                  WARNING CONCERNING FORWARD LOOKING STATEMENTS

     THIS DOCUMENT 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 RULED THAT OUR TERMINATION OF HEALTHSOUTH
     CORPORATION'S LEASE OF TWO HOSPITALS WAS PROPER AND ORDERED HEALTHSOUTH TO
     PAY US THE NET PATIENT REVENUES, LESS A MANAGEMENT FEE AND OPERATION COSTS,
     SINCE OCTOBER 26, 2004. HOWEVER, HEALTHSOUTH HAS FILED A NOTICE OF APPEAL
     OF THESE DECISIONS AND HEALTHSOUTH'S APPEAL MAY BE SUCCESSFUL.

o    A MASSACHUSETTS TRIAL COURT HAS ORDERED HEALTHSOUTH TO COOPERATE WITH US TO
     LICENSE A NEW TENANT FOR OUR HOSPITALS OPERATED BY HEALTHSOUTH. HEALTHSOUTH
     HAS FILED A NOTICE TO APPEAL THIS DECISION AND THAT APPEAL HAS NOT BEEN
     DECIDED, ALTHOUGH A STAY PENDING APPEAL SOUGHT BY HEALTHSOUTH WAS DENIED.
     HEALTHSOUTH RECENTLY FILED A MOTION IN THE TRIAL COURT SEEKING TO LIMIT ITS
     COOPERATION WITH THE LICENSING PROCESS AND FOR OTHER RELIEF. FUTURE ACTIONS
     BY HEALTHSOUTH, FUTURE DECISIONS BY COURTS WITH JURISDICTION OVER THESE
     MATTERS OR DECISIONS BY HEALTH REGULATORY AUTHORITIES MAY DELAY OR PREVENT
     OUR ENTERING A LEASE WITH A NEW TENANT FOR OUR HOSPITALS DESPITE THE
     EXISTING COURT ORDERS.

o    THE COURT HAS ORDERED HEALTHSOUTH TO CONTINUE OPERATIONS OF OUR 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 AND 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 IN THIS DOCUMENT
     REGARDING OUR LITIGATIONS WITH HEALTHSOUTH MAY BE THAT WE WILL EVENTUALLY
     RECOGNIZE MORE INCOME FROM OUR OWNERSHIP OF THE TWO HOSPITALS THAN $725,000
     PER MONTH. HOWEVER, THIS IMPLICATION MAY NOT BE REALIZED FOR MANY DIFFERENT
     REASONS: OUR REVIEW OF HEALTHSOUTH'S CALCULATIONS OF AMOUNTS DUE TO US MAY
     RESULT IN ADJUSTMENTS THAT DECREASE OR INCREASE THE FINAL AMOUNTS DUE TO
     US. 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. HEALTHSOUTH'S APPEAL MAY BE SUCCESSFUL AND ITS LEASE MAY BE
     REINSTATED. THE FINANCIAL RESULTS OF THE HOSPITALS' OPERATIONS MAY DECLINE
     AND THIS DECLINE MAY BE MATERIAL. IN FACT, HEALTHSOUTH MAY CEASE PAYING
     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 $2.7 MILLION
     IN LITIGATION COSTS. 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. WE HAVE REQUESTED THAT THE COURT ORDER
     HEALTHSOUTH TO PAY SOME OF OUR LITIGATION COSTS. HEALTHSOUTH HAS OPPOSED
     THIS REQUEST AND WE DO NOT KNOW HOW THE COURTS WILL RULE OR WHETHER
     HEALTHSOUTH WILL BE WILLING OR ABLE TO HONOR ANY AWARD WHICH MAY BE MADE.

YOU SHOULD NOT PLACE UNDUE RELIANCE UPON FORWARD LOOKING STATEMENTS. EXCEPT AS
MAY BE REQUIRED BY APPLICABLE LAW, WE UNDERTAKE NO OBLIGATION TO UPDATE OR
REVISE ANY FORWARD LOOKING STATEMENTS AS A RESULT OF NEW INFORMATION, FUTURE
EVENTS OR OTHERWISE.

