                  re:      FIRST UNION INSTITUTIONAL CAPITAL I

Ladies and Gentlemen:

                  We have acted as special Delaware counsel for First Union
Corporation, a North Carolina Corporation (the "Company"), and First Union
Institutional Capital I, a Delaware business trust (the "Trust"), in connection
with the matters set forth herein. At your request, this opinion is being
furnished to you.

                  For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

                  (a) The Certificate of Trust of the Trust, dated November 21,
1996 (the "Certificate"), as filed in the office of the Secretary of State of
the State of Delaware (the "Secretary of State") on November 21, 1996;

                  (b) The Trust Agreement of the Trust, dated as of November
21, 1996, among the Company, as Depositor, and the Trustee of the Trust named 
therein;

                  (c) Amendment No. 1 to the Registration Statement (the
"Registration Statement") on Form S-4, including a preliminary prospectus (the
"Prospectus") relating to the 8.04% Capital Securities of the Trust representing
undivided beneficial interests in the assets of the Trust (each, a "Capital
Security" and collectively, the "Capital Securities"), as proposed to be filed
by the Company and the Trust with the Securities and Exchange Commission on or
about January 14, 1997;
    
                  (d) The Amended and Restated Trust Agreement of the Trust,
dated as of November 27, 1996 (including Exhibits A, C and E thereto) (the
"Trust Agreement"), among the Company, as Depositor, the trustees of the Trust
named therein, and the holders, from time to time, of undivided beneficial
interests in the assets of the Trust; and
   
                  (e) A Certificate of Good Standing for the Trust, dated
January 14, 1997, obtained from the Secretary of State.
    
                  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 in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that 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 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 Capital Security is to be issued by the Trust 

(collectively, the "Capital Security Holders") of a Capital Securities 

Certificate for such Capital Security and the payment for the Capital Security
acquired by it, in accordance with the Trust Agreement and the Registration
Statement, and (vii) that the Capital Securities are issued and sold to the
Capital Security Holders in accordance with the Trust Agreement and the
Registration Statement. 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 that 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 have 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.

                  2. The Capital 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 Capital 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 Capital 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 New Capital 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,

                                                     Richards, Layton & Finger
