         EIGHTH: Meetings of stockholders may be held within or outside of the
State of Delaware, as the Bylaws of the Corporation may provide. The books of
the Corporation may be kept outside the State of Delaware at such place or
places as may be designated from time to time by the Board of Directors of the
Corporation or in the Bylaws of the Corporation. Election of directors need not
be by written ballot unless the Bylaws of the Corporation so provide.



         NINTH: No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of his fiduciary
duty as a director; provided, however, that this provision shall not eliminate
or limit the liability of a director (1) for any breach of the director's duty
of loyalty to the Corporation or its stockholders, (2) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (3) under Section 174 of the General Corporation Law of the State of
Delaware, or (4) for any transaction from which the director derived an improper
personal benefit.

         TENTH: The Corporation shall indemnify, in accordance with and to the
full extent now or hereafter permitted by law, any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (including, but not limited to, an action by or in the right of
the Corporation), by reason of such person acting as a director or officer of
the Corporation (and the Corporation, in the discretion of the Board of
Directors, may so indemnify a person by reason of the fact that such person is
or was an employee of the Corporation or is or was serving at the request of the
Corporation in any other capacity for or on behalf of the Corporation) against
any liability or expense actually and reasonably incurred by such person in
respect thereof. Such indemnification is not exclusive of any other right to
indemnification provided by law or otherwise. Expenses incurred by an officer or
director in defending a civil or criminal action, suit or proceeding shall be
paid by the Corporation in advance of the final disposition of such action,
suit, or proceeding upon receipt of an undertaking by or on behalf of such
officer or director to repay such amount if it shall ultimately be determined
that such officer or director is not entitled to be indemnified. The right to
indemnification and advancement of expenses on the condition specified herein
conferred by this Article shall be deemed to be a contract between the
Corporation and each person referred to herein.

         ELEVENTH: No amendment to or repeal of Article NINTH or TENTH of this
Certificate of Incorporation shall apply to or have any effect on the rights of
any individual referred to in Article NINTH or TENTH for or with respect to acts
or omissions of such individual occurring prior to such amendment or repeal.

         IN WITNESS WHEREOF, the undersigned, being the incorporator hereinabove
named, has caused this Certificate of Incorporation to be signed on October 18,
2001.
