The Secretary shall file such consents in the minute book of the Corporation.

Section 6. List of Shareholders. At least ten (10) days before each meeting of shareholders the Secretary shall cause to be prepared a complete list of the names and addresses of all shareholders entitled to vote at such meeting, arranged in alphabetical order, with the number of shares held by each, and such list shall be produced and kept at the registered Missouri office and shall be subject to inspection by any shareholder during regular business hours.

Directors

Section 1. Qualifications. The corporate powers, business and property of the Corporation shall be exercised, conducted and controlled by the Board of Directors. It shall not be necessary for a director to be a shareholder. The Corporation will take all reasonable efforts to comply with applicable requirements of the Securities and Exchange Commission, any self-regulatory organization having requirements applicable to the Corporation, and other applicable legal and regulatory requirements, including but not limited to the requirement that at least a majority of the members of the Board qualify as “independent directors” as such term is defined and described in the aforesaid requirements and as determined by the Board from time to time.

Section 2. Directors - Number. The Board of Directors shall consist of not less than eight (8) nor more than eighteen (18) members, with the exact number to be set from time to time by the Board. Commencing with the annual meeting of shareholders in 2012, each director shall hold office until the next succeeding annual meeting or until such director’s successor is duly elected and qualified, unless such director shall sooner die, resign or be removed or disqualified; provided however, that any director serving as of July 26, 2011, who had been prior to that date elected by the shareholders to a term expiring after the date of the 2012 annual meeting, shall continue to serve until the end of such term, unless such director shall sooner die, resign or be removed or disqualified.

Section 3. Election of Directors; Terms; Removals; Vacancies. Each director shall hold office for the term for which he/she is elected in accordance with these By-Laws, and until his/her successor is elected and qualified or until his/her earlier death, resignation or removal. The entire Board or any one or more directors may be removed with or without cause if (1) at a meeting specially called for the purpose of removing directors, the holders of at least two-thirds of the outstanding shares of stock then entitled to vote in elections of directors shall vote for such removal, and (2) as to any director, the number of shares voted against removal would not be sufficient to elect him if then cumulatively voted in an election of the entire Board of Directors. If the office of any director is vacant by reason of death, resignation, removal or increase in the number of authorized directors due to amendment of the By-Laws, the Corporate Governance & Nominating Committee may select and approve, and a majority of the other directors (though less than a quorum) may appoint, a director to fill the vacancy until a successor shall have been duly elected at a shareholders meeting, which election shall be not later than the next regularly scheduled annual meeting of the shareholders

Section 4. Annual Meeting. The annual meeting of the directors for the purpose of electing officers and transacting such other business as may come before the meeting shall be held on the same day as the annual meeting of the shareholders, following the final adjournment of the annual meeting of shareholders on that day. In the event the annual meeting of shareholders is continued, recessed or adjourned from day to day, or from time to time, then in such event the annual meeting of the directors shall be held immediately following the final adjournment of the annual meeting of shareholders.

The Secretary of the Corporation shall give notice of all special meetings of the directors by delivering to each director in person not later than the day prior to the meeting, or as to any such director not so personally notified by mailing to him, a written or printed notice of such meeting, postage prepaid, or by telegraph, confirmed facsimile transmission, electronic mail or other means of electronic transmission to the address, number, email account or other reference supplied by such director for the purpose of receiving such communication, or by messenger delivery to each such director, at his last known address, so that in the ordinary course of the method of delivery it would reach such director at least on the day prior to the meeting. The business transacted at all special meetings of directors shall be confined to the subjects stated in the notice and to matters germane thereto, unless all directors of the Corporation are present at such meeting and consent to the transaction of other business.

Such waiver may be by signed facsimile transmission, telegram, or electronic transmission.

Any such Lead Director shall serve in that capacity for a term of one year (and may be re-elected annually by a majority vote of the Independent Directors for one or more additional one-year terms), or until such earlier time as (i) he/she ceases to qualify as an Independent Director, or (ii) the Independent Directors appoint a different Independent Director as Lead Director. The Board shall make a determination of which of the Company’s Directors qualify as an Independent Director, such determination to be made at least annually, and on a more frequent basis if a new Director is elected or if there are changes in the circumstances of an existing Director that may affect his/her ability to continue to qualify as an Independent Director.

Absent action by the Board of Directors, the fiscal year of the Corporation shall begin on the first day of January in each calendar year and shall terminate on the last day of December of the same calendar year.

Section 2. Failure or Refusal to Give Notice Upon Request. If the Secretary, upon written request by the proper party or parties as permitted and provided in these By-Laws, shall fail or refuse to give any notice which he is required to give in accordance with the provisions hereof, the party or parties entitled to require that such notice be given may sign and issue a notice of the character and in the manner herein provided and setting forth in such notice the fact of such failure or refusal on the part of the Secretary to give the notice as requested; and such notice so signed and issued shall have the same force and effect as though signed and issued by the Secretary of the Corporation.

Section 4. Indemnification of Directors and Officers.

1. 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 reason of the fact that he or she is or was a director or officer of the Corporation or any of its subsidiaries (a subsidiary is defined as another corporation included in a controlled group of corporations of which the Corporation is a common parent), 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 (which shall be deemed to include service in a fiduciary capacity or otherwise with respect to any employee benefit plan of the Corporation or any other corporation) shall, to the maximum extent permitted by applicable law, be indemnified against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement (which shall include any excise taxes assessed against a person with respect to an employee benefit plan) 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 or the participants or beneficiaries of any employee benefit plan, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Any employee of the Corporation or its subsidiaries, when acting in a supervisory or managerial capacity, may likewise be indemnified, but such indemnification is not mandatory. 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 interest of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

2. 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 shall, to the maximum extent permitted by applicable law, be indemnified against expenses (including attorneys’ fees) and amounts paid in settlement actually and reasonably incurred by him or her in connection with the defense or settlement of the 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. Any

10

employee of the Corporation or its subsidiaries, when acting in a supervisory or managerial capacity, may likewise be indemnified, but such indemnification is not mandatory. However, no indemnification shall be made in respect of any claim, issue or matter as to which any person shall have been adjudged to be liable for negligence or misconduct in the performance of his or her duty to the Corporation unless and only to the extent that a court determines that, despite the adjudication of liability and in view of all the circumstances of the case, that the person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

3. Except as may otherwise be provided in the Corporation’s By-Laws, any person who has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Sections 1 or 2 above, shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith.

