                          ----------------------------

                    NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
                         TO BE HELD ON AUGUST ___, 1998

                          ----------------------------

TO THE SHAREHOLDERS OF CITIZENS HOLDING CORPORATION:

      NOTICE IS HEREBY GIVEN that a special meeting of the shareholders of
Citizens Holding Corporation, a Florida corporation ("Citizens"), will be held
at 1150 Cleveland Street, Clearwater, Florida on [DAY], August ___, 1998, at
[TIME], local time, for the following purposes:

                  (1) To consider and vote upon a proposal to approve and adopt
      the Agreement and Plan of Merger, dated as of April 6, 1998, as amended on
      July 7, 1998 (the "Merger Agreement"), by and among F.N.B. Corporation, a
      Pennsylvania corporation ("FNB"), Southwest Banks, Inc., a Florida
      corporation and wholly owned subsidiary of FNB ("Southwest"), and
      Citizens, pursuant to which Citizens will be merged with and into
      Southwest, and upon consummation of the merger, except as described in the
      Proxy Statement-Prospectus, each issued and outstanding Citizens common
      share will be converted into the right to receive a number of shares of
      FNB common stock determined in accordance with a formula described in the
      Merger Agreement and further described in the Proxy Statement-Prospectus;

                  (2) To transact such other business as may properly come
      before the special meeting or any adjournments or postponements thereof.

      NOTICE OF RIGHT TO DISSENT. If Proposal 1 above is approved and the merger
is consummated, each holder of Citizens common shares would have the right to
dissent from the approval of the Merger and would be entitled to the rights and
remedies of dissenting shareholders provided in Section 607.1302 of the Florida
Statutes ("Dissent Provisions"). A copy of the Dissent Provisions is attached as
Appendix D to the Proxy Statement-Prospectus. The right of any such shareholder
to any dissenters' rights and remedies is contingent upon the consummation of
the merger. In addition, the right of any such holder to such rights and
remedies is contingent upon strict compliance with the Dissent Provisions which
require, among other things, that the shareholder must give Citizens notice of
such shareholder's intention to dissent at or prior to the special meeting and
he or she must not vote his or her respective shares in favor of the merger. FOR
A SUMMARY OF THE REQUIREMENTS OF THE DISSENT PROVISIONS, SEE "THE MERGER --
DISSENTERS' RIGHTS OF CITIZENS SHAREHOLDERS" IN THE ACCOMPANYING PROXY
STATEMENT-PROSPECTUS.

      The Merger Agreement is more completely described in the accompanying
Proxy Statement-Prospectus, and a copy of the Merger Agreement is attached as
Appendix A thereto. PLEASE REVIEW THESE MATERIALS CAREFULLY AND CONSIDER FULLY
THE INFORMATION SET FORTH THEREIN.

      Action may be taken on the above proposals at the special meeting on the
date specified above or on any date or dates to which the special meeting may be
adjourned. Only holders of record of Citizens common shares at the close of
business on ______ ___, 1998 (the "Record Date") will be entitled to notice of,
and to vote at, the special meeting and any adjournments or postponements
thereof. The affirmative vote of at least 67% of Citizens common shares
outstanding on the Record Date is required for approval of the Merger Agreement
and the transactions contemplated thereby, including the merger.

      THE BOARD OF DIRECTORS OF CITIZENS UNANIMOUSLY RECOMMENDS THAT
SHAREHOLDERS VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY.

                       JOINT PROXY STATEMENT - PROSPECTUS

                          CITIZENS HOLDING CORPORATION
                               F.N.B. CORPORATION

             Up to 1,266,960 Shares of Common Stock, $2.00 par value

       Citizens and FNB have agreed that FNB will acquire Citizens by merging
Citizens into Southwest, a subsidiary of FNB. The merger will enable Citizens'
customers to benefit from additional products and services and will enable FNB
to extend further its operations in the Florida market. The Board of Directors
of Citizens believes that the merger will permit Citizens shareholders to
participate in the enhanced prospects of the combined company.

       The Board of Directors of Citizens has determined that the merger is in
the best interest of Citizens and its shareholders. We have unanimously approved
the Merger Agreement and we recommend that you vote in favor of the Merger
Agreement and the related merger.

       The number of shares of FNB common stock you receive will depend upon the
average price of FNB common stock for a 10 day period prior to the date of the
merger. If the merger is approved and the FNB average price is between $32.50
and $36.75 per share, you will receive a number of shares of FNB common stock
for each Citizens common share you own on the date of the merger determined in
accordance with a schedule set forth in the Merger Agreement and in Appendix A
to the Proxy Statement-Prospectus. If the FNB average price is $36.75 per share
or higher, you will receive a number of shares of FNB common stock equal in
value to $62.07 per Citizens common share. If the FNB average price is $32.50
per share or lower, you will receive a number of shares of FNB common stock
equal in value to $56.16 per Citizens common share. Because no fractional shares
will be issued, you will receive a small cash payment equal to the value of any
fractional share.

       At the special meeting, shareholders of Citizens will be asked to approve
the merger. The merger cannot be completed unless holders of at least 67% of the
outstanding Citizens common stock approve it and the related Merger Agreement.
Shareholders of FNB are not required to approve the merger.

       The date, time and place of the special meeting:

                  [date & time]
                  1150 Cleveland Street
                  Clearwater, Florida  33755

       The Proxy Statement-Prospectus provides you with detailed information
about the proposed merger. We encourage you to read this entire document
carefully. In addition, you may obtain information about FNB from documents
filed with the Securities and Exchange Commission. If you have questions, you
may also call us on business days between 9:00 a.m. and 4:00 p.m. for further
information. Please ask for David P. Stone at (813) 441-3447.

       Whether or not you plan to attend the special meeting, please take the
time to vote by completing and mailing the enclosed proxy card to us. If you
sign, date and mail your proxy card without indicating how you wish to vote,
your proxy will be counted as a vote in favor of the approval of the merger and
the related Merger Agreement. If you fail to return the proxy card or to attend
the meeting and vote, the effect will be a vote against the merger.

       YOUR VOTE IS VERY IMPORTANT.

       On behalf of the Board of Directors of Citizens, we urge you to vote
"FOR" approval of the merger and the related Merger Agreement.

                                      -----------------------------------------

         This summary highlights selected information from this Proxy
Statement-Prospectus and may not contain all of the information that is
important to you. The Agreement and Plan of Merger between FNB, Southwest and
Citizens, which we refer to as the "Merger Agreement," is attached to this Proxy
Statement-Prospectus as Appendix A. To understand the merger fully and for a
more complete description of the legal terms of the merger, you should read
carefully this entire document, the Merger Agreement, and the documents we refer
you to in this Proxy Statement-Prospectus. See "Where You Can Find More
Information" (page 75). An index of defined terms appears on page 77 of this
Proxy Statement-Prospectus.

THE COMPANIES

F.N.B. Corporation
One F.N.B. Boulevard
Hermitage, Pennsylvania 16148

through its subsidiary banks and finance company. FNB provides a full range of
financial services, primarily to consumers and small- to medium-sized
businesses. As of March 31, 1998, FNB's subsidiaries had a network of 111
offices in Pennsylvania, southwestern Florida, eastern Ohio and southwestern New
York. As of March 31, 1998, on a consolidated basis, FNB had total assets of
approximately $2.8 billion and total deposits of approximately $2.4 billion. All
references herein to FNB refer to F.N.B. Corporation and its subsidiaries,
unless the context otherwise requires. For additional information regarding FNB

"INFORMATION ABOUT FNB."

Citizens Holding Corporation
1150 Cleveland Street
Clearwater, Florida 33755
(813) 441-3447

         CITIZENS. Citizens is a bank holding company. Through its subsidiary
bank, Citizens Bank & Trust, a Florida state banking corporation, Citizens
provides commercial banking services through a network of six offices in
Pinellas County, Florida. On March 31, 1998, Citizens had total assets of
approximately $121.2 million and total deposits of approximately $103.4 million.
All references to Citizens refer to Citizens Holding Corporation and its
subsidiary bank, unless the context otherwise requires. For additional
information regarding Citizens, see "THE MERGER" and "INFORMATION ABOUT
CITIZENS."

WHAT CITIZENS SHAREHOLDERS WILL RECEIVE (See page 10)

         If the merger is approved, you will receive a number of shares of FNB
common stock for each Citizens common share you own on the date of the merger.
The number of shares you will receive will depend upon the average price of FNB
common stock for a ten (10) -day period prior to the closing of the merger.
Because no fractional shares will be issued, you will receive a small cash
payment equal to the value of any fractional share.

         If the merger is approved and the FNB average price is between $32.50
and $36.75 per share, you will receive a number of shares of FNB common stock
for each Citizens common share you own on the date of the merger determined in
accordance with a schedule set forth in the Merger Agreement and in Appendix A
to the Proxy Statement-Prospectus. If the FNB average price is $36.75 per share
or higher, you will receive a number of shares of FNB common stock equal in
value to $62.07 per Citizens common share. If the FNB average price is $32.50
per share or lower, you will receive a number of shares of FNB common stock
equal in value to $56.16 per Citizens common share.




   10



         For example, if (i) you own 100 Citizens common shares, (ii) the merger
closes on August 28, 1998, and (iii) the average price of FNB common stock is
$33.625 per share, you will receive 171 shares of FNB common stock plus $23.54.

         For additional details, please review the information under the heading
"THE MERGER" beginning on page 12.

         After shareholders approve the merger and all required regulatory
approvals have been obtained, if such average market price of FNB common stock
is below $30.00 per share, FNB may choose to proceed with the merger or to
cancel the merger.

OUR REASONS FOR THE MERGER  (See pages 16-17)

         The Citizens Board of Directors believes that the terms of the Merger
Agreement and the merger are fair to, and in the best interest of, Citizens and
its shareholders. In reaching its decision, the Citizens Board of Directors
considered the following factors, among others: (a) FNB has offered a fair price
to Citizens shareholders for their Citizens common shares and their Citizens
common shares would be acquired on a tax-free basis, (b) there is no public
market for the Citizens common shares, but the FNB Common stock to be received
in the merger is traded on Nasdaq, (c) unlike Citizens, FNB pays dividends, (d)
the potential benefits to be received by Citizens' customers from the merger and
FNB's commitment to community banking, and (e) an evaluation of the potential
long term prospects of FNB.

         We believe that the financial services industry, including banking, is
becoming increasingly competitive, and that the merger will enable us to serve
our customers better than our competitors while providing our shareholders with
substantial benefits. The merger will provide opportunities for our customers to
be offered more diverse and quality products and services. Further, since FNB
subsidiaries are operated as community banks, Citizens Board of Directors also
believes that the same commitment to customer service now existing will continue
following the merger.

         In addition to better servicing its customers, we believe that Citizens
shareholders will benefit from their ownership of FNB common stock following the
merger. The FNB common stock that Citizens shareholders would receive in the
merger represents a more liquid and diversified investment than their Citizens
common shares.

         To review the reasons for the Merger Agreement and the merger in
greater detail, see pages 16-17.

OUR RECOMMENDATION TO SHAREHOLDERS (See page 10)

         The Citizens Board of Directors believes that the merger is in your
best interest and unanimously recommends that you vote FOR the proposal to
approve the Merger Agreement and the related merger.

SPECIAL MEETING (See pages 9-11)

         The special meeting of Citizens shareholders will be held at __________
on , 1998 at . At the special meeting, Citizens shareholders will be asked to
approve the Merger Agreement and the related merger.

REQUIRED VOTE

         The Merger Agreement must be approved by the holders of 67% of all
outstanding Citizens common shares. Directors and executive officers of Citizens
currently control approximately 28.8% of the outstanding common shares entitled
to vote at the special meeting. Shareholders of FNB are not required to approve
the merger.



                                        2


   11



OWNERSHIP OF FNB AFTER THE MERGER

         Assuming the average price of FNB common stock is $33.625, as discussed
above, FNB will issue up to 1,162,057 shares of its stock to Citizens
shareholders in connection with the merger, which will constitute approximately
6.9% of the outstanding stock of FNB after the merger (assuming 16,869,602
shares of FNB common stock outstanding immediately prior to the effective time
of the merger). The shares will be listed for trading on the Nasdaq National
Market.

MANAGEMENT AND OPERATIONS AFTER THE MERGER

         After the merger takes place, Citizens Bank & Trust will be merged into
First National Bank of Florida, a banking subsidiary of Southwest. Current
members of Citizens Board of Directors will become members of the Board of
Directors of First National Bank of Florida.

OPINION OF FINANCIAL ADVISER (See page 17)

         We asked our financial advisers, Allen C. Ewing & Co., for advice on
the fairness of the amount that FNB is offering to Citizens shareholders in the
merger. Our advisers performed a number of analysis in which they compared the
companies' historical stock prices and other measures of performance, compared
the financial terms of the merger to those of other publicly announced
transactions, and estimated the relative values of FNB and Citizens based on
past and anticipated future performance and the benefits that could be expected
from the merger. Ewing delivered its written opinion, dated May 15, 1998, that
the merger consideration is fair to Citizens shareholders from a financial point
of view. Ewing reconfirmed that opinion on July 6, 1998. This opinion is
attached as Appendix C to the Proxy Statement-Prospectus.

CONDITIONS TO THE MERGER (See page 21)

         To complete the merger, a number of conditions must be satisfied in
addition to obtaining the vote of our shareholders, including the following:

       - no law or injunction may effectively prohibit the merger;
       - we must receive all necessary approvals of governmental authorities;
       - we must receive legal opinions that the merger will be treated as a tax
         free reorganization under the Internal Revenue Code; and
       - FNB's independent accountants must provide a letter which supports that
         the merger can be accounted for as a pooling-of-interests.

TERMINATION OF THE MERGER (See page 24)

         In addition to FNB's right to terminate the Merger Agreement if FNB's
stock price falls below the agreed minimum, FNB and Citizens can agree jointly
to terminate the Merger Agreement without completing the merger, and either FNB
or Citizens can terminate the merger if, among other reasons, any of the
following occurs:

       - the merger is not completed by December 31, 1998;
       - the merger is not approved by the Citizens shareholders;
       - a court or other governmental authority permanently prohibits the 
         merger; or
       - the other party breaches or materially fails to comply with any of its
         representations or warranties or obligations under the Merger
         Agreement.



                                        3


   12



AMENDMENT, WAIVER AND EXTENSION OF THE MERGER AGREEMENT (See page 24)

         The Boards of Directors of Citizens and FNB may amend the Merger
Agreement at any time before the merger actually takes place, and may agree to
extend the time within which any action required by the Merger Agreement is to
take place. However, if an amendment would change the amount or form of what
Citizens shareholders would receive in the merger, the amendment will have to be
approved by our shareholders.

REGULATORY APPROVALS (See page 33)

         The merger is subject to the approval of the Federal Reserve Board and
the Office of the Comptroller of the Currency. We may not consummate the merger
until expiration of all applicable waiting periods following such approvals. If
the Federal Reserve Board and the Office of the Comptroller of the Currency
approve the merger, the United States Department of Justice has 15 days in which
to challenge such approvals on antitrust grounds. Some of these governmental
authorities may impose conditions for granting approval.

         FNB and Citizens have filed all required applications for regulatory
review and approval or notice in connection with the merger. There can be no
assurance that such approvals will be obtained or as to the date of any such
approvals.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES (See page 25)

         The merger is structured so that Citizens shareholders will not
recognize any gain or loss for federal income tax purposes in the merger, except
for taxes payable because of cash received by Citizens shareholders instead of
fractional shares of FNB or pursuant to the exercise of dissenters' rights as
described below.

ACCOUNTING TREATMENT (See page 32)

         FNB plans to account for the merger as a pooling-of-interests under
generally accepted accounting principles ("GAAP"). In the event the total number
of fractional shares, dissenters' shares and treasury shares exceeds 10% of the
total number of shares of FNB common stock issued in the merger, FNB will not be
permitted to account for the merger as a pooling-of-interests.

STOCK OPTION AGREEMENT (See page 27)

         As a condition with the Merger Agreement, Citizens granted FNB an
option to purchase up to 144,292 Citizens common shares at an exercise price of
$35.00 per share. FNB may exercise this option only if certain events occur that
are ordinarily associated with another party attempting to "break up" the merger
and acquire a substantial portion or all of Citizens; as of this date, none of
those events has occurred. The stock option, if exercised, would equal 19.9% of
the total number of outstanding Citizens common shares as of its date of
exercise and after giving effect to its exercise. The purpose of the stock
option is to increase the likelihood that the merger will occur by making it
more difficult for another party to acquire Citizens.

DISSENTERS' RIGHTS OF CITIZENS (See page 31)

         Holders of Citizens common shares who do not vote in favor of the
merger and who follow certain procedures set forth under Florida law will be
entitled to dissenters' rights under Florida law, through which they may receive
a cash payment for the fair value of their Citizens common shares.

CERTAIN DIFFERENCES IN THE RIGHTS OF SHAREHOLDERS (See pages 63-71)

         Once the merger occurs, Citizens shareholders will automatically become
shareholders of FNB and their rights will be governed by Pennsylvania law rather
than Florida law and FNB's corporate governing documents, including its articles
of incorporation and bylaws.

RECENT FNB ACQUISITION ACTIVITY

         On January 21, 1997, FNB acquired Southwest, a Florida corporation and
registered bank holding company, with banking subsidiaries located in Naples and
Cape Coral, Florida, with assets of approximately $529 million. On April 18,
1997, FNB acquired West Coast Bancorp, Inc., a Florida corporation and
registered bank holding company located in Cape Coral, Florida, with assets of
approximately $181 million. On October 17, 1997, FNB acquired Indian Rocks State
Bank (which was subsequently converted to a national bank and renamed First
National Bank of Florida) located in Largo, Florida with assets of approximately
$81 million. On November 20, 1997, FNB acquired Mercantile Bank of Southwest
Florida, a Florida state bank located in Naples, Florida with assets of
approximately $122 million. On January 20, 1998, FNB acquired West Coast Bank, a
Florida state bank located in Sarasota, Florida with assets of approximately
$107 million. On May 29, 1998, FNB acquired Seminole Bank, a Florida state bank
located in Seminole, Florida with assets of approximately $91 million.

FUTURE FNB ACQUISITION ACTIVITY

         As part of its growth strategy, FNB may acquire other banking or thrift
institutions to expand or strengthen its market position. Risks associated with
this strategy include, but are not limited to, FNB paying too high a price for
future acquisitions or failing properly to integrate and manage new operations.
Future acquisitions may be dilutive to shareholders.

RECENT STOCK DIVIDEND

         On April 9, 1998, the FNB Board of Directors declared a 5% common stock
dividend which was paid on May 24, 1998 to shareholders of record on April 20,
1998. This action represented the 26th consecutive year that FNB has provided a
stock dividend to its common shareholders. The number of FNB shares you receive
in the merger will not change as a result of this stock dividend.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

         This Proxy Statement-Prospectus contains forward-looking statements
that are subject to risks and uncertainties. Forward-looking statements include
statements preceded by, followed by or including words such as "believes,"
"anticipates," "plans," "expects" and similar expressions. For those statements,
FNB claims the protection of the safe harbor for forward-looking statements
contained in the Private Securities Litigation Reform Act of 1995. You should
understand that the following important factors, in addition to those discussed
elsewhere in this document and the documents FNB incorporates by reference,
could affect the future results of FNB and could cause those results to differ
materially from those expressed in FNB's forward-looking statements: FNB may not
fully realize anticipated operating efficiencies; FNB may lose deposits,
customers or revenue after the merger; competitive pressure in the banking
industry, negative changes in general economic conditions, including year 2000
related issues, or changes in banking regulation could affect operations; and
changes in interest rates could reduce our operating margins.

SHARE INFORMATION AND MARKET PRICES (See page 35)

         Until June 15, 1997, the FNB common stock traded on the Nasdaq SmallCap
Market under the trading symbol "FBAN." Since June 16, 1997, the FNB common
stock has traded on the Nasdaq National Market under the same trading symbol. As
of June 8, 1998, there were 16,916,432 shares of FNB common stock outstanding
held by approximately 6,400 holders of record. As of _________, 1998, the record
date for voting on the merger, there were 580,795 Citizens common shares
outstanding held by 201 holders of record.

         After giving effect to the 5% stock dividend paid on May 24, 1998, the
last sale price reported by the Nasdaq National Market for shares of FNB common

COMPARATIVE UNAUDITED PER SHARE DATA

         The following table sets forth selected comparative per share data for
each of FNB and Citizens on an historical basis, for FNB on a supplemental basis
giving effect to the acquisition of Seminole Bank, which has been accounted for
as a pooling-of-interests, and selected unaudited pro forma comparative per
share data assuming the merger had been consummated and FNB, Seminole and
Citizens had been combined as of the beginning of the earliest period presented
for earnings per share and dividends per share and as of the end of the period
presented for book value per share. The unaudited pro forma financial data have
been prepared giving effect to the merger as a pooling-of-interests. For a
description of the effect of pooling-of-interests method of accounting on the
merger and the historical financial statements of FNB, see "THE MERGER --
Accounting Treatment."

         The comparative per share data presented are based on and derived from,
and should be read in conjunction with, the supplemental consolidated financial
statements and the related notes thereto of FNB included in FNB's Current Report
on Form 8-K dated July 6, 1998, incorporated herein by reference, and of
Citizens, which are included herein. The pro forma amounts are presented for
comparative purposes only and, therefore, are not necessarily indicative of the
operating results and financial position that might have been achieved had the
merger occurred as of an earlier date, nor are they necessarily indicative of
operating results and financial position that may occur in the future. All per
share data has been adjusted to reflect the FNB 5% stock dividend paid on May
24, 1998.

SELECTED FINANCIAL DATA

         The following tables present summary selected financial data for FNB,
on a supplemental basis giving effect to the acquisition of Seminole Bank by
FNB, which has been accounted for as a pooling-of-interests and for Citizens on
an historical basis. For a description of the effect of pooling-of-interests
accounting on the merger and the historical financial statements of FNB, see

unaudited interim financial statements of FNB for the three-month periods ended
March 31, 1997 and 1998 and the related notes thereto. The Citizens summary
selected financial data for the fiscal years 1993 through 1998 and the interim
periods are derived from the financial statements of Citizens. All FNB per share
data have been adjusted to reflect the FNB 5% stock dividend paid on May 24,
1998. See "WHERE YOU CAN FIND MORE INFORMATION."

       THE SPECIAL MEETING OF SHAREHOLDERS OF CITIZENS HOLDING CORPORATION

GENERAL

         This Proxy Statement-Prospectus is first being furnished to the holders
of common shares, par value $0.10 per share ("Citizens Common Shares"), of
Citizens Holding Corporation ("Citizens") on or about [ , 1998], and is
accompanied by the Notice of Special Meeting and a form of proxy that is
solicited by the Citizens Board of Directors ("Citizens Board") for use at the
special meeting ("Special Meeting") of shareholders of Citizens to be held at
1150 Cleveland Street, Clearwater, Florida 33755, on [ ], [ , 1998], at [time],
local time, and at any adjournments or postponements thereof. The purpose of the
Special Meeting is to take action with respect to the approval of the Merger
Agreement and the transactions contemplated thereby.

VOTING AND REVOCATION OF PROXIES

         A shareholder of Citizens may use the accompanying proxy if such
shareholder is unable to attend the Special Meeting in person or wishes to have
his or her shares voted by proxy even if such shareholder does attend the
meeting. A shareholder may revoke any proxy given pursuant to this solicitation
by delivering to the Corporate Secretary of Citizens, prior to or at the Special
Meeting, a written notice revoking the proxy or a duly executed proxy relating
to the same shares bearing a later date, or by attending the Special Meeting and
voting in person at the Special Meeting. Attendance of a shareholder at the
Special Meeting will not, in and of itself, constitute a revocation of the
proxy. All written notices of revocation and other communications with respect
to the revocation of Citizens proxies should be addressed to Citizens Holding
Corporation, 1150 Cleveland Street, Clearwater, Florida 33755, Attention:
Corporate Secretary. For such notice of revocation or later proxy to be valid,
however, it must actually be received by Citizens prior to the vote of the
shareholders. All shares represented by valid proxies received pursuant to this
solicitation, and not revoked before they are exercised, will be voted in the
manner specified therein. If no specification is made, the proxies will be voted
FOR approval of the Merger Agreement. The Citizens Board is unaware of any other
matters that may be presented for action at the Special Meeting. If other
matters do properly come before the Special Meeting, however, it is intended
that shares represented by proxies in the accompanying form will be voted or not
voted by the persons named in the proxies in their discretion.

SOLICITATION OF PROXIES

         Solicitation of proxies may be made in person or by mail, telephone, or
facsimile, or other form of communication by directors, officers, and employees
of Citizens, who will not be specially compensated for such solicitation.
Nominees, fiduciaries, and other custodians will be requested to forward
solicitation materials to beneficial owners and to secure their voting
instructions, if necessary, and will be reimbursed for the expenses incurred in
sending proxy materials to beneficial owners.

         No person is authorized to give any information or to make any
representation not contained in this Proxy Statement-Prospectus and, if given or
made, such information or representation should not be relied upon as having
been authorized by Citizens, FNB, or any other person. The delivery of this
Proxy Statement-Prospectus shall not, under any circumstances, create any
implication that there has been no change in the business or affairs of Citizens
or FNB since the date of the Proxy Statement-Prospectus.

         All costs of solicitation of proxies from Citizens shareholders will be
borne by Citizens; provided, however, that FNB and Citizens have each agreed to
pay one-half of the printing costs of this Proxy Statement-Prospectus and
related materials.

RECORD DATE AND VOTING RIGHTS

         The Citizens Board has fixed the close of business on [ , 1998] as the
record date (the "Record Date") for the determination of shareholders of
Citizens entitled to receive notice of and to vote at the Special Meeting. At
the close of business on the Record Date, there were outstanding 580,795
Citizens Common Shares held by approximately 201 holders of record. Each
Citizens Common Share outstanding on the Record Date is entitled to one vote as
to (i) the approval of the Merger Agreement and the transactions contemplated
thereby and (ii) any other proposal that may properly come before the Special
Meeting.

         As of the Record Date, approximately 167,454 shares, or 28.8% of
Citizens Common Shares entitled to vote at the Special Meeting were beneficially
held by directors and executive officers of Citizens. The banking subsidiary of
Citizens, in a fiduciary capacity for third parties, does not have sole or
shared voting power as to any Citizens Common Shares.

         Under the Articles of Incorporation of Citizens (the "Citizens
Charter"), the affirmative vote of 67% of the Citizens Common Shares issued and
outstanding as of the Record Date is required in order to approve the Merger
Agreement and the transactions contemplated thereby, including the merger. Since
approval of the Merger Agreement requires the affirmative vote of at least 67%
of the outstanding Citizens Common Shares, the failure to vote the shares in
favor of the merger for any reason whatsoever - whether by withholding the vote,
by abstaining, or by causing a broker non-vote - will have the same effect as a
vote cast opposing the merger.

         A broker non-vote generally occurs when a broker who holds shares in
street name for a customer does not have the authority to vote on certain
non-routine matters because its customer has not provided any voting
instructions with respect to the matter.

         BECAUSE APPROVAL OF THE MERGER AGREEMENT REQUIRES THE AFFIRMATIVE VOTE
OF 67% OF ALL THE VOTES ENTITLED TO BE CAST AT THE SPECIAL MEETING BY HOLDERS OF
THE ISSUED AND OUTSTANDING CITIZENS COMMON SHARES, ABSTENTIONS AND BROKER
NON-VOTES WILL HAVE THE SAME EFFECT AS NEGATIVE VOTES. ACCORDINGLY, THE CITIZENS
BOARD URGES ITS SHAREHOLDERS TO COMPLETE, DATE, AND SIGN THE ACCOMPANYING PROXY
AND RETURN IT PROMPTLY IN THE ENCLOSED, POSTAGE-PAID ENVELOPE.

         In order to take action on any other matter submitted to shareholders
at a meeting where a quorum is present, the votes cast in favor of the action
must exceed the votes cast opposing the action, unless the articles of
incorporation or state law requires a greater number of votes. All abstentions
and broker non-votes will be counted as present for purposes of determining the
existence of a quorum; but since they are neither votes cast in favor of, nor
votes cast opposing, a proposed action, abstentions and broker non-votes
typically will have no impact on the outcome of the matter and will not be
counted as a vote cast on such matters.

RECOMMENDATION OF THE CITIZENS BOARD

         THE CITIZENS BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
THE TRANSACTIONS CONTEMPLATED THEREBY, BELIEVES THAT THE MERGER IS IN THE BEST
INTERESTS OF CITIZENS AND ITS SHAREHOLDERS, AND RECOMMENDS THAT THE
SHAREHOLDERS OF CITIZENS VOTE "FOR" APPROVAL OF THE MERGER AGREEMENT.

         In the course of reaching its decision to approve the Merger Agreement
and the transactions contemplated thereby, the Citizens Board, among other
things, consulted with its legal advisers regarding the legal terms of the
Merger Agreement and with its financial adviser, Allen C. Ewing & Co., as to the
fairness, from a financial point of view, of the consideration to be received by
the holders of Citizens Common Shares. For a discussion of the factors
considered by the Citizens Board in reaching its conclusion, see "THE MERGER --
Background of and Reasons for the Merger."



                                       10


   19



         Citizens shareholders should note that certain members of management
and directors of Citizens have certain interests in and may derive certain
benefits as a result of the merger. See "THE MERGER -- Interests of Certain
Persons in the Merger."

         Pursuant to the terms of the Merger Agreement, the members of the
Citizens Board will vote their shares in favor of the Merger Agreement and the
transactions contemplated thereby at the Special Meeting.

                      CITIZENS SHAREHOLDERS SHOULD NOT SEND
                 ANY STOCK CERTIFICATES WITH THEIR PROXY CARDS.

                                   THE MERGER

         The following summary of certain terms and provisions of the Merger
Agreement and Stock Option Agreement is qualified in its entirety by reference
to the Merger Agreement and Stock Option Agreement, which are incorporated
herein by reference and, with the exception of certain exhibits thereto, are
included as Appendix A and Appendix B, respectively, to this Proxy
Statement-Prospectus. All shareholders are urged to read the Merger Agreement,
Stock Option Agreement, and the other Appendices hereto in their entirety.

DESCRIPTION OF THE MERGER

         At the Effective Time (defined below), Citizens will be merged with and
into Southwest Banks, Inc. ("Southwest"), which will be the surviving entity and
a 100% controlled subsidiary of F.N.B. Corporation ("FNB" or the "Registrant").
The Southwest Articles of Incorporation ("Southwest Charter") and the Southwest
Bylaws in effect at the Effective Time will continue to govern Southwest until
amended or repealed in accordance with applicable law. The merger is subject to
the approval of the Federal Reserve Board and the Office of the Comptroller of
the Currency. See "-- Bank Regulatory Matters." Citizens Bank & Trust, a Florida
banking corporation and a wholly owned subsidiary of Citizens (the "Bank"), will
be merged into First National Bank of Florida, a wholly owned subsidiary of
Southwest.

         At the Effective Time, each Citizens Common Share outstanding
immediately prior to the Effective Time (other than shares held by Citizens,
FNB, or any of their subsidiaries, in each case, other than in a fiduciary
capacity or as a result of debts previously contracted) will be converted
automatically into the right to receive a number of shares, subject to possible
adjustment as described below (the "Exchange Ratio"), of FNB common stock, par
value $2.00 ("FNB Common Stock"), with such number of shares to be determined by
reference to the average of the high and low prices of the FNB Common Stock for
a ten (10) -day period generally ending five days prior to closing of the merger
(the "FNB Average Price"). If the FNB Average Price is greater than $32.50 but
less than $36.75 per share, then the Exchange Ratio shall be determined by
reference to the Exchange Ratio Table set forth as Exhibit "A" to Amendment No.
1 to the Merger Agreement, which is attached hereto as Appendix A. Once
determined, the FNB Average Price will be rounded to the nearest $.125 and the
Exchange Ratio determined by the corresponding number in the Exchange Ratio
Table. If however, the FNB Average Price is equal to or greater than $36.75 per
share, then the Exchange Ratio shall equal the quotient, rounded to the third
decimal place, obtained by dividing 62.07 by the FNB Average Price (in order to
provide a number of shares of FNB Common Stock equal in value to $62.07 per
Citizens Common Share). If the FNB Average Price is equal to or less than $32.50
per share, then the Exchange Ratio shall equal the quotient, rounded to the
third decimal place, obtained by dividing 56.16 by the FNB Average Price (in
order to provide a number of shares of FNB Common Stock equal in value to $56.16
per Citizens Common Share).

         The Merger Agreement provides that the Exchange Ratio may be adjusted
to prevent dilution in the event FNB changes the number of shares of FNB Common
Stock issued and outstanding prior to the Effective Time as a result of a stock
split, stock dividend, recapitalization, reclassification, or similar
transaction (other than the 5% stock dividend (the "FNB Stock Dividend") paid on
May 24, 1998 to FNB shareholders of record on April 20, 1998). At the Effective
Time, any Citizens Common Shares held by Citizens, FNB, or any of their
subsidiaries, in each case, other than in a fiduciary capacity or as a result of
debts previously contracted, will be canceled and retired without consideration
being paid. Citizens has represented that, as of the Effective Time, there will
be no more than 676,795 Citizens Common Shares issued and outstanding. Following
the Effective Time and assuming that 676,795 Citizens Common Shares are
outstanding at the Effective Time at an FNB Average Price of $33.625 per share
and a corresponding Exchange Ratio of 1.717, the former shareholders of Citizens
would own 1,162,057 shares, or approximately 6.9%, of the then outstanding FNB
Common Stock assuming 16,869,602 shares of FNB Common Stock outstanding
immediately prior to the Effective Time). The number of shares of FNB Common
Stock to be issued in the merger will be reduced if fewer than 676,795 Citizens
Common Shares are outstanding immediately prior to the Effective Time. To the
extent that all existing Citizens Options (defined below) are not exercised in
full prior to the Effective Time, the number of Citizens Common Shares
outstanding will be less than 676,795. As of the Record Date, there were 580,795
Citizens Common Shares outstanding. However, if the FNB Average Price is less
than $30.00 per share, FNB will not be required to consummate the merger, and,
at its option, may terminate the Merger Agreement.



                                       12


   21



         No fractional shares of FNB Common Stock will be issued in the merger.
Instead, each holder of Citizens Common Shares who would otherwise have been
entitled to receive a fraction of a share of FNB Common Stock (after taking into
account all certificates delivered by such holder) will receive, in lieu
thereof, cash (without interest) in an amount equal to such fractional part of a
share of FNB Common Stock multiplied by the closing trade price of one share of
FNB Common Stock as reported by the Nasdaq National Market on the last trading
preceding the closing of the merger (or, if not so reported, by any other
authoritative source selected by FNB). No such holder will be entitled to
dividends, voting rights, or any other rights as a shareholder in respect of any
fractional shares. See "-- Exchange of Certificates."

         The shares of FNB capital stock outstanding immediately prior to the
merger will continue to be outstanding after the Effective Time.

CONVERSION OF CITIZENS OPTIONS

         Options (the "Citizens Options") issued by Citizens to certain officers
and former and current directors to purchase an aggregate of 96,000 Citizens
Common Shares were outstanding as of the Record Date. To the extent that
Citizens Common Shares are issued pursuant to the exercise of Citizens Options
in accordance with their terms prior to the Effective Time, they will be
converted into FNB Common Stock in the same manner as other Citizens Common
Shares. At the Effective Time, each Citizens Option that has not expired and
remains outstanding at the Effective Time, shall be converted into and become an
option to purchase shares of FNB Common Stock, and FNB shall assume each such
Citizens Option in accordance with the stock option agreement by which it is
evidenced (collectively, the "Citizens Stock Plans"), except that, from and
after the Effective Time, (i) FNB and its compensation committee shall be
substituted for Citizens and its compensation committee (including, if
applicable, the entire Citizens Board) administering such Citizens Stock Plan,
(ii) each Citizens Option assumed by FNB may be exercised solely for shares of
FNB Common Stock, (iii) the number of shares of FNB Common Stock subject to such
Citizens Option will be equal to the number of Citizens Common Shares subject to
such Citizens Option immediately prior to the Effective Time multiplied by the
Exchange Ratio, with cash being paid in lieu of any resulting fraction of a
share of FNB Common Stock equal to the product of such fraction and the
difference between the market value of one share of FNB Common Stock and the per
share exercise price of such option, warrant or other right to purchase shares
of FNB Common Stock, and (iv) the per share exercise price under each such
Citizens Option will be adjusted by dividing the per share exercise price under
each such Citizens Option by the Exchange Ratio and rounding down to the nearest
cent. Notwithstanding the provisions of clauses (iii) and (iv) of the preceding
sentence, each Citizens Option which is an incentive stock option shall be
adjusted as required by Section 424 of the Internal Revenue Code of 1986, as
amended (the "Code"), so as not to constitute a modification, extension, or
renewal of the option within the meaning of Section 424(h) of the Code. FNB has
agreed to take all necessary steps to effectuate the foregoing provisions.

         As soon as practicable after the Effective Time, FNB will deliver to
the holders of each Citizens Option an appropriate notice setting forth such
participant's rights pursuant thereto and the grants pursuant to such Citizens
Option shall continue in effect on the same terms and conditions (subject to the
adjustments described in the above paragraph after giving effect to the merger),
and FNB will comply with the terms of each Citizens Option to ensure, to the
extent required thereby, that Citizens Options which qualified as incentive
stock options prior to the Effective Time continue to qualify as incentive stock
options after the Effective Time. At or prior to the Effective Time, FNB will
take all corporate action necessary to reserve for issuance sufficient shares of
FNB Common Stock for delivery upon exercise of Citizens Options assumed by it
and to cause such shares to be registered with the Securities and Exchange
Commission.

         All restrictions or limitations on transfer with respect to Citizens
Common Shares subject to Citizens Options or any other plan, program, or
arrangement of Citizens or of any subsidiary of Citizens, to the extent that
such restrictions or limitations will not have already lapsed, and except as
otherwise expressly provided in such plan, program, or arrangement, will remain
in full force and effect with respect to shares of FNB Common Stock into which
such restricted stock is converted pursuant to the Merger Agreement. See "--
Interests of Certain Persons in the Merger."



                                       13


   22



EFFECTIVE TIME OF THE MERGER

         The merger and the other transactions contemplated by the Merger
Agreement shall become effective on the date and at the time the Articles of
Merger shall have been accepted for filing by the Florida Department of State or
such other later date and time as is agreed to by the parties as specified in
the Articles of Merger (the "Effective Time"). Unless otherwise agreed by FNB
and Citizens, the parties have agreed to use their best efforts to cause the
Effective Time to occur on the date of closing and to use their reasonable best
efforts to cause the closing to take place on, but not prior to, the fifth
business day (as designated by FNB) following the last to occur of (i) the
effective date of the last required consent of any state or federal regulatory
authority having authority over the merger (including the expiration of all
applicable waiting periods following such consents or the delivery of
appropriate notices) or (ii) the date on which the shareholders of Citizens
approve the Merger Agreement. There can be no assurance as to whether or when
the merger will occur. See "The Merger -- Conditions Precedent to the Merger"
and "The Merger -- Bank Regulatory Matters."

EXCHANGE OF CERTIFICATES

         Before or as soon as practicable after the Effective Time, First
National Bank of Naples, a subsidiary of Southwest (the "Exchange Agent"), will
mail to each holder of record of Citizens Common Shares as of the Effective Time
a letter of transmittal and related forms (the "Letter of Transmittal") for use
in forwarding stock certificates previously representing Citizens Common Shares
for surrender and exchange for certificates representing FNB Common Stock. Risk
of loss and title to the certificates theretofore representing Citizens Common
Shares shall pass only upon proper delivery of such certificates to the Exchange
Agent.

         CITIZENS SHAREHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES UNTIL
THEY RECEIVE THE LETTER OF TRANSMITTAL FROM THE EXCHANGE AGENT.

         Upon surrender to the Exchange Agent of one or more certificates for
Citizens Common Shares, together with a properly completed Letter of
Transmittal, there will be issued and mailed to the holder thereof a certificate
or certificates representing the aggregate number of whole shares of FNB Common
Stock to which such holder is entitled pursuant to the Exchange Ratio, together
with all declared but unpaid dividends in respect of such shares, and, where
applicable, a check for the amount (without interest) representing any
fractional share. A certificate for shares of FNB Common Stock, or any check
representing cash in lieu of a fractional share or declared but unpaid
dividends, may be issued in a name other than the name in which the surrendered
certificate is registered only if (i) the certificate surrendered is properly
endorsed, accompanied by a guaranteed signature if required by the Letter of
Transmittal and otherwise in proper form for transfer, and (ii) the person
requesting the issuance of such certificate either pays to the Exchange Agent
any transfer or other taxes required by reason of the issuance of a certificate
for such shares in a name other than the registered holder of the certificate
surrendered or establishes to the satisfaction of the Exchange Agent that such
tax has been paid or is not applicable. The Exchange Agent will issue stock
certificates evidencing FNB Common Stock in exchange for lost, stolen,
mutilated, or destroyed certificates of Citizens Common Shares only upon receipt
of a lost stock affidavit and a bond indemnifying FNB against any claim arising
out of the allegedly lost, stolen, mutilated, or destroyed certificate. In no
event will the Exchange Agent, FNB, or Citizens be liable to any persons for any
FNB Common Stock or dividends thereon or cash delivered in good faith to a
public official pursuant to any applicable abandoned property, escheat, or
similar law.

         On and after the Effective Time and until surrender of certificates of
Citizens Common Shares to the Exchange Agent, each certificate that represented
outstanding Citizens Common Shares immediately prior to the Effective Time will
be deemed to evidence ownership of the number of whole shares of FNB Common
Stock into which such shares have been converted, and the holders thereof shall
be entitled to vote at any meeting of FNB shareholders. Beginning 30 days after
the Effective Time, no shareholder will, however, receive dividends or other
distributions on such FNB Common Stock until the certificates representing
Citizens Common Shares are surrendered. Upon surrender of Citizens Common Shares
certificates, Citizens shareholders will be paid any dividends or other
distributions on FNB Common Stock that are payable to holders as of any dividend
record date on or following the Effective Time. No interest will be payable with
respect to withheld dividends or other distributions. However, voting rights on
Citizens Common Shares continue for ninety (90) days after the Effective Time
regardless of whether certificates representing Citizens Common Shares have been
surrendered.

BACKGROUND OF AND REASONS FOR THE MERGER

         BACKGROUND OF THE MERGER.

         From time to time, Citizens has received informal inquiries from
financial institutions and individuals with respect to potential merger or
acquisition transactions involving Citizens. Although Citizens generally has
advised potential acquisition suitors that it was not interested in any such
transactions, Citizens has on occasion entered into confidentiality agreements
and exchanged information with such parties. However, none of these informal
inquires or preliminary discussions resulted in any formal or informal proposals
at such prices or on such terms as to alter Citizens' strategy to continue its
operations as an independent institution.

         FNB, which recently had undertaken a series of bank acquisitions in
southwest Florida, approached Citizens in mid-February 1998 about a potential
business combination. Although the inquiry was informal and indefinite,
officials of FNB held several follow-up telephone conferences with Citizens in
which they described FNB's Florida strategy and operations, explained the reason
for their interest in Citizens, and requested an informal meeting in March 1998
to explore further whether a business combination would be mutually beneficial.
During these conversations, Citizens identified, as a condition to even its
preliminary consideration of a transaction with FNB, a minimum price range that
FNB would have to be willing to consider as a starting point for any future
discussions. FNB indicated that it believed that an offer within that price
range may be possible, but that further analysis of Citizens would be necessary.
Based upon these discussions, Citizens agreed to meet with FNB to discuss the
matter further and, as a prelude to such meeting, the parties exchanged various
financial information.

         On March 19, 1998, David P. Stone, President of Citizens, and Citizens'
directors C. David Carley, Jr., and Alan C. Bomstein met with John Waters, Chief
Financial Officer of FNB, to discuss FNB's preliminary interest in a potential
business combination with Citizens, including various social issues, and FNB's
philosophy in maintaining the community banking nature of its Florida banking
operations. At this meeting FNB indicated that it was considering a transaction
in which the operations of Citizens would be combined with two other financial
institutions located in Pinellas County, Florida; one of which had recently
acquired and the other of which FNB was in the process of acquiring. FNB
believed that such a structure would achieve the values necessary to satisfy
Citizens' minimum price range requirements. Although no formal offer was made at
this meeting, FNB suggested that the parties enter into formal negotiations with
respect to a merger transaction pursuant to which Citizens shareholders would
receive FNB Common Stock in exchange for Citizens Common Shares.

         On March 20, 1998, the Citizens Board held a special meeting to review
FNB's preliminary indication of interest and the content of the informal
discussions held with FNB to date. The Citizens Board reviewed the history of
FNB, the performance of FNB common stock over the past five years, and FNB's
community banking philosophy for its Florida subsidiaries. In this regard, the
Citizens Board observed that FNB permits its Florida bank subsidiaries to
continue with their current community banking practices and local community
involvement after their acquisition by FNB. The Citizens Board noted the price
range informally discussed by the parties, and the liquidity and value that
would be created for its shareholders by receiving FNB Common Stock. Based upon
its analysis, the Citizens Board determined that it would be in the best
interests of Citizens shareholders to enter into negotiations with FNB. At this
meeting, the Citizens Board formally engaged Allan C. Ewing & Co., Inc.
("Ewing"), a firm specializing in financial institutions, to serve as Citizens'
financial advisor to assist in negotiations with FNB and to advise on the
fairness of any such offer from a financial point of view to the Citizens
shareholders. Ewing was selected based on its knowledge of financial
institutions, its expertise as a financial advisor in mergers and acquisitions
of financial institutions, and its familiarity with Citizens. The Citizens Board
also established a special committee ("Special Committee") consisting of Messrs.
Stone, Carley, and Bomstein to negotiate the terms of any proposed transaction.
On March 27, 1998, Citizens engaged legal counsel to assist it in the
negotiations.

         On April 2, 1998, the Special Committee, Ewing, and Citizens' counsel
met with representatives of FNB and its legal counsel to negotiate the terms and
conditions of a proposed business combination. During these negotiations, FNB
made an offer to acquire Citizens in a transaction in which Citizens
shareholders would receive 1.515 shares of FNB Common Stock in exchange for each
Citizens Common Share.



                                       15


   24



         On April 3, 1998, the Citizens Board held a special meeting to review
the material terms of the FNB offer. Counsel was present at this meeting and
advised the Citizens Board of its duties and obligations in analyzing and
considering the offer. At this meeting Ewing presented a comparison of Citizens'
historical financial results with those of other banks in Florida and the
financial terms of recent Florida bank acquisitions. In addition, Ewing provided
an analysis of the recent stock performance of FNB Common Stock and noted the
lack of liquidity for the Citizens Common Shares. The presentation also included
an analysis of FNB's operating performance and dividend payouts by FNB. Ewing
compared the financial terms of the offer to comparable transactions of similar
institutions and orally expressed its opinion to the Citizens Board that the
terms of the offer were fair, from a financial point of view, to the
shareholders of Citizens. After further discussion, the Citizens Board
unanimously agreed to accept the offer subject to the negotiation of a
definitive Merger Agreement. The Citizens Board then authorized the Special
Committee to proceed with the negotiation of a definitive Merger Agreement.

         From April 3, 1998 through April 6, 1998, the Special Committee,
representatives of FNB, and their respective counsel, negotiated the terms of a
definitive Merger Agreement and on April 6, 1998, the Citizens Board held a
special meeting to review and consider the terms and conditions of the
agreement. Copies of the definitive Merger Agreement were distributed and the
Citizens Board reviewed in detail with counsel the material terms of the Merger
Agreement and the merger, including the latest changes in the documents
resulting from the negotiations with FNB. After discussion and deliberation, the
Citizens Board approved the Merger Agreement and the related merger, and
immediately thereafter, at the instruction of the Citizens Board, Mr. Stone
executed the Merger Agreement.

         By letter dated April 20, 1998, in accordance with the terms of the
Merger Agreement, FNB advised Citizens of several items that it had discovered
during the course of its due diligence investigation. Although Citizens did not
necessarily agree with the conclusions of FNB with respect thereto, the parties
agreed to take certain actions to resolve FNB's concerns, including an agreement
to revise the Merger Agreement to lower the FNB Average Price at which Citizens
could terminate the Merger Agreement from $34.125 to $33.6875 per share.

