          2. The Board of Directors is expressly authorized to adopt, amend or
repeal the By-Laws of the Corporation.
<PAGE>

     SEVENTH. Except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability. No amendment to or repeal of this provision shall apply to or have
any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment.

     EIGHTH. The Corporation shall, to the fullest extent permitted by Section
145 of the General Corporation Law of Delaware, as amended from time to time,
indemnify each person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that he
is or was, or has agreed to become, a director or officer of the Corporation, or
is or was serving, or has agreed to serve, at the request of the Corporation, as
a director, officer or trustee of, or in a similar capacity with, another
corporation, partnership, joint venture, trust or other enterprise (including
any employee benefit plan) (all such persons being referred to hereafter as an
"Indemnitee"), or by reason of any action alleged to have been taken or omitted
in such capacity, against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by or on
behalf of an Indemnitee in connection with such action, suit or proceeding and
any appeal therefrom.

     As a condition precedent to his right to be indemnified, the Indemnitee
must notify the Corporation in writing as soon as practicable of any action,
suit, proceeding or investigation involving him for which indemnity will or
could be sought. With respect to any action, suit, proceeding or investigation
of which the Corporation is so notified, the Corporation will be entitled to
participate therein at its own expense and/or to assume the defense thereof at
its own expense, with legal counsel reasonably acceptable to the Indemnitee.

     In the event that the Corporation does not assume the defense of any
action, suit, proceeding or investigation of which the Corporation receives
notice under this Article, the Corporation shall pay in advance of the final
disposition of such matter any expenses (including attorneys' fees) incurred by
an Indemnitee in defending a civil or criminal action, suit, proceeding or
investigation or any appeal therefrom; provided, however, that the payment of
                                       --------  -------
such expenses incurred by an Indemnitee in advance of the final disposition of
such matter shall be made only upon receipt of an undertaking by or on behalf of
the Indemnitee to repay all amounts so advanced in the event that it shall
ultimately be determined that the Indemnitee is not entitled to be indemnified
by the Corporation as authorized in this Article, which undertaking shall be
accepted without reference to the financial ability of the Indemnitee to make
such repayment; and further provided that no such advancement of expenses shall
                    ------- --------
be made if it is determined that (i) the Indemnitee did not act in good faith
and in a
<PAGE>

manner he reasonably believed to be in, or riot opposed to, the best interests
of the Corporation, or (ii) with respect to any criminal action or proceeding,
the Indemnitee had reasonable cause to believe his conduct was unlawful.

     The Corporation shall not indemnify an Indemnitee seeking indemnification
in connection with a proceeding (or part thereof) initiated by such Indemnitee
unless the initiation thereof was approved by the Board of Directors of the
Corporation. In addition, the Corporation, shall not indemnify an Indemnitee to
the extent such Indemnitee is reimbursed from the proceeds of insurance, and in
the event the Corporation makes any indemnification payments to an Indemnitee
and such Indemnitee is subsequently reimbursed from the proceeds of insurance,
such Indemnitee shall promptly refund such indemnification payments to the
Corporation to the extent of such insurance reimbursement.

     All determinations hereunder as to the entitlement of an Indemnitee to
indemnification or advancement of expenses shall be made in each instance by (a)
a majority vote of the directors of the Corporation consisting of persons who
are not at that time parties to the action, suit or proceeding in question
("disinterested directors"), whether or not a quorum, (b) a majority vote of a
quorum of the outstanding shares of stock of all classes entitled to vote for
directors, voting as a single class, which quorum shall consist of stockholders
who are not at that time parties to the action, suit or proceeding in question,
(c) independent legal counsel (who may, to the extent permitted by law, be
regular legal counsel to the Corporation), or (d) a court of competent
jurisdiction.

