                   Notes to Consolidated Financial Statements


   1.   General

        The interim consolidated financial statements presented have been
   prepared by Thermo TerraTech Inc. (the Company) without audit and, in the
   opinion of management, reflect all adjustments of a normal recurring nature
   necessary for a fair statement of the financial position at June 29, 1996,
   the results of operations for the three-month periods ended June 29, 1996
   and July 1, 1995, and the cash flows for the three-month periods ended June
   29, 1996 and July 1, 1995. Interim results are not necessarily indicative
   of results for a full year.

        The consolidated balance sheet presented as of March 30, 1996, has
   been derived from the consolidated financial statements that have been
   audited by the Company's independent public accountants. The consolidated
   financial statements and notes are presented as permitted by Form 10-Q and
   do not contain certain information included in the annual financial
   statements and notes of the Company. The consolidated financial statements
   and notes included herein should be read in conjunction with the financial
   statements and notes included in the Company's Annual Report on Form 10-K
   for the fiscal year ended March 30, 1996, filed with the Securities and
   Exchange Commission.

        Certain amounts in fiscal 1996 have been reclassified to conform to
   the fiscal 1997 financial statement presentation. Certain of these
   reclassifications are required to present consistent classification of
   expenses within the Company's consulting and design services business.

   2.   Subordinated Convertible Debentures

        In May 1996, the Company issued and sold $115.0 million principal
   amount of 4 5/8% subordinated convertible debentures due 2003 for net
   proceeds of $112.5 million. The debentures are convertible into shares of
   the Company's common stock at a price of $15.90 per share and are
   guaranteed on a subordinated basis by Thermo Electron Corporation (Thermo
   Electron). The Company has agreed to reimburse Thermo Electron in the event
   Thermo Electron is required to make a payment under the guarantee. In May
   1996, the Company repaid its $15.0 million and $35.0 million promissory
   notes to Thermo Electron with proceeds from the offering.


   Item 2 - 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, encompassing a range of specializations within the
   remediation and recycling, consulting and design, and laboratory-testing
   industries. The Company also provides metal-treating services and
   thermal-processing systems used to treat primary metals and metal parts.

                              THERMO TERRATECH INC.

   Overview (continued)

   The Company's environmental services businesses are affected by several
   factors, particularly, extreme weather variations, government spending, and
   regulation of remediation activities.

        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 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. 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
   addition, Thermo Remediation's Thermo Fluids subsidiary offers
   fluids-recycling services including waste motor oil and wastewater
   treatment throughout Arizona, Nevada, and in neighboring states. 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. Through
   its North Refinery subsidiary, Thermo Eurotech specializes in converting
   "off-spec" and contaminated petroleum fluids into usable oil products.

        Consulting and Design - The Company's wholly owned Killam Associates
   subsidiary provides environmental consulting and engineering services and
   specializes in wastewater treatment and water resources management. 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. 

        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) expanded 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.

   Results of Operations

   First Quarter Fiscal 1997 Compared With First Quarter Fiscal 1996

        Total revenues in the first quarter of fiscal 1997 increased 34% to
   $66.9 million from $49.9 million in the first quarter of fiscal 1996.
   Revenues from remediation and recycling services were $27.5 million in
   fiscal 1997, compared with $15.4 million in fiscal 1996, primarily due to
   the inclusion of $10.5 million in revenues from ReTec, which was acquired
   in December 1995, an increase in revenues at Thermo EuroTech and, to a
   lesser extent, higher revenues from a long-term environmental restoration
   contract for the U.S. Department of Energy's (DOE's) Hanford site (Hanford)
   and related health physics services. These increases were largely offset by
   a decrease in radiochemistry laboratory work, reflecting a reduction in
   spending at the DOE and delays in federal government budget appropriations.
   Revenues from soil-remediation services decreased 8% resulting from
   declines in the volume and price of soil processed due to competitive
   pricing pressures and ongoing regulatory uncertainties in several states.
   Revenues from consulting and design services increased to $21.5 million in
   fiscal 1997 from $19.8 million in fiscal 1996, primarily due to increased
   revenues from two major contracts, offset in part by lower revenues from
   federal government contracts, reflecting a reduction in spending and delays
   in budget appropriations. Revenues from laboratory-testing services,
   excluding the radiochemistry laboratory services included in remediation
   and recycling services, increased to $8.8 million in fiscal 1997 from $7.5
   million in fiscal 1996, largely due to the inclusion of an additional $2.8
   million of revenues from Lancaster Laboratories, acquired in May 1995,
   offset in part by a decline in revenues due to reduced federal spending.
   Metal-treating revenues increased to $9.1 million in fiscal 1997 from $7.2
   million in fiscal 1996, primarily due to an increase in demand for
   thermal-processing equipment.

        The gross profit margin decreased to 19% in the first quarter of
   fiscal 1997 from 24% in the first quarter of fiscal 1996, primarily due to
   the inclusion of lower-margin revenues from ReTec and a decrease in gross
   profit margins for remediation and recycling services due to competitive
   pricing pressures. These decreases were offset in part by higher gross
   profit margins from metal-treating services resulting from an increase in
   revenues.

        Selling, general and administrative expenses as a percentage of
   revenues decreased to 13% in the first quarter of fiscal 1997 from 17% in
   the first quarter of fiscal 1996, primarily due to efficiencies associated
   with an increase in revenues and a decline in expenses related to the
   consolidation of administrative functions within the consulting and design
   services business.

        Interest income increased to $1.6 million in the first quarter of
   fiscal 1997 from $1.4 million in the first quarter of fiscal 1996,
   primarily due to an increase in invested amounts as a result of the
   Company's May 1996 issuance of 4 5/8% subordinated convertible debentures
   (Note 2). Interest expense increased to $3.1 million in fiscal 1997 from
   $2.3 million in fiscal 1996, primarily due to the Company's May 1996
   issuance of subordinated convertible debentures and Thermo Remediation's

                              THERMO TERRATECH INC.

   First Quarter Fiscal 1997 Compared With First Quarter Fiscal 1996
   (continued)

   May 1995 issuance of 4 7/8% subordinated convertible debentures, offset in
   part by a decrease in interest expense due to the repayment of promissory
   notes to Thermo Electron Corporation (Thermo Electron) with proceeds from
   the Company's May 1996 issuance of subordinated convertible debentures
   (Note 2).

        Equity in earnings of unconsolidated subsidiary in the first quarter
   of fiscal 1997 represents ReTec's proportionate share of income from a
   joint venture.

        During the first quarter of fiscal 1996, the Company recorded gains of
   $2.7 million from the sale of stock by subsidiary.

        The effective tax rates were 47% and 19% in the first quarter of
   fiscal 1997 and 1996, respectively. The effective tax rate in fiscal 1997
   was higher than the statutory federal income tax rate primarily due to
   nondeductible amortization of cost in excess of net assets of acquired
   companies and the impact of state income taxes. The effective tax rate in
   fiscal 1996 was lower than the statutory federal income tax rate primarily
   due to the nontaxable gain on issuance of stock by subsidiary. 

