FOR IMMEDIATE RELEASE

NORTH FORK DEFERS DECISION ON
DIME EXCHANGE OFFER

MELVILLE, N.Y. - SEPTEMBER 26, 2000 - NORTH FORK BANCORPORATION, INC. (NYSE:NFB) announced today that it had planned, at its regularly scheduled Board of Directors meeting today, to consider terminating or extending its pending exchange offer to acquire Dime Bancorp, Inc., which is currently scheduled to expire on September 29, 2000. However, the North Fork Board decided to defer consideration of these matters because it learned yesterday that the Board of Governors of the Federal Reserve System was scheduled to consider North Fork's application to acquire Dime at its meeting tomorrow, September 27, 2000. The Board of Directors of North Fork plans to reconvene on September 28, 2000 at 4:30 p.m. to continue its deliberations.
