Forward Looking Statements

Certain statements in this Form 8-K that are not in the present or past tense or that discuss Kite Realty’s and/or Inland Diversified’s expectations (including any use of the words “anticipate,” “assume,” “believe,” “estimate,” “expect,” “forecast,” “guidance,” “intend,” “may,” “might,” “outlook,” “project”, “should” or similar expressions) are forward-looking statements within the meaning of the federal securities laws and as such are based upon current beliefs as to the outcome and timing of future events. These forward-looking statements, which are based on current expectations, estimates and projections about the industry and markets in which Kite Realty and Inland Diversified operate and beliefs of and assumptions made by their respective management, involve uncertainties that could significantly affect the financial results of Kite Realty, Inland Diversified or the combined company. There can be no assurance that actual future developments affecting Kite Realty, Inland Diversified or the combined company will be those anticipated by Kite Realty or Inland Diversified. Examples of forward-looking statements include projected 2014 fully diluted FFO, share of depreciation and amortization, reported FFO per share, projected net operating income, cap rates, internal rates of return, future dividend payment rates, forecasts of FFO accretion, projected capital improvements, expected sources of financing, expectations as to the timing of closing of acquisitions, dispositions and other potential transactions and descriptions relating to these expectations. These forward-looking statements involve risks and uncertainties (some of which are beyond the control of Kite Realty or Inland Diversified) and are subject to change based upon various factors including, but not limited to, the following risks and uncertainties: changes in the real estate industry and in performance of the financial markets and interest rates; the demand for and market acceptance of either company’s properties for rental purposes; the ability of either company to enter into new leases or renewal leases on favorable terms; the amount and growth of either company’s expenses; tenant financial difficulties and general economic conditions, including interest rates, as well as economic conditions and competition in those areas where either company owns properties; risks associated with joint venture partners; risks associated with the ownership and development of real property; the outcome of claims and litigation involving or affecting either company; the ability to satisfy conditions necessary to close pending transactions and the ability to successfully integrate pending transactions; applicable regulatory changes; risks associated with acquisitions, including the integration of the combined companies’ businesses; risks associated with achieving expected revenue synergies or cost savings; risks associated with the companies’ ability to consummate the Merger and the timing of the closing of the Merger; and other risks and uncertainties detailed from time to time in Kite Realty’s or Inland Diversified’s SEC filings. Should one or more of these risks or uncertainties occur, or should underlying assumptions prove incorrect, the business, financial condition, liquidity, cash flows and financial results of either company could differ materially from

those expressed in the forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made. New risks and uncertainties arise over time, and it is not possible for us to predict the occurrence of those matters or the manner in which they may affect us. Kite Realty does not undertake to update forward-looking statements except as may be required by law.
