ARTICLE VI

Indemnification

          SECTION 1. Indemnification Respecting Third Party Claims.

          (a) Indemnification of Directors and Officers. To the fullest extent permitted and in the manner required by the laws of the State of Delaware as in effect from time to time, the Corporation shall indemnify in accordance with the following provisions of this Article VI any person who was or is made a party to or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (including any appeal thereof), whether civil, criminal, administrative, regulatory or investigative in nature (other than an action by or in the right of the Corporation), by reason of the fact that such person is or was a director or officer of the Corporation, or, if at a time when he or she was a director or officer of the Corporation, is or was serving at the request of, or to represent the interests of, the Corporation as a director, officer, partner, member, trustee, fiduciary, employee or agent (a “Subsidiary Officer”) of another corporation, partnership, joint venture, limited liability company, trust, employee benefit plan or other enterprise including any charitable or not-for-profit public service organization or trade association (an “Affiliated Entity”), against expenses (including attorneys’ fees and disbursements), costs, judgments, fines, penalties and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such 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 his or her conduct was unlawful; provided, however, that (i) the Corporation shall not be obligated to indemnify a director or officer of the Corporation or a Subsidiary Officer of any Affiliated Entity against expenses incurred in connection with an action, suit, proceeding or investigation to which such person is threatened to be made a party but does not become a party unless such expenses were incurred with the approval of the Board of Directors, a committee thereof or the Chairman or the Chief Executive Officer of the Corporation and (ii) the Corporation shall not be obligated to indemnify against any amount paid in settlement unless the Corporation has consented to such settlement. The termination of any action, suit or proceeding by judgment, order, settlement or 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 such 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, that such person had reasonable cause to believe that his or her conduct was unlawful. Notwithstanding anything to the contrary in the foregoing provisions of this paragraph, a person shall not be entitled, as a matter of right, to indemnification pursuant to this paragraph against costs or expenses incurred in connection with any action, suit or proceeding commenced by such person against the Corporation or any Affiliated Entity or any person who is or was a director, officer, partner, member, fiduciary, employee or agent of the Corporation or a Subsidiary Officer of any Affiliated Entity in their capacity as such, but such indemnification may be provided by the Corporation in a specific case as permitted by Section 6 of this Article.

          (b) Indemnification of Employees and Agents. The Corporation may indemnify any employee or agent of the Corporation in the manner and to the same or a lesser extent that it shall indemnify any director or officer under paragraph (a) above in this Section 1.

          SECTION 2. Indemnification Respecting Derivative Claims.

          (a) Indemnification of Directors and Officers. To the fullest extent permitted and in the manner required by the laws of the State of Delaware as in effect from time to time, the Corporation shall indemnify, in accordance with the following provisions of this Article, any person who was or is made a party to or is threatened to be made a party to any threatened, pending or completed action or suit (including any appeal thereof) brought by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Corporation, or, if at a time when he or she was a director or officer to the Corporation, is or was serving at the request of, or to represent the interests of, the Corporation as a Subsidiary Officer of an Affiliated Entity against expenses (including attorneys’ fees and disbursements) and costs actually and reasonably incurred by such person in connection with such action or suit if such person acted in good faith and in a manner such 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 of Chancery of the State of Delaware or the court in which such judgment was rendered 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 and costs as the Court of Chancery of the State of Delaware or such other court shall deem proper; provided, however, that the Corporation shall not be obligated to indemnify a director or officer of the Corporation or a Subsidiary Officer of any Affiliated Entity against expenses incurred in connection with an action or suit to which such person is threatened to be made a party but does not become a party unless such expenses were incurred with the approval of the Board of Directors, a committee thereof, or the Chairman or the Chief Executive Officer of the Corporation. Notwithstanding anything to the contrary in the foregoing provisions of this paragraph, a person shall not be entitled, as a matter of right, to indemnification pursuant to this paragraph against costs and expenses incurred in connection with any action or suit in the right of the Corporation commenced by such Person, but such indemnification may be provided by the Corporation in any specific case as permitted by Section 6 of this Article VI.

          (b) Indemnification of Employees and Agents. The Corporation may indemnify any employee or agent of the Corporation in the manner and to the same or a lesser extent that it shall indemnify any director or officer under paragraph (a) above in this Section 2.

          SECTION 3. Indemnification in Certain Cases.

          (a) Indemnification Upon Successful Defense. 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 any of paragraphs (a) or (b) in Sections 1 and 2 of this Article VI, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees and disbursements) actually and reasonably incurred by him in connection therewith.

