         This Current Report on Form 8-K (including information included or
incorporated by reference herein) contains forward-looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995. Such
forward-looking statements include, but are not limited to, statements about (i)
the benefits of the merger between Washington Mutual Corporation and Dime
Bancorp, Inc., including future financial and operating results, cost savings
and accretion to reported earnings that may be realized from the merger; (ii)
Washington Mutual's and Dime's plans, objectives, expectations and intentions
and other statements contained in this presentation that are not historical
facts; and (iii) other statements identified by words such as "expects,"
anticipates," "intends," "plans," "believes," "seeks," "estimates," or words of
similar meaning. These forward-looking statements are based upon the current
beliefs and expectations of Washington Mutual's and Dime's management and are
inherently subject to significant business, economic and competitive
uncertainties and continegencies, many of which are beyond our control.

                                       -2-

In addition, such forward-looking statements are subject to assumptions with
respect to future business strategies and decisions that are subject to change.
Actual results may differ materially from the anticipated results discussed in
the forward-looking statements.

         The following factors, among others, could cause actual results to
differ materially from the anticipated results or other expectations expressed
in the forward-looking statements: (1) the business of Washington Mutual and
Dime may not be combined successfully, or such combination may take longer, be
more difficult, time-consuming or costly to accomplish than expected; (2) the
expected cost savings from the merger may not be fully realized or may take
longer to realize than expected; (3) operating costs, customer loss and business
disruption following the merger; (4) governmental approvals of the merger may
not be obtained, or adverse regulatory conditions may be imposed in connection
with governmental approvals of the merger; (5) the stockholders of Dime may fail
to approve the merger; (6) adverse governmental or regulatory policies may be
enacted; (7) the interest rate environment may further compress margins and
adversely affect net interest income; (8) the risks associated with continued
diversification of assets and adverse changes to credit quality; (9) competition
from other financial services companies in Washington Mutual's and Dime's
markets; (10) the concentration of Washington Mutual's operations in California
may adversely affect results if the California economy or real estate market
declines; and (11) the risk of an economic slowdown that would adversely affect
credit quality and loan originations. Additional factors, that could cause
actual results to differ materially from those expressed in the forward-looking
statements are discussed in Washington Mutual's and Dime's reports (such as
Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports
on Form 8-K) filed with the Securities and Exchange Commission and available on
the SEC's Internet site (http://www.sec.gov). All subsequent written and oral
forward-looking statements concerning the proposed transaction or other matters
attributable to Washington Mutual or Dime or any person acting on their behalf
are expressly qualified in their entirety by the cautionary statements above.
Washington Mutual and Dime do not undertake any obligation to update any
forward-looking statement to reflect circumstances or events that occur after
the date the forward-looking statements are made.
