   Item 1. Business

   (a)  General Development of Business.

        Thermo Cardiosystems Inc. (the Company or the Registrant) is a leader
   in the research, development, and manufacture of implantable left
   ventricular-assist systems (LVAS). These systems are designed to perform
   substantially all or part of the pumping function of the left ventricle of
   the natural heart for patients suffering from cardiovascular disease.
   Unlike total artificial heart systems, which require removal of the natural
   heart, the LVAS allows the natural heart to remain in place, preserving the
   heart's biological control mechanisms and reducing blood-contacting
   surfaces that have led to strokes in patients using other cardiac devices.
   The Company has developed two systems for patients requiring long-term
   cardiac support: an implantable pneumatic (IP) LVAS that is powered by an
   external electrically driven air-pump, and an electric LVAS that is driven
   by an implanted electric motor and powered by a lightweight battery pack
   worn by the patient. In October 1994, the Company announced that the U.S.
   Food and Drug Administration (FDA) had granted approval for the commercial
   sale of the air-driven LVAS for use as a bridge-to-transplant. With this
   approval, the air-driven system became available for sale to cardiac
   centers throughout the United States. The Company received the European
   Conformity Mark (CE Mark) for commercial sale of the air-driven LVAS in all
   European Community countries in April 1994, and, in August 1995, received
   the same approval for the electric system. The electric version of the LVAS
   is currently being used in the U.S. in clinical trials for patients
   awaiting heart transplants, and, late in 1995, the FDA approved the
   protocol for conducting clinical trials of the electric LVAS as an
   alternative to heart transplant. The electric LVAS is being used in Europe
   as both a bridge-to-transplant and as an alternative to heart transplant.

        The Company was incorporated in 1988 as a wholly owned subsidiary of
   Thermedics Inc. (Thermedics), and is the successor in interest to the
   assets and business of that company relating to the research and
   development of implantable heart-assist systems. This business was
   conducted by Thermedics from its formation in 1983, and prior to that time
   as a division of Thermo Electron Corporation (Thermo Electron) beginning in
   1966. As of December 30, 1995, Thermedics owned 12,525,110 shares of the
   Company's common stock, representing 52% of such stock outstanding. A
   publicly traded subsidiary of Thermo Electron, Thermedics develops,
   manufactures, and markets process detection and security instruments,
   electronic test instruments, and biomedical products. As of December 30,
   1995, Thermo Electron owned 659,967 shares of the Company's common stock,
   representing 3% of such stock outstanding. In January 1996, Thermedics
   acquired 529,965 shares of the Company's common stock from Thermo Electron.
   In consideration for such shares, and 315,199 shares of the common stock of
   Thermo Voltek Corp., another subsidiary of Thermedics, Thermedics issued
   1,688,161 shares of its common stock to Thermo Electron. The shares of
   common stock were exchanged their respective at fair market values on the
   date of the transaction. Thermedics is a 51%-owned subsidiary of Thermo
   Electron. Thermo Electron is a world leader in environmental monitoring and
   analysis instruments and a manufacturer of biomedical products including
   mammography systems, paper-recycling and papermaking equipment,
   alternative-energy systems, industrial process equipment, and other 

                                        2PAGE
<PAGE>
   specialized products. Thermo Electron also provides environmental and
   metallurgical services and conducts advanced technology research and
   development.
        Thermedics intends for the foreseeable future to maintain at least 50%
   ownership of the Company. This may require the purchase by Thermedics of
   additional shares of common stock of the Company from time to time as the
   number of outstanding shares issued by the Company increases. These or any
   other purchases by Thermedics may be made either in the open market or
   directly from the Company or Thermo Electron. See Notes 3 and 6 to
   Financial Statements in the Company's 1995 Annual Report to Shareholders
   for a description of outstanding stock options and convertible obligations
   issued by the Company. 

   (b)  Financial Information About Industry Segments.

        The Company conducts business in one industry segment: the research,
   development, and manufacture of implantable heart-assist systems.

   (c)  Description of Business.

        (i) Principal Products and Services

   Left Ventricular-Assist Systems

        The Company has developed two versions of its LVAS -- an implantable
   pneumatic, or air-driven system that can be controlled by either a bedside
   or portable console and an electric system that features an internal
   electric motor powered by an external battery pack worn by the patient.
   Both of the Company's systems employ the Company's HeartMate(R) blood pump,
   and are designed for long-term use.

        The Company's blood pump incorporates proprietary technological
   advances in biological compatibility that distinguish it from competitive
   devices, including proprietary textured linings that significantly reduce
   the likelihood of blood clots that can lead to strokes. The Company
   believes that the smooth-surface linings used in other cardiac devices have
   led to increased incidences of blood clots. The Company's systems are
   designed to enhance patients' quality of life by allowing them to become
   ambulatory and resume functioning in society.

        The Company's LVAS devices are at various stages of regulatory
   approval (see "The Company's LVAS Devices").

   Product Background

        The Company began its research and development work in cardiac-support
   systems in 1966. Since that time, the Company and its predecessors have
   received more than $37 million in funding from the U.S. government,
   principally from the National Heart, Lung, and Blood Institute of the
   National Institutes of Health (NIH), to support its research. This funding
   ended in 1992 as the Company moved from development to clinical trials.

        Federal regulations require that the Company obtain an investigational
   device exemption (IDE) from the U.S. Food and Drug Administration (FDA) to
   conduct testing in humans. Once sufficient testing has been completed to
   demonstrate the safety and effectiveness of the LVAS, the Company submits a
   premarket approval (PMA) application to the FDA. PMA supplements must be 

                                        3PAGE
<PAGE>
   submitted for each type and application of the Company's LVAS before being
   sold commercially (see "Government Regulation").

   The Company's LVAS Devices

        The human heart contains two main pumping chambers: the left and right
   ventricles. The right ventricle pumps blood into the lungs where it is
   oxygenated. The blood then flows into the left ventricle where it is pumped
   throughout the body. The Company's LVAS devices support all or part of the
   pumping function of the left ventricle.

        An LVAS provides many advantages over total artificial hearts. Unlike
   a total artificial heart system, an LVAS allows the natural heart to be
   left in place and assists the heart when it is unable to provide sufficient
   cardiac function to maintain life. This approach provides the advantage of
   leaving in place certain biological control mechanisms, such as blood flow
   regulation and the production of certain peptides that regulate blood
   volume. Retention of the natural heart also provides the important
   psychological advantage of not removing the organ. In addition, an LVAS has
   fewer blood-contacting surfaces and valves than artificial hearts, and
   therefore is less likely to cause blood damage that can lead to blood clots
   and strokes.

        Each version of the Company's LVAS incorporates a number of
   proprietary technological advances in biological compatibility that
   distinguish it from other cardiac-assist devices. For example, the
   Company's systems employ proprietary textured linings that significantly
   reduce the likelihood of blood clots that can lead to strokes. As blood
   enters the pump chamber, blood elements are trapped by its textured
   surface, forming a coagulum, or lining. This coagulum is securely anchored
   to the textured surface and forms a "living" lining similar to that found
   in arteries and veins. This blood-contacting surface is derived from the
   patient's own blood and is therefore blood-compatible. Data from the
   Company's clinical studies indicate that use of either of the Company's
   LVAS devices can result in a significant reduction in the need for
   anticoagulants and a reduction in the risk of blood clots, due to the
   Company's use of unique textured blood-contacting surfaces. Because of the
   risk of blood clots, patients who receive smooth-surface devices must take
   daily doses of anticoagulants, the level of which must be constantly
   monitored. In contrast, patients on the Company's LVAS receive only minimal
   anticoagulation treatment.

