                           Employment Term;

                  (iii)    an amount equal to the value of Executive's vacation

                  (iv)     notwithstanding anything herein or in the governing
                           plan, stock or option agreement to the contrary, all
                           stock options and Restricted Stock shall continue to

                  (v)      an amount equal to any unpaid Second Deferred Sign-on
                           Bonus.

Restated Non-Competition and Proprietary Information Agreement attached as

hereafter effect a reorganization, consolidate with, or merge into any other
entity or transfer all or substantially all of its properties or assets to any
other person or entity. This Restated Agreement shall be binding upon and inure

waiver of any other or subsequent breach by such other party.

13. Severability. The parties agree that each provision contained in this
Restated Agreement shall be treated as a separate and independent clause, and
the unenforceability of any one clause shall in no way impair the enforceability

shall be entitled to seek injunctive relief and/or a decree for specific
performance, and such other relief as may be proper (including monetary damages
if appropriate).

20. Integration. This Restated Agreement, the Executive Non-Competition and
Proprietary Information Agreement attached as Exhibit A hereto, the Amended and
Restated Indemnification Agreement attached as Exhibit B hereto, and the
Employment Agreement, unless otherwise provided herein, form the entire
agreement between the parties hereto with respect to the subject matter

any agreement to keep in confidence proprietary information, knowledge or data
acquired by him.

23. Survival. Notwithstanding any provisions of this Restated Agreement to the
contrary, the obligations of Executive and the Company pursuant to Sections 7
through 24 hereof shall each survive termination of this Restated Agreement.

                            ARTICLE 1 - Stockholders

      1.1 Place of Meetings. All meetings of stockholders shall be held with in
the Commonwealth of Massachusetts unless the Articles of organization permit the
holding of stockholders' meetings outside Massachusetts, in which event such
meetings may be held either within or without Massachusetts. Meetings of
stockholders shall be held at the principal office of the corporation unless a
different place is fixed by the Board of Directors or the President and stated
in the notice of the meeting.

      1.2 Annual Meeting. The annual meeting of the stockholders shall be held
on the four Thursday in April in each year (or if that be a legal holiday in the
place where the meeting is to be held, on the next succeeding full business day)
at 10:00 A.M., unless a different date or hour is fixed by the Directors or the
President and stated in the notice of the meeting. The purposes for which the
annual meeting is to be held, in addition to those prescribed by law, by the
Articles of Organization or by these By-Laws, may be specified by the Board of
Directors or the President. If no annual meeting is held in accordance with the
foregoing provisions, a special meeting may be held in lieu of the annual
meeting, and any action taken at that special meeting shall have the same effect
as if it had been taken at the annual meeting, and in such case all references
in these By-Laws to the annual meeting of stockholders shall be deemed to refer
to such special meeting.

      1.3 Special Meetings. Special meetings of stockholders may be called by
the President or by the Board of Directors. In addition, upon written
application of one or more stockholders who are entitled to vote and who hold at
least the Required Percentage (as defined below) of the, capital stock entitled
to vote at the meeting, special meetings shall be called by the Clerk, or in the
case of the death, absence, incapacity or refusal of the Clerk, by any other
officer.

      For purposes of this Section 1.3, the "Required Percentage" shall be (i)
10% at any time at which the corporation shall not have a class of voting stock
registered under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and (ii) 80% or such lesser percentage as shall constitute the maximum
percentage permitted by law for this purpose at any time the corporation has a
class of voting stock registered under the Exchange Act.

      1.4 Notice of Meetings. A written notice of each meeting of stockholders,
stating the place, date and hour thereof, and the purposes for which the meeting
is to be held, shall be given by the Clerk, Assistant Clerk or other person
calling the meeting at least seven days before the meeting to each stockholder
entitled to vote at the meeting and to each stockholder who by law, by the
Articles of organization or by these By-Laws is entitled to such notice, by
leaving such notice with him or at his residence or usual place of business, or
by mailing it postage prepaid and addressed to him at his address as it appears
in the records of the corporation. Whenever any

                                      -1-
<PAGE>

notice is required to be given to a stockholder by law, by the Articles of
Organization or by these By-Laws, no such notice need be given if a written
waiver of notice, executed before or after the meeting by the stockholder or his
authorized attorney, is filed with the records of the meeting.

