   Item 2.  Acquisition or Disposition of Assets
            ------------------------------------

          On December 8, 1995, Thermo Process Systems Inc., through its Thermo
   Remediation Inc. subsidiary ("Thermo Remediation"), acquired all of the
   issued and outstanding capital stock of Remediation Technologies, Inc.
   ("RETEC") for a combination of cash and securities having an aggregate
   value of approximately $29.7 million.  The purchase price consisted of
   approximately $18.5 million in cash and units consisting of (i) 227,250
   shares of Thermo Remediation's common stock and (ii) warrants to purchase
   75,750 additional shares of Thermo Remediation's common stock at an
   exercise price of $14.85 per share, such units having an aggregate value of
   approximately $3.7 million.  In addition, Thermo Remediation assumed
   outstanding RETEC stock options and converted such options into options to
   purchase up to 897,000 shares of Thermo Remediation's common stock.  As
   converted, such options have a weighted average exercise price of $4.24 per
   share and were valued in the aggregate at approximately $7.5 million.

        RETEC, based in Concord, Massachusetts, is an integrated environmental
   services firm, with 15 offices nationwide, that focuses primarily on the
   remediation of former and active industrial sites contaminated with organic
   wastes and residues.  RETEC recorded revenues of approximately $39 million
   in the fiscal year ended December 31, 1994.

        The acquisition was made pursuant to an Agreement and Plan of Merger
   dated as of December 1, 1995 (the "Merger Agreement), among Thermo
   Remediation, TRI Acquisition Inc., a wholly owned subsidiary of Thermo
   Remediation ("Acquisition") and RETEC.  Under the terms of the Merger
   Agreement, which became effective on December 8, 1995, (i) Acquisition
   merged with and into RETEC, (ii) outstanding shares of RETEC's common stock
   were canceled and converted into the right to receive the purchase price,
   (iii) each outstanding share of Acquisition's common stock was canceled and
   converted into one share of the common stock of RETEC, and (iv) RETEC
   became a wholly owned subsidiary of Thermo Remediation.  

        The consideration paid for RETEC was based on Thermo Remediation's
   determination of the fair market value of RETEC's business, and the terms
   of the merger agreement were determined by arms' length negotiation among
   the parties.

        Thermo Remediation has no present intention to use RETEC's assets for
   purposes materially different from the purposes for which such assets were
   used prior to the acquisition.  However, Thermo Remediation will review
   RETEC's business and assets, corporate structure, capitalization,
   operations, properties, policies, management and personnel and, upon
   completion of this review, may develop alternative plans or proposals,
   including mergers, transfers of a material amount of assets or other
   transactions or changes relating to such business.

                          AGREEMENT AND PLAN OF MERGER


             Agreement entered into as of December 1, 1995 by and among
        Thermo Remediation, Inc., a Delaware corporation (the "Buyer"),
        TRI Acquisition Inc., a Delaware corporation and a wholly-owned
        subsidiary of the Buyer (the "Transitory Subsidiary"), and
        Remediation Technologies, Inc., a Delaware corporation (the
        "Company").  The Buyer, the Transitory Subsidiary and the Company
        are referred to collectively herein as the "Parties."

             This Agreement contemplates a taxable merger of the
        Transitory Subsidiary into the Company.  In such merger, the
        stockholders of the Company will receive cash and, if they file
        an election as set forth herein, capital stock of the Buyer in
        exchange for their capital stock of the Company.

             Now, therefore, in consideration of the representations,
        warranties and covenants herein contained, the Parties agree as
        follows.

                                    ARTICLE I

        conditions of this Agreement, the Transitory Subsidiary shall
        merge with and into the Company (with such merger referred to
        herein as the "Merger") at the Effective Time (as defined below).
        From and after the Effective Time, the separate corporate
        existence of the Transitory Subsidiary shall cease and the
        Company shall continue as the surviving corporation in the Merger
        (the "Surviving Corporation").  The "Effective Time" shall be the
        time at which the Company and the Transitory Subsidiary file the
        certificate of merger or other appropriate documents prepared and
        executed in accordance with the relevant provisions of the
        Delaware General Corporation Law (the "Certificate of Merger")
        with the Secretary of State of the State of Delaware, or such
        later time as shall be agreed to by the Buyer and the Company and
        be specific in said Certificate of Merger.  The Merger shall have
        the effects set forth in Section 259 of the Delaware General
        Corporation Law.

        contemplated by this Agreement (the "Closing") shall take place
        at the offices of Hale and Dorr in Boston, Massachusetts,
        commencing at 1:00 p.m. local time on December 8, 1995, or, if
        all of the conditions to the obligations of the Parties to
        consummate the transactions contemplated hereby have not been
        satisfied or waived by such date, on such mutually agreeable
        later date as soon as practicable after the satisfaction or

        Company shall deliver to the Buyer and the Transitory Subsidiary
        the various certificates, instruments and documents referred to
        in Section 5.2, (b) the Buyer and the Transitory Subsidiary shall
        deliver to the Company the various certificates, instruments and
        documents referred to in Section 5.3, (c) the Company and the

             1.4  Additional Action.  The Surviving Corporation may, at
        any time after the Effective Time, take any action, including

        of either the Company or the Transitory Subsidiary, in order to
        consummate the transactions contemplated by this Agreement.

             1.5  Conversion of Shares.  At the Effective Time, by virtue
        of the Merger and without any action on the part of any Party or
        the holder of any of the following securities:

        defined below) determined by dividing the Outstanding Company
        Share Value (as defined below) by the Unit Value (as defined
        below).   

                  (b)  Subject to Section 1.6 below, each Series A Share
        and each Series B Share other than the Unit Election Shares

        the Effective Time by a Company Stockholder who has not executed
        a written consent in favor of the adoption of this Agreement and
        the Merger (which such written consent in favor shall be deemed
        to have been given if a Form of Election is made in accordance
        with Section 1.7 below) and with respect to which appraisal shall
        have been duly demanded and perfected in accordance with
        Section 262 of the Delaware General Corporation Law and not
        effectively withdrawn or forfeited.  Dissenting Shares shall not
        be converted into or represent the right to receive the Merger
        Consideration, unless such Company Stockholder shall have
        forfeited his right to appraisal under the Delaware General
        Corporation Law or effectively withdrawn his demand for
        appraisal.  If such Company Stockholder has so forfeited or
        withdrawn his right to appraisal of Dissenting Shares, then
        (i) as of the occurrence of such event, such holder's Dissenting
        Shares shall cease to be Dissenting Shares and shall be converted
        into and represent the right to receive an amount of cash payable
        in respect of such Company Shares pursuant to Section 1.5(b), and
        (ii) promptly following the occurrence of such event, the Buyer
        shall deliver to the Escrow Agent under the Escrow Agreement
        (and, if the Escrow Agent has made a distribution to Company
        Stockholders in accordance with the terms of the Escrow
        Agreement, to the holders as appropriate) the cash payment to
        which such holder is entitled pursuant to Section 1.5(b).  Any
        amount delivered to the Escrow Agent under this Section 1.6(a)
        shall be considered part of the Escrow Fund for all purposes of
        this Agreement.

                  (b)  Within two (2) business days of the effectiveness
        of any written consent of Company Stockholders approving the
        Merger and this Agreement, the Company shall send written notice
        of such approval to those Company Stockholders as required by
        Section 228 of the Delaware General Corporation Law.

                  (c)  The Company shall give the Buyer (i) prompt notice
        of any written demands for appraisal of any Company Shares,
        withdrawals of such demands, and any other instruments that
        relate to such demands received by the Company and (ii) the
        opportunity to direct all negotiations and proceedings with
        respect to demands for appraisal under the Delaware General
        Corporation Law.  The Company shall not, except with the prior
        written consent of the Buyer or as ordered by the Court, make any
        payment with respect to any demands for appraisal of Company
        Shares or offer to settle or settle any such demands.

             1.7  Procedure for Unit Election. 

                  (a)  At the time of delivery of the Confidential
        Offering Memorandum/Information Statement provided for by Section
        4.3(a) below, the Company will deliver to each holder of record
        of Company Shares a Unit election form (the "Form of Election"),
        providing such holder with the option to elect to receive whole
        (but not fractional) Units with respect to all or any portion of
        such holder's Company Shares.  Any such election shall have been
        properly made only if duly completed and delivered to Robert W.
        Dunlap before the Effective Time.  Any Form of Election may be
        revoked by the person submitting the same only by written notice
        received by Robert W. Dunlap prior to the Effective Time.  In
        addition, all Forms of Election shall automatically be revoked if
        this Agreement is terminated for any reason.  If a Form of
        Election is revoked, the certificate or certificates representing
        Company Shares ("Certificates") to which such Form of Election
        relates shall be promptly returned to the person submitting the
        same.  The Company may determine whether or not any Form of
        Election has been properly made or revoked pursuant to this
        Section 1.7, and any such determination shall be conclusive and
        binding.  If the Buyer determines that any Form of Election was
        not properly or timely made, the Company Shares covered thereby
        shall not be treated as Unit Election Shares, and shall be
        converted in the Merger as provided in Section 1.5(b) hereof.

                  (b)  The filing of a form of Election shall be deemed
        for all purposes (including without limitation the ability to
        seek appraisal rights under Section 262 of the Delaware General
        Corporation Law) to constitute a written consent in favor of the
        Merger and this Agreement. 

             1.8  Procedure for Proration.  If the aggregate number of
        Company Shares for which Forms of Election have been filed and
        not revoked pursuant to Section 1.7 would not convert into a
        whole number of Units equal to the Merger Units, then each
        Company Stockholder filing a Form of Election shall be deemed to
        have filed (without any additional action on the part of the

        Unit Election Shares owned by all Company Stockholders filing a
        Form of Election, rounded up or down as appropriate (as
        determined by the Buyer) so that the number of Unit Election

        any request by the Escrow Agent.

                  (b)  In the event any Certificate shall have been lost,
        stolen or destroyed, upon the making of an affidavit of that fact
        by the person claiming such Certificate to be lost, stolen or
        destroyed, the Buyer shall issue in exchange for such lost,
        stolen or destroyed Certificate the Merger Consideration issuable
        in exchange therefor pursuant to Section 1.5.  The Board of
        Directors of the Buyer will require the owner of such lost,
        stolen or destroyed Certificate to give the Buyer indemnity
        against any claim that may be made against the Buyer with respect

        Stock on or after January 3, 1996 shall not be paid to former
        Company Stockholders entitled by reason of the Merger to receive
        Merger Units until such holders surrender their Certificates in
        accordance with Section 1.9 of the Agreement.  Upon such
        surrender, the Buyer shall pay or deliver to the persons in whose
        name the certificates representing such Merger Units are issued
        (including, without limitation, the Escrow Agent) any dividends
        or  other distributions that are payable to the holders of record

        the Escrow Agent by check or wire transfer funds in the amount of

        obligations set forth in Article VI of the Agreement.  The
        escrowed property shall be held by the Escrow Agent under the
        Escrow Agreement pursuant to the terms thereof.  The escrowed
        property shall be held as a trust fund and shall not be the
        subject of any lien, attachment, trustee process or any other
        judicial process of any creditor of any party, and shall be held
        and disbursed solely for the purposes and in accordance with the
        terms of the Escrow Agreement.

                  (b)  The adoption of this Agreement and the approval of
        the Merger by the Company Stockholders shall constitute their
        approval of and agreement to be bound by the terms of the Escrow

        Company Shares issued by the Company pursuant to its stock option
        plans or otherwise ("Options"), whether vested or unvested, shall
        be assumed by the Buyer.  Immediately after the Effective Time,
        each Option outstanding immediately prior to the Effective Time
        shall be deemed to constitute an option to acquire, on the same
        terms and conditions as were applicable under such Option at the
        Effective Time, such number of shares of Buyer Common Stock as is
        equal to the number of Company Shares subject to the unexercised
         portion of such Option multiplied by 2.2298 (the "Conversion
        Ratio"), with any fraction resulting from such multiplication to
        be rounded down to the nearest whole number.  The exercise price
        per share of each such assumed Option shall be equal to the
        exercise price of such Option immediately prior to the Effective
        Time, divided by the Conversion Ratio, with such quotient rounded
        up to the nearest whole cent.  The term, exercisability, vesting
        schedule, status as an "incentive stock option" under Section 422
         of the Internal Revenue Code of 1986 (as amended, the "Code"),
        if applicable, and all of the other terms of the Options shall
        otherwise remain unchanged.  As part of the Merger, certain
        holders of the Options shall be given an opportunity to have
        their Options converted into Buyer Common Stock upon a conversion
        ratio equal to 2.5461, in return for executing an Optionee
        Consent Agreement in the form attached hereto as Exhibit C (an
        "Optionee Consent Agreement")  whereby such holder agrees to
        participate in the Escrow Agreement and agrees to resale
        restrictions on shares of Buyer Common Stock acquired upon
        exercise of such Options. 

