                 WARNING CONCERNING FORWARD LOOKING STATEMENTS


     THIS SUPPLEMENTAL OPERATING AND FINANCIAL DATA REPORT CONTAINS FORWARD
LOOKING STATEMENTS WITHIN THE MEANING OF THE PRIVATE SECURITIES LITIGATION
REFORM ACT OF 1995 AND OTHER FEDERAL SECURITIES LAWS. THESE STATEMENTS REPRESENT
OUR PRESENT BELIEFS AND EXPECTATIONS, BUT THEY MAY NOT OCCUR FOR VARIOUS
REASONS. FOR EXAMPLE:

o    A MASSACHUSETTS TRIAL COURT HAS DECIDED THAT OUR TERMINATION OF
     HEALTHSOUTH'S LEASE OF TWO HOSPITALS WAS PROPER, HEALTHSOUTH IS TO
     COOPERATE WITH US IN LICENSING A NEW TENANT AND HEALTHSOUTH IS TO PAY US
     THE NET PATIENT REVENUES, LESS A MANAGEMENT FEE AND OPERATION COSTS, SINCE
     OCTOBER 26, 2004. HEALTHSOUTH HAS FILED A NOTICE OF APPEAL OF THESE
     DECISIONS AND HEALTHSOUTH'S APPEAL MAY BE SUCCESSFUL.

o    THE COURT HAS ORDERED HEALTHSOUTH TO CONTINUE OPERATIONS OF THE HOSPITALS
     DURING THE PERIOD OF TRANSITION TO A NEW TENANT. HEALTHSOUTH MAY BE
     UNWILLING OR UNABLE TO CONTINUE ITS OPERATIONS. IN SUCH CIRCUMSTANCES, WE
     MAY SEEK DAMAGES FROM HEALTHSOUTH AND TO CONTINUE THE HOSPITALS' OPERATIONS
     WITH APPROPRIATE REGULATORY APPROVALS, BUT WE MAY BE UNABLE TO COLLECT SUCH
     DAMAGES FROM HEALTHSOUTH OR TO CONTINUE THE HOSPITALS' OPERATIONS.

o    IN A SECOND LITIGATION, WE ARE SEEKING TO COLLECT INCREASED RENT FROM
     HEALTHSOUTH SINCE JANUARY 2002. THE FACT THAT WE HAVE RECEIVED A FAVORABLE
     RULING IN A SEPARATE LITIGATION MAY IMPLY THAT WE WILL ALSO SUCCEED IN THIS
     INCREASED RENT LITIGATION. HOWEVER, THE ISSUES IN THESE TWO LITIGATIONS ARE
     SOMEWHAT DIFFERENT. ALSO, THESE TWO CASES ARE PENDING IN DIFFERENT COURTS.
     WE BELIEVE ALL OF OUR CLAIMS ARE VALID. HOWEVER, NOT ALL OF OUR CLAIMS HAVE
     BEEN FINALLY DETERMINED AND THE FACT THAT WE HAVE RECEIVED FAVORABLE
     RULINGS IN ONE CASE DOES NOT MEAN WE WILL SUCCEED IN THE OTHER CASE.

o    THE IMPLICATION OF THE FORWARD LOOKING STATEMENTS REGARDING OUR LITIGATIONS
     WITH HEALTHSOUTH MAY BE THAT WE WILL EVENTUALLY RECEIVE MORE INCOME FROM
     OUR OWNERSHIP OF THE TWO HOSPITALS THAN THE $8.7 MILLION PER YEAR PAID BY
     HEALTHSOUTH SINCE JANUARY 2002 AND THE $4.6 MILLION WHICH HEALTHSOUTH PAID
     TO US IN FEBRUARY 2006. HOWEVER, THIS IMPLICATION MAY NOT BE REALIZED FOR
     MANY DIFFERENT REASONS: HEALTHSOUTH MAY BECOME UNABLE TO PAY THE INCREASED
     AMOUNTS, IF ANY, DUE TO US. WE MAY BE UNABLE TO IDENTIFY A NEW TENANT FOR
     THESE HOSPITALS WHO OBTAINS APPROPRIATE LICENSES AND WHO IS WILLING OR ABLE
     TO PAY INCREASED RENTS. THE FINANCIAL RESULTS OF THE HOSPITALS' OPERATIONS
     MAY DECLINE AND THIS DECLINE MAY BE MATERIAL. IN FACT, HEALTHSOUTH MAY
     CEASE PAYING THE $8.7 MILLION PER YEAR WHICH IT HAS HISTORICALLY PAID TO US
     OR OTHER AMOUNTS DUE TO US UNTIL A NEW TENANT IS INSTALLED AT THE
     HOSPITALS.

