         ---------

                                    RECITALS
                                    --------

          The Company wishes to hire Executive as its Vice President,
Development Operations.  The parties hereto desire to set forth in writing the
terms of the Executive's employment relationship with the Company.

          In consideration of the mutual covenants contained herein and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

          1.  Employment.
              ----------

          (a) The Company hereby agrees to hire Executive to render full time
and exclusive services to the Company as its Vice President, Development
Operations, and to perform such other duties commensurate with such office as
Executive shall reasonably be directed by the senior management and/or Board of
Directors of the Company, for the period specified in Section 2.

          (b) Executive hereby accepts such employment and agrees to render the
services described above to the best of Executive's abilities in a diligent,
trustworthy, businesslike and efficient manner. Executive further agrees to
accept election and to serve during all or any part of the term of this
Agreement as an officer or director of the Company and of any subsidiary or
affiliate of the Company, without any compensation therefor, other than that
specified in this Agreement or as otherwise determined by the Board of Directors
of the Company or of any subsidiary or affiliate, as the case may be.

          (c) The duties to be performed by Executive hereunder shall be
performed primarily at the Company's offices in Boston, Massachusetts, subject
to reasonable travel requirements on behalf of the Company.

          2.  Term of Employment.
              ------------------

          The Employment Period of Executive by the Company shall commence on
the date hereof and end on July 4, 2001 (the "Initial Term") unless further
extended or sooner

                                       1

terminated as hereinafter provided. Executive may terminate his employment
during the Initial Term with six months written notice to the Company.
Commencing on July 5, 2001, and each July 5 thereafter, the term of Executive's
employment shall automatically be extended for one additional year to,
respectively, July 5, 2002, and each July 5 thereafter, unless, not later than
six months prior to the end of any renewal term, either party hereunder shall
have given notice to the other party that it does not wish to extend this
Agreement. If the Company gives Executive notice that it does not wish to extend
this Agreement during the Initial Term or any renewal term, Executive shall be
entitled to the severance payments provided in Section 4(d) hereof. As used
herein, the term "Employment Period" shall refer to the Initial Term and any
renewal term of Executive's employment with the Company.

          3.   Base Salary and Benefits.
               ------------------------

          (a)  During the Employment Period, Executive's base salary shall be
$200,000 per annum or such higher rate as the Company may designate from time to
time (the "Base Salary"), which salary shall be payable in regular installments
           -----------
in accordance with the Company's general payroll practices and shall be subject
to customary withholding.  In addition, during the Employment Period, Executive
shall be entitled to participate in all of the Company's employee benefit
programs for which senior executive employees of the Company and its
subsidiaries are generally eligible.

          (b)  The Company shall reimburse Executive for all reasonable expenses
incurred by Executive in the course of performing Executive's duties under this
Agreement which are consistent with the Company's policies in effect from time
to time with respect to travel, entertainment and other business expenses,
subject to the Company's requirements with respect to reporting and
documentation of such expenses.

          (c)  In addition to the Base Salary, Executive shall be eligible to
participate in the Company's bonus program, as such program may be established
and/or amended from time to time by the Board of Directors of the Company.

          (d)  Executive may be awarded, from time to time, additional
compensation (such as stock options, stock appreciation rights, performance
shares, restricted stock or unrestricted stock) pursuant to the Company's 1997
Stock Incentive Plan or any additional or replacement incentive compensation
program established for the key employees of the Company.  Any awards under such
programs shall be at such levels or in such amounts as the Board of Directors
deems, in its sole discretion, appropriate for the position occupied by
Executive and his performance therein.  Subject to Section 4 herein, the terms,
conditions and rights with respect to any such grants will be subject to the
actual provisions and conditions applicable to such plans.

          4.   Termination and Change of Control
               ---------------------------------

                                       2
<PAGE>

          (a) If the Executive shall die during the Employment Period, this
Agreement shall terminate, except that (i) Executive's surviving spouse or, if
none, his estate, shall be entitled to receive Executive's compensation
(including bonus) to the last day of the third calendar month following the date
of his death; and (ii) such termination shall not affect any rights which
Executive may have at the time of his death pursuant to any insurance or other
death benefit, retirement, stock option or other plans or arrangements of the
Company or of any subsidiary or affiliate of the Company, which rights shall
continue to be governed by the provisions of such plans and arrangements.

