Note 1.  Organization

Senior  Housing  Properties  Trust  ("Senior  Housing"),  a Maryland real estate
investment trust, was organized on December 16, 1998, as a 100% owned subsidiary
of HRPT Properties Trust ("HRPT").  On October 12, 1999, HRPT distributed  50.7%
of its  ownership  in Senior  Housing to HRPT  shareholders.  At March 31, 2001,
Senior  Housing  and its  subsidiaries  (collectively  the  "Company")  owned 86
properties  in 23 states.  Of these  properties,  28 were  leased to third party
operators,  57 were  operated  for the  Company's  account and one  property was
closed.

Note 2.  Interim Financial Statements

These  quarterly  financial  statements  have been prepared in  accordance  with
generally accepted accounting  principles for interim financial  information and
with  the   instructions  to  Form  10-Q  and  Rule  10-01  of  Regulation  S-X.
Accordingly,  they do not include all of the information and footnotes  required
by generally accepted  accounting  principles for complete financial  statements
and  should  be read in  conjunction  with the  audited  consolidated  financial
statements for the year ended  December 31, 2000,  included in the Annual Report
on Form 10-K. In the opinion of management, all adjustments considered necessary
for a fair  presentation  have been  included.  Operating  results  for  interim
periods are not  necessarily  indicative of the results that may be expected for
the full year. The balance sheet at December 31, 2000, has been derived from the
December 31, 2000, audited financial statement.

Note 3.  Summary of Significant Accounting Policies

BASIS OF PRESENTATION. In January and February 2000, two of the Company's larger
tenants,  Mariner  Post-Acute  Network,  Inc.  ("Mariner") and Integrated Health
Services,  Inc. ("IHS"), filed for bankruptcy.  During 2000, the Company entered
settlements with these tenants pursuant to which the operations of nursing homes
were transferred  from Mariner and IHS to the Company.  Although the settlements
as approved by the Bankruptcy Courts in the Mariner and IHS cases have financial
effect as of July 1, 2000, the  implementation  of these settlements was subject
to material  conditions  subsequent,  including the Company's  obtaining  health
regulatory  licenses and Medicare and Medicaid provider  contracts  necessary to
operate these nursing  homes.  Because the majority of the licenses and provider
contracts had not been received prior to December 31, 2000, the Company reported
the  results  of these  nursing  home  operations  using  the  equity  method of
accounting  through December 31, 2000. Working capital invested in these nursing
home operations was included in Net Investment in Facilities'  Operations in the
Company's  Consolidated  Balance  Sheets and net income from these nursing homes
was  reported  as  Other  Real  Estate  Income  in  the  Company's  Consolidated
Statements of Income.

During the first quarter of 2001, the Company obtained  substantially all of the
healthcare  regulatory  licenses and Medicare and Medicaid  provider  agreements
necessary  for  these  nursing  home   operations.   Accordingly,   the  Company
consolidated  the  nursing  home  operations  effective  January 1,  2001.  On a
proforma basis,  assuming the nursing home operations had been consolidated with
the  Company's  other  subsidiaries  as of December 31, 2000,  the  consolidated
comparative balance sheets would have been (dollars in thousands):

EARNINGS  PER COMMON  SHARE.  Earnings  per common  share is computed  using the
weighted average number of shares outstanding during the period.  Senior Housing
has no common share equivalents,  instruments  convertible into common shares or
other dilutive instruments.

NEW  ACCOUNTING  PRONOUNCEMENTS.  In June  1998 and  June  2000,  the  Financial
Accounting  Standards  Board  issued SFAS No. 133,  "Accounting  for  Derivative
Instruments and Hedging Activities" ("FAS 133") and SFAS No. 138 "Accounting for
Certain  Derivative  Instruments and Hedging  Activities" ("FAS 138"), which are
effective  for fiscal  years  beginning  after June 15, 2000.  These  statements
require  companies  to  record  derivatives  on the  balance  sheet as assets or
liabilities,  measured at fair value.  Gains or losses resulting from changes in
the values of those  derivatives will be reported in the statement of operations
or as a deferred item,  depending on the use of the derivatives and whether they
qualify for hedge accounting. The key criterion for hedge accounting is that the
derivative  must be highly  effective  in achieving  offsetting  changes in fair
value or cash flows of the hedged items during the term of the hedge.  Effective
January 1, 2001,  the Company  adopted the  provisions of FAS 133, as amended by
FAS 138.  As  required  by its  revolving  bank  credit  facility,  the  Company
purchased an interest rate cap agreement on its current debt. At March 31, 2001,
the  value of the  agreement  was zero  and the  adoption  of FAS 133 has had no
effect on the Company's financial statements.