                  (b)  As soon as practicable after the Effective Time,
        the Buyer or the Surviving Corporation shall deliver to the
        holders of Options appropriate notices setting forth such
        holders' rights pursuant to such Options, as amended by this
        Section 1.12, and the agreements evidencing such Options shall
                                        7

        continue in effect on the same terms and conditions (subject to
        the amendments provided for in this Section 1.12 and such
        notice).

                  (c)  The Buyer shall take all corporate action
        necessary to reserve for issuance a sufficient number of shares
        of Buyer Common Stock for delivery upon exercise of the Options
        assumed in accordance with this Section 1.12.  As soon as
        practicable following the Effective Time, the Buyer shall file a
        Registration Statement on Form S-8 (or any successor form) under
        the Securities Act of 1933 (as amended, the "Securities Act")
        with respect to all shares of Buyer Common Stock subject to such
        Options that may be registered on a Form S-8, and shall use its
        best efforts to maintain the effectiveness of such Registration
        Statement for so long as such Options remain outstanding.

             1.13 Certificate of Incorporation.  The Certificate of
        Incorporation of the Surviving Corporation shall be amended as of
        the Effective Time so as to read in its entirety as the form
        annexed hereto as Exhibit D.

             1.14 By-laws.  The By-laws of the Surviving Corporation
        shall be the same as the By-laws of the Transitory Subsidiary
        immediately prior to the Effective Time, except that the name of
        the corporation set forth therein shall be changed to the name of
        the Company.

             1.15 Directors and Officers.  The directors of the
        Transitory Subsidiary shall become the directors of the Surviving
        Corporation as of the Effective Time.  The officers of the
        Company shall remain as officers of the Surviving Corporation
        after the Effective Time, retaining their respective positions.

             1.16 No Further Rights.  From and after the Effective Time,
        no Company Shares shall be deemed to be outstanding, and holders
         of Certificates shall cease to have any rights with respect
        thereto, except as provided herein or by law.

             1.17 Closing of Transfer Books.  At the Effective Time, the
        stock transfer books of the Company shall be closed and no
        transfer of Company Shares shall thereafter be made.  If, after
        the Effective Time, Certificates are presented to the Surviving
        Corporation or the Exchange Agent, they shall be cancelled and
        exchanged for Merger Consideration in accordance with
        Section 1.5, subject to Section 1.11 and to applicable law in the
        case of Dissenting Shares.

        modification or acceleration, under any such policy, or (ii) has
        received any notice from the insurer disclaiming coverage or
        reserving rights  with respect to a particular claim or any such
        policy in general.  Neither the Company nor any Subsidiary has
        incurred any loss, damage, expense or liability covered by any
        such insurance policy for which it has not properly asserted a
        claim under such policy.  Each of the Company and the
        Subsidiaries is covered by insurance in scope and amount
        sufficient to satisfy the insurance provision of each written
        arrangement listed or required to be listed in Section 2.14 of
        the Disclosure Schedule. 

               2.18    Litigation.  Section 2.18 of the Disclosure
        Schedule identifies, and contains a brief description of, (a) any
        unsatisfied judgment, order, decree, stipulation or injunction
        and (b) any claim, complaint, action, suit, proceeding, hearing
        or investigation of or in any Governmental Entity or before any
        arbitrator to which the Company or any Subsidiary is a party or,
        to the knowledge of the Company and the Subsidiaries, is
        threatened to be made a party. 

             2.19 Employees.  Section 2.19 of the Disclosure Schedule
        contains a list of all current employees of the Company and each
        Subsidiary, along with the position and the annual rate of
        compensation of each such person.  Each principal and associate

        confidentiality/assignment of inventions agreement with the
        Company or a Subsidiary, a copy of which has previously been
        delivered to the Buyer.  To the knowledge of the Company and its
        Subsidiaries, no key employee or group of employees has any plans
        to terminate employment with the Company or any Subsidiary.
        Neither the Company nor any Subsidiary is a party to or bound by
        any collective bargaining agreement, nor has any of them
        experienced any strikes, grievances, claims of unfair labor
        practices or other collective bargaining disputes.  The Company
        and the Subsidiaries have no knowledge of any organizational
        effort made or threatened, either currently or within the past
        two years, by or on behalf of any labor union with respect to
        employees of the Company or any Subsidiary.

        last five plan years for each Employee Benefit Plan, have been
        delivered to the Buyer.  Each Employee Benefit Plan has been
        administered in all material respects in accordance with its
        terms and each of the Company, the Subsidiaries and the ERISA
        Affiliates has in all material respects met its obligations with
        respect to such Employee Benefit Plan and has made all required
        contributions thereto.  The Company and all Employee Benefit
        Plans are in compliance in all material respects with the
        currently applicable provisions of ERISA and the Code and the
        regulations thereunder. 

                  (b)  There are no investigations by any Governmental
        Entity, termination proceedings or other claims (except claims
        for benefits payable in the normal operation of the Employee

        benefits under any Employee Benefit Plan that could give rise to
        any material liability.

                  (c)  All the Employee Benefit Plans that are intended
        to be qualified under Section 401(a) of the Code have received
        determination letters from the Internal Revenue Service to the
        effect that such Employee Benefit Plans are qualified and the
        plans and the trusts related thereto are exempt from federal
        income taxes under Sections 401(a) and 501(a), respectively, of
        the Code, no such determination letter has been revoked and
        revocation has not been threatened, and no such Employee Benefit
        Plan has been amended since the date of its most recent
        determination letter or application therefor in any respect, and
        no act or omission has occurred, that would adversely affect its
        qualification or materially increase its cost.

                  (d)  Neither the Company, any Subsidiary, nor any ERISA

        ERISA Affiliate been obligated to contribute to any

        ERISA).

                  (f)  There are no unfunded obligations under any
        Employee Benefit Plan providing benefits after termination of
        employment to any employee of the Company or any Subsidiary (or
        to any beneficiary of any such employee), including but not
        limited to retiree health coverage and deferred compensation, but
        excluding continuation of health coverage required to be
        continued under Section 4980B of the Code and insurance
        conversion privileges under state law.

                  (g)  No act or omission has occurred and no condition
        exists with respect to any Employee Benefit Plan maintained by
        the Company, any Subsidiary or any ERISA Affiliate that would
        subject the Company, any Subsidiary or any ERISA Affiliate to any
        material fine, penalty, tax or liability of any kind imposed
        under ERISA or the Code.

                  (h)  No Employee Benefit Plan is funded by, associated
        with, or related to a "voluntary employee's beneficiary
        association" within the meaning of Section 501(c)(9) of the Code.

                  (i)  No Employee Benefit Plan, plan documentation or
        agreement, summary plan description or other written
        communication distributed generally to employees by its terms
        prohibits the Company from amending or terminating any such
        Employee Benefit Plan.

                  (j)  Section 2.20(j) of the Disclosure Schedule
        discloses each:  (i) agreement with any director, executive
        officer or other key employee of the Company or any Subsidiary

        this Agreement, "Environmental Law" means any federal, state or

        Subsidiary, except for those that would not, individually or in
        the aggregate, have a material adverse effect on the assets,
        business, financial condition, results of operations or future
        prospects of the Company and the Subsidiaries.  There have been
        no releases of any Materials of Environmental Concern into the
        environment by the Company or any Subsidiary at any parcel of
        real property or any facility at which the Company or a
        Subsidiary formerly provided or is currently providing Services,
        or for which the Company or any Subsidiary may have any material
        liability under any Environmental Law.  With respect to any such
        releases of Materials of Environmental Concern, the Company or
        such Subsidiary has given all required notices to Governmental
        Entities (copies of which have been provided to the Buyer),
        except where the failure to give such notice would not,
        individually or in the aggregate, have a material adverse effect
        on the assets, business, financial condition, results of
        operations or future prospects of the Company and the
        Subsidiaries.  Neither the Company nor any Subsidiary is aware of
        any other releases of Materials of Environmental Concern for

        Company and the Subsidiaries, threatened civil or criminal
        litigation, written notice of violation or noncompliance, formal
        administrative or judicial proceeding, claim, cause of action,
        liability, investigation, citation, order, consent order, consent
        decree, inquiry or information request by any Governmental
        Entity, involving the Company or any Subsidiary, except those
        that will not, individually or in the aggregate, have a material
        adverse effect on the assets, business, financial condition,
        results of operations or future prospects of the Company and the
        Subsidiaries, relating to any of the following: (i) violation of
        any Environmental Law; (ii) violation of any permit, license or
        registration issued under any Environmental Law; (iii) the

        Concern, whether or not in compliance with Environmental Laws;
        (iv) the generation, storage, treatment, transportation,

        vibrations at or from any real property or facility formerly or
        currently owned or leased by the Company or a Subsidiary or at
        which the Company or a Subsidiary is providing Services; or
        (viii) the providing of negligent Services.  Without limiting the
        foregoing, none of the Company nor any Subsidiary has been named
        a "potentially responsible party" or has received any
        correspondence or notice that it may be named a "potentially
        responsible party."

                  (d)  The Company and the Subsidiaries possess all
        permits, licenses and/or registrations required under
        Environmental Laws for their business operations and the Services
        they provide, including permits, licenses and/or registrations
        required for equipment owned and/or operated by the Company and
        the Subsidiaries, and all such permits, licenses and/or

        Complete and accurate copies of each such report, or the results
        of each such investigation have been provided to the Buyer. 

                  (f)  To the knowledge of the Company and its
        Subsidiaries, all entities, including without limitation
        transporters, treatment, storage and disposal facilities, and
        remediation companies, used by the Company or a Subsidiary, or
        recommended by the Company or a Subsidiary while providing
        Services, for the transportation, storage, disposal, treatment or
        other handling of Materials of Environmental Concern possess all
        permits, licenses and registrations required under Environmental
        Laws, except those of which the failure to possess would not,
        individually or in the aggregate, have a material adverse effect
        on the assets, business, financial condition, results of
        operations or future prospects of the Company and the
        Subsidiaries.  To the knowledge of the Company, there is no
        previous, pending or threatened civil or criminal litigation,
        written notice of violation or noncompliance, formal
        administrative or judicial proceeding, investigation, citation,
        order, consent order, consent decree, inquiry or information
        request by any Governmental Entity, relating to such entities for
         any violations of Environmental Laws, except with respect to
        violations which, individually or in the aggregate, would not
        have a material adverse effect on the assets, business, financial
        condition, results of operations or future prospects of the
        Company and the Subsidiaries.

        businesses, are in compliance with each law (including rules and
        regulations thereunder) of any federal, state, local or foreign
        government, or any Governmental Entity, which is applicable to
        the Company or such Subsidiary or business, except for any
        violation of or default under a law which reasonably may be
        expected not to have a material adverse effect on the assets,
        business, financial condition, results of operations or future
        prospects of the Company or such Subsidiary.

        Permits that are required for the Company and the Subsidiaries to
        conduct their respective businesses as presently conducted or as
        proposed to be conducted, except for those the absence of which
        would not have any material adverse effect on the assets,
        business, financial condition, results of operations or future
        prospects of the Company and the Subsidiaries.  Each such Permit
        is in full force and effect and, to the best of the knowledge of
        the Company or any Subsidiary, no suspension or cancellation of
        such Permit is threatened and there is no basis for believing
        that such Permit will not be renewable upon expiration.  Each
        such Permit will continue in full force and effect following the
        Closing.

             2.24 Certain Business Relationships With Affiliates.  No

        contemplated by this Agreement.

             2.26 Books and Records.  The minute books and other similar
        records of the Company and each Subsidiary contain true and
        complete records of all actions taken at any meetings of the
        Company's or such Subsidiary's stockholders, Board of Directors
        or any committee thereof and of all written consents executed in
        lieu of the holding of any such meeting.  The books and records
        of the Company and each Subsidiary accurately reflect in all

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

             4.8  Exclusivity.  The Company shall not, and the Company
        shall use its best efforts to cause its Affiliates and each of
        its officers, directors, employees, representatives and agents
        not to, directly or indirectly, (a) encourage, solicit, initiate,
        engage or participate in discussions or negotiations with any
        person or entity (other than the Buyer) concerning any merger,
        consolidation, sale of material assets, tender offer,
        recapitalization, accumulation of Company Shares, proxy
        solicitation or other business combination involving the Company,
        any Subsidiary or any division of the Company or any Subsidiary
        or (b) provide any non-public information concerning the
        business, properties or assets of the Company or any Subsidiary
        to any person or entity (other than the Buyer). 

             4.9  Execution of Non-Competition Agreements.  The Company
        shall use its reasonable efforts to have those employees set
        forth in Schedule 4.09 execute a Non-Competition Agreement
        substantially in the form of Exhibit E hereto prior to the
        Closing.

             4.10 Listing of Merger Units.

                  The Buyer shall use its best efforts to list the Buyer
        Common Stock comprising the Merger Units and issuable upon
        exercise of the Buyer Warrants on the American Stock Exchange on
         or before the effectiveness of the Registration Statements (as
        defined below).

             4.11 Registration of Buyer Common Stock Comprising the
        Merger Units and Issuable Upon Exercise of the Buyer Warrants.

