     substantially equal or proportionate basis), the relocation of the
     Company's primary place of business or the relocation of Executive by the

     Massachusetts, or the Company's willful, material violation of its
     obligations under this Agreement, in each case, after 60 days' prior

     Pledge Agreement, the Recourse Promissory Note, any other agreement between
     the Executive, on the one hand, and the Company or its affiliates, on the

     PROVIDED, that the Executive has been given written notice describing any
     such violation in reasonable detail and fails to cure the violation within
     90 days from such notice; or

         (iv)  Executive engages in egregious misconduct involving serious moral
     turpitude to the extent that Executive's credibility and reputation no
     longer conform to the standard of the Company's executives.

     (e) For the purposes of this SECTION 3, "MATERIAL BREACH" shall mean any of
the following:

         (i)   Executive's breach of any of his fiduciary duties to the Company
     or its stockholders or making of a willful misrepresentation or omission

         (iii) Executive's habitual drunkenness or substance abuse which
     materially interferes with Executive's ability to discharge his duties,
     responsibilities or obligations prescribed by this Agreement or any other
     agreement between the Executive and the Company; and

         (iv)  Executive's willful and material violation of any
     non-competition, non-disparagement, or confidentiality agreement with the
     Company, including without limitation, those set forth in SECTIONS 7, 8 and
     9 of this Agreement, or any other agreements with the Company.

in each case, for purposes of clauses (i) through (iv), after the Company or the
Board of Directors has provided Executive with 60 days' written notice
describing such circumstances and the possibility of a Material Breach in
reasonable detail, and Executive fails to cure such circumstances and Material
Breach within those 60 days. No act or omission shall be deemed willful if done,
or omitted to be done, in good faith by the Executive based upon a resolution
duly adopted by the Company's Board of Directors.

     (f) In the event Executive's employment is terminated by the Company under
any circumstances described in SECTION 3(b)(v) or by Executive under the
circumstances described in SECTION 3(c)(iii) or(iv), the Company will pay to
Executive the full amounts to which he would be entitled as base compensation
under SECTION 4(a) and customary benefits through the Term of Employment prior
to the application of any early termination provision of SECTION 3(b) or (c). In
the event Executive's employment is terminated by the Company under the
circumstances described in SECTION 3(b)(iv), the Company will pay to Executive
(i) the full amounts to which he would be entitled as base compensation under
SECTION 4(a) and (ii) customary benefits, in each case for the period from the
effectiveness of termination through the date three months after the date of
such termination. In the event Executive's employment is terminated by the
Company under the circumstances described in SECTION 3(b)(i) or (ii) or by the
Executive under SECTION 3(c)(i) or (ii), the Company will pay to the Executive
the full amounts to which he would be entitled as base compensation under
SECTION 4(a) and customary benefits for the period from the effectiveness of
termination through (y) the first anniversary of the date of such termination,
or (z) the third anniversary of the date of this Agreement, whichever is
greater. In the event Executive's employment is terminated by the Company under
any circumstances described in SECTION 3(b)(iii) or by Executive as a result of
resignation or voluntary termination due to any circumstance other than the
material reductions or violations described in SECTION 3(c)(iii) above, there
will be no amounts owing by the Company to the Executive, under SECTION 4 or any
other part of this Agreement, from and after the effectiveness of termination.
If the Company makes the payments required by this SECTION 3(f), such payments
will constitute severance and liquidated damages, and the Company will not be
obligated to pay any further amounts to Executive under this Agreement or
otherwise be liable to Executive in connection with any termination.

     (g) All determinations pursuant to this SECTION 3 shall be made by the
Company's Board of Directors (not including Executive) in good faith.

     (h) Termination of the Term of Employment will not terminate SECTIONS 7,
through 9 and 11 through 21, or any other provisions not associated specifically
with the Term of Employment.

     (i) In the event the Term of Employment is terminated and the Company is
obligated to make payments pursuant to SECTION 3(f), the Executive will use his
reasonable efforts to seek and obtain alternative employment; PROVIDED, HOWEVER,
that the Executive shall not be required to accept a position of a substantially
different character than the position held by him with the Company; and PROVIDED
FURTHER, if the Executive shall become physically or mentally disabled, he will
not be under such duty. If Executive thereafter obtains alternative employment,
then if and to the extent Executive obtains such employment, the Company's
payment obligations under SECTION 3(f), including its obligation to provide
insurance coverage, if any, will be mitigated and reduced by and to the extent
of Executive's compensation under such alternative employment during the period
for which payments are owed by the Company pursuant to SECTION 3(f). Moreover,
in the event that after the Restricted Period pursuant to SECTION 8(a),
Executive is employed by or engaged in a Competitive Business as contemplated by
SECTION 8(a)(i), then the Company will thereupon cease, and will be no longer
obligated, to make payments under SECTION 3(f).

