its existing properties.  In addition, the Company received $9,104 from the full

         During  February  2001 the  Company  redeemed at par all $40,000 of its

Company  redeemed  at par all  $162,000  of its  outstanding  7.50%  convertible
subordinated debentures due October 2003. The redemptions were funded using cash
on hand and proceeds from the preferred  share offering  discussed in Note 6. In
connection with these redemptions,  the Company recognized an extraordinary loss
of $1,817 from the write-off of deferred financing fees.

         In  April  2001  the  Company  entered  into a new  $425,000  unsecured
revolving credit facility (the "New Credit  Facility").  The New Credit Facility
bears interest at LIBOR plus a premium and matures in April 2005. The New Credit
Facility  includes an  accordian  feature  which  allows it to be  expanded,  in
certain  circumstances,  by up to $200,000.  The  Company's  $500,000  unsecured
revolving  credit facility which was scheduled to mature in 2002, was terminated
by the Company in April 2001. In connection with this  termination,  the Company
will recognize an extraordinary loss of approximately $320 from the write-off of

         In  February  2001 the Company  issued  8,000,000  series A  cumulative
redeemable  preferred  shares in a public offering for net proceeds of $193,277.
Each series A preferred share requires dividends of $2.46875 per annum,  payable
in equal  quarterly  payments.  Each series A preferred  share has a liquidation
preference of $25.00 and is redeemable, at the Company's option, for $25.00 plus
accrued and unpaid dividends at any time on or after February 22, 2006. On April
9, 2001,  the Company  announced a  distribution  on these  series A  cumulative
redeemable  preferred shares of $0.5555 per share which will be paid on or about
May 15, 2001, to shareholders of record as of May 1, 2001.

         On April 4, 2001,  the Company  declared a  distribution  on its common
shares with  respect to the quarter  ended March 31,  2001,  of $0.20 per common
share, or approximately  $26,100,  which will be distributed on or about May 25,
2001, to shareholders of record on April 24, 2001.

         The Board of Trustees has authorized the Company to repurchase up to 14
million common shares. During the three months ended March 31, 2001, the Company

Subsequent to March 31, 2001,  through May 10, 2001, the Company  repurchased an

500 common shares under the Company's 1992 Incentive Share Award Plan as part of
their annual fees. The shares awarded to the trustees vest immediately.

         This discussion  includes  references to Funds from Operations ("FFO").
FFO, as defined in the White Paper on Funds From  Operations  which was approved
by the Board of Governors of the National  Association of Real Estate Investment
Trusts  ("NAREIT")  in March 1995 and as  clarified  from time to time,  is "net
income (computed in accordance with generally accepted  accounting  principles),
excluding  gains (or  losses)  from sales of  property,  plus  depreciation  and
amortization,  and after  adjustment for  unconsolidated  partnerships and joint
ventures. Adjustments for unconsolidated partnerships and joint ventures will be
calculated to reflect funds from  operations on the same basis." 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. We compute FFO in accordance with the standards established by
NAREIT  including  adjustments  for our pro  rata  share  of FFO of  Hospitality
Properties  Trust  ("HPT") and Senior  Housing  Properties  Trust  ("SNH"),  but
excluding unusual and non-recurring  items, certain non-cash items, and gains on
sales of undepreciated  properties,  which may not be comparable to FFO reported
by other REITs that define the term  differently.  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, or as a measure of liquidity.

RESULTS OF OPERATIONS

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

         Total revenues for the three months ended March 31, 2001,  decreased to
$99.8  million  from $100.3  million for the three  months ended March 31, 2000.
Rental  income  decreased  in 2001 by $2.7 million and interest and other income
increased in 2001 by $2.3 million,  compared to the prior period.  Rental income
decreased  primarily  because of the sale of three  properties  in 2001 and four
properties  during 2000 and a decline in property  occupancy  to 96% in the 2001
period  from  98% in the  2000  period.  Interest  and  other  income  increased
primarily as a result of higher cash balances invested in 2001 compared to 2000,
resulting  primarily from a preferred share offering  completed in February 2001
and a debt financing completed in December 2000.

         Total expenses for the three months ended March 31, 2001,  decreased to
$75.5  million  from $79.5  million for the three  months  ended March 31, 2000.
Included in total  expenses for the 2001 period is the reversal of an impairment
loss reserve  recorded  during 1999 totaling $4.0  million.  Operating  expenses
increased by $1.2 million primarily as a result of higher utility costs and real
estate  taxes,  offset by a  decrease  in  operating  expenses  from the sale of
properties  during 2000 and 2001.  Interest expense decreased by $899,000 during
2001 compared to the prior year period, as a result of lower average  borrowings
outstanding. Depreciation and amortization increased by $283,000 and general and
administrative  expenses  decreased  by  $604,000.  The  decrease in general and
administrative expenses is due primarily to lower legal and professional fees.