                  (a)  Within 30 days after the Effective Date, the Buyer
        shall file, and shall use its best efforts to have declared
        effective as promptly as practicable thereafter, a "shelf"
        registration statement (the "Unit Registration Statement") on
        Form S-3 pursuant to Rule 415 (or similar rule that may be
        adopted by the Securities and Exchange Commission (the "SEC")
        under the Securities Act for the resale by those Company
        Stockholders receiving Merger Units of the shares of Buyer Common
        Stock initially comprising the Merger Units (the "Initial
        Registrable Shares").  Except as set forth below, the Buyer
        agrees to use its best efforts to keep the Unit Registration
        Statement continuously effective and usable for resale of the
        Initial Registrable Shares for a period of 36 months after its
        effectiveness or if shorter when (i) all the Initial Registrable
        Shares have been sold pursuant to the Unit Registration Statement
        or (ii) the first date after the second anniversary of the
        Effective Time on which the largest number of Initial Registrable
        Shares then held by any former Company Stockholder constitutes
        less than 1% of the then outstanding shares of Buyer Common
        Stock.

                  (b)  Prior to the initial exercisability of the Buyer
        Warrants, the Buyer shall file, and shall use its best efforts to
        have declared effective as promptly as practicable thereafter, a
        "shelf" registration statement (the "Warrant Registration
        Statement") pursuant to Rule 415 (or similar rule that may be
        adopted by the SEC) under the Securities Act for the issuance of
        shares of Buyer Common Stock upon exercise of the Buyer Warrants
        (the "Warrant Registrable Shares").  Except as set forth below,
        the Buyer agrees to use its best efforts to keep the Warrant
        Registration Statement continuously effective and usable until
        the earlier of (i) the exercise of all Buyer Warrants that may be
        exercised or (ii) the expiration of the Buyer Warrants.

                  (c)  Buyer shall use its best efforts to qualify all
        initial Registrable Shares and Warrant Registrable Shares
        (collectively, the "Registrable Shares") under any applicable
        state securities laws; provided, however, that Buyer shall not be
        required to qualify as a foreign corporation or execute a general
        consent to service of process in any jurisdiction.

                  (d) From time to time, the Buyer will amend or
        supplement the Unit Registration Statement and the Warrant
        Registration Statement (collectively, the "Registration
        Statements") and any prospectus contained therein to the extent
        necessary to comply with the Securities Act and any applicable  
        state securities statute or regulations.  The Buyer will also
        provide the holder of Registrable Shares with as many copies of
        the prospectus contained in the appropriate Registration
        Statement and such other documents as such holder may reasonably
        request (including without limitation a copy of all documents
        filed with and correspondence from or to the SEC in connection
        with the appropriate Registration Statement). 

                  (e)  The Buyer shall be entitled to (i) postpone the
        filing or effectiveness of the Registration Statements or (ii) if
        effective, elect that the Registration Statements not be usable
        and require each Company Stockholder seeking to sell Initial
        Registrable Shares pursuant to the Unit Registration Statement or
        to acquire Warrant Registrable Shares pursuant to the Warrant
        Registration Statement to suspend sales or purchases pursuant to
        any prospectus contained therein, for a reasonable period of
        time, but not in excess of 60 days (a "Blackout Period"), if the
        Buyer determines in good faith that the registration and
        distribution of Registrable Shares (or the use of the
        Registration Statements or any related prospectus) would
        interfere with any pending material acquisition, material
        corporate reorganization or any other material corporate
        development involving the Buyer or any of its subsidiaries or
        would require premature disclosure thereof.  The Buyer shall
        promptly give each Company Stockholder seeking to sell or
        purchase Registrable Shares pursuant to the Registration
        Statements written notice of such determination, containing a
        general statement of the reasons for such postponement or
        restriction on use and an approximation of the anticipated delay;
                                       36

<PAGE>





        provided, however, that the aggregate number of days included in
        all Blackout Periods during any consecutive 12 months shall not
        exceed 120 days.

                  (f)  If (i) the Buyer shall file a registration
        statement (other than in connection with the registration of
        securities issuable pursuant to an employee stock option, stock
        purchase or similar plan or pursuant to a merger, exchange offer
        or a transaction of the type specified in Rule 145(a) under the
        Securities Act) with respect to Buyer Common Stock and (ii) with
        reasonable prior notice, the Buyer (in the case of a
        non-underwritten offering by the Buyer pursuant to such Initial
        registration statement) advises Company Stockholder seeking to
        sell Initial Registrable Shares pursuant to the Unit Registration
        Statement or to sell Warrant Registrable Shares following the
        exercise of Buyer Warrants in writing that a public sale or
        distribution of such Registrable Shares would adversely affect
        such offering or the managing underwriter (in the case of an
        underwritten offering by the Buyer pursuant to such registration
        statement) advises Company Stockholders seeking to sell such
        Registrable Shares in writing that such public sale or
        distribution would adversely affect such offering, then each
        Company Stockholder seeking to sell Initial Registrable Shares  
        pursuant to the Unit Registration Statement or to sell Warrant
        Registrable Shares following the exercise of Buyer Warrants
        shall, to the extent not prohibited by applicable law,
        (x) refrain from effecting any public sale or distribution of
        such Registrable Shares commencing on the effectiveness of such
        registration statement, (y) be entitled to include such
        Registrable Shares in such registration statement, subject to
        customary underwriter cut back, and sell such Registrable Shares
        pursuant thereto, and (z) sign a customary lock-up agreement with
        the managing underwriter (in the case of an underwritten
        offering) or the Buyer of scope and duration identical to the
        scope and duration of the lock-up agreement signed by the Buyer
        and each director and executive officer of the Buyer, but in no
        event to exceed 90 days.

                  (g)  Each Company Stockholder seeking to sell Initial
        Registrable Shares pursuant to the Unit Registration Statement
        shall provide in writing all information reasonably requested by
        the Buyer for inclusion in or in connection with the Unit
        Registration Statement and any such information shall not contain
        any untrue statement of a material fact or omit to state a
        material fact required to be stated therein or necessary in order
        to make the statements therein, in light of the circumstances
        under which they were made, not misleading.

                  (h)  The Buyer will indemnify and hold harmless each
        holder of Registrable Shares (including any broker or dealer
        through whom such shares may be sold) and each person, if any,
        who controls such holder or any such broker or dealer within the
        meaning of Section 15 of the Securities Act from and against any
        and all losses, claims, damages, expenses or liabilities, joint
                                       37

        or several, to which they or any of them become subject under the
        Securities Act, applicable state securities laws or under any
        other statute or at common law or otherwise, as incurred, and,
        except as hereinafter provided, will reimburse each such holder
        and each such controlling person, if any, for any legal or other
        expenses reasonably incurred by them or any of them in connection
        with investigating or defending any actions whether or not
        resulting in any liability insofar as such losses, claims,
        damages, expenses, liabilities or actions arise out of or are
        based upon any untrue statement or alleged untrue statement of a
        material fact contained in the Registration Statements, in any
        preliminary or amended preliminary prospectus or in the final
        prospectus (or the Registration Statements or any such prospectus
        as from time to time amended or supplemented by the Buyer), or
        arise out of or are based upon the omission or alleged omission
        to state therein a material fact required to be stated therein or
        necessary in order to make the statements therein, in the light
        of the circumstances in which they were made, not misleading, or
        any violation by the Buyer of any rule or regulations promulgated
        under the Securities Act or any state securities laws applicable
        to the Buyer and relating to action or inaction required of the  
        Buyer in connection with such registration.  Notwithstanding the
        foregoing, the Buyer shall have no obligation to indemnify any
        such holder or controlling person if:  (i) such untrue statement
        or omission was made in such Registration Statement, preliminary
        or amended preliminary prospectus or final prospectus in reliance
        upon and in conformity with information furnished in writing to
        the Buyer in connection therewith by such holder of Registrable
        Shares (in the case of indemnification of such holder) or such
        controlling person (in the case of indemnification of such
        controlling person) expressly for use therein, or (ii) such
        untrue statement or alleged untrue statement or omission or
        alleged omission was contained in a preliminary prospectus and
        corrected in a final or amended prospectus copies of which were
        delivered to such holder of Registrable Shares on a timely basis,
        and such holder of Registrable Shares failed to deliver a copy of
        the final or amended prospectus at or prior to the confirmation
        of the sale of the Registrable Shares to the person asserting any
        such loss, claim, damage or liability in any case where such
        delivery is required by the Securities Act.

                  (i)  Each holder of the Registrable Shares so
        registered will indemnify and hold harmless the  Buyer, each of
        its directors, each of its officers who have signed or otherwise
        participated in the preparation of the Registration Statements
        and each person, if any, who controls the Buyer within the
        meaning of Section 15 of the Securities Act from and against any
        and all losses, claims, damages, expenses or liabilities, joint
        or several, to which they or any of them may become subject under
        the Securities Act, applicable state securities law or under any
        other statute or at common law or otherwise, and, except as
        hereinafter provided, will reimburse the Buyer and each such
        director, officer, or controlling person for any legal or other
        expenses reasonably incurred by them or any of them in connection
                                       38

        with investigating or defending any actions whether or not
        resulting in any liability, insofar as such losses, claims,
        damages, expenses, liabilities or actions arise out of or are
        based upon any untrue statement of a material fact contained in
        the Registration Statements, in any preliminary or amended
        preliminary prospectus or in the final prospectus (or in the
        Registration Statements or any such prospectus as from time to
        time amended or supplemented) or arise out of or are based upon
        the omission to state therein a material fact required to be
        stated therein or necessary in order to make the statements
        therein not misleading, but only to the extent that such
        statement or omission was made in reliance upon and in conformity
        with information furnished in writing to the Buyer in connection
        therewith by such holder of Registrable Shares expressly for use
        therein.  The Company Stockholders' obligations hereunder shall
        be limited to an amount equal to the proceeds received by such
        holder of Registrable Shares sold in or following any such
        registration. 

                  (j)  If any action or proceeding (including any
        governmental investigation) shall be brought or asserted against
        any person entitled to indemnification under the provisions in
        this Section 4.11 (an "Indemnitee") in respect of which indemnity
        may be sought form any party who has agreed to provide such
        indemnification in this Section 4.11 (an "Indemnitor"), the
        Indemnitor shall assume the defense thereof, including the
        employment of counsel selected by the Indemnitor and shall assume
        the payment of all expenses.  Such Indemnitee shall have the
        right to employ separate counsel in any such action and to
        participate in the defense thereof, but the fees and expenses of
        such counsel shall be at the expense of such Indemnitee.  The
        Indemnitor shall not be liable for any settlement of any such
        action or proceedings effected without its written consent, but
        if settled with its written consent, or if there be a final
        judgment for the plaintiff in any such action or proceeding, the
        Indemnitor shall indemnify and hold harmless such Indemnitee from
        and against any loss or liability (to the extent stated above) by
        reason of such settlement or judgment.

                  (k)  In order to provide for just and equitable
        contribution to joint liability under the Securities Act in any
        case in which the Buyer or any holder of Registrable Shares makes
        a claim for indemnification pursuant to this Section 4.11 but it
        is judicially determined (by the entry of a final judgment or
        decree by a court of competent jurisdiction and the expiration of
        time to appeal or the denial of the last right of appeal) that
        such indemnification may not be enforced in such case
        notwithstanding that this Section 4.11 provides for
        indemnification, in such case, then the Buyer and such holder of
        Registrable Shares will contribute to the aggregate losses,
        claims, damages or liabilities to which they may be subject
        (after contribution from others) in such proportion as is
        appropriate to reflect the relative fault of the Buyer on the one
        hand and of the holder of Registrable Shares on the other in
                                       39

<PAGE>





        connection with the statements or omission which resulted in such
        losses, claims, damages or liabilities, as well as any other
        relevant equitable considerations or, if the allocation provided
        herein is not permitted by applicable law, in such proportion as
        shall be appropriate to reflect the relative benefits received by
        the Buyer and any holder of Registrable Shares form the offering
        of the securities covered by such Registration Statements.  The
        relative fault of the Buyer on the one hand and of the holder of
        Registrable Shares on the other shall be determined by reference
        to, among other things, whether the untrue or alleged untrue
        statement of a material fact or omission or alleged omission to
        state a material fact relates to information supplied by the
        Buyer on the one hand or by the holder of Registrable Shares on
        the other, and each party's relative intent, knowledge, access to
        information and opportunity to correct or prevent such statement
        or omission; provided, however, that, in any such case (i) no
        such  holder of Registrable Shares will be required to contribute
        any amount in excess of the proceeds received by such holder of
        Registrable Shares offered by it pursuant to the Unit
        Registration Statement or sold following the acquisition thereof
        pursuant to the Warrant Registration Statement; and (ii) no
        person or entity guilty of fraudulent misrepresentation within
        the meaning of Section 11(f) of the Securities Act will be
        entitled to contribution from any person or entity who was no
        guilty of such fraudulent misrepresentation. 

