INDEMNIFICATION AND ADVANCEMENT OF EXPENSES

(a) Each person who was or is a party or is threatened to be made a party to, or was or is otherwise involved in, any action, suit, arbitration, alternative dispute mechanism, inquiry, judicial, administrative or legislative hearing, investigation or any other threatened, pending or completed proceeding, whether brought by or in the right of the Corporation or otherwise, including any and all appeals, whether of a civil, criminal, administrative, legislative, investigative or other nature (hereinafter a “ proceeding ”), by reason of the fact that he or she is or was a director, or an officer designated or appointed pursuant to Section 5.1, of the Corporation or while a director or officer of the Corporation

17

is or was serving at the request of the Corporation as a director, officer, employee, agent or trustee of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (hereinafter an “ indemnitee ”), or by reason of anything done or not done by him or her in any such capacity, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended, against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement by or on behalf of the indemnitee) actually and reasonably incurred by such indemnitee in connection therewith; provided , however , that, except as otherwise required by law or provided in Section 6.3 with respect to proceedings to enforce rights under this Article VI, the Corporation shall indemnify any such indemnitee in connection with a proceeding, or part thereof, initiated by such indemnitee (including claims and counterclaims, whether such counterclaims are asserted by (i) such indemnitee, or (ii) the Corporation in a proceeding initiated by such indemnitee) only if such proceeding, or part thereof, was authorized or ratified by the Board of Directors.

(b) To receive indemnification under this Section 6.1, an indemnitee shall submit a written request to the Secretary of the Corporation. Such request shall include documentation or information that is necessary to determine the entitlement of the indemnitee to indemnification and that is reasonably available to the indemnitee. Upon receipt by the Secretary of the Corporation of such a written request, the entitlement of the indemnitee to indemnification shall be determined by the following person or persons who shall be empowered to make such determination: (i) the Board of Directors by a majority vote of the directors who are not parties to such proceeding, whether or not such majority constitutes a quorum, (ii) a committee of such directors designated by a majority vote of such directors, whether or not such majority constitutes a quorum, (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to the indemnitee, (iv) the stockholders of the Corporation or (v) in the event that a change of control (as defined below) has occurred, by independent legal counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to the indemnitee. The determination of entitlement to indemnification shall be made and, unless a contrary determination is made, such indemnification shall be paid in full by the Corporation not later than 60 days after receipt by the Secretary of the Corporation of a written request for indemnification. For purposes of this Section 6.1(b), a “ change of control ” will be deemed to have occurred if the individuals who, as of the effective date of these Bylaws, constitute the Board of Directors (the “ incumbent board ”) cease for any reason to constitute at least a majority of the Board of Directors; provided , however , that any individual becoming a director subsequent to such effective date whose election, or nomination for election by the stockholders of the Corporation, was approved by a vote of at least a majority of the directors then comprising the incumbent board shall be considered as though such individual were a member of the incumbent board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board of Directors.

18

Section 6.2 Right to Advancement of Expenses .

(a) In addition to the right to indemnification conferred in Section 6.1, an indemnitee shall, to the fullest extent not prohibited by law, also have the right to be paid by the Corporation the expenses (including attorneys’ fees) incurred in defending any proceeding with respect to which indemnification is required under Section 6.1 in advance of its final disposition (hereinafter an “ advancement of expenses ”); provided , however , that an advancement of expenses 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 of a court of competent jurisdiction 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 Article VI or otherwise.

(b) To receive an advancement of expenses under this Section 6.2, an indemnitee shall submit a written request to the Secretary of the Corporation. Such request shall reasonably evidence the expenses incurred by the indemnitee and shall include or be accompanied by the undertaking required by Section 6.2(a). Each such advancement of expenses shall be made within 20 days after the receipt by the Secretary of the Corporation of a written request for advancement of expenses.

Section 6.3 Right of Indemnitee to Bring Suit . In the event that a determination is made that the indemnitee is not entitled to indemnification or if payment is not timely made following a determination of entitlement to indemnification pursuant to Section 6.1(b) or if an advancement of expenses is not timely made under Section 6.2(b), the indemnitee may at any time thereafter bring suit against the Corporation in a court of competent jurisdiction in the State of Delaware seeking an adjudication of entitlement to such indemnification or advancement of expenses. 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 to the fullest extent permitted by law. In 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 the indemnitee has not met any applicable standard of conduct for indemnification set forth in the DGCL. Further, 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 of conduct for indemnification set forth in the DGCL. 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 DGCL, 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

19

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 applicable law, this Article VI or otherwise shall be on the Corporation.

Section 6.4 Non-Exclusivity of Rights . The rights to indemnification and to the advancement of expenses conferred in this Article VI shall not be exclusive of any other right which any person may have or hereafter acquire under any law, agreement, vote of stockholders or disinterested directors, provisions of a certificate of incorporation or bylaws, or otherwise.

Section 6.5 Insurance . The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Section 6.6 Indemnification of Employees and Agents of the Corporation . The Corporation may, to the extent and in the manner permitted by applicable law, and to the extent authorized from time to time, grant rights to indemnification and to the advancement of expenses to any employee or agent of the Corporation.

Section 6.7 Nature of Rights . The rights conferred upon indemnitees in this Article VI shall be contract rights and such rights shall continue as to an indemnitee who has ceased to be a director, officer or trustee and shall inure to the benefit of the indemnitee’s heirs, executors and administrators. Any amendment, alteration or repeal of this Article VI that adversely affects any right of an indemnitee or its successors shall be prospective only and shall not limit or eliminate any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment, alteration or repeal.

Section 6.8 Settlement of Claims . Notwithstanding anything in this Article VI to the contrary, the Corporation shall not be liable to indemnify any indemnitee under this Article VI for any amounts paid in settlement of any proceeding effected without the Corporation’s written consent, which consent shall not be unreasonably withheld, or for any judicial award if the Corporation was not given a reasonable and timely opportunity, at its expense, to participate in the defense of such proceeding.

Section 6.9 Subrogation . In the event of payment under this Article VI, the Corporation shall be subrogated to the extent of such payment to all of the rights of recovery of the indemnitee, who shall execute all papers required and shall do everything that may be necessary to secure such rights, including the execution of such documents necessary to enable the Corporation effectively to bring suit to enforce such rights.

20

Section 6.10 Severability . If any provision or provisions of this Article VI shall be held to be invalid, illegal or unenforceable for any reason whatsoever, (a) the validity, legality and enforceability of the remaining provisions of this Article VI (including, without limitation, all portions of any paragraph of this Article VI containing any such provision held to be invalid, illegal or unenforceable, that are not by themselves invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby, and (b) to the fullest extent possible, the provisions of this Article VI (including, without limitation, all portions of any paragraph of this Article VI containing any such provision held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable) shall be construed so as to give effect to the intent of the parties that the Corporation provide protection to the indemnitee to the fullest enforceable extent.
