(1)We compute FFO as shown in the calculations above.  Our calculations of FFO differ from the National Association of Real Estate Investment Trusts, or NAREIT, definition because we add loss on early extinguishment of debt unless settled in cash.  We consider FFO to be an appropriate measure of performance for a REIT, along with net income and cash flow from operating, investing and financing activities.  We believe that FFO provides useful information to investors because by excluding the effects of certain historical amounts, such as depreciation expense and gains or losses on sales of depreciated operating properties, FFO can facilitate a comparison of operating performance among REITs.  FFO does not represent cash generated by operating activities in accordance with generally accepted accounting principles, or GAAP, and should not be considered an alternative to net income or cash flow from operating activities as a measure of financial performance or liquidity.  FFO is one important factor considered by our Board of Trustees in determining the amount of distributions to shareholders.  Other important factors include, but are not limited to, requirements to maintain our status as a REIT, limitations in our revolving credit facility and public debt covenants, the availability of debt and equity capital to us and our expectations of future capital requirements and operating performance.

(2)At September 30, 2007, we had 15,180 series D preferred shares that were convertible into 29,193 common shares.  The effect of our series D convertible preferred shares on income from continuing operations and net income available for common shareholders per share is anti-dilutive to income but dilutive to FFO for the quarter and nine months ended September 30, 2007.  Set forth below is the calculation of diluted net income available for common shareholders, diluted FFO available for common shareholders and diluted weighted average common shares outstanding.

CORPORATE INFORMATION

HRPT Properties Trust

Supplemental Operating and Financial Data

September 30, 2007

COMPANY PROFILE

The Company:

HRPT Properties Trust, or HRPT, is a real estate investment trust, or REIT, which primarily owns office buildings located throughout the United States.  The majority of our properties are commercial office buildings located in central business districts, or CBD, and suburban areas of major metropolitan markets.  At September 30, 2007, we also owned approximately 17 million square feet of leased industrial and commercial lands in Oahu, Hawaii.  We have large concentrations of properties leased to the U.S. Government and medical related tenants.  We have been investment grade rated since 1994 and we are included in a number of financial indices, including the Russell 1000^®, the MSCI US REIT Index, the S&P REIT Composite Index and the FTSE NAREIT Composite Index.

Strategy:

Our primary business strategy is to efficiently operate our properties to maintain high occupancies, at market rents, with strong credit quality tenants.  We attempt to maintain an investment portfolio that is balanced between “security” and “growth”.  The security part of our portfolio includes properties that are long term leased or leased to tenants we believe are likely to renew their occupancy, such as government agencies, tenants in medical related industries and our leased lands in Hawaii.  The growth part of our portfolio includes our multi-tenant commercial office buildings, which we believe may generate higher rents and appreciate in value in the future because of their physical qualities and locations.  Although we sometimes sell properties, we consider ourselves to be a long term investor and are more interested in the long term earnings potential of our properties than selling properties for short term gains.  We currently do not have any investments in joint venture or off balance sheet entities.  We generally do not undertake speculative development, but we will sometimes do a build to suit development project.

Management:

HRPT is managed by Reit Management & Research LLC, or RMR.  RMR was founded in 1986 to manage public investments in real estate.  As of September 30, 2007, RMR managed one of the largest portfolios of publicly owned real estate in North America, including over 1,270 properties with 300 million square feet located in 46 states, District of Columbia, Puerto Rico and Ontario, Canada.  RMR has approximately 500 employees in its headquarters and regional offices located throughout the Country.  In addition to managing HRPT, RMR and its affiliates also manage Hospitality Properties Trust, a publicly traded REIT that owns hotels and travel centers, Senior Housing Properties Trust, a publicly traded REIT that owns senior living properties, and six publicly traded mutual funds, or RMR Funds, which principally invest in securities of real estate companies (excluding securities of companies managed by RMR and its affiliates).  The public companies managed by RMR and its affiliates had combined total market capitalization of nearly $16 billion as of September 30, 2007.  We believe that being managed by RMR is a competitive advantage for HRPT because RMR provides HRPT with a depth and quality of management and experience which may be unequaled in the real estate industry.  We also believe RMR provides management services to HRPT at costs that are lower than HRPT would have to pay for similar quality services.

We compute EBITDA, or earnings before interest, taxes, depreciation and amortization, as net income less gains on equity transactions of equity investments and gains on sales of properties, plus loss on early extinguishment of debt, interest expense, depreciation and amortization and the difference between EBITDA and earnings from equity investments.  We consider EBITDA to be an appropriate measure of our performance, along with net income and cash flow from operating, investing and financing activities.  We believe EBITDA provides useful information to investors because, by excluding the effects of certain historical costs, such as interest, depreciation and amortization expense, EBITDA can facilitate a comparison of our current operating performance with our past operating performance and of operating performances among REITs.  EBITDA does not represent cash generated by operating activities in accordance with generally accepted accounting principles, or GAAP, and should not be considered an alternative to net income or cash flow from operating activities as a measure of financial performance or liquidity.

We compute NOI as shown above.  We consider NOI to be an appropriate supplemental measure to net income available for common shareholders because it helps both investors and management to understand the operations of our properties.  We use NOI internally as a performance measure and believe NOI provides useful information to investors regarding our results of operations because it reflects only those income and expense items that are incurred at the property level.  Our management also uses NOI to evaluate individual, regional and company wide property level performance.  NOI excludes certain components from net income available for common shareholders in order to provide results that are more closely related to our properties’ results of operations.  NOI does not represent cash generated by operating activities in accordance with generally accepted accounting principles, or GAAP, and should not be considered an alternative to net income, net income available for common shareholders or cash flow from operating activities as a measure of financial performance.

We compute FFO, FFO available for common shareholders and diluted FFO available for common shareholders as shown above.  Our calculation of FFO differs from the National Association of Real Estate Investment Trusts, or NAREIT, definition because we add loss on early extinguishment of debt unless settled in cash.  We consider FFO to be an appropriate measure of performance for a REIT, along with net income and cash flow from operating, investing and financing activities. We believe that FFO provides useful information to investors because by excluding the effects of certain historical amounts, such as depreciation expense and gains or losses on sales of depreciated operating properties, FFO can facilitate a comparison of operating performances among REITs.  FFO does not represent cash generated by operating activities in accordance with generally accepted accounting principles, or GAAP, and should not be considered an alternative to net income or cash flow from operating activities as a measure of financial performance or liquidity.  FFO is one important factor considered by our Board of Trustees in determining the amount of distributions to shareholders.  Other important factors include, but are not limited to, requirements to maintain our status as a REIT, limitations in our revolving credit facility and public debt covenants, the availability of debt and equity capital to us and our expectations of future capital requirements and operating performance.
