ITEM 6.    INDEMNIFICATION OF DIRECTORS AND OFFICERS.

           The effect of charter, by-law, statutory and other provisions 
whereby the directors and officers of FNB may be insured or indemnified against
liability as officers and directors are set out below:

           Article IX of the Bylaws of the Corporation provides that the 
Corporation shall indemnify each director and officer of the Corporation and of
its controlled subsidiaries made or threatened to be made a party to any civil,
criminal, administrative or investigative action, suit or proceeding (whether 
brought by or in the name of the Corporation or otherwise) arising out of such
director's or officer's service to the Corporation or to another organization 
at the Corporation's request against all expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably 
incurred by such director and officer in connection with such action, suit or 
proceeding.  Indemnification shall not be made with respect to actions, suits 
or proceedings where the act or omission giving rise to the claim for 
indemnification has been determined to have constituted willful misconduct or 
recklessness or where prohibited by law.  In addition, expenses incurred by 
each director and officer in defending any such action, suit or proceeding, 
shall be paid by the Corporation in advance of the final disposition of such 
action, suit or proceeding if an undertaking (in form and scope satisfactory 
to the Corporation) shall have been furnished to the Corporation to repay 
amounts so advanced if and to the extent it shall ultimately be determined 
that such officer or director is not entitled to indemnification and certain 
other conditions shall have been satisfied.  The Corporation may purchase 
and maintain insurance, create a fund of any nature, grant a security 
interest or otherwise secure or insure in any manner its indemnification 
obligations.  



           Section 1741 of the Pennsylvania Business Corporation Law provides 
that a corporation shall (subject to the provisions described in the second 
succeeding paragraph) have the power to indemnify any person who was or is a 
party, or is threatened to be made a party, to any threatened, pending or 
completed action or proceeding, whether civil, criminal, administrative or 
investigative (other than an action by or in the right of the corporation), 
by reason of the fact that such person is or was a representative of the 
corporation, or is or was serving at the request of the corporation as a 
representative of another domestic or foreign corporation for profit or 
not-for-profit, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts 
paid in settlement actually and reasonably incurred by such person in 
connection with the action or proceeding if such person acted in good
faith and in a manner he reasonably believed to be in, or not opposed to, 
the best interests of the corporation and, with respect to any criminal 
proceeding, had no reasonable cause to believe his conduct was unlawful.  

           The termination of any action or proceeding by judgment, order, 
settlement or conviction, or upon a plea of nolo contendere or its equivalent 
shall not of itself create a presumption that such person did not act in 
good faith and in a manner which he reasonably believed to be in, or not 
opposed to, the best interests of the corporation and, with respect to any 
criminal proceeding, had reasonable cause to believe that his conduct was 
unlawful. 
          
           Section 1742 of the Pennsylvania Business Corporation Law provides 
that a corporation shall (subject to the provisions described in the succeeding
paragraph) have the power to indemnify any person who was or is a party, or 
is threatened to be made a party, to any threatened, pending or completed 
action by or in the right of the corporation to procure a judgment in its favor
by reason of the fact that such person is or was a representative of the 
corporation, or is or was serving at the request of the corporation as a 
representative of another domestic or foreign corporation for profit or 
not-for-profit, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by 
such person in connection with the defense or settlement of the action if 
such person acted in good faith and in a manner he reasonably believed to be 
in, or not opposed to, the best interests of the corporation.  Indemnification 
shall not be made in respect of any claim, issue or matter as to which such
person has been adjudged to be liable to the corporation unless and only to 
the extent that the court of common pleas of the county in which the registered 
office of the corporation is located or the court in which the action was 
brought determines upon application that, despite the adjudication of liability
but in view of all the circumstances of the case, such person is fairly and 
reasonably entitled to indemnity for such expenses that the court of common 
pleas or other court deems proper.

           Under Section 1744 of the Pennsylvania Business Corporation Law, 
any such indemnification (unless ordered by a court) shall be made by the 
corporation only as authorized in the specific case upon a determination 
that indemnification of the representative is proper in the circumstances 
because such person has met the applicable standard of conduct.  Such 
determination shall be made: 

         (1)   By the Board of Directors by a majority vote of a quorum 
     consisting of directors who were not parties to the action or
     proceeding; or

         (2)   If such quorum is not obtainable or, even if obtainable a 
     majority vote of a quorum of disinterested directors so directs, by 
     independent legal counsel in a written opinion; or

         (3)   By the shareholders.

