             1.1  The Merger.  Subject to the terms and conditions of this
   Agreement and the Plan of Merger, a copy of which is attached hereto as
   Exhibit C (the "Plan of Merger"), in accordance with the Wisconsin
   Business Corporation Law (the "WBCL"), at the Effective Time (as defined
   in Section 1.2), OSB shall merge with and into FCB, and FCB shall survive
   the Merger and shall continue its corporate existence under the laws of
   the State of Wisconsin.  Upon consummation of the Merger, the separate
   corporate existence of OSB shall terminate and the name of the Surviving
   Corporation shall be "FCB Financial Corp."

             The parties agree that OSB and FCB will execute a Plan of Merger
   substantially in the form attached hereto as Exhibit C which provides for
   the terms of the Merger and the mode of carrying same into effect.

             1.2  Effective Time.  The Merger shall become effective upon the
   later of (a) the time of filing of Articles of Merger with the Department
   of Financial Institutions of the State of Wisconsin (the "Wisconsin
   Department") and (b) the effective date and time of the Merger as set
   forth in such Articles of Merger.  The parties shall each use reasonable
   efforts to cause Articles of Merger to be filed on the Closing Date (as
   defined in Section 1.12).  The term "Effective Time" shall be the date and
   time when the Merger becomes effective, in accordance with this Section
   1.2.

             1.3  Effects of the Merger.  At and after the Effective Time,
   the Merger shall have the effects set forth in Section 180.1106 of the
   WBCL.

             1.4  Conversion of OSB Common Stock; Treatment of FCB Common
   Stock.

                  (a)  At the Effective Time, subject to Section 2.2, by
        virtue of the Merger and without any action on the part of OSB, or
        the holder of any securities of OSB, each share of the common stock,
        $.01 par value, of OSB (the "OSB Common Stock") issued and
        outstanding immediately prior to the Effective Time (other than
        shares canceled pursuant to Section 1.4(c)) shall be converted into
        the right to receive 1.46 shares (the "OSB Exchange Ratio") of the
        common stock, par value $.01 per share, of FCB (the "FCB Common
        Stock").

                  (b)  All of the shares of OSB Common Stock converted into
        FCB Common Stock pursuant to this Article I shall no longer be
        outstanding and shall automatically be canceled and shall cease to
        exist as of the Effective Time, and each certificate (each an "OSB
        Common Stock Certificate") previously representing any such shares of
        OSB Common Stock shall thereafter represent only the right to receive
        (i) a certificate representing the number of whole shares of FCB
        Common Stock (each a "FCB Common Stock Certificate") and (ii) cash in
        lieu of fractional shares into which the shares of OSB Common Stock
        previously represented by such OSB Common Stock Certificate have been
        converted pursuant to this Section 1.4, Section 2.2 and the Plan of
        Merger.  OSB Common Stock Certificates previously representing shares
        of OSB Common Stock shall be exchanged for FCB Common Stock
        Certificates representing whole shares of FCB Common Stock and cash
        in lieu of fractional shares issued in consideration therefor upon
        the surrender of such OSB Common Stock Certificates in accordance
        with Section 2.2, without any interest thereon.

                  (c)  At the Effective Time, all shares of OSB Common Stock
        that are owned by OSB as treasury stock, owned by the OSB MRP (as
        defined herein) and not allocated to participants thereunder or owned
        by FCB, if any, shall be canceled and shall cease to exist, and no
        stock of FCB or other consideration shall be delivered in exchange
        therefor.

                  (d)  At and after the Effective Time, each share of FCB
        Common Stock issued and outstanding immediately prior to the
        Effective Time shall remain an issued and outstanding share of common
        stock of the Surviving Corporation and shall not be affected by the
        Merger.

             1.5  Stock Options.

                  (a)  At the Effective Time, each option granted by OSB
        under the terms of the OSB Financial Corp. 1992 Stock Option and
        Incentive Plan (the "OSB Option Plan") to purchase shares of OSB
        Common Stock which is outstanding and unexercised immediately prior
        thereto shall cease to represent a right to acquire shares of OSB
        Common Stock and shall be converted automatically into an option to
        purchase shares of FCB Common Stock in an amount and at an exercise
        price determined pursuant to paragraph (c) of this Section 1.5 (the
        "Converted Option"), subject to the terms of the OSB Option Plan and
        the agreements evidencing grants of such options thereunder.

                  (b)  From and after the Effective Time, FCB shall assume
        any and all obligations of OSB under the OSB Option Plan, and the OSB
        Option Plan shall remain in effect.

                  (c)  (i) The number of shares of FCB Common Stock to be
        subject to each Converted Option shall be equal to the product of the
        number of shares of OSB Common Stock subject to the original option
        and the OSB Exchange Ratio, provided that any fractional shares of
        FCB Common Stock resulting from such multiplication shall be rounded
        up to the nearest whole share; and (ii) the exercise price per share
        of FCB Common Stock under the Converted Option shall be equal to the
        exercise price per share of OSB Common Stock under the original
        option divided by the OSB Exchange Ratio, provided that such exercise
        price shall be rounded down to the nearest whole cent.

                  (d)  The Committee of the OSB Board of Directors which
        administers the OSB Option Plan has approved the foregoing
        adjustments pursuant to Section 12(c) of the OSB Option Plan and has
        not and will not authorize cash payments to be made for options under
        the OSB Option Plan pursuant to Section 12(b) thereof.

                  (e)  Promptly after the execution of this Agreement, OSB
        shall take such action, which shall be reasonably satisfactory to
        FCB, as OSB may deem necessary in order that each Converted Option
        shall be, at the Effective Time, assumed by FCB and shall from and
        after the Effective Time no longer entitle the holder thereof to
        purchase shares of OSB Common Stock but shall be converted into and
        shall become by virtue of the Merger, automatically and without any
        action on the part of the holder thereof, a stock option to purchase
        such number of shares of FCB Common Stock at such exercise price as
        determined pursuant to paragraph (c) of this Section 1.5.

             1.6  Articles of Incorporation.  The Articles of Incorporation
   of FCB in effect as of the Effective Time shall be the Articles of
   Incorporation of the Surviving Corporation after the Merger until
   thereafter amended in accordance with applicable law.

             1.7  By-Laws.  The By-Laws of FCB in effect as of the Effective
   Time, shall be the By-Laws of the Surviving Corporation after the Merger
   until thereafter amended in accordance with applicable law.

             1.8  Tax Consequences.  It is intended that the Merger shall
   constitute a reorganization within the meaning of Section 368(a)(1)(A) of
   the Internal Revenue Code of 1986, as amended (the "Code"), and that this
   Agreement and the Plan of Merger shall constitute a "plan of
   reorganization" for the purposes of Section 368 of the Code.

             1.9  Plans for Management Succession.  At the Effective Time,
   pursuant to the terms hereof and the employment agreements referred to in
   Section 7.1(f), (a) Donald D. Parker shall be the Chairman of the Board of
   the Surviving Corporation and the Surviving Bank, (b) James J. Rothenbach
   shall be the President and Chief Executive Officer of the Surviving
   Corporation and the Surviving Bank, and (c) Phillip J. Schoofs shall be
   the Vice President, Treasurer and Chief Financial Officer of the Surviving
   Corporation and the Surviving Bank.  Nothing in this Section 1.9 shall
   preclude the Board of Directors of the Surviving Corporation or the
   Surviving Bank from subsequently removing any person appointed as an
   officer of the Surviving Corporation or the Surviving Bank pursuant to
   this Section 1.9.

             1.10 Board of Directors of the Surviving Corporation. 

                  (a)  From and after the Effective Time, the Board of
        Directors of the Surviving Corporation shall consist of fourteen (14)
        persons, including Donald D. Parker and James J. Rothenbach.  Six (6)
        directors, in addition to Donald D. Parker, shall have been selected
        by FCB ("FCB Representatives"), and six (6) directors, in addition to
        James J. Rothenbach, shall have been selected by OSB (the "OSB
        Representatives").  The FCB Representatives and the OSB
        Representatives, respectively, shall be divided as equally as
        practicable among the three classes of directors of the Surviving
        Corporation in accordance with Exhibit D, and shall serve in such
        capacities until their successors shall have been elected or
        appointed and shall have qualified in accordance with the Articles of
        Incorporation and By-laws of the Surviving Corporation and the WBCL. 
        Directors chosen from among the FCB Representatives and the OSB
        Representatives shall be equally represented on the personnel
        committee (which shall have four members) and the executive
        committee, if any, of the Board of Directors of the Surviving
        Corporation.

                  (b)  Prior to the third annual meeting of the shareholders
        of the Surviving Corporation following the Effective Time, the OSB
        Representatives and the FCB Representatives, respectively, shall have
        the right to designate (i) the person or persons to be nominated in
        place of each of the OSB Representatives and FCB Representatives,
        respectively, whose terms of office expire at each of the first three
        annual meetings of the shareholders of the Surviving Corporation
        following the Effective Time, and (ii) the person or persons to serve
        on the executive committee, if any, in place of any OSB
        Representatives or FCB Representatives, respectively, previously
        appointed to the executive committee.  For purposes of this Section
        1.10(b), the terms "OSB Representatives" and "FCB Representatives"
        shall include any person or persons subsequently appointed or elected
        directors of the Surviving Corporation following their designation as
        nominees for director by the OSB Representatives or FCB
        Representatives, respectively, in accordance with the preceding
        sentence.

                  (c)  It is the intention of OSB and FCB that the number of
        directors of the Surviving Corporation shall be reduced to ten (10)
        through attrition. To that end and until the Board of Directors shall
        consist of ten (10) directors (composed of five (5) OSB
        Representatives and five (5) FCB Representatives) any vacancy
        occurring on the Board of Directors of the Surviving Corporation
        created by the death, resignation or removal of any director will not
        be filled and, instead, within 30 days thereof, an additional vacancy
        shall be created by the voluntary resignation of an FCB
        Representative or OSB Representative, as the case may be, in order
        that the number of OSB Representatives and FCB Representatives on the
        Board of Directors of the Surviving Corporation shall remain equal,
        and thereafter, the two vacancies shall be eliminated by resolution
        of the Board of Directors of the Surviving Corporation, provided,
        however, that if an FCB Representative or OSB Representative, as the
        case may be, does not resign within this 30 day period, the OSB
        Representatives or the FCB Representatives, as the case may be, shall
        have the right to designate the person or persons to fill such
        vacancy in order that the number of OSB Representatives and FCB
        Representatives shall remain equal.   The parties hereto agree that
        the terms of this Section 1.10(c) shall bind the Board of Directors
        of the Surviving Company for three years after the Closing Date.

             1.11 Headquarters of the Surviving Corporation.   At the
   Effective Time, the headquarters and principal executive offices of the
   Surviving Corporation shall be at 420 South Koeller Street, Oshkosh,
   Wisconsin.  At the Effective Time, the commercial loan department of the
   Surviving Bank shall be located at 110 Fox River Drive, Appleton,
   Wisconsin.

             1.12 Closing.  Subject to the terms and conditions of this
   Agreement and the Plan of Merger, including but not limited to the
   provisions of Article VII of this Agreement, the closing of the Merger
   (the "Closing") will take place at 10:00 a.m. on a date and at a place to
   be specified by the parties, which shall be no later than the first
   business day in the calendar month immediately following the month in
   which the last of the conditions precedent to the Merger set forth in
   Article VII hereof is satisfied or waived, or at such other time, date and
   place as OSB and FCB shall mutually agree (the "Closing Date").

                                   ARTICLE II
                              CONVERSION OF SHARES

             2.1  FCB to Make Shares Available.  At or prior to the Effective
   Time, FCB shall deposit, or shall cause to be deposited, with a bank,
   trust company or other entity reasonably acceptable to OSB (the "Exchange
   Agent"), for the benefit of the holders of OSB Common Stock Certificates,
   for exchange in accordance with this Article II, FCB Common Stock
   Certificates and cash in lieu of any fractional shares of FCB Common Stock
   (such cash and FCB Common Stock Certificates, together with any dividends
   or distributions with respect thereto paid after the Effective Time, being
   hereinafter referred to as the "Conversion Fund") to be issued pursuant to
   Section 1.4 and paid pursuant to Section 2.2(a) in exchange for
   outstanding shares of OSB Common Stock.

             2.2  Exchange of Certificates.

                  (a)  As soon as practicable after the Effective Time, and
        in no event later than ten (10)  business days thereafter, the
        Surviving Corporation shall cause the Exchange Agent to mail to each
        holder of record of one or more OSB Common Stock Certificates a
        letter of transmittal (which shall specify that delivery shall be
        effected, and risk of loss and title to the OSB Common Stock
        Certificates shall pass, only upon delivery of the OSB Common Stock
        Certificates to the Exchange Agent) and instructions for use in
        effecting the surrender of the OSB Common Stock Certificates in
        exchange for FCB Common Stock Certificates and any cash in lieu of
        fractional shares into which the shares of OSB Common Stock
        represented by such OSB Common Stock Certificate or Certificates
        shall have been converted pursuant to this Agreement and the Plan of
        Merger.  Upon proper surrender of an OSB Common Stock Certificate for
        exchange and cancellation to the Exchange Agent, together with such
        properly completed letter of transmittal, duly executed, the holder
        of such OSB Common Stock Certificate shall be entitled to receive in
        exchange therefor, as applicable, (i) a FCB Common Stock Certificate
        representing that number of whole shares of FCB Common Stock to which
        such holder of OSB Common Stock shall have become entitled pursuant
        to the provisions of Section 1.4 hereof, and (ii) a check
        representing the amount of any cash in lieu of fractional shares that
        such holder has the right to receive in respect of such OSB Common
        Stock Certificate, and the OSB Common Stock Certificate so
        surrendered shall forthwith be canceled.  No interest will be paid or
        accrued on any cash in lieu of fractional shares payable to holders
        of OSB Common Stock Certificates.

                  (b)  If any FCB Common Stock Certificate is to be issued in
        a name other than that in which the OSB Common Stock Certificate
        surrendered in exchange therefor is registered, it shall be a
        condition of the issuance thereof that the OSB Common Stock
        Certificate so surrendered shall be properly endorsed (or accompanied
        by an appropriate instrument of transfer) and otherwise in proper
        form for transfer, and that the person requesting such exchange shall
        pay to the Exchange Agent in advance any transfer or other taxes
        required by reason of the issuance of an FCB Common Stock Certificate 
        in any name other than that of the registered holder of the OSB
        Common Stock Certificate surrendered, or required for any other
        reason, or shall establish to the satisfaction of the Exchange Agent
        that such tax has been paid or is not payable.

                  (c)  After the Effective Time, there shall be no transfers
        on the stock transfer books of OSB of the shares of OSB Common Stock
        which were issued and outstanding immediately prior to the Effective
        Time.  If, after the Effective Time, OSB Common Stock Certificates
        are presented for transfer to the Exchange Agent, they shall be
        canceled and exchanged for FCB Common Stock Certificates representing
        shares of FCB Common Stock as provided in this Article II.

                  (d)  Notwithstanding anything to the contrary contained
        herein, no certificates or scrip representing fractional shares of
        FCB Common Stock shall be issued upon the surrender for exchange of
        OSB Common Stock Certificates, no dividend or distribution with
        respect to FCB Common Stock shall be payable on or with respect to
        any fractional share, and such fractional share interests shall not
        entitle the owner thereof to vote or to any other rights of a
        shareholder of the Surviving Corporation.  In lieu of the issuance of
        any such fractional share, the Surviving Corporation shall pay to
        each former shareholder of OSB who otherwise would be entitled to
        receive such fractional share an amount in cash determined by
        multiplying (i) the average of the last sales price for FCB Common
        Stock as reported on The Nasdaq Stock Market for the twenty (20)
        trading days immediately preceding the fifth trading day prior to the
        Closing Date by (ii) the fraction of a share (rounded to the nearest
        tenth when expressed as an Arabic number) of FCB Common Stock to
        which such holder would otherwise be entitled to receive pursuant to
        Section 1.4. 

                  (e)  Any portion of the Conversion Fund that remains
        unclaimed by the shareholders of OSB for twelve (12) months after the
        Effective Time shall be paid to the Surviving Corporation.  Any
        shareholders of OSB who have not theretofore complied with this
        Article II shall thereafter look only to the Surviving Corporation
        for the issuance of certificates representing shares of FCB Common
        Stock and the payment of cash in lieu of any fractional shares and
        any unpaid dividends and distributions on the FCB Common Stock
        deliverable in respect of each share of OSB Common Stock such
        shareholder holds as determined pursuant to this Agreement and the
        Plan of Merger, in each case, without any interest thereon. 
        Notwithstanding the foregoing, none of FCB, OSB, the Exchange Agent
        or any other person shall be liable to any former holder of shares of
        OSB Common Stock, for any amount delivered in good faith to a public
        official pursuant to applicable abandoned property, escheat or
        similar laws.

                  (f)  In the event any OSB Common Stock Certificate shall
        have been lost, stolen or destroyed, upon the making of an affidavit
        of that fact by the person claiming such OSB Common Stock Certificate
        to be lost, stolen or destroyed and, if reasonably required by the
        Surviving Corporation, the posting by such person of a bond in such
        amount as the Exchange Agent may determine is reasonably necessary as
        indemnity against any claim that may be made against it with respect
        to such OSB Common Stock Certificate, the Exchange Agent will issue
        in exchange for such lost, stolen or destroyed OSB Common Stock
        Certificate an FCB Common Stock Certificate representing the shares
        of FCB Common Stock and any cash in lieu of fractional shares
        deliverable in respect thereof pursuant to this Agreement and the
        Plan of Merger.

                                   ARTICLE III
                      REPRESENTATIONS AND WARRANTIES OF OSB

             OSB hereby represents and warrants to FCB as follows:

             3.1  Corporate Organization.

                  (a)  OSB is a corporation duly organized and validly
        existing under the laws of the State of Wisconsin.  OSB has the
        corporate power and authority to own or lease all of its properties
        and assets and to carry on its business as it is now being conducted,
        and is duly licensed or qualified to do business in each jurisdiction
        in which the nature of the business conducted by it or the character
        or location of the properties and assets owned or leased by it makes
        such licensing or qualification necessary, except where the failure
        to be so licensed or qualified would not have a Material Adverse
        Effect (as defined below) on OSB.  OSB is duly registered as a
        savings and loan holding company under the Home Owners' Loan Act
        ("HOLA").  True and complete copies of the Articles of Incorporation
        and By-Laws of OSB, as in effect as of the date of this Agreement,
        have previously been made available by OSB to FCB.  As used in this
        Agreement, the term "Material Adverse Effect" means, with respect to
        OSB or FCB, as the case may be, a material adverse effect (i) on the
        business, assets, properties, results of operations, financial
        condition, or (insofar as they can reasonably be foreseen) prospects
        of such party and its Subsidiaries, taken as a whole or (ii) on the
        consummation of the Merger; provided, however, that in no event shall
        the one-time-Savings-Association-Insurance-Fund special assessment
        previously imposed by the Federal Deposit Insurance Corporation be
        deemed to constitute a Material Adverse Effect on either OSB or FCB. 
        The word "Subsidiary" when used with respect to any party means any
        bank, corporation, partnership, limited liability company, or other
        organization, whether incorporated or unincorporated, which is
        consolidated with such party for financial reporting purposes.

                  (b)  As of the date of this Agreement, OSB has, as its sole
        direct or indirect Subsidiaries, Oshkosh Savings Bank, FSB ("OSB
        Bank"), a federally-chartered savings association, Oshkosh Financial,
        Inc., RWFV, Inc. and OSB Investments, Inc. (collectively, the "OSB
        Subsidiaries").  Except as set forth on Schedule 3.1(b) of the
        disclosure schedules to this Agreement prepared and delivered by OSB
        (the "OSB Disclosure Schedules"), OSB does not own  any voting stock
        or equity securities of any bank, corporation, partnership, limited
        liability company, or other organization, whether incorporated or
        unincorporated, other than the OSB Subsidiaries.

                  (c)  Except as set forth in Schedule 3.1(c), each OSB
        Subsidiary (i) is duly organized and validly existing as a
        corporation under the laws of its jurisdiction of organization, (ii)
        is duly qualified to do business and in good standing in all
        jurisdictions (whether federal, state, local or foreign) where its
        ownership or leasing of property or the conduct of its business
        requires it to be so qualified and in which the failure to be so
        qualified would have a Material Adverse Effect on OSB, and (iii) has
        all requisite corporate power and authority to own or lease its
        properties and assets and to carry on its business as now conducted. 
        Except as set forth in Schedule 3.1(c) of the OSB Disclosure
        Schedules, none of the OSB Subsidiaries owns any voting stock or
        equity securities of any bank, corporation, partnership, limited
        liability company, or other organization, whether incorporated or
        unincorporated.

                  (d)  The minute books of OSB and of each of the OSB
        Subsidiaries have been made available to FCB and accurately reflect
        in all material respects all corporate meetings held or actions taken
        since January 1, 1992 by the shareholders and Boards of Directors of
        OSB and each OSB Subsidiary, respectively (including committees of
        the Boards of Directors of OSB and the OSB Subsidiaries).

             3.2  Capitalization.

                  (a)  The authorized capital stock of OSB consists of
        7,000,000 shares of OSB Common Stock, $0.01 par value per share, of
        which, as of September 30, 1996, 1,111,484 shares were issued and
        outstanding (which number excludes 48,650 shares of OSB Common Stock
        held by the OSB MRP (as hereinafter defined) which have not been
        awarded to participants thereunder) and 1,000,000 shares of Preferred
        Stock, $0.01 par value per share, of which, as of September 30, 1996,
        none were issued and outstanding.  As of September 30, 1996, 369,866
        shares of OSB Common Stock were held in treasury.  All of the issued
        and outstanding shares of OSB Common Stock have been duly authorized
        and validly issued and are fully paid, nonassessable (except as
        otherwise provided by Section 180.0622(2)(b) of the WBCL) and free of
        preemptive rights.  Except for the OSB Option Agreement and as set
        forth on Schedule 3.2(a) of the OSB Disclosure Schedules, OSB does
        not have and is not bound by any outstanding subscriptions, options,
        warrants, calls, commitments or agreements of any character calling
        for the purchase or issuance of any shares of OSB Common Stock or any
        other equity securities of OSB or any securities representing the
        right to purchase or otherwise receive any shares of the capital
        stock of OSB.  No shares of OSB Common Stock have been reserved for
        issuance, other than the shares of OSB Common Stock reserved for
        issuance under the OSB Option Agreement and OSB Option Plan.  Since
        September 30, 1996, OSB has not issued any shares of its capital
        stock or any securities convertible into or exercisable for any
        shares of its capital stock except upon exercise of stock options
        pursuant to the OSB Option Plan outstanding as of September 30, 1996
        and except with respect to the OSB Stock Option Agreement.

                  (b)  OSB owns, directly or indirectly, all of the issued
        and outstanding shares of capital stock of each of the OSB
        Subsidiaries, free and clear of any liens, pledges, charges,
        encumbrances and security interests whatsoever ("Liens").  All of the
        shares of capital stock of each OSB Subsidiary are duly authorized
        and validly issued and are fully paid, nonassessable (except as
        otherwise provided by Section 180.0622(2)(b) of the WBCL) and free of
        preemptive rights.  No OSB Subsidiary has or is bound by any
        outstanding subscriptions, options, warrants, calls, commitments or
        agreements of any character calling for the purchase or issuance of
        any shares of capital stock or any other equity security of such OSB
        Subsidiary or any securities representing the right to purchase or
        otherwise receive any shares of capital stock or any other equity
        security of such OSB Subsidiary.

             3.3  Authority; No Violation.  OSB has full corporate power and
   authority to execute and deliver each of this Agreement, the Plan of
   Merger and the Option Agreements and, subject to shareholder and
   regulatory approvals, to consummate the transactions contemplated hereby
   and thereby.  The execution and delivery of this Agreement, the Plan of
   Merger and the Option Agreements and the consummation of the transactions
   contemplated hereby and thereby have been duly and validly approved by the
   Board of Directors of OSB.  The Board of Directors of OSB has directed
   that this Agreement and the Plan of Merger and the transactions
   contemplated hereby and thereby be submitted to OSB's shareholders for
   approval at a meeting of such shareholders and, except for the adoption of
   this Agreement and the Plan of Merger by the affirmative vote of the
   holders of a majority of the outstanding shares of OSB Common Stock, no
   other corporate proceedings on the part of OSB are necessary to approve
   this Agreement, the Plan of Merger and the Option Agreements and to
   consummate the transactions contemplated hereby and thereby.  This
   Agreement and the Option Agreements have been duly and validly executed
   and delivered by OSB and (assuming due authorization, execution and
   delivery by FCB) constitute valid and binding obligations of OSB,
   enforceable against OSB in accordance with their respective terms. 
   Furthermore, the Plan of Merger, when executed and delivered by OSB and
   (assuming due authorization, execution and delivery by FCB), shall
   constitute a valid and binding obligation of OSB, enforceable against OSB
   in accordance with its terms.

             3.4  Consents and Approvals.  No consents or approvals of or
   filings or registrations with any court, administrative agency or
   commission or other governmental authority or instrumentality (each a
   "Governmental Entity") or with any third party are necessary in connection
   with the execution and delivery by OSB of this Agreement, the Plan of
   Merger and the Option Agreements and the consummation by OSB of the Merger
   and the other transactions contemplated hereby and thereby except for (a)
   the filing by FCB and FCB Bank of an application with the Office of Thrift
   Supervision (the "OTS") under HOLA and the approval of such application
   (the "OTS Application"), (b) the filing with the Securities and Exchange
   Commission (the "SEC") of a joint proxy statement in definitive form
   relating to the meetings of OSB's and FCB's shareholders to be held in
   connection with this Agreement and the Plan of Merger and the transactions
   contemplated hereby and thereby (the "Joint Proxy Statement") and the
   registration statement on Form S-4 (the "S-4") in which such Joint Proxy
   Statement will be included as a prospectus, (c) the filing of Articles of
   Merger with the Wisconsin Department under the WBCL, (d) such filings and
   approvals as are required to be made or obtained under the securities or
   "Blue Sky" laws of various states in connection with the issuance of the
   shares of FCB Common Stock pursuant to this Agreement and the Plan of
   Merger, and (e) the approval of this Agreement and the Plan of Merger by
   the requisite vote of the shareholders of OSB and FCB.

             3.5  Reports.  OSB and each of the OSB Subsidiaries have timely
   filed all reports, registrations and statements, together with any
   amendments required to be made with respect thereto, that they were
   required to file since July 1, 1992 with (i) the OTS, (ii) the Federal
   Deposit Insurance Corporation (the "FDIC"), (iii) any state regulatory
   authority (each a "State Regulator"), (iv) the SEC, and (v) any self-
   regulatory organization ("SRO") with jurisdiction over any of the
   activities of OSB or any of the OSB Subsidiaries (collectively "Regulatory
   Agencies"), and all other reports and statements required to be filed by
   them since July 1, 1992, including, without limitation, any report or
   statement required to be filed pursuant to the laws, rules or regulations
   of the United States, any state, or any Regulatory Agency, and have paid
   all fees and assessments due and payable in connection therewith, except
   where the failure to file such report, registration or statement or to pay
   such fees and assessments, either individually or in the aggregate, will
   not have a Material Adverse Effect on OSB.  Except for normal examinations
   conducted by a Regulatory Agency in the regular course of the business of
   OSB and the OSB Subsidiaries, no Regulatory Agency has initiated any
   proceeding or, to the best knowledge of OSB, investigation into the
   business or operations of OSB or any of the OSB Subsidiaries since July 1,
   1992.  There is no unresolved written violation, written criticism, or
   written exception by any Regulatory Agency with respect to any report or
   statement relating to any examinations of OSB or any of the OSB
   Subsidiaries, which is likely, either individually or in the aggregate, to
   have a Material Adverse Effect on OSB.

             3.6  Financial Statements.  OSB has previously made available to
   FCB copies of (a) the consolidated statements of financial condition of
   OSB and the OSB Subsidiaries as of December 31, 1994 and 1995, and the
   related consolidated statements of income, stockholders' equity and cash
   flows for the fiscal years ended December 31, 1993, 1994 and 1995,
   inclusive, as reported in OSB's Annual Report on Form 10-K for the fiscal
   year ended December 31, 1995 (the "OSB Form 10-K") filed with the SEC
   under the Securities Exchange Act of 1934, as amended (the "Exchange
   Act"), in each case accompanied by the audit report of Wipfli Ullrich
   Bertelson LLP, independent public accountants with respect to OSB, and (b)
   the unaudited consolidated statements of financial condition of OSB and
   the OSB Subsidiaries as of June 30, 1996, and the related unaudited
   consolidated statements of income, stockholders' equity and cash flows for
   the three- and six-month periods then ended as reported in OSB's Quarterly
   Report on Form 10-Q for the period ended June 30, 1996 filed with the SEC
   under the Exchange Act (the "OSB Second Quarter 10-Q").  The December 31,
   1995 consolidated statements of financial condition of OSB (including the
   related notes, where applicable) fairly present the consolidated financial
   position of OSB and the OSB Subsidiaries as of the dates thereof, and the
   other financial statements referred to in this Section 3.6 or included in
   the OSB Reports (including the related notes, where applicable) fairly
   present the results of the consolidated operations and stockholders'
   equity and consolidated financial position of OSB and the OSB Subsidiaries
   for the respective fiscal periods or as of the respective dates therein
   set forth, subject, in the case of the unaudited statements, to recurring
   audit adjustments normal in nature and amount; each of such statements
   (including the related notes, where applicable) comply in all material
   respects with applicable accounting requirements and with the published
   rules and regulations of the SEC with respect thereto; and each of such
   statements (including the related notes, where applicable) has been
   prepared in all material respects in accordance with generally accepted
   accounting principles ("GAAP") consistently applied during the periods
   involved, except, in each case, as indicated in such statements or in the
   notes thereto or, in the case of unaudited statements, as permitted by
   Form 10-Q.

             3.7  Broker's Fees.  Other than OSB's arrangement with Edelman &
   Co., Ltd. to serve as a financial advisor to OSB in connection with the
   Merger and related transactions contemplated by this Agreement and the
   Plan of Merger, neither OSB nor any OSB Subsidiary nor any of their
   respective officers or directors has employed any financial advisor,
   broker or finder or incurred any liability for any financial advisory
   fees,  broker's fees, commissions or finder's fees in connection with the
   Merger or related transactions contemplated by this Agreement and the Plan
   of Merger.

             3.8  Absence of Certain Changes or Events.

                  (a)  Except as publicly disclosed in the OSB Reports (as
        defined in Section 3.12) filed prior to the date hereof or as set

        OSB Subsidiaries taken as a whole have not incurred any material
        liability, except in the ordinary course of their respective
        businesses, and (ii) no event has occurred which has had,
        individually or in the aggregate, a Material Adverse Effect on OSB or
        will have a Material Adverse Effect on OSB.

                  (b)  Except as publicly disclosed in the OSB Reports filed
        prior to the date hereof, since December 31, 1995, OSB and the OSB
        Subsidiaries have conducted their respective businesses in all
        material respects in the ordinary and usual course.

             3.9  Legal Proceedings.

                  (a)  Except as set forth in Schedule 3.9, there are no
        pending or, to the best of OSB's knowledge, threatened, legal,
        administrative, arbitration or other proceedings, claims, actions or
        governmental or regulatory investigations of any nature against OSB
        or any of the OSB Subsidiaries or challenging the validity or
        propriety of the transactions contemplated by this Agreement, the
        Plan of Merger or the Option Agreements.

                  (b)  There is no injunction, order, judgment, decree, or
        regulatory restriction (other than regulatory restrictions that apply
        to similarly situated savings and loan holding companies or savings
        associations) imposed upon OSB, any of the OSB Subsidiaries or the
        assets of OSB or any of the OSB Subsidiaries. 

             3.10 Taxes and Tax Returns.

                  (a)  Each of OSB and the OSB Subsidiaries has duly filed
        all federal, state, county, foreign and, to the best of OSB's
        knowledge, local information returns and tax returns required to be
        filed by it (all such returns being accurate and complete in all
        material respects) and has duly paid or made provisions for the
        payment of all Taxes (as defined in Section 3.10(b)) and other
        governmental charges which have been incurred or are due or claimed
        to be due from it by federal, state, county, foreign or local taxing
        authorities on or prior to the date of this Agreement (including,
        without limitation, if and to the extent applicable, those due in
        respect of its properties, income, business, capital stock, deposits,
        franchises, licenses, sales and payrolls) other than Taxes or other
        charges which are not yet delinquent or are being contested in good
        faith and have not been finally determined.  The income tax returns
        of OSB and the OSB Subsidiaries remain open for the applicable
        statutory time periods and any deficiencies, penalties or assessments
        have been paid or provided for in OSB's consolidated financial
        statements.  There are no material disputes pending with respect to,
        or claims asserted for, Taxes or assessments upon OSB or any of the
        OSB Subsidiaries for which OSB does not have adequate reserves, nor
        has OSB or any of the OSB Subsidiaries given any currently effective
        waivers extending the statutory period of limitation applicable to
        any federal, state, county, foreign or local income tax return for
        any period.  In addition, (i) proper and accurate amounts have been
        withheld by OSB and each of the OSB Subsidiaries from their employees
        for all prior periods in compliance in all material respects with the
        tax withholding provisions of applicable federal, state, foreign and
        local laws, except where failure to do so would not have a Material
        Adverse Effect on OSB, (ii) federal, state, foreign, county and local
        returns which are accurate and complete in all material respects have
        been filed by OSB and each of the OSB Subsidiaries for all periods
        for which returns were due with respect to income tax withholding,
        Social Security and unemployment taxes, (iii) the amounts shown on
        such federal, state, foreign, local or county returns to be due and
        payable have been paid in full or adequate provision therefor has
        been included by OSB in its consolidated financial statements as of
        December 31, 1995, and (iv) there are no Tax liens upon any property
        or assets of OSB or any of the OSB Subsidiaries except liens for
        current taxes not yet due.  Except as set forth in Schedule 3.10(a),
        neither OSB nor any of the OSB Subsidiaries has been required to
        include in income any adjustment pursuant to Section 481 of the Code
        by reason of a voluntary change in accounting method initiated by OSB
        or any of the OSB Subsidiaries, and the Internal Revenue Service (the 
        "IRS") has not initiated or proposed any such adjustment or change in
        accounting method.  Except as set forth in the financial statements
        described in Section 3.6, neither OSB nor any of the OSB Subsidiaries
        has entered into a transaction which is being accounted for as an
        installment obligation under Section 453 of the Code.

                  (b)  As used in this Agreement, the term "Tax" or "Taxes"
        means all federal, state, county, local, and foreign income, excise,

             3.11 Employees.

                  (a)  Schedule 3.11(a) of the OSB Disclosure Schedules sets
        forth a true and complete list of each employee benefit plan,
        arrangement, commitment, agreement or understanding that is
        maintained as of the date of this Agreement (the "OSB Benefit Plans")

        "single employer" within the meaning of Section 4001 of the Employee
        Retirement Income Security Act of 1974, as amended ("ERISA").

                  (b)  OSB has heretofore delivered to FCB true and complete
        copies of each of the OSB Benefit Plans and certain related
        documents, including, but not limited to, (i) the Annual Report Form

        Section 401(a) of the Code is so qualified, (iii) no OSB Benefit Plan

        beyond their retirement or other termination of service, other than
        (A) coverage mandated by applicable law, (B) death benefits,

        OSB, the OSB Subsidiaries or the OSB ERISA Affiliates, or (D)

        employee (or his beneficiary), (iv) neither OSB, the OSB Subsidiaries
        nor any OSB ERISA Affiliate maintains or has ever maintained a plan

        nor any OSB ERISA Affiliate contributes to or has ever contributed to

        3(37) of ERISA, (vi) all contributions or other amounts payable by
        OSB or the OSB Subsidiaries as of the Effective Time with respect to

        Code, (vii) neither OSB, the OSB Subsidiaries nor any OSB ERISA
        Affiliate has engaged in a transaction in connection with which OSB,
        the OSB Subsidiaries or any OSB ERISA Affiliate reasonably could be
        subject to either a material civil penalty assessed pursuant to
        Section 409 or 502(i) of ERISA or a material tax imposed pursuant to
        Sections 4975 or 4976 of the Code, and (viii) to the best knowledge
        of OSB, there are no pending, threatened or anticipated claims (other
        than routine claims for benefits) by, on behalf of or against any of
        the OSB Benefit Plans or any trusts related thereto which are, in the
        reasonable judgment of OSB, likely, either individually or in the
        aggregate, to have a Material Adverse Effect on OSB.

             3.12 SEC Reports.  OSB and each of the OSB Subsidiaries has made
   available to FCB an accurate and complete copy of each (a) final
   registration statement, prospectus, report, schedule and definitive proxy
   statement filed since December 31, 1991 by OSB with the SEC pursuant to
   the Securities Act of 1933, as amended (the "Securities Act"), or the
   Exchange Act (collectively, "OSB Reports"), and (b) communication mailed
   by OSB to its shareholders since December 31, 1991.  None of the OSB
   Reports or such communications to shareholders, as of their respective
   dates, contained any untrue statement of a material fact or omitted to
   state any material fact required to be stated therein or necessary in
   order to make the statements therein, in light of the circumstances in
   which they were made, not misleading. Since December 31, 1991, OSB has
   timely filed all OSB Reports and other documents required to be filed by
   it under the Securities Act and the Exchange Act, and, as of their
   respective dates, all OSB Reports complied in all material respects with
   the published rules and regulations of the SEC with respect thereto.

             3.13 Compliance with Applicable Law.  OSB and each of the OSB
   Subsidiaries hold all licenses, franchises, permits and authorizations
   necessary for the lawful conduct of their respective businesses under and
   pursuant to all, and have complied with and are not in default under any,
   applicable laws, statutes, orders, rules, regulations, policies and/or
   guidelines of any Governmental Entity relating to OSB or any of the OSB
   Subsidiaries, except where the failure to hold such license, franchise,
   permit or authorization or such noncompliance or default would not,
   individually or in the aggregate, have a Material Adverse Effect on OSB.

             3.14 Certain Contracts.

                  (a)  Except as set forth in Schedule 3.14(a) of the OSB
        Disclosure Schedules, neither OSB nor any of the OSB Subsidiaries is
        a party to or bound by:

                       (i)  any contract, arrangement, commitment or
             understanding (whether written or oral) with respect to the
             employment or compensation of any directors, officers or
             employees;

                       (ii) any contract, arrangement, commitment or
             understanding (whether written or oral) which, upon the
             consummation of the transactions contemplated by this Agreement
             or the Plan of Merger will (either alone or upon the occurrence
             of any additional acts or events) result in any payment
             (including, without limitation, severance, unemployment
             compensation, golden parachute or otherwise) becoming due from
             OSB, FCB, the Surviving Corporation, or any of their respective
             Subsidiaries to any officer, director or employee thereof or to
             the trustee under any "rabbi trust" or similar arrangement;

                       (iii)     any contract, arrangement, commitment or
             understanding (whether written or oral) which materially
             restricts the conduct of any line of business by OSB; or

                       (iv) any contract, arrangement, commitment or
             understanding (whether written or oral), including any stock
             option plan, stock appreciation rights plan, restricted stock
             plan or stock purchase plan, any of the benefits of which will
             be increased or be required to be paid, or the vesting of the
             benefits of which will be accelerated, by the occurrence of any
             of the transactions contemplated by this Agreement or the Plan
             of Merger, or the value of any of the benefits of which will be
             calculated on the basis of any of the transactions contemplated
             by this Agreement or the Plan of Merger.

        OSB has previously made available to FCB true and correct copies of
        all employment and deferred compensation arrangements which are in
        writing and to which OSB or an OSB Subsidiary is a party.  Each
        contract, arrangement, commitment or understanding of the type
        described in this Section 3.14(a), is referred to herein as an "OSB
        Contract," and neither OSB nor any of the OSB Subsidiaries knows of,
        or has received notice of, any violation of any OSB Contract by any
        of the other parties thereto, which, individually or in the
        aggregate, would have a Material Adverse Effect on OSB.

                  (b)  (i) Each OSB Contract is valid and binding on OSB or
        the applicable OSB Subsidiary, as the case may be, and is in full
        force and effect, (ii) OSB and each of the OSB Subsidiaries has
        performed all obligations required to be performed by it to date
        under each OSB Contract to which it is a party, except where such
        noncompliance, individually or in the aggregate, would not have a
        Material Adverse Effect on OSB, and (iii) no event or condition
        exists which constitutes or, after notice or lapse of time or both,
        would constitute, a default on the part of OSB or any of the OSB
        Subsidiaries under any such OSB Contract, except where any such
        default, individually or in the aggregate, would not have a Material
        Adverse Effect on OSB.

             3.15 Agreements with Regulatory Agencies.  Neither OSB nor any
   of the OSB Subsidiaries is subject to any cease-and-desist or other order
   issued by, or is a party to any written agreement, consent agreement or
   memorandum of understanding with, or is a party to any commitment letter
   or similar undertaking to, or is subject to any order or directive by, or
   has been since December 31, 1991, a recipient of any supervisory letter
   from, or since December 31, 1991, has adopted any board resolutions at the
   request of any Regulatory Agency or other Governmental Entity that
   currently restricts the conduct of its business or that relates to its
   capital adequacy, compliance with laws, its credit policies, its
   management or its business (each, whether or not set forth in the OSB
   Disclosure Schedules, an "OSB Regulatory Agreement"), nor has OSB or any
   of the OSB Subsidiaries been advised since December 31, 1991 by any
   Regulatory Agency or other Governmental Entity that it is considering
   issuing or requesting any such OSB Regulatory Agreement.

             3.16 Other Activities of OSB and its OSB Subsidiaries.  Neither
   OSB nor any of the OSB Subsidiaries that is neither a savings association,
   a savings association operating subsidiary or a savings association
   service corporation directly or indirectly engages in any activity
   prohibited by the OTS.  Without limiting the generality of the foregoing,
   no equity investment of OSB or any OSB Subsidiary that is neither a
   savings association, a savings association operating subsidiary nor a
   savings association service corporation is prohibited by the OTS.