o    LITIGATION IS EXPENSIVE. SINCE THE CURRENT LITIGATIONS BETWEEN US AND
     HEALTHSOUTH BEGAN IN APRIL 2003, WE HAVE SPENT APPROXIMATELY $2.3 MILLION
     IN LITIGATION COSTS. THE EXPENSE OF THESE LITIGATIONS HAS BEEN SOMEWHAT
     CONCENTRATED DURING THE PAST 12 MONTHS. WE EXPECT THAT THESE EXPENSES WILL
     CONTINUE AND MAY INCREASE SO LONG AS THE LITIGATIONS CONTINUE. MOREOVER, WE
     ARE UNABLE TO PROVIDE ANY PROJECTIONS AS TO WHEN THESE LITIGATIONS MAY END
     OR THE AMOUNTS OF FUTURE LITIGATION COSTS.

     FOR ALL OF THE FOREGOING REASONS YOU ARE CAUTIONED NOT TO PLACE UNDUE
RELIANCE ON FORWARD LOOKING STATEMENTS. EXCEPT AS MAY BE REQUIRED BY APPLICABLE
LAW, WE DO NOT INTEND TO IMPLY THAT WE WILL RELEASE PUBLICLY THE RESULT OF ANY
REVISION TO THE FORWARD LOOKING STATEMENTS CONTAINED IN THIS REPORT.

                             CORPORATE INFORMATION



                        Senior Housing Properties Trust
                    Supplemental Operating and Financial Data
                                December 31, 2005

                                 COMPANY PROFILE
- -------------------------------------------------------------------------------
The Company:
Senior Housing Properties Trust, or SNH, is a real estate investment trust, or
REIT, which owns independent and assisted living properties, continuing care
retirement communities and nursing homes located throughout the United States.
We are included in a number of stock indices, including the Russell 2000(R), the
MSCI US REIT Index, NAREIT Real Time Index and the S&P REIT Composite Index.

Management:
Senior Housing Properties Trust is managed by Reit Management & Research LLC, or
RMR. RMR was founded in 1986 to manage public investments in real estate. As of
December 31, 2005, RMR managed one of the largest portfolios of publicly owned
real estate in the United States, including approximately 950 properties, with
approximately 86.0 million square feet, located in 42 states, Washington, DC,
Puerto Rico and Ontario, Canada. RMR has approximately 400 employees in its
headquarters and regional offices located throughout the country. In addition to
managing SNH, RMR and its affiliates also manage Hospitality Properties Trust, a
publicly traded REIT that owns hotels, HRPT Properties Trust, a publicly traded
REIT that primarily owns office buildings and four mutual funds which invest in
unaffiliated real estate companies. The public companies managed by RMR had
combined total market capitalization of approximately $12.0 billion as of
December 31, 2005. We believe that being managed by RMR is a competitive
advantage for SNH because RMR provides SNH with a depth of management and
experience which may be unequaled in the real estate industry. We also believe
RMR is able to provide management services to SNH at costs that are lower than
SNH would have to pay for similar quality services.

Strategy:
Our present business plan is to maintain an investment portfolio of independent
living properties, assisted living properties and nursing homes and to acquire
additional senior living properties primarily for income and secondarily for
appreciation potential. Our current growth strategy is generally focused on
making portfolio acquisitions of geographically diverse, primarily independent
and assisted senior living properties where the majority of the residents pay
for occupancy and services from private resources rather than through government
programs. We base our acquisition decisions on the historical and projected
operating results of the target properties and the financial strength of the
proposed tenants and their guarantors, among other considerations. Our present
financial strategy is to maintain a conservative capital structure which limits
the amount of debt that we issue. We do not have any investments in joint
ventures or partnerships. Also, the majority of our debt is fixed rate, and we
have no significant debt maturities until 2012.

