(c) “Determining Body” - (i) those members of the Board who are not named as parties to the Claim for which indemnification is being sought (“Impartial Directors”), if there are at least three Impartial Directors, or (ii) a committee of at least three directors appointed by the Board (regardless whether the members of the Board of Directors voting on such appointment are Impartial Directors) and composed of Impartial Directors or (iii) if there are fewer than three Impartial Directors or if the committee appointed pursuant to clause (ii) of this paragraph so directs (regardless whether the members thereof are Impartial Directors), independent legal counsel, which may be the regular outside counsel of the Corporation.

(d) “Disbursing Officer” - the Chief Executive Officer of the Corporation or, if the Chief Executive Officer is a party to the Claim for which indemnification is being sought, any officer not a party to such Claim who is designated by the Chief Executive Officer to be the Disbursing Officer with respect to indemnification requests related to the Claim, which designation shall be made promptly after receipt of the initial request for indemnification with respect to such Claim.

(e) “Expenses” - any expenses or costs including, without limitation, attorney’s fees, judgments, punitive or exemplary damages, fines and amounts paid in settlement.

(f) “Indemnitee” - each person who is or was a director or officer of the Corporation or the spouse of such person.

11.2. Indemnity.

(a) To the extent such Expenses exceed the sum of amounts paid or due under or pursuant to (i) policies of liability insurance maintained by the Corporation, (ii) policies of liability insurance maintained by or on behalf of the Indemnitee, and (iii) provisions for indemnification in the By-laws, resolutions or other instruments of any entity other than the Corporation, the Corporation shall indemnify Indemnitee against any Expenses actually and reasonably incurred by him (as they are incurred) in connection with any Claim either against him or as to which he is involved solely as a witness or person required to give evidence, by reason of his position

(i) as a director or officer of the Corporation,

(ii) as a director or officer or any subsidiary of the Corporation or as a fiduciary with respect to any employee benefit plan of the Corporation,

(iii) as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other for profit or not for profit entity or enterprise, if such position is or was held at the request of the Corporation, or

(iv) as the spouse of any person who is or was a director or officer of the Corporation with respect to any Claim involving the spouse arising by reason of such person’s position as described in clauses (i), (ii) or (iii), whether relating to

13

service in such position before or after the effective date of this Section, if he (i) is successful in his defense of the Claim on the merits or otherwise or (ii) has been found by the Determining Body (acting in good faith) to have met the Standard of Conduct; provided that (A) the amount otherwise payable by the Corporation may be reduced by the Determining Body to such amount as it deems proper if it determines that the Claim involved the receipt of a personal benefit by Indemnitee, and (B) no indemnification shall be made in respect of any Claim as to which Indemnitee shall have been adjudged by a court of competent jurisdiction, after exhaustion of all appeals there from, to be liable for willful or intentional misconduct in the performance of his duty to the Corporation or to have obtained an improper personal benefit, unless, and only to the extent that, a court shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnity for such Expenses as the court deems proper.

(b) The Standard of Conduct is met when the conduct by an Indemnitee with respect to which a claim is asserted was conduct that he reasonably believed to be in, or not opposed to, the best interest of the Corporation, and, in the case of a criminal action or proceeding, that he had no reasonable cause to believe was unlawful. The termination of any Claim by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that Indemnitee did not meet the Standard of Conduct.

(c) Promptly upon becoming aware of the existence of any Claim as to which he may be indemnified hereunder, Indemnitee shall notify the Chief Executive Officer of the Corporation of the Claim and whether he intends to seek indemnification hereunder. If such notice indicates that Indemnitee does so intend, the Chief Executive Officer shall promptly advise the Board thereof and notify the Board that the establishment of the Determining Body with respect to the Claim will be a matter presented at the next regularly scheduled meeting of the Board. After the Determining Body has been established the Chief Executive Officer shall inform the Indemnitee thereof and Indemnitee shall immediately provide the Determining Body with all facts relevant to the Claim known to him. Within 60 days of the receipt of such information, together with such additional information as the Determining Body may request of Indemnitee, the Determining Body shall determine, and shall advise Indemnitee of is determination, whether Indemnitee has met the Standard of Conduct. The Determining Body may extend such sixty-day period by no more than an additional sixty-days.

