                     Incorporated under the laws of Delaware


         Section 1. Offices: In addition to its principal or registered office
in this state, the corporation may have offices at such other places within or
without this state as the Board of Directors shall from time to time determine.

         Section 2. Stockholders Meetings: Meetings of the stockholders may be
held at such place or places within or without this state as may be determined
by the Board of Directors, unless otherwise specifically required by law. The
annual meeting of the stockholders for the election of directors shall be held
on such date and at such time as designated by duly adopted resolution of the
Board of Directors or stockholders. Subject to specific requirements of law,
special meetings of the stockholders may be held upon call of the President, any
Vice President, or the Board of Directors. Such call shall state the time, place
and purpose of the meeting. Notice of the time and place of every meeting of
stockholders shall be mailed by the Secretary or the officer performing his
duties, at least ten days before the meeting, to each stockholder of record
having voting power and entitled to such notice at his last known post office
address; provided, however, that if a stockholder be present at a meeting, or in
writing waive notice thereof before or after the meeting, notice of the meeting
to such stockholder shall be unnecessary. The holders of a majority of the
shares of stock having voting power present in person or by proxy shall
constitute a quorum. Each holder of stock shall be entitled at every meeting of
the stockholders to one vote for each share of such stock registered in his name
on the books of the corporation. At all meetings of stockholders, except as
otherwise required by law, by the Certificate of Incorporation, or by other
provisions of these by-laws, all matters shall be decided by the vote of the
holders of a majority of all the stock present or represented at the meeting and
entitled to vote thereat. If required by statute, at least ten days before each
election of directors a complete list of the stockholders entitled to vote at
the election shall be prepared and shall be open at a place within the city
where the election is to be held and shall, during the usual hours of business,
for said ten days, and during the election, be open to the examination of any
stockholder.

         Section 3. Stockholders Consent Action: Any action required or
permitted to be taken by the stockholders at a meeting thereof (including
limitation at the annual meeting) may be taken without a meeting if all the
stockholders consent thereto in writing, and if such written consent action is
filed with the minutes of proceedings of the stockholders. Requirements of law,
of the Certificate of Incorporation, or of these by-laws with respect to notices
of meetings, waivers of such notices, availability of stockholders lists, and
similar requirements, shall be deemed to have

been waived by the stockholders with respect to any such written consent action,
as evidenced by execution of same by each such stockholder.

         Section 4. Board of Directors: The affairs of the corporation shall be
managed by a board consisting of one or more directors, who shall be elected
annually by the stockholders entitled to vote and shall hold office until their
successors are elected and qualified. The authorized number of directors shall
be set from time to time by resolution of the Board of Directors. Any director
may be removed by a majority of the directors at any meeting of the Board of
Directors, for malfeasance, misfeasance, nonfeasance or incapacity or inability
to act. Vacancies in the Board of Directors and newly created directorships
resulting from any increase in the authorized number of directors may be filled
by a majority of the directors remaining in office, even though less than a
quorum, subject to the applicable provisions of laws. Vacancies may also be
filled at any time through election of directors at a special meeting of
stockholders. Meetings of the Board of Directors shall be held at the times
fixed by resolutions of the Board or upon call of the President or any two
directors and may be held outside of this state. The Secretary or officer
performing his duties shall give reasonable notice (which need not in any event
exceed two days) of all meetings of directors, provided that a meeting may be
held without notice immediately after the annual election, and notice need not
be given of regular meetings held at times fixed by resolutions of the Board.
Meetings may be held at any time without notice if all the directors are present
or if those not present waive notice either before or after the meeting. Notice
by mail or telegraph to the usual business or residence address of the directors
not less than the time above specified before the meeting shall be sufficient. A
majority of the directors shall constitute a quorum.

         Section 5. Directors Consent Action: Any action required or permitted
to be taken by the directors at a meeting thereof may be taken without a meeting
if all directors consent thereto in writing, and if such written consent action
is filed with the minutes of proceedings of the directors. Requirements of law,
of the Certificate of Incorporation, of these by-laws with respect to notices of
meetings and waivers thereof shall be deemed to have been complied with upon the
execution of any such written consent action.

         Section 6. Stock: Certificates of stock shall be of such form and
device as the Board of Directors may determine and shall be signed by the
President or any Vice President and the Treasurer or any Assistant Treasurer or
the Secretary or any Assistant Secretary. The stock shall be transferable or
assignable only on the books of the corporation by the holders in person or by
attorney on the surrender of the certificates therefor.

         Section 7. Officers: The Board of Directors shall appoint a President,
one or more Vice Presidents, a Secretary and a Treasurer, and shall from time to
time appoint such other officers as they may deem proper. The term of office of
all officers shall be until their respective successors are chosen and
qualified, but any officer may be removed from office at any time by the Board
of Directors without cause assigned. The officers shall have such duties as
usually pertain to their offices except as modified by the Board of Directors,
and shall also have such powers and duties as may from time to time be conferred
upon them by the Board of Directors.

         Section 8. Fiscal Year: The fiscal year of the corporation shall end on
the Friday nearest September 30.

         Section 9. Corporate Seal: The corporate seal of the corporation shall
be in such form as the Board of Directors shall prescribe.

         Section 10. Amendments: Except as otherwise provided by law either the
Board of Directors or the stockholders may alter or amend these by-laws at any
meeting duly held as above provided.
