PROSPECTUS
                                11,000,000 Shares
                         Senior Housing Properties Trust
                      Common Shares of Beneficial Interest

                           ---------------------------


     Senior Housing  Properties Trust is a real estate  investment  trust.  Upon
completion of this  offering,  we will own or have  commitments to buy 98 senior
housing,  congregate communities,  assisted living properties and nursing homes,
with 13,750 units/beds that are leased to nine unaffiliated tenants.

   
     This is Senior Housing Properties Trust's initial public offering of common
shares.  Prior to this  offering  no public  market  for the  common  shares has
existed. We intend to make regular quarterly distributions initially at the rate
of $.40 per  share  ($1.60  per share on an annual  basis)  commencing  with the
quarter ending March 31, 1999. We expect the public offering price to be between
$18.00 and $20.00 per common share.  After  pricing of the  offering,  we expect
that the  common  shares  will trade on the New York  Stock  Exchange  under the
symbol "__."
    

     We are simultaneously offering 350,000 common shares in a separate offering
to our Managing  Trustees.  The Managing  Trustees will pay the public  offering
price per share set forth  below.  No  underwriting  discount  will be paid with
respect to these shares, and we will receive 100% of the proceeds.

   
     Investing in the common  shares  involves  risks which are described in the
"Risk Factors" section beginning on page 12 of this prospectus, including:

     o    A  majority  of  our  income  will  come  from  one  tenant,  Marriott
          International, Inc.
     o    Some of our tenants may experience  problems  beyond our control which
          impair   their   abilities  to  pay  rent  and  our  ability  to  make
          distributions.
     o    Some of our properties are subject to burdensome regulations.
     o    Some of the  properties  we  expect to buy from  Marriott  are not yet
          fully built.
     o    Our ability to grow will depend upon our future  access to capital and
          future  efforts  by our  investment  advisor,  Managing  Trustees  and
          officers.
     o    Affiliates  will  own  36% of our  shares,  their  interests  may  not
          coincide with the interest of other shareholders, and these affiliates
          will receive substantial benefits from this offering.

                           FORWARD LOOKING STATEMENTS

     This prospectus  contains forward looking  statements.  We have based these
statements on our current expectations about future events and on assumptions we
have  made.   These  forward  looking   statements  are  subject  to  risks  and
uncertainties  which could cause actual  results or events to differ  materially
from those we project. Prospective purchasers should not place undue reliance on
these forward looking statements. We undertake no obligation to update or revise
any forward looking statements as a result of new information,  future events or
otherwise.

                           ---------------------------


     You should rely only on the information  contained in this  prospectus.  We
have not, and the  underwriters  have not,  authorized any person to provide you
with  different   information.   If  anyone   provides  you  with  different  or
inconsistent  information,  you  should  not  rely on it.  We are  not,  and the
underwriters  are  not,  making  an  offer  to  sell  these  securities  in  any
jurisdiction  where the offer or sale is not  permitted.  You should assume that
our business,  financial condition, results of operations and prospects may have

     The  Declaration of Trust  establishing  Senior Housing  Properties  Trust,
dated December 16, 1998, a copy of which,  together with all amendments thereto,
is filed in the office of the  Department  of  Assessments  and  Taxation of the
State of Maryland,  provides  that the name "Senior  Housing  Properties  Trust"
refers to the  trustees  under the  Declaration  of Trust as  trustees,  but not
individually  or  personally.  The  Declaration  of Trust also  provides that no
trustee,  officer,  shareholder,  employee or agent of Senior Housing Properties
Trust shall be held to any personal  liability for any  obligation  of, or claim
against,  Senior  Housing  Properties  Trust.  All persons  dealing  with Senior
Housing  Properties  Trust  shall  look only to the  assets  of  Senior  Housing
Properties  Trust  for  the  payment  of  any  sum  or  the  performance  of any
obligation.

                           ---------------------------


     In this prospectus we assume that the 84 properties  currently owned by HRP
have been  transferred  to us and that a binding  agreement has been signed with
respect to the 14 new Marriott properties to be acquired that is consistent with
the letter of intent  presently  in effect.  These  events are expected to occur
before this offering commences.  Similarly,  the descriptions of the Declaration
of Trust, By-laws, management and common shares contained in this prospectus are
presented  giving  effect to various  changes that will occur before the sale of
our common shares.  All references to owned  properties  include  investments in
mortgages on properties for which we have nominal price purchase options.

                                   THE COMPANY

     Senior Housing Properties Trust (the "Company") is a real estate investment
trust  ("REIT")  formed to acquire  and own senior  living  properties  that are
leased  to  unaffiliated   tenants,   including   senior   housing,   congregate
communities,  assisted living  properties and nursing homes. We currently own 84
properties  including 14 leased to Marriott  International,  Inc. (including its
subsidiaries,  "Marriott").  We will use the  proceeds  from  this  offering  to
purchase  14  additional  assisted  living  properties  which  we will  lease to
subsidiaries of Marriott. If we do not acquire all of these Marriott properties,
we intend to use the proceeds  for working  capital and other  general  business
purposes including other acquisitions. This offering is not conditioned upon the
acquisition of any particular properties.

Growth Strategy

     The population of the United States is aging. During the past 35 years, the
increasing  percentage of women working away from their homes,  the high divorce
rate and societal mobility have all combined to make traditional arrangements of
family care for aging relatives less  available.  Although there are benefits to
home healthcare,  it is generally more economically  efficient to congregate the
elderly in properties with specialized  services than to bring those services to
diverse locations. Similarly, the cost containment pressure to reduce lengths of
stay  for the  elderly  in high  cost  hospitals  has  increased  the  need  for
intermediate care properties. We believe this combination of demographic, social
and economic  factors will increase the demand for  specialized  senior  housing
properties and nursing homes for the foreseeable future.

     Our  business  plan is to profit from this  increasing  demand in two ways.
First, we intend to purchase additional  properties and lease them at rents that
are  greater  than our  costs of  acquisition  capital.  Second,  we  intend  to
structure leases that have periodic rental increases.  We expect that our future
investments will focus upon properties  similar to the new Marriott  properties.
We expect these newer properties to attract residents who use private resources,
rather than government programs, to pay for rent and services.

History and Management

   
     We are presently a 100% owned  subsidiary of HRPT Properties  Trust, a NYSE
listed REIT ("HRP").  All 84  properties  that we own were acquired by HRP since
1987.  Our  operations  will  be  conducted  by  our  investment  advisor,  REIT
Management & Research,  Inc.  ("RMR").  RMR is owned by our  Managing  Trustees,
Barry M.  Portnoy  and Gerard M.  Martin.  RMR has  approximately  180 full time
employees,  and its principals and other  personnel have  experience in managing
REITs to produce  increasing  distributions  and have extensive  contacts in the
senior housing and healthcare industries.

     Our management team founded HRP in 1986 with $63 million  invested in seven
healthcare  properties  leased to two tenants.  Today, HRP has  approximately $3
billion invested in 255 properties  leased to over 500 tenants.  As HRP grew, it
diversified  its  investments  to include  hotels,  office  buildings and senior
housing properties in addition to its original healthcare facilities. During its
12 years in business,  HRP has made 48 consecutive  quarterly  distributions and
raised its distribution rate 13 times.

     In 1995 our  management  team  founded a new REIT,  Hospitality  Properties
Trust ("HPT"), to capitalize separately and grow HRP's hotel investments. At its
initial  public  offering  in 1995 HPT had $329  million  invested  in 37 hotels
leased to one tenant.  Today, HPT has almost $1.8 billion invested in 167 hotels
leased to nine tenants. During its three and one half years in business, HPT has
made 14 consecutive  quarterly  distributions  and raised its distribution  rate
nine times.
    

     A primary purpose of this offering is to capitalize  separately our Company
as a new REIT with a strong  core of senior  housing  real  estate and  industry
contacts to take advantage of favorable market  conditions.  To facilitate these
efforts two senior officers of RMR will be assigned to devote  substantially all
of their  business  time to our  Company.  David J.  Hegarty  is  currently  the
President  and  Chief  Operating  Officer  of both  RMR and HRP.  Ajay  Saini is
currently a Vice President of RMR and Treasurer and Chief  Financial  Officer of
HRP. Upon  completion of this  offering,  Messrs.  Hegarty and Saini will resign
their  positions at HRP and assume similar  positions at our Company.  All other
RMR personnel including our Managing Trustees,  Messrs. Portnoy and Martin, will
devote a significant part of their time to assist in this effort.

     Upon the completion of this offering, HRP will distribute 13,187,380 of our
common shares to its  shareholders on the basis of one common share for every 10
HRP shares owned on _______,  1999.  HRP will retain  13,187,380  common  shares
after  this  distribution.  Simultaneously  with  this  offering,  our  Managing
Trustees  will purchase  350,000  common shares at the same price paid by public
investors. After completion of this offering, our Managing Trustees will own 1%,
HRP will own 35% and the public generally (including public shareholders of HRP)
will own 64% of our Company.

Competition

     There are several  publicly owned REITs that today invest in senior housing
and healthcare real estate.  Also, some asset based finance  companies and banks
have  marketing  programs to provide sale  leaseback and mortgage  financing for
these types of  properties.  Some of these  competitors  have resources that are
greater  than we will have and some have a cost of capital that may be less than
we will  have.  Nonetheless,  we  believe  that we will be able to  successfully
compete for new investments for at least five reasons:

     First,  our  initial  senior  living   properties  have  solid  records  of
performance. We will commence business with a large and diversified portfolio of
properties which have strong prospects based on demographic trends and which are
subject to long term leases.

     Second,  we will be the only REIT  exclusively  focused  on  senior  living
properties. We do not intend to invest in medical office buildings, hospitals or
any  properties  which do not benefit from the  projected  aging of the American
population.

                                        6
<PAGE>
     Third,  current market  conditions  have created an  opportunity  for a new
market entrant to purchase and lease senior living properties. A large number of
recently developed  properties are currently  available.  The current turmoil in
the mortgage markets has limited capital for new development and has reduced the
financing  available to several of our competitors.  A new Medicare  prospective
payment  program has caused nursing homes to be revalued so that purchase prices
and rents can be set at levels which are well  covered by current and  projected
property operations.

     Fourth,  our  proposed  methods  of  doing  business  are  intended  to  be
attractive to a diversified  group of prospective  sellers and tenants of senior
living properties.  We intend to do business only with unaffiliated  sellers and
tenants and to retain the financial flexibility to work with our tenants to meet
their business requirements.

     Finally,  and perhaps most  importantly,  our management team has extensive
experience  and  contacts  in the senior  housing  and  healthcare  real  estate
markets.

Properties

     After  completion  of our purchase and lease of the 14 new assisted  living
properties from Marriott,  56% of our rent will come from  properties  leased to
Marriott and 94% of our rent will come from property  leases which are committed
until December 31, 2010. The following  table  summarizes the tenants,  types of
properties and important lease terms for our properties:

Distributions

     We intend to make distributions on a quarterly basis. We expect the initial
quarterly  distribution  rate to be $.40 per share ($1.60 per share on an annual
basis). We will make our initial  distribution  shortly after the quarter ending
March 31, 1999 in the  anticipated  amount of $__ per share (the pro rata amount
from the date of the offering through March 31, 1999). We intend to periodically
increase our  distributions  as our cash flow  increases.  Of course,  we cannot
guarantee  that  our  cash  flow  will  always  permit  us to make  or  increase
distributions.
    

Company's Address

     Our principal  place of business is located at 400 Centre  Street,  Newton,
Massachusetts 02458, and our telephone number is (617) 796-8350.

                                  RISK FACTORS

   
     An investment  in our common  shares  involves  various  risks.  You should
carefully consider the information contained in "Risk Factors" beginning on page
12 prior to investing. The following discussion summarizes some of these risks.
    

     o    Dependence  Upon Marriott.  Marriott is our largest  tenant.  After we
          purchase and lease the 14 new Marriott  properties,  Marriott  will be
          the source of 56% of our rents.  Changes  could occur at Marriott that
          are beyond our control and may  jeopardize  Marriott's  ability to pay
          our rent.

   
     o    Dependence  Upon  Tenants.  Some  or all of our  tenants  could  incur
          operating or financial  problems that jeopardize  their ability to pay
          rents.  If we  cannot  collect  our  rents,  we may be  unable  to pay
          distributions.
    
     o    Real Estate Risks. The real estate business is generally considered to
          be cyclical and subject to periodic  oversupply.  Our business will be
          subject to  various  risks  customarily  associated  with real  estate
          ownership and acquisitions, including environmental risks.

     o    Healthcare  Properties Risks. Certain healthcare properties are highly
          regulated.  A large  percentage of the revenues at certain  healthcare
          properties  are  paid by  government  programs  such as  Medicare  and
          Medicaid.  Changes in these  regulations or in the amounts of payments
          available  under  Medicare  and  Medicaid  programs  may  restrict our
          tenants' abilities to pay rent.

     o    Completion of New Marriott  Properties.  Construction of ___ of the 14
          properties  to be acquired  from  Marriott  with the  proceeds of this
          offering has not been completed.  Because  Marriott is responsible for
          this construction, we can provide no assurances that this construction
          will be completed in a timely manner or at all.

     o    Possible Failure of Growth Strategy.  Our growth strategy depends,  in
          part,  upon our ability to raise  additional  capital and to invest in
          new  properties  which  will  produce  rents in excess of our costs of
          capital. We can provide no assurance that capital will be available at
          reasonable  costs  or that we will  be  able  to  purchase  and  lease
          additional properties.

     o    Limited Operating  History and Dependence Upon Key Personnel.  We have
          not previously  operated  independently.  Our success depends upon the
          efforts of our investment advisor, Managing Trustees and officers.

                                        8
<PAGE>

     o    Concentration of Ownership.  Upon completion of this offering HRP will
          own 35% of our outstanding  common shares.  This ownership will enable
          HRP to have a significant influence over shareholder decisions.

     o    Conflicts of  Interest.  Barry M. Portnoy and Gerard M. Martin are the
          Managing  Trustees of our Company and HRP and also own the  investment
          advisor to our  Company  and HRP.  The  interests  of HRP,  of Messrs.
          Portnoy  and  Martin and of our  investment  advisor  may,  in certain
          circumstances,   conflict  with  the  best   interests  of  our  other
          shareholders.

     o    Benefits to Related  Parties.  The  completion  of this  offering will
          result in substantial  benefits to related parties. For example, 14 of
          our properties will be mortgaged for $250 million, and we will use the
          proceeds to repay a loan from HRP.

     o    Lack of Prior  Market for the Common  Shares.  The market value of our
          common  shares may decline if an active  market does not develop after
          this offering.

   
     o    Possible  Future Sales of Common  Shares.  We may  authorize and issue
          additional common shares without  shareholder  approval.  In addition,
          the HRP  shareholders  receiving our common  shares as a  distribution
          from HRP will be free to sell their  shares.  An  oversupply of shares
          available  for sale could  adversely  affect  the market  price of our
          common shares.

     o    Tax Risks. If we fail to meet complex REIT qualification requirements,
          we will be subject to corporate  taxes and the money available to make
          distributions will be reduced.

     o    Risks of Debt  Leverage.  If we incur  excessive debt or are unable to
          refinance debt before its maturity,  our ability to make distributions
          may  be  jeopardized.   A  default  on  secured  debt  may  result  in
          foreclosure on our mortgaged properties.
    
     o    Ownership Limitations and Anti-Takeover  Provisions.  Shareholders are
          prohibited from owning more than 9.8% of our Company.  Our Declaration
          of Trust and our By-laws  contain other  provisions that may inhibit a
          change of control.  Because of these  limitations our shareholders may
          be unable to  realize a change of  control  premium  for their  common
          shares.

     o    Policy  Changes.  Our Board of Trustees may change our  investment and
          business policies without shareholder approval.

     o    Properties Subject to Ground Leases. Two of our properties are on land
          that is leased  rather  than owned.  Our tenants  must pay rents under
          these  ground  leases  as well as our rent.  If a tenant  fails to pay
          ground rent,  we may have to do so to protect our  investment in these
          properties.

     o    Dilution.  The book value per  common  share of our net assets is less
          than the expected sale price of our common  shares.  Accordingly,  you
          will experience immediate dilution in the book value per common share.

         SUMMARY HISTORICAL AND ADJUSTED PRO FORMA FINANCIAL INFORMATION

   
   The following  table  presents  historical  and adjusted pro forma  financial
information  and other data for our  properties.  We are  currently a 100% owned
subsidiary  of HRP, and none of our  properties  are  encumbered  by debt. It is
impossible  to  estimate  all  operating  expenses  we would have  incurred as a
separate  public company.  The following table includes pro rata  allocations of
interest expense and certain general and administrative  expenses for historical
periods.  However,  the net  income  and  funds  from  operations  shown are not
necessarily  indicative  of results that we will realize as a separate  company.
The adjusted pro forma information  assumes that this offering is completed at a
public  offering price of $19 per common share and that net proceeds are used to
purchase  and lease 14 new Marriott  properties  and  includes  adjustments  for
certain  properties  under  development.  For additional  information  about the
calculation  of  amounts  appearing  in this table see the  Unaudited  Pro Forma
Financial Statements and notes thereto included elsewhere in this prospectus.

                                  RISK FACTORS

     Before  deciding to purchase  common  shares,  you should  consider all the
information contained in this prospectus, including the following risk factors:

Dependence Upon Marriott

     Marriott is our largest  tenant and will be the source of 56% of our rents.
Marriott has unconditionally guaranteed the lease obligations with regard to the
14  properties  that we now own.  With  regard  to the 14 new  properties  to be
purchased and leased, Marriott's guaranty will expire at year-end 2006 or sooner
if certain  financial  performance  thresholds at these properties are achieved.
Today  Marriott  appears  to be  financially  able to meet  all of its  rent and
guaranty obligations.  However,  changes could occur at Marriott that are beyond
our control and may jeopardize Marriott's ability to pay our rent.

Dependence Upon Tenants

   
     Our success  depends upon our ability to collect rent. If we cannot collect
our rents, we may be unable to make  distributions  or to meet our expenses.  We
lease most of our current  properties to affiliates of publicly owned  companies
that appear to be well capitalized.  However, some or all of these tenants could
incur operating or financial  problems that may jeopardize  their ability to pay
rent. Also, we may make future investments in properties that are leased to less
creditworthy tenants.
    

Real Estate Risks

     The real estate business is generally considered to be cyclical and subject
to periodic oversupply. In some states,  regulations that limit new construction
of certain  healthcare  properties  protect those  properties  from some of this
cyclicality.  However, the financial  performance of senior living properties is
generally subject to real estate business cycles.

     Our  business  will be subject to all of the risks  customarily  associated
with real estate acquisitions and ownership,  including casualty loss risks, the
risks of lease  renewals,  the risks of lease defaults and the risk that we will
not have capital available to fund regular capital expenditures, among others.

     Various  environmental  laws impose liability on current or previous owners
or operators of real  property  for the costs of  investigation  and clean-up of
hazardous or toxic substances on or migrating from their properties.  These laws
often  impose  liability  regardless  of the  knowledge or fault of the owner or
operator  if a  hazardous  or  toxic  substance  is found  on a  property.  This
liability  may also be joint and  several,  meaning that one party may be liable
for the entire cost of clean-up  even though  other  parties may also be liable.
Persons who arrange for the disposal or treatment  of hazardous  substances  may
also be liable for the costs of  clean-up  of  contamination  at a  disposal  or
treatment  facility.   Also,   environmental  laws  impose   responsibility  for
properties  with asbestos  containing  materials  which are in poor condition or
when the properties are undergoing renovation. Owners of contaminated properties
may be liable for damages or injuries  caused by the  contamination.  A property
owner may be  responsible  for the costs of removing  underground  storage tanks
found on its property.  Besides  these  potential  liabilities,  the presence of
hazardous  substances may adversely affect the market value of the property,  as
well as the owner's ability to sell, lease or finance the property.

     HRP owned all of our current  properties  before their  transfer to us. HRP
has  represented  to us that  it does  not  know of any  material  environmental
problems that exist on these properties. Also, under each of our current leases,
the tenants are responsible for any environmental clean-up that may be necessary
and must  indemnify  us for any costs or  liability  we incur  with  respect  to
environmental matters.

                                       12
<PAGE>

Accordingly,  we do not  intend  to obtain  new  environmental  site  assessment
reports for our initial properties. We do intend to obtain Phase I environmental
site  assessment  reports  on  the  new  Marriott   properties.   The  state  of
environmental  laws is such that we can  provide  no  assurance  that any of the
environmental  indemnification provisions in the existing leases are enforceable
or  that  we  will  have  no   liability   even  if  we  are  entitled  to  some
indemnification.  Also,  if  any  of  our  tenants  has  responsibility  for  an
environmental  clean-up,  that  liability  could  adversely  affect the tenant's
ability to pay our rent.

Healthcare Properties Risks

     Our investing in healthcare properties involves certain risks:

     o   Various governmental authorities regulate healthcare properties.  These
         regulations  can change.  Sometimes these changes require major capital
         expenditures.  We believe  that our  current  properties  substantially
         comply with all applicable regulations. However, our properties must be
         regularly  maintained to remain in regulatory  compliance.  Because our
         properties  are  triple  net  leased to  tenants  we have only  limited
         control over the maintenance of our properties.

     o   Governmental  programs  such  as  Medicare  and  Medicaid  pay a  large
         percentage  of the  charges  for  occupancy  and  services  at  certain
         healthcare  properties.  We believe the current  rates  received by our
         tenants at our properties are adequate to permit our tenants to pay our
         rent.  However,  there are various  legislative  proposals to limit the
         growth of government  expenditures  for healthcare;  if enacted,  these
         proposals may impair our tenants' abilities to pay rent.

     o   Certain of our  properties  were  specifically  designed for healthcare
         operations.  If these  properties  cannot  be  operated  as  healthcare
         facilities,  finding an  alternative  use for these  properties  may be
         difficult and costly.

Completion of New Marriott Properties

     Marriott has not yet completed  construction  of of the 14 assisted  living
properties to be acquired with the proceeds of this offering.  Because  Marriott
is responsible  for this  construction,  we can provide no assurances  that this
construction  will be completed in a timely  manner or at all. If some or all of
these  properties  are  not  completed,  we will  have a  smaller  portfolio  of
properties  than  anticipated,  and our  initial  cash  flow  may be  less  than
expected.  This  offering  is  not  conditioned  upon  the  acquisition  of  any
particular  properties.  If we do not use some or all of the proceeds  from this
offering to acquire  these  Marriott  properties,  we will use the  proceeds for
general  business  purposes,  including  future  acquisitions.  However,  we can
provide  no  assurance  that we will be able to  purchase  and lease  substitute
properties.

Possible Failure of Growth Strategy

     Our growth  strategy  requires  that we raise  additional  capital and then
invest  in new  properties  that  will  produce  rents in excess of our costs of
capital.  Our ability to raise debt and equity capital in the future will depend
not only upon our performance but also upon capital market  conditions which are
beyond our control.  Our management has extensive  experience in raising capital
and in  purchasing  and leasing real estate.  However,  there are several  other
REITs as well as  other  finance  companies  that now  aggressively  compete  to
purchase  and lease senior  living  properties.  Accordingly,  we can provide no
assurance that our growth strategy will succeed.


                                       13
<PAGE>
Limited Operating History and Dependence Upon Key Personnel

     We are  currently a 100% owned  subsidiary  of HRP and have not  previously
operated  independently.  Our success depends upon the efforts of our investment
advisor,  Managing  Trustees  and  officers  who  have all  previously  operated
publicly  owned  REITs  and  managed  entities   investing  in  senior  housing,
congregate   communities,   assisted   living   properties  and  nursing  homes.
Nonetheless,  every new venture carries with it certain risks. For example,  our
company will be smaller than other REITs operated by our investment  advisor and
smaller than some of our competitors. Similarly, the lack of a track record as a
separate company may restrict our ability to raise capital. Our business will be
subject to these and all other risks generally associated with the formation and
conduct of a new business.

Concentration of Ownership

     Upon completion of this offering HRP will own 35% of our outstanding common
shares.  Accordingly,  HRP will have a significant  influence  over  shareholder
decisions.  Such  influence may result in decisions  that may not serve the best
interests of our other shareholders.

Conflicts of Interest

     Conflicts of interest may arise in our business, including the following:

     o   Barry M. Portnoy and Gerard M. Martin,  who are our Managing  Trustees,
         also  own  our  investment  advisor,  RMR.  RMR has  approximately  180
         employees   and  has  extensive   experience   acquiring  and  managing
         properties  for  publicly  owned  REITs.  We believe  that the depth of
         management  talent  available to us through our advisory  contract with
         RMR will provide us a  competitive  advantage and that the fees payable
         to RMR are commercially reasonable.  Nonetheless,  we did not negotiate
         the  advisory  agreement  at arms' length with RMR and the advisory fee
         will increase by investments we make.

     o   In addition to serving as our Managing  Trustees,  Messrs.  Portnoy and
         Martin are managing  trustees of HRP and HPT.  They also have  business
         interests separate from these other REITs.  Similarly,  RMR acts as the
         investment  advisor  to HRP and HPT and has other  business  interests.
         These various business activities will compete for management time.

     o   Upon completion of this offering, HRP will own approximately 35% of our
         outstanding   common  shares  and  have  considerable   influence  over
         shareholder  actions.  Messrs.  Portnoy  and  Martin  are our  Managing
         Trustees   and  the  managing   trustees  of  HRP.   Because  of  these
         relationships, the interests of HRP and Messrs. Portnoy and Martin may,
         in certain circumstances, conflict with our best interests.