         On June 29, 1998, the parties further discussed the terms of the Merger
Agreement which provided Citizens with the right to terminate the transaction in
the event that the FNB Average Price is less than $33.6875 per share. Because
the FNB Common Stock had from time to time closed at a price lower than $33.6875
per share during the period between June 15, 1998 and June 29, 1998, the parties
determined that it would be prudent to discuss a possible revision of the Merger
Agreement. After discussions held throughout the day, the parties agreed to
revise the terms of the Merger Agreement to provide that (i) the Exchange Ratio
would be determined by reference to schedule attached to the Merger Agreement
(see Appendix A) if the FNB Average Price was between $32.50 and $36.75 per
share, (ii) if the FNB Average Price was $32.50 per share or less, the Exchange
Ratio would adjust to provide for a number of shares of FNB common stock equal
in value to $56.16 per Citizens Common Share, (iii) if the FNB Average Price was
$36.75 per share or higher, the Exchange Ratio would adjust to provide for a
number of shares of FNB common stock equal in value to $62.07 per Citizens
common share, (iv) Citizens' right to terminate the Merger Agreement if the FNB
Average Price was less than $33.6875 be eliminated, and (v) FNB may terminate
the Merger Agreement if the FNB Average Price is below $30.00. On July 7, 1998,
the Citizens Board approved the revisions and the parties entered into the First
Amendment to the Merger Agreement reflecting their agreement.

         CITIZENS' REASONS FOR THE MERGER.

         In evaluating and determining to approve the Merger Agreement, the
Citizens Board, with the assistance of Ewing and outside legal counsel,
considered a variety of factors and based its opinion as to the fairness of the
transactions contemplated by the Merger Agreement primarily on the following
factors:

         (i)  The financial terms of the Merger, including the value of the
consideration offered, the premium to book value paid, the prices paid in
comparable transactions, relative earnings per share, and the relative
shareholders' equity of FNB and Citizens. The Citizens Board also considered the
current lack of liquidity for the Citizens Common Shares and the active trading
market for the FNB Common Stock.

         (ii) The future prospects of Citizens and possible alternatives to the
proposed merger of Citizens with FNB, including the prospects of continuing as
an independent institution. The Citizens Board considered the timing of the
offer


                                       16


   25



and the prospects for receiving a better financial offer from another
institution having the same commitment to providing community banking services
to is customers following a merger.

         (iii)  The opinion of Ewing that the terms of the merger as provided in
the Merger Agreement were fair, from a financial point of view, to Citizens
shareholders. The opinion of Ewing is set forth in Appendix C to this Proxy
Statement-Prospectus.

         (iv)   Information with respect to the financial condition, results of
operations, business and prospects of Citizens and the current industry,
economic, and market conditions, as well as the risks associated with achieving
those prospects.

         (v)    The non-financial terms and structure of the Merger Agreement 
and the proposed merger, in particular, the fact that the merger is intended to
qualify as a tax-free reorganization to Citizens shareholders.

         (vi)   The business and financial condition and earnings prospects of
FNB, the potential growth of FNB Common Stock, and the competence, experience,
and integrity of FNB and its management. In this regard, Citizens also
considered the increasing commitment of FNB to the Florida banking market and
the prospects for additional growth in the Florida market, especially in
Citizens' primary market area.

         (vii)  The social and economic effects of the merger on Citizens and 
its employees, depositors, loan and other customers, creditors, and other
constituencies of the communities in which Citizens is located. The Citizens
Board considered the terms of the employee benefits to be received, the proposed
structure and operation of the resultant financial institution as a community
bank following the merger, and the commitment to customer quality and service
that FNB would provide to Citizens' customers and depositors.

         (viii) The likelihood of the proposed merger being approved by
appropriate regulatory authorities.

         Each of the above factors support, directly or indirectly, the
determination of the Citizens Board as to the fairness of the Merger Agreement
and the related merger. The Citizens Board did not quantify or attempt to assign
relative weights to the specific factors considered in reaching its
determination; however, the Citizens Board placed special emphasis on the
consideration payable in the proposed merger and the receipt of a favorable
fairness opinion from its financial advisor. See "-- Opinion of Citizens'
Financial Advisor."

         FNB'S REASONS FOR THE MERGER. The FNB Board recognized that the
proposed merger with Citizens provides an opportunity to continue to employ
FNB's growing capital on the west coast of Florida, one of the fastest growing
markets in the United States. This is in contrast to the more mature market
areas of Pennsylvania, eastern Ohio, and southwestern New York where FNB had
traditionally operated, prior to its acquisitions of Southwest, West Coast
Bancorp, Inc., Indian Rocks State Bank, Mercantile Bank of Southwest Florida,
West Coast Bank, and Seminole Bank. FNB's management believes that the proposed
merger complements FNB's acquisitions on the west coast of Florida and will
provide FNB with a greater level of market competitiveness in Pinellas County.
Following the merger, Citizens Bank & Trust will be merged into First National
Bank of Florida and will be able to draw upon the resources and competencies of
FNB's other Florida affiliates to provide a broader range of services and
product delivery channels.

OPINION OF CITIZENS' FINANCIAL ADVISOR

         The Citizens Board retained Ewing in late March 1998 to advise Citizens
in its negotiations with FNB and for the purpose of rendering its opinion (the
"Opinion") to the shareholders of Citizens as to the fairness, from a financial
point of view, of the terms of any proposed merger transaction with FNB
resulting from the negotiations. A representative of Ewing attended the meeting
of the Citizens Board held on April 3, 1998, and at such meeting Ewing delivered
its oral Opinion that, as of the date of the meeting and based upon and subject
to certain assumptions and market conditions, the offer to the holders of
Citizens Common Shares as proposed by FNB was fair, from a financial point of
view. Ewing's written Opinion was issued on May 15, 1998. Ewing updated its
opinion on July 6, 1998 and



                                       17


   26



reconfirmed that the transaction was fair from a financial point of view to the
shareholders of Citizens after reviewing and analyzing the terms of the First
Amendment which was entered into by the parties on July 7, 1998.

         Ewing's Opinion is directed to the Citizens Board and does not
constitute a recommendation to any Citizens shareholder as to how such
shareholder should vote on the merger. Ewing has not been requested to opine as
to and the Opinion does not in any manner address the underlying business
decision by the Citizens Board to enter into the Merger Agreement and the
related merger. No limitations were imposed on the scope of Ewing's analysis or
the procedures followed by Ewing in rendering its Opinion.

         In issuing its Opinion, Ewing assumed and relied upon the accuracy and
completeness of the financial and other information used by it in arriving at
its Opinion as provided by Citizens. Ewing made no independent verification of
the supplied information, nor did Ewing conduct a physical inspection of the
properties and facilities of Citizens, nor did Ewing make or obtain any
evaluation or appraisal of the assets or liabilities of Citizens, nor did Ewing
review any credit or loan files from Citizens' loan portfolio. The Opinion is
based upon market and economic conditions as they existed on the date of the
Opinion. Events occurring after the date of issuance of the Opinion including
but not limited to, changes in the market price of securities, the results of
operations, or material changes in the value of the assets or liabilities of
Citizens could affect the assumptions used and the conclusions of the Opinion.

         The full text of Ewing's Opinion is attached as Appendix C to this
Proxy Statement-Prospectus and is incorporated herein by reference. The
description of the Opinion set forth herein is qualified in its entirety by
reference to Appendix C. Citizens shareholders are urged to read the Opinion in
its entirety.

         In arriving at its Opinion, Ewing: (i) reviewed the audited financial
statements prepared by Hacker, Johnson, Cohen & Grieb, PA of Tampa, Florida, for
the fiscal years ended December 31, 1997, December 31, 1996 and December 31,
1995; (ii) reviewed the Call Reports of Citizens Bank & Trust filed with the
regulators reflecting operations of Citizens Bank & Trust for the periods ended
March 31, 1998, December 31, 1997, December 31, 1996 and December 31, 1995;
(iii) reviewed the Merger Agreement dated April 6, 1998; (iv) reviewed the
budget for the Bank for the year 1998; (v) reviewed the four-year plan for the
Bank (1997-2000); (vi) reviewed other financial information concerning Citizens;
(vii) compared the terms of the Merger Agreement with FNB with the terms offered
shareholders of comparable institutions in Florida in recent transactions;
(viii) reviewed the public information concerning the operations of FNB; (ix)
examined Citizens' market share in the Pinellas County market including other
competitive banking institutions active in Citizens' market area; (x) compared
Citizens' financial performance with other comparable banking institutions
operating in Florida; (xi) reviewed the financial condition of FNB and the
impact of the proposed transaction on the market price of the shares of FNB; and
(xii) reviewed the price performance and trading activity in the shares of FNB
over the past six months. Ewing had discussions with the management of Citizens
concerning its historical operations and future prospects and the decision of
the Citizens Board to negotiate with FNB.

         The following paragraphs summarize the most pertinent portions of the
financial and comparative analyses prepared by Ewing in arriving at its Opinion.
The following summary does not purport to be a complete description of the
analyses performed or the matters considered by Ewing in arriving at its
Opinion.

         The preparation of a fairness opinion involves various determinations
as to the most appropriate and relevant methods of financial analysis and the
application of those methods to the particular circumstances. Therefore, such an
opinion is not readily susceptible to summary description. Furthermore, in
arriving at its Opinion, Ewing did not attribute any particular weight to any
one factor considered by it, but rather made qualitative judgments as to the
significance and relevance of each analysis and factor. Ewing believes that its
analysis must be considered as a whole and that considering any portions of such
analysis and of the factors considered, without considering all analyses and
factors, could create a misleading or incomplete view of the process underlying
its Opinion. In its analysis, Ewing made numerous assumptions with respect to
industry performance, general business and economic conditions and other
matters, many of which are beyond Citizens' control. Any estimates contained in
these analyses are not necessarily indicative of actual values or predictive of
future results or values, which may be significantly more or less favorable than
as set forth therein. Analyses relating to the value of businesses do not
purport to be appraisals or to reflect the prices at which businesses actually
may be sold. In addition, as described above, Ewing's Opinion, along with its
presentations to the Citizens Board, was just one of many factors taken into
consideration by the Citizens Board.

   27
         TRADING HISTORY OF CITIZENS COMMON SHARES. In view of the fact that the
Citizens Common Shares are closely held, Ewing found that there was no
meaningful trading market in the Citizens Common Shares.

         SELECTION OF VALUATION METHOD. In valuing financial institutions, Ewing
believes that there are several methods available to determine if a prospective
transaction is fair, from a financial point of view, to the shareholders of the
institution to be acquired. These methods include: (i) Comparison Method: A
comparison of the purchase price of the transaction with prices paid for similar
banks based on ratios commonly used in the industry, including price/book,
price/earnings, and price/deposits; (ii) Control Premium Method: This method
only applies to selling companies where there is a public market for their
shares, and, as there is not an active market for the shares of Citizens, this
method does not apply; (iii) Net Asset or Liquidating Value Method: This method
does not apply to healthy banks and is only used in periods of severely
depressed markets; (iv) Discounted Cash Flow Method: This method is often used
in valuing community banks for the primary purpose of validating valuations
determined by the Comparison Method or other methods. This method is based on
the ability to forecast earnings and dividends for a period of years with an
estimate of the value of a projected sale at the end of the period. The present
value of these projected cash flows representing the value of Citizens is
determined using an array of discount rates reflecting the credibility of the
projections. Earnings for small banks tend to be volatile for many reasons
including normal banking activities such as the addition of a new branch, a new
marketing program, the hiring of new banking officers, all of which can have an
adverse affect on current earnings. For these reasons, earnings projections for
smaller banks tend to have less reliability which, in Ewing's opinion, reduces
the value of the Discounted Cash Flow method when used as the primary method for
valuing community banks. Ewing believes that the Comparison Method provides the
soundest choice for determining the fairness of this transaction, but that the
Discounted Cash Flow Method is useful in confirming the valuation determined by
the Comparison Method.

         ANALYSIS OF COMPARABLE COMPANIES. Using publicly available information
including information prepared by SNL Securities, Ewing compared the financial
performance of Citizens with two relevant groups of banks.

         In the first group, Ewing compared five performance indicators of
Citizens with the average performance of 221 independent Florida community
banks. The performance indicators utilized by Ewing for this comparison included
the return on average assets for 1997 which was .98% for Citizens vs. 1.02% for
the 221 banks; the return on average equity for 1997 which was 9.34% for
Citizens vs. 11.00% for the 221 banks; the equity/assets ratio which for
Citizens as of December 31, 1997 was 10.12% vs. 9.25% for the 221 Florida banks;
the ratio of non-performing assets/assets which for Citizens was .08% vs. .36%
for the 221 banks; and the ratio of operating expenses/operating revenues which
was 73.10% for Citizens vs. 70.20% for the 221 Florida banks.

         In the second group, Ewing compared four performance indicators of
Citizens with the average performance indicators of 10 selected comparable banks
which were merged with larger companies in 1997 and 1998. The performance
indicators utilized by Ewing for this comparison included the return on average
assets which was .98% for Citizens vs. 1.26% for the 10 banks; the return on
average equity which was 9.34% for Citizens vs. 14.30% for the 10 banks; the
ratio of non-performing assets/assets which was .08% for Citizens vs. .17% for
the 10 banks; and the ratio of equity/assets which was 10.12% for Citizens vs.
8.89% for the 10 banks.

         ANALYSIS OF COMPARABLE TRANSACTIONS. Using publicly available
information, Ewing reviewed certain terms and financial characteristics of
selected transactions involving the acquisition of healthy banks by commercial
bank holding companies in 1997 and 1998. In view of Citizens' high asset quality
and favorable operating comparisons with the two groups of banks discussed in
the Comparable Company Analysis, Ewing selected transactions for comparison
purposes involving similarly performing banks in Florida. Ewing initially
selected transactions that occurred in a period of similar economic activity,
and determined that the period commencing January 1, 1997 through March 31, 1998
was the optimum period for the selection of comparable transactions. Because of
the large amount of consolidation activity in the Florida banking market, Ewing
determined that there were a sufficient number of transactions involving
comparable banks in Florida to provide a sufficiently large universe for
comparison purposes. There were 35 transactions that occurred during this period
involving Florida banks, and Ewing applied the following criteria in selecting
the most comparable transactions: Ewing eliminated all transactions involving
selling banks with assets less than $75 million and in excess of $175 million.
Ewing eliminated all transactions in which the operations of the acquired bank
were unprofitable in the year of acquisition. Ewing eliminated all transactions
involving selling banks with non-performing assets in excess of 1.0% of assets.
Ewing eliminated all transactions where the selling bank had a return on average
assets 




                                       19









   28
("ROAA") in the year of acquisition of less than 1.0% and/or a return on average
equity ("ROAE") of less than 8.0%. T he following ten transactions met the above
criteria (identified by acquiree/acquiror): CNB Holding/Colonial BancGroup,
Montgomery, Alabama; Seminole Bank/FNB Corporation, Hermitage, Pennsylvania;
Central Bank/BankUnited Financial, Coral Gables, Florida; West Coast Bank/FNB
Corporation, Hermitage, Pennsylvania; Dadeland Bancshares/Colonial BancGroup,
Montgomery, Alabama; Bank of Winter Park/Huntington Bancshares, Columbus, Ohio;
Florida Gulfcoast/Provident Bancorp, Cincinnati, Ohio; Indian Rocks State
Bank/FNB Corporation, Hermitage, Pennsylvania; Great Southern Bancorp/Colonial
BancGroup, Montgomery, Alabama; Port St. Lucie National Bank/Seacoast Banking
Corporation, Stuart, Florida.

         Ewing utilized the following three ratios that are generally utilized
in the industry for comparing the relative prices paid in transactions involving
banks: price/book value which was 3.29x for Citizens vs. 2.68x for the ten
banks; price/earnings which was 37.00x for Citizens vs. 20.25x for the ten
banks; price as a percentage of deposits which was 38.85% for Citizens vs.
27.90% for the ten banks.

         Because the reasons for and circumstances surrounding each of the
transactions analyzed were diverse and because of the inherent differences
between the operations of Citizens and the selected companies, Ewing believes
that a strict reliance on the quantitative comparable transaction analysis is
not meaningful without further qualitative considerations. Ewing believes that
the proper use of a comparable transaction analysis would involve qualitative
judgments concerning differences between the characteristics of these
transactions and the Citizens merger which may have affected the acquisition
value of the acquired companies and Citizens. The qualitative factors considered
by Ewing in connection with its Opinion included Ewing's views as to the number
of potential buyers in each of these transactions and the ability of the
acquirors to implement cost savings and business synergies.

         DISCOUNTED CASH FLOW ANALYSIS. Ewing projected the cash flows of
Citizens based on Citizens' business plan for the three-year period ended
December 31, 2000, assuming that Citizens would remain as an independent bank.
For purposes of this analysis, Ewing assumed that all future earnings would be
retained and that Citizens would enter into a merger contract as of December 31,
2000, based on the average price/earnings, price/book, and price/deposits ratios
that exist currently. These ratios are 2.68x book value, 20.25x earnings, and
27.90% of deposits. The projected sales price of Citizens was determined from
these ratios on a weighted basis by giving a 45% weight to price/earnings, a 45%
of weight to price/book, and a 10% weight to price/deposits. This projected
value for Citizens was then discounted to present value utilizing an array of
discount rates of 14%-16%. These rates were selected based on Ewing's estimate
of the rate that investors would require in making an investment based on the
projected sale of Citizens. Ewing determined that the appropriate discount rate
was approximately 15.00%, and this rate was achieved by layering appropriate
risk rates which took into consideration the basic riskless rate of Treasury
Notes for the indicated time period (three years), the general risks of equity
investment, the historical cyclicality of bank earnings in general, and the
volatility of small bank earnings.

         Based upon this analysis, Ewing determined that the present value of
the projected cash flows was less than the indicated values presented by the
Merger Agreement to Citizens shareholders.

         ANALYSIS OF FNB SHARES. Ewing performed an analysis as to the
profitability, quality and liquidity of the shares of FNB including a comparison
of FNB's operating performance with the average of seven other regional bank
holding companies ("BHCs") including AmSouth, Colonial, Compass, Regions,
SouthTrust, Union Planters, and Huntington. Ewing observed that FNB produced an
ROAA in 1997 of 1.31% vs. an average of 1.21% by the seven BHCs; an ROAE of
15.41% vs. 15.77% for the seven BHCs; NPAs/Assets of .54% vs. 4.5% for the seven
BHCs; and FNB had a stronger equity/assets ratio of 8.70% vs. an average of
7.76% for the seven BHCs.

         Ewing reviewed the historical trading prices and volumes for FNB over
the past six months and compared the price performance of FNB shares during this
period to other regional banks. Ewing found the performance of FNB to be
comparable to those of its peers and that FNB shares offer moderate liquidity to
its shareholders.

         Ewing observed that as of April 3, 1998, FNB shares were trading at
approximately $39.00 per share which represented a multiple of book value of
2.55x and a multiple of 1997 earnings of 24.38x.

   29



         THE FINANCIAL EFFECTS OF THE FIRST AMENDMENT ON THE TERMS OF THE
PROPOSED TRANSACTION. On June 29, 1998 the parties agreed in principle to the
terms of a First Amendment to the Merger Agreement whereby FNB agreed to issue
additional FNB shares to Citizens shareholders subject to the level of the
market price of FNB shares for a specified period prior to closing. Ewing
analyzed the financial effect of the terms of the First Amendment on the
original terms of the Merger Agreement and observed that the new terms will
result in a higher price being received by the Citizens shareholders. Ewing also
observed that FNB acquired the right to terminate the Merger Agreement if the
market price for FNB shares falls below $30.00.

         Ewing determined that the terms of the First Amendment were favorable
to the shareholders of Citizens.

         COMPENSATION OF ALLEN C. EWING & CO. Ewing served as financial advisor
to Citizens in addition to rendering its Opinion. As compensation for its
services, Ewing will earn a fee of approximately $25,000.

CONDITIONS PRECEDENT TO THE MERGER

         The merger will occur only if the Merger Agreement is approved by the
requisite vote of the shareholders of Citizens. Consummation of the merger is
subject to the satisfaction of certain other conditions, unless waived, to the
extent legally permitted. Such conditions include (i) the receipt of all
required regulatory and governmental consents, approvals, authorizations,
clearances, exemptions, waivers, or similar affirmations (and the expiration of
all applicable waiting periods following the receipt of such items or the
delivery of appropriate notices), provided that such approvals shall not have
imposed any condition or restriction that, in the reasonable judgment of the
Board of Directors of either party, would so materially adversely impact the
economic or business benefits of the transactions contemplated by the Merger
Agreement that, had such condition or requirement been known, such party would
not, in its reasonable judgment, have entered into the Merger Agreement; (ii)
the receipt, with certain exceptions, of all consents required for consummation
of the merger and the preventing of any default under any contract of such party
which, if not obtained or made, is reasonably likely to have, individually or in
the aggregate, a material adverse effect on such party; (iii) the absence of any
action by a court or governmental or regulatory authority that restricts,
prohibits or makes illegal the transactions contemplated by the Merger
Agreement; (iv) the effectiveness of the Registration Statement under the
Securities Act of 1933, as amended (the "Securities Act") and the receipt of all
necessary approvals under state securities laws, the Securities Act or the
Securities and Exchange Act of 1934, as amended (the "Exchange Act") relating to
the issuance or trading of the shares of FNB Common Stock issuable pursuant to
the merger; (v) the receipt of a letter dated as of the Effective Time from
Ernst & Young LLP to the effect that the merger qualifies to be accounted for as
a pooling-of-interests under GAAP; and (vi) the receipt of the tax opinion
referred to in "-- Certain Federal Income Tax Consequences."

         In addition, unless waived, each party's obligation to effect the
merger is subject to the accuracy of the other party's representations and
warranties at the Effective Time and the performance by the other party of its
obligations under the Merger Agreement and the receipt of certain closing
certificates from the other party. The obligation of FNB to effect the merger
also is subject to the receipt of agreements from affiliates of Citizens
restricting their ability to sell or otherwise transfer their Citizens Common
Shares prior to consummation of the merger or their shares of FNB Common Stock
received upon consummation of the merger, to the extent necessary to assure, in
the reasonable judgment of FNB, that the transactions contemplated by the Merger
Agreement will qualify for pooling-of-interests accounting treatment. FNB also
may terminate the Merger Agreement if, after the latter of the effective date of
the last required consent of any regulatory authority or the date Citizens
shareholders approve the merger (the "Determination Date"), the FNB Average
Price (i.e., the average of the high bid and low asked prices of the FNB Common
Stock in the over-the-counter market for the ten consecutive trading days prior
to the fifth business day prior to the Determination Date) is less than $30.00.
The obligation of Citizens to effect the merger is further subject to (i)
Citizens' receipt from Ewing of a letter, dated not more than five business days
prior to the date of this Proxy Statement-Prospectus, stating that in the
opinion of Ewing, the consideration to be paid is fair, from a financial point
of view, to the holders of Citizens Common Shares; (ii) FNB having delivered the
consideration to be paid to holders of the Citizens Common Shares; and (iii)
Citizens' receipt of a written opinion of Smith, Gambrell & Russell, LLP, dated
as of the Effective Time, with respect to such matters and in such form as shall
be agreed upon between such firm and Citizens. No assurances can be provided as
to when or if all of the conditions precedent to the merger can or will be
satisfied or waived by the party permitted to do so. 



                                       21
   30
         Either Citizens or FNB may waive certain of the conditions imposed with
respect to its or their respective obligations to consummate the merger, except
for requirements that the merger be approved by Citizens shareholders and that
all required regulatory approvals be received.

CONDUCT OF BUSINESS PRIOR TO THE MERGER

         Under the terms of the Merger Agreement, Citizens has agreed, except as
otherwise contemplated by the Merger Agreement, to (i) operate its business only
in the usual, regular and ordinary course, (ii) use its reasonable efforts to
preserve intact its business organization and assets and maintain its rights and
franchises, (iii) use its reasonable efforts to maintain its current employee
relationships, and (iv) take no action which would materially adversely affect
the ability of any party to obtain any consent or approvals required for the
transactions contemplated by the Merger Agreement without imposition of a
condition or restriction which in the reasonable judgement of the Board of
Directors of either party would so materially adversely impact the economic or
business benefits of the transactions contemplated by the Merger Agreement that,
had such condition or requirement been known, such party would not, in its
reasonable judgement, have entered into the Merger Agreement.

         In addition, Citizens has agreed that it will not, without the prior
written consent of FNB:

                  (a) amend the Citizens Charter, the Citizens bylaws ("Citizens
Bylaws"), or other governing instruments of Citizens or any Citizens subsidiary;

                  (b) except for loans secured by a first mortgage on single
family owner-occupied real estate, make any unsecured loan or other extension of
credit in excess of $100,000, or make any fully secured loan to any person
(except those who have received a commitment for a loan or extension of credit
prior to the date of the Merger Agreement) in excess of $250,000 (in either case
FNB shall object thereto within two business days, and the failure to provide a
written objection within two business days shall be deemed as the approval of
FNB to make such loan or extend such credit);

                  (c) incur any additional debt obligation or other obligation
for borrowed money (other than indebtedness of Citizens or any of its
subsidiaries to Citizens or any of its subsidiaries) in excess of an aggregate
of $100,000 except in the ordinary course of the business consistent with past
practices, or impose, or suffer the imposition, with certain exceptions, of a
lien on any asset of Citizens or its subsidiaries (other than in connection with
deposits, repurchase agreements, bankers acceptances, treasury tax and loan
accounts established in the ordinary course of business, the satisfaction of
legal requirements in the exercise of trust powers, and already existing liens);

                  (d) repurchase, redeem, or otherwise acquire or exchange
(other than exchanges in the ordinary course under employee benefit plans),
directly or indirectly, any shares, or any securities convertible into any
shares, of the capital stock of Citizens or any subsidiary, or declare or pay
any dividend or make any other distribution in respect of its capital stock
(except for acquisition of Citizens Common Shares by any Citizens subsidiary in
a fiduciary or trust capacity in the ordinary course of business);

                  (e) except for the Merger Agreement, or pursuant to the Stock
Option Agreement (attached as Appendix B, the "Stock Option Agreement") or the
exercise of the Citizens Options, issue, sell, pledge, encumber, authorize the

its fiduciary capacity, or (iii) the creation of new wholly owned subsidiaries

or pursuant to contracts or agreements in force at the date of the Merger
Agreement; or

                  (p) agree to, or make any commitment to, take any of the
actions prohibited by the above paragraphs.

         The Merger Agreement also provides that, except for the transactions
contemplated thereby, neither Citizens nor its affiliates or representatives
shall, directly or indirectly, solicit any tender offer or exchange offer or any
proposal for a

                                       23


   32




merger, consolidation, acquisition of all of the stock or assets of, or other
business combination involving Citizens or any of its subsidiaries or any
proposal or offer to acquire in any manner a substantial equity interest in, or
a substantial portion of the assets of, Citizens or any of its subsidiaries
("Acquisition Proposal"). Additionally, except to the extent necessary to comply
with the fiduciary duties of the Citizens Board, as advised by counsel, neither
Citizens nor its affiliates or representatives will provide any non-public
information that it is not legally obligated to furnish or negotiate with
respect to any Acquisition Proposal, although Citizens may communicate
information about such Acquisition Proposal to its shareholders if and to the
extent that it is required to do so in order to comply with its legal
obligations, as advised by counsel.

         In the Merger Agreement, FNB has agreed (i) to conduct its business and
the business of its subsidiaries in a manner designed, in its reasonable
judgment, to enhance the long-term value of the FNB Common Stock and its
business prospects and (ii) to take no action which would materially adversely
affect the ability of any party to obtain any consent or approvals required by
the Merger Agreement or to perform its covenants and agreements under the Merger
Agreement; provided that FNB or any of its subsidiaries may discontinue or
dispose of any of its assets or business if FNB determines that such action is
desirable in the conduct of its business. FNB further agreed that it will not,
without the prior written consent of the Chief Executive Officer of Citizens,
which consent shall not be unreasonably withheld, amend the FNB Charter ("FNB
Charter") or the FNB Bylaws ("FNB Bylaws") in any manner adverse to the holders
of Citizens Common Shares.

MODIFICATION, WAIVER, AND TERMINATION

         The Merger Agreement provides that it may be amended by a subsequent
writing signed by each party upon the approval of each of their respective Board
of Directors. However, the provision relating to the consideration to be
received by the holders of Citizens Common Shares may not be amended after the
Special Meeting in a manner to reduce or modify in any material respect the
consideration to be received by the holders of the Citizens Common Shares
without the further approval of the holders of the issued and outstanding shares
of Citizens Common Shares entitled to vote thereon.

         The Merger Agreement provides that each party may (i) waive any default
in the performance of any term of the Merger Agreement by the other party, (ii)
waive or extend the time for compliance of fulfillment by the other party of any
of its obligations under the Merger Agreement and (iii) waive any of the
conditions precedent to its obligations to consummate the merger to the extent
legally permitted. Neither of the parties intends, however, to waive any
conditions of the merger if such waiver would, in the judgment of the waiving
party, have a material adverse effect on its shareholders.

         The Merger Agreement may be terminated by mutual agreement of the FNB
Board and the Citizens Board. The Merger Agreement may also be terminated by
either the FNB Board or the Citizens Board (i) in the event of inaccuracies of
any representation or warranty of the other party contained in the Merger
Agreement which cannot be or has not been cured within 30 days of written notice
of such inaccuracies and which inaccuracy would provide the terminating party
the ability to refuse to consummate the merger under the applicable standard set
forth in the Merger Agreement; provided that such party is not then in breach of
any representation or warranty contained in the Merger Agreement or in material
breach of any covenant or other agreement contained in the Merger Agreement;
(ii) in the event of a material breach of any covenant or agreement in the
Merger Agreement by the other party that cannot or has not been cured within 30
days of written notice of such breach; (iii) if the required approval of the
Citizens shareholders or any applicable regulatory or governmental authority is
not obtained; or (iv) if the merger is not consummated by December 31, 1998;
provided that the failure to consummate the merger by such date is not caused by
any breach of the Merger Agreement by the terminating party.

         The Merger Agreement may be terminated by FNB in the event that
dissenters' rights claimed pursuant to the applicable provisions of the Florida
Business Corporation Act ("FBCA") aggregate more than 10% of the issued and
outstanding Citizens Common Shares, or if at any time during the period
commencing on the Determination Date and ending at the close of business on the
day before the Effective Time, if the FNB Average Price shall be less than
$30.00 per share. In addition, the Merger Agreement may be terminated by
Citizens if (i) at any time prior to the Effective Time, the fairness opinion of
Ewing is withdrawn; or (ii) prior to the Effective Time, a corporation,
partnership, person or other 



                                       24
   33

entity or group shall have made a bona fide Acquisition Proposal that the
Citizens Board determines in its good faith judgment and in the exercise of its
fiduciary duties, with respect to legal matters on the written opinion of legal
counsel and as to financial matters on the written opinion of an investment
banking firm of national reputation, is more favorable to the Citizens
shareholders and that the failure to terminate the Merger Agreement and accept
such alternative Acquisition Proposal would be inconsistent with the proper
exercise of such fiduciary duties (each a "Termination Event"). There can be no
assurance that the Citizens Board would exercise its right to terminate the
Merger Agreement if a Termination Event exists.

         It is not possible to know whether a Termination Event will occur until
after the Determination Date or the Effective Time. The Citizens Board has made
no decision as to whether it would exercise its termination right in such
situation. The Citizens Board would, consistent with its fiduciary duties, take
into account all relevant facts and circumstances that exist at such time, and
would consult with its financial advisers and legal counsel.

         Approval of the Merger Agreement by the shareholders of Citizens at the
Special Meeting will confer on the Citizens Board the power, consistent with its
fiduciary duties, to elect to consummate the merger in the event of a
Termination Event without any further action by, or resolicitation of, the
shareholders of Citizens.

STANDSTILL PROVISIONS

         In the event that the Merger Agreement and the related merger are not
consummated, FNB will be generally prohibited from purchasing shares of Citizens
or soliciting proxies for a period of three (3) years from, in some cases, April
6, 1998 and, if the Merger Agreement is terminated as permitted in Section 10.1
thereof, three (3) years from the date of such termination. This restriction
does not prevent FNB from indirectly acquiring any equity securities of Citizens
by acquiring a financial institution that owns equity securities of Citizens.

EXPENSES

         In the Merger Agreement, each of the parties has agreed to pay its own
expenses and one-half of the printing costs of this Proxy Statement-Prospectus
and related materials; provided, however, that in the event of any termination
of the Merger Agreement following the occurrence of an Initial Triggering Event
(as defined in the Stock Option Agreement), FNB shall be entitled to a cash
payment from Citizens in an amount equal to $250,000 upon the occurrence of any
Subsequent Triggering Event (as defined in the Stock Option Agreement) within 12
months following the date of such termination (or such longer period as shall
exist under the Stock Option Agreement until the occurrence of an Exercise
Termination Date (as defined in the Stock Option Agreement)). In the event the
Merger Agreement is terminated as a result of FNB's failure to satisfy any of
its representations, warranties or covenants set forth therein, FNB shall
reimburse Citizens for its reasonable out-of-pocket expenses relating to the
merger in an amount not to exceed $150,000.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         Smith, Gambrell & Russell, LLP has delivered to FNB and Citizens its
opinion that, based upon certain customary assumptions and representations,
under federal law as currently in effect, (a) the proposed merger will
constitute a reorganization within the meaning of Section 368(a) of the Code;
(b) no gain or loss will be recognized by the shareholders of Citizens on the
exchange of their Citizens Common Shares for FNB Common Stock pursuant to the
terms of the merger to the extent of such exchange; (c) the federal income tax
basis of the FNB Common Stock for which Citizens Common Shares are exchanged
pursuant to the merger will be the same as the basis of such Citizens Common
Shares exchanged therefor (including basis allocable to any fractional interest
in any share of FNB Common Stock); (d) the holding period of FNB Common Stock
for which Citizens Common Shares are exchanged will include the period that such
shares of Citizens Common Shares were held by the holder, provided that such
shares were capital assets of the holder; and (e) the receipt of cash in lieu of
fractional shares will be treated as if the fractional shares were distributed
as part of the exchange and then redeemed by FNB, and gain or loss will be
recognized in an amount equal to the difference between the cash received and
the basis of the fractional share of FNB Common Stock surrendered, which gain or
loss will be capital gain or loss if the Citizens Common Shares was a capital
asset in the hands of the shareholder.

         THE FOREGOING IS A SUMMARY OF THE ANTICIPATED FEDERAL INCOME TAX
CONSEQUENCES OF THE PROPOSED MERGER UNDER THE CODE AND IS FOR GENERAL
INFORMATION ONLY. IT DOES NOT INCLUDE CONSEQUENCES OF STATE, LOCAL OR OTHER TAX
LAWS OR SPECIAL CONSEQUENCES TO PARTICULAR SHAREHOLDERS HAVING SPECIAL
SITUATIONS. SHAREHOLDERS OF CITIZENS SHOULD CONSULT THEIR OWN TAX ADVISERS
REGARDING SPECIFIC TAX CONSEQUENCES OF THE MERGER TO THEM, INCLUDING THE
APPLICATION AND EFFECT OF FEDERAL, STATE AND LOCAL TAX LAWS AND TAX CONSEQUENCES
OF SUBSEQUENT SALES OF FNB COMMON STOCK.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         GENERAL. Certain members of Citizens' management and of the Citizens
Board have interests in the merger that are in addition to any interests they
may have as shareholders of Citizens generally. These interests include, among
others, provisions in the Merger Agreement relating to the management of certain
FNB subsidiaries after the Effective Time, election or appointment of all
members of the Citizens Board to the board of directors of First National Bank
of Florida, a subsidiary of Southwest, certain proposed employment agreements
and other employee benefits, and indemnification of Citizens directors and
officers, as hereinafter described.

         MANAGEMENT POST-MERGER; CITIZENS EMPLOYMENT AGREEMENTS. FNB has agreed
to cause all of the Citizens directors to be elected to the Board of Directors
of First National Bank of Florida ("First National"), a banking subsidiary of
Southwest, for a one-year term following consummation of the merger.

         After the Effective Time of the merger, Citizens Bank & Trust, a wholly
owned subsidiary of Citizens, will be merged with and into First National.

         In connection with the proposed merger, David P. Stone, President of
Citizens, has entered into an employment agreement with FNB, contingent upon the
consummation of the merger. Under this employment agreement, Mr. Stone will,
among other benefits, (i) receive a $290,000 bonus upon the consummation of the
merger in waiver of his right under his employment agreement with Citizens to
receive the Termination Bonus, (ii) be employed for a term of two years, which
term automatically renews for successive one year terms unless sooner terminated
upon notice sent at least 90 days in advance of the end of the then current
term, and (iii) receive a base annual salary of $145,000, adjusted from time to
time to reflect merit and an annual cost of living increase similar to similarly
positioned officers of FNB. FNB has agreed to assume existing employment
agreements of other employees of Citizens.

         INDEMNIFICATION. FNB has agreed that it will, following the Effective
Time, indemnify, defend, and hold harmless the current and former directors,
officers, employees, and agents of Citizens and its subsidiary against all
losses, expenses, claims, damages, or liabilities arising out of actions or
omissions occurring at or prior to the Effective Time to the fullest extent then
permitted under Florida law and by the Citizens Charter and Citizens Bylaws as
in effect on the date of the Merger Agreement, including provisions relating to
advances of expenses incurred in defense of any litigation. The Merger Agreement
further provides that Citizens shall be permitted to purchase two years of
extended coverage under its current directors and officers liability insurance
policy to provide for continued coverage of its directors and officers with
respect to matters occurring prior to the Effective Time.

         CITIZENS OPTIONS. Citizens has granted Citizens Options from time to
time to its directors and certain of its executive officers. As of the date of
this Proxy Statement-Prospectus, there are outstanding Citizens Options to
purchase up to an aggregate of 96,000 Citizens Common Shares. All of the
Citizens Options are presently exercisable. The following table sets forth, as
of [DATE] (i) the number of Citizens Common Shares subject to such Citizens
Options, (ii) the weighted average exercise price of the all Citizens Options
held by such person, and (iii) the aggregate equivalent value of such options
based on the last sales price of $______  on [DATE] for the FNB Common Stock.

S. Racine Hall                             6,000                    $10.66 (2)


- ----------------
(1)      Includes 24,000 shares at an exercise price of $10.55 per share and
         4,000 shares at an exercise price of $11.23 per share.
(2)      Includes 5,000 shares at an exercise price of $10.55 per share and
         1,000 shares at an exercise price of $11.23 per share.

         Citizens Options to purchase up to 10,000 Citizens Common Shares are
held by former directors of Citizens. The Merger Agreement provides that all
outstanding Citizens Options not exercised before the Effective Time will be
converted at the Exchange Ratio into options to purchase shares of FNB Common
Stock, at a proportionately adjusted per share exercise price.

         OTHER MATTERS RELATING TO CITIZENS EMPLOYEE BENEFIT PLANS. The Merger
Agreement also provides that, following the Effective Time, all Citizens
employees shall become employees of First National and that Southwest will
provide generally to officers and employees of Citizens and its subsidiaries
employee benefits under employee benefit plans (other than stock option or other
plans involving the potential issuance of FNB Common Stock), on terms and
conditions which when taken as a whole are no less favorable than those
currently provided by Citizens or those currently provided by Southwest or its
subsidiaries to their similarly situated officers and employees, whichever is
more favorable to officers and employees of Citizens. After the Effective Time,
FNB or its subsidiaries will also honor in accordance with their terms all
employment, severance, consulting and other compensation contracts. FNB,
however, has entered into a new employment agreement with David P. Stone
effective as of the Effective Time. See "-- -- Management Post-Merger; Citizens
Employment Agreements" and "-- Certain Relationships and Related Transactions."

         For purposes of participation and vesting (but not benefit accrual
under any employee benefit plans of FNB and its subsidiaries other than under
the Citizens Options) under such employee benefit plans, the service of the
employees of Citizens or any of its subsidiaries prior to the Effective Time
will be treated as service with FNB or any of its subsidiaries participating in
such employee benefit plans.

STOCK OPTION AGREEMENT

         As an inducement and a condition to FNB to enter into the Merger
Agreement, FNB and Citizens entered into the Stock Option Agreement whereby
Citizens granted FNB the irrevocable Stock Option entitling FNB to purchase,
subject to certain adjustments, up to 144,292 Citizens Common Shares, at an
exercise price, subject to certain adjustments, of $35.00 per share, payable in
cash under the circumstances described below.

         The Stock Option Shares, if issued pursuant to the Stock Option
Agreement, would represent (when combined with the Citizens Common Shares
already owned by FNB) approximately 19.9% of the Citizens Common Shares issued
and outstanding.

         The number of Citizens Common Shares subject to the Stock Option will
be increased to the extent that Citizens issues additional Citizens Common
Shares (otherwise than pursuant to an exercise of the Stock Option) such that
the 



                                       27
   36

number of Citizens Common Shares subject to the Stock Option (when combined
with the Citizens Common Shares already owned by FNB) continues to equal 19.9%
of the Citizens Common Shares then issued and outstanding, after giving effect
to the issuance of Citizens Common Shares pursuant to an exercise of the Stock
Option. In the event of any change in the Citizens Common Shares by reasons of
stock dividends, split-ups, mergers, recapitalizations, combinations,
subdivisions, conversions, exchanges of shares, or the like, the type and number
of Citizens Common Shares subject to the Stock Option, and the applicable
exercise price per Stock Option Share, will be appropriately adjusted and proper
provision will be made so that, in the event that any additional Citizens Common
Shares are to be issued or otherwise become outstanding as a result of any such
change (other than pursuant to an exercise of the Stock Option), the number of
Citizens Common Shares that remain subject to the Stock Option will be increased
so that, after such issuance and together with Citizens Common Shares previously
issued pursuant to the exercise of the Stock Option and the number of shares
otherwise beneficially owned by FNB (as adjusted on account of any of the
foregoing changes in the Citizens Common Shares), equals 19.9% of the number of
Citizens Shares then issued and outstanding.

         FNB or any other holder or holders of the Stock Option (collectively,
the "Holder") may exercise the Stock Option, in whole or in part, by sending
written notice after the occurrence of an "Initial Triggering Event" and a
"Subsequent Triggering Event" prior to the occurrence of an "Exercise
Termination Event" (as such terms are defined herein). The term "Initial
Triggering Event" is defined as the occurrence of any of the following events:

                  (i)   Citizens, without having received FNB's prior written
consent, shall have entered into an agreement to engage in an Acquisition
Transaction (as hereinafter defined) with any person other than FNB or any of
its subsidiaries or the Citizens Board shall have recommended that the
stockholders of Citizens approve or accept any such Acquisition Transaction
other than as contemplated by the Merger Agreement or the Stock Option
Agreement. For purposes of the Stock Option Agreement, "Acquisition Transaction"
means (x) a merger or consolidation, or any similar transaction involving
Citizens, (y) a purchase, lease, or other acquisition of all or substantially
all of the assets or deposits of Citizens, or (z) a purchase or other
acquisition (including by way of merger, consolidation, share exchange or
otherwise) of securities representing 15% or more of the voting power of
Citizens other than securities acquired by the Citizens officers and directors;

                  (ii)  Any person (other than the officers and directors of
Citizens) other than FNB, or one of FNB's subsidiaries, acting in a fiduciary
capacity shall have acquired beneficial ownership or the right to acquire
beneficial ownership of 15% or more of the outstanding Citizens Common Shares
(the term "beneficial ownership" for purposes of the Stock Option Agreement
having the meaning assigned thereto in Section 13(d) of the Exchange Act, and
the rules and regulations thereunder pursuant to which a person is the
beneficial owner of all shares that such person has direct or indirect voting
power or investment power over whether through any contract, arrangement,
understanding, relationship or otherwise);

                  (iii) The shareholders of Citizens shall not have approved the
transactions contemplated by the Merger Agreement at the Special Meeting, or
such Special Meeting shall not have been held or shall have been canceled prior
to termination of the Merger Agreement, in either case, after the Citizens Board
shall have withdrawn or modified, or publicly announced its intention to
withdraw or modify, its recommendation that the stockholders of Citizens approve
the transactions contemplated by the Merger Agreement, or after Citizens,
without having received FNB's prior written consent, shall have authorized,
recommended, proposed, or publicly announced its intention to authorize,
recommend, or propose, to engage in an Acquisition Transaction with any person
other than FNB or one of its subsidiaries;

                  (iv)  Citizens shall have willfully and materially breached
any material covenant or obligation contained in the Merger Agreement in
anticipation of engaging in an Acquisition Transaction and such breach would
entitle FNB to terminate the Merger Agreement; or

                  (v)   Any person other than FNB or one of its subsidiaries,
other than in connection with a transaction to which FNB has given its prior
written consent, shall have filed an application or notice with the Federal
Reserve Board, or other federal or state bank regulatory authority, which
application or notice has been accepted for processing, for approval to engage
in an Acquisition Transaction.



                                       28
   37

         The term "Subsequent Triggering Event" is defined as either (A) the
acquisition by any person of beneficial ownership of 25% or more of the then
outstanding Citizens Common Shares, or (B) the occurrence of the Initial
Triggering Event described in clause (i) above, except that the percentage
referred to in subclause (z) thereof shall be 25%.

         The term "Exercise Termination Event" is defined as the occurrence of
any of the following events: (i) the Effective Time of the merger, (ii)
termination of the Merger Agreement in accordance with the terms thereof prior
to the occurrence of an Initial Triggering Event (other than termination due to
(A) the failure of FNB to satisfy a condition to closing, (B) failure to obtain
the requisite approval of Citizens shareholders following a favorable
recommendation by the Citizens Board, or (C) the withdrawal by Allen C. Ewing &
Co. of its fairness opinion), (iii) 12 months (subject to extension to obtain
regulatory approvals (for so long as the Holder is using commercially reasonable
efforts to obtain such regulatory approvals), to allow statutory waiting periods
to expire, and to avoid liability under Section 16(b) of the Exchange Act which
provides for the disgorgement to the issuer of any profit realized by an insider
as a result of a purchase and sale or sale and purchase of certain equity
securities occurring within a six-month period) after termination of the Merger
Agreement following the occurrence of an Initial Triggering Event or (iv) such
other date as to which the Holder and Citizens agree.

         After a Subsequent Triggering Event and prior to an Exercise
Termination Event, FNB (on behalf of itself or any subsequent Holder) may demand
that the Stock Option and the related Option Shares be registered under the
Securities Act. Upon such demand, Citizens must use its best efforts to effect
such registration promptly, subject to certain exceptions. FNB is entitled to
two such registrations. In addition, if at any time after the occurrence of a
Subsequent Triggering Event that occurs prior to an Exercise Termination Event,
Citizens proposes to register any of its equity securities under the Securities
Act, whether for sale for its own account or for the account of any other
person, on a form and in a manner which would permit registration of the Option
Shares for sale to the public under the Securities Act, Citizens must give
written notice to FNB of its intention to do so, describing such securities and
specifying the form and manner and the other relevant facts involved in such
proposed registration, and upon the written request of FNB, Citizens is
required, subject to certain exceptions, to use its best efforts to effect the
registration under the Securities Act of all Common Stock which Citizens has
been requested to register by FNB. Citizens is obligated to effect only one such
"piggy-back" registration.

         Under applicable law, FNB may not acquire 5% or more of the issued and
outstanding shares of Citizens Common Shares without the prior approval of the
Federal Reserve Board. In considering whether to approve the acquisition by FNB
of shares pursuant to the exercise of the Stock Option, the Federal Reserve
Board will generally apply the same standards as in considering whether to
approve the merger. See "-- Bank Regulatory Matters -- Federal Reserve Board."
Certain other regulatory approvals may also be required before such an
acquisition could be completed. FNB has submitted an application seeking Federal
Reserve Board approval of its acquisition of up to 19.9% of the outstanding
Citizens Common Shares pursuant to a potential exercise of the Stock Option.

