1 SECURITIES AND EXCHANGE COMMISSION WASHINGTON, D.C. 20549 FORM 8-K CURRENT REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 DATE OF REPORT: JUNE 25, 2001 (Date of earliest event reported) DIME BANCORP, INC. (Exact name of registrant as specified in its charter) DELAWARE 001-13094 11-3197414 (State or other jurisdiction (Commission File Number) (IRS Employer of incorporation) Identification No.) 589 Fifth Avenue New York, New York 10017 (Address of principal executive offices) (Zip Code) Registrant's telephone number, including area code: (212) 326-6170 NOT APPLICABLE (Former name or former address, if changed since last report) 2 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 $40,8366 times 0.284659 (which represents the cash portion of the aggregate merger consideration). The exchange ratio per Dime share will be equal to the per share consideration value determined pursuant to the preceding sentence divided by the average Washington Mutual common stock price during the Measurement Period. The outcome of the per share consideration adjustment and the cash/stock election procedure will not change the aggregate number of Washington Mutual shares (except, as noted above, to the extent that there is a change in the number of Dime shares outstanding) or the aggregate amount of cash to be paid by Washington Mutual. Potential adjustments to the per share merger consideration are illustrated below. 3 - ---------------- -------------- ----------------- ---------------- ----------------- ---------------- ---------------- ------------ WM Pre- Percentage Aggregate Aggregate Aggregate Cash Value of Stock closing Change in WM Cash Value of Stock Consideration Consider- Consider- Implied Average Stock Stock Consideration Consideration ($MM) (3) ation per ation per Dime Exchange Price(1) Price(2) ($MM) ($MM) (3) Dime Share(4) Share(4) Ratio(4) - ---------------- -------------- ----------------- ---------------- ----------------- ---------------- ---------------- ------------ $48.6150 +25% $1,429 $4,488 $5,917 $48.1396 $48.1396 0.9902x 46.6704 +20 1,429 4,309 5,738 46.6790 46.6790 1.0002 44.7258 +15 1,429 4,129 5,558 45.2184 45.2184 1.0110 42.7812 +10 1,429 3,950 5,379 43.7578 43.7578 1.0228 40.8366 +5 1,429 3,770 5,199 42.2972 42.2972 1.0358 38.8920 - 1,429 3,591 5,020 40.8366 40.8366 1.0500 36.9474 -5 1,429 3,411 4,840 39.3760 39.3760 1.0657 35.0028 -10 1,429 3,232 4,661 37.9154 37.9154 1.0832 33.0582 -15 1,429 3,052 4,481 36.4548 36.4548 1.1028 31.1136 -20 1,429 2,872 4,301 34.9942 34.9942 1.1247 29.1690 -25 1,429 2,693 4,122 33.5336 33.5336 1.1496 - ---------------- -------------- ----------------- ---------------- ----------------- ---------------- ---------------- ------------ (1) Average closing stock price of Washington Mutual common stock during the Measurement Period.

(4) Stock consideration per Dime share and cash consideration per Dime share valued using the pre-closing average stock price of Washington Mutual common stock during the Measurement Period (see column 1). The Merger is intended to constitute a reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended, and is to be accounted for as a purchase. Consummation of the Merger is subject to customary conditions.
