FIFTH: In furtherance and not in limitation of the powers conferred by statute,
the board of directors is expressly authorized to make, alter or repeal the
by-laws of the Company. In addition, to the powers and authorities hereinbefore
or by statute expressly conferred upon them, the directors are hereby empowered
to exercise all such powers and do all such acts and things as may be exercised
or done by the corporation; subject, nevertheless, to the provisions of the
statutes of Delaware, of this certificate, and to any by-laws from time to time
made by the stockholders; provided, however, that no by-law so made shall
invalidate any prior act of the directors which would have been valid if such
by-law had not been made.

SIXTH: Whenever a compromise or arrangement is proposed between the Company and
its creditors or any class of them and/or between the Company and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of the Company or
of any creditor or stockholder thereof, or on the application of any receiver or
receivers appointed for the Company under the provisions of Section 291 of Title
8 of the Delaware Code or on the application of trustees in dissolution or of
any receiver or receivers appointed for the Company under the provisions of
Section 279 of Title 8 of the Delaware Code, order a meeting of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of the
Company, as the case may be, to be summoned in such manner as the said court
directs. If a majority in number representing three-fourths in value of the
creditors or class of creditors, and/or of the stockholders or class of
stockholders of the Company, as the case may be, agrees to any compromise or
arrangement and to any reorganization of the Company as a consequence of such
compromise or arrangement, the said compromise or arrangement and the said
reorganization shall, if sanctioned by the court to which the said application
has been made, be binding on all the creditors or class of creditors, and/or on
all the stockholders or class of stockholders of the Company, as the case may
be, and also on the Company.

SEVENTH: Meetings of stockholders may be held outside the State of Delaware, if
the by-laws so provide. The books of the corporation may be kept (subject to any
provision contained in the statutes) outside the State of Delaware at such place
or places as may be designated from time to time by the Board of Directors or in
the by-laws of the corporation. Elections of directors need not be by ballot
unless the by-laws of the corporation shall so provide.

EIGHTH: The Company shall, to the fullest extent permitted by the General
Corporation Law of the State of Delaware, indemnify any and all persons whom it
shall have power to indemnify from and against any and all expenses, liabilities
or other matters.

              Name:                              Mailing Address:
              ----                               ---------------

              Michael J. Fuchs                   430 Park Avenue
                                                 New York, New York 10022



TENTH: To the fullest extent permitted by the Delaware General Corporation Law
now in effect and as amended from time to time, a director of the Corporation
shall not be liable to the Corporation or its stockholders for monetary damages
for breach of fiduciary duty resulting from actions or omissions while serving
as a director.

ELEVENTH: The number of directors which shall constitute the whole Board of
Directors shall be not less than three (3) and shall be fixed from time to time
exclusively by the Board of Directors pursuant to a resolution adopted by a
majority of the total number of authorized directors (whether or not there exist
any vacancies in the previously authorized directorships at the time any such
resolution is presented to the Board of Directors for adoption). At the Annual
Meeting of Stockholders at which this Article is adopted, the directors shall be
divided into three classes, designated Class I, Class II, and Class III (which
at all times shall be as nearly equal in number as possible), with the term of
office of Class III directors to expire at the 1999 Annual Meeting of
Stockholders, the term of office of Class II directors to expire at the 2000
Annual Meeting of Stockholders, and the term of office of Class I directors to
expire at the 2001 Annual Meeting of Stockholders. At each annual meeting of
stockholders following such initial classification and election, directors
elected to succeed those directors whose terms expire shall be elected for a
term of office to expire at the third succeeding annual meeting of stockholders
after their election. Subject to the rights of the holders of any class or
series of the Voting Stock then outstanding, newly created directorships
resulting from any increase in the authorized number of directors or any
vacancies on the Board of Directors resulting from death, resignation,
retirement, disqualification, removal from office or other cause may be filled
by a majority vote of the directors then in office, though less than a quorum,
and directors so chosen shall hold office for a term expiring at the annual
meeting of stockholders at which the term of office of the class to which they
have been elected expires. No decrease in the number of authorized directors
constituting the entire Board of Directors shall shorten the term of any
incumbent director.
