Inland Diversified Real Estate Trust, Inc. Announces Definitive Agreement to Sell $503 million of Single Tenant, Net-Leased Properties

-Portfolio sale of 84 single tenant properties for approximately $503 million, which will generate proceeds of approximately $223 million net of debt and closing costs

-With this profitable transaction, Inland Diversified is now positioned as a focused multi-tenant retail REIT as it progresses toward the final stage of a liquidity event

Oak Brook, Ill. – Inland Diversified Real Estate Trust, Inc. (“Inland Diversified”) announced today that it has entered into definitive sale agreements with Realty Income Corporation (NYSE: “O”) to sell 84 single tenant, net-leased properties for approximately $503 million, or approximately $223 million net of debt and closing costs.

“This exciting transaction positions Inland Diversified’s national portfolio of quality multi-tenant retail assets for the final stage of its liquidity event, which a special committee of independent directors continues to pursue,” said Barry Lazarus, president and chief operating officer of Inland Diversified. Mr. Lazarus added, “This sale is an important first step in our overall strategy designed to maximize the value of this portfolio on behalf of stockholders.”

The expected proceeds from these transactions, when combined with cumulative monthly distributions, represent a return to investors of approximately 40 percent, assuming a purchase of shares of Inland Diversified in September 2009. This return is based on the proportion that the equity invested in the assets sold bears to the total equity invested in Inland Diversified.

The transaction is expected to close in several tranches during the first quarter 2014, with the first closing expected in January 2014. Each closing is subject to customary approvals and the completion of certain closing conditions, and it is possible that the timing of the closings may be delayed. Inland Diversified presently intends to make distributions to its stockholders of the net proceeds following each of the closings.