        The HeartMate blood pump is used in each version of the Company's
   LVAS. This pump is implanted just below the diaphragm in a position that
   minimizes interference with normal circulation and other bodily functions.
   An inlet tube is inserted into the apex of the left ventricle to drain
   blood into the pump chamber. Blood is then forced out of the pump through
   an animal tissue valve and back into the aorta. The HeartMate blood pump
   works with the biological control mechanism of the natural heart to
   increase pumping capability when required for activities such as climbing
   stairs.

        IP LVAS. The Company announced in October 1994, that the air-driven
   system had been approved for commercial sale by the FDA. This approval
   allows the Company to sell the IP LVAS to any of the nearly 900 cardiac
                                        4PAGE
<PAGE>
   surgery centers in the United States. In April 1994, the Company received
   the CE Mark for commercial sale of the air-driven LVAS in all European
   Community countries. This system is intended as a bridge-to-transplant for
   patients awaiting heart transplantation. In the IP LVAS, the HeartMate
   blood pump is coupled to an external console connected to the body by a
   tube. The Company has also developed the HeartPak (TM), a lightweight
   portable console that can be carried over the shoulder. The portable
   console received the CE Mark for commercial sale in European Community
   countries in February 1995. In July 1995, the FDA approved the beginning of
   Phase I clinical trials of the HeartPak portable pneumatic driver. Phase I
   of the study will evaluate the safety of the system in the hospital; Phase
   II will evaluate the system in the home environment.

        To date, more than 500 patients have been supported by the IP LVAS
   prior to transplantation, including one patient who was supported for 390
   days. There are currently approximately 60 cardiac surgery centers in the
   United States that offer patients the Company's IP LVAS. These include
   leading transplant centers, such as the Texas Heart Institute at Saint
   Luke's Episcopal Hospital, The Cleveland Clinic Foundation,
   Columbia-Presbyterian Medical Center, and Sharp Memorial Hospital of San
   Diego. In addition, the Company is working with nearly 30 sites in such
   countries as the United Kingdom, Germany, Sweden, Japan, the Netherlands,
   France, Italy, and Belgium.

        Electric LVAS. The Company has also developed an electric LVAS that
   uses the HeartMate blood pump driven by an internal electric motor mounted
   in the blood pump housing. The system is connected to its external battery
   pack by wires that exit the body. Since the power source and control
   elements are worn on a battery belt, the system allows the patient complete
   mobility. 

        In early 1991, the Company received an IDE from the FDA allowing the
   Company to begin clinical studies of the electric LVAS. This IDE is being
   restructured as a two-phase study to evaluate the electric system for
   safety in the hospital and home environment. The efficacy of the HeartMate
   blood-contacting components, common to both the air-driven and electric
   devices, has already been established, thereby reducing the complexity
   level for testing of the Company's electric LVAS. To date, 18 clinical
   sites have been approved by the FDA and more than 70 implants have been
   performed, including one implant that supported a patient for 416 days
   prior to transplant. In October 1991, the FDA granted approval for patients
   at the Texas Heart Institute supported by the electric LVAS to take
   day-trips away from the hospital, marking the first time that patients with
   a cardiac-assist device could leave a controlled medical environment. In
   April 1993, this approval was extended by the FDA to allow patients to be
   discharged from the hospital with their physician's approval. Discharge
   from the hospital improves the quality of life for patients with an LVAS
   and reduces the substantial costs associated with extended hospital stays.
   The electric LVAS may not be sold commercially in the U.S. until it has
   received approval from the FDA. In December 1995, the FDA approved the
   protocol for conducting clinical trials of the electric LVAS as an
   alternative to heart transplant. The trial is expected to compare the
   results of approved patients using the device to a similar number using
   drug therapy. In August 1995, the electric LVAS was awarded the CE Mark,
   allowing commercial sale of this system in all European Community
   countries. The electric system is used as a bridge-to-transplant in the
   U.S. and Europe, and is also implanted as an alternative to heart
   transplant in Europe.
                                        5PAGE

   Development Program

        The Company believes that commercial use of the air-driven system --
   and development of the electric system currently under clinical study --
   will provide a substantial technical basis for clinical testing of
   subsequent LVAS devices. For example, the Company plans to develop smaller
   air-driven systems for smaller patients who do not require the same blood
   flow provided by current systems. The principal engineering task in
   developing a small system is the miniaturization of the pump in a manner
   that preserves biocompatibility.

   Transplant Centers Development and Training

        Transplant centers provide a nationwide heart transplant capability
   far in excess of the number of donor hearts available and represent the
   principal target for use of the Company's LVAS systems. The cardiac
   surgeons affiliated with these transplant centers are opinion leaders who
   strongly influence the cardiac care that patients receive and, therefore,
   will have an important impact on the market for the Company's systems. The
   Company has developed working relationships with a number of leading
   cardiac surgery centers, and has received significant support among opinion
   leaders in cardiac surgery and cardiology.

        The Company estimates that new customer transplant centers can be
   developed, and physicians can be trained, in approximately three months.
   For each initial sale -- known as an implementation program -- the Company
   receives a one-time fee from the transplant center for training expenses,
   as well as for pumps, consoles, and related equipment used by the center.
   Subsequent implants consist of sales to an existing customer other than the
   initial sale of the implementation program.

   Government Regulation

        The Company's LVAS is classified as a Class III medical device under
   the Federal Food, Drug and Cosmetic Act. The first stage of obtaining
   formal FDA market approval for a Class III device is submission of an
   application for an IDE. The IDE permits clinical evaluations of significant
   risk devices on human subjects under controlled experimental conditions by
   designated qualified medical institutions. To obtain an IDE, approval of
   the investigational plan for the applicable system is required from the
   institutional review board within each participating medical institution as
   well as from the FDA.

        The second stage of formal FDA market approval is the PMA application,
   which is submitted after sufficient data have been compiled under the IDE.
   The FDA will grant market approval if it finds that the safety and
   effectiveness of the product have been sufficiently demonstrated, and that
   the product complies with all applicable performance and manufacturing
   standards. No assurance can be given that any of the products under
   development by the Company currently or in the future, including the
   electric LVAS, will be approved by the FDA for commercial sale.

        The Company is also subject to the FDA's Good Manufacturing Practice
   (GMP) regulations. These regulations require that the Company manufacture
   its systems and maintain its records in a prescribed manner. The FDA
   
                                        6PAGE
<PAGE>
   inspects the Company's facilities for compliance with GMP. If the Company
   is found not to be in compliance, the FDA has broad powers to issue
   recalls, enjoin future violations, and assess civil and criminal penalties
   against the Company, its officers, and employees. In addition to GMP, the
   Company must adhere to quality standards applicable to European Community
   member countries and other countries where the Company sells its systems.

        To market and sell each of the Company's systems in European Community
   countries, the Company must obtain a CE Mark, which indicates that a
   product conforms to mandatory safety requirements. To sell its systems in
   other countries, the Company must comply with medical device regulations in
   each of such countries.

   Third Party Reimbursement

        The HeartMate IP LVAS is the only implantable, bridge-to-transplant
   ventricular-assist system approved for commercial sale by the FDA.

        In November 1995, the U.S. Health Care Finance Administration (HCFA)
   issued a decision that extends Medicare coverage to the Company's HeartMate
   IP LVAS. Part of the U.S. Department of Health and Human Services, HCFA is
   responsible for establishing coverage and reimbursement policies for
   Medicare and recommending guidelines for Medicaid. Many third party payers
   review HCFA recommendations to establish their own reimbursement policies.
   Several major nongovernment insurers, including Blue Cross/Blue Shield of
   Connecticut, Aetna Life & Casualty Company, and the health maintenance
   organization (HMO) U.S. Healthcare, have already agreed to offer converage
   for the IP LVAS. Additional insurers are reviewing the clinical results
   with the device, and additional coverage decisions will be forthcoming.

