Item 5.  Other Events

         On May 21, 2002, the Company announced that it will acquire Golden
State Bancorp Inc. ("GSB") in a transaction in which the Company will pay
approximately $16.40 in cash and .5234 of a share of the Company's common
stock for each share of GSB common stock delivered at closing. GSB
stockholders will be entitled to elect to receive the merger consideration in
shares of the Company common stock or cash, subject to certain limitations.
Based on closing prices on May 21, 2002, the total transaction value is
approximately $5.8 billion on a fully diluted basis.

         In connection with the Merger Agreement, certain stockholders of GSB,
which have voting power over approximately 31.5% of the outstanding shares of
GSB common stock, have entered into a Securityholders Agreement (the
"Securityholders Agreement") pursuant to which they have agreed to vote their
shares in favor of the transaction.

         The transaction is expected to be completed in the fourth quarter of
2002. It is subject to a number of regulatory approvals and the approval of
Golden State stockholders. The merger is intended to be tax-free.

         The Merger Agreement, the Securityholders Agreement and the press
release announcing the transaction are attached hereto as exhibits and are
incorporated herein by reference.
