The weighted average number of basic and diluted common shares outstanding totaled 226,926,908 and 256,119,566, respectively, for the quarter ended March 31, 2010, and 225,619,502 and 254,812,160, respectively, for the quarter ended March 31, 2009.

A Maryland Real Estate Investment Trust with transferable shares of beneficial interest listed on the New York Stock Exchange.  No shareholder, Trustee or officer is personally liable for any act or obligation of the Trust.

Occupancy and Leasing Results (excluding properties classified in discontinued operations):

As of March 31, 2010, 86.6% of HRP’s total square feet was leased, compared to 87.4% as of December 31, 2009 and 89.5% as of March 31, 2009.

HRP signed lease renewals for 1,098,000 square feet and new leases for 425,000 square feet during the quarter ended March 31, 2010 which had weighted average rental rates that were 2% above prior rents for the same space.  Average lease terms for leases signed during the first quarter of 2010 were 6.4 years.  Commitments for tenant improvement and leasing commission (TI/LC) costs for leases signed during the quarter ended March 31, 2010 totaled $11.27 per square foot on average.

Recent Investment Activities:

Since April 1, 2010, HRP has acquired two properties and it has entered agreements to acquire 12 additional properties for an aggregate purchase price of $192.9 million, which excludes closing costs:

·In April 2010, HRP acquired an office property located in Denver, CO with 248,493 square feet.  This property is 100% leased to RE/MAX Realty as its corporate headquarters through 2028.  The purchase price was $75.0 million, excluding closing costs.

·In April 2010, HRP acquired an office property located in Colorado Springs, CO with 77,411 square feet.  The property is 100% leased to two tenants for a weighted (by rents) average lease term of approximately 4.7 years.  The purchase price is $10.8 million, excluding closing costs.

·In May 2010, HRP entered a purchase and sale agreement to acquire two office properties located in Carson, CA with a combined 212,000 square feet.  These properties are 100% leased to Northrop Grumman through 2016.  The purchase price is $27.9 million, excluding closing costs.  HRP expects to acquire these properties during the second quarter of 2010; however, this acquisition is subject to customary closing conditions and no assurance can be given that this acquisition will be consummated in that time period or at all.

2

·In May 2010, HRP entered an agreement to acquire MacarthurCook Industrial Property Fund, an Australian listed property trust with units publicly traded on the Australian Securities Exchange under the symbol “MIF”.  MIF currently owns 10 industrial properties with approximately 1.4 million square feet which are approximately 90% leased to 16 tenants for a weighted (by rents) average lease term of approximately five years.  The MIF properties are located in five Australian states: New South Wales (3 properties), Victoria (2 properties), Western Australia (2 properties), Tasmania (2 properties) and Queensland (1 property).  The total consideration is approximately $79.2 million, excluding closing costs, and closing is expected during the second half of 2010.  HRP’s acquisition of MIF is conditioned upon approval of MIF’s unitholders and other customary conditions, including certain conditions applicable to cross border transactions such as Foreign Investment Review Board approval in Australia and various tax rulings; accordingly, these conditions may not be satisfied, the required approvals may not be obtained and this transaction may not close.

Recent Financing Activities:

During the first quarter of 2010, HRP issued 34.5 million common shares in a public offering, raising net proceeds of approximately $239.1 million.  HRP used the net proceeds from this offering to repay amounts outstanding under its revolving credit facility and for general business purposes, including property acquisitions completed after March 31, 2010.

As of both March 31, 2010 and May 5, 2010, HRP had zero drawn and the entire amount available under its $750 million unsecured revolving credit facility.

Conference Call:

On Thursday, May 6, 2010, at 1:00 p.m. Eastern Time, Adam Portnoy, Managing Trustee, and John Popeo, Chief Financial Officer, will host a conference call to discuss the first quarter results.  Following the company’s remarks, there will be a short question and answer period.

The conference call telephone number is (888) 668-1638.  Participants calling from outside the United States and Canada should dial (913) 312-1477.  No pass code is necessary to access either call.  Participants should dial in about 15 minutes prior to the scheduled start of the call.  A replay of the conference call will be available through 4:00 p.m. Eastern Time on Thursday, May 13, 2010.  To hear the replay, dial (719) 457-0820.  The replay pass code is 4401435.