             3.17 Investment Securities.  Each of OSB and the OSB
   Subsidiaries has good and marketable title to all securities held by it
   (except securities sold under repurchase agreements or held in any
   fiduciary or agency capacity), free and clear of any Lien, except to the
   extent such securities are pledged in the ordinary course of business
   consistent with prudent banking practices to secure obligations of OSB or
   any of the OSB Subsidiaries.  Such securities are valued on the books of
   OSB and the OSB Subsidiaries in accordance with GAAP.

             3.18 Undisclosed Liabilities.  Except for those liabilities that
   are fully reflected or reserved against on the consolidated statement of
   financial condition of OSB included in the OSB Second Quarter 10-Q,
   liabilities disclosed in Schedule 3.18 of the OSB Disclosure Schedules,
   and liabilities incurred in the ordinary course of business consistent
   with past practice since June 30, 1996, neither OSB nor any of the OSB
   Subsidiaries has incurred any liability of any nature whatsoever (whether
   absolute, accrued, contingent or otherwise and whether due or to become
   due) that, either alone or when combined with all similar liabilities, has
   had, or could reasonably be expected to have, a Material Adverse Effect on
   OSB.

             3.19 Insurance.  Schedule 3.19 of the OSB Disclosure Schedules
   describes all policies of insurance in which OSB or any of the OSB
   Subsidiaries is named as an insured party or which otherwise relate to or
   cover any assets or properties of OSB or any of the OSB Subsidiaries. 
   Each of such policies is in full force and effect, and the coverage
   provided under such properties complies with the requirements of any
   contracts binding on OSB or any of the OSB Subsidiaries relating to such
   assets or properties.  Except as set forth in Schedule 3.19 of the OSB
   Disclosure Schedules, neither OSB nor any of the OSB Subsidiaries has
   received any notice of cancellation or termination with respect to any
   material insurance policy of OSB or any of the OSB Subsidiaries.

             3.20 Loan Loss Reserves.  The reserve for possible loan losses
   shown on the June 30, 1996 call report filed for OSB Bank is adequate in
   all material respects under the requirements of GAAP to provide for
   possible losses, net of recoveries relating to loans previously charged
   off, on loans outstanding (including accrued interest receivable) as of
   June 30, 1996.  The aggregate loan balances of OSB Bank at such date in
   excess of such reserves are, to the best knowledge and belief of OSB,
   collectible in accordance with their terms.

             3.21 Environmental Liability.  Except as set forth in Schedule
   3.21, there are no legal, administrative, arbitration or other
   proceedings, claims, actions, causes of action, private environmental
   investigations or remediation activities or governmental investigations of
   any nature pending or, to the best of OSB's knowledge, threatened against
   OSB seeking to impose, or that could reasonably result in the imposition,
   on OSB of any liability or obligation arising under common law or under
   any local, state, federal or foreign environmental statute, regulation or
   ordinance including, without limitation, the Comprehensive Environmental
   Response, Compensation and Liability Act of 1980, as amended ("CERCLA")
   which, insofar as reasonably can be foreseen, could have a Material
   Adverse Effect on OSB.

             Except as set forth in Schedule 3.21, to the best of OSB's
   knowledge, there is no reasonable basis for any proceeding, claim, action
   or governmental investigation that would impose any such liability or
   obligation which, insofar as reasonably can be foreseen, could have a
   Material Adverse Effect on OSB.  OSB is not subject to any agreement,
   order, judgment, decree, letter or memorandum by or with any court,
   governmental authority, regulatory agency or third party imposing any such
   liability or obligation which, insofar as reasonably can be foreseen,
   could have a Material Adverse Effect on OSB.

             3.22 Approval Delays. OSB knows of no reason why any of the
   Requisite Regulatory Approvals (as defined in Section 7.1(b)) should be
   denied or unduly delayed.

             3.23 Vote Required.  The approval by the holders of a majority
   of the votes entitled to be cast by all holders of OSB Common Stock to
   approve the Merger is the only vote of the holders of any class or series
   of the capital stock of OSB required for any of the transactions
   contemplated by this Agreement, the Plan of Merger and the Option
   Agreements; provided, however, that the approval of shareholders of OSB
   may be required for the repurchase of shares of OSB Common Stock pursuant
   to Section 8 of the OSB Stock Option Agreement under circumstances where
   Section 180.1134 of the WBCL would be applicable.

             3.24 Applicability of Certain Provisions of Wisconsin Law, Etc. 
   Assuming the representations and warranties of FCB made in Section 4.25
   are correct, none of the "control share voting" provisions of Section
   180.1150 of the WBCL, the "business combination" provisions of Sections
   180.1140 to 180.1144 of the WBCL, the "fair price" provisions of Section
   180.1130 to 180.1133 of the WBCL, or any other takeover related provisions
   of the WBCL (or, to the knowledge of OSB, any other similar state statute)
   or the Articles of Incorporation or By-Laws of OSB, are applicable to the
   transactions contemplated by this Agreement and the Plan of  Merger,
   including the granting or exercise of the OSB Stock Option Agreement,
   except for the limitations set forth in Article XIII(B) of the Articles of
   Incorporation of OSB.

             3.25 Ownership of FCB Common Stock.  Except as set forth in
   Schedule 3.25 of the OSB Disclosure Schedules and except pursuant to the
   terms of the FCB Stock Option Agreement, OSB does not "beneficially own"
   (as such term is defined for purposes of Section 13(d) of the Exchange
   Act) any shares of FCB Common Stock.
     
                                   ARTICLE IV
                      REPRESENTATIONS AND WARRANTIES OF FCB

             FCB hereby represents and warrants to OSB as follows:

             4.1  Corporate Organization.

                  (a)  FCB is a corporation duly organized and validly
        existing under the laws of the State of Wisconsin.  FCB has the
        corporate power and authority to own or lease all of its properties
        and assets and to carry on its business as it is now being conducted,
        and is duly licensed or qualified to do business in each jurisdiction
        in which the nature of the business conducted by it or the character
        or location of the properties and assets owned or leased by it makes
        such licensing or qualification necessary, except where the failure
        to be so licensed or qualified would not have a Material Adverse
        Effect on FCB. FCB is duly registered as a savings and loan holding
        company under HOLA.   True and complete copies of the Articles of
        Incorporation and By-Laws of FCB, as in effect as of the date of this
        Agreement, have previously been made available by FCB to OSB.

                  (b)  As of the date of this Agreement, FCB has, as its sole
        direct or indirect subsidiaries, FCB Bank, a federally-chartered
        savings association, Fox Cities Financial Services, Inc. and Fox
        Cities Investments, Inc. (the "FCB Subsidiaries").  Except as set
        forth on Schedule 4.1(b) of the disclosure schedules to this
        Agreement prepared and delivered by FCB (the "FCB Disclosure
        Schedules"), FCB does not own any voting stock or equity securities
        of any bank, corporation, partnership, limited liability company, or
        other organization, whether incorporated or unincorporated, other
        than the FCB Subsidiaries.

                  (c)  Each FCB Subsidiary (i) is duly organized and validly
        existing as a corporation under the laws of its jurisdiction of
        organization, (ii) is duly qualified to do business and in good
        standing in all jurisdictions (whether federal, state, local or
        foreign) where its ownership or leasing of property or the conduct of
        its business requires it to be so qualified and in which the failure
        to be so qualified would have a Material Adverse Effect on FCB, and
        (iii) has all requisite corporate power and authority to own or lease
        its properties and assets and to carry on its business as now
        conducted.  Except as set forth in Schedule 4.1(c) of the FCB
        Disclosure Schedules, none of the FCB Subsidiaries owns any voting
        stock or equity securities of any bank, corporation, partnership,
        limited liability company, or other organization, whether
        incorporated or unincorporated.

                  (d)  The minute books of FCB and of each of the FCB
        Subsidiaries have been made available to OSB and accurately reflect
        in all material respects all corporate meetings held or actions taken
        since January 1, 1992 by the shareholders and Boards of Directors of
        FCB and each FCB Subsidiary, respectively (including committees of
        the Boards of Directors of FCB and the FCB Subsidiaries).

             4.2  Capitalization.

                  (a)  The authorized capital stock of FCB consists of
        15,000,000 shares of common stock, $0.01 par value per share, of
        which, as of September 30, 1996, 2,459,614 shares were issued and
        outstanding and 5,000,000 shares of Preferred Stock, $0.01 par value
        per share, of which, as of September 30, 1996, none were issued and
        outstanding.  As of September 30, 1996, 449,886 shares of FCB Common
        Stock were held in treasury.  All of the issued and outstanding
        shares of FCB Common Stock have been duly authorized and validly
        issued and are fully paid, nonassessable (except as otherwise
        provided by Section 180.0622(2)(b) of the WBCL) and free of
        preemptive rights.  Except for the FCB Option Agreement and as set
        forth on Schedule 4.2(a) of the FCB Disclosure Schedules, FCB does
        not have and is not bound by any outstanding subscriptions, options,
        warrants, calls, commitments or agreements of any character calling
        for the purchase or issuance of any shares of FCB Common Stock or any
        other equity securities of FCB or any securities representing the
        right to purchase or otherwise receive any shares of the capital
        stock of FCB.  No shares of FCB Common Stock have been reserved for
        issuance, other than the shares of FCB Common Stock reserved for
        issuance under the FCB Option Agreement and the FCB Financial Corp.
        1993 Stock Option and Incentive Plan (the "FCB Option Plan").  Since
        September 30, 1996, FCB has not issued any shares of its capital
        stock or any securities convertible into or exercisable for any
        shares of its capital stock except upon exercise of stock options
        pursuant to the FCB Option Plan outstanding as of September 30, 1996
        and except with respect to the FCB Stock Option Agreement.

                  (b)  FCB owns, directly or indirectly, all of the issued
        and outstanding shares of capital stock of each of the FCB
        Subsidiaries, free and clear of any Liens.  All of the shares of
        capital stock of each FCB Subsidiary are duly authorized and validly
        issued and are fully paid, nonassessable (except as otherwise
        provided by Section 180.0622(2)(b) of the WBCL) and free of
        preemptive rights.  No FCB Subsidiary has or is bound by any
        outstanding subscriptions, options, warrants, calls, commitments or
        agreements of any character calling for the purchase or issuance of
        any shares of capital stock or any other equity security of such FCB
        Subsidiary or any securities representing the right to purchase or
        otherwise receive any shares of capital stock or any other equity
        security of such FCB Subsidiary.

             4.3  Authority; No Violation.  FCB has full corporate power and
   authority to execute and deliver each of this Agreement, the Plan of
   Merger and the Option Agreements, subject to shareholder and regulatory
   approvals, and to consummate the transactions contemplated hereby and
   thereby.  The execution and delivery of this Agreement, the Plan of Merger
   and the Option Agreements and the consummation of the transactions
   contemplated hereby and thereby have been duly and validly approved by the
   Board of Directors of FCB.  The Board of Directors of FCB has directed
   that this Agreement and the Plan of Merger and the transactions
   contemplated hereby and thereby be submitted to FCB's shareholders for
   approval at a meeting of such shareholders and, except for the adoption of
   this Agreement and the Plan of Merger and the transactions contemplated
   hereby and thereby by the affirmative vote of the holders of a majority of
   the outstanding shares of FCB Common Stock, no other corporate proceedings
   on the part of FCB are necessary to approve this Agreement, the Plan of
   Merger and the Option Agreements and to consummate the transactions
   contemplated hereby and thereby.  This Agreement and the Option Agreements
   have been duly and validly executed and delivered by FCB and (assuming due
   authorization, execution and delivery by OSB) constitute valid and binding
   obligations of FCB, enforceable against FCB in accordance with their
   respective terms.  Furthermore, the Plan of Merger, when executed and
   delivered by FCB and (assuming due authorization, execution and delivery
   by OSB), shall constitute a valid and binding obligation of FCB,
   enforceable against FCB in accordance with its terms.

             4.4  Consents and Approvals.  No consents or approvals of or
   filings or registrations with any  Governmental Entity or with any third
   party are necessary in connection with the execution and delivery by FCB
   of this Agreement, the Plan of Merger and the Option Agreements and the
   consummation by FCB of the Merger and the other transactions contemplated
   hereby and thereby except for (a) the filing by FCB and FCB Bank of an
   application with the OTS under HOLA and the approval of the OTS
   Application, (b) the filing with the SEC of the Joint Proxy Statement in
   definitive form relating to the meetings of OSB's and FCB's shareholders
   to be held in connection with this Agreement and the Plan of Merger and
   the transactions contemplated hereby and thereby in which such Joint Proxy
   Statement will be included as a prospectus, (c) the filing of Articles of
   Merger with the Wisconsin Department under the WBCL, (d) such filings and
   approvals as are required to be made or obtained under the securities or
   "Blue Sky" laws of various states in connection with the issuance of the
   shares of FCB Common Stock pursuant to this Agreement and the Plan of
   Merger, and (e) the approval of this Agreement and Plan of Merger by the
   requisite vote of the shareholders of FCB and OSB.

             4.5  Reports.  FCB and each of the FCB Subsidiaries have timely
   filed all reports, registrations and statements, together with any
   amendments required to be made with respect thereto, that they were
   required to file since October 1, 1993 with the Regulatory Agencies, and
   all other reports and statements required to be filed by them since
   October 1, 1993, including, without limitation, any report or statement
   required to be filed pursuant to the laws, rules or regulations of the
   United States, any state, or any Regulatory Agency, and have paid all fees
   and assessments due and payable in connection therewith, except where the
   failure to file such report, registration or statement or to pay such fees
   and assessments, either individually or in the aggregate, will not have a
   Material Adverse Effect on FCB.  Except for normal examinations conducted
   by a Regulatory Agency in the regular course of the business of FCB or the
   FCB Subsidiaries, no Regulatory Agency has initiated any proceeding or, to
   the best knowledge of FCB, investigation into the business or operations
   of FCB or any of the FCB Subsidiaries since October 1, 1993.  There is no
   unresolved written violation, written criticism, or written exception by
   any Regulatory Agency with respect to any report or statement relating to
   any examinations of FCB or any of the FCB Subsidiaries, which is likely,
   either individually or in the aggregate, to have a Material Adverse Effect
   on FCB.
    
             4.6  Financial Statements.  FCB has previously made available to
   OSB copies of (a) the consolidated statements of financial condition of
   FCB and the FCB Subsidiaries as of March 31, 1995 and 1996, and the
   related consolidated statements of income, shareholders' equity and cash
   flows for the fiscal years ended March 31, 1994, 1995 and 1996, inclusive,
   as reported in FCB's Annual Report on Form 10-K for the fiscal year ended
   March 31, 1996 (the "FCB Form 10-K") filed with the SEC under the Exchange
   Act, in each case accompanied by the audit report of Wipfli Ullrich
   Bertelson LLP, independent public accountants with respect to FCB, and (b)
   the unaudited consolidated statements of financial condition of FCB and
   the FCB Subsidiaries as of June 30, 1996, and the related unaudited
   consolidated statements of income, shareholders' equity and cash flows for
   the three-month period then ended as reported in FCB's Quarterly Report on
   Form 10-Q for the period ended June 30, 1996 filed with the SEC under the
   Exchange Act (the "FCB First Quarter 10-Q").  The March 31, 1996
   consolidated statements of financial condition of FCB (including the
   related notes, where applicable) fairly present the consolidated financial
   position of FCB and the FCB Subsidiaries as of the dates thereof, and the
   other financial statements referred to in this Section 4.6 or included in
   the FCB Reports (including the related notes, where applicable) fairly
   present the results of the consolidated operations and shareholders'
   equity and consolidated financial position of FCB and the FCB Subsidiaries
   for the respective fiscal periods or as of the respective dates therein
   set forth, subject, in the case of the unaudited statements, to recurring
   audit adjustments normal in nature and amount; each of such statements
   (including the related notes, where applicable) comply in all material
   respects with applicable accounting requirements and with the published
   rules and regulations of the SEC with respect thereto; and each of such
   statements (including the related notes, where applicable) has been
   prepared in all material respects in accordance with GAAP consistently
   applied during the periods involved, except, in each case, as indicated in
   such statements or in the notes thereto or, in the case of unaudited
   statements, as permitted by Form 10-Q.

             4.7  Broker's Fees.  Other than FCB's arrangement with RP
   Financial, LC. to serve as a financial advisor to FCB in connection with
   the Merger and related transactions contemplated by this Agreement and the
   Plan of Merger, neither FCB nor any FCB Subsidiary nor any of their
   respective officers or directors has employed any financial advisor,
   broker or finder or incurred any liability for any financial advisory
   fees,  broker's fees, commissions or finder's fees in connection with the
   Merger or related transactions contemplated by this Agreement and the Plan
   of Merger.

             4.8  Absence of Certain Changes or Events.

                  (a)  Except as publicly disclosed in the FCB Reports (as
        defined in Section 4.12) filed prior to the date hereof or as set
        forth in Schedule 4.8(a), since December 31, 1995, (i) FCB and the
        FCB Subsidiaries taken as a whole have not incurred any material
        liability, except in the ordinary course of their business, and (ii)
        no event has occurred which has had, individually or in the
        aggregate, a Material Adverse Effect on FCB or will have a Material
        Adverse Effect on FCB.

                  (b)  Except as publicly disclosed in the FCB Reports filed
        prior to the date hereof, since December 31, 1995, FCB and each FCB
        Subsidiary have carried on their respective businesses in all
        material respects in the ordinary and usual course.

             4.9  Legal Proceedings.

                  (a)  Except as set forth in Schedule 4.9, there are no
        pending or, to the best of FCB's knowledge, threatened, legal,
        administrative, arbitration or other proceedings, claims, actions or
        governmental or regulatory investigations of any nature against FCB
        or any of the FCB Subsidiaries or challenging the validity or
        propriety of the transactions contemplated by this Agreement, the
        Plan of Merger or the Option Agreements.

                  (b)  There is no injunction, order, judgment, decree, or
        regulatory restriction (other than regulatory restrictions that apply
        to similarly situated savings and loan holding companies or savings
        associations) imposed upon FCB, any of the FCB Subsidiaries or the
        assets of FCB or any of the FCB Subsidiaries. 

             4.10 Taxes and Tax Returns.  Each of FCB and the FCB
   Subsidiaries has duly filed all federal, state, county, foreign and, to
   the best of FCB's knowledge, local information returns and tax returns
   required to be filed by it on or prior to the date hereof (all such
   returns being accurate and complete in all material respects) and has duly
   paid or made provisions for the payment of all Taxes and other
   governmental charges which have been incurred or are due or claimed to be
   due from it by federal, state, county, foreign or local taxing authorities
   on or prior to the date of this Agreement (including, without limitation,
   if and to the extent applicable, those due in respect of its properties,
   income, business, capital stock, deposits, franchises, licenses, sales and
   payrolls) other than Taxes or other charges which are not yet delinquent
   or are being contested in good faith and have not been finally determined. 
   The income tax returns of FCB and the FCB Subsidiaries remain open for the
   applicable statutory time periods and any deficiencies, penalties or
   assessments have been paid or provided for in FCB's consolidated financial
   statements.  There are no material disputes pending with respect to, or
   claims asserted for, Taxes or assessments upon FCB or any of the FCB
   Subsidiaries for which FCB does not have adequate reserves, nor has FCB or
   any of the FCB Subsidiaries given any currently effective waivers
   extending the statutory period of limitation applicable to any federal,
   state, county, foreign or local income tax return for any period.  In
   addition, (i) proper and accurate amounts have been withheld by FCB and
   each of the FCB Subsidiaries from their employees for all prior periods in
   compliance in all material respects with the tax withholding provisions of
   applicable federal, state, foreign and local laws, except where failure to
   do so would not have a Material Adverse Effect on FCB, (ii) federal,
   state, foreign, county and local returns which are accurate and complete
   in all material respects have been filed by FCB and each of the FCB
   Subsidiaries for all periods for which returns were due with respect to
   income tax withholding, Social Security and unemployment taxes, (iii) the
   amounts shown on such federal, state, foreign, local or county returns to
   be due and payable have been paid in full or adequate provision therefor

   March 31, 1996, and (iv) there are no Tax liens upon any property or
   assets of FCB or any of the FCB Subsidiaries except liens for current
   taxes not yet due.  Except as set forth in Schedule 4.10(a), neither FCB
   nor any of the FCB Subsidiaries has been required to include in income any
   adjustment pursuant to Section 481 of the Code by reason of a voluntary
   change in accounting method initiated by FCB or any of the FCB
   Subsidiaries, and the IRS has not initiated or proposed any such
   adjustment or change in accounting method.  Except as set forth in the
   financial statements described in Section 4.6, neither FCB nor any of the
   FCB Subsidiaries has entered into a transaction which is being accounted
   for as an installment obligation under Section 453 of the Code.

                  (a)  Schedule 4.11 of the FCB Disclosure Schedules sets

        defined in Section 414(m) of the Code which includes FCB (an "FCB
        ERISA Affiliate"), all of which together with FCB would be deemed a
        "single employer" within the meaning of Section 4001 of ERISA.

                  (b)  FCB has heretofore delivered to OSB true and complete
        copies of the FCB Benefit Plans and certain related documents,
        including, but not limited to, (i) the  Annual Report Form 5500 for
        such FCB Benefit Plan (if applicable) for each of the last two years,
        and (ii) the most recent determination letter from the IRS (if
        applicable) for such FCB Benefit Plan.

                  (c)  (i) Each of the FCB Benefit Plans has been operated
        and administered in all material respects with applicable laws,
        including, but not limited to, ERISA and the Code, (ii) each of the
        FCB Benefit Plans intended to be "qualified" within the meaning of
        Section 401(a) of the Code is so qualified, (iii) no FCB Benefit Plan
        provides benefits, including, without limitation, death or medical
        benefits (whether or not insured), with respect to current or former
        employees of FCB, the FCB Subsidiaries or any FCB ERISA Affiliate
        beyond their retirement or other termination of service, other than
        (A) coverage mandated by applicable law, (B) death benefits,
        disability benefits or retirement benefits under any "employee
        pension plan" (as such term is defined in Section 3(2) of ERISA), (C)
        deferred compensation benefits accrued as liabilities on the books of
        FCB, the FCB Subsidiaries or the FCB ERISA Affiliates, or (D)
        benefits the full cost of which is borne by the current or former
        employee (or his beneficiary), (iv) neither FCB, the FCB Subsidiaries
        nor any FCB ERISA Affiliate maintains or has ever maintained a plan
        subject to Title IV of ERISA, (v) neither FCB, the FCB Subsidiaries
        nor any FCB ERISA Affiliate contributes to or has ever contributed to
        a "Multiemployer" pension plan (as such term is defined in Section
        3(37) of ERISA, (vi) all contributions or other amounts payable by
        FCB or the FCB Subsidiaries as of the Effective Time with respect to
        each FCB Benefit Plan in respect of current or prior plan years have
        been paid or accrued in accordance with GAAP and Section 412 of the
        Code, (vii) neither FCB, the FCB Subsidiaries nor any FCB ERISA
        Affiliate has engaged in a transaction in connection with which FCB,
        the FCB Subsidiaries or any ERISA Affiliate reasonably could be
        subject to either a material civil penalty assessed pursuant to
        Section 409 or 502(i) of ERISA or a material tax imposed pursuant to
        Sections 4975 or 4976 of the Code, and (viii) to the best knowledge
        of FCB, there are no pending, threatened or anticipated claims (other
        than routine claims for benefits) by, on behalf of or against any of
        the FCB Benefit Plans or any trusts related thereto which are, in the
        reasonable judgment of FCB, likely, either individually or in the
        aggregate, to have a Material Adverse Effect on FCB.

             4.12 SEC Reports.  FCB and each of the FCB Subsidiaries has made
   available to OSB an accurate and complete copy of each (a) final
   registration statement, prospectus, report, schedule and definitive proxy
   statement filed since March 31, 1993 by FCB with the SEC pursuant to the
   Securities Act or the Exchange Act (collectively, the "FCB Reports"), and
   (b) communication mailed by FCB to its shareholders since March 31, 1993. 
   None of the FCB Reports or such communications to shareholders, as of
   their respective dates, contained any untrue statement of a material fact
   or omitted to state any material fact required to be stated therein or
   necessary in order to make the statements therein, in light of the
   circumstances in which they were made, not misleading.  Since March 31,
   1993, FCB has timely filed all FCB Reports and other documents required to
   be filed by it under the Securities Act and the Exchange Act, and, as of
   their respective dates, all FCB Reports complied in all material respects
   with the published rules and regulations of the SEC with respect thereto.

             4.13 Compliance with Applicable Law.  FCB and each of the FCB
   Subsidiaries hold all licenses, franchises, permits and authorizations
   necessary for the lawful conduct of their respective businesses under and
   pursuant to all, and have complied with and are not in default under any,
   applicable laws, statutes, orders, rules, regulations, policies and/or
   guidelines of any Governmental Entity relating to FCB or any of the FCB
   Subsidiaries, except where the failure to hold such license, franchise,
   permit or authorization or such noncompliance or default would not,
   individually or in the aggregate, have a Material Adverse Effect on FCB.

             4.14 Certain Contracts.

                  (a)  Except as set forth in Schedule 4.14(a) of the FCB
        Disclosure Schedules, neither FCB nor any of the FCB Subsidiaries is
        a party to or bound by:  

                       (i)  any contract, arrangement, commitment or
             understanding (whether written or oral) with respect to the
             employment or compensation of any directors, officers or
             employees;

                       (ii) any contract, arrangement, commitment or
             understanding (whether written or oral) which, upon the
             consummation of the transactions contemplated by this Agreement
             or the Plan of Merger will (either alone or upon the occurrence
             of any additional acts or events) result in any payment
             (including, without limitation, severance, unemployment
             compensation, golden parachute or otherwise) becoming due from
             OSB, FCB, the Surviving Corporation, or any of their respective
             Subsidiaries to any officer, director or employee thereof or to
             the trustee under any "rabbi trust" or similar arrangement;

                       (iii)     any contract, arrangement, commitment or
             understanding (whether written or oral) which materially
             restricts the conduct of any line of business by FCB; or

                       (iv) any contract, arrangement, commitment or
             understanding (whether written or oral), including any stock
             option plan, stock appreciation rights plan, restricted stock
             plan or stock purchase plan, any of the benefits of which will
             be increased or be required to be paid, or the vesting of the
             benefits of which will be accelerated, by the occurrence of any
             of the transactions contemplated by this Agreement or the Plan
             of Merger, or the value of any of the benefits of which will be
             calculated on the basis of any of the transactions contemplated
             by this Agreement or the Plan of Merger.

        FCB has previously made available to OSB true and correct copies of
        all employment and deferred compensation arrangements which are in
        writing and to which FCB or an FCB Subsidiary is a party.  Each
        contract, arrangement, commitment or understanding of the type
        described in this Section 4.14(a), is referred to herein as an "FCB
        Contract," and neither FCB nor any of the FCB Subsidiaries knows of,
        or has received notice of, any violation of any FCB Contract by any
        of the other parties thereto, which, individually or in the
        aggregate, would have a Material Adverse Effect on FCB.

                  (b)  (i) each FCB Contract is valid and binding on FCB or
        the applicable FCB Subsidiary, as the case may be, and is in full
        force and effect, (ii) FCB and each of the FCB Subsidiaries has
        performed all obligations required to be performed by it to date
        under each FCB Contract to which it is a party, except where such
        noncompliance, individually or in the aggregate, would not have a
        Material Adverse Effect on FCB, and (iii) no event or condition
        exists which constitutes or, after notice or lapse of time or both,
        would constitute, a default on the part of FCB or any of the FCB
        Subsidiaries under any such FCB Contract, except where any such
        default, individually or in the aggregate, would not have a Material
        Adverse Effect on FCB.

             4.15 Agreements with Regulatory Agencies.  Neither FCB nor any
   of the FCB Subsidiaries is subject to any cease-and-desist or other order
   issued by, or is a party to any written agreement, consent agreement or
   memorandum of understanding with, or is a party to any commitment letter
   or similar undertaking to, or is subject to any order or directive by, or
   has been since March 31, 1993, a recipient of any supervisory letter from,
   or since March 31, 1993, has adopted any board resolutions at the request
   of any Regulatory Agency or other Governmental Entity that currently
   restricts the conduct of its business or that relates to its capital
   adequacy, compliance with laws, its credit policies, its management or its
   business (each, whether or not set forth in the FCB Disclosure Schedules,
   a "FCB Regulatory Agreement") nor has FCB or any of the FCB Subsidiaries
   been advised since March 31, 1993 by any Regulatory Agency or other
   Governmental Entity that it is considering issuing or requesting any such
   FCB Regulatory Agreement.

             4.16 Other Activities of FCB and its FCB Subsidiaries.  Neither
   FCB nor any of the FCB Subsidiaries that is neither a savings association,
   a savings association operating subsidiary or a savings association
   service corporation directly or indirectly engages in any activity
   prohibited by the OTS.  Without limiting the generality of the foregoing,
   no equity investment of FCB or any FCB Subsidiary that is neither a
   savings association, a savings association operating subsidiary nor a
   savings association service corporation is prohibited by the OTS.

             4.17 Investment Securities.  Each of FCB and the FCB
   Subsidiaries has good and marketable title to all securities held by it
   (except securities sold under repurchase agreements or held in any
   fiduciary or agency capacity), free and clear of any Lien, except to the
   extent such securities are pledged in the ordinary course of business
   consistent with prudent banking practices to secure obligations of FCB or
   any of the FCB Subsidiaries.  Such securities are valued on the books of
   FCB and the FCB Subsidiaries in accordance with GAAP.

             4.18 Undisclosed Liabilities.  Except for those liabilities that
   are fully reflected or reserved against on the consolidated statement of
   financial condition of FCB included in the  FCB First Quarter 10-Q,
   liabilities disclosed in Schedule 4.18 of the FCB Disclosure Schedules,
   and liabilities incurred in the ordinary course of business consistent
   with past practice since June 30, 1996, neither FCB nor any of the FCB
   Subsidiaries has incurred any liability of any nature whatsoever (whether
   absolute, accrued, contingent or otherwise and whether due or to become
   due) that, either alone or when combined with all similar liabilities, has
   had, or could reasonably be expected to have, a Material Adverse Effect on
   FCB.

             4.19 Insurance.  Schedule 4.19 of the FCB Disclosure Schedules
   describes all policies of insurance in which FCB or any of the FCB
   Subsidiaries is named as an insured party or which otherwise relate to or
   cover any assets or properties of FCB or any of the FCB Subsidiaries. 
   Each of such policies is in full force and effect, and the coverage
   provided under such properties complies with the requirements of any
   contracts binding on FCB or any of the FCB Subsidiaries relating to such
   assets or properties.  Except as set forth in Schedule 4.19 of the FCB
   Disclosure Schedules, neither FCB nor any of the FCB Subsidiaries has
   received any notice of cancellation or termination with respect to any
   material insurance policy of FCB or any of the FCB Subsidiaries.

             4.20 Loan Loss Reserves.  The reserve for possible loan losses
   shown on the June 30, 1996 call report filed for FCB Bank is adequate in
   all material respects under the requirements of GAAP to provide for
   possible losses, net of recoveries relating to loans previously charged
   off, on loans outstanding (including accrued interest receivable) as of
   June 30, 1996.  The aggregate loan balances of FCB Bank at such date in
   excess of such reserves of each of FCB Bank are, to the best knowledge and
   belief of FCB, collectible in accordance with their terms.

             4.21 Environmental Liability.  Except as set forth in Schedule
   4.21, there are no legal, administrative, arbitration or other
   proceedings, claims, actions, causes of action, private environmental
   investigations or remediation activities or governmental investigations of
   any nature pending or, to the best of FCB's knowledge, threatened against
   FCB seeking to impose, or that could reasonably result in the imposition,
   on FCB of any liability or obligation arising under common law or under
   any local, state, federal or foreign environmental statute, regulation or
   ordinance including, without limitation, CERCLA which, insofar as
   reasonably can be foreseen, could have a Material Adverse Effect on FCB. 
   Except as set forth in Schedule 4.21, to the best of FCB's knowledge,
   there is no reasonable basis for any such proceeding, claim, action or
   governmental investigation that would impose any such liability or
   obligation which, insofar as reasonably can be foreseen, could have a
   Material Adverse Effect on FCB.  FCB is not subject to any agreement,
   order, judgment, decree, letter or memorandum by or with any court,
   governmental authority, regulatory agency or third party imposing any such
   liability or obligation which, insofar as reasonably can be foreseen,
   could have a Material Adverse Effect on FCB.

             4.22 Approval Delays. FCB knows of no reason why any of the
   Requisite Regulatory Approvals (as defined in Section 7.1(b)) should be
   denied or unduly delayed.

             4.23 Vote Required.  The approval by the holders of a majority
   of the votes entitled to be cast by all holders of FCB Common Stock to
   approve the Merger (including the issuance of shares of FCB Common Stock
   in connection therewith) is the only vote of the holders of any class or
   series of the capital stock of FCB required for any of the transactions
   contemplated by this Agreement, the Plan of Merger and the Option
   Agreements; provided, however, that the approval of shareholders of FCB
   may be required for the repurchase of shares of FCB Common Stock pursuant
   to Section 8 of the FCB Stock Option Agreement under circumstances where
   Section 180.1134 of the WBCL would be applicable.

             4.24 Applicability of Certain Provisions of Wisconsin Law, Etc. 
   Assuming the representations and warranties of OSB made in Section 3.25
   are correct, none of the "control share voting" provisions of Section
   180.1150 of the WBCL, the "business combination" provisions of Sections
   180.1140 to 180.1144 of the WBCL, the "fair price" provisions of Section
   180.1130 to 180.1133 of the WBCL, or any other takeover related provisions
   of the WBCL (or, to the knowledge of FCB, any other similar state statute)
   or the Articles of Incorporation or By-Laws of FCB, are applicable to the
   transactions contemplated by this Agreement and the Plan of  Merger,
   including the granting or exercise of the FCB Stock Option Agreement,
   except for the limitations set forth in subparagraph B(4) of Article II of
   the Articles of Incorporation of FCB.

             4.25 Ownership of OSB Common Stock.  Except as set forth in
   Schedule 4.25 of the FCB Disclosure Schedules and except pursuant to the
   terms of the OSB Stock Option Agreement, FCB does not "beneficially own"
   (as such term is defined for purposes of Section 13(d) of the Exchange
   Act) any shares of OSB Common Stock.

                                    ARTICLE V
                    COVENANTS RELATING TO CONDUCT OF BUSINESS

             5.1  Conduct of Businesses Prior to the Effective Time.  During
   the period from the date of this Agreement to the Effective Time, except
   as expressly contemplated or permitted by this Agreement and the Plan of
   Merger (including the OSB Disclosure Schedules and the FCB Disclosure
   Schedules), each of FCB and OSB shall, and shall cause the FCB
   Subsidiaries and the OSB Subsidiaries, respectively, to (a) conduct its
   business in good faith  in the usual, regular and ordinary course
   consistent with past practice, (b) use reasonable efforts to maintain and
   preserve intact its business organization, employees and advantageous
   business relationships and retain the services of its key officers and key
   employees, and (c) take no action which would adversely affect or delay
   the ability of either FCB or OSB to obtain any necessary approvals of any
   Regulatory Agency or other governmental authority required for the
   transactions contemplated hereby or to perform its covenants and
   agreements under this Agreement, the Plan of Merger or the Option
   Agreements.

             5.2  Forbearances.  During the period from the date of this
   Agreement to the Effective Time, except as set forth in the OSB Disclosure
   Schedules or the FCB Disclosure Schedules, as the case may be, and, except
   as expressly contemplated or permitted by this Agreement, the Plan of
   Merger or the Option Agreements, neither FCB nor OSB shall, nor shall FCB
   or OSB permit the FCB Subsidiaries or OSB Subsidiaries, respectively to,
   without the prior written consent of the other:

                  (a)  other than in the ordinary course of business

        Subsidiaries or of any of the OSB Subsidiaries to OSB, or
        indebtedness of FCB to any of the FCB Subsidiaries or of any of the
        FCB Subsidiaries to FCB, it being understood and agreed that

        include, without limitation, the creation of deposit liabilities,
        purchases of Federal funds, sales of certificates of deposit and
        entering into repurchase agreements), (ii) assume, guarantee, endorse

                  (b)  (i) adjust, split, combine or reclassify any capital
        stock, (ii) make, declare or pay any dividend or make any other
        distribution on, any shares of its capital stock or any securities or

        cash dividends at a rate not in excess of $0.18 per share of FCB
        Common Stock, and (B) in the case of OSB, for regular quarterly cash

        given to FCB as soon as practicable thereafter); (iv) grant any stock
        appreciation rights or grant any individual, corporation or other
        entity any right to acquire any shares of its capital stock, or (iv)

        the exercise of stock options outstanding as of the date of this
        Agreement, or (B) the Option Agreements);

                  (c)  sell, transfer, mortgage, encumber or otherwise
        dispose of any of its properties or assets to any individual,
        corporation or other entity other than a Subsidiary, or cancel,
        release or assign any indebtedness to any such person or any claims
        held by any such person, except in the ordinary course of business
        consistent with past practice or pursuant to contracts or agreements
        in force at the date of this Agreement;

                  (d)  except for transactions in the ordinary course of

                  (f)  other than in the ordinary course of business
        consistent with past practice, increase in any manner the
        compensation or fringe benefits of any of its employees (it being
        understood and agreed that an increase in any manner the compensation
        of any employee in the ordinary course of business consistent with
        past practice shall include, without limitation, an increase in Mr.
        Rothenbach's base salary to an amount not to exceed $125,000
        annually), or pay any pension or retirement allowance not required by
        any existing plan or agreement to any such employees or become a
        party to, amend or commit itself to any pension, retirement, profit-
        sharing or welfare benefit plan or agreement or employment agreement

        preceding fiscal year and (ii) any bonus paid by OSB or the OSB

                  (g)  grant, amend or modify in any material respect any

        are outstanding as of the date of this Agreement in each case solely
        to provide full vesting conditioned upon and effective as of the

        liabilities or obligations (whether absolute, accrued, asserted or
        unasserted, contingent or otherwise), other than the payment,
        discharge or satisfaction, in the ordinary course of business
        consistent with past practice (which includes the payment of final
        and unappealable judgments) or in accordance with their terms, of
        liabilities reflected or reserved against in, or contemplated by, the
        most recent consolidated financial statements (or the notes thereto)
        of such party included in such party's reports filed with the SEC, or
        incurred in the ordinary course of business consistent with past
        practice;

                  (i)  take any action that would prevent or impede the
        Merger from qualifying as a reorganization within the meaning of
        Section 368 of the Code; provided, however, that nothing contained
        herein shall limit the ability of OSB or FCB to exercise its rights
        under the OSB Option Agreement or the FCB Option Agreement, as the
        case may be;

                  (j)  amend its articles of incorporation or its bylaws;

                  (k)  other than in prior consultation with the other party
        to this Agreement, restructure or materially change its investment

        or otherwise, or the manner in which the portfolio is classified or
        reported;

                  (l)  take any action that is intended or may reasonably be
        expected to result in any of its representations and warranties set
        forth in this Agreement being or becoming untrue in any material
        respect at any time prior to the Effective Time, or in any of the
        conditions to the Merger set forth in Article VII not being satisfied
        or in a violation of any provision of this Agreement, the Plan of
        Merger or the Option Agreements, except, in every case, as may be
        required by applicable law; or

                  (m)  agree to, or make any commitment to, take any of the
        actions prohibited by this Section 5.2.

                                   ARTICLE VI
                              ADDITIONAL AGREEMENTS

             6.1  Regulatory Matters; Cooperation with Respect to Filing.

                  (a)  (i) FCB shall promptly prepare and file with the SEC
        the Joint Proxy Statement in preliminary form; (ii) FCB shall
        promptly prepare and file an application with the OTS, for approval
        to consummate the transactions contemplated by this Agreement, the
        Plan of Merger and, to the extent required, the Option Agreements. 
        Each of FCB and OSB shall use all reasonable efforts to have the S-4,
        in which the Joint Proxy Statement will be included as a prospectus,
        declared effective under the Securities Act  as promptly as
        practicable after such filing and to mail or deliver the Joint Proxy
        Statement to their respective shareholders.  FCB shall also 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 and the Plan of Merger,
        and OSB shall furnish all information concerning OSB and the holders
        of the OSB Common Stock as may be reasonably requested by FCB in
        connection with any such action.

                  (b)  The parties hereto shall cooperate with each other and
        shall each use reasonable efforts to promptly prepare and file all
        necessary documentation, to effect all applications, notices,
        petitions and filings, to obtain as promptly as practicable all
        permits, consents, approvals and authorizations of all third parties
        and Governmental Entities which are necessary or advisable to
        consummate the transactions contemplated by this Agreement and the
        Plan of Merger (including, without limitation, the Merger), and to
        comply with the terms and conditions of all such permits, consents,
        approvals and authorizations of all such Governmental Entities.  FCB
        and OSB shall have the right to review in advance, and, to the extent
        practicable, each will consult the other on, in each case subject to
        applicable laws relating to the exchange of information, all the
        information relating to FCB or OSB, as the case may be, and the FCB
        Subsidiaries and OSB Subsidiaries, respectively, which appears in any
        filing made with, or written materials submitted to, any third party
        or any Governmental Entity in connection with the transactions
        contemplated by this Agreement and the Plan of Merger.  In exercising
        the foregoing right, each of the parties hereto shall act reasonably
        and as promptly as practicable.  The parties hereto agree that they
        will consult with each other with respect to the obtaining of all
        permits, consents, approvals and authorizations of all third parties
        and Governmental Entities necessary or advisable to consummate the
        transactions contemplated by this Agreement and the Plan of Merger,
        and each party will keep the other apprised of the status of matters
        relating to completion of the transactions contemplated herein.

