The Employee hereby represents that he is not bound by any confidentiality agreements or restrictive covenants which restrict or may restrict his ability to perform his duties hereunder, and agrees that he will not enter into any such agreements or covenants during the term of his employment hereunder, except such restrictive covenants or confidentiality agreements as are required by the Bank and/or Company. The Employee shall report to the Chief Executive Officer (CEO), Chris Bauer. The effective date for purposes of this Agreement is July 1, 2013.

3. Location of Performance of Duties. It is anticipated that Employee will perform his job duties at the corporate offices located in Madison, Wisconsin, except to the extent his duties may from time to time require his presence at branch offices or other locations.

4. Conduct. The Employee shall at all times during his employment:

4.1 Observe and conform to all federal, state and local laws;

4.2 Comply with all Bank employment policies applicable to employees, including the Bank’s then-current Employee Handbook (the “Employee Handbook”);

4.3 Accept and carry out all reasonable directions and orders of the CEO, his designee and/or the Board of Directors;

4.4 Otherwise act in a professional manner, setting the example of excellence to the workforce, government officials and agencies, and community.

5. Reports. The Employee shall prepare any reports as requested by the CEO and/or his designee and/or the Board of Directors on a timely basis.

6. Term of Employment and Compensation.

6.1 Term of Employment. The Bank shall employ Employee for a period of one (1) year, commencing on July 1, 2013 and ending on June 30, 2014, except as otherwise provided.

6.2 Salary. The Employee’s salary shall be $240,000.00 per annum, payable by the Bank at the rate of $20,000.00 per month in accordance with the Bank’s normal payroll procedures; provided, however, that such amount may be prorated between the Bank and Company in such proportion as may be determined by their Boards of Directors to appropriately reflect the allocation of Employee’s time between them.

6.3 EESA/ARRA. The Agreement is intended to comply with rules and regulations pertaining to executive compensation under the Emergency Economic Stabilization Act of 2008 (EESA), as amended by the American Recovery and Reinvestment Act of 2009 (the ARRA) and any amendments thereto and regulations which may have impact on the Agreement, including those regulations which became effective upon issuance by the U.S. Department of Treasury as 31 C.F.R. Part 30 on or about June 15, 2009 (the “Regulations”). Effective during the period in which any obligation of the Company arising from financial assistance provided under the United States Treasury’s Troubled Assets Relief Program (TARP) remains outstanding (but not including any period during which the Federal Government only holds warrants to purchase common stock of the Company), such that the Company is subject to Section 111 of EESA (the “TARP Participation Period”), Employers shall not, and shall not be obligated to, pay or accrue any bonus, retention award or incentive compensation or make any payment for Employee’s departure from the Employers for any reason (except for payments for services performed or benefits accrued) to or for Employee to the extent prohibited by Section 111 of EESA or the Regulations. If in the opinion of tax or regulatory counsel selected by Employer

and acceptable to Employee, it is necessary to limit or reduce Employee’s compensation pursuant to this Section 6.3, the Bank shall take all reasonable steps to restructure this Agreement and Employee’s compensation and benefits in a manner intended to compensate the Employee according to the original provisions and intent of this Agreement. This restructuring may, to the extent permissible under EESA and/or the Regulations, include (a) delaying payments during the TARP Participation Period to a time when the Bank is no longer subject to Section 111 of EESA, or (b) implementing payments or programs not originally contemplated by the parties. If in the opinion of such counsel there are payments or amounts not capable of restructuring, such amounts or payments shall be deemed waived by Employee and Employee agrees to accept such waiver; provided, however, that if Employee believes such opinion to be incorrect, (A) the Bank shall pay to the Employee the maximum amount of payments and benefits which such opinion indicates there is a high probability do not result in any such payment and benefits being in violation of EESA and/or the Regulations, and (B) the Bank may request, and Employee shall have the right to demand, that Employers request a ruling from the IRS or other applicable regulatory authority as to whether the disputed payments have such consequences. Any such request for a ruling shall be promptly prepared and filed by the Bank, but in no event later than thirty (30) days from the date of the Employee’s request as referred to above, and shall be subject to Employee’s approval prior to filing, which shall not be unreasonably withheld. The Bank and Employee agree to be bound by any ruling received and to make appropriate payments to each other to reflect the impact of EESA and the Regulations on payments made or to be made as reflected by such rulings, together with interest at the applicable federal rate provided for in Section 7872(f)(2) of the Code.

