Such amounts will be paid to Executive in a single sum cash payment, subject to applicable taxes and withholding within ten (10) days of the satisfaction of all of the conditions in Section 5.3(b).

6.1Separation From Service. Any amount that (i) is payable upon termination of Executive’s employment with the Company under any provision of this Agreement, and (ii) is subject to the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), shall not be paid unless and until the Executive has Separated from Service. As used in this

Agreement, the terms “Separated from Service” and “Separation from Service” shall have the meaning specified in Treasury Regulation Section 1.409A-1(h).

6.2Specified Employee. If Executive is a “specified employee” (within the meaning of Section 409A) of Company at the time of his termination of employment and if payment of severance compensation to the Executive is on account of an “involuntary separation from service” (as defined in Treasury Regulation Section 1.409A-1(n)), Executive shall be paid such severance compensation during the six (6) month period immediately following the date of his Separation from Service as otherwise provided under Section 5 for such six (6) month period except that the total amount of such payments shall not exceed the lesser of the amount specified under (i) Treasury Regulation Section 1.409A-1(9)(iii)(A)(1) or (ii) Treasury Regulation Section 1.409A-1(9)(iii)(A)(2). To the extent such amounts otherwise payable during such six (6) month period exceed the amounts payable under the immediately preceding sentence, such excess amounts shall not be paid during such six (6) month period, but instead shall be paid in a single sum on the first regular payroll date of Company immediately following the six (6) month anniversary of the date of Executive’s Separation from Service. If Executive is a specified employee and Executive’s Separation from Service is not an involuntary separation from service as defined in Treasury Regulation Section 1.409A-1(n), then any severance compensation and any other amount due to Executive under this Agreement that is subject to Section 409A and that would otherwise have been paid during the six (6) month period immediately following the date of Executive’s Separation from Service shall be paid in a single sum on the first payroll date of Company immediately following the six (6) month anniversary of Executive’s Separation from Service. Amounts, the payment of which are deferred under this Section, shall be increased by interest at the prime rate as of the date of Executive’s Separation from Service as published in the Wall Street Journal from the date such amounts would have been paid but for this provision and such accumulated interest shall also be paid to the Executive on the first payroll date of Company immediately following the six (6) month anniversary of Executive’s Separation from Service.

Notwithstanding the provisions of this Section 6, the Company has no responsibility or obligation to Executive with respect to any tax that may be incurred by Executive pursuant to Section 409A.

7.Death of Executive. In the event Executive dies before amounts are paid to him under this Agreement, such amounts shall be paid to his designed beneficiary of beneficiaries, or if there are no designated beneficiary or beneficiaries, to his estate.

8.Confidentiality; Non-Disparagement.

8.1Executive agrees to hold in strict confidence and not disclose all non-public information concerning any matters affecting or relating to the business of the Company and its Affiliates, including without limiting the generality of the foregoing non-public information concerning their manner of operation, business or other plans, data bases, marketing programs, protocols, processes, computer programs, client lists, marketing information and analyses, operating policies or manuals or other data (the “Confidential Information”). Executive agrees that he will not, directly or indirectly, use any Confidential Information for the benefit of any person, business, legal entity other than the Company and its Affiliates or disclose or communicate any of the Confidential Information in any manner whatsoever other than to the directors, officers, employees, agents and representatives of the Company and its Affiliates who need to know such information, who shall be informed by Executive of the confidential nature of the Confidential Information and directed by Executive to treat the Confidential Information confidentially. Upon the Company’s request, Executive shall return all information furnished to him related to the business of the Company and its Affiliates without retaining any copies in electronic or other form. The above limitations on use

and disclosure shall not apply to information which Executive can demonstrate: (a) was known to Executive before receipt thereof from the Company or its Affiliates; (b) is learned by Executive from a third party entitled to disclose it; or (c) becomes known publicly other than through Executive; (d) is disclosed by Executive upon authority of the Company Board or any committee of the Company Board; (e) is disclosed pursuant to any legal requirement or (f) is disclosed pursuant to any agreement to which the Company or any of its Subsidiaries or Affiliates is a party. The parties hereto stipulate that all such information included in the definition of “Confidential Information” herein is material and confidential and gravely affects the effective and successful conduct of the business of the Company and the Company’s goodwill, and that any breach of the terms of this Section 8 shall be a material breach of this Agreement.