                  (l)  The Buyer shall timely file with the SEC such
        information as the SEC may require under Section 13 or 15(d) of
        the Exchange Act; and in such event, the Buyer shall use its best
        efforts to take all action pursuant to Rule 144(c) as may be
        required as a condition to the availability of Rule 144 under the
        Securities Act (or any successor exemptive rule hereinafter in
        effect) with respect to Buyer Common Stock.  The Buyer shall
        furnish to any holder of Registrable Shares forthwith upon
        request (i) a written statement by the Buyer as to its compliance
        with the reporting requirements of Rule 144(c), (ii) a copy of
        the most recent annual or quarterly report of the Buyer as filed
        with the SEC, and (iii) such other publicly-filed reports and
        documents as a holder may reasonable request in availing itself
        of any rule or regulation of the SEC allowing a holder to sell
        any such Registrable Shares without registration. 

                  (m)  The Buyer shall bear all costs and expenses of
        such registration, including, but not limited to, printing, legal
        and accounting expenses, SEC and NASD filing fees and all related
        "Blue Sky" fees and expenses, provided, however, that the Buyer
        shall have no obligation to pay or otherwise bear any portion of
        the underwriters' commissions or discounts attributable to the
        Registrable Shares being offered and sold by the Company
        Stockholders, or the fees and expenses of any counsel  or other
        advisor for the Company Stockholders in connection with such
        registration.

             4.12 Continuation of Insurance.  Until the second
        anniversary of the Effective Date and provided that such
        insurance is available, the Buyer will maintain insurance
        policies in place insuring the Surviving Corporation and
        liabilities of the Company in scope and at levels no less than
        that currently in effect for the Company, including "tail"
        coverage for such policies, where applicable, to the year
        currently covered by the Company's policies.  If during such two
        year period a claim for indemnification is made hereunder or
        under the Escrow Agreement, and such claim may be covered by any
        of such insurance policies such policies will be continued in
        force to provide recovery if necessary to do so. 

             4.13 No Short Selling.  The Company and the Buyer shall use
        their reasonable best efforts to ensure that no Company
        Stockholder receiving Units and no holder of an Option engage in
        short sales of Buyer Common Stock following the Effective Time.

                                 INDEMNIFICATION

             6.1  Of the Buyer and the Company.  If the Closing occurs,
        the Buyer, the Company and each Subsidiary shall be indemnified
        and held harmless from and against any and all claims, damages,

        (including, without limitation, settlement costs and any legal,

        whether or not involving a third-party claim (collectively, the
        "Damages") arising out of, constituting or related to each and
        all of the following:

                  (a)  any misrepresentation or breach of any

        this Agreement or in any statement, certificate or Schedule
        furnished by the Company pursuant to this Agreement;

        Section 4.13 hereof) or any other agreement, instrument or
        document contemplated by this Agreement;

                  (c)  resulting from (i) any release of any Materials of
        Environmental Concern into the environment relating to the
        operation of the business of the Company or any Subsidiary or any
        predecessor business or company of the Company or any Subsidiary
        prior to the Closing Date (including without limitation with
        respect to the transportation of Materials of Environmental
        Concern or the off-site storage, treatment, reclamation,
        recycling or disposal thereof); (ii) any release of any Materials
        of Environmental Concern at any location prior to the Closing
        Date if such release could give rise under any Environmental Law
        to liability on the part of the Company or any Subsidiary or any
        predecessor business or company of the Company or any Subsidiary;
        or (iii) any violation of any Environmental Law by the Company or

                  (d)  any liability for Taxes relating to operation of
        the Company or any Subsidiary for any period prior to the Closing
        (except to the extent of reserves specifically therefor on the
        Most Recent Balance Sheet);

                  (e)  resulting from any failure of any Company
        Stockholders to have good, valid and marketable title to the
        issued and outstanding Company Shares held by such Company
        Stockholders, free and clear of all liens, claims, pledges,
        options, adverse claims or charges of any nature whatsoever; or

                  (f)  resulting from any claim by a stockholder or
        former stockholder of the Company, or any other person, firm,
        corporation or entity, seeking to assert, or based upon: (i)
        ownership or rights to ownership of any shares of capital stock
        of or equity interest in the Company; (ii) any rights under the
        Certificate of Incorporation or By-laws of the Company; or (iii)
        any claim that his, her or its shares were wrongfully repurchased
        by the Company at any time prior to the Closing.

                  The obligations of the Company Stockholders to
        indemnify and hold harmless the Buyer, the Company and each
        Subsidiary shall in each case be joint and several obligations,
        except that the liability of each Company Stockholder with
        respect to Damages specified in Section 6.1(e) shall be several,
        and not joint. 

             6.2  Of the Company Stockholders.  If the Closing occurs,
        the Buyer hereby agrees to indemnify and hold harmless each

                  (a)  any misrepresentation or breach of any
        representation or warranty made by the Buyer in this Agreement;

                  (b)  any breach of any covenant, agreement or
        obligation of the Buyer contained in this Agreement or any other

        certificate or schedule furnished by the Buyer pursuant to this
        Agreement or in connection with the transactions contemplated by
        this Agreement; or

                  (d)  except as otherwise provided herein (including
        without limitation in Section 6.1), the Company's operation after
        the Closing (provided that no such indemnification shall be
        provided with respect to any facts which would require
        indemnification of the Buyer or the Company in Section 6.1 if a
        claim was made therefor within the periods set forth in Section
        6.5).

             6.3  Claims for Indemnification. 

                  (a)  Whenever any claim shall arise for indemnification
        under this Section 6, the party seeking indemnification (the
        "Indemnified Party"), shall promptly notify the party from whom  
        indemnification is sought (the "Indemnifying Party") of the claim
        and, when known, the facts constituting the basis for such claim
        with as much specificity and particularity as practicable under
        the circumstances; provided, however, that no delay on the part
        of the Indemnified Party in notifying any Indemnifying Party
        shall relieve the Indemnifying Party from any liability or
        obligation hereunder except to the extent of any damage or
        liability caused by or arising out of such failure. 

                  (b)  All claims for indemnification not involving any
        claim or legal proceeding by a third party shall be made in
        accordance with the procedures set forth in the Escrow Agreement.

                  (c)  In the event of any such claim for indemnification
        hereunder resulting from or in connection with any claim or legal
        proceeding by a third party, the notice shall specify, if known,
        the amount or an estimate of the amount of the liability arising
        therefrom and shall include copies of all suit, service and claim
        documents.  The Indemnified Party shall not settle or compromise
        any claim by a third party for which it is entitled to
        indemnification hereunder without the prior written consent,
        which shall not be unreasonably withheld or delayed, of the
        Indemnifying Party; provided, however, that if suit shall have
        been instituted against an Indemnified Party and the Indemnifying
        Party shall not have taken control of such suit after
        notification thereof as provided in Section 6.4 of this
        Agreement, the Indemnified Party shall have the right to settle
        or compromise such claim as provided in Section 6.4.  The
        Indemnification Representative shall have the power and authority
        to bind all the Company Stockholders for all purposes of this
        Section 6.

                  (d)  The parties agree that, prior to submitting any
        claim for indemnification under this Article VI, they shall use
        reasonable efforts to determine the amount, if any, by which
        their losses would be offset by an Indemnified Party's recovery
        of insurance proceeds and reduction of tax liabilities and to
        provide the Indemnifying Party notice of and a description of
        such determination.  All claims for indemnification shall provide
        for appropriate adjustments as a result of such reductions.

             6.4  Defense by the Indemnifying Party.  In connection with
        any claim which may give rise to indemnity hereunder resulting
        from or arising out of any claim or legal proceeding by a person
        other than the Indemnified Party, the Indemnifying Party may,
        upon written notice to the Indemnified Party, assume the defense
        of any such claim or legal proceeding if the Indemnifying Party
        acknowledges to the Indemnified Party in writing the obligation
        of the Indemnifying Party to indemnify the Indemnified Party with
                                       46
PAGE
<PAGE>





        respect to all elements of such claim.  If the Indemnifying Party
        assumes the defense of any such claim or legal proceeding, the
        Indemnifying Party shall select counsel reasonably acceptable to
         the Indemnified Party to conduct the defense of such claims or
        legal proceedings and shall take all steps necessary in the
        defense or settlement thereof.  The Indemnifying Party shall bear
        its costs and expenses incurred in connection with its defense of
        any claim under this Section 6.4, provided that, if the Buyer of
        the Company is the Indemnified Party, the Indemnifying Party, if
        it assumes the control of such claim, may be reimbursed for its
        reasonable out-of-pocket costs in connection with such defense
        from the amounts then held pursuant to the Escrow Agreement
        pursuant to the procedures set forth therein.  The Indemnifying
        Party shall not consent to a settlement of, or the entry of any
        judgment arising from, any such claim or legal proceeding,
        without the prior written consent of the Indemnified Party (which
        consent shall not be unreasonably withheld or delayed) unless the
        terms thereof provide for the unconditional release and discharge
        of the Indemnified Party; provided that if the Indemnified Party
        is the Buyer or the Company, the Indemnifying Party shall not
        consent to a settlement of, or the entry of any judgment arising
        from, any such claim or legal proceeding without the consent of
        the Buyer where the Buyer or the Company shall have reasonably
        demonstrated that the circumstances surrounding such settlement
        or judgment could result in an adverse impact upon the business,
        operations, assets or financial position of the Buyer, the
        Company or any Subsidiary.  The Indemnified Party shall be
        entitled to participate in (but not control) the defense of any
        such action, with its own counsel and at its own expense (except
        that the Indemnifying Party will be responsible for the fees and
        expenses of the separate co-counsel to the extent the Indemnified
        Party reasonably concludes that the counsel the Indemnifying
        Party has selected has a conflict of interest).  If the
        Indemnifying Party does not assume the defense of any such claim
        or litigation resulting therefrom as provided in this Section 6.4
        within thirty (30) days after the date that the Indemnified Party
        has given notice of the claim to the Indemnifying Party:  (a) the
        Indemnified Party may defend against such claim or litigation in
        such manner as he or it may deem appropriate, including, but not
        limited to, settling such claim or litigation on such terms as
        the Indemnified Party may deem appropriate; and (b) the
        Indemnifying Party shall be entitled to participate in (but not
        control) the defense of such action, with his or its counsel and
        at his or its own expense.

             6.5  Survival.  The representations and warranties of the
        Company set forth in this Agreement shall survive the Closing and
        the consummation of the transactions contemplated hereby and
        continue until 24 months after the Closing Date and shall not be
        affected by any examination made for or on behalf of the Buyer or
        the knowledge of any of the Buyer's officers, directors,
        stockholders, employees or agents.  Notwithstanding the
        foregoing, the representations and warranties contained in
        Section 2.2 relating to capitalization and the representations
                                       47
PAGE
<PAGE>





        and warranties  contained in Section 2.9 relating to tax matters
        shall survive the Closing and the consummation of the
        transactions contemplated thereby and continue until 90 days
        after the expiration of the applicable statute of limitations
        relating to such representations and the representations and
        warranties contained in Section 2.3 relating to authorization of
        the Merger shall survive without limitation.  If a notice is
        given in accordance with the Escrow Agreement before expiration
        of such periods, then (notwithstanding the expiration of such
        time period) the representation or warranty applicable to such
        claim shall survive until, but only for purposes of, the
        resolution of such claim.  No claim for indemnification may be
        made except within the time periods specified herein.

             6.6  Limitations.  Notwithstanding anything to the contrary
        herein, (a) the aggregate liability of the Company Stockholders
        for Damages under this Article VI shall not exceed the Escrow
        Property (as defined in the Escrow Agreement), except with
        respect to claims made in connection with the breaches of
        representations and warranties in Section 2.2 and 2.3, or
        pursuant to Section 6.1(d), (e) or (f), as to which such
        liability shall not be limited to the Escrow Property, but shall
        not exceed the Cash Consideration and Merger Units (or proceeds
        from the sale thereof) received by the Company Stockholders
        hereunder, and (b) except for claims pursuant to Section 9.11,
        the Buyer shall not receive indemnification under this Article VI
        unless and until the aggregate Damages exceed $300,000 (at which
        point the Buyer shall be indemnified for the aggregate Damages
        (subject to the limitation in the foregoing clause (a)), and not
        just the amounts in excess of $300,000).  Except with respect to
        claims based on fraud, the rights of the Indemnified Persons
        under this Article VI shall be the exclusive remedy of the
        Indemnified Persons with respect to claims resulting from or
        relating to any misrepresentation, breach of warranty or failure
        to perform any covenant or agreement of the Company contained in
        this Agreement.  No Company Stockholder shall have any right of
        contribution against the Company with respect to any breach by
        the Company of any of its representations, warranties, covenants
        or agreements.  In any circumstances in which the Company
        Stockholders may be liable for amounts in excess of the Escrow
        Property, recovery shall be had first against the Escrow
        Property, as appropriate, and second (to the extent the Escrow
        Property is insufficient to satisfy such claims) from the
        remaining Cash Consideration and  Merger Units (or proceeds from
        the sale thereof).

