Dear Xx. Xxxxxxx:

This letter sets forth the agreement whereby Marathon Bank, Wausau, Wisconsin (“Marathon” or the “Bank”), has engaged RP^® Financial, LC. (“RP Financial”) for independent conversion appraisal services in conjunction with the minority stock offering in connection with the Bank’s proposed mutual holding company reorganization. The specific appraisal services to be rendered, along with the timing and fee structure for these appraisal services are described below. These appraisal services will be directed by the undersigned, with the assistance of other Associates.

Description of Appraisal Services

RP Financial will conduct financial due diligence, including interviews of senior management and reviews of historical and pro forma financial information and other documents and records, to gain insight into the operations, financial condition, profitability, market area, risks and various internal and external factors which will be considered in estimating the pro forma market value of the Bank in accordance with the applicable regulatory appraisal guidelines.

RP Financial will prepare a detailed written valuation report of the Bank that will be fully consistent with applicable regulatory appraisal guidelines and standard pro forma valuation practices, taking into consideration the intended minority stock offering. The appraisal report will include an analysis of the Bank’s financial condition and operating results, as well as an assessment of the Bank’s interest rate risk, credit risk and liquidity risk. The appraisal report will incorporate an evaluation of the Bank’s business strategies, market area, prospects for the future and the intended use of proceeds both in the short term and over the longer term. A peer group analysis relative to certain relatively comparable publicly-traded companies will be conducted for the purpose of determining appropriate valuation adjustments for the Bank relative to the peer group’s pricing ratios.

We will review pertinent sections of the applications and offering documents and conduct discussions with representatives of the Bank to obtain necessary data and information for the appraisal, including the impact of key deal elements on the appraised value, such as dividend policy, use of proceeds and reinvestment rate, tax rate, offering expenses, characteristics of stock plans and charitable foundation contribution (if applicable).

The original appraisal report will establish a midpoint pro forma market value in accordance with the applicable regulatory requirements. The appraisal report will provide the basis for the Bank to determine the size of the minority stock offering. The appraisal report may be periodically updated throughout the conversion process, and, in accordance with the conversion regulations, there will be at least one updated appraisal prepared at the closing of the minority stock offering to determine the number of shares to be issued.

RP Financial agrees to deliver the valuation appraisal and subsequent updates, in writing, to the Bank at the above address in conjunction with the filing of the regulatory application. Subsequent updates will be filed promptly as certain events occur which would warrant the preparation and filing of such valuation updates. Further, RP Financial agrees to perform such other services as are necessary or required in connection with the regulatory review of the appraisal and respond to the regulatory comments, if any, regarding the valuation appraisal and subsequent updates. RP Financial will also prepare the pro forma presentations for inclusion in the prospectus, reflecting the original appraisal and subsequent updates, as appropriate.

RP Financial expects to formally present the appraisal report, including the appraisal methodology, peer group selection and assumptions, to the Board of Directors of the Bank (the “Board”) for review and consideration. If appropriate, RP Financial will present subsequent updates to the Board. It is understood that this appraisal will be presented telephonically.

Fee Structure and Payment Schedule

The Bank agrees to pay RP Financial a fixed fee of $37,500 for preparation and delivery of the original appraisal report and $7,500 for each subsequent update, plus reimbursable expenses. Payment of these fees shall be made according to the following schedule:

	·	$10,000 upon execution of this letter of agreement engaging RP Financial’s appraisal services;
	·	$27,500 upon delivery of the completed original appraisal report; and,
	·	$7,500 for each valuation update that may be required, provided that the transaction is not delayed for reasons described below. It is anticipated that there will be at least one appraisal update report, specifically the update to be prepared in conjunction with the completion of the minority stock offering.

The Bank will reimburse RP Financial for reasonable out-of-pocket expenses incurred in preparation of the original appraisal and subsequent updates. Such out-of-pocket expenses will likely include data, computer, copying/printing and reasonable counsel fees and will not exceed $2,500 in the aggregate, without the Bank’s authorization to exceed this level.

In the event the Bank shall, for any reason, discontinue the MHC reorganization prior to delivery of the completed documents set forth above and payment of the respective progress payment fees, the Bank agrees to compensate RP Financial according to RP Financial’s standard billing rates for consulting services based on accumulated and verifiable time expenses, not to exceed the respective fee caps noted above, after giving full credit to the initial retainer fee. RP Financial’s standard billing rates range from $75 per hour for research associates to $450 per hour for managing directors.

If during the course of the proposed transaction, unforeseen events occur so as to materially change the nature or the work content of the services described in this contract, the terms of said contract shall be subject to renegotiation by the Bank and RP Financial. Such unforeseen events shall include, but not be limited to, material changes to the structure of the transaction such as inclusion of a simultaneous business combination transaction, material changes in the conversion regulations, appraisal guidelines or processing procedures as they relate to conversion appraisals, material changes in management or procedures, operating policies or philosophies, and excessive delays or suspension of processing of conversion applications by the regulators such that completion of the conversion transaction requires the preparation by RP Financial of a new appraisal.

Covenants, Representations and Warranties

The Bank and RP Financial agree to the following:

1.       The Bank agrees to make available or to supply to RP Financial such information with respect to its business and financial condition as RP Financial may reasonably request in order to provide the aforesaid valuation.

Reasonable time devoted by RP Financial to situations for which RP Financial is deemed entitled to indemnification hereunder, shall be an indemnifiable cost payable by the Bank at the normal hourly professional rate chargeable by such employee.

Notwithstanding anything in this agreement to the contrary, RP Financial shall notify the Bank immediately via telephone, to be followed up in writing, of any actual, suspected or threatened security breach incident involving confidential information, and shall cooperate fully in investigating and responding to each successful or attempted security breach. RP Financial will defend, indemnify and hold the Bank harmless from and against all third party claims, losses, damages and liabilities arising out of a security breach and shall pay for all costs associated with responding to such breach, including without limitation, all legal, forensic, public relations, consultancy and other expert fees incurred by Bank, the costs of any and all notifications that Bank sends to individuals whose information was affected by any incident, and the cost of an annual credit monitoring services subscription for all such individuals.

In the event the Bank elects, within seven days of the receipt of the original notice thereof, to contest such claim by written notice to RP Financial, the Bank shall not be obligated to make payments under Section 3(c), but RP Financial will be entitled to be paid any amounts payable by the Bank hereunder within five days after the final non-appealable determination of such contest either by written acknowledgement of the Bank or a decision of a court of competent jurisdiction or alternative adjudication forum, unless it is determined in accordance with Section 3(c) hereof that RP Financial is not entitled to indemnity hereunder. If the Bank does not so elect to contest a claim for indemnification by RP Financial hereunder, RP Financial shall (subject to the Bank’s receipt of the written statement and undertaking under Section 3(c) hereof) be paid promptly and in any event within thirty days after receipt by the Bank of detailed billing statements or invoices for which RP Financial is entitled to reimbursement under Section 3(c) hereof.

(c)      Subject to the Bank’s right to contest under Section 3(b) hereof, the Bank shall pay for or reimburse the reasonable expenses, including reasonable attorneys’ fees, incurred by RP Financial in advance of the final disposition of any proceeding within thirty days of the receipt of such request if RP Financial furnishes the Bank: (1) a written statement of RP Financial’s good faith belief that it is entitled to indemnification hereunder; (2) a written undertaking to repay the advance if it ultimately is determined in a final, non-appealable adjudication of such proceeding that it or he is not entitled to such indemnification; and (3) a detailed invoice of the expenses for which reimbursement is sought.
