foregoing referred to herein as a "Material Adverse Effect").
                                   -------- ------- ------

         5.5. Conformity to Law. The Seller has complied in all material

there exist, any violation of any provision of any national, state or local law
or administrative regulation in respect of the Purchased Business or any of the
Acquired Assets, except for any violation that singly or in the aggregate will

         5.6. Title to Acquired Assets. The Seller is the lawful owner of, has
              ------------------------

         hereby will not alter or impair any such right.

                 (b) Neither the Seller, nor to the knowledge of the Seller, the
         other party or parties thereto, is in breach of any agreement or
         license relating to Intangibles, except for any breaches that singly or

         or agreement relating to Intangibles, and to the knowledge of the
         Seller, there is no basis for such claim except in the case of any of
         the foregoing for any claims that individually or in the aggregate will
         not have a Material Adverse Effect. To the knowledge of the Seller, the
         use by the Seller of any Intangibles does not conflict with or infringe
         on the rights of any Person and the Seller has not received any claim
         or written notice from any Person to such effect, except for any
         conflicts, infringements or violations that singly or in the aggregate
         will not have a Material Adverse Effect. To the knowledge of the
         Seller, no third party is infringing, violating or otherwise using, in
         an unauthorized manner, any Intangibles of the Seller relating to the
         Purchased Business, except for any conflicts, infringements or
         violations that singly or in the aggregate will not cause any
         Intangibles to no longer be available to the Seller or otherwise have a
         Material Adverse Effect.

         5.9.     Brokers. The Seller has not retained, utilized or been

the Purchased Business without the prior written consent of Seller, which
consent Seller shall have the right to withhold if such transaction would have a

         indemnification hereunder, the Buyer and the Seller have agreed to use
         predictable dollar thresholds as

                                       11

<PAGE>

         provided in this paragraph (a). Accordingly, the Buyer and the Seller
         agree that with respect to any representation, warranty or covenant
         referred to in Section 12.1(i) or 12.2(i), if such representation,
         warranty or covenant contains a materiality qualification (e.g.
         "material," "materially," "material to the Purchased Business," "in all
         material respects," or similar qualifiers), such materiality
         qualification shall be deemed to have been met, and such
         representation, warranty or covenant shall be deemed to have been
         breached, if the Buyer or the Seller, as applicable, incurs or is
         alleged to have incurred Losses in excess of $5,000 in connection with
         the matter or event to which such representation, warranty or covenant
         relates.

                  (b)   Neither the Seller nor the Buyer shall be liable to the
         other for any Specified Misrepresentation Claim, if the total Losses
         with respect to such Specified Misrepresentation Claim do not exceed
         $5,000 ("Minor Claims").
                  ------------

                  (c)   The Seller shall not be liable to the Buyer for any
         Specified Misrepresentation Claims, unless and until the total Losses
         suffered by the Buyer with respect to all Specified Misrepresentation
         Claims exceeds $100,000, excluding Losses with respect to Minor Claims,
         and then only to the extent of such excess. The Buyer shall not be
         liable to the Seller for any Specified Misrepresentation Claims unless
         and until the total Losses suffered by the Seller with respect to all
         Specified Misrepresentation Claims exceeds $100,000, excluding Losses
         with respect to Minor Claims, and then only to the extent of such
         excess.

                  (d)   The total amount payable under Sections 12.1 or 12.2 by
         either party shall not exceed $500,000 and the provisions of this
         Article 12 shall be the exclusive remedy of the parties.

         12.5.    Claims.
                  ------

                  (a)   Any party seeking indemnification hereunder (the
        "Indemnified Party") shall promptly notify the other party hereto
         -----------------
        obligated to provide indemnification hereunder (the "Indemnifying
                                                             ------------
        Party") of any action, suit, proceeding, demand or breach (a "Claim")
        -----                                                         -----
        with respect to which the Indemnified Party claims indemnification
        hereunder. If such Claim relates to any action, suit, proceeding or
        demand instituted against the Indemnified Party by a third party (a
        "Third Party Claim"), upon receipt of such notice from the Indemnified
         -----------------
        Party, the Indemnifying Party shall be entitled to participate in the
        defense of such Third Party Claim, and if and only if each of the
        following conditions is satisfied, the Indemnifying Party may assume the
        defense of such Third Party Claim, and in the case of such an assumption
        the Indemnifying Party shall have the authority to negotiate, compromise
        and settle such Third Party Claim.

