         The  Company's  principal  executive  offices are located at 400 Centre
Street, Newton, Massachusetts 02158, and its telephone number is (617) 332-3990.

         Investment  Policy and Method of Operation.  The  Company's  investment
goals are  current  income for  distribution  to  shareholders,  capital  growth
resulting  from  appreciation  in the residual  value of owned  Properties,  and
preservation  and protection of shareholders'  capital.  The Company's income is
derived  primarily  from  rent  and  interest  payments  under  its  leases  and
mortgages.

         The Company's day to day  operations  are conducted by REIT  Management
and Research,  Inc.  ("RMR"),  the Company's  investment  manager.  RMR provides
investment,  management,  property management and administrative services to the
Company.  RMR originates and presents investment  opportunities to the Company's
Board of Trustees (the "Trustees").  In evaluating  potential  investments,  the
Company  considers such factors as: the historical and projected  rents received
and  likely to be  received  from the  property  to meet  operational  needs and
financing  obligations and to provide a competitive  market return on investment
to the Company;  the historic and expected  operating  expenses,  including real
estate  taxes,  incurred  and  expected to be incurred  at the  properties;  the
growth,  tax and regulatory  environments of the market in which the property is
located;  the  quality,  experience,  and credit  worthiness  of the  property's
operator and tenants; an appraisal of the property, if available;  occupancy and
demand for similar  properties in the same or nearby markets;  the  construction
quality,  physical condition and design of the property; the geographic area and
type of  property;  and the pricing of  comparable  properties  as  evidenced by
recent arms length market sales.

         Prior to investing in properties, the Company obtains title commitments
or policies of title  insurance  insuring that the Company holds title to or has
mortgage interests in such properties, free of material liens and encumbrances.

         The  Company's  investments  are  structured  using leases with minimum
and/or additional rent and escalation  provisions,  loans with fixed or floating
rates, joint ventures and partnerships with affiliated or unaffiliated  parties,
commitments  or options to purchase  interests  in real  estate,  mergers or any
combination of the foregoing that will best suit the particular investment.

         In  connection  with its current  bank  credit  facility  (the  "Credit
Facility"),  the Company has agreed to obtain lender approval  before  exceeding
investment  concentrations based on certain criteria (see - "Borrowing Policy").
Among  these are that no more than 40% of its  investments  be  operated  by any
single tenant or mortgagor,  that investments in a) rehabilitation treatment, b)
acute  care,  c) medical  office and clinic  buildings,  and d)  investments  in
government office properties not exceed 40%, 15%, 55% and 40%, respectively,  of
total investments and that no new psychiatric care or hotel investments be made.
The  Company is  currently  in  discussions  with its  lenders  to modify  these
restrictions.  In addition to these  restrictions,  the Trustees  may  establish
limitations as they deem  appropriate  from time to time. No limits,  other than
those in  connection  with the Credit  Facility,  have been set on the number of
properties in which the Company will seek to invest,  or on the concentration of
investments  involving  any one  facility or  geographical  area;  however,  the
Trustees  consider  concentration of investments in determining  whether to make
new or increase existing investments.

         The Company's  Declaration of Trust (the  "Declaration")  and operating
policies  provide that any  investment in  facilities  owned or operated by RMR,
persons  expressly  permitted under the Declaration to own more than 8.5% of the
Company's  shares,  or any company  affiliated with any of the foregoing must be
approved by a majority of the Trustees not affiliated  with any of the foregoing
(the "Independent Trustees").

         The Company has in the past and may in the future  consider,  from time
to time, the acquisition of or merger with other  companies  engaged in the same
business as the  Company;  however,  the Company  has no present  agreements  or
understandings  concerning any such  acquisition  or merger.  The Company has no
present  intention of investing in the  securities  of others for the purpose of
exercising control.

         Borrowing  Policy.  In  addition  to the  use of  equity,  the  Company
utilizes short-term and long-term borrowings to finance investments. The Company
has a Credit  Facility for an aggregate  amount of $450 million.  The Company is
currently in discussion  with the lenders under the Credit Facility to amend the
Credit Facility,  to modify certain covenants of the Company and to increase the
maximum principal amount that may be outstanding.  No assurances can be given at
this time that the Company and such lenders  will reach a final  agreement as to
such  changes.  The  Credit  Facility  (which is  guaranteed  by  certain of the
Company's  subsidiaries)  is used for  acquisition  

                                       2
<PAGE>

funding on an interim  basis until  equity or long term debt is raised,  working
capital and general business purposes.  Outstanding  borrowings under the Credit
Facility at December 31, 1997 were $200 million.

         The  Company's  borrowing  guidelines  established  by its Trustees and
covenants in various debt  agreements  prohibit the Company from  maintaining  a
debt to equity ratio of greater than 1 to 1. At December 31, 1997, the Company's
debt to equity ratio was .62 to 1. The  Declaration  prohibits  the Company from
incurring secured and unsecured indebtedness which in the aggregate exceeds 300%
of  the  net  assets  of the  Company,  unless  approved  by a  majority  of the
Independent  Trustees.  There can be no assurance  that debt capital will in the
future be available at  reasonable  rates to fund the  Company's  operations  or
growth.

         In February 1997,  the Company  entered into an agreement to acquire 30
office  buildings  containing  3.4 million square feet (the  "Government  Office
Properties"),  substantially  all of which are leased to various agencies of the
United  States  Government.  As of December  31, 1997,  the Company  acquired 29
properties,  one of which is under construction,  and elected not to acquire one
property.  Subsequent to December 31, 1997,  one of the 29 properties  was sold.
The Company's aggregate purchase price for the 29 properties (3.3 million square
feet)  was  approximately  $439  million.  The  total  purchase  price  for  the
Government  Office Properties was paid by the issuance of $77 million in shares,
the  assumption  of  approximately  $27 million of debt by  subsidiaries  of the
Company  secured  by  mortgages  on three  acquired  properties,  and a net cash
payment of  approximately  $335 million,  which was used in part to retire other
debt of the seller assumed by the Company as part of the acquisition transaction
and to pay closing costs.

         During  1997,  the Company  purchased  42 medical and other  office and
clinic buildings for an aggregate  purchase price of approximately $525 million.
Acquisitions  of facilities or buildings  with a purchase  price of at least $25
million  included the  following:  (a) a first class office  building in midtown
Manhattan containing approximately 420,368 square feet purchased in October 1997
for  approximately  $110 million (this building is 100% occupied under long term
leases to three  tenants,  with the  majority of the  building  being  leased to
Health  Insurance  Plan of  Greater  New  York,  a large  not-for-profit  health
maintenance   organization);   (b)  two   first   class   buildings   containing
approximately  330,715 square feet plus two parking structures for approximately
1,700 cars located in West Los Angeles  purchased in May 1997 for  approximately
$109 million  (these  buildings are known as the Cedars Sinai Medical Towers and
Garages  and are  located  adjacent  to the  Cedars  Sinai  Medical  Center,  an
investment grade rated not-for-profit  hospital which is also the largest tenant
in these  buildings);  (c) an office complex in Austin,  Texas  containing  five
commercial office properties,  with approximately  441,145 square feet purchased
in  December  1997 for $79  million;  (d) a first  class 25 story  office  tower
located in Philadelphia  containing  approximately 608,161 square feet purchased
in  November  1997 for  approximately  $79  million  (approximately  98% of this
building is leased on a long-term basis to SmithKline  Beecham  Corporation,  an
investment   grade   rated   international   pharmaceutical   manufacturer   and
distributor);  and  (e)  20  medical  office  and  clinic  buildings  containing
approximately 373,500 square feet located in central Massachusetts  purchased in
May 1997 for approximately $47 million (these buildings are triple net leased on
a long  term  basis  to a  regional  health  maintenance  organization  that  is
partially owned by Tenet  Healthcare  Corporation).  Certain of these properties
are gross leased and the net  operating  income which the Company  realizes from
these investments will depend upon the efficiency with which the Company is able
to operate these buildings.

         In  May  1997,  the  Company  purchased  for  $14  million  a  200-unit
retirement  housing property located in Spokane,  Washington.  This property and
three  other  retirement  housing  properties  (629 units)  purchased  for $87.5
million in December  1996 are all net leased to  Brookdale  Living  Communities,
Inc.  ("BLCI") for an initial term of 23 years plus renewal options  totaling an
additional 50 years. During 1997, BLCI was recapitalized by two public offerings
of equity and as of December  31, 1997 had an equity  market  capitalization  of
over $124 million.

         During the period  January 1, 1998 through  March 5, 1998,  the Company
acquired  11  medical  and  other  office  buildings  for  $91.7  million.  This
acquisition was funded in part with  borrowings  under the Company's bank credit
facility.  

         During the period  January 1, 1997 through  March 5, 1998,  the Company
received $69.6 million of regularly scheduled principal payments and prepayments
of mortgage loans.

Financing

         In October  1996,  the  Company  sold  three  tranches  of  convertible
subordinated  debentures  totaling $240  million.  All of these  debentures  are
convertible  into common  shares at a rate of $18 per share and are  callable at
par by the Company at any time on or after  October 1, 1999.  During  1997,  the
trading price of the Company's shares has averaged above $18 per share.  Through
March 5,  1998,  approximately  $29.2  million  of these  debentures  have  been
converted into approximately 1.6 million common shares.

         In March 1997, the Company issued  27,025,000 common shares in a public
offering.  The gross proceeds of the offering were $510.1  million  ($18.875 per
share),  and the net  proceeds to the  Company  were  $483.2  million.  Such net
proceeds were used to acquire the Government Office Properties.  During February
1998,  the Company  issued an  aggregate of  5,495,776  common  shares in public
offerings and received net proceeds of $104.4 million,  which were used to repay
amounts  outstanding  under the Company's Credit Facility,  for acquisitions and
general business purposes.

         In July 1997, the Company issued $200 million of Remarketed Reset Notes
due  July  9,  2007  ("Reset   Notes").   The  net  proceeds  of  that  issuance
(approximately  $199  million)  were used to prepay  other  indebtedness  of the
Company then due in 1999 ($125 million) and to reduce amounts  outstanding under
the  Company's  Credit  Facility.  In  February  1998,  the  Company  issued  an
additional  $50  million   aggregate   principal  amount  of  Reset  Notes  (the
"Additional  Reset  Notes").  Net proceeds  from the offering of the  Additional
Reset Notes were used to reduce  amounts  outstanding  under the Company's  bank
credit  facility and for general  business  purposes.  The Reset Notes currently
bear  interest  at a floating  rate equal to three  month LIBOR plus a spread of
 .45% per annum.  In July 1998,  the  Company  will have the option to prepay the
Reset Notes or to have the Reset Notes remarketed and the interest rate reset on
either a floating or fixed rate basis.

         In July 1997, the Company's  $250 million  unsecured  revolving  credit
facility with a syndicate of banks was  increased to $450 million,  and in March
1997, the term of the Credit  Facility was extended to 2001.  (See  "--Borrowing
Policy" above.)

         In  December  1997,  the Company  issued $150  million of 6 3/4% Senior
Notes due 2002 (the "6 3/4%  Notes")  in a private  placement  to  institutional
investors.  The net proceeds from the offering (approximately $149 million) were
used to reduce amounts then outstanding under the Company's Credit Facility. The
Company has agreed with the  initial  purchasers  of the 6 3/4% Notes to use its
best efforts to  consummate  an offer to exchange the 6 3/4% Notes for new notes
with terms substantially identical in all material respects to the 6 3/4% Notes,
which would be registered pursuant to the Securities Act.

Other Developments

         Horizon/CMS  Healthcare  Corporation;   HEALTHSOUTH  Corporation;   and
Integrated  Health  Services,  Inc. As of  December  31,  1997,  the Company had
invested approximately $168 million, at cost, in properties that had been leased
by, mortgaged to or managed by Horizon/CMS  Healthcare  Corporation  ("HHC"). In
October 1997, HHC merged into HEALTHSOUTH Corporation ("HEALTHSOUTH"). In return
for the  Company's  consent  to this  merger,  HEALTHSOUTH  agreed to  guarantee
unconditionally all of the lease, mortgage and management obligations of HHC due
to the  Company  and to extend the terms of the  management  contracts  of three
properties  that were  scheduled to expire  during 1998 until 2001.  In December
1997, HRP consented to the release of HEALTHSOUTH  from the guarantee and to the
assignment of certain leases and mortgages from HEALTHSOUTH and its predecessor,
HHC, to  Integrated  Health  Services,  Inc.  ("IHS") as part of a $1.2  billion
transaction between  HEALTHSOUTH and IHS for nursing homes,  specialty hospitals
and pharmacy services.  In connection with this consent,  IHS guaranteed leases,
mortgages and management obligations to HRP affecting the former HHC properties,
and the maturities of these leases, mortgages and management obligations,  which
were previously scheduled for 2000, 2001 and 2005, were extended to 2006.

         GranCare,  Inc.;  Living  Centers of America,  Inc.; and Paragon Health
Network,  Inc. As of December 31, 1997,  the Company had invested  approximately
$98 million,  at cost, in  properties  that had been leased to, or mortgaged by,
GranCare,  Inc. ("GC"). In February 1997, GC distributed to its shareholders all
of its nursing home  operations and merged its pharmacy  business into Vitalink,
Inc.  ("Vitalink"),  another public company.  Under the terms of the GC Vitalink
agreement,  the GC nursing home  operations  became a new public  company  ("New
GC"), and certain  subsidiaries of New GC remained  tenants of and mortgagors to
the Company (the "Tenant

                                       4
<PAGE>
Subsidiaries"). The Company consented to this GC Vitalink transaction on certain
terms and conditions, including: (i) all of the leases and mortgages between the
Company and the Tenant Subsidiaries being cross defaulted, cross collateralized,
cross secured and unconditionally  guaranteed by New GC; (ii) Vitalink providing
a $15 million unconditional guarantee of the obligations due to the Company; and
(iii) GC paying an amendment fee to the Company.  In October 1997, New GC merged
into Living Centers of America, Inc. ("LCA"), another public company. As part of
the  New GC LCA  transaction  a large  number  of LCA  and  New GC  shares  were
repurchased,  LCA was  recapitalized  by new investors,  the combined New GC LCA
enterprise  changed its name to Paragon Health Network,  Inc.  ("Paragon"),  and
Paragon solicited the Company to release Vitalink from its guaranty  obligations
to the Company.  The Company consented to the New GC LCA Paragon transaction and
released Vitalink from its guaranty on certain terms and conditions,  including:
(a) certain mortgage obligations totaling approximately $11.5 million due to the
Company being prepaid in full; (b) certain  properties  owned by the Company and
leased to the Tenant  Subsidiaries being exchanged for other properties formerly
owned by LCA or the Tenant  Subsidiaries,  which properties were to be leased to
the Tenant  Subsidiaries;  (c) the term of certain leases being extended and all
renewal options for properties leased to the Tenant Subsidiaries being renewable
only  on an all or none  basis;  (d)  the  rent  payable  to the  Company  being
increased; (e) all obligations with respect to all properties leased or financed
with the Tenant  Subsidiaries being guaranteed by Paragon and the guaranty being
secured by a cash  deposit of $15  million;  (f) all  obligations  of the Tenant
Subsidiaries  being  subject to cross default and cross  collateralization,  and
guaranteed  by New GC (now a  subsidiary  of  Paragon);  and (g)  payment to the
Company of an amendment fee.

         Community Care of America, Inc. and Integrated Health Services, Inc. As
of December 31, 1997, the Company had invested  approximately  $112 million,  at
cost, in properties  that had been operated by Community  Care of America,  Inc.
("CCA").  In September  1997, CCA was acquired by IHS. The Company  consented to
IHS's  acquisition  of  CCA on  certain  terms  and  conditions  including:  (i)
mortgages due to the Company totaling  approximately $12.2 million being prepaid
in full; (ii) certain properties formerly leased to CCA being purchased from the
Company at their  historical  cost of  approximately  $33.5  million;  (iii) the
extension of terms of certain remaining leases and mortgages; (iv) the remaining
leases and mortgages being subject to cross default and cross collateralization,
and  unconditionally  guaranteed  by IHS;  and (v)  payment to the Company of an
amendment fee.

         Marriott Spin Off and Merger.  As of December 31, 1997, the Company had
invested  approximately  $326  million,  at  cost,  in  properties  leased  to a
subsidiary  of  Marriott  International,  Inc.  ("Marriott").  In October  1997,
Marriott  announced a plan to dividend to its  shareholders  a new company which
will own and operate  Marriott's  lodging and senior  living  businesses  and to
merge the  remaining  company with Sodexho S.A. As a result of this spin off and
merger the Company's current guarantor was expected to have a negative net worth
and its  obligations  were not  expected  to be  rated  investment  grade.  Upon
learning of this planned  transaction,  the Company commenced  negotiations with
Marriott and, as a result of those  negotiations,  an agreement has been entered
into that will be  effective  upon  consummation  of the  Marriott  spin off and
merger transaction.  This agreement requires that the spin off entity created by
Marriott  assume the  guarantee  obligations  to the  Company.  The new spin off
entity is expected to be investment grade rated.

         In May  1997,  the  Company  filed a $1.0  billion  Shelf  Registration
Statement  on Form S-3 (the  "Shelf")  that has been  declared  effective by the
Securities  and  Exchange  Commission.  At March 1,  1998,  $539.7  million  was
available to be drawn on the Shelf.

The Investment Manager

         RMR is a Delaware  corporation  owned by Gerard M.  Martin and Barry M.
Portnoy.  RMR's  principal  executive  offices are located at 400 Centre Street,
Newton,  Massachusetts 02158, and its telephone number is (617) 332-3990.  As of
January 1, 1998,  the  Company  entered  into  separate  investment  advisor and
property management  agreements with RMR. RMR provides  investment,  management,
property  management  services  for  some of the  recently  acquired  Government
Properties and medical and other office buildings and administrative services to
the Company.  In addition,  an affiliate of RMR also provides garage  management
services to the Company.  During the three years ended  December 31, 1997,  such
services were provided by Advisor,  and M&P Partners Limited Partnership ("M&P")
on similar terms.  RMR also acts as the investment  manager to HPT and has other
business interests.  The Directors of RMR are Gerard M. Martin, Barry M. Portnoy
and David J. Hegarty.  The officers of RMR are David J.  Hegarty,  President and
Secretary,  John G. Murray, Executive Vice President, John Popeo, Treasurer, and
Ajay Saini, John A. Mannix, David Lepore and Thomas M. O'Brien, Vice Presidents.
Gerard M. Martin and Barry M. Portnoy are  Managing  Trustees of the Company and
David J.  Hegarty and Ajay Saini are

                                       5
<PAGE>

officers of the  Company.  The  beneficial  ownership  of Advisor  (which is the
General Partner of M&P) and M&P is the same as that of RMR and immediately prior
to January 1, 1998, the directors and officers of Advisor were the same as those
who currently hold positions with RMR.

Employees

         As of  March  5,  1998,  the  Company  had  no  employees.  RMR,  which
administers  the  day-to-day  operations  of  the  Company,  has  111  full-time
employees and three active directors.

Regulation and Reimbursement

         Compliance  with  federal,  state and local  statutes  and  regulations
governing  health care  facilities  is a  prerequisite  to  continuation  of the
Company's business.  The health care industry depends significantly upon federal
and  federal/state  programs for revenues and, as a result, is vulnerable to the
budgetary policies of both the federal and state governments.

Certificates  of Need.  Certain of the Company's  investments  are in healthcare
properties  which require  certificates  of need ("CONs")  prior to expansion of
beds or services, certain capital expenditures,  and in some states, a change in
ownership.  CON  requirements  are not  uniform  throughout  the United  States.
Changes  in  CON  requirements  may  affect  competition,  profitability  of the
Properties  and the  Company's  opportunities  for  investment  in  health  care
facilities.

Federal Regulation. The Company's healthcare properties are affected by a number
of  federal  and state  statutes  and  regulations  including  those  related to
reimbursement  under  Medicare and  Medicaid  programs.  Such laws,  among other
things,  limit  reimbursement  for capital costs and in some  circumstances  for
rental or lease expenses.  Such laws also include  federal and state  anti-fraud
and  anti-kickback  statutes and  regulations.  The Balanced  Budget Act of 1997
(Public Law 105-33)  (the "BBA")  directs the federal  Department  of Health and
Human  Services  ("HHS")  to adopt a  Medicare  prospective  payment  system for
skilled nursing  facilities which will include  capital-related  costs and which
will be phased in over four years beginning July 1, 1998. The BBA also increases
states'  flexibility  in  establishing   Medicaid  rates  for  nursing  facility
services, and strengthens the ability of HHS and the states to exclude providers
for health  care-related  offenses.  An  adverse  determination  concerning  any
operator's  licensure  or  eligibility  for  government   reimbursement  or  its
compliance  with  applicable  federal or state  statutes  on  regulations  could
materially and adversely affect such operator and its affiliates.

         A number of  legislative  proposals  that would affect major reforms of
the health care system have been introduced in Congress.  Such proposals include
universal health coverage,  employer mandated insurance, and a single government
health  insurance  plan.  Following the failure of the Clinton  administration's
proposed  Health  Security Act or other major health care reform  legislation to
become law in 1994, legislative proposals for more incremental reforms have also
been  introduced,  such as group health  insurance  plans for small  businesses,
health insurance industry reforms,  and additional Medicare and Medicaid reforms
and cost containment measures, including proposals that Medicaid be administered
through  block  grants to the  states and per  capita  limits on state  Medicaid
spending. The Company cannot predict whether any such legislative proposals will
be adopted or, if adopted, what effect, if any, such proposals would have on the
business of the Company or its lessees or mortgagors.

Competition.

         The Company competes with other real estate  investment  trusts in that
each is continually seeking attractive  investment  opportunities in health care
facilities and other types of real estate. The Company also competes with banks,
non-bank finance companies, leasing companies and insurance companies.

                        FEDERAL INCOME TAX CONSIDERATIONS

         The Company has elected to be taxed as a Real Estate  Investment  Trust
("REIT") under Sections 856 through 860 of the Internal Revenue Code of 1986, as
amended  and in  effect  from  time to time (the  "Code"),  commencing  with its
taxable  year  ending  December  31,  1987.  The  Company  believes  it has been
organized  and has operated in a manner that  qualifies it to be taxed under the
Code as a REIT  commencing  with that taxable year,  and the Company  intends to
continue  to  operate  in a manner to so  qualify.  No  assurance  can be given,
however,  that the manner in which the  Company  has  operated  or will  operate
qualified or will qualify the Company to be taxed as a REIT.

         The Company has obtained  legal  opinions  from its counsel  Sullivan &
Worcester  LLP that  the  Company  has been  organized  in  conformity  with the
requirements for  qualification as a REIT, has qualified as a REIT for its 1987,
1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996 and 1997 taxable years, and
that its current and  anticipated  investments  and its plan of  operation  will
enable it to continue to meet the requirements for qualification and taxation as
a REIT under the Code.  These opinions are conditioned  upon the assumption that
the  leases,  the  Declaration  and the  Company's  Bylaws,  and all other legal
documents  to which  the  Company  is or has been a party  have been and will be
complied with by all parties thereto,  upon the accuracy and completeness of the
factual matters described in this Annual Report, and upon  representations  made
by  the  Company  as to  certain  factual  matters  relating  to  the  Company's
organization  and operations and its expected manner of operation.  In addition,
such  opinions  are  based on the law then  existing  and in  effect on the date
thereof.  Opinions of counsel are not binding on the  Internal  Revenue  Service
("IRS")  or a court and there can be no  assurance  that the IRS or a court will
not take a position different from that expressed by counsel.

         The Company's actual  qualification  and taxation as a REIT will depend
upon  the  Company's  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 Code,
discussed below. While the Company has represented that it has operated and will
operate in a manner so as to  satisfy on a  continuing  basis the  various  REIT
qualification  tests,  Sullivan & Worcester  LLP has not  reviewed  and will not
review  compliance with these tests on a continuing  basis, and no assurance can
be given  that  the  Company  has  satisfied  or will  satisfy  such  tests on a
continuing basis. If the Company fails to qualify as a REIT in any year, it will
be subject to federal income taxation as if it were a domestic corporation,  and
its  shareholders  will be taxed in the same manner as  shareholders of ordinary
corporations.  In such an event,  the  Company  could be subject to  potentially
significant  tax  liabilities,  and therefore  the amount of cash  available for
distribution to its shareholders would be reduced or eliminated.

         The following summary is based on existing law, is limited to investors
who will hold the Shares as "capital  assets" within the meaning of Section 1221
of the Code (generally,  property held for investment), 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 holders of Shares who may
be subject to  special  rules  under the  federal  income tax law,  such as life
insurance companies,  regulated investment  companies,  financial  institutions,
brokers or dealers  in  securities  or  foreign  currency,  persons  that have a
functional  currency other than the U.S. dollar,  persons who acquired Shares or
options  to  acquire  Shares  in  connection  with  their  employment  or  other
performance of services, persons subject to alternative minimum tax, persons who
hold  Shares  as  part  of  a  straddle,  hedging  transaction,   or  conversion
transaction or, except as specifically described herein, tax-exempt entities and
foreign  persons.  The  sections of the 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 Code provisions,  the rules and regulations  promulgated  thereunder,
and the administrative and judicial  interpretations  thereof,  all of which are
subject to change,  possibly with retroactive effect.  Thus, no assurance can be
given that future legislative,  judicial, or administrative actions or decisions
will not affect the accuracy of any statements in this summary. In addition,  no
ruling has been or is  expected  to be sought  from the IRS with  respect to any
matter discussed  herein,  and there can be no assurance that the IRS or a court
will agree with the statements  made herein.  Accordingly,  each  shareholder is
urged to consult his own tax advisor with respect to the federal  income tax and
other tax consequences of the purchase, holding and sale of Shares.

         Taxation of the  Company.  If the Company  qualifies  for taxation as a
REIT and  distributes  to its  shareholders  at least  95% of its  "real  estate
investment  trust taxable income"  (determined by excluding any net capital gain
and before taking into account any dividends paid deduction),  it generally will
not be subject to federal corporate income taxes on the amount distributed. This
deduction  for  dividends  paid to  shareholders  substantially

                                       7
<PAGE>
eliminates  the federal  "double  taxation" on earnings  (once at the  corporate
level  and  again at the  shareholder  level)  that  generally  results  from an
investment in a corporation.

         However, even if the Company qualifies for federal income taxation as a
REIT,  it may be subject to federal  tax in certain  circumstances.  First,  the
Company  will be taxed at regular  corporate  rates on any  undistributed  "real
estate  investment trust taxable income,"  including  undistributed  net capital
gains.  Second, under certain  circumstances,  the Company may be subject to the
corporate  "alternative  minimum  tax" on its items of tax  preference,  if any.
Third,  if the Company has (i) net income from the sale or other  disposition of
"foreclosure  property"  (generally,  property  acquired by the Company  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 (ii) other nonqualifying  income from foreclosure
property,  then the Company will be subject to tax on such income at the highest
regular  corporate rate (currently 35%).  Fourth,  if the Company has 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),  such  income  will be
subject to tax at a 100% rate.  Fifth, if the Company should fail to satisfy the
75% gross  income  test or the 95% gross  income  test  (discussed  below),  but
nonetheless  maintains  its  qualification  as  a  REIT  because  certain  other
requirements  are met,  the Company will be subject to tax at a 100% rate on the
greater  of the  amount  by which  the  Company  fails  the 75% or the 95% test,
multiplied by a fraction intended to reflect the Company's profitability. Sixth,
if the Company  should fail to distribute for any calendar year at least the sum
of (i) 85% of its  REIT  ordinary  income  for such  year,  (ii) 95% of its REIT
capital  gain net  income  for such year,  and (iii) any  undistributed  taxable
income from prior periods, the Company will be subject to a 4% excise tax on the
excess of such  required  distribution  over the amounts  actually  distributed.
Seventh,  if the Company acquires any asset from a C corporation  (generally,  a
corporation  subject to full corporate  level tax) in a transaction in which the
basis of the asset in the  Company's  hands is  determined  by  reference to the
basis  of the  asset  in the  hands  of the C  corporation,  and if the  Company
subsequently  recognizes  gain on the  disposition  of  such  asset  during  the
ten-year  period  beginning  on the date on which the asset was  acquired by the
Company, then the Company will pay tax at the highest regular corporate tax rate
(currently  35%) on the lesser of (i) the excess of the fair market value of the
asset over the Company's  basis in the asset on the date acquired by the Company
and (ii) the gain recognized by the Company.

