            SIXTH: The following provisions are inserted for the management of
the business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

      1.    The business and affairs of the Corporation shall be managed by or
            under the direction of the Board of Directors.

      2.    The directors shall have concurrent power with the stockholders to
            make, alter, amend, change, add to or repeal the Bylaws of the
            Corporation.

      3.    The number of directors of the Corporation shall be as from time to
            time fixed by, or in the



            manner provided in, the Bylaws of the Corporation. Election of
            directors need not be by written ballot unless the Bylaws so
            provide.

      4.    No director shall be personally liable to the Corporation or any of
            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) pursuant
            to Section 174 of the GCL or (iv) for any transaction from which the
            director derived an improper personal benefit. Any repeal or
            modification of this Article Sixth by the stockholders or 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 with respect to acts or omissions occurring prior to
            such repeal or modification.

      5.    In addition to the powers and authority hereinbefore or by statute
            expressly conferred upon them, the directors are hereby empowered to
            exercise all such powers and do all such acts and things as may be
            exercised or done by the Corporation, subject, nevertheless, to the
            provisions of the GCL, this Certificate of Incorporation, and any
            Bylaws adopted by the stockholders; provided, however, that no
            Bylaws hereafter adopted by the stockholders shall invalidate any
            prior act of the directors which would have been valid if such
            Bylaws had not been adopted.

            SEVENTH: The Corporation shall indemnify its directors and officers
to the fullest extent authorized or permitted by law, as now or hereafter in
effect, and such right to indemnification shall continue as to a person who has
ceased to be a director or officer of the Corporation and shall inure to the
benefit of his or her heirs, executors and personal and legal representatives;
provided, however, that, except for proceedings to enforce rights to
indemnification, the Corporation shall not be obligated to indemnify any
director or officer (or his or her heirs, executors or personal or legal
representatives) in connection with a proceeding (or part thereof) initiated by
such person unless such proceeding (or part thereof) was authorized or consented
to by the Board of Directors. The right to indemnification conferred by this
Article Seventh shall include the right to be paid by the Corporation the
expenses incurred in defending or otherwise participating in any proceeding in
advance of its final disposition.

            The Corporation may, to the extent authorized from time to time by
the Board of Directors, provide rights to indemnification and to the advancement
of expenses to employees and agents of the Corporation similar to those
conferred in this Article Seventh to directors and officers of the Corporation.

            The rights to indemnification and to the advance of expenses
conferred in this Article Seventh shall not be exclusive of any other right
which any person may have or hereafter acquire wider this Certificate of
Incorporation, the Bylaws of the Corporation, any statute, agreement, vote of
stockholders or disinterested directors or otherwise.

            Any repeal or modification of this Article Seventh by the
stockholders of the Corporation shall not adversely affect any rights to
indemnification and to the advancement of expenses of a director or officer of
the Corporation existing at the time of such repeal or modification with



respect to any acts or omissions occurring prior to such repeal or modification.

            EIGHTH: Meetings of stockholders may be held within or without the
State of Delaware, as the Bylaws may provide. The books of the Corporation may
be kept (subject to any provision contained in the GCL) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the Bylaws of the Corporation.

            NINTH: The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

            I, the undersigned, being the Sole Incorporator hereinbefore named,
for the purpose of forming a corporation pursuant to the GCL, do make this
Certificate, hereby declaring and certifying that this is my act and deed and
the facts herein stated are true, and accordingly have hereunto set my hand this
