by a majority of the directors then in office, though less than a quorum, or by
a sole remaining director, and the directors so chosen shall hold office until
the next annual election and until their successors are duly elected and
qualified, or until their earlier resignation or removal.

                                  ARTICLE VII.

         In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to adopt, amend or
repeal the bylaws of the Corporation.

                                 ARTICLE VIII.

         The Corporation shall indemnify, to the fullest extent authorized or
permitted by law, as the same exists or may hereafter be amended, any person who
was or is made or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation), by
reason of the fact that such person is or was a director or officer of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of any other company, partnership, limited
liability company, joint venture, trust, employee benefit plan or other
enterprise; provided, however, that the Corporation shall not indemnify any
director or officer in connection with any action by such director or officer
against the Corporation unless the Corporation shall have consented to such
action. The Corporation may, to the extent authorized from time to time by the
Board of Directors, provide rights to indemnification to employees and agents of
the Corporation similar to those conferred in this Article IX to directors and
officers of the Corporation. No amendment or repeal of this Article IX shall
apply to or have any effect on any right to indemnification provided hereunder
with respect to any acts or omission occurring prior to such amendment or
repeal.

                                  ARTICLE IX.

         No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for any breach of fiduciary
duty by such a director as a director, except to the extent provided by
applicable law (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 General Corporation Law of Delaware, or (iv) for
any transaction from which such director derived an improper personal benefit.
If the General Corporation Law of Delaware is amended to authorize corporate
action further eliminating or limiting the personal liability of directors, then
the liability of a director of the Corporation shall be eliminated or limited to
the fullest extent permitted by the General Corporation Law of Delaware as so
amended. No amendment to or repeal of this Article X shall apply to or have any
effect on the liability or alleged liability of any director of the Corporation
for or with respect to any acts or omissions of such director occurring prior to
such amendment or repeal.

                                   ARTICLE X.

         The Corporation reserves the right to amend, alter, change, or repeal
any provisions 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.