        Additionally, the ICD-9-CM coding committee has established a detailed
   resource code to be used when an implantable assist device such as the
   HeartMate IP LVAS is employed. This will facilitate collection of data on
   medical costs as well as resource information that may be used in
   establishing a Diagnosis Related Group (DRG) specific to ventricular-assist
   systems. HCFA and most states require that DRGs be used in determining the
   amount of reimbursement for particular procedures.

        Sales of the Company's systems will depend to a large degree upon the
   availability of reimbursement for the implantation of the devices. Even
   though reimbursement has been established by HCFA and by certain
   nongovernment insurers, the amount of available reimbursement may change,
   and reimbursement may be denied by an insurer under certain circumstances,
   including if it is determined that a procedure was not the most
   cost-effective treatment method, was experimental, or was used for an
   unapproved indication. No assurance can be given that additional
   third-party reimbursement for the HeartMate IP LVAS will be granted within
   a reasonable period of time, or at all, and the Company cannot predict what
   effect the future policies of government entities and insurers will have on
   the sale of the Company's devices. The unavailability of third party
   reimbursement for procedures involving the Company's systems would have a
   material adverse effect on the Company's business.


                                        7PAGE
<PAGE>
        (i) Manufacturing
  
        During 1994 and 1995, in anticipation of FDA approval of the IP LVAS,
   the Company more than doubled its manufacturing space and hired and trained
   new manufacturing personnel. As a result, the Company believes that its
   manufacturing capability is sufficient to meet anticipated demand for at
   least two years.

        (ii) New Products

        The Company's business consists primarily of research and development
   of new products to perform substantially all or part of the pumping
   function of the left ventricle of the natural heart for patients suffering
   from cardiovascular disease.

        (iii) Raw Materials

        The Company relies on a number of custom-designed components and
   materials supplied by other companies to manufacture its LVAS, most of
   which are available from a large number of suppliers. These suppliers, in
   turn, rely on one or two basic raw materials. In 1992, two major
   manufacturers, E. & M. DuPont de Nemours & Co. (DuPont) and Dow Corning
   (Dow), decided to phase out or eliminate their supply of raw materials for
   implantable medical devices. These withdrawals affected the availability of
   several components and materials the Company uses in its products.

        The Company has developed and received FDA approval for the use of one
   alternative material, and is in the process of qualifying certain other
   alternative materials or developing alternative sources for the materials
   no longer supplied by Dow and Dupont. While the Company believes that it
   has adequate supplies of materials to meet demand for the LVAS for the
   foreseeable future, no assurance can be given that the Company will not
   experience shortages of certain materials in the future that could delay
   shipments of the LVAS.

        The Company currently expects to spend approximately $2,000,000 on
   research, development, and the equipment necessary to test and obtain FDA
   approval for new alternative materials, approximately $1,390,000 of which
   has been spent to date. However, the cost to the Company to evaluate and
   test alternative materials and the time necessary to obtain FDA approval
   for these materials are inherently difficult to determine because both time
   and cost are dependent on at least two factors: the similarity of the
   alternative material to the original material, and the amount of
   third-party testing that may have already been completed on alternative
   materials.

        The Company does not expect that the introduction of alternative
   materials will adversely affect clinical trials of the electric LVAS. There
   can be no assurance, however, that the substitution of these materials will
   not cause delays in the Company's LVAS development program.

        (iv) Patents, Licenses and Trademarks

        The Company's policy is to protect its intellectual property rights
   relating to its work on cardiac-support systems including, if appropriate,
                                        8PAGE
<PAGE>
   applying for patents in the U.S. and foreign countries. Thermedics has
   granted the Company a royalty-free license to use the Dermaport(R) access
   device and Tecoflex(R) biomaterial in its LVAS. Although some of these
   patent rights may provide the Company with a competitive advantage, the
   Company primarily relies on its know-how and trade secrets developed over
   28 years of research, development, and fabrication of cardiac-assist
   devices. In April 1995, the Company received correspondence from a third
   party alleging that the textured surface of the LVAS housing infringed
   certain patent rights of such third party. The Company had previously
   received similar correspondence from this third party but had not received
   any communication for more than three years. In the April 1995
   communication, the third party offered the Company a license, which the
   Company has elected not to accept. Although the Company has not received
   any communication since April 1995 and believes that it has adequate
   defenses to the claims of the third party, due to the inherent uncertainty
   of litigation, no assurance can be made that the Company would be
   successful were any litigation to be commenced. The Company seeks to
   protect its proprietary information, but there can be no assurance that
   others will neither develop independently the same or similar information
   nor obtain access to information that the Company believes is proprietary.
   Moreover, there can be no assurance that others will not claim that the
   Company's activities infringe their intellectual property rights.

        (v) Seasonal Influences

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

        (vi) Working Capital Requirements

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

        (vii) Dependency on a Single Customer

        No customer accounted for 10% or more of the Company's total revenues
   in 1995. Revenues from AMETEC (a licensed distributor of the Company's LVAS
   products in Germany) accounted for 10% of the Company's total revenues in
   1994. Revenues from The Cleveland Clinic Foundation, AMETEC, and
   Columbia-Presbyterian Medical Center accounted for 14%, 11%, and 10%,
   respectively, of the Company's total revenues in 1993.

        (viii) Backlog

        The Company's backlog of firm orders was approximately $1,400,000 and
   $953,000 as of December 30, 1995 and December 31, 1994, respectively. The
   Company believes that substantially all of the backlog at December 30, 1995
   will be shipped or completed during the next 12 months.

        (ix) Government Contracts

        Not applicable.

        (x) Competition

        The Company is aware of one other company that has submitted a PMA
   application with the FDA for an implantable LVAS. The Company is unaware
   whether this PMA application has been accepted for filing by the FDA. Also,
   the Company is aware of one other company that has received approval by the
   FDA Advisory Panel on Circulatory System Devices and subsequent commercial
   approval for its cardiac-assist device. This is an external device,
   positioned on the outside of the patient's chest, and is intended for
   short-term use in the hospital environment. In addition, the Company is
   aware that a total artificial heart is currently undergoing clinical
   trials. The requirement of obtaining FDA approval for commercial sale of an
   LVAS in the U.S. is a significant barrier to entry into the U.S. market for
   these devices. There can be no assurance, however, that FDA regulations
   will not change in the future, reducing the time and testing required for
   others to obtain FDA approval for commercial sale. In addition, other
   research groups and companies, some of which have significantly greater
   resources than those of the Company, are developing cardiac systems using
   alternative technologies or concepts, one or more of which might prove
   functionally equivalent to or more suitable than the Company's systems.
   Among products that have been approved for commercial sale, the Company
   competes primarily on the basis of performance, service capability, and
   price. Competition in the market for medical devices is also significantly
   affected by the reimbursement policies of government and private insurers.
   Any product for which reimbursement is not available from such third-party
   payors will be at a significant competitive disadvantage. In November 1995,
   the HCFA issued a decision that extends Medicare coverage to the IP LVAS.
   Several major health insurers including Aetna and U.S. Health Care have
   agreed to offer coverage for the IP LVAS, while many others are reimbursing
   on a case-by-case basis.

        (xi) Research and Development

        During 1995, 1994, and 1993, the Company expended approximately
   $3,324,000, $3,437,000, and $2,976,000, respectively, on internally
   sponsored research and development programs. Approximately 28 professional
   employees were engaged full-time in research and development activities at
   December 30, 1995.

        (xii) Environmental Protection Regulations

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

        (xiii) Number of Employees

        As of December 30, 1995, the Company had a total of 122 employees.
   None of the Company's employees is represented by a labor union, and the
   Company considers its relations with its employees to be good.