          (b) At the sole discretion of the Board of Directors, Executive may be
terminated if the Executive is disabled (as defined below) and shall have been
absent from his duties with the Company on a full time basis for one hundred and
eighty (180) consecutive days, and, within thirty (30) days after written notice
by the Company to do so, the Executive shall not have returned to the
performance of his duties hereunder on a full time basis.  In the event of such
termination, the Company shall make to Executive the payments specified in
Section 4(d).  As used herein, the term "disabled" shall (i) mean that Executive
                                         --------
is unable, as a result of a medically determinable physical or mental
impairment, to perform the duties and services of his position, or (ii) have the
meaning specified in any disability insurance policy maintained by the Company,
whichever is more favorable to the Executive.

          (c) The Company may, by notice to Executive, terminate Executive's
employment hereunder for cause.  As used herein, "cause" shall mean (i) the
                                                  -----
conviction of Executive of a felony or conviction of a misdemeanor if such
misdemeanor involves moral turpitude; or (ii) Executive's voluntary engagement
in conduct constituting larceny, embezzlement, conversion or any other act
involving the misappropriation of Company funds in the course of his employment;
or (iii) the willful refusal to carry out specific directions of the Board of
Directors, which directions shall be consistent with the provisions hereof; or
(iv) Executive's committing any act of gross negligence or intentional
misconduct in the performance or non-performance of his duties as an employee of
the Company; or (v) any material breach by the Executive of any material
provision of this Agreement (other than for reasons related only to the business
performance of the Company or business results achieved by Executive).  For
purposes of this Section 4(c), no act or failure to act on Executive's part
shall be considered to be reason for termination for cause if done, or omitted
to be done, by Executive in good faith and with the reasonable belief that the
action or omission was in the best interests of the Company.

          (d) Executive's employment may be terminated at any time by the
Company without cause; provided, however, that in such event Executive shall be
entitled to receive (so long as Executive executes and delivers the Company's
standard form of release) 100%of Executive's then effective annual Base Salary
for the remaining term of the then current Employment Period, plus one year.
The foregoing amounts shall be payable in one lump sum payment within five (5)
days after Executive's last day of active employment.  In addition, Executive
shall be entitled to continue participation in the Company's health and other
welfare

                                       3
<PAGE>

benefit plans for a period of up to one year or until Executive is covered by a
successor employer's benefit plans, whichever is sooner.

          (e) If (i) Executive's employment is terminated pursuant to
subsections (a), (b), (d), (e) or (g) of this Section 4, or (ii) a "Change in
Control" of the Company (as defined in Section 4(f) below) occurs; in either
case, all stock options, restricted stock, deferred compensation and similar
benefits which have not yet become vested on the date of termination or the date
of a Change in Control, as the case shall be, will become vested upon such
event, and Executive shall be permitted to exercise all such rights in
accordance with the administrative provisions of those plans, and in the case of
a Change of Control, whether or not Executive remains employed with the Company
or terminates his employment in accordance with this subsection (e). If a Change
in Control event involves a tender offer for all or part of the Company's
shares, the vesting date for stock options and restricted stock pursuant to this
subsection (e) shall be a date which permits Executive to participate in such
tender offer with such stock options or restricted shares. In addition, if a
Change in Control occurs, Executive may, after such Change in Control, terminate
his employment with the Company for any reason after the expiry of ninety (90)
days immediately following the effective date of such Change in Control, in
which event Executive shall be entitled to the payments specified in Section
4(d) above and to the other rights described elsewhere in this Agreement.

          (f) For purposes of this Agreement, a "Change in Control" of the
                                                 -----------------
Company shall be deemed to have occurred if: (i) any person (as such term is
used in Sections 13(d) and 14(d)(2) of the Securities and Exchange Act of 1934)
becomes the beneficial owner, directly or indirectly, of Company securities
representing 30% or more of the capital stock of the Company; or (ii)
individuals who constitute the Company's Board of Directors as of the date of
this Agreement (the "Incumbent Board") cease for any reason to
                     --------- -----
constitute at least a majority thereof, provided, however, that any person
becoming a director subsequent to the date of this Agreement whose election, or
nomination for election by the Company's stockholders, was approved by a vote of
at least 51% of the directors comprising the Incumbent Board (either by a
specific vote or by approval of the proxy statement of the Company in which such
person is named as a nominee for director, without objection to such nomination)
shall be, for the purpose of this clause (ii), considered as though such person
were a member of the Incumbent Board; or (iii) the Company's shareholders
approve a merger or consolidation (where in either case the Company is not the
survivor thereof) in which shareholders of the Company cease to own at least 80%
of the surviving entity's voting power, or a sale or disposition of all or
substantially all of the Company's assets or a plan of partial or complete
liquidation of the Company.

