Board of Directors
FPB Financial Corp.
300 West Morris Street
Hammond, Louisiana  70403

Gentlemen:

        You have  requested our opinion  regarding  certain  federal  income tax
consequences  of the  conversion  of  Florida  Parishes  Bank  (the  "Bank"),  a
federally  chartered mutual savings bank, to stock form (the  "Conversion").  In
the Conversion, all of the Bank's to-be-issued capital stock will be acquired by
FPB Financial  Corp.  (the  "Company"),  a newly  organized  Louisiana-chartered
corporation.  For the reasons set forth below, and based on your representations
in a letter  dated March 9, 1999  ("Representation  Letter"),  it is our opinion
that the proposed Conversion will qualify as a reorganization within the meaning
of Section  368(a)(1)(F)  of the Internal  Revenue Code of 1986, as amended (the
"Code").  Our opinion also addresses certain other income tax consequences which
follow from this conclusion.

        This  Opinion  Letter,  including  the  opinions  contained  herein,  is
governed by, and should be  interpreted  in accordance  with,  the Legal Opinion
Accord (the  "Accord") of the American Bar  Association  Section of Business Law
(1991).  As a  consequence,  it  is  subject  to  a  number  of  qualifications,
exceptions,  definitions,  limitations on coverage and other limitations, all as
more particularly  described in the Accord,  and herein, and this Opinion Letter
should be read in

conjunction with the Accord. Our opinions herein are limited to the Code and the
regulations  promulgated  thereunder (the "Subject Laws"). We express no opinion
as to other  federal  laws and  regulations  or as to laws  and  regulations  of
Louisiana or other jurisdictions or as to factual or legal matters other than as
set forth herein.

        We have  reviewed  the  Company's  Registration  Statement  on Form SB-2
relating to the proposed  issuance of up to 449,650 shares of common stock,  par
value $.01 per share ("Common  Stock"),  subject to adjustment by the Company in
connection with the Conversion,  the Prospectus  contained therein, the Articles
of Incorporation and the Bylaws of the Company, the existing mutual and proposed
stock  Charter  of the Bank,  the Plan of  Conversion  of the Bank,  the  Bank's
Application for Conversion and such other corporate  records and documents as we
have deemed  relevant and  necessary  for the purposes of this  opinion.  In our
examination of documents, we have assumed, without independent verification, the
genuineness of all signatures and the authenticity of all documents submitted to
us as originals,  the conformity to original documents of all documents to us as
certified,  conformed  or  reproduced  copies,  and  the  authenticity  of  such
originals of such latter documents.  As to matters of fact which are material to
this opinion,  we have relied upon the accuracy of the factual matters set forth
in the Company's Registration Statement on Form SB-2, the Bank's Application for
Conversion and the Representation Letter.

        The Bank is a federally  chartered  mutual  savings bank which  conducts
business from its office in Hammond,  Louisiana.  At December 31, 1998, the Bank
had total assets of approximately $41.1 million, deposits of approximately $34.1
million and equity of  approximately  $3.6  million.  The Bank is regulated  and
supervised by the Office of Thrift Supervision (the "OTS"), and its deposits are
insured by the Savings Association Insurance Fund ("SAIF"),  administered by the
Federal Deposit  Insurance  Corporation.  The Bank converted to a federal mutual
savings   bank  on  February   23,  1999.   Prior   thereto,   the  Bank  was  a
Louisiana-chartered  savings and loan  association  known as  "Florida  Parishes
Homestead Association." References herein to the Bank include the Association as
its predecessor.

        As a mutual savings bank, the Bank has no capital stock.  Each depositor
has both a deposit account in the institution and a pro rata ownership  interest
in the net worth of the  institution  based on the balance in his or her deposit
account.  This ownership  interest is tied directly to the  depositors'  deposit
accounts,  and the  depositors  ordinarily  cannot  realize  the  value of their
ownership,  except in the unlikely event that the Bank were to be liquidated. In
such event,  the depositors would share pro rata in any residual net worth after
other  claims,  including  those  of the  depositors  for the  amount  of  their
deposits, are paid.

        The  Company  is a  recently  formed  Louisiana  corporation  which will
acquire  all  of  the  to-be-  outstanding   capital  stock  of  the  Bank  upon
consummation of the Conversion and, thereby, become

a unitary savings and loan holding company. The Company will purchase all of the
capital  stock  of the  Bank  with  a  portion  of the  net  proceeds  from  the
Conversion.

        On December 8, 1998,  the Board of  Directors of the Bank adopted a Plan
of Conversion.  The purpose of the Conversion is to enable the Bank to issue and
sell shares of its capital  stock to the Company and thereby  enhance the equity
capital base of the Bank,  which will support  continuing  deposit growth of the
Bank, possible diversification or opening of branch offices, and further enhance
the Bank's  capabilities to serve the borrowing and other financial needs of the
communities  it serves.  The use of the  holding  company  format  will  provide
greater organizational flexibility and possible diversification.

