Item 5.  Other Events.

         As previously reported, on May 31, 1999, AmSouth Bancorporation, a
Delaware corporation ("AmSouth"), entered into an Agreement and Plan of Merger
(the "Merger Agreement") among AmSouth, First American Corporation, a Tennessee
corporation ("First American"), and Alpha/Foxtrot Acquisition Corp., a Delaware
corporation and wholly owned subsidiary of AmSouth (the "Merger Sub"), for a
tax-free merger of Merger Sub and First American, upon which each outstanding
share of common stock, par value $2.50 per share, of First American would be
converted into 1.871 shares of common stock, par value $1.00 per share, of
AmSouth (the "Proposed Merger").

         In connection with the Merger Agreement, AmSouth and First American
have also entered into cross stock option agreements, each dated June 1, 1999.
Pursuant to the First American stock option agreement (the "First American Stock
Option Agreement"), AmSouth granted to First American an irrevocable offer to
purchase, under certain circumstances, up to 35,025,240 shares of AmSouth common
stock at a price, subject to certain adjustments, of $ 28.5983 per share (the
"First American Option"). Pursuant to the AmSouth stock option agreement (the
"AmSouth Stock Option Agreement"), First American granted to AmSouth an
irrevocable offer to purchase, under certain circumstances, up to 23,250,165
shares of First American common stock at a price, subject to certain
adjustments, of $ 40.1625 per share (the "AmSouth Option", and, together with
the "First American Option", the "Options" ). Each of the Options, if exercised
by the grantee thereto, is intended to provide the grantee with the option to
purchase up to 19.9% of the total number of shares of the issuer then issued and
outstanding. Under certain circumstances, the issuer under each of the Options
may be required to repurchase the applicable Option or the shares acquired
pursuant to the exercise of such Option for a cash payment of at least $225
million. The Options may be exercised by the grantee thereto only if certain
events occur. These events can generally be described as business combinations
or acquisitions relating to the issuer of the particular Option (other than the
Proposed Merger).

         Attached and incorporated herein by reference in their entirety as
Exhibits 2.1, 10.1 and 10.2, respectively, are copies of (1) the Merger
Agreement, (2) the First American Stock Option Agreement and (3) the AmSouth
Stock Option Agreement.

                       CONSIDERATION; EXCHANGE PROCEDURES

      3.01 Effect on Capital Stock. As of the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any shares of First
American Stock or AmSouth Stock:

      (a) Conversion of First American Common Stock. Except as set forth in this
   Section 3.01(a), each share of First American Common Stock outstanding
   immediately prior to the Effective Time shall be converted into 1.871 (the
   "Exchange Ratio") fully paid and nonassessable shares of AmSouth Common
   Stock. As of the Effective Time, all shares of First American Common Stock
   shall no longer be outstanding and shall automatically be canceled and shall
   cease to exist, and from and after the Effective Time, certificates
   representing First American Common Stock immediately prior to the Effective
   Time shall be deemed for all purposes to represent the number of shares of
   AmSouth Common Stock into which they were converted pursuant to this Section
   3.01(a).

      (b) AmSouth Common Stock. Each share of AmSouth Stock issued and
   outstanding immediately prior to the Effective Time shall remain issued and
   outstanding.



                                      -10-



<PAGE>



      (c) Conversion of Merger Sub Stock. The shares of stock of any class or
   series of Merger Sub Stock (the "Merger Sub Stock") issued and outstanding
   immediately prior to the Effective Time shall become shares of stock of the
   Surviving Corporation at the Effective Time having the same terms, rights and
   preferences.

      3.02 Rights as Stockholders; Stock Transfers. At the Effective Time,
holders of First American Common Stock shall cease to be, and shall have no
rights as, shareholders of First American, other than to receive any dividend or
other distribution with respect to such First American Common Stock with a
record date occurring prior to the Effective Date and the conversion rights
provided under this Article III. After the Effective Time, there shall be no
transfers on the stock transfer books of AmSouth or the Surviving Corporation of
shares of First American Common Stock.

      3.03 Exchange Procedures. (a) At or prior to the Effective Time, AmSouth
shall deposit, or shall cause to be deposited, with AmSouth's transfer agent or
a depository or trust institution of recognized standing selected by First
American and reasonably satisfactory to AmSouth (in such capacity, the "Exchange
Agent"), for the benefit of the holders of certificates formerly representing
shares of First American Common Stock ("Old Certificates") to be exchanged in
accordance with this Article III, certificates representing the shares of
AmSouth Common Stock ("New Certificates") to which the holders of the Old
Certificates are entitled pursuant to this Agreement.

      (b) Promptly after the Effective Date, AmSouth shall send or cause to be
sent to each former holder of record of shares of First American Common Stock
immediately prior to the Effective Time transmittal materials for use in
exchanging such shareholder's Old Certificates for the New Certificates provided
for in this Article III. AmSouth shall cause the New Certificates and/or any
check in respect of dividends or distributions which such Person shall be
entitled to receive to be delivered to such shareholder upon delivery to the
Exchange Agent of Old Certificates representing such shares of AmSouth Common
Stock (or indemnity reasonably satisfactory to AmSouth and the Exchange Agent,
if any of such certificates are lost, stolen or destroyed) owned by such
shareholder. No interest will be paid on any such cash to be paid in respect of
dividends or distributions which any such Person shall be entitled to receive
pursuant to this Article III upon such delivery.

      (c) Neither the Exchange Agent nor any party hereto shall be liable to any
former holder of First American Common Stock for any amount properly delivered
to a public official pursuant to applicable abandoned property, escheat or
similar laws.

      (d) From and after the 30th day following the Effective Date, no dividends
or other distributions with respect to AmSouth Common Stock with a record date
occurring after the Effective Date shall be paid in respect of any unsurrendered
Old Certificate representing shares of AmSouth Common Stock converted in the
Merger into the right to receive shares of AmSouth Common Stock. Upon surrender
of Old Certificates (or indemnity reasonably satisfactory to AmSouth and the
Exchange Agent, if any of such certificates are lost, stolen or destroyed) in
accordance with this


                                      -11-



<PAGE>



Section 3.03, the record holder thereof shall be entitled to receive any such
dividends or other distributions, without any interest thereon, which
theretofore had become payable with respect to shares of AmSouth Common Stock
such holder had the right to receive upon surrender of Old Certificates (or
delivery of such indemnity).

      (e) Notwithstanding any other provision hereof, no fractional shares of
AmSouth Common Stock and no certificates or scrip therefor, or other evidence of
ownership thereof, will be issued in the Merger; instead, AmSouth shall pay to
each holder of First American Common Stock who would otherwise be entitled to a
fractional share of AmSouth Common Stock (after taking into account all Old
Certificates delivered by such holder) an amount in cash (without interest)
determined by multiplying such fraction by the average of the last reported sale
prices of AmSouth Common Stock, as reported by the NYSE Composite Transactions
Reporting System (as reported in The Wall Street Journal or, if not reported
therein, in another authoritative source), for the five NYSE trading days
immediately preceding the Effective Date.

      3.04 Anti-Dilution Provisions. If AmSouth changes (or establishes a record
date for changing) the number or kind of shares of AmSouth Common Stock issued
and outstanding prior to the Effective Date as a result of a stock split, stock
dividend, recapitalization, reclassification, reorganization or similar
transaction with respect to the outstanding AmSouth Common Stock and the record
date therefor shall be prior to the Effective Date, the Exchange Ratio shall be
proportionately adjusted.

      3.05 Stock Options. At the Effective Time, all employee and director stock
options to purchase shares of First American Common Stock (each, a "First
American Stock Option"), which are then outstanding and unexercised, shall cease
to represent a right to acquire shares of First American Common Stock and shall
be converted automatically into options to purchase shares of AmSouth Common
Stock, (each, an "AmSouth Stock Option") and AmSouth shall assume each such
First American Stock Option subject to the terms thereof, including but not
limited to the accelerated vesting of such options which shall occur in
connection with and by virtue of the transactions contemplated hereby as and to
the extent required by the plans and agreements governing such First American
Stock Options; provided, however, that from and after the Effective Time, (1)
the number of shares of AmSouth Common Stock purchasable upon exercise of such
First American Stock Option shall be equal to the number of shares of First
American Common Stock that were purchasable under such First American Stock
Option immediately prior to the Effective Time multiplied by the Exchange Ratio,
and rounding to the nearest whole share, and (2) the per share exercise price
under each such First American Stock Option shall be adjusted by dividing the
per share exercise price of each such First American Stock Option by the
Exchange Ratio, and rounding down to the nearest cent. The terms of each First
American Stock Option shall, in accordance with its terms, be subject to further
adjustment as appropriate to reflect any stock split, stock dividend,
recapitalization or other similar transactions with respect to AmSouth Common
Stock on or subsequent to the Effective Date. Notwithstanding the foregoing,
each First American Stock Option which is intended to be an "incentive stock
option" (as defined


                                      -12-



<PAGE>



in Section 422 of the Code) shall be adjusted in accordance with the
requirements of Section 424 of the Code. Accordingly, with respect to any
incentive stock options, fractional shares shall be rounded down to the nearest
whole number of shares and where necessary the per share exercise price shall be
rounded down to the nearest cent. At or prior to the Effective Time, AmSouth
shall take all corporate action necessary to reserve for issuance a sufficient
number of shares of AmSouth Common Stock for delivery upon exercise of First
American Stock Options assumed by it in accordance with this Section 3.05. As
soon as practicable after the Effective Time, AmSouth 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 AmSouth Common Stock subject to First
American Stock Options converted hereunder.

   Merger Sub is a corporation duly organized, validly existing and in good
   standing under the laws of the State of Delaware, and all of its outstanding
   capital stock is owned directly or indirectly by AmSouth. Merger Sub was

   applicability relating to or affecting creditors' rights or by general equity

   capital stock necessary to approve and adopt this Agreement, the Option
   Agreements and the transactions contemplated hereby and thereby.

      (3) In the case of First American, the affirmative vote of the holders of

   preceding paragraph, and the expiration of related waiting periods, and
   required filings under federal and state securities laws, the execution,
   delivery and performance of this Agreement and the consummation of the
   transactions contemplated hereby do not and will not (A) constitute a breach
   or violation of, or a default under, or give rise to any Lien, any
   acceleration of remedies or any right of termination under, any law, rule or
   regulation or any judgment, decree, order, governmental permit or license, or
   agreement, indenture or instrument of it or of any of its Subsidiaries or to
   which it or any of its Subsidiaries or properties is subject or bound, (B)
   constitute a breach or violation of, or a default under, its Constituent

<PAGE>



   requirements under the Securities Act or the Exchange Act, as the case may
   be, and (B) did not 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 therein, in the light of the circumstances under which they
   were made, not misleading; and each of the balance sheets contained in or
   incorporated by reference into any such Regulatory Filing (including the
   related notes and schedules thereto) fairly presented in all material
   respects its financial position and that of its Subsidiaries as of its date,
   and each of the statements of income and changes in shareholders' equity and
   cash flows or equivalent statements in such Regulatory Filings (including any
   related notes and schedules thereto) fairly presented in all material
   respects, the results of operations, changes in shareholders' equity and
   changes in cash flows, as the case may be, of it and its Subsidiaries for the
   periods to which they relate, in each case in accordance with GAAP
   consistently applied during the periods involved, except in each case as may
   be noted therein, subject to normal year-end audit adjustments in the case of
   unaudited statements.

