or conflict with the performance of such employee's, independent contractor's or
consultant's duties for the Company or result in any former employers or clients
of such employees, independent contractors or consultants having any rights in,
or claims on, the Company's Intellectual Property Rights. To the Company's
knowledge, after due inquiry, the activities of the Company's employees,

proprietary (so long as such information is not in the public domain), except
that such Investor may disclose such proprietary or confidential information to

information; or (ii) prevent such Investor's employees who had access to such

SECTION 6 SURVIVAL; INDEMNIFICATION

     6.1   SURVIVAL OF REPRESENTATIONS WARRANTIES AND COVENANTS. All covenants,
agreements, representations and warranties of the Company and the Investors made
herein and in the certificates, lists, exhibits, schedules or other written
information delivered or furnished to any Investor in connection herewith (a)
are material, shall be deemed to have been relied upon by the party or parties
to whom they are made and shall survive the Closing regardless of any

                                     - 23 -
<Page>

investigation on the part of such party or its representatives, and (b) shall
bind the parties' successors and assigns (including, without limitation, any
successor to the Company by way of acquisition, merger or otherwise), whether so
expressed or not, and, except as otherwise provided in this Agreement, all such
covenants, agreements, representations and warranties shall inure to the benefit
of the Investors' successors and assigns and to their transferees, whether so
expressed or not.

     6.2   INDEMNIFICATION FOR VICARIOUS LIABILITY.

           (a)  Without limitation of any other provision of this Agreement, the
Company agrees to defend, indemnify and hold each Investor, their affiliates and
their respective direct and indirect partners, members, stockholders, directors,
officers, employees, agents and representatives and each Person who controls any
of them within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act (collectively, the "INDEMNIFIED PARTIES" and each individually,
an "INDEMNIFIED PARTY") harmless from and against any and all losses, claims,
damages, obligations, liens, assessments, judgments, fines, liabilities and
other costs and expenses, including, without limitation, interest, penalties and
any investigation, legal and other expenses incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claim
asserted, as the same are actually incurred by the Indemnified Parties, of any
kind or nature whatsoever which may be sustained or suffered by any such
Indemnified Party, in their capacity as or as a result of any action taken or
omitted to be taken by them as a director, stockholder, representative or
controlling person of the Company, without regard to any investigation by any of
the Indemnified Parties, based upon, arising out of, by reason of or otherwise
in respect of or in connection with third party or governmental claims under the
Securities Act, the Exchange Act or other federal or state statutory law or
regulation, at common law or otherwise ("LAWS", including, without limitation,
any third party or governmental claim alleging so-called control person
liability or securities law liability ("INDEMNIFIABLE CLAIMS"); PROVIDED,
HOWEVER, that the Company will not be liable to the extent that such loss,
claim, damage, expense or liability arises from and is based on (A) an untrue
statement or omission or alleged untrue statement or omission in a registration
statement or prospectus which is made in reliance on and in conformity with
written information furnished to the Company in an instrument duly executed by
or on behalf of such Indemnified Party specifically stating that it is for use
in the preparation thereof, (B) a knowing and willful violation of any Law or
Laws by an Indemnified Party as finally determined by a court of competent
jurisdiction or (C) a fraudulent act or omission by the Indemnified Party as
finally determined by a court of competent jurisdiction.

           (b)  If the indemnification provided for in Section 6.2(a) above for
any reason (other than for any reason specified in items (A), (B), and (C) of
the proviso in Section 6.2(a)) is held by a court of competent jurisdiction to
be unavailable to an Indemnified Party in respect of any losses, claims,
damages, expenses or liabilities referred to therein, then the Company, in lieu
of indemnifying such Indemnified Party thereunder, shall contribute to the
amount paid or payable by such Indemnified Party as a result of such losses,
claims, damages, expenses or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Investors, or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company and the Investors in

                                     - 24 -
<Page>

connection with the action or inaction which resulted in such losses, claims,
damages, expenses or liabilities, as well as any other relevant equitable
considerations. In connection with any registration of the Company's securities,
the relative benefits received by the Company and the Investors shall be deemed
to be in the same respective proportions that the net proceeds from the offering
(before deducting expenses) received by the Company and the Investors, in each
case as set forth in the table on the cover page of the applicable prospectus,
bear to the aggregate public offering price of the securities so offered. The
relative fault of the Company and the Investors shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company and the Investors and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     Each of the Company and the Investors agrees that it would not be just and
equitable if contribution pursuant to this Section 6.2(b) were determined by pro
rata or per capita allocation or by any other method of allocation which does
not take account of the equitable considerations referred to in the immediately
preceding paragraph. In connection with the registration of the Company's
securities, in no event shall an Investor be required to contribute any amount
under this Section 6.2(b) in excess of the proceeds received by such Investor
from its sale of securities under such registration statement. No person found
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not found guilty of such fraudulent misrepresentation.

