                       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.
