held in each year during the month of January on a day to be designated by the
Board of Directors, and at the time and place (either within or without the
State of Delaware) as shall be fixed by the Board of Directors and specified in
the notice of meeting for the purpose of electing directors and transacting such
other business as may properly be brought before the meeting.

      Section 2. Special Meeting A Special Meeting of stockholders may be called
at any time by the President or by the Board of Directors or by the President or
the Secretary at the request in writing by the holders of a majority of the

Any such request shall state the purpose or purposes of the proposed meeting.
Special meetings shall be held at such time and place (either within or without
the State of Delaware) as shall be specified in the notice thereof. Business
transacted at any special meeting of stockholders shall be confined to the
purposes set forth in the notice thereof.

      Section 3. Notice of Meetings Written notice of the time, place and
purpose of every meeting or stockholders, (and, if other than an annual meeting,
indicating the person or persons at whose direction the meeting is being
convoked), shall be given to each stockholder of record entitled to vote at such
meeting and to each stockholder who, by reason of any action proposed at such
meeting, would be entitled to have his stock appraised if such action were
taken, not less than ten nor more than sixty days prior to the date set for the
meeting, either personally or by mailing said notice by first class mail to each
stockholder at his address appearing on the stock book of the Corporation or at
such other address supplied by him in writing to the Secretary of the
Corporation for the purpose of receiving notice. Notice by mail shall be deemed

      A written waiver of notice setting forth the purposes of the meeting for
which notice is waived, signed by the person or persons entitled to such notice,
whether before or after the time of the meeting stated therein, shall be deemed
equivalent to the giving of such notice. The attendance by a stockholder at a
meeting either in person or by proxy without protesting the lack of notice
thereof shall constitute a waiver of notice of such stockholder.

      All notice given with respect to an original meeting shall extend to any
and all adjournments thereof and such business as might have been transacted at
the original meeting may be transacted at any adjournment thereof; no notice of
any adjourned meeting need be given if an announcement of the time and place of

meeting of stockholders, the stockholders entitled to vote thereat, present in
person or represented by proxy, shall have power to adjourn the meeting from
time to time, without notice other than announcement at the meeting, until a
quorum shall be present or represented. At such adjourned meeting at which a
quorum shall be present or represented, any business may be transacted which
might have been transacted at the meeting as originally notified. When a


                                       3


quorum is once present to organize a meeting, such quorum is not deemed broken
by the subsequent withdrawal of any stockholders.

      Section 5. Voting Every stockholder entitled to vote at any meeting shall
be entitled to one vote for each share of stock entitled to vote and held by him
of record on the date fixed as the record date for said meeting and may so vote
in person or by proxy. At all elections of directors when a quorum is present, a
plurality of the votes cast by the holders of shares entitled to vote shall
elect and any other corporate action, when a quorum is present, shall be
authorized by a majority of the votes cast by the holders of shares entitled to
vote thereon except as may otherwise be provided by statute.

      Section 6. Proxies Every proxy must be signed by the stockholder entitled
to vote or by his duly authorized attorney-in-fact and shall be valid only if
filed with the Secretary of the Corporation or with the Secretary of the meeting
prior to the commencement of voting on the matter in regard to which said proxy
is to be voted. No proxy shall be valid after the expiration of eleven months
from the date of its execution unless otherwise expressly provided in the proxy.
Every proxy shall be revocable at the pleasure of the person executing it except
as otherwise provided by Section 212 of the General Corporation Law. Unless the
proxy by its terms provides for a specific revocation date and except as
otherwise provided by statute, revocation of a proxy shall not be effective
unless and until such revocation is executed in writing by the stockholder who
executed such proxy and the


                                       4


revocation is filed with the Secretary of the Corporation or with the Secretary
of the Meeting prior to the voting of the proxy.

      Section 7. Stockholders' List A list of stockholders as of the record
date, certified by the Secretary of the Corporation or by a transfer agent
appointed by the Board of Directors shall be prepared for every meeting of
stockholders and shall be produced by the Secretary or some other officer of the
Corporation thereat.

      Section 8. Inspectors at Meetings In advance of any stockholders' meeting,
the Board of Directors may appoint one or more inspectors to act at the meeting
or at any adjournment thereof and if not so appointed the person presiding at
any such meeting may, and at the request of any stockholder entitled to vote
thereat shall, appoint one or more inspectors. Each inspector, before entering
upon the discharge of his duties as set forth in Section 231 of the General
Corporation Law, shall take and sign an oath faithfully to execute the duties of
inspector at such meeting with strict impartiality and according to the best of
his ability.

      Section 9. Conduct of Meeting All meetings of stockholders shall be
presided over by the President, or if he is not present by a chairman thereby
chosen by the stockholders at the meeting. The Secretary of the Corporation, or

but if neither the Secretary nor the Assistant Secretary is present the Chairman
of the meeting shall appoint any person present to act as secretary of the
meeting.

