shall have power under applicable law to do so and in a manner permitted by such

applicable law to do so and in a manner permitted by such law, any person made
or threatened to be made a party to any threatened, pending or completed action,

indemnification and advancement of expenses provided by or granted pursuant to
this Article EIGHTH shall not be deemed exclusive of any other rights to which
any person indemnified or being advanced expenses may be entitled under any
statute, By-Law, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person

to the benefits of the heirs, executors and administrators of such person.

         The corporation may purchase and maintain insurance on behalf of any
person referred to in the preceding paragraph against any liability asserted
against him and incurred by him in any such capacity, or arising out of his
status as such, whether or not the corporation would have the power to indemnify
him against such liability under the provisions of this Article EIGHTH or
otherwise.

         For purposes of this Article EIGHTH, references to "the Corporation"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Article with
respect to the resulting or surviving corporation as he would have with respect
to such constituent corporation if its separate existence had continued.

         The provisions of this Article EIGHTH shall be deemed to be a contract
between the Corporation and each director or officer who serves in any such
capacity at any time while this Article and the relevant provisions of the
General Corporation Law of the State of Delaware or other applicable law, if
any, are in effect, and any repeal or modification of any such law or of this
Article shall not affect any rights or obligations then existing with respect to
any state of facts then or theretofore existing or any action, suit or
proceeding theretofore or thereafter brought or threatened based in whole or in
part upon any such state of facts.

taxes assessed on a person with respect to an employee benefit plan; and

service as a director, officer, employee or agent of the Corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the best interest of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner not opposed to the best interests of the Corporation.

         NINTH. The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the

prescribed by statute, and all rights conferred upon stockholders herein are
granted subject to this reservation.

         TENTH. Whenever a compromise or arrangement is proposed between the
Corporation and its creditors or any class of them and/or between the
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the Corporation under the
provisions of Section 291 of Title 8 of the Delaware Code or on the application
of trustees in dissolution or of any receiver or receivers appointed for the
Corporation under the provisions of Section 279 of Title 8 of the Delaware Code
order a meeting of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of the Corporation, as the case may be, to
be summoned in such manner as the said court directs. If a majority in number
representing three-fourths in value of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of the Corporation, as the
case may be, agree to any compromise or arrangement and to any reorganization of
the Corporation as consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders or class of
stockholders, of the Corporation, as the case may be, and also on the
Corporation.

         ELEVENTH. No director of the Corporation shall be 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 General Corporation Law of the
State of Delaware, or (iv) for any transaction from which the director derived
an improper personal benefit.

         The undersigned incorporator, for the purpose of forming a corporation
pursuant to the General Corporation Law of the State of Delaware, has signed
this Certificate this 28th day of October, 2003.