         Equity in earnings of equity investments  decreased by $2.4 million for
the three months ended March 31, 2001,  compared to the same period in 2000. The
decrease is due to lower  earnings  from SNH  resulting  from its  settlement of
tenant bankruptcies and its sale of properties in 2000.

         Net income before preferred  distributions  decreased to $25.8 million,
or $0.20 per common share, for the 2001 period, from $26.5 million, or $0.20 per
common  share,  for the 2000 period.  The change is due primarily to assets sold
during 2000 and the decrease in property  occupancy,  the  write-off of deferred
financing fees  associated with the convertible  subordinated  debentures  which
were repaid during 2001 and the decrease in equity in earnings of SNH, offset by
the reversal of an impairment  loss reserve in 2001 and the increase in interest
earned on financing  proceeds  received in December 2000 and interest  earned on
proceeds of the series A preferred shares issued during February 2001.

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

         FFO for the three months ended March 31, 2001,  was $42.3  million,  or
$0.32 per common share,  and $46.1 million,  or $0.35 per common share,  for the
2000 period. The decrease in FFO is due primarily to assets sold during 2000 and
the  decrease in property  occupancy,  the decrease in equity in earnings of SNH
and dividends on series A preferred  shares,  offset by the increase in interest
earned on larger cash balances.

LIQUIDITY AND CAPITAL RESOURCES

         Total  assets were $2.9  billion at March 31,  2001,  and  December 31,
2000.

         During the three months ended March 31, 2001, we sold three  properties
for net  cash  proceeds  of  $10.4  million.  We also  funded  $7.3  million  of
improvements to our existing  properties and received $9.1 million from the full
repayment  of a real  estate  mortgage  that was secured by two  properties.  In
connection with this repayment,  we reversed an impairment loss reserve recorded
during 1999 of $4.0 million.

         At March 31,  2001,  we owned  12.8  million,  or 49.4%,  of the common
shares of beneficial interest of SNH with a carrying value of $205.5 million and
a market value of $144.4 million, and 4.0 million, or 7.1%, of the common shares
of  beneficial  interest  of HPT with a carrying  value of $105.1  million and a
market value of $105.6 million.

         During  February  2001 we  redeemed at par all $40 million of our 7.25%
convertible  subordinated debentures due October 2001. In March 2001 we redeemed
at par all  $162  million  of our  outstanding  7.50%  convertible  subordinated
debentures due October 2003. We funded these  redemptions using cash on hand and
proceeds from the preferred share offering  discussed  below. In connection with
these redemptions,  we recognized an extraordinary loss of $1.8 million from the
write-off of deferred financing fees.

         In February 2001 we completed a $200 million public  offering of 9 7/8%
series A cumulative  redeemable  preferred shares raising net proceeds of $193.3
million.  Approximately  half of the net proceeds were used to redeem all of our
outstanding  convertible  subordinated  debentures.  The remaining  proceeds are
available  to  repurchase  some of our common  shares and for  general  business
purposes,  including  the  repayment of  additional  debt.  On April 9, 2001, we
announced a distribution on our series A cumulative  redeemable preferred shares
of $0.5555  per share which will be  distributed  on or about May 15,  2001,  to
shareholders  of record as of May 1,  2001.  This  distribution  relates  to the
period from (but excluding) the original issue date through May 15, 2001,  which
is for less than one full quarter.

         Our Board of Trustees has authorized the repurchase of up to 14 million
common  shares.  During the three months ended March 31,  2001,  we  repurchased
983,700 common shares for $7.8 million,  including transaction costs. Subsequent
to March 31,  2001,  and through May 10, 2001,  we  repurchased  322,200  common
shares for $2.7 million, including transaction costs.

         At March 31, 2001, we had $85.8  million of cash and cash  equivalents,
zero  outstanding on our unsecured  revolving  credit  facility and $2.3 billion
available on our $3 billion  effective shelf  registration  statement.  Cash and
cash  equivalents  increased in 2001 primarily due to excess  proceeds  received
from a debt  financing  during  December 2000 and the preferred  share  offering
described  above.  We expect to use these excess  proceeds to repurchase some of
our common  shares or for general  business  purposes,  including  the  possible
repayment of additional debt and property acquisitions.

