director of
        the Company or Thermo Electron who has been nominated or elected by a

   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.
PAGE
<PAGE>
        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

        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 otherwise specifically provided by the Board in the case of
   participants who are not reporting persons under Section 16 of the Exchange
   Act, 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 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).

        10.6 Adjustments in the Event of Certain Transactions

        (a)  In the event of a stock dividend, stock split or combination of
   shares, recapitalization or other change in the Company's capitalization,
   or other distribution with respect to common Stockholders other than normal
   cash dividends, 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, 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 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.
PAGE
<PAGE>
        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 and its subsidiaries shall not be deemed
   termination of employment.

        10.8 Other Employee Benefits

        The value of an Award granted to a Participant who is an employee, and
   the amount of any compensation deemed to be received by an employee as a
   result of any exercise or purchase of Common Stock pursuant to an Award or
   sale of shares received under the Plan, will not constitute "earnings" or
   "compensation" with respect to which any other employee benefits of such
   employee are determined, including without limitation benefits under any
   pension, stock ownership, stock purchase, life insurance, medical, health,
   disability or salary continuation plan.

        10.9 Legal Holidays

        If any day on or before which action under the Plan must be taken
   falls on a Saturday, Sunday or legal holiday, such action may be taken on
   the next succeeding day not a Saturday, Sunday or legal holiday.

        10.10     Foreign Nationals

        Without amending the Plan, Awards may be granted to persons who are
   foreign nationals or employed outside the United States or both, on such
   terms and conditions different from those specified in the Plan, as may, in
   the judgment of the Board, be necessary or desirable to further the purpose
   of the Plan.

   11.  Termination and Amendment

        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 Exchange Act.  No amendment of the Plan or any agreement
   evidencing Awards under the Plan may adversely affect the rights of any
   participant under any Award previously granted without such participant's    
   consent.

                            THERMO CARDIOSYSTEMS INC.
                              EQUITY INCENTIVE PLAN

   1.   Purpose

        The purpose of this Equity Incentive Plan (the "Plan") is to secure
   for Thermo Cardiosystems Inc. (the "Company") and its Stockholders the
   benefits arising from capital stock ownership by employees 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 two or more members of the Board, each of whom shall be
   deemed a "disinterested person" within the meaning of Rule 16b-3 (or any
   successor rule) of the Securities Exchange Act of 1934 (the "Exchange
   Act").  

   3.   Effective Date

        The Plan shall be effective as of February 28, 1994, subject to the
   approval of the Plan by the Company's Stockholders at the next annual
   meeting of 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.
PAGE
<PAGE>
   4.   Shares Subject to the Plan

        Subject to adjustment as provided in Section 10.6, the total number of
   shares of  Common Stock reserved and available for distribution under the
   Plan shall be 500,000 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 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.

        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").
PAGE
<PAGE>
        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 the par 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 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 to buy
   out for a payment in cash, shares of Common Stock, deferred stock or
   restricted stock, an option previously granted, based on such terms and
   conditions as the Board shall establish and communicate to the option
   holder at the time that such offer is made.

        6.1.6     Special Rules for Incentive Stock Options.  Each provision
   of the Plan and each option agreement evidencing an incentive stock option
   shall be construed so that each incentive stock option shall be an
   incentive stock option as defined in Section 422 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 stock options
PAGE
<PAGE>
   may be granted only to employees of the Company and its subsidiaries.  The
   exercise price of an incentive stock 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.

        6.2  Restricted and Unrestricted Stock

        An Award of restricted stock entitles the recipient thereof to acquire
   shares of Common Stock upon payment of the purchase price subject to
   restrictions specified in the instrument evidencing the Award.

        6.2.1     Restricted Stock Awards.  Awards of restricted stock shall
   be evidenced by restricted stock agreements.  Such agreements shall conform
   to the requirements of the Plan, and may contain such other provisions
   (including restriction and forfeiture provisions, change of control,
   protection in the event of mergers, consolidations, dissolutions and
   liquidations) as the Board shall deem advisable.

        6.2.2     Restrictions.  Until the restrictions specified in a
   restricted stock agreement shall lapse, restricted stock may not be sold,
   assigned, transferred, pledged or otherwise encumbered or disposed of, and
   upon certain conditions specified in the restricted stock agreement, must
   be resold to the Company for the price, if any, specified in such
   agreement.  The restrictions shall lapse at such time or times, and on such
   conditions, as the Board may specify.  The Board may at any time accelerate
   the time at which the restrictions on all or any part of the shares shall
   lapse.

        6.2.3     Rights as a Stockholder.  A Participant who acquires shares
   of restricted stock will have all of the rights of a Stockholder with
   respect to such shares including the right to receive dividends and to vote
   such shares.  Unless the Board otherwise determines, certificates
   evidencing shares of restricted stock will remain in the possession of the
   Company until such shares are free of all restrictions under the Plan.

        6.2.4     Purchase Price.  The purchase price of shares of restricted
   stock shall be determined by the Board, in its sole discretion, but such
   price may not be less than the par value of such shares.

        6.2.5     Other Awards Settled With Restricted Stock.  The Board may
   provide that any or all the Common Stock delivered pursuant to an Award
   will be restricted stock.
     
        6.2.6     Unrestricted Stock.  The Board may, in its sole discretion,
   sell to any Participant shares of Common Stock free of restrictions under
   the Plan for a price determined by the Board, but which may not be less
   than the par value per share of the Common Stock.
PAGE
<PAGE>
        6.3  Deferred Stock

        6.3.1     Deferred Stock Award.  A deferred stock Award entitles the
   recipient to receive shares of deferred stock which is Common Stock to be
   delivered in the future.  Delivery of the Common Stock will take place at
   such time or times, and on such conditions, as the Board may specify.  The
   Board may at any time accelerate the time at which delivery of all or any
   part of the Common Stock will take place.

        6.3.2     Other Awards Settled with Deferred Stock.  The Board may, at
   the time any Award described in this Section 6 is granted, provide that, at
   the time Common Stock would otherwise be delivered pursuant to the Award,
   the Participant will instead receive an instrument evidencing the right to
   future delivery of deferred stock.

        6.4  Performance Awards

        6.4.1     Performance Awards.  A performance Award entitles the
   recipient to receive, without payment, an Amount, in cash or Common Stock
   or a combination thereof (such form to be determined by the Board),
   following the attainment of performance goals.  Performance goals may be
   related to personal performance, corporate performance, departmental
   performance or any other category of performance deemed by the Board to be
   important to the success of the Company.  The Board will determine the
   performance goals, the period or periods during which performance is to be
   measured and all other terms and conditions applicable to the Award.

        6.4.2     Other Awards Subject to Performance Conditions.  The Board
   may, at the time any Award described in this Section 6 is granted, impose
   the condition (in addition to any conditions specified or authorized in
   this Section 6 of the Plan) that performance goals be met prior to the
   Participant's realization of any payment or benefit under the Award.

   7.   Purchase Price and Payment

        Except as otherwise provided in the Plan, the purchase price of Common
   Stock to be acquired pursuant to an Award shall be the price determined by
   the Board, provided that such price shall not be less than the par value of
   the Common Stock.   Except as otherwise provided in the Plan, the Board may
   determine the method of payment of the exercise price or purchase price of
   an Award granted under the Plan and the form of payment.  The Board may
   determine that all or any part of the purchase price of 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.
PAGE
<PAGE>
        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 participant's income tax liabilities arising from all
   payments under the Plan.

   9.   Change in Control

        9.1  Impact of Event

        In the event of a "Change in Control" as defined in Section 9.2, the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

        (a) Any stock options or other stock-based Awards awarded under the
   Plan that were not previously exercisable and vested shall become fully
   exercisable and vested.

        (b) Awards of restricted stock and other stock-based Awards subject to
   restrictions and to the extent not fully vested, shall become fully vested
   and all such restrictions shall lapse so that shares issued pursuant to
   such Awards shall be 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.

   sentence, the following capitalized terms shall have the respective

        (b) "Prior Directors" shall mean the persons sitting on the Company's
   or Thermo Electron's Board of Directors, as the case may be, immediately

   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
PAGE
<PAGE>
   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

        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 otherwise specifically provided by the Board in the case of
   participants who are not reporting persons under Section 16 of the Exchange
   Act, 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 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).

        10.6 Adjustments in the Event of Certain Transactions

        (a)  In the event of a stock dividend, stock split or combination of
   shares, recapitalization or other change in the Company's capitalization,
   or other distribution with respect to common Stockholders other than normal
   cash dividends, 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, 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 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.
PAGE
<PAGE>
        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 and its subsidiaries shall not be deemed
   termination of employment.

        10.8 Other Employee Benefits

        The value of an Award granted to a Participant who is an employee, and
   the amount of any compensation deemed to be received by an employee as a
   result of any exercise or purchase of Common Stock pursuant to an Award or
   sale of shares received under the Plan, will not constitute "earnings" or
   "compensation" with respect to which any other employee benefits of such
   employee are determined, including without limitation benefits under any
   pension, stock ownership, stock purchase, life insurance, medical, health,
   disability or salary continuation plan.

        10.9 Legal Holidays

        If any day on or before which action under the Plan must be taken
   falls on a Saturday, Sunday or legal holiday, such action may be taken on
   the next succeeding day not a Saturday, Sunday or legal holiday.

        10.10     Foreign Nationals

        Without amending the Plan, Awards may be granted to persons who are
   foreign nationals or employed outside the United States or both, on such
   terms and conditions different from those specified in the Plan, as may, in
   the judgment of the Board, be necessary or desirable to further the purpose
   of the Plan.

   11.  Termination and Amendment

        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 Exchange Act.  No amendment of the Plan or any agreement
   evidencing Awards under the Plan may adversely affect the rights of any
   participant under any Award previously granted without such participant's
   consent.

                               THERMO VOLTEK CORP.
                              EQUITY INCENTIVE PLAN

   1.   Purpose

        The purpose of this Equity Incentive Plan (the "Plan") is to secure
   for Thermo Voltek Corp. (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 two or more members of the Board, each of whom shall be
   deemed a "disinterested person" within the meaning of Rule 16b-3 (or any
   successor rule) of the Securities Exchange Act of 1934 (the "Exchange
   Act").  

   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.
PAGE
<PAGE>
   4.   Shares Subject to the Plan

        Subject to adjustment as provided in Section 10.6, the total number of
   shares of the common stock, $.05 par value per share, of the Company (the
   "Common Stock"), reserved and available for distribution under the Plan
   shall be 200,000 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.

        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").
PAGE
<PAGE>
        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 the par 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 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 to buy
   out for a payment in cash, shares of Common Stock, deferred stock or
   restricted stock, an option previously granted, based on such terms and
   conditions as the Board shall establish and communicate to the option
   holder at the time that such offer is made.

        6.1.6     Special Rules for Incentive Stock Options.  Each provision
   of the Plan and each option agreement evidencing an 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 stock options
PAGE
<PAGE>
   may be granted only to employees of the Company and its subsidiaries.  The
   exercise price of an incentive stock 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.

        6.2  Restricted and Unrestricted Stock

        An Award of restricted stock entitles the recipient thereof to acquire
   shares of Common Stock upon payment of the purchase price subject to
   restrictions specified in the instrument evidencing the Award.

        6.2.1     Restricted Stock Awards.  Awards of restricted stock shall
   be evidenced by restricted stock agreements.  Such agreements shall conform
   to the requirements of the Plan, and may contain such other provisions
   (including restriction and forfeiture provisions, change of control,
   protection in the event of mergers, consolidations, dissolutions and
   liquidations) as the Board shall deem advisable.

        6.2.2     Restrictions.  Until the restrictions specified in a
   restricted stock agreement shall lapse, restricted stock may not be sold,
   assigned, transferred, pledged or otherwise encumbered or disposed of, and
   upon certain conditions specified in the restricted stock agreement, must
   be resold to the Company for the price, if any, specified in such
   agreement.  The restrictions shall lapse at such time or times, and on such
   conditions, as the Board may specify.  The Board may at any time accelerate
   the time at which the restrictions on all or any part of the shares shall
   lapse.

