ITEM 5.  OTHER EVENTS.

         West Coast Bancorp, Inc. a Florida corporation ("West Coast"), F.N.B.
Corporation, a Pennsylvania corporation ("FNB"), and Southwest Banks, Inc., a
Florida corporation which will be a wholly-owned subsidiary of FNB, have
entered into an Agreement and Plan of Merger dated November 15, 1996 ("Merger
Agreement") pursuant to which, among other things, West Coast will be merged
with and into Southwest, with Southwest as the surviving corporation (the
"Merger").  A copy of the Merger Agreement is attached hereto as Exhibit 2.1
and is incorporated herein by reference.  The press release describing the
proposed Merger is attached hereto as Exhibit 99.1.

         FNB is a Pennsylvania-based bank holding company registered under the
Bank Holding Company Act of 1956, as amended (the "BHCA"), with total assets of
approximately $1.7 billion.  Pursuant to the terms of the Merger Agreement,
each West Coast common share, $1.00 par value per share ("West Coast Common
Shares"), other than certain shares owned by FNB or its subsidiaries, issued
and outstanding immediately prior to the Effective Time (as defined in the
Merger Agreement) of the Merger will be converted into 0.794 shares of FNB
common stock, $2.00 par value per share ("FNB Common Stock").  No fractional
shares of FNB Common Stock will be issued in the Merger, and West Coast
shareholders who otherwise would be entitled to receive a fractional share of
FNB Common Stock will receive a cash payment in lieu thereof.  Outstanding
warrants and options held by employees and directors of West Coast will be
converted into FNB options at the same exchange ratio.  In addition, the Merger
Agreement provides that through the Effective Time, not only may West Coast
continue to declare and pay regular quarterly dividends to its shareholders, it
may increase the amount of its dividend to that amount of dividends which is
currently paid by FNB to its shareholders, as adjusted by the exchange ratio.

         The Merger is intended to be a tax-free reorganization under the
Internal Revenue Code of 1986, as amended, and to be accounted for under the
pooling of interest method.

         FNB and Southwest entered into an Agreement and Plan of Merger dated
February 2, 1996 ("FNB/Southwest Merger Agreement") pursuant to which Southwest
will be merged with and into a wholly-owned FNB subsidiary on or about January
19, 1997, with Southwest as the surviving corporation.  As a result of the
FNB/Southwest Merger, Southwest will become a wholly-owned subsidiary of FNB.
The Merger between Southwest and West Coast which is the subject of the Merger
Agreement is expected to take place after consummation of the FNB/Southwest
Merger.  If the FNB/Southwest Merger is not completed prior to closing of the
Merger, the Merger Agreement provides for the Merger of West Coast into another
wholly-owned FNB subsidiary.

         Consummation of the Merger is subject to a number of conditions,
including: (i) receipt of the approval of a majority of the outstanding West
Coast Common Shares, (ii) receipt of all requisite governmental and regulatory
approvals (including approval of the Board of Governors of the Federal Reserve
System), (iii) West Coast's receipt of a fairness opinion from its investment
banker within five days from the date of its proxy statement, (iv) effectiveness
of a registration statement to be filed by FNB with the Securities and Exchange 
Commission ("SEC") with respect to the FNB Common Stock to be issued in the 
Merger, (v) receipt of a letter from FNB's independent public accountants that 
the Merger will be accounted as a pooling of interests, (vi) receipt of a 
favorable opinion of counsel with respect to the tax free nature of certain 
aspects of the Merger, and (vii) the satisfaction of certain other closing 
conditions customary in a transaction of this type.  The Merger Agreement 
provides that the Board of Directors of Southwest's subsidiary banks after the 
Merger will include current members of the West Coast Board of Directors for at 
least one year.  The Merger Agreement is subject to termination under certain 
circumstances, including if the Merger is not consummated by September 30, 1997.
In addition,





                                       2

West Coast may terminate the Merger Agreement if 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 day period ending on the fifth business day prior
to the Effective Time is less than $20.625.

         Concurrently with the execution of the Merger Agreement, West Coast
and FNB entered into a Stock Option Agreement (the "FNB Option") pursuant to
which West Coast has granted FNB an option to purchase up to 426,991 West Coast
Common Shares at a price, subject to certain customary anti-dilution rights and
adjustments, of $15.00 per share (representing approximately 19.9% of the
outstanding shares on a fully diluted basis assuming exercise of all the
currently existing outstanding warrants and options to purchase West Coast
Common Shares).  The FNB Option was granted by West Coast as an inducement and
condition to FNB's willingness to enter into the Merger Agreement.  A copy of
the FNB Option is an exhibit to the Merger Agreement and is attached hereto as
Exhibit 10.1 and is incorporated herein by reference.

         The FNB Option is exercisable only upon the occurrence of an "Initial
Triggering Event" (as defined in the FNB Option) and a "Subsequent Triggering
Event" (as defined in the FNB Option) prior to termination of the FNB Option.

         The FNB Option will expire upon the occurrence of any of the following:
(i) the Effective Time of the Merger, (ii) the termination of the Merger 
Agreement if termination occurs prior to an Initial Triggering Event (unless 
termination was due to (a) FNB's inability to satisfy a condition to closing, 
(b) failure to receive the requisite West Coast shareholders approval following 
a favorable recommendation by the West Coast Board of Directors, or (c) the 
withdrawal of the fairness opinion of West Coast's investment banker, in which 
case the FNB Option will expire upon termination of the Merger Agreement 
notwithstanding the occurrence of a Initial Triggering Event), (iii) the passage
of 12 months after termination of Merger Agreement if termination follows the 
occurrence of an Initial Triggering Event not subject to the parenthetical 
above, or (iv) such other date as the parties may agree.