      (2) Since December 31, 1998, it and its Subsidiaries have not incurred any
   liability other than in the ordinary course of business consistent with past
   practice.

      (3) Since December 31, 1998, (A) it and its Subsidiaries have conducted
   their respective businesses in the ordinary and usual course consistent with
   past practice (excluding the incurrence of expenses related to this Agreement
   and the transactions contemplated hereby) and (B) no event has occurred or
   circumstance arisen that, individually or taken together with all other
   facts, circumstances and events (described in any paragraph of Section 5.03
   or otherwise), is reasonably likely to have a Material Adverse Effect with
   respect to it.

      (i) Litigation. Except as Previously Disclosed or set forth in its Annual
   Report on Form 10-K for the fiscal year ended December 31, 1998, there is no
   suit, action or proceeding pending or, to the knowledge of it, threatened
   against or affecting it or any of its Subsidiaries (and it is not aware of
   any basis for any such suit, action or proceeding) that, individually or in
   the aggregate, is (1) material to it and its Subsidiaries, taken as a whole,
   or (2) that is reasonably likely to prevent or delay it in any material
   respect from performing its obligations under, or consummating the
   transactions contemplated by, this Agreement.

      (j) Regulatory Matters. (1) Neither it nor any of its Subsidiaries is a
   party to or is subject to any written order, decree, agreement, memorandum of

   institutions or issuers of securities or engaged in the insurance of deposits
   or the supervision or regulation of it or any of its Subsidiaries
   (collectively, the "Regulatory Authorities").



                                      -20-



<PAGE>



      (2) Neither it nor any of its Subsidiaries has been advised by any
   Regulatory Authority that such Regulatory Authority is contemplating issuing
   or requesting (or is considering the appropriateness of issuing or
   requesting) any such written order, decree, agreement, memorandum of
   understanding, commitment letter, supervisory letter or similar submission.

      (k) Compliance with Laws. It and each of its Subsidiaries:

      (i) conducts its business in compliance with all applicable federal,
   state, local and foreign statutes, laws, regulations, ordinances, rules,
   judgments, orders or decrees applicable thereto or to the employees
   conducting such businesses, including, without limitation, the Equal Credit
   Opportunity Act, the Fair Housing Act, the Community Reinvestment Act, the
   Home Mortgage Disclosure Act and all other applicable fair lending laws and
   other laws relating to discriminatory business practices;

      (ii) has all permits, licenses, authorizations, orders and approvals of,
   and has made all filings, applications and registrations with, all
   Governmental Authorities that are required in order to permit them to own or
   lease their properties and to conduct their businesses as presently
   conducted; all such permits, licenses, certificates of authority, orders and
   approvals are in full force and effect and, to its knowledge, no suspension
   or cancellation of any of them is threatened; and

      (iii) has received, since December 31, 1998, no written notification from
   any Governmental Authority (A) asserting that it or any of its Subsidiaries

   which such Governmental Authority enforces or (B) threatening to revoke any
   license, franchise, permit or governmental authorization.

      (l) Material Contracts; Defaults. Except for those agreements and other
   documents filed as exhibits to its Regulatory Filings, neither it nor any of
   its Subsidiaries is a party to, bound by or subject to any agreement,
   contract, arrangement, commitment or understanding (whether written or oral)
   (i) that is a "material contract" within the meaning of Item 601(b)(10) of
   the SEC's Regulation S-K or (ii) that restricts the conduct of business by it
   or any of its Subsidiaries. Neither it nor any of its Subsidiaries is in
   default under any material contract, agreement, commitment, arrangement,
   lease, insurance policy or other instrument to which it is a party, by which
   its respective assets, business, or operations may be bound or affected, or
   under which it or its respective assets, business, or operations receives
   benefits, and there has not occurred any event that, with the lapse of time
   or the giving of notice or both, would constitute such a default.

      (m) No Brokers. No action has been taken by it that would give rise to any
   valid claim against any party hereto for a brokerage commission, finder's fee
   or other like payment with respect to the transactions contemplated by this
   Agreement, excluding a Previously Disclosed fee to be paid to Donaldson,
   Lufkin & Jenrette Securities Corporation, in the case of AmSouth, and a
   Previously Disclosed fee to


                                      -21-

   be paid to Merrill Lynch, Pierce, Fenner and Smith Incorporated, in the case
   of First American.

      (n)  Employee Benefit Plans.

      (1) All material benefit and compensation plans, contracts, policies or
   arrangements covering its current employees or former employees and those of
   its Subsidiaries (its "Employees") and its current or former directors,
   including, but not limited to, "employee benefit plans" within the meaning of
   Section 3(3) of ERISA, and deferred compensation, stock option, stock
   purchase, stock appreciation rights, stock based, incentive and bonus plans
   (its "Benefit Plans"), are Previously Disclosed. True and complete copies of
   all Benefit Plans, including, but not limited to, any trust instruments and
   insurance contracts forming a part of any Benefit Plans, and all amendments
   thereto, have been made available to the other party hereto.

      (2) All employee benefit plans, other than "multiemployer plans" within
   the meaning of Section 3(37) of ERISA, covering its Employees (its "Plans"),
   to the extent subject to ERISA, are in substantial compliance with ERISA.
   Each of its Plans which is an "employee pension benefit plan" within the
   meaning of Section 3(2) of ERISA ("Pension Plan"), and which is intended to
   be qualified under Section 401(a) of the Code has received a favorable
   determination letter from the Internal Revenue Service with respect to "TRA"
   (as defined in Section 1 of Rev. Proc. 93-39), and it is not aware of any
   circumstances reasonably likely to result in revocation of any such favorable
   determination letter. There is no material pending or, to the knowledge of
   First American or AmSouth, as the case may be, threatened litigation relating
   to its Plans. Neither it nor any of its Subsidiaries has engaged in a
   transaction with respect to any of its Plans that, assuming the taxable
   period of such transaction expired as of the date hereof, could subject it or
   any of its Subsidiaries to a tax or penalty imposed by either Section 4975 of
   the Code or Section 502(i) of ERISA in an amount which would be material.

      (3) No liability under Subtitle C or D of Title IV of ERISA has been or is
   reasonably expected to be incurred by it or any of its Subsidiaries with
   respect to any ongoing, frozen or terminated "single-employer plan", within
   the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained
   by any of them, or the single-employer plan of any entity which is considered
   one employer with it under Section 4001 of ERISA or Section 414 of the Code
   (an "ERISA Affiliate"). None of it, any of its Subsidiaries or any of its
   ERISA Affiliates has contributed to a "multiemployer plan", within the
   meaning of Section 3(37) of ERISA, at any time on or after September 26,
   1980. No notice of a "reportable event", within the meaning of Section 4043
   of ERISA for which the 30-day reporting requirement has not been waived, has
   been required to be filed for any of its Pension Plans or by any of its ERISA
   Affiliates within the 12-month period ending on the date hereof or will be
   required to be filed solely as a result of the transactions contemplated by
   this Agreement.



                                      -22-



<PAGE>



      (4) All contributions required to be made under the terms of any of its
   Plans have been timely made or have been reflected on its consolidated
   financial statements included in its Regulatory Filings. None of its Pension
   Plans or any single-employer plan of any of its ERISA Affiliates has an
   "accumulated funding deficiency" (whether or not waived) within the meaning
   of Section 412 of the Code or Section 302 of ERISA and none of its ERISA
   Affiliates has an outstanding funding waiver. Neither it nor any of its
   Subsidiaries has provided, or is required to provide, security to any of its
   Pension Plans or to any single-employer plan of any of its ERISA Affiliates
   pursuant to Section 401(a)(29) of the Code.

      (5) Under each of its Pension Plans which is a single-employer plan, as of
   the last day of the most recent plan year ended prior to the date hereof, the
   actuarially determined present value of all "benefit liabilities", within the
   meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the
   actuarial assumptions contained in its Plan's most recent actuarial
   valuation), did not exceed the then current value of the assets of such Plan,
   and there has been no material change in the financial condition of such Plan
   since the last day of the most recent plan year.

      (6) Neither it nor any of its Subsidiaries has any obligations for retiree
   health and life benefits under any of its Benefit Plans. It or its
   Subsidiaries may amend or terminate any of its Benefit Plans at any time
   without incurring any liability thereunder.

      (7) Neither its execution of this Agreement, the performance of its
   obligations hereunder, the consummation of the transactions contemplated by
   this Agreement, the termination of the employment of any of its employees
   within a specified time of the Effective Time, nor any other action taken or
   failed to be taken by it prior to the execution of this Agreement will (w)
   limit its right, in its sole discretion, to administer or amend in any
   respect or terminate any of its Benefit Plans or any related trust, (x)
   entitle any of its employees or any employees of its Subsidiaries to
   severance pay, (y) accelerate the time of payment or vesting or trigger any
   payment of compensation or benefits under, increase the amount payable or
   trigger any other material obligation pursuant to, any of its Benefit Plans
   or (z) result in any breach or violation of, or a default under, any of its
   Benefit Plans. Without limiting the foregoing, as a result of the
   consummation of the transactions contemplated by this Agreement (including,
   without limitation, as a result of the termination of the employment of any
   of its employees within a specified time of the Effective Time) neither it
   nor any of its Subsidiaries will be obligated to make a payment to an
   individual that would be a "parachute payment" to a "disqualified individual"
   as those terms are defined in Section 280G of the Code, without regard to
   whether such payment is reasonable compensation for personal services
   performed or to be performed in the future.

      (o) Labor Matters. Neither it nor any of its Subsidiaries is a party to or
   is bound by any collective bargaining agreement, contract or other agreement
   or understanding with a labor union or labor organization, nor is it or any
   of its Subsidiaries the subject of a proceeding asserting that it or any such
   Subsidiary


                                      -23-



<PAGE>



   has committed an unfair labor practice (within the meaning of the National
   Labor Relations Act) or seeking to compel it or any of its Subsidiaries to
   bargain with any labor organization as to wages or conditions of employment,
   nor is there any strike or other material labor dispute involving it or any
   of its Subsidiaries pending or, to its knowledge, threatened, nor to its
   knowledge is there any activity involving its or any of its Subsidiaries'
   employees seeking to certify a collective bargaining unit or engaging in
   other organizational activity.

      (p) Environmental Matters. To its knowledge, neither its conduct nor its
   operation or the conduct or operation of its Subsidiaries nor any condition
   of any property presently or previously owned, leased or operated by any of
   them (including, without limitation, in a fiduciary or agency capacity),
   violates or violated Environmental Laws and no condition has existed or event
   has occurred with respect to any of them or any such property that, with
   notice or the passage of time, or both, is reasonably likely to result in
   liability under Environmental Laws. To its knowledge, no property on which it
   or any of its Subsidiaries holds a Lien, violates or violated Environmental
   Laws and no condition has existed or event has occurred with respect to any
   such property that, with notice or the passage of time, or both, is
   reasonably likely to result in liability under Environmental Laws. Neither it
   nor any of its Subsidiaries has received any written notice from any person
   or entity that it or its Subsidiaries or the operation or condition of any
   property ever owned, leased, operated, or held as collateral or in a
   fiduciary capacity by any of them are or were in violation of or otherwise
   are alleged to have liability under any Environmental Law, including, but not
   limited to, responsibility (or potential responsibility) for the cleanup or
   other remediation of any pollutants, contaminants, or hazardous or toxic
   wastes, substances or materials at, on, beneath, or originating from, any
   such property.

