Item 6. Indemnification of Directors and Officers.

Article IV of the By-Laws of the Company, consistent with the applicable provisions of the Missouri General and Business Corporation Law (“MGCBL”), provides for indemnification of directors and officers. Article IV provides as follows:

Each person who now is or hereafter becomes a director, officer or employee of the Company, or who now is or hereafter becomes a director or officer of another corporation, partnership, joint venture, trust or other enterprise at the request of the Company, shall be entitled to indemnification to the extent permitted by law and these By-Laws. Such right of indemnification shall include, but not be limited to, the following:

Section 1. (a)  The Company 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 Company, by reason of the fact that he is or was a director, officer or employee of the Company, or is or was serving at the request of the Company 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 in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. 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 reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

(b)  The Company 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 Company to procure a judgment in its favor by reason of the fact that he is or was a director, officer or employee of the Company, or is or was serving at the request of the Company as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against expenses, including attorneys’ fees, and amounts paid in settlement actually and reasonably incurred by him in connection with the defense or settlement of the action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company, 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 negligence or misconduct in the performance of his duty to the Company unless and only to the extent that the court in which the action or suit was brought determines upon application 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)  The Company shall further indemnify to the maximum extent permitted by law, 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 (including appeals), whether civil, criminal, investigative (including private Company investigations), or administrative, including an action by or in the right of the Company, by reason of the fact that the person is or was a director, officer or employee of the Company, or is or was serving at the request of the Company as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, from and against any and all expenses incurred by such person, including, but not limited to, attorneys’ fees, judgments, fines, and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding, provided that the Company shall not indemnify any person from or on account of such person’s conduct which was finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct.

(d)  To the extent that a director, officer or employee of the Company or a person who is or was serving at the request of the Company as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, has been successful on the merits or otherwise in defense of any action, suit, or proceeding referred to in this Section or in defense of any claim, issue or matter therein, he shall be indemnified against expenses, including attorneys’ fees, actually and reasonably incurred by him in connection with the action, suit, or proceeding.

Unless otherwise expressly provided by the Board of Directors, in no event shall any person who is or was an agent of the Company, or is or was serving at the request of the Company as an employee or agent of another corporation, partnership, joint venture, trust or enterprise, be entitled to any indemnification by the Company in any action, suit or proceeding, regardless of the fact that such person may have been successful on the merits or otherwise in defense of any action, suit or proceeding, or in defense of any claim, issue or matter therein. The preceding sentence is intended to eliminate any right any such person might otherwise have to be indemnified by the Company pursuant to Section 351.355.3. of the General and Business Corporation Law of Missouri.

(e)  Any indemnification under this Section, unless ordered by a court, shall be made by the Company only as authorized in the specific case upon a determination that indemnification of the director, officer or employee is proper in the circumstances because he has met the applicable standard of conduct set forth in this Section. The 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.

2

(f)  Where full and complete indemnification is prohibited by law or public policy, any person referred to in subsection (a) above who would otherwise be entitled to indemnification nevertheless shall be entitled to partial indemnification to the extent permitted by law and public policy. Furthermore, where full and complete indemnification is prohibited by law or public policy, any person referred to in this Section who would otherwise be entitled to indemnification nevertheless shall have a right of contribution to the extent permitted by law and public policy in cases where said party is held jointly or concurrently liable with the Company.

Section 2. The indemnification provided by Section 1 shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled under the Articles of Incorporation or By-Laws or any agreement, vote of shareholders or disinterested directors or otherwise both as to action in his official capacity and as to action in another capacity while holding such office, and the Company is hereby specifically authorized to provide such indemnification by any agreement, vote of shareholders or disinterested directors or otherwise. The indemnification shall continue as to a person who has ceased to be a director, officer or employee entitled to indemnification under this Article and shall inure to the benefit of the heirs, executors and administrators of such a person.

Section 3. The Company is authorized to purchase and maintain insurance on behalf of, or provide another method or methods of assuring payment to, any person who is or was a director, officer or employee of the Company, or is or was serving at the request of the Company as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any capacity, or arising out of his status as such, whether or not the Company would have the power to indemnify him against such liability under the provisions of this Article.