(d) Indemnitee shall promptly inform the Determining Body upon his becoming aware of any relevant facts not therefore provided by him to the Determining Body, unless the Determining Body has obtained such facts by other means. If, after determining that the Standard of Conduct has been met, the Determining Body obtains facts of which it was not aware at the time it made such determination, the Determining Body on its own motion, after notifying the Indemnitee and providing him and opportunity to be heard, may, on the basis of such facts, revoke such determination, provided that in the absence of actual fraud by Indemnitee no such revocation may be made later than thirty days after final disposition of the Claim.

14

(e) In the case of any Claim not involving a proposed, threatened or pending criminal proceeding,

(i) If Indemnitee has, in the good faith judgment of the Determining Body, met the standard of Conduct, the Corporation may, in it sole discretion after notice to Indemnitee, assume all responsibility for the defense of the Claim, and, in any event, the Corporation and the Indemnitee each shall keep the other informed as to the progress of the defense, including prompt disclosure of any proposals for settlement; provided that if the Corporation is a party to the Claim and Indemnitee reasonably determines that there is a conflict between the positions of the Corporation and Indemnitee with respect to the Claim, then Indemnitee shall be entitled to conduct his defense, with counsel of his choice; and provided further that Indemnitee shall in any event be entitled at his expense to employ counsel chosen by him to participate in the defense of the Claim; and

(ii) The Corporation shall fairly consider any proposals by Indemnitee for settlement of the Claim. If the Corporation (A) proposes a settlement acceptable to the person asserting the Claim, or (B) believes a settlement proposed by the person asserting the Claim should be accepted, it shall inform Indemnitee of the terms thereof and shall fix a reasonable date by which Indemnitee shall respond. If Indemnitee agrees to such terms, he shall execute such documents as shall be necessary to effect the settlement. If he does not agree may proceed with the defense of the Claim in any manner he chooses, but if he is not successful on the merits or otherwise, the Corporation’s obligation to indemnify him for any Expenses incurred following his disagreement shall be limited to the lesser of (A) the total Expenses incurred by him following his decision not to agree to such proposed settlement or (B) the amount the Corporation would have paid pursuant to the terms of the proposed settlement. If, however, the proposed settlement would impose upon Indemnitee any requirement to act or refrain from acting that would materially interfere with the conduct of his affairs, Indemnitee may refuse such settlement and proceed with the defense of the Claim, if he so desires, at the Corporation’s expense without regard to the limitations imposed by the preceding sentence. In no event, however, shall the Corporation be obligated to indemnify Indemnitee for any amount paid in a settlement that the Corporation has not approved.

(f) In the case of a Claim involving a proposed, threatened or pending criminal proceeding, Indemnitee shall be entitled to conduct the defense of the Claim, and to make all decisions with respect thereto, with counsel of his choice; provided that the Corporation shall not be obligated to indemnify Indemnitee for an amount paid in settlement that the Corporation has not approved.

(g) After notifying the Corporation of the existence of a Claim, Indemnitee may from time to time request the Corporation to pay the Expenses (other than judgments, fines, penalties or amounts paid in settlement) that he incurs in pursuing a defense of the Claim prior to the time that the Determining Body determines whether the Standard of Conduct has been met.

15

If the Disbursing Officer believes the amount requested to be reasonable, he shall pay to Indemnitee the amount requested (regardless of Indemnitee’s apparent ability to repay such amount) upon receipt of an undertaking by or on behalf of Indemnitee to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation under the circumstances. If the Disbursing Officer does not believe such amount to be reasonable, the Corporation shall pay the amount deemed by him to be reasonable and Indemnitee may apply directly to the Determining Body for the remainder of the amount requested.