      (q) Tax Matters. (1) (A) All Tax Returns that are required to be filed
   (taking into account any extensions of time within which to file) by or with
   respect to it and its Subsidiaries have been duly and timely filed, and all
   such Tax Returns are complete and accurate in all material respects, (B) all
   Taxes shown to be due on the Tax Returns referred to in clause (A) have been
   paid in full, (C) all Taxes that it or any of its Subsidiaries is obligated
   to withhold from amounts owing to any employee, creditor or third party have
   been paid over to the proper Governmental Authority in a timely manner, to
   the extent due and payable, (D) the Tax Returns referred to in clause (A)
   have been examined by the Internal Revenue Service or the appropriate Tax
   authority or the period for assessment of the Taxes in respect of which such
   Tax Returns were required to be filed has expired, (E) all deficiencies
   asserted or assessments made as a result of such examinations have been paid
   in full, (F) no issues that have been raised by the relevant taxing authority
   in connection with the examination of any of the Tax Returns referred to in
   clause (A) are currently pending, and (G) no extensions or waivers of
   statutes of limitation have been given by or requested with respect to any of
   its Taxes or those of its Subsidiaries. It has made available to the other
   party hereto true and correct copies of the U.S. federal income Tax Returns
   filed by it and its Subsidiaries for each of the three most recent fiscal
   years ended on or before December 31, 1998.


                                      -24-

   It has made provision in accordance with GAAP, in the financial statements
   included in the Regulatory Filings filed prior to the date hereof, for all
   Taxes that accrued on or before the end of the most recent period covered by
   its Regulatory Filings filed prior to the date hereof. Neither it nor any of
   its Subsidiaries is a party to any Tax allocation or sharing agreement, is or
   has been a member of an affiliated group filing consolidated or combined Tax
   returns (other than a group over which it is or was the common parent) or
   otherwise has any liability for the Taxes of any person (other than its own
   Taxes and those of its Subsidiaries). As of the date hereof, neither it nor
   any of its Subsidiaries has any reason to believe that any conditions exist
   that could reasonably be expected to prevent or impede the Merger from
   qualifying as a reorganization within the meaning of Section 368(a) of the
   Code. No Liens for Taxes exist with respect to any of its assets or
   properties or those of its Subsidiaries, except for statutory Liens for Taxes
   not yet due and payable or that are being contested in good faith and
   reserved for in accordance with GAAP. Neither it nor any of its Subsidiaries
   has been a party to any distribution occurring during the last three years in
   which the parties to such distribution treated the distribution as one to
   which Section 355 of the Code applied.

      (2) No Tax is required to be withheld pursuant to Section 1445 of the Code
   as a result of the transfer contemplated by this Agreement.

      (r) Derivative Instruments. All interest rate swaps, caps, floors, option
   agreements, futures and forward contracts and other similar risk management
   arrangements, whether entered into for its own account, or for the account of
   one or more of its Subsidiaries or their customers, if any, were entered into
   (1) in accordance with prudent business practices and all applicable laws,
   rules, regulations and regulatory policies and (2) with counterparties
   believed to be financially responsible at the time; and each of them
   constitutes the valid and legally binding obligation of such party or one of
   its Subsidiaries, enforceable in accordance with its terms (except as
   enforceability may be limited by applicable bankruptcy, insolvency,
   reorganization, moratorium, fraudulent transfer and similar laws of general
   applicability relating to or affecting creditors' rights or by general equity
   principles), and are in full force and effect. Neither it nor its
   Subsidiaries, nor to its knowledge, any other party thereto, is in breach of

   insurance policies, binders, or bonds maintained by it or its Subsidiaries
   (its "Insurance Policies"). It and its Subsidiaries are insured with
   reputable insurers against such risks and in such amounts as its management
   reasonably has determined to be prudent in accordance with industry
   practices. All of its


                                      -25-

   Insurance Policies are in full force and effect; it and its Subsidiaries are
   not in material default thereunder; and all claims thereunder for which a
   basis is known, or reasonably should be known, by it have been filed in due
   and timely fashion.

      (u) Accounting Treatment. As of the date hereof, to its knowledge, there
   is no reason why the Merger will fail to qualify for "pooling-of-interests"
   accounting treatment.

      (v) Takeover Laws and Provisions. It has taken all action required to be
   taken by it in order to exempt this Agreement and the AmSouth Option or the
   First American Option, as applicable, and the transactions contemplated
   hereby and thereby from, and this Agreement, the AmSouth Option or the First
   American Option, as applicable, and the transactions contemplated hereby and
   thereby are exempt from, the requirements of any "moratorium", "control
   share", "fair price", "affiliate transaction", "business combination" or
   other antitakeover laws and regulations of any state (collectively, "Takeover
   Laws"), including, without limitation, the State of Delaware, in the case of
   AmSouth, and the State of Tennessee, in the case of First American. It has
   taken all action required to be taken by it in order to make this Agreement
   and the AmSouth Option or the First American Option, as applicable, and the

   the AmSouth Option or the First American Option, as applicable, and the
   transactions contemplated hereby and thereby comply with, the requirements of
   any Articles, Sections or provisions of its Constituent Documents concerning

   requirements" or other related provisions (collectively, "Takeover
   Provisions"), including, without limitation, Articles X, XI and XII of the
   First American Charter, in the case of First American, and Section VIII of
   the AmSouth Certificate, in the case of AmSouth.

      (w) Rights Agreements. It has taken all action necessary such that (1) the
   AmSouth Rights or the First American Rights, as the case may be, will not
   become separable, distributable, unredeemable or exercisable as a result of
   the approval, execution or delivery of this Agreement or the Option
   Agreements or the consummation of the transactions contemplated hereby or
   thereby and (2) in the case of First American, the First American Rights will
   no longer be exercisable, and the First American Rights Agreement will
   terminate, upon consummation of the Merger.

      (x) Year 2000. To its knowledge, the mission critical computer software
   operated by it and/or any of its Subsidiaries is currently capable of
   providing, or is being adapted to provide, uninterrupted millennium
   functionality to record, store, process and present calendar dates falling on
   or after January 1, 2000 in substantially the same manner and with
   substantially the same functionality as such mission critical software
   records, stores, processes and presents such calendar dates falling on or
   before December 31, 1999. To its knowledge, the costs of adaptations referred
   to in this clause will not have a Material Adverse Effect with respect to it.
   Neither it nor any of its Subsidiaries has received, nor to its

   knowledge are there facts that would reasonably be expected to form the basis
   for the issuance of, a "Year 2000 Deficiency Notification Letter" (as such
   term is employed in the Federal Reserve's Supervision and Regulatory Letter
   No. SR 98-3 (SUP), dated March 4, 1998) or similar notice from any state
   banking authority. It has made available to the other party hereto a complete
   and accurate copy of its and its Subsidiaries' plan, including an estimate of
   anticipated associated costs, for addressing the issues set forth in the Year
   2000 guidance papers issued by the Federal Financial Institutions Examination
   Council, including the statements dated May 5, 1997, entitled "Year 2000
   Project Management Awareness," December 17, 1997, entitled "Safety and
   Soundness Guidelines Concerning the Year 2000 Business Risk," and October 14,
   1998, entitled "Interagency Guidelines Establishing Year 2000 Standards for
   Safety and Soundness," as such issues affect any of it or its Subsidiaries.
   Between the date of this Agreement and the Effective Time, it shall use
   commercially reasonable and practicable efforts to implement such plan.

party hereto to that end.

      6.02 Stockholder Approvals. (a) Each of AmSouth and First American agrees
to take in accordance with applicable law and its respective Constituent
Documents all action necessary to convene a meeting of its respective
stockholders (including any adjournment or postponement, the "AmSouth Meeting"
and the "First American Meeting", respectively), as promptly as practicable, to
consider and vote upon the Share Increase and the adoption and approval of this
Agreement, respectively, as well as any other matters required to be approved by

      (b) The board of directors of First American has adopted resolutions
recommending to the stockholders of First American adoption of this Agreement

approval of the Share Increase. Such boards of directors shall at all times
continue such recommendations in effect without qualification and shall use, and
cause AmSouth and First American, respectively, to use reasonable best efforts
to obtain such adoption (it being understood and agreed that the obligations
under this


                                      -27-

sentence shall not be altered by the commencement, proposal, disclosure or

materials of AmSouth and First American constituting a part thereof (the "Joint

and to cause their Subsidiaries to cooperate, with the other party, its counsel
and its accountants, in the preparation of the Registration Statement and the
Joint Proxy Statement; and provided that both parties and their respective
Subsidiaries have cooperated as required above, AmSouth and First American agree
to file the Joint Proxy Statement in preliminary form with the SEC as promptly
as reasonably practicable, and AmSouth agrees to file the Registration Statement
with the SEC as soon as reasonably practicable after any SEC comments with

stockholders as may be reasonably requested in connection with the foregoing.

      (b) Each of AmSouth and First American agrees, as to itself and its
Subsidiaries, that none of the information supplied or to be supplied by it for

at the time the Registration Statement and each amendment or supplement thereto,
if any, becomes effective under the Securities Act, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not misleading and (2) the
Joint Proxy Statement and any amendment or supplement thereto will, at the date
of mailing to stockholders and at the time of the AmSouth Meeting or the First
American Meeting, as the case may be, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which such statement was made, not misleading. Each of AmSouth and First
American further agrees that if it shall become aware prior to the Effective
Date of any information furnished by it that would cause any of the statements
in the Joint Proxy Statement or the Registration Statement to be false or
misleading with respect to any material fact, or to omit to state any material
fact necessary to make the statements therein not false or misleading, to
promptly inform the other party thereof and to take the necessary steps to
correct the Joint Proxy Statement or the Registration Statement.

statement as may upon the advice of outside counsel be required by law or the
rules and regulations of the NYSE. AmSouth and First American shall cooperate to

it shall furnish promptly to such other party (1) a copy of each material
report, schedule and other document filed by it pursuant to the requirements of
federal or state securities or banking laws, and (2) all other information

data as to the other party to be returned to the other party.

concerning, or provide any confidential information to, or have any discussions
with, any Person relating to, any Acquisition Proposal or waive any provision of
or amend the terms of the AmSouth Rights Agreement or the First American Rights

and First American shall immediately cease and cause to be terminated any

24 hours) advise the other party following the receipt by AmSouth or First
American, as the case may be, of any Acquisition Proposal and the substance
thereof (including the identity of the person making such Acquisition Proposal),
and shall keep such other party apprised of any developments in respect thereof
on a current basis.

