Executive shall not, during the term of this Agreement, be engaged in any other outside business activity without the prior written consent of the CEO with the exception of paid Board membership with non-competing companies, as approved by the CEO; provided, however, that this restriction shall not be construed as preventing Executive from investing his personal assets in publicly traded stocks and bonds and similar passive assets.

(f) Acknowledgment, Enforceability. Executive acknowledges that, in exchange for the execution of the terms set forth in this Section 5, he has received substantial, valuable consideration, and that this Section 5 is the result of arms-length negotiations.

(a) Basis of Termination.

Page 5

(b) Termination by Executive with Notice. Executive may terminate his employment hereunder by giving the Bank sixty (60) days’ prior written notice, which termination shall be effective on the 60^th day following such notice (the “Notice Termination Date”). The Bank may, in lieu of continuing performance during the 60-day notice period, pay Executive his salary for the balance of the 60-day notice period without requiring further performance by Executive.

(c) Termination of Executive without Notice. Executive’s employment may be terminated by the Bank for any reason other than death, permanent incapacity (as defined in paragraph 6(a)(ii) above), or cause (as defined in paragraph 6(a)(iii) above) by giving fifteen (15) days’ prior written notice to Executive and such termination shall be effective as of the date of termination stated in such notice.

(d) Termination by Executive for Good Reason. Executive may terminate his employment for “good reason”. For purposes of this Agreement, good reason means:

Page 6

(e) Nonrenewal. Either the Bank or Executive may terminate this Agreement and the employment relationship that existed between them by giving written notice to the other not less than ninety (90) days before the end of the initial term hereof, or any subsequent renewal term.

(f) Termination of Executive “Non-Performance”. Executive’s employment may be terminated by the Bank for “non-performance,” effective upon delivery of written notice to Executive given at any time (without any necessity for prior notice) if any one of the following shall occur:

7. Payment upon Termination.

(a) Upon termination pursuant to Section 6(a) or (f)(ii), the Bank shall pay to Executive within ten (10) days after termination an amount equal to the sum of Executive’s Base Salary accrued to the date of termination, plus any unreimbursed expenses, vacation pay, and other benefits accrued to the date of termination.

(b) Upon termination pursuant to Section 6(b), the Bank shall pay to Executive, consistent with the Bank’s payroll practices (subject to the acceleration of contemplated by Section 6(b)), an amount equal to Executive’s Base Salary through the Notice Termination Date, plus any unreimbursed expenses, vacation pay, and other benefits accrued through the Notice Termination Date.

(c) Upon termination pursuant to Sections 6(c), (d), (e) or (f)(i), the Bank shall pay to Executive within ten (10) days after termination an amount equal to the sum of all compensation due to Executive under Section 4 accrued to the date of termination, including, without limitation, Executive’s Base Salary, bonus, vacation and management benefits, unreimbursed expenses, and other benefits. In addition, the Bank shall pay Executive an amount equal to twelve (12) months of Executives’ Base Salary, subject to Executive signing a general release of claims in a form reasonably acceptable to the Bank within twenty-one (21) days or forty-five (45) days, whichever period is required by applicable law. If Executive is in material breach of any of his obligations under Section 5 of this Agreement, the Bank may cease making these payments. If the Bank’s headquarters relocates from Wichita for any reason Executive is entitled to relocate or terminate according to Section 6(d).

(d) In addition to an amount equal to the sum of Executive’s Base Salary accrued to the date of a Change in Control Termination (defined below), plus any unreimbursed expenses, vacation pay, and other benefits accrued to the date of a Change

Page 7

in Control Termination, within thirty (30) days after a Change in Control Termination, the Bank shall pay Executive an amount equal to 2.99 times the sum of (i) the immediately prior year’s Base Salary and (ii) all additional cash compensation paid by the Bank and received by Executive during such year (but for the avoidance of doubt, it shall not include the value of any stock-based compensation) (“Change in Control Payment”); provided that in the event it is determined that any payment or distribution in the nature of compensation (within the meaning of Section 280G(b)(2) of the Internal Revenue Code), would constitute an “excess parachute payment” within the meaning of Section 280G of the Internal Revenue Code, then the Change in Control Payment under this Agreement shall be reduced by the maximum amount that may be paid without resulting in the imposition of excise tax on the Executive under Section 4999 of the Internal Revenue Code. Any required reduction in the Change in Control Payment pursuant to the foregoing shall be accomplished by first reducing the amount of cash payments due under Section 4 and then by any other cash payments due to Executive. All determinations to be made under this Section 7(d) shall be made by an independent public accounting firm selected by the Bank immediately prior to the Change in Control Termination, which shall provide its determinations and any supporting calculations both to the Bank and Executive within ten (10) days after the Change in Control Termination. Any such determination by such accounting firm shall be binding upon the Bank and Executive. The fees and expenses of such accounting firm in performing the determinations referred to in this Section shall be paid by the Bank. For the avoidance of doubt, if Executive is eligible for the payment described in this Section, he shall not be eligible for any other severance benefit, inclusive of the benefits described in Section 7(b) hereof.

