Revere Federal Savings and Loan Association

Revere, MA 02151


Ladies and Gentlemen :


Dear Sirs:

     You have  requested  our  opinion  regarding  certain  federal  income  tax
consequences of the proposed transactions (collectively,  the "Reorganization"),
more fully  described  below,  pursuant to which (i) Revere Federal  Savings and
Loan  Association  (the "Bank") will convert from a federally  chartered  mutual
savings  bank  ("Mutual  Bank") into a federally  chartered  stock  savings bank
("Stock Bank") and become the  wholly-owned  subsidiary of RFS Bancorp,  Inc., a
newly formed  federal stock  holding  company  ("Stock  Company") and (ii) Stock
Company will become a  majority-owned  subsidiary  of Revere MHC, a newly formed
federal mutual holding company ("Mutual  Company").  These  transactions and the
related sale of Common Stock, also discussed below, will be effected pursuant to
the Plan of  Reorganization  from Mutual Savings Bank to Mutual Holding  Company
and Stock  Issuance  Plan  adopted  by the Board of  Directors  of Stock Bank on
January 21, 1998 (the "Plan").  The Reorganization and its component and related
transactions  are  described  in the Plan and in the  Prospectus  filed with the
Office of Thrift  Supervision in connection with the Reorganization and proposed
sale of common stock (the "Prospectus")]. We are rendering this opinion pursuant
to Section 6 of the Plan.  All  capitalized  terms used but not  defined in this
letter shall have the meanings assigned to them in the Plan or Prospectus.







     August   , 1998                                                     Page 2.


     The Reorganization will be effected, pursuant to the Plan, as follows:

     1.  Mutual Bank will  organize  Mutual  Company,  which will  initially  be
     organized in stock form and initially  exist as Mutual Bank's  wholly-owned
     subsidiary.

     2. Mutual Company will organize two wholly-owned subsidiaries, one of which
     will be Stock  Company,  and the other of which  will be an  interim  stock
     savings bank ("Interim").

     3. The following events will occur simultaneously pursuant to the Plan: (i)
     Mutual Bank will  exchange  its charter for a federal  stock  savings  bank
     charter and thereby become Stock Bank (the "Conversion"); (ii) Interim will
     merge with and into Stock Bank with  Stock  Bank  surviving;  (iii)  Mutual
     Company will cancel its stock and exchange its charter for a federal mutual
     holding  company  charter and thereby become a mutual  holding  company the
     members  of  which  (the  "Mutual  Company  Members")  will  be the  former
     depositors  in and  borrowers  of Mutual  Bank  immediately  prior to these
     transactions  ("Mutual Bank Members").  As a mutual entity,  Mutual Company
     will not have any authorized  capital stock.  As a result of the merger and
     charter  exchanges,  Stock Bank will become a  wholly-owned  subsidiary  of
     Mutual  Company,  and the Mutual  Company  Members  will hold  interests in
     Mutual Company  comparable to the interests they  previously held in Mutual
     Bank.

     4. Mutual  Company will then  contribute  all of the stock of Stock Bank to
     Stock Company.

     As a result  of  these  transactions,  Stock  Bank  will be a  wholly-owned
subsidiary of Stock Company and Stock Company will be a wholly-owned  subsidiary
of Mutual Company.  In substance,  upon the Conversion and pursuant to the other
transactions  described  above,  the Mutual  Bank  Members  will  constructively
receive the stock of Stock Bank and will then exchange such stock for membership
interests in Mutual Company (the "Exchange").

     Simultaneously  with the  Reorganization,  Stock Company will offer to sell
additional  shares of its  common  stock  pursuant  to the Plan,  with  priority
subscription  rights granted in descending  order of priority to certain members
of Mutual Bank,  the Bank's  employee  stock  ownership  plan,  other members of
Mutual Bank and, perhaps, certain members of the general public.

     In  connection  with the opinions  expressed  below,  we have  examined and
relied upon  originals,  or copies  certified  or  otherwise  identified  to our
satisfaction,  of the Plan and the Prospectus  and of such corporate  records of
the parties to the  Reorganization as we have deemed  appropriate.  We have also
relied,  without  independent  verification,  upon the representations of Mutual
Bank  contained in the Bank's  letter to us letter dated , 1998. We have assumed
that such  representations  are true and that the parties to the  Reorganization
will  act  in  accordance  with  the  Plan.  In  addition,  we  have  made  such
investigations  of law as we have  deemed  appropriate  to form a basis  for the
opinions expressed below.







            , 1998                                                       Page 3.


