(b) Agreement. Each Option shall be evidenced by a written agreement containing such provisions as may be approved by the Committee. Each such Agreement shall constitute a binding contract between the Company and the Participant, and every Participant, upon acceptance of such Agreement, shall be bound by the terms and restrictions of the Plan and of such Agreement.

The Chairman of the Committee and such other Directors and officers as shall be designated by the Committee are hereby authorized to execute Agreements on behalf of the Company and to cause them to be delivered to the recipients of Options. (c) Effect of the Committee's Decisions. All decisions, determinations and interpretations of the Committee shall be final and conclusive on all persons affected thereby. (d) Indemnification. In addition to such other rights of indemnification as they may have, the members of the Committee shall be indemnified by the company in connection with any claim, action, suit or proceeding relating to any action taken or failure to act under or in connection with the Plan or any Option, granted hereunder to the full extent provided for under the Company's governing instruments with respect to the indemnification of Directors. 6. GRANT OF OPTIONS. The Committee shall have the discretion to grant Options to Employees and Directors (including members of the Committee). In selecting those Employees and Directors to whom Options will be granted and the number of shares covered by such Options, the Committee shall consider the position, duties and responsibilities of the eligible Employees and Directors, the value of their services to the Company and its Affiliates, and any other factors the Committee may deem relevant. Notwithstanding the foregoing, in the event that the Board determines that the Plan's effectiveness should be contingent upon the receipt of stockholder approval in order to satisfy exchange listing requirements, all Options granted pursuant to the Plan shall be contingent upon such approval. 7. EXERCISE PRICE FOR OPTIONS. (a) Limits on Committee Discretion. The Exercise Price as to any particular Option shall not be less than 100% of the Market Value of the Optioned Shares on the date of grant. (b) Standards for Determining Exercise Price. If the Common Stock is listed on a national securities exchange (including the NASDAQ National Market) on the date in question, then the Market Value per Share 3 shall be the average of the highest and lowest selling price on such exchange on such date, or if there were no sales on such date, then the Exercise Price shall be the mean between the bid and asked price on such date. If the Common Stock is traded otherwise than on a national securities exchange on the date in question, then the asked price on such date, then on the next prior business day on which there was a bid and asked price. If no such bid and asked price is available, then the Market Value per Share shall be its fair market value as determined by the Committee, in its sole and absolute discretion. 8. EXERCISE OF OPTIONS. (a) Generally. Each Option shall become fully (100%) exercisable immediately upon the date of its grant. An Option may not be exercised for a fractional Share. (b) Procedure for Exercise. A Participant may exercise Options, subject to provisions relative to its termination and limitations on its exercise, by (1) written notice of intent to exercise the Option with respect to a specified number of Shares, and (2) payment to the Company (contemporaneously with delivery of such notice) in cash, in Common Stock, or a combination of cash and Common Stock, of the amount of the Exercise Price for the number of Shares with respect to which the Option is then being exercised. Each such notice (and payment where required) shall be delivered, or mailed by prepaid registered or certified mail, addressed to the Treasurer of the Company at its executive offices. Common Stock utilized in full or partial payment of the Exercise price for Options shall be valued at its Market Value at the date of exercise, and may consist of Shares subject to the Option being exercised. (c) Period of Exercisability for Employees. Except to the extent otherwise provided in the terms of an Agreement, an Option may be exercised by a Participant only while he is an Employee and has maintained Continuous Service from the date of the grant of the Option, or within one year after termination of such Continuous Service (but not later than the date on which the Option would otherwise expire), except if the Employee's Continuous Service terminates by reason of - (1) "Just Cause" which for purposes hereof shall have the meaning set forth in any unexpired employment or severance agreement between the Participant and the Bank and/or the Company (and, in the absence of any such agreement, shall mean termination because of the Employee's personal dishonesty, incompetence, willful misconduct, breach of fiduciary duty involving personal profit, intentional failure to perform stated duties, willful violation of any law, rule or regulation (other than traffic violations or similar offenses) or final cease-and-desist order), then the Participant's rights to exercise such Option shall expire on the date of such termination; (2) death, then to the extent that the Participant would have been entitled to exercise the Option immediately prior to his death, such Option of the deceased Participant may be exercised within two years from the date of his death (but not later than the date on which the Option would otherwise expire) by the personal representative of his estate or person or persons to whom his rights under such Option shall have passed by will or by laws of descent and distribution. (d) Period of Exercisability for Non-Employee Directors. Except as otherwise provided in an Agreement, an Option may be exercised by a non-employee Director only during which he has maintained Continuous Service from the date of grant of the Option, provided that such Option shall (i) expire immediately if the non-employee Director's Continuous Service terminates due to Just Cause, and (ii) continue to be exercisable for three years following his termination of Continuous Service for any other reason. In the event of the non-employee Director's death, then to the extent that the non-employee Director would have been entitled to exercise the Option immediately prior to his death, such Option of the deceased non- employee Director may be exercised by the personal representatives of his estate or person or persons to whom his rights under such Option shall have passed by will or by laws of descent 3 and distribution. Notwithstanding the foregoing, an Option may not be exercised later than the date on which the Option would otherwise expire. (e) Effect of the Committee's Decision. The Committee's determination whether a Participant's Continuous Service has ceased, and the effective date thereof, shall be final and conclusive on all persons affected thereby. (f) Mandatory Six-Month Holding Period. Notwithstanding any other provision of this Plan to the contrary, common stock of the Company that is purchased upon exercise of an Option may not be sold within the six-month period following the grant of that Option, provided that such six-month holding period shall not apply in the event of a Transaction described in Paragraph 9(b) hereof. 