8.2Executive further agrees that, during the Employment Term and thereafter (regardless of the reason for such termination), Executive will not, directly or indirectly, in any individual or representative capacity whatsoever, make any statement, oral or written, or perform any other act or omission which is or is likely to be materially detrimental to the goodwill or the Company or any of its Subsidiaries or Affiliates.

9.Use of Proprietary Information. Executive recognizes that the Company possesses a proprietary interest in all of the Confidential Information and has the exclusive right and privilege to use, protect by copyright, patent or trademark, manufacture or otherwise exploit the processes, ideas and concepts described therein to the exclusion of Executive, except as otherwise agreed between the Company and Executive in writing. Executive expressly agrees that any products, inventions, discoveries or improvements made by Executive, his agents or affiliates, during the Employment Term, based on or arising out of the Confidential Information shall be the property of and inure to the exclusive benefit of the Company. Executive further agrees that any and all products, inventions, discoveries or improvements developed by Executive (whether or not able to be protected by copyright, patent or trademark) in the scope of his employment, or involving the use of the Company’s time, materials or other resources, shall be promptly disclosed to the Company and shall become the exclusive property of the Company. Upon any termination of Executive’s employment or engagement with the Company, Executive shall immediately return all Confidential Information (and all tangible embodiments thereof) possessed by Executive to the Company.

10.1Non-Competition. Because of Executive’s unique and specialized position within Company and Executive’s access to and familiarity with Company’s Confidential business methodologies, Executive agrees that, during the Employment Term and for a period of one (1) year following a termination of Executive’s employment for any reason (the “Non-Compete Period”), Executive shall not, without the prior written consent of the Company, directly or indirectly, own, manage, operate, control, be connected with as an officer, employee, partner, consultant or otherwise, or otherwise engage or participate in (except as an employee of the Company, or its Affiliates) any Person engaged in the operation, ownership or management of a bank, trust company, wealth management or financial services business within the Metropolitan Statistical Areas of St. Louis, Missouri, Kansas City, Missouri, Phoenix, Arizona or any other city in which the Company or any of its Affiliates has an office at the time of such termination. Notwithstanding the foregoing, the ownership by Executive of less than 1% of any class of the outstanding capital stock of any corporation conducting such a competitive business which is regularly traded on a national securities exchange or in the over-the-counter market shall not be a violation of the foregoing covenant.

(a)    During the Employment Term and continuing during the Non-Compete Period, Executive shall not, except on behalf of or with the prior written consent of the Company, directly or indirectly, whether alone or in association, or combination with any other Person, or as an officer, director, shareholder, member, manager, employee, agent, independent contractor, consultant, advisor, joint venturer, partner or otherwise and whether or not for pecuniary benefit:

(i)    solicit, take away, attempt to take away, divert, attempt to divert, engage in business with, contract with or in any way interfere with the relationship between any Customer or Prospective Customer (in each case, as defined below) and the Company or its Affiliates.

(ii)    (A) hire or employ any other employee of the Company or its Affiliates, (B) entice, solicit, recruit or induce any other employee of the Company or its Affiliates to leave such employ or (C) otherwise interfere with the employment of any other employee of the Company or its Affiliates.

(b)    Before Executive becomes employed by or becomes a consultant for a Person during the Non-Compete Period, Executive shall inform such Person of the provisions of this Section 10.2 and, if within the first year following Executive’s termination of employment with the Company, shall cause such Person to sign a document acknowledging this provision and agreeing with the Company, on behalf of itself and its Affiliates, to abide to the terms of such obligation to not solicit, take away, conduct any wealth management or banking business with, attempt to take away, divert or attempt to divert, any Protected Customer, and deliver such document to the Company. Provided, however, that nothing contained herein shall prevent such Person employing Executive from continuing to provide services to any individual or other entity that was a customer of the Person prior to the date of the termination of Executive’s employment with the Company. Company may advise any third party with whom Executive may consider, establish or contract a relationship, including but not limited to an employment relationship of this Agreement and its terms, and the Company shall have no liability for so acting.

(c)    For purposes of this Agreement, “Protected Customer” means any Person and its/his/her Affiliate (i) for whom the Company or any of its Affiliates has provided financial services, including without limitation wealth management, sales of tax credits, investment, banking, trust, insurance or other financial services within the twenty-four (24) month period prior to the termination of Executive’s employment with the Company or (ii) to whom the Executive on behalf of the Company or any of its Affiliates had made a proposal to provide any financial services, including without limitation wealth management, sales of tax credits, mortgage lending investment, banking, trust, insurance or other financial services, at any time within twelve (12) months preceding the termination of Executive’s employment with the Company.

