ARTICLE IV

DIRECTORS

SECTION 4.1. NUMBER AND CLASSIFICATION. The number of Directors to constitute the Board of Directors of the Corporation shall be fixed by or in the manner provided in the Bylaws of the Corporation. Any changes in the number of Directors shall be reported to the Missouri Secretary of State to the extent and within the time periods required by the GBCL. As of the effective date of these Articles of Incorporation, the Directors shall be divided into three classes, as nearly equal in number as is reasonably possible, with the term of office of the first class to expire at the 2016 annual meeting of shareholders, the term of office of the second class to expire at the 2017 annual meeting of shareholders and the term of office of the third class to expire at the 2018 annual meeting of shareholders, with each Director to hold office until his or her successor shall have been duly elected and qualified. At each annual meeting of shareholders (i) Directors elected to succeed those Directors whose terms then expire shall be elected for a term of office to expire at the third succeeding annual meeting of shareholders after their election, so that the term of office of only one class of Directors shall expire at each annual

3

meeting, with each Director to hold office until his or her successor shall have been duly elected and qualified or until his or her earlier death, resignation or removal, and (ii) if authorized by a resolution of the Board of Directors, Directors may be elected to fill any vacancy on the Board of Directors, regardless of how such vacancy shall have been created. Notwithstanding the foregoing, whenever the holders of any one or more classes or series of stock of the Corporation, other than shares of Common Stock, shall have the right, voting separately by class or series, to elect Directors, then the election, term of office, filling of vacancies and other features of such directorship shall be governed by the terms of the Articles of Incorporation of the Corporation or any certificate of designation thereunder applicable thereto. As used in these Articles of Incorporation, the term “entire Board of Directors” or the “entire Board” means the total number of Directors fixed by, or in accordance with, these Articles of Incorporation and the Bylaws of the Corporation.

SECTION 4.2. REMOVAL OF DIRECTORS. Subject to, and in addition to, the rights, if any, of the holders of any class of capital stock of the Corporation (other than the Common Stock) then outstanding or any limitation imposed by law, (i) any Director, or the entire Board of Directors, may be removed from office at any time prior to the expiration of his, her or their term of office only for cause and only by the affirmative vote of the holders of record of outstanding shares representing not less than two-thirds of all of the then outstanding shares of capital stock of the Corporation then entitled to vote generally in the election of Directors, voting together as a single class, at a special meeting of shareholders called expressly for that purpose (such vote being in addition to any required class or other vote), and (ii) any Director may be removed from office by the affirmative vote of a majority of the entire Board of Directors at any time prior to the expiration of his or her term of office, as provided by law, in the event that the Director fails to meet any qualifications stated in the Bylaws for election as a Director or in the event that the Director is in breach of any agreement between the Director and the Corporation relating to the Director’s service as a Director or employee of the Corporation.

SECTION 4.3. VACANCIES. Subject to the rights, if any, of the holders of any class of capital stock of the Corporation (other than the Common Stock) then outstanding, and except as expressly provided for in Section 4.1, any vacancies in the Board of Directors which occur for any reason, including vacancies which occur by reason of an increase in the number of Directors or the removal of a Director, shall be filled only by the Board of Directors, acting by the affirmative vote of a majority of the remaining Directors then in office (although less than a quorum). Any replacement Director so elected shall hold office for a term expiring at the annual meeting of shareholders at which the term of office of the class to which they have been appointed expires and until such Director’s successor is elected and qualified or until such Director’s earlier death, resignation or removal.

Without limiting the generality of the foregoing, the Corporation shall indemnify any such person (other than a party plaintiff suing on his or her behalf or in the right of the Corporation), who was or is a party or is threatened to be made a party, to any threatened, pending or completed action, suit or

5

proceeding, whether civil, criminal, administrative or investigative (including, but not limited to, an action by or in the right of the Corporation) as a result of such service or any other service on behalf of the Corporation while also serving as a Director, officer or employee of the Corporation against expenses (including, without limitation, costs of investigation and 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.

SECTION 8.2. MANDATORY INDEMNIFICATION.

(a) Directors, Officers and Employees. To the extent that a Director, officer or employee of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding, to which action, suit or proceeding such Director, officer or employee was or is a party by reason of such person’s service to the Corporation in such capacity, or as a result of any other service on behalf of the Corporation while also serving as a Director, officer or employee of the Corporation, or in defense of any claim, issue or matter therein, he or she shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection with the action, suit or proceeding, or proportionally to such claim, issue or matter therein.

(b) Agents. To the extent that an agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding, to which action, suit or proceeding such agent was or is a party by reason of service to the Corporation in such capacity, or as a result of any other service on behalf of the Corporation while also serving as an agent of the Corporation, or in defense of any claim, issue or matter therein, the Corporation is not required to, but may, in its discretion, indemnify such individual against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection with the action, suit or proceeding, or proportionally to such claim, issue or matter therein, at the discretion of the Corporation.

SECTION 8.3. ARTICLE VIII PROVISIONS NOT EXCLUSIVE RIGHT.

SECTION 8.4. INDEMNIFICATION AGREEMENTS AUTHORIZED. Without limiting the other provisions of this Article VIII, the Corporation is authorized from time to time, without further action by the shareholders of the Corporation, to enter into agreements with any Director, officer, employee or agent of the Corporation providing such rights of indemnification as the Corporation may deem appropriate, up to the maximum extent permitted by law. Any agreement entered into by the Corporation with a Director may be authorized by the other Directors, and such authorization shall not be invalid on the basis that different or similar agreements may have been or may thereafter be entered into with other Directors.

