Section 1. Nature of Indemnity. Each person who was 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, fiduciary, 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, fiduciary or agent or in any other capacity while serving as a director, officer, employee, fiduciary or agent, shall be indemnified and held harmless by the Corporation to the fullest extent which it is empowered to do so by the DGCL, 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 actually and reasonably incurred by such person in connection with such proceeding and such indemnification shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that, except as provided in Section 2 of this Article Eight, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding initiated by such person only if such proceeding was authorized by the Board of Directors of the Corporation.

Section 2. Procedure for Indemnification of Directors and Officers. Any indemnification of a director or officer of the Corporation under Section 1 of this Article Eight or advance of expenses under Section 5 of this Article Eight shall be made promptly, and in any event within 30 days, upon the written request of the director or officer. If a determination by the Corporation that the director or officer is entitled to indemnification pursuant to this Article Eight is required, and the Corporation fails to respond within 60 days to a written request for indemnity, the Corporation shall be deemed to have approved the request. If the Corporation denies a written request for indemnification or advancing of expenses, in whole or in part, or if payment in full pursuant to such request is not made within 30 days, the right to indemnification or advances as granted by this Article Eight shall be enforceable by the director or officer in any court of competent jurisdiction. Such person’s costs and expenses incurred in connection with

successfully establishing his right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation. 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, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of such defense shall be on the Corporation. Neither the failure of the Corporation (including the 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 DGCL, 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.

Section 3. Nonexclusivity of Article Eight. The rights to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Article Eight shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the certificate of incorporation, bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

Section 4. Insurance. The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was a director, officer, employee, fiduciary, or agent of the Corporation 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 him or her and incurred by him or her in any such capacity, whether or not the Corporation would have the power to indemnify such person against such liability under this Article Eight.

Section 5. Expenses. Expenses incurred by any person described in Section 1 of this Article Eight in defending a proceeding shall be paid by the Corporation in advance of such proceeding’s final disposition unless otherwise determined by the Board of Directors in the specific case upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the Corporation. Such expenses incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Board of Directors deems appropriate.

Section 6. Employees and Agents. Persons who are not covered by the foregoing provisions of this Article Eight and who are or were employees or agents of the Corporation, or who are or were serving at the request of the Corporation as employees or agents of another corporation, partnership, joint venture, trust or other enterprise, may be indemnified to the extent authorized at any time or from time to time by the Board of Directors.

Section 7. Contract Rights. The provisions of this Article Eight shall be deemed to be a contract right between the Corporation and each director or officer who serves in any such capacity at any time while this Article Eight and the relevant provisions of the DGCL or other applicable law are in effect, and any repeal or modification of this Article Eight or any such

law shall not affect any rights or obligations then existing with respect to any state of facts or proceeding then existing.

Section 8. Merger or Consolidation. For purposes of this Article Eight, 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 this Article Eight with respect to the resulting or surviving corporation as he or she would have with respect to such constituent corporation if its separate existence had continued.
