                          FORWARD LOOKING INFORMATION
- --------------------------------------------------------------------------------
This presentation contains estimates of future operating results for both Dime
Bancorp, Inc. ("Dime") and North American Mortgage Company ("North American") on
a stand-alone and pro forma combined basis and estimates of financial condition
and cost savings on a combined basis. These estimates constitute forward-looking
statements (within the meaning of the Private Securities Litigation Reform Act
of 1996), which involve significant risks and uncertainties. Actual results may
differ materially from the results discussed in these forward-looking
statements. Factors that might cause such a difference include, but are not
limited to, the following: (1) expected cost savings from the acquisition may
not be fully realized or realized within the expected time frame; (2) revenues
following the proposed acquisition may be lower than expected; (3) costs or
difficulties related to the integration of the businesses of Dime and North
American may be greater than expected; (4) changes in the interest rate
environment may reduce interest margins; and (5) general economic conditions,
either nationally or in the states in which the combined company will be
concentrated, may be less favorable than expected. Further information which
could affect the financial results of Dime after the proposed merger is
discussed in Dime's Reports on Form 10-K for the period ended December 31, 1996
and Form 10-Q for the period ended March 31, 1997 and Forms 8-K as of April 23,
1997, April 25, 1997, May 9, 1997 and June 16, 1997, as filed with the
Securities and Exchange Commission, to which reports reference is hereby made.
