                      BAY AREA BANCSHARES ANNOUNCE MERGER
                                        
     PALO ALTO, CA; January 26, 1999 -- Greater Bay Bancorp (Nasdaq: GBBK), Palo
Alto, California, and Bay Area Bancshares (OTC Bulletin Board:BYAR), Redwood
City, California, announced today the signing of a definitive agreement for a
merger of the two companies.  Following the transaction, Bay Area Bank, a wholly
owned subsidiary of Bay Area Bancshares, will operate as a wholly owned
subsidiary of Greater Bay Bancorp, along with Greater Bay Bancorp's other bank
subsidiaries, Cupertino National Bank, Mid-Peninsula Bank, Peninsula Bank of
Commerce and Golden Gate Bank.  The combined company will have total assets of
approximately $1.8 billion and equity of approximately $107 million.

     The terms of the agreement provide for the Bay Area Bancshares shareholders
to receive shares of Greater Bay Bancorp stock in a tax-free exchange for their
shares of Bay Area Bancshares.  For each outstanding share of Bay Area
Bancshares, Greater Bay Bancorp will issue 1.38682 shares if the average closing
price of its stock is $30.00 or more, or 1.44271 shares if the average closing
price of its stock is less than $30.00 upon completion of the merger.  Following
the merger, the shareholders of Bay Area Bancshares will own approximately 12.7%
of the combined company, after giving effect to all outstanding options.

     The merger is expected to be accretive to Greater Bay Bancorp's earnings in
1999 based on reductions in operating expenses and revenue enhancements
resulting from an expanded product line and increased lending capacity that can
be utilized at Bay Area Bank.  Management of the organizations believe that
significant opportunities exist to enhance the spectrum of financial services
offered to both existing and future clients of Bay Area Bank while also
increasing market penetration in the San Francisco Peninsula market areas.

     Greater Bay Bancorp's Board of Directors will be expanded to 15 members
with the addition of one current director of  Bay Area Bancshares.   The Board
of Directors of Bay Area Bank will continue and will include David L.
Kalkbrenner, President and Chief Executive 

 
Officer of Greater Bay Bancorp. Frank Bartaldo, Jr., President and Chief
Executive Officer of Bay Area Bank, will remain in that capacity.

     John Gatto and Duncan Matteson, Co-Chairmen of Greater Bay Bancorp said,
"With the merger of Bay Area Bancshares, Greater Bay Bancorp continues its
successful super-community banking philosophy.  We are very pleased to add
another quality community bank to the Greater Bay family."  Mr. Kalkbrenner
added,  "The merger with Bay Area Bancshares allows Greater Bay Bancorp to
affiliate with an organization that has an excellent reputation and performance
record, while strengthening our position in our primary target market area."

     Robert R. Haight, Chairman of the Board of Bay Area Bancshares, commented,
"Bay Area Bank was established in 1979 and has long been considered one of the
region's top independent banks.  By combining with Greater Bay Bancorp, Bay Area
Bank will enhance its ability to offer a wide range of financial services to its
clients and to increase its lending capacity and market presence."  Mr. Bartaldo
added, "Bay Area Bank is reporting its eleventh consecutive year of record
earnings today.  The Bank's earnings for 1998 increased $533,000 or 29% to
$2,395,000, resulting in a return on average equity of 20% and a return on
average assets of 1.74%.  Bay Area Bancshares ended the year with $155 million
in assets representing an increase of $33 million or 27% during the year."

     The merger is subject to certain conditions, including the approval of Bay
Area Bancshares' shareholders and regulatory approval, and will be accounted for
as a pooling of interests.  Subject to those conditions, the merger is expected
to be completed late in the first quarter of 1999 or early in the second quarter
of 1999.
