Special meetings of the shareholders may be called at any time by the Chair of the Board, or in the case of the absence or disability of the Chair, by any Chief Executive Officer or the President, or at any time upon the written request of a majority of the Board, or upon the written request of the holders of not less than one-fifth of the outstanding stock of the Corporation entitled to vote at such meeting.

annual meeting, the notice shall state that the purposes thereof are the election of directors and the transaction of such other business as may properly come before the meeting according to the Articles of Incorporation and Section 12 of Article II of these Bylaws. In the case of a special meeting, such notice shall state the purpose or purposes for which the meeting is called.

Any notice of a shareholders’ meeting sent by facsimile or electronic transmission shall be deemed to be delivered at the time it is delivered to the address, number, email account, or other reference supplied by the recipient for the purpose of receiving such communications.

Section 4. Waiver of Notice.

A copy of such waiver shall be entered in the minutes and shall be deemed to be the notice required by applicable law, the Articles of Incorporation, or these Bylaws. Any shareholder present in person, or represented by proxy, at any meeting of the shareholders shall be deemed to have thereby waived notice of such meeting except where such attendance is for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened.

Section 5. Actions Without a Meeting. Any action which is required to be taken, or may be taken, at a meeting of the shareholders may be taken without a meeting if consents in writing, setting forth the action so taken, shall be signed by all of the shareholders entitled to vote with respect to the subject matter thereof. Such consents shall have the same force and effect as a unanimous vote of the shareholders at a meeting duly held, in accordance with Section 351.273 of The General and Business Corporation Law of Missouri. The Secretary shall file such consents with the minutes of the meetings of the shareholders.

Section 6. List of Shareholders. At least ten (10) days before each meeting of the 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 based on the Corporation’s stock transfer books, arranged in alphabetical order, with the number of shares held by each, and such list shall be produced and kept for a period of ten (10) days prior to the meeting at the registered office of the Corporation in the State of Missouri and shall be subject to inspection by any shareholder during usual business hours. Such list shall also be produced and kept open at the meeting and shall be subject to inspection by any shareholder during the meeting.

Section 7. Quorum. At any meeting of the shareholders, a majority of the outstanding shares of stock entitled to vote at such meeting, being represented in person or by proxy, shall constitute a quorum for all purposes, including the election of directors, except as otherwise required by applicable law. Shares represented by a proxy which directs that the shares abstain from voting or that a vote be withheld on a matter, shall be deemed to be represented at the meeting for quorum purposes. Shares as to which voting instructions are given as to at least one of the matters to be voted on shall also be deemed to be so represented. If the proxy states how shares will be voted in the absence of instructions by the shareholder, such shares shall be deemed to be represented at the meeting.

Page 2 of 16

Section 8. Organization. The Chair of the Board, or in the case of the absence or disability of the Chair, any Chief Executive Officer or the President shall preside at each meeting of the shareholders. The Secretary, or in the case of the absence or disability of the Secretary, an Assistant Secretary or a secretary pro tem shall act as secretary of all meetings of the shareholders.

Section 9. Voting. At each meeting of the shareholders, each shareholder shall be entitled to vote in person, or by proxy made in accordance with the provisions of the Articles of Incorporation and these Bylaws and held by some person or persons present at such meeting, upon all matters presented at the meeting. With the exception of the election of directors, each shareholder shall have one vote for each share of stock standing in his or her name on the books of the Corporation on the record date determined as provided in Section 6 of Article VII of these Bylaws, except as otherwise provided by applicable law. In the election of directors, except as otherwise provided by applicable law, each shareholder shall have the right to cast as many votes in the aggregate as shall equal the number of shares held by him or her multiplied by the number of directors to be elected at such election, and said votes may be cast for one director candidate or distributed among two or more director candidates. If any director candidate nominated by the Board unexpectedly becomes unavailable prior to the election, the shares represented by proxy and voting for that candidate will be voted instead for a substitute candidate nominated by the Board. In any matter other than the election of directors, every decision of a majority of the shares cast at a meeting at which a quorum is present shall be valid as an act of the shareholders, unless a larger vote is required by The General and Business Corporation Law of Missouri, the Articles of Incorporation, or these Bylaws. Directors shall be elected by a plurality of the votes of the shares entitled to vote on the election of the directors and represented in person or by proxy at a meeting at which a quorum is present. If voting shall be by ballot for the election of directors or other questions, the presider of such meeting of the shareholders may appoint not less than two (2) persons, who are not directors or candidates for the election as a director, to act as Inspectors of Election and to receive and canvass the votes cast at such meeting and certify the results to the presider. Each such Inspector, before entering upon the discharge of his or her duties, shall take and subscribe any oath required by The General and Business Corporation Law of Missouri. The Inspectors of Election shall take care of the polls and after the balloting shall make and file a written certificate of the result of the votes cast at the meeting.