     The indemnification rights provided in this Article (i) shall not be
deemed exclusive of any other rights to which an Indemnitee may be entitled
under any law, agreement or vote of stockholders or disinterested directors or
otherwise, and (ii) shall inure to the benefit of the heirs, executors and
administrators of the Indemnitees. The Corporation may, to the extent authorized
from time to time by its Board of Directors, grant indemnification rights to
other employees or agents of the Corporation or other persons serving the
Corporation and such rights may be equivalent to, or greater or less than, those
set forth in this Article.

     NINTH. The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Certificate of Incorporation, in the manner now
or hereafter prescribed by statute and this Certificate of Incorporation, and
all rights conferred upon stockholders herein are granted subject to this
reservation.

     EXECUTED at Boston, Massachusetts, on December 18, 1997.

office, and a director chosen to fill a position resulting from an increase in
the number of directors shall hold office until the next annual meeting of
stockholders and until his successor is elected and qualified, or until his

Directors may be held without notice immediately after and at the same place as
the annual meeting of stockholders.

     2.8 Special Meetings. Special meetings of the Board of Directors may be
held at any time and place, within or without the State of Delaware, designated

any committee designated by the directors may participate in a meeting of the

     4.2 Certificates of Stock. Every holder of stock of the corporation shall
be entitled to have a certificate, in such form as may be prescribed by law and
by the Board of Directors, certifying the number and class of shares owned by
him in the corporation. Each such certificate shall be signed by, or in the name
of the corporation by, the Chairman or Vice-Chairman, if any, of the Board of
Directors, or the President or a Vice President, and the Treasurer or an
Assistant Treasurer, or the Secretary or an Assistant Secretary of the
corporation. Any or all of the signatures on the certificate may be a facsimile.

     Each certificate for shares of stock which are subject to any restriction
on transfer pursuant to the Certificate of Incorporation, the By-Laws,
applicable securities laws or any agreement among any number of shareholders or
among such holders and the corporation shall have conspicuously noted on the
face or back of the certificate either the full text of the restriction or a
statement of the existence of such restriction.

     If the corporation shall be authorized to issue more than one class of
stock or more than one series of any class, the powers, designations,
preferences and relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of each certificate representing shares of such
class or series of stock, provided that in lieu of the foregoing requirements
there may be set forth on the face or back of each certificate representing
shares of such class or series of stock a statement that the corporation will
furnish without charge to each stockholder who so requests a copy of the full
text of the powers, designations, preferences and relative, participating,
optional or other special rights of each class of stock or series thereof and
the qualifications, limitations or restrictions of such preferences and/or
rights.

     4.3 Transfers. Except as otherwise established by rules and regulations
adopted by the Board of Directors, and subject to applicable law, shares of
stock may be transferred on the books of the corporation by the surrender to the
corporation or its transfer agent of the certificate representing such shares
properly endorsed or accompanied by a written assignment or power of attorney
properly executed, and with such proof of authority or the authenticity of
signature as the corporation or its transfer agent may reasonably require.
Except as may be otherwise required by law, by the Certificate of Incorporation
or by these By-Laws, the corporation shall be entitled to treat the record
holder of stock as shown on its books as the owner of such stock for all
purposes, including the payment of dividends and the right to vote with respect
to such stock, regardless of any transfer, pledge or other disposition of such
stock until the shares have been transferred on the books of the corporation in
accordance with the requirements of these By-Laws.

     4.4 Lost, Stolen or Destroyed Certificates. The corporation may issue a new
certificate of stock in place of any previously issued certificate alleged to
have been lost, stolen, or destroyed, upon such terms and conditions as the
Board of Directors may prescribe, including the presentation of reasonable
evidence of such loss, theft or destruction and the giving of such indemnity as
the Board of Directors may require for the protection of the corporation or any
transfer agent or registrar.