RECLASSIFICATIONS.   Reclassifications  have  been  made  to  the  prior  years'
financial statements to conform to the current year's presentation.

Note 5.  Tenant Default

The Company  previously  leased a nursing facility to Sun Healthcare Group, Inc.
("Sun"),  which was subleased to a regional  operator in Washington  State.  Sun
filed for  bankruptcy in October 1999.  Sun and this subtenant both defaulted on
their  rental  obligations  to the  Company.  The  Company  entered  a new lease
directly with the regional operator during the second quarter of 2001, effective
as of March 1,  2001.  The new lease  arrangement  with this  regional  operator
requires that accumulated rental arrearages be paid over two years with interest
and that current rent be paid at the rate of approximately $800,000 per year.

Note 6.  Bankrupt Tenants

On June 22, 2000,  Multicare,  Inc., a  non-consolidated  subsidiary  of Genesis
Health Ventures, Inc. ("Multicare"),  filed for bankruptcy. Multicare leases one
property  from the  Company  and the  annual  rent  from this  property  is $1.5
million. As part of the Company's settlement with IHS described in Note 3 above,
IHS  remained a tenant for one property at annual rent of $1.2  million.  IHS is
currently  in  bankruptcy  proceedings  and  the  continuation  of  this  rental
arrangement  has been approved by the  Bankruptcy  Court.  As of April 30, 2001,
both Multicare and IHS are current on their rent obligations to the Company.

Note 7.  Unrealized Gain on Investment

As of March 31, 2001,  the Company owned one million HRPT common  shares,  which
are  carried  at fair  market  value in Other  Assets.  The  Unrealized  Gain On
Investment  shown on the balance sheet  represents the difference  between their
market  prices on the date they were  received  from a former  tenant ($6.50 per
share) and on March 31, 2001 ($8.28 per share).

Note 8.  Segment Information

As a result of  transactions  with  bankrupt  former  tenants and the  Company's
receipt of the  applicable  licenses  and  contracts  to operate the  facilities
discussed in Note 3, the Company now has two  reportable  segments;  leasing and
facility operations.  Revenues of the leasing activities are derived from rental
agreements for properties  that are triple net leased to third party  operators.
Revenues of the  facility  operations  are  derived  from  services  provided to
patients  at the  healthcare  facilities  operated  for the  Company's  account.
Performance  is  measured  based on the  return on  investments  for the  leased
properties  and on  contribution  margin  of  the  facilities'  operations.  The
following  table is a summary  of these  reportable  segments  as of and for the
period ended

months ended March 31, 2000, a comparative  table is not  presented  (dollars in

Note 9.  Indebtedness

The Company has a $270 million,  interest only,  revolving,  secured bank credit
facility. The credit facility matures in 2002. The interest rate is LIBOR plus a
premium  (7.17% at March  31,  2001).  The  credit  facility  is  available  for
acquisitions, working capital and for general business purposes. As of March 31,
2001,  $105 million was  outstanding  and $165 million was available for drawing
under the credit facility.

Note 10.  Shareholders' Equity

On January 24, 2001, the Company paid a distribution  to  shareholders  of $0.30
per  share,  or  $7.8  million.  On  April  3,  2001,  the  Company  declared  a
distribution  of  $0.30  per  share,  or  $7.8  million,  which  will be paid to
shareholders on or about May 20, 2001.

Note 11.  Contingencies

A substantial majority of the revenues at the nursing homes now operated for the
Company's account is received from the Federal Medicare program and from various
state Medicaid  programs.  Until the Company received the required  licenses and
contracts  to operate  these  nursing  homes,  billings  for  patients  at these
facilities were made through Mariner and IHS as licensees,  respectively.  As of
March 31, 2001, approximately $19 million received by IHS and Mariner since July
1, 2000,  which is due to the Company is included on the Company's  Consolidated
Balance Sheets in Accounts Receivable.  At May 10, 2001, a receivable balance of
approximately  $14  million  remained  due from  IHS and  Mariner.  The  Company
believes  these  funds  will be paid  by  Mariner  and  IHS  pursuant  to  their
contractual  obligations  approved by the Bankruptcy  Courts.  However,  IHS and
Mariner  remain in bankruptcy  proceedings  and their record keeping and payment
processing has not always been timely.

