 NOW, THEREFORE, in consideration of the foregoing, and the various agreements set forth herein below, the parties hereto agree as follows:

 ARTICLE 1 
 DISCOUNTED PAYOFF; DEPOSIT 
 1.1 Discounted Payoff. Borrower agrees
to pay to Lender an amount equal to $25,000,000.00 (the “Discounted Payoff Amount”) in cash by wire transfer of immediately available funds to the account specified on Schedule 1 attached hereto prior to 5:00 pm (New

  

 1 








 
York City time) on November 30, 2009 (the “Outside Payoff Date”), subject to Section 1.3 hereof. Provided that each of the conditions set forth in
Section 2.1 hereof have been satisfied, Lender agrees to accept the Discounted Payoff Amount in full and complete satisfaction of the Loans. Upon acceptance of the Discounted Payoff Amount by Lender in accordance with the terms hereof,
the obligations of all Borrower Parties under the Loan Documents and Junior A Mezzanine Loan Documents shall be deemed satisfied and released as if, and to extent, such obligations are satisfied and released upon payment in full of all amounts due
under the Loans, subject only to Section 3.1 hereof. 
 1.2 Deposit. 
 (a) Prior to 5:00 pm (New York City time) on October 16, 2009, Borrower shall deposit with Lender an amount equal to $6,000,000.00 (the
“Deposit”) in cash by wire transfer of immediately available funds to the account specified on Schedule 1 attached hereto. Provided that each of the conditions set forth in Section 2.1 have been satisfied prior to
the Outside Payoff Date (as the same may be extended pursuant to Section 1.3 hereof), the amount of the Deposit will be credited toward the Discounted Payoff Amount. If Borrower fails to satisfy each of the conditions set forth in
Section 2.1 prior to the Outside Payoff Date (as the same may be extended pursuant to Section 1.3 hereof), then (i) Lender shall be entitled to retain a portion of the Deposit equal to $1,000,000 (as the same may be
increased pursuant to Section 1.3 hereof, the “Liquidated Damages Payment”) as liquidated damages for Borrower’s breach of the terms of this Agreement, (ii) the remainder of the Deposit ($5,000,000) shall be applied
by Lender to the Loans on the Outside Payment Date (as the same may be extended pursuant to Section 1.3 hereof) in the following order: first, to any accrued and unpaid interest on the Junior Mezz A Loan; second, to the
outstanding principal amount of the Junior Mezz A Loan; third, to any accrued and unpaid interest on the Senior Mezz Loan; and fourth, to the outstanding principal amount of the Senior Mezz Loan, and (iii) the provisions of
Section 2.3 hereof shall apply. In such event, Lender shall have no obligation to treat the Liquidated Damages Payment as a partial prepayment of the Loans and no portion of the Liquidated Damages Payment shall be applied to the
principal amount of the Loans or any other amounts owed to Lender under the Loan Documents and/or the Junior A Mezzanine Loan Documents. THE PARTIES AGREE THAT LENDER’S ACTUAL DAMAGES IN THE EVENT OF A FAILURE BY BORROWER TO PAY THE DISCOUNTED
PAYOFF AMOUNT IN ACCORDANCE WITH THE TERMS HEREOF WOULD BE EXTREMELY DIFFICULT OR IMPRACTICABLE TO DETERMINE. AFTER NEGOTIATION, THE PARTIES HAVE AGREED THAT, CONSIDERING ALL THE CIRCUMSTANCES EXISTING ON THE DATE OF THIS AGREEMENT, THE AMOUNT OF
THE LIQUIDATED DAMAGES PAYMENT IS A REASONABLE ESTIMATE OF THE DAMAGES THAT LENDER WOULD INCUR IN SUCH EVENT. 
 (b)
Notwithstanding Section 1.2(a), if prior to 5:00 pm (New York City time) on October 30, 2009, Borrower informs Lender by written notice that it has elected not to pay the Discounted Payoff Amount in accordance with the terms hereof,
then Lender shall (i) retain the Liquidated Damages Payment as liquidated damages hereunder and (ii) return the remainder of the Deposit to Borrower. In such event, (a) Lender’s agreement to accept the Discounted Payoff Amount
shall be deemed terminated and of no further force or effect, (b) neither Borrower nor any other party shall be entitled to a discounted payoff of the Loans, (c) Lender shall have no obligation to treat the Liquidated Damages Payment as a
partial prepayment of the Loans and no portion of the Liquidated

