                                   ARTICLE VII

                  In furtherance and not in limitation of the powers conferred
by the laws of the State of Delaware:

                                       -1-



                  (A)  The board of directors of the corporation is expressly
authorized to adopt, amend or repeal the By-Laws of the corporation.

                  (B)  Elections of directors need not be by written ballot
unless the By-Laws of the corporation shall so provide.

                  (C)  The books of the corporation may be kept at such place
within or without the State of Delaware as the By-Laws of the corporation may
provide or as may be designated from time to time by the board of directors of
the corporation.

                                  ARTICLE VIII

                  (A)  No Personal Liability. A director of the corporation
shall not be personally liable to the corporation or its stockholders for
monetary damages for 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 the director derived an improper personal benefit.

                  (B)  Indemnification. Each person who is or is made a party or
is threatened to be made a party to or is 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, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to
employee benefit plans, 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 said 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 or to be paid
in settlement) reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has ceased
to be a director, officer, employee or agent and shall inure to the benefit of
his or her heirs, executors and administrators; provided, however, that, except
as provided in the second paragraph hereof, the corporation shall indemnify any
such person seeking indemnification in connection with a proceeding (or part
thereof) initiated by such person only if such proceeding (or part thereof) was
authorized by the Board of Directors of the corporation. The right to
indemnification conferred in this section shall be a contract right and shall
include the right to be paid by the corporation any expenses incurred in
defending any such proceeding in advance of its final disposition; provided,
however, that, if the Delaware General Corporation Law requires, the payment of
such expenses incurred by a director or officer in his or her capacity as a
director or officer (and not in any other capacity in which

                                       -2-



service was or is rendered by such person while a director or officer,
including, without limitation, service to an employee benefit plan) in advance
of the final disposition of a 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 shall ultimately be determined that such
director or officer is not entitled to be indemnified under this section or
otherwise. The corporation may, by action of its Board of Directors, provide
indemnification to employees and agents of the corporation with the same scope
and effect as the foregoing indemnification of directors and officers.

                  If a claim under the first paragraph of this section is not
paid in full by the corporation within thirty (30) days after a written claim
has been received by the corporation, the claimant may at any time thereafter
bring suit against the corporation to recover the unpaid amount of the claim
and, if successful in whole or in part, the claimant shall be entitled to be
paid also the expense of prosecuting such claim. It shall be a defense to any
such action (other than an action brought to enforce a claim for expenses
incurred in defending any proceeding in advance of its final disposition where
the required undertaking, if any is required, has been tendered to the
corporation) that the claimant has not met the standards of conduct which make
it permissible under the Delaware General Corporation Law for the corporation to
indemnify the claimant for the amount claimed, but the burden of proving such
defense shall be on the corporation. 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
action that indemnification of the claimant is proper in the circumstances
because he or she 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 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.

                  The right to indemnification and the payment of expenses
incurred in defending a proceeding in advance of its final disposition conferred
in this section shall not be exclusive of any other right which any person may
have or hereafter acquire under any statute, provision of the Restated
Certificate of Incorporation, Bylaw, agreement, vote of stockholders or
disinterested directors or otherwise.

                  (C) 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 such 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.

                  (D) If the Delaware General Corporation Law is hereafter
amended to authorize the further elimination or limitation of the liability of a
director, 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.

                                       -3-



                  (E) Any repeal or modification of the foregoing provisions of
this Article VIII shall not adversely affect any right or protection of any
director, officer, employee or agent of the corporation existing at the time of
such repeal or modification.

                                   ARTICLE IX

                  The corporation reserves the right to amend or repeal any
provision contained in this Certificate of Incorporation, in the manner now or
hereafter prescribed by statute, and all rights conferred upon a stockholder
herein are granted subject to this reservation.

                  I, THE UNDERSIGNED, being the sole incorporator hereinabove
named, for the purpose of forming a corporation pursuant to Delaware General
Corporation Law of the State of Delaware, do make this certificate, hereby
declaring and certifying that said instrument is my act and deed and that the
facts stated herein are true, and accordingly executed this Certificate of
Incorporation as of April 16, 2002.

                                                  ------------------------------
