                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

Note 1.  Organization

Senior Housing Properties Trust (together with its subsidiaries, the "Company"),
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 the Company  (13,190,763  shares) to
HRPT  shareholders.  At June 30, 2001,  the Company  owned 86  properties  in 23
states.  Of these properties,  28 were leased to third party operators,  56 were
operated for the Company's account and two properties were 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 from July 1, 2000 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. The Company 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 June 30, 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  for  annual  rent of $1.5  million.  As part of the
Company's  settlement with IHS described in Note 3 above,  IHS remained a tenant
for one property for 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 July 31, 2001, both Multicare and IHS are current on
their rent obligations to the Company.

Note 7.  Unrealized Gain on Investment

As of June 30, 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  sheets  represents  the  difference  between  their market
prices on the date they were received ($6.50 per share) and the market values on
the dates of these balance sheets.

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
three and six months ended

Note 9.  Indebtedness

The Company has a $270 million,  interest only,  revolving,  secured bank credit
facility.  The credit  facility  matures in September 2002. The interest rate is
LIBOR plus a premium (5.87% at June 30, 2001).  The credit facility is available
for acquisitions,  working capital and for general business purposes. As of June
30, 2001, $74 million was outstanding and $196 million was available for drawing
under the credit facility.

Note 10. Manditorily Redeemable Preferred Securities of a Subsidiary Trust Whose
Sole Assets are the Company's Junior Subordinated Debentures Due 2041

In June  2001,  SNH  Capital  Trust I (the  "Issuer"),  a  wholly-owned  finance
subsidiary of the Company,  issued 1,000,000 shares of 10.125%  quarterly income
preferred  securities  (the "Trust  Preferred  Securities"),  with a liquidation
preference of $25 per share, for a total liquidation amount of $25 million.  The
Trust Preferred  Securities represent an undivided beneficial ownership interest
in the assets of the Issuer. Proceeds from the issuance of the

                                       7

                         SENIOR HOUSING PROPERTIES TRUST
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
                                   (Unaudited)


Trust  Preferred  Securities  were used to acquire  10.125% junior  subordinated
debentures  (the  "Debentures")  due June 15,  2041 issued by the  Company.  The
Issuer exists solely to issue the Trust Preferred  Securities and its own common
securities and acquire and hold the Debentures,  which are its sole assets.  The
Company owns all of the common  securities of the Issuer.  The net proceeds from
the sale of the Trust  Preferred  Securities and the Debentures  were applied to
reduce the Company's  outstanding  obligations  under its revolving  bank credit
facility.  The  underwriting  commissions  and other costs will be deferred  and
amortized  over  the 40 year  life of the  Trust  Preferred  Securities  and the
Debentures.  The Company can redeem the Debentures for their  liquidation  value
before the  maturity in whole or in part on or after June 15,  2006.  The Issuer
will  redeem  all  of  the  outstanding  Trust  Preferred  Securities  when  the
Debentures  are repaid at  maturity.  In  addition,  if the Company  redeems any
Debentures  before their  maturity,  the Issuer will use the cash it receives on
the redemption of the Debentures to redeem, on a proportionate  basis, the Trust
Preferred Securities and its common securities.

The Company has guaranteed the payments of distributions, redemption amounts and
liquidation  payments due on the Trust  Preferred  Securities  to the extent the
Issuer has funds available for the payments (the  "Guarantee").  The obligations
of the Company under the Guarantee are  subordinate  to its  obligations  to its
other  creditors  to the same  extent as the  Debentures.  The  Trust  Preferred
Securities  are  shown as  "Mandatorily  Redeemable  Preferred  Securities  of a
Subsidiary  Trust Whose Sole Assets are the Junior  Subordinated  Debentures Due
2041" in the Company's  consolidated  balance sheets. The Company's  obligations
relating to the Trust Preferred  Securities include obligations to make payments
on  the  Debentures  and  obligations  under  the  related  junior  subordinated
indenture (as  supplemented by the supplemental  indenture) of the Company,  the
Guarantee  and the amended and restated  trust  agreement  of the Issuer.  Taken
together,  these  obligations  represent a full and  unconditional  guarantee of
amounts under the Trust Preferred Securities.