Effective Time) (as opposed to First American or such Subsidiary) with respect
to claims against such directors and officers arising from facts or events
occurring at or prior to the Effective Time (including, without limitation, the
transactions contemplated by this Agreement) which insurance shall contain at
least the same coverage and amounts, and contain terms and conditions no less

honored, in accordance with their terms, all vested or accrued benefit
obligations to, and contractual rights of, current and former employees of First

any event prior to the Effective Time adopt a resolution providing that the

                            STOCK OPTION AGREEMENT

    STOCK OPTION AGREEMENT, dated as of June 1, 1999 (this "Agreement"), between
First American Corporation, a Tennessee corporation ("Grantee"), and AmSouth
Bancorporation, a Delaware corporation ("Issuer").

                                   RECITALS

        A. Merger Agreement. Grantee and Issuer have entered into an Agreement
and Plan of Merger, dated as of May 31, 1999 (the "Merger Agreement"), which
agreement was executed and delivered on the day preceding the date of this Stock
Option Agreement; and

        B. Option. As a condition to Grantee's entering into the Merger
Agreement and in consideration therefor, Issuer has agreed to grant Grantee 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) Issuer hereby grants to Grantee an unconditional, irrevocable option
(the "Option") to purchase, subject to the terms hereof, up to an aggregate of
35,025,240 fully paid and nonassessable shares of the common stock, par value
$1.00 per share, of Issuer ("Common Stock") at a price per share equal to
$28.5983; provided, however, that in no event shall the number of shares for
which this Option is exercisable exceed 19.9% of the issued and outstanding
shares of Common Stock. The number of shares of Common Stock 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 shares of Common Stock are issued or
otherwise become outstanding after the date of this Agreement (other than
pursuant to this Agreement and other than pursuant to an event described in
Section 5(a) hereof), the number of shares of Common Stock subject to the Option
shall be increased so that, after such issuance, such number together with any
shares of Common Stock previously issued pursuant hereto, equals 19.9% of the
number of shares of Common Stock then issued and outstanding without giving
effect to any shares subject or issued pursuant to the Option. Nothing contained
in this Section l(b) or elsewhere in this Agreement shall be deemed to authorize
Issuer to issue shares in breach of any provision of the Merger Agreement.

    2. (a) The Holder (as hereinafter defined) may exercise the Option, 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), provided that the Holder shall have sent the written
notice of such exercise (as provided in subsection (e) of





<PAGE>



this Section 2) within six (6) months following such Subsequent Triggering Event
(or such later period as provided in Section 10). Each of the following shall be
an Exercise Termination Event: (i) the Effective Time 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
except a termination by Grantee pursuant to Section 8.01(b) of the Merger
Agreement (unless the breach by Issuer giving rise to such right of termination
is non-volitional) (a "Listed Termination"); or (iii) the passage of eighteen
(18) 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 is a Listed Termination. The term "Holder" shall mean the
holder or holders of the Option. Notwithstanding anything to the contrary
contained herein, the Option may not be exercised at any time when Grantee shall
be in material breach of any of its covenants or agreements contained in the
Merger Agreement such that Issuer shall be entitled to terminate the Merger
Agreement pursuant to Section 8.01(b) thereof.

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

       (i) Issuer or any of its Significant Subsidiaries (as defined in Rule
    1-02 of Regulation S-X promulgated by the Securities and Exchange Commission
    (the "SEC")) (the "Issuer Subsidiaries"), without having received Grantee'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, as
    amended (the "1934 Act"), and the rules and regulations thereunder) other
    than Grantee or any of its Subsidiaries (each a "Grantee Subsidiary") or the
    Board of Directors of Issuer (the "Issuer Board") shall have recommended
    that the stockholders of Issuer approve or accept any Acquisition
    Transaction other than as contemplated by the Merger Agreement. For purposes
    of this Agreement, (a) "Acquisition Transaction" shall mean (x) a merger or
    consolidation, or any similar transaction, involving Issuer or any Issuer
    Subsidiary (other than mergers, consolidations or similar transactions
    involving solely Issuer and/or one or more wholly-owned Subsidiaries of the
    Issuer, provided, any such transaction is not entered into in violation of
    the terms of the Merger Agreement), (y) a purchase, lease or other
    acquisition of all or any substantial part of the assets or deposits of
    Issuer or any Issuer Subsidiary, or (z) a purchase or other acquisition
    (including by way of merger, consolidation, share exchange or otherwise) of
    securities representing 10% or more of the voting power of Issuer or any
    Issuer Subsidiary and (b) "Subsidiary" shall have the meaning set forth in
    Rule 12b-2 under the 1934 Act;

      (ii) Any person other than the Grantee or any Grantee Subsidiary shall
    have acquired beneficial ownership or the right to acquire beneficial
    ownership of 10% or more of the outstanding shares of Common Stock (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);


                                       -2-



<PAGE>



     (iii) The stockholders of Issuer shall have voted and failed to approve the
    Merger Agreement and the Merger at a meeting which has been held for that
    purpose or any adjournment or postponement thereof, or such meeting shall
    not have been held in violation of the Merger Agreement or shall have been
    canceled prior to termination of the Merger Agreement if, prior to such
    meeting (or if such meeting shall not have been held or shall have been
    canceled, prior to such termination), it shall have been publicly announced
    that any person (other than Grantee or any of its Subsidiaries) shall have
    made, or disclosed an intention to make, a proposal to engage in an
    Acquisition Transaction;

      (iv) The Issuer Board shall have withdrawn, modified or qualified (or
    publicly announced its intention to withdraw, modify or qualify) in any
    manner adverse in any respect to Grantee its recommendation that the
    stockholders of Issuer approve the transactions contemplated by the Merger
    Agreement in anticipation of engaging in an Acquisition Transaction, or
    Issuer or any Issuer Subsidiary shall have authorized, recommended, proposed
    (or publicly announced its intention to authorize, recommend or propose) an
    agreement to engage in an Acquisition Transaction with any person other than
    Grantee or a Grantee Subsidiary;

       (v) Any person other than Grantee or any Grantee Subsidiary shall have
    filed with the SEC a registration statement or tender offer materials with
    respect to a potential exchange or tender offer that would constitute an
    Acquisition Transaction (or filed a preliminary proxy statement with the SEC
    with respect to a potential vote by its stockholders to approve the issuance
    of shares to be offered in such an exchange offer);

      (vi) Issuer shall have willfully breached any covenant or obligation
    contained in the Merger Agreement after an overture is made by a third party
    to Issuer or its stockholders to engage in an Acquisition Transaction, and
    (a) following such breach Grantee would be entitled to terminate the Merger
    Agreement (whether immediately or after the giving of notice or passage of
    time or both) and (b) such breach shall not have been cured prior to the
    Notice Date (as defined in Section 2(e)); or

     (vii) Any person other than Grantee or any Grantee Subsidiary, without
    Grantee's prior written consent, shall have filed an application or notice
    with the Board of Governors of the Federal Reserve System (the "Federal
    Reserve Board") or other federal or state bank regulatory or antitrust
    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 (other than Grantee or any Grantee
    Subsidiary) of beneficial ownership of 25% or more of the then outstanding
    Common Stock; or


                                       -3-



<PAGE>



      (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) of the second sentence thereof shall be 25%.

    (d) Issuer shall notify Grantee 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 Issuer shall not
be a condition to the right of the Holder to exercise the Option.

    (e) In the event the Holder is entitled to and wishes to exercise the Option
(or any portion thereof), it shall send to Issuer a written notice (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 60 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 or antitrust agency is required in connection with such
purchase, the Holder shall promptly file the required notice or application for
approval, shall promptly notify Issuer 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.

    (f) At the closing referred to in subsection (e) of this Section 2, the
Holder shall (i) pay to Issuer the aggregate purchase price for the shares of
Common Stock purchased pursuant to the exercise of the Option in immediately
available funds by wire transfer to a bank account designated by Issuer and (ii)
present and surrender this Agreement to Issuer at its principal executive
offices, provided that the failure or refusal of the Issuer to designate such a
bank account or accept surrender of this Agreement shall not preclude the Holder
from exercising the Option.

    (g) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (f) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates representing the number of
shares of Common Stock 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 hereunder.

    (h) Certificates for Common Stock 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 Issuer and to resale restrictions arising under the Securities Act of
    1933, as amended. A copy of


                                       -4-



<PAGE>



    such agreement is on file at the principal office of Issuer and will be
    provided to the holder hereof without charge upon receipt by Issuer of a
    written request therefor."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (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 Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, 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 the retention of such reference in the opinion of counsel to the Holder,
in form and substance reasonably satisfactory to the Issuer; and (iii) the
legend shall be removed in its entirety if the conditions in the preceding
clauses (i) and (ii) are both satisfied. In addition, such certificates shall
bear any other legend as may be required by law.

    (i) Upon the giving by the Holder to Issuer 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 shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
Issuer shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to the Holder. Issuer 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. Issuer agrees: (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock; (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 Issuer;
(iii) promptly to take all action as may from time to time be required
(including (x) complying with all applicable 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 (the "BHCA"), or the Change in Bank Control Act
of 1978, 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


                                       -5-



<PAGE>



Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and
(iv) promptly to take all action provided herein to protect the rights of the
Holder against dilution.

    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 Issuer, 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 shares of Common Stock 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 Issuer 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, Issuer will
execute and deliver a new Agreement of like tenor and date. Any such new
Agreement executed and delivered shall constitute an additional contractual
obligation on the part of Issuer, whether or not the Agreement so lost, stolen,
destroyed or mutilated shall at any time be enforceable by anyone.

    5. In addition to the adjustment in the number of shares of Common Stock
that are purchasable upon exercise of the Option pursuant to Section 1 of this
Agreement, the number of shares of Common Stock purchasable upon the exercise of
the Option and the Option Price shall be subject to adjustment from time to time
as provided in this Section 5. In the event of any change in Common Stock by
reason of a stock dividend, stock split, split-up, recapitalization, stock
combination, exchange of shares or similar transaction, the type and number of
shares or securities subject to the Option, and the Option Price therefor, shall
be adjusted appropriately, and proper provision shall be made in the agreements
governing such transaction so that Grantee shall receive, upon exercise of the
Option, the number and class of shares or other securities or property that
Grantee would have received in respect of Common Stock if the Option had been
exercised immediately prior to such event, or the record date therefor, as
applicable. If any additional shares of Common Stock are issued after the date
of this Agreement (other than pursuant to an event described in the first
sentence of this Section 5), the number of shares of Common Stock subject to the
Option shall be adjusted so that, after such issuance, it, together with any
shares of Common Stock previously issued pursuant hereto, equals 19.9% of the
number of shares of Common Stock then issued and outstanding, without giving
effect to any shares subject to or issued pursuant to the Option.