        Minority interest expense decreased to $0.2 million in the first
   quarter of fiscal 1997 from $0.4 million in the first quarter of fiscal
   1996, due to a reduction in earnings from the Company's majority-owned
   subsidiaries.

   Liquidity and Capital Resources

        Consolidated working capital, including cash, cash equivalents, and
   short-term available-for-sale investments, increased to $106.3 million at
   June 29, 1996 from $67.4 million at March 30, 1996. Cash, cash equivalents,
   and short- and long-term available-for-sale investments were $101.5 million
   at June 29, 1996, compared with $40.3 million at March 30, 1996. Of the
   $101.5 million balance at March 30, 1996, $33.7 million was held by Thermo
   Remediation and the remainder by the Company and its wholly owned
   subsidiaries. In addition, at June 29, 1996 the Company had $24.7 million
   of long-term held-to-maturity investments, compared with $24.3 million at
   March 30, 1996. During the first quarter of fiscal 1997, $3.2 million of
   cash was provided by operating activities. In the first quarter of fiscal
   1997, the Company used cash of $3.0 million primarily to fund an increase
   in unbilled contract costs and fees due to an increase in thermal-
   processing equipment contracts, an increase in remediation contracts at
   ReTec, as well as an increase in consulting and design services contracts.

        In May 1996, the Company issued and sold $115.0 million principal
   amount of 4 5/8% subordinated convertible debentures due 2003 for net
   proceeds of $112.5 million (Note 2). The 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. In May 1996, the Company repaid its $15.0 million and
   $35.0 million promissory notes to Thermo Electron with proceeds from the
   offering.

   Liquidity and Capital Resources (continued)

        In the first quarter of fiscal 1997, the Company expended $4.4 million
   on purchases of property, plant and equipment. During the remainder of
   fiscal 1997, the Company expects to expend $5.6 million for purchases of
   property, plant and equipment. The Company has no material commitments for
   the acquisition of 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.

                        ELSON T. KILLAM ASSOCIATES, INC.
                        1987 INCENTIVE STOCK OPTION PLAN


        1.   Purpose

             The Elson T. Killam Associates, Inc. 1987 Incentive Stock
        Option Plan (the "Plan") is intended to enable Elson T. Killam,
        Associates, Inc. (the "Company") and any parent or subsidiary
        corporation of the Company to attract and retain capable officers
        and key senior management employees and to provide them with
        incentives to promote the best interests of the Company and its
        parent and subsidiaries by enabling and encouraging them, through
        the grant of incentive stock options (the "Options") to acquire
        Company stock.

             As used in the Plan, the term "incentive stock options"
        means options which are intended to qualify as incentive stock
        options within the meaning of section 422A of the Internal
        Revenue Code of 1986, as amended from time to time (the "Code"),
        and which are designated as incentive stock options in the Option
        Agreement.  The term "subsidiary" means any corporation (whether
        or not in existence at the time the Plan is adopted) which, at
        the time an Option is granted is a subsidiary of the Company
        under the definition of "subsidiary corporation" contained in
        section 425(f) of the Code, or any similar provision hereafter
        enacted.  The term "parent" means any corporation (whether or not
        in existence at the time the Plan is adopted) which, at the time
        an Option is granted, is a parent of the Company under the
        definition of "parent corporation" contained in section 425(e) of
        the Code or any similar provision hereafter enacted.  The term
        "related corporation" means any corporation which is a subsidiary
        or parent of the Company.

        2.   Administration.

             Except as otherwise provided below, the Plan shall be
        administered by a Management Committee (the "Committee") which
        shall be composed of the President of Les Chantiers Modernes and
        the President of the Company or their representatives designated
        in writing.  Subject to the terms of the Plan, the Committee
        shall have the authority to determine the persons to whom
        incentive stock options shall be granted under the Plan and to
        recommend the date of grant and the other terms and conditions
        thereof.  The Committee shall have full authority to administer
        the Plan and all references hereinafter shall be made to the
        actions of the Committee except as otherwise provided.  The
        Committee shall have the authority to establish, from time to
        time, such rules and regulations, not inconsistent with the
        provisions of the Plan, for the proper administration of the
        Plan, and to make such determinations and interpretations under
        or in connection with the Plan and the Options granted hereunder,
        as it deems necessary or advisable.  All such rules, regulations,
        determinations and interpretations shall be binding and

                                        1PAGE
<PAGE>
        conclusive upon the Company, its stockholders, employees
        (including former employees), and any related corporation, and
        upon their respective legal representatives, beneficiaries,
        successors and assigns and upon all other persons claiming under
        or through any of them.  No member of the of the Committee shall
        be liable for any action or determination made in good faith with
        respect to the Plan or any Option granted hereunder.

        3.   Eligibility.

             The persons eligible to participate in the Plan shall be the
        officers and key senior management employees of the Company and
        related corporations who may be designated by the Committee.  The
        persons eligible to receive Options under the Plan are
        hereinafter referred to as "Eligible Individuals".

        4.   Stock Subject to the Plan.

             Subject to the provisions of Section 7 hereof, 2,130 shares
        (the "Shares") of ten dollars ($10.00) par value common stock of
        the Company (the "Common Stock"), shall be available for the
        grant of Options under the Plan.  Shares issuable under the Plan
        shall be authorized but unissued Shares or reacquired Shares of
        the Company as determined by the Committee.

             If any Option granted under the Plan expires or otherwise
        terminates, in whole or in part, without having been exercised,
        the Shares subject to the unexercised portion of such Option
        shall be available for the granting of Options under the Plan as
        fully as if such Shares had never been subject to an Option.

        5.   Grants, Terms and Conditions of Options.

             From time to time until the expiration or earlier
        termination of the Plan, the Committee may grant Options to
        Eligible Individuals (such grantees are hereinafter referred to
        as "Optionees"), under the Plan.  Options granted pursuant to the
        Plan to such Eligible Individuals shall be in such form as the
        Committee shall from time to time approve, and shall be subject
        to the following terms and conditions to the extent such terms
        and conditions are applicable to such Option:

             (a) Price.  The option price per Share under each Option
                  granted under the Plan as an incentive stock option
                  shall be determined and fixed by the Committee, in its
                  discretion, but shall not be less than the fair market
                  value of the Shares on the date of grant of such
                  Option.  The fair market value of a Share on any day
                  shall mean (i) the value assigned to each Share in
                  accordance with the valuation method attached hereto as
                  Exhibit A; or (ii) such other method of determining
                  fair market value as may be required by the Code or the
                  regulations and rulings thereunder, and adopted by the
                  Committee from time to time.

                  Subsections (c) through (g) below and in Section 7
                  hereof, and except as otherwise provided in Subsection
                  (j) below, the duration of each Option shall not be
                  more than ten (10) years from the date of grant.

