Each person who was or is made a party or is threatened to be made a party to or is otherwise involved (including, without limitation, as a witness) in any actual or threatened action, claim, suit investigation or proceeding, of any nature whatsoever (hereinafter “proceeding”), by reason of the fact that he or she is or was a director, board member, committee member, partner, trustee, officer or employee of any foreign or domestic organization or any separate investment account, or any individual who serves in any capacity with respect to any employee benefit plan, or that, being or having been such a director, board member, committee member, partner, trustee, officer or employee of any foreign or domestic organization or any separate investment account or any individual who serves in any capacity with respect to any employee benefit plan, he or she is or was serving at the request of an executive officer of the Corporation as a director, board member, committee member, partner, trustee, officer, employee or agent of another corporation or of a partnership, joint venture, trust, limited liability company or other enterprise, including service with respect to an employee benefit plan (hereinafter an “indemnitee”), whenever the basis of such proceeding is alleged action in an official capacity as such shall be indemnified and held harmless by the Corporation to the fullest extent permitted by

law, as the same exists or may hereinafter 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 permitted prior thereto), or by other applicable law as then in effect, against all costs and reasonable counsel fees, fines, penalties, judgments or awards of any kind, and the amount of reasonable settlements, whether or not payable to the Corporation or to any of the other entities described above actually incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased to be a director, board member, committee member, partner, trustee, officer or employee of any foreign or domestic organization or any separate investment account or any individual who serves in any capacity with respect to any employee benefit plan and shall inure to the benefit of the indemnitee’s heirs, executors, legal representatives and administrators. To the extent any of the indemnification provisions set forth above prove to be ineffective for any reason in furnishing the indemnification provided, each of the persons named above shall be indemnified by the Corporation to the fullest extent not prohibited by applicable law.

Notwithstanding the foregoing, no indemnification shall be provided with respect to:

1. any matter as to which the person shall have been adjudicated in any proceeding not to have acted in good faith in the reasonable belief that his or her action was in the best interests of the Corporation or, to the extent that such matter relates to service with respect to any employee benefit plan, in the best interests of the participants or beneficiaries of such employee benefit plan;

2. any liability to any entity which is registered as an investment company under the Federal Investment Company Act of 1940 or to the security holders thereof, where the basis for such liability is willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the office; and

3. any action, claim or proceeding voluntarily initiated by any person seeking indemnification, unless such action, claim or proceeding had been authorized by the Board or unless such person’s indemnification is awarded by vote of the Board.

In any matter disposed of by settlement or in the event of an adjudication which in the opinion of the General Counsel or his or her delegate does not make a sufficient determination of conduct which could preclude or permit indemnification in accordance with the preceding paragraphs, the person shall be entitled to indemnification unless, as determined by the majority of the disinterested directors or in the opinion of counsel (who may be an officer of the Corporation or outside counsel employed by the Corporation), such person’s conduct was such as precludes indemnification under any such paragraph. The termination of any action, claim, suit, investigation or proceeding by judgment, order, settlement, 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 he or she reasonably believed to be in the best interests of the Corporation.

1.1 Advancements. The Corporation may at its option indemnify for expenses incurred in connection with any action or proceeding in advance of its final disposition, upon receipt of a satisfactory undertaking for repayment if it be subsequently determined that the person thus indemnified is not entitled to indemnification under this Article VII.