         An Initial Triggering Event, the occurrence of which serves as a
condition precedent to exercise of the FNB Option and, under certain
circumstances, serves to extend the term of the FNB Option beyond a termination
of the Merger Agreement, generally includes (i) West Coast, without the prior
written consent of FNB, entering into or its Board of Directors recommending
shareholder approval of, an agreement with a third party to effect any of the
following transactions (each an "Acquisition Transaction"): (a) a merger,
consolidation, or a similar transaction involving West Coast or any of its
subsidiaries, (b) a purchase, lease, or other acquisition of all or
substantially all of the assets or deposits of West Coast of any of its
subsidiaries, or (c) 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 West Coast or any of its subsidiaries; (ii)
any person (excluding the officers and directors of West Coast) other than FNB,
acquiring beneficial ownership or the right to acquire beneficial ownership of
15% or more of the outstanding West Coast Common Shares; (iii) failure of West
Coast shareholders to approve the Merger Agreement after withdrawal of the West
Coast Board of Directors' recommendation that shareholders approve the Merger
which withdrawal occurs following its authorization, recommendation, or a
public proposal of an intent or authorization to engage in an Acquisition
Transaction with a third party; (iv) receipt of a bona fide proposal from a
third party having economic value at least equal to the Merger, (v) willful
breach of the Merger Agreement by West Coast in anticipation of engaging in an
Acquisition Transaction with a third party; or (vi) filing of application or
notice by third party with, and which has been accepted by, the Federal Reserve
Board or other banking authority seeking approval to engage in an Acquisition
Transaction.





                                       3
<PAGE>   4

         Notwithstanding the occurrence of an Initial Triggering Event, the FNB
Option will become exercisable only if a Subsequent Triggering Event shall
occur thereafter but prior to termination of the FNB Option.  A Subsequent
Triggering Event generally includes any acquisition by a third party of 25% or
more of the outstanding West Coast Common Shares or any Acquisition Transaction
of the type referred to in clause (i) of the preceding paragraph, except that
the percentage referred to in clauses (i)(c) shall be 25%.

         As more fully set forth in the FNB Option, FNB (or a subsequent holder
of an FNB Option or the shares issued thereunder) has the right under specified
circumstances to require West Coast to repurchase the FNB Option or such
shares.  West Coast's ability to engage in a subsequent pooling of interests
transaction may be adversely affected if holders of the FNB Option exercise
such rights.  In addition, the FNB Option provides holders of the FNB Option
with certain rights to require West Coast to register the West Coast Common
Shares acquired by or issuable upon the exercise of the FNB Option under the
Securities Act of 1933, as amended.

         The foregoing summary of the contents of the Merger Agreement and the
FNB Option is qualified in its entirety by reference to Exhibits 2.1 and 10.1
hereto.

         On November 15, 1996, West Coast announced the execution of the
definitive Merger Agreement with FNB and its general terms.

                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") is made and
entered into as of November 15, 1996, 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, which will be a wholly owned
subsidiary of FNB on or about January 19, 1997 pursuant to the terms of that
certain Agreement and Plan of Merger dated February 2, 1996 among Southwest,
FNB and Southwest Affiliation Corporation, a wholly owned subsidiary of FNB
(the "FNB/Southwest Merger"); and WEST COAST BANCORP, INC. ("West Coast"), a
Florida corporation having its principal office located in Cape Coral, Florida.

                                    PREAMBLE

         The Boards of Directors of West Coast 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
West Coast by FNB pursuant to the merger of West Coast with and into Southwest
(the "Merger").  In the event that the FNB/Southwest Merger has not been
consummated prior to the effective time of the Merger, FNB will substitute
another of its wholly owned subsidiaries as a party to this Agreement in place
of Southwest.  At the effective time of such Merger, the outstanding shares of
the capital stock of West Coast shall be converted into the right to receive
shares of the common stock of FNB (except as provided herein). As a result,
shareholders of West Coast shall become shareholders of FNB. The transactions
described in this Agreement are subject to the approvals of the shareholders of
West Coast, 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 (as hereinafter defined) 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.

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

   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, West Coast shall be merged with and into Southwest in
accordance with the provisions of the Florida Business Corporation Act (the
"FBCA").  The separate corporate existence of West Coast shall thereupon cease,
and Southwest shall be the Surviving Corporation resulting from the Merger and
shall continue to be governed by the Laws of the State of Florida. The Merger





                                       1
<PAGE>   7

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 West Coast, FNB and Southwest.

         1.2 Time and Place of Closing.  The Parties shall use their reasonable
efforts to cause the closing of the transactions contemplated by this Agreement
to take place at 9:00 A.M. on or before the fifth business day (as designated
by FNB) but not prior to the second business day following the Effective Time,
or at such other time as the Parties, acting through their chief executive
officers or chief financial officers, may mutually agree. The place of closing
shall be at such location as may be mutually agreed upon by the Parties.

         1.3 Effective Time.  The Merger and other transactions contemplated by
this Agreement shall become effective on the date and at the time 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 of the State of Florida or at such later date and time as is agreed
upon by the Parties as specified in the Florida Articles of Merger (the
"Effective Time"). Subject to the terms and conditions hereof, unless otherwise
mutually agreed upon in writing by each Party, the Effective Time shall occur
on the last to occur of (i) the effective date (including expiration of any
applicable waiting period) of the last required Consent of any Regulatory
Authority having authority over and approving or exempting the Merger if such
action is required, and (ii) the date on which the shareholders of West Coast
approve this Agreement to the extent such approval is required by applicable
Law.

         1.4 Execution of Stock Option Agreement.  Concurrently with the
execution of this Agreement and as a condition thereto, West Coast 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 Incorporation of Southwest in effect at the Effective Time shall be the
Articles of Incorporation of the Surviving Corporation until otherwise amended
or repealed.

         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.

         2.3 Directors.  Upon the Effective Time, the directors of West Coast
shall be elected as directors for a term of one year of a subsidiary bank of
FNB having its headquarters in Lee County,  Florida and FNB shall cause
directors fees to be paid to such individuals for such term in an amount at
least equal to the higher of the amount currently paid to the directors of the
Southwest Subsidiaries or the amount currently paid to the West Coast
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 West Coast, or the shareholders of any of the
foregoing, the shares of the constituent corporations shall be converted as
follows:





                                       2
<PAGE>   8


                 (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.