        6.2.3     Rights as a Stockholder.  A Participant who acquires shares
   of restricted stock will have all of the rights of a Stockholder with
   respect to such shares including the right to receive dividends and to vote
   such shares.  Unless the Board otherwise determines, certificates
   evidencing shares of restricted stock will remain in the possession of the
   Company until such shares are free of all restrictions under the Plan.

        6.2.4     Purchase Price.  The purchase price of shares of restricted
   stock shall be determined by the Board, in its sole discretion, but such
   price may not be less than the par value of such shares.

        6.2.5     Other Awards Settled With Restricted Stock.  The Board may
   provide that any or all the Common Stock delivered pursuant to an Award
   will be restricted stock.
     
        6.2.6     Unrestricted Stock.  The Board may, in its sole discretion,
   sell to any Participant shares of Common Stock free of restrictions under
   the Plan for a price determined by the Board, but which may not be less
   than the par value per share of the Common Stock.
PAGE
<PAGE>
        6.3  Deferred Stock

        6.3.1     Deferred Stock Award.  A deferred stock Award entitles the
   recipient to receive shares of deferred stock which is Common Stock to be
   delivered in the future.  Delivery of the Common Stock will take place at
   such time or times, and on such conditions, as the Board may specify.  The
   Board may at any time accelerate the time at which delivery of all or any
   part of the Common Stock will take place.

        6.3.2     Other Awards Settled with Deferred Stock.  The Board may, at
   the time any Award described in this Section 6 is granted, provide that, at
   the time Common Stock would otherwise be delivered pursuant to the Award,
   the Participant will instead receive an instrument evidencing the right to
   future delivery of deferred stock.

        6.4  Performance Awards

        6.4.1     Performance Awards.  A performance Award entitles the
   recipient to receive, without payment, an Amount, in cash or Common Stock
   or a combination thereof (such form to be determined by the Board),
   following the attainment of performance goals.  Performance goals may be
   related to personal performance, corporate performance, departmental
   performance or any other category of performance deemed by the Board to be
   important to the success of the Company.  The Board will determine the
   performance goals, the period or periods during which performance is to be
   measured and all other terms and conditions applicable to the Award.

        6.4.2     Other Awards Subject to Performance Conditions.  The Board
   may, at the time any Award described in this Section 6 is granted, impose
   the condition (in addition to any conditions specified or authorized in
   this Section 6 of the Plan) that performance goals be met prior to the
   Participant's realization of any payment or benefit under the Award.

   7.   Purchase Price and Payment

        Except as otherwise provided in the Plan, the purchase price of Common
   Stock to be acquired pursuant to an Award shall be the price determined by
   the Board, provided that such price shall not be less than the par value of
   the Common Stock.   Except as otherwise provided in the Plan, the Board may
   determine the method of payment of the exercise price or purchase price of
   an Award granted under the Plan and the form of payment.  The Board may
   determine that all or any part of the purchase price of 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.
PAGE
<PAGE>
        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 participant's income tax liabilities arising from all
   payments under the Plan.

   9.   Change in Control

        9.1  Impact of Event

        In the event of a "Change in Control" as defined in Section 9.2, the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

        (a) Any stock options or other stock-based Awards awarded under the
        Plan that were not previously exercisable and vested shall become
        fully exercisable and vested.

        (b) Awards of restricted stock and other stock-based Awards subject to
        restrictions and to the extent not fully vested, shall become fully
        vested and all such restrictions shall lapse so that shares issued
        pursuant to such Awards shall be 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.

        9.2  Definition of "Change in Control"

        "Change in Control" means any one of the following events:  (i) when,
   any Person is or becomes the beneficial owner (as defined in Section 13(d)
   of the Exchange Act and the Rules and Regulations thereunder), together
   with all Affiliates and Associates (as such terms are used in Rule 12b-2 of
   the General Rules and Regulations of the Exchange Act) of such Person,
   directly or indirectly, of 50% or more of the outstanding Common Stock of
   the Company or its parent corporation, Thermedics Inc. ("Thermedics"), or
   the 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 applicable issuer, (ii) the failure of the
   Prior Directors to constitute a majority of the Board of Directors of the
   Company, Thermedics or Thermo Electron, as the case may be, at any time
   within two years following any Electoral Event, or (iii) any other event
   that the Prior Directors shall determine constitutes an effective change in
   the control of the Company, Thermedics or Thermo Electron.  As used in the
   preceding sentence, the following capitalized terms shall have the
   respective meanings set forth below:

        (a) "Person" shall include any natural person, any entity, any
        "affiliate" of any such natural person or entity as such term is
        defined in Rule 405 under the Securities Act of 1933 and any "group"
PAGE
<PAGE>
        (within the meaning of such term in Rule 13d-5 under the Exchange
        Act);

        (b) "Prior Directors" shall mean the persons sitting on the Company's,
        Thermedics' or Thermo Electron's Board of Directors, as the case may
        be, immediately prior to any Electoral Event (or, if there has been no
        Electoral Event, those persons sitting on the applicable Board of
        Directors on the date of this Agreement) and any future director of
        the Company, Thermedics or Thermo Electron who has been nominated or
        elected by a majority of the Prior Directors who are then members of
        the Board of Directors of the Company, Thermedics or Thermo Electron,
        as the case may be; and 

        (c) "Electoral Event" shall mean any contested election of Directors,
        or any tender or exchange offer for the Company's, Thermedics' or
        Thermo Electron's Common Stock, not approved by the Prior Directors,
        by any Person other than the Company, Thermedics, Thermo Electron or a
        majority-owned subsidiary of Thermo Electron.

   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
PAGE
<PAGE>
   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

        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 otherwise specifically provided by the Board in the case of
   participants who are not reporting persons under Section 16 of the Exchange
   Act, 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 the laws of descent and distribution, except pursuant to the
   terms of a qualified domestic relations order as defined in the Code, 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).

        10.6 Adjustments in the Event of Certain Transactions

        (a)  In the event of a stock dividend, stock split or combination of
   shares, recapitalization or other change in the Company's capitalization,
   or other distribution with respect to common Stockholders other than normal
   cash dividends, 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, 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 adjustments other than those required by law may
PAGE
<PAGE>
   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 and its subsidiaries shall not be deemed
   termination of employment.

        10.8 Other Employee Benefits

        The value of an Award granted to a Participant who is an employee, and
   the amount of any compensation deemed to be received by an employee as a
   result of any exercise or purchase of Common Stock pursuant to an Award or
   sale of shares received under the Plan, will not constitute "earnings" or
   "compensation" with respect to which any other employee benefits of such
   employee are determined, including without limitation benefits under any
   pension, stock ownership, stock purchase, life insurance, medical, health,
   disability or salary continuation plan.

        10.9 Legal Holidays

        If any day on or before which action under the Plan must be taken
   falls on a Saturday, Sunday or legal holiday, such action may be taken on
   the next succeeding day not a Saturday, Sunday or legal holiday.

        10.10     Foreign Nationals

        Without amending the Plan, Awards may be granted to persons who are
   foreign nationals or employed outside the United States or both, on such
   terms and conditions different from those specified in the Plan, as may, in
   the judgment of the Board, be necessary or desirable to further the purpose
   of the Plan.

   11.  Termination and Amendment

        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 Exchange Act.  No amendment of the Plan or any agreement
PAGE
<PAGE>
   evidencing Awards under the Plan may adversely affect the rights of any
   participant under any Award previously granted without such participant's
   consent.

                                                               Exhibit 10.51
                         THERMO INSTRUMENT SYSTEMS INC.
                  THERMOSPECTRA NONQUALIFIED STOCK OPTION PLAN

   1.   Purpose

        This Nonqualified Stock Option Plan (the "Plan") is intended to
   encourage ownership of Common Stock, $0.01 par value (the "Common Stock"),
   of ThermoSpectra Corporation ("ThermoSpectra"), a subsidiary of Thermo
   Instrument Systems Inc. (the "Company"), by persons selected by the Board
   of Directors (or a committee thereof) in its sole discretion, including
   directors, executive officers, key employees and consultants of the
   Company, its parent corporation and their subsidiaries, and to provide
   additional incentive for them to promote the success of the business of the
   Company and ThermoSpectra.  The Plan is intended to be a nonstatutory stock
   option plan.

   2.   Effective Date of the Plan

        The Plan shall become effective on October 25, 1994.

   3.   Stock Subject to Plan

        At no time shall the number of shares of the Common Stock then
   outstanding which are attributable to the exercise of options granted under
   the Plan plus the number of shares then issuable upon the exercise of
   outstanding options granted under the Plan exceed 200,000 shares, however,
    to the provisions of paragraph 11 of the Plan.  Shares to be issued upon
   the exercise of options granted under the Plan shall be shares of
   ThermoSpectra beneficially owned by the Company.  If any option expires or
   terminates for any reason without having been exercised in full, the
   unpurchased shares subject thereto shall again be available for options
   thereafter to be granted.

   4.   Administration

        The Plan shall be administered by a committee (the "Committee")
   composed of the members of the Board of Directors of the Company, no member
   of which shall act upon any matter exclusively affecting any option granted
   or to be granted to himself or herself under the Plan.  Subject to the
   provisions of the Plan, the Committee shall have complete authority, in its
   discretion, to make the following determinations with respect to each
   option to be granted by the Company:  (a) the person to receive the option
   (the "Optionee"); (b) the time of granting the option; (c) the number of
   shares subject thereto; (d) the option price; (e) the option period; and
   (f) the terms of the option and form of option agreement (which need not be
   identical, but which shall conform to the applicable terms and conditions
   of the Plan and contain such other provisions as the Board of Directors
   deems advisable and not inconsistent with the Plan).  In making such
   determinations, the Committee may take into account the nature of the
   services rendered by the Optionees, their present and potential
   contributions to the success of the Company and/or one or more of its
   subsidiaries, and such other factors as the Committee in its discretion
   shall deem relevant.  Subject to the provisions of the Plan, the Committee
   shall also have complete authority to interpret the Plan, to prescribe,
   amend, and rescind rules and regulations relating to it, to determine the
   terms and provisions of the respective option agreements (which need not be
PAGE
<PAGE>
   identical), and to make all other determinations necessary or advisable for
   the administration of the Plan.  The Committee's determinations on the
   matters referred to in this paragraph 4 shall be conclusive.

   5.   Eligibility

        An option may be granted to any person selected by the Committee in
   its sole discretion.

   6.   Time of Granting Options

        The granting of an option shall take place at the time specified by
   the Committee.  Only if expressly so provided by the Committee shall the
   granting of an option be regarded as taking place at the time when a
   written option agreement shall have been duly executed and delivered by or
   on behalf of the Company and the Optionee to whom such option shall be
   granted.  The agreement shall provide, among other things, that it does not
   confer upon an Optionee any right to continue in the employ of the Company
   and/or any affiliated corporation or to continue as a director or
   consultant of the Company and/or any affiliated corporation, and that it
   does not interfere in any way with the right of the Company or any such
   affiliated corporation to terminate the employment of the Optionee at any
   time if the Optionee is an employee, to remove the Optionee as a director
   if the Optionee is a director, or to terminate the services of the Optionee
   if the Optionee is a consultant.

   7.   Option Period

        An option may become exercisable immediately or in such installments,
   cumulative or noncumulative, as the Committee may determine.  

   8.   Exercise of Option

        An option may be exercised in accordance with its terms by written
   notice of intent to exercise the option, specifying the number of shares of
   stock with respect to which the option is then being exercised.  The notice
   shall be accompanied by payment in the form of cash or shares of
   ThermoSpectra Common Stock (the "Tendered Shares") with a then current
   market value equal to the option price of the shares to be purchased;
   provided, however, that such Tendered Shares shall have been acquired by
   the Optionee more than six months prior to the date of exercise, unless
   such requirement is waived in writing by the Company.  Against such payment
   the Company shall deliver or cause to be delivered to the Optionee a
   certificate for the number of shares then being purchased, registered in
   the name of the Optionee or other person exercising the option.  If any law
   or applicable regulation of the Securities and Exchange Commission or other
   body having jurisdiction in the premises shall require the Company,
   ThermoSpectra or the Optionee to take any action in connection with shares
   being purchased upon exercise of the option, exercise of the option and
   delivery of the certificate or certificates for such shares shall be
   postponed until completion of the necessary action, which shall be taken at
   the Company's expense.