     To address the foregoing  and other  potential  conflicts of interest,  our
Declaration of Trust provides that Independent  Trustees who have no affiliation
with the Managing Trustees,  RMR or HRP (so long as HRP remains a shareholder of
ours) must  constitute  a majority  of the Board of  Trustees  at all times.  To
address the competing  time  demands,  RMR intends that Mr. David  Hegarty,  our
President and Chief  Operating  Officer,  and Mr. Ajay Saini,  our Treasurer and
Chief Financial Officer,  will devote substantial amounts of their business time
to our Company. In addition, pursuant to the advisory agreement, RMR and Messrs.
Portnoy and Martin have agreed not to provide advisory  services to, or serve as
directors  or officers  of, any other REIT that  invests  principally  in senior
housing, congregate communities,  assisted living properties or nursing homes or
to make competitive direct investments in similar  properties  without,  in each
case,  the  consent of the  Independent  Trustees.  To promote  an  identity  of
economic  interest between  management and  shareholders,  our Managing Trustees
will purchase 350,000 shares at

                                       14
<PAGE>

the same price paid by public  investors  in this  offering and the advisory fee
will be paid in part in our common shares.  Moreover,  the  continuation  of the
Advisory  Agreement  and the fees  payable to RMR will be  subject  to  periodic
review by our Independent Trustees.

Benefits to Related Parties

     The  completion  of this offering  will result in  substantial  benefits to
related parties, including the following:

     o   The 14 Marriott  properties that we currently own will be mortgaged for
         $250  million   immediately  after  we  complete  this  initial  public
         offering.  The  mortgage  proceeds  will be paid to HRP to satisfy  the
         intercompany  debt created as part of our  formation  transaction.  HRP
         will  not be  liable  for  this  mortgage  debt.  Instead,  we  will be
         responsible to repay this debt.

     o   HRP is  currently  contractually  bound to purchase the 14 new Marriott
         properties for $193.8 million. Upon completion of this offering we will
         assume this HRP obligation.

     o   Upon  completion  of this  offering  RMR  will  become  our  investment
         advisor.  Assuming  that we had owned all 98 properties to be initially
         owned  (including  the 14 properties  to be purchased  with proceeds of
         this offering) for a full year, the annual  advisory fee payable to RMR
         would have been $4.6 million. HRP's annual advisory fees to RMR will be
         reduced by approximately the same amount.

     o   Our  Managing  Trustees  will  purchase  350,000 of our  common  shares
         simultaneously with the completion of this offering.  They will pay the
         same  price per share as public  investors  pay in this  offering.  Our
         Managing Trustees have agreed not to sell these shares for at least one
         year. By purchasing a large block of shares  directly from the Company,
         our  Managing  Trustees  are able to avoid the risk that this  purchase
         might affect the market price of our common shares.

   
     o   Upon  completion  of this  offering,  13.2 million of our common shares
         will  be   distributed  to  HRP   shareholders.   We  will  receive  no
         consideration for this distribution.

     o   After this offering HRP will retain 13.2 million of our common  shares.
         By  retaining  these  shares,  HRP will be able to  participate  in our
         future success through  distributions and appreciation,  if any, in our
         share  price.  HRP has agreed not to sell these shares for at least one
         year; thereafter HRP may realize value from its ownership of our shares
         by selling these shares.
    

Lack of Prior Market for the Common Shares

     Prior to this  offering no public market for our common shares has existed.
The market  value of the common  shares may decline if no active  market for the
common shares  develops.  After the completion of this offering,  we expect that
the common shares will trade on the NYSE,  but we can provide no assurance  that
an active trading market will develop.

Possible Future Sales of Common Shares

   
     Our Board of Trustees  has the ability to  authorize  and issue  additional
common shares in the future without shareholder approval. If we issue additional
common shares,  the market value of our common shares may decline.  In addition,
the HRP shareholders  receiving our common shares as an HRP distribution will be
free to sell them.  HRP and  Messrs.  Portnoy and Martin have agreed not to sell
the  common  shares  they will own for at least one year  after  this  offering;
thereafter they may sell their
    
                                       15

common shares.  An oversupply of shares offered for sale could adversely  affect
the market price of our common shares.

Tax Risks

   
     We intend to qualify as a REIT under the Internal  Revenue Code of 1986, as
amended (the "Tax Code").  The requirements for this  qualification are complex.
If we fail to satisfy these requirements, we may have to pay corporate taxes and
we will have less money available for distributions.
    

Risks of Debt Leverage

   
     Our   Declaration  of  Trust,   By-laws,   investment   policies  or  other
organizational documents do not restrict our ability to borrow money. As a REIT,
we will use most of our available cash flow to make distributions.  Accordingly,
our ability to repay debt will  generally  depend upon our ability to refinance.
If we incur  excessive debt or are unable to refinance debt before its maturity,
either because of market  conditions or for other  reasons,  we may be unable to
make distributions or to remain in business.  We expect to incur secured debt. A
default on secured debt may result in foreclosure on our mortgaged properties.
    

Ownership Limitations and Anti-Takeover Provisions

     Our Declaration of Trust prohibits any shareholder  other than HRP, RMR and
their  affiliates from owning more than 9.8% of our  outstanding  common shares.
This provision of the Declaration of Trust will assist us to comply with certain
REIT tax  requirements.  This provision will also inhibit a change of control of
our Company.  Our Declaration of Trust and By-laws contain other provisions that
may increase the  difficulty  of acquiring  control of our Company by means of a
tender  offer,  open  market  purchases,  a proxy  fight or  otherwise,  if such
acquisition  is not  approved  by our  Board of  Trustees.  These  anti-takeover
provisions  include the following:  (1) a staggered Board of Trustees with three
separate  classes;  (2) the availability of additional  shares that the Board of
Trustees may authorize and issue on terms that it determines;  (3) the inability
of the shareholders to act by written consent; and (4) advance notice procedures
with respect to nominations of trustees and  shareholder  proposals.  For all of
these  reasons,  our  shareholders  may be unable to realize a change of control
premium for their shares.

Policy Changes

     The Board of Trustees has the power to change our  investment  and business
policies without  shareholder  approval.  This means the Board of Trustees could
change the type of properties in which we invest,  the type of tenants with whom
we do business, the amount of debt we assume or otherwise increase the types and
levels of risks we assume.

Properties Subject to Ground Leases

     We lease the land  underlying two of our properties  under long term ground
leases. The tenants of our properties located on ground leased land must pay the
ground rents and comply with the ground  leases.  If our tenants fail to perform
these  obligations,  we may have to perform  the  ground  lease  obligations  to
protect our  investment  in these  properties.  The total  amount of ground rent
required during the year ended September 30, 1998 was $138,100.

Dilution

     HRP has owned and  depreciated  our initial  properties  for several years.
Because HRP will own 35% of our  Company,  GAAP  requires  that we report  these
assets at their historical cost to HRP net of depreciation  previously  expensed
by HRP. As a result of this  depreciation  previously  expensed by HRP and other
factors,  our net book value per share after completion of this offering will be
$12.56 per share.  Since the expected public offering price is approximately $19
per share, you will experience immediate dilution of $6.44 per share, or 33.9%.

                                  DISTRIBUTIONS

     After  completion  of this  offering,  we intend to make regular  quarterly
distributions to shareholders.  The initial distribution for the quarter ended ,
1999, is expected to be $0. per share,  and  represents the pro rata amount of a
quarterly  distribution  from the completion of this offering through the end of
this quarter. The initial regular quarterly  distribution of $0.40 per share (or
$1.60 per share on an annual basis) represents a yield of 8.42% per annum of the
estimated  initial  offering price of $19.00 per share. We intend to maintain at
least the initial  distribution rate for one year following this offering unless
our  operating  results  differ  materially  from what we now expect.  We do not
intend to reduce the  initial  distribution  rate if the  underwriters  exercise
their over-allotment option.

     We expect  that our  distributions  will  exceed  our  earnings  because of
non-cash  expenses,  primarily  depreciation and amortization.  Distributions in
excess of earnings  represent return of capital for federal income tax purposes.
Assuming  that our  distribution  rate  remains  unchanged  in the  year  ending
December 31, 1999, and that our earnings for this period are as estimated in the
table below (pro rata  adjusted for the period from  completion of this offering
through December 31, 1999), we estimate that % of our distributions in 1999 will
be reportable by  shareholders  as a return of capital for federal income taxes.
Under  current law,  distributions  in excess of earnings  which are a return of
capital are not taxable but these amounts  reduce a  shareholder's  basis in his
shares,  and,  accordingly,  increase  taxable  gains when shares are sold.  The
percent  of  annual  distributions  which  will be a return of  capital  for tax
purposes will vary from year to year. For a more detailed  discussion of the tax
consequences of our distributions, see "Federal Income Tax Considerations."

     The  initial  distribution  rate was set  based  upon our  estimate  of the
minimum FFO we believe we will realize  during the year following this offering.
All future distributions will be set by our Board of Trustees. When deciding the
amount of future  distributions  we expect the Board of Trustees will  primarily
consider the actual FFO  realized and  projections  of future FFO.  However,  in
making  these  decisions  the  Board may  consider  other  factors  such as cash
available for distribution,  capital  requirements,  the legal requirements that
REITs  distribute at least 95% of net taxable earnings and such other factors as
the Board deems  relevant from time to time. The amount of future FFO and future
distributions is not now known or knowable and they can not be assured.

     The following table sets forth our calculation of estimated  earnings,  FFO
and cash available for  distribution  for the year  following this offering.  In
making these estimates we have started our calculation  with historical  audited
operating  results  and made  adjustments  to reflect  known  events  which have
occurred and events which we expect to occur at or shortly after the  completion
of this offering. In this calculation no effect is shown from changes in working
capital (i.e.,  changes in current assets or current  liabilities) because these
changes are not expected to be material.  Similarly,  other than  completion  of
this offering at $19.00 per share and the use of proceeds from this offering, no
effect is shown from possible future financings or investing  activities because
these activities can not now be estimated.  In considering this table you should
recognize  that FFO and cash  available  for  distribution  may not be as good a
measure of  operating  performance  as earnings  determined  according  to GAAP.
Similarly,  FFO  and  cash  available  for  distribution  are  not  intended  to
substitute  for cash flow  determined  according  to GAAP.  Cash  available  for
distribution is presented  because it may be a relevant basis for you to compare
our operations with those of other REITs and because it may be considered by our
Board of Trustees in setting distributions.  FFO is presented because we believe
it will be a basis used by analysts to compare our operating  results with those
of other REITs,  because we used it to set the initial  distribution  rate,  and
because  we expect it will be an  important  consideration  used by our Board of
Trustees to determine future distributions.

     Our current  properties  have been owned and depreciated by HRP for several
years.  In  accordance  with GAAP we will record  HRP's  historical  cost net of
previously claimed  depreciation on our balance sheet. The following table shows

      The net  proceeds  from this  offering  are  expected to be  approximately
$195.4 million (or $224.7 million if the underwriters'  over-allotment option is
exercised in full). In addition, we expect to receive approximately $6.7 million
in cash proceeds from the sale of 350,000  common shares to Messrs.  Portnoy and
Martin.  We will use the proceeds of this offering and the simultaneous  sale to
our Managing Trustees as follows:

 Purchase of 14 new Marriott properties........................$193.8 million
 Fees and expenses of the offering.............................   2.0 million
 General business purposes (including other acquisitions)......   6.3 million

      If the new Marriott properties are not completed by the time this offering
is  completed,  or if for any reason we do not acquire  all of the new  Marriott
properties,  we will use the additional  available proceeds for general business
purposes, including new acquisitions.  This offering is not conditioned upon the
acquisition of any properties from Marriott. If the underwriters' over-allotment
option to purchase  common  shares is  exercised,  we will use the net  proceeds
received for general business  purposes,  including new acquisitions.  Until net
proceeds  are used as  described  herein  they  may be  invested  in short  term
securities, some of which may not be investment grade rated.

                                   THE COMPANY

     Our  Company is a REIT  organized  under  Maryland  law to acquire  and own
senior housing,  congregate communities,  assisted living properties and nursing
homes that are leased to  unaffiliated  tenants.  We currently own 84 properties
and have entered a commitment to acquire and lease an additional 14  properties.
These 98  properties  have 13,750  units/beds  and are leased to nine  different
groups of affiliated tenants, none of which are affiliated with our Company.

Formation

     We were  created as a separate  subsidiary  of HRP on  December  16,  1998.
Before the closing of this offering HRP will contribute 84 properties to us. HRP
has entered into an agreement with Marriott to acquire 14 additional  properties
which will be leased to two Marriott  subsidiaries.  This  acquisition and lease
agreement  will be  assigned  to us prior to the  closing of the  offering.  The
closing  of this  acquisition  and  lease  will  occur  simultaneously  with the
completion of this offering.

   
     None of the 84 properties  now owned by HRP that will be  transferred to us
are  presently  encumbered  by mortgage  debt and all were acquired by HRP since
1987.  Prior  to the  closing  of  the  offering,  HRP  will  contribute  the 84
properties to its subsidiaries. We will issue a note to HRP for $250 million, as
partial  consideration for the contribution of those properties.  Shortly before
the  closing of the  offering,  HRP will  contribute  the  capital  stock of the
subsidiaries  holding  the 84  properties  to us and we will  become  a  holding
company.  Immediately  after the closing of this  offering,  we will borrow $250
million from commercial banks and will use these loan proceeds to repay the loan
from HRP. The new bank loan will be secured by first  mortgages on the 14 senior
living properties.

     At the time we were organized we had 26,374,760 shares outstanding,  all of
which were owned by HRP.  Upon the closing of this  offering  13,187,380  of our
common shares will be distributed to HRP shareholders on the basis of one of our
shares for each 10 shares of HRP held of record on _____,  1999.  No  fractional
common  shares will be issued.  Cash in lieu of  fractional  shares will be paid
using the public  offering  price per share as the value for our common  shares.
Also,  simultaneously  with the closing of this  offering,  Messrs.  Portnoy and
Martin will purchase 350,000 of our shares at the same gross price as is paid by
public investors. At the conclusion of these offerings,  HRP will own 35% of our
shares,  Messrs.  Portnoy  and Martin will own 1% of our shares  (including  the
350,000  shares to be purchased and their  pro-rata  distribution  as beneficial
owners of HRP) and the public generally (including former public shareholders of
HRP) will own 64% of our shares.

    
     We are currently  negotiating a new $100 million revolving credit facility.
We will use this credit facility for working capital and other general  business
purposes,  including  interim  financing  for  new  purchases  until  these  new
acquisitions  are  financed on a more  permanent  basis with term debt or equity
capital.

   
     Additional  details  of  our  formation  are  set  forth  in a  transaction
agreement,  which is described under "Summary of the  Transaction  Agreement." A
copy of the  transaction  agreement has been filed with the SEC as an exhibit to
the registration  statement of which this prospectus is a part. If you want more
information about our formation you should review that document.

History and Management

   
     Our  operations  will be conducted by RMR. RMR has  approximately  180 full
time employees, including a headquarters management staff, four regional offices
and other personnel located throughout the United States. RMR and its principals
have experience in managing the REITs to produce  increasing  distributions  and
have extensive contacts in the senior housing and healthcare industries.

     The principals of RMR,  Barry M. Portnoy and Gerard M. Martin,  founded HRP
in 1986 as a  public  company  with $63  million  invested  in seven  healthcare
properties  leased to two tenants.  Since 1986,  under the  direction of Messrs.
Portnoy  and  Martin  and  other  RMR  personnel,  HRP has grown to have over $3
billion  invested in 255  properties  leased to over 500 tenants.  During its 12
years in business, HRP has made 48 consecutive quarterly distributions.  HRP has
increased  its  distribution  rate  13  times,  and  has  increased  its  annual
distribution every year it has been in business.

     RMR and its principals have previously  successfully organized and operated
another  public REIT in  addition  to HRP.  In 1995 RMR and  Messrs.  Martin and
Portnoy organized HPT, a REIT that invests in hotel  properties.  At its initial
public  offering  in August  1995,  HPT had $329  million  invested in 37 hotels
leased to one tenant (21 hotels  were  previously  owned by HRP).  Today HPT has
almost $1.8 billion invested in 167 hotels leased to nine tenants, none of which
are  affiliated  with  RMR.  Since  it was  founded  in  1995,  HPT  has  raised
approximately  $1.5  billion  of  capital  and  made  14  consecutive  quarterly
distributions,  and increased its  distribution  rate nine times.  In 1998,  HPT
became  the first and is the only  hotel  REIT  with  senior  debt that is rated
investment  grade by  Moody's  Investors  Service  and  Standard  & Poor's.  HRP
continues to own 4 million shares of HPT.
    

     Starting in the early  1990's HRP began to invest in  multi-tenant  medical
office  buildings.  In 1997 HRP purchased a large portfolio of office  buildings
leased to the U.S.  Government.  During 1997 and 1998 substantially all of HRP's
new investments have been in commercial office properties, and HRP has made very
few  purchases  of senior  housing  properties  or  healthcare  facilities.  RMR
believes that current market  conditions make a renewed focus on senior property
investments appropriate at this time.
Specifically:

o    New properties  developed by start up assisted living  companies during the
     past few years are being  completed and a large number of  properties  that
     are operating successfully are now available for investment.

o    The current shortage of debt and equity capital for real estate investments
     has reduced the  financing  options  available to senior  housing  property
     owners  and  limited  the  amount  of  new  development   activities  being
     undertaken.

o    New Medicare  prospective  payment regulations became applicable to nursing
     homes on July 1, 1998, and their impact upon the  profitability  of nursing
     home properties can now be reasonably estimated.

o    The  combination  of the  foregoing  circumstances  has made the pricing of
     senior housing, congregate community,  assisted living property and nursing
     home  purchases and leases more  attractive  than they have been during the
     past three years.

     A primary  purpose of this offering is to capitalize  separately a new REIT
with a strong core of senior  housing real estate,  and  management has industry
contacts that can take advantage of the market  conditions  outlined  above.  To
facilitate  these efforts two senior  officers of RMR will be assigned to devote
substantially  all of their  business  time to  growing  our  Company.  David J.
Hegarty is currently the President and Chief  Operating  Officer of both RMR and
HRP. Ajay Saini is currently a Vice President

                                       24
<PAGE>

of RMR and Treasurer and Chief Financial Officer of HRP. Upon completion of this
offering,  Messrs.  Hegarty and Saini will  resign  their  positions  at HRP and
assume similar positions at our Company.  All other RMR personnel  including our
Managing Trustees,  Messrs.  Portnoy and Martin,  will also devote a significant
part of their time to assist in this effort.

Growth Strategy

     The population of the United States is aging. According to information from
the U.S.  Census Bureau,  the segment of the U.S.  population age 85 and over is
increasing and is expected to increase sharply through the year 2020. We believe
that this demographic fact will increase the demand for existing senior housing,
congregate  communities,  assisted  living  properties  and  nursing  homes  and
encourage  development  of new  properties.  Certain  recent  federal  and state
legislation  seeks to limit the amount of growth in government  expenditures for
Medicare and Medicaid.  We believe that the net effect of these  demographic and
legislative  changes will be to make it less profitable to provide  services and
facilities  for  government  funded  patients  and more  profitable  to  provide
services and facilities for non-government funded patients. Our business plan is
to profit from the 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.  Although we may invest in some older properties
at  appropriate  purchase  and lease  price  terms,  we expect  that our  future
investments  will focus upon  properties  similar  to the new  properties  to be
acquired from Marriott.  We expect these newer  properties to attract  residents
who use private resources,  rather than government programs, to pay for rent and
services.

Senior Living Real Estate Market

     Demand  Growth.  There are several  important  demographic  trends which we
expect will increase demand for senior housing, congregate communities, assisted
living  properties  and  nursing  homes  for  the  foreseeable   future.   These
demographic  trends  are so  powerful  that we  believe  they will  continue  to
increase  this  demand  with  only  modest  impact  from  usual  business  cycle
pressures.

     The U.S.  Census Bureau has projected that the U.S.  population over age 85
will  increase  from 3.1 million in 1990, to 4.3 million in 2000, to 5.7 million
in 2010 and to 6.5 million in 2020. As people age they have an  increasing  need
for the type of  assistance  with daily  living  activities  that is provided in
senior housing,  congregate communities,  assisted living properties and nursing
homes.  This is because  old age is  usually  accompanied  by  various  physical
disabilities  and  because  the  aging  process   sometimes  is  accompanied  by
Alzheimer's disease and other forms of dementia that require specialized, secure
housing.

     Certain  societal  changes  during the past 35 years in the U.S.  have made
senior housing,  congregate communities,  assisted living properties and nursing
homes more often required than in historical periods. The increasing  percentage
of women  working  away from their  homes,  the high  divorce  rate and societal
mobility have all combined to make  traditional  arrangements of family care for
aging relatives less available.  These social trends show no sign of reversal in
the foreseeable future.

     Economic factors appear to encourage  demand of specialized  senior housing
properties.  Although  some people extol the benefits of homemaker  services and
home healthcare,  it is generally more economically  efficient to congregate the
elderly in properties with specialized  services than to bring those services to
diverse locations. Similarly, the cost containment pressure to reduce lengths of
stay for the elderly in high cost  specialized  properties such as hospitals has
increased the need for intermediate care properties.

                                       25
<PAGE>

     Types of  Properties.  We expect to  invest  in four  types of  properties,
including  some  properties  that  combine  more than one type of  property in a
single building or campus.

         Senior housing. Senior housing 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.
According to a 1997 study by PricewaterhouseCoopers LLP, monthly charges paid by
residents in senior apartments typically vary from $600 to $1,200 per month.

         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  certain  services  as  part  of a  regular  monthly
charge--for  example,  one or two meals per day in a central dining room, weekly
maid  service,  a social  director,  in addition  to  concierge  services,  etc.
Additional   services  are  generally   available  from  staff  employees  on  a
fee-for-service charge basis. According to the 1997  PricewaterhouseCoopers  LLP
study, monthly charges at congregate  communities typically range from $1,400 to
$2,000 per month.  Luxury  properties  of this type similar to those that we own
and lease to Marriott and  Brookdale  often charge higher rates up to $5,000 per
month.

         Assisted living  properties.  Assisted living  properties are typically
composed of 300 to 750 square  feet 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 health related  services are
usually available at the facility on call or at regularly scheduled times. Since
the early  1990's  there  has been an  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   our   Company.    According   to   the   1997
PricewaterhouseCoopers  LLP  study,  residents  in  assisted  living  properties
typically  pay $2,400 to $3,000 per month.  Luxury  properties  in this category
similar to the new  properties we expect to purchase and lease to Marriott often
charge as much as $3,500 per month.

         Nursing homes.  Nursing homes generally  provide  extensive nursing and
health-related  services  similar to those found 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 but with 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. According
to the 1997  PricewaterhouseCoopers  LLP study, monthly charges at nursing homes
typically  are $2,800 to $4,000 per month.  At the nursing homes that we own and
lease to Mariner  Post-Acute Health Network and Integrated Health Services,  the
average monthly charge in 1998 are approximately $3,000 to $4,500 per month.

     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 1995 has attracted a number of residents away
from nursing homes.  This was especially  significant  because the residents who
elected  assisted  living  facilities  had 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.
According to a 1998 study by SMG Marketing Group, Inc., the average occupancy of
U.S. nursing homes declined from 93% in 1994 to about 88% in 1997.

                                       26

<PAGE>

     The second major  challenge  arose as a result of 1997 federal  legislation
that required the Medicare  program to implement a prospective  payment  program
for various subacute  services  provided in skilled nursing homes. This Medicare
prospective  payment  program began to be implemented 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 charges that were implemented for hospitals during the
1980's.

     Starting in 1995 HRP's management believed that the market value of nursing
home  properties  did not  adequately  reflect the negative  impact of these two
changed market conditions.  For this reason beginning in 1996 HRP began to limit
its nursing  home  purchases  and it began to sell its nursing  home  properties
which were  dependent  upon subacute  services paid by Medicare.  We now believe
that the  market  is in the  process  of taking  account  of these  factors  and
adjusting  the prices of  nursing  home  properties.  We also  believe  that the
demographic  factors described above combined with these adjusted pricing levels
make nursing home properties  attractive  investments at this time. We expect to
focus our assisted living and nursing home investments in facilities that have a
high percentage of non-government  revenues.  When we invest in  assisted-living
properties and nursing homes that are dependent upon government revenues we will
attempt to set the  purchase  prices and rent rates at levels that are  securely
covered by existing and projected cash flows from our tenants' operations.

Government Regulations and Rate Setting

     We believe the degree of  government  regulation of the types of properties
in which  we  intend  to  invest  seems  to be  proportional  to the  amount  of
government   money  available  to  pay  for  occupancy  and  services  at  these
properties.

     Senior Housing.  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 limited to zoning,  building and fire codes, Americans with Disabilities Act
requirements  and other life safety type  regulations  applicable to real estate
generally.  Government  rent subsidies for low income senior housing  provide an
exception to this  general  statement.  Government  rent  subsidies  are usually
available for properties that also qualify for government  assisted  development
financing.  The  development  and operation of these  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  payment
programs are not available to congregate communities and the resident charges in
such  properties  are paid from  private  resources.  However,  certain  Federal
Supplemental  Security  Income  (SSI)  program  benefits  pay housing  costs for
elderly or disabled  residents to live in certain  residential  facilities.  The
Social  Security Act requires  states to certify  that they will  establish  and
enforce  standards,  such  as  licensing  or  certification  standards,  for any
category  of group  living  arrangement  in which a  significant  number  of SSI
residents  reside or are likely to  reside.  Categories  of living  arrangements
which may be subject to such state standards  include  congregate  facilities or
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

                                       27

<PAGE>

offices on aging,  with  jurisdiction  over  group  residential  facilities  for
seniors.  To the extent  that  congregate  communities  maintain  units in which
assisted living services or nursing facility services are provided to residents,
these units will  typically also be subject to state  regulations  applicable to
such  facilities.  In some  states,  insurance or consumer  protection  agencies
regulate  congregate  communities in which residents pay entrance fees or prepay
other costs.

     Assisted  Living.  A 1998 study by the  National  Academy for State  Health
Policy  listed,  as of June 1998, 28 states that 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 another eight states that planned to do so.
Because rates paid to assisted  living  property  operators are lower 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.  Each of the states that
administers   these  Medicaid   programs  for  assisted  living   facilities  is
responsible  for monitoring the services at these  facilities and monitoring the
physical conditions and maintenance 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 waivers or state plans
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.  According  to the 1998  National  Academy for State  Health
Policy Report, as of June 1998, 33 states had taken steps to implement  assisted
living  policies,  and 11 others had  instituted  processes  to study the issue.
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,  the 1998
National Academy for State Health Policy study referenced above found six states
(New York,  New Jersey,  Illinois,  Kentucky,  Connecticut  and  Missouri)  that
require  certificates of need from state health planning  authorities before new
assisted living properties may be developed.  Also, the study found three states
(North Carolina,  Arkansas and North Dakota) that have adopted  moratoria on the
development of new assisted  living  facilities.  It is our belief 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.  It is also our belief 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 in areas  where there are  barriers  to  competition
created by certificate of need laws or otherwise.

