ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         It is presently anticipated that, should any purchase of First Security
         Common Stock be made by Zions pursuant to the Option Agreement
         described below in response to Item 4, or otherwise, the source of any
         funds used in any such purchase would be the available cash, cash
         equivalents, available for sale securities and bank financing of Zions.

ITEM 4.  PURPOSE OF TRANSACTION.

         A. THE MERGER AGREEMENT.

         On June 6, 1999, Zions and First Security entered into an Agreement and
         Plan of Merger (the "Merger Agreement") pursuant to which Zions agreed
         to merge with and into First Security (the "Merger"), with First
         Security as the surviving corporation (the "Surviving Corporation").
         The Merger is subject to receipt of regulatory approval, as well as an
         affirmative vote of the shareholders of Zions and First Security and
         certain other closing conditions. It is currently estimated that the




<PAGE>


- ---------------------                                        -------------------
CUSIP NO. 0003362941                   13D                    PAGE 5 OF 17 PAGES
- ---------------------                                        -------------------

         Merger will be consummated in the fourth quarter of 1999, subject to
         satisfaction of such closing conditions.

         The terms of the Merger Agreement provide for a reverse stock split
         immediately prior to the Effective Time of the Merger (as defined in
         the Merger Agreement), in which each outstanding share of First
         Security Common Stock will be converted and reclassified as 0.442 of a
         share of the Surviving Corporation Common Stock. Holders of Zions
         common stock, no par value per share ("Zions Common Stock"), will then
         receive, in exchange for each share of Zions Common Stock (other than
         certain excluded shares) one share of the Surviving Corporation Common
         Stock. Upon consummation of the Merger, the articles of incorporation
         and by-laws of First Security, amended and restated as of the Effective
         Time, will be the articles of incorporation and by-laws of the
         Surviving Corporation. The Board of Directors of the Surviving
         Corporation, as described in Exhibit B to the Merger Agreement, shall
         be composed of 22 members, 11 designated by Zions and 11 designated by
         First Security.

         The Merger is subject to the approval of the Board of Governors of the
         Federal Reserve Board (the "Federal Reserve Board"), the approval of
         the shareholders of Zions, the approval of the stockholders of First
         Security, and the satisfaction of various other terms and conditions
         set forth in the Merger Agreement.

         B. THE OPTION.

         As an inducement and a condition to Zions' entering into the Merger
         Agreement, on June 8, 1999, First Security and Zions entered into a
         Stock Option Agreement (the "Option Agreement") (replacing an earlier
         stock option agreement executed on June 6, 1999), pursuant to which
         First Security granted Zions an option (the "Option") entitling it to
         purchase up to 38,798,410 (or such lesser amount as shall constitute
         19.9% of the outstanding shares of Zions Common Stock on the date of
         exercise) fully paid and nonassessable shares of Zions Common Stock at
         a price per share equal to the average of the last sales price per
         share of First Security Common Stock on the NASDAQ National Market on
         June 4 and June 7, 1999 (the

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

         "Option Price"), subject to adjustment in certain circumstances.*

         Subject to applicable law, regulatory restrictions and other certain
         conditions, Zions may exercise the Option, in whole or in part, after
         the occurrence of an Initial Triggering event (as defined below), and a
         Subsequent Triggering Event (as defined below) and prior to an Exercise
         Termination Event (as defined below), provided that: (i) Zions shall
         have sent the written notice of such exercise (as described under the
         notice provisions below) within six months of such Subsequent
         Triggering Event, and (ii) Zions shall not be in material breach of any
         of its covenants or agreements contained in the Merger Agreement such
         that First Security shall be entitled to terminate the Merger Agreement
         pursuant to Section 8.01(b) thereof. At no point may the Option be
         exercised, as a whole or in part, to the extent that such exercise (or
         the acquisition of Option Shares thereunder) would, if it occurred on
         the date hereof, be inconsistent with any provision of the Merger
         Agreement.

- --------

*    In the event of any change in the First Security Common Stock by reason of
stock dividends, stock splits, split-ups, recapitalizations, stock combinations,
exchanges of shares, or the like, 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 Zions shall receive, upon exercise of the Option, the
number and class of shares or other securities or property that Zions would have
received in respect of the First Security 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 the First Security Common Stock are
issued after the date of the Option Agreement (other than pursuant to an event
described in the preceding sentence), the number of shares of First Security
Common Stock subject to the Option shall be adjusted so that, after such
issuance, it, together with any shares of First Security Common Stock previously
issued pursuant hereto, equals 19.9% of the number of shares of the First
Security Common Stock then issued and outstanding, without giving effect to any
shares subject to or issued pursuant to the Option.

         As defined in the Option Agreement, "Initial Triggering Event," means
         the occurrence of any of the following events or transactions:

          1.   First Security or any of its Significant Subsidiaries (as defined
               in Rule 1-02 of Regulation S-X)(the "First Security
               Subsidiaries"), without having received Zions' prior written
               consent, (i) shall have entered into an agreement to engage in an
               Acquisition Transaction (as defined below) with any person (the
               term "person," as used in the Option Agreement, has the meaning
               assigned thereto in Sections 3(a)(9) and 13(d)(3) of the
               Securities Exchange Act of 1934, as amended, and the rules and
               regulations thereunder), other than Zions or any subsidiary of
               Zions, or (ii) the Board of Directors of First Security shall
               have recommended that the stockholders of First Security approve
               or accept any Acquisition Transaction other than as contemplated
               by the Merger Agreement. For purposes of the Option Agreement,
               "Acquisition Transaction," as defined in the Option Agreement,
               means (x) a merger or consolidation, or any similar transaction,
               involving First Security or any First Security Subsidiary (other
               than such transactions involving solely First Security and/or one
               or more wholly-owned Subsidiaries of First Security, provided
               that 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 a substantial part of the assets or
               deposits of First Security or any First Security 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 First Security or
               any First Security Subsidiary;

          2.   Any person (other than Zions or any subsidiary of Zions) shall
               have acquired Beneficial Ownership or the right to acquire
               Beneficial Ownership, of 10% or more of the outstanding shares of
               First Security Common Stock (the term "Beneficial Ownership" as
               used in the Option Agreement has the meaning assigned thereto in
               Section 13(d) of the

          3.   The stockholders of First Security shall have voted and failed to
               approve the Merger Agreement and the Merger at a meeting of such
               stockholders held for the purpose of voting on the Merger
               Agreement, 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 Zions or any subsidiary of Zions) shall have
               made, or disclosed an intention to make, a proposal to engage in
               an Acquisition Transaction.

