RP FINANCIAL, LC. - --------------------------------------- Financial Services Industry Consultants September 12, 2006 Board of Directors MSB Financial, MHC MSB Financial Corp. Millington Savings Bank 1902 Long Hill Road Millington, New Jersey 07946 Re: Stock Issuance Plan: MSB Financial Corp. ------------------- Members of the Boards of Directors: All capitalized terms not otherwise defined in this letter have the meanings given such terms in the plan of stock issuance (the "Plan") adopted by the Board of Directors of MSB Financial Corp. ("MSB Financial" or the "Company"). Pursuant to the Plan, MSB Financial will issue a majority of its common stock to MSB Financial, MHC and sell a minority of its stock to the public. We understand that in accordance with the Plan, subscription rights to purchase shares of common stock in the Company are to be issued to: (1) Eligible Account Holders; (2) the Employee Stock Ownership Plan; and (3) Supplemental Eligible Account Holders. Based solely upon our observation that the subscription rights will be available to such parties without cost, will be legally non-transferable and of short duration, and will afford such parties the right only to purchase shares of common stock at the same price as will be paid by members of the general public in the community offering, but without undertaking any independent investigation of state or federal law or the position of the Internal Revenue Service with respect to this issue, we are of the belief that, as a factual matter: (1) the subscription rights will have no ascertainable market value; and (2) the price at which the subscription rights are exercisable will not be more or less than the pro forma market value of the shares upon issuance. Changes in the local and national economy, the legislative and regulatory environment, the stock market, interest rates, and other external forces (such as natural disasters or significant world events) may occur from time to time, often with great unpredictability and may materially impact the value of thrift stocks as a whole or the Company's value alone. Accordingly, no assurance can be given that persons who subscribe to shares of common stock in the subscription offering will thereafter be able to buy or sell such shares at the same price paid in the subscription offering.
