                             ARTICLE VI (CONTINUED)
                                      RIDER

                      PLACE OF MEETINGS OF THE STOCKHOLDERS

     Meetings of the stockholders may be held anywhere in the United States as
shall be determined from time to time by the directors or as shall be stated in
the notice of the meeting.

                                     BYLAWS

     The directors may make, amend or repeal the bylaws, in whole or in part,
except with respect to any provision thereof which by law requires action by the
stockholders.

                                   PARTNERSHIP

     The corporation shall have the power to act as a partner in any business
enterprise which the corporation would have the power to conduct by itself.

                         INTERESTED PARTY TRANSACTIONS

     The corporation may enter into contracts and otherwise transact business as
vendor, purchaser or otherwise with its directors, officers and stockholders and
with corporations, joint stock companies, trusts, firms and associations in
which they are or may be or become interested as directors, officers,
stockholders, members, trustees, beneficiaries or otherwise as freely as though
such adverse interest did not exist even though the vote, action or presence of
such director, officer or stockholder may be necessary to obligate the
corporation upon such contract or transaction; and no such contract or
transaction shall be avoided and no such director, officer or stockholder shall
be held liable to account to the corporation or to any creditor or stockholder
of the corporation for any profit or benefit realized by him through any such
contract or transaction by reason of such adverse interest nor by reason of any
fiduciary relationship of such director, officer or stockholder to the
corporation arising out of such office or stock ownership; provided (in the case
of directors and officers but not in the case of any stockholder who is not a
director or officer of the corporation) the nature of the interest of such
director or officer, though not necessarily the details or extent thereof, be
known by or disclosed to the directors. Ownership or beneficial interest in a
minority of the stock or securities of another corporation, joint stock company,
trust, firm or association shall not be deemed to constitute an interest adverse
to this corporation in such other corporation, joint stock company, trust, firm
or association and need not be disclosed. A general notice that a director or
officer of the corporation is interested in any corporation, joint stock
company, trust, firm or association shall be sufficient disclosure as to such
director or officer with respect to all contracts and transactions with that
corporation, joint stock company, trust, firm or association. In any event, the
authorizing or ratifying vote of a majority of the capital stock of the
corporation outstanding and

<Page>

entitled to vote passed at a meeting duly called and held for the purpose shall
validate any such contract or transaction as against all stockholders of the
corporation, whether of record or not at the time of such vote, and as against
all creditors of, and other claimants under, the corporation, and no contract or
transaction shall be avoided by reason of any provision of this paragraph which
would be valid but for these provisions.

            LIABILITY OF DIRECTORS TO THE CORPORATION OR STOCKHOLDERS

     No director shall be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director
notwithstanding any provision of law imposing such liability; provided, however,
that, to the extent required by applicable law, this provision shall not
eliminate the liability of a director (i) for any breach of the director's duty
of loyalty to the corporation or its stockholders, (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) under Section 61 or 62 or successor provisions of the
Massachusetts Business Corporation Law, or (iv) for any transaction from which
the director derived an improper personal benefit. No amendment to or repeal of
this provision shall apply to or have any effect on the liability or alleged
liability of any director for or with respect to any acts or omissions of such
director occurring prior to such amendment or repeal.

                INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS

     The corporation shall indemnify, to the full extent permitted by
Massachusetts law, each person who is or was a director, officer, employee or
other agent of the corporation, each person who is or was serving at the request
of the corporation as a director, trustee, officer, employee or other agent of
another organization in which it directly or indirectly owns shares or of which
it is directly or indirectly a creditor and each person who is or was serving at
the request of the corporation in any capacity with respect to any employee
benefit plan, against all liabilities, costs and expenses, including, without
limitation, amounts paid in satisfaction of judgments, in settlement or as fines
and penalties, and counsel fees and disbursements reasonably incurred by him in
connection with the defense or disposition of or otherwise in connection with or
resulting from any action, suit or other proceeding, whether civil, criminal,
administrative or investigative, before any court or administrative or
legislative or investigative body, in which he may be or may have been involved
as a party or otherwise or with which he may be or may have been threatened,
while in office or thereafter by reason of his being or having been such a
director, officer, employee, agent or trustee, or having served in any capacity
with respect to any employee benefit plan, or by reason of any action taken or
not taken in any such capacity, except with respect to any matter as to which he
shall have been finally adjudicated by a court of competent jurisdiction not to
have acted in good faith in the reasonable belief that his action was in the
best interests of the corporation or, to the extent that such matter relates to
service with respect to any employee benefit plan, in the best interest of the
participants or beneficiaries of such employee benefit plan. Expenses,
including, without limitation, counsel fees and disbursements, so incurred by
any such person in defending any such action, suit or proceeding may be paid
from time to time by the corporation in advance of the final disposition of
such action, suit or proceeding upon receipt of an undertaking by or on behalf
of the person

<Page>

indemnified to repay the amounts so paid if it shall ultimately be determined
that indemnification of such expenses is not authorized hereunder, which
undertaking may be accepted without reference to the financial ability of such
person to make repayment.

     As to any matter disposed of by settlement by any such person, pursuant to
a consent decree or otherwise, no such indemnification either for the amount of
such settlement or for any other expenses shall be provided unless such
settlement shall be approved as in the best interests of the corporation, after
notice that it involves such indemnification (i) by a vote of a majority of the
disinterested directors then in office (even though the disinterested directors
be less than a quorum), or (ii) by any disinterested person or persons to whom
the question may be referred by vote or a majority of such disinterested
directors, voting as a single class, exclusive of any stock owned by any
interested persons, or (iii) by any disinterested person or persons to whom the
question may be referred by vote of the holders of a majority of such stock. No
such approval shall prevent the recovery from any such officer, director,
employee, agent or trustee or any such person serving in any capacity with
respect to any employee benefit plan or any amounts paid to him on his behalf as
indemnification in accordance with the preceding sentence if such person is
subsequently adjudicated by a court of competent jurisdiction not to have acted
in good faith in the reasonable belief that this action was in the best
interests of the corporation or, to the extent that such matter relates to
service with respect to an employee benefit plan, in the best interests of the
participants or beneficiaries of such employee benefit plan.

     The right of indemnification hereby provided shall not be exclusive of or
affect any other rights to which any director, officer, employee, agent or
trustee or any such person serving in any capacity with respect to any employee
benefit plan may be entitled or which may lawfully be granted to him. As used
herein, the terms "director," "officer," "employee," "agent" and "trustee"
include their respective executors, administrators and other legal
representatives, an "interested" person is one against whom the action, suit or
other proceeding in question or another action, suit or other proceeding on the
same or similar grounds is then or had been pending or threatened, and a
"disinterested" person is a person against whom no such action, suit or other
proceeding is then or had been pending or threatened.

     By action of the board of directors, notwithstanding any interest of the
directors in such action, the corporation may purchase and maintain insurance,
in such amounts as the board of directors may from time to time deem
appropriate, on behalf of any person who is or was a director, officer, employee
or other agent of the corporation, or is or was serving at the request of the
corporation as a director, trustee, officer, employee or other agent of another
organization or with respect to any employee benefit plan, in which it directly
or indirectly owns shares or of which it is directly or indirectly a creditor,
against any liability incurred by him in any such capacity, or arising out of
his status as such, whether or not the corporation would have the power to
indemnify him against such liability.
