   Item 5.   Other Events

             FCB Financial Corp., a Wisconsin corporation ("FCB) and parent
   company of Fox Cities Bank, F.S.B., and OSB Financial Corp., a Wisconsin
   corporation ("OSB") and parent company of Oshkosh Savings Bank, F.S.B.,
   have entered into an Agreement and Plan of Merger, dated as of November
   13, 1996 (the "Merger Agreement"), providing for the merger of OSB with
   and into FCB (the "Merger"), pursuant to a merger of equals transaction.
   FCB will be the surviving corporation in the Merger (the "Surviving 
   Corporation") and will continue to operate under the name FCB Financial 
   Corp.  The Merger Agreement has been approved by the Boards of Directors 
   of both of the constituent companies and, subject to shareholder approval 
   of both FCB and OSB shareholders as well as various regulatory approvals,
   the Merger is expected to be completed during the second quarter of 1997.  
   The banking subsidiaries of the two merger partners are also expected to 
   merge and will thereafter operate under the name Fox Cities Bank, F.S.B. 
   (the "Surviving Bank").

             Under the terms of the Merger Agreement, each share of common
   stock, $.01 par value, of OSB (the "OSB Common Stock") issued and
   outstanding immediately prior to the effectiveness of the Merger (the
   "Effective Time") will (except as otherwise provided below) be cancelled
   and converted into the right to receive 1.46 shares (the "OSB Exchange
   Ratio") of the common stock, $.01 par value, of FCB (the "FCB Common
   Stock") plus cash in lieu of any fractional shares.  All shares of OSB
   Common Stock (i) owned by OSB as treasury stock, (ii) owned by the OSB
   Management Development and Recognition Plans and not allocated to
   participants thereunder or (iii) owned by FCB will be cancelled and no FCB
   Common Stock or other consideration will be given in exchange therefor. 
   Shares of FCB Common Stock which are issued and outstanding at the time of
   the Merger will not be affected by the Merger and will remain outstanding
   as the same number of shares of the Surviving Corporation.  Each option
   granted by OSB under the terms of the OSB Financial Corp. 1992 Stock
   Option and Incentive Plan (the "OSB Option Plan") which is outstanding and
   unexercised prior to the Effective Time will be converted into an option
   to purchase shares of FCB Common Stock equal to the product of the number
   of shares of OSB Common Stock subject to the original option and the OSB
   Exchange Ratio (with fractional shares being rounded up to the nearest
   whole number) and will have an exercise price per share equal to the
   exercise price under the original option divided by the OSB Exchange Ratio
   (with the exercise price rounded down to the nearest whole cent).

             At the Effective Time, it is expected that the quarterly cash
   dividend of the Surviving Corporation will remain at the current FCB level
   of $.18 per share.  Subsequent dividend policy will be developed by the
   Board of Directors of the Surviving Corporation.

             The Merger is subject to customary closing conditions,
   including, without limitation, the receipt of required shareholder
   approvals of FCB and OSB; the receipt of regulatory approvals, including
   approval of the Office of Thrift Supervision, to consummate the Merger;
   and the receipt of opinions of counsel that the Merger will qualify as a
   tax-free reorganization.  In addition, the Merger is conditioned upon the
   effectiveness of a registration statement to be filed by FCB with the
   Securities and Exchange Commission with respect to shares of FCB Common
   Stock to be issued in the Merger.  It is anticipated that shareholders
   will vote upon the Merger at special meetings of shareholders held by both
   FCB and OSB in the second quarter of 1997.

             The Merger Agreement contains certain covenants of the parties
   pending the consummation of the Merger.  Generally, the parties must carry
   on their businesses in the ordinary course consistent with past practice,
   may not declare dividends on common stock other than regular quarterly
   cash dividends and may not issue any capital stock except pursuant to
   outstanding stock options.  The Merger Agreement also contains
   restrictions on, among other things, charter and bylaw amendments,
   acquisitions, dispositions of assets, incurrence of indebtedness, certain
   increases in employee compensation and benefits, the satisfaction of
   material claims, liabilities or obligations, and material changes to the
   investment securities portfolio or gap position of FCB or OSB.  (See
   Article V of the Merger Agreement.)

             The Merger Agreement provides that, after the Effective Time,
   the corporate headquarters of the Surviving Corporation will be located in
   Oshkosh, Wisconsin.  The Surviving Corporation's Board of Directors, which
   will be divided into three classes, will consist of a total of 14
   directors, 7 of whom will be selected by FCB and 7 of whom will be
   selected by OSB.  Mr. Donald D. Parker, the current Chairman of the Board,
   President and Chief Executive Officer of FCB, will serve as Chairman of
   the Board of Directors of the Surviving Corporation and the Surviving
   Bank.  Mr. James J. Rothenbach, the current President and Chief Executive
   Officer of OSB, will serve as President and Chief Executive Officer of the
   Surviving Corporation and the Surviving Bank.  Mr. Phillip J. Schoofs, the
   current Vice President and Treasurer of FCB, will serve as the Vice
   President, Treasurer and Chief Financial Officer of the Surviving
   Corporation and the Surviving Bank.  (See Article I of the Merger
   Agreement.)

