EXHIBIT 2(a)


                          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

        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

        commencing at 1:00 p.m. local time on December 8, 1995, or, if

        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        effectively withdrawn or forfeited.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        Corporation Law or effectively withdrawn his demand for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        withdrawn his right to appraisal of Dissenting Shares, then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

        opportunity to direct all negotiations and proceedings with

             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
        Company or such holder) a Form of Election with respect to that
        number of Unit Election Shares determined by multiplying (i) the
        number of  Merger Units, by (ii) a fraction of which the
        numerator shall be the number of Unit Election Shares owned by
        such holder and the denominator shall be the aggregate number of
        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
        Shares convert into the next higher or lower number of whole
        Units. 

             1.9  Exchange of Shares

                  (a)  Each holder of a Certificate, upon proper
        surrender thereof to the Buyer, shall be entitled to receive in
        exchange therefor (subject to any taxes required to be withheld
                                        5

        and in accordance with the procedures set forth in the Escrow
        Agreement) a pro rata share of the Merger Consideration issuable
        pursuant to Section 1.5.  Until properly surrendered, each such
        Certificate shall be deemed for all purposes to evidence only the
        right to receive a portion of the Merger Consideration.  Holders
        of Certificates shall not be entitled to receive Merger
        Consideration out of escrow until the later of (i) January 5,
        1996 and (ii) the date such Certificates have been surrendered to
        the Buyer.  The Buyer will notify the Escrow Agent of those
        Company Stockholders that have tendered Certificates (or
        Affidavits pursuant to Section 1.9(b) below).  The Buyer shall
        transmit certificates representing Buyer Common Stock and Buyer
        Warrants representing the Merger Units within 5 business days of
        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
        to the Certificate alleged to have been lost, stolen or
        destroyed.

             1.10 Dividends.  No dividends or other distributions payable
        to the holders of record of Buyer Common Stock on or after the
        Closing Date and before January 3, 1996 shall be paid to former
        Company Stockholders in respect of Merger Units (which shall not
        be issued until January 3, 1996).  Dividends or other
        distributions payable to the holders of record of Buyer Common
        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
        of Buyer Common Stock on or after January 3, 1996; provided that
        no such person shall be entitled to receive any interest on such
        dividends or other distributions.

             1.11 Escrow.

                  (a)  On the Closing Date, the Buyer shall deliver to
        the Escrow Agent by check or wire transfer funds in the amount of
        the Cash Consideration and on, but not before, January 3, 1996
        the Buyer shall deliver to the Escrow Agent certificates (issued
        in the name of the Escrow Agent or its nominee) representing the
        Buyer Common Stock and the Buyer Warrants comprising the Merger
        Units, for the purpose of securing the indemnification
                                        6
PAGE






        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
        Agreement and of all of the arrangements relating thereto,
        including without limitation the placement of the Merger
        Consideration in escrow and the appointment of the Escrow Agent
        and the Indemnification Representatives pursuant to the terms
        thereof.

             1.12 Options and Warrants.

                  (a)  As of the Effective Time, all options to purchase
        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

        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

        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.

        ERISA Affiliate been obligated to contribute to any

        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.

        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.

        operations or future prospects of the Company and the
        Subsidiaries.  To the knowledge of the Company, there is no

        condition, results of operations or future prospects of the
        Company and the Subsidiaries.

        filed by the Buyer under Section 13 of the Exchange Act with the
        SEC since March 31, 1995.  As of their respective dates, the
        Buyer Reports did not contain any untrue statement of a material
        fact or omit to state a material fact required to be stated
        therein or necessary to make the statements therein, in light of
        the circumstances under which they were made, not misleading.
        The audited financial statements and unaudited interim financial
        statements of the Buyer included in the Buyer Reports (i) comply
        as to form in all material respects with applicable accounting
        requirements and the published rules and regulations of the SEC
        with respect thereto, (ii) have been prepared in accordance with
        GAAP applied on a consistent basis throughout the periods covered
        thereby (except as may be indicated therein or in the notes
        thereto, and in the case of quarterly financial statements, as
        permitted by Form 10-Q under the Exchange Act), (iii) fairly
        present the consolidated financial condition, results of
        operations and cash flows of the Buyer as of the respective dates
        thereof and for the periods referred to therein, and (iv) are
        consistent with the books and records of the Buyer.

