Forward-Looking Statements This presentation contains forward-looking statements, including discussion and analysis of the financial condition of us and our subsidiaries and other matters. These forward-looking statements are not historical facts but are the intent, belief or current expectations of our management based on their knowledge and understanding of our business and industry. Words such as “may,” “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “would,” “could,” “should” and variations of these words and similar expressions are intended to identify forward-looking statements. We intend that such forward-looking statements be subject to the safe harbor provisions created by Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control, are difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements. Forward-looking statements that were true at the time made may ultimately prove to be incorrect or false. We caution you not to place undue reliance on forward-looking statements, which reflect our management’s view only as of the date of this presentation. We undertake no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes to future operating results.

Forward-Looking Statements Factors that could cause actual results to differ materially from any forward-looking statements made in the presentation include but are not limited to: market and economic challenges experienced by the U.S. economy or real estate industry as a whole and the local economic conditions in the markets in which our properties are located; our ability to renew expiring leases and lease vacant spaces at favorable rates or at all; the inability of tenants to continue paying their rent obligations due to bankruptcy, insolvency or a general downturn in their business; the availability of cash flow from operating activities to fund distributions and capital expenditures; our ability to raise capital in the future by issuing additional equity or debt securities, selling our assets or otherwise to fund our future capital needs; our ability to strategically acquire or dispose of assets on favorable terms; our level of debt and the terms and limitations imposed on us by our debt agreements; our ability to retain our executive officers and other key personnel; conflicts of interest and competing demands faced by certain of our directors; limitations on our ability to terminate our property management agreement and certain services under our administrative services agreement; unfavorable changes in laws or regulations impacting our business or our assets; and factors that could affect our ability to qualify as a real estate investment trust. The forward-looking statements should be read in light of these and other risk factors identified in the “Risk Factors” section of our 2013 Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the Securities and Exchange Commission.