             (c) Exercise and Payment. Options shall be exercisable in
                  such installments and on such dates as the Committee
                  may specify provided; however, that no Options may be
                  exercised until July 1, 1991, except as otherwise
                  provided in accordance with Section 7 or in the event
                  of death, disability, involuntary termination without
                  cause or retirement of an Optionee as provided herein.
                  Options shall be exercisable in accordance with the
                  following schedule:

                 Option
                 Grant Period                  Exercisable
                 ------------                  -----------

                 January 1 to                  4 years after
                 December 31,1987              Date of Grant

                 January 1, 1988               25% exercis-
                 and thereafter                able as of the
                                                anniversary date
                                                of each Date of
                                                Grant beginning in
                                                or after 1991

                 Except as otherwise provided in Subsections (d) through
                  (g) below, Options shall only be exercisable by an
                  Optionee while he remains in the employ of the Company
                  or a related corporation.  Any Option Shares, the right
                  to the purchase of which has accrued, may be purchased
                  at any time up to the expiration or termination of the
                  Option.  As a condition to the exercise of any of the
                  Options, each Optionee shall enter into a Shareholders'
                  Agreement in substantially the same form as attached
                  hereto as Exhibit D. Options may be exercised, in whole
                  or in part, from time to time, by giving written notice
                  of exercise to the Company at its principal office,
                  specifying the number of Shares to be purchased, and
                  accompanied by payment in full of the aggregate
                  purchase price for such Shares or by a promissory note
                  executed in the form attached hereto as Exhibit C. Only
                  full Shares shall be delivered, and any fractional
                  Share which might otherwise be deliverable upon
                  exercise of an Option granted hereunder shall be
                  forfeited.

                 The purchase price shall be payable in cash or its
                  equivalent, as determined by the Committee, in its
                  discretion unless an Optionee requests the Company to

                                        3PAGE
<PAGE>
                  permit the exercise of any or all Options by delivery
                  of a promissory note in accordance with Section 8
                  hereof.

             (d) Termination of Optionee's Employment. If an Optionee's
                  employment with the Company and all related
                  corporations is terminated for any reason, voluntarily
                  or with cause, other than by reason of death,
                  disability, or retirement (as described in Subsections
                  (e), (f) and (g) below) prior to the expiration of the
                  original term of his Option ("Expiration Date") such
                  Option shall terminate immediately upon such
                  termination of employment and all rights with respect
                  to any unvested or unexercised Options shall be
                  forfeited.  For purposes of this Subsection, an
                  Optionee's employment relationship shall not be deemed
                  terminated while the Optionee is on military leave,
                  sick leave, or other bona fide leave of absence (such
                  as temporary employment by the government) if the
                  period of such leave does not exceed ninety (90) days,
                  or, if longer, so long as the Optionee's right to
                  reemployment with the Company or a related corporation
                  is guaranteed either by statute or contract.

             (e) Death of Optionee.  If an Optionee's employment is
                  terminated by reason of his death prior to the
                  Expiration Date of his Option, or if an Optionee whose
                  employment is terminated as a result of retirement or
                  disability (as described in Subsections (f) and (g)
                  below) shall die following his termination of
                  employment but prior to the Expiration Date of his
                  Option or expiration of the period determined under
                  Subsections (f) or (g) below, if earlier, such Option
                  may be exercised by the Optionee's estate, personal
                  representative or beneficiary who acquired the right to
                  exercise such Option by bequest or inheritance or by
                  reason of the death of the Optionee, whether or not the
                  Options were completely exercisable under Section 5 (c)
                  at the time of death, at any time prior to the earlier
                  of (i) three (3) months following the date of the
                  Optionee's death, or (ii) the Expiration Date of such
                  Option (which, in the case of death following a
                  termination of employment pursuant to Subsections (f)
                  or (g) below, shall be deemed to mean the expiration of
                  the exercise period determined thereunder).

             (f) Disability of Optionee.  If an Optionee shall become
                  disabled (within the meaning of section 22(e)(3) of the
                  Code) during his employment with the Company or a
                  related corporation, and his employment with the
                  Company and all related corporations is terminated as a
                  consequence of such disability prior to the Expiration
                  Date of his Option, such Option may be exercised in
                  full by the Optionee, whether or not the Options were

                                        4PAGE
<PAGE>
                  completely exercisable under Section 5(c) at the time
                  of such disability, at any time prior to the earlier of
                  (i) three (3) months following the date of the
                  Optionee's termination of employment, or (ii) the
                  Expiration Date of such Option.  In the event of the
                  Optionee's legal disability such Option may be so
                  exercised by the Optionee's legal representative.

             (g) Retirement or Involuntary Termination of Optionee. If
                  an Optionee retires in accordance with the retirement
                  policy of the Company or any related corporation, or
                  otherwise involuntarily has his employment terminated
                  by the Company without cause prior to the Expiration
                  Date of his Option, all Options may be exercised in
                  full by the Optionee, whether or not the Options were
                  completely exercisable under Section 5(c) at the time
                  of such retirement or involuntary termination any time
                  prior to the earlier of (i) three (3) months after the
                  date of retirement or (ii) the Expiration Date of such
                  Option.

             (h) Transferability. No Option shall be assignable or
                  transferable by an Optionee otherwise than by will or
                  by the laws of descent and distribution, and during the
                  lifetime of the Optionee, the Option shall be
                  exercisable only by him, or in the event of his legal
                  disability, by his legal representative.

             (i) Rights as a Stockholder.  An Optionee shall have no
                  rights as a stockholder with respect to any Shares
                  covered by his Option until the issuance of a stock
                  certificate to him representing such Shares.

             (j) Ten Percent Shareholder.  Any other provision of the
                  Plan notwithstanding, if an Eligible Individual owns
                  more than ten percent (10%) of the total combined
                  voting power of all shares of stock of the Company or
                  of a related corporation at the time an incentive stock
                  Option is granted to such Eligible Individual, the
                  incentive stock option price shall not be less than one
                  hundred ten percent (110%) of the fair market value of
                  the optioned Shares on the date the incentive stock
                  option is granted, and such incentive stock option by
                  its terms shall not be exercisable after the expiration
                  of five (5) years from the date the incentive stock
                  option is granted.  For purposes of this Subsection, an
                  Eligible Individual shall be considered to own any 

                                        5PAGE
<PAGE>
                  shares of the Company or a related corporation which
                  are attributable to such Eligible Individual under
                  section 425(d) of the Code.

             (k) Annual Limit on Grant of Incentive Stock Options.  The
                  aggregate fair market value (determined as of the time
                  an incentive stock option is granted) of the Shares
                  with respect to which incentive stock options are
                  exercisable for the first time by an Optionee during
                  any calendar year (under the Plan and any other
                  incentive stock option plan of the Company or a related
                  corporation) shall not exceed one hundred thousand
                  dollars ($100,000.00).

             (l) Option Agreement and Further Conditions.  As a
                  condition to the grant of an Option, each Optionee
                  shall enter into, and be bound by the terms of, a stock
                  option agreement (the "Option Agreement") which shall
                  state the number of Shares to which the Option
                  pertains.  The Option Agreement shall set forth such
                  terms, conditions and restrictions regarding the Option
                  not inconsistent with the Plan and the provisions of
                  section 422A(b) of the Code as the Committee shall
                  determine.  Without limiting the generality of the
                  foregoing, the Committee, in its discretion, may impose
                  further conditions upon the exercisability of Options
                  and restrictions on transferability with respect to
                  Shares issued upon exercise of Options.