                 (c) Each of the West Coast Common Shares (excluding shares to
         be canceled pursuant to Section 3.3 of the Agreement) issued and
         outstanding at the Effective Time shall cease to be outstanding and
         shall be converted into the right to receive and exchanged for .794
         shares of FNB Common Stock (the "Exchange Ratio").

         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.

         3.3 Shares Held by West Coast or FNB.  Each of the West Coast Common
Shares held by West Coast or by any FNB Company, in each case other than those
West Coast Common Shares held 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.

         3.4 Fractional Shares.  Notwithstanding any other provision of this
Agreement, each holder of West Coast 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 value" of one share of FNB Common Stock at the Effective Time.
The market value of one share of FNB Common Stock at the Effective Time shall
be the average of the high bid and low asked prices of such common stock in the
over-the-counter market, as reported by Nasdaq (or, if not reported thereby,
any other authoritative source selected by FNB) on the last trading day
preceding the Effective Time. 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 Conversion of Stock Options, Warrants, and Other Rights.

         (a)     At the Effective Time, each award, option, warrant, or other
right to purchase or acquire West Cost Common Shares pursuant to stock awards,
stock options, warrant agreements, or stock appreciation rights ("West Coast
Options") granted by West Coast under the West Coast Stock Plans or otherwise
(including, without limitation, those warrants issued to certain officers and
directors of West Coast), which are outstanding at the Effective Time and as
were previously listed and described in Section 3.5 of the West Coast
Disclosure Memorandum, whether or not vested or exercisable, shall be converted
into and become rights with respect to FNB Common Stock, and FNB shall assume
each West Coast Option, in accordance with the terms of the West Coast Stock
Plan and 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 West Coast and the committee of West Coast's
Board of Directors (including, if applicable, the entire Board of Directors of
West Coast) administering such West Coast Stock Plan, (ii) each West Coast
Option assumed by FNB may be exercised solely for shares of FNB Common Stock
(or cash in the case of




                                       3
<PAGE>   9

stock appreciation rights), (iii) the number of shares of FNB Common Stock
subject to such West Coast Option shall be equal to the number of shares of
West Coast Common Shares subject to such West Coast Option immediately prior to
the Effective Time multiplied by the Exchange Ratio, and (iv) the per share
exercise price (or similar threshold price, in the case of stock awards) under
each such West Coast Option shall be adjusted by dividing the per share
exercise (or threshold) price under each such West Coast 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 West Coast Options and
any fraction of a share of FNB Common Stock that otherwise would be subject to
a converted West Coast Option shall represent the right to receive a cash
payment equal to the product of such fraction and the difference between the
"market value" as defined in Section 3.4 of one share of FNB Common Stock and
the per share exercise price of such right.  In addition, notwithstanding the
provisions of clauses (iii) and (iv) of the first sentence of this Section
3.5(a), each West Coast 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. FNB agrees 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 West Coast Stock Plan an appropriate notice
setting forth such participant's rights pursuant thereto and the grants
pursuant to such West Coast 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 West Coast Stock Plan to ensure, to the extent required by,
and subject to the provisions of, such West Coast Stock Plan, the West Coast
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 delivery upon
exercise of West Coast Options assumed by FNB 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 options and shall use its reasonable efforts to maintain
the effectiveness of such registration statements (and maintain the current
status of the prospectus or prospectuses contained therein) for so long as such
options remain outstanding.  With respect to those individuals who subsequent
to the Merger will be subject to the reporting requirements under Section 16(a)
of the Exchange Act, where applicable, FNB shall administer the West Coast
Stock Plan assumed pursuant to this Section 3.5 in a manner that complies with
Rule 16b-3 promulgated under the Exchange Act to the extent the West Coast
Stock Plan complied with such rule prior to the Merger.

         (c)     All restrictions or limitations on transfer with respect to
West Coast Common Shares awarded under the West Coast Stock Plans, 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 with respect to shares of FNB Common
Stock into which such restricted stock is converted pursuant to Section 3.1 of
this Agreement.

                               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





                                       4

Common Stock and cash in such amounts necessary to provide all consideration
required to be exchanged by FNB for West Coast 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 West Coast appropriate
transmittal materials (which shall specify that delivery shall be effected, and
risk of loss and title to the certificates theretofore representing shares of
West Coast Common Shares shall pass, only upon proper delivery of such
certificates to the Exchange Agent). After the Effective Time, each holder of
shares of West Coast 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 West
Coast 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 West Coast Common
Shares is entitled as a result of the Merger until such holder surrenders such
holder's certificate or certificates representing the West Coast Common Shares
for exchange as provided in this Section 4.1. The certificate or certificates
of West Coast 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 West Coast 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 West Coast Shareholders.  At the Effective Time,
the stock transfer books of West Coast shall be closed as to holders of West
Coast Common Shares immediately prior to the Effective Time and no transfer of
West Coast 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 West
Coast Common Shares (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 West Coast
in respect of such West Coast 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 West Coast shall be
entitled to vote at any meeting of FNB stockholders the number of shares of FNB
Common Stock into which their respective West Coast Common Shares are
converted, regardless of whether such holders have exchanged their certificates
representing West Coast 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 West Coast 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 West Coast 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 West
Coast for six months after the Effective Time shall be paid to FNB.  Any
shareholders of West Coast 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 West Coast
Common Share such shareholder holds as determined pursuant to this Agreement,
in each case, without any interest thereon.

                                   ARTICLE 5

                  REPRESENTATIONS AND WARRANTIES OF WEST COAST

         West Coast hereby represents and warrants to FNB as follows:

         5.1 Organization, Standing, and Power.  West Coast 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.
West Coast 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 West Coast and its Subsidiaries
taken as a whole.