                                  MISCELLANEOUS

             9.1  Press Releases and Announcements.  No Party shall issue
        any press release or public disclosure relating to the subject
        matter of this Agreement without the prior approval of the other
        Parties; provided, however, that any Party may make any public
        disclosure it believes in good faith is required by law or
        regulation (in which case the disclosing Party shall advise the
        other Parties and provide them with a copy of the proposed
        disclosure prior to making the disclosure).

             9.2  No Third Party Beneficiaries.  This Agreement shall not
        confer any rights or remedies upon any person other than the
        Parties and their respective successors and permitted assigns;
        provided, however, that the provisions in Article I concerning
        issuance of the Merger Units and in Section 4.11 concerning
        registration rights are intended for the benefit of the Company
        Stockholders.

             9.3  Entire Agreement.  This Agreement (including the
        documents referred to herein) constitutes the entire agreement
        among the Parties and supersedes any prior understandings,
        agreements, or representations by or among the Parties, written
        or oral, with respect to the subject matter hereof.

             9.4  Succession and Assignment.  This Agreement shall be
        binding upon and inure to the benefit of the Parties named herein
        and their respective successors and permitted assigns.  No Party
        may assign either this Agreement or any of its rights, interests,
        or obligations hereunder without the prior written approval of
        the other Parties; provided that the Transitory Subsidiary may
        assign its rights, interests and obligations hereunder to an
        Affiliate of the Buyer.

             9.5  Counterparts.  This Agreement may be executed in two or

        instrument.

             9.6  Headings.  The section headings contained in this

        Any Party may give any notice, request, demand, claim, or other
        communication hereunder using any other means (including personal
        delivery, expedited courier, messenger service, telecopy, telex,
        ordinary mail, or electronic mail), but no such notice, request,
        demand, claim, or other communication shall be deemed to have
                                       52

        been duly given unless and until it actually is received by the
        party for whom it is intended.  Any Party may change the address
        to which notices, requests, demands, claims, and other
        communications hereunder are to be delivered by giving the other
        Parties notice in the manner herein set forth.

             9.8  Governing Law.  This Agreement shall be governed by and
        construed in accordance with the internal laws (and not the law
        of conflicts) of the Commonwealth of Massachusetts.

             9.9  Amendments and Waivers.  The Parties may mutually amend
        any provision of this Agreement at any time prior to the
        Effective Time; provided, however, that any amendment effected
        subsequent to the Requisite Stockholder Approval shall be subject
        to the restrictions contained in the Delaware General Corporation
        Law.  No amendment of any provision of this Agreement shall be
        valid unless the same shall be in writing and signed by all of
        the Parties.  No waiver by any Party of any default,
        misrepresentation, or breach of warranty or covenant hereunder,
        whether intentional or not, shall be deemed to extend to any
        prior or subsequent default, misrepresentation, or breach of
        warranty or covenant hereunder or affect in any way any rights
        arising by virtue of any prior or subsequent such occurrence.

             9.10 Severability.  Any term or provision of this Agreement
        that is invalid or unenforceable in any situation in any
        jurisdiction shall not affect the validity or enforceability of
        the remaining terms and provisions hereof or the validity or
        enforceability of the offending term or provision in any other
        situation or in any other jurisdiction.  If the final judgment of
        a court of competent jurisdiction declares that any term or
        provision hereof is invalid or unenforceable, the Parties agree
        that the court making the determination of invalidity or
        unenforceability shall have the power to reduce the scope,
        duration, or area of the term or provision, to delete specific  
        words or phrases, or to replace any invalid or unenforceable term
        or provision with a term or provision that is valid and
        enforceable and that comes closest to expressing the intention of
        the invalid or unenforceable term or provision, and this
        Agreement shall be enforceable as so modified after the
        expiration of the time within which the judgment may be appealed.

             9.11 Expenses.  Except as set forth in the Escrow Agreement,
        each of the Parties shall bear its own costs and expenses
        (including legal fees and expenses) incurred in connection with
        this Agreement and the transactions contemplated hereby;
        provided, however, that if the Merger is consummated, the Company
        and the Subsidiaries shall not incur more than an aggregate of
        $100,000 in out-of-pocket fees and expenses (including legal and
        accounting, but excluding internal marketing and analysis fees
        and expenses) in connection with the Merger, and any fees and
        expenses incurred by the Company or its Subsidiaries in excess of
        such amount shall be recovered by the Buyer pursuant to the

                                       53

        Escrow Agreement without regard to the provisions of the first
        sentence of Section 6.6.

             9.12 Specific Performance.  Each of the Parties acknowledges
        and agrees that one or more of the other Parties would be damaged
        irreparably in the event any of the provisions of this Agreement
        are not performed in accordance with their specific terms or
        otherwise are breached.  Accordingly, each of the Parties agrees
        that the other Parties shall be entitled to an injunction or
        injunctions to prevent breaches of the provisions of this
        Agreement and to enforce specifically this Agreement and the
        terms and provisions hereof in any action instituted in any court
        of the United States or any state thereof having jurisdiction
        over the Parties and the matter (subject to the provisions of
        Section 9.13), in addition to any other remedy to which it may be
        entitled, at law or in equity.

             9.13 Submission to Jurisdiction.  Each of the Parties
        (a) submits to the jurisdiction of any state or federal court
        sitting in Massachusetts in any action or proceeding arising out
        of or relating to this Agreement, (b) agrees that all claims in
        respect of the action or proceeding may be heard and determined
        in any such court, and (c) agrees not to bring any action or
        proceeding arising out of or relating to this Agreement in any
        other court.  Each of the Parties waives any defense of
        inconvenient forum to the maintenance of any action or proceeding
        so brought and waives any bond, surety or other security that
        might be required of any other Party with respect thereto.  Any
        Party may make service on another Party by sending or delivering
        a copy of the process to the Party to be served at the address
        and in the manner provided for the giving of notices in
        Section 9.7.  Nothing in this Section 9.13, however, shall affect
        the right of any Party to serve legal process in any other manner
        permitted by law.

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

             9.15 Incorporation of Exhibits and Schedules.  The Exhibits
        and Schedules identified in this Agreement are incorporated
        herein by reference and made a part hereof.

                                                             EXHIBIT 2(b)


                                ESCROW AGREEMENT


             This Escrow Agreement (the "Agreement") is entered into as
        of December 8, 1995, by and among Thermo Remediation Inc., a
        Delaware corporation (the "Buyer"), Robert W. Dunlap and Thomas
        M. Zimmer (the "Indemnification Representatives"), those persons
        or entities set forth in Schedule I hereto and State Street Bank
        and Trust Company, a Massachusetts trust company (the "Escrow
        Agent").

             WHEREAS, the Buyer and Remediation Technologies, Inc. (the
        "Company") have entered into an Agreement and Plan of Merger
        dated December 1, 1995 (the "Merger Agreement") by and among the
        Company, the Buyer and a subsidiary of the Buyer, pursuant to
        which such subsidiary will be merged into the Company which, as
        the surviving corporation (the "Surviving Corporation"), will
        become a wholly-owned subsidiary of the Buyer.

             WHEREAS, the Merger Agreement provides that an escrow
        account will be established to secure the indemnification
        obligations to the Buyer in Article VI of the Merger Agreement on
        the terms and conditions set forth herein.

             WHEREAS, the parties hereto desire to establish the terms
        and conditions pursuant to which such escrow account will be
        established and maintained.

             NOW, THEREFORE, the parties hereto hereby agree as follows:

             1.   Defined Terms.  Capitalized terms used in this
        Agreement and not otherwise defined shall have the meanings given
        them in the Merger Agreement.

             2.   Consent of Company Stockholders.  By virtue of the
        Company Stockholders' approval of the Merger Agreement, and/or by
        their execution of Forms of Election and/or Optionee Consent
        Agreements, Company Stockholders set forth in Schedule I hereto,
        as such schedule may be amended, (the "Indemnifying
        Stockholders") have consented to: (a) the indemnification of the
        Buyer, the Company and the Subsidiaries as set forth in Article
        VI of the Merger Agreement; and (b) their agreement to be bound
        by the terms of this Escrow Agreement and to be a party hereto
        with the same force and effect as if they were a signatory
        hereto, including without limitation (i) the establishment of
        this escrow to secure the indemnification obligations to the
        Buyer under Article VI of the Merger Agreement in the manner set
        forth herein, and (ii) the appointment of the Indemnification
        Representatives as their representatives for purposes of this
        Agreement and as attorneys-in-fact and agents for and on behalf
        of each Indemnifying Stockholder, and the taking by the

        Indemnification Representatives of any and all actions and the
        making of any decisions required or permitted to be taken or made
        by them under this Agreement.

             3.   Escrow and Indemnification.

                  (a)  Escrow of Shares, Warrants and Cash.  On the
        Closing Date, the Buyer shall deposit with the Escrow Agent a
        check issued in the name of the Escrow Agent in the amount of
        Cash Consideration (the "Escrow Cash") and on, but not before,
        January 3, 1996 the Buyer shall deposit with the Escrow Agent
        shares of Buyer Common Stock and Buyer Warrants comprising the
        Merger Units (the "Escrow Units"), which shall be registered in
        the name of the Escrow Agent or its nominee.  The Escrow Units
        and the Escrow Cash are collectively referred to herein as the
        "Escrow Property."  The Buyer may from time to time deposit
        additional Escrow Property with the Escrow Agent, as provided
        under Optionee Consent Agreements being executed by the Buyer and
        certain individuals in connection with the Merger.  The Buyer
        shall be entitled to a pro rata distribution of the Escrow Cash
        to reflect the payment of any amounts to a Dissenting
        Stockholder.  As any such Escrow Property is deposited or
        withdrawn, Schedule I shall be appropriately modified by the
        Indemnification Representative and provided to the Escrow Agent.
        The Escrow Property shall be held as a trust fund and shall not
        be subject to any lien, attachment, trustee process or any other
        judicial process of any creditor of any party hereto.  The Escrow
        Agent agrees to accept delivery of the Escrow Property and to
        hold the Escrow Property in an escrow account (the "Escrow
        Account"), subject to the terms and conditions of this Agreement.

                  (b)  Investment of Escrow Cash.  The Escrow Agent shall
        invest the Escrow Cash as directed in writing by the
        Indemnification Representatives in any of the following:

                       (i)       obligations issued by The United States
        of America or an agency or instrumentality thereof and guaranteed
        by The United States of America;

                       (ii)      certificates of deposit of, or interest
        bearing deposits with, national banks or corporations endowed
        with trust powers, including the Escrow Agent, having capital and
        surplus in excess of $100,000,000;

                       (iii)     commercial paper that at the time of
        investment is rated A-1 by Standard & Poor's Corporation or P-1
        by Moody's Investor Services, Inc.;

                       (iv)      repurchase agreements with any bank or
        corporation described in Section 3(b)(ii) hereof, or registered
        broker-dealers, fully secured by obligations described in Section
        3(b)(i) hereof; or



                                        2

                       (v)       an insured money market account offered
        by the Escrow Agent ("IMMA").

                  (c)  Indemnification.  The Buyer, the Company and the
                       ---------------
        Subsidiaries shall be held harmless from and against specified
        Damages as set forth in Article VI of the Merger Agreement.  The
        Escrow Property shall be security for such indemnity obligation,
        subject to the limitations, and in the manner provided, in this
        Agreement.

                  (d)  Interest, Dividends, Etc.   Any securities, cash
        dividends or property (other than securities) distributable on or
        after January 3, 1996 in respect of or in exchange for any of the
        Escrow Units, whether by way of stock dividends, stock splits or
        otherwise, shall be delivered to the Escrow Agent, who shall hold
        such securities, cash dividends or property (other than
        securities) in the Escrow Account.  Such securities shall be
        issued in the name of the Escrow Agent or its nominee and all
        such securities, cash dividends or property (other than
        securities) shall be considered Escrow Property for purposes
        hereof.  Any interest on the Escrow Cash on or after January 3,
        1996 shall be added to the Escrow Property and for tax reporting
        purposes shall be allocable to the Indemnifying Stockholders.
        Any interest on the Escrow Cash prior to January 3, 1996 shall be
        distributed to and for tax purposes shall be allocable to the
        Buyer.  The Escrow Units shall not be considered as outstanding
        securities of the Buyer for any purpose (including for
        entitlement to dividends) prior to January 3, 1996.  For tax
        purposes, the Escrow Property shall be deemed to be the property
        of the Buyer until January 3, 1996, and all parties hereto shall
        file all their tax returns consistent with such treatment.  The
        parties hereto agree to supply the Escrow Agent with an original,
        signed IRS Form W-9 or its equivalent.

                  (e)  Voting of Shares.  The Indemnification
        Representatives shall have the right, in their sole discretion,
        on behalf of the Indemnifying Stockholders, to direct the Escrow
        Agent in writing as to the exercise of any voting rights
        pertaining to the Escrow Units on or after January 3, 1996, and
        the Escrow Agent shall comply with any such written instructions.
        In the absence of such instructions, the Escrow Agent shall not
        vote any of the Escrow Units.  The Indemnification
        Representatives shall have no obligation to solicit consents or
        proxies from the Indemnifying Stockholders for purposes of any
        such vote. 

