          SIXTH: The corporation is to have perpetual existence.

          SEVENTH: Whenever a compromise or arrangement is proposed 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
the provisions of (S)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 the provisions of (S)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 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 this corporation, as the case may be, and also on this
corporation.

          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

                                       7



          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 (S)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 provisions for the
          classification of directors of the corporation for staggered terms
          pursuant to the provisions of subsection (d) of (S)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.

               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 (S)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 or decrease in the number of authorized shares of said class.

                                       8



          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 (S)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 (S)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.
