  Item 1. Business

   (a) General Development of Business.

       Thermo TerraTech Inc. (the Company or the Registrant, formerly
  Thermo Process Systems Inc.) is a provider of environmental services and
  infrastructure planning and design services, encompassing a range of
  specializations within the consulting and design, remediation and
  recycling, and laboratory-testing industries. The Company also provides
  metal-treating services and thermal-processing systems used to treat
  primary metals and metal parts.

       The Company offers engineering, consulting, and design services in
  the areas of municipal and industrial water quality management; bridge
  and highway construction and reconstruction; and natural resource
  management. While each of its consulting and design subsidiaries
  separately offers its services to public- and private-sector clients,
  they are also able to combine their strengths to provide clients with
  joint solutions to their engineering, consulting, and design problems.

       The Company is a leading national provider of contaminated
  soil-remediation services and a leading regional supplier of fluids-
  remediation services. The Company also provides consulting and
  environmental management services, and is a major supplier of nuclear-
  remediation and safety services at radioactively contaminated sites. The
  Company's majority-owned, publicly held Thermo Remediation Inc. (Thermo
  Remediation) subsidiary, a national leader in the design and operation of
  nonhazardous soil-remediation facilities, operates a network of such
  facilities serving customers in more than a dozen states along the East
  and West Coasts. In December 1995, Thermo Remediation acquired
  Remediation Technologies, Inc. (ReTec), a provider of consulting,
  engineering, and on-site services to help clients manage problems
  associated with environmental compliance, waste management, and the
  remediation of industrial sites contaminated with organic wastes and
  residues. The purchase price for ReTec of $29.7 million consisted of
  $18.5 million in cash, shares of Thermo Remediation common stock and
  warrants valued at $3.7 million, and approximately $7.5 million
  attributable to the conversion of outstanding ReTec stock options into
  Thermo Remediation stock options of equivalent intrinsic value at the
  date of the acquisition. Thermo Remediation's Thermo Nutech division also
  provides services to remove radioactive contaminants from sand, gravel,
  and soil, as well as health physics services, radiochemistry laboratory,
  and dosimetry services. Thermo Remediation's Thermo Fluids subsidiary
  collects, tests, processes, and recycles used motor oil and other
  industrial oils. As of March 30, 1996, the Company owned 65.9% of Thermo
  Remediation's common stock and holds a $2,650,000 principal amount 3 7/8%
  subordinated convertible note due 2000 issued by Thermo Remediation,
  convertible into shares of Thermo Remediation common stock at a
  conversion price of $9.83 per share.

       The Company's majority-owned Thermo EuroTech N.V. (formerly
  Beheersmaatschappij J. Amerika N.V.) subsidiary is a provider of
  fluids-recycling and other environmental services in the Netherlands. As
  of March 30, 1996, the Company owned 62% of the outstanding common stock
  of Thermo EuroTech.
                                        2PAGE
<PAGE>
       The Company's Thermo Analytical subsidiary operates a network of
  analytical laboratories that provide comprehensive laboratory-based
  environmental testing, analysis, and related services to detect and
  measure organic contaminants in samples of soil, water, air, industrial
  wastes, mixed wastes, and biological materials. In May 1995, the Company
  acquired substantially all of the assets of Lancaster Laboratories, Inc.
  and its affiliate Clewmark Holdings (collectively Lancaster Laboratories)
  for $25.3 million in cash, which included the repayment of $5.3 million
  of debt. Lancaster Laboratories, based in Lancaster, Pennsylvania, is a
  provider of high-quality analytical services to the environmental, food,
  and pharmaceutical industries.

       The Company performs metallurgical processing services using
  thermal-treatment equipment at locations in California and Minnesota. The
  Company also designs, manufactures, and installs computer-controlled,
  custom-engineered, thermal-processing systems used to treat primary metal
  and metal parts.

       Effective April 2, 1995, the Company and Thermo Instrument Systems
  Inc. (Thermo Instrument) agreed to dissolve their environmental services
  joint venture (the joint venture). The Company purchased the businesses
  formerly operated by the joint venture from Thermo Instrument for $34.3
  million in cash. To finance this transaction, the Company issued to
  Thermo Electron Corporation (Thermo Electron) a $35.0 million promissory
  note that bears interest at the 90-day Commercial Paper Composite Rate
  plus 25 basis points, set at the beginning of each quarter, and is due
  May 13, 1997. In June 1995, the Company transferred three businesses
  formerly operated by the joint venture, collectively known as Thermo
  Nutech, to Thermo Remediation in exchange for 1,583,360 shares of Thermo
  Remediation common stock.

       The Company was incorporated on May 30, 1986, as an indirect, wholly
  owned subsidiary of Thermo Electron. Prior to its incorporation, the
  Company's operations were conducted by two wholly owned subsidiaries of
  Thermo Electron. As of March 30, 1996, Thermo Electron owned 14,501,958
  shares of the common stock of the Company, representing 83% of such stock
  then outstanding. Thermo Electron is a world leader in environmental
  monitoring and analysis instruments and a manufacturer of biomedical
  products including heart-assist systems and mammography systems;
  papermaking and recycling equipment; alternative-energy systems;
  industrial process equipment; and other specialized products. Thermo
  Electron also conducts advanced technology research and development.

       Thermo Electron has announced that it may repurchase shares of the
  Company's common stock from time to time in the open market or in
  negotiated transactions. During fiscal 19961, Thermo Electron purchased
  576,700 shares of the Company's common stock in the open market for a
  total price of $7,419,000.

  (b)  Financial Information About Industry Segments.

       The Company conducts business in one segment, environmental
  services. Within this segment, the principal products and services are:
  consulting and design, remediation and recycling services and 
  laboratory-based testing. The Company also provides specialized 
  metal-treating services including the design, manufacture, and 
  installation of advanced custom-engineered thermal-processing systems.

  (c)  Description of Business.

       (i) Principal Services and Products

  Consulting and Design Services

       The Company provides a wide range of environmental consulting
  services to private- and public-sector clients. These services include
  the design and inspection of water supply and wastewater treatment
  facilities; investigations of different methods to clean up hazardous
  waste sites; assistance in obtaining government permits;
  transportation-related and similar types of infrastructure engineering,
  survey, and land-use planning; and support services which include
  mechanical, electrical, and structural engineering. In addition, the
  Company provides natural resource management services including
  environmental impact studies.

       The Company is a leading provider of comprehensive environmental
  consulting and professional engineering services in selected areas of the
  United States. Through the February 1995 acquisition of Elson T. Killam
  Associates (Killam Associates), the Company is a leader in the design,
  planning, and construction supervision of municipal and privately owned
  water treatment plants, waste treatment plants, and hazardous wastewater
  facilities. The Company specializes in full-service contract operations
  to plant owners in the public and private sectors. These services
  facilitate regulatory compliance; optimize day-to-day plant operations;
  reduce costs; provide competent, experienced personnel; and promote good
  community relations.

       The Company provides a broad range of bridge and highway engineering
  services through its Bettigole Andrews & Clark subsidiary.

       The Company's Normandeau Associates subsidiary's environmental
  impact assessments and mitigation/restoration studies help determine
  water quality, promote the safety of wildlife, and assist clients in
  meeting environmental permitting and licensing requirements. Normandeau
  Associates is a leading provider of aquatic biology expertise and
  ecological risk assessment to electric utility plants throughout the
  country.

       The market for the Company's environmental analysis and field
  services consists primarily of customers who need to comply with federal,
  state, and local regulations that relate to environmental protection, the
  management and treatment of hazardous wastes, and the need to upgrade and
  expand infrastructure in response to economic development. These
  customers typically rely on independent laboratories and environmental
  science and engineering consultants, such as the Company's, for ongoing
  analysis and monitoring of such wastes and direction for compliance with
  various environmental regulations.
                                        4PAGE
<PAGE>
       A substantial portion of the Company's consulting and design
  services sales are made to existing customers on a repeat basis.
  Consulting and design services are often performed as multi-year studies.
  In addition to federal, state, and local governments, customers include
  public utilities, consulting and construction engineers, waste management
  companies, oil refineries, mining companies, chemical manufacturers,
  architectural and engineering firms, and a variety of service companies
  involved with real estate transactions.

       During fiscal 1996, 1995, and 1994, the Company derived revenues of
  $74.0 million, $40.3 million, and $29.7 million, respectively, from
  consulting and design services.

  Remediation and Recycling Services

       The Company is a leading national provider of contaminated
  soil-remediation services and a leading regional supplier of
  fluids-remediation services. The Company also provides consulting and
  environmental management services, and is a major supplier of nuclear
  remediation and safety services at radioactively contaminated sites.

       The Company's Thermo Remediation subsidiary, a national leader in
  the design and operation of nonhazardous soil-remediation facilities,
  operates a network of such facilities serving customers in more than a
  dozen states along the East and West coasts. Headquartered in Florida,
  Thermo Remediation operates fully permitted, environmentally secure
  soil-remediation centers in California, Florida, Maryland, New York,
  Oregon, South Carolina, Virginia, and Washington. Thermo Remediation
  thermally treats soil to remove and destroy hydrocarbon contamination
  caused by leaking underground storage tanks, aboveground storage tanks,
  spills accumulated at manufactured-gas plants and refineries, and other
  sources. The Company's strategy is to compete by providing its customers
  with protection from environmental liabilities under federal, state, and
  local law and superior service at competitive prices. Customers,
  particularly large national accounts, choose Thermo Remediation's
  services rather than those of other remediation companies and landfills
  because of Thermo Remediation's stringent pre-screening and documentation
  procedures, state-of-the-art facilities, thorough processing technology,
  post-treatment certification, and affiliation with Thermo Electron.
  Accordingly, the majority of Thermo Remediation's revenues are derived
  from larger liability-conscious companies, including the major oil
  companies and their affiliated service stations, public utilities, large
  industrial companies, and car rental companies, as well as the federal
  government, the military, and certain municipal governments and agencies.

       The Company and Thermo Electron entered into a development agreement
  under which Thermo Electron funded $4.0 million of the direct and
  indirect costs of the Company's development of soil-remediation centers.
  In exchange for this funding, the Company granted Thermo Electron a
  royalty equal to approximately 3% of net revenues from soil-remediation
  services performed at the centers developed under the agreement. The
  Company recorded contract revenues of $776,000 under the agreement for
  development costs expended in fiscal 1994. As of October 2, 1993, funding
  under the agreement was complete. The Company paid royalties of $332,000,
  $432,000, and $351,000 in fiscal 1996, 1995, and, 1994, respectively, to
  Thermo Electron.
                                        5PAGE
<PAGE>
       In December 1995, Thermo Remediation acquired ReTec, a provider of
  consulting, engineering, and on-site services to help clients manage
  problems associated with environmental compliance, waste management, and
  the remediation of industrial sites contaminated with organic wastes and
  residues. ReTec provides particular expertise in managing wastes from
  manufactured-gas plants, refineries, and railroad properties. As a leader
  in the application of bioremediation technologies, with 17 offices
  located in 16 states, ReTec was the first firm to successfully employ
  bioremediation as the principal technology to clean up a Superfund site.
  In addition, ReTec offers a broad array of remedial solutions, all of
  which are applied from a risk management perspective. ReTec concentrates
  on providing its clients with low-cost and innovative solutions to
  complex problems. For example, ReTec has led successful brownfield
  redevelopment projects that have helped transform contaminated properties
  into productive assets.

       Thermo Remediation's Thermo Nutech division also provides services
  to remove radioactive contaminants from sand, gravel, and soil, as well
  as health physics services, radiochemistry laboratory, and dosimetry
  services. Over the past 30 years, Thermo Nutech's health physics group
  has conducted hundreds of radiological surveys of soil contaminated with
  low levels of radioactivity. To reduce the high cost of cleanup and
  disposal, Thermo Nutech is developing a range of automated, technology-
  based services for radioactive soil remediation, some of which are based
  on proprietary technologies. For example, the Company's segmented-gate
  system automatically assays and separates radioactively contaminated soil
  from uncontaminated soil. This technology has been used to remediate more
  than 100,000 tons of plutonium-contaminiated soil on Johnston Atoll under
  an ongoing contract with the Nuclear Defense Agency, as well as to
  process soils at the DOE's Savannah River site. Thermo Nutech also
  provides health physics and industrial hygiene services in support of
  environmental investigation and remediation projects, including site
  surveys for radioactive materials and on-site sampling and analysis in
  support of radiological decontamination programs, and operates
  radiochemistry laboratories that provide a range of analytical laboratory
  services to the nuclear utility and environmental industries. The
  Company's Thermo Nutech division has been negatively affected by reduced
  federal spending on remediation of nuclear sites.

       The Company, through its Thermo Fluids subsidiary, collects, tests,
  processes, and recycles used motor oil and other industrial oils. In
  addition, the Company collects and recycles oily water and oil filters.
  Thermo Fluids has collection facilities located in Phoenix and Tucson,
  Arizona, and Las Vegas, Nevada. From these sites, Thermo Fluids operates
  a fleet of oil and water collection trucks to pick up waste oils and oily
  water.

       The Company's majority-owned Thermo EuroTech subsidiary, located in
  the Netherlands, provides wastewater treatment services as well as
  services to test, remove, and install underground storage tanks. In March
  1995, Thermo EuroTech acquired Refining and Trading B.V. Conducting
  business under the name "North Refinery," the Company specializes in
  processing "off-spec" mixtures of oil that contain water, ash, and
  sediment into commercially tradable end products used in blending.
  Although a large percentage of North Refinery's oil feedstock has
  historically come from the former Soviet Union, the volume of oil
  received from that nation has dropped significantly as a result of
  political and economic changes that make transportation of waste oil
                                        6PAGE
<PAGE>
  difficult. To overcome this loss of supply, North Refinery has taken
  steps to diversify its feedstock suppliers. However, no assurance can be
  given that it will not experience future disruptions in deliveries. The
  recent grant of a chemical-waste permit for the processing of a special
  classification of oil-contaminated liquids has also allowed North
  Refinery to begin processing chemical-waste streams. The end products of
  this process are commercial grade oils that can be blended to make diesel
  fuels and marine fuels or be used as a feed material. The Company's
  strategy is to use Thermo EuroTech as a platform from which to eventually
  provide a broad range of environmental remediation services throughout
  Western Europe.

       During fiscal 1996, 1995, and 1994, the Company derived revenues, of
  $77.0 million, $58.2 million, and $48.7 million, respectively, from its
  remediation and recycling services.

  Laboratory-testing Services

       Through a network of facilities in the United States, the Company
  provides comprehensive laboratory-based services for the environmental,
  pharmaceutical, and food industries. These laboratories also provide
  analysis and related services to detect and measure hazardous wastes and
  radioactive materials. Each of the laboratories in the Company's network
  has developed specializations, and samples obtained by one laboratory can
  be shipped to the specialists in the network for analysis, enabling the
  network to provide a full complement of analytical and testing services.

       Analytical laboratory services consist of a comprehensive range of
  analytical tests to detect and measure organic contaminants, inorganic
  contaminants, and radioactive materials in samples of soil, water, air,
  industrial wastes, and biological materials. The Company has established
  detailed procedures and strict operating standards to ensure consistent
  performance and to allow it to participate in the Environmental
  Protection Agency's (EPA's) Contract Laboratory Program (CLP). The EPA,
  through the CLP, solicits bids on a competitive basis from commercial
  laboratories to perform testing and analysis. The Company's environmental
  laboratory business has been negatively affected by reduced federal
  spending on environmental testing.

       Through the May 1995 acquisition of Lancaster Laboratories, the
  Company is a high-quality provider of analytical services to the
  environmental, food, and pharmaceutical industries. The Company believes
  that Lancaster Laboratories is the largest single-site commercial
  analytical laboratory in the country. Due to its size and national
  reputation for quality, Lancaster Laboratories has benefited from the
  growing trend of pharmaceutical and food manufactures to outsource their
  analytical laboratory functions to single-source providers.

       During fiscal 1996, 1995, and 1994, the Company derived revenues of
  $34.6 million, $8.6 million, and $6.0 million, respectively, from its
  laboratory-testing services.


                                        7PAGE
<PAGE>
  Metal-treating Services and Process Systems

       The Company performs metallurgical processing services using
  thermal-treatment equipment at locations in California and Minnesota.
  Through its equipment division located in Michigan, the Company also
  designs, manufactures, and installs computer-controlled, custom-
  engineered, thermal-processing systems used to treat primary metals and
  metal parts.

       During fiscal 1996, 1995, and 1994, the Company derived revenues of
  $31.8 million, $26.7 million, and $25.7 million, respectively, from its
  metal-treating services.

       (ii) New Products

       The Company has made no commitments to new products that would
  require the investment of a material amount of the Company's assets.

       (iii) Raw Materials

       A large percentage of North Refinery's oil feedstock has
  historically come from the former Soviet Union. The volume of oil
  received from that nation has dropped significantly as a result of
  political and economic changes that make transportation of waste oil
  difficult. To overcome this loss of supply, North Refinery has taken
  steps to diversify its feedstock suppliers. However, no assurance can be
  given that it will not experience future disruptions in deliveries.

       The principal materials used by the Company in its manufacturing
  operations are fabricated steel, alloy castings, and ceramic and
  insulating refractory materials. To date, the Company has not experienced
  any difficulty in obtaining any of the materials or components used in
  its operations and does not foresee any such difficulty in the future.
  The Company has multiple sources for all of its significant raw material
  needs.

       (iv) Patents, Licenses, and Trademarks

       The Company currently owns or has rights under licenses to a number
  of U.S. patents. Although the Company believes that patent protection
  provides it with competitive advantages with respect to certain portions
  of its business and will continue to seek patent protection when
  appropriate, the Company also believes that its business depends
  primarily upon trade secrets and the technical and marketing expertise of
  its personnel.

       (v) Seasonal Influences

       While the Company conducts significant operations year-round, the
  majority of its businesses experience seasonal fluctuations due to
  adverse weather during winter months. Such seasonal influences may have a
  material effect on the Company's revenues. The Company experienced
  significant adverse weather during the fourth quarter of fiscal 1996.
                                        8PAGE
<PAGE>
       (vi) Working Capital Requirements

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

       (vii) Dependency on a Single Customer

       The Company derived 10%, 6%, and 16% of its total revenues in fiscal
  1996, 1995, and 1994, respectively, from contracts or subcontracts with
  the federal government.

       (viii) Backlog

       The Company's backlog of firm orders was $95,419,000 and $70,589,000
  as of March 30, 1996 and April 1, 1995, respectively. These amounts
  include the backlog of the Company's ReTec subsidiary and backlog from
  consulting and design services, laboratory testing services, and process-
  systems products. Soil-recycling and metallurgical services are provided
  on a current basis pursuant to purchase orders. Accordingly, there is no
  backlog for these services. The process-systems backlog includes the
  incomplete portion of equipment contracts that are accounted for using
  the percentage-of-completion method. Of the fiscal 1996 backlog amount,
  substantially all orders are expected to be filled within the current
  fiscal year.

       (ix) Government Contracts

       Approximately 10%, 6%, and 16% of the Company's revenues in fiscal
  1996, 1995, and 1994, respectively, were derived from contracts or
  subcontracts with the federal government that are subject to
  renegotiation of profits or termination. The Company does not have any
  knowledge of threatened or pending renegotiation or termination of any
  material contract or subcontract.

       (x) Competition

  Consulting and Design Services

       The Company's consulting and design businesses are engaged in highly
  competitive markets in all of its service areas. These markets tend to be
  regional. In its geographic service area, competition consists of small
  one- to three-person firms offering a limited scope of services, as well
  as much larger firms that may be regional, national, or international in
  the scope of services they offer. The principal competitive factors for
  the Company are: reputation; experience; breadth and quality of services
  offered; and technical, managerial, and business proficiency.

  Remediation and Recycling Services

       The Company's competition for soil-remediation services is primarily
  from other fixed-site thermal treatment facilities and from landfills.
  The Company is aware of two other companies that operate fixed-site,
  thermal-treatment facilities for soil remediation in multiple states.
  However, several large waste management companies are analyzing this
  market and may compete with the Company in the future. The market for
  petroleum-contaminated, soil-processing services is highly fragmented and
  limited to geographic area within several hundred miles of a site. The
                                        9PAGE
<PAGE>
  Company also competes with operators of mobile thermal-treatment
  facilities, bioremediation and vapor-extraction technologies and, in
  certain states, with asphalt plants and brick kilns that use the
  contaminated soil in their production processes. The Company competes
  primarily based on its ability to offer its customers superior protection
  from environmental liabilities. Many of the Company's largest customers,
  such as the major oil companies, are extremely sensitive to environmental
  liability and therefore conduct thorough environmental audits of
  soil-treatment facilities before qualifying them as approved facilities.
  These approvals constitute an important barrier to entry into this
  segment of the soil-remediation market. Although the Company typically
  prices its services at a premium over landfills and other treatment
  technologies, competitive conditions limit the prices charged by the
  Company in each local market. Pricing is therefore a major competitive
  factor for the Company.

       Each of ReTec's offices is engaged in highly competitive, regional
  markets. ReTec's competition consists of numerous small firms offering
  limited services, as well as much larger firms that offer an array of
  services. The principal competitive factors for ReTec are: reputation;
  experience; breadth and quality of services offered; and technical,
  managerial and business proficiency.

       Thermo Nutech faces competition from many large national
  competitors, and competes primarily on the basis of its proprietary
  technology and price.

       Thermo Fluids operates the largest fleet of collection vehicles in
  Arizona and Nevada. Thermo Fluids competes with numerous smaller and
  several larger national companies in its current markets.

       Thermo EuroTech faces competition for oil from other oil processors
  and blenders and from a company with a similar distillation technology in
  Italy. The market for blending oils is very large and oils such as Thermo
  EuroTech's end products represent a very small percentage of the total
  market.

  Laboratory-testing Services

       Hundreds of independent analytical testing laboratories and
  consulting firms compete for environmental services business nationwide.
  Many of these firms use equipment and processes similar to those of the
  Company. Competition is based not only on price, but also on reputation
  for accuracy, quality, and the ability to respond rapidly to customer
  requirements. In addition, many industrial companies have their own
  in-house analytical testing capabilities. The Company believes that its
  competitive strength lies in the quality and expertise of its services.

  Metal-treating Services and Process Systems

       The market for metal-treating services is typically regional and
  very competitive. Both regions in which the Company has facilities
  contain numerous competitors. In addition, in-house heat-treating
  facilities provide a major source of competition. The Company competes in
  this segment on the basis of services provided, turnaround time, and
  price.
                                       10PAGE
<PAGE>
       The market for thermal-processing systems is subject to intense
  competition worldwide. The Company is aware of at least eight companies
  that market a number of products comparable to the Company's, but
  competition for particular projects is typically limited to fewer
  companies. The Company competes on the basis of several factors,
  including technical performance, product quality and reliability, timely
  delivery, and often price. Certain products sold by the Company's
  competitors are less expensive than comparable products sold by the
  Company.

       (xi) Environmental Protection Regulations

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

       (xii) Number of Employees

       At March 30, 1996, the Company employed 2,367 persons.

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

       The Company's exports by domestic operations and foreign operations
  are currently insignificant.

  (e)  Executive Officers of the Registrant.

  Company (an international manufacturer of specialized machine tools), a
  subsidiary of Cross and Trecker. Mr. Herkert has served as President of
  the Company's Killam Associates subsidiary since 1977. Messrs.
  Hatsopoulos and Kelleher are full-time employees of Thermo Electron, but
  devote such time to the affairs of the Company as the Company's needs
  reasonably require.


  Item 2. Properties

       The location and general character of the Company's principal
  properties as of March 30, 1996, are as follows:

       The Company owns approximately 324,000 square feet of office,
  engineering, laboratory, production, and manufacturing space, principally
  in Massachusetts, Minnesota, New Jersey, New Mexico, California, and
  Pennsylvania, and leases approximately 805,000 square feet of office,
  engineering, laboratory, production, and manufacturing space, pursuant to
  leases expiring in fiscal 1997 through 2008, principally in California,
  Michigan, Massachusetts, Connecticut, South Carolina, Florida, Texas,
  Montana, North Carolina, Colorado, Louisiana, Washington, Minnesota,
  Indiana, Kansas, Ohio, Tennessee, New Jersey, New Mexico, New York,
  Pennsylvania, New Hampshire, Maine, and Vermont.

       The Company also owns approximately 96 acres primarily in
  California, Florida, Oregon, South Carolina, and Maryland, from which it
  provides soil-remediation services. The Company occupies approximately 22
  acres principally in South Carolina, Virginia, Washington, California,
  and New York, pursuant to leases expiring in fiscal 1998 through 2005,
  from which it provides soil-remediation services.

       The Company occupies approximately eight acres on two sites in
  Arizona and one site in Nevada, pursuant to leases expiring in fiscal
  1997 and 1998, consisting of office space, fluids-recycling and
  maintenance facilities, and sites from fluids storage tanks.

       The Company occupies approximately 15 acres in Delfzijl, Holland,
  pursuant to leases expiring in 1998 through 2059, consisting of office
  space, distillation facilities, and oil storage tanks.

       The Company believes that these facilities are in good condition and
  are adequate for its present operations and that other suitable space is
  readily available if any of such leases are not extended.

  Item 3. Legal Proceedings

       In February 1996, the Company settled its previously disclosed
  litigation with Recycling Sciences International, Inc. on terms that were
  not material to the Company's results of operations or financial
  condition.

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

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

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

       We have audited in accordance with generally accepted auditing
  standards, the consolidated financial statements included in Thermo
  TerraTech Inc.'s Annual Report to Shareholders incorporated by reference
  in this Form 10-K, and have issued our report thereon dated May 7, 1996
  (except with respect to the matters discussed in Note 16 as to which the
  date is May 8, 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 16 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

  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.

             FISCAL AGENCY AGREEMENT, dated as of May 2, 1996 (this
        "Agreement"), among THERMO TERRATECH INC., a corporation duly
        organized and validly existing under the laws of the State of
        Delaware (the "Company"), THERMO ELECTRON CORPORATION, a
        corporation duly organized and validly existing under the laws of
        the State of Delaware (the "Guarantor"), and CHEMICAL BANK, a
        banking corporation duly organized and validly existing under the
        laws of the State of New York (the "Fiscal Agent").

             1.   The Securities.

                  (a)  The Company has, by a Subscription Agreement,
        dated April 26, 1996 (the "Subscription Agreement"), among the
        Company, the Guarantor and the managers named therein (the
        "Managers"), agreed to issue and sell to the Managers U.S.
        $100,000,000 aggregate principal amount of its 4-5/8% Convertible
        Subordinated Debentures Due 2003 (hereinafter referred to as the
        "Initial Securities" and together with the Over-Allotment
        Securities (as defined below), if any, the "Securities").  In
        addition, the Company has granted an option to the Managers to
        subscribe for up to an additional U.S. $15,000,000 principal
        amount of Securities (the "Over-Allotment Securities") solely to
        cover over-allotments, if any.  The amount of Securities that may
        be issued hereunder may be increased by agreement among Lehman
        Brothers International (Europe) (the "Lead Manager"), the
        Company, the Guarantor and the Fiscal Agent, and such additional
        securities shall be "Securities" hereunder.  The due and punctual
        payment of principal, premium, if any, and interest and
        Additional Amounts (as defined in Section 2 of the Securities) on
        the Securities when and as the same shall become due and payable,
        whether at maturity, upon redemption or otherwise, are
        unconditionally guaranteed on a subordinated basis by the
        Guarantor.  Interest on the Securities shall be calculated on the
        basis of a 360 day year comprised of twelve 30-day months.

                  (b)  Pursuant to the Subscription Agreement, the
        Managers (or their affiliates) may sell the Securities to (i)
        persons who are not "U.S. Persons" (as such term is defined in
        Regulation S promulgated by the United States Securities and
        Exchange Commission (the "SEC") pursuant to the Securities Act of
        1933, as amended (the "Securities Act")) in transactions that
        meet the requirements of Regulation S, (ii) "qualified
        institutional buyers" (as such term is defined in Rule 144A
        promulgated by the SEC pursuant to the Securities Act and
        hereinafter referred to as "QIBs") in reliance on Rule 144A (the
        Securities that are resold by the Managers pursuant to Rule 144A
        being hereinafter referred to as the "Rule 144A Securities") and
        (iii) a limited number of "institutional accredited investors"
        (within the meaning of Rule 501(a)(1), (2), (3) or (7)
        promulgated by the SEC pursuant to the Securities Act)
        ("Institutional Accredited Investors") that, prior to their
        purchase of any Securities, deliver to the Managers a letter
        containing certain representations and agreements.

                  (c)  A portion of the Securities will initially be
        issued in the form of a temporary global debenture in bearer form
        without coupons or conversion rights having endorsed thereon the
        guarantee of the Guarantor (the "Guarantee"), which will be
        deposited with a depository in London for Cedel and Euroclear for
        the accounts of the subscribers of such Securities on the Closing
        Date (as defined herein).  Upon deposit of the temporary global
        debenture, Cedel or Euroclear, as the case may be, will credit
        each subscriber with a principal amount of Securities equal to
        the principal amount thereof for which it has subscribed and paid
        in the aggregate principal amount of the entire issue of
        Securities less the aggregate principal amount of the Rule 144A
        Securities and Accredited Investor Securities concurrently
        issued, substantially in the form of Exhibit B hereto (the
        "Regulation S Global Security").  As hereinafter provided, the
        Regulation S Global Security may subsequently be exchanged for
        Securities (i) in printed definitive form with the Guarantees
        endorsed thereon either as (a) bearer Securities ("Bearer
        Securities") in denominations of U.S. $1,000 and U.S. $10,000 and
        with interest coupons attached thereto, representing the
        semi-annual interest payable thereon, or (b) fully registered
        Securities ("Registered Regulation S Securities") in
        denominations of U.S. $1,000 and integral multiples thereof,
        without coupons, or (ii) a beneficial interest in the Rule 144A
        Global Security (as defined below), in accordance with the
        provisions of Section 3(c).  Bearer Securities shall be
        substantially in the form of Exhibit A hereto, including the
        coupons set forth therein.  Registered Regulation S Securities
        also shall be substantially in the form of Exhibit A hereto.  The
        Securities which are not Bearer Securities or the Regulation S
        Global Security are hereinafter collectively referred to as the
        "Registered Securities."

                  (d)  The Rule 144A Securities will initially be issued
        in the form of a global Security in the aggregate principal
        amount of the Rule 144A Securities, which Security shall be in
        substantially the form of Exhibit A hereto, having endorsed
        thereon a Guarantee, and is hereinafter referred to as the "Rule
        144A Global Security." Such Rule 144A Global Security shall be
        duly executed by the Company and authenticated by the Fiscal
        Agent (as defined below) as hereinafter provided and will be
        deposited on the Closing Date with, or on behalf of, The
        Depositary Trust Company ("DTC") and registered in the name of
        Cede & Co., as nominee of DTC.  The aggregate principal amount of
        the Rule 144A Global Security may from time to time be increased
        or reduced by adjustments made in the Security Register.
        Transfers of interests in the Rule 144A Global Security will be
        subject to certain restrictions set forth therein and described
        in Section 3 hereof.

                  (e)  The Accredited Investor Securities will initially
        be issued in fully registered form in minimum denominations of
        U.S. $250,000 and integral multiples of U.S. $1,000 in excess
        thereof, which Securities shall be in substantially the form of
                                        2PAGE
<PAGE>
        Exhibit A hereto, having endorsed thereon a Guarantee, and are
        hereinafter collectively referred to as "Registered Accredited
        Investor Securities." Such Registered Accredited Investor
        Securities shall be in definitive, fully registered certificated
        form only and registered in the names of such Institutional
        Accredited Investors or their nominees.  Such Institutional
        Accredited Investors may not elect to hold Registered Accredited
        Investor Securities through DTC, Euroclear or Cedel.  The
        aggregate principal amount of the Registered Accredited Investor
        Securities may be increased or reduced by adjustments made in the
        Security Register.  Transfers of Registered Accredited Investor
        Securities will be subject to certain restrictions set forth
        therein and described in Section 3 hereof.

                  (f)  During the period beginning on the Closing Date
        and ending on the date which is three years (or the then
        applicable holding period under Rule 144(k) under the Securities
        Act (or successor provision)) after the later of the date of
        original issuance thereof and the last date on which the Company
        or any affiliate of the Company was the owner thereof (or any
        predecessor), all Rule 144A Securities, all Accredited Investor
        Securities, all other Registered Securities and all Securities
        issued upon registration of transfer of or in exchange for such
        Securities, shall be "Restricted Securities" and shall be subject
        to the restrictions on transfer in Section 3 hereof; provided,
        however, that the term "Restricted Securities" shall not include
         Registered Securities as to which such restrictions on transfer
        have been terminated in accordance with Section 3(g) hereof.  All
        Restricted Securities shall bear the legend required by Section
        3(f) hereof.