         If the Company  should invest in properties in foreign  countries,  the
Company's  profits from such investments will generally be subject to tax in the
countries where such  properties are located.  The nature and amount of any such
taxation  will  depend on the laws of the  countries  where the  properties  are
located.  If the Company  satisfies  the annual  distribution  requirements  for
federal  income tax  qualification  as a REIT and is  therefore  not  subject to
federal  corporate income tax on that portion of its ordinary income and capital
gain  that is  currently  distributed  to its  shareholders,  the  Company  will
generally  not be able to recover the cost of any foreign tax imposed on profits
from its foreign investments by claiming foreign tax credits against its federal
income  tax  liability  on such  profits.  Moreover,  a REIT is not able to pass
through to its shareholders any foreign tax credits.

         The Company's  Wholly-Owned  Subsidiaries.  Section  856(i) of the Code
provides that a corporation that is a qualified REIT subsidiary  (defined as any
corporation  100% of whose  stock is held by the REIT at all  times  during  the
period  the  corporation  is in  existence)  shall not be  treated as a separate
corporation,  and all assets,  liabilities,  and items of income, deduction, and
credit of a qualified REIT  subsidiary  shall be treated as assets,  liabilities
and items of  income,  deduction,  and  credit of the REIT.  (For the  Company's
taxable years commencing on or after January 1, 1998, a wholly-owned corporation
qualifies as a qualified REIT  subsidiary even though there was a period of time
during which the Company did not own 100% of its stock; such corporation will be
treated for federal income tax purposes as though liquidated into the Company at
the time the Company  acquired 100% ownership,  and then  reincorporated  by the
Company as a qualified REIT  subsidiary.)  The Company believes that each of its
direct and indirect  wholly-owned  subsidiaries  qualifies either as a qualified
REIT  subsidiary  within  the  meaning of  Section  856(i) of the Code,  or as a
noncorporate  entity  that for  federal  income tax  purposes  is not treated as
separate from its owner pursuant to Treasury  Regulations  under Section 7701 of
the Code.  Thus,  in  applying  all the  federal  income tax REIT  qualification
requirements  discussed herein,  the Company's 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 assets,  liabilities
and items of income, deduction and credit of the Company.

         The  Company's  Investments  through  Partnerships.   The  Company  has
invested,  and in the future may  invest,  in real  estate  through  one or more
limited or general  partnerships or limited liability  companies that is treated
as a partnership for federal income tax purposes.  In the case of a REIT that is
a partner in a partnership,  Treasury  Regulations  provide that for purposes of
the REIT qualification requirements regarding income and assets discussed

                                       8
<PAGE>
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,   the  Company's
proportionate  share of the  assets,  liabilities,  and  items of income of each
partnership  in which it is a partner  are treated as assets,  liabilities,  and
items of income of the Company for  purposes of the income tests and asset tests
discussed below.  However,  for purposes of the REIT's distribution  requirement
discussed  below,  a REIT must take into  account as a partner its  distributive
share of the partnership's income as determined under the general federal income
tax rules governing  partners and partnerships under Sections 701 et seq. of the
Code.

         REIT Qualification Requirements--Generally.  Section 856(a) of the Code
defines a REIT as a corporation,  trust or association:  (1) which is managed by
one or more  trustees or  directors;  (2) the  beneficial  ownership of which is
evidenced by transferable  shares or by transferable  certificates of beneficial
interest;  (3) which would be taxable,  but for  Sections 856 through 859 of the
Code, as a domestic  corporation;  (4) which is neither a financial  institution
nor an insurance  company  subject to certain  provisions  of the Code;  (5) the
beneficial  ownership of which is held by 100 or more persons;  (6) which is not
"closely held" as determined  under the personal holding company stock ownership
test (as applied with  modifications);  and (7) which meets  certain other tests
regarding income, assets, and distributions,  as described below. Section 856(b)
of the 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.  It is the Company's belief and expectation that it
has had and will have at least 100 shareholders  during the requisite period for
each of its taxable  years since its election to be taxed as a REIT.  There can,
however,  be no assurance in this  connection and, if the Company has fewer than
100 shareholders during the requisite period, condition (5) described above will
not be  satisfied,  and the  Company  would not  qualify as a REIT  during  such
taxable year.

         By reason of the "closely held"  condition (6) above,  the Company 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 its outstanding  Shares is owned directly
or indirectly by five or fewer  individuals.  To help maintain  conformity  with
condition (6), the Declaration contains certain provisions restricting transfers
of Shares and giving the Trustees the power to redeem Shares involuntarily.  For
its  taxable  years  commencing  on or after  January  1, 1998,  if the  Company
complies  with  Treasury  Regulations  for  ascertaining  the  ownership  of its
outstanding Shares and does not know or, exercising  reasonable  diligence would
not have  known,  whether it failed  condition  (6),  then the  Company  will be
treated as satisfying  condition (6). Also, for its taxable years  commencing on
or after  January 1, 1998,  the  Company's  failure to comply with the  Treasury
Regulations for ascertaining ownership of its outstanding Shares may result in a
penalty  of $25,000  ($50,000  for  intentional  violations).  Accordingly,  the
Company will, pursuant to the Treasury Regulations, request annually from record
holders of certain  significant  percentages of its Shares  certain  information
regarding the ownership of such Shares. Under the Declaration,  shareholders are
required to respond to such 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 such year more than 50% in value of
its  outstanding  shares  is  owned  directly  or  indirectly  by five or  fewer
individuals is relaxed in the case of certain  pension trusts owning shares in a
REIT. Shares in a REIT held by such a pension trust are treated as held directly
by its  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 its 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 its shares (by value) generally will
be taxable on a portion of the dividends it receives from the REIT, based on the
ratio of the REIT's gross income for the year which would be unrelated  trade or
business  income if the REIT were a qualified  pension trust to the REIT's total
gross income for the year.

         To qualify as a REIT under the Code,  the  Company  must elect to be so
treated and must meet other requirements, certain of which are summarized below,
including  percentage  tests  relating to the sources of its gross  income,  the
nature of its assets,  and the distribution of its income to  shareholders.  The
Company made such an election for 1987 (its first full year of operations),  and
such  election,  assuming  continuing  compliance  with the  federal  income tax
qualification tests discussed herein, continues in effect for subsequent years.

         Income Tests.  There are three gross income  requirements,  only two of
which apply to the Company for its taxable years  commencing on or after January
1, 1998.  First,  at least 75% of the Company's  gross income

                                       9
<PAGE>
(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"),  mortgages on real property, or
shares in other REITs. When the Company receives new capital in exchange for its
Shares (other than  dividend  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 the  Company's  receipt  of the new  capital,  is
qualifying  income  under the 75% test.  Second,  at least 95% of the  Company's
gross  income  (excluding  gross  income from  certain  sales of  property  held
primarily  for  sale)  must be  derived  from such  real  property  investments,
dividends, interest, certain payments under interest rate swap or cap agreements
(and for the  Company's  taxable  years  commencing on or after January 1, 1998,
certain payments under options, futures contracts,  forward rate agreements,  or
similar financial instruments),  and gain from the sale or disposition of stock,
securities,  or real property, or from any combination of the foregoing.  Third,
for  the  Company's  taxable  years  ending  on or  before  December  31,  1997,
short-term  gain  from  the  sale or other  disposition  of stock or  securities
(including,  without limitation, stock in other REITs), dispositions of interest
rate swap or cap agreements,  and gain from certain  prohibited  transactions or
other  dispositions  of real  property held for less than four years (apart from
involuntary conversions and sales of foreclosure property) must have represented
less than 30% of the Company's  gross income.  For purposes of these three 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.  Even  though the  Company  does not own  mortgage
loans that contain shared appreciation provisions, the Company may in the future
make such mortgage  loans.  The Company  temporarily  invests working capital in
short-term  investments,  including shares in other REITs.  Although the Company
will use its best efforts to ensure that the income generated by its investments
will be of a type which satisfies the 75% and 95% gross income tests,  there can
be no assurance in this regard.

         In order to qualify as "rents from real property," 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 Code  provides  that  rents will not  qualify  as "rents  from real
property" in  satisfying  the gross income tests if the REIT owns 10% or more of
the tenant,  whether  directly or under certain  attribution  rules. The Company
intends not to lease property to any party if rents from such property would not
so qualify.  Application of the 10% ownership rule is,  however,  dependent upon
complex  attribution  rules and upon  circumstances  beyond  the  control of the
Company.  Ownership,  directly or by attribution, by an unaffiliated third party
of more than 10% of the Shares and more than 10% of the stock of a lessee  would
result in lessee  rents  not  qualifying  as  "rents  from real  property."  The
Declaration  provides that transfers or purported  acquisitions,  directly or by
attribution, of Shares that could result in disqualification of the Company as a
REIT are null and void and permits  the  Trustees  to  repurchase  Shares to the
extent necessary to maintain the Company's status as a REIT. Nevertheless, there
can be no assurance  such  provisions  in the  Declaration  will be effective to
prevent the Company's  REIT status from being  jeopardized  under the 10% lessee
affiliate rule. Furthermore,  there can be no assurance that the Company will be
able to monitor and enforce such restrictions, nor will shareholders necessarily
be aware of shareholdings attributed to them under the attribution rules. Third,
in order for its rents to qualify as "rents  from real  property,"  the  Company
must not manage the  property  or furnish or render  services  to the tenants of
such property,  except through an independent  contractor  from whom the Company
derives 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." For the Company's taxable years commencing on or after
January  1,  1998,  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 greater than 15% of the total rent received  under the
lease,  then the portion of rent attributable to such personal property will not
qualify as "rents from real  property."  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 which
is rented.  Substantially all of the gross income of the Company has been and is
expected to be attributable to rental income.  The Company  believes that all or
substantially  all such rents have  qualified  and will  continue  to qualify as
"rents from real  property" for purposes of Section 856 of the Code,  but if for
some  reason a  significant  amount of such rents do not so  qualify,  it may be
difficult  or  impossible  for the  Company 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 

                                       10
<PAGE>
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 the Company on the sale of any  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 the  Company's  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.  The Company  intends to hold its real estate assets for investment
with a view to long-term appreciation,  to engage in the business of developing,
owning and operating its existing real estate assets and acquiring,  developing,
owning  and  operating  other  real  estate  assets,   and  to  make  occasional
dispositions  of  real  estate  assets  as  is  consistent  with  the  Company's
investment  objectives.  There can be no assurance,  however, that the IRS might
not contend that one or more dispositions is subject to the 100% penalty tax.

         If the  Company  fails to  satisfy  one or both of the 75% or 95% gross
income tests for any taxable  year,  it may  nevertheless  qualify as a REIT for
such year if (i) the  Company's  failure to meet such test was due to reasonable
cause and not due to willful  neglect,  (ii) the Company reported the nature and
amount of each item of its income  included in the 75% or 95% gross income tests
(as the case may be) for such taxable year on a schedule attached to its return,
and (iii) any  incorrect  information  on the schedule was not due to fraud with
intent to evade tax. No similar provision  provides relief if the Company failed
the 30% gross income test for the taxable years such test was applicable, and it
is not  possible to state  whether in all  circumstances  the  Company  would be
entitled  to the  benefit  of the  relief  provisions  for the 75% and 95% gross
income tests. As discussed  above,  even if these relief  provisions do apply, a
special tax equal to 100% is imposed upon the greater of the amount by which the
Company failed the 75% test or the 95% test,  multiplied by a fraction  intended
to reflect the Company's profitability.

         Asset  Tests.  At the close of each  quarter of the  Company's  taxable
year,  it must also  satisfy  three tests  relating to the nature of its assets.
First,  at least 75% of the value of the Company's  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 the Company), cash, cash items,
shares in other REITs, and government  securities.  Second, not more than 25% of
the Company's  total assets may be represented  by securities  (other than those
includable in the foregoing 75% asset class). Third, of the investments included
in the foregoing 25% asset class, the value of any one issuer's securities owned
by the Company may not exceed 5% of the value of the Company's total assets, and
the Company  may not own more than 10% of any one  issuer's  outstanding  voting
securities.  President  Clinton has proposed  legislation that would expand this
last  prohibition  so that the Company  would not be  permitted to own more than
10%, either by vote or by value, of any one issuer's outstanding securities.

         Where a failure to satisfy the  foregoing  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 such quarter.  The Company intends to maintain  adequate records of the
value of its assets to maintain  compliance with the foregoing asset tests,  and
to take such  action 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 as a REIT, the
Company is required to distribute  dividends (other than capital gain dividends)
to its  shareholders  each year in an amount at least equal to the excess of (A)
the  sum of (i) 95% of the  Company's  "real  estate  investment  trust  taxable
income" (computed without regard to the dividends paid deduction and net capital
gain) and (ii) 95% of the net  income  (after  tax),  if any,  from  foreclosure
property,  over (B) the sum of certain  noncash  income (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
the Company  timely  files its tax return for such  earlier  taxable year and if
paid on or before the first regular  dividend  payment  after such  declaration.
Also, dividends declared in October,  November,  or December and paid during the
following  January  will be treated as having been paid and received on December
31. A distribution  which is not pro rata within a class of beneficial  interest
in the  Company  entitled  to a dividend,  or which is not  consistent  with the
rights to distributions  between classes of beneficial interests in the Company,
is a preferential  dividend that is not taken into consideration for purposes of
the  distribution  requirement,  and  accordingly  the payment of a preferential
dividend   could  affect  the  Company's   ability  to  meet  the   distribution
requirement.  Taking into account the Company's distribution policies

                                       11
<PAGE>
(including its dividend reinvestment plan), the Company believes that it has not
made and  expects  that it will not make  any such  preferential  dividend.  The
distribution  requirements may be waived by the IRS if the REIT establishes that
it failed to meet them by reason of  distributions  previously  made to meet the
requirements  of the 4% excise  tax  discussed  below.  To the  extent  that the
Company  does not  distribute  all of its net capital  gain and all of its "real
estate investment trust taxable income," as adjusted,  it will be subject to tax
thereon.

         In  addition,  the  Company  will be  subject to a 4% excise tax to the
extent it fails within a calendar year to make "required  distributions"  to its
shareholders  of 85% of its  ordinary  income  and 95% of its  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 such
preceding  calendar  year.  For this  purpose,  the term  "grossed  up  required
distribution"  for any  calendar  year is the sum of the  taxable  income of the
Company 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 the  Company,  from  time to  time,  may not have
sufficient cash or other liquid assets to meet the 95% distribution requirements
due to timing  differences  between (i) the actual  receipt of income and actual
payment of deductible  expenses or distributions  and (ii) the inclusion of such
income and  deduction  of such  expenses or  distributions  in arriving at "real
estate  investment  trust  taxable  income"  of  the  Company.  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 the  Company's  outstanding
debt, particularly in the case of "balloon" repayments or as a result of capital
losses on short-term  investments  of working  capital.  Therefore,  the Company
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 its REIT status for federal income tax purposes could be
jeopardized. There can be no assurance that such borrowing or financing would be
available on favorable terms.

         Under  certain  circumstances,  the  Company  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 the
Company's  deduction  for  dividends  paid for the  earlier  year,  although  an
interest charge would be imposed upon the Company for the delay in distribution.
Although  the  Company  may  thus  be able  to  avoid  being  taxed  on  amounts
distributed as deficiency  dividends,  the Company may in certain  circumstances
remain liable for the 4% excise tax discussed above.

         For its  taxable  years  ending on or before  December  31,  1997,  the
Company  was  required  to  request  annually  from  record  holders  of certain
significant   percentages  of  its  Shares  certain  information  regarding  the
ownership of such Shares,  in order to qualify for the  deduction  for dividends
paid to its shareholders. As discussed above, for taxable years commencing on or
after January 1, 1998, the Company will continue to request such  information in
order to comply  with the REIT  qualification  requirement  regarding  ownership
concentration of its Shares.

         Federal Income Tax Treatment of Leases. The availability to the Company
of, among other things,  depreciation  deductions with respect to the facilities
owned and leased by the Company will depend upon the treatment of the Company as
the  owner  of the  facilities  and  the  classification  of the  leases  of the
facilities as true leases, rather than as sales or financing  arrangements,  for
federal income tax purposes.  As to the approximately 2% of the Company's leased
facilities which constitutes  personal  property,  it is not entirely clear that
the Company 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. The Company
plans to insure its compliance with the 95%  distribution  requirement  (and the
excise tax "required  distribution"  requirement) by making distributions on the
assumption that it is not entitled to depreciation  deductions for the 2% of the
leased facilities which constitute personal property, but to perform all its tax
reporting by taking into account such depreciation.

         In the  case of  certain  sale-leaseback  arrangements,  the IRS  could
assert that the Company  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  the  Company  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 clear  precedent,  complete  assurance
cannot be given  that the IRS could not  successfully  assert the  existence  of
prepaid rental income.

                                       12
<PAGE>
         Additionally,  it  should  be  noted  that  Section  467  of  the  Code
(concerning leases with increasing rents) would apply to the leases because many
of the  leases  provide  for rents  that  increase  from one period to the next.
Section 467 of the Code provides  that in the case of a so-called  "disqualified
leaseback  agreement," rental income must be accrued at a constant rate. If such
constant rent accrual were required,  the Company could recognize  rental income
in excess of cash  rents  and,  as a result,  may fail to meet the 95%  dividend
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
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 of the leases  generally
should  not  cause the  leases to be  "disqualified  leaseback  agreements."  In
addition,  the legislative history of Section 467 of the 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,  the
Company generally depreciates its real property on a straight-line basis over 40
years and its personal property over 12 years.

         Failure to Qualify.  If the Company fails to qualify for federal income
taxation as a REIT in any taxable year, and any  potentially  applicable  relief
provisions  do not apply,  the  Company  will be  subject to tax on its  taxable
income  at  regular   corporate   rates  (plus  any  applicable   minimum  tax).
Distributions  to shareholders in any year in which the Company fails to qualify
will not be  deductible  by the Company nor will they be required to be made. In
such event, to the extent of the Company's current and accumulated  earnings and
profits,  all  distributions to shareholders will be taxable as ordinary income,
and  subject  to  certain  limitations  in the  Code  will be  eligible  for the
dividends received  deduction for corporations.  Unless entitled to relief under
specific  statutory  provisions,  the  Company  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 the Company would be entitled
to statutory relief from such disqualification.  Failure to qualify for even one
year could result in the Company's  incurring  substantial  indebtedness (to the
extent borrowings are feasible) or liquidating  substantial investments in order
to pay the resulting taxes.

         Taxation  of U.S.  Shareholders--Generally.  As used  herein,  the term
"U.S.  Shareholder"  means a  beneficial  holder of Shares  that is for  federal
income tax  purposes  (i) a citizen or  resident  of the United  States,  (ii) 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 or of any political  subdivision  thereof  (unless
otherwise provided by Treasury Regulations), (iii) an estate the income of which
is subject to federal income taxation  regardless of its source, or (iv) 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 herein, the term "Non-U.S. Shareholder" means a beneficial
holder of Shares that is not a U.S. Shareholder.

         As long as the  Company  qualifies  as a REIT for  federal  income  tax
purposes,  distributions  (including  reinvestments  pursuant  to the  Company's
dividend  reinvestment  plan) made to the  Company's  U.S.  Shareholders  out of
current or  accumulated  earnings and profits will be taken into account by them
as  ordinary  income  (but  will  not be  eligible  for the  dividends  received
deduction for corporations).  Distributions that are properly  designated by the
Company as capital gain dividends  will be taxed as long-term  capital gains (as
discussed  below) to the  extent  they do not exceed  the  Company's  actual net
capital gain for the taxable year,  although corporate U.S.  Shareholders may be
required to treat up to 20% of any such capital gain dividend as ordinary income
pursuant to Section 291 of the Code. For the Company's  taxable years commencing
on  or  after  January  1,  1998,  the  Company  may  elect  to  retain  amounts
representing  its net capital  gain  income.  In that case,  the Company will be
taxed at regular  corporate  capital gains tax rates on such amounts,  each U.S.
Shareholder  will be taxed on its  proportionate  share of the net capital gains
retained by the Company as though such amount were  distributed and designated a
capital gain dividend,  and each such U.S. Shareholder will receive a credit for
a proportionate  share of the tax paid by the Company.  Additionally,  each U.S.
Shareholder  will increase the adjusted basis in its 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 the Company, and both the Company and its
corporate  U.S.  Shareholders  will  make  commensurate   adjustments  in  their

                                       13
<PAGE>
respective earnings and profits for federal income tax purposes.  If the Company
should elect to retain its net capital gain in this fashion, it will notify each
U.S.  Shareholder of the relevant tax information within 60 days after the close
of the Company's taxable year.

         For certain  noncorporate  U.S.  Shareholders,  long-term capital gains
taken into account after May 7, 1997 are taxed at varying  maximum rates of 20%,
25%, or 28%,  depending  upon the type of  property  disposed of and the holding
period in such property at the time of disposition.  If the Company designates a
dividend as a capital gain  dividend for any taxable year of the Company  ending
after May 7, 1997 (or  elects to retain a portion  of its net  capital  gain and
have such amount treated as a distributed  and designated  capital gain dividend
in the manner  described  above),  the Company may also designate the portion of
such  capital  gain  dividend  which  is  taxed  to  certain  noncorporate  U.S.
Shareholders  at the varying  maximum rates of 20%, 25%, or 28%,  based upon the
type and  holding  period of the  property  disposed of by the  Company.  If the
Company does not make such a designation,  the entire capital gain dividend will
be treated as  long-term  capital  gain  subject to the  maximum 28% rate to the
noncorporate U.S.  Shareholders (without regard to the period for which the U.S.
Shareholder held its Shares).

         For  purposes  of  computing  the   Company's   earnings  and  profits,
depreciation on real estate is generally computed on a straight-line  basis over
40 years. 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  Shares,  but will reduce the U.S.
Shareholder's basis in such Shares. To the extent that such distributions exceed
the  adjusted  basis of a U.S.  Shareholder's  Shares,  they will be included in
income as long-term capital gain (or short-term  capital gain if the shares have
been held for not more than one year), with such long-term gain taxed to certain
noncorporate U.S.  Shareholders at varying maximum rates of 20% or 28% depending
upon the U.S.  Shareholder's holding period in the Shares. U.S. Shareholders may
not include in their  respective  income tax returns any net operating losses or
capital losses of the Company.

         Dividends declared by the Company in October, November or December of a
taxable year to shareholders  of record on a date in such month,  will be deemed
to have been received by such  shareholders on December 31, provided the Company
actually pays such dividends during the following January. For tax purposes, the
Company's  dividends paid in 1987,  1988,  1989,  1990,  1991, 1992, 1993, 1994,
1995, 1996 and 1997 aggregated $1.085, $.840, $1.13, $1.16, $1.22, $1.25, $1.29,
$1.32, $1.37, $1.41 and $1.45 respectively, of which $.289, $.065, $.332, $.267,
$.104, $.218, $.335, $.081, $.161, $.350 and $.252, respectively,  represented a
return of capital.

         The sale or exchange of 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 its adjusted basis in the Shares sold or exchanged.  Such a
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 Shares exceeded one year.
Long-term capital gains may be taxed to certain  noncorporate U.S.  Shareholders
at varying  maximum  rates of 20% or 28% depending  upon the U.S.  Shareholder's
holding period in the Shares.  In addition,  any loss upon a sale or exchange of
Shares  by a U.S.  Shareholder  who has held such  Shares  for not more than six
months (after applying certain rules),  will generally be treated as a long-term
capital  loss to the extent of  distributions  from the  Company  required to be
treated by such U.S. Shareholders as long-term capital gain (including, for this
purpose,  amounts  constructively  distributed as long-term  capital gain by the
Company electing to retain its net capital gain in the manner described above).

         U.S. Shareholders (other than certain corporations) who borrow funds to
finance  their  acquisition  of Shares in the  Company  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 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
dividend  distributions  and, if an appropriate  election is made,  capital gain
dividend  distributions  it receives  from the Company;  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 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  received  by a U.S.  Shareholder  from  the  Company  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  which are  treated  differently  for
regular and alternative  minimum tax purposes are to be allocated between a REIT
and  its  shareholders  under  regulations  which  are to be  prescribed.  It is

                                       14
<PAGE>
possible  that  these  regulations  would  require  tax  preference  items to be
allocated  to  the  Company's  shareholders  with  respect  to  any  accelerated
depreciation  claimed by the  Company;  however,  the  Company  has not  claimed
accelerated depreciation with respect to its existing 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 Revenue Ruling
66-106  and the  analysis  therein,  distributions  made by the  Company 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  such  U.S.  Shareholder  has  financed  the
acquisition of its Shares with "acquisition  indebtedness" within the meaning of
the Code,  or the 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" at any time during a taxable year commencing after December 31, 1993. Such
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. Such percentage is equal to the ratio of the pension-held REIT's
gross income (less direct expenses  related thereto) derived from the conduct of
unrelated trades or businesses  (determined as if the  pension-held  REIT were a
tax-exempt  pension fund), to the pension-held  REIT's gross income (less direct
expenses related thereto) from all sources, except that such percentage shall be
deemed to be zero unless it would  otherwise  equal or exceed 5%. A REIT will be
treated as a pension-held REIT only if (i) the REIT is  "predominantly  held" by
tax-exempt pension trusts, and (ii) the REIT would otherwise fail to satisfy the
"closely  held"  ownership  conditiondiscussed  above if the stock or beneficial
interests in the REIT held by such tax-exempt pension trusts were viewed as held
by such tax-exempt pension trusts rather than 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.
Given the restrictions in its Declaration regarding ownership of its Shares, the
Company  believes  that it has not  been,  and  expects  that it will  not be, a
pension-held REIT.  However,  because the Shares of the Company will be publicly
traded,  no  assurance  can  be  given  that  the  Company  will  not  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 such 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 the
Company.  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 Shares if such  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 Code,
which is payable in  addition  to regular  federal  corporate  income  tax.  The
following  discussion  addresses only Non-U.S.  Shareholders whose investment in
Shares is not  effectively  connected with the conduct of a trade or business in
the United States.

         A  distribution  by the Company to a Non-U.S.  Shareholder  that is not
attributable to gain from the sale or exchange by the Company of a United States
real  property  interest and that is not  designated by the Company 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, such a
dividend will be subject to federal income  withholding  tax on the gross amount
thereof at the rate of 30%, or such lower rate that may be  specified  by treaty
if the Non-U.S. Shareholder has in the manner prescribed by the IRS demonstrated
to the Company its  entitlement to treaty  benefits.  A distribution  of cash in
excess  of the  Company's  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 Shares  (but not below zero) and then as gain from the  disposition  of such
Shares,  the tax treatment of which is discussed below. A distribution in excess
of the  Company's  earnings  and profits may be subject to 30% (or 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 the Company's current
and 

                                       15
<PAGE>
accumulated  earnings and profits.  If it is  subsequently  determined that such
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. The Company
expects to withhold  federal  income  withholding  tax at the rate of 30% on the
gross  amount of any  distributions  on Shares  made to a  Non-U.S.  Shareholder
unless  a  lower  tax  treaty  applies  and the  required  IRS  form  evidencing
eligibility for that reduced rate is filed with the Company.

