 Exhibit 10.11 
 SIXTH LEASE MODIFICATION AGREEMENT 
 AGREEMENT made as
of October 1, 1987 between 60 EAST 42ND ST.
ASSOCIATES, a co-partnership having its office at 60 East 42nd Street, New York, New York (hereinafter called “Landlord”) and LINCOLN BUILDING ASSOCIATES, a co-partnership, having its office at 60 East 42nd Street, New York, New York (hereinafter called “Tenant”).

 W I T N E S S E T H: 

WHEREAS, the parties entered into an agreement of lease dated October 1, 1958, whereby Landlord leased to
Tenant, and Tenant hired that certain parcel of real property, with the buildings and improvements thereon, known as and by the street numbers 60 East 42nd Street and 301 Madison Avenue, New York, New York, together with the fixtures, chattels and articles of personal
property used in connection with said premises; and 
 WHEREAS, the lease was modified by agreements dated January 1, 1964,
as of January 1, 1977, as of April 1, 1979, as of April 1, 1981 and as of April 1, 1982 (which lease, as so modified, is hereinafter called the “Lease”); and 

WHEREAS, Landlord and Tenant wish to further modify the Lease. 
 NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained, the parties agree that the Lease shall be and is hereby modified in the manner hereinafter set forth: 

1. Paragraph 2A(ii) of the Lease shall be deemed deleted in its entirety and the following substituted in its place and stead:

 “(ii) Commencing October 1, 1987, Tenant covenants to pay, in equal monthly installments of
$94,339.58 each, in advance, on the first day of each month during the term of this Lease, and any renewal term of this Lease, a basic rent (hereinafter called “Basic Rent”) at an annual rate of ONE MILLION, ONE HUNDRED AND THIRTY-TWO
THOUSAND SEVENTY-FIVE DOLLARS AND 00/100 ($1,132,075.00), said amount being equal to the sum of the current mortgage charges plus $24,000; it being understood and agreed that the amount of Basic Rent shall be adjusted upon refinancing of any First
Mortgage (as defined in Paragraph 30), subject to and in accordance with the provisions of Paragraph 30.” 
 2. The parties
confirm that Paragraph 30 of the Lease reads as follows: 
 “30. For the purpose of this Paragraph 30, the
term ‘First Mortgage’ shall mean any first fee mortgage to which this Lease is subordinate under the provisions of Paragraph 13 of this Lease and the term ‘refinancing’ shall include any consolidation, modification, renewal,
extension or replacement of any First Mortgage made subsequent to April 1, 1979. In the event that there shall be one or more refinancings of any First Mortgage, for the period prior to the full liquidation of the Mortgage, the Basic Rent will
be modified to equal the sum of TWENTY-FOUR THOUSAND DOLLARS ($24,000.00) plus an amount equal the product of (A) the new debt service percentage rate under such refinanced First Mortgage multiplied by (B) the principal balance of the
First Mortgage immediately prior to each such refinancing. 

  
 48124.1 








 The following illustrates the intention of the parties hereto as to the computation of the
aforementioned adjustment of the Basic Rent: 
 Assuming a refinancing of the First Mortgage and the principal
balance of the First Mortgage were increased from $12,293,973 to $15,000,000 and the new annual debt service requirements were $1,650,000 or at the rate of 11% of that new principal balance, that portion of the Basic Rent relating to the mortgage
charges would be increased to $1,352,337, 11% of the balance immediately prior to such refinancing. The balance of the charges on the First Mortgage or $297,663 would be paid by Landlord from Additional Rent and Landlord would retain the full net
proceeds of such refinancing. 
 In the event of subsequent refinancings of the First Mortgage, the principal
balance referred to in (B) above, shall be reduced by the amount of mortgage amortization payable from Basic Rent subsequent to the first refinancing of the First Mortgage.” 

3. Except as herein modified, the Lease 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 Sixth Lease Modification Agreement shall be binding upon an inure to the
benefit of the parties hereto and their respective legal representatives, successors and assigns. 
 IN WITNESS WHEREOF, the
parties hereto have duly executed this Agreement as of the day and year first above written.
