WHEREAS, the parties hereto have determined that it is in the best interests of the parties to amend certain terms of the Equity Distribution Agreement.

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

1.The third paragraph of Section 1 of the Equity Distribution Agreement is hereby amended and restated in its entirety to read as follows:

“The Company and the Operating Partnership have also entered into five (5) separate equity distribution agreements (each an “Alternative Distribution Agreement” and, collectively, the “Alternative Distribution Agreements”), with BMO Capital Markets Corp., JMP Securities LLC, Ladenburg Thalmann & Co. Inc., Robert W. Baird & Co. Incorporated, and Wunderlich Securities, Inc., respectively (each, an “Alternative Placement Agent” and together with Wells, the “Placement Agents”). Each of the Alternative Distribution Agreements is dated June 19, 2013 other than the Alternative Distribution Agreement with Robert W. Baird & Co. Incorporated, which is dated August 14, 2013. The aggregate offering price of the Securities that may be sold pursuant to this Agreement and the Alternative Distribution Agreements shall not exceed the Maximum Amount.