  

 2 








 
Damages Payment shall be applied to the principal amount of the Loans or any other amounts owed to Lender under the Loan Documents and/or the Junior A Mezzanine Loan Documents and (d) the
Loan Documents and the Junior Mezzanine A Loan Documents shall remain in full force and effect and continue to control the relationship between the parties. No portion of the Deposit or Additional Deposit (defined below) shall be refundable to
Borrower after 5:00 pm (New York City time) on October 30, 2009. 
 1.3 Extension of Outside Payoff Date. Borrower
shall have the one-time right to extend the Outside Payoff Date to 5:00 pm (New York City time) on December 29, 2009, provided that (a) Borrower shall not be in default of its obligations hereunder and no Event of Default shall have
occurred and be continuing under any of the Loan Documents, the Junior A Mezzanine Loan Documents or the Senior Loan Documents, (b) Borrower shall have provided Lender with written notice of its election to so extend the Outside Payoff Date no
later than 5:00 pm (New York City time) on November 16, 2009, and (c) Borrower shall have deposited with Lender an amount equal to $7,000,000 (the “Additional Deposit”) in cash by wire transfer of immediately available
funds to the account specified on Schedule 1 attached hereto no later than 5:00 PM (New York City time) on November 30, 2009. Once made, the Additional Deposit shall be deemed to constitute a portion of the Deposit hereunder and shall be
applied in accordance with the terms hereof applicable to the Deposit. If, after the making of the Additional Deposit, Borrower fails to satisfy each of the conditions set forth in Section 2.1 prior to the Outside Payoff Date, then
(i) the Liquidated Damages Payment shall be increased to $2,000,000 and Lender shall be entitled to retain such amount as liquidated damages for Borrower’s breach of the terms of this Agreement, (ii) the remaining amount of the
Deposit ($11,000,000) shall be applied by Lender to the Loans on the Outside Payment Date (as extended pursuant to this Section 1.3) in the following order: first, to any accrued and unpaid interest on the Junior Mezz A Loan;
second, to the outstanding principal amount of the Junior Mezz A Loan; third, to any accrued and unpaid interest on the Senior Mezz Loan; and fourth, to the outstanding principal amount of the Senior Mezz Loan, and
(iii) the provisions of Section 2.3 hereof shall apply.

(ii) such loan sale documents shall be in forms acceptable to Lender without any representation or warranties with respect to the Loans whatsoever, other than that Lender is the sole holder of the Loans and has not pledged or encumbered the
Loans, and (iii) the sale of the Loans shall be permitted under the terms of the Intercreditor Agreement and Sponsor shall obtain, prior to the Outside Payoff Date (as the same may be extended pursuant to Section 1.3 hereof), all
consents or other approvals required in order to consummate the sale of the Loans, including, without limitation, any consent or approval required under that certain Intercreditor Agreement, dated July 31, 2003, among Lender, Junior B Mezzanine
Lender and Senior Lender. If Lender and Sponsor are unable to agree on the form of the loan sale documents or, for any other reason the sale of the Loans cannot be consummated prior to the Outside Payoff Date (as the same may be extended pursuant to
Section 1.3 hereof), then Borrower shall remain obligated to pay the Discounted Payoff Amount in accordance with the terms hereof. In the event the

  

 11 








 
transaction is structured as a sale of the Loans, notwithstanding Section 5.4, Sponsor will have the right to assign its rights hereunder to a newly formed entity or entities to enter