         For any year in which the Company qualifies as a REIT, distributions by
the Company 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 such
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 such  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). Such distributions may also be subject to a 30% branch profits tax
under Section 884 of the Code in the hands of a corporate  Non-U.S.  Shareholder
that is not entitled to treaty relief or exemption. The Company 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
the Company designates prior distributions as capital gain  distributions,  then
subsequent distributions, up to the amount of such 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 the Company's  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 the  Company  with  respect to a  distribution  to a
Non-U.S.  Shareholder  exceeds such  shareholder's  federal income tax liability
with  respect to such  distribution,  the  Non-U.S.  Shareholder  may file for a
refund of such excess from the IRS. 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%,  25%, and 28% maximum rates on capital  gains  generally  applicable to
noncorporate  Non-U.S.  Shareholders.  Treasury Regulations issued on October 6,
1997 (the "New Regulations")  alter the withholding rules on dividends paid to a
Non-U.S.  Shareholder,  generally effective with respect to dividends paid after
December  31,  1998.  Under the New  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  such
Non-U.S.  Shareholder's  entitlement  to  benefits  under  the  treaty.  The New
Regulations  also provide  special rules to determine  whether,  for purposes of
determining  the  applicability  of a tax treaty,  dividends  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  such entity or such
holders in the entity are  entitled  to benefits  under the tax treaty.  The New
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 the Company  receives  certification  from such
shareholder of its Non-U.S. Shareholder status.

         If the  Shares  fail to  constitute  a  "United  States  real  property
interest"  within the  meaning of Section  897 of the Code,  gain on sale of the
Shares by a Non-U.S. Shareholder generally will not be subject to federal income
taxation  unless (i) investment in the 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 such  gain,  or (ii)  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 such gain.

         The Shares will not  constitute a United States real property  interest
if the Company is a "domestically  controlled  REIT." A domestically  controlled
REIT is a REIT in which at all times during the preceding  five-year period less
than 50% in value of its  shares  is held  directly  or  indirectly  by  foreign
persons.  It is believed  that the  Company  has been and will  continue to be a
domestically  controlled  REIT,  and  therefore  that  the sale of  Shares  by a
Non-U.S.  Shareholder will not be subject to federal income  taxation.  However,
because  the Shares are  publicly  traded,  no  assurance  can be given that the
Company has been and will continue to be a domestically  controlled REIT. If the
Company is not a domestically controlled REIT, whether a Non-U.S.  Shareholder's
gain on sale of Shares  would be subject  to  federal  income tax as a sale of a
United States real property  interest  would depend upon whether the Shares were
"regularly  traded"  (as  defined  by  applicable  Treasury  Regulations)  on an
established  

                                       16
<PAGE>
securities  market (e.g.,  the New York Stock Exchange,  on which the Shares are
listed) and upon the size of the selling Non-U.S.  Shareholder's interest in the
Company.  If the gain on the sale of the 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 such 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  Shares  from a  Non-U.S.
Shareholder  will not be  required  to  withhold  on the  purchase  price if the
purchased Shares are "regularly  traded" on an established  securities market or
if the Company is a domestically  controlled REIT.  Otherwise,  the purchaser of
Shares  may be  required  to  withhold  10% of the  purchase  price  paid to the
Non-U.S. Shareholder and to remit such amount to the IRS.

         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.  The Company
will report to its U.S. Shareholders and to the IRS the amount of dividends 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  dividends  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 the Company
with its  correct  taxpayer  identification  number may be subject to  penalties
imposed by the IRS.  In  addition,  the  Company  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 the Company.  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.

         The Company will report to its Non-U.S. Shareholders and to the IRS the
amount  of  dividends  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 Shares to
Non-U.S.  Shareholders,  and the New  Regulations  will when effective alter the
information reporting and withholding rules applicable to Non-U.S. Shareholders.
Among other things, the New Regulations provide certain presumptions under which
a Non-U.S.  Shareholder  would be subject to backup  withholding and information
reporting until the Company receives  certification from such shareholder of its
Non-U.S.  Shareholder  status.  As  noted,  the New  Regulations  are  generally
effective with respect to dividends paid after December 31, 1998.

         The  payment  of the  proceeds  from the  disposition  of  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 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 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 (i) a
"controlled  foreign  corporation"  for  federal  income tax  purposes or (ii) 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 New Regulations  (generally  effective for
payments  made  after  December  31,  1998),  in the  case  of  proceeds  from a
disposition  of 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 (i) a "controlled foreign  corporation" for federal income
tax  purposes,  (ii) 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, (iii) 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 (iv) 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-

                                       17
<PAGE>
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.

         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.  Holders of Shares should recognize that the
present  federal  income tax  treatment of the Company may be modified by future
legislative,  judicial,  or  administrative  actions  at any time,  which may be
retroactive in effect,  and, as a result, any such action or decision may affect
investments  and  commitments  previously  made.  The rules dealing with federal
income  taxation  are  constantly  under  review  by  persons  involved  in  the
legislative  process and by the IRS and the  Treasury  Department,  resulting in
statutory  changes as well as  promulgation  of new  regulations,  revisions  to
existing  regulations,  and revised  interpretations of established concepts. No
prediction  can  be  made  as to the  likelihood  of  passage  of  any  new  tax
legislation  or other  provisions  either  directly or indirectly  affecting the
Company  or  its  shareholders.   Revisions  in  federal  income  tax  laws  and
interpretations   thereof  could  adversely   affect  the  tax  consequences  of
investment in the Shares.

         The Company and its  shareholders may also be subject to state or local
taxation in various state or local jurisdictions, including those in which it or
they  transact  business  or reside.  The state and local tax  treatment  of the
Company  and  its  shareholders  may  not  conform  to the  federal  income  tax
consequences discussed above. Consequently, holders should consult their own tax
advisors  regarding  the effect of state and local tax laws on an  investment in
the Shares.

         THE  FOREGOING IS A SUMMARY  DESCRIPTION  OF CERTAIN  MATERIAL  FEDERAL
INCOME TAX  CONSEQUENCES  OF THE  TAXATION OF THE COMPANY AND ITS  SHAREHOLDERS,
WITHOUT   CONSIDERATION  OF  THE  PARTICULAR  FACTS  AND  CIRCUMSTANCES  OF  ANY
PARTICULAR SHAREHOLDER.  IN PARTICULAR,  IT DOES NOT ADDRESS THE STATE, LOCAL OR
FOREIGN TAX ASPECTS OF THE  TAXATION  OF THE COMPANY AND ITS  SHAREHOLDERS.  THE
DISCUSSION IS BASED ON CURRENTLY EXISTING  PROVISIONS OF THE CODE,  EXISTING AND
PROPOSED TREASURY REGULATIONS  THEREUNDER AND CURRENT ADMINISTRATIVE RULINGS AND
COURT DECISIONS.  ALL OF THE FOREGOING ARE SUBJECT TO CHANGE AND ANY SUCH CHANGE
COULD  AFFECT THE  CONTINUING  VALIDITY OF THE  DISCUSSION.  THE COMPANY AND ITS
SHAREHOLDERS  MAY ALSO BE SUBJECT TO STATE OR LOCAL TAXATION IN VARIOUS STATE OR
LOCAL  JURISDICTIONS,  INCLUDING THOSE IN WHICH IT OR THEY TRANSACT  BUSINESS OR
RESIDE.  EACH HOLDER OF SHARES OF THE COMPANY  SHOULD CONSULT HIS OR HER OWN TAX
ADVISOR AS TO THE SPECIFIC TAX  CONSEQUENCES  OF THE TAXATION OF THE COMPANY AND
ITS SHAREHOLDERS,  INCLUDING THE APPLICATION AND EFFECT OF FEDERAL, STATE, LOCAL
AND FOREIGN TAX LAWS.

           ERISA PLANS, KEOGH PLANS AND INDIVIDUAL RETIREMENT ACCOUNTS

         General Fiduciary Obligations. Fiduciaries of a pension, profit-sharing
or other  employee  benefit plan  subject to Title I of the Employee  Retirement
Income Security Act of 1974 ("ERISA") ("ERISA Plan") must consider whether their
investment in the Company's Shares satisfies the diversification requirements of
ERISA, whether the investment is prudent in light of possible limitations on the
marketability of the Shares,  whether such fiduciaries have authority to acquire
such Shares under the appropriate governing instrument and Title I of ERISA, and
whether  such   investment  is  otherwise   consistent   with  their   fiduciary
responsibilities.   Any  ERISA  Plan  fiduciary  should  also  consider  ERISA's
prohibition on improper  delegation of control over or responsibility  for "plan
assets."  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,  such fiduciaries may be subject to a
civil  penalty  of up to 20% of any amount  recovered  by the plan on account of
such 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  because  it does not cover  common  law  employees
("Non-ERISA  Plan") should  consider that such 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 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 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 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).  The 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.

         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 the 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 the 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.  The  Company  believes  that the  restrictions  imposed  under the
Declaration on the transfer of Shares do not result in the failure of the Shares
to be "freely transferable."  Furthermore,  the Company believes that at present
there exist no other facts or circumstances  limiting the transferability of the
Shares which are not included among those enumerated as not affecting their free
transferability under the regulation,  and the Company does not expect or intend
to impose in the future (or to permit  any person to impose on its  behalf)  any
limitations or restrictions on  transferwhich  would not be among the enumerated
permissible  limitations or  restrictions.  However,  the final  regulation only
establishes a presumption in favor of a finding of free transferability,  and no
guarantee can be given that the DOL or the Treasury  Department will not reach a
contrary conclusion.

                                       19

         Assuming  that the Shares will be "widely held" and that no other facts
and  circumstances  exist which  restrict  transferability  of the  Shares,  the
Company has received an opinion of counsel that the Shares should not fail to be
"freely  transferable" for purposes of the regulation due to the restrictions on
transfer of the Shares under the  Declaration  and that under the regulation the
Shares are publicly offered securities and the assets of the Company will not be
deemed to be "plan assets" of any ERISA Plan,  IRA or other  Non-ERISA Plan that
invests in the Shares.

         If the assets of the Company are deemed to be plan assets  under ERISA,
(i) the prudence  standards  and other  provisions of Part 4 of Title I of ERISA
would be  applicable  to  investments  made by the  Company;  (ii) the person or
persons having investment discretion over the assets of ERISA Plans which invest
in the Company  would be liable  under the  aforementioned  Part 4 of Title I of
ERISA for  investments  made by the  Company  which do not conform to such ERISA
standards  unless the  Advisor  registers  as an  investment  adviser  under the
Investment Advisers Act of 1940 and certain other conditions are satisfied;  and
(iii)  certain  transactions  that the Company  might enter into in the ordinary
course of its business and operation might constitute "prohibited  transactions"
under ERISA and the Code.

Item 2.  Properties

         General. At December 31, 1997, approximately 14% of the Company's total
investments  were in long-term  care  facilities,  32% were in medical and other
office buildings and clinics, 20% were in government office buildings,  21% were
in retirement  and assisted  living  communities,  8% were in nursing homes with
subacute  services and 5% were in hotels through the Company's equity investment
in HPT. The Company  believes that the physical  plant of each of the facilities
in which it has  invested  is  suitable  and  adequate  for its  present and any
currently  proposed  uses.  At December  31,  1997,  the Company had real estate
investments  totaling $2.1 billion (at cost) in 217 properties  that were leased
to or operated by over  approximately  350 tenants or  mortgagors,  plus a 10.3%
investment of approximately  $111.1 million  (carrying value) through HPT in 119
additional properties.

Item 3.  Legal Proceedings

         As previously disclosed,  in early 1995 the Company commenced an action
in Florida state court to collect on a secured indemnity agreement from a former
tenant and mortgagor, together with certain related parties (collectively,
the "Former  Tenant").  In May 1995 the Former Tenant filed a  counterclaim  and
third-party  complaint against the Company and others including  Messrs.  Martin
and Portnoy,  Advisor and Sullivan & Worcester LLP, seeking, among other things,
to set aside the indemnity agreement and to recover substantial damages. After a
Massachusetts state court ordered the dispute to arbitration and a Florida court
stayed  further  proceedings  pending  arbitration,  the Former Tenant brought a
separate   action  against  the  Company  in  the  Federal   District  Court  in
Massachusetts   and  realleged  many  of  the  same   allegations  made  in  the
counterclaims and third-party  complaints 

                                       22
<PAGE>
previously  brought by them in response to the Company's  original  action,  and
adding  allegations  of violations of Sections 10(b) and 20(a) of the Securities
Exchange Act of 1934 and Rule 10b-5 promulgated  thereunder and violations of 18
U.S.C ss. 1962 (RICO).  In September  1996,  the Federal Court in  Massachusetts
ordered the case brought by the Former Tenant dismissed and all disputes between
the Former Tenant and the Company  referred to  arbitration.  The arbitration is
proceeding. The amounts of damages claimed by the Former Tenant and creditors or
assignees  of the former  Tenant are  material.  The  Company  is  pursuing  its
indemnity  claims  against the Former  Tenant and is defending the claims of the
Former  Tenant in the  arbitration  proceedings.  The Company  intends to defend
itself in  related  actions  brought  and which may be  brought,  to  attempt to
consolidate  these cases in the pending  arbitration  proceeding or otherwise to
pursue such claims and rights  which it may have.  The outcome of these  pending
claims and proceedings cannot be predicted.

         The  Declaration of Trust provides that Trustees,  officers,  employees
and agents of the  Company  shall be  indemnified  by the  Company  against  any
losses, judgments,  liabilities,  expenses and amounts paid in settlement of any
claims  asserted  against  them by reason of their  status,  provided  that such
claims were not the result of willful  misfeasance,  bad faith, gross negligence
or reckless disregard of duty. Were Messrs. Martin and Portnoy to be held liable
in the  proceedings  described  above,  they  may  therefore  have a  claim  for
indemnification from the Company.

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

         performance of an equity REIT that provides a relevant basis for comparison  among REITs.  FFO does not represent cash flow
         from operating  activities  (as  determined in accordance  with GAAP) and should not be considered as an alternative to net

direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of Securities of such series may, alternatively, be
embodied in and  evidenced by the record of Holders of Securities of such series
voting  in favor  thereof,  either in person or by  proxies  duly  appointed  in
writing,  at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article  Fifteen,  or a combination of
such  instruments  and any such  record.  Except as herein  otherwise  expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required,  to the Company.  Such  instrument or instruments  and any such record
(and the action  embodied  therein and evidenced  thereby) are herein  sometimes
referred to as the "Act" of the Holders  signing such  instrument or instruments
or so voting at any such meeting.  Proof of execution of any such  instrument or
of a writing  appointing  any such  agent,  or of the holding by any Person of a
Security,  shall be sufficient  for any purpose of this Indenture and conclusive
in favor of the  Trustee  and the  Company  and any agent of the  Trustee or the
Company,  if made in the  manner  provided  in this  Section.  The record of any
meeting of  Holders of  Securities  shall be proved in the  manner  provided  in
Section 1506.

                  (b) The fact and date of the  execution  by any  Person of any
such  instrument  or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer  authorized by
law to take  acknowledgments  of deeds,  certifying that the individual  signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution  is by a  signer  acting  in a  capacity  other  than  his  individual
capacity,  such certificate or affidavit shall also constitute  sufficient proof
of his authority.  The fact and date of the execution of any such  instrument or
writing,  or the authority of the Person  executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

                  (c) The ownership of Registered  Securities shall be proved by
the Security Register.

                  (d) The  ownership of Bearer  Securities  may be proved by the
production  of  such  Bearer  Securities  or  by  a  certificate   executed,  as
depositary,  by any trust company,  bank, banker or other  depositary,  wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory,
showing that at the date therein mentioned

                                        8
<PAGE>
such Person had on deposit with such depositary,  or exhibited to it, the Bearer
Securities therein described;  or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer  Securities,  if such certificate or
affidavit  is deemed by the  Trustee to be  satisfactory.  The  Trustee  and the
Company may assume that such ownership of any Bearer  Security  continues  until
(1) another  certificate or affidavit  bearing a later date issued in respect of
the same Bearer Security is produced, or (2) such Bearer Security is produced to
the Trustee by some other Person,  or (3) such Bearer Security is surrendered in
exchange for a  Registered  Security,  or (4) such Bearer  Security is no longer
Outstanding.  The ownership of Bearer Securities may also be proved in any other
manner which the Trustee deems sufficient.

                  (e)  If  the  Company   shall  solicit  from  the  Holders  of
Registered Securities any request,  demand,  authorization,  direction,  notice,
consent,  waiver or other Act, the Company may, at its option, in or pursuant to
a Board  Resolution,  fix in  advance  a record  date for the  determination  of
Holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding  TIA Section  316(c),  such record date shall be the record date
specified  in or  pursuant to such Board  Resolution,  which shall be a date not
earlier  than  the date 30 days  prior  to the  first  solicitation  of  Holders
generally in connection  therewith and not later than the date such solicitation
is  completed.   If  such  a  record  date  is  fixed,  such  request,   demand,
authorization,  direction,  notice,  consent,  waiver  or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such  record date shall be deemed to be Holders for the  purposes of
determining   whether  Holders  of  the  requisite   proportion  of  Outstanding
Securities  have  authorized  or agreed or  consented to such  request,  demand,
authorization,  direction,  notice,  consent,  waiver or other Act, and for that
purpose the  Outstanding  Securities  shall be computed as of such record  date;
provided that no such authorization, agreement or consent by the Holders on such
record date shall be deemed effective unless it shall become effective  pursuant
to the  provisions  of this  Indenture  not later than eleven  months  after the
record date.

                  (f) Any request,  demand,  authorization,  direction,  notice,
consent,  waiver or other Act of the  Holder of any  Security  shall  bind every
future Holder of the same Security and the Holder of every Security  issued upon
the registration of transfer thereof or in exchange  therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee,  any
Security Registrar, any Paying Agent, any Authenticating Agent or the Company in
reliance  thereon,  whether  or not  notation  of such  action is made upon such
Security.

                  SECTION  105.  Notices,  etc.,  to Trustee  and  Company.  Any
request,  demand,  authorization,  direction,  notice, consent, waiver or Act of
Holders or other  document  provided or permitted  by this  Indenture to be made
upon, given or furnished to, or filed with,

                  (1) the  Trustee  by any  Holder  or by the  Company  shall be
         sufficient  for every purpose  hereunder if made,  given,  furnished or
         filed in writing to or with the Trustee at its Corporate  Trust Office,
         Attention:   Corporate  Trust  Department  Re:  Health  and  Retirement
         Properties Trust Notes due 2007, or

                  (2) the  Company  by the  Trustee  or by any  Holder  shall be
         sufficient  for  every  purpose   hereunder  (unless  otherwise  herein
         expressly  provided)  if in writing  and mailed,  first  class  postage
         prepaid, to the Company addressed to it at the address of its principal
         office  specified in the first  paragraph  of this  Indenture or at any
         other  address  previously  furnished  in writing to the Trustee by the
         Company.

                  SECTION 106. Notice to Holders;  Waiver.  Where this Indenture
provides  for  notice of any event to Holders of  Registered  Securities  by the
Company  or the  Trustee,  such  notice  shall  be  sufficiently  given  (unless
otherwise  herein  expressly  provided)  if in writing and  mailed,  first-class
postage  prepaid,  to each such Holder affected by such event, at his address as
it appears in the Security  Register,  not later than the latest  date,  and not
earlier than the earliest date, prescribed for the giving of such notice. In any
case where notice to Holders of Registered  Securities is given by mail, neither
the failure to mail such notice,  nor any defect in any notice so mailed, to any
particular  Holder shall affect the  sufficiency  of such notice with respect to
other  Holders of  Registered  Securities  or the  sufficiency  of any notice to
Holders of Bearer  Securities given as provided  herein.  Any notice mailed to a
Registered Holder in the manner herein  prescribed shall be conclusively  deemed
to have been  received  by such  Holder,  whether  or not such  Holder  actually
receives such notice.

                                        9
<PAGE>
                  If by reason of the suspension of or irregularities in regular
mail service or by reason of any other cause it shall be  impracticable  to give
such notice by mail, then such notification to Holders of Registered  Securities
as shall be made with the approval of the Trustee shall  constitute a sufficient
notification to such Holders for every purpose hereunder.

                  Except as  otherwise  expressly  provided  herein or otherwise
specified  with respect to any  Securities  pursuant to Section 301,  where this
Indenture provides for notice to Holders of Bearer Securities of any event, such
notice shall be  sufficiently  given if published in an Authorized  Newspaper in
The City of New York and in such  other  city or cities as may be  specified  in
such  Securities on a Business Day,  such  publication  to be not later than the
latest date, and not earlier than the earliest  date,  prescribed for the giving
of such  notice.  Any such notice shall be deemed to have been given on the date
of such  publication  or, if published  more than once, on the date of the first
such publication.

                  If  by  reason  of  the   suspension  of  publication  of  any
Authorized Newspaper or Authorized Newspapers or by reason of any other cause it
shall be impracticable to publish any notice to Holders of Bearer  Securities as
provided above,  then such notification to Holders of Bearer Securities as shall
be given with the approval of the Trustee shall constitute  sufficient notice to
such Holders for every purpose hereunder.  Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so  published,  shall  affect the  sufficiency  of such
notice with respect to other Holders of Bearer  Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

                  Any request, demand, authorization, direction, notice, consent
or waiver  required or permitted  under this  Indenture  shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

                  Where this Indenture  provides for notice in any manner,  such
notice may be waived in writing by the Person  entitled to receive  such notice,
either  before or after the event,  and such waiver shall be the  equivalent  of
such notice.  Waivers of notice by Holders shall be filed with the Trustee,  but
such filing  shall not be a condition  precedent  to the  validity of any action
taken in reliance upon such waiver.

                  SECTION 107.  Effect of Headings  and Table of  Contents.  The
Article  and  Section  headings  herein  and  the  Table  of  Contents  are  for
convenience only and shall not affect the construction hereof.

                  SECTION  108.  Successors  and  Assigns.   All  covenants  and
agreements  in this  Indenture  by the  Company  shall bind its  successors  and
assigns, whether so expressed or not.

                  SECTION 109.  Separability  Clause.  In case any  provision in
this  Indenture  or in any  Security  or coupon  shall be  invalid,  illegal  or
unenforceable,  the  validity,  legality  and  enforceability  of the  remaining
provisions shall not in any way be affected or impaired thereby.

                  SECTION 110. Benefits of Indenture.  Nothing in this Indenture
or in the Securities or coupons,  express or implied,  shall give to any Person,
other than the parties hereto,  any Security  Registrar,  any Paying Agent,  any
Authenticating  Agent and their successors hereunder and the Holders any benefit
or any legal or equitable right, remedy or claim under this Indenture.

                  SECTION 111.  Governing Law. This Indenture and the Securities
and coupons shall be governed by and construed in accordance with the law of The
Commonwealth  of  Massachusetts.  This Indenture is subject to the provisions of
the TIA that are required to be part of this Indenture and shall,  to the extent
applicable, be governed by such provisions.

                  SECTION 112.  Legal  Holidays.  In any case where any Interest
Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated
Maturity or Maturity of any Security shall not be a Business Day at any Place of
Payment,  then  (notwithstanding  any other  provision of this  Indenture or any
Security or coupon other than a provision in the  Securities of any series which
specifically states that such provision shall apply in lieu hereof),

                                       10

payment of interest or any Additional Amounts or principal (and premium, if any)
or sinking  fund payment need not be made at such Place of Payment on such date,
but may be made on the next  succeeding  Business  Day at such  Place of Payment
with  the  same  force  and  effect  as if made on the  Interest  Payment  Date,
Redemption  Date,  Repayment Date or sinking fund payment date, or at the Stated
Maturity or Maturity;  provided  that no interest  shall accrue on the amount so
payable for the period from and after such  Interest  Payment  Date,  Redemption
Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity, as
the case may be.

                  SECTION 113. No Personal  Liability.  THE AMENDED AND RESTATED
DECLARATION  OF  TRUST OF THE  COMPANY  DATED  JULY 1,  1994,  A COPY OF  WHICH,
TOGETHER WITH ALL AMENDMENTS THERETO (THE  "DECLARATION"),  IS DULY FILED IN THE
OFFICE OF THE DEPARTMENT OF  ASSESSMENTS  AND TAXATION OF THE STATE OF MARYLAND,
PROVIDES THAT THE NAME "HEALTH AND  RETIREMENT  PROPERTIES  TRUST" REFERS TO THE
TRUSTEES UNDER THE DECLARATION COLLECTIVELY AS TRUSTEES, BUT NOT INDIVIDUALLY OR
PERSONALLY, AND THAT NO TRUSTEE, OFFICER, SHAREHOLDER,  EMPLOYEE OR AGENT OF THE
COMPANY SHALL BE HELD TO ANY PERSONAL LIABILITY,  JOINTLY OR SEVERALLY,  FOR ANY
OBLIGATION  OF, OR CLAIM  AGAINST,  THE  COMPANY.  ALL PERSONS  DEALING WITH THE
COMPANY,  IN ANY WAY,  SHALL  LOOK  ONLY TO THE  ASSETS OF THE  COMPANY  FOR THE
PAYMENT OF ANY SUM OR THE PERFORMANCE OF ANY OBLIGATION.

                                   ARTICLE TWO

                                SECURITIES FORMS

related coupons shall be in  substantially  the forms as shall be established in
one or more indentures  supplemental  hereto or approved from time to time by or
pursuant to a Board  Resolution in accordance  with Section 301, shall have such

                  SECTION 203. Securities Issuable in Global Form. If Securities
of or within a series  are  issuable  in global  form,  as  specified  in and as
contemplated by Section 301, then, notwithstanding clause (8) of Section 301 and
the  provisions of Section 302, any such Security  shall  represent  such of the
Outstanding  Securities  of such  series as shall be  specified  therein and may
provide that it shall represent the aggregate  amount of Outstanding  Securities
of such series from time to time endorsed  thereon and that the aggregate amount
of Outstanding  Securities of such series  represented  thereby may from time to
time be  increased  or  decreased to reflect  exchanges.  Any  endorsement  of a
Security in global form to reflect  the amount,  or any  increase or decrease in
the amount, of Outstanding  Securities  represented thereby shall be made by the
Trustee in such manner and upon instructions  given by such Person or Persons as

Security in permanent global form in the manner and upon  instructions  given by
the Person or Persons specified therein or in the applicable Company Order. If a
Company  Order  pursuant to Section 303 or 304 has been, or  simultaneously  is,
delivered,  any  instructions  by the Company  with  respect to  endorsement  or
delivery or redelivery of a Security in global form shall be in writing but need
not  comply  with  Section  102 and need not be  accompanied  by an  Opinion  of
Counsel.

                  The provisions of the last sentence of Section 303 shall apply
to any Security  represented  by a Security in global form if such  Security was
never issued and sold by the Company and the Company delivers to the Trustee the
Security in global  form  together  with  written  instructions  (which need not
comply with  Section 102 and need not be  accompanied  by an Opinion of Counsel)
with regard to the reduction in the principal  amount of Securities  represented
thereby,  together with the written statement  contemplated by the last sentence
of Section 303.

                  Notwithstanding   the   provisions  of  Section  307,   unless
otherwise  specified as contemplated by Section 301, payment of principal of and
any premium and interest on any Security in permanent  global form shall be made
to the Person or Persons specified therein.