         Upon the occurrence of a Repurchase Event (as defined herein) that
occurs prior to an Exercise Termination Event (i) at the request of the Holder
delivered prior to the Exercise Termination Event (subject to extension to
obtain regulatory approvals (for so long as the Holder is using commercially
reasonable efforts to obtain such regulatory approvals), to allow statutory
waiting periods to expire, and to avoid liability under Section 16(b) of the
Exchange Act), Citizens shall repurchase the Stock Option from the Holder at a
price ("Option Repurchase Price") equal to the amount by which (x) the
Market/Offer Price (as defined herein) exceeds (y) the Stock Option exercise
price, multiplied by the number of shares for which the Stock Option may then be
exercised; and (ii) at the request of the owner of Option Shares from time to
time (the "Owner") delivered prior to the occurrence of an Exercise Termination
Event, Citizens shall repurchase such number of Stock Option Shares from the
Owner as the Owner designates at a price per share (the "Option Share Repurchase
Price") equal to the Market/Offer Price multiplied by the number of Option
Shares so designated. "Market/Offer Price" means the highest of (A) the price
per share of Citizens Common Shares at which a tender offer or exchange offer
therefor has been made, (B) the price per share of Citizens Common Shares to be
paid by any third party pursuant to an agreement with Citizens, or (C) in the
event of the sale of all or a substantial portion of Citizens' assets, the sum
of the net price paid in such sale for such assets or deposits and the current
market value of the remaining net assets of Citizens divided by the number of
Citizens Common Shares then outstanding. In determining the Market/Offer Price,
the value of consideration other than cash shall be determined by a nationally
recognized investment banking firm selected by the Holder or Owner, as the case
may be. "Repurchase Event" means (i) the consummation of



                                       29
   38

certain mergers, consolidations or similar transactions involving Citizens or
any purchase, transfer or other acquisition of all or a substantial portion of
the assets or deposits of Citizens by any person other than FNB or one of its
subsidiaries, (such transactions being more fully described in clauses (i), (ii)
and (iii) of the paragraph immediately following this paragraph) or (ii) the
acquisition by any person, other than FNB or any of its subsidiaries, of
beneficial ownership of 50% or more of the then outstanding Citizens Common
Shares.

         In the event that prior to an Exercise Termination Event, Citizens
enters into an agreement (i) to consolidate with or merge into any person other
than FNB or one of its subsidiaries and shall not be the continuing or surviving
corporation of such consolidation or merger, (ii) to permit any person other
than FNB or one of its subsidiaries to merge into Citizens with Citizens as the
continuing or surviving corporation, but in connection therewith the then
outstanding Citizens Common Shares are changed into or exchanged for securities
of any other person or cash or any other property, or the then outstanding
Citizens Common Shares after such merger represent less than 50% of the
outstanding shares and share equivalents of the merged company, or (iii) to sell
or transfer all or substantially all of its or a significant subsidiary's assets
or deposits to any person other than FNB or one of its subsidiaries, then such
agreement shall provide that the Stock Option be converted into or exchanged for
an option (a "Substitute Option") to purchase shares of common stock of, at the
Holder's option, either (x) the continuing or surviving corporation of a merger
or consolidation or the transferee of all or substantially all of Citizens'
assets or deposits, or (y) the person controlling such continuing or surviving
corporation or transferee. The number of shares subject to the Substitute Option
and the exercise price per share will be determined in accordance with a formula
in the Stock Option Agreement. To the extent possible, the Substitute Option
will contain terms and conditions that are the same as those in the Stock
Option.

         The issuer of the Substitute Option will be required to repurchase the
Substitute Option at the request of the holder thereof and to repurchase any
shares of such issuer's common stock ("Substitute Common Stock") issued upon
exercise of a Substitute Option ("Substitute Shares") at the request of the
owner thereof. The repurchase price for a Substitute Option will equal the
amount by which (A) the Highest Closing Price (as defined herein) exceeds (B)
the exercise price of the Substitute Option, multiplied by the number of shares
of Substitute Common Stock for which the Substitute Option may then be
exercised. The repurchase price for the Substitute Shares shall equal the
Highest Closing Price multiplied by the number of Substitute Shares to be
repurchased. As used herein, "Highest Closing Price" means the highest closing
price for shares of Substitute Common Stock within the three-month period
immediately preceding the date the holder gives notice of the required
repurchase of the Substitute Option or the owner gives notice of the required
repurchase of Substitute Shares, as the case may be.

         Neither Citizens nor FNB may assign any of its respective rights and
obligations under the Stock Option Agreement or the Stock Option to any other
person without the other party's express written consent, except that if a
Subsequent Triggering Event occurs prior to termination of the Stock Option,
FNB, subject to the express provisions of the Stock Option Agreement, may assign
in whole or in part its rights and obligations thereunder; provided, however,
that until 30 days after the Federal Reserve Board approves an application by
FNB to acquire the Stock Option Shares, FNB may not assign its rights under the
Stock Option except in (i) a widely dispersed public distribution, (ii) a
private placement in which no one party acquires the right to purchase in excess
of 2% of the voting shares of Citizens, (iii) an assignment to a single party
(such as a broker or investment banker) for the purpose of conducting a widely
dispersed public distribution on FNB's behalf, or (iv) any other manner approved
by the Federal Reserve Board.

         No shares shall be issued pursuant to the exercise of the Stock Option
if (i) at the time of the Initial Triggering Event and at the time of exercise,
FNB is in material breach under the Merger Agreement, or (ii) a preliminary or
permanent injunction has been issued by a court of proper jurisdiction enjoining
such exercise.

         The rights and obligations of Citizens and FNB under the Stock Option
Agreement are subject to receipt of any required regulatory approvals, and both
parties have agreed to use their best efforts in connection therewith. These
include, but are not limited to, applying to the Federal Reserve Board for
approval to acquire the Stock Option Shares.

         The purpose of the Stock Option Agreement and the Stock Option is to
increase the likelihood that the merger will occur by making it more difficult
for another party to acquire Citizens. The ability of FNB to exercise the Stock
Option and to cause, subject to certain adjustments, up to an additional 144,292
Citizens Common Shares to be issued 


                                       30
   39

may be considered a deterrent to other potential acquisitions of control of
Citizens, as it is likely to increase the cost of an acquisition of all the
Citizens Common Shares which would then be outstanding.

DISSENTERS' RIGHTS OF CITIZENS SHAREHOLDERS

         The following summary does not purport to be a complete statement of
the procedure to be followed by Citizens shareholders desiring to exercise
dissenters' rights and is qualified in its entirety by reference to the
provisions of Sections 1301-1320 of the FBCA, the full text of which is attached
as Appendix D to this Proxy Statement-Prospectus. Since the preservation and
exercise of dissenters' rights require strict adherence to the provisions of
these laws, Citizens shareholders who might desire to exercise such rights
should review such laws carefully, timely consult their own legal advisor, and
strictly follow the provisions of Florida law. A Citizens shareholder's failure
to follow any of the applicable procedures may result in termination or waiver
of their dissenters' rights.

         FNB has the right to terminate the Merger Agreement if dissenters'
rights claimed under the FBCA aggregate more than 10% of the issued and
outstanding Citizens Common Shares. See "The Merger -Modification, Waiver, and
Termination."

         Only Citizens shareholders who are shareholders of record as of the
close of business on _____________, 1998, the Record Date for the Special
Meeting, will have the right to vote on the Merger Agreement and, as a result,
be entitled to exercise dissenters' rights under applicable Florida law. A
shareholder of Citizens who wishes to exercise their dissenters' rights under
Florida law must (i) prior to the vote at the Special Meeting, deliver written
notification to Citizens of their intent to demand payment for their shares if
the merger is consummated, and (ii) not vote their shares in favor of the Merger
Agreement. Neither a vote against approval of the merger nor an abstention from
voting constitutes a notice of intent to demand payment sufficient to assert
dissenters' rights under Florida law. In addition, since proxies that are signed
and returned without specification as to how they should be voted will be voted
in favor of the Merger Agreement, a Citizens shareholder who returns such a
proxy will not be entitled to exercise dissenters' rights unless he revokes that
proxy prior to the vote of Citizens shareholders on the Merger Agreement.

         A Citizens shareholder wishing to exercise his dissenters' rights
should, prior to the vote at the Special Meeting, deliver the written
notification described above to the Secretary of Citizens at 1150 Cleveland
Street, Clearwater, Florida 33755, attention: S. Racine Hall.

         Citizens shareholders who perfect their dissenters' rights will be
entitled to demand payment of the "fair value" (determined as described below)
for their Citizens Common Shares in lieu of receiving shares of FNB Common Stock
in the merger. "Fair value" is defined as the value of the Citizens Common
Shares as of the close of business on the day prior to the date on which the
Citizens shareholders authorize the Merger, excluding any appreciation or
depreciation in anticipation of the corporate action unless exclusion would be
inequitable. Holders of Citizens Common Shares who intend to exercise their
dissenters' rights should bear in mind that the "fair value" of their Citizens
Common Shares could be more than, the same as, or less than, the consideration
they would receive pursuant to the Merger Agreement.

         If Citizens shareholders approve the Merger Agreement at the Special
Meeting, Citizens must, within 10 days thereafter, give written notice of such
approval to each Citizens shareholder who notified Citizens of their intent to
demand payment and who did not vote their shares in favor of the Merger
Agreement. Within 20 days after such notice from Citizens, each such shareholder
who elects to dissent must file with Citizens a notice of election to dissent
(an "Election Notice"), stating their name and address, the number of shares
with respect to which they dissent and a demand for payment of the fair value
for their shares. The dissenting shareholder must also deposit his Citizens
stock certificates with Citizens simultaneously with the filing of his Election
Notice.

         Within ten days after the expiration of the period for filing an
Election Notice or within ten days after the Merger is effected, whichever is
later, (but in no case later than 90 days after Citizens shareholders approve
the Merger Agreement), Citizens must make a written offer to pay each dissenting
shareholder who has filed an Election Notice an amount that Citizens estimates
to be the fair value for their shares. The Citizens offer must be accompanied by
the Citizens current balance sheet and profit and loss statement. If the Merger
has not been consummated within 90 days 



                                       31
   40

after the date on which the Citizens shareholders approve the Merger Agreement,
the Citizens offer of payment may be made conditional upon the consummation of
the Merger.

         If within 30 days after Citizens makes its offer to pay fair value, the
dissenting shareholder accepts the Citizens offer, payment for their shares
shall be made within 90 days of the Citizens offer or the consummation of the
Merger, whichever is later. Upon payment of the agreed value, the dissenting
shareholder ceases to have any interest in their shares.

         If Citizens fails to make an offer within the prescribed period or if
it makes the offer and any dissenting shareholder fails to accept the offer
within the 30-day period, Citizens shall, within 30 days after receipt of an
Election Notice given within 60 days after the consummation of the merger, or
may, at its election, at any time within 60 days after the consummation of the
merger, petition the Circuit Court of Pinellas County, Florida, requesting that
the fair value of such shares be determined. The Court shall also determine
whether each dissenting shareholder is entitled to payment for their shares. If
Citizens fails to institute the proceeding as required, any dissenting
shareholder may do so in the name of Citizens. All dissenting shareholders who
have not agreed to accept the Citizens offer will be made parties to the action
against their shares and are entitled to judgment against Citizens for the
amount of the fair value of their shares. The Court may appoint persons as
appraisers to receive evidence and recommend a decision on the question of fair
value. Citizens will pay each dissenting shareholder the amount found due within
10 days after the Court's final determination. Upon payment of the judgment, the
dissenting shareholders shall cease to have any interest in their shares.

         The costs and expenses of any such proceeding, including reasonable
compensation for appraisers, but excluding the fees for counsel and experts used
by any party shall be determined by the Court and assessed against Citizens.
However, the Court may assess all or any part of such costs and expenses against
a shareholder if the Court finds that the shareholder's refusal to accept the
Citizens offer was arbitrary, vexatious, or not in good faith. If the Court
determines that the fair value of the shares materially exceeds the amount of
the Citizens offer or if Citizens fails to make an offer, the Court may award to
any dissenting shareholder reasonable compensation for attorneys and experts
employed by such shareholder in the proceeding.

         Once a dissenting shareholder files an Election Notice with Citizens as
described above, such shareholder is only entitled to payment as provided by
Section 607.1320 of the FBCA and is not entitled to vote or exercise any other
rights as a shareholder. A dissenting shareholder may withdraw their Election
Notice in writing at any time before Citizens makes its offer to pay for their
shares. After Citizens makes their offer, the Election Notice may be withdrawn
only if Citizens consents to the withdrawal.

         The right of a dissenting shareholder to be paid fair value of his
shares will cease, and he will be reinstated as a shareholder, with all rights
as described in the statute as of the date on which he filed the Election
Notice, if one of the following events occurs: (i) the Election Notice is
withdrawn; (ii) the Merger Agreement is abandoned or rescinded or the Citizens
shareholders revoke the authority to effect the Merger; (iii) no demand or
petition of determining fair value by a court has been made or filed within the
time limits provided under Section 607.1320 of the FBCA; or (iv) a court of
competent jurisdiction determines that the dissenting shareholder is not
entitled to the relief provided by that Section.

         Once the merger is effected, FNB will be subject to, and will be
required to perform, all of the obligations of Citizens described above.
Accordingly, on or after the effective date of the merger, dissenting
shareholders of Citizens should send any communications regarding their rights
to David B. Mogle, Secretary, F.N.B. Corporation, One F.N.B. Boulevard,
Hermitage, Pennsylvania 16148. All communications should be signed by or on
behalf of the dissenting Citizens shareholder in the form in which his shares
are registered on Citizens' books.

ACCOUNTING TREATMENT

         It is intended that the merger will be accounted for as a
pooling-of-interests under GAAP. Citizens and FNB have agreed to use their
reasonable efforts to cause the merger, and to take no action that would cause
the merger not, to qualify for pooling-of-interests treatment.

         Under the pooling-of-interests method of accounting, the historical
basis of the assets and liabilities of FNB and Citizens will be combined at the
Effective Time of the merger and carried forward at their previously recorded
amounts, 




                                       32
   41

and the shareholders' equity accounts of Citizens and FNB will be combined on
FNB's consolidated balance sheet and no goodwill or other intangible assets will
be created.

BANK REGULATORY MATTERS

         FEDERAL RESERVE BOARD AND OFFICE OF THE COMPTROLLER OF THE CURRENCY.
The merger is subject to prior approval by the Federal Reserve Board and the
Office of the Comptroller of the Currency (the "OCC"). In determining whether to
approve a transaction such as the merger, the Federal Reserve Board and the OCC
take into consideration the financial and managerial resources (including the
competence, experience and integrity of the officers, directors and principal
shareholders) and future prospects of the existing and proposed institutions and
the convenience and needs of the communities to be served. In considering
financial resources and future prospects, the Federal Reserve Board and the OCC
will, among other things, evaluate the adequacy of the capital levels of the
parties to a proposed transaction.

         The Federal Reserve Board and the OCC are prohibited from approving a
merger if it would result in a monopoly or would be in furtherance of any
combination or conspiracy to monopolize or to attempt to monopolize the business
of banking in any part of the United States, or if its effect in any section of
the country would be substantially to lessen competition or to tend to create a
monopoly, or if it would in any other manner result in a restraint of trade,
unless the Federal Reserve Board finds that the anti-competitive effects of a
merger are clearly outweighed in the public interest by the probable effect of
the transaction in meeting the convenience and needs of the communities to be
served. In addition, under the Community Reinvestment Act of 1977, as amended
(the "CRA"), the Federal Reserve Board and the OCC must take into account the
record of performance of the existing institutions in meeting the credit needs
of the entire community, including low- and moderate-income neighborhoods,
served by such institutions. Three of FNB's nine banking subsidiaries have an
outstanding CRA rating with the appropriate federal regulator. The other six of
FNB's banking subsidiaries have a satisfactory rating with the appropriate
federal regulator.

         Applicable federal law provides for the publication of notice and
public comment on applications filed with the Federal Reserve Board and the OCC
and authorizes each agency to permit interested parties to intervene in the
proceedings. If an interested party is permitted to intervene, such intervention
could delay the regulatory approvals required for consummation of the merger.

         The merger generally may not be consummated until after 15 days
following the date of applicable federal regulatory approval, during which time
the United States Department of Justice may challenge the merger on antitrust
grounds. The commencement of an antitrust action would stay the effectiveness of
the regulatory agency's approval unless a court specifically ordered otherwise.
FNB and Citizens believe that the merger does not raise substantial antitrust or
other significant regulatory concerns and that any divestitures that may be
required in order to consummate the merger will not be material to the financial
condition or results of operations of FNB or Citizens prior to the Effective
Time, or FNB after the Effective Time.

         In addition, FNB's right to exercise the Stock Option under the Stock
Option Agreement is also subject to the prior approval of the Federal Reserve
Board, because the exercise of the Stock Option under the Stock Option Agreement
would result in FNB owning more than 5% of the outstanding Citizens Common
Shares. In considering whether to approve FNB's right to exercise the Stock
Option, the Federal Reserve Board would generally apply the same statutory
criteria it would apply to its consideration of approval of the merger.

         STATUS OF REGULATORY APPROVALS AND OTHER INFORMATION. FNB and Citizens
have filed all applications and notices and have taken (or will take) other
appropriate action with respect to any requisite approvals or other action of
any governmental authority. FNB has submitted an application seeking Federal
Reserve Board and OCC approval of the merger and seeking Federal Reserve Board
approval of its acquisition of up to 19.9% of the outstanding Citizens Common
Shares pursuant to a potential exercise of the Stock Option.

         The Merger Agreement provides that the obligation of each of FNB and
Citizens to consummate the merger is conditioned upon the receipt of all
requisite regulatory approvals, including the approvals of the Federal Reserve
Board and OCC. There can be no assurance that any governmental agency will
approve or take any other required action with respect to the merger, and, if
approvals are received or action is taken, there can be no assurance as to the
date of such approvals or action, that such approvals or action will not be
conditioned upon matters that would cause the parties to



                                       33
   42

abandon the merger, or that no action will be brought challenging such approvals
or action, including a challenge by the United States Department of Justice or,
if such a challenge is made, the result thereof.

         FNB and Citizens are not aware of any governmental approvals or actions
that may be required for consummation of the merger other than as described
above. Should any other approval or action be required, FNB and Citizens
currently contemplate that such approval or action would be sought.

         THE MERGER CANNOT PROCEED IN THE ABSENCE OF THE REQUISITE REGULATORY
APPROVALS. THERE CAN BE NO ASSURANCES THAT SUCH REGULATORY APPROVALS WILL BE
OBTAINED OR AS TO THE DATES OF ANY SUCH APPROVALS. THERE CAN ALSO BE NO
ASSURANCE THAT SUCH APPROVALS WILL NOT CONTAIN A CONDITION OR REQUIREMENT WHICH
CAUSES SUCH APPROVALS TO FAIL TO SATISFY THE CONDITIONS SET FORTH IN THE MERGER
AGREEMENT. SEE "-- CONDITIONS PRECEDENT TO THE MERGER." THERE CAN LIKEWISE BE NO
ASSURANCE THAT THE UNITED STATES DEPARTMENT OF JUSTICE WILL NOT CHALLENGE THE
MERGER, OR, IF SUCH A CHALLENGE IS MADE, AS TO THE RESULT THEREOF.

         See "-- Effective Time of the Merger," "-- Conditions Precedent to the
Merger" and "-- Modification, Waiver and Termination."

RESTRICTIONS ON RESALES BY AFFILIATES

         The shares of FNB Common Stock to be issued to shareholders of Citizens
in the merger have been registered under the Securities Act. Such shares may be
traded freely and without restriction by those shareholders not deemed to be
"affiliates" of Citizens or FNB as that term is defined under the Securities
Act. Any subsequent transfer of such shares, however, by any person who is an
affiliate of Citizens at the time the merger is submitted for vote or consent of
the shareholders of Citizens will, under existing law, require either (a) the
further registration under the Securities Act of the shares of FNB Common Stock
to be transferred, (b) compliance with Rule 145 promulgated under the Securities
Act (permitting limited sales under certain circumstances), or (c) the
availability of another exemption from registration. An "affiliate" of Citizens,
as defined by the rules promulgated pursuant to the Securities Act, is a person
who directly, or indirectly through one or more intermediaries, controls, is
controlled by, or is under common control with Citizens. In addition, under
requirements for pooling-of-interests method of accounting, the shares of FNB
Common Stock issued to affiliates are not transferable until such time as
financial results covering at least 30 days of combined operations of FNB and
Citizens have been published. The foregoing restrictions are expected to apply
to the directors, executive officers, and the beneficial holders of 10% or more
of the Citizens Common Shares (and to certain relatives or the spouse of any
such person and any trusts, estates, corporations, or other entities in which
any such person has a 10% or greater beneficial or equity interest). Stop
transfer instructions will be given by FNB to the transfer agent with respect to
the FNB Common Stock to be received by persons subject to the restrictions
described above. Citizens has agreed that, not later than 30 days prior to the
Effective Time, it will use its best efforts to obtain from each of those
persons identified by Citizens as affiliates appropriate agreements that each
such individual will not make any further sales of shares of FNB Common Stock
received upon consummation of the merger except in compliance with the
restrictions described in this paragraph.

VOLUNTARY DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN

         FNB approved a dividend reinvestment and direct stock purchase plan
(the "1998 DRP") which became effective in April 1998 and replaced the existing
dividend reinvestment plan. The 1998 DRP is available to existing FNB
shareholders and shareholders of Citizens who receive shares of FNB Common Stock
in the merger, as well as persons who are not already shareholders, and permits
participants to purchase shares of FNB Common Stock through reinvestment of
dividends on their shares of FNB Common Stock and/or optional cash payments and
permits participants to have their shares enrolled in the 1998 DRP held in
book-entry form by the plan administrator.

MARKET PRICES

         Since June 16, 1997, FNB Common Stock has traded on the Nasdaq National
Market under the trading symbol "FBAN." Prior to June 16, 1997, the FNB Common
Stock traded on the Nasdaq SmallCap Market under the same symbol. Stock prices
have been adjusted to reflect a 5% stock dividend paid on May 31, 1997. As of
June 30, 1998, FNB Common Stock was held of record by approximately 6,400
persons. The following table sets forth the high ask and high bid prices of the
FNB Common Stock as reported by the Nasdaq National Market for the periods
indicated.

         There is no established public trading market for the Citizens Common
Shares. As of the Record Date, there were 580,795 shares of Citizens Common
Shares issued and outstanding held by 201 holders of record. According to
records kept by management, since January, 1997, there have been only
approximately 61 trades in the Citizens Common Shares involving an aggregate of
66,085 shares. To the best of management's knowledge, which is based on limited
and incomplete information, Citizens believes that recently negotiated sales of
citizens Common Shares have ranged between $19.00 and $25.00 per share. In view
of the extremely limited volume of transactions and the lack of reliable pricing
information (because such information is not required to be forwarded to
Citizens), there is no assurance that the stated prices paid for the Citizens
Common Shares provide a reliable or relevant indication of the value of Citizens
Common Shares.

DIVIDENDS

         The following table sets forth the per share cash dividends declared on
FNB Common Stock for the periods indicated. Citizens has not paid cash dividends
on the Citizens Common Shares during the past two years. The FNB dividends have
been adjusted to reflect the 5% FNB Stock Dividend. The ability of either FNB or
Citizens to pay dividends to its shareholders is subject to certain
restrictions. See "INFORMATION ABOUT FNB" and "INFORMATION ABOUT CITIZENS."

                              INFORMATION ABOUT FNB

         FNB is a financial services holding company organized under the laws of
the Commonwealth of Pennsylvania and headquartered in Hermitage, Pennsylvania.
It provides a broad range of financial services to its customers through its
bank and consumer finance subsidiaries in Pennsylvania, southwestern Florida,
eastern Ohio and southwestern New York. FNB's main office is located at One
F.N.B. Boulevard, Hermitage, Pennsylvania 16148 and its telephone number is
(724) 981-6000.

         FNB was formed in 1974 as the holding company of its then sole
subsidiary, First National, formerly First National Bank of Mercer County. Since
its formation, FNB has acquired and currently operates eight other bank
subsidiaries and one consumer finance company in Pennsylvania, southwestern
Florida, eastern Ohio and southwestern New York. On January 21, 1997, FNB
affiliated with Southwest, a Florida corporation and registered bank holding
company under the Bank Holding Company Act ("BHCA"), with banking subsidiaries
located in Naples and Cape Coral, Florida. On April 18, 1997, FNB affiliated
with West Coast Bancorp, Inc. ("WCBI"), a Florida corporation and registered
bank holding company under the BHCA, located in Cape Coral, Florida. On June 30,
1997, FNB sold its wholly owned subsidiary, Bucktail Bank and Trust Company, a
Pennsylvania state-chartered bank to Sun Bancorp, Inc. ("Sun") in exchange for
13.8% of the outstanding stock of Sun. On October 17, 1997, FNB affiliated with
Indian Rocks State Bank (which was subsequently converted to a national bank and
renamed First National Bank of Florida), a Florida state bank located in Largo,
Florida with assets of approximately $81 million. On November 20, 1997, FNB
affiliated with Mercantile Bank of Southwest Florida, a Florida state bank
located in Naples, Florida with assets of approximately $122 million. On January
20, 1998, FNB affiliated with West Coast Bank, a Florida state bank located in
Sarasota, Florida with assets of approximately $107 million. On May 29, 1998,
FNB completed its affiliation with Seminole Bank, a Florida state bank, located
in Seminole, Florida with assets of approximately $91 million. After considering
the acquisition of Seminole, on a consolidated basis, FNB had approximately $2.9
billion in consolidated assets, approximately $2.5 billion in deposits and 111
offices.

         FNB, through its subsidiaries, provides a full range of financial
services, principally to consumers and small- to medium-sized businesses in its
market areas. FNB's business strategy has been to focus primarily on providing
quality, community-based financial services adapted to the needs of each of the
markets it serves. FNB has emphasized its community orientation by generally
preserving the names and local boards of directors of its subsidiaries, by
allowing its subsidiaries autonomy in decision-making and thus enabling them to
respond to customer requests more quickly, and by concentrating on transactions
within its market areas. However, while FNB has sought to preserve the
identities and autonomy of its subsidiaries, it has established centralized
credit analysis, loan review, investment, audit and data





                                       36
   45

processing functions. The centralization of these processes has enabled FNB to
maintain consistent quality of these functions and to achieve certain economies
of scale.

         FNB's lending philosophy is to minimize credit losses by following
uniform credit approval standards (which include independent analysis of
realizable collateral value), diversifying its loan portfolio, maintaining a
relatively modest average loan size and conducting ongoing review and management
of the loan portfolio. FNB is an active residential mortgage lender, and its
commercial loans are generally to established local businesses. FNB does not
have a significant amount of construction loans, and has no highly leveraged
transaction loans or loans to foreign countries.

         No material portion of the deposits of FNB's bank subsidiaries has been
obtained from a single or small group of customers, and the loss of any
customer's deposits or a small group of customers' deposits would not have a
material adverse effect on the business of FNB.

         FNB has four other operating subsidiaries, Penn-Ohio Life Insurance
Company ("Penn-Ohio"), Mortgage Service Corporation, F.N.B. Building Corporation
and F.N.B. Investment Corporation. Penn-Ohio underwrites, as a reinsurer, credit
life and accident and health insurance sold by FNB's subsidiaries. These
activities are incidental to FNB banking business. Mortgage Service Corporation
services mortgage loans for unaffiliated financial institutions and F.N.B.
Building Corporation owns real estate that is leased to certain of its
affiliates. FNB Investment Corporation holds equity securities and other
miscellaneous assets on behalf of FNB.

         As of July 1, 1998, FNB and its subsidiaries had approximately 1,200
full-time equivalent employees.

         As part of its operations, FNB regularly evaluates the potential
acquisition of, and holds discussions with, various financial institutions and
other businesses of a type eligible for bank holding company investment. In
addition, FNB regularly analyzes the values of, and submits bids for, the
acquisition of customer-based funds and other liabilities and assets of such
financial institutions and other businesses. As a general rule, FNB publicly
announces such material acquisitions when a definitive agreement has been
reached.

         For further information about FNB, reference is made to the FNB Annual
Report on Form 10-K for the year ended December 31, 1997, Quarterly Report on
Form 10-Q for the three months ended March 31, 1998 and the Current Reports on
Form 8-K filed on February 13, 1998, April 3, 1998 and July 6, 1998, all of

                           INFORMATION ABOUT CITIZENS

GENERAL

         Citizens, a Florida corporation organized on August 29, 1991, is a bank
holding company registered under the BHCA whose primary subsidiary and principal
asset is the Bank, a Florida state-chartered banking corporation. Citizens owns
all of the outstanding capital stock of the Bank. Through its ownership of the
Bank, Citizens is engaged in a general commercial banking business and its
primary source of earnings is derived from income generated by the Bank. In
addition to the Bank, Citizens also owns CBORE, Inc., a Florida corporation and
wholly-owned subsidiary of Citizens formed in July 1997 for the sole purpose of
holding the ownership of foreclosed real estate. At December 31, 1997, and March
31, 1998, CBORE, Inc. held no foreclosed real estate and was engaged in no
substantial business activities. As of March 31, 1998, Citizens, on a
consolidated basis, had total assets of approximately $121.2 million, net
portfolio loans of approximately $72.7 million, total deposits of approximately
$103.4 million, and shareholders' equity of approximately $11.5 million. Unless
the context otherwise requires, references herein to Citizens include Citizens
and its subsidiaries on a consolidated basis.




                                       37
   46

         The Bank, headquartered in Clearwater, Florida, was organized in 1986
and is not a member of the Federal Reserve System. The Bank engages in general
commercial banking and related businesses from its six full service banking
locations located in Pinellas County, Florida. Three of these offices, including
the main office, are located in Clearwater, Florida. The remaining branches are
located in Dunedin, Belleair, and Palm Harbor, Florida.

         The business of the Bank consists of attracting deposits from the
general public in the areas served by its banking offices and applying those
deposits, together with funds derived from other sources, to the origination of
a variety of consumer, commercial, and residential real estate loans in Pinellas
County and surrounding areas. The revenues of the Bank are derived primarily
from interest on, and fees received in connection with, its lending activities,
from interest and dividends from investment securities and short-term
investments, and from fees received from its fiduciary and trust services. The
principal sources of funds for the Bank's lending and investment activities are
its deposits, amortization and prepayment of loans, and the maturity and
repayments of investment securities. The principal expenses of the Bank are the
interest paid on deposits and operating and general and administrative expenses.

         As a general commercial bank, the Bank offers a broad range of
commercial, consumer, and residential real estate loans, and provides a variety
of corporate and personal banking services to individuals, businesses, and other
institutions located in its market area. In order to attract funds for loans,
the Bank's deposit services include certificates of deposit, individual
retirement accounts ("IRAs") and other time deposits, checking and other demand
deposit accounts, interest paying checking accounts ("NOW accounts"), savings
accounts and money market accounts. The transaction accounts and time
certificates are tailored to the principal market areas at rates competitive to
those in the area. All deposit accounts are insured by the FDIC up to the
maximum limits permitted by law. The Bank also offers ATM cards (with access to
local, state, national, and international networks), safe deposit boxes, wire
transfers, direct deposit, and automatic drafts for various accounts. In
addition, the Bank has a trust department which specializes in personal trust
and estate services. Securities and other property held by the trust department
in a fiduciary capacity do not constitute assets of the Bank and are not
included in balance sheets of Citizens.

         The Bank is subject to examination and comprehensive regulation by the
Florida Department of Banking and Finance (the "Department") and the FDIC. As is
the case with banking institutions generally, the Bank's operations are
materially and significantly influenced by general economic conditions and by
related monetary and fiscal policies of financial institution regulatory
agencies, including the FDIC and the FRB. Deposit flows and cost of funds are
influenced by interest rates on competing investments and general market rates
of interest. Lending activities are affected by the demand for financing of real
estate and other types of loans, which in turn are affected by the interest
rates at which such financing may be offered and other factors affecting local
demand and availability of funds.

MARKET AREA

         The Bank's operations are based in Clearwater, Florida and its market
area covers all of Pinellas County. Management of the Bank believes that its
principal markets have been (i) the expanding residential market within its
primary market area, (ii) the established commercial, small business, and
professionals in its market area, and (iii) affluent individuals for whom
fiduciary and trust services are provided. Businesses and individuals are
solicited through the personal efforts of the Bank's directors and officers.

LENDING ACTIVITIES

         The primary source of income generated by the Bank is from the interest
earned from both its loan and investment portfolios. To develop business, the
Bank relies to a great extent on the personalized approach of its directors and
officers who have extensive business and personal contacts in the community.
Citizens has attempted to maintain diversification when considering investments
and the approval of loan requests. Emphasis has been placed on the borrower's
ability to generate cash flow sufficient to support its debt obligations and
other cash related expenses.



                                       38
   47

        Lending activities include commercial and consumer loans, and loans for
residential purposes. Commercial loans include collateralized and
uncollateralized loans for working capital (including inventory and
receivables), business expansion (including real estate acquisitions and
improvements), and purchases of equipment and machinery. Consumer loans include
collateralized and uncollateralized loans for the purchase of automobiles,
boats, home improvement, and personal investments. The Bank provides personal
and corporate credit cards, VISA or MasterCard credit cards, as issued by a
correspondent bank which assumes all liabilities relating to underwriting of the
credit applicant. The Bank also originates a variety of residential real estate
loans, including the origination of conventional mortgages collateralized by
first mortgage liens to enable borrowers to purchase, refinance, or to improve
homes or real property. In addition, such loans include those made to individual
borrowers collateralized by first mortgage interests on unimproved parcels of
real estate zoned for residential homes on which such borrower intends to erect
their personal residence. To a lesser extent, the Bank also has made land
acquisition and development loans and construction loans to developers of
residential properties for construction of residential subdivisions and
multi-family residential projects.

         At March 31, 1998, Citizens net loan portfolio was $72.7 million
representing 60.0% of total assets. As of such date, the Bank's net loan
portfolio consisted of 23.4% commercial, loans, 66.1% real-estate mortgage
loans, 0.7% real estate construction loans and 9.8% installment or consumer
loans.

COMPETITION

         The Bank encounters strong competition both in attracting deposits and
in the origination of loans. The deregulation of the banking industry and the
widespread enactment of state laws which permit multi-bank holding companies as
well as the availability of nationwide interstate banking has created a highly
competitive environment for financial service providers in the Bank's primary
market area. In one or more aspects of its business, the Bank has competed with
other commercial banks, savings and loan associations, credit unions, finance
companies, mutual funds, insurance companies, brokerage and investment banking
companies, and other financial intermediaries operating in its market area and
elsewhere. Most of these competitors, some of which are affiliated with large
bank holding companies, have substantially greater resources and lending limits,
and may offer certain services that the Bank does not provide. In addition, many
of The Company's non-bank competitors are not subject to the same extensive
federal regulations that govern bank holding companies and state chartered and
federally insured banks.

         The Bank's primary market area is served by 25 commercial banks with
262 offices, 6 savings and loan associations with 34 offices, for a total of 296
offices. As of June 30, 1997, the total reported deposits in the primary market
area were approximately $13 billion.

         Competition among financial institutions is based upon interest rates
offered on deposit accounts, interest rates charged on loans and other credit
and service charges, the quality of the services rendered, the convenience of
banking facilities, and, in the case of loans to commercial borrowers, relative
lending limits.

EMPLOYEES

         At March 31, 1998, the Bank employed 61 full-time and 8 part-time
employees. None of these employees are covered by a collective bargaining
agreement and management believes that its employee relations are good.

         The principal executive and administrative offices of Citizens and the
Bank are located at 1150 Cleveland Street, Clearwater, Florida 33755 and such

options to renew the lease for additional six-year terms. Under the lease,
Citizens pays a base rent of approximately $4,757 per month. The rent is
adjustable every two years based upon changes in the consumer price index. The
Bank is responsible for utilities and maintenance of the interior of the
facility. The Bank subleases approximately 2,200 square feet of this facility to
a law firm for approximately $2,492 per month.

LEGAL PROCEEDINGS

         Citizens and the Bank are periodically parties to or otherwise involved
in legal proceedings arising in the normal course of business, such as claims to
enforce liens, foreclose on loan defaults, claims involving the making and
servicing of real property loans, and other issues incident to the Bank's
business. Management is not aware of any proceeding threatened or pending
against Citizens or the Bank which, if determined adversely, would have a
material effect on the business or financial position of Citizens or the Bank.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The Bank has had various loan and other banking transactions in the ordinary
course of business with the directors, executive officers, and principal
shareholders of Citizens (or an associate of such person). All such
transactions: (i) have been made in the ordinary course of business; (ii) have
been made on substantially the same terms, including interest rates and
collateral on loans, as those prevailing at the time for comparable transactions
with unrelated persons; and (iii) in the opinion of management do not involve
more than the normal risk of collectibility or present other unfavorable
features. At March 31, 1998, the total dollar amount of extensions of credit to
directors, executive officers and Citizens principal shareholders identified
below, and any of their associates (excluding extensions of credit which were
less than $60,000 to any one such person and their associates) were $1,932,000
and $90,000, respectively, which represented approximately 16.8% and 0.8%,
respectively, of total shareholders' equity.





                                       40
   49

         Each non-employee director of The Company and the Bank is paid a $500
fee for each meeting of The Company or the Bank attended and a $100 fee for each
committee meeting attended.

         Mr. Stone entered into an employment agreement with the Bank on
December 16, 1986 which is terminable by the Bank at its discretion. The
agreement provides, among other things, for a base salary which is determined
annually by the Bank's executive compensation committee. Currently, Mr. Stone's
base salary is $143,530. In the event Mr. Stone is terminated "without cause",
he is entitled to receive severance pay in an amount equal to two times the
highest rate of compensation paid to him during the term of his employment
agreement. If, however, Mr. Stone's employment is terminated "without cause" or
is voluntarily terminated by him following any buyout, takeover, merger,
acquisition, or reorganization of the Bank, then Mr. Stone is entitled to three
times such highest compensation amount.

         Messrs. Stone and Carley each entered into a Non-Qualified Deferred
Compensation Agreement with the Bank on August 1, 1996 whereby certain
retirement payments are to be made to them following their retirement. The
annual retirement payments which are to be paid to Mr. Stone for the 15 year
period following retirement will be equal to 70% of the annual salary paid
immediately prior to his retirement. The receipt of the full value of such
payments are subject to certain vesting requirements, and will not fully vest
until 5 years after the date of the agreement except upon a "Change of Control"
(as defined in the agreement), in which case the benefits vest immediately. Mr.
Carley's agreement is similar except that such retirement benefits have been
determined ($11,826 per month), such payments have commenced, and such payments
will continue for a period of 9 years and 11 months from the date of the
agreement. Mr. Carley's agreement also provides that the Bank shall attempt to
offer Mr. Carley a board of directors position with any successor or acquiring
institution to the extent possible and advisable.

         In connection with the proposed merger of Citizens and the Bank with
and into FNB subsidiaries, David P. Stone, President of Citizens, has entered
into an employment agreement with FNB, contingent upon the consummation of the
merger. Under this employment agreement, Mr. Stone will, among other benefits,
(i) receive a $290,000 bonus upon the consummation of the merger in waiver of
his right under his employment agreement with Citizens to receive the
Termination Bonus, (ii) be employed for a term of two years, which term
automatically renews for successive one year terms unless sooner terminated upon
notice sent at least 90 days in advance of the end of the then current term, and
(iii) receive a base annual salary of $145,000, adjusted from time to time to
reflect merit and an annual cost-of-living increase comparable to similarly
positioned officers of FNB. See "The Merger --Interests of Certain Persons in
the Merger".

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OR
                          PLAN OF OPERATION OF CITIZENS

GENERAL

         Citizens' principal asset is its ownership of the Bank and, as a
result, Citizens' results of operations is primarily dependent on the results of
operations of the Bank. The Bank conducts a general commercial banking business
which consists of attracting deposits from the general public and applying those
funds to the origination of loans for commercial, consumer, and residential
purposes. The Bank's profitability depends primarily on net interest income,
which is the difference between interest income generated from interest-earning
assets (i.e., loans and investments) less the interest expense incurred on
interest-bearing liabilities (i.e., customer deposits and borrowed funds). Net
interest income is affected by the relative amounts of interest-earning assets
and interest-bearing liabilities, and the interest rate paid on these balances.

         Net interest income is dependent upon the Bank's interest rate spread,
which is the difference between the average yield earned on its interest-earning
assets and the average rate paid on its interest-bearing liabilities. When
interest-earning assets approximate or exceed interest-bearing liabilities, any
positive interest rate spread will generate net interest income. During 1997,
the Bank maintained a net yield on average earning assets of 5.25%. The net
yield is impacted by interest rates, deposit flows, and loan demands.

         Additionally, the Bank's profitability also is affected by such factors
as the level of non-interest income and expenses, the provision for loan losses,
and the effective tax rate. Non-interest income consists primarily of service
charges and other fees, rental income, and income from fiduciary activities.
Non-interest expenses primarily consist of compensation and benefits, occupancy
related expenses, and other operating expenses.

         The following discussion and analysis of earnings and related financial
data is presented herein to assist investors in understanding the financial
condition and results of operations of the Bank for the fiscal years ended
December 31, 1997 and 1996, and with respect to the three month period ended
March 31, 1998 compared to the three month period ended March 31, 1997. Results
for the three month period ended March 31, 1998, may not be indicative of the
results for the entire year ending on December 31, 1998. This discussion should
be read in conjunction with the consolidated financial statements and related
footnotes presented elsewhere herein.

RESULTS OF OPERATIONS

         Comparison of the Three Months Ended March 31, 1998 and 1997.

         For the three months ended March 31, 1998, Citizens reported net
earnings of approximately $294,000 or $0.49 basic earnings per share, and $0.47
diluted earnings per share, as compared to net earnings of $257,000 or $0.43
basic earnings per share, and $0.41 diluted earnings per share for the
three-month period ending March 31, 1997, an increase of approximately $37,000.
Net earnings for the three-month period ending March 31, 1998 were approximately
14.4% higher than the three months ended March 31, 1997 due principally to an
increase in net interest income, partially offset by an increase in noninterest
expenses. Net interest income increased to approximately $1,337,000 for the
three months ended March 31, 1998 compared with approximately $1,124,000 for the
three months ended March 31, 1997. A substantial portion of this increase was
attributable to an increase in interest income on the Bank's loan portfolio
volume.

         The Bank's total assets at March 31, 1998 were approximately $121.2
million, an increase of $11.4 million or 10.3%, from March 31, 1997. This
increase was primarily due to an increase in the Bank's loan portfolio partially
offset by a decrease in cash and cash equivalents.



                                       43
   52

         The Bank's loans at March 31, 1998, totalled approximately $72.7
million, net, or approximately 60.0% of total assets. The net loan portfolio
consisted of $17.0 million of commercial loans, $48.6 million of real estate
construction and mortgage loans, and $7.1 million of consumer loans. The
allowance for loan losses has increased from approximately $844,000 at March 31,
1997 to $848,000 at March 31, 1998. The loan loss allowance represents
approximately 1.2% of total loans, down from 1.4% at March 31, 1997.

         Comparison of the Fiscal Years Ended December 31, 1997 and 1996

         For the year ended December 31, 1997, Citizens reported net earnings of
approximately $1,052,000, or $1.74 basic earnings per share, and $1.67 diluted
earnings per share, as compared to net earnings of approximately $379,000 or
$0.63 basic earnings per share, and $0.60 diluted earnings per share, for the
year ended December 31, 1996. The 1997 net earnings compares favorably to net
earnings for the year ended December 31, 1996 due principally to an increase in
net interest income and a decrease in noninterest expenses. Net interest income
for the year ended December 31, 1997 was approximately $4,800,000, or 5.3% of
average earning assets, as compared to $4,582,000 or 5.6% for the year ended
December 31, 1996. The increase in net interest income was primarily due to an
increase in the average loan portfolio balance partially offset by an increase
in the average balance of deposits. The increase in net earnings was partially
offset by an increase in interest expense and income taxes. Additionally, the
Bank's provision for loan losses was $97,000 in 1997 as compared to a negative
provision of $168,000 in 1996. See "Management's Discussion and Analysis of
Financial condition and Results of Operations -- Net Interest Income" and
"--Provisions for Loan Losses."

         Citizens' total assets at December 31, 1997 was approximately $117.0
million, an increase of approximately $16.3 million, or 16.2%, from December 31,
1996. This increase was primarily due to an increase in the Bank's loan
portfolio balance of approximately $14.7 million from December 31, 1996 compared
to the same period ended 1997.

         The Bank's loans at December 31, 1997, totalled approximately $72.4
million, or approximately 61.9% of total assets. As noted above, of the $72.4
million loans, $19.0 million were commercial loans, $46.1 million were real
estate construction and mortgage loans, and $7.3 million were installment loans.
The allowance for loan losses has decreased from $844,000 at December 31, 1996
to $840,000 at December 31, 1997. The loan loss allowance represents
approximately 1.2% of total loans, down from 1.5% at December 31, 1996.
Management believes the current level in the allowance for loan losses is
adequate to absorb potential losses in the loan portfolio. See "Management's
Discussion and Analysis or Plan of Operations of Citizens -- Provisions for Loan
Losses."

NET INTEREST INCOME

         Net interest income, which constitutes the principal source of income
for the Bank, represents the difference between interest income on
interest-earning assets and interest expense on interest-bearing liabilities.
The principal interest-earning assets are loans made to businesses and
individuals. Interest-bearing liabilities primarily consist of time deposits,
interest paying checking accounts (referred to as NOW accounts), retail savings
deposits and money market accounts. Funds attracted by these interest-bearing
liabilities are invested in interest-earning assets. Accordingly, net interest
income depends upon the volume of average interest-earning assets and average
interest-bearing liabilities and the interest rates earned or paid on them.

         Net interest income for the three month periods ended March 31, 1998
and 1997 was approximately $1.3 million and $1.1 million respectively, and the
net yields on average interest-earning assets were 5.31% and 5.19%,
respectively. Net interest income increased primarily due to the increase in the
interest earned on the Bank's loan portfolio which was partially offset by the
increase in the interest on the Bank's deposits.

         Net interest income for the fiscal years ended December 31, 1997 and
1996 totalled approximately $4.8 million and $4.6 million, respectively, and the
net yields on average interest-earning assets were 5.25% and 5.61%,
respectively. Total interest expense for the year ended December 31, 1997 and
1996, was approximately $2.7 million and $2.1 million respectively, and the
average cost of interest bearing liabilities for the respective periods were
3.9% and 3.6%,





                                       44
   53


respectively. The decline in net interest margin was the result of an increase
in the weighted average interest rates on deposit accounts. Management does not
consider the decline to be indicative of any future trend.

         The following table shows for each category of interest-earning assets
and interest-bearing liabilities, the average amount outstanding, the interest
earned or paid on such amount, and the average rate earned or paid for the years
ended December 31, 1997 and 1996. The table also shows the average rate earned
on all interest-earning assets, the average rate paid on all interest-bearing
liabilities, and the net yield on average interest-earning assets for the same
periods.

PROVISION FOR LOAN LOSSES

         Through the three month period ended March 31, 1998, a provision for
loan losses by the Bank was made in the amount of approximately $35,000 as
compared to no provision for the three month period ended March 31, 1997. The
provision (credit) for loan losses was approximately $97,000 and $(168,000) for
the years ended December 31, 1997 and 1996, respectively. The Bank has
determined the appropriation of its loan loss allowance from an analysis of its
actual loss experience applied to its current loan portfolio; management
believes this methodology adequately reflects the risks associated with its loan
portfolio.

         The targeted level of loan loss allowance has been based upon
management's continual review of the loan portfolio. Management reviews the
loans by type and nature of collateral and establishes an appropriate provision
for loan losses based upon historical charge-off experience, the present and
prospective financial condition of specific borrowers, industry concentrations
within the loan portfolio, size of the credit, existence and quality of any
collateral, profitability, and general economic conditions.

         The total allowance for loan losses has decreased from approximately
$844,000 (or 1.5% of total loans) in 1996 to approximately $840,000 (or 1.2% of
total loans) in 1997. The Bank had loans on non-accrual status of $90,078 and
$306,571 as of December 31, 1997 and 1996, respectively.

         Although management uses the best information available to make
determinations with respect to the allowance for loan losses, future adjustments
may be necessary if economic conditions differ substantially from the
assumptions used. Material additions to the Bank's allowance for loan losses
would result in a decrease in

the Bank's net earnings and capital. See "Management's Discussion and Analysis
or Plan of Operations of Citizens Allowance for Loan Losses."

NON-INTEREST INCOME

         For the three months ended March 31, 1998 and 1997, non-interest income
was approximately $365,000 and $330,000, respectively, an increase of
approximately 10.8%. The increase was primarily due to increased revenues from
service charges and fees.