                        (i)   the Indemnifying Party confirms in writing that it
                  is obligated hereunder to indemnify the Indemnified Party with
                  respect to such Third Party Claim;

                        (ii)  the Indemnified Party does not give the
                  Indemnifying Party written notice that it has determined, in
                  the exercise of its reasonable discretion, that matters of
                  corporate or management policy or a conflict of interest make
                  separate representation by the Indemnified Party's own counsel
                  advisable; and

                        (iii) the Indemnifying Party establishes to the
                  reasonable satisfaction of the Indemnified Party that the
                  Indemnifying Party has (and will continue to have) adequate
                  financial resources to satisfy and discharge such action or
                  claim.

                  The Indemnified Party shall retain the right to employ its own
                  counsel and to participate in the

                                       12

<PAGE>

        defense of any Third Party Claim, the defense of which has been assumed
        by the Indemnifying Party pursuant hereto, but the Indemnified Party
        shall bear and shall be solely responsible for its own costs and
        expenses in connection with such participation.

                 (b)  Notwithstanding the foregoing provisions of this Section
        12.5, (i) no Indemnifying Party shall be entitled to settle any Third
        Party Claim without the Indemnified Party's prior written consent unless
        as part of such settlement the Indemnified Party is released in writing
        from all liability with respect to such Third Party Claim and (ii) no
        Indemnified Party shall be entitled to settle any Third Party Claim
        without the Indemnifying Party's prior written consent unless as part of
        such settlement the Indemnifying Party is released in writing from all
        liability with respect to such Third Party Claim.

                 (c)  In the event one party hereunder should have a claim for
        indemnification that does not involve a Third-Party Claim, the party
        seeking indemnification shall promptly send notice of such Claim to the
        other party. If the latter disputes such Claim, such dispute shall be
        resolved by agreement of the parties or by arbitration pursuant to
        Section 14.13.

         12.6.   Method and Manner of Paying Claims; Set-Off. Subject to the
                 -------------------------------------------
Indemnifying Party's right pursuant to Section 12.5 to defend, negotiate,
compromise and settle a Third Party Claim, the amount of any Claim shall be paid
by the Indemnifying Party forthwith on demand. The unpaid balance of a Claim
shall bear interest at the Seller's base rate plus 2% from the date notice
thereof is given by the Indemnified Party to the Indemnifying Party; provided
that the Indemnifying Party shall only be obligated to pay interest on that
portion of such Claim ultimately determined to be owed to the Indemnified Party.
Any amounts owed by the Seller or to the Buyer or one of its Affiliates (whether
under this Agreement or otherwise) may be set off in satisfaction of amounts
owed by the Buyer or one of its Affiliates to the Seller (whether under this
Agreement or otherwise) and vice versa.

         12.7.   Insurance Proceeds.
                 --------- --------

                 (a)  No Indemnified Party shall be obligated to pursue or
        collect from any insurer prior to making a claim for indemnification
        pursuant to this Article 12 and no Indemnifying Party shall be entitled
        to postpone performance of any indemnification obligation under this
        Article 12 while an insurance claim is pending. However, without
        limiting any of the provisions of Sections 12.1 through 12.6, in
        connection with any matter subject to indemnification under this Article
        12, all parties shall cooperate with each other in giving notice of any
        claim to any insurer (including an insurer of an Indemnified Party) and
        shall provide reasonable assistance in the collection of any such claim;
        provided however, that there is no duty to provide notice, cooperate or
        -------- -------
        assist with respect to an Indemnified Party's insurance policies
        (including the Insurance Policies) where the Indemnified Party
        determines in its sole discretion that such notice, cooperation or
        assistance could invalidate any portion of the coverage available under
        such policy or result in the imposition of retroactive premiums or
        prospective premium increases. In addition, if an Indemnified Party
        makes such a determination after it has notified its insurer, it shall
        be entitled to retract such notice.

