The corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative, other than an action by or in the right of the corporation, by 7 reason of the fact that he or she is or was a director or officer of the corporation or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust, or other enterprise against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit, or proceeding if he or she acted in good faith and in a manner he or she 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, in no event shall the corporation indemnify such person against expenses, penalties, or other payments incurred in an administrative proceeding or action instituted by an appropriate regulatory agency having jurisdiction over national bank holding companies which proceeding or action results in a final order assessing civil money penalties or requiring affirmative action by such person in the form of payments to the corporation. The termination of any action, suit, 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 or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful. Section 2. The corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he or she is or was a director or officer of the corporation or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust, or other enterprise against expenses, including attorneys' fees, actually and reasonably incurred by him or her in connection with the defense or settlement of such action or suit if he or she acted in good faith and in a manner he or she 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 for any negligence or misconduct in the performance of his or her duty to the corporation unless and only to the extent that 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 circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper. Section 3. Any indemnification under Section 1 and 2 of this Article, unless ordered by a court, shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director or officer is proper in the circumstances because he or she has met the applicable standard of conduct set forth in Section 1 and 2 of this Article. Such determination shall be made 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, or if such a quorum is not obtainable, or, even if obtainable a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or by the shareholders of the corporation. 8 Section 4. Expenses incurred in defending a civil or criminal action, suit, or proceeding may be paid by the corporation in advance of the final disposition of such action, suit, or proceeding as authorized in the manner provided in Section 3 of this Article upon receipt of an undertaking by or on behalf of the director or officer to repay such amount unless it shall ultimately be determined that he or she is entitled to be indemnified by the corporation at authorized in this Article. Section 5. Nothing contained in this Article shall limit the corporation's ability to reimburse expenses incurred by a director or officer of the corporation in connection with his or her appearance as a witness in a proceeding at a time when he or she has not been made a named defendant or respondent in the proceeding. Section 6. Any indemnification of a director in accordance with this Article, including any payment or reimbursement of expenses, shall be reported in writing to the shareholders of the corporation with the notice of the next shareholders' meeting or prior to such meeting. Section 7. The corporation may purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust, or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liability under the provisions of this Article; provided, however, any such insurance shall exclude coverage for a formal order assessing civil money penalties or requiring affirmative action by such person in the form of payments to the corporation. Section 8. The indemnification provided by this Article VII (i) shall not be deemed to be exclusive of but shall be in addition to any other rights to which a person seeking indemnification hereunder may be entitled under any statute, law or agreement, or under any By-Law or resolution adopted by the board of directors or shareholders of the corporation, or otherwise, (ii) shall continue as a person who has ceased to be such director or officer and (iii) shall inure to the benefit of the heirs, legal representatives, and assigns of such person. It is the intention of the corporation to indemnify every director and officer of the corporation for liability to any person for any action taken or any failure to take any action, as a director or officer to the fullest extent permitted by law.