          4.   First Security's Board of Directors shall have withdrawn or
               modified (or publicly announced its intention to withdraw, modify
               or qualify) in any manner adverse in any respect to Zions its
               recommendation that the stockholders of First Security approve
               the transactions contemplated by the Merger Agreement, or First
               Security or any First Security 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 Zions or a
               Zions Subsidiary.

          5.   Any person other than Zions or any Zions Subsidiary shall have
               filed with the SEC a registration statement or tender offer
               materials with respect to a potential exchange or tender offer

               Merger Agreement in anticipation of an Acquisition Transaction,
               and following such breach Zions would be entitled to terminate
               the Merger Agreement (whether immediately or after the giving of
               notice or passage of time or both); or

          7.   Any person (other than Zions or any subsidiary of Zions), without
               Zions' prior written consent, shall have filed an application or
               notice with the Board of Governors of the Federal Reserve System
               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.


               As defined in the Option Agreement, "Subsequent Triggering
               Event," means the occurrence of any of the following events or
               transactions:

          1.   The acquisition by any person other than Zions or any of its
               subsidiaries of beneficial ownership of 25% or more of the then
               outstanding shares of First Security Common Stock; or

          2.   The occurrence of an Initial Triggering Event (as defined above)
               described in paragraph (1) under the definition of "Initial
               Triggering Event" above, except that the percentage referred to
               in clause (z) of such paragraph (1) shall be 25%.

               As defined in the Option Agreement, "Exercise Termination Event"
               means any one of the following events:

          1.   The Effective Time of the Merger;

          2.   The termination of the Merger Agreement in accordance with the
               terms thereof prior to the occurrence of an Initial Triggering
               Event except a termination by Zions pursuant to Section 8.01(b)
               of the Merger Agreement (a "Listed Termination"); or

          3.   The passage of 18 months (or such longer period if extended under

               Option Agreement) after termination of the Merger Agreement if
               such termination follows the occurrence of an Initial Triggering
               Event or is a Listed Termination.

         As provided in the Option Agreement, in the event that Zions is
         entitled to and wishes to exercise the Option, it must send to First
         Security a written notice (the date of which is referred to in the
         Option Agreement as the "Notice Date") specifying (1) the total number
         of shares of First Security Common Stock which Zions intends to
         purchase pursuant to such exercise and (2) a place and date for the
         closing that shall not be less than three business days nor more than
         60 business days from the Notice Date; provided, however, that if prior
         notification to or approval of the Federal Reserve Board or any other
         regulatory authority or antitrust agency is required in connection with
         such purchase, Zions will promptly file and expeditiously process the
         required notice or application for approval.

         Under the Bank Holding Company Act of 1956 (the "BHC Act"), Zions may
         not directly or indirectly acquire more than 5% of the outstanding
         shares of any class of voting securities of First Security without
         application to and prior approval from the Federal Reserve Board.

         The Option may be assigned by Zions in certain circumstances, subject
         to the terms and conditions described in the Option Agreement.

         In addition, any shares of First Security Common Stock purchased upon
         the exercise of the Option may be resold by Zions pursuant to
         registration rights under the Option Agreement.

         A "Repurchase Event" shall be deemed to occur if: (i) a person (other
         than Zions or any Zions subsidiary) acquires (A) beneficial ownership
         of 50% or more of the then outstanding First Security Common Stock, or
         (B) beneficial ownership of 15% or more of the then outstanding First
         Security Common Stock if First Security shall have violated Section
         6.16 of the Merger Agreement; or (ii) any Acquisition Transaction (as
         defined above) is consummated. Upon occurrence of a Repurchase Event,
         (i) at the request of Zions, delivered prior to an Exercise Termination
         Event, First

         Security has agreed to repurchase the Option from Zions at a price (the
         "Option Repurchase Price") equal to (x) 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 the Option may then be
         exercised and (ii) at the request of the owner of any shares that have
         been issued upon exercise of the Option (the "Option Shares"), First
         Security has agreed to repurchase such number of the Option Shares from
         the owner thereof as the owner shall designate at a price (the "Option
         Share Repurchase Price") equal to (x) 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 First
         Security Common Stock at which a tender offer or exchange offer
         therefor has been made, (ii) the price per share of First Security
         Common Stock to be paid by any third party pursuant to an agreement
         with First Security, (iii) the highest closing price for shares of
         First Security Common Stock within the six-month period immediately
         preceding the date the holder or owner gave notice of the required
         repurchase, or (iv) in the event of a sale of all or any substantial
         part of First Security's assets or deposits, the sum of the price paid
         in such sale for such assets and the current market value of the
         remaining assets of First Security as determined by a
         nationally-recognized independent investment banking firm mutually
         selected by Zions or the owner of the Options Shares, as the case may
         be, and reasonably acceptable to First Security, divided by the number
         of shares of First Security Common Stock outstanding at the time of
         such sale.

         Zions may, at any time following a Repurchase Event and prior to the
         occurrence of an Exercise Termination Event, relinquish the Option
         (together with any Option Shares issued to and then owned by Zions) to
         First Security in exchange for a cash fee equal to $160 million (i)
         plus, if applicable, Zions' purchase price with respect to any Option
         Shares and (ii) minus, if applicable, the excess of (A) the net price,
         if any, received by Zions or a Zions 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) Zions'
         purchase price of such Option Shares.

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

         If, prior to an Exercise Termination Event, First Security enters into
         certain agreements relating to the consolidation or merger of First
         Security or the sale of substantially all of its assets or deposits,
         First Security is required to make proper provision so that the Option
         will, upon consummation of such transaction, be converted into, or
         exchanged for, an option (the "Substitute Option"), at Zions' election,
         in the Acquiring Corporation (as defined in the Option Agreement) or in
         any person that controls the Acquiring Corporation. The Substitute
         Option generally will have the same terms and conditions as the Option;
         provided, however, that to the extent terms and conditions of the
         Substitute Option cannot legally be identical to those of the Option,
         they will be as similar as possible, and in no event will be less
         advantageous to Zions.