4. Except as provided in Section 5, indemnification of anyone under Sections 1 or 2, unless ordered by a court, shall be made by the Corporation only as authorized in each case upon a determination that it is proper because the director, officer or employee has met the applicable standard of conduct set forth. Such a determination shall be made by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to the 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.

5. Notwithstanding anything herein to the contrary, no director, officer or employee shall be indemnified against any expenses, penalties or other payments incurred:

a. In an administrative proceeding or action instituted by a bank regulatory agency to the extent that such indemnification would constitute a “prohibited indemnification payment” (as such term is defined under applicable provisions of the Federal Deposit Insurance Act and regulations thereunder, as amended from time to time) except under circumstances specifically permitted by such Act and regulations, or that would otherwise constitute an indemnification payment that is prohibited by applicable provisions of law or regulations, or

b. Unless he or she notifies the Corporation in writing of the threatened, pending or completed action, suit, proceeding or investigation promptly on becoming aware thereof and, before incurring expense of any kind therein or in connection therewith, gives the Corporation or its insurer the opportunity to provide an independent attorney to represent him or her in, and to otherwise counsel him or her in connection with, any such action, suit, proceeding or investigation, or

c. For or with respect to any amount paid to settle a claim asserted or action, suit or proceeding brought or threatened against him or her unless the Corporation’s board of directors (1) approved the amount of such settlement as (A) reasonable and (b) not affecting the institution’s safety and soundness, or (2) could not, by reason of the action, intervention or threat of a court, government agency or instrumentality, act with complete independence and free of circumscription in relation to the subject matter, or

d. For or with respect to any claim made against him or her for an accounting of profits made from the purchase or sale by him or her of securities of the Corporation within the meaning of Section 16b of the Securities Exchange Act of 1934 and amendments thereto or similar provisions of any statutory law or common law, or

e. In connection with any action, suit or proceeding (or part thereof) initiated by such person claiming indemnification unless such action, suit or proceeding (or part thereof) initiated by such person was authorized by the board of directors of the Corporation.

11

6. The right to indemnification of officers and directors shall include the right, to the extent permissible under applicable provisions of law and regulations, to be paid by the Corporation reasonable expenses, including attorney’s fees (but not including any retainers or pre-payments of fees, unless such retainers or pre-payments are approved by the Board), incurred in defending any such action, suit or proceeding, in advance of its final disposition; provided, however, that the payment of such expenses in advance of the final disposition of such proceeding shall be made only:

a. upon delivery to the Corporation of a written agreement, by or on behalf of such director or officer, in which such director or officer agrees to repay all amounts so advanced if it should be ultimately determined by a court or other tribunal or by the board of directors, that (1) such person is not entitled to be indemnified under this Section or otherwise or (2) that such director or officer is assessed a civil money penalty imposed by a bank regulatory agency, is removed or prohibited from banking or is required under a final order to cease an action or take an affirmative action by a bank regulatory agency, and

b. until such time as the Board of Directors has made a final determination regarding indemnification under paragraph 4 above. If the Board of Directors’ final determination is that indemnification is not proper, then further advancement of expenses, including attorney’s fees, will immediately cease. If however the Board of Directors’ final determination is that indemnification is proper, then indemnification of expenses, including attorney’s fees, will continue.

7. Right of Claimant to Bring Suit.

a. If the claim of an officer or director for indemnification payments due to him/her under the provisions of these By Laws is not paid in full by the Corporation within thirty days after a written claim therefore has been received by the Corporation, the claimant may any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim.

b. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its shareholders) to have made a determination prior to the commencement of such action that the claimant is entitled to indemnification or advancement under the circumstances, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its shareholders) that the claimant is not entitled to indemnification or advancement, shall be a defense to the action or create a presumption that the claimant is not entitled to indemnification or advancement.

8. The Corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer or employee of the Corporation or any of its subsidiaries or is or was serving at the request of the Corporation as a director, officer or employee 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 the By Laws or applicable provisions of law, provided that such insurance shall not provide coverage inconsistent with that permitted by applicable statutes, rules and regulations.

9. The indemnification provided for directors, officers or employees of the Corporation shall not be deemed exclusive of any other rights to which those officers, directors or employees may be entitled under any By-law, agreement, vote of shareholders or disinterested directors or otherwise, both as to actions in his or her official capacity and as to actions in another capacity while holding such office, and shall continue as to any person who has ceased to be a director, officer or employee of the Corporation and shall inure to the benefit of his or her heirs, executors and administrators.

12

10. The right to be indemnified or to the reimbursement or advancement of expenses of officers and directors pursuant hereto:

a. is a contract right based upon good and valuable consideration, pursuant to which the person entitled thereto may bring suit as if the provisions hereof were set forth in a separate written contract between the Corporation and the director or officer,

b. is intended to be retroactive and shall be available with respect to events occurring prior to the adoption hereof, and,

c. shall continue to exist after the rescission or restrictive modification hereof with respect to events occurring prior thereto.

Section 5. Amendments to By-Laws. The Board of Directors shall have the power to make, alter, amend or repeal the By-Laws of this Corporation from time to time.