   9.   Transferability

        Options shall not be transferable, otherwise than by will or the laws
   of descent and distribution, except pursuant to the terms of a qualified
PAGE
<PAGE>
   domestic relations order as defined in the Internal Revenue Code.  Options
   may be exercised during the life of the Optionee only by the Optionee.

   10.  Vesting, Restrictions and Termination of Options

        The Committee, in its sole discretion, may determine the manner in
   which options shall vest, the rights of the Company to repurchase the
   shares issued upon the exercise of any option and the manner in which such
   rights shall lapse, and the terms upon which any option granted shall
   terminate.  The Board of Directors shall have the right to accelerate the
   date of exercise of any installment or to accelerate the lapse of the
   Company's repurchase rights.  All of such terms shall be specified in a
   written option agreement executed and delivered by or on behalf of the
   Company and the Optionee to whom such option shall be granted.

   11.  Adjustment of Number of Shares

        Each stock option agreement shall provide that in the event of any
   stock dividend payable in the Common Stock or any split-up or contraction
   in the number of shares of the Common Stock occurring after the date of the
   agreement and prior to the exercise in full of the option, the number of
   shares for which the option may thereafter be exercised shall be
   proportionately adjusted and the price to be paid for each share subject to
   the option shall be proportionately adjusted.  Each such agreement shall
   also provide that in case of any reclassification or change of outstanding
   shares of the Common Stock or in case of any consolidation or merger of
   ThermoSpectra with or into another company or in case of any sale or
   conveyance to another company or entity of the property of ThermoSpectra as
   a whole or substantially as a whole, the Optionee shall, upon exercise of
   the option, be entitled to receive shares of stock or other securities in
   its place equivalent in kind and value to those shares which he would have
   received if he had exercised the option in full immediately prior to such
   reclassification, change, consolidation, merger, sale or conveyance and had
   continued to hold the shares subject to the option (together with all other
   shares, stock and securities thereafter issued in respect thereof) to the
   time of the exercise of the option; provided, that if any recapitalization
   is to be effected through an increase in the par value of the Common Stock
   without an increase in the number of authorized shares and such new par
   value will exceed the option price under such agreement, the Company shall
   notify the Optionee of such proposed recapitalization, and the Optionee
   shall then have the right, exercisable at any time prior to such
   recapitalization becoming effective, to purchase all of the shares subject
   to the option which he has not theretofore purchased (anything in such
   agreement to the contrary notwithstanding), but if the Optionee fails to
   exercise such right before such recapitalization becomes effective, the
   option price under such agreement shall be appropriately adjusted.  Each
   such agreement shall further provide that upon dissolution or liquidation
   of ThermoSpectra, the option shall terminate, but the Optionee (if at the
   time an employee or director of the Company and/or any one or more of its
   subsidiaries) shall have the right, immediately prior to such dissolution
   or liquidation, to exercise the option to the full extent not theretofore
   exercised; that no adjustment provided for above shall apply to any share
   with respect to which the option has been exercised prior to the effective
   date of such adjustment; and that no fraction of a share or fractional
   shares shall be purchasable or deliverable under such agreement, but in the
   event any adjustment thereunder of the number of shares covered by the
   option shall cause such number to include a fraction of a share, such
   fraction shall be adjusted to the nearest smaller whole number of shares.
PAGE
<PAGE>
   In the event of changes in the outstanding Common Stock by reason of any
   stock dividend, split-up, contraction, reclassification, or change of
   outstanding shares of the Common Stock of the nature contemplated by this
   paragraph 11, the number of shares of Common Stock available for the
   purpose of the Plan as stated in paragraph 3 hereof shall be
   correspondingly adjusted by the Committee.

   12.  Limitation of Rights in Option Stock

        The Optionees shall have no rights as stockholders in respect of
   shares as to which their options shall not have been exercised,
   certificates issued and delivered and payment as herein provided made in
   full, and shall have no rights with respect to such shares not expressly
   conferred by this Plan.

   13.  Stock Reserved

        The Company shall at all times during the term of the options reserve
   and keep available such number of shares of the Common Stock as will be
   sufficient to satisfy the requirements of this Plan and shall pay all other
   fees and expenses necessarily incurred by the Company in connection
   therewith.

   14.  Securities Laws Restrictions

        Each Optionee exercising an option, at the request of the Company,
   will be required to give a representation in form satisfactory to counsel
   for the Company that he will not transfer, sell or otherwise dispose of the
   shares received upon exercise of the option at any time purchased by him,
   upon exercise of any portion of the option, in a manner which would violate
   the Securities Act of 1933, as amended, and the regulations of the
   Securities and Exchange Commission thereunder and the Company may, if
   required or at its discretion, make a notation on any certificates issued
   upon exercise of options to the effect that such certificate may not be
   transferred except after receipt by the Company of an opinion of counsel
   satisfactory to it to the effect that such transfer will not violate such
   Act and such regulations.

   15.  Tax Withholding

        The Company will withhold from any cash payment made pursuant to an
   exercise of an option an amount sufficient to satisfy all federal, state
   and local withholding tax requirements (the "withholding requirements").
   The Committee will have the right to require that the Optionee or other
   appropriate person remit to the Company an amount sufficient to satisfy the
   withholding requirements, or make other arrangements satisfactory to the
   Committee with regard to such requirements, prior to the delivery of any
   Common Stock pursuant to exercise of an option.  If and to the extent that
   such withholding is required, the Committee may permit the Optionee or such
   other person to elect at such time and in such manner as the Committee
   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 requirements.

   16.  Termination and Amendment of Plan

        The Board of Directors may at any time, and from time to time, modify
   or amend the Plan in any respect, except that if at any time the approval
PAGE
<PAGE>
   of the Stockholders of the Company is required as to such modification or
   amendment under Rule 16b-3, the Board of Directors may not effect such
   modification or amendment without such approval.

        The termination or any modification or amendment of the Plan shall
   not, without the consent of an Optionee, affect his or her rights under an
   option previously granted to him or her.  With the consent of the Optionees
   affected, the Board of Directors may amend outstanding option agreements in
   a manner not inconsistent with the Plan.  The Board of Directors shall have
   the right to amend or modify the terms and provisions of the Plan and of
   any outstanding option to the extent necessary to ensure the qualification
   of the Plan under Rule 16b-3.

        Notwithstanding any other provisions hereof, the Plan shall terminate
October 25, 2004 and no options shall be granted hereunder thereafter.

                            THERMOSPECTRA CORPORATION
                              EQUITY INCENTIVE PLAN

   1.   Purpose

        The purpose of this Equity Incentive Plan (the "Plan") is to secure
   for ThermoSpectra 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 two or more members of the Board, each of whom shall be
   deemed a "disinterested person" within the meaning of Rule 16b-3 (or any
   successor rule) of the Securities Exchange Act of 1934 (the "Exchange
   Act").  

   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.
PAGE
<PAGE>
   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.

        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 the par value per share
   of Common Stock.
PAGE
<PAGE>
        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 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 to buy out
   for a payment in cash, shares of Common Stock, deferred stock or restricted
   stock, an option previously granted, based on such terms and conditions as
   the Board shall establish and communicate to the option holder at the time
   that such offer is made.

        6.1.6 Special Rules for Incentive Stock Options.  Each provision of
   the Plan and each option agreement evidencing an 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 stock options
   may be granted only to employees of the Company and its subsidiaries.  The
   exercise price of an incentive stock 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
PAGE
<PAGE>
   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.

        6.2   Restricted and Unrestricted Stock

        An Award of restricted stock entitles the recipient thereof to acquire
   shares of Common Stock upon payment of the purchase price subject to
   restrictions specified in the instrument evidencing the Award.

        6.2.1 Restricted Stock Awards.  Awards of restricted stock shall be
   evidenced by restricted stock agreements.  Such agreements shall conform to
   the requirements of the Plan, and may contain such other provisions
   (including restriction and forfeiture provisions, change of control,
   protection in the event of mergers, consolidations, dissolutions and
   liquidations) as the Board shall deem advisable.

        6.2.2 Restrictions.  Until the restrictions specified in a restricted
   stock agreement shall lapse, restricted stock may not be sold, assigned,
   transferred, pledged or otherwise encumbered or disposed of, and upon
   certain conditions specified in the restricted stock agreement, must be
   resold to the Company for the price, if any, specified in such agreement.
   The restrictions shall lapse at such time or times, and on such conditions,
   as the Board may specify.  The Board may at any time accelerate the time at
   which the restrictions on all or any part of the shares shall lapse.

        6.2.3 Rights as a Stockholder.  A Participant who acquires shares of
   restricted stock will have all of the rights of a Stockholder with respect
   to such shares including the right to receive dividends and to vote such
   shares.  Unless the Board otherwise determines, certificates evidencing
   shares of restricted stock will remain in the possession of the Company
   until such shares are free of all restrictions under the Plan.

        6.2.4 Purchase Price.  The purchase price of shares of restricted
   stock shall be determined by the Board, in its sole discretion, but such
   price may not be less than the par value of such shares.

        6.2.5 Other Awards Settled With Restricted Stock.  The Board may
   provide that any or all the Common Stock delivered pursuant to an Award
   will be restricted stock.
     
        6.2.6 Unrestricted Stock.  The Board may, in its sole discretion,
   sell to any Participant shares of Common Stock free of restrictions under
   the Plan for a price determined by the Board, but which may not be less
   than the par value per share of the Common Stock.

        6.3   Deferred Stock

        6.3.1 Deferred Stock Award.  A deferred stock Award entitles the
   recipient to receive shares of deferred stock which is Common Stock to be
   delivered in the future.  Delivery of the Common Stock will take place at
   such time or times, and on such conditions, as the Board may specify.  The
PAGE
<PAGE>
   Board may at any time accelerate the time at which delivery of all or any
   part of the Common Stock will take place.

        6.3.2 Other Awards Settled with Deferred Stock.  The Board may, at
   the time any Award described in this Section 6 is granted, provide that, at
   the time Common Stock would otherwise be delivered pursuant to the Award,
   the Participant will instead receive an instrument evidencing the right to
   future delivery of deferred stock.

        6.4   Performance Awards

        6.4.1 Performance Awards.  A performance Award entitles the recipient
   to receive, without payment, an Amount, in cash or Common Stock or a
   combination thereof (such form to be determined by the Board), following
   the attainment of performance goals.  Performance goals may be related to
   personal performance, corporate performance, departmental performance or
   any other category of performance deemed by the Board to be important to
   the success of the Company.  The Board will determine the performance
   goals, the period or periods during which performance is to be measured and
   all other terms and conditions applicable to the Award.

        6.4.2 Other Awards Subject to Performance Conditions.  The Board may,
   at the time any Award described in this Section 6 is granted, impose the
   condition (in addition to any conditions specified or authorized in this
   Section 6 of the Plan) that performance goals be met prior to the
   Participant's realization of any payment or benefit under the Award.

   7.   Purchase Price and Payment

        Except as otherwise provided in the Plan, the purchase price of Common
   Stock to be acquired pursuant to an Award shall be the price determined by
   the Board, provided that such price shall not be less than the par value of
   the Common Stock.   Except as otherwise provided in the Plan, the Board may
   determine the method of payment of the exercise price or purchase price of
   an Award granted under the Plan and the form of payment.  The Board may
   determine that all or any part of the purchase price of 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,
PAGE
<PAGE>
   discharging all the participant's income tax liabilities arising from all
   payments under the Plan.

   9.   Change in Control

        9.1   Impact of Event

        In the event of a "Change in Control" as defined in Section 9.2, the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

        (a) Any stock options or other stock-based Awards awarded under the
        Plan that were not previously exercisable and vested shall become
        fully exercisable and vested.

        (b) Awards of restricted stock and other stock-based Awards subject to
        restrictions and to the extent not fully vested, shall become fully
        vested and all such restrictions shall lapse so that shares issued
        pursuant to such Awards shall be 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.

