IMPORTANT FACTORS

         This Annual Report on Form 10-K contains  statements  which  constitute
forward  looking  statements  within the  meaning of the  Securities  Litigation
Reform Act of 1995. These  statements  appear in a number of places in this Form
10-K regarding our intent, belief or expectations with respect to the outcome of
current  agreements  and  negotiations  with certain of our tenants which are in
bankruptcy  proceedings,  our  ability  to obtain  requisite  approvals  for any

back from financially  troubled  tenants,  possible  expansion of our portfolio,
performance of our assets, our ability to make distributions, policies and plans
regarding investments, financings and other matters, the effect of the year 2000
issue,  our  ability  to  successfully  negotiate  with some of our  tenants  in
bankruptcy,  our tax status as a real estate  investment  trust,  our ability to

Item 1.  Business

         The Company.  Senior Housing  Properties Trust ("Senior Housing") is a
Maryland real estate  investment  trust  ("REIT") that invests in senior housing
income producing real estate,  including senior  apartments and assisted living,
congregate  care and nursing home  properties.  Senior  Housing was organized on
December 16, 1998 as a 100% owned  subsidiary of HRPT Properties Trust ("HRPT"),
a REIT which invests principally in office buildings.  On October 12, 1999, HRPT
distributed 13.2 million common shares of Senior Housing to HRPT shareholders to
create Senior  Housing as a separate  public REIT.  Senior  Housing's  principal
executive offices are located at 400 Centre Street, Newton, Massachusetts 02458,
and its telephone number is (617) 796-8350.

         As of December 31, 1999, we owned 81 properties for a total  investment
of $708.8  million and had mortgage  investments  in 12  properties  aggregating
$22.9 million,  net of loan loss reserve,  for total real estate  investments of
$731.7  million in 26 states.  The properties are described in greater detail in
"Item 2. Properties."

         We believe that the aging of the United States population will increase
the demand for existing senior  apartments,  congregate  communities,  assisting
living properties and nursing homes and encourage development of new properties.
Our basic  business plan is to profit from this  increasing  demand in two ways.
First,  we intend to purchase  additional  properties  and lease them at initial
rents that are greater than our costs of acquisition capital.  Second, we intend
to structure  leases that provide for periodic rental increases based in part on
gross  operating  revenue  increases at our  properties.  Our current  operating
environment,  though,  is  challenging.  The long  term care  industry  has been
financially  devastated by Medicare payment reductions,  increased  governmental
regulation,  rapid growth of the competing  assisting  living industry and tight
capital markets. The current difficulties being faced by the healthcare industry
have severely affected some of our tenants.

         Our business plan  contemplates  investment  in properties  which offer
four types of senior  housing  accommodations,  including some  properties  that
combine more than one type in a single building or campus.

         Senior Apartments.  Senior apartments are marketed to residents who are
generally capable of caring for themselves. Residence is generally restricted on
the basis of age.  Purpose built  properties  may have special  function  rooms,
concierge  services,  high levels of security and  centralized  call buttons for
emergency use.  Tenants at these  properties  who need  healthcare or assistance
with the activities of daily living are expected to contract  independently  for
those services with homemakers or home healthcare companies.

         Congregate  Communities.  Congregate  communities  also  provide a high
level of privacy to residents and require  residents to be capable of relatively
high degrees of independence.  Unlike a senior apartment property,  a congregate
community  usually  bundles  several  services  as  part  of a  regular  monthly
charge--for  example,  one or two meals per day in a central dining room, weekly
maid service or a social director.  Additional  services are generally available
from staff  employees on a  fee-for-service  charge  basis.  In some  congregate
communities,  separate parts of the property are dedicated to assisted living or
nursing services.

         Assisted Living  Properties.  Assisted living  properties are typically
comprised of one bedroom suites which include  private  bathrooms and efficiency
kitchens.  Services  provided  usually  include three meals per day in a central
dining  room,  daily  housekeeping,  laundry,  medical  reminders  and  24  hour
availability  of assistance with the activities of daily living such as dressing
and bathing.  Professional nursing and healthcare services are usually available
at the facility on call or at regularly  scheduled times.  Since the early 1990s
there  has  been  explosive  growth  in the  number  of small  public  companies
developing  purpose built assisted living  properties.  Many of those properties
have  recently  been  completed  and  are now  fully  occupied  and  appropriate
investments for us.

         Nursing Homes.  Nursing homes generally  provide  extensive nursing and
healthcare  services  similar to those available in hospitals,  without the high
costs  associated  with operating  theaters,  emergency  rooms or intensive care
units. A typical purpose built nursing home includes mostly two-bed rooms with a
separate  toilet in each room and shared  dining and  bathing  facilities.  Some
private  rooms are often  available  for those  residents  who can afford to pay
higher rates or for  patients  whose  medical  conditions  require  segregation.
Nursing homes are generally  staffed by licensed nursing  professionals 24 hours
per day.

         During the past few years nursing home owners and operators  have faced
two significant business challenges.  First, the rapid expansion of the assisted
living  industry  which  started in the early  1990s has  attracted  a number of
residents away from nursing homes. This was especially  significant  because the
residents who elected  assisted living  facilities had often previously been the
most profitable residents in the nursing  homes--residents who required a lesser
amount  of care  and who were  able to pay  higher  private  rates  rather  than
government rates.

         The second major  challenge  arose as a result of Medicare and Medicaid
cost containment laws beginning in 1994,  particularly 1997 federal  legislation
that required the Medicare  program to implement a prospective  payment  program
for various subacute services provided in skilled nursing homes.  Implementation

                                       2
<PAGE>
of this Medicare prospective payment program began on July 1, 1998. Prior to the
prospective  payment  program  Medicare paid nursing home  operators  based upon
audited  costs for  services  provided.  The  prospective  payment  system  sets
Medicare  rates based upon  government  estimated  costs of  treating  specified
medical conditions. Although it is possible that a nursing home may increase its
profit if it is able to provide  quality  services at below  average  costs,  we
believe that the effect of the new Medicare rate setting  methodology will be to
reduce the  profitability of Medicare  services in nursing homes. This belief is
based on similar Medicare changes that were implemented for hospitals during the
1980s.

         Tenants and Leases. Our financial  condition  depends,  in part, on the
financial  condition  of our  tenants.  About  46% of our  historical  rents are
received  from  Marriott  International,  Inc.  and  some  of  its  subsidiaries
("Marriott") and Brookdale Living Communities, Inc. and some of its subsidiaries
("Brookdale").  Our properties  leased to these  operators  predominantly  offer
independent  and  assisted  living  services;  and almost all of the revenues of
these  properties  are paid by residents from private  resources.  As previously
announced, our other large tenants, Integrated Health Services, Inc. ("IHS") and
Mariner  Post-Acute  Network,  Inc.  ("Mariner"),  which  on  a  combined  basis
represent about 48% of our historical rents, filed for bankruptcy in early 2000.
More  information  concerning  those tenants is set forth below under  "Business
Developments--Tenant  Financial Condition." Properties leased to IHS and Mariner
are predominantly nursing homes.

         Our leases are so called  "triple net" leases which require the tenants
to  maintain  our  properties  during the lease  terms and to  indemnify  us for
liability which may arise by reason of our ownership of the properties.

         We own 14 congregate care  communities  and assisted living  properties
located in seven  states  with 3,950  units that are leased to  subsidiaries  of
Marriott.  Marriott  is  a  NYSE  listed  company  whose  major  businesses  are
developing,  operating and managing hotels,  senior housing  properties and time
share resorts.  The annual rent under this lease is $30.9 million,  which is 34%
of our  historical  total annual rent, and the lease provides for rent increases
equal to 4.5% of increases  in gross  revenues of the  properties.  Marriott has
guaranteed  all of these lease  obligations.  Our historic  investment  in these
properties is $325.5 million. The current lease expiration is 2013, and Marriott
has four all-or-none renewal options for five years each.

         We own four congregate care communities located in four states with 829
units that are leased to a subsidiary of Brookdale. Brookdale is a Nasdaq listed
company whose principal business is operating senior housing and congregate care
communities.  The annual rent under this lease is $11.2 million, which is 12% of
our  historical  total annual rent,  and the lease  provides for rent  increases
equal to 10% of increases in gross revenues of the properties  starting in 1999.
Brookdale has guaranteed all of these lease obligations. Our historic investment
in these properties is $101.9 million. The current lease expiration is 2019, and
Brookdale has two all-or-none renewal options for twenty-five years each.

         We own one nursing  home with 150 units that is leased to a  subsidiary
of Genesis Health Ventures,  Inc. ("Genesis").  Genesis is a NYSE listed company
whose major businesses are operating nursing homes,

                                       3
<PAGE>

congregate care  communities and assisting  living  properties.  The annual rent
under this lease is $1.4 million,  which is two percent of our historical  total
annual rent, and the lease  provides for annual rent  increases of $13,000.  Our
historic  investment  in this  property  is $13.0  million.  The  current  lease
expiration  is 2005,  and Genesis has two  all-or-none  renewal  options for ten
years each and one for five years.

         In addition to the tenants  described  above,  we currently lease three
nursing homes located in three states with 423 units to three  separate  private
companies. These leases require total annual rent of $1.3 million.

         We  currently  own 27 nursing  homes and three senior  apartments  with
3,205 units  located in nine states that are leased to  subsidiaries  of IHS. In
addition,  we have mortgage  investments  secured by 12 nursing homes with 1,070
units located in three states that are operated by IHS.  IHS's major  businesses
are operating  nursing homes and providing home  healthcare  services.  These 42
properties  are divided  into two pools,  and the  obligations  under leases and
mortgages  within each pool are subject to cross  default and  collateralization
covenants  with all other  properties  in the same pool.  The annual  rent under
these  leases of $22.8  million  and the  interest  of $4.1  totaled  30% of our
historical  total  annual  rent.  IHS has  guaranteed  all of these  leases  and
mortgage  obligations.  IHS and  its  subsidiaries  which  are  our  tenants  or
mortgagors    are   subject   to   bankruptcy    proceedings.    See   "Business
Developments--Tenant  Financial  Condition."  The current lease  expirations are
2006 in the case of one pool and  2010 in the case of the  other  (in each  case
with renewal options), subject to the effect of the bankruptcy proceedings.  Our
investment in these  properties,  after an impairment  loss  write-down and loan
loss reserve, is $185.2 million.

         We currently own 24 nursing homes and two congregate  care  communities
with 3,482  units  located  in six states  leased to  subsidiaries  of  Mariner.
Mariner's  principal  business is operating  nursing  homes.  The $16.7  million
annual rent under this lease represents about 18% of our historical total annual
rent.  Mariner has  guaranteed all of the lease  obligations.  Our investment in
these properties  after an impairment loss write-down is $80.7 million.  Mariner
and  its   subsidiaries   which  are  our  tenants  are  subject  to  bankruptcy
proceedings.  See  "Business   Developments--Tenant  Financial  Condition."  The
current lease term with Mariner expires in 2013 (with renewal options),  subject
to the effect of the  bankruptcy  proceedings.  We have  reached an agreement in
principle with Mariner  involving,  among other things,  the  termination of the
lease of the properties,  our assumption of operating responsibilities for 17 of
the properties  and our conveyance of title to the remaining five  properties to
Mariner.  The  remaining  four  nursing  homes are now  subleased to two private
companies  and we expect  to  negotiate  with  these  two  subtenants  for their
continued  operations of those  properties.  Our  agreement is  contingent  upon
approval of Mariner's  creditors committee and the bankruptcy court and required
regulatory approvals.

                                       4
<PAGE>

         Other terms of our leases have included and may in the future generally
include the following:

         Cross Default.  When we lease more than one property to a single tenant
or a group of affiliated tenants all those leases are cross defaulted.

         All or None Renewal Options.  When we lease more than one property to a
single tenant or a group of affiliated  tenants,  lease renewal options may only
be exercised on an all or none basis.

         Maintenance and Alterations.  Our tenants are required to maintain,  at
their  expense,  the  leased  properties  in good  order and  repair,  including
structural  and  nonstructural  maintenance.  Except  in the case of  properties
leased to Marriott,  capital  alterations  and additions to any leased  property
which  exceed a  threshold  amount of  aggregate  cost may only be made with our
prior consent.  Any  alterations  or  improvements  made to any leased  property
during the terms of the leases become our property, subject to our obligation to
pay to the tenants  unamortized  costs at lease  termination.  At the end of the
leases,  our tenants are  required  to  surrender  their  leased  properties  in
substantially  the same  condition as existed on the  commencement  dates of the
leases,  subject to any permitted  alterations  and subject to ordinary wear and
tear.

         Assignment.  Our consent is generally  required for any  assignment  or
sublease of our  properties.  In the event of a subletting,  the initial  tenant
remains liable under the lease and all  guarantees and other security  remain in
place.

         Environmental  Matters. Our tenants are required,  at their expense, to
remove and  dispose of any  hazardous  substance  at the  leased  properties  in
compliance with all applicable environmental laws and regulations and to pay any
costs we incur  in  connection  with  removal  and  disposal.  Each  tenant  has
indemnified us for any claims  asserted as a result of the presence of hazardous
substances  at any  property  and from a violation  or alleged  violation of any
applicable environmental law or regulation.

         Indemnification  and Insurance.  Each tenant has agreed to indemnify us
from all claims arising from our ownership or their use of our properties.  Each
tenant is required to maintain insurance on our properties covering:

     o    comprehensive  general  liability  for  damage to  property  or bodily
          injury arising out of the ownership,  use, occupancy or maintenance of
          the properties;

     o    commercial  property "all risk" liability for damage to  improvements,
          merchandise,  trade  fixtures,  furnishings,  equipment  and  personal
          property;

     o    workers' compensation liability;

     o    business interruption loss;

     o    in some cases, medical malpractice; and

     o    other losses customarily insured by businesses similar to the business
          conducted at our properties.

The  leases  require  that we be  named as an  additional  insured  under  these
policies.

         Damage, Destruction or Condemnation. In the event any of our properties
is damaged by fire,  or other  casualty or is taken for a public use, we receive
all  insurance  or taking  proceeds  and our  tenants  are  required  to pay any
difference between the amount of proceeds and the historical investment by us or
HRPT  in the  affected  property.  In  the  event  of  material  destruction  or
condemnation,  some tenants  have a right to purchase the affected  property for
amounts at least equal to our or HRPT's historical investment in the property.

                                       5
<PAGE>

         Events of Default Events of default include:

     o    the failure of the tenant to pay rent when due;

     o    the  failure  of  the  tenant  to  perform  key  terms,  covenants  or
          conditions  of its lease and the  continuance  thereof for a specified
          period after written notice;

     o    the occurrence of events of insolvency with respect to the tenant;

     o    the failure of the tenant to maintain required insurance coverages; or

     o    the  revocation  of any material  license  necessary  for the tenant's
          operation of our property.

         Remedies.  Upon the occurrence of any event of default, we may (subject
to applicable law):

     o    terminate the affected lease and accelerate the rent;

     o    terminate  the  tenant's  rights to the affected  property,  relet the
          property and recover from the tenant the difference between the amount
          of rent which would have been due under the  applicable  lease and the
          rent received under the reletting; and

     o    make any payment or perform any act  required to be  performed  by the
          tenant under its lease.

The defaulting tenant is obligated to reimburse us for all payments made and all
costs and expenses  incurred in  connection  with any exercise of the  foregoing
remedies.

         Ground  Lease  Terms.  The land  underlying  two of our  properties  is
leased.  Our leases  require  our  tenants to pay and  perform  all  obligations
arising under these ground  leases.  These ground  leases  terminate on 2086 and
2079. The annual rents payable under the ground leases in 1999 totaled $138,100.
If our tenants fail to pay the  applicable  ground rent, we may have to do so in
order to protect our investment in these properties.

         The following discussion sets forth our policies regarding investments,
dispositions,  financings  and other  activities.  The board of trustees has set
these policies and although there is no current intention to do so, the board of
trustees  may  amend or  revise  these  policies  at any time  without a vote of
shareholders.

Investment Policies

         Acquisitions.  Our investment  goals are to acquire  additional  senior
apartments,  congregate  communities,  assisted  living  properties  and nursing
homes, primarily for income and secondarily for their appreciation potential. In
making future acquisitions, we will consider a range of factors including:

     o    the acquisition price of the proposed property;

     o    the estimated replacement cost of the proposed property;

     o    proposed lease terms;

     o    the  financial  strength  and  operating  reputation  of the  proposed
          tenant;

     o    historical and projected cash flows of the property to be acquired;

     o    the  location  and  competitive  market  environment  of the  proposed
          property;

                                       6
<PAGE>

     o    the physical  condition of the proposed property and its potential for
          redevelopment or expansion; and

     o    the price segment and payment  sources in which the proposed  property
          is operated.

         We intend to acquire properties which will enhance the diversity of our
portfolio in respect to tenants,  types of services  provided and locations.  We
have no policies which specifically limit the percentage of our assets which may
be  invested  in any  individual  property,  in any  one  type of  property,  in
properties  leased to any one tenant or in  properties  leased to an  affiliated
group of tenants.

         Other  Investment  in Real  Estate.  We emphasize  direct  wholly owned
investments in fee interests.  However,  circumstances may arise in which we may
invest in leaseholds, joint ventures, mortgages and other real estate interests.
We may invest in real estate joint  ventures if we conclude  that by doing so we
may benefit from the  participation  of  co-venturers or that our opportunity to
participate  in the  investment  is  contingent  on the use of a  joint  venture
structure.  We may  invest  in  participating,  convertible  or  other  types of
mortgages  if we conclude  that by doing so we may benefit from the cash flow or
appreciation in the value of a property which is not available for purchase.

Disposition Policies

         From time to time we may consider  the sale of one or more  properties.
Future disposition decisions,  if any, will be made based on a number of factors
including the following:

     o    the proposed sale price;

     o    the strategic fit of the property with the rest of our portfolio;

     o    potential  opportunities  to  increase  revenues by  reinvesting  sale
          proceeds;

     o    the  potential  for,  or  the  existence  of,  any   environmental  or
          regulatory problems affecting a particular property;

     o    our alternative capital needs; and

     o    the  maintenance  of our  qualification  as a REIT under the  Internal
          Revenue Code.

         We contemplate certain dispositions in connection with our negotiations
with  two  tenants   which  are  in   bankruptcy   proceedings.   See  "Business
Developments--Tenant Financial Condition."

Financing Policies

         We have a $350 million  bank credit  facility.  The  facility  requires
payment of interest  only at LIBOR plus a premium prior to maturity on September
15,  2002.  Outstanding  borrowings  under the  facility  were $200  million  at
December 31, 1999. This bank credit facility is secured by first mortgages upon,
and a collateral  assignment  of leases from,  18  properties.  This bank credit
facility has several  covenants  typically  found in revolving  loan  facilities
including covenants to maintain a minimum net worth and minimum collateral value
and which prohibit us from incurring debt in excess of 60% of its total capital.

         We use this bank credit facility to fund  acquisitions  and for working
capital.  Periodically,  we expect to repay  amounts drawn under the bank credit
facility   with   proceeds  of  equity  and  long  term  debt   offerings.   Our
organizational  documents do not limit the amount of  indebtedness we may incur.
At present we expect to maintain a capital  structure in which our debt will not
exceed 60% of our total capital.  We will consider future equity offerings when,
in our judgment,  doing so will improve our capital structure without materially
adversely

                                       7
<PAGE>

affecting the market value of its shares.  Unless we achieve an investment grade
rating at some  future  date,  we  expect  that the least  costly  debt  capital
available  to us will be secured debt and that most of our debt will be secured.
In the  future,  we may modify our current  financing  policies in light of then
current  economic  conditions,  relative  costs  of  debt  and  equity  capital,
acquisition  opportunities and other factors;  and our intended ratio of debt to
total capital may change.

Policies with Respect to Other Activities

         We operate in a manner that will not subject us to regulation under the
Investment  Company Act of 1940.  Except for the possible  acquisition  of other
REITs which are engaged in similar  businesses,  we do not  currently  intend to
invest in the  securities  of other  companies  for the  purpose  of  exercising
control,  to underwrite  securities of other  companies or to trade  actively in
loans or other investments.

         We may make investments other than as previously described, although we
do not currently  intend to do so. We have  authority to repurchase or otherwise
reacquire  our shares or other  securities we issue and may do so in the future.
In the future, we may issue shares or other securities in exchange for property.
Also, although we have no current intention to do so, we may make loans to third
parties,  including to our trustees and officers and to joint  ventures in which
we participate.

Business Developments

Spin-Off

         In September 1999, our registration statement on Form S-11 was declared
effective by the Securities and Exchange Commission. As a result, on October 12,
1999, a majority  ownership of our shares were distributed to HRPT  shareholders
through a special  distribution (the "Spin-Off").  Subsequently,  both companies
trade separately on the New York Stock Exchange.

Tenant Financial Condition

         Three of our tenants,  The Frontier Group, Inc.  ("Frontier"),  Mariner
and IHS, have filed for protection under bankruptcy laws. Frontier filed in July
1999,  Mariner filed in January 2000 and IHS filed in February 2000.  Bankruptcy
laws may allow  our  tenants  relief or  discharge  them  from  their  financial
obligations  to us. For 1999,  rental  income and mortgage  interest  related to
Frontier,  Mariner and IHS was $2.2 million,  $15.4  million and $26.6  million,
respectively.   At  December  31,  1999,  our  historical  investments,   before
impairment loss  recognition  and net of accumulated  depreciation in properties
operated by these three tenants,  were $10.0  million,  $68.3 million and $136.9
million,  respectively. We also had mortgage investments,  before loss reserves,
related to properties operated by IHS of $36.6 million at December 31, 1999.

         We have concluded that  impairment  indicators are present with respect
to properties operated by these tenants and have prepared undiscounted cash flow
projections for each of the properties.  For purposes of these  projections,  we
have assumed that rents on some  properties may be modified and that some of the
leases may be terminated after which we will operate the properties for a period
of time and, ultimately, sell them. In addition, a third party not in bankruptcy
is responsible for the lease  obligations of some of the properties  operated by
IHS. We have assumed that the guarantor will honor these lease obligations.  The
undiscounted cash flow projections  reflect the expected rents to be earned over
the lease term and the expected cash flows earned from  operating the properties
for a  period  of time  plus  the  proceeds  from  assumed  future  sales of the
properties.  Cash flows during the period in which we may operate the properties
are estimated  based on the historical  performance of each property,  excluding
rent paid to us.  Projected  sale prices are based on an estimated per bed value
consistent  with industry  practice and reflect  prices that we have observed in
recent transactions.  Based on these undiscounted cash flow projections, we have
concluded that some of our real estate and mortgage investments were impaired as
of December 31, 1999.  Based on our estimated  fair values net of selling costs,
we have  written  down the  carrying  value of these  real  estate  investments,
including investments leased to an affiliate,

                                       8
<PAGE>

Advisors  Healthcare Group,  Inc., and operated by IHS, as of December 31, 1999,
by recording an  impairment  loss  write-down in the  accompanying  consolidated
statement of income of $15.5 million. In addition,  we have recorded a loan loss
reserve  of $14.5  million  related to the  mortgage  investment  we  considered
impaired.  At December 31, 1999 after impairment losses,  loan loss reserves and
net of accumulated  depreciation,  the net book value of the properties operated
by  Frontier,  IHS and  Mariner  were $10.0  million,  $147.5  million and $65.2
million,  respectively.  It is reasonably possible that estimates of future cash
flows could be reduced significantly  depending on the outcome of the bankruptcy
proceedings  or if the  non-bankrupt  third  party  should  fail  to  honor  its
obligations.  As a  result,  additional  losses  could be  recognized  in future
periods and these amounts could be material.

         In February  2000,  we sold all of the  properties  that were leased to
Frontier for $13.0 million.  We are continuing  pursuing claims against Frontier
and other parties for breach of its leases and for rental arrearages. The amount
of net  gain,  if any,  which  may be  realized  from the  sale of the  Frontier
properties  will depend upon the outcome of these claims.  The amount of gain or
loss to be  realized  as a result  of this  transaction  is not  expected  to be
material.  Because these  properties  have been sold, we will no longer  receive
rental income from these properties.

         In March 2000,  we reached an agreement  in  principle  with Mariner as
follows:

     o    Mariner's  lease  obligations  for all 26 properties  which we own and
          lease to Mariner will be terminated.

     o    Approximately  $24.0 million of cash and  securities  which we hold to
          secure Mariner's obligations will be retained by us.

     o    We  will  assume  operating   responsibilities  for  17  of  these  26
          properties.  Title to five of these  properties will be transferred to
          Mariner which will continue the operations. The remaining four nursing
          homes are now  subleased  to two  private  companies  and we expect to
          negotiate with these two subtenants for their continued  operations of
          those properties.

         Our  agreement  with Mariner is  contingent  upon approval by Mariner's
creditors  committee and the Delaware  Bankruptcy  Court before which  Mariner's
bankruptcy  is pending and required  regulatory  approvals  from various  states
where  affected  nursing  homes are  located.  If this  agreement is approved we
expect that we may realize gains and that our future earnings and cash flows may
be less than the rent previously  earned from the Mariner leases,  at least on a
short term basis. This agreement is contingent upon third party approvals beyond
our  control.  If and when  this  agreement  is  implemented  it may  result  in
additional material gains or losses.

         We are  currently in  negotiations  with IHS. The current  negotiations
include, but are not limited to, the possibilities that we will sell some of the
properties,  that lease or mortgage  terms may be changed,  that new tenants may
begin  operations of properties,  that  properties may be operated by us for our
own account or that  mortgage  obligations  due to us may be released  for other
compensation.   We  may  recognize   additional   gains  or  losses  when  these
negotiations are completed and the additional gains or losses may be material.

Investments

         There were no new investments made during 1999.

the Spin-Off,  we entered into a new  investment  advisory  agreement  with REIT
Management,  pursuant to which REIT Management provides  investment,  management
and  administrative  services  to us. The  agreement  has been  renewed  through
December 31, 2000. REIT  Management also acts as the investment  manager to HRPT
and has other business interests. The Directors of REIT Management are Gerard M.
Martin,  Barry M. Portnoy and David J. Hegarty.  The officers of REIT Management
are David J. Hegarty,  President and Secretary,  John G. Murray,  Executive Vice
President,  John Popeo,  Treasurer,  and Ajay Saini,  John A.  Mannix,  David M.
Lepore,  Thomas M. O'Brien and  Jennifer B. Clark,  Vice  Presidents.  Gerard M.
Martin and Barry M. Portnoy are our managing trustees,  and David J. Hegarty and
Ajay Saini are our officers.

Employees

         As of March 27,  2000,  we had no  employees.  REIT  Management,  which
administers our day-to-day operations, had about 200 full-time employees.

Regulation and Reimbursement

         The  tenants  and  borrowers  who  operate  our  properties,  including
long-term care facilities,  congregate communities,  assisted living centers and
senior  apartments,  must  comply with  federal,  state and local  statutes  and
regulations in order to operate the properties. The health care industry depends
significantly  upon federal and  federal/state  programs for revenues  and, as a
result,  is vulnerable  to the budgetary  policies of both the federal and state
governments.

Government Regulations and Rate Setting

         Senior  Apartments.  Generally,  government  programs  do not  pay  for
housing  in  senior  apartments.  Rents  are paid  from the  residents'  private
resources.  Accordingly, the government regulations that apply to these types of
properties are generally limited to zoning,  building and fire codes,  Americans
with  Disabilities  Act  requirements  and other life  safety  type  regulations
applicable to residential real estate.  Government rent subsidies and government
assisted  development  financing for low income senior housing are exceptions to
these general  statements.  The development  and operation of subsidized  senior
housing properties are subject to numerous governmental regulations. While it is
possible  that we may  purchase  and  lease  some  subsidized  senior  apartment
properties,  we do not expect these investments to be a major part of our future
business, and today we own no properties where rent subsidies are applicable.

         Congregate   Communities.   We  understand  that  generally  government
benefits are not available to congregate communities and the resident charges in
these properties are paid from private  resources.  However, a number of Federal
Supplemental  Security Income program  benefits pay housing costs for elderly or
disabled residents to live in these types of residential facilities.  The Social
Security Act requires  states to certify  that they will  establish  and enforce
standards  for any category of group living  arrangement  in which a significant
number of supplemental security income residents reside or are likely to reside.
Categories of living  arrangements which may be subject to these state standards
include congregate facilities and assisted living properties. Because congregate
communities  usually offer common dining facilities,  in many locations they are
required  to  obtain  licenses  applicable  to food  service  establishments  in
addition  to  complying  with  land use and life  safety  requirements.  In many
states, congregate communities are licensed by state health departments,  social
service  agencies,  or offices on aging with jurisdiction over group residential
facilities for seniors. To the extent that congregate communities maintain units
in which  assisted  living or nursing  services  are  provided,  these units are
subject to applicable state regulations.  In some states,  insurance or consumer
protection  agencies  regulate  congregate  communities  in which  residents pay
entrance fees or prepay other costs.

         Assisted  Living.  According to the  National  Academy for State Health
Policy,  39 states  provide  Medicaid  payments for  residents in some  assisted
living   properties   under   waivers   granted  by  the  Health  Care   Finance
Administration  of the U.S.  Department  of Health and Human  Services  or under
Medicaid state plans and three other states are planning to do so. Because rates
paid to assisted living property  operators are lower

                                       10
<PAGE>
than rates paid to nursing home operators some states use this waiver program as
a means of lowering  the cost of  services  for  residents  who may not need the
higher  intensity  of medical  care  provided  in  nursing  homes.  States  that
administer  Medicaid programs for assisted living facilities are responsible for
monitoring  the  services  at  and  physical  conditions  of  the  participating
properties.  Different  states apply different  standards in these matters,  but
generally we believe  these  monitoring  processes  are similar to the concerned
states' inspection processes for nursing homes.

         Because  of the large  number  of states  using  Medicaid  to  purchase
services at assisted living properties,  it is not surprising that a majority of
states  have  adopted   licensing   standards   applicable  to  assisted  living
facilities. The National Academy for State Health Policy reported in November of
1999  that 29  states  had  implemented  licensing  standards  specifically  for
assisted living, rules were being drafted in another three states and another 11
states were  currently  studying the regulation of assisted  living  facilities.
State regulatory models vary; there is no national  consensus on a definition of
assisted living,  and no uniform  approach by the states to regulating  assisted
living  facilities.  Some state  licensing  standards  apply to assisted  living
facilities whether or not they accept Medicaid funding.  Moreover,  a 1998 study
by the  National  Academy for State  Health  Policy  found that  several  states
require  certificates of need from state health planning  authorities before new
assisted  living  properties  may be  developed,  and three  states have adopted
moratoria on the  development of new assisted  living  facilities.  Based on our
analysis of current  economic and  regulatory  trends,  we believe that assisted
living properties that become dependent upon Medicaid payments for a majority of
their revenues will decline in value because Medicaid rates will fail to keep up
with increasing costs. For the same reason, we also believe that assisted living
properties  located in states that adopt  certificate  of need  requirements  or
otherwise  restrict the  development  of new  assisted  living  properties  will
increase in value because these  limitations  upon  development will help ensure
higher occupancy and higher  non-governmental rates.  Accordingly,  we intend to
focus  new  investments  in  assisted  living  properties  that  are not  overly
dependent  upon  governmental  revenues  and that are in areas  where  there are
barriers to competition created by certificate of need laws or otherwise.

         Two federal  government  studies  were  recently  completed  to provide
background information and make recommendations regarding the regulation of, and
the  possibility  of increased  governmental  funding  for, the assisted  living
industry.  In April 1999, the General  Accounting  Office issued a report to the
Senate  Special  Committee on Aging and the Committee  held hearings on consumer
protection  and quality of care issues in assisted  living  facilities.  The GAO
studied  assisted  living  facilities  in four  states  and found a  variety  of
residential settings serving a wide range of resident health and care needs. The
GAO found  that  providers  often give  consumers  insufficient  information  to
determine  whether a  particular  facility  can meet their  needs and that state
licensing and oversight  approaches vary widely. The GAO anticipates that as the
states  increase  the  use of  Medicaid  to pay  for  assisted  living,  federal
financing will likewise grow, and these trends will focus more public  attention
on the place of assisted  living in the  continuum  of  long-term  care and upon
state standards and compliance  approaches.  The second study, a national survey
of assisted living facilities,  was funded by the Department of Health and Human
Services'  Assistant  Secretary for Planning and  Evaluation  and is expected to
result in  additional  reports which will touch upon all aspects of the assisted
living  industry  including  quality of care and  financing.  The 1998  National
Academy for State Health Policy study  referenced above and an April 1999 report
on the national  survey of assisted  living  facilities  are part of this second
study.  We cannot  predict  whether  these  studies will result in  governmental
policy changes or new  legislation,  or what impact any changes may have.  Based
upon our analysis of current economic and regulatory  trends,  we do not believe
that the federal government is likely to have a material impact upon the current
regulatory  environment in which the assisted living industry operates unless it
also undertakes expanded funding obligations; and we do not believe a materially
increased financial  commitment from the federal government is presently likely.
However,  we do anticipate that assisted living  facilities will increasingly be
licensed  and  regulated  by the  various  states,  and that with the absence of
federal standards, the states' policies will continue to vary widely.