         The Substitute Option shall be exercisable for such number of shares of
         the common stock of the Acquiring Corporation or any person that
         controls the Acquiring Corporation (the "Substitute Common Stock") as
         is equal to the market/offer price (defined in the paragraph describing
         "Repurchase Events" above) multiplied by the number of shares of Common
         Stock for which the Option was exercisable immediately prior to the
         event described in the preceding paragraph, divided by the average
         closing price of one share of Substitute Common stock for the year
         immediately prior to the event described in the preceding paragraph,
         but in no event higher than the closing price of one share of the
         Substitute Common Stock on the day immediately prior to the event in
         the preceding paragraph. The exercise price of the Substitute Option
         per share of Substitute Common Stock shall be equal to the Option Price
         multiplied by a fraction, the numerator of which shall be the number of
         shares of First Security Common Stock for which the Option was
         exercisable immediately prior to the event described in the preceding
         paragraph and the denominator of which shall be the number of shares of
         Substitute Common Stock for which the Substitute Option is exercisable.
         In no event, however, 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.

         At the request of the holder of the Substitute Option, the issuer of
         the Substitute Option shall repurchase the Substitute Option 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 of shares of
         Substitute Common Stock (the "Substitute Shares"), the Substitute
         Option Issuer shall repurchase the Substitute Shares at a 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 holder of the
         Substitute Option gives notice of the required repurchase of the
         Substitute Option or owner of the Substitute Shares gives notice of the
         required repurchase of the Substitute Shares, as applicable.

         In certain circumstances related to the exercise of the Option, the
         time periods specified in the Option Agreement will be extended (1) to
         the extent necessary to obtain all regulatory approvals (so long as
         Holder, the Substitute Option Holder, or Substitute Share Owner is
         using commercially reasonable efforts to obtain such approval) and for
         the expiration of all statutory waiting periods; (2) to the extent
         necessary to avoid liability under Section 16(b) of the Exchange Act by
         reason of such exercise; and (3) while there exists an injunction,
         order or judgment prohibiting or delaying the exercise of such right.

         Copies of the Option Agreement and the Merger Agreement are filed as
         exhibits to this Schedule 13D and are incorporated herein by reference.
         The foregoing summary is not intended to be complete and is qualified
         in its entirety by reference to such exhibits.

     C.  PURCHASES OF FIRST SECURITY COMMON STOCK.

         During the 60-day period prior to the date hereof, Zions acquired
         862,658 shares of First Security Common Stock in brokers transactions
         on the NASDAQ

         National Market. Subject to market conditions and developments with
         respect to the Merger, Zions may purchase additional shares of First
         Security Common Stock in the open market or in privately negotiated
         transactions, to the extent permitted by the BHC Act and federal
         securities laws.

         Other than as described above or in item 5 below, Zions does not have
         any plans or proposals which relate to or would result in any of the
         matters listed in item 4(a)-(j) of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

          (a)  The Option. As a result of entry into the Option Agreement and
               the granting of the Option thereunder, pursuant to Rule
               13d-3(d)(i) under the Exchange Act, Zions is deemed to own
               beneficially 38,798,410 shares of First Security Common Stock (or
               such lesser amount as shall constitute 19.9% of the outstanding
               shares of First Security Common Stock on the date of exercise),
               constituting approximately 19.9% of the shares of First Security
               Common Stock issued and outstanding as of June 8, 1999. Zions
               expressly disclaims any beneficial ownership of the 38,798,410
               shares of First Security Common Stock which are obtainable by
               Zions upon exercise of the Option because the Option is
               exercisable only in the circumstances set forth in the Option
               Agreement, which is described in Item 4 hereof, none of which has
               occurred as of the date hereof and only then with regulatory
               approval (if, as a consequence, Zions would own more than 5% of
               the outstanding shares of First Security Common Stock).

          (b)  If Zions were to exercise the Option, it would have sole power to
               vote and, subject to the terms of the Option Agreement, sole
               power to direct the disposition of, the shares of First Security
               Common Stock covered thereby.

          (c)  Not applicable.

          (d)  Not applicable.

          (e)  Not applicable.

         Item 4 above, there are no contracts, arrangements, understandings or
         relationships (legal or otherwise) between the reporting person and any
         person with respect to any securities of the Issuer.

         AGREEMENT AND PLAN OF MERGER, dated as of June 6, 1999 (this
"Agreement"), by and between Zions Bancorporation, a Utah corporation ("Zions"),
and First Security Corporation, a Delaware corporation ("First Security").

RECITALS

         A. The Proposed Transaction. This Agreement provides for a business
combination to be effected through the merger of Zions with and into First
Security (the "Merger"), with First Security as the surviving corporation (the
"Surviving Corporation"), whereby each outstanding share of common stock, no par
value per share, of Zions ("Zions Common Stock"), other than certain excluded
shares, will be converted into one share of common stock, par value $1.25 per
share, of the Surviving Corporation ("Surviving Corporation Common Stock").
Immediately prior to the effectiveness of the Merger, First Security will effect
a reverse stock split in which each outstanding share of common stock, par value
$1.25 per share, of First Security ("First Security Common Stock") will be
reclassified and converted into 0.442 of a share of Surviving Corporation Common
Stock.

         B. Board Approvals. The respective boards of directors of Zions and
First Security have each determined that the Merger and the other transactions
contemplated hereby are consistent with, and in furtherance of, their respective
business strategies and goals.

         C. Intended Tax Treatment. For federal income tax purposes, it is
intended that the Merger will be treated as a reorganization under the
provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended,
and the rules and regulations promulgated thereunder (the "Code").

         D. Intended Accounting Treatment. For financial accounting purposes, it
is intended that the Merger will be accounted for as a pooling-of-interests
transaction.

         E. Stock Option Agreements. Immediately following the due execution and
delivery of this Agreement, First Security and Zions will enter into a stock
option agreement (the "First Security Stock Option Agreement"), pursuant to
which First Security will grant Zions the option (the "First Security Option")
to purchase shares of First Security Common Stock, upon the terms and subject to
the conditions set forth therein. Simultaneously with the due execution and
delivery of this Agreement, Zions and First Security will enter into a stock
option agreement (the "Zions Stock Option Agreement" and, together with the
First Security Stock Option Agreement, the "Option Agreements"), pursuant to
which Zions will grant First Security the option (the "Zions Option") to
purchase shares of Zions Common Stock, upon the terms and subject to the
conditions set forth therein.

and the Articles of Merger are filed in the office of the Utah Division of
Corporation and Commercial Code (the "Corporation Division"), or at such
subsequent date or time as Zions and First Security shall agree and specify in
the Certificate of Merger and the Articles of Merger (the time the Merger

         2.05 Certificate of Incorporation and By-laws.

          (a) The First Security Certificate, as in effect immediately prior to

     so as to read in its entirety in the form set forth as Exhibit A-1 and, as
     so amended and restated, such certificate of


                                       -9-

     incorporation shall be the certificate of incorporation of the Surviving
     Corporation until thereafter changed or amended as provided therein or by
     applicable law.