                  (g)  The Securities will be convertible as provided in
        Section 4 of the Registered Securities and the Bearer Securities
        and Section 7 hereof.  The Securities may be redeemed by the
        Company as provided in Section 3 of the Registered Securities and
        the Bearer Securities and Section 6 hereof.  The Securities will
        be subordinated as provided in Section 7 of the Registered
        Securities and the Bearer Securities.  The Registered Securities,
        the Bearer Securities and the Regulation S Global Security shall
        contain such appropriate insertions, omissions, substitutions and
        other variations as are required or permitted by this Agreement
        and may have such letters, numbers or other marks of
        identification and such legends or endorsements placed thereon as
        may, consistent herewith, be determined by the officer of the
        Company executing such Securities, as evidenced by his execution
        of such Securities.

                  (h)  The Company in issuing the Securities shall use
        CUSIP numbers, and the Fiscal Agent may use such CUSIP numbers in
        any notice of redemption with respect to the Securities.  The
        Company shall obtain one CUSIP number for the Rule 144A
        Securities and one for the Registered Regulation S Securities.
        In addition, the Company shall obtain an ISIN number and a Common
                                        3PAGE

        and the Registered Regulation S Securities.

                  (i)  Pursuant to the Subscription Agreement, the
        Managers (or their affiliates) may sell the Securities to persons

        who is within the United States or to a United States person
        other than (a) foreign branches of United States financial
        institutions if such institutions agree in writing to comply with
        the requirements of Section 165(j)(3)(A), (B), or (C) of the

        thereunder, (b) United States offices of exempt distributors, or
        (c) United States offices of international organizations or
        foreign central banks.  United States tax laws and regulations
        also require that Bearer Securities not be delivered within the
        United States or its possessions.

                  (j)  The Company will use its reasonable best efforts
        to have the Securities approved for listing on the Luxembourg
        Stock Exchange or such other exchange as shall be agreed upon by
        the Managers and the Company, as soon as practicable after the
        date hereof.

             3.   Registration of Transfer and Exchange; Restrictions on
        Transfer.

                  (a)  Upon surrender for registration of transfer of any
        Registered Security at any office or agency designated for such
        purpose by the Company pursuant to Section 12(g) hereof, the
        Company shall execute, and the Fiscal Agent shall authenticate,

        amount, having endorsed thereon a Guarantee duly executed by the
        Guarantor, and bearing such restrictive legends as may be

        to any Registered Security that is a Restricted Security, the
        Fiscal Agent shall not register the transfer of such Security
        unless the conditions in Sections 3(b) hereof shall have been
        satisfied.  The holder of each Restricted Security, by such
        holder's acceptance thereof, agrees to be bound by the transfer
        restrictions set forth herein and in the legend on such
        Restricted Security.

                  (b)  Whenever any Restricted Security is presented or
        surrendered for registration of transfer or exchange for a
        Registered Security registered in a name other than that of the
        holder, no registration of transfer or exchange shall be made

             Security for transfer shall have certified to the Fiscal
             Agent in writing that such registered holder is transferring

                  (ii) The registered holder presenting such Restricted
             Security for transfer shall have certified to the Fiscal
             Agent in writing that the registered holder is transferring
             such Restricted Security outside the United States in a
             transaction meeting the requirements of Rule 904 of
             Regulation S under the Securities Act;

             Fiscal Agent in writing that such registered holder is
             transferring such Restricted Security to an "institutional
             accredited investor" (within the meaning of Rule 501(a)(1),
             (2), (3) or (7) under the Securities Act) in a transaction
             that is exempt from the registration requirements of the
             Securities Act; and (B) a broker or dealer registered under
             Section 15 of the Securities Exchange Act of 1934, as
             amended, shall have certified to the Fiscal Agent in writing
             that: (x) each person who will become a beneficial owner of
             the Restricted Security upon transfer is an institutional
             "accredited investor" (as such term is defined in Rule
                                        6PAGE
<PAGE>
             501(a)(1), (2), (3) or (7) under the Securities Act); (y) no
             general solicitation or general advertising was made or used
             by such broker or dealer in connection with the offer and
             sale of such Restricted Security to such person(s); and (z)
             such institutional accredited investor has been informed
             that the Securities have not been registered under the
             Securities Act and are subject to the restrictions on
             transfer set forth in the Securities and this Agreement;

                  (iv) The registered holder presenting such Restricted
             Security for transfer shall have certified to the Fiscal
             Agent in writing that the registered holder is transferring
             the Registered Security to the Company; or

                  (v)  The Fiscal Agent has received transfer
             documentation indicating, and a written opinion of U.S.
             counsel acceptable in form and substance to the Company and

             to, the registration requirements of the Securities Act.

             For purposes of this Section 3(b), any such certification to
        the Fiscal Agent in writing shall be in the form of the Transfer
        Notice set forth on the reverse of such Security.  In the case of
        transfer pursuant to the foregoing clauses (ii), (iii) or (v)
        above, the Company and the Fiscal Agent may require that the
        registered holder deliver an opinion of counsel, certifications
        or other information acceptable to them in form and substance.
        The Fiscal Agent shall notify the Company upon receipt of such
        Transfer Notice and the Company shall immediately advise the
        Fiscal Agent as to whether an opinion of counsel, certifications
        or other information as described herein shall be required for
        such transfer.  In addition, in the case of a transfer pursuant
        to the foregoing clause (iii) above, the transferor shall be
        required to deliver a letter from the transferee substantially in
        the form of Exhibit G hereto.

                  (c)  Bearer Securities may, at the option of the holder
        thereof, (with all unmatured coupons appertaining thereto and
        matured defaulted coupons appertaining thereto), be exchanged at,
        subject to applicable laws and regulations, the offices of the
        paying agencies in London and, if the Securities are listed on
        the Luxembourg Stock Exchange and so long as listed thereon,
        Luxembourg or as designated by the Company for such purposes
        pursuant to Section 12(g), for an equal aggregate principal
        amount of Registered Securities in denominations of $1,000 and
        integral multiples thereof without coupons and/or Bearer
        Securities of authorized denominations.  If such holder is unable
        to produce any such unmatured coupon or coupons or matured coupon
        or coupons in default, such exchange may be effected if the
        Bearer Securities are accompanied by payment in funds acceptable
        to the Company in an amount equal to the face amount of such
        missing coupon or coupons or the surrender of such missing coupon
        or coupons may be waived by the Company and the Guarantor if
                                        7PAGE

        there be furnished to them and the Fiscal Agent such security or
        indemnity as they may require to save each of them, the Fiscal
        Agent, the Paying Agent and any paying agency harmless.  If
        thereafter the holder of such Security shall surrender to any
        paying agency any such missing coupon in respect of which such a
        payment shall have been made, such holder shall be entitled to
        receive the amount of such payment from the Company; provided,
        however, that, except as otherwise provided in the form of Bearer
        Security set forth in Exhibit A hereto, interest represented by
        coupons shall be payable only upon presentation and surrender of
        those coupons outside of the United States, its territories and
        its possessions.  Bearer Securities and coupons are transferable
        upon delivery.

             Registered Securities may, at the option of the holder
        thereof, be exchanged at the Corporate Trust Office of the Fiscal
        Agent in New York City, or subject to applicable laws and
        regulations, the offices of the paying agencies in London and, if
        the Securities are listed on the Luxembourg Stock Exchange and so
        long as listed thereon, Luxembourg or as designated by the
        Company for such purposes pursuant to Section 12(g), for an equal
        aggregate principal amount of Registered Securities of different
        denominations.  Registered Securities shall not be exchangeable
        for Bearer Securities.  Whenever any Registered Securities are so
        surrendered for exchange, the Company shall execute, and the
        Fiscal Agent shall authenticate and deliver, the Registered
        Securities which the holder making the exchange is entitled to
        receive, having endorsed thereon a Guarantee duly executed by the
        Guarantor.  If the holder thereof requests in writing that such
        Registered Security be exchanged for an interest in the Rule 144A
        Global Security, such Registered Security will be exchangeable
        into an equal aggregate principal amount of beneficial interest
        in the Rule 144A Global Security; provided, however, that, if
        such Registered Security is a Restricted Security, such exchange
        may only be made if such holder certifies to the Fiscal Agent in
        writing that such holder is a QIB by completing the Transfer
        Notice on the reverse of such Security.  Upon any exchange as
        provided in the immediately preceding sentence, the Fiscal Agent
        shall cancel such Registered Security and cause, or direct any
        custodian for the Rule 144A Global Security to cause, in
        accordance with the standing instructions and procedures existing
        between the Depository and any such custodian, the aggregate
        principal amount of Securities represented by the Rule 144A
        Global Security to be increased accordingly.  If no Rule 144A
        Global Securities are then outstanding, the Company shall issue
        and the Fiscal Agent shall authenticate a new Rule 144A Global
        Security in the appropriate principal amount, having endorsed
        thereon a Guarantee duly executed by the Guarantor.

             Any person having a beneficial interest in a Rule 144A
        Global Security may upon request exchange such beneficial
        interest for a Registered Security only as provided in this
        paragraph.  Upon receipt by the Company and the Fiscal Agent of
        (i) written or electronic instructions from the Depository or its
                                        8PAGE
<PAGE>
        nominee (or such other form of instructions as is customary) on
        behalf of any person having a beneficial interest in a Rule 144A
        Global Security and upon receipt by the Fiscal Agent of a written
        order of such person containing registration instructions and
        (ii) in the case of a Restricted Security, the following
        additional information and documents (all of which may be
        submitted by facsimile):

                  (A)  if such beneficial interest is being transferred
                       to the person designated as being the beneficial
                       owner, a certification to that effect from such
                       person; or

                  (B)  if such beneficial interest is being transferred
                       to a person other than the person designated as
                       being the beneficial owner, the provisions of
                       Section 3(b) hereof have been satisfied;

        in which case the Fiscal Agent or any custodian for the Rule 144A
        Global Security, at the direction of the Fiscal Agent, shall, in
        accordance with the standing instructions and procedures existing
        between the Depository and such custodian, cause the aggregate
        principal amount of the Rule 144A Global Security to be reduced
        accordingly and, following such reduction, the Company shall
        execute and the Fiscal Agent shall authenticate and deliver to
        such person or the transferee, as the case may be, a Registered
        Security in the appropriate principal amount, having endorsed
        thereon a Guarantee duly executed by the Guarantor and, if such
        Registered Security is a Restricted Security, including the
        appropriate legend.  Registered Securities issued in exchange for
        a beneficial interest in the Rule 144A Global Security pursuant
        to this paragraph shall be registered in such names and such
        authorized denominations as shall be instructed to the Fiscal
        Agent.  The Fiscal Agent shall deliver such Registered Securities
        to the persons in whose names such Securities are so registered.

                  (d)  Notwithstanding any other provision of this
        Agreement (other than the provisions set forth in Section 3(e)
        hereof), the Rule 144A Global Security may not be transferred as
        a whole except by the Depository to a nominee of the Depository
        or by a nominee of the Depository to the Depository or another
        nominee of the Depository or by the Depository or any such
        nominee to a successor Depository or a nominee of such successor
        Depository.

                  (e)  If at any time either (i) the Depository for the
        Rule 144A Global Security notifies the Company and the Guarantor
        that the Depository is unwilling or unable to continue as
        Depository for the Rule 144A Global Security and a successor
        Depository for the Rule 144A Global Security is not appointed by
        the Company and the Guarantor within 90 days after delivery of
        such notice, or (ii) the Company and the Guarantor, at their sole
        discretion, notify the Fiscal Agent in writing that the Company
        elects to cause the issuance of Registered Securities under this
                                        9PAGE
<PAGE>
        Agreement, then the Company shall execute, and the Fiscal Agent
        shall authenticate and deliver, Registered Securities in an
        aggregate principal amount equal to the principal amount of the
        Rule 144A Global Security in exchange for such Rule 144A Global
        Security.

                  (f)  Each certificate evidencing Restricted Securities
        shall bear a legend in substantially the following form:

             THIS SECURITY (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED
             UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED
             (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND
             NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION
             HEREIN MAY BE OFFERED, SOLD OR OTHERWISE TRANSFERRED WITHIN
             THE "UNITED STATES" OR TO "U.S. PERSONS" (AS DEFINED IN
             REGULATION S UNDER THE SECURITIES ACT) IN THE ABSENCE OF
             SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM.
             EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE
             SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS
             OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A
             THEREUNDER.  THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE
             HEREOF, REPRESENTS, ACKNOWLEDGES AND AGREES FOR THE BENEFIT
             OF THE COMPANY THAT: (I) IT HAS ACQUIRED A "RESTRICTED"
             SECURITY WHICH HAS NOT BEEN REGISTERED UNDER THE SECURITIES
             ACT; (II) IT WILL NOT OFFER, SELL OR OTHERWISE TRANSFER THIS
             SECURITY PRIOR TO THE DATE WHICH IS THREE YEARS (OR THE THEN
             APPLICABLE HOLDING PERIOD UNDER RULE 144(K) UNDER THE
             SECURITIES ACT (OR SUCCESSOR PROVISION)) AFTER THE DATE OF
             ORIGINAL ISSUANCE HEREOF AND THE LAST DATE ON WHICH THE
             COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF
             SUCH RESTRICTED SECURITIES (OR ANY PREDECESSOR), EXCEPT (A)
             TO THE COMPANY, (B) PURSUANT TO A REGISTRATION STATEMENT
             WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT,
             (C) FOR SO LONG AS THIS SECURITY IS ELIGIBLE FOR RESALE
             PURSUANT TO RULE 144A, TO A PERSON WHO THE SELLER REASONABLY
             BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN
             RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING
             THE REQUIREMENTS OF RULE 144A, (D) OUTSIDE THE UNITED STATES
             IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 904 UNDER
             THE SECURITIES ACT OR (E) PURSUANT TO ANOTHER AVAILABLE
             EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
             SECURITIES ACT AND, IN EACH CASE, IN ACCORDANCE WITH THE
             APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES
             OR ANY OTHER APPLICABLE JURISDICTION; AND (III) IT WILL, AND
             EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER
             FROM IT OF THIS SECURITY OF THE RESALE RESTRICTIONS SET
             FORTH IN (II) ABOVE.  ANY OFFER, SALE OR OTHER DISPOSITION
             PURSUANT TO THE FOREGOING CLAUSE (II)(D) AND (E) IS SUBJECT
             TO THE RIGHT OF THE ISSUER OF THIS SECURITY AND THE FISCAL
             AGENT FOR SUCH ISSUER TO REQUIRE THE DELIVERY OF AN OPINION
             OF COUNSEL, CERTIFICATIONS OR OTHER INFORMATION ACCEPTABLE
             TO THEM IN FORM AND SUBSTANCE.

                  (g)  The restrictions imposed by Section 3(b) upon the
        transferability of any particular Restricted Security shall cease
        and terminate when such Restricted Security has been sold
        pursuant to an effective registration statement under the
        Securities Act or transferred pursuant to Rule 144 under the
        Securities Act (or any successor provision thereto), unless the
        holder is an affiliate of the Company within the meaning of said
        Rule 144 (or such successor provision).  Any Restricted Security
        as to which such restrictions on transfer shall have expired in
        accordance with their terms or shall have terminated may, upon
        surrender of such Restricted Security for exchange to the Fiscal
        Agent in accordance with the provisions of this Section 3(g)
        (accompanied, in the event that such restrictions on transfer
        have terminated by reason of a transfer pursuant to Rule 144 (or
        any successor provision), by an opinion of counsel reasonably
        acceptable to the Company, addressed to the Company and the
        Fiscal Agent and in form and scope satisfactory to the Company,
        to the effect that the transfer of such Restricted Security has
        been made in compliance with Rule 144 (or such successor
        provision)), be exchanged for a new Registered Security, of like
        tenor and aggregate principal amount, which shall not bear the
        restrictive legend required by Section 3(f) hereof.  The Company
        shall promptly inform the Fiscal Agent in writing of the
        effective date of any registration statement registering the
        Securities under the Securities Act.

                  (h)  The transfer and exchange of the Rule 144A Global
        Security or beneficial interests therein shall be effected
        through the Depository, in accordance with this Agreement and the
        procedures of the Depository therefor, which shall include
        restrictions on transfer comparable to those set forth herein to
        the extent required by the Securities Act.

                  (i)  At such time as all beneficial interests in the
        Rule 144A Global Security have either been exchanged for
        Registered Securities, redeemed, repurchased or canceled, the
        Rule 144A Global Security shall be returned to or retained and
        canceled by the Fiscal Agent.  At any time prior to such
        cancellation, if any beneficial interest in the Rule 144A Global
        Security is exchanged for Registered Securities, redeemed,
        repurchased or canceled, the principal amount of Securities
        represented by the Rule 144A Global Security shall be reduced
        accordingly and an endorsement shall be made on the Rule 144A
        Global Security, by the Fiscal Agent or any custodian therefor,
        at the direction of the Fiscal Agent, to reflect such reduction.

                  (j)  All Securities issued upon any registration of
        transfer or exchange of Securities shall be the valid obligations
        of the Company, and the Guarantees endorsed thereon shall be the
        valid obligations of the Guarantor, evidencing the same
        obligations, and entitled to the same benefits under this
        Agreement, as the Securities surrendered upon such registration
        of transfer or exchange.

                  (k)  Every Registered Security presented for
        registration of transfer or surrendered for exchange shall be
        duly endorsed, or be accompanied by a written instrument of
        transfer in form satisfactory to the Company, the Fiscal Agent
        and the Transfer Agent to which such Security is presented or
        surrendered and the Security Registrar, duly executed by the
        holder thereof or his attorney duly authorized in writing.  All
        such instruments shall comply with the applicable provisions of
        this Section 3. The registration of the transfer of a Registered
        Security by the Security Registrar shall be deemed to be the
        written acknowledgment of such transfer on behalf of the Company.

                  (1)  No service charge shall be made for any
        registration of transfer or exchange (other than the cost of
        delivery), but the Company or the Transfer Agent may require
        payment of a sum sufficient to cover any tax or other
        governmental charge that may be imposed in connection with any
        registration of transfer or exchange of Securities, other than
        exchanges pursuant to Section 4 hereof or not involving any
        registration of transfer.

                  (m)  Neither the Company nor the Fiscal Agent nor any
        of the offices or agencies designated for the purposes specified
        in Section 12(f) nor any Transfer Agent shall be required (i) to
        exchange Bearer Securities for Registered Securities during the
        period between the close of business on any Record Date (as
        defined in Section 5(c) hereof) and the opening of business on
        the next succeeding interest payment date, (ii) to exchange any
        Bearer Security (or portion thereof) for a Registered Security if
        the Company shall determine and inform the Fiscal Agent in
        writing that, as a result thereof, the Company would incur
        adverse consequences under the United States Federal income tax
        laws at the time of such exchange, or (iii) in the event of a
        redemption in part, (A) to register the transfer of Registered
        Securities or to exchange any Bearer Securities for Registered
        Securities for a period of 15 days immediately preceding the date
        notice is given pursuant to Section 3(f) of the Registered
        Securities and the Bearer Securities identifying the serial
        numbers of any Securities to be redeemed, or (B) to register the
        transfer of or exchange of any Registered Security so selected
        for redemption in whole or in part, except portions not being
        redeemed of Securities being redeemed in part, or (C) to exchange
        any Bearer Security called for redemption; provided, however,
        that a Bearer Security called for redemption may be exchanged, on
        the terms and conditions set forth above, for a Registered
        Security that is simultaneously surrendered, with written
        instruction for payment on the date fixed for redemption, unless
        the redemption date is after a Record Date and on or before the
        next succeeding interest payment date, in which case such
        exchange may be made only prior to the Record Date immediately
        preceding the redemption date.

             4.   Closing Date; Exchange of Regulation S Global Security.

                  (a)  At any time and from time to time after the
        execution and delivery of this Agreement, the Company may deliver
        Securities executed by the Company in accordance with this
        Agreement bearing the Guarantees of the Guarantor endorsed
        thereon to the Fiscal Agent for authentication together with an
        officer's certificate of the Company directing such
        authentication, and the Fiscal Agent shall thereupon authenticate
        and make such Securities available for delivery upon and in
        accordance with the written order of the Company.  No Security
        shall be valid or enforceable for any purpose unless and until
        the certificate of authentication thereon shall have been
        manually signed by a duly authorized signatory of the Fiscal
        Agent and such duly executed certificate of authentication on any
        Security shall be conclusive evidence that the Security has been
        duly authenticated and delivered hereunder.  The Regulation S
        Global Security, the Rule 144A Global Security and the Registered
        Accredited Investor Securities will be issued upon payment to the
        Company or its order in United States dollars in same-day funds
        by check or wire transfer to a United States dollar account
        designated by the Company, at 4:00 p.m., London time, on May 2,
        1996, or at such other time on the same or such other date, not
        later than 5:00 p.m., London time, on the fourth Business Day (as
        such term is defined in Section 5(h) hereof) in London
        thereafter, as the Managers and the Company may agree (the
        "Closing Date").  Such payment will be made (1) upon
        authorization from the Managers, (2) against delivery as provided
        in Section 4(b) hereof of the amount, if any, of Rule 144A
        Securities and Registered Accredited Investor Securities as the
        Managers may request and as they shall direct, and (3) against
        delivery of the Regulation S Global Security for the balance of
        the Securities to The Chase Manhattan Bank, N.A., London office,
        as depositary (the "Common Depositary") for Morgan Guaranty Trust
        Company of New York, Brussels office, as operator of the
        Euroclear System (the "Euroclear Operator"), and Cedel Bank
        societe anonyme ("CEDEL").  The Regulation S Global Security
        shall be held on deposit with the Common Depositary for the
        accounts of the Euroclear Operator and Cedel, for credit to the
        Managers' respective Securities Clearance Accounts (or to such
        other accounts as the Lead Manager may have specified) with the
        Euroclear Operator or Cedel.

                  (b)  On the Closing Date, the Company shall execute and
        deliver to (i) the Managers, at the office of an affiliate of the
        Lead Manager (as defined in the Subscription Agreement) in New
        York, Registered Accredited Investor Securities bearing the
        Guarantees of the Guarantor endorsed thereon (which shall have
        been duly authenticated by the Fiscal Agent and which may be in
        typewritten form) in respect of the Accredited Investor
        Securities and (ii) the Depositary, at its office in New York,
        the Rule 144A Global Security bearing the Guarantee of the
        Guarantor endorsed thereon (which shall have been duly
                                       13PAGE
<PAGE>
        authenticated by the Fiscal Agent and which may be in typewritten
        form) in respect of the Rule 144A Securities.

                  (c)  On or before the Exchange Date, the Company will
        execute and deliver to the Fiscal Agent, at its office in London,
        definitive Registered Regulation S Securities and Bearer
        Securities bearing the Guarantees of the Guarantor endorsed
        thereon in the aggregate principal amount outstanding in the
        Regulation S Global Security and in such proportion of Registered
        Regulation S Securities to Bearer Securities as the Fiscal Agent
        may specify.  "Exchange Date" means the date following the
        expiration of the 40-day period commencing on the Closing Date.
        On or after the Exchange Date, the Regulation S Global Security
        may be surrendered to the Fiscal Agent to be exchanged, as a
        whole or in part, for definitive Bearer Securities without
        charge, and the Fiscal Agent shall authenticate and deliver, in
        exchange for such Regulation S Global Security or the portions
        thereof to be exchanged, an equal aggregate principal amount of
        definitive Bearer Securities, but only upon presentation to the
        Fiscal Agent at its office in London of a certificate of the
        Euroclear Operator or Cedel with respect to the Regulation S
        Global Security or portions thereof being exchanged,
        substantially in the form of Exhibit C hereto, to the effect that
        it has received a certificate or certificates in substantially
        the form set forth in Exhibit D hereto dated no earlier than 15
        days prior to the Exchange Date and signed by the person
        appearing in its records as the owner of the Regulation S Global
        Security or portions thereof being exchanged. Similarly, on or
        after the Exchange Date, portions of the Regulation S Global
        Security may be exchanged for an equal aggregate principal amount
        of definitive Registered Regulation S Securities upon
        presentation to the Fiscal Agent of a certificate substantially
        in the form of Exhibit F hereto, to the effect that it has
        received a certificate or certificates in substantially the form
        set forth in Exhibit E hereto dated no earlier than 15 days prior
        to the Exchange Date and signed by the person appearing in its
        records as the owner of the Regulation S Global Security or
        portions thereof being exchanged. In addition, on or after the
        Exchange Date, (or if permitted by the Company and the Fiscal
        Agent, before the Exchange Date), portions of the Regulation S
        Global Security may be exchanged for a beneficial interest in an
        equal aggregate principal amount of the Rule 144A Global Security
        (which portion shall be a Restricted Security) upon
        certifications acceptable to the Company and to the Fiscal Agent
        to the effect that the person(s) beneficially owning such portion
        of the Rule 144A Global Security are QIBs.

                  (d)  The definitive Securities and coupons shall be
        printed, lithographed or engraved or produced by any combination
        of these methods or may be produced in any other manner permitted
        by the rules of any securities exchange on which the Securities
        may be listed, all as determined by the officers executing such
        Securities and coupons, as evidenced by such execution.

                  (e)  Only Bearer Securities may be issued upon receipt
        by the Euroclear Operator or Cedel of a certificate or
        certificates in the form of Exhibit D hereto.  Bearer Securities
        will be delivered only outside the United States, its territories
        or its possessions.  Only Registered Securities may be issued
        upon receipt by the Euroclear Operator or Cedel of a certificate
        or certificates in the form of Exhibit E hereto.

                  (f)  The delivery to the Fiscal Agent by the Euroclear
        Operator or Cedel of any certificate referred to above may be
        relied upon by the Company and the Fiscal Agent as conclusive
        evidence that a corresponding certificate or certificates has or
        have been delivered to the Euroclear Operator or Cedel pursuant
        to the terms of this Agreement.  The Fiscal Agent shall receive
        such certificate on behalf of the Company and shall promptly
        deliver the original certificate to the Company, retaining a copy
        of such certificate for its records.

                  (g)  Upon any such exchange of a portion of the
        Regulation S Global Security for a definitive Bearer Security or
        Securities or a definitive Registered Regulation S Security or
        Securities or a beneficial interest in the Rule 144A Global
        Security, the Regulation S Global Security shall be endorsed by
        the Fiscal Agent to reflect the reduction of its principal amount
        by an amount equal to the aggregate principal amount of such
        definitive Security or Securities.  Until so exchanged in full,
        the Regulation S Global Security shall in all respects be
        entitled to the same benefits under this Agreement as definitive
        Securities authenticated and delivered hereunder.

             5.   Payment.

                  (a)  The Company will pay or cause to be paid to the
        Paying Agent the amounts, at the times and for the purposes, set
        forth herein and in the text of the Securities, and the Company
        hereby authorizes and directs the Paying Agent to make payment of
        the principal of, premium, if any, and interest on and Additional
        Amounts (as defined in Section 2 of the Registered Securities and
        the Bearer Securities), if any, on the Securities from such
        payments.

                  (b)  At least 15 days prior to the date on which any
        payment of Additional Amounts shall be required to be made
        pursuant to Section 2 of the Registered Securities and the Bearer
        Securities, the Company will furnish the Paying Agent, each other
        paying agency of the Company and the Fiscal Agent with a
        certificate of one of its duly authorized officers instructing
        the Paying Agent and each other paying agency of the Company as
        to the amounts required (i) to be deducted or withheld for or on
        account of any taxes described in Section 2 of the Registered
        Securities and the Bearer Securities from a payment to be made on
        that date and (ii) to be paid to each holder of Securities or
        coupons as Additional Amounts pursuant to that Section.  If the
        foregoing amounts are not uniform for all holders, then the
                                       15PAGE
<PAGE>
        Company's certificate shall specify by country of residence or
        other factor the amounts required to be deducted or withheld and
        to be paid as Additional Amounts for each holder or class of
        holders of the Securities or coupons.  In the absence of its
        receipt of any such  certificate from the Company, the Paying
        Agent may make payment without deduction or withholding.  The
        Company and the Guarantor hereby agree to indemnify the Paying
        Agent, each other paying agency of the Company and the Fiscal
        Agent for, and to hold them harmless against, any loss, liability
        or expense reasonably incurred without gross negligence or bad
        faith on their part, arising out of or in connection with actions
        taken or omitted by any of them in reliance on any certificate
        furnished pursuant to this Section.

                  (c)  Interest on any Registered Security that is
        payable, and is punctually paid or duly provided for, on any
        interest payment date shall be paid to the person in whose name
        that Security is registered at the close of business on the April
        15 or October 15 immediately preceding such interest payment date
        (each a "Record Date"), even if such Registered Security is
        canceled, upon redemption, conversion or otherwise, after such
        Record Date.  In case a Bearer Security is surrendered for
        exchange for a Registered Security after the close of business on
        any Record Date and before the opening of business on the next
        succeeding interest payment date, the Fiscal Agent shall not be
        required to perform such transfer or exchange of such Security.

                  (d)  Interest on any Registered Security that is
        payable upon conversion in accordance with Section 7(a) hereof
        shall be paid to the person in whose name that Security is
        registered immediately prior to the conversion, provided that if
        a Registered Security is converted after the close of business on
        a Record Date and before the opening of business on the next
        succeeding interest payment date, accrued interest shall be paid
        on the next succeeding interest payment date to the person in
        whose name that Security is registered at the close of business
        on that Record Date.

                  (e)  Any interest on any Registered Security that is
        payable, but is not punctually paid or duly provided for, on any
        interest payment date shall forthwith cease to be payable to the
        registered holder thereof on the relevant regular record date by
        virtue of having been such holder, and such defaulted interest
        may be paid by the Company to the registered holder of such
        registered Security on a subsequent record date established by
        the Company in any lawful manner if, after notice given by the
        Company to the Fiscal Agent of the proposed payment pursuant to
        this clause, such manner of payment shall be deemed practicable
        by the Fiscal Agent.

                  (f)  Subject to the foregoing provisions of this
        Section 5, each Security delivered under this Agreement upon
        registration of transfer of or in exchange for or in lieu of any
                                       16PAGE
<PAGE>
        other Security shall carry all the rights to interest accrued and
        unpaid, and to accrue, which were carried by such other Security.

                  (g)  In order to provide for the payment of the
        principal of, premium, if any, and interest on the Securities as
        the same shall become due and payable, the Company shall pay to
        the Paying Agent at its office in London, in such coin or
        currency of the United States of America as at the time of
        payment is legal tender for the payment of public and private
        debts therein, and in same day funds, the following amounts (and
        the Company shall give notice to the Fiscal Agent at least one
        full Business Day prior to the date payment is due to the Paying
        Agent as to the means of such payment), to be held and applied by
        the Paying Agent as hereinafter set forth:

                  (i)  The Company shall pay to the Paying Agent on the
             Business Day immediately prior to each interest payment date
             in same day funds an amount sufficient to pay the interest
             due (and Additional Amounts, if any) on all the Securities
             outstanding on such interest payment date and the Paying
             Agent shall apply the amounts paid to it to the payment of
             such interest (and Additional Amounts, if any) on such
             interest payment date.

                  (ii) Upon presentment for conversion of any Securities
             pursuant to Section 7(a) hereof (except as described in the
             proviso to Section 5(d)), the Paying Agent shall promptly
             notify the Company of the amount of any accrued interest due
             and owing thereon.  Within four Business Days of such
             notification, the Company shall pay to the Paying Agent an
             amount sufficient to pay the accrued interest due on such
             Securities (and Additional Amounts, if any, thereon), and
             the Paying Agent shall apply the amounts so paid to it to
             the payment of such accrued interest (and Additional
             Amounts, if any, thereon) in accordance with the terms of
             the Securities.

                  (iii)  If the Company shall elect, or shall be
             required, to redeem the Securities in accordance with
             Section 6 hereof, the Company will pay to the Paying Agent
             on the Business Day immediately prior to the date fixed for
             redemption thereof in same day funds an amount sufficient
             (with any amount then held by the Paying Agent and available
             for the purpose) to pay the redemption price of the
             Securities called for redemption on the redemption date or
             entitled to be redeemed, together with accrued interest
             thereon (and Additional Amounts, if any, thereon) to the
             date fixed for redemption and not paid pursuant to clause
             (g)(i) of this Section 5, and the Paying Agent shall apply
             such amount to the payment of the redemption price and
             accrued interest thereon (and Additional Amounts, if any,
             thereon) in accordance with the terms of the Securities.

<PAGE>
                  (iv) On the Business Day immediately prior to the
             maturity date of the Securities, the Company shall pay to
             the Paying Agent in same day funds an amount which, together
             with any amounts then held by the Paying Agent, and
             available for payment thereof, shall be equal to the entire
             amount of principal and interest (and Additional Amounts, if
             any) to be due on such maturity date on all the Securities
             then outstanding, and the Paying Agent shall apply such
             amount to each payment of the principal of and interest on
             (and Additional Amounts, if any, on) the Securities in
             accordance with the terms of the Securities.

                  (h)  Notwithstanding anything in this Section to the
        contrary, if any payment of interest or premium or principal (or
        Additional Amounts, if any) is due on a day that is not a
        Business Day, payment shall be made on the next succeeding
        Business Day, with the same effect as if made on the day such
        payment was due, and no interest shall accrue for the period
        after such date.  A "Business Day" is defined, with respect to
        any act to be performed pursuant hereto or to the Securities, as
        any day which is not a Saturday, Sunday or a day on which banking
        institutions in the place where such act is to occur are
        authorized or obligated by applicable law, regulation or
        executive order to close.