        The Company is concurrently filing a Registration Statement on Form SB-2
to register its Common Stock under the  Securities Act of 1933 pursuant to which
it will offer for sale  shares of its  Common  Stock.  The Common  Stock will be
offered for sale in a  Subscription  Offering  pursuant to  subscription  rights
which will not be transferable and will be issued without payment therefor.  The
recipients  will not be  entitled to receive  cash or other  property in lieu of
such rights.  It is anticipated that any shares of Common Stock remaining unsold
after the Subscription  Offering will be sold through a Community Offering.  All
shares of Common Stock will be sold at a uniform price based upon an independent
valuation.

        The Conversion  will be effected only upon completion of the sale of all
shares of Common  Stock of the  Company  to be  issued  pursuant  to the Plan of
Conversion. Management has informed us that the Company has no plan or intention
to dispose of any shares of the capital  stock of the Bank, to cause the Bank to
be merged with any other corporation, or to liquidate the Bank.

        The  Conversion  will not affect the business of the Bank.  Mortgage and
other  loans  of  the  Bank  will  remain   unchanged   and  retain  their  same
characteristics  after the Conversion.  Management has informed us that there is
no plan or  intention  for the Bank to sell or  otherwise  dispose of any of its
assets following the Conversion,  except for dispositions in the ordinary course
of business.

        Each deposit account in the Bank at the time of the  consummation of the
Conversion  shall become,  without any action by the account  holder,  a deposit
account in the converted Bank equivalent in withdrawable  amount, and subject to
the same terms and conditions (except as to voting and liquidation  rights),  as
the  deposit  account  in the  Bank  immediately  prior  to the  Conversion.  In
addition, at the time of the Conversion,  the Bank shall establish a liquidation
account in an amount  equal to the Bank's  net worth as  reflected  in the final
prospectus  utilized  in  the  Conversion.   The  liquidation  account  will  be
maintained  for the benefit of all  Eligible  Account  Holders and  Supplemental
Eligible  Account Holders who maintain their deposit  accounts in the Bank after
the  Conversion.  Each such account  holder  will,  with respect to each deposit
account, have an inchoate interest in a portion of the liquidation account which
is the account holder's

subaccount  balance.  An account holder's  subaccount balance in the liquidation
account will be determined at the time of the  Conversion and can never increase
thereafter.  It will,  however,  be decreased to reflect subsequent  withdrawals
that reduce, as of annual closing dates, the amount in each depositor's  account
below the amount in the account at the time of the Conversion. In the event of a
complete  liquidation of the Bank, each Eligible Account Holder and Supplemental
Eligible  Account Holder will be entitled to receive a liquidation  distribution
in the amount of the balance of his or her subaccount in the liquidation account
before any  distribution  may be made with  respect to the capital  stock of the
Bank.



                                LAW AND ANALYSIS

        Section  368(a)(1)(F)  of the Code  provides  that a mere  change in the
identity, form or place of organization of one corporation, however effected, is
a reorganization.  If a transaction qualifies as an "F"-type reorganization,  it
will  generally be  nontaxable to the  corporation  and its  shareholders  under
related provisions of the Code.

        In Rev.  Rul.  80-105,  1980-1 C.B.  78, the  Internal  Revenue  Service
considered  the federal income tax  consequences  of the conversion of a federal
mutual  savings  and  loan  association  to  a  state  stock  savings  and  loan
association. The ruling concluded that the conversion qualified as a mere change
in  identity,  form of place or  organization  within  the  meaning  of  Section
368(a)(1)(F).  The rationale for this conclusion is not clearly expressed in the
ruling, but two factors are stressed.  First, the changes at the corporate level
other than the place of organization  and form of organization  were regarded as
insubstantial.  The  converted  association  continued  its business in the same
manner;  it had the same savings accounts and loans.  The converted  association
continued its membership in the Federal  Savings and Loan Insurance  Corporation
(replaced  subsequently by the SAIF) and remained  subject to the regulations of
the Federal Home Loan Bank Board, which was replaced  subsequently by the Office
of Thrift  Supervision.  Second,  the ruling states that the ownership rights of
the depositors in the mutual company are "more nominal than real."  Although the
ruling  does  not  explain  the  significance  of  this  statement,   subsequent
administrative  interpretations have indicated that the Internal Revenue Service
believes these nominal rights are preserved in the  liquidation  account that is
typically  established for the depositors'  benefit.  This approach  enables the
Internal  Revenue  Service  to  distinguish  the  tax  treatment  of  conversion
transactions from the tax treatment of acquisitive  transactions in which mutual
companies  acquire stock  companies.  See Paulsen v. Com'r, 469 U.S. 131 (1985);
Rev. Rul. 69-6 1969-1 C.B. 104.