                  (f)  Transferability.  The respective interests of the
        Indemnifying Stockholders in the Escrow Property shall not be
        assignable or transferable, other than by operation of law.
        Notice of any such assignment or transfer by operation of law
        shall be given to the Escrow Agent and the Buyer, and no such
        assignment or transfer shall be valid until such notice is given.

             4.   Administration of Escrow Account.  The Escrow Agent
        shall administer the Escrow Account as follows:

                  (a)  If the Buyer, the Company or any Subsidiary has
        incurred or suffered Damages for which it is entitled to
        indemnification under Article VI of the Merger Agreement, it
        shall, prior to the expiration of the representation, warranty,
        covenant or agreement to which such claim relates, give written
        notice of such claim (a "Claim Notice") to the Indemnification
        Representatives and the Escrow Agent.  The Buyer may make a Claim
        Notice only based upon a good faith belief that it has incurred
        Damages for which it is entitled to indemnification under Article
        VI of the Merger Agreement.  Each Claim Notice shall state the
        amount of claimed Damages (the "Claimed Amount") and the basis
        for such claim.  The date on which all of the representations,
        warranties, covenants and agreements of the Company expire in
        accordance with Section 6.5 of the Merger Agreement shall be
        referred to herein as the "Termination Date."

                  (b)  Claims for indemnification involving a claim or
        legal proceeding by a third party shall be made in accordance
        with the procedures set forth in Article VI of the Merger
        Agreement.  For indemnification claims not involving any claim or
        legal proceeding by a third party, the procedures herein shall
        apply.  Within 30 days after delivery of a Claim Notice the
        Indemnification Representatives shall provide to the Buyer, with
        a copy to the Escrow Agent, a written response (the "Response
        Notice") in which the Indemnification Representatives shall:
        (i) agree that Escrow Property having a Fair Market Value (as
        computed pursuant to Section 6) equal to the full Claimed Amount
        may be released from the Escrow Account to the Buyer, (ii) agree
        that Escrow Property having a Fair Market Value equal to part,
        but not all, of the Claimed Amount (the "Agreed Amount") may be
        released from the Escrow Account to the Buyer, or (iii) contest
        that any of the Escrow Property may be released from the Escrow
        Account to the Buyer.  The Indemnification Representatives may
        contest the release of Escrow Property having a Fair Market Value
        equal to all or a portion of the Claimed Amount only based upon a
        good faith belief that all or such portion of the Claimed Amount
        does not constitute Damages for which the Buyer is entitled to
        indemnification under Article VI of the Merger Agreement.  If no
        Response Notice is delivered by the Indemnification
        Representatives within such 30-day period, the Indemnification  
        Representatives shall be deemed to have agreed that Escrow
        Property having a Fair Market Value equal to all of the Claimed
        Amount may be released to the Buyer from the Escrow Account.

                  (c)  If the Indemnification Representatives in the
        Response Notice agree (or are deemed to have agreed) that Escrow
        Property having a Fair Market Value equal to all of the Claimed
        Amount may be released from the Escrow Account to the Buyer, the
        Escrow Agent shall, promptly following the earlier of the
        required delivery date for the Response Notice or the delivery of
        the Response Notice, transfer, deliver and assign to the Buyer

                                        4

<PAGE>





        such amount of Escrow Property held in the Escrow Account which
        has a Fair Market Value equal to the Claimed Amount (or such
        lesser amount of Escrow Property as is then held in the Escrow
        Account).  The relative amount of Escrow Cash and Escrow Units to
        be released shall be determined in accordance with the provisions
        of Section 5 below.

                  (d)  If the Indemnification Representatives in the
        Response Notice agree that Escrow Property having a Fair Market
        Value equal to part, but not all, of the Claimed Amount may be
        released from the Escrow Account to the Buyer, the Escrow Agent
        shall promptly following the delivery of the Response Notice
        transfer, deliver and assign to the Buyer such amount of Escrow
        Property held in the Escrow Account which has a Fair Market Value
        equal to the Agreed Amount (or such lesser amount of Escrow
        Property as is then held in the Escrow Account).  The relative
        amount of Escrow Cash and Escrow Units to be released shall be
        determined in accordance with the provisions of Section 5 below.


                  (e)  If the Indemnification Representatives in the
        Response Notice contest the release of Escrow Property having a
        Fair Market Value equal to all or part of the Claimed Amount (the
        "Contested Amount"), the Indemnification Representatives and the
        Buyer shall attempt promptly and in good faith to agree upon the
        rights of the parties with respect to the Contested Amount.  If
        the Indemnification Representatives and the Buyer should so
        agree, a memorandum setting forth such agreement shall be
        prepared and signed by both parties and the Escrow Agent shall
        transfer, assign and deliver to the Buyer an amount of Escrow
        Property which has a Fair Market Value equal to the amount so
        agreed.  The relative amount of Escrow Cash and Escrow Units to
        be released shall be determined in accordance with the provisions
        of Section 5 below.  If no such agreement can be reached after
        good faith negotiation over a period of 30 days (or such longer
        period as the Buyer and the Indemnification Representatives may
        mutually agree), the matter shall be settled by binding
        arbitration in Boston, Massachusetts.  All claims shall be
        settled by a single arbitrator mutually agreeable to the Buyer
        and the Indemnification  Representatives, or if they cannot agree
        to a single arbitrator in 30 days, by three arbitrators, in
        accordance with the Commercial Arbitration Rules then in effect
        of the American Arbitration Association (the "AAA Rules").  If a
        single arbitrator has not been mutually agreed upon, the
        Indemnification Representatives and the Buyer shall each
        designate one arbitrator within 60 days of the delivery of the
        Indemnification Representatives' Response Notice contesting the
        Claimed Amount.  The Indemnification Representatives and the
        Buyer shall cause such designated arbitrators mutually to agree
        upon and designate a third arbitrator; provided, however, that
        (i) failing such agreement within 90 days of delivery of the
        Indemnification Representatives' Response Notice, the third
        arbitrator shall be appointed in accordance with the AAA Rules,
        and (ii) if either the Indemnification Representatives or the

                                        5
PAGE
<PAGE>





        Buyer fail to timely designate an arbitrator, the dispute shall
        be resolved by the one arbitrator timely designated.  The
        Indemnifying Stockholders and the Buyer shall pay the fees and
        expenses of their respectively designated arbitrators and shall
        bear equally the fees and expenses of the third arbitrator (or of
        the sole arbitrator, in the event a single arbitrator decides the
        matter).  The Indemnification Representatives and the Buyer shall
        cause the arbitrators to decide the matter to be arbitrated
        pursuant hereto within 60 days after the appointment of the last
        arbitrator.  The arbitrators' decision shall relate solely to
        whether the Buyer, the Company and/or the Subsidiary is entitled
        to receive the Contested Amount (or a portion thereof) pursuant
        to the applicable terms of the Merger Agreement and this
        Agreement.  The final decision of the arbitrator, or the majority
        of the arbitrators in the case of three arbitrators, shall be
        furnished to the Indemnification Representatives, the Buyer and
        the Escrow Agent in writing and shall constitute a conclusive
        determination of the issue in question, binding upon the
        Indemnification Representatives, the Indemnifying Stockholders,
        the Buyer, the Company, the Subsidiaries and the Escrow Agent,
        and shall not be contested by any of them.  Such decision may be
        used in a court of law only for the purpose of seeking
        enforcement of the arbitrators' award.

                  (f)  After delivery of a Response Notice that the
        Claimed Amount is contested by the Indemnification
        Representatives, the Escrow Agent shall continue to hold in the
        Escrow Account an amount of Escrow Property having a Fair Market
        Value sufficient to cover the Contested Amount (up to the amount
        of Escrow Property then available in the Escrow Account),
        notwithstanding the occurrence of a release date (as set forth in
        Section 5 below), until (i) delivery of a copy of a settlement
        agreement executed by the Buyer and the Indemnification
        Representatives setting forth instructions to the Escrow Agent as
        to the release of Escrow Property, if any, that shall be made
        with  respect to the Contested Amount, or (ii) delivery of a copy
        of the final award of the arbitrator, or a majority of the
        arbitrators in the case of three arbitrators, setting forth
        instructions to the Escrow Agent as to the release of Escrow
        Property, if any, that shall be made with respect to the
        Contested Amount.  The Escrow Agent shall thereupon release
        Escrow Property from the Escrow Account (to the extent Escrow
        Property is then held in the Escrow Account) in accordance with
        such agreement or instructions.

                  (g)  If, as a result of any third party claim or legal
        proceeding subject to the indemnification procedures set forth in
        the Merger Agreement, any settlement has been entered into, or
        any judgment entered in favor of any third party (which is not
        subject to further appeal), the Buyer, the Company or any
        Subsidiary may give notice of the resulting Damages to the Escrow
        Agent and the Escrow Agent shall, promptly following the receipt
        of such notice, transfer, deliver and assign to the Buyer such
        amount of Escrow Property held in the Escrow Account which has a

                                        6
PAGE
<PAGE>





        Fair Market Value equal to such Damages (or such lesser amount of
        Escrow Property as is then held in the Escrow Account).  The
        relative amounts of Escrow Cash and Escrow Units to be released
        shall be determined in accordance with the provisions of
        Section 5 below.

                  (h)  In the event that, at the time that the Escrow
        Agent is to release any amounts to the Buyer hereunder,
        signatories to Optionee Consent Agreements would be required to
        forfeit certain stock options, the Buyer and the Indemnification
        Representatives agree that they will in good faith determine the
        value of such forfeitures and issue joint written instructions to
        the Escrow Agent identifying an adjustment to be made in the
        amounts of the Escrow Property to be distributed to the Buyer
        hereunder.

             5.   Release of Escrow Property. 

                  (a)  Promptly after January 5, 1996, the Escrow Agent
        shall distribute to the Indemnifying Stockholders Escrow Property
        having a Fair Market Value equal to the difference between (i)
        80% of the Escrow Property initially deposited with the Escrow
        Agent and (ii) any amounts previously distributed from the Escrow
        Fund in payment of any indemnification obligation to the Buyer
        under Article VI of the Merger Agreement (the "Initial
        Distribution").  Notwithstanding the foregoing, if the Buyer has
        previously given a Claim Notice which has not then been resolved
        in accordance with Section 4 or the terms of the Merger Agreement
        (as applicable), the Escrow Agent shall only distribute under
        this subsection 5(a) Escrow Property having a Fair Market Value
        equal to the difference between (x) the Fair Market Value of the
        Initial Distribution, and (y) the Claimed Amount.

                  (b)  Promptly after the first anniversary of the
        Effective Time, the Escrow Agent shall distribute to the
        Indemnifying Stockholders Escrow Property having a Fair Market
        Value equal to the difference between (i) 10% of the Escrow
        Property initially deposited with the Escrow Agent, and (ii) any
        amounts previously distributed from the Escrow Fund in payment of
        any indemnification obligation to the Buyer under Article VI of
        the Merger Agreement, except to the extent such amounts had
        previously reduced the Initial Distribution (the "Second
        Distribution").  Notwithstanding the foregoing, if the Buyer has
        previously given a Claim Notice which has not then been resolved
        in accordance with Section 4 or the Terms of the Merger Agreement
        (as applicable) or otherwise fully reserved for in connection
        with a distribution under subsection 5(a) above, the Escrow Agent
        shall only distribute under this subsection 5(b) Escrow Property
        having a Fair Market value equal to the difference between (x)
        10% of the Fair Market Value of the Escrow Property initially
        deposited with the Escrow Agent, and (y) the Claimed Amount (or
        such portion thereof as has not been fully reserved for in
        connection with a distribution under subsection 5(a) above).

                  (c)  Promptly after the Termination Date, the Escrow
        Agent shall distribute to the Indemnifying Stockholders all of
        the Escrow Property then held in escrow.  Notwithstanding the
        foregoing, if the Buyer has previously given a Claim Notice which
        has not then been resolved in accordance with Section 4 or the
        terms of the Merger Agreement (as applicable), the Escrow Agent
        shall retain in the Escrow Account after the Termination Date an
        amount of Escrow Property having a Fair Market Value equal to the
        Claimed Amount covered by any Claim Notice which has not then
        been resolved.  Any funds so retained in escrow shall be
        disbursed in accordance with the terms of the resolution of such
        claims. 