             6.   Redemption.

                  (a)  If, under the circumstances described in Section 3
        of the Registered Securities and Bearer Securities, the Company
        shall elect or be required to redeem outstanding Securities, the
        following provisions shall be applicable:

                  (i)  The Company shall, at least 35 days in the case of
             a redemption in whole or 75 days in the case of a redemption
             in part (or such shorter period as shall be reasonably
             acceptable to the Fiscal Agent) before the date designated
             for such redemption, give written notice to the Agents of
             its election to redeem the Securities on the redemption date
             specified in such notice and state in such notice that the
             conditions precedent to such redemption have occurred and
             describe them, and in case of redemptions pursuant to
             Section 3(b) of the Registered Securities and the Bearer
             Securities, shall provide to the Fiscal Agent an opinion of
             counsel satisfactory to the Fiscal Agent stating that the
             legal conditions precedent to the right of the Company to
             effect such redemption have occurred, and shall request the
             Fiscal Agent to arrange for publication and mailing of the
             notice specified in clause (a) (ii) below.

                  (ii) In case the Company shall give notice to the
             Agents of its election to redeem the Securities, the Fiscal
             Agent shall cause to be published on behalf of and at the
             expense of the Company a notice of redemption in accordance
             with the provisions of Section 3 of the Registered
                                       18PAGE

             Securities and Bearer Securities and shall mail by
             first-class mail a copy of the notice to each holder of a
             Registered Security at the address of such holder as it
             shall appear in the Security Register.  The Fiscal Agent
             shall send a copy of such notice of redemption to the
             Company, the Guarantor, the Paying Agent (if different from
             the Fiscal Agent) and each other paying agency of the
             Company.

                  (iii)  Such notice shall be published on behalf and at
             the expense of the Company in an Authorized Newspaper (as
             defined in Section 19 hereof) on a Business Day in New York
             City and in London and, if the Securities are listed on the
             Luxembourg Stock Exchange and so long as listed thereon, in
             an Authorized Newspaper in Luxembourg, or, if publication in
             either London or Luxembourg is not practical, in an
             Authorized Newspaper in any country in Western Europe, as
             set forth in Section 19 of this Agreement and Section 3 of
             the Registered Securities and Bearer Securities.  In the
             case of a redemption in whole, notice will be given once not
             more than 60 nor less than 30 days prior to the date fixed
             for redemption.  In the case of partial redemption, notice
             will be given twice, the first such notice to be given not
             more than 75 nor less than 60 days prior to the date fixed
             for redemption and the second such notice to be given not
             more than 60 and not less than 30 days prior to the date
             fixed for redemption.  The Fiscal Agent shall notify the
             Company promptly of the portions of outstanding Securities
             to be called for redemption as determined pursuant to
             Section 3(a) of the Registered Securities and Bearer
             Securities.

                  (b)  Under the circumstances described in Section 3(d)
        of the Registered Securities and Bearer Securities concerning the
        redemption of outstanding Securities at the option of the holders
        thereof, the following provisions shall be applicable:

                  (i)  The Company shall give notice to the Fiscal Agent
             of the occurrence of a Redemption Event (as defined in
             Section 3(d) of the Registered Securities and Bearer
             Securities) immediately upon the occurrence of such
             Redemption Event.  Such notice shall state:

                       (A)  The nature of the Redemption Event;

                       (B)  The Holder Redemption Date (as defined in
                  Section 3(d) of the Registered Securities and Bearer
                  Securities) in respect of such Redemption Event; and

                       (C)  The redemption price as set forth in Section
                  3(d) of the Registered Securities and Bearer
                  Securities.

                  (ii) The Fiscal Agent shall cause to be published on
             behalf of the Company a notice of entitlement to redeem in
             accordance with the provisions of Section 3 of the
             Registered Securities and Bearer Securities and shall mail
             by first-class mail a copy of such notice to each holder of
             a Registered Security at the address of such holder as it
             shall appear in the Security Register.  The Fiscal Agent
             shall send a copy of such notice of entitlement to redeem to
             the Company, the Guarantor, the Paying Agent (if different
             from the Fiscal Agent) and each other paying agency of the
             Company hereunder.  Such notice shall be published on behalf
             and at the expense of the Company in Authorized Newspapers
             on a Business Day in New York City and in London and, if the
             Securities are listed on the Luxembourg Stock Exchange and
             so long as listed thereon, in an Authorized Newspaper in
             Luxembourg, or, if either publication in London or
             Luxembourg is not practical, in an Authorized Newspaper in
             any country in Western Europe, as set forth in Section 19 of
             this Agreement.  Notice shall be given not later than 10
             days after the later of the Exchange Date or the date of the
             occurrence of a Redemption Event.

                  (iii)  Upon the deposit of any of the Registered
             Securities or Bearer Securities with the agency designated
             by the Company as the place for payment of the Registered
             Securities and Bearer Securities together with a duly signed
             and completed redemption notice in the form set forth on the
             reverse of the Bearer Securities and Registered Securities,
             all in accordance with the provisions of Section 3 of the
             Registered Securities and Bearer Securities, the holder of
             such Registered Security and Bearer Security shall be
             entitled to receive a non-transferable receipt evidencing
             such deposit.

                  (iv) The Fiscal Agent shall notify the Company on each
             Business Day in the five Business Days prior to the Holder
             Redemption Date for outstanding Securities to be redeemed
             under this Section 6(b) of the amount required to redeem
             such Securities.

             7.   Conversion of Securities.

                  (a)  Subject to and upon compliance with the provisions
        of this Section 7, at the option of the holder thereof, any
        outstanding Registered Security or Bearer Security or, in the
        case of any outstanding Registered Security or Bearer Security of
        a denomination other than $1,000, any portion of the principal
        amount thereof which is $1,000 or an integral multiple of $1,000,
        may be converted into shares of the Company's common stock, par
        value $.10 per share ("Common Stock"), issuable upon conversion
        of the Securities, at the principal amount thereof, or of such
        portion thereof, into fully paid and nonassessable shares of
        Common Stock ("Conversion Shares") as set forth in the Registered
        Securities and Bearer Securities.  Such Registered Securities or

                                       20PAGE
<PAGE>
        Bearer Securities may be converted on or after the date which is
        the latest of: (i) the Exchange Date, (ii) July 15, 1996 and
        (iii) the date of the effectiveness of the Registration Statement
        to be filed by the Company under the Securities Act relating to
        the Common Stock issuable upon conversion of the Restricted
        Securities (the "Registration Date"), and in any event prior to
        redemption or maturity.  The right to convert Securities called
        for redemption will terminate at the close of business on the
        fifteenth day next preceding the date fixed for redemption (or if
        such date is not a Business Day, then the next succeeding
        Business Day), and will be lost if not exercised prior to that
        time.  No payment or adjustment shall be made upon any conversion
        on account of any dividends on the Common Stock issued upon
        conversion.  Accrued interest from the immediately preceding
        interest payment date until the conversion date (and Additional
        Amounts, if any, thereon) will be paid to the holder, through the
        Paying Agent, in the same manner as payments of interest, within
        five Business Days after the conversion date, provided that if a
        Registered Security is converted after the close of business on a
        Record Date and before the opening of business on the next
        succeeding interest payment date, accrued interest shall be paid
        on the next succeeding interest payment date to the person in
        whose name that Security is registered at the close of business
        on that Record Date.  The price at which Conversion Shares shall
        be delivered upon conversion (herein called the "Conversion
        Price") shall be initially U.S. $15.90 per share of Common Stock.
        The Conversion Price shall be adjusted in certain instances as
        provided in paragraphs (c)(i), (ii), (iii), (iv), (vi) and (vii)
        of Section 4 of the Registered Securities and Bearer Securities.

                  (b)  In order to exercise the conversion privilege, the
        holder of any Security to be converted shall surrender such
        Security, or, if less than the entire principal amount of a
        Registered Security or Bearer Security of a denomination other
        than $1,000 is to be converted, the portion thereof to be
        converted, together with all unmatured coupons and any matured
        coupons in default appertaining thereto, at the office of the
        Conversion Agent or any office or agency of the Company
        maintained for that purpose pursuant to Section 12(f) hereof,
        accompanied by a duly signed and completed Conversion Notice, in
        substantially the form set forth in the Registered Securities and
        Bearer Securities, to the Company, at such office or agency that
        the holder elects to convert such Security (or specified portion
        thereof).

                  (c)  Securities shall be deemed to have been converted
        immediately prior to the close of business on the day of
        surrender of such Securities for conversion in accordance with
        the foregoing provisions, and at such time the rights of the
        holders of such Securities as holders shall cease, and the person
        or persons entitled to receive the Common Stock issuable upon
        conversion shall be treated for all purposes as the record holder
        or holders of such Common Stock at such time.  As promptly as
        practicable on or after the conversion date, the Company shall
                                       21PAGE
<PAGE>
        cause to be issued or delivered at such office or agency a
        certificate or certificates for the number of full shares of
        Common Stock issuable or deliverable upon conversion, together
        with payment, in lieu of any fraction of a share, as provided
        below.  The Paying Agent shall, within five business days after
        the conversion date, make a payment for the accrued interest
        thereon (and Additional Amounts, if any, thereon), except as
        otherwise provided in this Section 7.

                  (d)  In the case of any Registered Security or Bearer
        Security of a denomination other than $1,000 which is converted
        in part only, upon such conversion the Company shall execute and
        the Fiscal Agent shall authenticate and deliver to the holder
        thereof, at the expense of the Company, a new Security or
        Securities of any authorized kind or denomination as requested by
        such holder, in aggregate principal amount equal to the
        unconverted portion of the principal amount of such Security,
        having endorsed thereon a Guarantee duly executed by the
        Guarantor.

                  (e)  No fractional shares of Common Stock shall be
        issued or delivered upon conversion of Securities.  If more than
        one Security shall be surrendered for conversion at one time by
        the same holder, the number of full shares of Common Stock which
        shall be issuable or deliverable upon conversion thereof shall be
        computed on the basis of the aggregate principal amount of the
        Securities (or, in the case of Registered Securities or Bearer
        Securities of a denomination other than $1,000, specified
        portions thereof) so surrendered.  Instead of any fractional
        share of Common Stock which would otherwise be issuable or
        deliverable upon conversion of any Security or Securities (or, in
        the case of Registered Securities or Bearer Securities of a
        denomination other than $1,000, specified portions thereof), the
        Company shall pay a cash adjustment in respect of such fraction
        in an amount equal to the same fraction of the Closing Price (as
        defined in Section 4(c)(v) of the Registered Securities and
        Bearer Securities) for a share of Common Stock at the close of
        business on the day preceding the day of conversion.

                  (f)  Whenever the Conversion Price is adjusted as
        provided in the Registered Securities and Bearer Securities:

                       (i)  the Company shall compute the adjusted
             Conversion Price in accordance with the terms of the
             Registered Securities and Bearer Securities and shall
             prepare a certificate signed by the President, any Vice
             President or the Treasurer of the Company setting forth the
             adjusted Conversion Price and showing in reasonable detail
             the facts upon which such adjustment is based, and such
             certificate shall forthwith be filed with the Conversion
             Agent and at each office or agency maintained for the
             purpose of conversion of Securities pursuant to Section
             12(f) hereof; and
                                       22PAGE
<PAGE>
                       (ii) a notice stating that the Conversion Price
             has been adjusted and setting forth the adjusted Conversion
             Price shall forthwith be prepared, and, as soon as
             practicable after it is prepared, the Company shall promptly
             cause a notice setting forth the adjusted Conversion Price
             to be given to the holders of the Securities.  Such notice
             shall be published on behalf and at the expense of the
             Company in Authorized Newspapers on a Business Day in New
             York City and in London and, if the Securities are listed on
             the Luxembourg Stock Exchange and so long as listed thereon,
             in an Authorized Newspaper in Luxembourg, or, if publication
             in either London or Luxembourg is not practical, in an
             Authorized Newspaper in any country in Western Europe, as
             set forth in Section 19 of this Agreement and Section 4 of
             the Registered Securities and Bearer Securities.

                  (g)  In case:

                       (i)  the Company shall declare a dividend (or any
             other distribution) on its Common Stock payable otherwise
             than in cash out of its retained earnings (excluding
             dividends payable in stock for which adjustment is made
             pursuant to the terms of the Registered Securities and
             Bearer Securities); or

                       (ii) the Company shall authorize the granting to
             the holders of its Common Stock of rights or warrants to
             subscribe for or purchase any shares of capital stock of any
             class or of any other rights; or

                       (iii)  of any reclassification of the Common Stock
             of the Company (other than a subdivision or combination of
             its outstanding shares of Common Stock), or of any
             consolidation with, or merger of the Company into, any other
             corporation, or of any merger of another corporation into
             the Company (other than a merger which does not result in
             any reclassification, conversion, exchange or cancellation
             of outstanding shares of Common Stock of the Company), or of
             any sale or transfer of all or substantially all of the
             assets of the Company (which shall not include the sale or
             transfer of any portion of the assets of the Company to any
             corporation which, immediately following such transfer is at
             least 51% owned by the Company, provided that such sale or
             transfer does not result in the reclassification,
             conversion, exchange or cancellation of outstanding shares
             of Common Stock of the Company); or

                       (iv) of the involuntary dissolution, liquidation
             or winding up of the Company; or

                       (v)  the Company proposes to take any other action
             which would require an adjustment of the Conversion Price
             pursuant to the Registered Securities and Bearer Securities;
                                       23PAGE
<PAGE>
             then the Company shall cause to be filed with the Conversion
             Agent and at each office or agency maintained for the
             purpose of conversion of Securities a notice setting forth
             the adjusted Conversion Price and shall cause notice to be
             given as provided in Section 19 except that notice need be
             given once at least 20 days (or 10 days in any case
             specified in clause (i) or (iii) above) prior to the
             applicable record date hereinafter specified, stating (x)
             the date on which a record is to be taken for the purpose of
             such dividend, distribution, rights or warrants or, if a
             record is not to be taken, the date as of which the holders
             of Common Stock of record to be entitled to such dividend,
             distribution, rights or warrants is to be determined, or (y)
             the date on which a reclassification, consolidation, merger,
             sale, transfer, dissolution, liquidation or winding up is
             expected to become effective, and the date as of which it is
             expected that holders of Common Stock of record shall be
             entitled to exchange their shares of Common Stock for the
             securities, cash or other property deliverable upon such
             reclassification, consolidation, merger, sale, transfer,
             dissolution, liquidation or winding up. The failure to give
             notice required by this Section or any defect therein shall
             not affect the legality or validity of any dividend,
             distribution, rights, warrants, reclassification,
             consolidation, merger, sale, transfer, dissolution,
             liquidation or winding up, or the vote on any such action.

                  (h)  The Company shall, at all times, have reserved and
        available, free from preemptive rights, out of its authorized but
        unissued shares of Common Stock, for the purpose of effecting the
        conversion of Securities, the full number of Conversion Shares
        then issuable upon the conversion of all Securities (based on the
        aggregate principal amount of Securities outstanding).

                  (i)  The Company shall file, as soon as practicable
        following the Closing Date, a shelf registration statement with
        the United States Securities and Exchange Commission covering the
        resale of shares of Common Stock issuable upon conversion of the
        Restricted Securities ("Registrable Securities"); provided that
        any holder of any Restricted Securities shall not sell any shares
        pursuant to such registration statement unless and until it
        provides to the Company such information as the Company may
        reasonably request for use in connection with the identification
        of such holder as a selling stockholder in such registration
        statement, or any prospectus included therein, and no such sale
        shall be made by such holder pursuant to such registration
        statement unless and until such information is included by the
        Company in such registration statement or prospectus.  The
        Company shall in good faith use its best efforts and at its cost
        to cause such registration statement to be declared effective as
        promptly as practicable thereafter and to include in such
        registration statement the information provided by a holder as a
        selling stockholder and shall notify the Fiscal Agent of the
        effectiveness thereof and agrees to use its best efforts to (i)
                                       24PAGE
<PAGE>
        cause all registrations with, and to obtain any approvals by, any
        governmental authority under any Federal or state law of the
        United States that may be required in connection with the
        conversion of the Securities into Common Stock and the resale
        thereof, (ii) maintain the effectiveness of such registrations
        until the earlier of (a) three years from the latest date of
        original issuance of the Securities hereunder, or (b) the date
        that Rule 144(k) under the Securities Act (or successor
        provision) is available for the resale of the shares of Common
        Stock issuable upon conversion of the Restricted Securities (or
        other securities issuable upon conversion of the Securities) and
        (iii) to list the shares of Common Stock required to be issued or
        delivered upon conversion of Securities (or other securities
        issuable upon conversion of the Securities) prior to such issue
        or delivery on such national securities exchange or automated
        over-the-counter trading market where such Common Stock is listed
        or traded at the time of such delivery.  The Company and the
        Guarantor shall, without limitation as to time, jointly and
        severally indemnify and hold harmless, to the fullest extent
        permitted by law, each holder of Registrable Securities, the
        officers, directors and agents and employees of each of them,
        each person who controls such holder (within the meaning of
        Section 15 of the Securities Act or Section 20 of the Securities
        Exchange Act of 1934, as amended) and the officers, directors,
        agents and employees of any such controlling person, from and
        against all losses, claims, damages, liabilities, costs
        (including, without limitation, the costs of preparation and
        attorneys' fees) and expenses (collectively, "Losses"), as
        incurred, arising out of or based upon any untrue or alleged
        untrue statement of a material fact contained in any such
        registration statement, or related prospectus or in any amendment
        or supplement thereto, or arising out of or based upon any
        omission or alleged omission to state therein a material fact
        required to be stated therein or necessary to make the statements
        therein not misleading, except insofar as the same are based
        solely upon information, if any, furnished in writing to the
        Company by such holder expressly for use therein; provided, that
        the Company and the Guarantor shall not be liable to any holder
        of Registrable Securities to the extent that any such Losses
        arise out of or are based upon an untrue statement or alleged
        untrue statement or omission or alleged omission made in any
        preliminary prospectus if either (A)(i) such holder failed to
        send or deliver a copy of the final prospectus with or prior to
        the delivery of written confirmation of the sale by such holder
        of a Registrable Security to the person asserting the claim from
        which such Losses arise and (ii) the prospectus would have
        completely corrected such untrue statement or alleged untrue
        statement or such omission or alleged omission; or (B)(i) such
        untrue statement or alleged untrue statement, omission or alleged
        omission is completely corrected in an amendment or supplement to
        the prospectus and (ii) having previously been furnished by or on
        behalf of the Company with copies of the prospectus as so amended
        or supplemented, such holder thereafter fails to deliver such
        prospectus as so amended or supplemented, prior to or
                                       25PAGE
<PAGE>
        concurrently with the sale of a Registrable Security to the
        person asserting the claim from which such Losses arise.
        Promptly after receipt by an indemnified party under this
        Paragraph (i) of notice of any claim or the commencement of any
        action, the indemnified party shall, if a claim in respect
        thereof is to be made against the Company or the Guarantor under
        this Paragraph (i) notify the Company or the Guarantor, as the
        case may be, in writing of the claim or the commencement of that
        action; provided, however, that the failure to notify the Company
        or the Guarantor, as the case may be, shall not relieve the
        Company or the Guarantor, as the case may be, from any liability
        which it may have to an indemnified party otherwise than under
        this Paragraph (i).  If any such claim or action shall be brought
        against an indemnified party, and it shall notify the Company or
        the Guarantor thereof, the Company or the Guarantor, as the case
        may be, shall be entitled to participate therein and, to the
        extent that the Company or the Guarantor, as the case may be,
        wishes, to assume the defense thereof with counsel reasonably
        satisfactory to the indemnified party.  After notice from the
        Company or the Guarantor, as the case may be, to the indemnified
        party of its election to assume the defense of such claim or
        action, the Company or the Guarantor, as the case may be, shall
        not be liable to the indemnified party under this Paragraph (i)
        for any legal or other expenses subsequently incurred by the
        indemnified party in connection with the defense thereof;
        provided, however, if the defendants in any such action include
        both an indemnified party and the Company or the Guarantor and
        the indemnified party shall have reasonably concluded that there
        may be legal defenses available to it and for other indemnified
        parties that are different from or additional to those available
        to the Company or the Guarantor, as the case may be, the
        indemnified party or parties under this Paragraph (i) shall have
        the right to employ not more than one counsel to represent them
        and, in that event, the reasonable fees and expenses of not more
        than one such separate counsel shall be paid by the Company and
        the Guarantor.  Neither the Company nor the Guarantor shall be
        liable for any settlement effected without its written consent of
        any claim or action.

                  (j)  The Company covenants that all shares of Common
        Stock which may be issued or delivered upon conversion of
        Securities (or other securities issuable upon conversion of the
        Securities) will upon issuance be fully paid and nonassessable
        and, except as provided in Section 13 hereof, the Company will
        pay all stamp, excise or similar taxes or duties, liens and
        charges with respect to the issue thereof.

                  (k)  All converted Securities shall be held by the
        Company, and may, at any time, be delivered to the Fiscal Agent
        for cancellation, which shall hold or dispose of the same in
        accordance with its policy for disposal of canceled securities or
        as otherwise directed by the Company.  Converted Securities shall
        not be transferred.  The Conversion Agent shall give the Company
        prompt notice of all Securities which have been converted, and if
                                       26PAGE
<PAGE>
        the Fiscal Agent is not also the Conversion Agent, the Company
        will promptly give, or cause to be given, written notice to the
        Fiscal Agent of the serial numbers of all Securities which have
        been converted.

                  (1)  In case of any consolidation with, or merger of
        the Company into, any other corporation, or in case of any merger
        of another corporation into the Company (other than a merger
        which does not result in any reclassification, conversion,
        exchange or cancellation of outstanding shares of Common Stock of
        the Company), or in case of any sale or transfer of all or
        substantially all of the assets of the Company (which shall not
        include the sale or transfer of any portion of the assets of the
        Company to any corporation which, immediately following such
        transfer is at least 51% owned by the Company, provided that such
        sale or transfer does not result in the reclassification,
        conversion, exchange or cancellation of outstanding shares of
        Common Stock of the Company), the corporation formed by such
        consolidation or resulting from such merger, or which acquires
        such assets, as the case may be, shall execute and deliver to the
        Fiscal Agent an amendment to the Fiscal Agency Agreement
        providing that the holder of each Registered Security and Bearer
        Security shall have the right during the period such Security
        shall be convertible as specified in the Registered Securities
        and Bearer Securities to convert such Security only into the kind
        and amount of securities, cash and other property receivable upon
        such consolidation, merger, sale or transfer by a holder of the
        number of shares of Common Stock of the Company into which such
        Security might have been converted immediately prior to such
        consolidation, merger, sale or transfer, assuming, if such
        consolidation, merger, sale or transfer is prior to the period
        such Security shall be convertible as specified in the Registered
        Securities and Bearer Securities, that the Securities were
        convertible at such time at the initial Conversion Price as
        adjusted pursuant to the terms of the Registered Securities and
        Bearer Securities.  Such amendment shall provide for adjustments
        which, for events subsequent to the effective date of such
        amendment, shall be as nearly equivalent as may be practicable to
        the adjustments provided for in the Registered Securities and the
        Bearer Securities.  The above provisions of this Section shall
        similarly apply to successive consolidations, mergers, sales or
        transfers.

                  (m)  Subject to Section 11(j) hereof, neither the
        Fiscal Agent nor the Conversion Agent or conversion agency
        appointed by the Company shall at any time be under any duty or
        responsibility to any holder of Securities to determine whether
        any facts exist which may require any adjustment of the
        Conversion Price, or with respect to the nature or extent of any
        such adjustment when made, or with respect to the method
        employed, or herein or in the Registered Securities and Bearer
        Securities provided to be employed, in making the same.  Neither
        the Fiscal Agent nor the Conversion Agent or conversion agency
        appointed by the Company shall be accountable with respect to the
                                       27PAGE
<PAGE>
        validity or value (or the kind or amount) of any shares of Common
        Stock or of any securities or property which may at any time be
        issued or delivered upon the conversion of any Security; and
        neither the Fiscal Agent nor the Conversion Agent or conversion
        agency appointed by the Company makes any representation with
        respect thereto.  Neither the Fiscal Agent nor the Conversion
        Agent or conversion agency appointed by the Company shall be
        responsible for any acts or omissions of the Company including
        without limitation any failure of the Company to issue, transfer
        or deliver any certificates representing shares of Common Stock
        or other securities or property or to make any cash payment upon
        the delivery of any Security for the purpose of conversion or to
        comply with any of the covenants contained in this Section 7.

                  (n)  Any Common Stock issued upon conversion of a
        Restricted Security ("Restricted Common Stock") at any time prior
        to the date which is three years (or the then applicable holding
        period under Rule 144(k) under the Securities Act (or successor
        provision)) after the date of original issuance of such
        Restricted Security and the last date on which the Company or any
        affiliate of the Company was the owner thereof (or any
        predecessor),  and when a registration statement in respect of
        such Common Stock is not effective under the Securities Act,
        shall be subject to the restrictions on transfer set forth in
        Section 3 hereof to the same extent as such Restricted Securities
        which were so converted.  All shares of Restricted Common Stock
        shall bear the legend and transfer requirements set forth in
        Section 3(f) hereof, with such modifications thereto as the
        Company shall deem appropriate.

             8.   Surrendered Securities.

             All Securities, together with any coupons appertaining
        thereto, surrendered for payment, redemption, retirement,
        transfer or exchange and all coupons paid through the application
        of interest installments and all Securities purchased by the
        Company or any subsidiary shall be delivered to the Fiscal Agent.
        In any such case the Fiscal Agent shall cancel all Securities and
        coupons not previously canceled and destroy all such Securities
        and coupons so delivered and shall furnish to the Company and the
        Guarantor a certificate with respect to such destruction.  Such
        certificate shall state, in the case of destruction of the
        Regulation S Global Security, that all certificates of the
        Euroclear Operator or Cedel as to beneficial ownership required
        by Section 4 hereof have been duly presented by the Euroclear
        Operator or Cedel.

             9.   Mutilated, Destroyed, Stolen or Lost Securities.

             The Fiscal Agent is hereby authorized, in accordance with
        the provisions of the Securities and this Section, from time to
        time to authenticate and deliver Securities in exchange for or in
        lieu of Securities that become mutilated, destroyed, stolen or
        lost, upon receipt of indemnity and such other documents or proof
                                       28PAGE
<PAGE>
        as may be required in form and substance satisfactory to the
        Fiscal Agent, the Company and the Guarantor.  Every Security
        authenticated and delivered in exchange for or in lieu of any
        such Security shall have endorsed thereon a Guarantee and shall
        be considered obligations of the Company and the Guarantor and
        shall carry all rights to interest accrued and unpaid and to
        accrue which were carried by such Security, and notwithstanding
        anything to the contrary herein contained, any new Bearer
        Security shall have attached thereto such coupons that neither
        gain nor loss in interest shall result from such exchange or
        substitution.

             10.  Signatures.

                  (a)  Securities shall be executed on behalf of the
        Company by its President, its Secretary, any Vice President or
        its Treasurer, any of whose signatures may be manual or in
        facsimile, and any coupons appertaining thereto shall be executed
        on behalf of the Company by the facsimile signature of its
        President, its Secretary, any Vice President or its Treasurer.
        Any signature in facsimile may be imprinted or otherwise
        reproduced on the Securities.  The Company may adopt and use the
        signature or facsimile signature of any person who shall be a
        President, Secretary, Vice President or Treasurer at the time of
        the execution of the Securities, notwithstanding the fact that at
        the time the Securities shall be authenticated and delivered, or
        disposed of, such person shall have ceased to have held such
        office by virtue of which such person so executed such security.

                  (b)  The Guarantees shall be executed on behalf of the
        Guarantor by its President, any Vice President, or its Treasurer,
        manually or in facsimile, and a facsimile of its corporate seal
        shall be impressed, imprinted or engraved thereon and shall be
        attested by its Secretary or one of its Assistant Secretaries,
        whose signature may be manual or in facsimile, prior to the
        authentication of the Securities on which they are endorsed.  Any
        signature in facsimile may be imprinted or otherwise reproduced
        on the Guarantees.  The Guarantor may adopt and use the signature
        or facsimile signature of any person who shall be any such
        officer of the Guarantor at the time of the execution of the
        Guarantee, notwithstanding the fact that at the time the
        Securities shall be authenticated and delivered, or disposed of,
        such person shall have ceased to be such officer of the
        Guarantor.

             11.  Agreements Concerning Agents.

             Each of the Agents accepts its obligations herein and in the
        Securities, upon the terms and conditions hereof and thereof,
        including the following, to all of which the Company and the
        Guarantor agree and to all of which the rights hereunder of the
        holders from time to time of the Securities and coupons shall be
        subject:
                                       29PAGE
<PAGE>
                  (a)  Each of the Agents shall be entitled to reasonable
             compensation for all services rendered by such Agent, as
             separately agreed by the Company and the Agent, and the
             Company and the Guarantor agree promptly to pay such
             compensation and to reimburse each of the Agents for the
             reasonable out-of-pocket expenses (including, but not
             limited to, counsel fees) incurred by such Agent in
             connection with the services rendered by it hereunder.  The
             Company and the Guarantor also agree to indemnify each of
             the Agents and each other paying agency and conversion
             agency of the Company for, and to hold it harmless against,
             any loss, liability or expense (including the costs and
             expenses of defending against any claim of liability)
             incurred without negligence or bad faith on the part of such
             Agent or other paying agency and conversion agency of the
             Company hereunder.  The obligations of the Company and the
             Guarantor under this clause (a) shall survive payment of the
             Securities or the resignation or removal of any Agent or
             paying agency or conversion agency.

                  (b)  In acting under this Agreement and in connection
             with the Securities, each of the Agents and each other
             paying agency and conversion agency of the Company is acting
             solely as agent of the Company, and does not assume any
             obligation, or relationship of agency or trust, for or with
             any of the owners or holders of the Securities or coupons,
             except that all funds held by the Paying Agent or any other
             paying agency of the Company for payment of principal of,
             premium, if any, or interest on (or Additional Amounts, if
             any, on) the Securities shall be held in trust but need not
             be segregated from other funds except as required by law and
             as set forth herein and in the Securities, and shall be
             applied as set forth herein and in the Securities; provided,
             however, that monies paid by the Company or the Guarantor to
             the Paying Agent or any other paying agency of the Company
             for the payment of principal of or interest on (or
             Additional Amounts, if any, on) Securities remaining
             unclaimed at the end of two years after such principal or
             interest (or Additional Amounts, if any) shall have become
             due and payable shall be repaid to the Company or the
             Guarantor, as provided and in the manner set forth in the
             Securities, whereupon the aforesaid trust shall terminate
             and all liability of the Paying Agent or such other paying
             agency or the Company with respect thereto shall cease.

                  (c)  Each of the Agents and each other paying agency
             and conversion agency of the Company may consult with one or
             more counsel satisfactory to it (including counsel to the
             Company or the Guarantor), and the written opinion of such
             counsel shall be full and complete authorization and
             protection in respect of any action taken, omitted or
             suffered by it hereunder in good faith and in accordance
             with the opinion of such counsel.

                  (d)  Each of the Agents and each other paying agency
             and conversion agency of the Company shall be protected and
             shall incur no liability for or in respect of any action
             taken, omitted or suffered by it in reliance upon any
             Security, Guarantee or coupon, notice, direction, consent,
             certificate, affidavit, statement or other paper or document
             believed in good faith by such Agent or such other paying
             agency and conversion agency of the Company to be genuine
             and to have been signed by the property parties.

                  (e)  Each of the Agents and each other paying agency
             and conversion agency of the Company, its officers,
             directors and employees may become the owner of, or acquire
             any interest in, any Securities or coupons, with the same
             rights that it or they would have if it were not an Agent or
             such other paying agency of the Company hereunder, and may
             engage or be interested in any financial or other
             transaction with the Company, the Guarantor and their
             affiliates and may act on, or as depositary, trustee or
             agent for, any committee or body of holders of Securities or
             other obligations of the Company or the Guarantor, as freely
             as if it were not an Agent or a paying agency or conversion
             agency of the Company hereunder.

                  (f)  Neither the Paying Agent nor any other paying
             agency of the Company shall be under any liability for
             interest on any monies at any time received by it pursuant
             to any of the provisions of this Agreement or of the
             Securities.

                  (g)  The recitals contained herein and in the
             Securities (except in the Fiscal Agent's certificates of
             authentication), shall be taken as the statements of the
             Company or the Guarantor, as the case may be, and the Agents
             assume no responsibility for the correctness of the same.
             None of the Agents makes any representation as to the
             validity or sufficiency of this Agreement or the Securities
             or the coupons or the Guarantees, except for such Agent's
             due authorization to execute this Agreement.  Neither the
             Agents nor any other paying agency or conversion agency of
             the Company shall be accountable for the use or application
             by the Company of the proceeds of any Securities
             authenticated and delivered by the Fiscal Agent in
             conformity with the provisions of this Agreement.