          (g) Executive's employment may be terminated by the Executive for Good
Reason. For purposes of this Agreement, "Good Reason" shall mean: (i) the
assignment to Executive of any duties inconsistent in any respect with
Executive's position (including status, offices, titles, and reporting
requirements), authority, duties or responsibilities as contemplated by Section
1(a) hereof, or any other action by the Company which results in a diminution in
such

                                       4
<PAGE>

position, authority, duties or responsibilities, excluding for this purpose an
isolated, insubstantial and inadvertent action not taken in bad faith and which
is remedied by the Company promptly after receipt of notice thereof given by
Executive; (ii) any failure by the Company to comply with any of the provisions
of Section 3 hereof, other than an isolated, insubstantial and inadvertent
failure not occurring in bad faith and which is remedied by the Company promptly
after receipt of notice thereof given by Executive; (iii) the Company's
requiring Executive to be based at any office or location other than as provided
in Section 1(c) hereof; (iv) any purported termination by the Company of
Executive's employment otherwise than as expressly permitted by this Agreement;
or (v) any failure by the Company to obtain an express assumption of this
Agreement by a successor as required pursuant to Section 14 hereof. For purposes
of this Section 4(g), any good faith determination of "Good Reason" made by
Executive shall be conclusive. Upon any termination pursuant to this subsection
(g), Executive shall be entitled to the payment specified in Section 4(d) hereof
and to the other rights described therein (subject to his compliance therewith).

          (h) Anything in this Agreement to the contrary notwithstanding, in the
event it shall be determined that any payment or distribution by the Company to
or for the benefit of Executive (whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise, but
determined without regard to any additional payments required under this
subsection (h) (a "Payment") would be subject to the excise tax imposed by
Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), or
any interest or penalties are incurred by Executive with respect to such excise
tax (such excise tax, together with any such interest and penalties are
hereinafter collectively referred to as the "Excise Tax"), the Company shall pay
to Executive at the time specified in subparagraph (k) below an additional
amount (a "Gross-Up Payment") such that the net amount retained by Executive,
after deduction of any Excise Tax on a Payment and any federal (and state and
local) income tax (and any interest and penalties imposed with respect thereto),
employment tax and Excise Tax on a Payment, shall be equal to the amount of all
the Payments.

          (i) For purposes of the foregoing subparagraph (h), the proper
amounts, if any, of the Excise Tax and the Gross-Up Payment shall be determined
in the first instance by the Company. Such determination by the Company shall be
communicated in writing by the Company to Executive at least fourteen (14) days
prior to the occurrence of a Change of Control. Within ten (10) days of being
provided with written notice of any such determination, Executive may provide
written notice to the Chairperson of the Compensation Committee of the Board of
Directors of the Company of any disagreement, in which event the amounts, if
any, of the Excise Tax and the Gross-Up Payment shall be determined by tax
counsel mutually selected by the Company and Executive. The determination of the
Company (or in the event of disagreement, the tax counsel selected) shall be
final and nonreviewable.

          (j) For purposes of determining whether any of the Payments will be
subject to the Excise Tax and the amount of such Excise Tax under subparagraph
(h), the following principles will be applicable:

                                       5
<PAGE>

          (A)       Any payments or benefits received or to be received by
                    Executive in connection with a termination of employment
                    shall be treated as "parachute payments" within the meaning
                    of Section 280G(b)(2) of the Code, and all "excess parachute
                    payments" within the meaning of Section 280G(b)(1) of the
                    Code shall be treated as subject to the Excise Tax unless in
                    the opinion of tax counsel mutually selected by the parties
                    pursuant to subsection (i) above, such other payments or
                    benefits (in whole or in part) do not constitute parachute
                    payments, or such excess parachute payments (in whole or in
                    part) represents reasonable compensation for services
                    actually rendered within the meaning of Section 280G(b)(4)
                    of the Code in excess of the base amount within the meaning
                    of Section 280G(b)(3) of the Code, or are otherwise subject
                    to the Excise Tax; and

          (B)       The value of any non-cash benefits or any deferred payment
                    or benefit shall be determined in accordance with Section
                    280G(d)(3) and (4) of the Code. For purposes of determining
                    the amount of the Gross-Up Payment, Executive shall be
                    deemed to pay federal income taxes at the highest marginal
                    rate of tax in the calendar year in which the Gross-Up
                    Payment is to be made and state and local income taxes at
                    the highest marginal rate of tax in the state and locality
                    of Executive's residence on the date of termination, net of
                    the maximum reduction in federal income taxes which could be
                    obtained from deduction of such state and local taxes.

