                                     PART I

   Item 1. Business

   (a)  General Development of Business

        The businesses of Thermedics Inc. (the Company or the Registrant) are
   divided into two segments: Instruments and Other Equipment, and Biomedical
   Products. The Company's Instruments and Other Equipment segment includes
   Thermo Sentron Inc. (Thermo Sentron), a newly formed subsidiary of the
   Company. On January 2, 1996, the Company transferred to Thermo Sentron the
   assets, liabilities and business of Ramsey Technology, Inc., which was
   acquired in March 1994, for 7,000,000 shares of Thermo Sentron common
   stock. Thermo Sentron designs, develops, manufactures, and sells high-speed
   precision weighing and inspection equipment for industrial production and
   packaging lines. On February 1, 1996, Thermo Sentron filed a registration
   statement under the Securities Act of 1933 with the Securities Exchange
   Commission covering shares of common stock to be offered in its initial
   public offering. Also part of the Instruments and Other Equipment segment
   is the Orion laboratory products division (Orion) of Analytical Technology,
   Inc., which the Company acquired in December 1995 for approximately $52.7
   million in cash, which included the repayment of $8.6 million of debt,
   subject to a post-closing adjustment. To partially finance this
   acquisition, the Company borrowed $38.0 million from Thermo Electron
   Corporation (Thermo Electron) pursuant to a promissory note due December
   1996. The balance of the purchase price was funded from the Company's
   working capital. Orion is a manufacturer of electrochemistry,
   microweighing, process and other instruments used to analyze the chemical
   compositions of foods, beverages, and pharmaceuticals and detect
   contaminants in environmental and high-purity water samples. The
   Instruments and Other Equipment segment, through its Thermedics Detection
   Inc. (Thermedics Detection) subsidiary also develops, manufactures, and
   markets high-speed detection instruments, including the Alexus(R) system, a
   process detection instrument used in product quality assurance
   applications, and the EGIS(R) system, a security instrument used to detect
   explosives at airports and other locations. In January 1996, Thermedics
   Detection acquired the assets of Moisture Systems Corporation and certain
   affiliated companies (collectively, MSC), and the stock of Rutter & Co.
   (Rutter) for a total of $20.5 million in cash and the assumption of certain
   liabilities. MSC and Rutter design, manufacture, and sell instruments which
   use near infrared radiation to measure moisture for protein and other
   product components in the manufacturing process for the food,
   pharmaceutical, chemical, wood, pulp, paper, and other industries. Through
   the Company's Thermo Voltek Corp. (Thermo Voltek) subsidiary, the
   Instruments and Other Equipment segment manufactures a line of electronic
   test instruments and high-voltage power conversion systems.

        As part of its Biomedical Products segment, the Company's Thermo
   Cardiosystems Inc. (Thermo Cardiosystems) subsidiary has developed two
   implantable left ventricular-assist systems (LVAS): an implantable
   pneumatic, or air-driven system, and an electric version. In October 1994,
   the Company announced that the U.S. Food and Drug Administration (FDA)
   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 U.S. The Company also
   develops, manufactures, and markets enteral nutrition-delivery systems and
   a line of medical-grade polymers used in medical disposables and
   nonmedical, industrial applications, including safety glass and automotive
   coatings.
                                   2PAGE
<PAGE>
        The Company was incorporated in 1983 under the laws of Massachusetts
   as a wholly owned subsidiary of Thermo Electron. Prior to that time, the
   business of the Company was conducted by the R & D/New Business Center of
   Thermo Electron. As of December 30, 1995, Thermo Electron owned 17,315,326
   shares of the Company's common stock, representing 51% of such stock
   outstanding. In January 1996, the Company issued 1,688,161 shares of its
   common stock to Thermo Electron in exchange for 315,199 shares of Thermo
   Voltek common stock and 529,965 shares of Thermo Cardiosystems common
   stock. The shares of common stock were exchanged at their respective fair
   market values on the date of the transaction. 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 specialized products. Thermo
   Electron also provides environmental and metallurgical services and
   conducts advanced technology research and development.

        Thermo Electron intends, for the foreseeable future, to maintain at
   least 50% ownership of the Company. This may require the purchase by Thermo
   Electron of additional shares of common stock of the Company (or debentures
   convertible into common stock) from time to time as the number of
   outstanding shares issued by the Company increases. These or any other
   purchases may be made either in the open market or directly from the
   Company. See Notes 4 and 8 to Consolidated Financial Statements in the
   Company's 19951 Annual Report to Shareholders for a description of
   outstanding stock options and convertible debentures issued by the Company.
   During 1995, Thermo Electron purchased 484,300 shares of the Company's
   common stock in the open market at a total price of $8,632,000.

        As of December 30, 1995, the Company owned 52% and 50% of the
   outstanding common stock of Thermo Cardiosystems and Thermo Voltek,
   respectively. After the completion of Thermo Sentron's initial public
   offering, the Company is expected to own approximately 74% of Thermo
   Sentron's common stock. The Company intends, for the foreseeable future, to
   maintain at least 50% ownership of Thermo Cardiosystems, Thermo Voltek, and
   Thermo Sentron. This may require the purchase by the Company of additional
   shares of common stock or, if applicable, convertible debentures (which are
   then converted) of these companies from time to time, if the number of the
   companies' outstanding shares increases, whether as a result of conversion
   of convertible obligations or exercise of stock options issued by them, or
   otherwise. These or any other purchases by the Company may be made either
   in the open market or directly from Thermo Cardiosystems, Thermo Voltek,
   Thermo Sentron or Thermo Electron or pursuant to the conversion of all or
   part of the $7,500,000 principal amount 6 3/4% subordinated convertible
   note due 2002 and the $4,000,000 principal amount 5% subordinated
   convertible note due 2003 issued by Thermo Voltek to the Company,
   convertible into shares of Thermo Voltek's common stock at conversion
   prices of $6.40 and $5.67 per share, respectively. In addition, at December
   30, 1995, Thermo Cardiosystems and Thermo Voltek had outstanding (i) stock
   options and warrants exercisable for 798,000 and 511,000 shares,
   respectively, at various prices and subject to various vesting schedules,
   and (ii) convertible debentures (other than those held by the Company)
   convertible into 535,511 shares and 2,148,085 shares, respectively. During
   1995, the Company purchased 21,300 shares of Thermo Voltek common stock in
   the open market at a total price of $179,000.

        Financial information concerning the Company's industry segments is
   summarized in Note 14 to Consolidated Financial Statements in the
   Registrant's 1995 Annual Report to Shareholders and is incorporated herein
   by reference.

   (c)  Description of Business

        (i) Principal Products and Services

   Instruments and Other Equipment

        Precision Weighing and Inspection Equipment. Through its Thermo
   Sentron subsidiary, the Company designs, develops, manufactures, and sells
   high-speed precision weighing and inspection equipment for industrial
   production and packaging lines. Thermo Sentron serves two principal
   markets: packaged goods and bulk materials. Thermo Sentron's products for
   the packaged goods market include a wide range of checkweighing equipment
   and metal detectors that can be integrated at various stages in production
   lines for process control and quality assurance. These products are sold
   primarily to customers in the food processing and pharmaceutical
   industries. Products in Thermo Sentron's bulk-material line include
   conveyor belts, scales, solids level measurement and conveyor monitoring
   devices, and sampling systems. These products are sold primarily to
   customers in the mining and material processing industries, as well as
   electric utilities, chemical, and other manufacturing companies.

        During 1995 and 1994, the Company derived revenues of $67.5 million
   and $50.1 million, respectively, from its precision weighing and inspection
   equipment.
                                   4PAGE
<PAGE>
        Laboratory Products. To expand its product quality assurance
   offerings, the Company acquired Orion in December 1995. Through Orion, the
   Company manufactures and markets electrochemistry, microweighing, process,
   and other instruments used to analyze the chemical composition in foods,
   beverages, and pharmaceuticals and detect contaminants in environmental and
   high-purity water samples. Orion's laboratory products include ion and
   moisture analysis and precision weighing systems. Orion's laboratory
   pH/ion-selective products, marketed under the Orion brand name, identify
   chemical substances found in various types of solutions, including foods,
   pharmaceuticals, soils, and water. Pure water monitors, also marketed under
   the Orion name, use ion-selective technology to monitor parameters required
   for the control of high-purity water systems in power generation and other
   industrial applications. Other products include Cahn microweighing and
   moisture balances, Russell pH products, and Lear/Fischer
   filtration/moisture analysis products, all marketed under the Orion brand
   name. Orion also markets consumable products for its earlier instruments
   line. Orion had revenues of $46.3 million in fiscal 1994.

        Process Detection Instruments. In 1992, Thermedics Detection
   introduced Alexus, a high-speed product quality assurance system based on
   the Company's vapor-detection technology, for use in bottling lines in the
   carbonated beverage industry. The Company continues to develop new product
   quality assurance technologies to address the need for product quality in
   the beverage market. In 1994, the Company upgraded its Alexus systems to
   offer higher selectivity and operating efficiency and introduced the Alexus
   W10, which provides the bottled water industry with a device to help ensure
   product quality in returned water containers. In 1995, the Company
   developed a high-speed X-ray imaging system, currently being evaluated by
   several major beer companies in the U.S. and overseas, to detect liquid
   fill-levels for the beverage industry. The Company is also developing a
   high-speed gas chromatography instrument to provide laboratory-quality
   analysis in the field for process control applications. 

        The Company, through its newly acquired MSC and Rutter businesses, has
   a leading position in the market for near infrared radiation technology to
   measure moisture for protein and other product components in the
   manufacturing process for the food, pharmaceutical, chemical, wood, pulp,
   paper, and other industries. MSC and Rutter had combined revenues of $20.0
   million in 1994.

        During 1995, 1994, and 1993, the Company derived revenues from its
   process detection instrument business of approximately $16.2 million, $38.0
   million, and $34.4 million, respectively. 

        Security Instruments. Also through Thermedics Detection, the Company
   has developed a line of security instruments. The Company's TEA
   Analyzer(R), introduced in 1975, uses vapor-detection technology to analyze
   substances for nitrogen-based carcinogens. From this technology, Thermedics
   Detection developed the EGIS system, a highly sensitive vapor-detection
   instrument for screening people, baggage, packages, freight, and electronic
   equipment such as personal computers for the presence of a wide range of
   explosives, including the plastic explosives that have proven difficult to
   detect using conventional methods. The EGIS system detects ultratrace
   quantities of certain explosives and indicates the concentration and type
   of explosive detected. The EGIS system is in use in 21 countries and
   operational in 40 international airports, and is also used in government
   buildings, embassies, and other locations where there is a high degree of
   concern for security. The EGIS system has assisted in identifying
   explosives used in terrorist bombings, including those in Oklahoma City 
                                   5PAGE
<PAGE>
   and at the World Trade Center in New York, as well as in Israel, Buenos
   Aires, and the United Kingdom.

        Electronic Test Instruments. Through Thermo Voltek's KeyTek Instrument
   (KeyTek) division, the Company designs, develops, and manufactures
   electronic test instruments that simulate different types of pulsed
   electromagnetic interference (pulsed EMI) in order to test electronic and
   electrical systems and components for electromagnetic compatibility (EMC).
   Pulsed EMI, which is caused by natural and man-made phenomena such as
   lightning, static electricity, and electrical power disturbances, can
   damage or disrupt the operation of any product that uses digital circuits.
   Consequently, manufacturers of electronic systems and integrated circuits
   must engineer their products for immunity to pulsed EMI. The Company's
   products are used by these customers primarily for product development,
   design verification, and quality assurance, enabling them to meet higher
   levels of product performance, reliability, and safety, and to meet
   increasingly stringent regulatory requirements, including a European Union
   (EU) directive that took effect on January 1, 1996.

        Thermo Voltek instruments that test products for immunity to pulsed
   EMI fall into two main categories: (1) equipment to test electronic
   products such as computers and (2) equipment to test individual electronic
   components such as integrated circuits. This subsidiary's products also
   test for immunity to certain types of power quality failure, which include
   voltage swells, dips, and interruptions on power lines. 

        On March 1, 1995, as part of its strategy to address additional
   segments of the EMC testing market, Thermo Voltek acquired substantially
   all of the assets, subject to certain liabilities, of Kalmus Engineering
   Incorporated (Kalmus), a manufacturer of radio frequency (RF) power
   amplifiers. RF power amplifiers are used to test products for immunity to
   conducted and radiated RF interference, another form of electromagnetic
   interference, and are purchased by many of the same customers that purchase
   Thermo Voltek's pulsed EMI testing products. In addition, RF power
   amplifiers are used in a variety of laboratory and test applications where
   precise control over power level and frequency are required; in medical
   imaging applications; and in wireless communications applications, such as
   in cellular telephone systems, wireless wide area networks (WANs) and local
   area networks (LANs), and mobile data communications. 

        Through Thermo Voltek's Comtest subsidiary, the Company provides
   EMC-consulting and systems-integration services, acts as distributor of a
   broad range of EMC-testing products, and manufactures specialized power
   supplies for use in telecommunications equipment.

        During 1995, 1994, and 1993, the Company derived revenues of $31.6
   million, $19.0 million, and $13.2 million, respectively, from electronic
   test instruments.

        High-voltage Systems. Through Thermo Voltek's Universal Voltronics
   division, the Company designs, manufactures, and markets high-voltage power
   conversion systems, modulators, fast-response protection systems, and
   related high-voltage equipment for industrial, medical, and environmental
   processes, and defense and scientific research applications. These systems
   transform utility-supplied voltage and current into the high voltage or
   current required by the user and allow precise control over the performance
   level desired for each application. The Company's systems produce power
   ranging from 1,000 to 1,000,000 volts, and range in size from small systems
                                   6PAGE
<PAGE>
   used in benchtop instruments to room-sized systems used in scientific
   research applications.

        The Company currently sells products on an OEM (original equipment
   manufacturer) basis for use in commercial applications, which include
   electrostatic coating and separation, industrial and medical lasers, and
   electron-beam applications. In addition, the Company has developed
   high-voltage power supplies for microwave-driven light sources used to test
   projection televisions during the manufacturing process.