          (b) The First Security By-laws, as in effect immediately prior to the
     Effective Time, shall be amended and restated as of the Effective Time so
     as to read in their entirety in the form set forth as Exhibit A-2 and, as

and qualified, as the case may be, it being agreed that if any director shall be
unable or unwilling to serve as a director at the Effective Time the party which
designated such individual as indicated in Exhibit B shall designate another
individual to serve in such individual's place. If any officer set forth on or
designated in accordance with Exhibit B ceases to be a full-time employee of
either First Security or Zions at or before the Effective Time or shall be

         2.07 Reverse Stock Split. First Security shall take all actions
necessary to effect the reclassification of the First Security Common Stock such
that, immediately prior to the Effective Time, each outstanding share (which
shall include for this purpose any First Security Common Stock held by First
Security as Treasury Stock) of First Security Common Stock shall be
automatically reclassified and converted into 0.442 (the "Ratio") of a validly
issued, fully paid and nonassessable share of Surviving Corporation Common Stock
(the "Reverse Stock Split") (with the resulting number of shares of each
registered holder of First Security Common Stock being rounded down to the
nearest whole number and with each such registered holder being entitled to
receive from First Security in lieu of any fractional share of Surviving
Corporation Common Stock prior to such rounding down an amount in cash (without
interest) equal to the product obtained by multiplying (x) the fraction of a
share of Surviving Corporation Common Stock to which such holder (after taking
into account all shares of First Security Common Stock held immediately prior to
the effective time of the Reverse Stock Split by such holder) would otherwise be
entitled to and (y) the last sales price per share of Zions Common Stock on
NASDAQ on the last trading day prior to the date on which the Reverse Stock
Split occurs), including arranging for the exchange of certificates representing
First Security Common Stock for certificates representing Surviving Corporation
Common Stock following the effectiveness of the Reverse Stock Split. Anything to
the contrary notwithstanding, First Security's obligation to cause the Reverse
Stock Split to become effective shall be subject to the prior satisfaction or
waiver, as applicable, of each of the conditions to the respective obligation of
each party to effect


                                      -10-



<PAGE>



the Merger set forth in Article VII (other than Section 7.01(g)) shall have been
satisfied or waived.


                                   ARTICLE III

                       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 Security Stock or Zions Common Stock:

          (a) Cancellation of Treasury Stock. Each share of Treasury Stock shall
     automatically be canceled and retired and shall cease to exist, and no
     consideration shall be delivered in exchange therefor.

          (b) Zions and First Security Common Stock and Series A Preferred
     Stock. (i) Except as set forth in Section 3.01(a), each issued and
     outstanding share of Zions Common Stock immediately prior to the Effective
     Time shall be converted into, subject to the prior effectiveness of the
     Reverse Stock Split, one fully paid and nonassessable share of Surviving
     Corporation Common Stock (the "Conversion Ratio"). As of the Effective
     Time, all shares of Zions 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 Zions Common Stock
     (other than shares to be canceled in accordance with Section 3.01(a))
     immediately prior to the Effective Time shall be deemed for all purposes to
     represent the number of shares of Surviving Corporation Common Stock into
     which they were converted pursuant to this subparagraph (b) (provided that
     if an exchange of certificates formerly representing Zions Common Stock for
     certificates representing Surviving Corporation Common Stock is required by
     law or applicable rule or regulation, the parties will cause the Surviving
     Corporation to arrange for such exchange on a one share-for-one share
     basis).

          (ii) Each share of First Security Common Stock and each share of
     Series A Preferred Stock issued and outstanding immediately prior to the
     Effective Time, assuming the prior effectiveness of the Reverse Stock
     Split, shall remain an issued and outstanding share of Surviving
     Corporation Common Stock and a share of Series A Preferred Stock of the
     Surviving Corporation, respectively.

         3.02 Rights as Stockholders; Stock Transfers. At the Effective Time,
holders of Zions Common Stock shall cease to be, and shall have no rights as,
shareholders of Zions, other than to receive any dividend or other distribution
with respect to such Zions Common Stock with a record date occurring prior to
the Effective Date and the conversion rights provided under this


                                      -11-



<PAGE>



Article III. After the Effective Time, there shall be no transfers on the stock
transfer books of Zions or the Surviving Corporation of shares of Zions Common
Stock.

         3.03 Exchange Procedures. If, pursuant to Section 3.01(b)(i), an
exchange of certificates will occur:

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

          (b) Promptly after the Effective Date, First Security shall send or
     cause to be sent to each former holder of record of shares of Zions 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. First Security 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 Zions Common Stock (or indemnity reasonably
     satisfactory to First Security 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 Zions 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 First Security Common
     Stock with a record date occurring after the Effective Date shall be paid
     in respect of any unsurrendered Old Certificate representing shares of
     Zions Common Stock converted in the Merger into the right to receive shares
     of First Security Common Stock. Upon surrender of Old Certificates (or
     indemnity reasonably satisfactory to First Security and the Exchange Agent,
     if any of such certificates are lost, stolen or destroyed) in accordance
     with this 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


                                      -12-

<PAGE>



     with respect to shares of First Security Common Stock such holder had the
     right to receive upon surrender of Old Certificates (or delivery of such
     indemnity).

         3.04 Anti-Dilution Provisions. In the event that, with the other
party's consent, Zions or First Security changes (or establishes a record date
for changing) the number or kind of shares of Zions Common Stock or First
Security Common Stock, as the case may be, 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 Zions Common Stock or First Security Common Stock, as the case may
be (other than, with respect to First Security, the Reverse Stock Split), and
the record date therefor shall be prior to the Effective Date, the ratio
contemplated by Section 3.01(b) or Section 2.07, as the case may be, shall be
proportionately adjusted in such manner as First Security and Zions shall agree,
which adjustment may include, as appropriate, the issuance of securities,
property or cash on the same basis as that on which any of the foregoing shall
have been issued, distributed or paid to the holders of Zions Common Stock or
First Security Common Stock, as the case may be, generally.

