                             Other Lawful Provisions
                             -----------------------

      6. The following additional provisions are hereby established for the
management, conduct and regulation of the business and affairs of the
Corporation, and for creating, limiting, defining, and regulating the powers of
the Corporation and of its Directors and stockholders:

            (a) The Board of Directors is authorized and empowered from time to
time in its discretion to make, amend or repeal the By-laws in part or in whole,
except with respect to any provision thereof which by law or the By-laws
requires action by the stockholders.

            (b) The Board of Directors shall have full power and authority to
determine the terms and manner of issue, including but not limited to the
consideration therefor, and to issue or cause the issue of all shares of capital
stock of the Corporation now or from time to time hereafter authorized.

            (c) Meetings of the stockholders may be held outside The
Commonwealth of Massachusetts at such location within the United States as the
Board of Directors may determine. The books of the Corporation may be kept
(subject to any provision contained in the statutes) at such place or places
within The Commonwealth of Massachusetts as may be designated from time to time
by the Board of Directors or in the By-Laws of the Corporation. Elections of
Directors need not be by ballot unless the By-Laws of the Corporation shall so
provide.

            (d) Any contract, transaction or act of the Board of Directors
purporting to be in behalf of the Corporation which shall be authorized,
approved or ratified by the holders of a majority of the outstanding shares of
the Corporation's stock at any special meeting duly called for that purpose, or
at any annual meeting at which a quorum is present or represented, or by their
consent in writing, shall be valid and binding as though authorized, approved
and ratified by every shareholder of the Corporation.

            (e) No director of the Corporation shall be liable to the
Corporation or its stockholders for monetary damages for breach of judiciary
duty as a director notwithstanding any provision of law imposing such liability;
provided, however, this provision shall not eliminate or limit 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 sixty-one or sixty-two of Chapter 156B of the General Laws, or (iv) for
any transaction from which the director derived an improper personal benefit.

                  Each person who shall be, or shall have been, a director or
officer of the Corporation, or who shall serve, or shall have served, at its
request as a director or officer of another corporation, or as trustee or
officer of an association or trust in which the Corporation owns stock or
shares, or of which the Corporation is a creditor, shall be





                             CONTINUATION SHEET VI B
                             -----------------------

indemnified by the Corporation against all liabilities and expenses at any time
imposed upon or reasonably incurred by him in connection with, arising out of or
resulting from any action, suit or proceeding in which he may be involved or
with which he may be threatened, by reason of his then serving or theretofore
having served as such director, trustee or officer, or by reason of any alleged
act or omission by him in any such capacity (including, without limitation, the
making of loans to shareholders, if and to the extent performed in conformity
with the provisions of these Articles), whether or not he shall be serving as
such director, trustee or officer at the time any or all of such liabilities or
expenses shall be imposed upon or incurred by him. The matters covered by the
foregoing indemnity shall include any amounts paid by any such person in
compromise or settlement, if such compromise or settlement shall be approved as
in the best interests of the Corporation by resolution of a disinterested
majority of the Board of Directors, or by vote of disinterested stockholders,
holding a majority of the shares of stock entitled to vote, present or
represented at a meeting called for the purpose; but such matters shall not
include liabilities or expenses imposed or incurred in connection with any
matters as to which such person shall be finally adjudged 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 matters covered by the
foregoing indemnity shall also include payment by the Corporation of expenses
incurred in defending a civil or criminal action or proceeding in advance of
final disposition of such action or proceeding, provided, that the Corporation
shall have received an undertaking by the person indemnified to repay such
payment if he shall be adjudicated to be not entitled to indemnification under
Section 67 of Chapter 156B of the General Laws.

                  Each person who shall be or become a director, trustee or
officer as aforesaid shall be deemed to have accepted and to have continued to
serve in such office in reliance upon the indemnity herein provided. These
indemnity provisions shall be separable, and if any portion hereof shall be
finally adjudged to be invalid, such invalidity shall not affect any other
portion which can be given effect. These indemnity provisions shall not be
exclusive of any other right which any director, trustee or officer may have or
hereafter acquire, whether under any by-law, vote of stockholders, agreement,
judgment, decree, provision of law, or otherwise, and these indemnity provisions
and all other such rights shall be cumulative.

            (f) No contract or other transaction between the Corporation and any
other person, firm or corporation shall, in the absence of fraud, in any way be
affected or invalidated, nor shall any officer or director be subject to
surcharge with respect to any such contract or transaction, by the fact that
such officer or director, or any firm of which any officer or director is a
shareholder, officer or director, is a party to, or may be pecuniarily or
otherwise interested in, such contract or transaction, provided, that the fact
that the individual or such firm or corporation is so interested shall be known
to the Board of Directors prior to or shall be disclosed to the Board of
Directors at the meeting at which, or



                             CONTINUATION SHEET VI C
                             -----------------------


prior to the directors' executing their written consents by which, action to
authorize, ratify, or approve such contract or transaction shall be taken. Any
director of the Corporation may vote upon or give his written consent to any
contract or other transaction between the Corporation and any subsidiary or
affiliated corporation without regard to the fact that he is also a director or
officer of such subsidiary or affiliated corporation.

            (g) Each director and officer of the Corporation shall, in the
performance of his duties, be fully protected in relying in good faith upon the
books of account of the Corporation, reports made to the Corporation by any of
its officers or employees or by counsel, accountants, appraisers or other
experts or consultants selected with reasonable care by the directors or
officers of the Corporation, or upon other records of the Corporation.

            (h) Except as may be otherwise provided herein, the Corporation
reserves the right to amend, alter, change or repeal any provision contained in
these Articles of Organization, in the manner now or hereafter prescribed by
statute, and all rights conferred upon stockholders herein are granted subject
to this reservation.

            (i) No stockholder shall have any right to examine any property or
any books, accounts or other writings of the Corporation if there is reasonable
ground for belief that such examination will for any reason be adverse to the
interests of the Corporation, and a vote of the directors refusing permission to
make such examination and setting forth that in the opinion of the directors
such examination would be adverse to the interest of the Corporation shall be
prima facie evidence that such examination would be adverse to the interests of
the Corporation. Every such examination shall be subject to such reasonable
regulations as the directors may establish in regard thereto.

            (j) The directors may specify the manner in which the accounts of
the Corporation shall be kept and may determine what constitutes net earnings,
profits and surplus, what amounts, if any, shall be reserved for any corporate
purpose, and what amounts, if any shall be declared as dividends. Unless the
Board of Directors otherwise specifies, the excess of the consideration received
for any share of capital stock over its par value shall be paid-in surplus. All
surplus shall be available for any corporate purpose, including the payment of
dividends.

            (k) The purchase or other acquisition or retention by the
Corporation of shares of its own capital stock shall not be deemed a reduction
of its capital. Upon any reduction of capital or capital stock, no stockholder
shall have any right to demand any distribution from the Corporation, except as
and to the extent that the stockholders shall so have provided at the time
authorizing such reduction.

            (l) The Corporation shall have the power to be a partner in any
business enterprise which it would have power to conduct itself.