                  (c)  FCB and OSB shall, upon request, furnish each other
        with all information concerning themselves, and the FCB Subsidiaries
        and the OSB Subsidiaries, respectively, directors, officers and
        shareholders and such other matters as may be reasonably necessary or
        advisable in connection with the Joint Proxy Statement, the S-4 or
        any other statement, filing, notice or application made by or on
        behalf of FCB or OSB or the FCB Subsidiaries and OSB Subsidiaries, as
        the case may be, to any Governmental Entity in connection with the
        Merger and the other transactions contemplated by this Agreement and
        the Plan of Merger.  FCB covenants and agrees that none of the
        information which  is furnished by FCB for inclusion, or which is
        included, in the S-4, the Joint Proxy Statement or any other
        statement, filing, notice or application made by or on behalf of FCB
        or OSB or the FCB Subsidiaries or the OSB Subsidiaries, as the case
        may be, to any Governmental Entity in connection with the Merger and
        the other transactions contemplated by this Agreement and the Plan of
        Merger will, at the respective times such documents are filed and, in
        the case of the S-4, when it becomes effective and, with respect to
        the Joint Proxy Statement, when mailed or at the time of the meetings
        of the shareholders of FCB and OSB, be false or misleading with
        respect to any material fact or shall omit to state any material fact
        necessary in order to make the statements therein, in light of the
        circumstances in which they were made, not misleading.  OSB covenants
        and agrees that none of the information which is furnished by OSB for
        inclusion, or which is included, in the S-4, the Joint Proxy
        Statement or any other statement, filing, notice or application made
        by or on behalf of FCB or OSB or the FCB Subsidiaries or the OSB
        Subsidiaries, as the case may be, to any Governmental Entity in
        connection with the Merger and the other transactions contemplated by
        this Agreement and the Plan of Merger will, at the respective times
        such documents are filed and, in the case of the S-4, when it becomes
        effective and, with respective to the Joint Proxy Statement, when
        mailed or at the time of the meetings of the shareholders of FCB and
        OSB, be false or misleading with respect to any material fact or
        shall omit to state any material fact necessary in order to make the
        statements therein, in light of the circumstances in which they were
        made, not misleading.  Notwithstanding the foregoing, FCB shall have
        no responsibility for the truth or accuracy of any information with
        respect to OSB or the OSB Subsidiaries included in the S-4, the Joint
        Proxy Statement, or any other statement, filing, notice or
        application filed with any Governmental Entity in connection with the
        Merger and the other transactions contemplated by this Agreement and
        the Plan of Merger, and OSB shall have no responsibility for the
        truth or accuracy of any information with respect to FCB or the FCB
        Subsidiaries included in the S-4, the Joint Proxy Statement, or any
        other statement, filing, notice or application filed with any
        Governmental Entity in connection with the Merger and the other
        transactions contemplated by this Agreement and the Plan of Merger.

                  (d)  FCB and OSB shall promptly advise one another upon
        receiving any communication from any Governmental Entity whose
        consent or approval is required for consummation of the transactions
        contemplated by this Agreement and the Plan of Merger which causes
        such party to believe that there is a reasonable likelihood that any
        Requisite Regulatory Approval will not be obtained or that the
        receipt of any such approval will be materially delayed.

             6.2  Access to Information; Due Diligence.

                  (a)  Upon reasonable notice and subject to applicable laws
        relating to the exchange of information, each of FCB and OSB shall,
        and shall cause the FCB Subsidiaries and the OSB Subsidiaries,
        respectively, to, afford to the officers, employees, accountants,
        counsel and other representatives of the other party, access, during
        normal business hours during the period prior to the Effective Time,
        to all its properties, books, contracts, commitments and records and,
        during such period, each of FCB and OSB shall, and shall cause the
        FCB Subsidiaries and the OSB Subsidiaries, respectively, to, make
        available to the other party (i) a copy of each report, schedule,
        registration statement and other document filed or received by it
        during such period pursuant to the requirements of federal securities
        laws or federal or state banking laws, and (ii) all other information
        concerning its business, properties and personnel as such party may
        reasonably request.  Neither FCB, OSB, the FCB Subsidiaries nor the
        OSB Subsidiaries shall be required to provide access to or to
        disclose information where such access or disclosure would (A)
        violate or prejudice the rights of FCB's or OSB's, as the case may
        be, customers or contravene any law, rule, regulation, order,
        judgment, decree, fiduciary duty or binding agreement entered into
        prior to the date of this Agreement, or (B) impair any attorney-
        client privilege of the disclosing party.  The parties hereto will
        make appropriate substitute disclosure arrangements under
        circumstances in which the restrictions of the preceding sentence
        apply.

                  (b)  Each of FCB and OSB shall hold all information
        furnished by or on behalf of the other party or the FCB Subsidiaries
        or the OSB Subsidiaries, as the case may be, or their representatives
        pursuant to Section 6.2(a) in confidence and shall return all
        documents containing any information concerning the properties,
        business and assets of each other party that may have been obtained
        in the course of negotiations or examination of the affairs of each
        other party either prior or subsequent to the execution of this
        Agreement (other than such information as shall be in the public
        domain or otherwise ascertainable from public or outside sources) and
        shall destroy any information, analyses or the like derived from such
        confidential information.  Each of FCB and OSB shall use such
        information solely for the purpose of conducting business, legal and
        financial reviews of the other party and for such other purposes as
        may be related to this Agreement and the Plan of Merger.

                  (c)  No investigation by either of the parties or their
        respective representatives shall affect the representations and
        warranties of the other set forth herein.  Without limitation of the
        foregoing, each party shall promptly notify the other party of any
        information obtained by such party during the course of any due
        diligence conducted by such party or its representatives in
        accordance with this Section 6.2 which is materially inconsistent
        with any representation or warranty made by the other party under
        this Agreement; provided, however, that either party's failure to
        provide such notice to the other party shall not, in turn, be deemed
        to constitute a material breach of such party's obligations under
        this Agreement and the Plan of Merger.

             6.3  Shareholders' Approvals.  Each of FCB and OSB shall call a
   meeting of its shareholders to be held as soon as reasonably practicable
   for the purpose of voting upon this Agreement and the Plan of Merger (and,
   in the case of FCB, the issuance of shares of FCB Common Stock in the
   Merger), and, subject to the terms and conditions of this Agreement and
   the Plan of Merger, each of FCB and OSB shall use reasonable efforts to
   cause such meetings to occur on the same date and each shall use all
   reasonable efforts to obtain shareholder approval of this Agreement, the
   Plan of Merger and the Merger.

             6.4  Legal Conditions to Merger.  Each of FCB and OSB shall, and
   shall cause the FCB Subsidiaries and the OSB Subsidiaries, respectively,
   to use reasonable efforts (a) to take, or cause to be taken, all actions
   necessary, proper or advisable to comply promptly with all legal
   requirements which may be imposed on such party with respect to the Merger
   and, subject to the conditions set forth in Article VII hereof, to
   consummate the transactions contemplated by this  Agreement and the Plan
   of Merger and (b) to obtain (and to cooperate with the other party to
   obtain) any consent, authorization, order or approval of, or any exemption
   by, any Governmental Entity and any other third party which is required to
   be obtained by FCB, the FCB Subsidiaries, OSB or the OSB Subsidiaries in
   connection with the Merger and the other transactions contemplated by this
   Agreement, the Plan of Merger and the Option Agreements.

             6.5  Listing of Shares.  FCB shall use all reasonable efforts to
   cause the shares of FCB Common Stock issuable in the Merger to be approved
   for listing on The Nasdaq Stock Market.

             6.6  Indemnification; Directors' and Officers' Insurance.

                  (a)  In the event of any threatened or actual claim,
        action, suit, proceeding or investigation, whether civil, criminal or
        administrative, including, without limitation, any such claim,
        action, suit, proceeding or investigation in which any individual who
        is now, or has been at any time prior to the date of this Agreement,
        or who becomes prior to the Effective Time, a director or officer or
        employee of FCB, the FCB Subsidiaries, OSB or the OSB Subsidiaries
        (the "Indemnified Parties"), is, or is threatened to be, made a party
        based in whole or in part on, or arising in whole or in part out of,
        or pertaining to (i) the fact that he or she is or was a director,
        officer or employee of FCB, the FCB Subsidiaries, OSB or the OSB
        Subsidiaries or any of their respective predecessors, or (ii) this
        Agreement, the Plan of Merger or the Option Agreements or any of the
        transactions contemplated hereby or thereby, whether in any case
        asserted or arising before or after the Effective Time, the parties
        hereto agree to cooperate and use reasonable efforts to defend
        against and respond thereto.  It is understood and agreed that after
        the Effective Time, the Surviving Corporation shall indemnify and
        hold harmless, as and to the fullest extent permitted by law, each
        such Indemnified Party against any losses, claims, damages,
        liabilities, costs, expenses (including reasonable attorney's fees
        and expenses in advance of the final disposition of any claim, suit,
        proceeding or investigation incurred by each Indemnified Party to the
        fullest extent permitted by law upon receipt of any undertaking
        required by applicable law), judgments, fines and amounts paid in
        settlement in connection with any such threatened or actual claim,
        action, suit, proceeding or investigation, and in the event of any
        such threatened or actual claim, action, suit, proceeding or
        investigation (whether asserted or arising before or after the
        Effective Time), the Indemnified Parties may retain counsel
        reasonably satisfactory to them after consultation with the Surviving
        Corporation; provided, however, that (A) the Surviving Corporation
        shall have the right to assume the defense thereof and upon such
        assumption the Surviving Corporation shall not be liable to any
        Indemnified Party for any legal expenses of other counsel or any
        other expenses subsequently incurred by any Indemnified Party in
        connection with the defense thereof, except that if the Surviving
        Corporation elects not to assume such defense or counsel for the
        Indemnified Parties reasonably advises the Indemnified Parties that
        there are issues which raise conflicts of interest between the
        Surviving Corporation and the Indemnified Parties, the Indemnified
        Parties may retain counsel reasonably satisfactory to them after
        consultation with the Surviving Corporation, and the Surviving
        Corporation shall pay the reasonable fees and expenses of such
        counsel for the Indemnified Parties, (B) the Surviving Corporation
        shall be obligated pursuant to this paragraph to pay for only one
        firm of counsel for all Indemnified Parties, unless an Indemnified
        Party shall have reasonably concluded, based on the advice of
        counsel, that there is a material conflict of interest between the
        interests of such Indemnified Party and the interests of one or more
        other Indemnified Parties and that the interests of such Indemnified
        Party will not be adequately represented unless separate counsel is
        retained, in which case, the Surviving Corporation shall be obligated
        to pay such separate counsel, (C) the Surviving Corporation shall not
        be liable for any settlement effected without its prior written
        consent (which consent shall not be unreasonably withheld) and (D)
        the Surviving Corporation shall have no obligation hereunder to any
        Indemnified Party when and if a court of competent jurisdiction shall
        ultimately determine, and such determination shall have become final
        and nonappealable, that indemnification of such Indemnified Party in
        the manner contemplated hereby is prohibited by applicable law.  Any
        Indemnified Party wishing to claim Indemnification under this Section
        6.6, upon learning of any such claim, action, suit, proceeding or
        investigation, shall notify the Surviving Corporation thereof,
        provided that the failure to so notify shall not affect the
        obligations of the Surviving Corporation under this Section 6.6
        except to the extent such failure to notify materially prejudices the
        Surviving Corporation.  The Surviving Corporation's obligations under
        this Section 6.6 shall continue in full force and effect for a period
        of five years from the Effective Time (or the period of the
        applicable statute of limitations, if longer); provided, however,
        that all rights to indemnification in respect of any claim (a
        "Claim") asserted or made within such period shall continue until the
        final disposition of such Claim.

                  (b)  The Surviving Corporation shall use reasonable efforts
        (i) to obtain, after the Effective Time, directors' and officers'
        liability insurance coverage for the officers and directors of the
        Surviving Corporation, to the extent that the same is economically
        practicable, and (ii) either (A) to cause the individuals serving as
        officers and directors of FCB, the FCB Subsidiaries, OSB or the OSB
        Subsidiaries immediately prior to the Effective Time to be covered
        for a period of three years from the Effective Time by the directors'
        and officers' liability insurance policies maintained by the
        Surviving Corporation, or to (B) substitute therefor policies of at
        least the same coverage and amounts containing terms and conditions
        which are not less advantageous than the policies previously
        maintained by FCB and OSB, respectively, with respect to acts or
        omissions occurring prior to the Effective Time which were committed
        by such officers and directors in their capacity as such; provided,
        however, that in no event shall the Surviving Corporation be required
        to expend per year an amount in excess of 120% of the premium for
        such insurance paid by FCB during its 1997 fiscal year (the
        "Insurance Amount") to maintain or procure insurance coverage
        pursuant to clause (ii) of this sentence, and provided further that
        if the Surviving Corporation is unable to maintain or obtain the
        insurance called for by clause (ii) of this sentence, the Surviving
        Corporation shall use reasonable efforts to obtain as much comparable
        insurance as available for the Insurance Amount.

                  (c)  In the event the Surviving Corporation or any of its
        successors or assigns (i) consolidates with or merges into any other
        person and shall not be the continuing or surviving corporation or
        entity of such consolidation or merger, or (ii) transfers or conveys
        all or substantially all of its properties and assets to any person,
        then, and in each such case, to the extent necessary, proper
        provision shall be made so that the successors and assigns of the
        Surviving Corporation assume the obligations set forth in this
        Section 6.6.

                  (d)  The provisions of this Section 6.6 are intended to be
        for the benefit of, and shall be enforceable by, each Indemnified
        Party and his or her heirs and representatives.

             6.7  Additional Agreements.  In case at any time after the
   Effective Time any further action is necessary or desirable to carry out
   the purposes of this Agreement, the Plan of Merger or the Option
   Agreements or to vest FCB with full title to all properties, assets,
   rights, approvals, immunities and franchises of any of the parties to the
   Merger, the proper officers and directors of each party to this Agreement
   shall take, or cause the proper officers and directors of the FCB
   Subsidiaries or OSB Subsidiaries to take, as the case may be, all such
   necessary action as may be reasonably requested by FCB.

             6.8  Advice of Changes.  Between the date hereof and the
   Effective Time, FCB and OSB shall promptly provide notice to the other
   party of any change or event having a Material Adverse Effect on it or
   which it believes would or would be reasonably likely to cause or
   constitute a material breach of any of its representations, warranties or
   covenants contained herein.

             6.9  No Conduct Inconsistent with this Agreement.
    
                  (a)  Neither FCB nor OSB shall:

                       (i)  solicit, encourage or authorize any individual,
             corporation or other entity to solicit from any third party any
             inquires or proposals relating to the disposition of its
             business or assets, or the acquisition of its capital stock, or
             the merger of it or any of the FCB Subsidiaries or the OSB
             Subsidiaries, respectively, with any corporation or other entity
             other than as provided by this Agreement except pursuant to a
             written direction from a regulatory authority; or 

                       (ii) negotiate with or entertain any proposals from
             any other person for any such transaction wherein the business,
             assets or capital stock of it or the FCB Subsidiaries or the OSB
             Subsidiaries, respectively, would be acquired, directly or
             indirectly, by any party other than as provided by this
             Agreement, except pursuant to a written direction from any
             regulatory authority or upon the receipt of an unsolicited offer
             from a third party where the Board of Directors of the party
             receiving such offer reasonably believes, upon the written
             opinion of counsel, that its fiduciary duties require it to
             enter into discussions with such party.  Each party shall
             promptly notify the other of all of the relevant details
             relating to all inquiries and proposals which it may receive
             relating to any proposed disposition of its business or assets,
             or the acquisition of its capital stock, or the merger of it or
             the FCB Subsidiaries or the OSB Subsidiaries, respectively, with
             any corporation or other entity other than as provided by this
             Agreement and shall keep the other party informed of the status
             and details of any such inquiry or proposal, and shall give the
             other party five days' advance notice of any agreement to be
             entered into with, or any information to be supplied to, any
             person making such inquiry or proposal; or

                  (b)  Nothing contained herein shall prohibit a party from
        disclosing to its shareholders a position contemplated by Rule 14e-
        2(a) under the Exchange Act with respect to a tender offer for that
        party's common stock.

             6.10 Employee Benefit Plans.  

                  (a)  At the Effective Time, the Oshkosh Savings Bank, FSB
        Employee Stock Ownership Plan (the "OSB ESOP") shall be merged with
        and into the FCB Financial Corp. Employee Stock Ownership Plan (the
        "FCB ESOP"), with all participants in the OSB ESOP at the time of
        such merger of the OSB ESOP and the FCB ESOP to become participants
        in the FCB ESOP.  The shares of OSB Common Stock currently held by
        the OSB ESOP which are allocated to the accounts of such participants
        shall be converted into shares of FCB Common Stock in accordance with
        Section 1.4 hereof.  The unallocated shares of OSB Common Stock
        currently held by the OSB ESOP shall be converted into shares of FCB
        Common Stock in accordance with Section 1.4 hereof, and thereafter
        shall be held in the Suspense Account under the FCB ESOP and
        allocated to the participants in the FCB ESOP (including, without
        limitation, such employees of OSB Bank who become employees of FCB
        Bank following the Effective Date) according to the terms and
        provisions of the FCB ESOP.  FCB shall assume the loan between OSB
        and the OSB ESOP.  Each OSB Bank employee's period of employment with
        OSB Bank shall be counted for all purposes under the FCB ESOP,
        including, without limitation, for purposes of service credit,
        eligibility and vesting.  Each OSB Bank employee's compensation
        attributable to employment with OSB Bank shall be counted for all
        purposes under the FCB ESOP, including, without limitation, for
        purposes of contribution allocations.  Each active participant in the
        OSB ESOP or the FCB ESOP as of the day immediately prior to the
        Closing Date who is not employed by FCB Bank as of the Closing Date
        or who is terminated by FCB Bank (other than for cause) within one
        year after the Closing Date shall be fully vested in their account
        balance under the OSB ESOP or the FCB ESOP, as the case may be, as of
        the Closing Date or the date of termination of employment,
        respectively.

                  (b)  Effective as of the Effective Time, the Oshkosh
        Savings Bank, FSB 401(k) Profit Sharing Plan (the "OSB PSP") shall be
        merged with and into the Fox Cities Bank, FSB Employees Savings and
        Investment (the "FCB PSP"), with all participants in the OSB PSP at
        the time of such merger of the OSB PSP and the FCB PSP to become
        participants in the FCB PSP.  Benefits under the FCB PSP shall
        thereafter be available to participants in the FCB PSP (including,
        without limitation, such employees of OSB Bank who become employees
        of FCB Bank after the Effective Time and are eligible to participate
        in the FCB PSP) according to the terms and provisions of the FCB PSP. 
        Each OSB Bank employee's period of employment with OSB Bank shall be
        counted for all purposes under the FCB PSP, including, without
        limitation, for purposes of service credit, eligibility and vesting. 
        Each OSB Bank employee's compensation attributable to employment with
        OSB Bank shall be counted for all purposes under the FCB PSP,
        including, without limitation, for purposes of contribution
        allocations.  Each active participant in the OSB PSP or the FCB PSP
        as of the day immediately prior to the Closing Date who is not
        employed by FCB Bank as of the Closing Date or who is terminated by
        FCB Bank (other than for cause) within one year after the Closing
        Date shall be fully vested in their account balance under the FCB PSP
        or the OSB PSP, as the case may be, as of the Closing Date or the
        date of termination of employment, respectively.

                  (c)  At the Effective Time, each OSB Bank employee shall
        immediately become eligible to participate in all employee welfare
        benefit plans and other fringe benefits programs offered or
        maintained by the Surviving Corporation and the Surviving Bank on the
        same terms and conditions that the Surviving Corporation and the
        Surviving Bank may make available to their officers and employees,
        including, without limitation, any health, life, long-term
        disability, short-term disability, severance, vacation or paid time
        off programs (the "FCB Welfare Plans").  Each OSB Bank employee's
        period of employment and compensation with OSB Bank shall be counted
        for all purposes under the FCB Welfare Plans, including, without
        limitation, for purposes of service credit, eligibility and benefit
        accrual.  Any expenses incurred by an OSB Bank employee under the OSB
        Bank's employee welfare benefit plans (such as deductibles or co-
        payments), shall be counted for all purposes under the FCB Welfare 
        Plans.  FCB Bank shall provide insurance coverage (for which FCB or
        FCB Bank may act as the self-insurer) for pre-existing medical
        conditions (to the extent such condition is currently covered under
        the OSB Bank plan, and such condition would be covered under FCB
        Bank's plan if it were not pre-existing), subject to deductibles
        and/or copayment provisions generally applicable to such coverage.

                  (d)  Subject to applicable law, OSB and FCB acknowledge and
        agree that the other shall be permitted to take whatever action it
        deems reasonably necessary to accelerate any deferred bonuses and to
        provide that all account balances, benefits accrued and options or
        awards previously granted under the Oshkosh Savings Bank Management
        Development and Recognition Plan ("OSB MRP"), OSB Option Plan, and
        FCB Option Plan shall be fully vested and nonforfeitable as of the
        Closing Date.  

                  (e)  At the Effective Time, FCB shall assume all of the
        obligations under the OSB MRP and OSB Option Plan, and all shares of
        OSB Common Stock owned by the OSB MRP, which have not been awarded,
        shall be canceled at or prior to the Effective Time.

             6.11 Severance for Certain Employees.  The Surviving Corporation
   will provide severance payments to employees of OSB and FCB and their
   respective Subsidiaries (other than employees whose severance benefits are
   provided for in written employment or severance agreements) whose
   employment is terminated within twelve (12) months after the Effective
   Date due to job reductions, in the amount set forth below.  The severance
   payments which would be provided would be computed as follows:

             Non-Officer -- one (1) week for each full year of service;
             maximum twelve (12) weeks and minimum three (3) weeks current
             salary; and

             Officer -- (as set forth in Schedule 6.11) two (2) weeks for
             each full year of service; maximum 26 weeks and minimum six (6)
             weeks current salary.

                  In computing such severance payments for each regular part-
        time employee, such employee's per week compensation shall be based
        on 1/52 of the actual number of hours worked by such employee in
        1996.

             6.12 Dividends.  After the date of this Agreement, each of FCB
   and OSB shall coordinate with the other the declaration of any dividends
   in respect of FCB Common Stock and OSB Common Stock and the record dates
   and payment dates relating thereto, it being the intention of the parties
   hereto that holders of FCB Common Stock or OSB Common Stock shall not
   receive two dividends, or fail to receive one dividend, for any quarter
   with respect to their shares of FCB Common Stock and/or OSB Common Stock
   and any shares of common stock of the Surviving Corporation any holder of
   OSB Common Stock receives in exchange therefor in the Merger. 
   Furthermore, after the Closing Date, the Board of Directors of the
   Surviving Corporation intends to declare and pay regular quarterly cash
   dividends at least equal to the rate of $0.18 per share of the Surviving
   Corporation common stock, subject to applicable laws and the business
   judgment of the Board of Directors.

             6.13 Post-Closing Stock Options.  It is the intention of the
   parties hereto that the Surviving Corporation shall, within 30 days after
   the Closing Date, cause non-tax-qualified stock options (exercisable for
   shares of the Surviving Corporation's common stock) to be granted to the
   following executive officers of the Surviving Corporation in the following
   amounts: Donald D. Parker, 10,000; James J. Rothenbach, 20,000; Phillip J.
   Schoofs, 7,500; Harold L. Hermansen, 6,000; and Theodore W. Hoff, 6,000. 
   The stock options provided for in this Section 6.13 shall be granted by
   the personnel committee of the Surviving Corporation under the terms of
   FCB's 1993 Stock Option and Incentive Plan.

             6.14 Subsidiary Bank Merger.  FCB and OSB agree to cooperate and
   to take such steps as may be necessary to obtain all requisite regulatory,
   corporate and other approvals for the Bank Merger, subject to consummation
   of the Merger, to be effective concurrently with the Merger or as soon as
   practicable thereafter.  The Surviving Bank shall be FCB Bank, and shall
   be known as "Fox Cities Bank, FSB."  In furtherance of such agreement,
   each of FCB and OSB agrees:

                  (a)  to cause the board of directors of FCB Bank and OSB
        Bank, respectively, to approve the Bank Merger and to submit it to

        consummate the Bank Merger concurrently with or as soon as is
        practicable after consummation of the Merger.

   The Bank Merger shall be accomplished pursuant to a merger agreement
   containing such terms and conditions as are ordinary and customary for
   affiliated bank merger transactions of such type.  Immediately after the
   Effective Time, the officers of the Surviving Corporation shall take, or
   cause to be taken, whatever additional steps may be necessary to
   effectuate the Bank Merger.  The directors and officers of the Surviving
   Bank shall be as set forth in the list attached as Exhibit E.

             6.15 Rule 145 Affiliates.  Within 30 days before the Closing
   Date, OSB shall identify in a letter to FCB all persons who are, and to
   OSB's knowledge who will be at the Closing Date, "affiliates" of OSB as
   such term is used in Rule 145 under the Securities Act.  OSB shall use all
   reasonable efforts to cause its affiliates (including any person who may
   be deemed to have become an affiliate after the date of the letter
   referred to in the prior sentence) to deliver to FCB on or prior to the
   Closing Date a written agreement substantially in the form attached hereto
   as Exhibit F.

             6.16 Disclosure Schedules.  On the date hereof,

                  (a)  FCB has delivered to OSB the FCB Disclosure Schedules,

   the SEC, the OTS or any State Regulatory Agency in connection with the
   Merger, the Bank Merger and the transactions contemplated by this

        received an opinion of their respective counsel, in form and
        substance reasonably satisfactory to each, dated as of the Effective

        tax free reorganization under Section 368(a)(1)(A) of the Internal
        Revenue Code and related sections of the Code.

        specific date or time other than the date hereof or the Closing Date
        which need only be true and correct as of such date or time) except
        in each of cases (i) and (ii) for such failures of representations or

        not, result in an FCB Material Adverse Effect.  OSB shall have
        received a certificate signed on behalf of FCB by the Chief Executive
        Officer and Chief Financial Officer of FCB to the foregoing effect.

                  (b)  Performance of Obligations of FCB.  FCB shall have
        performed in all material respects all obligations required to be

        received a certificate signed on behalf of FCB by the Chief Executive
        Officer and Chief Financial Officer of FCB to such effect.

                  (c)  No Material Adverse Change.  Since the date of this

        locations comparable to those of FCB or the FCB Subsidiaries), event,
        circumstances, fact or other occurrence shall have occurred that may

        Effect on FCB.

        received in the Merger by the shareholders of OSB is fair, from a
        financial point of view, to the shareholders of OSB.

             7.3  Conditions to Obligations of FCB.  The obligation of FCB to

        and warranties of OSB set forth in this Agreement shall be true and
        correct (i) on and as of the date hereof and (ii) on and as of the
        Closing Date with the same effect as though such representations and
        warranties had been made on and as of the Closing Date (except for
        representations and warranties that expressly speak only as of a
        specific date or time other than the date hereof or the Closing Date
        which need only be true and correct as of such date or time) except
        in each of cases (i) and (ii) for such failures of representations or
        warranties to be true and correct (without regard to any materiality
        qualifications contained therein) which, individually or in the
        aggregate do not, and insofar as reasonably can be foreseen, would
        not, result in an OSB Material Adverse Effect.  FCB shall have
        received a certificate signed on behalf of OSB by the Chief Executive
        Officer and Chief Financial Officer of OSB to the foregoing effect.

                  (b)  Performance of Obligations of OSB.  OSB shall have
        performed in all material respects all obligations required to be
        performed by it under this Agreement, the Plan of Merger and the

        received a certificate signed on behalf of OSB by the Chief Executive
        Officer and Chief Financial Officer of OSB to such effect.

                  (c)  No Material Adverse Change.  Since the date of this
        Agreement, (i) no event shall have occurred which has had a Material
        Adverse Effect on OSB, and (ii) no condition (other than general
        economic or competitive conditions generally affecting savings and
        loan holding companies and savings associations of a size or in
        locations comparable to those of OSB or the OSB Subsidiaries), event,
        circumstances, fact or other occurrence shall have occurred that may
        reasonably be expected to have or result in such a Material Adverse
        Effect on OSB.

                  (d)  Opinion of Counsel to OSB.  FCB shall have received

        FCB shareholders pursuant to the Merger is fair, from a financial
        point of view, to the shareholders of FCB.

                  (g)  Affiliate Agreements.  FCB shall have received

                       TERMINATION, EXPENSES AND AMENDMENT

             8.1  Termination.  This Agreement may be terminated prior to the
   Effective Time:

                  (a)  at any time, whether before or after approval of the
        matters presented in connection with the Merger by the shareholders
        of FCB or OSB, by written agreement between FCB or OSB, if the Board
        of Directors of each so determines; 

                  (b)  by FCB, by written notice to OSB, within twenty (20)
        days of the date of this Agreement, if, based on the information
        discovered in the course of its due diligence investigation of OSB
        and the OSB Subsidiaries, FCB reasonably determines in good faith 
        that the consummation of the transactions contemplated by this
        Agreement would not be in the best interests of FCB; provided,
        however, that FCB shall have ten (10) days in addition to the initial
        20-day period to terminate this Agreement pursuant to this Section
        8.1(b) if FCB determines, in good faith, based on the information
        discovered in its review of "Phase I" environmental audits of the
        real property owned by OSB and the OSB Subsidiaries, that the
        transactions contemplated by this Agreement would not be in the best
        interests of FCB; provided that such additional 10-day period shall
        not begin to run (following the initial twenty-day period) until such
        time as OSB has caused such Phase I audits to be delivered to FCB;

                  (c)  By OSB, by written notice to FCB, within twenty (20)
        days of the date of this Agreement, if, based on the information
        discovered in the course of its due diligence investigation of FCB
        and the FCB Subsidiaries, OSB reasonably determines in good faith 
        that the consummation of the transactions contemplated by this
        Agreement would not be in the best interests of OSB; provided,
        however, that OSB shall have ten (10) days in addition to the initial
        20-day period to terminate this Agreement pursuant to this Section
        8.1(c) if OSB determines, in good faith, based on the information
        discovered in its review of "Phase I" environmental audits of the
        real property owned by FCB and the FCB Subsidiaries, that the
        transactions contemplated by this Agreement would not be in the best
        interests of OSB; provided that such additional 10-day period shall
        not begin to run (following the initial twenty-day period) until such
        time as FCB has caused such Phase I audits to be delivered to OSB;

                  (d)  at any time, whether before or after approval of the
        matters presented in connection with the Merger by the shareholders
        of FCB or OSB, by either the Board of Directors of FCB or the Board
        of Directors of OSB if (i) any Governmental Entity which must grant a
        Requisite Regulatory Approval (A) has denied approval of the Merger
        and such denial has become final and nonappealable or (B) has advised
        the parties of its unwillingness to grant such a Requisite Regulatory
        Approval on terms and conditions reasonably acceptable to the
        parties, notwithstanding the parties' fulfillment of their
        obligations to take reasonable efforts to obtain such Requisite
        Regulatory Approval, or (ii) any Governmental Entity of competent
        jurisdiction shall have issued a final nonappealable order
        permanently enjoining or otherwise prohibiting the consummation of
        the transactions contemplated by this Agreement;

                  (e)  by either the Board of Directors of FCB or the Board
        of Directors of OSB if the Merger shall not have been consummated on
        or before September 30, 1997, unless the failure of the Closing to
        occur by such date shall be due to the failure of the party seeking
        to terminate this Agreement to perform or observe the covenants and
        agreements of such party set forth herein;

                  (f)  by either FCB or OSB if any approval of the
        shareholders of FCB or OSB required for the consummation of the
        Merger shall not have been obtained by reason of the failure to
        obtain the required vote at a duly held meeting of shareholders or at
        any adjournment or postponement thereof;

                  (g)  by OSB, upon two (2) days' prior notice to FCB, if, as
        a result of a tender offer by a party other than FCB or its
        affiliates or any written offer or proposal with respect to a merger,
        share exchange, sale of a material portion of its assets or other
        business combination (each, a "Business Combination") by a party
        other than FCB or its affiliates, the Board of Directors of OSB
        determines in good faith that its fiduciary obligations under
        applicable law require that such tender offer or other written offer
        or proposal be accepted; provided, however, that

                       (i)  the Board of Directors of OSB shall have been
             advised in a written opinion of outside counsel that
             notwithstanding a binding commitment to consummate an agreement
             of the nature of this Agreement entered into in the proper
             exercise of its applicable fiduciary duties, and notwithstanding
             all concessions which may be offered by FCB in negotiations
             entered into pursuant to clause (ii) below, such fiduciary
             duties would require the directors to reconsider such commitment
             as a result of such tender offer or other written offer or
             proposal; and

                       (ii) prior to any such termination, OSB shall, and
             shall cause its financial and legal advisors to, negotiate with
             FCB to make such adjustments in the terms and conditions of this
             Agreement as would enable OSB to proceed with the transactions
             contemplated herein on such adjusted terms;

                  (h)  by FCB, upon two (2) days' prior notice to OSB, if, as
        a result of a tender offer by a party other than OSB or its
        affiliates or any written offer or proposal with respect to a
        Business Combination by a party other than OSB or its affiliates, the
        Board of Directors of FCB determines in good faith that its fiduciary
        obligations under applicable law require that such tender offer or
        other written offer or proposal be accepted; provided, however, that

                       (i)  the Board of Directors of FCB shall have been
             advised in a written opinion of outside counsel that
             notwithstanding a binding commitment to consummate an agreement
             of the nature of this Agreement entered into in the proper
             exercise of its applicable fiduciary duties, and notwithstanding
             all concessions which may be offered by OSB in negotiations
             entered into pursuant to clause (ii) below, such fiduciary
             duties would require the directors to reconsider such commitment
             as a result of such tender offer or other written offer or
             proposal; and 

                       (ii) prior to any such termination, FCB shall, and
             shall cause its financial and legal advisors to, negotiate with
             OSB to make such adjustments in the terms and conditions of this
             Agreement as would enable FCB to proceed with the transactions
             contemplated herein on such adjusted terms;

                  (i)  by OSB, by written notice to FCB, if

                       (i)  there exists any breach or breaches of the
             representations and warranties of FCB made herein or in the FCB
             Stock Option Agreement, which breaches, individually or in the
             aggregate have or, insofar as reasonably can be foreseen, would
             have, a FCB Material Adverse Effect, and such breaches shall not
             have been remedied within thirty (30) days after receipt by FCB
             of notice in writing from OSB, specifying the nature of such
             breaches and requesting that they be remedied;

                       (ii) FCB shall have failed to perform and comply with,
             in all material respects, its agreements and covenants hereunder
             or under the FCB Stock Option Agreement and such failure to
             perform or comply shall not have been remedied within thirty
             (30) days after receipt by FCB of notice in writing from OSB,
             specifying the nature of such failure and requesting that it be
             remedied; or

                       (iii)     the Board of Directors of FCB or any
             committee thereof:

                            (A)  shall withdraw or modify in any manner
                  adverse to OSB its approval or recommendation of this
                  Agreement or the Merger,

                            (B)  shall fail to reaffirm such approval or
                  recommendation upon OSB's request,

                            (C)  shall approve or recommend any Business
                  Combination involving FCB other than the Merger or any
                  tender offer or share exchange for shares of capital stock
                  of FCB, in each case, by or involving a party other than
                  OSB or any of its affiliates or

                            (D)  shall resolve to take any of the actions
                  specified in clause (A), (B) or (C); or

                  (j)  by FCB, by written notice to OSB, if

                       (i)  there exists any breach or breaches of the
             representations and warranties of OSB made herein or in the OSB
             Stock Option Agreement which breaches, individually or in the
             aggregate have, or insofar as reasonably can be foreseen, would
             have, an OSB Material Adverse Effect and such breaches shall not
             have been remedied within thirty (30) days after receipt by OSB
             of notice in writing from FCB, specifying the nature of such
             breaches and requesting that they be remedied;

                       (ii) OSB shall have failed to perform and comply with,
             in all material respects, its agreements and covenants hereunder
             or under the OSB Stock Option Agreement and such failure to
             perform or comply shall not have been remedied within thirty
             (30) days after receipt by OSB of notice in writing from FCB,
             specifying the nature of such failure and requesting that it be
             remedied; or

                       (iii)     the Board of Directors of OSB or any
             committee thereof:

                            (A)  shall withdraw or modify in any manner
                  adverse to FCB its approval or recommendation of this
                  Agreement or the Merger,

                            (B)  shall fail to reaffirm such approval or
                  recommendation upon FCB's request,

                            (C)  shall approve or recommend any Business
                  Combination involving OSB other than the Merger involving
                  OSB or any tender offer or share exchange for shares of
                  capital stock of OSB, in each case, by or involving a party
                  other than FCB or any of its affiliates or

                            (D)  shall resolve to take any of the actions
                  specified in clause (A), (B) or (C).

             8.2  Effect of Termination.  Subject to Section 8.3, in the
   event of termination of this Agreement by OSB or FCB pursuant to Section
   8.1 there shall be no liability on the part of either OSB or FCB or their
   respective officers or directors hereunder, except that Section 6.2(b),
   Section 6.17, Section 8.2 and Section 8.3 shall survive the termination.

             8.3  Termination Fee; Expenses.  

                  (a)  Termination Fee Upon Breach or Willful Breach.  If
        this Agreement is terminated at such time that this Agreement is
        terminable pursuant to one (but not both) of (A) Section 8.1(i)(i) or
        (ii), or (B) Section 8.1(j)(i) or (ii) then:

                       (i)  the breaching party shall promptly (but no later
             than five (5) business days after receipt of notice from the
             non-breaching party) pay to the non-breaching party in cash an
             amount equal to all documented out-of-pocket expenses and fees
             incurred by the non-breaching party (including, without
             limitation, fees and expenses payable to all legal, accounting,
             financial, public relations and other professional advisors
             arising out of, in connection with or related to the Merger or
             the transactions contemplated by this Agreement) not in excess
             of $200,000; provided, however, that, if this Agreement is
             terminated by a party as a result of a willful breach by other
             party, the non-breaching party may pursue any remedies available
             to it at law or in equity and shall, in addition to its
             documented out-of-pocket expenses and fees (which shall be paid
             as specified above and shall not be limited to $200,000), be
             entitled to recover such additional amounts as such non-
             breaching party may be entitled to receive at law or in equity;
             and

                       (ii) if at the time of the breaching party's willful
             breach of this Agreement, there shall have been a third party
             tender offer for shares of, or a third party offer or proposal
             with respect to a Business Combination involving, such party, or
             any of its affiliates which at the time of such termination
             shall not have been rejected by such party and its board of
             directors or withdrawn by the third party,

        then such breaching party (jointly and severally with its
        affiliates), at the time of the termination of this Agreement, will
        pay to the non-breaching party an additional aggregate fee equal to
        $1 million.

                  (b)  Alternative Termination Fee.  If

                       (i)  this Agreement

                            (A)  is terminated by any party pursuant to
                  Section 8.1(g) or (h), 

                            (B)  is terminated as a result of any party's
                  material breach of Section 6.3,

                            (C)  is terminated pursuant to Section 8.1(f)
                  following a failure of shareholders of OSB or FCB to grant
                  the necessary approvals described in Section 3.23 or
                  Section 4.23, as the case may be (a "Shareholder
                  Disapproval"), or

                            (D)  is terminated pursuant to one (but not both)
                  of Section 8.1(i)(iii) or Section 8.1(j)(iii), and

                       (ii) with respect to any termination referred to in
             clause (i)(A), (B) or (C) above, at the time of such termination
             (or prior to the meeting at which such Shareholder Disapproval
             occurred), there shall have been a third-party tender offer for
             shares of, or a third-party offer or proposal with respect to a
             Business Combination involving, OSB or FCB (as the case may be,
             the "Target Party") or any affiliates thereof which at the time
             of such termination or of the meeting of the Target Party's
             shareholders, as the case may be, shall not have been withdrawn
             by the third-party,

        then such Target Party (jointly and severally with its affiliates),
        at the time of the termination of this Agreement, will pay to the
        other party in cash an aggregate termination fee equal to $1 million,
        plus, in each case, the documented out-of-pocket fees and expenses
        incurred by the other party (including, without limitation, fees and
        expenses payable to all legal, accounting, financial, public
        relations and other professional advisors arising out of, in
        connection with or related to the Merger or the transactions
        contemplated by this Agreement).

                  (c)  Expenses.  The parties agree that the agreements
        contained in this Section 8.3 are an integral part of the
        transactions contemplated by this Agreement and constitute liquidated
        damages and not a penalty.  If one party fails to promptly pay to any
        other party any fee due hereunder, the defaulting party shall pay the
        costs and expenses (including legal fees and expenses) in connection
        with any action, including the filing of any lawsuit or other legal
        action, taken to collect payment, together with interest on the
        amount of any unpaid fee at the publicly announced prime rate as
        published in the Wall Street Journal (Midwest Edition) from the date
        such fee was required to be paid.

                  (d)  Limitation on Termination Fees.  Notwithstanding
        anything herein to the contrary:

                       (i)  the aggregate amount payable by OSB and its
             affiliates to FCB pursuant to Section 8.3(a), Section 8.3(b) and
             the terms of the OSB Stock Option Agreement shall not exceed
             $1.5 million, and

                       (ii) the aggregate amount payable by FCB and its
             affiliates to OSB pursuant to Section 8.3(a), Section 8.3(b) and
             the terms of the FCB Stock Option Agreement shall not exceed
             $1.5 million.

        (exclusive, in each case, of reimbursement for fees and expenses
        payable pursuant to this Section 8.3).  For purposes of this Section
        8.3(d), the amount payable pursuant to the terms of the Option
        Agreements shall be the amount paid pursuant to Section 5 and/or
        Section 8(a)(i) and Section 8(1)(ii) thereof. 

             8.4  Amendment.  Subject to compliance with applicable law, this
   Agreement may be amended by the parties hereto, by action taken or
   authorized by their respective Boards of Directors, at any time before or
   after approval of the matters presented in connection with the Merger by
   the shareholders of FCB or OSB; provided, however, that after any approval
   of the transactions contemplated by this Agreement by the respective
   shareholders of FCB or OSB, there may not be, without further approval of
   such shareholders, any amendment of this Agreement which changes the
   amount or the form of the consideration to be delivered to the holders of
   FCB Common Stock or OSB Common Stock hereunder other than as contemplated
   by this Agreement.  This Agreement may not be amended except by an
   instrument in writing signed on behalf of each of the parties hereto.

