                                  ARTICLE VIII

            A director of the Corporation shall not be personally liable to the
      Corporation of its stockholders for monetary damages for breach of
      fiduciary duty as a director, except 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) under Section 174 of the
      Delaware General Corporation Law, or (iv) for any transaction from which
      the director derived any improper personal benefit. If the Delaware
      General Corporation Law is amended after the filing of this Certificate of
      Incorporation to authorize corporation 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 Delaware General Corporation Law, as so amended.

            Any repeal or modification of the foregoing paragraph by the
      stockholders of 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.

                                   ARTICLE IX

      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, or a person of whom he or she is the legal
representative, is or was a director or officer of the Corporation or is or was
serving at the request of the Corporation as a director or officer 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 or officer or in any other capacity while
serving as a director or officer shall be indemnified and held harmless by the
Corporation 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 Corporation
to provide broader indemnification rights than permitted prior thereto), against
all expense, liability and loss (including, without limitation, attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid or to be 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 or officer and shall inure to the benefit of the
indemnitee's heirs, executors and administrators; provided, however, that,
except for a proceeding brought by an indemnitee to enforce his rights to
indemnification, the Corporation shall indemnify any such indemnitee in
connection with a proceeding (or part thereof) initiated by such indemnitee only
if such proceeding (or part thereof) was



authorized by the board of directors of the Corporation. The right to
indemnification conferred in this Article IX shall be a contract right and shall
include the right to be paid by the Corporation 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 corporation 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 indemnitee led for such expenses under this
Article or otherwise.

      B. If a claim under this Article is not paid in full by the corporation
within a reasonable time after a written claim has been received by the
Corporation, the indemnitee may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim. If successful in whole or
in part in any such suit, or 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) any suit by the corporation to recover an advancement of
expenses pursuant to the terms of an undertaking the Corporation 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 Corporation (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 met
the applicable standard of conduct set forth in the Delaware General Corporation
Law, nor an actual determination by the Corporation (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 in such suit. In any suit
brought by the indemnitee to enforce a right to indemnification or to an
advancement of expenses hereunder or by the Corporation 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
corporation.

      C. The rights to indemnification and to the advancement of expenses
conferred in this Article IX shall not be exclusive of any other right which any
person may have or hereafter acquire under this Certificate of Incorporation or
any bylaw, agreement, vote of stockholders or disinterested directors or
otherwise.



      D. The Corporation may maintain insurance, at its expense, to protect
itself and any director or officer of the Corporation or another corporation,
partnership, joint venture, trust or other enterprise against any such expense,
liability or loss under the Delaware General Corporation Law.

      E. The Corporation may, to the extent authorized from time to time by the
board of directors, grant rights to indemnification and to the advancement of
expenses to any employee or agent of the corporation to the fullest extent of
the provisions of this Article IX with respect to the indemnification and
advancement of expenses of directors and officers of the Corporation.

                                    ARTICLE X

      No stockholder of the Corporation will be entitled to cumulative voting
with respect to the election of directors or, by reason of his holding shares of
any class of capital stock of the Corporation, have any preferential rights to
purchase or subscribe to any shares of any class of capital stock of the
Corporation, or any notes, debentures, bonds, warrants, options or other
securities of the Corporation, now or hereafter authorized.

                                   ARTICLE XI

      Any amendment to this Certificate of Incorporation, any merger or
consolidation of this Corporation with or into another corporation or
joint-stock or other association, any sale, lease or exchange of all or
substantially all of the assets of this corporation, any dissolution of this
Corporation or any alteration of the powers, preference or special rights of the
shares of any class of the capital stock of this corporation shall require the
affirmative vote of the holders of at least two-thirds of the outstanding shares
entitled to vote thereon.

      IN WITNESS WHEREOF, the undersigned incorporator of the Corporation hereby
certifies that the facts herein stated are true, and accordingly has signed this
instrument this 25th day of November, 1987.