         Nursing Homes. About 67% of all nursing home revenues in 1997 came from
government Medicare and Medicaid programs. Nursing homes are also among the most
highly regulated  businesses in the country.  The federal and state  governments
regularly  monitor the quality of care  provided at nursing  homes and regularly
inspect the  physical  condition  of nursing  home  properties.  These  periodic
inspections   and   occasional   changes  in

                                       11
<PAGE>
life safety and  physical  plant  requirements  sometimes  require  nursing home
owners  to  spend  money  for  capital  improvements.   These  mandated  capital
improvements  have in the past usually  resulted in Medicare  and Medicaid  rate
adjustments,  albeit on the basis of amortization of expenditures  over extended
useful lives of the improvements.  However,  under the new Medicare  prospective
payment  system,  which began being phased in over three years starting in 1998,
capital  costs  are  part of the  prospective  rate  and  will  not be  facility
specific.  Other recent legislative and regulatory actions with respect to state
Medicaid  rates and the  Medicare  prospective  payment  system are limiting the
reimbursement levels for some nursing home and other eldercare services.  At the
same time federal  enforcement  and  oversight of nursing  homes is  increasing,
thereby making  licensing and  certification  of these facilities more rigorous.
These actions have adversely affected the revenues and increased the expenses of
many nursing home operators, including several of our tenants.

         The federal  Health Care Financing  Administration,  HCFA, has begun to
implement an  initiative  to increase  the  effectiveness  of  Medicare/Medicaid
nursing facility survey and enforcement  activities.  HCFA's initiative  follows
its July  1998  report  to  Congress  on the  effectiveness  of the  survey  and
enforcement  system,  several  March 1999 reports by HCFA's  Office of Inspector
General  concerning  quality  of care in  nursing  homes,  a July  1998  General
Accounting  Office  investigation  which found  inadequate care in a significant
proportion  of  California  nursing  homes,  and a March 1999 GAO  report  which
recommended that HCFA and the states strengthen their compliance and enforcement
practices to better ensure that nursing homes provide adequate care. In 1998 and
1999, the Senate Special Committee on Aging held hearings on these issues.  HCFA
is taking steps to focus survey and  enforcement  efforts at nursing  homes with
repeat  violations  of  Medicare/Medicaid  standards,  including  chain-operated
facilities with patterns of noncompliance. HCFA also is requiring state agencies
to use  enforcement  sanctions and remedies more promptly and  effectively  when
substandard care is identified. HCFA is increasing its oversight of state survey
agencies.  In addition HCFA has adopted new  regulations  expanding  federal and
state authority to impose civil money  penalties in instances of  noncompliance.
Medicare/Medicaid  survey  results for each nursing home are being posted on the
internet.  Federal  efforts to target  fraud and abuse by Medicare  and Medicaid
providers have also increased. An adverse determination  concerning any tenant's
license or eligibility for Medicare or Medicaid  reimbursement or its compliance
with applicable  federal or state  regulation may adversely affect such operator
and its  affiliates  and may  restrict  its  ability  to pay rent  and  mortgage
interest.

         Most  states  also  limit the  number  of  nursing  homes by  requiring
developers to obtain  certificates  of need before new  facilities may be built.
Even  in  those  states  such as  California  and  Texas  that  have  eliminated
certificate  of need laws,  the state health  authorities  usually have retained
other means of limiting  new nursing home  development.  Examples of these other
means are the use of moratoria, licensing laws or limitations upon participation
in the state Medicaid program.  We believe that these  governmental  limitations
generally make nursing home  properties  more valuable by extending their useful
lives and limiting competition.

         A number of  legislative  proposals  that would affect major reforms of
the health care system have been  introduced  in  Congress,  such as  additional
Medicare and Medicaid reforms and cost containment  measures.  We cannot predict
whether any of these legislative  proposals will be adopted or, if adopted, what
effect,  if  any,  these  proposals  would  have  on our  business,  lessees  or
mortgagors.

Competition.

         We compete with other real estate  investment  trusts  which  regularly
seek attractive investment  opportunities in senior housing facilities.  We also
compete with banks, non-bank finance companies,  leasing companies and insurance
companies  which invest in this type of real estate.  Some of these  competitors
have resources that are greater than ours and have lower costs of capital.

                        FEDERAL INCOME TAX CONSIDERATIONS

         The following  summary of federal income tax and ERISA  consequences is
based on  existing  law,  and is  limited  to  investors  who own our  shares as
investment  assets  rather than as inventory  or as property  used in a trade or
business.  The summary does not discuss the  particular  tax  consequences  that
might be relevant  to you if you are subject to special  rules under the federal
income tax law, for example if you are:

     o    a bank, life insurance company, regulated investment company, or other
          financial institution,

     o    a broker or dealer in securities or foreign currency,

     o    a person who has a functional currency other than the U.S. dollar,

     o    a person who  acquires our shares in  connection  with  employment  or
          other performance of services,

     o    a person subject to alternative minimum tax,

     o    a  person  who  owns  our  shares  as  part  of  a  straddle,  hedging
          transaction, constructive sale transaction, or conversion transaction,
          or

     o    except  as  specifically   described  in  the  following   summary,  a
          tax-exempt entity or a foreign person.

The  sections of the Internal  Revenue  Code that govern the federal  income tax
qualification  and treatment of a REIT and its  shareholders  are complex.  This
presentation  is a summary  of  applicable  Internal  Revenue  Code  provisions,
related rules and regulations and administrative  and judicial  interpretations,
all of which are subject to change,  possibly with  retroactive  effect.  Future
legislative,  judicial, or administrative  actions or decisions could affect the
accuracy of statements  made in this  summary.  We have not sought a ruling from
the IRS with  respect to any matter  described  in this  summary,  and we cannot
assure you that the IRS or a court will agree with the  statements  made in this
summary.  In addition,  the following  summary is not exhaustive of all possible
tax  consequences,  and does not discuss  any estate,  gift,  state,  local,  or
foreign tax consequences. For all these reasons, we urge you and any prospective
acquiror of our shares to consult  with a tax advisor  about the federal  income
tax and other tax consequences of the acquisition,  ownership and disposition of
our shares.

         Federal income tax  consequences may differ depending on whether or not
you are a "U.S.  shareholder." For purposes of this summary, a U.S.  shareholder
for federal income tax purposes is:

     o    a  citizen  or  resident  of the  United  States,  including  an alien
          individual who is a lawful permanent  resident of the United States or
          meets the substantial presence residency test under the federal income
          tax laws,

     o    a corporation, partnership or other entity treated as a corporation or
          partnership  for  federal  income  tax  purposes,  that is  created or
          organized in or under the laws of the United States, any state thereof
          or the District of  Columbia,  unless  otherwise  provided by Treasury
          regulations,

     o    an estate the income of which is  subject to federal  income  taxation
          regardless of its source, or

     o    a trust  if a court  within  the  United  States  is able to  exercise
          primary  supervision over the  administration  of the trust and one or
          more  United  States   persons  have  the  authority  to  control  all
          substantial decisions of the trust, or electing trusts in existence on
          August 20, 1996 to the extent provided in Treasury regulations,

whose  status as a U.S.  shareholder  is not  overridden  by an  applicable  tax
treaty. Conversely, a "non-U.S. shareholder" is a beneficial owner of our shares
who is not a U.S. shareholder.

Taxation as a REIT

         We will elect to be taxed as a REIT under  Sections  856 through 860 of
the  Internal  Revenue Code  commencing  with our 1999  taxable  year.  Our 1999
taxable year began when we ceased to be wholly-owned by HRPT in October 1999 and
ended on December 31, 1999. Our REIT election,  assuming  continuing  compliance
with the federal income tax qualification  tests summarized below,  continues in
effect for  subsequent  taxable  years.  Although no assurance can be given,  we
believe that we are organized,  have operated, and will continue to operate in a
manner that qualifies us to be taxed under the Internal Revenue Code as a REIT.

         As a REIT,  we generally  will not be subject to federal  income tax on
our net income  distributed as dividends to our  shareholders.  Distributions to
our  shareholders  generally  will be includable in their income as dividends to
the extent of our current or  accumulated  earnings  and  profits.  A portion of
these dividends may be treated as capital gain dividends, as explained below. No
portion of any dividends will be eligible for the dividends  received  deduction
for corporate  shareholders.  Distributions  in excess of current or accumulated
earnings and profits  generally  will be treated for federal income tax purposes
as a return of capital to the extent of a recipient  shareholder's  basis in our
shares,  and will reduce this basis.  Our current or  accumulated  earnings  and
profits will generally be allocated  first to  distributions  on our outstanding
preferred shares, if any, and thereafter to distributions on our common shares.

         Our  counsel,  Sullivan & Worcester  LLP,  has opined that we have been
organized and have  qualified as a REIT under the Internal  Revenue Code for our
1999 taxable year, and that our current  investments  and plan of operation will
enable us to meet the  requirements  for  qualification  and  taxation as a REIT
under the Internal Revenue Code. Our actual qualification and taxation as a REIT
will  depend  upon our  ability to meet the  various  REIT  qualification  tests
imposed under the Internal Revenue Code and summarized  below.  While we believe
that we will  operate  in a manner to satisfy  the  various  REIT  qualification
tests,  our counsel has not reviewed and will not review  compliance  with these
tests on a  continuing  basis.  If we fail to qualify as a REIT in any year,  we
will be subject to federal income taxation as if we were a domestic corporation,
and our shareholders will be taxed like  shareholders of ordinary  corporations.
In this  event,  we could be subject to  significant  tax  liabilities,  and the
amount of cash available for  distribution to our shareholders may be reduced or
eliminated.

         If we qualify for  taxation as a REIT and meet the annual  distribution
tests  described  below,  we generally will not be subject to federal  corporate
income taxes on the amount distributed.  However, even if we qualify for federal
income  taxation as a REIT,  we may be subject to federal  tax in the  following
circumstances:

     o    We will be taxed at regular corporate rates on any undistributed "real
          estate  investment trust taxable income,"  including our undistributed
          net capital gains.

     o    If our alternative  minimum taxable income exceeds our taxable income,
          we may be  subject to the  corporate  alternative  minimum  tax on our
          items of tax preference.

     o    If  we  have  net  income  from  the  sale  or  other  disposition  of
          "foreclosure property" that is held primarily for sale to customers in
          the  ordinary  course of business or other  nonqualifying  income from
          foreclosure  property,  we will be  subject  to tax on this net income
          from foreclosure property at the highest regular corporate rate, which
          is  currently  35%.  REITs may elect to operate  foreclosure  property
          which is, in general, property acquired or reduced to possession after
          a default or imminent  default on a loan secured by the property or on
          a lease of the property. We anticipate operating several facilities as
          foreclosure  property in the manner prescribed by applicable  Internal
          Revenue Code provisions.

     o    If we have net income from prohibited transactions, including sales or
          other dispositions of inventory or property held primarily for sale to
          customers in the ordinary  course of business  other than  foreclosure
          property, we will be subject to tax on this income at a 100% rate.

                                       14
<PAGE>

     o    If we fail to  satisfy  the 75%  gross  income  test or the 95%  gross
          income  test   discussed   below,   but   nonetheless   maintain   our
          qualification  as a REIT,  we will be subject to tax at a 100% rate on
          the  greater  of the  amount by which we fail the 75% or the 95% test,
          multiplied by a fraction intended to reflect our profitability.

     o    If we fail to distribute for any calendar year at least the sum of 85%
          of our REIT  ordinary  income for that year,  95% of our REIT  capital
          gain net income for that year,  and any  undistributed  taxable income
          from  prior  periods,  we will be  subject  to a 4% excise  tax on the
          excess  of  the  required   distribution  over  the  amounts  actually
          distributed.

     o    If we acquire an asset from a corporation  in a  transaction  in which
          our basis in the asset is  determined by reference to the basis of the
          asset in the hands of a present  or  former C  corporation,  and if we
          subsequently  recognize  gain on the  disposition of this asset during
          the ten-year period beginning on the date on which the asset ceased to
          be owned  by the C  corporation,  then we will pay tax at the  highest
          regular  corporate tax rate,  which is currently 35%, on the lesser of
          the  excess  of  the  fair  market  value  of  the  asset  over  the C
          corporation's  basis in the asset on the date the  asset  ceased to be
          owned by the C corporation, or the gain recognized in the disposition.

         If we invest in properties in foreign countries, our profits from those
investments  will  generally  be subject  to tax in the  countries  where  those
properties  are located.  The nature and amount of this  taxation will depend on
the laws of the countries where the properties are located.  If we operate as we
currently intend, then we will distribute our taxable income to our shareholders
and we will not pay federal income tax, and thus we generally cannot recover the
cost of foreign taxes imposed on our foreign investments by claiming foreign tax
credits  against our federal income tax liability.  Also, we cannot pass through
to our shareholders any foreign tax credits.

         If we fail to qualify  for  federal  income  taxation  as a REIT in any
taxable  year,  then we will be subject to federal  tax in the same manner as an
ordinary corporation.  Distributions to our shareholders in any year in which we
fail to qualify as a REIT will not be deductible,  nor will these  distributions
be  required  to be made.  In that  event,  to the  extent  of our  current  and
accumulated  earnings and profits, all distributions to our shareholders will be
taxable as ordinary  dividend income and, subject to limitations in the Internal
Revenue  Code,  will  be  eligible  for the  dividends  received  deduction  for
corporate recipients. Also in that event, we will generally be disqualified from
federal  income  taxation  as a  REIT  for  the  four  taxable  years  following
disqualification.  Failure to qualify for federal income  taxation as a REIT for
even  one  year  could  result  in our  incurring  substantial  indebtedness  or
liquidating   substantial   investments   in   order   to  pay   the   resulting
corporate-level taxes.

REIT Qualification Requirements

         General  Requirements.  Section  856(a) of the  Internal  Revenue  Code
defines a REIT as a corporation, trust or association:

         (1) that is managed by one or more trustees or directors;

         (2) the  beneficial  ownership of which is  evidenced  by  transferable
shares or by transferable certificates of beneficial interest;

         (3) that would be  taxable,  but for  Sections  856  through 859 of the
Internal Revenue Code, as an ordinary domestic corporation;

         (4) that is not a financial institution or an insurance company subject
to special provisions of the Internal Revenue Code;

         (5) the beneficial ownership of which is held by 100 or more persons;

                                       15
<PAGE>

         (6) that is not "closely  held" as defined  under the personal  holding
company stock ownership test, as described below; and

         (7) that meets other tests regarding income,  assets and distributions,
all as described below.

Section 856(b) of the Internal Revenue Code provides that conditions (1) to (4),
inclusive,  must be met during the entire  taxable year and that  condition  (5)
must be met during at least 335 days of a taxable year of 12 months, or during a
pro rata part of a taxable year of less than 12 months. Section 856(h)(2) of the
Internal  Revenue Code provides that  conditions (5) and (6) need not be met for
our first taxable year as a REIT. We believe that we have  satisfied  conditions
(1) to (6), inclusive,  during each of the requisite periods ending on or before
December 31, 1999,  and that we will  continue to satisfy  those  conditions  in
future taxable years. There can, however, be no assurance in this regard.

         By reason of condition (6) above, we will fail to qualify as a REIT for
a taxable  year if at any time during the last half of the year more than 50% in
value of our outstanding shares is owned directly or indirectly by five or fewer
individuals.  To help  comply  with  condition  (6),  our  declaration  of trust
contains  provisions  restricting  transfers of our shares.  In addition,  if we
comply with applicable  Treasury  regulations for  ascertaining the ownership of
our outstanding  shares and do not know, or by exercising  reasonable  diligence
would not have known,  that we failed  condition (6), then we will be treated as
satisfying  condition  (6).  Also,  our failure to comply with these  applicable
Treasury  regulations for ascertaining  ownership of our outstanding  shares may
result  in  a  penalty  of  $25,000,  or  $50,000  for  intentional  violations.
Accordingly, we intend to comply with these Treasury regulations, and to request
annually  from  record  holders  of   significant   percentages  of  our  shares
information  regarding the  ownership of our shares.  Under our  declaration  of
trust,   our  shareholders  are  required  to  respond  to  these  requests  for
information.

         For purposes of condition (6) above, shares in a REIT held by a pension
trust are  treated as held  directly  by the pension  trust's  beneficiaries  in
proportion to their actuarial interests in the pension trust. Consequently, five
or fewer  pension  trusts could own more than 50% of the  interests in an entity
without  jeopardizing  that entity's federal income tax qualification as a REIT.
However,  as discussed  below, if a REIT is a "pension-held  REIT," each pension
trust owning more than 10% of the REIT's shares by value generally will be taxed
on a portion of the dividends received from the REIT, based on the ratio of:

         (1) the REIT's gross income for the year that would be unrelated  trade
or business income if the REIT were a qualified pension trust, to

         (2) the REIT's total gross income for the year.

         Our Wholly-Owned Subsidiaries and Our Investments through Partnerships.
Section 856(i) of the Internal  Revenue Code provides that any corporation  100%
of whose stock is held by a REIT is a qualified REIT subsidiary and shall not be
treated as a separate corporation.  The assets, liabilities and items of income,
deduction and credit of a qualified  REIT  subsidiary are treated as the REIT's.
We believe that each of our direct and indirect  wholly-owned  subsidiaries will
either be a qualified  REIT  subsidiary  within the meaning of Section 856(i) of
the Internal Revenue Code, or a noncorporate  entity that for federal income tax
purposes  is not treated as separate  from its owner  under  regulations  issued
under  Section  7701 of the Internal  Revenue  Code.  Thus,  in applying all the
federal income tax REIT  qualification  requirements  described in this summary,
all assets,  liabilities and items of income, deduction and credit of our direct
and indirect wholly-owned subsidiaries are treated as ours.

         We may invest in real  estate  through  one or more  limited or general
partnerships or limited liability companies that are treated as partnerships for
federal  income  tax  purposes.  In the case of a REIT  that is a  partner  in a
partnership,  regulations  under the Internal  Revenue Code  provide  that,  for
purposes  of the REIT  qualification  requirements  regarding  income and assets
discussed below, the REIT is deemed to own its proportionate share of the assets
of the partnership corresponding to the REIT's proportionate capital interest in

                                       16
<PAGE>

the  partnership  and is deemed to be entitled to the income of the  partnership
attributable to this proportionate share. In addition,  for these purposes,  the
character of the assets and gross income of the partnership generally retain the
same character in the hands of the REIT. Accordingly, our proportionate share of
the assets, liabilities, and items of income of each partnership in which we are
a partner is treated as ours for  purposes  of the income  tests and asset tests
discussed  below.  In  contrast,  for purposes of the  distribution  requirement
discussed below, we must take into account as a partner our  distributive  share
of the  partnership's  income as determined under the general federal income tax
rules governing  partners and partnerships under Sections 701 through 777 of the
Internal Revenue Code.

         Income Tests. There are two gross income requirements for qualification
as a REIT under the Internal Revenue Code:

     o    At least 75% of our gross income, excluding gross income from sales or
          other  dispositions  of  property  held  primarily  for sale,  must be
          derived from investments  relating to real property,  including "rents
          from real  property"  as defined  under  Section  856 of the  Internal
          Revenue Code,  mortgages on real  property,  or shares in other REITs.
          When we receive new capital in exchange  for our shares or in a public
          offering of five-year or longer debt instruments,  income attributable
          to the  temporary  investment  of this new  capital in stock or a debt
          instrument,  if received or accrued  within one year of our receipt of
          the new capital,  is generally  also  qualifying  income under the 75%
          test.

     o    At least 95% of our gross income, excluding gross income from sales or
          other  dispositions  of  property  held  primarily  for sale,  must be
          derived  from a  combination  of items of real  property  income  that
          satisfy the 75% test described above,  dividends,  interest,  payments
          under  interest  rate  swap  or  cap  agreements,   options,   futures
          contracts,  forward rate agreements, or similar financial instruments,
          and gains from the sale or disposition of stock,  securities,  or real
          property.

For  purposes  of  these  two  requirements,   income  derived  from  a  "shared
appreciation  provision"  in a  mortgage  loan  is  generally  treated  as  gain
recognized on the sale of the property to which it relates. Although we will use
our best efforts to ensure that the income  generated by our investments will be
of a type which satisfies both the 75% and 95% gross income tests,  there can be
no assurance in this regard.

         In order to qualify as "rents from real property"  under Section 856 of
the Internal Revenue Code, several requirements must be met:

     o    The amount of rent received  generally must not be based on the income
          or profits of any person, but may be based on receipts or sales.

     o    Rents do not  qualify if the REIT owns 10% or more by vote or value of
          the tenant,  whether  directly  or after  application  of  attribution
          rules.  While we intend  not to lease  property  to any party if rents
          from that  property  would not  qualify as rents  from real  property,
          application  of the 10%  ownership  rule  is  dependent  upon  complex
          attribution  rules and  circumstances  that may be beyond our control.
          For example,  an unaffiliated  third party's ownership  directly or by
          attribution  of 10% or more by value of our shares,  or 10% or more by
          value of HRPT Properties Trust's shares for so long as HRPT Properties
          Trust  owns 10% or more by value of us, as well as 10% or more by vote
          or value of the  stock of one of our  lessees,  would  result  in that
          lessee's  rents  not  qualifying  as rents  from  real  property.  Our
          declaration of trust  disallows  transfers or purported  acquisitions,
          directly  or by  attribution,  of our  shares  that  could  result  in
          disqualification as a REIT under the Internal Revenue Code and permits
          our  trustees  to  repurchase  the shares to the extent  necessary  to
          maintain  our  status  as a REIT  under  the  Internal  Revenue  Code.
          Nevertheless,  there can be no assurance that these  provisions in our
          declaration  of trust will be  effective  to prevent REIT status under
          the Internal Revenue Code from being  jeopardized under the 10% lessee
          affiliate rule. Furthermore, there can be no assurance that we will be
          able  to  monitor  and  enforce  these  restrictions,   nor  will  our

                                       17
<PAGE>

          shareholders necessarily be aware of ownership of shares attributed to
          them under the Internal Revenue Code's attribution rules.

     o    In order  for rents to  qualify,  we  generally  must not  manage  the
          property or furnish or render services to the tenants of the property,
          except  through  an  independent  contractor  from  whom we  derive no
          income.  There  is an  exception  to this  rule  permitting  a REIT to
          perform  customary  tenant  services  of the sort  which a  tax-exempt
          organization  could  perform  without  being  considered in receipt of
          "unrelated business taxable income" as defined in Section 512(b)(3) of
          the  Internal  Revenue  Code.  In  addition,  a de  minimis  amount of
          noncustomary  services will not disqualify  income as "rents from real
          property" so long as the value of the impermissible  services does not
          exceed 1% of the gross income from the property.

     o    If rent  attributable to personal property leased in connection with a
          lease of real property is 15% or less of the total rent received under
          the  lease,  then the rent  attributable  to  personal  property  will
          qualify  as  rents  from  real  property;  if this  15%  threshold  is
          exceeded,  the rent  attributable  to  personal  property  will not so
          qualify.  The  portion of rental  income  treated as  attributable  to
          personal  property  is  determined  according  to the ratio of the tax
          basis of the personal  property to the total tax basis of the real and
          personal  property which is rented.  For taxable years after 2000, the
          ratio will be  determined  by reference to fair market  values  rather
          than tax bases.

We  believe  that all or  substantially  all our rents have  qualified  and will
qualify as rents from real  property for purposes of Section 856 of the Internal
Revenue Code.

         In order to qualify as mortgage  interest on real property for purposes
of the 75% test,  interest  must  derive  from a mortgage  loan  secured by real
property with a fair market value,  at the time the loan is made, at least equal
to the amount of the loan.  If the amount of the loan  exceeds  the fair  market
value of the real  property,  the  interest  will be  treated as  interest  on a
mortgage loan in a ratio equal to the ratio of the fair market value of the real
property to the total amount of the mortgage loan.

         Other than sales of  foreclosure  property,  any gain we realize on the
sale of property held as inventory or other  property held primarily for sale to
customers  in the ordinary  course of business  will be treated as income from a
prohibited  transaction  that is subject to a penalty  tax at a 100% rate.  This
prohibited  transaction  income also may have an adverse effect upon our ability
to  satisfy  the  75%  and  95%  gross  income  tests  for  federal  income  tax
qualification  as a REIT. We cannot provide  assurances as to whether or not the
IRS might successfully assert that one or more of our dispositions is subject to
the 100% penalty tax.  However,  we believe that  dispositions of assets that we
might make will not be subject to the 100% penalty tax, because we intend to:

     o    own  our  assets  for  investment  with a  view  to  long-term  income
          production and capital appreciation;

     o    engage  in the  business  of  developing,  owning  and  operating  our
          existing  properties and acquiring,  developing,  owning and operating
          new properties; and

     o    make  occasional  dispositions  of  our  assets  consistent  with  our
          long-term investment objectives.

         If we fail to satisfy one or both of the 75% or 95% gross  income tests
for any taxable year, we may nevertheless qualify as a REIT for that year if:

     o    our failure to meet the test was due to  reasonable  cause and not due
          to willful neglect;

     o    we report the nature and amount of each item of our income included in
          the 75% or 95% gross  income tests for that taxable year on a schedule
          attached to our tax return; and

     o    any  incorrect  information  on the schedule was not due to fraud with
          intent to evade tax.

                                       18
<PAGE>

It is impossible to state whether in all  circumstances  we would be entitled to
the benefit of this relief  provision  for the 75% and 95% gross  income  tests.
Even if this relief  provision did apply, a special tax equal to 100% is imposed
upon the  greater of the amount by which we failed the 75% test or the 95% test,
multiplied by a fraction intended to reflect our profitability.

         Asset Tests. At the close of each quarter of each taxable year, we must
also satisfy three percentage tests relating to the nature of our assets:

     o    At least 75% of our total assets must  consist of real estate  assets,
          cash and cash items, shares in other REITs, government securities, and
          stock or debt instruments  purchased with proceeds of a stock offering
          or an  offering  of our debt with a term of at least five  years,  but
          only  for the  one-year  period  commencing  with our  receipt  of the
          offering proceeds.

     o    Not more than 25% of our total assets may be represented by securities
          other than those  securities that count favorably toward the preceding
          75% asset test.

     o    Of the  investments  included in the  preceding  25% asset class,  the
          value of any one issuer's  securities that we own may not exceed 5% of
          the value of our total assets, and we may not own more than 10% of any
          one non-REIT issuer's outstanding voting securities. For taxable years
          after  2000,  we may not own more than 10% of the vote or value of any
          one non-REIT issuer's  outstanding  securities,  unless that issuer is
          our taxable  REIT  subsidiary  or the  securities  are  straight  debt
          securities.

When a failure to satisfy the above asset tests results from an  acquisition  of
securities  or other  property  during a quarter,  the  failure  can be cured by
disposition of sufficient nonqualifying assets within 30 days after the close of
that  quarter.  We  intend to  maintain  records  of the value of our  assets to
document our compliance with the above three asset tests, and to take actions as
may be required  to cure any  failure to satisfy the tests  within 30 days after
the close of any quarter.

         Annual Distribution Requirements. In order to qualify for taxation as a
REIT  under  the  Internal   Revenue  Code,  we  are  required  to  make  annual
distributions other than capital gain dividends to our shareholders in an amount
at least equal to the excess of:

         (A)  the  sum of  95% of our  "real  estate  investment  trust  taxable
income," as defined in Section 857 of the  Internal  Revenue  Code,  computed by
excluding any net capital gain and before taking into account any dividends paid
deduction  for which we are  eligible,  and 95% of our net income  after tax, if
any, from property received in foreclosure, over

         (B) the sum of our  qualifying  noncash  income,  e.g.,  imputed rental
income or income from transactions inadvertently failing to qualify as like-kind
exchanges.

For our taxable years after 2000, the preceding 95%  percentages  are reduced to
90%. The distributions must be paid in the taxable year to which they relate, or
in the following  taxable year if declared  before we timely file our tax return
for the  earlier  taxable  year  and if  paid on or  before  the  first  regular
distribution  payment  after that  declaration.  Dividends  declared in October,
November,  or December and paid during the following  January will be treated as
having been both paid and received on December 31 of the prior  taxable  year. A
distribution  which is not pro rata within a class of our  beneficial  interests
entitled  to a  distribution,  or which is not  consistent  with the  rights  to
distributions  among our  classes of  beneficial  interests,  is a  preferential
distribution  that  is  not  taken  into   consideration  for  purposes  of  the
distribution  requirements,  and  accordingly  the  payment  of  a  preferential
distribution  could  affect our ability to meet the  distribution  requirements.
Taking  into  account  our   distribution   policies,   including  the  dividend
reinvestment  plan  we have  adopted,  we  expect  that we  will  not  make  any
preferential  distributions.  The distribution requirements may be waived by the
IRS if a REIT establishes that it failed to meet them by reason of distributions
previously made to meet the  requirements of the

                                       19
<PAGE>

4% excise tax discussed  below.  To the extent that we do not  distribute all of
our net capital gain and all of our real estate investment trust taxable income,
as adjusted, we will be subject to tax on undistributed amounts.

         In  addition,  we will be  subject  to a 4% excise tax to the extent we
fail within a calendar year to make required  distributions  to our shareholders
of 85% of our  ordinary  income and 95% of our capital  gain net income plus the
excess,  if any, of the  "grossed up required  distribution"  for the  preceding
calendar year over the amount treated as distributed for that preceding calendar
year.  For this  purpose,  the term "grossed up required  distribution"  for any
calendar  year is the sum of our taxable  income for the  calendar  year without
regard to the deduction  for  dividends  paid and all amounts from earlier years
that are not treated as having been distributed under the provision.

         If we do not have  enough cash or other  liquid  assets to meet the 95%
distribution  requirements,  we may find it necessary to arrange for new debt or
equity financing to provide funds for required  distributions,  or else our REIT
status for federal income tax purposes could be  jeopardized.  We can provide no
assurance  that  financing  would be available  for these  purposes on favorable
terms.

         If we fail to distribute  sufficient  dividends for any year, we may be
able to rectify this failure by paying "deficiency dividends" to shareholders in
a later year.  These  deficiency  dividends may be included in our deduction for
dividends  paid for the earlier  year,  but an interest  charge would be imposed
upon us for the delay in  distribution.  Although  we may be able to avoid being
taxed on amounts distributed as deficiency dividends,  we will remain liable for
the 4% excise tax discussed above.

         Recent Federal Taxation  Changes.  The Tax Relief Extension Act of 1999
was enacted late in 1999 and is  effective  for taxable  years after 2000.  This
legislation  contained  several  tax  provisions  regarding  REITs,  including a
reduction  of the annual  distribution  requirement  for real estate  investment
trust taxable income from 95% to 90%, as mentioned  above.  The Act also changed
the 10% voting  securities  test under  current law to a 10% vote or value test.
Thus,  subject to exceptions,  a REIT will no longer be allowed to own more that
10% by vote or value of the outstanding  securities of any issuer,  other than a
qualified REIT subsidiary or another REIT.  Another  exception to this new test,
which is also an exception to the 5% asset test under current law, allows a REIT
to own any or all of the  securities of an electing  "taxable REIT  subsidiary,"
provided that no more than 20% of the REIT's assets is  represented by the stock
or  securities  of taxable  REIT  subsidiaries.  A taxable REIT  subsidiary  can
perform noncustomary  services for tenants of a REIT without disqualifying rents
received  from the tenants for purposes of the REIT's gross income tests and can
also undertake third-party  management and development activities and activities
that are not related to real estate.  A taxable REIT subsidiary  cannot directly
or  indirectly  operate  or  manage a  health  care  facility.  A  taxable  REIT
subsidiary  will be taxed as a subchapter C  corporation  but will be subject to
earnings  stripping  limitations  on the  deductibility  of interest paid to the
REIT. In addition, a REIT will be subject to a 100% excise tax on certain excess
amounts to ensure that:

     o    tenants who pay a taxable REIT  subsidiary for services are charged an
          arm's length amount by the taxable REIT subsidiary for these services;

     o    shared  expenses  of a  REIT  and  its  taxable  REIT  subsidiary  are
          allocated fairly between the two; and

     o    interest paid by a taxable REIT subsidiary to the REIT that owns it is
          commercially reasonable.