<FN>
(1)  Represents the percentage of SNH's rental income that is derived from properties where the underlying operating
     revenues are greater than 80% private pay.
(2)  Amounts are before depreciation, but after impairment write downs, and include purchase price allocations related
     to FAS 141.
(3)  Properties where the majority of units are independent living apartments are classified as independent living
     communities.
(4)  All tenant operating data presented are based upon the operating results provided by our tenants for the indicated
     periods, or the most recent prior period for which tenant operating results are available to us from our tenants.
     Rent coverage is calculated as operating cash flow from our tenants' facility operations, before subordinated
     charges and capital expenditure reserves, divided by rent payable to us. We have not independently verified our
     tenants' operating data.
(5)  These 30 properties are leased to Five Star Quality Care, Inc., or Five Star, and 18 were managed by Sunrise
     Senior Living, Inc., or Sunrise, on December 31, 2005. As of December 31, 2005, Five Star operated 12 of these 30
     properties and intends to operate one additional property during the first quarter of 2006. Sunrise does not
     guaranty Five Star's lease obligations. The rent that Five Star pays to us is subordinate to the management fees
     paid by Five Star to Sunrise, but our rent is not subordinate to Five Star's internal management costs. The rent
     coverage presented for this lease has been adjusted to exclude management fees paid to Sunrise during the fourth
     quarter for the 13 properties that Five Star currently manages, and expects to manage, in the first quarter of
     2006.
(6)  Marriott International, Inc., or Marriott, guarantees the lease for these 14 properties leased to Sunrise.
(7)  Independence Blue Cross, or IBC, a Pennsylvania health insurer, guarantees the lease for the 10 properties leased
     to NewSeasons Assisted Living Communities, Inc., or NewSeasons.
(8)  During 2003, HealthSouth issued a press release stating that its historical financial information should not be
     relied upon. From that time until June 2005, HealthSouth had not filed audited financial information with the SEC.
     In June 2005, HealthSouth filed a restated Annual Report on Form 10-K, or Form 10K, for the period ending December
     31, 2003. In December 2005, HealthSouth late filed a Form 10K for the period ending December 31, 2004. The
     financial and operating data included in HealthSouth's Form 10-K's show a substantial negative net worth and a
     history of substantial operating losses. Because we do not have reliable current information about the operations
     or financial performance of HealthSouth or our hospitals, we do not show operating data for this operator. See
     also Note 1 on page 11 regarding our litigation with HealthSouth.

(1)  Rental income for the quarter and year ended December 31, 2005, includes $2.2 million and $8.7 million, respectively, of income
     from two hospitals operated by HealthSouth. Effective January 2, 2002, we entered an amended lease with HealthSouth for two
     hospitals. In April 2003, we commenced a lawsuit against HealthSouth seeking, among other matters, to reform the amended lease,
     based upon HealthSouth's fraud, by increasing the rent payable to us from January 2, 2002 until the termination or expiration
     of the amended lease. This litigation is pending at this time. On October 26, 2004, we terminated the amended lease for default
     because HealthSouth failed to deliver to us accurate and timely financial information as required by the amended lease. On
     November 2, 2004, HealthSouth brought a second lawsuit against us seeking to prevent our termination of the amended lease. On
     September 25, 2005, the court ruled that our termination was proper. On January 18, 2006, the court ordered HealthSouth to
     cooperate with us in licensing a new tenant and pay us the net patient revenues, after a 5% management fee and payment of costs
     and expenses of operation since October 26, 2004. We have begun working to identify and qualify a new tenant operator for the
     hospitals. HealthSouth has filed a notice of appeal of the court's decisions; but HealthSouth's motions for a stay of the
     court's decisions during the appeal have been denied by both the trial court and the appeals court. During the pendency of
     these disputes, HealthSouth continued to pay us at the disputed rent amount of $725,000/month, and, on February 3, 2006,
     HealthSouth paid us an additional $4.6 million which HealthSouth represented to be an amount due from November 1, 2004 to
     December 31, 2005. We are currently in the process of reviewing HealthSouth's calculations of amounts due to us and we may
     claim additional amounts. In June 2005, HealthSouth filed a restated Annual Report on Form 10-K for the period ending December
     31, 2003. In December 2005, HealthSouth filed late an Annual Report on Form 10-K for the period ending December 31, 2004. The
     financial and operating data included in HealthSouth's Form 10-Ks show a substantial negative net worth and a history of
     substantial operating losses. To date we have been unable to obtain reliable current financial information about the operations
     of HealthSouth or our hospitals. Accordingly, we do not know if we will be able to collect any additional amounts which the
     courts may determine to be owed to us by HealthSouth.

(2)  Included in interest and other income for the year ended December 31, 2004 is $1.25 million received in a settlement of
     litigation with Marriott.

(3)  Legal expenses incurred related to our HealthSouth litigation were approximately $600,000 and $1,850,000, respectively, for the
     quarter and year ended December 31, 2005 and $200,000 and $285,000, respectively, for the quarter and year ended December 31,
     2004, and are included in general and administrative expenses.

(4)  In December 2005, we called for redemption $52.5 million of our 7 7/8% senior unsecured notes. The loss on early extinguishment
     of debt includes a $4.1 million redemption premium and a $1.1 million write off of deferred finance fees and unamortized
     discount related to these $52.5 million of senior notes. The redemption occurred on January 9, 2006.