                  Notwithstanding  the  provisions  of Section 308 and except as
provided in the preceding  paragraph,  the Company, the Trustee and any agent of
the Company and the Trustee shall treat as the Holder of such  principal  amount
of Outstanding  Securities represented by a permanent global Security (i) in the

         Indenture with respect to Securities of the series (whether or not such
         Events of  Default  or  covenants  are  consistent  with the  Events of
         Default or covenants set forth herein);

                  (15)  whether  Securities  of the series are to be issuable as
         Registered  Securities,  Bearer Securities (with or without coupons) or
         both,  any  restrictions  applicable to the offer,  sale or delivery of
         Bearer  Securities  and the terms upon which Bearer  Securities  of the
         series may be exchanged  for  Registered  Securities  of the series and
         vice versa (if permitted by applicable laws and  regulations),  whether
         any Securities of the series are to be issuable  initially in temporary
         global form and whether any Securities of the series are to be issuable
         in permanent  global form with or without  coupons and, if so,  whether
         beneficial  owners of interests in any such permanent  global  Security
         may exchange such  interests for  Securities of such series and of like
         tenor of any authorized  form and  denomination  and the  circumstances
         under which any such  exchanges may occur,  if other than in the manner

         issuance of the first Security of the series to be issued;

                  (17)  the  Person  to  whom  any  interest  on any  Registered
         Security of the series  shall be  payable,  if other than the Person in
         whose name that  Security (or one or more  Predecessor  Securities)  is
         registered at the close of business on the Regular Record Date for such
         interest,  the manner in which,  or the Person to whom, any interest on

         any  interest  payable on a  temporary  global  Security on an Interest

         to the Securities of the series and any provisions in modification  of,
         in addition to or in lieu of any of the provisions of Article Fourteen;

                  (19) if the  Securities  of such  series are to be issuable in
         definitive  form  (whether  upon  original  issue or upon exchange of a

         certificates or other  documents or  satisfaction of other  conditions,

         exercise of warrants, the time, manner and place for such Securities to
         be authenticated and delivered;

                  (21) whether and under what circumstances the Company will pay
         Additional Amounts as contemplated by Section 1007 on the Securities of
         the series to any Holder who is not a United States  person  (including
         any modification to the definition of such term) in respect of any tax,
         assessment or governmental  charge and, if so, whether the Company will
         have  the  option  to  redeem  such  Securities  rather  than  pay such
         Additional Amounts (and the terms of any such option);

                  (22) the  obligation,  if any,  of the  Company  to permit the

         be, and the terms and conditions  upon which such  conversion  shall be
         effected (including, without limitation, the

                                       14
<PAGE>
         initial conversion price or rate, the conversion period, any adjustment

         reservation of such shares for purposes of conversion);

                  (23) the terms and  conditions,  if any, upon which payment of
         the Securities of such series shall be  subordinated  to the Securities
         of another  series or other  indebtedness  of the  Company  (including,
         without limitation, indebtedness which ranks senior to such Securities;
         restrictions on payments to Holders of such Securities  while a default
         with respect to such senior  indebtedness is continuing;  restrictions,
         if any,  on payments to the  Holders of such  Securities  following  an
         Event of Default;  and any  requirements for Holders of such Securities
         to remit certain payments to the holders of such senior indebtedness);

                  (24) if the Securities of the series are to be guaranteed, the
         term and conditions of such guarantee;

                  (25) if other than the Trustee,  the identity of each Security
         Registrar and/or Paying Agent for the series; and

                  (26) any other terms of the series  (which  terms shall not be
         inconsistent with the provisions of this Indenture).

                  All Securities of any one series and the coupons  appertaining
to any Bearer Securities of such series shall be substantially identical except,
in the case of  Registered  Securities,  as to  denominations  and except as may
otherwise be provided in or pursuant to the Board  Resolution  establishing  the
series (subject to Section 303) and set forth in an Officers'  Certificate or in
any indenture  supplemental hereto. All Securities of any one series need not be
issued  at the same  time  and,  unless  otherwise  provided,  a  series  may be
reopened,  without the  consent of the  Holders,  for  issuances  of  additional
Securities of such series.

                  If any of  the  terms  of the  Securities  of any  series  are
established by action taken pursuant to one or more Board Resolutions, a copy of
an appropriate  record of such action(s)  shall be certified by the Secretary or
an Assistant  Secretary of the Company and  delivered to the Trustee at or prior
to the  delivery of the  Officers'  Certificate  setting  forth the terms of the
Securities of such series.

                  SECTION  302.  Denominations.  The  Securities  of each series
shall be issuable in such denominations as shall be specified as contemplated by
Section 301. With respect to Securities of any series denominated in Dollars, in
the absence of any such  provisions,  the Registered  Securities of such series,
other than  Registered  Securities  issued in global  form  (which may be of any
denomination),  shall be issuable in  denominations  of $1,000 and any  integral
multiple thereof.

                  SECTION 303. Execution,  Authentication,  Delivery and Dating.
The Securities and any coupons  appertaining thereto shall be executed on behalf
of the Company by its  President or one of its Vice  Presidents,  under its seal
reproduced  thereon,  and  attested  by its  Secretary  or one of its  Assistant
Secretaries.  The  signature  of any of these  officers  on the  Securities  and
coupons may be manual or facsimile  signatures of the present or any future such
authorized  officer  and  may  be  imprinted  or  otherwise  reproduced  on  the
Securities.

                  Securities   or  coupons   bearing  the  manual  or  facsimile
signatures  of  individuals  who  were at any time the  proper  officers  of the
Company shall bind the Company,  notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the  authentication  and delivery
of such  Securities or did not hold such offices at the date of such  Securities
or coupons.

                  At any time and from  time to time  after  the  execution  and
delivery of this  Indenture,  the Company may deliver  Securities of any series,
together with any coupon  appertaining  thereto,  executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities,  and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities;  provided,  however, that,
in connection with its original issuance,  no Bearer Security shall be mailed or
otherwise delivered to any location in the

                                       15
<PAGE>

United  States;  and provided  further that,  unless  otherwise  specified  with
respect to any series of Securities  pursuant to Section 301, a Bearer  Security
may be delivered in  connection  with its original  issuance  only if the Person
entitled to receive such Bearer  Security  shall have furnished a certificate in
the form set forth in Exhibit A-1 to this Indenture or such other certificate as
may be specified  with respect to any series of  Securities  pursuant to Section
301,  dated no earlier  than 15 days  prior to the  earlier of the date on which
such Bearer  Security is delivered and the date on which any temporary  Security
first becomes exchangeable for such Bearer Security in accordance with the terms
of such  temporary  Security  and  this  Indenture.  If any  Security  shall  be
represented by a permanent  global Bearer  Security,  then, for purposes of this
Section and Section 304, the notation of a beneficial  owner's  interest therein
upon  original  issuance  of such  Security  or upon  exchange of a portion of a
temporary  global Security shall be deemed to be delivery in connection with its
original  issuance of such beneficial  owner's interest in such permanent global
Security. Except as permitted by Section 306, the Trustee shall not authenticate
and deliver any Bearer Security unless all appurtenant coupons for interest then
matured have been detached and  cancelled.  If all the  Securities of any series
are not to be  issued at one time and if the Board  Resolution  or  supplemental
indenture  establishing such series shall so permit,  such Company Order may set
forth  procedures  acceptable to the Trustee for the issuance of such Securities
and  determining  the terms of  particular  Securities  of such series,  such as
interest rate or formula,  maturity  date,  date of issuance and date from which
interest shall accrue.  In  authenticating  such  Securities,  and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee  shall be entitled to receive,  and (subject to TIA Sections  315(a)
through 315(d)) shall be fully protected in relying upon,

                  (i) an Opinion of Counsel stating that

                                    (a) the form or forms of such Securities and
                  any  coupons  have been  established  in  conformity  with the
                  provisions of this Indenture;

                                    (b) the  terms  of such  Securities  and any
                  coupons  have  been   established   in  conformity   with  the
                  provisions of this Indenture; and

                                    (c)  such  Securities,   together  with  any
                  coupons  appertaining  thereto,  when completed by appropriate
                  insertions  and executed  and  delivered by the Company to the
                  Trustee for  authentication in accordance with this Indenture,
                  authenticated  and delivered by the Trustee in accordance with
                  this  Indenture  and  issued by the  Company in the manner and
                  subject  to  any  conditions  specified  in  such  Opinion  of
                  Counsel,  will constitute legal, valid and binding obligations
                  of the Company,  enforceable  in accordance  with their terms,
                  subject to applicable bankruptcy,  insolvency,  reorganization
                  and other similar laws of general applicability relating to or
                  affecting the enforcement of creditors'  rights  generally and
                  to general equitable principles; and

                  (ii) an  Officers'  Certificate  stating  that all  conditions
         precedent  provided for in this  Indenture  relating to the issuance of
         the  Securities  have been  complied  with and that, to the best of the
         knowledge of the signers of such certificate,  no Event of Default with
         respect to any of the Securities shall have occurred and be continuing.

If such  form or terms  have  been so  established,  the  Trustee  shall  not be
required  to  authenticate  such  Securities  if the  issue  of such  Securities
pursuant  to this  Indenture  will  affect the  Trustee's  own  rights,  duties,
obligations  or immunities  under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

                  Notwithstanding  the  provisions  of  Section  301  and of the
preceding paragraph, if all the Securities of any series are not to be issued at
one  time,  it shall  not be  necessary  to  deliver  an  Officers'  Certificate
otherwise  required pursuant to Section 301 or a Company Order, or an Opinion of
Counsel or an Officers' Certificate otherwise required pursuant to the preceding
paragraph  at the time of issuance of each  Security  of such  series,  but such
order,  opinion and certificates,  with appropriate  modifications to cover such
future  issuances,  shall be  delivered at or before the time of issuance of the
first Security of such series.

                                       16
<PAGE>
                  Each  Registered  Security  shall  be  dated  the  date of its
authentication  and each Bearer Security shall be dated as of the date specified
as contemplated by Section 301.

                  No Security or coupon  shall be entitled to any benefit  under
this Indenture or be valid or obligatory for any purpose unless there appears on
such  Security  or Security to which such coupon  appertains  a  certificate  of
authentication  substantially  in the form  provided for herein duly executed by
the Trustee by manual signature of an authorized  officer,  and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered  hereunder and is entitled to
the benefits of this Indenture.  Notwithstanding the foregoing,  if any Security
shall have been authenticated and delivered  hereunder but never issued and sold
by the Company,  and the Company  shall deliver such Security to the Trustee for
cancellation as provided in Section 309 together with a written statement (which
need not comply with  Section 102 and need not be  accompanied  by an Opinion of
Counsel)  stating  that such  Security  has never  been  issued  and sold by the
Company,  for all purposes of this Indenture such Security shall be deemed never
to have been  authenticated and delivered  hereunder and shall never be entitled
to the benefits of this Indenture.

                  SECTION 304. Temporary Securities. (a) Pending the preparation
of  definitive  Securities  of any series,  the Company  may  execute,  and upon
Company Order the Trustee shall authenticate and deliver,  temporary  Securities
which  are  printed,  lithographed,   typewritten,   mimeographed  or  otherwise
produced,  in any  authorized  denomination,  substantially  of the tenor of the
definitive  Securities in lieu of which they are issued, in registered form, or,
if authorized,  in bearer form with one or more coupons or without coupons,  and
with such appropriate insertions, omissions,  substitutions and other variations
as the  officers  executing  such  Securities  may  determine,  as  conclusively
evidenced by their  execution of such  Securities.  In the case of Securities of
any series, such temporary Securities may be in global form.

                  Except in the case of  temporary  Securities  in  global  form
(which  shall be  exchanged in  accordance  with Section  304(b) or as otherwise
provided in or pursuant to a Board Resolution),  if temporary  Securities of any
series are issued,  the Company will cause definitive  Securities of that series
to be prepared without  unreasonable  delay. After the preparation of definitive
Securities  of such series,  the  temporary  Securities  of such series shall be
exchangeable  for  definitive  Securities  of such series upon  surrender of the
temporary  Securities of such series at the office or agency of the Company in a
Place of Payment for that series,  without charge to the Holder.  Upon surrender
for  cancellation  of any  one  or  more  temporary  Securities  of  any  series
(accompanied by any non-matured coupons appertaining thereto), the Company shall
execute and the Trustee shall  authenticate  and deliver in exchange  therefor a
like principal amount of definitive  Securities of the same series of authorized
denominations;  provided,  however,  that no definitive Bearer Security shall be
delivered in exchange for a temporary Registered Security;  and provided further
that a definitive Bearer Security shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in Section 303.
Until so exchanged, the temporary Securities of any series shall in all respects
be entitled to the same benefits under this  Indenture as definitive  Securities
of such series.

                  (b)  Unless  otherwise  provided  in or  pursuant  to a  Board
Resolution,   this  Section  304(b)  shall  govern  the  exchange  of  temporary
Securities  issued in global form other than through the  facilities  of DTC. If
any such temporary Security is issued in global form, then such temporary global
Security shall,  unless otherwise  provided therein,  be delivered to the London
office of a depositary or common depositary (the "Common  Depositary"),  for the
benefit of Euroclear  and CEDEL,  for credit to the  respective  accounts of the
beneficial  owners of such  Securities  (or to such other  accounts  as they may
direct).

                  Without  unnecessary delay but in any event not later than the
date  specified in, or determined  pursuant to the terms of, any such  temporary
global Security (the "Exchange Date"),  the Company shall deliver to the Trustee
definitive  Securities,  in aggregate  principal  amount equal to the  principal
amount of such temporary global Security,  executed by the Company.  On or after
the Exchange Date,  such temporary  global  Security shall be surrendered by the
Common Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged,  in whole or from  time to time in part,  for  definitive  Securities
without charge, and the Trustee shall authenticate and deliver,  in exchange for
each portion of such temporary  global  Security,  an equal aggregate  principal
amount of definitive  Securities of the same series of authorized  denominations
and of like  tenor  as the  portion  of such  temporary  global  Security  to be
exchanged.

                                       17
<PAGE>

The  definitive  Securities  to be delivered in exchange for any such  temporary
global  Security  shall be in bearer form,  registered  form,  permanent  global
bearer form or permanent global registered form, or any combination  thereof, as
specified as contemplated by Section 301, and, if any combination  thereof is so
specified,  as requested by the  beneficial  owner thereof;  provided,  however,
that,  unless otherwise  specified in such temporary global Security,  upon such
presentation  by the  Common  Depositary,  such  temporary  global  Security  is
accompanied  by a certificate  dated the Exchange Date or a subsequent  date and
signed by Euroclear as to the portion of such temporary global Security held for
its account then to be exchanged and a certificate  dated the Exchange Date or a
subsequent  date and signed by CEDEL as to the portion of such temporary  global
Security held for its account then to be  exchanged,  each in the form set forth
in Exhibit  A-2 to this  Indenture  or in such other form as may be  established
pursuant to Section 301; and provided further that definitive  Bearer Securities
shall be delivered in exchange for a portion of a temporary global Security only
in compliance with the requirements of Section 303.

                  Unless otherwise  specified in such temporary global Security,
the  interest of a  beneficial  owner of  Securities  of a series in a temporary
global Security shall be exchanged for definitive  Securities of the same series
and of like tenor following the Exchange Date when the account holder  instructs
Euroclear or CEDEL,  as the case may be, to request such  exchange on his behalf
and  delivers to Euroclear or CEDEL,  as the case may be, a  certificate  in the
form set forth in Exhibit A-1 to this  Indenture  (or in such other forms as may
be established  pursuant to Section 301), dated no earlier than 15 days prior to
the Exchange  Date,  copies of which  certificate  shall be  available  from the
offices of Euroclear and CEDEL, the Trustee,  any Authenticating Agent appointed
for such series of Securities and each Paying Agent.  Unless otherwise specified
in such  temporary  global  Security,  any such  exchange  shall be made free of
charge to the beneficial owners of such temporary global Security, except that a
Person receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL. Definitive Securities
in bearer form to be delivered in exchange for any portion of a temporary global
Security shall be delivered only outside the United States.

                  Until exchanged in full as hereinabove provided, the temporary
Securities  of any series shall in all respects be entitled to the same benefits
under this  Indenture as  definitive  Securities  of the same series and of like
tenor  authenticated  and delivered  hereunder,  except that,  unless  otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest  Payment Date for  Securities  of such series  occurring
prior to the applicable Exchange Date shall be payable to Euroclear and CEDEL on
such  Interest  Payment Date upon delivery by Euroclear and CEDEL to the Trustee
of a certificate  or  certificates  in the form set forth in Exhibit A-2 to this
Indenture  (or in such other  forms as may be  established  pursuant  to Section
301), for credit without further interest on or after such Interest Payment Date
to the  respective  accounts  of persons who are the  beneficial  owners of such
temporary  global  Security  on such  Interest  Payment  Date and who have  each
delivered  to  Euroclear or CEDEL,  as the case may be, a  certificate  dated no
earlier than 15 days prior to the Interest  Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit A-1 to this Indenture (or in such
other  forms as may be  established  pursuant to Section  301).  Notwithstanding
anything to the contrary herein contained,  the certifications  made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section 304 (b) and of the third  paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners of
a temporary  global Security with respect to which such  certification  was made
will be exchanged for definitive Securities of the same series and of like tenor
on the Exchange Date or the date of  certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners.  Except as
otherwise provided in this paragraph, no payments of principal or interest owing
with respect to a beneficial  interest in a temporary  global  Security  will be
made unless and until such interest in such temporary global Security shall have
been  exchanged  for an  interest  in a  definitive  Security.  Any  interest so
received  by  Euroclear  and  CEDEL  and not paid as  herein  provided  shall be
returned to the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company.

                  SECTION  305.  Registration,   Registration  of  Transfer  and
Exchange.  The Company shall cause to be kept at the  Corporate  Trust Office of
the  Trustee or in any  office or agency of the  Company in a Place of Payment a
register for each series of Securities (the registers  maintained in such office
or in any such  office or  agency of the  Company  in a Place of  Payment  being
herein sometimes referred to collectively as the "Security  Register") in which,
subject to such  reasonable  regulations as it may prescribe,  the Company shall
provide for the  registration  of  Registered  Securities  and of  transfers  of
Registered  Securities.  The Security  Register  shall be in written form or any
other form
                                       18
<PAGE>

capable of being  converted  into  written form within a  reasonable  time.  The
Trustee,  at its Corporate Trust Office, is hereby initially appointed "Security
Registrar" for the purpose of registering Registered Securities and transfers of
Registered Securities on such Security Register as herein provided. In the event
that the Trustee shall cease to be Security  Registrar,  it shall have the right
to examine the Security Register at all reasonable times.

                  Subject to the  provisions of this Section 305, upon surrender
for  registration  of transfer of any  Registered  Security of any series at any
office or agency of the  Company  in a Place of  Payment  for that  series,  the
Company shall execute,  and the Trustee shall  authenticate and deliver,  in the
name of the  designated  transferee or  transferees,  one or more new Registered
Securities of the same series,  of any  authorized  denominations  and of a like
aggregate principal amount, bearing a number not contemporaneously  outstanding,
and containing identical terms and provisions.

                  Subject to the  provisions  of this Section 305, at the option
of the Holder,  Registered  Securities  of any series may be exchanged for other
Registered  Securities of the same series,  of any  authorized  denomination  or
denominations  and of a like aggregate  principal amount,  containing  identical
terms  and  provisions,  upon  surrender  of  the  Registered  Securities  to be
exchanged at any such office or agency.  Whenever any such Registered Securities
are so  surrendered  for exchange,  the Company shall  execute,  and the Trustee
shall  authenticate  and deliver,  the  Registered  Securities  which the Holder
making the  exchange is entitled to receive.  Unless  otherwise  specified  with
respect to any series of  Securities  as  contemplated  by Section  301,  Bearer
Securities may not be issued in exchange for Registered Securities.

                  If (but only if) permitted by the applicable  Board Resolution
and (subject to Section 303) set forth in the applicable Officers'  Certificate,
or in any indenture  supplemental  hereto,  delivered as contemplated by Section
301,  at the  option of the  Holder,  Bearer  Securities  of any  series  may be
exchanged  for  Registered  Securities  of the  same  series  of any  authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Bearer Securities to be exchanged at any such office or agency,  with all
unmatured  coupons and all matured coupons in default thereto  appertaining.  If
the Holder of a Bearer  Security is unable to produce any such unmatured  coupon
or coupons or matured coupon or coupons in default,  any such permitted exchange
may be effected if the Bearer  Securities  are  accompanied  by payment in funds
acceptable  to the Company in an amount equal to the face amount of such missing
coupon or coupons,  or the  surrender of such  missing  coupon or coupons may be
waived  by the  Company  and the  Trustee  if there is  furnished  to them  such
security  or  indemnity  as they may require to save each of them and any Paying
Agent harmless. If thereafter the Holder of such Security shall surrender to any
Paying  Agent any such missing  coupon in respect of which such a payment  shall
have been made,  such  Holder  shall be  entitled  to receive the amount of such
payment; provided,  however, that, except as otherwise provided in Section 1002,
interest  represented  by coupons  shall be payable only upon  presentation  and
surrender  of those  coupons at an office or agency  located  outside the United
States.  Notwithstanding the foregoing,  in case a Bearer Security of any series
is  surrendered  at any such  office  or agency in a  permitted  exchange  for a
Registered  Security  of the same  series  and like  tenor  after  the  close of
business at such office or agency on (i) any Regular  Record Date and before the
opening of business at such office or agency on the  relevant  Interest  Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer  Security shall be surrendered  without the coupon  relating to such
Interest  Payment  Date or proposed  date for  payment,  as the case may be, and
interest or Defaulted Interest,  as the case may be, will not be payable on such
Interest  Payment  Date or  proposed  date for  payment,  as the case may be, in
respect of the Registered  Security issued in exchange for such Bearer Security,
but will be payable  only to the Holder of such  coupon  when due in  accordance
with the  provisions of this  Indenture.  Whenever any Bearer  Securities are so
surrendered  for  exchange,  the Company  shall  execute,  and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

                  Notwithstanding  the foregoing,  except as otherwise specified
as  contemplated  by  Section  301,  any  permanent  global  Security  shall  be
exchangeable  only as  provided in this  paragraph.  If the  depositary  for any
permanent global Security is DTC, then, unless the terms of such global Security
expressly  permit such global  Security to be  exchanged in whole or in part for
definitive Securities, a global Security may be transferred, in whole but not in
part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor
to DTC for such  global  Security  selected  or  approved by the Company or to a
nominee of such successor to DTC. If at any time DTC notifies the Company that

                                       19
<PAGE>

it is unwilling or unable to continue as depositary  for the  applicable  global
Security  or  Securities  or if at any time DTC ceases to be a  clearing  agency
registered under the Securities Exchange Act of 1934, as amended, if so required
by  applicable  law  or  regulation,  the  Company  shall  appoint  a  successor
depositary  with  respect  to  such  global  Security  or  Securities.  If (x) a
successor  depositary for such global Security or Securities is not appointed by
the  Company  within 90 days after the Company  receives  such notice or becomes
aware of such unwillingness, inability or ineligibility, (y) an Event of Default
has occurred and is continuing and the beneficial owners representing a majority
in principal amount of the applicable  series of Securities  represented by such
global Security or Securities  advise DTC to cease acting as depositary for such
global  Security  or  Securities  or (z) the  Company,  in its sole  discretion,
determines at any time that all  Outstanding  Securities (but not less than all)
of any series  issued or issuable  in the form of one or more global  Securities
shall no longer be represented by such global  Security or Securities,  then the
Company  shall  execute,   and  the  Trustee  shall  authenticate  and  deliver,
definitive  Securities of like series,  rank, tenor and terms in definitive form
in an aggregate  principal  amount equal to the principal  amount of such global
Security or Securities.  If any  beneficial  owner of an interest in a permanent
global  Security is otherwise  entitled to exchange such interest for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination,  as specified as contemplated by Section 301 and provided that
any applicable  notice provided in the permanent global Security shall have been
given,  then  without  unnecessary  delay  but in any  event no  later  than the
earliest  date on which such  interest may be so  exchanged,  the Company  shall
execute, and the Trustee shall authenticate and deliver,  definitive  Securities
in aggregate  principal  amount equal to the principal amount of such beneficial
owner's  interest in such permanent  global  Security.  On or after the earliest
date on which such interests may be so exchanged, such permanent global Security
shall be  surrendered  for exchange by DTC or such other  depositary as shall be
specified  in the Company  Order with  respect  thereto to the  Trustee,  as the
Company's agent for such purpose; provided,  however, that no such exchanges may
occur  during a period  beginning  at the opening of business 15 days before any
selection of  Securities  to be redeemed  and ending on the relevant  Redemption
Date if the Security for which exchange is requested may be among those selected
for  redemption;  and  provided  further  that no Bearer  Security  delivered in
exchange  for a  portion  of a  permanent  global  Security  shall be  mailed or
otherwise  delivered  to any  location  in the United  States.  If a  Registered
Security is issued in exchange  for any portion of a permanent  global  Security
after the close of business at the office or agency where such  exchange  occurs
on (i) any Regular Record Date and before the opening of business at such office
or agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and  before the  opening of  business  at such  office or agency on the  related
proposed date for payment of Defaulted Interest, interest or Defaulted Interest,
as the case  may be,  will  not be  payable  on such  Interest  Payment  Date or
proposed  date for  payment,  as the case may be, in respect of such  Registered
Security, but will be payable on such Interest Payment Date or proposed date for
payment,  as the case may be, only to the Person to whom  interest in respect of
such portion or such permanent global Security is payable in accordance with the
provisions of this Indenture.

                  All  Securities  issued upon any  registration  of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing
the same debt,  and entitled to the same benefits under this  Indenture,  as the
Securities surrendered upon such registration of transfer or exchange.

                  Every  Registered   Security   presented  or  surrendered  for
registration of transfer or for exchange or redemption  shall (if so required by
the Company or the Security Registrar) be duly endorsed,  or be accompanied by a
written  instrument  of  transfer  in form  satisfactory  to the Company and the
Security  Registrar,  duly  executed by the Holder  thereof or his attorney duly
authorized in writing.

                  No  service  charge  shall  be made  for any  registration  of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental  charge that may be imposed in
connection with any  registration  of transfer or exchange of Securities,  other
than  exchanges  pursuant to Section 304,  906,  1107 or 1305 not  involving any
transfer.

                  The  Company  or the  Trustee,  as  applicable,  shall  not be
required (i) to issue, register the transfer of or exchange any Security if such
Security may be among those selected for redemption during a period beginning at
the  opening of  business  15 days  before  selection  of the  Securities  to be
redeemed  under  Section 1103 and ending at the close of business on (A) if such
Securities are issuable only as Registered Securities, the day of the mailing of
the relevant  notice of redemption  and (B) if such  Securities  are issuable as
Bearer Securities, the day of the first publication of the

                                       20
<PAGE>

relevant  notice of  redemption  or, if such  Securities  are also  issuable  as
Registered  Securities and there is no publication,  the mailing of the relevant
notice of  redemption,  or (ii) to register  the  transfer  of or  exchange  any
Registered  Security so selected for redemption in whole or in part,  except, in
the case of any Registered  Security to be redeemed in part, the portion thereof
not to be  redeemed,  or (iii) to exchange  any Bearer  Security so selected for
redemption  except that such a Bearer Security may be exchanged for a Registered
Security  of that  series  and of like  tenor;  provided  that  such  Registered
Security shall be simultaneously  surrendered for redemption,  or (iv) to issue,
register the transfer of or exchange any Security which has been surrendered for
repayment  at the option of the  Holder,  except that  portion,  if any, of such
Security which is not to be so repaid.

                  SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.
If any mutilated Security or a Security with a mutilated coupon  appertaining to
it is surrendered to the Trustee or the Company, together with, in proper cases,
such  security or  indemnity as may be required by the Company or the Trustee to
save each of them or any agent of either of them  harmless,  the  Company  shall
execute and the Trustee shall  authenticate  and deliver in exchange  therefor a
new Security of the same series and principal amount, containing identical terms
and  provisions  and bearing a number not  contemporaneously  outstanding,  with
coupons  corresponding to the coupons,  if any,  appertaining to the surrendered
Security.