             The Merger Agreement may be terminated under certain
   circumstances, including (i) by mutual consent of the parties; (ii) by
   either party within 20 days of the date of the Merger Agreement (30 days
   in the case of environmental issues) if such party determines, upon
   completion of its due diligence, that the Merger would not be in the best
   interests of such party or its shareholders; (iii) by either party if the
   Merger is not consummated by September 30, 1997; (iv) by either party if
   either of FCB's or OSB's shareholders vote against the Merger or if any
   state or federal law or court order prohibits the Merger; (v) by the non-
   breaching party if there exist breaches of any representations or
   warranties contained in the Merger Agreement or in the Stock Option
   Agreements (as hereinafter defined), which breaches, individually or in
   the aggregate, would result in a material adverse effect on the breaching
   party and which are not cured within thirty (30) days after notice; (vi)
   by the non-breaching party if there occurs a material breach of any
   covenant or agreement in the Merger Agreement or in the Stock Option
   Agreements which is not cured within thirty (30) days after notice; (vii)
   by either party if the Board of Directors of the other party shall
   withdraw or adversely modify its recommendation of the Merger or shall
   approve or recommend any competing transaction; or (viii) by either party,
   under certain circumstances, as a result of a third party tender offer or
   business combination proposal which such party, pursuant to its directors'
   fiduciary duties, is, in the opinion of such party's counsel and after the
   other party has first been given an opportunity to make concessions and
   adjustments in the terms of the Merger Agreement, required to accept. 
   (See Article VIII of the Merger Agreement.)

             The Merger Agreement provides that if a breach described in
   clause (v) or (vi) of the previous paragraph occurs, then, if such breach
   is not willful, the non-breaching party will be entitled to reimbursement
   of its out-of-pocket expenses, not to exceed $200,000.  In the event of a
   willful breach, the non-breaching party will be entitled to its out-of-
   pocket expenses (which shall not be limited to $200,000) and any remedies
   it may have at law or in equity, and provided that if, at the time of the
   breaching party's willful breach, there shall have been a third party
   tender offer or business combination proposal which shall not have been
   rejected by the breaching party or withdrawn by the third party, then such
   breaching party at the time of termination of the Merger Agreement, will
   pay to the non-breaching party an additional aggregate fee equal to $1.0
   million.  The Merger Agreement also requires payment of an aggregate
   termination fee of $1.0 million, together with reimbursement of out-of-
   pocket expenses, by one party (the "Target Party") to the other party, if
   the Merger Agreement is terminated (a) as a result of the acceptance by
   the Target Party of a third party tender offer or business combination
   proposal, (b) as a result of the Target Party's material failure to
   convene a meeting of shareholders while a third party tender offer or
   business combination proposal remains outstanding, (c) following a failure
   of the shareholders of the Target Party to approve the Merger while a
   third party tender offer or business combination proposal remains
   outstanding or, (d) the Board of Directors of either party to the Merger
   withdraws or modifies its recommendation of the Merger Agreement, approves
   or recommends any business combination with a third party, or resolves to
   take any of the foregoing actions.  The termination fees (exclusive of any
   amounts paid for the reimbursement of expenses) payable by FCB or OSB
   under the foregoing provisions plus the aggregate amount which could be
   payable by FCB or OSB under the Stock Option Agreements may not exceed
   $1.5 million in the aggregate.

             Concurrently with the Merger Agreement, FCB and OSB have also
   entered into reciprocal stock option and trigger payment agreements (the
   "Stock Option Agreements") granting each other irrevocable options to
   purchase up to 19.9% of the other party's shares of common stock issued
   and outstanding as of November 13, 1996 at an exercise price of $24.375
   per share of OSB Common Stock and $18.875 per share of FCB Common Stock. 
   Each option is exercisable only if the Merger Agreement should become
   terminable in a case where a termination fee would be payable to the
   holder of the option.  A party whose option becomes exercisable (the
   "Exercising Party") will have the right to receive, under certain
   circumstances, the difference between the exercise price and the then
   current market price of the shares subject to option and may request that
   the other party repurchase from it all or any portion of the Exercising
   Party's option at the price specified in the Stock Option Agreements. 
   (See the Stock Option Agreements.)

             The Merger, which will be accounted for as a purchase
   transaction for accounting purposes, will create the largest independent
   thrift institution headquartered in the Fox River Valley area of
   Wisconsin.  It is expected that the Surviving Corporation will continue to
   provide full service banking from each of the existing 13 Fox Cities Bank,
   F.S.B. and Oshkosh Savings Bank, F.S.B. offices located in various cities
   throughout the region.  Based on data as of September 30, 1996, the
   Surviving Corporation will have total assets in excess of $500 million,
   total loans of approximately $390 million, total deposits of approximately
   $310 million and shareholders' equity of approximately $75 million.  The
   Surviving Corporation also will have in excess of $220 million of mortgage
   loans that it originated and services for others.  It is currently
   estimated that the combination of various functions and other economies of
   scale when implemented will result in annual pre-tax savings for the
   Surviving Corporation on a net basis of approximately $800,000.
