02109, 10:00 a.m. Boston time, on the date hereof or such other time and place
as shall be agreed upon by the Company and the Investors (the "CLOSING DATE").
At the Closing, the Company shall issue and deliver stock certificates
representing the applicable number of shares of Series A Preferred Stock to be
sold by the Company under, and in consideration of the purchase price set forth

"BY-LAWS," respectively), which have been furnished to the Investors by the
Company, are correct and complete at the date hereof, and the Company is not in
violation of any term of its Amended and Restated Certificate of Incorporation
or By-laws. To the Company's knowledge, the Company is not in violation of any
term or provision of any agreement, instrument, judgment, decree, order,
statute, rule or government regulation applicable to it or to which it is a
party, the violation of which would have a Material Adverse Effect.

     2.2   AUTHORIZATION AND NON-CONTRAVENTION. This Agreement and all documents
executed pursuant hereto are valid and binding obligations of the Company,
enforceable in accordance with their terms. The execution, delivery and
performance of this Agreement and all agreements, documents and instruments

the Conversion Shares, have been duly authorized by all necessary corporate
action of the Company. The execution of this Agreement, the sale and delivery of
the Series A Preferred Stock and, upon conversion of the Series A Preferred
Stock, the issuance of the Conversion Shares, and the performance of any
transaction contemplated hereby will not (i) violate, conflict with or result in
a default under any contract or obligation to which the Company is a party or by
which it or its assets are bound, or any provision of the Amended and

                                      - 2 -
<Page>

Restated Certificate of Incorporation or By-laws of the Company, or cause the
creation of any Lien upon any of the material assets of the Company; (ii)
violate or result in a violation of, or constitute a default (whether after the
giving of notice, lapse of time or both) under, any provision of any law,
regulation or rule, or any order of, or any restriction imposed by any court or
other governmental agency applicable to the Company; (iii) require from the
Company any notice to, declaration or filing with, or consent or approval of any
governmental authority or other third party other than pursuant to state
securities or blue sky laws; or (iv) accelerate any obligation under, or give
rise to a right of termination of, any agreement, permit, license or
authorization to which the Company is a party or by which the Company is bound.

     2.3   CORPORATE RECORDS. The corporate record books of the Company
accurately record all corporate action taken by its stockholders, board of
directors, and committees thereof. The copies of the corporate records of the

Preferred Stock, all of which will be issued and outstanding, and (iii)
3,711,372 shares of undesignated preferred stock, par value $.01 per share, none

effect to the transactions contemplated hereby, the outstanding shares of
capital stock of the Company are held beneficially and of record by the persons
identified in SECTION 2.4 OF THE DISCLOSURE SCHEDULE in the amounts indicated
thereon. Except for the Company's 1989 Stock Option Plan, 1990 Stock Option

date hereof 384,000 shares have been issued upon exercise of options granted
under such plan, 722,000 shares are subject to outstanding, unexercised options

DISCLOSURE SCHEDULE sets forth the name of each holder of options, warrants or
rights to purchase Common Stock, the number of shares for which such options,
warrants or rights are exercisable with respect to each holder, along with the
applicable vesting schedule (including any acceleration terms thereof), if any,

otherwise disclosed in SECTION 2.4 OF THE DISCLOSURE SCHEDULE, there are no
outstanding subscriptions, options, warrants, agreements, arrangements or
commitments of any kind for or relating to the issuance, or sale of, or
outstanding securities convertible into or exchangeable for, any shares of
capital stock of any class or other equity interests of the Company. Other than
as set forth in the Amended and Restated Certificate of Incorporation, the
Company has no obligation to purchase, redeem, or otherwise acquire any of its
capital stock or any interests therein. As of the Closing, and after giving
effect to the transactions contemplated hereby, all of the outstanding shares of
capital stock of the Company will have been duly and validly authorized and
issued and will be fully paid and non-assessable and will have been offered,
issued, sold and delivered in compliance

<Page>

with applicable federal and state securities laws and not subject to any
preemptive rights. The Company has duly and validly authorized and reserved
1,288,628 shares of Common Stock for issuance upon conversion of the Series A
Preferred Stock and the shares of Common Stock so issued will, upon such
conversion, be validly issued, fully paid and non-assessable. The relative
rights, preferences and other provisions relating to the Series A Preferred
Stock are as set forth in EXHIBIT B attached hereto. As of the Closing and after
giving effect to the transactions contemplated hereby, except as set forth in
(i) SECTION 2.4 OF THE DISCLOSURE SCHEDULE; (ii) the Amended and Restated
Certificate of Incorporation; (iii) the Stockholders Agreement; or (iv) the

the Company, (y) no rights to have the Company's capital stock registered for
sale to the public in connection with the laws of any jurisdiction and (z) to

voting of the Company's voting securities or restrictions on the transfer of the
Company's capital stock.