     Two federal government studies are currently underway to provide background
information and make recommendations  regarding the future regulation of and the
possibility of increased  governmental funding for the assisted living industry.
One study is being  conducted by the General  Accounting  Office ("GAO") for the
Senate  Special  Committee on Aging and is focused upon consumer  protection and
quality of care issues.  The second study,  being conducted by the Department of
Health and Human Services'  Assistant  Secretary for Planning and Evaluation (of
which the 1998 National  Academy for State Health Policy study  referenced above
is part) is expected to touch upon all aspects of the assisted  living  industry
including  quality of care and  financing.  These  studies  are  expected  to be
completed  during 1999. We cannot  predict  whether these studies will result in
governmental  policy changes or new legislation,  or what impact any changes may
have. 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

                                       28
<PAGE>

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  conditions  of nursing  home  properties.  These  periodic
inspections   and   occasional   changes  in  life  safety  and  physical  plant
requirements  sometimes  require nursing home owners to expend money for capital
improvements.  Fortunately, however, these mandated capital improvements usually
result  in  Medicare  and  Medicaid  rate  adjustments,  albeit  on the basis of
amortization of expenditures over extended useful lives of the improvements.

     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 that have  eliminated  certificate of need laws (for example,  California
and Texas) the state health  authorities  usually have  retained  other means of
limiting new nursing  home  development,  such as the use of  licensing  laws or
limitations upon  participation in the state Medicaid  program.  We believe that
these governmental limitations generally extend the useful lives of nursing home
properties and make them more valuable as local quasi- monopolies.

Competition

     Several REITs which own apartments  have focused some of their  investments
on senior housing apartment buildings.  In addition,  there are several publicly
owned REITs that are today  focused upon  investing in  healthcare  real estate.
Also,  some asset based finance  companies and banks have marketing  programs to
provide sale  leaseback and mortgage  financing  for these types of  properties.
Some of these  competitors have resources that are greater than we will have and
some have a cost of capital that may be less than we will have. Nonetheless,  we
believe that we will be able to successfully  compete for new investments for at
least five reasons:

     First,  our  initial  senior  living   properties  have  solid  records  of
performance. We will commence business with a large and diversified portfolio of
properties  which have  strong  prospects  based on  demographic  trends and are
subject to long term leases.

     Second,  we will be the only REIT  exclusively  focused  on  senior  living
properties. We do not intend to invest in medical office buildings, hospitals or
any  properties  which do not benefit from the  projected  aging of the American
population.

     Third,  current market  conditions  have created an  opportunity  for a new
market entrant to purchase and lease senior living properties. A large number of
recently developed  properties are currently  available.  The current turmoil in
the mortgage markets has limited capital for new development and has reduced the
financing  available  to  several  of  our  competitors.  Also,  a new  Medicare
prospective  payment  program  has caused  nursing  homes to be revalued so that
purchase prices and rents can be set at levels which are well covered by current
and projected property operations.

     Fourth,  our  proposed  methods  of  doing  business  are  intended  to  be
attractive to a diversified  group of prospective  sellers and tenants of senior
living properties.  We intend to do business only with unaffiliated  sellers and
tenants and to retain the financial flexibility to work with our tenants to meet
their  business  requirements.  Some of our REIT  competitors  are under  common
control  with large  tenants.  This fact often  makes  unaffiliated  sellers and
tenants reluctant to disclose the operating

                                       29
<PAGE>

information  necessary  for  a  successful  transaction.  Some  of  the  finance
companies that target  healthcare  property  investments and certain  healthcare
REITs that emphasize  mortgage lending depend upon the asset backed bond markets
for funding.  Asset backed  financing has  historically  afforded  borrowers and
tenants  very  limited   flexibility  to  adjust  mortgage  or  lease  terms  to
accommodate changes in the tenants' businesses during long term leases. Although
we may  borrow on a  secured  basis,  we  expect  to retain  title to all of our
property  investments  in order to work  with  tenants  to meet  their  business
requirements.

     Finally,  and perhaps most  importantly,  our management team has extensive
experience  and  contacts  in the senior  housing  and  healthcare  real  estate
markets. Our initial tenants will include affiliates of six public companies and
three private  companies.  Although we cannot be sure that we will do additional
business with these tenants we believe we have solid relationships with them.

Marriott International, Inc.

     Marriott is a NYSE listed company.  In addition to operating  senior living
properties  such as those  leased  and to be leased  from us,  Marriott's  major
businesses are developing,  operating and managing hotels and time-share  resort
communities.  At September  11, 1998,  Marriott had a book value of $2.6 billion
and on December 17, 1998 had an equity market capitalization of $6.8 billion.

     We currently own 14 congregate  communities and assisted living  properties
with 3,932 units that are leased to  subsidiaries  of Marriott.  The annual rent
under this lease is $29.5  million.  This lease expires in 2013 and Marriott has
renewal  options  totalling an additional 20 years.  Marriott has guaranteed all
obligations due to us under this lease.

     The proceeds  from this  offering  will be used to acquire an additional 14
new assisted living  properties  with 1,803 units from  subsidiaries of Marriott
that will be leased back to two Marriott subsidiaries under two leases for seven
properties  each.  The rent  under  these  leases  initially  will  total  $20.3
million/year.  These  leases  will  expire in 2014 and 2016,  respectively,  and
Marriott  has renewal  options  totalling an  additional  20 years and 18 years,
respectively.  Marriott will guarantee 100% of the  obligations  due to us under
these leases for the first full year and,  thereafter,  until the sooner of: (1)
payment by Marriott of 25% of our purchase price for all 14 properties; (2) when
the combined cash flow generated by the tenants'  operation of these  properties
covers the rent by 1.3 times as determined  by an annual audit;  or (3) the year
ended 2006.

     Marriott will have guaranteed  approximately  56% of our annual revenues at
the completion of this offering.  The following tables present summary financial
information  about Marriott  derived from Marriott's  Annual Report on Form 10-K
for the year  ended  January 2, 1998 and  Quarterly  Report on Form 10-Q for the
quarter ended September 11, 1998. If you want more information about Marriott or
any of our other publicly owned tenants you should study the public  information

Lease Terms

         All of our leases are so called  "triple net" leases which  require our
tenants to maintain our properties during the lease terms and to indemnify us by
reason of our ownership of the leased properties.  The following is a summary of
certain  material  terms of our leases in addition to the terms set forth in the
foregoing chart. Our material leases have been filed with the SEC as exhibits to
our registration  statement of which this prospectus is a part. If you want more
information about our leases you should review that document.

         Cross  Default.  Whenever  we lease more than one  property to a single
tenant or a group of affiliated tenants all those leases are cross defaulted. In
the  case of our  Marriott  tenants,  however,  the  leases  affecting  existing
properties are subject to cross default and the leases  affecting new properties
are subject to cross default, but leases for the existing properties and for the
new properties are not subject to cross default with each other.

         All or None Renewal  Options.  Whenever 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.  This means that a tenant or group of
affiliated  tenants  cannot  decide  to  exercise  renewal  options  for  strong
performing  properties unless it also renews the leases for all other properties
leased  from us.  In the  case of our  Marriott  tenants,  however,  the  leases
affecting existing properties are subject to all or none renewal options and the
leases affecting new properties are subject to all or none renewal options,  but
leases for the existing properties and for the new properties are not subject to
all or none renewal options with each other.

         Maintenance  and  Alterations.  Each  of our  tenants  is  required  to
maintain,  at its  expense,  our leased  properties  in good  order and  repair,
including  structural and nonstructural  maintenance.  Except in the case of the
existing Marriott  properties,  capital  alterations and additions to any leased
property,  the aggregate cost of which exceeds a threshold  amount,  may only be
made with our prior consent.  Any alterations or improvements made to any leased
property  during the term of the  leases  become  our  property,  subject to our
obligation to pay to the tenants certain 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
date of the leases, subject to any permitted alterations and subject to ordinary
wear and tear.

         In the case of the new Marriott  properties only, a percentage of total
revenues from these  properties  (beginning at 1% and increasing to a maximum of
3.5%) is  deposited  in a reserve  to pay for the costs of certain  repairs  and
replacements.   If  deposited  funds  are  insufficient  to  cover  repairs  and
maintenance  costs  at  these  properties,  we  will  fund  the  amount  of  the
deficiency,  and the rent which we receive  will  increase  by a minimum  annual
amount equal to 10% of the amounts funded.

         Assignment.  Our consent is generally  required for any  assignment  or
sublease of our  properties.  In the event of a subletting,  the initial  tenant
remains primarily liable 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 or to pay any
costs we incur in  connection  with  such  removal  and  disposal.  Each  tenant
indemnifies us for any claims  asserted as a result of the presence of hazardous
substances  at any  property or 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:  (1)
comprehensive  general liability for damage to property or bodily injury arising
out of the  ownership,  use,  occupancy or maintenance  of the  properties;  (2)
commercial   property  "all  risk"   liability   for  damage  to   improvements,
merchandise, trade fixtures,  furnishings,  equipment and personal property; (3)
workers'  compensation  liability;  (4) business  interruption loss; (5) in some
cases,  medical  malpractice;  and  (6)  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,  explosion or other  casualty or is taken or condemned for a
public use, we receives  all proceeds and the tenants are required to pay us any
difference  between the amount of proceeds and our  aggregate  investment in the
affected  property.  In certain  cases,  tenants  have a right to  purchase  the
affected property for amounts at least equal to our historical investment in the
property.

         Events of  Default.  Events of  default  under our leases  include  the
following:  (1) the failure of the tenant to pay rent when due;  (2) the failure
of the tenant to perform  certain of the terms,  covenants or  conditions of its
lease and the continuance  thereof for a specified  period after written notice;
(3) the occurrence of certain  events of insolvency  with respect to the tenant;
(4) the failure of the tenant to maintain required insurance  coverages;  or (5)
the revocation of any material license  necessary for the tenant's  operation of
our property.

         Remedies.  Upon the  occurrence  of any event of  default,  subject  to
applicable  law, we may: (1) terminate  the affected  lease and  accelerate  the
rent;  (2) terminate  the tenant's  rights to the affected  property,  relet the
property  upon  terms  satisfactory  to us,  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 (3) 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 the  properties  is
subject  to  ground  leases.  The  leases  with  respect  to the  ground  leased
properties are subject to early  termination if the applicable ground leases are
terminated.  Our leases  require the tenants to pay and perform all  obligations
arising under the  applicable  ground  leases.  These ground  leases,  including
extension  options,  terminate on 2086 and 2079.  The annual rents payable under
the ground leases in 1998 totaled $138,100.

        SELECTED HISTORICAL AND ADJUSTED PRO FORMA FINANCIAL INFORMATION

         The  following  table  presents   historical  and  adjusted  pro  forma
financial information and other data for our properties. We are currently a 100%
owned  subsidiary of HRP, and none of our  properties are encumbered by debt. It
is  impossible  to estimate all  operating  expenses we would have incurred as a
separate  public company.  The following table includes pro rata  allocations of
interest expense and certain general and administrative  expenses for historical
periods.  However,  the net  income  and  funds  from  operations  shown are not
necessarily  indicative  of results that we will realize as a separate  company.
The adjusted pro forma information  assumes that this offering is completed at a
public  offering price of $19 per common share and that net proceeds are used to
purchase and lease 14 new Marriott properties including  adjustments for certain
properties under development.  For additional  information about the calculation
of  amounts  appearing  in this  table see the  Unaudited  Pro  Forma  Financial
Statements and notes thereto included elsewhere in this prospectus.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following should be read in conjunction  with the "Selected  Historical
and Adjusted Pro Forma Financial  Information" and the financial  statements and
notes thereto included elsewhere in this prospectus. As pointed out elsewhere in
this  prospectus,  our Company did not exist until December 16, 1998. A majority
of our properties have been  historically  owned by HRP  unencumbered by secured
debt.  In these  circumstances  it is not  possible  to estimate  all  operating
expenses which we would have incurred in historical periods as a separate public
company.  The  financial  statements  which are analyzed  below include pro rata
allocations of interest expense and certain general and administrative  expenses
to the  historical  results  realized by HRP from  ownership of our  properties.
Accordingly,  you should  understand  that the results of  operations  discussed
below are not  necessarily  indicative of the  operating  results which we would
have realized as a separate company during these historical periods.

Overview

     We  will  initially  have  investments  in  98  properties,   including  14
properties  which will be acquired  with the  proceeds of this  offering  and 84
which will be transferred to us by HRP upon completion of this offering. Nine of
these  investments  will be in properties  for which we have  provided  mortgage
financing  and  for  which  we  hold  nominal  price  purchase  options.  Our 98
properties  contain  13,750  units or beds and are located in 23 states.  During
1998 our properties had an average occupancy rate of 88%.

     Our 98  properties  are  leased  to nine  different  groups  of  affiliated
tenants.  None of these  tenants  are  affiliated  with us.  Tenants  which  are
subsidiaries  of publicly owned companies  account for 98% of our revenues.  Our
most important tenant,  Marriott,  is responsible for 56% of our total revenues.
Ninety-four  percent  of our  revenues  arise from  leases  which  expire  after
December  31, 2010.  The Marriott  leases  expire after  December 31, 2013.  Our
tenants have extensive  renewal options.  Our leases require our tenants' to pay
minimum rents plus additional  rents based upon increases in tenants'  revenues,
increases in the Consumer Price Index or fixed annual amounts.

Adjusted Pro Forma Results of Operations

     Nine  Months  ended  September  30,  1998.  Adjusted  pro forma  results of
operations for the nine months ended September 30, 1998,  compared to historical
results for this period include  increases in rental income,  interest  expense,
deprecation  and general and  administrative  expenses  of $16.7  million,  $1.6
million, $3.5 million and $.8 million, respectively. The effect of these changes
is to increase net income by $10.3 million and to increase funds from operations
by $13.8 million. These increases result from our proposed purchase and lease of
the 14 new Marriott  properties  and the $250 million  mortgage  financing of 14
other properties owned during the historical period.

     Certain of the results  presented in the adjusted pro forma information for
this nine month period  include the effects of properties  to be acquired  which
were under  construction  during this period.  The  adjusted  pro forma  results
reflect  revenue and expenses of $13.5 million and $3.5  million,  respectively,
related to  properties  in  construction  during this period.  We believe all or
almost all of these  properties will be constructed  prior to completion of this
offering or shortly  thereafter.  Accordingly,  we believe that the Adjusted Pro
Forma Financial  Information provide certain important  information to investors
in this offering.

Historical Results of Operations.

     Years 1997 and 1996 compared. In 1997 compared to 1996, rental and interest
income increased by $12.0 million and $1.5 million,  respectively.  Depreciation
and  general  and  administrative  expenses  increased  by $2.4  million and $.5
million.  All of these changes  resulted  from  increased  investments  in seven
properties during 1996 and in five properties during 1997.

     During 1996 and 1997 all of our  properties  were owned or mortgaged by HRP
and none were  encumbered  by secured  debt.  The interest  expense shown on the
historical  financial statements reflects HRP's total interest expense allocated
to these properties pro rata among HRP's total investments,  at cost, during the
respective  periods.  The  increase in interest  expense of $2.1 million in 1997
from 1996 represents a larger  allocation of interest  expense to our properties
due to higher borrowings by HRP in 1997 compared to 1996 which is only partially
off-set by lower interest rates.

     As a result of these changes, net income and funds from operations realized
from  ownership of our  properties  in 1997  compared to 1996  increased by $8.5
million and $10.9 million, respectively.

     Years 1996 and 1995 compared. In 1996 compared to 1995, rental and interest
income increased by $3.0 million and $.2 million respectively.  Depreciation and
general and  administrative  expenses  increased by $.6 million and $.3 million.
All of these changes  result from increased  investments in seven  properties in
1995 and seven more properties in 1996.

     During 1996 the HRP interest expense allocable to our properties  decreased
by $1.6 million  from the  allocable  interest  expense in 1995.  This  decrease
reflects lower  allocations  of interest  expense to our properties due to lower
borrowing by HRP in 1996  compared to 1995 which is partially  off-set by higher
interest rates.

     As a result of these changes net income and funds from operations  realized
from  ownership of our  properties  in 1996  compared to 1995  increased by $4.0
million and $4.5 million, respectively.

Liquidity and Capital Resources

   
     At the  conclusion  of this offering we expect to have  approximately  $2.8
million in cash  available  for working  capital.  We expect this cash and rents
which we receive from our tenants on a monthly  basis will be sufficient to meet
our working  capital needs for  operating  expenses  (including  interest on our
debt) and to make regular quarterly distributions.
    

     We are currently  negotiating a new $250 million term loan.  This loan will
be secured by first  mortgages on the 14 Marriott  properties  we now own.  This
loan will close shortly after completion of this offering. The term of this loan
will be five years. Interest only payments will be required until maturity.  The
interest rate will be a floating  rate equal to LIBOR plus a premium.  We expect
that the loan documentation will have customary  representations  and warranties
from us and our  subsidiaries  which  own the  mortgaged  properties,  customary
covenants and events of default. Among other things, covenants would prohibit or
restrict  us from  selling  the  mortgaged  properties  while the  loans  remain
outstanding. If an event of default occurs, the loan documents would provide for
acceleration  of  outstanding  loans  and  an  increase  in  the  interest  rate
applicable to outstanding  amounts. In addition,  if an event of default occurs,
the lender  would have the right to  foreclose  on the  properties  securing the
loan. We will use the proceeds of this loan to satisfy a $250 million obligation
due HRP which we will incur as part of our formation  transaction.  This line is
expected to be provided by Dresdner Bank A.G.


                                       45
<PAGE>

     We are currently  negotiating a new $100 million  revolving loan. This loan
will be secured by a pledge of the stock of some of our subsidiaries.  This loan
will have a term of two years.  Interest only  payments  will be required  until
maturity.  The  interest  rate will be a  floating  rate  equal to LIBOR  plus a
premium.  We will have the right to repay and  redraw  amounts  under  this loan
facility  until its  maturity.  We expect that the line of credit  documentation
will have customary representations and warranties from us and our subsidiaries,
customary  affirmative and negative covenants and events of default. If an event
of default occurs,  the line of credit would likely provide for a termination of
our right to obtain additional  advances,  acceleration of outstanding loans and
an increase in the interest rate applicable to outstanding amounts. In addition,
if an event of default  occurs,  the lender would have the right to foreclose on
collateral  for the loans,  including the stock of our  subsidiaries.  We expect
this loan to close simultaneously with this offering. This loan will be provided
or arranged by an affiliate of Merrill Lynch & Co., our lead underwriter.  We do
not expect this loan  facility to continue  for periods  beyond the  maturity of
this loan.  After this  offering  is  completed  and before  this loan  facility
matures, we expect to enter negotiations with a syndicate of commercial banks to
provide a substitute revolving loan facility. This substitute revolving loan may
be for a larger amount and a longer maturity.

     After completion of this offering,  we intend to acquire  additional senior
living properties.  These purchases will be initially funded with excess working
capital  generated by our rents,  if any, and proceeds of  borrowings  under the
above described revolving credit facility.  After these properties are acquired,
they may be refinanced with long term debt or equity capital.  After  completion
of this offering, we expect to have: only $250 million of debt outstanding; book
equity of $474.0  million;  total real estate  assets,  at  historical  cost, of
$818.9 million; and total market  capitalization of approximately $966.8 million
(assuming a market price of $19/share). In these circumstances,  we believe that
we will have sufficient  access to capital markets to meet our growth objectives
and  refinance  our debt as  needed.  Of course,  however,  our access to growth
capital will depend upon numerous facts,  including some beyond our control; and
we can provide no assurance that we will be able to raise additional  capital in
sufficient  amounts, or at appropriate costs, to fund future growth or repayment
of our debt.

     Inflation. Inflation would have both positive and negative impacts upon our
business.  Inflation  would  cause the value of our real estate  investments  to
increase.  Similarly, in an inflationary environment, the additional rents which
we receive based upon CPI increases or as a percentage of our tenant's  revenues
should increase and rent yields we could charge for new investments would likely
increase.  Offsetting these benefits, inflation might cause the costs we pay for
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  contracts  whenever we have a large amount of floating  rate
debt outstanding and we believe  material  interest rate increases are likely to
occur. On balance,  we do not believe that the modest  inflation which we expect
may occur in the U.S.  economy  during the next few years will have any material
effect on our business.

     Deflation.  Deflation would have business  consequences to us which are the
inverse of the impact of inflation. If new construction costs decline, the value
of our existing real estate investments may decline.  The value of our long term
minimum rent leases might  increase but some tenants  might have trouble  paying
our rent in a  deflationary  environment,  and the amounts of our rent increases
might  decline or  disappear.  Deflation  might lower our costs of debt capital;
however,  deflation's  impact  on our  cost  of  equity  capital  is  uncertain.
Generally  we do not  believe  that the U.S.  economy  is likely  to  experience
serious  deflation in the foreseeable  future.  We believe that modest deflation
would  have no effect  upon our  business  and  serious  deflation  would have a
negative effect upon our business.

     Year 2000.  The computer  systems which we use for accounting and financial
reporting  were all updated or installed  within the past two years.  We believe
these systems are Year 2000 compliant.  All costs associated with these computer
systems are paid by RMR.

                                       46

     During  the past  year HRP has  directed  inquiries  to all of our  tenants
concerning  their  preparations  for Year 2000 computer  issues.  Based upon our
tenants' responses we believe all of our tenants are aware of possible Year 2000
issues  and  intend to take  steps to avoid  material  adverse  affects to their
businesses.  We intend to continue the tenant  monitoring  process begun by HRP.
Our tenants will be responsible for the cost of their own Year 2000 compliance.

     The only material issue which we may face from Year 2000 compliance  arises
by reason of possible  delays in  government  Medicare and Medicaid  payments to
certain of our tenants.  In the past, HRP has on one occasion deferred rent from
a tenant when payments under  California's  Medicaid system were delayed because
the  California  legislature  failed to pass a timely  budget.  Based  upon news
reports,  we  understand  that the  federal  and state  governments  are  making
preparations  to avoid delays in Medicare and Medicaid  payments  resulting from
Year 2000 issues. We expect our tenants will make arrangements to pay their rent
obligations in the event of government delays in payments.  Moreover,  we do not
expect  governmental  payment  delays,  if any occur,  to extend  for  prolonged
periods.

Trustees and Executive Officers

     Our  Declaration of Trust provides that a majority of our Board of Trustees
will be Independent  Trustees. An Independent Trustee is a Trustee who is not an
officer  of or  otherwise  affiliated  with  HRP  (so  long  as  HRP  remains  a
shareholder of our Company) or RMR.

     Immediately  after completion of this offering,  our Trustees and executive
officers will be as follows:

Committees of the Board of Trustees

     Promptly following completion of this offering,  the Board of Trustees will
establish an Audit Committee that will consist of our Independent Trustees.  The
Audit  Committee  will  make   recommendations   concerning  the  engagement  of
independent  public  accountants,  review  the  plans and  results  of the audit
engagement,  approve  professional  services provided by the independent  public
accountants,  consider the appropriateness of audit and nonaudit fees charged by
our accountants and review the adequacy of our internal accounting controls.

     The entire Board of Trustees will function as a  Compensation  Committee to
implement our Incentive Share Award Plan described below.

Compensation of the Trustees and Officers

     We will pay our Independent  Trustees an annual fee of $20,000,  plus a fee
of $500 for each meeting attended.  Each Independent  Trustee will automatically
receive  an annual  grant of 500  common  shares  after the  completion  of this
offering and at the first meeting of the Board of Trustees following each annual
meeting  of  shareholders,  commencing  in 2000.  In  addition,  we will pay the
Independent  Trustee serving as Chairman of the Audit Committee $2,000 per year.
This position is expected to rotate annually among the Independent  Trustees. We
will also  reimburse  expenses our Trustees  incur in  attending  meetings.  Our
Managing  Trustees and  officers are  employees of RMR and they will not receive
compensation  directly from us, except reimbursement of expenses and pursuant to
the Incentive Share Award Plan.

Incentive Share Award Plan

     We have adopted an Incentive  Share Award Plan and have reserved  1,000,000
common shares to grant to our Independent  Trustees,  officers and  consultants,
including  selected  employees  of RMR,  but not RMR  itself  which will be paid
pursuant to its contract  described  below.  We have  established  the Incentive
Share  Award  Plan  to  ensure  that  our  officers,  Independent  Trustees  and
shareholders  continue to have similar  interests.  In addition,  the  Incentive
Share Award Plan will permit us to compensate  our officers for the  performance
of certain services and duties in addition to those compensated by RMR.

     As discussed above,  the Independent  Trustees will  automatically  receive
grants of 500 common  shares per year as part of their annual  compensation.  In
granting other incentive share awards, the Board of Trustees intends to consider
a range of factors regarding  potential  grantees,  including the complexity and
duration of tasks performed and the amount and terms of common shares previously
granted.  The vesting  schedule of each incentive share award will be determined
at the time of grant.  No awards will be granted under the Incentive Share Award
Plan before completion of this offering.

Limitation of Liability and Indemnification

     Under our  Declaration of Trust,  our Trustees,  officers and employees are
entitled to indemnification. See "Certain Provisions of Maryland Law and Summary
of the Company's Declaration of Trust and Bylaws" for more information.

exhibit to the registration statement of which this prospectus is a part.

