o    On February 12, 2004, Deutsche Bank AG submitted a Statement of Beneficial
     Ownership on Schedule 13G reporting their ownership of shares of Common
     Stock of SPG PROPERTIES INC/MD/ (CIK# 0000912564). It was subsequently
     determined that the beneficial ownership and total voting shares held of
     the Common Stock were attributed to the incorrect issuer. This filing is
     being made to correct that error, and correctly report holdings of Simon
     Property Group Inc. (CIK 0001063761).