    6. Upon the occurrence of a Subsequent Triggering Event that occurs prior to
an Exercise Termination Event, Issuer shall, at the request of Grantee delivered
within six (6) months (or such later period as provided in Section 10) of such
Subsequent Triggering Event (whether on its own behalf or on behalf of any
subsequent holder of this Option (or part thereof) or any of the shares of
Common Stock issued pursuant hereto), promptly prepare, file and keep current a
registration statement under the 1933 Act


                                       -6-



<PAGE>



covering any shares issued and issuable pursuant to this Option and shall use
its reasonable best efforts to cause such registration statement to become
effective and remain current in order to permit the sale or other disposition of
any shares of Common Stock issued upon total or partial exercise of this Option
("Option Shares") in accordance with any plan of disposition requested by
Grantee. Issuer will use its reasonable best efforts to cause such registration
statement promptly to become effective and then to remain effective for such
period not in excess of 180 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. Grantee shall have the right to demand two
such registrations. The Issuer shall bear the costs of such registrations
(including, but not limited to, Issuer's attorneys' fees, printing costs and
filing fees, except for underwriting discounts or commissions, brokers' fees and
the fees and disbursements of Grantee's counsel related thereto). The foregoing
notwithstanding, if, at the time of any request by Grantee for registration of
Option Shares as provided above, Issuer is in registration with respect to an
underwritten public offering by Issuer of shares of Common Stock, 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 offer and sale
of the Option Shares would interfere with the successful marketing of the shares
of Common Stock offered by Issuer, 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 33 1/3% of the total number of shares to be sold by the
Holder and Issuer in the aggregate; and provided further, however, that if such
reduction occurs, then Issuer shall file a registration statement for the
balance as promptly as practicable 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 and the twelve (12) month period
referred to in the first sentence of this section shall be increased to
twenty-four (24) months. Each such Holder shall provide all information
reasonably requested by Issuer for inclusion in any registration statement to be
filed hereunder. If requested by any such Holder in connection with such
registration, Issuer shall become a party to any underwriting agreement relating
to the sale of such shares, but only to the extent of obligating itself in
respect of representations, warranties, indemnities and other agreements
customarily included in such underwriting agreements for Issuer. Upon receiving
any request under this Section 6 from any Holder, Issuer agrees to send a copy
thereof to any other person known to Issuer 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. Notwithstanding anything to the contrary contained herein, in no event
shall the number of registrations that Issuer is obligated to effect be
increased by reason of the fact that there shall be more than one Holder as a
result of any assignment or division of this Agreement.

    7. (a) At any time after the occurrence of a Repurchase Event (as defined
below) (i) at the request of the Holder, delivered prior to an Exercise
Termination Event (or such later period as provided in Section 10), Issuer (or
any successor thereto) shall repurchase the Option from the Holder at a price
(the "Option Repurchase Price") equal


                                       -7-



<PAGE>



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 an Exercise Termination Event (or
such later period as provided in Section 10), Issuer (or any successor thereto)
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 "market/offer price" shall mean the highest of (i) the price per share of
Common Stock at which a tender or exchange offer therefor has been made, (ii)
the price per share of Common Stock to be paid by any third party pursuant to an
agreement with Issuer, (iii) the highest closing price for shares of Common
Stock within the six-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 any substantial part of Issuer's 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 Issuer as determined by a
nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to Issuer, divided by the
number of shares of Common Stock of Issuer 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, and reasonably acceptable
to Issuer.

    (b) The Holder and the Owner, as the case may be, may exercise its right to
require Issuer to repurchase the Option and any Option Shares pursuant to this
Section 7 by surrendering for such purpose to Issuer, 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 Issuer to repurchase this Option and/or
the Option Shares in accordance with the provisions of this Section 7. The
Holder shall also represent and warrant that it has sole record and beneficial
ownership of such Option Shares and that such Option Shares are then free and
clear of all liens. As promptly as practicable, and in any event within five (5)
business days after the surrender of the Option and/or certificates representing
Option Shares and the receipt of such notice or notices relating thereto, Issuer
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 Issuer is not then prohibited under applicable law and regulation
from so delivering.

    (c) To the extent that Issuer 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, Issuer 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 five (5) business days
after the date on which Issuer is no longer so prohibited; provided,


                                       -8-



<PAGE>



however, that if Issuer at any time after delivery of a notice of repurchase
pursuant to paragraph (b) of this Section 7 is prohibited under applicable law
or regulation, or as a consequence of administrative policy, from delivering to
the Holder and/or the Owner, as appropriate, the Option Repurchase Price and the
Option Share Repurchase Price, respectively, in full (and Issuer hereby
undertakes to use its reasonable 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 and/or the Option Shares whether in whole or
to the extent of the prohibition, whereupon, in the latter case, Issuer shall
promptly (i) deliver to the Holder and/or the Owner, as appropriate, that
portion of the Option Repurchase Price and/or the Option Share Repurchase Price
that Issuer 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 shares of Common Stock obtained by multiplying the
number of shares of Common Stock 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, and/or (B) to the Owner, a certificate for the Option Shares
it is then so prohibited from repurchasing. If an Exercise Termination Event
shall have occurred prior to the date of the notice by Issuer described in the
first sentence of this subsection (c), or shall be scheduled to occur at any
time before the expiration of a period ending on the thirtieth day after such
date, the Holder shall nonetheless have the right to exercise the Option until
the expiration of such 30-day period.

    (d) For purposes of this Section 7, a "Repurchase Event" shall be deemed to
have occurred upon the occurrence of any of the following events or transactions
after the date hereof:

       (i) the acquisition by any person (other than Grantee or any Grantee
    Subsidiary) of (A) beneficial ownership of 50% or more of the then
    outstanding Common Stock or (B) beneficial ownership of 20% or more of the
    then outstanding Common Stock if Issuer shall have violated Section 6.15 of
    the Merger Agreement; or

      (ii) the consummation of any Acquisition Transaction described in Section
    2(b)(i) hereof, except that the percentage referred to in clause (z) shall
    be 25%.

    8. (a) In the event that prior to an Exercise Termination Event, Issuer
shall enter into an agreement (i) to consolidate with or merge into any person,
other than Grantee or a Grantee Subsidiary, or engage in a plan of exchange with
any person, other than Grantee or a Grantee Subsidiary and Issuer shall not be
the continuing or surviving corporation of such consolidation or merger or the
acquirer in such plan of exchange, (ii) to permit any person, other than Grantee
or a Grantee Subsidiary, to merge into Issuer or be acquired by Issuer in a plan
of exchange and Issuer shall be the continuing or surviving or acquiring
corporation, but, in connection with such merger or plan of exchange, the then
outstanding shares of Common Stock shall be changed into or


                                       -9-



<PAGE>



exchanged for stock or other securities of any other person or cash or any other
property or the then outstanding shares of Common Stock shall after such merger
or plan of exchange represent less than 50% of the outstanding shares and share
equivalents of the merged or acquiring company, or (iii) to sell or otherwise
transfer all or a substantial part of its or any Issuer Subsidiary's assets or
deposits to any person, other than Grantee or a Grantee 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
    person of a consolidation or merger with Issuer (if other than Issuer), (ii)
    the acquiring person in a plan of exchange in which Issuer is acquired,
    (iii) the Issuer in a merger or plan of exchange in which Issuer is the
    continuing or surviving or acquiring person and (iv) the transferee of all
    or a substantial part of Issuer's assets or deposits (or the assets or
    deposits of any Issuer Subsidiary).

       (ii) "Substitute Common Stock" shall mean the common stock 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 a share of
    the Substitute Common Stock for one (1) year immediately preceding the
    consolidation, merger or sale in question, but in no event higher than the
    closing price of the shares of Substitute Common Stock on the day preceding
    such consolidation, merger or sale; provided that if Issuer is the issuer of
    the Substitute Option, the Average Price shall be computed with respect to a
    share of common stock issued by the person merging into Issuer or by any
    company which controls or is controlled by such person, as the Holder may
    elect.

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

    (d) The Substitute Option shall be exercisable for such number of shares of
Substitute Common Stock as is equal to the Assigned Value multiplied by the
number of shares of Common Stock for which the Option was exercisable
immediately prior to the


                                      -10-



<PAGE>



event described in the first sentence of Section 8(a), divided by the Average
Price. The exercise price of the Substitute Option per share of Substitute
Common Stock shall then be equal to the Option Price multiplied by a fraction,
the numerator of which shall be the number of shares of Common Stock for which
the Option was exercisable immediately prior to the event described in the first
sentence of Section 8(a) and the denominator of which shall be the number of
shares of Substitute Common Stock 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 more than 19.9% of the shares of Substitute
Common Stock outstanding prior to exercise of the Substitute Option. In the
event that the Substitute Option would be exercisable for more than 19.9% of the
shares of Substitute Common Stock outstanding prior to exercise but for this
clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer")
shall make a cash payment to Holder equal to the excess of (i) the value of the
Substitute Option without giving effect to the limitation in this clause (e)
over (ii) the value of the Substitute Option after giving effect to the
limitation in this clause (e). This difference in value shall be determined by a
nationally recognized investment banking firm selected by the Holder.

    (f) Issuer shall not enter into any transaction described in subsection (a)
of this Section 8 unless the Acquiring Corporation and any person that controls
the Acquiring Corporation assume in writing all the obligations of Issuer
hereunder.

    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 Issuer") 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 shares of Substitute Common Stock 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 Stock (the "Substitute Shares"), the
Substitute Option Issuer 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 Stock within the six-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 rights to require the Substitute Option
Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to
this Section 9 by surrendering for such purpose to the Substitute Option Issuer,
at its principal office, the agreement for such Substitute Option (or, in the
absence of such an agreement, a copy of this Agreement) and/or certificates for
Substitute Shares accompanied by a written notice or notices stating that the
Substitute Option Holder or the Substitute


                                      -11-



<PAGE>



Share Owner, as the case may be, elects to require the Substitute Option Issuer
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 five (5) 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 Issuer 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
Issuer is not then prohibited under applicable law and regulation from so
delivering.

    (c) To the extent that the Substitute Option Issuer 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 Issuer 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 Option
Repurchase Price and/or the Substitute Share Repurchase Price, respectively,
which it is no longer prohibited from delivering, within five (5) business days
after the date on which the Substitute Option Issuer is no longer so prohibited;
provided, however, that if the Substitute Option Issuer is at any time after
delivery of a notice of repurchase pursuant to subsection (b) of this Section 9
prohibited under applicable law or regulation, or as a consequence of
administrative policy, from delivering to the Substitute Option Holder and/or
the Substitute Share Owner, as appropriate, the Substitute Option Repurchase
Price and the Substitute Share Repurchase Price, respectively, in full (and the
Substitute Option Issuer shall use its reasonable best efforts to receive all
required regulatory and legal approvals as promptly as practicable in order to
accomplish such repurchase), the Substitute Option Holder and/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 prohibition, whereupon, in
the latter case, the Substitute Option Issuer 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 Issuer 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 shares of the Substitute Common Stock obtained by
multiplying the number of shares of the Substitute Common Stock 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, and/or (B) to the Substitute Share Owner, a certificate for
the Substitute Option Shares it is then so prohibited from repurchasing. If an
Exercise Termination Event shall have occurred prior to the date of the notice
by the Substitute Option Issuer described in the first sentence of this
subsection (c), or shall be scheduled to occur at any time before the expiration
of a period ending on the thirtieth day after


                                      -12-



<PAGE>



such date, the Substitute Option Holder shall nevertheless have the right to
exercise the Substitute Option until the expiration of such 30-day period.