     4.5 Record Date. The Board of Directors may fix in advance a date as a
record date for the determination of the stockholders entitled to notice of or
to vote at any meeting of stockholders or to express consent (or dissent) to
corporate action in writing without a meeting, or entitled to receive payment of
any dividend or other distribution or allotment of any rights in respect of any
change, conversion or exchange of stock, or for the purpose of any other lawful
action. Such record date shall not be more than 60 nor less than 10 days before
the date of such meeting, nor more than 10 days after the date of adoption of a
record date for a written consent without a meeting, nor more than 60 days prior
to any other action to which such record date relates.

     If no record date is fixed, the record date for determining stockholders
entitled to notice of or to vote at a meeting of stockholders shall be at the
close of business on the day before the day on which notice is given, or, if
notice is waived, at the close of business on the day before the day on which
the meeting is held. The record date for determining stockholders entitled to
express consent to corporate action in writing without a meeting, when no prior
action by the Board of Directors is necessary, shall be the day on which the
first written consent is properly delivered to the corporation. The record date
for determining stockholders for any other purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolution
relating to such purpose.

     A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

of such notice either in writing signed by the person entitled to such notice or
such person's duly authorized attorney, or by telegraph, cable or any other
available method, whether before, at or after the time stated in such waiver, or
the appearance of such person or persons at such meeting in person or by proxy,
shall be deemed equivalent to such notice.

     5.4 Voting of Securities. Except as the directors may otherwise designate,
the President or Treasurer may waive notice of, and act as, or appoint any
person or persons to act as,

substitution) at, any meeting of stockholders or shareholders of any other
corporation or organization, the securities of which may be held by this
corporation.

     5.5 Evidence of Authority. A certificate by the Secretary, or an Assistant
Secretary, or a temporary Secretary, as to any action taken by the stockholders,
directors, a committee or any officer or representative of the corporation shall
as to all persons who rely on the certificate in good faith be conclusive

between the corporation and one or more of the directors or officers, or between
the corporation and any other corporation, partnership, association, or other
organization in which one or more of the directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or a committee of the
Board of Directors which authorizes the contract or transaction or solely
because his or their votes are counted for such purpose, if:

     (1) The material facts as to his relationship or interest and as to the
contract or transaction are disclosed or are known to the Board of Directors or
the committee, and the Board or committee in good faith authorizes the contract
or transaction by the affirmative votes of a majority of the disinterested
directors, even though the disinterested directors be less than a quorum;

     (2) The material facts as to his relationship or interest and as to the
contract or transaction are disclosed or are known to the stockholders entitled
to vote thereon, and the contract or transaction is specifically approved in
good faith by vote of the stockholders; or

     (3) The contract or transaction is fair as to the corporation as of the
time it is authorized, approved or ratified, by the Board of Directors, a
committee of the Board of Directors, or the stockholders.

     Common or interested directors may be counted in determining the presence
of a quorum at a meeting of the Board of Directors or of a committee which
authorizes the contract or transaction.

     5.8 Severability. Any determination that any provision of these By-Laws is
for any reason inapplicable, illegal or ineffective shall not affect or
invalidate any other provision of these By-Laws.

                          ARTICLE 6 - Indemnification

     6.1 Right to Indemnification. Each person who was or is made a party or is
threatened to be made a party to or is otherwise involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative (a
"Proceeding"), by reason of being or having been a director or officer of the
corporation or serving or having served at the request of the corporation as a
director, trustee, officer, employee or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, including service with
respect to an employee benefit plan (an "Indemnitee"), shall be indemnified and
held harmless by the corporation to the fullest extent authorized by the
Delaware General Corporation Law, as the same exists or may hereafter be amended
(but, in the case of any such amendment, only to the extent that such amendment
permits the corporation to provide broader indemnification rights than permitted
prior thereto) (as used in this Article 6, the "Delaware Law"), against all
expense, liability and loss (including attorneys' fees, judgments, fines, ERISA
excise taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such Indemnitee in connection therewith and such indemnification
shall continue as to an Indemnitee who has ceased to be a director, trustee,
officer, employee or agent and shall inure to the benefit of the Indemnitee's
heirs, executors and administrators; provided, however, that, except as provided
in Section 6.2 hereof with respect to Proceedings to enforce rights to
indemnification, the corporation shall indemnify any such Indemnitee in
connection with a Proceeding (or part thereof) initiated by such Indemnitee only
if such Proceeding (or part thereof) was authorized by the Board of Directors of
the corporation. The right to indemnification conferred in this Article 6 shall
be a contract right and shall include the right to be paid by the corporation
the, expenses (including attorneys' fees) incurred in defending any such
Proceeding in advance of its final disposition (an "Advancement of Expenses");
provided, however, that an Advancement of Expenses incurred by an Indemnitee
shall be made only upon delivery to the corporation of an undertaking, by or on
behalf of such Indemnitee, to repay all amounts so advanced if it should
ultimately be determined by final judicial decision from which there is no
further right to appeal (a "Final Adjudication") that such Indemnitee is not
entitled to be indemnified for such expenses under this Article 6 or otherwise.