         Non-interest income increased to approximately $1,380,000 for the year
ended December 31, 1997, from $1,131,000 for the same period ended 1996, an
increase of 22.1%. The increase in non-interest income was primarily the result
of an increase in income from fiduciary activities.

         The following table summarizes the major components of non-interest
income for the periods indicated.

NON-INTEREST EXPENSE

         Non-interest expense for the three months ended March 31, 1998 and
1997, totalled approximately $1,223,000 and $1,065,000, respectively. The
increase was due primarily to an increase in advertising and promotion expenses
associated with a new advertising campaign that began in the last quarter of
1997.

         Non-interest expense decreased from approximately $5,348,000 for the
year ended December 31, 1996, to $4,503,000 for the year ended December 31,
1997, due primarily to a decrease in employee compensation and benefits as the
Bank recognized expense of approximately $1.2 million in 1996 for deferred
compensation plans partially offset by an increase in occupancy expense.

         The relationship of non-interest expense to average assets was 4.21%
and 5.64% for 1997 and 1996, respectively.

INCOME TAX EXPENSE

         For the three month period ended March 31, 1998 and 1997, the Bank's
provision for income taxes was approximately $150,000 and $131,000,
respectively. The increase was the result of increased earnings for the three
month period in 1998 as compared to 1997.

         For the year ended December 31, 1997, the Bank's provision for income
taxes was approximately $528,000 as compared to $153,000 for the year ended
December 31, 1996, as a result of increased earnings during 1997. The effective
tax rate was 33.4% and 28.8% for the years ended December 31, 1997 and 1996,
respectively. During 1996, tax-free interest income constituted a larger
percentage of earnings before income taxes, which earnings were lower in 1996
because of higher net expenses associated with deferred compensation agreements
adopted in 1996, thereby resulting in a lower effective tax rate in 1996 than in
1997.

ASSET/LIABILITY MANAGEMENT

         Management seeks to maintain a program of asset and liability
management designed to limit its vulnerability to interest rate risk. The
principal measure of the Bank's exposure to interest rate risk is its interest
rate sensitivity "gap" which is the difference between interest rate sensitive
assets and liabilities. An asset or liability is considered to be interest rate
sensitive if it will reprice or mature within the time period analyzed, usually
one year. A gap is considered positive when the amount of interest rate
sensitive assets exceeds the amount of interest rate sensitive liabilities. When
the opposite occurs, the gap is considered to be negative. During periods of
increasing interest rates, a negative gap would tend to adversely affect net
income while a positive gap would tend to result in an increase in net interest
income. During periods of decreasing interest rates, the inverse would tend to
occur. If the maturities of the Bank's assets and liabilities were equally
flexible and moved concurrently, the impact of any material or prolonged
increase (or decrease) in interest rates or net interest income would be
minimal.

         The Bank's asset and liability policies are directed toward matching,
to the extent possible, its interest rate sensitive assets and liabilities to
achieve and maintain a satisfactory differential between its interest income and
interest expense regardless of the general level and movement of interest rates.
To this end, an Asset and Liability Management Committee ("ALCO Committee")
reviews on a regular basis the duration of asset and liability categories.

         The Bank's cumulative one-year gap at December 31, 1997 was a negative
$19,807,000 (or -17% expressed as a percentage of total assets). The negative
one year gap figure is due significantly to the large amount of NOW accounts
held by the Bank. Despite the negative cumulative one year gap, the Bank has not
experienced any decline in deposit balances due to changes in interest rates.
However, there can be no assurance that any substantial and prolonged increase
in market interest rates would not have an adverse impact on the Bank's results
of operations.

         The following tables set forth the interest rate-sensitive assets and
liabilities of the Bank at December 31, 1997, which are expected to mature or
are subject to repricing in each of the time periods indicated. The tables may
not be indicative of the Bank's rate sensitive position at other points in time.
The balances have been derived based on the financial characteristics of the
various assets and liabilities. Adjustable and floating rate assets are included
in the period in which interest rates are next scheduled to adjust rather than
their scheduled maturity dates. Fixed rate loans are shown in the periods in
which they are scheduled to be repaid. Repricing of time deposits is based on
their scheduled maturities. Deposits without a stated maturity are regarded as
readily accessible withdrawable accounts

LENDING ACTIVITIES

A primary source of income for the Bank is the interest earned on loans. At
December 31, 1997, the Bank's total assets were approximately $117.0 million as
compared to $100.6 million at December 31, 1996, and net loans of $71.6 million
representing 61.2% of the total assets for 1997 as compared to net loans of
$56.9 million representing 56.6% of the total assets in 1996. Management
believes that the increase in net loans from

1996 to 1997 is primarily attributable to
increased loan demand resulting from a stronger local economy as well as its
reputation among business and individuals located in its primary market area as
an independent community bank.

LOAN CLASSIFICATION

         Management has sought to maintain a high quality of assets through
conservative underwriting and sound lending practices. Management has followed
this policy even though it may have caused it to forego the funding of higher
yielding loans. Approximately 61% of the loans at December 31, 1997 in the
Bank's portfolio are collateralized by first mortgage liens on commercial real
estate, and one-to-four-family residences which historically have carried
relatively low credit risk. The level of delinquent loans and foreclosed real
estate as of the period end also is relevant to the credit quality of the loan
portfolio.

         In an effort to maintain the quality of the loan portfolio, management
has sought to minimize higher risk types of lending and additional precautions
have been taken when such loans are made in order to reduce the Bank's risk of
loss. Generally, construction loans present a higher degree of risk to a lender
depending, among other things, whether the borrower has permanent financing in
place at the end of the loan period, whether the project is income producing in
the interim, and the nature of the change in economic conditions, including
changing interest rates. With respect to its real estate related loans, there
can be no assurance that a downturn in the value of the real estate on the
central west coast of Florida will not have a material adverse impact on the



                                       51
   60

profitability of the Bank's loans. However, as part of its loan portfolio
management strategy, the Bank has typically required a substantial percentage of
the purchase price as a down payment, and as collateral for the loan, a first
mortgage interest in the entire property to be encumbered, not just the
proportionate value of the property which relates to the amount loaned.
Management believes that such precautions have reduced the Bank's exposure to
the risks associated with a downturn in real estate values.

         Commercial loans also entail certain additional risks since they
usually involve large loan balances to single borrowers or a related group of
borrowers, resulting in a more concentrated loan portfolio. Further, since their
repayment is usually dependent upon the successful operation of the commercial
enterprise, they also are subject to adverse conditions in the economy.
Commercial loans are generally riskier than residential mortgages because they
are typically made on the basis of the ability to repay from the cash flow of a
business rather than on the ability of the borrower or guarantor to repay.
Further, the collateral underlying commercial loans may depreciate over time,
and occasionally cannot be appraised with as much precision as real estate, and
may fluctuate in value based on the success of the business. Commercial loans on
the central west coast of Florida tend to be sensitive to the fluctuations of
the tourist and construction industries, the mainstays of the local economy.

         While there is no assurance that the Bank will not suffer any losses on
its construction loans or its commercial real estate loans, management believes
that it has reduced the risks associated therewith because, among other things,
substantially all of such loans relate to owner-occupied projects, projects
where the borrower has received permanent financing commitments from which the
Bank will be repaid, and projects where the borrower has demonstrated to
management that its business will generate sufficient income to repay the loan.
In this regard, the Bank has made a few land acquisition and development loans
and construction loans to developers of residential properties for the
construction of real estate subdivisions and multi-family housing projects. The
Bank primarily enters into agreements with individuals who are familiar to the
Bank and are residents of the Bank's primary market area.

         In addition to maintaining high quality assets, management has
attempted to limit the Bank's risk exposure to any one borrower or borrowers
with similar or related entities. As of March 31, 1998, the Bank has extended
credit in excess of $2.0 million to only 6 borrowers. The current outstanding
balance of these 6 credits is approximately $8.9 million. Other commercial banks
have participated in, and are participating in, these loan agreements so that
the Bank would not exceed its legal lending limits in existence at that time. As
of March 31, 1998, all of these loans were performing in accordance with their
contractual terms.

         Loan concentrations are defined as amounts loaned to a number of
borrowers engaged in similar activities which would cause them to be similarly
impacted by economic or other conditions. The Bank, on a routine basis,
evaluates these concentrations for purposes of policing its concentrations and
to make necessary adjustments in its lending practices that most clearly reflect
the economic times, loan to deposit ratios, and industry trends. As of March 31,
1998, total loans to any particular group of customers engaged in similar
activities or having similar economic characteristics did not exceed 10% of
total loans. However, as indicated above, a substantial natural geographical
concentration of credit risk exists within the Bank's primary market area.

         The Board of Directors of the Bank concentrates its efforts and
resources, and that of its senior management and lending officials, on loan
review and underwriting procedures. The Bank utilizes the services of an
independent audit firm to perform periodic loan review procedures. Internal
controls include a loan review specialist employed by the Bank, who performs
on-going reviews of loans made to monitor documentation and ensure the existence
and valuations of collateral. The Bank's Loan Committee reviews monthly all
loans subject



                                       52
   61

to close monitoring due to internal policy guidelines. In addition, senior loan
officers of the Bank have established a review process with the objective of
quickly identifying, evaluating, and initiating necessary corrective action for
marginal loans. The goal of the loan review process is to address watch,
substandard and non-performing loans as early as possible. Combined, these
components are integral elements of the Bank's loan program which has resulted
in its loan portfolio performance to date. Nonetheless, management maintains a
cautious outlook in anticipating the potential effects of uncertain economic
conditions (both locally and nationally) and the possibility of more stringent
regulatory standards.

         Loans, including impaired loans, generally, have been classified by the
Bank as non-accrual if they are past due as to maturity or payment of principal
or interest for a period of more than ninety days, unless such loans are well
collateralized in the process of collection. If a loan or a portion of a loan is
classified as doubtful or is partially charged off, the loan is classified as
non-accrual. Loans that are on a current payment status or past due less than
ninety days may also be classified as non-accrual if repayment in full of
principal and/or interest is in doubt. Loans are not returned to accrual status
until principal and interest payments are brought current and future payments
appear certain.

         Interest accrued and unpaid at the time a loan is placed on non-accrual
status is reversed with a corresponding reduction in interest income. While a
loan is classified as non-accrual and the future collectibility of the recorded
loan balance is doubtful, collections of interest and principal are generally
applied as a reduction to principal outstanding. When the future collectibility
of the recorded loan balance is expected, interest income may be recognized on a
cash basis. In the case that a non-accrual loan had been partially charged off,
recognition of interest on a cash basis is limited to that which would have been
recognized on the recorded loan balance at the contractual interest rate. Cash
interest receipts in excess of that amount are recorded as recoveries to the
allowance for loan losses until prior charge-offs have been fully recovered.

         Real estate acquired by the Bank as a result of foreclosure or
acceptance of deeds in lieu of foreclosure is classified as foreclosed real
estate. These properties are recorded on the date acquired at the lower of fair
value less estimated selling costs or the recorded investment in the related
loan. If the fair value after deducting the estimated selling costs of the
acquired property is less than the recorded investment in the related loan, the
estimated loss is charged to the allowance for loan losses at that time. The
resulting carrying value established at the date of foreclosure becomes the new
cost basis for subsequent accounting. After foreclosure, if the fair value less
estimated selling costs of the property becomes less than its cost, the
deficiency is charged against earnings as a provision for losses on foreclosed
real estate. Costs relating to the developmental improvement of the property are
capitalized, whereas those relating to holding the property for sale are charged
as an expense. At December 31, 1997 and 1996 the Bank had no foreclosed real
estate.

         In addition, the Bank performs ongoing reviews of its new and existing
loans to identify, evaluate, and initiate corrective action for substandard or
doubtful loans. As of March 31, 1998, the Bank has classified approximately 10
loans to 8 borrowers as either substandard or doubtful representing aggregate
borrowings of $461,633.

         The following table sets forth certain information with respect to the
Bank's non-accrual loans and accruing loans which are contractually past due 90
days or more as to principal or interest.

         The total amount of loans over ninety days past due totalled
approximately $0, $0, and $17,121 as of March 31, 1998, December 31, 1997, and
December 31, 1996, respectively. The approximate amount of interest on
non-accrual loans which would have been recorded as income under the original
terms of such loans was $3,056 for the three months ended March 31, 1998, and
$18,364 and $20,988 for the fiscal years ended December 31, 1997 and 1996,
respectively. The amount of interest income collected on non-accrual loans that
was included in net income for the three months ended March 31, 1998 and the
years ended December 31, 1997 and 1996 was approximately $0, $0, and $5,845,
respectively. The amount of interest income accrued on loans contractually past
due ninety days or more at March 31, 1998, and at December 31, 1997 and 1996 was
approximately $0, $0, and $357, respectively.

ALLOWANCE FOR LOAN LOSSES

         In originating loans, the Bank recognizes that loan losses will be
experienced and that the risk of loss will vary with, among other things, the
type of loan being made, the creditworthiness of the borrower over the term of
the loan and, in the case of a collateralized loan, the quality of the
collateral for the loan as well as general economic conditions. It is
management's policy to maintain an adequate allowance for loan losses based on,
among other things, the Bank's historical loan loss experience, evaluation of
economic conditions and regular reviews of delinquencies and loan portfolio
quality.

         The allowance for loan losses has been established through charges to
earnings in the form of a provision for loan losses. Increases and decreased in
the allowance due to changes in the measurement of the impaired loans are
included in the provision for loan losses. Loans continue to be classified as
impaired unless they are brought fully current and the collection of scheduled
interest and principal is considered probable. When a loan or portion of a loan
is determined to be uncollectible, the portion deemed uncollectible is charged
against the allowance.

         Management actively monitors the Bank's asset quality and to charge-off
loans against the allowance for loan losses when appropriate or to provide
specific loss allowances when necessary. Although management believes it uses
the best information available to make determinations with respect to the
allowance for loan losses, future adjustments may be necessary if economic
conditions differ from the economic conditions in the assumptions used in making
the initial determinations.

         The Bank's allowance for loan losses was $848,000 at March 31, 1998
(1.2% of total loans), an increase of $8,000 over the allowance for loan losses
at December 31, 1997. The allowance for loan losses represents 1.2% of portfolio
loans at both March 31, 1998 and December 31, 1997 respectively. The Bank had
$32,000 for loan charge-offs and $5,000 in recoveries on previously charged-off
loans for the three month period ended March 31, 1998 and $120,000 of
charge-offs and $19,000 of recoveries for the fiscal year ended December 31,
1997. Management believes it maintains an adequate allowance for loan losses.

         The following table sets forth an analysis of the Bank's allowance for
possible loan losses for the periods indicated.

allocation of an allowance to each category is not necessarily indicative of
future losses and does not restrict the use of the allowance to absorb losses in
any other category.

DEPOSIT ACTIVITIES AND OTHER SOURCES OF FUNDS

         Deposits are the major source of the Bank's funds for lending and other
investment purposes. In addition to deposits, the Bank derives funds from
interest payments, loan principal payments and funds provided from operations.
Scheduled loan repayments are a relatively stable source of funds, while deposit
inflows are significantly influenced by general interest rates and money market
conditions. The Bank may use borrowings on a short-term basis if necessary to
compensate for reductions in the availability of other sources of funds. They 
also may be used on a longer-term basis for general business purposes.

         DEPOSIT ACTIVITIES. Deposits are attracted principally from within the
Bank's primary market area through the offering of a broad variety of deposit
instruments including checking accounts, money market accounts, regular savings
accounts, term certificate accounts (including "jumbo" certificates in
denominations of $100,000 or more) and retirement savings plans. As of December
31, 1997, jumbo certificates accounted for approximately $6.8 million of the
Bank's deposits. Of this amount, $5.6 million had a term of twelve months or
less. The Bank has not aggressively attempted to obtain large denomination, high
interest-bearing certificates of deposit in the past.

         Maturity terms, service fees and withdrawal penalties are established
by the Bank on a periodic basis. The determination of rates and terms is
predicated on funds acquisition and liquidity requirements, rates paid by
competitors, growth goals and federal regulations.

         Regulations promulgated by the FDIC pursuant to FDICIA place
limitations on the ability of insured depository institutions to accept, renew,
or roll-over deposits by offering rates of interest which are significantly
higher than the prevailing rates of interest on deposits offered by other
insured depository institutions having the same type of charter in such
depository institution's normal market area. Under these regulations, "well
capitalized" depository institutions may accept, renew, or roll such deposits
over without restriction, "adequately capitalized" depository institutions may
accept, renew or roll such deposits over with a waiver from the FDIC (subject to
certain restrictions on payments of rates), and "undercapitalized" depository
institutions may not accept, renew or roll such deposits over. The regulations
contemplate that the definitions of "well capitalized," "adequately capitalized"
and "undercapitalized" will be the same as the definitions adopted by the
agencies to implement the corrective action provisions of the FDICIA. As of
March 31, 1998, the Bank met the definition of a "well capitalized" depository
institution.

         CERTIFICATES OF DEPOSIT. At December 31, 1997, certificates of deposit
represented approximately 28.3% of the Bank's total deposits, as compared to
28.8% of total deposits at December 31, 1996. The Bank does not

have a concentration of deposits from any one source, the loss of which would
have a material adverse effect on the business of The Company. Management
believes that substantially all of the Bank's depositors are residents, either
full or part time, in its primary market area.

         The following table summarizes the amount of the Bank's certificates of
deposit of $100,000 or more by time remaining until maturity at December 31,
1997 and December 31, 1996.

         BORROWINGS. If there are periods when the supply of funds from deposits
cannot meet the demand for loans, the Bank has the ability to seek a portion of
the needed funds through loans (advances) from the FHLB of Atlanta where the
Bank currently has a $13 million line of credit. As of December 31, 1997, no
amount was borrowed on the line.

         The Bank has entered into repurchase agreements with certain customers,
whereby the Bank has agreed to sell certain securities held in its investment
portfolio in return for a simultaneous commitment by the customer to resell the
securities back to the Bank. In effect, the Bank's customer purchases eligible
securities from the Bank for a specified period of time and agrees to sell those
securities back to the Bank upon maturity of the transactions. The customers
earn a specific rate of interest rate, payable daily for the duration of the
transaction, that bears no relation to the interest rate of the underlying
security. Amounts outstanding at December 31, 1997 and 1996 under these
repurchase agreements were $3,434,034 and $1,845,921, respectively. The Bank has
secured the repurchase agreements by pledging securities from its investment
portfolio in an equivalent amount.

LIQUIDITY AND CAPITAL RESOURCES

         Liquidity is defined as the ability of Citizens and the Bank to
generate sufficient cash to fund current loan demand, deposit withdrawals, other
cash demands and disbursement needs, and otherwise to operate on an ongoing
basis. The Bank's principal sources of funds are deposits, principal and
interest payments on loans and investments, and capital contributions from
Citizens. During 1997, the Bank received $13.5 million from net deposit growth,
and $7.1 million from repayments and maturing investments. In addition, the Bank
also has the ability to borrow from the FHLB to supplement its liquidity needs.
At December 31, 1997, the Bank had no outstanding borrowings from the FHLB.

         At December 31, 1997, shareholders' equity was approximately $11.8
million, or 10.1% of total assets, as compared to $10.7 million at December 31,
1996, or 10.6% of total assets. At December 31, 1997 and December 31, 1996,
respectively, Citizens' Tier I leverage ratio was 10.96% and 11.27%, the Tier I
risk-based capital ratio was 13.82% and 15.27% and the total risk-based capital
ratio was 14.76% and 16.49%, all in excess of FDIC guidelines for a "well
capitalized" bank.

         At December 31, 1997 and December 31, 1996, the liquidity ratio of
Citizens was 32.3% and 37.7%, respectively, well in excess of regulatory
requirements.

         Management believes that there are adequate funding sources to meet its
future liquidity needs for the foreseeable future. Primary among these funding
sources are the repayment of principal and interest on loans, the renewal of
time deposits, and the growth in the deposit base. Management does not believe
that the terms and conditions that will be present at the renewal of these
funding sources will significantly impact Citizens' operations, due to its
management of the maturities of its assets and liabilities.

IMPACT OF INFLATION AND CHANGING PRICES

         The financial statements and related financial data concerning Citizens
presented in this Proxy Statement-Prospectus have been prepared in accordance
with generally accepted accounting principles, which require the measurement of
financial position and operating results in terms of historical dollars without
considering changes in the relative purchasing power of money over time due to
inflation. The primary impact of inflation on the operations of Citizens is
reflected in increased operating costs. Unlike most industrial companies,
virtually all of the assets and liabilities of a financial institution are
monetary in nature. As a result, changes in interest rates have a more
significant impact on the performance of a financial institution than do the
effects of changes in the general rate of inflation and changes in prices.
Interest rates do not necessarily move in the same direction or in the same
magnitude as the prices of goods and services.

YEAR 2000

         Almost all of Citizens' operations are supported by accounting and
record keeping computerized systems and are dependent on the capability of
software applications and operating systems to function properly in the year
2000. Citizens has an ongoing program designed to ensure that its operational
and financial systems will not be adversely affected by year 2000 software
failures, due to processing errors arising from calculations using the year 2000
date. Based on current estimates, Citizens expects to incur expenses of $50,000
over the next two years on its program to redevelop, replace, or repair its
computer applications to make them "Year 2000 compliant." While Citizens
believes it is doing everything technologically possible to assure Year 2000
compliance, it is to some extent dependent upon vendor cooperation. Citizens is
requiring its computer system and software vendors to represent that the
products provided are, or will be, Year 2000 compliant, and has planned a
program of testing for compliance. While Citizens believes that all essential
computer applications will be Year 2000 compliant and that the costs associated
with Year 2000 compliance will not be material to Citizens, any Year 2000
compliance failure could result in additional expense to Citizens.

           DESCRIPTION OF FNB CAPITAL STOCK AND CITIZENS CAPITAL STOCK

FNB COMMON STOCK

         GENERAL. FNB is authorized to issue 100,000,000 shares of FNB Common
Stock, of which 16,904,785 shares (adjusted for 5% stock dividend) were
outstanding as of June 30, 1998. FNB Common Stock is traded on the Nasdaq
National Market under the trading symbol "FBAN." FNB provides transfer agent and
registrar services for FNB Common Stock.

         As of June 30, 1998, 2,959,947 shares of FNB Common Stock were reserved
for issuance under various employee benefit plans, and the voluntary dividend
reinvestment plan of FNB. After taking into account the shares reserved as
described above, the number of authorized shares of FNB Common Stock available
for other corporate purposes as of June 30, 1998 was 80,135,268. Since that
date, 1,407,733 additional shares have been reserved for issuance in connection
with the merger.

         VOTING AND OTHER RIGHTS. The holders of FNB Common Stock are entitled
to one vote per share, and, in general, a majority of votes cast with respect to
a matter is sufficient to authorize action upon routine matters. Directors are
elected by a plurality of the votes cast, and each shareholder entitled to vote
in such election is entitled to vote each share of stock for as many persons as
there are directors to be elected. In elections for directors, shareholders do
not have the right to cumulate their votes. The FNB Series A Preferred Stock (as
defined herein) votes as a class with the FNB Common Stock. See "-- FNB
Preferred Stock"; "COMPARISON OF SHAREHOLDER RIGHTS -- Amendment of Articles of
Incorporation and Bylaws" and "-- Vote Required for Extraordinary Corporate
Transaction."

         In the event of liquidation, holders of FNB Common Stock would be
entitled to receive pro rata any assets legally available for distribution to
shareholders with respect to shares held by them, subject to any prior rights of
any FNB Preferred Stock (as defined and described below) then outstanding.

         FNB Common Stock does not have any preemptive rights, redemption
privileges, sinking fund privileges or conversion rights. All the outstanding
shares of FNB Common Stock are, and upon issuance the shares of FNB Common Stock
to be issued to shareholders of Citizens will be, validly issued, fully paid and
nonassessable.

         DISTRIBUTIONS. The holders of FNB Common Stock are entitled to receive
such dividends or distributions as the FNB Board may declare out of funds
legally available for such payments. The payment of distributions by FNB is
subject to the restrictions of Pennsylvania law applicable to the declaration of
distributions by a business corporation. A corporation generally may not
authorize and make distributions if, after giving effect thereto, it would be
unable to meet its debts as they become due in the usual course of business or
if the corporation's total assets would be less than the sum of its total
liabilities plus the amount that would be needed, if it were to be dissolved at
the time of distribution, to satisfy claims upon dissolution of shareholders who
have preferential rights superior to the rights of the holders of its common
stock. In addition, the payment of distributions to shareholders is subject to
any prior rights of outstanding FNB Preferred Stock. Share dividends, if any are
declared, may be paid from authorized but unissued shares.

         The ability of FNB to pay distributions is affected by the ability of
its subsidiaries to pay dividends. The ability of FNB's subsidiaries, as well as
of FNB, to pay dividends in the future is influenced by bank regulatory
requirements and capital guidelines.

FNB PREFERRED STOCK

         GENERAL. FNB has authorized 20,000,000 shares of preferred stock,
$10.00 par value (the "FNB Preferred Stock"). The FNB Board has the authority to
issue FNB Preferred Stock in one or more series and to fix the dividend rights,
dividend rate, liquidation preference, conversion rights, voting rights, rights
and terms of redemption (including sinking fund provisions), and the number of
shares constituting any such series, without any further action by the
shareholders unless such action is required by applicable rules or regulations
or by the terms of other outstanding series of FNB Preferred Stock. Any shares
of FNB Preferred Stock which may be issued may rank prior to shares of FNB
Common Stock as to payment of dividends and upon liquidation. FNB had 20,768
shares of FNB Series A Preferred Stock (the "FNB Series A Preferred Stock")
issued and outstanding as of June 30, 1998 and 251,149 shares of FNB Series B 7
1/2% Cumulative Convertible Preferred Stock (the "FNB Series B Preferred Stock")
issued and outstanding as of June 30, 1998.

         THE FOLLOWING SUMMARY OF THE FNB SERIES A PREFERRED STOCK AND FNB
SERIES B PREFERRED STOCK IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
DESCRIPTION THEREOF CONTAINED IN THE FNB CHARTER ATTACHED AS EXHIBIT 3.1 TO THE
CORPORATION'S ANNUAL REPORT ON FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 1996,
WHICH IS INCORPORATED HEREIN BY REFERENCE.

         FNB SERIES A PREFERRED STOCK. The FNB Series A Preferred Stock was
created for the purpose of acquiring Reeves Bank. Holders of the FNB Series A
Preferred Stock are entitled to 5.1 votes for each share held (as adjusted for
the FNB Stock Dividend). The holders of the FNB Series A Preferred Stock do not
have cumulative voting rights in the election of directors. Dividends on the FNB
Series A Preferred Stock are cumulative from the date of issue and are payable
at a rate of $.42 per share each quarter. The FNB Series A Preferred Stock is
convertible at the option of the holder into shares of the FNB Common Stock
having a market value of $25.00 at time of conversion. FNB has the right to
require the conversion of the balance of all outstanding shares at the
conversion rate at any time after 50% of the 49,512 shares issued are no longer
outstanding. Through June 30, 1998, 550 shares of the FNB Series A Preferred
Stock were converted to 369 shares of FNB Common Stock. At June 30, 1998, 15,202
shares of FNB Common Stock were reserved by FNB for the conversion of the
remaining 20,768 outstanding shares.

         FNB SERIES B PREFERRED STOCK. The FNB Series B Preferred Stock was
issued during 1992 for the purpose of raising capital for the acquisition of 13
banking branches in the Erie, Pennsylvania area. Holders of the FNB Series B
Preferred Stock have no voting rights. Dividends on the FNB Series B Preferred
Stock are cumulative from the date of issue and are payable at a rate of $.46875
per share each quarter. The FNB Series B Preferred Stock has a stated value of
$25.00 per share and is convertible at the option of the holder at any time into
shares of FNB Common Stock at a price of $11.09 per share. FNB has the right to
redeem the FNB Series B Preferred Stock for cash on or after May 15, 1996, as
set forth in the prospectus dated May 8, 1992. Through June 30, 1998, 15,033
shares of FNB Series B Preferred Stock were converted to 32,480 shares of FNB
Common Stock. At June 30, 1998, 566,324 shares of FNB Common Stock were reserved
by FNB for the conversion of the remaining 251,149 outstanding shares of FNB
Series B Preferred Stock.

CITIZENS COMMON SHARES

         GENERAL. Citizens is authorized to issue 2,000,000 Citizens Common
Shares $.10 par value, of which [580,795] shares were issued and outstanding as
of the Record Date. There is no established public trading market for the
Citizens Common Shares. Registrar and Transfer Company, New Jersey acts as the
transfer agent and the registrar for the Citizens Common Shares.

CITIZENS PREFERRED STOCK

         Citizens is authorized to issue 2,000,000 shares of preferred stock,
$0.10 par value ("Citizens Preferred Stock"), none of which are issued and
outstanding. The Citizens Board has the authority to issue Citizens Preferred
Stock in one or more series and to fix the dividend rights, dividend rate,
liquidation preference, conversion rights, voting rights, rights and terms of
redemption (including sinking fund provisions), redemption price or prices, and
the number of shares constituting any such series, without any further action by
the shareholders unless such action is required by applicable rules or
regulations or by the terms of other outstanding series of Citizens Preferred
Stock. Any shares of Citizens Preferred Stock which may be issued may rank prior
to shares of Citizens Common Shares as to payment of dividends and upon
liquidation.

                        COMPARISON OF SHAREHOLDER RIGHTS

         At the Effective Time, the shareholders of Citizens, a Florida
corporation, will become shareholders of FNB, a Pennsylvania corporation, and
Pennsylvania law will govern shareholder rights after the merger. Differences
between the FBCA and the Pennsylvania Business Corporation Law ("PBCL") and
between the Citizens Charter and the Citizens Bylaws and the FNB Charter and the
FNB Bylaws will result in various changes in the rights of shareholders of
Citizens.

         The following is a summary of all material differences between the
rights of FNB shareholders under Pennsylvania law, the FNB Charter and the FNB
Bylaws, as compared with those of Citizens shareholders under Florida law, the
Citizens Charter and the Citizens Bylaws. This summary does not purport to be a
complete description of the provisions discussed and is qualified in its
entirety by the PBCL, the FBCA, the Citizens Charter, the Citizens Bylaws, the
FNB Charter and the FNB Bylaws, to which Citizens shareholders are referred.

REMOVAL OF DIRECTORS; FILLING VACANCIES ON THE BOARD OF DIRECTORS

         Under the PBCL, an FNB director may be removed without cause by the FNB
shareholders entitled to elect the director or by the class of directors in
which such director had been chosen. The FNB Charter contains a provision that
requires the affirmative vote of at least 75% of the outstanding shares of FNB
Common Stock entitled to vote to remove the entire FNB Board, a class of
directors, or any member of the FNB Board during his term without cause.

         The PBCL and the FNB Bylaws provide that vacancies on the FNB Board,
including vacancies resulting from an increase in the number of directors, may
be filled by a majority vote of the remaining directors, though less than a
quorum, or by a sole remaining director, and each person so selected shall serve
until the next selection of the class for which such director has been chosen,
and until a successor has been selected and qualified.




                                       63
   72



         Under the FBCA, unless the Citizens Charter provides that directors may
be removed only for cause, a Citizens director may be removed by the Citizens
shareholders with or without cause; provided that, if a director is elected by a
voting group, only the shareholders of that voting group may participate in the
vote to remove him. The Citizens Charter, however, does include a provision
which provides the director may not be removed except for cause. The FBCA and
the Citizens Bylaws provide that vacancies on the Citizens Board, including
vacancies resulting from an increase in the number of directors and resulting
from removal from office, may be filled by a majority vote of the remaining
directors, though less than a quorum, or by the shareholders at any meeting held
during the existence of such vacancy. A director elected to fill a vacancy shall
have the same remaining term as that of his or her predecessor in office.


QUORUM OF SHAREHOLDERS

         The PBCL and the FNB Bylaws provide that a quorum for a meeting of
shareholders of FNB consists of the presence of shareholders, in person or
represented by proxy, entitled to cast at least a majority of the votes that all
shareholders are entitled to cast on a particular matter to be acted upon at the
meeting.

         Unless the Citizens Charter provide for a greater or a lesser quorum
requirement for shareholders, the FBCA and the Citizens Bylaws provide that the
holders of the majority of votes entitled to be cast on the matter to be
considered, represented in person or by proxy, constitutes a quorum of that
voting group for action on that matter. The FBCA further provides that in no
event shall a quorum consist of less than one-third of the shares entitled to
vote.

ADJOURNMENT AND NOTICE OF SHAREHOLDER MEETINGS

         The FNB Bylaws provide that, if a quorum is not present or represented
at a shareholder meeting, the shareholders entitled to vote may adjourn the
meeting without notice other than an announcement at the meeting. The Citizens
Bylaws also provide that whenever a meeting is adjourned to another time or
place, it shall not be necessary to give any notice of the adjourned meeting as
long as notice of the time and place of the next meeting is made at the
adjourned meeting. Both the FNB and Citizens Bylaws further provide that the
determination of shareholders of record entitled to notice of or to vote at any
meeting of shareholders will apply to any adjournment thereof, unless, in the
case of Citizens, such a meeting is adjourned to a date more than 120 days after
the date fixed for the original meeting (in which case a new record date must be
set).

         Under the PBCL and the FNB Bylaws, notice of shareholder meetings must
be given at least ten days prior to any meeting called to consider a fundamental
corporate change or at least five days prior to the meeting in any other case.
Under the FBCA and the Citizens Bylaws, notice of shareholder meetings must be
provided to each shareholder of record entitled to vote at such meeting not less
than ten nor more than 60 days prior to the meeting.

CALL OF SPECIAL SHAREHOLDER MEETINGS

         The FNB Bylaws provide that special meetings of the shareholders may be
called only by the Chairman of the Board, the President or the Secretary of FNB
pursuant to a resolution or at the written direction of at least 75% of the
members of the FNB Board. The Citizens Charter provides that special meetings of
the shareholders may be called by the Citizens Board or by the holders of 50% of
the votes entitled to be cast on any issue to be considered at the special
meeting of shareholders.




                                       64
   73


SHAREHOLDER CONSENT IN LIEU OF MEETING

         The PBCL permits any action which may be taken at a meeting of the
shareholders may be taken without a meeting, if, prior or subsequent to the
action, a consent thereto of all the shareholders who would be entitled to vote
at a meeting for such purpose is filed with the Secretary of FNB.

         The Citizens Charter provides that any action required or permitted to
be taken by shareholders of Citizens must be effected at a duly called annual or
special meeting of such holders and may not be effected by written consent.

DISSENTERS' RIGHTS

         Under the PBCL, shareholders may perfect dissenters' rights with regard
to corporate actions involving certain mergers; consolidations; sale, lease or
exchange of substantially all the assets of the corporation (under limited
circumstances); or elimination of cumulative voting.

         Under the FBCA, dissenters' appraisal rights are available in
connection with corporate actions involving certain mergers, share exchanges,
consolidations, sales or other dispositions of all or substantially all of the
property of the corporation (other than in the ordinary course of business), the
approval of certain control-share acquisitions, and amendments of the articles
of incorporation where such amendment would adversely affect the shareholder by:
(i) altering or abolishing any preemptive rights attached to such shareholder's
shares; (ii) altering or abolishing the voting rights pertaining to such
shareholder's shares, except as such rights may be affected by the voting rights
of new shares then being authorized of any existing or new class or series of
shares; (iii) effecting an exchange, cancellation, or reclassification of any of
such shareholder's shares, when such amendment would alter or abolish the
shareholder's voting rights or alter his or her percentage of equity in the
corporation, or effecting a reduction or cancellation of accrued dividends or
other arrearages; (iv) reducing the stated redemption price of any of the
shareholder's redeemable shares, altering or abolishing any provision relating
to any sinking fund for the redemption or purchase of any of his or her shares,
or making any of the shareholder's shares subject to redemption when they are
not otherwise redeemable; (v) making non-cumulative, in whole or in part,
dividends on any of his or her preferred shares which had theretofore been
cumulative; (vi) reducing the dividend preference of any of his or her preferred
shares; or (vii) reducing any stated preferential amount payable on the
shareholder's preferred shares upon voluntary or involuntary liquidation.

         Under the corporate laws of Florida and Pennsylvania, dissenters'
rights generally are denied in the case of a merger or share exchange or a
proposed sale or exchange of property when a corporation's shares are listed on
a national securities exchange or the Nasdaq National Market or held of record
by at least 2,000 persons. Consequently, because FNB Common Stock is included in
the Nasdaq National Market, upon becoming a shareholder of FNB, former Citizens
shareholders will no longer have dissenters' rights.

DERIVATIVE ACTIONS

         Derivative actions to enforce a secondary right against any present or
former officer or director of the corporation because the corporation refuses to
enforce rights that may properly be asserted by it may be brought under the PBCL
by a shareholder, even if the shareholder was not a shareholder at the time of
the alleged wrongdoing, if there is a strong prima facie case in favor of the
claim asserted and if the court determines in its discretion that serious
injustice will result without such action.


                                       65
   74


         Under the FBCA, a derivative action may be brought only by a person who
was a shareholder of the corporation at the time of the alleged wrongdoing
unless the person became a shareholder through transfer by operation of law from
one who was a shareholder at that time.

DIVIDENDS AND DISTRIBUTIONS

         Subject to any restrictions in a corporation's charter, the PBCL and
the FBCA generally provide that a corporation may make distributions to its
shareholders unless after giving effect thereto (1) the corporation would not be
able to pay its debts as they become due in the usual course of business, or (2)
the corporation's total assets would be less than the sum of its total
liabilities plus the amount that would be needed upon the dissolution of the
corporation to satisfy the preferential rights of shareholders having superior
preferential rights to those shareholders receiving the distribution. The FNB
Charter does not contain any restrictions on the payment of dividends or the
making of distributions to shareholders.

DIRECTOR QUALIFICATIONS, NUMBER AND TERM

         The articles of incorporation or bylaws of a Pennsylvania corporation
specify the number of directors. If not otherwise fixed, a Pennsylvania
corporation shall have three directors. The PBCL and the FNB Bylaws provide that
the directors need not be state residents or shareholders of the corporation to
qualify to serve.

         The FNB Bylaws also provide that the FNB Board shall consist of such
number of directors as may be determined by the FNB Board, which number shall be
not less than five nor more than 25. By resolution, the FNB Board has set the
present size of the FNB Board at 22 directors. The FNB Bylaws further provide
that the FNB Board shall be divided into four classes, with each director having
a staggered, four-year term.

         The board of directors of a Florida corporation must consist of one or
more individuals, the precise number to be specified or fixed in accordance with
the articles of incorporation or bylaws. Under the FBCA, directors must be at
least 18 years of age but need not be shareholders of the corporation or
residents of Florida to qualify to serve on the board. The Citizens Charter
provides that the initial Citizens Board consists of 11 persons, which number of
directors may be changed from time to time by resolution of the Citizens Board
or by action of the shareholders. By resolution, the Citizens Board has set the
present size at 10 directors. The Citizens shareholders are entitled to elect
all of the members of the Citizens Board. The Citizens Charter also provides
that the Citizens Board shall be divided into three classes, with each director
having a staggered, three-year term.

         After the merger, all members of the Citizens Board will be elected
members of the board of directors of First National Bank of Florida, one of
Southwest's subsidiary banks for a term of one year.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

         The PBCL permits a corporation to indemnify its directors and officers
against expenses, judgments, fines and amounts paid in settlement incurred by
them in connection with any pending, threatened or completed action or
proceeding, and permits such indemnification against expenses incurred in
connection with any pending, threatened or completed derivative action, if the
director or officer has 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,
with respect to any criminal proceeding, had no reasonable cause to believe his
or her conduct was unlawful. Furthermore, Pennsylvania law provides that
expenses incurred in defending any action or proceeding may be paid by the
corporation in advance of the final disposition upon receipt of an undertaking
by or on behalf of the


                                       66

   75


director or officer to repay the amount if it is ultimately determined that the
director or officer is not entitled to be indemnified by the corporation.

         In Pennsylvania, the statutory provisions for indemnification and
advancement of expenses are non-exclusive with respect to any other rights, such
as contractual rights (or under a bylaw or vote of shareholders or disinterested
directors), to which a person seeking indemnification or advancement of expenses
may be entitled. Such contractual or other rights may, for example, provide for
indemnification against judgments, fines and amounts paid in settlement incurred
by the indemnified person in connection with derivative actions. The PBCL
permits such derivative action indemnification in any case except 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.

         The PBCL permits a corporation to purchase and maintain insurance on
behalf of any director or officer of the corporation against any liability
asserted against the director or officer and incurred in such capacity, whether
or not the corporation would have the power to indemnify the director or officer
against such liability. FNB has directors' and officers' liability insurance
underwritten by Reliance Insurance Company.

         The FNB Charter and the Citizens Charter provide that their directors,
officers and any other person designated by the respective Board are entitled to
be indemnified to the fullest extent now permitted by law.

         The FBCA permits a corporation to indemnify a director and officer who
was or is a party to any threatened, pending or completed action, suit or other
type of proceeding, whether civil, criminal, administrative or investigative,
whether formal or informal (other than an action by or any right of the
corporation) by reason of the fact that he or she is or was a director or
officer or is now serving at the request of the corporation as a director or
officer of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines,
penalties and amounts paid in settlement actually and reasonably incurred by him
in connection with such action, suit or proceeding. These indemnification rights
apply if the director or officer acted in good faith and in a manner in which he
or she reasonably believed to be in or not opposed to the best interest of the
corporation and, with respect to criminal action or proceeding, had no
reasonable cause to believe his or her conduct was unlawful. In addition, under
the FBCA, Citizens may indemnify and hold harmless an officer or director who is
a party in an action by or in the right of the corporation against expenses
(including attorneys' fees) and amounts paid in settlement not exceeding
estimated expenses of litigating the action to conclusion, actually and
reasonably incurred in connection with the defense or settlement of such
proceeding, including any appeal thereof. Such indemnification shall be
authorized if the director or officer has acted in good faith and in a manner in
which he or she reasonably believed to be in or not opposed to the best interest
of the corporation, except indemnification is not authorized where there is an
adjudication of liability, unless the court in which such proceeding was
brought, or any other court of competent jurisdiction, shall determine, in view
of all the circumstances, that such person is fairly and reasonably entitled to
indemnity for such expenses which such court shall deem proper.

         The FBCA provides that indemnification of the costs and expenses of
defending any action is required to be made to any officer or director who is
successful (on the merits or otherwise) in defending an action of the type
referred to in the immediately preceding paragraph. Except with regard to the
costs and expenses of successfully defending an action as may be ordered by a
court, indemnification as described in the previous paragraph is only required
to be made to a director or officer if a determination is made that
indemnification is proper under the circumstances. Such determination shall be
made: (i) by the Citizens Board by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding; (ii) by a
majority vote of a committee duly designated by the Citizens Board consisting of
two or more directors not at the time parties to the action, suit or proceeding;
(iii) by independent legal counsel selected by specified groupings of the

Citizens Board; or (iv) by the Citizens shareholders by a majority vote of a
quorum consisting of shareholders who were not parties to such action, suit or
proceeding, or, if no such quorum is obtainable, by a majority vote of
shareholders who were not parties to such action, suit or proceeding. The
reasonableness of the expenses to be indemnified is determined in the same
manner as the determination of whether the indemnification is permissible. The
FBCA further provides that expenses incurred in defending any action or
proceeding may be paid by the corporation in advance of the final disposition
upon receipt of an undertaking by or on behalf of the director or officer to
repay the amount if it is ultimately determined that the director or officer is
not entitled to be indemnified by the corporation.

         Under the FBCA, the provisions for indemnification and advancement of
expenses are not exclusive. Accordingly, a corporation may make any other or
further indemnification or advancement of expenses of any of its officers or
directors under any bylaw, agreement, vote of shareholders or disinterested
directors, or otherwise, both as to action in his or her official capacity and
as to action in another capacity while holding such office. Under the FBCA,
indemnification or advancement of expenses, however, 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 were material to the cause of
action so adjudicated and constitute: (i) a violation of the criminal law,
unless the officer or director had reasonable cause to believe that his or her
conduct was lawful or had no reasonable cause to believe that his or her conduct
was unlawful; (ii) a transaction from which the officer or director derived an
improper personal benefit; (iii) in the case of a director, a circumstance under
which the liability provisions of the FBCA Section 607.0834 (relating to
unlawful distributions) are applicable; or (iv) willful misconduct or a
conscious disregard for the best interest 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.

         Florida law and the Citizens Bylaws permit a corporation to purchase
and maintain insurance on behalf of any director or officer of the corporation
against any liability asserted against the director or officer and incurred in
such capacity, whether or not the corporation would have the power to indemnify
the director or officer against such liability.

DIRECTOR LIABILITY

         The bylaws of a Pennsylvania corporation may include a provision
limiting the personal liability of directors for monetary damages for actions
taken as a director, except to the extent that the director has breached or
failed to perform his or her duties to the corporation and the breach or failure
to perform constitutes self-dealing, willful misconduct, or recklessness. The
FNB Bylaws contain such a provision limiting the liability of its directors to
the fullest extent permitted by law.

         Under Florida law, a director is not liable for monetary damages for
any statement, vote, decision, or failure to act, regarding corporate management
or policy, unless the director breached or failed to perform his duties as a
director and the director's breach of, or failure to perform, those duties
constitutes a violation of criminal law, self dealing, willful misconduct, or
recklessness.

AMENDMENT OF ARTICLES OF INCORPORATION AND BYLAWS

         The PBCL requires the affirmative vote of the holders entitled to cast
at least a majority of the votes actually cast on an amendment to the articles
of incorporation, provided that shareholder approval is not required for certain
non-material amendments, such as a change in the corporate name, a provision for
perpetual existence, or, if the corporation has only one class of shares
outstanding, a change in the number and par value of the authorized shares to
effect a stock split. The FNB Charter provides that the FNB Charter may be
amended by 


                                       68
   77


FNB as provided by the PBCL and all rights conferred upon the shareholders
therein are granted subject to such reservation. Under the PBCL, the power to
adopt, amend or repeal bylaws may be vested by the bylaws in the directors, with
certain statutory exceptions for certain actions and subject to the power of
shareholders to change such action. The PBCL provides that, unless the articles
of incorporation otherwise provide, the board of directors does not have the
authority to adopt or change a bylaw on any subject that is committed expressly
to the shareholders by statute. The FNB Charter and the FNB Bylaws provide that
the FNB Bylaws may be amended by the affirmative vote of at least 75% of the FNB
Board or by the affirmative vote of the holders of at least 75% of the
outstanding FNB Common Stock entitled to vote thereon.

         In order to amend the articles of incorporation of a Florida
corporation, the FBCA generally requires that, unless the articles of
incorporation provide for a greater vote, the votes cast in favor of such an
amendment must exceed the votes cast against such an amendment at a meeting that
at least a quorum is present; provided, however, that a majority of the
outstanding votes entitled to be cast on the amendment is required with respect
to the amendments that would create dissenter's rights under Florida law.
Further, under Florida law shareholder approval is not required for certain
non-material amendments. The Citizens Charter provides that Articles VII
(staggered board), Article XII (prohibition of action by shareholders by written
consent), and Article XIII (super majority voting requirement for certain
business combinations) may not be amended by the affirmative vote of no less
than 67% of the outstanding Citizens Common Shares. See "Comparison of
Shareholders Rights Extraordinary Corporation Transactions."

         Under Florida law, a corporation's bylaws may be amended or repealed by
the board of directors or shareholders; provided, however, that the board may
not amend or repeal the corporation's bylaws if the articles of incorporation
reserve such power to the shareholders, or the shareholders, in amending or
appealing the bylaws, expressly provide that the board of directors may not
amend or repeal the bylaws or a particular bylaw provision. The Citizens Bylaws
provide that the Citizens Bylaws may be altered or amended and new bylaws
adopted by the shareholders or by the Citizens Board. Further, Bylaws adopted by
the Citizens Board may be repealed or amended and new Bylaws may be adopted by
Citizens shareholders. Citizens shareholders may also prescribe in any Bylaw
made by them that such Bylaw not be altered, amended or repealed by the Citizens
Board.

