Unless a determination has been made that indemnification is not permissible, the Corporation shall make advances and reimbursements for expenses incurred by a director or officer in a proceeding upon receipt of an undertaking from him to repay the same if it is ultimately determined that he is not entitled to indemnification. Such undertaking shall be an unlimited, unsecured general obligation of the director or officer and shall be accepted without reference to his ability to make repayment. The Board of Directors is hereby empowered, by majority vote of a quorum of disinterested directors, to contract in advance to indemnify and advance the expenses of any director or officer. C. Permissive Indemnification. The Board of Directors is hereby empowered, by majority vote of a quorum of disinterested directors, to cause the Corporation to indemnify or contract in advance to indemnify any person not specified in Section B of this Article IX who was or is a party to any proceeding, by reason of the fact that he is or was an employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other profit or nonprofit enterprise, to the same extent as if such person was specified as one to whom indemnification is granted in Section B. D. Insurance. The Corporation may purchase and maintain insurance to indemnify it against the whole or any portion of the liability assumed by it in accordance with this Article IX and may also procure insurance, in such amounts as the Board of Directors may determine, 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 the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other profit or non-profit enterprise, against any liability asserted against or incurred by such person in any such capacity or arising from his status as such, whether or not the Corporation would have power to indemnify him against such liability under the provisions of this Article IX. E. Special Legal Counsel. In the event there has been a change in the composition of a majority of the Board of Directors after the date of the alleged act or omission with respect to which indemnification is claimed, any determination as to indemnification and advancement of expenses with respect to any claim for indemnification made pursuant to Section B of this Article IX shall be made by special legal counsel agreed upon by the Board of Directors and the proposed indemnitee. If the Board of Directors and the proposed indemnitee -6- are unable to agree upon such special legal counsel, the Board of Directors and the proposed indemnitee each shall select a nominee, and the nominees shall select such special legal counsel. F. Indemnitee's Rights. The provisions of this Article IX shall be applicable to all actions, claims, suits or proceedings commenced after the adoption hereof, whether arising from any action taken or failure to act before or after such adoption. No amendment, modification or repeal of this Article IX shall diminish the rights provided hereby or diminish the right to indemnification with respect to any claim, issue or matter in any other pending or subsequent proceeding that is based in any material respect on any alleged action or failure to act prior to such amendment, modification or repeal. G. Additional Indemnitees.