      1.5 Quorum.

            (a) Except as otherwise provided by law, or in the Articles of
Organization, these Bylaws or, to the extent authorized by law, a resolution of
the Board of Directors requiring satisfaction of a greater quorum requirement
for any voting group, a majority of the votes entitled to be cast on the matter
by a voting group constitutes a quorum of that voting group for action on that
matter. As used in these Bylaws, a voting group includes all shares of one or
more classes or series that, under the Articles of Organization or the
Massachusetts Business Corporation Act, as in effect from time to time (the
"MBCA"), are entitled to vote and to be counted together collectively on a
matter at a meeting of shareholders.

            (b) A share once represented for any purpose at a meeting is deemed
present for quorum purposes for the remainder of the meeting and for any
adjournment of that meeting unless (1) the shareholder attends solely to object
to lack of notice, defective notice or the conduct of the meeting on other
grounds and does not vote the shares or otherwise consent that they are to be
deemed present, or (2) in the case of an adjournment, a new record date is or
shall be set for that adjourned meeting.

      1.6 Adjournments. Any meeting of stockholders may be adjourned to any
other time and to any other place at which a meeting of stockholders may be held
under these By-Laws by the stockholders present or represented at the meeting,
although less than a quorum, or by any officer entitled to preside or to act as
clerk of such meeting, if no stockholder is present. It shall not be necessary
to notify any stockholder of any adjournment. Any business which could have been
transacted at any meeting of the stockholders as originally called may be
transacted at any adjournment of the meeting.

      1.7 Voting and Proxies.

            (a) Except as otherwise provided in this Section 1.7 (a) or the
Articles of Organization, each outstanding share, regardless of class, is
entitled to one vote on each matter voted on at a shareholders' meeting. Only
shares are entitled to vote, and each fractional share, if any, is entitled to a
proportional vote. Absent special circumstances, the shares of the Corporation
are not entitled to vote if they are owned, directly or indirectly, by another
entity of which the Corporation owns, directly or indirectly, a majority of the
voting interests; provided, however, that nothing in these Bylaws shall limit
the power of the Corporation to vote any shares held by it, directly or
indirectly, in a fiduciary capacity. Unless the Articles of Organization provide
otherwise, redeemable shares are not entitled to vote after notice of redemption
is given to the holders and a sum sufficient to redeem the shares has been
deposited with a bank, trust company or other financial institution under an
irrevocable obligation to pay the holders the redemption price upon surrender of
the shares.

            (b) A shareholder may vote his or her shares in person or may
appoint a proxy to vote or otherwise act for him or her by signing an
appointment form, either personally or by

                                      -2-
<PAGE>

his or her attorney-in-fact. An appointment of a proxy is effective when
received by the Secretary or other officer or agent authorized to tabulate
votes. Unless otherwise provided in the appointment form, an appointment is
valid for a period of 11 months from the date the shareholder signed the form
or, if it is undated, from the date of its receipt by the officer or agent. An
appointment of a proxy is revocable by the shareholder unless the appointment
form conspicuously states that it is irrevocable and the appointment is coupled
with an interest, as defined in the MBCA. An appointment made irrevocable is
revoked when the interest with which it is coupled is extinguished. The death or
incapacity of the shareholder appointing a proxy shall not affect the right of
the Corporation to accept the proxy's authority unless notice of the death or
incapacity is received by the Secretary or other officer or agent authorized to
tabulate votes before the proxy exercises his or her authority under the
appointment. A transferee for value of shares subject to an irrevocable
appointment may revoke the appointment if he or she did not know of its
existence when he or she acquired the shares and the existence of the
irrevocable appointment was not noted conspicuously on the certificate
representing the shares or on the information statement for shares without
certificates. Subject to the provisions of Section 7.24 of the MBCA, or any
successor Section thereto, and to any express limitation on the proxy's
authority appearing on the face of the appointment form, the Corporation is
entitled to accept the proxy's vote or other action as that of the shareholder
making the appointment.

      1.8 Action at Meeting. If a quorum of a voting group exists, favorable
action on a matter, other than the election of Directors, is taken by a voting
group if the votes cast within the group favoring the action exceed the votes
cast opposing the action, unless a greater number of affirmative votes is
required by law, the Articles of Organization, these Bylaws or, to the extent
authorized by law, a resolution of the Board of Directors requiring receipt of a
greater affirmative vote of the shareholders, including more separate voting
groups. Directors are elected by a plurality of the votes cast by the shares
entitled to vote in the election at a meeting at which a quorum is present. No
ballot shall be required for such election unless requested by a shareholder
present or represented at the meeting and entitled to vote in the election.