             3.6  Absence of Material Adverse Changes.  Since March 31,
        1995, there has not been any material adverse change in the
        assets, business, financial condition or results of operations of
        the Buyer, nor has there occurred any event or development which
        could reasonably be foreseen to result in such a material adverse
        change in the future.

             3.7  Brokers' Fees.  Neither the Buyer nor the Transitory
        Subsidiary has any liability or obligation to pay any fees or
        commissions to any broker, finder or agent with respect to the
        transactions contemplated by this Agreement, except for a fee
        payable by the Buyer to Redloh Associates.

        efforts, to the extent commercially reasonable, to take all
        actions and to do all things necessary, proper or advisable to
        consummate the transactions contemplated by this Agreement;
        provided, however, that notwithstanding anything in this
        Agreement to the contrary, the Buyer shall not be required to
        sell or dispose of or hold separately (through a trust or

                                       30

        otherwise) any assets or businesses of the Buyer or its

        efforts to obtain, at its expense, all such waivers, permits,

        required as a condition to the obligation of any party hereto to
        consummate the Merger and all of the foregoing from Governmental
        Entities, and to effect all such registrations, filings and
        notices with or to third parties required as a condition to the
        obligation of any party hereto to consummate the Merger and all
        of the foregoing with Governmental Entities, as may be required

        Merger and the Merger Consideration (including the Merger Units)
        to and soliciting the written consents of Company Stockholders in
        favor of the adoption of this Agreement (including without
        limitation the matters referred to in Section 1.12 and
        Article VI).  Such materials shall be in the form of a joint
        confidential offering memorandum and information statement (the
        "Offering Memorandum/Information Statement") which shall contain
        the information concerning the Buyer, the Transitory Subsidiary

        consent soliciting written consents from Company Stockholders in
        favor of the Merger and this Agreement. 

                  (b)  Promptly following the execution of this
        Agreement, the Company will circulate to each Company Stockholder
        and each holder of an Option or Warrant the Offering
        Memorandum/Information Statement (which may include by reference,
        materials filed by the Buyer under the Exchange Act previously
        sent to Company Stockholders and holders of Options and Warrants)
        and, pursuant thereto and in accordance with the Delaware General
        Corporation Law, shall solicit the written consents from Company
        Stockholders in favor of the adoption of this Agreement and the
        approval of the Merger.

                  (c)  The Company shall comply with all applicable  
        provisions of and rules under the Securities Act in the
        preparation and distribution of the Offering
        Memorandum/Information Statement and the solicitation of written
        consents thereunder.  Without limiting the foregoing, the Company
        shall ensure that the information in the Offering
        Memorandum/Information Statement relating to the Company or
                                       31

        furnished by the Company in writing for inclusion therein does
        not, as of the date on which it is distributed to Company
        Stockholders, and as of the date of taking of action by written
        consent, contain any untrue statement of a material fact or omit
        to state a material fact necessary in order to make the
        statements made, in light of the circumstances under which they
        were made, not misleading.

                  (d)  The Buyer shall comply with all applicable
        provisions of and rules under the Securities Act and state
        securities laws in the preparation and distribution of the
        Offering Memorandum/Information Statement and the offering and
        issuance of the Merger Units.  Without limiting the foregoing,
        the Buyer shall ensure that the Offering Memorandum/Information
        Statement does not, as of the date on which it is distributed to
        Company Stockholders, and as of the date of the taking of action
        by written consent, contain any untrue statement of a material
        fact or omit to state a material fact necessary in order to make
        the statements made, in light of the circumstances under which
        they were made, not misleading (provided that the Buyer shall not
        be responsible for the accuracy or completeness of any
        information relating to the Company or any other information
        furnished by the Company in writing for inclusion therein). 

                  (e)  The Company, acting through its Board of
        Directors, shall include in the Information Statement the
        recommendation of its Board of Directors that the Company
        Stockholders consent to the adoption of this Agreement and the
        approval of the Merger, and shall otherwise use its best efforts
        to obtain the Requisite Stockholder Approval. 

