Item 5.           Other Events.

         As previously disclosed, on June 25, 2001, Dime Bancorp, Inc. ("Dime")
announced that it had entered into a definitive Agreement and Plan of Merger
with Washington Mutual, Inc. ("Washington Mutual"), dated as of June 25, 2001
(the "Merger Agreement"), pursuant to which Dime will merge with and into
Washington Mutual, with Washington Mutual as the surviving corporation (the
"Merger").

         As a result of the Merger, each outstanding share of Dime common stock
will be converted into the right to receive merger consideration as provided for
in the Merger Agreement. The aggregate consideration paid in the transaction
will consist of approximately $1.4 billion in cash and approximately 92.3
million shares of Washington Mutual common stock, representing approximately
28.5% and 71.5%, respectively, of the current value of the aggregate merger
consideration (not including merger consideration relating to Dime employee
stock options initially valued at $177 million). To the extent that the number
of Dime shares outstanding changes as a result of, for example, the exercise of
options, the aggregate number of shares of Washington Mutual common stock to be
issued will change accordingly but the aggregate cash consideration to be paid
will not change.

         The transaction initially values Dime's common stock at $40.84 per
share, based on a 1.05 exchange ratio and a price of $38.89 per Washington
Mutual common share, the average five-day price for Washington Mutual common
shares prior to announcement of the Merger. If the average closing stock price
of Washington Mutual common stock for the ten consecutive full trading days
ending on the tenth business day prior to the closing date (the "Measurement
Period") were to equal $38.89 per share, Dime stockholders could choose to
receive, for each Dime share they own, either Washington Mutual common shares at
a 1.05 exchange ratio or $40.84 per share in cash, subject to proration. If,
however, the average Washington Mutual common stock price during the Measurement
Period does not equal $38.89, the exchange ratio and the per share value of the
cash consideration will each be adjusted so that the per share value of the
stock consideration and the per share value of the cash consideration remain
equal.


        The value of the merger consideration per Dime share will equal the
sum of

         o  an amount equal to (i) the average of the closing stock prices for
            Washington Mutual's common stock during the Measurement Period times
            (ii) 1.05 times (iii) 0.715341 (which represents the stock portion
            of the aggregate merger consideration), plus

         o  $40,8366 times 0.284659 (which represents the cash portion of the
            aggregate merger consideration).


         The exchange ratio per Dime share will be equal to the per share
consideration value determined pursuant to the preceding sentence divided by the
average Washington Mutual common stock price during the Measurement Period. The
outcome of the per share consideration adjustment and the cash/stock election
procedure will not change the aggregate number of Washington Mutual shares
(except, as noted above, to the extent that there is a change in the number of
Dime shares outstanding) or the aggregate amount of cash to be paid by
Washington Mutual. Potential adjustments to the per share merger consideration
are illustrated below.