Note 11.  Shareholders' Equity

The Company has reserved  1,300,000  shares of the Company's common shares under
the terms of the 1999  Incentive  Share  Award Plan (the "Award  Plan").  In May
2001,  the three  Independent  Trustees,  as part of their annual fee, were each
granted  500 common  shares  under the Award  Plan . The  shares  granted to the
Independent  Trustees vested  immediately.  The grants were made pursuant to the
exemption from  registration  contained in Section 4(2) of the Securities Act of
1933, as amended.  At June 30, 2001,  1,295,500 of the  Company's  common shares
remain reserved for issuance under the Award Plan.

On May 20, 2001, the Company paid a distribution  to  shareholders  of $0.30 per
share, or $7.8 million.

Note 12.  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
June 30, 2001, approximately $6.7 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.  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


                                       8


                         SENIOR HOUSING PROPERTIES TRUST
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
                                   (Unaudited)

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
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 suffer adverse financial consequences.

Note 13.  Subsequent Events

On July 3 and July 11,  2001,  the Company  issued a total of  3,445,000  common
shares  of  beneficial  interest,  for gross  proceeds  of  approximately  $44.8
million.  The proceeds  received net of  underwriting  commissions  and costs of
issuance  of $2.5  million  were  applied  to reduce the  Company's  outstanding
obligations under its revolving credit facility.

On July 9, 2001, the Company declared a distribution of $0.30 per share, or $7.8
million, which will be paid to shareholders on or about August 21, 2001.

On July 10, 2001, pursuant to the Award Plan, the Company's officers and certain
key  employees  of the  Company's  advisor,  REIT  Management  & Research  Inc.,
received grants aggregating 12,100 common shares valued at $13.02 per share, the
closing  price of the common  shares on the New York Stock  Exchange on July 10,
2001. The grants were made pursuant to the exemption from registration contained
in Section 4(2) of the Securities Act of 1933, as amended.

On July 11, 2001,  the Issuer sold 95,750 Trust  Preferred  Securities  for $2.4
million which was invested in Company  Debentures  pursuant to the underwriters'
exercise of an  over-allotment  option  which had been  granted  pursuant to the
transaction described in Note 10 above.

On July 12, 2001, the Company obtained mortgage  financing secured by two of its
properties in Michigan,  which are operated for the Company's own account, for a
total of $9.1  million.  The  mortgages  require  interest to be paid monthly at
prime less a discount.  These mortgages mature in July 2002, but the Company has
an option to extend these mortgages for an additional 12 months.

On August 9, the  Company  entered an  agreement  to  acquire  31 senior  living
communities from Crestline Capital  Corporation for approximately  $600 million.
These  communities   contain  7,487  living  units,  a  majority  of  which  are
independent living  apartments.  All of these communities are managed under long
term contracts by Marriott  International,  Inc.  Because these  communities are
managed by, but not leased to, Marriott,  the Company announced its intention to
identify or create a tenant  entity in order to maintain  its REIT status  under
applicable  IRS rules.  The closing of this  acquisition is expected to occur in
early 2002.

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 and six months ended June 30, 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 June 30, 2001, Compared to Three Months Ended June 30, 2000

The  increases in total  revenues and total  expenses for the three months ended
June 30, 2001,  compared to the three months ended June 30, 2000,  are primarily
the result of the accounting for facilities'  operations which,  during the 2001
period were  operated for our  account.  During the second  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 June 30,  2001,  compared to the three months ended
June 30, 2000, rental income decreased to $11.1 million from $18.2 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 $2.1  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 $208,000  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 our
bankrupt former tenants.  Recurring general and administrative expense decreased
by  $365,000  primarily  due to the  impact of the sale of  properties  in 2000.
During  the  second  quarter  of 2001,  we  incurred  nonrecurring  general  and
administrative costs totaling  approximately $2.2 million in connection with the
establishment of operating systems for foreclosed  properties.  Similar types of
start-up charges are not expected hereafter.

With regard to facilities'  operations,  there are no comparative results to the
second 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
first  quarter of 2001 and the fourth  quarter of 2000 by $143,000 and $227,000,
respectively.  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):

The  decreases  in net patient  revenues  and  patient  operating  expenses  are
primarily  due to the closing of one nursing  home during the fourth  quarter of
2000 and one nursing home at the end of the first quarter of 2001.

