     Section 2.3. Special Meetings. Special meetings of stockholders may be
called by the President or by the Board of Directors, and shall be called by
the Clerk or, in case of death, absence, incapacity or refusal of the Clerk, by
any other officer, upon written application of one or more stockholders who hold
at least one tenth part in interest of the capital stock entitled to vote at the
meeting. At any special meeting only business to which a reference shall have
been contained in the notice of such meeting may be transacted.

     Section 2.4. Notice of Meetings. Written or printed notice of each meeting
of stockholders, stating the place, date and hour and the purposes of the
meeting shall be given by the Clerk or other officer calling the meeting at
least seven days, but not more than sixty days, before the meeting to each
stockholder entitled to vote at the meeting or entitled to such notice by
leaving such notice with him at his residence or usual place of business or by
mailing it, postage prepaid, and addressed to the stockholder at his address as
it appears in the records of the corporation. No notice need be given to any
stockholder if he, or his authorized attorney, waives such notice by a writing
executed before or after the meeting and filed with the records of the meeting
or by his presence, in person or by proxy, at the meeting. Any person authorized
to give notice of any such meeting may make affidavit of such notice, which, as
to the facts therein stated, shall be conclusive. It shall be the duty of every
stockholder to furnish to the Clerk of the corporation or to the transfer agent,
if any, of the class of stock owned by him, his current post office address.

majority in interest of all capital stock entitled to vote at such meeting or,
if two or more classes of stock are issued, outstanding and entitled to vote as
separate classes, a majority in interest of each class, present in person or
represented by proxy, shall constitute a quorum. The announcement of a quorum by
the officer presiding at the meeting shall constitute a conclusive determination
that a quorum is present. The absence of such an announcement shall have no
significance. Shares of its own stock held by the corporation or held for its
use and benefit shall not be counted in determining the total number of shares
outstanding at any particular time. If a quorum is not present or represented,
the stockholders present or represented and entitled to vote at such meeting, by
a majority vote, may adjourn the meeting from time to time, without notice other
than announcement at the meeting until a quorum is present or represented. At
any adjourned meeting at which a quorum shall be present or represented,


   8


                                       -3-

any business may be transacted which might have been transacted if the meeting
had been held as originally called. The stockholders present at a duly organized
meeting may continue to transact business until adjournment notwithstanding the
withdrawal of one or more stockholders so as to leave less than a quorum.

     Section 2.6. Voting. Except as otherwise provided by law or the Articles of
Organization, at all meetings of stockholders each stockholder shall have one
vote for each share of stock entitled to vote and registered in his name and a
proportionate vote for a fractional share. Any stockholder may vote in person or
by proxy dated not more than six months prior to the meeting and filed with the
Clerk of the meeting. Every proxy shall be in writing, subscribed by a
stockholder or his authorized attorney-in-fact, and dated. A proxy with respect
to stock held in the name of two or more persons shall be valid if executed by
any one of them unless at or prior to exercise of the proxy the corporation
receives a specific written notice to the contrary from any one of them. No
proxy shall be valid after the final adjournment of the meeting. Voting on all
matters, including the election of directors, shall be by voice vote unless
voting by ballot is requested by any stockholder. Except as otherwise provided
by law, the Articles of Organization, or these By-laws, at all meetings of
stockholders all questions shall be determined by a vote of a majority of the
shares voting, or, if two or more classes of stock are entitled to vote as
separate classes, a vote of a majority of the shares voting of each class
voting, present in person or represented by proxy. The corporation shall not,
directly or indirectly, vote shares of its own stock.

     Section 2.7. Inspectors of Election. Two inspectors may be appointed by
the Board of Directors before or at each meeting of stockholders, or, if no
such appointment shall have been made, the presiding officer may make such
appointment at the meeting. At the meeting for which they are appointed, such
inspectors shall open and close the polls, receive and take charge of the
proxies and ballots, and decide all questions touching on the qualifications of
voters, the validity of proxies and the acceptance and rejection of votes. If
any inspector previously appointed shall fail to attend or refuse or be unable
to serve, the presiding officer shall appoint an inspector in his place.

     Section 2.8. Action Without Meeting. Any action which may be taken by
stockholders may be taken without a meeting if all stockholders entitled to vote

filed with the records of the meetings of stockholders. Such

consents shall be treated for all purposes as a vote at a meeting.

shall be given to each director by the President, Clerk or other officer calling
the meeting at least two days prior to such meeting if given in person by
telephone or by telegram or at least four days prior to such meeting if given by
mail. Notice shall be deemed to have been duly given, if by mail, by depositing

the requisite fee at any telegraph office, the letter or telegram being
addressed to the director at his last known mailing address as it appears on the

such notice by a writing executed before or after the meeting and filed with the
records of the meeting or by his attendance at the meeting without protesting at

of adjourned meetings of the Board of Directors need be given.