        9.2   Definition of "Change in Control"

        "Change in Control" means any one of the following events:  (i) when,
   any Person is or becomes the beneficial owner (as defined in Section 13(d)
   of the Exchange Act and the Rules and Regulations thereunder), together
   with all Affiliates and Associates (as such terms are used in Rule 12b-2 of
   the General Rules and Regulations of the Exchange Act) of such Person,
   directly or indirectly, of 50% or more of the outstanding Common Stock of
   the Company or its parent corporation, Thermo Instrument Systems Inc.
   ("Thermo Instrument"), or the 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
   applicable issuer, (ii) the failure of the Prior Directors to constitute a
   majority of the Board of Directors of the Company, Thermo Instrument or
   Thermo Electron, as the case may be, at any time within two years following
   any Electoral Event, or (iii) any other event that the Prior Directors
   shall determine constitutes an effective change in the control of the
   Company, Thermo Instrument or Thermo Electron.  As used in the preceding
   sentence, the following capitalized terms shall have the respective
   meanings set forth below:

        (a) "Person" shall include any natural person, any entity, any
        "affiliate" of any such natural person or entity as such term is
        defined in Rule 405 under the Securities Act of 1933 and any "group"
        (within the meaning of such term in Rule 13d-5 under the Exchange
        Act);

        (b) "Prior Directors" shall mean the persons sitting on the Company's,
        Thermo Instrument's or Thermo Electron's Board of Directors, as the
PAGE
<PAGE>
        case may be, immediately prior to any Electoral Event (or, if there
        has been no Electoral Event, those persons sitting on the applicable
        Board of Directors on the date of this Agreement) and any future
        director of the Company, Thermo Instrument or Thermo Electron who has
        been nominated or elected by a majority of the Prior Directors who are
        then members of the Board of Directors of the Company, Thermo
        Instrument or Thermo Electron, as the case may be; and 

        (c) "Electoral Event" shall mean any contested election of Directors,
        or any tender or exchange offer for the Company's, Thermo Instrument's
        or Thermo Electron's Common Stock, not approved by the Prior
        Directors, by any Person other than the Company, Thermo Instrument,
        Thermo Electron or a majority-owned subsidiary of Thermo Electron.

   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.
PAGE
<PAGE>
        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

        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 otherwise specifically provided by the Board in the case of
   participants who are not reporting persons under Section 16 of the Exchange
   Act, 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 the laws of descent and distribution, except pursuant to the
   terms of a qualified domestic relations order as defined in the Code, 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).

        10.6  Adjustments in the Event of Certain Transactions

        (a)  In the event of a stock dividend, stock split or combination of
   shares, recapitalization or other change in the Company's capitalization,
   or other distribution with respect to common Stockholders other than normal
   cash dividends, 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, 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 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.
PAGE
<PAGE>
        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 and its subsidiaries shall not be deemed
   termination of employment.

        10.8  Other Employee Benefits

        The value of an Award granted to a Participant who is an employee, and
   the amount of any compensation deemed to be received by an employee as a
   result of any exercise or purchase of Common Stock pursuant to an Award or
   sale of shares received under the Plan, will not constitute "earnings" or
   "compensation" with respect to which any other employee benefits of such
   employee are determined, including without limitation benefits under any
   pension, stock ownership, stock purchase, life insurance, medical, health,
   disability or salary continuation plan.

        10.9  Legal Holidays

        If any day on or before which action under the Plan must be taken
   falls on a Saturday, Sunday or legal holiday, such action may be taken on
   the next succeeding day not a Saturday, Sunday or legal holiday.

        10.10 Foreign Nationals

        Without amending the Plan, Awards may be granted to persons who are
   foreign nationals or employed outside the United States or both, on such
   terms and conditions different from those specified in the Plan, as may, in
   the judgment of the Board, be necessary or desirable to further the purpose
   of the Plan.

   11.  Termination and Amendment

        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 Exchange Act.  No amendment of the Plan or any agreement
   evidencing Awards under the Plan may adversely affect the rights of any
   participant under any Award previously granted without such participant's
   consent.

                                                                 Exhibit 10.60
                              THERMO FIBERTEK INC.
                              EQUITY INCENTIVE PLAN

   1.   Purpose

        The purpose of this Equity Incentive Plan (the "Plan") is to secure
   for Thermo Fibertek Inc. (the "Company") and its Stockholders the benefits
   arising from capital stock ownership by employees 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 two or more members of the Board, each of whom shall be
   deemed a "disinterested person" within the meaning of Rule 16b-3 (or any
   successor rule) of the Securities Exchange Act of 1934 (the "Exchange
   Act").  

   3.   Effective Date

        The Plan shall be effective as of February 22, 1994, subject to the
   approval of the Plan by the Company's Stockholders at the next annual
   meeting of 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.
PAGE
<PAGE>
   4.   Shares Subject to the Plan

        Subject to adjustment as provided in Section 10.6, the total number of
   shares of  Common Stock reserved and available for distribution under the
   Plan shall be 1,000,000 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 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.

        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").
PAGE
<PAGE>
        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 the par 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 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 to buy
   out for a payment in cash, shares of Common Stock, deferred stock or
   restricted stock, an option previously granted, based on such terms and
   conditions as the Board shall establish and communicate to the option
   holder at the time that such offer is made.

        6.1.6     Special Rules for Incentive Stock Options.  Each provision
   of the Plan and each option agreement evidencing an incentive stock option
   shall be construed so that each incentive stock option shall be an
   incentive stock option as defined in Section 422 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 stock options
PAGE
<PAGE>
   may be granted only to employees of the Company and its subsidiaries.  The
   exercise price of an incentive stock 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.

        6.2  Restricted and Unrestricted Stock

        An Award of restricted stock entitles the recipient thereof to acquire
   shares of Common Stock upon payment of the purchase price subject to
   restrictions specified in the instrument evidencing the Award.

        6.2.1     Restricted Stock Awards.  Awards of restricted stock shall
   be evidenced by restricted stock agreements.  Such agreements shall conform
   to the requirements of the Plan, and may contain such other provisions
   (including restriction and forfeiture provisions, change of control,
   protection in the event of mergers, consolidations, dissolutions and
   liquidations) as the Board shall deem advisable.

        6.2.2     Restrictions.  Until the restrictions specified in a
   restricted stock agreement shall lapse, restricted stock may not be sold,
   assigned, transferred, pledged or otherwise encumbered or disposed of, and
   upon certain conditions specified in the restricted stock agreement, must
   be resold to the Company for the price, if any, specified in such
   agreement.  The restrictions shall lapse at such time or times, and on such
   conditions, as the Board may specify.  The Board may at any time accelerate
   the time at which the restrictions on all or any part of the shares shall
   lapse.

        6.2.3     Rights as a Stockholder.  A Participant who acquires shares
   of restricted stock will have all of the rights of a Stockholder with
   respect to such shares including the right to receive dividends and to vote
   such shares.  Unless the Board otherwise determines, certificates
   evidencing shares of restricted stock will remain in the possession of the
   Company until such shares are free of all restrictions under the Plan.

        6.2.4     Purchase Price.  The purchase price of shares of restricted
   stock shall be determined by the Board, in its sole discretion, but such
   price may not be less than the par value of such shares.

        6.2.5     Other Awards Settled With Restricted Stock.  The Board may
   provide that any or all the Common Stock delivered pursuant to an Award
   will be restricted stock.
     
        6.2.6     Unrestricted Stock.  The Board may, in its sole discretion,
   sell to any Participant shares of Common Stock free of restrictions under
   the Plan for a price determined by the Board, but which may not be less
   than the par value per share of the Common Stock.
PAGE
<PAGE>
        6.3  Deferred Stock

        6.3.1     Deferred Stock Award.  A deferred stock Award entitles the
   recipient to receive shares of deferred stock which is Common Stock to be
   delivered in the future.  Delivery of the Common Stock will take place at
   such time or times, and on such conditions, as the Board may specify.  The
   Board may at any time accelerate the time at which delivery of all or any
   part of the Common Stock will take place.

        6.3.2     Other Awards Settled with Deferred Stock.  The Board may, at
   the time any Award described in this Section 6 is granted, provide that, at
   the time Common Stock would otherwise be delivered pursuant to the Award,
   the Participant will instead receive an instrument evidencing the right to
   future delivery of deferred stock.

        6.4  Performance Awards

        6.4.1     Performance Awards.  A performance Award entitles the
   recipient to receive, without payment, an Amount, in cash or Common Stock
   or a combination thereof (such form to be determined by the Board),
   following the attainment of performance goals.  Performance goals may be
   related to personal performance, corporate performance, departmental
   performance or any other category of performance deemed by the Board to be
   important to the success of the Company.  The Board will determine the
   performance goals, the period or periods during which performance is to be
   measured and all other terms and conditions applicable to the Award.

        6.4.2     Other Awards Subject to Performance Conditions.  The Board
   may, at the time any Award described in this Section 6 is granted, impose
   the condition (in addition to any conditions specified or authorized in
   this Section 6 of the Plan) that performance goals be met prior to the
   Participant's realization of any payment or benefit under the Award.

   7.   Purchase Price and Payment

        Except as otherwise provided in the Plan, the purchase price of Common
   Stock to be acquired pursuant to an Award shall be the price determined by
   the Board, provided that such price shall not be less than the par value of
   the Common Stock.   Except as otherwise provided in the Plan, the Board may
   determine the method of payment of the exercise price or purchase price of
   an Award granted under the Plan and the form of payment.  The Board may
   determine that all or any part of the purchase price of 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.
PAGE
<PAGE>
        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 participant's income tax liabilities arising from all
   payments under the Plan.

   9.   Change in Control

        9.1  Impact of Event

        In the event of a "Change in Control" as defined in Section 9.2, the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

        (a) Any stock options or other stock-based Awards awarded under the
        Plan that were not previously exercisable and vested shall become
        fully exercisable and vested.

        (b) Awards of restricted stock and other stock-based Awards subject to
        restrictions and to the extent not fully vested, shall become fully
        vested and all such restrictions shall lapse so that shares issued
        pursuant to such Awards shall be 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.

        9.2  Definition of "Change in Control"

        "Change in Control" means any one of the following events:  (i) when,
   any Person is or becomes the beneficial owner (as defined in Section 13(d)
   of the Exchange Act and the Rules and Regulations thereunder), together
   with all Affiliates and Associates (as such terms are used in Rule 12b-2 of
   the General Rules and Regulations of the Exchange Act) of such Person,
   directly or indirectly, of 50% or more of the outstanding Common Stock of
   the Company or the 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 or Thermo
   Electron, as the case may be, (ii) the failure of the Prior Directors to
   constitute a majority of the Board of the Company or the Board of Directors
   of Thermo Electron, as the case may be, at any time within two years
   following any Electoral Event, or (iii) any other event that the Prior
   Directors shall determine constitutes an effective change in the control of
   the Company or Thermo Electron.  As used in the preceding sentence, the
   following capitalized terms shall have the respective meanings set forth
   below:

        (a) "Person" shall include any natural person, any entity, any
        "affiliate" of any such natural person or entity as such term is
        defined in Rule 405 under the Securities Act of 1933 and any "group"
PAGE
<PAGE>
        (within the meaning of such term in Rule 13d-5 under the Exchange
        Act);

        (b) "Prior Directors" shall mean the persons sitting on the Company's
        or Thermo Electron's Board of Directors, as the case may be,
        immediately prior to any Electoral Event (or, if there has been no
        Electoral Event, those persons sitting on the applicable Board of
        Directors on the date of this Agreement) and any future director of
        the Company or Thermo Electron who has been nominated or elected by a
        majority of the Prior Directors who are then members of the Board of
        Directors of the Company or Thermo Electron, as the case may be; and 

        (c) "Electoral Event" shall mean any contested election of Directors,
        or any tender or exchange offer for the Company's or Thermo Electron's
        Common Stock, not approved by the Prior Directors, by any Person other
        than the Company Thermo Electron or a subsidiary of Thermo Electron.

   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
PAGE
<PAGE>
   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

        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 otherwise specifically provided by the Board in the case of
   participants who are not reporting persons under Section 16 of the Exchange
   Act, 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 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).

        10.6 Adjustments in the Event of Certain Transactions

        (a)  In the event of a stock dividend, stock split or combination of
   shares, recapitalization or other change in the Company's capitalization,
   or other distribution with respect to common Stockholders other than normal
   cash dividends, 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, 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 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.
PAGE
<PAGE>
        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 and its subsidiaries shall not be deemed
   termination of employment.