         3.05 Stock Options. (a) As soon as practicable following the date of
this Agreement, the Zions Board (or, if appropriate, any committee administering
the Zions Stock Plans) shall adopt such resolutions or take such other actions
as may be required to effect the following:

          (i) adjust the terms of all outstanding options to purchase shares of
     Zions Common Stock ("Zions Common Stock Options") granted under the Zions
     Stock Plans, whether vested or unvested, as necessary to provide that, at
     the Effective Time, each such Zions Common Stock Option outstanding
     immediately prior to the Effective Time shall be amended and converted,
     subject to the prior effectiveness of the Reverse Stock Split, into an
     option to acquire one share of Surviving Corporation Common Stock for each
     share of Zions Common Stock subject to such Zions Common Stock Option
     (each, as so adjusted, an "Adjusted Option"); and

          (ii) make such other changes to the Zions Stock Plans as First
     Security and Zions may agree are appropriate to give effect to the Merger,
     including as provided in paragraph (d) of this Section 3.05.

          (b) As soon as practicable following the date of this Agreement, the
     First Security Board (or, if appropriate, any committee administering the
     First Security Stock Plans) shall adopt such resolutions or take such other
     actions as may be required to effect the following:

          (i) all outstanding options to purchase shares of First Security
     Common Stock ("First Security Common Stock Options") granted under the
     First Security Stock Plans, whether vested or unvested, shall be adjusted
     in accordance with their terms to provide


                                      -13-

<PAGE>



     that at the effectiveness of the Reverse Stock Split (A) each such First
     Security Common Stock Option outstanding immediately prior to the
     effectiveness of the Reverse Stock Split shall be converted into an option
     to acquire a number of shares of Surviving Corporation Common Stock equal
     to the number of shares of First Security Common Stock for which such First
     Security Common Stock Option was exercisable immediately prior to the
     Reverse Stock Split multiplied by the Ratio, provided that any fractional
     shares of Surviving Corporation Common Stock resulting therefrom shall be
     rounded to the nearest whole share; and (B) the exercise price per share of
     Surviving Corporation Common Stock under a First Security Common Stock
     Option which has been adjusted in accordance with this Section 3.05(b)(i)
     shall be equal to the exercise price per share of First Security Common
     Stock under the original First Security Common Stock Option divided by the
     Ratio, provided that such exercise price shall be rounded to the nearest
     whole cent; and

          (ii) make such other changes to the First Security Stock Plans as
     First Security and Zions may agree are appropriate to give effect to the
     Merger, including as provided in paragraph (d) of this Section 3.05.

          (c) As soon as practicable after the Effective Time, the Surviving
     Corporation shall: (i) deliver to the holders of Zions Common Stock Options
     appropriate notices setting forth such holders' rights pursuant to the
     respective Zions Stock Plans and the agreements evidencing the grants of
     such Zions Common Stock Options and that such Zions Common Stock Options
     and agreements shall be assumed by the Surviving Corporation and shall
     continue in effect on the same terms and conditions (subject to the
     adjustments required by this Section 3.05 after giving effect to the
     Merger); and (ii) deliver to the holders of First Security Common Stock
     Options appropriate notices setting forth such holders' rights pursuant to
     the respective First Security Stock Plans and the agreements evidencing the
     grants of such First Security Common Stock Options and that such First
     Security Common Stock Options and agreements shall be assumed by the
     Surviving Corporation and shall continue in effect on the same terms and
     conditions (subject to the adjustments required by this Section 3.05 after
     giving effect to the Merger).

          (d) At the Effective Time, by virtue of the Merger, the Zions Stock
     Plans shall be assumed by the Surviving Corporation, with the result that
     all obligations of Zions under the Zions Stock Plans, including with
     respect to awards outstanding at the Effective Time under each Zions Stock
     Plan, shall be obligations of the Surviving Corporation following the
     Effective Time. Prior to the Effective Time, First Security shall take all
     necessary actions (including, if required, to comply with Section 162(m) of
     the Code (and the regulations thereunder) or applicable law, including
     obtaining the approval of its stockholders at the First Security Meeting)
     for the assumption of the Zions Stock Plans, including the reservation,
     issuance and listing of shares of Surviving Corporation


                                      -14-

<PAGE>



     Common Stock in a number at least equal to the number of shares of
     Surviving Corporation Common Stock that will be subject to Adjusted
     Options. No later than the Effective Time, First Security shall prepare and
     file with the SEC a registration statement on Form S-8 (or another
     appropriate form) registering a number of shares of Surviving Corporation
     Common Stock determined in accordance with the preceding sentence. Such
     registration statement shall be kept effective (and the current status of
     the prospectus or prospectuses required thereby shall be maintained) at
     least for so long as Adjusted Options or any unsettled awards granted under
     the Zions Stock Plans after the Effective Time remain outstanding.
     Following the Effective Time, the Surviving Corporation shall maintain the
     effectiveness of a registration statement on Form S-3 or Form S-8, as the
     case may be (or any successor or other appropriate forms), and shall
     maintain the current status of the prospectus or prospectuses contained
     therein, with respect to the First Security Common Stock subject to the
     First Security Common Stock Options, for so long as such First Security
     Common Stock Options remain outstanding.

          (e) At the Effective Time, each right of any kind, whether vested or
     unvested, contingent or accrued, to acquire or receive shares of Zions
     Common Stock that may be held, awarded, outstanding, credited, payable or
     reserved for issuance under the Zions Stock Plans and any other Zions
     Benefit Plan, except for Zions Common Stock Options converted in accordance
     with Section 3.05(a) above, shall be deemed to be converted into a right to
     acquire or receive, as the case may be, subject to the prior effectiveness
     of the Reverse Stock Split, the number of shares of Surviving Corporation
     Common Stock equal to the number of shares of Zions Common Stock subject to
     such right immediately prior to the Effective Time, and such rights with
     respect to the shares of Surviving Corporation Common Stock shall otherwise
     be subject to the same terms, conditions and restrictions, if any, as were
     applicable to the rights with respect to the shares of Zions Common Stock
     under the relevant Zions Stock Plan or Zions Benefit Plan. Similarly, all
     Zions Stock Plans and other Zions Benefit Plans (and awards thereunder)
     providing for benefits measured by the value of a number of shares of Zions
     Common Stock shall be deemed to refer, subject to the prior effectiveness
     of the Reverse Stock Split, to the same number of shares of Surviving
     Corporation Common Stock, and such benefits shall otherwise be paid on the
     same terms, conditions and restrictions, if any, as were applicable under
     the relevant Zions Stock Plan or Zions Benefit Plan. At or prior to the
     Effective Time, Zions shall adopt appropriate amendments to the Zions Stock
     Plans and the Zions Benefit Plans to effectuate the provisions of this
     paragraph. Without limiting the applicability of the foregoing, Zions shall
     take all necessary action to ensure that the Surviving Corporation will not
     be bound at the Effective Time by any options, stock appreciation rights,
     warrants or other rights or arrangements under any Zions Benefit Plan that
     would entitle any person to own any shares of Zions Common Stock or to
     receive any payments in respect thereof, and all Zions Benefit Plans
     conferring any rights to Zions Common Stock or other capital stock of Zions
     shall be deemed to be amended to be in conformity with this paragraph.