     (j) In the event the Term of Employment is terminated and the Company is
obligated to make payments pursuant to SECTION 3(f), Executive hereby waives any
and all claims against the Company, and its officers, directors, employees,
agents, or representatives, stockholders and affiliates relating to this
Agreement and to his employment during the term hereof other than any payments
to be made pursuant to SECTION 3(f), the Management Subscription Agreement, and
any Company employee benefit plan.

     4.  COMPENSATION. The Company shall pay compensation to Executive as
follows:

     (a) During the Term of Employment, the Company shall pay to Executive as
base compensation for his services hereunder, in monthly installments, a base
salary at a rate of $181,656 per annum, as increased on an annual basis to
reflect the increase in the United States Cost of Living Index for All Urban
Consumer (CPI-U) for the Boston, Massachusetts area (the "CPI-U INDEX"). The
January 2001 CPI-U Index shall provide the basis for calculations of such
increases. Notwithstanding the minimum increase set forth above, the Board of
Directors, in its sole discretion, may establish a higher compensation level.

     (b) During the Term of Employment, the Company shall pay to Executive an
annual bonus based on Executive's performance, as determined and approved by the
Board of Directors in its sole discretion. Such bonus will be at the full
discretion of the Board of Directors, and may not be paid at all. Executive
acknowledges that no bonus has been agreed upon or promised. If the Board of
Directors decides to pay a bonus, it is to be paid within 30 days after the
issuance of audited financial statements for the Company. The Board of Directors
in its sole discretion may establish a higher bonus level based on the
performance of Executive.

the Merger Agreement, on March 31, 2002, the Company shall pay Executive a
transaction bonus of $45,785.

     5.  REIMBURSEMENT OF EXPENSES

     During the Term of Employment, the Company shall reimburse Executive for
documented travel, entertainment and other expenses reasonably incurred by
Executive in connection with the performance of his duties hereunder and, in
each case, in accordance with the rules, customs and usages promulgated by the
Company from time to time in effect.

     6.  BENEFITS. During the Term of Employment, the Executive shall be
entitled to perquisites, paid vacations and benefits (including health, short
and long term disability, pension and life insurance benefits consistent with
past practice, or as increased from time to time) established from time to time,
by the Board of Directors for executives of the Company, subject to the policies
and procedures in effect regarding participation in such benefits.

     7.  CONFIDENTIAL INFORMATION

     (a) During and after the Term of Employment, Executive will not, directly
or indirectly in one or a series of transactions, disclose to any person, or use
or otherwise exploit for the Executive's own benefit or for the benefit of
anyone other than the Companies, any Confidential Information, whether prepared
by Executive or not; PROVIDED, HOWEVER, that any Confidential Information may be
disclosed to officers, representatives, employees and agents of the Companies
who need to know such Confidential Information in order to perform the services
or conduct the operations required or expected of them in the Business (as
defined in SECTION 10). Executive shall use his best efforts to prevent the
removal of any Confidential Information from the premises of the Companies,
except as required in his normal course of employment by the Company. Executive
shall use commercially reasonable efforts to cause all persons or entities to
whom any Confidential Information shall be disclosed by him hereunder to observe
the terms and conditions set forth herein as though each such person or entity
was bound hereby. Executive shall have no obligation hereunder to keep
confidential any Confidential Information if and to the extent disclosure of any
thereof is specifically required by law; PROVIDED, HOWEVER, that in the event
disclosure is required by applicable law, the Executive shall provide the
Companies with prompt notice of such requirement, prior to making any
disclosure, so that the Companies may seek an appropriate protective order. At
the request of the Companies, Executive agrees to deliver to the Companies, at
any time during the Term of Employment, or thereafter, all Confidential
Information which he may possess or control. Executive agrees that all
Confidential Information of the Companies (whether now or hereafter existing)
conceived, discovered or made by him during the Term of Employment exclusively
belongs to the Companies (and not to Executive). Executive will promptly
disclose such Confidential Information to the Companies and perform all actions
reasonably requested by the Companies to establish and confirm such exclusive
ownership.

     (b) The terms of this SECTION 7 shall survive the termination of this
Agreement regardless of who terminates this Agreement, or the reasons therefor.

     8.  NON-INTERFERENCE

     (a) Executive acknowledges that the services to be provided give him the
opportunity to have special knowledge of the Companies and their Confidential
Information and the capabilities of individuals employed by or affiliated with
the Companies and that interference in these relationships would cause
irreparable injury to the Companies. In consideration of this Agreement,
Executive covenants and agrees that:

         (i)   During the Restricted Period (which shall not be reduced by any
     period of violation of this Agreement by Executive or period which is
     required for litigation to enforce the rights hereunder), Executive will
     not, without the express written approval of the Board of Directors of the
     Company, anywhere in the Market, directly or indirectly, in one or a series
     of transactions, own, manage, operate, control, invest or acquire an
     interest in, or otherwise engage or participate in, whether as a
     proprietor, partner, stockholder, lender, director, officer, employee,
     joint venturer, investor, lessor, supplier, customer, agent, representative
     or other participant, in any business which competes, directly or
     indirectly, with the Business in the Market ("COMPETITIVE BUSINESS")
     without regard to (A) whether the Competitive Business has its office,
     manufacturing or other business facilities within or without the Market,
     (B) whether any of the activities of the Executive referred to above occur
     or are performed within or without the Market or (C) whether the Executive
     resides, or reports to an office, within or without the Market; PROVIDED,
     HOWEVER, that (x) the Executive may, anywhere in the Market, directly or
     indirectly, in one or a series of transactions, own, invest or acquire an
     interest in up to five percent (5%) of the capital stock of a corporation
     whose capital stock is traded publicly, or that (y) Executive may accept
     employment with a successor company to the Company.