(1)Represents the closing costs associated with acquisitions that are expensed under the Business Combinations Topic of the FASB Accounting Standards CodificationTM.

(2)We compute FFO as shown in the calculation above.  Our calculation of FFO differs from the National Association of Real Estate Investment Trusts, or NAREIT, definition because we exclude acquisition costs as described in Note 1 above, gains from equity investments and gain on early extinguishment of debt, loss on early extinguishment of debt unless settled in cash, and loss on asset impairment.  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 items referred to above, FFO can facilitate a comparison of operating performance between periods and 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.  Also, some REITs may calculate FFO differently than us.

(3)As of March 31, 2010, our 15,180 outstanding series D preferred shares were convertible into 29,193 common shares.  The effect of a conversion of our series D convertible preferred shares on income from continuing operations available for common shareholders per share is anti-dilutive to income, but dilutive to FFO for the quarters ended March 31, 2010 and 2009.  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.

WARNING REGARDING

FORWARD LOOKING STATEMENTS

THIS SUPPLEMENTAL OPERATING AND FINANCIAL DATA CONTAINS STATEMENTS WHICH CONSTITUTE FORWARD LOOKING STATEMENTS WITHIN THE MEANING OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 AND OTHER FEDERAL SECURITIES LAWS. WHENEVER WE USE WORDS SUCH AS “BELIEVE”, “EXPECT”, “ANTICIPATE”, “INTEND”, “PLAN”, “ESTIMATE” OR SIMILAR EXPRESSIONS, WE ARE MAKING FORWARD LOOKING STATEMENTS. THESE FORWARD LOOKING STATEMENTS ARE BASED UPON OUR PRESENT INTENT, BELIEFS OR EXPECTATIONS, BUT FORWARD LOOKING STATEMENTS AND THEIR IMPLICATIONS ARE NOT GUARANTEED TO OCCUR AND MAY NOT OCCUR. FORWARD LOOKING STATEMENTS AND THEIR IMPLICATIONS IN THIS REPORT RELATE TO VARIOUS ASPECTS OF OUR BUSINESS, INCLUDING:

·THE CREDIT QUALITY OF OUR TENANTS,

·THE LIKELIHOOD THAT OUR TENANTS WILL PAY RENT, RENEW LEASES, SIGN NEW LEASES OR BE AFFECTED BY CYCLICAL ECONOMIC CONDITIONS,

·OUR ACQUISITIONS AND SALES OF PROPERTIES,

·OUR ABILITY TO COMPETE FOR ACQUISITIONS AND TENANCIES EFFECTIVELY,

·OUR ABILITY TO PAY INTEREST ON AND PRINCIPAL OF OUR DEBT,

·OUR ABILITY TO PAY DISTRIBUTIONS TO SHAREHOLDERS,

·OUR POLICIES AND PLANS REGARDING INVESTMENTS AND FINANCINGS,

·THE FUTURE AVAILABILITY OF BORROWINGS UNDER, AND OUR ABILITY TO RENEW OR REFINANCE, OUR REVOLVING CREDIT FACILITY,

·OUR TAX STATUS AS A REAL ESTATE INVESTMENT TRUST, OR REIT

·OUR ABILITY TO RAISE EQUITY OR DEBT, AND

·OTHER MATTERS.

