GREATER BAY BANCORP AND
PACIFIC RIM BANCORPORATION ANNOUNCE COMPLETION
OF STRATEGIC BUSINESS COMBINATION

     PALO ALTO, Calif. -- Greater Bay Bancorp ("GBBK" on Nasdaq), the $1.2
billion in assets holding company for Cupertino National Bank, Mid-Peninsula
Bank, Peninsula Bank of Commerce, Venture Banking Group and Greater Bay Trust
Company, announced that the merger with Pacific Rim Bancorporation, holding
company for Golden Gate Bank, San Francisco, California, was completed on May 8,
1998.  With the completion of the merger, Golden Gate Bank will become a wholly
owned subsidiary of Greater Bay Bancorp.  The combined entity will continue to
focus on serving the greater Bay Area through its ten combined office locations
from San Francisco to San Jose.  The transaction furthers the strategic emphasis
of Greater Bay Bancorp in becoming the preeminent independent community
financial services company based in the San Francisco Bay Area market.  Based on
March 31, 1998 financial information, the combined company will have total
assets of approximately $1.3 billion and equity of approximately $80 million.

     David L. Kalkbrenner, President and Chief Executive Officer of Greater Bay
Bancorp commented, "We are excited about having Golden Gate Bank join the
Greater Bay Bancorp family, as the business combination allows Greater Bay
Bancorp to strategically position itself in San Francisco, a key financial
center for California and the United States."  Mr. Kalkbrenner continued, "The
combination furthers Greater Bay Bancorp's strategic plan to build its Super
Community Banking franchise, which significantly benefits our clients and our
shareholders."

     James Woolwine, President and Chief Executive Officer of Golden Gate Bank
commented, "We firmly believe this merger is very beneficial for our current
clients and  provides significant opportunities to attract new client
relationships through the expanded services available as a member of the Greater
Bay Bancorp family."

     Leo K. W. Lum, Chairman of Pacific Rim Bancorporation and Golden Gate Bank
commented, "With the continued out of state mergers of California based business
banks, it is apparent that San Francisco is an excellent market for a
relationship focused organization like Greater Bay Bancorp and our merger could
not have been planned at a better time to take advantage of this opportunity."
Effective as of May 26, 1998, Mr. Lum will join the Board of Directors of
Greater Bay Bancorp.

 
     The terms of the agreement provide that Pacific Rim Bancorporation's sole
shareholder will receive approximately 475,000 shares of Greater Bay Bancorp
stock (approximately 950,000 shares after the two-for-one stock split for
shareholders of record as of April 30, 1998) in a tax-free exchange.  The total
value  of the Greater Bay Bancorp shares issued approximates $30.9 million.  The
merger will be accounted for as a "pooling of interests."