VOTE REQUIRED FOR EXTRAORDINARY CORPORATE TRANSACTIONS

         Under the PBCL, generally, a merger, consolidation, share exchange,
dissolution or sale of substantially all of a corporation's assets other than in
the ordinary course of business must be approved by the affirmative vote of a
majority of the votes cast by all shareholders entitled to vote thereon. Except
as otherwise provided by the bylaws of a corporation, the shareholders of a
corporation do not have to approve a board of directors-approved plan of merger
if, among other situations, (i) the surviving or new corporation is a domestic
business corporation with articles of incorporation that are identical to the
articles of incorporation of the constituent corporation (except for changes
permitted by a board of directors without shareholder approval under the PBCL),
(ii) each share of the constituent corporation outstanding immediately prior to
the effective date of the merger is to continue to be or to be converted into an
identical share of the surviving or new corporation after the effective date of
the merger, and (iii) the shareholders of the constituent corporation are to
hold in the aggregate shares of the surviving or new corporation to be
outstanding immediately after effectiveness of the plan of merger entitled to
cast at least a majority of the votes entitled to be cast generally for the
election of directors.

         The FNB Charter requires the affirmative vote of at least 75% of the
outstanding shares of FNB Common Stock entitled to vote to approve a merger,
consolidation, or sale, lease, exchange or other disposition, in a single
transaction or series of related transactions, of all or substantially all or a
substantial part of the


                                       69
   78


properties or assets of FNB, unless the FNB Board has approved and recommended
the transaction prior to the consummation thereof.

         The Citizen Charter provides that the approval of any proposal for
Citizens to reorganize, merge, or consolidate with another corporation, or sell,
lease or exchange substantially all of its assets or business requires the
affirmative vote of not less than 67% of the outstanding Citizens Common Shares.

INTERESTED SHAREHOLDER TRANSACTIONS

         The PBCL provides that, if a shareholder of a corporation is a party to
a sale of assets transaction, share exchange, merger or consolidation involving
the corporation or a subsidiary, or if a shareholder is to be treated
differently in a corporate dissolution from other shareholders of the same
class, then approval must be obtained of the shareholders entitled to cast at
least a majority of the votes which all shareholders other than the interested
shareholder are entitled to cast with respect to the transaction, without
counting the votes of the interested shareholder. Such additional shareholder
approval is not required if the consideration to be received by the other
shareholders in such transaction for shares of any class is not less than the
highest amount paid by the interested shareholder in acquiring shares of the
same class, or if the proposed transaction is approved by a majority of the
board of directors other than certain directors ("disqualified directors")
affiliated or associated with, or nominated by, the interested shareholder. The
PBCL provides that a director who has held office for at least 24 months prior
to the date of vote on the proposed transaction is not a disqualified director.

         Further, the PBCL prohibits certain business combinations between the
corporation and an interested shareholder except under specified circumstances.
An "interested shareholder" in this instance is one who, directly or indirectly,
is the beneficial owner of shares entitling that person to cast at least 20% of
the votes that all shareholders would be entitled to cast in an election of
directors of the corporation or is an affiliate or associate of such corporation
and at any time within the five-year period immediately prior to the date in
question was the beneficial owner, directly or indirectly, of shares entitling
that person to cast at least 20% of the votes that all shareholders would be
entitled to cast in an election of directors of the corporation. A "business
combination" includes a merger, consolidation, share exchange or division of the
corporation or any subsidiary of the corporation with the interested shareholder
or with, involving or resulting in any other corporation which is, or, after the
merger, consolidation, share exchange or division would be, an affiliate or
associate of the interested shareholder. A "business combination" also includes
a sale or other disposition to the interested shareholder or any affiliate or
associate of the interested shareholder of assets of the corporation or any
subsidiary (i) having an aggregate market value equal to 10% or more of the
aggregate market value of the corporation's consolidated assets, (ii) having an
aggregate market value equal to 10% or more of the aggregate market value of all
the outstanding shares of such corporation, or (iii) representing 10% or more of
the consolidated earning power or net income of such corporation. A "business
combination" also includes certain transactions with an interested shareholder
involving the issuance of shares of a corporation or its subsidiary having an
aggregate market value equal to 5% or more of the aggregate market value of all
outstanding shares under certain circumstances, the adoption of a plan for the
liquidation or dissolution of the corporation pursuant to certain agreements
with an interested shareholder and certain reclassifications and loans involving
the interested shareholder. The prohibition against such business combinations
does not apply under specified circumstances and if the corporation has opted
out of this provision. FNB has not opted out of this statutory provision.

         The FBCA contains a number of provisions which require supermajority
approval for certain affiliate transactions.


                                       70
   79


         Under the FBCA, any merger, consolidation, disposition of all or a
substantial part of the assets of the corporation or a subsidiary of the
corporation, or exchange of securities requiring shareholder approval (a
"Business Combination"), if any person who together with his affiliates and
associates beneficially owns 5% or more of any voting stock of the corporation
(an "Interested Person") is a party to such transaction, shall be approved by
the affirmative vote of the holders of two-thirds of the voting shares other
than the shares beneficially owned by the Interested Person; provided, that such
approval is not required if (a) the Interested Shareholder Transaction has been
approved by a majority of the disinterested directors; (b) the corporation has
not had more than 300 shareholders of record at any time during the three years
preceding the announcement date; (c) the Interested Person has been the
beneficial owner of at least 80% of the corporation's outstanding voting shares
for at least five years preceding the announcement date; (d) the Interested
Person is the beneficial owner of at least 90% of the outstanding voting shares
of the corporation, exclusive of shares acquired directly from the corporation
in a transaction not approved by a majority of the disinterested directors; (e)
the corporation is an investment company registered under the Investment Company
Act of 1940; or (f) the consideration to be received by holders of the stock of
the corporation meets certain minimum levels determined by a formula under
Section 607.0901(4)(f) of the FBCA (generally, the highest price paid by the
Interested Person for any shares which she or he has acquired).

FIDUCIARY DUTY

         Under the PBCL a director may, in considering the best interests of a
corporation, consider (i) the effects of any action on shareholders, employees,
suppliers, customers and creditors of the corporation, and upon communities in
which offices or other facilities of the corporation are located, (ii) the
short-term and long-term interests of the corporation, including the possibility
that the best interests of the corporation may be served by the continued
independence of the corporation, (iii) the resources, intent and conduct of any
person seeking to acquire control of the corporation, and (iv) all other
pertinent factors.

         The FNB Charter provides that the FNB Board, in evaluating a proposal
for an extraordinary corporate transaction, shall consider all relevant factors,
including the economic effect, both immediate and long-term, upon the FNB
shareholders, including shareholders, if any, who will not participate in the
transaction; the social and economic effect on the employees, depositors and
customers of, and others dealing with, FNB and its subsidiaries and on the
communities in which FNB and its subsidiaries operate or are located; whether
the proposal is acceptable based on the historical and current operating results
or financial condition of FNB; whether a more favorable price could be obtained
for FNB's securities in the future; the reputation and business practices of the
offeror and its management and affiliates as they would affect the employees,
depositors and customers of FNB and its subsidiaries; and the future value of
FNB's stock; and any antitrust or other legal and regulatory issues that are
raised by the proposal. The FNB Charter further provides that, if the FNB Board
determines that such a proposal should be rejected, it may take any lawful
action to accomplish its purposes.

         Under Florida law, a director is required to discharge his or her
duties in good faith, with the care an ordinarily prudent person in the like
position would exercise under similar circumstances and in a manner reasonably
believed to be in the best interest of the corporation. In discharging his or
her duties, a director is entitled to rely on: (i) information, opinions,
reports, or statements, including financial statements and other financial data,
if presented or prepared by officers or employees of the corporation whom the
director reasonably believes to be reliable and competent in the matters
presented; (ii) legal counsel, public accountants or other persons as to matters
the director reasonably believes are within the person's professional or expert
competence; or (iii) a committee of the board of which the director is not a
member if the director reasonably believes the committee merits confidence. In
addition, in discharging his or her duties, a director may consider such factors
as the director deems relevant, including the long-term prospectus and interest
of the corporation and its shareholders, and the social, economic, legal, or
other effects of any action on the employees, suppliers,


                                       71
   80


customers of the corporation or its subsidiaries, the communities and society in
which the corporation or its subsidiaries operate, and the economy of the state
and the nation.

PROVISIONS WITH POSSIBLE ANTI-TAKEOVER EFFECTS

         FNB is subject to various statutory "anti-takeover" provisions of the
PBCL, including Subchapters 25E, 25F, 25G and 25H of the PBCL. Subchapter 25E of
the PBCL (relating to control transactions) provides that, if any person or
group acquires 20% or more of the voting power of a covered corporation, the
remaining shareholders may demand from such person or group the fair value of
their shares, including a proportionate amount of any control premium.
Subchapter 25F of the PBCL (relating to business combinations) delays for five
years and imposes conditions upon business combinations between an interested
shareholder and the corporation. As described above, the term "business
combination" is defined broadly to include various transactions utilizing a
corporation's assets for purchase price amortization or refinancing purposes,
and an "interested shareholder" is defined generally as the beneficial owner of
at least 20% of a corporation's voting shares. See "-- Interested Shareholder
Transactions." Subchapter 25G of the PBCL (relating to control-share
acquisitions) prevents a person who has acquired 20% or more of the voting power
of a covered corporation from voting such shares unless the disinterested
shareholders approve such voting rights. Failure to obtain such approval exposes
the owner to the risk of a forced sale of stock to the issuer. If shareholder
approval is obtained, the corporation is also subject to Subchapters 25I and 25J
of the PBCL. Subchapter 25I of the PBCL provides for a minimum severance payment
to certain employees terminated within two years of the approval. Subchapter 25J
of the PBCL prohibits the abrogation of certain labor contracts prior to their
stated date of expiration. Subchapter 25H of the PBCL (relating to disgorgement)
applies in the event that (1) any person or group publicly discloses that the
person or group may acquire control of the corporation or (2) a person or group
acquires (or publicly discloses an offer or intent to acquire) 20% or more of
the voting power of the corporation and, in either case, sells shares within 18
months thereafter. Any profits from sales of equity securities of the
corporation by the person or group during the 18-month period belong to the
corporation if the securities that were sold were acquired during the 18-month
period or within 24 months prior thereto. Subchapters 25E, 25F, 25G and 25H of
the PBCL contain a wide variety of transactional and status exemptions,
exclusions and safe harbors.

         In addition, the PBCL permits an amendment of the corporation's charter
or other corporation action, if approved by shareholders generally, to provide
mandatory special treatment for specified groups of nonconsenting shareholders
of the same class by providing, for example, that shares of common stock held
only by designated shareholders of record, and no other shares of common stock,
shall be cashed out at a price determined by the corporation, subject to
applicable dissenters' rights. The PBCL also provides that directors may, in
discharging their duties, consider the interests of a number of different
constituencies, including shareholders, employees, suppliers, customers,
creditors and the communities in which the corporation is located. Directors are
not required to consider the interests of shareholders to a greater degree than
other constituencies' interests. The PBCL expressly provides that directors do
not violate their fiduciary duties solely by relying on poison pills or the
anti-takeover provisions of the PBCL.

         The business combination provisions of the PBCL may have the effect of
deterring merger proposals, tender offers or other attempts to effect changes in
control of FNB that are not negotiated with and approved by the FNB Board. FNB
is not aware of any effort or intent to gain control of FNB or any effort to
organize a proxy contest or to accumulate FNB's shares.

         Additionally, the following provisions of the FNB Charter and the FNB
Bylaws may be considered to have anti-takeover implications: (1) the ability of
the FNB Board to fill the vacancies (but only until the next


                                       72
   81


selection of the class of directors for which such director has been chosen)
resulting from an increase in the number of directors; (2) the ability of the
FNB Board to issue substantial amounts of FNB Common Stock without the need for
shareholder approval, which FNB Common Stock, among other things and in certain
circumstances, may be used to dilute the stock ownership of holders of FNB
Common Stock seeking to obtain control of FNB; (3) the ability of the FNB Board
to establish the rights of, and to issue, substantial amounts of FNB Preferred
Stock without the need for shareholder approval which FNB Preferred Stock, among
other things, may be used to create voting impediments with respect to changes
in control of FNB or, to dilute the stock ownership of holders of FNB Common
Stock seeking to obtain control of FNB; (4) the supermajority voting
requirements for certain extraordinary corporate transactions; and (5) the broad
range of factors that the FNB Board may consider in evaluating such a proposal,
and the broad range of actions it may take to reject such a proposal, if it so
decides.

         Section 607.0902 of the FBCA restricts the voting rights of certain
shares of a corporation's stock when those shares are acquired by a party who,
by such acquisition, would control at least one-fifth of all voting rights of
the corporation's issued and outstanding stock. The statute provides that the
acquired shares (the "control shares") will, upon such acquisition, cease to
have any voting rights. The acquiring party may, however, petition the
corporation to have voting rights re-assigned to the control shares by way of an
"acquiring person's statement" submitted to the corporation in compliance with
the requirements of the statute. Upon receipt of such request, the corporation
must submit, for shareholder approval, the acquiring person's request to have
voting rights re-assigned to the control shares. Voting rights may be reassigned
to the control shares by a resolution of a majority of the corporation's
shareholders for each class and series of stock. If such a resolution is
approved, and the voting rights re-assigned to the control shares represent a
majority of all voting rights of the corporation's outstanding voting stock,
then, unless the corporation's articles of incorporation or bylaws provide
otherwise, all shareholders of the corporation shall be able to exercise
dissenter's rights in accordance with Florida law.

         A corporation may, by amendment to its articles of incorporation or
bylaws, provide that, if the party acquiring the control shares does not submit
an acquiring person's statement in accordance with the statute, the corporation
may redeem the control shares at any time during the period ending 60 days after
the acquisition of control shares. If the acquiring party files an acquiring
person's statement, the control shares are not subject to redemption by the
corporation unless the shareholders, acting on the acquiring party's request,
deny full voting rights to the control shares.

         The statute does not alter the voting rights of any stock of the
corporation acquired in any of the following manners: (i) pursuant to the laws
of intestate succession or pursuant to a gift or testamentary transfer; (ii)
pursuant to the satisfaction of a pledge or other security interest created in
good faith and not for the purpose of circumventing the statute; (iii) pursuant
to either a merger or share exchange if the corporation is a party to the
agreement or plan of merger or share exchange; (iv) pursuant to any savings,
employee stock ownership or other benefit plan of the corporation; or (v)
pursuant to an acquisition of shares specifically approved by the board of
directors of the corporation.

         In addition, there are various provisions in the Citizens Charter and
the Citizens Bylaws that may serve as anti-takeover protections including: (i)
the ability of the Citizens Board to fill vacancies (but only until the next
selection of the class of directors for which such director has been chosen)
resulting from an increase in the number of directors; (ii) the supermajority
voting requirements for certain corporate transactions; (iii) the prohibition on
shareholder action by written consent; and (iv) the broad range of factors that
the Citizens Board may consider in evaluating an unsolicited offer including a
tender offer proposal. In addition, the Citizens Charter authorizes the Citizens
Board, without further shareholder action, to issue from time to time, up to
2,000,000 shares of Citizens Preferred Stock. The Citizens Board is empowered to
divide any and all of the


                                       73
   82


shares of the Citizens Preferred Stock into series and to fix and determine the
relative rights and preferences of the shares of any series so established.

         Neither FNB nor Citizens currently has a shareholders' rights plan.
Shareholders' rights plans, in a variety of forms, are common to many
corporations incorporated in the United States and serve to afford a
corporation's board of directors the opportunity to withstand an unsolicited
takeover attempt while providing the board sufficient time to evaluate the offer
and its adequacy and to consider alternative measures or transactions that may
be appropriate in responding to the offer. Both the PBCL and FBCA permit
shareholders' rights plans in general and permit the adoption of shareholders'
rights plans by a board of directors without shareholder approval.

                                 LEGAL OPINIONS

         The legality of the shares of FNB Common Stock to be issued to the
holders of Citizens Common Shares pursuant to its merger will be passed upon by
Cohen & Grigsby, P.C., Pittsburgh, Pennsylvania. Cohen & Grigsby, P.C. has from
time to time acted as counsel in advising FNB and its affiliates with respect to
certain matters and in connection with various transactions. Cohen & Grigsby,
P.C. did not act as counsel to FNB or its affiliates with respect to the merger
or any transaction in connection therewith.

         The Merger Agreement provides as a condition to each party's obligation
to consummate the merger that FNB and Citizens receive the opinion of Smith,
Gambrell & Russell, LLP, Atlanta, Georgia, special counsel to FNB, substantially
to the effect that the merger will constitute a "reorganization" under Section
368(a) of the Code.

                          INDEPENDENT AUDITORS' REPORT




To the Board of Directors and Stockholders of
Citizens Holding Corporation
Clearwater, Florida:

         We have audited the accompanying consolidated balance sheets of
Citizens Holding Corporation and Subsidiaries (the "Company") at December 31,
1997 and 1996 and the related consolidated statements of earnings, comprehensive
income, stockholders' equity and cash flows for the years then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of the Company
at December 31, 1997 and 1996 and the results of its operations and its cash
flows for the years then ended, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                           DECEMBER 31, 1997 AND 1996


(1)  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     GENERAL. Citizens Holding Corporation (the "Holding Company") owns 100% of
         the outstanding stock of Citizens Bank and Trust (the "Bank")
         (collectively the "Company"). The Bank is state chartered and insured
         by the Federal Deposit Insurance Corporation. In July 1997, the Bank
         formed CBORE, Inc., a 100% owned subsidiary. The subsidiary's only
         business activity is the ownership of foreclosed real estate. At
         December 31, 1997, there was no foreclosed real estate. The Holding
         Company operates as a one bank-holding company. The Holding Company's
         only business activity is the operation of the Bank. The Bank provides
         a wide range of banking services to small and middle-market businesses
         and individuals through its six banking offices in Pinellas County,
         Florida.

     BASIS OF PRESENTATION. The accompanying consolidated financial statements
         include the accounts of the Holding Company and its subsidiaries. All
         significant intercompany accounts and transactions have been eliminated
         in consolidation. The accounting and reporting practices of the Company
         conform to generally accepted accounting principles and to general
         practices within the banking industry. The following summarizes the
         more significant of these polices and practices:

     ESTIMATES. The preparation of financial statements in conformity with
         generally accepted accounting principles requires management to make
         estimates and assumptions that affect the reported amounts of assets
         and liabilities and disclosure of contingent assets and liabilities at
         the date of the financial statements and the reported amounts of
         revenues and expenses during the reporting period. Actual results could
         differ from those estimates.

     SECURITIES AVAILABLE FOR SALE. Available-for-sale securities consist of
         securities not classified as trading securities nor as held-to-maturity
         securities. Unrealized holding gains and losses, net of tax, on
         available-for-sale securities are reported as a net amount in a
         separate component of stockholders' equity until realized. Gains and
         losses on the sale of available-for-sale securities are determined
         using the specific identification method. Premiums and discounts are
         recognized in interest income using the interest method over the period
         to maturity.

     SECURITIES HELD TO MATURITY. Securities for which the Company has the
         positive intent and ability to hold to maturity are reported at cost,
         adjusted for premiums and discounts that are recognized in interest
         income using the interest method over the period to maturity.

     LOANS RECEIVABLE. Loans receivable that management has the intent and
         ability to hold for the foreseeable future or until maturity or pay-off
         are reported at their outstanding principal adjusted for any
         charge-offs, the allowance for loan losses, and any deferred fees or
         costs on originated loans.

         Loan origination fees and certain direct origination costs are
         capitalized and recognized as an adjustment of the yield of the related
         loan.

                                                                     (continued)

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED


(1)  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES,
     CONTINUED LOANS RECEIVABLE, CONTINUED.  The accrual of interest on impaired
         loans is discontinued when, in management's opinion, the borrower may 
         be unable to meet payments as they become due. When interest accrual is
         discontinued, all unpaid accrued interest is reversed. Interest income
         is subsequently recognized only to the extent cash payments are
         received.

         The allowance for loan losses is increased by charges to earnings and
         decreased by charge-offs (net of recoveries). Management's periodic
         evaluation of the adequacy of the allowance is based on the Company's
         past loan loss experience, known and inherent risks in the portfolio,
         adverse situations that may affect the borrower's ability to repay, the
         estimated value of any underlying collateral, and current economic
         conditions.

     FORECLOSED REAL ESTATE. Real estate properties acquired through, or in lieu
         of, loan foreclosure are to be sold and are initially recorded at fair
         value at the date of foreclosure establishing a new cost basis. After
         foreclosure, valuations are periodically performed by management and
         the real estate is carried at the lower of carrying amount or fair
         value less cost to sell. Revenue and expenses from operations and
         changes in the valuation allowance are included in the consolidated
         statements of earnings.

     TRUST FEES. Trust fees are recorded on the accrual basis. Securities and
         other property held by the trust department in a fiduciary or agency
         capacity are not included in the balance sheet since such items are not
         assets of the Company.

     PREMISES AND EQUIPMENT. Land is carried at cost. Bank premises, furniture
         and fixtures, equipment and leasehold improvements are carried at cost,
         less accumulated depreciation and amortization computed by the
         straight-line method over the estimated useful lives of the assets.

     ADVERTISING.  The Company expenses all media advertising as incurred.

     INCOME TAXES. Deferred tax assets and liabilities are reflected at
         currently enacted income tax rates applicable to the period in which
         the deferred tax assets or liabilities are expected to be realized or
         settled. As changes in tax laws or rates are enacted, deferred tax
         assets and liabilities are adjusted through the provision for income
         taxes.

     OFF-BALANCE-SHEET INSTRUMENTS. In the ordinary course of business the
         Company has entered into off-balance-sheet financial instruments
         consisting of commitments to extend credit and standby letters of
         credit. Such financial instruments are recorded in the financial
         statements when they are funded or related fees are incurred or
         received.

                                                                     (continued)

(1)  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES,
     CONTINUED EARNINGS PER SHARE. Earnings per share ("EPS") of common stock
         has been computed on the basis of the weighted-average number of shares
         of common stock outstanding. For purposes of calculating diluted EPS
         because there is no active trading market for the Company's common
         stock, the average book value per share was used.



                                                          FOR THE YEAR ENDED DECEMBER 31,

(1)  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES,
     CONTINUED FAIR VALUES OF FINANCIAL INSTRUMENTS, CONTINUED.
         LOANS RECEIVABLE. For variable-rate loans that reprice frequently and
         have no significant change in credit risk, fair values are based on
         carrying values. Fair values for fixed-rate residential mortgage loans
         and fixed-rate commercial real estate and commercial loans are
         estimated using discounted cash flow analyses, using interest rates
         currently being offered for loans with similar terms to borrowers of
         similar credit quality. Fair values for impaired loans are estimated
         using discounted cash flow analyses or underlying collateral values,
         where applicable.

         FEDERAL HOME LOAN BANK STOCK.  The carrying amount approximates fair
         value.

         ACCRUED INTEREST.  The carrying amount of accrued interest approximates
         their fair value.

         DEPOSIT LIABILITIES. The fair values disclosed for demand, savings and
         NOW deposits are, by definition, equal to the amount payable on demand
         at the reporting date (that is, their carrying amounts). Fair values
         for fixed-rate certificates of deposit are estimated using a discounted
         cash flow calculation that applies interest rates currently being
         offered on certificates to a schedule of aggregate expected monthly
         maturities on time deposits.

         SECURITIES SOLD UNDER REPURCHASE AGREEMENTS.  For these short term 
         liabilities the carrying value is a reasonable estimate of fair value.

         OFF-BALANCE-SHEET INSTRUMENTS. Fair values of off-balance-sheet lending
         commitments are based on fees currently charged to enter into similar
         agreements, taking into account the remaining terms of the agreements
         and the counterparties' credit standings.

                                                                     (continued)

     Actual maturities may differ from contractual maturities because borrowers
         may have the right to call or prepay obligations with or without call
         or prepayment penalties.

     On  April 30, 1994 the Company reclassified certain securities from

(6)  SECURITIES SOLD UNDER REPURCHASE AGREEMENTS
     The Company has entered into repurchase agreements with certain customers,
         whereby the Company has agreed to sell certain securities held in its
         investment portfolio in return for a simultaneous commitment by the
         customer to resell the securities back to the Company. In effect, the
         Company's customer purchases eligible securities from the Company for a
         specified period of time and agrees to sell those securities back to
         the Company upon maturity of the transactions. The customers earn a
         specific rate of interest, payable daily for the duration of the
         transaction, that bears no relation to the interest rate of the
         underlying security. Amounts outstanding at December 31, 1997 and 1996
         under these repurchase agreements were $3,434,034 and $1,845,921,
         respectively. The Company has secured the repurchase agreements by
         pledging securities from its investment portfolio in an equivalent
         amount.

     Information concerning securities sold under agreements to repurchase is
summarized as follows:



                                                                                         YEAR ENDED DECEMBER 31,

(8)  DEFERRED COMPENSATION PLANS
     In 1996, the Board of Directors approved deferred compensation agreements
         for certain officers of the Company and one former officer of the
         Company. The terms of the agreements provide for the payments of
         specified benefits to these participants or their beneficiaries at the
         earlier of retirement or death of the participant. The Company is
         accruing the present value of the future benefits over the term of the
         agreements. The Company has purchased life insurance policies on the
         participants which although not formally linked, have future cash
         values that exceed the estimated future benefits. The net expense of
         the deferred compensation plans and life insurance premiums, net of the
         increase in the cash surrender value of the insurance policies was
         approximately $4,700 and $1,246,000 for the years ended December 31,
         1997 and 1996, respectively.

(9)  STOCKHOLDERS' EQUITY
     The ability of the Holding Company to pay dividends to the stockholders is
         dependent upon receiving dividends from the Bank. The Bank is subject
         to certain restrictions on the amount of dividends that it may declare
         without prior regulatory approval.

(10) REGULATORY MATTERS
     The Bank is subject to various regulatory capital requirements administered
         by the federal banking agencies. Failure to meet minimum capital
         requirements can initiate certain mandatory-and possibly additional
         discretionary-actions by regulators that, if undertaken, could have a
         direct material effect on the Bank's financial statements. Under
         capital adequacy guidelines and the regulatory framework for prompt
         corrective action, the Bank must meet specific capital guidelines that
         involve quantitive measures of the Bank's assets, liabilities, and
         certain off-balance-sheet items as calculated under regulatory
         accounting practices. The Bank's capital amounts and classifications
         are also subject to qualitative judgements by the regulators about
         components, risk weightings, and other factors.

     Quantitative measures established by regulation to ensure capital adequacy
         require the Bank to maintain minimum amounts and ratios (set forth in
         the table below) of total and Tier I capital (as defined in the
         regulations) to risk-weighted assets (as defined), and of Tier I
         capital (as defined) to average assets (as defined). Management
         believes, as of December 31, 1997, that the Bank meets all capital
         adequacy requirements to which it is subject.

                                                                     (continued)

(10) REGULATORY MATTERS, CONTINUED
     As  of December 31, 1997, the most recent notification from the state
         regulatory authorities categorized the Bank as well capitalized under
         the regulatory framework for prompt corrective action. To be
         categorized as well capitalized the Bank must maintain minimum total
         risk-based, Tier I risk-based, and Tier I leverage ratios as set forth
         in the table. There are no conditions or events since that notification
         that management believes have changed the Bank's category. The Bank's
         actual capital amounts and ratios are also presented in the table.

(11) RELATED PARTIES
     Several directors of the Company and their companies and ventures obtain
         loans from the Company. These loans were granted in accordance with the
         normal lending policies of the Company. At December 31, 1997 and 1996,
         the total amount of borrowings outstanding to these related parties
         were approximately $1,844,000 and $1,513,000, respectively. During 1997
         new loans to these related parties amounted to $779,000 and repayments
         amounted to $448,000. In addition, deposits from these related parties
         approximated $2,386,000 and $1,689,000 at December 31, 1997 and 1996,
         respectively.

     The Company also has business relationships with other entities under the
         direct or indirect control of management, stockholders, and/or
         directors of the Company. These relationships, which are in the
         ordinary course of business, include placement of insurance coverage,
         legal services, and the construction of leasehold improvements.

(12) EMPLOYEE STOCK OPTION PLAN
     The Bank had a nonqualified Employee Stock Option Plan (the "Plan") which
         was adopted by the Holding Company whereby one hundred thousand
         (100,000) shares of the Holding Company's common stock are reserved for
         issuance to directors and certain officers and other employees of the
         Company.
                                                                     (continued)

(12) EMPLOYEE STOCK OPTION PLAN, CONTINUED
     During 1987, stock options to acquire 58,000 shares were granted. These
         options expire twenty years after date of grant and are exercisable at
         $10.55. During March 1993, stock options to acquire the remaining
         42,000 shares of the Holding Company were granted to certain directors
         of the Holding Company, as well as officers of the Bank. These options
         expire twenty years after the date of grant and are exercisable at
         $11.23 per share. 4,000 of these options were exercised in 1995. A
         summary of activity for the years ended December 31, 1997 and 1996 is
         as follows:

     There were no options granted or exercised during the years ended December
31, 1997 or 1996.

(13) RETIREMENT PLAN
     The Bank has implemented a Section 401(k) Employee Savings Plan (the
         "Plan"). Under the Plan, employees become eligible after completion of
         1,000 hours of employment service. The Bank paid matching contributions
         of $74,356 and $62,805 in 1997 and 1996 respectively, representing 100%
         of the employee contributions to the Plan, up to 6% of the salaries of
         the participants.

(14) COMMITMENTS AND CONTINGENCIES
     In  the ordinary course of business, the Company has various outstanding
         commitments and contingent liabilities that are not reflected in the
         accompanying consolidated financial statements. In addition, the
         Company is a defendant in certain claims and legal actions arising in
         the ordinary course of business. In the opinion of management, after
         consultation with legal counsel, the ultimate disposition of these
         matters is not expected to have a material adverse effect on the
         consolidated financial condition of the Company.

     The Bank's Board of Directors has executed an employment contract for one
         executive officer which includes provisions for minimum salary levels,
         severance pay ranging from two to three years salary in the event of
         termination under certain circumstances, and provisions for car
         allowances and other reimbursable expenses. This contract covers an
         indefinite period of time.

     On December 16, 1997, the Company's Board of Directors authorized the
         repurchase of up to 30,000 shares of common stock at $25 per share. The
         Company initially offered to repurchase 24,000 shares of common stock.
         The offer expires January 31, 1998 and may be withdrawn or extended by
         the Company. At December 31, 1997, the Company has received requests
         from stockholders to repurchase 700 shares of common stock for an
         aggregate total of $17,500. These transactions have not been reflected
         in the accompanying financial statements because they were not
         consummated at December 31, 1997. The Company obtained a $1,500,000
         uncollateralized credit facility with a financial institution to
         finance the stock repurchase. The credit facility bears interest at
         Libor, plus 2.1%, interest is payable quarterly and the facility
         matures September 30, 1998. The credit facility is subject to certain
         restrictive covenants as defined in the agreement. At December 31,
         1997, there were no borrowings outstanding under this agreement.

                                                                     (continued)

(15)  FINANCIAL INSTRUMENTS
     The Company is a party to financial instruments with off-balance-sheet risk
         in the normal course of business to meet the financing needs of its
         customers. These financial instruments include commitments to extend
         credit and standby letters of credit. These instruments involve, to
         varying degrees, elements of credit and interest-rate risk in excess of
         the amounts recognized in the consolidated balance sheet. The contract
         or notional amounts of those instruments reflect the extent of the
         Company's involvement in particular classes of financial instruments.

     The Company's exposure to credit loss in the event of nonperformance by the
         other party to the financial instrument for commitments to extend
         credit and standby letters of credit is represented by the contractual
         notional amount of those instruments. The Company uses the same credit
         policies in making commitments as it does for on-balance-sheet
         instruments.

     Commitments to extend credit are agreements to lend to a customer as long
         as there is no violation of any condition established in the contract.
         Commitments general have fixed expiration dates or other termination
         clauses and may require payment of a fee. Since many of the commitments
         are expected to expire without being drawn upon, the total commitments
         amounts do not necessarily represent future cash requirements. The
         Company evaluates each customer's credit worthiness on a case-by-case
         basis. The amount of collateral obtained, if it is deemed necessary by
         the Company upon extension of credit, is based on management's credit
         evaluation of the counter party. Collateral held varies but may include
         accounts receivable; inventory, property, plant, and equipment and
         income-producing commercial properties.

     Standby letters of credit are conditional commitments issued by the Company
         to guarantee the performance of a customer to a third party. The credit
         risk involved in issuing letters of credit to customers is essentially
         the same as that involved in extending loan facilities to customers.

     The estimated fair values of the Company's financial instruments are as
follows:



                                                        AT DECEMBER 31, 1997               AT DECEMBER 31, 1996

(16) SIGNIFICANT GROUP CONCENTRATION OF CREDIT RISK
     Most of the Company's business activity is with customers located within
         the Pinellas County, Florida area. Therefore, the Company's exposure to
         credit risk is significantly affected by changes in the economy in the
         Pinellas County area. The loan portfolio is diversified among
         individuals and types of industries. Loans are expected to be repaid
         from cash flow or proceeds from the sale of selected assets of the
         borrowers. The distribution of commitments to extend credit
         approximates the distribution of loans outstanding. Standby letters of
         credit were granted primarily to commercial borrowers. The contractual
         amounts of credit related financial instruments such as commitments to
         extend credit and standby letters of credit represent the amounts of
         potential accounting loss should the contract be fully drawn upon, the
         customer default, and the value of any existing collateral become
         worthless.

(18) SUBSEQUENT EVENTS
     On April 6, 1998, the Board of Directors of the Company approved a
         definitive agreement for the merger of the Company into another
         financial institution (Southwest Banks, Inc.) and authorized the
         Company's President and Chief Executive Officer to execute the
         agreement on behalf of the Company on the same date. The merger is
         expected to be completed in the third quarter of 1998 and is subject to
         various regulatory approvals as well as the approval of the
         shareholders of the Company.

     In addition, during the three months ended March 31, 1998, the Company
         repurchased 23,205 shares of its common stock (See Note 14).

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


1.  GENERAL. In the opinion of the management of Citizens Holding
        Corporation (the "Holding Company"), the accompanying condensed
        consolidated financial statements contain all adjustments (consisting
        principally of normal recurring accruals) necessary to present fairly
        the financial position at March 31, 1998 and the results of operations,
        comprehensive income and cash flows for the three-month periods ended
        March 31, 1998 and 1997. The results of operations for the three months
        ended March 31, 1998 are not necessarily indicative of the results to be
        expected for the full year.

        The Holding Company's condensed consolidated financial statements
        include the accounts of its wholly-owned subsidiary, Citizens Bank and
        Trust (the "Bank") (collectively the "Company"). The Holding Company's
        only business activity is the ownership of the Bank. All intercompany
        accounts and transactions have been eliminated in consolidation.

2.  LOAN IMPAIRMENT AND CREDIT LOSSES. A loan totaling $90,078 was
        identified as being impaired during the three-month period ended March
        31, 1998. The activity in the allowance for loan losses is as follows:

3.  EARNINGS PER SHARE. Earnings per share ("EPS") of common stock has been
        computed on the basis of the weighted-average number of shares of common
        stock outstanding. For purposes of calculating diluted EPS because there
        is no active trading market for the Company's common stock, the average
        book value per share was used.

                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") is made and
entered into as of April 6, 1998, by and among F.N.B. CORPORATION ("FNB"), a
Pennsylvania corporation having its principal office located in Hermitage,
Pennsylvania; SOUTHWEST BANKS, INC. ("Southwest"), a Florida corporation having
its principal office located in Naples, Florida, and a wholly owned subsidiary
of FNB; and CITIZENS HOLDING CORPORATION ("CHC"), a Florida corporation having
its principal office located in Clearwater, Florida.

                                    PREAMBLE

         The Boards of Directors of CHC and FNB are of the opinion that the
acquisition described herein is in the best interests of the parties and their
respective shareholders. This Agreement provides for the acquisition of CHC by
FNB pursuant to the merger of CHC with and into Southwest (the "Merger"). At the
effective time of such Merger, the outstanding shares of the capital stock of
CHC shall be converted into the right to receive shares of the common stock of
FNB (except as provided herein). As a result, shareholders of CHC shall become
shareholders of FNB. Immediately upon consummation of the Merger, Citizens Bank
& Trust, a wholly owned subsidiary of CHC, shall be merged into First National
Bank of Florida, a wholly owned subsidiary of Southwest. The transactions
described in this Agreement are subject to the approvals of the shareholders of
CHC, the Board of Governors of the Federal Reserve System, the Florida
Department of Banking and Finance, and the satisfaction of certain other
conditions described in this Agreement. It is the intention of the parties to
this Agreement that the Merger for federal income tax purposes shall qualify as
a "reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code, and for accounting purposes shall qualify for treatment as a pooling of
interests.

         Contemporaneously with the execution and delivery of this Agreement, as
a condition and inducement to FNB's willingness to enter into this Agreement,
CHC and FNB are entering into a stock option agreement (the "Stock Option
Agreement"), in substantially the form of Exhibit 1, pursuant to which CHC is
granting to FNB an option to purchase shares of CHC Common Stock.

         Certain terms used in this Agreement are defined in Section 11.1 of
this Agreement.

         NOW, THEREFORE, in consideration of the above and the mutual
warranties, representations, covenants, and agreements set forth herein, the
parties agree as follows:

                                    ARTICLE 1

                        TRANSACTIONS AND TERMS OF MERGER

         1.1 Merger. Subject to the terms and conditions of this Agreement, at
the Effective Time, CHC shall be merged with and into Southwest in accordance
with the provisions of the FBCA. At the Effective Time, the separate existence
of CHC shall cease, and Southwest, which shall remain a wholly-owned subsidiary
of FNB, shall be the Surviving Corporation resulting from the Merger and shall
continue to be governed by the Laws of the State of Florida. From and after the
Effective Time, the Merger shall have the effects specified in the FBCA. The
Merger shall be consummated pursuant to the terms of this Agreement, which has
been approved and adopted by the respective Boards of Directors of CHC, FNB, and
Southwest.

         1.2 Time and Place of Closing. The closing of the transactions
contemplated by this Agreement (the "Closing"), including the Merger, shall take
place at 10:00 A.M., local time, on a date specified by the 



                                      A-1
   122

Parties as they, acting through their chief executive officers or chief
financial officers, may mutually agree. Subject to the terms and conditions
hereof, unless mutually agreed upon in writing by each Party, the Parties shall
use their reasonable best efforts to cause the Closing to occur on, but not
prior to, the fifth business day following the Determination Date.

         1.3 Effective Time. The Merger and other transactions contemplated by
this Agreement shall become effective on the date and at the time (the
"Effective Time") on which the Florida Articles of Merger containing the
provisions required by, and executed in accordance with, the FBCA shall have
been accepted for filing by the Secretary of State, State of Florida, or such
later date and time as is agreed in writing by FNB and CHC and specified in the
Florida Articles of Merger. Unless FNB and CHC otherwise mutually agree in
writing, the Parties to this Agreement shall use their best efforts to cause the
Effective Time occur on the date of Closing.

         1.4 Execution of Stock Option Agreement. Concurrently with the
execution and delivery of this Agreement, and as a condition thereto, CHC is
executing and delivering to FNB the Stock Option Agreement.

                                    ARTICLE 2

                                 TERMS OF MERGER

         2.1 Articles of Incorporation. Pursuant to the Merger, the Articles of

of Incorporation of the Surviving Corporation until otherwise amended or
repealed in accordance with applicable Law.

         2.2 Bylaws. Pursuant to the Merger, the Bylaws of Southwest in effect
at the Effective Time shall be the Bylaws of the Surviving Corporation until
otherwise amended or repealed in accordance with applicable Law.

         2.3 Directors. Upon the Effective Time, the directors of CHC shall be
elected as directors of First National Bank of Florida for a term of one year
and FNB shall cause directors fees to be paid to such individuals for such term
in an amount at least equal to the amount currently paid to the CHC directors.

                                    ARTICLE 3

                           MANNER OF CONVERTING SHARES

         3.1 Conversion of Shares. Subject to the provisions of this Article 3,
at the Effective Time, by virtue of the Merger and without any action on the
part of FNB, Southwest or CHC, or the shareholders of any of the foregoing, the
shares of the constituent corporations shall be converted as follows:

             (a) Each of the Surviving Corporation common shares issued and
         outstanding immediately prior to the Effective Time shall remain
         outstanding and issued entirely to FNB.

             (b) Each share of FNB Capital Stock issued and outstanding
         immediately prior to the Effective Time shall remain issued and
         outstanding from and after the Effective Time.



                                      A-2
   123

             (c) Except for CHC Common Shares issued and outstanding immediately
         prior to the Effective Time as to which dissenters' rights have been
         perfected and not withdrawn, and subject to Section 3.4 relating to
         fractional shares, each CHC Common Share (excluding shares to be
         cancelled pursuant to Section 3.3 of this Agreement) issued and
         outstanding at the Effective Time shall cease to be outstanding and
         shall be converted into and exchanged for 1.515 shares of FNB Common
         Stock (the "Exchange Ratio").

             (d) If the Designated Price of FNB Common Stock shall be less than
         $34.125, then CHC may, at any time during the period commencing on the
         Determination Date and ending at the close of business five (5)
         business days thereafter, terminate the Agreement pursuant to Section
         10.1(g) hereof.

             (e) Notwithstanding Section 3.1(c) of this Agreement, CHC Common
         Shares issued and outstanding at the Effective Time which is held by a
         holder who has not voted in favor of the Merger and who has demanded
         payment for such shares in accordance with Section 607.1320 of the FBCA
         ("Dissenting CHC Shares") shall not be converted into or represent the
         right to receive the FNB Common Stock payable thereon pursuant to
         Section 3.1(c) of this Agreement, and shall be entitled only to such
         rights of appraisal as are granted by Section 607.1320 of the FBCA
         ("Dissent Provisions"), unless and until such holder fails to perfect
         or effectively withdraws or otherwise loses his right to appraisal. If
         after the Effective Time any such holder fails to perfect or
         effectively withdraws or loses his right to appraisal, such CHC Common
         Shares shall be treated as if they had been converted at the Effective
         Time into the right to receive the FNB Common Stock payable thereon
         pursuant to Section 3.1(c) of this Agreement. CHC shall give FNB prompt
         notice upon receipt by CHC of any written objection to the Merger and
         such written demands for payment on CHC Common Shares under the Dissent
         Provisions, and the withdrawals of such demands, and any other
         instruments provided to CHC pursuant to the Dissent Provisions (any
         shareholder duly making such demand being hereinafter called a
         "Dissenting Shareholder"). Each Dissenting Shareholder that becomes
         entitled, pursuant to the Dissent Provisions, to payment for any CHC
         Common Shares held by such Dissenting Shareholder shall receive payment
         therefore from FNB (but only after the amount thereof shall have been
         agreed upon or at the times and in the amounts required by the Dissent
         Provisions) and all of such Dissenting Shareholders CHC Common Shares
         shall be cancelled. CHC shall not, except with the prior written
         consent of FNB, voluntarily make any payment with respect to, or settle
         or offer to settle, any demand for payment by any Dissenting
         Shareholder.

         3.2 Anti-Dilution Provisions. In the event FNB changes the number of
shares of FNB Common Stock issued and outstanding prior to the Effective Time as
a result of a stock split, stock dividend, recapitalization, reclassification,
or similar transaction with respect to such stock and the record date therefor
(in the case of a stock dividend) or the effective date thereof (in the case of
a stock split or similar recapitalization for which a record date is not
established) shall be prior to the Effective Time, the Exchange Ratio shall be
proportionately adjusted so as to prevent the dilutive effect of such
transaction on a percentage of ownership basis; provided, however, that the
Exchange Ratio shall not be adjusted in connection with the 5% stock dividend to
be declared by FNB to shareholders of record on or about April 10, 1998.

         3.3 Shares Held by CHC or FNB. Each of the CHC Common Shares, if any,
held by any CHC Company or by any FNB Company, in each case other than in a
fiduciary capacity or as a result of debts previously contracted, shall be
canceled and retired at the Effective Time and no consideration shall be issued
in exchange therefor.



                                      A-3
   124

         3.4 Fractional Shares. Notwithstanding any other provision of this
Agreement, each holder of CHC Common Shares exchanged pursuant to the Merger who
would otherwise have been entitled to receive a fraction of a share of FNB
Common Stock (after taking into account all certificates delivered by such
holder) shall receive, in lieu thereof, cash (without interest) in an amount
equal to such fractional part of a share of FNB Common Stock multiplied by the
"market price" of one share of FNB Common Stock at the Closing. The market price
of one share of FNB Common Stock at the Effective Time shall be the closing
trade price of such common stock, as reported by Nasdaq (or, if not reported
thereby, any other authoritative source selected by FNB) on the last trading day
preceding the Closing. No such holder will be entitled to dividends, voting
rights, or any other rights as a shareholder in respect of any fractional
shares.

         3.5 Treatment of Options and Warrants.

             (a) At the Effective Time, each award, option or other right to
         purchase or acquire CHC Common Stock (collectively, the "CHC Options")
         pursuant to stock awards, stock options, stock appreciation rights, or
         other benefits granted by CHC pursuant to any employee stock option
         plan or other arrangement of CHC ("CHC Stock Plan"), which CHC Options
         are outstanding at the Effective Time of the Merger, whether or not
         such CHC Options are then vested or exercisable, shall be converted
         into and become rights with respect to FNB Common Stock, and FNB shall
         assume each CHC Option, in accordance with the terms of the CHC Stock
         Plan, Stock Option agreement, or warrant agreement by which it is
         evidenced, except that from and after the Effective Time (i) FNB and
         its Compensation Committee shall be substituted for CHC and the
         compensation committee of CHC's Board of Directors, including, if
         applicable, the entire Board of Directors of CHC, administering such
         CHC Stock Plan, (ii) each CHC Option assumed by FNB may be exercised
         solely for shares of FNB Common Stock, (iii) the number of shares of
         FNB Common Stock subject to each such CHC Option shall be equal to the
         number of shares of CHC Common Stock subject to each such CHC Option
         immediately prior to the Effective Time times the Exchange Ratio, and
         (iv) the per share exercise price under each such CHC Option will be
         adjusted by dividing the per share exercise price under each such CHC
         Option by the Exchange Ratio and rounding up to the nearest cent.
         Notwithstanding the provisions of clause (iii) of the preceding
         sentence, FNB shall not be obligated to issue any fraction of a share
         of FNB Common Stock upon exercise of CHC Options and any fraction of a
         share of FNB Common Stock that otherwise would be subject to a
         converted CHC Option shall represent the right to receive a cash
         payment equal to the product of such fraction and the difference
         between the market value of one share of FNB Common Stock and the per
         share exercise price of such Option. Notwithstanding the provisions and
         clauses (iii) and (iv) of this Section 3.5(a), each CHC Option which is
         an "incentive stock option" shall be adjusted as required by Section
         424 of the Internal Revenue Code, and the regulations promulgated
         thereunder, so as not to constitute a modification, extension, or
         renewal of the option within the meaning of Section 424(h) of the
         Internal Revenue Code. CHC and FNB agree to take all necessary steps to
         effectuate the foregoing provisions of this Section 3.5.

             (b) As soon as practicable after the Effective Time, FNB shall
         deliver to the participants in each CHC Stock Plan an appropriate
         notice setting forth such participant's rights pursuant thereto and the
         grants pursuant to such CHC Stock Plan shall continue in effect on the
         same terms and conditions (subject to the adjustments required by
         Section 3.5(a) of this Agreement after giving effect to the Merger),
         and FNB shall comply with the terms of each CHC Stock Plan to ensure,
         to the extent required by, and subject to the provisions of, such CHC
         Stock Plan, that CHC Options which qualified as incentive stock options
         prior to the Effective Time continue to qualify as incentive stock
         options after the Effective Time. At or prior to the Effective Time,
         FNB shall take all corporate action necessary to reserve for issuance
         sufficient shares of FNB Common Stock for 



                                      A-4
   125

         delivery upon exercise of CHC Options assumed by it in accordance with
         this Section 3.5. As soon as practicable after the Effective Time, FNB
         shall file a registration statement on Form S-3 or Form S-8, as the
         case may be (or any successor or other appropriate forms), with respect
         to the shares of FNB Common Stock subject to such CHC Options and shall
         use its reasonable efforts to maintain the effectiveness of such
         registration statement (and maintain the current status of the
         prospectus or the prospectuses contained therein), for so long as such
         options remain outstanding. With respect to individuals who subsequent
         to the Merger will be subject to the reporting requirements under
         Section 16(a) of the 1934 Act, where applicable, FNB shall administer
         the CHC Stock Plan assumed pursuant to this Section 3.5 in a manner
         which complies with Rule 16b-3 promulgated under the 1934 Act to the
         extent the CHC Stock Plan complied with such Rule prior to the Merger.