    10. The periods for exercise of certain rights under Sections 2, 6, 7, 9 and
14 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, Owner,
Substitute Option Holder or Substitute Share Owner, as the case may be, is using
commercially reasonable efforts to obtain such regulatory approvals), and for
the expiration of all statutory waiting periods; (ii) to the extent necessary to
avoid liability under Section 16(b) of the 1934 Act by reason of such exercise;
and (iii) when there exists an injunction, order or judgment that prohibits or
delays exercise of such right.

    11. (a) Issuer hereby represents and warrants to Grantee as follows:

    (i) Issuer has the requisite corporate power and authority to execute and
deliver this Agreement and to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Issuer Board prior to the date hereof and no other corporate proceedings on the
part of Issuer are necessary to authorize this Agreement or to consummate the
transactions so contemplated. This Agreement has been duly and validly executed
and delivered by Issuer.

    (ii) Issuer 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 shares of
Common Stock equal to the maximum number of shares of Common Stock 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, and will be delivered free and clear of all claims, liens,
encumbrance and security interests and not subject to any preemptive rights.

    (b) Grantee hereby represents and warrants to Issuer as follows: Grantee has
the requisite corporate power and authority to execute and deliver this
Agreement and to perform its obligations hereunder. The execution and delivery
of this Agreement by the Grantee and the performance of its obligations
hereunder by the Grantee have been duly and validly authorized by the Board of
Directors of Grantee and no other corporate proceedings on the part of the
Grantee are necessary to authorize this Agreement or for Grantee to perform its
obligations hereunder. This Agreement has been duly and validly executed and
delivered by Grantee.

    (c) This Option is not being, and any Option Shares or other securities
acquired by Grantee upon exercise of the Option will not be, acquired with a
view to the public distribution thereof and will not be transferred or otherwise
disposed or except in a transaction registered or exempt from registration under
the 1933 Act.

    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 an Initial Triggering Event shall have occurred prior to an Exercise
Termination Event, Grantee, subject to the express provisions hereof, may assign
in whole or in part its rights and obligations hereunder; provided, however,
that until the date fifteen (15) days following the date on which the Federal
Reserve Board has approved an application by Grantee to acquire the shares of
Common Stock subject to the Option, Grantee 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 (e.g., a
broker or investment banker) for the purpose of conducting a widely dispersed
public distribution on Grantee's behalf or (iv) any other manner approved by the
Federal Reserve Board.

    13. Each of Grantee and Issuer will use its reasonable 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 BHCA for approval to acquire the shares issuable hereunder, but
Grantee shall not be obligated to apply to state banking authorities for
approval to acquire the shares of Common Stock issuable hereunder until such
time, if ever, as it deems appropriate to do so.

    14. (a) Grantee may, at any time following a Repurchase Event and prior to
the occurrence of an Exercise Termination Event (or such later period as
provided in Section 10), relinquish the Option (together with any Option Shares
issued to and then owned by Grantee) to Issuer in exchange for a cash fee equal
to the Surrender Price. The "Surrender Price" shall be equal to $225 million (i)
plus, if applicable, Grantee's purchase price with respect to any Option Shares
and (ii) minus, if applicable, the excess of (A) the net price, if any, received
by Grantee or a Grantee Subsidiary pursuant to the sale of Option Shares (or any
other securities into which such Option Shares were converted or exchanged) to
any unaffiliated party, over (B) Grantee's purchase price of such Option Shares.

    (b) Grantee may exercise its right to relinquish the Option and any Option
Shares pursuant to this Section 14 by surrendering to Issuer, at its principal
office, a copy of this Agreement together with certificates for Option Shares,
if any, accompanied by a written notice stating (i) that Grantee elects to
relinquish the Option and Option Shares, if any, in accordance with the
provisions of this Section 14 and (ii) the Surrender Price. The Surrender Price
shall be payable in immediately available funds on or before the second business
day following receipt of such notice by Issuer.

    (c) To the extent that Issuer is prohibited under applicable law or
regulation, or as a consequence of administrative policy, from paying the
Surrender Price to Grantee in full, Issuer shall immediately so notify Grantee
and thereafter deliver or cause to be delivered, from time to time, to Grantee,
the portion of the Surrender Price that it is no longer prohibited from paying,
within five (5) business days after the date on which


                                      -14-



<PAGE>



Issuer is no longer so prohibited; provided, however, that if Issuer at any time
after delivery of a notice of surrender pursuant to paragraph (b) of this
Section 14 is prohibited under applicable law or regulation, or as a consequence
of administrative policy, from paying to Grantee the Surrender Price in full,
(i) Issuer shall (A) use its reasonable best efforts to obtain all required
regulatory and legal approvals and to file any required notices as promptly as
practicable in order to make such payments, (B) within five (5) days of the
submission or receipt of any documents relating to any such regulatory and legal
approvals, provide Grantee with copies of the same and (c) keep Grantee advised
of both the status of any such request for regulatory and legal approvals, as
well as any discussions with any relevant regulatory or other third party
reasonably related to the same and (ii) Grantee may revoke such notice of
surrender by delivery of a notice of revocation to Issuer and, upon delivery of
such notice of revocation, the Exercise Termination Date shall be extended to a
date six (6) months from the date on which the Exercise Termination Date would
have occurred if not for the provisions of this Section 14(c) (during which
period Grantee may exercise any of its rights hereunder, including any and all
rights pursuant to this Section 14).

    15. The parties hereto acknowledge that damages would be an inadequate
remedy for a breach of this Agreement by either party hereto and that the
obligations of the parties hereto shall be enforceable by either party hereto
through injunctive or other equitable relief. In connection therewith, both
parties waive the posting of any bond or similar requirement.

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

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

    18. This Agreement shall be governed by and construed in accordance with the
laws of the State of Delaware.

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

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

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

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

    IN WITNESS WHEREOF, each of the parties has caused this Agreement to be
executed on its behalf by its officers thereunto duly authorized, all as of the
date first above written.

                             STOCK OPTION AGREEMENT

    STOCK OPTION AGREEMENT, dated as of June 1, 1999 (this "Agreement"), between
AmSouth Bancorporation, a Delaware corporation ("Grantee"), and First American
Corporation, a Tennessee corporation ("Issuer").

                                    RECITALS

        A. Merger Agreement. Grantee and Issuer have entered into an Agreement
and Plan of Merger, dated as of May 31, 1999 (the "Merger Agreement"), which
agreement was executed and delivered on the day preceding the date of this Stock
Option Agreement; and

        B. Option. As a condition to Grantee's entering into the Merger
Agreement and in consideration therefor, Issuer has agreed to grant Grantee 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) Issuer hereby grants to Grantee an unconditional, irrevocable option
(the "Option") to purchase, subject to the terms hereof, up to an aggregate of
23,250,165 fully paid and nonassessable shares of the common stock, par value
$2.50 per share, of Issuer ("Common Stock") at a price per share equal to
$40.1625; provided, however, that in no event shall the number of shares for
which this Option is exercisable exceed 19.9% of the issued and outstanding
shares of Common Stock. The number of shares of Common Stock 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 shares of Common Stock are issued or
otherwise become outstanding after the date of this Agreement (other than
pursuant to this Agreement and other than pursuant to an event described in
Section 5(a) hereof), the number of shares of Common Stock subject to the Option
shall be increased so that, after such issuance, such number together with any
shares of Common Stock previously issued pursuant hereto, equals 19.9% of the
number of shares of Common Stock then issued and outstanding without giving
effect to any shares subject or issued pursuant to the Option. Nothing contained
in this Section l(b) or elsewhere in this Agreement shall be deemed to authorize
Issuer to issue shares in breach of any provision of the Merger Agreement.

    2. (a) The Holder (as hereinafter defined) may exercise the Option, 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), provided that the Holder shall have sent the written
notice of such exercise (as provided in subsection (e) of



<PAGE>



this Section 2) within six (6) months following such Subsequent Triggering Event
(or such later period as provided in Section 10). Each of the following shall be
an Exercise Termination Event: (i) the Effective Time 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
except a termination by Grantee pursuant to Section 8.01(b) of the Merger
Agreement (unless the breach by Issuer giving rise to such right of termination
is non-volitional) (a "Listed Termination"); or (iii) the passage of eighteen
(18) 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 is a Listed Termination. The term "Holder" shall mean the
holder or holders of the Option. Notwithstanding anything to the contrary
contained herein, the Option may not be exercised at any time when Grantee shall
be in material breach of any of its covenants or agreements contained in the
Merger Agreement such that Issuer shall be entitled to terminate the Merger
Agreement pursuant to Section 8.01(b) thereof.

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

        (i) Issuer or any of its Significant Subsidiaries (as defined in Rule
    1-02 of Regulation S-X promulgated by the Securities and Exchange Commission
    (the "SEC")) (the "Issuer Subsidiaries"), without having received Grantee'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, as
    amended (the "1934 Act"), and the rules and regulations thereunder) other
    than Grantee or any of its Subsidiaries (each a "Grantee Subsidiary") or the
    Board of Directors of Issuer (the "Issuer Board") shall have recommended
    that the stockholders of Issuer approve or accept any Acquisition
    Transaction other than as contemplated by the Merger Agreement. For purposes
    of this Agreement, (a) "Acquisition Transaction" shall mean (x) a merger or
    consolidation, or any similar transaction, involving Issuer or any Issuer
    Subsidiary (other than mergers, consolidations or similar transactions
    involving solely Issuer and/or one or more wholly-owned Subsidiaries of the
    Issuer, provided, any such transaction is not entered into in violation of
    the terms of the Merger Agreement), (y) a purchase, lease or other
    acquisition of all or any substantial part of the assets or deposits of
    Issuer or any Issuer Subsidiary, or (z) a purchase or other acquisition
    (including by way of merger, consolidation, share exchange or otherwise) of
    securities representing 10% or more of the voting power of Issuer or any
    Issuer Subsidiary and (b) "Subsidiary" shall have the meaning set forth in
    Rule 12b-2 under the 1934 Act;

        (ii) Any person other than the Grantee or any Grantee Subsidiary shall
    have acquired beneficial ownership or the right to acquire beneficial
    ownership of 10% or more of the outstanding shares of Common Stock (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);


                                       -2-

<PAGE>



        (iii) The stockholders of Issuer shall have voted and failed to approve
    the Merger Agreement and the Merger at a meeting which has been held for
    that purpose or any adjournment or postponement thereof, or such meeting
    shall not have been held in violation of the Merger Agreement or shall have
    been canceled prior to termination of the Merger Agreement if, prior to such
    meeting (or if such meeting shall not have been held or shall have been
    canceled, prior to such termination), it shall have been publicly announced
    that any person (other than Grantee or any of its Subsidiaries) shall have
    made, or disclosed an intention to make, a proposal to engage in an
    Acquisition Transaction;

        (iv) The Issuer Board shall have withdrawn, modified or qualified (or
    publicly announced its intention to withdraw, modify or qualify) in any
    manner adverse in any respect to Grantee its recommendation that the
    stockholders of Issuer approve the transactions contemplated by the Merger
    Agreement in anticipation of engaging in an Acquisition Transaction, or
    Issuer or any Issuer Subsidiary shall have authorized, recommended, proposed
    (or publicly announced its intention to authorize, recommend or propose) an
    agreement to engage in an Acquisition Transaction with any person other than
    Grantee or a Grantee Subsidiary;

        (v) Any person other than Grantee or any Grantee Subsidiary shall have
    filed with the SEC a registration statement or tender offer materials with
    respect to a potential exchange or tender offer that would constitute an
    Acquisition Transaction (or filed a preliminary proxy statement with the SEC
    with respect to a potential vote by its stockholders to approve the issuance
    of shares to be offered in such an exchange offer);

        (vi) Issuer shall have willfully breached any covenant or obligation
    contained in the Merger Agreement after an overture is made by a third party
    to Issuer or its stockholders to engage in an Acquisition Transaction, and
    (a) following such breach Grantee would be entitled to terminate the Merger
    Agreement (whether immediately or after the giving of notice or passage of
    time or both) and (b) such breach shall not have been cured prior to the
    Notice Date (as defined in Section 2(e)); or

        (vii) Any person other than Grantee or any Grantee Subsidiary, without
    Grantee's prior written consent, shall have filed an application or notice
    with the Board of Governors of the Federal Reserve System (the "Federal
    Reserve Board") or other federal or state bank regulatory or antitrust
    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 (other than Grantee or any Grantee
    Subsidiary) of beneficial ownership of 25% or more of the then outstanding
    Common Stock; or


                                       -3-

<PAGE>



        (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) of the second sentence thereof shall be 25%.

