I need to do a UCC secured party search in the state of Washington to
find out who Washington Mutual Inc.'s (and their subsidiaries) debtors
are in Washington in their commercial banking division. The names of
their subsidiaries are as follows: Washington Mutual Bank, FA,
Washington Mutual Bank, Washington Mutual Bank fsb., Washington Mutual
Finance Corporation, Long Beach Mortgage Company, WM Financial
Services, Inc.