   (d)  Financial Information about Exports by Domestic Operations.

        Financial information about exports by domestic operations is
   summarized in Note 8 to Financial Statements in the Registrant's 1995
   Annual Report to Shareholders and is incorporated herein by reference.

   Paul F. Kelleher                 53   Chief Accounting Officer (1988)

        Each executive officer serves until his or her successor is chosen or
   appointed by the Board of Directors and qualified or until earlier
   resignation, death, or removal. All executive officers, except Mr.
   Krauskopf, have held comparable positions for at least five years with the
   Company, Thermedics, or Thermo Electron. Mr. Poirier and Dr. Dasse devote
   substantially all of their time to the affairs of the Company, but devote a
   portion of their time to the affairs of Thermedics. Messrs. Hatsopoulos and
   Kelleher are full-time employees of Thermo Electron, but devote such time
   to the affairs of the Company as the Company's needs reasonably require.
   Mr. Krauskopf was previously Director of Regulatory Affairs from 1993 to
   1995, and prior to that, was Senior Regulatory Affairs Coordinator at USCI
   division of C.R. Bard, Inc. from 1992 to 1993, and worked in clinical
   affairs at Carbomedics, Inc. from 1989 to 1992. 


   Item 2. Properties

        The Company currently subleases approximately 31,536 square feet of
   space in Thermedics' corporate headquarters in Woburn, Massachusetts. This
   sublease expires in February 1999. Under the terms of the sublease, the
   Company pays approximately the same rent paid per square foot by Thermedics
   under its prime lease. The Company believes that these facilities are in
   good condition and are suitable for its present operations.

   To the Shareholders and Board of Directors of Thermo Cardiosystems Inc.:

        We have audited, in accordance with generally accepted auditing
   standards, the financial statements included in Thermo Cardiosystems Inc.'s
   Annual Report to Shareholders incorporated by reference in this Form 10-K,
   and have issued our report thereon dated February 7, 1996. Our audits were
   made for the purpose of forming an opinion on those statements taken as a
   whole. The schedule listed in Item 14 on page 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
   financial statements. The schedule has been subjected to the auditing
   procedures applied in the audits of the basic 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 financial
   statements taken as a whole.

                           THERMO ELECTRON CORPORATION

                   THERMOQUEST 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  ThermoQuest Corporation  ("Subsidiary"),  a
        subsidiary of  Thermo Electron  Corporation (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 and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  375,000  shares, subject 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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
        option price of  the shares to  be purchased; provided,  however,
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  as  a  whole   or
        substantially as a  whole, the Optionee  shall, upon exercise  of
PAGE
<PAGE>
        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 Subsidiary,  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.  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
PAGE
<PAGE>
        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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2006 and no  options shall be  granted
        hereunder thereafter.


                                                           EXHIBIT 10.42
                           THERMO ELECTRON CORPORATION

                   THERMO OPTEK 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  Thermo Optek  Corporation ("Subsidiary"),  a
        subsidiary of  Thermo Electron  Corporation (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 and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  250,000  shares, subject 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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  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
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  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
PAGE
<PAGE>
        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 Subsidiary,  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.  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
PAGE
<PAGE>
        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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2006 and no  options shall be  granted
        hereunder thereafter.


                                                         EXHIBIT 10.43
                           THERMO ELECTRON CORPORATION

                  THERMO SENTRON 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  Thermo  Sentron  Inc.  ("Subsidiary"),   a
        subsidiary of  Thermo Electron  Corporation (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 and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  150,000  shares, subject 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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  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
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  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
PAGE
<PAGE>
        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 Subsidiary,  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.  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
PAGE
<PAGE>
        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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2006 and no  options shall be  granted
        hereunder thereafter.


                                                        EXHIBIT 10.44
                           THERMO ELECTRON CORPORATION

                   TREX MEDICAL 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  Trex Medical  Corporation ("Subsidiary"),  a
        subsidiary of  Thermo Electron  Corporation (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 and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  250,000  shares, subject 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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  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
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  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
PAGE
<PAGE>
        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 Subsidiary,  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.  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
PAGE
<PAGE>
        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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2006 and no  options shall be  granted
        hereunder thereafter.


                                                          EXHIBIT 10.51
                                 THERMEDICS INC.

                  THERMO SENTRON 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  Thermo  Sentron  Inc.  ("Subsidiary"),   a
        subsidiary  of  Thermedics  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  and its  subsidiaries,
        and to  provide  additional incentive  for  them to  promote  the
        success of the business of the Company and Subsidiary.  The  Plan
        is intended to be a nonstatutory stock option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  100,000  shares, subject 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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  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,
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  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
PAGE
<PAGE>
        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 Subsidiary,  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.  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
PAGE
<PAGE>
        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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2005 and no  options shall be  granted
        hereunder thereafter.

                              EQUITY INCENTIVE PLAN

        1.   Purpose
             -------
             The purpose of this Equity Incentive Plan (the "Plan") is to
        secure  for  Thermo   Sentron  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
             --------------
PAGE
<PAGE>
                                        2
             The Plan shall be effective as of the date first approved by
        the Board of Directors,  subject to the approval  of the Plan  by
        the Corporation's Stockholders. Grants  of Awards under the  Plan
        made prior to such approval shall be effective when made  (unless
        otherwise specified by the Board at the time of grant), but shall
        be conditioned on and subject to such approval of the Plan.

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

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

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

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

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

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

             The Board may  offer Awards under  the Plan in  any form  of
        equity-based     interest,     equity-based     incentive      or
        performance-based stock incentive in Common Stock of the  Company
        or any combination thereof.   The type, terms and conditions  and
        restrictions of an Award shall be determined by the Board at  the
        time such Award is made to a Participant.

             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.  

             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
PAGE
<PAGE>
                                        4
        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 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 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, discharging all the

                                        7
        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.

             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.

                  -----------------------

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

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

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

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

             10.4 Tax Withholding
                  ---------------

                                       10
             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.

                                       11
             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 10.64
                         THERMO INSTRUMENT SYSTEMS INC.

                THERMO BIOANALYSIS NONQUALIFIED STOCK OPTION PLAN

        1.   Purpose
             -------
             This Nonqualified Stock Option Plan (the "Plan") is intended
        to encourage ownership  of Common  Stock, $0.001  par value  (the
        "Common    Stock"),    of    Thermo    BioAnalysis    Corporation
        ("Subsidiary"), 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  and  its  subsidiaries, and  to  provide  additional
        incentive for them to promote the success of the business of  the
        Company  and  Subsidiary.    The   Plan  is  intended  to  be   a
        nonstatutory stock option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  100,000  shares, subject  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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  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
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  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
PAGE
<PAGE>
        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 Subsidiary,  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.  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
PAGE
<PAGE>
        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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2005 and no  options shall be  granted
        hereunder thereafter.


                                                           EXHIBIT 10.65
                         THERMO INSTRUMENT SYSTEMS INC.

                   THERMOQUEST 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  ThermoQuest Corporation  ("Subsidiary"),  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 and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  750,000  shares,  subject  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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  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
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  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
PAGE
<PAGE>
        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 Subsidiary,  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.  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
PAGE
<PAGE>
        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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2005 and no  options shall be  granted
        hereunder thereafter.

                         THERMO BIOANALYSIS CORPORATION

                              EQUITY INCENTIVE PLAN

        1.   Purpose
             -------
             The purpose of this Equity Incentive Plan (the "Plan") is to
        secure for Thermo BioAnalysis 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

                                        2
             The Plan shall be effective as of the date first approved by
        the Board of Directors,  subject to the approval  of the Plan  by
        the Corporation's Stockholders. Grants  of Awards under the  Plan
        made prior to such approval shall be effective when made  (unless
        otherwise specified by the Board at the time of grant), but shall
        be conditioned on and subject to such approval of the Plan.

