                                  (PIERS) Units

This document  supplements the prospectus  dated September 4, 2001,  relating to
the units. Each unit consists of:

     o    a preferred  security  issued by Washington  Mutual Capital Trust 2001
          (the "Trust"), having a stated liquidation amount of $50, representing
          an  undivided  beneficial  interest in the assets of the Trust,  which
          assets consist solely of subordinated  debentures issued by Washington
          Mutual,  Inc. each of which has a principal amount at maturity of $50,
          a stated  maturity of July 1, 2041 and, at any time, an accreted value
          as described in the prospectus; and

     o    a warrant to  purchase  at any time prior to the close of  business on
          May 3, 2041, 1.2081 shares of common stock of Washington  Mutual.  The
          exercise  price of each  warrant on the initial  date of issuance  was
          $32.33  and  will  accrete  on a  daily  basis  as  described  in  the
          prospectus to $50 on the expiration date.

At any time after  issuance of the units,  the  preferred  security  and warrant
components  of  each  unit  may be  separated  by  the  holder  and  transferred
separately.  Thereafter,  a  separated  preferred  security  and  warrant may be
combined to form a unit.