          (k) The Payments provided for in subparagraph (h) shall be made in a
cash, lump-sum payment, net of any required tax withholdings, upon the later of
(i) the fifth business day following the effective date of termination, or (ii)
the calculation of the amount of the Gross-Up Payment under subparagraph (i).
Any Payment required hereunder that is not made in a timely manner shall bear
interest at a rate equal to one-hundred twenty percent (120%) of the monthly
compounded applicable federal rate, as in effect under Section 1274(d) of the
Code for the month in which Payment is otherwise required to be made.

          5.  Confidential Information.
              ------------------------

          (a) Executive acknowledges and agrees that the information,
observations and data obtained by him while employed by the Company and its
subsidiaries concerning the business or affairs of the Company or any other
subsidiary ("Confidential Information") are the property of the Company or such
             ------------------------
subsidiary. Therefore, Executive agrees to keep secret and retain in the
strictest confidence all Confidential Information, including without limitation,
trade "know-how" secrets, customer lists, pricing policies, operational methods,
technical processes, formulae, inventions and research projects and other
business affairs of the Company, learned by Executive prior to or after the date
of this Agreement, and not to disclose them to anyone outside the Company,
either during or after Executive's employment with the Company, except (i) in
the course of performing Executive's duties hereunder; (ii) with the Company's
express written

                                       6
<PAGE>

consent; (iii) to the extent that the Confidential Information becomes generally
known to and available for use by the public other than as a result of
Executive's acts or omissions; or (iv) where required to be disclosed by court
order, subpoena or other government process. If Executive shall be required to
make disclosure pursuant to the provisions of clause (iv) of the preceding
sentence, Executive promptly, but in no event more than 48 hours after learning
of such subpoena, court order or other governmental process, shall notify the
Company, by personal delivery or fax (pursuant to Section 9 hereof), and, at the
Company's expense, shall take all reasonably necessary steps requested by the
Company to defend against the enforcement of such subpoena, court order or other
governmental process and permit the Company to intervene and participate with
counsel of its own choice in any related proceeding.

          (b) Executive shall deliver to the Company at the termination of
Executive's employment, or at any other time the Company may request, all
memoranda, notes, plans, records, reports, computer tapes, printouts and
software and other documents and data (and copies thereof) relating to the
Confidential Information, Work Product (as defined below) or the business of the
Company or any subsidiary which Executive may then possess or have under his
control.

          6.  Inventions and Patents.  Executive acknowledges that all
              ----------------------
inventions, innovations, improvements, developments, methods, designs, analyses,
drawings, reports and all similar or related information (whether or not
patentable) which relate to the Company's or any of its subsidiaries' actual or
anticipated business, research and development or existing or future products or
services and which are conceived, developed or made by Executive while employed
by the Company or its predecessor and its subsidiaries ("Work Product") belong
                                                         ------------
to the Company or such subsidiary.  Executive shall promptly disclose such Work
Product to the Board and perform all actions reasonably requested by the Board
(whether during or after his employment) to establish and confirm such ownership
(including, without limitation, assignments, consents, powers of attorney and
other instruments).

          7.  Indemnification.  The Company will indemnify Executive and
              ---------------
Executive's legal representatives, to the fullest extent permitted by the laws
of the State of Delaware and the existing by-laws of the Company or any other
applicable laws or the provisions of any other corporate document of the
Company, and Executive shall be entitled to the protection of any insurance
policies the Company may elect to obtain generally for the benefit of its
directors and officers, against all costs, charges and expenses whatsoever
incurred or sustained by him or his legal representatives in connection with any
action, suit or proceeding to which Executive or Executive's legal
representatives may be made a party by reason of Executive being or having been
a director or officer of the Company or of any of its subsidiaries or affiliates
or actions taken purportedly on behalf of the Company or of any of its
subsidiaries or affiliates.

