Dear Messrs. Xxxxx and Xxx:

This letter sets forth the agreement between BayVanguard Bank, Sparrows Point, Maryland (the “Bank”), wholly-owned by BV Financial, Inc. (the “Company”), which in turn is the mid-tier holding company majority owned by Bay-Vanguard, MHC (the “MHC”), collectively, “Bay-Vanguard” or the “Company,” and RP^® Financial, LC. (“RP Financial”), whereby RP Financial will provide the independent conversion appraisal services in conjunction with Bay-Vanguard’s second step conversion offering.

The scope, 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 RP Financial staff members.

Description of Appraisal Services

Pursuant to this appraisal engagement, RP Financial will conduct financial due diligence of Bay-Vanguard, for the purpose of estimating the pro forma market value of the Company in accordance with the applicable regulatory appraisal guidelines. Such due diligence will include senior management interviews and reviews of historical and pro forma financial information to be included in the prospectus and other documents and records, to gain insight into the operations, financial condition, profitability, market area, risks and various internal and external factors. RP Financial will prepare a detailed written valuation report of the Company consistent with applicable regulatory appraisal guidelines and standard pro forma valuation practices. The appraisal report will include an analysis of the Company’s financial condition and operating results, as well as an assessment of the interest rate, credit, and liquidity risks. The appraisal report will incorporate an evaluation of the Company’s business strategies, recent transactions, market area, future prospects, and intended use of proceeds. RP Financial will select a peer group of relatively comparable public banking companies for the purpose of determining appropriate valuation adjustments for the Company relative to the peer group’s pricing ratios based on key fundamental differences.

We will review pertinent sections of the Company’s prospectus and conduct discussions with representatives of the Company and its other conversion advisors to obtain necessary data and information for the appraisal report, including key deal elements such as dividend policy, use of proceeds, reinvestment rate, tax rate, offering expenses, and characteristics of stock plans.

The original appraisal report will establish a midpoint pro forma market value in accordance with applicable regulatory requirements. The appraisal report may be periodically updated throughout the conversion process, and there will be at least one updated appraisal that would be prepared at the time of the closing of the stock offering to determine the number of shares to be issued in accordance with the conversion regulations. In the event of a syndicated community offering, it will be necessary to file an update in conjunction with the close of the subscription offering and prior to the pricing phase in the syndicated community offering.

RP Financial agrees to deliver the original appraisal report and subsequent updates, in writing, to the Company at the above address in conjunction with the filing of the regulatory conversion applications and amendments thereto. Subsequent updates, upon authorization by the Company, will be filed promptly as certain events occur which would warrant the preparation and filing of such appraisal updates pursuant to regulatory guidelines. 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 regarding the original appraisal and subsequent updates.

In the event of a syndicated community offering phase, RP Financial will participate in the various all hands calls regarding the offering results, pricing discussions and timing.

RP Financial will present the appraisal report, including the appraisal methodology, peer group selection and assumptions, to the Board of Directors for review. If appropriate, RP Financial will present subsequent updates to the Board. It is understood that such presentations may be made telephonically.

Fee Structure and Payment Schedule

The Company agrees to pay RP Financial fees for preparation and delivery of the original appraisal report and subsequent appraisal updates as shown below, plus reimbursable expenses.

• $15,000 upon execution of this letter of agreement engaging RP Financial’s appraisal services;

• $105,000 upon delivery of the completed original appraisal report; and

• $15,000 upon delivery of each subsequent appraisal update report required in conjunction with the regulatory application and stock offering.

The Company 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 travel, printing, communications, shipping, computer and data services, and will not exceed $10,000 in the aggregate, without the Company’s authorization to exceed this level. In the event travel is not practical or unsafe due to the COVID-19 pandemic or other reasons, RP Financial and the Company agree to make other arrangements, such as telephonic or videoconference meetings.