        10.8 Other Employee Benefits

        The value of an Award granted to a Participant who is an employee, and
   the amount of any compensation deemed to be received by an employee as a
   result of any exercise or purchase of Common Stock pursuant to an Award or
   sale of shares received under the Plan, will not constitute "earnings" or
   "compensation" with respect to which any other employee benefits of such
   employee are determined, including without limitation benefits under any
   pension, stock ownership, stock purchase, life insurance, medical, health,
   disability or salary continuation plan.

        10.9 Legal Holidays

        If any day on or before which action under the Plan must be taken
   falls on a Saturday, Sunday or legal holiday, such action may be taken on
   the next succeeding day not a Saturday, Sunday or legal holiday.

        10.10 Foreign Nationals

        Without amending the Plan, Awards may be granted to persons who are
   foreign nationals or employed outside the United States or both, on such
   terms and conditions different from those specified in the Plan, as may, in
   the judgment of the Board, be necessary or desirable to further the purpose
   of the Plan.

   11.  Termination and Amendment

        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 Exchange Act.  No amendment of the Plan or any agreement
   evidencing Awards under the Plan may adversely affect the rights of any
   participant under any Award previously granted without such participant's
   consent.

                                                             Exhibit 10.63
                            THERMO POWER CORPORATION
                              EQUITY INCENTIVE PLAN

   1.   Purpose

        The purpose of this Equity Incentive Plan (the "Plan") is to secure
   for Thermo Power Corporation (the "Company") and its Stockholders the
   benefits arising from capital stock ownership by employees 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 two or more members of the Board, each of whom shall be
   deemed a "disinterested person" within the meaning of Rule 16b-3 (or any
   successor rule) of the Securities Exchange Act of 1934 (the "Exchange
   Act").  

   3.   Effective Date

        The Plan shall be effective as of December 10, 1993, subject to the
   approval of the Plan by the Corporation's Stockholders at the next annual
   meeting of 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.
PAGE
<PAGE>
   4.   Shares Subject to the Plan

        Subject to adjustment as provided in Section 10.6, the total number of
   shares of Common Stock reserved and available for distribution under the
   Plan shall be 750,000 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 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.

        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").
PAGE
<PAGE>
        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 the par 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 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 to buy out
   for a payment in cash, shares of Common Stock, deferred stock or restricted
   stock, an option previously granted, based on such terms and conditions as
   the Board shall establish and communicate to the option holder at the time
   that such offer is made.

        6.1.6 Special Rules for Incentive Stock Options.  Each provision of
   the Plan and each option agreement evidencing an 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 stock options
PAGE
<PAGE>
   may be granted only to employees of the Company and its subsidiaries.  The
   exercise price of an incentive stock 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.

        6.2   Restricted and Unrestricted Stock

        An Award of restricted stock entitles the recipient thereof to acquire
   shares of Common Stock upon payment of the purchase price subject to
   restrictions specified in the instrument evidencing the Award.

        6.2.1 Restricted Stock Awards.  Awards of restricted stock shall be
   evidenced by restricted stock agreements.  Such agreements shall conform to
   the requirements of the Plan, and may contain such other provisions
   (including restriction and forfeiture provisions, change of control,
   protection in the event of mergers, consolidations, dissolutions and
   liquidations) as the Board shall deem advisable.

        6.2.2 Restrictions.  Until the restrictions specified in a restricted
   stock agreement shall lapse, restricted stock may not be sold, assigned,
   transferred, pledged or otherwise encumbered or disposed of, and upon
   certain conditions specified in the restricted stock agreement, must be
   resold to the Company for the price, if any, specified in such agreement.
   The restrictions shall lapse at such time or times, and on such conditions,
   as the Board may specify.  The Board may at any time accelerate the time at
   which the restrictions on all or any part of the shares shall lapse.

        6.2.3 Rights as a Stockholder.  A Participant who acquires shares of
   restricted stock will have all of the rights of a Stockholder with respect
   to such shares including the right to receive dividends and to vote such
   shares.  Unless the Board otherwise determines, certificates evidencing
   shares of restricted stock will remain in the possession of the Company
   until such shares are free of all restrictions under the Plan.

        6.2.4 Purchase Price.  The purchase price of shares of restricted
   stock shall be determined by the Board, in its sole discretion, but such
   price may not be less than the par value of such shares.

        6.2.5 Other Awards Settled With Restricted Stock.  The Board may
   provide that any or all the Common Stock delivered pursuant to an Award
   will be restricted stock.
     
        6.2.6 Unrestricted Stock.  The Board may, in its sole discretion,
   sell to any Participant shares of Common Stock free of restrictions under
   the Plan for a price determined by the Board, but which may not be less
   than the par value per share of the Common Stock.

        6.3   Deferred Stock

        6.3.1 Deferred Stock Award.  A deferred stock Award entitles the
   recipient to receive shares of deferred stock which is Common Stock to be
PAGE
<PAGE>
   delivered in the future.  Delivery of the Common Stock will take place at
   such time or times, and on such conditions, as the Board may specify.  The
   Board may at any time accelerate the time at which delivery of all or any
   part of the Common Stock will take place.

        6.3.2 Other Awards Settled with Deferred Stock.  The Board may, at
   the time any Award described in this Section 6 is granted, provide that, at
   the time Common Stock would otherwise be delivered pursuant to the Award,
   the Participant will instead receive an instrument evidencing the right to
   future delivery of deferred stock.

        6.4   Performance Awards

        6.4.1 Performance Awards.  A performance Award entitles the recipient
   to receive, without payment, an Amount, in cash or Common Stock or a
   combination thereof (such form to be determined by the Board), following
   the attainment of performance goals.  Performance goals may be related to
   personal performance, corporate performance, departmental performance or
   any other category of performance deemed by the Board to be important to
   the success of the Company.  The Board will determine the performance
   goals, the period or periods during which performance is to be measured and
   all other terms and conditions applicable to the Award.

        6.4.2 Other Awards Subject to Performance Conditions.  The Board may,
   at the time any Award described in this Section 6 is granted, impose the
   condition (in addition to any conditions specified or authorized in this
   Section 6 of the Plan) that performance goals be met prior to the
   Participant's realization of any payment or benefit under the Award.

   7.   Purchase Price and Payment

        Except as otherwise provided in the Plan, the purchase price of Common
   Stock to be acquired pursuant to an Award shall be the price determined by
   the Board, provided that such price shall not be less than the par value of
   the Common Stock.   Except as otherwise provided in the Plan, the Board may
   determine the method of payment of the exercise price or purchase price of
   an Award granted under the Plan and the form of payment.  The Board may
   determine that all or any part of the purchase price of 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
PAGE
<PAGE>
   a grossed-up basis necessary to make him or her whole after tax,
   discharging all the participant's income tax liabilities arising from all
   payments under the Plan.

   9.   Change in Control

        9.1   Impact of Event

        In the event of a "Change in Control" as defined in Section 9.2, the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

        (a) Any stock options or other stock-based Awards awarded under the
        Plan that were not previously exercisable and vested shall become
        fully exercisable and vested.

        (b) Awards of restricted stock and other stock-based Awards subject to
        restrictions and to the extent not fully vested, shall become fully
        vested and all such restrictions shall lapse so that shares issued
        pursuant to such Awards shall be 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.

        9.2   Definition of "Change in Control"

        "Change in Control" means any one of the following events:  (i) when,
   any Person is or becomes the beneficial owner (as defined in Section 13(d)
   of the Exchange Act and the Rules and Regulations thereunder), together
   with all Affiliates and Associates (as such terms are used in Rule 12b-2 of
   the General Rules and Regulations of the Exchange Act) of such Person,
   directly or indirectly, of 50% or more of the outstanding Common Stock of
   the Company, or the 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 or Thermo
   Electron, as the case may be, (ii) the failure of the Prior Directors to
   constitute a majority of the Board of the Company or of the Board of
   Directors of Thermo Electron, as the case may be, at any time within two
   years following any Electoral Event, or (iii) any other event that the
   Prior Directors shall determine constitutes an effective change in the
   control of the Company or Thermo Electron.  As used in the preceding
   sentence, the following capitalized terms shall have the respective
   meanings set forth below:

        (a) "Person" shall include any natural person, any entity, any
        "affiliate" of any such natural person or entity as such term is
        defined in Rule 405 under the Securities Act of 1933 and any "group"
        (within the meaning of such term in Rule 13d-5 under the Exchange
        Act);

        (b) "Prior Directors" shall mean the persons sitting on the Company's
        or Thermo Electron's Board of Directors, as the case may be,
PAGE
<PAGE>
        immediately prior to any Electoral Event (or, if there has been no
        Electoral Event, those persons sitting on the applicable Board of
        Directors on the date of this Agreement) and any future director of
        the Company or Thermo Electron who has been nominated or elected by a
        majority of the Prior Directors who are then members of the Board of
        Directors of the Company or Thermo Electron, as the case may be; and 

        (c) "Electoral Event" shall mean any contested election of Directors,
        or any tender or exchange offer for the Company's or Thermo Electron's
        Common Stock, not approved by the Prior Directors, by any Person other
        than the Company, Thermo Electron or a subsidiary of Thermo Electron.

   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.
PAGE
<PAGE>
        10.4  Tax Withholding

        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 otherwise specifically provided by the Board in the case of
   participants who are not reporting persons under Section 16 of the Exchange
   Act, 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 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).

        10.6  Adjustments in the Event of Certain Transactions

        (a)  In the event of a stock dividend, stock split or combination of
   shares, recapitalization or other change in the Company's capitalization,
   or other distribution with respect to common Stockholders other than normal
   cash dividends, 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, 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 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
PAGE
<PAGE>
   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 and its subsidiaries shall not be deemed
   termination of employment.

        10.8  Other Employee Benefits

        The value of an Award granted to a Participant who is an employee, and
   the amount of any compensation deemed to be received by an employee as a
   result of any exercise or purchase of Common Stock pursuant to an Award or
   sale of shares received under the Plan, will not constitute "earnings" or
   "compensation" with respect to which any other employee benefits of such
   employee are determined, including without limitation benefits under any
   pension, stock ownership, stock purchase, life insurance, medical, health,
   disability or salary continuation plan.

        10.9  Legal Holidays

        If any day on or before which action under the Plan must be taken
   falls on a Saturday, Sunday or legal holiday, such action may be taken on
   the next succeeding day not a Saturday, Sunday or legal holiday.

        10.10 Foreign Nationals

        Without amending the Plan, Awards may be granted to persons who are
   foreign nationals or employed outside the United States or both, on such
   terms and conditions different from those specified in the Plan, as may, in
   the judgment of the Board, be necessary or desirable to further the purpose
   of the Plan.

   11.  Termination and Amendment

        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 Exchange Act.  No amendment of the Plan or any agreement
   evidencing Awards under the Plan may adversely affect the rights of any
   participant under any Award previously granted without such participant's
   consent.

                                                                 Exhibit 10.69
                            THERMEDICS DETECTION INC.
                              EQUITY INCENTIVE PLAN

   1.   Purpose

        The purpose of this Equity Incentive Plan (the "Plan") is to secure
   for Thermedics Detection Inc. (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 two or more members of the Board, each of whom shall be
   deemed a "disinterested person" within the meaning of Rule 16b-3 (or any
   successor rule) of the Securities Exchange Act of 1934 (the "Exchange
   Act").  

   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.
PAGE
<PAGE>
   4.   Shares Subject to the Plan

        Subject to adjustment as provided in Section 10.6, the total number of
   shares of the common stock, $.10 par value per share, of the Company (the
   "Common Stock"), reserved and available for distribution under the Plan
   shall be 500,000 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.

        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").
PAGE
<PAGE>
        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 the par 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 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 to buy
   out for a payment in cash, shares of Common Stock, deferred stock or
   restricted stock, an option previously granted, based on such terms and
   conditions as the Board shall establish and communicate to the option
   holder at the time that such offer is made.

        6.1.6     Special Rules for Incentive Stock Options.  Each provision
   of the Plan and each option agreement evidencing an 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 stock options
PAGE
<PAGE>
   may be granted only to employees of the Company and its subsidiaries.  The
   exercise price of an incentive stock 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.

