Dear Mr. Campanelli:

This letter sets forth the agreement between Needham Bank, Needham, Massachusetts (the “Bank”), a state-chartered co-operative bank wholly owned by NB Financial, Inc., which is a wholly owned subsidiary of NB Financial MHC (the mutual holding company), collectively “the Bank.” In this regard, the Bank has engaged RP Financial to provide the independent conversion appraisal services in conjunction with the conversion transaction. 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 a Director and/or a consulting associate.

Description of Appraisal Services

RP Financial will provide conversion appraisal services consistent with the applicable conversion regulations, regulatory appraisal guidelines and standard valuation practices. In this regard, RP Financial will provide a written pro forma valuation report of the Bank to be filed with the conversion application, interim appraisal updates as appropriate to the reflect changes in valuation prior to closing, and the required updated appraisal to set the closing value.

In conjunction with these appraisal services, RP Financial will conduct a financial due diligence, including interviews of senior management and reviews of historical and pro forma financial information, the business plan, and other documents. This review will provide RP Financial insight into the operations, financial condition, profitability, market area, risks and key internal and external factors impacting the Bank, all of which will be considered in estimating the pro forma market value. The appraisal report will include an analysis of the Bank’s financial condition and operating results, as well as an assessment of the interest rate, credit, and liquidity risks. The appraisal report will take into consideration the Bank’s business strategies, market area, prospects for the future and specified use of proceeds. A peer group analysis relative to certain relatively comparable publicly-traded banking 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 Bank’s prospectus and conduct discussions with representatives of the Bank 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 conclude with a midpoint pro forma market value in accordance with applicable regulatory requirements, which will then establish the resulting range of value for all shares as well as the offering range of value. There will be at least one updated appraisal prepared at the time of the closing of the conversion 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 all appraisal reports and updates, in writing, to the Bank at the above address. Subsequent updates, upon authorization by the Bank, 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, both Federal and state regulators, regarding the initial appraisal, the appraisal filed with the formal application and subsequent updates. In the event of a syndicated community offering phase, RP Financial will participate in the various calls regarding the offering, pricing discussions and timing.

RP Financial will formally present the appraisal report, including the appraisal methodology, peer group selection and assumptions, to the Board of Directors for review and consideration. If appropriate, RP Financial will present subsequent updates to the Board. It is understood that this appraisal may be presented either in person or telephonically.

Fee Structure and Payment Schedule

The Bank agrees to pay RP Financial fees for preparation and delivery of the initial appraisal report, the appraisal report filed with the formal application and subsequent appraisal updates as shown below, plus reimbursable expenses. Payment of these fees shall be made according to the following schedule:

· $20,000 upon execution of this letter of agreement engaging RP Financial’s appraisal services;

· $165,000 upon delivery of the appraisal report based on March 31, 2023 financial statements to accompany the formal filing of the application;

· $20,000 for preparation of the pro forma presentations for inclusion in the prospectus, reflecting the original appraisal and subsequent update; and

· $20,000 upon delivery of each subsequent appraisal update required for the regulatory application and stock offering. Under the conversion regulations a closing appraisal update is required in conjunction with the completion of the offering. In addition, there may be appraisal updates required prior to commencement of the offering if interim changes in market conditions or financial results dictate. Also, if there is a syndicated offering phase, it will be necessary to prepare an update immediately upon completion of the subscription/ community offering and prior to the commencement of the syndicated phase of the offering.

Mr. Joseph P. Campanelli

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 travel, copying/printing, shipping, computer and data services, and will not exceed

$10,000 in the aggregate, without the Bank’s authorization to exceed this level.

In the event the Bank shall, for any reason, discontinue the proposed transaction prior to delivery of the completed original appraisal report or subsequent updates and payment of the corresponding 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 applying full credit to the initial retainer fee towards such payment, together with reasonable out-of-pocket expenses, subject to the cap on such expenses as set forth above. RP Financial’s standard billing rates range from $125 per hour for research associates to $550 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.