                 (b)  If an Indemnified Party actually receives insurance
        proceeds, the amount for which such Indemnified Party is entitled to
        indemnification under this Article 12 shall be reduced appropriately. In
        the event an Indemnified Party receives insurance proceeds after being
        paid by the Indemnifying Party with respect to an indemnifiable matter
        under this Article 12) the Indemnified Party will remit such proceeds to
        the Indemnifying Party, up to the amount previously paid by the
        Indemnifying Party with respect to such matter. Nothing in this Section
        12.7 shall be deemed to waive or limit the subrogation rights of any
        insurer.

         14.3. Entire Agreement. This Agreement (including the Exhibits and
               ----------------
Schedules hereto) contains the entire understanding of the parties, supersedes
all prior agreements and understandings relating to the subject matter hereof
and shall not be amended except by a written instrument hereafter signed by all
of the parties hereto.

         14.4. Governing Law. The validity and construction of this Agreement

shall be governed by the internal laws (and not the choice-of-law rules) of the

this Agreement nor the obligations of any party hereunder shall be assignable or
transferable by such party without the prior written consent of the other

Business is sold by Buyer as part of a transaction in which Buyer is selling all
or substantially all of Buyer's assets to an entity that is not an Affiliate of
Buyer, nor such consent be necessary if either party is acquired (directly or
indirectly) by an entity that is not an Affiliate of such party. No such
assignment shall relieve the parties from their obligations under this

                   ----------------------------------------------------------
The representations and warranties of the parties hereto contained in this
Agreement or otherwise made in writing in connection with the transactions
contemplated hereby (in each case except as affected by the transactions
contemplated by this Agreement) shall survive the Closing and the consummation

shall expire on the last day (if any) on which a claim for indemnification may
be made pursuant to Article 12 for a breach thereof.

         14.8      Further Assurances. From time to time, at the request of the
                   ------------------
 Buyer and without further consideration, the Seller shall execute and
deliver such further instruments of conveyance and transfer and take

                                       15

<PAGE>

such other actions as the Buyer may reasonably require more effectively to
convey and transfer any of the Acquired Assets to the Buyer. The Seller and the
Buyer shall also execute and deliver to the appropriate other party such other
instruments as may be reasonably required in connection with the performance
this Agreement and each shall take all such further actions as may be reasonably
required to carry out the transactions contemplated by this Agreement.

         14.9.  No Implied Rights or Remedies. Except as otherwise expressly
                -----------------------------
provided herein, nothing herein expressed or implied is intended or shall be
construed to confer upon or to give any person, firm or corporation, except the
Seller and the Buyer, any rights or remedies under or by reason of this
Agreement.

         14.10. Counterparts. This Agreement maybe executed in multiple
                ------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         14.11. Public Statements or Releases. The parties hereto each agree
                -----------------------------
that both prior to and following the consummation of the Closing, no party to
this Agreement will make, issue or release any public announcement, statement or
acknowledgment of the existence of, or reveal the status of; this Agreement or
the transactions provided for herein, without first obtaining the consent of the
other parties hereto to the form of such announcement or statement. Nothing
contained in this Section 14.11 shall prevent any party from making such public
announcements as such party may consider necessary in order to satisfy such
party's legal or contractual obligations or to satisfy the closing conditions
contained herein.

