NON-GAAP FINANCIAL MEASURE DEFINITIONS

JUNE 30, 2007

This document includes certain non-GAAP financial measures that management believes are helpful in understanding our business, as further described below. Our definition and calculation of non-GAAP financial measures may differ from those of other REITs, and therefore, may not be comparable. The non-GAAP measures should not be considered an alternative to net income as an indicator of our performance and should be considered only a supplement to cash flows from operating, investing or financing activities as a measure of liquidity, computed in accordance with GAAP. Funds from Operations (FFO) We present funds from operations, or FFO, because we consider it an important supplemental measure of our operating performance and believe it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, many of which present FFO when reporting their results. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions and extraordinary items, it provides an operating performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities and interest costs, providing perspective not immediately apparent from net income. We compute FFO in accordance with standards established by the Board of Governors of the National Association of Real Estate Investment Trusts, or NAREIT, in its March 1995 White Paper (as amended in November 1999 and April 2002). As defined by NAREIT, FFO represents net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property, plus real estate related depreciation and amortization (excluding amortization of loan origination costs) and after adjustments for unconsolidated partnerships and joint ventures. Our computation may differ from the methodology for calculating FFO utilized by other equity REITs and, accordingly, may not be comparable to such other REITs. Further, FFO does not represent amounts available for management’s discretionary use because of needed capital replacement or expansion, debt service obligations, or other commitments and uncertainties. FFO should not be considered as an alternative to net income (loss) (computed in accordance with GAAP) as an indicator of our financial performance or to cash flow from operating activities (computed in accordance with GAAP) as an indicator of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to pay dividends or make distributions. Adjusted Funds from Operations (AFFO) We present adjusted funds from operations, or AFFO, as a supplemental operating measure because, when compared year over year, it assesses our ability to fund dividend and distribution requirements from our operating activities. We also believe that, as a widely recognized measure of the operations of REITs, AFFO will be used by investors as a basis to assess our ability to fund dividend payments in comparison to other REITs. We calculate AFFO by adding to FFO: (a) amounts received pursuant to master lease agreements on certain properties, which are not included in rental income for GAAP purposes, and (b) non-cash operating revenues and expenses. Other equity REITs may not calculate AFFO in a consistent manner. Accordingly, our AFFO may not be comparable to other equity REITs’ AFFO. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our operations. Earnings before Interest, Taxes, Depreciation and Amortization (E BITDA) and Adjusted EBITDA EBITDA is defined as earnings before interest, taxes, depreciation and amortization. We calculate adjusted EBITDA by adding to EBITDA: (a) minority interests in our operating partnership and (b) dividends payable on our series A preferred stock. Management uses EBITDA and adjusted EBITDA as indicators of our ability to incur and service debt. In addition, we consider EBITDA and adjusted EBITDA to be appropriate supplemental measures of our performance because they eliminate depreciation and interest, which permits investors to view income from operations without the impact of non-cash depreciation or the cost of debt. However, because EBITDA and adjusted EBITDA are calculated before recurring cash charges including interest expense and taxes, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utility is limited. Coverage Ratios We present interest and fixed charge ratios as supplemental liquidity measures. Management uses these ratios as indicators of our financial flexibility to service current interest expense and debt amortization from current cash net operating income. In addition, we believe that these coverage ratios represent common metrics used by securities analysts, investors and other interested parties to evaluate our ability to service fixed cash payments. However, because these ratios are derived from adjusted EBITDA, their utility is limited by the same factors that limit the usefulness of adjusted EBITDA as a liquidity measure. Net Operating Income (NOI) We use net operating income, or NOI, as a performance measure and believe NOI provides useful information to investors regarding our financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level. We compute NOI by adding or subtracting certain items from net income, minority interest in the operating partnership, gains/losses from investment in unconsolidated partnerships, interest expense, interest income, depreciation and amortization, and general and administrative expenses. NOI presented by us may not be comparable to NOI reported by other REITs that define NOI differently. NOI should not be considered as an alternative to net income as an indication of our performance or to cash flows as a measure of liquidity or ability to make distributions.
