                   FCB FINANCIAL CORP. AND OSB FINANCIAL CORP.
                            ANNOUNCE MERGER OF EQUALS


        November 14, 1996.  FCB Financial Corp. (Nasdaq National Market: 
   FCBF), Neenah, Wisconsin, parent of Fox Cities Bank, F.S.B., and OSB
   Financial Corp. (Nasdaq National Market:  OSBF), Oshkosh, Wisconsin,
   parent of Oshkosh Savings Bank, F.S.B., today announced the signing of a
   definitive agreement pursuant to which the two companies will be merged. 
   The resulting company will operate under the name FCB Financial Corp. and
   will be headquartered in Oshkosh, Wisconsin.

        The merger, which will combine two of the oldest banking institutions
   in Wisconsin's Fox River Valley, will create the largest independent
   thrift institution headquartered in the area.  Based on data as of
   September 30, 1996, the combined institution 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 combined company also will have in excess
   of $220 million of mortgage loans that it originated and services for
   others.

        The "merger of equals" transaction will be structured as a tax-free,
   stock-for-stock merger and accounted for as a purchase transaction.  In
   the merger, holders of OSB Financial Corp. common stock will receive 1.46
   shares of FCB common stock for each OSB share they own.  Holders of shares
   of FCB Financial Corp. common stock will continue to hold the same number
   of FCB shares after the merger.  FCB's and OSB's total outstanding shares
   at September 30, 1996 were 2.46 million and 1.11 million, respectively. 
   The shares of the combined company are expected to continue to trade on
   The Nasdaq Stock Market.  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.

        At the effective time of the merger, it is expected that the
   quarterly cash dividend of the combined company will remain at the current
   FCB Financial Corp. level of $.18 per share.  Based on the exchange rate
   in the merger, this would equate to an annual per share dividend increase
   for holders of OSB Financial Corp. common stock of approximately 64%.

        "This merger of equals provides an opportunity for both revenue
   enhancement and cost savings which we believe will result in an accretion
   in earnings per share for the combined company," said Donald D. Parker,
   Chairman of the Board, President and Chief Executive Officer of FCB
   Financial Corp. and James J. Rothenbach, President and Chief Executive
   Officer of OSB Financial Corp.

        It is currently estimated that the combination of various functions
   and other economies of scale when implemented will result in annual pre-
   tax cost savings for the combined company on a net basis of approximately
   $800,000.  "Although there is potential for substantial cost savings, our
   strategy will focus on revenue enhancement from our strong mortgage
   business as well as an expansion of various other services, including full
   service business banking, commercial lending, consumer lending, indirect
   lending, brokerage and investment services and trust services," said
   Rothenbach.

        Both Rothenbach and Parker commented that the merger will align two
   companies that are committed to community involvement and locally
   delivered, high quality customer service.  "This combination provides the
   strength and resources to be a truly outstanding community financial
   center," said Rothenbach.  "This will enable us to expand the products and
   services we offer both individual consumers and businesses throughout our
   market areas," added Parker.

        Upon completion of the merger, Parker will serve as Chairman of the
   combined company and Rothenbach will serve as President and Chief
   Executive Officer.  The Board of Directors of the combined company will
   initially consist of an equal number of representatives from both merger
   partners.

        The combined company will continue to provide full service banking
   from each of the existing 13 offices located in Appleton (3), Berlin,
   Darboy, Menasha, Neenah (2), Oshkosh (2), Ripon, Wautoma and Winneconne,
   Wisconsin.

        The merger is subject to approval of the shareholders of both FCB
   Financial Corp. and OSB Financial Corp. and is also subject to various
   regulatory approvals.  Based on the anticipated timetable for the receipt
   of such approvals, it is currently expected that the merger will be
   completed during the second quarter of 1997.