   Biomedical Products

        Left Ventricular-assist Systems. The Company, through its Thermo
   Cardiosystems subsidiary, has developed two versions of its LVAS: an
   implantable pneumatic (IP), 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. These 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. Both of the Company's
   systems employ the Company's HeartMate(R) blood pump and are designed for
   long-term use. This pump incorporates proprietary technological advances in
   biological compatibility that distinguish it from other competitive
   devices, including proprietary textured linings that can significantly
   reduce the likelihood of blood clots that can lead to strokes.

        Unlike a total artificial heart system, which requires removal of the
   natural heart, the LVAS allows the natural heart to remain 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 and also provides the important
   psychological advantage of not removing the organ.

        IP LVAS. The Company announced in October 1994, that the IP LVAS
   system had been approved by the FDA for commercial sale for use as a
   bridge-to-transplant. This approval allows the Company to sell the IP LVAS
   to any of the nearly 900 cardiac surgery centers in the United States. In
   April 1994, the Company received the European Conformity Mark (CE Mark),
   which allows commercial sale of the air-driven LVAS in all European
   Community countries. The IP LVAS 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 the Company's IP LVAS to patients. In addition,
   Thermo Cardiosystems is working with nearly 30 cardiac sites in such
   countries as the United Kingdom, Germany, Sweden, Japan, the Netherlands,
   France, Italy, and Belgium. In November 1995, the U.S. Health Care Finance
   Administration (HCFA) issued a decision that extends Medicare coverage to
                                   7PAGE
<PAGE>
   Thermo Cardiosystems' IP LVAS. Several major nongovernment insurers,
   including Blue Cross/Blue Shield of Connecticut, Aetna Life & Casualty
   Company (Aetna) and the health maintenance organization (HMO) U.S.
   Healthcare, have already agreed to offer coverage for the IP LVAS.
   Additional insurers are reviewing the clinical results with the device, and
   additional coverage decisions will be forthcoming.

        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 an external battery
   pack by wires that exit the body, allowing the patient complete mobility. 

        In early 1991, the Company received an investigational device
   exemption (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 April
   1993, the FDA granted approval to allow patients with an electric LVAS to
   be discharged from the hospital with their physician's approval, improving
   quality of life and reducing 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. 

        Medical Grade Polymers and Enteral Nutrition-Delivery Systems. The
   Company's research relating principally to the development of its LVAS has
   resulted in the development of proprietary medical-grade plastics marketed
   under the names Tecoflex(R) and Tecothane(R). Tecoflex and Tecothane are
   thermoplastic polyurethanes used in medical disposables and industrial
   products. The Company sells Tecoflex and Tecothane in bulk form for
   fabrication by the customer, and the Company also extrudes precision tubing
   to customer specifications. Tecoflex and Tecothane can be custom-fabricated
   to a variety of shape, size, hardness, color, and opacity specifications.

        Tecoflex and Tecothane are used by medical-products companies to
   fabricate products such as catheters and tubing for drug-delivery systems,
   enteral nutrition-delivery systems, fluid transfer systems, and diagnostic
   devices. In addition, due to the strength, weather resistance, and optical
   clarity of these polyurethanes, they are used by industrial customers for
   aerospace and safety glass applications.

        The Company introduced Scent Seal fragrance samplers, which were
   developed from the Company's polymer technology, in 1993. Scent Seal
   fragrance samplers are used to hermetically seal a fragrance rendition in
   perfume advertisements for magazines, and are an alternative to commonly
   used fragrance strips.
                                   8PAGE

        In June 1995, Thermedics entered into an agreement granting Arcade,
   Inc., the leading manufacturer of scent-sampling products, an exclusive,
   worldwide license to manufacture and distribute the Company's fragrance
   samplers under Thermedics' patents and know-how. The license arrangement
   follows the termination of Thermedics' exclusive marketing agreement with
   Scent Seal, Inc., and the acquisition of Scent Seal, Inc. by Arcade. Under
   the license agreement, Arcade pays royalties to Thermedics on licensed
   fragrance samplers sold by Arcade, and Thermedics continues to provide the
   polymer gels needed to produce the fragrance samplers. Arcade pays
   Thermedics royalties of approximately five percent of revenues from the
   licensed samplers, with minimum annual royalty payments required to
   maintain an exclusive license.

        The Company's Corpak Inc. (Corpak) subsidiary designs, manufactures,
   and markets enteral feeding systems that introduce special nutritional
   solutions into the stomach or the small intestine through tubes entering
   the nose or stomach. Enteral therapy is used for patients who are unable to
   feed themselves but who do not require parenteral (intravenous) feeding.
   Corpak's products include bags for nutritional fluids, delivery pumps,
   associated pump sets that hook up to the pumps, and feeding tubes. In
   addition, Corpak markets a range of enteral feeding supplements.

        (ii) New Products

        The Company's business includes the development and introduction of
   new products in the following categories:  precision measurement and
   inspection equipment, process detection instruments, security instruments,
   electronic test instruments, high-voltage systems, left ventricular-assist
   systems, and biomaterials. The Company also develops electrochemistry,
   microweighing, and other laboratory instruments through its recently
   acquired Orion subsidiary.

        (iii) Raw Materials

        The Company has a number of sole-source suppliers. A number of the
   components of the Company's EMC-testing products are supplied by
   sole-source vendors. The Company also relies upon one supplier as a sole
   source of one of the chemical components used in the manufacture of one of
   its polyurethanes. To date, the Company has experienced no difficulties in
   obtaining these materials and components. 

        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 have 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.
                                   9PAGE
<PAGE>
        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 considers its intellectual property important in the
   operation and growth of its business, and its policy is to protect this
   property through patents, license and confidentiality agreements,
   trademarks, and trade secret protection. The Company applies for and
   maintains patents in the U.S. and in foreign countries, particularly in the
   areas of biomedical materials, medical products, and analytical
   instruments. 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. In April 1995, Thermo Cardiosystems received
   correspondence from a third party alleging that the textured surface of the
   LVAS housing infringed certain patent rights of such third party. Thermo
   Cardiosystems had previously received similar correspondence from this
   third party but had not received any communication for more than three
   years. In its April 1995 communication, the third party offered Thermo
   Cardiosystems a license, which Thermo Cardiosystems has elected not to
   accept. Although Thermo Cardiosystems 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 Thermo Cardiosystems would be successful were
   any litigation to be commenced.

        The Company also has certain licenses to the technology resulting from
   its customer-sponsored development of a high-speed detection system for
   product quality assurance. The patents and agreements of the Company have
   varying lives ranging from one year to approximately 20 years, and the
   Company does not believe that the expiration or termination of any one of
   these patents or agreements would materially affect the Company's business.

     (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.
                                   10PAGE
<PAGE>
     (vii) Dependency on a Single Customer

        No customer represented 10% or more of the Company's total revenues in
   1995. The Company derived 21% and 43% of its total revenues in 1994 and
   1993, respectively, from The Coca-Cola Company and its affiliates. The
   Company derived 5% of its total revenues in 1994 from Scent Seal Inc.,
   which represented 23% of the Biomedical Products segment revenues.

     (viii) Backlog

        The Company's backlog of firm orders at year-end 1995 and 1994 was as
   follows:

   (In thousands)                                            1995      1994
   ------------------------------------------------------------------------

   Instruments and Other Equipment                        $31,800   $26,200
   Biomedical Products                                      2,200     3,700
                                                          -------   -------
                                                          $34,000   $29,900
                                                          =======   =======

        The Company anticipates that substantially all of the backlog at the
   end of 1995 will be shipped or completed during fiscal 1996.

        (ix) Government Contracts

        Not applicable.

        (x) Competition

        In general, the Company competes with other entities on the basis of
   technological advances, particularly with respect to the Company's work in
   analytical instruments and biomedical devices.

   Instruments and Other Equipment

        Precision Weighing and Inspection Equipment.  The Company's Thermo
   Sentron subsidiary competes with several international and regional
   companies in the market for its products. Thermo Sentron's competitors in
   the packaged goods market differ from those in the bulk materials market.
   The principal competitive factors in both markets are customer service and
   support, quality, reliability, and price.

        Laboratory Products. The Company's Orion division competes with
   several international companies. In the markets for the products made by
   its Orion division, the Company competes on the basis of performance,
   service, technology, and price.

        Process Detection Instruments. The Company's product quality assurance
   systems compete with chemical-detection systems manufactured by several
   companies using similar technology as well as other technologies and
   processes for product quality assurance. Competition in the markets for all
   of the Company's detection products is based primarily on performance,
   service, and price.
                                   11PAGE
<PAGE>
        Security Instruments. In the security instruments market, the Company
   competes with a small number of companies that include makers of other
   chemical-detection instruments as well as enhanced X-ray detectors. Since
   the Federal Aviation Administration (FAA) has not required that U.S.
   airports and airlines buy advanced explosives-detection equipment, the
   Company has not sold any EGIS systems to U.S. airlines. The Company
   believes that the companies, if any, whose devices are required by the FAA
   will have a substantial competitive advantage in the United States. In
   December 1994, the FAA approved the use of an X-ray imaging system
   developed by InVision Technologies in Foster City, California, indicating
   that the FAA is currently focusing its attention on X-ray technology.

        Electronic Test Instruments. The Company is a leading supplier of
   pulsed EMI testing equipment. The Company estimates that there are
   approximately 15 companies worldwide that independently manufacture and
   market pulsed EMI test equipment for electronic products and approximately
   10 companies that independently manufacture and market component-
   reliability test equipment. The Company competes in this market primarily
   on the basis of performance, technical expertise, and reputation.

        In the market for RF power amplifiers, the Company competes with
   approximately five companies worldwide. Competition in this market is based
   primarily on the basis of technical expertise, reputation, and price.

        High-voltage Systems. The Company estimates that there are
   approximately 20 companies that independently manufacture and market
   high-voltage power supply systems of the general type manufactured and
   marketed by Thermo Voltek. Thermo Voltek competes for both contract and
   commercial sales primarily on the basis of technical expertise, product
   performance, and reputation. Substantially all of Thermo Voltek's contract
   and commercial revenues are subject to intense competitive bidding.

   Biomedical Products

        Left Ventricular-assist Systems. 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 that is 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 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
                                   12PAGE
<PAGE>
   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. Healthcare, have agreed to offer
   coverage for the IP LVAS, while many others are reimbursing on a
   case-by-case basis.

        Medical Grade Polymers and Enteral Nutrition-Delivery Systems. In the
   market for medical-grade polymers and enteral nutrition-delivery systems,
   the Company competes primarily with large pharmaceutical, medical device,
   and chemical companies, many of which have substantially greater financial,
   technical, and human resources than those of the Company. Competition
   within these markets is intense, and is based primarily on price, efficacy,
   and technological advances.

        (xi) Research and Development

        The Company maintains a research and development capability to support
   its existing products and to develop new products. A number of programs are
   under way, funded by the Company solely or jointly with an outside company.
   These programs include development of new products to perform substantially
   all or part of the pumping function of the left ventricle of the natural
   heart, process detection and security instruments, electronic test
   instruments, and high-voltage power supply products. The Company also
   develops new grades of polymers to meet specific customer requirements for
   industrial and medical applications.

        During 1995, 1994, and 1993, the Company expended $11,087,000,
   $10,445,000, and $6,434,000, respectively, on internally sponsored research
   and development programs, and $3,125,000, $1,702,000, and $2,702,000,
   respectively, on research and development programs sponsored by others. At
   December 30, 1995, 169 professional employees were engaged full-time in
   research and development activities.

        (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's Instruments and Other Equipment
   and Biomedical Products segments employed 1,095 and 277 people,
   respectively.

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

        Financial information about exports by domestic operations and about
   foreign operations is summarized in Note 14 to Consolidated Financial
   Statements in the Registrant's 1995 Annual Report to Shareholders and is
   incorporated herein by reference.

        Each executive officer serves until his successor is chosen or
   appointed and qualified or until earlier resignation, death, or removal.
   All executive officers have held comparable positions for at least five
   years either with the Company or with its parent company, Thermo Electron.
   Mr. Keiser was appointed senior vice president of the Company in 1994, at
   the same time he was named president of Thermo Biomedical, a newly created
   subsidiary of Thermo Electron. From 1985 and until 1994, Mr. Keiser was
   president of the Eberline Instrument division of Thermo Instrument Systems
   Inc., a majority-owned public subsidiary of Thermo Electron. Messrs. Wood
   and Fine are full-time employees of the Company. Messrs. Hatsopoulos and
   Kelleher are full-time employees of Thermo Electron and Mr. Poirier is a
   full-time employee of Thermo Cardiosystems, but they devote such time to
   the affairs of the Company as the Company's needs reasonably require.

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


        We have audited, in accordance with generally accepted auditing
   standards, the consolidated financial statements included in Thermedics
   Inc.'s Annual Report to Shareholders incorporated by reference in this Form
   10-K, and have issued our report thereon dated February 7, 1996 (except
   with respect to the matters discussed in Note 15 as to which the date is
   February 9, 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 17 is the responsibility of the Company's management and is
   presented for purposes of complying with the Securities and Exchange
   Commission's rules and is not part of the basic consolidated financial
   statements.  The schedule has been subjected to the auditing procedures
   applied in the audits of the basic consolidated financial statements and,
   in our opinion, fairly states in all material respects the consolidated
   financial data required to be set forth therein in relation to the basic
   consolidated financial statements taken as a whole.

        assets of the Sellers (the "Excluded Assets"):

                  (a)  The buildings and real property located at The Old
        School, Station Road, Cogenhoe, Northampton, England owned by
        MSC-UK.

                  (b)  The assets described on Exhibit B attached hereto.

             2.3  Purchase Price for the Assets.  Subject to Section 2.5,
        the aggregate purchase price for the Assets shall be $13,500,000
        (the "Purchase Price") payable as follows:  (a) $12,225,000 to
        MSC, (b) $475,000 to MSC-UK and (c) $800,000 to Anacon.