OUR ACTUAL RESULTS MAY DIFFER MATERIALLY FROM THOSE CONTAINED IN OR IMPLIED BY OUR FORWARD LOOKING STATEMENTS AS A RESULT OF VARIOUS FACTORS. FACTORS THAT COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR FORWARD LOOKING STATEMENTS AND UPON OUR BUSINESS, RESULTS OF OPERATIONS, FINANCIAL CONDITION, FUNDS FROM OPERATIONS, CASH FLOWS, LIQUIDITY AND PROSPECTS INCLUDE, BUT ARE NOT LIMITED TO:

·THE IMPACT OF CHANGES IN THE ECONOMY AND THE CAPITAL MARKETS ON US AND OUR TENANTS,

·COMPETITION WITHIN THE REAL ESTATE INDUSTRY OR THOSE INDUSTRIES IN WHICH OUR TENANTS OPERATE,

·ACTUAL AND POTENTIAL CONFLICTS OF INTEREST WITH OUR MANAGING TRUSTEES AND OUR MANAGER, REIT MANAGEMENT & RESEARCH, LLC, OR RMR, AND ITS RELATED ENTITIES AND CLIENTS,

·COMPLIANCE WITH, AND CHANGES TO, FEDERAL, STATE AND LOCAL LAWS AND REGULATIONS, ACCOUNTING RULES, TAX RATES AND SIMILAR MATTERS, AND

·LIMITATIONS IMPOSED ON OUR BUSINESS AND OUR ABILITY TO SATISFY COMPLEX RULES IN ORDER FOR US TO QUALIFY AS A REIT FOR U.S. FEDERAL INCOME TAX PURPOSES.

FOR EXAMPLE:

·IF THE AVAILIBILITY OF DEBT CAPITAL BECOMES MORE RESTRICTED, WE MAY BE UNABLE TO REFINANCE OR REPAY OUR DEBT OBLIGATIONS WHEN THEY BECOME DUE OR ON TERMS WHICH ARE AS FAVORABLE AS WE NOW HAVE,

·THE CURRENT HIGH UNEMPLOYMENT RATE IN THE U.S. MAY CONTINUE FOR A LONG TIME OR BECOME WORSE IN THE FUTURE. SUCH CIRCUMSTANCES MAY FURTHER REDUCE DEMAND FOR LEASING OFFICE AND INDUSTRIAL SPACE. IF THE DEMAND FOR LEASING OFFICE AND INDUSTRIAL SPACE REMAINS AT CURRENT LEVELS OR BECOMES FURTHER DEPRESSED, OCCUPANCY AND OPERATING RESULTS OF OUR PROPERTIES MAY DECLINE,

·SOME OF OUR TENANTS MAY NOT RENEW EXPIRING LEASES, AND WE MAY BE UNABLE TO LOCATE NEW TENANTS TO MAINTAIN THE HISTORICAL OCCUPANCY RATES OF OUR PROPERTIES,

·OUR AGREEMENTS TO ACQUIRE ADDITIONAL PROPERTIES ARE SUBJECT TO VARIOUS TERMS AND CONDITIONS, AND THESE TERMS AND CONDITIONS MAY NOT BE MET. AS A RESULT, SOME OR ALL OF THESE TRANSACTIONS MAY NOT OCCUR OR MAY BE DELAYED,

·OUR ABILITY TO MAKE FUTURE DISTRIBUTIONS DEPENDS UPON OUR FUTURE EARNINGS. WE MAY BE UNABLE TO MAINTAIN OUR CURRENT RATE OF DISTRIBUTIONS AND FUTURE DISTRIBUTIONS MAY BE SUSPENDED OR PAID AT A LESSER RATE THAN THE DISTRIBUTIONS WE NOW PAY,

·OUR ABILITY TO GROW OUR BUSINESS AND INCREASE OUR DISTRIBUTIONS DEPENDS IN LARGE PART UPON OUR ABILITY TO BUY PROPERTIES AND LEASE THEM FOR RENTS THAT EXCEED OUR CAPITAL COSTS. WE MAY BE UNABLE TO IDENTIFY PROPERTIES THAT WE WANT TO ACQUIRE OR TO NEGOTIATE ACCEPTABLE PURCHASE PRICES, ACQUISITION FINANCING OR LEASE TERMS FOR NEW PROPERTIES,

·THE DIVIDENDS WE RECEIVE FROM OUR SHARES IN GOVERNMENT PROPERTIES INCOME TRUST, OR GOV, MAY DECLINE, OR WE MAY BE UNABLE TO SELL OUR GOV SHARES FOR AN AMOUNT EQUAL TO OUR CARRYING VALUE OF THOSE SHARES, AND

·OTHER RISKS MAY ADVERSELY IMPACT US, AS DESCRIBED MORE FULLY UNDER “ITEM 1A. RISK FACTORS” IN OUR ANNUAL REPORT ON FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 2009.

