                                            New York, NY  10022






                  SIXTH:  The corporation is to have perpetual existence.

                  SEVENTH: Whenever a compromise or arrangement is proposed
between this corporation and its creditors or any class of them and/or between
this corporation 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 this corporation or of any creditor or stockholder thereof or
on the application of any receiver or receivers appointed for this corporation
under ss. 291 of Title 8 of the Delaware Code or on the application of trustees
in dissolution or of any receiver or receivers appointed for this corporation
under ss. 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
this corporation, 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 this corporation, as the case may be, agree to any compromise
or arrangement and to any reorganization of this corporation as consequence of
such compromise or arrangement, the said compromise or arrangement and the said

                  EIGHTH: For the management of the business and for the
conduct of the affairs of the corporation, and in further definition,
limitation, and regulation of the powers of the corporation and of its
directors and of its stockholders or any class thereof, as the case may be, it
is further provided:

                  1. The management of the business and the conduct of the
                  affairs of the corporation shall be vested in its Board of
                  Directors. The number of directors, which shall constitute
                  the whole Board of Directors shall be fixed by, or in the
                  manner provided in the Bylaws. The phrase "whole Board" and
                  the phrase "total number of directors" shall be deemed to
                  have the same meaning, to wit, the total number of directors
                  which the corporation would have if there were no vacancies.
                  No election of directors need be by written ballot.

                  2. After the original or other Bylaws of the corporation have
                  been adopted, amended, or repealed, as the case may be, in
                  accordance with the provisions of ss.109 of the General
                  Corporation Law of the State of Delaware, and, after the
                  corporation has received any payment for any of its stock,
                  the power to adopt, amend, or repeal the Bylaws of the
                  corporation may be exercised by the Board of Directors of the
                  corporation; provided, however, that any provision for the
                  classification of directors of the corporation for staggered
                  terms pursuant to the provisions of subsections (d) of ss.141
                  of the General Corporation Law of the State of Delaware shall
                  be set forth in an initial Bylaw or in a Bylaw adopted by the
                  stockholders entitled to vote of the corporation unless
                  provisions for such classification shall be set forth in this
                  certificate of incorporation.

                                     - 2 -




                  3. Whenever the corporation shall be authorized to issue only
                  one class of stock, each outstanding share shall entitle the
                  holder thereof to notice of, and the right to vote at, any
                  meeting of stockholders. Whenever the corporation shall be
                  authorized to issue more than one class of stock, no
                  outstanding share of any class of stock which is denied
                  voting power under the provisions of the certificate of
                  incorporation shall entitle the holder thereof to the right
                  to vote at any meeting of stockholders except as the
                  provisions of paragraph (2) of subsection (b) of ss.242 of
                  the General Corporation Law of the State of Delaware shall
                  otherwise require; provided, that no share of any such class
                  which is otherwise denied voting power shall entitle the
                  holder thereof to vote upon the increase to decrease in the
                  number of authorized shares of said class.

                  NINTH: The personal liability of the directors of the
corporation is hereby eliminated to the fullest extent permitted by the
provisions of paragraph (7) of subsection (b) of ss.102 of the General
Corporation Law of the State of Delaware, as the same may be amended and
supplemented.

                  TENTH: The corporation shall, to the fullest extent permitted
by the provisions of ss.145 of the General Corporation Law of the State of
Delaware, as the same may be amended and supplemented, indemnify any and all
persons whom it shall have power to indemnify under said section from and
against any and all of the expenses, liabilities, or other matters referred to
in or covered by said section, and the indemnification provided for herein
shall not be deemed exclusive of any other rights to which those indemnified
may be entitled under any Bylaw, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office, and
shall continue as to a person who has ceased to be a director, officer,
employee, or agent and shall inure to the benefit of the heirs, executors, and
administrators of such a person.

                  ELEVENTH: From time to time any of the provisions of this
certificate of incorporation may be amended, altered, or repealed, and other
provisions authorized by the laws of the State of Delaware at the time in force
may be added or inserted in the manner and at the time prescribed by said laws,
and all rights at any time conferred upon the stockholders of the corporation
by this certificate of incorporation are granted subject to the provisions of
this Article ELEVENTH.
