The Corporation may, and to the extent required by law, shall, in advance of any meeting of stockholders, appoint one or more inspectors to act at the meeting and make a written report thereof. The Corporation may designate one or more alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the person presiding at the meeting may, and to the extent required by law, shall, appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability.

ARTICLE VIII

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 8.1 Mandatory Indemnification of Directors and Officers. The Corporation shall indemnify and hold harmless to the full extent permitted by the laws of the State of Delaware as from time to time in effect any person who was or is a party or is threatened to be made a party to, or is otherwise involved in, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not an action by or in the right of the Corporation) (hereinafter a “proceeding”), by reason of the fact that he or she is or was a director or officer of the Corporation, or, while serving as a director or officer of the Corporation, 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 (hereinafter an “indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith; provided, however, that, except as provided in Section 8.2 with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation. The right to indemnification conferred by this Section 8.1 also shall include the right of such persons described in this Section 8.1 to be paid in advance by the Corporation for their expenses (including attorneys’ fees) incurred in defending any such proceeding in advance of its final disposition (hereinafter an “advancement of expenses”) to the full extent permitted by the laws of the State of Delaware, as from time to time in effect; provided, however, that, if the GCL requires, an advancement of expenses incurred by an indemnitee in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such indemnitee) shall be made only upon delivery to the Corporation of an undertaking (hereinafter an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (hereinafter a “final adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under this Section 8.1 or otherwise. The right to indemnification conferred on such persons by this Section 8.1 shall be a contract right.

Section 8.2 Right of Indemnitee to Bring Suit. If a claim under Section 8.1 of these Bylaws is not paid in full by the Corporation within sixty (60) days after a written claim has been received by the Corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty (20) days, the indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit. In (i) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) in any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that, the indemnitee has not met any applicable standard for indemnification set forth in the GCL. Neither the failure of the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances because the indemnitee has met the applicable standard of conduct set forth in the GCL, nor an actual determination by the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) that the indemnitee has not met such applicable standard of conduct, shall create a presumption that the indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the indemnitee, be a defense to such suit. In any suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article VIII or otherwise shall be on the Corporation.

Section 8.3 Permissive Indemnification of Non-Officer Employees and Agents. The Corporation may 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 (whether or not an action by or in the right of the Corporation) by reason of the fact that the person is or was an employee (other than an officer) or agent of the Corporation, or, while serving as an employee (other than an officer) or agent of the Corporation, 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, to the extent (i) permitted by the laws of the State of Delaware as from time to time in effect, and (ii) authorized in the sole discretion of the Chief Executive Officer and at least one other of the following officers: the President, the Chief Financial Officer, or the General Counsel of the Corporation (the Chief Executive Officer and any of such other officers so authorizing such indemnification, the “Authorizing Officers”). The Corporation may, to the extent permitted by Delaware law and authorized in the sole discretion of the Authorizing Officers, pay expenses (including attorneys’ fees) reasonably incurred by any such employee or agent in defending any civil, criminal, administrative or investigative action, suit or proceeding in advance of the final disposition of

-13-

such action, suit or proceeding, upon such terms and conditions as the Authorizing Officers authorizing such expense advancement determine in their sole discretion. The provisions of this Section 8.3 shall not constitute a contract right for any such employee or agent.

Section 8.4 General Provisions. The rights and authority conferred in any of the Sections of this Article VIII shall not be exclusive of any other right which any person seeking indemnification or advancement of expenses may have or hereafter acquire under any statute, provision of the Restated Certificate of Incorporation or these Bylaws, agreement, vote of stockholders or disinterested Directors or otherwise, both as to action in his or her 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, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. Neither the amendment or repeal of this Article VIII or any of the Sections thereof nor the adoption of any provision of the Restated Certificate of Incorporation or these Bylaws or of any statute inconsistent with this Article VIII or any of the Sections thereof shall eliminate or reduce the effect of this Article VIII or any of the Sections thereof in respect of any acts or omissions occurring prior to such amendment, repeal or adoption or an inconsistent provision.