         5.01 Disclosure Schedules. On or prior to the date hereof, Zions has
delivered to First Security a schedule and First Security has delivered to Zions
a schedule (respectively, its "Disclosure Schedule") setting forth, among other
things, items the disclosure of which is necessary or appropriate either in
response to an express disclosure requirement contained in a provision hereof or
as an exception to one or more representations or warranties contained in
Section 5.03 or to one or more of its covenants contained in Article IV;
provided, that the mere inclusion of an item in a Disclosure Schedule as an
exception to a representation or warranty shall not be deemed an admission by a
party that such item was required to be disclosed therein.

         5.02 Standard. No representation or warranty of First Security or Zions
contained in Section 5.03 (other than the representations and warranties
contained in Section 5.03(b) and 5.03(c)) shall be deemed untrue and no party
hereto shall be deemed to have breached a representation or warranty, as a
consequence of the existence of any fact, event or circumstance unless such
fact, circumstance or event, individually or taken together with all other
facts, events or circumstances inconsistent with any representation or warranty
contained in Section 5.03 has had or is reasonably likely to have a Material
Adverse Effect with respect to First Security or Zions, as the case may be.

     2.05 hereof and (F) such filings with applicable securities exchanges to
     obtain the authorizations for listing contemplated by this Agreement.

          (ii) Subject to receipt of the regulatory approvals referred to in the

     required filings under federal and state securities laws, the execution,
     delivery and performance of this Agreement and the Option Agreements and
     the consummation of the transactions contemplated hereby and thereby 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,

     Zions Articles, as the case may be, or the First Security By-laws or the
     Zions By-laws, as the case may be, or (C) require any consent or approval
     under any such law, rule, regulation, judgment, decree, order, governmental
     permit or license, agreement, indenture or instrument.

          (h) Financial Reports and Regulatory Documents; Material Adverse
     Effect. (i) Its Annual Reports on Form 10-K for the fiscal years ended

     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

          (ii) 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.

          (iii) 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 (i) material to it and its
     Subsidiaries, taken as a whole, or (ii) 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 or
     the Option Agreements.

          (j) Regulatory Matters. (i) Neither it nor any of its Subsidiaries is
     a party to or is subject to any written order, decree, agreement,
     memorandum of understanding or similar arrangement with, or a commitment
     letter or similar submission to, or extraordinary supervisory letter from,
     any federal or state Governmental Authority charged with the supervision or
     regulation of financial 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").

          (ii) 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) is in compliance with all applicable federal, state, local and

     or decrees applicable thereto or to the employees conducting such

<PAGE>



          (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 is not in compliance with any of the statutes, regulations or
     ordinances 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 materially
     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 J.P. Morgan Securities Inc. in the case of First Security and a
     Previously Disclosed fee to be paid to Goldman, Sachs & Co. in the case of
     Zions.

          (n) Employee Benefit Plans.

     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.


                                      -25-



<PAGE>



          (ii) 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 its knowledge, 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 be reasonably likely to 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.

          (iii) 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.

          (iv) 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.

          (v) 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.

          (vi) 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.

          (vii) 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 Date, 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 Date) 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 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


                                      -27-



<PAGE>



     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. (i) (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, 1997. 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


                                      -28-



<PAGE>



     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.

          (ii) 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 (i) in accordance with prudent business practices and all
     applicable laws, rules, regulations and regulatory policies and (ii) 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 any of its obligations under any such agreement or arrangement.

          (s) Books and Records. Its books and records and those of its
     Subsidiaries have been fully, properly and accurately maintained in all
     material respects, and there are no material inaccuracies or discrepancies
     of any kind contained or reflected therein.

          (t) Insurance. It has made available to the other party hereto all of
     the 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 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. It has taken all action required to be taken by it
     in order to exempt this Agreement and the Zions Option or the First
     Security Option, as applicable, and the transactions contemplated hereby
     and thereby from, and this Agreement, the Zions Option or the First
     Security 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


                                      -29-



<PAGE>



     regulations of any state (collectively, "Takeover Laws"), including,
     without limitation, the State of Delaware in the case of First Security and
     the State of Utah in the case of Zions.

          (w) Rights Agreement. It has taken all action necessary such that the
     Zions Rights or the First Security 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.

          (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.


                                   ARTICLE VI

                                    COVENANTS

         6.01 Reasonable Best Efforts. Subject to the terms and conditions of
this Agreement, each of Zions and First Security agrees to use its respective
reasonable best efforts in good faith to take, or cause to be taken, all
actions, and to do, or cause to be done, all things necessary, proper or
desirable, or advisable under applicable laws, so as to permit consummation of
the Merger as promptly as practicable and otherwise to enable consummation of
the transactions contemplated hereby and shall cooperate fully with the other
party hereto to that end.

         6.02 Stockholder Approvals. (a) Each of Zions and First Security 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 "Zions Meeting" and
the "First Security Meeting", respectively), as promptly as practicable, to
consider and vote upon (i) the approval of the issuance of Surviving Corporation
Common Stock as contemplated by this Agreement, the Reverse Stock Split and the
amendment and restatement of the First Security Certificate contemplated by
Section 2.05, in the case of the First Security Meeting, and (ii) the approval
and adoption of this Agreement, as well as any other matters required to be
approved by such entity's stockholders for consummation of the Merger, in the
case of both the Zions Meeting and the First Security Meeting.

         (b) The boards of directors of Zions and First Security have adopted
resolutions recommending to the shareholders of Zions and the stockholders of
First Security, respectively, adoption of this Agreement and the other matters
required to be approved or adopted in order to carry out the intentions of this
Agreement. Such boards of directors shall at all times continue such
recommendations in effect without qualification and shall use, and cause Zions
and First Security, respectively, to use reasonable best efforts to obtain such
adoption (it being understood and agreed that the obligations under this
sentence shall not be altered by the commencement, proposal, disclosure or
communication of any Acquisition Proposal).