             (c) All restrictions or limitations on transfer with respect to the
         CHC Common Stock awarded under the CHC Stock Plan or any other plan,
         program, or arrangement of CHC, to the extent that such restrictions or
         limitations shall not have already lapsed, and except as otherwise
         expressly provided in such plan, program, or arrangement, shall remain
         in full force and effect.

                                    ARTICLE 4

                               EXCHANGE OF SHARES

         4.1 Exchange Procedures. At the Effective Time, FNB shall deposit, or
shall cause to be deposited, with the Exchange Agent selected by FNB (the
"Exchange Agent") certificates evidencing shares of FNB Common Stock and cash in
such amounts necessary to provide all consideration required to be exchanged by
FNB for CHC Common Shares pursuant to the terms of this Agreement. Promptly
after the Effective Time, FNB shall cause the Exchange Agent to mail to the
former shareholders of CHC appropriate transmittal materials (which shall
specify that delivery shall be effected, and risk of loss and title to the
certificates theretofore representing shares of CHC Common Shares shall pass,
only upon proper delivery of such certificates to the Exchange Agent). After the
Effective Time, each holder of shares of CHC Common Shares (other than shares to
be canceled pursuant to Section 3.3 of this Agreement) issued and outstanding at
the Effective Time shall surrender the certificate or certificates representing
such shares to the Exchange Agent and shall upon surrender thereof promptly
receive in exchange therefor the consideration provided in Section 3.1 of this
Agreement, together with all declared but undelivered dividends or distributions
in respect of such shares (without interest thereon) pursuant to Section 4.2 of
this Agreement. To the extent required by Section 3.4 of this Agreement, each
holder of CHC Common Shares issued and outstanding at the Effective Time also
shall receive, upon surrender of the certificate or certificates representing
such shares, cash in lieu of any fractional share of FNB Common Shares to which
such holder may be otherwise entitled (without interest). FNB shall not be
obligated to deliver the consideration to which any former holder of CHC Common
Shares is entitled as a result of the Merger until such holder surrenders such
holder's certificate or certificates representing the CHC Common Shares for
exchange as provided in this Section 4.1. The certificate or certificates of CHC
Common Shares so surrendered shall be duly endorsed as the Exchange Agent may
require. Any other provision of this Agreement notwithstanding, neither FNB nor
the Exchange Agent shall be liable to a holder of CHC Common Shares for any
amounts paid or property delivered in good faith to a public official pursuant
to any applicable abandoned property Law.

         4.2 Rights of Former CHC Shareholders. At the Effective Time, the
stock transfer books of CHC shall be closed as to holders of CHC Common Shares
immediately prior to the Effective Time and no transfers of CHC Common Shares by
any such holder shall thereafter be made or recognized. Until surrendered for
exchange in accordance with the provisions of Section 4.1 of this Agreement,
each certificate theretofore representing CHC Common Shares (other than shares
as to which dissenters' rights have been 



                                      A-5
   126

perfected under the Dissent Provisions and not withdrawn, and other than shares
to be canceled pursuant to Section 3.3 of this Agreement) shall from and after
the Effective Time represent for all purposes only the right to receive the
consideration provided in Sections 3.1 and 3.4 of this Agreement in exchange
therefor, subject, however, to FNB's obligation to pay any dividends or make any
other distributions with a record date prior to the Effective Time which have
been declared or made by CHC in respect of such CHC Common Shares in accordance
with the terms of this Agreement and which remain unpaid at the Effective Time.
Until 90 days after the Effective Time, former shareholders of record of CHC
shall be entitled to vote at any meeting of FNB stockholders the number of
shares of FNB Common Stock into which their respective CHC Common Shares are
converted, regardless of whether such holders have exchanged their certificates
representing CHC Common Shares for certificates representing FNB Common Stock in
accordance with the provisions of this Agreement. Whenever a dividend or other
distribution is declared by FNB on the FNB Common Stock, the record date for
which is at or after the Effective Time, the declaration shall include dividends
or other distributions on all shares issuable pursuant to this Agreement, but
beginning 30 days after the Effective Time no dividend or other distribution
payable to the holders of record of FNB Common Stock as of any time subsequent
to the Effective Time shall be delivered to the holder of any certificate
representing shares of CHC Common Shares issued and outstanding at the Effective
Time until such holder surrenders such certificate for exchange as provided in
Section 4.1 of this Agreement. However, upon surrender of such CHC Common Shares
certificate, both the FNB Common Stock certificate (together with all such
undelivered dividends or other distributions without interest) and any
undelivered dividends and cash payments to be paid for fractional share
interests (without interest) shall be delivered and paid with respect to each
share represented by such certificate. Any portion of the consideration
(including the proceeds of any investments thereof) which had been made
available to the Exchange Agent pursuant to Section 4.1 of this Agreement that
remain unclaimed by the shareholders of CHC for six months after the Effective
Time shall be paid to FNB. Any shareholders of CHC who have not theretofore
complied with this Article 4 shall thereafter look only to FNB for payment of
their shares of FNB Common Stock, cash in lieu of fractional shares, and unpaid
dividends and distributions on the FNB Common Stock deliverable in respect of
each CHC Common Share such shareholder holds as determined pursuant to this
Agreement, in each case, without any interest thereon.

                                    ARTICLE 5

                      REPRESENTATIONS AND WARRANTIES OF CHC

         CHC hereby represents and warrants to FNB as follows:

         5.1 Organization, Standing, and Power. CHC is a corporation duly
organized, validly existing, and in active status under the laws of the State of
Florida, and has the corporate power and authority to carry on its business as
now conducted and to own, lease, and operate its material Assets. CHC is duly
qualified or licensed to transact business as a foreign corporation and is in
good standing in each jurisdiction where the character of its Assets or the
nature or conduct of its business requires it to be so qualified or licensed,
except for such jurisdictions in which the failure to be so qualified or
licensed is not reasonably likely to have, individually or in the aggregate, a
Material Adverse Effect on the CHC and its Subsidiaries taken as a whole.



                                      A-6
   127

         5.2 Authority; No Breach by Agreement.

             (a) CHC has the corporate power and authority necessary to execute
         and deliver this Agreement and, subject to the approval and adoption of
         this Agreement by the shareholders of CHC, to perform its obligations
         under this Agreement and consummate the transactions contemplated
         hereby. The execution, delivery, and performance of this Agreement by
         CHC and the consummation by CHC of the transactions contemplated
         herein, including the Merger, have been duly and validly authorized by
         all necessary corporate action in respect thereof on the part of CHC,
         subject to the approval of this Agreement by its shareholders as
         contemplated by Section 8.1 of this Agreement. Subject to such
         requisite shareholder approval (and assuming due authorization,
         execution and delivery by FNB and Southwest) and to such Consents of
         Regulatory Authorities as required by applicable law, this Agreement
         represents a legal, valid, and binding obligation of CHC, enforceable
         against CHC in accordance with its terms (except in all cases as such
         enforceability may be limited by applicable bankruptcy, insolvency,
         reorganization, moratorium or similar Laws affecting the enforcement of
         creditors' rights generally and except that the availability of the
         equitable remedy of specific performance or injunctive relief is
         subject to the discretion of the court before which any proceeding may
         be brought). The CHC Board of Directors has received from Allen C.
         Ewing & Co. a letter dated as of the date of this Agreement to the
         effect that, in the opinion of such firm, the Exchange Ratio is fair,
         from a financial point of view, to the holders of CHC Common Shares.

             (b) Except as disclosed in Section 5.2 of the CHC Disclosure
         Memorandum, neither the execution and delivery of this Agreement by
         CHC, nor the consummation by CHC of the transactions contemplated
         hereby, nor compliance by CHC with any of the provisions hereof, will
         (i) conflict with or result in a breach of any provision of CHC's
         Articles of Incorporation or Bylaws, or, (ii) constitute or result in a
         Default under, or require any Consent pursuant to, or result in the
         creation of any Lien on any material Asset of any CHC Company under,
         any Contract or Permit of any CHC Company, where such Default or Lien,
         or any failure to obtain such Consent, is reasonably likely to have,
         individually or in the aggregate, a Material Adverse Effect on CHC and
         its Subsidiaries taken as a whole, or, (iii) subject to receipt of the
         requisite Consents referred to in Section 9.1(a), (b), and (c) of this
         Agreement, violate any Order, or to its Knowledge, any Law applicable
         to any CHC Company or any of their respective material Assets which
         will have a Material Adverse Effect on CHC and the Subsidiaries taken
         as a whole.

             (c) Other than in connection or compliance with the provisions of
         the Securities Laws, applicable state corporate and securities Laws,
         and rules of the Nasdaq, and other than Consents required from
         Regulatory Authorities, and other than notices to or filings with the
         Internal Revenue Service or the Pension Benefit Guaranty Corporation
         with respect to any employee benefit plans, or under the HSR Act, and
         other than Consents, filings, or notifications which, if not obtained
         or made, are not reasonably likely to have, individually or in the
         aggregate, a Material Adverse Effect on CHC and the Subsidiaries taken
         as a whole, no notice to, filing with, or Consent of, any public body
         or authority is necessary for the consummation by CHC of the Merger and
         the other transactions contemplated in this Agreement.

         5.3 Capital Stock.

             (a) The authorized capital stock of CHC consists of (i) 2,000,000
         CHC Common Shares, of which 580,795 shares are issued and outstanding
         as of the date of this Agreement and not more than 676,795 shares will
         be issued and outstanding at the Effective Time, and (ii) 2,000,000
         shares of preferred stock, par value $0.10 per share, none of which is
         issued and outstanding. All of the issued 



                                      A-7
   128

         and outstanding shares of capital stock of CHC are duly and validly
         issued and outstanding and are fully paid and nonassessable under the
         FBCA. None of the outstanding shares of capital stock of CHC has been
         issued in violation of any preemptive rights. CHC has reserved 100,000
         CHC Common Shares for issuance under the CHC Stock Plans, pursuant to
         which options and warrants to purchase not more than 96,000 CHC Common
         Shares are outstanding.

             (b) Except as set forth in Section 5.3(a) of this Agreement, or as
         provided pursuant to the Stock Option Agreement, there are no shares of
         capital stock or other equity securities of CHC outstanding and no
         outstanding Rights relating to the capital stock of CHC.

         5.4 CHC Subsidiaries. CHC has disclosed in Section 5.4 of the CHC
Disclosure Memorandum all of the CHC Subsidiaries as of the date of this
Agreement. Except as disclosed in Section 5.4 of the CHC Disclosure Memorandum,
CHC or one of its Subsidiaries owns all of the issued and outstanding shares of
capital stock of each CHC Subsidiary. No equity securities of any CHC Subsidiary
are or may become required to be issued (other than to another CHC Company) by
reason of any Rights, and there are no Contracts by which any CHC Subsidiary is
bound to issue (other than to another CHC Company) additional shares of its
capital stock or Rights or by which any CHC Company is or may be bound to
transfer any shares of the capital stock of any CHC Subsidiary (other than to
another CHC Company). There are no Contracts relating to the rights of any CHC
Company to vote or to dispose of any shares of the capital stock of any CHC
Subsidiary. All of the shares of capital stock of each CHC Subsidiary held by a
CHC Company are fully paid and nonassessable under the applicable corporation
Law of the jurisdiction in which such Subsidiary is incorporated or organized
and, except as set forth in Section 5.4 of the CHC Disclosure Memorandum, are
owned by the CHC Company free and clear of any Lien. Each CHC Subsidiary is
either a bank or a corporation, and is duly organized, validly existing, and (as
to corporations) in good standing under the Laws of the jurisdiction in which it
is incorporated or organized, and has the corporate power and authority
necessary for it to own, lease, and operate its Assets and to carry on its
business as now conducted. Each CHC Subsidiary is duly qualified or licensed to
transact business as a foreign corporation in good standing in each jurisdiction
where the character of its Assets or the nature or conduct of its business
requires it to be so qualified or licensed, except for such jurisdictions in
which the failure to be so qualified or licensed is not reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect on CHC and its
Subsidiaries taken as a whole. Each CHC Subsidiary that is a depository
institution is an "insured institution" as defined in the Federal Deposit
Insurance Act and applicable regulations thereunder, and the deposits in which
are insured by the Bank Insurance Fund.

         5.5 Regulatory Filings; Financial Statements. CHC has made available
to FNB copies of the CHC Financial Statements and all management letters of its
outside independent certified public accountants relating to any audits
performed in connection with the preparation of the CHC Financial Statements.
Each of the CHC Financial Statements (including, in each case, any related
notes), including any CHC Financial Statements filed after the date of this
Agreement until the Effective Time, was prepared in accordance with GAAP applied
on a consistent basis throughout the periods involved (except as may be
indicated therein or in the notes to such financial statements), and fairly
present or will present the financial position of CHC at the respective dates
and the results of its operations and cash flows at and for the periods
indicated, except that the unaudited interim financial statements were or are
subject to normal and recurring year-end adjustments which were not or are not
expected to be material in amount, and except for the absence of certain
footnote information in the unaudited interim financial statements.

         5.6 Absence of Certain Changes or Events. Except as disclosed in
Section 5.6 of the CHC Disclosure Memorandum, since December 31, 1997, (i) there
have been no events, changes, or occurrences which have had, or are reasonably
likely to have, individually or in the aggregate, a Material Adverse Effect 



                                      A-8
   129

on CHC and its Subsidiaries taken as a whole, and (ii) the CHC Companies have
not taken any action, or failed to take any action, prior to the date of this
Agreement, which action or failure, if taken after the date of this Agreement,
would represent or result in a material breach or violation of any of the
material covenants and agreements of CHC provided in Article 7 of this
Agreement.

         5.7 Tax Matters.

             (a) All Tax Returns required to be filed by or on behalf of any of
         the CHC Companies have been timely filed or requests for extensions
         have been timely filed, granted, and have not expired for periods ended
         on or before December 31, 1997, except to the extent that all such
         failures to file, taken together, are not reasonably likely to have a
         Material Adverse Effect on CHC and its Subsidiaries taken as a whole,
         and to the Knowledge of CHC all Tax Returns filed are complete and
         accurate in all material respects. All Taxes shown on filed Tax Returns
         have been paid. There is no audit examination, deficiency, or refund
         Litigation with respect to any Taxes that is reasonably likely to
         result in a determination that would have, individually or in the
         aggregate, a Material Adverse Effect on CHC and its Subsidiaries taken
         as a whole, except as reserved against in the CHC Financial Statements
         delivered prior to the date of this Agreement or as disclosed in
         Section 5.7 of the CHC Disclosure Memorandum. All Taxes and other
         liabilities due with respect to completed and settled examinations or
         concluded Litigation have been paid, accrued, or provided for as
         disclosed in Section 5.7 of the CHC Disclosure Memorandum.

             (b) Except as disclosed in Section 5.7 of the CHC Disclosure
         Memorandum, none of the CHC Companies has executed an extension or
         waiver of any statute of limitations on the assessment or collection of
         any material Tax due that is currently in effect.

             (c) Except as disclosed in Section 5.7 of the CHC Disclosure
         Memorandum, adequate provision for any Taxes due or to become due for
         any of the CHC Companies for the period or periods through and
         including the date of the respective CHC Financial Statements has been
         made and is reflected on such CHC Financial Statements.

             (d) Deferred Taxes of the CHC Companies have been adequately
         provided for in the CHC Financial Statements.

             (e) To the Knowledge of CHC, each of the CHC Companies is in
         compliance with, and its records contain all information and documents
         (including properly completed Internal Revenue Service Forms W-9)
         necessary to comply with, all applicable information reporting and Tax
         withholding requirements under federal, state, and local Tax Laws, and
         such records identify with specificity all accounts subject to backup
         withholding under Section 3406 of the Internal Revenue Code, except for
         such instances of noncompliance and such omissions as are not
         reasonably likely to have, individually or in the aggregate, a Material
         Adverse Effect on CHC and its Subsidiaries taken as a whole and its
         Subsidiaries taken as a whole.

             (f) There are no Liens with respect to Taxes upon any of the assets
         of the CHC Companies, except for loans on the Subsidiaries books
         guaranteed in the normal course of business.

             (h) No CHC Company has filed any consent under Section 341(f) of
         the Internal Revenue Code concerning collapsible corporation.



                                      A-9
   130

             (i) All material elections with respect to Taxes affecting the CHC
         Companies as of the date of this Agreement have been or will be timely
         made as set forth in Section 5.7 of the CHC Disclosure Memorandum.
         After the date hereof, other than as set forth in Section 5.7 of the
         CHC Disclosure Memorandum, no election with respect to Taxes will be
         made without the prior written consent of FNB, which consent will not
         be unreasonably withheld.

         5.8 Assets. Except as disclosed in Section 5.8 of the CHC Disclosure
Memorandum, the CHC Companies have good and marketable title, free and clear of
all Liens (except for those Liens which are not likely to have a Material
Adverse Effect on CHC or its Subsidiaries taken as a whole), to all of their
respective material Assets, reflected in CHC Financial Statements as being owned
by CHC as of the date hereof. All material tangible properties used in the
businesses of the CHC Companies are in good condition, reasonable wear and tear
excepted, and are usable in the ordinary course of business consistent with
CHC's past practices. All Assets which are material to CHC's business on a
consolidated basis, held under leases or subleases by any of the CHC Companies,
are held under valid Contracts enforceable in accordance with their respective
terms (except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium, or other Laws affecting the enforcement
of creditors' rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceedings may be brought), and each such
Contract is in full force and effect. The CHC Companies currently maintain
insurance in amounts, scope, and coverage as disclosed in Section 5.8 of the CHC
Disclosure Memorandum. None of the CHC Companies has received written notice
from any insurance carrier that (i) such insurance will be canceled or that
coverage thereunder will be reduced or eliminated, or (ii) premium costs with
respect to such policies of insurance will be substantially increased. Except as
disclosed in Section 5.8 of the CHC Disclosure Memorandum, to the Knowledge of
CHC there are presently no occurrences giving rise to a claim under such
policies of insurance and no notices have been given by any CHC Company under
such policies.

         5.9 Environmental Matters.

             (a) To the Knowledge of CHC, except as disclosed in Section 5.9 of
         the CHC Disclosure Memorandum, each CHC Company, its Participation
         Facilities, and its Loan Properties are, and have been, in compliance
         with all Environmental Laws, except for violations which are not
         reasonably likely to have, a Material Adverse Effect on CHC and its
         Subsidiaries taken as a whole.

             (b) To the Knowledge of CHC, except as disclosed in Section 5.9 of
         the CHC Disclosure Memorandum, there is no Litigation pending or
         threatened before any court, governmental agency, or authority or other
         forum in which any CHC Company or any of its Loan Properties or
         Participation Facilities has been or, with respect to threatened
         Litigation, may be named as a defendant or potentially responsible
         party (i) for alleged noncompliance (including by any predecessor) with
         any Environmental Law or (ii) relating to the release into the
         environment of any Hazardous Material, whether or not occurring at, on,
         under, or involving any of its Loan Properties or Participation
         Facilities, except for such Litigation pending or threatened that is
         not reasonably likely to have, individually or in the aggregate, a
         Material Adverse Effect on CHC and its Subsidiaries taken as a whole.

             (c) To the Knowledge of CHC, except as disclosed in Section 5.9 of
         the CHC Disclosure Memorandum, there is no reasonable basis for any
         Litigation of a type described above in Section 5.9(b), except such as
         is not reasonably likely to have, individually or in the aggregate, a

             (d) To the Knowledge of CHC, except as disclosed in Section 5.9 of
         the CHC Disclosure Memorandum, during the period of (i) CHC's or any of
         its Subsidiaries' ownership or operation of any of their respective
         properties, (ii) CHC's or any of its Subsidiaries' participation in the
         management of any Participation Facility, or (iii) CHC's or any of its
         Subsidiaries' holding a security interest in a Loan Property, to the
         Knowledge of CHC there have been no releases of Hazardous Material in,
         on, under, or affecting any Participation Facility or Loan Property of
         a CHC Company, except such as are not reasonably likely to have,
         individually or in the aggregate, a Material Adverse Effect on CHC and
         its Subsidiaries taken as a whole.

         5.10 Compliance With Laws. CHC is duly registered as a bank holding
company under the BHC Act. Except as set forth in Section 5.10 of the CHC
Disclosure Memorandum, each CHC Company has in effect all Permits necessary for
it to own, lease, or operate its material Assets and to carry on its business as
now conducted, except for those Permits the absence of which are not reasonably
likely to have, individually or in the aggregate, a Material Adverse Effect on
CHC and its Subsidiaries taken as a whole. None of the CHC Companies is
presently in default under any such Permit, other than defaults which are not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on CHC and its Subsidiaries taken as a whole. Except as disclosed in
Section 5.10 of the CHC Disclosure Memorandum, none of the CHC Companies:

              (a) to the Knowledge of CHC is in violation of any Laws or Orders,
         applicable to its business or employees conducting its business, except

         taken as a whole; and

              (b) has received any written notification or communication from
         any agency or department of federal, state, or local government or any
         Regulatory Authority or the staff thereof (i) asserting that any CHC
         Company is not in substantial compliance with any of the Laws or Orders
         which such governmental authority or Regulatory Authority enforces,
         where such noncompliance is reasonably likely to have, individually or
         in the aggregate, a Material Adverse Effect on CHC and its Subsidiaries
         taken as a whole, (ii) threatening to revoke any Permits, the
         revocation of which is reasonably likely to have, a Material Adverse
         Effect on CHC and its Subsidiaries taken as a whole, or (iii) requiring
         any CHC Company to enter into or consent to the issuance of a cease and
         desist order, formal agreement, directive, commitment, or memorandum of
         understanding, or to adopt any Board resolution or similar undertaking,
         which restricts materially the conduct of its business, or in any
         manner relates to its capital adequacy, its credit or reserve policies,
         its management, or the payment of dividends.

         5.11 Labor Relations. No CHC Company is the subject of any Litigation
asserting that it or any other CHC Company has committed an unfair labor
practice (within the meaning of the National Labor Relations Act or comparable
state law) or seeking to compel it or any other CHC Company to bargain with any
labor organization as to wages or conditions of employment, nor is there any
strike or other labor dispute involving any CHC Company, pending or, to the
Knowledge of CHC, threatened, nor is there any activity involving any CHC
Company's employees seeking to certify a collective bargaining unit or engaging
in any other organization activity.

         5.12 Employee Benefit Plans.

              (a) CHC has disclosed in Section 5.12 of the CHC Disclosure
         Memorandum, and has delivered or made available to FNB prior to the
         execution of this Agreement copies or summaries in each case of, all
         material pension, retirement, profit-sharing, deferred compensation,
         stock option, employee stock ownership, severance pay, vacation, bonus,
         or other incentive plan, all other written employee programs,
         arrangements, or agreements, all medical, vision, dental, or other
         health plans, all life insurance plans, and all other employee benefit
         plans or fringe benefit plans, including "employee benefit plans" (as
         that term is defined in Section 3(3) of ERISA), currently adopted,
         maintained by, sponsored in whole or in part by, or contributed to by
         CHC or any of its Subsidiaries for the benefit of employees, retirees,
         dependents, spouses, directors, independent contractors, or other
         beneficiaries and under which employees, retirees, dependents, spouses,
         directors, independent contractors, or other beneficiaries are eligible
         to participate (collectively, the "CHC Benefit Plans"). Any of the CHC
         Benefit Plans which is an "employee pension benefit plan" (as that term
         is defined in Section 3(2) of ERISA) is referred to herein as a "CHC
         ERISA Plan." No CHC Benefit Plan is or has been a multi-employer plan
         within the meaning of Section 3(37) of ERISA.

              (b) Except as disclosed in the CHC Disclosure Memorandum, all CHC
         Benefit Plans are in compliance in all material respects with the
         applicable terms of ERISA, the Internal Revenue Code, and any other
         applicable Laws, the breach or violation of which are reasonably likely
         to have, individually or in the aggregate, a Material Adverse Effect on
         CHC and its Subsidiaries on a consolidated basis.

              (c) Except as disclosed in Section 5.12 of the CHC Disclosure
         Memorandum, no CHC ERISA Plan which is a "defined benefit pension plan"
         (as defined in Section 4140 of the Internal Revenue Code) has any
         "unfunded current liability" (as that term is defined in Section
         302(d)(8)(A) of ERISA) and the present fair market value of the assets
         of any such plan exceeds the plan's "benefit liabilities" (as that term
         is defined in Section 4001(a)(16) of ERISA) when determined under
         actuarial factors that would apply if the plan terminated in accordance
         with all applicable legal requirements.

              (d) Except as disclosed in Section 5.12 of the CHC Disclosure
         Memorandum or otherwise provided by this Agreement, neither the
         execution and delivery of this Agreement nor the consummation of the
         transactions contemplated hereby will (i) result in any payment
         (including, without limitation, severance, unemployment compensation,
         golden parachute, or otherwise) becoming due to any director or any
         employee of CHC or any of its Subsidiaries from CHC or any of its
         Subsidiaries under any CHC Benefit Plan or otherwise, (ii) increase any
         benefits otherwise payable under any CHC Benefit Plan or (iii) result
         in any acceleration of the time of payment or vesting of any such
         benefits, where such payment, increase, or acceleration is reasonably
         likely to have, individually or in the aggregate, a Material Adverse
         Effect on CHC and its Subsidiaries on a consolidated basis.

         5.13 Material Contracts. Except as disclosed in Section 5.13 of the
CHC Disclosure Memorandum, CHC is not a party to or subject to the following:
(i) any employment, severance, termination, consulting, or retirement Contract
providing for aggregate payments to any Person in any calendar year in excess of
$50,000, (ii) any Contract relating to the borrowing of money by CHC or the
guarantee by CHC of any such obligation exceeding $50,000 (other than Contracts
evidencing deposit liabilities, purchases of federal funds, fully-secured
repurchase agreements, and Federal Home Loan Bank advances to depository
institution Subsidiaries, trade payables, and Contracts relating to borrowings
or guarantees made in the 



                                      A-12
   133

ordinary course of business), and (iii) any other material Contract or amendment
thereto as of the date of this Agreement not made in the ordinary course of
business to which CHC is a party or by which it is bound (together with all
Contracts referred to in Sections 5.8 and 5.12(a) of this Agreement, the "CHC
Contracts"). With respect to each CHC Contract and except as disclosed in
Section 5.13 of the CHC Disclosure Memorandum: (i) the Contract is in full force
and effect; (ii) CHC is not in default thereunder, other than defaults which are
not reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on CHC and its Subsidiaries taken as a whole; (iii) CHC has not
repudiated or waived any material provision of any such CHC Contract; and (iv)
no other party to any such CHC Contract is, to the Knowledge of CHC, in default
in any material respect, other than defaults which are not reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect on CHC and its
Subsidiaries taken as a whole, or has repudiated or waived any material
provision thereunder. Except for Federal Home Loan Bank advances, all of the
indebtedness of CHC for money borrowed is prepayable at any time by CHC without
penalty or premium. CHC's obligation in connection with the retirement of its
former Chief Executive Officer, C. David Carley, Jr., is fully funded as
described in Section 5.13 of the CHC Disclosure Memorandum.

         5.14 Legal Proceedings. Except as disclosed in Section 5.14 of the CHC
Disclosure Memorandum, there is no Litigation instituted or pending, or, to the
Knowledge of CHC, threatened (or unasserted but considered probable of assertion
and which if asserted would have at least a reasonable probability of an
unfavorable outcome) against any CHC Company, or against any Asset, employee
benefit plan, interest, or right of any of them, that is reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect on CHC and its
Subsidiaries taken as a whole, nor are there any Orders of any Regulatory
Authorities, other governmental authorities, or arbitrators outstanding against
any CHC Company, that are reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on CHC and its Subsidiaries taken as a
whole. Section 5.14 of the CHC Disclosure Memorandum includes a summary report
of all Litigation as of the date of this Agreement to which any CHC Company is a
party and which names a CHC Company as a defendant or cross-defendant and where
the estimated maximum exposure is $25,000 or more.

         5.15 Reports. Since January 1, 1995, or the date of organization if
later, each CHC Company has timely filed all reports and statements, together
with any amendments required to be made with respect thereto, that it was
required to file, which failure to file or amend is reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect of CHC and its
Subsidiaries taken as a whole, with any Regulatory Authorities. As of their
respective dates, each of such reports and documents, including the financial
statements, exhibits, and schedules thereto, complied in all material respects
with all applicable Laws enforced by the Florida Department of Banking and
Finance, the Federal Deposit Insurance Corporation, or the Board of Governors of
the Federal Reserve System. As of its respective date, each such report and
document did not, in all material respects, contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements made therein, in light of the circumstances
under which they were made, not misleading, which untrue statement of a material
fact or omission to state a material fact is likely to have, individually or in
the aggregate, a Material Adverse Effect on CHC and its Subsidiaries taken as a
whole.

         5.16 Statements True and Correct. None of the information supplied or
to be supplied by any CHC Company or any Affiliate thereof for inclusion in the
Registration Statement to be filed by FNB with the SEC will, when the
Registration Statement becomes effective, be false or misleading with respect to
any material fact, or omit to state any material fact necessary to make the
statements therein not misleading. None of the information supplied or to be
supplied by any CHC Company or any Affiliate thereof for inclusion in the Proxy
Statement to be mailed to CHC's shareholders in connection with the
Shareholders' Meeting, and any other documents to be filed by a CHC Company or
any Affiliate thereof with the SEC or any other Regulatory Authority in
connection with the transactions contemplated hereby, will, at the



                                      A-13
   134

respective time such documents are filed, and with respect to the Proxy
Statement, when first mailed to the shareholders of CHC, be false or misleading
with respect to any material fact, or omit to state any material fact necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading, or, in the case of the Proxy Statement or any
amendment thereof or supplement thereto, at the time of the Shareholders'
Meeting, be false or misleading with respect to any material fact, or omit to
state any material fact necessary to correct any statement in any earlier
communication with respect to the solicitation of any proxy for the
Shareholders' Meeting. All documents that any CHC Company or any Affiliate
thereof is responsible for filing with any Regulatory Authority in connection
with the transactions contemplated hereby will comply as to form in all material
respects with the provisions of applicable Law.

         5.17 Accounting, Tax and Regulatory Matters. To the knowledge of CHC,
except for the stock purchase program commenced on December 22, 1997, neither
CHC nor any Affiliate thereof has taken or agreed to take any action which
would, or has any Knowledge of any fact or circumstance that is reasonably
likely to (i) prevent the transactions contemplated hereby, including the
Merger, from qualifying for pooling-of-interests accounting treatment or as a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code, or (ii) materially impede or delay receipt of any Consents of Regulatory
Authorities referred to in Section 9.1(b) of this Agreement or result in the
imposition of a condition or restriction of the type referred to in the last
sentence of such Section.

         5.18 State Takeover Laws. Each CHC Company has taken all necessary
action to exempt the transactions contemplated by this Agreement from the
provisions of Sections 607.0901 through 607.0903, inclusive, of the FBCA
(collectively, "Takeover Laws").

         5.19 Derivatives Contracts. Except as disclosed in Section 5.19 of the
CHC Disclosure Memorandum, neither CHC nor any of its Subsidiaries is a party to
or has agreed to enter into an exchange-traded or over-the-counter swap,
forward, future, option, cap, floor, or collar financial contract, or any other
interest rate or foreign currency protection contract not included on its
balance sheet which is a financial derivative contract (including various
combinations thereof) (each a "Derivatives Contract").

         6.2 Authority; No Breach By Agreement.

             (a) Each of FNB and Southwest has the corporate power and authority

         This Agreement represents a legal, valid, and binding obligation of FNB
         and Southwest, enforceable against FNB and Southwest in accordance with
         its terms (except in all cases as such enforceability may be limited by
         applicable bankruptcy, insolvency, reorganization, moratorium, or
         similar Laws affecting the enforcement of creditors' rights generally
         and except that the availability of the equitable remedy of specific
         performance or injunctive relief is subject to the discretion of the
         court before which any proceeding may be brought).

             (b) Neither the execution and delivery of this Agreement by FNB or
         Southwest, nor the consummation by FNB or Southwest of the transactions
         contemplated hereby, nor compliance by FNB or Southwest with any of the
         provisions hereof, will (i) conflict with or result in a breach of any
         provision of the Articles of Incorporation or Bylaws of FNB or
         Southwest, or (ii) constitute or result in a Default under, or require
         any Consent pursuant to, or result in the creation of any Lien on any
         Asset of any FNB Company or Southwest under, any Contract or Permit of

         failure to obtain such Consent, is reasonably likely to have,
         individually or in the aggregate, a Material Adverse Effect on FNB or
         Southwest, or, (iii) subject to receipt of the requisite Consents
         referred to in Section 9.1(b) of this Agreement, violate any Law or
         Order applicable to any FNB Company or Southwest or any of their
         respective material Assets.

             (c) Other than in connection or compliance with the provisions of

         Revenue Service or the Pension Benefit Guaranty Corporation with
         respect to any employee benefit plans, or under the HSR Act, and other
         than Consents, filings, or notifications which, if not obtained or
         made, are not reasonably likely to have, individually or in the
         aggregate, a Material Adverse Effect on FNB and Southwest, no notice
         to, filing with, or Consent of, any public body or authority is
         necessary for the consummation by FNB and Southwest of the Merger and
         the other transactions contemplated in this Agreement.

         6.3 Capital Stock. The authorized capital stock of FNB consists of (i)
100,000,000 shares of FNB Common Stock, of which 15,190,367 shares were issued

FNB Preferred Stock, of which 274,947 shares were issued and outstanding as of
the date of this Agreement ("FNB Capital Stock"). All of the issued and
outstanding shares of FNB Capital Stock are, and all of the FNB Common Stock to
be issued in exchange for CHC Common Shares upon consummation of the Merger will
be authorized and reserved for issuance prior to the Effective Time and, when
issued in accordance with the terms of this Agreement, will be, duly and validly
issued and 



                                      A-15
   136

outstanding and fully paid and nonassessable under the PBCL. None of the

Disclosure Memorandum, the list of Subsidiaries of FNB filed by FNB with its
most recent FNB Report on Form 10-K for the fiscal year ended December 31, 1997,
is a true and complete list of all of the FNB Subsidiaries as of the date of
this Agreement. Except as disclosed in Section 6.4 of the FNB Disclosure
Memorandum, FNB or one of its Subsidiaries owns all of the issued and
outstanding shares of capital stock of each FNB Subsidiary. No equity securities
of any FNB Subsidiary are or may become required to be issued (other than to
another FNB Company) by reason of any Rights, and there are no Contracts by
which any FNB Subsidiary is bound to issue (other than to another FNB Company)
additional shares of its capital stock or Rights or by which any FNB Company is
or may be bound to transfer any shares of the capital stock of any FNB
Subsidiary (other than to another FNB Company). There are no Contracts relating
to the rights of any FNB Company to vote or to dispose of any shares of the
capital stock of any FNB Subsidiary. All of the shares of capital stock of each
FNB Subsidiary held by a FNB Company are fully paid and nonassessable under the
applicable corporation Law of the jurisdiction in which such Subsidiary is
incorporated or organized (except, in the case of Subsidiaries that are national
banks, for the assessment contemplated by 12 U.S.C. ss. 55), and are owned by
the FNB Company free and clear of any Lien. Each FNB Subsidiary is either a bank
or a corporation, and is duly organized, validly existing, and (as to
corporations) in good standing under the Laws of the jurisdiction in which it is
incorporated or organized, and has the corporate power and authority necessary
for it to own, lease, and operate its Assets and to carry on its business as now
conducted. Each FNB Subsidiary is duly qualified or licensed to transact
business as a foreign corporation and is in good standing in each jurisdiction
where the character of its Assets or the nature or conduct of its business
requires it to be so qualified or licensed, except for such jurisdictions in
which the failure to be so qualified or licensed is not reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect on FNB. Each
FNB Subsidiary that is a depository institution is an "insured institution" as
defined in the Federal Deposit Insurance Act and applicable regulations
thereunder, and the deposits in which are insured by the Bank Insurance Fund or

         copies of all forms, reports, and documents required to be filed by FNB
         with the SEC since January 1, 1994 (collectively, the "FNB SEC
         Reports"). The FNB SEC Reports (i) at the time filed, complied in all
         material respects with the applicable requirements of the 1933 Act and
         the 1934 Act, as the case may be, and (ii) did not at the time they
         were filed (or if amended or superseded by a filing prior to the date
         of this Agreement, then on the date of such filing) contain any untrue
         statement of a material fact or omit to state a material fact required
         to be stated in such FNB SEC Reports or necessary in order to make the
         statements in such FNB SEC Reports, in light of the circumstances under
         which they were made, not misleading. Except for FNB Subsidiaries that
         are registered as brokers, dealers, investment advisers, or associated
         persons thereof, none of the FNB Subsidiaries is required to file any
         forms, reports or other documents with the SEC.

             (b) Each of the FNB Financial Statements (including, in each case,
         any related notes) contained in the FNB SEC Reports, including any FNB
         SEC Reports filed after the date of this Agreement until the Effective
         Time, complied, and each FNB SEC Report filed after the date of this
         Agreement until the Effective Time will comply, as to form in all
         material respects with the 



                                      A-16
   137

         applicable published rules and regulations of the SEC with respect
         thereto, was or will be prepared in accordance with GAAP applied on a
         consistent basis throughout the periods involved (except as may be
         indicated in the notes to such financial statements or, in the case of
         unaudited statements, as permitted by Form 10-Q of the SEC), and fairly
         presented the consolidated financial position of FNB and its
         Subsidiaries as at the respective dates and the consolidated results of
         its operations and cash flows for the periods indicated, except that
         the unaudited interim financial statements were or are subject to
         normal and recurring year-end adjustments which were not or are not
         expected to be material in amount.

         6.6 Absence of Certain Changes or Events. Since December 31, 1997, (i)
there have been no events, changes, or occurrences which have had, or are
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on FNB, and (ii) the FNB Companies have not taken any action, or failed
to take any action, prior to the date of this Agreement, which action or
failure, if taken after the date of this Agreement, would represent or result in
a material breach or violation of any of the covenants and agreements of FNB or
Southwest provided in Articles 7 or 8 of this Agreement.

         6.7 Tax Matters.

             (a) All Tax Returns required to be filed by or on behalf of any of
         the FNB Companies have been timely filed or requests for extensions
         have been timely filed, granted, and have not expired for periods ended
         on or before December 31, 1997, and on or before the date of the most
         recent fiscal year end immediately preceding the Effective Time, except
         to the extent that all such failures to file, taken together, are not
         reasonably likely to have a Material Adverse Effect on FNB, and all Tax
         Returns filed are complete and accurate in all material respects. All
         Taxes shown on filed Tax Returns have been paid. There is no audit
         examination, deficiency, or refund Litigation with respect to any Taxes
         that is reasonably likely to result in a determination that would have,
         individually or in the aggregate, a Material Adverse Effect on FNB,
         except as reserved against in the FNB Financial Statements delivered
         prior to the date of this Agreement. All Taxes and other liabilities
         due with respect to completed and settled examinations or concluded
         Litigation have been paid.

             (b) Adequate provision for any Taxes due or to become due for any
         of the FNB Companies for the period or periods through and including
         the date of the respective FNB Financial Statements has been made and
         is reflected on such FNB Financial Statements.

             (c) Deferred Taxes of the FNB Companies have been adequately
         provided for in the FNB Financial Statements.

             (d) To the Knowledge of FNB, each of the FNB Companies is in
         compliance with, and its records contain all information and documents
         (including properly completed Internal Revenue Service Forms W-9)
         necessary to comply with, all applicable information reporting and Tax
         withholding requirements under federal, state, and local Tax Laws, and
         such records identify with specificity all accounts subject to backup
         withholding under Section 3406 of the Internal Revenue Code, except for
         such instances of noncompliance and such omissions as are not
         reasonably likely to have, individually or in the aggregate, a Material
         Adverse Effect on FNB.

         6.8 Compliance With Laws. Both FNB and Southwest are duly registered
as a bank holding company under the BHC Act. Each FNB Company has in effect all
Permits necessary for it to own, lease, or operate its material Assets and to
carry on its business as now conducted, except for those Permits the absence of
which are not reasonably likely to have, individually or in the aggregate, a
Material Adverse 



                                      A-17
   138

Effect on FNB. None of the FNB Companies is presently in Default under or in
violation of any such Permit, other than Defaults which are not reasonably
likely to have, individually or in the aggregate, a Material Adverse Effect on
FNB. No FNB Company:

             (a) is in violation of any Laws, Orders, or Permits applicable to
         its business or employees conducting its business, except for
         violations which are not reasonably likely to have, individually or in
         the aggregate, a Material Adverse Effect on FNB; and

             (b) has received any notification or communication from any agency
         or department of federal, state, or local government or any Regulatory
         Authority or the staff thereof (i) asserting that any FNB Company is
         not in compliance with any of the Laws or Orders which such
         governmental authority or Regulatory Authority enforces, where such
         noncompliance is reasonably likely to have, individually or in the
         aggregate, a Material Adverse Effect on FNB, (ii) threatening to revoke
         any Permits, the revocation of which is reasonably likely to have,
         individually or in the aggregate, a Material Adverse Effect on FNB, or
         (iii) requiring any FNB Company to enter into or consent to the
         issuance of a cease and desist order, formal agreement, directive,
         commitment, or memorandum of understanding, or to adopt any board
         resolution or similar undertaking, which restricts materially the
         conduct of its business, or in any manner relates to its capital
         adequacy, its credit or reserve policies, its management or the payment
         of dividends.

         6.9 Assets. Except as disclosed in Section 6.9 of the FNB Disclosure
Memorandum, the FNB Companies have good and marketable title, free and clear of
all Liens (except for those Liens which are not likely to have a Material
Adverse Effect on FNB or its Subsidiaries taken as a whole), to all of their
respective material Assets, reflected in FNB Financial Statements as being owned
by FNB as of the date hereof. All material tangible properties used in the
businesses of the FNB Companies are in good condition, reasonable wear and tear
excepted, and are usable in the ordinary course of business consistent with
FNB's past practices. All Assets which are material to FNB's business on a
consolidated basis, held under leases or subleases by any of the FNB Companies,
are held under valid Contracts enforceable in accordance with their respective
terms (except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium, or other Laws affecting the enforcement
of creditors' rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceedings may be brought), and each such
Contract is in full force and effect. The FNB Companies currently maintain
insurance in amounts, scope, and coverage as disclosed in Section 6.9 of the FNB
Disclosure Memorandum. None of the FNB Companies has received written notice
from any insurance carrier that (i) such insurance will be canceled or that
coverage thereunder will be reduced or eliminated, or (ii) premium costs with
respect to such policies of insurance will be substantially increased. Except as
disclosed in Section 6.9 of the FNB Disclosure Memorandum, to the Knowledge of
FNB there are presently no occurrences giving rise to a claim under such
policies of insurance and no notices have been given by any FNB Company under
such policies.

         6.10 Legal Proceedings. Except as disclosed in Section 6.10 of the FNB
Disclosure Memorandum, there is no Litigation instituted or pending, or, to the
Knowledge of FNB, threatened (or unasserted but considered probable of assertion
and which if asserted would have at least a reasonable probability of an
unfavorable outcome) against any FNB Company, or against any Asset, interest, or
right of any of them, that is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on FNB, nor are there any Orders of any
Regulatory Authorities, other governmental authorities, or arbitrators
outstanding against any FNB Company, that are reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on FNB.



                                      A-18
   139

         6.11 Reports. Since January 1, 1995, or the date of organization if
later, each FNB Company has filed all reports and statements, together with any
amendments required to be made with respect thereto, that it was required to
file with Regulatory Authorities (except, in the case of state securities
authorities, failures to file which are not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on FNB). As of their
respective dates, each of such reports and documents, including the financial
statements, exhibits, and schedules thereto, complied in all material respects
with all applicable Laws. As of its respective date, each such report and
document did not, in all material respects, contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements made therein, in light of the circumstances
under which they were made, not misleading.

         6.12 Statements True and Correct. None of the information supplied or
to be supplied by any FNB Company or any Affiliate thereof for inclusion in the
Registration Statement to be filed by FNB with the SEC, will, when the
Registration Statement becomes effective, be false or misleading with respect to
any material fact, or omit to state any material fact necessary to make the
statements therein not misleading. None of the information supplied or to be
supplied by any FNB Company or any Affiliate thereof for inclusion in the Proxy
Statement to be mailed to CHC's shareholders in connection with the
Shareholders' Meeting, and any other documents to be filed by any FNB Company or
any Affiliate thereof with the SEC or any other Regulatory Authority in
connection with the transactions contemplated hereby, will, at the respective
time such documents are filed, and with respect to the Proxy Statement, when
first mailed to the shareholders of CHC, be false or misleading with respect to
any material fact, or omit to state any material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or, in the case of the Proxy Statement or any amendment thereof
or supplement thereto, at the time of the Shareholders' Meeting, be false or
misleading with respect to any material fact, or omit to state any material fact
necessary to correct any statement in any earlier communication with respect to
the solicitation of any proxy for the Shareholders' Meeting. All documents that
any FNB Company or any Affiliate thereof is responsible for filing with any
Regulatory Authority in connection with the transactions contemplated hereby
will comply as to form in all material respects with the provisions of
applicable Law.

         6.13 Accounting, Tax and Regulatory Matters. No FNB Company or any
Affiliate thereof has taken or agreed to take any action or has any Knowledge of
any fact or circumstance that is reasonably likely to (i) prevent the
transactions contemplated hereby, including the Merger, from qualifying as a
reorganization within the meaning of Section 368(a)(2)(D) of the Internal
Revenue Code, or (ii) materially impede or delay receipt of any Consents of
Regulatory Authorities referred to in Section 9.1(b) of this Agreement or result
in the imposition of a condition or restriction of the type referred to in the
last sentence of such Section.

         6.14 Environmental Matters.

              (a) To the Knowledge of FNB, except as disclosed in Section 6.14
         of the FNB Disclosure Memorandum, each FNB Company, its Participation
         Facilities, and its Loan Properties are, and have been, in compliance
         with all Environmental Laws, except for violations which are not
         reasonably likely to have, individually or in the aggregate, a Material
         Adverse Effect on FNB.

              (b) Except as disclosed in Section 6.14 of the FNB Disclosure
         Memorandum, there is no Litigation pending, or, to the Knowledge of
         FNB, threatened before any court, governmental agency, or authority or
         other forum in which any FNB Company or any of its Loan Properties or
         Participation Facilities (or any FNB Company in respect of any such
         Loan Property or Participation Facility) has been or, with respect to
         threatened Litigation, may be named as a defendant or potentially
         responsible party (i) for alleged noncompliance (including by any
         predecessor) with any 



                                      A-19
   140

         Environmental Law or (ii) relating to the release into the environment
         of any Hazardous Material, whether or not occurring at, on, under, or
         involving any of its Loan Properties or Participation Facilities,
         except for such Litigation pending or threatened that is not reasonably
         likely to have, individually or in the aggregate, a Material Adverse
         Effect on FNB.

              (c) To the Knowledge of FNB, except as disclosed in Section 6.14
         of the FNB Disclosure Memorandum, there is no reasonable basis for any
         Litigation of a type described above in Section 6.14(b), except such as
         is not reasonably likely to have, individually or in the aggregate, a
         Material Adverse Effect on FNB.

              (d) To the Knowledge of FNB, except as disclosed in Section 6.14
         of the FNB Disclosure Memorandum, during the period of (i) FNB's or any
         of its Subsidiaries' ownership or operation of any of their respective
         properties, (ii) FNB's or any of its Subsidiaries' participation in the
         management of any Participation Facility, or (iii) FNB's or any of its
         Subsidiaries' holding a security interest in a Loan Property, to the
         Knowledge of FNB there have been no releases of Hazardous Material in,
         on, under, or affecting any Participation Facility or Loan Property of
         a FNB Company, except such as are not reasonably likely to have,
         individually or in the aggregate, a Material Adverse Effect on FNB.

         6.15 Derivatives Contracts. Neither FNB nor any of its Subsidiaries is
a party to or has agreed to enter into a Derivatives Contract, except for those
Derivatives Contracts set forth in Section 6.15 of the FNB Disclosure
Memorandum.