             2.4  Assumption of Liabilities.  At the Closing, the Buyer
        shall assume only the following liabilities of the Sellers (the
        "Assumed Liabilities"):  (i) liabilities reflected on the
        September Balance Sheets, except for any such liabilities
        discharged since the date of the September Balance Sheets (the
        "Balance Sheet Date") and except for liabilities excluded from
        the Draft Closing Balance Sheet pursuant to Section 2.5(a), (ii)
        liabilities incurred by the Sellers in the Ordinary Course of
        Business since the Balance Sheet Date, (iii) liabilities under
        bona fide warranty obligations of the Sellers outstanding as of
        the Closing Date, and (iv) liabilities and obligations under any
                                       11PAGE
<PAGE>

        Contract assigned to the Buyer pursuant hereto, except for any
        such liabilities or obligations resulting from the actual or
        alleged breach by any of the Sellers of any such Contracts.  In
        furtherance of, but without limiting, the foregoing, except to
        the extent reflected on the September Balance Sheets, the Assumed
        Liabilities will not include any liabilities or obligations of
        the Sellers (a) for any Environmental Health and Safety
        Liabilities resulting from the ownership, operation or condition
        of the Facilities, or for any liabilities or obligations
        resulting from any Hazardous Activity conducted on or prior to
        the Closing Date, (b) for any Taxes resulting from the conduct of
        the business of the Sellers prior to the Closing Date, (c) to any
        retired or other former employees of any of the Sellers for
        salaries or benefits accrued prior to the Closing Date, (d) under
        any agreements with any employees providing for severance
        payments in the event such employees are terminated by Buyer
        after the Closing, (e) under any employee benefit plan maintained
        by any of the Sellers, including, without limitation, the defined
        benefit plan maintained by MSC-UK or (f) payables relating to the
        dust monitor business.  The Sellers and the Buyer anticipate that
        the United Kingdom Transfer of Undertakings (Protection of
        Employment) Regulations 1981 (the "Transfer Regulations") will
        apply to the sale and purchase under this Agreement in respect of
        the UK Employees.  The Sellers and the Buyer acknowledge and
        agree that under the Transfer Regulations the contracts of
        employment between MSC-UK and the UK Employees will have effect
        after the Closing Date as if originally made between Buyer and
        the UK Employees.  This shall not, however, diminish the Sellers'
        obligations pursuant to Section 5.2 to indemnify the Buyer
        against the liabilities specified in clauses (c), (d) and (e) of
        the preceding sentence or any other liabilities not specifically
        assumed by the Buyer under this Section 2.4, in relation to the
        UK Employees or any other past or present employees of MSC-UK or
        any predecessor of MSC-UK.  Notwithstanding the foregoing, the
        Buyer acknowledges and agrees that it will be responsible for any
        severance payments imposed by statute incurred when any UK
        Employee is terminated by Buyer after the Closing.  Any
        liabilities or obligations of the Sellers that are not Assumed
        Liabilities are referred to herein as "Excluded Liabilities."

             2.5  Post-Closing Adjustments.  The Purchase Price set forth
        in Section 2.2 shall be subject to adjustment after the Closing
        Date as follows:

                  (a)  Within 60 days after the Closing Date, the Buyer
        shall prepare and deliver to the Representative balance sheets
        reflecting the net tangible assets of each Seller (each, a "Draft
        Closing Balance Sheet").  The Buyer shall prepare the Draft
        Closing Balance Sheets in accordance with GAAP.  For purposes of
        this Agreement, "net tangible assets" shall mean tangible Assets
        minus Assumed Liabilities.  Notwithstanding anything to the
        contrary herein, the Draft Closing Balance Sheets shall not
        include any liabilities for vacation time for employees of the
        Sellers accrued between June 1, 1995 and the Closing Date or any
                                       12PAGE
<PAGE>

        of the following liabilities:  (i) as described in the September
        Balance Sheet of MSC, (A) notes payable-officers, (B) accrued
        royalties payable, (C) accrued salaries-officers and (D) accrued
        dividends, (ii) as described in the September Balance Sheet of
        Anacon, (A) notes payable-officers, (B) accrued rent-related, (C)
        accrued expenses-related and (D) accrued dividends, and (iii) any
        payables from MSC-UK to Moisture Systems Consolidated Corporation
         In addition, the Draft Closing Balance Sheets shall not include
        any of the following assets as described on the September Balance
        Sheet of MSC: (i) notes receivable, (ii) interest receivable and
        (iii) rents receivable.  It is agreed that the valuation for all
        inventory on the Draft Closing Balance Sheet for Anacon shall be
        no greater than $150,000.

                  (b)  The Representative shall deliver to the Buyer
        within 60 days after receiving the Draft Closing Balance Sheets a
        detailed statement describing its objections (if any) thereto.
        Failure of the Representative so to object to any Draft Closing
        Balance Sheet shall constitute acceptance thereof, whereupon such
        Draft Closing Balance Sheet shall be deemed to be a "Closing
        Balance Sheet".  The Buyer and the Representative shall use
        reasonable efforts to resolve any such objections, but if they do
        not reach a final resolution within 30 days after the Buyer has
        received the statement of objections, the Buyer and
        Representative shall select an internationally recognized
        accounting firm mutually acceptable to them (the "Neutral
        Auditors") to resolve any remaining objections.  If the Buyer and
        Representative are unable to agree on the choice of Neutral
        Auditors, they shall select as Neutral Auditors an
        internationally recognized accounting firm by lot (after
        excluding their respective regular independent accounting firms).
        The Neutral Auditors shall determine whether the objections
        raised by the Representative are valid.  Each Draft Closing
        Balance Sheet that is the subject of objections by the
        Representative shall be adjusted in accordance with the Neutral
        Auditor's determination and, as so adjusted, shall be a Closing
        Balance Sheet.  Such determination by the Neutral Auditors shall
        be conclusive and binding upon the Buyer and Representative.  The
        Buyer, on one hand, and the Sellers, on the other, shall share
        equally the fees and expenses of the Neutral Auditors.

                  (c)  If the net tangible assets as shown on the Closing
        Balance Sheet applicable to any Seller is less than the Net Asset
        Benchmark for such Seller, such Seller shall pay to the Buyer, by
        wire transfer in immediately available funds, within ten business
        days after the date on which the Closing Balance Sheet is finally
        determined pursuant to this Section 2.5, an amount equal to such
        deficiency (plus interest thereon from the Closing Date at the
        interest rate equal to the base rate of the Bank of Boston as
        announced from time to time).

                  (d)  If the net tangible assets as shown on the Closing
        Balance Sheet applicable to any Seller is more than the Net Asset
        Benchmark for such Seller, the Buyer shall pay to such Seller, by
                                       13PAGE
<PAGE>

        wire transfer in immediately available funds, within ten business
        days after the date on which the Closing Balance Sheet is finally
        determined pursuant to this Section 2.5, an amount equal to such
        excess (plus interest thereon from the Closing Date at the
        interest rate equal to the base rate of Bank of Boston as
        announced from time to time).

                  (e)  As used in this Section 2.5, "Net Asset Benchmark"
        means (i) with respect to MSC, $2,415,000, (ii) with respect to
        MSC-UK, $313,500 and (iii) with respect to Anacon, $250,000.

             2.6  Allocation of Purchase Price.  The final allocation of
        the Purchase Price among the Assets shall reflect the book value
        of the Assets as shown on the Closing Balance Sheets.  The Buyer
        and the Sellers each shall report the federal, state, provincial,
        foreign and local income and other tax consequences of the
        transaction contemplated hereby in a manner consistent with such
        allocation.

             2.7  The Closing.  The closing of the transactions
        contemplated by this Agreement (the "Closing") shall occur at the
        offices of Thermo Electron Corporation, 81 Wyman Street, Waltham,
        Massachusetts, at 10:00 a.m. on the date set forth in the first
        paragraph of this Agreement (the "Closing Date").

             2.8  Deliveries by the Sellers to the Buyer.  At the
        Closing, the Sellers shall deliver, or cause to be delivered, to
        the Buyer, or any Subsidiary of the Buyer designated by the Buyer
        for this purpose:

                  (a)  such executed assignments, patent assignments,
        trademark assignments, bills of sale, certificates of title, or
        other documents, each dated the Closing Date, as shall be
        necessary, in the reasonable opinion of Buyer and its counsel to
        transfer to the Buyer all of the Sellers' right, title and
        interest in and to the Assets; and

                  (b)  an opinion of Bingham, Dana & Gould, counsel to
        the Sellers, in the form attached hereto as Exhibit C;

                  (c)  consents to the assignment of the Contracts listed
        on Exhibit D; and

                  (d)  the Lease.

             2.9  Deliveries by the Buyer to the Sellers.  At the
        Closing, the Buyer shall deliver to the Sellers:

                  (a)  the Purchase Price less the retention described in
        Section 2.10 by wire transfer to the account(s) designated by the
        Sellers; and

                  (b)  an executed assumption agreement and such other
        documents, each dated as of the Closing Date, as shall be
                                       14PAGE
<PAGE>

        necessary, in the reasonable opinion of the Sellers and their
        counsel, for the assumption by the Buyer of all of the Assumed
        Liabilities.

                  (c)  an opinion of Seth H. Hoogasian, general counsel
        of the Buyer, in the form attached hereto as Exhibit E.

             2.10 Escrow.  For the purpose of providing security for the
        obligations of the Sellers and the Principals under section 5.2,
        $1,350,000 (the "Escrow Amount") shall be withheld from the
        Purchase Price delivered at Closing and shall be placed in an
        escrow account with  an escrow agent (the "Agent") satisfactory
        to the parties.  On the first anniversary of the Closing Date,
        the Representative may withdraw for distribution to the Sellers,
        as their interests appear, 50% of the Escrow Amount, together
        with interest earned on such portion, less the amount of any
        unsatisfied claims for indemnification made by the Buyer prior to
        such first anniversary.  On the second anniversary of the
        Closing, the Representative may withdraw the remainder of the
        Escrow Amount, together with any interest thereon, for
        distribution to the Sellers, as their interests appear, less the
        amount of any unsatisfied claims for indemnification made by the
        Buyer on or prior to such second anniversary.  Any portion of the
        Escrow Amount that cannot be withdrawn from the escrow account
        due to pending claims by the Buyer for indemnification, shall
        remain in the escrow account until the resolution of such claims
        by judgment of a court from which no appeal can be made, decision
        of an arbitrator or agreement of the Buyer and the
        Representative.

        3.   REPRESENTATIONS AND WARRANTIES OF THE SELLERS

             The Sellers represent and warrant to Buyer as follows:

             3.1  Organization and Good Standing.

                  (a)  Each of the Sellers is a corporation duly
        organized, validly existing, and in good standing under the laws
        of the state or other jurisdiction of its incorporation or
        organization, with full corporate power and authority to conduct
        its business as it is now being conducted, to own or use the
        properties and assets that it purports to own or use, and to
        perform all its obligations under Applicable Contracts.  Each of
        the Sellers is duly qualified to do business as a foreign
        corporation and is in good standing under the laws of each state
        or other jurisdiction in which either the ownership or use of the
        properties owned or used by it, or the nature of the activities
        conducted by it, requires such qualification, except where the
        failure to so qualify, individually or in the aggregate, would
        not have a Material Adverse Effect.

                  (b)  Each of the Sellers has delivered to Buyer copies
        of its Organizational Documents, as currently in effect.

                                       15PAGE
<PAGE>

             3.2  Authority; No Conflict.

                  (a)  This Agreement constitutes the legal, valid, and
        binding obligations of the Sellers, enforceable against them in
        accordance with its terms.  

                  (b)  Except as set forth in Part 3.2 of the Disclosure
        Letter, neither the execution and delivery of this Agreement nor
        the consummation or performance of any of the Contemplated
        Transactions will, directly or indirectly (with or without notice
        or lapse of time):  (i) contravene, conflict with, or result in a
        violation of (A) any provision of the Organizational Documents of
        any of the Sellers, or (B) any resolution adopted by the board of
        directors or the stockholders of any of the Sellers; (ii)
        contravene, conflict with, or result in a violation of, or give
        any Governmental Body or other Person the right to challenge any
        of the Contemplated Transactions or to exercise any remedy or
        obtain any relief under, any Legal Requirement or any Order to
        which any of the Sellers, or any of the assets owned or used by
        any of the Sellers, may be subject; (iii) contravene, conflict
        with, or result in a violation or breach of any provision of, or
        give any Person the right to declare a default or exercise any
        remedy under, or to accelerate the maturity or performance of, or
        to cancel, terminate, or modify, any Applicable Contract; (iv)
        result in the imposition or creation of any Encumbrance upon or
        with respect to any of the assets owned or used by any of the
        Sellers; or (v) entitle any employee or other person to severance
        or other payments by any of the Sellers or create any other
        obligation to an employee or other person, including any increase
        in benefits.

                  (c) Except as set forth in Part 3.2 of the Disclosure
        Letter, none of the Sellers will be required to give any notice
        to or obtain any Consent from any Person in connection with the
        execution and delivery of this Agreement or the consummation or
        performance of any of the Contemplated Transactions.

