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

As of June 30, 2009, 89.1% of HRP’s total square feet was leased, compared to 89.5% as of March 31, 2009 and 90.9% as of June 30, 2008.

HRP signed lease renewals for 992,000 square feet and new leases for 650,000 square feet during the quarter ended June 30, 2009, for weighted average rental rates that were 2% below prior rents for the same space. Average lease terms for leases signed during the second quarter of 2009 were 7.7 years. Commitments for tenant improvement and leasing commission (TI/LC) costs for leases signed during the quarter ended June 30, 2009 totaled $13.25 per square foot on a weighted average basis.

Investing Activities:

During the second quarter of 2009, HRP acquired one office property with 670,000 square feet of space for $134.3 million, excluding closing costs and one industrial property with 645,000 square feet of space for $34.0 million, excluding closing costs. HRP also sold two properties during the second quarter of 2009 with 193,000 square feet of space for $50.8 million, excluding closing costs, and realized a gain on sale of properties of $20.3 million.

Financing Activities:

During the second quarter of 2009, HRP repurchased and retired $77.7 million face amount of its publicly issued debt securities for $64.0 million and realized a gain on early extinguishment of debt of $13.2 million, net of unamortized issuance costs and discounts.

During April 2009, HRP transferred 29 properties with 3.3 million square feet to its wholly owned subsidiary, Government Properties Income Trust, or GOV, a real estate investment trust that owns properties that are majority leased to government tenants. Also in April 2009, GOV entered into a new $250 million secured credit facility with a group of commercial banks. The $250 million proceeds of this credit facility were distributed by GOV to HRP and used to repay amounts outstanding under HRP’s revolving credit facility. In June 2009, GOV completed an initial public offering of 11.5 million common shares and became a separate public company. Simultaneous with the closing of the GOV IPO, the $250 million secured credit facility was transferred to GOV and is no longer an obligation of HRP’s. HRP continues to own 9.95 million common shares, or 46.4%, of GOV with a book carrying value of $153.1 million and a market value of $204.3 million as of June 30, 2009.

In January 2009, HRP announced that its Board authorized a buy back program for up to $100 million of common shares during 2009. Through June 30, 2009 HRP has purchased 4,050,000 common shares at an average price of $3.57/share. HRP has not repurchased any additional shares since June 30 through today. Although this repurchase authority has not been rescinded, in view of the recent increases in the trading prices of common shares of REITs, including HRP, and the continuation of restrictive conditions in the debt markets, it now appears that HRP may not spend the full authorized amount for common share purchases before the end of 2009, unless capital market conditions change.

Conference Call:

(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 exclude acquisition costs as described in Note 2 below, gain on early extinguishment of debt and 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 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.

(2) Acquisition costs have been expensed under Statement of Financial Accounting Standards No. 141(R), “Business Combinations” since January 1, 2009.

(3) As of June 30, 2009, 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 and six months ended June 30, 2009 and 2008. 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.