     Section 3.8. Quorum. At all meetings of the Board of Directors, a majority
of the directors then in office shall constitute a quorum. If a quorum is not

Unless otherwise specified in the resignation, its acceptance shall not be

                                Article V - Stock

     Section 5.1. Stock Certificates. Each stockholder shall be entitled to a
certificate or certificates of stock of the corporation in such form as the
Board of Directors may from time to time prescribe. Each certificate shall be
duly numbered and entered in the books of the corporation as it is issued, shall
state the holder's name and the number and the class and the designation of the
series, if any, of his shares, shall be signed by the President or a Vice
President and by the Treasurer or an Assistant Treasurer and may, but need not,
be sealed with the seal of the corporation. If any stock certificate is signed
by a transfer agent, or by a registrar, other than a director, officer or
employee of the corporation, the signatures thereon of the officers may be
facsimiles. In case any officer who has signed or whose facsimile signature has
been placed on any certificate shall have ceased to be such officer before such
certificate is issued, it may nevertheless be issued by the corporation and
delivered with the same effect as if he were such officer at the time of its
issue. Every certificate of stock which is subject to any restriction on
transfer pursuant to the Articles of Organization, the By-laws or any agreement
to which the


   15


                                      -10-

corporation is a party, shall have the restrictions noted conspicuously on the
certificate and shall also set forth on the face or back of the certificate
either (i) the full text of the restriction, or (ii) a statement of the
existence of such restriction and a statement that the corporation will furnish
a copy thereof to the holder of such certificate upon written request and
without charge. Every certificate issued at a time when the corporation is
authorized to issue more than one class or series of stock shall set forth upon
the face or back of the certificate either (i) the full text of the preferences,
voting powers, qualifications and special and relative rights of the shares of
each class and series, if any, authorized to be issued, as set forth in the
Articles of Organization or (ii) a statement of the existence of such
preferences, powers, qualifications and rights, and a statement that the
corporation will furnish a copy thereof to the holder of such certificate upon
written request and without charge.

     Section 5.2. Transfer of Stock. Subject to any transfer restrictions then
in force, the shares of stock of the corporation shall be transferable only upon
its books by the holders thereof in person or by their duly authorized attorneys
or legal representatives. Such transfer shall be effected by delivery of the old
certificate, together with a duly executed assignment and power to transfer
endorsed thereon or attached thereto and with such proof of the authenticity of
the signature and such proof of authority to make the transfer as the
corporation or its agents may reasonably require, to the person in charge of the
stock and transfer books and ledgers or to such other person as the Board of
Directors may designate, who shall thereupon cancel the old certificate and
issue a new certificate. The corporation may treat the holder of record of any
share or shares of stock as the owner of such stock, and shall not be bound to
recognize any equitable or other claim to or interest in such share on the part
of any other person, whether or not it shall have notice thereof, express or
otherwise.

     Section 5.3 Fixing Date for Determination of Stockholders' Rights. The 
Board of Directors may fix in advance a time, not exceeding sixty days preceding
the date of any meeting of stockholders, or the date for the payment of any
dividend or the making of any distribution to stockholders, or the date for the
allotment of rights, or the date when any change or conversion or exchange of
capital stock shall go into effect, or the last date on which the consent or
dissent of stockholders may be effectively expressed for any purpose, as the
record date for determining the stockholders entitled to notice of, and


   16

                                      -11-

to vote at, such meeting and any adjournment thereof, to receive such dividend
or distribution, to receive such allotment of rights, or to exercise the rights
in respect of any such change, conversion or exchange of capital stock, or to
express such consent or dissent. In such case only stockholders of record on the
date so fixed shall have such right, notwithstanding any transfer of stock on
the books of the corporation after the record date. In lieu of fixing such
record date, the Board of Directors may close the stock transfer books for all
or any part of such period. In any case in which the Board of Directors does not
fix a record date or provide for the closing of the transfer books, the record
date shall be the thirtieth day next preceding the date of such meeting, the
dividend payment or distribution date, the date for allotment of rights, the
date for exercising of rights in respect of any such change, conversion or
exchange of capital stock, or the date for expressing such consent or dissent,
as the case may be.

     Section 5.4. Lost, Mutilated or Destroyed Certificates. No certificates for
shares of stock of the corporation shall be issued in place of any certificate
alleged to have been lost, mutilated or destroyed, except upon production of
such evidence of the loss, mutilation or destruction and upon indemnification of
the corporation and its agents to such extent and in such manner as the Board of
Directors may prescribe and as required by law.

