interests in the Trustor or the Trustee.

Each issuer of an underlying  security,  or guarantor thereof, or successor thereto, as applicable,  which
represents  ten percent  (10%) or more of the aggregate  principal  amount of all  securities  held by the

thereof, or successor thereto,  as applicable,  please see its periodic and current reports filed with the
Securities and Exchange Commission (the "Commission").  Such reports and other information  required to be
