R E C I T A L S

A.            Borrower, Guarantor, Administrative Agent and the other Lenders have entered into an Fifth Amended and Restated Revolving Credit Agreement dated as of January 25, 2006 (as amended, the “Credit Agreement”).  All capitalized terms used herein and not otherwise defined shall have the meanings given to them in the Credit Agreement.

B.            Pursuant to the terms of the Credit Agreement, the Lenders initially agreed to provide Borrower with a revolving credit facility in an aggregate principal amount of up to $1,000,000,000.  The Borrower, Guarantor, the Administrative Agent and the Lenders now desire to amend the Credit Agreement in order to, among other things (i) increase the Aggregate Commitment to $1,300,000,000 in accordance with Section 2.1 of the Credit Agreement; and (ii) make certain other modifications to the terms of the Credit Agreement.

NOW, THEREFORE, in consideration of the foregoing Recitals and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

AGREEMENTS

1.             The foregoing Recitals to this Amendment hereby are incorporated into and made part of this Amendment.

2.             From and after the Effective Date (as hereinafter defined) the Commitments of each Lender shall each be the amount shown next to their respective signatures on the signature pages of this Amendment.

3.             From and after the Effective Date, the Aggregate Commitment shall equal One Billion Three Hundred Million Dollars ($1,300,000,000).

4.             The parties hereto acknowledge and agree that Wachovia has been designated as Joint Lead Arranger of the Facility together with J.P. Morgan Securities, Inc.

5.             Section 2.4 of the Credit Agreement is hereby amended and restated to read as follows:

Applicable Margins.  The ABR Applicable Margin and the LIBOR Applicable Margin to be used in calculating the interest rate applicable to different Types of Advances shall vary from time to time in accordance with the long-term unsecured debt ratings of the Borrower as set forth

in the table attached as Exhibit A.  In the event that a rating agency shall discontinue its ratings of the REIT industry or the Borrower, a mutually agreeable substitute rating agency may be selected by the Required Lenders and the Borrower.

If a rating agency downgrade or discontinuance results in an increase in the ABR Applicable Margin, the LIBOR Applicable Margin or Facility Fee Rate and if such downgrade or discontinuance is reversed and the affected Applicable Margin is restored within ninety (90) days thereafter, at the Borrower’s request, the Borrower shall receive a credit against interest next due the Lenders equal to interest accrued from time to time during such period of downgrade or discontinuance and actually paid by the Borrower on the Advances at the differential between such Applicable Margins, and the differential of the Facility Fees paid during such period of downgrade.

If a rating agency upgrade results in a decrease in the ABR Applicable Margin, LIBOR Applicable Margin or Facility Fee Rate and if such upgrade is reversed and the affected Applicable Margin is restored within ninety (90) days thereafter, Borrower shall be required to pay an amount to the Lenders equal to the interest differential on the Advances and the differential on the Facility Fees during such period of upgrade.

6.             Section 7.20 (i) of the Credit Agreement is hereby amended and restated to read as follows:

“the ratio of Adjusted EBITDA to Fixed Charges to be less than 1.50 to 1.0 for the preceding 12 full calendar months throughout the remaining term of the Facility;”

7.             Section 7.20 (iii) of the Credit Agreement is hereby amended and restated to read as follows:

“the ratio obtained by dividing: (a) the Property Operating Income from all Unencumbered Assets by (b) interest on Consolidated Unsecured Indebtedness to be less than 1.75 to 1.0 for the quarter then ended.”

8.             Section 7.25 of the Credit Agreement is hereby amended and restated to read as follows:

Notice of Rating Change.  The Borrower shall notify the Administrative Agent promptly if there is any change in the long term unsecured debt rating of the Borrower from Moody’s or S&P.

9.             Exhibit A attached to the Credit Agreement is hereby replaced with Exhibit A attached to this Amendment.

10.           Borrower and Guarantor hereby represent and warrant that:

(a)           no Default or Unmatured Default exists under the Loan Documents;

(b)           the Loan Documents are in full force and effect and Borrower and Guarantor have no defenses or offsets to, or claims or counterclaims relating to, their obligations under the Loan Documents;

2

(c)           no changes have been made to the organizational documents of the Borrower or Guarantor since the date of the Credit Agreement unless such changes have been previously provided to Administrative Agent;

(d)           there has been no material adverse change in the financial condition of  Borrower or the Guarantor since June 30, 2007; and

(e)           Borrower and Guarantor have full power and authority to execute this Amendment.

11.           The “Effective Date” shall be the date on which this Amendment shall have been executed by Borrower, General Partner, Administrative Agent, and the Required Lenders (including each Lender whose commitment has been increased), and all fees due to approving lenders, and the fees and expenses of the Arrangers have been paid.

12.           As expressly modified as provided herein, the Credit Agreement shall continue in full force and effect, and Guarantor reaffirms all of its obligations under the Guaranty.

13.           This Amendment may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this Amendment by signing any such counterpart.  This Amendment shall be construed in accordance with the internal laws (and not the law of conflicts) of the State of Illinois, but giving effect to federal laws applicable to national banks.

For the purposes of this Schedule, the following terms have the following meanings, subject to the final paragraph of this Schedule:

“Level I Rating” means, for the applicable rating agency:  Borrower’s Moody’s Rating is A3 or better; Borrower’s S&P Rating is A- or better.

“Level II Rating” means, for the applicable rating agency: the Borrower’s Moody’s Rating is Baa1 or better; Borrower’s S&P Rating is BBB+ or better.

“Level IV Rating” means, for the applicable rating agency: the Borrower’s Moody’s Rating is Baa3 or better; Borrower’s S&P Rating is BBB- or better.

“Level V Rating” exists at any date if, on such date, the Borrower has not qualified for Level I Rating, Level II Rating, Level III Rating, or Level IV Rating.

“Moody’s Rating” means, at any time, the rating issued by Moody’s Investors Service, Inc. and then in effect with respect to the Borrower’s senior unsecured long-term debt securities without third-party credit enhancement.

“Rating” means Level I Rating, Level II Rating, Level III Rating, Level IV Rating, or Level V Rating.

“S&P Rating” means, at any time, the rating issued by Standard and Poor’s, and then in effect with respect to the Borrower’s senior unsecured long-term debt securities without third-party credit enhancement.

A-1

The Applicable Margin and Applicable Fee Rate shall be determined in accordance with the foregoing table based on the Borrower’s Rating as determined from its then-current Moody’s and S&P Ratings.

In the event that the Ratings of Moody’s and S&P do not match, then the higher of the two Ratings shall determine pricing; provided, however, that if the two Ratings are two gradations apart, then the rating that is between the two differing Ratings shall determine pricing.

The credit rating in effect on any date for the purposes of this Schedule is that in effect at the close of business on such date.  If at any time the Borrower has no Moody’s Rating and no S&P Rating, then Level V Rating shall exist.