Eight nursing homes  delivered to the Company by IHS in 2000 were not previously
owned or mortgaged by the Company.  These  properties  were  transferred  to the
Company  by IHS as  partial  compensation  for its  defaults  under  leases  and
mortgages.  Because these  properties were not owned or mortgaged by the Company
they do not constitute  foreclosure property under Internal Revenue Code ("IRC")
provisions  which permit  REITs to operate  nursing  homes.  To comply with laws
applicable  to  REITs,   these  nursing  homes  were  operated  during  2000  by
corporations   which  were  99%  beneficially   owned  by  the  Company  and  1%
beneficially  owned by the  Company's  Managing  Trustees,  Barry M. Portnoy and
Gerard  M.  Martin,  who  also  controlled  100% of the  voting  power  of these
corporations.  On January 1, 2001, the laws concerning the Company's  ability to
own and operate these

properties  changed  and the Company  purchased  Messrs.  Portnoy  and  Martin's
ownership  interests in these entities.  The Company has applied for an Internal
Revenue  Service  ruling in order to clarify its  ability to continue  operating
these properties which were received as compensation for losses it suffered as a
result of IHS'  bankruptcy.  If this revenue  ruling is denied,  the Company may
have  to  lease  or  sell  these  properties  with  possible  adverse  financial
consequences.

Under  IRC laws  applicable  to REITs,  after a 90 day  transition  period,  the
Company is  required to engage a third  party  contractor  to manage the nursing
home  operations  which it acquired from Mariner and IHS.  Also,  under IRC laws
applicable to REITs, the Company may continue to operate nursing homes which are
categorized  as  "foreclosure  properties"  for up to three  years  (subject  to
extensions in certain circumstances).  Messrs. Martin and Portnoy organized Five
Star Quality Care, Inc.  ("Five Star") to serve as an independent  contractor to
operate  nursing  homes for the  Company.  If Five  Star is  unable to  continue
managing  these  nursing  homes,  the  Company may be unable to find a qualified
operator   to  assume   these   management   responsibilities,   and,  in  those
circumstances, the Company may lose its IRC status as a REIT or otherwise suffer
adverse financial  consequences.  Similarly, if the Company is unable to sell or
lease these  properties to a financially  qualified  operator within  applicable
time  periods,  the Company may cease to be a REIT or otherwise  suffer  adverse
financial consequences.

Item 2.  Management's Discussion and Analysis of Financial Condition and
         Results of Operations

The following  discussion  presents an analysis of our results of operations for
the three  months  ended  March  31,  2001 and 2000.  This  discussion  includes
references  to Funds from  Operations  ("FFO").  FFO is net income  computed  in
accordance  with  Generally  Accepted  Accounting  Principles  ("GAAP"),  before
extraordinary  and  non-recurring  items, plus depreciation and amortization and
expected  percentage  rents.  We consider  FFO to be an  appropriate  measure of
performance for an equity REIT, along with cash flow from operating  activities,
financing  activities and investing  activities,  because it provides  investors
with an indication of an equity REIT's  ability to incur and service debt,  make
capital  expenditures,  pay  distributions and fund other cash needs. The way we
calculate  FFO may not be  comparable to FFO reported by other REITs that define
the term differently.  For example,  we do not include proceeds of land sales in
FFO  although  some  REITs do,  and we add  expected  percentage  rent to FFO in
certain  periods  although  some  REITs  do not.  FFO does  not  represent  cash
generated  by operating  activities  in  accordance  with GAAP and should not be
considered as an alternative to net income,  determined in accordance with GAAP,
as an  indication  of  financial  performance  or the cash flow  from  operating
activities, determined in accordance with GAAP, as a measure of liquidity.

RESULTS OF OPERATIONS

Three Months Ended March 31, 2001, Compared to Three Months Ended March 31, 2000

The  increases in total  revenues and total  expenses for the three months ended
March 31, 2001, compared to the three months ended March 31, 2000, are primarily
the result of the required account for facilities'  operations which, during the
2001 period were operated for our account.  During the first quarter of 2000, we
owned only  properties  leased to third  parties and  mortgage  investments  and
therefore  we only had  rental  and  interest  income  and  expenses  related to
investments in leased and mortgaged properties.

