                   ------------------------

                   -------------------------

Each director (whether elected at an annual meeting or to fill a vacancy or
otherwise) shall continue in office until his or her successor shall have been
elected and qualified or until his or her earlier death, resignation or removal
in the manner hereinafter provided.

     Section 2.4   Vacancies and Additional Directorships. If any vacancy shall
                   --------------------------------------
occur among the directors by reason of death, resignation or removal, or as the
result of an increase in the number of directorships, a majority of the
directors then in office, or a sole remaining director, though less than a
quorum, may fill any such vacancy.

     Section 2.5   Meetings, Notice of Meetings and Waiver. A meeting of the
                   ---------------------------------------
Board Directors shall be held for organization, for the election of officers and

meeting, within thirty days after each annual election of directors.

     The Board of Directors by resolution may provide for the holding of regular
meetings and may fix the times and places at which such meetings shall be held.
Notice of regular meetings shall not be required to be given, provided that

each director who shall not have been present at the meeting at which such
action was taken, addressed to him or her at his or her residence or usual place
of business.

     Special meetings of the Board of Directors may be called by or at the
direction of any designated officer or any two directors, except that when the
Board of Directors consists of one director then the one director may call a
special meeting. Except as otherwise required by law, notice of each special
meeting shall be mailed to each director, addressed to him or her at his or her
residence or usual place of business, at least three days before the day on

her personally, not later than the second day before the day on which the
meeting is to be held. Such notice shall state the time and place of such
meeting, but need not state the purposes thereof, unless otherwise required by
law, the Certificate of Incorporation of the Corporation or these By-laws.

     Notice of any meeting need not be given to any director who shall attend
such meeting in person or who shall waive notice thereof, before or after such
meeting, in a signed writing, except that attendance shall not constitute waiver
of notice if said director attends solely for the express purpose of objecting,
at the beginning of the meeting, to the transaction of any business because the
meeting is not lawfully called or convened.

     Section 2.6   Quorum and Manner of Acting. At each meeting of the Board of
                   ---------------------------
Directors the presence of a majority of the total number of members of the Board
of Directors as constituted from time to time, but not less than two, shall be
necessary and sufficient to constitute a quorum for the transaction of business,
except that when the Board of Directors consists of only two directors or only
one director, then one director shall constitute a quorum. In the absence of a
quorum, a majority of those present at the time and place of any meeting may
adjourn the meeting from time to time until a quorum shall be present and the
meeting may be held as adjourned without further notice or waiver. A majority of
those present at any meeting at which a quorum is present may decide any
question brought before such meeting, except as otherwise provided by law, the
Certificate of Incorporation of the Corporation or these By-laws. Any member or
members of the Board of Directors or of any committee designated by the Board,
may participate in a meeting of the Board, or any such committee, as the case
may be, by means of conference telephone or similar communications equipment by
means of which all persons participating in the meeting can hear each other. The
Chairman of the Board, if any and if present and acting shall preside at all

acting, or the President, if present and acting, or any other director chosen by

directors as provided in Section 2.3.

                   -------------------------
reasonable compensation for their services as such, whether in the form of

Corporation or a facsimile thereof to be affixed to or reproduced on all such
papers as said committee shall designate. The Board of Directors may designate
one or more directors as alternate members of any committee who, in the order
specified by the Board of Directors, may replace any absent or disqualified
member at any meeting of the committee. If at a meeting of any committee one or
more of the members thereof should be absent or disqualified, and if either the
Board of Directors has not so designated any alternate member or members, or the
number of absent or disqualified members exceeds the number of alternate members
who are present at such meeting, then the member or members of such committee
(including alternates) present at any meeting and not disqualified from voting,
whether or not he or she or they constitute a quorum, may unanimously appoint
another director to act at the meeting in the place of any such absent or
disqualified member. The term of office of the members of each committee shall
be as fixed from time to time by the Board of Directors, subject to these
By-laws; provided, however, that any committee member who ceases to be a member
of the Board of Directors shall likewise cease to be a committee member. Each
committee shall appoint a secretary, who may be the Secretary of the Corporation
or an Assistant Secretary thereof.

     Section 3.2   Meetings, Notices and Records. Each committee may provide for
                   -----------------------------
the holding of regular meetings, with or without notice, and may fix the times
and places at which such meetings shall be held. Special meetings of each
committee may be called by or at the direction of its chairman or, if there be
no chairman, by or at the direction of any one of its members. Except as
otherwise provided by law, notice of each special meeting of a committee shall
be mailed to each member of such committee, addressed to him or her at his or
her residence or usual place of business, at least three days before the day on
which the meeting is to be held, or shall be sent to him or her at such place by
telegram, radio or cable, or telephoned or

                                        5



delivered to him or her personally, not later than the second day before the day
on which the meeting is to be held. Such notice shall state the time and place
of such meeting, but need not state the purposes thereof, unless otherwise
required by law, the Certificate of Incorporation of the Corporation or these
By-laws.

     Notice of any meeting of a committee need not be given to any member
thereof who shall attend such meeting in person or who shall waive notice
thereof, before or after such meeting, in a signed writing except that
attendance shall not constitute waiver of notice if said director attends solely
for the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Each committee shall keep a record of its proceedings.

     Section 3.3   Quorum and Manner of Acting. At each meeting of any committee
                   ---------------------------
the presence of a majority of its members then in office shall be necessary and
sufficient to constitute a quorum for the transaction of business, except that
when a committee consists of one member, then the one member shall constitute a
quorum. In the absence of a quorum, a majority of the members present at the
time and place of any meeting may adjourn the meeting from time to time until a
quorum shall be present and the meeting may be held as adjourned without further
notice or waiver. The act of a majority of the members present at any meeting at
which a quorum is present shall be the act of such committee. Subject to the
foregoing and other provisions of these Bylaws and except as otherwise
determined by the Board of Directors, each committee may make rules for the
conduct of its business. Any member or members of the Committee or of any
committee designated by the Board, may participate in a meeting of the Board, or
any such committee, as the case may be, by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other.

     Section 3.4   Resignations. Any member of a committee may resign at any
                   ------------
time by giving written notice of such resignation to the Board of Directors or
to any designated officer. Unless otherwise specified in such notice, such
resignation shall take effect upon receipt thereof by the Board of Directors or
any such officer, and the acceptance of such resignation shall not be necessary
to make it effective.

     Section 3.5   Removal. Any member of any committee may be removed at any
                   -------
time with or without cause by the Board of Directors.

     Section 3.6   Vacancies. If any vacancy shall occur in any committee by
                   ---------
reason of death, resignation, disqualification, removal or otherwise, the
remaining member or members of such committee, so long as a quorum is present,
may continue to act until such vacancy is filled by the Board of Directors.

     Section 3.7   Compensation. Committee members may receive such reasonable
                   ------------
compensation for their services as such, whether in the form of salary or a
fixed fee for attendance at meetings, with expenses, if any, as the Board of
Directors may from time to time determine. Nothing herein contained shall be
construed to preclude any committee member from serving the Corporation in any
other capacity and receiving compensation therefor.