         14.12. Dispute Resolution.
                ------------------

         (a)      In the event that there is a dispute or claim (a "dispute")
between the parties hereto in any way relating to this Agreement or the
acquisition by the Buyer of the Purchased Business, then the complaining party
shall initially give written notice to the other party setting forth the
particulars of such dispute in reasonable detail (a "Dispute Notice"). Following
the receipt of such Dispute Notice, a designated executive of each party shall
negotiate in good faith with its designated counterparty with a view to reaching
an agreement with respect to the dispute referred to in such Dispute Notice. If
following 90 calendar days after the receipt of such Dispute Notice such
executives are unable to reach an agreement with respect to such dispute, such
dispute shall be settled by arbitration before a panel of three arbitrators
(with one designated by the Buyer and one designated by the Seller, and the
third arbitrator designated by the first two) pursuant to the rules of the
American Arbitration Association. Any arbitrator designated by the Buyer or the
Seller must be an "Independent Person." For the purposes of this Section 14.12,
an "Independent Person" shall be an individual who is not and has not been (i) a
    ----------- ------
director, officer, employee, agent or shareholder of any party hereto, (ii) a
consultant to any party hereto, (iii) a person with a direct or indirect
financial interest in any contract with either party hereto, (iv) a director,
officer or key employee of a company at a time when such company was party to a
contract with either party hereto, or (v) a relative of any person referred to
in clauses (i), (ii), (iii) or (iv) above. As used in the immediately preceding
sentence, the term "any party hereto" shall be deemed to include any Affiliates
of the parties hereto. Any such arbitration shall take place in Boston, MA.
Arbitration may be commenced at any time by either party hereto giving written
notice to the other party hereto that such dispute has been referred to
arbitration under this Section 14.12. The third arbitrator shall be selected as
prescribed above, but if the first two arbitrators do not so agree within 30
days after the date of the notice referred to above, the selection shall be made
pursuant to the rules of the American Arbitration Association from the
Commercial Arbitration Panel (and not the Construction Arbitration Panel)
maintained by such Association Any award rendered by the arbitrators shall be
conclusive and binding upon the parties hereto; provided, however, that any such
                                                --------  -------
award shall be accompanied by a written opinion of the arbitrators giving the
reasons for the award. In making such award, the arbitrators shall be authorized
to award interest on any amount awarded. This provision for arbitration shall be
specifically enforceable by the Seller and the Buyer and, except as otherwise
set forth below, the decision of the arbitrators in accordance herewith shall be

                                       16

<PAGE>

final and binding. Either party to an arbitration may petition the court in
Massachusetts to confirm, correct or vacate the award on the grounds stated in
the Federal Arbitration Act, or to enter judgment on the arbitration award. Each
of the Seller and the Buyer shall pay its own expenses of arbitration and the
expenses of the arbitrators shall be equally shared; provided, however, that if
                                                     --------  -------
in the opinion of the arbitrators any claim for indemnification or any defense
or objection thereto was frivolous or in bad faith, the arbitrators may assess,
as part of the award, all or any part of the arbitration expenses of the other
party (including reasonable attorneys' fees) and of the arbitrators against the
party raising such unreasonable claim, defense or objection.

         (b) To the extent that arbitration may not be legally permitted
hereunder and the Seller and the Buyer do not at the time of such dispute or
claim mutually agree to submit such dispute or claim to arbitration either the
Seller or the Buyer may commence a civil action in a court of appropriate
jurisdiction to solve disputes or claims hereunder. Nothing contained in this
Section 14.12 shall prevent the Seller and the Buyer from settling any dispute
or claim by mutual agreement at any time.

                  (c) Neither party shall be precluded hereby from seeking, from
the courts of any jurisdiction, provisional or equitable remedies of a type not
available in arbitration, including without limitation, temporary restraining
orders and preliminary or permanent injunctions, nor shall the pursuit of such
provisional or equitable relief constitute a waiver or modification of such
party's right and obligation to arbitrate any related or unrelated dispute which
is otherwise subject to arbitration under this Agreement, unless such waiver is
expressed in writing and signed by such party. In the event any person not a
party to this Agreement shall commence any interpleader or similar action which
either directly or indirectly raises issues which are subject to arbitration
hereunder, the Seller and the Buyer shall seek a stay of such proceedings
pending arbitration in accordance with this Agreement.

                  (d) In the event of any Third Party Claim where the
Indemnifying Party does not assume the defense of such Third Party Claim,
nothing in this Section 14.12 shall prevent the Indemnified Party from
impleading the Indemnifying Party or otherwise joining the Indemnifying Party to
any litigation relating to such Third Party Claim.

         14.14. Construction. The language used in this Agreement will be deemed
                ------------
to be the language chosen by the parties to express their mutual intent, and no
rule of strict construction will be applied against any party.