         6.16 Outstanding CHC Common Stock. As of the date of this Agreement,
FNB Companies do not beneficially own any shares of CHC Common Stock for their
own accounts (not including those held in a fiduciary or trust capacity for, or
on behalf of, unaffiliated third parties). During the term of this Agreement, no
FNB Company, shall purchase or otherwise acquire beneficial ownership of any
additional CHC Common Stock except pursuant to the terms of this Agreement.

         6.17 Material Contracts. All material Contracts to which FNB is a party
and which are required to be filed as exhibits to FNB SEC Reports have been so
filed and, except as disclosed in Section 6.17 of the FNB Disclosure Memorandum,
as of the date of this Agreement, to the Knowledge of FNB neither FNB nor any of
the FNB Companies is a party to any Contract or amendment thereto that would be
required to be filed as an exhibit to a Form 10-K filed by FNB with the SEC
except for the fact that no such Form 10-K is presently required to be filed
with the SEC as of the date hereof.

this Agreement) of the chief executive officer, president, chief financial
officer, or any executive vice president or duly authorized designee of FNB:

         Person (except those who have received a commitment for a loan or
         extension of credit prior to the date of this Agreement) in excess of
         $250,000 (in either case FNB shall object thereto within two business
         days, and the failure to provide a written objection within two
         business days shall be deemed as the approval of FNB to make such loan
         or extend such credit); or

         any shares, of the capital stock of CHC, or make, declare, or pay any
         dividend or make any other distribution in respect of CHC's capital

         stock of any CHC Company, or any stock appreciation rights, or any
         option, warrant, conversion, or other right to acquire any such stock,
         or any security convertible into any such stock; or

             (f) adjust, split, combine, or reclassify any capital stock of any
         CHC Company or issue or authorize the issuance of any other securities

         employees or officers of any CHC Company, except in accordance with

         CHC and any Person (unless such amendment is required by Law) that CHC
         does not have the unconditional right to terminate without Liability
         (other than Liability for services already rendered), at any time on or
         after the Effective Time; or

         7.3 Covenants of FNB. From the date of this Agreement until the
earlier of the Effective Time or the termination of this Agreement, FNB
covenants and agrees that it shall (i) continue to conduct its business and the
business of FNB Subsidiaries in a manner designed in its reasonable judgment, to
enhance the long-term value of the FNB Common Stock and the business prospects
of the FNB Companies, and (ii) take no action which would (a) materially
adversely affect the ability of any Party to obtain any Consents required for
the transactions contemplated hereby without imposition of a condition or
restriction of the type referred to in the last sentence of Section 9.1(b) of
this Agreement, or (b) materially adversely affect the ability of any Party to
perform its covenants and agreements under this Agreement; provided, that the
foregoing shall not prevent any FNB Company from discontinuing or disposing of
any of its Assets or business if such action is, in the judgment of FNB,
desirable in the conduct of the business of FNB and its Subsidiaries. FNB
further covenants and agrees that it will not, without the prior written consent
of the Chairman and Chief Executive Officer of CHC, which consent shall not be
unreasonably withheld, amend the Articles of Incorporation or Bylaws of FNB, in
each case in any manner adverse to the holders of CHC Common Stock.

of the CHC Disclosure Memorandum, each Party agrees to give written notice
promptly to the other Party upon becoming aware of the occurrence or impending
occurrence of any event or circumstance relating to it or any of its
Subsidiaries which (i) is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on it or (ii) would cause or constitute a
material breach of any of its representations, warranties, or covenants
contained herein, and to use its reasonable best efforts to prevent or promptly
to remedy the same.

         7.5 Reports. Each Party and their respective Subsidiaries shall file
all reports required to be filed by each of them with Regulatory Authorities
between the date of this Agreement and the Effective Time and shall deliver to
the other Party copies of all such reports promptly after the same are filed. If
financial statements are contained in any such reports filed with the SEC, such
financial statements will fairly present the consolidated financial position of
the entity filing such statements as of the dates indicated and the consolidated
results of operations, changes in shareholders' equity, and cash flows for the
periods then ended in accordance with GAAP (subject in the case of interim
financial statements to normal recurring year-end adjustments that are not
material and except for the absence of certain footnote information in the
unaudited



                                      A-23
   144

financial statements). As of their respective dates, such reports filed with the
SEC will comply in all material respects with the Securities Laws and will not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Any financial statements contained in any other reports to another
Regulatory Authority shall be prepared in accordance with Laws applicable to
such reports.

FNB may reasonably request in connection with such action. CHC shall call a
Shareholders' Meeting, to be held on a date that is determined by the Parties to

reasonable best efforts to obtain such shareholders' approval.

         8.2 Applications. FNB shall promptly prepare and file, and CHC shall
cooperate in the preparation and, where appropriate, filing of, applications
with all Regulatory Authorities having jurisdiction over the transactions
contemplated by this Agreement seeking the requisite Consents necessary to
consummate the transactions contemplated by this Agreement and thereafter use
its reasonable best efforts to cause the Merger to be consummated as
expeditiously as possible. Further, FNB shall, prior to the Closing, prepare and
file with the National Association of Securities Dealers the required documents
and make payment of the required fees for the shares of FNB Common Stock to be

the Closing.

         8.4 Agreement As To Efforts To Consummate. Subject to the terms and
conditions of this Agreement, each Party agrees to use, and to cause its
Subsidiaries to use, its reasonable best efforts to take, or cause to be taken,
all actions, and to do, or cause to be done, all things necessary, proper, or
advisable under applicable Laws to consummate and make effective, as soon as
practicable after the date of this Agreement, the transactions contemplated by
this Agreement, including the use of their respective reasonable



                                      A-24
   145

best efforts to lift or rescind any Order adversely affecting its ability to
consummate the transactions contemplated herein and to cause to be satisfied the
conditions referred to in Article 9 of this Agreement; provided, that nothing
herein shall preclude either Party from exercising its rights under this
Agreement. Each Party shall use, and shall cause each of its Subsidiaries to
use, its reasonable best efforts to obtain all Permits and Consents of all third
parties and Regulatory Authorities necessary or desirable for the consummation
of the transactions contemplated by this Agreement.

         8.5 Access to Information; Confidentiality.

             (a) From the date hereof to the Effective Time or termination
         pursuant to Article 10 of this Agreement, upon reasonable notice and
         subject to applicable Laws, FNB and CHC shall afford each other, and
         each other's accountants, counsel, and other representatives, during
         normal working hours for the period of time prior to the Effective Time
         or termination of this Agreement pursuant to Article 10 hereof,
         reasonable access to all of its and its Subsidiaries' properties,
         books, contracts, commitments, and records and, during such period,
         each shall furnish promptly to the other Party (i) a copy of each
         report, schedule, and other document filed or received by it or any of
         its Subsidiaries during such period pursuant to the requirements of the
         Securities Laws, (ii) a copy of all filings made with any Regulatory
         Authorities or other governmental entities in connection with the
         transactions contemplated by this Agreement and all written
         communications received from such Regulatory Authorities and
         governmental entities related thereto, and (iii) all other information
         concerning FNB or FNB's Subsidiaries' business, properties and
         personnel as CHC may reasonably request, including reports of condition
         filed with Regulatory Authorities. In this regard, without limiting the
         generality of the foregoing, FNB and its Subsidiaries and Affiliates
         shall notify CHC promptly upon the receipt by it of any comments from
         the SEC, or its staff, and of any requests by the SEC for amendments or
         supplements to the Registration Statement or for additional information
         and will supply CHC with copies of all correspondence between it and
         its representatives, on the one hand, and the SEC or the members of its
         staff or any other government official, on the other hand, with respect
         to the Registration Statement. Each Party hereto shall, and shall cause
         its advisors and representatives to (x) conduct its investigation in
         such a manner which will not unreasonably interfere with the normal
         operations, customers or employee relations of the other and shall be
         in accordance with procedures established by the Parties having the due
         regard for the foregoing, and (y) refrain from using for any purposes
         other than as set forth in this Agreement, and shall treat as
         confidential, all information obtained by each hereunder or in
         connection herewith and not otherwise known to them prior to the
         Effective Time.

             (b) FNB, the FNB Companies and their Affiliates will hold, and will
         use their best efforts to cause their officers, directors, employees,
         consultants, advisors, representatives, and agents to hold, in
         confidence, unless compelled by judicial or other legal process, all
         confidential documents and information concerning CHC furnished to FNB,
         any FNB Company, or their Affiliates in connection with the
         transactions contemplated by this Agreement, including information
         provided in accordance with this Section 8.5, except to the extent that
         such information can clearly be demonstrated by FNB to have been (i)
         previously known on a nonconfidential basis by FNB, (ii) in the public
         domain other than as a result of disclosure by FNB, any FNB Company, or
         any of their Affiliates, or (iii) later lawfully acquired by FNB from
         sources other than CHC; provided, however, that FNB may disclose such
         information to its officers, directors, employees, consultants,
         advisors, representatives, and agents in connection with the
         transactions contemplated by this Agreement only to the extent that
         such Persons who, in FNB's reasonable judgment, need to know such
         information for the purpose of evaluating CHC (provided that such
         Persons shall be informed of the confidential nature of such
         information and shall agree to be bound by the terms of this provision)
         and, in any event, such 



                                      A-25
   146

         disclosures shall be made only to the extent necessary for such
         purposes. If this Agreement is terminated in accordance with Article 10
         hereof, FNB, the FNB Companies and their Affiliates shall maintain the
         confidence of such information and will, and will use their best
         efforts to cause its officers, directors, employees, consultants,
         advisors, representatives, and agents to, return to CHC all documents
         and other materials, and all copies made thereof, obtained by FNB, any
         FNB Company, or any of their Affiliates in connection with this
         Agreement that are subject to this Section 8.5.

         (c) CHC and its Affiliates will hold, and will use their best efforts
to cause their officers, directors, employees, consultants, advisors,
representatives, and agents to hold, in confidence, unless compelled by judicial
or other legal process, all confidential documents and information concerning
FNB furnished to CHC or its Affiliates in connection with the transactions
contemplated by this Agreement, including information provided in accordance
with this Section 8.5, except to the extent that such information can clearly be
demonstrated by CHC to have been (i) previously known on a nonconfidential basis
by CHC, (ii) in the public domain other than as a result of disclosure by CHC or
any of its Affiliates, or (iii) later lawfully acquired by CHC from sources
other than FNB; provided, however, that CHC may disclose such information to its
officers, directors, employees, consultants, advisors, representatives, and
agents in connection with the transactions contemplated by this Agreement only
to the extent that such Persons who, in CHC's reasonable judgment, need to know
such information for the purpose of evaluating FNB (provided that such Persons
shall be informed of the confidential nature of such information and shall agree
to be bound by the terms of this provision) and, in any event, such disclosures
shall be made only to the extent necessary for such purposes. If this Agreement
is terminated in accordance with Article 10 hereof, CHC and its Affiliates shall
maintain the confidence of such information and will, and will use their best
efforts to cause its officers, directors, employees, consultants, advisors,
representatives, and agents to, return to FNB all documents and other materials,
and all copies made thereof, obtained by CHC or any of its Affiliates in
connection with this Agreement that are subject to this Section 8.5.

         8.6 Press Releases. Prior to the Effective Time, CHC and FNB shall
consult with each other as to the form and substance of any press release or
other public disclosure materially related to this Agreement or any other
transaction contemplated hereby; provided, that nothing in this Section 8.6
shall be deemed to prohibit any Party from making any disclosure which its
counsel deems necessary or advisable in order to satisfy such Party's disclosure
obligations imposed by Law.

         8.7 Current Information. During the period from the date of this
Agreement until the Effective Time or termination of this Agreement pursuant to
Article 10 hereof, each of CHC and FNB shall, and shall cause its
representatives to, confer on a regular and frequent basis with representatives
of the other. Each of CHC and FNB shall promptly notify the other of (i) any
material change in its business or operations, (ii) any material complaints,
investigations, or hearings (or communications indicating that the same may be
contemplated) of any Regulatory Authority, (iii) the institution or threat of
material Litigation involving such Party, or (iv) the occurrence or
nonoccurrence, of an event or condition, the occurrence, or nonoccurrence, of
which would be reasonably expected to cause any of such party's representations
or warranties set forth herein in any respect as of the Effective Time; and in
each case shall keep the other fully informed with respect thereto.

         8.8 Other Actions. No Party shall, or shall permit any of its
Subsidiaries, if any, to, take any action, except in every case as may be
required by applicable Law, that would or is intended to result in (i) any of
its representations and warranties set forth in this Agreement that are
qualified as to materiality being or becoming untrue, (ii) any of such
representations and warranties that are not so qualified become untrue in any
material manner having a Material Adverse Effect, (iii) any of the conditions
set forth in this 



                                      A-26
   147

Agreement not being satisfied or in a violation of any provision of this
Agreement, or (iv) adversely affecting the ability of any of them to obtain any
of the Consents or Permits from Regulatory Authorities (unless such action is
required by sound banking practice).

         8.9 No Solicitation. Except with respect to this Agreement and the
transactions contemplated hereby, from the date of this Agreement until the
Effective Time or termination pursuant to Article 10, no CHC Company nor any
Affiliate thereof, or any Representatives thereof retained by any CHC Company
shall directly or indirectly solicit any Acquisition Proposal by any Person.
Except to the extent necessary to comply with the fiduciary duties of CHC's
Board of Directors determined after consultation with counsel, no CHC Company
nor any Affiliate or Representative thereof shall furnish any nonpublic
information that it is not legally obligated to furnish or negotiate with
respect to, any Acquisition Proposal, but CHC may communicate information about
such an Acquisition Proposal to its shareholders if and to the extent that it is
required to do so in order to comply with its legal obligations as advised by
counsel. CHC shall promptly notify FNB orally and in writing in the event that
it receives any inquiry or proposal relating to any such transaction. CHC shall
(i) immediately cease and cause to be terminated any existing activities,
discussions, or negotiations with any Persons conducted heretofore with respect
to any of the foregoing, and (ii) direct and use its reasonable best efforts to
cause of all its Representatives not to engage in any of the foregoing.

         8.10 Certain Purchases. Except as contemplated in this Agreement, for a
period of three years after the date of this Agreement, and if this Agreement is
terminated as provided in Section 10.1 hereof, then for a period of three years
from the date of termination, FNB will not (and will ensure that the FNB
Subsidiaries and Affiliates will not), without the prior written approval of the
Board of Directors of CHC or any committee thereof: (i) directly purchase or
otherwise acquire, or enter into any agreement to purchase or otherwise acquire,
any equity securities of CHC, any warrants or options to purchase such equity
securities, any securities convertible into such equity securities, or any other
rights to acquire such equity securities, (ii) make or in any way participate
directly or indirectly in any "solicitation" of "proxies" (as such terms are
used in the proxy rules of the SEC), to vote any equity securities of CHC
(unless any third party shall then be engaged in such a solicitation and such
solicitation relates to a content for control of CHC and except that this clause
(ii) shall not apply to solicitations made by CHC), or (iii) make any public
request to waive any provision of this Section 8.10 or to permit any action
prohibited by this Section 8.10 to be taken. Notwithstanding the foregoing,
nothing in this Section 8.10 shall prohibit FNB from indirectly acquiring any
equity securities of CHC by acquiring through merger, consolidation or
otherwise, a financial institution which owns equity securities of CHC.

         8.11 Accounting and Tax Treatment. Each of the Parties undertakes and
agrees to use its reasonable best efforts to cause the Merger, and to take no
action which would cause the Merger not, to qualify for treatment as a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code for federal income tax purposes. FNB and CHC undertake and agree to use
their respective reasonable best efforts to cause the Merger, and to take no
action that would cause the Merger not, to qualify for pooling-of-interests
accounting treatment.

         8.12 State Takeover Laws. Each CHC Company shall take all necessary
steps to exempt the transactions contemplated by this Agreement from, or if
necessary challenge the validity or applicability of, any applicable Takeover
Laws.

         8.13 Articles of Incorporation Provisions. Each CHC Company shall take
all necessary action to ensure that the entering into of this Agreement and the
consummation of the Merger and the other transactions contemplated hereby do not
and will not result in the grant of any rights to any Person under the Articles
of Incorporation, Bylaws, or other governing instruments of any CHC Company or
restrict or 



                                      A-27
   148

impair the ability of FNB or any of its Subsidiaries to vote, or otherwise to
exercise the rights of a shareholder with respect to, shares of any CHC Company
that may be directly or indirectly acquired or controlled by it.

         8.14 Agreement of Affiliates. CHC has disclosed in Section 8.14 of the
CHC Disclosure Memorandum all Persons whom it reasonably believes are
"affiliates" of CHC for purposes of Rule 145 under the 1933 Act. CHC shall use
its reasonable best efforts to cause each such Person to deliver to FNB not
later than 10 days prior to the Effective Time, a written agreement,
substantially in the form of Exhibit 2 hereto, providing that such Person will
not sell, pledge, transfer, or otherwise dispose of the CHC Common Shares held
by such Person except as contemplated by such agreement or by this Agreement and
will not sell, pledge, transfer, or otherwise dispose of the shares of FNB
Common Stock to be received by such Person upon consummation of the Merger
except in compliance with applicable provisions of the 1933 Act and the rules
and regulations thereunder and until such time as financial results covering at
least 30 days of combined operations of FNB and CHC have been published within
the meaning of Section 201.01 of the SEC's Codification of Financial Reporting
Policies. Shares of FNB Common Stock issued to such affiliates of CHC in
exchange for CHC Common Shares shall not be transferable until such time as
financial results covering at least 30 days of combined operations of FNB and
CHC have been published within the meaning of Section 201.01 of the SEC's
Codification of Financial Reporting Policies, regardless of whether each such
affiliate has provided the written agreement referred to in this Section 8.14
(and FNB shall be entitled to place restrictive legends upon certificates for
shares of FNB Common Stock issued to affiliates of CHC pursuant to this
Agreement to enforce the provisions of this Section 8.14). FNB shall not be
required to maintain the effectiveness of the Registration Statement under the
1933 Act for the purposes of resale of FNB Common Stock by such affiliates.

         8.15 Employee Benefits and Contracts. All employees of CHC at the
Effective Time shall become employees of First National Bank of Florida.
Following the Effective Time, Southwest shall provide generally to officers and
employees of CHC employee benefits under employee benefit plans (other than
stock option or other plans involving the potential issuance of FNB Common
Stock), on terms and conditions which when taken as a whole are no less
favorable than those currently provided by CHC or those currently provided by
Southwest and its subsidiaries to their similarly situated officers and
employees, whichever is more favorable to officers and employees of CHC. For
purposes of participation and vesting (but not benefit accrual under any
employee benefit plans of Southwest and its subsidiaries other than the CHC
Benefit Plans) under such employee benefit plans, the service of the employees
of CHC prior to the Effective Time shall be treated as service with Southwest
and its subsidiaries participating in such employee benefit plans. FNB shall,
and shall cause its Subsidiaries to, honor in accordance with their terms all
employment, severance, consulting, and other compensation Contracts disclosed in
Section 8.15 of the CHC Disclosure Memorandum between CHC and any current or
former director, officer, or employee thereof, and all provisions for vested
benefits or other vested amounts earned or accrued through the Effective Time
under the CHC Benefit Plans.

         8.16 Retention of Directors. Immediately following the Effective Time
and for a period of one year, FNB shall cause the present directors of CHC to be
nominated and elected directors of First National Bank of Florida at a rate of
compensation for their services in an amount at least equal to that which they
are receiving from CHC as of the date of this Agreement.

         8.17 Employment Contracts of Certain Officers. Southwest, at the
Effective Time, shall enter into an Employment Agreement with David P. Stone
containing such terms and conditions as mutually agreeable. In consideration of
the entering into such employment agreement, Mr. Stone shall, at the Effective
Time, 



                                      A-28
   149

cancel and terminate the employment agreement dated as of December 16, 1986,
entered into with CHC including, without limitation, the provision respecting
change in control.

         8.18 Indemnification.

             (a) FNB shall, and shall cause the Surviving Corporation (and its
         successors and assigns) to, indemnify, defend, and hold harmless the
         present and former directors, officers, employees, and agents of CHC
         (each, an "Indemnified Party") after the Effective Time against all
         costs, fees, or expenses (including reasonable attorneys' fees),
         judgments, fines, penalties, losses, claims, damages, liabilities, and
         amounts paid in settlement in connection with any Litigation arising
         out of actions or omissions occurring at or prior to the Effective Time
         (including the transactions contemplated by this Agreement) to the full
         extent permitted under Florida Law and by CHC's Articles of
         Incorporation and Bylaws as in effect on the date hereof, including
         provisions relating to advances of expenses incurred in the defense of
         any Litigation. Without limiting the foregoing, in any case in which
         approval by FNB is required to effectuate any indemnification, FNB
         shall direct, or cause such FNB Company to direct, at the election of
         the Indemnified Party, that the determination of any such approval
         shall be made by independent counsel mutually agreed upon between FNB
         and the Indemnified Party. FNB shall, and shall cause the Surviving
         Corporation and all other relevant FNB Companies, to apply such rights
         of indemnification in good faith and to the fullest extent permitted by
         applicable Law.

             (b) Incident to any information furnished or disclosed by FNB or
         any FNB Company in connection with the Registration Statement and Proxy
         Statement, and subject to applicable Law, FNB shall indemnify, defend,
         and hold harmless the Indemnified Parties against all costs or expenses
         (including reasonable attorneys' fees), judgments, fines, penalties,
         losses, claims, damages, liabilities, and amounts paid in settlement in
         connection with any Litigation, whether civil or criminal,
         administrative, or investigative, arising out of or under the
         Securities Laws or any state blue sky or securities Laws based in whole
         or in part on (i) any untrue statement or alleged untrue statement of a
         material fact contained in such documents, including any amendment or
         supplement to such document, (ii) any omission or alleged omission to
         state in such documents a material fact required to be stated therein
         or necessary to make the statements therein not misleading, or (iii)
         any violation by FNB or an FNB Company of the Securities Laws or any
         state blue sky or securities Laws in connection with such documents;
         provided, however, that neither FNB or any FNB Company will be liable
         in any such case to the extent that any such claim, action, suit,
         proceeding or investigation is based upon any untrue statement or
         alleged untrue statement or omission or alleged omission made in such
         Registration Statement and Proxy Statement or any amendment thereto in
         reliance upon and in conformity with information furnished in writing
         to FNB or any FNB Company by CHC or any Indemnified Party specifically
         for use therein.

             (c) CHC and each Indemnified Party, jointly and severally, shall
         indemnify and hold harmless FNB, any FNB Company, each of its
         directors, officers, employees and agents, and each person who controls
         FNB or any FNB Company, against all costs or expenses (including
         reasonable attorneys' fees), judgments, fines, penalties, losses,
         claims, damages, liabilities, and amounts paid in settlement in
         connection with any Litigation, whether civil or criminal,
         administrative, or investigative, arising out of or under the
         Securities Laws or any state blue sky or securities Laws based in whole
         or in part on (i) any untrue statement or alleged untrue statement of a
         material fact contained in the Registration Statement or Proxy
         Statement (including any amendment or supplement to such document); or
         (ii) any omission or alleged omission to state in such documents
         material facts required to be stated therein or necessary to make the
         statements therein not misleading; provided,



                                      A-29
   150

         however, that CHC will not be liable in any such case to the extent
         that any such claim, action, suit, proceeding, or investigation is
         based upon any untrue statement or alleged untrue statement or omission
         or alleged omission made in such Registration Statement or Proxy
         Statement or any amendment thereto in reliance upon and conformity with
         information furnished in writing to CHC by FNB specifically for use
         therein.

             (d) If FNB or the Surviving Corporation or any of their successors
         or assigns shall consolidate with or merge into any other Person and
         shall not be the continuing or surviving Person of such consolidation
         or merger or shall transfer all or substantially all of its assets to
         any Person, then and in each case, proper provision shall be made so
         that the successors and assigns of FNB shall assume the obligations set
         forth in this Section 8.18.

             (e) The provisions of this Section 8.18 are intended to be for the
         benefit of and shall be enforceable by, each Indemnified Party, his or
         her heirs and representatives and shall survive the consummation of the
         Merger and be binding on all successors and assigns of FNB and the
         Surviving Corporation.

             (f) Prior to Closing, CHC shall purchase for, and on behalf of, its
         current and former officers and directors, extended coverage under the

obligations of each Party to perform this Agreement and consummate the Merger
and the other transactions contemplated hereby are subject to the satisfaction
of the following conditions, unless waived by both Parties pursuant to Section
11.7 of this Agreement:

             (a) Shareholder Approval. The shareholders of CHC shall have
         approved this Agreement, and the consummation of the transactions
         contemplated hereby, including the Merger, as and to the extent
         required by Law and the rules and regulations of Nasdaq.

             (b) Regulatory Approvals. All Consents of, filings and
         registrations with, and notifications to, all Regulatory Authorities
         required for consummation of the Merger shall have been obtained or
         made and shall be in full force and effect and all waiting periods
         required by Law shall have expired. No Consent obtained from any
         Regulatory Authority which is necessary to consummate the transactions
         contemplated hereby shall be conditioned or restricted in a manner
         (including requirements relating to the raising of additional capital
         or the disposition of Assets) which in the reasonable judgment of the
         Board of Directors of either Party would so materially adversely impact
         the economic or business benefits of the transactions contemplated by
         this Agreement that, had such condition or requirement been known, such
         Party would not, in its reasonable judgment, have entered into this
         Agreement.

             (c) Consents and Approvals. Other than filing the Florida Articles
         of Merger, each Party shall have obtained any and all Consents required
         for consummation of the Merger (other than those referred to in Section
         9.1(b) of this Agreement or listed in Section 9.1(c) of the CHC

         Memorandum) or for the preventing of any default under any Contract or
         Permit of such Party which, if not obtained or made, is reasonably
         likely to have, individually or in the aggregate, a Material Adverse
         Effect on such Party.

             (d) Legal Proceedings. No court or governmental or regulatory
         authority of competent jurisdiction shall have enacted, issued,
         promulgated, enforced, or entered any Law or Order (whether temporary,
         preliminary, or permanent) or taken any other action which prohibits,
         restricts, or makes illegal consummation of the transactions
         contemplated by this Agreement.

             (e) Registration Statement. The Registration Statement shall have
         been declared effective under the 1933 Act, and no stop orders
         suspending the effectiveness of the Registration Statement shall have
         been issued, and no action, suit, proceeding, or investigation by the
         SEC to suspend the effectiveness thereof shall have been initiated and
         be continuing, and all necessary approvals under state securities Laws
         or the 1933 Act or 1934 Act relating to the issuance or trading of the
         shares of FNB Common Stock issuable pursuant to the Merger shall have
         been received.

             (f) Pooling of Interests. Ernst & Young LLP, FNB's independent
         public accountants, shall have issued a letter dated as of the
         Effective Time, to CHC and FNB, respectively, to the effect that the
         Merger shall be accounted for as a pooling-of-interests under GAAP.

             (g) Tax Matters. Each Party shall have received a written opinion
         or opinions from Smith, Gambrell & Russell, LLP, and in a form
         reasonably satisfactory to such Parties (the "Tax Opinion"), to the
         effect that (i) the Merger will constitute a reorganization within the
         meaning of Section 368(a) of the Internal Revenue Code and (ii) the
         exchange in the Merger of CHC Common Shares for FNB Common Stock will
         not give rise to gain or loss to the shareholders of CHC with respect
         to such exchange (except to the extent of any cash received). In
         rendering such Tax Opinion, such counsel shall be entitled to rely upon
         representations of officers of CHC and FNB reasonably satisfactory in
         form and substance to such counsel.

         9.2 Conditions to Obligations of FNB. The obligations of FNB to

         been discovered by FNB, and reported in writing to CHC during such
         fourteen (14) calendar day period, any circumstance or condition in
         connection with a review of CHC Financial Statements, the general
         ledger and subsidiary ledgers maintained by CHC, CHC Contracts, minute
         books maintained by CHC of meetings of the Board of Directors,
         committees of the Board and meetings of shareholders, stock transfer
         records, credit or loan files, records regarding the calculation of
         CHC's allocation for loan and lease loss, records relating to
         transactions in CHC's securities portfolio, and Reports of Examination
         prepared by both the Federal Reserve Bank of Atlanta and the Federal
         Deposit Insurance Corporation which would require under GAAP a negative
         adjustment to shareholders' equity as set forth in the CHC Financial
         Statements of an amount equal to or greater than $100,000; (ii) Upon
         receipt of such written notice as set forth in this Section 9.2(a)(i)

         that the circumstance or condition giving rise to FNB's written
         notification pursuant to Section 9.2(a)(i) has been cured. In the event
         that FNB receives no notification from CHC during the thirty (30) days
         following a written notification to

         CHC pursuant to Section 9.2(a)(i) then CHC's right to cure under this
         provision shall have expired; and (iii) No item set forth in the CHC
         Disclosure Memorandum shall serve as a basis for notification by FNB to
         CHC pursuant to Section 9.2(a)(i) hereof.

         such inaccuracies has, or is reasonably likely to have, a Material
         Adverse Effect on CHC and its Subsidiaries taken as a whole; provided
         that, for purposes of this sentence only, those representations and
         warranties which are qualified by references to "material" or "Material
         Adverse Effect" shall be deemed not to include such qualifications.

             (c) Performance of Agreements and Covenants. Each and all of the

         pursuant to this Agreement and the other agreements contemplated hereby

         for pooling-of-interests accounting treatment.

             (f) Opinion of Counsel. FNB shall have received a written opinion
         of Carlton, Fields, Ward, Emmanuel, Smith & Cutler, P.A., counsel to
         CHC, dated as of the Effective Time, with respect to such matters and

         such inaccuracies has, or is reasonably likely to have, a Material

         only, those representations and warranties which are qualified by

         not to include such qualifications.

         minute books maintained by FNB of meetings of the Board of Directors,
         Committees of the Board and meetings of shareholders, and Reports of

                                   TERMINATION

         10.1 Termination. Notwithstanding any other provision of this
Agreement, and notwithstanding the approval of this Agreement by the
shareholders of CHC, this Agreement may be terminated and the Merger abandoned
at any time prior to the Effective Time:

              (a) By mutual written consent of the Board of Directors of FNB and
         the Board of Directors of CHC; or

              (b) By the Board of Directors of either FNB or CHC (provided that
         the terminating Party is not then in breach of any representation or
         warranty contained in this Agreement under the applicable standard set
         forth in Section 9.2(b) of this Agreement in the case of CHC and
         Section 9.3(a) in the case of FNB or in material breach of any covenant
         or other agreement contained in this Agreement) in the event of an
         inaccuracy of any representation or warranty of the other Party
         contained in this Agreement which cannot be or has not been cured
         within 30 days after the giving of written notice to the breaching
         Party of such inaccuracy and which inaccuracy would provide the
         terminating Party the ability to refuse to consummate the Merger under
         the applicable standard set forth in Section 9.2(b) of this Agreement
         in the case of CHC and Section 9.3(a) of this Agreement in the case of
         FNB; or

              (c) By the Board of Directors of either FNB or CHC in the event of
         a material breach by the other Party of any covenant, agreement, or
         obligation contained in this Agreement which breach cannot be or has
         not been cured within 30 days after the giving of written notice to the
         breaching Party of such breach; or

              (d) By the Board of Directors of either FNB or CHC in the event
         (i) any Consent of any Regulatory Authority required for consummation
         of the Merger and the other transactions contemplated hereby shall have
         been denied by final nonappealable action of such authority or if any
         action taken by such authority is not appealed within the time limit
         for appeal, or (ii) the shareholders of CHC fail to vote their approval
         of this Agreement and the transactions contemplated hereby as required
         by the FBCA at the Shareholders' Meeting where the transactions were
         presented to such shareholders for approval and voted upon; or

              (e) By the Board of Directors of either FNB or CHC in the event
         that the Merger shall not have been consummated by December 31, 1998,
         if the failure to consummate the transactions contemplated hereby on or
         before such date is not caused by any breach of this Agreement by the
         Party electing to terminate pursuant to this Section 10.1(e); or



                                      A-34
   155

              (f) By FNB in the event that dissenters' rights claimed pursuant
         to the applicable provisions of the FBCA, aggregate more than 10% of
         the issued and outstanding CHC Common Shares; or

              (g) By CHC, if its Board of Directors determines by a vote of a
         majority of the members of its entire Board of Directors, at any time
         during the period commencing on the Determination Date and ending at
         the closing of business on the day before the Closing, the Designated
         Price of FNB Common Stock shall be less then $34.125; or

              (h) By the Board of Directors of either FNB or CHC (provided that
         the terminating Party is not then in breach of any representation or
         warranty contained in this Agreement under the applicable standard set
         forth in Section 9.2(b) of this Agreement in the case of CHC and
         Section 9.3(a) in the case of FNB or in material breach of any covenant
         or other agreement contained in this Agreement) in the event that any
         of the conditions precedent to the obligations of such Party to
         consummate the Merger cannot be satisfied or fulfilled by the date
         specified in Section 10.1(e) of this Agreement; or

              (i) By CHC, if at any time prior to the Effective Time, the
         fairness opinion of Allen C. Ewing & Co. is withdrawn; or

              (j) By CHC if prior to the Effective Time, a corporation,
         partnership, person, or other entity or group shall have made a bona
         fide Acquisition Proposal that the CHC Board determines in its good
         faith judgment and in the exercise of its fiduciary duties, with
         respect to legal matters on the written opinion of legal counsel and as
         to financial matters on the written opinion of an investment banking
         firm of national reputation, is more favorable to the CHC stockholders
         and that the failure to terminate this Agreement and accept such
         alternative Acquisition Proposal would be inconsistent with the proper
         exercise of such fiduciary duties.

         10.2 Effect of Termination.

              (a) In the event of the termination and abandonment of this
         Agreement pursuant to Section 10.1 of this Agreement, this Agreement
         shall become void and have no effect, except that (i) the provisions of
         this Section 10.2 and Sections 8.5 and 11.1 of this Agreement shall
         survive any such termination and abandonment, and (ii) a termination
         pursuant to Sections 10.1(b) or 10.1(c), of this Agreement shall not
         relieve the breaching Party from liability for an uncured willful
         breach of a representation, warranty, covenant, or agreement giving
         rise to such termination; provided, further, that in the event of any
         termination of this Agreement following the occurrence of an Initial
         Triggering Event (as defined in the Stock Option Agreement) other than
         termination due to: (A) the failure of FNB to satisfy a condition to
         Closing or a termination covered by Section 10.2(b) of this Agreement,
         (B) determination of FNB pursuant to Section 9.2(a) not to perform this
         Agreement, (C) withdrawal of the fairness opinion of Allen C. Ewing &
         Co. (so long as such withdrawal is not due to materially inaccurate or
         fraudulent information provided by CHC to Allen C. Ewing & Co.), or (D)
         the failure to satisfy the conditions set forth in Section 9.1
         paragraphs (a), (b), (d), (e), (f) and (g), FNB shall be entitled to a
         cash payment from CHC in an amount equal to $250,000 upon the
         occurrence of any Subsequent Triggering Event (as defined in the Stock
         Option Agreement) within twelve (12) months following the date of such
         termination (or such longer period as shall exist under the Stock
         Option Agreement until the occurrence of an Exercise Termination Date
         (as defined in the Stock Option Agreement).

   156

              (b) In the event this Agreement is terminated as a result of FNB's
         failure to satisfy any of its representations, warranties or covenants
         set forth herein, FNB shall reimburse CHC for its reasonable
         out-of-pocket expenses relating to the Merger in an amount not to
         exceed $150,000, which amount shall not be deemed an exclusive remedy
         or liquidated damages.

         10.3 Non-Survival of Representations and Covenants. The respective
representations and warranties of the Parties shall not survive the Effective
Time. All agreements of the Parties to this Agreement which by their terms are
to be performed following the Effective Time shall survive the Effective Time

         of such Party at a later time to enforce the same or any other
         provision of this Agreement. No waiver of any condition or of the
         breach of any term contained in this Agreement in one or more instances

                                 FIRST AMENDMENT
                                       TO
                          AGREEMENT AND PLAN OF MERGER


         THIS FIRST AMENDMENT TO AGREEMENT AND PLAN OF MERGER (this "First
Amendment") is made and entered into as of June 30, 1998, by and among F.N.B.
CORPORATION ("FNB"), a Pennsylvania corporation, SOUTHWEST BANKS, INC.
("Southwest"), a Florida corporation and wholly-owned subsidiary of FNB and
CITIZENS HOLDING CORPORATION ("Citizens"), a Florida corporation.


                                    PREAMBLE

         The parties hereto entered into an Agreement and Plan of Merger (the
"Merger Agreement") dated as of April 6, 1998 whereby FNB, Southwest and
Citizens agreed to the merger of Citizens with and into Southwest. The parties
now desire to amend the Merger Agreement on the terms and conditions set forth
herein.

         NOW, THEREFORE, in consideration of the above and the mutual covenants
and agreements set forth herein, the parties agree as follows:

         1.       Conversion of Shares. (a) Section 3.1 of the Merger Agreement
is hereby amended by deleting paragraph (c) thereof in its entirety and
substituting therefor the following:

                           "(c) Except for CHC Common Shares issued and
                  outstanding immediately prior to the Effective Time as to
                  which dissenters' rights have been perfected and not
                  withdrawn, and subject to Section 3.4 relating to fractional
                  shares, each CHC Common Share (excluding shares to be
                  cancelled pursuant to Section 3.3 of this Agreement) issued
                  and outstanding at the Effective Time shall cease to be
                  outstanding and shall be converted into and exchanged for the
                  number of shares of FNB Common Stock (the "Exchange Ratio")
                  determined in accordance with Section 3.1(d) of this
                  Agreement."

                  (b) Section 3.1 of the Merger Agreement is further amended by
         deleting paragraph (d) thereof in its entirety and substituting
         therefor the following:

                           "(d) If the Designated Price of FNB Common Stock
                  shall be greater than $32.50 but less than $36.75, then the
                  Exchange Ratio shall be determined in accordance with the
                  table set forth on Exhibit "A" (the "Exchange Ratio Table"),
                  by reference to the Designated Price of FNB Common Stock,
                  rounded to the nearest such number included in the Exchange
                  Ratio Table. If the Designated Price of FNB Common Stock shall
                  be equal to or greater than $36.75, then the Exchange Ratio
                  shall equal the quotient, rounded to the third decimal place,
                  obtained by dividing 62.07 by the Designated Price. If the
                  Designated Price of FNB Common Stock shall be equal to or less
                  than $32.50, then the Exchange Ratio shall 


                                      A-48


   169


                  equal the quotient, rounded to the third decimal place,
                  obtained by dividing 56.16 by the Designated Price. If the
                  Designated Price of FNB Common Stock shall be less than
                  $30.00, then FNB may, at any time during the period commencing
                  on the Determination Date and ending at the close of business
                  five (5) business days thereafter, terminate the Agreement
                  pursuant to Section 10.1(g) hereof."

         2.       Registration Statement; Proxy Statement; Shareholder Approval.
Section 8.1 of the Merger Agreement is hereby amended by deleting the reference
to the date "May 31, 1998" in the parenthetical clause in the first sentence and
substituting in lieu thereof the date "July 15, 1998."

         3.       Certain Purchases. Section 8.10 of the Merger Agreement is 
hereby amended by deleting the word "content" contained in the tenth line of
such section and by substituting in lieu thereof the word "contest."

         4.       Termination. Section 10.1 of the Merger Agreement is hereby 
amended by deleting paragraph (g) thereof in its entirety and substituting
therefor the following:

                  "(g) By FNB, if at any time during the period commencing on
                  the Determination Date and ending on the day of Closing, the
                  Designated Price of FNB Common Stock shall be less than
                  $30.00; provided that FNB shall notify Citizens not later than
                  the close of business on the day before Closing of its
                  intention to terminate the Agreement pursuant to this Section
                  10.1 (g); or"

         5.       Defined Terms. All terms which are capitalized herein, but 
which are not defined herein, shall have the meanings ascribed to them in the
Merger Agreement.

         6.       Inconsistent Provisions. All provisions of the Merger 
Agreement which have not been amended by this First Amendment shall remain in
full force and effect. Notwithstanding the foregoing to the contrary, to the
extent that there is any inconsistency between the provisions of the Merger
Agreement and the provisions of this First Amendment, the provisions of this
First Amendment shall control and be binding.

to be executed on its behalf as of the date first written above. This First
Amendment may be executed in two or more counterparts which, when taken together
shall constitute a single original hereof.

                             STOCK OPTION AGREEMENT


         STOCK OPTION AGREEMENT, dated April 6, 1998, between F.N.B.
Corporation, a Pennsylvania corporation ("FNB"), and Citizens Holding
Corporation, a Florida corporation corporation ("CHC").

                              W I T N E S S E T H :

         WHEREAS, FNB and CHC have entered into an Agreement and Plan of Merger
of even date herewith (the "Merger Agreement"), which agreement has been
executed by the parties hereto prior to this Agreement; and

         WHEREAS, as a condition and inducement to FNB's pursuit of the
transactions contemplated by the Merger Agreement and in consideration therefor,
CHC has agreed to grant FNB the Option (as hereinafter defined):

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements set forth herein and in the Merger Agreement, the
parties hereto agree as follows:

         1. (a) CHC hereby grants to FNB an irrevocable option (the "Option") to
purchase, subject to the terms hereof, up to 144,292 authorized but unissued
fully paid and nonassessable Common Shares, $0.10 par value, of CHC ("Common
Shares"), at a price per share equal to $35.00 (as adjusted as set forth herein,
the "Option Price") payable in cash; provided, that in no event shall the number
of shares for which this Option is exercisable, when combined with the CHC
Common Shares beneficially owned at such time by FNB, exceed 19.9% of the issued
and outstanding Common Shares. The number of Common Shares that may be received
upon the exercise of the Option and the Option Price are subject to adjustment
as herein set forth.

            (b) In the event that any additional Common Shares are issued or
otherwise become outstanding after the date of this Agreement (other than
pursuant to this Agreement), the number of Common Shares subject to the Option
shall be increased so that, after such issuance, it equals 19.9% of the number
of Common Shares then issued and outstanding, including Common Shares
beneficially owned by FNB, but without giving effect to any shares subject or
issued pursuant to the Option. Nothing contained in this Section 1(b) or
elsewhere in this Agreement shall be deemed to authorize CHC or FNB to breach
any provision of the Merger Agreement.

         2. (a) Subject to compliance with applicable laws and regulations, the
Holder (as hereinafter defined) may exercise the Option, notwithstanding the
provisions of Section 8.5 of the Merger Agreement in whole or part, if, but only
if, both an Initial Triggering Event (as hereinafter defined) and a Subsequent
Triggering Event (as hereinafter defined) shall have occurred prior to the
occurrence of an Exercise Termination Event (as hereinafter defined). Each of
the following shall be an Exercise Termination Event: (i) the Effective Time (as
defined in the Merger Agreement) of the Merger; (ii) termination of the Merger
Agreement in accordance with the provisions thereof if such termination occurs
prior to the occurrence of an Initial Triggering Event; (iii) the passage of 12
months (or such longer period as provided in Section 10 of this Agreement) after
termination of the Merger Agreement if such termination follows the occurrence
of an Initial Triggering Event (other than a termination due to: (A) failure of
FNB to satisfy a condition to closing the Merger Agreement or a termination
covered by Section 10.2 of the Merger Agreement, (B) determination of FNB
pursuant to Section 9.2(a) of the Merger Agreement not to perform the Merger
Agreement, (C) the failure to satisfy the conditions to closing set forth in
Section 9.1 subparagraphs (a), (b), (d), (e), (f), and (g) of the Merger
Agreement, or (D) withdrawal of the fairness opinion of Allen C. Ewing & Co. (so
long as such withdrawal is not due to materially inaccurate or fraudulent
information provided by CHC to Allen C. Ewing & Co.), in which case an Event of
Termination occurs at the time of termination of the Merger Agreement,
notwithstanding the occurrence of an Initial Triggering Event); or (iv) such
other date as to which the Holder and CHC agree. The term "Holder" shall mean
the holder or holders of the Option. 


                                      B-1

   173


The rights set forth in Sections 7 and 9 of this Agreement shall terminate when
the right to exercise the Option terminates (other than as a result of a
complete exercise of the Option) as set forth herein.

            (b) The term "Initial Triggering Event" shall mean any of the
following events or transactions occurring after the date hereof:

                (i)   CHC, without having received FNB's prior written consent,
shall have entered into an agreement to engage in an Acquisition Transaction (as
hereinafter defined) with any person (the term "person" for purposes of this
Agreement having the meaning assigned thereto in Sections 3(a)(9) and 13(d)(3)
of the Securities Exchange Act of 1934 (the "1934 Act"), and the rules and
regulations thereunder) other than FNB or any of its Subsidiaries (each a "FNB
Subsidiary"), or the Board of Directors of CHC shall have recommended that the
shareholders of CHC approve or accept any Acquisition Transaction other than as
contemplated by the Merger Agreement or this Agreement. For purposes of this
Agreement, (A) "Acquisition Transaction" shall mean (x) a merger or
consolidation, or any similar transaction involving CHC, (y) a purchase, lease,
or other acquisition of all or substantially all of the assets or deposits of
CHC, or (z) a purchase or other acquisition (including by way of merger,
consolidation, share exchange or otherwise) of securities representing 15% or
more of the voting power of CHC, other than securities acquired by the CHC
officers and directors, and (B) "Subsidiary" shall have the meaning set forth in
Rule 12b-2 under the 1934 Act;

                (ii)  Any person (excluding the officers and directors of CHC)
other than FNB or any FNB Subsidiary acting in a fiduciary capacity shall have
acquired beneficial ownership or the right to acquire beneficial ownership of
15% or more of the outstanding Common Shares (the term "beneficial ownership"
for purposes of this Agreement having the meaning assigned thereto in Section
13(d) of the 1934 Act, and the rules and regulations thereunder);

                (iii) The shareholders of CHC shall not have approved the
transactions contemplated by the Merger Agreement at the meeting held for that
purpose or any adjustment thereof, or such meeting shall not have been held or
shall have been canceled prior to termination of the Merger Agreement, in either
case, after CHC's Board of Directors shall have withdrawn or modified (or
publicly announced its intention to withdraw or modify or interest in
withdrawing or modifying) its recommendation that the shareholders of CHC
approve the transactions contemplated by the Merger Agreement, or CHC, without
having received FNB's prior written consent, shall have authorized, recommended,
or proposed (or publicly announced its intention to authorize, recommend or
propose or interest in authorizing, recommending or proposing) an agreement to
engage in an Acquisition Transaction with any person other than FNB or a FNB
Subsidiary;

                (iv)  CHC shall have willfully and materially breached any
material covenant or obligation contained in the Merger Agreement in
anticipation of engaging in an Acquisition Transaction, and such breach would
entitle FNB to terminate the Merger Agreement; or

                (v)   Any person other than FNB or any FNB Subsidiary, other
than in connection with a transaction to which FNB has given its prior written
consent, shall have filed an application or notice with the Federal Reserve
Board or other federal or state bank regulatory authority, which application or
notice has been accepted for processing, for approval to engage in an
Acquisition Transaction.

            (c) The term "Subsequent Triggering Event" shall mean any of the
following events or transactions occurring after the date hereof:

                (i)   The acquisition by any person of beneficial ownership of 
25% or more of the then outstanding Common Shares; or



                                      B-2

   174



                (ii)  The occurrence of the Initial Triggering Event described
in clause (i) of subsection (b) of this Section 2, except that the percentage
referred to in clause (z) shall be 25%.

            (d) CHC shall notify FNB promptly in writing of the occurrence of
any Initial Triggering Event or Subsequent Triggering Event (together, a
"Triggering Event"), it being understood that the giving of such notice by CHC
shall not be a condition to the right of the Holder to exercise the Option.

            (e) No shares shall be issued pursuant to the exercise of this
Option if (i) at the time of the Initial Triggering Event and at the time of
exercise, FNB is in material breach under the Merger Agreement, or (ii) a
preliminary or permanent injunction has been issued by a court of proper
jurisdiction.

            (f) In the event the Holder is entitled to and wishes to exercise
the Option, it shall send to CHC a written notice prior to an Exercise
Termination Event (the date of which being herein referred to as the "Notice
Date") specifying (i) the total number of shares it will purchase pursuant to
such exercise and (ii) a place and date not earlier than three (3) business days
nor later than ten (10) business days from the Notice Date for the closing of
such purchase (the "Closing Date"); provided that if prior notification to or
approval of the Federal Reserve Board or any other regulatory agency is required
in connection with such purchase, the Holder shall promptly file the required
notice or application for approval, shall promptly notify CHC of such filing,
and shall expeditiously process the same and the period of time that otherwise
would run pursuant to this sentence shall run instead from the date on which any
required notification periods have expired or been terminated or such approvals
have been obtained and any requisite waiting period or periods shall have
passed. Any exercise of the Option shall be deemed to occur on the Notice Date
relating thereto.