         In connection with foreclosure  actions, we anticipate operating health
care properties  through  taxable  subsidiaries in which we own less than 10% of
the vote but most of the value, all in accordance with current laws. For taxable
years after 2000, we will  restructure our affairs as appropriate to comply with
the requirements of applicable law.

                                       20

Depreciation and Federal Income Tax Treatment of Leases

         Our initial tax bases in our assets will  generally be our  acquisition
cost. We will generally  depreciate our real property on a  straight-line  basis
over 40 years  and our  personal  property  over 12  years.  These  depreciation
schedules may vary for properties that we acquire through  tax-free or carryover
basis acquisitions.

         The initial tax bases and depreciation schedules for our assets we held
immediately  after we ceased to be wholly-owned by HRPT Properties Trust depends
upon whether the deemed exchange that resulted from the spin-off was an exchange
under  Section  351(a) of the  Internal  Revenue  Code.  We believe that Section
351(a)  treatment was appropriate,  and we carried over HRPT Properties  Trust's
tax basis and  depreciation  schedule in each of the  assets,  and to the extent
that HRPT Properties  Trust  recognized gain on an asset in the deemed exchange,
we have  additional  tax basis in that  asset  which we  depreciate  in the same
manner as we depreciate newly purchased assets.  In contrast,  if Section 351(a)
treatment was not appropriate for the deemed  exchange,  then we will be treated
as though we  acquired  all our  assets at the time of the  spin-off  in a fully
taxable acquisition, thereby acquiring aggregate tax bases in these assets equal
to the  aggregate  amount  realized  by  HRPT  Properties  Trust  in the  deemed
exchange,  and we will  depreciate  these  tax  bases in the same  manner  as we
depreciate newly purchased assets. We believe,  and Sullivan & Worcester LLP has
opined, that it is likely that the deemed exchange was an exchange under Section
351(a),  and we  will  perform  all  our tax  reporting  accordingly.  We may be
required to amend these tax reports,  including those sent to our  shareholders,
if the IRS  successfully  challenges our position that the deemed exchange is an
exchange  under  Section  351(a).  We  intend  to comply  with the  annual  REIT
distribution  requirements  regardless  of whether  the deemed  exchange  was an
exchange under Section 351(a).

         We will be entitled to depreciation deductions from our facilities only
if we  are  treated  for  federal  income  tax  purposes  as  the  owner  of the
facilities.  This means that the leases of the facilities must be classified for
federal  income tax purposes as true  leases,  rather than as sales or financing
arrangements,  and we believe this to be the case. In the case of sale-leaseback
arrangements, the IRS could assert that we realized prepaid rental income in the
year of purchase to the extent that the value of a leased property,  at the time
of purchase,  exceeded the purchase  price for that  property.  While we believe
that the  value  of  leased  property  at the time of  purchase  did not  exceed
purchase  prices,  because  of the lack of clear  precedent  we  cannot  provide
assurances  as to whether the IRS might  successfully  assert the  existence  of
prepaid rental income in any of our sale-leaseback transactions.

         Additionally,  Section 467 of the Internal Revenue Code, which concerns
leases with increasing rents, may apply to those of our leases which provide for
rents that  increase  from one period to the next.  Section 467 of the  Internal
Revenue Code  provides that in the case of a so-called  "disqualified  leaseback
agreement" rental income must be accrued at a constant rate. Where constant rent
accrual is required,  we could recognize rental income from a lease in excess of
cash  rents  and,  as a result,  encounter  difficulty  in  meeting  the  annual
distribution  requirement.  Disqualified  leaseback agreements include leaseback
transactions  where a principal purpose for providing  increasing rent under the
agreement  is the  avoidance of federal  income tax.  Recently  issued  Treasury
regulations  provide  that  rents  will not be  treated  as  increasing  for tax
avoidance  purposes  where the  increases  are based upon a fixed  percentage of
lessee  receipts.  Therefore,  the additional rent provisions in our leases that
are based on a fixed  percentage of lessee receipts  generally  should not cause
the leases to be disqualified leaseback agreements under Section 467.

Taxation of U.S. Shareholders

         As long as we qualify as a REIT for  federal  income  tax  purposes,  a
distribution to our U.S. shareholders that we do not designate as a capital gain
dividend will be treated as an ordinary income dividend to the extent that it is
made out of current or accumulated earnings and profits.  Distributions made out
of our current or accumulated earnings and profits that we properly designate as
capital gain  dividends will be taxed as long-term  capital gains,  as discussed
below,  to the extent  they do not exceed  our actual net  capital  gain for the
taxable

                                       21
<PAGE>

year. However,  corporate shareholders may be required to treat up to 20% of any
capital  gain  dividend as ordinary  income  under  Section 291 of the  Internal
Revenue Code.

         In  addition,  we may elect to retain net capital gain income and treat
it as constructively distributed. In that case:

         (1) we will be taxed at regular  corporate  capital  gains tax rates on
retained amounts,

         (2) each U.S. shareholder will be taxed on its designated proportionate
share of our retained net capital  gains as though that amount were  distributed
and designated a capital gain dividend,

         (3) each U.S.  shareholder  will  receive a credit  for its  designated
proportionate share of the tax that we pay,

         (4) each U.S.  shareholder  will  increase  its  adjusted  basis in our
shares by the excess of the amount of its proportionate  share of these retained
net capital gains over its proportionate share of this tax that we pay, and

         (5)  both we and our  corporate  shareholders  will  make  commensurate
adjustments  in our  respective  earnings  and profits  for  federal  income tax
purposes.

If we elect to retain our net capital gains in this fashion,  we will notify our
U.S. shareholders of the relevant tax information within 60 days after the close
of the affected taxable year.

         For  noncorporate  U.S.  shareholders,   long-term  capital  gains  are
generally  taxed  at  maximum  rates of 20% or 25%,  depending  upon the type of
property  disposed of and the previously  claimed  depreciation  with respect to
this  property.  If for any taxable year we designate as capital gain  dividends
any portion of the  dividends  paid or made  available  for the year to our U.S.
shareholders,  including  our  retained  capital  gains  treated as capital gain
dividends,  then the portion of the capital gain  dividends so  designated  that
will be  allocated  to the  holders of a  particular  class of shares  will on a
percentage  basis equal the ratio of the amount of the total  dividends  paid or
made  available for the year to the holders of that class of shares to the total
dividends  paid or made  available for the year to holders of all classes of our
shares.  We will  similarly  designate  the portion of any capital gain dividend
that is to be taxed to  noncorporate  U.S.  shareholders at the maximum rates of
20% or 25% so that the  designations  will be proportional  among all classes of
our shares.

         Distributions in excess of current or accumulated  earnings and profits
will not be taxable to a U.S.  shareholder to the extent that they do not exceed
the shareholder's  adjusted basis in the shareholder's  shares,  but will reduce
the  shareholder's  basis in those  shares.  To the  extent  that  these  excess
distributions  exceed the adjusted basis of a U.S.  shareholder's  shares,  they
will be included in income as capital gain,  with long-term gain generally taxed
to noncorporate U.S.  shareholders at a maximum rate of 20%. No U.S. shareholder
may include on his federal income tax return any of our net operating  losses or
any of our capital losses.

         Dividends that we declare in October, November or December of a taxable
year to U.S.  shareholders of record on a date in those months will be deemed to
have been received by shareholders on December 31 of that taxable year, provided
we actually pay these dividends during the following  January.  Also, items that
are treated  differently for regular and alternative minimum tax purposes are to
be allocated  between a REIT and its  shareholders  under  Treasury  regulations
which are to be prescribed.  It is possible that these Treasury regulations will
require tax preference items to be allocated to our shareholders with respect to
any accelerated depreciation or other tax preference items that we claim.

         A U.S.  shareholder's  sale or  exchange  of our shares  will result in
recognition  of gain or loss in an amount  equal to the  difference  between the
amount  realized  and the  shareholder's  adjusted  basis in the shares  sold or
exchanged. This gain or loss will be capital gain or loss, and will be long-term
capital gain or loss if the

                                       22
<PAGE>

shareholder's  holding period in the shares  exceeds one year. In addition,  any
loss upon a sale or  exchange  of our  shares  held for six  months or less will
generally be treated as a long-term  capital loss to the extent of our long-term
capital gain dividends during the holding period.

         Noncorporate  U.S.  shareholders  who  borrow  funds to  finance  their
acquisition  of our shares could be limited in the amount of deductions  allowed
for the interest paid on the indebtedness incurred.  Under Section 163(d) of the
Internal  Revenue  Code,  interest paid or accrued on  indebtedness  incurred or
continued  to  purchase  or carry  property  held for  investment  is  generally
deductible  only to the extent of the investor's net investment  income.  A U.S.
shareholder's  net  investment  income will  include  ordinary  income  dividend
distributions  received from us and, if an  appropriate  election is made by the
shareholder,  capital gain dividend  distributions  received  from us;  however,
distributions treated as a nontaxable return of the shareholder's basis will not
enter into the computation of net investment income.

Taxation of Tax-Exempt Shareholders

         In Revenue Ruling 66-106,  the IRS ruled that amounts  distributed by a
REIT to a tax-exempt  employees'  pension  trust did not  constitute  "unrelated
business  taxable  income,"  even  though  the REIT may have  financed  some its
activities  with   acquisition   indebtedness.   Although  revenue  rulings  are
interpretive  in nature and subject to  revocation or  modification  by the IRS,
based  upon  the  analysis  and  conclusion  of  Revenue   Ruling  66-106,   our
distributions made to shareholders that are tax-exempt pension plans, individual
retirement  accounts,   or  other  qualifying  tax-exempt  entities  should  not
constitute  unrelated  business  taxable  income,  unless  the  shareholder  has
financed its acquisition of our shares with  "acquisition  indebtedness"  within
the meaning of the Internal Revenue Code.

         Special rules apply to tax-exempt pension trusts,  including  so-called
401(k) plans but excluding individual  retirement accounts or government pension
plans,  that own more  than  10% by value of a  "pension-held  REIT" at any time
during a taxable  year.  The pension trust may be required to treat a percentage
of all  dividends  received  from  the  pension-held  REIT  during  the  year as
unrelated business taxable income. This percentage is equal to the ratio of:

         (1) the  pension-held  REIT's gross income  derived from the conduct of
unrelated trades or businesses,  determined as if the  pension-held  REIT were a
tax-exempt pension fund, less direct expenses related to that income, to

         (2) the pension-held REIT's gross income from all sources,  less direct
expenses related to that income,

except that this percentage shall be deemed to be zero unless it would otherwise
equal or exceed 5%. A REIT is a pension-held REIT if:

     o    the REIT is "predominantly held" by tax-exempt pension trusts, and

     o    the REIT would  otherwise fail to satisfy the "closely held" ownership
          requirement  discussed  above if the stock or beneficial  interests in
          the REIT held by  tax-exempt  pension  trusts  were  viewed as held by
          tax-exempt   pension   trusts   rather   than  by   their   respective
          beneficiaries.

A REIT is  predominantly  held by  tax-exempt  pension  trusts  if at least  one
tax-exempt  pension  trust  owns more than 25% by value of the  REIT's  stock or
beneficial  interests,  or if one or more tax-exempt pension trusts, each owning
more than 10% by value of the REIT's stock or beneficial  interests,  own in the
aggregate  more than 50% by value of the REIT's stock or  beneficial  interests.
Because of the  restrictions in our declaration of trust regarding the ownership
concentration  of our  shares,  we  believe  that we are not and  will  not be a
pension-held  REIT.  However,  because our shares are publicly traded, we cannot
completely control whether or not we are or will become a pension-held REIT.

Taxation of Non-U.S. Shareholders

         The rules  governing  the United  States  federal  income  taxation  of
non-U.S. shareholders are complex, and the following discussion is intended only
as a summary of these rules. If you are a non-U.S.  shareholder,  we urge you to
consult  with your own tax  advisor to  determine  the  impact of United  States
federal, state, local, and foreign tax laws, including any tax return filing and
other reporting requirements, with respect to your investment in our shares.

         In general,  a non-U.S.  shareholder  will be subject to regular United
States federal income tax in the same manner as a U.S.  shareholder with respect
to its investment in our shares if that investment is effectively connected with
the non-U.S.  shareholder's conduct of a trade or business in the United States.
In addition, a corporate non-U.S. shareholder that receives income that is or is
deemed  effectively  connected with a trade or business in the United States may
also be subject to the 30% branch  profits tax under Section 884 of the Internal
Revenue  Code,  which is payable in addition to regular  United  States  federal
corporate  income  tax.  The  balance of this  discussion  on the United  States
federal income taxation of non-U.S.  shareholders  addresses only those non-U.S.
shareholders  whose  investment in our shares is not effectively  connected with
the conduct of a trade or business in the United States.

         A distribution by us to a non-U.S. shareholder that is not attributable
to gain from the sale or exchange of a United States real property  interest and
that is not designated as a capital gain dividend will be treated as an ordinary
income  dividend  to the extent  that it is made out of  current or  accumulated
earnings and profits.  A distribution  of this type will generally be subject to
United  States  federal  income tax and  withholding  at the rate of 30%, or the
lower rate that may be specified by a tax treaty if the non-U.S. shareholder has
in the manner  prescribed by the IRS  demonstrated  its  entitlement to benefits
under a tax treaty.  Because we cannot  determine  our  current and  accumulated
earnings and profits until the end of the taxable year,  withholding at the rate
of 30% or  applicable  lower  treaty rate will be imposed on the gross amount of
any  distribution to a non-U.S.  shareholder that we make and do not designate a
capital gain dividend.  Notwithstanding  this  withholding on  distributions  in
excess of our current and accumulated earnings and profits,  these distributions
are a  nontaxable  return of capital  to the extent  that they do not exceed the
non-U.S.  shareholder's  adjusted basis in our shares, and the nontaxable return
of capital will reduce the adjusted  basis in these  shares.  To the extent that
distributions  in excess of current and accumulated  earnings and profits exceed
the non-U.S.  shareholder's adjusted basis in our shares, the distributions will
give rise to tax  liability  if the  non-U.S.  shareholder  would  otherwise  be
subject  to tax on any gain  from  the sale or  exchange  of  these  shares,  as
discussed  below.  A  non-U.S.  shareholder  may seek a  refund  from the IRS of
amounts  withheld  on  distributions  to  him  in  excess  of  our  current  and
accumulated earnings and profits.

         For any year in  which we  qualify  as a REIT,  distributions  that are
attributable  to gain from the sale or exchange of a United States real property
interest  are taxed to a non-U.S.  shareholder  as if these  distributions  were
gains  effectively  connected  with a trade or  business  in the  United  States
conducted by the non-U.S. shareholder.  Accordingly, a non-U.S. shareholder will
be taxed on these amounts at the normal capital gain rates  applicable to a U.S.
shareholder,  subject to any applicable alternative minimum tax and to a special
alternative  minimum  tax in the  case of  nonresident  alien  individuals;  the
non-U.S. shareholder will be required to file a United States federal income tax
return  reporting  these amounts,  even if applicable  withholding is imposed as
described  below;  and corporate  non-U.S.  shareholders  may owe the 30% branch
profits tax under  Section 884 of the Internal  Revenue Code in respect of these
amounts.  We will  be  required  to  withhold  from  distributions  to  non-U.S.
shareholders,  and  remit  to  the  IRS,  35%  of  the  maximum  amount  of  any
distribution  that could be designated as a capital gain dividend.  In addition,
for purposes of this  withholding  rule, if we designate prior  distributions as
capital gain dividends,  then subsequent  distributions  up to the amount of the
designated prior  distributions  will be treated as capital gain dividends.  The
amount of any tax  withheld is  creditable  against the  non-U.S.  shareholder's
United States federal  income tax  liability,  and any amount of tax withheld in
excess of that tax liability may be refunded  provided that an appropriate claim
for  refund is filed  with the IRS.  If for any  taxable  year we  designate  as
capital gain  dividends any portion of the dividends  paid or made available for
the year to our  shareholders,  including our retained  capital gains treated as
capital  gain

                                       24
<PAGE>

dividends,  then the portion of the capital gain  dividends so  designated  that
will be  allocated  to the  holders of a  particular  class of shares  will on a
percentage  basis equal the ratio of the amount of the total  dividends  paid or
made  available for the year to the holders of that class of shares to the total
dividends  paid or made  available for the year to holders of all classes of our
shares.

         Tax   treaties   may  reduce  the   withholding   obligations   on  our
distributions.   Under  some  treaties,   however,  rates  below  30%  generally
applicable to ordinary income dividends from United States  corporations may not
apply to ordinary income dividends from a REIT. If the amount of tax withheld by
us  with  respect  to a  distribution  to a  non-U.S.  shareholder  exceeds  the
shareholder's  United States  federal  income tax liability  with respect to the
distribution,  the non-U.S. shareholder may file for a refund of the excess from
the IRS. In this regard,  note that the 35% withholding tax rate on capital gain
dividends  corresponds  to the maximum  income tax rate  applicable to corporate
non-U.S.  shareholders  but is  higher  than  the 20% and 25%  maximum  rates on
capital  gains  generally  applicable  to  noncorporate  non-U.S.  shareholders.
Generally  effective with respect to distributions paid after December 31, 2000,
new Treasury regulations alter the information  reporting and backup withholding
rules applicable to non-U.S. shareholders and provide presumptions under which a
non-U.S.  shareholder is subject to backup withholding and information reporting
until we or the applicable  withholding  agent receives  certification  from the
shareholder  of its  non-U.S.  shareholder  status.  In  some  instances,  these
certification  requirements  are more  burdensome  than those  applicable  under
current  Treasury  regulations.  These new  Treasury  regulations  also  provide
special  rules  to  determine   whether,   for  purposes  of   determining   the
applicability of a tax treaty, our distributions to a non-U.S.  shareholder that
is an  entity  should be  treated  as paid to the  entity or to those  owning an
interest in that  entity,  and whether the entity or its owners are  entitled to
benefits under the tax treaty. These new Treasury regulations encourage non-U.S.
shareholders and withholding agents to use the new IRS Forms W-8 series,  rather
than the  predecessor  IRS Forms W-8, 1001, and 4224, and require use of the IRS
Forms W-8 series for payments made after December 31, 2000.

         If our shares are not "United  States real property  interests"  within
the  meaning  of  Section  897  of  the  Internal   Revenue   Code,  a  non-U.S.
shareholder's  gain on sale of these  shares  generally  will not be  subject to
United  States  federal  income  taxation,   except  that  a  nonresident  alien
individual  who was present in the United States for 183 days or more during the
taxable  year will be  subject to a 30% tax on this  gain.  Our shares  will not
constitute  a United  States real  property  interest if we are a  "domestically
controlled REIT." A domestically controlled REIT is a REIT in which at all times
during the  preceding  five-year  period less than 50% in value of its shares is
held directly or indirectly by foreign persons.  We believe that we are and will
be a domestically controlled REIT and thus a non-U.S. shareholder's gain on sale
of our shares  will not be subject to United  States  federal  income  taxation.
However,  because our shares are  publicly  traded,  we can provide no assurance
that we will be a  domestically  controlled  REIT. If we are not a  domestically
controlled REIT, a non-U.S. shareholder's gain on sale of our shares will not be
subject to United States  federal  income  taxation as a sale of a United States
real  property  interest,  if that  class of shares is  "regularly  traded,"  as
defined by applicable Treasury regulations,  on an established securities market
like the New York Stock Exchange, and the non-U.S.  shareholder has at all times
during  the  preceding  five  years  owned 5% or less by value of that  class of
shares.  If the gain on the sale of our shares  were  subject  to United  States
federal income taxation,  the non-U.S.  shareholder will generally be subject to
the same  treatment  as a U.S.  shareholder  with  respect to its gain,  will be
required to file a United States federal income tax return  reporting that gain,
and in the case of corporate non-U.S.  shareholders might owe branch profits tax
under Section 884 of the Internal Revenue Code. A purchaser of our shares from a
non-U.S.  shareholder  will not be required to withhold on the purchase price if
the purchased shares are regularly traded on an established securities market or
if we are a domestically  controlled REIT. Otherwise,  a purchaser of our shares
from a non-U.S.  shareholder  may be required to  withhold  10% of the  purchase
price paid to the non-U.S.  shareholder  and to remit the withheld amount to the
IRS.

Backup Withholding and Information Reporting

         Information reporting and backup withholding may apply to distributions
or proceeds paid to our shareholders  under the  circumstances  discussed below.
Amounts  withheld under backup  withholding  are

                                       25
<PAGE>

generally not an additional tax and may be refunded or credited against the REIT
shareholder's federal income tax liability.

         A U.S.  shareholder will be subject to backup withholding at a 31% rate
when it  receives  distributions  on our  shares  or  proceeds  upon  the  sale,
exchange, redemption,  retirement or other disposition of our shares, unless the
U.S. shareholder properly executes under penalties of perjury an IRS Form W-9 or
substantially similar form that:

     o    provides  the  U.S.  shareholder's  correct  taxpayer   identification
          number; and

     o    certifies that the U.S.  shareholder is exempt from backup withholding
          because it is a corporation or comes within  another exempt  category,
          it has not been  notified  by the IRS  that it is  subject  to  backup
          withholding,  or it has been  notified by the IRS that it is no longer
          subject to backup withholding.

If the U.S.  shareholder  does not provide its correct  taxpayer  identification
number on the IRS Form W-9 or  substantially  similar form, it may be subject to
penalties imposed by the IRS and the REIT or other applicable  withholding agent
may also have to withhold a portion of any capital  gain  distributions  paid to
it. Unless the U.S.  shareholder has established on a properly executed IRS Form
W-9 or  substantially  similar  form that it is a  corporation  or comes  within
another  exempt  category,  distributions  on our  shares  paid to it during the
calendar year, and the amount of tax withheld if any, will be reported to it and
to the IRS.

         Distributions  on our  shares to a  non-U.S.  shareholder  during  each
calendar year and the amount of tax withheld, if any, will generally be reported
to  the  non-U.S.  shareholder  and  to  the  IRS.  This  information  reporting
requirement applies regardless of whether the non-U.S. shareholder is subject to
withholding  on  distributions  on our shares or  whether  the  withholding  was
reduced or eliminated by an applicable tax treaty. Also, distributions paid to a
non-U.S. shareholder on our shares may be subject to backup withholding at a 31%
rate,  unless  the  non-U.S.   shareholder   properly   certifies  its  non-U.S.
shareholder  status  on an IRS Form  W-8 or  substantially  similar  form in the
manner  described  above.  Similarly,   information  reporting  and  31%  backup
withholding will not apply to proceeds a non-U.S.  shareholder receives upon the
sale,  exchange,  redemption,  retirement or other disposition of our shares, if
the non-U.S.  shareholder properly certifies its non-U.S.  shareholder status on
an IRS Form W-8 or  substantially  similar form. Even without having executed an
IRS Form W-8 or substantially  similar form,  however, in some cases information
reporting and 31% backup  withholding will not apply to proceeds that a non-U.S.
shareholder  receives upon the sale, exchange,  redemption,  retirement or other
disposition  of our shares if the non-U.S.  shareholder  receives those proceeds
through a broker's foreign office. As described above, new Treasury  regulations
alter the  information  reporting  and backup  withholding  rules  applicable to
non-U.S.  shareholders for payments made after December 31, 2000, and in general
these new Treasury  Regulations  replace IRS Forms W-8,  1001, and 4224 with the
new IRS Forms W-8 series.  For a non-U.S.  shareholder  whose income and gain on
our shares is  effectively  connected to the conduct of a United States trade or
business,  a slightly  different  rule may apply to proceeds  received  upon the
sale, exchange, redemption, retirement or other disposition of our shares. Until
the non-U.S. shareholder complies with the new Treasury regulations, information
reporting and 31% backup  withholding  may apply in the same manner as to a U.S.
shareholder,  and thus the non-U.S.  shareholder may have to execute an IRS Form
W-9 or substantially similar form to prevent the backup withholding.

Other Tax Consequences

         You should recognize that our and our shareholders'  federal income tax
treatment may be modified by legislative, judicial, or administrative actions at
any time,  which actions may be  retroactive  in effect.  The rules dealing with
federal income taxation are constantly under review by the Congress, the IRS and
the Treasury  Department,  and statutory  changes as well as promulgation of new
regulations,  revisions to existing regulations,  and revised interpretations of
established  concepts  occur  frequently.  No  prediction  can be made as to the
likelihood of passage of new tax legislation or other provisions either directly
or indirectly affecting us and our

                                       26
<PAGE>

shareholders.  Revisions in federal income tax laws and interpretations of these
laws could adversely affect the tax consequences of an investment in our shares.
We and our  shareholders  may also be  subject  to state  or local  taxation  in
various  state  or  local  jurisdictions,  including  those  in  which we or our
shareholders  transact business or reside.  State and local tax consequences may
not be comparable to the federal income tax consequences discussed above.

           ERISA PLANS, KEOGH PLANS AND INDIVIDUAL RETIREMENT ACCOUNTS

General Fiduciary Obligations

         Fiduciaries of a pension, profit-sharing or other employee benefit plan
subject  to Title I of the  Employee  Retirement  Income  Security  Act of 1974,
ERISA, must consider whether:

     o    their   investment  in  our  shares   satisfies  the   diversification
          requirements of ERISA;

     o    the  investment  is prudent in light of  possible  limitations  on the
          marketability of our shares;

     o    they have  authority  to  acquire  our  shares  under  the  applicable
          governing instrument and Title I of ERISA; and

     o    the   investment  is  otherwise   consistent   with  their   fiduciary
          responsibilities.

         Trustees  and other  fiduciaries  of an ERISA  plan may incur  personal
liability  for any loss  suffered by the plan on account of a violation of their
fiduciary  responsibilities.  In addition, these fiduciaries may be subject to a
civil  penalty of up to 20% of any amount  recovered by the plan on account of a
violation.  Fiduciaries  of any IRA,  Roth IRA,  Keogh  Plan or other  qualified
retirement  plan not  subject  to Title I of ERISA,  referred  to as  "non-ERISA
plans,"  should  consider  that  a plan  may  only  make  investments  that  are
authorized  by the  appropriate  governing  instrument.  Fiduciary  shareholders
should  consult their own legal  advisors if they have any concern as to whether
the investment is consistent with the foregoing criteria.

Prohibited Transactions

         Fiduciaries of ERISA plans and persons  making the investment  decision
for an IRA or other  non-ERISA  plan  should  consider  the  application  of the
prohibited  transaction  provisions  of ERISA and the  Internal  Revenue Code in
making their investment decision.  Sales and other transactions between an ERISA
plan or a non-ERISA plan, and persons related to it are prohibited transactions.
The  particular  facts   concerning  the   sponsorship,   operations  and  other
investments  of an ERISA plan or non-ERISA  plan may cause a wide range of other
persons to be  treated as  disqualified  persons  or  parties in  interest  with
respect to it. A  prohibited  transaction,  in addition  to  imposing  potential
personal  liability  upon  fiduciaries  of ERISA  plans,  may also result in the
imposition  of an excise tax under the Internal  Revenue Code or a penalty under
ERISA upon the  disqualified  person or party in  interest  with  respect to the
plan.  If  the  disqualified  person  who  engages  in  the  transaction  is the
individual  on  behalf  of  whom  an  IRA  or  Roth  IRA  is  maintained  or his
beneficiary,  the IRA or Roth IRA may lose its tax-exempt  status and its assets
may  be  deemed  to  have  been  distributed  to  the  individual  in a  taxable
distribution on account of the prohibited transaction, but no excise tax will be
imposed.  Fiduciary  shareholders  should consult their own legal advisors as to
whether the ownership of our shares involves a prohibited transaction.

Special Fiduciary and Prohibited Transactions Consequences

         The Department of Labor, which has administrative  responsibility  over
ERISA plans as well as non-ERISA plans,  has issued a regulation  defining "plan
assets." The regulation  generally provides that when an ERISA or non-ERISA plan
acquires a security that is an equity interest in an entity and that security is
neither a "publicly  offered  security"  nor a security  issued by an investment
company registered under the Investment Company Act of 1940, the ERISA plan's or
non-ERISA  plan's  assets  include  both the equity  interest  and an  undivided
interest  in  each  of  the  underlying  assets  of  the  entity,  unless  it is
established  either  that the  entity is an  operating  company  or that  equity
participation in the entity by benefit plan investors is not significant.

         Each  class of our shares  that is, our common  shares and any class of
preferred  shares that we may issue must be  analyzed  separately  to  ascertain
whether it is a publicly  offered  security.  The regulation  defines a

                                       28
<PAGE>

publicly  offered  security  as  a  security  that  is  "widely  held,"  "freely
transferable"  and either  part of a class of  securities  registered  under the
Securities  Exchange  Act of  1934,  or sold  under  an  effective  registration
statement  under  the  Securities  Act of  1933,  provided  the  securities  are
registered  under the Securities  Exchange Act of 1934 within 120 days after the
end of the fiscal year of the issuer during which the offering occurred. All our
outstanding  shares have been  registered  under the Securities  Exchange Act of
1934.

         The regulation  provides that a security is "widely held" only if it is
part of a class of securities that is owned by 100 or more investors independent
of the  issuer  and of one  another.  However,  a  security  will not fail to be
"widely  held"  because  the number of  independent  investors  falls  below 100
subsequent  to the  initial  public  offering  as a result of events  beyond the
issuer's  control.  Our common  shares  have been  widely held and we expect our
common  shares to continue to be widely  held.  We expect the same to be true of
any class of preferred stock that we may issue,  but we can give no assurance in
that regard.

         The   regulation   provides   that   whether  a  security   is  "freely
transferable"  is a  factual  question  to be  determined  on the  basis  of all
relevant facts and circumstances.  The regulation further provides that, where a
security is part of an offering  in which the minimum  investment  is $10,000 or
less,  some   restrictions  on  transfer   ordinarily  will  not,  alone  or  in
combination, affect a finding that these securities are freely transferable. The
restrictions  on transfer  enumerated in the  regulation  as not affecting  that
finding include:

     o    any  restriction on or prohibition  against any transfer or assignment
          which would result in a termination or reclassification for federal or
          state tax purposes,  or would  otherwise  violate any state or federal
          law or court order;

     o    any  requirement  that advance  notice of a transfer or  assignment be
          given to the issuer and any requirement  that either the transferor or
          transferee,    or   both,   execute    documentation   setting   forth
          representations  as to compliance  with any  restrictions  on transfer
          which are among those  enumerated  in the  regulation as not affecting
          free  transferability,  including  those  described  in the  preceding
          clause of this sentence;

     o    any  administrative  procedure which establishes an effective date, or
          an  event  prior  to  which  a  transfer  or  assignment  will  not be
          effective; and

     o    any limitation or  restriction on transfer or assignment  which is not
          imposed by the issuer or a person acting on behalf of the issuer.

         We believe that the restrictions imposed under our declaration of trust
on the  transfer  of shares do not  result in the  failure  of our  shares to be
"freely  transferable."  Furthermore,  we believe that at present there exist no
other facts or circumstances  limiting the  transferability  of our shares which
are  not  included   among  those   enumerated  as  not  affecting   their  free
transferability  under the regulation,  and we do not expect or intend to impose
in the future, or to permit any person to impose on our behalf,  any limitations
or restrictions on transfer which would not be among the enumerated  permissible
limitations or restrictions.

         Assuming  that each class of our shares will be "widely  held" and that
no other facts and circumstances  exist which restrict  transferability of these
shares, we have received an opinion of our counsel Sullivan & Worcester LLP that
our  shares  will not  fail to be  "freely  transferable"  for  purposes  of the
regulation  due  to  the  restrictions  on  transfer  of the  shares  under  our
declaration  of trust and that under the  regulation  the  shares  are  publicly
offered  securities and our assets will not be deemed to be "plan assets" of any
ERISA plan or non-ERISA plan that invests in our shares.