     6.2 Right of Indemnitee to Bring Suit. If a claim under Section 6.1 hereof
is not paid in full by the corporation within sixty days after a written claim
has been received by the corporation, except in the case of a claim for an
Advancement of Expenses, in which case the applicable period will be twenty
days, the Indemnitee may at any time thereafter bring suit against the
corporation to recover the unpaid amount of the claim. If successful in whole or
in part in any such suit, or in a suit brought by the corporation to recover an
Advancement of Expenses, the Indemnitee shall be entitled to be paid also the
expense of prosecuting or defending such suit. In (i) any suit brought by an
Indemnitee to enforce a right to

                                       13
<PAGE>

indemnification hereunder (but not in a suit brought by the Indemnitee to
enforce a right to an Advancement of Expenses) it shall be a defense that, and
(ii) in any suit by the corporation to recover an Advancement of Expenses, the
corporation shall be entitled to recover such expenses upon a Final Adjudication
that, the Indemnitee has not met the applicable standard of conduct set forth in
the Delaware Law. In any suit brought by the Indemnitee to enforce a right to
indemnification or to an Advancement of Expenses hereunder, or by the
corporation to recover an Advancement of Expenses, the burden of proving that
the Indemnitee is not entitled to be indemnified, or to such Advancement of
Expenses, under this Article 6 or otherwise shall be on the corporation.

     6.3 Non-Exclusivity of Rights. The rights to indemnification and to the
Advancement of Expenses conferred in this Article 6 shall not be exclusive of
any other right which any person may have or hereafter acquire under any
statute, provisions of the corporation's Certificate of Incorporation or these
by-laws, agreement, vote of stockholders or disinterested directors or
otherwise.

     6.4 Insurance. The corporation may maintain insurance, at its expense, to
protect itself and any director, officer, employee or agent of the corporation
or another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the corporation would
have the power to indemnify such person against such expense, liability or loss
under this Article 6 or under the Delaware Law.

     6.5 Indemnification of Employees and Agents of the Corporation. The
corporation may, to the extent authorized from time to time by the board of
directors, grant rights to indemnification, and to the Advancement of Expenses,
to any employee or agent of the corporation to the fullest extent of the
provisions of this Article 6 with respect to the indemnification and Advancement
of Expenses of directors and officers of the corporation.

                             ARTICLE 7 - Amendments

     7.1 By the Board of Directors. These By-Laws may be altered, amended or
repealed or new by-laws may be adopted by the affirmative vote of the Required
Percentage of the directors present at any regular or special meeting of the
Board of Directors at which a quorum is present.

     7.2 By the Stockholders. These By-Laws may be altered, amended or repealed
or new by-laws may be adopted by the affirmative vote of the holders of
sixty-six and two-thirds percent of the shares of the capital stock of the
corporation issued and outstanding and entitled to vote at any regular meeting
of stockholders, or at any special meeting of stockholders, provided notice of
such alteration, amendment, repeal or adoption of new by-laws shall have been
stated in the notice of such special meeting.
