are intended to be consistent with 33-320a of the Connecticut Stock Corporation
Act.

         Section 1. Definitions. As used in this Article:

         "Indemnified Person" includes any person (or such person's legal
representative) who is or was a director, officer, employee, agent or
shareholder of the corporation and any person who is or was serving at the
request of the corporation as a director, officer, partner, trustee, employee or
agent of another enterprise; and any director, officer or employee who is or

                                       36
<PAGE>   3
was serving at the request of the corporation as a fiduciary of an employee
benefit plan or trust maintained for the benefit of employees of the corporation
or employees of any other enterprise;

         "Loss" includes judgements, fines (including ERISA excise taxes),
penalties, and expenses (including amounts paid in settlement and reasonable
attorneys' fees and disbursements);

         "Party" includes a person who was, is or is threatened to be made, a
defendant or respondent in a Proceeding; and

         "Proceeding" means any threatened, pending or completed action, suit or
proceeding, or appeal thereof, whether civil, criminal, administrative or
investigative, involving any person in his capacity as an Indemnified Person.

         Section 2. Indemnification.

         (a) For actions other than by or in the right of the corporation, the
corporation shall indemnify any Indemnified Person made a Party to any
Proceeding against any Loss actually incurred by the Indemnified Person in
connection with such Proceeding, except as otherwise provided in Section 3(a).

         (b) For actions by or in the right of the corporation, the corporation
shall indemnify any Indemnified Person made a Party to any Proceeding against
reasonable expenses actually incurred by the Indemnified Person in connection
with such Proceeding in relation to matters as to which such Indemnified Person
is finally adjudged not to have breached his duty to the corporation, or where
the court, on application as provided in Section 5 below, shall have determined
that such Indemnified Person is fairly and reasonably entitled to be
indemnified, and then for such amount as the court shall determine. The
corporation shall not so indemnify any Indemnified Person for amounts paid to
the corporation, to a plaintiff or to counsel for a plaintiff in settling or
otherwise disposing of such a Proceeding, with or without court approval; or for
expenses including attorneys' fees incurred in defending such a Proceeding which
is settled or otherwise disposed of without court approval.

         Section 3. Exclusions From Indemnification. The indemnification
provided for in Section 2(a) above shall not be provided to any Indemnified
Person unless (a) the Indemnified Person was successful on the merits in the
defense of any such Proceeding, or (b) it shall be concluded under Section 4
below that such Indemnified Person acted in good faith and in a manner he
reasonably believed to be in the best interests of the corporation, or, if
applicable, the best interests of the participants and beneficiaries of the
employee benefit plan or trust (and consistent with the provisions of such plan
or trust) and, with respect to any criminal action, that he had no reasonable
cause to believe his conduct was unlawful, or (c) the court, on application as
provided in Section 5 below shall have determined that such Indemnified Person
is fairly and reasonably entitled to be indemnified, and then for such amount as
the court shall determine; provided, however, that if the claim giving rise to
indemnification under Section 2(a) is based upon the Indemnified Person's
purchase or sale of securities of the corporation or of another enterprise, the
corporation shall only indemnify such Indemnified Person upon the determination
of a court as described in Section 3(c) herein.

         Section 4. Conclusion of Good Faith. The conclusion of good faith
provided for in Section 3(b) above may be reached by any one of the following:
(a) the board of directors of the corporation by a consent in writing signed by
a majority of those directors who were not parties to such Proceeding; (b)
independent legal counsel selected by a consent in writing signed by a majority
of those directors who were not parties to such Proceeding; (c) in the case of
any employee or agent who is not an officer or director of the corporation, the
corporation's general counsel; or (d) the shareholders of the corporation by the
affirmative vote of at least a majority of the voting power of shares not owned
by parties to such Proceeding. The Indemnified Person may also apply to a court
for such conclusion, upon application as provided in Section 5 below, even
though the conclusion reached under any of the foregoing shall have been adverse
to the Indemnified Person. The termination of any Proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere or its equivalent shall
not, of itself, create a presumption that the Indemnified Person did not satisfy
the good faith standard of conduct required under Section 3(b).

         Section 5. Application to the Court. Where an application for
indemnification or an application for a conclusion of good faith as provided in
this Article is made to a court, it shall be made to the court in which the
Proceeding is pending or to the superior court for the judicial district where
the principal office of the corporation is located. The application shall
conform to the applicable rules of the court. Notice of such application shall
be provided to the corporation, and to any other persons as the court may
designate.

         Section 6. Advance Payment of Expenses. The corporation shall pay the
indemnifiable expenses of an Indemnified Person in advance of the final
disposition of any Proceeding except to the extent that the defense of a claim
against the Indemnified Person is undertaken pursuant to any directors' and
officers' liability insurance maintained by the corporation. 

                                       37
<PAGE>   4
The advance payment of such expenses will be subject to the Indemnified Person's
first agreeing in writing to repay such advances if it is thereafter determined
that the Indemnified Person was not entitled to indemnification under this
Article.

         Section 7. Notices, Insurance. Promptly after receipt by the
Indemnified Person of a notice of or threat of commencement of any Proceeding
for which indemnification may be sought from the corporation under this Article,
the Indemnified Person shall notify the corporation in writing of such notice or
threat. If, at the time of receipt of such notice, the corporation has any
directors' or officers' liability insurance in effect, the corporation will give
prompt notice of the commencement of such Proceeding to the insurer, and take
all necessary and desirable action to cause such insurer to pay any amounts and
expenses which the Indemnified Person is obligated to pay as a result of such
Proceeding, in accordance with the terms of such insurance policies. The
corporation may obtain insurance providing for greater indemnification than that
described in this Article.

Article VII. Miscellaneous.

         Section 1. Fiscal Year. The fiscal year of the corporation shall end on
the last calendar day of December.

         Section 2. Informal directors or committee action. Except for an
amendment to these by-laws, any action required or permitted to be taken at any
meeting of the Board of Directors or any committee thereof, may be taken without
a meeting if written consent thereto is signed by all members of the Board or
such committee, as the case may be, and such consent is filed with the minutes
of proceedings of the Board or Committee.

         Section 3. Waivers of notice. Whenever any notice of the time, place or
purposes of any meeting of the stockholders, directors or any committee is
required to be given by law, the Certificate of Incorporation or these By-laws,
a written waiver thereof, signed by any person entitled to such notice and filed
with the records of the meeting, whether before or after the holding thereof, or
actual attendance at such meeting in person or by proxy, shall be deemed
equivalent to the giving of such notice to such person.

         Section 4. Amendments. Except as otherwise provided by law or the
Certificate of Incorporation, the Board of Directors shall have power to adopt,
amend or repeal the By-laws of the corporation.

                                       38