Net income was $2.8 million ($0.11 per share) in the three months ended June 30,
2001,  as compared to $7.3  million  ($0.28 per share) in the three months ended
June 30, 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 June 30, 2001, was $10.8 million  compared to $14
million for the same period in 2000.  The decrease of $3.2 million is due to the
factors  discussed above.  Cash flows provided by operating  activities and cash
available for  distribution  may not necessarily  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.

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

Six Months Ended June 30, 2001, Compared to Six Months Ended June 30, 2000

The increases in total revenues and total expenses for the six months ended June
30,  2001,  compared to the six months ended June 30, 2000,  are  primarily  the
result of the accounting for facilities'  operations which were operated for our
account  during the 2001  period.  During the first half of 2000,  we owned only
properties leased to third parties and mortgage investments and therefore we had
only rental and interest  income and expenses  related to  investments in leased
and mortgaged properties.

For the six months  ended June 30,  2001,  compared to the six months ended June
30, 2000,  rental  income  decreased to $22.2 million from $36.3  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 $4.4  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 $641,000  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  in the
settlement   with  our   bankrupt   former   tenants.   Recurring   general  and
administrative  expense decreased by $707,000 primarily due to the impact of the
sale of  properties  in 2000.  During the first six months of 2001,  we incurred
nonrecurring  general and  administrative  costs totaling  approximately $4.2 in
connection  with  the   establishment   of  operating   systems  for  foreclosed
properties;  similar types of  facilities  operations  start-up  charges are not
expected hereafter.

Net income was $5.6  million  ($0.22 per share) in the six months ended June 30,
2001,  as compared to $14.8  million  ($0.57 per share) in the six months  ended
June 30, 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 six months  ended June 30, 2001,  was $21 million  compared to $27.4
million for the same period in 2000.  The decrease of $6.4 million is due to the
factors  discussed above.  Cash flows provided by operating  activities and cash
available  for  distribution  may not  necessarily  equal funds from  operations
because  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  (5.87% per annum at June 30,  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 June 30, 2001,
there was $74 million drawn under this  facility and $196 million  available for
borrowing. At August 1, 2001 there was $29 million drawn under this facility and
$241 million was available for borrowing.

On May 21, 2001, our shelf registration statement for the issuance of up to $500
million of equity and debt  securities  was  declared  effective  by the SEC. An
effective shelf  registration  enables us to raise capital on an expedited basis
by filing a prospectus  supplement with the SEC. At August 1, 2001, $428 million
was available to be used under this effective shelf registration statement.

In June 2001,  SNH Capital  Trust I, a  wholly-owned  finance  subsidiary of the
Company,   issued  1,000,000  shares  of  10.125%   quarterly  income  preferred
securities  with  a  liquidation  preference  of  $25  per  share,  for a  total
liquidation  amount of $25  million.  An  additional  95,750 of these  preferred
securities  were  issued in July  2001,  to cover  over-allotments,  for a total
liquidation  value of  approximately  $2.4  million.  The  preferred  securities
represent  an  undivided  beneficial  ownership  interest  in the  assets of SNH
Capital Trust I. Proceeds  from the issuance of the  preferred  securities  were
used to acquire our 10.125%  junior  subordinated  debentures due June 15, 2041.
SNH Capital Trust I exists solely to issue the preferred  securities and its own
common securities and acquire and hold the

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


debentures, which are its only assets. We used the net proceeds from the sale of
the  debentures to repay some of our debt  outstanding  under our revolving bank
credit facility.

Subsequent  to June 30, 2001,  we issued  3,445,000  common shares of beneficial
interest,  raising  net  proceeds  of  approximately  $42.3  million.  These net
proceeds  received  were used to repay  some of our debt  outstanding  under our
revolving credit facility.

Subsequent  to June 30,  2001,  we obtained  mortgage  financing of $9.1 million
secured by two of our  properties  in  Michigan,  which are operated for our own
account.  The  mortgages  require  interest  to be paid  monthly at prime less a
discount.  These mortgages mature in July 2002, but we have the option to extend
these mortgages for an additional 12 months.

