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.


                                                       Sincerely,


                                                       RP FINANCIAL, LC.

                                                       /s/RP FINANCIAL, LC.