                  If there shall be  delivered to the Company and to the Trustee
(i)  evidence to their  satisfaction  of the  destruction,  loss or theft of any
Security or coupon,  and (ii) such  security or  indemnity as may be required by
them to save each of them and any agent of either of them harmless, then, in the
absence of written  notice to the Company or the Trustee  that such  Security or
coupon has been acquired by a bona fide purchaser, the Company shall execute and
upon its request the Trustee shall authenticate and deliver, in lieu of any such
destroyed,  lost or stolen  Security or in exchange  for the Security to which a
destroyed,  lost or stolen coupon  appertains (with all appurtenant  coupons not
destroyed,  lost or stolen),  a new  Security  of the same series and  principal
amount,  containing  identical  terms and  provisions  and  bearing a number not
contemporaneously  outstanding,  with coupons  corresponding to the coupons,  if
any, appertaining to such destroyed,  lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains.

                  Notwithstanding the provisions of the previous two paragraphs,
in case any such  mutilated,  destroyed,  lost or stolen  Security or coupon has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, with coupons corresponding to the coupons, if
any, appertaining to such destroyed,  lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains,  pay such Security or
coupon;  provided,  however, that payment of principal of (and premium, if any),
any interest on and any  Additional  Amounts with respect to, Bearer  Securities
shall,  except as  otherwise  provided in Section  1002,  be payable  only at an
office or agency  located  outside  the  United  States  and,  unless  otherwise
specified as  contemplated  by Section  301,  any interest on Bearer  Securities
shall  be  payable  only  upon   presentation   and  surrender  of  the  coupons
appertaining thereto.

                  Upon the issuance of any new Security under this Section,  the
Company may require  the payment of a sum  sufficient  to cover any tax or other
governmental  charge  that may be  imposed  in  relation  thereto  and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                  Every new  Security  of any series with its  coupons,  if any,
issued  pursuant  to  this  Section  in lieu of any  destroyed,  lost or  stolen
Security,  or in exchange  for a Security to which a  destroyed,  lost or stolen
coupon  appertains,   shall  constitute  an  original   additional   contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security
and its coupons, if any, or the destroyed, lost or stolen coupon shall be at any
time  enforceable  by anyone,  and shall be entitled to all the benefits of this
Indenture equally and proportionately  with any and all other Securities of that
series and their coupons, if any, duly issued hereunder.

                  The  provisions  of  this  Section  are  exclusive  and  shall
preclude (to the extent  lawful) all other  rights and remedies  with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities or
coupons.

                  SECTION 307. Payment of Interest;  Interest Rights  Preserved.
Except  as  otherwise  specified  with  respect  to a series  of  Securities  in
accordance  with the  provisions  of Section  301,  interest  on any  Registered
Security that

                                       21
<PAGE>

is payable, and is punctually paid or duly provided for, on any Interest Payment
Date  shall be paid to the Person in whose  name that  Security  (or one or more
Predecessor  Securities)  is  registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Company  maintained
for such  purpose  pursuant  to  Section  1002;  provided,  however,  that  each
installment of interest on any Registered  Security may at the Company's  option
be paid by (i) mailing a check for such interest, payable to or upon the written
order of the Person entitled  thereto pursuant to Section 308, to the address of
such  Person as it appears  on the  Security  Register  or (ii)  transfer  to an
account maintained by the payee located inside the United States.

                  Unless otherwise  provided as contemplated by Section 301 with
respect to the Securities of any series, payment of interest may be made, in the
case of a Bearer  Security,  by transfer to an account  maintained  by the payee
with a bank located outside the United States.

                  Unless  otherwise  provided as  contemplated  by Section  301,
every permanent  global Security will provide that interest,  if any, payable on
any Interest  Payment Date will be paid to DTC,  Euroclear  and/or CEDEL, as the
case may be, with respect to that portion of such permanent global Security held
for its account by Cede & Co. or the Common Depositary,  as the case may be, for
the purpose of  permitting  such party to credit the interest  received by it in
respect of such  permanent  global  Security to the  accounts of the  beneficial
owners thereof.

                  In case a Bearer  Security  of any  series is  surrendered  in
exchange  for a  Registered  Security of such series after the close of business
(at an office or agency in a Place of Payment  for such  series) on any  Regular
Record Date and before the opening of business (at such office or agency) on the
next succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest  Payment Date and interest will not
be payable on such Interest  Payment Date in respect of the Registered  Security
issued in exchange  for such Bearer  Security,  but will be payable  only to the
Holder  of such  coupon  when  due in  accordance  with the  provisions  of this
Indenture.

                  Except as  otherwise  specified  with  respect  to a series of
Securities in accordance with the provisions of Section 301, any interest on any
Registered Security of any series that is payable, but is not punctually paid or
duly  provided  for, on any  Interest  Payment Date  (herein  called  "Defaulted
Interest") shall forthwith cease to be payable to the registered  Holder thereof
on the relevant  Regular  Record Date by virtue of having been such Holder,  and
such  Defaulted  Interest  may be paid by the  Company,  at its election in each
case, as provided in clause (1) or (2) below:

                           (1) The  Company  may  elect to make  payment  of any
         Defaulted  Interest  to the  Persons  in  whose  names  the  Registered
         Securities of such series (or their respective Predecessor  Securities)
         are  registered  at the close of business on a Special  Record Date for
         the  payment of such  Defaulted  Interest,  which shall be fixed in the
         following  manner.  The Company  shall notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each Registered
         Security of such  series and the date of the  proposed  payment  (which
         shall not be less than 20 days after  such  notice is  received  by the
         Trustee),  and at the same  time the  Company  shall  deposit  with the
         Trustee an amount of money in the currency or currencies, currency unit
         or units or composite currency or currencies in which the Securities of
         such  series are payable  (except as  otherwise  specified  pursuant to
         Section 301 for the  Securities  of such series) equal to the aggregate
         amount  proposed  to be paid in respect of such  Defaulted  Interest or
         shall make arrangements satisfactory to the Trustee for such deposit on
         or prior to the date of the proposed payment, such money when deposited
         to be held in trust for the  benefit of the  Persons  entitled  to such
         Defaulted  Interest as in this clause  provided.  Thereupon the Trustee
         shall fix a  Special  Record  Date for the  payment  of such  Defaulted
         Interest which shall not be more than 15 days and not less than 10 days
         prior to the date of the  proposed  payment  and not less  than 10 days
         after the receipt by the Trustee of the notice of the proposed payment.
         The Trustee shall  promptly  notify the Company of such Special  Record
         Date and,  in the name and at the expense of the  Company,  shall cause
         notice of the  proposed  payment  of such  Defaulted  Interest  and the
         Special Record Date therefor to be mailed, first-class postage prepaid,
         to each Holder of  Registered  Securities of such series at his address
         as it appears in the  Security  Register not less than 10 days prior to
         such Special  Record Date. The Trustee may, in its  discretion,  in the
         name and at the expense of the  Company,  cause a similar  notice to be
         published  at least once in an  Authorized  Newspaper  in each Place of
         Payment,  but such publications  shall not be a condition  precedent to
         the  establishment of such Special Record Date.  Notice of the proposed
         payment of such Defaulted Interest and

                                       22
<PAGE>
         the Special Record Date therefor having been mailed as aforesaid,  such
         Defaulted  Interest  shall be paid to the  Persons  in whose  names the
         Registered  Securities of such series (or their respective  Predecessor
         Securities)  are  registered  at the close of business on such  Special
         Record Date and shall no longer be payable  pursuant  to the  following
         clause (2). In case a Bearer  Security of any series is surrendered for
         transfer  or exchange at the office or agency in a Place of Payment for
         such series after the close of business at such office or agency on any
         Special  Record  Date and before the opening of business at such office
         or  agency  on the  related  proposed  date for  payment  of  Defaulted
         Interest,  such Bearer Security shall be surrendered without the coupon
         relating to such proposed  date of payment and Defaulted  Interest will
         not be  payable  on such  proposed  date of  payment  in respect of the
         Registered  Security issued in exchange for such Bearer  Security,  but
         will  be  payable  only  to the  Holder  of  such  coupon  when  due in
         accordance with the provisions of this Indenture.

                           (2) The  Company  may make  payment of any  Defaulted
         Interest on the Registered Securities of any series in any other lawful
         manner  not  inconsistent  with  the  requirements  of  any  securities
         exchange on which such  Securities may be listed,  and upon such notice
         as may be required by such  exchange,  if,  after  notice  given by the
         Company to the Trustee of the proposed payment pursuant to this clause,
         such manner of payment shall be deemed practicable by the Trustee.

                  Subject  to the  foregoing  provisions  of  this  Section  and
Section 305, each Security  delivered under this Indenture upon  registration of
transfer of or in exchange for or in lieu of any other  Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

                  SECTION 308.  Persons Deemed Owners.  Prior to due presentment
of a Registered Security for registration of transfer,  the Company, the Trustee
and any agent of the  Company or the  Trustee may treat the Person in whose name
such  Registered  Security is  registered  as the owner of such Security for the
purpose of receiving payment of principal of (and premium, if any), and (subject
to Sections 305 and 307) interest on, such Registered Security and for all other
purposes  whatsoever,  whether or not such Registered  Security is overdue,  and
neither  the  Company,  the  Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

                  Title to any  Bearer  Security  and any  coupons  appertaining
thereto  shall pass by delivery.  The Company,  the Trustee and any agent of the
Company  or the  Trustee  may treat the Holder of any  Bearer  Security  and the
Holder of any coupon as the  absolute  owner of such  Security or coupon for the
purpose of  receiving  payment  thereof or on account  thereof and for all other
purposes  whatsoever,  whether or not such  Security or coupon is  overdue,  and
neither  the  Company,  the  Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

                  None of the  Company,  the  Trustee,  any Paying  Agent or the
Security  Registrar will have any  responsibility or liability for any aspect of
the  records  relating to or payments  made on account of  beneficial  ownership
interests  of a  Security  in global  form or for  maintaining,  supervising  or
reviewing any records relating to such beneficial ownership interests.

                  Notwithstanding  the  foregoing,  with  respect  to any global
Security, nothing herein shall prevent the Company, the Trustee, or any agent of
the Company or the  Trustee,  from giving  effect to any written  certification,
proxy or other  authorization  furnished by any  depositary,  as a Holder,  with
respect to such global Security or impair, as between such depositary and owners
of  beneficial  interests in such global  Security,  the  operation of customary
practices  governing  the  exercise  of the  rights of such  depositary  (or its
nominee) as Holder of such global Security.

                  SECTION  309.   Cancellation.   All   Securities  and  coupons
surrendered  for  payment,  redemption,  repayment  at the option of the Holder,
registration  of transfer or  exchange  or for credit  against any sinking  fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee,  and any such  Securities and coupons and Securities and coupons
surrendered  directly  to the  Trustee  for any such  purpose  shall be promptly
cancelled  by it.  The  Company  may at any  time  deliver  to the  Trustee  for
cancellation any Securities  previously  authenticated  and delivered  hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the  Trustee  (or  to  any  other  Person  for  delivery  to  the  Trustee)  for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold,  and all  Securities  so  delivered  shall be  promptly
cancelled by the Trustee.

                                       23
<PAGE>

If the Company shall so acquire any of the Securities, however, such acquisition
shall  not  operate  as  a  redemption  or  satisfaction  of  the   indebtedness
represented by such Securities  unless and until the same are surrendered to the
Trustee for cancellation.  No Securities shall be authenticated in lieu of or in
exchange for any  Securities  cancelled as provided in this  Section,  except as
expressly permitted by this Indenture.  Cancelled Securities and coupons held by
the Trustee  shall be destroyed by the Trustee and the Trustee  shall  deliver a
certificate of such  destruction  to the Company,  unless by a Company Order the
Company directs their return to it.

                  SECTION  310.  Computation  of  Interest.  Except as otherwise
specified  as  contemplated  by Section 301 with  respect to  Securities  of any
series, interest on the Securities of each series shall be computed on the basis
of a 360-day year consisting of twelve 30-day months.


                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

                  SECTION 401.  Satisfaction  and Discharge of  Indenture.  This
Indenture  shall upon Company Request cease to be of further effect with respect
to any series of Securities  specified in such Company Request (except as to any
surviving  rights of  registration of transfer or exchange of Securities of such
series  herein  expressly  provided  for and any  right  to  receive  Additional
Amounts,  as provided  in Section  1007),  and the  Trustee,  upon  receipt of a

                  Company and  thereafter  repaid to the  Company or  discharged

                  currency or  currencies,  currency  unit or units or composite
                  currency or currencies in which the  Securities of such series

                  payable,   sufficient   to  pay  and   discharge   the  entire
                  indebtedness   on  such   Securities   and  such  coupons  not
                  theretofore  delivered  to the Trustee for  cancellation,  for

                  Additional  Amounts with respect thereto,  to the date of such
                  deposit (in the case of  Securities  which have become due and
                  payable) or to the Stated Maturity or Redemption  Date, as the
                  case may be;

                  (2) the  Company  has paid or caused to be paid all other sums
         payable hereunder by the Company; and

                  (3) the Company  has  delivered  to the  Trustee an  Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent   herein  provided  for  relating  to  the  satisfaction  and
         discharge of this Indenture as to such series have been complied with.

The obligations of the Company to the Trustee and any predecessor  Trustee under
Section 606, the  obligations of the Company to any  Authenticating  Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section,  the obligations of the

provisions of the last paragraph of Section 1003,  all money  deposited with the

Indenture,  to  the  payment,  either  directly  or  through  any  Paying  Agent
(including  the  Company  acting as its own  Paying  Agent) as the  Trustee  may
determine,  to the Persons entitled thereto,  of the principal (and premium,  if
any), and any interest and  Additional  Amounts for whose payment such money has
been  deposited  with or  received  by the  Trustee,  but such money need not be
segregated from other funds except to the extent required by law.

                                    REMEDIES

                  SECTION 501. Events of Default.  "Event of Default",  wherever
used herein with respect to any particular  series of Securities,  means any one
of the  following  events  (whatever  the reason  for such Event of Default  and
whether or not it shall be voluntary or  involuntary or be effected by operation
of law or pursuant to any  judgment,  decree or order of any court or any order,
rule or regulation of any administrative or governmental body):

                  (1)  default  in the  payment  of  any  interest  upon  or any
         Additional Amounts payable in respect of any Security of that series or
         of any coupon  appertaining  thereto,  when such  interest,  Additional
         Amounts or coupon  becomes due and  payable,  and  continuance  of such
         default for a period of 30 days; or

                  (2) default in the payment of the principal of (or premium, if
         any, on) any Security of that series when it becomes due and payable at
         its Maturity; or

                  (3) default in the deposit of any sinking fund  payment,  when
         and as due by the terms of any Security of that series; or

                  (4) default in the  performance of, or breach of, any covenant
         of the  Company in this  Indenture  (other than a covenant a default in
         whose  performance  or  whose  breach  is  elsewhere  in  this  Section
         specifically  dealt with or which has been  expressly  included in this
         Indenture  solely for the benefit of a series of Securities  other than
         that series), and continuance of such default or breach for a period of
         60 days after there has been given, by registered or certified mail, to
         the  Company by the  Trustee or to the  Company  and the Trustee by the
         Holders of at least a majority in principal  amount of the  Outstanding
         Securities of that series a

                                       25
<PAGE>
         written notice specifying such default or breach and requiring it to be
         remedied  and  stating  that  such  notice  is a  "Notice  of  Default"
         hereunder; or

                  (5) a  default  under  any  bond,  debenture,  note  or  other
         evidence  of  indebtedness  of the  Company,  or  under  any  mortgage,
         indenture or other instrument of the Company  (including a default with
         respect to Securities of any series other than that series) under which
         there may be issued or by which there may be secured  any  indebtedness
         of the  Company  (or by any  Subsidiary,  the  repayment  of which  the
         Company has guaranteed or for which the Company is directly responsible
         or liable as obligor  or  guarantor),  whether  such  indebtedness  now
         exists or shall hereafter be created,  which default shall constitute a
         failure to pay an aggregate  principal amount exceeding  $25,000,000 of
         such  indebtedness  when due and payable  after the  expiration  of any
         applicable grace period with respect thereto and shall have resulted in
         such   indebtedness  in  an  aggregate   principal   amount   exceeding
         $25,000,000  becoming or being  declared  due and payable  prior to the
         date on which it would  otherwise have become due and payable,  without
         such indebtedness  having been discharged,  or such acceleration having
         been  rescinded  or  annulled,  within a period of 10 days after  there
         shall have been given,  by registered or certified mail, to the Company
         by the  Trustee or to the  Company and the Trustee by the Holders of at
         least a majority in principal  amount of the Outstanding  Securities of
         that series a written notice  specifying such default and requiring the
         Company  to cause  such  indebtedness  to be  discharged  or cause such
         acceleration  to be  rescinded or annulled and stating that such notice
         is a "Notice of Default" hereunder; or

                  (6) the Company or any Significant  Subsidiary  pursuant to or
         within the meaning of any Bankruptcy Law:

                           (A) commences a voluntary case,

                           (B)  consents  to the  entry of an order  for  relief
                  against it in an involuntary case,

                           (C) consents to the  appointment of a Custodian of it
                  or for all or substantially all of its property, or

                           (D) makes a general assignment for the benefit of its
                  creditors; or

                  (7) a court  of  competent  jurisdiction  enters  an  order or
         decree under any Bankruptcy Law that:

                           (A)  is  for  relief   against  the  Company  or  any
                  Significant Subsidiary in an involuntary case,

                           (B)  appoints  a  Custodian  of  the  Company  or any
                  Significant  Subsidiary  or for  all or  substantially  all of
                  either of its property, or

                           (C)  orders  the  liquidation  of the  Company or any
                  Significant  Subsidiary,  and  the  order  or  decree  remains
                  unstayed and in effect for 90 days; or

                  (8) any  other  Event of  Default  provided  with  respect  to
         Securities of that series.

As used in this Section 501, the term "Bankruptcy Law" means Title 11, U.S. Code
or any  similar  Federal  or State law for the  relief of  debtors  and the term
"Custodian" means any receiver,  trustee, assignee,  liquidator or other similar
official under any Bankruptcy Law.

                  SECTION  502.   Acceleration   of  Maturity;   Rescission  and
Annulment.  If an Event of Default with respect to  Securities  of any series at
the time  Outstanding  occurs and is continuing  (other than an Event of Default
described in Section 501(6) or 501(7)),  then and in every such case the Trustee
or the Holders of not less than a majority

                                       26
<PAGE>
in principal amount of the Outstanding Securities of that series may declare the
principal  (or, if any  Securities  are Original  Issue  Discount  Securities or
Indexed  Securities,  such  portion of the  principal as may be specified in the
terms  thereof)  of all the  Securities  of that  series  to be due and  payable
immediately,  by a notice in writing to the Company (and to the Trustee if given
by the  Holders),  and upon any such  declaration  such  principal  or specified
portion thereof shall become immediately due and payable. If an Event of Default
described in Section  501(6) or 501(7) with respect to any series of  Securities
at the time outstanding occurs, the principal amount of all of the Securities of
that series (or, in the case of any such Original Issue  Discount  Securities or
Indexed  Securities,  such  portion of the  principal as may be specified in the
terms thereof) will automatically,  and without any action by the Trustee or any
Holder thereof, become immediately due and payable.

                  At any time  after such a  declaration  of  acceleration  with
respect to  Securities  of any  series  has been made and  before a judgment  or
decree  for  payment  of the  money  due has been  obtained  by the  Trustee  as
hereinafter  in this  Article  provided,  the Holders of a majority in principal
amount of the  Outstanding  Securities of that series,  by written notice to the
Company  and the  Trustee,  may  rescind  and  annul  such  declaration  and its
consequences if:

                  (1) the Company has paid or  deposited  with the Trustee a sum
         sufficient to pay in the currency,  currency unit or composite currency
         in which the Securities of such series are payable (except as otherwise
         specified pursuant to Section 301 for the Securities of such series):

                           (A) all overdue  installments  of interest on and any
                  Additional  Amounts  payable  in  respect  of all  Outstanding
                  Securities of that series and any related coupons,

                           (B) the  principal of (and  premium,  if any, on) any
                  Outstanding  Securities  of that series  which have become due
                  otherwise  than  by  such   declaration  of  acceleration  and
                  interest thereon at the rate or rates borne by or provided for
                  in such Securities,

                           (C) to the extent  that  payment of such  interest is
                  lawful, interest upon overdue installments of interest and any
                  Additional  Amounts at the rate or rates  borne by or provided
                  for in such Securities, and

                           (D)  all  sums  paid  or   advanced  by  the  Trustee
                  hereunder   and   the   reasonable   compensation,   expenses,
                  disbursements  and  advances  of the  Trustee,  its agents and
                  counsel; and

                  (2) all Events of Default with respect to  Securities  of that
         series,  other than the nonpayment of the principal of (or premium,  if
         any) or interest  on  Securities  of that series  which have become due
         solely by such declaration of  acceleration,  have been cured or waived
         as provided in Section 513.

No such  rescission  shall  affect  any  subsequent  default or impair any right
consequent thereon.

                  SECTION  503.   Collection  of  Indebtedness   and  Suits  for
Enforcement by Trustee. The Company covenants that if:

                  (1)  default  is made in the  payment  of any  installment  of
         interest or Additional  Amounts,  if any, on any Security of any series
         and any related coupon when such interest or Additional  Amount becomes
         due and payable and such default continues for a period of 30 days, or

                  (2)  default is made in the  payment of the  principal  of (or
         premium, if any, on) any Security of any series at its Maturity,

then the Company will, upon demand of the Trustee,  pay to the Trustee,  for the
benefit of the Holders of such Securities of such series and coupons,  the whole
amount then due and payable on such  Securities  and coupons for principal  (and
premium, if any) and interest and Additional Amounts thereon, with interest upon
any overdue  principal (and premium,  if any) and, to the extent that payment of
such interest shall be legally enforceable, upon any overdue installments of

                                       27
<PAGE>
interest or Additional Amounts thereon, if any, at the rate or rates borne by or
provided for in such Securities,  and, in addition thereto,  such further amount
as shall be sufficient to cover the costs and expenses of collection,  including
the  reasonable  compensation,  expenses,  disbursements  and  advances  of  the
Trustee, its agents and counsel.

                  If the Company fails to pay such amounts  forthwith  upon such
demand,  the Trustee,  in its own name and as trustee of an express  trust,  may
institute  a  judicial  proceeding  for the  collection  of the  sums so due and
unpaid,  and may prosecute such proceeding to judgment or final decree,  and may
enforce the same against the Company or any other  obligor upon such  Securities
of such series and  collect the moneys  adjudged or decreed to be payable in the
manner  provided by law out of the property of the Company or any other  obligor
upon such Securities of such series, wherever situated.

                  If an Event of  Default  with  respect  to  Securities  of any
series occurs and is continuing,  the Trustee may in its  discretion  proceed to
protect and enforce  its rights and the rights of the Holders of  Securities  of
such series and any related coupons by such appropriate  judicial proceedings as
the Trustee  shall deem most  effectual  to protect and enforce any such rights,
whether  for the  specific  enforcement  of any  covenant or  agreement  in this
Indenture or in aid of the exercise of any power granted  herein,  or to enforce
any other proper remedy.

                  SECTION 504.  Trustee May File Proofs of Claim. In case of the
pendency   of   any   receivership,    insolvency,   liquidation,    bankruptcy,
reorganization,   arrangement,   adjustment,   composition   or  other  judicial
proceeding  relative to the Company or any other obligor upon the  Securities or
the  property of the Company or of such other  obligor or their  creditors,  the
Trustee  (irrespective  of whether the principal of the Securities of any series
shall  then be due  and  payable  as  therein  expressed  or by  declaration  or
otherwise and  irrespective of whether the Trustee shall have made any demand on
the  Company  for the payment of overdue  principal  of, or premium,  if any, or
interest on, the Securities) shall be entitled and empowered, by intervention in
such proceeding or otherwise:

                           (i) to file and prove a claim  for the whole  amount,
         or such lesser amount as may be provided for in the  Securities of such
         series, of principal (and premium,  if any) and interest and Additional
         Amount,  if any,  owing and unpaid in respect of the  Securities and to
         file such other papers or documents as may be necessary or advisable in
         order to have the claims of the  Trustee  (including  any claim for the
         reasonable  compensation,  expenses,  disbursements and advances of the
         Trustee,  its agents and  counsel)  and of the Holders  allowed in such
         judicial proceeding, and

                           (ii) to  collect  and  receive  any  moneys  or other
         property  payable or  deliverable  on any such claims and to distribute
         the same;

and any custodian,  receiver,  assignee, trustee,  liquidator,  sequestrator (or
other similar official) in any such judicial  proceeding is hereby authorized by
each Holder of  Securities  of such series and coupons to make such  payments to
the Trustee,  and in the event that the Trustee  shall  consent to the making of
such payments  directly to the Holders,  to pay to the Trustee any amount due to
it for the reasonable compensation,  expenses, disbursements and advances of the
Trustee and any  predecessor  Trustee,  their agents and counsel,  and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

                  Nothing  herein  contained  shall be deemed to  authorize  the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder of
a Security  or coupon any plan of  reorganization,  arrangement,  adjustment  or
composition  affecting  the  Securities  or  coupons or the rights of any Holder
thereof,  or to  authorize  the  Trustee  to vote in respect of the claim of any
Holder of a Security or coupon in any such proceeding.

                  SECTION 505. Trustee May Enforce Claims Without  Possession of
Securities or Coupons.  All rights of action and claims under this  Indenture or
any of the  Securities or coupons may be prosecuted  and enforced by the Trustee
without the  possession of any of the  Securities  or coupons or the  production
thereof in any proceeding relating thereto,  and any such proceeding  instituted
by the Trustee shall be brought in its own name as trustee of an express  trust,
and any  recovery  of judgment  shall,  after  provision  for the payment of the
reasonable compensation, expenses,

                                       28
<PAGE>
disbursements  and advances of the Trustee,  its agents and counsel,  be for the
ratable  benefit of the  Holders of  Securities  and coupons in respect of which
such judgment has been recovered.

                  SECTION  506.  Application  of  Money  Collected.   Any  money
collected  by the  Trustee  pursuant  to this  Article  shall be  applied in the
following  order,  at the date or dates fixed by the Trustee and, in case of the
distribution  of such money on  account of  principal  (or  premium,  if any) or
interest and any  Additional  Amounts,  upon  presentation  of the Securities or
coupons, or both, as the case may be, and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

                  FIRST:  To the  payment of all  amounts due to the Trustee and
         any predecessor Trustee under Section 606;

                  SECOND: To the payment of the amounts then due and unpaid upon
         the  Securities  and coupons for principal  (and  premium,  if any) and
         interest and any Additional Amounts payable, in respect of which or for
         the benefit of which such money has been  collected,  ratably,  without
         preference or priority of any kind,  according to the aggregate amounts
         due and  payable on such  Securities  and coupons  for  principal  (and
         premium, if any), interest and Additional Amounts, respectively; and

                  THIRD:  To  the  payment  of the  remainder,  if  any,  to the
         Company.

                  SECTION 507. Limitation on Suits. No Holder of any Security of
any  series  or any  related  coupon  shall  have  any  right to  institute  any
proceeding,  judicial or otherwise,  with respect to this Indenture,  or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless:

                  (1) such Holder has  previously  given  written  notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the  Holders  of not less  than a  majority  in  principal
         amount of the  Outstanding  Securities  of that series  shall have made
         written  request to the Trustee to institute  proceedings in respect of
         such Event of Default in its own name as Trustee hereunder;

                  (3)  such  Holder  or  Holders  have  offered  to the  Trustee
         reasonable indemnity against the costs,  expenses and liabilities to be
         incurred in compliance with such request;

                  (4) the Trustee for 60 days after its receipt of such  notice,
         request  and  offer of  indemnity  has  failed  to  institute  any such
         proceeding; and

                  (5) no direction  inconsistent  with such written  request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in  principal  amount of the  Outstanding  Securities  of that
         series;

it being  understood and intended that no one or more of such Holders shall have
any right in any manner  whatever by virtue of, or by availing of, any provision
of this  Indenture to affect,  disturb or  prejudice  the rights of any other of
such Holders,  or to obtain or to seek to obtain priority or preference over any
other of such  Holders or to enforce any right under this  Indenture,  except in
the manner  herein  provided  and for the equal and ratable  benefit of all such
Holders.

