Section 11. Indemnity.

(a) Right to Indemnification. The Corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”) (other than an action by or in the right of the Corporation) by reason of the fact that he is or was a Director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a Director, officer, employee or agent of another entity, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best

- 4 -

interests of the Corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not of itself create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interest of the Corporation and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

The Corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed proceeding by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he is or was a Director, officer, employee or agent of the Corporation, or is or was serving at the request of the corporation as a Director, officer, employee or agent of another entity, against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation, unless and only to the extent that the court in which such proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

To the extent that a Director or officer of the Corporation has been successful on the merits or otherwise in defense of any proceeding, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith.

(b) Determination that Indemnification is Proper. Any indemnification under this Section (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification is proper in the circumstances because the individual has met the applicable standard of conduct set forth in subsection (a). Such determination shall be made (1) by the members of the Board of Directors who were not parties to such proceeding, or (2) if such a quorum is not obtainable or, even if obtainable, a quorum of disinterested Directors so directs, by independent legal counsel in a written opinion, or (3) by the shareholders.

(c) Advances. Expenses incurred in defending a proceeding shall be paid by the Corporation in advance of the final disposition of such proceeding upon receipt of an undertaking by or on behalf of the Director or officer of the Corporation to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation as authorized in this Section. Such undertaking shall be an unlimited, unsecured general obligation of the Director or officer and shall be accepted without reference to his ability to make repayment.

(d) Insurance. The Corporation shall have the power to purchase and maintain insurance on behalf of any person who is or was a Director or officer of the Corporation, or is or was serving at the request of the Corporation as Director, officer, employee or agent of another

- 5 -

entity, 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 Section.

(e) Non-Exclusivity of Rights. The indemnification provided by this Section shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any by-law, agreement, vote of shareholders 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 who has ceased to be a Director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

(f) Severability. If any provision of this Section or its application to any person or circumstance is held invalid by a court of competent jurisdiction, the invalidity shall not affect other provisions or applications of this Section, and to this end the provisions of this Section are severable.

Section 12. Chairman of the Board. There shall be a Chairman of the Board of Directors, who shall be chosen by, and serve at the pleasure of, the Board of Directors.
