An improvement program has been undertaken by Sublessee to maintain the competitive position of the Demised Premises;

A substantial portion of said program is being funded from cash flow from the Demised Premises, a tax result of which is to create “phantom” income for the members of Sublessee;

Sublessor and Sublessee have agreed that a more economic approach to funding the program would be to borrow some portion of the costs thereof.  Sublessor has obtained a commitment from Signature Bank to lend to Sublessor and Empire State Land Associates L.L.C., the current Lessor of the Demised Premises, the sum of thirty-one million five hundred thousand ($31,500,000) dollars; and

Sublessor is willing to make funds available from such borrowing for the improvement program, provided that the rental payable by Sublessee is increased as hereinafter provided.

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 have the meanings attributed to them in the Sublease.

2.

Subdivision 1 of Section 2.01 of the Sublease is hereby modified by adding thereto the following provision:

“(g)

Notwithstanding anything herein set forth to the contrary, the rental payable by Sublessee pursuant to the preceding paragraphs of this subdivision 1 of Section 2.01 shall be increased by the amount of debt service payable each month pursuant to that certain Mortgage Note dated

2

February 25, 2009 made by Lessor and Sublessor to Signature Bank (hereinafter called the “Mortgage Note”) and under any replacement of such Mortgage Note or additional promissory note made by Lessor and/or Sublessor in connection with the refinancing of the indebtededness evidenced by such Mortgage Note, irrespective of any increase in such monthly amount due to any increase in the principal amount thereof or rate of interest payable with respect thereto or as a result of the incorporation of a principal component in such monthly installment of debt service.  Notwithstanding the provisions of the preceding sentence, the rental payable pursuant to this paragraph (g) shall not include principal payable upon the maturity of such Mortgage Note or any such replacement or additional note or any principal component of any monthly debt service installment that is not included therein on a self-amortizing basis.  The principal amount of any proximate or remote refinancing of the Mortgage Note upon which rental under this paragraph (g) is computed shall not exceed the principal amount of the then current indebtedness plus the reasonable costs of refinancing (including, without limitation, origination fees, legal fees, brokerage commissions, recording taxes, costs of appraisals and other customary costs associated with commercial mortgage borrowings).  The amount of any such increase in rental pursuant to this paragraph shall be determined by Sublessor in accordance with the terms hereof and shall be payable on the first day of each month following notice thereof to Sublessee, provided that any such increase shall be retroactive to the first day that interest shall accrue under such Mortgage Note or replacement or additional note.”

3.

Except as herein modified, the Subease shall remain in full force and effect, and the parties hereby ratify and confirm all of the other terms, covenants and conditions thereof.

4.

This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective legal representatives, successors and assigns.

IN WITNESS WHEREOF, the parties hereto have hereunto set their hands as of the day and year first above written.