(e) A “Change in Control Termination” shall mean (i) termination of Executive’s employment within twelve (12) months after a Change in Control (as defined below) for any reason other than death, “permanent incapacity”, “Cause” (as defined in Section 6(a)(iii) of this agreement), or (ii) Executive’s resignation from the Bank for any reason within twelve (12) months after the Change in Control.

(f) “Change in Control” shall mean the first to occur of any of the following events from and after the date of this Agreement:

Page 8

Notwithstanding the foregoing, no “Change in Control” shall be deemed to have occurred if there is consummated any transaction or series of integrated transactions immediately following which the holders of the common stock of Bancshares or Equity Bank immediately prior to such transaction or series of transactions continue to have substantially the same proportionate ownership in an entity which owns all or substantially all of the assets of Bancshares or Equity Bank immediately following such transaction or series of transactions.

For purpose of this Section, “beneficial ownership” shall be determined in accordance with Rule 13d-3 under the Exchange Act.

8. Notices. Any notices, requests, demands and other communications provided for by this Agreement shall be sufficient if in writing and delivered in person or sent by registered or certified mail, postage paid, to Executive at the last address Executive has filed in writing with

Page 9

the Bank, or, in the case of the Bank, to the attention of the CEO. All such communications shall be deemed given upon receipt. Any party may by notice in writing to the other parties change the address to which notices to it or him are to be addressed hereunder.

9. Internal Revenue Code Section 409A.

(a) It is intended that this Agreement will comply with Section 409A of the Code and any regulations and guidelines issued thereunder (collectively, “Section 409A”) to the extent this Agreement is subject thereto. This Agreement shall be interpreted on a basis consistent with such intent.

(b) If any payments or benefits provided to the Executive by the Bank, either per this Agreement or otherwise, are non-qualified deferred compensation subject to, and not exempt from, Section 409A (“Subject Payments”), the following provisions shall apply to such payments and/or benefits:

(c) For payments and benefits triggered by termination of employment, reference to the Executive’s “termination of employment” (and corollary terms) with the Bank shall be construed to refer to the Executive’s “separation from service” from the Bank (with such phrase determined under Treas. Reg. Section 1.409A-1(h), as uniformly applied by the Bank) in tandem with the termination of his employment with the Bank.

(d) If the Executive is deemed on the date of his “separation from service” to be a “specified employee” (within the meaning of Treas. Reg. Section 1.409A-l(i)), then with regard to any payment that is required to be delayed pursuant to Internal Revenue Code Section 409A(a)(2)(B) (the “Delayed Payments”), such payment shall not be made prior to the earlier of (i) the expiration of the six (6) month period measured from the date of his “separation from service” and (ii) the date of his death. Any payments other than the Delayed Payments shall be paid in accordance with the normal payment dates specified herein. In no case will the delay of any of the Delayed Payments by the Bank constitute a breach of the Bank’s obligations to the Executive.

(e) The Executive’s right to receive installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Bank.

(f) Notwithstanding any other provision of this Agreement to the contrary, in no event shall any Subject Payment be subject to offset by any other amount unless otherwise permitted by Section 409A.

(g) Notwithstanding anything herein to the contrary, in regard to Subject Payments, the definition of Change in Control set forth herein shall not be broader than the definition of “change in control event” as set forth under Section 409A, and if a transaction or event does not otherwise fall within such definition of “change of control event,” it shall not be deemed a Change in Control.

Page 10

(h) To the extent that any reimbursement or in-kind benefits are Subject Payments: (x) the amount eligible for reimbursement or in-kind benefit in one calendar year may not affect the amount eligible for reimbursement or in-kind benefit in any other calendar year (except that a plan providing medical or health benefits may impose a generally applicable limit on the amount that may be reimbursed or paid), (y) the right to reimbursement or an in-kind benefit is not subject to liquidation or exchange for another benefit, and (z) subject to any shorter time periods provided herein, any such reimbursement of an expense or in-kind benefit must be made on or before the last day of the calendar year following the calendar year in which the expense was incurred.