         6.03 Registration Statement and Joint Proxy Statement. (a) The parties
agree jointly to prepare a registration statement on Form S-4 or other
applicable form (the "Registration Statement") to be filed by First Security
with the SEC in connection with the issuance of Surviving Corporation Common
Stock in the Merger (including the proxy statement and prospectus and other
proxy solicitation materials of Zions and First Security constituting a part
thereof (the "Joint Proxy Statement") and all related documents). The parties
agree to cooperate, 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, First Security
and Zions agree to file the Joint Proxy Statement in preliminary form with the
SEC as promptly as reasonably practicable, and First Security agrees to file the
Registration Statement with the SEC as soon as reasonably practicable after any
SEC comments with respect to the preliminary Joint Proxy Statement are resolved.
Each of Zions and First Security agrees to use all reasonable efforts to cause
the Registration Statement to be declared effective under the Securities Act as
promptly as reasonably practicable after filing thereof. Zions also agrees to
use all reasonable efforts to obtain all necessary state securities law or "Blue
Sky" permits and approvals required to carry out the transactions contemplated
by this Agreement. Zions agrees to furnish to First Security all information
concerning Zions, its Subsidiaries, officers, directors and stockholders as may
be reasonably requested in connection with the foregoing.

         (b) Each of Zions and First Security agrees, as to itself and its
Subsidiaries, that none of the information supplied or to be supplied by it for
inclusion or incorporation by reference in


                                      -31-



<PAGE>



(i) the Registration Statement will, 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 (ii) the Joint Proxy Statement and any
amendment or supplement thereto will, at the date of mailing to stockholders and
at the time of the Zions Meeting or the First Security 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 Zions and First Security 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.

         (c) First Security agrees to advise Zions, promptly after First
Security receives notice thereof, of the time when the Registration Statement
has become effective or any supplement or amendment has been filed, of the
issuance of any stop order or the suspension of the qualification of First
Security Common Stock for offering or sale in any jurisdiction, of the
initiation or threat of any proceeding for any such purpose, or of any request
by the SEC for the amendment or supplement of the Registration Statement or for
additional information.

         6.04 Press Releases. Zions and First Security shall consult with each
other before issuing any press release with respect to the Merger or this
Agreement and shall not issue any such press release or make any such public
statement without the prior consent of the other party, which shall not be
unreasonably withheld; provided, however, that a party may, without the prior
consent of the other party (but after prior consultation, to the extent
practicable in the circumstances) issue such press release or make such public
statement as may upon the advice of outside counsel be required by law or the
rules and regulations of NASDAQ. Zions and First Security shall cooperate to
develop all public announcement materials and make appropriate management
available at presentations related to the transactions contemplated by this
Agreement as reasonably requested by the other party.

         6.05 Access; Information. (a) Each of Zions and First Security agrees
that upon reasonable notice and subject to applicable laws relating to the
exchange of information, it shall afford the other party, and the other party's
officers, employees, counsel, accountants and other authorized representatives,
such access during normal business hours throughout the period prior to the
Effective Time to the books, records (including, without limitation, tax returns
and work papers of independent auditors), properties, personnel and to such
other information as any party may reasonably request and, during such period,
it shall furnish promptly to such other party (i) a copy of each material
report, schedule and other document filed by it pursuant to the


                                      -32-



<PAGE>



requirements of federal or state securities or banking laws, and (ii) all other
information concerning the business, properties and personnel of it as the other
may reasonably request.

         (b) Each party agrees that it will not, and will cause its
representatives not to, use any information obtained pursuant to this Section
6.05 (as well as any other information obtained prior to the date hereof in
connection with the entering into of this Agreement) for any purpose unrelated
to the consummation of the transactions contemplated by this Agreement. Subject
to the requirements of law, each party will keep confidential, and will cause
its representatives to keep confidential, all information and documents obtained
pursuant to this Section 6.05 (as well as any other information obtained prior
to the date hereof in connection with the entering into of this Agreement)
unless such information (i) was already known to such party, (ii) becomes
available to such party from other sources not known by such party to be bound
by a confidentiality obligation, (iii) is disclosed with the prior written
approval of the providing party or (iv) is or becomes readily ascertainable from
publicly available sources. In the event that this Agreement is terminated or
the transactions contemplated by this Agreement shall otherwise fail to be
consummated, each party shall promptly cause all copies of documents or extracts
thereof containing information and data as to the other party to be returned to
the other party.

         (c) No investigation by either party of the business and affairs of the
other party, pursuant to this Section 6.05 or otherwise, shall affect or be
deemed to modify or waive any representation, warranty, covenant or agreement in
this Agreement, or the conditions to either party's obligation to consummate the
transactions contemplated by this Agreement.

         6.06 Acquisition Proposals. Each of Zions and First Security agrees
that it shall not, and shall cause its Subsidiaries and its and its
Subsidiaries' officers, directors, agents, advisors and affiliates not to,
solicit or encourage inquiries or proposals with respect to, or engage in any
negotiations 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 Zions Rights Agreement or the First
Security Current Rights Agreement or the First Security Replacement Rights
Agreement, respectively, in respect of an Acquisition Proposal. Each of Zions
and First Security shall immediately cease and cause to be terminated any
activities, discussions or negotiations conducted prior to the date of this
Agreement with any Persons other than First Security or Zions, as the case may
be, with respect to any of the foregoing and shall use its reasonable best
efforts to enforce any confidentiality or similar agreement relating to an
Acquisition Proposal. Each of Zions and First Security shall promptly (within 24
hours) advise the other party following the receipt by Zions or First Security,
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 apprized of any developments in respect thereof on a
constant basis.

         6.07 Affiliate Agreements. (a) Not later than the 15th day prior to the
mailing of the Joint Proxy Statement, (i) Zions shall deliver to First Security
a schedule of each Person that, to


                                      -33-

the best of its knowledge, is or is reasonably likely to be, as of the date of
the Zions Meeting, deemed to be an "affiliate" of Zions (each, a "Zions

and (ii) First Security shall deliver to Zions a schedule of each Person that,
to the best of its knowledge, is or is reasonably likely to be, as of the date
of the First Security Meeting, deemed to be an "affiliate" of First Security
(each, an "First Security Affiliate") as that term is used in Rule 145 under the
Securities Act or SEC Accounting Series Releases 130 and 135.