         Notwithstanding the above, Section 1743 provides that to the extent 
that a representative of the corporation has been successful on the merits or 
otherwise in defense of any action or proceeding referred to above, or in 
defense of any claim, issue or matter therein, such person shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred 
by such person in connection therewith.



         Under Section 1745 of the Pennsylvania Business Corporation Law, 
expenses (including attorneys' fees) incurred in defending any action or 
proceeding may be paid by the corporation in advance of the final disposition
of the action or proceeding upon receipt of an undertaking by or on behalf of 
the representative to repay such amount if it is ultimately determined that 
such person is not entitled to be indemnified by the corporation.

         Section 1746 of the Pennsylvania Business Corporation Law further 
provides that the indemnification provided by Sections 1741, 1742 and 1743 
and the advancement of expenses provided by Section 1745 shall not be deemed
exclusive of any other rights to which a person seeking indemnification or 
advancement of expenses may be entitled under any bylaw, agreement, vote of 
shareholders, disinterested directors or otherwise, both as to action in his 
official capacity and as to action in another capacity while holding that 
office.  A corporation may create a fund of any nature, which may, but need 
not be, under the control of a trustee, or otherwise secure or insure in any 
manner its indemnification obligations, whether arising under or pursuant
to Section 1746 or otherwise. Indemnification pursuant to Section 1746 
shall not be made in any case where the act or failure to act giving rise 
to the claim for indemnification is determined by a court to have constituted
willful misconduct or recklessness.

         Indemnification pursuant to Section 1746 under any bylaw, agreement, 
vote of shareholders, or directors or otherwise may be granted for any action 
taken or any failure to take any action and may be made whether or not the 
corporation would have the power to indemnify the person under any other 
provision of law except as provided in such Section 1746 and whether or not 
the indemnified liability arises or arose from any threatened, pending or 
completed action by or in the right of the corporation.  Section 1746 declares 
such indemnification to be consistent with the public policy of Pennsylvania.

         The foregoing is only a general summary of certain aspects of 
Pennsylvania law dealing with the indemnification of directors and officers 
and does not purport to be complete.  It is qualified in its entirety by 
reference to the relevant statutes which contain detailed specific provisions 
regarding the circumstances under which and the person for whose benefit 
indemnification shall or may be made and accordingly are incorporated herein 
by reference.

ITEM 9.    UNDERTAKINGS.

(a)        Rule 415 Offering undertaking:

           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 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, represents a 
                     fundamental change in the information set forth in the 
                     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)(l)(i) and (a)(l)(ii) do not apply if 
the Registration Statement is on Form S-3 or Form S-8 and the information 
required to be included in a post-effective amendment by those paragraphs is 
contained in periodic reports filed by the Corporation 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 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
undertaking:

           The undersigned registrant hereby undertakes that, for purposes of 
determining any liability under the Securities Act of 1933, each filing of the 
Corporation'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)        Filing of Registration Statement on Form S-8 undertaking:

           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.



SIGNATURES

             Pursuant to the requirements of the Securities Act of 1933, 
the Corporation certifies that it has reasonable grounds to believe that it 
meets all of the requirements for filing on Form S-8 and has duly caused 
this registration statement to be signed on its behalf by the undersigned, 
thereunto duly authorized, in the City of Hermitage, Commonwealth of 
Pennsylvania, on July 6, 1998.

                SEMINOLE BANK, INC. MANAGEMENT STOCK OPTION PLAN
                ------------------------------------------------

                                     SECTION I

                                      PURPOSE
                                      -------

      The purpose of this Plan is to offer long-term incentives in addition to 
current compensation to those executive employees of the Corporation and its 
subsidiary corporations who are responsible for the successful operation, 
administration and management of the Corporation and whose continued 
contributions are important to the continued success of the Corporation.

                                     SECTION II

                                    DEFINITIONS
                                    -----------

      In this Plan, the following words and expressions shall have the meaning 
hereinafter assigned to them:

      (a)   "Board of Directors" means the Board of Directors of the 
Corporation.

      (b)   "Common Stock" means the authorized Common Stock of the Corporation 
with par value of ten cents per share.

      (c)   "Corporation" means SEMINOLE BANK, INC., a Florida corporation.

      (d)   "Disability" shall mean such incapacitation by reasons of accident 
or sickness that a Participant shall be unable to carry on substantially all 
of the normal duties of his regular occupation for the Corporation or its 
subsidiary corporations.

      (e)   "Nonqualified Stock Option" means the grant to a Participant 
pursuant to this Plan of an option to purchase shares of the Common Stock of 
this Corporation.

      (f)   "Participant" shall have the meaning assigned to that term in 
Section IV.