In the event the Bank ceases to be subject to ARRA and/or Section 111 of EESA and the Regulations for any reason, any limitations on amounts or payments to Employee imposed by this Section 6.3 shall cease to be effective. The parties to this Agreement recognize that further regulations under AARA and EESA, in addition to the Regulations, may affect the amounts that may be paid under this Agreement and agree that, upon issuance of any such further regulations this Agreement may be modified as is in good faith deemed necessary in light of the provisions of such regulations to achieve the intent and purposes of this Agreement, and that consent to such modifications shall be unreasonably withheld.

7. Expense Reimbursement. During the term of this Agreement, the Bank shall reimburse the Employee for all reasonable and necessary out-of-pocket expenses incurred, such as, mileage for commuting at the IRS approved rate, lodging, meals and other job and travel-related expenses or other expense as determined by the Bank with the Bank’s prior written approval, by the Employee in connection with the performance of his duties hereunder, upon the presentation of proper accounts therefore in accordance with the Bank’s policies. Such reimbursement will be due within ten (10) days after the Bank’s receipt of Employee’s request for reimbursement.

8. Benefits. During the term of this Agreement, the Employee shall be entitled to the employee benefits as provided in the Employee Handbook, dated October 1, 2009 and as updated by Employers from time to time. Employee, if she satisfies the conditions for eligibility, will be eligible to receive such other benefits that are available to employees with the similar job title and job classification as Employee, including stock options and restricted stock as is authorized and approved by the Board of Directors.

If the charges in the notice are dismissed, the Bank shall (i) pay Employee all of the compensation withheld while their obligations under this Agreement were suspended, and (ii) reinstate such obligations as were suspended.

(B) If Employee is removed and/or permanently prohibited from participating in the conduct of the Employers’ affairs by an order issued under Section 8(e)(4) or Section 8(g)(1) of the Federal Deposit Insurance Act [12 U.S.C. § 1818(e)(4) or (g)(1)], all obligations of the Bank under the Agreement shall terminate as of the effective date of the order, but vested rights of the contracting parties shall not be affected.

(C) If the Bank is in default as defined in Section 3(x)(1) of the Federal Deposit Insurance Act [12 U.S.C. 1813 (x)(1)], all obligations under the Agreement shall terminate as of the date of default, but this paragraph shall not affect any vested rights of the Employee.

(D) All obligations under the Agreement shall be terminated, except to the extent determined that continuation of the contract is necessary for the Employers’ continued operations (i) by the Comptroller of the Currency (the “Comptroller”), or the Comptroller’s designee at the time the FDIC enters into an agreement to provide assistance to or on behalf of the Employers under the authority contained in Section 13(c) of the Federal Deposit Insurance Act or (ii) by the Comptroller or the Comptroller’s designee, at the time it approves a supervisory merger to resolve problems related to operation of the Employers or when the Employers are determined by the Comptroller to be in an unsafe or unsound condition. Any rights of the parties that have already vested, however, shall not be affected by such action.

(E) In the event that 12 C.F.R. § 163.39, or any successor regulation, is repealed, this Section 9(c) shall cease to be effective on the effective date of such repeal. In the event that 12 C.F.R. § 563.39, or any successor regulation, is amended or modified, this Agreement shall be revised to reflect the amended or modified provisions if: (1) the amended or modified provision is required to be included in this Agreement; or (2) if not so required, the Employee requests that the Agreement be so revised.
