16. No Other Modification. Landlord and Tenant agree that except as otherwise specifically modified in this Amendment, the Lease has not been modified, supplemented, amended, or otherwise changed in any way and the Lease remains in full force and effect

between the parties hereto as modified by this Amendment.
