These tests indicate that the Company's core banking systems are ready for the year 2000 date change. According to David L. Kalkbrenner, president and chief executive officer of Greater Bay Bancorp, "The testing completed in the project included the Company's core application software for its deposit, loan and trust computer systems, as well as the electronic funds transfers system with the Federal Reserve. With the successful completion of these tests, we are confident that the century date change will not impact our ability to serve our clients' financial needs." Greater Bay Bancorp performed this testing on its actual bank computer systems and at its off-site backup facility. The dates were moved forward to 20 significant dates that pose potential problems for the systems, such as September 9, 1999, December 31, 1999, January 3, 2000 and February 29, 2000. In each case, the tested systems performed without error. As part of its year 2000 preparations, the Company also monitors the year 2000 readiness of its key clients and vendors to mitigate risk to Greater Bay Bancorp.
