Blanket Policy.

Further, to the extent the policies are maintained pursuant to a blanket insurance policy that covers more than one location within a radius of the Leased Property equal to (a) with respect to property coverage, the lesser of one thousand feet and any radius required pursuant to any Facility Mortgage then in effect, and (b) with respect to terrorism coverage, one thousand feet (it being agreed that with respect to the Bellagio Hotel & Casino and the Aria Leased Property, the parking garage located at the Bellagio Hotel & Casino would not count towards the calculation of such radius) (each, the “Radius”), the limits of such blanket insurance policy must be sufficient to maintain property and terrorism coverage as set forth in this Article XIII for the Leased Property and any and all other locations combined within the applicable Radius that are covered by such blanket insurance policy calculated on a total insured value basis.”