             8.5  Extension; Waiver. At any time prior to the Effective Time,
   the parties hereto, by action taken or authorized by their respective
   Board of Directors, may, to the extent legally allowed, (a) extend the
   time for the performance of any of the obligations or other acts of the
   other parties hereto, (b) waive any inaccuracies in the representations
   and warranties contained herein or in any document delivered pursuant
   hereto, and (c) waive compliance with any of the agreements or conditions
   contained herein; provided, however, that after any approval of the
   transactions contemplated by this Agreement by the respective shareholders
   of FCB or OSB, there may not be, without further approval of such
   shareholders, any extension or waiver of this Agreement or any portion
   thereof which reduces the amount or changes the form of the consideration
   to be delivered to the holders of FCB Common Stock or OSB Common Stock
   hereunder other than as contemplated by this Agreement.  Any agreement on
   the part of a party hereto to any such extension or waiver shall be valid
   only if set forth in a written instrument signed on behalf of such party,
   but such extension or waiver or failure to insist on strict compliance
   with an obligation, covenant, agreement or condition shall not operate as
   a waiver of, or estoppel with respect to, any subsequent or other failure.

   to this Agreement, which shall terminate in accordance with its terms)
   shall survive the Effective Time, except for those covenants and
   agreements contained herein and therein which by their terms apply in
   whole or in part after the Effective Time.  Without by implication
   limiting the foregoing, none of the directors or officers of the parties
   hereto shall have any liability for any of the representations,
   warranties, covenants and agreements contained herein.

   to Sections, Exhibits or Schedules, such reference shall be to a section
   of or exhibit or schedule to this Agreement unless otherwise indicated. 
   The table of contents and headings contained in this Agreement are for
   reference purposes only and shall not affect in any way the meaning or
   interpretation of this Agreement.  Whenever the words "include,"
   "includes" or "including" are used in this Agreement, they shall be deemed
   to be followed by the words "without limitation."  No provision of this
   Agreement shall be construed to require OSB, the OSB Subsidiaries, FCB or
   the FCB Subsidiaries or affiliates to take any action which would violate
   any applicable law, rule or regulation.

             9.4  Counterparts.  This Agreement may be executed in
   counterparts, all of which shall be considered one and the same agreement
   and shall become effective when counterparts have been signed by each of
   the parties and delivered to the other parties, it being understood that
   all parties need not sign the same counterpart.

             9.5  Entire Agreement.  This Agreement (including the documents
   and the instruments referred to herein) constitutes the entire agreement
   and supersedes all prior agreements and understandings, both written and
   oral, among the parties hereto with respect to the subject matter hereof.

   State of Wisconsin, without regard to any applicable conflicts of law.

             9.7  Severability.  Any term or provision of this Agreement
   which is invalid or unenforceable in any jurisdiction shall, as to that
   jurisdiction, be ineffective to the extent of such invalidity or
   unenforceability without rendering invalid or unenforceable the remaining
   terms and provisions of this Agreement or affecting the validity or
   enforceability of any of the terms or provisions of this Agreement in any
   other jurisdiction.  If any provision of this Agreement is so broad as to
   be unenforceable, the provision shall be interpreted to be only so broad
   as is enforceable.

             9.8  Publicity.  Except as otherwise required by applicable law
   or the rules of The Nasdaq Stock Market, neither OSB nor FCB shall, nor
   shall OSB or FCB permit the OSB Subsidiaries or the FCB Subsidiaries,

   hereto any rights or remedies hereunder.

             9.10 Enforcement.  The parties agree that irreparable damage
   would occur in the event that any of the provisions of this Agreement were
   not performed in accordance with their specific terms or were otherwise
   breached.  It is accordingly agreed that the parties shall be entitled to

                                                               Execution Copy

             STOCK OPTION AND TRIGGER PAYMENT AGREEMENT (the "Agreement"),
   dated November 13, 1996, between FCB Financial Corp., a Wisconsin
   corporation ("Issuer"), and OSB Financial Corp., a Wisconsin corporation
   ("Grantee").


                              W I T N E S S E T H:


             WHEREAS, Grantee and Issuer have entered into an Agreement and
   Plan of Merger of even date herewith (the "Merger Agreement"), which
   agreement has been executed by the parties hereto immediately prior to
   this Stock Option and Trigger Agreement; and

             WHEREAS, as a condition to Grantee's entering into the Merger
   Agreement and in consideration therefor, Issuer has agreed to grant
   Grantee the Option (as hereinafter defined).

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

        1.   (a)  Issuer hereby grants to Grantee an unconditional,
   irrevocable option (the "Option") to purchase, subject to the terms
   hereof, up to 489,463 fully paid and nonassessable (except as otherwise
   provided by Section 180.0622(2)(b) of the Wisconsin Business Corporation
   Law) shares (the "Option Shares") of Issuer's Common Stock, par value
   $0.01 per share ("Issuer Common Stock"), at a price of $18.875 per share
   (the "Option Price"); provided, however, that in no event shall the number
   of shares of Issuer Common Stock for which this Option is exercisable
   exceed 19.9% of the issued and outstanding shares of Issuer Common Stock
   without giving effect to any shares subject to or issued pursuant to the
   Option.  The number of shares of Issuer 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 Issuer Common
   Stock are either (i) issued or otherwise become outstanding after the date
   of this Agreement (other than pursuant to this Agreement) or (ii)
   redeemed, repurchased, retired or otherwise cease to be outstanding after
   the date of this Agreement (such event a "Change in Shares Outstanding
   Event"), the number of shares of Issuer Common Stock subject to the Option
   shall be increased or decreased, as appropriate, so that, after such
   Change in Shares Outstanding Event, such number equals 19.9% of the number
   of shares of Issuer Common Stock then issued and outstanding without
   giving effect to any shares subject or issued pursuant to the Option. 
   Nothing contained in this Section 1(b) or elsewhere in this Agreement
   shall be deemed to authorize Issuer to issue or redeem, repurchase, or
   retire shares of Issuer Common Stock or to authorize either the Issuer or
   the Grantee otherwise to breach any provision of the Merger Agreement.

             (c)  The Option Price shall be payable, at the option of the
   Grantee, as follows:

                  (i)  in cash, or

                  (ii) subject to the receipt of all approvals of any
   Governmental Entity required for the Issuer to acquire, and Grantee to
   issue, the Grantee Shares (as defined below) from Grantee, in shares of
   common stock, $0.01 par value, of Grantee ("Grantee Shares"),

   in either case in accordance with Section 4 hereof.

             (d)  As used in this Agreement, the "Fair Market Value" of any
   share shall be the average of the last sales price for such share on The
   Nasdaq Stock Market during the ten trading days prior to the fifth trading
   day preceding the date such Fair Market Value is to be determined.

        2.   (a)  The Option may be exercised by Grantee, in whole or in
   part, at any time or from time to time after the Merger Agreement becomes
   terminable by Grantee under circumstances which could entitle Grantee to a
   termination fee (as opposed to the reimbursement of expenses only) under
   Section 8.3(a) of the Merger Agreement or Section 8.3(b) of the Merger
   Agreement (regardless of whether the Merger Agreement is actually
   terminated), any such event by which the Merger Agreement becomes so
   terminable by Grantee being referred to herein as a " Trigger Event."

             (b)  (i)  Issuer shall notify Grantee promptly in writing of the
   occurrence of any Trigger Event, it being understood that the giving of
   such notice by Issuer shall not be a condition to the right of Grantee to
   exercise the Option.

                  (ii) In the event Grantee wishes to exercise the Option,
   Grantee shall deliver to Issuer written notice (an "Exercise Notice")
   specifying the total number of Option Shares it wishes to purchase.

                  (iii)     Upon the giving by Grantee of Issuer of the
   Exercise Notice and the tender of the applicable aggregate Option Price,
   Grantee, to the extent permitted by law and Issuer's organizational
   documents, and provided that the conditions to Issuer's obligation to
   issue Option Shares to Grantee hereunder set forth in Section 3 have been
   satisfied or waived, shall be deemed to be the holder of record of the
   Option Shares issuable upon such exercise, notwithstanding that the stock
   transfer books of Issuer shall then be closed or that certificates
   representing such Option Shares shall not then be actually delivered to
   Grantee.

                  (iv) Each closing of a purchase of Option Shares (a
   "Closing") shall occur at a place, on a date, and at a time designated by
   Grantee in an Exercise Notice delivered at least two business days prior
   to the date of the Closing.

             (c)  The Option shall terminate upon the earliest to occur of:

                  (i)  the Effective Time of the Merger;

                  (ii) the termination of the Merger Agreement pursuant to
   Section 8.1 thereof, other than under circumstances which also constitute
   a Trigger Event under this Agreement;

                  (iii)     180 days following any termination of the Merger
   Agreement upon or during the continuance of a Trigger Event (or if, at the
   expiration of such 180-day period, the Option cannot be exercised by
   reason of any applicable judgment, decree, order, law or regulation, ten
   business days after such impediment to exercise shall have been removed or
   shall have become final and not subject to appeal, but in no event under
   this clause (iii) later than September 30, 1997); and

                  (iv) payment by Issuer of the Trigger Payment set forth in
   Section 5 of this Agreement to Grantee.

             (d)  Notwithstanding the foregoing, the Option may not be
   exercised if (i) Grantee is in material breach of any of its
   representations or warranties, or in material breach of any of its
   covenants or agreements, contained in this Agreement or in the Merger
   Agreement, or (ii) a Trigger Payment has been paid pursuant to Section 5
   of this Agreement or demand therefor has been made and not withdrawn.

        3.   The obligation of Issuer to issue Option Shares to Grantee
   hereunder is subject to the conditions that

             (a)  the Option Shares, and any Grantee Shares which are issued
   in payment of the Option Price, shall have been approved for listing on
   The Nasdaq Stock Market;

             (b)  all consents, approvals, orders or authorizations of, or
   registrations, declarations or filings with, any federal, state or local
   administrative agency or commission or other federal, state or local
   Governmental Entity, if any, required in connection with the issuance by
   Issuer and the acquisition by Grantee of the Option Shares hereunder shall
   have been obtained or made; and

             (c)  no preliminary or permanent injunction or other order by
   any court of competent jurisdiction prohibiting or otherwise restraining
   such issuance shall be in effect.

   The condition set forth in paragraph (a) above may be waived by Issuer, in
   the case of Grantee Shares, and by Grantee, in the case of Option Shares,
   in the sole discretion of the waiving party.

        4.   At any Closing,

             (a)  Issuer shall deliver to Grantee or its designee a single
   certificate in definitive form representing the number of Option Shares
   designated by Grantee in its Exercise Notice, such certificate to be
   registered in the name of Grantee and to bear the legend set forth in
   Section 13; and 

             (b)  Grantee shall deliver to issuer the aggregate price for the
   Option Shares so designated and being purchased by

                  (i)  wire transfer of immediately available funds or
   certified check or bank check, or

                  (ii) subject to the condition in Section 1(c)(ii), delivery
   of a certificate or certificates representing the number of Grantee Shares
   being issued by Grantee in consideration thereof, determined in accordance
   with Section 4(c).

             (c)  In the event that Grantee issues Grantee Shares to Issuer
   in consideration of Option Shares pursuant to Section 4(b)(ii), the number
   of Grantee Shares to be so issued shall be equal to the quotient obtained
   by dividing:

                  (i)  the product of (x) the number of Option Shares with
   respect to which the Option is being exercised and (y) the Option Price,
   by

                  (ii) the Fair Market Value of the Grantee Shares as of the
   date immediately preceding the date the Exercise Notice is delivered to
   Issuer.

             (d)  Issuer shall pay all expenses, and any and all 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 4.

        5.   (a)  Subject to the provisions of Section 8.3(d) of the Merger
   Agreement, if a Trigger Event shall have occurred and any regulatory
   approval or order required for the issuance by Issuer, or the acquisition
   by Grantee, of the Option or the Option Shares upon exercise of the Option
   shall not have been obtained, Grantee shall have the right to receive, and
   Issuer shall pay to Grantee, an amount (the "Trigger Payment") equal to
   the product of

                  (i)  the maximum number of Option Shares that would have
   been subject to purchases by Grantee upon exercise of the Option pursuant
   to Sections 1 and 2 hereof if all such regulatory approvals or orders had
   been obtained, and

                  (ii) the difference between (A) the Market/Offer Price (as
   defined herein), determined as of the date on which notice of demand for
   the Trigger Payment is given by Grantee, and (B) the Option Price (but
   only if such Market/Offer Price is higher than such Option Price).

   Demand for the Trigger Payment shall be given by notice in accordance with
   the provisions of Section 17 hereof.  The Trigger Payment shall be paid to
   Grantee by Issuer on the Payment Date (as defined herein), by wire
   transfer or immediately available funds to an account to be designated in
   writing by Grantee not less than two business days before the Payment
   Date.

             (b)  For purposes of this Section 5, "Payment Date" means the
   date on which termination fees are required to be paid by Issuer to
   Grantee under Sections 8.3(a) or 8.3(b), as the case may be, of the Merger
   Agreement as a result of the occurrence of the Trigger Event referred to
   in subsection (a) of this Section 5 or such later date as Grantee shall
   specify with two business days prior written notice to Issuer.

             (c)  Issuer shall have no obligation to pay the Trigger Payment
   if Grantee is in material breach of any of its representations or
   warranties, or in material breach of any of its covenants or agreements,
   contained in this Agreement or in the Merger Agreement.

        6.   Issuer represents and warrants to Grantee that

             (a)  Issuer has the corporate power and authority to enter into
   this Agreement and to carry out its obligations hereunder, subject in the
   case of the repurchase of the Option Shares pursuant to Section 8(a) to
   applicable law;

             (b)  this Agreement has been duly and validly executed and
   delivered by Issuer, and, assuming the due authorization, execution and
   delivery hereof by Grantee and the receipt of all required regulatory
   approvals, constitutes a valid and binding obligation of Issuer,
   enforceable against Issuer in accordance with its terms;

             (c)  Issuer has taken all necessary corporate action to
   authorize and reserve for issuance and to permit it to issue, upon
   exercise of the Option, and at all times from the date hereof through the
   expiration of the Option will have reserved, the number of authorized and
   unissued Option Shares, such amount being subject to adjustment as
   provided in Sections 1 and 12, all of which, upon their issuance and
   delivery in accordance with the terms of this Agreement, will be duly
   authorized, validly issued, fully paid and nonassessable (except as
   otherwise provided by Section 180.0622(2)(b) of the Wisconsin Business
   Corporation Law);

             (d)  upon delivery of the Option Shares to Grantee upon the
   exercise of the Option, Grantee will acquire the Option Shares free and
   clear of all claims, liens, charges, encumbrances and security interests
   of any nature whatsoever;

             (e)  except as described in Section 4.4 of the Merger Agreement,
   the execution and delivery of this Agreement by Issuer does not, and,
   subject to compliance with applicable law with respect to the repurchase
   of the Option Shares pursuant to Section 8(a), the consummation by Issuer
   of the transactions contemplated hereby will not, violate, conflict with,
   or result in a breach of any provision of, or constitute a default (with
   or without notice or a lapse of time, or both) under, or result in the
   termination of, or accelerate the performance required by, or result in a
   right of termination, cancellation, or acceleration of any obligation or
   the loss of a material benefit under, or the creation of a lien, pledge,
   security interest or other encumbrance on assets (any such conflict,
   violation, default, right of termination, cancellation, acceleration, loss
   or creation, hereinafter a "Violation") of Issuer or any of its
   Subsidiaries, pursuant to

                  (i)  any provision of the Articles of Incorporation or the
   Bylaws of Issuer,

                  (ii) any provisions of any material loan or credit
   agreement, note, mortgage, indenture, lease, benefit plan or other
   agreement, obligation, instrument, permit, concession, franchise or
   license (any of the foregoing in effect on the date hereof being referred
   to as a "Material Contract") of Issuer or its Subsidiaries or to which any
   of them is a party, or

                  (iii)     any judgment, order, decree, statute, law,
   ordinance, rule or regulation applicable to Issuer or its properties or
   assets,

   which Violation, in the case of each clauses (ii) and (iii), could
   reasonably be expected to have a Material Adverse Effect on Issuer (except
   that no representation or warranty is given concerning any Violation of a
   Material Contract with respect to the repurchase of Option Shares pursuant
   to Section 8(a));

             (f)  except as described in Section 4.4 of the Merger Agreement,
   the execution and delivery of this Agreement by Issuer does not, and the
   performance of this Agreement by Issuer will not, require any consent,
   approval, authorization or permit of, filing with or notification to, any
   Governmental Entity;

             (g)  none of Issuer, any of its affiliates or anyone acting on
   its or their behalf, has issued, sold or offered any security of Issuer to
   any person under circumstances that would cause the issuance and sale of
   the Option Shares, as contemplated by this Agreement, to be subject to the
   registration requirements of the Securities Act of 1933, as amended (the
   "Securities Act"), as in effect on the date hereof, and, assuming the
   representations and warranties of Grantee contained in Section 7(g) are
   true and correct, the issuance, sale and delivery of the Option Shares
   hereunder would be exempt from the registration and prospectus delivery
   requirements of the Securities Act, as in effect on the date hereof (and
   Issuer shall not take any action which would cause the issuance, sale, and
   delivery of the Option Shares hereunder not to be exempt from such
   requirements); and

             (h)  any Grantee Shares acquired pursuant to this Agreement will
   be acquired for Issuer's own account, for investment purposes only, and
   will not be acquired by Issuer with a view to the public distribution
   thereof in violation of any applicable provision of the Securities Act.

        7.   Grantee represents and warrants to Issuer that

             (a)  Grantee has the corporate power and authority to enter into
   this Agreement and to carry out its obligations hereunder;

             (b)  this Agreement has been duly and validly executed and
   delivered by Grantee and, assuming the due authorization, execution and
   delivery hereof by Issuer and the receipt of all required regulatory
   approvals, constitutes a valid and binding obligation of Grantee,
   enforceable against Grantee in accordance with its respective terms;

             (c)  prior to any delivery of Grantee Shares in consideration of
   the purchase of Option Shares pursuant hereto, Grantee will have taken all
   necessary corporate action to authorize for issuance and to permit it to
   issue such Grantee Shares, all of which, upon their issuance and delivery
   in accordance with the terms of this Agreement, will be duly authorized,
   validly issued, fully paid and nonassessable (except as otherwise provided
   in Section 180.0622(2)(b) of the Wisconsin Business Corporation Law);

             (d)  upon any delivery of such Grantee Shares to Issuer in
   consideration of the purchase of the Option Shares pursuant hereto, Issuer
   will acquire the Grantee Shares free and clear of all claims, liens,
   charges, encumbrances and security interests of any nature whatsoever;

             (e)  except as described in Section 3.4 of the Merger Agreement,
   the execution and delivery of this Agreement by Grantee does not, and the
   consummation by Grantee of the transactions contemplated hereby will not,
   violate, conflict with, or result in the breach of any provision of, or
   constitute a default (with or without notice or a lapse of time, or both)
   under, or result in any Violation by Grantee or any of its Subsidiaries,
   pursuant to

                  (i)  any provision of the Articles of Incorporation or
   Bylaws of Grantee,

                  (ii) any Material Contract of Grantee or any of its
   Subsidiaries or to which any of them is a party, or

                  (iii)     any judgment, order, decree, statute, law,
   ordinance, rule or regulation applicable to Grantee or its properties or
   assets,

   which Violation, in the case of each of clauses (ii) or (iii), would have
   a Material Adverse Effect on Grantee;

             (f)  except as described in Section 3.4 of the Merger Agreement,
   the execution and delivery of this Agreement by Grantee does not, and the
   consummation by Grantee of the transactions contemplated hereby will not,
   require any consent, approval, authorization or permit of, filing with or
   notification to, any Governmental Entity; and

             (g)  any Option Shares acquired upon exercise of the Option will
   be acquired for Grantee's own account, for investment purposes only and
   will not be, and the Option is not being, acquired by Grantee with a view
   to the public distribution thereof, in violation of any applicable
   provision of the Securities Act.

        8.   (a)  At the request of Grantee by written notice (x) at any time
   during which the Option is exercisable pursuant to Section 2 (the
   "Repurchase Period"), Issuer (or any successor entity thereof) shall, if
   permitted by applicable law, the Articles of Incorporation and Bylaws of
   the Issuer and Issuer's Material Contracts, repurchase from Grantee all or
   any portion of the Option, at the price set forth in subparagraph (i)
   below, or, (y) at any time prior to September 30, 1997, Issuer (or any
   successor entity thereof) shall, if permitted by applicable law, the
   Articles of Incorporation and Bylaws of Issuer and Issuer's Material
   Contracts, repurchase from Grantee all or any portion of the Option Shares
   purchased by Grantee pursuant to the Option, at the price set forth in
   subparagraph (ii) below:

                  (i)  (A)  The difference between the "Market/Offer Price"
   (as defined below) for shares of Issuer Common Stock as of the date
   Grantee gives notice of its intent to exercise its rights under this
   Section 8 and the Option Price, multiplied by the number of Option Shares
   purchasable pursuant to the Option (or portion thereof with respect to
   which Grantee is exercising its rights under this Section 8), but only if
   the Market/Offer Price is greater than the Option Price.

                       (B)  For purposes of this Agreement, "Market/Offer
   Price" shall mean, as of any date, the higher of (I) the price per share
   offered as of such date pursuant to any tender or exchange offer or other
   offer with respect to a Business Combination involving Issuer as the
   Target Party which was made prior to such date and not terminated or
   withdrawn as of such date and (II) the Fair Market Value per share of
   Issuer Common Stock as of such date.

                  (ii) (A)  The product of (I) the sum of (a) the Option
   Price paid by Grantee per Option Share acquired pursuant to the Option,
   and (b) the difference between the "Offer Price" (as defined below) and
   the Option Price, but only if the Offer Price is greater than the Option
   Price, and (II) the number of Option Shares so to be repurchased pursuant
   to this Section 8.

                       (B)  For purposes of this clause (ii), the "Offer
   Price" shall be the highest price per share offered pursuant to a tender
   or exchange offer or other Business Combination offer involving Issuer as
   the Target Party during the Repurchase Period prior to the delivery by
   Grantee of a notice of repurchase.

             (b)  If Grantee shall have previously elected to purchase Option
   Shares pursuant to the exercise of the Option by the issuance and delivery
   of Grantee Shares, then Issuer shall, if so requested by Grantee, in
   fulfillment of its obligation pursuant to Section 8(a)(y) (that is, with
   respect to the Option Price only and without limitation to its obligation
   to pay additional consideration under clause (b) of Section
   8(a)(ii)(A)(I)), redeliver the certificates for such Grantee Shares to
   Grantee, free and clear of all liens, claims, charges and encumbrances of
   any kind or nature whatsoever; provided, however, that if at any time less
   than all of the Option Shares so purchased by Grantee pursuant to the
   Option are to be repurchased by Issuer pursuant to Section 8(a)(y), then
   (i) Issuer shall be obligated to redeliver to Grantee the same proportion
   of such Grantee Shares as the number of Option Shares that Issuer is then
   obligated to repurchase bears to the number of Option Shares acquired by
   Grantee upon exercise of the Option and (ii) Grantee shall issue to Issuer
   new certificates representing those Grantee Shares which are not due to be
   redelivered to Grantee pursuant to this Section 8(b) to the extent that
   excess Grantee Shares are included in the certificates redelivered to
   Grantee by Issuer.

             (c)  In the event Grantee exercises its rights under this
   Section 8, Issuer shall, within ten business days thereafter, pay the
   required amount to Grantee in immediately available funds and Grantee
   shall surrender to Issuer the Option or the certificate or certificates
   evidencing the Option Shares purchased by Grantee pursuant hereto, and
   Grantee shall warrant that it owns the Option or such shares and that the
   Option or such shares are then free and clear of all liens, claims,
   damages, charges and encumbrances of any kind or nature whatsoever.

             (d)  If Grantee has elected to purchase Option shares pursuant
   to the exercise of the Option by the issuance and delivery of Grantee
   Shares, notwithstanding that Grantee may no longer hold any such Option
   Shares or that Grantee elects not to exercise its other rights under this
   Section 8, Grantee may require, at any time or from time to time prior to
   September 30, 1997, Issuer to sell to Grantee any such Grantee Shares at
   the price attributed to such Grantee Shares pursuant to Section 4 plus
   interest at the publicly announced prime rate as published in the Wall
   Street Journal (Midwest Edition) on such amount from the Closing Date
   relating to the exchange of such Grantee shares pursuant to Section 4 to
   the Closing Date under this Section 8(d) less any dividends on such
   Grantee Shares paid during such period or declared and payable to
   shareholders of record on a date during such period.

             (e)  In the event the repurchase price specified in Section 8(a)
   would subject the purchase of the Option or the Option Shares purchased by
   Grantee pursuant to the Option to a vote of the shareholders of Issuer
   pursuant to applicable law or the Articles of Incorporation of Issuer,
   then Grantee may, at its election, reduce the repurchase price to an
   amount which would permit such repurchase without the necessity for such a
   shareholder vote.

        9.   Following the date hereof and prior to the fifth anniversary of
   the date hereof (the "Expiration Date"), each party shall vote any shares
   of capital stock of the other party acquired by such party pursuant to
   this Agreement ("Restricted Shares"), including any Grantee Shares issued
   pursuant to Section 1(c), or otherwise beneficially owned (within the
   meaning of Rule 13d-3 promulgated under the Securities Exchange Act of
   1934, as amended (the "Exchange Act")), by such party on each matter
   submitted to a vote of shareholders of such other party for and against
   such matter in the same proportion as the vote of all other shareholders
   of such other party are voted (whether by proxy or otherwise) for and
   against such matter.

        10.  (a)  Prior to the Expiration Date, neither party shall, directly
   or indirectly, sell, assign, pledge, or otherwise dispose of or transfer
   any Restricted Shares beneficially owned by such party, other than (i)
   pursuant to Section 8, or (ii) in accordance with Section 10(b) or
   Section 11.

             (b)  Following the termination of the Merger Agreement, a party
   shall be permitted to sell any Restricted Shares beneficially owned by it
   if such sale is made pursuant to a tender or exchange offer that has been
   approved or recommended, or otherwise determined to be fair to and in the
   best interests of the shareholders of the other party, by a majority of
   the members of the Board of Directors of such other party, which majority
   shall include a majority of directors who were directors prior to the
   announcement of such tender or exchange offer.

        11.  (a)  Following the termination of the Merger Agreement, either
   party hereto that owns Restricted Shares (a "Designated Holder") may by
   written notice (the "Registration Notice") to the other party (the
   "Registrant") request the Registrant to register under the Securities Act
   all or any part of the Restricted Shares beneficially owned by such
   Designated Holder (the "Registrable Securities") pursuant to a bona fide
   firm commitment underwritten public offering, in which the Designated
   Holder and the underwriters shall effect as wide a distribution of such
   Registrable Securities as is reasonably practicable and shall use their
   best efforts to prevent any person (including any Group (as used in Rule
   13d-5 under the Exchange Act)) and its affiliates from purchasing through
   such offering Restricted Shares representing more than 1% of the
   outstanding shares of common stock of the Registrant on a fully diluted
   basis (a "Permitted Offering").

             (b)  The Registration Notice shall include a certificate
   executed by the Designated Holder and its proposed managing underwriter,
   which underwriter shall be an investment banking firm of recognized
   standing on a national or regional basis (the "Manager"), stating that

                  (i)  they have a good faith intention to commence promptly
   a Permitted Offering, and

                  (ii) Manager in good faith believes that, based on the
   then-prevailing market conditions, it will be able to sell the Registrable
   Securities at a per share price equal to at least 80% of the then Fair
   Market Value of such shares.

             (c)  The Registrant (and/or any person designed by the
   Registrant) shall thereupon have the option exercisable by written notice
   delivered to the Designated Holder within ten business days after the
   receipt of the Registration Notice, irrevocably to agree to purchase all
   or any part of the Registrable Securities proposed to be so sold for cash
   at a price equal to the product of (i) the number of Registrable
   Securities to be so purchased by the Registrant and (ii) the then Fair
   Market Value of such shares.

             (d)  Any purchase of Registrable Securities by the Registrant
   (or its designee) under Section 11(c) shall take place at a closing to be
   held at the principal executive offices of the Registrant or at the
   offices of its counsel at any reasonable date and time designated by the
   Registrant and/or such designee in such notice within twenty business days
   after delivery of such notice, and any payment for the shares to be so
   purchased shall be made by delivery at the time of such closing in
   immediately available funds.

             (e)  If the Registrant does not elect to exercise its option
   pursuant to this Section 11 with respect to all Registrable Securities, it
   shall use its best efforts to effect, as promptly as practicable, the
   registration under the Securities Act of the unpurchased Registrable
   Securities proposed to be so sold; provided, however, that

                  (i)  neither party shall be entitled to demand more than an
   aggregate of two effective registration statements hereunder, and

                  (ii) the Registrant will not be required to file any such
   registration statement during any period of time (not to exceed 40 days
   after such request in the case of clause (A) below or 90 days in the case
   of clauses (B) and (C) below) when

                       (A)  the Registrant is in possession of material non-
   public information which it reasonably believes would be detrimental to be
   disclosed at such time and, in the opinion of counsel to the Registrant,
   such information would be required to be disclosed if a registration
   statement were filed at that time;

                       (B)  the Registrant is required under the Securities
   Act to include audited financial statements for any period in such
   registration statement and such financial statements are not yet available
   for inclusion in such registration statement; or 

                       (C)  the Registrant determines, in its reasonable
   judgment, that such registration would interfere with any financing,
   acquisition or other material transaction involving the Registrant or any
   of its affiliates.

             (f)  The Registrant shall use its reasonable best efforts to
   cause any Registrable Securities registered pursuant to this Section 11 to
   be qualified for sale under the securities or Blue Sky laws of such
   jurisdictions as the Designated Holder may reasonably request and shall
   continue such registration or qualification in effect in such
   jurisdiction; provided, however, that the Registrant shall not be required
   to qualify to do business in, or consent to general service of process in,
   any jurisdiction by reason of this provision.

             (g)  The registration rights set forth in this Section 11 are
   subject to the condition that the Designated Holder shall provide the
   Registrant with such information with respect to such holder's Registrable
   Securities, the plans for the distribution thereof, and such other
   information with respect to such holder as, in the reasonable judgment of
   counsel for the Registrant, is necessary to enable the Registrant to
   include in such registration statement all material facts required to be
   disclosed with respect to a registration thereunder.

             (h)  A registration effected under this Section 11 shall be
   effected at the Registrant's expense, except for underwriting discounts
   and commissions and the fees and the expenses of counsel to the Designated
   Holder, and the Registrant shall provide to the underwriters such
   documentation (including certificates, opinions of counsel and "comfort"
   letters from auditors) as is customary in connection with underwritten
   public offerings as such underwriters may reasonably require.

             (i)  In connection with any registration effected under this
   Section 11, the parties agree

                  (i)  to indemnify each other and the underwriters in the
   customary manner,

                  (ii) to enter into an underwriting agreement in form and
   substance customary for transactions of such type with the Manager and the
   other underwriters participating in such offering, and

                  (iii)     to take all further actions which shall be
   reasonably necessary to effect such registration and sale (including if
   the Manager deems it necessary, participating in road show presentations).

             (j)  The Registrant shall be entitled to include (at its
   expense) additional shares of its common stock in a registration effected
   pursuant to this Section 11 only if and to the extent the Manager
   determines that such inclusion will not adversely affect the prospects for
   success of such offering.

        12.  Without limitation to any restriction on Issuer contained in
   this Agreement or in the Merger Agreement, in the event of any change in
   Issuer Common Stock by reason of stock dividends, splitups, mergers (other
   than the Merger), recapitalizations, combinations, exchange of shares or
   the like, the type and number of shares or securities subject to the
   Option, and the Option Price provided in Section 1, shall be adjusted
   appropriately to restore to Grantee its rights hereunder, including the
   right to purchase from Issuer (or its successors) shares of Issuer Common
   Stock (or such other shares or securities into which Issuer Common Stock
   has been so changed) for the aggregate Option Price as provided in Section
   1.

        13.  Each certificate representing Option Shares issued to Grantee
   hereunder, and Grantee Shares, if any, delivered to Issuer at a Closing,
   shall include a legend in substantially the following form:

        THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
        REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY
        STATE SECURITIES OR BLUE SKY LAWS, AND MAY BE REOFFERED OR SOLD
        ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION
        IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL
        RESTRICTIONS ON TRANSFER AS SET FORTH IN A STOCK OPTION AND
        TRIGGER PAYMENT AGREEMENT, DATED AS OF NOVEMBER 13, 1996, A COPY
        OF WHICH MAY BE OBTAINED FROM THE ISSUER UPON REQUEST.

   It is understood and agreed that:

                  (i)  the reference to the resale restrictions of the
   Securities Act and state securities or Blue Sky laws in the above legend
   shall be removed by delivery of substitute certificate(s) without such
   reference if Grantee or Issuer, as the case may be, shall have delivered
   to the other party a copy of a letter from the staff of the Securities and
   Exchange Commission, or an opinion of counsel, in form and substance
   reasonably satisfactory to the other party, to the effect that such legend
   is not required for purposes of the Securities Act or such laws;

                  (ii) the reference to the provisions to 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; 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.  Certificates representing shares sold in a registered
   public offering pursuant to Section 11 shall not be required to bear the
   legend set forth in this Section 13.

        14.  (a)  This Agreement shall be binding upon and inure to the
   benefit of the parties hereto and their respective successors and
   permitted assigns.

             (b)  Except as expressly provided for in this Agreement, neither
   this Agreement nor the rights or obligations of either party hereto are
   assignable, except by operation of law, or with the written consent of the
   other party.

             (c)  Nothing contained in this Agreement, express or implied, is
   intended to confer upon any person other than the parties hereto and their
   respective successors and permitted assigns any rights or remedies of any
   nature whatsoever by reason of this Agreement.

             (d)  Any Restricted Shares sold by a party in compliance with
   the provisions of Section 11 shall, upon consummation of such sale, be
   free of the restrictions imposed with respect to such shares by this
   Agreement, unless and until such party shall repurchase or otherwise
   become the beneficial owner of such shares, and any transferee of such
   shares shall not be entitled to the registration rights of such party.

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

             16.  If any term, provision, covenant or restriction contained
   in this Agreement is held by a court or a federal or state regulatory
   agency of competent jurisdiction to be invalid, void or unenforceable, the
   remainder of the terms, provisions and covenants and restrictions
   contained in this Agreement shall remain in full force and effect, and
   shall in no way be affected, impaired or invalidated.  Subject to Section
   5, if for any reason any such court or regulatory agency determines that
   Grantee is not permitted to acquire, or Issuer is not permitted to
   repurchase pursuant to Section 8, the full number of Option Shares
   provided in Section 1 hereof (as the same may be adjusted), it is the
   express intention of Issuer to allow Grantee to acquire or to require
   Issuer to repurchase such lesser number of shares as may be permissible
   without any amendment or modification hereof.

             17.  All notices and other communications hereunder shall be in
   writing and shall be deemed given if delivered personally, telecopied
   (with confirmation), mailed by registered or certified mail (return
   receipt requested) or delivered by an express courier (with confirmation) 
   at the respective addresses of the parties set forth in the Merger
   Agreement (or at such other address for a party as shall be specified by
   like notice).

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

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

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

             21.  Except as otherwise expressly provided herein or in the
   Merger Agreement, this Agreement contains the entire agreement between the
   parties with respect to the transactions contemplated hereunder and
   supersedes all prior arrangements or understandings with respect thereof,
   written or oral.

             22.  This Agreement may be amended by the parties hereto and the
   terms and conditions hereof may be waived only by an instrument in writing
   signed on behalf of each of the parties hereto, or, in the case of a
   waiver, by an instrument signed on behalf of the party waiving compliance.

             23.  The time periods for exercises of certain rights under
   Sections 2, 5 and 8 shall be extended (but in no event by more than six
   months):

             (a)  to the extent necessary to obtain all regulatory approvals
   for the exercise of such rights; and 

             (b)  to the extent necessary to avoid any liability under
   Section 16(b) of the Exchange Act by reason of such exercise.

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

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

                                           Officer




   

                                                                    Exhibit B
                                                               Execution Copy

             STOCK OPTION AND TRIGGER PAYMENT AGREEMENT (the "Agreement"),
   dated November 13, 1996, between OSB Financial Corp., a Wisconsin
   corporation ("Issuer"), and FCB Financial Corp., a Wisconsin corporation
   ("Grantee").


                              W I T N E S S E T H:


             WHEREAS, Grantee and Issuer have entered into an Agreement and
   Plan of Merger of even date herewith (the "Merger Agreement"), which
   agreement has been executed by the parties hereto immediately prior to
   this Stock Option and Trigger Agreement; and

             WHEREAS, as a condition to Grantee's entering into the Merger
   Agreement and in consideration therefor, Issuer has agreed to grant
   Grantee the Option (as hereinafter defined).

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

        1.   (a)  Issuer hereby grants to Grantee an unconditional,
   irrevocable option (the "Option") to purchase, subject to the terms
   hereof, up to 230,866 fully paid and nonassessable (except as otherwise
   provided by Section 180.0622(2)(b) of the Wisconsin Business Corporation
   Law) shares (the "Option Shares") of Issuer's Common Stock, par value
   $0.01 per share ("Issuer Common Stock"), at a price of $24.375 per share
   (the "Option Price"); provided, however, that in no event shall the number
   of shares of Issuer Common Stock for which this Option is exercisable
   exceed 19.9% of the issued and outstanding shares of Issuer Common Stock
   without giving effect to any shares subject to or issued pursuant to the
   Option.  The number of shares of Issuer 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 Issuer Common
   Stock are either (i) issued or otherwise become outstanding after the date
   of this Agreement (other than pursuant to this Agreement) or (ii)
   redeemed, repurchased, retired or otherwise cease to be outstanding after
   the date of this Agreement (such event a "Change in Shares Outstanding
   Event"), the number of shares of Issuer Common Stock subject to the Option
   shall be increased or decreased, as appropriate, so that, after such
   Change in Shares Outstanding Event, such number equals 19.9% of the number
   of shares of Issuer Common Stock then issued and outstanding without
   giving effect to any shares subject or issued pursuant to the Option. 
   Nothing contained in this Section 1(b) or elsewhere in this Agreement
   shall be deemed to authorize Issuer to issue or redeem, repurchase, or
   retire shares of Issuer Common Stock or to authorize either the Issuer or
   the Grantee otherwise to breach any provision of the Merger Agreement.

             (c)  The Option Price shall be payable, at the option of the
   Grantee, as follows:

                  (i)  in cash, or

                  (ii) subject to the receipt of all approvals of any
   Governmental Entity required for the Issuer to acquire, and Grantee to
   issue, the Grantee Shares (as defined below) from Grantee, in shares of
   common stock, $0.01 par value, of Grantee ("Grantee Shares"),

   in either case in accordance with Section 4 hereof.

             (d)  As used in this Agreement, the "Fair Market Value" of any
   share shall be the average of the last sales price for such share on The
   Nasdaq Stock Market during the ten trading days prior to the fifth trading
   day preceding the date such Fair Market Value is to be determined.

        2.   (a)  The Option may be exercised by Grantee, in whole or in
   part, at any time or from time to time after the Merger Agreement becomes
   terminable by Grantee under circumstances which could entitle Grantee to a
   termination fee (as opposed to the reimbursement of expenses only) under
   Section 8.3(a) of the Merger Agreement or Section 8.3(b) of the Merger
   Agreement (regardless of whether the Merger Agreement is actually
   terminated), any such event by which the Merger Agreement becomes so
   terminable by Grantee being referred to herein as a " Trigger Event."

             (b)  (i)  Issuer shall notify Grantee promptly in writing of the
   occurrence of any Trigger Event, it being understood that the giving of
   such notice by Issuer shall not be a condition to the right of Grantee to
   exercise the Option.

                  (ii) In the event Grantee wishes to exercise the Option,
   Grantee shall deliver to Issuer written notice (an "Exercise Notice")
   specifying the total number of Option Shares it wishes to purchase.

                  (iii)     Upon the giving by Grantee of Issuer of the
   Exercise Notice and the tender of the applicable aggregate Option Price,
   Grantee, to the extent permitted by law and Issuer's organizational
   documents, and provided that the conditions to Issuer's obligation to
   issue Option Shares to Grantee hereunder set forth in Section 3 have been
   satisfied or waived, shall be deemed to be the holder of record of the
   Option Shares issuable upon such exercise, notwithstanding that the stock
   transfer books of Issuer shall then be closed or that certificates
   representing such Option Shares shall not then be actually delivered to
   Grantee.

                  (iv) Each closing of a purchase of Option Shares (a
   "Closing") shall occur at a place, on a date, and at a time designated by
   Grantee in an Exercise Notice delivered at least two business days prior
   to the date of the Closing.

             (c)  The Option shall terminate upon the earliest to occur of:

                  (i)  the Effective Time of the Merger;

                  (ii) the termination of the Merger Agreement pursuant to
   Section 8.1 thereof, other than under circumstances which also constitute
   a Trigger Event under this Agreement;

                  (iii)     180 days following any termination of the Merger
   Agreement upon or during the continuance of a Trigger Event (or if, at the
   expiration of such 180-day period, the Option cannot be exercised by
   reason of any applicable judgment, decree, order, law or regulation, ten
   business days after such impediment to exercise shall have been removed or
   shall have become final and not subject to appeal, but in no event under
   this clause (iii) later than September 30, 1997); and

                  (iv) payment by Issuer of the Trigger Payment set forth in
   Section 5 of this Agreement to Grantee.

             (d)  Notwithstanding the foregoing, the Option may not be
   exercised if (i) Grantee is in material breach of any of its
   representations or warranties, or in material breach of any of its
   covenants or agreements, contained in this Agreement or in the Merger
   Agreement, or (ii) a Trigger Payment has been paid pursuant to Section 5
   of this Agreement or demand therefor has been made and not withdrawn.

