Registrant from Saxon  Mortgage,  Inc.  ("SMI"),  an affiliate of the Registrant
which  originated or acquired the Mortgage Loans from various  mortgage  banking
institutions.  The  Mortgage  Loans  are  secured  by  liens  on  single  family
residential   properties,   including   investment   properties  (which  may  be
condominiums,  one family residences,  one to four family residences or homes in
planned  unit  developments).  The  Mortgage  Loans will be serviced by Meritech
Mortgage Services, Inc., an affiliate of the Registrant.