Item 2.  Properties

         At December 31, 1999, we had real estate  investments  totaling  $731.7
million,  at cost, after an impairment loss write-down and loan loss reserve, in
93 properties that were leased to or operated by nine tenants or mortgagors.  We
believe that the physical  plant of the  facilities in which we have invested is
suitable and adequate  for our present and any  proposed  uses.  At December 31,
1999, 18 properties  with an aggregate  cost of $427.4 million were mortgaged to
secure our bank credit facility.

         The following table summarizes some information about our properties as
of December 31, 1999.  All dollar  figures are in  thousands.  Certain  tenants'
obligations  to pay the  rents or  interest  stated  below  may be  affected  by
bankruptcy proceedings affecting those tenants. See "Item 1.  Business--Business
Developments--Tenant Financial Condition."

Item 3.  Legal Proceedings

         Although  in the  ordinary  course  of  business  we are or may  become
involved in legal  proceedings,  we have a limited operating history and are not
aware of any material pending legal proceedings  affecting any of our properties
for  which we might  become  liable.  However,  as  discussed  above in "Item 1.
Business--Business  Developments--Tenant  Financial  Condition,"  several of our
tenants have filed for bankruptcy,  and we are pursuing claims and  negotiations
in those bankruptcy proceedings. The amounts at stake in these tenant bankruptcy
proceedings are material.

Item 4.  Submission of Matters to a Vote of Security Holders

         No matters were submitted to a vote of  shareholders  during the fourth
quarter of the year covered by this Annual Report on Form 10-K.

Item 5.  Market for Registrant's Common Stock and Related Shareholder Matters

         Our Shares began trading on the New York Stock Exchange  (symbol:  SNH)
on October 12, 1999. The following table sets forth for the period indicated the
high and low  closing  sale  prices for the Shares as  reported  in the New York
Stock Exchange Composite Transactions reports.

                                                       High             Low
                                                       ----             ---
Fourth Quarter 1999 (since October 12, 1999)         $16 5/16         $11 1/16

         The closing price of the Shares on the New York Stock Exchange on March
27, 2000 was $9 7/8.

         As of March 27, 2000, there were approximately  5,229 holders of record
of the  Shares,  and we  estimate  that as of such date  there were in excess of
100,000 beneficial owners of the Shares.

         The following table sets forth the amount of distributions paid in 1999
and the respective annualized rates.

                                  Distribution                 Annualized
                                    Per Share               Distribution Rate
                                    ---------               -----------------
November 22, 1999                     $0.60                       $2.40

         All distributions have been paid and 100% of the 1999 distribution was
classified as ordinary income and there was no return of capital.  As previously
discussed,  two of  our  largest  tenants,  IHS  and  Mariner  have  experienced
significant  operating  losses in 1999.  Earlier  this year they both  filed for
bankruptcy.  These two  tenants are  responsible  for  approximately  48% of our
revenues.  We  have  reached  a  tentative  agreement  with  Mariner,  which  is
contingent  upon third party  approvals  and we continue to  negotiate  with IHS
regarding our future business  relationships.  A smaller tenant, Frontier Group,
Inc., which represents 2% of our revenues filed for bankruptcy  during 1999 and,
in February 2000 we sold these three properties for $13.0 million.  See "Item 1.
Business--Business  Developments--Tenant  Financial  Condition."  The  level  of
distributions to be made by us will depend, in part, on the final outcome of the
negotiations with these tenants.

         In order to qualify for the beneficial tax treatment  accorded to REITs
by Sections 856 through 860 of the  Internal  Revenue  Code,  we are required to
make  distributions  to shareholders  which annually will be at least 95% of our
taxable income.  All  distributions  will be made by us at the discretion of the
Trustees  and  will  depend  on  our  earnings,  our  cash  flow  available  for
distribution,  our financial  condition and other factors that the Trustees deem
relevant. We have in the past distributed, and intend to continue to distribute,
substantially  all of our real estate  investment  trust  taxable  income to our
shareholders.

         In October 1999,  pursuant to our Incentive  Share Award Plan,  our two
independent trustees at the time of our Spin-Off from HRPT each received a grant
of 500 Shares valued at $16.50 per Share, the average price of the Shares on the
NYSE on October 12, 1999 and our third independent trustee, who was subsequently
elected to the fill the  vacancy on our Board of  Trustees,  received a grant of
500 Shares  valued at $12.75 per Share,  the closing  price of the Shares on the
NYSE on October 21, 1999.  The grants were made pursuant to the  exemption  from
registration  contained  in  Section  4(2) of the  Securities  Act of  1933,  as
amended.

Item 6.  Selected Financial Data

         Prior to October 12, 1999,  we and our  properties  were owned by HRPT.
The following  data is presented as if we were a separate  entity from HRPT. Set
forth below is selected financial data for the periods and dates indicated. This
financial data has been derived from HRPT's historical  financial statements for
periods prior to October 12, 1999.  Per share data has been  presented as if the
shares were outstanding for all periods prior to October 12, 1999. The following
table  includes  pro rata  allocations  of  interest  expense  and  general  and
administrative expenses for periods prior to October 12, 1999. In the opinion of
our  management,  the  methods  used for  allocating  interest  and  general and
administrative  expenses are reasonable.  However,  it is impossible to estimate
all  operating  costs that we would have incurred as a separate  public  company
from HRPT.  Accordingly,  the net income and funds from operations shown are not
necessarily  indicative  of results  that we may realize as a separate  company.
Additionally,  year to year  comparisions are impacted by property  acquisitions
during historical periods.  This data should be read in conjunction with, and is
qualified in its entirety by reference to, the consolidated financial statements
and accompanying  notes included herein in Item 14 of this Annual Report on Form

Item 7. Management's  Discussion and Analysis of Financial Condition and Results
        of Operations

         The following information is provided in connection with, and should be
read in conjunction with, the Consolidated  Financial Statements included herein
as Item 14 of this Annual Report on Form 10-K.

RESULTS OF OPERATIONS

Year Ended December 31, 1999, Compared to 1998

         For the year  ended  December  31,  1999,  compared  to the year  ended
December 31, 1998,  total  revenues  increased by $2.5 million,  total  expenses
increased  by $33.9  million and net income  decreased by $31.4  million.  Total
revenues  increased due to the full year impact of the rent  generated from five
properties  acquired during 1998.  Total expenses  increased  primarily due to a
$30.0 million charge to income  consisting of a write-down for the impairment of
assets and a loan loss reserve. In addition,  depreciation  expense increased by
$4.0 million,  due to a change in the estimated useful lives of some real estate
properties and the full year impact of five properties acquired during 1998. Net
income was $14.8 million, or $0.57 per share, for the period ending December 31,
1999.  During the period ending December 31, 1998, net income was $46.2 million,
and on a pro forma 26.0 million average shares  outstanding net income was $1.78
per share.

         As previously announced,  three of our tenants,  Frontier,  Mariner and
IHS have filed for protection under the bankruptcy laws.  Frontier filed in July
1999,  Mariner filed in January 2000 and IHS filed in February 2000.  Bankruptcy
laws may allow  our  tenants  relief or  discharge  them  from  their  financial
obligations  to us. For 1999,  rental and mortgage  interest  income  related to
Frontier,  Mariner and IHS was $2.2 million,  $15.4  million and $26.6  million,
respectively.  At December 31, 1999 real estate  investments,  before impairment
loss  recognition and net of accumulated  depreciation,  for these three tenants
were $10.0 million, $68.3 million and $136.9 million,  respectively. We also had
mortgage investments,  before loss reserves,  related to IHS of $36.6 million at
December  31,  1999.  Based on  estimates  of future cash flows from  properties
leased to Mariner and IHS, we recognized an impairment in the carrying  value of
properties totaling $30.0 million.

         In February 2000,  all of the  properties  that were leased to Frontier
were sold for $13.0 million.  In March 2000, we repaid $12.0 million on our bank
credit facility.

         In March  2000,  we reached a  conditional  agreement  with  Mariner as
follows:

     o    Mariner's  lease  obligations  for all 26 properties  which we own and
          lease to Mariner will be terminated.

     o    Approximately  $24.0 million of cash and  securities  which we hold to
          secure Mariner's obligations will be retained by us.

     o    We  will  assume  operating   responsibilities  for  17  of  these  26
          properties.  Title to five of these  properties will be transferred to
          Mariner which will continue the operations. The remaining four nursing
          homes are now  subleased  to two  private  companies  and we expect to
          negotiate with these two subtenants for their continued  operations of
          those properties.

Item 7. Management's  Discussion and Analysis of Financial Condition and Results
        of Operations - continued

Our agreement  with Mariner is contingent  upon approval by Mariner's  creditors
committee and the Delaware Bankruptcy Court before which Mariner's bankruptcy is
pending and required  regulatory  approvals  from various  states where affected
nursing homes are located.

         The three Frontier properties which have been sold and the five Mariner
properties which may be transferred for retention of the security deposits which
we hold have been  owned by us and our  predecessor,  HRPT  since 1987 and 1990,
respectively.  Because of previously recorded  depreciation and other accounting
requirements we expect to realize  accounting and tax gains as a result of these
transactions  during the first half of 2000. At the same time,  future  interest
savings from the  repayment of our bank credit  facility  with the proceeds from
the sale of the  Frontier  properties  and  operating  earnings  from the former
Mariner  properties  is  expected  to be less than the rent which we  previously
received from Mariner and Frontier, at least until the operations of the Mariner
properties  which are assumed by us are stabilized and those properties are sold
or  re-leased.  Because  we are still  pursuing  claims  for breach of lease and
rental  arrearages  for the former  Frontier  properties and because the Mariner
agreement is contingent and subject to possible changes,  the amount of gains or
reduced cash flow which we will realize  cannot be accurately  estimated at this
time.

         We are  currently in  negotiations  with IHS. The current  negotiations
include,  but are not  limited  to,  the  possibilities  that we will  sell  the
properties now leased to IHS, that lease terms may be changed,  that new tenants
may begin operations of these properties,  that properties may be operated by us
for our own account or mortgage  obligations due to us may be released for other
compensation.  No  assurances  can  be  made  as  to  if,  when  and  how  these
negotiations will be concluded. We may recognize additional gains or losses when
these negotiations are completed.

         Funds from  operations for the year ended December 31, 1999, were $67.1
million,  or $2.58 per share,  compared to $64.5 million, or $2.48 per share, in
1998. The increase is due to the full year impact of income from five properties
acquired during 1998.  Non-recurring  and non-cash losses excluded from the 1999
calculation of funds from operations aggregated $30.0 million. Distributions for
the year ended  December 31, 1999,  were $15.6 million or $0.60 per share.  Cash
flow provided by operating  activities and cash available for  distribution  may
not  necessarily  equal funds from  operations as cash flow is affected by other
factors not included in the funds from operations  calculation,  such as changes
in assets and liabilities.

Year Ended December 31, 1998, Compared to 1997

         For the year  ended  December  31,  1998,  compared  to the year  ended
December 31, 1997,  total  revenues  increased by $4.1 million,  total  expenses
increased  by $2.6  million  and net income  increased  by $1.5  million.  Total
revenues increased due to rent generated from the acquisition of five properties
during 1998 and the full year impact of the rent generated from five  properties
acquired  during 1997.  Total  expenses  increased  primarily  because of higher
allocated  interest  expense of $2.3  million,  which  resulted  from  increased
borrowings.  Net income was $46.2  million and $44.7  million for the year ended
December  31,  1998 and 1997,  respectively.  There  were no shares  outstanding
during these periods.  On a pro forma 26.0 million  average shares  outstanding,
net income per share would have been $1.78 and $1.72 for the year ended December
31, 1998 and 1997, respectively.

         Funds from  operations  increased  by $2.0  million  for the year ended
December  31,  1998,  compared  to the  prior  period  due to  income  from five
properties  acquired  during  1998 and the full year  impact of income from five
properties acquired during 1997.

Item 7. Management's  Discussion and Analysis of Financial Condition and Results
        of Operations - continued

LIQUIDITY AND CAPITAL RESOURCES

         In September 1999, our registration statement on Form S-11, relating to
the  distribution  of 13.2 million of our common  shares to HRPT's  shareholders
(the  "Spin-Off")  was  declared   effective  by  the  Securities  and  Exchange
Commission.   Prior  to  the  Spin-Off,   we  had  26.0  million  common  shares
outstanding,  all of which  were  owned by  HRPT.  On  October  12,  1999,  HRPT
distributed  13.2 million of our common shares to HRPT's  shareholders of record
on October 8, 1999.

         At  December  31,  1999,  we had  cash and  cash  equivalents  of $17.1
million.  For the years  ended  December  31,  1999 and 1998,  cash  flows  from
operating  activities were $64.1 million and $60.2 million,  respectively,  cash
flows from investing  activities were $387,000 and $306,000,  respectively,  and
cash  used for  financing  activities  was  $47.5  million  and  $60.4  million,
respectively.  We expect that our current cash,  cash  equivalents,  future cash
flows from  operating  and financing  activities  will be sufficient to meet our
short-term and long-term working capital requirements.

         Total  assets  decreased  by $32.3  million  from $686.3  million as of
December 31, 1998, to $654.0  million as of December 31, 1999.  The decrease was
primarily due to the write-down resulting from impairment of assets, a loan loss
reserve provision and depreciation.

         On  September  1,  1999,  we  agreed  to pay  HRPT  $200  million  (the
"Formation Debt") in connection with the transfer to us of HRPT's 100% ownership
in one of the subsidiaries  that own some of our properties.  The Formation Debt
bore interest at HRPT's weighted average cost of debt,  (7.1%),  and was paid to
HRPT on October 13, 1999.

         In September  1999,  we entered into an agreement  for a $350  million,
three-year,  interest only bank credit facility secured by first mortgages on 18
properties.  The interest rate is LIBOR plus 2.0% per annum and will increase by
0.25% if our debt to total  capital,  as defined,  exceeds  50%. The bank credit
facility is available for acquisitions, working capital and for general business
purposes. We have the ability to repay and redraw amounts under this bank credit
facility until its maturity in 2002. Our bank credit facility  documentation has
customary   representations,   warranties,   covenants   and  event  of  default
provisions. The material restrictive financial covenants require us to:

     o    limit debt to no more than 60% of total capital, as defined;

     o    maintain a ratio of net income plus interest  expense and depreciation
          to interest expense of at least 1.5; and

     o    maintain a tangible net worth, as defined, of $450 million, subject to
          increases based on equity issuances.

         After the  Spin-Off,  we borrowed  $200 million  under this bank credit
facility  which we used to pay the Formation Debt to HRPT. At December 31, 1999,
we had $150 million available under the bank credit facility.  In March 2000, we
used  $12  million  of  proceeds  from  the sale of the  three  former  Frontier
properties to reduce amounts  outstanding under the bank credit facility to $188
million, leaving $162 million available to be borrowed.

         In the  short-term,  we expect to use the bank credit  facility to fund
our working capital needs for operations of the Mariner properties which we will
assume if the Mariner agreement described above is approved.

<PAGE>

Item 7. Management's  Discussion and Analysis of Financial Condition and Results
        of Operations - continued

         In both  the  short-term  and  the  long-term,  we  intend  to  acquire
additional senior housing  properties.  These purchases will be initially funded
with excess working  capital,  if any, and proceeds of borrowings under the bank
credit facility. We expect to repay bank credit facility borrowings periodically
with long-term debt or equity  capital.  We believe that we will have sufficient
access  to  capital  markets  to meet our  working  capital  needs,  our  growth
objectives  and  refinance our debt as needed.  However,  access to capital will
depend upon numerous factors,  including some beyond our control. We can provide
no  assurance  that we will be able to raise  additional  capital in  sufficient
amounts,  or at appropriate  costs,  to meet our working  capital needs, to fund
growth or to repay debt in both the short-term and the long-term.

Impact of Inflation

         Inflation  might  have  both  positive  and  negative  impact  upon our
business.  Inflation  might  cause the value of our real estate  investments  to
increase.  Similarly, in an inflationary environment, the percentage rents which
we receive based upon CPI increases or as a percentage of our tenants'  revenues
should  increase.  Also, rent yields we could charge for new  investments  would
likely increase.  Offsetting these benefits,  inflation might cause the costs of
equity and debt capital to increase. To mitigate the adverse impact of increased
costs  of debt  capital  in the  event of  material  inflation  we may  purchase
interest rate cap agreements.  The decision to enter into these  agreements will
be based on the amount of  floating  rate debt  outstanding  and our belief that
material  interest  rate  increases  are  likely  to  occur.  We do not  believe
inflation in the U.S.  economy  during the next few years will have any material
effect on our business.

Year 2000

         We experienced no disruptions in our  information  and  non-information
technology  systems and incurred no costs with  respect to year 2000 issues.  We
are not aware of any material  problems  resulting  from year 2000 issues by our
systems or the systems of our tenants or their material vendors and our material
vendors,  but will  continue to monitor  these  systems  throughout  the year to
ensure that any late year 2000 issues that may arise are addressed promptly.

Certain Considerations

         The discussion  and analysis of our financial  condition and results of
operations requires us to make estimates and assumptions and contains statements
of our beliefs,  intent or expectation  concerning  projections,  plans,  future
events and performance. The estimates, assumptions and statements, such as those
relating to the  approval of the Mariner  agreement,  our ability to operate and
stabilize  operations  at the Mariner  properties,  our ability to  successfully
negotiate with Mariner's subtenants,  our ability to successfully negotiate with
IHS, our ability to expand our portfolio, performance of our assets, the ability
to make  distributions,  our tax status as a "real estate investment trust," the
ability  to  appropriately  balance  the use of debt and  equity  and to  access
capital  markets,  depend upon various  factors over which we and/or our lessees
have  or  may  have  limited  or no  control.  Those  factors  include,  without
limitation,  the status of the economy, status of the capital markets (including
prevailing  interest rates),  compliance with the changes to regulations  within
the  healthcare  industry,  competition,  changes to federal,  state,  and local
legislation and other factors. We cannot predict the impact of these factors, if
any.  However,  these  factors  could cause our actual  results  for  subsequent
periods  to be  different  from  those  stated,  estimated  or  assumed  in this
discussion and analysis of our financial condition and results of operations. We
believe that our estimates and  assumptions  are  reasonable and prudent at this
time.

Item 7A.  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 $200 million at December 31, 1999, is
8.17% per annum.  An immediate  10% change in that  interest  rate or 81.7 basis
points, would increase or decrease our costs by $1.6 million, or $0.06 per share
per year:

                             (dollars in thousands)

                           Interest Rate   Outstanding      Expense
                              Per Year        Debt          Per Year
                           --------------  -----------    -----------
At December 31, 1999          8.17%         $200,000       $ 16,340
10% reduction                 7.35%          200,000         14,700
10% increase                  8.99%          200,000         17,980

         The  foregoing  table  presents a  so-called  "shock"  analysis,  which
assumes that the interest rate change by 10%, or 81.7 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 few months, short-term U.S. dollar based interest rates
have  tended  to rise.  We are  unable to  predict  the  direction  or amount of
interest  rate changes  during the next year.  We purchased an interest rate cap
agreement  on our  current  debt to protect  against  rate  increases  above 8%.
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.

         We currently own real estate mortgages  receivable  inclusive of a loan
loss reserve with a carrying value of $22.9 million. When comparable term market
interest  rates  decline,  the  value  of  these  receivables  increases;   when
comparable  term  market  interest  rates rise,  the value of these  receivables
declines.  Using discounted cash flow analyses at a weighted  average  estimated
per year market rate for December 31, 1999 of 10.75%,  the estimated  fair value
of our mortgages receivable was $23.7 million.

         An immediate  10% change in the market rate of  interest,  or 108 basis
points,  applicable to our real estate mortgages receivable at December 31,1999,
would affect the fair value of those receivables as follows:

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk - continued

         If the market rate changes occurred  gradually over time, the effect of
these changes  would be realized  gradually.  Because our real estate  mortgages
receivable  are fixed rate  instruments,  changes in market  interest rates will
have no effect on our operating  results unless these  receivables  are sold. At
this time, we expect to hold our existing mortgages to their maturity and not to
realize  any  profit or loss  from  trading  these  mortgages.  Also,  we do not
presently expect to expand our mortgage investments.

         The interest  rate changes that affect the  valuations of our mortgages
are U.S.  dollar  long-term  rates for corporate  obligations  of companies with
ratings similar to our mortgagors.

Item 8.  Financial Statements and Supplementary Data

         The information  required by this item is included herein in Item 14 of

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS





To the Trustees and Shareholders of Senior Housing Properties Trust

We have audited the accompanying  consolidated  balance sheets of Senior Housing
Properties Trust as of December 31, 1999 and 1998, and the related  consolidated
statements of income,  shareholders' equity and cash flows for each of the three
years in the period  ended  December  31,  1999.  Our audits also  included  the
financial  statements  and  schedules  listed in the Index at Item 14(a).  These
financial  statements  and  schedules  are the  responsibility  of the Company's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the financial position of Senior Housing Properties Trust
and  subsidiaries  as of  December  31,  1999 and 1998 and the  results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 1999, in conformity with accounting  principles  generally accepted
in the United  States.  Also, in our opinion,  the related  financial  statement
schedules,  when considered in relation to the basic financial  statements taken
as a whole,  present fairly in all material  respects the  information set forth
therein.

                         SENIOR HOUSING PROPERTIES TRUST

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note 1.  Organization

            The consolidated  financial  statements of Senior Housing Properties
Trust include the accounts of 81  properties  and 12 mortgages  receivable  (the
"Properties")  and of Senior Housing  Properties Trust ("Senior Housing Trust").
The Properties and Senior Housing Trust are collectively  referred to as "Senior
Housing".  These  consolidated  financial  statements are presented as if Senior
Housing  was a legal  entity  separate  from  HRPT  Properties  Trust  ("HRPT");
although no such entity existed until October 12, 1999.  Senior Housing operates
in a single segment.

            HRPT organized Senior Housing Trust, a 100% owned subsidiary through
October 11, 1999,  as a Maryland  real estate  investment  trust on December 16,
1998. At the time of its organization,  Senior Housing Trust issued 26.4 million
shares to HRPT for consideration of $263,748.  Subsequently,  0.4 million shares
were cancelled and 26.0 million shares are currently issued and outstanding.

            For a substantial part of the periods presented, the Properties were
owned by HRPT. On or about June 30, 1999,  the  Properties  were  transferred by
HRPT to several of its 100% owned  subsidiaries.  Effective  as of  September 1,
1999, HRPT transferred 100% ownership of the several subsidiaries, which own the
Properties,  to Senior Housing Trust. On October 12, 1999, HRPT distributed 13.2
million  shares  of its  26.0  million  Senior  Housing  Trust  shares  to  HRPT
shareholders (the "Spin-Off").

Note 2.  Summary of Significant Accounting Policies

BASIS OF PRESENTATION. Prior to the Spin-Off, all of Senior Housing was owned by
HRPT, and transactions have been presented at HRPT's historical basis.  Prior to
the Spin-Off  substantially  all the rental income and mortgage  interest income
received by HRPT from the tenants and mortgagors of Senior Housing was deposited
in and commingled with HRPT's general funds.  Funds for capital  investments and
other cash required by Senior  Housing was provided by HRPT.  Prior to September
1, 1999,  interest  expense was allocated  based on HRPT's  historical  interest
expense  as a  percentage  of HRPT's  average  historical  costs of real  estate
investments.  General and administrative  costs of HRPT for the periods prior to
the  Spin-Off  were  allocated  to Senior  Housing  based on  HRPT's  investment
advisory  agreement  formula and other costs were allocated  based on historical
costs  as a  percentage  of  HRPT's  average  historical  costs  of real  estate
investments.  In the opinion of management,  the methods for allocating interest
and general and administrative expenses were reasonable.  It was not practicable
to estimate  additional costs that would have been incurred by Senior Housing as
a separate entity.

REAL ESTATE  PROPERTIES AND MORTGAGE  INVESTMENTS.  Depreciation  on real estate
properties is expensed on a straight-line  basis over estimated  useful lives of
up to 40 years for  buildings and  improvements  and up to 12 years for personal
property.  During  1999,  the  estimated  useful  lives of certain  real  estate
properties  were changed.  The effect reduced net income and earnings per share,
for the period  ending  December  31,  1999,  $3.8  million and $0.15 per share,
respectively.  Impairment losses on properties are recognized when indicators of
impairment  are  present  and  the  estimated,  undiscounted  cash  flows  to be
generated  by the  properties  are less than the  carrying  amount of  concerned
properties.

CASH AND CASH  EQUIVALENTS.  Cash and cash  equivalents  consisting of overnight
repurchase  agreements and short-term  investments  with original  maturities of
three  months or less at the date of purchase  are carried at cost plus  accrued
interest which approximates market.

INTEREST RATE CAP  AGREEMENTS.  Senior Housing has entered into an interest rate
cap  agreement  to limit  exposure to the risk of rising  interest  rates.  This
arrangement,  which  expires in  December  2001,  has a notional  amount of $200
million.  Senior Housing will be entitled to receive  payments by a counterparty
should LIBOR increase above a threshold amount.

REVENUE  RECOGNITION.  Rental  income from  operating  leases is recognized on a
straight-line  basis over the life of the lease  agreements.  Interest income is
recognized  as earned  over the terms of the real estate  mortgages.  Percentage
rent and  supplemental  mortgage  interest income are recognized as earned.  For
interim periods,  percentage rent and supplemental  mortgage interest income are
accrued prior to  achievement of specified  targets when the  achievement of the
targets is  probable.  For the years ended  December  31,  1999,  1998 and 1997,
percentage  rent and  supplemental  mortgage  interest  income  aggregated  $4.0
million, $2.9 million and $2.9 million, respectively.

EARNINGS PER COMMON SHARE.  Because Senior Housing's operations were included in
the consolidated  financial statements of HRPT prior to the Spin-Off,  there are
no shareholder  equity accounts for Senior Housing prior to 1999.  Common shares
outstanding  of 26.0  million  at October  12,  1999 have been  included  in the
earnings per share calculation as if the shares were outstanding for all periods
prior to October 12, 1999.  Earnings  per common  share are  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.

USE OF ESTIMATES.  Preparation of these financial  statements in conformity with
generally accepted  accounting  principles requires management to make estimates
and  assumptions  that may  affect  the  amounts  reported  in  these  financial
statements  and  related  notes.  The actual  results  could  differ  from these
estimates.

INCOME TAXES. Prior to the Spin-Off,  Senior Housing's  operations were included
in HRPT's  income tax  returns.  Senior  Housing and HRPT qualify as real estate
investment  trusts  under  the  Internal  Revenue  Code  of  1986,  as  amended.
Accordingly,  they are not  expected  to be  subject  to  federal  income  taxes
provided they  distribute  their  taxable  income and continue to meet the other
requirements for qualifying as a real estate investment trust. However, they are
subject to state and local taxes on their income and property.

NEW ACCOUNTING  PRONOUNCEMENTS.  The Financial Accounting Standards Board issued
Statement No. 133 "Accounting for Derivative Instruments and Hedging Activities"
("FAS 133") in 1998,  which was further amended by Statement No. 137 "Accounting
for Derivative  Instruments and Hedging Activities - Deferral of Effective Date
of FASB  Statement  No.  133" in  1999.  FAS 133  must be  adopted  for the 2001
financial  statements.  Senior  Housing  believes  adoption  of  FAS  133 is not
expected to have a  significant  impact on its reported  financial  condition or
results of operations.

Note 3.  Report of Tenants' Financial Condition

         Three  of  Senior   Housing's   tenants,   The  Frontier  Group,   Inc.
("Frontier"), Mariner Post-Acute Network, Inc. ("Mariner") and Integrated Health
Services, Inc. ("IHS") have filed for protection under bankruptcy laws. Frontier
filed in July  1999,  Mariner  filed in January  2000 and IHS filed in  February
2000. For 1999, rental income and mortgage interest related to Frontier, Mariner
and IHS was $2.2 million,  $15.4  million and $26.6  million,  respectively.  At
December 31, 1999 real estate  investments,  before  impairment loss recognition
and net of accumulated depreciation, for these three tenants were $10.0 million,
$68.3 million and $136.9 million, respectively. Senior Housing also had mortgage
investments,  before loss reserves,  related to IHS of $36.6 million at December
31, 1999.

         Senior  Housing has concluded  that  impairment  indicators are present
with  respect  to  properties   operated  by  these  tenants  and  has  prepared
undiscounted  cash flow projections for each of the properties.  For purposes of
these projections,  Senior Housing has assumed that rents on some properties may
be modified  and that some of the leases may be  terminated  after which  Senior
Housing will operate the properties for a period of time and,  ultimately,  sell
them. In addition,  a third party not in  bankruptcy  has  guaranteed  the lease
obligations  of some of the  properties  operated by one of the tenants.  Senior
Housing has assumed that the  guarantor  will honor the lease  obligations.  The
undiscounted cash flow projections  reflect the expected rents to be earned over
the lease term and the expected cash flows earned from  operating the properties
for a  period  of time  plus  the  proceeds

                                      F-7

                         SENIOR HOUSING PROPERTIES TRUST

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

from  assumed  future sales of the  properties.  Cash flows during the period in
which  Senior  Housing may operate the  properties  are  estimated  based on the
historical performance of each property,  excluding rent paid to Senior Housing.
Projected  sale prices are based on an estimated per bed value  consistent  with
industry  practice and reflect prices that Senior Housing has observed in recent
transactions.  Based on these undiscounted cash flow projections, Senior Housing
has  concluded  that  certain of its real estate and  mortgage  investments  are
impaired as of December 31, 1999.  Based on its  estimates of fair values net of
selling costs,  Senior Housing has written down the carrying value of these real
estate  investments,  including  investments  leased to an  affiliate,  Advisors
Healthcare Group, Inc. ("Advisors Health"), as of December 31, 1999 by recording
an impairment  loss  write-down in the  accompanying  consolidated  statement of
income of $15.5  million.  In addition,  Senior Housing has recorded a loan loss
reserve  of $14.5  million  related to the  mortgage  investment  it  considered
impaired. It is reasonably possible that estimates of future cash flows could be
reduced significantly  depending on the outcome of the bankruptcy proceedings or
if the third party should fail to honor its guarantee.  As a result,  additional
losses could be recognized in future periods and the amounts could be material.

         In February 2000,  Senior Housing sold all of the properties  that were
leased to Frontier for $13.0  million.  Senior  Housing is  continuing to pursue
claims  against  Frontier  and other  parties  for  breach of its leases and for
rental  arrearages.  The amount of net gain, if any,  which may be realized from
the sale of the  Frontier  properties  will  depend  upon the  outcome  of these
claims.  The  amount  of  gain  or  loss  to be  realized  as a  result  of this
transaction is not expected to be material.  Because these  properties have been
sold, Senior Housing will no longer receive rental income from these properties.

         In March 2000,  Senior  Housing  reached an agreement in principle with
Mariner  whereby  Mariner may be released  from its lease  obligations,  certain
security  deposits  held by Senior  Housing may be  retained by Senior  Housing,
certain  properties  now  operated by Mariner  will in the future be operated by
Senior  Housing,  and  other  properties  now owned by  Senior  Housing  will be
conveyed to Mariner.  If this agreement is approved  Senior Housing expects that
it may  realize  gains and that its future  earnings  and cash flows may be less
than the rent  previously  earned from the Mariner  leases,  at least on a short
term basis.  This  agreement is  contingent  upon third party  approvals  beyond
Senior  Housing's  control.  If and when this  agreement is  implemented  it may
result in additional material gains or losses.

         Senior  Housing is  currently  in  negotiations  with IHS.  The current
negotiations  include,  but are not  limited to, the  possibilities  that Senior
Housing will sell some of the  properties,  that lease or mortgage  terms may be
changed,  that new tenants may begin  operations of properties,  that properties
may be  operated  by  Senior  Housing  for its  own  account  or  that  mortgage
obligations due to Senior Housing may be released for other compensation. Senior
Housing may recognize  additional  gains or losses when these  negotiations  are
completed and the additional gains or losses may be material.

Note 4.  Real Estate Properties

         The  owned  Properties  are  generally  leased on a triple  net  basis,
pursuant to noncancellable, fixed term operating leases expiring between 2001 to
2019.  Generally,  the leases to a single tenant or group of affiliated  tenants
are  cross-defaulted  and  cross-guaranteed,  and provide for all or none tenant
renewal options at existing rates followed by several market rate renewal terms.
These  triple  net  leases  generally  require  the  lessee to pay all  property
operating costs.