                  (d)  Any distribution of all or a portion of the Escrow
        Property to the Indemnifying Stockholders shall be made in
        accordance with the percentage interests set forth opposite such
        holders' respective names on Schedule I attached hereto;
        provided, however, (i) that the Escrow Agent shall withhold the
        distribution of the portion of the Escrow Property otherwise
        distributable to Indemnifying Stockholders who have not,
        according to written notice provided by the Buyer to the Escrow
        Agent, prior to such distribution, surrendered their respective
        Certificates pursuant to the terms and conditions of the Merger
        Agreement; (ii) that such Schedule I shall be appropriately
        revised in the event the Buyer deposits additional Escrow
        Property with the Escrow Agent pursuant to the Merger Agreement
        or Optionee Consent Agreements following the date of this
        Agreement; (iii) that Escrow Units shall only be distributed to
        those Indemnifying Stockholders listed in Schedule I as entitled
        to receive Escrow Units (the "Unit Stockholders"); (iv) that,
        with respect to the Initial  Distribution, the Indemnification
        Representatives shall direct the Escrow Agent in writing the
        relative amount of the Escrow Cash and whole Escrow Units to
        distribute to the Unit Stockholders (consistent with the
        provisions of subsection 5(a) hereof); and (v) that Unit
        Stockholders shall thereafter receive Escrow Cash and Escrow
        Units in proportion to the relative Fair Market Value of Escrow
        Cash and Escrow Units held on their behalf in escrow hereunder
        immediately after the Initial Distribution (with any fractional
        Escrow Units rounded down to the next whole Escrow Unit).  Any
        property withheld pursuant to clause (i) above shall be delivered
        to the Buyer promptly after the Termination Date, and shall be
        delivered by the Buyer to the Indemnifying Stockholders to whom
        such property would have otherwise been distributed upon
        surrender of their respective Certificates.  Distributions to the
        Indemnifying Stockholders shall be made by mailing stock
        certificates and Buyer Warrants and/or cash to such holders at
        their respective addresses shown on Schedule I (or such other
        address as may be provided in writing to the Escrow Agent by any
        such holder).  No fractional Escrow Units shall be distributed to
        Indemnifying Stockholders pursuant to this Agreement.  Instead,
        the Buyer shall redeem such Escrow Units for an amount equal to
        their Fair Market Value and the Escrow Agent shall distribute
        cash in lieu thereof.  The Buyer will cooperate with the Escrow

        Agent and will make available certificates for Buyer Common Stock
        and Buyer Warrants in such denominations and in such names as may
        be required to effectuate any distributions hereunder.

             6.   Valuation of Escrow Shares.  For purposes of this
        Agreement, the Fair Market Value of each Escrow Unit shall be
        $49.00, the Fair Market Value of each Warrant shall be $4.00, and
        the Fair Market Value of the Buyer Common Stock shall be $15.00
        per share.

             7.   Fees and Expenses of Escrow Agent.  The Buyer agrees to
        pay or reimburse the Escrow Agent for any legal fees and expenses
        incurred in connection with the preparation of this Agreement and
        to pay the Escrow Agent's reasonable compensation for its normal
        services hereunder in accordance with the attached Schedule II,
        which may be subject to change on an annual basis.  The Escrow
        Agent shall be entitled to reimbursement on demand for all
        expenses incurred in connection with the administration of the
        escrow created hereby which are in excess of its compensation for
        normal services hereunder, including without limitation, payment
         of any legal fees and expenses incurred by the Escrow Agent in
        connection with the resolution of any claim by any party
        hereunder.

             8.   Responsibility of the Escrow Agent.

                  (a)  The Escrow Agent may act upon any instrument or
        other writing believed by it in good faith to be genuine and to
        have been signed or presented by the proper person and shall have
        no responsibility for determining the accuracy thereof.  The
        Escrow Agent shall not be liable to any party hereto in
        connection with the performance of its duties hereunder, except
        for its own gross negligence, bad faith or willful misconduct.
        The Escrow Agent's duties shall be determined only with reference
        to this Agreement and applicable laws and the Escrow Agent is not
        charged with knowledge of, or any duties or responsibilities in
        connection with, any other document or agreement.  If in doubt as
        to its duties and responsibilities hereunder, the Escrow Agent
        may consult with counsel of its choice and shall be protected in
        any action reasonably taken or omitted in connection with the
        advice or opinion of such counsel.

                  (b)  If any party to this Agreement disagrees on
        anything connected with this escrow, (i) the Escrow Agent will
        not have to settle the matter, (ii) the Escrow Agent may wait for
        a settlement by appropriate legal proceedings or other means it
        may require, and in such event it will not be liable for damages,
        (iii) if the Escrow Agent intervenes in or is made a party to any
        legal proceedings, it will be entitled to such reasonable
        compensation for services, costs and attorney's fees as the court
        may award, and (iv) the Escrow Agent is entitled to hold assets
        deposited in escrow hereunder pending settlement of the
        disagreement by any of the above means.

                  (c)  The Escrow Agent is to act as a depository agent
        only and is hereby relieved of any liability in connection with
        any representations made by the other parties hereto or any of
        their agents.  The Escrow Agent shall not be responsible for and
        shall not be under a duty to examine any other agreement.

             9.   Indemnification of Escrow Agent.  Neither the Escrow
        Agent nor any of its directors, officers or employees shall be
        liable to anyone for any action taken or omitted to be taken by
        it or any of its directors, officers or employees hereunder
        except in the case of gross negligence, bad faith or willful
        misconduct.  Buyer and Indemnifying Stockholders, jointly and
        severally, covenant and agree to indemnify the Escrow Agent and
        hold it harmless without limitation from and against any loss,
        liability or expense of any nature incurred by the Escrow Agent
        arising out of or in connection with this Agreement or with the
        administration  of its duties hereunder, including, but not
        limited to, legal fees and expenses and other costs and expenses
        of defending or preparing to defend against any claim of
        liability in the premises, unless such loss, liability or expense
        shall be caused by the Escrow Agent's gross negligence, bad faith
        or willful misconduct.  In no event shall the Escrow Agent be
        liable for indirect, punitive, special or consequential damages.

             10.  Resignation of the Escrow Agent.  The Escrow Agent may
        resign and be discharged from its duties hereunder at any time by
        giving not less than 60 days prior written notice of such
        resignation to the Buyer and the Indemnification Representatives,
        which notice shall specify the date when such resignation shall
        take effect.  Upon such notice, the Buyer and the Indemnification
        Representatives shall jointly appoint a successor to the Escrow
        Agent.  If the Buyer and the Indemnification Representatives are
        unable to agree upon a successor to the Escrow Agent within 30
        days after such notice, the Escrow Agent may apply to a court of
        competent jurisdiction for such appointment.  The Escrow Agent
        shall continue to serve until its successor delivers to the Buyer
        and the Indemnification Representatives a duly executed
        instrument of acceptance of the terms and conditions of this
        Agreement and receives the Escrow Property.  The provisions of
        Section 9 hereof shall survive the resignation or removal of the
        Escrow Agent or the termination of this Escrow Agreement.

             11.  Liability and Authority of Indemnification
        Representatives; Successors and Assignees.

                  (a)  The Indemnification Representatives shall incur no
        liability to the Indemnifying Stockholders with respect to any
        action taken or suffered by them in reliance upon any note,
        direction, instruction, consent, statement or other documents
        believed by them to be genuinely and duly authorized, nor for
        other action or inaction except their own willful misconduct or
        gross negligence.  The Indemnification Representatives may, in
        all questions arising under the Escrow Agreement, rely on the
        advice of counsel and for anything done, omitted or suffered in

                                       10

        good faith by the Indemnification Representatives based on such
        advice, the Indemnification Representatives shall not be liable
        to the Indemnifying Stockholders. 

                  (b)  In the event of the death or permanent disability
        of either Indemnification Representative, or his resignation as
        an Indemnification Representative, a successor Indemnification
        Representative shall be appointed by the other Indemnification
        Representative or, absent such appointment, a successor
        Indemnification Representative shall be elected by a majority
        vote of the Indemnifying Stockholders, with each such
        Indemnifying Stockholder (or his or her successors or assigns) to
        be given a  vote equal to the number of votes represented by the
        Company Shares held by such Indemnifying Stockholder immediately
        prior to the Effective Time.  Each successor Indemnification
        Representative shall have all of the power, authority, rights and
        privileges conferred by this Agreement upon the original
        Indemnification Representatives, and the term "Indemnification
        Representatives" as used herein shall be deemed to include any
        and all successor Indemnification Representatives.

                  (c)  The Indemnification Representatives, acting
        jointly but not singly, shall have full power and authority to
        represent the Indemnifying Stockholders, and their successors,
        with respect to all matters arising under this Agreement and all
        actions taken by any Indemnification Representative hereunder
        shall be binding upon the Indemnifying Stockholders, and their
        successors, as if expressly confirmed and ratified in writing by
        each of them.  Without limiting the generality of the foregoing,
        the Indemnification Representatives, acting jointly but not
        singly, shall have full power and authority to interpret all of
        the terms and provisions of this Agreement, to compromise any
        claims asserted hereunder and to authorize payments to be made
        with respect thereto, on behalf of the Indemnifying Stockholders
        and their successors.  All actions to be taken by the
        Indemnification Representatives hereunder shall be evidenced by,
        and taken upon, the written direction of both of them.

             12.  Amounts Payable by Indemnifying Stockholders.  The fees
        and out-of-pocket expenses incurred by the Indemnifying
        Stockholders in resolving Claim Notices under this Agreement and
        in defending third party claims in connection with Article VI of
        the Merger Agreement shall be payable solely as follows.  The
        Indemnification Representatives shall notify the Escrow Agent of
        any such fees and expenses incurred by the Indemnifying
        Stockholders prior to making payment thereof, with a copy of such
        notice to the Buyer.  On the sixth business day after the
        delivery of such notice, the Escrow Agent shall disburse Escrow
        Cash and the Buyer will redeem the Escrow Units, as is necessary
        to raise an amount necessary to pay such fees and expenses, and
        shall disburse such amounts to the party to whom such amount is
        owed in accordance with the instructions of the Indemnification
        Representatives; provided that if the Buyer delivers to the
        Escrow Agent (with a copy to the Indemnification

                                       11

        Representatives), within five business days after delivery of
        such notice by the Indemnification Representatives, a written
        notice contesting the legitimacy or reasonableness of such fees
        and expenses, then the Escrow Agent shall not make such
        disbursement and such dispute shall be resolved by the Buyer and
        the Indemnification Representatives in accordance with the
        procedures set forth in Section 4(e). 

             13.  Termination.  This Agreement shall terminate upon the
        later of the Termination Date or the distribution by the Escrow
        Agent of all of the Escrow Property in accordance with this
        Agreement.

        via a reputable nationwide overnight courier service.

        units (the "Units") issued by the Company in consideration for
        the acquisition (by merger) of Remediation Technologies, Inc. by
        the Company.  Each individual Unit is comprised of three shares
        of Common Stock and a warrant to purchase one share of Common
        Stock on the terms described below.  This warrant comprises a
        part of a number of Units equal to the number of shares of Common
        Stock set forth above.  This warrant is hereinafter referred to
        as the "Warrant," and the shares purchasable upon exercise of
        this Warrant and the purchase price per share, each as adjusted
        from time to time pursuant to the provisions of this Warrant, are
        hereinafter referred to as the "Warrant Shares" and the "Purchase
        Price," respectively.

             1.   Exercise.

                  (a)  Subject to the termination event and restrictions
        described herein, this Warrant may be exercised by the Registered
        Holder, in whole or in part, by surrendering this Warrant, with
        the purchase form appended hereto as Exhibit A duly executed by
        such Registered Holder or by such Registered Holder's successor
        by will or the laws of descent and distribution, at the principal
        office of the Company, or at such other office or agency as the
        Company may designate, accompanied by payment in full of the
        Purchase Price payable in respect of the number of Warrant Shares
        purchased upon such exercise, either in lawful money of the
        United States or by delivery to the Company of shares of Common
        Stock already owned by the Registered Holder having a fair market
        value equal in amount to such purchase price. 

                  (b)  The Registered Holder may, at its option, elect to
        pay some or all of the Purchase Price payable upon an exercise of
        this Warrant by cancelling a portion of this Warrant exercisable
        for such number of Warrant Shares as is determined by dividing
        (i) the total Purchase Price payable in respect of the number of
        Warrant Shares being purchased upon such exercise by (ii) the
        excess of the Fair Market Value per share of Common Stock as of
        the effective date of exercise, as determined pursuant to
        subsection 1(c) below (the "Exercise Date") over the Purchase
        Price per share.  If the Registered Holder wishes to exercise
        this Warrant pursuant to this method of payment with respect to
        the maximum number of Warrant Shares purchasable pursuant to this
        method, then the number of Warrant Shares so purchasable shall be
        equal to the total number of Warrant Shares, minus the product
        obtained by multiplying (x) the total number of Warrant Shares by
        (y) a fraction, the numerator of which shall be the Purchase
        Price per share and the denominator of which shall be the Fair
        Market Value per share of Common Stock as of the Exercise Date.
        The Fair Market Value per share of Common Stock shall be
        determined as follows:

                       (i)  If the Common Stock is listed on a national
        securities exchange, the NASDAQ National Market System, the
        NASDAQ system or another nationally recognized exchange or
        trading system as of the Exercise Date, the Fair Market Value per
        share of Common Stock shall be deemed to be the last reported
        sale price per share of Common Stock thereon on the Exercise
        Date; or, if no such price is reported on such date, such price
        on the next preceding business day (provided that if no such
        price is reported on the next preceding business day, the Fair
        Market Value per share of Common Stock shall be determined
        pursuant to clause (ii)). 

