application of any receiver or receivers appointed for this corporation 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 this corporation 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 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:

         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 By-Laws.
         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.

                                                                               9


                  2. After the original or other By-Laws of the corporation have
         been adopted, amended, or repealed, as the case may be, in accordance
         with the provisions of Section 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
         By-Laws 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 subsection (d) of Section 141 of the
         General Corporation Law of the State of Delaware shall be set forth in
         an initial By-Law or in a By-Law 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 (c)(2) of section 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.

         NINTH: The corporation shall, to the fullest extent permitted by
Section 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 By-Law, agreement, vote of
   10
                                                                              10


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.

         TENTH: 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 TENTH.