         The future  minimum  lease  payments to be received  during the current
terms of the leases, as of December 31, 1999, were  approximately  $78.3 million
in 2000,  $78.0 million in 2001,  $79.4 million in 2002,  $79.6 million in 2003,
$79.4  million in 2004 and $602.7  million  thereafter.  These  future  payments
include  minimum  lease  payments from IHS and Mariner of $36.3 million in 2000,
$36.5  million in 2001,  $36.6  million in 2002,  $36.8  million in 2003,  $36.9
million in 2004, and $179.9 million thereafter.

           At December 31, 1999,  the interest  rates on these notes  receivable
ranged from 10.3% to 13.75% per annum.  In 1999 Senior  Housing  established  an
allowance of $14.5  million for the  impairment  of a real estate  mortgage loan
with a face value of $18.8 million.

Note 6.  Shareholders' Equity

           Senior  Housing has  reserved  1,300,000  shares of Senior  Housing's
common shares under the terms of the 1999 Incentive Share Award Plan (the "Award
Plan").  During 1999, the three  Independent  Trustees,  as part of their annual
fee, were each granted 500 common shares from this plan.  The shares  granted to
the  Trustees  vest  immediately.  At December  31,  1999,  1,298,500  of Senior
Housing's common shares remain reserved for issuance under the Award Plan.

           In January 2000,  Senior Housing declared a distribution of $0.60 per
share which was distributed on February 24, 2000.  Distributions  per share paid
by Senior Housing for 1999 were $0.60 per share, or approximately $15.6 million.

Note 7.  Commitments and Contingencies

          At December 31, 1999 and 1998,  Senior  Housing had total  commitments
aggregating $3.7 million to fund or finance improvements to the Properties.

Note 8.  Transactions with Affiliates

          Senior  Housing has entered into an agreement  with REIT  Management &
Research,  Inc.  ("REIT  Management")  to provide  investment,  management  and
administrative  services.  Gerard M. Martin and Barry M.  Portnoy,  who serve as
managing  trustees  of  Senior  Housing  and  HRPT,  own REIT  Management.  REIT
Management is paid by Senior Housing based on a formula amount of gross invested
assets in the properties.  Investment advisory fees for 1999, 1998 and 1997 with
respect to Senior Housing's invested assets were $3.9 million,  $3.8 million and
$3.7 million,  respectively.  Beginning with the year ending  December 31, 2000,
REIT  Management  will also be entitled to an incentive  fee, paid in restricted
shares, based on a formula.

          Messrs.  Martin and Portnoy  are  principal  shareholders  of Advisors
Health  (formerly  known as  Connecticut  Subacute  Corporation  II), which is a
lessee of Senior  Housing.  The lease  with  Advisors  Health is based on market
terms and is  generally  similar to Senior  Housing's  leases with  unaffiliated
companies.  These  properties are managed by IHS. Senior Housing recorded rental
income of $4.5 million as a result of this lease during each of the years ending
December 31, 1999, 1998 and 1997.

Note 9.  Indebtedness

          In September 1999, Senior Housing entered into an agreement for a $350
million,  three-year,  interest  only,  bank  credit  facility.  The bank credit
facility is secured by 18 properties, with a net book value of $380.2 million at
December  31,  1999,  and  matures in 2002.  The  interest  rate is LIBOR plus a
premium (8.17% at December 31, 1999) and will increase if Senior  Housing's debt
to total capital, as defined,  meets or exceeds 50%. The bank credit facility is
available for acquisitions,  working capital and for general business  purposes.
On October 13, 1999,  $200 million,  used to pay the formation debt due to HRPT,
was outstanding under the bank credit facility.

                         SENIOR HOUSING PROPERTIES TRUST


                      ARTICLES OF AMENDMENT AND RESTATEMENT


         FIRST:   Senior  Housing  Properties  Trust,  a  Maryland  real  estate
investment  trust (the  "Trust")  formed under Title 8 of the  Corporations  and
Associations Article of the Annotated Code of Maryland (as amended and in effect
from time to time,  and  including  any  successor  title  thereto,  "Title 8"),
desires to amend and restate its Declaration of Trust as currently in effect and
as hereinafter  amended.  All references in the Declaration of Trust to specific
sections of Title 8 shall include applicable successor provisions.

         SECOND:  The  following  provisions  are  all  the  provisions  of  the
Declaration of Trust currently in effect and as hereinafter amended:


                                    ARTICLE I

                                    FORMATION

         The Trust is a real estate investment trust within the meaning of Title
8. It is also  intended that the Trust shall carry on a business as a "qualified
REIT  subsidiary" as described in the REIT provisions of the Code (as defined in
Article VII below),  for so long as it is wholly owned by HRPT Properties  Trust
and thereafter shall qualify and carry on business as a "real estate  investment
trust"  as  described  therein.  The  Trust  shall not be deemed to be a general
partnership,  limited  partnership,  joint  venture,  joint  stock  company or a
corporation,  but nothing herein shall preclude the Trust from being treated for
tax  purposes  as an  association  under the Code;  nor  shall the  Trustees  or
shareholders  or any of them for any  purpose  be,  nor be deemed to be,  nor be
treated in any way whatsoever as, liable or responsible hereunder as partners or
joint venturers.


                                   ARTICLE II

                                      NAME

         The name of the Trust is:

                         Senior Housing Properties Trust

         Under  circumstances  in which the Board of  Trustees of the Trust (the
"Board of Trustees" or "Board") determines that the use of the name of the Trust
is not  practicable,  the Trust may use any  other  designation  or name for the
Trust. To the extent  permitted by Maryland law, the Board of Trustees may amend
the  Declaration  of Trust to change the name of the Trust without any action by
the shareholders.

<PAGE>
                                   ARTICLE III

                               PURPOSES AND POWERS

         Section 3.1 Purposes. The purposes for which the Trust is formed are to
invest in and to  acquire,  hold,  manage,  administer,  control  and dispose of
property and interests in property, including, without limitation or obligation,
engaging in business as a real estate investment trust under the Code.

         Section 3.2 Powers.  The Trust shall have all of the powers  granted to
real estate  investment  trusts by Title 8 and all other powers set forth in the
Declaration of Trust which are not inconsistent  with law and are appropriate to
promote and attain the purposes set forth in the Declaration of Trust.


                                   ARTICLE IV

                                 RESIDENT AGENT

         The name of the resident agent of the Trust in the State of Maryland is
James J. Hanks,  Jr.,  whose post office  address is c/o Ballard Spahr Andrews &
Ingersoll, LLP, 300 East Lombard Street, Baltimore, Maryland 21202. The resident
agent is a citizen of and resides in the State of Maryland. The Trust may change
such resident agent from time to time as the Board of Trustees shall  determine.
The Trust may have such  offices or places of  business  within or  outside  the
State of Maryland as the Board of Trustees may from time to time determine.


                                    ARTICLE V

                                BOARD OF TRUSTEES

         Section 5.1 Powers. Subject to any express limitations contained in the
Declaration of Trust or in the Bylaws, (a) the business and affairs of the Trust
shall be managed  under the direction of the Board of Trustees and (b) the Board
shall have full,  exclusive and absolute  power,  control and authority over any
and all  property  of the  Trust.  The Board may take any  action as in its sole
judgment and  discretion is necessary or appropriate to conduct the business and
affairs of the Trust.  The  Declaration  of Trust  shall be  construed  with the
presumption  in favor of the  grant of power and  authority  to the  Board.  Any
construction of the Declaration of Trust or determination  made in good faith by
the Board concerning its powers and authority hereunder shall be conclusive. The
enumeration and definition of particular  powers of the Trustees included in the
Declaration  of Trust or in the Bylaws shall in no way be construed or deemed by
inference or  otherwise  in any manner to exclude or limit the powers  conferred
upon the Board or the  Trustees  under the general laws of the State of Maryland
or any other applicable laws.

         The Board,  without any action by the shareholders of the Trust,  shall
have and may exercise, on behalf of the Trust, without limitation,  the power to
terminate  the status of the Trust as a real estate  investment  trust under the
Code; to determine  that  compliance  with any  restriction  or  limitations  on
ownership and transfers of shares of the Trust's  beneficial  interest set forth
in Article

                                       -2-

VII of the  Declaration of Trust is no longer required in order for the Trust to
qualify as a real estate investment trust; to adopt, amend and repeal Bylaws not
inconsistent  with law or this  Declaration  of Trust;  to elect officers in the
manner  prescribed in the Bylaws;  to solicit  proxies from holders of shares of
beneficial interest of the Trust; and to do any other acts and deliver any other
documents necessary or appropriate to the foregoing powers.

         Section 5.2  Number and Classification.

                  Section 5.2.1 The number of trustees of the Trust (hereinafter
the "Trustees") initially shall be two (2). On the first date on which the Trust
shall have more than one shareholder of record, the number of the Trustees shall
automatically  and without  further action by the Board of Trustees  increase to
five (5), which number may thereafter be increased or decreased  pursuant to the
Bylaws of the Trust; provided,  however, that no such increase or decrease shall
result in the Trust having fewer than three (3) or more than seven (7) Trustees.
Any  vacancies  in the Board of  Trustees  shall be filled by a majority  of the
Trustees then in office,  except that a majority of the entire Board of Trustees
must fill a vacancy resulting from an increase in the number of Trustees.

                  Section  5.2.2 On the first date on which the Trust shall have
more than one  shareholder of record,  the Board of Trustees shall be classified
into three  groups:  Group I, Group II and Group III.  The number of Trustees in
each group  shall be  determined  by the Board in  accordance  with the  Bylaws;
provided  that the  number of  Trustees  in any one group  shall not  exceed the
number of Trustees in any other group by more than one.  The Trustees in Group I
shall  serve for a term  ending  at the first  annual  meeting  of  shareholders
following  the end of the Trust's  fiscal year ending  December 31,  1999,  each
Trustee  in Group II shall  serve  for a term  ending  at the  following  annual
meeting of  shareholders  and the  Trustee  in Group III shall  serve for a term
ending  at the  second  following  annual  meeting  of  shareholders.  After the

                                   ARTICLE VI

                          SHARES OF BENEFICIAL INTEREST

         Section 6.1 Authorized  Shares.  The  beneficial  interest of the Trust
shall be divided into shares of beneficial  interest (the  "Shares").  The Trust
has authority to issue 50,000,000 Shares,  all of which are initially  comprised
of  common  shares of  beneficial  interest,  $.01 par value per share  ("Common
Shares").  If shares of one class are classified or reclassified  into shares of
another  class of shares  pursuant to this Article VI, the number of  authorized
shares of the former class shall be  automatically  decreased  and the number of
shares of the latter class shall be automatically increased, in each case by the
number of shares so classified or reclassified,  so that the aggregate number of
shares of  beneficial  interest of all classes  that the Trust has  authority to
issue shall not be more than the total number of shares of  beneficial  interest
set forth in the  second  sentence  of this  paragraph.  The Board of  Trustees,
without any action by the  shareholders of the Trust,  may amend the Declaration
of Trust from time to time to  increase  or  decrease  the  aggregate  number of
Shares or the  number of Shares  of any  class or  series,  including  preferred
shares of beneficial interest ("Preferred Shares"), that the Trust has authority
to issue.

         Section 6.2 Common  Shares.  Subject to the  provisions of Article VII,
each Common  Share shall  entitle the holder  thereof to one vote on each matter
upon which holders of Common Shares are entitled to vote.  The Board of Trustees
may  reclassify  any  unissued  Common  Shares  from time to time in one or more
classes or series of Shares.

         Section 6.3  Preferred  Shares.  The Board of Trustees may classify any
unissued Preferred Shares and reclassify any previously  classified but unissued
Preferred  Shares  of any  series  from time to time,  in one or more  series of
Shares.

         Section 6.4  Classified or  Reclassified  Shares.  Prior to issuance of
classified or reclassified  Shares of any class or series, the Board of Trustees
by resolution  shall (a) designate that class or series;  (b) specify the number
of Shares  to be  included  in the  class or  series;  (c) set,  subject  to the
provisions of Article VII, the preferences,  conversion or other rights,  voting
powers,  restrictions,  limitations  as to  dividends  or  other  distributions,
qualifications  and terms and conditions of redemption for each class or series;
and (d) cause the Trust to file articles supplementary with the State Department
of  Assessments  and Taxation of Maryland (the "SDAT").  Any of the terms of any
class or series of Shares set  pursuant to clause (c) of this Section 6.4 may be
made dependent upon

                                       -4-

facts  ascertainable  outside the Declaration of Trust (including the occurrence
of any event,  determination or action by the Trust or any other person or body)
and may vary among holders thereof, provided that the manner in which such facts
or variations  shall operate upon the terms of such class or series of Shares is
clearly and  expressly  set forth in the articles  supplementary  filed with the
SDAT.

         Section  6.5  Authorization  by Board of Share  Issuance.  The Board of
Trustees may  authorize the issuance from time to time of Shares of any class or
series, whether now or hereafter authorized, or securities or rights convertible
into Shares of any class or series,  whether now or  hereafter  authorized,  for
such  consideration  (whether  in  cash,  property,  past  or  future  services,
obligation  for future  payment or  otherwise) as the Board of Trustees may deem
advisable  (or  without   consideration),   subject  to  such   restrictions  or
limitations,  if any,  as may be set forth in this  Declaration  of Trust or the
Bylaws of the Trust.

         Section 6.6 Dividends and Distributions. The Board of Trustees may from
time  to  time  authorize  and  declare  to   shareholders   such  dividends  or
distributions,  in cash or other  assets  of the Trust or in  securities  of the
Trust or from any other source as the Board of Trustees in its discretion  shall
determine.  Shareholders  shall have no right to any  dividend  or  distribution
unless and until  authorized  and  declared  by the Board.  The  exercise of the
powers and rights of the Board of Trustees pursuant to this Section 6.6 shall be
subject  to the  provisions  of any  class  or  series  of  Shares  at the  time
outstanding.

         Section  6.7  General  Nature of Shares.  All Shares  shall be personal
property  entitling  the  shareholders  only to  those  rights  provided  in the
Declaration of Trust. The shareholders shall have no interest in the property of
the Trust and shall have no right to compel any partition, division, dividend or
distribution  of the  Trust or of the  property  of the  Trust.  The  death of a
shareholder  shall not terminate the Trust or affect its continuity nor give his
or her legal representative any rights whatsoever, whether against or in respect
of other shareholders, the Trustees or the trust estate or otherwise, except the
sole right to demand and, subject to the provisions of the Declaration of Trust,
the Bylaws and any  requirements of law, to receive a new certificate for Shares
registered  in the  name of  such  legal  representative,  in  exchange  for the
certificate  held by such  shareholder.  The  Trust  is  entitled  to  treat  as
shareholders  only those persons in whose names Shares are registered as holders
of Shares on the beneficial interest ledger of the Trust.

         Section 6.8 Fractional  Shares.  The Trust may,  without the consent or
approval of any shareholder,  issue fractional Shares, eliminate a fraction of a
Share by rounding up or down to a full Share,  arrange for the  disposition of a
fraction of a Share by the person  entitled to it or pay cash for the fair value
of a fraction of a Share.

         Section 6.9 Declaration and Bylaws. All shareholders are subject to the
provisions of the Declaration of Trust and the Bylaws of the Trust.

         Section  6.10  Divisions  and  Combinations  of  Shares.  Subject to an
express  provision  to the  contrary  in the  terms of any  class or  series  of
beneficial interest hereafter  authorized,  the Board of Trustees shall have the
power to  divide or  combine  the  outstanding  shares of any class or series of
beneficial interest, without a vote of shareholders.

         Section 7.2  Equity Shares.

                  Section  7.2.1  Ownership   Limitations.   During  the  period
commencing on the Initial Date and prior to the Restriction Termination Date:

                  (a)      Basic Restrictions.

                    (i) (1) No Person,  other than an Excepted  Holder and other
than HRPT, RMR and their  affiliates,  shall  Beneficially Own or Constructively
Own Equity  Shares in excess of the  Aggregate  Share  Ownership  Limit,  (2) no
Person,  other  than an  Excepted  Holder  and other  than  HRPT,  RMR and their

of  the  Common  Share   Ownership  Limit  and  (3)  no  Excepted  Holder  shall

Holder Limit for such Excepted Holder.

                    (ii) No Person  shall  Beneficially  or  Constructively  Own
Equity Shares to the extent that such  Beneficial or  Constructive  Ownership of
Equity Shares would result in the Trust being  "closely held" within the meaning
of Section 856(h) of the Code (without regard to whether the ownership  interest
is held during the last half of a taxable year), or otherwise failing to qualify
as a REIT (including,  but not limited to, Beneficial or Constructive  Ownership
that would result in the Trust owning (actually or  Constructively)  an interest
in a tenant that is described in Section  856(d)(2)(B) of the Code if the income
derived by the Trust from such  tenant  would cause the Trust to fail to satisfy
any of the gross income requirements of Section 856(c) of the Code).

                    (iii)  Subject to  Section  7.4,  notwithstanding  any other
provisions  contained herein, any Transfer of Equity Shares (whether or not such
Transfer is the result of a transaction  entered into through the  facilities of
the NYSE or any other  national  securities  exchange or automated  inter-dealer
quotation  system)  that,  if  effective,  would  result in Equity  Shares being
beneficially owned by less than 100 Persons  (determined under the principles of
Section  856(a)(5)  of the  Code)  shall  be void ab  initio,  and the  intended
transferee shall acquire no rights in such Equity Shares.

                  (b) Transfer in Trust. If any Transfer of Equity Shares occurs
which,  if  effective,  would  result  in  any  Person  Beneficially  Owning  or
Constructively Owning Equity Shares in violation of Section 7.2.1(a)(i) or (ii),

                    (i) then that  number of Equity  Shares  the  Beneficial  or
Constructive  Ownership  of which  otherwise  would cause such Person to violate
Section  7.2.1(a)(i)  or (ii)  (rounded up to the nearest  whole share) shall be
automatically  transferred to a Charitable Trust for the benefit of a Charitable
Beneficiary,  as described in Section 7.3, effective as of the close of business
on the  Business Day prior to the date of such  Transfer,  and such Person shall
acquire no rights in such Equity Shares; or

                    (ii) if the transfer to the  Charitable  Trust  described in
clause (i) of this sentence would not be effective for any reason to prevent the
violation of Section  7.2.1(a)(i)  or (ii),  then the Transfer of that number of
Equity Shares that otherwise would cause any Person to violate

                                       -9-
<PAGE>

Section 7.2.1(a)(i) or (ii) shall be void ab initio, and the intended transferee
shall acquire no rights in such Equity Shares.

                  Section 7.2.2 Remedies for Breach. If the Board of Trustees or
any duly authorized  committee thereof shall at any time determine in good faith
that a Transfer or other event has taken  place that  results in a violation  of
Section  7.2.1 or that a Person  intends to acquire or has  attempted to acquire
Beneficial  or  Constructive  Ownership  of any Equity  Shares in  violation  of
Section 7.2.1 (whether or not such violation is intended), the Board of Trustees
or a committee thereof shall take such action as it deems advisable to refuse to
give effect to or to prevent such  Transfer or other event,  including,  without
limitation,  causing the Trust to redeem Equity Shares,  refusing to give effect
to such Transfer on the books of the Trust or instituting  proceedings to enjoin
such Transfer or other event; provided, however, that any Transfers or attempted
Transfers  or other events in  violation  of Section  7.2.1 shall  automatically
result in the transfer to the  Charitable  Trust  described  above,  and,  where
applicable,  such  Transfer (or other event) shall be void ab initio as provided
above  irrespective  of any action (or non-action) by the Board of Trustees or a
committee thereof.

                  Section  7.2.3 Notice of Restricted  Transfer.  Any Person who
acquires or attempts or intends to acquire Beneficial  Ownership or Constructive
Ownership of Equity  Shares that will or may violate  Section  7.2.1(a),  or any
Person who would have owned  Equity  Shares  that  resulted in a transfer to the
Charitable  Trust  pursuant  to  the  provisions  of  Section  7.2.1(b),   shall
immediately  give written  notice to the Trust of such event,  or in the case of
such a proposed or attempted  transaction,  give at least 15 days prior  written
notice,  and shall provide to the Trust such other  information as the Trust may
request in order to determine the effect, if any, of such Transfer.

                  Section 7.2.4 Owners Required To Provide Information. From the
Initial Date and prior to the Restriction Termination Date:

                  (a)  every  owner of more  than five  percent  (or such  lower
percentage  as  required  by the Code or the  Treasury  Regulations  promulgated
thereunder) of the  outstanding  Equity Shares,  within 30 days after the end of
each taxable year,  shall give written  notice to the Trust stating the name and
address of such  owner,  the number of Equity  Shares  and other  Equity  Shares
Beneficially  Owned and a  description  of the manner in which  such  shares are
held. Each such owner shall provide to the Trust such additional  information as
the  Trust  may  request  in order to  determine  the  effect,  if any,  of such
Beneficial  Ownership on the Trust's  status as a REIT and to ensure  compliance
with the Aggregate Share Ownership Limit.

                  (b) each Person who is a Beneficial or  Constructive  Owner of
Equity  Shares and each  Person  (including  the  shareholder  of record) who is
holding  Equity Shares for a Beneficial or  Constructive  Owner shall provide to
the Trust such information as the Trust may request,  in good faith, in order to
determine the Trust's  status as a REIT and to comply with  requirements  of any
taxing authority or governmental authority or to determine such compliance.

                  Section 7.2.5 Remedies Not Limited.  Subject to Section 5.1 of
the Declaration of Trust,  nothing contained in this Section 7.2 shall limit the
authority  of the  Board of  Trustees  to take  such  other  action  as it deems
necessary  or  advisable  to  protect  the  Trust  and  the   interests  of  its
shareholders in preserving the Trust's status as a REIT.

                  Section  7.2.6  Ambiguity.  In the case of an ambiguity in the
application  of any of the  provisions  of this Section 7.2,  Section 7.3 or any
definition  contained in Section 7.1, the Board of Trustees shall have the power
to determine the  application  of the  provisions of this Section 7.2 or Section
7.3 with respect to any  situation  based on the facts known to it. In the event
Section  7.2 or 7.3  requires  an  action  by the  Board  of  Trustees  and  the
Declaration  of Trust fails to provide  specific  guidance  with respect to such
action, the Board of Trustees shall have the power to determine the action to be
taken so long as such action is not contrary to the  provisions of Sections 7.1,
7.2 or 7.3.

                  Section 7.2.7  Exceptions.

                  (a) Subject to Section 7.2.1(a)(ii), the Board of Trustees, in
its sole  discretion,  may exempt a Person from the  Aggregate  Share  Ownership
Limit and the Common Share Ownership  Limit, as the case may be, and may (but is
not required to) establish or increase an Excepted  Holder Limit for such Person
if:

                    (i) the Board of Trustees obtains such  representations  and
undertakings  from such Person as are reasonably  necessary to ascertain that no
individual's  Beneficial  or  Constructive  Ownership of such Equity Shares will
violate Section 7.2.1(a)(ii);

                    (ii) such  Person does not and  represents  that it will not
own,  actually  or  Constructively,  an  interest in a tenant of the Trust (or a
tenant of any entity  owned or  controlled  by the Trust)  that would  cause the
Trust to own,  actually or  Constructively,  more than a 9.9%  interest  (as set
forth in  Section  856(d)(2)(B)  of the  Code) in such  tenant  and the Board of
Trustees obtains such  representations  and undertakings from such Person as are
reasonably  necessary to ascertain  this fact (for this  purpose,  a tenant from
whom the Trust (or an entity owned or controlled  by the Trust)  derives (and is
expected to  continue to derive) a  sufficiently  small  amount of revenue  such
that,  in the opinion of the Board of Trustees,  rent from such tenant would not
adversely  affect the Trust's ability to qualify as a REIT, shall not be treated
as a tenant of the Trust); and

                    (iii) such Person  agrees that any  violation  or  attempted
violation  of such  representations  or  undertakings  (or other action which is
contrary to the  restrictions  contained in Sections  7.2.1 through  7.2.6) will
result in such Equity  Shares being  automatically  transferred  to a Charitable
Trust in accordance with Sections 7.2.1(b) and 7.3.

                  (b)  Prior to  granting  any  exception  pursuant  to  Section
7.2.7(a),  the Board of Trustees may require a ruling from the Internal  Revenue
Service,  or an  opinion  of  counsel,  in  either  case in form  and  substance
satisfactory  to the Board of  Trustees in its sole  discretion,  as it may deem
necessary or  advisable in order to determine or ensure the Trust's  status as a
REIT.  Notwithstanding  the  receipt  of any  ruling  or  opinion,  the Board of
Trustees may impose such conditions or  restrictions as it deems  appropriate in
connection with granting such exception.

                  (c) In determining  whether to grant any exemption pursuant to
Section 7.2.7(a),  the Board of Trustees may consider,  among other factors, (i)
the  general  reputation  and  moral  character  of  the  person  requesting  an
exemption, (ii) whether ownership of shares would be direct or through ownership
attribution,  (iii)  whether the person's  ownership  of shares would  adversely
affect the Trust's ability to acquire  additional  properties or engage in other
business and (iv) whether

                                      -11-
<PAGE>

granting an exemption  for the person  requesting an exemption  would  adversely
affect any of the Trust's existing contractual arrangements.

                  (d)  Subject to Section  7.2.1(a)(ii),  an  underwriter  which
participates  in a public  offering or a private  placement of Equity Shares (or
securities  convertible into or exchangeable for Equity Shares) may Beneficially
Own or  Constructively  Own Equity  Shares (or  securities  convertible  into or
exchangeable  for Equity  Shares)  in excess of the  Aggregate  Share  Ownership
Limit,  the Common Share  Ownership  Limit or both such limits,  but only to the
extent necessary to facilitate such public offering or private placement.

                  (e) The Board of Trustees may only reduce the Excepted  Holder
Limit for an  Excepted  Holder:  (1) with the written  consent of such  Excepted
Holder  at any  time,  or  (2)  pursuant  to the  terms  and  conditions  of the
agreements and undertakings entered into with such Excepted Holder in connection
with the establishment of the Excepted Holder Limit for that Excepted Holder. No
Excepted  Holder  Limit shall be reduced to a  percentage  that is less than the
Common Share  Ownership Limit for an Excepted Holder without the written consent
of such Excepted Holder.

                  Section 7.2.8 Increase in Aggregate Share Ownership and Common
Share Ownership Limits. The Board of Trustees may from time to time increase the
Common Share Ownership Limit and the Aggregate Share Ownership Limit.

                  Section 7.2.9 Legend. Each certificate for Equity Shares shall
bear substantially the following legend:

                  The  shares  evidenced  by this  certificate  are  subject  to
                  restrictions  on  Beneficial  and  Constructive  Ownership and
                  Transfer  for  the  purpose,  among  others,  of  the  Trust's
                  maintenance of its status as a Real Estate Investment Trust (a
                  "REIT")  under the Internal  Revenue Code of 1986,  as amended
                  (the  "Code").  Subject to certain  further  restrictions  and
                  except as  expressly  provided in the Trust's  Declaration  of
                  Trust,  (i) no Person may Beneficially or  Constructively  Own
                  Common  Shares of the Trust in excess of 9.8 percent (in value
                  or number of shares) of the  outstanding  Common Shares of the
                  Trust unless such Person is an Excepted  Holder (in which case
                  the Excepted Holder Limit shall be applicable); (ii) no Person
                  may  Beneficially or  Constructively  Own Equity Shares of the
                  Trust in  excess  of 9.8  percent  of the  value of the  total
                  outstanding Equity Shares of the Trust,  unless such Person is
                  an Excepted  Holder (in which case the  Excepted  Holder Limit
                  shall be  applicable);  (iii) no Person  may  Beneficially  or
                  Constructively  Own Equity  Shares  that  would  result in the
                  Trust being "closely held" under Section 856(h) of the Code or
                  otherwise  cause the Trust to fail to qualify  as a REIT;  and
                  (iv) no Person may  Transfer  Equity  Shares if such  Transfer
                  would  result in Equity  Shares  of the Trust  being  owned by
                  fewer  than  100  Persons.  Any  Person  who  Beneficially  or
                  Constructively   Owns   or   attempts   to   Beneficially   or
                  Constructively  Own Equity  Shares which cause or will cause a
                  Person to Beneficially or Constructively  Own Equity Shares in
                  excess  or  in  violation  of  the  above   limitations   must
                  immediately  notify the Trust.  If any of the  restrictions on
                  transfer or ownership are violated, the Equity

                                      -12-
<PAGE>

                  Shares represented hereby will be automatically transferred to
                  a Trustee of a Charitable Trust for the benefit of one or more
                  Charitable Beneficiaries.  In addition, upon the occurrence of
                  certain  events,  attempted  Transfers  in  violation  of  the
                  restrictions  described  above  may be  void  ab  initio.  All
                  capitalized  terms in this legend have the meanings defined in
                  the Trust's  Declaration of Trust,  as the same may be amended
                  from time to time, a copy of which, including the restrictions
                  on transfer and ownership, will be furnished to each holder of
                  Equity Shares of the Trust on request and without charge.

                  Instead of the foregoing  legend,  the  certificate  may state
that the Trust will  furnish a full  statement  about  certain  restrictions  on
transferability to a shareholder on request and without charge.

         Section 7.3  Transfer of Equity Shares in Trust.

                  Section 7.3.1 Ownership in Trust. Upon any purported  Transfer
or other event described in Section  7.2.1(b) that would result in a transfer of
Equity Shares to a Charitable  Trust, such Equity Shares shall be deemed to have
been  transferred  to the  Trustee  as  trustee  of a  Charitable  Trust for the
exclusive benefit of one or more Charitable Beneficiaries.  Such transfer to the
Trustee  shall be deemed to be  effective  as of the  close of  business  on the
Business Day prior to the purported  Transfer or other event that results in the
transfer to the Charitable Trust pursuant to Section 7.2.1(b). The Trustee shall
be appointed by the Trust and shall be a Person  unaffiliated with the Trust and
any Prohibited  Owner.  Each Charitable  Beneficiary  shall be designated by the
Trust as provided in Section 7.3.6.

                  Section  7.3.2  Status of Shares Held by the  Trustee.  Equity
Shares held by the Trustee shall be issued and outstanding  Equity Shares of the
Trust.  The  Prohibited  Owner  shall have no rights in the  shares  held by the
Trustee.  The Prohibited Owner shall not benefit  economically from ownership of
any shares held in trust by the  Trustee,  shall have no rights to  dividends or
other  distributions  and shall not possess  any rights to vote or other  rights
attributable to the shares held in the Charitable Trust.

                  Section 7.3.3  Dividend and Voting  Rights.  The Trustee shall
have all voting  rights  and rights to  dividends  or other  distributions  with
respect to Equity  Shares held in the  Charitable  Trust,  which rights shall be
exercised for the exclusive benefit of the Charitable Beneficiary.  Any dividend
or other  distribution  paid prior to the  discovery  by the Trust  that  Equity
Shares have been  transferred  to the Trustee shall be paid with respect to such
Equity Shares to the Trustee upon demand and any dividend or other  distribution
authorized  but unpaid shall be paid when due to the Trustee.  Any  dividends or
distributions  so paid  over to the  Trustee  shall  be  held in  trust  for the
Charitable  Beneficiary.  The Prohibited  Owner shall have no voting rights with
respect to shares held in the  Charitable  Trust and,  subject to Maryland  law,
effective  as of the date  that  Equity  Shares  have  been  transferred  to the
Trustee, the Trustee shall have the authority (at the Trustee's sole discretion)
(i) to  rescind  as void  any  vote  cast by a  Prohibited  Owner  prior  to the
discovery by the Trust that Equity Shares have been  transferred  to the Trustee
and (ii) to recast  such vote in  accordance  with the  desires  of the  Trustee
acting for the benefit of the Charitable Beneficiary; provided, however, that if
the Trust has already taken  irreversible  trust action,  then the Trustee shall
not have the authority

                                      -13-
<PAGE>

to rescind and recast such vote.  Notwithstanding the provisions of this Article
VII,  until the Trust has  received  notification  that Equity  Shares have been
transferred into a Charitable  Trust, the Trust shall be entitled to rely on its
share transfer and other shareholder  records for purposes of preparing lists of
shareholders  entitled  to  vote  at  meetings,  determining  the  validity  and
authority of proxies and otherwise conducting votes of shareholders.