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

             Subject to adjustment as provided in Section 10.6, the total
        number of shares of the common  stock, $.01 par value per  share,
        of the Company (the "Common  Stock"), reserved and available  for
        distribution under the Plan shall be 600,000 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
PAGE
<PAGE>
                                        3
        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.  

             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
PAGE
<PAGE>
                                        4
        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 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
PAGE
<PAGE>
                                        5
        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 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

                                        7
        necessary to make him or her whole after tax, discharging all the
        participant's income tax  liabilities arising  from all  payments

        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.

             ------------------

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

             Awards will be evidenced  by written instruments, which  may
        differ among Participants, prescribed by  the Board from time  to
PAGE
<PAGE>
                                        9
        time.  Such instruments  may be in the  form of agreements to  be
        executed by both the Participant and the Company or certificates,
        letters or similar instruments which need not be executed by  the
        participant but acceptance  of which will  evidence agreement  to
        the terms  thereof.    Such  instruments  shall  conform  to  the
        requirements of the  Plan and may  contain such other  provisions
        (including   provisions   relating    to   events   of    merger,
        consolidation, dissolution  and liquidations,  change of  control
        and restrictions  affecting either  the agreement  or the  Common
        Stock issued thereunder), as the Board deems advisable.

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

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

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

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

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

             10.4 Tax Withholding
                  ---------------

             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
PAGE
<PAGE>
                                       10
        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.

             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
PAGE
<PAGE>
                                       11
        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
PAGE
<PAGE>
                                       12        
        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 10.68
                            THERMO OPTEK CORPORATION

                              EQUITY INCENTIVE PLAN

        1.   Purpose
             -------
             The purpose of this Equity Incentive Plan (the "Plan") is to
        secure for  Thermo  Optek  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
             --------------
PAGE
<PAGE>
                                       2
             The Plan shall be effective as of the date first approved by
        the Board of Directors,  subject to the approval  of the Plan  by
        the Corporation's Stockholders. Grants  of Awards under the  Plan
        made prior to such approval shall be effective when made  (unless
        otherwise specified by the Board at the time of grant), but shall
        be conditioned on and subject to such approval of the Plan.

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

             Subject to adjustment as provided in Section 10.6, the total
        number of shares of the common  stock, $.01 par value per  share,
        of the Company (the "Common  Stock"), reserved and available  for
        distribution under  the Plan  shall be  1,800,000 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
PAGE
<PAGE>
                                        3
        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.  

             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
PAGE
<PAGE>
                                        4
        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 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

        of mergers, consolidations, dissolutions and liquidations) as the
        Board shall deem advisable.

             6.2.2     Restrictions.  Until the restrictions specified in

        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.

        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

        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

        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.

        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.

        is granted, impose the condition  (in addition to any  conditions

        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, discharging all the
        participant's income tax  liabilities arising  from all  payments

        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.

        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
                  -------------------------------
PAGE
<PAGE>
                                        9
             The Company will not be  obligated to deliver any shares  of
        Common Stock pursuant to  the Plan or  to remove any  restriction
        from shares previously  delivered under  the Plan  (a) until  all
        conditions of  the  Award have  been  satisfied or  removed,  (b)
        until, in the  opinion of the  Company's counsel, all  applicable
        federal and state laws and  regulations have been complied  with,
        (c) if the outstanding Common Stock is at the time listed on  any
        stock exchange, until the shares  have been listed or  authorized
        to be listed on such  exchange upon official notice of  issuance,
        and (d)  until all  other legal  matters in  connection with  the
        issuance and delivery of  such shares have  been approved by  the
        Company's counsel.   If the  sale of  Common Stock  has not  been
        registered under  the Securities  Act of  1933, as  amended,  the
        Company may require,  as a  condition to exercise  of the  Award,
        such representations or agreements as counsel for the Company may
        consider appropriate  to  avoid violation  of  such act  and  may
        require that the certificates  evidencing such Common Stock  bear
        an appropriate legend restricting transfer.

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

             10.4 Tax Withholding
                  ---------------

             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
PAGE
<PAGE>
                                       10
        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 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
PAGE
<PAGE>
                                       11
        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
                             THERMOQUEST CORPORATION

                              EQUITY INCENTIVE PLAN

        1.   Purpose
             -------
             The purpose of this Equity Incentive Plan (the "Plan") is to
        secure  for  ThermoQuest  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
             --------------
PAGE
<PAGE>
                                        2
             The Plan shall be effective as of the date first approved by
        the Board of Directors,  subject to the approval  of the Plan  by
        the Corporation's Stockholders. Grants  of Awards under the  Plan
        made prior to such approval shall be effective when made  (unless
        otherwise specified by the Board at the time of grant), but shall
        be conditioned on and subject to such approval of the Plan.

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

             Subject to adjustment as provided in Section 10.6, the total
        number of shares of the common  stock, $.01 par value per  share,
        of the Company (the "Common  Stock"), reserved and available  for
        distribution under  the Plan  shall be  1,800,000 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
PAGE
<PAGE>
                                        3
        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.  

             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
PAGE
<PAGE>
                                        4
        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 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
PAGE
<PAGE>
                                        5
        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 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
PAGE

                                        7
        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.

        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
                  -------------------------------
PAGE
<PAGE>
                                        9
             The Company will not be  obligated to deliver any shares  of
        Common Stock pursuant to  the Plan or  to remove any  restriction
        from shares previously  delivered under  the Plan  (a) until  all
        conditions of  the  Award have  been  satisfied or  removed,  (b)
        until, in the  opinion of the  Company's counsel, all  applicable
        federal and state laws and  regulations have been complied  with,
        (c) if the outstanding Common Stock is at the time listed on  any
        stock exchange, until the shares  have been listed or  authorized
        to be listed on such  exchange upon official notice of  issuance,
        and (d)  until all  other legal  matters in  connection with  the
        issuance and delivery of  such shares have  been approved by  the
        Company's counsel.   If the  sale of  Common Stock  has not  been
        registered under  the Securities  Act of  1933, as  amended,  the
        Company may require,  as a  condition to exercise  of the  Award,
        such representations or agreements as counsel for the Company may
        consider appropriate  to  avoid violation  of  such act  and  may
        require that the certificates  evidencing such Common Stock  bear
        an appropriate legend restricting transfer.

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

             10.4 Tax Withholding
                  ---------------

             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
PAGE
<PAGE>
                                       10
        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 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
PAGE
<PAGE>
                                       11
        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 10.73
                             THERMOTREX CORPORATION

                   TREX MEDICAL 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 Trex  Medical Corporaton  ("Subsidiary"),  a
        subsidiary of ThermoTrex Corporation (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  and its  subsidiaries,
        and to  provide  additional incentive  for  them to  promote  the
        success of the business of the Company and Subsidiary.  The  Plan
        is intended to be a nonstatutory stock option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  400,000  shares,  subject  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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  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
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  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
PAGE
<PAGE>
        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 Subsidiary,  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.  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
PAGE
<PAGE>
        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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2006 and no  options shall be  granted
        hereunder thereafter.



                                                           EXHIBIT 10.73
                             THERMOTREX CORPORATION

                   TREX MEDICAL 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 Trex  Medical Corporaton  ("Subsidiary"),  a
        subsidiary of ThermoTrex Corporation (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  and its  subsidiaries,
        and to  provide  additional incentive  for  them to  promote  the
        success of the business of the Company and Subsidiary.  The  Plan
        is intended to be a nonstatutory stock option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  400,000  shares,  subject  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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  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
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  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
PAGE
<PAGE>
        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 Subsidiary,  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.  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
PAGE
<PAGE>
        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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2006 and no  options shall be  granted
        hereunder thereafter.



