         Watsonville,   CA.  December  21,  2001.  Monterey  Bay  Bancorp,  Inc.
("Company"), the holding company for Monterey Bay Bank ("Bank"), today announced
the adoption of a stock  repurchase  program with an authorization to acquire up
to 114,035  shares of its common stock,  equivalent to 3.3% of the common shares
currently outstanding.

         The  repurchases  will  be  made  in  open-market  transactions  or  in
privately  negotiated  transactions  pursuant  to the  terms  of  the  Company's
repurchase  program.  Repurchased  shares will become Treasury Stock and will be
utilized for general  corporate  and other  purposes,  including the issuance of
shares in connection with the exercise of stock options.

         Commenting  on the  announcement,  C. Edward  Holden,  Chief  Executive
Officer  and  President,  stated,  "This  repurchase  authorization  updates and
completes a 10.0% repurchase authorization first announced in December 1998. The
strategic  and  financial  progress  achieved  in the past year has  placed  the
Company in the position of being able to resume stock  repurchases,  which since
the  initial  public  offering  in 1995 have  totaled  in excess of 1.2  million
shares.  Having  an  active  stock  repurchase  authorization   complements  the
Company's  focus on  stockholder  value.  Directors are paid their retainer fees
exclusively  in Company common stock and stock based  compensation  represents a
significant portion of Management's total compensation."

         The  Company's  common  stock is listed on the NASDAQ  National  Market
under  the  symbol  "MBBC".  The  Company  and the  Bank  are  headquartered  in
Watsonville, California. The Bank operates through its administrative offices in
Watsonville and eight full service  branches located in the Greater Monterey Bay
Area of Central California.