                  Section  7.3.4  Sale of Shares by  Trustee.  Within 20 days of
receiving  notice from the Trust that Equity Shares have been transferred to the
Charitable Trust, the Trustee of the Charitable Trust shall sell the shares held
in the Charitable Trust to a person,  designated by the Trustee, whose ownership
of the shares will not violate the  ownership  limitations  set forth in Section
7.2.1(a).  Upon such sale,  the interest of the  Charitable  Beneficiary  in the
shares sold shall terminate and the Trustee shall distribute the net proceeds of
the sale to the Prohibited  Owner and to the Charitable  Beneficiary as provided
in this Section 7.3.4.  The Prohibited Owner shall receive the lesser of (1) the
price paid by the Prohibited  Owner for the shares or, if the  Prohibited  Owner
did not give  value for the  shares in  connection  with the event  causing  the
shares to be held in the Charitable  Trust (e.g., in the case of a gift,  devise
or other such  transaction),  the  Market  Price of the shares on the day of the
event  causing the shares to be held in the  Charitable  Trust and (2) the price
per share  received by the  Trustee  from the sale or other  disposition  of the
shares held in the  Charitable  Trust.  Any net sales  proceeds in excess of the
amount  payable  to the  Prohibited  Owner  shall  be  immediately  paid  to the
Charitable  Beneficiary.  If,  prior to the  discovery  by the Trust that Equity
Shares  have  been  transferred  to the  Trustee,  such  shares  are  sold  by a
Prohibited  Owner,  then (i) such  shares  shall be  deemed to have been sold on
behalf of the Charitable  Trust and (ii) to the extent that the Prohibited Owner
received an amount for such shares that exceeds the amount that such  Prohibited
Owner was entitled to receive pursuant to this Section 7.3.4,  such excess shall
be paid to the Trustee upon demand.

                  Section  7.3.5  Purchase  Right in Shares  Transferred  to the
Trustee.  Equity Shares  transferred to the Trustee shall be deemed to have been
offered for sale to the Trust,  or its  designee,  at a price per share equal to
the lesser of (i) the price per share in the  transaction  that resulted in such
transfer  to the  Charitable  Trust  (or,  in the case of a devise or gift,  the
Market  Price at the time of such  devise or gift) and (ii) the Market  Price on
the date the Trust,  or its designee,  accepts such offer.  The Trust shall have
the right to accept such offer until the Trustee has sold the shares held in the
Charitable  Trust pursuant to Section 7.3.4.  Upon such a sale to the Trust, the
interest of the Charitable  Beneficiary  in the shares sold shall  terminate and
the Trustee  shall  distribute  the net  proceeds of the sale to the  Prohibited
Owner.

                  Section  7.3.6  Designation  of Charitable  Beneficiaries.  By
written notice to the Trustee,  the Trust shall  designate one or more nonprofit
organizations to be the Charitable Beneficiary of the interest in the Charitable
Trust such that Equity Shares held in the Charitable Trust would not violate the
restrictions  set forth in  Section  7.2.1(a)  in the  hands of such  Charitable
Beneficiary.

         Section  7.4 NYSE  Transactions.  Nothing  in this  Article  VII  shall
preclude the settlement of any  transaction  entered into through the facilities
of the NYSE or any other national securities exchange or automated  inter-dealer
quotation system.  The fact that the settlement of any transaction  occurs shall
not  negate  the  effect  of any other  provision  of this  Article  VII and any
transferee in such a transaction  shall be subject to all of the  provisions and
limitations set forth in this Article VII.

                                      -14-

         Section 7.5 Enforcement.  The Trust is authorized  specifically to seek
equitable relief, including injunctive relief, to enforce the provisions of this
Article VII.

         Section 7.6 Non-Waiver. No delay or failure on the part of the Trust or
the Board of Trustees  in  exercising  any right  hereunder  shall  operate as a
waiver of any right of the Trust or the Board of  Trustees,  as the case may be,
except to the extent specifically waived in writing.


                                  ARTICLE VIII

                                  SHAREHOLDERS

         Section  8.1  Meetings.  There  shall  be  an  annual  meeting  of  the
shareholders,  to be held on proper  notice at such time (after the  delivery of
the annual report) and  convenient  location as shall be determined by or in the
manner prescribed in the Bylaws, for the election of the Trustees,  if required,
and for the  transaction of any other  business  within the powers of the Trust.
Except as otherwise  provided in the Declaration of Trust,  special  meetings of
shareholders  may be called in the manner  provided in the Bylaws.  Shareholders
meetings,  including the annual meeting and any special meetings,  may be called
only by the Board of  Trustees.  If there are no  Trustees,  the officers of the
Trust shall promptly call a special meeting of the shareholders entitled to vote
for the  election  of  successor  Trustees.  Any meeting  may be  adjourned  and
reconvened as the Trustees determine or as provided in the Bylaws.

         Section 8.2 Voting  Rights.  Subject to the  provisions of any class or
series of Shares then  outstanding,  the shareholders  shall be entitled to vote
only on the following  matters:  (a) election of Trustees as provided in Section
5.2 and the removal of Trustees as provided in Section 5.3; (b) amendment of the
Declaration  of Trust as provided in Article X; (c)  termination of the Trust as
provided in Section 12.2; (d) merger or consolidation of the Trust to the extent
required  by Title 8, or the sale or  disposition  of  substantially  all of the
Trust  Property,  as  provided in Article  XI; and (e) such other  matters  with
respect to which the Board of Trustees has adopted a resolution declaring that a
proposed  action is advisable and directing  that the matter be submitted to the
shareholders for approval or ratification.  Except with respect to the foregoing
matters,  no action taken by the  shareholders  at any meeting  shall in any way
bind the Board of Trustees.

         Section 8.3 Preemptive and Appraisal Rights.  Except as may be provided
by the Board of  Trustees  in setting the terms of  classified  or  reclassified
Shares pursuant to Section 6.4, or as may otherwise be provided by contract,  no
holder  of  Shares  shall,  as such  holder,  (a) have any  preemptive  right to
purchase  or  subscribe  for any  additional  Shares  of the  Trust or any other
security  of the  Trust  which it may  issue  or sell or (b)  have any  right to
require  the Trust to pay him the fair  value of his Shares in an  appraisal  or
similar proceeding.

         Section 8.4 Extraordinary  Actions.  Except as specifically provided in
Section  5.3  (relating  to removal of  Trustees)  and  subject to Section  8.5,
notwithstanding  any  provision of law  permitting or requiring any action to be
taken or authorized by the  affirmative  vote of the holders of a greater number
of votes,  any such action shall be effective  and valid if taken or approved by
(i) the affirmative vote of holders of Shares entitled to cast a majority of all
the votes entitled to be cast on

                                      -15-
<PAGE>

the matter,  or (ii) if Maryland law hereafter  permits the  effectiveness  of a
vote  described in this clause (ii), the  affirmative  vote of a majority of the
votes cast on the matter.

         Section  8.5  Board  Approval.  The  submission  of any  action  to the
shareholders for their  consideration  shall first be approved or advised by the
Board of Trustees,  and the shareholders  shall not otherwise be entitled to act
thereon.

         Section 8.6 Action By Shareholders Without a Meeting. To the extent, if
any,  permitted by the Bylaws of the Trust,  any action required or permitted to
be taken by the  shareholders  may be taken  without  a meeting  by the  written
consent of the  shareholders  entitled to cast a  sufficient  number of votes to
approve  the matter as  required by  statute,  the  Declaration  of Trust or the
Bylaws of the Trust, as the case may be.


                                   ARTICLE IX

                      LIABILITY LIMITATION, INDEMNIFICATION
                         AND TRANSACTIONS WITH THE TRUST

         Section 9.1 Limitation of Shareholder  Liability.  No shareholder shall
be liable for any debt,  claim,  demand,  judgment or obligation of any kind of,
against or with respect to the Trust by reason of his being a  shareholder,  nor
shall any shareholder be subject to any personal liability whatsoever,  in tort,
contract or  otherwise,  to any person in  connection  with the  property or the
affairs of the Trust by reason of his being a shareholder.

         Section 9.2 Limitation of Trustee and Officer Liability. To the maximum
extent that  Maryland law in effect from time to time permits  limitation of the
liability of trustees and officers of a real estate investment trust, no current
or former Trustee or officer of the Trust shall be liable to the Trust or to any
shareholder for money damages.  Neither the amendment nor repeal of this Section
9.2, nor the adoption or amendment of any other  provision of the Declaration of
Trust  inconsistent  with  this  Section  9.2,  shall  apply to or affect in any
respect the  applicability of the preceding  sentence with respect to any act or
failure to act which occurred prior to such  amendment,  repeal or adoption.  In
the absence of any  Maryland  statute  limiting  the  liability  of trustees and
officers of a Maryland real estate  investment trust for money damages in a suit
by or on behalf of the Trust or by any shareholder,  or arising by reason of his
or her action on behalf of the Trust,  no Trustee or officer of the Trust  shall
be liable to the Trust or to any  shareholder  for money  damages  except to the
extent that (a) the Trustee or officer actually  received an improper benefit or
profit in money,  property or services,  for the amount of the benefit or profit
in money,  property or services  actually  received,  or (b) a judgment or other
final adjudication  adverse to the Trustee or officer is entered in a proceeding
based on a finding in the proceeding  that the Trustee's or officer's  action or
failure  to act was the  result  of active  and  deliberate  dishonesty  and was
material to the cause of action adjudicated in the proceeding.

         Section 9.3 Express  Exculpatory  Clauses and Instruments.  Any written
instrument creating an obligation of the Trust shall, to the extent practicable,
include  a  reference  to  this   Declaration   and  provide  that  neither  the
shareholders nor the Trustees nor any officers,  employees or agents  (including
the Trust's advisor,  the "Advisor") of the Trust shall be liable thereunder and
that all

                                      -16-
<PAGE>

persons  shall  look  solely to the trust  estate  for the  payment of any claim
thereunder  or for  the  performance  thereof;  however,  the  omission  of such
provision  from any such  instrument  shall not  render  the  shareholders,  any
Trustee, or any officer,  employee or agent (including the Advisor) of the Trust
liable,  nor shall the  shareholders,  any Trustee or any  officer,  employee or
agent  (including  the  Advisor)  of the  Trust be  liable  to  anyone  for such
omission.

         Section 9.4  Indemnification.  The Trust shall,  to the maximum  extent
permitted  by Maryland  law in effect from time to time,  indemnify,  and pay or
reimburse  reasonable  expenses in advance of final  disposition of a proceeding
to,  (a) any  individual  who is a present  or former  shareholder,  Trustee  or
officer of the Trust or (b) any individual who, while a Trustee of the Trust and
at the  request  of the  Trust,  serves or has  served as a  trustee,  director,
officer,  partner,  employee or agent of another real estate  investment  trust,
corporation,  partnership,  joint venture,  trust,  employee benefit plan or any
other  enterprise  from and against any claim or  liability to which such person
may become  subject or which such  person may incur by reason of his status as a
present or former shareholder,  Trustee or officer of the Trust. The Trust shall
have the power,  with the  approval of its Board of  Trustees,  to provide  such
indemnification and advancement of expenses to a person who served a predecessor
of the Trust in any of the  capacities  described in (a) or (b) above and to any
employee or agent of the Trust or a predecessor of the Trust.

         Section 9.5 Transactions Between the Trust and its Trustees,  Officers,
Employees  and Agents.  (a) Subject to any express  restrictions  adopted by the
Trustees in the Bylaws or by  resolution,  the Trust may enter into any contract
or  transaction  of any  kind,  whether  or not any of its  Trustees,  officers,
employees  or agents has a  financial  interest  in such  transaction,  with any
person,  including any Trustee,  officer,  employee or agent of the Trust or any
person affiliated with a Trustee,  officer, employee or agent of the Trust or in
which a  Trustee,  officer,  employee  or  agent  of the  Trust  has a  material
financial interest.

         (b) To the extent  permitted  by  Maryland  law,  a  contract  or other
transaction  between  the Trust and any  Trustee or between the Trust and RMR or
any other  corporation,  trust,  firm, or other entity in which any Trustee is a
director or trustee or has a material  financial  interest  shall not be void or
voidable if:

                  (i)  The  fact  of the  common  directorship,  trusteeship  or
         interest is disclosed or known to:

                           (A) The  Board  of  Trustees  or a  proper  committee
                  thereof,   and  the  Board  of  Trustees  or  such   Committee
                  authorizes,  approves or ratifies the contract or  transaction
                  by  the  affirmative  vote  of  a  majority  of  disinterested
                  Trustees,  even if the disinterested  Trustees constitute less
                  than a quorum; or

                           (B)  The  shareholders  entitled  to  vote,  and  the
                  contract or transaction is authorized,  approved,  or ratified
                  by a majority of the votes cast by the  shareholders  entitled
                  to vote  other  than the  votes of  shares  owned of record or
                  beneficially by the interested  trustee,  corporation,  trust,
                  firm or other entity; or

                           (C)  The   contract  or   transaction   is  fair  and
                  reasonable to the Trust.

                  (ii) Common or interested trustees or the shares owned by them
         or by an  interested  corporation,  trust,  firm or other entity may be
         counted in  determining  the  presence  of a quorum at a meeting of the
         Board  of  Trustees  or a  committee  thereof  or at a  meeting  of the
         shareholders,  as the case may be, at which the contract or transaction
         is authorized, approved or ratified.

         (c) The  failure of a contract or other  transaction  between the Trust
and any  Trustee or between the Trust and RMR or any other  corporation,  trust,
firm,  or other  entity in which any  Trustee is a director  or trustee or has a
material  financial interest to satisfy the criteria set forth in Section 9.5(b)
shall not create any  presumption  that such  contract or other  transaction  is
void, voidable or otherwise invalid,  and any such contract or other transaction
shall be valid to the fullest  extent  permitted by Maryland law. To the fullest
extent  permitted  by Maryland  law,  (i) the fixing by the Board of Trustees of
compensation  for a Trustee  (whether as a Trustee or in any other capacity) and
(ii) Section 9.4 of this  Declaration of Trust or any provision of the Bylaws or
any contract or transaction requiring or permitting  indemnification  (including
advancing of expenses) in accordance  with terms and  procedures  not materially
less  favorable  to the Trust than  those  described  in  Section  2-418 (or any
successor section thereto) of the Maryland General Corporation Law (as in effect
at the time such  provision  was  adopted or such  contract or  transaction  was
entered  into or as it may  thereafter  be in  effect)  shall be  deemed to have
satisfied the criteria set forth in Section 9.5(b).

         Section 9.6 Right of Trustees,  Officers,  Employees  and Agents to Own
Shares  or Other  Property  and to  Engage  in Other  Business.  Subject  to any
restrictions  which may be adopted by the  Trustees in the Bylaws or  otherwise:
Any Trustee or officer,  employee or agent of the Trust may acquire,  own,  hold
and dispose of Shares in the Trust, for his or her individual  account,  and may
exercise all rights of a  shareholder  to the same extent and in the same manner
as if he or she were not a Trustee or  officer,  employee or agent of the Trust.
Any  Trustee  or  officer,  employee  or agent of the Trust  may,  in his or her
personal capacity or in the capacity of trustee, officer, director, stockholder,
partner,  member, advisor or employee of any Person or otherwise,  have business
interests and engage in business  activities  similar to or in addition to those
relating to the Trust,  which  interests  and  activities  may be similar to and
competitive   with  those  of  the  Trust  and  may  include  the   acquisition,
syndication, holding, management, development, operation or disposition, for his
own  account,  or for the  account of such  Person or others,  of  interests  in
mortgages,  interests in real property,  or interests in Persons  engaged in the
real estate  business.  Each Trustee,  officer,  employee and agent of the Trust
shall  be  free  of any  obligation  to  present  to the  Trust  any  investment
opportunity  which  comes to him or her in any  capacity  other  than  solely as
Trustee,  officer, employee or agent of the Trust even if such opportunity is of
a character  which, if presented to the Trust,  could be taken by the Trust. Any
Trustee or officer, employee or agent of the Trust may be interested as trustee,
officer,  director,  stockholder,  partner,  member,  advisor or employee of, or
otherwise  have a direct or indirect  interest in, any Person who may be engaged
to render  advice or services to the Trust,  and may receive  compensation  from
such Person as well as  compensation as Trustee,  officer,  employee or agent or
otherwise  hereunder.  None of these activities shall be deemed to conflict with
his or her duties and powers as  Trustee or  officer,  employee  or agent of the
Trust.

         Section 9.7 Persons  Dealing  with  Trustees,  Officers,  Employees  or
Agents.  Any act of the Trustees or of the officers,  employees or agents of the
Trust purporting to be done in their capacity as such,  shall, as to any Persons
dealing with such Trustees, officers, employees or agents, be

                                      -18-
<PAGE>

conclusively  deemed to be within  the  purposes  of this  Trust and  within the
powers of such Trustees or officers, employees or agents. No Person dealing with
the Board or any of the  Trustees or with the  officers,  employees or agents of
the Trust  shall be bound to see to the  application  of any  funds or  property
passing  into their  hands or  control.  The  receipt of the Board or any of the
Trustees,  or of  authorized  officers,  employees  or agents of the Trust,  for
moneys or other consideration, shall be binding upon the Trust.

         Section 9.8  Reliance.  The Trustees and the  officers,  employees  and
agents of the Trust may consult  with  counsel and the advice or opinion of such
counsel shall be full and complete  personal  protection to all the Trustees and
the  officers,  employees and agents of the Trust in respect of any action taken
or suffered by them in good faith and in reliance on or in accordance  with such
advice or opinion. In discharging their duties, Trustees or officers,  employees
or agents of the  Trust,  when  acting in good  faith,  may rely upon  financial
statements  of the Trust  represented  to them to fairly  present the  financial
position or results of operations of the Trust by the chief financial officer of
the Trust or the officer of the Trust having charge of its books of account,  or
stated in a written report by an independent  certified public accountant fairly
to present the financial  position or results of  operations  of the Trust.  The
Trustees and the officers, employees and agents of the Trust may rely, and shall
be  personally  protected  in  acting,  upon any  instrument  or other  document
believed by them to be genuine.

                                    ARTICLE X

                                   AMENDMENTS

         Section 10.1 General. The Trust reserves the right from time to time to
make any amendment to the Declaration of Trust,  now or hereafter  authorized by
law, including any amendment altering the terms or contract rights, as expressly
set forth in the Declaration of Trust, of any Shares, except that the provisions
governing  the  personal  liability  of the  shareholders,  Trustees  and of the
officers,  employees and agents of the Trust and the  prohibition of assessments
upon  shareholders  may not be amended in any respect  that could  increase  the
personal  liability of such  shareholders,  Trustees or officers,  employees and
agents of the Trust. All rights and powers conferred by the Declaration of Trust

the Declaration of Trust shall include all amendments thereto.

         Section 10.2 By Trustees.  The Trustees may amend this  Declaration  of
Trust from time to time,  in the manner  provided by Title 8, without any action
by the shareholders, to qualify as a real estate investment trust under the Code
or under Title 8 and as  otherwise  provided in Section  8-501(e) of Title 8 and
the Declaration of Trust. If permitted by Maryland law as in effect from time to
time, the Trustees may amend this  Declaration of Trust from time to time in any
other  respect,  in  accordance  with  such  law,  without  any  action  by  the
shareholders.

effectiveness of a vote described in this clause (ii), the affirmative vote of a
majority of the votes cast on the matter.  Any amendment to Section 5.2.2 or 5.3

affirmative  vote of a  majority  of all the  votes  entitled  to be cast on the
matter or (ii) if Maryland law  hereafter  permits the  effectiveness  of a vote
described in this clause (ii), the  affirmative  vote of a majority of the votes

                                   ARTICLE XII

                        DURATION AND TERMINATION OF TRUST

         Section 12.1  Duration.  The Trust shall  continue  perpetually  unless

         Section 12.2  Termination.

                  (a) Subject to the provisions of any class or series of Shares
at the time  outstanding,  after  approval by a majority of the entire  Board of
Trustees,  the Trust may be terminated at any meeting of shareholders by (i) the
affirmative  vote of a  majority  of all the  votes  entitled  to be cast on the
matter or (ii) or if hereafter expressly  authorized by Title 8, the affirmative
vote of a majority of the votes cast on the matter.  Upon the termination of the
Trust:

                    (i) The Trust  shall  carry on no  business  except  for the
purpose of winding up its affairs.

                    (ii) The  Trustees  shall  proceed to wind up the affairs of
the Trust and all of the powers of the Trustees  under the  Declaration of Trust
shall  continue,  including  the  powers to  fulfill or  discharge  the  Trust's
contracts,  collect its assets,  sell,  convey,  assign,  exchange,  transfer or
otherwise  dispose of all or any part of the remaining  property of the Trust to
one or more  persons  at  public or  private  sale for  consideration  which may
consist in whole or in part of cash, securities

                                      -20-
<PAGE>

or other property of any kind, discharge or pay its liabilities and do all other
acts appropriate to liquidate its business.

                    (iii) After paying or  adequately  providing for the payment
of  all  liabilities,  and  upon  receipt  of  such  releases,  indemnities  and
agreements as they deem necessary for their protection, the Trust may distribute
the remaining property of the Trust among the shareholders so that after payment
in full or the setting apart for payment of such preferential  amounts,  if any,
to which the holders of any Shares at the time  outstanding  shall be  entitled,
the  remaining  property of the Trust  shall,  subject to any  participating  or
similar rights of Shares at the time outstanding,  be distributed  ratably among
the holders of Common Shares at the time outstanding.

                  (b) After  termination  of the Trust,  the  liquidation of its
business and the distribution to the shareholders as herein provided, a majority
of the  Trustees  shall  execute  and file with the  Trust's  records a document
certifying  that the Trust has been duly  terminated  and the Trustees  shall be
discharged  from all  liabilities  and  duties  hereunder,  and the  rights  and
interests of all shareholders shall cease.


                                  ARTICLE XIII

                                  MISCELLANEOUS

         Section 13.1  Governing  Law. The  Declaration of Trust is executed and
delivered with reference to the laws of the State of Maryland, and the rights of
all parties and the validity,  construction and effect of every provision hereof
shall  be  subject  to and  construed  according  to the  laws of the  State  of
Maryland.

         Section 13.2 Reliance by Third Parties.  Any certificate shall be final
and  conclusive  as to any  person  dealing  with the Trust if  executed  by the
Secretary or an Assistant Secretary of the Trust or a Trustee, and if certifying
to:  (a)  the  number  or  identity  of  Trustees,  officers  of  the  Trust  or
shareholders;  (b) the due  authorization of the execution of any document;  (c)
the action or vote taken,  and the  existence  of a quorum,  at a meeting of the
Board of Trustees or shareholders;  (d) a copy of the Declaration of Trust or of
the Bylaws as a true and complete copy as then in force; (e) an amendment to the
Declaration of Trust;  (f) the termination of the Trust; or (g) the existence of
any fact relating to the affairs of the Trust.  No purchaser,  lender,  transfer
agent or other person shall be bound to make any inquiry concerning the validity
of any  transaction  purporting  to be made by the Trust on its behalf or by any
officer, employee or agent of the Trust.

         Section 13.3  Severability.

                  (a) The provisions of the  Declaration of Trust are severable,
and if the Board of Trustees shall determine,  with the advice of counsel,  that
any one or  more  of  such  provisions  (the  "Conflicting  Provisions")  are in
conflict with the Code, Title 8 or other  applicable  federal or state laws, the
Conflicting Provisions,  to the extent of the conflict, shall be deemed never to
have constituted a part of the Declaration of Trust,  even without any amendment
of the  Declaration  of Trust  pursuant  to Article X and without  affecting  or
impairing  any of the  remaining  provisions  of the  Declaration  of  Trust  or
rendering invalid or improper any action taken or omitted (including but

                                      -21-
<PAGE>

not limited to the election of Trustees) prior to such determination. No Trustee
shall be liable for making or failing to make such a determination. In the event
of any such  determination  by the Board of Trustees,  the Board shall amend the
Declaration of Trust in the manner provided in Section 10.2.

                  (b) If any provision of the Declaration of Trust shall be held
invalid or unenforceable in any  jurisdiction,  such holding shall apply only to
the  extent  of any such  invalidity  or  unenforceability  and shall not in any
manner affect,  impair or render invalid or unenforceable  such provision in any
other  jurisdiction  or any other  provision of the  Declaration of Trust in any
jurisdiction.

         Section 13.4  Construction.  In the  Declaration  of Trust,  unless the
context otherwise requires,  words used in the singular or in the plural include
both the plural and singular and words  denoting any gender include all genders.
The title and headings of different parts are inserted for convenience and shall
not affect the meaning,  construction  or effect of the Declaration of Trust. In
defining or interpreting the powers and duties of the Trust and its Trustees and
officers,  reference  may be made by the  Trustees  or  officers,  to the extent
appropriate and not inconsistent with the Code or Title 8, to Titles 1 through 3
of the Corporations and Associations  Article of the Annotated Code of Maryland.
In furtherance  and not in limitation of the foregoing,  in accordance  with the
provisions of Title 3, Subtitles 6 and 7, of the  Corporations  and Associations
Article of the Annotated  Code of Maryland,  the Trust shall be included  within
the definition of "corporation" for purposes of such provisions.

         Section 13.5  Recordation.  The  Declaration of Trust and any amendment
hereto shall be filed for record with the SDAT and may also be filed or recorded
in such other places as the Trustees deem  appropriate,  but failure to file for
record the Declaration of Trust or any amendment hereto in any office other than
in  the  State  of  Maryland   shall  not  affect  or  impair  the  validity  or
effectiveness  of the Declaration of Trust or any amendment  hereto.  A restated
Declaration  of  Trust  shall,  upon  filing,  be  conclusive  evidence  of  all
amendments  contained  therein and may  thereafter be referred to in lieu of the
original Declaration of Trust and the various amendments thereto.

         THIRD:  The amendment to and restatement of the Declaration of Trust of
the Trust as  hereinabove  set forth  have  been  duly  advised  by the Board of
Trustees and approved by the shareholders of the Trust as required by law.

         FOURTH:  The total number of shares of  beneficial  interest  which the
Trust  has  authority  to  issue  has not been  amended  by this  amendment  and
restatement.

         The undersigned President  acknowledges these Articles of Amendment and
Restatement  to be the trust act of the  Trust,  and as to all  matters or facts
required to be verified under oath, the undersigned President acknowledges, that
to the best of his knowledge,  information  and belief,  these matters and facts
are true in all  material  respects  and that this  statement  is made under the

         Section 1.2 Additional  Offices.  The Trust may have additional offices
at such places as the Board of Trustees  may from time to time  determine or the
business of the Trust may require.

                                   ARTICLE II

                            MEETINGS OF SHAREHOLDERS

         Section 2.1 Place.  All meetings of  shareholders  shall be held at the
principal office of the Trust or at such other place within the United States as
is designated by the Trustees or the Chairman or President,  given either before
or after the meeting and filed with the Secretary of the Trust.

         Section 2.2 Annual Meeting.  An annual meeting of the  shareholders for
the election of Trustees and the  transaction of any business  within the powers
of the Trust  shall be held on the second  Thursday in May or such other date as

report,  referred to in Section  2.14,  at a  convenient  location and on proper
notice,  and at the  time set by the  Trustees,  beginning  with the year  2000.
Failure to hold an annual meeting does not  invalidate the Trust's  existence or
affect any otherwise valid acts of the Trust.

         Section 2.3 Special  Meetings.  Special meetings of shareholders may be
called only by a majority of the  Trustees.  If there shall be no Trustees,  the
officers of the Trust shall promptly call a special meeting of the  shareholders
entitled to vote for the election of successor  Trustees.  No business  shall be
transacted by the  shareholders at a special meeting other than business that is
either (i) specified in the notice of meeting (or any supplement  thereto) given
by or at the  direction  of the  Trustees  (or  any  duly  authorized  committee
thereof) or (ii) otherwise properly brought before the shareholders by or at the
direction of the Trustees.

         Section  2.4  Notice of Regular or  Special  Meetings.  Written  notice
specifying  the  place,  day and hour of any  regular or  special  meeting,  the
purposes of the meeting, and all other matters required by law shall be given to

copy thereof by mail,  telegraph or telecopier,  charges prepaid, to his address
appearing on the books of the Trust or theretofore given by him to the Trust for
the purpose of notice or, if no address appears or has been given,  addressed to
the place where the principal office of the Trust is situated.  If mailed,  such
notice shall be deemed to be given when  deposited in the U.S. mail addressed to
the  shareholder  at his post office address as it appears on the records of the
Trust, with

<PAGE>

postage thereon prepaid. It shall be the duty of the Secretary to give notice of
each Annual Meeting of the  Shareholders at least fifteen (15) days and not more
than sixty  (60) days  before  the date on which it is to be held.  Whenever  an
officer has been duly  requested  by the  Trustees to call a special  meeting of
shareholders,  it shall be his duty to fix the date and hour thereof, which date
shall be not less than  twenty (20) days and not more than sixty (60) days after
the receipt of such request,  and to give notice of such special  meeting within
ten (10) days after receipt of such request.

         Section 2.5 Notice of Adjourned Meetings.  It shall not be necessary to
give notice of the time and place of any adjourned meeting or of the business to
be transacted  thereat other than by  announcement  at the meeting at which such
adjournment is taken,  except that when a meeting is adjourned for more than 120
days after the original  record date,  notice of the adjourned  meeting shall be
given as in the case of an original meeting.

         Section 2.6 Scope of Notice.  No  business  shall be  transacted  at an
annual or special meeting of shareholders  except as specifically  designated in
the notice and otherwise  properly  brought before the shareholders by or at the
direction of the Trustees.

         Section 2.7 Organization of Shareholder  Meetings.  At every meeting of
the shareholders,  the chairman of the board, if there be one, shall conduct the
meeting  or, in the case of vacancy in office or absence of the  chairman of the
board,  one of the following  officers  present shall conduct the meeting in the
order stated:  the vice chairman of the board,  if there be one, the  president,
the vice  presidents in their order of rank and seniority,  or a chairman chosen
by  the  shareholders  entitled  to  cast a  majority  of the  votes  which  all
shareholders  present in person or by proxy are entitled to cast. The secretary,
or, in his  absence,  an  assistant  secretary,  or in the  absence  of both the
secretary and assistant  secretaries,  a person  appointed by the chairman shall
act as secretary for all shareholder meetings.

         Section 2.8 Quorum.  At any meeting of  shareholders,  the  presence in
person or by proxy of shareholders  entitled to cast a majority of all the votes
entitled to be cast at such meeting shall constitute a quorum;  but this section
shall not affect any  requirement  under any statute or the Declaration of Trust
for the vote necessary for the adoption of any measure. If, however, such quorum
shall not be  present  at any  meeting  of the  shareholders,  the  shareholders
entitled to vote at such meeting,  present in person or by proxy, shall have the
power to adjourn the meeting  from time to time to a date not more than 120 days
after the original  record  date.  At such  adjourned  meeting at which a quorum
shall  be  present,  any  business  may be  transacted  which  might  have  been
transacted at the meeting as originally notified.

         Section  2.9  Voting.  A majority of all the votes cast at a meeting of
shareholders duly called and at which a quorum is present shall be sufficient to
elect a Trustee.  Each share may be voted for as many  individuals  as there are
Trustees to be elected and for whose election the share is entitled to be voted.
A majority  of the votes cast at a meeting of  shareholders  duly  called and at
which a quorum is present  shall be sufficient to approve any other matter which
may properly  come before the meeting,  unless more than a majority of the votes
cast is required herein or by statute or by the Declaration of Trust.

                                       -2-

         Section 2.10 Proxies.  A shareholder  may cast the votes entitled to be
cast by the shares owned of record by him either in person or by proxy  executed
by the  shareholder or by his duly authorized  agent in any manner  permitted by
law.  Such proxy shall be filed with such  officer of the Trust as the  Trustees
shall have designated for such purpose for  verification  prior to such meeting.
Any proxy relating to the Trust's  shares of beneficial  interest shall be valid
until the expiration date therein or, if no expiration is so indicated, for such
period as is permitted  pursuant to Maryland law. At a meeting of  shareholders,
all questions  concerning the qualification of voters,  the validity of proxies,
and the  acceptance or rejection of votes,  shall be decided by the Secretary of
the meeting unless inspectors of election are appointed pursuant to Section 2.13
in which event such inspectors  shall pass upon all questions and shall have all
other duties specified in said section.