                  (h)  The Agents and each other paying agency and
             conversion agency of the Company shall be obligated to
             perform such duties and only such duties as are herein and
             in the Securities specifically set forth and no implied
             duties or obligations shall be read into this Agreement or
             the Securities against the Agents or any other paying agency
             of the Company.  The Agents shall not be under any
             obligation to take any action hereunder which may tend to
             involve them in any expense or liability, the payment of
                                       31PAGE

             which, within a reasonable time, is not, in their reasonable
             opinion, assured to them.

                  (i)  Unless herein or in the Securities otherwise
             specifically provided, any order, certificate, notice,
             request, direction, or other communication, from the Company
             or the Guarantor made by or given by it under any provision
             of this Agreement shall be sufficient if signed by the
             President, the Secretary, any Vice President or the
             Treasurer of the Company or the Guarantor, as the case may
             be.

                  (j)  Anything in this Agreement to the contrary
             notwithstanding, none of the Agents shall incur any
             liability hereunder, except as a result of negligence or bad
             faith attributable to it or its officers or employees, and
             shall incur no liability for the negligence or bad faith of
             its agents appointed by it with due care; provided that the
             Agent shall notify the Company and the Guarantor of the
             appointment of any such agents.

                  (k)  The Agents shall not be liable for any loss caused
             by events beyond the reasonable control of the Agents,
             including any malfunction, interruption of or error in the
             transmission of information caused by any machines or
             systems or interruption of communication facilities,
             abnormal operating conditions or acts of God.  The Agents
             shall have no liability whatsoever for any consequential,
             special, indirect or speculative losses or damages.

             12.  Offices, Resignation, Successors, Etc. of Agents,
        Paying, Conversion and Transfer Agencies.

                  (a)  The Company agrees that, until none of the
        Securities and coupons are outstanding or until monies for the

                  (b)  Each of the Agents may at any time resign as such
        Agent by giving written notice to the Company and to the
        Guarantor of such intention on its part, specifying the date on
        which its desired resignation shall become effective; provided,
        however, that such date shall not be less than 90 days after
        receipt of such notice by the Company and the Guarantor unless
        the Company and the Guarantor agree to accept less notice.  Each
        of the Agents hereunder may be removed at any time by the filing
        with it of any instrument in writing signed on behalf of the
        Company and the Guarantor and specifying such removal and the
        date when it is intended to become effective.  Such resignation
        or removal shall take effect upon the date of the appointment by
        the Company and the Guarantor, as hereinafter provided, of a
        successor Fiscal Agent, Conversion Agent or Paying Agent, as the
        case may be, and the acceptance of such appointment by such
        successor Agent.  Upon its resignation or removal, each of the
        Agents shall be entitled to the payment by the Company and the
        Guarantor of its compensation for the services rendered hereunder
        and to the reimbursement of all reasonable out-of-pocket expenses
        incurred in connection with the services rendered hereunder by
        such Agent.

                  (c)  In case at any time any of the Agents shall
        resign, or shall be removed, or shall be incapable of acting, or
        shall file a voluntary petition as a debtor under Chapter 7 or 11
        of Title 11 of the United States Code or have an order for relief
        entered against it as a debtor under Chapter 7 or 11 of Title 11
        of the United States Code or make an assignment for the benefit
        of its creditors or consent to the appointment of a receiver of
        all or any substantial part of its property, or shall admit in
        writing its inability to pay or meet its debts as they mature, or
        if an order of any court shall be entered approving any petition
        filed by or against the Fiscal Agent under any legislation
        similar to the provisions of Title 11 of the United States Code
        or against any of the Agents under the provisions of any
        legislation similar to the provisions of Title 11 of the United
        States Code, or if a receiver of it or of all or any substantial
        part of its property shall be appointed, or if any public officer
        shall take charge or control of it or of its property or affairs,
        for the purpose of rehabilitation, conservation or liquidation, a
        successor Agent, qualified as aforesaid, shall be appointed by
        the Company and the Guarantor by an instrument in writing.  Upon
        the appointment as aforesaid of a successor Agent and acceptance
        by it of such appointment, the Agent so superseded shall cease to
        be such Agent hereunder.  If no successor Agent shall have been
        so appointed by the Company and the Guarantor and shall have
        accepted appointment as hereinafter provided, any holder of a
        Security, on behalf of itself and all others similarly situated,
        or any Agent may petition any court of competent jurisdiction for
        the appointment of a successor Agent and shall promptly notify
        the Company and the Guarantor of such action.

                  (d)  Any successor Fiscal Agent, Conversion Agent,
        Transfer Agent or Paying Agent appointed hereunder shall execute,
                                       33PAGE
<PAGE>
        acknowledge and deliver to its predecessor and to the Company and
        the Guarantor an instrument accepting such appointment hereunder,
        and thereupon such successor Agent, without any further act, deed
        or conveyance, shall become vested with all the authority,
        rights, powers, trusts, immunities, duties and obligations of
        such predecessor with like effect as if originally named as such
        Agent hereunder, and such predecessor, upon payment of its
        charges and disbursements then unpaid, shall thereupon become
        obligated to transfer, deliver and pay over, and such successor
        Agent shall be entitled to receive, all monies, securities or
        other property on deposit with or held by such predecessor, as
        such Agent hereunder.

                  (e)  Any corporation or bank into which any of the
        Agents hereunder may be merged or converted, or any corporation
        or bank with which such Agent may be consolidated, or any
        corporation or bank resulting from any merger, conversion or
        consolidation to which such Agent shall be a party, or any
        corporation or bank to which such Agent shall sell or otherwise
        transfer all or substantially all the assets and business of such
        Agent, or any corporation to which the Fiscal Agent shall sell or
        otherwise transfer all or substantially all of its corporate
        trust business, provided that it shall be qualified as aforesaid,
        shall be the successor to such Agent under this Agreement without
        the execution or filing of any document or any further act on the
        part of any of the parties hereto.

                  (f)  So long as there shall be a Fiscal Agent and
        Paying Agent hereunder, the Company shall maintain agencies (i)
        where Registered Securities (but not Bearer Securities or
        coupons) may be presented for surrender for payment (and for the
        payment of Additional Amounts on the Registered Securities, if
        any) and where Securities may be surrendered for conversion in
        the Borough of Manhattan, New York City, and (ii) where Bearer
        Securities and coupons may be surrendered for payment (and for
        the payment of Additional Amounts (pursuant to Section 2 of the
        Bearer Securities) on Bearer Securities, if any) and where Bearer
        Securities may be surrendered for conversion in at least one city
        in Western Europe, which shall be Luxembourg if the Securities
        are listed on the Luxembourg Stock Exchange and so long as listed
        thereon.  The Company now intends to maintain additional agencies
        (subject to applicable laws and regulations) where Bearer
        Securities may be surrendered for payment (and for the payment of
        Additional Amounts (pursuant to Section 2 of the Bearer
        Securities) on Bearer Securities, if any), where Registered
        Securities may be surrendered for payment and where Securities
        may be surrendered for conversion in London, England and, if the
        Securities are listed on the Luxembourg Stock Exchange and so
        long as listed thereon, Luxembourg, and during such period to
        keep the Agents advised of the names and locations of such
        agencies.  Unless the Company shall otherwise notify each of the
        Agents in writing, the sole such paying agencies and conversion
        agencies shall be the agencies specified in the Securities.  The
        Company authorizes the Paying Agent to pay to or to the order of
                                       34PAGE

        the payment of the principal of, premium, if any, and interest on

        Securities and Bearer Securities, if any, on) the Securities.
        Except as otherwise arranged by the Company, the Fiscal Agent
        shall arrange for the payment of the compensation of such paying
        agencies for their services as such, and the Company and the
        Guarantor shall pay to the Fiscal Agent from time to time
        sufficient funds to make such payments.

                  (g)  So long as there shall be a Fiscal Agent, Paying

        Luxembourg Stock Exchange and so long as listed thereon, where

        Securities or for Registered Securities.  Consistent with
        applicable laws and regulations, including the provisions of the
        federal income tax laws of the United States, such agencies may
        be the same agencies as or different agencies from those
        maintained by the Company pursuant to Section 12(f).

             The Company hereby appoints, subject to the listing of the
        Securities on the Luxembourg Stock Exchange, Banque

        transfer, exchange and registration of transfer or exchange of
        Registered Securities shall be made by the Fiscal Agent in New
        York City.

             13.  Taxes.

             The Company will pay all stamp taxes and other similar
        duties, if any, that may be imposed by the United States of
        America or the United Kingdom, or any state or political
        subdivision thereof or taxing authority therein, with respect to
        the execution or delivery of this Agreement, or the issuance of
        the Regulation S Global Security or the Guarantees, or the
        exchange from time to time of the Regulation S Global Security
        for Registered Securities and Bearer Securities, or with respect
        to the issue or delivery of shares of Common Stock on conversion

        of any transfer involved in the issue or delivery of shares of
        Common Stock in a name other than that of the holder of the
        Security or Securities to be converted, and no such issue or
        delivery shall be made unless and until the person requesting
        such issue has paid to the Company the amount of any such tax or
        duty or has established to the satisfaction of the Company that
        such tax or duty has been paid; and further provided that the
        Company shall not be required to pay any tax or duty that may be
                                       35PAGE

        payable in respect of any accrued interest paid in connection
        with the conversion of the Securities.

             14.  Meetings and Votes of Holders.

                  (a)  A meeting of holders of Securities may be called
        at any time and from time to time pursuant to this Section for
        any of the following purposes: (i) to give any notice to the
        Company, to the Guarantor or to the Fiscal Agent, or to give any
        directions to the Fiscal Agent, or to consent to the waiving of
        any default hereunder or under the Registered Securities and
        Bearer Securities and its consequences, or to take any other
        action authorized to be taken by holders of Securities pursuant
        to Section 9 of the Registered Securities and Bearer Securities;
        or (ii) to take any other action authorized to be taken by or on
        behalf of the holders of any specified aggregate principal amount
        of the Securities under any other provision of this Agreement,
        the Registered Securities and Bearer Securities or under
        applicable law.

                  (b)  Meetings of holders of Securities may be held at
        such place or places in New York City or London as the Fiscal
        Agent or, in case of its failure to act, the Company, the
        Guarantor or the holders calling the meeting shall from time to
        time determine.

                  (c)  The Fiscal Agent may at any time call a meeting of
        holders of Securities to be held at such time and at such place
        in any of the locations designated in Section 14(b) hereof as the
        Fiscal Agent shall determine.  Notice of every meeting of holders
        shall be made as specified in Section 19 hereof, except that such
        notice shall set forth the time and the place of such meeting, in
        general terms the action proposed to be taken at such meeting and
        a general description of regulations applicable to such meeting,
        and shall be published at least three times in the publications
        specified in such Section 19, the first publication to be not
        less than 21 nor more than 180 days prior to the date fixed for
        the meeting.

                  (d)  In case at any time the Company, the Guarantor or
        the holders of at least 25% in aggregate principal amount of the
        Securities shall have requested the Fiscal Agent to call a
        meeting of the holders, by written request setting forth in
        reasonable detail the action proposed to be taken at the meeting,
        and the Fiscal Agent shall not have given the first notice of
        such meeting within 21 days after receipt of such request or
        shall not thereafter proceed to cause the meeting to be held as
        provided herein, then the Company, the Guarantor or the holders
        of Securities in the amount above specified may determine the
        time and the place in either of the locations designated in
        Section 14(b) hereof for such meeting and may call such meeting
        to take any action authorized in Section 14(a) hereof by giving
        notice thereof as provided in Section 14(c) hereof.

                  (e)  To be entitled to vote at any meeting of holders
        of Securities, a person shall be (i) a holder of one or more
        Securities, or (ii) a person appointed by an instrument in
        writing as proxy for a holder or holders of Securities by such
        holder or holders, which proxy need not be a holder of
        Securities.  The only persons who shall be entitled to be present
        or to speak at any meeting of holders shall be the persons
        entitled to vote at such meeting and their counsel and any
        representatives of the Fiscal Agent and its counsel and any
        representatives of the Company and its counsel and any
        representatives of the Guarantor and its counsel.

                  (f)  The persons entitled to vote a majority in
        principal amount of the outstanding Securities shall constitute a
        quorum for the transaction of all business specified in Section
        14(a) hereof. No business shall be transacted in the absence of a
        quorum unless a quorum is represented when the meeting is called
        to order.  In the absence of a quorum within 30 minutes of the
        time appointed for any such meeting, the meeting shall, if
        convened at the request of the holders of Securities (as provided
        in Section 14(d) hereof), be dissolved.  In any other case the
        meeting shall be adjourned for a period of not less than 10 days
        as determined by the chairman of the meeting prior to the
        adjournment of such adjourned meeting.  Notice of the reconvening
        of any adjourned meeting shall be given as provided in Section
        14(c) hereof except that such notice need be published only once
        but must be given not less than five days prior to the date on
        which the meeting is scheduled to be reconvened.  Subject to the
        foregoing, at the reconvening of any meeting adjourned for a lack
        of a quorum the persons entitled to vote 25% in principal amount
        of the Securities outstanding shall constitute a quorum for the
        taking of any action set forth in the notice of the original
        meeting.  Notice of the reconvening of an adjourned meeting shall
        state expressly the percentage of the aggregate principal amount
        of the Securities that shall constitute a quorum.  At a meeting
        or an adjourned meeting duly reconvened and at which a quorum is
        present as aforesaid, any resolution and all matters (except as
        limited by Section 9 of the Registered Securities and Bearer
        Securities) shall be effectively passed and decided if passed or
        decided by the persons entitled to vote a majority in principal
        amount of the Securities represented and voting at such meeting,
        provided that such amount shall be not less than 25% in principal
        amount of the Securities outstanding.  Any holder of a Security
        who has executed an instrument in writing appointing a person as
        his proxy shall be deemed to be present for the purposes of
        determining a quorum and be deemed to have voted; provided,
        however, that such holder shall be considered as present or
        voting only with respect to the matters covered by such
        instrument in writing.  Any resolution passed or decision taken
        at any meeting of the holders of Securities duly held in
        accordance with this Section 14 shall be binding on all the
        holders of Securities whether or not present or represented at
        the meeting.

                  (g)  Notwithstanding any other provision of this
        Agreement, the Fiscal Agent may make such reasonable regulations
        as it may deem advisable for any meeting of holders of Securities
        in regard to proof of the holding of Securities and of the
        appointment of proxies and in regard to the appointment and
        duties of inspectors of votes, the submission and examination of
        proxies, certificates and other evidence of the right to vote,
        and such other matters concerning the conduct of the meeting as
        it shall deem appropriate.  Except as otherwise permitted or
        required by any such regulations, the holding of Bearer
        Securities shall be proved by the production of the Bearer
        Securities or by a certificate executed, as depositary, by, and
        the appointment of any proxy shall be proved by having the
        signature of the person executing the proxy witnessed or
        guaranteed by, in each case, any trust company, bank or banker
        satisfactory to the Fiscal Agent.  Such regulations may provide
        that written instruments appointing proxies, regular on their
        face, may be presumed valid and genuine without the proof
        specified herein or other proof.  The holding of Registered
        Securities shall be proved by the registry books maintained in
        accordance with Section 2(d) hereof or by a certificate or
        certificates of the Fiscal Agent in its capacity as Company's
        agent for the maintenance of such books.

                  (h)  The Fiscal Agent shall, by an instrument in
        writing, appoint a temporary chairperson and a temporary
        secretary of the meeting, unless the meeting shall have been
        called by the Company, the Guarantor or by the holders of
        Securities or the Fiscal Agent at the request of the Company, the
        Guarantor or the holders of Securities as provided in Section
        14(d) hereof and in the Securities, in which case the Company,
        the Guarantor or the holders calling the meeting, as the case may
        be, shall in like manner appoint a temporary chairperson and a
        temporary secretary.  A permanent chairperson and a permanent
        secretary of the meeting shall be elected by vote of the holders
        of a majority in principal amount of the Securities represented
        at the meeting and entitled to vote.

                  (i)  At any meeting each holder or proxy shall be
        entitled to one vote for each U.S. $1,000 principal amount of
        Securities held or represented by him; provided, however, that no
        vote shall be cast or counted at any meeting in respect of any
        Securities challenged as not outstanding and ruled by the
        chairperson of the meeting to be not outstanding.  The
        chairperson of the meeting shall have no right to vote, except as
        a holder or proxy.

                  (j)  Any meeting of holders of Securities duly called
        pursuant to Section 14(c) or 14(d) hereof at which a quorum is
        present may be adjourned from time to time by vote of the holders
        (or proxies for the holders) of a majority in principal amount of
        the Securities represented at the meeting and entitled to vote;
        and the meeting may be held as so adjourned without further
        notice.

                  (k)  The vote upon any resolution submitted to any
        meeting of holders of Securities shall be by written ballots on
        which shall be subscribed the signatures of the holders of
        Securities or of their representatives by proxy and the serial
        number or numbers of the Securities held or represented by them.
        The permanent chairperson of the meeting shall appoint two
        inspectors of votes who shall count all votes cast at the meeting
        for or against any resolution and who shall make and file with
        the secretary of the meeting their verified written reports in
        triplicate of all votes cast at the meeting.  A record, at least
        in triplicate, of the proceedings of each meeting of holders of
        Securities shall be prepared by the secretary of the meeting and
        there shall be attached to said record the original reports of
        the inspectors of votes on any vote by ballot taken thereat and
        affidavits by one or more persons having knowledge of the facts
        setting forth a copy of the notice of the meeting and showing
        that said notice was published as provided in Section 14(c) or
        14(d) hereof and, if applicable, Section 14(f) hereof.  Each copy
        shall be signed and verified by the affidavits of the permanent
        chairperson and secretary of the meeting, and one such copy shall
        be delivered to the Company, another to the Guarantor and another
        to the Fiscal Agent to be preserved by the Fiscal Agent, the copy
        delivered to the Fiscal Agent to have attached thereto the
        ballots voted at the meeting.  Any record so signed and verified
        shall be conclusive evidence of the matters therein stated.

             15.  Merger, Consolidation or Sale of Assets.

                  (a)  If at any time there shall be a merger,
        consolidation, sale or conveyance of assets or assumption of
        obligations to which any of the covenants contained in Section 6
        of the Registered Securities and Bearer Securities or Section 3
        of the Guarantees, is applicable, then in any such event the
        successor or assuming corporation referred to therein will
        promptly deliver to the Fiscal Agent:

                  (i)  a certificate signed by an executive officer of
        such successor or assuming corporation stating that as of the
        time immediately after the effective date of any such
        transaction, the covenants of the Company or the Guarantor, as
        the case may be, contained in the Registered Securities and
        Bearer Securities or the Guarantees, as applicable, have been
        complied with and the successor or assuming corporation is not in
        default under the provisions of this Agreement or the Securities
        or the Guarantees, as applicable; and

                  (ii) a written opinion of legal counsel (who may be an
        employee of or counsel to the successor or assuming corporation)
        stating that, in such counsel's opinion, such covenants have been
        complied with and that any instrument or instruments executed in
        the performance of such covenants comply with the requirements
        thereof.
                                       39PAGE
<PAGE>
             In case of any such merger, consolidation, sale, conveyance
        or assumption, such successor or assuming corporation shall
        succeed to and be substituted for the Company or the Guarantor,
        as the case may be, with the same effect, subject to (in the case
        of a merger to which the Company is a party) Section 6(b) of the
        Registered Securities and Bearer Securities, as if such successor
        or assuming corporation had been named herein and in the
        Registered Securities and Bearer Securities or the Guarantees, as
        applicable, as the Company or the Guarantor, as the case may be;
        the Company or the Guarantor, as the case may be, shall thereupon
        be relieved of any further obligation or liability hereunder or
        upon the Securities or the Guarantees, as applicable, provided
        that any successor or assuming corporation shall have the right
        to redeem the Securities, pursuant to Section 3(b) of the
        Registered Securities and Bearer Securities, only as a result of
        circumstances which occur subsequent to such merger,
        consolidation, sale, conveyance or assumption and as a result of
        which the Company would have had such right if the Company had
        remained the obligor on the Securities.  The Company or the
        Guarantor, as the case may be, as the predecessor corporation may
        thereupon or at any time thereafter be dissolved, wound up or
        liquidated.  If applicable, such successor or assuming
        corporation thereupon may cause to be signed, and may issue
        either in its own name or in the name of the Company any or all
        of the Securities issuable hereunder which theretofore shall not
        have been executed on behalf of the Company and delivered to the
        Fiscal Agent; and, upon the order of such successor or assuming
        corporation, instead of the Company, and subject to all the
        terms, conditions and limitations in this Agreement prescribed,
        the Fiscal Agent shall authenticate and shall deliver any
        Securities which previously shall have been signed and delivered
        by the officers of the Company to the Fiscal Agent for
        authentication, and any Securities which such successor or
        assuming corporation thereafter shall cause to be signed and
        delivered to the Fiscal Agent for that purpose.  If applicable,
        such successor or assuming corporation may cause to be endorsed
        either in its own name or in the name of the Guarantor,
        Guarantees on any or all of the Securities issuable hereunder
        which theretofore shall not have been so endorsed and delivered
        to the Fiscal Agent.  All the Securities so issued shall in all
        respects have the same legal rank and benefit under this
        Agreement as the Securities theretofore or thereafter issued in
        accordance with the terms of this Agreement as though all of such
        Securities had been issued at the date of the execution hereof.

             In case of any merger, consolidation, sale, conveyance or
        assumption, such changes in phraseology and form (but not in
        substance) may be made in the Securities or the Guarantees
        thereafter to be issued as may be appropriate.

                  (b)  The Fiscal Agent may rely on the documents
        delivered pursuant to this Agreement by any successor or assuming
        corporation pursuant to this Section 15 as conclusive evidence
        that any such merger, consolidation, sale, conveyance or
                                       40PAGE
<PAGE>
        assumption complies with the provisions of this Section and the
        Securities.

             16.  Governing Law.

             THIS AGREEMENT, THE SECURITIES AND ANY COUPONS APPERTAINING
        THERETO AND THE GUARANTEES SHALL BE GOVERNED BY AND CONSTRUED IN
        ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS,
        UNITED STATES OF AMERICA, WITHOUT GIVING EFFECT TO ITS CONFLICTS
        OF LAW RULES.

             17.  Amendments.

             This Agreement may be amended by the parties hereto, and
        certain provisions hereof may be waived, in the manner provided
        in Section 9 of the Registered Securities and Bearer Securities.
        This Agreement may also be amended by the parties hereto, without
        the consent of the holder of any Security, for the purposes set
        forth in Section 9 of the Registered Securities and Bearer
        Securities and for the purpose of curing any ambiguity, or of
        curing, correcting or supplementing any defective provision
        contained herein or in any manner that the parties may mutually
        deem necessary or desirable, and that shall not materially
        adversely affect the interests of the holders of the Securities.

             18.  Agent for Service of Process.

             As long as any of the Securities or coupons appertaining
        thereto remain outstanding, the Company and the Guarantor will at
        all times have an authorized agent in the City of New York, upon
        whom process may be served in any legal action or proceeding
        arising out of or relating to this Agreement or any Security or
        any coupons appertaining thereto or any Guarantee.  Service of
        process upon such agent and written notice of such service mailed
        or delivered to the Company or the Guarantor, as the case may be,
        shall to the extent permitted by law be deemed in every respect
        effective service of process upon the Company or the Guarantor,
        as the case may be, in any such legal action or proceeding.  Each
        of the Company and the Guarantor hereby appoints the Fiscal Agent
        as its agent for such purpose, and covenants and agrees that
        service of process in any legal action or proceeding may be made
        upon it at the office of such agent located at 450 West 33rd
        Street, 15th Floor, New York, New York 10001  (or such other
        address in the City of New York, as may be the principal
        corporate trust office of such agent), unless and until the
        Company or the Guarantor, as the case may be, shall designate
        another agent for such purpose by written notice to the Fiscal
        Agent.  If the Fiscal Agent receives any such service of process,
        it shall promptly notify the Company and the Guarantor of such
        service.

        or at any other address of which any of the foregoing shall have
        notified the others in writing.

             Notices to holders of the Securities shall be given by
        publication on a Business Day in an Authorized Newspaper. For
        purposes of this Agreement, the term "Authorized Newspaper" means
        an English language newspaper, customarily published on each
        business day in morning editions, whether or not it shall be
        published in Saturday, Sunday or holiday editions, such as The
        Wall Street Journal (Eastern edition) in New York City, the
        Financial Times in London and the Luxemburger Wort in Luxembourg.
        If by reason of the temporary or permanent suspension of
        publication of any newspaper or by reason of any other cause it
        shall be impossible to make publication of such notice in an
        Authorized Newspaper as herein provided, then such publication or
        other notice in lieu thereof as shall be made by the Fiscal Agent
        shall constitute sufficient publication of such notice, if such
        publication or other notice shall, so far as may be possible,
        approximate the terms and conditions of the publication in lieu
        of which it is given.  Notices will be mailed by the Fiscal
        Agent, on behalf of and at the expense of the Company, by
        first-class mail to registered holders of Registered Securities
        at their registered address as the same shall appear on the books
        of the Fiscal Agent on the day 15 days prior to such mailing.
        The Fiscal Agent shall promptly furnish to the Company and to
        each other paying agency of the Company a copy of each notice so
        published or mailed.

             20.  Counterparts.

             This Agreement may be executed in separate counterparts, and
        by each party separately in a separate counterpart, each such
        counterpart, when so executed and delivered, to be an original.
        Such counterparts shall together constitute but one and the same
        instrument.

                      (FORM OF FACE OF REGISTERED SECURITY)

             Unless and until it is exchanged in whole or in part for
        Securities in definitive form, this Security may not be
        transferred except as a whole by the Depository to a nominee of
        the Depository or by a nominee of the Depository to the
        Depository or another nominee of the Depository or by the
        Depository or any such nominee to a successor depository or a
        nominee of such successor Depository.  Unless this certificate is
        presented by an authorized representative of The Depository Trust
        Company, a New York corporation (55 Water Street, New York, New
        York) ("DTC"), to the issuer or its agent for registration of
        transfer, exchange or payment, and any certificate issued is
        registered in the name of Cede & Co. or such other name as may be
        requested by an authorized representative of DTC (and any payment
        is made to Cede & Co. or such other entity as may be requested by
        an authorized representative of DTC), ANY TRANSFER, PLEDGE OR
        OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
        WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has
        an interest herein.(1) 

             THIS SECURITY (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED
        UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE

        ACT) IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE
        EXEMPTION THEREFROM.  EACH PURCHASER OF THIS SECURITY  IS HEREBY
        NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE
        PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE
        144A THEREUNDER.  THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE
        HEREOF, REPRESENTS, ACKNOWLEDGES AND AGREES FOR THE BENEFIT OF
        THE COMPANY THAT: (I) IT HAS ACQUIRED A "RESTRICTED" SECURITY
        WHICH HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT; (II) IT
        WILL NOT OFFER, SELL OR OTHERWISE TRANSFER THIS SECURITY PRIOR TO
        THE DATE WHICH IS THREE YEARS (OR THE THEN APPLICABLE HOLDING
        PERIOD UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR SUCCESSOR
        PROVISION)) AFTER THE DATE OF ORIGINAL ISSUANCE HEREOF AND THE
        LAST DATE ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY
        WAS THE OWNER OF SUCH RESTRICTED SECURITIES (OR ANY PREDECESSOR),
        EXCEPT (A) TO THE COMPANY, (B) PURSUANT TO A REGISTRATION
        STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES
        ACT, (C) FOR SO LONG AS THIS SECURITY IS ELIGIBLE FOR RESALE
        PURSUANT TO RULE 144A, TO A PERSON WHO THE SELLER REASONABLY
        BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE

             Thermo TerraTech Inc., a corporation duly incorporated and
        existing under the laws of the State of Delaware (the "Company"),
        for value received, hereby promises to pay to ________________,
        or registered assigns, the principal sum of __________________
        United States Dollars on May 1, 2003 upon presentation and
        surrender hereof and to pay interest thereon, from May 2, 1996 or
        from the most recent Interest Payment Date (as defined below) to
        which interest has been paid or duly provided for, semiannually
        in arrears on May 1 and November 1 in each year (each an
        "Interest Payment Date"), commencing November 1, 1996, at the
        rate of 4-5/8% per annum, until the principal hereof is paid or
        made available for payment.  Interest hereon shall be calculated
        on the basis of a 360-day year comprised of twelve 30-day months.
        The interest so payable, and punctually paid or duly provided
        for, on any Interest Payment Date will, as provided in the Fiscal
        Agency Agreement (as defined on the reverse hereof), be paid to
        the person in whose name this Security is registered at the close
        of business on the Record Date for such interest payment, which
        shall be the April 15 or October 15 (whether or not a Business
        Day (as defined on the reverse hereof)) next preceding such
        Interest Payment Date.  Except as otherwise provided in the
        Fiscal Agency Agreement (as defined on the reverse hereof), any
        such interest not so punctually paid or duly provided for will
        forthwith cease to be payable to the holder on such Record Date
        and may be paid at any time in any lawful manner, all as more
        fully provided in the Fiscal Agency Agreement.  Payment of
        interest on this Security shall be made by United States dollar
        check drawn on a bank in the City of New York and mailed to the
        person entitled thereto at his address as it shall appear in the
        Security Register, or (if arrangements satisfactory to the
        Company and the Fiscal Agent are made) by wire transfer to a
        United States dollar account maintained by the payee with a bank
        in the City of New York; provided, however, that if such mailing
        is not possible and no such application shall have been made,
        payment of interest shall be made at the principal corporate
        trust office of the Fiscal Agent, or such other office or agency
        of the Company as may be designated for such purpose in the City
        of New York, in United States currency.

             Reference is hereby made to the further provisions of this
        Security set forth under Terms and Conditions of the Securities
                                       A-3PAGE

        on the reverse hereof, which further provisions shall for all
        purposes have the same effect as if set forth at this place.

             This Security shall not become valid or enforceable for any
        purpose unless and until the certificate of authentication hereon
        shall have been manually signed by a duly authorized signatory of
        the Fiscal Agent.

             IN WITNESS WHEREOF, the Company has caused this Security to

        signature of a duly authorized officer.

        transfer to a United States dollar account maintained by the
        holder at a bank outside the United States, its territories and
        its possessions.  Interest on this Security shall be paid only at
        an office or agency located outside the United States, its

        on or before maturity, only upon presentation and surrender at

        detriment to the Company.  Notwithstanding the foregoing, payment
        of this Security and coupons may be made at the office of the

              (FORM OF REVERSE OF REGISTERED AND BEARER SECURITIES)

                     Terms and Conditions of the Securities

        1.   General.

                  (a)  This Security is one of a duly authorized issue of
        Securities of the Company designated as its 4-5/8% Convertible
        Subordinated Debentures Due 2003 (herein called the
        "Securities").  The Company, for the benefit of the holders from
        time to time of the Securities, has entered into a Fiscal Agency
        Agreement dated as of May 2, 1996 (the "Fiscal Agency Agreement")
        among the Company, Thermo Electron Corporation, a corporation
        duly organized and existing under the laws of the State of
        Delaware, as Guarantor (the "Guarantor") and Chemical Bank, as
        Fiscal Agent, Paying Agent, Security Registrar and Conversion
        Agent (the "Fiscal Agent"), to which Fiscal Agency Agreement
        reference is hereby made for a statement of the respective
        rights, limitations of rights, duties and immunities thereunder
        of the Company, the Guarantor, the Fiscal Agent, and the holders
        of Securities and any coupons appertaining thereto and of the
        terms upon which the Securities are, and are to be, authenticated
        and delivered.  The holders of the Securities will be entitled to
        the benefits of, be bound by, and be deemed to have notice of,
        all of the provisions of the Fiscal Agency Agreement.  A copy of
        the Fiscal Agency Agreement is on file and may be inspected at
        the office of paying agencies appointed by the Company.

                  (b)  The Securities are issuable as bearer securities
        (the "Bearer Securities"), with interest coupons attached, in the
        denominations of U.S. $1,000 and U.S. $10,000, and as registered
        securities (the "Registered Securities"), without coupons, in
        denominations of U.S. $1,000 and integral multiples thereof.  The
        Registered Securities, and transfers thereof, shall be registered
        as provided in Section 8 hereof and in the Fiscal Agency
        Agreement.  The holder of any Bearer Security or any coupon and
        the registered holder of a Registered Security shall (to the
        fullest extent permitted by applicable law) be treated at all
        times, by all persons and for all purposes as the absolute owner
        of such Security or coupon, as the case may be, regardless of any
        notice of ownership, theft or loss or of any writing thereon.

                  (c)  The Securities are direct and unsecured
        obligations of the Company, subordinated as set forth in Section
        7 hereof.  There are no restrictions herein on other indebtedness
        or securities which may be incurred or issued by the Company.