                  SECTION  508.   Unconditional  Right  of  Holders  to  Receive
Principal, Premium, if any, Interest and Additional Amounts. Notwithstanding any
other  provision in this  Indenture,  the Holder of any Security or coupon shall
have the right which is absolute  and  unconditional  to receive  payment of the
principal  of (and  premium,  if any)  and  (subject  to  Sections  305 and 307)
interest on, and any Additional  Amounts in respect of, such Security or payment
of such coupon on the respective due dates  expressed in such Security or coupon
(or, in the case of redemption,  on the  Redemption  Date) and to institute suit
for the  enforcement of any such payment,  and such rights shall not be impaired
without the consent of such Holder.

                                       29
<PAGE>
                  SECTION  509.  Restoration  of  Rights  and  Remedies.  If the
Trustee or any Holder of a Security or coupon has  instituted  any proceeding to
enforce any right or remedy under this  Indenture and such  proceeding  has been
discontinued or abandoned for any reason,  or has been  determined  adversely to
the  Trustee or to such  Holder,  then and in every such case the  Company,  the
Trustee  and the  Holders  of  Securities  and  coupons  shall,  subject  to any
determination  in such  proceeding,  be restored  severally and  respectively to
their former  positions  hereunder and thereafter all rights and remedies of the
Trustee and the Holders  shall  continue as though no such  proceeding  had been
instituted.

                  SECTION  510.  Rights  and  Remedies  Cumulative.   Except  as
otherwise  provided  with respect to the  replacement  or payment of  mutilated,
destroyed, lost or stolen Securities or coupons in the last paragraph of Section
306, no right or remedy herein  conferred  upon or reserved to the Trustee or to
the Holders of  Securities  or coupons is intended to be  exclusive of any other
right or remedy,  and every right and remedy shall,  to the extent  permitted by
law,  be  cumulative  and in  addition  to every  other  right and remedy  given
hereunder or now or  hereafter  existing at law or in equity or  otherwise.  The
assertion or employment of any right or remedy  hereunder,  or otherwise,  shall
not prevent the  concurrent  assertion or  employment  of any other  appropriate
right or remedy.

                  SECTION  511.  Delay  or  Omission  Not  Waiver.  No  delay or
omission of the  Trustee or of any Holder of any  Security or coupon to exercise
any right or remedy  accruing  upon any Event of Default  shall  impair any such
right or  remedy  or  constitute  a waiver of any such  Event of  Default  or an
acquiescence therein.  Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised  from time to time,  and as often
as may be deemed  expedient,  by the Trustee or by the Holders of  Securities or
coupons, as the case may be.

                  SECTION 512. Control by Holders of Securities.  The Holders of
not less than a majority in principal  amount of the  Outstanding  Securities of
any  series  shall  have the  right to  direct  the  time,  method  and place of
conducting any proceeding for any remedy  available to the Trustee or exercising
any trust or power  conferred on the Trustee with respect to the  Securities  of
such series; provided that

                  (1) such  direction  shall not be in conflict with any rule of
         law or with this Indenture,

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction, and

                  (3) the Trustee need not take any action which might expose it
         to  personal  liability  or be unduly  prejudicial  to the  Holders  of
         Securities of such series not joining therein.

                  SECTION 513. Waiver of Past Defaults.  The Holders of not less
than a majority in principal amount of the Outstanding  Securities of any series
may on  behalf of the  Holders  of all the  Securities  of such  series  and any
related coupons waive any past default hereunder with respect to such series and
its consequences, except a default

                  (1) in the payment of the principal of (or premium, if any) or
         interest on or Additional Amounts payable in respect of any Security of
         such series or any related coupons, or

                  (2) in respect of a covenant or  provision  hereof which under
         Article  Nine cannot be modified or amended  without the consent of the
         Holder of each Outstanding Security of such series affected.

         Upon any such waiver,  such default shall cease to exist, and any Event
of  Default  arising  therefrom  shall be deemed to have been  cured,  for every
purpose of this Indenture;  but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

                  SECTION  514.  Waiver of Usury,  Stay or Extension  Laws.  The
Company covenants (to the extent that it may lawfully do so) that it will not at
any time insist upon, or plead,  or in any manner  whatsoever  claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted,  now
or at any time  hereafter  in  force,  which may  affect  the  covenants  or the
performance  of this  Indenture;  and the  Company  (to the  extent  that it may
lawfully

                                       30
<PAGE>
do so) hereby  expressly  waives all benefit or  advantage  of any such law, and
covenants  that it will not hinder,  delay or impede the  execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law had been enacted.

                  SECTION  515.  Undertaking  for  Costs.  All  parties  to this
Indenture agree, and each Holder of any Security by his acceptance thereof shall
be deemed to have agreed,  that any court may in its discretion  require, in any
suit for the enforcement of any right or remedy under this Indenture,  or in any
suit against the Trustee for any action  taken or omitted by it as Trustee,  the
filing by any party  litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion  assess  reasonable  costs,
including  reasonable  attorneys' fees,  against any party litigant in such suit
having due regard to the merits and good faith of the claims or defenses made by
such party  litigant;  but the provisions of this Section shall not apply to any
suit instituted by the Trustee,  to any suit instituted by any Holder,  or group
of Holders, holding in the aggregate more than a majority in principal amount of
the  Outstanding  Securities,  or to any suit  instituted  by any Holder for the
enforcement of the payment of the principal of (or premium,  if any) or interest
on any Security on or after the respective Stated  Maturities  expressed in such
Security (or, in the case of redemption, on or after the Redemption Date).


                                   ARTICLE SIX

                                   THE TRUSTEE

                  SECTION  601.  Notice of  Defaults.  Within 90 days  after the
occurrence  of any  default  hereunder  with  respect to the  Securities  of any
series,  the Trustee shall transmit in the manner and to the extent  provided in
TIA Section  313(c),  notice of such  default  hereunder  known to the  Trustee,
unless such default shall have been cured or waived;  provided,  however,  that,
except in the case of a default in the payment of the  principal of (or premium,
if any) or interest on or any  Additional  Amounts or sinking  fund  installment
with respect to the Securities of such series, the Trustee shall be protected in
withholding such notice if and so long as Responsible Officers of the Trustee in
good faith  determine that the  withholding of such notice is in the interest of
the Holders of the Securities and coupons of such series;  and provided  further
that in the case of any default or breach of the character  specified in Section
501(4) with respect to the Securities and coupons of such series, no such notice
to Holders shall be given until at least 60 days after the  occurrence  thereof.
For the purpose of this Section, the term "default" means any event which is, or
after  notice or lapse of time or both would  become,  an Event of Default  with
respect to the Securities of such series.

                  SECTION  602.  Certain  Rights  of  Trustee.  Subject  to  the
provisions of TIA Section 315(a) through 315(d):

                  (1) the Trustee may rely and shall be  protected  in acting or
         refraining  from acting upon any  resolution,  certificate,  statement,
         instrument,  opinion,  report,  notice,  request,  direction,  consent,
         order,  bond,  debenture,  note,  coupon  or other  paper  or  document
         believed by it to be genuine and to have been  signed or  presented  by
         the proper party or parties;

                  (2) any request or direction of the Company  mentioned  herein
         shall be  sufficiently  evidenced by a Company Request or Company Order
         (other  than  delivery  of any  Security,  together  with  any  coupons
         appertaining  thereto,  to the Trustee for  authentication and delivery
         pursuant  to  Section  303 which  shall be  sufficiently  evidenced  as
         provided  therein) and any  resolution of the Board of Directors may be
         sufficiently evidenced by a Board Resolution;

                  (3)  whenever  in the  administration  of this  Indenture  the
         Trustee shall deem it desirable  that a matter be proved or established
         prior to taking,  suffering  or omitting to take any action  hereunder,
         the Trustee (unless other evidence be herein  specifically  prescribed)
         may,  in the absence of bad faith on its part,  rely upon an  Officers'
         Certificate;

                                       31
<PAGE>
                  (4) the  Trustee may  consult  with  counsel and the advice of
         such  counsel  or any  Opinion of  Counsel  shall be full and  complete
         authorization  and protection in respect of any action taken,  suffered
         or omitted by it hereunder in good faith and in reliance thereon;

                  (5) the Trustee  shall be under no  obligation to exercise any
         of the rights or powers  vested in it by this  Indenture at the request
         or direction of any of the Holders of  Securities  of any series or any
         related coupons  pursuant to this Indenture,  unless such Holders shall
         have offered to the Trustee  reasonable  security or indemnity  against
         the costs,  expenses and  liabilities  which might be incurred by it in
         compliance with such request or direction;

                  (6) the Trustee  shall not be bound to make any  investigation
         into the  facts  or  matters  stated  in any  resolution,  certificate,
         statement,  instrument,  opinion,  report, notice, request,  direction,
         consent,  order,  bond,  debenture,  note,  coupon  or  other  paper or
         document,  but the Trustee,  in its  discretion,  may make such further
         inquiry or investigation  into such facts or matters as it may see fit,
         and, if the Trustee  shall  determine to make such  further  inquiry or
         investigation,  it shall be entitled to examine the books,  records and
         premises of the Company, personally or by agent or attorney;

                  (7) the  Trustee  may  execute  any of the  trusts  or  powers
         hereunder  or perform  any duties  hereunder  either  directly or by or
         through  agents or attorneys and the Trustee  shall not be  responsible
         for any  misconduct  or negligence on the part of any agent or attorney
         appointed with due care by it hereunder; and

                  (8) the  Trustee  shall not be liable  for any  action  taken,
         suffered or omitted by it in good faith and  reasonably  believed by it
         to be authorized or within the discretion or rights or powers conferred
         upon it by this Indenture.

                  The  Trustee  shall not be  required to expend or risk its own
funds or otherwise  incur any financial  liability in the  performance of any of
its duties hereunder, or in the exercise of any of its rights or powers.

                  SECTION  603.  Not  Responsible  for  Recitals  or Issuance of
Securities.  The recitals  contained  herein and in the  Securities,  except the
Trustee's  certificate of  authentication,  and in any coupons shall be taken as
the  statements of the Company,  and neither the Trustee nor any  Authenticating
Agent assumes any  responsibility  for their  correctness.  The Trustee makes no
representations  as to the validity or  sufficiency  of this Indenture or of the
Securities  or  coupons,  except  that the  Trustee  represents  that it is duly
authorized to execute and deliver this  Indenture,  authenticate  the Securities
and   perform   its   obligations   hereunder.   Neither  the  Trustee  nor  the
Authenticating  Agent shall be  accountable  for the use or  application  by the
Company of Securities or the proceeds thereof.

                  SECTION 604.  May Hold  Securities.  The  Trustee,  any Paying
Agent,  Security  Registrar,  Authenticating  Agent  or any  other  agent of the
Company,  in its  individual  or any other  capacity,  may  become  the owner or
pledgee of Securities and coupons and,  subject to TIA Sections  310(b) and 311,
may  otherwise  deal with the  Company  with the same rights it would have if it
were not Trustee, Paying Agent, Security Registrar, Authenticating Agent or such
other agent.

                  SECTION 605. Money Held in Trust. Money held by the Trustee in
trust  hereunder  need not be  segregated  from other funds except to the extent
required by law.  The Trustee  shall be under no  liability  for interest on any
money received by it hereunder except as otherwise agreed with the Company.

                  SECTION  606.  Compensation  and  Reimbursement.  The  Company
agrees:

                  (1) to pay  to  the  Trustee  from  time  to  time  reasonable
         compensation   for  all  services   rendered  by  it  hereunder  (which
         compensation  shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

                                       32
<PAGE>
                  (2)  except  as  otherwise   expressly   provided  herein,  to
         reimburse  each of the Trustee  and any  predecessor  Trustee  upon its
         request  for  all  reasonable  expenses,   disbursements  and  advances
         incurred or made by the Trustee in  accordance  with any  provision  of
         this Indenture (including the reasonable  compensation and the expenses
         and disbursements of its agents and counsel),  except any such expense,
         disbursement or advance as may be attributable to its negligence or bad
         faith; and

                  (3) to  indemnify  each of the  Trustee  and  any  predecessor
         Trustee for, and to hold it harmless  against,  any loss,  liability or
         expense  incurred  without  negligence  or bad  faith on its own  part,
         arising out of or in connection  with the acceptance or  administration
         of the trust or trusts  hereunder,  including the costs and expenses of
         defending  itself against any claim or liability in connection with the
         exercise or performance of any of its powers or duties hereunder.

                  When the  Trustee  incurs  expenses  or  renders  services  in
connection  with an Event of  Default  specified  in  Section  501(6) or Section
501(7),  the  expenses  (including  the  reasonable  charges and expenses of its
counsel)  and the  compensation  for the  services  are  intended to  constitute
expenses of  administration  under any applicable  Federal or state  bankruptcy,
insolvency or other similar law.

                  As security  for the  performance  of the  obligations  of the
Company  under  this  Section,  the  Trustee  shall  have  a lien  prior  to the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of (or premium,  if any)
or interest on particular Securities or coupons.

                  The  provisions of this Section shall survive the  termination
of this Indenture.

                  SECTION  607.   Corporate   Trustee   Required;   Eligibility;
Conflicting  Interests.  There shall at all times be a Trustee  hereunder  which
shall be eligible to act as Trustee under TIA Section 310(a)(1) and shall have a
combined  capital  and  surplus  of at least  $50,000,000.  If such  corporation
publishes  reports  of  condition  at  least  annually,  pursuant  to law or the
requirements of Federal, state,  Territorial or District of Columbia supervising
or  examining  authority,  then for the purposes of this  Section,  the combined
capital  and  surplus  of such  corporation  shall be deemed to be its  combined
capital  and  surplus as set forth in its most  recent  report of  condition  so
published.  If at any time the Trustee  shall cease to be eligible in accordance
with the provisions of this Section,  it shall resign  immediately in the manner
and with the effect hereinafter specified in this Article.

                  SECTION  608.   Resignation   and  Removal;   Appointment   of
Successor.  (a) No resignation or removal of the Trustee and no appointment of a
successor  Trustee  pursuant to this Article  shall become  effective  until the
acceptance  of  appointment  by the  successor  Trustee in  accordance  with the
applicable requirements of Section 609.

                  (b) The  Trustee  may  resign at any time with  respect to the
Securities  of one or more  series  by  giving  written  notice  thereof  to the
Company.  If an instrument  of acceptance by a successor  Trustee shall not have
been  delivered to the Trustee within 30 days after the giving of such notice of
resignation,   the  resigning  Trustee  may  petition  any  court  of  competent
jurisdiction for the appointment of a successor Trustee.

                  (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee and to the
Company.

                  (d) If at any time:

                  (1) the Trustee  shall fail to comply with the  provisions  of
         TIA Section 310(b) after written request  therefor by the Company or by
         any Holder of a Security  who has been a bona fide Holder of a Security
         for at least six months, or

                                       33
<PAGE>

                  (2) the  Trustee  shall  cease to be  eligible  under  Section
         607(a) and shall fail to resign after written  request  therefor by the
         Company or by any Holder of a Security  who has been a bona fide Holder
         of a Security for at least six months, or

                  (3) the Trustee  shall become  incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property  shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove  the  Trustee  and  appoint  a  successor  Trustee  with  respect  to all
Securities,  or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others  similarly  situated,  petition any court of competent
jurisdiction  for the removal of the Trustee with respect to all  Securities and
the appointment of a successor Trustee or Trustees.

                  (e)  If  the  Trustee  shall  resign,  be  removed  or  become
incapable  of acting,  or if a vacancy  shall occur in the office of Trustee for
any reason with respect to the Securities of one or more series, the Company, by
or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or
Trustees  with  respect  to the  Securities  of that or those  series  (it being
understood that any such successor  Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall
be only one Trustee with respect to the  Securities of any  particular  series).
If,  within one year after such  resignation,  removal or  incapability,  or the
occurrence of such vacancy,  a successor  Trustee with respect to the Securities
of any  series  shall  be  appointed  by Act of the  Holders  of a  majority  in
principal  amount of the Outstanding  Securities of such series delivered to the
Company and the retiring  Trustee,  the  successor  Trustee so appointed  shall,
forthwith upon its acceptance of such appointment,  become the successor Trustee
with respect to the  Securities of such series and to that extent  supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the  Securities  of any series shall have been so appointed by the Company or
the Holders of Securities  and accepted  appointment  in the manner  hereinafter
provided  any Holder of a Security who has been a bona fide Holder of a Security
of such  series for at least six months may, on behalf of himself and all others
similarly  situated,  petition  any  court  of  competent  jurisdiction  for the
appointment of a successor Trustee with respect to Securities of such series.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee  with  respect to the  Securities  of any series and each
appointment of a successor  Trustee with respect to the Securities of any series
in the manner  provided for notices to the Holders of Securities in Section 106.
Each notice shall include the name of the successor  Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

                  SECTION 609.  Acceptance of Appointment  by Successor.  (a) In
case of the  appointment  hereunder  of a successor  Trustee with respect to all
Securities,  every such successor Trustee shall execute, acknowledge and deliver
to  the  Company  and to the  retiring  Trustee  an  instrument  accepting  such
appointment,  and thereupon the  resignation or removal of the retiring  Trustee
shall become effective and such successor Trustee, without any further act, deed
or  conveyance,  shall  become  vested with all the rights,  powers,  trusts and
duties  of the  retiring  Trustee;  but,  upon  request  of the  Company  or the
successor  Trustee,  such retiring  Trustee shall,  upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights,  powers  and trusts of the  retiring  Trustee,  and shall  duly  assign,
transfer  and deliver to such  successor  Trustee all property and money held by
such retiring  Trustee  hereunder,  subject  nevertheless  to its claim, if any,
provided for in Section 606.

                  (b)  In  case  of the  appointment  hereunder  of a  successor
Trustee with respect to the Securities of one or more (but not all) series,  the
Company,  the retiring  Trustee and each  successor  Trustee with respect to the
Securities  of one or  more  series  shall  execute  and  deliver  an  indenture
supplemental  hereto,  pursuant to Article Nine hereof,  wherein each  successor
Trustee  shall  accept  such  appointment  and  which  (1)  shall  contain  such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor  Trustee relates,  (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such

                                       34
<PAGE>
provisions  as shall be deemed  necessary  or  desirable to confirm that all the
rights,  powers,  trusts and duties of the retiring  Trustee with respect to the
Securities  of that or those  series as to which  the  retiring  Trustee  is not
retiring shall continue to be vested in the retiring Trustee,  and (3) shall add
to or change any of the  provisions  of this  Indenture as shall be necessary to
provide for or facilitate  the  administration  of the trusts  hereunder by more
than  one  Trustee,   it  being  understood  that  nothing  herein  or  in  such
supplemental  indenture shall  constitute such Trustees  co-trustees of the same
trust and that each such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder  administered by any other
such Trustee; and upon the execution and delivery of such supplemental indenture
the resignation or removal of the retiring Trustee shall become effective to the
extent  provided  therein and each such successor  Trustee,  without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring  Trustee with  respect to the  Securities  of that or
those series to which the appointment of such successor Trustee relates; but, on
request of the Company or any successor  Trustee,  such  retiring  Trustee shall
duly  assign,  transfer and deliver to such  successor  Trustee all property and
money held by such retiring Trustee  hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

                  (c) Upon request of any such  successor  Trustee,  the Company
shall execute any and all instruments  for more fully and certainly  vesting in,
and  confirming  to such  successor  Trustee all such rights,  powers and trusts
referred to in paragraph (a) or (b) of this Section, as the case may be.

                  (d) No successor  Trustee shall accept its appointment  unless
at the time of such  acceptance  such  successor  Trustee shall be qualified and
eligible under this Article.

                  SECTION 610. Merger,  Conversion,  Consolidation or Succession
to Business.  Any corporation  into which the Trustee may be merged or converted
or with which it may be  consolidated,  or any  corporation  resulting  from any
merger,  conversion or  consolidation  to which the Trustee shall be a party, or
any corporation  succeeding to all or  substantially  all of the corporate trust
business  of the  Trustee,  shall be the  successor  of the  Trustee  hereunder;
provided such corporation  shall be otherwise  qualified and eligible under this
Article,  without the execution or filing of any paper or any further act on the
part of any of the parties hereto.  In case any Securities or coupons shall have
been  authenticated,  but not  delivered,  by the  Trustee  then in office,  any
successor by merger,  conversion or consolidation to such authenticating Trustee
may  adopt  such  authentication  and  deliver  the  Securities  or  coupons  so
authenticated  with the same  effect as if such  successor  Trustee  had  itself
authenticated  such  Securities  or coupons.  In case any  Securities or coupons
shall  not  have  been  authenticated  by such  predecessor  Trustee,  any  such
successor  Trustee may authenticate  and deliver such Securities or coupons,  in
either its own name or that of its predecessor Trustee,  with the full force and
effect which this Indenture  provides for the certificate of  authentication  of
the Trustee.

                  SECTION 611. Appointment of Authentication  Agent. At any time
when any of the  Securities  remain  Outstanding,  the  Trustee  may  appoint an
Authenticating  Agent or Agents with respect to one or more series of Securities
which  shall be  authorized  to act on behalf  of the  Trustee  to  authenticate
Securities  of such series  issued upon  exchange,  registration  of transfer or
partial redemption or repayment thereof,  and Securities so authenticated  shall
be entitled to the benefits of this  Indenture and shall be valid and obligatory
for  all  purposes  as if  authenticated  by the  Trustee  hereunder.  Any  such
appointment  shall  be  evidenced  by  an  instrument  in  writing  signed  by a
Responsible Officer of the Trustee, a copy of which instrument shall be promptly
furnished to the Company.  Wherever  reference is made in this  Indenture to the
authentication  and  delivery  of  Securities  by the  Trustee or the  Trustee's
certificate  of  authentication,  such  reference  shall be  deemed  to  include
authentication and delivery on behalf of the Trustee by an Authenticating  Agent
and a  certificate  of  authentication  executed  on behalf of the Trustee by an
Authenticating  Agent.  Each  Authenticating  Agent shall be  acceptable  to the
Company and, except as may otherwise be provided  pursuant to Section 301, shall
at all  times be a bank or trust  company  or  corporation  organized  and doing
business and in good standing  under the laws of the United States of America or
of any State or the District of Columbia,  authorized  under such laws to act as
Authenticating  Agent,  having a combined  capital  and surplus of not less than
$50,000,000  and  subject  to  supervision  or  examination  by federal or state
authorities.  If such  Authenticating  Agent  publishes  reports of condition at
least annually, pursuant to law or the requirements of the aforesaid supervising
or  examining  authority,  then for the purposes of this  Section,  the combined
capital  and  surplus  of such  Authenticating  Agent  shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. In case at any time an

                                       35
<PAGE>

Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions of this Section,  such Authenticating  Agent shall resign immediately
in the manner and with the effect specified in this Section.

                  Any  corporation  into  which an  Authenticating  Agent may be
merged or converted  or with which it may be  consolidated,  or any  corporation
resulting  from  any  merger,   conversion  or   consolidation   to  which  such
Authenticating  Agent shall be a party,  or any  corporation  succeeding  to the
corporate agency or corporate trust business of an Authenticating  Agent,  shall
continue to be an  Authenticating  Agent,  provided  such  corporation  shall be
otherwise  eligible  under this Section,  without the execution or filing of any
paper or further act on the part of the Trustee or the Authenticating Agent.

                  An  Authenticating  Agent for any series of Securities  may at
any time resign by giving  written notice of resignation to the Trustee for such
series and to the Company.  The Trustee for any series of Securities  may at any
time terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination,  or in case at any time such
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions of this Section,  the Trustee for such series may appoint a successor
Authenticating  Agent  which shall be  acceptable  to the Company and shall give
notice of such  appointment  to all  Holders of  Securities  of the series  with
respect to which such Authenticating Agent will serve in the manner set forth in
Section  106.  Any  successor   Authenticating  Agent  upon  acceptance  of  its
appointment hereunder shall become vested with all the rights, powers and duties
of its  predecessor  hereunder,  with like effect as if  originally  named as an
Authenticating  Agent  herein.  No  successor   Authenticating  Agent  shall  be
appointed unless eligible under the provisions of this Section.

                  The Company  agrees to pay to each  Authenticating  Agent from
time to time reasonable  compensation including  reimbursement of its reasonable
expenses for its services under this Section.

                  If an  appointment  with respect to one or more series is made
pursuant  to this  Section,  the  Securities  of such  series may have  endorsed
thereon,   in  addition  to  or  in  lieu  of  the  Trustee's   certificate   of
authentication,  an alternate certificate of authentication substantially in the
following form:

                           This  is  one  of  the   Securities   of  the  series
                  designated   therein  referred  to  in  the   within-mentioned
                  Indenture.

any  Authenticating  Agent nor any Paying Agent nor any Security Registrar shall

         Company  is not  required  to file  information,  documents  or reports
         pursuant to either of such Sections, then it will file with the Trustee
         and the Commission, in accordance with rules and regulations prescribed
         from  time to time by the  Commission,  such of the  supplementary  and
         periodic  information,  documents  and  reports  which may be  required

         Commission.

                  SECTION 801.  Consolidations and Mergers of Company and Sales,
Leases and Conveyances Permitted Subject to Certain Conditions.  The Company may
consolidate  with,  or sell,  lease or convey  all or  substantially  all of its
assets to, or merge  with or into any other  corporation;  provided  that in any
such case, (i) either the Company

                                       37
<PAGE>
shall be the continuing  corporation,  or the successor  corporation  shall be a
corporation  organized  and  existing  under the laws of the United  States or a
State thereof and such successor  corporation shall expressly assume the due and
punctual  payment of the  principal  of (and  premium,  if any) and any interest
(including all Additional  Amounts, if any, payable pursuant to Section 1007) on
all of the  Securities,  according  to  their  tenor,  and the due and  punctual
performance  and  observance  of all of the  covenants  and  conditions  of this
Indenture to be performed by the Company by  supplemental  indenture,  complying
with Article Nine hereof, satisfactory to the Trustee, executed and delivered to
the Trustee by such corporation and (ii) immediately after giving effect to such
transaction  and treating any  indebtedness  which  becomes an obligation of the
Company or any  Subsidiary  as a result  thereof as having been  incurred by the
Company or such Subsidiary at the time of such transaction, no Event of Default,
and no event which,  after notice or the lapse of time, or both, would become an
Event of Default, shall have occurred and be continuing.

                  SECTION 802.  Rights and Duties of Successor  Corporation.  In
case of any such consolidation,  merger,  sale, lease or conveyance and upon any
such assumption by the successor  corporation,  such successor corporation shall
succeed to and be substituted for the Company, with the same effect as if it had
been  named  herein  as the  party  of  the  first  part,  and  the  predecessor
corporation,  except in the event of a lease,  shall be  relieved of any further
obligation under this Indenture and the Securities.  Such successor  corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of the  Company,  any or all of the  Securities  issuable  hereunder  which
theretofore  shall not have been  signed by the  Company  and  delivered  to the
Trustee;  and,  upon the order of such  successor  corporation,  instead  of the
Company,  and  subject  to all the terms,  conditions  and  limitations  in this
Indenture  prescribed,  the Trustee  shall  authenticate  and shall  deliver any
Securities which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication,  and any Securities which such
successor  corporation  thereafter shall cause to be signed and delivered to the
Trustee for that  purpose.  All the  Securities  so issued shall in all respects
have the same legal rank and  benefit  under this  Indenture  as the  Securities
theretofore or thereafter  issued in accordance with the terms of this Indenture
as though all of such  Securities  had been issued at the date of the  execution
hereof.