          8.  Executive's Representations.  Executive hereby represents and
              ---------------------------
warrants to the Company that (i) the execution, delivery and performance of this
Agreement by Executive

                                       7
<PAGE>

do not and shall not conflict with, breach, violate or cause a default under any
contract, agreement, instrument, order, judgment or decree to which Executive is
a party or by which he is bound, and (ii) upon the execution and delivery of
this Agreement by the Company, this Agreement shall be the valid and binding
obligation of Executive, enforceable in accordance with its terms. Executive
hereby acknowledges and represents that he has consulted with independent legal
counsel regarding his rights and obligations under this Agreement and that he
fully understands the terms and conditions contained herein.

          9.  Non-Compete, Non-Solicitation.
              -----------------------------

          (a) In further consideration of the compensation to be paid to
Executive hereunder, Executive acknowledges that during his employment with the
Company he will become familiar with the Company's trade secrets and with other
Confidential Information concerning the Company and its affiliates and that his
services shall be of special, unique and extraordinary value to the Company.
Therefore, Executive agrees that, during the Employment Period and for six
months thereafter (the "Noncompete Period"), he shall not, directly or
                        -----------------
indirectly, own any interest in, manage, control, participate in, consult with,
render services for, or in any manner engage in any business competing with the
businesses of the Company or its subsidiaries or affiliates, as such businesses
exist or are in process on the date of the termination of Executive's
employment.  Nothing herein shall prohibit Executive from being a passive owner
of not more than 2% of the outstanding stock of any class of a corporation which
is publicly traded, so long as Executive has no active participation in the
business of such corporation.

          (b) During the Noncompete Period, Executive shall not, directly or
indirectly, through another entity (i) induce or attempt to induce any employee
of the Company or any subsidiary or affiliate to leave the employ of the Company
or such subsidiary or affiliate, or in any way interfere with the relationship
between the Company or any subsidiary or affiliate and any employee thereof,
(ii) induce or attempt to induce any customer, supplier, licensee, licensor,
franchisee or other business relation of the Company or any subsidiary or
affiliate to cease doing business with the Company or such subsidiary or
affiliate, or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Company or any
subsidiary or affiliate (including, without limitation, making any negative
statements or communications about the Company or its subsidiaries or
affiliates).

          (c) If, at the time of enforcement of this Section, a court shall hold
that the duration, scope or area restrictions stated herein are unreasonable
under circumstances then existing, the parties agree that the maximum duration,
scope or area reasonable under such circumstances shall be substituted for the
stated duration, scope or area and that the court shall be allowed to revise the
restrictions contained herein to cover the maximum period, scope and area
permitted by law. Executive agrees that the restrictions contained in this
Section are reasonable.

                                       8
<PAGE>

          (d) In the event of the breach or a threatened breach by Executive of
any of the provisions of this Section, the Company, in addition and
supplementary to other rights and remedies existing in its favor, may apply to
any court of law or equity of competent jurisdiction for specific performance
and/or injunctive or other relief in order to enforce or prevent any violations
of the provisions hereof (without posting a bond or other security). In
addition, in the event of an alleged breach or violation by Executive of this
Section, the Noncompete Period shall be extended until such breach or violation
has been duly cured.

          11. Severability.  Whenever possible, each provision of this
              ------------
Agreement shall be interpreted in such manner as to be effective and valid under

illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

          12. Complete Agreement.  This Agreement constitutes the complete
              ------------------
agreement and understanding among the parties and supersedes and preempts any

inure to the benefit of and be enforceable by Executive, the Company and their

               -------------
construction, validity, enforcement and interpretation of this Agreement and the

law or conflict of law rules or provisions that would cause the application of
the laws of any jurisdiction other than the State of New York.

provisions of Section 5 as to which the parties shall have the right to apply
for specific performance to any court having equity jurisdiction; and (b) the
determination of Excise Tax and Gross-Up Payment pursuant to Section 4 herein;
shall be settled by arbitration in New York City by one arbitrator in accordance
with the Commercial Arbitration Rules of the American Arbitration Association
and judgement upon the award rendered by the arbitrator may be entered in any
court having jurisdiction thereof and any party to the arbitration may, if he
elects, institute proceedings in any court having jurisdiction for the specific
performance of any such award. The powers of the arbitrator shall include, but
not be limited to, the awarding of injunctive relief.

          19.  Legal Fees and Expenses.  The Company shall reimburse Executive

the payments to Executive required under this Agreement, and otherwise to
perform its obligations hereunder shall not be affected by any set-off,
counterclaim, recoupment, defense or other claim, right or action that the
Company may have against Executive.