                                       50

     RMR is required to use its best efforts to present us with a continuing and
suitable   investment  program  consistent  with  our  investment  policies  and
objectives. Subject to its duty of overall management and supervision, the Board
of Trustees has delegated to RMR the power and duty to:

     o    provide  research and economic and statistical data in connection with
          our investments and recommend changes in our investment  policies when
          appropriate;

     o    investigate   and   evaluate   investment   opportunities   and   make
          recommendations concerning specific investments to the Trustees;

     o    manage our short-term  investments  including the acquisition and sale
          of money market instruments;

     o    administer  our  day-to-day  operations  including  the leasing of our
          properties and relations with our tenants;

     o    investigate,   negotiate   and  enter   contracts  on  our  behalf  in
          furtherance of our investment activities and objectives;

     o    act as  attorney-in-fact  or agent in acquiring  and  disposing of our
          investments and funds,  and in handling,  prosecuting and settling any
          of our claims;

     o    invest and reinvest any of our money;

     o    monitor our  investments  and all services  provided to us as would be
          done by a prudent owner;

     o    administer such day-to-day bookkeeping and accounting functions as are
          required  for the  management  of our assets,  contract for audits and
          prepare or cause to be prepared such reports as may be required by any
          governmental authority in connection with the conduct of our business;

     o    provide  office space,  office  equipment and the use of accounting or
          computing equipment when required;

     o    provide  personnel  necessary  for the  performance  of the  foregoing
          services; and

     o    upon request by the Trustees,  make reports of its  performance of the
          foregoing services.

     In  performing  its  services  under the  advisory  agreement,  RMR may use
facilities, personnel and support services of various of its affiliates.

     Under the advisory agreement,  RMR assumes no responsibility  other than to
render the services  described  therein in good faith and is not responsible for
any action of the Board of  Trustees in  following  or  declining  to follow any
advice or recommendation  of RMR. In addition,  we have agreed to indemnify RMR,
its  shareholders,   directors,   officers,  employees  and  affiliates  against
liabilities  relating to certain  acts or  omissions  of RMR  undertaken  on our
behalf in good faith.

     The initial  term of the advisory  agreement  expires on December 31, 1999.
Renewals or extensions of the advisory agreement will be subject to the periodic
approval of a majority of the Independent  Trustees.  The advisory agreement can
be terminated by majority vote of the Independent  Trustees upon 60 days' notice
to RMR. Pursuant to the advisory agreement,  RMR and Messrs.  Portnoy and Martin
have  agreed  not to provide  advisory  services  to, or serve as a director  or
officer of, any other REIT which

                                       51
<PAGE>

is  principally  engaged  in  the  business  of  ownership  of  senior  housing,
congregate  communities,  assisted  living or nursing home properties or to make
competitive  direct  investments  in these  types of  properties,  in each case,
without the consent of our Independent Trustees.

     Compensation to RMR. It is intended that the Board of Trustees, acting by a
majority  vote  of the  Independent  Trustees,  will  determine  the  amount  of
compensation  paid to RMR and will determine  whether to renew,  extend or amend
the  advisory  agreement,  in each  case  based  on  such  factors  as it  deems
appropriate. Such factors may include:

     o    the size of the  advisory  fee in relation  to the size,  composition,
          quality and profitability of our investments;

     o    the  success  of  RMR  in  generating   opportunities  that  meet  our
          investment objectives;

     o    the quality and extent of services and advice furnished by RMR;

     o    the rates charged by others performing comparable services; and

     o    the costs of similar services incurred by self-advised REITs.

     The advisory  agreement  currently provides for (1) an annual advisory fee,
payable monthly and reconciled  annually,  and (2) an annual  incentive fee. The
annual advisory fee is equal to the sum of 0.7% of the average  invested capital
up to $250  million,  plus  0.5% of the  average  invested  capital  equal to or
exceeding  $250 million.  "Average  invested  capital"  means the daily weighted
average of the total book value of our 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 reserves for  depreciation or
bad debts or other similar non-cash reserves.  The annual incentive fee is equal
to 15% of the annual  increase in our funds from  operations  (as defined in the
advisory agreement) per share (but in no event more than $.01 per share),  times
the weighted  average  number of shares  outstanding on a fully diluted basis in
each year.  The annual  incentive fees payable to RMR will be paid in our common
shares valued at market value. No incentive fees will be payable for the initial
term of the advisory agreement.

     The  advisory  agreements  currently  in effect  between  RMR and HRP,  and
between RMR and HPT are substantially  similar to the advisory agreement between
RMR and us. Upon  completion of this  offering,  RMR's contract with HRP will be
amended so that HRP's investment in the Company will not be counted for purposes
of determining the advisory fees payable by HRP to RMR.

     We are not  expected  to have  any  employees  or  administrative  officers
separate from RMR.  Services which might otherwise be provided by employees will
be provided to us by employees of RMR. Similarly,  office space will be provided
to us by  RMR.  Although  we do not  expect  to  have  significant  general  and
administrative operating expenses in addition to fees payable to RMR, we will be
required to pay various  other  expenses,  including  the costs and  expenses of
acquiring,  owning  and  disposing  of  our  real  estate  interests  (including
appraisal,  reporting,  audit and legal fees),  the costs of borrowing money and
the costs of securities  listing,  transfer,  registration  and compliance  with
reporting requirements and shareholder  communications generally.  Also, we will
pay the fees of our Independent Trustees.

Legal Proceedings

     We have a limited  operating  history and are not  currently a party to any
legal proceedings.  We are not aware of any material legal proceeding  affecting
our initial  properties  for which we might  become  liable.  Moreover,  HRP has
agreed to indemnify us for any liability affecting any properties transferred to

                                       52
<PAGE>

us or for  which we may  become  liable  as a  result  of  receiving  properties
transferred to us if such liability arose out of an action or inaction by HRP or
an event that occurred before the transfer of the properties to us.

Certain Transactions

     We are  currently a 100% owned  subsidiary  of HRP. Our Managing  Trustees,
Barry M. Portnoy and Gerard M. Martin, also own RMR and act as managing trustees
of HRP. As a result of these relationships,  HRP and Messrs. Portnoy and Martin,
have material  interests in several of the  transactions  that will be completed
simultaneously with this offering:

     o    The 14 Marriott  properties that we currently own will be subjected to
          mortgages  for $250  million  immediately  after the  closing  of this
          offering.  These  mortgage  proceeds  will be  paid to HRP to  satisfy
          intercompany  debt created as part of our formation  transaction.  HRP
          will not be liable for this mortgage debt.

     o    HRP is currently  contractually  bound to purchase the 14 new Marriott
          properties  for $193.8  million.  Upon  completion of this offering we
          will assume HRP's purchase obligation.

     o    Upon  completion  of this  offering  RMR will  become  our  investment
          advisor.  Assuming the  purchase of 14 new  properties  from  Marriott
          pursuant to the contract terms, the pro forma annual advisory fee that
          we will pay to RMR will be $4.6 million. HRP's annual advisory fees to
          RMR will be reduced by approximately the same amount.

     o    Messrs.  Portnoy and Martin will purchase 350,000 of our common shares
          simultaneously with the completion of this offering.  Messrs.  Portnoy
          and Martin will pay the same price per share as public  investors  pay
          in this offering.

   
     o    Upon the  completion  of this  offering,  13.2  million  of our common
          shares will be  distributed  to HRP  shareholders.  We will receive no
          consideration for this distribution.

     o    After  this  offering,  HRP will  retain  13.2  million  of our common
          shares.  By  retaining  these  common  shares,  HRP  will  be  able to
          participate  in  our  future   success   through   distributions   and
          appreciation, if any, in the price of our common shares.
    

                   POLICIES WITH RESPECT TO CERTAIN ACTIVITIES

     The following  discussion  sets forth our policies  regarding  investments,
dispositions,  financings,  conflicts of interest and certain 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 our  shareholders.  We cannot,  however,  change our
policy of seeking to remain  qualified  as a REIT nor can we enter into  certain
extraordinary transactions (such as a merger or the sale of all or substantially
all of our assets) without the approval of two thirds of our shareholders.  Upon
completion of this offering,  HRP will own 35% of our common shares and any such
transaction would likely require HRP's approval.


                                       53
<PAGE>
Investment Policies

     Acquisitions. We will pursue growth by acquiring additional senior housing,
congregate communities,  assisted living properties and nursing homes. In making
future acquisitions, we will consider a range of factors including:

     o    the proposed 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;

     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,  type of  services  provided  and  locations.
However,  we have no policies  which would  limit the  percentage  of our assets
which may be  invested  in any  individual  property  or type of  property or in
properties leased to any single tenant or to an affiliated group of tenants.

     Other  Investments  in Real Estate.  We expect to emphasize  direct  wholly
owned  investments in fee interests.  However,  in certain  circumstances 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
any appreciation in the value of the subject  property.  At all times, we intend
to make our investments  consistent with our continued  qualification  as a REIT
under the Tax Code.

Disposition Policies

     We have no current intention to dispose of any of our initial properties or
other  properties  we  may  acquire.   We  anticipate  that  future  disposition
decisions,  if any,  will be made based on factors  such as the  following:  (1)
potential  opportunities to increase revenues and property values by reinvesting
sale  proceeds;  (2) the  proposed  sale  price;  (3) the  strategic  fit of the
property with the rest of our portfolio; (4) the potential for, or the existence
of, any environmental or regulatory  problems  affecting a particular  property;
(5) the existence of alternative  needs for capital;  and (6) the maintenance of
our qualification as a REIT under the Tax Code.

Financing Policies

     We currently intend to employ conservative financing policies in pursuit of
our growth  strategy.  Although  our  organizational  documents do not limit the
amount of indebtedness we may incur, we

                                       54
<PAGE>

   
currently  intend to  maintain  a capital  structure  in which our debt will not
exceed 50% of our total market  capitalization.  We will consider  future equity
offerings  when,  in our judgment,  doing so will improve our capital  structure
without materially  adversely affecting the market value of our common shares or
impeding our ability to regularly  increase our common share  distribution rate.
We hope to achieve an investment grade rating for our debt  obligations;  but we
do not  expect  that to  happen  until  we have a  successful  track  record  of
operating as an independent public company. Until we achieve an investment grade
rating we expect that the least  costly  debt  capital  available  to us will be
secured debt.  In the future,  we may modify our current  financing  policies in
light of then current  economic  conditions,  relative  costs of debt and equity
capital,  market  values  of  properties,  acquisition  opportunities  and other
factors,  and we may increase or decrease  our  intended  ratio of debt to total
market capitalization accordingly.
    

Conflict of Interest Policies

     Our  Declaration of Trust requires that a majority of our Board of Trustees
be Independent  Trustees who are not affiliated  with RMR or HRP (so long as HRP
remains a shareholder  of our  Company).  In addition,  we have adopted  certain
policies designed to minimize potential  conflicts of interest.  However,  there
can be no assurance that these policies  always will be successful in minimizing
the influences of such  conflicts,  and, if they are not  successful,  decisions
could be made that might not fully serve the interests of all shareholders.

     Our investment advisor, RMR, also acts as the investment advisor to HRP and
HPT, and also has other business interests. As a result, RMR will not be able to
devote all of its business time and  resources to us and  conflicts  could arise
with respect to the  allocation  of its  business  time and  resources.  Messrs.
Portnoy and Martin, our Managing Trustees, are also managing trustees of HRP and
HPT, and each is a director and 50%  shareholder  of RMR. The advisory fees paid
to RMR will be based,  in part,  upon the amount of  investments  which we make.
From 1978  through  March 31,  1997,  Mr.  Portnoy  was a partner in the firm of
Sullivan & Worcester  LLP,  which acts as counsel to us, HRP, HPT, RMR and their
affiliates.  Mr.  Portnoy  receives and will receive  payments  from the firm in
respect of his 1997 retirement which relate in part to fees received by the firm
from us, HRP, HPT, RMR and their affiliates.

     To  address  these  competing  time  demands  and  potential  conflicts  of
interest,  RMR intends that Mr. David Hegarty,  our President,  Chief  Operating
Officer and  Secretary,  and Mr. Ajay Saini,  our Treasurer and Chief  Financial
Officer, will devote substantial amounts of their business time to our business.
In addition,  pursuant to the advisory  agreement,  RMR and Messrs.  Portnoy and
Martin have agreed not to provide advisory services to, or serve as directors or
officers  of, any other REIT which is  principally  engaged in the  business  of
ownership of senior housing, congregate communities,  assisted living properties
or nursing homes or to make  competitive  direct  investments  in these types of
properties,  in each case, without the consent of our Independent  Trustees.  To
promote an identity of economic  interest among our Managing  Trustees,  RMR and
our shareholders, Messrs. Portnoy and Martin will purchase 350,000 common shares
at the same price paid by public  investors in this  offering,  and the advisory
fee will be paid, in part, in our common shares.  Moreover,  the continuation of
the advisory  agreement  and the fees payable to RMR will be subject to periodic
review by our Independent Trustees.  Finally, of course, RMR and Messrs. Portnoy
and Martin are generally  required by applicable  law to act in accordance  with
their fiduciary responsibilities to us.

Policies with Respect to Other Activities

     We intend to operate  in a manner  that will not  subject us to  regulation
under the  Investment  Company Act of 1940. We do not currently  intend:  (1) to
invest in the securities of other issuers for the purpose of exercising  control
over such issuer; (2) to underwrite securities of other issuers; or (3) to trade
actively in loans or other investments.

                                       55
<PAGE>

     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 any  other  securities  we issue and may do so in the
future. The Board of Trustees has no current intention of causing our Company to
repurchase any of the common shares currently offered.  If we were to repurchase
any of the common shares  currently  offered,  we would do so only in conformity
with applicable  federal and state laws and the requirements for qualifying as a
REIT  under  the Tax  Code.  In the  future,  we may  issue  shares or any 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 decide to participate.

                      SUMMARY OF THE TRANSACTION AGREEMENT

     We  have  entered  a  transaction  agreement  with  HRP  (the  "Transaction
Agreement").  The  Transaction  Agreement  sets forth the actions  necessary  to
effect our separation from HRP and governs certain  relations between us and HRP
after the separation.  RMR and Messrs.  Portnoy and Martin will agree to certain
provisions of the  Transaction  Agreement  which affect them. The following is a
summary of the Transaction Agreement.

     Among other matters, the Transaction Agreement provides that:

o    HRP  will  transfer  title  to  84  senior  living  properties  to  certain
     subsidiaries.  The stock of these  subsidiaries will then be transferred to
     us prior to the closing of this offering.

o    At the time the HRP properties  are  transferred to us they will be free of
     mortgage debt, and the leases and mortgages  pertaining to these properties
     will be in full force and effect.

o    Simultaneously with the transfer of properties to us, HRP will assign to us
     its rights to purchase and lease 14 new Marriott properties.

o    As part of the transfer of  properties  and  assignment of the purchase and
     lease agreement from HRP to us, we will assume HRP's obligations  regarding
     the transferred  properties and under the purchase and lease agreement;  we
     will indemnify HRP from future obligations in this regard.

   
o    In partial  consideration of the property  transfers,  we will issue a $250
     million note to HRP.  Immediately after completion of this offering we will
     undertake  a  mortgage  financing  of the 14  Marriott  properties  that we
     acquire from HRP and pay the mortgage proceeds to HRP to satisfy this debt.
     HRP will not be liable for this mortgage debt.

o    Simultaneously  with the completion of this offering,  HRP will  distribute
     13.2 million of our common shares to HRP  shareholders.  This  distribution
     will be paid to HRP  shareholders  on the  basis of one of our  shares  for
     every 10 HRP shares held.  Fractional  shares will not be distributed,  but
     will be paid in cash by HRP at the offering price.
    

o    Simultaneously  with the completion of this offering,  Messrs.  Portnoy and
     Martin will purchase 350,000 of our common shares from us at the same price
     paid by public investors in this offering.

   
o    After the completion of this offering and the  distribution  of our shares,
     HRP will own 13.2  million of our common  shares,  and Messrs.  Portnoy and
     Martin  will  beneficially  own  463,437 of our shares  (including  113,437
     shares as their pro rata distribution to HRP shareholders). HRP and Messrs.
     Portnoy and Martin will agree not to sell or otherwise  transfer any of our
     shares which they own for

                                       56

<PAGE>



     at least one year following completion of this offering unless the proposed
     transfer is approved by vote of our Board of Trustees, including a majority
     of our Independent Trustees.
    

o    HRP will deliver to us all property files and other documentation affecting
     the properties to be transferred to us.

o    Income and expenses of the properties to be transferred will be apportioned
     between us and HRP as of the date of the transfer.

o    HRP will make certain  representations  and  warranties to us regarding its
     knowledge  of the status of the  properties  transferred  to us,  including
     environmental  matters,  and  regarding  the  affected  tenancies  and will
     indemnify us for breaches of its representations and warranties.

   
o    HRP will indemnify us with regard to all liabilities retained by it and any
     litigation or other third party claims affecting the transferred properties
     that  relate  to  activities  that  occur  prior  to the  date  of the  HRP
     distribution or arise by reason of the transfer, if any.

o    Any claim against HRP for breaches of  representation  and  warranties,  or
     otherwise arising from our formation must be asserted within one year after
     the HRP  distribution  and  will  not be  collectable  unless  and  until a
     threshold amount of $1 million is exceeded.
    

o    So long as: (a) HRP remains a shareholder  of our Company,  (b) HRP and our
     Company engage the same investment advisor, or (c) HRP and our Company have
     common  Managing  Trustees:  (1) HRP will not  invest  in  senior  housing,
     congregate communities, assisted living properties or nursing homes without
     the prior approval of our  Independent  Trustees and (2) we will not invest
     in office  properties,  including  medical  office  properties  or clinical
     laboratory  buildings,  without  the prior  approval  of HRP's  independent
     trustees.  In the  event a  particular  investment  involves  both a senior
     living  property and an office  building,  the character of the  investment
     will be determined  according to the majority of the investment  determined
     by appraisal. These non-competition provisions of the Transaction Agreement
     do not apply to  certain  nursing  homes  which HRP will  retain for future
     sale.

o    We  and  HRP  have  agreed  to  cooperate  to  enforce  certain   ownership
     limitations in our respective declarations of trusts in order to facilitate
     compliance  with  certain  provisions  of the Tax  Code  applicable  to our
     respective qualifications as REITs.

o    All disputes between the parties arising under the Transaction Agreement or
     from our formation will be resolved by arbitration.

     Because  the  foregoing  is a  summary  it  may  not  contain  all  of  the
information  about the  Transaction  Agreement  that is important to you. If you
would like more  information  about  these  matters  you should  read the entire
Transaction Agreement, a copy of which has been filed with the SEC as an exhibit
to the registration statement of which this prospectus is a part.

                     CERTAIN PROVISIONS OF MARYLAND LAW AND
                OF THE COMPANY'S DECLARATION OF TRUST AND BY-LAWS

     The following is a summary of certain provisions of Maryland law applicable
to the Company  and the  Declaration  of Trust and the  By-laws of the  Company.
Because it is a summary,  it does not  contain all the  information  that may be
important to you in making an investment decision. If you want more information,
you should read the entire  Declaration of Trust and the By-laws of the Company,
copies  of which  are  exhibits  to the  registration  statement  of which  this
prospectus is a part or refer to the applicable  provisions of the Maryland laws
described herein.

Trustees

     The  By-laws  provide  that the number of  trustees  of the  Company may be
established  by the Board of  Trustees  but may not be fewer than three nor more
than seven. Any vacancy will 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  must be
filled by a majority of the entire Board of Trustees.

     Pursuant to the Declaration of Trust, the Board of Trustees is divided into
three  classes of  trustees.  The initial  terms of the first,  second and third
classes  will expire in 2000,  2001 and 2002,  respectively.  Beginning in 2000,
trustees of each class will be chosen for  three-year  terms upon the expiration
of their  current  terms and each year one class of trustees  will be elected by
the  shareholders.  The Company  believes  that  classification  of the Board of
Trustees  will help to assure the  continuity  and  stability  of the  Company's
business strategies and policies as determined by the Board of Trustees. Holders
of Common  Shares  will have no right to  cumulative  voting in the  election of
trustees. Consequently, at each annual meeting of shareholders, the holders of a
majority of the Common Shares will be able to elect all of the successors of the
class of trustees whose terms expire at that meeting.

     The  classified  board  provision  could  have the  effect  of  making  the
replacement of incumbent  trustees more time  consuming and difficult.  At least
two annual meetings of shareholders,  instead of one, will generally be required
to effect a change in a majority of the Board of Trustees.  Thus, the classified
board  provision  could  increase the likelihood  that  incumbent  trustees will
retain their  positions.  The  staggered  terms of trustees may delay,  defer or
prevent a tender  offer or an attempt to change  control  of the  Company,  even
though a tender offer or change in control  might be in the best interest of the
shareholders.

     Subject  to  the  provisions   described  above  concerning  the  Company's
classified  Board, a majority of the Trustees holding office are required at all
times to be Independent  Trustees. An Independent Trustee is a person who is not
an officer of the Company, of RMR (or a successor investment advisor) or, if HRP
at the time  beneficially  owns  shares of the  Company,  of HRP. If the Company
fails to meet this  requirement  as a result of the creation of a 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,  the application of such  requirement will be suspended
for a period of ninety (90) days.

     The  Declaration  of Trust  provides  that a trustee may be removed with or
without  cause by the  affirmative  vote of at  least  two-thirds  of the  votes
entitled to be cast in the election of trustees.  This  provision,  when coupled
with the  provision  in the  By-laws  authorizing  the Board of Trustees to fill
vacant  trusteeships,  precludes  shareholders from removing  incumbent trustees
except upon a substantial  affirmative vote and filling the vacancies created by
such removal with their own nominees.

Advance Notice of Trustee Nominations and New Business

     The By-laws of the Company  provide that, with respect to an annual meeting
of  shareholders,  nominations  of persons for election to the Board of Trustees
and the proposal of business to be considered by  shareholders  may be made only
(1)  pursuant  to the  Company's  notice  of the  meeting,  (2) by the  Board of
Trustees or (3) by a shareholder  who is entitled to vote at the meeting and has
complied  with the  advance  notice  procedures  set forth in the  By-laws.  The
By-laws also provide  that,  with respect to special  meetings of  shareholders,
only the business  specified in the  Company's  notice of meeting may be brought
before the meeting of  shareholders  and  nominations of persons for election to
the Board of Trustees may be made only (1) pursuant to the  Company's  notice of
the  meeting,  (2) by the Board of  Trustees or (3)  provided  that the Board of
Trustees has  determined  that trustees  shall be elected at such meeting,  by a
shareholder  who is entitled to vote at the  meeting and has  complied  with the
advance notice provisions set forth in the By-laws.

     The advance  notice  provisions of the Company's  By-laws state that, to be
timely, a shareholder's  notice must be delivered to the Company's  Secretary at
the  principal  executive  offices  of the  Company  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.  In the
event that the date of the annual  meeting is  advanced  by more than 30 days or
delayed by more than 60 days from such  anniversary date or if the Trust has not
previously held an annual meeting,  notice by a shareholder 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 the
90th day prior to such  annual  meeting  or the tenth day  following  the day on
which  public  announcement  of the date of such  meeting  is first  made by the
Trust.  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 90 days prior to the first anniversary of the preceding year's
annual meeting, a shareholder's  notice will be considered timely, but only with
respect to nominees for any new  positions  created by such  increase,  if it is
delivered  not later than the close of business on the tenth day  following  the
day on which such  public  announcement  is first made by the Trust.  The public
announcement  of a  postponement  or adjournment of an annual meeting to a later
date  or  time  will  not  commence  a new  time  period  for  the  giving  of a
shareholder's notice.

     Any such notice from a shareholder  of the type  described in the preceding
paragraph  must contain (1) 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,  including  such person's  written  consent to being named in the proxy
statement  as a nominee  and to serving as a Trustee if  elected;  (2) 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 (3) as to the shareholder giving the notice and
the  beneficial  owner,  if any, on whose behalf the  nomination  or proposal is
made,  the name and address of such  shareholder,  as they appear on the Trust's
books,  and of such  beneficial  owner and the number of each class of shares of
the Trust which are owned  beneficially  and of record by such  shareholder  and
such beneficial owner.

     The By-laws provide that at special shareholder meetings, the only business
brought  before the meeting  pursuant to the Company's  notice of meeting may be
conducted.  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 Company's notice of meeting,  (ii) by or at the direction of
the Board of

                                       59
<PAGE>

Trustees or (iii),  provided  that the Board of  Trustees  has  determined  that
Trustees are to 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 and
at the time of the special  meeting,  who is entitled to vote at the meeting and
who has complied with advance notice procedures.  If the Company 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 Company's  notice
of meeting,  if the shareholder's  notice  containing the information  described
above with respect to annual meetings is delivered to the Company's Secretary at
the  principal  executive  offices of the Company 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 the 90th day prior to such special  meeting or
the tenth day  following the day on which public  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.  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.

Liability and Indemnification of Trustees and Officers

     The Maryland REIT statute permits a Maryland real estate  investment  trust
to include in its Declaration of Trust a provision limiting the liability of its
trustees and officers to the trust and its shareholders for money damages except
for liability resulting from (a) actual receipt of an improper benefit or profit
in  money,  property  or  services  or  (b)  active  and  deliberate  dishonesty
established by a final  judgment as being  material to the cause of action.  The
Declaration of Trust of the Company  contains such a provision which  eliminates
such liability to the maximum extent permitted by the Maryland REIT statute.

     The  Declaration  of Trust of the  Company  authorizes  it, to the  maximum
extent  permitted by Maryland law, to obligate itself to indemnify and to pay or
reimburse reasonable expenses in advance of final disposition of a proceeding to
(a) any present or former trustee or officer or (b) any individual  who, while a
trustee of the Company and at the request of the  Company,  serves or has served
another real estate investment trust, corporation,  partnership,  joint venture,
trust,  employee  benefit plan or any other  enterprise as a trustee,  director,
officer  or  partner  of  such  real  estate  investment   trust,   corporation,
partnership,  joint venture,  trust,  employee  benefit plan or 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 or her status as a present or
former  Trustee or officer of the Company.  The By-laws of the Company  obligate
it, to the maximum extent  permitted by Maryland law, to indemnify and to pay or
reimburse reasonable expenses in advance of final disposition of a proceeding to
(a) any  present  or  former  trustee  or  officer  who is  made a party  to the
proceeding by reason of his service in that capacity or (b) any individual  who,
while a trustee or officer of the  Company  and at the  request of the  Company,
serves  or  has  served  another  real  estate  investment  trust,  corporation,
partnership, joint venture, trust, employee benefit plan or any other enterprise
as a trustee, director, officer or partner of such real estate investment trust,
corporation,  partnership,  joint venture, trust, employee benefit plan or other
enterprise and who is made a party to the proceeding by reason of his service in
that capacity,  against any claim or liability to which he may become subject by
reason of such  status.  The  Declaration  of Trust and By-laws  also permit the
Company to indemnify and advance expenses to any person who served a predecessor
of the Company in any of the capacities  described  above and to any employee or
agent of the Company or a predecessor  of the Company.  The By-laws  require the
Company to indemnify a trustee or officer who has been successful, on the merits
or  otherwise,  in the defense of any  proceeding to which he is made a party by
reason of his service in that capacity.