                  In case of any  such  consolidation,  merger,  sale,  lease or
conveyance,  such changes in phraseology  and form (but not in substance) may be
made in the Securities thereafter to be issued as may be appropriate.

                  SECTION 803. Officers' Certificate and Opinion of Counsel. Any
consolidation,  merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers'  Certificate
and an Opinion of Counsel  to the effect  that any such  consolidation,  merger,
sale, lease or conveyance, and the assumption of the Company's obligations under
this  Indenture by any successor  corporation,  complies with the  provisions of
this Article and that all conditions  precedent  herein provided for relating to
such transaction have been complied with.

                  SECTION  901.  Supplemental   Indentures  Without  Consent  of
Holders.  Without  the  consent of any Holders of  Securities  or  coupons,  the
Company, when authorized by or pursuant to a Board Resolution,  and the Trustee,
at any  time  and  from  time to time,  may  enter  into one or more  indentures
supplemental  hereto,  in  form  satisfactory  to the  Trustee,  for  any of the
following purposes:

                  (1) to  evidence  the  succession  of  another  Person  to the
         Company and the  assumption  by any such  successor of the covenants of
         the Company herein and in the Securities contained; or

                  (2) to add to the  covenants of the Company for the benefit of
         the Holders of all or any series of Securities  (and if such  covenants
         are to be for the  benefit  of less  than  all  series  of  Securities,
         stating that such covenants are expressly being included solely for the
         benefit  of such  series)  or to  surrender  any right or power  herein
         conferred upon the Company; or

                  (3) to add any additional Events of Default for the benefit of
         the Holders of all or any series of  Securities  (and if such Events of
         Default  are  to be  for  the  benefit  of  less  than  all  series  of
         Securities,  stating  that such Events of Default are  expressly  being
         included  solely for the benefit of such  series);  provided,  however,
         that  in  respect  of  any  such  additional  Events  of  Default  such
         supplemental  indenture  may provide for a  particular  period of grace
         after default  (which period may be shorter or longer than that allowed
         in the  case  of  other  defaults)  or  may  provide  for an  immediate
         enforcement  upon such default or may limit the  remedies  available to
         the Trustee  upon such default or may limit the right of the Holders of
         a majority in  aggregate  principal  amount of that or those  series of
         Securities  to which such  additional  Events of Default apply to waive
         such default; or

                  (4)  to add  to or  change  any  of  the  provisions  of  this
         Indenture to provide that Bearer  Securities  may be  registrable as to
         principal,  to change or eliminate any  restrictions  on the payment of
         principal of or any premium or interest on Bearer Securities, to permit
         Bearer  Securities to be issued in exchange for Registered  Securities,
         to  permit  Bearer  Securities  to be  issued in  exchange  for  Bearer
         Securities of other authorized denominations or to permit or facilitate
         the issuance of Securities in uncertificated form;  provided,  that any
         such action shall not adversely  affect the interests of the Holders of
         Securities  of  any  series  or any  related  coupons  in any  material
         respect; or

                  (5) to  change  or  eliminate  any of the  provisions  of this
         Indenture;  provided that any such change or  elimination  shall become
         effective  only when  there is no  Security  Outstanding  of any series
         created prior to the execution of such supplemental  indenture which is
         entitled to the benefit of such provision; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
         and any related coupons as permitted by Sections 201 and 301, including
         the provisions and procedures  relating to Securities  convertible into
         Common Shares or Preferred  Shares of the Company,  as the case may be;
         or

                  (8) to evidence and provide for the  acceptance of appointment
         hereunder by a successor  Trustee with respect to the Securities of one
         or more  series and to add to or change any of the  provisions  of this
         Indenture  as shall be  necessary  to  provide  for or  facilitate  the
         administration of the trusts hereunder by more than one Trustee; or

                  (9) to cure  any  ambiguity,  to  correct  or  supplement  any
         provision herein which may be defective or inconsistent  with any other
         provision  herein,  or to make any other  provisions  with  respect  to
         matters or questions  arising under this  Indenture  which shall not be
         inconsistent  with the  provisions  of this  Indenture;  provided  such
         provisions  shall not adversely  affect the interests of the Holders of
         Securities of any series or any related coupons in any material
         respect; or

                  (10) to supplement  any of the provisions of this Indenture to
         such  extent  as  shall  be  necessary  to  permit  or  facilitate  the
         defeasance  and  discharge  of any  series of  Securities  pursuant  to
         Sections  401,  1402 and 1403;  provided that any such action shall not
         adversely  affect the  interests of the Holders of  Securities  of such
         series and any related coupons or any other series of Securities in any
         material respect.

                  SECTION 902. Supplemental  Indentures with Consent of Holders.
With the consent of the Holders of not less than a majority in principal  amount
of all Outstanding Securities affected by such supplemental indenture, by Act of
said  Holders  delivered  to the  Company and the  Trustee,  the  Company,  when
authorized by or pursuant to a Board Resolution,  and the Trustee may enter into
an indenture  or  indentures  supplemental  hereto for the purpose of adding any
provisions to or changing in any manner or eliminating  any of the provisions of
this  Indenture  or of  modifying  in any manner  the  rights of the  Holders of
Securities and any related coupons under this Indenture; provided, however, that
no such supplemental  indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

                                       39
<PAGE>
                  (1)  change  the  Stated  Maturity  of  the  principal  of (or
         premium, if any, on) or any installment of principal of or interest on,
         any  Security;  or reduce the principal  amount  thereof or the rate or
         amount of interest thereon or any Additional Amounts payable in respect
         thereof,  or any premium payable upon the redemption thereof, or change
         any  obligation of the Company to pay  Additional  Amounts  pursuant to
         Section 1007 (except as contemplated by Section 801(i) and permitted by
         Section  901(1)),  or reduce the amount of the principal of an Original
         Issue  Discount   Security  that  would  be  due  and  payable  upon  a
         declaration of acceleration of the Maturity thereof pursuant to Section
         502 or the amount  thereof  provable in bankruptcy  pursuant to Section
         504, or  adversely  affect any right of  repayment at the option of the
         Holder of any Security,  or change any Place of Payment  where,  or the
         currency or currencies, currency unit or units or composite currency or
         currencies  in which,  any  Security  or any  premium  or the  interest
         thereon  is  payable,  or impair  the right to  institute  suit for the
         enforcement of any such payment on or after the Stated Maturity thereof
         (or,  in the case of  redemption  or  repayment  at the  option  of the
         Holder,  on or after the Redemption  Date or the Repayment Date, as the
         case may be), or

                  (2)  reduce  the   percentage  in  principal   amount  of  the
         Outstanding  Securities of any series,  the consent of whose Holders is
         required for any such supplemental  indenture,  or the consent of whose
         Holders is  required  for any waiver  with  respect to such  series (or
         compliance  with  certain  provisions  of  this  Indenture  or  certain
         defaults  hereunder  and  their  consequences)  provided  for  in  this
         Indenture,  or reduce the  requirements  of Section  1504 for quorum or
         voting, or

                  (3) modify any of the provisions of this Section,  Section 513
         or Section 1008,  except to increase the required  percentage to effect
         such  action  or to  provide  that  certain  other  provisions  of this
         Indenture  cannot be  modified  or waived  without  the  consent of the
         Holder of each Outstanding Security affected thereby.

                  It shall not be  necessary  for any Act of Holders  under this
Section to approve the particular form of any proposed  supplemental  indenture,
but it shall be sufficient if such Act shall approve the substance thereof.

                  A  supplemental  indenture  which  changes or  eliminates  any
covenant or other  provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities,  or which
modifies the rights of the Holders of  Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

                  SECTION  903.   Execution  of  Supplemental   Indentures.   In
executing,  or accepting  the  additional  trusts  created by, any  supplemental
indenture  permitted by this Article or the  modification  thereby of the trusts
created by this Indenture,  the Trustee shall be entitled to receive,  and shall
be fully  protected  in relying  upon,  an Opinion of Counsel  stating  that the
execution  of such  supplemental  indenture is  authorized  or permitted by this
Indenture.  The Trustee may, but shall not be obligated  to, enter into any such
supplemental  indenture  which  affects  the  Trustee's  own  rights,  duties or
immunities under this Indenture or otherwise.

                  SECTION  904.  Effect  of  Supplemental  Indentures.  Upon the
execution of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith and such supplemental indenture shall form a
part  of this  Indenture  for all  purposes;  and  every  Holder  of  Securities
theretofore  or  thereafter  authenticated  and  delivered  hereunder and of any
coupon appertaining thereto shall be bound thereby.

                  SECTION  905.  Conformity  with  Trust  Indenture  Act.  Every
supplemental  indenture  executed  pursuant to this Article shall conform to the
requirements of the Trust Indenture Act as then in effect.

                  SECTION  906.   Reference  in   Securities   to   Supplemental
Indentures.  Securities  of any series  authenticated  and  delivered  after the
execution of any supplemental indenture pursuant to this Article may, and shall,
if required by the Trustee,  bear a notation in form  approved by the Trustee as
to any matter provided for in such supplemental  indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in

                                       40
<PAGE>
the opinion of the Trustee and the Company,  to any such supplemental  indenture
may be prepared and executed by the Company and  authenticated  and delivered by
the Trustee in exchange for Outstanding Securities of such series.

                                   ARTICLE TEN

                                    COVENANTS

                  SECTION 1001. Payment of Principal,  Premium, if any, Interest
and Additional Amounts.  The Company covenants and agrees for the benefit of the
Holders of each series of Securities  that it will duly and  punctually  pay the
principal of (and premium,  if any) and interest on and any  Additional  Amounts
payable in respect of the Securities of that series in accordance with the terms
of such  series  of  Securities,  any  coupons  appertaining  thereto  and  this
Indenture.  Unless  otherwise  specified  as  contemplated  by Section  301 with
respect to any series of  Securities,  any  interest  due on and any  Additional
Amounts  payable in respect of Bearer  Securities on or before  Maturity,  other
than Additional  Amounts, if any, payable as provided in Section 1007 in respect
of principal of (or premium, if any, on) such a Security,  shall be payable only
upon  presentation  and  surrender  of the  several  coupons  for such  interest
installments as are evidenced thereby as they severally mature. Unless otherwise
specified  with respect to Securities of any series  pursuant to Section 301, at
the option of the Company, all payments of principal may be paid by check to the
registered  Holder of the Registered  Security or other person entitled  thereto
against surrender of such Security.

                  SECTION 1002.  Maintenance of Office or Agency.  If Securities
of a series are  issuable  only as  Registered  Securities,  the  Company  shall
maintain  in each Place of Payment  for any  series of  Securities  an office or
agency  where  Securities  of that series may be presented  or  surrendered  for
payment or conversion,  where  Securities of that series may be surrendered  for
registration  of transfer or exchange,  and where notices and demands to or upon
the Company in respect of the  Securities of that series and this  Indenture may
be served.  If  Securities  of a series are issuable as Bearer  Securities,  the
Company will maintain: (A) in the Borough of Manhattan, The City of New York, an
office or agency where any Registered Securities of that series may be presented
or  surrendered  for payment or conversion,  where any Registered  Securities of
that series may be surrendered for registration of transfer, where Securities of
that series may be  surrendered  for  exchange,  where notices and demands to or
upon the Company in respect of the  Securities of that series and this Indenture
may be served and where Bearer Securities of that series and related coupons may
be presented  or  surrendered  for payment or  conversion  in the  circumstances
described in the following  paragraph  (and not  otherwise);  (B) subject to any
laws or regulations  applicable  thereto,  in a Place of Payment for that series
which is located outside the United States, an office or agency where Securities
of that series and related  coupons may be presented and surrendered for payment
(including  payment of any  Additional  Amounts  payable on  Securities  of that
series pursuant to Section 1007) or conversion;  provided,  however, that if the
Securities  of that series are listed on the  Luxembourg  Stock  Exchange or any
other stock exchange  located  outside the United States and such stock exchange
shall so require, the Company will maintain a Paying Agent for the Securities of
that series in Luxembourg or any other required city located  outside the United
States,  as the case may be, so long as the Securities of that series are listed
on such exchange; and (C) subject to any laws or regulations applicable thereto,
in a Place of Payment  for that  series  located  outside  the United  States an
office  or  agency  where  any  Registered  Securities  of  that  series  may be
surrendered for registration of transfer, where Securities of that series may be
surrendered for exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this  Indenture may be served.  The
Company will give prompt written notice to the Trustee of the location,  and any
change in the  location,  of each  such  office  or  agency.  If at any time the
Company shall fail to maintain any such required  office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the  Corporate  Trust Office of the
Trustee,  except that Bearer  Securities of that series and the related  coupons
may  be  presented  and  surrendered  for  payment  (including  payment  of  any
Additional  Amounts  payable on Bearer  Securities  of that  series  pursuant to
Section 1007) or conversion at the offices  specified in the Security in London,
England,  and the Company hereby  appoints the same as its agent to receive such
respective  presentations,  surrenders,  notices  and  demands,  and the Company
hereby  appoints  the  Trustee  its  agent to  receive  all such  presentations,
surrenders, notices and demands.

                  Unless  otherwise  specified  with  respect to any  Securities
pursuant  to Section  301,  no payment of  principal,  premium or interest on or
Additional  Amounts in respect of Bearer  Securities shall be made at any office
or agency of the Company in the United  States or by check mailed to any address
in the United States or by transfer to an

                                       41
<PAGE>
account maintained with a bank located in the United States; provided,  however,
that, if the Securities of a series are payable in Dollars, payment of principal
of and any premium and interest on any Bearer Security (including any Additional
Amounts  payable on Securities of such series pursuant to Section 1007) shall be
made at the office of the Company's Paying Agent in the City of Boston,  if (but
only if)  payment  in  Dollars of the full  amount of such  principal,  premium,
interest or Additional  Amounts,  as the case may be, at all offices or agencies
outside  the  United  States  maintained  for such  purpose  by the  Company  in
accordance with this Indenture,  is illegal or effectively precluded by exchange
controls or other similar restrictions.

                  The Company may from time to time  designate one or more other
offices or agencies  where the Securities of one or more series may be presented
or  surrendered  for any or all of such  purposes,  and  may  from  time to time
rescind  such  designation;  provided,  however,  that  no such  designation  or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in  accordance  with the  requirements  set forth  above for
Securities of any series for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency. Unless otherwise specified with
respect to any  Securities  pursuant to Section 301 with  respect to a series of
Securities,  the Company hereby designates as a Place of Payment for each series
of  Securities  the office or agency of the  Company in the City of Boston,  and
initially  appoints the Trustee at its Corporate Trust Office as Paying Agent in
such  city and as its  agent to  receive  all  such  presentations,  surrenders,
notices and demands.

                  Unless  otherwise  specified  with  respect to any  Securities
pursuant to Section 302, if and so long as the  Securities of any series (i) are
denominated in a Foreign  Currency or (ii) may be payable in a Foreign  Currency
or so long as it is required under any other provision of this  Indenture,  then
the Company will maintain with respect to each such series of Securities,  or as
so required, at least one exchange rate agent.

                  SECTION  1003.  Money for  Securities  Payments  to Be Held in
Trust. If the Company shall at any time act as its own Paying Agent with respect
to any series of any  Securities and any related  coupons,  it will, by no later
than 11:00 am (Boston  time) on each due date of the  principal of (and premium,
if any),  or  interest  on or  Additional  Amounts  in  respect  of,  any of the
Securities  of that series,  segregate  and hold in trust for the benefit of the
Persons entitled  thereto a sum in the currency or currencies,  currency unit or
units or composite currency or currencies in which the Securities of such series
are  payable  (except as  otherwise  specified  pursuant  to Section 301 for the
Securities of such series) sufficient to pay the principal (and premium, if any)
or interest or Additional  Amounts so becoming due until such sums shall be paid
to such Persons or otherwise  disposed of as herein provided,  and will promptly
notify the Trustee of its action or failure so to act.

                  Whenever the Company  shall have one or more Paying Agents for
any series of Securities and any related coupons, it will, on or before each due
date of the  principal of (and  premium,  if any),  or interest on or Additional
Amounts in respect of, any  Securities  of that  series,  deposit  with a Paying
Agent a sum (in the currency or currencies,  currency unit or units or composite
currency or currencies described in the preceding  paragraph)  sufficient to pay
the  principal  (and  premium,  if any) or interest or  Additional  Amounts,  so
becoming  due,  such  sum to be held in trust  for the  benefit  of the  Persons
entitled  to such  principal,  premium or  interest  or  Additional  Amounts and
(unless such Paying Agent is the Trustee) the Company will  promptly  notify the
Trustee of its action or failure so to act.

                  The  Company  will  cause  each  Paying  Agent  other than the
Trustee to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee,  subject to the  provisions of this Section,
that such Paying Agent will

                  (1) hold all sums held by it for the payment of  principal  of
         (and  premium,  if any) or  interest  on  Securities  in trust  for the
         benefit of the Persons  entitled  thereto until such sums shall be paid
         to such Persons or otherwise disposed of as herein provided;

                  (2) give the Trustee  notice of any default by the Company (or
         any  other  obligor  upon the  Securities)  in the  making  of any such
         payment of principal (and premium, if any) or interest; and

                                       42
<PAGE>
                  (3) at any time during the  continuance  of any such  default,
         upon the written  request of the Trustee,  forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

                  The Company may at any time,  for the purpose of obtaining the
satisfaction  and discharge of this Indenture or for any other purpose,  pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying  Agent,  such sums to be held by the Trustee
upon the same  trusts as those upon which such sums were held by the  Company or
such Paying  Agent;  and,  upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further  liability  with respect to
such sums.

                  Except as otherwise  provided in the Securities of any series,
any money  deposited  with the Trustee or any Paying Agent,  or then held by the
Company,  in trust for the payment of the principal of (and premium,  if any) or
interest on, or any Additional Amounts in respect of, any Security of any series
and remaining  unclaimed  for two years after such  principal  (and premium,  if
any), interest or Additional Amounts has become due and payable shall be paid to
the  Company  upon  Company  Request or (if then held by the  Company)  shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an  unsecured  general  creditor,  look only to the  Company for payment of such
principal of (and premium,  if any) or interest on, or any Additional Amounts in
respect of, such Security,  without interest  thereon,  and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee  thereof,  shall thereupon cease;  provided,  however,
that the Trustee or such Paying  Agent,  before being  required to make any such
repayment,  may at the expense of the Company cause to be published  once, in an
Authorized Newspaper, notice that such money remains unclaimed and that, after a
date  specified  therein,  which shall not be less than 30 days from the date of
such  publication,  any unclaimed  balance of such money then  remaining will be
repaid to the Company.

                  SECTION 1004. Existence. Subject to Article Eight, the Company
will do or cause to be done all things  necessary  to preserve  and keep in full
force  and  effect  its  existence,   rights  (declaration  and  statutory)  and
franchises;  provided,  however,  that the  Company  shall  not be  required  to
preserve  any  right  or  franchise  if  the  Board  shall  determine  that  the
preservation  thereof is no longer  desirable  in the conduct of the business of
the Company.

                  SECTION 1005. Provision of Financial  Information.  Whether or
not the Company is subject to Section 13 or 15(d) of the Securities Exchange Act
of 1934,  as  amended,  the  Company  will,  to the extent  permitted  under the
Securities Exchange Act of 1934, as amended, file with the Commission the annual
reports, quarterly reports and other documents which the Company would have been
required to file with the  Commission  pursuant to such Section 13 or 15(d) (the
"Financial  Statements")  if the Company were so subject,  such  documents to be
filed with the  Commission on or prior to the  respective  dates (the  "Required
Filing  Dates") by which the  Company  would have been  required so to file such
documents if the Company were so subject.

                  The Company  will also in any event (x) within 15 days of each
Required  Filing Date (i)  transmit by mail to all  Holders,  as their names and
addresses appear in the Security  Register,  without cost to such Holders copies
of the annual  reports and  quarterly  reports which the Company would have been
required  to file with the  Commission  pursuant  to  Section 13 or 15(d) of the
Securities Exchange Act of 1934, as amended, if the Company were subject to such
Sections, and (ii) file with the Trustee copies of the annual reports, quarterly
reports and other  documents  which the Company would have been required to file
with the Commission  pursuant to Section 13 or 15(d) of the Securities  Exchange
Act of 1934, as amended, if the Company were subject to such Sections and (y) if
filing such documents by the Company with the Commission is not permitted  under
the Securities  Exchange Act of 1934, as amended,  promptly upon written request
and payment of the reasonable cost of duplication and delivery, supply copies of
such documents to any prospective Holder.

                  SECTION  1006.  Statement as to  Compliance.  The Company will
deliver to the  Trustee,  within 120 days after the end of each fiscal  year,  a
brief  certificate from the principal  executive  officer,  principal  financial
officer  or  principal  accounting  officer  as to his or her  knowledge  of the
Company's compliance with all conditions and covenants under this Indenture and,
in the event of any noncompliance,  specifying such noncompliance and the nature
and status thereof.  For purposes of this Section 1006, such compliance shall be
determined  without regard to any period of grace or requirement of notice under
this Indenture.
                                       43
<PAGE>
                  SECTION  1007.  Additional  Amounts.  If any  Securities  of a
series  provide for the payment of Additional  Amounts,  the Company will pay to
the Holder of any  Security  of such series or any coupon  appertaining  thereto
Additional  Amounts as may be specified as contemplated by Section 301. Whenever
in this  Indenture  there is  mentioned,  in any  context  except in the case of
Section  502(1),  the payment of the principal of or any premium or interest on,
or in respect of, any Security of any series or payment of any related coupon or
the net proceeds received on the sale or exchange of any Security of any series,
such  mention  shall be deemed to include  mention of the payment of  Additional
Amounts provided by the terms of such series established pursuant to Section 301
to the extent that,  in such context,  Additional  Amounts are, were or would be
payable in respect  thereof  pursuant to such terms and  express  mention of the
payment of Additional Amounts (if applicable) in any provisions hereof shall not
be construed as excluding  Additional  Amounts in those provisions  hereof where
such express mention is not made.

                  Except as otherwise  specified as contemplated by Section 301,
if the Securities of a series provide for the payment of Additional  Amounts, at
least 20 days  prior to the first  Interest  Payment  Date with  respect to that
series of Securities (or if the Securities of that series will not bear interest
prior to Maturity, the first day on which a payment of principal and any premium
is made),  and at least 10 days prior to each date of payment of  principal  and
any premium or interest if there has been any change with respect to the matters
set forth in the below-mentioned Officers' Certificate, the Company will furnish
the Trustee and the Company's  principal Paying Agent or Paying Agents, if other
than the Trustee, with an Officers' Certificate instructing the Trustee and such
Paying  Agent or Paying  Agents  whether  such  payment of  principal of and any
premium or interest on the Securities of that series shall be made to Holders of
Securities  of that  series or any  related  coupons  who are not United  States
persons without  withholding  for or on account of any tax,  assessment or other
governmental  charge  described  in the  Securities  of the series.  If any such
withholding shall be required,  then such Officers' Certificate shall specify by
country the  amount,  if any,  required to be withheld on such  payments to such
Holders of Securities of that series or related coupons and the Company will pay
to the Trustee or such Paying Agent the Additional Amounts required by the terms
of such  Securities.  In the event that the Trustee or any Paying Agent,  as the
case may be,  shall not so receive  the  above-mentioned  certificate,  then the
Trustee  or such  Paying  Agent  shall be  entitled  (i) to assume  that no such
withholding or deduction is required with respect to any payment of principal or
interest with respect to any Securities of a series or related  coupons until it
shall  have  received  a  certificate  advising  otherwise  and (ii) to make all
payments of principal and interest with respect to the Securities of a series or
related coupons without  withholding or deductions until otherwise advised.  The
Company covenants to indemnify the Trustee and any Paying Agent for, and to hold
them  harmless  against,  any loss,  liability  or expense  reasonably  incurred
without  negligence  or bad faith on their part arising out of or in  connection
with  actions  taken or omitted by any of them or in reliance  on any  Officers'
Certificate  furnished  pursuant to this Section or in reliance on the Company's
not furnishing such an Officers' Certificate.

                  SECTION  1008.  Waiver of Certain  Covenants.  The Company may
omit in any particular instance to comply with any term,  provision or condition
set  forth  in  Sections  1004 or 1005,  if  before  or after  the time for such
compliance  the  Holders  of at least a  majority  in  principal  amount  of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive  compliance with such covenant or
condition,  but no such  waiver  shall  extend to or  affect  such  covenant  or
condition except to the extent so expressly waived, and, until such waiver shall
become  effective,  the obligations of the Company and the duties of the Trustee
in respect of any such term,  provision or condition  shall remain in full force
and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

                  SECTION  1101.  Applicability  of Article.  Securities  of any
series which are redeemable  before their Stated Maturity shall be redeemable in
accordance  with their terms and (except as otherwise  specified as contemplated
by Section 301 for Securities of any series) in accordance with this Article.

                  SECTION  1102.  Election  to Redeem;  Notice to  Trustee.  The
election  of the  Company  to redeem any  Securities  shall be  evidenced  by or
pursuant to a Board Resolution. In case of any redemption at the election of the
Company of less than all of the Securities of any series,  the Company shall, at
least 45 days prior to the giving of the

                                       44
<PAGE>
notice  of  redemption  in  Section  1104  (unless  a  shorter  notice  shall be
satisfactory to the Trustee),  notify the Trustee of such Redemption Date and of
the principal amount of Securities of such series to be redeemed. In the case of
any redemption of Securities  prior to the expiration of any restriction on such
redemption  provided  in the  terms  of such  Securities  or  elsewhere  in this
Indenture,  the Company shall furnish the Trustee with an Officers'  Certificate
evidencing compliance with such restriction.

                  SECTION  1103.  Selection  by  Trustee  of  Securities  to  Be
Redeemed.  If less than all the  Securities of any series issued on the same day
with the same terms are to be redeemed, the particular Securities to be redeemed
shall be  selected  not more than 60 days  prior to the  Redemption  Date by the
Trustee, from the Outstanding Securities of such series issued on such date with
the same terms not  previously  called  for  redemption,  by such  method as the
Trustee shall deem fair and  appropriate and which may provide for the selection
for redemption of portions  (equal to the minimum  authorized  denomination  for
Securities  of that series or any integral  multiple  thereof) of the  principal
amount of  Securities of such series of a  denomination  larger than the minimum
authorized denomination for Securities of that series.

                  The Trustee shall promptly notify the Company and the Security
Registrar  (if other than  itself) in writing  of the  Securities  selected  for
redemption and, in the case of any Securities  selected for partial  redemption,
the principal amount thereof to be redeemed.

                  For  all  purposes  of  this  Indenture,  unless  the  context
otherwise  requires,  all  provisions  relating to the  redemption of Securities
shall  relate,  in the case of any Security  redeemed or to be redeemed  only in
part, to the portion of the principal  amount of such Security which has been or
is to be redeemed.

                  SECTION 1104. Notice of Redemption. Notice of redemption shall
be given in the manner  provided in Section 106 and as may be further  specified
in an indenture supplemental hereto, not less than 30 days nor more than 60 days
prior to the Redemption Date,  unless a shorter period is specified by the terms
of such series established pursuant to Section 301, to each Holder of Securities
to be redeemed, but failure to give such notice in the manner herein provided to
the Holder of any Security  designated  for redemption as a whole or in part, or
any defect in the notice to any such  Holder,  shall not affect the  validity of
the  proceedings  for the  redemption  of any other  such  Security  or  portion
thereof.

                  Any  notice  that  is  mailed  to the  Holders  of  Registered
Securities in the manner herein provided shall be conclusively  presumed to have
been duly given, whether or not such Holders receive such notice.