             2.   Additional Amounts.  The Company will pay to the holder
        of this Security or of any coupon appertaining hereto who is a
        United States Alien (as defined below) such additional amounts
        ("Additional Amounts") as may be necessary in order that every
        net payment of the principal of, premium, if any, and interest on
        this Security,  after withholding for or on account of any
        present or future tax, assessment or governmental charge imposed
                                      A-10PAGE
<PAGE>
        upon or as a result of such payment by the United States or any
        political subdivision or taxing authority thereof or therein,
        will not be less than the amount provided herein or in any coupon
        appertaining hereto to be then due and payable; provided,
        however, that the foregoing obligation to pay Additional Amounts
        shall not apply to any one or more of the following:

                  (a)  any tax, assessment or other governmental charge
        which would not have been so imposed but for (i) the existence of
        any present or former connection between such holder (or between
        a fiduciary, settlor, beneficiary, member or stockholder of, or a
        person holding a power over, such holder, if such holder is an
        estate, trust, partnership or corporation) and the United States,
        including, without limitation, such holder (or such fiduciary,
        settlor, beneficiary, member, stockholder or person holding a
        power) being or having been a citizen or resident or treated as a
        resident thereof or being or having been engaged in a trade or
        business therein or being or having been present therein or
        having or having had a permanent establishment therein, or (ii)
        such holder's present or former status as a personal holding
        company, foreign personal holding company, passive foreign
        investment company, foreign private foundation or other foreign
        tax-exempt entity or controlled foreign corporation for United
        States tax purposes or a corporation which accumulates earnings
        to avoid United States Federal income tax, or (iii) such holder's
        status as a bank extending credit pursuant to a loan agreement
        entered into in the ordinary course of business;

                  (b)  any tax, assessment or other governmental charge
        which would not have been so imposed but for the presentation by
        the holder of this Security or any coupon appertaining hereto for
        payment on a date more than 10 days after the date on which such
        payment became due and payable or on the date on which payment
        thereof is duly provided, whichever occurs later;

                  (c)  any estate, inheritance, gift, sales, transfer or
        personal property tax or any similar tax, assessment or other
        governmental charge;

                  (d)  any tax, assessment or other governmental charge
        which would not have been imposed but for the failure to comply
        with certification, information, documentation or other reporting
        requirements concerning the nationality, residence, identity or
        present or former connection with the United States of the holder
        or beneficial owner of such Security or any related coupon if
        such compliance is required by statute, regulation or ruling of
        the United States or any political subdivision or taxing
        authority thereof as a precondition to relief or exemption from
        such tax, assessment or other governmental charge;

                  (e)  any tax, assessment or other governmental charge
        which is payable otherwise than by deduction or withholding from
        payments of principal of and premium, if any, or interest on this
        Security;
                                      A-11PAGE
<PAGE>
                  (f)  any tax, assessment or other governmental charge
        imposed on interest received by a person holding, actually or
        constructively, 10% or more of the total combined voting power of
        all classes of stock of the Company entitled to vote; or

                  (g)  any tax, assessment or other governmental charge
        required to be withheld by any paying agent from any payment of
        principal of, or premium, if any, or interest on this Security or
        interest on any coupon appertaining thereto if such payment can
        be made without such withholding by any other paying agent; nor
        will Additional Amounts be paid with respect to any payment of
        the principal of, premium, if any, or interest on this Security
        (or cash in lieu of issuance of shares of Common Stock upon
        conversion) to a person other than the sole beneficial owner of
        such payment, or that is a partnership or fiduciary to the extent
        such beneficial owner, member of such partnership or beneficiary
        or settlor with respect to such fiduciary would not have been
        entitled to the payment of Additional Amounts had such beneficial
        owner, member, beneficiary or settlor been the holder of this
        Security or any coupon appertaining hereto.

             The term "United States Alien" means any person who, for
        United States Federal income tax purposes, is a foreign
        corporation, a non-resident alien individual, a foreign
        partnership, or an estate or trust subject to United States
        Federal income tax on net income basis, and the term "United
        States" means the United States of America (including the several
        States and the District of Columbia), its territories, its
        possessions and other areas subject to its jurisdiction.

             Except as specifically provided herein and in the Fiscal
        Agency Agreement, the Company shall not be required to make any
        payment with respect to any tax, assessment or other governmental
        charge imposed by any government or any political subdivision or
        taxing authority thereof or therein.

             Whenever any Additional Amounts are to be paid on the
        Securities, the Company will give notice to the Guarantor, the
        Fiscal Agent, the Paying Agent and any paying agency of the
        Company, all as provided in the Fiscal Agency Agreement.

             3.   Redemption.

                  (a)  The Company, at its option, may redeem the
        Securities, in whole or in part, at any time on or after May 1,
        1998, upon notice as hereinafter prescribed, at a redemption
        price equal to 100% of the principal amount thereof, together
        with accrued interest to the redemption date; provided, however,
        that the Securities may not be so redeemed on or before May 1,
        1999, unless the Closing Price (as defined in Section 4(c)(v) of
        these Terms and Conditions) per share of Common Stock of the
        Company on twenty of the thirty consecutive days on which there
        was such a price ending within five days prior to the initial
                                      A-12PAGE
<PAGE>
        publication of the notice of such redemption equals or exceeds
        140% of the Conversion Price then in effect.  In the event of a
        partial redemption, the Securities to be redeemed will be
        selected by the Fiscal Agent not more than 75 days before the
        date fixed for redemption by such method as the Fiscal Agent
        shall deem fair and appropriate. Provisions of this Security that
        apply to Securities called for redemption also apply to portions
        of Securities called for redemption.  The Fiscal Agent shall
        notify the Company promptly of the Securities or portions of
        Securities to be called for redemption.

                  (b)  If, at any time, the Company shall determine that
        as a result of any change in or amendment to the laws or any
        regulations or rulings of the United States or any political
        subdivision or taxing authority thereof or therein affecting
        taxation, or any amendment to, or change in, an official
        application or interpretation of such laws, regulations or
        rulings, which amendment or change is announced or becomes
        effective on or after April 26, 1996, the Company has or will
        become obligated to pay to the holder of any Security (other than
        the Registered Securities) or coupon Additional Amounts and such
        obligation cannot be avoided by the Company taking reasonable
        measures available to it, then the Company may, at its election
        exercised at any time when such conditions continue to exist,
        redeem such Securities as a whole but not in part, upon notice as
        hereinafter prescribed, at a redemption price equal to 100% of
        the principal amount, together with accrued interest, if any, to
        the date fixed for redemption; provided that no such notice of
        redemption shall be given earlier than 90 days prior to the
        earliest date on which the Company would be obligated to pay such
        Additional Amounts were a payment in respect of such Securities
        then due; and provided  further that, at the time such notice is
        given, such obligations to pay such Additional Amounts remains in
        effect.

             Prior to any redemption of the Securities pursuant to the
        preceding paragraph, the Company shall provide the Fiscal Agent
        with one or more certificates (signed by the President or any
        Vice President and the Treasurer or the Secretary) of the Company
        on which the Fiscal Agent may conclusively rely to the effect
        that the Company is entitled to redeem such Securities pursuant
        to such paragraph and that the conditions precedent to the right
        of the Company to redeem such Securities pursuant to such
        paragraph have occurred and a written opinion of counsel (who may
        be an employee of the Company or the Guarantor) stating that all
        legal conditions precedent to the right of the Company to redeem
        such Securities pursuant to such paragraph have occurred.

                  (c)  Except as set forth in the next succeeding
        paragraph, the Company shall redeem the Bearer Securities as a
        whole but not in part, upon notice as hereinafter prescribed, at
        100% of their principal amount, together with interest accrued to
        the date fixed for redemption, less applicable withholding taxes,
        if any, plus any applicable Additional Amounts payable, in the
                                      A-13PAGE
<PAGE>
        event that the Company determines that payment of principal of,
        premium, if any, or interest on a Bearer Security or a coupon
        appertaining thereto made outside the United States by the
        Company or a paying agent, based on a written opinion of counsel,
        would under any present or future laws or regulations of the
        United States be subject to any certification, identification or
        information reporting requirement with regard to the nationality,
        residence or identity of a beneficial owner of a Bearer Security
        or a coupon appertaining thereto who is a United States Alien
        (other than a requirement (a) that would not be applicable to a
        payment made by the Company or any one of its paying agents (i)
        directly to the beneficial owner or (ii) to a custodian, nominee
        or other agent of the beneficial owner, or (b) that can be
        satisfied by the custodian, nominee or other agent certifying
        that the beneficial owner is a United States Alien, provided,
        however, in each case referred to in clauses (a)(ii) and (b),
        payment by such custodian, nominee or other agent of the
        beneficial owner is not otherwise subject to any such
        requirement).  The Company shall make such determination on the
        basis of a written opinion of counsel and will notify the Fiscal
        Agent thereof in writing as soon as practicable, stating in the
        notice the effective date of such certification, identification,
        or information reporting requirement and the dates within which
        the redemption shall occur, and the Fiscal Agent shall give
        prompt notice thereof to the holders of the Securities in
        accordance with the Fiscal Agency Agreement.  The Company shall
        determine the redemption date by notice to the Fiscal Agent at
        least 75 days before the redemption date, unless shorter notice
        is acceptable to the Fiscal Agent.  Such redemption of the Bearer
        Securities must take place on such date, not later than one year
        after the publication of the initial notice of the Company's
        determination of the existence of such certification,
        identification or information reporting requirement.  The Company
        shall not so redeem the Bearer Securities, however, if the
        Company, based on a written opinion of counsel, determines not
        less than 30 days prior to the date fixed for redemption, that no
        such payment would be subject to any requirement described above,
        in which case the Company shall notify the Fiscal Agent, which
        shall give prompt notice of that determination in accordance with
        the Fiscal Agency Agreement and any earlier redemption notice
        shall thereupon be revoked and of no further effect.

             Notwithstanding the next preceding paragraph, if and so long
        as the certification, identification or information reporting
        requirement referred to in the next preceding paragraph would be
        fully satisfied by payment of United States withholding, backup
        withholding or similar taxes, the Company may elect, prior to
        publication of the notice of redemption and in lieu of redemption
        of the Bearer Securities, to have the provisions of this
        paragraph apply in lieu of the provisions of the next preceding
        paragraph.  In that event, the Company will pay such Additional
        Amounts (without regard to Section 2 hereof) as are necessary in
        order that, following the effective date of such requirements,
        every net payment made outside the United States by the Company
                                      A-14PAGE
<PAGE>
        or a paying agent of the principal of, premium, if any, and
        interest on a Bearer Security or a coupon appertaining thereto to
        a holder who is a United States Alien (without regard to a
        certification, identification or information reporting
        requirement as to the nationality, residence or identity of such
        holder), after deduction for United States withholding, backup
        withholding or similar taxes (other than a tax (i) that would not
        be applicable in the circumstances referred to in the
        parenthetical clause of the first sentence of the next preceding
        paragraph or (ii) are imposed as a result of presentation of such
        Bearer Security or coupon for payment more than 10 days after the
        date on which such payment becomes due and payable or on which
        payment thereof is duly provided for, whichever occurs later),
        will not be less than the amount provided in the Bearer Security
        or the related coupon to be then due and payable.  If the Company
        elects to pay such Additional Amounts and as long as it is
        obligated to pay such Additional Amounts, the Company may
        subsequently redeem the Bearer Securities, at any time, in whole
        but not in part, upon not more than 60 days nor less than 30 days
        notice, given as hereinafter prescribed, at 100% of their
        principal amount, plus accrued interest to date fixed for
        redemption and Additional Amounts, if any.

                  (d)  Each Security is subject to redemption in whole or
        in part (which shall be in a principal amount hereof which is
        U.S. $1,000 or an integral multiple thereof) at the option of the
        holder thereof on any Holder Redemption Date (as defined below)
        at a redemption price equal to 100% of the principal amount
        thereof, together with accrued interest, if a Redemption Event
        shall occur or have occurred.  For purposes hereof a "Redemption
        Event" shall have occurred if the Company's Common Stock (or
        other equity securities into which the Securities are then
        convertible) is neither listed for trading on a United States
        national securities exchange nor approved for trading on an
        established automated over-the-counter trading market in the
        United States.  The "Holder Redemption Date" with respect to any
        Redemption Event shall be the ninetieth day after the later of
        the Exchange Date or the date a Redemption Event has occurred.

             Notwithstanding the fact that a Security or a portion
        thereof is called for redemption by the Company, each holder of a
        Security desiring to exercise the option for redemption set forth
        in this Section 3(d) shall, as a condition to such redemption, on
        or before the close of business on the fifth day prior to the
        Holder Redemption Date, surrender the Security to be redeemed in
        whole or in part together with the redemption notice hereon duly
        executed at the place or places specified in the notice required
        by Section 3(e) and otherwise comply with the provisions of
        Section 3(f).  A holder of a Security who has tendered a
        redemption notice (i) will be entitled to revoke its election by
        delivering a written notice of such revocation together with the
        holder's non-transferable receipt for such Security to the office
        or agency of the Company designated as the place for the payment
        of the Securities to be so redeemed on or before the Holder
                                      A-15PAGE
<PAGE>
        Redemption Date and (ii) will retain the right to convert its
        Securities into shares of Common Stock of the Company to the
        extent set forth in Section 4.

                  (e)  Notice of redemption will be given by publication
        in Authorized Newspapers (as defined in the Fiscal Agency
        Agreement) on a Business Day (as defined in the Fiscal Agency
        Agreement) in New York City and in London and, if the Securities
        are listed on the Luxembourg Stock Exchange and so long as listed
        thereon, in an Authorized Newspaper in Luxembourg, or, if either
        publication in London or Luxembourg is not practical, in an
        Authorized Newspaper in any country in Western Europe, and by
        mail to holders of Registered Securities, all as provided in the
        Fiscal Agency Agreement.  In the case of a redemption in whole at
        the option of the Company, notice will be given once not more
        than 60 nor less than 30 days prior to the date fixed for
        redemption.  In the case of a partial redemption at the option of
        the Company, notice will be given twice, the first such notice to
        be given not more than 75 nor less than 60 days prior to the date
        fixed for redemption and the second such notice to be given not
        more than 60 nor less than 30 days prior to the date fixed for
        redemption.  In the case of a redemption by the Company at the
        option of a holder of a Security pursuant to Section 3(d) hereof,
        notice will be given by the Fiscal Agent setting forth the
        information described below not later than 10 days after the
        later of the Exchange Date or the occurrence of a Redemption
        Event. Neither the failure to give notice nor any defect in any
        notice given to any particular holder of a Security shall affect
        the sufficiency of any notice with respect to other Securities.

             Notices relating to the redemption of Securities whether at
        the option of the Company or the holder hereof shall specify: the
        date fixed for redemption or the Holder Redemption Date, as the
        case may be; the redemption price; the date the conversion
        privilege expires; the place or places of payment; and that
        payment will be made upon presentation and surrender of the
        Securities to be redeemed, together, in the case of a Bearer
        Security, with all appurtenant coupons, if any, maturing
        subsequent to the date fixed for redemption; and that interest
        accrued to the date fixed for redemption (unless the redemption
        date is an interest payment date) will be paid as specified in
        such notice; and that, on and after said date, interest thereon
        will cease to accrue.  In the case of a redemption by the Company
        at the option of the holder of a Security pursuant to Section
        3(d), the notices given by the Fiscal Agent informing a holder of
        such holder's entitlement to redeem shall also specify that a
        holder electing redemption will be entitled to revoke its
        election by delivering a written notice of such revocation,
        together with the holder's non-transferable receipt for such
        Security, to the agency designated by the Company as the place
        for the payment of the Securities to be so redeemed not later
        than the fifth day prior to the Holder Redemption Date.  In the
        case of a redemption in part at the option of the Company,
        notices shall specify the aggregate principal amount of
                                      A-16PAGE
<PAGE>
        Securities to be redeemed and the aggregate principal amount of
        Securities outstanding after such partial redemption.  The first
        notice shall specify the last date on which exchanges or
        transfers of Securities may be made, and the second notice shall
        specify the serial numbers of the Securities and the portions
        thereof called for redemption.  In the case of a redemption in
        whole or in part by the Company, notices shall specify the date
        the conversion privilege expires in accordance with Section 4(a)
        hereof.  Such notices shall also state that the conditions
        precedent, if any, to such redemption have occurred.

                  (f)  If (i) notice of redemption has been given in the
        manner set forth in Section 3(e) hereof with respect to
        Securities to be redeemed at the option of the Company, or (ii)
        notice of redemption has been given by the holder of a Security
        to be redeemed pursuant to Section 3(d) hereof, the Securities so
        to be redeemed shall become due and payable on the applicable
        redemption date specified in such notice and upon presentation
        and surrender of the Securities at the place or places specified
        in the notices given by the Company with respect to such
        redemption, together in the case of Bearer Securities with all
        appurtenant coupons, if any, maturing subsequent to the
        redemption date and any related mature defaulted coupons, the
        Securities shall be paid and redeemed by the Company, at the
        places and in the manner and currency herein specified and at the
        redemption price together with accrued interest, if any, to the
        redemption date; provided, however, that interest due in respect
        of coupons maturing on or prior to the redemption date shall be
        payable only upon the presentation and surrender of such coupons
        (at an office or agency located outside of the United States of
        America).  If any Bearer Security surrendered for redemption
        shall not be accompanied by all appurtenant coupons maturing
        after the redemption date and any related mature defaulted
        coupons, such Security may be paid after deducting from the
        amount otherwise payable an amount equal to the face amount of
        all such missing coupons, or the surrender of such missing coupon
        or coupons may be waived by the Company and the Fiscal Agent if
        they are furnished with such security or indemnity as they may
        require to save each of them and each other paying agency of the
        Company harmless.  From and after the redemption date, if monies
        for the redemption of Securities shall have been available at the
        principal corporate trust office of the Fiscal Agent for
        redemption on the redemption date, the Securities shall cease to
        bear interest, the coupons for interest appertaining to Bearer
        Securities maturing subsequent to the redemption date shall be
        void, the only right of the holders of such Securities shall be
        to receive payment of the redemption price together with accrued
        interest to the redemption date.  If monies for the redemption of
        the Securities are not made available by the Company for payment
        until after the redemption date, the Securities shall not cease
        to bear interest until such monies have been so made available.

                  (g)  Accrued interest payable on any Registered
        Security that is redeemed will be payable against surrender of
                                      A-17PAGE
<PAGE>
        such Registered Security in the manner described in this Section
        with respect to payments of principal on Registered Securities,
        except that interest on any Registered Security that is redeemed
        on a date after the close of business on any interest Record Date
        and on or before the next succeeding Interest Payment Date, shall
        be paid to the holder of record of such Registered Security on
        the interest Record Date.

             4.   Conversion.

                  (a)  Subject to and upon compliance with the provisions
        of the Fiscal Agency Agreement, a holder of Securities is
        entitled, at its option, at any time on or after the date that is
        the latest of (i) the Exchange Date, (ii) July 15, 1996 and (iii)
        the date of the effectiveness of the Registration Statement to be
        filed by the Company under the Securities Act relating to the
        Common Stock issuable upon conversion of the Restricted
        Securities (the "Registration Date") and on or before the close
        of business on May 1, 2003, or in the case of a Security or
        portion thereof that is called for redemption by the Company, or
        the holder thereof elects to have such Security or portion
        thereof redeemed by the Company pursuant to Section 3(d) hereof,
        then in respect of such Security or such portion thereof until
        and including, but (unless the Company and the Guarantor default
        in making the payment due upon redemption) not after, the close
        of business on the 15th day next preceding the date fixed for
        redemption (or if such date is not a business day, as described
        in Section 11 hereof in New York City, then the next succeeding
        business day), to convert such Security (or any portion of the
        principal amount thereof which is U.S. $1,000 or an integral
        multiple thereof), at the principal amount thereof, or of such
        portion, into fully paid and nonassessable shares ("Conversion
        Shares") (calculated as to each conversion to the nearest 1/1000
        of a share) of common stock, par value $.10 per share of the
        Company ("Common Stock"), at a Conversion Price equal to U.S.
        $15.90 aggregate principal amount of Securities for each
        Conversion Share (the "Conversion Price") (or at the current
        adjusted Conversion Price if an adjustment has been made as
        provided herein) by surrender of the Security, or in the case of
        a Security submitted for redemption pursuant to Section 3(d)
        hereof, satisfactory evidence of such submission, together with
        (i) if a Bearer Security, all unmatured coupons and any matured
        coupons in default appertaining thereto, and if a Registered
        Security (if so required by the Company or the Fiscal Agent),
        instruments of transfer in form satisfactory to the Company and
        the Fiscal Agent, duly executed by the registered holder or by
        his duly authorized attorney, and (ii) the conversion notice
        hereon duly executed (x) at the principal corporate trust office
        of the Fiscal Agent, or at such other office or agency of the
        Company as may be designated by it for such purpose in New York
        City, or (y) subject to any laws or regulations applicable
        thereto and subject to the right of the Company to terminate the
        appointment of any such conversion agency, at Chemical Bank,
        Chemical Bank House, 125 London Wall, London EC2Y 5AJ, England,
                                      A-18PAGE

        and if the Securities are listed on the Luxembourg Stock Exchange
        and so long as listed thereon, Banque Internationale a
        Luxembourg, S.A., 69, Route d'Esch, L-1470 Luxembourg, or at such
        other offices or agencies as the Company may designate.

                  (b)  In the case of a conversion after the close of
        business on a Record Date next preceding any interest payment
        date and before the opening of business on such interest payment
        date, the holder of record of a Registered Security at such
        Record Date is to receive an installment of interest on the
        interest payment date.  No payment or adjustment shall be made
        upon any conversion for dividends on the Common Stock delivered
        on conversion.  Except as set forth in the first sentence of this
        subsection (b), accrued interest from the immediately preceding
        interest payment date until the date of conversion (together with
        any Additional Amounts, if any, thereon) will be paid to the
        holder within five business days after presentment for conversion
        on account of any interest accrued on the Securities surrendered
        for conversion, except that interest on Registered Securities
        surrendered for conversion after the close of business on a
        Record Date and before the opening of business on the next
        succeeding interest payment date shall be paid in an amount equal
        to the interest payable on such interest payment date on the
        principal amount being surrendered for conversion.  No fractions
        of shares or scrip representing fractions of shares will be
        issued or delivered on conversion, but instead of any fractional
        interest the Company shall pay a cash adjustment as provided in
        the Fiscal Agency Agreement.  Such conversion shall be so
        affected by the Company, except payment of accrued interest
        (together with Additional Amounts, if any, thereon) which will be
        paid by the Paying Agent.

                  (c)  (i)  In case at any time the Company shall pay or
        make a dividend or other distribution on any class of capital
        stock of the Company in shares of Common Stock, the Conversion
        Price in effect at the opening of business on the day following
        the date fixed for the determination of stockholders entitled to
        receive such dividend or other distribution shall be reduced so
        that the same shall equal the price determined by multiplying
        such Conversion Price by a fraction of which the numerator shall
        be the number of shares of Common Stock outstanding at the close
        of business on the date fixed for such determination and the
        denominator shall be the sum of such number of shares and the
        total number of shares of Common Stock constituting such dividend
        or other distribution, such adjustment to become effective
        immediately after the opening of business on the day following
        the date fixed for such determination.

                       (ii) In the case at any time the Company shall (A)
        subdivide its outstanding shares of Common Stock, (B) combine its
        outstanding shares of Common Stock into a smaller number of
        shares, or (C) issue by reclassification of its shares of Common
        Stock (including any such reclassification in connection with a
        consolidation or merger in which the Company is the continuing
                                      A-19PAGE
<PAGE>
        corporation) any shares of capital stock, the Conversion Price in
        effect at the effective date of such subdivision, combination or
        reclassification shall be proportionately adjusted so that the
        holder of any Security surrendered for conversion after such time
        shall be entitled to receive the aggregate number and kind of
        shares which, if such Security had been converted immediately
        prior to such time, the holder would have owned upon such
        conversion and been entitled to receive upon such subdivision,
        combination or reclassification.  Such adjustment shall become
        effective immediately after the effectiveness of such
        subdivision, combination or reclassification.  Such adjustment
        shall be made successively whenever any event listed above shall
        occur.

                       (iii)  In case at any time the Company shall fix a
        record date for the issuance of rights or warrants to all holders
        of its Common Stock entitling them to subscribe for or purchase
        Common Stock at a price per share less than the current market
        price per share of Common Stock (determined as provided in
        paragraph (v) of this subsection (c)) on such record date, the
        Conversion Price in effect at the opening of business on the day
        following such record date shall be reduced so that the same
        shall equal the price determined by multiplying such Conversion
        Price by a fraction of which the numerator shall be the number of
        shares of Common Stock outstanding at the close of business on
        such record date plus the number of shares of Common Stock which
        the aggregate of the offering price of the total number of shares
        so offered for subscription or purchase would purchase at such
        current market price per share of Common Stock and the
        denominator shall be the number of shares of Common Stock
        outstanding at the close of business on such record date plus the
        number of shares so offered for subscription or purchase, such
        reduction to become effective immediately after the opening of
        business on the day following such record date.  Such reduction
        shall be made successively whenever such a record date is fixed;
        and in the event that such rights or warrants are not so issued,
        the Conversion Price shall again be adjusted to be the Conversion
        Price which would then be in effect if such record date had not
        been fixed.

                       (iv) In case at any time the Company shall fix a
        record date for the making of a distribution, by dividend or
        otherwise, to all holders of its shares if Common Stock, of
        evidences of its indebtedness or assets (including securities,
        but excluding any dividend or distribution referred to in
        paragraph (i) of this subsection (c), any rights or warrants
        referred to in paragraph (iii) of this subsection (c), and any
        dividend or distribution paid in cash out of the retained
        earnings of the Company), then in each such case the Conversion
        Price in effect after such record date shall be determined by
        multiplying the Conversion Price in effect immediately prior to
        such record date by a fraction, of which numerator shall be the
        total number of outstanding shares of Common Stock multiplied by
        the current market price per share of Common Stock (determined as
                                      A-20PAGE
<PAGE>
        provided in paragraph (v) of this subsection (c)) on such record
        date, less the fair market value (as determined by the Board of
        Directors of the Company, whose determination shall be conclusive
        and described in a statement filed with the Fiscal Agent) of the
        portion of the assets or evidences of indebtedness so to be
        distributed, and of which denominator shall be the total number
        of outstanding shares of Common Stock multiplied by such current
        market price per share of Common Stock.  Such adjustment shall be
        made successively whenever such a record date is fixed; and in
        the event that such distribution is not so made, the Conversion
        Price shall again be adjusted to be the Conversion Price which
        would then be in effect if such record date has not been fixed.

                       (v)  For the purpose of any computation under
        paragraphs (iii) and (iv) of this subsection (c), the current
        market price per share of Common Stock on any date shall be
        deemed to be the average of the Closing Prices (as defined below)
        for the 15 consecutive trading days upon which the principal
        trading market for the Common Stock is open and selected by the
        Company commencing not less than 20 nor more than 30 days before
        the day in question.  The "Closing Price" for any day shall be
        the last reported sales prices regular way or, in case no such
        reported sale takes place on such day, the average of the
        reported closing bid and asked prices regular way, in either case
        on the American Stock Exchange or, if the Common Stock is not or
        admitted to trading on such exchange, on the principal national
        securities exchange on which the Common Stock is listed or
        admitted to trading or, if not listed or admitted to trading on
        any national securities exchange, the closing sale price quoted
        on the Nasdaq National Market, or if not so quoted, as determined
        by the Company.

                       (vi) The Company may make such adjustments in the
        Conversion Price, in addition to those required by paragraphs
        (i), (ii) and, (iii) selected by the Company of this section, as
        it considers to be advisable in order that any event treated for
        United States Federal income tax purposes as a dividend of stock
        or stock rights shall not be taxable to the recipients.

                       (vii)  No adjustment in the Conversion Price shall
        be required unless such adjustment would require an increase or
        decrease of at least U.S. $.25 in such Conversion Price;
        provided, however, that any adjustment which by reason of this
        paragraph (vii) is not required to be made shall be carried
        forward and taken into account in any subsequent adjustment.  All
        calculations under this subsection (c) shall be made to the
        nearest cent or to the nearest 1/1000 of a share, as the case may
        be.

                  (d)  Whenever the Conversion Price is adjusted and in
        the event of certain other corporate actions, as herein provided,
        the Company shall give notice, all as provided in the Fiscal
        Agency Agreement.

                  (e)  The Company shall file, as soon as practicable
        following the Closing Date, a shelf registration statement with
        the United States Securities and Exchange Commission covering the
        resale of the shares of Common Stock issuable upon conversion of
        the Restricted Securities ("Registrable Securities"); provided
        that any holder of any Restricted Securities or Registrable
        Securities shall not sell any shares pursuant to such
        registration statement unless and until it provides to the
        Company such information as the Company may reasonably request
        for use in connection with the identification of such holder as a
        selling stockholder in such registration statement, or any
        prospectus included therein, and no such sale shall be made by
        such holder pursuant to such registration statement unless and
        until such information is included by the Company in such
        registration statement or prospectus.  The Company shall in good
        faith use its best efforts and at its cost to cause such
        registration statement to be declared effective as promptly as
        practicable thereafter and to include in such registration
        statement the information provided by a holder as a selling
        stockholder and shall notify the Fiscal Agent of the
        effectiveness thereof and agrees to use its best efforts to (i)
        cause all registrations with, and to obtain any approvals by, any
        governmental authority under any Federal or state law of the
        United States that may be required in connection with the
        conversion of the Securities into Common Stock and the resale
        thereof, (ii) maintain the effectiveness of such registrations
        until the earlier of (a) three years from the date of the Fiscal
        Agency Agreement, or (b) the date that Rule 144(k) under the
        Securities Act is available for the resale of the shares of
        Common Stock issuable upon conversion of the Restricted
        Securities (or other securities issuable upon conversion of the
        Securities) and (iii) to list the shares of Common Stock required
        to be issued or delivered upon conversion of Securities (or other
        securities issuable upon conversion of the Securities) prior to
        such issue or delivery on such national securities exchange or
        automated over-the-counter trading market where such Common Stock
        is listed or traded at the time of such delivery.  The Company
        and the Guarantor shall, without limitation as to time, indemnify
        and hold harmless, to the fullest extent permitted by law, each
        holder of Registrable Securities, the officers, directors and
        agents and employees of each of them, each person who controls
        such holder (within the meaning of Section 15 of the Securities
        Act or Section 20 of the Securities Exchange Act of 1934, as
        amended) and the officers, directors, agents and employees of any
        such controlling person, from and against all losses, claims,
        damages, liabilities, costs (including, without limitation, the
        costs of preparation and attorneys' fees) and expenses
        (collectively, "Losses"), as incurred, arising out of or based
        upon any untrue or alleged untrue statement of a material fact
        contained in any such registration statement, or related
        prospectus or in any amendment or supplement thereto, or arising
        out of or based upon any omission or alleged omission to state
        therein a material fact required to be stated therein or
        necessary to make the statements therein not misleading, except
                                      A-22PAGE
<PAGE>
        insofar as the same are based solely upon information, if any,
        furnished in writing to the Company by such holder expressly for
        use therein; provided, that the Company and the Guarantor shall
        not be liable to any holder of Registrable Securities to the
        extent that any such Losses arise out of or are based upon an
        untrue statement or alleged untrue statement or omission or
        alleged omission made in any preliminary prospectus if either
        (a)(i) such holder failed to send or deliver as required a copy
        of the final prospectus with or prior to the delivery of written
        confirmation of the sale by such holder of a Registrable Security
        to the person asserting the claim from which such Losses arise
        and (ii) the prospectus would have completely corrected such
        untrue statement or alleged untrue statement or such omission or
        alleged omission; or (b)(i) such untrue statement or alleged
        untrue statement, omission or alleged omission is completely
        corrected in an amendment or supplement to the prospectus and
        (ii) having previously been furnished by or on behalf of the
        Company with copies of the prospectus as so amended or
        supplemented, such holder thereafter fails to deliver as required
        such prospectus as so amended or supplemented, prior to or
        concurrently with the sale of a Registrable Security to the
        person asserting the claim from which such Losses arise. Promptly
        after receipt by an indemnified party under this Paragraph (e) of
        notice of any claim or the commencement of any action, the
        indemnified party shall, if a claim in respect thereof is to be
        made against the Company or the Guarantor under this Paragraph
        (e) notify the Company or the Guarantor, as the case may be, in
        writing of the claim or the commencement of that action;
        provided, however, that the failure to notify the Company or the
        Guarantor, as the case may be, shall not relieve the Company or
        the Guarantor, as the case may be, from any liability which it
        may have to an indemnified party otherwise than under this
        Paragraph (e).  If any such claim or action shall be brought
        against an indemnified party, and it shall notify the Company or
        the Guarantor thereof, the Company or the Guarantor, as the case
        may be, shall be entitled to participate therein and, to the
        extent that the Company or the Guarantor, as the case may be,
        wishes, to assume the defense thereof with counsel reasonably
        satisfactory to the indemnified party.  After notice from the
        Company or the Guarantor, as the case may be, to the indemnified
        party of its election to assume the defense of such claim or
        action, the Company or the Guarantor, as the case may be, shall
        not be liable to the indemnified party under this Paragraph (e)
        for any legal or other expenses subsequently incurred by the
        indemnified party in connection with the defense thereof;
        provided, however, if the defendants in any such action include
        both an indemnified party and the Company or the Guarantor and
        the indemnified party shall have reasonably concluded that there
        may be legal defenses available to it and for other indemnified
        parties that are different from or additional to those available
        to the Company or the Guarantor, as the case may be, the
        indemnified party or parties under this Paragraph (e) shall have
        the right to employ not more than one counsel to represent them
        and, in that event, the reasonable fees and expenses of not more
                                      A-23PAGE
<PAGE>
        than one such separate counsel shall be paid by the Company and
        the Guarantor.  Neither the Company nor the Guarantor shall be
        liable for any settlement effected without its written consent of
        any claim or action.