                Article VI - Miscellaneous Management Provisions

     Section 6.1. Execution of Instruments. Except as otherwise provided in
these By-laws or as the Board of Directors may generally or in particular cases
authorize the execution thereof in some other manner, all instruments,
documents, deeds, leases, transfers, contracts, bonds, notes, checks, drafts and
other obligations made, accepted or endorsed by the corporation shall be signed
by the President or a Vice President, or by the Treasurer or an Assistant
Treasurer, or by the Clerk. Facsimile signatures may be used in the manner and
to the extent authorized generally or in particular cases by the Board of
Directors.

     Section 6.2. Corporate Records. The original, or attested copies, of the
Articles of Organization, By-laws, and records of all meetings of incorporators
and stockholders, and the stock and transfer records, which shall contain the
names of all stockholders and the record address and the amount of stock held by
each, shall be kept in the Commonwealth of Massachusetts at the principal office
of the corporation, or at an office of its Clerk, its resident agent or its
transfer agent. The copies and


   17


                                      -12-

records need not all be kept in the same office. They shall be available at all
reasonable times for inspection by any stockholder for any proper purpose. They
shall not be available for inspection to secure a list of stockholders or other
information for the purpose of selling such list or information or copies
thereof or of using the same for a purpose other than in the interest of the
applicant, as a stockholder, relative to the affairs of the corporation. 

     Section 6.3. Voting of Securities owned by this Corporation. Subject always
to the specific directions of the Board of Directors, (a) any shares or other
securities issued by any other corporation and owned or controlled by this
corporation may be voted in person at any meeting of security holders of such
other corporation by the President of this corporation if he is present at such
meeting, or in his absence by the Treasurer of this corporation if he is present
at such meeting, and (b) whenever, in the judgment of the President, it is
desirable for this corporation to execute a proxy or written consent in respect
to any shares or other securities issued by any other corporation and owned by
this corporation, such proxy or consent shall be executed in the name of this
corporation by the President, without the necessity of any authorization by the
Board of Directors, affixation of corporate seal or countersignature or
attestation by another officer, provided that if the President is unable to
execute such proxy or consent by reason of sickness, absence from the United
States or other similar cause, the Treasurer may execute such proxy or consent.
Any person or persons designated in the manner above stated as the proxy or
proxies of this corporation shall have full right, power and authority to vote
the shares or other securities issued by such other corporation and owned by
this corporation the same as such shares or other securities might be voted by
this corporation.

     Section 6.4. Conflict of Interest. No contract or other transaction of the
corporation shall, in the absence of fraud, be affected or invalidated by the
fact that any stockholder, director or officer of the corporation or any
corporation, firm or association of which he may be a director, officer,
stockholder or member may be a party to or may have an interest, pecuniary or
otherwise, in, any such contract or other transaction, provided that the nature
and extent of his interest was disclosed to, or known by, the entire Board of
Directors before acting on such contract or other transaction. Except in the
case of any contract or other transaction between the corporation and any other
corporation controlling, controlled by or under common control with the
corporation, any director of the corporation who is also a director, officer,
stockholder or




   18


                                      -13-

member of any corporation, firm or association with which the corporation
proposes to contract or transact any business, or who has an interest, pecuniary
or otherwise, in any such contract or other transaction, may not be counted in
determining the existence of a quorum at any meeting of the Board of Directors
which shall authorize any such contract or such transaction, and such director
shall not participate in the vote to authorize any such contract or transaction.
Any such contract or transaction may be authorized or approved by a majority of
the directors then in office and not disqualified by this Section 6.4 to vote on
such matters, even though the disinterested directors do not constitute a
quorum.

     Section 6.5. Indemnification. The corporation shall indemnify each director
and officer against all judgments, fines, settlement payments and expenses,
including reasonable attorneys' fees, paid or incurred in connection with any
claim, action, suit or proceeding, civil or criminal, to which he may be made a
party or with which he may be threatened by reason of his being or having been a
director or officer of the corporation, or, at its request, a director, officer,
stockholder or member of any other corporation, firm or association, or by
reason of his serving or having served, at its request, in any capacity with
respect to any employee benefit plan, and by which he is not so indemnified, or
by reason of any action or omission by him in any such capacity, whether or not
he continues to be a director or officer at the time of incurring such expenses
or at the time the indemnification is made. No indemnification shall be made
hereunder (a) with respect to payments and expenses incurred in relation to
matters as to which he shall be finally adjudged in such action, suit or
proceeding not to have acted in good faith and in the reasonable belief that his
action was in the best interest 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),
or (b) otherwise prohibited by law. The foregoing right of indemnification shall
not be exclusive of other rights to which any director or officer may otherwise
be entitled and shall inure to the benefit of the executor or administrator of
such director or officer.