        3.   The obligation of Issuer to issue Option Shares to Grantee
   hereunder is subject to the conditions that

             (a)  the Option Shares, and any Grantee Shares which are issued
   in payment of the Option Price, shall have been approved for listing on
   The Nasdaq Stock Market;

             (b)  all consents, approvals, orders or authorizations of, or
   registrations, declarations or filings with, any federal, state or local
   administrative agency or commission or other federal, state or local
   Governmental Entity, if any, required in connection with the issuance by
   Issuer and the acquisition by Grantee of the Option Shares hereunder shall
   have been obtained or made; and

             (c)  no preliminary or permanent injunction or other order by
   any court of competent jurisdiction prohibiting or otherwise restraining
   such issuance shall be in effect.

   The condition set forth in paragraph (a) above may be waived by Issuer, in
   the case of Grantee Shares, and by Grantee, in the case of Option Shares,
   in the sole discretion of the waiving party.

        4.   At any Closing,

             (a)  Issuer shall deliver to Grantee or its designee a single
   certificate in definitive form representing the number of Option Shares
   designated by Grantee in its Exercise Notice, such certificate to be
   registered in the name of Grantee and to bear the legend set forth in
   Section 13; and 

             (b)  Grantee shall deliver to issuer the aggregate price for the
   Option Shares so designated and being purchased by

                  (i)  wire transfer of immediately available funds or
   certified check or bank check, or

                  (ii) subject to the condition in Section 1(c)(ii), delivery
   of a certificate or certificates representing the number of Grantee Shares
   being issued by Grantee in consideration thereof, determined in accordance
   with Section 4(c).

             (c)  In the event that Grantee issues Grantee Shares to Issuer
   in consideration of Option Shares pursuant to Section 4(b)(ii), the number
   of Grantee Shares to be so issued shall be equal to the quotient obtained
   by dividing:

                  (i)  the product of (x) the number of Option Shares with
   respect to which the Option is being exercised and (y) the Option Price,
   by

                  (ii) the Fair Market Value of the Grantee Shares as of the
   date immediately preceding the date the Exercise Notice is delivered to
   Issuer.

             (d)  Issuer shall pay all expenses, and any and all 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 4.

        5.   (a)  Subject to the provisions of Section 8.3(d) of the Merger
   Agreement, if a Trigger Event shall have occurred and any regulatory
   approval or order required for the issuance by Issuer, or the acquisition
   by Grantee, of the Option or the Option Shares upon exercise of the Option
   shall not have been obtained, Grantee shall have the right to receive, and
   Issuer shall pay to Grantee, an amount (the "Trigger Payment") equal to
   the product of

                  (i)  the maximum number of Option Shares that would have
   been subject to purchases by Grantee upon exercise of the Option pursuant
   to Sections 1 and 2 hereof if all such regulatory approvals or orders had
   been obtained, and

                  (ii) the difference between (A) the Market/Offer Price (as
   defined herein), determined as of the date on which notice of demand for
   the Trigger Payment is given by Grantee, and (B) the Option Price (but
   only if such Market/Offer Price is higher than such Option Price).

   Demand for the Trigger Payment shall be given by notice in accordance with
   the provisions of Section 17 hereof.  The Trigger Payment shall be paid to
   Grantee by Issuer on the Payment Date (as defined herein), by wire
   transfer or immediately available funds to an account to be designated in
   writing by Grantee not less than two business days before the Payment
   Date.

             (b)  For purposes of this Section 5, "Payment Date" means the
   date on which termination fees are required to be paid by Issuer to
   Grantee under Sections 8.3(a) or 8.3(b), as the case may be, of the Merger
   Agreement as a result of the occurrence of the Trigger Event referred to
   in subsection (a) of this Section 5 or such later date as Grantee shall
   specify with two business days prior written notice to Issuer.

             (c)  Issuer shall have no obligation to pay the Trigger Payment
   if Grantee is in material breach of any of its representations or
   warranties, or in material breach of any of its covenants or agreements,
   contained in this Agreement or in the Merger Agreement.

        6.   Issuer represents and warrants to Grantee that

             (a)  Issuer has the corporate power and authority to enter into
   this Agreement and to carry out its obligations hereunder, subject in the
   case of the repurchase of the Option Shares pursuant to Section 8(a) to
   applicable law;

             (b)  this Agreement has been duly and validly executed and
   delivered by Issuer, and, assuming the due authorization, execution and
   delivery hereof by Grantee and the receipt of all required regulatory
   approvals, constitutes a valid and binding obligation of Issuer,
   enforceable against Issuer in accordance with its terms;

             (c)  Issuer has taken all necessary corporate action to
   authorize and reserve for issuance and to permit it to issue, upon
   exercise of the Option, and at all times from the date hereof through the
   expiration of the Option will have reserved, the number of authorized and
   unissued Option Shares, such amount being subject to adjustment as
   provided in Sections 1 and 12, all of which, upon their issuance and
   delivery in accordance with the terms of this Agreement, will be duly
   authorized, validly issued, fully paid and nonassessable (except as
   otherwise provided by Section 180.0622(2)(b) of the Wisconsin Business
   Corporation Law);

             (d)  upon delivery of the Option Shares to Grantee upon the
   exercise of the Option, Grantee will acquire the Option Shares free and
   clear of all claims, liens, charges, encumbrances and security interests
   of any nature whatsoever;

             (e)  except as described in Section 3.4 of the Merger Agreement,
   the execution and delivery of this Agreement by Issuer does not, and,
   subject to compliance with applicable law with respect to the repurchase
   of the Option Shares pursuant to Section 8(a), the consummation by Issuer
   of the transactions contemplated hereby will not, violate, conflict with,
   or result in a breach of any provision of, or constitute a default (with
   or without notice or a lapse of time, or both) under, or result in the
   termination of, or accelerate the performance required by, or result in a
   right of termination, cancellation, or acceleration of any obligation or
   the loss of a material benefit under, or the creation of a lien, pledge,
   security interest or other encumbrance on assets (any such conflict,
   violation, default, right of termination, cancellation, acceleration, loss
   or creation, hereinafter a "Violation") of Issuer or any of its
   Subsidiaries, pursuant to

                  (i)  any provision of the Articles of Incorporation or the
   Bylaws of Issuer,

                  (ii) any provisions of any material loan or credit
   agreement, note, mortgage, indenture, lease, benefit plan or other
   agreement, obligation, instrument, permit, concession, franchise or
   license (any of the foregoing in effect on the date hereof being referred
   to as a "Material Contract") of Issuer or its Subsidiaries or to which any
   of them is a party, or

                  (iii)     any judgment, order, decree, statute, law,
   ordinance, rule or regulation applicable to Issuer or its properties or
   assets,

   which Violation, in the case of each clauses (ii) and (iii), could
   reasonably be expected to have a Material Adverse Effect on Issuer (except
   that no representation or warranty is given concerning any Violation of a
   Material Contract with respect to the repurchase of Option Shares pursuant
   to Section 8(a));

             (f)  except as described in Section 3.4 of the Merger Agreement,
   the execution and delivery of this Agreement by Issuer does not, and the
   performance of this Agreement by Issuer will not, require any consent,
   approval, authorization or permit of, filing with or notification to, any
   Governmental Entity;

             (g)  none of Issuer, any of its affiliates or anyone acting on
   its or their behalf, has issued, sold or offered any security of Issuer to
   any person under circumstances that would cause the issuance and sale of
   the Option Shares, as contemplated by this Agreement, to be subject to the
   registration requirements of the Securities Act of 1933, as amended (the
   "Securities Act"), as in effect on the date hereof, and, assuming the
   representations and warranties of Grantee contained in Section 7(g) are
   true and correct, the issuance, sale and delivery of the Option Shares
   hereunder would be exempt from the registration and prospectus delivery
   requirements of the Securities Act, as in effect on the date hereof (and
   Issuer shall not take any action which would cause the issuance, sale, and
   delivery of the Option Shares hereunder not to be exempt from such
   requirements); and

             (h)  any Grantee Shares acquired pursuant to this Agreement will
   be acquired for Issuer's own account, for investment purposes only, and
   will not be acquired by Issuer with a view to the public distribution
   thereof in violation of any applicable provision of the Securities Act.

        7.   Grantee represents and warrants to Issuer that

             (a)  Grantee has the corporate power and authority to enter into
   this Agreement and to carry out its obligations hereunder;

             (b)  this Agreement has been duly and validly executed and
   delivered by Grantee and, assuming the due authorization, execution and
   delivery hereof by Issuer and the receipt of all required regulatory
   approvals, constitutes a valid and binding obligation of Grantee,
   enforceable against Grantee in accordance with its respective terms;

             (c)  prior to any delivery of Grantee Shares in consideration of
   the purchase of Option Shares pursuant hereto, Grantee will have taken all
   necessary corporate action to authorize for issuance and to permit it to
   issue such Grantee Shares, all of which, upon their issuance and delivery
   in accordance with the terms of this Agreement, will be duly authorized,
   validly issued, fully paid and nonassessable (except as otherwise provided
   in Section 180.0622(2)(b) of the Wisconsin Business Corporation Law);

             (d)  upon any delivery of such Grantee Shares to Issuer in
   consideration of the purchase of the Option Shares pursuant hereto, Issuer
   will acquire the Grantee Shares free and clear of all claims, liens,
   charges, encumbrances and security interests of any nature whatsoever;

             (e)  except as described in Section 3.4 of the Merger Agreement,
   the execution and delivery of this Agreement by Grantee does not, and the
   consummation by Grantee of the transactions contemplated hereby will not,
   violate, conflict with, or result in the breach of any provision of, or
   constitute a default (with or without notice or a lapse of time, or both)
   under, or result in any Violation by Grantee or any of its Subsidiaries,
   pursuant to

                  (i)  any provision of the Articles of Incorporation or
   Bylaws of Grantee,

                  (ii) any Material Contract of Grantee or any of its
   Subsidiaries or to which any of them is a party, or

                  (iii)     any judgment, order, decree, statute, law,
   ordinance, rule or regulation applicable to Grantee or its properties or
   assets,

   which Violation, in the case of each of clauses (ii) or (iii), would have
   a Material Adverse Effect on Grantee;

             (f)  except as described in Section 3.4 of the Merger Agreement,
   the execution and delivery of this Agreement by Grantee does not, and the
   consummation by Grantee of the transactions contemplated hereby will not,
   require any consent, approval, authorization or permit of, filing with or
   notification to, any Governmental Entity; and

             (g)  any Option Shares acquired upon exercise of the Option will
   be acquired for Grantee's own account, for investment purposes only and
   will not be, and the Option is not being, acquired by Grantee with a view
   to the public distribution thereof, in violation of any applicable
   provision of the Securities Act.

        8.   (a)  At the request of Grantee by written notice (x) at any time
   during which the Option is exercisable pursuant to Section 2 (the
   "Repurchase Period"), Issuer (or any successor entity thereof) shall, if
   permitted by applicable law, the Articles of Incorporation and Bylaws of
   the Issuer and Issuer's Material Contracts, repurchase from Grantee all or
   any portion of the Option, at the price set forth in subparagraph (i)
   below, or, (y) at any time prior to September 30, 1997, Issuer (or any
   successor entity thereof) shall, if permitted by applicable law, the
   Articles of Incorporation and Bylaws of Issuer and Issuer's Material
   Contracts, repurchase from Grantee all or any portion of the Option Shares
   purchased by Grantee pursuant to the Option, at the price set forth in
   subparagraph (ii) below:

                  (i)  (A)  The difference between the "Market/Offer Price"
   (as defined below) for shares of Issuer Common Stock as of the date
   Grantee gives notice of its intent to exercise its rights under this
   Section 8 and the Option Price, multiplied by the number of Option Shares
   purchasable pursuant to the Option (or portion thereof with respect to
   which Grantee is exercising its rights under this Section 8), but only if
   the Market/Offer Price is greater than the Option Price.

                       (B)  For purposes of this Agreement, "Market/Offer
   Price" shall mean, as of any date, the higher of (I) the price per share
   offered as of such date pursuant to any tender or exchange offer or other
   offer with respect to a Business Combination involving Issuer as the
   Target Party which was made prior to such date and not terminated or
   withdrawn as of such date and (II) the Fair Market Value per share of
   Issuer Common Stock as of such date.

                  (ii) (A)  The product of (I) the sum of (a) the Option
   Price paid by Grantee per Option Share acquired pursuant to the Option,
   and (b) the difference between the "Offer Price" (as defined below) and
   the Option Price, but only if the Offer Price is greater than the Option
   Price, and (II) the number of Option Shares so to be repurchased pursuant
   to this Section 8.

                       (B)  For purposes of this clause (ii), the "Offer
   Price" shall be the highest price per share offered pursuant to a tender
   or exchange offer or other Business Combination offer involving Issuer as
   the Target Party during the Repurchase Period prior to the delivery by
   Grantee of a notice of repurchase.

             (b)  If Grantee shall have previously elected to purchase Option
   Shares pursuant to the exercise of the Option by the issuance and delivery
   of Grantee Shares, then Issuer shall, if so requested by Grantee, in
   fulfillment of its obligation pursuant to Section 8(a)(y) (that is, with
   respect to the Option Price only and without limitation to its obligation
   to pay additional consideration under clause (b) of Section
   8(a)(ii)(A)(I)), redeliver the certificates for such Grantee Shares to
   Grantee, free and clear of all liens, claims, charges and encumbrances of
   any kind or nature whatsoever; provided, however, that if at any time less
   than all of the Option Shares so purchased by Grantee pursuant to the
   Option are to be repurchased by Issuer pursuant to Section 8(a)(y), then
   (i) Issuer shall be obligated to redeliver to Grantee the same proportion
   of such Grantee Shares as the number of Option Shares that Issuer is then
   obligated to repurchase bears to the number of Option Shares acquired by
   Grantee upon exercise of the Option and (ii) Grantee shall issue to Issuer
   new certificates representing those Grantee Shares which are not due to be
   redelivered to Grantee pursuant to this Section 8(b) to the extent that
   excess Grantee Shares are included in the certificates redelivered to
   Grantee by Issuer.

             (c)  In the event Grantee exercises its rights under this
   Section 8, Issuer shall, within ten business days thereafter, pay the
   required amount to Grantee in immediately available funds and Grantee
   shall surrender to Issuer the Option or the certificate or certificates
   evidencing the Option Shares purchased by Grantee pursuant hereto, and
   Grantee shall warrant that it owns the Option or such shares and that the
   Option or such shares are then free and clear of all liens, claims,
   damages, charges and encumbrances of any kind or nature whatsoever.

             (d)  If Grantee has elected to purchase Option shares pursuant
   to the exercise of the Option by the issuance and delivery of Grantee
   Shares, notwithstanding that Grantee may no longer hold any such Option
   Shares or that Grantee elects not to exercise its other rights under this
   Section 8, Grantee may require, at any time or from time to time prior to
   September 30, 1997, Issuer to sell to Grantee any such Grantee Shares at
   the price attributed to such Grantee Shares pursuant to Section 4 plus
   interest at the publicly announced prime rate as published in the Wall
   Street Journal (Midwest Edition) on such amount from the Closing Date
   relating to the exchange of such Grantee shares pursuant to Section 4 to
   the Closing Date under this Section 8(d) less any dividends on such
   Grantee Shares paid during such period or declared and payable to
   shareholders of record on a date during such period.

             (e)  In the event the repurchase price specified in Section 8(a)
   would subject the purchase of the Option or the Option Shares purchased by
   Grantee pursuant to the Option to a vote of the shareholders of Issuer
   pursuant to applicable law or the Articles of Incorporation of Issuer,
   then Grantee may, at its election, reduce the repurchase price to an
   amount which would permit such repurchase without the necessity for such a
   shareholder vote.

        9.   Following the date hereof and prior to the fifth anniversary of
   the date hereof (the "Expiration Date"), each party shall vote any shares
   of capital stock of the other party acquired by such party pursuant to
   this Agreement ("Restricted Shares"), including any Grantee Shares issued
   pursuant to Section 1(c), or otherwise beneficially owned (within the
   meaning of Rule 13d-3 promulgated under the Securities Exchange Act of
   1934, as amended (the "Exchange Act")), by such party on each matter
   submitted to a vote of shareholders of such other party for and against
   such matter in the same proportion as the vote of all other shareholders
   of such other party are voted (whether by proxy or otherwise) for and
   against such matter.

        10.  (a)  Prior to the Expiration Date, neither party shall, directly
   or indirectly, sell, assign, pledge, or otherwise dispose of or transfer
   any Restricted Shares beneficially owned by such party, other than (i)
   pursuant to Section 8, or (ii) in accordance with Section 10(b) or
   Section 11.

             (b)  Following the termination of the Merger Agreement, a party
   shall be permitted to sell any Restricted Shares beneficially owned by it
   if such sale is made pursuant to a tender or exchange offer that has been
   approved or recommended, or otherwise determined to be fair to and in the
   best interests of the shareholders of the other party, by a majority of
   the members of the Board of Directors of such other party, which majority
   shall include a majority of directors who were directors prior to the
   announcement of such tender or exchange offer.

        11.  (a)  Following the termination of the Merger Agreement, either
   party hereto that owns Restricted Shares (a "Designated Holder") may by
   written notice (the "Registration Notice") to the other party (the
   "Registrant") request the Registrant to register under the Securities Act
   all or any part of the Restricted Shares beneficially owned by such
   Designated Holder (the "Registrable Securities") pursuant to a bona fide
   firm commitment underwritten public offering, in which the Designated
   Holder and the underwriters shall effect as wide a distribution of such
   Registrable Securities as is reasonably practicable and shall use their
   best efforts to prevent any person (including any Group (as used in Rule
   13d-5 under the Exchange Act)) and its affiliates from purchasing through
   such offering Restricted Shares representing more than 1% of the
   outstanding shares of common stock of the Registrant on a fully diluted
   basis (a "Permitted Offering").

             (b)  The Registration Notice shall include a certificate
   executed by the Designated Holder and its proposed managing underwriter,
   which underwriter shall be an investment banking firm of recognized
   standing on a national or regional basis (the "Manager"), stating that

                  (i)  they have a good faith intention to commence promptly
   a Permitted Offering, and

                  (ii) Manager in good faith believes that, based on the
   then-prevailing market conditions, it will be able to sell the Registrable
   Securities at a per share price equal to at least 80% of the then Fair
   Market Value of such shares.

             (c)  The Registrant (and/or any person designed by the
   Registrant) shall thereupon have the option exercisable by written notice
   delivered to the Designated Holder within ten business days after the
   receipt of the Registration Notice, irrevocably to agree to purchase all
   or any part of the Registrable Securities proposed to be so sold for cash
   at a price equal to the product of (i) the number of Registrable
   Securities to be so purchased by the Registrant and (ii) the then Fair
   Market Value of such shares.

             (d)  Any purchase of Registrable Securities by the Registrant
   (or its designee) under Section 11(c) shall take place at a closing to be
   held at the principal executive offices of the Registrant or at the
   offices of its counsel at any reasonable date and time designated by the
   Registrant and/or such designee in such notice within twenty business days
   after delivery of such notice, and any payment for the shares to be so
   purchased shall be made by delivery at the time of such closing in
   immediately available funds.

             (e)  If the Registrant does not elect to exercise its option
   pursuant to this Section 11 with respect to all Registrable Securities, it
   shall use its best efforts to effect, as promptly as practicable, the
   registration under the Securities Act of the unpurchased Registrable
   Securities proposed to be so sold; provided, however, that

                  (i)  neither party shall be entitled to demand more than an
   aggregate of two effective registration statements hereunder, and

                  (ii) the Registrant will not be required to file any such
   registration statement during any period of time (not to exceed 40 days
   after such request in the case of clause (A) below or 90 days in the case
   of clauses (B) and (C) below) when

                       (A)  the Registrant is in possession of material non-
   public information which it reasonably believes would be detrimental to be
   disclosed at such time and, in the opinion of counsel to the Registrant,
   such information would be required to be disclosed if a registration
   statement were filed at that time;

                       (B)  the Registrant is required under the Securities
   Act to include audited financial statements for any period in such
   registration statement and such financial statements are not yet available
   for inclusion in such registration statement; or 

                       (C)  the Registrant determines, in its reasonable
   judgment, that such registration would interfere with any financing,
   acquisition or other material transaction involving the Registrant or any
   of its affiliates.

             (f)  The Registrant shall use its reasonable best efforts to
   cause any Registrable Securities registered pursuant to this Section 11 to
   be qualified for sale under the securities or Blue Sky laws of such
   jurisdictions as the Designated Holder may reasonably request and shall
   continue such registration or qualification in effect in such
   jurisdiction; provided, however, that the Registrant shall not be required
   to qualify to do business in, or consent to general service of process in,
   any jurisdiction by reason of this provision.

             (g)  The registration rights set forth in this Section 11 are
   subject to the condition that the Designated Holder shall provide the
   Registrant with such information with respect to such holder's Registrable
   Securities, the plans for the distribution thereof, and such other
   information with respect to such holder as, in the reasonable judgment of
   counsel for the Registrant, is necessary to enable the Registrant to
   include in such registration statement all material facts required to be
   disclosed with respect to a registration thereunder.

             (h)  A registration effected under this Section 11 shall be
   effected at the Registrant's expense, except for underwriting discounts
   and commissions and the fees and the expenses of counsel to the Designated
   Holder, and the Registrant shall provide to the underwriters such
   documentation (including certificates, opinions of counsel and "comfort"
   letters from auditors) as is customary in connection with underwritten
   public offerings as such underwriters may reasonably require.

             (i)  In connection with any registration effected under this
   Section 11, the parties agree

                  (i)  to indemnify each other and the underwriters in the
   customary manner,

                  (ii) to enter into an underwriting agreement in form and
   substance customary for transactions of such type with the Manager and the
   other underwriters participating in such offering, and

                  (iii)     to take all further actions which shall be
   reasonably necessary to effect such registration and sale (including if
   the Manager deems it necessary, participating in road show presentations).

             (j)  The Registrant shall be entitled to include (at its
   expense) additional shares of its common stock in a registration effected
   pursuant to this Section 11 only if and to the extent the Manager
   determines that such inclusion will not adversely affect the prospects for
   success of such offering.

        12.  Without limitation to any restriction on Issuer contained in
   this Agreement or in the Merger Agreement, in the event of any change in
   Issuer Common Stock by reason of stock dividends, splitups, mergers (other
   than the Merger), recapitalizations, combinations, exchange of shares or
   the like, the type and number of shares or securities subject to the
   Option, and the Option Price provided in Section 1, shall be adjusted
   appropriately to restore to Grantee its rights hereunder, including the
   right to purchase from Issuer (or its successors) shares of Issuer Common
   Stock (or such other shares or securities into which Issuer Common Stock
   has been so changed) for the aggregate Option Price as provided in Section
   1.

        13.  Each certificate representing Option Shares issued to Grantee
   hereunder, and Grantee Shares, if any, delivered to Issuer at a Closing,
   shall include a legend in substantially the following form:

        THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
        REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY
        STATE SECURITIES OR BLUE SKY LAWS, AND MAY BE REOFFERED OR SOLD
        ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION
        IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL
        RESTRICTIONS ON TRANSFER AS SET FORTH IN A STOCK OPTION AND
        TRIGGER PAYMENT AGREEMENT, DATED AS OF NOVEMBER 13, 1996, A COPY
        OF WHICH MAY BE OBTAINED FROM THE ISSUER UPON REQUEST.

   It is understood and agreed that:

                  (i)  the reference to the resale restrictions of the
   Securities Act and state securities or Blue Sky laws in the above legend
   shall be removed by delivery of substitute certificate(s) without such
   reference if Grantee or Issuer, as the case may be, shall have delivered
   to the other party a copy of a letter from the staff of the Securities and
   Exchange Commission, or an opinion of counsel, in form and substance
   reasonably satisfactory to the other party, to the effect that such legend
   is not required for purposes of the Securities Act or such laws;

                  (ii) the reference to the provisions to 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; 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.  Certificates representing shares sold in a registered
   public offering pursuant to Section 11 shall not be required to bear the
   legend set forth in this Section 13.

        14.  (a)  This Agreement shall be binding upon and inure to the
   benefit of the parties hereto and their respective successors and
   permitted assigns.

             (b)  Except as expressly provided for in this Agreement, neither
   this Agreement nor the rights or obligations of either party hereto are
   assignable, except by operation of law, or with the written consent of the
   other party.

             (c)  Nothing contained in this Agreement, express or implied, is
   intended to confer upon any person other than the parties hereto and their
   respective successors and permitted assigns any rights or remedies of any
   nature whatsoever by reason of this Agreement.

             (d)  Any Restricted Shares sold by a party in compliance with
   the provisions of Section 11 shall, upon consummation of such sale, be
   free of the restrictions imposed with respect to such shares by this
   Agreement, unless and until such party shall repurchase or otherwise
   become the beneficial owner of such shares, and any transferee of such
   shares shall not be entitled to the registration rights of such party.

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

             16.  If any term, provision, covenant or restriction contained
   in this Agreement is held by a court or a federal or state regulatory
   agency of competent jurisdiction to be invalid, void or unenforceable, the
   remainder of the terms, provisions and covenants and restrictions
   contained in this Agreement shall remain in full force and effect, and
   shall in no way be affected, impaired or invalidated.  Subject to Section
   5, if for any reason any such court or regulatory agency determines that
   Grantee is not permitted to acquire, or Issuer is not permitted to
   repurchase pursuant to Section 8, the full number of Option Shares
   provided in Section 1 hereof (as the same may be adjusted), it is the
   express intention of Issuer to allow Grantee to acquire or to require
   Issuer to repurchase such lesser number of shares as may be permissible
   without any amendment or modification hereof.

             17.  All notices and other communications hereunder shall be in
   writing and shall be deemed given if delivered personally, telecopied
   (with confirmation), mailed by registered or certified mail (return
   receipt requested) or delivered by an express courier (with confirmation) 
   at the respective addresses of the parties set forth in the Merger
   Agreement (or at such other address for a party as shall be specified by
   like notice).

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

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

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

             21.  Except as otherwise expressly provided herein or in the
   Merger Agreement, this Agreement contains the entire agreement between the
   parties with respect to the transactions contemplated hereunder and
   supersedes all prior arrangements or understandings with respect thereof,
   written or oral.

             22.  This Agreement may be amended by the parties hereto and the
   terms and conditions hereof may be waived only by an instrument in writing
   signed on behalf of each of the parties hereto, or, in the case of a
   waiver, by an instrument signed on behalf of the party waiving compliance.

             23.  The time periods for exercises of certain rights under
   Sections 2, 5 and 8 shall be extended (but in no event by more than six
   months):

             (a)  to the extent necessary to obtain all regulatory approvals
   for the exercise of such rights; and 

             (b)  to the extent necessary to avoid any liability under
   Section 16(b) of the Exchange Act by reason of such exercise.

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

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

                                                               Execution Copy

                                 Plan of Merger
                                     Between
                               FCB Financial Corp.
                                       and
                               OSB Financial Corp.


             PLAN OF MERGER (this "Plan"), dated as of November 13, 1996, by
   and between FCB Financial Corp., a Wisconsin corporation ("FCB"), and
   OSB Financial Corp., a Wisconsin corporation ("OSB").

             WHEREAS, the Boards of Directors of FCB and OSB have determined
   that it is in the best interests of their respective corporations and
   their shareholders to consummate a merger in which OSB will merge with and
   into FCB (the "Merger"), so that FCB is the resulting corporation
   (hereinafter sometimes called the "Surviving Corporation") in the Merger;

             WHEREAS, FCB and OSB have entered into an Agreement and Plan of
   Merger, dated November 13, 1996 (the "Agreement"), which sets forth the
   terms of the Merger;

             WHEREAS, this Plan provides for the terms and conditions of the
   Merger and the mode for carrying the Merger into effect.

             NOW, THEREFORE, in consideration of the mutual covenants and
   agreements contained herein, and other good and valuable consideration,
   the receipt and sufficiency of which are hereby acknowledged, the parties
   agree as follows:

                                    ARTICLE I
                                   THE MERGER

             1.1  The Merger.  Subject to the terms and conditions of the
   Agreement and this Plan, and in accordance with the Wisconsin Business
   Corporation Law (the "WBCL"), at the Effective Time (as defined in Section
   1.2), OSB shall merge with and into FCB, and FCB shall survive the Merger
   and shall continue its corporate existence under the laws of the State of
   Wisconsin.  Upon consummation of the Merger, the separate corporate
   existence of OSB shall terminate and the name of the Surviving Corporation
   shall be "FCB Financial Corp."

             1.2  Effective Time.  The Merger shall become effective upon the
   later of (a) the time of filing of Articles of Merger with the Department
   of Financial Institutions of the State of Wisconsin (the "Wisconsin
   Department") and (b) the effective date and time of the Merger as set
   forth in such Articles of Merger.  The parties shall each use reasonable
   efforts to cause Articles of Merger to be filed on the Closing Date (as
   defined in Section 1.19).  The term "Effective Time" shall be the date and
   time when the Merger becomes effective, in accordance with this
   Section 1.2.

             1.3  Effects of the Merger.  At and after the Effective Time,
   the Merger shall have the effects set forth in Section 180.1106 of the
   WBCL.

             1.4  Conversion of OSB Common Stock; Treatment of FCB Common
   Stock.
   *
                  (a)  At the Effective Time, subject to Section 2.2, by
        virtue of the Merger and without any action on the part of OSB, or
        the holder of any securities of OSB, each share of the common stock,
        $.01 par value, of OSB (the "OSB Common Stock") issued and
        outstanding immediately prior to the Effective Time (other than
        shares canceled pursuant to Section 1.4(c)) shall be converted into
        the right to receive 1.46 shares (the "OSB Exchange Ratio") of the
        common stock, par value $.01 per share, of FCB (the "FCB Common
        Stock").

                  (b)  All of the shares of OSB Common Stock converted into
        FCB Common Stock pursuant to this Article I shall no longer be
        outstanding and shall automatically be canceled and shall cease to
        exist as of the Effective Time, and each certificate (each an "OSB
        Common Stock Certificate") previously representing any such shares of
        OSB Common Stock shall thereafter represent only the right to receive
        (i) a certificate representing the number of whole shares of FCB
        Common Stock (each an "FCB Common Stock Certificate") and (ii) cash
        in lieu of fractional shares into which the shares of OSB Common
        Stock previously represented by such OSB Common Stock Certificate
        have been converted pursuant to this Section 1.4 and Section 2.2. 
        OSB Common Stock Certificates previously representing shares of OSB
        Common Stock shall be exchanged for FCB Common Stock Certificates
        representing whole shares of FCB Common Stock and cash in lieu of
        fractional shares issued in consideration therefor upon the surrender
        of such OSB Common Stock Certificates in accordance with Section 2.2,
        without any interest thereon. 

                  (c)  At the Effective Time, all shares of OSB Common Stock
        that are owned by OSB as treasury stock, owned by the Oshkosh Savings
        Bank, FSB Management Development and Recognition Plan and not
        allocated to participants thereunder or owned by FCB, if any, shall
        be canceled and shall cease to exist, and no stock of FCB or other
        consideration shall be delivered in exchange therefor.

                  (d)  At and after the Effective Time, each share of FCB
        Common Stock issued and outstanding immediately prior to the
        Effective Time shall remain an issued and outstanding share of common
        stock of the Surviving Corporation and shall not be affected by the
        Merger.

             1.5  Articles of Incorporation.  The Articles of Incorporation
   of FCB in effect as of the Effective Time shall be the Articles of
   Incorporation of the Surviving Corporation after the Merger until
   thereafter amended in accordance with applicable law.

             1.6  By-Laws.  The By-Laws of FCB in effect as of the Effective
   Time shall be the By-Laws of the Surviving Corporation after the Merger
   until thereafter amended in accordance with applicable law.

             1.7  Tax Consequences.  It is intended that the Merger shall
   constitute a reorganization within the meaning of Section 368(a)(1)(A) of
   the Internal Revenue Code of 1986, as amended (the "Code"), and that the
   Agreement and this Plan shall constitute a "plan of reorganization" for
   the purposes of Section 368 of the Code.

             1.8  Board of Directors of the Surviving Corporation  From and
   after the Effective Time, the Board of Directors of the Surviving
   Corporation shall consist of fourteen (14) persons, including Donald D.
   Parker and James J. Rothenbach.  Six (6) directors, in addition to Donald
   D. Parker, shall have been selected by FCB ("FCB Representatives"), and
   six (6) directors, in addition to James J. Rothenbach, shall have been
   selected by OSB (the "OSB Representatives").  The FCB Representatives and
   the OSB Representatives, respectively, shall be divided as equally as
   practicable among the three classes of directors of the Surviving
   Corporation and shall serve in such capacities until their successors
   shall have been elected or appointed and shall have qualified in
   accordance with the Articles of Incorporation and By-laws of the Surviving
   Corporation and the WBCL.  Directors chosen from among the FCB
   Representatives and the OSB Representatives shall be equally represented
   on the personnel committee (which shall have four members) and the
   executive committee, if any, of the Board of Directors of the Surviving
   Corporation.

             1.9  Closing.  Subject to the terms and conditions of the
   Agreement and this Plan, the closing of the Merger (the "Closing") will
   take place at 10:00 a.m. on a date and at a place to be specified by the
   parties, which shall be no later than the first business day in the
   calendar month immediately following the month in which the last of the
   conditions precedent to the Merger set forth in Article VII of the
   Agreement is satisfied or waived, or at such other time, date and place as
   OSB and FCB shall mutually agree (the "Closing Date").

                                   ARTICLE II
                              CONVERSION OF SHARES

             2.1  FCB to Make Shares Available.  At or prior to the Effective
   Time, FCB shall deposit, or shall cause to be deposited, with a bank,
   trust company or other entity reasonably acceptable to OSB (the "Exchange
   Agent"), for the benefit of the holders of OSB Common Stock Certificates,
   for exchange in accordance with this Article II, FCB Common Stock
   Certificates and cash in lieu of any fractional shares of FCB Common Stock
   (such cash and FCB Common Stock Certificates, together with any dividends
   or distributions with respect thereto paid after the Effective Time, being
   hereinafter referred to as the "Conversion Fund") to be issued pursuant to
   Section 1.4 and paid pursuant to Section 2.2(a) in exchange for
   outstanding shares of OSB Common Stock.

             2.2  Exchange of Certificates.

                  (a)  As soon as practicable after the Effective Time, and
        in no event later than ten (10) business days thereafter, the
        Surviving Corporation shall cause the Exchange Agent to mail to each
        holder of record of one or more OSB Common Stock Certificates a
        letter of transmittal (which shall specify that delivery shall be
        effected, and risk of loss and title to the OSB Common Stock
        Certificates shall pass, only upon delivery of the OSB Common Stock
        Certificates to the Exchange Agent) and instructions for use in
        effecting the surrender of the OSB Common Stock Certificates in
        exchange for FCB Common Stock Certificates and any cash in lieu of
        fractional shares into which the shares of OSB Common Stock
        represented by such OSB Common Stock Certificate or Certificates
        shall have been converted pursuant to the Agreement and this Plan. 
        Upon proper surrender of an OSB Common Stock Certificate for exchange
        and cancellation to the Exchange Agent, together with such properly
        completed letter of transmittal, duly executed, the holder of such
        OSB Common Stock Certificate shall be entitled to receive in exchange
        therefor, as applicable, (i) an FCB Common Stock Certificate
        representing that number of whole shares of FCB Common Stock to which
        such holder of OSB Common Stock shall have become entitled pursuant
        to the provisions of Section 1.4 hereof, and (ii) a check
        representing the amount of any cash in lieu of fractional shares that
        such holder has the right to receive in respect of such OSB Common
        Stock Certificate, and the OSB Common Stock Certificate so
        surrendered shall forthwith be canceled.  No interest will be paid or
        accrued on any cash in lieu of fractional shares payable to holders
        of OSB Common Stock Certificates.

                  (b)  If any FCB Common Stock Certificate is to be issued in
        a name other than that in which the OSB Common Stock Certificate
        surrendered in exchange therefor is registered, it shall be a
        condition of the issuance thereof that the OSB Common Stock
        Certificate so surrendered shall be properly endorsed (or accompanied
        by an appropriate instrument of transfer) and otherwise in proper
        form for transfer, and that the person requesting such exchange shall
        pay to the Exchange Agent in advance any transfer or other taxes
        required by reason of the issuance of an  FCB Common Stock
        Certificate in any name other than that of the registered holder of
        the OSB Common Stock Certificate surrendered, or required for any
        other reason, or shall establish to the satisfaction of the Exchange
        Agent that such tax has been paid or is not payable.

                  (c)  After the Effective Time, there shall be no transfers
        on the stock transfer books of OSB of the shares of OSB Common Stock
        which were issued and outstanding immediately prior to the Effective
        Time.  If, after the Effective Time, OSB Common Stock Certificates
        are presented for transfer to the Exchange Agent, they shall be
        canceled and exchanged for FCB Common Stock Certificates representing
        shares of FCB Common Stock as provided in this Article II.

                  (d)  Notwithstanding anything to the contrary contained
        herein, no certificates or scrip representing fractional shares of
        FCB Common Stock shall be issued upon the surrender for exchange of
        OSB Common Stock Certificates, no dividend or distribution with
        respect to FCB Common Stock shall be payable on or with respect to
        any fractional share, and such fractional share interests shall not
        entitle the owner thereof to vote or to any other rights of a
        shareholder of the Surviving Corporation.  In lieu of the issuance of
        any such fractional share, the Surviving Corporation shall pay to
        each former shareholder of OSB who otherwise would be entitled to
        receive such fractional share an amount in cash determined by
        multiplying (i) the average of the last sales price for FCB Common
        Stock as reported on The Nasdaq Stock Market for the twenty (20)
        trading days immediately preceding the fifth trading day prior to the
        Closing Date by (ii) the fraction of a share (rounded to the nearest
        tenth when expressed as an Arabic number) of FCB Common Stock to
        which such holder would otherwise be entitled to receive pursuant to
        Section 1.4. 

                  (e)  Any portion of the Conversion Fund that remains
        unclaimed by the shareholders of OSB for twelve (12) months after the
        Effective Time shall be paid to the Surviving Corporation.  Any
        shareholders of OSB who have not theretofore complied with this
        Article II shall thereafter look only to the Surviving Corporation
        for the issuance of certificates representing shares of FCB Common
        Stock and the payment of cash in lieu of any fractional shares and
        any unpaid dividends and distributions on the FCB Common Stock
        deliverable in respect of each share of OSB Common Stock such
        shareholder holds as determined pursuant to the Agreement and this
        Plan, in each case, without any interest thereon.  Notwithstanding
        the foregoing, none of FCB, OSB, the Exchange Agent or any other
        person shall be liable to any former holder of shares of OSB Common
        Stock, for any amount delivered in good faith to a public official
        pursuant to applicable abandoned property, escheat or similar laws.

                  (f)  In the event any OSB Common Stock Certificate shall
        have been lost, stolen or destroyed, upon the making of an affidavit
        of that fact by the person claiming such OSB Common Stock Certificate

   FCB Financial Corp.
   108 East Wisconsin Avenue
   Neenah, Wisconsin 54956

        Re:    Agreement and Plan of Merger, dated November __, 1996, 
               between FCB Financial Corp. and OSB Financial Corp.

   Gentlemen:

               Reference is made to the Agreement and Plan of Merger (the
   "Agreement") dated as of November __, 1996, by and between FCB Financial
   Corp., a Wisconsin corporation ("FCB"), and OSB Financial Corp., a
   Wisconsin corporation ("OSB"), providing for the merger of OSB with and
   into FCB (the "Merger") whereby FCB is the resulting corporation (the
   "Surviving Corporation").  Under the terms of the Agreement, all of the
   outstanding shares of common stock of OSB, $0.01 par value (the "OSB
   Common Stock"), will be converted into shares of common stock of FCB,
   $0.01 par value (the "FCB Common Stock").

               The undersigned has been advised that the issuance of shares
   of FCB Common Stock to the undersigned in connection with the Merger will
   be registered with the Securities and Exchange Commission (the "SEC")
   under the Securities Act of 1933, as amended (the "Securities Act"), on a
   Registration Statement on Form S-4 and that such registration will not
   cover any resale or other disposition of FCB Common Stock.  The
   undersigned also has been advised that the undersigned may be deemed to be
   an affiliate of the Surviving Corporation within the meaning of Rule 145
   of the rules and regulations of the SEC under the Securities Act and that
   the shares of FCB Common Stock acquired by the undersigned in connection
   with the Merger may only be disposed of in conformity with the provisions
   hereof.

               The undersigned represents and warrants to and agrees with
   OSB, FCB and the Surviving Corporation as follows:

               (a)     The undersigned shall not sell, exchange, transfer or
        otherwise dispose of any shares of FCB Common Stock received by the
        undersigned in the Merger except (i) at such time as a registration
        statement under the Securities Act covering sales of such FCB Common
        Stock by the undersigned is effective, (ii) within the limits, and in
        accordance with the applicable provisions of, Rule 145 under the
        Securities Act, or (iii) in a transaction which, in the opinion of
        counsel for the undersigned or as described in a "no-action" or
        interpretive letter from the staff of the SEC, in each case
        satisfactory to FCB, is not required to be registered under the
        Securities Act.  The undersigned acknowledges and agrees that FCB is
        under no obligation to register the sale, transfer or other
        disposition of such FCB Common Stock by the undersigned or on his or
        her behalf, or to take any other action necessary to make an
        exemption from registration available.

               (b)     FCB shall not be bound by any attempted sale of any
        shares of FCB Common Stock by the undersigned, and FCB's transfer
        agent shall be given an appropriate stop transfer order and shall not
        be required to register any such attempted sale, unless the sale has
        been effected in compliance with the terms of this Letter Agreement. 
        There will be placed on the certificate representing the shares of
        FCB Common Stock issued to the undersigned in the Merger, or any
        substitutions therefor, a restrictive legend stating in substance:

               "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
               PROVISIONS OF RULE 145(d), PROMULGATED UNDER THE SECURITIES
               ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED OR
               OTHERWISE DISPOSED OF WITHOUT COMPLIANCE WITH SAID RULE."

