D.    The Mortgage encumbers, among other things, Mortgagor’s leasehold interest in the parcel(s) of real property described on Exhibit A to the Existing Mortgage (also attached hereto as Exhibit A) (the “Land”; the Land, together with all of the buildings, improvements, structures, and fixtures now or subsequently located on the Land, being the “Real Estate”) pursuant to that certain Real Property Lease Agreement between The Dayton Power and Light Company, an Ohio corporation (“DP&L”), as lessor and fee simple owner of the Land, and Mortgagor, as lessee, dated as of October 29, 2015 (the “Ground Lease”), a memorandum of which is recorded as File Number 2015-00061861 in the Montgomery County, Ohio Records.