             (m) Withholding.  The obligation of the Company to deliver
                  Shares upon the exercise of any Option shall be subject
                  to any applicable federal, state and local tax
                  withholding requirements.

        6.   Listing and Registration of Shares.

             Each Option under the Plan shall be subject to the
        requirement that, if at any time the Committee shall determine in
        its discretion that the listing, registration or qualification of
        the Shares covered thereby upon any securities exchange or under
        the laws of any jurisdiction, or the consent or approval of any
        regulatory body, is necessary or desirable as a condition of, or
        in connection with, the granting of such Option, or the
        acquisition of Shares thereunder, or that action by the Company
        or the Optionee should be taken in order to obtain an exemption
        from any such requirement, then no such Option may be exercised
        in whole or in part and no certificate representing Shares shall
        be issued unless and until such listing, registration,
        qualification, consent, approval, or action shall have been
        effected, obtained, or taken on conditions acceptable to the
        Committee.  Each Optionee or his legal representative or
        beneficiaries, also may be required to give satisfactory
        assurance that Shares acquired upon exercise of an Option are
        being acquired for investment and not with a view to

                                        6PAGE
<PAGE>
        distribution, and certificates representing such Shares may be
        legended accordingly.  Such Shares shall be transferable
        thereafter only if the proposed transfer is permissible under the
        Plan and the Option Agreement and if, in the opinion of counsel
        (who shall be satisfactory to the Company), such transfer shall
        at such time be in compliance with securities laws.  Nothing
        contained in this Section 6 shall obligate the Company to list,
        register or qualify any of the Shares.

        7.   Adjustments.

             The number of Shares which may be issued under the Plan, as
        stated in Section 4 hereof, and the number of Shares issuable
        upon exercise of outstanding Options under the Plan (as well as
        the exercise price per share under such outstanding Options)
        shall be equitably adjusted by the Committee to reflect any stock
        dividend, stock split, share combination, or similar change in
        the capitalization of the Company.

             In the event the Company is liquidated, its shares become
        publicly traded, or a corporate transaction described in section
        425(a) of the Code and the Treasury Regulations issued thereunder
        occurs (as, for example, a merger, consolidation, acquisition of
        property or stock, separation, or reorganization), each
        outstanding Option shall be immediately exercisable in full
        regardless of any exercise schedule otherwise applicable.  The
        Committee shall give each Optionee to whom an outstanding Option
        has been granted, sixty (60) days written notice prior to such
        transaction (i.e., by reason of such liquidation, sale, or other
        corporate transaction described above), so that any outstanding
        Option or portion thereof may be exercised up to, and including
        the earlier of: (i) the date immediately preceding such
        transaction, or (ii) the Expiration Date of such Option.  In such
        event, the Committee may, in its sole discretion, allow each such
        Optionee to exercise his Option in full or in part (if it has not
        otherwise terminated) regardless of the provisions of Section
        5(c) hereof or of the terms of any Option Agreement even if under
        the Plan or the Incentive Stock Option Agreement the vesting
        period has not expired with respect to such Shares.  The
        Committee, in its discretion, may change the number of Shares
        issuable upon exercise of outstanding Options (as well as the
        exercise price per share under such outstanding Options) to
        equitably reflect any such corporate transaction, provided that
        any such change is made in accordance with section 425(a) of the
        Code.

        8.   Loans to Eligible Employees.

             Prior to delivery of a written notice of exercise (under
        Section 5 (c)), the Optionee may obtain a loan or loans from the
        Company for the purchase of Shares by delivering a written
        request to the Committee stating the desired amount of the loan.
        Loan requests may not be submitted for amounts in excess of
        ninety percent (90%) of the exercise price.  If such request

                                        7PAGE
<PAGE>
        comports with the requirements of this Plan, the Committee shall
        notify the Optionee within seven (7) days of receipt of the loan
        request that the loan is approved, subject to the conditions set
        forth in Section 8 hereof and the other applicable provisions of
        this Plan.

             (a) The loan will be extended only if, within thirty (30)
                  days after receipt from the Committee of notice that
                  the loan request is approved, the Optionee exercises an
                  Option granted pursuant to this Plan for the purchase
                  from the Company of a number of Shares which in the
                  aggregate have an exercise price at least equal to the
                  amount of the loan requested and approved.

             (b) Loans will be extended under this Plan only to persons
                  who are employees an the date the Option referred to in
                  Section 8(a) is exercised, and no loans will be
                  extended in connection with Options exercised in
                  connection with death, disability or retirement.

             (c) The loan shall be evidenced by a promissory note
                  bearing interest at the minimum rate to avoid the
                  imputation of interest under the Code in substantially
                  the same form as attached hereto as Exhibit C.

             (d) If an Optionee terminates his employment with the
                  Company or any subsidiary corporation due to death,
                  disability, retirement, voluntary or involuntary
                  termination or otherwise, any loan indebtedness, and
                  interest thereon, outstanding an the date of such
                  termination shall be repaid to the Company, in full,
                  within ninety (90) days of such termination.

             (e) As security for the repayment of the loan extended
                  under this Plan, the Optionee shall pledge to the
                  Company shares of Stock of the Company having a total
                  fair market value equal to one hundred percent (100%)
                  of the loan amount; provided, however, that to the
                  extend such Shares are subject to the provisions of
                  Section 12, alternative security may be required within
                  the discretion of the Committee.

             (f) The Company shall be entitled to all the rights and
                  remedies with respect to the pledged Shares of a
                  secured creditor under the Uniform Commercial Code as
                  in effect from time to time in the State of New Jersey.
                  If an Optionee, or his personal representative or
                  legatee, as the case may be, fails to pay any
                  indebtedness when due or within twenty (20) days
                  thereafter, without making other arrangements
                  satisfactory to the Committee for discharging his
                  indebtedness, the Company may sell any pledged stock or
                  property at public or private sale and apply the
                  proceeds to the unpaid indebtedness without demand or

                                        8PAGE
<PAGE>
                  notice to the Optionee.

             (g) If the Optionee is entitled to receive any Special
                  Performance Bonus in accordance with Exhibit B hereto,
                  such amounts must be applied to repay any loan which
                  remains outstanding at the time such bonus is paid or
                  is to be paid.

        9.   Amendment or Discontinuance of the Plan.

             The Board at any time, and from time to time, may suspend or
        discontinue the Plan or amend it in any respect whatsoever,
        provided, however, that, without the approval of the holders of
        at least two-thirds (2/3) of the outstanding Shares, the Plan may
        not be amended so as to materially (a) increase the benefits
        accruing to participants under the Plan, (b) increase the number
        of Shares which may be issued under the Plan (except for
        adjustments permitted or required under Section 7 hereof), (c)
        modify the requirements as to eligibility for participation in
        the Plan, or (d) increase the cost of the Plan to the Company;
        and provided further, that no such suspension, discontinuance or
        amendment shall materially impair the rights of any holder of an
        outstanding Option without the consent of such holder.