             3.3  Subsidiaries.  Set forth in Part 3.3 of the Disclosure
        Letter is a list of all Subsidiaries of the Sellers, including,
        with respect to each Subsidiary, its jurisdiction of
        incorporation.  All of the outstanding capital stock of each
        Subsidiary has been duly authorized and validly issued, is fully
        paid, nonassessable and free of preemptive rights, and is owned
        beneficially and of record by the respective Seller or by another
        Subsidiary of a Seller free and clear of any Encumbrance or
        restriction of any nature, including, without limitation, any
        restriction on transfer or voting.  No shares of any Subsidiary's
        capital stock are reserved for issuance, and there are no
        options, warrants, convertible instruments or other rights,
        agreements or commitments, contingent or otherwise, obligating a
        Subsidiary to issue, sell or purchase shares of capital stock.
        None of the Sellers is a partner or joint venturer with any other
        person.  None of the Sellers is subject to any obligation,
        contingent or otherwise, to provide funds to or make an
                                       16PAGE
<PAGE>

        investment (in the form of a loan, capital contribution or
        otherwise) in any entity.  None of the Sellers has any equity
        interest in any corporation, partnership or other business entity
        other than the Subsidiaries listed on the Disclosure Letter.
        Each Subsidiary is in good standing under the laws of its
        jurisdiction of incorporation and has all requisite power and
        authority to own, operate and lease its properties and to carry
        on its business as it is now being conducted.  The Sellers have
        delivered to Buyer complete and correct copies of the
        Organizational Documents of each Subsidiary, as amended.  Each
        Subsidiary is duly qualified as a foreign corporation to do
        business, and is in good standing, in each jurisdiction in which
        the character of the properties owned, operated or leased by it
        or the nature of its activities is such that qualification is
        required by applicable laws, except where the failure to so
        qualify would not, individually or in the aggregate, have a
        Material Adverse Effect.  All jurisdictions where the
        Subsidiaries are qualified as foreign corporations or are
        required to be so qualified are listed on Part 3.3 of the
        Disclosure Letter.

             3.4  Financial Statements.  Each Seller has delivered to
        Buyer:  (a) an unaudited consolidated balance sheet of such
        Seller as at December 31, 1994 (each a "1994 Balance Sheet"), and
        the related unaudited statement of income and cash flows for the
        fiscal year then ended (each a "1994 Income Statement") and (b)
        an unaudited balance sheet of such Seller as at September 31,
        1995 (each a "September Balance Sheet") and the related unaudited
        statement of income and cash flows for the nine months then ended
        (each a "September Income Statement").  The 1994 Balance Sheets,
        September Balance Sheets, 1994 Income Statements and September
        Income Statements are referred to collectively as the "Financial
        Statements".  The Financial Statements fairly present the
        financial condition and the results of operations and cash flows
        of the Sellers as at the respective dates of and for the periods
        referred to therein all in accordance with GAAP, except that the
        September Balance Sheets are subject to normal year-end
        adjustments.  The Financial Statements reflect the consistent
        application of such accounting principles throughout the periods
        involved.  

             3.5  Books and Records.  The books of account, minute books,
        and other records of the Sellers, all of which have been made
        available to Buyer, are complete and correct in all material
        respects.  

             3.6  Title to Properties; Encumbrances.  Except as set forth
        in part 3.6 of the Disclosure Letter, the Sellers have valid and
        legally enforceable title to all of the Assets free and clear of
        any Encumbrances whatsoever, and the consummation of the
        Contemplated Transactions will vest in Buyer all of the Sellers'
        right, title and interest in and to the Assets.

             3.7  Accounts Receivable.  All accounts receivable of the
        Sellers that are reflected on the September Balance Sheets
        (except for those collected in full prior to the Closing Date) or
        on the accounting records of the Sellers as of the Closing Date
        (collectively, the "Accounts Receivable") represent or will
        represent valid obligations arising from sales actually made or
        services actually performed in the Ordinary Course of Business.
        Unless paid prior to the Closing Date and except as set forth on
        Part 3.7 of the Disclosure Letter, to the Knowledge of the
        Sellers, the Accounts Receivable are or will be as of the Closing
        Date current and collectible net of the respective reserves shown
        on the September Balance Sheets or on the accounting records of
        the Sellers as of the Closing Date.  Except as set forth on Part
        3.7 of the Disclosure Letter, none of the Sellers has received
        notice that there is any contest, claim, or right of set-off with
        any maker of an Account Receivable relating to the amount or
        validity of such Account Receivable.  The Sellers do not have any
        accounts receivable from Moisture Systems Consolidated
        Corporation and MSC does not have any accounts receivable from
        MSC-UK which were assigned to MSC from Moisture Systems
        Consolidated Corporation.

             3.8  Taxes.  Except as set forth in Part 3.8 of the
        Disclosure Letter:

                  Each of the Sellers has accurately prepared and duly
        and timely filed all Tax Returns that it was required to file.
        All such Tax Returns were correct and complete in all material
        respects.  All Taxes owed by the Sellers have been paid when due,
        other than those being contested in good faith and where adequate
        reserves (determined in accordance with GAAP) have been
        established therefor.  All Taxes of any of the Sellers
        attributable to Tax periods or portions thereof ending on or
        prior to the Closing Date, including Taxes that may become
        payable by any of the Sellers in future periods in respect of any
        transactions or sales occurring on or prior to the Closing Date,
        that have not yet been paid have, in the aggregate, been
        adequately reflected as a liability on the books of the Sellers
        in accordance with GAAP.  None of the Sellers is currently being
        audited or examined by any Governmental Body, nor have any
        deficiencies for any Tax been asserted against any of the
        Sellers.  No claim or inquiry with respect to any material amount
        of Taxes has been made within the past seven years by an
        authority in a jurisdiction where any of the Sellers did not file
        Tax Returns that it is or may be subject to any Tax by that
        jurisdiction.  Without limiting the generality of the foregoing,
        each of the Sellers has withheld or collected and duly paid all
        Taxes required to have been withheld or collected and paid in
        connection with payments to foreign persons, sales and use Tax or
        Value Added Tax obligations, and amounts paid or owing to any
        employee, independent contractor, creditor, stockholder or other
        person.

             3.9  Employee Benefits.  Part 3.9 of the Disclosure Letter
        contains a true, correct and complete list of all benefit plans
        (as defined in Section 3(3) of ERISA) and all pension, benefit,
        profit sharing, retirement, deferred compensation, welfare,
        insurance, disability, bonus, vacation pay, severance pay and
        other similar plans, programs and agreements, whether reduced to
        writing or not, relating to any of the employees of any of the
        Sellers (the "Plans") and, except as set forth in Part 3.9 of the
        Disclosure Letter,  none of the Sellers has any obligations,
        contingent or otherwise, past or present, under applicable law or
        the terms of any Plan.  With respect to all Plans, each of the
        Sellers is in compliance with all applicable Legal Requirements,
        including ERISA.  Each of the Sellers has performed all material
        obligations required to be performed by it under, and is not in
        material violation of, and there has been no material default or
        violation by any other party with respect to, any of the Plans.
        There are no pending or, to the Knowledge of the Sellers,
        Threatened Proceedings by employees or former employees of any of
        the Sellers, or beneficiaries or spouses of any of the above,
        involving any Plan (other than routine, undisputed claims for
        benefits).  The Sellers have provided the Buyer with copies of
        each Plan that is in writing and with a written summary of each
        oral Plan.  Except for MSC's 401(k) plan, no Plan is an "employee
        pension benefit plan" as such term is defined in Section 3(2) of
        ERISA.  None of the Sellers nor any ERISA Affiliate (as defined
        below) contributes to or has an obligation to contribute to or
        has contributed to or had an obligation to contribute to within
        the past six years, a "multiemployer" plan as defined in Section
        4001(a)(3) of ERISA.  None of the Sellers nor any ERISA Affiliate
        has withdrawn from a multi-employer plan in a complete or partial
        withdrawal that resulted in any unsatisfied employer liability.
        None of the Sellers contributes to an employee pension benefit
        plan that is subject to Section 412 of the Code or Title IV of
        ERISA.  "ERISA Affiliate" means an entity which is a member of
        (i) a controlled group of corporations (as defined in Section
        414(b) of the Code), (ii) a group of trades or businesses under
        common control (as defined in Section 414(c) of the Code), or
        (iii) an affiliated service group (as defined in Section 414(m)
        of the Code or the regulations under Section 414(o) of the Code),
        any of which includes any of the Sellers.

        Requirement that is or was applicable to it or to the conduct or
        operation of its business or the ownership or use of any of its
        assets; (ii) no event has occurred or circumstance exists that
        (with or without notice or lapse of time) may constitute or
        result in a violation by any of the Sellers of, or a failure on
        the part of any of the Sellers to comply with, any Legal
        Requirement; (iii)  none of the Sellers has received, at any time
        since January 1, 1991, any notice or other communication (whether
                                       19PAGE
<PAGE>

        oral or written) from any Governmental Body or any other Person
        regarding any actual, alleged, possible, or potential violation
        of, or failure to comply with, any Legal Requirement.
        Notwithstanding anything herein to the contrary, the Sellers make
        no representation or warranty with respect to the applicability
        of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
        amended, to the Contemplated Transactions.

                  (b)  The Sellers have obtained all Governmental
        Authorizations necessary for the conduct of their respective
        businesses as currently conducted.  Except as set forth in Part
        3.10 of the Disclosure Letter:  (i) each of the Sellers is, and
        at all times since January 1, 1991 has been, in  compliance in
        all material respects with each such Governmental Authorization,
        (ii) no event has occurred or circumstance exists that may (with
        or without notice or lapse of time) constitute or result directly
        or indirectly in a violation of or a failure to comply with any
        term or requirement of any such Governmental Authorization; (iii)
        none of the Sellers has received, at any time since January 1,
        1991, any notice or other communication (whether oral or written)
        from any such Governmental Body or any other Person regarding (A)
        any actual, alleged, possible, or potential violation of or
        failure to comply with any term or requirement of any such
        Governmental Authorization, or (B) any actual, proposed,
        possible, or potential revocation, withdrawal, suspension,
        cancellation, termination of, or modification to any such
        Governmental Authorization; and (iv) the rights of the Sellers
        under such Governmental Authorizations shall not be affected by
        the consummation of the Contemplated Transactions.
        Notwithstanding anything herein to the contrary, the Sellers make
        no representation or warranty with respect to the applicability
        of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
        amended, to the Contemplated Transactions.

        commenced by or against any of the Sellers or that otherwise
        relates to or may affect the business of, or any of the assets
        owned or used by, any of the Sellers, or (ii) that challenges, or
        that may have the effect of preventing, delaying, making illegal,

        Transactions.  To the Knowledge of the Sellers, (A) no such
        Proceeding has been Threatened, and (B) no event has occurred or
        circumstance exists that may give rise to or serve as a basis for
        the commencement of any such Proceeding.

        Letter there is no Order to which any of the Sellers, or any of

        of the Sellers is in full compliance with all of the terms and
        requirements of each Order to which it, or any assets owned or
        used by it, is subject.

        than one percent of the outstanding capital stock of any
        Competing Business that is publicly traded on any recognized
        exchange or in the over-the-counter market.  Except as set forth
        in Part 3.18 of the Disclosure Letter, none of the Sellers nor

        4.   REPRESENTATIONS AND WARRANTIES OF BUYER

                  (b)  Except as set forth in Exhibit D, neither the
        execution and delivery of this Agreement by Buyer nor the
        consummation or performance of any of the Contemplated

        delay, or otherwise interfere with any of the Contemplated
        Transactions pursuant to:  (i) any provision of Buyer's
        Organizational Documents; (ii) any resolution adopted by the

             4.3  Certain Proceedings.  There is no pending Proceeding
        that has been commenced against Buyer and that challenges, or may
        have the effect of preventing, delaying, making illegal, or

        To Buyer's Knowledge, no such Proceeding has been Threatened.

             4.4  Brokers and Finders.  Buyer and its officers and agents
        have incurred no obligation or liability, contingent or
        otherwise, for brokerage or finders' fees or agents' commissions

        will indemnify and hold the Sellers and the Principals harmless
        from any such payment alleged to be due by or through Buyer as a
        result of the action of Buyer or its officers or agents.

        5.   INDEMNIFICATION; REMEDIES

             5.1  Survival.  Subject to Section 5.4, all representations,
        warranties, covenants, and obligations in this Agreement, the
        Disclosure Letter and any other certificate or document delivered
        pursuant to this Agreement will survive the Closing; the right to
        indemnification, reimbursement, or other remedy based on such
        representations, warranties, covenants, and obligations will not
        be affected by any investigation conducted with respect to, or
        any Knowledge acquired (or capable of being acquired) about the
        accuracy or inaccuracy of or compliance with, any such
        representation, warranty, covenant, or obligation.

             5.2  Indemnification and Reimbursement By the Sellers and
        the Principals.  The Sellers and the Principals will indemnify
        and hold harmless Buyer, its representatives, stockholders,
        controlling persons, and affiliates (collectively, the
        "Indemnified Persons"), and will reimburse the Indemnified
        Persons, for any loss, liability, claim, damage, expense
        (including costs of investigation and defense and reasonable
        attorneys' fees) or diminution of value, whether or not involving
        a third-party claim (collectively, "Damages"), arising from or in
        connection with:

                  (a)  any Breach of any representation or warranty made
        by any of the Sellers in this Agreement, the Disclosure Letter,
        or any other certificate or document delivered at and in
        connection with the Closing of the Contemplated Transactions by
        any of the Sellers pursuant to this Agreement;

                  (b)  any Breach by any of the Sellers of any covenant

                                       28PAGE
<PAGE>

                  (d)  any claim by any Person for brokerage or finder's
        fees or commissions or similar payments based upon any agreement
        or understanding alleged to have been made by any such Person
        with any of the Sellers or the Principals; or

                  (e)  any product liability claim relating to products
        sold by any of the Sellers prior to the Closing Date; provided
        that such claim is not caused by Buyer's intervening negligence
        in the service, maintenance or repair of such product.

             5.3  Indemnification and Reimbursement by Buyer.  Buyer will
        indemnify and hold harmless the Sellers and the Principals, and
        will reimburse the Sellers and the Principals, for any Damages
        arising from or in connection with (a) any Breach of any
        representation or warranty made by Buyer in this Agreement or in
        any certificate delivered by Buyer pursuant to this Agreement,
        (b) any Breach by Buyer of any covenant or obligation of Buyer in
        this Agreement, (c) any claim by any Person for brokerage or
        finder's fees or commissions or similar payments based upon any

        connection with any of the Contemplated Transactions or (d) any
        Assumed Liabilities.

