          such matters relating to the Security Agreements and the other Loan
          Documents, as the Administrative Agent may request (and the Borrower
          hereby instructs its counsel to deliver such opinions to the
          Administrative Agent for the benefit of the Lenders);

                    (vii) as applicable, a Mortgage with respect to each
          Mortgaged Property executed on behalf of the record owner of such
