(A) The Greater Bay Bancorp (the "Company") Board of Directors currently has 19 members, many of whom were added to the Board as a result of bank acquisitions during the past eight years.  The Board undertook a review of the size and structure of the Board, especially in view of the charter consolidation of the Company's subsidiary banks that occurred in 2004.  As a result, the Board believes that it would function more efficiently if the size of the Board were reduced to a target range of 12 to 14 members.<p>At its regular meeting on January 25, 2005, the Board decided to offer a one-time early retirement benefit to directors in the amount of the fees they were paid during 2004 for Board and committee service.  The Company expects several directors to retire in the first quarter of 2005 under this program.  <p>(B) At its meeting on January 24, 2005, the Compensation Committee of the Company's Board of Directors approved a new form of Director Nonstatutory Stock Option Agreement pursuant to the Company's 1996 Stock Option Plan, as amended and restated.  The form of such agreement is included herein as Exhibit 10.1.  <p>(C) The Company filed the Executive Supplemental Compensation Benefits Agreement between David L. Kalkbrenner and the Company with its quarterly report on Form 10-Q for the quarter ended March 31, 2004.  Since that filing, the Company discovered that an incorrect version of Schedule C to that agreement was inadvertently included in the filing.
