                                       2



class of stockholders of this Corporation, as the case may be, to be summoned in
such manner as the court directs. If a majority and number representing

         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 this Certificate of Incorporation shall entitle the holder thereof
to the right to vote at any meeting of stockholders, except as otherwise
provided by applicable law; 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 clause (b)
of Section 102 of the Delaware General Corporation Law, as the same may be
amended or supplemented. The provisions of this Article Ninth are not intended
to, and shall not, limit, supersede or modify any other defense available to a
director under applicable law. Any repeal or modification of this Article Ninth
by the stockholders of the Corporation shall not adversely affect any right or
protection of a director of the Corporation existing at the time of such repeal
or modification.

         TENTH:

         1.       The Corporation shall, to the fullest extent permitted by
Section 145 of the Delaware General Corporation Law, as the same may be amended
or supplemented (but in the case of any such amendment or supplement, only to
the extent that such amendment or supplement permits the Corporation to provide
broader indemnification

                                        3



rights than said law permitted the Corporation to provide prior to such
amendment or supplement), indemnify any and all directors and officers 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 continue as to a
person who has ceased to be a director or officer and shall inure to the benefit
of the heirs, executors and administrators of such person. The Corporation may,
in its sole discretion and to the fullest extent permitted by Section 145 of the
Delaware General Corporation Law, as the same may be amended or supplemented,
indemnify any and all employees and agents 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 continue as to a person who has ceased to be an
employee or agent and shall inure to the benefit of the heirs, executors, and
administrators of such person.

         2.       The Corporation shall pay the expenses incurred in defending
any proceeding against a director or officer which is or may be subject to
indemnification pursuant to this Article Tenth in advance of final disposition
of such proceeding; provided, however, that the payment of such expenses
incurred by a director or officer shall be made only upon receipt of an
undertaking by the director or officer to repay all amounts advanced if it
should be ultimately determined that the director or officer is not entitled to
be indemnified under this Article Tenth or otherwise. The Corporation may, in
its sole discretion, advance expenses incurred by its employees or agents to the
same extent as expenses may be advanced to its directors and officers hereunder.

         3.       The rights conferred on any person by this Article Tenth shall
be deemed contract rights and shall not be exclusive of any other rights which
such person may have or hereafter acquire under any statute, provision of this
Certificate of Incorporation or the Corporation's Bylaws, agreement, or vote of
stockholders or disinterested directors or otherwise.

         4.       The Corporation may purchase and maintain insurance to protect
itself and any other director, officer, employee or agent of the Corporation or
any corporation, partnership, joint venture, trust or other enterprise against
any liability, whether or not the Corporation would have the power to indemnify
such person under the Delaware General Corporation Law.

         ELEVENTH:

         1.       From time to time any of the provisions of this Certificate of
Incorporation may be amended, altered or repealed in accordance with the laws of
the State of Delaware.

by an affirmative vote of at least a majority of either (i) the shares of the
Corporation's capital stock entitled to vote thereon, or (ii) the Board of
Directors.