9. EFFECT OF CHANGES IN COMMON STOCK SUBJECT TO THE PLAN. (a) Recapitalizations; Stock Splits, Etc. The number and kind of shares reserved for issuance under the Plan, and the number and kind of shares subject to outstanding Options, and the Exercise Price thereof, shall be proportionately adjusted for any increase, decrease, change or exchange or Shares for a different number or kind of shares or other securities of the Company which results from a merger, consolidation, recapitalization, reorganization, reclassification, stock dividend, split-up, combination of shares, or similar event in which the number or kind of shares is changed without the receipt or payment of consideration by the Company. (b) Transactions in which the Company is Not the Surviving Entity. In the event of (i) the liquidation or dissolution of the Company, (ii) a merger of consolidation in which the Company is not the surviving entity, or (iii) the sale or disposition of all or substantially all of the Company' s assets (any of the foregoing to be referred to herein as a "Transaction"), all outstanding Options, together with the Exercise Price thereof, shall be equitably adjusted for any change or exchange of Shares for a different number or kind of shares or other securities which results from the Transaction. (c) Conditions and Restrictions on New, Additional, or Different Shares or Securities. If, by reason of any adjustment made pursuant to this Paragraph, a Participant becomes entitled to new, additional, or different shares of stock or securities, such new, additional, or different shares of stock or securities shall thereupon be subject to all of the conditions and restrictions which were applicable to the Shares pursuant to the Option before the adjustment was made. (d) Other Issuances. Except as expressly provided in this Paragraph, the issuance by the Company or an Affiliate of shares of stock of any class, or of securities convertible into Shares or stock of another class, for cash or property or for labor or services either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, shall not affect, and no adjustment shall be made with respect to, the number, class, or Exercise Price of Shares then subject to Options or reserved for issuance under the Plan. 10. NON-TRANSFERABILITY OF OPTIONS. Options may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent and distribution. Notwithstanding the foregoing, or any other provision of this Plan, a Participant who holds Options may transfer such Options to his or her spouse, lineal ascendants, lineal descendants, or to a duly established trust for the benefit of one or more of these individuals. Options so transferred may thereafter be transferred only to the Participant who originally received the grant or to an individual or trust to 5 whom the Participant could have initially transferred the Options pursuant to this Paragraph 10. Options which are transferred pursuant to this Paragraph 10 shall be exercisable by the transferee according to the same terms and conditions as applied to the Participant. 11. TIME OF GRANTING OPTIONS. The date of grant of an Option shall, for all purposes, be the later of the date on which the Committee makes the determination of granting such Options, and the Effective Date. Notice of the determination shall be given to each Participant to whom an Option is so granted within a reasonable time after the date of such grant. 12. EFFECTIVE DATE. The Plan shall become effective upon the date of its approval by the Board. 13. MODIFICATION OF OPTIONS. At any time, and from time to time, the Board may authorize the Committee to direct execution of an instrument providing for the modification of any outstanding Option, provided no such modification shall confer on the holder of said Option any right or benefit which could not be conferred on him by the grant of a new Option at such time, or impair the Option without the consent of the holder of the Option. 14. AMENDMENT AND TERMINATION OF THE PLAN. The Board may from time to time amend the terms of the Plan and, with respect to any Shares at the time not subject to Options, suspend or terminate the Plan. No amendment, suspension or termination of the Plan shall, without the consent of any affected holders of an Option, alter or impair any rights or obligations under any Option theretofore granted. 15. CONDITIONS UPON ISSUANCE OF SHARES. (a) Compliance with Securities Laws. Shares of Common Stock shall not be issued with respect to any Option unless the issuance and delivery of such Shares shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, any applicable state securities law, and the requirements of any stock exchange upon which the Shares may then be listed. (b) Special Circumstances. The inability of the Company to obtain approval from any regulatory body or authority deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder shall relieve the Company of any liability in respect of the non-issuance or sale of such Shares. As a condition to the exercise of an Option, the Company may require the person exercising the Option to make such representations and warranties as may be necessary to assure the availability to an exemption from the registration requirements of federal or state securities laws. (c) Committee Discretion. The Committee shall have the discretionary authority to impose in Agreements such restrictions on Shares as it may deem appropriate or desirable, including but not limited to the authority to impose a right of first refusal or to establish repurchase rights or both of these restrictions. 6 16. RESERVATION OF SHARES. The Company, during the term of the Plan, will reserve and keep available a number of Shares sufficient to satisfy the requirements of the Plan. 17. WITHHOLDING TAX. The Company's obligation to deliver Shares upon exercise of Options shall be subject to the Participant's satisfaction of all applicable federal, state and local income and employment tax withholding obligations. The Committee, in its discretion, may permit the Participant to satisfy the obligation, in whole or in part, by irrevocably electing to have the Company withhold Shares, or to deliver to the Company Shares that he already owns, having a value equal to the amount required to be withheld. The value of the Shares to be withheld, or delivered to the Company, shall be based on the Market Value of the Shares on the date the amount of tax to be withheld is to be determined. As an alternative, the Company may retain, or sell without notice, a number of such Shares sufficient to cover the amount required to be withheld. 18. NO EMPLOYMENT OR OTHER RIGHTS. In no event shall an Employee's or Director's eligibility to participate or participation in the Plan create or be deemed to create any legal or equitable right of the Employee, Director, or any other party to continue service with the Company, the Bank, or any Affiliate of such corporations. No Employee or Director shall have a right to be granted an Option or, having received an Option, the right to again be granted an Option. However, an Employee or Director who has been granted an Option may, if otherwise eligible, be granted an additional Option or Options. 19. GOVERNING LAW. The Plan shall be governed by and construed in accordance with the laws of the State of Iowa, except to the extent that federal law shall be deemed to apply.