     2.5   SUBSIDIARIES, INVESTMENTS. The Company does not have any direct or
indirect Subsidiaries. The Company does not own or have any direct or indirect
interest in or control over any corporation, partnership, joint venture or other
entity of any kind. The term "CONTROL" shall mean the possession, directly or
indirectly, of the power to direct or cause the direction of the management and
policies of a Person, whether through the ownership of voting securities, by
contract or otherwise.

     2.6   FINANCIAL STATEMENTS; PROJECTIONS. Included in SECTION 2.6 OF THE
DISCLOSURE SCHEDULE are (i) the audited balance sheets as of December 31, 1998
and December 31, 1999 and the related statements of income and cash flows for
the fiscal periods then ended, and (ii) the unaudited balance sheet as of
September 30, 2000 (the "BASE BALANCE SHEET"), and the related statements of
income and cash flows for the fiscal period then ended, all of which statements
(including the footnotes and schedules thereto) were prepared in accordance with
generally accepted accounting principles ("GAAP") consistently applied during
the periods covered thereby (except, in the case of the interim statements, for
the absence of footnote disclosures and immaterial customary year-end
adjustments) and fairly present in all material respects the financial condition
of the Company on the dates of such statements and the results of its operations
and cash flows for the periods covered thereby. Nothing has come to the
attention of the Company since the date of the Base Balance Sheet which would
indicate that such financial statements do not fairly present in all material
respects the financial condition of the Company on the dates of such statements
and results of its operations and cash flows for the periods covered thereby.
Included in SECTION 2.6 OF THE DISCLOSURE SCHEDULE are projections for fiscal
years ending December 31, 2000 and December 31, 2001, which represent
management's good faith estimates of the Company's future financial performance
based upon assumptions which management in good faith believes were reasonable
when made and continues to believe to be reasonable as of the date hereof.

     2.7   ABSENCE OF CERTAIN DEVELOPMENTS. Except as set forth in SECTION 2.7
OF THE DISCLOSURE SCHEDULE, since the date of the Base Balance Sheet, there has
been: (a) no material adverse change in the properties, assets, business
condition (financial or otherwise), prospects or results of operations of the
Company; (b) no declaration, setting aside or payment of any dividend or other
distribution (other than the Stockholder Distribution and normal quarterly tax

                                      - 4 -
<Page>

distributions for periods prior to the Closing) with respect to, or any direct
or indirect redemption or acquisition of, any capital stock of the Company; (c)
no waiver of any valuable right of the Company or cancellation of any material
debt or claim held by the Company; (d) no material loan by the Company to any
officer, director, employee or stockholder of the Company, or any agreement or
commitment therefor; (e) no increase, direct or indirect, in the compensation
paid or payable to any officer, director, employee, consultant, agent or
stockholder of the Company (other than salary increases in the ordinary course
of business consistent with past practice which, individually or in the
aggregate, are not material); (f) no material loss, destruction or damage to any
property of the Company, whether or not insured; (g) no labor trouble involving
the Company and no change in the senior management or other key personnel of the
Company or the terms and conditions of their employment; (h) no acquisition or
disposition of any assets (or any contract or arrangement therefor) nor any
other material transaction by the Company otherwise than for fair value in the
ordinary course of business consistent with past practice; or (i) any agreement
or understanding, whether in writing or otherwise, for the Company to take any
of the actions specified in paragraphs (a) through (h).

     2.8   ABSENCE OF UNDISCLOSED LIABILITIES. The Company does not have any
material liabilities or obligations of any nature, whether accrued, absolute,
contingent or otherwise, asserted or unasserted, known or unknown (including,
without limitation, liabilities as guarantor or otherwise with respect to
obligations of others, or liabilities for Taxes due or then accrued or to become
due, regardless of whether claims in respect thereof had been asserted as of
such date), except liabilities or obligations (i) adequately provided for in the
Base Balance Sheet, (ii) incurred by the Company since the date of the Base
Balance Sheet in the ordinary course of business consistent with past practice,
(iii) under the contracts and agreements listed on the Disclosure Schedule, (iv)
incurred in connection with this Agreement, (v) not required under generally
accepted accounting principles to be reflected on the financial statements and
(vi) disclosed in SECTION 2.8 OF THE DISCLOSURE SCHEDULE. For purposes of this
Section 2.8, "material" liability or obligation shall mean a transaction
involving potential commitment or payment by the Company in excess of $150,000.