      Section 10. Stockholder Action Without Meetings Any action required by the
General Corporation Law to be taken at any annual or special meeting of
stockholders, or any action which may be taken at any annual or special meeting
of stockholders, may be taken without a meeting, without prior notice and
without a vote, if a consent in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted. Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing. Action taken pursuant to this paragraph shall be
subject to the provisions of Section 228 of the General Corporation Law.

the entire Board shall consist of one or more members,


                                       6


as may be fixed by resolution of the Board of Directors or by the stockholders
entitled to vote for the election of directors at an annual meeting, provided
that any such action of the Board shall require the vote of a majority of the
entire Board. The phrase "entire Board" as used herein means the total number of
directors which the Corporation would have if there were no vacancies. The term
of any incumbent director shall not be shortened by any such action by the Board
of Directors or by the stockholders.

      Each director shall be at least twenty-one years of age. A director need

of Delaware.

      Section 3. Election, Term and Vacancies Except as otherwise provided in
this Section, all directors shall be elected at an annual meeting of
stockholders, and all directors who are elected in the interim to fill vacancies

meetings of stockholders called for the election of directors and/or the removal
of one or more directors and for the filling of any vacancy in that connection,

directors or from vacancies occurring in the Board, but not, except as
hereinafter provided, in the case of a vacancy occurring by


                                       7


reason of removal of a director by the stockholders, may be filled by the vote
of a majority of the directors, then remaining in office, although less than a
quorum may exist.

      In the case of a vacancy occurring in the Board of Directors by reason of
the removal of one or more directors by action of the stockholders, such vacancy
may be filled by the stockholders at a special meeting duly called for such
purpose.

      In the event a vacancy is not filled by such election by stockholders,
whether or not the vacancy resulted from the removal of a director with or
without cause, a majority of the directors then remaining in office, although
less than a quorum, may fill any such vacancy.

      Section 4. Removal The Board of Directors may, at any time, with cause,
remove any director.

annual meeting of stockholders, at the same place at which such stockholders'
meeting is held.

      Regular meetings of the Board of Directors shall be held at such time and
place, within or outside of the State of Delaware, as may be fixed by resolution
of the Board, and when so fixed, no


                                       8


further notice thereof need be given. Regular meetings not fixed by resolution
of the Board may be held on notice at such time and place as shall be determined
by the Board.

      Special meetings of the Board of Directors may be called on notice at any
time by the President or by a majority of the directors then in office and shall
be called by the President or the Secretary at the written request of a majority
of the directors then in office.

      Section 6. Notice of Meeting In the case of all special meetings and of
regular meetings not fixed by resolution of the Board, written notice of the
time, place and purposes of each such meeting shall be mailed to each director,
addressed to his residence or usual place of business, not less than four days
before the date on which such meeting is to be held, or shall be sent to such
address by telegraph, or be given personally, or by telephone, not less than two
days before the date on which such meeting is to be held.

      Any meeting of the Board of Directors for which notice is required by
these By-Laws or by statute need not be given to any director who submits a
signed waiver of notice whether before or after the meeting, or who attends the
meeting without protesting prior thereto or at its commencement the lack of
notice to him. All signed waivers of notice shall be filed with the minutes of
the meeting.

      Section 7. Conduct of Meetings The President, if present, shall preside at
all meetings of directors. At all meetings at


                                       9


which the President is not present, any other director chosen by the Board,
shall preside.

      Section 8. Quorum, Adjournment, Voting A majority of the entire Board
shall be requisite and shall constitute a quorum at all meetings of the Board of
Directors for the transaction of business, except where a vacancy or vacancies
prevents such majority, whereupon a majority of the directors then in office
shall constitute a quorum, provided such majority shall constitute at least
one-third of the entire Board.

      A majority of the directors present at any meeting, whether or not a
quorum is present, may adjourn the meeting to another time and place without
further notice other than an announcement at the meeting.

      When a quorum is present at any meeting, a majority of the directors
present shall decide any question brought before such meeting and the act of
such majority shall be the act of the Board.

      Any action required or permitted to be taken by the Board or any Committee
thereof may be taken without a meeting if all members of the Board or Committee
consent in writing to the adoption of a resolution authorizing the action.

      Section 9. Compensation of Directors Directors, as such, shall not receive
any stated salary for their services, but, by resolution of the Board, a fixed
sum and expenses of attendance, if any, may be allowed for attendance at any
meeting of the Board of Directors or of any committee thereof. Nothing herein
contained shall be construed to preclude any director from serving the


                                       10


Corporation in any other capacity and receiving reasonable compensation
therefor.

      Section 10. Committees The Board of Directors, by resolution of a majority
of the entire Board, may designate from among its members one or more
committees, each consisting of three or more directors, and each of which, to
the extent provided in such resolution, shall have all the authority of the
Board except that no such committee shall have authority as to any of the
following matters:

      (a) The submission to stockholders of any action as to which stockholders'
      authorization or approval is required by statute, the Certificate of
      Incorporation or by these By-Laws;

such committee who may replace any absent member or members at any meeting of
such committee.

Directors shall have power at any time to fill


                                       11


vacancies in, to change the membership of, or to discharge any such committee.
Committees shall keep minutes of their proceedings and shall report the same to
the Board of Directors at the meeting of the Board next succeeding, and any
action by the committee shall be subject to revision and alteration by the Board
of Directors, provided that no rights of a third person shall be affected by any
such revision or alteration.

      Section 11. Written Action 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 all members of the Board or committee, as the case may be,