             5.4  Time Limitations.  None of the Sellers or the
        Principals will have any liability for indemnification under
        section 5.2(a) with respect to any representation or warranty in
        Sections 3.4, 3.5, 3.7, 3.9, 3.12, 3.14, 3.16, 3.19, 3.20, 3.21,
        3.22, 3.23, 3.24 unless on or before March 31, 1997 the
        Representative is given notice of a claim specifying the factual
        basis of that claim in reasonable detail to the extent then known
        by Buyer.  None of the Sellers or the Principals will have any
        liability for indemnification under section 5.2(a) with respect
        to any representation or warranty in Sections 3.8, 3.10, 3.11,
        3.13, 3.15, 3.17, 3.18, 3.25, 3.26, unless on or before the
        second anniversary of the Closing Date the Representative is
        given notice of a claim specifying the factual basis of that
        claim in reasonable detail to the extent then known by Buyer.
        The Sellers and the Principals will have no liability for
        indemnification under Section 5.2(a) with respect to Section 3.1,
        3.2, 3.3, or 3.6, unless on or before the expiration of the
        applicable statute of limitations the Representative is given
        notice of a claim specifying the factual basis of that claim in
        reasonable detail to the extent known by Buyer.  A claim for
        indemnification or reimbursement under Sections 5.2 (b), (c) or
        (d) may be made at any time.  

             5.5  Limitations on Amount -- Sellers and Principals.

                  (a)  None of the Sellers or the Principals will have
        any liability for indemnification pursuant to Section 5.2(a), (i)
        at any time with respect to any claim by the Buyer for less than
        $5,000 and (ii) until the total of all Damages with respect to
                                       29PAGE
<PAGE>

        such matters (including claims under $5,000) exceeds $100,000,
        and then such liability shall only be for Damages in excess of
        $100,000.  Notwithstanding any provision herein to the contrary,
        except for liability for indemnification with respect to breaches
        of Sections 3.1, 3.2, 3.3 or 3.6, the maximum aggregate liability
        of the Sellers and the Principals under Section 5.2 shall not
        exceed $6,750,000.

                  (b)  Notwithstanding any provision herein to the
        contrary, except for liability for indemnification with respect
        to breaches of Sections 3.1, 3.2, 3.3 or 3.6, no Principal shall
        have any liability under section 5.2 in excess of the amount set
        forth opposite such Principal's name on Exhibit F attached
         hereto.  In addition, with respect to any single claim (and
        subject to the overall limitation set forth in the preceding
        sentence) for indemnification, Dennis Carlson shall not have any
        liability which is greater than the product of (i) the amount set
        forth opposite Dennis Carlson's name on Exhibit F attached hereto
        divided by $6,750,000 and (ii) the total amount of the claim for
        which Buyer is then seeking indemnification.  

             5.6  Procedures for Indemnification -- Third Party Claims.

                  (a)  Promptly after receipt by an indemnified party
        under Section 5.2 or  Section 5.3 of notice of the commencement
        of any Proceeding against it, such indemnified party will, if a
        claim is to be made against an indemnifying party under such
        Section, give notice to the indemnifying party of the
        commencement of such claim, but the failure to notify the
        indemnifying party will not relieve the indemnifying party of any
        liability that it may have to any indemnified party, except to
        the extent that the indemnifying party demonstrates that the
        defense of such action is prejudiced by the indemnifying party's
        failure to give such notice.

                  (b)  If any Proceeding referred to in Section 5.6(a) is
        brought against an indemnified party and it gives notice to the
        indemnifying party of the commencement of such Proceeding, the
        indemnifying party will, unless the claim involves Taxes, be
        entitled to participate in such Proceeding and, to the extent
        that it wishes (unless (i) the indemnifying party is also a party
        to such Proceeding and the indemnified party determines in good
        faith that joint representation would be inappropriate, or (ii)
        the indemnifying party fails to provide reasonable assurance to
        the indemnified party of its financial capacity to defend such
        Proceeding and provide indemnification with respect to such
        Proceeding), to assume the defense of such Proceeding with
        counsel satisfactory to the indemnified party and, after notice
        from the indemnifying party to the indemnified party of its
        election to assume the defense of such Proceeding, the
        indemnifying party will not, as long as it diligently conducts
        such defense, be liable to the indemnified party under this
        Section 5 for any fees of other counsel or any other expenses
        with respect to the defense of such Proceeding, in each case
                                       30PAGE
<PAGE>

        subsequently incurred by the indemnified party in connection with
        the defense of such Proceeding, other than reasonable costs of
        investigation.  If the indemnifying party assumes the defense of
        a Proceeding, (i) no compromise or settlement of such claims may
        be effected by the indemnifying party without the indemnified
        party's consent unless (A) there is no finding or admission of
        any violation of Legal Requirements or any violation of the
        rights of any Person and no effect on any other claims that may
        be made against the indemnified party, and (B) the sole relief
        provided is monetary damages that are paid in full by the
        indemnifying party; and (ii) the indemnifying party will have no
        liability with respect to any compromise or settlement of such
        claims effected without its consent.  If notice is given to an
        indemnifying party of the commencement of any Proceeding and the
        indemnifying party does not, within ten days after the
        indemnified party's notice is given, give notice to the
        indemnified party of its election to assume the defense of such
        Proceeding, the indemnifying party will be bound by any
        determination made in such Proceeding or any compromise or
        settlement effected by the indemnified party.  Notwithstanding
        the foregoing, if a customer or a supplier any of the Sellers
        asserts that the Buyer is liable to such customer or supplier for
        a monetary obligation which may constitute or result in Damages
        for which the Buyer may be entitled to indemnification pursuant
        to this Section 5 and the Buyer reasonably determines that it has
        a valid business reason to fulfill such obligations, then (i) the
        Buyer shall be entitled to satisfy such obligation without prior
        notice to or consent from the Sellers, (ii) the Buyer may make a
        claim for indemnification pursuant to this Section 5 and (iii)
        the Buyer shall be reimbursed, in accordance with the provisions
        of this Section 5, for any such Damages for which it is entitled
        to indemnification pursuant to the provisions of this Section 5;
        provided, however, that if the Buyer makes a claim for
        indemnification in accordance with this sentence the Sellers and
        the Principals shall not be deemed to have waived any defense to
        such claim by the Buyer, notwithstanding the Buyer's prior
        satisfaction of the obligation for which indemnification is
        sought, and it shall not be a defense to the Buyer's claim for
        indemnification that the Buyer has satisfied the obligation for
        which indemnification is sought.

                  (c)  Notwithstanding the foregoing, if an indemnified
        party determines in good faith that there is a reasonable
        probability that a Proceeding may adversely affect it or its
        affiliates other than as a result of monetary damages for which
        it would be entitled to indemnification under this Agreement, the
        indemnified party may, by notice to the indemnifying party,
        assume the exclusive right to defend, compromise, or settle such
        Proceeding, but the indemnifying party will not be bound by any
        determination of a Proceeding so defended or any compromise or
        settlement effected without its consent.

                  (d)  For purposes of providing any notice required
        under this Section 5, the Buyer may treat the Representative as
                                       31PAGE
<PAGE>

        the authorized representative of all of the Sellers and
        Principals any notice given to the Representative shall be deemed
        given to each Seller and each Principal.

             5.7  Procedure for Indemnification -- Other Claims.  A claim
        for indemnification for any matter not involving a third-party
        claim may be asserted by notice to the party from whom
        indemnification is sought.

        6.   GENERAL PROVISIONS

             6.1  Expenses.  Except as otherwise expressly provided in
        this Agreement, each party to this Agreement will bear its
        respective expenses incurred in connection with the preparation,
        execution, and performance of this Agreement and the Contemplated
        Transactions, including all fees and expenses of agents,
        representatives, counsel, and accountants.  In the event of
        termination of this Agreement, the obligation of each party to
        pay its own expenses will be subject to any rights of such party
        arising from a breach of this Agreement by another party.

             6.2  Public Announcements.  Any public announcement or
        similar publicity with respect to this Agreement or the

        only with the consent of the Representative, and by any of the
        Sellers or the Principals, only with the consent of the Buyer,

        will be subject to review and approval by the Buyer, none of

        will consult with each other concerning the means by which the
        Sellers' employees, customers, and suppliers and others having
        dealings with the Sellers will be informed of the Contemplated
        Transactions, and Buyer will have the right to be present for any
        such communication.

             6.4  Jurisdiction; Service of Process.  Any action or
        proceeding seeking to enforce any provision of, or based on any
        right arising out of, this Agreement may be brought against any
        of the parties in the courts of the Commonwealth of
        Massachusetts, County of Middlesex, or, if it has or can acquire
        jurisdiction, in the United States District Court for the
        District of Massachusetts and each of the parties consents to the
        jurisdiction of such courts (and of the appropriate appellate
        courts) in any such action or proceeding and waives any objection
        to venue laid therein.  With respect to MSC-UK and the
        Principals, any action or proceeding seeking to enforce any
        provision of, or based on any right arising out of, this
        Agreement may be brought against any of the parties in the courts
        of England and each of MSC-UK, the Principals and Buyer consents
        to the jurisdiction of such courts (and of the appropriate
        appellate courts) in any such action or proceeding and waives any
        objection to venue laid therein.  Process in any action or
        proceeding referred to in this Section 6.4 may be served on any
        party anywhere in the world.

             6.5  Further Assurances.  The parties agree (a) to furnish
        upon request to each other such further information, (b) to
        execute and deliver to each other such other documents, and (c)

             6.6  Waiver.  The rights and remedies of the parties to this
        Agreement are cumulative and not alternative.  Neither the
        failure nor any delay by any party in exercising any right,
        power, or privilege under this Agreement or the documents
        referred to in this Agreement will operate as a waiver of such
        right, power, or privilege, and no single or partial exercise of
        any such right, power, or privilege will preclude any other or
        further exercise of such right, power, or privilege or the
        exercise of any other right, power, or privilege.  To the maximum
        extent permitted by applicable law, (a) no claim or right arising
        out of this Agreement or the documents referred to in this
        Agreement can be discharged by one party, in whole or in part, by
        a waiver or renunciation of the claim or right unless in writing
        signed by the other party; (b) no waiver that may be given by a
        party will be applicable except in the specific instance for
        which it is given; and (c) no notice to or demand on one party
        will be deemed to be a waiver of any obligation of such party or
        of the right of the party giving such notice or demand to take
        further action without notice or demand as provided in this
        Agreement or the documents referred to in this Agreement.

             6.7  Entire Agreement and Modification.  This Agreement
        supersedes all prior agreements between the parties with respect
        to its subject matter and constitutes (along with the documents
        referred to in this Agreement) a complete and exclusive statement
        of the terms of the agreement between the parties with respect to
        its subject matter.  This Agreement may not be amended except by
        a written agreement executed by the party to be charged with the
        amendment.

             6.8  Disclosure Letter.  In the event of any inconsistency
        between the statements in the body of this Agreement and those in
        the Disclosure Letter (other than an exception expressly set
        forth as such in the Disclosure Letter with respect to a
        specifically identified representation or warranty), the
        statements in the body of this Agreement will control.

             6.9  Assignments, Successors, and Third-Party Rights.  No
        party hereto may assign any of its, his or her rights under this
        Agreement without the prior consent of the other parties except
        that Buyer may assign any of its rights under this Agreement to
        any Subsidiary of Buyer, provided that Buyer shall remain jointly
        and severally liable with such Subsidiary for any of Buyer's
        obligations hereunder.  Subject to the preceding sentence, this
        Agreement will apply to, be binding in all respects upon, and
        inure to the benefit of the successors and permitted assigns of
        the parties.  Nothing expressed or referred to in this Agreement
        will be construed to give any Person other than the parties to
        this Agreement any legal or equitable right, remedy, or claim
        under or with respect to this Agreement or any provision of this
        Agreement.  This Agreement and all of its provisions and
        conditions are for the sole and exclusive benefit of the parties
        to this Agreement and their successors and assigns.

             6.10 Severability.  If any provision of this Agreement is
        held invalid or unenforceable by any court of competent
        jurisdiction, the other provisions of this Agreement will remain
        in full force and effect.  Any provision of this Agreement held
        invalid or unenforceable only in part or degree will remain in
        full force and effect to the extent not held invalid or
        unenforceable.

             6.11 Section Headings; Construction.  The headings of
        Sections in this Agreement are provided for convenience only and
        will not affect its construction or interpretation.  All
        references to "Sections" refer to the corresponding Sections of
        this Agreement.  All words used in this Agreement will be
        construed to be of such gender or number as the circumstances
        require.  Unless otherwise expressly provided, the word
        "including" does not limit the preceding words or terms.

             6.12 Time of Essence.  With regard to all dates and time
        periods set forth or referred to  in this Agreement, time is of
        the essence.

        construed under the laws of the Commonwealth of Massachusetts
        without regard to conflicts of laws principles.

             6.14 Relief.  In the event of a breach of the provisions of
        this Agreement by a Seller, in addition to any other rights and
        remedies that Buyer may have under law or in equity, Buyer shall
        have the right to specific performance and injunctive relief, it
        being acknowledged and agreed that money damages will not provide
        an adequate remedy.

             6.15 Access to Information.  The Sellers shall make
        available, and direct and authorize their respective independent
        public accountants to make available, to the Buyer and to the
        independent public accountants representing the Buyer (at no cost
        to the Buyer), all working papers pertaining to the examination
        by the Sellers' accountants of the accounting records of the
        Sellers, and shall provide such cooperation as Buyer shall
        reasonably request in connection with Buyer's preparation of any
        financial statements relating to the businesses of the Sellers
        required to be included in any filing made by Buyer or any
        affiliate of Buyer with the Securities and Exchange Commission
        pursuant to the Securities Act or the Exchange Act.  For a period
        of time as may be reasonably requested, upon written request of a
        Seller or Principal, Buyer or its successor shall make or cause
        to be made available to such Seller or Principal, as the case may
        be, all books and records included in the Assets that are needed
        by such Seller or Principal for a valid business or financial
        purpose, and permit such Seller or Principal to inspect and copy
        such books and records upon reasonable notice and at such
        reasonable times as may be mutually agreed upon by such Seller or
        Principal and Buyer and shall be at such Seller's or Principal's
        sole cost and expense.