                                                            EXHIBIT 10.84
                            THERMO POWER CORPORATION

                    THERMOLYTE 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  ThermoLyte  Corporation  ("Subsidiary"),  a
        subsidiary  of  Thermo  Power  Corporation  (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 and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan
             --------------------------
             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        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  100,000  shares,  subject  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
        Subsidiary 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
PAGE
<PAGE>
        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
        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 one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company 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 Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
PAGE
<PAGE>
        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, Subsidiary  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 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  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  as  a  whole   or
PAGE
<PAGE>
        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 Subsidiary,  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.  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
             --------------
PAGE
<PAGE>
             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 shall have the right to deduct from payments  of
        any kind otherwise due to an 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  (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  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
PAGE
<PAGE>
        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 on December 31,  2006 and no  options shall be  granted
        hereunder thereafter.

   1.   Nature of Operations and Summary of Significant Accounting Policies

   Nature of Operations
   Thermo Cardiosystems Inc. (the Company) is a leader in the research,
   development, and manufacture of implantable left ventricular-assist systems
   (LVAS). Its HeartMate(R) devices are designed to perform substantially all
   or part of the pumping function of the left ventricle of the natural heart
   for patients suffering from cardiovascular disease. 

   Relationship with Thermedics Inc. and Thermo Electron Corporation
   The Company was incorporated in 1988 as a wholly owned subsidiary of
   Thermedics Inc. (Thermedics). Prior to that time, the business was
   conducted as a division of Thermedics.
        As of December 30, 1995, Thermedics owned 12,525,110 shares of the
   Company's common stock, representing 52% of such stock outstanding.
   Thermedics is a 51%-owned subsidiary of Thermo Electron Corporation (Thermo
   Electron). As of December 30, 1995, Thermo Electron owned 659,967 shares of
   the Company's common stock, representing 3% of such stock outstanding.

   Fiscal Year
   The Company has adopted a fiscal year ending the Saturday nearest 
   December 31. References to 1995, 1994, and 1993 are for the fiscal years
   ended December 30, 1995, December 31, 1994, and January 1, 1994,
   respectively.

   Cash and Cash Equivalents
   As of December 30, 1995, $4,379,000 of the Company's cash equivalents were
   invested in a repurchase agreement with Thermo Electron. Under this
   agreement, the Company in effect lends excess cash to Thermo Electron,
   which Thermo Electron collateralizes with investments principally
   consisting of U.S. government agency securities, corporate notes,
   commercial paper, money market funds, and other marketable securities, in
   the amount of at least 103% of such obligation. The Company's funds subject
   to the repurchase agreement are readily convertible into cash by the
   Company 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. Cash
   equivalents are carried at cost, which approximates market value.

   Available-for-sale Investments
   Pursuant to Statement of Financial Accounting Standards (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.

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

                                                          ======    ======
   Machinery, Equipment and Leasehold Improvements
   The costs of additions and improvements are capitalized, while maintenance
   and repairs are charged to expense as incurred. The Company provides for
   depreciation and amortization using the straight-line method over the
   estimated useful lives of the property, as follows: machinery and equipment
   -- five to eight years, and leasehold improvements -- the shorter of the
   term of the lease or the life of the asset.

   Common Stock Subject to Redemption
   Common stock subject to redemption in the accompanying statement of
   shareholders' investment represents amounts associated with redemption
   rights outstanding that were issued in connection with the Company's 1989
   initial public offering. These redemption rights expired at the end of
   1993, and as a result, the Company transferred $5,468,000 of common stock
   subject to redemption to common stock and capital in excess of par value.

   Revenue Recognition
   The Company recognizes revenues upon shipment of its products. The Company
   provides a reserve for its estimate of warranty costs at the time of
   shipment. The Company had deferred revenue of $258,000 in the accompanying
   1994 balance sheet relating to orders for implementation programs not fully
   completed in 1994.

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

   Earnings per Share
   Earnings per share have been computed based upon the weighted average
   number of shares outstanding during the year. Weighted average shares in
   1995 and 1994 include the effect of common stock equivalents, which
   represent the assumed conversion of the Company's noninterest-bearing
   subordinated convertible debentures and the assumed exercise of stock
   options that were computed using the treasury stock method. In 1993, the
   effect of the assumed conversion of the Company's subordinated notes was
   antidilutive and the effect of the assumed exercise of stock options was
   immaterial.

   Notes to Financial Statements


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

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


   2.   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 (loss) on
   available-for-sale investments." Effect of change in accounting principle
   in the accompanying 1994 statement of shareholders' investment represents
   the unrealized gain, net of related tax effects, pertaining to available-
   for-sale investments held by the Company on January 2, 1994.
        The aggregate market value, cost basis, and gross unrealized gains and
   losses of short- and long-term available-for-sale investments by major
   security type, as of December 30, 1995 and December 31, 1994, are as
   follows:

   2.   Available-for-sale Investments (continued)

        Short- and long-term available-for-sale investments in the
   accompanying 1995 balance sheet include $39,912,000 with contractual
   maturities of one year or less, $38,895,000 with contractual maturities of
   more than one year through five years, and $7,269,000 with contractual
   maturities of more than 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 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 resulted from
   gross realized gains of $439,000 and gross realized losses of $18,000 in
   1995, and gross realized gains of $97,000 in 1994, relating to the sale of
   available-for-sale investments.


   3.   Stock-based Compensation Plans

   The Company has stock-based compensation plans for its key employees,
   directors, and others. Two of these plans, adopted in 1988, permit the
   grant of nonqualified and incentive stock options. A third plan, adopted in
   1994, permits the grant of a variety of stock and stock-based awards as
   determined by the human resources committee of the Company's Board of
   Directors (the Board Committee), including restricted stock, stock options,
   stock bonus shares, or performance-based shares. To date, only nonqualified
   stock options have been awarded under this plan. The option recipients and
   the terms of options granted under 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 five to ten years after
   the first anniversary of the grant date, depending on the term of the
   option, which may range from seven to twelve years. Nonqualified options
   may be granted at any price determined by the Board Committee, although
   incentive stock options must be granted at not less than the fair market
   value of the Company's stock on the date of grant. To date, 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 of stock
   options to outside 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.

   3.   Stock-based Compensation Plans (continued)

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

   4.   Employee Benefit Plans

   Employee Stock Purchase Plan
   Substantially all of the Company's full-time employees are eligible to
   participate in the Company's employee stock purchase plan. Prior to the
   November 1995 plan year, shares of the Company's and Thermo Electron's
   common stock could 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 were subject to a one-year resale restriction. Effective November
   1, 1995, the applicable shares of common stock may be purchased at 95% of
   the fair market value at the beginning of the plan year, and the shares
   purchased are subject to a six-month resale restriction. Shares are
   purchased through payroll deductions of up to 10% of each participating
   employee's gross wages. During 1995, 1994, and 1993, the Company issued
   5,254 shares, 4,930 shares, and 8,226 shares, respectively, of its common
   stock under this plan.

   401(k) Savings Plan
   Substantially all of the Company's full-time employees are eligible to
   participate in Thermo Electron's 401(k) savings plan. Contributions to the
   plan are made by both the employee and the Company. Company contributions
   are based upon the level of employee contributions. For this plan, the
   Company contributed and charged to expense $135,000, $91,000, and $61,000
   in 1995, 1994, and 1993, respectively.