         5.2 Authority; No Breach by Agreement.

         (a) West Coast 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 West Coast, to perform its obligations
under this Agreement and consummate the transactions contemplated hereby. The
execution, delivery, and performance of this Agreement by West Coast and the
consummation by West Coast 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 West Coast, subject to the approval of
this Agreement by its shareholders as contemplated by Section 8.1 hereof.
Subject to such requisite shareholder approval (and assuming due authorization,
execution, and delivery by FNB and Surviving Corporation), this Agreement
represents a legal, valid, and binding obligation of West Coast, enforceable
against West Coast 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
affirmative vote of the holders of a majority of the outstanding West Coast
Common Shares is the only shareholder vote necessary to approve this Agreement
and the transactions contemplated hereby.  The West Coast Board of Directors
has received from Advest, Inc. 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 West Coast Common Shares.

         (b) Except as disclosed in Section 5.2(b) of the West Coast Disclosure
Memorandum, neither the execution and delivery of this Agreement by West Coast,
nor the consummation by West Coast of the transactions contemplated hereby, nor
compliance by West Coast with any of the provisions hereof, will (i) conflict
with or result in a breach of any provision of West Coast's Articles of
Incorporation or Bylaws,





                                       6

or, (ii) constitute or result in a default under, or result in the creation of
any Lien on any material Asset of any West Coast Company under, or require any
consent pursuant to, any Contract or Permit of any West Coast 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
West Coast and its Subsidiaries taken as a whole, or, (iii) subject to receipt
of the requisite Consents referred to in Sections 9.1(a), (b) and (c) of this
Agreement, violate any Order or, to its knowledge, any law applicable to any
West Coast Company or any of their respective material Assets which will have a
Material Adverse Effect on West Coast and its 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 Small Business Administration,
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  West Coast and its Subsidiaries, taken as a whole; no notice to,
filing with, or Consent of, any public body or authority is necessary for the
consummation by West Coast of the Merger and the other transactions
contemplated in this Agreement.

         (a) The authorized capital stock of West Coast consists of (i)

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 the West Coast 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 West Coast or any of its Subsidiaries from West
Coast or any of its Subsidiaries under any West Coast Benefit Plan or
otherwise, (ii) increase any benefits otherwise payable under any West Coast
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 West Coast and its Subsidiaries on a consolidated basis.

         5.13 Material Contracts.  Except as disclosed in Section 5.13 of the
West Coast Disclosure Memorandum, none of the West Coast Companies is 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 $100,000, (ii) any Contract relating
to the borrowing of money by any West Coast Company or the guarantee by any

Contracts evidencing deposit liabilities, purchases of federal funds,
fully-secured repurchase agreements, and Federal Home Loan Bank advances of
depository institution Subsidiaries, trade payables, and Contracts relating to
borrowings or guarantees made in the ordinary course of business), and (iii)

respect to each West Coast Contract and except as disclosed in Section 5.13 of
the West Coast Disclosure Memorandum: (i) each West





                                       12

Coast Contract is in full force and effect; (ii) no West Coast Company is in
default thereunder, other than defaults which are not reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect on West
Coast; (iii) no West Coast Company has repudiated or waived any material
provision of any such West Coast Contract; and (iv) no other party to any such
Contract is, to the Knowledge of West Coast, in default in any material

West Coast Disclosure Memorandum, there is no Litigation instituted or pending,
or, to the Knowledge of West Coast, 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 West Coast 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 West Coast, nor are there any Orders of any Regulatory

which names a West Coast Company as a defendant or cross-defendant and where
the estimated maximum exposure is $25,000 or more.

         5.15 Reports.  Since January 1, 1996, each West Coast 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 on West Coast 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 or promulgated by the SEC. As of its respective date, no such report
or document contained any untrue statement of a material fact or omitted 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 is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on West Coast and its Subsidiaries taken
as a whole.

         5.16 Statements True and Correct.  None of the information supplied or
to be supplied by any West Coast 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 West Coast Company or any Affiliate thereof for inclusion in
the Proxy Statement to be mailed to West Coast's shareholders in connection
with the Shareholders' Meeting, and any other documents to be filed by a West
Coast 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 West Coast, 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

Shareholders' Meeting. All documents that any West Coast 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 West
Coast, neither West Coast 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 West Coast 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 Articles of Incorporation Provisions.  Each West Coast Company
has taken all action so that the entering into this Agreement and the
consummation of the Merger and the other transactions contemplated by this
Agreement do not and will not result in any super-majority voting requirement
or the grant of any rights to any Person under the Articles of Incorporation,
Bylaws, or other governing instruments of any West Coast Company or restrict or
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 West Coast
Company that may be directly or indirectly acquired or controlled by it.

         5.20 Derivatives Contracts.  Except as disclosed in Section 5.20 of
the West Coast Disclosure Memorandum, neither West Coast 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

except for those Derivatives Contracts set forth in Section 5.20 of the West
Coast Disclosure Memorandum.

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

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

regulations of the SEC with respect thereto, was prepared in accordance with
GAAP applied on a consistent basis throughout the periods involved (except as

<PAGE>   22

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.

as disclosed in the FNB Financial Statements delivered prior to the date of
this Agreement, (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 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, 1995, 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.

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.  FNB is 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 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





                                       17
<PAGE>   23

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.

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

time such documents are filed, and with respect to the Proxy Statement, when
first mailed to the shareholders of West Coast, be false or misleading with
respect to any material fact, or omit to state any material fact necessary to

of any fact or circumstance that is reasonably likely to (i) prevent the
transactions contemplated hereby, including the Merger, from qualifying as a

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

contemplated hereby do not and will not result in any super-majority voting
requirements or the




                                       26

grant of any rights to any Person under the Articles of Incorporation, Bylaws,
or other governing instruments of any West Coast Company or restrict or 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 West Coast Company
that may be directly or indirectly acquired or controlled by it.

