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

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

(a)By deleting the words “RBC CAPITAL MARKETS*, AS SOLE LEAD ARRANGER AND SOLE BOOK MANAGER” appearing on the cover page of the Loan Agreement and replacing them with “RBC CAPITAL MARKETS* AND SUNTRUST ROBINSON HUMPHREY, INC., AS JOINT LEAD ARRANGERS AND JOINT BOOK MANAGERS”.

(b)By deleting the words “RBC CAPITAL MARKETS, AS SYNDICATION AGENT” appearing on the cover page of the Loan Agreement and replacing them with “SUNTRUST BANK, AS SYNDICATION AGENT”.

(e)By deleting in their entirety the definitions of “Applicable Margin”, “Arranger” and “Maturity Date” appearing in §1.1 of the Loan Agreement, and inserting in lieu thereof the following:

“Applicable Margin. (a) On any date, the Applicable Margin for LIBOR Rate Loans and Base Rate Loans shall be a percentage per annum as set forth below based on the ratio of the Consolidated Total Indebtedness to the Borrower’s Gross Asset Value:

The initial Applicable Margin as of July 21, 2014 shall be at Pricing Level 1. At such time as this subparagraph (a) is applicable, the Applicable Margin for each Base Rate Loan shall be determined by reference to the ratio of Consolidated Total Indebtedness to Gross Asset Value in effect from time to time, and the Applicable Margin for any Interest Period for all LIBOR Rate Loans comprising part of the same borrowing shall be determined by reference to the ratio of Consolidated Total Indebtedness to Gross Asset Value in effect on the first (1st) day of such Interest Period. The Applicable Margin shall not be adjusted based upon such ratio, if at all, until the first (1st) day of the first (1st) month following the delivery by REIT to the Agent of the Compliance Certificate after the end of a calendar quarter. In the event that REIT shall fail to deliver to the Agent a quarterly Compliance Certificate on or before the date required by §7.4(c), then without limiting any other rights of the Agent and the Lenders under this Agreement, the Applicable Margin for Loans shall be at Pricing Level 5 until such failure is cured within any applicable cure period, or waived in writing by the Required Lenders in which event the Applicable Margin shall adjust, if necessary, on the first (1st) day of the first (1st) month following receipt of such Compliance Certificate.

(b)    From and after the date that Agent first receives written notice from REIT or Borrower that Borrower has first obtained an Investment Grade Rating and the Borrower delivers a written notice to Agent irrevocably electing to have the Applicable Margin determined pursuant to this subparagraph (b), the Applicable Margin shall mean, as of any date of determination, a percentage per annum determined by reference to the Credit Rating Level as set forth below:

At such time as this subparagraph (b) is applicable, the Applicable Margin for each Base Rate Loan shall be determined by reference to the Credit Rating Level in effect from time to time, and the Applicable Margin for any Interest Period for all LIBOR Rate Loans comprising part of the same borrowing shall be determined by reference to the Credit Rating Level in effect on the first day of such Interest Period; provided, however that no change in the Applicable Margin resulting from the application of the Credit Rating Levels or a change in the Credit Rating Level shall be effective until three (3) Business Days after the date on which the Agent receives written notice of the application of the Credit Rating Levels and Borrower’s irrevocable election to have the Applicable Margin determined pursuant to this subparagraph (b) or a change in such Credit Rating Level. From and after the first date that the Applicable Margin is based on Borrower’s Investment Grade Rating pursuant to this subparagraph (b), the Applicable Margin shall no longer be calculated by reference to the ratio of Consolidated Total Indebtedness to Gross Asset Value (provided that any accrued interest payable at the Applicable Margin determined by reference to the ratio of Consolidated Total Indebtedness to Gross Asset Value prior to such date shall be payable as provided in §2.6).”

“Arrangers. RBC Capital Markets and SunTrust Robinson Humphrey, Inc. or any successor of either of them.”

“Maturity Date. July 21, 2019, or such earlier date on which the Loan shall become due and payable pursuant to the terms hereof.”

(f)All references in the Loan Agreement to “Arranger” shall be replaced with “Arrangers” (other than in the Schedules to the Loan Agreement).

(g)By deleting in its entirety Schedule 1.1 of the Credit Agreement and inserting in lieu thereof Schedule 1.1 attached to this Amendment.

(b)By its signature below, each Subject Lender hereby agrees to perform all obligations with respect to its respective Commitment as set forth in this Amendment, which obligations shall include, but shall not be limited to, the obligation to indemnify the Agent as provided in the Loan Agreement.

(c)On the effective date of this Amendment, (i) the outstanding principal balance of the Advances prior to the effectiveness of this Amendment shall be reallocated among the Lenders such that the outstanding principal amount of the Advances owed to each Lender shall be equal to such Lender’s Commitment (as in effect after the effectiveness of this Amendment), and (ii) those Lenders whose Commitment is increasing shall advance the funds to the Agent and the funds so advanced shall be distributed among the Lenders whose Commitment is decreasing or is unchanged as necessary to accomplish the required reallocation of the outstanding Advances.
