Three Proxy Advisory Firms Support WaMu Proposals at Upcoming Special Shareholders’ Meeting

Seattle, WA — Washington Mutual, Inc. (NYSE: WM) today announced that independent proxy advisory firms Institutional Shareholder Services, Inc. (ISS), Glass, Lewis & Co. and PROXY Governance Inc. have recommended that shareholders vote for both of the company’s proposals related to the recent $7 billion capital raise at the upcoming Special Meeting of Shareholders on Tuesday, June 24, 2008.

On April 8, 2008, the Company announced that it had entered into definitive agreements to raise approximately $7 billion through the direct sale of equity securities to affiliates of TPG Capital and to other institutional investors. The transactions closed in April 2008.

At the meeting, WaMu shareholders will vote on two proposals. The first is whether to approve an increase in the number of authorized shares of common stock to permit the conversion of the preferred stock issued in the company’s recent capital raising transaction into, and the ability to exercise warrants issued in that transaction for, common stock. The second proposal is whether to approve the conversion and exercise of these securities. The WaMu Board of Directors has recommended that shareholders vote “FOR” each proposal.
