Item 5.  Other Events.
         ------------

                  On March 5, 2000, North Fork Bancorporation ("North Fork")
announced its intention to commence an offer to exchange each outstanding share
of common stock of Dime Bancorp, Inc. ("Dime") for 0.9302 of a share of North
Fork common stock and $2.00 in cash.

                  As previously announced, on March 6, 2000, the board of
directors of Dime concluded that North Fork's offer is inadequate and not in the
best interests of Dime and its stockholders and reaffirmed its recommendation
that Dime stockholders vote "FOR" adoption of the merger agreement between Dime
and Hudson United Bancorp.

                  This current report on Form 8-K includes (1) a Supplement,
dated March 7, 2000, to the proxy statement of Dime and prospectus relating to
Dime common stock dated February 9, 2000, (2) certain presentation materials for
investors, and (3) a consent of Dime's financial advisor. Each of these is
incorporated by reference into this Item 5.