        10.  Absence of Rights.

             The recommendation or selection of an Eligible Individual as
        a recipient of an Option under the Plan shall not entitle such
        person to any Option unless and until the grant actually has been
        made by appropriate action of the Committee; and any such grant
        is subject to the provisions of the Plan.  Further, the granting
        of an Option to a person shall not entitle that person to
        continued employment by the Company or a related corporation or
        affect the terms and conditions of such employment, and the
        Company shall have the absolute right, in its discretion, to
        retire such person in accordance with its retirement policies or
        otherwise to terminate his employment, whether or not such
        termination may result in a partial or total termination of his
        Option.

        11.  Application of Funds.

             The funds received by the Company upon the exercise of
        Options and otherwise under the Plan shall be used for general
        corporate purposes as permitted by law.

        12.  Pledge of Shares.

             To the extent required under Section 12 (u) of the Revolving
        Credit and Term Loan Agreement dated as of September 16, 1986, to
        which the Company is a party, the Company shall not issue Shares
        pursuant to the exercise of any Options unless the Optionee shall
        have entered into a Pledge Agreement, substantially in the Form
        of Exhibit E as attached hereto (except that the rights of the

                                        9PAGE
<PAGE>
        Banks and the Agents, as such persons are defined in such Pledge
        Agreement, shall have recourse only to the being pledged),
        pledging the Shares the Optionee is purchasing to the Agent.

        13.  Shareholder Approval.

             This Plan is subject to the approval of the holders of at
        least two-thirds (2/3) of the outstanding Shares, which approval
        shall be obtained on or before December 15, 1988, which date is
        within twelve (12) months of the date the Plan is adopted by the
        Board of Directors of the Company.  If the shareholders shall not
        approve the Plan as aforesaid, the Plan shall not be effective,
        and any and all actions taken prior thereto shall be null and
        void or shall, if necessary, be deemed to have been fully
        rescinded.

        14.  No Obligation to Exercise Option.

             The granting of an Option shall impose no obligation upon an
        Optionee to exercise such Option.

        15.  Termination of Plan.

             No Options or Stock Grants may be granted after December 15,
        1997, provided, however, that the Plan and all outstanding
        Options shall remain in effect until such Options have expired or
        vested, as the case may be, or are terminated in accordance with
        the Plan.



                                                            EXHIBIT 10.2

                        ELSON T. KILLAM ASSOCIATES, INC.
                        1987 INCENTIVE STOCK OPTION PLAN
                        INCENTIVE STOCK OPTION AGREEMENT

             INCENTIVE STOCK OPTION AGREEMENT, dated as of the ____ day
       of _________ 198_ (the "Grant Date") between Elson T. Killam
       Associates, Inc., a New Jersey Corporation (the "Company") and
       __________ (the "Optionee"), a key senior management employee or
       officer of the Company.

             WHEREAS, the Company desires to afford the optionee an
       opportunity to purchase shares of              dollar ($   ) par
       value Common Stock, of the Company ("Shares") as hereinafter
       provided, in accordance with the provisions of Elson T. Killam
       Associates, Inc. 1987 Incentive Stock Option Plan (the "Plan"), a
       copy of which is attached hereto.

             NOW, THEREFORE, in consideration of the mutual covenants
       hereinafter set forth and for other good and valuable
       consideration the legal sufficiency of which is hereby
       acknowledged, the parties hereto, intending to be legally bound
       hereunder, agree as follows:

             1.   Grant of Option.  The Company hereby grants to the
       Optionee the right and option to purchase all or any part of an
       aggregate of __________ Shares (the "Option"), which Option is
       intended to qualify as an incentive stock option under Section
       422A of the Internal Revenue Code of 1986 (the "Code").  The
       Option is in all respects limited and conditioned as hereinafter
       provided, and is subject in all respects to the Plan's terms and
       conditions as they may be amended from time to time in accordance
       with the Plan (which terms and conditions are and automatically
       shall be incorporated herein by reference and made a part hereof
       and shall control in the event of any conflict with any other
       terms of this Agreement).

             The Option is granted subject to the approval of the Plan
       on or before December 15, 1988 by the holders of at least
       two-thirds (2/3) of the outstanding Shares.  If said shareholder
       approval is not obtained as aforesaid, the Plan, this Agreement,
       and any and all actions (including without limitation the
       granting and exercise of the Option) taken pursuant to or in
       connection with either, shall be null and void or shall, if
       necessary, be deemed to have been fully rescinded.

             2.   Purchase Price.  The purchase price per share (the
       "Option Price") of the Shares covered by the Option (the "Option
       Shares") shall be $_____. It is the determination of the
       Committee that the Option Price is not less than one hundred
       percent (100%) of the fair market value of the Option Shares on
       the Grant Date.
PAGE
<PAGE>
             3.   Term.  Unless earlier terminated pursuant to any
       provision hereof or of the Plan, the Option shall expire on
       __________ (the "Expiration Date").

             4.   Exercise of Option.  The Option shall become
       exercisable on _____________, which date is four (4) years after
       the Grant Date if granted prior to 1988 or is exercisable in four
       (4) installments beginning on the anniversary of the Grant Date
       occurring in or after 1991 and each anniversary date thereafter.
       The right of the Optionee to purchase the Option Shares which are
       the subject of any installment of the Option which has become
       exercisable may be exercised in whole or in part at any time or
       times prior to the expiration or other termination of the Option.

             The foregoing provisions of this Paragraph 4
       notwithstanding, the exercisability of the Option is subject to
       the terms and conditions of the Plan, including those set forth
       in subsections (c) through (g) of Section 5 thereof.

             5.   Method of Exercising Option.  Subject to the terms and
       conditions of this Agreement and the Plan, the Option may be
       exercised by written notice to the Company at its principal
       office, which is presently located at 27 Bleeker Street, Post
       Office Box 1008, Millburn, New Jersey 08873.  Such notice (a
       suggested form of which is attached hereto) shall state the
       election to exercise the Option and the number of Option Shares
       with respect to which it is being exercised; shall be signed by
       the person or persons so exercising the Option; shall, if the
       Company so requests, be accompanied by the investment certificate
       referred to in Section 6 of the Plan; and shall be accompanied by
       payment of the full Option Price of such Option Shares unless a
       loan is permitted within the discretion of the Committee and in
       accordance with the Plan.  The Option Price shall be paid in
       cash, check, bank draft or postal or express money order, except
       to the extent a loan is otherwise permitted.  Upon receipt of
       such notice and payment, the Company, as promptly as practicable
       shall deliver or cause to be delivered a certificate or
       certificates representing the Shares with respect to which the
       Option is so exercised.  The certificate or certificates for such
       Shares shall be registered in the name of the person or persons
       so exercising the Option (or, if the Option is exercised by the
       Optionee and if the Optionee shall so request in the notice
       exercising the Option, shall be registered in the name of the
       Optionee and his or her spouse, jointly, with right of
       survivorship) and shall be delivered as provided above to or upon
       the written order of the person or persons exercising the Option.
       In the event the Option shall be exercised by any person or
       persons after the death or legal disability of the Optionee, such
       notice shall be accompanied by appropriate proof of the right of
       such person or persons to exercise the Option.  All Shares that
       shall be purchased upon the exercise of the Option as provided
       herein shall be fully paid and nonassessable by the Company.

