RECITALS

     WHEREAS, the Borrower has requested that the Lenders permit the aggregate Commitments to be increased to $575,000,000, extend the Maturity Date, and make other amendments to the Credit Agreement, and the Lenders are willing to make such changes;

     WHEREAS, pursuant to Section 2.4 of the Credit Agreement, the Borrower has requested, and the New Lenders, certain of the existing Lenders and the Administrative Agent have agreed, to increase existing Commitments or provide new Commitments under the Credit Agreement; and

     WHEREAS, each of the New Lenders wishes to be added as a “Lender” under the Credit Agreement;

     NOW, THEREFORE, in consideration of the premises and the agreements, provisions and covenants herein contained, the parties hereto agree as follows:

SECTION 1. AMENDMENTS TO CREDIT AGREEMENT. As of the Amendment Effective Date (as defined in Section 4 hereof), the Credit Agreement is hereby amended as follows:

     1.1 Extension of Maturity Date. The definition of “Maturity Date” in Section 1.1 of the Credit Agreement is restated in its entirety to read as follows:

     “Maturity Date” means May 13, 2014; provided that the Borrower may, at its option (which shall be binding on the Lenders), by written notice to the Administrative Agent (which shall promptly notify each of the Lenders) given at least thirty (30) but no more than sixty (60) days prior to the then Maturity Date, extend the Maturity Date for up to one (1) year (to not later than May 13, 2015) so long as (A) no Default or Event of Default shall have occurred and be continuing on the date of such written notice, (B) each of the representations and warranties made by any Loan Party in or pursuant to the Loan Documents shall be true and correct in all material respects on and as of the date of such

written notice as if made on and as of such date (unless (x) such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall be true and correct in all material respects as of such earlier date or (y) such representations and warranties are qualified as to “materiality”, “Material Adverse Effect” or similar language, in which case such representations and warranties shall be true and correct in all respects taking into account such language), and (C) the Borrower pays an aggregate extension fee equal to 0.25% of the then existing Commitments (to the Administrative Agent for the ratable benefit of the Lenders).”

     1.2 Definition of Restricted Payment. The definition of “Restricted Payment” in Section 1.1 of the Credit Agreement is amended by inserting the words “, but excluding dividends payable solely in additional shares of common stock of the Borrower” at the end of such definition.

     1.3 Increase of Amount of Permitted Incremental Commitments. Section 2.4(a) of the Credit Agreement is amended by deleting the amount “$225,000,000” set forth in each of the fourth and eleventh lines thereof and substituting the amount “$300,000,000” in place thereof.

“(b) Secured Leverage Ratio. Permit the ratio of Secured Indebtedness to Total Asset Value as at the last day of any period of four consecutive fiscal quarters of the Company to exceed 40%.”

     1.5 Deletion of Section 6.13(h). Section 6.13(h) of the Credit Agreement is amended by deleting such section in its entirety and substituting the following in place thereof:

     “(h) [Reserved].”