                       (ii) If the Common Stock is not listed on a
        national securities exchange, the NASDAQ National Market System,
        the NASDAQ system or another nationally recognized exchange or
        trading system as of the Exercise Date, the Fair Market Value per
        share of Common Stock shall be deemed to be the amount most
PAGE
<PAGE>





        recently determined by the Board of Directors to represent the
        fair market value per share of the Common Stock (including
        without  limitation a determination for purposes of granting
        Common Stock options or issuing Common Stock under an employee
        benefit plan of the Company); and, upon request of the Registered
        Holder, the Board of Directors (or a representative thereof)
        shall promptly notify the Registered Holder of the Fair Market
        Value per share of Common Stock.  Notwithstanding the foregoing,
        if the Board of Directors has not made such a determination
        within the three-month period prior to the Exercise Date, then
        (A) the Fair Market Value per share of Common Stock shall be the
        amount next determined by the Board of Directors to represent the
        fair market value per share of the Common Stock (including
        without limitation a determination for purposes of granting
        Common Stock options or issuing Common Stock under an employee
        benefit plan of the Company), (B) the Board of Directors shall
        make such a determination within 15 days of a request by the
        Registered Holder that it do so, and (C) the exercise of this
        Warrant pursuant to this subsection 1(b) shall be delayed until
        such determination is made.

                  (c)  Each exercise of this Warrant shall be deemed to
        have been effected immediately prior to the close of business on
        the day on which this Warrant shall have been surrendered to the
        Company as provided in subsection 1(a) above.  At such time, the
        person or persons in whose name or names any certificates for
        Warrant Shares shall be issuable upon such exercise as provided
        in subsection 1(d) below shall be deemed to have become the
        holder or holders of record of the Warrant Shares represented by
        such certificates.

                  (d)  As soon as practicable after the exercise of this
        Warrant in full or in part, and in any event within 10 days
        thereafter, the Company, at its expense, will cause to be issued
        in the name of, and delivered to, the Registered Holder: 

                       (i)  a certificate or certificates for the number
        of full Warrant Shares to which such Registered Holder shall be
        entitled upon such exercise plus, in lieu of any fractional share
        to which such Registered Holder would otherwise be entitled, cash
        in an amount determined pursuant to Section 3 hereof; and

                       (ii) in case such exercise is in part only, a new
        warrant or warrants (dated the date hereof) of like tenor,
        calling in the aggregate on the face or faces thereof for the
        number of Warrant Shares equal (without giving effect to any
        adjustment therein) to the number of such shares called for on
        the face of this Warrant minus the sum of (a) the number of such
        shares purchased by the Registered Holder upon such exercise,
        plus (b) the number of Warrant Shares (if any) covered by the
        portion of this Warrant cancelled in payment of the Purchase
        Price payable upon such exercise pursuant to subsection 1(b)
        above, plus (c) the  number of Warrant Shares as to which this

<PAGE>





        Warrant has previously been terminated pursuant to Section 2
        below.

             2.   Termination Events.  Notwithstanding the rights
        described in Section 1, upon any disposition, transfer or
        hypothecation by the Registered Holder of any shares of Common
        Stock comprising a portion of any Unit of which this Warrant also
        comprises a part, prior to three years from the Date of Issuance,
         this Warrant shall automatically terminate and be null and void
        with respect to that number of shares of Common Stock determined
        by dividing (x) the number of such shares of Common Stock so
        disposed of, transferred or hypothecated by (y) 3 (the "Factor"),
        with any fraction determined thereby rounded up to the next
        nearest whole number. 

             3.   Adjustments.

                  (a)  If outstanding shares of the Company's Common
        Stock shall be subdivided into a greater number of shares or a
        dividend in Common Stock shall be paid in respect of Common
        Stock, the Purchase Price and the Factor in effect immediately
        prior to such subdivision or at the record date of such dividend
        shall simultaneously with the effectiveness of such subdivision
        or immediately after the record date of such dividend be
        proportionately reduced and increased, respectively.  If
        outstanding shares of Common Stock shall be combined into a
        smaller number of shares, the Purchase Price and the Factor in
        effect immediately prior to such combination shall,
        simultaneously with the effectiveness of such combination, be
        proportionately increased and reduced, respectively.  When any
        adjustment is required to be made in the Purchase Price, the
        number of Warrant Shares purchasable upon the exercise of this
        Warrant shall be changed to the number determined by dividing
        (i) an amount equal to the number of shares issuable upon the
        exercise of this Warrant immediately prior to such adjustment,
        multiplied by the Purchase Price in effect immediately prior to
        such adjustment, by (ii) the Purchase Price in effect immediately
        after such adjustment. 

                  (b)  If there shall occur any capital reorganization or
        reclassification of the Company's Common Stock (other than a
        change in par value or a subdivision or combination as provided
        for in subsection 3(a) above), or any consolidation or merger of
        the Company with or into another corporation, or a transfer of
        all or substantially all of the assets of the Company, then, as
        part of any such reorganization, reclassification, consolidation,
        merger or sale, as the case may be, the Board of Directors of the
        Company shall either provide (i) that lawful provision shall be
        made so that the Registered Holder of this Warrant shall have the
        right thereafter to receive upon the exercise hereof the kind and
        amount of shares of stock or other securities or property which
        such Registered Holder would have been entitled to receive if,  
        immediately prior to any such reorganization, reclassification,
        consolidation, merger or sale, as the case may be, such
PAGE
<PAGE>





        Registered Holder had held the number of shares of Common Stock
        which were then purchasable upon the exercise of this Warrant, or
        (ii) that this Warrant shall become exercisable in full (to the
        extent not previously terminated pursuant to Section 2 above)
        immediately prior to and shall terminate in its entirety to the
        extent not exercised upon, such reorganization, reclassification,
        consolidation, merger or sale (provided that the Registered
        Holder shall be given ten (10) days prior notice of any
        determination by the Board of Directors under this clause (ii)).
        In any such case described in clause (i) above, appropriate
        adjustment (as reasonably determined in good faith by the Board
        of Directors of the Company) shall be made in the application of
        the provisions set forth herein with respect to the rights and
        interests thereafter of the Registered Holder of this Warrant,
        such that the provisions set forth in this Section 3 (including
        provisions with respect to adjustment of the Purchase Price and
        the Factor) shall thereafter be applicable, as nearly as is
        reasonably practicable, in relation to any shares of stock or
        other securities or property thereafter deliverable upon the
        exercise of this Warrant.  

                  (c)  When any adjustment is required to be made in the
        Purchase Price and the Factor, the Company shall promptly mail to
        the Registered Holder a certificate setting forth the Purchase
        Price and the Factor after such adjustment and setting forth a
        brief statement of the facts requiring such adjustment.  Such
        certificate shall also set forth the kind and amount of stock or
        other securities or property into which this Warrant shall be
        exercisable following the occurrence of any of the events
        specified in subsection 3(a) or (b) above. 

             4.   Fractional Shares.  The Company shall not be required
        upon the exercise of this Warrant to issue any fractional shares,
        but shall make an adjustment therefor in cash on the basis of the
        Fair Market Value per share of Common Stock, as determined
        pursuant to subsection 1(b) above.

             5.   Prohibitions on Transfer; Additional Limitations on
        Exercise.

                  (a)  This Warrant may not be assigned or transferred,
        either voluntarily or by operation of law, except by will or the
        laws of descent and distribution, and, may only be exercised by
        the Registered Holder during his lifetime and thereafter may only
        be exercised by the person to whom it is transferred by will or
        the laws of descent and distribution.

                  (b)  This Warrant shall be subject to the requirement
        that if, at any time, counsel to the Company shall determine that
        the listing, registration or qualification of the Warrant Shares
         issuable upon exercise of this Warrant upon any securities
        exchange or under any state or federal law, or the consent or
        approval of any governmental or regulatory body, or that the
        disclosure of non-public information or the satisfaction of any
PAGE
<PAGE>





        other condition is necessary as a condition of, or in connection
        with, the issuance or purchase of Warrant Shares hereunder, this
        Warrant may not be exercised, in whole or in part, unless such
        listing, registration, qualification, consent or approval, or
        satisfaction of such condition shall have been effected or
        obtained on conditions acceptable to the Board of Directors.
        Nothing herein shall be deemed to require the Company to apply
        for or to obtain such listing, registration or qualification, or
        to satisfy such condition.  

                  (c)  Each certificate representing Warrant Shares,
        unless registered pursuant to an effective registration statement
        filed with the Securities and Exchange Commission, shall bear a
        legend substantially in the following form:

             "The securities represented by this certificate have not
        been registered under the Securities Act of 1933, as amended, and
        may not be offered, sold or otherwise transferred, pledged or
        hypothecated unless and until such securities are registered
        under such Act or an opinion of counsel satisfactory to the
        Company is obtained to the effect that such registration is not
        required."

        The foregoing legend shall be removed from the certificates
        representing any Warrant Shares, at the request of the holder
        thereof, at such time as they become eligible for resale pursuant
        to Rule 144(k) under the Act.

             6.   No Impairment.  The Company will not, by amendment of
        its charter or through reorganization, consolidation, merger,
        dissolution, sale of assets or any other voluntary action, avoid
        or seek to avoid the observance or performance of any of the
        terms of this Warrant, but will at all times in good faith assist
        in the carrying out of all such terms and in the taking of all
        such action as may be necessary or appropriate in order to
        protect the rights of the holder of this Warrant against
        impairment.

             7.   Notices of Record Date, etc.  In case:

                  (a)  the Company shall take a record of the holders of
        its Common Stock (or other stock or securities at the time
        deliverable upon the exercise of this Warrant) for the purpose of
        entitling or enabling them to receive any dividend or other
        distribution, or to receive any right to subscribe for or
        purchase any shares of stock of any class or any other
        securities, or to receive any other right; or

                  (b)  of any capital reorganization of the Company, any
        reclassification of the capital stock of the Company, any
        consolidation or merger of the Company with or into another
        corporation (other than a consolidation or merger in which the
        Company is the surviving entity), or any transfer of all or
        substantially all of the assets of the Company; or
PAGE
<PAGE>






                  (c)  of the voluntary or involuntary dissolution,
        liquidation or winding-up of the Company,

        then, and in each such case, the Company will mail or cause to be
        mailed to the Registered Holder of this Warrant a notice
        specifying, as the case may be, (i) the date on which a record is
        to be taken for the purpose of such dividend, distribution or
        right, and stating the amount and character of such dividend,
        distribution or right, or (ii) the effective date on which such
        reorganization, reclassification, consolidation, merger,
        transfer, dissolution, liquidation or winding-up is to take
        place, and the time, if any is to be fixed, as of which the
        holders of record of Common Stock (or such other stock or
        securities at the time deliverable upon the exercise of this
        Warrant) shall be entitled to exchange their shares of Common
        Stock (or such other stock or securities) for securities or other
        property deliverable upon such reorganization, reclassification,
        consolidation, merger, transfer, dissolution, liquidation or
        winding-up.  Such notice shall be mailed at least ten (10) days
        prior to the record date or effective date for the event
        specified in such notice and, in the case of a notice pursuant to
        subsection 7(b) above, shall state whether this Warrant is to be
        assumed by the successor entity or is to terminate prior thereto
        pursuant to subsection 3(b) above.

             8.   Reservation of Stock.  The Company will at all times
        reserve and keep available, solely for issuance and delivery upon
        the exercise of this Warrant, such number of Warrant Shares and
        other stock, securities and property, as from time to time shall
        be issuable upon the exercise of this Warrant.

             9.   Replacement of Warrants.  Upon receipt of evidence
        reasonably satisfactory to the Company of the loss, theft,
        destruction or mutilation of this Warrant and (in the case of
        loss, theft or destruction) upon delivery of an indemnity
        agreement (with surety if reasonably required) in an amount
        reasonably satisfactory to the Company, or (in the case of
        mutilation) upon surrender and cancellation of this Warrant, the
        Company will issue to and in the name of the Registered Holder,
        in lieu thereof, a new Warrant of like tenor.

             10.  Warrant Register.  The Company will maintain a register
        containing the names and addresses of the Registered Holders of
        this Warrant.  Any Registered Holder may change its or his
        address as shown on the warrant register by written notice to the
        Company requesting such change.

             11.  Mailing of Notices, etc.  All notices and other
        communications from the Company to the Registered Holder of this
        Warrant shall be in writing and shall be deemed effective (i)

        telecopy number set forth on the warrant register maintained by
        the Company.  All notices and other communications from the
        Registered Holder of this Warrant to the Company shall be in
        writing and shall be deemed effective (i) upon delivery by hand,
        (ii) two business days after deposit with an express courier
        service for delivery no later than two business days after such
        deposit, addressed to the Company at its principal office set

        the Company and the Registered Holder or Holders of Warrants then
        outstanding representing a majority of the shares of Common Stock
        issuable upon exercise of the Warrants; provided, however, that
        no change, addition, omission or waiver which causes any change
        in or in any way affects or impairs the obligation of the Company
        in respect of the number of shares purchasable or the price per
        share payable upon exercise of this Warrant, or causes any change
        in  this Section 12, shall be made without the written consent of