SECTION 8.5. STANDARD OF CONDUCT. Except as may otherwise be permitted by law, no person shall be indemnified pursuant to this Article VIII (including without limitation pursuant to any agreement entered into pursuant to Section 8.4 of these Articles of Incorporation) from or on account of such person’s conduct which is finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct. The Corporation may (but need not) adopt a more restrictive standard of conduct with respect to the indemnification of any agent of the Corporation.

SECTION 8.6. INSURANCE. The Corporation may purchase and maintain insurance on behalf of itself or any person who is or was a Director, officer, employee or agent of the Corporation, or who is or was otherwise serving on behalf or at the request of the Corporation in any capacity against any claim, liability or expense 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 VIII.

SECTION 8.7. CERTAIN DEFINITIONS. For the purposes of this Article VIII:

(a) Service in Representative Capacity. Any Director, officer or employee of the Corporation who shall serve as a director, officer or employee of any other corporation, partnership, joint venture, trust or other enterprise of which the Corporation, directly or indirectly, is or was the owner of 20% or more of either the outstanding equity interests or the outstanding voting stock (or comparable interests) shall be deemed to be so serving at the request of the Corporation, unless the Board of Directors of the Corporation shall determine otherwise. In all other instances where any person shall serve as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise of which the Corporation is or was a stockholder or creditor, or in which it is or was otherwise interested, if it is not otherwise established that such person is or was serving as a director, officer, employee or agent at the request of the Corporation, the Board of Directors of the Corporation may determine whether such service is or was at the request of the Corporation, and it shall not be necessary to show any actual or prior request for such service.

(b) Predecessor Corporations. References to a corporation include all constituent corporations absorbed in a consolidation or merger, as well as the resulting or surviving corporation, so that any person who is or was a director, officer, employee or agent of a constituent corporation or is or was serving at the request of a constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise shall stand in the same position under the provisions of this Article VIII with respect to the resulting or surviving corporation as he or she would if he or she had served the resulting or surviving corporation in the same capacity.

The term “other enterprise” shall include, without limitation, employee benefit plans and voting or taking action with respect to stock or other assets therein; the term “serving at the request of the Corporation” shall include, without limitation, any service as a director, officer, employee or agent of a corporation which imposes duties on, or involves services by, a director, officer, employee or agent with respect to any employee benefit plan, its participants or beneficiaries; a person who acted in good faith and in a manner he or she reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have satisfied any standard of care required by or

7

pursuant to this Article VIII in connection with such plan; and the term “fines” shall include, without limitation, any excise taxes assessed on a person with respect to an employee benefit plan and shall also include any damages (including treble damages) and any other civil penalties.

SECTION 8.8. LIABILITY OF THE DIRECTORS, OFFICERS AND EMPLOYEES.

(a) No Director of the Corporation shall be personally liable to the Corporation or its shareholders for monetary damages for breach of fiduciary duty as a Director; provided, however, that the foregoing clause shall not apply to any liability of a Director (i) for any breach of the Director’s duty of loyalty to the Corporation or its shareholders, (ii) for acts or omissions not in subjective good faith or which involve intentional misconduct or a knowing violation of law, (iii) under § 351.345 of the GBCL, or (iv) for any transaction from which the Director derived an improper personal benefit.

(b) It is the intention of the Corporation to limit the personal liability of the Directors, officers and employees of the Corporation, in their capacity as such, whether to the Corporation, its shareholders or otherwise, to the fullest extent permitted by law. Consequently, should the GBCL or any other applicable law be amended or adopted hereafter so as to permit the elimination or limitation of such liability, the liability of the Directors and/or officers and/or employees of the Corporation shall be so eliminated or limited without the need for amendment of these Articles or for further action on the part of the shareholders of the Corporation.

SECTION 8.9. SURVIVAL; AMENDMENT.

(a) Each person who was or is a Director, officer or employee of the Corporation is a third party beneficiary to this Article VIII, shall be entitled to rely upon all of his or her indemnification rights provided or contemplated by this Article VIII as a binding contract with the Corporation, and shall be entitled to enforce against, and rely on as a binding contract with, the Corporation all of his or her indemnification rights provided or contemplated by this Article VIII. Such indemnification rights shall continue as to a person who has ceased to be a Director, officer or employee, and shall inure to the benefit of the heirs, executors and administrators of such a person.

(b) This Article VIII may be hereafter amended, modified or repealed as provided in Article IX of these Articles of Incorporation; provided, however, that no such amendment, modification or repeal shall (i) reduce, terminate or otherwise adversely affect any right or protection, provided in this Article VIII of any person who was or is a Director, officer or employee of the Corporation to obtain indemnification or an advance of expenses with respect to a proceeding that pertains to or arises out of any act, omission or event occurring or condition or circumstance existing prior to the Deadline Indemnification Date, or (ii) have any effect on the liability or alleged liability of any person who was or is a Director, officer or employee of the Corporation for or with respect to any act, omission or event occurring or condition or circumstance existing prior to the Deadline Indemnification Date. For purposes of this Section 8.9, the term “Deadline Indemnification Date” shall mean the later of: (1) the effective date of any amendment or repeal of this Article VIII which reduces, terminates or otherwise adversely affects the rights hereunder of any person who was or is a Director, officer or

8

employee, (2) the expiration of such person’s then current term of office with, or service for, the Corporation (provided such person has a stated term of office or service and completes such term), or (3) the effective date such person resigns his office or terminates his service (provided such person has a stated term of office or service but resigns prior to the expiration of such term).
