Company or its stockholders for monetary damages for breach of fiduciary duty as

law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv)

of a Director of the Company shall be eliminated or limited to the fullest
extent permitted by the Delaware General Corporation Law, as so amended.

      Any repeal or modification of the foregoing paragraph by the stockholders

of the Company existing at the time of such repeal or modification.

      Article 9.

      a) Each person who was or is made a party or is threatened to be made a
party to or is otherwise involved in any action, suit or proceeding, whether
civil, criminal, administrative or investigative (hereinafter a "proceeding"),
by reason of the fact that he or she is or was a Director, officer, employee or
agent of the Company or is or was serving at the request of the Company as a
Director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to an
employee benefit plan (hereinafter an "indemnitee"), whether the basis of such
proceeding is alleged action in an official capacity as a Director, officer,
employee or agent or in any other capacity where serving as a Director, officer,
employee or agent, shall be indemnified and held harmless by the Company to the
fullest extent authorized by the Delaware General Corporation 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 Company to provide broader
indemnification rights than permitted prior thereto), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith and such indemnification
shall continue as to an indemnitee who has ceased to be a Director, officer,
employee or agent and shall inure to the benefit of the indemnitee's heirs,
executors and administrators; provided, however, that, except as provided in
paragraph (b) hereof with respect to proceedings to enforce rights to
indemnification, the Company shall indemnify any such indemnitee in connection
with a proceeding


                                       3


(or part thereof) initiated by such indemnitee only if such proceeding (or part
thereof) was authorized by the Board of Directors of the Company. The right to
indemnification conferred in this Article shall be a contract right and shall
include the right to be paid by the Company the expenses incurred in defending
any such proceeding in advance of its final disposition (hereinafter an
"advancement of expenses"); provided, however, that, if the Delaware General
Corporation Law requires, an advancement of expenses incurred by an indemnitee
in his or her capacity as a Director or officer (and not in any other capacity
in which service was or is rendered by such indemnitee, including, without
limitation, service to an employee benefit plan) shall be made only upon
delivery to the Company of an undertaking (hereinafter an "undertaking"), by or
on behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal (hereinafter a "final adjudication") that such
indemnitee is not entitled to be indemnified for such expenses under this
Article or otherwise.

      b) If a claim under paragraph (a) of this Article is not paid in full by
the Company within sixty days after a written claim has been received by the
Company, except in the case of a claim for an advancement of expenses, in which
case the applicable period shall be twenty days, the indemnitee may at any time
thereafter bring suit against the Company to recover the unpaid amount of the
claim. If successful in whole or in part in any such suit, or in a suit brought
by the Company to recover an advancement of expenses pursuant to the terms of an
undertaking, the indemnitee shall be entitled to be paid also the expense of
prosecuting or defending such suit. In (i) any suit brought by the indemnitee to
enforce a right to indemnification hereunder (but not in a suit brought by the
indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and (ii) in any suit by the Company to recover an advancement of
expenses pursuant to the terms of an undertaking the Company shall be entitled
to recover such expenses upon a final adjudication that, the indemnitee has not
met the applicable standard of conduct set forth in the Delaware General
Corporation Law. Neither the failure of the Company (including its Board of
Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such suit that indemnification of the
indemnitee is proper in the circumstances because the indemnitee has met the
applicable standard of conduct set forth in the Delaware General Corporation
Law, nor an actual determination by the Company (including its Board of
Directors, independent legal counsel, or its stockholders) that the indemnitee
has not met such applicable standard of conduct, shall create a presumption that
the indemnitee has not met the applicable standard of conduct or, in the case of
such a suit brought by the indemnitee, be a defense to such suit. In any


                                       4


suit brought by the indemnitee to enforce a right to indemnification or to any
advancement of expenses hereunder, or by the Company to recover an advancement
of expenses pursuant to the terms of an undertaking, the burden of proving that
the indemnitee is not entitled to be indemnified, or to such advancement of
expenses, under this Article or otherwise shall be on the Company.

      c) The rights to indemnification and to the advancement of expenses
conferred in this Article shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, this certificate of
incorporation, by-law, agreement, vote of stockholders or disinterested
Directors or otherwise.

      d) The Company may maintain insurance, at its expense, to protect itself
and any Director, officer, employee or agent of the Company or another
corporation, partnership, joint venture, trust or other enterprise against any
expense, liability or loss, whether or not the Company would have the power to
indemnify such person against such person against such expense, liability or
loss under the Delaware General Corporation Law.