         Section 2.11 Voting  Rights.  The Board of Trustees  shall fix the date
for determination of shareholders entitled to vote at a meeting of shareholders.
If no date is fixed for the  determination of the shareholders  entitled to vote
at any meeting of  shareholders,  only persons in whose names shares entitled to
vote stand on the share  records of the Trust at the  opening of business on the
day of any meeting of shareholders shall be entitled to vote at such meeting.

         Section 2.12 Voting of Shares by Certain  Holders.  Shares of the Trust
registered in the name of a corporation,  partnership, trust or other entity, if
entitled  to be voted,  may be voted by the  president  or a vice  president,  a
general partner or trustee thereof,  as the case may be, or a proxy appointed by
any of the  foregoing  individuals,  unless  some  other  person  who  has  been
appointed  to vote  such  shares  pursuant  to a bylaw  or a  resolution  of the
governing board of such corporation or other entity or agreement of the partners
of the  partnership  presents a  certified  copy of such  bylaw,  resolution  or
agreement,  in which case such person may vote such shares. Any trustee or other
fiduciary may vote shares  registered in his name as such  fiduciary,  either in
person or by proxy.

         Shares of the Trust  directly  or  indirectly  owned by it shall not be
voted at any meeting and shall not be counted in determining the total number of
outstanding  shares entitled to be voted at any given time, unless they are held
by it in a  fiduciary  capacity,  in which  case  they may be voted and shall be
counted in determining the total number of outstanding shares at any given time.

         The Trustees may adopt by resolution a procedure by which a shareholder
may  certify in writing to the Trust that any shares  registered  in the name of
the  shareholder  are held for the account of a specified  person other than the
shareholder.  The resolution  shall set forth the class of shareholders  who may
make the certification, the purpose for which the certification may be made, the
form  of  certification  and  the  information  to be  contained  in it;  if the
certification  is with respect to a record date or closing of the share transfer
books,  the time after the record  date or closing of the share  transfer  books
within  which the  certification  must be received  by the Trust;  and any other
provisions with respect to the procedure which the Trustees  consider  necessary
or  desirable.  On receipt of such  certification,  the person  specified in the
certification  shall  be  regarded  as,  for  the  purposes  set  forth  in  the
certification, the shareholder of record of the specified shares in place of the
shareholder who makes the certification.

         Notwithstanding   any  other  provision  contained  herein  or  in  the
Declaration  of Trust or these Bylaws,  Title 3, Subtitle 7 of the  Corporations
and  Associations  Article of the  Annotated  Code of Maryland (or any successor
statute) shall not apply to any acquisition by any person of shares of

                                       -3-
<PAGE>

beneficial  interest of the Trust. This section may be repealed,  in whole or in
part, at any time, whether before or after an acquisition of control shares and,
upon such repeal,  may, to the extent provided by any successor bylaw,  apply to
any prior or subsequent control share acquisition.

         Section 2.13 Inspectors.  At any meeting of shareholders,  the chairman
of the meeting may appoint one or more persons as  inspectors  for such meeting.
Such inspectors  shall ascertain and report the number of shares  represented at
the  meeting  based  upon  their  determination  of the  validity  and effect of
proxies,  count all votes, report the results and perform such other acts as are
proper to conduct the election and voting at the meeting.

         Each report of an inspector shall be in writing and signed by him or by
a majority of them if there is more than one  inspector  acting at such meeting.
If there is more  than one  inspector,  the  report of a  majority  shall be the
report of the  inspectors.  The report of the  inspector  or  inspectors  on the
number of shares  represented at the meeting and the results of the voting shall
be prima facie evidence thereof.

         Section 2.14 Reports to Shareholders.  The Trustees shall submit to the
shareholders  at or before the annual  meeting of  shareholders  a report of the
business  and  operations  of the  Trust  during  such  fiscal  year  containing
financial  statements of the Trust,  accompanied by the report of an independent
certified public  accountant,  and such further  information as the Trustees may
determine is required  pursuant to any law or  regulation  to which the Trust is
subject.  Within  the  earlier of twenty  (20) days after the annual  meeting of
shareholders  or 120 days  after the end of the fiscal  year of the  Trust,  the
Trustees  shall place the annual report on file at the  principal  office of the
Trust and with any  governmental  agencies  as may be required by law and as the
Trustees may deem appropriate.

         Section 2.15  Nominations and Proposals by Shareholders.

                  Section   2.15.1   Annual   Meetings  of   Shareholders.   (a)
Nominations of persons for election to the Board of Trustees and the proposal of
business to be considered by the  shareholders  may be made at an annual meeting
of shareholders (i) pursuant to the Trust's notice of meeting, (ii) by or at the
direction  of the  Trustees or (iii) by any  shareholder  of the Trust who was a
shareholder of record both at the time of giving of notice  provided for in this
Section 2.15.1 and at the time of the annual meeting, who is entitled to vote at
the  meeting  and who  complied  with the  notice  procedures  set forth in this
Section 2.15.1.

                  (b) For  nominations or other business to be properly  brought
before an annual  meeting by a shareholder  pursuant to Section  2.15.1(a)(iii),
the  shareholder  must have  given  timely  notice  thereof  in  writing  to the
secretary of the Trust at the principal  executive offices of the Trust and such
other business must otherwise be a proper matter for action by  shareholders  as
determined by the Board of Trustees.  To be timely, a shareholder's notice shall
be delivered to the  secretary at the principal  executive  offices of the Trust
not later than the close of business on the 90th day nor earlier  than the close
of business  on the 120th day prior to the first  anniversary  of the  preceding
year's annual meeting; provided, however, that in the event that the date of the
annual meeting is advanced by more than thirty (30) days or delayed by more than
sixty (60) days from such  anniversary  date or if the Trust has not  previously
held an annual meeting, notice by the shareholder

                                       -4-
<PAGE>

to be timely must be so delivered  not earlier than the close of business on the
120th day prior to such annual  meeting and not later than the close of business
on the later of: (i) the 90th day prior to such annual meeting, or (ii) the 10th
day following the day on which public  announcement  of the date of such meeting
is first  made by the Trust.  In no event  shall the  public  announcement  of a
postponement  or  adjournment  of an  annual  meeting  to a  later  date or time
commence a new time period for the giving of a shareholder's notice as described
above.  A  shareholder's  notice  shall set forth (i) as to each person whom the
shareholder  proposes to nominate for election or reelection  as a Trustee,  all
information  relating  to  such  person  that is  required  to be  disclosed  in
solicitations of proxies for election of Trustees in an election contest,  or is
otherwise required, in each case pursuant to Regulation 14A under the Securities
Exchange Act of 1934, as amended (the "Exchange  Act"),  including such person's
written  consent  to being  named in the proxy  statement  as a  nominee  and to
serving  as a  Trustee  if  elected;  (ii) as to any  other  business  that  the
shareholder  proposes to bring before the meeting,  a brief  description  of the
business  desired to be brought  before the meeting,  the reasons for conducting
such business at the meeting and any material  interest in such business of such
shareholder and of the beneficial owner, if any, on whose behalf the proposal is
made;  and (iii) as to the  shareholder  giving the  notice  and the  beneficial
owner,  if any, on whose behalf the nomination or proposal is made, (x) the name
and address of such  shareholder,  as they appear on the Trust's  books,  and of
such  beneficial  owner and (y) the  number of each class of shares of the Trust
which  are  owned  beneficially  and of  record  by such  shareholder  and  such
beneficial owner.

                  (c) Notwithstanding anything in the second sentence of Section
2.15.1(b)  to the  contrary,  in the event  that the  number of  Trustees  to be
elected  to  the  Board  of  Trustees  is  increased  and  there  is  no  public
announcement  by the Trust naming all of the nominees for Trustee or  specifying
the size of the  increased  Board of Trustees  at least one  hundred  (100) days
prior to the  first  anniversary  of the  preceding  year's  annual  meeting,  a
shareholder's  notice  required by this Section  2.15.1 shall also be considered
timely,  but only with respect to nominees for any new positions created by such
increase,  if it shall be delivered to the secretary at the principal  executive
offices  of the  Trust  not later  than the  close of  business  on the 10th day
following the day on which such public announcement is first made by the Trust.

                  Section 2.15.2  Special  Meetings of  Shareholders.  Only such
business shall be conducted at a special  meeting of  shareholders as shall have
been  brought  before the meeting  pursuant  to the  Trust's  notice of meeting.
Nominations  of persons for  election to the Board of Trustees  may be made at a
special meeting of shareholders at which Trustees are to be elected (i) pursuant
to the Trust's  notice of meeting,  (ii) by or at the  direction of the Board of
Trustees or (iii),  provided  that the Board of  Trustees  has  determined  that
Trustees  shall be elected at such special  meeting,  by any  shareholder of the
Trust  who was a  shareholder  of  record  both at the time of  giving of notice
provided for in this Section 2.15.2 and at the time of the special meeting,  who
is entitled to vote at the meeting and who complied  with the notice  procedures
set forth in this Section 2.15.2. In the event the Trust calls a special meeting
of shareholders for the purpose of electing one or more Trustees to the Board of
Trustees, any such shareholder may nominate a person or persons (as the case may
be) for election to such position as specified in the Trust's notice of meeting,
if the  shareholder's  notice  containing  the  information  required by Section
2.15.1(b) shall be delivered to the secretary at the principal executive offices
of the Trust not  earlier  than the close of  business on the 120th day prior to
such  special  meeting and not later than the close of business on the later of:
(i) the 90th day prior to such special  meeting,  or (ii) the 10th day following
the day on which public

                                       -5-
<PAGE>

announcement  is  first  made of the  date  of the  special  meeting  and of the
nominees  proposed by the  Trustees to be elected at such  meeting.  In no event
shall the public  announcement  of a  postponement  or  adjournment of a special
meeting to a later date or time  commence a new time  period for the giving of a
shareholder's notice as described above.

                  Section  2.15.3  General.   (1)  Only  such  persons  who  are
nominated in accordance with the procedures set forth in this Section 2.15 shall
be eligible to serve as Trustees and only such business  shall be conducted at a
meeting  of  shareholders  as shall  have been  brought  before  the  meeting in
accordance  with the  procedures set forth in this Section 2.15. The chairman of
the meeting  shall have the power and duty to determine  whether a nomination or
any business proposed to be brought before the meeting was made or proposed,  as
the case may be, in  accordance  with the  procedures  set forth in this Section
2.15 and, if any proposed  nomination or business is not in compliance with this
Section 2.15, to declare that such nomination or proposal shall be disregarded.

                  (2) For purposes of this Section 2.15,  "public  announcement"
shall mean disclosure in a press release reported by the Dow Jones News Service,
Associated  Press or comparable news service or in a document  publicly filed by
the Trust with the Securities and Exchange Commission pursuant to Section 13, 14
or 15(d) of the Exchange Act.

                  (3) Notwithstanding  the foregoing  provisions of this Section
2.15, a shareholder shall also comply with all applicable  requirements of state
law and of the  Exchange  Act and the  rules  and  regulations  thereunder  with
respect to the matters set forth in this Section  2.15.  Nothing in this Section
2.15 shall be deemed to affect any right of a shareholder  to request  inclusion
of a  proposal  in,  nor the right of the  Trust to omit a  proposal  from,  the
Trust's proxy statement pursuant to Rule 14a-8 under the Exchange Act.

         Section 2.16 No Shareholder  Actions by Written  Consent.  Shareholders
shall not be authorized or permitted to take any action required or permitted to
be taken at a meeting  of  shareholders  by written  consent,  and may take such
action only at an annual or special  meeting as provided by Maryland law and the
Declaration of Trust and hereby.

         Section  2.17  Voting  by  Ballot.  Voting  on any  question  or in any
election may be viva voce unless the chairman of the meeting officer shall order
or any shareholder shall demand that voting be by ballot.

                                   ARTICLE III

                                    TRUSTEES

         Section 3.1 General Powers; Qualifications;  Trustees Holding Over. The
business  and affairs of the Trust shall be managed  under the  direction of its
Board of Trustees.  A Trustee shall be an individual  at least  twenty-one  (21)
years of age who is not under  legal  disability.  In case of  failure  to elect
Trustees at an annual  meeting of the  shareholders,  the Trustees  holding over
shall continue to direct the management of the business and affairs of the Trust
until their successors are elected and qualify.

                                       -6-

         Section 3.2 Independent  Trustees.  A majority of the Trustees  holding
office shall at all times be Independent Trustees (as defined below);  provided,
however,  that upon a failure to comply with this requirement as a result of the
creation of a temporary vacancy which must be filled by an Independent  Trustee,
whether as a result of enlargement of the Board of Trustees or the  resignation,
removal or death of a Trustee who is an Independent  Trustee,  such  requirement
shall not be applicable. An Independent Trustee is one who is not an employee of
the Trust's  investment  advisor (as  defined in Article  XIII),  and who is not
involved in the Trust's day-to-day activities.

         Section 3.3 Managing  Trustees.  Any Trustee who is not an  Independent
Trustee may be designated a Managing Trustee by the Board of Trustees.

         Section 3.4 Number.  At any regular  meeting or at any special  meeting
called  for that  purpose,  a  majority  of the  entire  Board of  Trustees  may
establish, increase or decrease the number of Trustees.

         Section  3.5  Annual and  Regular  Meetings.  An annual  meeting of the
Trustees  shall be held  immediately  after and at the same  place as the annual
meeting of shareholders,  no notice other than this Bylaw being  necessary.  The
time and place of the annual meeting of the Trustees may be changed by the Board
of Trustees. The Trustees may provide, by resolution, the time and place, either
within or without the State of Maryland,  for the holding of regular meetings of
the Trustees without other notice than such resolution.

         Section 3.6 Special  Meetings.  Special meetings of the Trustees may be
called at any time by the  chairman of the board,  any  Managing  Trustee or the
president and shall be called by request of any two (2) Trustees then in office.
The person or persons  authorized  to call special  meetings of the Trustees may
fix any place, either within or without the State of Maryland,  as the place for
holding any special meeting of the Trustees called by them.

         Section 3.7 Notice.  Notice of any  special  meeting  shall be given by
written  notice  delivered  personally,  telegraphed,  facsimile-transmitted  or
mailed  to  each  Trustee  at his  business  or  residence  address.  Personally
delivered or telegraphed  notices shall be given at least twenty-four (24) hours
prior to the meeting.  Notice by mail shall be deposited in the U.S. mail in the
place in which the principal office of the Trust is located at least seventy-two
(72) hours prior to the  meeting.  Telephone  or  facsimile-transmission  notice
shall be given at least forty-eight (48) hours prior to the meeting.  If mailed,
such notice shall be deemed to be given when deposited in the U.S. mail properly
addressed, with postage thereon prepaid. If given by telegram, such notice shall
be deemed to be given when the telegram is delivered to the  telegraph  company.
Telephone notice shall be deemed given when the Trustee is personally given such
notice in a telephone call to which he is a party. Facsimile-transmission notice
shall be deemed given upon completion of the  transmission of the message to the
number given to the Trust by the Trustee and receipt of a completed answer- back
indicating  receipt.  Neither the business to be transacted  at, nor the purpose
of, any annual, regular or special meeting of the Trustees need be stated in the
notice, unless specifically required by statute or these Bylaws.

         Section  3.8 Quorum.  A majority of the  Trustees  shall  constitute  a
quorum for  transaction  of business at any  meeting of the  Trustees,  provided
that, if less than a majority of such Trustees are

                                       -7-
<PAGE>

present at a meeting, a majority of the Trustees present may adjourn the meeting
from time to time without further notice, and provided further that if, pursuant
to the  Declaration  of Trust  or these  Bylaws,  the  vote of a  majority  of a
particular  group of Trustees is required for action, a quorum must also include
a majority of such group.

         The  Trustees  present  at a meeting  which has been  duly  called  and
convened may continue to transact  business until  adjournment,  notwithstanding
the withdrawal of enough Trustees to leave less than a quorum.

         Section 3.9 Voting.  The action of the majority of the Trustees present
at a meeting at which a quorum is present  shall be the action of the  Trustees,
unless the  concurrence  of a greater  proportion is required for such action by
specific provision of an applicable  statute,  the Declaration of Trust or these
Bylaws.

         Section 3.10 Telephone Meetings.  Trustees may participate in a meeting
by means of a conference  telephone or similar  communications  equipment if all
persons  participating  in the  meeting  can hear each  other at the same  time.
Participation in a meeting by these means shall constitute presence in person at
the  meeting.  Such  meeting  shall  be  deemed  to  have  been  held at a place
designated by the Trustees at the meeting.

         Section 3.11 Informal Action by Trustees. Unless specifically otherwise
provided in the  Declaration  of Trust,  any action  required or permitted to be
taken at any  meeting  of the  Trustees  may be taken  without a  meeting,  if a
majority of the Trustees shall  individually or collectively  consent in writing
to such action. Such written consent or consents shall be filed with the records
of the Trust and shall have the same force and effect as the affirmative vote of
such  Trustees  at a duly held  meeting  of the  Trustees  at which a quorum was
present.

         Section 3.12 Waiver of Notice.  The actions taken at any meeting of the
Trustees,  however  called and  noticed or wherever  held,  shall be as valid as
though taken at a meeting duly held after regular call and notice if a quorum is
present and if,  either  before or after the  meeting,  each of the Trustees not
present  signs a written  waiver of  notice,  a consent  to the  holding of such
meeting or an approval of the minutes  thereof.  All such  waivers,  consents or
approvals  shall be lodged with the Trust  records or made a part of the minutes
of the meeting.

         Section  3.13  Vacancies;  Groups.  If for  any  reason  any or all the
Trustees  cease to be  Trustees,  such event  shall not  terminate  the Trust or
affect these Bylaws or the powers of the remaining  Trustees  hereunder (even if
fewer than three (3)  Trustees  remain).  Any  vacancy  shall be filled,  at any
regular meeting or at any special meeting called for that purpose, by a majority
of the remaining  Trustees,  except that a vacancy resulting from an increase in
the  number of  Trustees  shall be filled by a majority  of the entire  Board of
Trustees.  Any  individual  so  elected as  Trustee  shall  hold  office for the
unexpired term of the Trustee he is replacing.

         On the  first  date on  which  the  Trust  shall  have  more  than  one
shareholder of record (the "Distribution Date"), the number of Trustees in Group
I shall be one (1), the number of Trustees in Group II shall be two (2), and the
number of  Trustees in Group III shall be two (2) (each of Group I, Group II and
Group  III  being  referred  to  herein  as a  "Group").  On  or  prior  to  the
Distribution

                                       -8-
<PAGE>

Date, a majority of the entire Board of Trustees  shall  designate  the Group of
which each  Trustee in office on the  Distribution  Date  shall  initially  be a
member, subject to the limitations contained in Section 5.2.2 of the Declaration
of Trust.  The term of a Trustee  elected  to fill any  vacancy  on the Board of
Trustees on the  Distribution  Date or at any time thereafter  shall be set by a
majority of the Board of Trustees  when the  position is created or, in the case
of vacancies existing on the Distribution Date, when such position is filled, by
designating  the new position as Group I, Group II or Group III,  subject to the
limitations contained in Section 5.2.2 of the Declaration of Trust. In the event
a vacancy on the Board of Trustees is filled by vote of shareholders pursuant to
Article II and the  Declaration  of Trust  rather  than by the Board of Trustees
pursuant  to this  Section  3.13,  the term of a  Trustee  elected  to fill such
vacancy shall be set by a majority of the Board of Trustees prior to the date on
which  notice of the  annual  meeting of  shareholders  at which such vote is to
occur or the  special  meeting of  shareholders  called for the  purpose of such
vote, as applicable, is given, by designating the new position as Group I, Group
II or Group III,  subject to the  limitations  contained in Section 5.2.2 of the
Declaration of Trust.  In the event the Trustees reduce the size of the Board of
Trustees on or after the Distribution  Date, the majority of the entire Board of
Trustees  shall reduce the size of one or more Group or Groups by the  aggregate
reduction in the number of the Trustees, subject to the limitations contained in
Section 5.2.2 of the Declaration of Trust. On or prior to the Distribution Date,
a majority of the entire Board of Trustees  shall  designate  the Group of which
each Trustee in office on the Distribution Date shall initially be a member.

                  Section 3.14.1 Compensation. The Trustees shall be entitled to
receive  such  reasonable  compensation  for their  services  as Trustees as the
Trustees  may  determine  from  time to time.  Trustees  may be  reimbursed  for
expenses of attendance,  if any, at each annual,  regular or special  meeting of
the Trustees or of any committee  thereof;  and for their  expenses,  if any, in
connection with each property visit and any other service or activity  performed
or engaged in as Trustee. The Trustees shall be entitled to receive remuneration
for services rendered to the Trust in any other capacity,  and such services may
include, without limitation, services as an officer of the Trust, services as an
employee of the Advisor (as defined in Article XIII), legal, accounting or other
professional  services, or services as a broker,  transfer agent or underwriter,
whether performed by a Trustee or any person affiliated with a Trustee.

                  Section 3.14.2 Financial Assistance to Trustees. The Trust may
lend money to,  guarantee an  obligation  of or otherwise  assist a Trustee or a
trustee of its  direct or  indirect  subsidiary.  The loan,  guarantee  or other
assistance may be with or without interest,  unsecured, or secured in any manner
that the Board of Trustees approves, including a pledge of shares.

         Section 3.15 Removal of Trustees.  The  shareholders  may, at any time,
remove any Trustee in the manner provided in the Declaration of Trust.

         Section 3.16 Loss of Deposits.  No Trustee shall be liable for any loss

loan  association,  or other  institution  with whom  moneys or shares have been
deposited.

Trustee shall be obligated to give any bond or surety or other  security for the
performance of any of his duties.

         Section 3.18 Reliance. Each Trustee, officer, employee and agent of the
Trust shall,  in the  performance  of his duties with  respect to the Trust,  be
fully  justified  and  protected  with  regard to any act or  failure  to act in
reliance in good faith upon the books of account or other  records of the Trust,
upon an  opinion  of  counsel  or upon  reports  made to the Trust by any of its
officers  or  employees  or  by  the  Advisor  (as  defined  in  Article  XIII),
accountants, appraisers or other experts or consultants selected by the Trustees
or officers of the Trust,  regardless of whether such counsel or expert may also
be a Trustee.

         Section 3.19  Interested  Trustee  Transactions.  Section  2-419 of the
Maryland  General  Corporation Law (the "MGCL") shall be available for and apply
to any contract or other  transaction  between the Trust and any of its Trustees

which any of its  Trustees is a trustee or director or has a material  financial
interest.

         Section  3.20  Qualifying  Shares Not  Required.  Trustees  need not be
shareholders of the Trust.

         Section  3.21  Certain  Rights of  Trustees,  Officers,  Employees  and

the  affairs of the Trust.  Any  Trustee or  officer,  employee  or agent of the
Trust, in his personal capacity or in a capacity as an affiliate,  employee,  or
agent of any other person, or otherwise,  may have business interests and engage
in  business  activities  similar or in  addition to those of or relating to the
Trust.

         Section 3.22 Certain Transactions.  Notwithstanding any other provision
in the Bylaws,  no  determination  shall be made by the  Trustees  nor shall any
transaction  be entered  into by the Trust which would cause any shares or other
beneficial  interest  in the Trust not to  constitute  "transferable  shares" or
"transferable  certificates of beneficial  interest" under Section  856(a)(2) of
the Internal  Revenue Code of 1986, as amended (the "Code") or which would cause
any  distribution to constitute a preferential  dividend as described in Section
562(c) of the Code.

Trustees.

         One-third, but not less than one, of the members of any committee shall
be present in person at any meeting of such  committee in order to  constitute a
quorum  for  the  transaction  of  business  at such  meeting,  and the act of a
majority  present  at a  meeting  at the time of such  vote if a quorum  is then
present shall be the act of such committee.  The Board of Trustees may designate
a  chairman  of any  committee,  and such  chairman  or any two  members  of any
committee  may fix the time and place of its  meetings  unless  the Board  shall
otherwise provide.  In the absence or disqualification of any member of any such
committee,  the members thereof present at any meeting and not disqualified from
voting, whether or not they constitute a quorum, may unanimously appoint another
Trustee  to act at the  meeting  in the  place of such  absent  or  disqualified
members.

         Each committee  shall keep minutes of its  proceedings and shall report
the same to the Board of Trustees at the next succeeding meeting, and any action

constitute presence in person at the meeting.

         Section  4.5  Informal  Action by  Committees.  Any action  required or
permitted to be taken at any meeting of a committee of the Trustees may be taken
without a meeting,  if a consent  in  writing  to such  action is signed by each
member of the  committee  and such written  consent is filed with the minutes of
proceedings of such committee.

         Section 4.6 Vacancies.  Subject to the provisions  hereof, the Board of
Trustees  shall  have the  power at any time to  change  the  membership  of any

president  and  vice  president  may  be  held  by the  same  person.  In  their
discretion,  the Trustees may leave unfilled any office except that of president
and  secretary.  Election  of an  officer  or agent  shall not of itself  create
contract rights between the Trust and such officer or agent.

         Section 5.2 Removal and Resignation.  Any officer or agent of the Trust
may be removed by the Trustees if in their  judgment  the best  interests of the
Trust would be served  thereby,  but such removal shall be without  prejudice to

may  resign  at any time by giving  written  notice  of his  resignation  to the
Trustees,  the  chairman  of the board,  the  president  or the  secretary.  Any
resignation  shall  take  effect at any time  subsequent  to the time  specified
therein or, if the time when it shall become effective is not specified therein,

necessary to make it effective unless otherwise stated in the resignation.  Such
resignation  shall be without  prejudice to the contract rights,  if any, of the
Trust.

         Section 6.1 Contracts.  The Trustees may authorize any officer or agent
to enter into any contract or to execute and deliver any  instrument in the name
of and on behalf of the Trust and such  authority  may be general or confined to
specific  instances.  Any  agreement,  deed,  mortgage,  lease or other document

                                     SHARES

         Section 7.1  Certificates.  Ownership  of shares  shall be evidenced by
certificates.   Each   shareholder   shall  be  entitled  to  a  certificate  or
certificates,  in such form as the  Trustees  shall  from time to time  approve,
which  shall  represent  and  certify  the  number of  shares  of each  class of
beneficial  interests held by him in the Trust.  Unless otherwise  determined by
the Trustees,  such certificates shall be signed by the chief executive officer,
the  president or a vice  president  and  countersigned  by the  secretary or an
assistant secretary or the treasurer or an assistant treasurer and may be sealed
with the seal,  if any, of the Trust.  The  signatures  may be either  manual or
facsimile.  Certificates shall be consecutively numbered; and if the Trust shall
from time to time issue several  classes of shares,  each class may have its own
number  series.  A  certificate  is valid  and may be issued  whether  or not an
officer  who signed it is still an officer  when it is  issued.  There  shall be
filed with each transfer  agent a copy of the form of certificate as approved by
the Trustees,  certified by the chairman,  president or secretary, and such form
shall continue to be used unless and until the Trustees approve some other form.
Each  certificate   representing   shares  which  are  restricted  as  to  their
transferability  or voting  powers,  which are  preferred or limited as to their
dividends or as to their  allocable  portion of the assets upon  liquidation  or
which are redeemable at the option of the Trust,  shall have a statement of such
restriction,  limitation,  preference  or  redemption  provision,  or a  summary
thereof,  plainly  stated  on the  certificate.  In lieu of  such  statement  or
summary,  the  Trust may set forth  upon the face or back of the  certificate  a
statement  that the Trust will  furnish to any  shareholder,  upon  request  and
without charge, a full statement of such information.

         Section 7.2 Transfers.  Certificates shall be treated as negotiable and
title thereto and to the shares they represent  shall be transferred by delivery
thereof to the same extent as those of a

                                      -14-

Maryland stock corporation. Upon surrender to the Trust or the transfer agent of
the Trust of a share certificate duly endorsed or accompanied by proper evidence
of succession,  assignment or authority to transfer, the Trust shall issue a new
certificate  to the person  entitled  thereto,  cancel the old  certificate  and
record the transaction upon its books.

         The Trust  shall be entitled to treat the holder of record of any share
or shares as the holder in fact thereof and, accordingly,  shall not be bound to
recognize any equitable or other claim to or interest in such share or shares on
the part of any other  person,  whether  or not it shall  have  express or other
notice  thereof,  except  as  otherwise  provided  by the  laws of the  State of
Maryland.

         Notwithstanding  the  foregoing,  transfers  of  shares  of  beneficial
interest  of the Trust will be subject in all  respects  to the  Declaration  of
Trust and all of the terms and conditions contained therein.

         Section 7.3  Replacement  Certificate.  Any officer  designated  by the
Trustees may direct a new  certificate to be issued in place of any  certificate
previously  issued by the Trust  alleged to have been lost,  stolen or destroyed
upon  the  making  of an  affidavit  of that  fact by the  person  claiming  the
certificate to be lost, stolen or destroyed.  When authorizing the issuance of a
new  certificate,  an officer  designated by the Trustees may, in his discretion
and as a condition precedent to the issuance thereof,  require the owner of such
lost,  stolen or destroyed  certificate or the owner's legal  representative  to
advertise the same in such manner as he shall require and/or to give bond,  with
sufficient  surety, to the Trust to indemnify it against any loss or claim which
may arise as a result of the issuance of a new certificate.

         Section  7.4 Closing of Transfer  Books or Fixing of Record  Date.  The
Trustees  may set,  in advance,  a record  date for the  purpose of  determining
shareholders  entitled to notice of or to vote at any meeting of shareholders or
determining  shareholders  entitled  to receive  payment of any  dividend or the
allotment  of  any  other  rights,  or in  order  to  make  a  determination  of
shareholders for any other proper purpose.

         In lieu of fixing a record  date,  the  Trustees  may provide  that the
share  transfer  books  shall be closed for a stated  period but not longer than
twenty  (20) days.  If the share  transfer  books are closed for the  purpose of
determining  shareholders  entitled  to  notice  of or to vote at a  meeting  of
shareholders,  such books  shall be closed for at least ten (10) days before the
date of such meeting.

         If no record date is fixed and the share  transfer books are not closed
for the determination of shareholders, (a) the record date for the determination
of  shareholders  entitled to notice of or to vote at a meeting of  shareholders
shall be at the close of  business  on the day on which the notice of meeting is
mailed or the 30th day before the  meeting,  whichever is the closer date to the
meeting; and (b) the record date for the determination of shareholders  entitled
to receive  payment of a dividend or an  allotment  of any other rights shall be
the  close of  business  on the day on which  the  resolution  of the  Trustees,
declaring the dividend or allotment of rights, is adopted.

         When a determination of shareholders entitled to vote at any meeting of
shareholders has been made as provided in this section, such determination shall
apply to any adjournment thereof.

         Section 7.5 Share  Ledger.  The Trust shall  maintain at its  principal
office or at the office of its counsel,  accountants or transfer  agent, a share
ledger  containing  the name and address of each  shareholder  and the number of
shares of each class held by such shareholder.

         Section 7.6  Fractional  Shares;  Issuance of Units.  The  Trustees may
issue fractional  shares or provide for the issuance of scrip, all on such terms
and under  such  conditions  as they may  determine.  Notwithstanding  any other

securities of the Trust issued in such unit may be  transferred  on the books of
the Trust only in such unit.