             4.4  Hart-Scott-Rodino Act.  Each of the Parties has filed
        the Notification and Report Forms and related material required
        to be filed with the Federal Trade Commission and the Antitrust  
        Division of the United States Department of Justice under the
        Hart-Scott-Rodino Act, and each shall use its best efforts to
        obtain an early termination of the applicable waiting period, and
        shall make any further filings or information submissions
        pursuant thereto that may be necessary, proper or advisable;
        provided, however, that the Buyer shall not be obligated to
        respond to formal requests for additional information or
        documentary material pursuant to 16 C.F.R. 803.20 under the
        Hart-Scott-Rodino Act except to the extent it elects to do so in
        its sole discretion.

             4.5  Operation of Business.  Except as contemplated by this
        Agreement, during the period from the date of this Agreement to
        the Effective Time, the Company shall (and shall cause each
        Subsidiary to) conduct its operations in the Ordinary Course of
        Business and in compliance with all applicable laws and
        regulations and, to the extent consistent therewith, use all
        reasonable efforts to preserve intact its current business
        organization, keep its physical assets in good working condition,
        keep available the services of its current officers and employees
                                       32

        others having business dealings with it to the end that its
        goodwill and ongoing business shall not be impaired in any

        foregoing, prior to the Effective Time or termination of this
        Agreement pursuant to Section 7.1 hereof, neither the Company nor
        any Subsidiary shall, without the written consent of the Buyer:

        redeem or repurchase, any stock of any class or any other

        other person or entity;

                  (d)  enter into, adopt or amend any Employee Benefit

        Merger set forth in Article V not being satisfied; or

        foregoing actions.

             4.6  Full Access.  The Company shall (and shall cause each
        Subsidiary to) permit representatives of the Buyer to have full
        access (at all reasonable times, and in a manner so as not to
        interfere with the normal business operations of the Company and
        the Subsidiaries) to all premises, properties, financial and
        accounting records, contracts, other records and documents, and
        personnel, of or pertaining to the Company and each Subsidiary. 

             4.7  Notice of Breaches.  The Company shall promptly deliver
        to the Buyer written notice of any event or development that

        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

        written notice of any event or development that would (i) render
        any statement, representation or warranty of the Buyer or the

        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

             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

        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

        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.

        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
        Company Stockholder from and against all Damages arising out of
        or related to each and all of the following:

                  (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
        agreement, instrument or document contemplated by this Agreement;

                  (c)  any misrepresentation contained in any statement,
        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






        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






        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).

             7.1  Termination of Agreement.  The Parties may terminate

                  (a)  the Parties may terminate this Agreement by mutual
        written consent;

                  (b)  the Buyer may terminate this Agreement by giving
        written notice to the Company in the event the Company is in
        breach, and the Company may terminate this Agreement by giving
        written notice to the Buyer and the Transitory Subsidiary in the
        event the Buyer or the Transitory Subsidiary is in breach, of any
        material representation, warranty or covenant contained in this
        Agreement, and such breach is not remedied within 10 days of
        delivery of written notice thereof;

                  (c)  the Buyer may terminate this Agreement by giving
        written notice to the Company if the Closing shall not have
        occurred on or before December 31, 1995 by reason of the failure
        of any condition precedent under Section 5.1 or 5.2 hereof
        (unless the failure results primarily from a breach by the Buyer
        or the Transitory Subsidiary of any representation, warranty or
        covenant contained in this Agreement);

                  (d)  the Company may terminate this Agreement by giving
        written notice to the Buyer and the Transitory Subsidiary if the
        Closing shall not have occurred on or before December 31, 1995 by
        reason of the failure of any condition precedent under
        Section 5.1 or 5.3 hereof (unless the failure results primarily
        from a breach by the Company of any representation, warranty or
        covenant contained in this Agreement); or

             7.2  Effect of Termination.  If any Party terminates this
        Agreement pursuant to Section 7.1, all obligations of the Parties
        hereunder shall terminate without any liability of any Party to

        breaches of this Agreement).

                                  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.

        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.
