securities then remaining unsold, shall be deemed to be incorporated by
reference in this Registration Statement and to be part hereof from the date of

                  Registration Statement filed under Section 12 of the Exchange
                  Act, including all amendments and reports updating such

         No response is required to this item.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         The validity of the common stock registered hereby will be passed upon
by James G. Orie, General Counsel of FNB. Mr. Orie owns 781 shares of FNB common

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Florida Business Corporation Act, as amended (the "Florida Act"),
provides that, in general, a business corporation may indemnify any person who
is or was a party to any proceeding (other than an action by, or in the right
of, the corporation) by reason of the fact that he or she is or was a director
or officer of the corporation, against liability incurred in connection with
such proceeding, including any appeal thereof, provided certain standards are
met, including that such officer or director acted in good faith and in a manner
he or she reasonably believed to be in, or not opposed to, the best interests of
the corporation, and provided further that, with respect to any criminal action
or proceeding, the officer or director had no reasonable cause to believe his or
her conduct was unlawful. In the case of proceedings by or in the right of the
corporation, the Florida Act provides that, in general, a corporation may
indemnify any person who was or is a party to any such proceeding by reason of
the fact that he or she is or was a director or officer of the corporation
against expenses and amounts paid in settlement actually and reasonably incurred
in connection with the defense or settlement of such proceeding, including any
appeal thereof, provided that such person acted in good faith and in a manner he
or she reasonably believed to be in, or not opposed to, the best interests of
the corporation, except that no indemnification shall be made in


                                      II-1

<PAGE>   3
respect of any claim as to which such person is adjudged liable unless a court
of competent jurisdiction determines upon application that such person is fairly
and reasonably entitled to indemnity. To the extent that any officers or
directors are successful on the merits or otherwise in the defense of any of the
proceedings described above, the Florida Act provides that the corporation is
required to indemnify such officers or directors against expenses actually and
reasonably incurred in connection therewith. However, the Florida Act further
provides that, in general, indemnification or advancement of expenses shall not
be made to or on behalf of any officer or director if a judgment or other final
adjudication establishes that his or her actions, or omissions to act, were
material to the cause of action so adjudicated and constitute: (i) a violation
of the criminal law, unless the director or officer had reasonable cause to
believe his or her conduct was lawful or had no reasonable cause to believe it
was unlawful; (ii) a transaction from which the director or officer derived an
improper personal benefit; (iii) in the case of a director, a circumstance under
which the director has voted for or assented to a distribution made in violation
of the Florida Act or the corporation's articles of incorporation; or (iv)
willful misconduct or a conscious disregard for the best interests of the
corporation in a proceeding by or in the right of the corporation to procure a
judgment in its favor or in a proceeding by or in the right of a shareholder.

         FNB's Articles of Incorporation provide that FNB shall indemnify its
directors and officers to the fullest extent permitted by law in connection with
any actual or threatened action, suit or proceedings, civil, criminal,
administrative, investigative or other (whether brought by or in the right of
FNB or otherwise) arising out of their service to FNB or to another organization
at FNB's request, or because of their positions with FNB. The Articles further
provide that FNB may purchase and maintain insurance to protect itself and any
such director or officer against any liability, cost or expense asserted against
or incurred by him in respect of such service, whether or not FNB would have the
power to indemnify him against such liability by law or under the provisions of
this paragraph.

         FNB's Bylaws provide that to the fullest extent permitted by law, no
director of FNB shall be personally liable for monetary damages for any action
taken, or any failure to take any action.

ITEM 7.           EXEMPTION FROM REGISTRATION CLAIMED.

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 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;

                  (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 that is incorporated by reference
in the Registration Statement shall be deemed to be a new Registration Statement
relating to the securities


                                      II-3

<PAGE>   5

offered therein, and the offering of such securities at the 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.

ITEM 4.           DESCRIPTION OF SECURITIES.

         No response is required to this item.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         The validity of the common stock registered hereby will be passed upon

stock and holds options to purchase 17,382 shares of FNB common stock.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Florida Business Corporation Act, as amended (the "Florida Act"),
provides that, in general, a business corporation may indemnify any person who
is or was a party to any proceeding (other than an action by, or in the right
of, the corporation) by reason of the fact that he or she is or was a director
or officer of the corporation, against liability incurred in connection with
such proceeding, including any appeal thereof, provided certain standards are
met, including that such officer or director acted in good faith and in a manner
he or she reasonably believed to be in, or not opposed to, the best interests of
the corporation, and provided further that, with respect to any criminal action
or proceeding, the officer or director had no reasonable cause to believe his or
her conduct was unlawful. In the case of proceedings by or in the right of the
corporation, the Florida Act provides that, in general, a corporation may
indemnify any person who was or is a party to any such proceeding by reason of
the fact that he or she is or was a director or officer of the corporation
against expenses and amounts paid in settlement actually and reasonably incurred
in connection with the defense or settlement of such proceeding, including any
appeal thereof, provided that such person acted in good faith and in a manner he
or she reasonably believed to be in, or not opposed to, the best interests of
the corporation, except that no indemnification shall be made in

                                      II-1
3
respect of any claim as to which such person is adjudged liable unless a court
of competent jurisdiction determines upon application that such person is fairly
and reasonably entitled to indemnity. To the extent that any officers or
directors are successful on the merits or otherwise in the defense of any of the
proceedings described above, the Florida Act provides that the corporation is
required to indemnify such officers or directors against expenses actually and
reasonably incurred in connection therewith. However, the Florida Act further
provides that, in general, indemnification or advancement of expenses shall not
be made to or on behalf of any officer or director if a judgment or other final
adjudication establishes that his or her actions, or omissions to act, were
material to the cause of action so adjudicated and constitute: (i) a violation
of the criminal law, unless the director or officer had reasonable cause to
believe his or her conduct was lawful or had no reasonable cause to believe it
was unlawful; (ii) a transaction from which the director or officer derived an
improper personal benefit; (iii) in the case of a director, a circumstance under
which the director has voted for or assented to a distribution made in violation
of the Florida Act or the corporation's articles of incorporation; or (iv)
willful misconduct or a conscious disregard for the best interests of the
corporation in a proceeding by or in the right of the corporation to procure a
judgment in its favor or in a proceeding by or in the right of a shareholder.

         FNB's Articles of Incorporation provide that FNB shall indemnify its
directors and officers to the fullest extent permitted by law in connection with
any actual or threatened action, suit or proceedings, civil, criminal,
administrative, investigative or other (whether brought by or in the right of
FNB or otherwise) arising out of their service to FNB or to another organization
at FNB's request, or because of their positions with FNB. The Articles further
provide that FNB may purchase and maintain insurance to protect itself and any
such director or officer against any liability, cost or expense asserted against
or incurred by him in respect of such service, whether or not FNB would have the
power to indemnify him against such liability by law or under the provisions of
this paragraph.

         FNB's Bylaws provide that to the fullest extent permitted by law, no
director of FNB shall be personally liable for monetary damages for any action
taken, or any failure to take any action.

         24.1              Powers of Attorney
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 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;

                  (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 that is incorporated by reference
in the Registration Statement shall be deemed to be a new Registration Statement
relating to the securities

                                      II-3

offered therein, and the offering of such securities at the 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.
