Item 5.  OTHER EVENTS.

         The Registrant issued a press release dated June 6, 1996, announcing
the signing of a definitive agreement for a merger of Cupertino National
Bancorp, Cupertino, California, with and into Registrant and that Registrant
will change its name to Greater Bay Bancorp concurrent with closing of the
merger.  Cupertino shareholders will receive .81522 of a share of Registrant's
common stock for each share of Cupertino common stock in a tax-free exchange to
be accounted for as a "pooling-of-interests", resulting in approximately 51%
ownership by Registrant and approximately 49% ownership by Cupertino of the
surviving corporation, Greater Bay Bancorp.

         In connection with the merger, the Registrant and Cupertino granted
each other options to purchase up to 19% of the outstanding shares of each
other's common stock under certain circumstances in the event the transaction is
terminated.  The merger is expected to be completed in the fourth quarter of
1996, subject to shareholder and regulatory approvals.

         The foregoing description is qualified by reference to the Amended and
Restated Agreement and Plan of Reorganization and Merger dated June 26, 1996
attached hereto as Exhibit 2.1 and press release dated June 6, 1996 attached
hereto as Exhibit 99.1, each incorporated herein by reference.
