                                  STOCKHOLDERS

     Section 1. Annual Meetings. The annual meetings of the stockholders of the
Corporation for the election of Directors and the transaction of such other
business as may properly come before such meeting shall be held at the principal
office of the Corporation, at 1:00 PM local time on the 3rd Tuesday in April
         (or, if such day is a legal holiday, then on the next succeeding
business day) or at such other place (within or without the State of Delaware)
or such other date and hour, as may be fixed from time to time by the Board of
Directors and set forth in the Notice or waiver of notice of such meeting.
[(Sections 211(a), (b)]*

     Section 2. Special Meetings. Special meetings of the stockholders may be
called at any time by the Chairman or the President (or, in their absence or
disability, by any Vice President), or by the Board of Directors. A special
meeting shall be called by the Chairman or the President (or, in their absence
or disability, by any Vice President), or by the Secretary, immediately upon
receipt of a written request by stockholders holding in the aggregate not less
than 10% of the outstanding shares of the Corporation at the time entitled to
vote at any meeting of the stockholders. If such officers shall fail to call
such meeting within 20 days after receipt of such request, any stockholder

     Section 3. Notice of Meetings; Waiver. The Secretary or any Assistant
Secretary shall cause written notice of the place, date and hour of each
meeting of the stockholders, and, in the case of a special meeting, the purpose
or purposes for which such meeting is called, to be given personally or by mail,
not less than ten nor more than sixty days before the date of such meeting, to
each stockholder of record entitled to vote at such meeting. Such further notice
shall be given as may be required by law.

     If such notice is mailed, it shall be deemed to have been given to a
stockholder when deposited in the United States mail, postage prepaid, directed
to the stockholder at his address as it appears on the record of stockholders of
the Corporation, or, if he shall have filed with the Secretary of the
Corporation a written request that notices to him be mailed to some other
address, then directed to him at such other address.

     No notice of any meeting of stockholders need be given to any stockholder
who submits a signed waiver of notice, whether before or after such meeting.
Neither the business to be transacted at, nor the purpose of, any regular or
special meeting of the stockholders need the specified in any written waiver of
notice. The attendance of any stockholder at a meeting of stockholders shall
constitute a waiver of notice of such meeting, except when the stockholder
attends a meeting for the express purpose for objecting, at the beginning of the
meeting, to the transaction of any business on the ground that the meeting is
not lawfully called or convened.

     Except as set forth in Section 1.07 of these By-Laws, notice of any
adjourned meeting of the stockholders of the Corporation need not be given.
[Sections 222, 229]

     Section 4. Quorum. Except as otherwise required by law or by the
Certificate of Incorporation, the presence in person or by proxy of the holders
of record of a majority of the shares of stock entitled to vote at any meeting
shall constitute a quorum for the transaction of business at such meeting. When
a quorum is once present to organize a meeting, it is not broken by the
subsequent withdrawal of any stockholders.

                                      - 2 -







     Section 5. Voting. Every holder of record of shares entitled to vote at a
meeting of stockholders shall be entitled to one vote for each share standing in
his name on the books of the Corporation on the record date fixed pursuant to
Section 5.06 of these By-Laws. Except as otherwise required by law or by the
Certificate of Incorporation, the vote of a majority of the shares represented
at any meeting of which a quorum is present shall be sufficient for the
transaction of any business at such meeting. [Section 216]


     Section 6. Voting by Ballot. No vote of the stockholders need be taken by
written ballot, unless otherwise required by statute. Any vote which need not be
taken by ballot may be conducted in any manner approved by the meeting.

     Section 7. Adjournment. If a quorum is not present at any meeting of the
stockholders, the stockholders present in person or by proxy shall have the
power to adjourn any such meeting from time to time until a quorum is present,
without notice other than announcement at any such meeting of the place, date
and hour to which such meeting is adjourned. However, if the adjournment is for
more than thirty days, or if after the adjournment the Board of Directors fixes
a new record date for the adjourned meeting pursuant to Section 5.06 of these
By-Laws, a notice of the adjourned meeting, conforming to the requirements of
Section 1.63 hereof, shall be given to each stockholder of record entitled to
vote at such meeting. At any adjourned meeting at which a quorum is present, any
business may be transacted that might have been transacted on the original date
of the meeting. [Section 222(a)]

     Section 8. Proxies. Any stockholder entitled to vote at any meeting of the
stockholders or to express consent to or dissent from corporate action without a
meeting may, by a written instrument signed by such stockholder or his
attorney-in-fact, authorize another person or persons to vote at any such
meeting and express such consent or dissent for him by proxy. No such proxy
shall be voted or acted upon after the expiration of three years from the date
of such proxy, unless such proxy provides for a longer period. Every proxy shall
be revocable at the pleasure of the stockholder executing it, except in those
cases where applicable law provides that a proxy shall be irrevocable. [Section
212(b),(c)]

     Section 9. Organization; Procedure. At every meeting of stockholders the
presiding officer shall be the Chairman or in his absence the President, or in
their absence a Vice President designated by the Board of Directors, or in the
absence of such officers, a presiding officer chosen by a majority of the
stockholders present in person or by proxy. The Secretary or, in his absence, an
Assistant Secretary or, in his absence, an appointee of the presiding officer
shall act as Secretary of the meeting. The order of business and all other
matters of procedure at every meeting of stockholders may be determined by such
presiding officer.