        6.2  Restricted and Unrestricted Stock

        An Award of restricted stock entitles the recipient thereof to acquire
   shares of Common Stock upon payment of the purchase price subject to
   restrictions specified in the instrument evidencing the Award.

        6.2.1     Restricted Stock Awards.  Awards of restricted stock shall
   be evidenced by restricted stock agreements.  Such agreements shall conform
   to the requirements of the Plan, and may contain such other provisions
   (including restriction and forfeiture provisions, change of control,
   protection in the event of mergers, consolidations, dissolutions and
   liquidations) as the Board shall deem advisable.

        6.2.2     Restrictions.  Until the restrictions specified in a
   restricted stock agreement shall lapse, restricted stock may not be sold,
   assigned, transferred, pledged or otherwise encumbered or disposed of, and
   upon certain conditions specified in the restricted stock agreement, must
   be resold to the Company for the price, if any, specified in such
   agreement.  The restrictions shall lapse at such time or times, and on such
   conditions, as the Board may specify.  The Board may at any time accelerate
   the time at which the restrictions on all or any part of the shares shall
   lapse.

        6.2.3     Rights as a Stockholder.  A Participant who acquires shares
   of restricted stock will have all of the rights of a Stockholder with
   respect to such shares including the right to receive dividends and to vote
   such shares.  Unless the Board otherwise determines, certificates
   evidencing shares of restricted stock will remain in the possession of the
   Company until such shares are free of all restrictions under the Plan.

        6.2.4     Purchase Price.  The purchase price of shares of restricted
   stock shall be determined by the Board, in its sole discretion, but such
   price may not be less than the par value of such shares.

        6.2.5     Other Awards Settled With Restricted Stock.  The Board may
   provide that any or all the Common Stock delivered pursuant to an Award
   will be restricted stock.
     
        6.2.6     Unrestricted Stock.  The Board may, in its sole discretion,
   sell to any Participant shares of Common Stock free of restrictions under
   the Plan for a price determined by the Board, but which may not be less
   than the par value per share of the Common Stock.
PAGE
<PAGE>
        6.3  Deferred Stock

        6.3.1     Deferred Stock Award.  A deferred stock Award entitles the
   recipient to receive shares of deferred stock which is Common Stock to be
   delivered in the future.  Delivery of the Common Stock will take place at
   such time or times, and on such conditions, as the Board may specify.  The
   Board may at any time accelerate the time at which delivery of all or any
   part of the Common Stock will take place.

        6.3.2     Other Awards Settled with Deferred Stock.  The Board may, at
   the time any Award described in this Section 6 is granted, provide that, at
   the time Common Stock would otherwise be delivered pursuant to the Award,
   the Participant will instead receive an instrument evidencing the right to
   future delivery of deferred stock.

        6.4  Performance Awards

        6.4.1     Performance Awards.  A performance Award entitles the
   recipient to receive, without payment, an Amount, in cash or Common Stock
   or a combination thereof (such form to be determined by the Board),
   following the attainment of performance goals.  Performance goals may be
   related to personal performance, corporate performance, departmental
   performance or any other category of performance deemed by the Board to be
   important to the success of the Company.  The Board will determine the
   performance goals, the period or periods during which performance is to be
   measured and all other terms and conditions applicable to the Award.

        6.4.2     Other Awards Subject to Performance Conditions.  The Board
   may, at the time any Award described in this Section 6 is granted, impose
   the condition (in addition to any conditions specified or authorized in
   this Section 6 of the Plan) that performance goals be met prior to the
   Participant's realization of any payment or benefit under the Award.

   7.   Purchase Price and Payment

        Except as otherwise provided in the Plan, the purchase price of Common
   Stock to be acquired pursuant to an Award shall be the price determined by
   the Board, provided that such price shall not be less than the par value of
   the Common Stock.   Except as otherwise provided in the Plan, the Board may
   determine the method of payment of the exercise price or purchase price of
   an Award granted under the Plan and the form of payment.  The Board may
   determine that all or any part of the purchase price of 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.
PAGE
<PAGE>
        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 participant's income tax liabilities arising from all
   payments under the Plan.

   9.   Change in Control

        9.1  Impact of Event

        In the event of a "Change in Control" as defined in Section 9.2, the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

        (a) Any stock options or other stock-based Awards awarded under the
        Plan that were not previously exercisable and vested shall become
        fully exercisable and vested.

        (b) Awards of restricted stock and other stock-based Awards subject to
        restrictions and to the extent not fully vested, shall become fully
        vested and all such restrictions shall lapse so that shares issued
        pursuant to such Awards shall be 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.

        9.2  Definition of "Change in Control"

        "Change in Control" means any one of the following events:  (i) when,
   any Person is or becomes the beneficial owner (as defined in Section 13(d)
   of the Exchange Act and the Rules and Regulations thereunder), together
   with all Affiliates and Associates (as such terms are used in Rule 12b-2 of
   the General Rules and Regulations of the Exchange Act) of such Person,
   directly or indirectly, of 50% or more of the outstanding Common Stock of
   the Company or its parent corporation, Thermedics Inc. ("Thermedics"), or
   the 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 applicable issuer, (ii) the failure of the
   Prior Directors to constitute a majority of the Board of Directors of the
   Company, Thermedics or Thermo Electron, as the case may be, at any time
   within two years following any Electoral Event, or (iii) any other event
   that the Prior Directors shall determine constitutes an effective change in
   the control of the Company, Thermedics or Thermo Electron.  As used in the
   preceding sentence, the following capitalized terms shall have the
   respective meanings set forth below:

        (a) "Person" shall include any natural person, any entity, any
        "affiliate" of any such natural person or entity as such term is
        defined in Rule 405 under the Securities Act of 1933 and any "group"
PAGE
<PAGE>
        (within the meaning of such term in Rule 13d-5 under the Exchange
        Act);

        (b) "Prior Directors" shall mean the persons sitting on the Company's,
        Thermedics' or Thermo Electron's Board of Directors, as the case may
        be, immediately prior to any Electoral Event (or, if there has been no
        Electoral Event, those persons sitting on the applicable Board of
        Directors on the date of this Agreement) and any future director of
        the Company, Thermedics or Thermo Electron who has been nominated or
        elected by a majority of the Prior Directors who are then members of
        the Board of Directors of the Company, Thermedics or Thermo Electron,
        as the case may be; and 

        (c) "Electoral Event" shall mean any contested election of Directors,
        or any tender or exchange offer for the Company's, Thermedics' or
        Thermo Electron's Common Stock, not approved by the Prior Directors,
        by any Person other than the Company, Thermedics, Thermo Electron or a
        majority-owned subsidiary of Thermo Electron.

   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
PAGE
<PAGE>
   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

        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 otherwise specifically provided by the Board in the case of
   participants who are not reporting persons under Section 16 of the Exchange
   Act, 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 the laws of descent and distribution, except pursuant to the
   terms of a qualified domestic relations order as defined in the Code, 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).

        10.6 Adjustments in the Event of Certain Transactions

        (a)  In the event of a stock dividend, stock split or combination of
   shares, recapitalization or other change in the Company's capitalization,
   or other distribution with respect to common Stockholders other than normal
   cash dividends, 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, 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 adjustments other than those required by law may
PAGE
<PAGE>
   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 and its subsidiaries shall not be deemed
   termination of employment.

        10.8 Other Employee Benefits

        The value of an Award granted to a Participant who is an employee, and
   the amount of any compensation deemed to be received by an employee as a
   result of any exercise or purchase of Common Stock pursuant to an Award or
   sale of shares received under the Plan, will not constitute "earnings" or
   "compensation" with respect to which any other employee benefits of such
   employee are determined, including without limitation benefits under any
   pension, stock ownership, stock purchase, life insurance, medical, health,
   disability or salary continuation plan.

        10.9 Legal Holidays

        If any day on or before which action under the Plan must be taken
   falls on a Saturday, Sunday or legal holiday, such action may be taken on
   the next succeeding day not a Saturday, Sunday or legal holiday.

        10.10 Foreign Nationals

        Without amending the Plan, Awards may be granted to persons who are
   foreign nationals or employed outside the United States or both, on such
   terms and conditions different from those specified in the Plan, as may, in
   the judgment of the Board, be necessary or desirable to further the purpose
   of the Plan.

   11.  Termination and Amendment

        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 Exchange Act.  No amendment of the Plan or any agreement
PAGE
<PAGE>
   evidencing Awards under the Plan may adversely affect the rights of any
   participant under any Award previously granted without such participant's
   consent.

 Notes to Consolidated Financial Statements

 1.   Summary of Significant Accounting Policies

 Relationship with Thermo Electron Corporation
 Thermo Instrument Systems Inc. (the Company) was incorporated on May 28,
 1986, as a wholly owned subsidiary of Thermo Electron Corporation (Thermo
 Electron). As of December 31, 1994, Thermo Electron owned 39,634,271 shares
 of the Company's common stock, representing 83% of such stock outstanding.

 Principles of Consolidation
 The accompanying financial statements include the accounts of the Company,
 its wholly owned subsidiaries, and its 86%-owned subsidiary, ThermoSpectra
 Corporation (ThermoSpectra). All material intercompany accounts and
 transactions have been eliminated. The Company accounts for investments in
 businesses in which it owns between 20% and 50% using the equity method
 (Note 3).

 Fiscal Year
 The Company has adopted a fiscal year ending the Saturday nearest December
 31. References to 1994, 1993, and 1992 are for the fiscal years ended
 December 31, 1994, January 1, 1994, and January 2, 1993, respectively.
 Fiscal years 1994 and 1993 each included 52 weeks; 1992 included 53 weeks.

 Revenue Recognition
 For substantially all of its operations, 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.
 Revenues and profits on substantially all contracts are recognized using
 the percentage-of-completion method. Revenues recorded under the
 percentage-of-completion method were $15,421,000 in 1994, $23,218,000 in
 1993, and $27,448,000 in 1992. Revenues earned on contracts in process in
 excess of billings are classified as "Unbilled contract costs and fees" in
 the accompanying balance sheet. There are no significant amounts included
 in the accompanying balance sheet that are not expected to be recovered
 from existing contracts at current contract values, or that are not
 expected to be collected within one year, including amounts that are billed
 but not paid under retainage provisions.

 Gain on Issuance of Stock by Subsidiary
 At the time a subsidiary sells its stock to third parties at a price in
 excess of its book value, the Company's net investment in that subsidiary
 increases. If at that time the subsidiary is an operating entity and not
 engaged principally in research and development, the Company records the
 increase as a gain.

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

 Income Taxes
 The Company and Thermo Electron have a tax allocation agreement under which
 the Company is included in the consolidated federal and state income tax
 returns filed by Thermo Electron. The agreement provides that in years in
 which the Company has taxable income, it will pay to Thermo Electron

                                      10PAGE
<PAGE>
 Thermo Instrument Systems Inc.


 amounts comparable to the taxes the Company would have paid if it had filed
 separate tax returns. In years in which the Company incurs a loss, Thermo
 Electron will reimburse the Company the amount the Company would have
 received if it had filed separate tax returns. If Thermo Electron's equity
 ownership of the Company were to drop below 80%, the Company would be
 required to file its own income tax returns. As of December 31, 1994, the
 Company owed $11,275,000 to Thermo Electron for estimated federal and state
 income tax payments. This amount is included in "Accrued income taxes" in
 the accompanying 1994 balance sheet.

 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
 Primary earnings per share have been computed based on the weighted average
 number of shares outstanding during the year. Because the effect of the
 exercise of stock options would be immaterial, they have been excluded from
 the primary earnings per share calculation. Fully diluted earnings per
 share assumes the exercise of stock options and conversion of the Company's
 dilutive convertible obligations and elimination of the related interest
 expense.

 Stock Split
 All share and per share information was restated in 1993 to reflect a
 three-for-two stock split, effected in the form of a 50% stock dividend,
 which was distributed in July 1993.