         8.14 Agreement of Affiliates.  West Coast has disclosed in Section
8.14 of the West Coast Disclosure Memorandum all Persons whom it reasonably
believes are "affiliates" of West Coast for purposes of Rule 145 under the 1933
Act. West Coast shall use its reasonable efforts to cause each such Person to
deliver to FNB not later than 30 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 shares of
West Coast 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 West Coast 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 West Coast in exchange for shares of West
Coast Common Shares shall not be transferable until such time as financial
results covering at least 30 days of combined operations of FNB and West Coast
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 8.11
(and FNB shall be entitled to place restrictive legends upon certificates for
shares of FNB Common Stock issued to affiliates of West Coast pursuant to this
Agreement to enforce the provisions of this Section 8.11). 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.  Following the Effective Time, FNB shall
provide generally to officers and employees of the West Coast Companies,
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 West Coast or those currently provided by the FNB
Companies to their similarly situated officers and employees; provided, that,
for a period of 12 months after the Effective Time, FNB shall provide generally
to officers and employees of West Coast Companies severance benefits in
accordance with the policies of Southwest which include a payment to terminated
officers and employees of West Coast equal to one week's pay for each year of
service.  For purposes of participation and vesting (but not benefit accrual
under any employee benefit plans of FNB and its subsidiaries other than the
West Coast Benefit Plans) under such employee benefit plans, the service of the
employees of the West Coast Companies prior to the Effective Time shall be
treated as service with a FNB Company participating in such employee benefit
plans.

         8.16 Employment Contracts of Certain Officers of West Coast.  FNB
shall provide Messrs. Geml, Panicaro and Delmotte new FNB employment contracts
with such terms and conditions as shall be negotiated between the parties, in
exchange for the cancellation by such officers of their existing West Coast
employment contracts and corresponding severance pay agreements.  In the event
any of such officers elect not to enter into such proposed new FNB employment
agreements, FNB shall honor the severance pay agreement in the existing West
Coast employment agreement of such officer.

         8.17 Indemnification.

         (a) FNB shall, and shall cause the Surviving Corporation (and its
successors and assigns) to, indemnify, defend, and hold harmless each person
who is now, or has at anytime prior to the date hereof, or who becomes prior to
the Effective Time, an officer, director, employee, or agent of West Coast or
its Subsidiaries (each, an "Indemnified Party"), after the Effective Time
against any and all costs or expenses (including reasonable attorneys' fees),
judgments, fines, penalties, losses, claims, damages, liabilities, and amounts
paid in settlement in connection with any claim, action, suit, proceeding, or
investigation, whether civil, criminal, administrative, or investigative,
arising out of or pertaining to any action or omission occurring on or prior to
the Effective Time (including, without limitation, the transactions
contemplated by this Agreement) to the fullest extent then permitted under
Florida law and by the Articles of Incorporation and Bylaws of West Coast as in
effect on the date hereof, including provisions relating to advances of
expenses incurred in the defense of any action or suit. Without limiting the
foregoing, in any case in which approval by the Surviving Corporation is
required to effectuate any indemnification, FNB shall cause the Surviving
Corporation to direct, at the election of the Indemnified Party, that the
determination of any such approval shall be made by independent counsel
selected by the Indemnified Party. FNB shall, and shall cause the Surviving
Corporation, to apply such rights of indemnification in good faith and to the
fullest extent permitted by applicable law.

         (b) 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 8.17.

         (c) The provisions of this Section 8.17 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.

         8.18 Listing of Shares on Nasdaq. FNB undertakes, prior to the
Effective Time, to cause the shares of FNB Common Stock to be issued pursuant
to the Merger to be listed on the Nasdaq Small Cap Market, or such other
exchange or Nasdaq market on which the FNB Common Stock trades at the Effective
Time.

                                   ARTICLE 9

               CONDITIONS PRECEDENT TO OBLIGATIONS TO CONSUMMATE

         9.1 Conditions to Obligations of Each Party.  The respective
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 West Coast
         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




                                       28
<PAGE>   34

         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 the filing of 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 West Coast Disclosure Memorandum) or for 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.

                 (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 West Coast 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 and Russell, LLP 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 West Coast Common Shares for FNB Common
         Stock will not give rise to gain or loss to the shareholders of West
         Coast 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 West Coast and
         FNB reasonably satisfactory in form and substance to such counsel.

         9.2 Conditions to Obligations of FNB.  The obligations of FNB 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 FNB pursuant to Section 11.7(a) of this Agreement:

                 (a) Representations and Warranties.  For purposes of this
         Section 9.2(a), the accuracy of the representations and warranties of
         West Coast set forth in this Agreement shall be assessed as of the
         date of this Agreement and as of the Effective Time with the same
         effect as though all such





                                       29
<PAGE>   35

         representations and warranties had been made on and as of the
         Effective Time (provided that representations and warranties which are
         confined to a specified date shall speak only as of such date). The
         representations and warranties of West Coast set forth in Section 5.3
         of this Agreement shall be true and correct (except for inaccuracies
         which are de minimus in amount). The representations and warranties of
         West Coast set forth in Sections 5.17, 5.18, 5.19, and 5.20 of this
         Agreement shall be true and correct in all material respects. There
         shall not exist inaccuracies in the representations and warranties of
         West Coast set forth in this Agreement (including the representations
         and warranties set forth in Sections 5.3, 5.17, 5.18, 5.19, and 5.20)
         such that the aggregate effect of such inaccuracies has, or is
         reasonably likely to have, a Material Adverse Effect on West Coast;
         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.

                 (b) Performance of Agreements and Covenants.  Each and all of
         the agreements and covenants of West Coast to be performed and
         complied with pursuant to this Agreement and the other agreements
         contemplated hereby prior to the Effective Time shall have been duly
         performed and complied with in all material respects.

                 (c) Certificates.  West Coast shall have delivered to FNB (i)
         a certificate, dated as of the Effective Time and signed on its behalf
         by its chief executive officer and its chief financial officer, to the
         effect that the conditions of its obligations set forth in Section
         9.2(a) and 9.2(b) of this Agreement have been satisfied, and (ii)
         certified copies of resolutions duly adopted by West Coast's Board of
         Directors and shareholders evidencing the taking of all corporate
         action necessary to authorize the execution, delivery, and performance
         of this Agreement, and the consummation of the transactions
         contemplated hereby, all in such reasonable detail as FNB and its
         counsel shall request.

