This STOCK OPTION AGREEMENT (the “Agreement”) is made and entered into, as of the Date of Agreement set forth above, by and between County Bancorp, Inc., a Wisconsin corporation (“Company”) and the Participant named above:

PREMISES

WHEREAS, the Company has adopted the County Bancorp, Inc. Management Incentive Plan (the “Plan”) under which the Committee (as defined in the Plan) may, among other things, grant options to key officers and employees of the Company and its subsidiaries to purchase shares of the Company’s common stock, par value $.01 per share (“Stock”), subject to terms, conditions, and restrictions as in its discretion it shall deem appropriate; and

WHEREAS, the Participant is a key officer and employee of the Company or a Subsidiary and the Option is granted as an incentive to continue Participant’s services and to increase Participant’s proprietary interest in the Company; and

WHEREAS, pursuant to the Plan, the Committee has made a grant to the Participant to purchase shares of the authorized but unissued Stock of the Company conditioned upon the due execution of this Agreement.

AGREEMENT

NOW, THEREFORE, in consideration of the premises and of the covenants and agreements herein set forth, the parties hereby mutually covenant and agree as follows:

1. Option Grant. The Company, in consideration of the continued employment of the Participant for the periods herein defined, grants to the Participant an Option, pursuant to the Plan, to purchase the number of shares of Stock of the Company, par value of $0.01 per share, set forth in the table on page 1 as the Number of Shares Optioned, at the Exercise Price Per Share set forth in the table on page 1, and otherwise upon the terms and conditions set forth herein.

2. Duration and Exercise of Option. This Option expires on the Option Expiration Date set forth above or prior thereto in the event of death or termination of employment of the Participant, as provided herein. The exercise of this Option is contingent upon receipt by the Company of the full purchase price of such shares, During the period between the date of the grant of this Option and the end of the tenth year after the date of the granting of this Option, this Option may be exercised with respect to not more than the percentage of the total number of Option Shares as set forth in the following schedule:

3. Certain Restrictions. The Option granted hereby may be exercised only with respect to whole shares of stock. The minimum number of Optioned Shares which may be purchased at one time shall be lesser of 100 Optioned Shares or ten percent (10%) of the aggregate number of Option Shares granted hereunder. Nothing herein contained shall be construed to extend the ultimate term of this Option beyond the period of ten (10) years from the date of the grant of this Option.

4. Manner of Exercise. The Option may be exercised only by written notice, delivered or mailed by postpaid, registered or certified mail, addressed to the secretary of the Company specifying the number of Optioned Shares being purchased. Such notice shall be accompanied by (i) payment in cash or its equivalent of the entire Exercise Price of the Optioned Shares being purchased; (ii) only with the prior written consent of the Committee, by tendering previously acquired shares of Stock having a Fair Market Value (determined by the Committee in conformity with the requirements of the Plan) at the time of exercise equal to the entire purchase price of the Optioned Shares being purchased; or (iii) any combination of the foregoing. The Committee may then require that there be presented to and filed with it such evidence as it may deem sufficient to establish that the Participant is bona fide resident of the State of Wisconsin on the date of exercise, and that the shares to be purchased are being acquired for investment and not with a view to their distribution. The Committee, in its discretion, may provide through any subsidiary bank of the Company to make a loan to the Participant to finance the exercise of any Option as well as the estimated or actual amount of taxes that may be payable. The loan shall be evidenced by a promissory note for a term of one year and shall be secured or unsecured as may be determined.

2

Shares of Stock tendered shall be duly endorsed or accompanied by stock powers duly endorsed in blank. Upon receipt of the payment of the entire purchase price of the Optioned Shares, certificates for such shares shall be issued to the Participant. The Optioned Shares so purchased shall be fully paid and nonassessable.

5. Withholding Taxes. The Participant by this Option Agreement hereby authorizes the Company or any subsidiary bank to (i) retain and withhold from any cash amounts due or to become due from the Company to the Participant an amount equal to such taxes as may be required by any taxing authority to be withheld, or (ii) to retain and withhold the number of shares having a market value not less than the amount of such taxes and cancel any such shares so withheld, in order to reimburse the Company or any subsidiary bank, unless the Participant has made arrangements satisfactory to the Committee, regarding such payment.

6. Issuance of Shares. Promptly after receipt of such notice and payment (as set forth in Section 4, above) and of such evidence of Wisconsin residency and intent to acquire for investment as may be required by the Committee, the Company shall deliver a certificate to the Participant hereunder for the number of shares with respect to which the Option shall have been so exercised.

11. Merger or Consolidation.