Section 10. Adjournment. If, at any meeting of the shareholders, a quorum shall fail to attend at the time and place for which such meeting was called, or if the business of such meeting shall not be completed, the meeting may be successively adjourned from day to day, or from time to time, not exceeding ninety (90) days from such adjournment, without further notice, until a quorum shall attend or the business thereof shall be completed. Such adjournment and the reasons therefor shall be recorded with the minutes of the meetings of the shareholders. At any such adjourned meeting, any business may be transacted which might have been transacted at the meeting as originally called.

Section 11. Proxies. Proxies must either (a) be in writing, signed by the shareholder or his or her duly authorized attorney-in-fact or legal representative and filed with the Secretary, or (b) be sent by electronic means or by telephone to the Secretary through a system that is designed to (i) enable the Secretary to verify that the transmission was authorized by the shareholder, and (ii) enable the recipient to retain, retrieve, and reproduce the information authorized by the shareholder. Unless specified therein that it is irrevocable, any proxy may be revoked at the pleasure of the person executing it (A) by a writing signed by the shareholder or his or her duly authorized attorney-in-fact or legal representative and filed with the Secretary or (B) by notice given by electronic means or by

Page 3 of 16

telephone to the Secretary through a system of a kind described in the preceding sentence. To be effective the grant of a proxy or the revocation of a proxy must be manually signed and filed with the Secretary at or before the roll call of the meeting at which the same is to be used or must be delivered by electronic means or by telephone to the Secretary within the time period specified by the Secretary in advance of the meeting. The Secretary, in his or her sole discretion, may designate the Corporation’s transfer agent or other proxy tabulator to receive grants or revocations of proxies for any of these purposes. No proxy shall be valid after the expiration of eleven (11) months from its date of execution, unless otherwise provided in the proxy. In the event that a proxy shall designate two or more persons to act as proxies, a majority of such persons present at the meeting, or, if only one shall be present, then that one, shall have and may exercise all of the powers conferred by such proxy upon all of the persons so designated, unless the proxy shall otherwise provide.

Page 5 of 16

Section 3. Nomination. The Corporate Governance & Nominating Committee (the “Governance Committee”) of the Board will recommend, and the Board will nominate, a slate of director candidates for election to the Board at each annual meeting of the shareholders. The Governance Committee must consider potential director candidates who are recommended by shareholders in compliance with applicable law. Any recommendation by shareholders to the Governance Committee must include the information described in Section 12(d) of Article II of these Bylaws and must be submitted in writing to the Chair of the Governance Committee at the principal office of the Corporation.

Section 4. Election, Vacancies, and Removal. At each annual meeting of the shareholders, shareholders entitled to vote in the election of directors at the meeting will elect directors as provided by applicable law, the Articles of Incorporation, and these Bylaws. If for any reason the election of directors cannot be held during an annual meeting, the election may be held on any other day at a special meeting of the shareholders called and held for that purpose. The Chair of the Board will be appointed by the Board from among its members. Vacancies on the Board and newly created directorships resulting from any increase in the number of directors to constitute the Board may be filled by a majority of the directors then in office, although less than a quorum, or by a sole remaining director, until the next election of directors by the shareholders. A director may resign by notice to the Board, the Chair of the Board, or the Secretary, and whether or not accepted, such a resignation will become effective on the later of the date of receipt or the date of resignation specified in the notice. The entire Board or any one or more of the directors may be removed with or without cause if (a) 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 (b) as to any director if less than the entire Board is to be removed, the number of shares voted against removal would not be sufficient to elect the director if then cumulatively voted in an election of the entire Board. In addition, any director may be removed for cause by action of a majority of the entire Board if the director to be removed shall, at the time of removal, fail to meet the qualifications for election as a director stated in the Articles of Incorporation or these Bylaws or shall be in breach of any agreement between such director and the Corporation relating to such director’s services as a director or employee of the Corporation. Notice of the proposed removal of a director by the Board shall be given to all directors of the Corporation prior to action thereon.

Section 5. Regular Meetings. Regular meetings of the Board may be held at such time and place as shall be determined from time to time by the Board. After the time and place of any such regular meeting shall have been so determined, no notice of such regular meeting need be given. Independent directors (as defined in the Corporate Governance Guidelines of the Corporation and subject to any additional independence criteria established by the Board, NASDAQ Stock Market Listing Rule 5605(a)(2), and Rule 10A-3 under the Exchange Act, the “Independent Directors”) shall convene regularly scheduled executive sessions at least twice per year in conjunction with regularly scheduled Board meetings or at such other times and places as deemed necessary or appropriate by the Independent Directors or as required by applicable law.

