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

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

         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         have been adopted, amended, or repealed, as the case may be, in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 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 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 subsection (d) of Section
         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 Section 242 of the General
         Corporation Law of the State of Delaware shall otherwise require;
         provided, that no share of any such class

                                      -2-


         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 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 Section 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 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 Bylaw, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in such person's 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
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.
