NORTH FORK SEES MAJOR VICTORY OVER DIME BANCORP
AT DIME ANNUAL MEETING

NEW YORK, N.Y. - JULY 14, 2000 - NORTH FORK BANCORPORATION, INC. (NYSE:NFB) said today that Dime Bancorp, Inc.'s shareholders have voted by a margin of greater than 2 to 1 to reject Dime's Board nominees at Dime's Annual Meeting held earlier today. North Fork said it delivered to the independent inspectors of election proxies voting to withhold authority for Dime's director nominees totaling approximately 54.6 million shares, or more than 70% of the shares represented at the meeting.

"We are very gratified by the overwhelming show of support we have received from Dime's shareholders," said John A. Kanas, Chairman, President and Chief Executive Officer of North Fork. "This vote should send a strong and unambiguous message to Dime's Board of Directors that Dime's shareholders do not support Dime's status quo strategy and that Dime's shareholders want Dime to commence merger negotiations with North Fork immediately. Unfortunately, in light of the repeated unconscionable conduct on the part of Dime's board, as evidenced most recently by its outrageous, value destroying transaction with Warburg Pincus, we are unable to be optimistic that such negotiations will occur.

"The good news is that because Dime's nominees have not been reelected, a majority of Dime's board will now be up for reelection no later than Dime's 2001 annual meeting. However, as is typical of Dime's disregard of its shareholders, Dime evidently is now taking the position that its nominees will continue to serve for another three-year term, even though a majority of its shareholders voting at the annual meeting have voted otherwise. Accordingly, we have no choice but to commence litigation in Delaware Chancery Court seeking an order declaring Dime's position invalid."