                  (f)  The Company shall, at all times, have reserved and
        available, free from preemptive rights, out of its authorized but
        unissued shares of Common Stock, for the purpose of effecting the
        conversion of Securities, the full number of shares of Common
        Stock then issuable upon the conversion of all Securities (based
        on the aggregate principal amount of Securities outstanding).
        The Company covenants that all shares of Common Stock which may
        be issued or delivered upon conversion of Securities will upon
        issuance be fully paid and nonassessable.

                  (g)  In case of any consolidation with, or merger of
        the Company into, any other corporation, or in case of any merger
        of another corporation into the Company (other than a merger
        which does not result in any reclassification, conversion,
        exchange or cancellation of outstanding shares of Common Stock of
        the Company), or in case of any sale or transfer of all or
        substantially all of the assets of the Company (which shall not
        include the sale or transfer of any portion of the assets of the
        Company to any corporation which, immediately following such
        transfer is at least 51% owned by the Company, provided that such
        sale or transfer does not result in the reclassification,
        conversion, exchange or cancellation of outstanding shares of
        Common Stock of the Company), the corporation formed by such
        consolidation or resulting from such merger or which acquires
        such assets, as the case may be, shall execute and deliver to the
        Fiscal Agent an amendment to the Fiscal Agency Agreement
        providing that the holder of each Security shall have the right
        during the period such Security shall be convertible as specified
        in section (a) hereof to convert such Security only into the kind
        and amount of securities, cash and other property receivable upon
        such consolidation, merger, sale or transfer by a holder of the
        number of shares of Common Stock of the Company into which such
        Security might have been converted immediately prior to such
        consolidation, merger, sale or transfer assuming, if such
        consolidation, merger, sale or transfer is prior to the period
        such Security shall be convertible as specified in subsection (a)
        hereof, that the Securities were convertible at such time at the
        initial Conversion Price as adjusted from April 26, 1996 to such
        time pursuant to paragraphs (i), (ii), (iii), (iv) and (vi) of
        subsection (c) hereof.  Such amendment shall provide for
        adjustments which, for events subsequent to the effective date of
        such amendment, shall be as nearly equivalent as may be
        practicable to the adjustments provided for herein.  The above
        provisions of this subsection shall similarly apply to successive
        consolidations, mergers, sales or transfers.

             5.   Events of Default.  In the event that any of the
        following ("Events of Default") shall occur and be continuing:
                                      A-24PAGE
<PAGE>
                  (a)  the Company shall fail to pay when due the
        principal of, or premium, if any, on any of the Securities
        whether at maturity or upon redemption or otherwise; or

                  (b)  the Company shall fail to pay any installment of
        interest or any required payment of any Additional Amounts (as
        described in Section 2 hereof) on any of the Securities for a
        period of 10 days after the date when due; or

                  (c)  the Company shall fail duly to perform or observe
        any other term, covenant or agreement contained in any of the
        Securities or in the Fiscal Agency Agreement or the Guarantor
        shall fail to perform or observe any term, covenant or  agreement
        contained in a Guarantee endorsed on any of the Securities or in
        the Fiscal Agency Agreement, for a period of 60 days after the
        date on which written notice of such failure, requiring the
        Company or the Guarantor, as the case may be, to remedy the same,
        shall first have been given to the Company and the Fiscal Agent
        by the holders of at least 25% in aggregate principal amount of
        the Securities at the time outstanding; provided, however, that
        in the event the Company or the Guarantor shall within the
        aforesaid period of 60 days commence legal action in a court of
        competent jurisdiction seeking a determination that the Company
        or the Guarantor, as the case may be, had not failed duly to
        perform or observe the term or terms, covenant or covenants or
        agreement or agreements specified in the aforesaid notice, such
        failure shall not be an Event of Default unless the same
        continues for a period of 10 days after the date of any final
        determination to the effect that the Company or the Guarantor had
        failed to duly perform or observe one or more of such terms,
        covenants or agreements; or

                  (d)  a court having jurisdiction in the premises shall
        enter a decree or order for relief in respect of the Company or
        the Guarantor in an involuntary case or proceeding under any
        applicable bankruptcy, insolvency, reorganization or other
        similar law now or hereafter in effect, or appointing a receiver,
        liquidator, assignee, custodian, trustee, sequestrator (or
        similar official) of the Company or the Guarantor or for any
        substantial part of the property of either of them or ordering
        the winding-up or liquidation of the affairs of either of them
        and such decree or order shall remain unstayed and in effect for
        a period of 20 consecutive days; or

                  (e)  the Company or the Guarantor shall commence a
        voluntary case or proceeding under any applicable bankruptcy,
        insolvency, reorganization or other similar law now or hereafter
        in effect, or shall consent to the entry of an order for relief
        in an involuntary case under any such law, or shall consent to
        the appointment of or taking possession by a receiver,
        liquidator, assignee, trustee, custodian, sequestrator (or
        similar official) of the Company or the Guarantor, as the case
        may be, or for any substantial part of its property, or shall
        make any general assignment for the benefit of creditors, or
                                      A-25PAGE
<PAGE>
        shall admit in writing its inability to pay its debts as they
        become due or shall take any corporate action in furtherance of
        any of the foregoing; or

                  (f)  an event of default, as defined in any indenture
        or instrument evidencing or under which the Company shall have at
        least $15,000,000 outstanding (or its equivalent in another
        currency), in aggregate principal amount of indebtedness for
        borrowed money, shall happen and be continuing and such default
        shall involve the failure to pay the principal of such
        indebtedness (or any part thereof), when due and payable after
        the expiration of any applicable grace period with respect
        thereto, or such indebtedness shall have been accelerated so the
        same shall be or become due and payable prior to the date on
        which the same would otherwise have become due and payable, and
        failure to pay shall not have been cured by the Company within 20
        days after such failure or such acceleration shall not be
        rescinded or annulled within 20 days after notice thereof shall
        have first been given to the Company; provided that if such event
        of default under such indenture or instrument shall be remedied
        or cured by the Company or waived by the holders of such
        indebtedness, then the Event of Default hereunder by reason
        thereof shall be deemed likewise to have been thereupon remedied,
        cured or waived without further action upon the part of any of
        the holders of Securities; then the holder of this Security may,
        at such holder's option, declare the principal of this Security
        and the interest accrued hereon (and Additional Amounts under
        Section 2 hereof, if any, thereon) to be due and payable
        immediately by written notice to the Company, the Guarantor and
        the Fiscal Agent, and if any such Event of Default shall continue
        at the time of receipt of such written notice, the principal of
        this Security and the interest accrued hereon (and Additional
        Amounts, if any, hereon) shall become immediately due and
        payable, subject to the proviso of subsection (c) of this Section
        5. Upon payment of such amount of principal, premium, if any, and
        interest (and Additional Amounts pursuant to Section 2 hereof, if
        any), all of the Company's obligations in respect of payment of
        principal of, premium, if any, and interest on (and Additional
        Amounts, if any, on) this Security shall terminate.  Interest on
        overdue principal, premium, if any, and interest (and Additional
        Amounts, if any) shall accrue from the date on which such
        principal, premium, if any, and interest (and Additional Amounts,
        if any) were due and payable to the date such principal, premium,
        if any, and interest (and Additional Amounts, if any) are paid or
        duly provided for, at the rate borne by the Securities (to the
        extent payment of such interest shall be legally enforceable).
        Any acceleration of this Security pursuant to this Section 5
        shall not affect the subordination provisions of Section 7
        hereof.

             If an Event of Default, as defined in this Section 5, with
        respect to the Securities, or an event which would, with the
        passing of time or the giving of notice, or both, be an Event of
        Default, shall occur and be continuing, the Company or the
                                      A-26PAGE
<PAGE>
        Guarantor, as the case may be, shall within five Business Days of
        becoming aware thereof notify the Company or the Guarantor, as
        the case may be, and the Fiscal Agent in writing of such Event of
        Default, and the Fiscal Agent shall thereupon promptly notify all
        of the holders of the Securities of such Event of Default.

             6.   Merger, Consolidation, Sale, Conveyance or Assumption.

                  (a)  The Company will not merge or consolidate with, or
        sell or convey all or substantially all of its assets to, any
        other corporation, unless (i) either (A) the Company shall be the
        surviving corporation in the case of a merger, (B) the assets
        sold or conveyed shall be owned by a corporation which,
        immediately following such sale or conveyance, is at least 51%
        owned by the Company, provided that such sale or conveyance does
        not result in the reclassification, conversion, exchange or
        cancellation of outstanding shares of Common Stock of the
        Company, or (C) (I) the surviving, resulting or transferee
        corporation shall expressly assume the due and punctual payment
        (including Additional Amounts pursuant to Section 2 hereof, if
        any) of all the Securities, according to their tenor, and the due
        and punctual performance of all of the covenants and obligations
        of the Company under the Securities, the coupons and the Fiscal
        Agency Agreement, by supplemental agreement reasonably
        satisfactory to the Fiscal Agent and (II) the Fiscal Agent shall
        have received the documentation required in the context by the
        Fiscal Agency Agreement, (ii) the surviving, resulting or
        transferee corporation, if not organized and validly existing
        under the laws of the United States, shall expressly agree to
        make payments under the Securities free of any deduction or
        withholding for any and all then existing or future withholding
        taxes, levies, imposts and charges whatsoever imposed by or for
        the account of the jurisdiction where such successor corporation
        is generally subject to taxation (or any political subdivision or
        taxing authority thereof or therein) in a manner equivalent to
        that set forth herein, subject to the exceptions contained in
        such forms of the Securities, and (iii) the Company or such
        successor corporation, as the case may be, shall not, immediately
        after such merger, consolidation, sale or conveyance, be in
        default in the performance of any covenants or obligations of the
        Company under the Securities or the Fiscal Agency Agreement.

                  (b)  Upon any merger, consolidation, sale, conveyance
        or assumption as provided in Section 6(a), the successor or
        assuming corporation shall succeed to and be substituted for, and
        may exercise every right and power of and be subject to all the
        obligations of, the Company under the Securities and Fiscal
        Agency Agreement, with the same effect as if such successor or
        assuming corporation had been named as the Company therein and
        herein and the Company shall be released from its liability as
        obligor under the Securities and Fiscal Agency Agreement;
        provided that any successor or assuming corporation shall have
        the right to redeem the Securities pursuant to Section 3(b)
        hereof only as a result of circumstances which occur subsequent
                                      A-27PAGE
<PAGE>
        to such merger, consolidation, sale, conveyance or assumption and
        as a result of which the Company would have had such right if the
        Company had remained the obligor on the Securities.

             7.   Agreement of Subordination of Securities.

                  (a)  The Company, for itself, its successors and
        assigns, covenants and agrees, and each holder of Securities and
        coupons by his acceptance thereof, likewise covenants and agrees,
        that the payment of the principal of, premium, if any, and
        interest and Additional Amounts (pursuant to Section 2 hereof) on
        each and all of the Securities and coupons is hereby expressly
        subordinated, to the extent and in the manner hereinafter set
        forth, in right of payment to the prior payment in full of all
        Senior Indebtedness of the Company (as defined below).

             "Senior Indebtedness of the Company" or "Senior
        Indebtedness" shall mean the principal of, premium, if any, and
        interest on and all other amounts due on or with respect to the
        following whether outstanding at the date of execution of the
        Fiscal Agency Agreement or thereafter incurred or created:

                  (i)  indebtedness of the Company for money borrowed by
        the Company (excluding the Securities, but including, without
        limitation, purchase money obligations), whether or not evidenced
        by debentures, bonds, notes or other corporate debt securities or
        similar instruments issued by the Company; provided, however,
        that Senior Indebtedness shall not include the Company's 6 1/2%
        Convertible Subordinated Debentures due 1997 or the Company's
        obligations to the Guarantor under several promissory notes due
        April 1996 through June 1997, the obligations represented by

        hereby in right of payment;

                  (ii) obligations to reimburse any bank or other person
        in respect of amounts paid under letters of credit;

                  (iii)  leases of real property, equipment or other
        assets, which leases are capitalized in the Company's financial
        statements in accordance with generally accepted accounting
        principles;

                  (iv) commitment, standby and other fees due and payable
        to financial institutions with respect to credit facilities
        available to the Company;

                  (v)  obligations of the Company under interest rate and
        currency swaps, floors, caps or other similar arrangements
        intended to hedge interest rates or currency exposure;

                  (vi) indebtedness secured by any mortgage, pledge, lien
        or other encumbrance on property which is owned or held by the
        Company subject to such mortgage, pledge, lien or other
                                      A-28PAGE
<PAGE>
        encumbrance, whether or not the indebtedness secured thereby
        shall have been assumed by the Company;

                  (vii)  obligations of the Company constituting
        guarantees of indebtedness of or joint obligations with another
        or others which would be included in the preceding clauses (i),
        (ii), (iii), (iv), (v) or (vi); and

                  (viii)  modifications, renewals, extensions or
        refundings of any of the indebtedness, leases, fees or
        obligations referred to in the preceding clauses (i), (ii),
        (iii), (iv), (v), (vi) or (vii), or debentures, notes or other
        evidences of indebtedness issued in exchange therefor;

        provided that Senior Indebtedness shall not include any
        particular indebtedness, lease, fee, obligation, modification,
        renewal, extension, refunding or exchanged securities if, under
        the express provisions of the instrument creating or evidencing
        the same, or pursuant to which the same is outstanding, such
        indebtedness, lease, fee or obligation or such modification,
        renewal, extension, refunding or exchanged security is stated to
        be not superior in right to payment to the Securities.

        Indebtedness of the Company, provided that the rights of the
        holders of Senior Indebtedness of the Company are not altered by
        such reorganization or readjustment), shall be received by the
        holders of the Securities before all Senior Indebtedness of the
        Company is paid in full, such payment or distribution shall be

                  (iii)  Upon any distribution of assets of the Company

        or payable thereon, the amount or amounts paid or distributed
        thereon and all other facts pertinent thereto or to this Section.

                  (c)  (i) Upon the maturity of any Senior Indebtedness
        of the Company by lapse of time, acceleration or otherwise, all
        principal thereof (and premium, if any) and interest due thereon,
        including interest thereon accruing after the commencement of any

        Securities or coupons.

                       (ii) Upon the happening of an event of default
        with respect to any Senior Indebtedness of the Company, as
                                      A-30PAGE
<PAGE>
        defined therein or in the instrument under which it is
        outstanding permitting the holders to accelerate the maturity
        thereof, then, unless and until such event of default shall have
        been cured or waived or shall have ceased to exist, no payment
        shall be made by the Company, directly or indirectly, on account
        of the principal of, premium, if any, or interest and Additional
        Amounts (pursuant to Section 2 hereof) on the Securities or
        coupons.

        shall have been applied, pursuant to Section 7(b) or 7(c), to the
        payment of Senior Indebtedness of the Company, then, upon the
        payment in full of all Senior Indebtedness of the Company, the
        holders of the Securities shall be subrogated to any rights of
        any holders of Senior Indebtedness of the Company to receive any
        further payment or distributions applicable to Senior
        Indebtedness of the Company until the principal of, premium, if
        any, and interest and Additional Amounts (pursuant to Section 2
        hereof) on the Securities shall have been paid in full, and such
        payments or distributions received by the holders of the
        Securities and coupons, by reason of such subrogation, of cash,
        securities or other property which otherwise would be paid or
        distributed to the holders of Senior Indebtedness of the Company
        shall, as between the Company and its creditors other than the
        holders of Senior Indebtedness of the Company, on the one hand,
        and the holders of the Securities, on the other hand, be deemed
        to be a payment by the Company on account of Senior Indebtedness
        of the Company and not on account of the Securities.

                  (e)  No present or future holder of any Senior
        Indebtedness of the Company shall be prejudiced in any way in the
        right to enforce the subordination of the Securities by any act
        or failure to act on the part of the Company.  The provisions of
        this Section are solely for the purpose of defining the relative
        rights of the holders of Senior Indebtedness of the Company, on
        the one hand, and the holders of the Securities, on the other
        hand, against the Company and its assets, and nothing contained
        in this Section shall impair, as between the Company and the
        holder of any Security, the obligation of the Company, which is
        unconditional and absolute, to pay to the holder thereof, the
        principal thereof, premium, if any, and interest and Additional
        Amounts (pursuant to Section 2 hereof) thereon as and when the
        same shall become due and payable in accordance with the terms
        thereof, or prevent the holder of any Security, upon default
        hereunder or under such Security, from exercising all rights,
        powers and remedies otherwise provided herein or therein or by
        applicable law, all subject to the rights of the holders of
        Senior Indebtedness of the Company under this Section to receive
        cash, property or securities otherwise payable or deliverable to
        the holders of the Securities and coupons.

                  (f)  Nothing contained in this Section or in any of the
        Securities shall prevent at any time, except under the conditions
                                      A-31PAGE
<PAGE>
        described in Sections 7(b) and (c) hereof or during the pendency
        of any dissolution, winding up, liquidation or reorganization
        proceedings therein referred to, the Company from making payments
        at any time of principal of, premium, if any, or interest or
        Additional Amounts (pursuant to Section 2 hereof) on the
        Securities.  Nothing contained in this Section shall prevent
        conversions of Securities.

             8.   Replacement, Transfer and Exchange of Securities.

                  (a)  In case any Security (including any coupons
        appertaining thereto) shall at any time become mutilated,
        destroyed, stolen or lost and such Security or evidence of the
        loss, theft or destruction thereof (together with the indemnity
        hereinafter referred to and such other documents or proof as may
        be required) shall be delivered to the Fiscal Agent, a new
        Security of like tenor and date with appropriate interest
        coupons, if any, and having the Guarantee endorsed thereon will
        be issued by the Company in exchange for the Security so
        mutilated, or in lieu of the Security so destroyed, stolen or
        lost, but, in the case of a destroyed, stolen or lost Security
        only upon receipt of evidence satisfactory to the Fiscal Agent,
        the Company and the Guarantor that such Security was destroyed,
        stolen or lost, and if required by the Fiscal Agent, the Company
        or the Guarantor, upon receipt also of indemnity satisfactory to
        the Fiscal Agent, the Company and the Guarantor.  All expenses
        and reasonable charges associated with procuring such indemnity
        and with the preparation, authentication and delivery of a new
        Security shall be borne by the owner of the Security so
        mutilated, destroyed, stolen or lost.

                  (b)  As provided in the Fiscal Agency Agreement and
        subject to certain limitations therein set forth, Bearer
        Securities (with all unmatured and matured defaulted coupons
        appertaining thereto) are exchangeable at, subject to applicable
        laws and regulations, the offices of the paying agencies in
        London and, if the Securities are listed on the Luxembourg Stock
        Exchange and so long as listed thereon, Luxembourg or as
        designated by the Company for such purpose pursuant to the Fiscal
        Agency Agreement, for an equal aggregate principal amount of
        Registered Securities in the denominations of $1,000 and integral
        multiples thereof without coupons and/or Bearer Securities of
        authorized denominations, and Registered Securities are
        exchangeable at the Corporate Trust Office of the Fiscal Agent in
        New York City or, subject to applicable laws and regulations, the
        offices of the paying agencies in London and, if the Securities
        are listed on the Luxembourg Stock Exchange and so long as listed
        thereon, Luxembourg or as designated by the Company for such
        purpose pursuant to the Fiscal Agency Agreement, for an equal
        aggregate principal amount of Registered Securities of authorized
        denominations as requested by the holder surrendering the same.
        Registered Securities will not be exchangeable for Bearer
        Securities.  The Company shall not be required (a) to exchange
        Bearer Securities for Registered Securities during the period
                                      A-32PAGE
<PAGE>
        between the close of business on each April 15 and October 15 and
        the opening of business on the next succeeding interest payment
        date or (b) to exchange Bearer Securities for Registered
        Securities, if as a result, the Company or the Guarantor would
        incur adverse consequences under United States Federal income tax
        laws in effect of the time of exchange, or (c) in the event of a
        redemption in part, (i) to register the transfer of Registered
        Securities or to exchange Bearer Securities for Registered
        Securities for a period of 15 days immediately preceding the date
        notice is given identifying the serial numbers of the Securities
        called for such redemption; (ii) to register the transfer or
        exchange of any such Registered Securities, or portion thereof,
        called for redemption; or (iii) to exchange any such Bearer
        Securities called for redemption; provided, however, that a
        Bearer Security called for redemption may be exchanged for a
        Registered Security that is simultaneously surrendered, with
        written instruction for payment on the date fixed for redemption,
        unless the date fixed for redemption is during the period between
        the close of business on each April 15 and October 15 and the
        close of business on the next succeeding interest payment date,
        in which case such exchange may only be made prior to the close
        of business on each April 15 and October 15 immediately preceding
        the date fixed for redemption.  In the event of redemption or
        conversion of a Security in part only, a new Security or
        Securities for the unredeemed or unconverted portion hereof will
        be issued in the name of the holder thereof.

                  (c)  The costs and expenses of effecting any exchange
        or registration of transfer pursuant to the foregoing provisions,
        except for the expenses of delivery by other than regular mail
        (if any) and except, if the Company shall so require, the payment
        of a sum sufficient to cover any tax or other governmental charge
        or insurance charges that may be imposed in relation thereto,
        will be borne by the Company.

                  (d)  The Company has initially appointed as registrar
        and transfer agent the Fiscal Agent acting through the Corporate
        Trust Office in New York.  The Company has also initially
        appointed Banque Internationale a Luxembourg as a transfer agent,
        subject to the listing of the Securities on the Luxembourg Stock
        Exchange.  The Company may at any time terminate the appointment
        of the registrar and transfer agent and appoint additional or
        other registrars and transfer agents or approve any change in an
        office through which the registrar and transfer agent acts;
        provided that, until all of the Securities have been delivered to
        the Fiscal Agent for cancellation, or monies sufficient to pay
        the Securities have been made available for payment and either
        paid or returned to the Company as provided in the Securities,
        the Company will maintain a registrar and transfer agent in the
        City of New York in the United States.

                  (e)  For purposes of the provisions of this Security
        and the Fiscal Agency Agreement, any Security authenticated and
        delivered pursuant to the Fiscal Agency Agreement shall, as of
                                      A-33PAGE

        any date of determination, be deemed to be "outstanding", except
        for:

                       (i)  Securities previously canceled by the Fiscal
        Agent or delivered to the Fiscal Agent for cancellation;

                       (ii) Securities which have been called for
        redemption by the Company in accordance with Section 3 hereof or
        which have become due and payable at maturity or otherwise and
        with respect to which monies sufficient to pay the principal
        thereof and interest thereon (including Additional Amounts, if
        any) shall have been made available to the Fiscal Agent; or

                       (iii)  Securities in lieu of or in substitution
        for which other Securities have been authenticated and delivered
        pursuant to the Fiscal Agency Agreement;

        provided, however, that in determining whether the holders of the
        requisite principal amount of outstanding Securities are present
        at a meeting of holders of Securities for quorum purposes or have
        given any request, demand, authorization, direction, notice,
        consent or waiver hereunder, Securities owned by the Company or
        the Guarantor or any subsidiary thereof shall be disregarded and
        deemed not to be outstanding.

             9.   Modifications and Amendments.

                  (a)  Without the consent of any holders of Securities

        Securities or related coupons; or

                       (vi) to increase the principal amount of
        Securities that may be issued pursuant to the Fiscal Agency

        Agreement or to the Terms and Conditions of the Securities may be
        made, and future compliance with or past default by the Company
        under any of the provisions thereof may be waived, with the
        written consent of the holders of not less than a majority in
        aggregate principal amount of the Securities at the time
        outstanding (excluding for purposes of this calculation the
        aggregate principal amount of Securities held by the Company or

        It shall not be necessary for any act of holders of Securities
        under this Section to approve the particular form of any proposed
        amendment, modification or waiver, but it shall be sufficient if

        other provision of the Fiscal Agency Agreement, under applicable
        law or under these Terms and Conditions.

                  (b)  Meetings of holders of Securities may be held at
        such place or places in New York City or London as the Fiscal
        Agent or, in case of its failure to act, the Company, the
        Guarantor or the holders calling the meeting shall from time to
        time determine.

             The Fiscal Agent may at any time call a meeting of holders
        of the Securities to be held at such time and at such place in
        any of such designated locations as the Fiscal Agent shall
        determine.  Notice of every meeting of holders shall be made as
        specified in the Fiscal Agency Agreement.

             In case at any time the Company, the Guarantor or the
        holders of at least 25% in aggregate principal amount of the
        Securities shall have requested the Fiscal Agent to call a
        meeting of the holders, by written request setting forth in
        reasonable detail the action proposed to be taken at the meeting,
        and the Fiscal Agent shall not have given the first notice of
        such meeting within 21 days after receipt of such request or
        shall not thereafter proceed to cause the meeting to be held as
        provided herein, then the Company , the Guarantor or the holders
        of Securities in the amount above specified may determine the
        time and the place in such designated locations for such meeting
        and may call such meeting to take any action authorized herein by
        giving notice thereof as provided in the Fiscal Agency Agreement.

                  (c)  To be entitled to vote at any meeting of holders
        of Securities, a person shall be (i) a holder of one or more
        Securities, or (ii) a person appointed by an instrument in
        writing as proxy for a holder or holders of Securities by such
        holder or holders, which proxy need not be a holder of
        Securities. The only persons who shall be entitled to be present
        or to speak at any meeting of holders shall be the persons
        entitled to vote at such meeting and their counsel and any
        representatives of the Fiscal Agent and its counsel and any
        representatives of the Company and its counsel and any
        representatives of the Guarantor and its counsel.  The persons
        entitled to vote a majority in principal amount of outstanding
        Securities shall constitute a quorum for the transaction of all
        business specified in subsection (a) hereof.  No business shall
        be transacted in the absence of a quorum unless a quorum is
        represented when the meeting is called to order.  In the absence
        of a quorum within 30 minutes of the time appointed for any such
        meeting, the meeting shall, if convened at the request of the
        holders of Securities, be dissolved.  In any other case the
        meeting shall be adjourned for a period of not less than 10 days
        as determined by the chairman of the meeting prior to the
        adjournment of such adjourned meeting.  Notice of the reconvening
        of any adjourned meeting shall be given as provided in the Fiscal
        Agency Agreement.  Subject to the foregoing, at the reconvening
        of any meeting adjourned for a lack of a quorum the persons
        entitled to vote 25% in principal amount of the Securities
        outstanding shall constitute a quorum for the taking of any
        action set forth in the notice of the original meeting.  Notice
        of the reconvening of an adjourned meeting shall state expressly
        the percentage of the aggregate principal amount of the
        Securities that shall constitute a quorum.  At a meeting or an
        adjourned meeting duly reconvened and at which a quorum is
        present as aforesaid, any resolution and all matters (except as
        limited by Section 9 of these Terms and Conditions) shall be
                                      A-37PAGE
<PAGE>
        effectively passed and decided if passed or decided by the
        persons entitled to vote a majority in principal amount of the
        Securities represented and voting at such meeting, provided that
        such amount shall not be less than 25% in principal amount of the
        Securities outstanding.  Any holder of a Security who has
        executed an instrument in writing appointing a person as his
        proxy shall be deemed to be present for the purposes of
        determining a quorum and be deemed to have voted; provided,
        however, that such holder shall be considered as present or
        voting only with respect to the matters covered by such
        instrument in writing.  Any resolution effectively passed or
        decision taken at any meeting of the holders of Securities duly
        held in accordance with this Section 10 shall be binding on all
        the holders of Securities whether or not present or represented
        at the meeting.

                  (d)  Notwithstanding any other provision of this
        Security, the Fiscal Agent may make such reasonable regulations
        as it may deem advisable for any meeting of holders of Securities
        in regard to proof of the holding of Securities and of the
        appointment of proxies and in regard to the appointment and
        duties of inspectors of votes, the submission and examination of
        proxies, certificates and other evidence of the right to vote,
        and such other matters concerning the conduct of the meeting as
        it shall deem appropriate.  Except as otherwise permitted or
        required by any such regulations, the holding of Bearer
        Securities shall be proved by the production of the Bearer
        Securities or by a certificate executed, as depositary, by, and
        the appointment of any proxy shall be proved by having the
        signature of the person executing the proxy witnessed or
        guaranteed by, in each case, any trust company, bank or banker
        satisfactory to the Fiscal Agent.  Such regulations may provide
        that written instruments appointing proxies, regular on their
        face, may be presumed valid and genuine without the proof
        specified herein or other proof.  The holding of Registered
        Securities shall be proved by the registry books maintained in
        accordance with the Fiscal Agency Agreement or by a certificate
        or certificates of the Fiscal Agent in its capacity as the
        Company's agent for the maintenance of such books.

                  (e)  The Fiscal Agent shall, by an instrument in
        writing, appoint a temporary chairperson and a temporary
        secretary of the meeting, unless the meeting shall have been
        called by the Company, the Guarantor or by the holders of
        Securities as provided herein and in the Fiscal Agency Agreement,
        in which case the Company, the Guarantor or the holders calling
        the meeting, as the case may be, shall in like manner appoint a
        temporary chairperson and a temporary secretary.  A permanent
        chairperson and a permanent secretary of the meeting shall be
        elected by vote of the holders of a majority in principal amount
        of the Securities represented at the meeting and entitled to
        vote.  At any meeting each holder or proxy shall be entitled to
        one vote for each U.S. $1,000 principal amount of Securities held
        or represented by him; provided, however, that no vote shall be
                                      A-38PAGE
<PAGE>
        cast or counted at any meeting in respect of the Securities
        challenged as not outstanding and ruled by the chairperson of the
        meeting to be not outstanding.  The chairperson of the meeting
        shall have no right to vote, except as a holder or proxy.  Any
        meeting of holders of Securities duly called at which a quorum is
        present may be adjourned from time to time by vote of the holders
        (or proxies for the holders) of a majority in principal amount of
        the Securities represented at the meeting and entitled to vote;
        and the meeting may be held as so adjourned without further
        notice.

                  (f)  The vote upon any resolution submitted to any
        meeting of holders of Securities shall be written ballots on
        which shall be subscribed the signatures of the holders of
        Securities or of their representatives by proxy and the serial
        number or numbers of the Securities held or represented by them.
        The permanent chairperson of the meeting shall appoint two
        inspectors of votes who shall count all votes cast at the meeting
        for or against any resolution and who shall make and file with
        the secretary of the meeting their verified written reports in
        triplicate of all votes cast at the meeting.  A record, at least
        in triplicate, of the proceedings of each meeting of holders of
        Securities shall be prepared by the secretary of the meeting and
        there shall be attached to said record the original reports of
        the inspectors of votes on any vote by ballot taken thereat and
        affidavits by one or more persons having knowledge of the facts
        setting forth a copy of the notice of the meeting and showing
        that said notice was published as provided in the Fiscal Agency
        Agreement. Each copy shall be signed and verified by the
        affidavits of the permanent chairperson and secretary of the
        meeting, and one of such copy shall be delivered to the Company,
        another to the Guarantor and another to the Fiscal Agent to be
        preserved by the Fiscal Agent, the copy delivered to the Fiscal
        Agent to have attached thereto by ballots voted at the meeting.
        Any record so signed and verified shall be conclusive evidence of
        the matters therein stated.

             11.  Business Days.  Notwithstanding anything herein or in
        the Fiscal Agency Agreement to the contrary, if any payment of
        interest or premium or principal (or Additional Amounts, if any)
        is due on a day that is not a Business Day, payment shall be made
        on the next succeeding Business Day, with the same effect as if
        made on the day such payment was due, and no interest shall
        accrue for the period after such date.  A "Business Day" is
        defined, with respect to any act to be performed pursuant hereto
        or to the Fiscal Agency Agreement, as any day which is not a
        Saturday, Sunday or a day on which banking institutions in the
        place where such act is to occur are authorized or obligated by
        applicable law, regulation or executive order to close.

             12.  Fiscal and Paying Agent.

                  (a)  In acting under the Fiscal Agency Agreement and in
        connection with the Securities, the Fiscal Agent is acting solely
                                      A-39PAGE

        obligation, or relationship of agency or trust, for or with the
        owner or holder of this Security or any interest coupon
        appertaining hereto, except that funds held by the Fiscal Agent
        for payment on this Security shall be held in trust by it and
        applied as set forth herein, but need not be segregated from
        other funds held by it, except as required by law.  For a
        description of the duties and the immunities and rights of the
        Fiscal Agent under the Fiscal Agency Agreement, reference is made
        to the Fiscal Agency Agreement, and the obligations of the Fiscal
        Agent to the holder hereof are subject to such immunities and
        rights.

