Section 7. Non-Competition Covenant.

(a) Restrictive Covenant. The Bank and Executive have jointly reviewed the customer lists and operations of the Bank and have agreed that the primary service area of the Bank’s lending, deposit taking, trust, investment and other services in which the Executive has and will actively participate extends within the area which encompasses Johnson County, Iowa, and all contiguous counties (the “Restricted Area”). Therefore, as an essential ingredient of and in consideration of this Agreement and the payment of the amounts described in Section 2, Executive agrees that, except with the express prior written consent of the Bank, for a period of two years after the termination of Executive’s employment with the Bank (The “Restrictive Period”), the Executive will not (i) directly or indirectly compete with the business of the Bank by serving as an employee, officer, director or agent of or consultant to any person or entity that owns or operates an office of a bank, savings and loan association, credit union, securities broker or similar financial institution (a “Financial Institution”) within the Restricted Area, (ii) directly

4

or indirectly solicit or induce, or attempt to solicit or induce, any employee of the Bank to terminate employment for the Bank and to become an employee, officer, director, agent or consultant for a Financial Institution that owns or operates an office in the Restricted Area; or (iii) directly or indirectly solicit or induce, or attempt to solicit or induce, any person or entity that was a customer of the Bank during the Term to become a customer for a Financial Institution that owns or operates an office in the Restricted Area (all of the foregoing being the “Restrictive Covenant”). If Executive violates the Restrictive Covenant and the Bank brings legal action for injunction or other relief, the Bank shall not, as a result of the time involved in obtaining such relief, be deprived of the benefit of the full period of the Restrictive Covenant. Accordingly, the Restrictive Covenant shall be deemed to have the duration specified in this Section 7(a) computed from the date the relief is granted but reduced by the time between the period when the Restrictive Period began to run and the date of the first violation of the Restrictive Covenant by Executive. The foregoing Restrictive Covenant shall not prohibit Executive from owning directly or indirectly capital stock or similar securities which are listed on a securities exchange or quoted on the National Association or Securities Dealers Automated Quotation System which do not represent more then two percent (2%) of the outstanding capital stock of any Financial Institution.

(b) Remedies for Breach of Confidentiality, Loyalty or Restrictive Covenant. Executive acknowledges that the restrictions contained in Section 3 and 7(a) of this Agreement are reasonable and necessary for the protection of the legitimate business interests of the Bank, that any violation of these restrictions would cause substantial injury to the Bank and such interests, that the Bank would not have entered into this Agreement with Executive without receiving the additional consideration offered by Executive in binding himself to these restrictions and that such restrictions were a material inducement to the Bank to enter into this Agreement. In the event of any violation or threatened violation of these restrictions, the Bank, in addition to and not in limitation of, any other rights, remedies or damages available to the Bank under this Agreement or otherwise at law or in equity, shall be entitled to preliminary and permanent injunctive relief to prevent or restrain any such violation by Executive and any and all persons directly or indirectly acting for or with him, as the case may be.

Section 8. Interest in Assets. Neither Executive nor his estate shall acquire hereunder any rights in funds or assets of the Bank otherwise than by and through the actual payment of amounts payable hereunder; no shall Executive or his estate have any power to transfer, assign, anticipate, hypothecate or otherwise encumber in advance any of said payments; nor shall any of such payments be subject to seizure for the payment of any debt, judgment, alimony, separate maintenance or be transferable by operation of law in the event of bankruptcy, insolvency or otherwise Executive.

Section 9. General Provision.

(a) Successors; Assignment. This Agreement shall be binding upon and inure to the benefit of Executive, the Bank and his and its respective personal representatives, successors and assigns, and any successor or assign of the Bank shall be deemed “the Bank” hereunder.

(b) Entire Agreement; Modification. This Agreement constitutes the entire agreement between the parties respecting the subject matter hereof and supersedes all prior

5

negotiations, undertakings, agreements and arrangements with respect thereto, whether written or oral. Except as otherwise explicitly provided herein, this Agreement may not be amended or modified except by written agreement signed by Executive and the Bank.

(c) Enforcement and Governing Law. This Agreement shall be construed and the legal relations of the parties hereto shall be determined in accordance with the laws of the state of Iowa without reference to the law regarding conflicts of law.

(d) Legal Fees. All reasonable legal fees paid or incurred by a party to this Agreement pursuant to any dispute or question of interpretation relating to this Agreement shall be paid or reimbursed by the party who is unsuccessful on the merits pursuant to a legal judgment.

(e) Waiver. No waiver by either party at any time of any breach by the other party of, or compliance with, any condition or provision of this Agreement to be performed by the other party, shall be deemed a waiver of any similar or dissimilar provisions or conditions at the same time or any prior or subsequent time.

(f) Severability of Provisions. If for any reason any paragraph, term or provision of this Agreement is held to be invalid or unenforceable, all other valid provisions hereof shall remain in full force and effect and all of the terms, provisions and paragraphs of this Agreement shall be deemed to be severable in nature. If for any reason any provision containing restrictions set forth herein is held to cover an area or to be for a length of time which is unreasonable, or in any other way is construed to be too broad or to any extent invalid, any such provision shall not be determined to be null, voice and of no effect, but to the extent the same is or would be valid or enforceable under applicable law, any court of competent jurisdiction shall construe and interpret or reform this Agreement to provide for a restriction having the maximum enforceable area, time period and other provisions (not greater than those contained herein) as shall be valid and enforceable under applicable law.

(g) Notices. Notices pursuant to this Agreement shall be in writing and shall be deemed given when received; and, if mailed, shall be mailed by United States registered or certified mail, return receipt request, postage prepaid; and if to the Bank, addressed to the principal headquarters of the Bank, attention: Chairman; or, if to Executive, to the address set forth below Executive’s signature on this Agreement, or to such other address as the party to be notified shall have given to the other.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement the day and year first above written.