      (g)   "Plan" means this Management Stock Option Plan.



                                    SECTION III 

                                BOARD OF DIRECTORS
                                ------------------

        3.1     GRANT AND EXERCISE LIMITATIONS.  Subject to the provisions of 
this Plan, the Board of Directors shall have exclusive power to select the 
executive employees to be granted Management Stock Options, to determine the 
number of Management Stock Options to be granted to each such executive 
employee so selected, to determine the time or times when Management Stock 
Options will be granted, to determine the time or times, and the conditions, 
subject to which any Management Stock Options may be exercisable.

        3.2     PLAN ADMINISTRATION.  The Board of Directors shall have full 
authority and power to interpret and administer this Plan.  All decisions, 
determinations and directions made or given by the Board of Directors under 
this Plan shall be final and conclusive.

                                  SECTION IV

                                 PARTICIPANTS
                                 ------------

        4.1     PARTICIPANT.  A "Participant" shall mean an executive employee 
of the Corporation or any of its subsidiaries who shall be selected by the Board
of Directors to participate in this Plan.  No member of the Board of Directors
who is not an executive employee of the Corporation or its subsidiaries shall 
be eligible to participate in this Plan.  The Board of Directors shall be the 
sole judge in determining who shall be a Participant.  In making its 
determination, the Board of Directors shall consider the relative 
contribution of each executive employee to the profits of the Corporation or 
its subsidiaries, his loyalty, general attitude, ingenuity, initiative, and 
such other factors as the Board of Directors may deem material.

        4.2     ELIGIBILITY RULES.  The Board of Directors from time to time 
may adopt, amend, or revoke such definitions, rules and procedures as it 
may deem advisable for its own purpose to guide it in determining which of 
the executive employees of the Corporation or its subsidiaries it shall deem 
eligible to be Participants under this Plan.



                                    SECTION V

                           NONQUALIFIED STOCK OPTIONS
                           --------------------------

        5.1     OPTION CERTIFICATE.  Any Nonqualified Stock Option granted 
pursuant to this Plan shall be evidenced by a Nonqualified Stock Option 
Certificate in such form as the Board of Directors shall from time to time 
approve.  The terms, conditions and limitations upon which such Nonqualified 
Stock Option shall be granted need not appear on such Nonqualified Stock 
Option Certificate but the grant of such Nonqualified Stock Option, as 
evidenced by the Certificate issued therefor, shall be subject to such terms, 
conditions and limitations as the Board of Directors shall determine and shall 
be subject to each and every provision of this Plan.

        5.2     OPTION PRICE.  The option price per share for which any 
Nonqualified Stock Option shall be exercisable shall be set out at the 
discretion of the Board of Directors when the option is granted; however,
that the option price shall be no less than the greater of the fair market 
value or the book value of the option shares at the time the option is awarded.

        5.3     TERM OF OPTION.  Every Nonqualified Stock Option granted 
hereunder shall expire upon the expiration of the period as prescribed by the 
Board of Directors, such date herein being referred to as the "expiration date".

        5.4     EXERCISE OF OPTION.  Unless otherwise specified by the Board of 
Directors, a Nonqualified Stock Option granted hereunder may be exercised at 
any time after it has vested and prior to the expiration date.  Options 
granted to a Participant shall vest at the rate of twenty percent (20%) each 
anniversary of the option being granted, commencing with the fifth anniversary. 
Alternatively, all options granted to a Participant shall immediately vest in 
the event that substantially all of the stock or substantially all of the 
assets of the Corporation are sold either simultaneously or as part of a 
single transaction.  A Participant's options shall vest only while the 
Participant is an executive employee of the Corporation. 



        5.5     DELIVERY OF STOCK UPON EXERCISE.  Shares of Common Stock 
purchased upon the exercise of any Nonqualified Stock Option shall be paid in 
full at the time of purchase.  Nonqualified Stock Options which are 
exercisable may be exercised from time to time by written notice to the 
Corporation stating the number of shares with respect to which the option is 
being exercised and the requested time of delivery thereof, which shall be 
at least fifteen (15) days after the giving of such notice, unless an earlier 
date shall have been mutually agreed upon.  At such time, and subject to the 
provisions of paragraph 7.6, the Corporation shall, without transfer or 
issue tax to the Participant (or other person entitled to exercise such 
option), deliver to the Participant (or other person entitled to exercise such 
option) at the principal office of the Corporation, or at such other place 
as shall be mutually acceptable, a certificate or certificates for such 
shares upon payment of the option price in full by certified or cashier's 
check or the equivalent thereof acceptable to the Corporation; provided, 
however, that the time of such delivery may be postponed by the Corporation 
for such period as may be required for it with reasonable diligence to comply 
with any requirements of law.  If the Participant (or other person entitled to 
exercise the option) fails to accept delivery of and pay for all of the 
shares specified in such notice upon tender of delivery thereof, such 
person's right to exercise the Nonqualified Stock Option with respect to such 
undelivered shares may be terminated by the Board of Directors in their sole 
discretion.