     The Maryland REIT statute permits a Maryland real estate  investment  trust
to indemnify  and advance  expenses to its  trustees,  officers,  employees  and
agents to the same extent as permitted by the

                                       60

<PAGE>

Maryland  General  Corporation  Law,  as amended  ("MGCL"),  for  directors  and
officers of Maryland  corporations.  The MGCL permits a corporation to indemnify
its present and former directors and officers,  among others, against judgments,
penalties,  fines, settlements and reasonable expenses actually incurred by them
in connection with any proceeding to which they may be made a party by reason of
their service in those or other capacities unless it is established that (a) the
act or omission of the  director  or officer was  material to the matter  giving
rise to the proceeding and (i) was committed in bad faith or (ii) was the result
of active and  deliberate  dishonesty,  (b) the  director  or  officer  actually
received an improper  personal benefit in money,  property or services or (c) in
the case of any  criminal  proceeding,  the  director or officer had  reasonable
cause to believe that the act or omission was unlawful. However, under the MGCL,
a Maryland corporation may not indemnify for an adverse judgment in a suit by or
in the right of the corporation or for a judgment of liability on the basis that
personal benefit was improperly  received,  unless in either case a court orders
indemnification  and then only for  expenses.  In  addition,  the MGCL permits a
corporation  to advance  reasonable  expenses to a director or officer  upon the
corporation's receipt of (a) a written affirmation by the director or officer of
his good faith  belief  that he has met the  standard of conduct  necessary  for
indemnification  by the corporation  and (b) a written  undertaking by him or on
his behalf to repay the amount paid or reimbursed by the corporation if it shall
ultimately be determined that the standard of conduct was not met.

     The SEC  has  expressed  the  opinion  that  indemnification  of  trustees,
officers or persons  otherwise  controlling  a company for  liabilities  arising
under the  Securities  Act of 1933, as amended,  is against public policy and is
therefore unenforceable.

Shareholder Liability

     Under the Maryland REIT statute, a shareholder is not personally liable for
the  obligations  of a real estate  investment  trust  solely as a result of his
status  as a  shareholder.  Our  Declaration  of  Trust  also  provides  that no
shareholder shall be liable for any debt, claim, demand,  judgment or obligation
of any kind of,  against or with respect to the Company by reason of his being a
shareholder,  and that no shareholder shall 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  Company by reason of his being a  shareholder.
Despite  these  facts,  counsel  has advised us that in some  jurisdictions  the
possibility  exists that  shareholders  of a trust entity may be held liable for
acts or obligations  of the trust.  While we intend to conduct our business in a
manner designed to minimize potential shareholder liability, no assurance can be
given  that   shareholders   can  avoid   liability  in  all  instances  in  all
jurisdictions.  The Trustees do not intend to provide  insurance  covering these
risks to our shareholders.

Maryland Asset Requirements

     To maintain its  qualification as a Maryland real estate  investment trust,
the Maryland REIT statute  requires that the Company  hold,  either  directly or
indirectly,  at least 75% of the  value of its  assets  in real  estate  assets,
mortgages or mortgage related securities,  government securities,  cash and cash
equivalent items,  including high-grade  short-term  securities and receivables.
The  Maryland  REIT  statute also  prohibits a Maryland  real estate  investment
trust,  such  as  the  Company,   from  using  or  applying  land  for  farming,
agricultural, horticultural or similar purposes.

Transactions with Affiliates, Trustees, Employees, Officers or Agents

     The Declaration of Trust provides that, subject to any express restrictions
adopted by the Trustees in the By-laws or by  resolution,  the Company may enter
into any  contract or  transaction  of any kind 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 Company, whether or not any of them
has a financial interest

                                       61

<PAGE>

in such  transaction.  The  Declaration  of Trust  expressly  provides  that the
Company may engage in a transaction with (a) any Trustee,  officer,  employee or
agent of the  Trust  (acting  in his  individual  capacity),  (b) any  director,
trustee, partner, officer, employee or agent (acting in his individual capacity)
of RMR or any other  investment  advisor  of the  Company,  (c) RMR or any other
investment  advisor of the Company or (d) an affiliate of any of the  foregoing,
provided that such transaction has, after disclosure of such  affiliation,  been
approved or ratified by the  affirmative  vote of a majority of the Trustees not
having any interest in such  transaction  and not affiliates of any party to the
transaction  after a  determination  by them that such  transaction  is fair and
reasonable to the Company and its  shareholders.  The  Declaration of Trust also
provides  that  the  Trustees  may  permit  the  formation  of  a   corporation,
partnership,  trust or other business association owned by any Trustee, officer,
employee or agent or by their  nominees  for the purpose of holding  title to or
managing the Company's  property,  provided that the Trustees determine that the
creation  of such  entity  for  such  purpose  is in the best  interests  of the
Company.

Voting by Shareholders

     Whenever  shareholders  are  required or  permitted to take any action by a
vote at a meeting of  shareholders,  such action may be take only by such a vote
at such a meeting of shareholders, and the shareholders do not have the power or
right to take any action by executing written consents in lieu of such vote.

Restrictions on Transfer of Shares

     The  Declaration  of Trust  restricts the amount of shares that  individual
shareholders may own. These restrictions are intended,  among other purposes, to
assist us in complying with REIT  qualification  restrictions under the Tax Code
and otherwise to promote our orderly governance.

     The  Declaration  of Trust provides that no person may own, or be deemed to
own by virtue of the  attribution  provisions  of the Code,  more than 9.8% (the
"Aggregate  Share  Ownership  Limit") of the number or value of the  outstanding
shares of beneficial  interest of the Company.  In addition,  the Declaration of
Trust  prohibits any person from  acquiring or holding,  directly or indirectly,
common  shares in excess of 9.8% (in value or in number of shares,  whichever is
more restrictive) of the aggregate of the outstanding common shares (the "Common
Share Ownership Limit").

     The  Company's  Board of  Trustees,  in its sole  discretion,  may exempt a
proposed  transferee  from the Aggregate  Share  Ownership  Limit and the Common
Share Ownership Limit (an "Excepted Holder"). It is also a condition to a person
being becoming an Excepted  Holder that he give written notice to the Company no
later than the 15th day before any proposed  transfer  which would result in his
owning shares in excess of Aggregate  Share  Ownership Limit or the Common Share
Ownership Limit. The Board may not grant such an exemption to any person if such
exemption would result in the Company being "closely held" within the meaning of
Section 856(h) of the Tax Code or otherwise  would result in the Company failing
to qualify as a REIT.  In order to be  considered by the Board of Trustees as an
Excepted Holder, a person also must not own, directly or indirectly, an interest
in a tenant of the Company (or a tenant of any entity owned or controlled by the
Company) that would cause the Company to own, directly or indirectly,  more than
a 9.9% interest in such a tenant. The person seeking an exemption must represent
to the  satisfaction of the Board of Trustees that it will not violate these two
restrictions.  The  person  also must  agree  that any  violation  or  attempted
violation  of any of the  foregoing  restrictions  will result in the  automatic
transfer  of the shares of  beneficial  interest  causing  such  violation  to a
charitable trust (as described below).  In determining  whether to grant such an
exemption,  the Board of Trustees may  consider,  among other  factors,  (1) the
general  reputation and moral  character of the person  requesting an exemption,
(2) whether ownership of shares would be direct or through ownership

                                       62

attribution, (3) whether the person's ownership of shares would adversely affect
our  ability to  acquire  additional  senior  housing,  congregate  communities,
assisted living  properties or nursing homes or engage in other business and (4)
whether  granting an exemption  for the person  requesting  an  exemption  would
adversely affect any of our existing contractual arrangements.  In addition, the
Board of Trustees  may require any rulings from the  Internal  Revenue  Service,
opinions of counsel,  affidavits,  undertakings or agreements it deems necessary
or advisable in order to make the foregoing decisions.

   
     The Aggregate Share Ownership Limit and the Common Share Ownership Limit do
not apply to common shares owned, directly or indirectly,  by HRP, RMR and their
affiliates.
    

     The Declaration of Trust further prohibits (a) any person from beneficially
or constructively owning shares of beneficial interest of the Company that would
result in the Company being  "closely  held" under Section 856(h) of the Code or
otherwise cause the Company to fail to qualify as a REIT and (b) any person from
transferring shares of beneficial interest of the Company if such transfer would
result in shares of beneficial interest of the Company being owned by fewer than
100  persons.  Any  person  who  acquires  or  attempts  or  intends  to acquire
beneficial or  constructive  ownership of shares of  beneficial  interest of the
Company  that  will  or  may  violate  any  of  the  foregoing  restrictions  on
transferability and ownership,  or any person who would have owned shares of the
beneficial  interest of the Company that resulted in a transfer of shares to the
Excess Share Trust (as defined below), is required to give notice immediately to
the Company and provide the Company with such other  information  as the Company
may request in order to determine  the effect of such  transfer on the Company's
status as a REIT. The foregoing  restrictions on  transferability  and ownership
will not apply if the Board of Trustees  determines  that it is no longer in the
best interests of the Company to attempt to qualify,  or to continue to qualify,
as a REIT.

   
     If any  transfer of shares of  beneficial  interest  of the Company  occurs
which, if effective,  would result in any person  beneficially or constructively
owning shares of beneficial interest of the Company in excess or in violation of
the above transfer or ownership  limitations (a "Prohibited  Owner"),  then that
number of  shares of  beneficial  interest  of the  Company  the  beneficial  or
constructive  ownership  of which  otherwise  would cause such person to violate
such  limitations  (rounded to the nearest  whole share) (the  "Excess  Shares")
shall be automatically transferred to a trust (the "Excess Share Trust") for the
exclusive  benefit  of one or more  charitable  beneficiaries  (the  "Charitable
Beneficiary"),  and the  Prohibited  Owner  shall not  acquire any rights in the
Excess Shares. Such automatic transfer shall be deemed to be effective as of the
close of business on the Business Day (as defined in the  Declaration  of Trust)
prior to the date of such violative transfer.  Excess Shares shall be issued and
outstanding shares of beneficial  interest of the Company.  The Prohibited Owner
shall not benefit  economically from ownership of any Excess Shares,  shall have
no rights to  distributions  and shall not  possess  any rights to vote or other
rights  attributable to the Excess Shares. The trustee of the Excess Share Trust
(the  "Excess  Share  Trustee")  shall  have all  voting  rights  and  rights to
distributions  with  respect to Excess  Shares held in the Excess  Share  Trust,
which rights  shall be exercised  for the  exclusive  benefit of the  Charitable
Beneficiary.  Any  distribution  paid prior to the discovery by the Company that
shares of beneficial  interest have been transferred to the Excess Share Trustee
shall be paid by the recipient of such  distribution to the Excess Share Trustee
upon demand,  and any distribution  authorized but unpaid shall be paid when due
to the Trustee.  Any  distribution  so paid to the Excess Share Trustee shall be
held in trust for the Charitable Beneficiary. The Prohibited Owner shall have no
voting  rights with respect to shares of  beneficial  interest held in the Trust
and,  subject to  Maryland  law,  effective  as of the date that such  shares of
beneficial  interest have been transferred to the Excess Share Trust, the Excess
Share  Trustee  shall have the  authority  (at the Excess Share  Trustee's  sole
discretion) (1) to rescind as void any vote cast by a Prohibited  Owner prior to
the  discovery  by the Company  that such shares  have been  transferred  to the
Excess Share Trust and (2) to recast such vote in accordance with the desires of
the Excess Share Trustee acting for the benefit of the  Charitable  Beneficiary.
However, if the Company has already taken

                                       63
<PAGE>

irreversible  trust  action,  then the Excess Share  Trustee  shall not have the
authority to rescind and recast such vote.
    

     Within  20 days of  receiving  notice  from  the  Company  that  shares  of
beneficial  interest of the Company  have been  transferred  to the Excess Share
Trust,  the Excess Share Trustee  shall sell the shares of  beneficial  interest
held in the Excess  Share  Trust to a person,  designated  by the  Excess  Share
Trustee,   whose  ownership  of  the  shares  will  not  violate  the  ownership
limitations set forth in the Declaration of Trust.  Upon such sale, the interest
of the Charitable  Beneficiary in the shares sold shall terminate and the Excess
Share Trustee shall  distribute  the net proceeds of the sale to the  Prohibited
Owner and to the Charitable  Beneficiary as follows.  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 Excess Share Trust (e.g., a gift,
devise  or  other  such  transaction),  the  Market  Price  (as  defined  in the
Declaration  of Trust) of such shares on the day of the event causing the shares
to be held in the Excess Share Trust and (2) the price per share received by the
Excess Share  Trustee from the sale or other  disposition  of the shares held in
the Excess Share Trust. Any net sale proceeds in excess of the amount payable to
the Prohibited  Owner shall be paid  immediately to the Charitable  Beneficiary.
If, prior to the  discovery by the Company  that shares of  beneficial  interest
have been  transferred  to the Excess  Share  Trust,  such  shares are sold by a
Prohibited  Owner,  then (1) such  shares  shall be  deemed to have been sold on
behalf of the Excess Share Trust and (2) 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 the aforementioned  requirement,  such
excess shall be paid to the Excess Share Trustee upon demand.

     In  addition,  shares of  beneficial  interest of the  Company  held in the
Excess Share Trust shall be deemed to have been offered for sale to the Company,
or its  designee,  at a price per share equal to the lesser of (1) the price per
share in the  transaction  that  resulted in such  transfer to the Excess  Share
Trust (or, in the case of a devise or gift, the Market Price at the time of such
devise  or gift)  and (2) the  Market  Price on the  date  the  Company,  or its
designee,  accepts such offer.  The Company  shall have the right to accept such
offer until the Excess Share Trustee has sold the shares of beneficial  interest
held in the Excess Share Trust. Upon such a sale to the Company, the interest of
the  Charitable  Beneficiary  in the shares sold shall  terminate and the Excess
Share Trustee shall  distribute  the net proceeds of the sale to the  Prohibited
Owner.

     All certificates  evidencing  common shares will bear a legend referring to
the restrictions described above.

     Every  owner of more than 5% (or such lower  percentage  as required by the
Tax Code or the regulations  promulgated thereunder) of all classes or series of
the Company's common shares,  including common shares,  within 30 days after the
end of each  taxable  year,  is required to give  written  notice to the Company
stating the name and  address of such owner,  the number of shares of each class
and  series of shares of  beneficial  interest  of the  Company  which the owner
beneficially owns and a description of the manner in which such shares are held.
Each such owner shall provide to the Company such additional  information as the
Company may request in order to determine the effect, if any, of such beneficial
ownership on the Company's  status as a REIT and to ensure  compliance  with the
Aggregate  Share  Ownership  Limit and the  Common  Share  Ownership  Limit.  In
addition,  each  stockholder  shall upon  demand be  required  to provide to the
Company such information as the Company may request,  in good faith, in order to
determine the Company's  status as a REIT and to comply with the requirements of
any taxing authority or governmental authority or to determine such compliance.

     The  restrictions  described  above will not preclude the settlement of any
transaction  entered  into  through  the  facilities  of the  NYSE or any  other
national securities exchange or automated inter-dealer

                                       64
<PAGE>

quotation system. The Declaration of Trust provides, however, that the fact that
the settlement of any transaction  occurs shall not negate the effect of any the
foregoing  limitations and any transferee in such a transaction shall be subject
to all of the provisions and limitations described above.

     These ownership  limitations could delay, defer or prevent a transaction or
a change in control of the Company  that might  involve a premium  price for the
common shares or otherwise be in the best interest of the shareholders.

Business Combinations

     Under the MGCL, as applicable  to Maryland real estate  investment  trusts,
certain  "business  combinations"  (including  certain mergers,  consolidations,
share exchanges and asset transfers and certain issuances and  reclassifications
of equity  securities)  between a Maryland real estate  investment trust and any
person who  beneficially  owns ten  percent  or more of the voting  power of the
trust's  shares or an  affiliate  or  associate  (as defined in the MGCL) of the
trust who, at any time within the two-year period prior to the date in question,
was the beneficial  owner of ten percent or more of the voting power of the then
outstanding  voting shares of beneficial  interest of the trust (an  "Interested
Shareholder")  or an affiliate of the Interested  Shareholder are prohibited for
five  years  after  the most  recent  date on which the  Interested  Shareholder
becomes an Interested  Shareholder.  Thereafter,  any such business  combination
must be  recommended  by the board of trustees of such trust and approved by the
affirmative vote of at least (a) 80% of the votes entitled to be cast by holders
of  outstanding  voting  shares  of  beneficial  interest  of the  trust and (b)
two-thirds  of the votes  entitled to be cast by holders of voting shares of the
trust other than shares held by the  Interested  Shareholder  with whom (or with
whose  affiliate  or  associate)  the  business  combination  is to be effected,
unless,  among other  conditions,  the  trust's  common  shareholders  receive a
minimum price (as defined in the MGCL) for their shares and the consideration is
received  in  cash or in the  same  form as  previously  paid by the  Interested
Shareholder for its shares. These provisions of the MGCL do not apply,  however,
to business  combinations that are approved or exempted by the board of trustees
of the  trust  prior to the time  that the  Interested  Shareholder  becomes  an
Interested Shareholder.

     The Board of Trustees of the Company  has adopted a  resolution  that,  any
"business combination" between the Company and any other person is exempted from
the provisions of the MGCL described in the preceding  paragraph,  provided that
such business combination is first approved by the Board of Trustees,  including
the  approval of a majority of the members of the Board of Trustees  who are not
affiliates  or  associates  (as  defined  in the  MGCL)  of  such  person.  Such
resolution,  however,  may be altered or repealed,  in whole or in part,  at any
time by the Board of Trustees of the Trust.

Control Share Acquisitions

     The MGCL, as applicable to Maryland real estate investment trusts, provides
that "control  shares" of a Maryland real estate  investment trust acquired in a
"control share  acquisition" have no voting rights except to the extent approved
by a vote  of  two-thirds  of the  votes  entitled  to be  cast  on the  matter,
excluding shares of beneficial interest owned by the acquiror, by officers or by
trustees who are employees of the trust.  "Control  Shares" are voting shares of
beneficial  interest  which,  if  aggregated  with  all  other  such  shares  of
beneficial interest previously acquired by the acquiror,  or in respect of which
the acquiror is able to exercise or direct the exercise of voting power  (except
solely by virtue of a revocable  proxy),  would entitle the acquiror to exercise
voting power in electing  trustees within one of the following  ranges of voting
power: (1) one-fifth or more but less than one-third,  (2) one-third or more but
less than a  majority,  or (3) a majority or more of all voting  power.  Control
shares do not include shares the acquiring  person is then entitled to vote as a
result of having previously obtained shareholder

                                       65
<PAGE>

approval. A "control share acquisition" means the acquisition of control shares,
subject to certain exceptions.

     A person who has made or proposes to make a control share acquisition, upon
satisfaction of certain  conditions  (including an undertaking to pay expenses),
may  compel  the board of  trustees  of the trust to call a special  meeting  of
shareholders  to be held within 50 days of demand to consider the voting  rights
of the shares. If no request for a meeting is made, the trust may itself present
the question at any shareholders meeting.

     If voting rights are not approved at the meeting or if the acquiring person
does not deliver an acquiring person statement as required by the statute, then,
subject to certain  conditions and limitations,  the trust may redeem any or all
of the control shares (except those for which voting rights have previously been
approved)  for fair value  determined,  without  regard to the absence of voting
rights  for the  control  shares,  as of the  date  of the  last  control  share
acquisition  by the  acquiror  or of any  meeting of  shareholders  at which the
voting rights of such shares are considered  and not approved.  If voting rights
for control  shares are  approved  at a  shareholders  meeting and the  acquiror
becomes  entitled to vote a majority of the shares  entitled to vote,  all other
shareholders  may  exercise  appraisal  rights.  The fair value of the shares as
determined  for  purposes  of such  appraisal  rights  may not be less  than the
highest price per share paid by the acquiror in the control share acquisition.

     The control share acquisition statute does not apply (a) to shares acquired
in a  merger,  consolidation  or share  exchange  if the trust is a party to the
transaction  or (b) to  acquisitions  approved or exempted by a provision in the
declaration  of trust or bylaws of the trust adopted  before the  acquisition of
shares.

     The By-laws of the Company  contain a provision  exempting from the control
share  acquisition  statute  any  and  all  acquisitions  by any  person  of the
Company's  shares of beneficial  interest.  There can be no assurance  that such
provision will not be amended or eliminated at any time in the future.

Amendment to the Declaration of Trust

     The Declaration of Trust, including its provisions on classification of the
Board  of  Trustees  and  removal  of  trustees,  may  be  amended  only  by the
affirmative  vote of the holders of not less than two thirds of all of the votes
entitled to be cast on the  matter.  Under the  Maryland  REIT  statute,  a real
estate  investment  trust generally  cannot  dissolve,  amend its declaration of
trust or merge, unless approved by the affirmative vote of shareholders  holding
at least two-thirds of the shares entitled to vote on the matter unless a lesser
percentage (but not less than a majority of all of the votes entitled to be cast
on the matter) is set forth in the real estate investment trust's declaration of
trust.  The  Company's  Declaration  of  Trust  does  not  provide  for a lesser
percentage in such situations. Under the Maryland REIT statute, a declaration of
trust may permit the trustees by a two-thirds  vote to amend the  declaration of
trust from time to time to qualify as a real estate  investment  trust under the
Code or the  Maryland  REIT  statute  without  the  affirmative  vote or written
consent of the  shareholders.  The Company's  Declaration  of Trust permits such
action by the Board of Trustees.

Dissolution of the Company

     Pursuant to the Company's  Declaration  of Trust,  the  dissolution  of the
Company  must be approved by a majority of the entire  Board of Trustees  and by
the  affirmative  vote of the  holders of not less than two thirds of all of the
votes entitled to be cast on the matter.

Anti-takeover   Effect  of  Certain  Provisions  of  Maryland  Law  and  of  the
Declaration of Trust and By-laws

     The business combination provisions and, if the applicable provision in the
By-laws is rescinded,  the control share acquisition provisions of the MGCL, the
provisions  of the  Declaration  of  Trust  on  classification  of the  Board of
Trustees  and  removal of  trustees  and the advance  notice  provisions  of the
By-laws could delay,  defer or prevent a  transaction  or a change in control of
the Company that might  involve a premium  price for holders of common shares or
otherwise be in their best interest.

                          DESCRIPTION OF THE SECURITIES

     The  following  is a  summary  of the  terms of the  shares  of  beneficial
interest of the  Company.  Because it is a summary,  it does not contain all the
information  that may be important to you in making an investment  decision.  If
you want more information,  you should read the entire  Declaration of Trust and
the By-laws of the  Company,  copies of which are  exhibits to the  registration
statement of which this prospectus is a part.

General

   
     The  Declaration  of Trust  provides  that the  Company  may issue up to 50
million shares of beneficial  interest,  $.01 par value per share,  all of which
have been classified as common shares.  Upon completion of this offering and the
concurrent offering to Messrs. Martin and Portnoy, 37,624,760 common shares will
be issued and outstanding.

     As  permitted  by the  Maryland  REIT  statute,  the  Declaration  of Trust
contains a provision permitting the Board of Trustees, without any action by the
shareholders  of the Company,  to amend the  Declaration of Trust to increase or
decrease the aggregate number of shares of beneficial  interest or the number of
shares of any  class of  shares of  beneficial  interest  that the  Company  has
authority  to issue.  The  Declaration  of Trust  also  authorizes  the Board of
Trustees to  reclassify  any  unissued  shares  into other  classes or series of
classes of beneficial  interest  (including a reclassification  of common shares
into  preferred  shares and of  preferred  shares  into common  shares),  and to
establish  the  number  of  shares  in  each  class  or  series  and to set  the
preferences,   conversion  and  other  rights,   voting  powers,   restrictions,
limitations  as to  distributions,  qualifications  or  terms or  conditions  of
redemption for each such class or series.
    

Common Shares

   
     All common shares  offered hereby will be duly  authorized,  fully paid and
nonassessable.  Subject to the preferential  rights of any other class or series
of  beneficial  interest  and to the  provisions  of the  Declaration  of  Trust
regarding  the  restriction  of the transfer of shares of  beneficial  interest,
holders of common  shares are entitled to receive  distributions  on such shares
if, as and when  authorized and declared by the Board of Trustees of the Company
out of assets legally  available  therefor and to share ratably in the assets of
the Company legally  available for distribution to its shareholders in the event
of its  liquidation,  dissolution  or  winding up after  payment of or  adequate
provision for all known debts and liabilities of the Company.

     Subject  to the  provisions  of the  Declaration  of  Trust  regarding  the
restriction of the transfer of shares of beneficial  interest,  each outstanding
common share entitles the holder to one vote on all matters  submitted to a vote
of  shareholders,  including the election of trustees,  and,  except as provided
with

                                       67
<PAGE>

respect to any other class or series of shares,  the holders of such shares will
possess  the  exclusive  voting  power.  There is no  cumulative  voting  in the
election  of  trustees,  which  means  that the  holders  of a  majority  of the
outstanding  common  shares  can elect all of the  trustees  then  standing  for
election and the holders of the  remaining  shares will not be able to elect any
trustees.

