Explanatory Note

As previously reported in a Current Report on Form 8-K dated May 9, 2008, or the May 9 Current Report, filed by Senior Housing Properties Trust, or SNH, or us or we, we agreed to purchase up to 48 medical office, clinic and biotech laboratory buildings, or MOBs, from HRPT Properties Trust, or HRPT, pursuant to a series of Purchase and Sale Agreements, or the Purchase Agreements, dated as of May 5, 2008.  The agreements to purchase these 48 MOBs were more fully described in the May 9 Current Report.  Financial statements and pro forma financial information required by Items 9(a) and (b) of Form 8-K in connection with the matters reported in the May 9 Current Report were reported by us in the May 9 Current Report and amended in our Current Report on Form 8-K/A dated May 22, 2008, or the May 22 Current Report, and in our Current Report on Form 8-K/A dated September 29, 2008, or the September 29 Current Report.  As of the date of this Current Report on Form 8-K, we have purchased 29 of the MOBs from HRPT.  In addition,

1

Table of Contents

because a third party consent was not received, one of the Purchase Agreements was amended so that one of the remaining 19 MOBs is no longer subject to the Purchase Agreements.  Nonetheless, HRPT may receive such third party consent and we may ultimately purchase that MOB.  We previously reported the closings of the purchase of 28 of these MOBs in our Current Report on Form 8-K dated August 12, 2008, or the August 12 Current Report, and in our September 29 Current Report.

This Current Report on Form 8-K provides updated unaudited pro forma financial statements reflecting the purchase of 29 of the MOBs, as well as the pending acquisitions of the remaining 18 MOBs subject to the Purchase Agreements and the one remaining MOB that is no longer subject to the Purchase Agreements, but that we still believe we will purchase.  The updated pro forma financial statements also reflect unrelated properties we have purchased through December 16, 2008.

Item 9.01.  Financial Statements and Exhibits.

This Current Report on Form 8-K includes pro forma financial data for us, which includes the 29 MOBs that have been acquired and the 19 MOBs proposed to be acquired from HRPT as well as other acquisitions we have completed since January 1, 2008 (balance sheet) and January 1, 2007 (statements of income).  Because changes will likely occur in occupancy, rents and expenses with respect to the properties to be acquired and because some or all of the acquisitions may not be completed, the pro forma financial data presented should not be considered as a projection of future results.  Differences could also result from, among other considerations, changes in our portfolio of investments, in interest rates and in our capital structure.

In the August 12 Current Report, we reported our acquisition pursuant to certain of the Purchase Agreements of the first 28 MOBs in California, Georgia, Massachusetts, New York, Pennsylvania, Texas and Rhode Island for an aggregate purchase price of $232.7 million, excluding closing costs.  These acquisitions consisted of five medical office properties acquired in June 2008 for approximately $83.8 million, three medical office and clinic properties acquired on July 9, 2008 for approximately $39.1 million and 20 clinic buildings acquired on August 8, 2008 for approximately $109.9 million.  Subsequent to the September 29 Current Report, o n October 31, 2008, we acquired one additional medical office building from HRPT for approximately $29.8 million, excluding closing costs.  We funded these acquisitions using cash on hand, proceeds from our equity issuances, borrowings under our revolving credit facility and by assuming three mortgage loans on two properties totaling $10.8 million with a weighted average interest rate of 7.1% per annum.

Between January 1, 2008 and December 16, 2008, we acquired the following other properties from unaffiliated parties (dollars in thousands):

Table of Contents

(1) On August 21, 2008, we acquired four wellness centers with a total of 458,000 square feet.

(2) On September 30, 2008, we acquired one medical office building from an unaffiliated party with a total of 89,000 square feet.

We funded these acquisitions using cash on hand, proceeds from equity issuances, borrowings under our revolving credit facility and by assuming 15 mortgage loans for $50.5 million on eight of these properties.