     2.9   ACCOUNTS PAYABLE; ACCOUNTS RECEIVABLE; BACKLOG.

           (a)  Except as set forth in SECTION 2.9(a) OF THE DISCLOSURE
SCHEDULE, all accounts payable of the Company arose in bona fide arm's-length
transactions in the ordinary course of business and no material account payable
is delinquent by more than sixty (60) days in its payment. Since the date of the
Base Balance Sheet, the Company has paid its accounts - payable in the ordinary
course and in a manner which is consistent with its past practices. As of the
date hereof, the Company has no account payable to any Person which is
affiliated with it or any of its directors, officers, employees or stockholders,
except as set forth in SECTION 2.9(a) OF THE DISCLOSURE SCHEDULE.

           (b)  All of the accounts receivable of the Company arose in bona fide
arm's-length transactions in the ordinary course of business and are valid and
enforceable claims, are not subject to any set-off or counterclaim, and, to the
Company's knowledge, are fully collectible in the normal course of business,
after deducting the allowance for doubtful accounts stated in the Base Balance
Sheet in accordance with generally accepted accounting principles. Since the

dispose of, and bring actions for infringement of, or possesses exclusive
licenses or other rights to use, all Intellectual Property Rights necessary for
the conduct of its business as presently conducted (other than with respect to

knowledge, by any other party thereto and, except as set forth in SECTION 2.14
OF THE DISCLOSURE SCHEDULE, all of the rights of the Company thereunder are

Property Rights granted to it under any such licenses or other agreements. True

requisite power and authority and right to grant the Intellectual Property
Rights purported to be conferred thereby.

granted Intellectual Property Rights to other Persons (including all end-user

default by the Company, and to the Company's knowledge, by any other party

any amendments thereto, have been made available to the Investors. All
agreements, contracts and instruments which contain escrow terms or provisions
with respect to the Company's Intellectual Property Rights, including, without
limitation, the Company's source code, are listed in SECTION 2.14 OF THE

including, without limitation, any former employer or client of any past or
present employees or consultants of the Company. Except as disclosed in SECTION
2.14 OF THE DISCLOSURE SCHEDULE, neither the Company nor to the Company's
knowledge, any of its employees, independent contractors or consultants has any
agreements or arrangements with their former employers or clients relating to
any Intellectual Property Rights of such employers or clients, which interfere
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,
independent contractors and consultants do not violate any agreements or
arrangements which they have with their former employers or clients. The Company

Stock for its own account, for investment only and not with a view to, or any
present intention of, effecting a distribution of such securities or any part

and power under its charter, by-laws or governing partnership or operating

as applicable. This Agreement and each agreement, document and instrument
executed and delivered by each Investor pursuant to or as contemplated by this
Agreement constitute, or when executed and delivered will constitute, valid and
binding obligations of each of the Investors enforceable in accordance with
their respective terms and will not violate or result in a violation of, or
constitute a default (whether after the giving of notice, lapse of time or both)
under, any provision of any law, regulation or rule, or any order of, or any
restriction imposed by any court or other governmental agency applicable to the

reasonable notice and as often as the Investors shall reasonably request, permit
any authorized representative designated by the Investors to visit and inspect
any of its properties, including its books and records (and to make copies and
extracts therefrom), and to discuss its affairs, finances and accounts with its
officers. Each Investor agrees to use, and to use its reasonable best efforts to
insure that its authorized representatives use, the same degree of care as such
Investor uses to protect its own confidential information, any information
furnished to it by the Company which it identifies as being confidential or
proprietary (so long as such information is not in the public domain), except
that such Investor may disclose such proprietary or confidential information to
any partner, employee, affiliate, authorized representative, subsidiary, parent
or prospective transferee of such Investor for the purpose of evaluating its
investment in the Company as long as such partner, employee, affiliate,
authorized representative, subsidiary, parent or prospective transferee is
advised of, and agrees to be bound by, the confidentiality provisions of this
Section 5.10. 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 who had access to such
confidential information from using such information retained as part of their
general skill, knowledge, talent and expertise.

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
of merger or otherwise shall specifically agree to be bound by the terms hereof.