        5.6     CONDITIONS PRECEDENT.  As a condition to the issuance of any 
Common Stock to a Participant hereunder, the Participant shall be required to 
comply with the requirements of paragraphs 7.6 and 7.8 thereof.

        5.7     NO DIVIDEND OR VOTING RIGHTS.  The award of a Nonqualified 
Stock Option under this Plan shall not entitle the Participant to any dividend 
or voting rights or any other rights of a shareholder with respect to the 
shares covered by such Nonqualified Stock Option.

        5.8     NUMBER OF SHARES.  The maximum number of shares for which 
Nonqualified Stock Options may be granted under the Plan shall not at any time 
exceed in the aggregate twenty-five thousand (25,000) shares of the stock of 
the Corporation.

        5.9     NO ALIENATION.  No employee of the Corporation or its 
subsidiary corporations, or any other person shall have any claim or right to 
be granted a Nonqualified Stock Option under this Plan.  The Nonqualified 
Stock Options registered in the name of any Participant shall not be subject 
to voluntary or involuntary alienation and no Participant shall have any 
right to assign, alienate, encumber, transfer, or otherwise dispose of or 
alienate any present or future right or expectancy which such Participant 
may have at any time with respect to such Nonqualified Stock Options; each 
Participant's interest therein being hereby made nonassignable and 
nontransferable, except in the event of the Participant's death as provided 
in paragraph 6.2.



                                   SECTION VI

                            CONDITION OF EMPLOYMENT
                            -----------------------
        6.1     TERMINATION OF EMPLOYMENT.  In the event that a Participant's 
employment with Corporation or its subsidiary is terminated for any reason 
other than by reason of death, disability or normal retirement as provided 
in paragraph 6.2, such Participant shall have ninety (90) days from the date 
of such termination to exercise any option to purchase Common Stock 
hereunder to the extent the Participant shall on the date of such termination
be then entitled to exercise any such option as determined under paragraph 
5.4 above.  If the Participant shall not exercise such option within said 
ninety (90) day period, such option shall be deemed to have been forfeited 
and canceled.  Any option to purchase Common Stock held by the participant 
on the date of termination of such employment which shall not then be 
exercisable in accordance with the provisions of paragraph 5.4 above shall 
be deemed forfeited and canceled.  The Participant shall have no right to 
receive any payment for or convert any part of such forfeited and canceled 
Nonqualified Stock Option into Common Stock and neither Corporation nor 
its subsidiary corporations shall be under any legal obligation whatsoever 
to Participant on account of such forfeited and canceled Nonqualified Stock 
Option.

        6.2     DEATH OR DISABILITY.  Subject to the conditions hereinafter 
provided, if a Participant's employment with the Corporation or its subsidiary 
shall terminate by reason of the death or disability (with disability being 
determined by the Board of Directors pursuant to the Social Security guidelines
for disability) of the Participant, any Nonqualified Stock Option theretofore 
granted to such Participant shall become immediately exercisable in whole or 
in part by the Participant or his legal guardian or, in the event of the 
Participant's death, such option shall be exercisable by the decedent's 
personal representative or other person to whom such Nonqualified Stock 
Option shall pass by reason of the death of the Participant, provided such 
Nonqualified Stock Option shall be exercised on or before one hundred eighty 
(180) days after termination of the Participant's employment as a result of 
retirement, death or disability.  Any option to purchase Common Stock not so 
exercised shall be deemed forfeited and canceled and neither Corporation nor 
its subsidiary corporations shall be under any legal obligation to Participant, 
his heirs or personal representative, or any other person on account of any 
such forfeited and canceled option.

        6.3     TAX MATTERS.  The grant of any Nonqualified Stock Option 
hereunder and the exercise thereof shall be subject to withholding of income,
employment and other employee withholding taxes required to be withheld by 
law.



                                 SECTION VII

                              GENERAL PROVISIONS
                              ------------------

        7.1     TERM OF PLAN.  This Plan shall become effective upon its 
adoption by the Board of Directors and shall remain in effect for a period of 
ten (10) years after the date of adoption by the Board of Directors, unless 
sooner terminated by the Board of Directors.  The termination of this Plan 
shall not affect any Nonqualified Stock Options theretofore granted under 
this Plan which have not been exercised as of the date of termination, and 
such Nonqualified Stock Options shall remain exercisable in accordance with 
their terms notwithstanding the termination of this Plan.

