         (c)      The description of Registrant's common stock contained in
                  Registrant's registration statement on Form 8-A, filed July
                  26, 1999, and any amendment or report filed for the purpose of
                  updating such description.

         All documents filed by the registrant pursuant to Section 13(a), 13(c),
14 or 15(d) of the Securities Exchange Act of 1934, as amended, subsequent to
the date of this registration statement and prior to the filing of a

to be incorporated by reference in this registration statement and to be a part
hereof from the date of filing of such documents. Any statement contained herein
or in a document incorporated or deemed to be incorporated by reference herein
shall be deemed to be modified or superseded for purposes of this registration
statement to the extent that a statement contained herein or in any other

Item 4.           Description of Securities

         This item is not applicable.

Item 5.           Interests of Named Experts and Counsel

         The validity of original issue shares of $0.625 par value common stock
of Registrant to be issued pursuant to the Plan has been passed upon by Clyde A.
Billings, Jr., Senior Vice President and Counsel of FTNC. Mr. Billings
beneficially owns shares of FTNC common stock and holds options to purchase such
shares in an amount deemed substantial by securities regulations. On November 1,
1999, the number of shares, including options, beneficially owned by Mr.
Billings was approximately 49,100 shares.

Item 6.           Indemnification of Directors and Officers

         Tennessee Code Annotated Sections 48-18-501 through 48-18-509 authorize
a corporation to provide for the indemnification of officers, directors,
employees and agents in terms sufficiently broad to permit indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended. FTNC has adopted
the provisions of the Tennessee statute pursuant to Article Six of its Bylaws.
Also FTNC has a "Directors' and Officers' Liability Insurance Policy" which
provides coverage sufficiently broad to permit indemnification under certain
circumstances for liabilities (including reimbursement for expenses incurred)
arising under the Securities Act of 1933, as amended.



                                      II-1

   3



         Tennessee Code Annotated, Section 48-12-102, permits the inclusion in
the charter of a Tennessee corporation of a provision, with certain exceptions,
eliminating the personal monetary liability of directors to the corporation or
its shareholders for breach of the duty of care. FTNC has adopted the provisions
of the statute as Article 13 of its charter.

         The shareholders of FTNC have approved an amendment to Article Six of
the Bylaws pursuant to which FTNC is required to indemnify each director and any
officers designated by the Board of Directors, and advance expenses, to the
maximum extent not prohibited by law. In accordance with the foregoing, the
Board of Directors is authorized to enter into individual indemnity agreements
with the directors and such officers. Such indemnity agreements have been
approved for all of the directors and certain officers.

Item 9.           Undertakings

(a)      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;

                  (ii)    To reflect in the prospectus any fact 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, represents a fundamental change in the
                          information set forth in the registration statement;
                          Notwithstanding the foregoing,



                                      II-2

   4



                           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 end 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 a
                           20% change in the maximum aggregate offering price
                           set forth in the "Calculation of Registration Fee"
                           table in the effective registration statement.

                  (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 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 Securities Exchange Act of 1934 that
         are incorporated by reference in the registration statement.

                  (2)      That, for the purpose of determining any liability
                           under the Securities Act of 1933, 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)      The undersigned registrant hereby undertakes that, for purposes of
         determining any liability under the Securities Act of 1933, each filing
         of the registrant's annual report pursuant to Section 13(a) or Section
         15(d) of the Securities Exchange Act of 1934, (and, where applicable,
         each filing of an employee benefit plan's annual report pursuant to
         Section 15(d) of the Securities Exchange Act of 1934) 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.

(c)      Insofar as indemnification for liabilities arising under the Securities
         Act of 1933 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 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 Act and will be
         governed by the final adjudication of such issue.