Section 6. Special Meetings. Special meetings of the Board for any purpose or purposes may be called by the Chair of the Board, or in the case of the absence or disability of the Chair, by any Chief

Page 6 of 16

Each call for a special meeting of the Board must state the time, the day, the place, and the purpose or purposes of the meeting and must be delivered to the Secretary.

Section 7. Notice of Meetings. No notice shall be required to be given of any regular meeting of the Board. Notice of any change in the time or place of any regular meeting and notice of any special meeting, in each case, shall be given within a reasonable time in advance of the meeting to each director in person or by mail, courier, telephone, confirmed facsimile transmission, electronic mail, or other means of electronic transmission to the address, number, e-mail account, or other reference supplied by such director for the purpose of receiving communications. A notice of a special meeting will include the purpose or purposes of the meeting. Attendance of a director at any meeting of the Board will constitute a waiver of notice of the meeting, except where a director attends a meeting for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened. Notice of a meeting of the Board may also be waived by a director in writing, by signed facsimile transmission, or by electronic mail or other electronic transmission.

Section 8. Actions Without a Meeting. Any action that is required to be or may be taken at a meeting of the Board may be taken without a meeting if, setting forth the action so taken, all of the members of the Board consent to the action in writing or by electronic transmission. Such a consent has the same force and effect as a unanimous vote at a meeting duly held. The Secretary must file the consents with the minutes of the meetings of the Board.

Section 9. Quorum. A majority of the Board constitutes a quorum for the transaction of business, and the act of a majority of the directors present at a meeting at which a quorum is present shall be the act of the Board, except to the extent otherwise required by applicable law, the Articles of Incorporation, or these Bylaws.

Section 10. Adjournment. If at any meeting of the Board a quorum shall fail to attend, a majority of the directors present at the time and place appointed for such meeting may adjourn the meeting from time to time to any time and place until the next regular meeting of the Board, without notice other than an oral announcement at the meeting and adjournments thereof, until a quorum shall attend. Likewise, any meeting of the Board at which a quorum is present may also be adjourned, in like manner and on like notice, for such time or upon such call as may be determined by a majority of the directors there present. At any such adjourned meeting at which a quorum shall be present, any business may be transacted which might have been transacted at the meeting as originally called.

Section 11. Organization. The Chair of the Board, or the Lead Director (if a Lead Director has been appointed) in the case of the absence or disability of the Chair, or a chair pro tem selected by a majority of the directors present in the case of the absence or disability of all of them, shall preside at any meeting of the Board. The Secretary, or an Assistant Secretary in the case of the absence or disability of the Secretary, or a secretary selected by the presider in the case of the absence or disability of all of them, shall act as the secretary of any meeting of the Board. Members of the Board may attend and participate in a meeting through a telephonic or video conference call or through the use of similar communications equipment, in each case, where all persons participating in the meeting can hear each other, and participation in a meeting in this manner will constitute presence in person at the meeting.

Section 13. Minutes. The Board shall cause to be kept a complete record of its meetings and acts and of the proceedings of the shareholders.

Section 14. Powers of the Board. In addition to the powers and authorities conferred by applicable law, the Articles of Incorporation, and these Bylaws, the Board may exercise all such powers and authorities of the Corporation and do all such lawful acts and things as are not by law prohibited and are not required or directed to be exercised or done by the shareholders.

Section 15. Compensation of Directors. The compensation to be paid to the directors shall be determined from time to time by the Board, based upon the recommendations of the Compensation Committee, but no such compensation for service as a director may be paid to any director who shall at the time be receiving a salary from the Corporation or any of its subsidiaries as an officer thereof.

Section 16. Lead Director. At any time when the Chair of the Board does not qualify as an Independent Director, the Independent Directors shall, by a majority vote at a meeting consisting solely of Independent Directors, appoint one of the Independent Directors as Lead Director. The Lead Director shall have the following authority and responsibilities: (a) to preside at meetings of the full Board, if the Chair is not present; (b) to convene periodic meetings of Independent Directors (at which only Independent Directors are present) and preside over such meetings; (c) to approve agendas for Board meetings and information to be sent to the Board; (d) to approve schedules of Board meetings, to assure there is sufficient time to discuss all agenda items; (e) to serve as a liaison between the Independent Directors and the Chair; (f) to hold periodic meetings with the Chief Executive Officer and Chair to discuss matters of importance to the Independent Directors, act as the Independent Directors’ informal spokesperson, and help facilitate the Board’s oversight of management; (g) to serve as an advocate for the interests of the Corporation’s shareholders; (h) if requested by major shareholders of the Corporation, to ensure that the Lead Director is available for consultation and direct communications; and (i) to coordinate the activities of the other Independent Directors and perform such other duties and responsibilities as a majority of the Independent Directors may specify from time to time.