         The Internal  Revenue  Service has  extended  the holding of Rev.  Rul.
80-105  to  transactions  similar  to the one  contemplated  by the Bank and the
Company,  in which a conversion from mutual to stock form occurs  simultaneously
with the creation of a holding company. See e.g. private letter

rulings numbered  9140014 and 9144031.  While these rulings have no precedential
value, they do indicate the current views of the Internal Revenue Service on the
issues presented. Hanover Bank v. U.S., 369 U.S. 672, 686 (1962).

        In our opinion and based on your  Representation  Letter, the conversion
of the Bank  from a  federally  chartered  mutual  savings  bank to a  federally
chartered  stock savings bank, and the sale of its capital stock to the Company,
will constitute a reorganization  within the meaning of Section  368(a)(1)(F) of
the  Code  because  the  transaction  represents  a mere  change  in the form of
organization  of a single  corporation.  There  will be no change in the  Bank's
business or operations,  nor in its loans and deposits, all of which will become
loans  and  deposits  of  the  converted  savings  bank.  The  only  significant
difference  between the assets of the Bank before and after the Conversion  will
be the infusion of new capital.  An infusion of capital occurs in all conversion
transactions,  however,  and had no effect upon the Internal  Revenue  Service's
analysis in Rev.  Rul.  80-105.  The ownership  rights of the  depositors of the
mutual savings bank, which have nominal value,  will be preserved  through their
interests in the liquidation account in the converted savings bank. This account
will be substantially the same as the liquidation account described in Rev. Rul.
80-105.

        Because the Bank's  change in form from mutual to stock  ownership  will
constitute a reorganization  under Section 368(a)(1)(F) of the Code, and neither
the Bank nor the  Company  will  recognize  any gain or loss as a result  of the
Conversion  pursuant to Section 361 of the Code and Rev. Rul. 80-105, it is also
our  opinion  that  (1) no gain or loss  will be  recognized  by the Bank or the
Company upon the  purchase of the Bank's  capital  stock by the Company;  (2) no
gain or loss will be recognized  by Eligible  Account  Holders and  Supplemental
Eligible  Account  Holders upon the issuance to them of deposit  accounts in the
Bank in its stock  form plus  their  interests  in the  liquidation  account  in
exchange   for  their   deposit   accounts  in  the  Bank;   (3)   assuming  the
non-transferable  subscription  rights to purchase  Company Common Stock have no
value, the tax basis of the depositors' deposit accounts in the Bank immediately
after the  Conversion  will be the same as the basis of their  deposit  accounts
immediately  prior  to  the  Conversion;   (4)  assuming  the   non-transferable
subscription  rights to purchase  Company  Common  Stock have no value,  the tax
basis of each  Eligible  Account  Holder's  and  Supplemental  Eligible  Account
Holder's interest in the liquidation account will be zero; and (5) the tax basis
to the  stockholders  of  the  Common  Stock  of the  Company  purchased  in the
Conversion  will be the amount paid  therefor,  and the holding  period for such
shares will begin on the date of  consummation  of the  Conversion  if purchased
through  the  exercise of  subscription  rights and on the date after the day of
purchase if purchased in the Community Offering.

        It is  further  our  opinion  that  the  Eligible  Account  Holders  and
Supplemental  Eligible  Account  Holders will  recognize  gain, if any, upon the
issuance to them of  withdrawable  savings  accounts in the Bank  following  the
Conversion, interests in the liquidation account and non-transferable

subscription  rights to purchase  Company  Common  Stock in  exchange  for their
savings  accounts and proprietary  interests in the Bank, but only to the extent
of the value, if any, of the subscription rights.

        The opinions  expressed above are limited to the income tax consequences
of the  Conversion  under the Subject Laws.  Further,  our opinions are based on
research  of  the  Code,  applicable  Treasury  Regulations,  current  published
administrative  decisions of the Internal  Revenue  Service,  existing  judicial
decisions as of the date hereof,  and your  Representation  Letter. No assurance
can  be  given  that  legislative,   administrative  or  judicial  decisions  or
interpretations  may not be  forthcoming  that  will  significantly  change  the
opinions  set forth  herein.  We express  no  opinions  other than those  stated
immediately  above as our  opinions.  We hereby  consent  to the  filing of this
opinion as an exhibit to the  Company's  Registration  Statement  and the Bank's
Application for Conversion.

                                      Very truly yours,

                                      ELIAS, MATZ, TIERNAN & HERRICK L.L.P.