                 (d) Affiliates Agreements.  FNB shall have received from each
         affiliate of West Coast the affiliates letter referred to in Section
         8.14 of this Agreement, to the extent necessary to assure in the
         reasonable judgment of FNB that the transactions contemplated hereby
         will qualify for pooling-of- interests accounting treatment.

         9.3 Conditions to Obligations of West Coast.  The obligations of West
Coast 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 West Coast pursuant to Section 11.7(b)
of this Agreement:

                 (a) Representations and Warranties.  For purposes of this
         Section 9.3(a), the accuracy of the representations and warranties of
         FNB set forth in this Agreement shall be assessed as of the date of
         this Agreement and as of the Effective Time with the same effect as
         though all such representations and warranties had been made on and as
         of the Effective Time (provided that representations and warranties
         which are confined to a specified date shall speak only as of such
         date). The representations and warranties of FNB set forth in Section
         6.3 of this Agreement shall be true and correct (except for
         inaccuracies which are de minimus in amount). The representations and
         warranties of FNB set forth in Section 6.11 of this Agreement shall be
         true and correct in all material respects. There shall not exist
         inaccuracies in the representations and warranties of FNB set forth in
         this Agreement (including the representations and warranties set forth
         in Sections 6.3 and 6.11) such that the aggregate effect of such
         inaccuracies has, or is reasonably likely to have, a Material Adverse
         Effect on FNB; provided that, for purposes of this sentence only,
         those representations and warranties





                                       30
<PAGE>   36

         which are qualified by references to "material" or "Material Adverse
         Effect" shall be deemed not to include such qualifications.

                 (b) Performance of Agreements and Covenants.  Each and all of
         the agreements and covenants of FNB to be performed and complied with
         pursuant to this Agreement and the other agreements contemplated
         hereby prior to the Effective Time shall have been duly performed and
         complied with in all material respects.

                 (c) Certificates.  FNB shall have delivered to West Coast (i)
         a certificate, dated as of the Effective Time and signed on its behalf
         by its chief executive officer and its chief financial officer, to the
         effect that the conditions of its obligations set forth in Section
         9.3(a) and 9.3(b) of this Agreement have been satisfied, and (ii)
         certified copies of resolutions duly adopted by FNB's Board of
         Directors evidencing the taking of all corporate action necessary to
         authorize the execution, delivery, and performance of this Agreement,
         and the consummation of the transactions contemplated hereby, all in
         such reasonable detail as Southwest and its counsel shall request.

                 (d) Fairness Opinion.  West Coast shall have received from
         Advest, Inc. a letter, dated not more than five business days prior to
         the date of the Proxy Statement, to the effect that, in the opinion of
         such firm, the Exchange Ratio plus the payment of the dividends to
         West Coast Shareholders pursuant to Section 8.6 hereof is fair, from a
         financial point of view, to the holders of West Coast Common Shares.

                 (e) Payment of Consideration.  FNB shall have delivered to
         Exchange Agent the consideration to be paid to holders of the West
         Coast Common Shares pursuant to Sections 3.1 and 3.4 of this
         Agreement.

                 (f) Price Condition.  The Average Market Price of a share of
         FNB Common Stock shall not be less than $20.625.

                 (g) Opinion of Counsel.  West Coast shall have received a
         written opinion of Smith, Gambrell & Russell, LLP counsel to FNB,
         dated as of the Effective Time, with respect to such matters and in
         such form as shall be agreed upon between such firm and West Coast.

                                   ARTICLE 10

                                  TERMINATION

         10.1 Termination.  Notwithstanding any other provision of this
Agreement, and notwithstanding the approval of this Agreement by the
shareholders of West Coast, 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 West Coast; or

                 (b) By the Board of Directors of either FNB or West Coast
         (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(a) of this Agreement in
         the case of West Coast 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



                                       31
<PAGE>   37

         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(a) of this Agreement in the case of
         West Coast and Section 9.3(a) of this Agreement in the case of FNB; or

                 (c) By the Board of Directors of either FNB or West Coast 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 West Coast 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  West
         Coast 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 West Coast in
         the event that the Merger shall not have been consummated by September
         30, 1997, 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

                 (f) By FNB in the event dissenters' rights are claimed,
         pursuant to the applicable provisions of the FBCA, by persons owning
         in the aggregate more than 10% of the issued and outstanding West
         Coast Common Shares; or

                 (g) By West Coast, if its Board of Directors determines by a
         vote of a majority of the members of its entire Board of Directors,
         upon written notice to FNB at least 24 hours prior to the closing, if
         the Average Market Price of FNB Common Shares shall be less than
         $20.625; or

                 (h) By the Board of Directors of either FNB or West Coast
         (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(a) of this Agreement in
         the case of West Coast 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 West Coast, if at any time prior to the Effective Time,
         the fairness opinion of Advest, Inc. is withdrawn; or

                 (j) By West Coast 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 West Coast 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





                                       32
<PAGE>   38

         an investment banking firm of national reputation, is more favorable
         to the West Coast 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.  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 11.1 and Section 8.5 of this Agreement shall survive
any such termination and abandonment, and (ii) a termination pursuant to
Sections 10.1(b), 10.1(c), or 10.1(f) 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, (B) failure to obtain the requisite
approval of West Coast shareholders following a favorable recommendation by the
West Coast Board, or (C) the withdrawal by the West Coast financial advisor of
its fairness opinion), FNB shall be entitled to a cash payment from West Coast
in an amount equal to $500,000 upon the occurrence of any Subsequent Triggering
Event (as defined in the Stock Option Agreement) within twelve 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 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 West Coast for

                             STOCK OPTION AGREEMENT

         STOCK OPTION AGREEMENT, dated November 15, 1996, between F.N.B.
Corporation, a Pennsylvania corporation ("FNB") and West Coast Bancorp, Inc., a
Florida corporation ("West Coast").