      1.9 Action without Meeting. Any action required or permitted to be taken
at any meeting of the stockholders may be taken without a meeting if all
stockholders entitled to vote on the matter consent to the action in writing and
the written consents are filed with the records of the meetings of stockholders.
Each such consent shall be treated for all purposes as a vote at a meeting.

                              ARTICLE 2 - Directors

      2.1 Powers. The business of the corporation shall be managed by a Board of
Directors, who may exercise all the powers of the corporation except as
otherwise provided by law, by the Articles of Organization or by these By-Laws.
In the event of a vacancy in the Board of Directors, the remaining Directors,
except as otherwise provided by law, may exercise the powers of the full Board
until the vacancy is filled.

      2.2 Number, Election and Qualification. The number of Directors which

Director, officer or Plan Fiduciary (as defined below) of the corporation or who
is serving, or shall have served, at the request of the corporation as a
Director or officer of another organization in which the corporation owns any
shares or of which it is a creditor, against all liabilities and expenses
(including judgments, fines, penalties and reasonable attorneys' fees and all
amounts paid, other than to the corporation or such other organization, in
compromise or settlement) imposed upon or incurred by any such person in
connection with, or arising out of, the defense or disposition of any action,
suit or other proceeding, whether civil or criminal, in which he may be a
defendant or with which he may be threatened or otherwise involved, directly or
indirectly, by reason of his being or having been such a Director, officer or
Plan Fiduciary.

                                      -10-
<PAGE>

      The corporation shall provide no indemnification with respect to any
matter as to which any such Director, officer or Plan Fiduciary shall be finally
adjudicated in such action, suit or proceeding not to have acted in good faith
in the reasonable belief that his action was in the best interests of the
corporation. The corporation shall provide no indemnification with respect to
any matter settled or compromised, pursuant to a consent decree or otherwise,
unless such settlement or compromise shall have been approved as in the best
interests of the corporation, after notice that indemnification is involved, by
(i) a disinterested majority of the Board of Directors or, (ii) the holders of a
majority of the outstanding stock entitled to elect Directors, voting as a
single class, exclusive of any stock owned by any interested Director, officer
or Plan Fiduciary.

      Indemnification may include payment by the corporation of expenses in
defending a civil or criminal action or proceeding in advance of the final
disposition of such action or proceeding upon receipt of an undertaking by the
person indemnified to repay such payment if it is ultimately determined that
such person is not entitled to indemnification under this Article.

      As used in this Article, the terms "Director", "officer" and "Plan
Fiduciary" include their respective heirs, executors, administrators and legal
representatives, and an "interested" Director, officer or Plan Fiduciary is one
against whom in such capacity the proceeding in question or another proceeding
on the same or similar grounds is then pending.

      To assure indemnification under this Article of all persons who are
determined by the corporation or otherwise to be or to have been "fiduciaries"
of any employee benefit plan of the corporation which may exist from time to
time, this Article shall be interpreted as follows: (i) "Plan Fiduciary" shall
mean any Director, officer or employee of the corporation who serves such an
employee benefit plan in a fiduciary capacity at the request of the corporation;
(ii) "fines" shall be deemed to include any excise taxes assessed on a person
with respect to an employee benefit plan pursuant to the Employee Retirement
Income Security Act of 1974; and (iii) actions taken or omitted by a person with
respect to an employee benefit plan in the performance of such person's duties
for a purpose reasonably believed by such person to be in the interest of the
participants and beneficiaries of the plan shall be deemed to be for a purpose
which is in the best interests of the corporation.

      The right of indemnification provided in this Article shall not be
exclusive of or affect any other rights to which any Director, officer or Plan
Fiduciary may be entitled under any agreement, statute, vote of stockholders or
otherwise. The corporation's obligation to provide indemnification under this
Article shall be offset to the extent of any other source of indemnification or
any otherwise applicable insurance coverage under a Policy maintained by the
corporation or any other person. Nothing contained in this Article shall affect
any rights to which corporate personnel other than Directors and officers may be
entitled by contract or otherwise.

be kept in Massachusetts at the principal office of the corporation, or at an
office of its transfer agent or of the Clerk. These copies and records need not
all be kept in the same office. They shall be available at all reasonable times