 Cash and Cash Equivalents
 As of December 31, 1994, $65,955,000 of the Company's cash equivalents were
 invested in a repurchase agreement with Thermo Electron. Under this
 agreement, the Company in effect lends excess cash to Thermo Electron,
 which Thermo Electron collateralizes with investments principally
 consisting of corporate notes, U.S. government agency securities, money
 market funds, commercial paper, and other marketable securities, in the
 amount of at least 103% of such obligation. The Company's funds subject to
 the repurchase agreement are readily convertible into cash by the Company
 and have an original maturity of three months or less. The repurchase
 agreement earns a rate based on the Commercial Paper Composite Rate plus 25
 basis points, set at the beginning of each quarter. As of December 31,
 1994, the Company's cash equivalents also include investments in short-term
 certificates of deposit of the Company's foreign subsidiaries, which have
 an original maturity of three months or less. Cash and cash equivalents are
 carried at cost, which equals fair market value at year-end 1994 and 1993.

 Available-for-sale Investments
 Pursuant to SFAS No. 115, "Accounting for Certain Investments in Debt and
 Equity Securities," effective January 2, 1994, the Company's debt and
 marketable equity securities are accounted for at market value (Note 2).
 Prior to 1994, these investments were carried at the lower of cost or
 market value. The fair market value of investments is determined based on
 quoted market prices for those investments.

 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 -- 20 to 40
 years, machinery and equipment -- 3 to 10 years, and leasehold improvements
 -- the shorter of the term of the lease or the life of the asset. Property,
 plant and equipment consist of the following:

 Patents and Other Assets
 "Patents and other assets" in the accompanying balance sheet includes the
 costs of acquired trademarks, patents, and other specifically identifiable
 intangible assets. These assets are amortized using the straight-line
 method over their estimated useful lives, which range from 4 to 15 years.
 These assets were $17,032,000 and $18,056,000, net of accumulated
 amortization of $10,501,000 and $7,937,000, at year-end 1994 and 1993,
 respectively.

 Cost in Excess of Net Assets of Acquired Companies
 The excess of cost over the fair value of net assets of acquired businesses
 is amortized using the straight-line method over 40 years. Accumulated
 amortization was $28,245,000 and $19,780,000 at year-end 1994 and 1993,
 respectively. The Company assesses the future useful life of this asset
 whenever events or changes in circumstances indicate that the current
 useful life has diminished. The Company considers the future undiscounted
 cash flows of the acquired businesses in assessing the recoverability of
 this asset.

 Foreign Currency
 All assets and liabilities of the Company's foreign subsidiaries are
 translated at year-end exchange rates, and revenues and expenses are
 translated at average exchange rates for the year in accordance with SFAS

 No. 52, "Foreign Currency Translation." Resulting translation adjustments
 are reflected as a separate component of shareholders' investment titled
 "Cumulative translation adjustment." Foreign currency transaction gains and
 losses are included in the accompanying statement of income and are not
 material for the three years presented.

 Presentation
 Certain amounts in 1993 and 1992 have been reclassified to conform to the
 1994 financial statement presentation.


 2.   Available-for-sale Investments

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

 Available-for-sale investments in the accompanying 1994 balance sheet
 represent investments in corporate bonds of $13,027,000 with contractual
 maturities of one year or less and $2,904,000 with contractual maturities
 of more than one year through five years. Actual maturities may differ from
 contractual maturities as a result of the Company's intent to sell these
 securities prior to maturity and as a result of put and call options that
 enable either the Company and/or the issuer to redeem these securities at
 an earlier date. The difference between the market value and the cost basis
 of available-for-sale investments at December 31, 1994, was $546,000, which
 represents gross unrealized gains of $607,000 and gross unrealized losses
 of $61,000 on those investments.

 The cost of available-for-sale investments that were sold was based on
 specific identification in determining realized gains recorded in the
 accompanying statement of income. Gain on sale of investments in 1994
 resulted from gross realized gains relating to the sale of available-for-
 sale investments.


 3.   Joint Venture

 Effective April 4, 1994, the Company formed an environmental services joint
 venture with Thermo Process Systems Inc. (Thermo Process), another public
 subsidiary of Thermo Electron. The joint venture operates under the name
 Thermo Terra Tech. The Company contributed the analytical laboratories and
 the nuclear health physics and environmental science and engineering
 services businesses that comprised its Services segment. Thermo Process
 contributed its environmental laboratory business, which specializes in
 fast-response testing of petroleum-contaminated soils and groundwater, and
 approximately $31 million in cash and short-term investments.

 The Company owns 49% of Thermo Terra Tech and accounts for its interest in
 the joint venture using the equity method. Under the terms of the joint

 venture agreement, 66.67% of income earned by the joint venture after April
 4, 1994, will be allocated to the Company until the first to occur of (a)
 the joint venture has accumulated $5.1 million in net profits, (b) April 1,
 1995, or (c) the date on which at least 70% of Thermo Process' cash
 contribution to the joint venture is first invested in one or more
 additional businesses. Thereafter, the Company's share of the joint
 venture's income will be 49%. The Company recorded $2,965,000 of income in
 1994 related to its investment in Thermo Terra Tech, which is included in
 "Equity in income of unconsolidated subsidiaries, net" in the accompanying
 statement of income.


 4.   Acquisitions and Disposition

 In March 1994, the Company acquired several businesses within the
 EnviroTech Measurements & Controls group of Baker Hughes Incorporated
 (Baker Hughes) for a purchase price of $89.7 million in cash. The Company
 acquired the EnviroTech Controls, NORAN Instruments (NORAN), TN
 Technologies, and Tremetrics businesses, which collectively design,
 manufacture, and market a variety of process control, process measurement,
 and laboratory analytical products for use in a wide range of industrial,
 energy, environmental, and research applications. The Company contributed
 the assets acquired and liabilities assumed from NORAN to the Company's
 ThermoSpectra subsidiary. During 1994, the Company made several other
 acquisitions for an aggregate $11.2 million in cash.

 In February 1993, the Company acquired Spectra-Physics Analytical, a
 manufacturer of liquid chromatography and capillary electrophoresis
 analytical instruments, for $67.3 million in cash. The Company funded the
 acquisition of Spectra-Physics Analytical through the issuance of a $69
 million promissory note to Thermo Electron that was repaid in May 1993.
 During 1993, the Company made several other acquisitions for an aggregate
 $35.6 million in cash. The Company funded these acquisitions through the
 issuance of a $20 million promissory note to Thermo Electron that was
 repaid in 1993, and through short-term borrowings from Thermo Electron.

 These acquisitions have been accounted for using the purchase method of
 accounting, and their results of operations have been included in the
 accompanying financial statements from their respective dates of
 acquisition. The aggregate cost of these acquisitions exceeded the
 estimated fair value of the acquired net assets by approximately $111
 million, which is being amortized over 40 years. Allocation of the purchase
 price for these acquisitions was based on estimates of the fair value of
 the net assets acquired and, for acquisitions completed in fiscal 1994, is
 subject to adjustment.

 Effective April 5, 1993, the Company sold the biomedical instruments
 products business of its Nicolet Instrument Corporation subsidiary (Nicolet
 Biomedical) to Thermo Electron for $67.9 million in cash. The results of
 operations of Nicolet Biomedical have been excluded from the accompanying
 financial statements as of April 5, 1993.

 Based on unaudited data, the following table presents selected financial
 information for the Company (excluding Nicolet Biomedical), the EnviroTech
 Measurements & Controls group of Baker Hughes, and Spectra-Physics
 Analytical on a pro forma basis, assuming the companies had been combined
 since the beginning of 1993. The effect on the Company's financial

 The pro forma information includes the historical results for the
 environmental services businesses that comprised the Company's Services
 segment (Note 3). The pro forma results are not necessarily indicative of
 future operations or the actual results that would have occurred had the
 acquisitions been made at the beginning of 1993.

 "Effect of purchase of Nicolet shares from parent company" in the
 accompanying statement of shareholders' investment represents the
 difference between the purchase price of Nicolet Instrument Corporation
 (Nicolet) shares that were acquired by Thermo Electron in the open market
 prior to the Company's tender offer of Nicolet in 1992 and the cash tender
 offer price. Due to the related party nature of this purchase from Thermo
 Electron, the excess of the purchase price paid by the Company over the
 original purchase price paid by Thermo Electron was reflected as a
 reduction in retained earnings. "Effect of sale of Nicolet Biomedical" in
 the accompanying statement of shareholders' investment represents the
 portion that relates to Nicolet Biomedical.

 "Other accrued expenses" in the accompanying balance sheet includes
 approximately $17 million and $25 million at year-end 1994 and 1993,
 respectively, for estimated severance, relocation, and other reserves
 associated with acquisitions.


 5.   Stock-based Compensation Plans

 The Company has stock-based compensation plans for its key employees,
 directors, and others. Two of these plans, adopted in 1986, permit the
 grant of nonqualified and incentive stock options. A third plan, adopted in
 1993, 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 these plans. The option recipients
 and the terms of options granted under these plans are determined by the
 Board Committee. Generally, options granted to date are exercisable
 immediately, but are subject to certain transfer restrictions and the right
 of the Company to repurchase shares issued upon exercise of the options at
 the exercise price, upon certain events. The restrictions and repurchase
 rights generally lapse ratably over periods ranging from four to ten years
 after the first anniversary of the grant date, depending on the term of the
 option, which may range from five to twelve years. Nonqualified stock
 options may be granted at any price determined by the Board Committee,
 although incentive stock options must be granted at not less than fair
 market value of the Company's stock on the date of grant. Generally, all
 options have been granted at fair market value. The Company also has a
 directors' stock option plan, adopted in 1991, that provides for the grant

                                      15PAGE
<PAGE>
 Thermo Instrument Systems Inc.


 of stock options to nonemployee directors pursuant to a formula approved by
 the Company's shareholders. Options awarded under this plan are exercisable
 six months after the date of grant and expire three or seven years after
 the date of grant. In addition to the Company's stock-based compensation
 plans, certain officers and key employees may also participate in the
 stock-based compensation plans of Thermo Electron or its majority-owned
 subsidiaries.

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

 6.  Common Stock

 At December 31, 1994, the Company had reserved 12,341,714 unissued shares
 of its common stock for possible issuance under stock-based compensation
 plans and for issuance upon possible conversion of the Company's
 convertible obligations.


 7.  Employee Benefit Plans

 Employee Stock Purchase Plan
 Substantially all of the Company's full-time U.S. employees are eligible to
 participate in an employee stock purchase plan sponsored by the Company.
 Under this plan, shares of the Company's and Thermo Electron's common stock
 may be purchased at the end of a 12-month plan year at 85% of the fair
 market value at the beginning of the plan year, and the shares purchased
 are subject to a one-year resale restriction. Shares are purchased through
 payroll deductions of up to 10% of each participating employee's gross
                                      16PAGE

 wages. During 1994, 1993, and 1992, the Company issued 51,800 shares,
 101,273 shares, and 66,426 shares of its common stock, respectively, under
 this plan.

 401(k) Savings Plan and Employee Stock Ownership Plan
 The majority of the Company's full-time U.S. employees are eligible to
 participate in Thermo Electron's 401(k) savings plan and employee stock
 ownership plan. Contributions to the 401(k) savings plan are made by both
 the employee and the Company. Company contributions are based upon the
 level of employee contributions. For these plans, the Company contributed
 and charged to expense $2,774,000, $2,239,000, and $1,728,000 in 1994,
 1993, and 1992, respectively.

 Postemployment Benefits
 The Company provides certain postemployment benefits to former or inactive
 employees. Effective January 2 1994, the Company adopted  SFAS No. 112,
 "Employers' Accounting for Postemployment Benefits." SFAS No. 112 requires
 the recognition of the cost of postemployment benefits if certain criteria
 are met and the amount of benefits can be reasonably estimated. The
 adoption of this statement did not have a material impact on the Company's
 financial statements.

 The provision for income taxes that is currently payable does not reflect
 $1,120,000, $1,815,000, and $1,631,000 of tax benefits allocated to
 "Capital in excess of par value" in 1994, 1993, and 1992, respectively, or
 $1,150,000 and $3,060,000 of tax benefits used to reduce "Cost in excess of
 net assets of acquired companies" in 1993 and 1992, respectively.

 "Provision for income taxes" in the accompanying statement of income
 differs from the provision calculated by applying the statutory federal
 income tax rate of 35% in 1994 and 1993 and 34% in 1992 to income before
 provision for income taxes and minority interest expense due to the

 assets and $2,375,000 for federal net operating loss and tax credit
 carryforwards, the realization of which is limited to the future income of
 certain subsidiaries. The net operating loss and tax credit carryforwards
 expire in the years 2002 through 2005, and the resulting benefit will be
 used to reduce "Cost in excess of net assets of acquired companies."