                             W I T N E S S E T H :

         WHEREAS, FNB and West Coast 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, West Coast 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) West Coast hereby grants to FNB an irrevocable option (the
"Option") to purchase, subject to the terms hereof, up to 426,991 authorized
but unissued fully paid and nonassessable Common Shares, $1.00 par value, of
West Coast ("Common Shares"), at a price per Share equal to $15.00 (as adjusted
as set forth herein, the "Option Price"); provided, that in no event shall the
number of Shares for which this Option is exercisable, when combined with the
West Coast 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 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 West Coast 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 the Confidentiality Agreements (as defined in 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 (other than termination due to (A) the failure of FNB
to satisfy a condition to closing, (B) failure to obtain the requisite approval
of West Coast shareholders following a favorable recommendation by the West
Coast Board, or (C) the withdrawal by the West Coast financial advisor of its
fairness opinion);  (iii) the passage of 12 months (or such longer period as
provided in Section 10) after termination of the Merger Agreement if such
termination follows the occurrence of an Initial Triggering Event; or (iv) such
other date as to which the Holder and West Coast agree. The term "Holder" shall
mean the holder or holders of the Option. The rights set forth in Sections 7
and 9 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:
<PAGE>   2


                 (i) West Coast or any of its Subsidiaries (as hereinafter
         defined) (each a "West Coast Subsidiary"), 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 West Coast
         shall have recommended that the shareholders of West Coast 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 West Coast or any
         Significant Subsidiary (as defined in Rule 1- 02 of Regulation S-X
         promulgated by the Securities and Exchange Commission (the "SEC")) of
         West Coast, (y) a purchase, lease or other acquisition of all or
         substantially all of the assets or deposits of West Coast or any
         Significant Subsidiary of West Coast, 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 West Coast or any Significant Subsidiary of West Coast, 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 West
         Coast) other than FNB, any FNB Subsidiary or any West Coast 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 the West Coast 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 West
         Coast'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
         West Coast approve the transactions contemplated by the Merger
         Agreement, or West Coast or any West Coast Subsidiary, without having
         received FNB's prior written consent, shall have authorized,
         recommended, 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) Any person other than FNB or any FNB Subsidiary shall
         have made a bona fide proposal to West Coast or its shareholders to
         engage in an Acquisition Transaction, which proposal has an economic
         value equivalent to or in excess of that of FNB.

                 (v) West Coast 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





                                    - 2 -
<PAGE>   3



                 (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)  West Coast 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 West
Coast 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 West Coast 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 business days
nor later than 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 the West
Coast 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 (e) of this Section 2,
the Holder shall pay to West Coast 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 West Coast,
provided that failure or refusal of West Coast 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 (f) of this Section 2, West Coast
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 West Coast 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 West Coast 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 West Coast and will be provided to the
         holder hereof without charge upon receipt by West Coast of a written
         request therefor."

It is understood and agreed that: (1) 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 substitute certificate(s) without such reference if the
Holder shall have delivered to West Coast a copy of a letter from the staff of
the SEC, or an opinion of counsel, in form and substance satisfactory to West
Coast, 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 substitute certificate(s) without such 
reference if the shares have been sold or transferred in compliance with the 
provisions of this Agreement and under circumstances that do not require





                                    - 3 -
<PAGE>   4

the retention of such reference; and (iii) the legend shall be removed in its
entirety if the conditions in the proceeding 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 West Coast of the written notice
of exercise of the Option provided for under subsection (e) 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
West Coast shall then be closed or that certificates representing such Common
Shares shall not then be actually delivered to the Holder. West Coast 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. West Coast agrees: (i) 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;
(ii) 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
West Coast; (iii) promptly to take all action as may from time to time be
required (including (x) complying with all premerger notification, reporting
and waiting period requirements specified in 15 U.S.C. Section 18a and
regulations promulgated thereunder and (y) 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 West Coast duly and effectively to
issue Common Shares pursuant hereto; and (iv) 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 West Coast, 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 West Coast 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, West Coast 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 that 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 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




                                    - 4 -
<PAGE>   5

         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, West Coast 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. West Coast 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 West Coast's expense 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,
West Coast 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), West Coast will use its best efforts to effect the registration under
the 1933 Act of all Common Shares which West Coast 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.  West Coast shall be obligated to effect only one such piggy-back
registration pursuant to this Section 6.  FNB shall pay such incremental
expenses incurred by West Coast 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 West Coast 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, West
Coast 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 West Coast, 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 West Coast in the aggregate; and provided
further, however, that if such reduction occurs, then the West Coast 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 West
Coast for inclusion in any registration statement to be filed hereunder. If 
requested by any such Holder in connection with such registration, West Coast 
shall become a party to any underwriting agreement relating to the sale of 
such shares,





                                    - 5 -
<PAGE>   6

but only to the extent of obligating itself in respect of representations,
warranties, indemnities and other agreements customarily included in such
underwriting agreements for West Coast. In any such registration, West Coast
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, West Coast agrees to send a copy thereof to any
other person known to West Coast 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.

         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), West Coast 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), West Coast
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) 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 West Coast,
(iii) the highest closing price for Common Shares within the three-month period
immediately preceding the date the Holder gives notice of the required
repurchase of this Option or the Owner gives notice of the required repurchase
of Option Shares, as the case may be, or (iv) in the event of a sale of all or
substantially all of West Coast'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 West Coast 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 West Coast 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 West Coast to repurchase the Option and any Option Shares
pursuant to this Section 7 by surrendering for such purpose to West Coast, 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 West Coast 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 business days after the surrender of the Option and/or certificates
representing Option Shares and the receipt of such notice or notices relating
thereto, West Coast 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 West Coast is not then prohibited under
applicable law and regulation from so delivering.

         (c) To the extent that West Coast 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, West Coast 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 business days after the date on which West Coast is no longer so
prohibited; provided, however, that if West Coast at any time after delivery of
a notice of repurchase pursuant to paragraph (b) of this Section 7 is 
prohibited under





                                    - 6 -
<PAGE>   7

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 West Coast 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, West Coast 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 West Coast 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, West
Coast 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 West Coast and West
Coast 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 or any Significant Subsidiary's 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 (x) the
Acquiring Corporation (as hereinafter defined) or (y) 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 West Coast (if
    other than West Coast), (ii) West Coast in a merger in which West Coast is 
    the continuing or surviving person, and (iii) the transferee of all or 
    substantially all of West Coast's assets or deposits (or the assets or 
    deposits of a Significant Subsidiary of West Coast).