(5)  Includes costs associated with our litigations with HealthSouth (on going) and Marriott (settled in January 2004) and costs
     associated with a failed acquisition written off in the first quarter of 2004.

(6)  We recognize percentage rental income received during the first, second and third quarters in the fourth quarter. Although
     recognition of revenue is deferred until the fourth quarter, for purposes of this calculation, total revenues for the first
     three quarters included estimated amounts with respect to those periods. The fourth quarter calculation excludes the amounts
     recognized during the first three quarters.

(7)  We report rental income on a straight line basis over the terms of the respective leases. Rental income includes non-cash
     straight line rent adjustments.

(1)  Income from continuing operations includes legal expenses incurred related to our HealthSouth litigation
     of approximately $600,000 and $1,850,000, respectively, for the quarter and year ended December 31, 2005
     and $200,000 and $285,000, respectively, for the quarter and year ended December 31, 2004. See also Note 1
     on page 11 regarding our HealthSouth litigation.

(2)  We recognize percentage rental income received during the first, second and third quarters in the fourth
     quarter. Although recognition of revenue is deferred until the fourth quarter, for purposes of calculating
     this calculation, total revenues for the first three quarters included estimated amounts with respect to
     those periods. The fourth quarter calculation excludes the amounts recognized during the first three
     quarters.

We compute EBITDA as income from continuing operations plus interest expense,
depreciation expense, deferred percentage rent and non-recurring charges. We
consider EBITDA to be an appropriate measure of performance for a REIT, along
with net income and cash flow from operating, investing and financing
activities. EBITDA does not represent cash generated by operating activities in
accordance with generally accepted accounting principals, 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.

(1)  Income from continuing operations includes legal expenses incurred related to our HealthSouth litigation of approximately

(2)  We recognize percentage rental income received during the first, second and third quarters in the fourth quarter. Although
     recognition of revenue is deferred until the fourth quarter for purposes of calculating income from continuing operations, the
     calculation of FFO for the first three quarters includes estimated amounts with respect to those periods. The fourth quarter
     FFO calculation excludes the amounts recognized during the first three quarters.

(3)  FFO for the quarter and year ended December 31, 2005, include a $4.1 million, or $0.06 per share, loss for the cash premium
     paid for our redemption of $52.5 million of our 7 7/8% senior notes.

(4)  We report rental income on a straight line basis over the terms of the respective leases. Rental income includes non-cash
     straight line rent adjustments.

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 of FFO because we include deferred percentage rent in FFO as
discussed in Note 2 above and we exclude loss on early extinguishment of debt
not 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 costs, such as
depreciation expense and gain or loss on sale of properties, FFO can facilitate
a comparison of our current operating performance with our past operating
performance and of operating performance 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. 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 bank
credit facility and public debt covenants, the availability of debt and equity
capital to us and our expectation of our future performance.

(1)  This mortgage investment was a line of credit. The initial availability under this line of credit was
     for up to $43.5 million. At closing, $24.0 million was drawn and availability under the line of credit
     was reduced to $19.5 million. In August 2005, the $24.0 million was repaid by the borrower. We purchased
     the six properties that secured this line of credit on October 31, 2005 (See Acquisitions above) and,
     simultaneously, terminated the line of credit.

(1)  Amounts are before depreciation, but after impairment write downs, and include purchase price allocations related to FAS 141.

(2)  Properties where the majority of units are independent living apartments are classified as independent living communities.

(3)  Rental income for the quarter and year ended December 31, 2005, includes $2.2 million and $8.7 million, respectively, of income
     from two hospitals operated by HealthSouth. Effective January 2, 2002, we entered an amended lease with HealthSouth for two
     hospitals. In April 2003, we commenced a lawsuit against HealthSouth seeking, among other matters, to reform the amended lease,
     based upon HealthSouth's fraud, by increasing the rent payable to us from January 2, 2002 until the termination or expiration
     of the amended lease. This litigation is pending at this time. On October 26, 2004, we terminated the amended lease for default
     because HealthSouth failed to deliver to us accurate and timely financial information as required by the amended lease. On
     November 2, 2004, HealthSouth brought a second lawsuit against us seeking to prevent our termination of the amended lease. On
     September 25, 2005, the court ruled that our termination was proper. On January 18, 2006, the court ordered HealthSouth to
     cooperate with us in licensing a new tenant and pay us the net patient revenues, after a 5% management fee and payment of costs
     and expenses of operation since October 26, 2004. We have begun working to identify and qualify a new tenant operator for the
     hospitals. HealthSouth has filed a notice of appeal of the court's decisions; but HealthSouth's motions for a stay of the
     court's decisions during the appeal have been denied by both the trial court and the appeals court. During the pendency of
     these disputes, HealthSouth continued to pay us at the disputed rent amount of $725,000/month, and, on February 3, 2006,
     HealthSouth paid us an additional $4.6 million which HealthSouth represented to be an amount due from November 1, 2004 to
     December 31, 2005. We are currently in the process of reviewing HealthSouth's calculations of amounts due to us and we may
     claim additional amounts. In June 2005, HealthSouth filed a restated Annual Report on Form 10-K for the period ending December
     31, 2003. In December 2005, HealthSouth filed late an Annual Report on Form 10-K for the period ending December 31, 2004. The
     financial and operating data included in HealthSouth's Form 10-Ks show a substantial negative net worth and a history of
     substantial operating losses. To date we have been unable to obtain reliable current financial information about the operations
     of HealthSouth or our hospitals. Accordingly, we do not know if we will be able to collect any additional amounts which the
     courts may determine to be owed to us by HealthSouth.