     Holders of common shares have no preference,  conversion, exchange, sinking
fund,  redemption or (subject to the listing of the common shares on the NYSE or
another  national  securities  exchange or its  designation as a national market
security on NASDAQ)  appraisal rights and have no preemptive rights to subscribe
for any securities of the Company.  Subject to the provisions of the Declaration
of Trust regarding the restriction on transfer of shares of beneficial interest,
common shares will have equal distribution, liquidation and other rights.
    

     Under the Maryland REIT statute,  a Maryland real estate  investment  trust
generally  cannot  dissolve,  amend its  declaration  of trust or merge,  unless
approved by the affirmative vote of shareholders  holding at least two thirds of
the shares  entitled to vote on the matter unless a lesser  percentage  (but not
less than a majority  of all of the votes  entitled to be cast on the matter) is
set forth in the trust's  Declaration of Trust.  The Declaration of Trust of the
Company does not provide for a lesser  percentage in such situations.  Under the
Maryland  REIT  statute,  a  declaration  of trust may permit the  trustees by a
two-thirds  vote to amend the  declaration of trust from time to time to qualify
as a REIT under the Code or the Maryland  REIT statute  without the  affirmative
vote or written consent of the shareholders.  The Company's Declaration of Trust
permits such action by the Board of Trustees.

Power to Issue Additional Common Shares

   
     The  Company  believes  that the  power of the Board of  Trustees  to issue
additional  authorized but unissued  common shares and to classify or reclassify
unissued  shares and thereafter to cause the Company to issue such classified or
reclassified  shares of  beneficial  interest  will  provide  the  Company  with
increased flexibility in structuring possible future financings and acquisitions
and in meeting other needs which might arise. The additional  classes or series,
as well as the common  shares,  will be available for issuance  without  further
action  by the  Company's  shareholders,  unless  such  action  is  required  by
applicable law or the rules of any stock exchange or automated  quotation system
on which the Company's securities may be listed or traded. Although the Board of
Trustees has no  intention  at the present time of doing so, it could  authorize
the Company to issue a class or series that could,  depending  upon the terms of
such  class or series,  delay,  defer or  prevent a  transaction  or a change in
control of the Company that might  involve a premium price for holders of common
shares or otherwise be in their best interest.
    

Restriction on Transfer of Shares

   
     The  Declaration of Trust provides  certain  restrictions  on the amount of
shares which individual  shareholders may own. Those  restrictions are described
above under the caption "Certain Provisions of Maryland Law and of the Company's
Declaration of Trust and By-laws".

                        FEDERAL INCOME TAX CONSIDERATIONS

     The following  discussion of federal income tax  considerations is based on
existing  law,  is limited to  investors  who will hold our common  shares as an
investment  asset  (rather than as  inventory or as property  used in a trade or
business),  is not exhaustive of all possible tax  considerations,  and does not
discuss any state,  local,  or foreign  tax  considerations.  Additionally,  the
following 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 a life  insurance  company,  a regulated  investment
company,  a financial  institution,  a broker or dealer in securities or foreign
currency,  a person that has a functional currency other than the U.S. dollar, a
person  who  acquires  common  shares or options  to  acquire  common  shares in
connection  with their  employment or other  performance  of services,  a person
subject to alternative  minimum tax, a person who holds common shares as part of
a  straddle,  hedging  transaction,  or  conversion  transaction  or,  except as
specifically  described  in the  following  summary,  a  tax-exempt  entity or a
foreign person.

     The  sections  of  the  Tax  Code  that  govern  the  federal   income  tax
qualification  and treatment of a REIT and its shareholders are highly technical
and  complex.  The  following  summary is thus  qualified in its entirety by the
applicable Tax Code provisions, the rules and regulations promulgated under such
Tax Code provisions,  and the administrative and judicial interpretations of the
Tax Code and its rules and  regulations,  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.  In  addition,  no ruling  has been  sought  from the IRS with
respect to any matter  described in this summary,  and there can be no assurance
that the IRS or a court  will agree with the  statements  made in this  summary.
Accordingly,  we urge you to consult  your own tax advisor  with  respect to the
federal income tax and other tax consequences of the purchase,  holding and sale
of our common shares.

Taxation as a REIT

     We will elect to be taxed as a REIT under  Sections  856 through 860 of the
Tax Code,  commencing with our initial taxable year ending December 31, 1999. To
qualify as a REIT,  we must also meet other  requirements,  which are  discussed
below. Our REIT election, assuming continuing compliance with the federal income
tax qualification tests summarized below, will continue in effect for subsequent
taxable years.

     We believe  that we will be  organized  and will  operate in a manner  that
qualifies  us to be  taxed  under  the Tax  Code as a REIT  commencing  with our
initial  taxable year ending  December  31,  1999,  and we intend to continue to
operate in a manner to so qualify. No assurance can be given,  however, that the
manner  in which we will  operate  will  qualify  us to be taxed as a REIT.  For
periods  ending on or before the date we cease to be wholly owned by HRP, we and
our  subsidiaries  were at all times  qualified REIT  subsidiaries  of HRP under
Section 856(i) of the Tax Code (or equivalently, noncorporate entities that were
part of HRP pursuant to  regulations  under  Section 7701 of the Tax Code),  and
thus during such periods we and our  subsidiaries  were not  taxpayers  separate
from HRP for federal income tax purposes.  Instead,  pursuant to the Transaction
Agreement,  the federal income tax liabilities and federal income tax filings in
respect of our and our  subsidiaries'  operations and assets through the date we
cease to be wholly owned by HRP are solely the responsibility of HRP.

     We have obtained a legal opinion from our counsel  Sullivan & Worcester LLP
that  we  have  been  organized  in  conformity   with  the   requirements   for
qualification  as a REIT under the Tax Code  commencing  with our  taxable  year
ending  December 31, 1999 and that our current and  anticipated  investments and
our plan of operation  will enable us to continue to meet the  requirements  for
qualification  and  taxation  as a REIT  under the Tax  Code.  This  opinion  is
conditioned upon the

                                       70
<PAGE>

assumption that our leases, our Declaration of Trust and By-laws,  and all other
legal  documents  to which  we are or have  been a party  have  been and will be
complied  with  by  all  parties  to  such  documents,  upon  the  accuracy  and
completeness  of the factual  matters  described  in this  prospectus,  and upon
representations  made  by us as to  certain  factual  matters  relating  to  our
organization  and operations and our expected manner of operation.  In addition,
the opinion of Sullivan & Worcester  LLP is based on the law as it exists today,
but the law may change in the future, possibly with retroactive effect. Also, an
opinion of counsel is not binding on either the  Internal  Revenue  Service or a
court,  and  the  IRS or a court  could  take a  position  different  from  that
expressed by counsel.

     Our  actual  qualification  and  taxation  as a REIT will  depend  upon our
ability to meet on a continuing basis (through actual operating  results,  asset
composition,  distribution  levels and diversity of stock ownership) the various
REIT qualification  tests imposed under the Tax Code and summarized below. While
we have  represented  that we  plan to  operate  in a  manner  to  satisfy  on a
continuing basis the various REIT qualification tests,  Sullivan & Worcester LLP
has not  reviewed  and will not review  our  compliance  with  these  tests on a
continuing  basis, and thus no assurance can be given that we will satisfy 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  in the  same  manner  as  shareholders  of
ordinary  corporations.  In such an event,  we could be subject  to  potentially
significant  tax  liabilities,  and therefore  the amount of cash  available for
distribution to our shareholders would be reduced or eliminated.

     If we qualify for taxation as a REIT and distribute to our  shareholders at
least 95% of our "real estate  investment  trust  taxable  income"  (computed by
excluding any net capital gain and before taking into account any dividends paid
deduction  for which we are  eligible),  we  generally  will not be  subject  to
federal  corporate  income taxes on the amount  distributed.  This deduction for
dividends  paid to  shareholders  substantially  eliminates  the federal  double
taxation on corporate  earnings  (once at the  corporate  level and again at the
shareholder level upon a dividend  distribution)  that generally results from an
investment in an ordinary corporation.

     However,  even if we qualify for federal income  taxation as a REIT, we may
be subject to federal tax in certain 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   Under  certain  circumstances,  we may  be  subject  to  the  corporate
         alternative minimum tax on our items of tax preference, if any.

     o   If we have  (1) net  income  from  the  sale or  other  disposition  of
         "foreclosure  property"  (generally,  property  acquired  by us through
         foreclosure  or  otherwise  after a default  on a loan  secured  by the
         property or on a lease of the property) that is held primarily for sale
         to  customers  in  the  ordinary   course  of  business  or  (2)  other
         nonqualifying income from foreclosure property, then we will be subject
         to tax on such income at the highest regular  corporate rate (currently
         35%).

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

     o   If we should fail to satisfy the 75% gross income test or the 95% gross
         income  test  (both of which  are  discussed  below),  but  nonetheless
         maintain our qualification as a REIT because certain other requirements
         are met, we will be subject to tax at a 100% rate on the greater of the
         amount

                                       71
<PAGE>

         by which  we fail the 75% or the 95%  test,  multiplied  by a  fraction
         intended to reflect our profitability.

     o   If we should fail to distribute  for any calendar year at least the sum
         of (1) 85% of our REIT  ordinary  income for that year,  (2) 95% of our
         REIT capital gain net income for that year,  and (3) any  undistributed
         taxable  income  from  prior  periods,  then 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 any asset from a C corporation (generally,  a corporation
         subject  to full  corporate  level tax) in a  transaction  in which our
         basis in the asset is determined by reference to the basis of the asset
         in the hands of the C  corporation,  and if we  subsequently  recognize
         gain on the  disposition  of such  asset  during  the  ten-year  period
         beginning  on the date on which the asset was  acquired  by us, then we
         will pay tax at the highest regular  corporate tax rate (currently 35%)
         on the lesser of (1) the excess of the fair  market  value of the asset
         over our basis in the asset on the date acquired by us and (2) the gain
         recognized by us in the disposition.

     If we should invest in properties  in foreign  countries,  our profits from
such  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 satisfy the
annual distribution  requirements for federal income tax qualification as a REIT
and are therefore not subject to federal corporate income tax on that portion of
our  ordinary  income and  capital  gain that is  currently  distributed  to our
shareholders,  we will  generally not be able to recover the cost of any foreign
tax imposed on profits  from our  foreign  investments  by claiming  foreign tax
credits against our federal income tax liability on those profits.  Moreover, as
a REIT under the Tax Code, we will be unable to 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, and any potentially  applicable  relief  provisions do not apply,  then we
will be subject to tax on our taxable  income at regular  corporate  rates (plus
any  applicable  corporate  alternative  minimum  tax).   Distributions  to  our
shareholders  in any  year in  which we fail to  qualify  as a REIT  will not be
deductible by us, 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 certain  limitations  in the Tax Code will be  eligible  for the
dividends received  deduction for corporations.  Unless entitled to relief under
specific statutory provisions,  we will also be disqualified from federal income
taxation as a REIT for the following four taxable  years.  It is not possible to
state whether in all circumstances we would be entitled to statutory relief from
such  disqualification.  Also, failure to qualify for even one year could result
in  our  incurring  substantial  indebtedness  (to  the  extent  borrowings  are
feasible) or liquidating  substantial  investments in order to pay the resulting
corporate- level taxes.

REIT Qualification Requirements

     General  Requirements.  Section  856(a) of the Tax 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 common
          shares or by transferable certificates of beneficial interest;


                                       72

<PAGE>

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

     (4)  that is  neither a  financial  institution  nor an  insurance  company
          subject to certain special provisions of the Tax Code;

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

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

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

Section 856(b) of the Tax 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
proportionate  part of a taxable year of less than 12 months. We believe that we
will satisfy conditions (1) to (4),  inclusive,  at all times during our taxable
year ending  December  31,  1999,  and that we will  continue  to satisfy  those
conditions at all times  thereafter.  We also believe that we will have at least
100  shareholders  during the  requisite  period for each of our  taxable  years
commencing with our taxable year ending December 31, 1999.  There can,  however,
be no assurance in this regard.  If we have fewer than 100  shareholders  during
the requisite period,  then condition (5) described above will not be satisfied,
and we would not qualify as a REIT during that taxable year.

     By  reason of the  "closely  held"  condition  (6)  above,  we will fail to
qualify as a REIT for a taxable year if at any time during the last half of such
year more than 50% in value of our  outstanding  common shares is owned directly
or indirectly by five or fewer  individuals.  To help comply with condition (6),
our Declaration of Trust contains certain  provisions  restricting  transfers of
our common  shares and giving the Trustees the power to redeem our common shares
involuntarily;   similarly,   for  the  purpose  of  HRP   maintaining  its  own
qualification as a REIT under the Tax Code, HRP's  declaration of trust contains
similar provisions that limit concentrated  ownership of beneficial interests in
HRP.  In  addition,  if we  comply  with  applicable  Treasury  regulations  for
ascertaining the ownership of our outstanding  common shares and do not know (or
exercising  reasonable  diligence  would  not  have  known)  whether  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  common  shares may result in a penalty of $25,000
($50,000 for  intentional  violations).  Accordingly,  we will comply with these
applicable  Treasury  regulations,  and request  annually from record holders of
certain  significant  percentages  of  our  common  shares  certain  information
regarding the ownership of our common  shares.  Under our  Declaration of Trust,
our shareholders are required to respond to these requests for information.

     The rule that an entity  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 its
outstanding  common  shares is owned  directly  or  indirectly  by five or fewer
individuals  is relaxed  in the case of certain  pension  trusts  owning  common
shares in a REIT. Common 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 the REIT is a  "pension-held  REIT," each pension trust
holding more than 10% of the REIT's common 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.

                                       73
<PAGE>

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

     Our Investments through Partnerships.  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 Tax 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 such  partnership  and is deemed to be entitled to the income of the
partnership  attributable to such  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 are  treated as our assets,  liabilities,
and items of income 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 Section 701 et seq. of the Tax Code.

   
     Income  Tests.  There are two gross income  requirements  applicable to our
Company.  First, at least 75% of our gross income  (excluding  gross income from
certain sales of property held  primarily for sale) must be derived  directly or
indirectly from  investments  relating to real property  (including  "rents from
real property" as defined under Section 856 of the Tax Code),  mortgages on real
property,  or common  shares in other  REITs.  When we  receive  new  capital in
exchange for our common shares (other than distribution reinvestment amounts) or
in  a  public  offering  of  five-year  or  longer  debt   instruments,   income
attributable to the temporary  investment of such new capital in stock or a debt
instrument,  if  received  or accrued  within one year of our receipt of the new
capital,  is also qualifying income under the 75% test.  Second, at least 95% of
our gross income  (excluding  gross income from certain  sales of property  held
primarily  for sale) must be derived  from a  combination  of (1) real  property
investments that satisfy the 75% test, (2) dividends,  (3) interest, (4) certain
payments under interest rate swap or cap agreements, options, futures contracts,
forward rate agreements, or similar financial instruments, and (5) gain from the
sale or disposition  of stock,  securities,  or real  property.  For purposes of
these  two gross  income  rules,  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.  We may  temporarily  invest  working
capital in  short-term  investments,  including  common  shares in other  REITs.
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
Tax Code,  several  requirements must be met. First, the amount of rent received
generally must not be determined  from the income or profits of any person,  but
may be based on receipts or sales.  Second,  the Tax Code provides that rents do
not  qualify if the REIT owns 10% or more of the  tenant,  whether  directly  or
after  application of certain  attribution  rules.  While we intend not to lease
property to any party if rents from

                                       74
<PAGE>

that property would not qualify as rents from real property under Section 856 of
the Tax Code,  application  of the 10% ownership  rule is dependent upon complex
attribution rules including  circumstances  that may be beyond our control.  For
example,  ownership  (directly or by attribution) by an unaffiliated third party
of more than 10% of our  common  shares and more than 10% of the stock of one of
our lessees  would result in such lessee's  rents not  qualifying as "rents from
real  property."  Our  Declaration of Trust provides that transfers or purported
acquisitions,  directly or by attribution, of common shares that could result in
our  disqualification as a REIT under the Tax Code are null and void and permits
the Trustees to repurchase common shares to the extent necessary to maintain our
status  as a REIT  under  the  Tax  Code.  Similarly,  for  the  purpose  of HRP
maintaining  its  own  qualification  as  a  REIT  under  the  Tax  Code,  HRP's
declaration of trust contains  provisions that limit  concentrated  ownership of
beneficial  interests in HRP.  Furthermore,  the Transaction  Agreement provides
that HRP will not acquire  more than 9.8% of the equity in any of our tenants or
take other actions that may  jeopardize  our REIT status under the Tax Code, for
so long as HRP owns more than 9.8% of our common stock. Nevertheless,  there can
be no assurance that such provisions in our and HRP's  declarations of trust and
in the Transaction  Agreement will be effective to prevent our REIT status under
the Tax 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 shareholders  necessarily be aware of
shareholdings  attributed to them under the Tax Code's attribution rules. Third,
in order for its rents to qualify as "rents from real  property"  under  Section
856 of the Tax Code,  we  generally  must not manage the  property or furnish or
render  services to the tenants of such property,  except through an independent
contractor  from whom we derive no income.  There is an  exception  to this rule
permitting a REIT to perform certain 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 Tax
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 of the property.
Fourth,  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 such rent  attributable to personal property will qualify as "rents
from real property" under Section 856 of the Tax Code; but 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 property  (both real and  personal)  which is rented.
Substantially  all of our gross income is expected to be  attributable to rental
income.  We believe  that all or  substantially  all our rents  will  qualify as
"rents from real  property" for purposes of Section 856 of the Tax Code,  but if
for some reason a significant  amount of our rents do not so qualify,  it may be
difficult or impossible  for us to meet the 95% or 75% gross income tests and to
qualify as a REIT for federal income tax purposes.

     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 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.

     Any gain  realized by us 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.  Under  existing law,  whether
property is held as inventory or primarily for sale to customers in the ordinary
course of a trade or  business  is a  question  of fact that  depends on all the
facts and circumstances with respect to the particular transaction. We intend to
(1) hold our real estate assets for investment  with a view to long-term  income
production and capital appreciation, (2) engage in

                                       75
<PAGE>

the business of developing, owning and operating our existing real estate assets
and acquiring,  developing,  owning and operating other real estate assets,  and
(3) make occasional dispositions of real estate assets as is consistent with our
investment objectives. We believe that any occasional disposition of real estate
that we might make will not be subject to the 100%  penalty  tax. But because of
the highly  factual nature of the inquiry,  we cannot  provide  assurances as to
whether  or not  the  IRS  might  successfully  assert  that  one or more of our
occasional dispositions is subject to the 100% penalty tax.

     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 (1) our
failure  to meet the test was due to  reasonable  cause  and not due to  willful
neglect,  (2) we  reported  the  nature  and  amount of each item of our  income
included  in the 75% or 95%  gross  income  tests  (as the case may be) for that
taxable  year on a schedule  attached to our tax return,  and (3) any  incorrect
information on the schedule was not due to fraud with intent to evade tax. 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.  As
discussed  above,  even if this relief  provision did apply to us, 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. First,
at least 75% of the value of our total assets must consist of real estate assets
(which for this purpose  includes  stock or debt  instruments  held for not more
than one year  purchased  with  proceeds of a stock  offering or a long-term (at
least five years) debt  offering of ours),  cash,  cash items,  common shares in
other REITs, and government  securities.  Second, 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).  Third,  of the  investments
included  in the  preceding  25%  asset  class,  the  value of any one  issuer's
securities  owned by us may not exceed 5% of the value of our total assets,  and
we may not own more than 10% of any one issuer's  outstanding voting 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 Tax Code,  we are  required  to make  distributions  (other  than
capital  gain  dividends)  to our  shareholders  each year in an amount at least
equal to the  excess  of (A) the sum of (1) 95% of our "real  estate  investment
trust taxable  income" (as defined in Section 857 of the Tax Code,  but computed
without regard to the dividends paid deduction and net capital gain) and (2) 95%
of our net income  (after  tax),  if any,  from  certain  property  received  in
foreclosure,  over (B) the sum of certain noncash income of ours (e.g.,  certain
imputed rental income or certain income from transactions  inadvertently failing
to qualify  as  like-kind  exchanges).  Such  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.  Also,
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. A  distribution  which is not pro rata within a class of beneficial
interests in our Company entitled to a distribution,  or which is not consistent
with the rights to distributions  between classes of beneficial interests in our
Company, is a preferential distribution that is not taken into consideration for
purposes  of the  distribution  requirement,  and  accordingly  the payment of a
preferential  distribution  could  affect our  ability to meet the  distribution
requirement.  Taking  into  account our  distribution  policies  (including  any
dividend  reinvestment  plan we may adopt), we expect that we will never pay 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 distribution
previously made to meet the

                                       76
<PAGE>
requirements of the 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.

     It is possible  that from time to time we may not have  sufficient  cash or
other  liquid  assets to meet the 95%  distribution  requirements  due to timing
differences  between (1) the actual  receipt of income and the actual payment of
deductible  expenses or  distributions  and (2) the  inclusion of income and the
deduction of expenses or distributions  in computing our real estate  investment
trust  taxable  income.   The  problem  of  inadequate  cash  to  make  required
distributions could also occur as a result of the repayment in cash of principal
amounts  due on our  outstanding  debt,  particularly  in the  case  of  balloon
repayments or as a result of capital losses on short-term investments of working
capital.  In any of these  circumstances,  we might find it necessary to arrange
for short-term or possibly long-term borrowing,  or for new 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 such
borrowing or financing  would be  available  for these  purposes or available on
favorable terms.

     Under  certain  circumstances,  we may be able to rectify a failure to meet
the  distribution  requirement  for a year by paying  "deficiency  dividends" to
shareholders  in a later  year,  which  may be  included  in our  deduction  for
dividends  paid for the  earlier  year,  although 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 may in certain
such circumstances remain liable for the 4% excise tax discussed above.

Federal Income Tax Treatment of Leases

     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,
and if the  leases of the  facilities  are  classified  for  federal  income tax
purposes as true leases, rather than as sales or financing  arrangements.  As to
approximately  five to ten  percent of our leased  facilities  which  constitute
personal property, it is not entirely clear that we will be treated as the owner
of such  personal  property  and that the leases  will be treated as true leases
with respect to such  property.  We plan to ensure our  compliance  with the 95%
distribution requirements (and the excise tax required distribution requirement)
by  making  distributions  on  the  assumption  that  we  are  not  entitled  to
depreciation   deductions  for  the  portion  of  our  leased  facilities  which
constitute  personal  property,  but to perform all our tax  reporting by taking
into account personal property depreciation.

      In the case of certain 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  exceeds the purchase  price paid by us for
that  property.   In  litigated  cases  involving   sale-leasebacks  which  have
considered this issue,  courts have concluded that buyers have realized  prepaid
rent where both parties  acknowledged that the purported  purchase price for the
property was  substantially  less than fair market value and the purported rents
were substantially less than the fair market rentals. Because of the lack of

                                       77
<PAGE>

clear precedent, we cannot provide assurances as to whether or not the IRS might
successfully assert the existence of prepaid rental income.

   
     Additionally,   Section  467  of  the  Tax  Code  (concerning  leases  with
increasing  rents) may apply to certain of our leases  because  they provide for
rents that  increase  from one period to the next.  Section  467 of the Tax 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  95%  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. Because Section 467 of the Tax Code directs
the Treasury to issue  regulations  providing  that rents will not be treated as
increasing for tax avoidance purposes where the increases are based upon a fixed
percentage of lessee receipts,  and because regulations proposed to be effective
for "disqualified  leaseback  agreements"  entered into after June 3, 1996 adopt
this rule,  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." In addition,  the legislative  history of
Section 467 of the Tax Code indicates that the Treasury should issue regulations
under  which  leases  providing  for  fluctuations  in rents  by no more  than a
reasonable  percentage  from the average rent payable over the term of the lease
will be deemed not  motivated by tax  avoidance,  and the  proposed  regulations
permit a 10% fluctuation.
    

Depreciation of Properties

   
     For federal  income tax  purposes,  including for purposes of computing our
earnings and profits (which computation  affects the amount of our distributions
that are taxable as dividends to our  shareholders,  as described in  subsequent
sections of this  summary),  our  depreciation  deductions for the properties we
owned while we were still a wholly owned  subsidiary  of HRP will be as follows.
Under one  interpretation  of applicable  Tax Code  provisions,  our initial tax
basis in these  properties will be their fair market value  determined as of the
date  we  cease  to  be  wholly  owned  by  HRP.  However,  under  an  alternate
interpretation of these applicable Tax Code provisions, our initial tax basis in
these properties will be the lesser of (1) this fair market value or (2) the sum
of (A) the  adjusted tax basis in the  properties  while we were still a part of
HRP for federal  income tax purposes,  and (B) the then  outstanding  balance of
principal and accrued  interest on the $250 million loan owed by us to HRP. Even
if this  alternate  interpretation  of the  applicable  Tax Code  provisions  is
correct,  we anticipate that the fair market value of the subject  properties on
the  relevant  date would be less than the  amount  described  in the  preceding
clause (2), so that our initial tax basis in these properties would in any event
be their fair market value determined as of the date we cease to be wholly owned
by HRP.  Because of the  factual  nature of  valuation  issues,  our tax counsel
Sullivan & Worcester LLP is not rendering an opinion on the fair market value of
our properties on the date we cease to be wholly owned by HRP.
    

     Assuming  that  the  first   interpretation  of  the  applicable  Tax  Code
provisions  described in the preceding paragraph is correct, we should generally
depreciate the initial fair market value tax basis of the subject  properties on
a straight-line basis over 40 years with respect to the realty and over 12 years
with respect to the personalty.  In contrast, if the alternate interpretation of
these applicable Tax Code provisions is correct,  then we should  depreciate the
tax basis in the subject properties in a bifurcated manner: (1) to the extent of
the adjusted tax basis in these properties while we were still a part of HRP for
federal income tax purposes,  we should  generally  carry over the  depreciation
methodology then in use (generally  straight-line) over the years then remaining
in the depreciation periods for these properties (which would generally be fewer
than 40 years for the realty and fewer than 12 years for the  personalty),  plus
(2) as to any increment in our tax basis in these  properties as a result of our
ceasing to be wholly owned by HRP, depreciation of the increment would generally
be on a straight-line basis over 40 years with respect to the realty and over 12
years with respect to the personalty. In general, as compared to the

                                       78

<PAGE>

first  possible  interpretation  of the  applicable  Tax  Code  provisions,  the
alternate interpretation results in accelerated depreciation deductions both for
federal  income tax purposes and for  earnings  and profits  purposes.  Until we
obtain clear  guidance on the proper  interpretation  of the applicable Tax Code
provisions  (perhaps  through  subsequent  clarification  of the law, or perhaps
through our obtaining an IRS private  letter ruling if we choose to pursue one),
(1) we plan to ensure our compliance with the 95% distribution  requirements and
the excise tax  required  distribution  requirement,  both  described in earlier
sections of this summary, by making distributions on the assumption that, in any
given  taxable  year,  we are only  entitled  to the lesser of the two  possible
interpretations' aggregate depreciation deductions, and (2) we intend to perform
all our  tax  reporting  on the  basis  of the  more  conservative  depreciation
methodology  dictated by the first  interpretation  of the  applicable  Tax Code
provisions.

