Corporation as a director, officer, employee, agent, partner or trustee (or in
any similar position) of another corporation, partnership, joint venture, trust
, employee benefit plan or other enterprise, to the fullest extent authorized or
permitted by the General Corporation Law of the State of Delaware and any other
applicable law, as the same exists or may hereafter be amended (but, in the case
of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than said law permitted
the Corporation to provide prior to such amendment), against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or her in connection with such action, suit or
proceeding, or in connection with any appeal thereof, provided however, that,
except as provided in Section C of this Article NINTH with respect to
proceedings to enforce rights to indemnification, the Corporation shall
indemnify any such person in connection with an action, suit or proceeding (or
part thereof) initiated by such person only if the initiation of such action,
suit or proceeding (or part thereof) was authorized by the Board of Directors.
Such right to indemnification shall include the right to payment by the
Corporation of expenses incurred in connection with any such action, suit or
proceeding in advance of its final disposition; provided, however that the
payment of such expenses incurred by a director or officer in advance of the
final disposition of such action, suit or proceeding shall be made only upon
delivery to the Corporation of an undertaking, by or on behalf of such director
or officer, to repay all amounts so advanced if it should be determined
ultimately that such director or officer is not entitled to be indemnified under
this Article or otherwise.

                  C. Any indemnification or advancement of expenses required
under this Article shall be made promptly, and in any event within sixty (60)
days, upon the written request of the person entitled thereto. If a
determination by the Corporation that the person is entitled to indemnification
pursuant to this Article is required, and the Corporation fails to respond
within sixty (60) days to a written request for indemnity or advancement of
expenses, in whole or in part, or if payment in full pursuant to such request is
not made within sixty (60) days, the rights to indemnification and advancement
of expenses shall be enforceable by such person in any court of competent
jurisdiction. Such person's costs and expenses incurred in connection with
successfully establishing his or her right to indemnification, in whole or in
part, in any such action or proceeding shall also be indemnified by the
Corporation. It shall be a defense to any such action other than an action
brought to enforce a claim for advancement of expenses pursuant to this Article
where the required undertaking has been received by the Corporation) that the
claimant has not met the standard of conduct set forth in the General
Corporation Law of the State of Delaware, but the burden of proving such defense
shall be on the Corporation. Neither the failure, of the Corporation (including
the Board of Directors, independent legal counsel or the stockholders) to have
made a determination of the claimant is proper in the circumstances because he
or she has met the applicable standard of conduct set forth in the General
Corporation Law of the State of Delaware, nor the fact that there has been an
actual determination by the Corporation (including the Board of Directors,
independent legal counsel or the stockholders) that the claimant has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that the claimant has not met the applicable standard of conduct.



                                        4




                  D. The indemnification and advancement of expenses provided
by, or granted pursuant to, this Article shall not be deemed exclusive of any
other rights to which those seeking indemnification or advancement of expenses
may be entitled under by-law, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his or her official capacity and as
to action in another capacity while holding such office, and shall continue as
to a person who has ceased to be a director, officer, employee or agent, and
shall inure to the benefit of the heirs, executors and administrators of such a
person. Any repeal or modification of the provisions of this Article NINTH shall
not affect any obligations of the Corporation or any rights regarding
indemnification and advancement of expenses of a director, officer, employee or
agent with respect to any threatened, pending or completed action, suit or
proceeding for which indemnification or the advancement of expenses is
requested, in which the alleged cause of action accrued at any time prior to
such repeal or modification.

                  E. The Corporation may purchase and maintain insurance, at its
expense. to protect itself and any person who is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise
against liability asserted against him or her in any such capacity, or arising
out of his or her status as such, whether or not the Corporation would have the
power to indemnify him or her against such liability under the provisions of
this Article, the General Corporation Law of the State of Delaware or otherwise.

                  F. If this Article NINTH or any portion thereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each director and officer of the
Corporation as to expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement with respect to any action, suit or proceeding,
whether civil, criminal, administrative or investigative, including, without
limitation, a grand jury proceeding and an action, suit or proceeding by or in
the right of the Corporation, to the fullest extent permitted by any applicable
portion of this Article that shall not have been invalidated, by the General
Corporation Law of the State of Delaware or by any other applicable law.