    (d) Issuer shall notify Grantee 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 Issuer shall not
be a condition to the right of the Holder to exercise the Option.

    (e) In the event the Holder is entitled to and wishes to exercise the Option
(or any portion thereof), it shall send to Issuer a written notice (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 60 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 or antitrust agency is required in connection with such
purchase, the Holder shall promptly file the required notice or application for
approval, shall promptly notify Issuer 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.

    (f) At the closing referred to in subsection (e) of this Section 2, the
Holder shall (i) pay to Issuer the aggregate purchase price for the shares of
Common Stock purchased pursuant to the exercise of the Option in immediately
available funds by wire transfer to a bank account designated by Issuer and (ii)
present and surrender this Agreement to Issuer at its principal executive
offices, provided that the failure or refusal of the Issuer to designate such a
bank account or accept surrender of this Agreement shall not preclude the Holder
from exercising the Option.

    (g) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (f) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates representing the number of
shares of Common Stock 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 hereunder.

    (h) Certificates for Common Stock 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 Issuer and to resale restrictions arising under the Securities Act of
    1933, as amended. A copy of


                                       -4-


<PAGE>



    such agreement is on file at the principal office of Issuer and will be
    provided to the holder hereof without charge upon receipt by Issuer of a
    written request therefor."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (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 Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, 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 the retention of such reference in the opinion of counsel to the Holder,
in form and substance reasonably satisfactory to the Issuer; and (iii) the
legend shall be removed in its entirety if the conditions in the preceding
clauses (i) and (ii) are both satisfied. In addition, such certificates shall
bear any other legend as may be required by law.

    (i) Upon the giving by the Holder to Issuer 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 shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
Issuer shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to the Holder. Issuer 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. Issuer agrees: (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock; (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 Issuer;
(iii) promptly to take all action as may from time to time be required
(including (x) complying with all applicable 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 (the "BHCA"), or the Change in Bank Control Act
of 1978, 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


                                       -5-


<PAGE>



Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and
(iv) promptly to take all action provided herein to protect the rights of the
Holder against dilution.

    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 Issuer, 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 shares of Common Stock 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 Issuer 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, Issuer will
execute and deliver a new Agreement of like tenor and date. Any such new
Agreement executed and delivered shall constitute an additional contractual
obligation on the part of Issuer, whether or not the Agreement so lost, stolen,
destroyed or mutilated shall at any time be enforceable by anyone.

    5. In addition to the adjustment in the number of shares of Common Stock
that are purchasable upon exercise of the Option pursuant to Section 1 of this
Agreement, the number of shares of Common Stock purchasable upon the exercise of
the Option and the Option Price shall be subject to adjustment from time to time
as provided in this Section 5. In the event of any change in Common Stock by
reason of a stock dividend, stock split, split-up, recapitalization, stock
combination, exchange of shares or similar transaction, the type and number of
shares or securities subject to the Option, and the Option Price therefor, shall
be adjusted appropriately, and proper provision shall be made in the agreements
governing such transaction so that Grantee shall receive, upon exercise of the
Option, the number and class of shares or other securities or property that
Grantee would have received in respect of Common Stock if the Option had been
exercised immediately prior to such event, or the record date therefor, as
applicable. If any additional shares of Common Stock are issued after the date
of this Agreement (other than pursuant to an event described in the first
sentence of this Section 5), the number of shares of Common Stock subject to the
Option shall be adjusted so that, after such issuance, it, together with any
shares of Common Stock previously issued pursuant hereto, equals 19.9% of the
number of shares of Common Stock then issued and outstanding, without giving
effect to any shares subject to or issued pursuant to the Option.

    6. Upon the occurrence of a Subsequent Triggering Event that occurs prior to
an Exercise Termination Event, Issuer shall, at the request of Grantee delivered
within six (6) months (or such later period as provided in Section 10) of such
Subsequent Triggering Event (whether on its own behalf or on behalf of any
subsequent holder of this Option (or part thereof) or any of the shares of
Common Stock issued pursuant hereto), promptly prepare, file and keep current a
registration statement under the 1933 Act


                                       -6-

<PAGE>



covering any shares issued and issuable pursuant to this Option and shall use
its reasonable best efforts to cause such registration statement to become
effective and remain current in order to permit the sale or other disposition of
any shares of Common Stock issued upon total or partial exercise of this Option
("Option Shares") in accordance with any plan of disposition requested by
Grantee. Issuer will use its reasonable best efforts to cause such registration
statement promptly to become effective and then to remain effective for such
period not in excess of 180 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. Grantee shall have the right to demand two
such registrations. The Issuer shall bear the costs of such registrations
(including, but not limited to, Issuer's attorneys' fees, printing costs and
filing fees, except for underwriting discounts or commissions, brokers' fees and
the fees and disbursements of Grantee's counsel related thereto). The foregoing
notwithstanding, if, at the time of any request by Grantee for registration of
Option Shares as provided above, Issuer is in registration with respect to an
underwritten public offering by Issuer of shares of Common Stock, 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 offer and sale
of the Option Shares would interfere with the successful marketing of the shares
of Common Stock offered by Issuer, 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 33 1/3% of the total number of shares to be sold by the
Holder and Issuer in the aggregate; and provided further, however, that if such
reduction occurs, then Issuer shall file a registration statement for the
balance as promptly as practicable 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 and the twelve (12) month period
referred to in the first sentence of this section shall be increased to
twenty-four (24) months. Each such Holder shall provide all information
reasonably requested by Issuer for inclusion in any registration statement to be
filed hereunder. If requested by any such Holder in connection with such
registration, Issuer shall become a party to any underwriting agreement relating
to the sale of such shares, but only to the extent of obligating itself in
respect of representations, warranties, indemnities and other agreements
customarily included in such underwriting agreements for Issuer. Upon receiving
any request under this Section 6 from any Holder, Issuer agrees to send a copy
thereof to any other person known to Issuer 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. Notwithstanding anything to the contrary contained herein, in no event
shall the number of registrations that Issuer is obligated to effect be
increased by reason of the fact that there shall be more than one Holder as a
result of any assignment or division of this Agreement.

    7. (a) At any time after the occurrence of a Repurchase Event (as defined
below) (i) at the request of the Holder, delivered prior to an Exercise
Termination Event (or such later period as provided in Section 10), Issuer (or
any successor thereto) shall repurchase the Option from the Holder at a price
(the "Option Repurchase Price") equal


                                       -7-

<PAGE>



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 an Exercise Termination Event (or
such later period as provided in Section 10), Issuer (or any successor thereto)
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 "market/offer price" shall mean the highest of (i) the price per share of
Common Stock at which a tender or exchange offer therefor has been made, (ii)
the price per share of Common Stock to be paid by any third party pursuant to an
agreement with Issuer, (iii) the highest closing price for shares of Common
Stock within the six-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 any substantial part of Issuer's 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 Issuer as determined by a
nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to Issuer, divided by the
number of shares of Common Stock of Issuer 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, and reasonably acceptable
to Issuer.

    (b) The Holder and the Owner, as the case may be, may exercise its right to
require Issuer to repurchase the Option and any Option Shares pursuant to this
Section 7 by surrendering for such purpose to Issuer, 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 Issuer to repurchase this Option and/or
the Option Shares in accordance with the provisions of this Section 7. The
Holder shall also represent and warrant that it has sole record and beneficial
ownership of such Option Shares and that such Option Shares are then free and
clear of all liens. As promptly as practicable, and in any event within five (5)
business days after the surrender of the Option and/or certificates representing
Option Shares and the receipt of such notice or notices relating thereto, Issuer
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 Issuer is not then prohibited under applicable law and regulation
from so delivering.

    (c) To the extent that Issuer 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, Issuer 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 five (5) business days
after the date on which Issuer is no longer so prohibited; provided,


                                       -8-


<PAGE>



however, that if Issuer at any time after delivery of a notice of repurchase
pursuant to paragraph (b) of this Section 7 is prohibited under applicable law
or regulation, or as a consequence of administrative policy, from delivering to
the Holder and/or the Owner, as appropriate, the Option Repurchase Price and the
Option Share Repurchase Price, respectively, in full (and Issuer hereby
undertakes to use its reasonable 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 and/or the Option Shares whether in whole or
to the extent of the prohibition, whereupon, in the latter case, Issuer shall
promptly (i) deliver to the Holder and/or the Owner, as appropriate, that
portion of the Option Repurchase Price and/or the Option Share Repurchase Price
that Issuer 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 shares of Common Stock obtained by multiplying the
number of shares of Common Stock 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, and/or (B) to the Owner, a certificate for the Option Shares
it is then so prohibited from repurchasing. If an Exercise Termination Event
shall have occurred prior to the date of the notice by Issuer described in the
first sentence of this subsection (c), or shall be scheduled to occur at any
time before the expiration of a period ending on the thirtieth day after such
date, the Holder shall nonetheless have the right to exercise the Option until
the expiration of such 30-day period.

    (d) For purposes of this Section 7, a "Repurchase Event" shall be deemed to
have occurred upon the occurrence of any of the following events or transactions
after the date hereof:

        (i) the acquisition by any person (other than Grantee or any Grantee
    Subsidiary) of (A) beneficial ownership of 50% or more of the then
    outstanding Common Stock or (B) beneficial ownership of 20% or more of the
    then outstanding Common Stock if Issuer shall have violated Section 6.15 of
    the Merger Agreement; or

        (ii)the consummation of any Acquisition Transaction described in Section
    2(b)(i) hereof, except that the percentage referred to in clause (z) shall
    be 25%.