           (c)  Promptly after receipt by an Indemnified Party of any
Indemnifiable Claim, the Indemnified Party shall give notice thereof in writing
to the Company: PROVIDED, HOWEVER, the failure to give such notice shall not
relieve the Company from its obligations under this Section 6.2 except to the
extent that the Company shall have been materially and adversely prejudiced as a
result of the failure or delay in giving such notice. In any proceeding
involving an Indemnifiable Claim, the Company shall control the defense thereof;
PROVIDED that, the Indemnified Party shall have the right to retain its own
counsel at its own expense. Notwithstanding the foregoing, the Company shall pay
as incurred the fees and expenses of the counsel retained by the Indemnified
Party in the event that (i) the Company and the Indemnified Party shall have
mutually agreed to the retention of such counsel or (ii) the named parties to
any such proceeding (including any impleaded parties) include both the Company
and the Indemnified Party and representation of both parties by the same counsel
would be inappropriate due to actual or potential differing interests between
them.

     The Company shall not, without the prior written consent of the Indemnified
Party, consent to the entry of any judgment against the Indemnified Party or
enter into any settlement or compromise which (i) includes an admission of fault
of the Indemnified Party or (ii) does not include, as an unconditional term
thereof, the full release of the Indemnified Party from all liability in respect
of such Indemnifiable Claim, which release shall be in form and substance
reasonably satisfactory to the Indemnified Party.

           (d)  The indemnification and contribution provided for in this
Section 6.2 will remain in full force and effect regardless of any investigation
made by or on behalf of the Indemnified Parties or any officer, director,
partner, member, employee, agent or controlling

                                     - 25 -
<Page>

person of the Indemnified Parties. The provisions of this Section 6.2 are in
addition to and shall supplement those set forth in any other agreement between
the Company and the Investors.

           (e)  Notwithstanding anything to the contrary herein, the Company
agrees to pay and hold the Investors harmless against liability for payment of
all reasonable fees and disbursement of counsel in connection with the
enforcement, amendment, modification or waiver of this Agreement and the
agreements, documents and instruments contemplated and executed pursuant hereto.

     6.3   ATTORNEYS' FEES. In the event that any suit or action is instituted
to enforce any provision in this Agreement or the agreements, documents and
instruments contemplated hereby and executed pursuant hereto, the prevailing
party in such dispute shall be entitled to recover from the losing party all
fees, costs and expenses of enforcing any right of such prevailing party under
or with respect to this Agreement and the agreements, documents and instruments
contemplated hereby and executed pursuant hereto, including without limitation,
such reasonable fees and expenses of attorneys and accountants, which shall
include, without limitation, all fees, costs and expenses of appeals.

     8.7   DISPUTE RESOLUTION.

           (a)  All disputes, claims, or controversies arising out of or
relating to this Agreement or any other agreement executed and delivered
pursuant to this Agreement or the negotiation, validity or performance hereof
and thereof or the transactions contemplated hereby and thereby that are not
resolved by mutual agreement shall be resolved solely and exclusively by binding
arbitration to be conducted before the American Arbitration Association ("AAA").
If AAA ceases operations, then the parties shall select a comparable
organization that provides qualified arbitration services. The arbitration shall
be held in Boston, Massachusetts before a single arbitrator and shall be
conducted in accordance with the rules and regulations promulgated by AAA unless
specifically modified herein.

     The parties covenant and agree that the arbitration hearing shall commence
within ninety (90) days after the date on which a written demand for arbitration
is filed by any party hereto. In

                                     - 29 -
<Page>

connection with the arbitration proceeding, the arbitrator shall have the power
to order the production of documents by each party and any third-party
witnesses. In addition, each party may take up to three (3) depositions as of
right, and the arbitrator may in his or her discretion allow additional
depositions upon good cause shown by the moving party. However, the arbitrator
shall not have the power to order the answering of interrogatories or the
response to requests for admission. In connection with any arbitration, each
party shall provide to the other, no later than seven (7) business days before
the date of the arbitration hearing, the identity of all persons that may
testify at the arbitration and a copy of all documents that may be introduced at
the arbitration hearing or considered or used by a party's witness or expert.
The arbitrator's decision and award shall be made and delivered within three (3)
months of the selection of the arbitrator. The arbitrator's decision shall set
forth a reasoned basis for any finding of liability or award of damages. The
arbitrator shall not have power to award damages in excess of actual
compensatory damages and shall not multiply actual damages or award punitive
damages or any other damages that are specifically excluded under this
Agreement, and each party hereby irrevocably waives any claim to such damages.

