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

         As previously announced, 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.

         On March 6, 2000, North Fork filed a lawsuit in the Delaware Court of
Chancery against Dime, members of Dime's board of directors and Hudson United
Bancorp ("Hudson"), challenging a number of the provisions in the Dime-Hudson
merger agreement and alleging breaches of fiduciary duties by Dime's board of
directors. The complaint seeks, among other things, an order invalidating
certain provisions of the Dime-Hudson merger agreement.

         Several class action lawsuits were also filed by stockholders of Dime
in the same court.

         Dime intends to defend these actions vigorously and believes that they
are without merit.
