Ladies and Gentlemen:

     We have  acted as  special  Delaware  counsel  for PFBI  Capital  Trust,  a
Delaware business trust (the "Trust"),  in connection with the matters set forth

of documents has been limited to the  examination  of originals or copies of the
following:

     (a) The  Certificate  of  Trust  of the  Trust,  dated  May 27,  1997  (the
"Certificate"), as filed in the office of the Secretary of State of the State of
Delaware (the "Secretary of State") on May 27, 1997;

     (b) The Trust  Agreement  of the  Trust,  dated as of May 27,  1997,  among

Securities"),  as filed by the  Company  and the Trust with the  Securities  and
Exchange Commission on May 29, 1997;

     Initially  capitalized terms used herein and not otherwise defined are used
as defined in the Trust Agreement.

     For purposes of this opinion, we have not reviewed any documents other than
the documents  listed above,  and we have assumed that there exists no provision
in any  document  that we have not reviewed  that bears upon or is  inconsistent
with the  opinions  stated  herein.  We have  conducted no  independent  factual
investigation  of our own but  rather  have  relied  solely  upon the  foregoing
documents,  the statements and  information set forth therein and the additional
matters  recited or  assumed  herein,  all of which we have  assumed to be true,
complete and accurate in all material respects.

     With  respect to all  documents  examined  by us, we have  assumed  (i) the
authenticity of all documents submitted to us as authentic  originals,  (ii) the
conformity  with the  originals  of all  documents  submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

     For purposes of this opinion,  we have assumed (i) that the Trust Agreement
constitutes  the entire  agreement among the parties thereto with respect to the
subject matter  thereof,  including with respect to the creation,  operation and
termination of the Trust,  and that the Trust  Agreement and the Certificate are
in full force and effect and have not been  amended,  (ii)  except to the extent
provided in  paragraph 1 below,  the due  creation  or due  organization  or due
formation,  as the case may be, and valid  existence  in good  standing  of each
party  to the  documents  examined  by us  under  the  laws of the  jurisdiction
governing its creation,  organization or formation,  (iii) the legal capacity of
natural persons who are parties to the documents  examined by us, (iv) that each
of the parties to the  documents  examined by us has the power and  authority to
execute and deliver,  and to perform its obligations under, such documents,  (v)
the due  authorization,  execution  and  delivery by all parties  thereto of all
documents  examined  by us,  (vi) the receipt by each Person to whom a Preferred
Security is to be issued by the Trust  (collectively,  the  "Preferred  Security
Holders") of a Preferred  Security  Certificate for such Preferred  Security and
the payment for the Preferred  Security  acquired by it, in accordance  with the
Trust Agreement and the Prospectus,  and (vii) that the Preferred Securities are
issued and sold to the Preferred  Security  Holders in accordance with the Trust
Agreement and the Prospectus. We have not participated in the preparation of the
Registration Statement and assume no responsibility for its contents.

     This opinion is limited to the laws of the State of Delaware (excluding the
securities  laws of the  State  of  Delaware),  and we have not  considered  and
express no opinion on the laws of any other jurisdiction, including federal laws
and rules and regulations  relating thereto. Our opinions are rendered only with
respect to Delaware laws and rules,  regulations and orders thereunder which are
currently in effect.

     Based upon the foregoing, and upon our examination of such questions of law
and  statutes  of the  State of  Delaware  as we hare  considered  necessary  or
appropriate,  and subject to the  assumptions,  qualifications,  limitations and
exceptions set forth herein, we are of the opinion that:

     1. The Trust has been duly created and is validly existing in good standing
as a business trust under the Delaware  Business Trust Act, 12 Del. C. Section
3801, et seq.                                                  ------
      -- ---
     2. The  Preferred  Securities  will  represent  valid  and,  subject to the
qualifications  set forth in  paragraph  3 below,  fully paid and  nonassessable
undivided beneficial interests in the assets of the Trust.

     3. The Preferred Security Holders,  as beneficial owners of the Trust, will
be  entitled  to  the  same  limitation  of  personal   liability   extended  to
stockholders  of private  corporations  for profit  organized  under the General
Corporation  Law of the State of Delaware.  We note that the Preferred  Security
Holders may be obligated to make payments as set forth in the Trust Agreement.

     We consent to the filing of this opinion with the  Securities  and Exchange
Commission as an exhibit to the Registration  Statement.  In addition, we hereby
consent to the use of our name under the heading "Validity of Securities" in the
Prospectus.  In giving the foregoing  consents,  we do not thereby admit that we
come within the category of Persons whose consent is required under Section 7 of
the  Securities  Act of 1933, as amended,  or the rules and  regulations  of the
Securities and Exchange Commission  thereunder.  Except as stated above, without
our prior  written  consent,  this opinion may not be furnished or quoted to, or
relied upon by, any other Person for any purpose.

                                            Very truly yours,


 
                                            /s/ Richards, Layton & Finger