             6.16 Solicitation.  For a period of two years after the
        Closing Date, none of the Sellers or the Principals shall, either
        directly or indirectly as a stockholder, investor, partner,
        director, officer, employee or in any other capacity, solicit or
        attempt to induce any Restricted Employee to terminate his or her
        employment with Buyer or any affiliate of the Buyer;  provided,
        however, that it shall not be a breach of this Section 6.16 for
        any Seller or Principal to solicit Restricted Employees by means
        of general public advertisements.  For purposes of this
        agreement, a "Restricted Employee" shall mean any person, other
        than employees terminated involuntarily by the Buyer, who (i)
        either (A) hold or have access to trade secrets or other
        confidential information relating to the business of the Sellers
        or (B) had annual base salary in 1994 of at least $50,000, and
        (ii) either (X) was an employee of the Buyer or any affiliate of
        the Buyer on either the date of this Agreement or the Closing
        Date or (Y) was an employee of any of the Sellers on either the
        date of this Agreement or the Closing Date and who is employed by
        the Buyer immediately after the Closing.

             6.17 Non-Competition.

                  (a)  For a period of five years after the Closing Date,
        none of the Sellers or the Principals shall, either directly or
        indirectly as a stockholder, investor, partner, director,
        officer, employee, consultant or otherwise, engage in a
        Competitive Business in any territory.  For purposes of this
        Agreement, a "Competitive Business" means (i) the development,
        manufacture, marketing or sale of any product utilizing near
        infrared technology which is competitive with any product
        manufactured, sold or developed (or under development) by a
        Seller on or prior to the Closing Date or (ii) the rendering or
        marketing of any service which is competitive with any service
        rendered or marketed (or proposed to be rendered or marketed) by
        a Seller on or prior to the Closing Date.  Buyer acknowledges and
        agrees that the Principals are and will be passive investors in
        Sensortech Systems Inc.

                  (b)  The Sellers and the Principals agree that the
        duration and geographic scope of the non-competition provision
        set forth in this Section 6.17 are reasonable.  In the event that
        any court determines that the duration or the geographic scope,
        or both, are unreasonable and that such provision is to that
        extent unenforceable, the parties agree that the provision shall
        remain in full force and effect for the greatest time period and
        in the greatest area that would not render it unenforceable.  The
        parties intend that this non-competition provision shall be
        deemed to be a series of separate covenants, one for each and
        every county of each and every state of the U.S. and each and
        every political subdivision of each and every country outside the
        U.S. where this provision is intended to be effective.

             6.18 Seniority of Employees.  To the extent that length of
        service is relevant for vesting or benefit calculations or
        allowances under retirement or other benefit plans made available
        to Buyer's employees, any of the Seller's employees that accept
        employment with the Buyer shall receive credit for their years of
        service with the Sellers.

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

             6.20 Counterparts.  This Agreement may be executed in one or
        more counterparts, each of which will be deemed to be an original
        copy of this Agreement and all of which, when taken together,
        will be deemed to constitute one and the same agreement.

   Notes to Consolidated Financial Statements

   1.   Nature of Operations and Summary of Significant Accounting Policies

   Nature of Operations
   Thermedics Inc. (the Company) develops, manufactures, and markets precision
   weighing and inspection equipment, electrochemistry and microweighing
   products, product quality assurance systems, electronic test instruments
   and explosives-detection devices, as well as implantable heart-assist
   systems and other biomedical products. 

   Relationship with Thermo Electron Corporation
   The Company was incorporated in 1983 as a wholly owned subsidiary of Thermo
   Electron Corporation (Thermo Electron). As of December 30, 1995, Thermo
   Electron owned 17,315,326 shares of the Company's common stock,
   representing 51% of such stock outstanding (Note 15).

   Principles of Consolidation
   The accompanying financial statements include the accounts of the Company,
   its wholly owned subsidiaries, and its majority-owned public subsidiaries,
   Thermo Cardiosystems Inc. (Thermo Cardiosystems) and Thermo Voltek Corp.
   (Thermo Voltek). All material intercompany accounts and transactions have
   been eliminated. The Company's percentage ownership of its majority-owned
   public subsidiaries at year-end was as follows:

                                                       1995    1994    1993
                                                       ----    ----    ----

   Thermo Cardiosystems                                52%      55%    54%
   Thermo Voltek                                       50%      60%    53%

   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, $25,685,000 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. As of
   December 30, 1995, the Company's cash equivalents were also invested in
   U.S. government agency discount notes and money market preferred stock,
   which have an original maturity of three months or less. Cash equivalents
   are carried at cost, which approximates market value.

   Property, Plant and Equipment
   The costs of additions and improvements are capitalized, while maintenance
   and repairs are charged to expense as incurred. The Company provides for
   depreciation and amortization using the straight-line method over the
   estimated useful lives of the property as follows: buildings and
   improvements -- 5 to 25 years, machinery and equipment -- 3 to 10 years,

   Other Assets
   Other assets in the accompanying balance sheet includes the cost of
   acquired patents, trademarks, and other specifically identifiable
   intangible assets. These assets are being amortized using the straight-line
   method over their estimated useful lives, which range from 2 to 40 years.
   These assets were $2,916,000 and $3,037,000, net of accumulated
   amortization of $2,245,000 and $1,762,000, at year-end 1995 and 1994,
   respectively.

   Cost in Excess of Net Assets of Acquired Companies
   The excess of cost over the fair value of net assets of acquired companies
   is amortized using the straight-line method over periods not exceeding 40
   years. Accumulated amortization was $6,343,000 and $4,634,000 at year-end
   1995 and 1994, respectively. The Company assesses the future useful life of
   this asset whenever events or changes in circumstances indicate that the
   current useful life has diminished. The Company considers the future
   undiscounted cash flows of the acquired companies in assessing the
   recoverability of this asset.

   Foreign Currency
   All assets and liabilities of the Company's foreign subsidiaries are
   translated at year-end exchange rates, and revenues and expenses are
   translated at average exchange rates for the year in accordance with SFAS
   No. 52, "Foreign Currency Translation." Resulting translation adjustments
   are reflected as a separate component of shareholders' investment, titled
   "Cumulative translation adjustment." In 1994, the Company recorded foreign
   currency transaction gains of $635,000 on the repayment of intercompany
   borrowings, denominated in U.S. dollars, by several of the Company's
   foreign subsidiaries. The borrowings resulted from the acquisition of
   Ramsey Technology, Inc. by the Company. Foreign currency transaction gains
   are included in other income in the accompanying 1994 statement of income.
   There were no foreign currency transaction gains and losses in 1995, and
   the foreign currency transactions gains and losses included in the
   accompanying 1993 statement of income were immaterial. 

   Revenue Recognition
   In general, 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. Revenues and profits on substantially all contracts are
   recognized using the percentage-of-completion method. Revenues recorded
   under the percentage-of-completion method were $8,521,000 in 1995,
   $2,253,000 in 1994, and $5,087,000 in 1993. The percentage of completion is
   determined by relating either the actual costs or actual labor incurred to
   date to management's estimate of total costs or total labor, respectively,
   to be incurred on each contract. If a loss is indicated on any contract in
   process, a provision is made currently for the entire loss. The Company's
   contracts generally provide for billing of customers upon the attainment of
   certain milestones specified in each contract or for billing customers
   monthly as costs are incurred on a cost-plus-fixed-fee basis. Revenues
   earned on contracts in process in excess of billings are classified as
   unbilled contract costs and fees in the accompanying balance sheet. There
   are no significant amounts included in the accompanying balance sheet that
   are not expected to be recovered from existing contracts at current
   contract values, or that are not expected to be collected within one year,
   including amounts that are billed but not paid under retainage provisions.

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

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

        If gains have been recognized on issuances of a subsidiary's stock and
   shares of the subsidiary are subsequently repurchased by the subsidiary,
   the Company, or Thermo Electron, gain recognition does not occur on
   issuances subsequent to the date of a repurchase until such time as shares
   have been issued in an amount equivalent to the number of repurchased
   shares. Such transactions are reflected as equity transactions and the net
   effect of these transactions is reflected in the accompanying statement of
   shareholders' investment as "Effect of majority-owned subsidiaries' equity
   transactions."

   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 on the weighted average number
   of shares outstanding during the year. Because the effect of the assumed
   exercise of stock options would be immaterial, they have been excluded from
   the earnings per share calculation. Fully diluted earnings per share have
   not been presented because the effect of the assumed exercise of stock
   options and the assumed conversion of the Company's subordinated
   convertible debentures would be immaterial.

   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 liablilities 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.

        Short- and long-term available-for-sale investments in the
   accompanying 1995 balance sheet include $59,595,000 with contractual
   maturities of one year or less, $51,005,000 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 in 1995
   resulted from gross realized gains of $439,000 and gross realized losses of
   $18,000 relating to the sale of available-for-sale investments. Gain on
   sale of investments in 1994 resulted from gross realized gains of $241,000
   and gross realized losses of $38,000 relating to the sale of
   available-for-sale investments.

   3.   Acquisitions

   In December 1995, the Company acquired the Orion laboratory products
   division (Orion) of Analytical Technology, Inc. for approximately $52.7
   million in cash, which included the repayment of $8.6 million of debt,
   subject to a post-closing adjustment. To partially finance this
   acquisition, the Company borrowed $38.0 million from Thermo Electron
   pursuant to a promissory note due December 1996, and bearing interest at
   the Commercial Paper Composite Rate plus 25 basis points. The balance of
   the purchase price was funded from the Company's working capital. Orion
   manufactures electrochemistry, microweighing, process, and other
   instruments used to analyze the chemical composition of foods, beverages,
   and pharmaceuticals and detect contaminants in environmental and
   high-purity water samples. Additionally, in 1995, one of the Company's
   majority-owned subsidiaries made an acquisition for $3.8 million in cash.
        In March 1994, the Company acquired substantially all of the assets,
   subject to certain liabilities, of Ramsey Technology, Inc. (Ramsey), a
   business of Baker Hughes Incorporated, for a cash purchase price of $41.9
   million. In January 1996, Ramsey was contributed by the Company to its
   newly formed Thermo Sentron Inc. (Thermo Sentron) subsidiary in exchange
   for shares of Thermo Sentron common stock. Thermo Sentron designs,
   develops, manufactures, and sells high-speed precision weighing and
   inspection equipment for industrial production and packaging lines.
   Additionally, in 1994, the Company and one of its majority-owned
   subsidiaries made two other acquisitions for an aggregate of $2.8 million
   in cash.
        In August 1993, Thermo Voltek acquired Comtest Instrumentation B.V., a
   Netherlands-based company, and Comtest Limited, a U.K. operation
   (collectively, Comtest), for $831,000 in cash and the repayment of $238,000
   of Comtest's debt. Comtest distributes products used to test electronic
   equipment for electromagnetic compatibility (EMC), provides EMC-related
   consulting services, and manufactures specialized power supplies for
   telecommunications equipment. 
        These acquisitions have been accounted for using the purchase method
   of accounting, and their results of operations have been included in the
   accompanying financial statements from their respective dates of
   acquisition. The aggregate cost of the acquisitions in 1995, 1994, and
   1993, exceeded the estimated fair value of the acquired net assets by $86.4
   million, which is being amortized over periods not exceeding 40 years.
   Allocation of the purchase price for these acquisitions was based on
   estimates of the fair value of the net assets acquired and, for
   acquisitions completed in 1995, is subject to adjustment upon finalization
   of the purchase price allocation.
        Based on unaudited data, the following table presents selected
   financial information for the Company, Orion, Thermo Sentron, and Comtest
   on a pro forma basis, assuming the Company and Orion had been combined
   since the beginning of 1994 and the Company, Thermo Sentron and Comtest had
   been combined since the beginning of 1993. The effect on the Company's
   financial statements of the acquisitions not included in the pro forma data
   was not material to the Company's results of operations and financial
   position.

        The pro forma results are not necessarily indicative of future
   operations or the actual results that would have occurred had the
   acquisitions been made at the beginning of 1994 or 1993, as applicable.
        Other accrued expenses in the accompanying balance sheet include
   $2,454,000 and $3,080,000 at year-end 1995 and 1994, respectively, for
   estimated severance, relocation, and other reserves associated with
   acquisitions.


   4.   Stock-based Compensation Plans

   The Company has stock-based compensation plans for its key employees,
   directors, and others. Two of these plans, adopted in 1983, permitted the
   grant of nonqualified and incentive stock options. These plans expired
   during 1993. A third plan, adopted in 1993, permits the grant of a variety
   of stock and stock-based awards as determined by the human resources
   committee of the Company's Board of Directors (the Board Committee),
   including restricted stock, stock options, stock bonus shares, or
   performance-based shares. To date, only nonqualified stock options have
   been awarded under this plan. The option recipients and the terms of
   options granted under this plan are determined by the Board Committee.
   Generally, options granted to date are exercisable immediately, but are
   subject to certain transfer restrictions and the right of the Company to
   repurchase shares issued upon exercise of the options at the exercise
   price, upon certain events. The restrictions and repurchase rights
   generally lapse ratably over periods ranging from four to ten years after
   the first anniversary of the grant date, depending on the term of the
   option, which may range from seven to twelve years. Nonqualified stock
   options may be granted at any price determined by the Board Committee,
   although incentive stock options must be granted at not less than the fair
   market value of the Company's 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 stock-based
   compensation plans of Thermo Electron or its majority-owned subsidiaries.

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

   5.   Employee Benefit Plans

   Employee Stock Purchase Plan
   Substantially all of the Company's full-time U.S. employees are eligible to
   participate in an employee stock purchase plan sponsored by the Company or
   its majority-owned public subsidiaries. Prior to the November 1995 plan
   year, shares of the Company's or its majority-owned public subsidiaries',
   and shares of 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 14,552 shares, 13,711 shares, and 36,080 shares,
   respectively, of its common stock under this plan.

