Sublessor is the current sublessor and Sublessee is the current sublessee under that certain sublease described on Schedule A hereto (the

 Sublessor has negotiated the terms of a loan of up to five hundred million dollars ($500,000,000) (of which $219,000,000.00 has heretofore been funded and an additional advance of $50,000,000.00 is being

(the “Loan Agreement”) to provide, inter alia, funds with which to pay for the costs of ongoing capital improvement programs for the Demised Premises. 
 NOW, THEREFORE, in consideration of the sum of ten ($10.00) dollars, the mutual promises and covenants herein contained, and for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto, intending to be bound, hereby agree as follows: 
 1. Terms used herein and not
otherwise defined herein have the meanings attributed to them in the Sublease. 
 2. Sublessee consents, as of the date of this
Sixth Modification of Sublease, to an additional draw under the Mortgage Note (as defined in Subdivision (1)(g) of Section 2.01 as set forth in Section 2 of the Third Modification of Sublease) of up to fifty million dollars
($50,000,000.00), which additional draw, together with all draws heretofore made under the Mortgage Note, aggregate to two hundred sixty-nine million dollars ($269,000,000.00). Nothing herein shall affect the terms of that certain Confirmation of
Subordination made by Sublessee in favor of Agent delivered in accordance with the Loan Agreement. 
 3. Sublessee confirms that
pursuant to the Sublease, it is responsible for (i) paying all real estate taxes and similar impositions levied against the Demised Premises; (ii) maintaining, at its cost and expense, the Demised Premises in good condition and repair;
(iii) insuring the Demised Premises and paying all premiums with respect to the insurance; (iv) complying with laws and regulations; (v) keeping the Demised Premises free of mechanics liens and code violations applicable to the use
and occupancy of the Demised Premises; and (vi) performing the acts that would typically be the subject of protective advances by an institutional lender either to cure a default or to preserve the lien of its mortgage and the value of its
security. Sublessee acknowledges that (i) it has received a copy of the Loan Agreement; (ii) it is a party to certain Loan Documents (as defined in the Loan Agreement) and (iii) it shall abide by its obligations thereunder. Nothing
herein shall constitute an acknowledgement by Sublessee that Sublessee is obligated to pay the Debt (as defined in the Loan Agreement). 







 4. Except as herein modified, the Sublease shall be and remain in full force and effect, and
the parties hereby ratify and confirm all of the other terms, covenants and conditions thereof. 
 5. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective legal representatives, successors and assigns.
