Appendix: Non-GAAP Financial Measure Definitions Definition of Funds From Operations (FFO) The Company evaluates performance based on Funds From Operations, which we refer to as FFO, as management believes that FFO represents the most accurate measure of activity and is the basis for distributions paid to equity holders. The Company defines FFO as net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property and acquisition costs of newly acquired properties that are not capitalized, plus depreciation and amortization, including amortization of acquired above and below market lease intangibles and impairment charges on properties or investments in non-consolidated REITs, and after adjustments to exclude equity in income or losses from, and, to include the proportionate share of FFO from, non-consolidated REITs. FFO should not be considered as an alternative to net income (determined in accordance with GAAP), nor as an indicator of the Company’s financial performance, nor as an alternative to cash flows from operating activities (determined in accordance with GAAP), nor as a measure of the Company’s liquidity, nor is it necessarily indicative of sufficient cash flow to fund all of the Company’s needs. Other real estate companies and the National Association of Real Estate Investment Trusts, or NAREIT, may define this term in a different manner. We have included the NAREIT FFO definition in our table and note that other REITs may not define FFO in accordance with the current NAREIT definition or may interpret the current NAREIT definition differently than we do. We believe that in order to facilitate a clear understanding of the results of the Company, FFO should be examined in connection with net income and cash flows from operating, investing and financing activities in the consolidated financial statements. Appendix: Non-GAAP Financial Measure Definitions and Reconciliations to GAAP Net Income

Definition of Adjusted Funds From Operations (AFFO) The Company defines AFFO as the sum of (1) FFO; (2) excluding our proportionate share of FFO and including distributions received, from non-consolidated REITs; (3) excluding the effect of straight-line rent; (4) plus deferred financing costs, (5) less recurring capital expenditures that are generally for (a) maintenance of properties, which we call non-investment capex or are second generation capital expenditures. Second generation costs include re-tenanting space after a tenant vacates, which include tenant improvements and leasing commissions. We exclude development/redevelopment activities, capital expenditures planned at acquisition and costs to reposition a property. We also exclude first generation leasing costs, which are generally to fill vacant space in properties we acquire or were planned for at acquisition. AFFO should not be considered as an alternative to net income (determined in accordance with GAAP), as an indicator of the Company’s financial performance, nor as an alternative to cash flows from operating activities (determined in accordance with GAAP), nor as a measure of the Company’s liquidity, nor is it necessarily indicative of sufficient cash flow to fund all of the Company’s needs. Other real estate companies may define this term in a different manner. We believe that in order to facilitate a clear understanding of the results of the Company, AFFO should be examined in connection with net income and cash flows from operating, investing and financing activities in the consolidated financial statements.

Definition of Earnings before Interest, Taxes, Depreciation and Amortization (EBITDA) and Adjusted EBITDA EBITDA is defined as net income plus interest expense, income tax expense and depreciation and amortization expense. Adjusted EBITDA is defined as EBITDA excluding gains and losses on sales of properties or shares of equity investments or provisions for losses on assets held for sale. EBITDA and Adjusted EBITDA are not intended to represent cash flow for the period, are not presented as an alternative to operating income as an indicator of operating performance, should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP and are not indicative of operating income or cash provided by operating activities as determined under GAAP. EBITDA and Adjusted EBITDA are presented solely as a supplemental disclosure with respect to liquidity because the Company believes it provides useful information regarding the Company's ability to service or incur debt. Because all companies do not calculate EBITDA or Adjusted EBITDA the same way, this presentation may not be comparable to similarly titled measures of other companies. The Company believes that net income is the financial measure calculated and presented in accordance with GAAP that is most directly comparable to EBITDA and Adjusted EBITDA.