         (ii)  During the Restricted Period (which shall not be reduced by any
     period of violation of this Agreement by Executive or period which is
     required for litigation to enforce the rights hereunder), Executive will
     not without the express prior written approval of the Board of Directors of
     the Company (A) directly or indirectly, in one or a series of transactions,
     recruit, solicit or otherwise induce or influence any proprietor, partner,
     stockholder, lender, director, officer, employee, sales agent, joint
     venturer, investor, lessor, supplier, customer, agent, representative or
     any other person which has a business relationship with the Companies or
     had a business relationship with the Companies within the 24 month period
     preceding the date of the incident in question, to discontinue, reduce or
     modify such employment, agency or business relationship with the Companies,
     or (B) employ or seek to employ or cause any Competitive Business to employ
     or seek to employ any person or agent who is then (or was at any time
     within 24 months prior to the date the Executive or the Competitive
     Business employs or seeks to employ such person) employed or retained by
     the Companies. Notwithstanding the foregoing, nothing herein shall prevent
     the Executive from providing a letter of recommendation to an employee with
     respect to a future employment opportunity.

         (iii) The scope and term of this SECTION 8 would not preclude
     Executive from earning a living with an entity that is not a Competitive
     Business.

     (b) In the event that Executive breaches his obligations in any material
respect under SECTION 7, this SECTION 8 or SECTION 9, the Company, in addition
to pursuing all available remedies under this Agreement, at law or otherwise,
and without limiting its right to pursue the same shall cease all payments to
the Executive under this Agreement or any other agreement.

     (c) The terms of this SECTION 8 shall survive the termination of this
Agreement regardless of who terminates this Agreement, or the reasons therefor.

     9.  NON-DISPARAGEMENT. During and after the Term of Employment, the
Executive agrees that he shall not make any false, defamatory or disparaging
statements about the Companies or the officers or directors of the Companies.

     Whenever possible, each provision of this Agreement will be interpreted in
such manner as to be effective and valid under applicable law, but if any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such
invalidity, illegality or unenforceability will not affect any other provision
or any other jurisdiction, but this Agreement will be reformed, construed and
enforced in such jurisdiction as if such invalid, illegal or unenforceable
provision had never been contained herein. If any court determines that any
provision of SECTION 8 or any other provision hereof is unenforceable and
therefore acts to reduce the scope or duration of such provision, the provision
in its reduced form shall then be enforceable.

     16. WAIVER OF BREACH; SPECIFIC PERFORMANCE

     The waiver by the Company or Executive of a breach of any provision of this
Agreement by the other party shall not operate or be construed as a waiver of
any other breach of such other party. Each of the parties (and third party
beneficiaries) to this Agreement will be entitled to enforce its respective
rights under this Agreement and to exercise all other rights existing in its
favor. The parties hereto agree and acknowledge that money damages may not be an
adequate remedy for any breach of the provisions of SECTIONS 7, 8 and 9 of this
Agreement and that any party (and third party beneficiaries) may in its sole
discretion apply to any court of law or equity of competent jurisdiction for
specific performance and/or injunctive relief, including temporary restraining
orders, preliminary injunctions and permanent injunctions in order to enforce or
prevent any violations of the provisions of this Agreement. In the event either
party takes legal action to enforce any of the terms or provisions of this
Agreement, the nonprevailing party shall pay the successful party's costs and
expenses, including but not limited to, attorneys' fees, incurred in such
action.

     17. ASSIGNMENT; THIRD PARTIES

     Neither the Executive nor the Company may assign, transfer, pledge,
hypothecate, encumber or otherwise dispose of this Agreement or any of his or
its respective rights or obligations hereunder, without the prior written
consent of the other. The parties agree and acknowledge that each of the
Companies and the stockholders and investors therein are intended to be third
party beneficiaries of, and have rights and interests in respect of, Executive's
agreements set forth in SECTIONS 7, 8 and 9.

     18. AMENDMENT; ENTIRE AGREEMENT

     This Agreement may not be changed orally but only by an agreement in
writing agreed to by the party against whom enforcement of any waiver, change,
modification, extension or discharge is sought. This Agreement embodies the
entire agreement and understanding of the parties hereto in respect of the
subject matter of this Agreement, and supersedes and replaces all prior
agreements, understandings and commitments with respect to such subject matter,
including, without limitation, that certain Employment Agreement, dated August
7, 2000, between Executive and the Company.