Certain properties acquired by us, or proposed to be acquired from HRPT, are leased to various tenants, including Five Star Quality Care, Inc., or Five Star, on a long term basis under net leases that transfer substantially all of the properties’ operating and holding costs to the tenants. We have previously provided summary financial data and other information for Five Star in our Amendment No. 1 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2007, and in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2008. The remaining tenants with net leases are engaged in a range of industries including health services, biotechnology research, and pharmaceutical research and manufacturing with no significant concentration within any particular industry.  The majority of these net lease tenants are privately owned.  Certain leases are guaranteed by affiliates of the tenants.  As of the date of this report, we believe that each tenant is current in its rent payments.  Five of the significant net lease tenants, other than Five Star, are: Scripps Research Institute, or Scripps; Fallon Community Health Plan, or Fallon Clinic; Health Insurance Plan of New York, or HIP; EPIX Pharmaceuticals, Inc., or EPIX; and The Oklahoma City Clinics.  Scripps is one of the largest non-profit research institutes in the Country and is located in La Jolla, California.  Fallon Clinic is one of the largest multi-specialty group practices providing healthcare services in Central Massachusetts.   HIP is one of the largest health care companies providing health care services to approximately 1.4 million individuals.  EPIX is a biopharmaceutical company focused on discovering and developing novel therapeutics.  EPIX is listed on NASDAQ Global Market under the symbol “EPIX”.  The Oklahoma City Clinics are a medical practice group operating in Oklahoma City and the surrounding area.

Introduction to Unaudited Pro Forma Condensed Consolidated Financial Statements

The following unaudited pro forma condensed consolidated balance sheet as of September 30, 2008, reflects our financial position as if the transactions described in the footnotes to the unaudited pro forma condensed consolidated financial statements were completed on September 30, 2008.  The unaudited pro forma condensed consolidated statements of income for the nine months ended September 30, 2008, and the year ended December 31, 2007, present our results of operations as if the transactions described in the notes to the unaudited pro forma condensed consolidated financial statements were completed on January 1, 2007.  These unaudited pro forma condensed consolidated financial statements should be read in conjunction with our financial statements for the three and nine months ended September 30, 2008, included in our Quarterly Report on Form 10-Q, our financial statements for the year ended December 31, 2007, included in our Annual Report on Form 10-K, and the financial statements included in our Current Report on Form 8-K dated May 9, 2008 and in our Current Report on Form 8-K/A dated May 22, 2008.

The unaudited pro forma financial statements assume the acquisitions of 48 medical office, clinic and biotech laboratory buildings, or MOBs, from HRPT Properties Trust, or HRPT, are financed with cash on hand, borrowings under our revolving credit facility and by assuming three mortgage debts on two of the properties totaling $10.8 million.  We expect to eventually fund these acquisitions with a mix of long term capital determined based upon market conditions.  These unaudited pro forma financial statements are provided for informational purposes only and upon completion of the planned long term financing for these acquisitions our financial position and results of our operations will be significantly different than what is presented in these unaudited pro forma financial statements.  In the opinion of management, all adjustments necessary to reflect the effects of the transactions described above have been included in the pro forma financial statements.

The allocation of the purchase prices of the acquisitions of the MOBs from HRPT and the other property acquisitions described in the notes to the unaudited pro forma condensed financial statements and reflected in these unaudited pro forma condensed consolidated financial statements have been based upon preliminary estimates of the fair value of assets acquired and liabilities assumed.  A final determination of the fair values of the MOBs acquired or to be acquired will be based on the actual net tangible and intangible assets that exist as of the dates of the completion of the transactions.  Consequently, amounts preliminarily allocated to assets acquired and liabilities assumed could change significantly from those used in the unaudited pro forma financial statements.

These unaudited pro forma financial statements are not necessarily indicative of the expected results of operations for any future period.  Differences will result if the acquisitions of the MOBs from HRPT are not completed as planned.  Differences could also result from, among other considerations, future changes in our portfolio of investments, changes in interest rates, changes in our capital structure, changes in property level operating expenses, and changes in property level revenues including rents expected to be received on leases in place or signed

during and after 2008.  Consequently, amounts presented in the unaudited pro forma financial statements related to these transactions are likely to be different than actual future results.