          (b) Indemnification for Service As a Witness. To the extent any person who is or was a director or officer of the Corporation has served or prepared to serve as a witness in any

action, suit or proceeding (whether civil, criminal, administrative, regulatory or investigative in nature), including any investigation by any legislative body or any regulatory or self-regulatory body by which the Corporation’s business is regulated, by reason of his or her services as a director or officer of the Corporation or his or her service as a Subsidiary Officer of an Affiliated Entity at a time when he or she was a director or officer of the Corporation (assuming such person is or was serving at the request of, or to represent the interests of, the Corporation as a Subsidiary Officer of such Affiliated Entity) but excluding service as a witness in an action or suit commenced by such person, the Corporation shall indemnify such person against out-of-pocket costs and expenses (including attorneys’ fees and disbursements) actually and reasonably incurred by such person in connection therewith and shall use its best efforts to provide such indemnity within 45 days after receipt by the Corporation from such person of a statement requesting such indemnification, averring such service and reasonably evidencing such expenses and costs; it being understood, however, that the Corporation shall have no obligation under this Article VI to compensate such person for such person’s time or efforts so expended. The Corporation may indemnify any employee or agent of the Corporation to the same or a lesser extent as it may indemnify any director or officer of the Corporation pursuant to the foregoing sentence of this paragraph.

          SECTION 4. Procedure. Any indemnification under Sections 1 and 2 of this Article VI (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 such person has met the applicable standard of conduct set forth in such Sections 1 and 2. Such determination shall be made (a) 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 in respect of which indemnification is sought or by majority vote of the members of a committee of the Board of Directors composed of at least three members each of whom is not a party to such action, suit or proceeding, or (b) if such a quorum is not obtainable and/or such a committee is not established or obtainable, or, even if obtainable, if a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (c) by the stockholders entitled to vote thereon. In the event a request for indemnification is made by any person referred to in paragraph (a) of Section 1 or 2 of this Article VI, the Corporation shall use its best efforts to cause such determination to be made not later than 90 days after such request is made.

          SECTION 5. Advances for Expenses.

          (a) Advances to Directors and Officers. Expenses and costs, incurred by any person referred to in paragraph (a) of Section 1 or 2 of this Article VI in defending a civil, criminal, administrative, regulatory or investigative action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking in writing by or on behalf of such person to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified in respect of such costs and expenses by the Corporation as authorized by this Article.

          (b) Advances to Employees and Agents. Expenses and costs incurred by any person referred to in paragraph (b) of Section 1 or 2 of this Article VI in defending a civil, criminal, administrative, regulatory or investigative action, suit or proceeding may be paid by the

Corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors, a committee thereof or an officer of the Corporation authorized to so act by the Board of Directors upon receipt of an undertaking in writing by or on behalf of such person to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation in respect of such costs and expenses as authorized by this Article VI.

          SECTION 6. Rights Not Exclusive. The provision of indemnification to or the advancement of expenses and costs to any person under this Article, or the entitlement of any person to indemnification or advancement of expenses and costs under this Article, shall not limit or restrict in any way the power of the Corporation to indemnify or advance expenses and costs to such person in any other way permitted by law or be deemed exclusive of, or invalidate, any right to which any person seeking indemnification or advancement of expenses and costs may be entitled under any law, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s capacity as an officer, director, employee or agent of the Corporation and as to action in any other capacity.

          SECTION 7. Insurance. 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, or to represent the interests of, the Corporation as a Subsidiary Officer of any Affiliated Entity, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Corporation would have the power to indemnify such person against such liability under the provisions of this Article VI or applicable law.

          SECTION 8. Definitions of Certain Terms. For purposes of this Article VI, (i) references to “the Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed into the Corporation in a consolidation or merger if such corporation would have been permitted (if its corporate existence had continued) under applicable law to indemnify its directors, officers, 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, or to represent the interests of, such constituent corporation as a director, officer, employee or agent of any Affiliated Entity shall stand in the same position under the provisions of this Article VI with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued; (ii) references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; (iii) references to “serving at the request of the Corporation” shall include any service as a director, officer, partner, member, trustee, fiduciary, employee or agent of the Corporation or any Affiliated Entity which service imposes duties on, or involves services by, such director, officer, partner, member, trustee, fiduciary, employee or agent with respect to an employee benefit plan, its participants, or beneficiaries and (iv) a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interest of the Corporation” as referred to in this Article VI.

          SECTION 9. Accrual of Claims; Survival of Rights. The indemnification provided or permitted under the foregoing provisions of this Article VI shall or may, as the case may be, apply in respect of any expense, cost, judgment, fine, penalty or amount paid in settlement, whether or not the claim or cause of action in respect thereof accrued or arose before or after the effective date of such provisions of this Article VI. The indemnification and advancement of expenses provided by, or granted pursuant to this Article VI 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.

          SECTION 10. Corporate Obligations; Reliance. The provisions of this Article VI shall be deemed to create a binding obligation on the part of the Corporation to the persons who from time to time are elected officers or directors of the Corporation, and such persons in acting in their capacities as officers or directors of the Corporation or Subsidiary Officers of any Affiliated Entity shall be entitled to rely on such provisions of this Article, without giving notice thereof to the Corporation.
