Second Quarter 2011 Supplemental Financial Report

Management Statements on Non-GAAP Supplemental Measures

Included in this section are management’s statements regarding certain non-GAAP financial measures provided in this supplemental financial report and, with respect to Funds From Operations (“FFO”), in the Company’s earnings release on July 26, 2011 and the reasons why management believes that these measures provide useful information to investors about the Company’s financial condition and results of operations.

Net Operating Income:

Management believes that Net Operating Income (“NOI”) is a useful supplemental measure of the Company’s operating performance. The Company defines NOI as operating revenues (rental income, tenant reimbursements and other property income) less property and related expenses (property expenses, real estate taxes, provision for bad debts and ground leases). Other real estate investment trusts (“REITs”) may use different methodologies for calculating NOI, and accordingly, the Company’s NOI may not be comparable to other REITs.

Because NOI excludes general and administrative expenses, interest expense, depreciation and amortization, acquisition-related expenses, other nonproperty income and losses, and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, reflects the revenues and expenses directly associated with owning and operating commercial real estate and the impact to operations from trends in occupancy rates, rental rates, and operating costs, providing a perspective on operations not immediately apparent from net income. The Company uses NOI to evaluate its operating performance on a segment basis since NOI allows the Company to evaluate the impact that factors such as occupancy levels, lease structure, rental rates, and tenant base, which vary by segment type, have on the Company’s results, margins and returns. In addition, management believes that NOI provides useful information to the investment community about the Company’s financial and operating performance when compared to other REITs since NOI is generally recognized as a standard measure of performance in the real estate industry.

However, NOI should not be viewed as an alternative measure of the Company’s financial performance since it does not reflect general and administrative expenses, acquisition-related expenses, interest expense, depreciation and amortization costs, other nonproperty income and losses, the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company’s properties, or trends in development and construction activities which are significant economic costs and activities that could materially impact the Company’s results from operations.

Same Store Net Operating Income:

Management believes that Same Store NOI is a useful supplemental measure of the Company’s operating performance. Same Store NOI represents the NOI for the stabilized properties that were operational for two comparable reporting periods. Because Same Store NOI excludes the change in NOI from properties developed, redeveloped, acquired and disposed of, it highlights operating trends such as occupancy levels, rental rates and operating costs on properties that were operational for two comparable periods. Other REITs may use different methodologies for calculating Same Store NOI, and accordingly, the Company’s Same Store NOI may not be comparable to other REITs.

However, Same Store NOI should not be viewed as an alternative measure of the Company’s financial performance since it does not reflect the operations of the Company’s entire portfolio, nor does it reflect the impact of general and administrative expenses, acquisition-related expenses, interest expense, depreciation and amortization costs, other nonproperty income and losses, the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company’s properties, or trends in development and construction activities which are significant economic costs and activities that could materially impact the Company’s results from operations.

Management Statements on Non-GAAP Supplemental Measures

EBITDA:

Management believes that earnings before interest expense, depreciation and amortization, gain/loss on early extinguishment of debt, net gains and losses on disposition of discontinued operations, net income attributable to noncontrolling interests, preferred dividends and distributions, and impairment losses (“EBITDA”) is a useful supplemental measure of the Company’s operating performance. When considered with other GAAP measures and FFO, management believes EBITDA gives the investment community a more complete understanding of the Company’s operating results, including the impact of general and administrative expenses and acquisition-related expenses, before the impact of investing and financing transactions and facilitates comparisons with competitors. Management also believes it is appropriate to present EBITDA as it is used in several of the Company’s financial covenants for both its secured and unsecured debt. However, EBITDA should not be viewed as an alternative measure of the Company’s operating performance since it excludes financing costs as well as depreciation and amortization costs which are significant economic costs that could materially impact the Company’s results of operations and liquidity. Other REITs may use different methodologies for calculating EBITDA and, accordingly, the Company’s EBITDA may not be comparable to other REITs.

Funds From Operations:

The Company calculates FFO in accordance with the White Paper on FFO approved by the Board of Governors of NAREIT. The White Paper defines FFO as net income or loss calculated in accordance with GAAP, excluding extraordinary items, as defined by GAAP, and gains and losses from sales of depreciable operating property, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs and depreciation of non-real estate assets), and after adjustment for unconsolidated partnerships and joint ventures.

Management believes that FFO is a useful supplemental measure of the Company’s operating performance. The exclusion from FFO of gains and losses from the sale of operating real estate assets allows investors and analysts to readily identify the operating results of the assets that form the core of the Company’s activity and assists in comparing those operating results between periods. Also, because FFO is generally recognized as the industry standard for reporting the operations of REITs, it facilitates comparisons of operating performance to other REITs. However, other REITs may use different methodologies to calculate FFO, and accordingly, the Company’s FFO may not be comparable to all other REITs.

Implicit in historical cost accounting for real estate assets in accordance with GAAP is the assumption that the value of real estate assets diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, many industry investors and analysts have considered presentations of operating results for real estate companies using historical cost accounting alone to be insufficient. Because FFO excludes depreciation and amortization of real estate assets, management believes that FFO along with the required GAAP presentations provides a more complete measurement of the Company’s performance relative to its competitors and a more appropriate basis on which to make decisions involving operating, financing and investing activities than the required GAAP presentations alone would provide.

However, FFO should not be viewed as an alternative measure of the Company’s operating performance since it does not reflect either depreciation and amortization costs or the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company’s properties, which are significant economic costs and could materially impact the Company’s results from operations.

Funds Available for Distribution:

Management believes that Funds Available for Distribution (“FAD”) is a useful supplemental measure of the Company’s liquidity. The Company computes FAD by adding to FFO the noncash amortization of deferred financing costs, debt discounts and share-based compensation awards, adjustment to GAAP gain/loss on early extinguishment of debt, amortization of above (below) market rents for acquisition properties and contractual cash rents received in advance of revenue recognition, then subtracting recurring tenant improvements, leasing commissions and capital expenditures, and eliminating the net effect of straight-line rents, amortization of deferred revenue related to tenant improvements and cash received prior to revenue recognition. FAD provides an additional perspective on the Company’s ability to fund cash needs and make distributions to stockholders by adjusting FFO for the impact of certain cash and noncash items, as well as adjusting FFO for recurring capital expenditures and leasing costs. Management also believes that FAD provides useful information to the investment community about the Company’s financial position as compared to other REITs since FAD is a liquidity measure used by other REITs. However, other REITs may use different methodologies for calculating FAD and, accordingly, the Company’s FAD may not be comparable to other REITs.
