Definitions / Discussion of Non-GAAP Financial Measures:

Funds from Operations (FFO): We calculate FFO before non-controlling interest in accordance with the standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of depreciable operating property, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization, gains and losses from property dispositions, other than temporary impairments of unconsolidated real estate entities, and impairment on our investment in real estate, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of performance used by other REITs, FFO may be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effects and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. Other equity REITs may not calculate or interpret FFO in accordance with the NAREIT definition as we do, and, accordingly, our FFO may not be comparable to such other REITs’ FFO. FFO should not be used as a measure of our liquidity, and is not indicative of funds available for our cash needs, including our ability to pay dividends. A reconciliation of FFO before noncontrolling interest to net income, the nearest GAAP equivalent, is set forth below.

NOI: Includes the revenue and expense directly attributable to our real estate properties calculated in accordance with GAAP. Calculated as total revenue from real estate operations including i) rental revenues ii) tenant reimbursements, and iii) other income less property expenses (before interest expense, depreciation and amortization). We use NOI as a supplemental performance measure because, in excluding real estate depreciation and amortization expense and gains (or losses) from property

dispositions, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that NOI will be useful to investors as a basis to compare our operating performance with that of other REITs. However, because NOI excludes depreciation and amortization expense and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties (all of which have real economic effect and could materially impact our results from operations), the utility of NOI as a measure of our performance is limited. Other equity REITs may not calculate NOI in a similar manner and, accordingly, our NOI may not be comparable to such other REITs’ NOI. Accordingly, NOI should be considered only as a supplement to net income as a measure of our performance. NOI should not be used as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs.

NOI should not be used as a substitute for cash flow from operating activities in accordance with GAAP. We use NOI to help evaluate the performance of the Company as a whole, as well as the performance of our Same Property Portfolio. A calculation of NOI for our Same Property Portfolio, as well as a reconciliation of NOI for our Same Property Portfolio to net income for our Same Property Portfolio, is set forth below.

Cash NOI: Cash basis NOI is a non-GAAP measure, which we calculate by adding or subtracting from NOI i) fair value lease revenue and ii) straight-line rent adjustment. We use Cash NOI, together with NOI, as a supplemental performance measure. Cash NOI should not be used as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs. Cash NOI should not be used as a substitute for cash flow from operating activities computed in accordance with GAAP. We use Cash NOI to help evaluate the performance of the Company as a whole, as well as the performance of our Same Property Portfolio. A calculation of Cash NOI for our Same Property Portfolio, as well as a reconciliation of Cash NOI for our Same Property Portfolio to net income for our Same Property Portfolio, is set forth below.

Same Property Portfolio: Determined independently for each period presented. Comparable properties must have been owned for the entire current and prior periods presented. The Company’s computation of same property performance may not be comparable to other real estate companies.