(4)  These 30 properties are leased to Five Star and 18 are were managed by Sunrise on December 31, 2005. As of December 31, 2005,
     Five Star operated 12 of these 30 properties and intends to operate one additional property during the first quarter of 2006.
     Sunrise does not guaranty Five Star's lease obligations.

(5)  Marriott guarantees the lease for the 14 properties leased to Sunrise.

(6)  IBC guarantees the lease for the 10 properties leased to NewSeasons.

(1)  This lease includes 30 properties leased to Five Star. Eighteen of these properties were managed by
     Sunrise on December 31, 2005. Beginning in November 2005, Five Star operated 12 of these 30 properties
     and intends to begin to operate one additional property during the first quarter of 2006. The rent that
     Five Star pays to us is subordinate to the management fees paid by Five Star to Sunrise, but our rent is
     not subordinate to Five Star's internal management costs. The rent coverages presented for this lease
     have been adjusted to exclude management fees paid to Sunrise during the respective period for the 13
     properties that Five Star currently manages and expects to manage in the first quarter of 2006.

     All tenant operating data presented are based upon the operating results provided by our tenants for
     the indicated periods, or the most recent prior period for which tenant operating results are available
     to us from our tenants. Rent coverage is calculated as operating cash flow from our tenants' facility

     payable to us. We have not independently verified our tenants' operating data.

(1)  Excludes the two hospitals operated by HealthSouth. Effective January 2,
     2002, we entered an amended lease with HealthSouth for two hospitals. In
     April 2003, we commenced a lawsuit against HealthSouth seeking, among other
     matters, to reform the amended lease, based upon HealthSouth's fraud, by
     increasing the rent payable to us from January 2, 2002 until the
     termination or expiration of the amended lease. This litigation is pending
     at this time. On October 26, 2004, we terminated the amended lease for
     default because HealthSouth failed to deliver to us accurate and timely
     financial information as required by the amended lease. On November 2,
     2004, HealthSouth brought a second lawsuit against us seeking to prevent
     our termination of the amended lease. On September 25, 2005, the court
     ruled that our termination was proper. On January 18, 2006, the court
     ordered HealthSouth to cooperate with us in licensing a new tenant and pay
     us the net patient revenues, after a 5% management fee and payment of costs
     and expenses of operation, since October 26, 2004. We have begun working to
     identify and qualify a new tenant operator for the hospitals. HealthSouth
     has filed a notice of appeal of the court's decisions; but HealthSouth's
     motions for a stay of the court's decisions during the appeal have been
     denied by both the trial court and the appeals court. During the pendency
     of these disputes, HealthSouth has continued to pay us at the disputed rent
     amount of $725,000/month, and, on February 3, 2006, HealthSouth paid us an
     additional $4.6 million which HealthSouth represented to be an amount due
     from November 1, 2004 to December 31, 2005. We are currently in the process
     of reviewing HealthSouth's calculations of amounts due to us and we may
     claim additional amounts. In June 2005, HealthSouth filed a restated Annual
     Report on Form 10-K for period ending December 31, 2003. In December 2005,
     HealthSouth filed late an Annual Report on Form 10-K for the period ending
     December 31, 2004. The financial and operating data included in
     HealthSouth's Form 10-K's show a substantial negative net worth and a
     history of substantial operating losses. To date we have been unable to
     obtain reliable current financial information about the operations of
     HealthSouth or our hospitals. Accordingly, we do not know if we will be
     able to collect any additional amounts which the courts may determine to be
     owed to us by HealthSouth.
