FOR IMMEDIATE RELEASE


                  DIME BANCORP RESPONDS TO ISS RECOMMENDATION

ISS IGNORES SUBSATNTIAL BENEFITS OF WARBURG PINCUS TRANSACTION

NEW YORK - July 10, 2000 - Dime Bancorp, Inc. (NYSE: DME) today issued the
following statement in response to the Institutional Shareholder Services Inc.'s
(ISS) report:

"We vigorously disagree with ISS' recommendation. Unfortunately, ISS has failed
to realize the substantial benefits of our agreement with Warburg Pincus and the
compelling opportunity to increase stockholder value for Dime shareholders.
Similarly, in interpreting this election as a referendum on Dime's Board's
decision not to negotiate with North Fork, it is clear the ISS has also ignored
the innumerable weaknesses of North Fork's proposal. In making their choice in
voting for directors, Dime stockholders should consider the following:

*    "Dime stockholders are being given a choice between two value-producing
     alternatives: tendering into the Dutch Auction and receiving cash value
     consistent with, if not superior to, the uncertain and risky value in North
     Fork's proposal or remaining invested alongside Warburg Pincus and with
     Tony Terracciano, who both have unparalleled records of producing superior
     returns and value for investors.

*    "An exhaustive, two-month-long review of available strategic options, which
     included a careful analysis of the current merger and acquisition market
     for financial institutions, as well as discussions with potential bidders,
     demonstrated quite clearly that a sale of the company now would not
     optimize stockholder value.

*    "Going forward, Dime will continue to evaluate strategic opportunities as
     they become available.

*    "Since the day before North Fork made its proposal through today, its stock
     has underperformed the S&P Regional Bank index by 20%.

"The weakness of North Fork's proposal is amply demonstrated by two key
considerations. First, Warburg Pincus is investing in Dime in a non-takeover
transaction at values consistent with North Fork's effort to take over the
entire company. This suggests that North Fork's proposal is seriously
inadequate. Second, North Fork filed its exchange offer four months ago, and as
of June 27, 2000 a mere 17% of Dime shares had been tendered into that offer.
Clearly, Dime stockholders themselves recognize the poor value that North Fork
is attempting to thrust upon them.

                                 - continued -

"Dime's management and board, including Tony Terracciano, our new chairman, are
committed to implementing an accelerated growth strategy that we believe will
produce superior returns for Dime stockholders, while preserving the opportunity
to attract a control premium for Dime shares in the future. We urge Dime
stockholders to reelect the director nominees."

         Investors are urged to read (1) Dime's solicitation/recommendation
statement filed with the Securities and Exchange Commission on Schedule 14D-9 on
March 21, 2000 with respect to North Fork Bancorporation Inc.'s hostile exchange
offer, (2) Dime's proxy statement relating to the 2000 annual stockholders
meetings, and (3) Dime's tender offer statement on Schedule TO when filed with
the Securities and Exchange Commission in connection with Dime's proposed Dutch
Auction tender offer, as well as any amendments or supplements to these
statements when they become available, because they contain important
information. Each of these documents has been or will be filed with the SEC and
investors may obtain them for free from the SEC at the SEC's website
(www.sec.gov) or from Dime by directing such request to: Dime Bancorp, Inc.,
Investor Relations Dept., 589 Fifth Avenue, New York, NY 10017, telephone
1-212-326-6170, or to Innisfree M&A Incorporated at 1-888-750-5834.

         Certain statements in Dime's press releases may be forward-looking. A
variety of factors could cause Dime's actual results and experience to differ
materially from the anticipated results or other expectations expressed in such
forward-looking statements. The risks and uncertainties that may affect the
transactions described above, as well as the operations, performance,
development, and results of Dime's business, include litigation, interest rate
movements, competition from both financial and non-financial institutions,
changes in applicable laws and regulations, the timing and occurrence (or
non-occurrence) of transactions and events that may be subject to circumstances
beyond Dime's control and general economic conditions.

         Dime believes that "operating earnings" basis information, when taken
in conjunction with reported results, provide useful information in evaluating
performance on a comparable basis, although operating earnings are not currently
a required basis for reporting financial results under generally accepted
accounting principles.