        The provision for income taxes that is currently payable does not
   reflect $3,335,000 of tax benefits allocated to capital in excess of par
   value in 1995.
        The provision for income taxes in the accompanying statement of income
   differs from the provision calculated by applying the statutory federal
   income tax rate of 34% to income before provision for income taxes due to
   the following:

        The valuation allowance primarily related to the uncertainty of the
   realizability of future federal and state tax benefits. The valuation
   allowance was eliminated as a result of reduced uncertainty surrounding the
   realizability of such future tax benefits. A portion of the reduction in
   the valuation allowance was related to stock options and was recorded as an
   increase to capital in excess of par value.


   6.   Subordinated Convertible Obligations

   In January 1994, the Company issued and sold at par $33,000,000 principal
   amount of noninterest-bearing subordinated convertible debentures due 1997.
   The debentures are convertible into shares of the Company's common stock at
   a conversion price of $21.74 per share. During 1995, $21,358,000 of the
   noninterest-bearing subordinated convertible debentures were converted into
   982,415 shares of the Company's common stock.
        In February 1992, the Company issued and sold $600,000 principal
   amount of 5 1/2% subordinated convertible notes due 2002. The notes were
   convertible into shares of the Company's common stock at a conversion price
   of $9.88 per share. During 1995 and 1994, $450,000 and $150,000,
   respectively, of the 5 1/2% subordinated convertible notes were converted
   into 45,569 shares and 15,189 shares, respectively, of the Company's common
   stock.
        The Company's convertible obligations are guaranteed on a subordinated
   basis by Thermo Electron. Thermedics has agreed to reimburse Thermo
   Electron in the event Thermo Electron is required to make a payment under
   the guarantee.
        See Note 11 for the fair value of the Company's long-term obligations.

   7.   Related Party Transactions

   Corporate Services Agreement
   The Company and Thermo Electron have a corporate services agreement under
   which Thermo Electron's corporate staff provides certain administrative
   services, including certain legal advice and services, risk management,
   certain employee benefit administration, tax advice and preparation of tax
   returns, centralized cash management, and certain financial and other
   services, for which the Company paid Thermo Electron annually an amount
   equal to 1.20% of the Company's revenues in fiscal 1995 and 1.25% of the
   Company's revenues in fiscal 1994 and 1993. Beginning in fiscal 1996, the
   Company will pay an annual fee equal to 1.0% of the Company's revenues. The
   annual fee is reviewed and adjusted annually by mutual agreement of the
   parties. The corporate services agreement is renewed annually but can be
   terminated upon 30 days' prior notice by the Company or upon the Company's
   withdrawal from the Thermo Electron Corporate Charter (the Thermo Electron
   Corporate Charter defines the relationship among Thermo Electron and its
   majority-owned subsidiaries). In addition, the Company uses data processing
   services of a majority-owned subsidiary of Thermo Electron, and accounting,
   personnel, and administrative services of Thermedics. For these services,
   as well as the administrative services provided by Thermo Electron, the
   Company was charged $478,000, $368,000, and $313,000 in 1995, 1994, and
   1993, respectively. Management believes that the service fees charged by
   Thermo Electron, its majority-owned subsidiary, and Thermedics are
   reasonable and that such fees are representative of the expenses the
   Company would have incurred on a stand-alone basis. For additional items
   such as employee benefit plans, insurance coverage, and other identifiable
   costs, Thermo Electron charges the Company based upon costs attributable to
   the Company.

   Operating Leases
   The Company subleases office and research facilities from Thermedics and is
   charged for actual square footage occupied at approximately the same rent
   paid per square foot by Thermedics under its prime lease. This sublease
   expires in February 1999. The accompanying statement of income includes
   expenses from the sublease of $134,000, $140,000, and $156,000 in 1995,
   1994, and 1993, respectively. Currently, the cost of the area occupied by
   the Company is $134,000 per year.

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


   8.   Significant Customers, Export Sales and Concentrations of Risk

   No customer accounted for 10% or more of the Company's total revenues in
   1995. Revenues from AMETEC (a licensed distributor of the Company's LVAS in
   Germany) accounted for 10% of the Company's total revenues in 1994.
   Revenues from The Cleveland Clinic Foundation, AMETEC, and Columbia-
   Presbyterian Medical Center accounted for 14%, 11%, and 10%, respectively,
   of the Company's total revenues in 1993.

   Notes to Financial Statements


   8.   Significant Customers, Export Sales and Concentrations of Risk 
        (continued)

        In 1995, export revenues were $2,353,000. In 1994, export revenues to
   Germany, other European countries, and other countries were $1,032,000,
   $1,278,000, and $817,000, respectively. In 1993, export revenues to
   Germany, other European countries, and other countries were $381,000,
   $599,000, and $451,000, respectively. Export revenues are denominated in
   U.S. dollars.
        Certain raw materials used in the manufacture of the Company's LVAS
   are available from only one supplier. While the Company believes that it
   has adequate supplies of materials to meet demand for the LVAS for the
   foreseeable future, no assurance can be given that the Company will not
   experience shortages of certain materials in the future that could delay
   shipments of the LVAS.


   9.   Stock Purchase Warrant and Common Stock

   In May 1993, in connection with an agreement to develop a material to be
   used in the Company's LVAS, the Company granted to a third party the right
   to purchase from the Company 40,000 shares of the Company's common stock at
   a price of $8.74 per share, which was the fair market value of the
   Company's common stock on the date of grant. This warrant is exercisable
   immediately and expires ten years after the date of grant.
        At December 30, 1995, the Company had reserved 1,925,617 unissued
   shares of its common stock for possible issuance under stock-based
   compensation plans, possible conversion of its outstanding subordinated
   convertible debentures, and possible issuance under the stock purchase
   warrant.


   10.  Contingency 

   The Company has received correspondence alleging that the textured surface
   of its LVAS housing infringes the intellectual property rights of another
   party. In general, an owner of intellectual property can prevent others
   from using such property without a license and is entitled to damages for
   unauthorized past usage. The Company has investigated the bases of the
   allegation and, based on the opinion of its counsel, believes that if the
   Company were sued on these bases, it would have meritorious defenses.


   11.  Fair Value of Financial Instruments 

   The Company's financial instruments consist mainly of cash and cash
   equivalents, available-for-sale investments, accounts receivable, accounts
   payable, due to parent company, and subordinated convertible obligations.
   The carrying amounts of these financial instruments, with the exception of
   available-for-sale investments and subordinated convertible obligations,
   approximates fair value due to their short-term nature.

   11.  Fair Value of Financial Instruments (continued)

        Available-for-sale investments are carried at fair value in the
   accompanying balance sheet. The fair values were determined based on quoted
   market prices. See Note 2 for fair value information pertaining to these
   financial instruments.
        The fair value of the Company's subordinated convertible obligations
   was determined based on quoted market prices. The carrying amount and fair
   value of the Company's subordinated convertible obligations are as follows:

                                    1995                       1994

   (1) The fair value of subordinated convertible obligations at year-end
       1995 exceeds the carrying amount primarily due to the market price of
       the Company's common stock exceeding the conversion price of the
       subordinated convertible obligations.