(i) If an amendment of this Agreement is necessary in order for it to comply with Section 409A, the Executive and the Bank agree to negotiate in good faith to amend this Agreement in a manner that preserves the original intent of the parties to the extent reasonably possible. No action or failure by the Bank in good faith to act, pursuant to this Section 20, shall subject the Bank to any claim, liability, or expense, and the Bank shall not have any obligation to indemnify or otherwise protect the Executive from the obligation to pay any taxes pursuant to Section 409A. The Bank does not make any representations as to the personal income tax treatment of any severance payments or other benefits provided to the Executive.

10. Miscellaneous.

(a) Entire Agreement. This Agreement constitutes the entire agreement between the parties and may not be changed except by a writing duly executed and delivered by the parties hereto.

(b) Governing Law. This Agreement is governed by and shall be construed in accordance with the laws of the State of Kansas, without giving effect to its conflicts of laws principles.

(c) Survival. Except as otherwise provided in this Agreement, upon the termination of this Agreement, the obligations of the Bank and Executive contained in Sections 5 and 6 shall survive and remain in effect.

(d) Enforcement. In view of the substantial harm which will result from the breach by Executive of any of the covenants contained in Section 5 the parties agree that such covenants shall be enforced to the fullest extent permitted by law. Accordingly, if, in any judicial proceeding, a court shall determine that such covenants are unenforceable because they cover too extensive a geographic area or survive for too long a period of time, or for any other reason, then the parties intend that such covenants shall be deemed to cover such maximum geographic area and maximum period of time and shall otherwise be deemed to be limited in such manner as will permit enforceability by such court. If any term or provision of this Agreement or the application thereof to any circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Agreement or the application to other persons and circumstances shall not be affected thereby and each term and provision hereof shall be enforced to the fullest extent permitted by law.

Page 11

(e) Remedies. Executive agrees that his breach of any of the provisions of Section 5 above will cause irreparable damage to the Bank and that the recovery by the Bank of money damages will not alone constitute an adequate remedy for such breach. Accordingly, Executive agrees that such provisions may be specifically enforced against him, in addition to any other rights or remedies available to the Bank on account of any such breach, and Executive hereby waives the defense in any equitable proceeding that there is an adequate remedy at law for any such breach and agrees that injunctive or other equitable relief will not constitute any hardship upon Executive.

(f) Assignment. The rights and obligations of the parties to this Agreement shall not be assignable, except that the rights and obligations of the Bank hereunder shall be assignable to any successor of the Bank upon a merger, reorganization or recapitalization or any entity that acquires substantially all of the assets of the Bank.

(g) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument, regardless of whether or not the signatures of all of the parties hereto appear on any single counterpart hereof. For purposes of this Agreement, the Bank and Executive agree that a facsimile or electronically transmitted counterpart bearing the signature of any party to this Agreement shall, absent manifest evidence of fraud, be binding upon such party when actually delivered to the other parties hereto.

(h) Notices. Unless otherwise provided herein, any and all payments, notices, requests, instructions and other communications required or permitted to be given under this Agreement after the date hereof by any party hereto to any other party may be delivered personally or by nationally recognized overnight courier service or sent by mail or (except in the case of payments) by facsimile transmission, at the respective addresses or transmission numbers set forth below and shall be effective (i) in the case of personal delivery, electronic transmission, when received; (ii) in the case of mail, upon the earlier of actual receipt or five (5) business days after deposit in the United States Postal Service, first class certified or registered mail, postage prepaid, return receipt requested; and (iii) in the case of nationally-recognized overnight courier service, one (1) business day after delivery to such courier service together with all appropriate fees or charges and instructions for such overnight delivery. The parties may change their respective addresses and transmission numbers by written notice to all other parties, sent as provided in this Paragraph 9(h).

(i) Remedies Cumulative; No Waiver. No remedy conferred upon either party by this Agreement is intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and shall be in addition to any other remedy given hereunder or now or hereafter existing at law or in equity. No delay or omission by either party in exercising any right, remedy, or power hereunder or existing at law or in equity shall be construed as a waiver thereof, and any such right, remedy, or power may be exercised by such party from time to time and as often as may be deemed expedient or necessary by such party in such party’s sole discretion.

(j) Arbitration. Subject to Section 9(e) hereof, any dispute, controversy, or claim arising out of or relating to this Agreement or breach thereof, or arising out of or relating in any way to the employment of Executive or the termination thereof, shall be submitted to arbitration in accordance with the Employment Dispute Arbitration Rules of the American Arbitration Association. The arbitration proceedings shall be held in the either Butler County, Kansas, or Sedgwick County, Kansas.