                  (b)  Any monies paid by the Company to any paying
        agency for payment of principal of, premium, if any, or interest
        on any Security (including Additional Amounts, if any, in respect
        thereof) and remaining unclaimed for two years after such payment
        has been made shall be repaid to the Company and to the extent
        permitted by law the holder of any Security shall thereafter look
        only to the Company or the Guarantor for any payment thereof as a
        general unsecured obligation thereof and all liability of the
        Fiscal Agent with respect thereto shall cease.

                  (c)  No reference herein to the Fiscal Agency Agreement
        and no provision of this Security or of the Fiscal Agency
        Agreement shall alter or impair the obligation of the Company,
        which is absolute and unconditional, to pay the principal of,
        premium, if any, and interest (and Additional Amounts, as
        described above) on this Security at the times, places and rate,
        and in the coin or currency, herein prescribed or to convert or
        redeem (at the request of a holder) this Security as provided
        herein or in the Fiscal Agency Agreement.

             Title to Bearer Securities and coupons shall pass by
        delivery.  As provided in the Fiscal Agency Agreement and subject
        to certain limitations therein set forth, the transfer of
        Registered Securities is registrable on the Security Register
        upon surrender of a Registered Security for registration of
        transfer at the office or agency of the Company in the City of
        New York,  duly endorsed by, or accompanied by a written
        instrument of transfer in form satisfactory to the Company and
        the Security Registrar duly executed by, the holder thereof or
        his attorney duly authorized in writing, and thereupon one or
        more new Registered Securities, of authorized denominations and
        for the same aggregate principal amount, having endorsed thereon
        a Guarantee executed by the Guarantor, will be issued to the
        designated transferee or transferees.

             13.  Notices.  All notices to the holders of Securities will
        be published on a Business Day in an Authorized Newspaper (as
        defined in the Fiscal Agency Agreement) in New York City and in
        London, and, if the Securities are listed on the Luxembourg Stock
        Exchange and so long as listed thereon , in Luxembourg or, if
        either publication in London or Luxembourg is not practical, in
                                      A-40PAGE

        Wall Street Journal (Eastern edition), in London in the Financial
        Times and in Luxembourg in the Luxemburger Wort.  Notices shall
        be deemed to have been given on the date of publication as
        aforesaid or, if published on different dates, on the date of the
        first such publication.  A copy of each such notice will be
        mailed by the Fiscal Agent, on behalf of and at the expense of
        the Company, by first-class mail to each holder of a Registered
        Security at the registered address of such holder as the same

        coupon or by the Fiscal Agent with respect to any provisions
        thereof or of the Fiscal Agency Agreement, the recovery of any
        judgment against the Company or any action to enforce the same or
        any other circumstance which might otherwise constitute a legal
        or equitable discharge or defense of a guarantor.  The Guarantor
        hereby waives diligence, presentment, demand of payment, filing
        of claims with a court in the event of insolvency or bankruptcy

        whatsoever, and covenants that this Guarantee will not be
        discharged except by complete performance of the obligations
        contained in such Security and any such coupon and in this
        Guarantee.

             3.   (a)  The Guarantor will not merge or consolidate with,
        or sell or convey all or substantially all of its assets to, any
        other corporation, unless (i) either (A) the Guarantor shall be
        the surviving corporation in the case of a merger, (B) the assets
        sold or conveyed shall be owned by a corporation which,
        immediately following such sale or conveyance, is at least
        51%-owned by the Guarantor, provided that such sale or conveyance
                                      A-43PAGE
<PAGE>
        does not result in the reclassification, conversion, exchange or
        cancellation of outstanding shares of Common Stock of the
        Guarantor, or (C) (I) the surviving, resulting or transferee
        corporation shall expressly assume the due and punctual
        performance of all of the covenants and obligations of the
        Guarantor under the Guarantees and Fiscal Agency Agreement, by
        supplemental agreement reasonably satisfactory to the Fiscal
        Agent, and (II) the Fiscal Agent shall have received the
        documentation required in the context by the Fiscal Agency
        Agreement and (ii) the Guarantor or such successor corporation,
        as the case may be, shall not, immediately after such merger,

        performance of any covenants or obligations of the Guarantor
        under the Guarantees or the Fiscal Agency Agreement.

                  (b)  Upon any merger, consolidation, sale, conveyance
        or assumption as provided in Section 3(a), the successor or
        assuming corporation shall succeed to and be substituted for, and
        may exercise every right and power of and be subject to all the
        obligations of, the Guarantor under the Guarantees and Fiscal
        Agency Agreement, with the same effect as if such successor or
        assuming corporation had been named as the Guarantor therein and
        herein and the Guarantor shall be released from its obligations
        as obligor under the Guarantees and Fiscal Agency Agreement. 

             4.   (a)  The Guarantor, for itself, its successors and
        assigns, covenants and agrees, and each holder of Securities by
        his acceptance thereof, likewise covenants and agrees, that all
        obligations of the Guarantor relating to payment of the principal
        of, premium, if any, and interest and Additional Amounts
        (pursuant to Section 2 of the Securities) on each and all of the

        account of the Guarantees.

        Guarantees shall prevent at any time, except under the conditions
                                      A-48PAGE

        the principal amount hereof so exchanged shall be endorsed by the
        Fiscal Agent or its agents on the Schedule of Exchanges hereto,

        by the amount so exchanged.

             Until exchanged in full for definitive Securities, this
        Global Security shall in all respects be entitled to the same
        benefits under, and subject to the same terms and conditions of,

        shall be entitled to receive payment of interest hereon, except
        as provided above, or to convert this Global Security into shares
        of Common Stock of the Company or any other security, cash or
        other property.

        OF LAW RULES.

                    GUARANTEE OF THERMO ELECTRON CORPORATION

             1.   FOR VALUE RECEIVED, Thermo Electron Corporation, a
        corporation duly organized and existing under the laws of the
        State of Delaware (herein called the "Guarantor"), hereby
        unconditionally guarantees to the holder of the Security upon
        which this Guarantee is endorsed and to each holder of any coupon
        appertaining thereto the due and punctual payment of the
        principal of, premium, if any, and interest and any Additional
        Amounts (payable in accordance with Section 2 of such Security)
        on such Security when and as the same shall become due and
        payable, whether at the stated maturity or by declaration of
        acceleration, call for redemption, redemption at the option of
        the holder thereof or otherwise, according to the terms of such
        Security and of the Fiscal Agency Agreement referred to in the
        Security upon which this Guarantee is endorsed.  In case of the
        failure of the Company referred to in the Security upon which
        this Guarantee is endorsed punctually to make any such payment of
        principal, premium, if any, or interest or such Additional
        Amounts, if any, the Guarantor hereby agrees to cause any such
        payment to be made punctually when and as the same shall become
        due and payable, whether at the stated maturity or by declaration
        of acceleration, call for redemption, redemption at the option of
        the holder thereof or otherwise, and as if such payment were made
        by the Company. 

             2.   The Guarantor hereby agrees that its obligations
        hereunder shall be unconditional, irrespective of the validity,
        regularity or enforceability of such Security or the Fiscal
        Agency Agreement, the absence of any action to enforce the same,
        any waiver or consent by the holder of such Security or any such
        coupon or by the Fiscal Agent with respect to any provisions
        thereof or of the Fiscal Agency Agreement, the recovery of any
        judgment against the Company or any action to enforce the same or
        any other circumstance which might otherwise constitute a legal
        or equitable discharge or defense of a guarantor.  The Guarantor
        hereby waives diligence, presentment, demand of payment, filing
        of claims with a court in the event of insolvency or bankruptcy
        of the Company, any right to require a proceeding first against
        the Company, protest or notice with respect to such Security or
        coupon or the indebtedness evidenced thereby and all demands
        whatsoever, and covenants that this Guarantee will not be
        discharged except by complete performance of the obligations
        contained in such Security and any such coupon and in this
        Guarantee.

             3.   (a)  The Guarantor will not merge or consolidate with,
        or sell or convey all or substantially all of its assets to, any
        other corporation, unless (i) either (A) the Guarantor shall be
        the surviving corporation in the case of a merger, (B) the assets
        sold or conveyed shall be owned by a corporation which,
        immediately following such sale or conveyance, is at least
        51%-owned by the Guarantor, provided that such sale or conveyance
                                       B-6PAGE
<PAGE>
        does not result in the reclassification, conversion, exchange or
        cancellation of outstanding shares of Common Stock of the
        Guarantor, or (C) (I) the surviving, resulting or transferee
        corporation shall expressly assume the due and punctual
        performance of all of the covenants and obligations of the
        Guarantor under the Guarantees and Fiscal Agency Agreement, by
        supplemental agreement reasonably satisfactory to the Fiscal
        Agent, and (II) the Fiscal Agent shall have received the
        documentation required in the context by the Fiscal Agency
        Agreement and (ii) the Guarantor or such successor corporation,
        as the case may be, shall not, immediately after such merger,
        consolidation, sale or conveyance, be in default in the
        performance of any covenants or obligations of the Guarantor
        under the Guarantees or the Fiscal Agency Agreement.

                  (b)  Upon any merger, consolidation, sale, conveyance
        or assumption as provided in Section 3(a), the successor or
        assuming corporation shall succeed to and be substituted for, and
        may exercise every right and power of and be subject to all the
        obligations of, the Guarantor under the Guarantees and Fiscal
        Agency Agreement, with the same effect as if such successor or
        assuming corporation had been named as the Guarantor therein and
        herein and the Guarantor shall be released from its obligations
        as obligor under the Guarantees and Fiscal Agency Agreement. 

             4.   (a)  The Guarantor, for itself, its successors and
        assigns, covenants and agrees, and each holder of Securities by
        his acceptance thereof, likewise covenants and agrees, that all

        reorganization or readjustment.  For the purposes of this Section
        4, no consolidation, merger, conveyance or transfer made pursuant

        readjusted or securities of the Guarantor or any other
        corporation provided for by a plan of reorganization or
        readjustment the payment of which is subordinated, at least to
        the extent provided in this Section 4 with respect to the
        obligations of the Guarantor relating to the Securities and
        coupons, to the payment of all Senior Indebtedness of the
        Guarantor, provided that the rights of the holders of Senior
        Indebtedness of the Guarantor are not altered by such
        reorganization or readjustment), shall be received by the holders

        such payment or distribution shall be paid over to the holders of
        Senior Indebtedness of the Guarantor, ratably, for application to
        the payment of all Senior Indebtedness of the Guarantor remaining
        unpaid until all Senior Indebtedness of the Guarantor shall have
        been paid in full, after giving effect to any concurrent payment
        or distribution to the holders of such Senior Indebtedness of the
        Guarantor.

                       (iii)  Upon any distribution of assets of the
        Guarantor referred to in this Section, the holders of Securities
        shall be entitled to rely upon any final order or decree of a
        court of competent jurisdiction in which such dissolution,
        winding up, liquidation or reorganization proceedings are
        pending, and the holders of Securities shall be entitled to rely
        upon a certificate of the liquidating trustee or agent or other
        person making any distribution to the holders of Securities for
        the purpose of ascertaining the persons entitled to participate
        in such distribution, the holders of Senior Indebtedness of the
        Guarantor and other indebtedness of the Guarantor, the amount
        thereof or payable thereon, the amount or amounts paid or
        distributed thereon and all other facts pertinent thereto or to
        this Section.

                  (c) (i)   Upon the maturity of any Senior Indebtedness
        of the Guarantor by lapse of time, acceleration or otherwise, all
        principal thereof (and premium, if any) and interest due thereon,
        including interest thereon accruing after the commencement of any
        proceeding of the type referred to in paragraph (i) of Section
        4(b) above, and all other amounts due on or with respect thereto,
        shall first be paid in full, or such payment duly provided for in
        cash, before any payment, directly or indirectly, is made on
        account of the obligations of the Guarantor relating to the
        principal of, premium, if any, or interest and Additional Amounts
        (pursuant to Section 2 of the Securities) on the Securities or
        coupons.

                       (ii) Upon the happening of an event of default
        with respect to any Senior Indebtedness of the Guarantor, as
        defined therein or in the instrument under which it is
        outstanding, permitting the holders to accelerate the maturity
                                      B-10PAGE
<PAGE>
        thereof, then, unless and until such event of default shall have
        been cured or waived or shall have ceased to exist, no payment
        shall be made by the Guarantor, directly or indirectly, on
        account of the obligations of the Guarantor relating to the
        principal of, premium, if any, or interest and Additional Amounts
        (pursuant to Section 2 of the Securities) on the Securities and
        coupons. 

                  (d)  In case cash, securities or other property
        otherwise payable or deliverable to the holders of the Securities
        on account of the Guarantees shall have been applied, pursuant to
        Section 4(b) or (c), to the payment of Senior Indebtedness of the
        Guarantor, then, upon the payment in full of all Senior
        Indebtedness of the Guarantor, the holders of the Securities and
        coupons shall be subrogated to any rights of any holders of
        Senior Indebtedness of the Guarantor, to receive any further
        payments or distributions applicable to Senior Indebtedness of
        the Guarantor until the obligations of the Guarantor in respect
        of the Guarantees shall have been discharged in full, and such
        payments or distributions received by the holders of the
        Securities and coupons, by reason of such subrogation, of cash,
        securities or other property which otherwise would be paid or
        distributed to the holders of Senior Indebtedness of the
        Guarantor, shall, as between the Guarantor and its creditors
        other than the holders of Senior Indebtedness of the Guarantor,
        on the one hand, and the holders of the Securities and coupons on
        account of the Guarantees, on the other hand, be deemed to be a
        payment by the Guarantor on account of Senior Indebtedness of the
        Guarantor and not on account of the Securities and coupons. 

                  (e)  No present or future holder of any Senior
        Indebtedness of the Guarantor shall be prejudiced in any way in

        Ladies and Gentlemen:

             We are delivering this letter in connection with the
        purchase of 4-5/8% Convertible Subordinated Debentures due 2003
        (the "Debentures") of Thermo TerraTech Inc., a Delaware
        corporation (the "Company"), which are convertible into shares of
        Common Stock of the Company (the "Underlying Shares" and together
        with the Debentures, the "Restricted Securities"), all as
        described in the Company's Offering Circular dated April 26, 1996
        (the "Offering Circular").

             We represent, warrant and agree as follows:

                  1.   We understand and hereby acknowledge that the
             Debentures and, prior to the effectiveness of a registration
             statement filed with the Securities and Exchange Commission
             relating to the resale of the Underlying Shares, the
             Underlying Shares have not been registered under the
             Securities Act of 1933, as amended (the "Securities Act"),
             and may not be sold except as permitted in the following
             sentence.  We agree on our own behalf and on behalf of any
             investor account (as hereinafter defined) for which we are
             purchasing the Debentures to offer, sell or otherwise
             transfer such Restricted Securities prior to the date which
             is three years (or the then applicable holding period under
             Rule 144(k) under the Securities Act (or successor
             provision)) after the later of the date of original issue
             and the last date on which the Company or any affiliate of
                                       G-1PAGE
<PAGE>
             the Company was the owner of such Restricted Securities (or
             any predecessor thereto) (the "Resale Restriction
             Termination Date") only (a) to the Company, (b) pursuant to
             a registration statement which has been declared effective
             under the Securities Act, (c) for so long as the Debentures
             are eligible for resale pursuant to Rule 144A under the
             Securities Act, to a person we reasonably believe is a
             qualified institutional buyer under Rule 144A (a "QIB") that
             purchases for its own account or for the account of a QIB to
             whom notice is given that the transfer is being made in
             reliance on Rule 144A, (d) outside the United States in a
             transaction meeting the requirements of Rule 904 of
             Regulation S under the Securities Act, (e) in a transaction
             arranged by a broker or dealer registered under the
             Securities Exchange Act of 1934, as amended, to an
             institutional "accredited investor" within the meaning of
             subparagraph (a)(1), (2), (3), or (7) of Rule 501 under the
             Securities Act (an "Institutional Accredited Investor") that
             is purchasing Restricted Securities for its own account or
             for the account of such Institutional Accredited Investor,
             for investment purposes and not with a view to, or for offer
             or sale in connection with, any distribution in violation of
             the Securities Act or (f) pursuant to any other available
             exemption from the registration requirements of the
             Securities Act as confirmed in an opinion of counsel,
             acceptable in form and substance to the Company, and, in
             each case, in accordance with the applicable securities laws
             of any state of the United States or any other applicable
             jurisdiction and subject to any requirement of law that the
             disposition of our property or the property of such investor
             account or accounts be at all times within our or their
             control and in compliance with any applicable state
             securities laws.  The foregoing restrictions on resale will
             not apply subsequent to the Resale Restriction Termination
             Date.  If any resale or other transfer of the Restricted
             Securities is proposed to be made pursuant to clause (e)
             above prior to the Resale Restriction Termination Date, the
             transferor shall deliver a letter from the transferee
             containing representations and agreements substantially the
             same as those contained herein.  We acknowledge that the
             Company and the Fiscal Agent reserve the right prior to any
             offer, sale or other transfer prior to the Resale
             Restriction Termination Date of the Debentures and Common
             Stock pursuant to clause (d), (e) or (f) above to require
             the delivery of an opinion of counsel, certifications or
             other information acceptable to the Company and the Fiscal
             Agent in form and substance.

                  2.   We are an Institutional Accredited Investor within
             the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule
             501 under the Securities Act.

                  3.   Any purchase of Restricted Securities by us will
             be for our own account or for the account of one or more
                                       G-2PAGE
<PAGE>
             other Institutional Accredited Investors (an "investor
             account") as to which we exercise sole investment
             discretion.

                  4.   We are not acquiring the Restricted Securities
             with a view to, or for offer or sale in connection with, any
             distribution in violation of the Securities Act.

                  5.   We have such knowledge and experience in financial
             and business matters as to be capable of evaluating the
             merits and risks of purchasing the Restricted Securities,
             and we and any investor account for which we are acting are
             each able to bear the economic risk of our or its
             investment.

                  6.   We have received a copy of the Offering Circular
             and acknowledge that we have had access to such financial
             and other information, and have been afforded the
             opportunity to ask such questions of representatives of the
             Company and the Guarantor and receive answers thereto, as we
             deem necessary in connection with our decision to purchase
             Restricted Securities.

             We understand that the registrar and transfer agent will not
        be required to accept for registration of transfer any Restricted
        Securities, except upon presentation of evidence satisfactory to
        the Company and the Fiscal Agent that the foregoing restrictions
        on transfer have been complied with.  We further understand that
        the Restricted Securities will be in the form of definitive
        physical certificates and that such certificates will bear a
        legend reflecting the substance of paragraph 1 above.

             We shall provide to any person purchasing any Restricted
        Securities from us a notice advising such purchaser that
        transfers of the Debentures and the Underlying Shares are
        restricted as set forth herein.

             We understand that prior to any proposed offer of Debentures
        occurring before the Resale Restriction Termination Date, we must
        check the appropriate box set forth on the reverse of the
        certificate evidencing such Debentures relating to the manner of
        such transfer and submit the certificates to the Fiscal Agent.
        In addition, we understand that prior to any proposed transfer of
        Debentures or any proposed offer of Underlying Shares acquired
        upon conversion of Debentures when there is not effective
        registration statement covering such Underlying Shares to an
        institutional accredited investor occurring before the Resale
        Restriction Termination Date, we may be required to furnish to
        the Company and the Fiscal Agent such certifications, legal
        opinion or other information as they may reasonably require to
        confirm that the proposed transfer is being made pursuant to an
        exemption from, or in a transaction not subject to, the
        registration requirements of the Securities Act, and that
        transfers occurring before the Resale Restriction Termination
                                       G-3PAGE
<PAGE>
        Date to any other person pursuant to another available exemption
        under the Securities act will require an opinion of counsel
        satisfactory to the Company.

             We acknowledge that you and others will rely upon our
        confirmations, acknowledgments and agreements set forth herein,
        and we agree to notify you promptly in writing of any of our
        representations or warranties herein ceases to be accurate and
        complete. You are irrevocably authorized to produce this letter
        or a copy hereof to any interested party in any administrative or
        legal proceeding or official inquiry with respect to the matters
        covered hereby.

        ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS.

   Notes to Consolidated Financial Statements

   1.   Nature of Operations and Summary of Significant Accounting Policies

   Nature of Operations

        Thermo TerraTech Inc. (the Company) (formerly Thermo Process Systems
   Inc.) provides environmental services and infrastructure planning and
   design services, encompassing a range of specializations within the
   consulting and design, remediation and recycling, laboratory-testing, and
   metal-treating industries.

   Relationship with Thermo Electron Corporation

        The Company was incorporated on May 30, 1986, as an indirect, wholly
   owned subsidiary of Thermo Electron Corporation (Thermo Electron). As of
   March 30, 1996, Thermo Electron owned 14,501,958 shares of the Company's
   common stock, representing 83% of such stock outstanding.

   Principles of Consolidation

        The accompanying financial statements include the accounts of the
   Company and its majority- and wholly owned subsidiaries. All material
   intercompany accounts and transactions have been eliminated. Majority-owned
   subsidiaries include Thermo Remediation Inc. (Thermo Remediation), a
   publicly held subsidiary and Thermo EuroTech N.V. (Thermo EuroTech), a
   privately held subsidiary. 

   Fiscal Year

        The Company has adopted a fiscal year ending the Saturday nearest
   March 31. References to fiscal 1996, 1995, and 1994 are for the fiscal
   years ended March 30, 1996, April 1, 1995, and April 2, 1994, respectively.

   Revenue Recognition

        For the majority of its operations, the Company recognizes revenues
   upon completion of services it renders. Revenues from soil-remediation
   services are recognized as soil is processed. With respect to
   soil-remediation services, the Company bills customers upon receipt of the
   contaminated soil at its remediation centers. Amounts billed in excess of
   revenues recognized are classified as billings in excess of revenues earned
   in the accompanying balance sheet.

        Revenues and profits on substantially all contracts are recognized
   using the percentage-of-completion method. Revenues recorded under the
   percentage-of-completion method were $61,223,000 in fiscal 1996,
   $47,446,000 in fiscal 1995, and $46,072,000 in fiscal 1994. 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
                                       10PAGE

        (continued)

   customers upon the attainment of certain milestones specified in each
   contract. 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 Subsidiaries

        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 (Note 11).

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

        The Company adopted Statement of Financial Accounting Standards (SFAS)
   No. 109, "Accounting for Income Taxes," as of the beginning of fiscal 1994.
   Under SFAS No. 109, deferred income taxes are recognized 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. Prior to fiscal 1994, the
   Company recorded income taxes on timing differences between financial
   statement and tax treatment of income and expenses under Accounting
   Principles Board Opinion No. 11. Upon adoption of SFAS No. 109, the Company
   recorded a cumulative benefit of $500,000, which is included in the
   accompanying fiscal 1994 statement of income.

   Earnings per Share

        Earnings per share have been computed based on the weighted average
   number of shares outstanding during the year. Weighted average shares
   includes the assumed exercise of stock options and warrants computed using
   the treasury stock method. Fully diluted earnings per share have not been
   presented because the effect of the assumed exercise of stock options and
   warrants and the assumed conversion of the Company's subordinated
   convertible debentures would be immaterial.

   Cash and Cash Equivalents

        As of March 30, 1996, $29,552,000 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 90-day Commercial Paper
   Composite Rate plus 25 basis points, set at the beginning of each quarter.
   As of March 30, 1996, the Company's cash equivalents also include
   investments in a money market fund, which have an original maturity of
   three months or less. Cash equivalents are carried at cost, which
   approximates fair market value.

   Available-for-sale and Held-to-maturity Investments

        Pursuant to SFAS No. 115, "Accounting for Certain Investments in Debt
   and Equity Securities," short- and long-term debt and marketable equity
   securities that the Company considers available-for-sale are accounted for
   at market value. Debt securities that the Company intends to hold to
   maturity are accounted for at amortized cost (Note 2). Prior to fiscal
   1994, short- and long-term marketable equity securities were carried at the
   lower of cost or market value.

   Inventories

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

   Property, Plant and Equipment

        The costs of additions and improvements are capitalized, while
   maintenance and repairs are charged to expense as incurred. The Company
   provides for depreciation and amortization primarily using the
   straight-line method over the estimated useful lives of the property as
   follows: buildings and improvements - 5 to 40 years; machinery and
   equipment - 3 to 12 years; and leasehold improvements - the shorter of the
   term of the lease or the life of the asset. Soil-remediation units, which

   Other Assets

        Other assets in the accompanying balance sheet include the cost of
   acquired technology and other specifically identifiable intangible assets
   that are being amortized using the straight-line method over their
   estimated useful lives, which range from 5 to 12 years. These assets were
   $9,508,000 and $9,994,000, net of accumulated amortization of $4,791,000
   and $3,217,000, at fiscal year-end 1996 and 1995, 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 $6,735,000 and $4,721,000
   at fiscal year-end 1996 and 1995, 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 (Note
   12). 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." Foreign currency transaction gains and
   losses are included in the accompanying statement of income and are not
   material for the three years presented.

   Use of Estimates

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

   2.   Available-for-sale and Held-to-maturity Investments                   

        Effective April 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 that are
   classified as available-for-sale investments in the accompanying balance
   sheet 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 loss on available-for-
   sale investments." Effect of change in accounting principle in the
   accompanying fiscal 1994 statement of shareholders' investment represents
   the unrealized gain, net of related tax effects, pertaining to short-term
   available-for-sale investments held by the Company on April 2, 1994. 

        The aggregate market value, cost basis, and gross unrealized gains and
   losses of short- and long-term available-for-sale investments by major
   security type, as of March 30, 1996 and April 1, 1995, are as follows:

   of more than one year through five years. Actual maturities may differ from
   contractual maturities as a result of the Company's intent to sell these

   2.   Available-for-sale and Held-to-maturity Investments (continued)

        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 fiscal
   1996, 1995, and 1994 resulted from gross realized gains relating to the
   sale of available-for-sale investments.

        In order to meet the Company's obligation to the former owner of Elson
   T. Killam Associates, Inc., which the Company acquired in February 1995,
   the Company purchased U.S. treasury bonds that mature in February and May
   1998, the dates the Company's zero coupon promissory note is due (Note 3).
   These securities are classified as long-term held-to-maturity investments
   in the accompanying balance sheet and are carried at amortized cost. It is
   the Company's intent and ability to hold these securities to maturity.


   3.   Joint Venture and Acquisitions

   Joint Venture

        In May 1994, the Company entered into an agreement establishing an
   environmental services joint venture (the joint venture), with Thermo
   Instrument Systems Inc. (Thermo Instrument) that became effective April 4,
   1994. The Company contributed to the joint venture Terra Tech Labs, Inc.
   (later renamed Thermo Analytical Inc.) and approximately $31 million in
   cash and short-term investments, $15 million of which was borrowed from
   Thermo Electron pursuant to a promissory note (Note 8). Thermo Instrument
   contributed its environmental services businesses (Environmental Services
   Businesses) that consist of a national network of analytical laboratories,
   and businesses that provide nuclear-radiation safety and environmental
   science and consulting services. Accordingly, the joint venture's operating
   results were consolidated with the Company's operating results. Under the
   terms of the joint venture agreement, 66.67% of income earned by the joint
   venture from April 4, 1994 to April 1, 1995 was allocated to Thermo
   Instrument.

        Because the Company and the Environmental Services Businesses were
   deemed for accounting purposes to be under control of their common majority
   owner, Thermo Electron, the transaction was accounted for at historical
   cost in a manner similar to the pooling-of-interests method. Accordingly,
   in fiscal 1994, all historical financial information presented was restated
   to include the accounts and operations of the Environmental Services
   Businesses. In fiscal 1994, amounts earned by the Environmental Services
   Businesses were allocated to Thermo Instrument through minority interest
   expense in the accompanying financial statements.

   Notes to Consolidated Financial Statements

   3.   Joint Venture and Acquisitions (continued)

        Effective April 2, 1995, the Company and Thermo Instrument dissolved
   the joint venture and the Company purchased the businesses formerly
   operated by the joint venture from Thermo Instrument for $34,267,000 in
   cash. As a result of this transaction, the Company increased its ownership
   in the businesses operated by the joint venture from 51% to 100%. Based on
   unaudited data, if the acquisition of Thermo Instrument's share of such
   businesses by the Company had occurred at the beginning of fiscal 1994, net
   income and earnings per share on a pro forma basis would have been
   $4,574,000 and $.27, respectively, for fiscal 1995 and $5,326,000 and $.32,
   respectively, for fiscal 1994. The Company borrowed the purchase price from
   Thermo Electron through the issuance of a $35,000,000 promissory note
   (Note 8).

        In June 1995, the Company transferred three businesses formerly
   operated by the joint venture, collectively known as the Nuclear Services
   Group (renamed Thermo Nutech), to Thermo Remediation in exchange for
   1,583,360 shares of Thermo Remediation common stock.

   Acquisitions

        In December 1995, Thermo Remediation acquired Remediation
   Technologies, Inc. (ReTec), a provider of integrated environmental services
   such as the remediation of industrial sites contaminated with organic
   wastes and residues. The purchase price of $29,672,000 consisted of
   $18,462,000 in cash, 227,250 shares of Thermo Remediation's common stock
   and 75,750 warrants to purchase shares of Thermo Remediation's common stock
   at $14.85 per share, valued in the aggregate at $3,716,000, and
   approximately $7,494,000 attributable to the conversion of outstanding
   ReTec stock options into Thermo Remediation stock options of equivalent
   intrinsic value at the date of acquisition.

        In May 1995, the Company acquired substantially all of the assets of
   Lancaster Laboratories, Inc. and its affiliate Clewmark Holdings
   (collectively Lancaster Laboratories). Lancaster Laboratories, based in
   Lancaster, Pennsylvania, is a provider of high-quality analytical services
   to the environmental, food, and pharmaceutical industries. The purchase
   price for the assets was $25,329,000 in cash, which included the repayment
   of $5,333,000 of debt.

        In March 1995, the Company's Thermo EuroTech subsidiary acquired all
   of the outstanding capital stock of Refining and Trading Holland B.V.,
   which conducts business under the name North Refinery, from Stalt Holding
   B.V. North Refinery, located in Delfzijl, Holland. North Refinery
   specializes in processing "off-spec" and contaminated petroleum fluids into
   usable products such as gas oil, diesel oil, and fuel oil. The purchase
   price for North Refinery's stock was 9,568,000 Dutch guilders
   (approximately $6,180,000) and 228,570 shares of Thermo EuroTech's capital
   stock, valued at 1,327,000 Dutch guilders (approximately $857,000). Thermo
   EuroTech has also agreed to pay, after the fifth anniversary date of the
   closing, an amount equal to 20% of the amount by which the cumulative
   pretax profits of North Refinery's business over the five-year period
   ending on such anniversary exceeds 5,000,000 Dutch guilders.

   3.   Joint Venture and Acquisitions (continued)

        In February 1995, the Company acquired all of the outstanding capital
   stock of Engineering, Technology and Knowledge Corporation (ETKC) from Nord
   Est S.A., a French industrial company (Nord Est). ETKC's sole subsidiary,
   Elson T. Killam Associates, Inc. (Killam Associates), is a leading provider
   of comprehensive environmental consulting and professional engineering
   services in selected areas of the U.S. The purchase price for ETKC's stock
   was $13,273,000 in cash and a zero coupon promissory note with a face value
   of $28,000,000 and a present value of $22,300,000 as of the acquisition
   closing date, payable in February and May 1998. The Company has also agreed
   to pay, after the third anniversary date of the closing, an amount equal to
   30% of the amount by which Killam Associates' cumulative net income for the
   three-year period ending on such anniversary exceeds $13 million. In a
   related transaction, certain members of Killam Associates' senior
   management (the Killam Management) exchanged outstanding options to
   purchase shares of Killam Associates' capital stock for options to purchase
   an aggregate of 847,678 shares of the Company's common stock, which options
   were valued at $6,923,000. Additional options to purchase shares of Killam
   Associates' capital stock were canceled in exchange for cash payments to
   the Killam Management in the aggregate amount of $1,922,000. The Company
   borrowed the cash portion of the purchase price, including cash used to
   purchase U.S. treasury bonds to collateralize the promissory note delivered
   to Nord Est, from Thermo Electron through the issuance of a $38 million
   promissory note (Note 8).

        In October 1994, Thermo Remediation acquired a soil-remediation
   facility in South Tacoma, Washington, (renamed TPST Woodworth) from
   Woodworth & Company, Inc. The purchase price for TPST Woodworth was
   $4,701,000 in cash. In connection with the financing of acquisitions,
   Thermo Remediation issued to Thermo Electron a $4,000,000 promissory note
   (Note 8). During fiscal 1995, Thermo Remediation and the environmental
   services joint venture made other acquisitions for an aggregate of $14.2
   million in cash.