     For properties  that we acquire after we are no longer wholly owned by HRP,
we expect  that for  federal  income tax  purposes  (including  for  purposes of
computing our earnings and profits),  (1) our initial tax basis in such acquired
properties will generally be our acquisition cost for such  properties,  and (2)
we will generally  depreciate our real property on a straight-line basis over 40
years and our  personal  property  over 12  years.  These  results  may vary for
properties we acquire through tax-free or other carryover basis acquisitions.

Taxation of U.S. Shareholders

     Generally.  As used in this summary,  the term "U.S.  Shareholder"  means a
beneficial holder of our common shares that is for federal income tax purposes:

     (1)  a citizen or resident of the United States,

     (2)  a corporation or partnership (or other entity treated as a corporation
          or partnership  for federal income tax purposes)  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),

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

     (4)  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  certain  electing  trusts in
          existence  on August  20,  1996 to the  extent  provided  in  Treasury
          regulations).

As used in this  summary,  the term  "Non-U.S.  Shareholder"  means a beneficial
holder of our common shares that is not a U.S. Shareholder.

     As  long  as  we  qualify  as a  REIT  for  federal  income  tax  purposes,
distributions  made to our  U.S.  Shareholders  out of  current  or  accumulated
earnings  and profits  will be taken into  account by them as ordinary  dividend
income  (but will not be  eligible  for the  dividends  received  deduction  for
corporations).  Distributions that are properly designated by us 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  year,
though  corporate  U.S.  Shareholders  may be required to treat up to 20% of any
capital  gain  dividend  as ordinary  income  pursuant to Section 291 of the Tax
Code. In addition,  we may elect to retain amounts  representing our net capital
gain income.  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  proportionate  share of the net capital gains retained by us as though that
amount were  distributed  and designated a capital gain dividend,  (3) each U.S.
Shareholder  will receive a credit for a proportionate  share of the tax paid by
us, (4) each U.S. Shareholder will increase its adjusted basis in our common

                                       79
<PAGE>

shares by the  excess  of the  amount  of its  proportionate  share of these net
capital gains over its  proportionate  share of the tax paid by us, and (5) both
we and our corporate U.S. Shareholders will make commensurate adjustments in our
respective  earnings and profits for federal  income tax purposes.  If we should
elect to retain our net capital gain in this  fashion,  we will notify each U.S.
Shareholder  of the relevant tax  information  within 60 days after the close of
the affected taxable year.

     For certain  noncorporate  U.S.  Shareholders,  long-term capital gains are
taxed  at  varying  maximum  rates  of 20% or 25%,  depending  upon  the type of
property  disposed of and the previously  claimed  depreciation  with respect to
such  property  at the time of  disposition.  If we  designate  a dividend  as a
capital gain  dividend (or elect to retain a portion of our net capital gain and
have that amount treated as a distributed  and designated  capital gain dividend
in the  manner  described  above),  we will also  designate  the  portion of the
capital  gain  dividend  that  is to  be  taxed  to  certain  noncorporate  U.S.
Shareholders at the varying maximum rates of 20% or 25%.

     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
adjusted basis of the U.S. Shareholder's common shares, but will reduce the U.S.
Shareholder's  basis in our common shares.  To the extent that our distributions
exceed the adjusted basis of a U.S.  Shareholder's  common shares,  they will be
included in income as long-term capital gain (or short-term  capital gain if the
common  shares  have  been  held  for one year or  less),  with  long-term  gain
generally taxed to certain  noncorporate U.S.  Shareholders at a maximum rate of
20%. U.S.  Shareholders may not include in their  respective  income tax returns
any of our net operating losses or any of our capital losses.

     Dividends declared by us in October, November or December of a taxable year
to shareholders of record on a date in those months, will be deemed to have been
received by shareholders on December 31, provided we actually pay such dividends
during the following January.

     The sale or exchange of common shares will result in recognition of gain or
loss to the U.S.  Shareholder in an amount equal to the  difference  between the
amount realized and the U.S.  Shareholder's  adjusted basis in the common shares
sold or  exchanged.  Any gain or loss will be capital gain or loss,  and will be
long-term capital gain or loss if the U.S.  Shareholder's  holding period in the
common shares exceeds one year.  Long-term capital gains will generally be taxed
to certain noncorporate U.S. Shareholders at a maximum rate of 20%. In addition,
any loss upon a sale or exchange of common shares by a U.S.  Shareholder who has
held our  common  shares  for not more  than six  months  (this  holding  period
determined  after applying certain rules under Section 857 of the Tax Code) will
generally  be  treated  as a  long-term  capital  loss  to  the  extent  of  our
distributions  required  to be treated  by such U.S.  Shareholder  as  long-term
capital gain (including, for this purpose, amounts constructively distributed as
long-term  capital  gain by virtue of us electing to retain our net capital gain
in the manner described above).

   
     U.S.  Shareholders  (other than certain  corporations)  who borrow funds to
finance their acquisition of our common shares could be limited in the amount of
deductions allowed for the interest paid on the indebtedness incurred in such an
arrangement.  Under Section 163(d) of the Tax 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 and, if an appropriate  election is made
by such U.S. Shareholder,  capital gain dividend distributions received from us;
however,  distributions treated as a nontaxable return of the U.S. Shareholder's
basis  will not enter  into the  computation  of net  investment  income.  Under
Section 469 of the Tax Code, U.S. Shareholders (other than certain corporations)
generally  will  not  be  entitled  to  deduct  losses  from  so-called  passive
activities  except to the extent of their  income from passive  activities.  For
purposes of these rules, distributions

                                       80
<PAGE>


received  by a U.S.  Shareholder  from us will not be treated  as income  from a
passive  activity and thus will not be available to offset a U.S.  Shareholder's
passive activity losses.
    

     Tax preference and other 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  would require tax preference items to
be allocated to our  shareholders  with respect to any accelerated  depreciation
claimed by us; however, we do not expect to claim accelerated  depreciation with
respect to our properties.

Taxation of Certain Tax-Exempt U.S. 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  certain  of 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,  distributions
made by us to U.S.  Shareholders  that are qualified  pension  plans  (including
individual  retirement accounts) or certain other tax-exempt entities should not
constitute  unrelated business taxable income,  unless the U.S.  Shareholder has
financed the  acquisition of its common shares of our Company with  "acquisition
indebtedness"  within  the  meaning of the Tax Code,  or the  common  shares are
otherwise used in an unrelated trade or business conducted by the U.S.
Shareholder.

     Special  rules  apply  to  certain  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" (defined  below) at any time during a taxable year. A pension trust may be
required  to treat a  certain  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
(less  direct  expenses  related to this  income)  derived  from the  conduct of
unrelated trades or businesses  (determined as if the  pension-held  REIT were a
tax-exempt  pension  fund) to (2) the  pension-held  REIT's  gross  income (less
direct  expenses  related to this  income)  from all  sources,  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 (1) the REIT is  "predominantly  held" (as
defined below) by tax-exempt  pension  trusts,  and (2) 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 holds 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 common shares, and because of the restrictions in
HRP's  declaration of trust regarding the ownership  concentration of beneficial
interests in HRP, we believe that we will not be a pension-held  REIT.  However,
because our common shares will be publicly traded, we cannot completely  control
whether or not we will become a pension-held REIT.

Taxation of Non-U.S. Shareholders

   
     The rules  governing the federal income  taxation of Non-U.S.  Shareholders
(generally,   nonresident  alien  individuals,  foreign  corporations,   foreign
partnerships,  and  foreign  trusts and  estates)  are highly  complex,  and the
following  discussion  is intended  only as a summary of the  applicable  rules.
Non-U.S.  Shareholders  should  consult with their own tax advisors to determine
the impact of  federal,  state,  local,  and  foreign  tax laws,  including  any
reporting requirements, with respect to their investment in our

                                       81
<PAGE>
common shares.  In general,  a Non-U.S.  Shareholder  will be subject to regular
federal income tax in the same manner as a U.S.  Shareholder with respect to its
investment in our common shares if this 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 Tax
Code, which is payable in addition to regular federal  corporate income tax. The
balance  of  this   discussion  on  the  federal  income  taxation  of  Non-U.S.
Shareholders addresses only those Non-U.S.  Shareholders whose investment in our
common  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 by us of a United States real  property  interest
and that is not  designated  by us 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.  Generally,  this dividend will be subject to
federal income withholding tax on the gross amount of the payment at the rate of
30%,  or a 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  to us its
entitlement to benefits under a tax treaty.  A distribution of cash in excess of
our earnings and profits will be treated first as a nontaxable return of capital
that will reduce a Non-U.S.  Shareholder's  basis in its common  shares (but not
below zero) and then as gain from the  disposition of these common  shares,  the
tax  treatment  of which is discussed  below.  A  distribution  in excess of our
earnings  and profits may be subject to 30% (or  applicable  lower  treaty rate)
withholding if at the time of the  distribution it cannot be determined  whether
the  distribution  will be in an amount in excess of our current and accumulated
earnings and profits. If it is subsequently determined that the distribution is,
in fact, in excess of current and accumulated earnings and profits, the Non-U.S.
Shareholder may seek a refund from the IRS. We expect to withhold federal income
withholding tax at the rate of 30% on the gross amount of any  distributions  on
common  shares  made to a Non-U.S.  Shareholder  unless a lower tax treaty  rate
applies and the required IRS form  evidencing  eligibility for that reduced rate
is filed with us.

     For any year in which we  qualify  as a REIT,  our  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 the 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 a special  alternative
minimum tax in the case of nonresident alien  individuals.  These  distributions
may also be subject to a 30% branch  profits  tax under  Section  884 of the Tax
Code in the hands of a corporate  Non-U.S.  Shareholder  that is not entitled to
treaty relief or exemption.  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 distributions,  then subsequent distributions,  up to the amount of
the prior distributions,  will be treated as capital gain dividends.  The amount
of any tax withheld is  creditable  against the Non-U.S.  Shareholder's  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.

   
     Tax  treaties  may  reduce  our  withholding  obligations.   Under  certain
treaties, however, rates below 30% generally applicable to dividends from United
States corporations may not apply to 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   federal   income  tax  liability   with  respect  to  that
distribution,  the Non-U.S.  Shareholder may file with the IRS for a refund.  In
this  regard,  it should be noted 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. Treasury regulations
issued on October 6, 1997 alter the withholding rules on distributions paid to a
Non-U.S.  Shareholder,  and these Treasury  regulations are generally  effective
with respect to distributions paid after December 31, 1999. Under these Treasury
regulations, to obtain a reduced rate of withholding under an income tax treaty,
a Non-U.S. Shareholder generally will be required to provide an Internal Revenue
Service Form W-8 certifying the Non-U.S.  Shareholder's  entitlement to benefits
under the treaty.  The new Treasury  regulations  also provide  special rules to
determine  whether,  for  purposes of  determining  the  applicability  of a tax
treaty, distributions paid to a Non-U.S. Shareholder that is an entity should be
treated as paid to the entity or to those  holding an interest  in that  entity,
and whether the entity or its  holders  are  entitled to benefits  under the tax
treaty.  These Treasury  regulations  also alter the  information  reporting and
backup  withholding  rules applicable to Non-U.S.  Shareholders and, among other
things,  provide  certain  presumptions  under which a Non-U.S.  Shareholder  is
subject  to  backup  withholding  and  information  reporting  until we  receive
certification of its status.
    

     If the common  shares fail to  constitute  a "United  States real  property
interest" within the meaning of Section 897 of the Tax Code, gain on sale of the
common shares by a Non-U.S. Shareholder generally will not be subject to federal
income  taxation  unless  (1)  investment  in the common  shares is  effectively
connected with the Non-U.S.  Shareholder's  United States trade or business,  in
which case, as discussed above, the Non-U.S. Shareholder would be subject to the
same treatment as U.S. Shareholders on the gain, or (2) the Non-U.S. Shareholder
is a nonresident  alien  individual who was present in the United States for 183
days or more  during  the  taxable  year,  in which case the  nonresident  alien
individual will be subject to a 30% tax on the gain.

     The  common  shares  will not  constitute  a United  States  real  property
interest if we are a  "domestically  controlled  REIT,"  defined as  follows.  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 common shares is held
directly  or  indirectly  by  foreign  persons.  We  believe  that  we will be a
domestically  controlled  REIT and that the sale of common  shares by a Non-U.S.
Shareholder will not be subject to federal income taxation. However, because the
our  common  shares are  publicly  traded  (and  because  of  possible  indirect
ownership  through  HRP,  which is also  publicly  traded),  we can  provide  no
assurance  that we  will  be a  domestically  controlled  REIT.  If we are not a
domestically  controlled REIT, whether a Non-U.S.  Shareholder's gain on sale of
common  shares  would be  subject  to  federal  income tax as a sale of a United
States real  property  interest  would depend upon whether the common shares are
"regularly  traded"  (as  defined  by  applicable  Treasury  regulations)  on an
established  securities  market (e.g., the NYSE, on which the common shares will
be listed) and upon the size of the selling Non-U.S.  Shareholder's  interest in
our  Company.  If the gain on the sale of common  shares were subject to federal
income taxation, the Non-U.S. Shareholder would be subject to the same treatment
as a  U.S.  Shareholder  with  respect  to  that  gain,  subject  to  applicable
alternative  minimum  tax and a special  alternative  minimum tax in the case of
nonresident alien individuals. In any event, a purchaser of common shares from a
Non-U.S.  Shareholder  will not be required to withhold on the purchase price if
the purchased  common shares are regularly  traded on an established  securities
market or if we are a domestically controlled REIT. Otherwise,  the purchaser of
common shares may be required to withhold 10% of the purchase  price paid to the
Non- U.S. Shareholder and to remit that amount to the IRS.

     Common  shares  owned or  treated  as owned by an  individual  who is not a
citizen or resident (as defined for United States  federal  estate tax purposes)
of the United States at the time of death will be includable in the individual's
gross estate for United States federal estate tax purposes  unless an applicable
estate tax treaty provides otherwise.

Backup Withholding and Information Reporting Requirements

   
     We will  report  to our  U.S.  Shareholders  and to the IRS the  amount  of
distributions paid during each calendar year and the amount of tax withheld,  if
any. Under the backup  withholding  rules, a U.S.  Shareholder may be subject to
backup  withholding at the rate of 31% with respect to distributions paid unless
the U.S.  Shareholder  (a) is a corporation or comes within certain other exempt
categories and, when required, demonstrates that fact or (b) provides a taxpayer
identification  number,  certifies  as to  no  loss  of  exemption  from  backup
withholding  rules and otherwise  complies with  applicable  requirements of the
backup withholding  rules. A U.S.  Shareholder that does not provide us with its
correct taxpayer  identification  number may be subject to penalties  imposed by
the IRS. In  addition,  we may be required to withhold a portion of capital gain
distributions  to any U.S.  Shareholder  that fails to certify  its  non-foreign
status to us. Any amounts  withheld under the foregoing rules will be creditable
against the U.S.  Shareholder's  federal income tax liability  provided that the
required information is furnished to the IRS.

     We will report to our  Non-U.S.  Shareholders  and to the IRS the amount of
distributions paid during each calendar year and the amount of tax withheld,  if
any.  These  information  reporting  requirements  apply  regardless  of whether
withholding  was reduced or eliminated by an  applicable  tax treaty.  Copies of
these  information  returns may also be made available under the provisions of a
specific  treaty or agreement to the tax authorities in the country in which the
Non-U.S.  Shareholder resides. As discussed above,  withholding tax rates of 30%
and 35% may apply to  distributions  on common shares to Non-U.S.  Shareholders,
and the 1997 Treasury  regulations  will, when effective,  alter the information
reporting and withholding rules applicable to Non-U.S. Shareholders. Among other
things, the 1997 Treasury regulations provide certain presumptions under which a
Non-U.S.  Shareholder  would be subject to backup  withholding  and  information
reporting  until we  receive  certification  from  these  shareholders  of their
Non-U.S.  Shareholder  status.  As  noted,  the 1997  Treasury  regulations  are
generally effective with respect to distributions paid after December 31, 1999.
    

     The payment of the proceeds  from the  disposition  of common  shares to or
through  the  United  States  office of a broker  will  generally  be subject to
information  reporting and backup withholding at a rate of 31% unless the owner,
under  penalties  of  perjury,  certifies  among  other  things  its status as a
Non-U.S.  Shareholder, or otherwise establishes an exemption. The payment of the
proceeds from the disposition of common shares to or through a non-United States
office of a broker  generally  will not be  subject  to backup  withholding  and
information  reporting.  In the case of proceeds  from a  disposition  of common
shares paid to or through a non-United  States  office of a United States broker
or paid to or through a non-United  States office of a non-United  States broker
that is (1) a "controlled  foreign  corporation" for federal income tax purposes
or (2) a person 50% or more of whose gross income from all sources for a certain
three-year  period  was  effectively  connected  with a United  States  trade or
business,  (a) backup  withholding  will not apply  unless the broker has actual
knowledge  that the owner is not a  Non-U.S.  Shareholder,  and (b)  information
reporting  will not apply if the broker has  documentary  evidence  in its files
that the beneficial owner is a Non-U.S. Shareholder unless the broker has actual
knowledge  to the  contrary.  Under  the 1997  Treasury  regulations  (generally
effective  for payments made after  December 31, 1999),  in the case of proceeds
from a disposition of common shares paid to or though a non-United States office
of a United States broker or paid to or through a non-United  States office of a
non-United  States broker that is (1) a  "controlled  foreign  corporation"  for
federal income tax purposes, (2) a person 50% or more of whose gross income from
all sources for a certain  three-year  period was  effectively  connected with a
United  States trade or  business,  (3) a foreign  partnership  with one or more
partners who are United States  persons and who in the aggregate  hold more than
50% of the  income or  capital  interest  in the  partnership,  or (4) a foreign
partnership  engaged in the conduct of a trade or business in the United States,
(a) backup  withholding  will not apply  unless the broker has actual  knowledge
that the owner is not a Non-U.S. Shareholder, and (b) information reporting will
not  apply if the  Non-U.S.  Shareholder  certifies  its  status  as a  Non-U.S.
Shareholder  and  further  certifies  that it has not been,  and at the time the
certificate  is furnished  reasonably  expects not to be,  present in the United
States for a period  aggregating  183 days or more during each  calendar year to
which the certification pertains.

                                       84
<PAGE>

     Any  amounts  withheld  from  a  payment  to a  Non-U.S.  Shareholder  will
generally  be refunded (or credited  against the Non-U.S.  Shareholder's  United
States  federal  income  tax  liability,  if any),  provided  that the  required
information is furnished to the IRS.

Other Tax Considerations

     You should recognize that our and your present federal income tax treatment
may be modified by legislative, judicial, or administrative actions at any time,
which 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 any new tax  legislation  or other  provisions  either  directly  or
indirectly  affecting us or our  shareholders.  Revisions in federal  income tax
laws  and   interpretations  of  these  laws  could  adversely  affect  the  tax
consequences of investment in the common 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.  Our and our shareholders'  state and
local tax  treatment  may not  conform to the  federal  income tax  consequences
discussed above. Consequently, you should consult your own tax advisor regarding
the effect of state and local tax laws on an investment in our common shares.


           ERISA PLANS, KEOGH PLANS AND INDIVIDUAL RETIREMENT ACCOUNTS

General Fiduciary Obligations

     Fiduciaries of a pension,  profit-sharing  or other  employee  benefit plan
("ERISA Plan") subject to Title I of the Employee Retirement Income Security Act
of 1974  ("ERISA") must consider  whether their  investment in our common shares
satisfies the diversification  requirements of ERISA,  whether the investment is
prudent in light of  possible  limitations  on the  marketability  of the common
shares,  whether  they have  authority  to acquire our common  shares  under the
applicable governing instrument and Title I of ERISA, and whether 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 (the "Fiduciary  Penalty").  Fiduciaries of any Individual  Retirement
Account  ("IRA"),  Keogh Plan or other qualified  retirement plan not subject to
Title I of ERISA  ("Non-ERISA  Plan")  should  consider that an IRA or non-ERISA
Plan may only make investments that are authorized by the appropriate  governing
instrument.  Fiduciary  shareholders  should consult their own legal advisers if
they have any concern as to whether the investment is  inconsistent  with any of
the foregoing criteria.

Prohibited Transactions

     Fiduciaries of ERISA Plans and persons  making the investment  decision for
an IRA or other  Non-ERISA  Plan should also  consider  the  application  of the
prohibited  transaction  provisions  of ERISA and the Tax Code in  making  their
investment decision. Sales and certain other transactions between an ERISA Plan,
IRA, or other  Non-ERISA Plan and certain  persons  related to it are prohibited
transactions.  The particular facts  concerning the sponsorship,  operations and
other  investments  of an ERISA Plan,  IRA, or other  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 Tax Code or a penalty under ERISA upon
the  disqualified  person  or party in  interest  with  respect  to the ERISA or
Non-ERISA Plan or IRA. If the disqualified person who engages in the transaction
is the individual on behalf of whom an IRA is maintained  (or his  beneficiary),
the IRA may

                                       85
<PAGE>
lose its tax-exempt status and its assets may be deemed to have been distributed
to such individual in a taxable distribution (and no excise tax will be imposed)
on account of the prohibited transaction.  Fiduciary shareholders should consult
their own legal  advisers if they have any concern as to whether the  investment
is a prohibited transaction.

Special Fiduciary and Prohibited Transactions Considerations

     The  Department  of  Labor  ("DOL"),   which  has  certain   administrative
responsibility  over ERISA Plans as well as over IRAs and other Non-ERISA Plans,
has  issued a  regulation  defining  "plan  assets."  The  regulation  generally
provides that when an ERISA or Non-ERISA Plan or IRA 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 or Non-ERISA  Plan's or IRA'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.

     The regulation  defines a 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 pursuant to 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).  Our common 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.
We expect our common shares to be widely held.

     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,  certain
restrictions ordinarily will not, alone or in combination, affect a finding that
such securities are freely transferable. The restrictions on transfer enumerated
in the regulation as not affecting that finding  include:  any restriction on or
prohibition  against  any  transfer  or  assignment  which  would  result  in  a
termination  or  reclassification  of our  Company  for  federal  or  state  tax
purposes,  or would  otherwise  violate any state or federal law or court order;
any requirement  that advance notice of a transfer or assignment be given to our
Company 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;  any  administrative  procedure  which  establishes an
effective  date, or an event prior to which a transfer or assignment will not be
effective;  and 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 the Declaration of Trust on the transfer of
common  shares do not result in the  failure of our common  shares to be "freely
transferable."  Furthermore,  we believe  that at present  there  exist no other
facts or circumstances  limiting the  transferability of our common 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 the common  shares  will be "widely  held" and that no other
facts and  circumstances  exist  which  restrict  transferability  of the common
shares,  we have  received an opinion of counsel that the common shares will not
fail to be "freely transferable" for purposes of the regulation due to the

                                       86

<PAGE>



restrictions on transfer of the common shares under the Declaration of Trust and
that under the regulation the common shares are publicly offered  securities and
our  assets  will not be deemed to be "plan  assets" of any ERISA  Plan,  IRA or
other Non-ERISA Plan that invests in the common shares.

                                  UNDERWRITING

     Merrill Lynch,  Pierce,  Fenner & Smith  Incorporated  ("Merrill Lynch") is
acting as  representative  (the  "Representative")  of each of the  underwriters
named below (the  "Underwriters")  with  respect to the  offering of  11,000,000
common shares (the "Public  Offering").  Subject to the terms and conditions set
forth in an underwriting  agreement (the  "Underwriting  Agreement"),  among our
Company  and  the  Underwriters,   we  have  agreed  to  sell  to  each  of  the
Underwriters,  and each of the Underwriters severally and not jointly has agreed
to purchase  from us, the number of common  shares set forth  opposite  its name
below.


                                                               Number of
              Underwriter                                    Common Shares

              Incorporated...............................




              Total......................................      11,000,000
                                                               ==========


     In the  Underwriting  Agreement,  the  several  Underwriters  have  agreed,
subject to the terms and conditions  set forth  therein,  to purchase all of the
common shares being sold pursuant to that  agreement if any of the common shares
being sold pursuant to the agreement are purchased. Under certain circumstances,
under the Underwriting Agreement, the commitments of non-defaulting Underwriters
may be increased.

     The Representative  has advised us that the Underwriters  propose initially
to offer the common shares to the public at the initial  public  offering  price
set forth on the cover page of this  prospectus,  and to certain dealers at that
price less a concession  not in excess of $ per common share.  The  Underwriters
may allow,  and dealers may  re-allow,  a discount not in excess of $ per common
share to certain other dealers.  After the initial public  offering,  the public
offering price, concession and discount may be changed.

     We have  granted  an option to the  Underwriters,  exercisable  for 30 days
after the date of this prospectus, to purchase up to 1,650,000 additional common
shares  at the  public  offering  price  set  forth  on the  cover  page of this
prospectus,  less the underwriting  discount. The Underwriters may exercise this
option solely to cover  over-allotments,  if any, made on the sale of the common
shares offered hereby. To the extent that the Underwriters exercise this option,
each Underwriter will be obligated,  subject to certain conditions,  to purchase
approximately  the same  percentage  thereof  which  the  number of shares to be
purchased  by it shown in the  foregoing  table bears to the  11,000,000  shares
offered hereby.