10.3Saving Provision. The parties hereto agree that, in the event a court of competent jurisdiction shall determine that the geographical, durational or other elements of this covenant are unenforceable, such determination shall not render the entire covenant unenforceable. Rather, the excessive aspects of the covenant shall be reduced to the threshold which is enforceable, and the remaining aspects shall not be affected thereby. The parties intend that the restrictions of this Section

10 be given the construction that renders their provisions valid and enforceable to the maximum extent possible under applicable law.

10.4Equitable Relief. Executive acknowledges that the extent of damages to the Company from a breach of Sections 8, 9 and 10 of this Agreement would not be readily quantifiable or ascertainable, that monetary damages would be inadequate to make the Company whole in case of such a breach, and that there is not and would not be an adequate remedy at law for such a breach. Therefore, Executive specifically agrees that the Company is entitled to injunctive or other equitable relief (without any requirement to post any bond or other security) from a breach of Sections 8, 9 and 10 of this Agreement, and hereby waives and covenants not to assert against a prayer for such relief that there exists an adequate remedy at law, in monetary damages or otherwise.

10.5    Tolling. Executive agrees that, in the event of a breach of any of the provisions of this Section 10, the time period specified in such provisions shall be extended by the number of days between the date of such breach and the date such breach is enjoined or other relief is granted to the Company by a court of competent jurisdiction. It is the intention of the parties that the Company shall enjoy the faithful performance by Executive of the covenants specified in this Section 10 for the full time periods specified herein.

10.6    Reasonableness of Restrictive Covenants. Executive recognizes that as an employee and/or officer of the Company, (i) Executive will have substantial customer contacts, perform special and unique duties and services for the Company and its Affiliates and acquire Confidential Information, (ii) the Confidential Information is the property of the Company and its Affiliates and the use, misappropriation, or disclosure of the Confidential Information would constitute a breach of trust and could cause irreparable injury to the Company and its Affiliates; and it is essential to the protection of the Company’s and its Affiliates’ good will and to the maintenance of the Company’s and its Affiliates’ competitive position that the Confidential Information be kept secret, and (iii) the Company and its Affiliates have a valid, protectable right and business interest in preserving the relationships described in this Agreement. The Company and Executive further agree that but for Executive’s agreement to the provisions of Sections 8, 9 and 10 of this Agreement, Executive would not be eligible for employment by the Company on an “at will” basis and for no definite term and the Company would not make available or continue to make available to Executive the Confidential Information. Executive further agrees that: (A) the covenants and agreements contained herein are reasonable and necessary in order to protect the legitimate business interests of the Company and its Affiliates; and (B) the enforcement of such covenants would not unreasonably impair Executive’s ability to earn a livelihood.

11.Assignment. This Agreement is personal to Executive and shall not be assignable by him.

12.Entire Agreement. This Agreement and any agreements entered into after the date hereof under any of the Company’s benefit plans or compensation programs as described in Section 4 contain the complete agreement concerning the employment arrangement between the parties, including without limitation severance or termination pay, and shall, as of the Effective Date, supersede all other agreements or arrangements between the parties with regard to the subject matter hereof.

13.Binding Agreement. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns. The obligations of the Company under this Agreement shall not be terminated by reason of any liquidation, dissolution, bankruptcy, cessation of business or similar event relating to the Company. This Agreement shall not be

terminated by reason of any merger, consolidation or reorganization of the Company, but shall be binding upon and inure to the benefit of the surviving or resulting entity.

14.Modification. No waiver or modification of this Agreement or of any covenant, condition, or limitation herein contained shall be valid unless authorized by the Company Board and reduced to in writing and duly executed by the party to be charged therewith and no evidence of any waiver or modification shall be offered or received in evidence of any proceeding, arbitration, or litigation between the parties hereto arising out of or affecting this Agreement, or the rights or obligations of the parties thereunder, unless such waiver or modification is in writing, duly executed as aforesaid.

15.Severability. All agreements and covenants contained herein are severable, and in the event any of them shall be held to be invalid or unenforceable by any court of competent jurisdiction, this Agreement shall be interpreted as if such invalid agreements or covenants were not contained herein.

16.Manner of Giving Notice.
