Section 1. Discretionary Indemnification. Every person who was or is an officer, employee or agent of the Corporation or was or is serving at the request of the Corporation as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust or other enterprise, or any other person connected with the business of the Corporation who the board of directors may designate, may, in the discretion of the board of directors, be indemnified by the Corporation against all liability and expenses actually and reasonably incurred by such person in connection with or resulting from any action, suit or proceeding in which such person may become involved, as a party or otherwise, by reason of such person’s having been or being an officer, employee or agent of the Corporation or a director, officer, employee or agent of such other corporation, partnership, joint venture, trust or other enterprise, or by reason of such person’s connection with the business of the Corporation (including, without limitation, any suit brought by or in the name of the Corporation to recover an advancement of expenses made by the Corporation pursuant to an undertaking or otherwise), provided (a) that such action, suit or proceeding is prosecuted to a final determination and such person defends successfully on the merits or otherwise or, (b) in the absence of such a final determination in such person’s favor, that the Corporation determines that such person acted in good faith and in a manner he 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 no reasonable cause to believe his conduct was unlawful. The determinations contemplated by subclause (b) of the proviso clause of the preceding sentence shall be made, with respect to a person who is a director or officer at the time of such determination, (i) by the board of directors by a majority vote of the directors not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by a majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the stockholders. If a person meets the requirements set forth in the proviso clause of the first sentence of this Section 1 with respect to some matters in an action, suit or proceeding, but not with respect to others, he may be entitled to indemnification as to the former. The provisions of this Section 1 are in addition to, and not by way of limitation of, the provisions of Sections 2 and 3 of this Article IX.

Section 2. Mandatory Indemnification in General. To the extent that a former or present Qualifying Person or officer of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 1 of this Article IX, or in defense of any claim, issue or matter therein, or in any action, suit or proceeding brought by such person to enforce a right to indemnification or to advancement of expenses hereunder, such person shall be indemnified against expenses actually and reasonably incurred by such person in connection therewith. The provisions of this Section 2 are in addition to, and not by way of limitation of, the provisions of Sections 1 and 3 of this Article IX.

Section 3. Mandatory Indemnification of Qualifying Persons. Every person who was or is a Qualifying Person of the Corporation shall be indemnified by the Corporation against all liability and expenses actually and reasonably incurred by such person in connection with or resulting from any action, suit or proceeding in which such person may become involved, as a party or otherwise, by reason of such person’s having been or being a Qualifying Person, or by reason of such person’s connection with the business of the Corporation, provided that the Corporation determines that such person acted in good faith and in a manner he 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 no reasonable cause to believe his conduct was unlawful. Notwithstanding the provisions of the foregoing sentence, except as provided in Section 2 of this Article IX with respect to actions, suits and proceedings to enforce rights to indemnification or advancement of expenses, the Corporation shall be required to indemnify a Qualifying Person in connection with an action, suit or proceeding (or part thereof) initiated by such Qualifying Person only if such action, suit or proceeding (or part thereof) was authorized by the board of directors. The determinations contemplated by the proviso clause of the first sentence of this Section 3 shall be made, with respect to a person who is a director or officer at the time of such determination, (a) by the board of directors by a majority vote of the directors who are not parties to such action, suit or proceedings, even though less than a quorum, or (b) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (c) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (d) by the stockholders. If a Qualifying Person meets the requirements as set forth in the proviso clause of the first sentence of this Section 3 with respect to some matters in an action, suit or proceeding, but not with respect to others, he shall be entitled to indemnification as to the former. The provisions of this Section 3 are in addition to, and not by way of limitation of, the provisions of Sections 1 and 2 of this Article IX.

Section 4. Actions by or in the Right of the Corporation. In the case of any action, suit or proceeding by or in the right of the Corporation: (a) no indemnification shall be made with respect to any claim, issue or matter as to which the person seeking indemnification shall have been adjudged to be liable to the Corporation unless, and only to the extent that, the Delaware Court of Chancery or 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 reasonable expenses as the Court of Chancery or such other court shall deem proper; and (b) indemnification shall extend only to expenses and specifically shall not extend to any liability.

Section 5. Advances of Expenses. Advances against expenses may be made by the Corporation on terms fixed by the board of directors subject to an obligation to repay if indemnification proves unwarranted. Expenses actually and reasonably incurred by a person in defending any action, suit or proceeding in which such person is involved as a party or otherwise by reason of such person’s having been or being a Qualifying Person or in any action, suit or proceeding brought by such person to enforce a right to indemnification or to advancement of expenses hereunder shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such person to repay such amounts if it is ultimately determined that such person is not entitled to be indemnified by the Corporation.

Section 6. Applicability. The indemnification provided by this Article IX shall not be deemed exclusive of any other rights to which any person seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in an official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to hold the office entitling him to indemnification hereunder and shall inure to the benefit of the heirs, executors and administrators of such a person. This Article IX shall not be construed to authorize indemnification in any case or for any liability or expense where such indemnification would not be lawful. This Article IX shall be applicable to actions, suits or proceedings made or commenced after the adoption hereof, whether arising from acts or omissions to act occurring before or after the adoption hereof.

Section 7. Insurance. The Corporation may purchase and maintain insurance on behalf of any person who was or is a Qualifying Person, or on behalf of any person connected with the business of the Corporation, against all liability and expenses incurred by him in any such capacity, or arising out of his status as such, whether or not such person may have a right to be indemnified by the Corporation against such liability and expenses under this Article IX.

Section 8. Certain Definitions. For the purposes of this Article IX: (a) “expenses” includes, but is not limited to, fees and disbursements of legal counsel; (b) “liability” includes amounts of any judgment, fine or penalty, and reasonable amounts paid in settlement; (c) “action, suit or proceeding” (unless otherwise limited) includes every claim, action, suit or proceeding, whether civil or criminal, derivative or otherwise, administrative or investigative, and any appeal relating thereto, and any reasonable apprehension or threat of any such action, suit or proceeding; (d) references to “other enterprises” includes employee benefit plans, references to “fines” includes any excise taxes assessed on a person with respect to any employee benefit plan, references to “serving at the request of the Corporation” includes 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 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 interests of the Corporation;” (e) “Qualifying Person” means a person who was or is (i) a director of the Corporation or (ii) an officer of the Corporation or (iii) a director, officer, employee or agent of any other corporation, partnership, joint venture, trust or other enterprise at the request of the Corporation simultaneously with holding office as a director or officer of the Corporation; and (f) the termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plan of nolo contendere or its equivalent, shall not, of itself, create a presumption that the conduct of the person seeking indemnification did not meet the standard of conduct set forth in the proviso clauses of the first sentences of Sections 1 and 3 of this Article IX.
