have also assumed the legal capacity of all natural persons,  the genuineness of
all  signatures on all  documents  examined by us, the authority of such persons
signing on behalf of the  parties  thereto  other than the  Company  and the due
authorization,  execution and delivery of all  documents by the parties  thereto
other than the Company.  As to certain factual  matters  material to the opinion
