INDEMNIFICATION

SECTION 1. SUITS BY THIRD PARTIES. The Corporation shall indemnify any person who was or is made 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 (other than an action by or in the right of the Corporation) by reason of the fact that the person 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 corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, will not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the Corporation, or, with respect to any criminal action or proceeding, had reasonable cause to believe that the conduct was unlawful.

SECTION 2. DERIVATIVE SUITS. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that the person 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 corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person 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 action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

SECTION 3. INDEMNIFICATION AS OF RIGHT. To the extent that a director, officer, employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Sections 1 and 2 of this Article, or in defense of any claim, issue or matter therein, the person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection therewith.

SECTION 4. DETERMINATION THAT INDEMNIFICATION IS PROPER. Any indemnification under Sections 1 and 2 of this Article (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Sections 1 and 2. Such determination will be made (1) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable and a quorum of disinterested directors so directs, by independent legal counsel (compensated by the Corporation) in a written opinion, or (3) by the

stockholders.

SECTION 5. ADVANCE OF FUNDS. Expenses (including attorneys’ fees) incurred by an officer, director, employee or agent in defending a civil, criminal, administrative or investigative action, suit or proceeding, or threat thereof, shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors in the specific case upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount if it shall ultimately be determined that the person is not entitled to be indemnified by the Corporation as authorized in this Article.

SECTION 6. NON-EXCLUSIVITY. The indemnification and advancement of expenses provided by, or granted pursuant to, the other Sections of this Article shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any 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.

SECTION 7. SUCCESSORS AND ASSIGNS. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article shall, unless otherwise provided, when authorized or ratified continue as to a person who has ceased to be a director, officer or agent and shall inure to the benefit of the heirs, executors and administrators of such person.

SECTION 8. INSURANCE PREMIUMS. The Corporation may purchase and maintain insurance on behalf of any person who 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 corporation, partnership, joint venture, trust or other enterprise against any liability asserted against the person and incurred by him in any such capacity, or arising out of the person's status as such, whether or not the Corporation would have the power to indemnify him against such liability under the provisions of this Article.

SECTION 9. REFERENCES TO "CORPORATION". References in this Article to "the Corporation" will 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, will 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.

SECTION 10. REFERENCES TO CERTAIN TERMS. For purposes of this Article, references to "other enterprises" will include employee benefit plans; references to "fines" will include any excise taxes assessed on a person with respect to an employee benefit plan; and references to "serving at the request of the Corporation" will include any service as a director, officer, employee or agent of a subsidiary of the Corporation and any 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 interest of the participants and beneficiaries of an employee benefit plan will be deemed to have acted in a manner "not opposed to the best interests of the Corporation" as referred to in this Article.

SECTION 11. APPLICATION OF ARTICLE. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article shall, unless otherwise provided, when authorized or ratified continue as to a person who has ceased to be a director, officer or agent and shall inure to the benefit of the heirs, executors and administrators of such person.

SECTION 12. RETROACTIVE EFFECT. The provisions of this Article will be deemed retroactive and will include all acts of the officers and directors of the Corporation since the date of incorporation.