For the three months  ended March 31,  2001,  compared to the three months ended
March 31, 2000,  rental income  decreased to $11.1  million from $18.1  million.
This decrease is primarily  due to the sale of seven  properties in 2000 and the
tenant  bankruptcies and the settlements  which  terminated  leases and assigned
operations to us or our nominees.

Interest  expense was $2.3  million  lower in 2001  compared to 2000 because the
average  balance  outstanding  and the weighted  average  interest  rates on our
credit  facility  were  lower  during  the  2001  period.  Depreciation  expense
decreased  in 2001 by $443,000  due to the sale of seven  properties  in 2000, a
reduction in asset values as a result of impairment  losses recorded in 2000 and
the net effect of the assets  disposed  of versus the assets  acquired  from the
settlement  agreements with our bankrupt former tenants.  Recurring  general and
administrative  expense decreased by $342,000 primarily due to the impact of the
sale of properties in 2000.  During 2001, we incurred  nonrecurring  general and
administrative  costs totaling  approximately  $2 million in connection with the
establishment of operating systems for foreclosed  properties.  Similar types of
start-up charges are expected in the second quarter of 2001, but are expected to
materially decline thereafter.

With regard to facilities'  operations,  there are no comparative results to the
first quarter of 2000 since no facilities  were operated for our account  during
the earlier period. However, our net operating income, calculated as Facilities'
Operations Revenues less Facilities'  Operations Expenses has increased from the
fourth  quarter  of 2000 by  $84,000.  In the fourth  quarter  of 2000,  our net
operating  income was  presented  as Other Real Estate  Income.  The table below
shows these comparable results of the operations (dollars in thousands):

                                                    Three Months Ended

                                     ----------------     --------------------
Facilities' operations revenues         $57,354                $58,944
Facilities' operations expenses          55,978                 57,652

                                     ================     ====================


The  decreases  in net patient  revenues  and  patient  operating  expenses  are
primarily  due to there being two less days of  operations  for the three months
ended March 31, 2001,  as compared to the three  months ended  December 31, 2000
and the closure of one nursing home during the fourth quarter of 2000.

Net income was $2.8  million  ($0.11 per share) in the three  months ended March
31,  2001,  as compared to $7.6  million  ($0.29 per share) in the three  months
ended March 31, 2000.  This decrease in net income is primarily the  consequence
of the changes in revenues and expenses resulting from the tenant  bankruptcies,
settlements and sales of properties in 2000.

FFO for the three months ended March 31, 2001, was $10.3  million,  or $0.40 per
share,  compared to $13.3  million,  or $0.51 per share,  for the same period in
2000.  The  decrease  of $3 million,  or $0.11 per share,  is due to the factors
discussed above. Cash flows provided by operating  activities and cash available
for distribution may not necessarily

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations (continued)

equal funds from  operations  as cash flows are affected by factors not included
in the  funds  from  operations  calculation,  such as  changes  in  assets  and
liabilities.

LIQUIDITY AND CAPITAL RESOURCES

We have a $270 million, interest only, secured,  revolving bank credit facility.
The interest  rate is LIBOR plus a premium  (7.17% per annum at March 31, 2001).
The credit  facility is  available  for  acquisitions,  working  capital and for
general business purposes. We have the ability to repay and redraw amounts under
this credit  facility  until its maturity in September  2002. At March 31, 2001,
there was $105 million drawn under this facility and $165 million  available for
borrowing.

On May 7, 2001, we filed a shelf  registration  statement for the issuance of up
to $500 million of equity and debt securities.  When this becomes effective,  we
may be able to raise capital on an expedited basis in the future.

At March 31, 2001, we had cash and cash  equivalents of $13.7  million.  For the
three  months  ended  March  31,  2001 and  2000:  cash  provided  by  operating
activities  was $6.7 million and $11.2  million,  respectively;  cash (used for)
provided by investing activities was ($893,000) and $12.2 million, respectively;
and cash  provided by (used for)  financing  activities  was $225,000 and ($27.6
million),  respectively.  The  working  capital  required  for  our  operations,
including  facilities' operations,  has been provided by our  operations  and by
drawings  under our credit  facility.  We believe  that our current  cash,  cash
equivalents,  future cash from operating  activities and availability  under our
credit facility will be sufficient to meet our short-term and long-term  capital
requirements,  including the  distribution to  shareholders of $7.8 million,  or
$0.30 per share,  for the quarter ended March 31, 2001,  which we will pay on or
about May 20, 2001.