            (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 Share 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 West Coast is 
    the issuer of the Substitute Option, the Average Price shall be 
    computed with respect to common shares issued by the person merging 
    into West Coast 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





                                    - 7 -
<PAGE>   8

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 West Coast") 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 West Coast 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 West Coast to repurchase the Substitute Option and the Substitute Shares
pursuant to this Section 9 by surrendering for such purpose to the Substitute
Option West Coast, 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 West Coast 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 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 West Coast 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
West Coast is not then prohibited under applicable law and regulation from so
delivering.

         (c) To the extent that the Substitute Option West Coast is prohibited
under applicable law or regulation, or as a consequence of administrative
policy, from repurchasing the Substitute Option and/or the Substitute Shares in
part or in full, the Substitute Option West Coast 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 business days after the date on which
the Substitute Option West Coast is no longer so prohibited; provided, however,
that if the Substitute Option West Coast 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,





                                    - 8 -
<PAGE>   9

in full (and the Substitute Option West Coast 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 West Coast
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 West Coast
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 12 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. West Coast hereby represents and warrants to FNB as follows:

         (a) West Coast has full corporate power and authority to execute and
deliver this Agreement and 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 West Coast and no other corporate proceedings on the part
of West Coast are necessary to authorize this Agreement or to consummate the
transactions so contemplated. This Agreement has been duly and validly executed
and delivered by West Coast.

         (b) West Coast 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. 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 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.

         13. Each of FNB and West Coast 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, but FNB shall not be




                                    - 9 -

obligated to apply to state banking authorities for approval to acquire the 
Common Shares issuable hereunder until such time, if ever, as it deems 
appropriate to do so.

         14. 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.

         15. 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 West Coast 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 West Coast to allow the Holder to
acquire or to require West Coast to repurchase such lesser number of shares as
may be permissible, without any amendment or modification hereof.

         16. 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.

         17. 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.

         18. 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.

         19. 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.

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

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

FOR IMMEDIATE RELEASE:

                WEST COAST BANCORP, INC. AND F.N.B. CORPORATION
                                ANNOUNCE MERGER

CAPE CORAL, FL -- West Coast Bancorp, Inc. and F.N.B. Corporation today jointly
announced the signing of a definitive agreement to merge the two holding
companies.  Under the terms of the agreement, each share of West Coast Bancorp,
Inc. will be exchanged for .794 share of F.N.B. Corporation and the transaction
will be accounted for as a pooling of interests.  The actual per share value
will depend upon the price of F.N.B. stock at the closing of the transaction.
F.N.B. Corporation will issue 1.3 million shares in the tax free exchange,
making the total value of the transaction approximately $31 million.  The merger
is expected to close in the second quarter of 1997.

       West Coast Bancorp, Inc., a bank holding company headquartered in Cape
Coral, Florida, operates First National Bank of Southwest Florida in Lee County
with five banking locations.  At September 30, 1996, its assets totaled $155
million.

       F.N.B. Corporation is a bank holding company headquartered in Hermitage,
Pennsylvania, with $1.7 billion in assets.  It operates five banks and a 
consumer finance subsidiary through 94 offices in Pennsylvania, eastern Ohio and
southwest New York.  The

company recently announced record earnings for the first nine months of 1996 of
$15.4 million, $1.61 per share primary and $1.53 fully diluted, excluding the 
one time SAIF assessment mandated by Congress.  This represents a 17% increase
over the same period a year ago.

       Michael P. Geml, President and Chief Executive Officer of West Coast
Bancorp, Inc. enthusiastically remarked that "the transaction represents a
substantial premium over current market and book values.  F.N.B. provides
affiliates an operating environment which will ensure a continuation of our
commitment to superior customer service." Under the terms of the agreement,
First National Bank of Southwest Florida and Cape Coral National Bank will
merge their operations, resulting in the largest community bank in Cape Coral,
with more than 20% of the deposit market.  The Fort Myers offices of West Coast
will operate as a separate banking subsidiary, retaining the name First National
Bank of Southwest Florida.  "F.N.B. Corporation represents the caliber of
organization that West Coast Bancorp seeks to align itself, that being the
common goal of expanding its market presence," said Thomas R. Cronin, Chairman
of West Coast.  David W. Gomer will head up the Cape Coral operation, and Fort
Myers will be under the leadership of Michael Geml.  Geml concluded, "In
addition to realizing a premium on their stock ownership, shareholders will
benefit from higher dividends paid by F.N.B." F.N.B. Corporation's current
regular cash dividend on common stock is $.64 on an annual basis, which
represents a 2.7% yield.

       Earlier this year, F.N.B. Corporation announced an affiliation with
Southwest Banks, Inc., a bank holding company operating two banking
subsidiaries, First National Bank of Naples with five locations in Collier
County, and Cape Coral National Bank with two offices

<PAGE>   3

in Lee County.  All required approvals have been obtained for this transaction,
which is scheduled to close in January 1997.

       On a proforma consolidated basis, F.N.B. Corporation would have total
assets of $2.2 billion and total Shareholders' Equity of $200 million.

       Commenting on the proposed transaction, Peter Mortensen, Chairman and
President of F.N.B. Corporation, said, "The merger with West Coast provides an
opportunity to continue to employ our growing capital in this growth area."
Mortensen is one of the founders of Southwest Banks, Inc., as well as its lead
bank, First National Bank of Naples, and has served as a director of both
entities since their formation in 1988.  Mortensen added, "The transaction will
result in zero earnings dilution to our shareholders in the first year.  We view
this merger as an 'in-market' transaction and therefore will realize substantial
expense savings by combining the operations in Cape Coral.  We are committed to
retaining the best people of both organizations.  Considering the growth
potential and expansion plans, management's challenge is to reassign employees
into productive jobs."