               (c)     The provisions of paragraphs (a) and (b) hereof shall
        also apply to any securities which may be paid as a dividend or
        otherwise distributed on or with respect to, or issued or delivered
        in exchange or substitution for, shares of FCB Common Stock received
        in the Merger by the undersigned.

               (d)     The undersigned does not have any present plan or
        intention to sell or otherwise dispose of shares of FCB Common Stock
        received by the undersigned in the Merger.  The undersigned
        undertakes to give prompt written notice to FCB, c/o James J.
        Rothenbach, President and Chief Executive Officer, if and as soon as,
        anytime after the date hereof, the undersigned has a plan or
        intention to sell or otherwise dispose of shares of FCB Common Stock
        received by the undersigned in the Merger.  [To be included only in
        those letters furnished by 5% shareholders]

               (e)     The undersigned has the capacity to enter into this
        Letter Agreement and to make the representations, warranties and
        agreements herein, and to perform the obligations of the undersigned
        hereunder.  This Letter Agreement constitutes a valid and binding
        obligation of the undersigned, enforceable against the undersigned in
        accordance with its terms.  This Letter Agreement shall be binding
        upon, and enforceable against, administrators, executors, personal
        representatives, donees, heirs, legatees and devisees of the
        undersigned, and any pledgee holding as collateral any shares of FCB
        Common Stock issued to the undersigned in the Merger, and any such
        person shall be required to acknowledge in writing the terms of this
        Letter Agreement. 

               FCB agrees that the stop transfer instructions and legend
   referred to in paragraph (c) hereof will be promptly removed upon (i) the
   sale, exchange, transfer or other disposition of the FCB Common Stock
   received in the Merger in full compliance with the provisions of this
   Letter Agreement or (ii) two (2) years after the effective date of the
   Merger, provided that, in the latter case, the undersigned is not an
   affiliate of FCB and adequate current public information with respect to
   the Surviving Corporation is then available, within the meaning of Rule
   144(c) under the Securities Act.

               This Letter Agreement shall terminate concurrently with any
   termination of the Agreement in accordance with its terms.

                                      Very truly yours,




                                      [Name]

                              EMPLOYMENT AGREEMENT

               NOW, THEREFORE, in consideration of the foregoing and of the
   respective covenants and agreements of the parties herein contained, it is
   agreed as follows:

                                    ARTICLE I
                                   EMPLOYMENT

   1.1  Term of Employment.

        The Bank hereby employs Executive for a period commencing on _______,
   1997 (the "Commencement Date") and terminating on October 31, 1999,
   subject to earlier termination as provided in Article II hereof.

   1.2  Duties of Executive.

        The Bank hereby employs Executive, and Executive hereby accepts
   employment with the Bank, upon the terms and conditions hereinafter set
   forth for the term of this Agreement.  Executive is employed by the Bank

   Company.  The services to be performed by the Executive shall include
   those normally performed by the Chairman of the Board of similar banking
   organizations and as directed by the Board of Directors of the Company and
   the Bank, respectively, which are not inconsistent with the foregoing. 
   Executive agrees to devote his full business time to the rendition of such
   services, subject to absences for customary vacations and for temporary
   illnesses.  The Company and the Bank each agree that during the term of
   this Agreement it will not reduce the Executive's current job title,
   status or responsibilities without the Executive's consent.  Furthermore,
   Executive shall not be required, without his express written consent, to
   be based anywhere other than within the Oshkosh-Neenah/Menasha-Appleton
   metropolitan area, except for reasonable business travel in connection
   with the business of the Company and the Bank.  During the term of this
   Agreement, Executive shall also serve as a director of the Company
   (subject to being elected by shareholders) and the Bank and shall be
   entitled to receive applicable director's fees (including fees for
   committee meetings) for service as a director of the Company and the Bank. 
      

   1.3  Compensation.

        The Bank agrees to compensate, and the Company agrees to cause the
   Bank to compensate, the Executive for his services hereunder during the
   term of this Agreement by payment of a salary at the annual rate of
   $139,200 in such monthly, semi-monthly or other payments as are from time
   to time applicable to other executive officers of the Bank.  The
   Executive's salary may be increased from time to time during the term of
   this Agreement in the sole discretion of the Board of Directors of the
   Bank, but Executive's salary shall not be reduced below the level then in
   effect.  In addition, Executive shall be entitled to participate in
   incentive compensation plans as may from time to time be established by
   the Company or the Bank on an equivalent basis as other executive officers
   of the Company or the Bank (but recognizing differences in
   responsibilities among executive officers).  All directors and committee
   meeting fees in respect to the Company and the Bank received by Executive
   shall be included along with his salary for purposes of computing any
   amount to which he may become entitled under any bonus or similar plan of
   the Company and the Bank.

   1.4  Benefits.

        (a)    Executive shall be provided the following additional benefits,
   (i) participation in any pension, profit-sharing, deferred compensation or
   other retirement plan, (ii) medical, dental and life insurance coverage
   consistent with coverages provided to other executive officers of the Bank
   (which initially will include a 30% co-pay by the Executive), (iii) the
   use of an automobile and membership or appropriate affiliation with a
   service club and a recreational club, (iv) reimbursement of business
   expenses reasonably incurred in connection with his employment and
   expenses incurred by his spouse when accompanying Executive, (v) paid
   vacations and sick leave in accordance with prevailing policies of the
   Bank, provided that allowed vacations shall in no event be less than five
   weeks per annum, and (vi) such other benefits as are provided to other
   executive officers of the Bank; provided that amounts allocated to
   Executive's personal use under clause (iii) above and additional charges
   for Executive's spouse pursuant to clause (iv) above shall be treated as
   taxable income to Executive in accordance with applicable Bank policies.

        (b)     If Executive shall become temporarily disabled or
   incapacitated to the extent that he is unable to perform the duties of
   Chairman of the Board of the Company or the Bank for three (3) consecutive
   months, he shall nevertheless be entitled to receive 100 percent of his
   compensation under Section 1.3 of this Agreement for the period of his
   disability up to three (3) months, less any amount paid to the Executive
   under any other disability program maintained by the Company or the Bank
   or disability insurance policy maintained for the benefit of Executive by
   the Company or the Bank.  Upon returning to active full-time employment,
   Executive's full compensation as set forth in this Agreement shall be
   reinstated.  In the event that Executive returns to active employment on
   other than a full-time basis with the approval of the Board of Directors
   of the Bank, then his compensation (as set forth in Section 1.3 of this
   Agreement) shall be reduced proportionately based upon the fraction of
   full-time employment devoted by Executive to his employment and
   responsibilities at the Bank and the Company.  But, if he is again unable
   to perform the duties of Chairman of the Board of the Company and the Bank
   hereunder due to disability or incapacity, he must have been engaged in
   active full-time employment for at least twelve (12) consecutive months
   immediately prior to such later absence or inability in order to qualify
   for the full or partial continuance of his salary under this Section (b). 

        (c)    It is the intention of the Company that, within 30 days after
   the date of this Agreement, the Company shall cause 10,000 non-tax-
   qualified stock options (exercisable for shares of the Company's common
   stock) to be granted to Executive.  The 10,000 stock options provided for
   in this Section 1.4(c) shall be granted by the personnel committee of the
   Company under the terms of the Company's 1993 Stock Option and Incentive
   Plan and shall vest ratably over a five year period beginning from the
   date of their grant and any unvested options shall vest immediately upon
   Executive's termination of employment on October 31, 1999.

   1.5  Covenant Not to Compete.

        Executive acknowledges that the Company and the Bank would be
   substantially damaged by an association of Executive with a depository
   institution that competes for customers with the Company and the Bank. 
   Without the consent of the Company, Executive shall not at any time during
   the term of this Agreement or Executive's employment by the Bank, and for
   a period of one year thereafter (regardless of the reason for
   termination), (i) on behalf of himself or as agent of any other person
   solicit any person who was a customer of the Company or the Bank or any of
   their subsidiaries during the two year period prior to the termination of
   this Agreement or Executive's employment hereunder for the purpose of
   offering the same products or rendering the same services to such customer
   as were provided or proposed to be provided by the Company or the Bank or
   any of their subsidiaries to such customer as of the time of termination
   of Executive's employment, (ii) directly or indirectly, on Executive's
   behalf or in the service or on the behalf of others, render or be retained
   to render similar services as described in Section 1.2 hereof, whether as
   an officer, partner, trustee, consultant, or employee for any depository
   institution, which has a banking office located within 10 miles of any
   office of the Bank or any banking office of the Company in existence as of
   the Commencement Date, provided, however, that Executive shall not be
   deemed to have breached this undertaking if (a) he renders services
   otherwise prohibited by this paragraph (ii) for a depository institution
   which has its home office located outside of the Wisconsin counties of
   Winnebago and Outagamie and he renders such services from a full-service
   banking office of such depository institution which is located outside
   these same Wisconsin counties, or (b) his sole relationship with any other
   such entity consists of his holding, directly or indirectly, an equity
   interest in such entity not greater than three percent (3%) of such
   entity's outstanding equity interest, or (iii) actively induce or solicit
   any employees of the Company or the Bank to leave such employ.  For
   purposes of this Section 1.5, "person" shall include any individual,
   corporation, partnership, trust, firm, proprietorship, venture or other
   entity of any nature whatsoever.

                                   ARTICLE II
                            TERMINATION OF EMPLOYMENT

   2.1  Voluntary Termination of Employment by Executive.

        Executive may terminate his employment hereunder at any time for any
   reason upon giving the Bank written notice, at least ninety (90) days
   prior to termination of employment.  Upon such termination, Executive
   shall be entitled to receive Executive's theretofore unpaid base salary in
   effect at the date such written notice is given for the period of
   employment up to the date of termination, and  Executive and his spouse
   and dependents will be entitled to further medical coverage, at his and/or
   their expense, to the extent required by COBRA.

   2.2  Termination of Employment for Death.

        If Executive's employment is terminated by reason of Executive's
   death, then Executive's personal representative shall be entitled to
   receive Executive's theretofore unpaid base salary for the period of
   employment up to the date of death.  Executive's spouse and dependent
   children shall continue to be entitled, at the expense of the Bank
   (subject to then existing co-payment features applicable under the Bank's
   medical insurance plan) if it is an insured plan, to further medical
   coverage to the extent permitted by COBRA; provided that, if the Bank's
   plan is not insured, the Bank will pay to Executive's spouse an additional
   monthly death benefit during the applicable COBRA period, based upon COBRA
   rates in effect at the time of Executive's death, in an amount equal to
   the COBRA rate plus taxes due on such cash payment; provided further that
   this benefit shall cease if the spouse and dependents cease to be eligible
   for COBRA coverage.

   2.3  Termination of Employment for Disability.

        If Executive becomes Totally and Permanently Disabled (as defined

   than 5 days before the effective date thereof.  If Executive's employment
   and this Agreement are terminated pursuant to this Section 2.3, the Bank
   shall pay to Executive his theretofore unpaid base salary for the period
   of employment up to the date of termination, and the Company and the Bank
   shall have no further obligations to Executive under this Agreement,
   except for any COBRA obligations.  The Executive is Totally and
   Permanently Disabled for purposes of this Section 2.3 if he is disabled or
   incapacitated to the extent that he is unable to perform the duties of
   Chairman of the Board of the Company or the Bank for more than three (3)
   consecutive months, and such disability or incapacity (i) is expected to
   continue for more than three (3) additional months as certified by a
   medical doctor of the Company's choosing which is not contradicted by a
   doctor of the Executive's choosing or (ii) shall have in fact continued
   for more than three (3) additional months.

   2.4  Termination of Employment by the Company for Just Cause.

        The Bank may terminate Executive's employment hereunder for Just
   Cause (as such term is defined below), in which case the Executive shall
   be entitled to receive Executive's theretofore unpaid base salary for the
   period of employment up to the date of termination, but shall not be
   entitled to any compensation or employment benefits pursuant to this
   Agreement for any period after the date of termination, or the
   continuation of any benefits except as may be required by law, including,
   at his own expense, COBRA.

        "Just Cause" shall mean personal dishonesty, incompetence, willful
   misconduct or breach of a fiduciary duty involving personal profit in the
   performance of his duties under this Agreement, intentional failure to
   perform stated duties (provided that such nonperformance has continued for
   10 days after the Bank has given written notice of such nonperformance to
   the Executive and its intention to terminate Executive's employment
   hereunder because of such nonperformance), willful violation of any law,
   rule or regulation (other than a law, rule or regulation relating to a
   traffic violation or similar offense), final cease-and-desist order,
   termination under the provisions of Section 2.7(b) and (c) or material
   breach of any provision of this Agreement.  

   2.5  Termination of Employment by the Bank Without Cause.

        The Bank may terminate Executive's employment hereunder without
   cause, in which case the Executive shall receive (a) his base salary under
   Section 1.3 hereof through the then remaining term of employment under
   Section 1.1, (b) his theretofore unpaid base salary for the period of
   employment up to the date of termination, (c) medical, dental and life
   insurance through the then remaining term of employment under Section 1.1
   consistent with the terms and conditions set forth in Section 1.4, to the
   extent the same can be provided under the insurance arrangements of the
   Bank in effect at the time of termination, (d) any other benefits to which
   Executive is entitled by law or the specific terms of the Bank's policies
   in effect at the time of termination of employment and (e) an amount equal
   to the product of  the Bank's annual aggregate contribution, for the
   benefit of the Executive in the fiscal year preceding termination, to all
   qualified retirement plans in which the Executive participated multiplied
   by the number of years in the term of employment under Section 1.1.  The
   benefit in (e) under this Section 2.5 shall be in addition to any benefit
   payable from any qualified or non-qualified plans or programs maintained
   by the Company or the Bank at the time of termination.  If the Bank's
   medical and dental plans are not insured, the medical and dental benefit
   in (c) shall be accomplished by the Bank paying to Executive an additional
   cash amount equal to the COBRA premium for such coverage, plus taxes on
   such amount, so that Executive may purchase the coverage on an after-tax
   basis.

   2.6  Definition of Termination of Employment.

        The terms "termination" or  "involuntarily terminated" in this
   Agreement shall refer to the termination of the employment of Executive by
   the Bank without his express written consent.  In addition, for purposes
   of this Agreement, a material diminution  or interference with the
   Executive's duties, responsibilities and benefits as Chairman of the Board
   of the Company or the Bank shall be deemed and shall constitute an
   involuntary termination of employment to the same extent as express notice
   of such involuntary termination.  By way of example and not by way of
   limitation, any of the following actions, if unreasonable or materially
   adverse to the Executive shall constitute such diminution or interference
   unless consented to in writing by the Executive: (1) a change in the
   principal work place of the Executive to a location outside a twenty-five
   mile radius from the Company's headquarters at 420 South Koeller Street,
   Oshkosh, Wisconsin; (2) a material reduction in the secretarial or other
   administrative support of the Executive; (3) a material demotion of the
   Executive, a material reduction in the number or seniority of other
   Company or Bank personnel reporting to the Executive, or a reduction in
   the frequency with which, or in the nature of the matters with respect to
   which, such personnel are to report to the Executive, other than as part
   of a Company-wide or Bank-wide reduction in staff; and (4) a reduction or
   adverse change in the salary,  perquisites, benefits, contingent benefits
   or vacation time which had theretofore been provided to the Executive,
   other than as part of an overall program applied uniformly and with
   equitable effect to all executive officers of the Company or the Bank.

   2.7  Termination or Suspension of Employment as Required by Law.

        Notwithstanding anything in this Agreement to the contrary, the
   following provisions shall limit the obligation of the Bank to continue
   employing Executive, but only to the extent required by the applicable
   regulations of the OTS (12 C.F.R. Section  563.39), or similar succeeding
   regulations:

        (a)    If the Executive is suspended and/or temporarily prohibited
   from participating in the conduct of the Bank's affairs by a notice served
   under Section 8(e)(3) or (g)(1) of the Federal Deposit Insurance Act (12
   U.S.C.  Section  1818(e)(3) and (g)(1)) the Bank's obligations under this
   Agreement shall be suspended as of the date of service of notice, unless
   stayed by appropriate proceedings.  If the charges in the notice are
   dismissed, the Bank may in its discretion (i) pay the Executive all or
   part of the compensation withheld while its contract obligations hereunder
   were suspended and (ii) reinstate (in whole or in part) any of its
   obligations which were suspended.

        (b)    If the Executive is removed and/or permanently prohibited from
   participating in the conduct of the Bank's affairs by an order issued
   under Section 8(e)(4) or (g)(1) of the Federal Deposit Insurance Act (12
   U.S.C. Section  1818(e)(4) or (g)(1)) all obligations of the Bank under
   this Agreement shall terminate as of the effective date of the order.

        (c)    If the Bank is in default (as defined in Section 3(x)(1) of
   the Federal Deposit Insurance Act), the obligation to Executive hereunder
   shall terminate as of the date of default.

        (d)    All obligations under this Agreement may be terminated:  (i)
   by the Director of the Office of Thrift Supervision (the "Director") or
   his or her designee at the time the Federal Deposit Insurance Company
   enters into an agreement to provide assistance to or on behalf of the Bank
   under the authority contained in Section 13(c) of the Federal Deposit
   Insurance Act and (ii) by the Director, or his or her designee at the time
   the Director or such designee approves a supervisory merger to resolve
   problems related to operation of the Bank or when the Bank is determined
   by the Director to be in an unsafe or unsound condition.

        (e)    Termination pursuant to subparagraph (d) of this Section 2.7
   shall be treated as a termination by the Bank without cause entitling
   Executive to benefits payable under Section 2.5.  Termination pursuant to
   subparagraph (a), (b) or (c) shall be treated as a termination for Just
   Cause under Section 2.4.  Termination under this Section 2.7 shall not
   affect other rights hereunder which are vested at the time of termination.

   2.8  Limitation on Termination or Disability Pay.

        Any payments made to the Executive pursuant to this Agreement or
   otherwise are subject to and conditioned upon their compliance with 12

   the Bank contesting the validity or enforceability of this Agreement,

   that any dispute may otherwise be settled in favor of the Executive.  The
   Executive shall be entitled to receive interest thereon for the period of
   any delay in payment from the date such payment was due at the rate
   determined by adding two hundred basis points to the six-month Treasury
   Bill rate.

                                   ARTICLE IV

   its subsidiaries and that the disclosure to, or the use of such
   information by, and business in competition with the Company, the Bank or

   notice to express in writing to Executive its position with respect
   thereof and in the event such writing shall not be given to Executive,

                                    ARTICLE I
                                   EMPLOYMENT

   1.1  Term of Employment.

   employment with the Bank, upon the terms and conditions hereinafter set
   forth for the term of this Agreement.  Executive is employed by the Bank
   to perform the duties of Vice President, Treasurer and Chief Financial

   Financial Officer of similar banking organizations and as directed by the
   Board of Directors of the Company and the Bank, respectively, which are
   not inconsistent with the foregoing.  Executive agrees to devote his full
   business time to the rendition of such services, subject to absences for
   customary vacations and for temporary illnesses.  The Company and the Bank
   each agree that during the term of this Agreement it will not reduce the
   Executive's current job title, status or responsibilities without the
   Executive's consent.  Furthermore, Executive shall not be required,
   without his express written consent, to be based anywhere other than
   within the Oshkosh-Neenah/Menasha-Appleton metropolitan area, except for
   reasonable business travel in connection with the business of the Company
   and the Bank.

   1.3  Compensation.

        The Bank agrees to compensate, and the Company agrees to cause the
   Bank to compensate, the Executive for his services hereunder during the
   term of this Agreement by payment of a salary at the annual rate of
   $75,000 in such monthly, semi-monthly or other payments as are from time
   to time applicable to other executive officers of the Bank.  The
   Executive's salary may be increased from time to time during the term of
   this Agreement in the sole discretion of the Board of Directors of the
   Bank, but Executive's salary shall not be reduced below the level then in
   effect.  In addition, Executive shall be entitled to participate in
   incentive compensation plans as may from time to time be established by
   the Company or the Bank on an equivalent basis as other executive officers
   of the Company or the Bank (but recognizing differences in
   responsibilities among executive officers).

   1.4  Benefits.

        (a)    Executive shall be provided the following additional benefits,
   (i) participation in any pension, profit-sharing, deferred compensation or
   other retirement plan, (ii) medical, dental and life insurance coverage
   consistent with coverages provided to other executive officers of the Bank
   (which initially will include a 30% co-pay by the Executive), (iii)
   membership or appropriate affiliation with a recreational club, (iv)
   reimbursement of business expenses reasonably incurred in connection with
   his employment and expenses incurred by his spouse when accompanying
   Executive, (v) paid vacations and sick leave in accordance with prevailing
   policies of the Bank, provided that allowed vacations shall in no event be
   less than three weeks per annum, and (vi) such other benefits as are
   provided to other executive officers of the Bank; provided that amounts
   allocated to Executive's personal use under clause (iii) above and
   additional charges for Executive's spouse pursuant to clause (iv) above
   shall be treated as taxable income to Executive in accordance with
   applicable Bank policies.

        (b)     If Executive shall become temporarily disabled or
   incapacitated to the extent that he is unable to perform the duties of
   Vice President, Treasurer and Chief Financial Officer of the Company or
   the Bank for three (3) consecutive months, he shall nevertheless be
   entitled to receive 100 percent of his compensation under Section 1.3 of
   this Agreement for the period of his disability up to three (3) months,
   less any amount paid to the Executive under any other disability program
   maintained by the Company or the Bank or disability insurance policy
   maintained for the benefit of Executive by the Company or the Bank.  Upon
   returning to active full-time employment, Executive's full compensation as
   set forth in this Agreement shall be reinstated.  In the event that
   Executive returns to active employment on other than a full-time basis
   with the approval of the Board of Directors of the Bank, then his
   compensation (as set forth in Section 1.3 of this Agreement) shall be
   reduced proportionately based upon the fraction of full-time employment
   devoted by Executive to his employment and responsibilities at the Bank
   and the Company.  But, if he is again unable to perform the duties of Vice
   President, Treasurer and Chief Financial Officer of the Company and the
   Bank hereunder due to disability or incapacity, he must have been engaged
   in active full-time employment for at least twelve (12) consecutive months
   immediately prior to such later absence or inability in order to qualify
   for the full or partial continuance of his salary under this Section (b). 

        (c)    It is the intention of the Company that, within 30 days after
   the date of this Agreement, the Company shall cause 7,500 non-tax-
   qualified stock options (exercisable for shares of the Company's common
   stock) to be granted to Executive.  The 7,500 stock options provided for
   in this Section 1.4(c) shall be granted by the personnel committee of the
   Company under the terms of the Company's 1993 Stock Option and Incentive
   Plan and shall vest ratably over a five year period beginning from the
   date of their grant.

   1.5  Covenant Not to Compete.

        Executive acknowledges that the Company and the Bank would be
   substantially damaged by an association of Executive with a depository
   institution that competes for customers with the Company and the Bank. 
   Without the consent of the Company, Executive shall not at any time during
   the term of this Agreement or Executive's employment by the Bank, and for
   a period of one year thereafter (regardless of the reason for
   termination), (i) on behalf of himself or as agent of any other person
   solicit any person who was a customer of the Company or the Bank or any of
   their subsidiaries during the two year period prior to the termination of
   this Agreement or Executive's employment hereunder for the purpose of
   offering the same products or rendering the same services to such customer
   as were provided or proposed to be provided by the Company or the Bank or
   any of their subsidiaries to such customer as of the time of termination
   of Executive's employment, or (ii) actively induce or solicit any
   employees of the Company or the Bank to leave such employ.  For purposes
   of this Section 1.5, "person" shall include any individual, corporation,
   partnership, trust, firm, proprietorship, venture or other entity of any
   nature whatsoever.

        Executive may terminate his employment hereunder at any time for any
   reason upon giving the Bank written notice, at least ninety (90) days
   prior to termination of employment.  Upon such termination, Executive
   shall be entitled to receive Executive's theretofore unpaid base salary in
   effect at the date such written notice is given for the period of
   employment up to the date of termination, and  Executive and his spouse
   and dependents will be entitled to further medical coverage, at his and/or
   their expense, to the extent required by COBRA.

   2.2  Termination of Employment for Death.

        If Executive's employment is terminated by reason of Executive's
   death, then Executive's personal representative shall be entitled to
   receive Executive's theretofore unpaid base salary for the period of
   employment up to the date of death.  Executive's spouse and dependent
   children shall continue to be entitled, at the expense of the Bank
   (subject to then existing co-payment features applicable under the Bank's
   medical insurance plan) if it is an insured plan, to further medical
   coverage to the extent permitted by COBRA; provided that, if the Bank's
   plan is not insured, the Bank will pay to Executive's spouse an additional
   monthly death benefit during the applicable COBRA period, based upon COBRA
   rates in effect at the time of Executive's death, in an amount equal to
   the COBRA rate plus taxes due on such cash payment; provided further that
   this benefit shall cease if the spouse and dependents cease to be eligible
   for COBRA coverage.

   2.3  Termination of Employment for Disability.

        If Executive becomes Totally and Permanently Disabled (as defined
   below) during the term of this Agreement, the Bank may terminate
   Executive's employment and this Agreement, except Section 1.5 and Article
   IV hereof, by giving Executive written notice of such termination not less
   than 5 days before the effective date thereof.  If Executive's employment
   and this Agreement are terminated pursuant to this Section 2.3, the Bank
   shall pay to Executive his theretofore unpaid base salary for the period
   of employment up to the date of termination, and the Company and the Bank
   shall have no further obligations to Executive under this Agreement,
   except for any COBRA obligations.  The Executive is Totally and
   Permanently Disabled for purposes of this Section 2.3 if he is disabled or
   incapacitated to the extent that he is unable to perform the duties of
   Vice President, Treasurer and Chief Financial Officer of the Company or
   the Bank for more than three (3) consecutive months, and such disability
   or incapacity (i) is expected to continue for more than three (3)
   additional months as certified by a medical doctor of the Company's
   choosing which is not contradicted by a doctor of the Executive's choosing
   or (ii) shall have in fact continued for more than three (3) additional
   months.

   2.4  Termination of Employment by the Company for Just Cause.

        The Bank may terminate Executive's employment hereunder for Just
   Cause (as such term is defined below), in which case the Executive shall
   be entitled to receive Executive's theretofore unpaid base salary for the
   period of employment up to the date of termination, but shall not be
   entitled to any compensation or employment benefits pursuant to this
   Agreement for any period after the date of termination, or the
   continuation of any benefits except as may be required by law, including,
   at his own expense, COBRA.

        "Just Cause" shall mean personal dishonesty, incompetence, willful
   misconduct or breach of a fiduciary duty involving personal profit in the
   performance of his duties under this Agreement, intentional failure to
   perform stated duties (provided that such nonperformance has continued for
   10 days after the Bank has given written notice of such nonperformance to
   the Executive and its intention to terminate Executive's employment
   hereunder because of such nonperformance), willful violation of any law,
   rule or regulation (other than a law, rule or regulation relating to a
   traffic violation or similar offense), final cease-and-desist order,
   termination under the provisions of Section 2.7(b) and (c) or material
   breach of any provision of this Agreement.  

   2.5  Termination of Employment by the Bank Without Cause.

        The Bank may terminate Executive's employment hereunder without
   cause, in which case the Executive shall receive (a) his base salary under
   Section 1.3 hereof through the then remaining term of employment under
   Section 1.1, (b) his theretofore unpaid base salary for the period of
   employment up to the date of termination, (c) medical, dental and life
   insurance through the then remaining term of employment under Section 1.1
   consistent with the terms and conditions set forth in Section 1.4, to the
   extent the same can be provided under the insurance arrangements of the
   Bank in effect at the time of termination, (d) any other benefits to which
   Executive is entitled by law or the specific terms of the Bank's policies
   in effect at the time of termination of employment and (e) an amount equal
   to the product of  the Bank's annual aggregate contribution, for the
   benefit of the Executive in the fiscal year preceding termination, to all
   qualified retirement plans in which the Executive participated multiplied
   by the number of years in the initial term of employment under Section
   1.1.  The benefit in (e) under this Section 2.5 shall be in addition to
   any benefit payable from any qualified or non-qualified plans or programs
   maintained by the Company or the Bank at the time of termination.  If the
   Bank's medical and dental plans are not insured, the medical and dental
   benefit in (c) shall be accomplished by the Bank paying to Executive an
   additional cash amount equal to the COBRA premium for such coverage, plus
   taxes on such amount, so that Executive may purchase the coverage on an
   after-tax basis.

   2.6  Termination of Employment Due to Change in Control.

        (a)    If, at any time after the date hereof, a "Change in Control"
   (as hereinafter defined) occurs and within eighteen (18) months thereafter
   Executive's appointment as Vice President, Treasurer and Chief Financial
   Officer of the Company or his employment as Vice President, Treasurer and
   Chief Financial Officer of the Bank is involuntarily terminated (other
   than for Just Cause pursuant to Section 2.4) then the Executive shall be
   entitled to the benefits provided below.

               (i)     The Company shall promptly pay, or cause the Bank to
   pay, to the Executive an amount equal to the product of 2.0 times the
   Executive's "base amount" as defined in Section 280G(b)(3) of the Code
   (such "base amount" to be derived from Executive's compensation paid by
   the Company and the Bank).

               (ii)     During the term of this Agreement set forth in
   paragraph 1.1 (including any renewal term), the Executive, his dependents,
   beneficiaries and estate shall continue to be covered under all employee
   benefit plans of the Company and the Bank, including without limitation
   the Company's and the Bank's pension and retirement plans, life insurance
   and health insurance as if the Executive was still employed by the Bank
   during such period under this Agreement; provided that coverage under the
   medical and dental plans of the Company and the Bank shall be handled as
   set forth in Section 2.5 above.

               (iii)   If and to the extent that benefits or services credit
   for benefits under Section 2.6(a)(ii) above shall not be payable or
   provided under any such plans to the Executive, his dependents,
   beneficiaries and estate, by reason of his no longer being an employee of
   the Bank as a result of termination of employment, the Company shall
   itself, or shall cause the Bank to, pay or provide for payment of such
   benefits and service credit for benefits to the Executive, his dependents,
   beneficiaries and estate.  Any such payment relating to retirement shall
   commence on a date selected by the Executive which must be a date on which
   payments under the Company or Bank's qualified pension plan or successor
   plan may commence.

        (b)    (i)     Anything in this Agreement to the contrary
   notwithstanding, it is the intention of the Company, the Bank and the
   Executive that no portion of any payment under this Agreement, or payments
   to or for the benefit of the Executive under any other agreement or plan,
   be deemed an "Excess Parachute Payment" as defined in Section 280G of the
   Code, or its successors.  It is agreed that the present value of any
   payment to or for the benefit of the Executive in the nature of
   compensation, receipt of which is contingent on the occurrence of a Change
   in Control, and to which Section 280G of the Code applies (in the
   aggregate "Total Payments") shall not exceed an amount equal to one dollar
   less than the maximum amount that the Company and the Bank may pay without
   loss of deduction under Section 280(G)(a) of the Code.  Present value for
   purposes of this Agreement shall be calculated in accordance with Section
   280G(d)(4) of the Code.  Within sixty days (60) following the earlier of
   (1) the giving of notice of termination of employment or (2) the giving of
   notice by the Company to the Executive of its belief that there is a
   payment or benefit due the Executive, the Company, at the Company's
   expense, shall obtain the opinion of the Company's public accounting firm
   (the "Accounting Firm"), which opinion need not be unqualified, which sets
   forth: (a) the amount of the Base Period Income of the Executive (as
   defined in Code Section 280G), (b) the present value of Total Payments and
   (c) the amount and present value of any Excess Parachute Payments.  In the
   event that such opinion determines that there would be an Excess Parachute
   Payment, the payment hereunder shall be modified, reduced or eliminated as
   specified by the Executive in writing delivered to the Company within
   thirty (30) days of his receipt of such opinion or, if the Executive fails
   to so notify the Company, then as the Company shall reasonably determine,
   so that under the bases of calculation set forth in such opinion there
   will be no Excess Parachute Payment.  In the event that the provisions of
   Sections 280G and 4999 of the Code are repealed without succession, this
   Section shall be of no further force or effect.

               (ii)    In the event that the Accounting Firm is serving as
   accountant or auditor for the individual, entity or group effecting the
   Change in Control, the Executive shall appoint another nationally
   recognized public accounting firm to make the determinations required
   hereunder (which accounting firm shall then be referred to as the
   Accounting Firm under Section 2.6(b)).  All fees and expenses of the
   Accounting Firm shall be borne solely by the Company.  Any determination
   by the Accounting Firm shall be binding upon the Company and the
   Executive.

        (c)    For purposes of Section 2.6 of this Agreement, a "Change in
   Control" shall be deemed to have occurred if:

               (i)     a third person, including a "group" as defined in
   Section 13(d)(3) of the Securities Exchange Act of 1934 (as in effect on
   the date hereof), becomes the beneficial owner of shares of the Company
   having 20% or more of the total number of votes that may be cast for the
   election of directors of the Company, including for this purpose any
   shares beneficially owned by such third person or group as of the date
   hereof; or

               (ii)    as the result of, or in connection with, any cash
   tender or exchange offer, merger or other business combination, sale of
   assets or contested election, or any combination of the foregoing
   transactions (a "Transaction"), the persons who were directors of the
   Company before the Transaction shall cease to constitute a majority of the
   Board of Directors of the Company or any successor to the Company. (In the
   event of any reorganization involving the Company in a transaction
   initiated by the Company in which the shareholders of the Company
   immediately prior to such reorganization become the shareholders of a
   successor or ultimate parent company of the Company resulting from such
   reorganization and the persons who were directors of the Company
   immediately prior to such reorganization constitute a majority of the
   Board of Directors of such successor or ultimate parent, no "Change in
   Control" shall be deemed to have taken place solely by reason of such
   reorganization, notwithstanding the fact that the Company may have become
   the wholly-owned subsidiary of another Company in such reorganization and
   the Board of Directors thereof may have been reconstituted, and thereafter
   the term "Company" for purposes of this paragraph shall refer to such
   successor or ultimate parent company.); or

               (iii)   a third person, including a "group" as defined in
   Section 13(d)(3) of the Securities Exchange Act of 1934 (as in effect on
   the date hereof), acquires control, as defined in 12 C.F.R. Section 
   574.4, or any successor regulation, of the Company which would require the
   filing of an application for acquisition of control or notice of change in
   control in a manner set forth in 12 C.F.R. Section  574.3, or any
   successor regulation; or

               (iv)    The terms "termination" or  "involuntarily terminated"
   in this Agreement shall refer to the termination of the employment of
   Executive by the Bank without his express written consent.  In addition,
   for purposes of this Agreement, a material diminution  or interference
   with the Executive's duties, responsibilities and benefits as Vice
   President, Treasurer and Chief Financial Officer of the Company or the
   Bank shall be deemed and shall constitute an involuntary termination of
   employment to the same extent as express notice of such involuntary
   termination.  By way of example and not by way of limitation, any of the
   following actions, if unreasonable or materially adverse to the Executive
   shall constitute such diminution or interference unless consented to in
   writing by the Executive: (1) a change in the principal work place of the
   Executive to a location outside a twenty-five mile radius from the
   Company's headquarters at 420 South Koeller Street, Oshkosh, Wisconsin;
   (2) a material reduction in the secretarial or other administrative
   support of the Executive; (3) a material demotion of the Executive, a
   material reduction in the number or seniority of other Company or Bank
   personnel reporting to the Executive, or a reduction in the frequency with
   which, or in the nature of the matters with respect to which, such
   personnel are to report to the Executive, other than as part of a Company-
   wide or Bank-wide reduction in staff; and (4) a reduction or adverse
   change in the salary,  perquisites, benefits, contingent benefits or
   vacation time which had theretofore been provided to the Executive, other
   than as part of an overall program applied uniformly and with equitable
   effect to all executive officers of the Company or the Bank.

   2.7  Termination or Suspension of Employment as Required by Law.

        Notwithstanding anything in this Agreement to the contrary, the
   following provisions shall limit the obligation of the Bank to continue
   employing Executive, but only to the extent required by the applicable
   regulations of the OTS (12 C.F.R. Section  563.39), or similar succeeding
   regulations:

        (a)    If the Executive is suspended and/or temporarily prohibited
   from participating in the conduct of the Bank's affairs by a notice served
   under Section 8(e)(3) or (g)(1) of the Federal Deposit Insurance Act (12
   U.S.C.  Section  1818(e)(3) and (g)(1)) the Bank's obligations under this
   Agreement shall be suspended as of the date of service of notice, unless
   stayed by appropriate proceedings.  If the charges in the notice are
   dismissed, the Bank may in its discretion (i) pay the Executive all or
   part of the compensation withheld while its contract obligations hereunder
   were suspended and (ii) reinstate (in whole or in part) any of its
   obligations which were suspended.

        (b)    If the Executive is removed and/or permanently prohibited from
   participating in the conduct of the Bank's affairs by an order issued
   under Section 8(e)(4) or (g)(1) of the Federal Deposit Insurance Act (12
   U.S.C. Section  1818(e)(4) or (g)(1)) all obligations of the Bank under
   this Agreement shall terminate as of the effective date of the order.

        (c)    If the Bank is in default (as defined in Section 3(x)(1) of
   the Federal Deposit Insurance Act), the obligation to Executive hereunder
   shall terminate as of the date of default.

        (d)    All obligations under this Agreement may be terminated:  (i)
   by the Director of the Office of Thrift Supervision (the "Director") or
   his or her designee at the time the Federal Deposit Insurance Company
   enters into an agreement to provide assistance to or on behalf of the Bank
   under the authority contained in Section 13(c) of the Federal Deposit
   Insurance Act and (ii) by the Director, or his or her designee at the time
   the Director or such designee approves a supervisory merger to resolve
   problems related to operation of the Bank or when the Bank is determined
   by the Director to be in an unsafe or unsound condition.

        (e)    Termination pursuant to subparagraph (d) of this Section 2.7
   shall be treated as a termination by the Bank without cause entitling
   Executive to benefits payable under Section 2.5.  Termination pursuant to
   subparagraph (a), (b) or (c) shall be treated as a termination for Just
   Cause under Section 2.4.  Termination under this Section 2.7 shall not
   affect other rights hereunder which are vested at the time of termination.

   2.8  Limitation on Termination or Disability Pay.

        Any payments made to the Executive pursuant to this Agreement or
   otherwise are subject to and conditioned upon their compliance with 12
   U.S.C. Section  1828(k) and any regulations promulgated thereunder.


                                   ARTICLE III
                             LEGAL FEES AND EXPENSES

        The Company shall pay, or shall cause the Bank to pay, all legal fees
   and expenses which the Executive may incur as a result of the Company or
   the Bank contesting the validity or enforceability of this Agreement,
   provided that the Executive is the prevailing party in such contest or
   that any dispute may otherwise be settled in favor of the Executive.  The
   Executive shall be entitled to receive interest thereon for the period of
   any delay in payment from the date such payment was due at the rate
   determined by adding two hundred basis points to the six-month Treasury
   Bill rate.

                                   ARTICLE IV
                                 CONFIDENTIALITY

        Executive acknowledges that he now has, and in the course of his
   employment will have, access to important and confidential information
   regarding the business and services of the Company, the Bank and their
   subsidiaries, as well as similar information regarding OSB Financial and
   its subsidiaries, and that the disclosure to, or the use of such
   information by, and business in competition with the Company, the Bank or
   their subsidiaries shall result in substantial and undeterminable harm to
   the Company, the Bank and their subsidiaries.  In order to protect the
   Company, the Bank and their subsidiaries against such harm and from unfair
   competition, Executive agrees with the Company and the Bank that while
   employed by the Bank and at any time thereafter, Executive will not
   disclose, communicate or divulge to anyone, or use in any manner adverse
   to the Company, the Bank or their subsidiaries any information concerning
   customers, methods of business, financial information or other
   confidential information of the Company, the Bank, their subsidiaries or
   similar information regarding OSB Financial and its subsidiaries, except
   for information as is in the public domain or ascertainable through common
   sources of public information (otherwise than as a result of any breach of
   this covenant by Executive).

   notice to express in writing to Executive its position with respect
   thereof and in the event such writing shall not be given to Executive,

   employment or otherwise, nor shall the amount of any payment or benefit

   the Bank except in connection with a merger involving the Company or the

   be performed by the Executive shall include those normally performed by
   the Vice President - Retail Lending and Secretary of similar banking
   organizations and as directed by the Board of Directors of the Company and
   the Bank, respectively, which are not inconsistent with the foregoing. 
   Executive agrees to devote his full business time to the rendition of such
   services, subject to absences for customary vacations and for temporary
   illnesses.  The Company and the Bank each agree that during the term of
   this Agreement it will not reduce the Executive's current job title,
   status or responsibilities without the Executive's consent.  Furthermore,
   Executive shall not be required, without his express written consent, to
   be based anywhere other than within the Oshkosh-Neenah/Menasha-Appleton
   metropolitan area, except for reasonable business travel in connection
   with the business of the Company and the Bank.

   1.3  Compensation.

        The Bank agrees to compensate, and the Company agrees to cause the
   Bank to compensate, the Executive for his services hereunder during the
   term of this Agreement by payment of a salary at the annual rate of
   $70,000 in such monthly, semi-monthly or other payments as are from time
   to time applicable to other executive officers of the Bank.  The
   Executive's salary may be increased from time to time during the term of
   this Agreement in the sole discretion of the Board of Directors of the
   Bank, but Executive's salary shall not be reduced below the level then in
   effect.  In addition, Executive shall be entitled to participate in
   incentive compensation plans as may from time to time be established by
   the Company or the Bank on an equivalent basis as other executive officers
   of the Company or the Bank (but recognizing differences in
   responsibilities among executive officers).