Section 4. Expenses incurred by a person who is or was serving as a director or officer of the Company or a person who is or was serving at the request of the Company as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, in defending a civil or criminal action, suit or proceeding referred to in Section 1 of this Article shall be paid by the Company in advance of the final disposition of the action, suit, or proceeding as shall be authorized by the Board of Directors in the specific case upon receipt of an undertaking by or on behalf of such person to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the Company as may be authorized in this Article. Expenses incurred by a person who is or was serving as an employee of the Company in defending a civil or criminal action, suit or proceeding referred to in Section 1 of this Article may be paid by the Company in advance of the final disposition of the action, suit, or proceeding as may be authorized by the Board of Directors in the specific case upon receipt of an undertaking by or on behalf of such employee to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the Company as authorized in this Article.

Section 5. If any provision or portion of this Article shall be held invalid, illegal or unenforceable for any reason whatsoever, the validity, legality and enforceability of all other provisions and portions not specifically held to be invalid, illegal or unenforceable, shall not be affected or impaired thereby and shall be construed according to the original intent, to the extent not precluded by applicable law.

Section 6. For purposes of this Article:

(a)  References to “the Company” 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 or employee of such a constituent corporation or is or was serving at the request of such 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 with respect to the resulting or surviving corporation as he would if he had served the resulting or surviving corporation in the same capacity.

3

(b)  The term “other enterprise” shall include employee benefit plans; the term “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and the term “serving at the request of the Company” shall be established as specified below in this Section 6(b) and shall include any service as a director, officer or employee of the Company which imposes duties on, or involves services by, such director, officer or employee with respect to an employee benefit plan, its participants, or beneficiaries; and the word “include” or “includes” shall be construed in its expansive sense and not as a limiter; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this Article. For purposes of this Article, “serving at the request of the Company” shall be established solely by (1) express approval by the Nominating and Corporate Governance Committee of such person’s service as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, (2) the annual review by the Nominating and Corporate Governance Committee of a list of non-affiliated corporations, partnerships, joint ventures, trusts or other enterprises that Company officers are serving as a director or officer of, so long as the Nominating and Corporate Governance Committee does not notify any such officer within 30 days after receiving such list that such person is not serving at the request of the Company or (3) a person serving as a director or officer of a Company Subsidiary, as hereinafter defined. The term “Company Subsidiary” shall mean any corporation, partnership, joint venture, trust or other enterprise, whether domestic or foreign, in which the Company has or obtains, directly or indirectly, a proprietary interest of more than fifty percent (50%) by reason of stock ownership or otherwise. Upon establishing that a person is “serving at the request of the Company” as described under (1) (2) and (3) above, such person’s service for purposes of this Article shall begin at the time of his initial service as a director or officer of such other corporation, partnership, joint venture, trust or other enterprise. The obligations of the Company under this Article to provide indemnification or advancement of expenses to a person serving at the request of the Company as a director or officer of another entity shall only apply to the extent that such person is not entitled to or does not receive indemnification or advancement of expenses from such other entity.

(c)  Notwithstanding anything to the contrary contained in these By-Laws or in Section 351.355.3 of the General and Business Corporation Law of Missouri, the maximum liability of the Company to any person “serving at the request of the Company,” at any time for all claims for indemnification and advancement of expenses for such person under these By-Laws or applicable law for such service shall for all purposes be limited to $25 million, except as otherwise expressly approved by the Board of Directors; provided, however, that the provisions of this Section 6(c) shall not be applicable in any respect to a person’s service only as a director or officer of a Company Subsidiary.

Section 7. This Article may be hereafter amended or repealed; provided, however, that no amendment or repeal shall reduce, terminate or otherwise adversely affect the right of a person who is or was a director, officer or employee to obtain indemnification or advancement of expenses with respect to an action, suit, or proceeding that pertains to or arises out of actions or omissions that occur prior to the effective date of such amendment or repeal.

Consistent with the applicable provisions of the MGBCL and the By-Laws, the Company has purchased insurance on behalf of its officers and directors which insures them against certain liabilities and expenses, including those under the Securities Act of 1933.

Item 9. Undertakings.

(a)            The undersigned registrant hereby undertakes:

(1)            To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)            To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)            To reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement; and

(iii)            To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in this registration statement.

(2)            That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)            To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

5

(4)            That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)            Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424,

(ii)            Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant,

(iii)            The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant, and

(iv)            Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(5)            That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(b)            Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