         In April 2001 we entered  into a new $425 million  unsecured  revolving
credit  facility  (the "New Credit  Facility").  The New Credit  Facility  bears
interest  at LIBOR plus a premium  and  matures in April  2005.  This New Credit
Facility replaces our $500 million unsecured revolving credit facility which was
scheduled  to mature in 2002.  The New Credit  Facility  includes  an  accordian
feature which allows it to be expanded, in certain circumstances,  by up to $200
million.  Our credit  facility is available for property  acquisitions,  working
capital and for general business purposes.

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

         There  can be no  assurances  that  debt or  equity  financing  will be
available to fund future  business  activities,  but we do expect that financing
will be available.  As of March 31, 2001, our debt as a percentage of total book
capitalization was approximately 39%.

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 March 31, 2001, our total outstanding
debt of $1.1 billion consisted of the following fixed rate notes:

               Amount                   Coupon                        Maturity
Unsecured senior notes:
             $160.0 million              6.875%                         2002
              150.0 million               6.75%                         2002
              100.0 million               6.70%                         2005
               90.0 million              7.875%                         2009
               30.0 million              8.875%                         2010
               20.0 million              8.625%                         2010
               65.0 million              8.375%                         2011
              143.0 million               8.50%                         2013
Secured notes:
               $3.5 million               9.12%                         2004
               10.9 million               8.40%                         2007
               17.4 million               7.02%                         2008
               11.3 million               8.00%                         2008
                9.9 million               7.66%                         2009
              259.5 million              6.814%                         2011
               44.0 million              6.794%                         2029

         No principal  repayments  are due on the  unsecured  senior notes until
maturity.  If all of the  unsecured  senior  notes and secured  notes were to be
refinanced at interest  rates which are one  percentage  point higher than shown
above,  our per annum  interest  cost  would  increase  by  approximately  $11.1
million. The secured notes are secured by 25 of our office properties located in
12  office  complexes  and  require  principal  and  interest  payments  through
maturity.

         The market prices,  if any, of each of our fixed rate obligations as of
March 31, 2001, are 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
balances  outstanding at March 31, 2001, and  discounted  cash flow analyses,  a
hypothetical  immediate  one  percentage  point  change in interest  rates would
change the fair value of our fixed rate debt obligations by approximately  $34.1
million.

         Each of our obligations for borrowed money has provisions that allow us
to make repayments  earlier than the stated maturity date. In some cases, we are
not allowed to make early repayment prior to a cutoff date and in other cases we
are allowed to make  prepayments  only at a premium to face value. In any event,
these  prepayment  rights may afford us the  opportunity to mitigate the risk of
refinancing  at maturity at higher rates by  refinancing at lower rates prior to
maturity.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk - continued

         In April 2001 we entered  into a new $425 million  unsecured  revolving
credit  facility  which will expire in April  2005.  This new  revolving  credit
facility will replace our $500 million unsecured revolving credit facility which
had zero outstanding at March 31, 2001. We borrow in U.S. dollars and borrowings
under  the new  facility  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 several  months,  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 of March 31, 2001, we had zero
outstanding under our revolving credit facility and we did not have any interest
rate cap or other hedge agreements to protect against future rate increases, but
we may enter such agreements in the future.  Also, we may incur  additional debt
at floating or fixed rates,  which would increase our exposure to market changes
in interest rates.

Part II  Other Information

Item 5.  Other Events

New Credit  Facility - As  previously  announced,  on April 30, 2001, we entered
into a new unsecured  senior  revolving credit facility with a group of banks in
the  initial  amount  of $425  million.  The new  credit  facility  includes  an
accordion  feature,  which allows us to seek  additional  lender  commitments to
expand the  facility  by up to $200  million to create a total  facility of $625
million.  The new credit  facility  matures on April 30, 2005 and  replaced  our
previous $500 million  unsecured senior  revolving  credit  facility,  which was
scheduled  to mature in April 2002.  Interest  under the new credit  facility is
generally  calculated  at LIBOR  plus  spreads  which  vary  based on our credit
ratings,  and we are also required to pay a facility fee on the aggregate lender
commitments.  The  proceeds of the new credit  facility  are  available  for our
general  business  purposes,  including  acquisitions.  The new credit  facility
documentation has several covenants,  including  covenants to maintain a minimum
consolidated net worth and which prohibit us and our subsidiaries from incurring
debt which would result in our total debt to exceed 55% of our total asset value
(each as determined under definitions  contained in the new credit facility).  A
copy of the new credit  facility is filed as an exhibit to this  Report.  If you
want more information  concerning the new credit  facility,  you should refer to
that exhibit.