   1.4  Benefits.

        (a)    Executive shall be provided the following additional benefits,
   (i) participation in any pension, profit-sharing, deferred compensation or
   other retirement plan, (ii) medical, dental and life insurance coverage
   consistent with coverages provided to other executive officers of the Bank
   (which initially will include a 30% co-pay by the Executive), (iii)
   membership or appropriate affiliation with a recreational club, (iv)
   reimbursement of business expenses reasonably incurred in connection with
   his employment and expenses incurred by his spouse when accompanying
   Executive, (v) paid vacations and sick leave in accordance with prevailing
   policies of the Bank, provided that allowed vacations shall in no event be
   less than three weeks per annum, and (vi) such other benefits as are
   provided to other executive officers of the Bank; provided that amounts
   allocated to Executive's personal use under clause (iii) above and
   additional charges for Executive's spouse pursuant to clause (iv) above
   shall be treated as taxable income to Executive in accordance with
   applicable Bank policies.

        (b)     If Executive shall become temporarily disabled or
   incapacitated to the extent that he is unable to perform the duties of
   Vice President - Retail Lending and Secretary of the Company or the Bank
   for three (3) consecutive months, he shall nevertheless be entitled to
   receive 100 percent of his compensation under Section 1.3 of this
   Agreement for the period of his disability up to three (3) months, less
   any amount paid to the Executive under any other disability program
   maintained by the Company or the Bank or disability insurance policy
   maintained for the benefit of Executive by the Company or the Bank.  Upon
   returning to active full-time employment, Executive's full compensation as
   set forth in this Agreement shall be reinstated.  In the event that
   Executive returns to active employment on other than a full-time basis
   with the approval of the Board of Directors of the Bank, then his
   compensation (as set forth in Section 1.3 of this Agreement) shall be
   reduced proportionately based upon the fraction of full-time employment
   devoted by Executive to his employment and responsibilities at the Bank
   and the Company.  But, if he is again unable to perform the duties of Vice
   President - Retail Lending and Secretary of the Company and the Bank
   hereunder due to disability or incapacity, he must have been engaged in
   active full-time employment for at least twelve (12) consecutive months
   immediately prior to such later absence or inability in order to qualify
   for the full or partial continuance of his salary under this Section (b). 

        (c)    It is the intention of the Company that, within 30 days after
   the date of this Agreement, the Company shall cause 6,000 non-tax-
   qualified stock options (exercisable for shares of the Company's common
   stock) to be granted to Executive.  The 6,000 stock options provided for
   in this Section 1.4(c) shall be granted by the personnel committee of the
   Company under the terms of the Company's 1993 Stock Option and Incentive
   Plan and shall vest ratably over a five year period beginning from the
   date of their grant.

   1.5  Covenant Not to Compete.

        Executive acknowledges that the Company and the Bank would be
   substantially damaged by an association of Executive with a depository
   institution that competes for customers with the Company and the Bank. 
   Without the consent of the Company, Executive shall not at any time during
   the term of this Agreement or Executive's employment by the Bank, and for
   a period of one  year thereafter (regardless of the reason for
   termination), (i) on behalf of himself or as agent of any other person
   solicit any person who was a customer of the Company or the Bank or any of
   their subsidiaries during the two year period prior to the termination of
   this Agreement or Executive's employment hereunder for the purpose of
   offering the same products or rendering the same services to such customer
   as were provided or proposed to be provided by the Company or the Bank or
   any of their subsidiaries to such customer as of the time of termination
   of Executive's employment, or (ii) actively induce or solicit any
   employees of the Company or the Bank to leave such employ.  For purposes
   of this Section 1.5, "person" shall include any individual, corporation,
   partnership, trust, firm, proprietorship, venture or other entity of any
   nature whatsoever.

                                   ARTICLE II
                            TERMINATION OF EMPLOYMENT

   2.1  Voluntary Termination of Employment by Executive.

        Executive may terminate his employment hereunder at any time for any
   reason upon giving the Bank written notice, at least ninety (90) days
   prior to termination of employment.  Upon such termination, Executive
   shall be entitled to receive Executive's theretofore unpaid base salary in
   effect at the date such written notice is given for the period of
   employment up to the date of termination, and  Executive and his spouse
   and dependents will be entitled to further medical coverage, at his and/or
   their expense, to the extent required by COBRA.

   2.2  Termination of Employment for Death.

        If Executive's employment is terminated by reason of Executive's
   death, then Executive's personal representative shall be entitled to
   receive Executive's theretofore unpaid base salary for the period of
   employment up to the date of death.  Executive's spouse and dependent
   children shall continue to be entitled, at the expense of the Bank
   (subject to then existing co-payment features applicable under the Bank's
   medical insurance plan) if it is an insured plan, to further medical
   coverage to the extent permitted by COBRA; provided that, if the Bank's
   plan is not insured, the Bank will pay to Executive's spouse an additional
   monthly death benefit during the applicable COBRA period, based upon COBRA
   rates in effect at the time of Executive's death, in an amount equal to
   the COBRA rate plus taxes due on such cash payment; provided further that
   this benefit shall cease if the spouse and dependents cease to be eligible
   for COBRA coverage.

   2.3  Termination of Employment for Disability.

        If Executive becomes Totally and Permanently Disabled (as defined
   below) during the term of this Agreement, the Bank may terminate
   Executive's employment and this Agreement, except Section 1.5 and Article
   IV hereof, by giving Executive written notice of such termination not less
   than 5 days before the effective date thereof.  If Executive's employment
   and this Agreement are terminated pursuant to this Section 2.3, the Bank
   shall pay to Executive his theretofore unpaid base salary for the period
   of employment up to the date of termination, and the Company and the Bank
   shall have no further obligations to Executive under this Agreement,
   except for any COBRA obligations.  The Executive is Totally and
   Permanently Disabled for purposes of this Section 2.3 if he is disabled or
   incapacitated to the extent that he is unable to perform the duties of
   Vice President - Retail Lending and Secretary of the Company or the Bank
   for more than three (3) consecutive months, and such disability or
   incapacity (i) is expected to continue for more than three (3) additional
   months as certified by a medical doctor of the Company's choosing which is
   not contradicted by a doctor of the Executive's choosing or (ii) shall
   have in fact continued for more than three (3) additional months.

   2.4  Termination of Employment by the Company for Just Cause.

        The Bank may terminate Executive's employment hereunder for Just
   Cause (as such term is defined below), in which case the Executive shall
   be entitled to receive Executive's theretofore unpaid base salary for the
   period of employment up to the date of termination, but shall not be
   entitled to any compensation or employment benefits pursuant to this
   Agreement for any period after the date of termination, or the
   continuation of any benefits except as may be required by law, including,
   at his own expense, COBRA.

        "Just Cause" shall mean personal dishonesty, incompetence, willful
   misconduct or breach of a fiduciary duty involving personal profit in the
   performance of his duties under this Agreement, intentional failure to
   perform stated duties (provided that such nonperformance has continued for
   10 days after the Bank has given written notice of such nonperformance to
   the Executive and its intention to terminate Executive's employment
   hereunder because of such nonperformance), willful violation of any law,
   rule or regulation (other than a law, rule or regulation relating to a
   traffic violation or similar offense), final cease-and-desist order,
   termination under the provisions of Section 2.7(b) and (c) or material
   breach of any provision of this Agreement.  

   2.5  Termination of Employment by the Bank Without Cause.

        The Bank may terminate Executive's employment hereunder without
   cause, in which case the Executive shall receive (a) his base salary under
   Section 1.3 hereof through the then remaining term of employment under
   Section 1.1, (b) his theretofore unpaid base salary for the period of
   employment up to the date of termination, (c) medical, dental and life
   insurance through the then remaining term of employment under Section 1.1
   consistent with the terms and conditions set forth in Section 1.4, to the
   extent the same can be provided under the insurance arrangements of the
   Bank in effect at the time of termination, (d) any other benefits to which
   Executive is entitled by law or the specific terms of the Bank's policies
   in effect at the time of termination of employment and (e) an amount equal
   to the product of  the Bank's annual aggregate contribution, for the
   benefit of the Executive in the fiscal year preceding termination, to all
   qualified retirement plans in which the Executive participated multiplied
   by the number of years in the initial term of employment under Section
   1.1.  The benefit in (e) under this Section 2.5 shall be in addition to
   any benefit payable from any qualified or non-qualified plans or programs
   maintained by the Company or the Bank at the time of termination.  If the
   Bank's medical and dental plans are not insured, the medical and dental
   benefit in (c) shall be accomplished by the Bank paying to Executive an
   additional cash amount equal to the COBRA premium for such coverage, plus
   taxes on such amount, so that Executive may purchase the coverage on an
   after-tax basis.

   2.6  Termination of Employment Due to Change in Control.

        (a)    If, at any time after the date hereof, a "Change in Control"
   (as hereinafter defined) occurs and within eighteen (18) months thereafter
   Executive's appointment as Vice President - Retail Lending and Secretary
   of the Company or his employment as Vice President - Retail Lending and
   Secretary of the Bank is involuntarily terminated (other than for Just
   Cause pursuant to Section 2.4) then the Executive shall be entitled to the
   benefits provided below.

               (i)     The Company shall promptly pay, or cause the Bank to
   pay, to the Executive an amount equal to the product of 2.0 times the
   Executive's "base amount" as defined in Section 280G(b)(3) of the Code
   (such "base amount" to be derived from Executive's compensation paid by
   the Company and the Bank).

               (ii)     During the term of this Agreement set forth in
   paragraph 1.1 (including any renewal term), the Executive, his dependents,
   beneficiaries and estate shall continue to be covered under all employee
   benefit plans of the Company and the Bank, including without limitation
   the Company's and the Bank's pension and retirement plans, life insurance
   and health insurance as if the Executive was still employed by the Bank
   during such period under this Agreement; provided that coverage under the
   medical and dental plans of the Company and the Bank shall be handled as
   set forth in Section 2.5 above.

               (iii)   If and to the extent that benefits or services credit
   for benefits under Section 2.6(a)(ii) above shall not be payable or
   provided under any such plans to the Executive, his dependents,
   beneficiaries and estate, by reason of his no longer being an employee of
   the Bank as a result of termination of employment, the Company shall
   itself, or shall cause the Bank to, pay or provide for payment of such
   benefits and service credit for benefits to the Executive, his dependents,
   beneficiaries and estate.  Any such payment relating to retirement shall
   commence on a date selected by the Executive which must be a date on which
   payments under the Company or Bank's qualified pension plan or successor
   plan may commence.

        (b)    (i)     Anything in this Agreement to the contrary
   notwithstanding, it is the intention of the Company, the Bank and the
   Executive that no portion of any payment under this Agreement, or payments
   to or for the benefit of the Executive under any other agreement or plan,
   be deemed an "Excess Parachute Payment" as defined in Section 280G of the
   Code, or its successors.  It is agreed that the present value of any
   payment to or for the benefit of the Executive in the nature of
   compensation, receipt of which is contingent on the occurrence of a Change
   in Control, and to which Section 280G of the Code applies (in the
   aggregate "Total Payments") shall not exceed an amount equal to one dollar
   less than the maximum amount that the Company and the Bank may pay without
   loss of deduction under Section 280(G)(a) of the Code.  Present value for
   purposes of this Agreement shall be calculated in accordance with Section
   280G(d)(4) of the Code.  Within sixty days (60) following the earlier of
   (1) the giving of notice of termination of employment or (2) the giving of
   notice by the Company to the Executive of its belief that there is a
   payment or benefit due the Executive, the Company, at the Company's
   expense, shall obtain the opinion of the Company's public accounting firm
   (the "Accounting Firm"), which opinion need not be unqualified, which sets
   forth: (a) the amount of the Base Period Income of the Executive (as
   defined in Code Section 280G), (b) the present value of Total Payments and
   (c) the amount and present value of any Excess Parachute Payments.  In the
   event that such opinion determines that there would be an Excess Parachute
   Payment, the payment hereunder shall be modified, reduced or eliminated as
   specified by the Executive in writing delivered to the Company within
   thirty (30) days of his receipt of such opinion or, if the Executive fails
   to so notify the Company, then as the Company shall reasonably determine,
   so that under the bases of calculation set forth in such opinion there
   will be no Excess Parachute Payment.  In the event that the provisions of
   Sections 280G and 4999 of the Code are repealed without succession, this
   Section shall be of no further force or effect.

               (ii)    In the event that the Accounting Firm is serving as
   accountant or auditor for the individual, entity or group effecting the
   Change in Control, the Executive shall appoint another nationally
   recognized public accounting firm to make the determinations required
   hereunder (which accounting firm shall then be referred to as the
   Accounting Firm under Section 2.6(b)).  All fees and expenses of the
   Accounting Firm shall be borne solely by the Company.  Any determination
   by the Accounting Firm shall be binding upon the Company and the
   Executive.

        (c)    For purposes of Section 2.6 of this Agreement, a "Change in
   Control" shall be deemed to have occurred if:

               (i)     a third person, including a "group" as defined in
   Section 13(d)(3) of the Securities Exchange Act of 1934 (as in effect on
   the date hereof), becomes the beneficial owner of shares of the Company
   having 20% or more of the total number of votes that may be cast for the
   election of directors of the Company, including for this purpose any
   shares beneficially owned by such third person or group as of the date
   hereof; or

               (ii)    as the result of, or in connection with, any cash
   tender or exchange offer, merger or other business combination, sale of
   assets or contested election, or any combination of the foregoing
   transactions (a "Transaction"), the persons who were directors of the
   Company before the Transaction shall cease to constitute a majority of the
   Board of Directors of the Company or any successor to the Company. (In the
   event of any reorganization involving the Company in a transaction
   initiated by the Company in which the shareholders of the Company
   immediately prior to such reorganization become the shareholders of a
   successor or ultimate parent company of the Company resulting from such
   reorganization and the persons who were directors of the Company
   immediately prior to such reorganization constitute a majority of the
   Board of Directors of such successor or ultimate parent, no "Change in
   Control" shall be deemed to have taken place solely by reason of such
   reorganization, notwithstanding the fact that the Company may have become
   the wholly-owned subsidiary of another Company in such reorganization and
   the Board of Directors thereof may have been reconstituted, and thereafter
   the term "Company" for purposes of this paragraph shall refer to such
   successor or ultimate parent company.); or

               (iii)   a third person, including a "group" as defined in
   Section 13(d)(3) of the Securities Exchange Act of 1934 (as in effect on
   the date hereof), acquires control, as defined in 12 C.F.R. Section 
   574.4, or any successor regulation, of the Company which would require the
   filing of an application for acquisition of control or notice of change in
   control in a manner set forth in 12 C.F.R. Section  574.3, or any
   successor regulation; or

               (iv)    The terms "termination" or  "involuntarily terminated"
   in this Agreement shall refer to the termination of the employment of
   Executive by the Bank without his express written consent.  In addition,
   for purposes of this Agreement, a material diminution  or interference
   with the Executive's duties, responsibilities and benefits as Vice
   President - Retail Lending and Secretary of the Company or the Bank shall
   be deemed and shall constitute an involuntary termination of employment to
   the same extent as express notice of such involuntary termination.  By way
   of example and not by way of limitation, any of the following actions, if
   unreasonable or materially adverse to the Executive shall constitute such
   diminution or interference unless consented to in writing by the
   Executive: (1) a change in the principal work place of the Executive to a
   location outside a twenty-five mile radius from the Company's headquarters
   at 420 South Koeller Street, Oshkosh, Wisconsin; (2) a material reduction
   in the secretarial or other administrative support of the Executive; (3) a
   material demotion of the Executive, a material reduction in the number or
   seniority of other Company or Bank personnel reporting to the Executive,
   or a reduction in the frequency with which, or in the nature of the
   matters with respect to which, such personnel are to report to the
   Executive, other than as part of a Company-wide or Bank-wide reduction in
   staff; and (4) a reduction or adverse change in the salary,  perquisites,
   benefits, contingent benefits or vacation time which had theretofore been
   provided to the Executive, other than as part of an overall program
   applied uniformly and with equitable effect to all executive officers of
   the Company or the Bank.

   2.7  Termination or Suspension of Employment as Required by Law.

        Notwithstanding anything in this Agreement to the contrary, the
   following provisions shall limit the obligation of the Bank to continue
   employing Executive, but only to the extent required by the applicable
   regulations of the OTS (12 C.F.R. Section  563.39), or similar succeeding
   regulations:

        (a)    If the Executive is suspended and/or temporarily prohibited
   from participating in the conduct of the Bank's affairs by a notice served
   under Section 8(e)(3) or (g)(1) of the Federal Deposit Insurance Act (12
   U.S.C.  Section  1818(e)(3) and (g)(1)) the Bank's obligations under this
   Agreement shall be suspended as of the date of service of notice, unless
   stayed by appropriate proceedings.  If the charges in the notice are
   dismissed, the Bank may in its discretion (i) pay the Executive all or
   part of the compensation withheld while its contract obligations hereunder
   were suspended and (ii) reinstate (in whole or in part) any of its
   obligations which were suspended.

        (b)    If the Executive is removed and/or permanently prohibited from
   participating in the conduct of the Bank's affairs by an order issued
   under Section 8(e)(4) or (g)(1) of the Federal Deposit Insurance Act (12
   U.S.C. Section  1818(e)(4) or (g)(1)) all obligations of the Bank under
   this Agreement shall terminate as of the effective date of the order.

        (c)    If the Bank is in default (as defined in Section 3(x)(1) of
   the Federal Deposit Insurance Act), the obligation to Executive hereunder
   shall terminate as of the date of default.

        (d)    All obligations under this Agreement may be terminated:  (i)
   by the Director of the Office of Thrift Supervision (the "Director") or
   his or her designee at the time the Federal Deposit Insurance Company
   enters into an agreement to provide assistance to or on behalf of the Bank
   under the authority contained in Section 13(c) of the Federal Deposit
   Insurance Act and (ii) by the Director, or his or her designee at the time
   the Director or such designee approves a supervisory merger to resolve
   problems related to operation of the Bank or when the Bank is determined
   by the Director to be in an unsafe or unsound condition.

        (e)    Termination pursuant to subparagraph (d) of this Section 2.7
   shall be treated as a termination by the Bank without cause entitling
   Executive to benefits payable under Section 2.5.  Termination pursuant to
   subparagraph (a), (b) or (c) shall be treated as a termination for Just
   Cause under Section 2.4.  Termination under this Section 2.7 shall not
   affect other rights hereunder which are vested at the time of termination.

   2.8  Limitation on Termination or Disability Pay.

        Any payments made to the Executive pursuant to this Agreement or
   otherwise are subject to and conditioned upon their compliance with 12
   U.S.C. Section  1828(k) and any regulations promulgated thereunder.

                                   ARTICLE III
                             LEGAL FEES AND EXPENSES

        The Company shall pay, or shall cause the Bank to pay, all legal fees
   and expenses which the Executive may incur as a result of the Company or
   the Bank contesting the validity or enforceability of this Agreement,
   provided that the Executive is the prevailing party in such contest or
   that any dispute may otherwise be settled in favor of the Executive.  The
   Executive shall be entitled to receive interest thereon for the period of
   any delay in payment from the date such payment was due at the rate
   determined by adding two hundred basis points to the six-month Treasury
   Bill rate.

                                   ARTICLE IV
                                 CONFIDENTIALITY

        Executive acknowledges that he now has, and in the course of his
   employment will have, access to important and confidential information
   regarding the business and services of the Company, the Bank and their
   subsidiaries, as well as similar information regarding OSB Financial and
   its subsidiaries, and that the disclosure to, or the use of such
   information by, and business in competition with the Company, the Bank or
   their subsidiaries shall result in substantial and undeterminable harm to
   the Company, the Bank and their subsidiaries.  In order to protect the
   Company, the Bank and their subsidiaries against such harm and from unfair
   competition, Executive agrees with the Company and the Bank that while
   employed by the Bank and at any time thereafter, Executive will not
   disclose, communicate or divulge to anyone, or use in any manner adverse
   to the Company, the Bank or their subsidiaries any information concerning
   customers, methods of business, financial information or other
   confidential information of the Company, the Bank, their subsidiaries or
   similar information regarding OSB Financial and its subsidiaries, except
   for information as is in the public domain or ascertainable through common
   sources of public information (otherwise than as a result of any breach of
   this covenant by Executive).

                                    ARTICLE V
                               GENERAL PROVISIONS

   5.1  Inquiries Regarding Proposed Activities.

        In the event Executive shall inquire in writing of the Company
   whether any proposed action on the part of Executive would be considered
   by the Company or the Bank to be prohibited by or in breach of the terms
   of this Agreement, the Company shall have 30 days after receipt of such
   notice to express in writing to Executive its position with respect
   thereof and in the event such writing shall not be given to Executive,
   such proposed action, as set forth in the writing of the Executive, shall
   not be deemed to be a violation of or breach of this Agreement.

   5.2  No Duty of Mitigation.

        The Executive shall not be required to mitigate the amount of any
   payment or benefit provided for in this Agreement by seeking other
   employment or otherwise, nor shall the amount of any payment or benefit
   provided for in this Agreement be reduced by any compensation earned by
   the Executive as the result of employment by another employer, by
   retirement benefits after the date of termination of this Agreement or
   otherwise.
     
   5.3  Successors.

   other business entity that is directly or indirectly controlled by the
   Company or the Bank.  This Agreement may not be assigned by the Company or
   the Bank except in connection with a merger involving the Company or the
   Bank or a sale of substantially all of the assets of the Company or the
   Bank, and the respective obligations of the Company and the Bank provided
   for in this Agreement shall be the binding legal obligations of any
   successor to the Company or the Bank by purchase, merger, consolidation,
   or otherwise.  This Agreement may not be assigned by the Executive during
   his life, and upon his death will be binding upon and inure to the benefit
   of his heirs, legatees and the legal representatives of his estate.

                              EMPLOYMENT AGREEMENT

   Bank survive the merger (collectively, the "Merger");

               WHEREAS, prior to the Merger, OSB Financial employed the
   Executive as President and Chief Executive Officer of OSB Financial under
   the terms of an employment agreement, dated July 1, 1995;

               NOW, THEREFORE, in consideration of the foregoing and of the
   respective covenants and agreements of the parties herein contained, it is
   agreed as follows:

                                    ARTICLE I
                                   EMPLOYMENT

   (a)1 Term of Employment.

        The Bank hereby employs Executive for an initial period of three (3)
   years commencing on _______, 1997 (the "Commencement Date") and
   terminating on ________, 2000 (the "Initial Termination Date"), subject to
   earlier termination as provided in Article II hereof.  The Board of
   Directors of the Bank shall review and may extend the term of this
   Agreement for a period of one (1) additional year beginning on the Initial
   Termination Date and in each subsequent year thereafter for a period of
   one (1) additional year.  Any extensions of the term of this Agreement
   shall be made by giving Executive written notice of such extension at
   least 90 days prior to the Initial Termination Date or the expiration of
   any renewal period.  Reference herein to the term of this Agreement shall
   refer to both the initial term and such extended terms.

   1.2  Duties of Executive.

        The Bank hereby employs Executive, and Executive hereby accepts
   employment with the Bank, upon the terms and conditions hereinafter set
   forth for the term of this Agreement.  Executive is employed by the Bank
   to perform the duties of President and Chief Executive Officer of the
   Bank, and the Company shall cause the Bank to appoint Executive to such
   position.   As part of Executive's employment by the Bank hereunder,
   Executive shall also serve as, and the Company hereby appoints Executive
   during the term of his employment by the Bank hereunder to serve as,
   President and Chief Executive officer of the Company.  The services to be
   performed by the Executive shall include those normally performed by the
   President and Chief Executive Officer of similar banking organizations and
   as directed by the Board of Directors of the Company and the Bank,
   respectively, which are not inconsistent with the foregoing.  Executive
   agrees to devote his full business time to the rendition of such services,
   subject to absences for customary vacations and for temporary illnesses. 
   The Company and the Bank each agree that during the term of this Agreement
   it will not reduce the Executive's current job title, status or
   responsibilities without the Executive's consent.  Furthermore, Executive
   shall not be required, without his express written consent, to be based
   anywhere other than within the Oshkosh-Neenah/Menasha-Appleton
   metropolitan area, except for reasonable business travel in connection
   with the business of the Company and the Bank.  During the term of this
   Agreement, Executive shall also serve as a director of the Company
   (subject to being elected by shareholders) and the Bank without any
   additional compensation. 

   1.3  Compensation.

        The Bank agrees to compensate, and the Company agrees to cause the
   Bank to compensate, the Executive for his services hereunder during the
   term of this Agreement by payment of a salary at the annual rate of
   $150,000 in such monthly, semi-monthly or other payments as are from time
   to time applicable to other executive officers of the Bank.  The
   Executive's salary may be increased from time to time during the term of
   this Agreement in the sole discretion of the Board of Directors of the
   Bank, but Executive's salary shall not be reduced below the level then in
   effect.  In addition, Executive shall be entitled to participate in
   incentive compensation plans as may from time to time be established by
   the Company or the Bank on an equivalent basis as other executive officers
   of the Company or the Bank (but recognizing differences in
   responsibilities among executive officers).

   1.4  Benefits.

        (a)    Executive shall be provided the following additional benefits,
   (i) participation in any pension, profit-sharing, deferred compensation or
   other retirement plan, (ii) medical, dental and life insurance coverage
   consistent with coverages provided to other executive officers of the Bank
   (which initially will include a 30% co-pay by the Executive), (iii) the
   use of an automobile and membership or appropriate affiliation with a
   service club and a recreational club, (iv) reimbursement of business
   expenses reasonably incurred in connection with his employment and
   expenses incurred by his spouse when accompanying Executive, (v) paid
   vacations and sick leave in accordance with prevailing policies of the
   Bank, provided that allowed vacations shall in no event be less than four
   weeks per annum, and (vi) such other benefits as are provided to other
   executive officers of the Bank; provided that amounts allocated to
   Executive's personal use under clause (iii) above and additional charges
   for Executive's spouse pursuant to clause (iv) above shall be treated as
   taxable income to Executive in accordance with applicable Bank policies.

        (b)     If Executive shall become temporarily disabled or
   incapacitated to the extent that he is unable to perform the duties of
   President and Chief Executive Officer of the Company or the Bank for three
   (3) consecutive months, he shall nevertheless be entitled to receive 100
   percent of his compensation under Section 1.3 of this Agreement for the
   period of his disability up to three (3) months, less any amount paid to
   the Executive under any other disability program maintained by the Company
   or the Bank or disability insurance policy maintained for the benefit of
   Executive by the Company or the Bank.  Upon returning to active full-time
   employment, Executive's full compensation as set forth in this Agreement
   shall be reinstated.  In the event that Executive returns to active
   employment on other than a full-time basis with the approval of the Board
   of Directors of the Bank, then his compensation (as set forth in Section
   1.3 of this Agreement) shall be reduced proportionately based upon the
   fraction of full-time employment devoted by Executive to his employment
   and responsibilities at the Bank and the Company.  But, if he is again
   unable to perform the duties of President and Chief Executive Officer of
   the Company and the Bank hereunder due to disability or incapacity, he
   must have been engaged in active full-time employment for at least twelve
   (12) consecutive months immediately prior to such later absence or
   inability in order to qualify for the full or partial continuance of his
   salary under this Section (b). 

        (c)    It is the intention of the Company that, within 30 days after
   the date of this Agreement, the Company shall cause 20,000 non-tax-
   qualified stock options (exercisable for shares of the Company's common
   stock) to be granted to Executive.  The 20,000 stock options provided for
   in this Section 1.4(c) shall be granted by the personnel committee of the
   Company under the terms of the Company's 1993 Stock Option and Incentive
   Plan and shall vest ratably over a five year period beginning from the
   date of their grant.

   1.5  Covenant Not to Compete.

        Executive acknowledges that the Company and the Bank would be
   substantially damaged by an association of Executive with a depository
   institution that competes for customers with the Company and the Bank. 
   Without the consent of the Company, Executive shall not at any time during
   the term of this Agreement or Executive's employment by the Bank, and for
   a period of one year thereafter (regardless of the reason for
   termination), (i) on behalf of himself or as agent of any other person
   solicit any person who was a customer of the Company or the Bank or any of
   their subsidiaries during the two year period prior to the termination of
   this Agreement or Executive's employment hereunder for the purpose of
   offering the same products or rendering the same services to such customer
   as were provided or proposed to be provided by the Company or the Bank or
   any of their subsidiaries to such customer as of the time of termination
   of Executive's employment, (ii) directly or indirectly, on Executive's
   behalf or in the service or on the behalf of others, render or be retained
   to render similar services as described in Section 1.2 hereof, whether as
   an officer, partner, trustee, consultant, or employee for any depository
   institution, which has a banking office located within 10 miles of any
   office of the Bank or any banking office of the Company in existence as of
   the Commencement Date or the beginning of any renewal period as provided
   in Section 1.1 hereof, provided, however, that Executive shall not be
   deemed to have breached this undertaking if (a) he renders services
   otherwise prohibited by this paragraph (ii) for a depository institution
   which has its home office located outside of the Wisconsin counties of
   Winnebago and Outagamie and he renders such services from a full-service
   banking office of such depository institution which is located outside
   these same Wisconsin counties, or (b) his sole relationship with any other
   such entity consists of his holding, directly or indirectly, an equity
   interest in such entity not greater than three percent (3%) of such
   entity's outstanding equity interest, or (iii) actively induce or solicit
   any employees of the Company or the Bank to leave such employ.  For
   purposes of this Section 1.5, "person" shall include any individual,
   corporation, partnership, trust, firm, proprietorship, venture or other
   entity of any nature whatsoever.

                                   ARTICLE II
                            TERMINATION OF EMPLOYMENT

   2.1  Voluntary Termination of Employment by Executive.

        Executive may terminate his employment hereunder at any time for any
   reason upon giving the Bank written notice, at least ninety (90) days
   prior to termination of employment.  Upon such termination, Executive
   shall be entitled to receive Executive's theretofore unpaid base salary in
   effect at the date such written notice is given for the period of
   employment up to the date of termination, and  Executive and his spouse
   and dependents will be entitled to further medical coverage, at his and/or
   their expense, to the extent required by COBRA.

   2.2  Termination of Employment for Death.

        If Executive's employment is terminated by reason of Executive's
   death, then Executive's personal representative shall be entitled to
   receive Executive's theretofore unpaid base salary for the period of
   employment up to the date of death.  Executive's spouse and dependent
   children shall continue to be entitled, at the expense of the Bank
   (subject to then existing co-payment features applicable under the Bank's
   medical insurance plan) if it is an insured plan, to further medical
   coverage to the extent permitted by COBRA; provided that, if the Bank's
   plan is not insured, the Bank will pay to Executive's spouse an additional
   monthly death benefit during the applicable COBRA period, based upon COBRA
   rates in effect at the time of Executive's death, in an amount equal to
   the COBRA rate plus taxes due on such cash payment; provided further that
   this benefit shall cease if the spouse and dependents cease to be eligible
   for COBRA coverage.

   2.3  Termination of Employment for Disability.

        If Executive becomes Totally and Permanently Disabled (as defined
   below) during the term of this Agreement, the Bank may terminate
   Executive's employment and this Agreement, except Section 1.5 and Article
   IV hereof, by giving Executive written notice of such termination not less
   than 5 days before the effective date thereof.  If Executive's employment
   and this Agreement are terminated pursuant to this Section 2.3, the Bank
   shall pay to Executive his theretofore unpaid base salary for the period
   of employment up to the date of termination, and the Company and the Bank
   shall have no further obligations to Executive under this Agreement,
   except for any COBRA obligations.  The Executive is Totally and
   Permanently Disabled for purposes of this Section 2.3 if he is disabled or
   incapacitated to the extent that he is unable to perform the duties of
   President and Chief Executive Officer of the Company or the Bank for more
   than three (3) consecutive months, and such disability or incapacity (i)
   is expected to continue for more than three (3) additional months as
   certified by a medical doctor of the Company's choosing which is not
   contradicted by a doctor of the Executive's choosing or (ii) shall have in
   fact continued for more than three (3) additional months.

   2.4  Termination of Employment by the Company for Just Cause.

        The Bank may terminate Executive's employment hereunder for Just
   Cause (as such term is defined below), in which case the Executive shall
   be entitled to receive Executive's theretofore unpaid base salary for the
   period of employment up to the date of termination, but shall not be
   entitled to any compensation or employment benefits pursuant to this
   Agreement for any period after the date of termination, or the
   continuation of any benefits except as may be required by law, including,
   at his own expense, COBRA.

        "Just Cause" shall mean personal dishonesty, incompetence, willful
   misconduct or breach of a fiduciary duty involving personal profit in the
   performance of his duties under this Agreement, intentional failure to
   perform stated duties (provided that such nonperformance has continued for
   10 days after the Bank has given written notice of such nonperformance to
   the Executive and its intention to terminate Executive's employment
   hereunder because of such nonperformance), willful violation of any law,
   rule or regulation (other than a law, rule or regulation relating to a
   traffic violation or similar offense), final cease-and-desist order,
   termination under the provisions of Section 2.7(b) and (c) or material
   breach of any provision of this Agreement.  

   2.5  Termination of Employment by the Bank Without Cause.

        The Bank may terminate Executive's employment hereunder without
   cause, in which case the Executive shall receive (a) his base salary under
   Section 1.3 hereof through the then remaining term of employment under
   Section 1.1, (b) his theretofore unpaid base salary for the period of
   employment up to the date of termination, (c) medical, dental and life
   insurance through the then remaining term of employment under Section 1.1
   consistent with the terms and conditions set forth in Section 1.4, to the
   extent the same can be provided under the insurance arrangements of the
   Bank in effect at the time of termination, (d) any other benefits to which
   Executive is entitled by law or the specific terms of the Bank's policies
   in effect at the time of termination of employment and (e) an amount equal
   to the product of  the Bank's annual aggregate contribution, for the
   benefit of the Executive in the fiscal year preceding termination, to all
   qualified retirement plans in which the Executive participated multiplied
   by the number of years in the initial term of employment under Section
   1.1.  The benefit in (e) under this Section 2.5 shall be in addition to
   any benefit payable from any qualified or non-qualified plans or programs
   maintained by the Company or the Bank at the time of termination.  If the
   Bank's medical and dental plans are not insured, the medical and dental
   benefit in (c) shall be accomplished by the Bank paying to Executive an
   additional cash amount equal to the COBRA premium for such coverage, plus
   taxes on such amount, so that Executive may purchase the coverage on an
   after-tax basis.

   2.6  Termination of Employment Due to Change in Control.

        (a)    If, at any time after the date hereof, a "Change in Control"
   (as hereinafter defined) occurs and within eighteen (18) months thereafter
   Executive's appointment as President or as Chief Executive Officer of the
   Company or his employment as President or as Chief Executive Officer of
   the Bank is involuntarily terminated (other than for Just Cause pursuant
   to Section 2.4) then the Executive shall be entitled to the benefits
   provided below.

               (i)     The Company shall promptly pay, or cause the Bank to
   pay, to the Executive an amount equal to the product of 2.00 times the
   Executive's "base amount" as defined in Section 280G(b)(3) of the Code
   (such "base amount" to be derived from Executive's compensation paid by
   the Company and the Bank).

               (ii)     During the term of this Agreement set forth in
   paragraph 1.1 (including any renewal term), the Executive, his dependents,
   beneficiaries and estate shall continue to be covered under all employee
   benefit plans of the Company and the Bank, including without limitation
   the Company's and the Bank's pension and retirement plans, life insurance
   and health insurance as if the Executive was still employed by the Bank
   during such period under this Agreement; provided that coverage under the
   medical and dental plans of the Company and the Bank shall be handled as
   set forth in Section 2.5 above.

               (iii)   If and to the extent that benefits or services credit
   for benefits under Section 2.6(a)(ii) above shall not be payable or
   provided under any such plans to the Executive, his dependents,
   beneficiaries and estate, by reason of his no longer being an employee of
   the Bank as a result of termination of employment, the Company shall
   itself, or shall cause the Bank to, pay or provide for payment of such
   benefits and service credit for benefits to the Executive, his dependents,
   beneficiaries and estate.  Any such payment relating to retirement shall
   commence on a date selected by the Executive which must be a date on which
   payments under the Company or Bank's qualified pension plan or successor
   plan may commence.

        (b)    (i)     Anything in this Agreement to the contrary
   notwithstanding, it is the intention of the Company, the Bank and the
   Executive that no portion of any payment under this Agreement, or payments
   to or for the benefit of the Executive under any other agreement or plan,
   be deemed an "Excess Parachute Payment" as defined in Section 280G of the
   Code, or its successors.  It is agreed that the present value of any
   payment to or for the benefit of the Executive in the nature of
   compensation, receipt of which is contingent on the occurrence of a Change
   in Control, and to which Section 280G of the Code applies (in the
   aggregate "Total Payments") shall not exceed an amount equal to one dollar
   less than the maximum amount that the Company and the Bank may pay without
   loss of deduction under Section 280(G)(a) of the Code.  Present value for
   purposes of this Agreement shall be calculated in accordance with Section
   280G(d)(4) of the Code.  Within sixty days (60) following the earlier of
   (1) the giving of notice of termination of employment or (2) the giving of
   notice by the Company to the Executive of its belief that there is a
   payment or benefit due the Executive, the Company, at the Company's
   expense, shall obtain the opinion of the Company's public accounting firm
   (the "Accounting Firm"), which opinion need not be unqualified, which sets
   forth: (a) the amount of the Base Period Income of the Executive (as
   defined in Code Section 280G), (b) the present value of Total Payments and
   (c) the amount and present value of any Excess Parachute Payments.  In the
   event that such opinion determines that there would be an Excess Parachute
   Payment, the payment hereunder shall be modified, reduced or eliminated as
   specified by the Executive in writing delivered to the Company within
   thirty (30) days of his receipt of such opinion or, if the Executive fails
   to so notify the Company, then as the Company shall reasonably determine,
   so that under the bases of calculation set forth in such opinion there
   will be no Excess Parachute Payment.  In the event that the provisions of
   Sections 280G and 4999 of the Code are repealed without succession, this
   Section shall be of no further force or effect.

               (ii)    In the event that the Accounting Firm is serving as
   accountant or auditor for the individual, entity or group effecting the
   Change in Control, the Executive shall appoint another nationally
   recognized public accounting firm to make the determinations required
   hereunder (which accounting firm shall then be referred to as the
   Accounting Firm under Section 2.6(b)).  All fees and expenses of the
   Accounting Firm shall be borne solely by the Company.  Any determination
   by the Accounting Firm shall be binding upon the Company and the
   Executive.

        (c)    For purposes of Section 2.6 of this Agreement, a "Change in
   Control" shall be deemed to have occurred if:

               (i)     a third person, including a "group" as defined in
   Section 13(d)(3) of the Securities Exchange Act of 1934 (as in effect on
   the date hereof), becomes the beneficial owner of shares of the Company
   having 20% or more of the total number of votes that may be cast for the
   election of directors of the Company, including for this purpose any
   shares beneficially owned by such third person or group as of the date
   hereof; or

               (ii)    as the result of, or in connection with, any cash
   tender or exchange offer, merger or other business combination, sale of
   assets or contested election, or any combination of the foregoing
   transactions (a "Transaction"), the persons who were directors of the
   Company before the Transaction shall cease to constitute a majority of the
   Board of Directors of the Company or any successor to the Company. (In the
   event of any reorganization involving the Company in a transaction
   initiated by the Company in which the shareholders of the Company
   immediately prior to such reorganization become the shareholders of a
   successor or ultimate parent company of the Company resulting from such
   reorganization and the persons who were directors of the Company
   immediately prior to such reorganization constitute a majority of the
   Board of Directors of such successor or ultimate parent, no "Change in
   Control" shall be deemed to have taken place solely by reason of such
   reorganization, notwithstanding the fact that the Company may have become
   the wholly-owned subsidiary of another Company in such reorganization and
   the Board of Directors thereof may have been reconstituted, and thereafter
   the term "Company" for purposes of this paragraph shall refer to such
   successor or ultimate parent company.); or

               (iii)   a third person, including a "group" as defined in
   Section 13(d)(3) of the Securities Exchange Act of 1934 (as in effect on
   the date hereof), acquires control, as defined in 12 C.F.R. Section 
   574.4, or any successor regulation, of the Company which would require the
   filing of an application for acquisition of control or notice of change in
   control in a manner set forth in 12 C.F.R. Section  574.3, or any
   successor regulation; or

               (iv)    The terms "termination" or  "involuntarily terminated"
   in this Agreement shall refer to the termination of the employment of
   Executive by the Bank without his express written consent.  In addition,
   for purposes of this Agreement, a material diminution  or interference
   with the Executive's duties, responsibilities and benefits as President
   and Chief Executive Officer of the Company or the Bank shall be deemed and
   shall constitute an involuntary termination of employment to the same
   extent as express notice of such involuntary termination.  By way of
   example and not by way of limitation, any of the following actions, if
   unreasonable or materially adverse to the Executive shall constitute such
   diminution or interference unless consented to in writing by the
   Executive: (1) a change in the principal work place of the Executive to a
   location outside a twenty-five mile radius from the Company's headquarters
   at 420 South Koeller Street, Oshkosh, Wisconsin; (2) a material reduction
   in the secretarial or other administrative support of the Executive; (3) a
   material demotion of the Executive, a material reduction in the number or
   seniority of other Company or Bank personnel reporting to the Executive,
   or a reduction in the frequency with which, or in the nature of the
   matters with respect to which, such personnel are to report to the
   Executive, other than as part of a Company-wide or Bank-wide reduction in
   staff; and (4) a reduction or adverse change in the salary,  perquisites,
   benefits, contingent benefits or vacation time which had theretofore been
   provided to the Executive, other than as part of an overall program
   applied uniformly and with equitable effect to all executive officers of
   the Company or the Bank.

   2.7  Termination or Suspension of Employment as Required by Law.

        Notwithstanding anything in this Agreement to the contrary, the
   following provisions shall limit the obligation of the Bank to continue
   employing Executive, but only to the extent required by the applicable
   regulations of the OTS (12 C.F.R. Section  563.39), or similar succeeding
   regulations:

        (a)    If the Executive is suspended and/or temporarily prohibited

   U.S.C.  Section  1818(e)(3) and (g)(1)) the Bank's obligations under this
   Agreement shall be suspended as of the date of service of notice, unless
   stayed by appropriate proceedings.  If the charges in the notice are
   dismissed, the Bank may in its discretion (i) pay the Executive all or
   part of the compensation withheld while its contract obligations hereunder
   were suspended and (ii) reinstate (in whole or in part) any of its
   obligations which were suspended.