   The majority of the Company's full-time U.S. employees are eligible to
   participate in Thermo Electron's 401(k) savings plan and, prior to 1995, in
   Thermo Electron's employee stock ownership plan (ESOP). Contributions to
   the 401(k) savings plan are made by both the employee and the Company.
   Company contributions are based upon the level of employee contributions.
   For these plans, the Company contributed and charged to expense $1,011,000,
   $942,000, and $412,000 in 1995, 1994, and 1993, respectively. Effective
   December 31, 1994, the ESOP was split into two plans: ESOP I, covering
   employees of Thermo Electron's corporate office and its wholly owned
   subsidiaries and ESOP II, covering employees of certain of Thermo
   Electron's majority-owned subsidiaries, including the Company. Also,
   effective December 31, 1994, the ESOP II plan was terminated and as a
   result, the Company's employees are no longer eligible to participate in an
   ESOP.

   6.  Income Taxes (continued)

        The valuation allowance relates primarily to the uncertainty
   surrounding the realizability of net operating loss and credit
   carryforwards, and other tax assets of certain subsidiaries. The decrease
   in the valuation allowance is due primarily to reduced uncertainty
   surrounding the realizability of such future tax benefits and was recorded
   in part as a reduction of the 1995 provision for income taxes and as an
   increase to capital in excess of par value. 
        As of December 30, 1995, federal and state tax attributes existed at
   Thermo Voltek, which are not consolidated for federal tax purposes. Thermo
   Voltek had federal and state tax net operating loss carryforwards of
   approximately $3,000,000 expiring in 1998 through 2006 and general business
   credits of approximately $132,000 expiring in 1996 through 2004. These tax
   assets and the related valuation allowance are included above. The
   carryforwards of Thermo Voltek are limited to a tax benefit of
   approximately $240,000 per year under Sections 382 and 383 of the U.S.
   Internal Revenue Code. 
        The Company has not recognized a deferred tax liability for the
   difference between the book basis and tax basis of the common stock of its
   domestic subsidiaries (such difference relates primarily to unremitted
   earnings and gains on issuance of stock by subsidiaries) because the
   Company does not expect this basis difference to become subject to tax at
   the parent level. The Company believes it can implement certain tax
   strategies to recover its investment in its domestic subsidiaries tax-free.
        A provision has not been made for U.S. or additional foreign taxes on
   $3,371,000 of undistributed earnings of foreign subsidiaries that could be
   subject to taxation if remitted to the U.S. because the Company currently
   plans to keep these amounts permanently reinvested overseas. The Company
   believes that any additional U.S. tax liability due upon remittance of such
   earnings would be immaterial due to available U.S. foreign tax credits.


   7.   Commitments

   The Company leases various office and manufacturing facilities under
   noncancellable operating lease arrangements expiring between 1996 and 2003.
   The accompanying statement of income includes expenses from operating
   leases of $3,403,000, $2,081,000, and $882,000 in 1995, 1994, and 1993,
   respectively. Future minimum payments due under noncancellable operating
   leases as of December 30, 1995, are $3,291,000 in 1996; $2,326,000 in 1997;
   $1,959,000 in 1998; $1,341,000 in 1999; $731,000 in 2000; and $419,000 in
   2001 and thereafter. Total future minimum lease payments are $10,067,000.

                                                           $45,201   $82,551
                                                           =======   =======

        The Company's convertible obligations are guaranteed on a subordinated
   basis by Thermo Electron. The Company has agreed to reimburse Thermo
   Electron in the event Thermo Electron is required to make a payment under
   its guarantee of Thermo Voltek's or Thermo Cardiosystems' obligations. 
        In lieu of issuing shares of Thermo Voltek common stock upon the
   conversion of the 3 3/4% subordinated convertible debentures due 2000,
   Thermo Voltek has the option to pay holders of the debentures cash equal to
   the weighted average market price of Thermo Voltek's common stock on the
   trading date prior to conversion.
        During 1995, 1994, and 1993, convertible obligations of $37,317,000,
   9,745,000, and 9,190,000, respectively, were converted into common stock of
   the Company.
        See Note 13 for the fair value of the Company's long-term obligations.
        The Company borrowed $38,000,000 from Thermo Electron pursuant to a
   promissory note due December 1996, to partially finance the acquisition of
   Orion in December 1995 (Note 3).
        Several of the Company's foreign subsidiaries have lines of credit
   under which an aggregate of approximately $13,800,000 may be borrowed at a
   current rate as determined by each country's local market. The lines of
   credit are denominated in local currency. Amounts borrowed under these
   agreements are included in notes payable and current maturities of
   long-term obligations in the accompanying balance sheet and are guaranteed
   by either the Company or Thermo Electron. The weighted average interest
   rate on these borrowings was 8.5% and 7.7% at year-end 1995 and 1994,
   respectively.


   9.   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
                                       22PAGE

   Notes to Consolidated Financial Statements

   9.   Related Party Transactions (continued)

   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 relationships among Thermo Electron and its
   majority-owned subsidiaries). In addition, the Company utilizes data
   processing and contract administration services of two majority-owned
   subsidiaries of Thermo Electron, which are charged based on actual usage.
   For these services, as well as the administrative services provided by
   Thermo Electron, the Company was charged $2,142,000, $1,964,000, and
   $1,086,000 in 1995, 1994, and 1993, respectively. Management believes that
   the service fees charged by Thermo Electron and its subsidiaries 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.

   Distribution Agreements
   Pursuant to international distributorship agreements, the Company appointed
   Arabian Business Machines Co. (ABM) and Olayan Financing Company (OFC) as
   its exclusive distributors of the Company's security instruments in certain
   Middle Eastern countries. ABM and OFC are members of The Olayan Group. Ms.
   Hutham S. Olayan, a Director of Thermo Electron, is the President and a
   Director of Olayan America Corporation and Competrol Real Estate Limited,
   two other members of The Olayan Group, which are indirectly controlled by
   Suliman S. Olayan, Ms. Olayan's father. Revenues recorded under this
   agreement totaled $3,000, $42,000, and $33,000 in 1995, 1994, and 1993,
   respectively. In addition, during 1994 the Company sold $1,240,000 of
   security instruments directly to a customer in the Middle East and paid a
   commission of $409,000 pursuant to the ABM distributor agreement.

   Management Contract
   Prior to 1994, the Company performed supervisory management services with
   respect to International Technidyne Corporation (ITC), a wholly owned
   subsidiary of Thermo Electron, in exchange for a fixed fee of $150,000 per
   year, plus an incentive fee based on objective financial performance
   criteria established on an annual basis by Thermo Electron and the Company.
   Effective January 2, 1994, in lieu of the management fee, two executive
   employees of the Company allocate a portion of their salary and bonus for
   the time they devote to Thermo Electron in connection with certain
   management responsibilities relating to ITC and Thermo Electron's other
   biomedical businesses. In 1995, 1994, and 1993, the Company was reimbursed
   $402,000, $84,000, and $266,000, respectively, under these arrangements.

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

   9.   Related Party Transactions (continued)

   Short-term Available-for-sale Investments
   At December 30, 1995, the Company's short-term available-for-sale
   investments included $2,052,000 of 6 1/2% subordinated convertible
   debentures due 1997, which were purchased on the open market for
   $1,795,000. The debentures have a par value of $1,800,000 and were issued
   by Thermo TerraTech Inc., a majority-owned subsidiary of Thermo Electron.


   10. Contingency

   Thermo Cardiosystems has received correspondence alleging that the textured
   surface of its left ventricular-assist system's 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 Thermo Cardiosystems were sued on these
   bases, it would have meritorious defenses. 


   11. Common Stock

   At December 30, 1995, the Company had reserved 2,977,154 unissued shares of
   its common stock for possible issuance under stock-based compensation plans
   and possible issuance upon conversion of the 6 1/2% subordinated
   convertible debentures (Note 15).
        During 1994, the Company issued 66,265 shares of its common stock to
   Thermo Electron in exchange for 124,800 shares of Thermo Voltek common
   stock.


   12. Transactions in Stock of Subsidiaries

   During 1995, $9,111,000 principal amount of Thermo Voltek's subordinated
   convertible debentures were converted into 775,399 shares of Thermo Voltek
   common stock, resulting in gains of $3,455,000 from the issuance of stock
   by subsidiary. 
        During 1995, $21,808,000 principal amount of Thermo Cardiosystems'
   subordinated convertible obligations were converted into 1,027,984 shares
   of Thermo Cardiosystems common stock. No gains were recorded on the
   conversions of these convertible obligations as Thermo Cardiosystems was
   principally engaged in research and development at the time the convertible
   obligations were issued.

   13.  Fair Value of Financial Instruments

   The Company's financial instruments consist mainly of cash and cash
   equivalents, available-for-sale investments, accounts receivable, notes
   payable and current maturities of long-term obligations, accounts payable,
   due to parent company, and long-term obligations. The carrying amounts of
   these financial instruments, with the exception of available-for-sale
   investments and long-term obligations, approximates fair value due to their
   short-term nature.
        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 long-term obligations was determined based on quoted
   market prices. The fair value of convertible obligations at year-end 1995
   exceeds the carrying amount primarily due to the market price of the
   Company's or subsidiaries' common stock exceeding the conversion price of
   the convertible obligations. The carrying amount and fair value of the
   Company's long-term obligations are as follows:

                                  1995                         1994

   14.  Business Segments, Geographical Information and 
        Concentrations of Risk

   The Company's principal businesses can be divided into two segments. The
   Company's Instruments and Other Equipment segment develops, manufactures,
   sells, and distributes precision equipment that weighs and inspects bulk
   materials and packaged goods; electrochemistry, microweighing, and other
   laboratory instruments; process detection instruments; explosives-detection
   instruments; instruments that test electronic and electrical systems and 
   components for immunity to electromagnetic interference; high-voltage
   power-conversion systems; and provides related consulting services. The
   Company's Biomedical Products segment develops, manufactures, and sells
   left ventricular-assist systems (LVAS) and other biomedical products.
        The Company's Instruments and Other Equipment segment derived revenues
   from precision weighing and inspection equipment of $67.5 million and $50.1
   million in 1995 and 1994, respectively. In addition, this segment derived
   revenues from process detection instruments of $16.2 million, $38.0
   million, and $34.4 million and from electronic test instruments of $31.6
   million, $19.0 million, and $13.2 million in 1995, 1994, and 1993,
   respectively.
        The Company's Biomedical Products segment derived revenues from LVAS
   devices of $20.6 million, $10.4 million, and $3.5 million in 1995, 1994,
   and 1993, respectively.
        Certain raw materials used in the manufacture of Thermo Cardiosystems'
   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.
        No customer represented 10% or more of the Company's total revenues in
   1995. During 1994 and 1993, revenues derived from one customer represented
   21% and 43% of the Company's total revenues, respectively.

   Report Of Independent Public Accountants

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

   We have audited the accompanying consolidated balance sheets of Thermedics
   Inc. (a Massachusetts corporation and 51%-owned subsidiary of Thermo
   Electron Corporation) and subsidiaries as of December 30, 1995 and December
   31, 1994, and the related consolidated statements of income, shareholders'
   investment, and cash flows for each of the three years in the period ended
   December 30, 1995. These consolidated financial statements are the
   responsibility of the Company's management. Our responsibility is to
   express an opinion on these consolidated financial statements based on our
   audits.
        We conducted our audits in accordance with generally accepted auditing
   standards. Those standards require that we plan and perform the audit to
   obtain reasonable assurance about whether the financial statements are free
   of material misstatement. An audit includes examining, on a test basis,
   evidence supporting the amounts and disclosures in the financial
   statements. An audit also includes assessing the accounting principles used
   and significant estimates made by management, as well as evaluating the
   overall financial statement presentation. We believe that our audits
   provide a reasonable basis for our opinion.
        In our opinion, the consolidated financial statements referred to
   above present fairly, in all material respects, the financial position of
   Thermedics Inc. and subsidiaries as of December 30, 1995 and December 31,
   1994 and the results of their operations and their 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 consolidated 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's business can be divided into two segments: Instruments and
   Other Equipment, and Biomedical Products. The Instruments and Other
   Equipment segment includes Ramsey Technology, Inc., which was acquired in
   March 1994 and was contributed by the Company in January 1996 to its newly
   formed Thermo Sentron Inc. (Thermo Sentron) subsidiary in exchange for
   shares of Thermo Sentron common stock. Thermo Sentron designs, develops,
   manufactures, and sells high-speed precision weighing and inspection
   equipment for industrial production and packaging lines. The Instruments
   and Other Equipment segment also includes the Orion laboratory products
   division (Orion) of Analytical Technology, Inc., which was acquired in
   December 1995. Orion is a manufacturer of electrochemistry, microweighing,
   process, and other instruments used to analyze the chemical compositions of
   foods, beverages, and pharmaceuticals and detect contaminants in
   environmental and high-purity water samples. The Instruments and Other
   Equipment segment, through the Company's Thermedics Detection Inc.
   (Thermedics Detection) subsidiary, also develops, manufactures, and markets
   high-speed detection instruments, including the Alexus(R) system, a process
   detection instrument used in product quality assurance applications, and
   the EGIS(R) system, a security instrument used to detect explosives at
   airports and other locations. Through the Company's Thermo Voltek Corp.
   (Thermo Voltek) subsidiary, the Instruments and Other Equipment segment
   also manufactures a line of electronic test instruments and high-voltage
   power conversion systems.
        As part of its Biomedical Products segment, the Company's Thermo
   Cardiosystems Inc. (Thermo Cardiosystems) subsidiary has developed two
   implantable left ventricular-assist systems (LVAS): a pneumatic, or
   air-driven system, and an electric version. In October 1994, the Company
   announced that the U.S. Food and Drug Administration (FDA) 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. Thermo
   Cardiosystems 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. Thermo
   Cardiosystems' electric LVAS is being used in Europe as a
   bridge-to-transplant and as an alternative to heart transplant. According
   to terms set by the FDA, no profit can be earned from the sale of an LVAS
   until the FDA has approved the device for commercial sale. With FDA
   approval, the Company began earning a profit on the sale of its air-driven
   LVAS in the fourth quarter of 1994. In October 1994, Thermo Cardiosystems
   announced a price increase in the U.S. for its air-driven LVAS that was
   phased in during a six-month period that more than doubled the average
   price of the air-driven LVAS. The Company also develops and manufactures
   enteral nutrition delivery systems and a line of medical-grade polymers,

   Overview (continued)

   competitive position can be affected by currency exchange rate fluctuations
   affecting the relationship between the U.S. dollar and foreign currencies.
   Where appropriate, the Company uses forward contracts to reduce its
   exposure to currency fluctuations.
        In October 1995, the Financial Accounting Standards Board (FASB)
   issued an exposure draft of a Proposed Statement of Financial Accounting
   Standards, "Consolidated Financial Statements:  Policy and Procedures"
   (Proposed Statement). The Proposed Statement would establish new rules for
   how consolidated financial statements should be prepared. If the Proposed
   Statement is adopted, there could be significant changes in the way the
   Company records certain transactions of its controlled subsidiaries,
   including the following: (i) any sale of the stock of a subsidiary that
   does not result in a loss of control would be accounted for as a
   transaction in equity of the consolidated entity with no gain or loss being
   recorded and (ii) under certain circumstances acquisitions could be
   structured to significantly reduce the goodwill that is recorded and
   consequently reduce the Company's future goodwill amortization associated
   with the acquisition. The Company typically acquires technology companies
   which are often characterized by significant amounts of goodwill. In
   addition, under the Proposed Statement, a company that has made certain
   equity investments of generally less than 20% ownership would record a gain
   (or loss) upon increasing its investment level to the point of exerting
   "significant influence," generally 20% or higher.
        The FASB conducted a hearing concerning the Proposed Statement in
   February 1996, at which Thermo Electron, along with other major companies
   and many of the major accounting firms and accounting associations,
   expressed their disagreement with various parts of the Proposed Statement.
   The FASB expects to issue a final Statement by June 30, 1996, which could
   become effective for fiscal years beginning after December 15, 1996.