     Section 10. Inspectors of Election. In advance of any meeting of
stockholders, the Board of Directors may appoint one or more Inspectors to act
at such meeting or any adjournment thereof. If Inspectors are not so appointed,
the person presiding at such meeting may, and on the request of any stockholder
entitled to vote at such meeting shall, appoint one or more Inspectors. In the
event any person so appointed fails to appear or act, such vacancy may be filled
by the Board in advance of such meeting or at such meeting by the person
presiding thereat. Each Inspector, before entering upon the discharge of his
duties, 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. At any meeting of stockholders for which Inspectors shall have
been appointed, such Inspectors shall determine the number of shares outstanding
and the voting power of each, the shares represented at the meeting, the
existence of a quorum and the validity and effect of proxies, and shall receive
votes, ballots or consents, hear and determine all challenges and questions
arising in connection with the right to vote, count and tabulate all votes,
ballots or consents, determine the result, and do such acts as are proper to
conduct the election or vote with fairness to all shareholders. On request of
the person presiding at the meeting or any stockholder entitled to vote thereat,
the Inspectors shall make a report in writing of any challenge, question or
matter determined by them and execute a certificate of any fact found by them,
any report or certificate made by them shall be prima facie evidence of the
facts stated and of the vote as certified by them.

                                      - 4 -







     Section 11. Consent of Stockholders in Lieu of Meeting. Whenever the vote
of stockholders at a meeting thereof is required or permitted to be taken for
or in connection with any corporate action, by law, by the Certificate of
Incorporation or by these By-Laws, the meeting and vote of stockholders may be
dispensed with if all of the stockholders who would have been entitled to vote
upon the action if such meeting were held shall consent in writing to such
corporate action being taken. [Section 228]

a special meeting is to be held, notice of the meeting stating the time and
place thereof shall be mailed, or sent by telegram, radio or cable to each
Director, addressed to him at his usual place of business, or delivered to him
personally. Notice of any special meeting need not be given to any Director who
attends such meeting without protesting the lack of notice to him, prior to or

waiver of notice, whether before or after such meeting, and any business may be

presence of a majority of the total number of Directors (but in no event less
than one-third of the total number of Directors) shall constitute a quorum for

majority of the directors present at any meeting at which a quorum is present

     Section 7. Adjournment. A majority  of the Directors present, whether or
not a quorum is presents may adjourn any meeting to another time and place.
Notice of the adjourned meeting shall be given to the extent required by

with the minutes of proceedings of the Board or such Committee. [Section 141(f)]

     Section 9. Regulations; Manner of Acting. To the extent consistent with
law, the Certificate of Incorporation and these By-Laws, the Board of Directors

vacancy in the Board, caused by any removal of a Director by vote of the
stockholders, may he filled by  the stockholders entitled to vote for the
election of the Director so removed. If such stockholders do not fill such
vacancy at the meeting at which such removal was effected (or in the written
instrument effecting such removal, if such removal was effected by consent
without a meeting) such vacancy may be filled in the manner provided in Section
2.13 hereof. [Section 141(b)]

     Section 13. Vacancies and Newly Created Directorships. Subject to the

Director without cause) may be filled by vote of a majority  of the Directors
then in office, although less than a quorum exists. A Director elected to fill
a vacancy  shall be elected to hold office for the unexpired term of his
predecessor. Any such newly created Directorship and any such vacancy may also
be filled at any time by vote of the stockholders.

     Section 14. Compensation. The amount, if any, which each Director shall be
entitled to receive as compensation for his services as such shall be fixed from
time to time by the Board of Directors.

                    EXECUTIVE COMMITTEE AND OTHER COMMITTEES

     Section 1. How Constituted. The Board of Directors, by resolution or
resolutions adopted by a majority of the whole Board, may designate from among
the Directors an Executive Committee and/or one or more other Committees, each

from time to time may be fixed by resolution or resolutions similarly adopted.
The Board, by resolution or resolutions similarly adopted, may designate one or
more Directors as alternate members of any such Committee, who may replace any
absent or disqualified member or members at any meeting of such Committee.
Thereafter members (and alternate members, if any) of each such Committee may be
designated annually, by resolution similarly adopted at the meeting of the Board
of Directors immediately following the annual meeting of stockholders. Any such