    8. (a) In the event that prior to an Exercise Termination Event, Issuer
shall enter into an agreement (i) to consolidate with or merge into any person,
other than Grantee or a Grantee Subsidiary, or engage in a plan of exchange with
any person, other than Grantee or a Grantee Subsidiary and Issuer shall not be
the continuing or surviving corporation of such consolidation or merger or the
acquirer in such plan of exchange, (ii) to permit any person, other than Grantee
or a Grantee Subsidiary, to merge into Issuer or be acquired by Issuer in a plan
of exchange and Issuer shall be the continuing or surviving or acquiring
corporation, but, in connection with such merger or plan of exchange, the then
outstanding shares of Common Stock shall be changed into or


                                       -9-


<PAGE>



exchanged for stock or other securities of any other person or cash or any other
property or the then outstanding shares of Common Stock shall after such merger
or plan of exchange represent less than 50% of the outstanding shares and share
equivalents of the merged or acquiring company, or (iii) to sell or otherwise
transfer all or a substantial part of its or any Issuer Subsidiary's assets or
deposits to any person, other than Grantee or a Grantee 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
    person of a consolidation or merger with Issuer (if other than Issuer), (ii)
    the acquiring person in a plan of exchange in which Issuer is acquired,
    (iii) the Issuer in a merger or plan of exchange in which Issuer is the
    continuing or surviving or acquiring person and (iv) the transferee of all
    or a substantial part of Issuer's assets or deposits (or the assets or
    deposits of any Issuer Subsidiary).

        (ii) "Substitute Common Stock" shall mean the common stock 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 a share of
    the Substitute Common Stock for one (1) year immediately preceding the
    consolidation, merger or sale in question, but in no event higher than the
    closing price of the shares of Substitute Common Stock on the day preceding
    such consolidation, merger or sale; provided that if Issuer is the issuer of
    the Substitute Option, the Average Price shall be computed with respect to a
    share of common stock issued by the person merging into Issuer or by any
    company which controls or is controlled by such person, as the Holder may
    elect.

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

    (d) The Substitute Option shall be exercisable for such number of shares of
Substitute Common Stock as is equal to the Assigned Value multiplied by the
number of shares of Common Stock for which the Option was exercisable
immediately prior to the


                                      -10-


<PAGE>



event described in the first sentence of Section 8(a), divided by the Average
Price. The exercise price of the Substitute Option per share of Substitute
Common Stock shall then be equal to the Option Price multiplied by a fraction,
the numerator of which shall be the number of shares of Common Stock for which
the Option was exercisable immediately prior to the event described in the first
sentence of Section 8(a) and the denominator of which shall be the number of
shares of Substitute Common Stock 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 more than 19.9% of the shares of Substitute
Common Stock outstanding prior to exercise of the Substitute Option. In the
event that the Substitute Option would be exercisable for more than 19.9% of the
shares of Substitute Common Stock outstanding prior to exercise but for this
clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer")
shall make a cash payment to Holder equal to the excess of (i) the value of the
Substitute Option without giving effect to the limitation in this clause (e)
over (ii) the value of the Substitute Option after giving effect to the
limitation in this clause (e). This difference in value shall be determined by a
nationally recognized investment banking firm selected by the Holder.

    (f) Issuer shall not enter into any transaction described in subsection (a)
of this Section 8 unless the Acquiring Corporation and any person that controls
the Acquiring Corporation assume in writing all the obligations of Issuer
hereunder.

    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 Issuer") 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 shares of Substitute Common Stock 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 Stock (the "Substitute Shares"), the
Substitute Option Issuer 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 Stock within the six-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 rights to require the Substitute Option
Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to
this Section 9 by surrendering for such purpose to the Substitute Option Issuer,
at its principal office, the agreement for such Substitute Option (or, in the
absence of such an agreement, a copy of this Agreement) and/or certificates for
Substitute Shares accompanied by a written notice or notices stating that the
Substitute Option Holder or the Substitute


                                      -11-


<PAGE>



Share Owner, as the case may be, elects to require the Substitute Option Issuer
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 five (5) 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 Issuer 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
Issuer is not then prohibited under applicable law and regulation from so
delivering.

    (c) To the extent that the Substitute Option Issuer 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 Issuer 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 Option
Repurchase Price and/or the Substitute Share Repurchase Price, respectively,
which it is no longer prohibited from delivering, within five (5) business days
after the date on which the Substitute Option Issuer is no longer so prohibited;
provided, however, that if the Substitute Option Issuer is at any time after
delivery of a notice of repurchase pursuant to subsection (b) of this Section 9
prohibited under applicable law or regulation, or as a consequence of
administrative policy, from delivering to the Substitute Option Holder and/or
the Substitute Share Owner, as appropriate, the Substitute Option Repurchase
Price and the Substitute Share Repurchase Price, respectively, in full (and the
Substitute Option Issuer shall use its reasonable best efforts to receive all
required regulatory and legal approvals as promptly as practicable in order to
accomplish such repurchase), the Substitute Option Holder and/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 prohibition, whereupon, in
the latter case, the Substitute Option Issuer 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 Issuer 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 shares of the Substitute Common Stock obtained by
multiplying the number of shares of the Substitute Common Stock 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, and/or (B) to the Substitute Share Owner, a certificate for
the Substitute Option Shares it is then so prohibited from repurchasing. If an
Exercise Termination Event shall have occurred prior to the date of the notice
by the Substitute Option Issuer described in the first sentence of this
subsection (c), or shall be scheduled to occur at any time before the expiration
of a period ending on the thirtieth day after


                                      -12-


<PAGE>



such date, the Substitute Option Holder shall nevertheless have the right to
exercise the Substitute Option until the expiration of such 30-day period.

    10. The periods for exercise of certain rights under Sections 2, 6, 7, 9 and
14 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, Owner,
Substitute Option Holder or Substitute Share Owner, as the case may be, is using
commercially reasonable efforts to obtain such regulatory approvals), and for
the expiration of all statutory waiting periods; (ii) to the extent necessary to
avoid liability under Section 16(b) of the 1934 Act by reason of such exercise;
and (iii) when there exists an injunction, order or judgment that prohibits or
delays exercise of such right.

    11. (a) Issuer hereby represents and warrants to Grantee as follows:

    (i) Issuer has the requisite corporate power and authority to execute and
deliver this Agreement and to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Issuer Board prior to the date hereof and no other corporate proceedings on the
part of Issuer are necessary to authorize this Agreement or to consummate the
transactions so contemplated. This Agreement has been duly and validly executed
and delivered by Issuer.

    (ii)Issuer 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 shares of Common
Stock equal to the maximum number of shares of Common Stock 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, and
will be delivered free and clear of all claims, liens, encumbrance and security
interests and not subject to any preemptive rights.

    (b) Grantee hereby represents and warrants to Issuer as follows: Grantee has
the requisite corporate power and authority to execute and deliver this
Agreement and to perform its obligations hereunder. The execution and delivery
of this Agreement by the Grantee and the performance of its obligations
hereunder by the Grantee have been duly and validly authorized by the Board of
Directors of Grantee and no other corporate proceedings on the part of the
Grantee are necessary to authorize this Agreement or for Grantee to perform its
obligations hereunder. This Agreement has been duly and validly executed and
delivered by Grantee.

    (c) This Option is not being, and any Option Shares or other securities
acquired by Grantee upon exercise of the Option will not be, acquired with a
view to the public distribution thereof and will not be transferred or otherwise
disposed or except in a transaction registered or exempt from registration under
the 1933 Act.



                                      -13-


<PAGE>



    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 an Initial Triggering Event shall have occurred prior to an Exercise
Termination Event, Grantee, subject to the express provisions hereof, may assign
in whole or in part its rights and obligations hereunder; provided, however,
that until the date fifteen (15) days following the date on which the Federal
Reserve Board has approved an application by Grantee to acquire the shares of
Common Stock subject to the Option, Grantee 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 (e.g., a
broker or investment banker) for the purpose of conducting a widely dispersed
public distribution on Grantee's behalf or (iv) any other manner approved by the
Federal Reserve Board.

    13. Each of Grantee and Issuer will use its reasonable 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 BHCA for approval to acquire the shares issuable hereunder, but
Grantee shall not be obligated to apply to state banking authorities for
approval to acquire the shares of Common Stock issuable hereunder until such
time, if ever, as it deems appropriate to do so.

    14. (a) Grantee may, at any time following a Repurchase Event and prior to
the occurrence of an Exercise Termination Event (or such later period as
provided in Section 10), relinquish the Option (together with any Option Shares
issued to and then owned by Grantee) to Issuer in exchange for a cash fee equal
to the Surrender Price. The "Surrender Price" shall be equal to $225 million (i)
plus, if applicable, Grantee's purchase price with respect to any Option Shares
and (ii) minus, if applicable, the excess of (A) the net price, if any, received
by Grantee or a Grantee Subsidiary pursuant to the sale of Option Shares (or any
other securities into which such Option Shares were converted or exchanged) to
any unaffiliated party, over (B) Grantee's purchase price of such Option Shares.

    (b) Grantee may exercise its right to relinquish the Option and any Option
Shares pursuant to this Section 14 by surrendering to Issuer, at its principal
office, a copy of this Agreement together with certificates for Option Shares,
if any, accompanied by a written notice stating (i) that Grantee elects to
relinquish the Option and Option Shares, if any, in accordance with the
provisions of this Section 14 and (ii) the Surrender Price. The Surrender Price
shall be payable in immediately available funds on or before the second business
day following receipt of such notice by Issuer.

    (c) To the extent that Issuer is prohibited under applicable law or
regulation, or as a consequence of administrative policy, from paying the
Surrender Price to Grantee in full, Issuer shall immediately so notify Grantee
and thereafter deliver or cause to be delivered, from time to time, to Grantee,
the portion of the Surrender Price that it is no longer prohibited from paying,
within five (5) business days after the date on which


                                      -14-


<PAGE>



Issuer is no longer so prohibited; provided, however, that if Issuer at any time
after delivery of a notice of surrender pursuant to paragraph (b) of this
Section 14 is prohibited under applicable law or regulation, or as a consequence
of administrative policy, from paying to Grantee the Surrender Price in full,
(i) Issuer shall (A) use its reasonable best efforts to obtain all required
regulatory and legal approvals and to file any required notices as promptly as
practicable in order to make such payments, (B) within five (5) days of the
submission or receipt of any documents relating to any such regulatory and legal
approvals, provide Grantee with copies of the same and (c) keep Grantee advised
of both the status of any such request for regulatory and legal approvals, as
well as any discussions with any relevant regulatory or other third party
reasonably related to the same and (ii) Grantee may revoke such notice of
surrender by delivery of a notice of revocation to Issuer and, upon delivery of
such notice of revocation, the Exercise Termination Date shall be extended to a
date six (6) months from the date on which the Exercise Termination Date would
have occurred if not for the provisions of this Section 14(c) (during which
period Grantee may exercise any of its rights hereunder, including any and all
rights pursuant to this Section 14).

    15. The parties hereto acknowledge that damages would be an inadequate
remedy for a breach of this Agreement by either party hereto and that the
obligations of the parties hereto shall be enforceable by either party hereto
through injunctive or other equitable relief. In connection therewith, both
parties waive the posting of any bond or similar requirement.

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

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

    18. This Agreement shall be governed by and construed in accordance with the
laws of the State of Delaware.

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

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

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

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