THESE RESULTS COULD OCCUR DUE TO MANY DIFFERENT CIRCUMSTANCES, SOME OF WHICH ARE BEYOND OUR CONTROL, SUCH AS CHANGES IN OUR TENANTS’ FINANCIAL CONDITIONS OR THE MARKET DEMAND FOR LEASED SPACE, OR CHANGES IN THE CAPITAL MARKETS OR THE ECONOMY GENERALLY.

YOU SHOULD NOT PLACE UNDUE RELIANCE UPON OUR FORWARD LOOKING STATEMENTS.

EXCEPT AS REQUIRED BY LAW, WE DO NOT INTEND TO UPDATE OR CHANGE ANY FORWARD LOOKING STATEMENTS AS A RESULT OF NEW INFORMATION, FUTURE EVENTS OR OTHERWISE.

CORPORATE INFORMATION

HRPT Properties Trust

Supplemental Operating and Financial Data

March 31, 2010

COMPANY PROFILE

The Company:

HRPT Properties Trust, or HRP, is a real estate investment trust, or REIT, which primarily owns office and industrial buildings located throughout the United States. The majority of our properties are office buildings located in suburban areas and central business districts, or CBDs, of major metropolitan markets. As of March 31, 2010, we also owned 17.9 million square feet of leased industrial and commercial lands in Oahu, Hawaii. 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 our leased lands in Hawaii. The growth part of our portfolio includes our multi-tenant 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 generally consider ourselves to be a long term investor and we 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 off balance sheet entities.

Management:

HRP is managed by Reit Management & Research LLC, or RMR. RMR is a real estate management company which was founded in 1986 to manage public investments in real estate. As of March 31, 2010, RMR managed one of the largest portfolios of publicly owned real estate in North America, including 1,360 properties, located in 45 states, Washington, DC, Puerto Rico and Ontario, Canada. RMR has more than 600 employees in its headquarters and regional offices located throughout the U.S. In addition to managing HRP, RMR also manages Hospitality Properties Trust, or HPT, a publicly traded REIT that owns hotels and travel centers, Senior Housing Properties Trust, or SNH, a publicly traded REIT that primarily owns healthcare properties, and Government Properties Income Trust, or GOV, a publicly traded REIT that primarily owns buildings majority leased to government tenants located throughout the U.S. RMR also provides management services to Five Star Quality Care, Inc., a healthcare services company which is a tenant of SNH, and to TravelCenters of America LLC, an operator of travel centers which is a tenant of HPT. An affiliate of RMR, RMR Advisors, Inc., is the investment manager of mutual funds which principally invests in securities of unaffiliated real estate companies. The public companies managed by RMR and its affiliates had combined total gross assets of over $17.0 billion as of March 31, 2010. We believe that being managed by RMR is a competitive advantage for HRP because RMR provides us 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 HRP at costs that are lower than we would have to pay for similar quality services.

We compute NOI as shown above. We consider NOI to be an appropriate supplemental measure to net income 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 U.S. 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.

EBITDA	$	119,285		$	119,266

We compute EBITDA, or earnings before interest, taxes, depreciation and amortization, as net income less gains on sales of properties, gain on early extinguishment of debt and gain on issuance of shares by equity investees, plus interest expense, income tax expense, depreciation and amortization, loss on asset impairment and EBITDA from equity investments, less equity in earnings of 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 noted above, 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 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. Also, some REITs may calculate EBITDA differently than us.

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 exclude acquisition costs as described in Note 1 above, gains from equity investments, gain on early extinguishment of debt, loss on early extinguishment of debt unless settled in cash, and loss on asset impairment. 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 items referred to above, FFO can facilitate a comparison of operating performance between periods and among REITs. FFO does not represent cash generated by operating activities in accordance with 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. Also, some REITs may calculate FFO differently than us.