On August 9, 2001, we entered an agreement with Crestline Capital Corporation to
acquire all of the capital stock of a Crestline  subsidiary which owns 31 senior
living  communities with 7,487 living units. The purchase price is approximately
$600 million and this acquisition is expected to close in early 2002.  Available
funding for this acquisition has been identified as follows:  approximately $235
million of existing  Crestline debt which may be assumed;  about $150 million of
new  indebtedness  to be placed by  Crestline  before  closing  and which we may
assume at closing;  and the balance by drawings  under our existing  bank credit
facility.  We also have the  option to pay up to $25  million  of this  purchase
price with an  unsecured,  two year note to Crestline at 10% per annum.  Some of
the  Crestline  debt which we will assume,  the note to  Crestline  and our bank
credit facility may be prepaid. Although we believe we have identified available
capital  sufficient to fund this acquisition,  we are now considering  financing
alternatives  which may provide longer term capital for this purchase;  and some
alternative  long term capital may be raised before or after this acquisition is
closed.

At June 30, 2001, we had cash and cash equivalents of $5.6 million.  For the six
months ended June 30, 2001 and 2000:  cash provided by operating  activities was
$14.8  million  and $22.9  million,  respectively;  cash (used for)  provided by
investing  activities was $(2.5) million and $12.2  million,  respectively;  and
cash  used for  financing  activities  was  $14.4  million  and  $41.4  million,
respectively.  The working capital  required for our  operations,  including our
facilities'  operations,  has been  provided by our  operations  and by drawings
under  our bank  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 June 30, 2001,  which we will pay on or
about August 21, 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,

                                       13

                         SENIOR HOUSING PROPERTIES TRUST

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

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
noticeable.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market  changes in interest  rates.  We manage our exposure to
this market risk through our monitoring of available financing alternatives. Our
strategy  to manage  exposure  to changes in interest  rates is  unchanged  from
December 31, 2000. Furthermore, we do not foresee any significant changes in our
exposure to fluctuations in interest rates or in how this exposure is managed in
the near  future.  At June 30, 2001,  we had $25 million of the Trust  Preferred
Securities  outstanding,  the dividends of which are  dependent  upon our making
required  payments on our 10.125%  junior  subordinated  debentures due 2041. No
principal repayments are due on the debentures until maturity. If the debentures
were to be refinanced at interest rates which are one  percentage  point higher,
our per annum interest cost would increase $250,000.

Our trust  preferred  securities  are listed on the New York Stock  Exchange and
their market value is principally  determined by supply and demand factors.  The
market price, if any, of our debentures as of June 30, 2001, may be sensitive to
changes in interest rates.  Typically, if market rates of interest increase, the
current market price of a fixed rate  obligation will decrease.  Conversely,  if
market  rates of interest  decrease,  the current  market  price of a fixed rate
obligation will typically increase. Based on the balance outstanding at June 30,
2001, and discounted cash flow analysis, a hypothetical immediate one percentage
point change in interest rates would change the fair value of $25 million of our
fixed rate debentures by approximately $2.2 million.

Our debentures have provisions that allow us to make repayments earlier than the
stated maturity date. These  prepayment  rights may afford us the opportunity to
mitigate the risk of  refinancing  at maturity at high rates by  refinancing  at
lower rates prior to maturity.  Our ability to prepay the debentures at par will
also effect the change in the fair value of the  debentures  which would  result
from a change in interest rates.

Because interest on our revolving credit facility is at a floating rate, changes
in interest  rates will not affect the value of our revolving  credit  facility.
However,  changes in  interest  rates will  affect our  operating  results.  For
example,  the interest  rate  payable on our  revolving  credit  facility of $74
million at June 30, 2001,  was 5.87% per annum,  and an immediate  10% change in
that interest  rate, or 58.7 basis points,  would increase or decrease our costs
by approximately $434,380, or $0.02 per share annually:

                        Interest Rate       Outstanding          Total Interest
                           Per Year            Debt             Expense Per Year
                        -------------       -----------         ----------------
At June 30, 2001              5.87%            $74,000              $4,344
10% reduction                 5.28%            $74,000              $3,907
10% increase                  6.46%            $74,000              $4,780

The foregoing table presents a so-called  "shock"  analysis,  which assumes that
the interest rate change by 10%, or 58.7 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.  All of our floating rate borrowings  under our bank
revolver  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.
