purpose may be called by the Board of Directors or the President, and shall be
called by the President at the written request of the holders of record of not
less than one-tenth of the voting power of all outstanding shares of the
Corporation entitled to vote at such meeting.  Special meetings shall be held at
such time as may be fixed in the call and stated in the notice of meeting or
waiver thereof.  At any such special meeting only such business may be
transacted as is related to the purposes set forth in the notice of meeting.

     SECTION 3.  Place of Meeting.  Meetings of shareholders shall be held at
                 ----------------                                            
such place, within or without the State of Connecticut or the United States of
America, as may be fixed in the call and notice of meeting or waiver thereof.

     SECTION 4.  Notice of Meetings.  Notice of each meeting of shareholders
                 ------------------

whether before or after the meeting.  The attendance of any shareholder at a
meeting, in person or by proxy, without protesting prior to the conclusion of
the meeting the lack of notice of such meeting, shall constitute a waiver of

     SECTION 6.  Closing of Transfer Books or Fixing of Record Date.  For the
                 --------------------------------------------------          
purpose of determining shareholders entitled to notice of or to vote at any
meeting of shareholders or any adjournment thereof, or shareholders entitled to
receive payment of any dividends, or in order to make a determination of
shareholders for any other proper purpose, the Board of Directors of the
Corporation may provide that the stock transfer books shall be closed for a
stated period but not to exceed, in any case, seventy days.  If the stock
transfer books shall be closed for the purpose of determining shareholders
entitled to notice of or to vote at a meeting of shareholders, such books shall
be closed for at least ten full days immediately preceding such meeting.  In
lieu of closing stock transfer books, the Board of Directors may fix in advance
a date as the record date of any such determination of shareholders, such date
in any case to be not more than seventy days and, in case of a meeting of
shareholders, not less than ten full days prior to the date on which the
particular action requiring such determination of shareholders is to be taken.
If the 

 
                                      -3-

stock transfer books are not closed and no record date is fixed for a
determination of shareholders entitled to notice of or to vote at a meeting of
shareholders or a determination of shareholders entitled to receive payment of a
dividend, the date on which notice of the meeting is mailed or the date on which
the resolution of the Board of Directors declaring such dividend is adopted, as
the case may be, shall be the record date for determination of shareholders.
When a determination of shareholders entitled to vote at any meeting of
shareholders has been made as provided in this section, such determination shall
apply to any adjournment thereof. A record date, or date for closing the stock
transfer books, is effective as of the close of business on such date unless
another hour is designated by the resolution of the Board of Directors.

     SECTION 7.  Voting Lists.  The officer or agent having charge of the stock
                 ------------                                                  
transfer books for shares of the Corporation shall make a complete list of the
shareholders entitled to vote at each meeting of shareholders or any adjournment
thereof, arranged in alphabetical order with the address of and the number of
shares by each.  Such list or other equivalent record shall, for a period of
five days prior to such meeting, be kept on file at the principal office of the
Corporation or at the office or place of business of a transfer agent in this
state and shall be subject to inspection by any shareholder during usual
business hours for any proper purpose.  Such list or other equivalent record
shall also be produced and kept at the time and place of the meeting and shall
be subject for any such proper purpose to such inspection during the whole time
of the meeting.

     SECTION 8.  Qualification of Voters.  Except as may otherwise be provided
                 -----------------------                                      
in the Certificate of Incorporation, every shareholder of record shall be
entitled at every meeting of shareholders to one vote for every share standing
in his name on the record of shareholders.

 
                                      -4-

     Shares of the Corporation standing in the name of another domestic or
foreign corporation of any type or kind may be voted by such officer, agent or
proxy as the by-laws or similar regulations of such corporation may provide, or
in the absence of such provision, as the Board of Directors of such corporation
may determine.

     Treasury shares shall not be shares entitled to vote or to be counted in
determining the total number of outstanding shares of the Corporation.

     SECTION 9.  Quorum.  At any meeting of the shareholders the presence, in
                 ------                                                      
person or by proxy, of the holders of a majority of the shares entitled to vote
thereat shall constitute a quorum for the transaction of any business except
where a greater number is otherwise provided by law.  When a quorum is once
present to organize a meeting, it is not broken by the subsequent withdrawal of
any shareholders.  A majority of the shareholders present, in person or by
proxy, may adjourn the meeting despite the absence of a quorum.

