RECITALS:

A.        Landlord, as landlord, and certain affiliates of Guarantor, as tenants, are parties to certain Lease Agreements, as amended, that are more particularly described in Schedule A attached hereto (the “Leases”).

B.        As a material inducement for Landlord to enter into the Leases, Guarantor executed certain corresponding Guaranty and Subordination Agreements (collectively referred to herein as the “Guaranties” or each individually as the “Guaranty”), also described on Schedule A, pursuant to which Guarantor guaranteed performance of all obligations of Tenants under the Leases, including but not limited to payment of rent and all other payments required under each Lease, for the benefit of Landlord.

C.        In each Guaranty, there are certain representations and warranties that the Guarantor makes to the Landlord. The Guarantor requested, and the Landlord agreed to amend the Guaranties to make certain modifications to certain financial covenants contained therein, upon the terms and conditions and as more particularly set forth herein below.