             6.   Non-Transferability of Option.  The Option is not
PAGE
<PAGE>
       assignable or transferable, in whole or in part, by the Optionee,
       otherwise than by will or by the laws of descent and
       distribution.  During the lifetime of the Optionee, the Option
       shall be exercisable only by the Optionee or, in the event of
       legal disability, by the Optionee's legal representative.

             7.   Disqualifying Disposition of Option Shares.  The
       Optionee agrees to give written notice to the Company, at its
       principal office, if a "disposition"' of the Shares acquired
       through exercise of the Option granted hereunder occurs at any
       time within two (2) years after the Grant Date or within one (1)
       year after the transfer to the Optionee of such Shares.  For
       purposes of this Paragraph, the term "disposition" shall have the
       meaning assigned to such term by section 425(c) of the Code.

             8.   Withholding of Taxes.  The obligation of the Company
       to deliver Shares upon the exercise of the Option shall be
       subject to applicable Federal, state and local tax withholding
       requirements.

             9.   Governing Law.  This Agreement shall, to the maximum
       extent possible, be construed in a manner consistent with the
       Code provisions concerning incentive stock options, and its
       interpretation shall otherwise be governed by the laws of the
       State of New Jersey.

             IN WITNESS WHEREOF, the Company has caused this Incentive
       Stock Option Agreement to be executed by a duly authorized
       officer, and the Optionee has hereunto set his hand and seal, all
       as of the day and year first above written.

             WHEREAS, the Shareholders will have the right to purchase an

             WHEREAS, Killam, ETK and the Shareholders believe it is in

        may sell or transfer their Shares.

             NOW, THEREFORE, in consideration of the mutual covenants and
        promises contained in this Agreement, and for other good and
        valuable consideration, the receipt of which is acknowledged, the

        the number of Shares being purchased pursuant to this Agreement
        times the value per share determined pursuant to Article 7.

        employment with Killam or Duncan, as the case may be, (other than

             1.9  "Selling Shareholder" shall mean the Shareholder or the
        estate or legal representative of a Shareholder required to sell

                          ISSUED AND OUTSTANDING SHARES

             2.1  Ownership Of Shares.  As of the date of this Agreement,
        the Shareholders are the owners of the number of Shares, or
        options to purchase Shares, listed on Schedule 1.

             2.2  Future Shares.  The Shareholders agree to be bound by
        this Agreement with respect to the Shares now owned by them and
        any Shares acquired by them on or after the date of this
        Agreement (including but not limited to acquisition by purchase,
        gift, stock dividend, stock split or division, exercise of an
        option or options under the ISO Plan, or any other issuance to

                        USE OF SHARES PURCHASED BY KILLAM

        Group or other key employees of either Killam or Duncan, as
        designated from time to time by ETK, in amounts aggregating up to
        twenty percent (20%) of the ownership interest in Killam.  The
        time and individual amounts of such options shall be granted
        within the discretion of ETK.  To the extent any Shares are
        purchased by ETK, ETK may make such Shares available for
        redemption by Killam in order to facilitate the issuance of
        additional options in accordance with this Article.
        Alternatively, Killam and ETK may provide that a comparable
        amount of authorized but unissued Shares shall be made available
        for the issuance of options in accordance with this Article.


                                    ARTICLE 4

<PAGE>
                          VOLUNTARY TRANSFER OF SHARES

             4.1  Restriction on Transfer.  Except as otherwise provided
        herein, the Shareholders may not transfer any part of, or all of
        their Shares, whether now owned or hereafter acquired, in any
        manner whatsoever, to any third party.

             4.2  Notice of Intent to Transfer Shares.  In the event that
        a Shareholder (the "Selling Shareholder") desires to dispose of
        any or all of his Shares during his employment, and he obtains a
        bona fide written offer from any member or members of the
        Management Group to purchase the Shares (a "Bona Fide Offer"), he
        shall first give at least forty-five (45) days written notice
        (the "Exercise Period") to Killam of his desire to sell such
        shares.  Such notice shall state the number of Shares offered for
        sale (the "Offered Shares") and the offered purchase price (the
        "Offered Price").

             4.3  Option of Killam to Purchase Shares.  Within said
        Exercise Period, Killam shall have the option to purchase any or
        all of the Offered Shares as it determines, within its
        discretion.  If Killam elects to exercise its option to purchase
        any portion of the Offered Shares, written notice of such
        election to exercise its option shall be sent to the Selling
        Shareholder prior to the expiration of the Exercise Period.  The
        purchase price for any Shares sold hereunder shall be equal to
        the purchase price determined in accordance with Article 7
        regardless of whether the purchase price determined under Article
        7 is greater or less than the Offered Price.  The Closing for
        such Offered Shares shall occur within thirty (30) days after the
        notice, if any, accepting the purchase is received by the Selling
        Shareholder.

             4.4  Option of ETK to Purchase Shares.  If Killam does not
        elect to purchase any of the Offered Shares or elects to purchase
        less than all of the Offered Shares, it shall give written notice
        thereof to ETK during the Exercise Period, specifying the number
        of remaining Offered Shares.  ETK shall have the right to
        purchase all or part of the remaining Offered Shares by giving
        written notice to the Selling Shareholder within ten (10) days
        after receipt of the notice from Killam.  The purchase price for
        any Shares sold hereunder shall be equal to the purchase price
        determined in accordance with Article 7 regardless of whether the
        purchase price determined under Article 7 is greater or less than
        the Offered Price.

             4.5  Option of Management Group to Purchase Shares.  If ETK
        does not elect to purchase any of the remaining Offered Shares or
        elects to purchase some but not all of the remaining Offered
        Shares, ETK shall give written notice thereof to the Management
        Group, specifying the number of remaining Offered Shares.  Each
        member of the Management Group shall have the option to purchase
        any remaining Offered Shares in proportion with the number of
        Shares owned by such member in relation to the total number of

                                        4PAGE
<PAGE>
        Shares then owned by all members of the Management Group who
        desire to purchase any remaining Shares.  Each member shall
        exercise his option to purchase such Shares by giving notice to
        the Selling Shareholder within ten (10) days after receipt of the
        notice from ETK.  Such purchases shall be made by the Management
        Group at the price and on the terms of the Bona Fide Offer.  Any
        Offered Shares not purchased by Killam, ETK or the members of the
        Management Group may be sold to the member or members of the
        Management Group that made the Bona Fide Offer.


                                    ARTICLE 5
                         INVOLUNTARY TRANSFER OF SHARES

             5.1  Death.  Upon the death of a Shareholder, Killam or ETK,
        as determined by the companies, shall purchase and the estate or
        personal representative of the deceased Shareholder shall sell
        all of the Shares of Killam owned by the deceased Shareholder or
        any Shares thereafter acquired under the ISO Plan.  The Closing
        for such purchases, shall take place as soon as reasonably
        possible after the date of death of the deceased Shareholder in
        accordance with Section 1.1.

             5.2  Disability Of Shareholder.  In the event that a
        Shareholder shall become Disabled, Killam or ETK, as determined
        by the companies, shall purchase and the Shareholder, or legal
        guardian of the Disabled Shareholder, shall sell all of the
        Shares of Killam owned by the Disabled Shareholder or any Shares
        thereafter acquired under the ISO Plan.  The Closing for such
        purchase shall take place in accordance with Section 1.1.

