Employee 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 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 who need to know such information, who shall be informed by Employee of the confidential nature of the Confidential Information and directed by Employee to treat the Confidential Information confidentially. Upon the Company's request, Employee shall return all information furnished to him related to the business of the Company without retaining any copies in electronic or other form.

     10.Use of Proprietary Information. Employee 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 Employee, except as otherwise agreed between the Company and Employee in writing. Employee expressly agrees that any products, inventions, discoveries or improvements made by Employee, his agents or affiliates, during the term of this Agreement, based on or arising out of the Confidential Information shall be the property of and inure to the exclusive benefit of the Company.

Upon any termination of Employee’s employment or engagement with the Company, Employee shall immediately return all Confidential Information (and all tangible embodiments thereof) possessed by Employee to the Company.

11.Non-Competition Agreement. 

     11.1Non-Competition. Employee agrees that, during the Employment Term and for a period of twelve (12) months following any termination of such employment, Employee 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, Kansas City 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 Employee 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. 

9

     11.2Non-Solicitation.

     (a)During the Employment Term and for a period of twelve (12) months following any termination of such employment, Employee shall not, except on behalf of or with the prior written consent of the Company, directly or indirectly:

(1)

entice or induce, or attempt to entice or induce, any employee of the Company to leave such employ, or employ any such person in any business similar to or in competition with that of the Company. Employee hereby acknowledges and agrees that the provisions set forth in this subsection 11.2 constitute a reasonable restriction on his ability to compete with the Company, or

(2)

(i) solicit, take away, attempt to take away, divert, or attempt to divert any Protected Customer (as defined below) from the Company or its Affiliates, (ii) induce, attempt to induce or aid any pin inducing any Protected Customer to cease doing business with the Company or any of its Affiliates or in any way interfere with the relationship between any Protected Customer and the Company or any or its Affiliates, or (iii) be employed by or act as a consultant for any Person which directly, or through any of its Affiliates, solicits, takes away, attempts to take away, diverts, or attempts to divert any Protected Customer from the Company or any of its Affiliates.

     (b)Before Employee becomes employed by or becomes a consultant for a Person during a Non-Solicitation Period, Employee shall inform such Person of the provisions of this Section 11.2 and, if within the first year following Employee'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, 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 Employee 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 Employee's employment with the Company. 

     (c)For purposes of this Agreement, "Protected Customer" means (i) any Person or its/his/her Affiliate for whom the Company or any of its Affiliates has provided wealth management, investment, banking, trust, insurance or other financial services during the Employment Term or (ii) any Person or its/his/her Affiliate whom the Company or any of its Affiliates had made a proposal to provide wealth management, investment, banking, trust, insurance or other financial services at anytime within six (6) months preceding the termination of Employee's employment with the Company.

     11.3Saving Provision. The parties hereto agree that, in the event a court of competent jurisdiction shall determine that the geographical or durational 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.

     11.4Equitable Relief. Employee acknowledges that the extent of damages to the Company from a breach of Sections 9, 10 and 11 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, Employee 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 9, 10 and 11 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

     12.Assignment. This Agreement shall not be assignable by Employee and shall not be assignable by the Company except by operation of law or to a successor entity acquiring all or substantially all the Company’s business or assets. No such assignment shall affect any determination of whether such assignment involves a Change of Control for purposes of this Agreement. In the event of any assignment permitted hereby, the duties and responsibilities of Employee performed for the assignee shall not, without the written consent of Employee, be materially increased, altered or diminished in a manner inconsistent with Employee’s duties and responsibilities hereunder for the Company.

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.

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.

     15.Modification.

     16.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.
