                  THIRD SUPPLEMENTAL INDENTURE, dated as of February 7, 1996,
between FIRST UNION CORPORATION, a corporation duly organized and existing under
the laws of the State of North Carolina (herein called the "Company"), having
its principal office at One First Union Center, Charlotte, North Carolina, and
HARRIS TRUST AND SAVINGS BANK, a corporation duly organized and existing under
the laws of the State of Illinois, as Trustee (herein called the "Trustee").

                  The Company has heretofore executed and delivered to The Bank
of New York (formerly Irving Trust Company) (i) an Indenture, dated as of March
15, 1986, providing for the issuance from time to time of its unsecured
debentures, notes and other evidences of indebtedness (herein and therein called
the "Securities"), to be issued in one or more series as in the Indenture
provided, (ii) a First Supplemental Indenture thereto, dated as of August 1,
1990, and (iii) a Second Supplemental Indenture thereto, dated as of November
15, 1992 (such Indenture, as so amended and supplemented, the "Indenture"). All
terms used in this Third Supplemental Indenture which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

                  The Company, The Bank of New York and the Trustee have entered
into that Instrument of Resignation, Appointment and Acceptance, dated as of
February 7, 1996, whereby The Bank of New York has resigned as trustee under the
Indenture and the Company has appointed the Trustee as trustee under the
Indenture and the Trustee has accepted such appointment as trustee under the
Indenture.

                  Section 901(10) of the Indenture provides, among other things,
that the Company, when authorized by a Board Resolution, and the Trustee, at any
time and from time to time, may enter into an indenture supplemental to the
Indenture to cure any ambiguity, to correct or supplement any provision therein
which may be inconsistent with any other provision therein, or to make any other
provisions with respect to matters or questions arising under the Indenture;
provided such action shall not adversely affect the interests of the Holders of
Securities of any series in any material respect.

                  The Company desires and has requested the Trustee to






join with it in the execution and delivery of this Third Supplemental Indenture
for the purpose of amending the Indenture in certain respects with respect to
the Securities.

                  The Company represents that all things necessary to make this
Third Supplemental Indenture a valid agreement of the Company, in accordance
with its terms, have been done.

                                    AGREEMENT

                  NOW, THEREFORE, THIS THIRD SUPPLEMENTAL INDENTURE
WITNESSETH:

                  For and in consideration of the premises contained herein, it
is mutually covenanted and agreed, for the equal and proportionate benefit of
all Holders of the Securities of any series thereof, as follows:

         its successors (whether by consolidation, merger, conversion, transfer
         of substantially all of their assets and business or otherwise)."

                  Section 102. The definition of "Corporate Trust Office" set