        In January 1994, the Company acquired Terra Tech Labs, Inc. (Terra
   Tech), a privately held company specializing in fast-response testing of
   petroleum-contaminated soils and groundwater in the southwestern region of
   the U.S. The acquisition was made for $1,924,000 in cash, including a
   $424,000 payment made as a result of the business having achieved certain
   performance goals over a two-year period. Terra Tech has a facility in
   Santa Ana, California, as well as four mobile units, which provide services
   primarily to the petroleum industry and consulting engineers.

        In November 1993, the Company acquired a fluids recovery company based
   in Mesa, Arizona, (renamed Thermo Fluids) for $2,650,000 in cash and
   immediately transferred it to Thermo Remediation in exchange for a
   $2,650,000 principal amount 3 7/8% subordinated convertible note due 2000.
   In addition, due to Thermo Fluids having met certain performance criteria,
   on February 1, 1995, the Company issued to the former owner of Thermo
   Fluids, 178,060 restricted shares of its common stock valued at $840,000.
   Thermo Remediation, in turn, issued to the Company 127,369 restricted
   shares of its common stock valued at $840,000. In August 1994, Thermo
   Remediation loaned $700,000, included in other assets in the accompanying
   fiscal 1996 and 1995 balance sheet, to the former owner of Thermo Fluids in
   connection with the termination of his employment with Thermo Fluids and
   the settlement of the parties' respective obligations to one another. This

   3.   Joint Venture and Acquisitions (continued)

   obligation is represented by a promissory note bearing interest at a rate
   equal to the rate of interest on one-year U.S. treasury notes, adjusted on
   an annual basis, and is secured by a pledge of the Company's common stock
   issued to the former owner. The note is payable in three equal installments
   due in March 1997, December 1997, and December 1998.

        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 fiscal 1996, 1995,
   and 1994 exceeded the estimated fair value of the acquired net assets by
   $67,795,000, which is being amortized over 40 years. Allocation of the
   purchase price for these acquisitions was based on estimates of the fair
   value of the net assets acquired and, for acquisitions completed in fiscal
   1996, 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, ReTec, and Lancaster Laboratories on
   a pro forma basis, assuming the companies had been combined since the
   beginning of fiscal 1995, and for the Company, North Refinery, Killam
   Associates, and TPST Woodworth on a pro forma basis, assuming the companies
   had been combined since the beginning of fiscal 1994. 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 fiscal 1995 or 1994, as
   applicable.

        Other accrued expenses in the accompanying balance sheet includes
   $423,000 and $1,848,000 at fiscal year-end 1996 and 1995, respectively, for
   estimated severance, relocation, and other exit costs 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 1986, permit the
   grant of nonqualified and incentive stock options. A third plan, adopted in
   fiscal 1994, permits the grant of a variety of stock and stock-based awards
   as determined by the human resources committee of the Company's Board of
   Directors (the Board Committee), including restricted stock, stock options,
                                       18PAGE

   Notes to Consolidated Financial Statements

   4.   Stock-based Compensation Plans (continued)

   stock bonus shares, or performance-based shares. To date, only nonqualified
   stock options have been awarded under these plans. The option recipients
   and the terms of options granted under these plans are determined by the
   Board Committee. Generally, options granted to date are exercisable
   immediately, but are subject to certain transfer restrictions and the right
   of the Company to repurchase shares issued upon exercise of the options at
   the exercise price, upon certain events. The restrictions and repurchase
   rights generally lapse ratably over periods ranging from three to ten years
   after the first anniversary of the grant date, depending on the term of the
   option, which may range from five to twelve years. Nonqualified stock
   options may be granted at any price determined by the Board Committee,
   although incentive stock options must be granted at not less than the fair
   market value of the Company's stock on the date of grant. Generally, all
   options have been granted at fair market value. The Company also has a
   directors' stock option plan, adopted in September 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 to seven
   years after the date of grant. In addition to the Company's stock-based
   compensation plans, certain officers and key employees may also participate
   in the stock-based compensation plans of Thermo Electron or its
   majority-owned subsidiaries.

        In connection with the acquisition of Killam Associates in February
   1995, the Company assumed certain outstanding options granted under Killam
   Associates' nonqualified stock option plan. Such options were converted
   into options to purchase shares of the Company's common stock, in
   accordance with the original terms of the options. All of the options
   converted were fully vested and exercisable immediately pursuant to their
   original terms. Such options expire ten years from the date of grant.

   Employee Stock Purchase Plan

        The majority of the Company's full-time U.S. employees are eligible to
   participate in an employee stock purchase plan sponsored by the Company.
   Prior to the November 1995 plan year, shares of the Company's and Thermo
   Electron's common stock could be purchased at the end of a 12-month plan
   year at 85% of the fair market value at the beginning of the plan year, and
   the shares purchased were subject to a one-year resale restriction.
   Effective November 1, 1995, the applicable shares of common stock may be
   purchased at 95% of the fair market value at the beginning of the plan
   year, and the shares purchased are subject to a six-month resale
   restriction. Shares are purchased through payroll deductions of up to 10%
   of each participating employee's gross wages. During fiscal 1996, 1995, and
   1994, the Company issued 44,259 shares, 21,999 shares, and 28,845 shares,
   respectively, of its common stock under this plan. Employees of the

   5.   Employee Benefit Plans (continued)

   Environmental Services Businesses participated in an employee stock
   purchase plan sponsored by Thermo Instrument through November 1994.
   Thereafter, they became eligible to participate in the Company's employee
   stock purchase plan.

   401(k) Savings Plan and Employee Stock Ownership Plan

        The majority of the Company's full-time U.S. employees are eligible to
   participate in Thermo Electron's 401(k) savings plan and, prior to January
   1, 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. Certain subsidiaries of the Company also have a defined
   contribution retirement plan, a union-sponsored, collectively bargained
   multi-employer pension plan, and 401(k) savings plans. For these plans, the
   Company contributed and charged to expense $1,439,000, $1,654,000, and
   $1,465,000 in fiscal 1996, 1995, and 1994, 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)

        During fiscal 1996, the Company reversed previously established tax
   reserves totaling $750,000 that were no longer required as a result of the
   completion of certain revenue agent reviews.

        The valuation allowance relates to the uncertainty surrounding the
   realization of the tax benefits attributable to federal operating loss and
   credit carryforwards and purchase accounting reserves related to various
   acquisitions. The valuation allowance will be used to reduce cost in excess
   of net assets of acquired companies when any portion of the related
   deferred tax asset is recognized.

        A provision has not been made for U.S. or additional foreign taxes on
   $505,000 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 and Contingencies

   Operating Leases

        The Company leases land, office and manufacturing facilities, and
   equipment under operating leases expiring at various dates through fiscal
   2059. The accompanying statement of income includes expenses from operating
   leases of $4,632,000, $2,491,000, and $2,509,000 in fiscal 1996, 1995, and
   1994, respectively. Future minimum payments due under noncancellable
   operating leases at March 30, 1996, are $3,893,000 in fiscal 1997;
   $2,483,000 in fiscal 1998; $1,866,000 in fiscal 1999; $1,338,000 in fiscal
   2000; $1,011,000 in fiscal 2001; and $1,112,000 in fiscal 2002 and
   thereafter. Total future minimum lease payments are $11,703,000. See Note 9
   for office and manufacturing facilities leased from Thermo Electron.

        In March 1991, the Company's TPST Virginia subsidiary entered into a
   seven-year agreement, terminable at the Company's option with 90 days'
   notice, to operate one or more of its soil-remediation units at a site
   owned by a third party. Under the terms of the agreement, the Company pays
   a fee based on the gross remediation revenues generated from the operations
   at the site, less certain operating costs incurred by the Company. The
   accompanying statement of income includes expenses relating to this
   agreement of $147,000, $307,000, and $410,000 in fiscal 1996, 1995, and
   1994, respectively.

   Contingencies

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

        The 6 1/2% and 4 7/8% subordinated convertible debentures 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 the guarantee. During fiscal 1996,
   $365,000 principal amount of the 6 1/2% debentures was converted into
   35,332 shares of the Company's common stock.

        The annual requirements for long-term obligations as of March 30,
   1996, are $15,216,000 in fiscal 1997; $18,836,000 in fiscal 1998;
   $24,400,000 in fiscal 1999; $2,800,000 in fiscal 2000; $38,100,000 in

   requirements of long-term obligations are $170,600,000. See Note 13 for
   information pertaining to the fair value of the Company's long-term
   obligations.

   Short-term Obligations and Other Financing Arrangements

        The Company's Thermo EuroTech subsidiary has a line of credit,
   denominated in Netherlands guilders, under which approximately $6,050,000
   may be borrowed at the Netherlands discount rate plus 125 basis points. At
   March 30, 1996, $3,995,000 was outstanding under this arrangement, bearing
   interest at 5.25%.

   8.   Short- and Long-term Obligations and Other Financing Arrangements
        (continued)

        In December 1994, Thermo Remediation borrowed $4,000,000 from Thermo
   Electron through issuance of a promissory note due June 29, 1995, and
   bearing interest at the 90-day Commercial Paper Composite Rate plus 25
   basis points, set at the beginning of each quarter. The average interest
   rate on the note was 6.4% and 6.5% in fiscal 1996 and 1995, respectively.
   The promissory note was repaid in full in June 1995. The promissory note is
   included in notes payable and current maturities of long-term obligations
   in the accompanying fiscal 1995 balance sheet.


   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 returns, centralized cash management, and certain
   financial and other services, for which the Company pays Thermo Electron
   annually an amount equal to 1.0% of the Company's revenues. Prior to
   January 1, 1996, the Company paid an annual fee equal to 1.20% of the
   Company's revenues. Prior to January 1, 1995, the Company paid an annual
   fee equal to 1.25% of the Company's revenues. The annual fee is reviewed
   and adjusted annually by mutual agreement of the parties. For these
   services, the Company was charged $2,577,000, $1,653,000, and $1,377,000,
   in fiscal 1996, 1995, and 1994, respectively. The corporate services
   agreement is renewed annually but can be terminated upon 30 days' prior
   notice by the Company or upon the Company's withdrawal from the Thermo
   Electron Corporate Charter (the Thermo Electron Corporate Charter defines
   the relationship among Thermo Electron and its majority-owned
   subsidiaries). Management believes that the service fee charged by Thermo
   Electron is reasonable and that such fees are representative of the
   expenses the Company would have incurred on a stand-alone basis. 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.

   Development Agreement

        The Company and Thermo Electron entered into a development agreement
   under which Thermo Electron agreed to fund up to $4.0 million of the direct
   and indirect costs of the Company's development of soil-remediation
   centers. In exchange for this funding, the Company granted Thermo Electron
   a royalty equal to approximately 3% of net revenues from soil-remediation
   services performed at the centers developed under the agreement. The
   royalty payments may cease if the amounts paid by the Company yield a
   certain internal rate of return to Thermo Electron on the funds advanced to
   the Company under the agreement. The Company recorded contract revenues of
   $776,000 under this agreement for development costs expended in fiscal
   1994. As of October 2, 1993, funding under this agreement was completed.
   Two sites have been developed under this agreement. The Company paid

   9.   Related Party Transactions (continued)

   royalties of $332,000, $432,000, and $351,000 in fiscal 1996, 1995, and
   1994, respectively, relating to this agreement, which are included in
   selling, general and administrative expenses in the accompanying statement
   of income.

   Operating Leases

        The Company leases or subleases two office and manufacturing
   facilities from Thermo Electron under lease agreements expiring in fiscal
   1997 and 2004. The accompanying statement of income includes expenses from
   the operating lease and sublease of $486,000, $537,000, and $426,000 in
   fiscal 1996, 1995, and 1994, respectively. The future minimum payments due
   under the lease and sublease as of March 30, 1996, are $813,000 in fiscal
   1997 through 2000; $772,000 in fiscal 2001; and $2,589,000 in fiscal 2002
   and thereafter. Total future minimum payments are $6,613,000.

   Repurchase Agreement

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

   Short- and Long-term Obligations

        See Note 8 for a description of short- and long-term obligations of
   the Company held by Thermo Electron.


   10.  Common Stock

        At March 30, 1996, the Company had reserved 5,891,401 unissued shares
   of its common stock for possible issuance under stock-based compensation
   plans, possible issuance upon conversion of the 6 1/2% subordinated
   convertible debentures, and exercise of warrants.


   11.  Transactions in Stock of Subsidiaries

        During fiscal 1996, Thermo Remediation sold 500,000 shares of its
   common stock in a private placement at $13.25 per share for net proceeds of
   $6,625,000, resulting in a gain of $2,742,000. During fiscal 1996, Thermo
   Remediation issued 227,250 shares of its common stock in connection with
   the acquisition of ReTec (Note 3), resulting in a gain of $1,385,000.

        During fiscal 1995, the Company's Thermo EuroTech subsidiary completed
   private placements in Europe of 700,331 shares of its common stock at $3.75
   per share for net proceeds of $2,423,000, resulting in gains of $829,000.
   During fiscal 1995, the Company's Thermo Remediation subsidiary completed a
   private placement of 75,000 shares of its common stock at $9.67 per share
   for net proceeds of $715,000, resulting in a gain of $229,000.

   11.  Transactions in Stock of Subsidiaries (continued)

        During fiscal 1994, the Company's Thermo Remediation subsidiary
   completed an initial public offering of 1,785,000 shares of its common
   stock at $8.33 per share for net proceeds of $13,505,000, resulting in a
   gain of $3,886,000. During fiscal 1994, Thermo Remediation also completed a
   private placement consisting of 300,000 units, comprising an aggregate of
   300,000 shares of Thermo Remediation common stock, valued at $6.59 per
   share, and warrants to purchase 300,000 shares of Thermo Remediation common
   stock, valued at $.33 per warrant. The warrants expired in whole upon the
   closing of Thermo Remediation's initial public offering at a price above
   the warrants' exercise price of $6.93 per share. Net proceeds from the sale
   were $2,077,000, resulting in a gain of $602,000.

        Dividends declared by the Company's majority-owned subsidiaries were
   $2,491,000, $2,012,000, and $2,127,000 in fiscal 1996, 1995, and 1994,
   respectively. Dividends declared by the Company's majority-owned
   subsidiaries include $1,667,000 in fiscal 1996 that was allocated to the
   Company and reinvested in 117,805 shares of Thermo Remediation's common
   stock pursuant to Thermo Remediation's Dividend Reinvestment Plan adopted
   in fiscal 1995, $1,316,000 in fiscal 1995 reinvested in 113,491 shares of
   Thermo Remediation's common stock, and $1,608,000 in fiscal 1994 that was
   paid to the Company in cash.

        The Company has 700,500 warrants to purchase its common stock
   outstanding at March 30, 1996, which are exercisable at $10.00 - $11.34 per
   share and expire in fiscal 2001. The warrants were issued in fiscal 1992
   and 1993 in connection with private placements completed by three of the
   Company's soil-recycling subsidiaries.

        The Company's percentage ownership of its majority-owned subsidiaries
   at year-end was as follows:

                                                    1996      1995      1994

   12.  Nonrecurring Costs

        Following the purchases of Killam Associates in February 1995, the
   businesses formerly operated by the Company's environmental services joint
   venture with Thermo Instrument in April 1995, and Lancaster Laboratories in
   May 1995, the primary growth focus of the Company has become environmental
   infrastructure services. The Company no longer expects to reinvest in the
   thermal-processing equipment business. The Company's analysis indicates
   that the expected future undiscounted cash flow from this business will be
   insufficient to recover the Company's investment. Accordingly, in the
   second quarter of fiscal 1996, the Company wrote off $4,995,000 of cost in
   excess of net assets of acquired company associated with the
   thermal-processing equipment business. This noncash expense is
   nondeductible for tax purposes.

   12.  Nonrecurring Costs (continued)

        In September 1995, the Company sold to a management group the assets
   of a small civil engineering design office in Williston, Vermont, that was
   no longer included in the geographic expansion plans of the Company. An
   intangible asset of $569,000 associated with this office was not recovered
   in the sale price and, accordingly, was written off during the second
   quarter of fiscal 1996. This noncash expense is nondeductible for tax
   purposes. Sales and earnings of this office were not material to the
   Company.

        In fiscal 1994, the Company wrote off $2,661,000 of mobile
   soil-remediation assets and other related expenses. The Company decided to
   no longer actively pursue mobile soil-remediation projects.


   13.  Fair Value of Financial Instruments

        The Company's financial instruments consist primarily of cash and cash
   equivalents, available-for-sale and held-to-maturity 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 and held-to-maturity investments, and long-term
   obligations, approximate 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. Held-to-maturity investments in the accompanying
   balance sheet are carried at amortized cost. The fair values are disclosed
   on the accompanying balance sheet and were determined based on quoted
   market prices.

        The fair value of long-term obligations was determined based on quoted
   market prices and on borrowing rates available to the Company at the
   respective year-ends. The fair value of convertible obligations at year-end
   fiscal 1996 exceeds the carrying amount primarily due to the market price
   of the Company's 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:

                                  1996                         1995

   14.  Significant Customers

        During fiscal 1996, 1995, and 1994 revenues derived from U.S.
   government agencies accounted for 10%, 6%, and 16%, respectively, of the
   Company's total revenues.

   Issuance of Subordinated Convertible Debentures

        In May 1996, the Company issued and sold $115 million principal amount
   of 4 5/8% subordinated convertible debentures due 2003. The debentures are

   per share. Upon completion of the debenture offering, the Company repaid
   its $15 million and $35 million notes payable to Thermo Electron.

   Report of Independent Public Accountants                                  

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

        We have audited the accompanying consolidated balance sheet of Thermo
   TerraTech Inc. (a Delaware corporation and an 83%-owned subsidiary of
   Thermo Electron Corporation) and subsidiaries as of March 30, 1996 and
   April 1, 1995, and the related consolidated statements of income,
   shareholders' investment and cash flows for each of the three years in the
   period ended March 30, 1996. These consolidated financial statements are
   the responsibility of the Company's management. Our responsibility is to
   express an opinion on these consolidated financial statements based on our
   audits.

        We conducted our audits in accordance with generally accepted auditing
   standards. Those standards require that we plan and perform the audit to
   obtain reasonable assurance about whether the consolidated financial
   statements are free of material misstatement. An audit includes examining,
   on a test basis, evidence supporting the amounts and disclosures in the
   financial statements. An audit also includes assessing the accounting
   principles used and significant estimates made by management, as well as
   evaluating the overall financial statement presentation. We believe that
   our audits provide a reasonable basis for our opinion.

        In our opinion, the consolidated financial statements referred to
   above present fairly, in all material respects, the financial position of
   Thermo TerraTech Inc. and subsidiaries as of March 30, 1996 and April 1,
   1995, and the results of their operations and their cash flows for each of
   the three years in the period ended March 30, 1996, in conformity with
   generally accepted accounting principles.

        As discussed in Note 1 to the consolidated financial statements,
   effective April 4, 1993, the Company changed its method of accounting for
   income taxes and effective April 2, 1994, the Company changed its method of
   accounting for investments in debt and marketable equity securities.

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

   Overview

        The Company is a provider of environmental services and infrastructure
   planning and design services, encompassing a range of specializations
   within the consulting and design, remediation and recycling, and
   laboratory-testing industries. The Company also provides metal-treating
   services and thermal-processing systems used to treat primary metals and
   metal parts. The Company's environmental services businesses are affected
   by several factors, most particularly, extreme weather variations,
   government spending, and deregulation of remediation activities.

        Consulting and Design - The Company's wholly owned Bettigole Andrews &
   Clark and Normandeau Associates subsidiaries provide both private and
   public sector clients with a range of consulting services that address
   transportation planning and design, and natural resource management issues,
   respectively. In February 1995, the Company acquired Elson T. Killam
   Associates Inc. (Killam Associates), which provides environmental
   consulting and engineering services and specializes in wastewater treatment
   and water resources management.

        Remediation and Recycling - The Company's majority-owned Thermo
   Remediation Inc. (Thermo Remediation) subsidiary operates a network of
   soil-remediation centers, serving customers in more than a dozen states on
   the East and West coasts by providing thermal treatment of soil to remove
   and destroy petroleum contamination caused by leaking underground and
   aboveground storage tanks, spills, and other sources. In addition, Thermo
   Remediation's Thermo Fluids subsidiary, located in Arizona, offers
   fluids-recycling services including waste motor oil and wastewater
   treatment throughout Arizona, Nevada, and in neighboring states. Through
   its Thermo Nutech subsidiary, Thermo Remediation provides services to
   remove radioactive contaminants from sand, gravel, and soil, as well as
   health physics, radiochemistry laboratory, and radiation dosimetry
   services. In December 1995, Thermo Remediation acquired Remediation
   Technologies, Inc. (ReTec), which provides integrated environmental
   services such as remediation of industrial sites contaminated with organic
   wastes and residues. The Company's majority-owned Thermo EuroTech N.V.
   (Thermo EuroTech) subsidiary, located in the Netherlands, provides
   wastewater treatment services as well as services to test, remove, and
   install underground storage tanks. In March 1995, Thermo EuroTech acquired
   Refining and Trading Holland B.V. (North Refinery), which specializes in
   converting "off-spec" and contaminated petroleum fluids into usable oil
   products.

        Laboratory-testing - The Company's wholly owned Thermo Analytical
   subsidiary operates a network of analytical laboratories that provide
   environmental testing services to commercial and government clients
   throughout the U.S. The May 1995 acquisition of Lancaster Laboratories,
   Inc. (Lancaster Laboratories) expands the Company's range of contract
   services beyond environmental testing to the pharmaceutical- and
   food-testing industries.

        Metal-treating - The Company performs metallurgical processing
   services using thermal-treatment equipment at locations in California and
   Minnesota. The Company also designs, manufactures, and installs advanced
   custom-engineered, thermal-processing systems through its equipment
   division located in Michigan.

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

   Overview (continued)

        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 Corporation (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 which
   could become effective for fiscal years beginning after December 15, 1996.

   Results of Operations

   Fiscal 1996 Compared With Fiscal 1995

        Total revenues increased 62% to $217.4 million in fiscal 1996 from
   $133.8 million in fiscal 1995. Consulting and design services revenues
   increased to $74.0 million in fiscal 1996 from $40.3 million in fiscal
   1995, primarily as a result of an increase of $34.2 million due to the
   inclusion of revenues for a full year from Killam Associates, which was
   acquired in February 1995. Revenues from remediation and recycling services
   increased to $77.0 million in fiscal 1996 from $58.2 million in fiscal
   1995, primarily due to the inclusion of $24.4 million in revenues from
   businesses acquired or constructed in late fiscal 1995 and 1996, and higher
   revenues from a long-term environmental restoration contract for the U.S.
   Department of Energy's (DOE) Hanford site (Hanford), which began in the
   second quarter of fiscal 1995. These increases were offset in part by lower
   soil-remediation services revenues resulting from a decrease in the volume
   and price of soil processed as a result of regulatory uncertainties at
   several sites, competitive pricing pressures, and severe weather conditions
   primarily in the fourth quarter of fiscal 1996. Revenues from
   radiochemistry laboratory work also decreased, reflecting a reduction in
   spending at the DOE and delays in federal government budget appropriations.
   Revenues from laboratory-testing services, excluding the radiochemistry
   laboratory services included in remediation and recycling services, 
                                       32PAGE

   Operations (continued)

   Fiscal 1996 Compared With Fiscal 1995 (continued)

   increased to $34.6 million in fiscal 1996 from $8.6 million in fiscal 1995,
   reflecting the inclusion of $29.1 million in revenues from Lancaster
   Laboratories, which was acquired in May 1995, offset in part by a decline
   in revenues due to reduced federal spending and a shift in business from
   existing sites to the newly acquired Lancaster Laboratories. Metal-treating
   revenues increased to $31.8 million in fiscal 1996 from $26.7 million in
   fiscal 1995, primarily due to an increase in demand for thermal-processing
   equipment.

        The gross profit margin increased to 29% in fiscal 1996 from 26% in
   fiscal 1995, due to the inclusion of higher-margin revenues from Killam
   Associates and Lancaster Laboratories, offset in part by lower margins from
   remediation and recycling services revenues primarily due to competitive
   pricing pressures and lower revenues from higher-margin radiochemistry
   laboratory work. In addition, gross profit margins at Thermo EuroTech
   decreased as a result of severe winter weather and market conditions in
   fiscal 1996.

        During the second quarter of fiscal 1996, the Company wrote off
   $4,995,000 of cost in excess of net assets of acquired company related to
   its thermal-processing equipment business. In addition, in the second
   quarter of fiscal 1996, the Company incurred a loss of $569,000 as a result
   of the sale of an engineering office. These noncash expenses are
   nondeductible for tax purposes (Note 12).

        Selling, general and administrative expenses as a percentage of
   revenues increased to 22% in fiscal 1996 from 20% in fiscal 1995, primarily
   due to the inclusion of higher selling, general and administrative expenses
   as a percentage of revenues at Killam Associates and, to a lesser extent,
   at Thermo EuroTech due to the settlement of several contract disputes.

        Interest income increased to $5.1 million in fiscal 1996 from $3.3
   million in fiscal 1995 as a result of higher invested balances following
   the issuance of $38 million principal amount of 4 7/8% subordinated
   convertible debentures by Thermo Remediation in May 1995 and a private
   placement of shares of Thermo Remediation's common stock in May 1995,
   offset in part by funds expended to purchase the business formerly operated
   by the environmental services joint venture from Thermo Instrument Systems
   Inc. (Thermo Instrument) (Note 3). Interest expense increased to $10.7
   million in fiscal 1996 from $2.9 million in fiscal 1995 as a result of
   borrowings from Thermo Electron for the February 1995 acquisition of Killam
   Associates and the May 1995 acquisition of Lancaster Laboratories, and the
   issuance of the 4 7/8% subordinated convertible debentures by Thermo
   Remediation in May 1995. Interest expense will increase in fiscal 1997 as a
   result of the May 1996 issuance of $115 million principal amount of 4 5/8%
   subordinated convertible debentures by the Company (Note 16).

        As a result of the issuance of stock by Thermo Remediation in fiscal
   1996 and 1995, and by Thermo EuroTech in fiscal 1995, the Company recorded
   gains of $4,127,000 and $1,343,000 in fiscal 1996 and 1995, respectively.
   These gains represent increases in the Company's proportionate share of the
   subsidiaries' equity and are classified as gain on issuance of stock by
   subsidiaries in the accompanying statement of income.

   Operations (continued)

   Fiscal 1996 Compared With Fiscal 1995 (continued)

        The effective tax rates were 44% and 24% in fiscal 1996 and 1995,
   respectively. The effective tax rate in fiscal 1996 was higher than the
   statutory federal income tax rate primarily due to the nondeductible
   write-off of cost in excess of net assets of acquired company and the loss
   on sale of assets, offset in part by the nontaxable gains on issuance of
   stock by subsidiaries and the reversal of previously established tax
   reserves of $750,000 that were no longer required due to the completion of
   certain revenue agent reviews. In fiscal 1995, the effective tax rate was
   lower than the statutory federal income tax rate primarily due to the
   exclusion of income taxed directly to a minority partner.

        Minority interest expense decreased to $1.2 million in fiscal 1996
   from $4.3 million in fiscal 1995 due primarily to the Company's purchase of
   the businesses formerly operated by the Company's joint venture with Thermo
   Instrument (Note 3).

   Fiscal 1995 Compared With Fiscal 1994

        Total revenues were $133.8 million in fiscal 1995, compared with
   $110.1 million in fiscal 1994, an increase of 21%. Revenues from consulting
   and design services increased to $40.3 million in fiscal 1995 from $29.7
   million in fiscal 1994, primarily due to the inclusion of approximately
   $7.2 million in revenues from Killam Associates, which was acquired in
   February 1995. Revenues from remediation and recycling services increased
   20% to $58.2 million in fiscal 1995 from $48.7 million in fiscal 1994,
   primarily due to an increase in the volume of soil processed at the
   Company's soil-remediation centers located in Southern California and
   Florida, additional revenues of $3.8 million from businesses acquired in
   late fiscal 1994 and in fiscal 1995 and, to a lesser extent, revenues
   generated from the Hanford contract. Revenues from laboratory-testing
   services, excluding the radiochemistry laboratory services included in
   remediation and recycling services, increased to $8.3 million in fiscal
   1995 from $6.0 million in fiscal 1994, primarily due to the inclusion of
   revenues from Terra Tech Labs, Inc. (Terra Tech), which was acquired in
   late fiscal 1994. Metal-treating revenues increased to $26.7 million in
   fiscal 1995 from $25.7 million in fiscal 1994, primarily due to the
   Company's efforts to increase its nongovernment business.

        Contract revenues from related party in fiscal 1994 represents funding
   under an agreement between the Company and Thermo Electron to fund up to
   $4.0 million of the direct and indirect costs of the Company's development
   of soil-remediation centers (Note 9). The Company earned no profit from
   this funding. As of October 2, 1993, funding under this agreement was
   completed. Any expenses incurred in connection with the development of
   additional soil-remediation centers subsequent to October 2, 1993, are
   included in product and new business development expenses in the
   accompanying statement of income.

   Fiscal 1995 Compared With Fiscal 1994 (continued)

        The gross profit margin increased to 26% in fiscal 1995 from 24% in
   fiscal 1994. The gross profit margin on consulting and design services
   improved to 25% in fiscal 1995 from 17% in fiscal 1994 due to the inclusion
   of higher-margin revenues at Killam, which was acquired in February 1995.
   The gross profit margin on remediation and recycling services declined
   slightly to 33% in fiscal 1995 from 34% in fiscal 1994, primarily due to a
   decrease in higher-margin radiochemistry laboratory revenues, offset in
   part by higher-margin revenues associated with the start-up of the Hanford
   contract. The gross profit margin on laboratory-testing services decreased
   to 23% in fiscal 1995 from 30% in fiscal 1994, primarily due to a decrease
   in higher-margin revenues and an increase in lower-margin revenues from
   Terra Tech. The gross profit margin on metal-treating revenues increased to
   14% in fiscal 1995 from 8% in fiscal 1994 as a result of the Company's
   efforts to increase nongovernment business. 

        Selling, general and administrative expenses as a percentage of
   revenues remained relatively unchanged at 19.6% in fiscal 1995, compared
   with 19.2% in fiscal 1994.

        The Company recorded gains on the issuance of stock by subsidiaries of
   $1.3 million in fiscal 1995 and $4.5 million in fiscal 1994 (Note 11).

        Net interest income was $0.5 million in fiscal 1995, compared with
   $0.6 million in fiscal 1994. An increase in interest expense due to
   borrowings from Thermo Electron in May 1994 to fund the Company's
   investment in the environmental services joint venture with Thermo
   Instrument and in February 1995 to fund the Company's acquisition of Killam
   Associates was offset in part by higher average invested balances.

        See Note 6 to the Consolidated Financial Statements for a
   reconciliation of the statutory tax rate to the effective tax rate.

   Liquidity and Capital Resources

        Consolidated working capital, including cash, cash equivalents, and
   short-term available-for-sale investments, increased to $67.4 million at
   March 30, 1996 from $64.7 million at April 1, 1995. Cash, cash equivalents,
   and short- and long-term available-for-sale investments were $40.3 million
   at March 30, 1996, compared with $51.5 million at April 1, 1995. In
   addition, at March 30, 1996, the Company had $24.3 million of long-term
   held-to-maturity investments, compared with $22.6 million at April 1, 1995.
   Of the $40.3 million balance at March 30, 1996, $35.3 million was held by
   Thermo Remediation, $0.1 million by Thermo EuroTech, and the remainder by
   the Company and its wholly owned subsidiaries. During fiscal 1996,
   operating activities provided cash of $8.5 million. The Company used cash
   of $5.4 million in fiscal 1996 to fund increases in inventory and unbilled
   contract costs and fees primarily due to increased thermal-processing
   equipment contracts and increased inventory at North Refinery, and used
   $5.2 million to reduce current liabilities.

   Operations (continued)

   Liquidity and Capital Resources (continued)

        During fiscal 1996, the Company expended an aggregate of $78.1
   million, net of cash acquired, to purchase Lancaster Laboratories, ReTec,
   and the businesses formerly operated by the Company's joint venture with
   Thermo Instrument. In addition, the Company expended $16.5 million on
   purchases of property, plant and equipment, primarily relating to two
   soil-remediation sites constructed in fiscal 1996.

        In May 1995, Thermo Remediation issued and sold $38 million principal
   amount of 4 7/8% subordinated convertible debentures due 2000. In addition,
   in May 1995, Thermo Remediation sold 500,000 shares of its common stock in
   a private placement for net proceeds of $6.6 million. In June 1995, Thermo
   Remediation repaid its $4.0 million note payable to Thermo Electron with
   proceeds from the offerings.

        In May 1996, the Company issued and sold $115 million principal amount
   of 4 5/8% subordinated convertible debentures due 2003. The debentures are
   convertible into shares of the Company's common stock at a price of $15.90
   per share. In May 1996, the Company repaid its $15.0 million and $35.0
   million notes payable to Thermo Electron with proceeds from the offering. 

        The Company has no material commitments to acquire other businesses or
   for capital expenditures. Such expenditures will largely be affected by the
   number and size of the complementary businesses that can be acquired or
   developed during the year. The Company believes that it has adequate
   resources to meet the financial needs of its current operations for the
   foreseeable future.