(h) After it has been determined that the Standard of Conduct was met, for so long and to the extent that the Corporation is required to indemnify Indemnitee under this Agreement, the provisions of Paragraph (g) shall continue to apply with respect to Expenses incurred after such time except that (i) no undertaking shall be required of Indemnitee and (ii) the Disbursing Officer shall pay to Indemnitee such amount of any fines, penalties or judgments against him which have become final as the Corporation is obligated to indemnify him.

(i) Any determination by the Corporation with respect to settlements of a Claim shall be made by the Determining Body.

(j) The Corporation and Indemnitee shall keep confidential, to the extent permitted by law and their fiduciary obligations, all facts and determinations provided or made pursuant to or arising out of the operation of this Agreement, and the Corporation and Indemnitee shall instruct it or his agents and employees to do likewise.

11.3. Enforcement.

(a) The rights provided by this Section shall be enforceable by Indemnitee in any court of competent jurisdiction.

(b) If Indemnitee seeks a judicial adjudication of his rights under this Section, Indemnitee shall be entitled to recover from the Corporation, and shall be indemnified by the Corporation against, any and all Expenses actually and reasonably incurred by him in connection with such proceeding but only if he prevails therein. If it shall be determined that Indemnitee is entitled to receive part but not all of the relief sought, then the Indemnitee shall be entitled to be reimbursed for all Expenses incurred by him in connection with such judicial adjudication if the amount to which he is determined to be entitled exceeds 50% of the amount of his Claim. Otherwise, the Expenses incurred by Indemnitee in connection with such judicial adjudication shall be appropriately prorated.

(c) In any judicial proceeding described in this subsection, the Corporation shall bear the burden of proving that Indemnitee is not entitled to any Expenses sought with respect to any Claim.

11.4. Saving Clause. If any provision of this Section is determined by a court having jurisdiction over the matter to require the Corporation to do or refrain from doing any act that is in violation of applicable law, the court shall be empowered to modify or reform such provision so that, as modified or reformed, such provision provides the maximum indemnification

16

permitted by law, and such provision, as so modified or reformed, and the balance of this Section, shall be applied in accordance with their terms. Without limiting the generality of the foregoing, if any portion of this Section shall be invalidated on any ground, the Corporation shall nevertheless indemnify an Indemnitee to the full extent permitted by any applicable portion of this Section that shall not have been invalidated and to the full extent permitted by law with respect to that portion that has been invalidated.

11.5. Non-Exclusivity.

(a) The indemnification and advancement of Expenses provided by or granted pursuant to this Section shall not be deemed exclusive of any other rights to which Indemnitee is or may become entitled under any statute, article of incorporation, by-law, authorization of shareholders or directors, agreement, or otherwise.

(b) It is the intent of the Corporation by this Section to indemnify and hold harmless Indemnitee to the fullest extent permitted by law, so that if applicable law would permit the Corporation to provide broader indemnification rights than are currently permitted, the Corporation shall indemnify and hold harmless Indemnitee to the fullest extent permitted by applicable law notwithstanding that the other terms of this Section would provide for lesser indemnification.

11.6. Successors and Assigns. This Section shall be binding upon the Corporation, its successors and assigns, and shall inure to the benefit of the Indemnitee’s heirs, personal representatives, and assigns and to the benefit of the Corporation, its successors and assigns.

11.7. Indemnification of Other Persons.

(a) The Corporation may indemnify and person not covered by Sections 11.1 through 11.6 to the extent provided in a resolution of the Board or a separate Section of these By-laws.

(b) Section 11 of these By-laws as in effect immediately prior to the adoption of this Section 11.7 shall remain in effect with respect to persons not covered by Section 11.1 through 11.6 to the extent necessary to satisfy the Corporation’s contractual obligations entered into prior to such date to provide indemnification to directors and officers of corporations or banks acquired by the Corporation.

(c) Nothing in this Section 11 shall obligate the Corporation to indemnify or advance expenses to any person who was a director, officer or agent of any corporation merged into this Corporation or otherwise acquired by this Corporation. Any such person’s right to indemnification or advancement of expenses, if any, shall consist of those rights contained in the agreement relating to such merger or acquisition.