   Report of Independent Public Accountants


   To the Shareholders and Board of Directors of Thermo Cardiosystems Inc.:

   We have audited the accompanying balance sheets of Thermo Cardiosystems
   Inc. (a Massachusetts corporation and 52%-owned subsidiary of Thermedics
   Inc.) as of December 30, 1995 and December 31, 1994, and the related
   statements of income, shareholders' investment, and cash flows for each of
   the three years in the period ended December 30, 1995. These financial
   statements are the responsibility of the Company's management. Our
   responsibility is to express an opinion on these financial statements based
   on our audits.
        We conducted our audits in accordance with generally accepted auditing
   standards. Those standards require that we plan and perform the audit to
   obtain reasonable assurance about whether the financial statements are free
   of material misstatement. An audit includes examining, on a test basis,
   evidence supporting the amounts and disclosures in the financial
   statements. An audit also includes assessing the accounting principles used
   and significant estimates made by management, as well as evaluating the
   overall financial statement presentation. We believe that our audits
   provide a reasonable basis for our opinion.
        In our opinion, the financial statements referred to above present
   fairly, in all material respects, the financial position of Thermo
   Cardiosystems Inc. as of December 30, 1995 and December 31, 1994, and the
   results of its operations and its cash flows for each of the three years in
   the period ended December 30, 1995, in conformity with generally accepted
   accounting principles.
        As discussed in Note 2 to the financial statements, effective January
   2, 1994, the Company changed its method of accounting for investments in
   debt and marketable equity securities.

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

   Overview

   The Company is a leader in the research, development, and manufacture of
   both an air-driven and an electric implantable left ventricular-assist
   system (LVAS). The Company is also the only company with U.S. Food and Drug
   Administration (FDA) approval to commercially market an implantable LVAS.
   Each system is designed to perform substantially all or part of the pumping
   function of the left ventricle of the natural heart for patients suffering
   from cardiovascular disease. Unlike total artificial heart systems, which
   require removal of the natural heart, an LVAS allows the natural heart to
   be left in place, preserving the heart's biological control mechanisms.
        In October 1994, the Company announced that the FDA granted approval
   for the commercial sale in the U.S. of the air-driven LVAS for use as a
   bridge-to-transplant. With this approval, the air-driven system became
   available to cardiac centers throughout the United States. In April 1994,
   the Company received the European Conformity Mark (CE Mark) for commercial
   sale of the air-driven LVAS in all European Community countries. Until the
   Company's electric LVAS receives FDA commercial approval, sales of the
   electric LVAS will fluctuate depending upon the number of implants
   performed in ongoing studies at approved clinical sites and the number of
   implementation programs sold. The electric version of the LVAS is currently
   being used in the U.S. in clinical trials for patients awaiting heart
   transplants and, in late 1995, the FDA approved the protocol for conducting
   clinical trials of the electric LVAS as an alternative to heart transplant.
   In August 1995, the Company received the CE Mark allowing commercial sale
   of the electric LVAS in European Community countries. It is being used in
   Europe as both a bridge-to-transplant and as an alternative to heart
   transplant.
        In general, a profit cannot be earned from the sale of an LVAS until
   approval of the device has been received from the FDA for commercial sale.
   Until such approval is obtained, only the direct and indirect costs of the
   LVAS can be recovered, which are included in the Company's revenues. With
   the FDA's approval of the air-driven LVAS, the Company began earning a
   profit on the sale of such systems in the fourth quarter of 1994. In
   October 1994, the Company announced a price increase in the U.S. for its
   air-driven LVAS that was phased in during a six-month period and that more
   than doubled the average price of the air-driven LVAS.
        The Company derives its revenues from two types of sales:
   implementation programs and subsequent implants. Implementation programs
   consist of initial sales to new clinical centers or foreign distributors,
   as well as sales of a new system, such as the electric LVAS, to an existing
   customer. Revenues recorded from subsequent implants consist of sales to an
   existing customer other than the initial sale of the implementation
   program. In general, the Company receives greater revenues from the sale of
   an implementation program than from a subsequent implant.

   Results of Operations

   1995 Compared With 1994

   Revenues almost doubled in 1995 to $20,593,000 from $10,409,000 in 1994.
   Revenues in 1995 increased approximately 47% as a result of the price
   increase that was phased in during the fourth quarter of 1994 and the first
   two quarters of 1995. Revenues also increased due to a 43% increase in the
   number of air-driven and electric LVAS units shipped during 1995 compared
   with 1994. The number of implementation programs sold in 1995 were
   comparable to those sold in 1994.
        The gross profit margin increased to 57% in 1995 from 51% in 1994,
   primarily due to the price increase and, to a lesser extent, the increase
   in sales volume and improvements in manufacturing efficiencies. The Company
   will continue to be unable to earn a profit on sales of the electric LVAS
   until FDA approval of that system is obtained.
        The Company recorded operating income of $4,313,000 in 1995, compared
   with an operating loss of $944,000 in 1994. This improvement resulted
   primarily from an increased gross profit margin on higher revenues,
   partially offset by increased expenses to market and distribute the
   Company's LVAS.
        Interest income increased to $5,117,000 in 1995 from $4,147,000 in
   1994, principally due to higher prevailing interest rates in 1995 compared
   with 1994. Interest expense decreased to $274,000 in 1995 from $375,000 in
   1994, primarily as a result of lower amortization of deferred issuance
   costs associated with the Company's noninterest-bearing subordinated
   convertible debentures due to the conversion of $21,358,000 principal
   amount of these debentures in 1995.
        The effective tax rate decreased to 28% in 1995 from 35% in 1994,
   primarily due to the reversal of the tax valuation allowance that was no
   longer required (Note 5).

   1994 Compared With 1993

   Revenues in 1994 were $10,409,000, compared with $3,524,000 in 1993.
   Revenues increased in 1994 principally due to an increase in the number of
   implementation programs sold. Thirty-one implementation programs were sold
   in 1994, compared with ten implementation programs sold in 1993. Eight
   implementation programs, or 26% of the total programs sold in 1994, were a
   result of FDA commercial approval of the air-driven LVAS. The increase in
   revenues also reflects an increase in the number of subsequent implants,
   primarily of the air-driven LVAS, performed at existing sites in 1994. Of
   the total increase in revenues in the fourth quarter of 1994, approximately
   $250,000 was a result of the price increase that became effective during
   that period.
        The gross profit margin increased to 51% in 1994 from 43% in 1993,
   primarily due to the increase in sales volume, improvements in
   manufacturing efficiencies, and the first phase of the price increase for
   the air-driven system, which became effective in the fourth quarter of
   1994.

   Management's Discussion and Analysis of Financial Condition and Results of
   Operations (continued)

   1994 Compared With 1993 (continued)

        The Company recorded an operating loss of $944,000 in 1994, compared
   with a loss of $3,174,000 in 1993. The lower operating loss resulted
   primarily from an increased gross profit margin on higher revenues,
   partially offset by increased expenses to develop and market the Company's
   LVAS. The Company recorded operating income of $384,000 in the fourth
   quarter of 1994.
        Interest income increased to $4,147,000 in 1994 from $3,508,000 in
   1993, primarily as a result of higher average invested amounts derived from
   the Company's issuance of $33,000,000 principal amount of noninterest-
   bearing subordinated convertible debentures in January 1994. Interest
   expense increased to $375,000 in 1994 from $94,000 in 1993. Interest
   expense relating to the amortization of deferred issuance costs associated
   with the debentures issued in January 1994 more than offset the decrease in
   interest expense due to the conversion of $1,920,000 principal amount of a
   4% subordinated convertible note in the second half of 1993.

   Liquidity and Capital Resources

   Working capital, including cash, cash equivalents, and short-term
   available-for-sale investments, was $60,383,000 at December 30, 1995,
   compared with $44,121,000 at December 31, 1994. Cash, cash equivalents, and
   short- and long-term available-for-sale investments were $90,474,000 at
   December 30, 1995, compared with $84,389,000 at December 31, 1994. During
   1995, $3,251,000 of cash was provided by operating activities and the
   Company expended $1,063,000 on purchases of machinery, equipment and
   leasehold improvements.
        In 1996, the Company expects to make capital expenditures of
   approximately $1,500,000, principally for manufacturing and tooling
   equipment and leasehold improvements for the continued development and
   production of the Company's LVAS. The Company believes it has adequate
   resources to meet its financial needs for the foreseeable future.