In case any certificate shall be claimed to be lost, destroyed, or wrongfully taken, no new or duplicate certificate shall be issued for the shares represented thereby and no new certificate shall be issued upon a transfer of such shares, except pursuant to a judgment of a court of competent jurisdiction, duly given and made in accordance with the laws of the State of Missouri, or upon a corporate surety bond or other indemnity in form and amount satisfactory to the Corporation being furnished to the Corporation and other provisions of applicable law being satisfied.

Page 11 of 16

days preceding the date of any meeting of the shareholders or the date of payment of any dividend or the date for the allotment of rights or the date when any change, conversion, or exchange of shares shall go into effect; provided, however, that in lieu of closing the stock transfer books, the Board may fix in advance a date, not exceeding seventy (70) days preceding the date of any meeting of the shareholders or the date for the payment of any dividend or the date for the allotment of rights or the date when any change, conversion, or exchange of shares shall go into effect, as a record date for the determination of the shareholders entitled to notice of, and to vote at, such meeting, and any adjournment or postponement thereof, or entitled to receive payment of such dividend, or entitled to such allotment of rights, or entitled to exercise the rights in respect of such change, conversion, or exchange of shares. In such case only the shareholders who are shareholders of record on the date of closing the stock transfer books or on the record date so fixed shall be entitled to notice of, and to vote at, such meeting, and any adjournment or postponement thereof, or to receive payment of such dividend, or to receive such allotment of rights, or to exercise such rights, as the case may be, notwithstanding any transfer of any shares on the books of the Corporation after such date of closing the stock transfer books or such record date fixed.

Section 4. Indemnification of Directors and Officers.

a. 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, suit, or proceeding 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 being defined as another corporation or other entity included in a controlled group of corporations or other entities 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 or other entity) 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 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.

b. 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 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, 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. 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. 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, the person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

c. Except as may otherwise be provided in the Articles of Incorporation or these Bylaws, any person who has been successful on the merits or otherwise in defense of any action, suit, or proceeding referred to in subsections (a) or (b) above, or in defense of any claim, issue, or matter therein, shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith.

d. Except as provided in subsection (e), indemnification of anyone under subsections (a) or (b), 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. Such a determination may be made by the Board 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 (by independent legal counsel in a written opinion) or by the shareholders.

e. Notwithstanding anything herein to the contrary, unless required by applicable law, no director, officer, or employee shall be indemnified against any expenses, penalties, or other payments incurred:

i. in an administrative action, suit, or proceeding 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), except under circumstances specifically permitted by such Act and regulations, or otherwise would constitute an indemnification payment that is prohibited by applicable law, or

ii. unless he or she notifies the Corporation in writing of the threatened, pending, or completed action, suit, or proceeding 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, or proceeding, or

iii. in connection with any settlement of a claim asserted or action, suit, or proceeding brought or threatened against him or her unless the Board (A) approved the amount of such settlement as (I) reasonable and (II) not affecting the Corporation’s safety and soundness or (B) 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

iv. in connection with 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 Exchange Act or similar provisions of any applicable law, or

v. 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.

f. The right to indemnification of officers and directors shall include the right, to the extent permissible under applicable law, to be paid by the Corporation reasonable expenses, including attorneys’ fees (but not including any retainers or prepayments of fees, unless such retainers or prepayments 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:

i. 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 that (A) such person is not entitled to be indemnified under this Section or otherwise or (B) 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

ii. until such time as the Board has made a final determination regarding indemnification under subsection (d). If the Board’s final determination is that indemnification is not proper, further advancement of expenses, including attorneys’ fees, will immediately cease. If the Board’s final determination is that indemnification is proper, indemnification of expenses, including attorneys’ fees, will continue.

g. If the claim of an officer or director for indemnification under these Bylaws is not paid in full by the Corporation within thirty (30) days after a written claim therefor 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. Neither the failure of the Corporation (including the Board, independent legal counsel, or 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 the Board, independent legal counsel, or 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.

h. The Corporation may purchase and maintain insurance or another arrangement 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 these Bylaws or applicable law; provided, however, that such insurance or other arrangement shall not provide coverage inconsistent with that permitted by applicable law.

i. 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 the Articles of Incorporation, these Bylaws, or any 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.

j. The right of any officer or director to be indemnified, reimbursed, or advanced amounts pursuant hereto:

i. 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,

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

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

Section 5. Amendments to Bylaws. The Board shall have the power to make, alter, amend, or repeal these Bylaws from time to time.