                     INDEMNIFICATION AND ADVANCE OF EXPENSES

         To the maximum extent  permitted by Maryland law in effect from time to
time, the Trust shall  indemnify (a) any Trustee,  officer or shareholder or any
former Trustee,  officer or shareholder (including among the foregoing,  for all
purposes of this Article XI and without limitation,  any individual who, while a
Trustee,  officer or shareholder and at the express request of the Trust, serves
or has served another real estate  investment trust,  corporation,  partnership,
joint  venture,  trust,  employee  benefit  plan or any  other  enterprise  as a
director,  officer,  shareholder,   partner  or  trustee  of  such  real  estate
investment  trust,  corporation,  partnership,  joint venture,  trust,  employee
benefit  plan or other  enterprise)  who has been  successful,  on the merits or
otherwise, in the defense of a proceeding to which he was made a party by reason
of service in such  capacity,  against  reasonable  expenses  incurred by him in
connection with the proceeding, (b) any Trustee or officer or any former Trustee
or officer  against  any claim or  liability  to which he may  become  liable or
subject  by  reason of such  status or  actions  in such  capacity  and (c) each
shareholder or former shareholder against any claim or liability to which he may
become subject by reason of such status. In addition,  the Trust shall,  without
requiring  a  preliminary   determination   of  the  ultimate   entitlement   to
indemnification,  pay  or  reimburse,  in  advance  of  final  disposition  of a
proceeding, reasonable expenses incurred by a Trustee, officer or shareholder or
former  Trustee,  officer or shareholder  made a party to a proceeding by reason
such status, provided that, in the case of a Trustee or officer, the Trust shall
have  received (i) a written  affirmation  by the Trustee or officer of his good
faith belief that he has met the  applicable  standard of conduct  necessary for
indemnification  by the Trust as  authorized  by Maryland law and (ii) a written
undertaking  by him or on his behalf to repay the amount paid or  reimbursed  by
the Trust if it shall  ultimately be determined that the applicable  standard of
conduct was not met. The Trust may, with the approval of its  Trustees,  provide
such  indemnification  or payment or  reimbursement  of expenses to any Trustee,
officer or shareholder or any former Trustee,  officer or shareholder who served
a  predecessor  of the  Trust  and to any  employee  or agent of the  Trust or a
predecessor of the Trust.  Neither the amendment nor repeal of this Article, nor
the adoption or amendment of any other  provision of the Declaration of Trust or
these Bylaws  inconsistent  with this  Article,  shall apply to or affect in any
respect the  applicability of this Article with respect to any act or failure to
act which occurred prior to such amendment, repeal or adoption.

         Any  indemnification  or  payment  or  reimbursement  of  the  expenses
permitted by these Bylaws shall be furnished in accordance  with the  procedures
provided for  indemnification  or payment or reimbursement  of expenses,  as the
case  may be,  under  Section  2-418  of the  MGCL  for  directors  of  Maryland
corporations.  The Trust may provide to Trustees, officers and shareholders such
other and further  indemnification  or payment or reimbursement of expenses,  as
the case may be, to the fullest extent  permitted by the MGCL, as in effect from
time to time, for directors of Maryland corporations.

                                   ARTICLE XII

                                WAIVER OF NOTICE

         Whenever any notice is required to be given pursuant to the Declaration
of Trust or Bylaws or pursuant to applicable  law, a waiver  thereof in writing,
signed by the person or persons entitled to such notice, whether before or after
the time  stated  therein,  shall be  deemed  equivalent  to the  giving of such
notice.  Neither the business to be transacted at nor the purpose of any meeting
need be set forth in the  waiver of  notice,  unless  specifically  required  by
statute.  The attendance of any person at any meeting shall  constitute a waiver
of notice of such  meeting,  except where such person  attends a meeting for the
express  purpose of objecting to the  transaction  of any business on the ground
that the meeting is not lawfully called or convened.

                                  ARTICLE XIII

                                   THE ADVISOR

         Section 13.1 Employment of Advisor.  The Trustees are not and shall not
be required  personally  to conduct the business of the Trust,  and the Trustees
shall have the power to appoint,  employ or contract with any person  (including
one or more of themselves or any corporation, partnership, or trust in which one
or more of them may be Trustees, officers,  stockholders,  partners or trustees)
as the Trustees may deem necessary or proper for the transaction of the business
of the Trust.  The Trustees may  therefore  employ or contract  with such person
(herein  referred to as the  "Advisor") and may grant or delegate such authority
to the Advisor as the Trustees may in their sole  discretion  deem  necessary or
desirable  without  regard to whether  such  authority  is  normally  granted or
delegated by boards of trustees or boards of directors of business corporations.
The Advisor shall be required to use its best efforts to supervise the operation
of the Trust in a manner consistent with the investment  policies and objectives
of the Trust as established from time to time by the Trustees.

         The  Trustees   shall  have  the  power  to  determine  the  terms  and
compensation  of the Advisor or any other  person whom it may cause the Trust to
employ or with whom it may cause the Trust to contract  for  advisory  services.
The Trustees may exercise broad discretion in allowing the Advisor to administer
and  regulate the  operations  of the Trust,  to act as agent for the Trust,  to
execute  documents  on behalf of the Trustees  and to make  executive  decisions
which conform to general policies and general principles previously  established
by the Trustees.

         Section  13.2 Other  Activities  of Advisor.  The Advisor  shall not be
required to administer the Trust as its sole and exclusive function and may have
other  business  interests  and may  engage in other  activities  similar  or in
addition to those  relating to the Trust,  including  the rendering of advice or
services of any kind to other  investors or any other persons  (including  other
real estate  investment  trusts) and the  management of other  investments.  The
Trustees  may request the Advisor to engage in certain  other  activities  which
complement the Trust's investments,  and the Advisor may receive compensation or
commissions therefor from the Trust or other persons.

         Neither the Advisor nor any affiliate of the Advisor shall be obligated
to present any particular  investment  opportunities to the Trust,  even if such
opportunities are of a character such

                                      -18-
<PAGE>

that, if presented to the Trust,  they could be taken by the Trust, and, subject
to the foregoing,  each of them shall be protected in taking for its own account
or recommending to others any such particular investment opportunity.

                                   ARTICLE XIV

                               AMENDMENT OF BYLAWS

         Except for any change for which the Declaration or these Bylaws require
approval  by more than a  majority  vote of the  Trustees,  these  Bylaws may be
amended or repealed or new or additional  Bylaws may be adopted only by the vote
or written consent of a majority of the Trustees.

                                   ARTICLE XV

                                  MISCELLANEOUS

         Section 15.1 References to Declaration of Trust.  All references to the
Declaration of Trust shall include any amendments thereto.

         Section  15.2  Inspection  of Bylaws.  The  Trustees  shall keep at the
principal  office for the transaction of business of the Trust the original or a
copy of the Bylaws as amended or  otherwise  altered to date,  certified  by the
Secretary,  which  shall  be  open  to  inspection  by the  shareholders  at all
reasonable times during office hours.

Senior Housing Properties Trust
400 Centre Street
Newton, Massachusetts  02458

Ladies and Gentlemen:

         In connection  with the filing by Senior  Housing  Properties  Trust, a
Maryland real estate  investment trust (the "Company"),  of its Annual Report on
Form 10-K for the year ended  December  31,  1999 (the "Form  10-K"),  under the
Securities  Exchange Act of 1934, as amended (the "Exchange Act"), the following
opinion  is  furnished  to you to be filed  with  the  Securities  and  Exchange
Commission (the "SEC") as Exhibit 8.1 to the Form 10-K.

         We have  acted  as  counsel  for the  Company  in  connection  with the
preparation  of its  Form  10-K,  and we  have  examined  originals  or  copies,
certified or otherwise  identified to our  satisfaction,  of corporate  records,
certificates  and  statements of officers and  accountants of the Company and of
public  officials,  and such other documents as we have considered  relevant and
necessary in order to furnish the opinion  hereinafter set forth.  Specifically,
and without limiting the generality of the foregoing,  we have reviewed: (i) the
declaration of trust,  as amended and restated,  and the by-laws of the Company,
as amended  and  restated;  and (ii) the  sections  in the  Company's  Form 10-K
captioned "Federal Income Tax  Considerations" and "ERISA Plans, Keogh Plans and
Individual  Retirement Accounts." With respect to all questions of fact on which
such opinions are based,  we have assumed the accuracy and  completeness  of and
have relied on the  information  set forth in the Form 10-K and in the documents
incorporated therein by reference, and on representations made to us by officers
of the Company. We have not independently verified such information.

         The opinion set forth below is based upon the Internal  Revenue Code of
1986,  as  amended,  the  Treasury  Regulations  issued  thereunder,   published
administrative  interpretations  thereof,  and judicial  decisions  with respect
thereto, all as of the date hereof (collectively,  the "Tax Laws"), and upon the
Employee  Retirement Income Security Act of 1974, as amended,  the Department of
Labor regulations issued thereunder,  published  administrative  interpretations
thereof,  and judicial decisions with respect thereto, all as of the date hereof
(collectively, the

"ERISA  Laws").  No  assurance  can be given that the Tax Laws or the ERISA Laws
will not change. In preparing the discussions with respect to Tax Laws and ERISA
Laws matters in the sections of the Annual Report captioned  "Federal Income Tax
Considerations"  and  "ERISA  Plans,  Keogh  Plans  and  Individual   Retirement
Accounts," we have made certain assumptions and expressed certain conditions and
qualifications therein, all of which assumptions,  conditions and qualifications
are incorporated herein by reference.

         Based upon and subject to the foregoing, we are of the opinion that the
discussions  with  respect to Tax Laws and ERISA Laws matters in the sections of
the Annual  Report  captioned  "Federal  Income Tax  Considerations"  and "ERISA
Plans, Keogh Plans and Individual Retirement Accounts," in all material respects
are  accurate  and fairly  summarize  the Tax Laws  issues and ERISA Laws issues
addressed  therein,  and hereby confirm that the opinions of counsel referred to
in said sections represent our opinions on the subject matter thereof.

         We hereby consent to the  incorporation of this opinion by reference as
an exhibit to the Form 10-K and to the reference of our firm therein.  In giving
such  consent,  we do not  thereby  admit that we come  within the  category  of
persons whose consent is required  under Section 7 of the Act or under the rules
and regulations of the SEC promulgated thereunder.

                                              Very truly yours,


                                              /s/ SULLIVAN & WORCESTER LLP
                                              SULLIVAN & WORCESTER LLP

         In  performing  its  services  under this  Agreement,  the  Advisor may
utilize facilities,  personnel and support services of various of its Affiliates
(as defined below).  The Advisor shall be responsible for paying such Affiliates
for their  personnel and support  services and  facilities out of its own funds.
Notwithstanding the above, the Company may request,  and will pay for the direct
costs of,  services  provided by  Affiliates  of the Advisor  provided that such
request is approved by a majority vote of the Trustees who are not Affiliates of
the Advisor (the "Independent Trustees").

         As  used in this  Agreement,  the  term  "Affiliate"  means,  as to the
Advisor,  (i) any  other  Person  (as  defined  below)  directly  or  indirectly
controlling,  controlled by or under common  control with the Advisor,  (ii) any
other Person that owns beneficially,  directly or indirectly,  five percent (5%)
or more of the  outstanding  capital  stock,  shares or equity  interests of the
Advisor, or (iii) any officer, director, trustee, employee or general partner of
the Advisor or of any Person controlling,  controlled by or under common control
with  the  Advisor.   The  term   "Person"   means  and  includes   individuals,
corporations,  limited  partnerships,  general  partnerships,  limited liability
companies, joint stock companies or associations,  joint ventures, associations,
companies,  trusts,  banks,  trust companies,  land trusts,  business trusts and
other entities.

         2. Bank Accounts.  The Advisor shall establish and maintain one or more
bank  accounts in its own name or in the name of the Company,  and shall collect
and deposit into the account or accounts and  disburse  therefrom  any monies on
behalf of the Company; provided that no funds in any account shall be commingled
with any funds of the Advisor or any other  Person.  The Advisor shall from time
to time render an  appropriate  accounting  of  collections  and payments to the
Trustees and to the auditors of the Company.

         3. Records. The Advisor shall maintain appropriate books of account and
records relating to services performed  pursuant to this Agreement,  which books
of account and records shall be available for inspection by  representatives  of
the Company upon reasonable notice during ordinary business hours.

         4. Information  Furnished Advisor. The Trustees shall at all times keep
the  Advisor  fully  informed  with  regard to the  investment  policies  of the

then-current  intentions  as to the future of the Company.  In  particular,  the
Company shall notify the Advisor  promptly of its intention to sell or otherwise
dispose of any of the Company's  investments or to make any new investment.  The
Company  shall  furnish  the  Advisor  with a  certified  copy of all  financial
statements,  a signed copy of each  report  prepared  by  independent  certified
public  accountants  and other  information  with  regard to its  affairs as the
Advisor may from time to time reasonably request. The Company shall retain legal
counsel and  accountants to provide legal and accounting  advice and services as
the Advisor or the Trustees  shall deem  necessary or  appropriate to adequately
perform  the  functions  of the  Company,  and shall  have  legal or  accounting

         5. REIT Qualification.  Anything else in this Agreement to the contrary
notwithstanding,  the Advisor shall refrain from any action (including,  without
limitation,  the  furnishing  or rendering of services to tenants of property or
managing real  property)  which,  in its judgment made in good faith,  or in the
judgment of the  Trustees as  transmitted  to the Advisor in writing,  would (a)
adversely

                                       -3-
<PAGE>

affect the status of the  Company as a real estate  investment  trust as defined
and limited in the Internal Revenue Code or which would make the Company subject
to the Investment Company Act of 1940, as amended, or (b) violate any law, rule,
regulation  or statement  of policy or any  governmental  body or agency  having
jurisdiction  over the Company or over its  securities,  or (c) otherwise not be
permitted by the  Declaration  of Trust or Bylaws of the  Company,  as in effect
from time to time,  except if the action  shall be ordered by the  Trustees,  in
which event the Advisor  shall  promptly  notify the  Trustees of the  Advisor's
judgment that the action would adversely  affect the Company's status or violate
any law, rule or regulation or the Declaration of Trust or Bylaws of the Company
and shall  refrain  from  taking the action  pending  further  clarification  or
instructions from the Trustees. In addition,  the Advisor shall take affirmative
steps  which,  in its  judgment  made in good faith,  or in the  judgment of the
Trustees as  transmitted  to the Advisor in writing,  would  prevent or cure any
action described in (a), (b) or (c) above.

         6.  Self-Dealing.  Neither the Advisor nor any Affiliate of the Advisor
shall,  directly or  indirectly,  sell any  property or assets to the Company or
purchase any property or assets from the  Company,  lease any property  from the
Company or borrow any money from the  Company,  except as approved by a majority
of the  Independent  Trustees.  In  addition,  except as  otherwise  provided in
Sections  1,  9 or 10  hereof,  or  except  as  approved  by a  majority  of the
Independent Trustees, neither the Advisor nor any Affiliate of the Advisor shall
receive  any  commission  or other  remuneration,  directly  or  indirectly,  in
connection  with  the  activities  of  the  Company  or  any  joint  venture  or
partnership in which the Company is a party.  The foregoing  prohibitions  shall
not apply to the leases affecting three nursing homes between the Company and an
Affiliate  of the  Advisor,  which  leases were  entered  into by the  Company's
predecessor in interest prior to the date of this Agreement.

         7. No Partnership or Joint Venture. The Company and the Advisor are not
partners  or joint  venturers  with  each  other and  neither  the terms of this
Agreement nor the fact that the Company and the Advisor have joint  interests in
any one or more investments  shall be construed so as to make them such partners
or joint venturers or impose any liability on either of them.

         8.  Fidelity  Bond.  The  Advisor  shall not be  required  to obtain or
maintain a fidelity  bond in  connection  with the  performance  of its services
hereunder.

         9.  Compensation.  The  Advisor  shall  be paid an  advisory  fee  (the
"Advisory Fee") for the services  rendered by it to the Company pursuant to this
Agreement. The Advisory Fee for each full fiscal year of the Company shall equal
the sum of  one-half  of one percent  (0.5%) of the Annual  Average  Transferred
Assets (as defined below), plus seven-tenths of one percent (0.7%) of the Annual
Average Invested Capital (as defined below) up to $250,000,000, plus one-half of
one percent (0.5%) of the Annual Average  Invested Capital equal to or exceeding
$250,000,000.  The Advisory Fee shall be prorated for any partial fiscal year of
the Company during the term of this Agreement. In addition, the Advisor shall be
paid an annual  incentive fee (the "Incentive  Fee") for each fiscal year of the
Company,  commencing  with the Company's  fiscal year ending  December 31, 2000,
consisting  of a number of shares of the  Company's  common shares of beneficial
interest  ("Common  Shares")  with an aggregate  value  (determined  as provided
below) equal to fifteen percent (15%) of the product of (i) the weighted average
Common Shares of the Company outstanding on

                                       -4-
<PAGE>

a diluted  basis  during  such fiscal year and (ii) the excess if any of FFO Per
Share (as  defined  below) for such  fiscal  year over the FFO Per Share for the
preceding  fiscal year;  provided  however,  in no event shall the Incentive Fee
payable in respect of any fiscal  year exceed $.02  multiplied  by the  weighted
average  number of Common  Shares  outstanding  on a diluted  basis  during such
fiscal year.  (The Advisory Fee and Incentive Fee are  hereinafter  collectively
referred to as the "Fees").  No Incentive Fee shall be payable for the Company's
fiscal year ending December 31, 1999.

         For purposes of this Agreement:  "Annual Average Transferred Assets" of
the Company,  for any fiscal year,  means the daily weighted average during such
fiscal year (or, in the case of the  Company's  fiscal year ending  December 31,
1999,  during the period  commencing with the date hereof and ending on December
31,  1999)  of the  aggregate  book  value  of the  Transferred  Assets,  before
depreciation,  reserves for bad debts and other similar  noncash items.  "Annual
Average Invested  Capital" of the Company,  for any fiscal year, means the daily
weighted  average  during such  fiscal  year (or,  in the case of the  Company's
fiscal year ending December 31, 1999, during the period commencing with the date
hereof and  ending on  December  31,  1999) of the  aggregate  book value of the
consolidated assets of the Company,  excluding the Transferred Assets, invested,
directly or indirectly,  in equity interests in and loans secured by real estate
and  personal  property  owned in  connection  with  such  real  estate,  before
depreciation,  reserves for bad debts and other similar noncash items.  "FFO Per
Share," for any fiscal year,  means (i) the Company's  consolidated  net income,
computed in accordance with generally  accepted  accounting  principles,  before
gain or loss on sale of properties and  extraordinary  items,  depreciation  and
other non-cash  items,  including the Company's pro rata share of the funds from
operations  (determined in accordance  with this clause) for such fiscal year of
(A) any  unconsolidated  subsidiary  and (B) any  entity  for which the  Company
accounts  by the  equity  method of  accounting,  divided  by (ii) the  weighted
average  number of Common  Shares  outstanding  on a diluted  basis  during such
fiscal year; and "Transferred  Assets" means the assets owned by the Company and
its subsidiaries on the date hereof. FFO Per Share for the Company's fiscal year
ending December 31, 1999 shall be calculated on a pro forma basis adjusted as if
the transactions  described in the notes to the unaudited pro forma consolidated
financial  statements  of the Company  contained in the  Company's  Registration
Statement No. 333- 69703 filed with the Securities  and Exchange  Commission (as
amended through the date hereof) had occurred as of January 1, 1999.

         The Advisory Fee shall be computed and paid by the Company on a year to
date basis within thirty (30) days following the end of each fiscal month. These
computations  shall be based upon the Company's  monthly or quarterly  financial
statements, as the case may be, and shall be in reasonable detail. The Incentive
Fee shall be computed and paid by the Company  within thirty (30) days following
the public availability of the Company's annual audited financial statements for
each fiscal year. A copy of the computations  shall promptly be delivered to the
Advisor accompanied by payment of the Fees shown thereon to be due and payable.

         The  aggregate  Fees paid for each  fiscal  year  shall be  subject  to
adjustment  as of the end of each that  year.  On or  before  the 30th day after
public  availability of the Company's  annual audited  financial  statements for
each  fiscal  year,  the  Company  shall  deliver to the  Advisor  an  Officer's
Certificate (a "Certificate") reasonably acceptable to the Advisor and certified
by an authorized  officer of the Company  setting  forth (i) the Annual  Average
Transferred Assets, the Annual Average

                                       -5-
<PAGE>

Invested  Capital and FFO Per Share for the Company's fiscal year ended upon the
immediately  preceding  December 31, and (ii) the Company's  computation  of the
Fees payable for the fiscal year.  The  Certificate  shall be  accompanied by an
examination of the  calculation of Annual Average  Invested  Capital and FFO Per
Share by the Company's independent certified public accountants.

         If the  aggregate  Fees  payable  for any  fiscal  year as shown in the
Certificate  exceed the aggregate  amounts  previously paid by the Company,  the
Company  shall pay the  deficit to the  Advisor at the time of  delivery  of the
Certificate.

         If the  aggregate  Fees  payable  for any  fiscal  year as shown in the
Certificate are less than the aggregate amounts  previously paid by the Company,
the Company  shall  specify in the  Certificate  whether the Advisor  should (i)
refund  to the  Company  an amount  equal to the  difference  or (ii)  grant the
Company  a  credit  against  the  Fees  next  coming  due in the  amount  of the
difference until that amount has been fully paid or otherwise discharged.

         Payment  of the  Incentive  Fee  shall be made by  issuance  of  Common
Shares.  The number of shares to be issued in payment of the Incentive Fee shall
be the whole number of shares  (disregarding any fraction) equal to the value of
the Incentive Fee, as provided  above,  divided by the average  closing price of
the Common Shares on the New York Stock Exchange during the month before the end
of the fiscal year for which the computation is made.

         10. Compensation for Additional  Services.  If, and to the extent that,
the  Company  shall  request  the  Advisor to render  services  on behalf of the
Company  other than those  required to be rendered by the Advisor in  accordance
with the terms of this Agreement, those additional services shall be compensated
separately  on terms to be agreed upon  between the Advisor and the Company from
time to time.  In addition,  the Company may make awards to the employees of the
Advisor and others under the Company's  1999  Incentive  Share Award Plan or any
plan adopted by the Company from time to time in replacement thereof.

         11.  Expenses  of the  Advisor.  Without  regard  to  the  compensation
received by the Advisor from the Company pursuant to this Agreement, the Advisor
shall bear the following expenses incurred in connection with the performance of
its duties under this Agreement:

                (a)  employment  expenses  of  the  personnel  employed  by  the
         Advisor,  including but not limited to, salaries,  wages, payroll taxes

         incurred in their capacities as Trustees or officers of the Company;

                (c) rent, telephone,  utilities, office furniture, equipment and
         machinery  (including  computers,  to the  extent  utilized)  and other

         relate solely to an office  maintained by the Company separate from the
         office of the Advisor, if any; and

                                      -6-

                (d)   miscellaneous    administrative   expenses   incurred   in
         supervising,   monitoring  and  inspecting   real  property  and  other
         investments of the Company or relating to performance by the Advisor of
         its obligations hereunder.

         12. Expenses of the Company.  Except as expressly otherwise provided in
this  Agreement,  the  Company  shall pay all its  expenses  not  payable by the
Advisor,  and,  without  limiting  the  generality  of  the  foregoing,   it  is
specifically  agreed that the following expenses of the Company shall be paid by
the Company and shall not be paid by the Advisor:

                  (k)  expenses  relating  to any  office or  office  facilities
         maintained by the Company separate from the office of the Advisor.

         13.  Limits  of  Advisor   Responsibility.   The  Advisor   assumes  no
responsibility  other than to render the services described herein in good faith
and shall not be  responsible  for any action of the  Trustees in  following  or
declining to follow any advice or  recommendation  of the Advisor.  The Advisor,
its shareholders, directors, officers, employees, agents and Affiliates will not
be liable to the Company, its shareholders,  or others, except by reason of acts
constituting bad faith,  willful or wanton misconduct or gross  negligence.  The
Company  shall  reimburse,   indemnify  and  hold  harmless  the  Advisor,   its
shareholders,  directors,  officers and employees, agents and Affiliates for and
from any and all expenses,  losses, damages,  liabilities,  demands, charges and
claims of any  nature  whatsoever  in  respect  of or  arising  from any acts or
omissions of the Advisor  undertaken  in good faith and in  accordance  with the
standard  set  forth  above  pursuant  to the  authority  granted  to it by this
Agreement.

         14.  Other  Activities  of the  Advisor and its  Stockholders.  Nothing
herein shall prevent the Advisor from engaging in other activities or businesses
or from  acting as  advisor to any other  Person  (including  other real  estate
investment  trusts)  even  though  that  Person  has  investment   policies  and
objectives similar to those of the Company; provided,  however, that neither the
Advisor nor Barry M. Portnoy or Gerard M. Martin shall provide advisory services
to, make competitive direct investment in or, in the case of Messrs. Portnoy and
Martin,  serve as a director  or officer  of, any other real  estate  investment
trust  which is  principally  engaged in the  business  of  ownership  of senior
apartments,  congregate communities,  assisted living or nursing home properties
without the consent of a majority of the Independent Trustees. The Advisor shall
be free from any obligation to present to the Company any particular  investment
opportunity  which  comes to the  Advisor.  In  addition,  except  as  expressly
provided  herein,  nothing herein shall prevent any  stockholder or Affiliate of
the Advisor from engaging in any other  business or from  rendering  services of
any  kind to any  other  corporation,  partnership  or other  entity  (including
competitive business activities). Without limiting the foregoing provisions, the
Advisor  agrees,  upon the  request of any Trustee of the  Company,  to disclose
certain  investment  information  concerning  the  Advisor  or  certain  of  its
Affiliates,  provided, however, that the disclosure shall be required only if it
does not constitute a breach of any fiduciary duty or obligation of Advisor.

         Directors,  officers,  employees  and  agents of the  Advisor or of its
Affiliates  may serve as  Trustees,  officers,  employees,  agents,  nominees or
signatories  of the Company.  When  executing  documents or otherwise  acting in
capacities for the Company,  these persons shall use their respective  titles in
the Company.

         15.  Term,  Termination.  This  Agreement  shall  continue in force and
effect  until  December  31,  1999  (the  "Initial  Term"),   and  is  renewable
periodically  thereafter  by the  Company,  if a  majority  of  the  Independent
Trustees determine that the Advisor's performance has been satisfactory.

         Paragraph  18  hereof  shall   govern  the  rights,   liabilities   and
obligations of the parties upon  termination of this  Agreement;  and, except as
provided in paragraph 18, a termination  shall be without  further  liability of
either party to the other than for breach or violation of this  Agreement  prior
to termination.

         16. Assignment. The Company may terminate this Agreement at any time in
the  event  of  its  assignment  by  the  Advisor  except  an  assignment  to  a
corporation,  partnership,  trust or other successor  entity which may take over
the property and carry on the affairs of the Advisor; provided that, following a
permitted  assignment,  the persons who controlled the operations of the Advisor
immediately  prior  to  the  assignment  shall  control  the  operation  of  the
successor,  including the  performance of its duties under this  Agreement,  and
this successor shall be bound by the same  restrictions by which the Advisor was
bound prior to such assignment.  A permitted  assignment or any other assignment
of this  Agreement by the Advisor shall bind the assignee  hereunder in the same
manner as the Advisor is bound hereunder. This Agreement shall not be assignable
by the Company without the prior written  consent of the Advisor,  except in the
case of any  assignment by the Company to a trust,  corporation,  partnership or
other entity which is the successor to the Company,  in which case the successor
shall be bound hereby and by the terms of said assignment in the same manner and
to the same extent as the Company is bound hereby.

         17. Default, Bankruptcy, Etc. of the Advisor. At the sole option of the
Company, this Agreement may be terminated immediately by written notice from the
Trustees to the Advisor if any of the following events shall have occurred:

                (a) the  Advisor  shall  have  violated  any  provision  of this
         Agreement and, after written notice from the Trustees of the violation,
         shall have failed to cure the default within thirty (30) days;

                (b) a petition  shall have been filed against the Advisor for an
         involuntary proceeding under any applicable  bankruptcy,  insolvency or
         other similar law now or hereafter in effect,  and that petition  shall
         not have been dismissed  within ninety (90) days of filing;  or a court
         having  jurisdiction  shall  have  appointed  a  receiver,  liquidator,
         assignee,  custodian,  trustee, sequestrator or similar official of the
         Advisor for any  substantial  portion of its  property,  or ordered the
         winding up or liquidation of its affairs, and that appointment or order
         shall not have been rescinded or vacated within ninety (90) days of the
         appointment or order; or

                (c) the Advisor  shall have  commenced  a  voluntary  proceeding
         under any applicable bankruptcy, insolvency or other similar law now or
         hereafter in effect, or shall have made any general  assignment for the
         benefit of creditors,  or shall have failed  generally to pay its debts
         as they became due.

                                       -9-
<PAGE>

         The Advisor  agrees that, if any of the events  specified in paragraphs
(b) or (c) of this Section 17 occur,  it will give written notice thereof to the
Trustees within seven (7) days following the occurrence of the event.

         18. Action Upon  Termination.  From and after the effective date of any
termination  of this  Agreement  pursuant to Sections  15, 16 or 17 hereof,  the
Advisor shall be entitled to no compensation for services rendered hereunder for
the remainder of the then-current term of this Agreement but shall be paid, on a
pro  rata  basis,  all   compensation  due  for  services   performed  prior  to
termination,  including,  without  limitation,  a pro rata  portion  of the then
current year's Incentive Fee. Upon termination, the Advisor immediately shall:

                  (a) pay over to the Company all monies  collected and held for
         the  account of the Company by it  pursuant  to this  Agreement,  after
         deducting  therefrom  any accrued and unpaid Fees  (including,  without
         limitation,  a pro rata  portion of the then current  year's  Incentive
         Fee, and reimbursements for its expenses to which it is then entitled);

                  (b) deliver to the  Trustees a full and  complete  accounting,
         including a statement  showing all sums collected by it and a statement
         of all  sums  held  by it for  the  period  commencing  with  the  date
         following the date of its last accounting to the Trustees; and

                  (c) deliver to the Trustees all property and  documents of the
         Company then in its custody or possession.

         The  amount  of Fees  paid to the  Advisor  upon  termination  shall be
subject to adjustment pursuant to the following mechanism. On or before the 30th
day  after  public  availability  of  the  Company's  annual  audited  financial
statements for the fiscal year in which  termination  occurs,  the Company shall
deliver to the Advisor a  Certificate  reasonably  acceptable to the Advisor and
certified by an authorized  officer of the Company  setting forth (i) the Annual
Average  Transferred  Assets,  the Annual Average  Invested  Capital and FFO Per
Share  for the  Company's  fiscal  year  ended  upon the  immediately  preceding
December 31, and (ii) the Company's computation of the Fees (including,  without
limitation, a pro rata portion of the then current year's Incentive Fee) payable
upon the date of termination.  The Certificate  shall be accompanied by a review
of the calculation of the Annual Average  Transferred Assets, the Annual Average
Invested Capital and FFO Per Share by the Company's independent certified public
accountants.

         If the annual Fees owed upon  termination  as shown in the  Certificate
exceed the Fees paid by the Company upon termination,  the Company shall include
its  check  for the  deficit  and  deliver  the  same to the  Advisor  with  the
Certificate.

         The  Incentive  Fee for any partial  fiscal year will be  determined by
multiplying  the Incentive Fee for such year  (assuming  this  Agreement were in
effect for the entire year) by a fraction,  the numerator of which is the number
of days in the portion of such year during which this  Agreement  was in effect,
and the denominator of which shall be 365.

                                      -10-
<PAGE>

         If the annual Fees owed upon  termination  as shown in the  Certificate
are less than the Fees paid by the Company upon  termination,  the Advisor shall
remit to the Company its check in an amount equal to the difference.

         19.  Trustee  Action.  Wherever  action on the part of the  Trustees is
contemplated by this Agreement, action by a majority of the Trustees,  including
a majority of the Independent Trustees, shall constitute the action provided for
herein.

         20.  Arbitration.  The Company  and the Advisor  agree that any and all
disputes and disagreements  arising out of or relating to this Agreement,  other
than  actions or claims  for  injunctive  relief or claims  raised in actions or
proceedings brought by third parties, shall be resolved through negotiations or,
if the dispute is not so  resolved,  through  binding  arbitration  conducted in
Boston,  Massachusetts under the  J.A.M.S./Endispute  Comprehensive  Arbitration
Rules and Procedures,  with the following  amendments to those rules. First, the
parties  agree  that in no event  shall the  arbitration  from  commencement  to
issuance of an award take longer than 180 days.  Second,  the parties agree that
the arbitration tribunal shall consist of three arbitrators and that the parties
elect not to have the optional appeal procedure  provided for in Rule 23. Third,
in lieu of the  depositions  permitted in Rule 15(E) and (F), the parties  agree
that the only  depositions  shall be a single  deposition to last no longer than
one six-hour day that each party may take of the opposing party or an individual
under the control of the opposing  party.  Judgment on the award rendered by the
arbitrators may be entered in any court having jurisdiction thereof.

         21. TRUSTEES AND SHAREHOLDERS  NOT LIABLE.  THE DECLARATION OF TRUST OF
