The Company also reported that it expects third quarter 2001 core and net earnings per share of $0.48, which is in line with First Call analysts' consensus estimates. The Company also reaffirmed that, based on current market and economic conditions, it anticipates its full year core earnings, exclusive of one-time costs related to the merger of SJNB Financial Corp. and other nonrecurring items, to meet the First Call analysts' consensus estimates. David L. Kalkbrenner, President and Chief Executive Officer of Greater Bay Bancorp, commented, "The anticipated third quarter earnings remain consistent with the guidance we published in June of this year at the time we announced our pending merger with SJNB Financial Corp. Because of that merger, we suspended our stock repurchase program so that we could account for the merger as a pooling-of-interests. Although the SEC granted some emergency exemptions from the pooling requirements, other SEC rules prevent us from resuming our stock repurchase program as we are in the middle of soliciting proxies for the shareholder meetings to vote on the merger. If not for the status of the merger, we would likely be in the market purchasing our stock, since, at current levels, we believe it would make an excellent investment for us." A press release outlining the third quarter financial results will be distributed at 5:45 am PDT on October 17, 2001. The conference call will begin at 8:00 am PDT on October 17, 2001 and will last for approximately one hour. -more- Greater Bay Bancorp Expects to Meet Consensus Earnings Estimates for Third Quarter October 8, 2001 Page 2 Investors have the opportunity to listen to the conference call live over the Internet through Street Events, Inc., at http://www.streetevents.com.
