         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 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.
No election of directors need be by written ballot.

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 (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
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 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
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 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