 A provision has not been made for U.S. or additional foreign taxes on $39
 million of undistributed earnings of foreign subsidiaries that could be
 subject to taxation if remitted to the U.S. because the Company plans to
 keep these amounts permanently reinvested overseas. The Company believes
 that any additional U.S. tax liability due upon remittance of such earnings
 would be immaterial due to available U.S. foreign tax credits.


 9.   Commitments and Contingencies

 Operating Leases
 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 $9,028,000, $8,172,000, and
 $5,893,000 in 1994, 1993, and 1992, respectively. Future minimum payments
 due under noncancellable operating leases at December 31, 1994, are
 $7,791,000 in 1995; $6,136,000 in 1996; $4,581,000 in 1997; $3,668,000 in
 1998; $2,673,000 in 1999; and $10,159,000 in 2000 and thereafter. Total
 future minimum lease payments are $35,008,000.

 Litigation
 The Company is contingently liable with respect to lawsuits and other
 matters that arose in the ordinary course of business. In the opinion of
 management, these contingencies will not have a material effect upon the
 financial position of the Company or its results of operations.


 10.  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 1.25% of the Company's revenues in fiscal 1994 and 1993. Prior to
 1993, the Company paid an annual fee equal to 1% of the Company's revenues.
 Beginning in fiscal 1995, the Company will pay an annual fee equal to 1.20%
 of the Company's revenues. The annual fee is reviewed and adjusted annually
 by mutual agreement of the parties. For these services, the Company was
 charged $8,277,000, $7,302,000, and $4,232,000 in 1994, 1993, and 1992,
 respectively. Management believes that the service fee charged by Thermo
 Electron is reasonable and that such fees are representative of the
 expenses the Company would have incurred on a stand-alone basis. The
 corporate services agreement is renewed annually but can be terminated upon
 30 days' prior notice by the Company or upon the Company's withdrawal from
 the Thermo Electron Corporate Charter (the Thermo Electron Corporate
 Charter defines the relationship among Thermo Electron and its
 majority-owned subsidiaries). For additional items such as employee benefit
 plans, insurance coverage, and other identifiable costs, Thermo Electron
 charges the Company based upon costs attributable to the Company.

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

 Short-term Investments
 At December 31, 1994, the Company's available-for-sale investments included
 $2,904,000 (amortized cost of $2,298,000) of 6 1/2% subordinated
 convertible debentures due 1998, which were purchased on the open market
 for $2,297,000. The debentures have a par value of $2,323,000 and were
 issued by Thermedics Inc. (Thermedics), which is a majority-owned
 subsidiary of Thermo Electron, and are guaranteed on a subordinated basis
 by Thermo Electron. During 1994, the Company sold $4,000,000 par value of
 the Thermedics debentures for net proceeds of $5,890,000, which resulted in
 a gain of $2,000,000.

 14.  Subsequent Events

 Potential Acquisition
 On March 1, 1995, the Company entered into an Asset and Stock Purchase
 Agreement (the Agreement) with Fisons plc (Fisons) under which the Company
 agreed to acquire the Scientific Instruments Division (the Division) of
 Fisons for 202 million British pounds sterling. The Division is principally
 composed of operations that are involved in the research, development,
 manufacture, and sale of analytical instruments to industrial and research
 laboratories worldwide. For the fiscal year ended December 31, 1994, the
 Division had unaudited revenues of approximately 262 million British pounds
 sterling and an unaudited net loss of approximately 19 million British
 pounds sterling. Consummation of the acquisition is subject to several
 conditions, including approval by Fisons shareholders, regulatory
 approvals, consent of certain third parties, and customary conditions to
 closing. The Company intends to fund the purchase price from available cash
 and through borrowings from Thermo Electron. Thermo Electron has guaranteed
 the obligations of the Company under the Agreement. The purchase price is
 subject to a post-closing adjustment based on the net asset value of the
 Division as of the closing date.

 Report of Independent Public Accountants
 --------------------------------------------------------------------------

 To the Shareholders and Board of Directors
 of Thermo Instrument Systems Inc.:

 We have audited the accompanying consolidated balance sheets of Thermo
 Instrument Systems Inc. (a Delaware corporation and 83%-owned subsidiary of
 Thermo Electron Corporation) and subsidiaries as of December 31, 1994 and
 January 1, 1994, and the related consolidated statements of income,
 shareholders' investment, and cash flows for each of the three years in the
 period ended December 31, 1994. These consolidated financial statements are
 the responsibility of the Company's management. Our responsibility is to
 express an opinion on these consolidated financial statements based on our
 audits.

 We conducted our audits in accordance with generally accepted auditing
 standards. Those standards require that we plan and perform the audit to
 obtain reasonable assurance about whether the 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
 Instrument Systems Inc. and subsidiaries as of December 31, 1994 and
 January 1, 1994, and the results of their operations and their cash flows
 for each of the three years in the period ended December 31, 1994, in
 conformity with generally accepted accounting principles.

 As discussed in Note 2 to the consolidated financial statements, effective
 January 2, 1994, the Company changed its method of accounting for

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

 Results of Operations

 The Company's revenues were $662.2 million in 1994, compared with $584.2
 million in 1993 and $423.2 million in 1992. Instruments segment revenues
 increased 23% to $650.1 million in 1994, compared with the 44% increase
 reported in 1993. The increase was due to acquisitions, which added
 revenues of approximately $125 million in 1994 and $147 million in 1993.
 The Company's acquisitions included several businesses within the
 EnviroTech Measurements & Controls group of Baker Hughes Incorporated
 (Baker Hughes) in March 1994, the radiation safety measurement products and
 radiometry process control divisions of FAG Kugelfischer Georg Shafer AG in
 October 1993, Spectra-Physics Analytical in February 1993, and
 Gamma-Metrics in January 1993. The 1993 and 1992 results included $12.6
 million and $20.2 million, respectively, in revenues from the biomedical
 instruments products business of the Company's Nicolet Instrument
 Corporation subsidiary (Nicolet Biomedical), which was sold to Thermo
 Electron Corporation (Thermo Electron) effective April 5, 1993. Services
 segment revenues were $12.2 million for the three-month period ended April
 2, 1994, $55.2 million in 1993, and $54.9 million in 1992. Effective April
 4, 1994, the Company contributed the businesses that comprised its Services
 segment to Thermo Terra Tech in exchange for a 49% ownership interest in
 that joint venture. As a result, the Services segment operations are no
 longer consolidated in the Company's financial statements (see Note 3 to
 Consolidated Financial Statements).

 The gross profit margin increased to 48% in 1994 from 47% in 1993 and 45%
 in 1992. The increase in 1994 reflects the transfer of the lower-margin
 businesses that comprised the Company's Services segment to the Thermo
 Terra Tech joint venture as discussed above. The gross profit margin for
 the Instruments segment remained relatively unchanged at 48% in 1994 and
 49% in both 1993 and 1992. The gross profit margin for the Services segment
 decreased one percentage point in 1994 to 22% and improved three percentage
 points in 1993. The improvement in 1993 was due to cost reductions in the
 Company's engineering services business and greater revenues contributed by
 the higher-margin environmental laboratory and infrastructure business.

 Selling, general and administrative expenses as a percentage of revenues
 increased to 26.6% in 1994 from 25.4% in 1993, and 25.1% in 1992. The
 increases resulted primarily from higher costs as a percentage of revenues
 at acquired businesses.

 Research and development expenses were 6.6% of Instruments segment revenues
 in 1994, compared with 6.5% in 1993 and 7.1% in 1992. Research and
 development expenses declined in 1993 primarily due to the Company's
 completion of the development of its Magna-IR (TM) and Quantum (TM)
 products, which were introduced by the Company's Nicolet and Finnigan
 subsidiaries, respectively.

 Interest income was $5.9 million in 1994, $3.6 million in 1993, and $7.0
 million in 1992. The increase in 1994 was primarily a result of interest
 income earned on the net proceeds from the issuance of 3 3/4% senior

 convertible obligations in September 1993, offset in part by the cash used
 to purchase several businesses within the EnviroTech Measurements &
 Controls group of Baker Hughes in the first quarter of 1994. The decrease
 in 1993 was primarily a result of lower average balances of short-term
 investments due to the cash expended for the acquisition of Nicolet
 Instrument Corporation in August 1992, offset in part by interest income
 earned on the net proceeds from the issuance of the 3 3/4% senior
 convertible obligations in September 1993. Interest expense increased to
 $15.8 million in 1994 from $14.4 million in 1993 and $11.4 million in 1992
 due primarily to the issuance of the 3 3/4% senior convertible obligations
 in September 1993, offset in part by a reduction in interest expense as a
 result of the repayment in the third quarter of 1993 of debt incurred in
 connection with acquisitions.

 As a result of the sale of stock by its ThermoSpectra Corporation
 subsidiary (ThermoSpectra), the Company recorded a gain of $6.5 million in
 1994. The gain represents an increase in the Company's proportionate share
 of the subsidiary's equity and is classified as "Gain of issuance of stock
 by subsidiary" in the accompanying 1994 statement of income. "Gain on sale
 of investments" in the accompanying 1994 statement of income resulted from
 the sale of a portion of the Company's investment in Thermedics Inc.
 (Thermedics) convertible debentures. Thermedics is a majority-owned
 subsidiary of Thermo Electron. "Gain on sale of investments" in the
 accompanying 1992 statement of income resulted from the partial liquidation
 of the Company's short-term investments. The proceeds from the sale of the
 short-term investments were used to reduce borrowings from Thermo Electron.

 "Equity in income of unconsolidated subsidiaries, net" in 1994 primarily
 represents the Company's portion of the results of Thermo Terra Tech (see
 Note 3 to Consolidated Financial Statements).

 The effective tax rate was 39% in 1994, 43% in 1993, and 42% in 1992. These
 rates exceeded the statutory federal income tax rate primarily due to
 nondeductible amortization of cost in excess of net assets of acquired
 companies, the inability to provide a tax benefit on losses incurred at
 certain foreign subsidiaries, and the impact of state income taxes. The
 effective tax rate decreased in 1994 from 1993 due primarily to the
 nontaxable gain on the issuance of stock by the Company's ThermoSpectra
 subsidiary.

 Net income increased 35% in 1994 to a record $60.2 million, following a 35%
 increase in 1993. Primary earnings per share grew 28% to $1.28 in 1994,
 compared with a 30% increase in 1993.

 Liquidity and Capital Resources

 Consolidated working capital at December 31, 1994, was $230.3 million,
 compared with $238.1 million at January 1, 1994, a decrease of $7.8
 million. Included in working capital are cash, cash equivalents, and
 short-term investments of $168.9 million at December 31, 1994, and $183.6
 million at January 1, 1994. Of the $168.9 million balance at December 31,
 1994, $19.3 million was held by the Company's ThermoSpectra subsidiary and
 $149.6 million by the Company and its wholly owned subsidiaries. Cash
 provided by operations in 1994 was $80.8 million. During 1994, the Company
 expended $100.9 million for acquisitions. In 1994, the Company's
 ThermoSpectra subsidiary sold 1,505,000 shares of its common stock in
 private placements for net proceeds of $14.0 million.

 In 1995, the Company plans to make expenditures for property, plant and
 equipment of approximately $11 million. The Company plans to make these
 expenditures from working capital. The Company believes that its existing
 resources are sufficient to meet the capital requirements of its existing
 operations for the foreseeable future.

 The Company has historically complemented internal development with
 acquisitions of businesses or technologies that extend the Company's
 presence in current markets or provide opportunities to enter and compete
 effectively in new markets. The Company will consider making acquisitions
 of such companies, product lines, or technologies that are consistent with
 its plans for strategic growth. On March 1, 1995, the Company entered into
 an agreement to acquire the Scientific Instruments Division of Fisons plc
 for 202 million British pounds sterling, subject to a post-closing
 adjustment. The purchase price will be funded from available cash and
 through borrowings from Thermo Electron (see Note 14 to Consolidated
 Financial Statements).