         (b) Each of Zions and First Security shall use its respective
reasonable best efforts to cause each Person who may be deemed to be a Zions
Affiliate or a First Security Affiliate to execute and deliver to Zions and
First Security on or before the date of mailing of the Joint Proxy Statement an
agreement in substantially the form attached hereto as Exhibit C or Exhibit D,
respectively.

         6.08 Takeover Laws. No party hereto shall take any action that would
cause the transactions contemplated by this Agreement or the Option Agreements
to be subject to requirements imposed by any Takeover Law, and each of them
shall take all necessary steps within its control to exempt (or ensure the
continued exemption of) the transactions contemplated by this Agreement from, or
if necessary challenge the validity or applicability of, any applicable Takeover
Law, as now or hereafter in effect.

         6.09 NASDAQ. First Security shall use commercially reasonable efforts
to cause the Surviving Corporation Common Stock to be issued in the Merger to be
approved for quotation on the NASDAQ, subject to official notice of issuance, as
promptly as practicable after the date hereof, and in any event prior to the
Effective Date.

         6.10 Regulatory Applications. (a) Zions and First Security and their
respective Subsidiaries shall cooperate and use their respective reasonable best
efforts to prepare as promptly as possible all documentation, to effect all
filings and to obtain all permits, consents, approvals and authorizations of all
third parties and Governmental Authorities necessary to consummate the
transactions contemplated by this Agreement and First Security shall make all
necessary regulatory filings as soon as practicable. Each of Zions and First
Security shall have the right to review in advance, and to the extent
practicable each will consult with the other, in each case subject to applicable
laws relating to the exchange of information, with respect to all material
written information submitted to any third party or any Governmental Authority
in connection with the transactions contemplated by this Agreement. In
exercising the foregoing right, each of the parties hereto agrees to act
reasonably and as promptly as practicable. Each party hereto agrees that it will
consult with the other party hereto with respect to the obtaining of all
material permits, consents, approvals and authorizations of all third parties
and Governmental Authorities necessary or advisable to consummate the
transactions contemplated by this Agreement and each party will keep the other
party appraised of the status of material matters relating to completion of the

                                      -34-



<PAGE>



         (b) Each party agrees, upon request, to furnish the other party with
all information concerning itself, its Subsidiaries, directors, officers and
stockholders and such other matters as may be reasonably necessary or advisable
in connection with any filing, notice or application made by or on behalf of
such other party or any of its Subsidiaries with or to any third party or
Governmental Authority.

         6.11 Indemnification. (a) Following the Effective Date, the Surviving
Corporation shall indemnify, defend and hold harmless the present and former
directors and officers of Zions, First Security and their respective
Subsidiaries (each, an "Indemnified Party") against all costs or expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages or liabilities (collectively, "Costs") as incurred, in connection with
any claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of actions or omissions occurring
at or prior to the Effective Time (including, without limitation, the
transactions contemplated by this Agreement) to the fullest extent that Zions,
First Security and their respective Subsidiaries are permitted to indemnify (and
advance expenses to) their respective directors and officers under the laws of
their respective jurisdictions of incorporation, their respective charters and
their respective by-laws.

         (b) For a period of six years from the Effective Time, the Surviving
Corporation shall use its reasonable best efforts to provide director's and
officer's liability insurance that serves to reimburse the present and former
officers and directors of Zions, First Security or any of their respective
Subsidiaries (determined as of the Effective Time) 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 advantageous, as
that coverage currently provided by Zions or First Security, as the case may be.

         (c) Any Indemnified Party wishing to claim indemnification under
Section 6.11(a), upon learning of any claim, action, suit, proceeding or
investigation described above, shall promptly notify the Surviving Corporation
thereof; provided that the failure so to notify shall not affect the obligations
of the Surviving Corporation under Section 6.11(a) unless and to the extent that
the Surviving Corporation is actually and materially prejudiced as a result of
such failure.

         (d) If the Surviving Corporation or any of its successors or assigns
shall consolidate with or merge into any other entity and shall not be the
continuing or surviving entity of such consolidation or merger or shall transfer
all or substantially all of its assets to any other entity, then and in each
case, the Surviving Corporation shall cause proper provision to be made so that

be prejudicial to the interests of the stockholders of either party. This

                             STOCK OPTION AGREEMENT

    STOCK OPTION AGREEMENT, dated as of June 8, 1999, between Zions
Bancorporation, a Utah corporation ("Grantee"), and First Security Corporation,
a Delaware corporation ("Issuer").

                                    RECITALS

        A. Merger Agreement. Grantee and Issuer have entered into an Agreement
and Plan of Merger, dated as of June 6, 1999 (the "Merger Agreement"), which
agreement has been executed by the parties hereto immediately prior to this
Stock Option Agreement; and

        B. Option. As a condition to Grantee's entering into the Merger
Agreement and in consideration therefor and in consideration for the option
granted to Issuer by Grantee pursuant to an option agreement dated as of the
date hereof, 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
38,798,410 fully paid and nonassessable shares of the common stock, par value
$1.25 per share, of Issuer ("Common Stock") at a price per share equal to the
average of the last reported sale prices per share of Common Stock as reported
on the NASDAQ National Market (as reported in The Wall Street Journal or, if not
reported therein, in another authoritative source) on June 4, 1999 and June 7,
1999; 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 the
second sentence of Section 5 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.



<PAGE>



    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 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 (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. Anything to the contrary notwithstanding,
at no point may the Option be exercised, as a whole or in part, to the extent
that such exercise (or the acquisition of Option Shares thereunder) would, if it
occurred on the date hereof, be inconsistent with any provision of the Merger
Agreement.

    (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


                                       -2-



<PAGE>



    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);

        (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
    shareholders of Issuer approve the transactions contemplated by the Merger
    Agreement, 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 shareholders 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 in anticipation of an Acquisition
    Transaction, and 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); 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.

<PAGE>



    (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

        (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.


                                       -4-



<PAGE>



    (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 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)


                                       -5-

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 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 second
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 twelve (12) 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 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


                                       -7-



<PAGE>



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 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.



                                       -8-



<PAGE>



    (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, 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 Agreement, 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 15% more of the then
    outstanding Common Stock if Issuer shall have violated Section 6.16 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


                                       -9-



<PAGE>



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 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


                                      -10-



<PAGE>



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 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


                                      -11-

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 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


                                      -12-



<PAGE>



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 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


                                      -13-



<PAGE>



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 $160 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.

<PAGE>



    (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 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


                                      -15-



<PAGE>



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, without regard to the conflict of law principles
thereof (except to the extent that mandatory provisions of federal law are
applicable).

    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.