     Based on and subject to the  foregoing,  it is our opinion that for federal
income tax purposes, under current law -

     (a) as regards the Conversion:

     (1)  the  Conversion  will  constitute  a   reorganization   under  section
368(a)(1)(F)  of the Code,  and the Bank (in either its status as Mutual Bank or
Stock Bank) will recognize no gain or loss as a result of the Reorganization;

     (2) the basis of each asset of Mutual  Bank held by Stock Bank  immediately
after the  Conversion  will be the same as Mutual  Bank's  basis for such  asset
immediately prior to the Conversion;

     (3) the  holding  period of each  asset of Mutual  Bank held by Stock  Bank
immediately after the Conversion will include the period during which such asset
was held by Mutual Bank prior to the Conversion;

     (4) for purposes of Code section  381(b),  Stock Bank will be treated as if
there had been no  reorganization  and,  accordingly,  the  taxable  year of the
Mutual Bank will not end on the effective date of the Reorganization and the tax
attributes of Mutual Bank (subject to application of Code sections 381, 382, and
384),  including Mutual Bank's bad debt reserves and earnings and profits,  will
be taken into account by Stock Bank as if the Reorganization had not occurred;

     (5)  Mutual  Bank  Members  will  recognize  no  gain or  loss  upon  their
constructive receipt of shares of Stock Bank common stock solely in exchange for
their interest (i.e., liquidation and voting rights) in Mutual Bank;

     (6) a Mutual Bank  Member's  basis in the shares of Stock Bank common stock
constructively  received in the Conversion  will be the same as the basis of the
Mutual Bank interest constructively surrendered in exchange therefor;

     (7) a Mutual  Bank  Member's  holding  period  for the shares of Stock Bank
common stock constructively  received in the Conversion will include the holding
period of the  Mutual  Bank  interest  constructively  surrendered  in  exchange
therefor; and

     (8) no gain or loss will be  recognized  by  depositors of Mutual Bank upon
the  issuance to them of  deposits  in Stock Bank in the same  dollar  amount as
their deposits in Mutual Bank.

     (b) as regards the Exchange:

     (9) the  Exchange  will  qualify as an exchange of property for stock under
Code section 351;

     (10) the  shareholders  of Stock Bank (the former Mutual Bank Members) will
recognize no gain or loss upon the  transfer to Mutual  Company of the shares of
Stock Bank common stock they







            , 1998                                                       Page 4.


constructively  received in the  Conversion  in exchange  for  interests  (i.e.,
liquidation and voting rights) in Mutual Company;

     (11)  the  basis  of the  interest  in  Mutual  Company  received  by  each
shareholder  of Stock Bank in exchange  for such  shareholder's  shares of Stock
Bank common stock will be equal to the basis of such shares of Stock Bank common
stock;

     (12) the holding period of the interest in Mutual Company  received by each
shareholder  of Stock Bank will, as of the date of the Exchange,  be the same as
the  holding  period of the shares of Stock Bank  common  stock  transferred  in
exchange therefor,  provided such shares of Stock Bank common stock were held as
a capital asset on the date of the Exchange;

     (13) Mutual  Company  will  recognize no gain or loss upon its receipt from
the  shareholders of Stock Bank of shares of Stock Bank common stock in exchange
for interests in Mutual Company;

     (14)  Mutual  Company's  basis for each  share of Stock Bank  common  stock
received from a shareholder  of Stock Bank in exchange for an interest in Mutual
Company  will be the  equal to the basis of such  share of  common  stock in the
hands of such Stock Bank shareholder; and

     (15) Mutual  Company's  holding  period for each share of Stock Bank common
stock  received from a shareholder  of Stock Bank in exchange for an interest in
Mutual  Company will,  as the date of the  Exchange,  be the same as the holding
period of such shares in the hands of such Stock Bank shareholder.

     (c) as regards the offering under the Stock Issuance Plan:

     (16) no gain or loss  will be  recognized  by Stock  Bank  upon the sale of
shares of Stock Bank common stock under the Stock Issuance Plan;

     (17) no gain or loss will be  recognized  by  Eligible  Account  Holders or
Supplemental   Eligible  Account  Holders  upon  the  distribution  to  them  of
nontransferable  subscription  rights to  purchase  shares of Stock Bank  common
stock under to the Stock Issuance Plan,  provided that the amount to be paid for
such shares is equal to the fair market value of such shares;

     (18) the basis to the  shareholders  of shares of Stock Bank  common  stock
purchased  under the Stock  Issuance Plan pursuant to such  subscription  rights
will be the amount paid  therefor  and the  holding  period for such shares will
begin on the date on which such subscription rights are exercised.

     In rendering our opinion in (17),  above, and our opinion regarding the tax
basis of shares of Stock  Bank  common  stock in (18),  above,  we have  relied,
without independent  verification,  on the opinion of RP Financial,  LC that the
nontransferable subscription rights have no value.

     This  opinion is given  solely for the  benefit of the parties to the Plan,
the  shareholders  of Stock  Bank and  Eligible  Account  Holders,  Supplemental
Eligible Account Holders and other investors who purchase shares pursuant to the
Stock Issuance Plan, and may not be relied upon by any other party or