             5.3  Involuntary Termination of Employment.  If any
        Shareholder ceases to be employed by Killam, or any Related
        Corporation, on account of an involuntary termination, Killam or
        ETK, as determined by the companies, shall purchase and the
        Shareholder shall sell, at the Closing, those Shares of Killam
        held by him at the time of his termination of employment or any
        Shares thereafter acquired under the ISO Plan.

             5.4  Voluntary Termination of Employment.

                  (a)  If any Shareholder ceases to be employed by
        Killam, or any Related Corporation, on account of a voluntary
        termination, Killam may, within its discretion, purchase those
        Shares held by the Shareholder at the time of his termination or
        any Shares thereafter acquired under the ISO Plan.  If Killam
        elects to purchase any or all of such Shares, the Shareholder
        shall sell all Shares for which an election is made.  If Killam
        does not elect to purchase any or all of such Shares, it shall
        give written notice thereof to ETK.  ETK shall then have the
        right to purchase any or all of such Shares.  If Killam and ETK
        do not elect to purchase such Shares, ETK shall give written
        notice thereof to the Management Group.  The members of the
        Management Group shall have the option to purchase such Shares in

                                        5PAGE
<PAGE>
        accordance with the provisions of Section 5.4(b) below.  The
        Closing for such purchases shall take place in accordance with
        Section 1.1.

                  (b)  If Killam or ETK do not elect to purchase all of a
        Shareholder's Shares in accordance with Section 5.4(a), they
        shall give written notice thereof to the Management Group.  Each
        member of the Management Group shall have the option to purchase
        any remaining Shares owned by such member in proportion with the
        total number of Shares then owned by all members of the
        Management Group who desire to purchase any Shares.  Each member
        shall have the right to purchase such Shares at the price and on
        the terms as shall be agreed upon between the member or members
        and the Selling Shareholder; provided, however, that if the
        purchase price is less than the purchase price at which Killam
        and ETK could otherwise purchase such Shares under Section
        5.4(a), Killam and ETK shall have an additional twenty (20) days
        from the date of any Bona Fide Offer, in writing, to elect to
        purchase such Shares at the reduced price.  If any member elects
        to exercise his option to purchase his portion of the Shares,
        such member shall give written notice of such election to the
        Selling Shareholder within ten (10) days after receipt of the
        notice from Killam or ETK, or within ten (10) days after the
        expiration of the additional twenty (20) day period provided for
        in the preceding sentence, whichever is later.  If any member of
        the Management Group does not elect to purchase any Shares in
        accordance with this Section, the Selling Shareholder shall give
        all members of the Management Group who have elected to purchase
        the Shares notice of the remaining number of Shares which may be
        proportionately purchased at the option of such members upon
        written notice to the Selling Shareholder within ten (10) days of
        such notice.

                  (c)  For purposes of this Agreement, the term
        "voluntary termination" shall include any voluntary actions on
        the part of an employee which results in a termination of
        employment, other than Retirement.  In the event any employee
        voluntarily terminates his employment during a period in which an
        employment agreement is in effect, such action shall be deemed to
        be a voluntary termination regardless of whether Killam
        subsequently characterizes such termination as an involuntary
        termination for breach of the employment agreement.

             5.5  Retirement. If any Shareholder ceases to be employed by
        Killam, or any Related Corporation, on account of Retirement,
        Killam or ETK, as determined by the companies, shall purchase and
        the Shareholder shall sell those Shares held by him at the time
        of his termination or any Shares thereafter acquired under the
        ISO Plan.  The Closing for such purchase shall take place in
        accordance with Section 1.1.

             6.1  Repurchase.  Notwithstanding any of the provisions
        contained in Article 4 or Article 5, Killam shall repurchase from
        the Shareholders and the Shareholders shall sell to Killam on
        January 1, 1997 and on January 1, 2000 (the "Repurchase Dates"),
        or as soon thereafter as reasonably possible, up to twenty-five
        percent (25%) of the Shares held by the Shareholders, or their
        estates or personal representatives, on each Repurchase Date,
        provided, however, that Killam may purchase no more than
        forty-three and three-quarters percent (43.75%) of the number of
        Shares held by any Shareholder, and the other members of the
        Management Group, immediately prior to the repurchase on January
        1, 1997.  Purchases required hereunder shall be made from any
        Shareholder, and the other members of the Management Group,
        either by lot, or on a pro rata basis, until all Shares required
        to be repurchased hereunder are so purchased.  The total number
        of Shares which Killam may repurchase hereunder shall be added to
        treasury stock and shall be available for issuance under the ISO
        Plan or any subsequent stock option plan to members of the
        Management Group or other key employees of Killam or Duncan in
        accordance with Article 3.

        Computation of Fair Market Value of Shares, as set forth in
        Exhibit A, unless a higher Purchase Price is required under
        Exhibit E hereof.

             7.2  Payment.  The Purchase Price for any Shares purchased
        by Killam pursuant to this Agreement shall be subject to offset

             Shareholder's employment, shall be paid upon such terms and

             8.1  Loans Due Killam.  Killam shall offset against any

        the amount of any loans or other indebtedness due from the
        Shareholder to Killam unless otherwise forgiven under the terms
        of the ISO Plan, and, to the extent so credited against the
        Purchase Price, such loan or other indebtedness shall be deemed
        to be and shall be canceled and discharged.  In the event that
        any Purchase Price is paid by ETK to a Shareholder, the
        Shareholder shall be required to use such proceeds to repay any
        indebtedness to Killam in accordance with the preceding sentence.

             8.2  Loans Due the Shareholder.  Any loan or other
        indebtedness due from Killam to a Shareholder shall be satisfied

             The following legend shall be conspicuously endorsed on each
        certificate representing any shares issued to Shareholder:

                  "The shares of stock represented by this certificate
                  are subject to restrictions on transfer, as contained
                  in the Shareholders Agreement dated __________, 19__,
                  as the same may be amended from time to time, a copy of
                  which is on file at the offices of Killam and will be
                  furnished upon request.  The shares of stock evidenced
                  by this certificate have not been registered under the
                  Securities Act of 1933 or under any applicable state
                  securities law, and may not be transferred except upon
                  delivery to the Corporation of an opinion of counsel
                  satisfactory in form and substance to it that such
                  transfer will not violate the Securities Act of 1933,
                  as amended, or any applicable state securities laws".

                                    SECURITY

             Upon the delivery of a promissory note pursuant to any of
        the provisions of this Agreement, a Shareholder shall deliver all
        of the Shares to be sold to an escrow agent mutually agreeable to
        the parties to this Agreement.  The escrow agent shall hold such
        Shares in accordance with the terms substantially similar to the
        Escrow Agreement attached hereto as Exhibit D. The Shareholder
        shall execute such additional documents as may be required by the
        escrow agent to transfer properly the Shares on the books of
        Killam.

             The Shares may be subject to a Pledge Agreement as further
        described in Section 12 of the ISO Plan.

