NOW, THEREFORE, for and in consideration of the sum of TEN and NO/100 DOLLARS ($10.00), and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto do hereby covenant and agree as follows:

1.Definitions. All the terms used herein which are not otherwise defined herein shall have the meanings set forth in the Credit Agreement.

2.Modifications of the Credit Agreement. Borrower, the Lenders and Agent do hereby modify and amend the Credit Agreement as follows:

(a)By deleting §6.15 of the Credit Agreement in its entirety and replacing it with the following:

“§6.15    Certain Transactions. Except as disclosed on Schedule 6.15 hereto or as otherwise permitted pursuant to §8.13, none of the partners, officers, trustees, managers, members, directors, or employees of Borrower, the Guarantors or any of their respective Subsidiaries is, a party to any transaction with Borrower, any Guarantor or any of their respective Subsidiaries or Affiliates (other than for services as partners, managers, members, employees, officers and directors), including any agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any partner, officer, trustee, director or such employee or, to the knowledge of the Borrower, any corporation, partnership, trust or other entity in which any partner, officer, trustee, director, or any such employee has a substantial interest or is an officer, director, trustee or partner, which are on terms less favorable to the Borrower, any Guarantor or any of their respective Subsidiaries than those that would be obtained in a comparable arms-length transaction.”

(b)By deleting the words “a merger of a Person with a Subsidiary of the Borrower (other than a Subsidiary which is a Subsidiary Guarantor that directly or indirectly owns an Unencumbered Asset)” appearing in clause (v) of §8.4 of the Credit Agreement, and replacing such words with the following:

“a merger of a Person with (x) Borrower (so long as Borrower is the surviving entity) or (y) a Subsidiary of the Borrower (other than a Subsidiary which is a Subsidiary Guarantor or a Subsidiary that in either case directly or indirectly owns an Unencumbered Property)”

(c)By inserting the following sentence at the end of §8.7(a) of the Credit Agreement:

“In addition to the foregoing, provided that no Default or Event of Default has occurred and is continuing and no Default or Event of Default would occur as a result thereof, Borrower may pay Distributions to REIT and the other partners, members or other owners of Borrower, which Distributions, in the case of Distributions received by the REIT, shall be used solely by REIT to repurchase Equity Interests of REIT, provided that the aggregate amount of (x) such Distributions to REIT and the other partners, members or other owners of Borrower shall not exceed $80,000,000.00 in any calendar year and (y) such repurchases by REIT with the proceeds of such Distributions received by it pursuant to this sentence shall not exceed $80,000,000.00 in any calendar year. Borrower shall report the amount of such Distributions (and any related repurchases of the Equity Interests of REIT) in the next Compliance Certificate delivered hereunder following such Distributions.”
