         THREE:   The purpose of the Corporation is to engage in any lawful act
or activity for which a corporation may be organized under the Delaware General

         FOUR:    The Corporation is authorized to issue one class of stock
which will be designated "Common Stock." The total number of shares of Common

         FIVE:    The following provisions are inserted for the management of
the business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

                  A.       The business and affairs of the Corporation shall be
         managed by or under the direction of the Board of Directors. In
         addition to the powers and authority expressly conferred upon them by
         statute or by this Certificate of Incorporation or the Bylaws of the
         Corporation, the directors are hereby empowered to exercise all such
         powers and do all such acts and things as may be exercised or done by
         the Corporation.

                  B.       The Board of Directors may adopt, amend or repeal the
         Bylaws of the Corporation.

                  C.       The directors of the Corporation need not be elected
         by written ballot unless the Bylaws so provide.

         SIX:     The Corporation reserves the right to amend and repeal any
         provision contained in this Certificate of Incorporation in the manner
         from time to time prescribed by the laws of the State of Delaware. All
         rights herein conferred are granted subject to this reservation.



         SEVEN:   A director of the Corporation shall not be personally liable
to the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, except for 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 such director derived any
improper personal benefit. This Article SEVEN is also contained in Article VIII,
Section 1, of the Corporation's Bylaws. No amendment to or repeal of this
Article SEVEN 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. If the
Delaware General Corporation Law is amended to authorize corporate action
further eliminating 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 amended. Any repeal or
modification of this provision shall not adversely affect any right or
protection of a director of the Corporation existing at the time of such repeal
or modification.

         EIGHT:   A. Right to Indemnification. 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 or as officer of the Corporation or is or was serving at
the request of the Corporation 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 while serving as a director, officer, employee or agent,
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 such law permitted the Corporation to provide prior to such
amendment), 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; provided, however, that, except as provided in Section C of this
Article EIGHT with respect to proceedings to enforce 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.

                  B. Right to Advancement of Expenses. The right to
indemnification conferred in Section A of this Article EIGHT shall include
the right to be paid by the Corporation the expenses (including attorneys' fees)
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

                                      -2-


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 indemnified for
such expenses under this Section B or otherwise. The rights to indemnification
and to the advancement of expenses conferred in Sections A and B of this Article
EIGHT shall be contract rights and such rights shall continue as to an
indemnitee who has ceased to be a director, officer, employee or agent and shall
to the benefit of the indemnitee's heirs, executors and administrators.

                  C.       Right of Indemnitee to Bring Suit. If a claim under
Section A or B of this Article EIGHT is not paid in full by the Corporation
within sixty (60) days after a written claim has been received by the
Corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty (20) days, 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 in a
suit brought by the Corporation 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 brought 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 any applicable standard for indemnification 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 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
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 to such suit. In any suit brought by the indemnitee to
enforce a right to indemnification or to an advancement of expenses hereunder,
or brought by the Corporation to recover an advancement or 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 EIGHT or otherwise shall be on the Corporation.

                  D.       Non-Exclusivity of Rights. The rights to
indemnification and to the advancement of expenses conferred in this Article
EIGHT shall not be exclusive of any other right which any person may have or
hereafter acquire under any statute, the Corporation's Certificate of
Incorporation, Bylaws, agreement, vote of stockholders or disinterested
directors or otherwise.

                                      -3-


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

                  F.       Indemnification of Employees and Agents of the
Corporation. 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 with respect to the indemnification and
advancement of expenses of directors and officers of the Corporation.

                  G.       Amendment. This Article EIGHT is also contained in
Article VIII, Sections 2 through 7, of the Corporation's Bylaws. Any repeal or
modification of this Article EIGHT shall not change the rights of any officer or
director to indemnification with respect to any action or omission occurring
prior to such repeal or modification.

                  follows:
