        The Board of Directors is authorized, subject to any limitations
prescribed by the law of the State of Delaware, to provide for the issuance of

each such series, to fix the designation, powers, preferences and rights of the
shares of each such series and any qualifications, limitations or restrictions
thereof, and to increase or decrease the number of shares of any such series
(but not below the number of shares of such series then outstanding). The number
of authorized shares of Preferred Stock may be increased or decreased (but not
below the number of shares thereof then outstanding) by the affirmative vote of
the holders of a majority of the stock of the corporation entitled to vote,
unless a vote of any other holders is required pursuant to a certificate or
certificates establishing a series of Preferred Stock.

        Except as otherwise expressly provided in any certificate of designation
designating any series of Preferred Stock pursuant to the foregoing provisions
of this Article IV, any new series of Preferred Stock may be designated, fixed
and determined as provided herein by the Board of

Directors without approval of the holders of Common Stock or the holders of
Preferred Stock, or any series thereof, and any such new series may have powers,
preferences and rights, including, without limitation, voting rights, dividend
rights, liquidation rights, redemption rights and conversion rights, senior to,
junior to or pari passu with the rights of the Common Stock, the Preferred
Stock, or any future class or series of Preferred Stock or Common Stock.

                                    ARTICLE V

        The stockholders of the corporation shall have the power to adopt, amend
or repeal Bylaws of the corporation. The Board of Directors of the corporation
shall also have the power to adopt, amend or repeal Bylaws of the corporation,
except insofar as Bylaws adopted by the stockholders shall otherwise provide.

                                   ARTICLE VI

        Election of directors need not be by written ballot unless the Bylaws of
the corporation shall so provide.

        A director of the corporation shall not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the Delaware General Corporation
Law or (iv) for any transaction from which the director derived an improper
personal benefit.

        If the Delaware General Corporation Law is hereafter amended to
authorize the further elimination or limitation of the liability of a director,
then the liability of a director of the corporation shall be eliminated or
limited to the fullest extent permitted by the Delaware General Corporation Law,
as so amended.

        Neither any amendment nor repeal of this Article VII, nor the adoption
of any provision of this Certificate of Incorporation inconsistent with this
Article VII, shall eliminate, reduce or otherwise adversely affect any
limitation on the personal liability of a director of the corporation existing
at the time of such amendment, repeal or adoption of such an inconsistent
provision.