     The following  table shows the per share and total public  offering  price,
underwriting  discount we will pay and the proceeds we will  receive  before our
expenses.  This  information  is presented  assuming  either no exercise or full
exercise of the Underwriters' over-allotment option.

     The expenses of the offering  (exclusive of the underwriting  discount) are
estimated at $2 million and are payable by our Company.

     The common shares are being offered by the several Underwriters, subject to
prior sale, when, as and if issued to and accepted by them,  subject to approval
of certain  legal  matters by counsel for the  Underwriters  and  certain  other
conditions.  The  Underwriters  reserve the right to withdraw,  cancel or modify
their offer and to reject orders in whole or in part.

     We have agreed for a period of 90 days,  and the Managing  Trustees and HRP
have agreed for a period of one year, after the date of this prospectus, subject
to certain exceptions,  not to directly or indirectly (1) offer,  pledge,  sell,
contract to sell,  sell any option or contract to purchase,  purchase any option
or  contract  to sell,  grant any  option,  right or warrant  for the sale of or
otherwise  dispose of or transfer any common  shares or  securities  convertible
into or exchangeable or exercisable for or repayable with common shares, whether
now owned or thereafter  acquired by the person  executing the agreement or with
respect to which the person  executing  the  agreement  thereafter  acquires the
power of disposition,  or file a registration statement under the Securities Act
of 1933  with  respect  to the  foregoing  or (2)  enter  into any swap or other
agreement  that  transfers,  in whole or in part,  the economic  consequence  of
ownership of the common shares  whether any swap or transaction is to be settled
by delivery of common shares or other securities, in cash or otherwise,  without
the prior written consent of Merrill Lynch on behalf of the Underwriters.

   
     We expect that the common  shares will be approved  for listing on the NYSE
after pricing of the offering,  subject to notice of issuance,  under the symbol
"__." In order to meet the  requirements  for listing  the common  shares on the
NYSE, the Underwriters have undertaken to sell lots of 100 or more common shares
to a minimum of 2,000 beneficial holders.
    

     The  Underwriters  do not  intend to  confirm  sales of the  common  shares
offered hereby to any accounts over which they exercise discretionary authority.

     We and HRP have  agreed  to  indemnify  the  Underwriters  against  certain
liabilities,  including  liabilities  under  the  Securities  Act of  1933 or to
contribute  to  payments  the  Underwriters  may be  required to make in respect
thereof.

     Until the distribution of the common shares is completed,  rules of the SEC
may limit the ability of the  Underwriters  and certain selling group members to
bid for and purchase  the common  shares.  As an  exception to these rules,  the
Representative is permitted to engage in certain transactions that stabilize the
price  of the  common  shares.  Stabilization  transactions  consist  of bids or
purchases  for the purpose of pegging,  fixing or  maintaining  the price of the
common shares.

     If the  Underwriters  create  a short  position  in the  common  shares  in
connection with the offering, i.e., if they sell more common shares than are set
forth on the cover page of this prospectus,  the  Representative may reduce that
short   position  by  purchasing   common   shares  in  the  open  market.   The
Representative  may also elect to reduce any short position by exercising all or
part of the over-allotment option described above.

     The  Representative  may also impose a penalty bid on certain  Underwriters
and  selling  group  members.  This means that if the  Representative  purchases
common shares in the open market to reduce the  Underwriters'  short position or
to stabilize the price of the common shares,  they may reclaim the amount of the
selling  concession  from the  Underwriters  and selling  group members who sold
those shares as part of the offering.

     In general,  purchases of a security for the purpose of stabilization or to
reduce a short  position could cause the price of the security to be higher than
it might be in the absence of those  purchases.  The imposition of a penalty bid
might also have an effect on the price of the common  shares to the extent  that
it discourages resales of the common shares.

     Neither  we  nor  any of  the  Underwriters  makes  any  representation  or
prediction as to the direction or magnitude of any effect that the  transactions
described above may have on the price of the common shares. In addition, neither
we nor any of the Underwriters makes any representation  that the Representative
will  engage  in these  types  transactions  or that  these  transactions,  once
commenced, will not be discontinued without notice.

     Prior to this  offering,  there has been no public  market  for our  common
shares.  The initial public offering price was determined  through  negotiations
among us, HRP and the  Representative.  Among the  factors  considered  in these
negotiations,  in addition to prevailing market conditions, were dividend yields
and  financial  characteristics  of publicly  traded  REITs that we, HRP and the
Representative  believe to be comparable to our Company, the expected results of
our  operations,  estimates  of  our  future  business  potential  and  earnings
prospects and the current state of the real estate  markets and the economy as a
whole.

     We will pay Merrill Lynch an advisory fee equal to % of the gross  proceeds
received from the sale of common shares to public  investors in the offering for
financial advisory services rendered in connection with our formation.

     We are currently  negotiating a new $100 million revolving loan arrangement
to be used for working capital and new acquisitions  after the completion of the
Public Offering. This credit facility may be arranged by an affiliate of Merrill
Lynch.  An  origination  fee of $ will be paid to Merrill Lynch if Merrill Lynch
arranges the credit facility.

     In the ordinary course of their respective businesses, the Underwriters and
their  affiliates  have engaged in, and may in the future engage in,  commercial
banking and investment banking transactions with us.

     In addition to the Public  Offering,  the Company will offer 350,000 common
shares  directly  to Barry M.  Portnoy  and  Gerard M.  Martin,  which  they may
purchase  directly or indirectly  through an entity to be  established.  Messrs.
Portnoy and Martin will pay the same price paid by public investors, and we will
pay no  underwriting  discount  with  respect to the sale of these  shares.  The
Underwriters  will not  have an  over-allotment  option  with  respect  to these
shares.

                         Senior Housing Properties Trust

            Introduction to Unaudited Pro Forma Financial Statements

         The  following  unaudited pro forma balance sheet at September 30, 1998
is  intended  to  present  the  financial  position  of  the  Company  as if the
transactions  described in the notes had been  consummated  as of September  30,
1998.  The following  unaudited  pro forma  statements of income are intended to
present the results of  operations of the Company as if these  transactions  had
been consummated as of the beginning of the periods presented.

         These  unaudited pro forma  financial  statements  are not  necessarily
indicative  of the expected  financial  position or results of operations of the
Company for any future  period.  Differences  could  result  from many  factors,
including  future  changes in the  Company's  investments,  changes in  interest
rates,  changes  in the  capital  structure  of the  Company  and  delays in the
acquisition of certain  properties.  The pro forma information should be read in
conjunction  with all of the  financial  statements  and notes  thereto and with
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations" included elsewhere in this prospectus.

                         Statement of Income Adjustments

E.   Represents historical rental and other income,  interest,  depreciation and
     general and  administrative  expenses arising from the ownership of the HRP
     Properties.  Rental  and  mortgage  interest  income is based on leases and
     mortgages  in effect with HRP.  Interest  expense  represents  an allocated
     portion of HRP's interest  costs.  Depreciation  is computed based on HRP's
     historical cost on a 40 year life for buildings and  improvements  and a 12
     year life for personal property.  General and  administrative  expenses are
     based on the advisory agreements in effect with REIT Management & Research,
     Inc.  ("RMR")  and its  predecessor  plus an  allocated  portion  of  HRP's
     historical costs.

F.   Represents  rental  income,  depreciation  and general  and  administrative
     expenses  arising from the  acquisition  of five of the HRP  Properties  in
     September  1998,  the  acquisition of one of the HRP Properties in May 1997
     and the  acquisition  of four of the HRP Properties in September 1997 as if
     the  properties  had  been  acquired  as of the  first  day of the  periods
     presented.   Rental   income  is  based  on  leases  in  effect  with  HRP.
     Depreciation  is computed based on HRP's  historical cost on a 40 year life
     for buildings and  improvements  and a 12 year life for personal  property.
     General and  administrative  expenses are based on the advisory  agreements
     with RMR and its predecessor.

G.   Represents the incremental  interest and  amortization  expense of up front
     costs from the Proposed Secured Debt.

H.   Represents  rental  income,  depreciation  and general  and  administrative
     expenses arising from the Proposed Property  Acquisition.  Rental income is
     based on the agreement in effect but does not include  income on properties
     under  construction  prior  to the time  that  they  commenced  operations.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Trustees and Shareholder of Senior Housing Properties Trust:

We have  audited the  accompanying  combined  balance  sheets of Certain  Senior
Housing  Properties  (wholly owned by HRPT Properties  Trust) as of December 31,
1997 and 1996, and the related combined statements of income, ownership interest
of HRPT  Properties  Trust and cash  flows,  for each of the three  years in the
period  ended   December  31,  1997.   These   financial   statements   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  generally   accepted  auditing
standards.  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 combined  financial  statements  referred to above  present
fairly, in all material  respects,  the combined  financial  position of Certain
Senior Housing  Properties  (wholly owned by HRPT Properties  Trust) at December
31, 1997 and 1996, and the combined  results of their  operations and their cash
flows for each of the three years in the period  ended  December  31,  1997,  in
conformity with generally accepted accounting principles.

                        CERTAIN SENIOR HOUSING PROPERTIES
                     (wholly owned by HRPT Properties Trust)
                     NOTES TO COMBINED FINANCIAL STATEMENTS


Note 1.  Organization

The combined  financial  statements of Certain  Senior Housing  Properties  (the
"Properties")  include the accounts of 70 (75 at September 30, 1998)  healthcare
properties  and 9 mortgage  investments  secured by  healthcare  properties  and
certain related assets and liabilities located in 36 states as if the Properties
were owned in an entity  separate from HRPT Properties  Trust ("HRP").  However,
the Properties do not constitute a legal entity.

Senior  Housing  Properties  Trust  (the  "Company"),  a  Maryland  real  estate
investment  trust,  was organized on December 16, 1998.  The Company is a wholly
owned  subsidiary  of HRP.  The Company is in the  process of an initial  public
offering  pursuant  to which it will sell 11  million  shares to the  public and
350,000 shares to affiliates (combined, the "Offering").  The Company intends to
file a Form  S-11  registration  statement  with  the  Securities  and  Exchange
Commission in connection with the Offering.

Prior to the  consummation  of the Offering,  the Company will acquire  (through
contribution from HRP) 100% ownership of the Properties.

Note 2.  Summary of Significant Accounting Policies

Basis  of  Presentation.  All of the  Properties  are  owned  by HRP  and  HRP's
historical basis in the Properties has been presented.  Substantially all of the
rental income and mortgage  interest income received by HRP from the tenants and
mortgagors of the Properties is deposited in and  commingled  with HRP's general
corporate funds.  Certain capital investments and other cash requirements of the
Properties  were  paid by HRP  and  were  charged  directly  to the  Properties.
Interest  expense is allocated based on HRP's  historical  interest expense as a
percentage  of  average   historical  real  estate   investments.   General  and
administrative  costs of HRP were  allocated  to the  Properties  based on HRP's
investment  advisory agreement formula and certain costs were allocated based on
historical  costs  as a  percentage  of HRP's  average  historical  real  estate
investments.  In the opinion of management,  the methods for allocating interest
and general and administrative expenses are reasonable. It is not practicable to
estimate  additional  costs that would have been  incurred from the existence of
the Properties in a separate entity.

Real Estate Properties and Mortgages.  Depreciation on real estate properties is
expensed on a  straight-line  basis over estimated  useful lives of 40 years for
buildings and improvements and 12 years for personal property. Impairment losses
on properties are recognized  where indicators of impairment are present and the
undiscounted  cash flow (net realizable  value) estimated to be generated by the
properties  are  less  than  the  carrying  amount  of  such   properties.   The
determination  of net realizable  value includes  consideration  of many factors
including  income to be earned from the property,  holding  costs  (exclusive of
interest),   estimated  selling  prices,  and  prevailing  economic  and  market
conditions.  Based upon these factors,  the  accompanying  financial  statements
include no impairment losses.

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.  Additional
rent and interest revenue is recognized as earned.

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

New Accounting  Pronouncements.  The Financial  Accounting  Standards  Board has
issued  Financial  Accounting  Standards Board Statement No. 128,  "Earnings Per
Share" ("FAS 128"),  Statement No. 129, "Disclosure of Information about Capital
Structure"  ("FAS 129"),  Statement No. 130,  "Reporting  Comprehensive  Income"
("FAS 130"), Statement No. 131, "Disclosures About Segments of an Enterprise and
Related  Information"  ("FAS  131")  and  Statement  No.  133,  "Accounting  for
Derivative  Instruments and Hedging Activities" ("FAS 133"). FAS 128 and FAS 129
were adopted for the 1997  financial  statements.  The adoption of each of these
statements had no impact on these financial statements. FAS 130 and FAS 131 must
be adopted for the 1998 financial statements and FAS 133 must be adopted for the
year 2000 financial statements. Management anticipates that FAS 130, FAS 131 and
FAS 133 will have no impact on the financial  condition or results of operations
of the Properties.

Income  Taxes.   Throughout  the  periods  presented  herein,   the  Properties'
operations  were  included  in HRP's  income tax  returns.  HRP is a real estate
investment   trust  under  the  Internal  Revenue  Code  of  1986,  as  amended.
Accordingly,  it is not subject to Federal  income taxes provided it distributes
its taxable income and meets certain other requirements for qualifying as a real
estate investment trust. However, it is subject to certain state and local taxes
on its income and property.

Note 3.  Real Estate Properties

These  financial  statements  include 70  properties  representing  an aggregate
investment of $604.0  million.  In September 1998, five nursing homes were added
to the Properties for an aggregate investment of $11.4 million.

The owned  properties  are  leased  on a triple  net lease  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-collateralized,  cross-defaulted, cross-guaranteed and provide for renewal
terms at existing  rates  followed by several  market rate  renewal  terms.  The
triple  net  leases  generally  require  the  lessee  to  provide  all  property
management services.

The future minimum lease payments to be received during the current terms of the
leases as of December 31, 1997, are  approximately  $62.7 million in 1998, $63.1
million in 1999,  $63.8 million in 2000, $63.8 million in 2001, $66.2 million in
2002 and $726.1 million thereafter.

                                                  =======================
                                                           
At December 31, 1997, the interest rates on the mortgage investments ranged from
9% to 13.75% per annum.

Note 5.  Commitments and Contingencies

At December 31, 1997,  the  Properties had total  commitments  aggregating  $6.2
million  to  fund  or  finance  improvements  to  certain  leased  or  mortgaged
properties.  In December  1998,  HRP agreed to purchase  and lease 14 new senior
housing properties for an aggregate amount of $193.8 million  (unaudited).  Upon
completion  of the  Offering  the Company  will assume  these  commitments.  The
acquisition  of these  properties  is  subject  to  various  closing  conditions
customary in real estate  transactions and no assurances can be given as to when
or if this transaction will be consummated.

Note 6.  Transactions with Affiliates

HRP has  entered  an  investment  advisory  agreement  with  REIT  Management  &
Research, Inc. ("RMR"), an affiliate of HRP. RMR provides investment, management
and  administrative  services to HRP, and will provide  similar  services to the
Company.  Prior to  December  31,  1997,  such  services  were  provided by HRPT
Advisors, Inc. ("Advisors") on similar terms. RMR and Advisors are each owned by
Gerard M. Martin and Barry M.  Portnoy,  who also serve as managing  trustees of
HRP and will serve as Managing  Trustees of the  Company.  RMR and  Advisors are
paid  by HRP  based  on a  formula  amount  of  gross  invested  assets  of HRP.
Investment advisory fees paid by HRP during 1995, 1996, and 1997 with respect to
the  Properties  would have been $2.9  million,  $3.2 million and $3.5  million,
respectively. RMR is also entitled to an incentive fee paid in restricted shares
of common stock based on a formula.  Concurrent  with the Offering,  the Company
will enter a separate agreement with RMR on substantially similar terms.

The  financial   statements  presented  include  mortgage   investments,   rents
receivable, other liabilities and security deposits. Except as follows, the fair
values  of  the  financial  instruments  and  commitments  were  not  materially
different from their carrying values at December 31, 1997:

Commitments                          --                    6,207

The fair  values  of the real  estate  mortgages  are based on  estimates  using
discounted cash flow analysis and currently  prevailing rates. The fair value of
the commitments represents the actual amounts committed.

Note 8.  Concentration of Credit Risk

The assets  included in these  financial  statements  are primarily  invested in
income producing real estate located  throughout the United States.  At December
31, 1996 and 1997, the  investment in properties  purchased from and operated by
Marriott International,  Inc. ("Marriott") was $325.5 million,  representing 56%
and  53%,  respectively,  of  total  investments  included  in  these  financial
statements. During 1996 and 1997, the revenue from properties leased to Marriott
was $30.5 million and $30.4  million,  respectively,  representing  58% and 47%,
respectively, of total investments included in these financial statements.

                         Senior Housing Properties Trust
                             Notes to Balance Sheet
                                December 21, 1998

Note 1.  Organization

Senior Housing  Properties  Trust, a Maryland real estate  investment trust (the
"Company"),  was  organized on December 16, 1998.  The Company is a wholly owned
subsidiary of HRPT Properties Trust ("HRP"). The Company is in the process of an
initial public  offering  pursuant to which it plans to issue  approximately  11
million shares to the public and 350,000 shares to affiliates (collectively, the
"Offering"). The Company intends to file a Form S-11 registration statement with
the Securities and Exchange Commission in connection with the proposed Offering.

The Company has had no operations.  Prior to the  consummation  of the Offering,
the Company will enter into certain transactions (the "Formation  Transactions")
that are  expected  to result in the  Company  becoming a publicly  traded  real
estate investment trust organized to acquire and own senior housing,  congregate
communities,  assisted  living  properties  and nursing homes that are leased to
unaffiliated tenants.

Note 2.  Federal Income Taxes

The  Company  intends to qualify as a real  estate  investment  trust  under the
Internal Revenue Code of 1986, as amended.  Accordingly, the Company expects not
to be subject to federal income taxes provided it distributes its taxable income
and meets certain other  requirements for qualifying as a real estate investment
trust.  The  Company  will be subject to  certain  state and local  taxes on its
income and property.

Note 3.  The Formation Transactions

Prior  to  the  consummation  of the  Offering,  the  Company  will  acquire  84
healthcare  properties and certain related assets and  liabilities  from HRP. In
addition,  prior to the  consummation  of the Offering,  the Company will assume
from HRP an agreement to purchase and lease 14 new  healthcare  properties.  The
acquisition  of these 14  healthcare  properties  is  expected to occur upon the
closing of the Offering.

Concurrently with the closing of the Offering, the Company will distribute, as a
dividend,  13.2  million of its shares to HRP  shareholders  on the basis of one
share of the Company for 10 shares of HRP. HRP will retain 13.2  million  shares
as an equity investment in the Company.  At the conclusion of the Offering,  36%
of the Company will be owned by HRP and  affiliates and 64% will be owned by the
general public.

Immediately  following  the  offering,  the  Company  will  mortgage  finance 14
properties for $250 million.  Proceeds will be used to repay debt to HRP created
by the formation of the Company.

Item 32.   Sales to Special Parties.

         See Item 33.

Item 33.   Recent Sales of Unregistered Securities.

         On December 16, 1998, Senior Housing Properties Trust (the "Trust") was
initially  capitalized  through  the  issuance  of  26,374,760  shares  to  HRPT
Properties Trust ("HRP") in exchange for $263,747.60.  HRP is currently the sole
shareholder  of the Trust.  The 26,374,760  shares  currently  outstanding  were
purchased for investment and for the purpose of organizing the Trust.  The Trust
believes  that  the  issuance  and  sale  of such  securities  are  exempt  from
registration pursuant to Section 4(2) of the Securities Act of 1933, as amended.

Item 34.   Indemnification of Directors and Officers.

         The Maryland REIT law permits a Maryland real estate  investment  trust
to include in its Declaration of Trust a provision limiting the liability of its
trustees and officers to the trust and its shareholders for money damages except
for liability resulting from (a) actual receipt of an improper benefit or profit
in  money,  property  or  services  or  (b)  active  and  deliberate  dishonesty
established by a final  judgment as being  material to the cause of action.  The
Declaration  of Trust of the Trust  contains such a provision  which  eliminates
such liability to the maximum extent permitted by the Maryland REIT law.

         The  Declaration  of Trust of the Trust  authorizes  it, to the maximum
extent  permitted by Maryland law, to obligate itself to indemnify and to pay or
reimburse reasonable expenses in advance of final disposition of a proceeding to
(a) any present or former trustee or officer or (b) any individual  who, while a
trustee  of the Trust and at the  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 trustee,  director,
officer  or  partner  of  such  real  estate  investment   trust,   corporation,
partnership,  joint venture,  trust,  employee  benefit plan or 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
Trustee or officer of the Trust.  The By-laws of the Trust  obligate  it, to the
maximum  extent  permitted by Maryland law, to indemnify and to pay or reimburse
reasonable  expenses in advance of final  disposition of a proceeding to (a) any
present or former  trustee or officer who is made a party to the  proceeding  by
reason of his  service  in that  capacity  or (b) any  individual  who,  while a
Trustee or officer of the Trust and at the  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 trustee,
director,  officer or partner of such real estate investment trust, corporation,
partnership, joint venture, trust,

                                      II-1
<PAGE>
employee  benefit  plan or  other  enterprise  and  who is  made a party  to the
proceeding  by reason of his  service  in that  capacity,  against  any claim or
liability  to  which  he may  become  subject  by  reason  of such  status.  The
Declaration  of Trust and By-laws also permit the Trust to indemnify and advance
expenses  to any  person  who  served a  predecessor  of the Trust in any of the
capacities  described  above  and to any  employee  or agent  of the  Trust or a
predecessor of the Trust. The Bylaws require the Trust to indemnify a trustee or
officer who has been successful,  on the merits or otherwise,  in the defense of
any  proceeding  to which he is made a party by  reason of his  service  in that
capacity.

         The Maryland REIT law permits a Maryland real estate  investment  trust
to indemnify  and advance  expenses to its  trustees,  officers,  employees  and
agents to the same extent as permitted by the Maryland  General  Corporation Law
(the  "MGCL") for  directors  and  officers of Maryland  corporations.  The MGCL
permits a  corporation  to  indemnify  its  present  and  former  directors  and
officers,  among others, against judgments,  penalties,  fines,  settlements and
reasonable  expenses actually incurred by them in connection with any proceeding
to which  they may be made a party by reason of their  service in those or other
capacities unless it is established that (a) the act or omission of the director
or officer was material to the matter giving rise to the  proceeding and (i) was
committed  in bad  faith  or (ii)  was  the  result  of  active  and  deliberate
dishonesty,  (b) the director or officer actually  received an improper personal
benefit  in  money,  property  or  services  or (c) in the case of any  criminal
proceeding, the director or officer had reasonable cause to believe that the act
or omission was unlawful.  However,  under the MGCL, a Maryland  corporation may
not indemnify a director for an adverse judgment in a suit by or in the right of
the  corporation  or for a judgment  of  liability  on the basis  that  personal
benefit  was  improperly  received,   unless  in  either  case  a  court  orders
indemnification  and then only for  expenses.  In  addition,  the MGCL permits a
corporation  to advance  reasonable  expenses to a director or officer  upon the
corporation's receipt of (a) a written affirmation by the director or officer of
his good faith  belief  that he has met the  standard of conduct  necessary  for
indemnification  by the corporation  and (b) a written  undertaking by or on his
behalf to repay the amount paid or  reimbursed  by the  corporation  if it shall
ultimately be determined that the standard of conduct was not met.

         The form of Underwriting  Agreement to be filed by amendment as Exhibit
1.1  to  this   Registration   Statement   will   provide  for  the   reciprocal
indemnification by the Underwriters of the Trust, and its trustees, officers and
controlling  persons and by the Trust of the Underwriters,  and their respective
directors,  officers and controlling persons,  against certain liabilities under
the Securities Act.

Item 35.    Treatment of Proceeds From Stock Being Registered.

     The  consideration  to be  received  by the  Trust  for the  common  shares
registered will be credited to the appropriate capital stock account.

         December 24, 1998)

99.2     Consent of Arthur G.  Koumantzelis to being named as a Trustee nominee.
         (Previously filed as an exhibit to the registration  statement filed on

Item 37.   Undertakings.

     The Trust hereby  undertakes to provide to the  Underwriters at the closing
specified in the Underwriting Agreement,  certificates in such denominations and
registered  in such  names as  required  by the  Underwriters  to permit  prompt
delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933,  as amended,  may be permitted to  trustees,  officers and  controlling
persons of the Trust  pursuant to the foregoing  provisions,  or otherwise,  the
Trust has been  advised  that in the  opinion  of the  Securities  and  Exchange
Commission  such  indemnification  is against  public policy as expressed in the
Securities Act of 1933, as amended,  and is,  therefore,  unenforceable.  In the
event that a claim for indemnification  against such liabilities (other than the
payment  by the Trust of  expenses  incurred  or paid by a  trustee,  officer or
controlling  persons of the Trust in the successful defense of any action,  suit
or  proceeding) is asserted by such trustee,  officer or  controlling  person in
connection with the securities being  registered,  the Trust will, unless in the
opinion of its counsel  the matter has been  settled by  controlling  precedent,
submit to a court of  appropriate  jurisdiction  the  question  of whether  such
indemnification  is against  public policy as expressed in the Securities Act of
1933, as amended, and will be governed by the final adjudication of such issue.

     The undersigned registrant hereby undertakes that:

     (1) For purposes of determining  any liability  under the Securities Act of
1933, as amended,  the information  omitted from the form of prospectus filed as
part of this registration  statement in reliance upon Rule 430A and contained in
a form of prospectus  filed by the registrant  pursuant to Rule 424(b)(1) or (4)
or 497(h) under the  Securities  Act of 1933, as amended,  shall be deemed to be
part of this registration statement as of the time it was declared effective.

     (2) For the purpose of determining  any liability  under the Securities Act
of 1933,  as amended,  each  post-effective  amendment  that  contains a form of
prospectus  shall be deemed to be a new registration  statement  relating to the
securities  offered  therein,  and the offering of such  securities at that time
shall be deemed to be the initial bona fide offering thereof.
