To the maximum extent permitted from time to time under the law of the State of Delaware, the Corporation renounces any interest or expectancy of the Corporation in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to its officers, directors or stockholders, other than those officers, directors or stockholders who are employees of the Corporation. No amendment or repeal of this ARTICLE ELEVEN shall apply to or have any effect on the liability or alleged liability of any officer, director or stockholder of the Corporation for or with respect to any opportunities of which such officer, director, or stockholder becomes aware prior to such amendment or repeal.

ARTICLE TWELVE

The Corporation will indemnify, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”) by reason of the fact that he, or a person for whom he 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, enterprise or nonprofit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys’ fees) incurred by such person. Such right of indemnification will inure whether or not the claim asserted is based on matters which antedate the adoption of this Article Twelve. The Corporation will be required to indemnify or make advances to a person

in connection with a proceeding (or part thereof) initiated by such person only if the proceeding (or part thereof) was authorized by the board of directors.

The Corporation will pay the expenses (including attorneys’ fees) incurred by a director or officer in defending any proceeding in advance of its final disposition; provided, however, that the payment of expenses incurred by a director or officer in advance of the final disposition of the proceeding will be made only upon receipt of an undertaking by the director or officer to repay all amounts advanced if it should be ultimately determined that the director or officer is not entitled to be indemnified under this Article Twelve or otherwise.

If a claim for indemnification or payment of expenses under this Article Twelve is not paid in full within 60 days after a written claim therefor has been received by the Corporation, the claimant may file suit to recover the unpaid amount of such claim and, if successful, will be entitled to be paid the expense (including attorney’s fees) of prosecuting such claim to the fullest extent permitted by Delaware law. In any such action the Corporation will have the burden of proving that the claimant was not entitled to the requested indemnification or payment of expenses under applicable law.

The rights conferred on any person by this Article Twelve will not be exclusive of any other rights which such person may have or hereafter acquire under any statute, provision of this Certificate, the bylaws, agreement, vote of stockholders or resolution of disinterested directors or otherwise.

The Corporation’s obligation, if any, to indemnify any person who was or is serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or nonprofit entity will be reduced by any amount such person may collect as indemnification from such other corporation, partnership, joint venture, trust, enterprise or nonprofit entity.

Any amendment, modification or repeal of the foregoing provisions of this Article Twelve will not adversely affect any right or protection hereunder of any person in respect of any act or omission occurring prior to the time of such amendment, modification or repeal.