        7.2     NO GUARANTEE OF EMPLOYMENT.  Neither the action of the 
Corporation in establishing this Plan nor any action taken pursuant to the 
provisions hereof, nor any provision of this Plan, shall be construed as
giving any Participant the right to be retained in the employ of the 
Corporation or any of its subsidiary corporations for any period of time.

        7.3     STRICT COMPLIANCE.  No person shall have any claim to be 
granted or receive any Nonqualified Stock Option except in strict conformity 
with the provisions of this Plan and no member of the Board of Directors, or 
officer or employee of the Corporation or any of its subsidiaries, or any other 
person shall have authority to enter into any agreement with any person for 
the award or grant of a Nonqualified Stock Option or to make any 
representation or warranty with respect thereto, except in accordance with 
this Plan.

        7.4     NO LIABILITY.  No member of the Board of Directors shall have 
any liability for any decision or action taken pursuant to this Plan if made 
in good faith and the Corporation shall save, protect, indemnify and hold 
harmless each member of the Board of Directors acting in good faith pursuant 
to this Plan against any loss or expense arising therefrom to include 
reasonable attorneys' fees for all proceedings, trials and appeals.

        7.5     ADMINISTRATIVE EXPENSE.  The expense of administering this 
Plan shall be paid by the Corporation.

        7.6     SECURITIES LAW MATTERS.  The Common Stock which is the subject 
of this Plan has not been registered under either the Securities Act of 1933 or 
the Florida Securities Act and the Corporation shall not be obligated to 
register such Common Stock under such securities laws.  All Common Stock 
issued hereunder shall be endorsed to reflect that such Common Stock has not 
been registered under such securities laws.  No Common Stock acquired 
hereunder may be sold or transferred without registration under such 
securities laws, or unless sold or transferred in a transaction which is 
exempt from such registration.  As a condition precedent to the issuance of 
any Common Stock to a Participant hereunder, the Participant shall be required
to issue an investment letter in form satisfactory to legal counsel for the 
Corporation, representing among other things that the Participant is 
acquiring such shares for investment purposes only and not with a view toward
resale or distribution.  Notwithstanding anything contained in this Plan to 
the contrary, the Corporation shall not be obligated to issue any Common 
Stock to a Participant hereunder unless, at the time of such issuance, such 
Common Stock has been registered under the aforesaid securities laws or may be
issued under applicable exemptions from such registration.  Nothing herein 
contained shall require the Corporation to register such Common Stock under 
such securities laws. 



        7.7    MODIFICATION OF NUMBER OF SHARES.  Subject to the limitations 
contained in paragraph 5.8 of this Plan, in the event of a stock dividend, or 
a stock split-up, or in the event of a "corporate transaction" as defined in 
Treasury Regulation Section 1.425-1(b)(ii), any unexercised Nonqualified Stock
Option and the unexercised portion of any partially exercised Nonqualified 
Stock Option, granted prior to the date of such stock dividend, stock 
split-up, or corporate transaction, as the case may be, shall be deemed, 
without any further corporate action, to be automatically modified as 
required to equitably take into account any such stock dividend, stock 
split-up, or corporate transaction, to the extent permitted under Treasury
Regulation Section 1.425-1  et al.   The Board of Directors shall have the 
right to interpret this provision, and shall have the right to determine the 
number of shares for which any such Nonqualified Stock Option shall be 
exercisable, and shall have the right to adjust the option price per share as 
required to so equitably take into account such action to the extent 
permitted by said Treasury Regulations.  Any such determination or 
adjustment made by the Board of Directors shall be binding and conclusive.

     7.8    STOCK RESTRICTION AGREEMENT.  As a condition precedent to the 
issuance of any stock to a Participant pursuant to this Plan, the Corporation 
may require the Participant to execute and deliver to the Corporation an 
agreement restricting the transfer of such stock and granting the Corporation 
the option to repurchase such stock at an agreed or formula price in the 
event of either a proposed transfer of stock to a third party or the death, 
disability or termination of employment of the Shareholder.  Any such 
agreement shall be in such form as may be determined in the sole discretion 
of the Corporation and its shareholders. 

      The foregoing Management Stock Option Plan was adopted by resolution of 
the Board of Directors on February 14, 1996 and by resolution of Shareholders
on February 2, 1996.