Impact of Inflation

Inflation  might have both  positive  and negative  impacts  upon our  business.
Inflation might cause the value of our real estate  investments to increase.  In
an inflationary environment,  the percentage rents which we receive based upon a
percentage of our tenants'  revenues should increase.  Similarly,  inflation may
tend to  increase  patient  revenues  and  Medicare  and  Medicaid  rates at the
facilities  which are  operated  for our  account.  Offsetting  these  benefits,
inflation might cause our costs of equity and debt capital to increase and wages
and other operating costs at the operated facilities to increase. An increase in
our capital  costs or in our operating  costs will result in decreased  earnings
unless  it is offset by  increased  revenues.  In  periods  of rapid  inflation,
nursing home operating costs usually increase faster than revenues and this fact
has an  adverse  impact  upon  operating  income.  We do not  believe it will be
possible to eliminate the adverse impact of rapid  inflation upon the results of
the facilities'  operations  conducted for our account.  To mitigate the adverse
impact of increased costs of debt capital in the event of material  inflation we
have  purchased  an interest  rate cap  agreement  and we may enter into similar
interest rate hedge arrangements in the future. The decision to enter into these
arrangements  was and will be based on the  amount  of our  floating  rate  debt
outstanding,  our belief that  material  interest  rate  increases are likely to
occur and upon requirements of our borrowing arrangements.

Seasonality

Nursing home operations have historically  reflected modest seasonality.  During
calendar  fourth  quarter  holiday  periods  nursing home patients are sometimes
discharged  to join in family  celebrations  and  admission  decisions are often
deferred.  The first  quarter  of each  calendar  year  usually  coincides  with
increased  illness  among nursing home  residents  which can result in increased
costs or  discharges  to  hospitals.  As a result of these  factors  and others,
nursing home operations  sometimes  produce  greater  earnings in the second and
third quarters of each calendar year and lesser earnings in the fourth and first
calendar  quarters.  We do not expect  these  seasonal  differences  to have any
impact upon the ability of our tenants to pay our rent.  We do not expect  these
seasonal  differences to have a material impact on the financial  results at the
nursing homes operated for our account,  but such seasonable  differences may be
noticed.

                         SENIOR HOUSING PROPERTIES TRUST


Item 3.  Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market changes in interest rates.  Because interest on all our
outstanding  debt is at a  floating  rate,  changes in  interest  rates will not
affect  the value of our  outstanding  debt  instruments.  However,  changes  in
interest rates will affect our operating results. For example, the interest rate
payable on our  outstanding  indebtedness of $105 million at March 31, 2001, was
7.17% per annum.  An immediate 10% change in that  interest  rate, or 71.7 basis
points, would increase or decrease our costs by approximately $756,000, or $0.03
per share per year:

                                                                     Interest

                               Per Year            Debt               Year
                           ---------------    --------------     -------------
At March 31, 2001                7.17%           $105,000            $7,529
10% reduction                    6.45%           $105,000            $6,773
10% increase                     7.89%           $105,000            $8,285

The foregoing table presents a so-called  "shock"  analysis,  which assumes that
the interest rate change by 10%, or 71.7 basis points,  is in effect for a whole
year. If interest rates were to change gradually over one year, the impact would
be less.

We borrow in U.S.  dollars  and all of our  current  borrowings  are  subject to
interest at LIBOR plus a premium.  Accordingly,  we are vulnerable to changes in
U.S. dollar based short-term rates, specifically LIBOR.

During  the  past  year,  short-term  U.S.  dollar  based  interest  rates  have
fluctuated.  We are unable to predict the  direction or amount of interest  rate
changes during the next year. As required by our revolving bank credit facility,
we have  purchased an interest rate cap agreement for a notional  amount of $200
million to protect against LIBOR  increases above 8% through  December 10, 2001.
However,  we may incur additional debt at floating or fixed rates in the future,
which would increase our exposure to market changes in interest rates.