                                        9PAGE
<PAGE>
             12.1  Creation of Surplus.  If Killam becomes obligated to
        purchase a Shareholder's Shares, and if Killam, pursuant to New
        Jersey law, does not have sufficient surplus to make payment as
        required under this Agreement or to effectuate or to enter into a
        valid redemption at such time, Killam shall promptly take all
        legal action to enable it to make payment out of surplus or to
        effectuate a valid redemption under New Jersey law, including,
        but not limited to the following:

                  (a)  A recapitalization of Killam so as to reduce its
             stated capital and increase its surplus in accordance with
             N.J.S.A. 14A:7-19; and

                  (b)  A reappraisal of the assets of Killam (including
             goodwill, if any) to reflect the market value of such assets
             on the books of Killam, in the event such value exceeds the
             book value thereof, so as to increase such surplus, if
             allowed by law.

             12.2  Inadequate Surplus.  If Killam does not have
        sufficient surplus under New Jersey law to effectuate or to enter
        into a lawful redemption of a Shareholder's unpurchased Shares,
        and if Killam is unable to take such action pursuant to this
        Article 12 so as to enable it to effectuate or to enter into a
        lawful redemption for all such Shares, then, notwithstanding any
        Provision in this Agreement to the contrary, Killam shall be
        obligated to purchase only those unpurchased Shares of the
        Shareholder as may be lawfully redeemed or purchased by it.


                                   ARTICLE 13
                                  MISCELLANEOUS

             13.1  Warranties.  At the time of purchase by Killam or ETK
        of any Shares held by a Shareholder, the Shareholder represents
        and warrants that he owns the Shares registered in his name on
        the books of Killam free and clear of any liens and encumbrances
        other than as set forth in this Agreement.

             13.2  Waiver, Modification, Cancellation.  Any waiver,
        alteration or modification of any of the provisions of this
        Agreement or cancellation or replacement of this Agreement shall
        not be valid unless in writing and signed by all of the parties
        hereto.

             13.3  Heirs and Successors.  This Agreement shall be binding
        upon Killam, ETK, the Shareholders, and their respective 

                                       10PAGE
<PAGE>
        successors, heirs, assigns and personal representatives, as the
        case may be.

             13.4  Entire Agreement.  This Agreement contains the entire
        agreement of the parties regarding the subject matter hereof and,
        together with the schedules attached hereto, supersedes all prior
        agreements, understandings and negotiations regarding the same.

             13.5  Further Assurances.  Each party hereto agrees to
        execute, acknowledge and deliver such further instruments, and to
        do all such other acts, as may be necessary or appropriate in
        order to carry out the purposes and intent of this Agreement.

             13.6  Waiver.  The waiver by either party of a breach of any
        provisions contained herein shall be in writing and shall in no
        way be construed as a waiver of any succeeding breach of such
        provision or the waiver of the provision itself.

             13.7  Choice of Law.  This Agreement shall be governed by
        and interpreted in accordance with the laws of the State of New
        Jersey as if the Agreement was performed wholly within such State
        and without regard to its conflict of law principles.

             13.8  Captions.  Paragraph captions are inserted for
        convenience only and in no way are to be construed to define,
        limit or affect the construction or interpretation hereof.

             13.9  Counterparts.  This Agreement may be executed in
        multiple counterparts, each of which shall be deemed an original,
        but all of which together shall constitute one and the same
        instrument.  If this Agreement is executed in counterparts, no
        signatory hereto shall be bound until each of the parties named
        below shall have duly executed or caused to be duly executed a
        counterpart of this Agreement.

             13.10  Notices.  Whenever under this provisions of this
        Agreement notice is required to be given, it shall be in writing
        and shall be deemed given when mailed, postage prepaid, by
        registered or certified mail, return receipt requested, addressed
        to the Shareholder, Killam or ETK at their respective addresses
        set forth in this Agreement, or to such other address as may
        appear on the record books of Killam.  Any party hereto may
        change its address for the provision of notice to it hereunder by
        notification to the other parties hereto in accordance with this
        Section 13.10.

                   AMENDMENT NO. 1 TO SHAREHOLDERS' AGREEMENT

             WHEREAS, Elson T. Killam Associates, Inc., a New Jersey
        corporation ("Killam"), Engineering, Technology and Knowledge
        Corporation, a Delaware corporation (formerly known as
        Environmental, Technology and Knowledge Corporation ("ETKC"), and
        certain persons (individually, a "Shareholder" and collectively,
        the "Shareholders") are parties to that certain Shareholders'
        Agreement dated as of the 29th day of January, 1995 (the
        "Shareholders' Agreement"); 

             WHEREAS, ETKC owns 100% of the outstanding capital stock of
        Killam (the "Killam Stock") and the Shareholders collectively own
        vested options (the "Killam Options") to purchase, in the
        aggregate, 1,590 additional shares of Killam Stock;

             WHEREAS, in the absence of any public trading market for
        Killam Stock, the Shareholders' Agreement contains certain
        provisions intended under certain identified circumstances to
        provide the Shareholders with liquidity with respect to their
        shares of Killam Stock;

             WHEREAS, pursuant to a Stock Purchase and Sale Agreement of
        even date herewith, Thermo Process Systems Inc., a Delaware
        corporation ("Thermo"), has acquired 100% of the outstanding
        capital stock of ETKC;

             WHEREAS, as of the date hereof, the Killam Options (after
        taking into account the cancellation of certain of the Killam
        Options) have been assumed by Thermo and have been converted into
        options to purchase shares of the common stock of Thermo, which
        shares are listed for trading on the American Stock Exchange and
        are freely tradable under U.S. securities laws in the public
        securities markets; and

             WHEREAS, the parties wish to clarify the Shareholders'
        Agreement to establish such public markets as the means to
        provide the Shareholders with the liquidity guaranteed by the
        Shareholders' Agreement;

             NOW, THEREFORE, in consideration of the foregoing, of the
        mutual promises set forth herein, and intending to be legally
        bound, the parties hereto hereby agree as follows:
         
             1.   The Shareholders' Agreement is amended by deleting
        Section 1.8 thereof in its entirety and substituting therefor the
        following:

                  "1.8 "SHARES" shall mean shares of the common stock of
             Thermo Process Systems Inc. acquired upon the exercise of

                                        1PAGE
<PAGE>
             options received by the Shareholders as of February 6, 1995
             (the "Thermo Options") upon the conversion of

             price or prices as may be obtainable and pay to the
             Shareholder an amount which is equal to the difference
             between the Floor Price and the amount which such
             Shareholder received (before taking into account
             commissions, taxes and other transaction costs) upon such
             sales.  The Shareholders agree, as a condition to such
             agreements by Thermo, to give Thermo reasonable prior
             written notice of any such intention to sell such Shares and

             of this Agreement, each Shareholder may pledge any or all of
             his Shares as collateral for any loans that may be needed to
             enable such Shareholder to pay any alternative minimum tax
             or other income tax due as a result of the exercise of the
             Thermo Options, provided, however, that any lender accepting
             such Shares as collateral shall continue to be prohibited
             from disposing of such Shares except in accordance with the
             provisions of Section 6.1 of this Agreement."
