"Corporate Seal."

          Section 3. Offices. The initial principal office of the Corporation
shall be located in Sandy Hook, Connecticut. The Board of Directors (the
"Board") may from time to time, in its discretion, or as the activities of the
Corporation may require, establish a different location for the Corporation's
principal office and may establish such other offices of the Corporation, each
which may be located within or without the State of Connecticut.

                      ARTICLE II. MEETINGS OF SHAREHOLDERS

          Section 1. Place of Meetings. Meetings of the shareholders of the
Corporation shall be held at the principal office of the Corporation, or at such
other place, either within or without the State of Connecticut, as may be fixed
by the Board or the President of the Corporation and stated in the notice of
meeting or in a duly executed waiver of notice thereof.

          Section 2. Annual Meeting. An annual meeting of the shareholders shall
be held each year at such place, date and time as the Board shall from time to
time prescribe. At each annual meeting of the shareholders, the shareholders
shall elect the Board for the ensuing year and shall transact such other
business as may properly come before the meeting. Unless the Certificate of
Incorporation of the Corporation or these Bylaws provide otherwise, notice of an
annual meeting need not include a description of the purpose or purposes for
which the meeting is called.

          Section 3. Special Meetings. Special meetings of the shareholders
shall be held: (1) on call of the Board or the President of the Corporation, or

be cast on any issue proposed to be considered at the proposed special meeting
sign, date and deliver to the Corporation's Secretary one or more written
demands for the meeting describing the purpose or purposes for which the meeting
is to be held. Notice of a special meeting of shareholders shall include a

shareholders' meeting may be conducted at the special meeting of the
shareholders that is the subject of such meeting notice.

          Section 4. Action without a Meeting. Any action which may be taken at
a meeting of shareholders may be taken without a meeting by a written consent
setting forth the action so taken or to be taken, signed by all of the persons
who would be entitled to vote upon such action at a meeting or by their duly
authorized attorneys. Unless otherwise fixed by the



Board, the record date for determining shareholders entitled to take action
without a meeting is the date that the first shareholder signs the consent for
the proposed action.

          Section 5. Notice. (a) Except as otherwise required by law, written
notice of each meeting of shareholders, stating the place, day and hour of the
meeting and, in the case of a special meeting, the purpose or purposes for which
the meeting is called, shall be delivered not less than ten (10) days nor more
than sixty (60) days before the date of the meeting, to each shareholder of
record entitled to vote at such meeting by leaving such notice with such
shareholder personally, or by depositing such notice in the United States mails
in a postage prepaid envelope addressed to such shareholder at such
shareholder's address as it appears on the stock transfer books of the
Corporation. Unless the Connecticut Business Corporation Act, as the same may be
amended from time to time (the "Act") or the Certificate of Incorporation of the
Corporation require otherwise, the Corporation is required to give notice only
to shareholders entitled to vote at the meeting.

          (b) If an annual or special shareholders' meeting is adjourned to a
different date, time or place, notice need not be given of the new date, time or
place if the new date, time or place is announced at the meeting before
adjournment. If a new record date for the adjourned meeting is or must be fixed,
however, notice of the adjourned meeting must be given to persons who are
shareholders as of the new record date.

          Section 6. Waiver of Notice. (a) A shareholder may waive any notice of
a meeting before or after the date and time stated in the notice of a meeting.
The waiver must be in writing, signed by the shareholder entitled to the notice
and delivered to the Corporation for inclusion in the minutes or filing with the
corporate records.

          (b) A shareholder's attendance at a meeting (1) waives objection to
lack of notice or defective notice, unless the shareholder at the beginning of
the meeting objects to holding the meeting or transacting business at the
meeting; and (2) waives objection to consideration of a particular matter at the
meeting that is not within the purpose or purposes described in the meeting
notice, unless the shareholder objects to considering the matter when presented.

          Section 7. Voting Entitlement of Shares. Except as otherwise required
by law or provided in the Certificate of Incorporation of the Corporation, each
outstanding share of voting stock, regardless of class, is entitled to one vote
on each matter voted on at a shareholders' meeting.

          Section 8. Proxies. A shareholder may vote such shareholder's shares
in person or by proxy. A shareholder may appoint a proxy to vote or otherwise
act for such shareholder by signing an appointment form, either personally or by
such shareholder's attorney-in-fact.

          Section 9. Shareholders' Quorum and Voting Requirements. A majority of
the votes entitled to be cast on a matter constitutes a quorum for action on
that matter. Once a share is represented for any purpose at a meeting, it is
deemed present for quorum purposes for the remainder of the meeting and for any
adjournment of that meeting, unless a new record date is or must be set for that
adjourned meeting.

          Section 10. Votes Required for Shareholders' Action. Unless the Act or
the Certificate of Incorporation require a greater number of affirmative votes,
actions to be voted upon by the shareholders (other than the election of
directors) at a meeting at which quorum is present shall be approved if the
votes cast by shares entitled to vote on such action exceed the votes cast in
opposition to such action.

          Section 11. Votes Required for Election of Directors. Unless otherwise
provided in the Certificate of Incorporation, directors shall be elected by a

person or by proxy, at any special meeting of shareholders, may, by the
affirmative vote of a majority of voting power of the shares represented at such
meeting and entitled to vote thereat, adjourn from time to time as they see fit,
whether or not such number constitutes a quorum, and no notice of such
adjournment need be given.

this means is deemed to be present in person at the meeting.

          Section 8. Notice of Meeting. (a) If the date, time and place of
regular meetings is established in advance by the Board, such meetings may be
held without notice of the date, time, place or purpose thereof.

transacting business at the meeting and does not thereafter vote for or assent
to action taken at the meeting.

          Section 10. Quorum and Voting. (a) A quorum for a meeting of the Board
consists of a majority of the number prescribed, or if no number is prescribed,
a majority of the directors in office at the time the meeting begins.

          (b) If a quorum is present when a vote is taken, the affirmative vote
of a majority of directors present is the act of the Board.

or in the right of the Corporation or otherwise, to which such individual was or
is a party or is threatened to be made a party by reason of such individual's