                             CORPORATE INFORMATION









                         Senior Housing Properties Trust
                    Supplemental Operating and Financial Data
                                 March 31, 2006


                                 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, FTSE EPRA/NAREIT United States 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
March 31, 2006, RMR managed one of the largest portfolios of publicly owned real
estate in the United States, including approximately 980 properties, with
approximately 89.0 million square feet, located in 42 states, Washington, DC,
Puerto Rico and Ontario, Canada. RMR has over 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 and its
affiliates had combined total market capitalization of approximately $12.0
billion as of March 31, 2006. 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.
(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 17 were managed by Sunrise Senior Living,
     Inc., or Sunrise, at March 31, 2006. As of March 31, 2006, Five Star operated 13 of these 30 properties and intends to begin
     operating 10 additional properties during the second 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 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 first quarter for the 23 properties that Five Star currently manages and
     expects to manage in the second 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)  In March 2006, HealthSouth filed late an Annual Report on Form 10-K for the period ending December 31, 2005. The financial and
     operating data included in HealthSouth's Form 10-K show a substantial negative net worth and a history of substantial
     operating losses. Also, HealthSouth's management identified several material weaknesses in its internal control over
     financial reporting and stated that it did not maintain effective internal control over financial reporting as of December
     31, 2005. 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.
(9)  Brookdale Senior Living, Inc., or Brookdale, guarantees the lease for 18 properties leased to Alterra Healthcare Corporation,
     or Alterra.

<FN>

(1)  Rental income for the quarter ended March 31, 2006, includes $2.2 million of income from two
     hospitals operated by HealthSouth Corporation, or 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 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 to pay us the net patient revenues, after a 5%
     management fee and payment of costs and expenses of operation since October 26, 2004. 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 per month through January 2006. From February 1, 2006 to April 30, 2006, HealthSouth
     paid us an additional $6.0 million which HealthSouth represented to be amounts due from October 26,
     2004 to March 31, 2006. The supporting data for the calculations of amounts due to us provided by
     HealthSouth appears to be incomplete and contradictory. We have attempted to obtain accurate data
     and clarifications from HealthSouth, but HealthSouth has been unwilling or unable to provide such
     data. Pending the resolution of HealthSouth's appeal and the conclusion of our review of
     HealthSouth's calculations of amounts due to us, we have recognized in income only $2.2 million,
     which represents the minimum amount we are entitled to if HealthSouth prevails in its appeal and
     HealthSouth's lease is reinstated. We have deferred recognition of the remaining $4.5 million of
     cash payments received from HealthSouth. Under Internal Revenue Code laws and regulations applicable
     to real estate investment trusts, or REITs, a portion of the payments received from HealthSouth will
     be subject to income tax at corporate rates. We have also deferred recognition of $2.3 million of
     estimated tax expense, pending the recognition in income of the deferred payments received. In March
     2006, HealthSouth filed late an Annual Report on Form 10-K for the period ending December 31, 2005.
     The financial and operating data included in HealthSouth's Form 10-K show a substantial negative net
     worth and a history of substantial operating losses. Also, HealthSouth's management identified
     several material weaknesses in its internal control over financial reporting and stated that it did
     not maintain effective internal control over financial reporting as of December 31, 2005. 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)  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.

(3)  This amount represents rent with respect to the first quarter that is not included in rental income
     for the first quarter.  We recognize percentage rental income received during the first, second and
     third quarters in the fourth quarter.

(4)  These expenses relate to our HealthSouth litigation.

(1)  Net income includes legal expenses incurred related to our HealthSouth
     litigation of approximately $390,000 for the quarter ended March 31, 2006
     and $400,000 for the quarter ended March 31, 2005. See 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 this calculation total
     revenues for the first three quarters includes estimated amounts with
     respect to those periods. The fourth quarter calculation excludes the
     amounts recognized during the first three quarters.

     We compute EBITDA as shown in the calculation above. Such calculation
     begins with income from continuing operations or, if such amount is the
     same as net income, with net income. 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.

(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)  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. Such calculation begins
     with income from continuing operations or, if such amount is the same as
     net income, with net income. 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. 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)  In March 2006, HealthSouth filed late an Annual Report on Form 10K for the period ending December 31, 2005. The
     financial and operating data included in HealthSouth's Form 10-K show a substantial negative net worth and a
     history of substantial operating losses. Also, HealthSouth's management identified several material weaknesses in
     its internal control over financial reporting and stated that it did not maintain effective internal control over
     financial reporting as of December 31, 2005. 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)  These 30 properties are leased to Five Star and 17 were managed by Sunrise Senior Living, Inc.,
     or Sunrise, at March 31, 2006. As of March 31, 2006, Five Star operated 13 of these 30 properties
     and intends to begin operating 10 additional properties during the second 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 that Five Star pays to Sunrise, but 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 periods presented for the 23 properties that
     Five Star currently manages and expects to manage in the second quarter of 2006.
