                         Senior Housing Properties Trust
                    Supplemental Operating and Financial Data
                                  June 30, 2005


                                 COMPANY PROFILE
- --------------------------------------------------------------------------------

The Company:
- ------------
Senior Housing Properties Trust 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.
All of our properties are triple net leased, meaning that each tenant pays us
rent, but remains responsible to pay all operating costs, taxes, insurance and
maintenance costs that arise from the use of our property. Our 184 properties
are leased to eleven tenants under 12 leases. 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 publicly owned investments in real
estate. As of June 30, 2005, RMR managed one of the largest portfolios of
publicly owned real estate in the United States, including approximately 900
properties, with approximately 83.5 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 over
$11.5 billion as of June 30, 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.
(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 31 properties  are leased to Five Star Quality Care,  Inc., or Five Star,  and 30 are managed by Sunrise  Senior  Living,
     Inc., or Sunrise. Sunrise does not guaranty Five Star's lease obligations.
(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 Report 10-K for periods ending  December 31, 2003. The financial and operating data included in  HealthSouth's
     restated Report 10-K 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 3 on page 21 regarding our litigation with HealthSouth.

(1)  Rental income for the quarter and six months ended June 30, 2005, include $2.2 and $4.4 million,  respectively,  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 the date of the amendment
     forward.  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 new lawsuit  against us seeking to prevent our  termination of the amended lease.  On November 9,
     2004, after a hearing, the court denied HealthSouth's request for a preliminary injunction to prevent the lease termination. We
     are current Our lease with HealthSouth requires that, after termination, HealthSouth manage the hospitals for our account for a
     management  fee during the period of the  transition  to a new tenant and remit the net cash flow to us. During the pendency of
     these  disputes,  HealthSouth  has  continued to pay us at the disputed  rent amount and we have applied the payments  received
     against the net cash flow due,  but we do not know how long  HealthSouth  may  continue  to make  payments.  On June 27,  2005,
     HealthSouth  filed at the SEC restated  financial data for periods ending December 31, 2003, which show a substantial  negative
     net worth and a history of substantial  operating losses. We have been unable to obtain reliable current financial  information
     about the operations of HealthSouth or our hospitals.  Legal expenses  related to this matter were  approximately  $500,000 and
     $900,000,  respectively,  for the quarter and six months ended June 30, 2005 and $0 and $50,000,  respectively, for the quarter
     and six months ended June 30, 2004, and are included in general and administrative expenses.
(2)  Included in Other Income for the six months ended June 30, 2004 is $1.25 million  received in a settlement  of litigation  with
     Marriott International, Inc.
(3)  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.
(4)  Includes deferred percentage rent (see Note 1 on pages 13 and 14).
(5)  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)  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  net income,
                    our calculation of EBITDA for the first three quarters  includes  estimated
                    amounts  with  respect  to  those   periods.   The  fourth  quarter  EBITDA
                    calculation   excludes  the  amounts  recognized  during  the  first  three
                    quarters.

                    We  compute  EBITDA as income  from  continuing  operations  plus  interest
                    expense,  depreciation  expense and deferred  percentage  rent. 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)  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  net income,
                    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.

               (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.


                    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 1 above.  We consider  FFO to be an  appropriate
                    measure of performance for a real estate  investment  trust, or 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
                    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.  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)  Amounts are before depreciation, but after impairment write downs.
(2)  Properties where the majority of units are independent living apartments are classified as independent living communities.
(3)  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 the date of the amendment  forward.  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 new lawsuit  against us seeking to
     prevent our termination of the amended lease. On November 9, 2004, after a hearing, the court denied HealthSouth's  request for
     a preliminary  injunction to prevent the lease termination.  We are currently seeking an expedited judicial  determination that
     the lease  termination was valid and we are pursuing  damages  against  HealthSouth in the lawsuit which we brought in 2003. We
     have also begun work to identify and qualify a new tenant operator for the hospitals. Our lease with HealthSouth requires that,
     after termination, HealthSouth manage the hospitals for our account for a management fee during the period of the transition to
     a new tenant and remit the net cash flow to us. During the pendency of these  disputes,  HealthSouth has continued to pay us at
     the disputed rent amount and we have applied the payments  received  against the net cash flow due, but we do not know how long
     HealthSouth may continue to make payments.  On June 27, 2005,  HealthSouth filed at the SEC restated financial data for periods
     ending December 31, 2003, which show a substantial  negative net worth and a history of substantial  operating  losses. We have
     been unable to obtain reliable current financial information about the operations of HealthSouth or our hospitals.
(4)  These 31 properties  are leased to Five Star Quality Care,  Inc., or Five Star,  and 30 are managed by Sunrise  Senior  Living,
     Inc., or Sunrise. Sunrise does not guaranty Five Star's lease obligations.
(5)  Marriott International, Inc., or Marriott, guarantees the lease for the 14 properties leased to Sunrise.
(6)  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.

(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 the date of the amendment  forward.
     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 new lawsuit against us seeking
     to prevent our termination of the amended lease. On November 9, 2004, after
     a  hearing,  the  court  denied  HealthSouth's  request  for a  preliminary
     injunction to prevent the lease  termination.  We are currently  seeking an
     expedited  judicial  determination that the lease termination was valid and
     we are pursuing damages against HealthSouth in the lawsuit which we brought
     in 2003.  We have also  begun  work to  identify  and  qualify a new tenant
     operator for the hospitals. Our lease with HealthSouth requires that, after
     termination,  HealthSouth  manage  the  hospitals  for  our  account  for a
     management  fee  during the  period of the  transition  to a new tenant and
     remit the net cash  flow to us.  During  the  pendency  of these  disputes,
     HealthSouth has continued to pay us at the disputed rent amount and we have
     applied the payments  received against the net cash flow due, but we do not
     know how long HealthSouth may continue to make payments.  On June 27, 2005,
     HealthSouth  filed at the SEC restated  financial  data for periods  ending
     December  31,  2003,  which  show a  substantial  negative  net worth and a
     history of  substantial  operating  losses.  We have been  unable to obtain
     reliable current financial  information about the operations of HealthSouth
     or our hospitals.
