                     NORTH FORK EXTENDS EXPIRATION DATE
                       OF ITS EXCHANGE OFFER FOR DIME


 MELVILLE, N.Y. -- MARCH 23, 2000 - NORTH FORK BANCORPORATION, INC.
 (NYSE:NFB) issued a statement today announcing that it had extended the
 expiration date of its exchange offer for all outstanding shares of common
 stock of Dime Bancorp, Inc. (NYSE:DME) to 12:00 midnight, New York City
 time, on Wednesday, May 31, 2000.

 North Fork extended the expiration date of its offer until the end of May
 in light of the second postponement of Dime's stockholder meeting to
 consider the proposed merger with Hudson United Bancorp, this time to May
 17, 2000, and North Fork's expectation that it will receive Federal Reserve
 Board approval for its offer in the latter part of May.  Failure of the
 Dime stockholders to approve the proposed merger with Hudson United and
 receipt of Federal Reserve Board approval would satisfy two conditions of
 North Fork's offer.

 As of 12:00 midnight, New York City time, on Wednesday, March 22, 2000, no
 shares of Dime common stock had been tendered in the offer.  As previously
 reported, North Fork commenced its exchange offer last week.

 North Fork also announced that Dime filed a lawsuit against North Fork and
 its directors in the United States District Court for the Eastern District
 of New York alleging claims under the federal securities laws based on what
 Dime believes are material misstatements and omissions in the proxy
 solicitation and exchange offer materials filed by North Fork with the
 Securities and Exchange Commission.  Dime's claim seeks injunctive and
 other relief.  North Fork believes that Dime's claims are without merit and
 intends to contest the action vigorously.

 Investors and security holders are advised to read North Fork's proxy
 statement with respect to North Fork's solicitation of proxies against the
 proposed Dime/Hudson merger and North Fork's registration statement with
 respect to its exchange offer for Dime common stock, each as filed with the
 Securities and Exchange Commission, and any amendments or supplements to
 either of them, because each of these documents contains important
 information.  Investors and security holders may obtain a free copy of the
 proxy statement, the exchange offer registration statement and other
 documents filed by North Fork with the SEC at the SEC's Internet web site
 at www.sec.gov.  The proxy statement, the exchange offer registration
 statement and such other documents may also be obtained free of charge by
 overnight mail or direct electronic transmission by calling North Fork's
 proxy solicitor, D.F. King & Co., Inc., toll-free at 1-800-755-7250.