   Results of Operations

   1995 Compared With 1994

   Total revenues in 1995 were $175.8 million, compared with $155.1 million in
   1994. Instruments and Other Equipment segment revenues increased 10% to
   $136.7 million in 1995 from $124.1 million in 1994. Revenues increased
   $17.4 million due to the inclusion of sales for a full year from Thermo
   Sentron, which was acquired in March 1994. Revenues from Thermo Voltek
   increased $12.7 million, due to the inclusion of an additional $7.2 million
   in revenues from businesses acquired in 1994 and 1995, an increase of $3.1
   million in revenues from Comtest due primarily to the introduction of a new
   product line in 1995, and an increase of $2.3 million in revenues from
   Keytek due to greater demand. Revenues at Thermedics Detection were $28.0
   million in 1995, compared with $50.3 million in 1994. Revenues from
   Thermedics Detection's process detection instruments declined to $16.2
   million in 1995 from $38.0 million in 1994. This decline is due to a
   decrease in demand from Thermedics Detection's principal customer, which
   has substantially completed its deployment of Alexus product quality
   assurance systems. While the Company has expanded its customer base and
   continues to develop Alexus upgrades and new applications for its process
   detection technology in the food and beverage market, no assurance can be

   given that the Company will be able to significantly broaden the market for
   its process detection systems.
        Revenues from Thermedics Detection's EGIS explosives-detection system
   declined to $8.0 million in 1995 from $10.1 million in 1994. The Company's
   sales of the EGIS system have been made primarily to government entities
   outside of the U.S. During 1993 and 1994, large orders from the U.K. and
   German governments accounted for a significant portion of EGIS sales. These
   orders have now been filled. Demand for this highly specialized product
   will vary widely over time in a particular country, and among different
   countries, due to many factors beyond the control of the Company, such as
   budgetary constraints and social and political concerns about security. Due
   to the nature of demand for the EGIS system, future sales levels will
   depend, to a significant extent, upon the Company's ability to obtain large
   orders from one or more government entities.
        Biomedical Products segment revenues increased 26% to $39.0 million in
   1995 from $31.0 million in 1994. Revenues from Thermo Cardiosystems
   increased by $10.2 million to $20.6 million due in part to an increase in
   the price of the LVAS. 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 increase in revenues from Thermo Cardiosystems was partially
   offset by a decline of $2.8 million in revenues from Scent Seal fragrance
   samplers. In June 1995, the Company entered into an agreement granting an
   exclusive license to all of its patents and know-how relating to the Scent
   Seal fragrance samplers to a third party in consideration for royalty
   payments on future sales by the licensee. The Company recorded royalty
   income of $197,000 in 1995.
        The gross profit margin was 45% in 1995, compared with 44% in 1994.
   The gross profit margin for the Instruments and Other Equipment segment was
   43% in 1995, compared with 44% in 1994. This decline was due primarily to
   lower gross margins at Thermedics Detection as a result of a lower sales
   volume and, to a lesser extent, the inclusion of lower-margin research and
   development contract revenues. In addition, Thermo Voltek's gross profit
   margin decreased to 48% in 1995 from 49% in 1994 due primarily to higher
   European sales in one product line, which has lower margins due to
   competitive pricing pressures. These decreases were offset in part by
   improved gross profit margins at Thermo Sentron due to a reduction in
   operating expenses. The gross profit margin for the Biomedical Products
   segment was 49% in 1995, compared with 42% in 1994, reflecting higher
   margins at Thermo Cardiosystems resulting from the LVAS price increase and,
   to a lesser extent, the increase in sales volume and improvements in
   manufacturing efficiencies. 
        Selling, general and administrative expenses as a percentage of
   revenues decreased to 27% in 1995 from 28% in 1994. This decline results
   primarily from lower expenses as a percentage of revenues at Thermo
   Cardiosystems as a result of a higher sales volume in 1995 and, to a lesser
   extent, a reduction in operating expenses at Thermo Sentron. These
   improvements were partially offset by higher expenses as a percentage of
   revenues at Thermedics Detection due to a lower sales volume in 1995.
   Research and development expenses as a percentage of revenues decreased to
   6.3% in 1995 from 6.7% in 1994 due primarily to lower expenses as a
   percentage of revenues at Thermo Cardiosystems as a result of an increase
   in total revenues.

   1995 Compared With 1994 (continued)

        Interest income increased to $9.1 million in 1995 from $7.3 million in
   1994 due to higher prevailing interest rates in 1995. Interest expense
   increased to $3.7 million in 1995 from $3.2 million in 1994 as a result of
   borrowings by Thermo Sentron's and Thermo Voltek's foreign subsidiaries,
   offset in part by a decrease in interest expense due to conversions of
   subordinated convertible obligations.
        Gain on issuance of stock by subsidiary of $3.5 million in 1995
   resulted from the conversion of $9.1 million principal amount of Thermo
   Voltek's 3 3/4% subordinated convertible debentures.
        The effective tax rate was 32% in 1995, compared with 38% in 1994. The
   effective tax rate in 1995 was below the statutory federal income tax rate
   due primarily to the nontaxable gain on issuance of stock by subsidiary and
   the reduction of the valuation allowance no longer required, offset in part
   by state income taxes (Note 6). The effective tax rate in 1994 was higher
   than the statutory federal income tax rate due primarily to state income
   taxes.
        Minority interest expense increased to $4.5 million in 1995 from $1.2
   million in 1994 due to higher net income at the Company's 52%-owned Thermo
   Cardiosystems subsidiary and, to a lesser extent, the Company's 50%-owned
   Thermo Voltek subsidiary.

   1994 Compared With 1993

   Total revenues in 1994 were $155.1 million, compared with $80.2 million in
   1993, an increase of 93%. Instruments and Other Equipment segment revenues
   more than doubled in 1994 to $124.1 million from $60.1 million in 1993.
   This increase reflects the inclusion of $50.1 million in revenues from
   Thermo Sentron, which was acquired in March 1994, $4.6 million in
   additional revenues from Comtest, which was acquired by Thermo Voltek in
   August 1993, and an increase of $4.1 million in revenues from the Company's
   EGIS explosives-detection systems. Process detection instrument sales,
   principally to one customer, were $38.0 million in 1994, compared with
   $34.4 million in 1993. 
        Biomedical Products segment revenues increased 54% to $31.0 million in
   1994 from $20.1 million in 1993. The improvement is primarily the result of
   a $6.9 million increase in sales of Thermo Cardiosystems' LVAS to $10.4
   million and additional revenues of $3.0 million from Scent Seal fragrance
   samplers, which were introduced in the first quarter of 1993.
        The Company's gross profit margin remained relatively unchanged at 44%
   in 1994 and 43% in 1993. The gross profit margin for the Instruments and
   Other Equipment segment remained unchanged at 44% in both 1994 and 1993.
   Improved efficiencies in the worldwide service organization for process
   detection instruments and, to a lesser extent, improved margins at  
   Universal Voltronics as a result of increased commercial sales relative to
   lower-margin government contract revenues were offset by the inclusion of
   lower-margin Thermo Sentron revenues. The gross profit margin for the
   Biomedical Products segment was 42% in 1994, compared with 38% in 1993,
   reflecting higher margins derived from Thermo Cardiosystems' LVAS due to
   higher sales, manufacturing efficiencies, and the initial impact of the
   price increase for the air-driven system which took effect in the fourth
   quarter of 1994.
        Operating income, before the inclusion of Thermo Cardiosystems'
   results, was $15.3 million in 1994, compared with $10.2 million in 1993.

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

   1994 Compared With 1993 (continued)

   This improvement results primarily from higher sales, which resulted in
   higher gross profit. Including Thermo Cardiosystems' operating losses of
   $0.9 million in 1994 and $3.2 million in 1993, the Company reported
   operating income of $14.3 million in 1994, compared with $7.1 million in
   1993. Thermo Cardiosystems' lower operating loss resulted primarily from an
   increased gross profit margin on higher revenues, partially offset by
   increased expenses to develop and market its LVAS. 
        Interest income increased to $7.3 million in 1994 from $6.1 million in
   1993. This increase is due to higher average invested amounts derived from
   the issuance of $34.5 million principal amount of 3 3/4% subordinated
   convertible debentures by Thermo Voltek in November 1993, and the issuance
   of $33.0 million principal amount of noninterest-bearing subordinated
   convertible debentures by Thermo Cardiosystems in January 1994. This
   increase was offset in part by cash expended for the acquisition of Thermo
   Sentron in March 1994. Interest expense increased to $3.2 million in 1994
   from $2.4 million in 1993 due to the issuance of the 3 3/4% subordinated
   convertible debentures by Thermo Voltek, partially offset by conversions of
   the Company's 6 1/2% subordinated convertible debentures.
        Other income includes $635,000 in 1994 relating to foreign currency
   transaction gains.
        The effective tax rate was 38% in 1994 and 40% in 1993. These rates
   exceed the statutory federal income tax rate due primarily to state income
   taxes (Note 6). 

   Liquidity and Capital Resources

   Working capital, including cash, cash equivalents, and short-term
   available-for-sale investments, was $110.1 million at December 30, 1995,
   compared with $128.3 million at December 31, 1994. Cash, cash equivalents,
   and short- and long-term available-for-sale investments were $155.2 million
   at December 30, 1995, compared with $154.1 million at December 31, 1994. Of
   the $155.2 million balance at December 30, 1995, $90.5 million was held by
   Thermo Cardiosystems, $34.7 million by Thermo Voltek, and the remainder by
   the Company and its wholly owned subsidiaries. During 1995, $14.9 million
   of cash was provided by operating activities and the Company expended $4.4
   million on purchases of property, plant and equipment. 
        In December 1995, the Company acquired Orion for approximately $52.7
   million in cash, which included the repayment of $8.6 million of debt,
   subject to a post-closing adjustment. To partially finance this
   acquisition, the Company borrowed $38.0 million from Thermo Electron
   pursuant to a promissory note due December 1996, and bearing interest at
   the Commercial Paper Composite Rate plus 25 basis points. The balance of
   the purchase price was funded from the Company's working capital. In
   January 1996, the Company acquired the assets of Moisture Systems
   Corporation, based in Hopkinton, Massachusetts, and certain affiliated
   companies, as well as Netherlands-based Rutter & Co., for a total purchase
   price of $20.5 million in cash and the assumption of certain liabilities.
   In connection with these acquisitions, the Company borrowed $15.0 million
   from Thermo Electron pursuant to a promissory note due February 1997, and
   bearing interest at the Commercial Paper Composite Rate plus 25 basis
   points. Thermo Electron has indicated its intention to require the
   Company's indebtedness to Thermo Electron be repaid to the extent the
   Company's liquidity and cash flow permit. On February 1, 1996, Thermo

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

   Liquidity and Capital Resources (continued)

   Sentron filed a registration statement under the Securities Act of 1933
   with the Securities and Exchange Commission covering shares of common stock
   to be offered in its initial public offering.
        The Company intends, for the foreseeable future, to maintain at least
   50% ownership of Thermo Cardiosystems, Thermo Voltek and Thermo Sentron.
   This may require the purchase by the Company of additional shares of common
   stock or, if applicable, convertible debentures (which are then converted)
   of these companies from time to time, if the number of the companies'
   outstanding shares increases, whether as a result of conversion of
   convertible notes or exercise of stock options issued by them, or
   otherwise. These or any other purchases may be made either in the open
   market or directly from Thermo Cardiosystems, Thermo Voltek or Thermo
   Sentron, or pursuant to the conversion of all or part of Thermo Voltek's
   subordinated convertible notes held by Thermedics. During 1995, the Company
   expended $179,000 to purchase shares of Thermo Voltek common stock on the
   open market.
        In 1996, the Company expects to make capital expenditures of
   approximately $6.6 million. The Company expects to continue to pursue its
   strategy of expanding its business both through the continued development,
   manufacture, and sale of new products, and through the possible acquisition
   of companies that will provide additional marketing or manufacturing
   capabilities and new products. The Company expects that it will finance
   these acquisitions through a combination of internal funds, additional debt
   or equity financing from the capital markets, or short-term borrowings from
   Thermo Electron. The Company believes its existing resources are sufficient
   to meet the capital requirements of its existing operations for the
   foreseeable future.