        (b)    If the Executive is removed and/or permanently prohibited from
   participating in the conduct of the Bank's affairs by an order issued
   under Section 8(e)(4) or (g)(1) of the Federal Deposit Insurance Act (12
   U.S.C. Section  1818(e)(4) or (g)(1)) all obligations of the Bank under

   under the authority contained in Section 13(c) of the Federal Deposit
   Insurance Act and (ii) by the Director, or his or her designee at the time
   the Director or such designee approves a supervisory merger to resolve
   problems related to operation of the Bank or when the Bank is determined
   by the Director to be in an unsafe or unsound condition.

        (e)    Termination pursuant to subparagraph (d) of this Section 2.7
   shall be treated as a termination by the Bank without cause entitling
   Executive to benefits payable under Section 2.5.  Termination pursuant to
   subparagraph (a), (b) or (c) shall be treated as a termination for Just
   Cause under Section 2.4.  Termination under this Section 2.7 shall not
   affect other rights hereunder which are vested at the time of termination.

   2.8  Limitation on Termination or Disability Pay.

   any delay in payment from the date such payment was due at the rate
   determined by adding two hundred basis points to the six-month Treasury
   Bill rate.

                                   ARTICLE IV

               WHEREAS, prior to the Merger, OSB Bank employed the Executive
   as Vice President - Retail Sales and Service;

               WHEREAS, consummation of the Merger contemplated by the Merger

               NOW, THEREFORE, in consideration of the foregoing and of the
   respective covenants and agreements of the parties herein contained, it is
   agreed as follows:

                                    ARTICLE I
                                   EMPLOYMENT

   1.1  Term of Employment.

        The Bank hereby employs Executive for an initial period of fifteen
   (15) months commencing on _______, 1997 (the "Commencement Date") and
   terminating on ________, 1998 (the "Initial Termination Date"), subject to

   any renewal period.  Reference herein to the term of this Agreement shall
   refer to both the initial term and such extended terms.

   1.2  Duties of Executive.

        The Bank hereby employs Executive, and Executive hereby accepts
   employment with the Bank, upon the terms and conditions hereinafter set
   forth for the term of this Agreement.  Executive is employed by the Bank
   to perform the duties of Vice President - Retail Sales and Service of the
   Bank, and the Company shall cause the Bank to appoint Executive to such
   position.  As part of Executive's employment by the Bank hereunder,
   Executive shall also serve as, and the Company hereby appoints Executive
   during the term of his employment by the Bank hereunder to serve as Vice
   President - Retail Sales and Service of the Company.  The services to be
   performed by the Executive shall include those normally performed by Vice
   President - Retail Sales and Service of similar banking organizations and
   as directed by the Board of Directors of the Company and the Bank,
   respectively, which are not inconsistent with the foregoing. Executive
   agrees to devote his full business time to the rendition of such services,
   subject to absences for customary vacations and for temporary illnesses. 
   The Company and the Bank each agree that during the term of this Agreement
   it will not reduce the Executive's current job title, status or
   responsibilities without the Executive's consent.  Furthermore, Executive
   shall not be required, without his express written consent, to be based
   anywhere other than within the Oshkosh-Neenah/Menasha-Appleton
   metropolitan area, except for reasonable business travel in connection
   with the business of the Company and the Bank.
       
   1.3  Compensation.

        The Bank agrees to compensate, and the Company agrees to cause the
   Bank to compensate, the Executive for his services hereunder during the
   term of this Agreement by payment of a salary at the annual rate of
   $70,000 in such monthly, semi-monthly or other payments as are from time
   to time applicable to other executive officers of the Bank.  The
   Executive's salary may be increased from time to time during the term of
   this Agreement in the sole discretion of the Board of Directors of the
   Bank, but Executive's salary shall not be reduced below the level then in
   effect.  In addition, Executive shall be entitled to participate in
   incentive compensation plans as may from time to time be established by
   the Company or the Bank on an equivalent basis as other executive officers
   of the Company or the Bank (but recognizing differences in
   responsibilities among executive officers).

   1.4  Benefits.

        (a)    Executive shall be provided the following additional benefits,
   (i) participation in any pension, profit-sharing, deferred compensation or
   other retirement plan, (ii) medical, dental and life insurance coverage
   consistent with coverages provided to other executive officers of the Bank
   (which initially will include a 30% co-pay by the Executive), (iii)
   membership or appropriate affiliation with a recreational club, (iv)
   reimbursement of business expenses reasonably incurred in connection with
   his employment and expenses incurred by his spouse when accompanying
   Executive, (v) paid vacations and sick leave in accordance with prevailing
   policies of the Bank, provided that allowed vacations shall in no event be
   less than four weeks per annum, and (vi) such other benefits as are
   provided to other executive officers of the Bank; provided that amounts
   allocated to Executive's personal use under clause (iii) above and
   additional charges for Executive's spouse pursuant to clause (iv) above
   shall be treated as taxable income to Executive in accordance with
   applicable Bank policies.

        (b)     If Executive shall become temporarily disabled or
   incapacitated to the extent that he is unable to perform the duties of
   Vice President - Retail Sales and Service of the Company or the Bank for
   three (3) consecutive months, he shall nevertheless be entitled to receive
   100 percent of his compensation under Section 1.3 of this Agreement for
   the period of his disability up to three (3) months, less any amount paid
   to the Executive under any other disability program maintained by the
   Company or the Bank or disability insurance policy maintained for the
   benefit of Executive by the Company or the Bank.  Upon returning to active
   full-time employment, Executive's full compensation as set forth in this
   Agreement shall be reinstated.  In the event that Executive returns to
   active employment on other than a full-time basis with the approval of the
   Board of Directors of the Bank, then his compensation (as set forth in
   Section 1.3 of this Agreement) shall be reduced proportionately based upon
   the fraction of full-time employment devoted by Executive to his
   employment and responsibilities at the Bank and the Company.  But, if he
   is again unable to perform the duties of Vice President - Retail Sales and
   Service of the Company and the Bank hereunder due to disability or
   incapacity, he must have been engaged in active full-time employment for
   at least twelve (12) consecutive months immediately prior to such later
   absence or inability in order to qualify for the full or partial
   continuance of his salary under this Section (b). 

        (c)    It is the intention of the Company that, within 30 days after
   the date of this Agreement, the Company shall cause 6,000 non-tax-
   qualified stock options (exercisable for shares of the Company's common
   stock) to be granted to Executive.  The 6,000 stock options provided for
   in this Section 1.4(c) shall be granted by the personnel committee of the
   Company under the terms of the Company's 1993 Stock Option and Incentive
   Plan and shall vest ratably over a five year period beginning from the
   date of their grant.

   1.5  Covenant Not to Compete.

        Executive acknowledges that the Company and the Bank would be
   substantially damaged by an association of Executive with a depository
   institution that competes for customers with the Company and the Bank. 
   Without the consent of the Company, Executive shall not at any time during
   the term of this Agreement or Executive's employment by the Bank, and for
   a period of one year thereafter (regardless of the reason for
   termination), (i) on behalf of himself or as agent of any other person
   solicit any person who was a customer of the Company or the Bank or any of
   their subsidiaries during the two year period prior to the termination of
   this Agreement or Executive's employment hereunder for the purpose of
   offering the same products or rendering the same services to such customer
   as were provided or proposed to be provided by the Company or the Bank or
   any of their subsidiaries to such customer as of the time of termination
   of Executive's employment, or (ii) actively induce or solicit any
   employees of the Company or the Bank to leave such employ.  For purposes
   of this Section 1.5, "person" shall include any individual, corporation,
   partnership, trust, firm, proprietorship, venture or other entity of any
   nature whatsoever.

                                   ARTICLE II

   2.1  Voluntary Termination of Employment by Executive.

        Executive may terminate his employment hereunder at any time for any
   reason upon giving the Bank written notice, at least ninety (90) days
   prior to termination of employment.  Upon such termination, Executive
   shall be entitled to receive Executive's theretofore unpaid base salary in
   effect at the date such written notice is given for the period of
   employment up to the date of termination, and  Executive and his spouse
   and dependents will be entitled to further medical coverage, at his and/or
   their expense, to the extent required by COBRA.

   2.2  Termination of Employment for Death.

        If Executive's employment is terminated by reason of Executive's
   death, then Executive's personal representative shall be entitled to
   receive Executive's theretofore unpaid base salary for the period of
   employment up to the date of death.  Executive's spouse and dependent
   children shall continue to be entitled, at the expense of the Bank
   (subject to then existing co-payment features applicable under the Bank's
   medical insurance plan) if it is an insured plan, to further medical
   coverage to the extent permitted by COBRA; provided that, if the Bank's
   plan is not insured, the Bank will pay to Executive's spouse an additional
   monthly death benefit during the applicable COBRA period, based upon COBRA
   rates in effect at the time of Executive's death, in an amount equal to
   the COBRA rate plus taxes due on such cash payment; provided further that
   this benefit shall cease if the spouse and dependents cease to be eligible
   for COBRA coverage.

   2.3  Termination of Employment for Disability.

        If Executive becomes Totally and Permanently Disabled (as defined
   below) during the term of this Agreement, the Bank may terminate
   Executive's employment and this Agreement, except Section 1.5 and Article
   IV hereof, by giving Executive written notice of such termination not less
   than 5 days before the effective date thereof.  If Executive's employment
   and this Agreement are terminated pursuant to this Section 2.3, the Bank
   shall pay to Executive his theretofore unpaid base salary for the period
   of employment up to the date of termination, and the Company and the Bank
   shall have no further obligations to Executive under this Agreement,
   except for any COBRA obligations.  The Executive is Totally and
   Permanently Disabled for purposes of this Section 2.3 if he is disabled or
   incapacitated to the extent that he is unable to perform the duties of
   Vice President - Retail Sales and Services of the Company and the Bank for
   more than three (3) consecutive months, and such disability or incapacity
   (i) is expected to continue for more than three (3) additional months as
   certified by a medical doctor of the Company's choosing which is not
   contradicted by a doctor of the Executive's choosing or (ii) shall have in
   fact continued for more than three (3) additional months.

   2.4  Termination of Employment by the Company for Just Cause.

        The Bank may terminate Executive's employment hereunder for Just
   Cause (as such term is defined below), in which case the Executive shall
   be entitled to receive Executive's theretofore unpaid base salary for the
   period of employment up to the date of termination, but shall not be
   entitled to any compensation or employment benefits pursuant to this
   Agreement for any period after the date of termination, or the
   continuation of any benefits except as may be required by law, including,
   at his own expense, COBRA.

        "Just Cause" shall mean personal dishonesty, incompetence, willful
   misconduct or breach of a fiduciary duty involving personal profit in the
   performance of his duties under this Agreement, intentional failure to
   perform stated duties (provided that such nonperformance has continued for
   10 days after the Bank has given written notice of such nonperformance to
   the Executive and its intention to terminate Executive's employment
   hereunder because of such nonperformance), willful violation of any law,
   rule or regulation (other than a law, rule or regulation relating to a
   traffic violation or similar offense), final cease-and-desist order,
   termination under the provisions of Section 2.7(b) and (c) or material
   breach of any provision of this Agreement.  

   2.5  Termination of Employment by the Bank Without Cause.

        The Bank may terminate Executive's employment hereunder without
   cause, in which case the Executive shall receive (a) his base salary under
   Section 1.3 hereof through the then remaining term of employment under
   Section 1.1, (b) his theretofore unpaid base salary for the period of
   employment up to the date of termination, (c) medical, dental and life
   insurance through the then remaining term of employment under Section 1.1
   consistent with the terms and conditions set forth in Section 1.4, to the
   extent the same can be provided under the insurance arrangements of the
   Bank in effect at the time of termination, (d) any other benefits to which
   Executive is entitled by law or the specific terms of the Bank's policies
   in effect at the time of termination of employment and (e) an amount equal
   to the product of  the Bank's annual aggregate contribution, for the
   benefit of the Executive in the fiscal year preceding termination, to all
   qualified retirement plans in which the Executive participated multiplied
   by the number of years in the initial term of employment under Section
   1.1.  The benefit in (e) under this Section 2.5 shall be in addition to
   any benefit payable from any qualified or non-qualified plans or programs
   maintained by the Company or the Bank at the time of termination.  If the
   Bank's medical and dental plans are not insured, the medical and dental
   benefit in (c) shall be accomplished by the Bank paying to Executive an
   additional cash amount equal to the COBRA premium for such coverage, plus
   taxes on such amount, so that Executive may purchase the coverage on an
   after-tax basis.

   2.6  Termination of Employment Due to Change in Control.

        (a)    If, at any time after the date hereof, a "Change in Control"
   (as hereinafter defined) occurs and within eighteen (18) months thereafter
   Executive's appointment as Vice President - Retail Sales and Service of
   the Company or his employment as Vice President - Retail Sales and Service
   of the Bank is involuntarily terminated (other than for Just Cause
   pursuant to Section 2.4) then the Executive shall be entitled to the
   benefits provided below.

               (i)     The Company shall promptly pay, or cause the Bank to
   pay, to the Executive an amount equal to the product of 2.0 times the
   Executive's "base amount" as defined in Section 280G(b)(3) of the Code
   (such "base amount" to be derived from Executive's compensation paid by
   the Company and the Bank).

               (ii)     During the term of this Agreement set forth in
   paragraph 1.1 (including any renewal term), the Executive, his dependents,
   beneficiaries and estate shall continue to be covered under all employee
   benefit plans of the Company and the Bank, including without limitation
   the Company's and the Bank's pension and retirement plans, life insurance
   and health insurance as if the Executive was still employed by the Bank
   during such period under this Agreement; provided that coverage under the
   medical and dental plans of the Company and the Bank shall be handled as
   set forth in Section 2.5 above.

               (iii)   If and to the extent that benefits or services credit
   for benefits under Section 2.6(a)(ii) above shall not be payable or
   provided under any such plans to the Executive, his dependents,
   beneficiaries and estate, by reason of his no longer being an employee of
   the Bank as a result of termination of employment, the Company shall
   itself, or shall cause the Bank to, pay or provide for payment of such
   benefits and service credit for benefits to the Executive, his dependents,
   beneficiaries and estate.  Any such payment relating to retirement shall
   commence on a date selected by the Executive which must be a date on which
   payments under the Company or Bank's qualified pension plan or successor
   plan may commence.

        (b)    (i)     Anything in this Agreement to the contrary
   notwithstanding, it is the intention of the Company, the Bank and the
   Executive that no portion of any payment under this Agreement, or payments
   to or for the benefit of the Executive under any other agreement or plan,
   be deemed an "Excess Parachute Payment" as defined in Section 280G of the
   Code, or its successors.  It is agreed that the present value of any
   payment to or for the benefit of the Executive in the nature of
   compensation, receipt of which is contingent on the occurrence of a Change
   in Control, and to which Section 280G of the Code applies (in the
   aggregate "Total Payments") shall not exceed an amount equal to one dollar
   less than the maximum amount that the Company and the Bank may pay without
   loss of deduction under Section 280(G)(a) of the Code.  Present value for
   purposes of this Agreement shall be calculated in accordance with Section
   280G(d)(4) of the Code.  Within sixty days (60) following the earlier of
   (1) the giving of notice of termination of employment or (2) the giving of
   notice by the Company to the Executive of its belief that there is a
   payment or benefit due the Executive, the Company, at the Company's
   expense, shall obtain the opinion of the Company's public accounting firm
   (the "Accounting Firm"), which opinion need not be unqualified, which sets
   forth: (a) the amount of the Base Period Income of the Executive (as
   defined in Code Section 280G), (b) the present value of Total Payments and
   (c) the amount and present value of any Excess Parachute Payments.  In the
   event that such opinion determines that there would be an Excess Parachute
   Payment, the payment hereunder shall be modified, reduced or eliminated as
   specified by the Executive in writing delivered to the Company within
   thirty (30) days of his receipt of such opinion or, if the Executive fails
   to so notify the Company, then as the Company shall reasonably determine,
   so that under the bases of calculation set forth in such opinion there
   will be no Excess Parachute Payment.  In the event that the provisions of
   Sections 280G and 4999 of the Code are repealed without succession, this
   Section shall be of no further force or effect.

               (ii)    In the event that the Accounting Firm is serving as
   accountant or auditor for the individual, entity or group effecting the
   Change in Control, the Executive shall appoint another nationally
   recognized public accounting firm to make the determinations required
   hereunder (which accounting firm shall then be referred to as the
   Accounting Firm under Section 2.6(b)).  All fees and expenses of the
   Accounting Firm shall be borne solely by the Company.  Any determination
   by the Accounting Firm shall be binding upon the Company and the
   Executive.

        (c)    For purposes of Section 2.6 of this Agreement, a "Change in
   Control" shall be deemed to have occurred if:

               (i)     a third person, including a "group" as defined in
   Section 13(d)(3) of the Securities Exchange Act of 1934 (as in effect on
   the date hereof), becomes the beneficial owner of shares of the Company
   having 20% or more of the total number of votes that may be cast for the
   election of directors of the Company, including for this purpose any
   shares beneficially owned by such third person or group as of the date
   hereof; or

               (ii)    as the result of, or in connection with, any cash
   tender or exchange offer, merger or other business combination, sale of
   assets or contested election, or any combination of the foregoing
   transactions (a "Transaction"), the persons who were directors of the
   Company before the Transaction shall cease to constitute a majority of the
   Board of Directors of the Company or any successor to the Company. (In the
   event of any reorganization involving the Company in a transaction
   initiated by the Company in which the shareholders of the Company
   immediately prior to such reorganization become the shareholders of a
   successor or ultimate parent company of the Company resulting from such
   reorganization and the persons who were directors of the Company
   immediately prior to such reorganization constitute a majority of the
   Board of Directors of such successor or ultimate parent, no "Change in
   Control" shall be deemed to have taken place solely by reason of such
   reorganization, notwithstanding the fact that the Company may have become
   the wholly-owned subsidiary of another Company in such reorganization and
   the Board of Directors thereof may have been reconstituted, and thereafter
   the term "Company" for purposes of this paragraph shall refer to such
   successor or ultimate parent company.); or

               (iii)   a third person, including a "group" as defined in
   Section 13(d)(3) of the Securities Exchange Act of 1934 (as in effect on
   the date hereof), acquires control, as defined in 12 C.F.R. Section 
   574.4, or any successor regulation, of the Company which would require the
   filing of an application for acquisition of control or notice of change in
   control in a manner set forth in 12 C.F.R. Section  574.3, or any
   successor regulation; or

               (iv)    The terms "termination" or  "involuntarily terminated"
   in this Agreement shall refer to the termination of the employment of
   Executive by the Bank without his express written consent.  In addition,
   for purposes of this Agreement, a material diminution  or interference
   with the Executive's duties, responsibilities and benefits as Vice
   President - Retail Sales and Service of the Company or the Bank shall be
   deemed and shall constitute an involuntary termination of employment to
   the same extent as express notice of such involuntary termination.  By way
   of example and not by way of limitation, any of the following actions, if
   unreasonable or materially adverse to the Executive shall constitute such
   diminution or interference unless consented to in writing by the
   Executive: (1) a change in the principal work place of the Executive to a
   location outside a twenty-five mile radius from the Company's headquarters
   at 420 South Koeller Street, Oshkosh, Wisconsin; (2) a material reduction
   in the secretarial or other administrative support of the Executive; (3) a
   material demotion of the Executive, a material reduction in the number or
   seniority of other Company or Bank personnel reporting to the Executive,
   or a reduction in the frequency with which, or in the nature of the
   matters with respect to which, such personnel are to report to the
   Executive, other than as part of a Company-wide or Bank-wide reduction in
   staff; and (4) a reduction or adverse change in the salary,  perquisites,
   benefits, contingent benefits or vacation time which had theretofore been
   provided to the Executive, other than as part of an overall program
   applied uniformly and with equitable effect to all executive officers of
   the Company or the Bank.

   2.7  Termination or Suspension of Employment as Required by Law.

        Notwithstanding anything in this Agreement to the contrary, the
   following provisions shall limit the obligation of the Bank to continue
   employing Executive, but only to the extent required by the applicable
   regulations of the OTS (12 C.F.R. Section  563.39), or similar succeeding
   regulations:

        (a)    If the Executive is suspended and/or temporarily prohibited
   from participating in the conduct of the Bank's affairs by a notice served
   under Section 8(e)(3) or (g)(1) of the Federal Deposit Insurance Act (12
   U.S.C.  Section  1818(e)(3) and (g)(1)) the Bank's obligations under this
   Agreement shall be suspended as of the date of service of notice, unless
   stayed by appropriate proceedings.  If the charges in the notice are
   dismissed, the Bank may in its discretion (i) pay the Executive all or
   part of the compensation withheld while its contract obligations hereunder
   were suspended and (ii) reinstate (in whole or in part) any of its
   obligations which were suspended.

        (b)    If the Executive is removed and/or permanently prohibited from
   participating in the conduct of the Bank's affairs by an order issued
   under Section 8(e)(4) or (g)(1) of the Federal Deposit Insurance Act (12
   U.S.C. Section  1818(e)(4) or (g)(1)) all obligations of the Bank under
   this Agreement shall terminate as of the effective date of the order.

        (c)    If the Bank is in default (as defined in Section 3(x)(1) of
   the Federal Deposit Insurance Act), the obligation to Executive hereunder
   shall terminate as of the date of default.

        (d)    All obligations under this Agreement may be terminated:  (i)
   by the Director of the Office of Thrift Supervision (the "Director") or
   his or her designee at the time the Federal Deposit Insurance Company
   enters into an agreement to provide assistance to or on behalf of the Bank
   under the authority contained in Section 13(c) of the Federal Deposit
   Insurance Act and (ii) by the Director, or his or her designee at the time
   the Director or such designee approves a supervisory merger to resolve
   problems related to operation of the Bank or when the Bank is determined
   by the Director to be in an unsafe or unsound condition.

        (e)    Termination pursuant to subparagraph (d) of this Section 2.7
   shall be treated as a termination by the Bank without cause entitling
   Executive to benefits payable under Section 2.5.  Termination pursuant to
   subparagraph (a), (b) or (c) shall be treated as a termination for Just
   Cause under Section 2.4.  Termination under this Section 2.7 shall not
   affect other rights hereunder which are vested at the time of termination.

   2.8  Limitation on Termination or Disability Pay.

        Any payments made to the Executive pursuant to this Agreement or
   otherwise are subject to and conditioned upon their compliance with 12
   U.S.C. Section  1828(k) and any regulations promulgated thereunder.

                                   ARTICLE III
                             LEGAL FEES AND EXPENSES

        The Company shall pay, or shall cause the Bank to pay, all legal fees
   and expenses which the Executive may incur as a result of the Company or
   the Bank contesting the validity or enforceability of this Agreement,
   provided that the Executive is the prevailing party in such contest or
   that any dispute may otherwise be settled in favor of the Executive.  The
   Executive shall be entitled to receive interest thereon for the period of
   any delay in payment from the date such payment was due at the rate
   determined by adding two hundred basis points to the six-month Treasury
   Bill rate.

                                   ARTICLE IV
                                 CONFIDENTIALITY

        Executive acknowledges that he now has, and in the course of his
   employment will have, access to important and confidential information
   regarding the business and services of the Company, the Bank and their
   subsidiaries, as well as similar information regarding OSB Financial and
   its subsidiaries relating to his previous employment by OSB Bank, and that
   the disclosure to, or the use of such information by, and business in
   competition with the Company, the Bank or their subsidiaries shall result
   in substantial and undeterminable harm to the Company, the Bank and their
   subsidiaries.  In order to protect the Company, the Bank and their
   subsidiaries against such harm and from unfair competition, Executive
   agrees with the Company and the Bank that while employed by the Bank and
   at any time thereafter, Executive will not disclose, communicate or
   divulge to anyone, or use in any manner adverse to the Company, the Bank
   or their subsidiaries any information concerning customers, methods of
   business, financial information or other confidential information of the
   Company, the Bank, their subsidiaries or similar information regarding OSB
   Financial and its subsidiaries, except for information as is in the public
   domain or ascertainable through common sources of public information
   (otherwise than as a result of any breach of this covenant by Executive).

                                    ARTICLE V
                               GENERAL PROVISIONS

   5.1  Inquiries Regarding Proposed Activities.

        In the event Executive shall inquire in writing of the Company
   whether any proposed action on the part of Executive would be considered
   by the Company or the Bank to be prohibited by or in breach of the terms
   of this Agreement, the Company shall have 30 days after receipt of such
   notice to express in writing to Executive its position with respect
   thereof and in the event such writing shall not be given to Executive,
   such proposed action, as set forth in the writing of the Executive, shall
   not be deemed to be a violation of or breach of this Agreement.

   5.2  No Duty of Mitigation.

        The Executive shall not be required to mitigate the amount of any
   payment or benefit provided for in this Agreement by seeking other
   employment or otherwise, nor shall the amount of any payment or benefit
   provided for in this Agreement be reduced by any compensation earned by
   the Executive as the result of employment by another employer, by
   retirement benefits after the date of termination of this Agreement or
   otherwise.
     
   5.3  Successors.

        This Agreement may be assigned by the Company or the Bank to any
   other business entity that is directly or indirectly controlled by the
   Company or the Bank.  This Agreement may not be assigned by the Company or
   the Bank except in connection with a merger involving the Company or the
   Bank or a sale of substantially all of the assets of the Company or the
   Bank, and the respective obligations of the Company and the Bank provided
   for in this Agreement shall be the binding legal obligations of any
   successor to the Company or the Bank by purchase, merger, consolidation,
   or otherwise.  This Agreement may not be assigned by the Executive during
   his life, and upon his death will be binding upon and inure to the benefit
   of his heirs, legatees and the legal representatives of his estate.

   Bank, as the case may be), or to such other address as either party may

   5.6  Severability.

                               _____________, 1997


   OSB Financial Corp.
   420 South Koeller Street
   Oshkosh, Wisconsin   54902

               Re:     Agreement and Plan of Merger, dated as of November __,
                       1996, Between FCB Financial Corp. and OSB Financial
                       Corp.

   Gentlemen:

               We have served as special counsel to FCB Financial Corp., a
   Wisconsin corporation ("FCB"), in connection with the preparation,
   execution and delivery of the Agreement and Plan of Merger, dated November
   __, 1996 (the "Agreement"), and the Plan of Merger, dated ________, 1997
   (the "Plan of Merger"), by and between FCB and OSB Financial Corp., a
   Wisconsin corporation ("OSB"), providing for the merger of OSB with and
   into FCB (the "Merger").  This opinion is being delivered to you pursuant
   to Section 7.2(d) of the Agreement.  Capitalized terms used herein and not
   otherwise defined shall have the meaning given them in the Agreement.  

               As counsel for FCB, we have reviewed the Agreement, the Plan
   of Merger and the Registration Statement on Form S-4 [, as amended] of FCB
   (Registration No. 333-________) (the "Registration Statement")  filed with
   the Securities and Exchange Commission (the "Commission"), and also have
   examined and relied upon such other documents and instruments, and
   certificates of public officials, and have made such other investigations
   and inquiries as we have deemed necessary or appropriate for purposes of
   this opinion.  For purposes of this opinion, we have assumed, without
   investigation: (a) the legal capacity of each natural person; (b) the full
   power and authority of each person, other than FCB and its officers, to
   execute, deliver and perform each document heretofore executed and
   delivered or hereafter to be executed and delivered, and to do each other
   act heretofore done or hereafter to be done by such person; (c) the due
   authorization, execution and delivery by each person, other than FCB and
   its officers, of each document heretofore executed and delivered or
   hereafter to be executed and delivered by such person; (d) the legality,
   validity, binding effect and enforceability as to each person, other than
   FCB and its officers, of each document heretofore executed and delivered
   or hereafter to be executed and delivered, and of each other act
   heretofore done or hereafter to be done by such person; (e) the
   genuineness of each signature (other than signatures of FCB officers) on
   and the completeness of each document submitted to us as an original; (f)
   the conformity to, and the authenticity of, the original of each document
   submitted to us as a copy; (g) no modification of any provision of any
   document, nor waiver of any right or remedy; and (h) no exercise of any
   right or remedy other than in a commercially reasonable and conscionable
   manner and in good faith.

               As to questions of fact material to our opinion which have not
   been independently established (which includes the factual basis for those
   parts of our opinion which are stated to be qualified with the statement
   "to our knowledge" or words of similar import), we have relied upon,
   without independent verification, the accuracy of the relevant facts
   stated in the certificates or comparable documents of officers of FCB and
   the FCB Subsidiaries and upon the accuracy of the representations and
   warranties contained in the Agreement.  Although we have made no
   independent investigation or verification of each matter set forth
   therein, nothing has come to our attention indicating that such reliance
   by us or by you is not justified.  In addition, and particularly with
   respect to numbered paragraph 10 below, we wish to advise you that we have
   made no special investigation as to the factual basis for our opinion,
   such as a search of the dockets or records of any court or governmental
   office, agency or authority to determine if any such proceedings are
   pending or orders have been entered involving FCB or the FCB Subsidiaries.

               The opinions hereafter expressed are qualified to the extent
   that the rights, interests and remedies under the Agreement, the Plan of
   Merger, or any other documents, exhibits or schedules delivered in
   connection with the transactions contemplated thereby may be subject to or
   affected by: (a) any bankruptcy, insolvency, bank conservatorship or
   receivership or similar laws affecting creditors' rights and remedies
   generally, and the enforcement thereof; (b) the unavailability of, or any
   limitation on the availability of, any particular right or remedy (whether
   in a proceeding in equity or at law) because of general principles of
   equity; and (c) any limitation insofar as indemnification and contribution
   provisions thereof may be limited by applicable law.  In addition, we
   express no opinion as to the enforceability of Sections 1.10 and 8.3 of
   the Agreement.

               On the basis of and subject to the foregoing and the
   qualifications stated below, we are of the opinion that: 

        1.     FCB is a corporation validly existing under the laws of the
   State of Wisconsin and has the corporate power to own all of its
   properties and assets and to carry on its business as it is now being
   conducted as described in the Registration Statement.  FCB is a registered
   savings and loan holding company under the Home Owners' Loan Act.

        2.     FCB Bank is validly existing as a savings association under
   the laws of the United States and has the corporate power to own all of
   its properties and assets and to carry on its business as it is now being
   conducted as described in the Registration Statement. 

        3.     Each of the FCB Subsidiaries (other than FCB Bank) is a
   corporation validly existing under the laws of its respective jurisdiction
   of incorporation and each has the corporate power to own all of its
   properties and assets and to carry on its business as it is now being
   conducted as described in Registration Statement.

        4.     The authorized capitalization of FCB consists of (i)
   15,000,000 shares of common stock, $.01 par value per share, of which
   ____________ shares are issued and outstanding and ________ shares are
   held in the treasury; and (ii) 5,000,000 shares of preferred stock, $.01
   par value per share, of which no shares are issued and outstanding.  All
   of the issued shares of common stock, $.01 par value, of FCB have been
   duly authorized and validly issued and are fully paid and nonassessable
   (except with respect to assessability as provided in Section
   180.0622(2)(b) of the Wisconsin Business Corporation Law (the "WBCL")).  
   To our knowledge, except for the rights of OSB  under the Agreement, the
   Plan of Merger, and the OSB Stock Option Agreement and except for options
   granted and outstanding under FCB's 1993 Stock Option and Incentive Plan,
   there are no options, agreements, contracts or other rights in existence
   to purchase or acquire from FCB any shares of capital stock of FCB.

        5.     FCB has full corporate power and authority to execute and
   deliver the Agreement and the Plan of Merger and to consummate the
   transactions contemplated thereby.  The execution and delivery and
   performance of the Agreement and the Plan of Merger and the consummation
   of the transactions contemplated thereby have been duly and validly
   approved by the Board of Directors of FCB and, to our knowledge, in the
   case of the Agreement and the Plan of Merger, by the shareholders of FCB,
   these being the only corporate authorizations required under the Articles
   of Incorporation and Bylaws of FCB and the WBCL.  The Agreement and the
   Plan of Merger have been duly and validly executed and delivered by FCB
   and constitute valid and binding obligations of FCB, enforceable against
   FCB in accordance with their respective terms.

        6.     The execution, delivery and performance by FCB of the
   Agreement and the Plan of Merger will not violate the Articles of
   Incorporation or Bylaws of FCB.

        7.     Upon issuance in the manner and upon the terms contemplated in
   the Agreement and the Plan of Merger, the shares of common stock, $.01 par
   value, of FCB to be issued in the Merger will be duly authorized, validly
   issued, fully paid, and nonassessable (except with respect to
   assessability as provided in Section 180.0622(2)(b) of the WBCL).
    
        8.     At the time that the Registration Statement was declared
   effective by the Commission, the Registration Statement (other than the
   financial statements and supporting schedules and the financial and
   statistical information or data included therein, as to which we express
   no opinion) complied as to form in all material respects with the
   requirements of the Securities Act of 1933, as amended, and the rules and
   regulations of the Commission thereunder.

        9.     No consents or approvals of, or filings or registrations with
   any Governmental Entity are necessary in connection with the execution and
   delivery by FCB of the Agreement and the Plan of Merger and the
   consummation by FCB of the Merger and the other transactions contemplated
   thereby that have not been received or obtained as of the date hereof,
   except where the failure to obtain such consent or approval or to make
   such filing or registration will not have or be reasonably likely to have
   a Material Adverse Effect on FCB.

        10.    To our knowledge, there are no actions, suits or proceedings,
   pending or threatened against or affecting FCB or the FCB Subsidiaries, at
   law or in equity or before or by any governmental department, commission,
   board, bureau, agency or instrumentality, or before any arbitrator of any
   kind which, in our opinion, based upon such knowledge, if the relief
   sought in the pleadings in such actions, suits and proceedings were
   granted or if the threatened claims were accrued in full, are likely to
   have a Material Adverse Effect on FCB.

               We are qualified to practice law in the State of Wisconsin and
   we do not purport to be experts on the law other than that of the State of
   Wisconsin and the Federal laws of the United States of America.  We

               Re:     Agreement and Plan of Merger, dated as of November __,
                       1996, Between FCB Financial Corp. and OSB Financial
                       Corp.

   Gentlemen:

               We have served as special counsel to OSB Financial Corp., a
   Wisconsin corporation ("OSB"), in connection with the preparation,
   execution and delivery of the Agreement and Plan of Merger, dated November
   __, 1996 (the "Agreement"), and the Plan of Merger, dated ________, 1997
   (the "Plan of Merger"), by and between OSB and FCB Financial Corp., a
   Wisconsin corporation ("FCB"), providing for the merger of OSB with and
   into FCB (the "Merger").  This opinion is being delivered to you pursuant
   to Section 7.3(d) of the Agreement.  Capitalized terms used herein and not
   otherwise defined shall have the meaning given them in the Agreement.  

               As counsel for OSB, we have reviewed the Agreement, the Plan
   of Merger and the Registration Statement on Form S-4 [, as amended] of FCB
   (Registration No. 333-________) (the "Registration Statement")  filed with
   the Securities and Exchange Commission (the "Commission"), and also have
   examined and relied upon such other documents and instruments, and
   certificates of public officials, and have made such other investigations
   and inquiries as we have deemed necessary or appropriate for purposes of
   this opinion.  For purposes of this opinion, we have assumed, without
   investigation: (a) the legal capacity of each natural person; (b) the full
   power and authority of each person, other than OSB and its officers, to
   execute, deliver and perform each document heretofore executed and
   delivered or hereafter to be executed and delivered, and to do each other
   act heretofore done or hereafter to be done by such person; (c) the due
   authorization, execution and delivery by each person, other than OSB and
   its officers, of each document heretofore executed and delivered or
   hereafter to be executed and delivered by such person; (d) the legality,
   validity, binding effect and enforceability as to each person, other than
   OSB and its officers, of each document heretofore executed and delivered
   or hereafter to be executed and delivered, and of each other act
   heretofore done or hereafter to be done by such person; (e) the
   genuineness of each signature (other than signatures of OSB officers) on
   and the completeness of each document submitted to us as an original; (f)
   the conformity to, and the authenticity of, the original of each document
   submitted to us as a copy; (g) no modification of any provision of any
   document, nor waiver of any right or remedy; and (h) no exercise of any
   right or remedy other than in a commercially reasonable and conscionable
   manner and in good faith.

               As to questions of fact material to our opinion which have not
   been independently established (which includes the factual basis for those
   parts of our opinion which are stated to be qualified with the statement
   "to our knowledge" or words of similar import), we have relied upon,
   without independent verification, the accuracy of the relevant facts
   stated in the certificates or comparable documents of officers of OSB and
   the OSB Subsidiaries and upon the accuracy of the representations and
   warranties contained in the Agreement.  Although we have made no
   independent investigation or verification of each matter set forth
   therein, nothing has come to our attention indicating that such reliance
   by us or by you is not justified.  In addition, and particularly with
   respect to numbered paragraph 8 below, we wish to advise you that we have
   made no special investigation as to the factual basis for our opinion,
   such as a search of the dockets or records of any court or governmental
   office, agency or authority to determine if any such proceedings are
   pending or orders have been entered involving OSB or the OSB Subsidiaries.

               The opinions hereafter expressed are qualified to the extent
   that the rights, interests and remedies under the Agreement, the Plan of
   Merger, or any other documents, exhibits or schedules delivered in
   connection with the transactions contemplated thereby may be subject to or
   affected by: (a) any bankruptcy, insolvency, bank conservatorship or
   receivership or similar laws affecting creditors' rights and remedies
   generally, and the enforcement thereof; (b) the unavailability of, or any
   limitation on the availability of, any particular right or remedy (whether
   in a proceeding in equity or at law) because of general principles of
   equity; and (c) any limitation insofar as indemnification and contribution
   provisions thereof may be limited by applicable law.  In addition, (i)
   with respect to numbered paragraph 5 below, we express no opinion as to
   the adequacy of the Registration Statement or Joint Proxy Statement and
   (ii) we express no opinion as to the enforceability of Sections 1.10 and
   8.3 of the Agreement.

               On the basis of and subject to the foregoing and the
   qualifications stated below, we are of the opinion that: 

        1.     OSB is a corporation validly existing under the laws of the
   State of Wisconsin and has the corporate power to own all of its
   properties and assets and to carry on its business as it is now being
   conducted as described in the Registration Statement.  OSB is a registered
   savings and loan holding company under the Home Owners' Loan Act.

        2.     OSB Bank is validly existing as a savings association under
   the laws of the United States and has the corporate power to own all of
   its properties and assets and to carry on its business as it is now being
   conducted as described in the Registration Statement. 

        3.     Each of the OSB Subsidiaries (other than OSB Bank) is a
   corporation validly existing under the laws of its respective jurisdiction
   of incorporation and each has the corporate power to own all of its
   properties and assets and to carry on its business as it is now being
   conducted as described in the Registration Statement, except that if RWFV,
   Inc. has been dissolved it has paid all outstanding franchise and other
   taxes due and owing by it.

        4.     The authorized capitalization of OSB consists of (i) 7,000,000
   shares of common stock, $0.01 par value per share, of which ____________
   shares are issued and outstanding and ________ shares are held in the
   treasury; and (ii) 1,000,000 shares of preferred stock, $0.01 par value
   per share, of which no shares are issued and outstanding.  All such issued
   shares of common stock have been duly authorized and validly issued and
   are fully paid and nonassessable (except with respect to assessability as
   provided in Section 180.0622(2)(b) of the Wisconsin Business Corporation
   Law (the "WBCL")).   To our knowledge, except for the rights of  FCB 
   under the Agreement, the Plan of Merger, FCB Stock Option Agreement and
   except for options granted and outstanding under OSB's 1992 Stock Option
   and Incentive Plan, there are no options, agreements, contracts or other
   rights in existence to purchase or acquire from OSB any shares of capital
   stock of  OSB.

        5.     OSB has full corporate power and authority to execute and
   deliver the Agreement and the Plan of Merger and to consummate the
   transactions contemplated thereby.  The execution and delivery and
   performance of the Agreement and the Plan of Merger and the consummation
   of the transactions contemplated thereby have been duly and validly
   approved by the Board of Directors of OSB and, to the best of our
   knowledge, in the case of the Agreement and Plan of Merger, by the
   shareholders of OSB, these being the only corporate authorizations
   required under the Articles of Incorporation and Bylaws of OSB and the
   WBCL.  The Agreement and the Plan of Merger have been duly and validly
   executed and delivered by OSB and constitute valid and binding obligations
   of OSB, enforceable against OSB in accordance with their respective terms.

        6.     The execution, delivery and performance by OSB of the
   Agreement and the Plan of Merger will not violate the Articles of
   Incorporation or Bylaws of OSB.

        7.     No consents or approvals of, or filings or registrations with,
   any Governmental Entity are necessary in connection with the execution and
   delivery by OSB of the Agreement and the Plan of Merger and the
   consummation by OSB of the Merger and the other transactions contemplated
   thereby that have not been received or obtained as of the date hereof,
   except where the failure to obtain such consent or approval or to make
   such filing or registration will not have or be reasonably likely to have
   a Material Adverse Effect on OSB.
    
        8.     To our knowledge, there are no actions, suits or proceedings,
   pending or threatened against or affecting OSB or the OSB Subsidiaries, at
   law or in equity or before or by any governmental department, commission,
   board, bureau, agency or instrumentality, or before any arbitrator of any
   kind which, in our opinion, based upon such knowledge, if the relief
   sought in the pleadings in such actions, suits and proceedings were
   granted or if the threatened claims were accrued in full, are likely to
   have a Material Adverse Effect on OSB.

               This opinion is being furnished to you solely for your benefit
   in connection with the Agreement.  It may not be relied upon by, nor a
   copy of it delivered to any other party, without our prior written
   consent.  This opinion is based upon our knowledge of the law and facts as
   of the date hereof, and we assume no duty to communicate with you with
   respect to any matter that comes to our attention hereafter.

                                      Very truly yours,

                                      SCHIFF HARDIN & WAITE