            (g) At the closing referred to in subsection (f) of this Section 2,
the Holder shall pay to CHC the aggregate purchase price for the Common Shares
purchased pursuant to the exercise of the Option in immediately available funds
by wire transfer to a bank account designated by CHC, provided that failure or
refusal of CHC to designate such a bank account shall not preclude the Holder
from exercising the Option.

            (h) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (g) of this Section 2, CHC shall
deliver to the Holder a certificate or certificates representing the number of
Common Shares purchased by the Holder and, if the Option should be exercised in
part only, a new Option evidencing the rights of the Holder thereof to purchase
the balance of the shares purchasable thereunder. In addition, the Holder shall
provide to CHC a letter agreeing that Holder will not offer to sell or dispose
of such shares in violation of applicable law or this Agreement

            (i) Certificates for Common Shares delivered at a closing hereunder
may be endorsed with a restrictive legend that shall read substantially as
follows:

                "The transfer of the shares represented by this certificate is
                subject to certain provisions of an agreement between the
                registered holder hereof and CHC and to resale restrictions
                arising under the Securities Act of 1933, as amended. A copy of
                such agreement is on file at the principal office of CHC and
                will be provided to the holder hereof without charge upon
                receipt by CHC of a written request therefor."

                It is understood and agreed that: (i) the reference to the 
resale restrictions of the Securities Act of 1933 (the "1933 Act") in the above
legend shall be removed by delivery of a substitute certificate(s) without such
reference if the Holder shall have delivered to CHC a copy of a letter from the
Staff of the SEC, or an opinion of counsel, in form and substance satisfactory
to CHC, to the effect that such legend is not required for purposes of the 1933
Act; (ii) the reference to the provisions of this Agreement in the above legend
shall be removed by delivery of a substitute certificate(s) without such
reference if the shares have 


                                      B-3


   175


been sold or transferred in compliance with the provisions of this Agreement and
under circumstances that do not require the retention of such reference; and
(iii) the above legend shall be removed in its entirety if the conditions in the
preceding clauses (i) and (ii) are both satisfied. In addition, such
certificates shall bear any other legend as may be required by law.

            (j) Upon the giving by the Holder to CHC of the written notice of
exercise of the Option provided for under subsection (f) of this Section 2 and
the tender of the applicable purchase price in immediately available funds, the
Holder shall be deemed to be the holder of record of the Common Shares issuable
upon such exercise, notwithstanding that the stock transfer books of CHC shall
then be closed or that certificates representing such Common Shares shall not
then be actually delivered to the Holder. CHC shall pay all expenses, and any
and all United States federal, state and local taxes and other charges that may
be payable in connection with the preparation, issue and delivery of stock
certificates under this Section 2 in the name of the Holder or its assignee,
transferee or designee.

         3. CHC agrees: (a) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Common Shares so that the Option may be exercised without additional
authorization of Common Shares after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Shares; (b)
that it will not, by charter amendment or through reorganization, consolidation,
merger, dissolution, or sale of assets, or by any other voluntary act, avoid or
seek to avoid the observance or performance of any of the covenants,
stipulations, or conditions to be observed or performed hereunder by CHC; (c)
promptly to take all action as may from time to time be required (including (i)
complying with all premerger notification, reporting and waiting period
requirements specified in 15 U.S.C. Section 18a and regulations promulgated
thereunder and (ii) in the event, under the Bank Holding Company Act of 1956, as
amended, or any state or other federal banking law, prior approval of or notice
to the Federal Reserve Board or to any state or other federal regulatory
authority is necessary before the Option may be exercised, cooperating fully
with the Holder in preparing such applications or notices and providing such
information to the Federal Reserve Board or such state or other federal
regulatory authority as they may require) in order to permit the Holder to
exercise the Option and CHC duly and effectively to issue Common Shares pursuant
hereto; and (d) promptly to take all action provided herein to protect the
rights of the Holder against dilution as set forth in Section 5 hereof.

         4. This Agreement (and the Option granted hereby) are exchangeable,
without expense, at the option of the Holder, upon presentation and surrender of
this Agreement at the principal office of CHC, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of Common Shares purchasable hereunder. The terms
"Agreement" and "Option" as used herein include any Agreements and related
Options for which this Agreement (and the Option granted hereby) may be
exchanged. Upon receipt by CHC of evidence reasonably satisfactory to it of the
loss, theft, destruction or mutilation of this Agreement, and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and upon
surrender and cancellation of this Agreement, if mutilated, CHC will execute and
deliver a new Agreement of like tenor and date.

         5. The number of Common Shares purchasable upon the exercise of the
Option shall be subject to adjustment from time to time as provided in this
Section 5.

            (a) In the event of any change in Common Shares by reason of stock
dividends, splitups, mergers, recapitalizations, combinations, subdivisions,
conversions, exchanges of shares or the like, the type and number of Common
Shares purchasable upon exercise hereof shall be appropriately adjusted and
proper provision shall be made so that, in the event any additional Common
Shares are to be issued or otherwise become outstanding as a result of any such
change (other than pursuant to an exercise of the Option), the number of Common
Shares that remain subject to the Option shall be increased so that, after such
issuance 


                                      B-4


   176


and together with Common Shares previously issued pursuant to the exercise of
the Option (together with the number of Shares previously issued under this
Option and the number of Shares otherwise beneficially owned by FNB) (as
adjusted on account of any of the foregoing changes in the Common Shares), it
equals 19.9% of the number of Common Shares then issued and outstanding.

            (b) Whenever the number of Common Shares purchasable upon exercise
hereof is adjusted as provided in this Section 5, the Option Price shall be
adjusted by multiplying the Option Price by a fraction, the numerator of which
shall be equal to the number of Common Shares purchasable prior to the
adjustment and the denominator of which shall be equal to the number of Common
Shares purchasable after the adjustment.

         6. Upon the occurrence of a Subsequent Triggering Event that occurs
prior to an Exercise Termination Event, CHC shall, at the request of FNB
delivered prior to an Exercise Termination Event (or such later period as
provided in Section 10) (whether on its own behalf or on behalf of any
subsequent holder of this Option (or part thereof) or any of the Common Shares
issued pursuant hereto), promptly prepare, file and keep current a registration
statement under the 1933 Act covering any shares issued and issuable pursuant to
this Option and shall use its best efforts to cause such registration statement
to become effective and remain current in order to permit the sale or other
disposition of any Common Shares issued upon total or partial exercise of this
Option ("Option Shares") in accordance with any plan of disposition requested by
FNB. CHC will use its best efforts to cause such registration statement first to
become effective and then to remain effective for such period not in excess of
120 days from the day such registration statement first becomes effective or
such shorter time as may be reasonably necessary to effect such sales or other
dispositions. FNB shall have the right to demand two such registrations. The
first demand registration effected under this Section 6 shall be at CHC's
expense up to $40,000, such expense in excess of $40,000 to be paid by FNB,
except for underwriting commissions and the fees and expenses of FNB's counsel
attributable to the registration of the Common Shares. The second demand
registration shall be at FNB's expense. In addition, if at any time after the
occurrence of a Subsequent Triggering Event that occurs prior to an Exercise
Termination Event, CHC proposes to register any of its equity securities under
the 1933 Act, whether for sale for its own account or for the account of any
other person, on a form and in a manner which would permit registration of the
Common Shares issued pursuant hereto for sale to the public under the 1933 Act,
it will each such time give prompt written notice to FNB of its intention to do
so, describing such securities and specifying the form and manner and the other
relevant facts involved in such proposed registration, and upon the written
request of FNB delivered to the Company within 10 business days after the giving
of any such notice (which request shall specify the Common Shares intended to be
disposed of and the intended method or methods of disposition thereof), CHC will
use its best efforts to effect the registration under the 1933 Act of all Common
Shares which CHC has been so requested to register by FNB, to the extent
requisite to permit the disposition of the Common Shares in accordance with the
intended methods thereof as specified by FNB. CHC shall be obligated to effect
only one such piggy-back registration pursuant to this Section 6. FNB shall pay
such incremental expenses incurred by CHC in connection with registering the
Common Shares requested to be registered by FNB pursuant to its piggy-back
registration rights under this Section 6, which expenses are in addition to the
expenses that CHC would have otherwise incurred in registering equity securities
under the 1933 Act. The foregoing notwithstanding, if, at the time of any
request by FNB for registration of Option Shares as provided above, CHC has
initiated discussions with investment bankers concerning, or is in registration
with respect to, an underwritten public offering of Common Shares, and if in the
good faith judgment of the managing underwriter or managing underwriters, or, if
none, the sole underwriter or underwriters, of such offering the inclusion of
the Option Shares would interfere with the successful marketing of the Common
Shares offered by CHC, the number of Option Shares otherwise to be covered in
the registration statement contemplated hereby may be reduced; provided,
however, that after any such required reduction the number of Option Shares to
be included in such offering for the account of the Holder shall constitute at
least 25% of the total number of shares to be sold by the Holder and CHC in the
aggregate; and provided further, however, that if such reduction occurs, then
CHC 


                                      B-5


   177


shall file a registration statement for the balance as promptly as practical
thereafter as to which no reduction pursuant to this Section 6 shall be
permitted or occur and the Holder shall thereafter be entitled to one additional
registration. Each such Holder shall provide all information reasonably
requested by CHC for inclusion in any registration statement to be filed
hereunder. If requested by any such Holder in connection with such registration,
CHC shall become a party to any underwriting agreement relating to the sale of
such shares, but only to the extent of obligating itself in respect of
representations, warranties, indemnities and other agreements customarily
included in such underwriting agreements for CHC. In any such registration, CHC
and FNB shall agree to indemnify each other on customary terms with regard to
any information provided by such party. Upon receiving any request under this
Section 6 from any Holder, CHC agrees to send a copy thereof to any other person
known to CHC to be entitled to registration rights under this Section 6, in each
case by promptly mailing the same, postage prepaid, to the address of record of
the persons entitled to receive such copies. The filing of any registration
statement under this Section 6 may be delayed for a period of time, not to
exceed 180 days, as may reasonably be required to facilitate any public
distribution by CHC of its Common Shares (or of a holding company parent of
CHC).

         7. (a) Upon the occurrence of a Repurchase Event (as hereinafter
defined) that occurs prior to an Exercise Termination Event, (i) at the request
of the Holder, delivered prior to an Exercise Termination Event (or such later
period as provided in Section 10), CHC shall repurchase the Option from the
Holder at a price (the "Option Repurchase Price") equal to the amount by which
(A) the Market/Offer Price (as defined below) exceeds (B) the Option Price,
multiplied by the number of shares for which this Option may then be exercised
and (ii) at the request of the owner of Option Shares from time to time (the
"Owner"), delivered prior to the occurrence of an Exercise Termination Event (or
such later period as provided in Section 10), CHC shall repurchase such number
of the Option Shares from the Owner as the Owner shall designate at a price (the
"Option Share Repurchase Price") equal to the Market/Offer Price multiplied by
the number of Option Shares so designated. The term "Repurchase Event" shall
occur if (i) any person other than FNB or any of its Subsidiaries shall have
acquired beneficial ownership, or the right to acquire beneficial ownership, or
any "group" (as such term is defined under the 1934 Act) shall have been formed
which beneficially owns or has the right to acquire beneficial ownership of 50%
or more of the then outstanding Common Shares, or (ii) any of the transactions
described in Section 8(a)(i), 8(a)(ii), or 8(a)(iii) of this Agreement shall be
consummated. The term "Market/Offer Price" shall mean the highest of (i) the
price per share of Common Shares at which a tender or exchange offer therefor
has been made, (ii) the price per share of Common Shares to be paid by any third
party pursuant to an agreement with CHC, (iii) in the event of a sale of all or
substantially all of CHC's assets or deposits, the sum of the net price paid in
such sale for such assets or deposits, the sum of the net price paid in such
sale for such assets or deposits and the current market value of the remaining
net assets of CHC as determined by a nationally recognized investment banking
firm selected by the Holder or the Owner, as the case may be, divided by the
number of Common Shares of CHC outstanding at the time of such sale. In
determining the Market/Offer Price, the value of consideration other than cash
shall be determined by a nationally recognized investment banking firm selected
by the Holder or Owner, as the case may be.

            (b) The Holder and the Owner, as the case may be, may exercise its
right to require CHC to repurchase the Option and any Option Shares pursuant to
this Section 7 by surrendering for such purpose to CHC, at its principal office,
a copy of this Agreement or certificates for Option Shares, as applicable,
accompanied by a written notice or notices stating that the Holder or the Owner,
as the case may be, elects to require CHC to repurchase this Option and/or the
Option Shares in accordance with the provisions of this Section 7. As promptly
as practicable, and in any event within ten (10) business days after the
surrender of the Option and/or certificates representing Option Shares and the
receipt of such notice or notices relating thereto, CHC shall deliver or cause
to be delivered to the Holder the Option Repurchase Price and/or to the Owner
the Option Share Repurchase Price therefor or the portion thereof that CHC is
not then prohibited under applicable law and regulation from so delivering.


                                      B-6


   178


            (c) To the extent that CHC is prohibited under applicable law or
regulation, or as a consequence of administrative policy, from repurchasing the
Option and/or the Option Shares in full, CHC shall immediately so notify the
Holder and/or the Owner and thereafter deliver or cause to be delivered, from
time to time, to the Holder and/or the Owner, as appropriate, the portion of the
Option Repurchase Price and the Option Share Repurchase Price, respectively,
that it is no longer prohibited from delivering, within ten (10) business days
after the date on which CHC is no longer so prohibited; provided, however, that
if CHC at any time after delivery of a notice of repurchase pursuant to
paragraph (b) of this Section 7 is prohibited under applicable law or
regulation, or as a consequence of administrative policy, from delivery to the
Holder and/or the Owner, as appropriate, the Option Repurchase Price and the
Option Share Repurchase Price, respectively, in full (and CHC hereby undertakes
to use its best efforts to obtain all required regulatory and legal approvals
and to file any required notices as promptly as practicable in order to
accomplish such repurchase), the Holder or Owner may revoke its notice of
repurchase of the Option or the Option Shares whether in whole or to the extent
of the prohibition, whereupon, in the latter case, CHC shall promptly (i)
deliver to the Holder and/or the Owner, as appropriate, that portion of the
Option Purchase Price or the Option Share Repurchase Price that CHC is not
prohibited from delivering, and (ii) deliver, as appropriate, either (A) to the
Holder, a new Agreement evidencing the right of the Holder to purchase that
number of Common Shares obtained by multiplying the number of Common Shares for
which the surrendered Agreement was exercisable at the time of delivery of the
notice of repurchase by a fraction, the numerator of which is the Option
Repurchase Price less the portion thereof theretofore delivered to the Holder
and the denominator of which is the Option Repurchase Price, or (B) to the
Owner, a certificate for the Option Shares it is then so prohibited from
repurchasing.

         8. (a) In the event that, prior to an Exercise Termination Event, CHC
shall enter into an agreement (i) to consolidate with or merge into any person,
other than FNB or a FNB Subsidiary, and shall not be the continuing or surviving
corporation of such consolidation or merger, (ii) to permit any person, other
than FNB or a FNB Subsidiary, to merge into CHC and CHC shall be the continuing
or surviving corporation, but, in connection with such merger, the then
outstanding Common Shares shall be changed into or exchanged for stock or other
securities of any other person or cash or any other property or the then
outstanding Common Shares shall after such merger represent less than 50% of the
outstanding shares and share equivalents of the merged company, or (iii) to sell
or otherwise transfer all or substantially all of its assets or deposits to any
person, other than FNB or a FNB Subsidiary, then, and in each such case, the
agreement governing such transaction shall make proper provision so that the
Option shall, upon the consummation of any such transaction and upon the terms
and conditions set forth herein, be converted into, or exchanged for, an option
(the "Substitute Option"), at the election of the Holder, of either (A) the
Acquiring Corporation (as hereinafter defined) or (B) any person that controls
the Acquiring Corporation.

            (b) The following terms have the meanings indicated:

                (i)   "Acquiring Corporation" shall mean (i) the continuing or
surviving corporation of a consolidation or merger with CHC (if other than CHC),
(ii) CHC in a merger in which CHC is the continuing or surviving person, and
(iii) the transferee of all or substantially all of CHC's assets or deposits.

                (ii)  "Substitute Common Shares" shall mean the common shares
issued by the issuer of the Substitute Option upon exercise of the Substitute
Option.

                (iii) "Assigned Value" shall mean the Market/Offer Price, as
defined in Section 7.

                (iv)  "Average Price" shall mean the average closing price of 
the Substitute Common Shares for the one year immediately preceding the
consolidation, merger, or sale in question, but in no event higher than the
closing price of the Substitute Common Shares on the day preceding such
consolidation, merger, or sale; provided that if CHC is the issuer of the
Substitute Option, the Average Price shall be computed with


                                      B-7



   179


respect to common shares issued by the person merging into CHC or by any company
which controls or is controlled by such person, as the Holder may elect.

            (c) The Substitute Option shall have the same terms as the Option,
provided that if the terms of the Substitute Option cannot, for legal reasons,
be the same as the Option, such terms shall be as similar as possible and in no
event less advantageous to the Holder. The issuer of the Substitute Option shall
also enter into an agreement with the then Holder or Holders of the Substitute
Option in substantially the same form as this Agreement (after giving effect for
such purpose to the provisions of Section 9), which agreement shall be
applicable to the Substitute Option.

            (d) The Substitute Option shall be exercisable for such number of
Substitute Common Shares as is equal to the Assigned Value multiplied by the
number of Common Shares for which the Option is then exercisable, divided by the
Average Price. The exercise price of the Substitute Option per Substitute Common
Share shall then be equal to the Option Price multiplied by a fraction, the
numerator of which shall be the number of Common Shares for which the Option is
then exercisable and the denominator of which shall be the number of Substitute
Common Shares for which the Substitute Option is exercisable.

            (e) In no event, pursuant to any of the foregoing paragraphs, shall
the Substitute Option be exercisable for a number of shares which together with
shares of the Acquiring Corporation then beneficially owned by FNB, constitutes
more than 19.9% of the shares of Substitute Common Shares outstanding prior to
exercise of the Substitute Option.

         9. (a) At the request of the holder of the Substitute Option (the
"Substitute Option Holder"), the issuer of the Substitute Option (the
"Substitute Option CHC") shall repurchase the Substitute Option from the
Substitute Option Holder at a price (the "Substitute Option Repurchase Price")
equal to the amount by which (i) the Highest Closing Price (as hereinafter
defined) exceeds (ii) the exercise price of the Substitute Option, multiplied by
the number of Substitute Common Shares for which the Substitute Option may then
be exercised, and at the request of the owner (the "Substitute Share Owner") of
shares of Substitute Common Shares (the "Substitute Shares"), the Substitute
Option CHC shall repurchase the Substitute Shares at a price (the "Substitute
Share Repurchase Price") equal to the Highest Closing Price multiplied by the
number of Substitute Shares so designated. The term "Highest Closing Price"
shall mean the highest closing price for shares of Substitute Common Shares
within the three-month period immediately preceding the date the Substitute
Option Holder gives notice of the required repurchase of the Substitute Option
or the Substitute Share Owner gives notice of the required repurchase of the
Substitute Shares, as applicable.

            (b) The Substitute Option Holder and the Substitute Share Owner, as
the case may be, may exercise its respective right to require the Substitute
Option CHC to repurchase the Substitute Option and the Substitute Shares
pursuant to this Section 9 by surrendering for such purpose to the Substitute
Option CHC, at its principal office, the agreement for such Substitute Option
(or, in the absence of such an agreement, a copy of this Agreement) and
certificates for Substitute Shares accompanied by a written notice or notices
stating that the Substitute Option Holder or the Substitute Share Owner, as the
case may be, elects to require the Substitute Option CHC to repurchase the
Substitute Option and/or the Substitute Shares in accordance with the provisions
of this Section 9. As promptly as practicable, and in any event within ten (10)
business days after the surrender of the Substitute Option and/or certificates
representing Substitute Shares and the receipt of such notice or notices
relating thereto, the Substitute Option CHC shall deliver or cause to be
delivered to the Substitute Option Holder the Substitute Option Repurchase Price
and/or to the Substitute Share Owner the Substitute Share Repurchase Price
therefor or the portion thereof which the Substitute Option CHC is not then
prohibited under applicable law and regulation from so delivering.

            (c) To the extent that the Substitute Option CHC is prohibited under
applicable law or regulation, or as a consequence of administrative policy, from
repurchasing the Substitute 


                                      B-8


   180


Option and/or the Substitute Shares in part or in full, the Substitute Option
CHC shall immediately so notify the Substitute Option Holder and/or the
Substitute Share Owner and thereafter deliver or cause to be delivered, from
time to time, to the Substitute Option Holder and/or the Substitute Share Owner,
as appropriate, the portion of the Substitute Share Repurchase Price,
respectively, which it is no longer prohibited from delivering, within ten (10)
business days after the date on which the Substitute Option CHC is no longer so
prohibited; provided, however, that if the Substitute Option CHC is at any time
after delivery of a notice of repurchase pursuant to subsection (b) of this
Section 9 prohibited under applicable law or regulation, or as a consequence of
administrative policy, from delivering to the Substitute Option Holder and/or
the Substitute Share Owner, as appropriate, the Substitute Option Repurchase
Price and the Substitute Share Repurchase Price, respectively, in full (and the
Substitute Option CHC shall use its best efforts to receive all required
regulatory and legal approvals as promptly as practicable in order to accomplish
such repurchase), the Substitute Option Holder or Substitute Share Owner may
revoke its notice of repurchase of the Substitute Option or the Substitute
Shares either in whole or to the extent of the prohibition, whereupon, in the
latter case, the Substitute Option CHC shall promptly (i) deliver to the
Substitute Option Holder or Substitute Share Owner, as appropriate, that portion
of the Substitute Option Repurchase Price or the Substitute Share Repurchase
Price that the Substitute Option CHC is not prohibited from delivering; and (ii)
deliver, as appropriate, either (A) to the Substitute Option Holder, a new
Substitute Option evidencing the right of the Substitute Option Holder to
purchase that number of the Substitute Common Shares obtained by multiplying the
number of Substitute Common Shares for which the surrendered Substitute Option
was exercisable at the time of delivery of the notice of repurchase by a
fraction, the numerator of which is the Substitute Option Repurchase Price less
the portion thereof theretofore delivered to the Substitute Option Holder and
the denominator of which is the Substitute Option Repurchase Price, or (B) to
the Substitute Share Owner, a certificate for the Substitute Option Shares it is
then so prohibited from repurchasing.

         10. The periods for exercise of certain rights under Sections 2, 6, 7,
9 and 13 shall be extended: (i) to the extent necessary to obtain all regulatory
approvals for the exercise of such rights (for so long as the Holder is using
commercially reasonable efforts to obtain such regulatory approvals), and for
the expiration of all statutory waiting periods; and (ii) to the extent
necessary to avoid liability under Section 16(b) of the 1934 Act by reason or
such exercise.

         11. CHC hereby represents and warrants to FNB as follows:

            (a) CHC has full corporate power and authority to execute and
deliver this Agreement and, subject to any approvals required by federal or
state banking authorities and any other relevant agency, to consummate the
transactions contemplated hereby. The execution and delivery this Agreement and
the consummation of the transactions contemplated hereby have been duly and
validly authorized by the Board of Directors of CHC and no other corporate
proceedings on the part of CHC are necessary to authorize this Agreement or to
consummate the transactions so contemplated. This Agreement has been duly and
validly executed and delivered by CHC.

            (b) CHC has taken all necessary corporate action to authorize and
reserve and to permit it to issue, and at all times from the date hereof through
the termination of this Agreement in accordance with its terms will have
reserved for issuance upon the exercise of the Option, that number of Common
Shares equal to the maximum number of Common Shares at any time and from time to
time issuable hereunder, and all such shares, upon issuance pursuant thereto,
will be duly authorized, validly issued, fully paid, nonassessable.

         12. FNB hereby represents and warrants to CHC as follows: FNB, its
assigns, or both will acquire the Option (including any Substitute Options) and
Option Shares for investment purposes only and not with any intent or a view to
resell or distribute such Option within the meaning of Section 2(11) of the 1933
Act, and will not sell, distribute, assign, hypothecate, or otherwise transfer
such Option, Substitute Options, or Option Shares except in accordance with the
1933 Act and all applicable federal and state securities laws.


                                      B-9


   181


         13. Neither of the parties hereto may assign any of its rights or
obligations under this Agreement or the Option created hereunder to any other
person, without the express written consent of the other party, except that in
the event a Subsequent Triggering Event shall have occurred prior to an Exercise
Termination Event, FNB, subject to the express provisions hereof, may assign in
whole or in part its rights and obligations hereunder following such Subsequent
Triggering Event; provided, however, that until the date thirty (30) days
following the date on which the Federal Reserve Board has approved applications
by FNB to acquire the Common Shares subject to the Option, FNB may not assign
its rights under the Option except in (i) a widely dispersed public
distribution, (ii) a private placement in which no one party acquires the right
to purchase in excess of 2% of the voting shares of issuer, (iii) an assignment
to a single party (i.e., a broker or investment banker) for the purpose of
conducting a widely disbursed public distribution on FNB's behalf, or (iv) any
other manner approved by the Federal Reserve Board.

         14. Each of FNB and CHC will use its best efforts to make all filings
with, and to obtain consents of, all third parties and governmental authorities
necessary to the consummation of the transactions contemplated by this
Agreement, including without limitation applying to the Federal Reserve Board
under the Bank Holding Company Act for approval to acquire the shares issuable
hereunder.

         15. The parties hereto acknowledge that damages would be an inadequate
remedy for a breach of this Agreement by either party hereto and that the
obligations of the parties hereto shall be enforceable by either party hereto
through injunctive or other equitable relief.

         16. If any term, provision, covenant, or restriction contained in this
Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void, or unenforceable, the remainder of
the terms, provisions, and covenants and restrictions contained in this
Agreement shall remain in full force and effect, and shall in no way be
affected, impaired, or invalidated. If for any reason such court or regulatory
agency determines that the Holder is not permitted to acquire, or CHC is not
permitted to repurchase pursuant to Section 7, the full number of Common Shares
provided in Section 1(a) hereof (as adjusted pursuant to Section 5 hereof), it
is the express intention of CHC to allow the Holder to acquire or to require CHC
to repurchase such lesser number of shares as may be permissible, without any
amendment or modification hereof.

         17. All notices, requests, claims, demands, and other communications
hereunder shall be deemed to have been duly given when delivered in person, by
fax, telecopy, or by registered or certified mail (postage prepaid, return
receipt requested) at the respective addresses of the parties set forth in the
Merger Agreement.

         18. This Agreement shall be governed by and construed in accordance
with the laws of the State of Florida, regardless of the laws that might
otherwise govern under applicable principles of conflicts of laws thereof.

         19. This Agreement may be executed in two or more counterparts, each of
which shall be deemed to be an original, but all of which shall constitute one
and the same agreement.

         20. Except as otherwise expressly provided herein, each of the parties
hereto shall bear and pay all costs and expenses incurred by it or on its behalf
in connection with the transactions contemplated hereunder, including fees and
expenses of its own financial consultants, investment bankers, accountants, and
counsel.

         21. Except as otherwise expressly provided herein or in the Merger
Agreement, this Agreement contains the entire agreement between the parties with
respect to the transactions contemplated hereunder and supersedes all prior
arrangements or understandings with respect thereof, written or oral. The terms
and conditions of this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assignees.
Nothing in this Agreement, expressed or implied, is intended to confer upon any
party, other than the parties hereto, and their 



                                      B-10


   182


respective successors except as assignees, any rights, remedies, obligations, or
liabilities under or by reason of this Agreement, except as expressly provided
herein.

         22. Capitalized terms used in this Agreement and not defined herein
shall have the meanings assigned thereto in the Merger Agreement.









                                      B-11



   183


         IN WITNESS WHEREOF, each of the parties had caused this Agreement to be
executed on its behalf by their officers thereunto duly authorized, all as the

May 15, 1998


Board of Directors
Citizens Holding Corporation
1150 Cleveland Street
Clearwater, Florida  33755

Gentlemen:

You have requested our opinion as to the fairness, from a financial point of
view, to the shareholders of Citizens Holding Corporation ("CHC") of Clearwater,
Florida, the bank holding company for Citizens Bank & Trust ("Bank") of the
consideration to be paid to the shareholders of CHC by F.N.B. Corporation
("F.N.B.") of Hermitage, Pennsylvania, as provided by the Agreement and Plan of
Merger ("Merger Agreement") entered into by the parties on April 6, 1998.
Pursuant to the Merger Agreement, F.N.B. will acquire all of the outstanding
shares of CHC by exchanging F.N.B. shares for the shares of CHC. Outstanding CHC
options will be assumed by F.N.B. CHC will be merged with and into F.N.B. and
CHC will cease to exist as a corporation. The Bank will be merged with and into
an existing Florida banking subsidiary of F.N.B.

In performing our analysis of the proposed merger, we have among other things:

1.   Reviewed the audited statements prepared by Hacker, Johnson, Cohen & Grieb,
     PA of Tampa, Florida, for the fiscal years ended 12/31/97, 12/31/96, and
     12/31/95.

2.   Reviewed the Call Reports of the Bank filed with the regulators reflecting
     the operations of the Bank for the periods ended 3/31/98, 12/31/97,
     12/31/96, and 12/31/95.

3.   Reviewed the Agreement and Plan of Merger dated April 6, 1998.

4.   Reviewed the budget for the Bank for the year 1998.

5.   Reviewed the four-year plan for the Bank (1997-2000).

6.   Reviewed other financial information concerning CHC.

7.   Compared the terms of the Merger Agreement with F.N.B. with the terms
     offered shareholders of comparable institutions in Florida in recent
     transactions.

8.   Reviewed the public information concerning the operations of F.N.B.


   185
Board of Directors
Page Two
May 15, 1998


9.   Examined CHC's market share in the Pinellas County market including other
     competitive banking institutions active in CHC's market are.

10.  Compared CHC's financial performance with other comparable banking
     institutions operating in Florida.

11.  Reviewed the financial condition of F.N.B. and the impact of the proposed
     transaction on the market price of the shares of F.N.B..

12.  Reviewed the price performance and trading activity in the shares of F.N.B.
     over the past six months.

In arriving at our opinion, we have relied upon the accuracy and completeness of
the information provided to us by CHC which we have used in the accompanying
analysis. We have not conducted an independent verification of such information
or performed an independent appraisal of CHC's assets and liabilities.

On April 3, 1998, Ewing delivered to the Board of Directors of CHC its
preliminary oral opinion as to the fairness, from a financial point of view, of
the terms offered by F.N.B., subject to Ewing's review of the final Merger
Agreement.

Based upon the accompanying analysis and our knowledge of and experience in the
valuation of Florida banks and their securities, it is our opinion that the
consideration to be paid by F.N.B. Corporation for the common shares of Citizens
Holding Corporation is fair, from a financial point of view, to the shareholders
of CHC.

The opinion of Allen C. Ewing & Co. ("Ewing") is directed to the Board of
Directors and does not constitute a recommendation to any shareholder as to how
such shareholder should vote at the shareholders' meeting held in connection
with the proposed transaction. Ewing has not been requested to opine as to, and
the opinion does not address, the Board's underlying business decision to
support and recommend the acquisition to the shareholders.

Very truly yours,


ALLEN C. EWING & CO.

Board of Directors
Citizens Holding Corporation

Clearwater, Florida  33755

Gentlemen:

The purpose of this letter is to reconfirm our fairness opinion as dated May 15,
1998 after considering the changes made by Citizens Holding Corporation ("CHC")
and F.N.B. Corporation ("F.N.B.") to the original Merger Agreement which are
incorporated in the First Amendment which was executed on June 30, 1998.

We have reviewed the terms of the First Amendment and analyzed how they will
effect the financial aspects of the proposed merger transaction between CHC and
F.N.B. Our analysis indicates that the terms of the First Amendment are
favorable to the terms of the Merger Agreement and will result in increased
compensation being paid to the CHC shareholders.

We confirm that it is our opinion that the terms of the Merger Agreement, as
modified by the First Amendment, will result in consideration to be paid by the
F.N.B. Corporation for the common shares of Citizens Holding Corporation that is
fair, from a financial point of view, to the shareholders of Citizens Holding
Corporation.

The opinion of Allen C. Ewing & Co. ("Ewing") is directed to the Board of
Directors and does not constitute a recommendation to any shareholder as to how
such shareholder should vote at the shareholders' meeting held in connection
with the proposed transaction. Ewing has not been requested to opine as to, and
the opinion does not address, the Board's underlying business decision to
support and recommend the acquisition to the shareholders.

Very truly yours,

ALLEN C. EWING & CO.

corporation by merger or share exchange of that issuer.
         (2) "Fair value," with respect to a dissenter's shares, means the value
of the shares as of the close of business on the day prior to the shareholders'
authorization date, excluding any appreciation or depreciation in anticipation
of the corporate action unless exclusion would be inequitable.
         (3) "Shareholders' authorization date" means the date on which the
shareholders' vote authorizing the proposed action was taken, the date on which
the corporation received written consents without a meeting from the requisite
number of shareholders in order to authorize the action, or, in the case of a
merger pursuant to s. 607.1104, the day prior to the date on which a copy of the
plan of merger was mailed to each shareholder of record of the subsidiary
corporation.

         607.1302 RIGHT OF SHAREHOLDERS TO DISSENT.--(1) Any shareholder of a
corporation has the right to dissent from, and obtain payment of the fair value
of his or her shares in the event of, any of the following corporate actions:
         (a) Consummation of a plan of merger to which the corporation is a
party:
         1.  If the shareholder is entitled to vote on the merger, or
         2.  If the corporation is a subsidiary that is merged with its parent
under s. 607.1104, and the shareholders would have been entitled to vote on
action taken, except for the applicability of s. 607.1104;
         (b) Consummation of a sale or exchange of all, or substantially all, of
the property of the corporation, other than in the usual and regular course of
business, if the shareholder is entitled to vote on the sale or exchange
pursuant to s. 607.1202, including a sale in dissolution but not including a
sale pursuant to court order or a sale for cash pursuant to a plan by which all
or substantially all of the net proceeds of the sale will be distributed to the
shareholders within 1 year after the date of sale;
         (c) As provided in s. 607.0902(11), the approval of a control-share
 acquisition;
         (d) Consummation of a plan of share exchange to which the corporation
is a party as the corporation the shares of which will be acquired, if the
shareholder is entitled to vote on the plan;
         (e) Any amendment of the articles of incorporation if the shareholder
is entitled to vote on the amendment and if such amendment would adversely
affect such shareholder by:
         1.  Altering or abolishing any preemptive rights attached to any of his
or her shares;
         2.  Altering or abolishing the voting rights pertaining to any of his
or her shares, except as such rights may be affected by the voting rights of new
shares then being authorized of any existing or new class or series of shares;
         3.  Effecting an exchange, cancellation, or reclassification of any of
his or her shares, when such exchange, cancellation, or reclassification would
alter or abolish the shareholder's voting rights or alter his or her percentage
of equity in the corporation, or effecting a reduction or cancellation of
accrued dividends or other arrearages in respect to such shares;
         4. Reducing the stated redemption price of any of the shareholder's
redeemable shares, altering or abolishing any provision relating to any sinking
fund for the redemption or purchase of any of his or her shares, or making any
of his or her shares subject to redemption when they are not otherwise
redeemable;
         5. Making noncumulative, in whole or in part, dividends of any of the
shareholder's preferred shares which had theretofore been cumulative;
         6. Reducing the stated dividend preference of any of the shareholder's
preferred shares; or
         7. Reducing any stated preferential amount payable on any of the
shareholder's preferred shares upon voluntary or involuntary liquidation; or
         f) Any corporate action taken, to the extent the articles of
incorporation provide that a voting or nonvoting shareholder is entitled to
dissent and obtain payment for his or her shares.
        (2) A shareholder dissenting from any amendment specified in paragraph
(1)(e) has the right to dissent only as to those of his or her shares which are
adversely affected by the amendment.



                                     



                                      D-1
   188

        (3) A shareholder may dissent as to less than all the shares registered
in his or her name. In that event, the shareholder's rights shall be determined
as if the shares as to which he or she has dissented and his or her other shares
were registered in the names of different shareholders.
        (4) Unless the articles of incorporation otherwise provide, this
section does not apply with respect to a plan of merger or share exchange or a
proposed sale or exchange of property, to the holders of shares of any class or
series which, on the record date fixed to determined the shareholders entitled
to vote at the meeting of shareholders at which such action is to be acted upon
or to consent to any such action without a meeting, were either registered on a
national securities exchange or designated as a national market system security
on an interdealer quotation system by the National Association of Securities
Dealers, Inc., or held of record by not fewer than 2,000 shareholders.
        (5) A shareholder entitled to dissent and obtain payment for his or her
shares under this section may not challenge the corporate action creating his or
her entitlement unless the action is unlawful or fraudulent with respect to the
shareholder or the corporation. (Last amended by Ch. 94- 327, L. '94, eff.

         607.1320 PROCEDURE FOR EXERCISE OF DISSENTERS' RIGHTS.--(1)(a) If a
proposed corporate action creating dissenters' rights under s. 607.1302 is
submitted to a vote at a shareholders' meeting, the meeting notice shall state
that shareholders are or may be entitled to assert dissenters' rights and be
accompanied by a copy of ss. 607.1301, 607.1302, and 607.1320.
A shareholder who wishes to assert dissenters' rights shall:
         1.       Deliver to the corporation before the vote is taken written
notice of the shareholder's intent to demand payment for his or her shares if
the proposed action is effectuated, and
         2. Not vote his or her shares in favor of the proposed action. A proxy
or vote against the proposed action does not constitute such a notice of intent
to demand payment.
         (b) If proposed corporate action creating dissenters' rights under s.
607.1302 is effectuated by written consent without a meeting, the corporation
shall deliver a copy of ss. 607.1301, 607.1302, and 607.1320 to each shareholder
simultaneously with any request for the shareholder's written consent or, if
such a request is not made, within 10 days after the date the corporation
received written consents without a meeting from the requisite number of
shareholders necessary to authorize the action.
         (2) Within 10 days after the shareholders' authorization date, the
corporation shall give written notice of such authorization or consent or
adoption of the plan of merger, as the case may be, to each shareholder who
filed a notice of intent to demand payment for his or her shares pursuant to
paragraph (1)(a) or, in the case of action authorized by written consent, to
each shareholder, excepting any who voted for, or consented in writing to, the
proposed action.
         (3) Within 20 days after the giving of notice to him or her, any
shareholder who elects to dissent shall file with the corporation a notice of
such election, stating the shareholder's name and address, the number, classes,
and series of shares as to which he or she dissents, and a demand for payment of
the fair value of his or her shares. Any shareholder failing to file such
election to dissent within the period set forth shall be bound by the terms of
the proposed corporate action. Any shareholder filing an election to dissent
shall deposit his or her certificates for certificated shares with the
corporation simultaneously with the filing of the election to dissent. The
corporation may restrict the transfer of uncertificated shares from the date the
shareholder's election to dissent is filed with the corporation.
         (4) Upon filing a notice of election to dissent, the shareholder shall
thereafter be entitled only to payment as provided in this section and shall not
be entitled to vote or to exercise any other rights of a shareholder. A notice
of election may be withdrawn in writing by the shareholder at any time before an
offer is made by the corporation, as provided in subsection (5), to pay for his
or her shares. After such offer, no such notice of election may be withdrawn
unless the corporation consents thereto. However, the right of such shareholder
to be paid the fair value of his or her shares shall cease, and the shareholder
shall be reinstated to have all his or her rights as a shareholder as of the
filing of his or her notice of election, including any intervening preemptive
rights and the right to payment of any intervening dividend or other
distribution or, if any such rights have expired or any such dividend or
distribution other than in cash has been completed, in lieu thereof, at the
election of the corporation, the fair value thereof in cash as determined by the
board as of the time of such expiration or 


                                      D-2


   189

completion, but without prejudice otherwise to any corporate proceedings that
may have been taken in the interim, if:
         (a) Such demand is withdrawn as provided in this section;
         (b) The proposed corporate action is abandoned or rescinded or the
shareholders revoke the authority to effect such action;
         (c) No demand or petition for the determination of fair value by a
court has been made or filed within the time provided in this section; or
         (d) A court of competent jurisdiction determines that such shareholder
is not entitled to the relief provided by this section.
         (5) Within 10 days after the expiration of the period in which
shareholders may file their notices of election to dissent, or within 10 days
after such corporate action is effected, whichever is later (but in no case
later than 90 days from the shareholders' authorization date), the corporation
shall make a written offer to each dissenting shareholder who has made demand as
provided in this section to pay an amount the corporation estimates to be the
fair value for such shares. If the corporate action has not been consummated
before the expiration of the 90-day period after the shareholders' authorization
date, the offer may be made conditional upon the consummation of such action.
Such notice and offer shall be accompanied by:
         (a) A balance sheet of the corporation, the shares of which the
dissenting shareholder holds, as of the latest available date and not more than
12 months prior to the making of such offer; and
         (b) A profit and loss statement of such corporation for the 12-month
period ended on the date of such balance sheet or, if the corporation was not in
existence throughout such 12-month period, for the portion thereof during which
it was in existence.
         (6) If within 30 days after the making of such offer any shareholder
accepts the same, payment for his or her shares shall be made within 90 days
after the making of such offer or the consummation of the proposed action,
whichever is later. Upon payment of the agreed value, the dissenting shareholder
shall cease to have any interest in such shares.
         (7) If the corporation fails to make such offer within the period
specified therefor in subsection (5) or if it makes the offer and any dissenting
shareholder or shareholders fail to accept the same within the period of 30 days
thereafter, then the corporation, within 30 days after receipt of written demand
from any dissenting shareholder given within 60 days after the date on which
such corporate action was effected, shall, or at its election at any time within
such period of 60 days may, file an action in any court of competent
jurisdiction in the county in this state where the registered office of the
corporation is located requesting that the fair value of such shares be
determined. The court shall also determine whether each dissenting shareholder,
as to whom the corporation requests the court to make such determination, is
entitled to receive payment for his or her shares. If the corporation fails to
institute the proceeding as herein provided, any dissenting shareholder may do
so in the name of the corporation. All dissenting shareholders (whether or not
residents of this state), other than shareholders who have agreed with the
corporation as to the value of their shares, shall be made parties to the
proceeding as an action against their shares. The corporation shall serve a copy
of the initial pleading in such proceeding upon each dissenting shareholder who
is a resident of this state in the manner provided by law for the service of a
summons and compliant and upon each nonresident dissenting shareholder either by
registered or certified mail and publication or in such other manner as is
permitted by law. The jurisdiction of the court is plenary and exclusive. All
shareholders who are proper parties to the proceeding are entitled to judgment
against the corporation for the amount of the fair value of their shares. The
court may, if it so elects, appoint one or more persons as appraisers to receive
evidence and recommend a decision on the question of fair value. The appraisers
shall have such power and authority as is specified in the order of their
appointment or an amendment thereof. The corporation shall pay each dissenting
shareholder the amount found to be due him or her within 10 days after final
determination of the proceedings. Upon payment of the judgment, the dissenting
shareholder shall cease to have any interest in such shares.
         (8) The judgment may, at the discretion of the court, include a fair
rate of interest, to be determined by the court.
         (9) The costs and expenses of any such proceeding shall be determined
by the court and shall be assessed against the corporation, but all or any part
of such costs and expenses may be apportioned and assessed as the court deems
equitable against any or all of the dissenting shareholders who are parties to
the proceeding, to whom the corporation has made an offer to pay for the shares,
if the court finds that the action of 






                                      D-3

   190

such shareholders in failing to accept such offer was arbitrary, vexatious, or
not in good faith. Such expenses shall include reasonable compensation for, and
reasonable expenses of, the appraisers, but shall exclude the fees and expenses
of counsel for, and experts employed by, any party. If the fair value of the
shares, as determined, materially exceeds the amount which the corporation
offered to pay therefor or if no offer was made, the court in its discretion may
award to any shareholder who is a party to the proceeding such sum as the court
determines to be reasonable compensation to any attorney or expert employed by
the shareholder in the proceeding.
         (10) Shares acquired by a corporation pursuant to payment of the agreed
value thereof or pursuant to payment of the judgment entered therefor, as
provided in this section, may be held and disposed of by such corporation as
authorized but unissued shares of the corporation, except that, in the case of a
merger, they may be held and disposed of as the plan of merger otherwise
provides. The shares of the surviving corporation into which the shares of such
dissenting shareholders would have been converted had they assented to the
merger shall have the status of authorized but unissued shares of the surviving
corporation. (Last amended by Ch. 93-281, L. '93, eff. 5-15-93).

                 PART II: INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Numbered Paragraph 6.b of the FNB Charter provides as follows:

         Directors and Officers of the Corporation shall be indemnified as of
right to the fullest extent now or hereafter 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
the Corporation or otherwise), arising out of their service to the Corporation
or to another organization at the request of the Corporation, or because of
their positions with the Corporation. Persons who are not Directors or Officers
of the Corporation may be similarly indemnified in respect of such service to
the extent authorized at any time by the Board of Directors of the Corporation.
The Corporation may purchase and maintain insurance to protect itself and any
such Director, Officer or other person against any liability, cost or expense
asserted against or incurred by him in respect of such service, whether or not
the Corporation would have the power to indemnify him against such liability by
law or under the provisions of this para graph. The provisions of this paragraph
shall be applicable to persons who have ceased to be Directors or Officers, and
shall inure to the benefit of the heirs, executors and administrators of persons
entitled to indemnity hereunder.

         Article IX of the FNB Bylaws provides that FNB shall indemnify each
director and officer of FNB and of its controlled subsidiaries made or
threatened to be made a party to any civil, criminal, administrative action,
suit or proceeding (whether brought by or in the name of FNB or otherwise)
arising out of such director's or officer's service to FNB or to another
organization at FNB'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 FNB in advance
of the final disposition of such action, suit or proceeding if an undertaking
(in form and scope satisfactory to FNB) shall have been furnished to FNB 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. FNB 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 PBCL 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 persons 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 


                                      II-1


   192


of the corporation and, with respect to any criminal proceeding, had reasonable
cause to believe that his conduct was unlawful.

         Under Section 1744 of the PBCL, any such indemnification (unless
ordered by a court) shall be made by the corporation only as authorized in a
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 PBCL, 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 PBCL 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 or her 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.


                                      II-2

   193



         The foregoing is only a general summary of certain aspects of
Pennsylvania law dealing with 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 as exhibit
99.3 of this registration statement.

ITEM 22.  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;

                           (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 volume of securities offered (if the total dollar

                  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

                           (iii) To include any material information with
                  respect to the plan of distribution not previously disclosed
                  in the Registration Statement or any material change in such
                  information 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) 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.

         (c) The undersigned Registrant hereby undertakes to deliver or cause to
be delivered with the prospectus, to each person to whom the prospectus is sent
or given, the latest annual report, to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X is not set forth in the prospectus, to deliver, or cause to be
delivered to each person to whom the prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.

         (d) (1) The undersigned Registrant hereby undertakes as follows: that
         prior to any public reoffering of the securities registered hereunder
         through use of a prospectus which is a part of this Registration
         Statement, by any person or party who is deemed to be an underwriter
         within the meaning of Rule 145(c), the issuer undertakes that such
         reoffering prospectus will contain the information called for by the
         applicable registration form with respect to reofferings by persons who
         may be deemed underwriters, in addition to the information called for
         by the other items of the applicable form.

                  (2) The Registrant undertakes that every prospectus (i) that
         is filed pursuant to paragraph (1) immediately preceding, or (ii) that
         purports to meet the requirements of Section 10(a)(3) of the Securities
         Act and is used in connection with an offering of securities subject to
         Rule 415, will be filed as a part of an amendment to the Registration
         Statement and will not be used until such amendment is effective, and
         that, for purposes 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.

         (e) 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 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.

         (f) The undersigned Registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

         (g) The undersigned Registrant hereby undertakes to supply by means of
a post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