     The parties covenant and agree that they will participate in the
arbitration in good faith and that they will share equally its costs, except as
otherwise provided herein. The arbitrator may in his or her discretion assess
fees and costs (including the reasonable legal fees and expenses of the
prevailing party whether claimant or respondent) against any party to a
proceeding. Any party failing or refusing to comply with an order of the
arbitrators shall be liable for costs and expenses, including attorneys' fees,
incurred by the other party in enforcing the award. Nothing in this Section 8.7
shall prohibit any party from proceeding in court without prior arbitration for
the limited purpose of seeking injunctive relief to avoid immediate and
irreparable harm. The provisions of this Section 8.7 shall be enforceable in any
court of competent jurisdiction.

           (b)  Each of the parties hereto irrevocably and unconditionally
consents to the exclusive use of AAA to resolve all disputes, claims or
controversies arising out of or relating to this Agreement or any other
agreement executed and delivered pursuant to this Agreement or the negotiation,
validity or performance hereof and thereof or the transactions contemplated
hereby and thereby and further consents to the jurisdiction of the federal
and/or state courts in The Commonwealth of Massachusetts for the purposes of
enforcing the arbitration provisions of Section 8.7(a) of this Agreement. Each
party Rather irrevocably waives any objection to proceeding before AAA based
upon lack of personal jurisdiction or to the laying of venue and further
irrevocably and unconditionally waives and agrees not to make a claim in any
court that arbitration before AAA has been brought in an inconvenient forum.
Each of the parties hereto hereby consents to service of process by registered
mail at the address to which notices are to be given. Each of the parties hereto
agrees that its or his submission to jurisdiction and its or his consent to
service of process by mail is made for the express benefit of the other parties
hereto.

     8.8   REMEDIES, SEVERABILITY. Notwithstanding Section 8.7, it is
specifically understood and agreed that any breach of the provisions of this
Agreement by any person subject hereto will result in irreparable injury to the
other parties hereto, that the remedy at law alone will be an inadequate remedy
for such breach, and that, in addition to any other remedies which they may
have, such other parties may enforce their respective rights by actions for
specific performance in the federal or state courts in The Commonwealth of
Massachusetts (to the extent permitted by law). Whenever possible, each
provision of this Agreement shall be interpreted in

                                     - 30 -
<Page>

such a manner as to be effective and valid under applicable law, but if any
provision of this Agreement shall be deemed prohibited or invalid under such
applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, and such prohibition or invalidity shall not
invalidate the remainder of such provision or the other provisions of this
Agreement.

     8.9   INTEGRATION. This Agreement, including the exhibits, schedules,
documents and instruments referred to herein, constitutes the entire agreement,
and supersedes all other prior agreements and understandings, both written and
oral, among the parties with respect to the subject matter hereof, including,
without limitation, the letter of intent dated September 28, 2000 among the
Investors and the Company in respect of the transactions contemplated herein.

     8.10  CONFIDENTIALITY. Each Investor agrees that it will keep confidential
and will not disclose, divulge or use for any purpose other than to monitor its
investment in the Company any confidential, proprietary or secret information
which such Investor may obtain from the Company pursuant to financial
statements, reports and other materials submitted by the Company to such
Investor pursuant to this Agreement, or pursuant to visitation or inspection
rights granted hereunder ("CONFIDENTIAL INFORMATION"), unless such Confidential
Information is known, or until such Confidential Information becomes known, to
the public (other than as a result of a breach of this Section 8.10 by such
Investor); PROVIDED, HOWEVER, that an Investor may disclose Confidential
Information (i) to its attorneys, accountants, consultants, and other
professionals to the extent necessary to obtain their services in connection
with monitoring its investment in the Company, (ii) to any prospective purchaser
of any Series A Preferred Stock from such Investor as long as such prospective
purchaser agrees to be bound by the provisions of this Section 8.10, (iii) to
any Affiliate of such Investor or to a partner, employee, authorized
representative, stockholder or subsidiary of such Investor for the purposes of
monitoring and evaluating its investment in the Company or (v) as may otherwise
be required by law, provided that the Investor takes reasonable steps to
minimize the extent of any such required disclosure. Notwithstanding anything
herein to the contrary, it is expressly understood and agreed that access by an
Investor to any such Confidential Information of the Company shall not (i)
preclude an individual who has seen such Confidential Information from working
on similar investment opportunities for such Investor, provided that such
individual does not make reference to such Confidential Information and does not
divulge the substance of such Confidential Information, or (ii) prevent such
Investor's employees or partners who had access to such Confidential Information
from using such information retained as part of their general skill, knowledge,
talent and expertise.

     8.11  SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
shall inure to the benefit of the respective successors and assigns of the
parties hereto as contemplated herein, and any successor to the Company by way
