a Second Amendment to Lease dated May 11, 2001, and Third Amendment to Lease dated August     , 2010 (the lease, as amended, is collectively referred to herein as the Lease), executed by Owner, as landlord, and

THEREFORE, The parties agree as follows:

the Lease.

1.2 Entire Agreement. This Agreement shall be the whole agreement and only agreement with regard to
the subordination of the Lease to the lien or charge of the Mortgage, and shall supersede and cancel, but only insofar as would affect the priority between the Mortgage and the Lease, any prior agreements as to such subordination, including, without
limitation, those provisions, if any, contained in the Lease which provide for the subordination of the Lease to a deed or deeds of trust, a mortgage or mortgages, a deed or deeds to secure debt or a trust indenture or trust indentures.

Mortgage.

in the Lease to cure such default) on the part of Tenant under the Lease at the time of any foreclosure of the Mortgage, Lender agrees that the leasehold interest of Tenant under the Lease shall not be terminated by reason of such foreclosure, but
rather the Lease shall continue in full force and effect and Lender shall recognize and accept Tenant as tenant under the Lease subject to the provisions of the Lease.

2.2 Attornment. Notwithstanding anything to the contrary contained in the Lease, should title to the leased premises and the landlords interest in the Lease be transferred to Lender or
any other person or entity (New Owner) by, or in-lieu of judicial or non-judicial foreclosure of the Mortgage, Tenant agrees, for the benefit of New Owner and effective immediately and automatically upon the occurrence of any such
transfer, that: (a) Tenant shall pay to New Owner all rental payments required to be made by Tenant pursuant to the terms of the Lease for the remainder of the Lease term; (b) Tenant shall be bound to New Owner in accordance with all of
the provisions of the Lease for the remainder of the Lease term; (c) Tenant hereby attorns to New Owner as its landlord, such attornment to be effective and self-operative without the execution of any further instrument; (d) New Owner
shall not be liable for any default of any prior landlord under the Lease, including, without limitation, Owner, except where such default is continuing at the time New Owner acquires title to the leased premises and New Owner fails to cure same
after receiving notice thereof; (e) New Owner shall not be subject to any offsets or defenses which Tenant may have against any prior landlord under the Lease, including, without limitation, Owner, except where such offsets or defenses arise
out of a default of the prior landlord which is continuing at the time New Owner acquires title to the leased premises and New Owner fails to cure same after receiving notice thereof; and (f) New Owner shall not be liable for any obligations of
landlord arising under the Lease following any subsequent transfer of the title to the leased premises by New Owner.

Recital B.