     SECTION 10. Proxies.  Every shareholder entitled to vote at a meeting of
                 -------                                                     
shareholders, to waive notice of such meeting or to express consent or dissent
without meeting may authorize another person or persons in writing to act for
him by proxy.  Every proxy must be signed by the shareholder or his attorney-in-
fact.  No proxy shall be valid after the expiration of eleven months from the
date thereof unless otherwise provided in the proxy, provided in no event shall
a proxy be valid after ten years from its date of execution.  Every proxy shall
be revocable at the pleasure of the shareholder executing it, except as
otherwise provided therein and as permitted by law.  The attendance at any
meeting by the shareholder who shall have previously given a proxy applicable
thereto shall not, as such, have the effect of revoking the proxy.  The
Corporation may treat any proxy as not revoked and in full force and effect
until it receives a duly executed 

 
                                      -5-

instrument revoking it or a proxy bearing a later date or, in the event of death
or incapacity of the shareholder executing the same, written notice of such
death or incapacity.

     SECTION 11. Voting.  Directors shall be elected by a plurality of the
                 ------                                                   
votes cast at a meeting of shareholders when a quorum is present by the holders
of shares entitled to vote in the election, in person or by proxy.  Whenever any
corporate action, other than the election of directors, is to be taken by vote
of the shareholders, it shall, except as otherwise require by law, be authorized
by a majority of the votes cast in person or by proxy at a meeting when a quorum
is present.

     SECTION 12. Action Without a Meeting.  Whenever the shareholders are
                 ------------------------                                
required or permitted to take any action by vote, such action may be taken
without a meeting on written consent, setting forth the action so taken, signed
by the holders of all outstanding shares entitled to vote thereon.

nine as may be fixed from time to time by resolution adopted by the shareholders
or by the Board.  In the absence of such resolution, the number of directors
shall be the number of directors elected at the preceding annual meeting of
shareholders.  The reduction of the number of directors shall not remove any
director in office or shorten his term.  When all of the shares are owned by
less than three 

 
                                      -6-

shareholders, the number of directors may be less than three but not less than
the number of shareholders.

     SECTION 3.  Election and Term of Directors.  At each annual meeting of
                 ------------------------------                            
shareholders, directors shall be elected to hold office until the next annual

any time by giving written notice to the Board of Directors or to the President

resolution adopted by the shareholders or the Board of Directors, shall be
filled by vote of the shareholders.  Vacancies occurring in the Board of
Directors for any other reason whatsoever, including the removal of directors
without cause, shall be filled by vote of the shareholders.  A director elected

each consisting of two or more directors. The Board of Directors may designate
one or more directors as alternate members of any such committee, who may
replace any absent member or members at any meeting of such committee.

     The designation of such executive committee or other committee shall not
operate to relieve the Board of Directors, or any member thereof, of any
responsibility imposed by law.  The executive committee, when the Board of
Directors is not in session, shall have and may exercise all of the authority of
the Board of Directors except to the extent, if any, that such authority shall
be limited by these By-Laws, by the resolution appointing the executive
committee or by law.  Each such other committee shall have and may exercise such
powers as may be authorized in the resolution appointing such other committee
and permitted by law.  Neither the executive committee nor such other committees
shall have the authority of the Board of Directors with respect to amending the
certificate of incorporation, adopting a plan of merger or consolidation,
recommending to the shareholders a voluntary dissolution of the Corporation or a
revocation thereof, or amending the By-Laws of the Corporation.

     SECTION 8.  Compensation of Directors.  The Board of Directors shall have

     SECTION 3.  Quorum; Action by the Board; Adjournment.  At all meetings of

a meeting if all members of the Board of Directors or of the committee consent
in writing to the adoption of a resolution authorizing the action, provided that
the number of directors then in office or serving on such committee and taking
such action shall constitute a quorum for such action.  Such resolution and the
written consent thereto by the members of the Board of Directors or the
committee shall be filed with the minutes of the proceedings of the Board of
Directors or the committee.

present at a meeting of the Board of Directors or any committee thereof at which
action on any corporate matter is taken shall be presumed to have assented to
the action taken unless his dissent shall be entered in the minutes of the
meeting or unless he shall file his written dissent to such action with the
person acting as the secretary of the meeting before the adjournment thereof or

allowing all persons participating in the meeting to hear each other at the same

meeting.

                                  ARTICLE IV.
                                  -----------

qualified.  Any officer may be removed by the Board of Directors with or without
