Item 3.  Incorporation of Documents by Reference.

     The following documents are incorporated by reference in this Registration

          10-K for the year ended December 31, 2000;

     (2)  First Union's Quarterly Reports on Form 10-Q for the periods ended

     (3)  First Union's Current Reports on Form 8-K dated January 18, 2001,
          April 16, 2001 (as amended June 25, 2001), May 3, 2001, May 15, 2001

          filed with the Securities and Exchange Commission relating to First

Item 6.  Indemnification of Directors and Officers.

     Sections 55-8-50 through 55-8-58 of the North Carolina Business Corporation
Act contain specific provisions relating to indemnification of directors and
officers of North Carolina corporations. In general, the statute provides that
(i) a corporation must indemnify a director or officer who is wholly successful
in his defense of a proceeding to which he or she is a party because of his or
her status as such, unless limited by the articles of incorporation, and (ii) a
corporation may indemnify a director or officer if he or she is not wholly
successful in such defense, if it is determined as provided in the statute that
the director or officer meets a certain standard of conduct. However, when a
director or officer is liable to the corporation, the corporation may not
indemnify him or her. The statute also permits a director or officer of a
corporation who is a party to a proceeding to apply to the courts for
indemnification, unless the articles of incorporation provide otherwise, and the
court may order indemnification under certain circumstances set forth in the
statute. The statute further provides that a corporation may in its articles of
incorporation or by-laws or by contract or resolution

                                       2


provide indemnification in addition to that provided by the statute, subject to
certain conditions set forth in the statute.

     First Union's by-laws provide for the indemnification of First Union's
directors and executive officers by First Union against liabilities arising out
of his or her status as such, excluding any liability relating to activities
which were at the time taken known or believed by such persons to be clearly in
conflict with the best interests of First Union.

     First Union's articles of incorporation provide for the elimination of the
personal liability of each director of First Union to the fullest extent
permitted by the provisions of the North Carolina Business Corporation Act, as
the same may from time to time be in effect.

     First Union maintains directors and officers liability insurance, subject
to certain deductible amounts. In general, the policy insures (i) First Union's
directors and officers against loss by reason of any of their wrongful acts,
and/or (ii) First Union against loss arising from claims against the directors
and officers by reason of their wrongful acts, all subject to the terms and
conditions contained in the policy.

Item 9.  Undertakings.

     (a) Rule 415 offering.

          The undersigned registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
               made, a post-effective amendment to this registration statement:

               (i)   To include any prospectus required by Section 10(a)(3) of
                     the Securities Act of 1933 (as amended, the "Securities
                     Act");

               (ii)  To reflect in the prospectus any facts or events arising
                     after the effective date of the registration statement (or
                     the most recent post-effective amendment thereof) which,
                     individually or in the aggregate, represent a fundamental
                     change in the information set forth in the registration
                     statement. Notwithstanding the foregoing, any increase or
                     decrease in the volume of securities offered (if the total
                     dollar value of securities offered would not exceed that
                     which was registered) and any deviation from the low or
                     high and of the estimated maximum offering range may be
                     reflected in the form of prospectus filed with the
                     Commission pursuant to Rule 424(b) if, in the aggregate,
                     the changes in volume and price represent no more than 20
                     percent change in the maximum aggregate offering price set
                     forth in the "Calculation of Registration Fee" table in the
                     effective registration statement; and

               (iii) To include any material information with respect to the
                     plan of distribution not previously disclosed in the
                     registration statement or any material change to such
                     information in the registration statement;

          provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
          apply if the registration statement is on Form S-3, Form S-8 or Form
          F-3, and the information required to be included in a post-effective
          amendment by

                                       5


          those paragraphs is contained in periodic reports filed with or
          furnished to the Commission by the registrant pursuant to Section 13
          or Section 15(d) of the Exchange Act that are incorporated by
          reference in the registration statement.

          (2)  That, for the purpose of determining any liability under the
               Securities Act, each such post-effective amendment shall be
               deemed to be a new registration statement relating to the
               securities offered therein, and the offering of such securities
               at that time shall be deemed to be the initial bona fide offering
               thereof.

          (3)  To remove from registration by means of a post-effective
               amendment any of the securities being registered which remain
               unsold at the termination of the offering.

     (b)  Filings incorporating subsequent Exchange Act documents by reference.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (h)  Request for acceleration of effective date of filing of registration
     statement on Form S-8.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
