(3) Borrower shall terminate the Ground Lease and the Operating Lease and Agent, for the ratable benefit of the Lenders, shall have a mortgage lien on the consolidated estates of Borrower and Operating Company existing on the Property prior to the date of Transfer (the “REIT Mortgage”), and an assignment of leases and rents with respect to all Leases (the “REIT ALR”), each substantially in the forms of the Mortgage and the Assignment of Leases constituting the Loan Documents (or each constituting the existing Mortgage and Assignment of Leases as spread to encumber such consolidated estates). In addition, the landlord’s interest in the Observatory Lease shall be assigned to Op Sub, as landlord, and the existing Observatory Tenant, which shall be one hundred percent (100%) owned, directly or indirectly, by the REIT or the Op, as tenant (the “REIT Observatory Tenant”), shall remain as tenant thereunder.

8. Continued Force and Effect. This Second Amendment is not intended to, and shall not be construed to, effect a novation, and except as expressly provided in this Second Amendment, the Loan Agreement has not been modified, amended, cancelled, terminated, released, satisfied, superseded or otherwise invalidated by execution of this Second Amendment.
