Washington Mutual Announces Resignation of Deanna Oppenheimer

SEATTLE, WA — Washington Mutual Inc. (NYSE:WM) today announced the resignation of Deanna W. Oppenheimer, President of its Retail Banking group, who will leave the company on March 1 for new business ventures.

Over the next two months, Oppenheimer will work closely with incoming President and Chief Operating Officer Steve Rotella to transition her responsibilities and ensure the group’s continued success.

“I respect Deanna’s decision and greatly appreciate her countless contributions to Washington Mutual’s success over the years,” said Kerry Killinger, the company’s chairman and chief executive officer. “Under her direction, our retail banking operation has had phenomenal growth and become a recognized leader in our industry. We wish her the best in her new endeavors.”

Oppenheimer’s departure comes at a time when the company has just completed its business plan for 1999 – 2004, and is embarking on its new five-year strategic plan. Killinger said the Retail Banking group has a very talented and capable leadership team in place to continue its strong momentum. He emphasized that Oppenheimer’s departure will not change the company’s overall Retail Banking strategy.

The company said that it remains focused on executing its core strategies; including:

• Continuing to grow its superior retail banking model, and opening approximately 250 new retail banking stores each year for the foreseeable future;

• Transforming the company’s mortgage business and maintaining a leading national position in mortgage lending;

• Continuing to grow its commercial business, including its market-leading multi-family lending operation and;

• Maintaining risk management as a top priority.

“My decision to leave the company comes after many months of careful consideration,” Oppenheimer said. “During my 20 years with Washington Mutual, I’ve had the honor of helping to create one of the nation’s top retail banking franchises. But, I have accomplished what I set out to do over the past two decades. Today, the retail banking leadership team has never been so seasoned and they are working at peak effectiveness to achieve the company’s new five-year plan. The retail bank is in very capable hands.”