                  All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption  Price,  accrued interest to the Redemption
         Date  payable as  provided  in Section  1106,  if any,  and  Additional
         Amounts, if any,

                  (3) if less than all Outstanding  Securities of any series are
         to be  redeemed,  the  identification  (and,  in the  case  of  partial
         redemption,  the  principal  amount)  of  the  particular  Security  or
         Securities to be redeemed,

                  (4) in case any  Security is to be redeemed in part only,  the
         notice which relates to such Security shall state that on and after the
         Redemption  Date,  upon  surrender  of such  Security,  the holder will
         receive,  without  charge,  a new Security or  Securities of authorized
         denominations for the principal amount thereof remaining unredeemed,

                  (5) that on the  Redemption  Date  the  Redemption  Price  and
         accrued  interest to the Redemption Date payable as provided in Section
         1106, if any, will become due and payable upon each such  Security,  or
         the portion thereof,  to be redeemed and, if applicable,  that interest
         thereon shall cease to accrue on and after said date,

                                       45
<PAGE>
                  (6) the Place or  Places of  Payment  where  such  Securities,
         together in the case of Bearer Securities with all coupons appertaining
         thereto,  if  any,  maturing  after  the  Redemption  Date,  are  to be
         surrendered for payment of the Redemption  Price and accrued  interest,
         if any, or for conversion,

                  (7) that the  redemption is for a sinking fund, if such is the
         case,

                  (8) that unless  otherwise  specified in such  notice,  Bearer
         Securities of any series,  if any,  surrendered  for redemption must be
         accompanied by all coupons  maturing  subsequent to the Redemption Date
         or the amount of any such  missing  coupon or coupons  will be deducted
         from the Redemption Price, unless security or indemnity satisfactory to
         the  Company,  the  Trustee  for such  series and any  Paying  Agent is
         furnished,

                           (9) if  Bearer  Securities  of any  series  are to be
         redeemed  and any  Registered  Securities  of such series are not to be
         redeemed, and if such Bearer Securities may be exchanged for Registered
         Securities not subject to redemption on this  Redemption  Date pursuant
         to Section  305 or  otherwise,  the last  date,  as  determined  by the
         Company, on which such exchanges may be made,

                  (10) the CUSIP number of such Security, if any, and

                  (11) if applicable, that a Holder of Securities who desires to
         convert  Securities for redemption  must satisfy the  requirements  for
         conversion  contained in such Securities,  the then existing conversion
         price or rate,  and the date and time when the option to convert  shall
         expire.

                  Notice of redemption  of  Securities  to be redeemed  shall be
given by the Company or, at the  Company's  request,  by the Trustee in the name
and at the expense of the Company.

                  SECTION  1105.  Deposit of  Redemption  Price.  On or prior to
11:00 am (Boston time) on any  Redemption  Date,  the Company shall deposit with
the  Trustee  or with a Paying  Agent (or,  if the  Company is acting as its own
Paying  Agent,  which it may not do in the case of a sinking fund payment  under
Article  Twelve,  segregate  and hold in trust as provided  in Section  1003) an
amount  of  money  in the  currency  or  currencies,  currency  unit or units or
composite  currency or  currencies  in which the  Securities  of such series are
payable  (except  as  otherwise  specified  pursuant  to  Section  301  for  the
Securities  of  such  series)  sufficient  to  pay on the  Redemption  Date  the
Redemption  Price of, and  (except if the  Redemption  Date shall be an Interest
Payment Date) accrued  interest on, all the Securities or portions thereof which
are to be redeemed on that date.

                  SECTION 1106. Securities Payable on Redemption Date. Notice of
redemption  having been given as  aforesaid,  the  Securities  so to be redeemed
shall, on the Redemption  Date,  become due and payable at the Redemption  Price
therein  specified  in the  currency or  currencies,  currency  unit or units or
composite  currency or  currencies  in which the  Securities  of such series are
payable  (except  as  otherwise  specified  pursuant  to  Section  301  for  the
Securities  of such  series)  (together  with accrued  interest,  if any, to the
Redemption Date), and from and after such date (unless the Company shall default
in the payment of the Redemption  Price and accrued  interest)  such  Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons
for such  interest  appertaining  to any Bearer  Securities  so to be  redeemed,
except to the extent provided  below,  shall be void. Upon surrender of any such
Security  for  redemption  in  accordance  with said notice,  together  with all
coupons, if any,  appertaining  thereto maturing after the Redemption Date, such
Security  shall be paid by the Company at the  Redemption  Price,  together with
accrued  interest,  if any, to the  Redemption  Date;  provided,  however,  that
installments  of interest on Bearer  Securities  whose Stated  Maturity is on or
prior to the  Redemption  Date  shall be  payable  only at an  office  or agency
located outside the United States (except as otherwise provided in Section 1002)
and,  unless  otherwise  specified as  contemplated  by Section  301,  only upon
presentation  and surrender of coupons for such interest;  and provided  further
that, except as otherwise  provided with respect to Securities  convertible into
Common Shares or Preferred  Shares of the Company,  installments  of interest on
Registered  Securities  whose Stated  Maturity is on or prior to the  Redemption
Date  shall  be  payable  to the  Holders  of  such  Securities,  or one or more
Predecessor  Securities,  registered  as such at the  close of  business  on the
relevant  Record Dates  according to their terms and the  provisions  of Section
307.

                                       46
<PAGE>
                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant  coupons maturing after the Redemption Date, such
Security may be paid after  deducting from the Redemption  Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or  coupons  may be waived by the  Company  and the  Trustee  if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent  harmless.  If thereafter  the Holder of such Security
shall  surrender to the Trustee or any Paying  Agent any such missing  coupon in
respect of which a  deduction  shall have been made from the  Redemption  Price,
such  Holder  shall be entitled  to receive  the amount so  deducted;  provided,
however, that interest represented by coupons shall be payable only at an office
or agency  located  outside the United States  (except as otherwise  provided in
Section 1002) and,  unless  otherwise  specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

                   If any Security  called for  redemption  shall not be so paid
upon  surrender  thereof for  redemption,  the principal  (and premium,  if any)
shall,  until paid,  bear interest from the Redemption Date at the rate borne by
the Security.

                  SECTION  1107.  Securities  Redeemed in Part.  Any  Registered
Security  which is to be redeemed  only in part  (pursuant to the  provisions of
this Article or of Article  Twelve) shall be  surrendered  at a Place of Payment
therefor (with,  if the Company or the Trustee so requires,  due endorsement by,
or a written  instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or his attorney duly  authorized in
writing) and the Company shall execute and the Trustee  shall  authenticate  and
deliver to the Holder of such Security  without service charge a new Security or
Securities of the same series,  of any authorized  denomination  as requested by
such Holder in  aggregate  principal  amount  equal to and in  exchange  for the
unredeemed portion of the principal of the Security so surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

                  SECTION 1201. Applicability of Article. The provisions of this
Article shall be applicable to any sinking fund for the retirement of Securities
of a series  except as otherwise  specified as  contemplated  by Section 301 for
Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of  Securities  of any series is herein  referred  to as a  "mandatory
sinking fund payment", and any payment in excess of such minimum amount provided
for by the terms of such  Securities  of any series is herein  referred to as an
"optional sinking fund payment".  If provided for by the terms of any Securities
of any series,  the cash amount of any  mandatory  sinking  fund  payment may be
subject to  reduction  as provided in Section  1202.  Each  sinking fund payment
shall be applied to the  redemption  of Securities of any series as provided for
by the terms of Securities of such series.

                  SECTION  1202.  Satisfaction  of Sinking  Fund  Payments  with
Securities. The Company may, in satisfaction of all or any part of any mandatory
sinking fund payment with  respect to the  Securities  of a series,  (1) deliver
Outstanding  Securities  of such series  (other than any  previously  called for
redemption)  together in the case of any Bearer  Securities  of such series with
all unmatured coupons  appertaining thereto and (2) apply as a credit Securities
of such series  which have been  redeemed  either at the election of the Company
pursuant to the terms of such Securities or through the application of permitted
optional  sinking fund  payments  pursuant to the terms of such  Securities,  as
provided  for by the terms of such  Securities,  or which  have  otherwise  been
acquired by the Company;  provided that such  Securities so delivered or applied
as a credit have not been  previously  so  credited.  Such  Securities  shall be
received  and  credited  for  such  purpose  by the  Trustee  at the  applicable
Redemption Price specified in such Securities for redemption  through  operation
of the sinking fund and the amount of such mandatory  sinking fund payment shall
be reduced accordingly.

                  SECTION 1203.  Redemption of Securities  for Sinking Fund. Not
less than 60 days prior to each sinking fund payment date for  Securities of any
series,  the  Company  will  deliver  to the  Trustee an  Officers'  Certificate
specifying  the amount of the next  ensuing  mandatory  sinking fund payment for
that series pursuant to the terms of that

                                       47
<PAGE>
series, the portion thereof, if any, which is to be satisfied by payment of cash
in the currency or currencies,  currency unit or units or composite  currency or
currencies  in which the  Securities  of such  series  are  payable  (except  as
otherwise  specified  pursuant to Section 301 for the Securities of such series)
and the portion  thereof,  if any,  which is to be satisfied by  delivering  and
crediting  Securities of that series  pursuant to Section 1202, and the optional
amount,  if any, to be added in cash to the next ensuing  mandatory sinking fund
payment,  and will also deliver to the Trustee any Securities to be so delivered
and credited.  If such Officers' Certificate shall specify an optional amount to
be added in cash to the next ensuing mandatory sinking fund payment, the Company
shall thereupon be obligated to pay the amount therein specified.  Not less than
30 days before each such sinking fund payment date the Trustee  shall select the
Securities  to be redeemed  upon such  sinking  fund  payment date in the manner
specified in Section 1103 and cause notice of the redemption thereof to be given
in the name of and at the  expense  of the  Company in the  manner  provided  in
Section  1104.  Such  notice  having  been duly given,  the  redemption  of such
Securities  shall be made upon the terms and in the  manner  stated in  Sections
1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

                  SECTION   1301.   Applicability   of  Article.   Repayment  of
Securities of any series  before their Stated  Maturity at the option of Holders
thereof shall be made in accordance with the terms of such  Securities,  if any,
and  (except as  otherwise  specified  by the terms of such  series  established
pursuant to Section 301) in accordance with this Article.

                  SECTION  1302.  Repayment  of  Securities.  Securities  of any
series  subject to  repayment  in whole or in part at the option of the  Holders
thereof will,  unless  otherwise  provided in the terms of such  Securities,  be
repaid at a price equal to the principal amount thereof, together with interest,
if any,  thereon  accrued to the Repayment  Date specified in or pursuant to the
terms of such Securities.  The Company covenants that on or before the Repayment
Date it will deposit with the Trustee or with a Paying Agent (or, if the Company
is acting as its own Paying  Agent,  segregate  and hold in trust as provided in
Section 1003) an amount of money in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are  payable  (except as  otherwise  specified  pursuant  to Section 301 for the
Securities of such series)  sufficient to pay the principal  (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of,
and (except if the  Repayment  Date shall be an Interest  Payment  Date) accrued
interest on, all the Securities or portions  thereof,  as the case may be, to be
repaid on such date.

                  SECTION  1303.  Exercise of Option.  Securities  of any series
subject  to  repayment  at the option of the  Holders  thereof  will  contain an
"Option to Elect Repayment" form on the reverse of such Securities. In order for
any Security to be repaid at the option of the Holder,  the Trustee must receive
at the Place of Payment therefor  specified in the terms of such Security (or at
such other place or places of which the  Company  shall from time to time notify
the Holders of such  Securities) not earlier than 60 days nor later than 30 days
prior to the  Repayment  Date (1) the Security so providing  for such  repayment
together with the "Option to Elect  Repayment"  form on the reverse thereof duly
completed by the Holder or by the Holder's  attorney duly  authorized in writing
or (2) a telegram,  telex, facsimile transmission or a letter from a member of a
national securities exchange, or the National Association of Securities Dealers,
Inc.  ("NASD"),  or a  commercial  bank or trust  company in the  United  States
setting  forth the name of the Holder of the Security,  the principal  amount of
the  Security,  the  principal  amount of the  Security to be repaid,  the CUSIP
number,  if any,  or a  description  of the tenor and terms of the  Security,  a
statement that the option to elect  repayment is being  exercised  thereby and a
guarantee that the Security to be repaid,  together with the duly completed form
entitled  "Option to Elect  Repayment" on the reverse of the  Security,  will be
received by the Trustee not later than the fifth  Business Day after the date of
such telegram, telex, facsimile transmission or letter; provided,  however, that
such telegram,  telex,  facsimile transmission or letter shall only be effective
if such  Security  and form duly  completed  are received by the Trustee by such
fifth Business Day. If less than the entire principal amount of such Security is
to be repaid in accordance with the terms of such Security, the principal amount
of such Security to be repaid,  in increments  of the minimum  denomination  for
Securities of such series, and the denomination or denominations of the Security
or Securities to be issued to the Holder for the portion of the principal amount
of such Security  surrendered that is not to be repaid,  must be specified.  The
principal  amount of any security  providing  for repayment at the option of the
Holder

                                       48
<PAGE>
thereof  may not be repaid in part if,  following  such  repayment,  the  unpaid
principal  amount of such  Security  would be less than the  minimum  authorized
denomination  of Securities of the series of which such Security to be repaid is
a part.  Except  as  otherwise  may be  provided  by the  terms of any  Security
providing  for  repayment at the option of the Holder  thereof,  exercise of the
repayment  option  by the  Holder  shall be  irrevocable  unless  waived  by the
Company.

                  SECTION 1304. When Securities  Presented for Repayment  Become
Due and Payable.  If  Securities  of any series  providing  for repayment at the
option of the Holders  thereof shall have been  surrendered  as provided in this
Article and as provided  by or  pursuant to the terms of such  Securities,  such
Securities  or the  portions  thereof,  as the case may be, to be  repaid  shall
become due and payable and shall be paid by the  Company on the  Repayment  Date
therein  specified,  and on and after such  Repayment  Date  (unless the Company
shall  default in the payment of such  Securities on such  Repayment  Date) such
Securities shall, if the same were interest-bearing,  cease to bear interest and
the coupons for such  interest  appertaining  to any Bearer  Securities so to be
repaid,  except to the extent provided  below,  shall be void. Upon surrender of
any such  Security for repayment in accordance  with such  provisions,  together
with all coupons,  if any,  appertaining  thereto  maturing  after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Company,  together  with  accrued  interest,  if  any,  to the  Repayment  Date;
provided,  however,  that coupons  whose  Stated  Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located  outside the
United  States  (except  as  otherwise  provided  in Section  1002) and,  unless
otherwise  specified  pursuant  to  Section  301,  only  upon  presentation  and
surrender of such coupons;  and provided further that, in the case of Registered
Securities,  installments  of interest,  if any, whose Stated  Maturity is on or
prior to the  Repayment  Date shall be payable  (but without  interest  thereon,
unless the Company shall default in the payment  thereof) to the Holders of such
Securities,  or one or more  Predecessor  Securities,  registered as such at the
close of business on the relevant  Record Dates according to their terms and the
provisions of Section 307.

                  If any Bearer Security  surrendered for repayment shall not be
accompanied by all appurtenant  coupons  maturing after the Repayment Date, such
Security  may be paid  after  deducting  from the  amount  payable  therefor  as
provided in Section  1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may  require  to save each of them and any  Paying  Agent  harmless.  If
thereafter  the Holder of such  Security  shall  surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction  shall have
been made as provided in the preceding  sentence,  such Holder shall be entitled
to receive the amount so deducted;  provided, however, that interest represented
by coupons  shall be payable  only at an office or agency  located  outside  the
United  States  (except  as  otherwise  provided  in Section  1002) and,  unless
otherwise  specified as contemplated by Section 301, only upon  presentation and
surrender of those coupons.

                  If the  principal  amount  of  any  Security  surrendered  for
repayment shall not be so repaid upon surrender  thereof,  such principal amount
(together with interest,  if any, thereon accrued to such Repayment Date) shall,
until paid,  bear interest  from the  Repayment  Date at the rate of interest or
Yield to Maturity (in the case of Original Issue Discount  Securities) set forth
in such Security.

                  SECTION 1305. Securities Repaid in Part. Upon surrender of any
Registered  Security  which is to be  repaid in part  only,  the  Company  shall
execute and the  Trustee  shall  authenticate  and deliver to the Holder of such
Security,  without  service  charge  and at the  expense of the  Company,  a new
Registered  Security  or  Securities  of the  same  series,  of  any  authorized
denomination  specified by the Holder, in an aggregate principal amount equal to
and in exchange for the portion of the principal of such Security so surrendered
which is not to be repaid.


                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

                  SECTION 1401.  Applicability  of Article;  Company's Option to
Effect Defeasance or Covenant Defeasance. If, pursuant to Section 301, provision
is made for either or both of (a)  defeasance  of the  Securities of or within a
series under  Section 1402 or (b) covenant  defeasance  of the  Securities of or
within a series under Section 1403,

                                       49
<PAGE>
then the  provisions of such Section or Sections,  as the case may be,  together
with the other  provisions of this Article (with such  modifications  thereto as
may be specified pursuant to Section 301 with respect to any Securities),  shall
be applicable to such Securities and any coupons  appertaining  thereto, and the
Company may at its option by Board Resolution, at any time, with respect to such
Securities and any coupons appertaining thereto,  elect to have Section 1402 (if
applicable)  or Section  1403 (if  applicable)  be  applied to such  Outstanding
Securities  and any  coupons  appertaining  thereto  upon  compliance  with  the
conditions set forth below in this Article.

                  SECTION 1402.  Defeasance  and  Discharge.  Upon the Company's
exercise of the above  option  applicable  to this  Section  with respect to any
Securities  of or  within a  series,  the  Company  shall be deemed to have been
discharged from its obligations with respect to such Outstanding  Securities and
any coupons appertaining thereto on the date the conditions set forth in Section
1404  are  satisfied  (hereinafter,   "defeasance").   For  this  purpose,  such
defeasance  means that the Company  shall be deemed to have paid and  discharged
the entire  indebtedness  represented  by such  Outstanding  Securities  and any
coupons   appertaining   thereto,   which  shall  thereafter  be  deemed  to  be
"Outstanding"  only for the purposes of Section  1405 and the other  Sections of
this Indenture  referred to in clauses (A) and (B) below,  and to have satisfied
all of its other obligations under such Securities and any coupons  appertaining
thereto  and  this  Indenture   insofar  as  such  Securities  and  any  coupons
appertaining  thereto  are  concerned  (and the  Trustee,  at the expense of the
Company,  shall execute proper instruments  acknowledging the same),  except for
the  following  which shall  survive  until  otherwise  terminated or discharged
hereunder:  (A) the  rights of Holders of such  Outstanding  Securities  and any
coupons appertaining thereto to receive, solely from the trust fund described in
Section 1404 and as more fully set forth in such Section, payments in respect of
the principal of (and premium, if any) and interest,  if any, on such Securities
and any  coupons  appertaining  thereto  when  such  payments  are due,  (B) the
Company's  obligations  with respect to such Securities under Sections 305, 306,
1002 and 1003 and with respect to the payment of Additional  Amounts, if any, on
such Securities as contemplated by Section 1007, (C) the rights, powers, trusts,
duties and  immunities of the Trustee  hereunder and (D) this Article  Fourteen.
Subject to compliance with this Article  Fourteen,  the Company may exercise its
option under this Section notwithstanding the prior exercise of its option under
Section  1403 with  respect  to such  Securities  and any  coupons  appertaining
thereto.

                  SECTION 1403. Covenant Defeasance. Upon the Company's exercise
of the above option applicable to this Section with respect to any Securities of
or within a series,  the Company  shall be released from its  obligations  under
Sections  1004  and  1005  and,  if  specified  pursuant  to  Section  301,  its
obligations  under  any  other  covenant,   with  respect  to  such  Outstanding
Securities  and any  coupons  appertaining  thereto  on and  after  the date the
conditions  set forth in  Section  1404 are  satisfied  (hereinafter,  "covenant
defeasance"),  and such  Securities and any coupons  appertaining  thereto shall
thereafter be deemed to be not  "Outstanding" for the purposes of any direction,
waiver,  consent or declaration or Act of Holders (and the  consequences  of any
thereof) in connection with Sections 1004 and 1005 or such other  covenant,  but
shall continue to be deemed "Outstanding" for all other purposes hereunder.  For
this  purpose,  such  covenant  defeasance  means  that,  with  respect  to such
Outstanding  Securities and any coupons  appertaining  thereto,  the Company may
omit to  comply  with and  shall  have no  liability  in  respect  of any  term,
condition or  limitation  set forth in any such Section or such other  covenant,
whether directly or indirectly,  by reason of any reference  elsewhere herein to
any such  Section or such other  covenant or by reason of  reference in any such
Section or such other  covenant  to any other  provision  herein or in any other
document and such omission to comply shall not  constitute a default or an Event

         Sections 501(6) and 501(7) are concerned, at any time during the period
         ending  on the  91st  day  after  the date of such  deposit  (it  being
         understood that this condition shall not be deemed  satisfied until the
         expiration of such period).

         stating  that (i) the  Company  has  received  from,  or there has been

         applicable  Federal  income tax law, in either case to the effect that,
         and based thereon such opinion shall confirm that,  the Holders of such
         Outstanding  Securities and any coupons  appertaining  thereto will not
         recognize  income,  gain or loss for Federal  income tax  purposes as a
         result of such  defeasance and will be subject to Federal income tax on
         the same  amounts,  in the same  manner  and at the same times as would
         have been the case if such defeasance had not occurred.

                           (e) In the case of an election  under  Section  1403,
         the Company  shall have  delivered to the Trustee an Opinion of Counsel
         to the effect that the Holders of such  Outstanding  Securities and any
         coupons  appertaining  thereto will not recognize income,  gain or loss
         for Federal income tax purposes as a result of such covenant defeasance
         and will be subject to Federal  income tax on the same amounts,  in the
         same  manner  and at the same times as would have been the case if such
         covenant defeasance had not occurred.

         covenant  defeasance  under Section 1403 (as the case may be) have been
         complied  with and an Opinion of Counsel to the effect  that either (i)
         as a result  of a  deposit  pursuant  to  subsection  (a) above and the
         related  exercise of the Company's option under Section 1402 or Section
         1403 (as the  case may be),  registration  is not  required  under  the
         Investment  Company  Act of 1940,  as  amended,  by the  Company,  with
         respect to the trust funds  representing such deposit or by the Trustee
         for such trust funds or (ii) all necessary registrations under said Act
         have been effected.

         Section,  such defeasance or covenant  defeasance  shall be effected in
         compliance  with any  additional  or  substitute  terms,  conditions or
         limitations which may be imposed on the Company in connection therewith
         pursuant to Section 301.

                  SECTION 1405. Deposited Money and Government Obligations to Be
Held in Trust; Other Miscellaneous Provisions.  Subject to the provisions of the
last paragraph of Section 1003, all money and Government  Obligations  (or other
property as may be provided  pursuant to Section  301)  (including  the proceeds
thereof) deposited with the Trustee (or other qualifying  trustee,  collectively
for purposes of this Section 1405,  the  "Trustee")  pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee,  in  accordance  with
the provisions of such Securities and any coupons  appertaining thereto and this
Indenture,  to  the  payment,  either  directly  or  through  any  Paying  Agent
(including  the  Company  acting as its own  Paying  Agent) as the  Trustee  may
determine,  to the  Holders  of such  Securities  and any  coupons  appertaining
thereto of all sums due and to become due thereon in respect of  principal  (and
premium,  if any) and interest and  Additional  Amounts,  if any, but such money
need not be segregated from other funds except to the extent required by law.

                  Unless  otherwise  specified  with  respect  to  any  Security
pursuant to Section 301, if, after a deposit  referred to in Section 1404(a) has
been made,  (a) the Holder of a Security  in respect of which such  deposit  was
made is  entitled  to, and does,  elect  pursuant to Section 301 or the terms of
such Security to receive  payment in a currency or currency unit other than that
in which the  deposit  pursuant  to Section  1404(a) has been made in respect of
such  Security,  or (b) a Conversion  Event occurs in respect of the currency or
currency  unit in which the deposit  pursuant to Section  1404(a) has been made,
the  indebtedness  represented  by such  Security  and any coupons  appertaining
thereto  shall  be  deemed  to have  been,  and will be,  fully  discharged  and
satisfied  through the payment of the  principal of (and premium,  if any),  and
interest,  if any, on such  Security as the same becomes due out of the proceeds
yielded by converting  (from time to time as specified  below in the case of any
such  election)  the  amount or other  property  deposited  in  respect  of such
Security  into the  currency or  currency  unit in which such  Security  becomes
payable as a result of such election or Conversion Event based on the applicable
market  exchange rate for such currency or currency unit in effect on the second
Business Day prior to each payment  date,  in the case of such an election,  or,
the applicable market exchange rate in effect for such currency or currency unit
(as nearly as feasible), in the case of such Conversion Event.

                  The Company shall pay and  indemnify  the Trustee  against any
tax,  fee  or  other  charge  imposed  on or  assessed  against  the  Government
Obligations  deposited  pursuant to Section 1404 or the  principal  and interest
received in respect  thereof  other than any such tax, fee or other charge which
by law is for the account of the Holders of such Outstanding  Securities and any
coupons appertaining thereto.

                  Anything in this Article to the contrary notwithstanding,  the
Trustee  shall  deliver  or pay to the  Company  from time to time upon  Company
Request any money or Government  Obligations (or other property and any proceeds
therefrom)  held by it as  provided in Section  1404 which,  in the opinion of a
nationally  recognized  firm of independent  public  accountants  expressed in a
written  certification  thereof  delivered to the Trustee,  are in excess of the
amount  thereof  which  would  then be  required  to be  deposited  to  effect a
defeasance  or covenant  defeasance,  as  applicable,  in  accordance  with this
Article.

proposed to be taken at the  meeting,  and the  Trustee  shall not have made the

meeting for such purposes by giving notice thereof as provided in subsection (a)

resolution  presented to a meeting or adjourned meeting duly reconvened at which
a quorum is present as aforesaid may be adopted by the  affirmative  vote of the
Holders of a majority in principal amount of the Outstanding  Securities of that
series;  provided,  however,  that,  except as limited by the proviso to Section
902,  any  resolution  with  respect  to  any  request,  demand,  authorization,

                  Notwithstanding the foregoing provisions of this Section 1504,
if any action is to be taken at a meeting of Holders of Securities of any series
with respect to any request, demand, authorization,  direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified  percentage  in  principal  amount of all
Outstanding  Securities  affected thereby,  or of the Holders of such series and

                  (i) there  shall be no  minimum  quorum  requirement  for such
         meeting; and

                  (ii) the  principal  amount of the  Outstanding  Securities of
         such series that vote in favor of such request, demand,  authorization,
         direction,  notice, consent, waiver or other action shall be taken into
         account in  determining  whether such request,  demand,  authorization,
         direction, notice, consent, waiver or other action has been made, given
         or taken under this Indenture.

                  SECTION  1505.  Determination  of Voting  Rights;  Conduct and
Adjournment of Meetings.  (a)  Notwithstanding any provisions of this Indenture,
the Trustee may make such  reasonable  regulations  as it may deem advisable for
any  meeting  of  Holders  of  Securities  of a series in regard to proof of the
holding of  Securities of such series and of the  appointment  of proxies and in
regard to the appointment and duties of inspectors of votes,  the submission and
examination  of proxies,  certificates  and other evidence of the right to vote,
and such other  matters  concerning  the conduct of the meeting as it shall deem
appropriate.  Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section 104
and the  appointment  of any proxy  shall be proved in the manner  specified  in
Section  104 or by  having  the  signature  of the  Person  executing  the proxy
witnessed or  guaranteed  by any trust  company,  bank or banker  authorized  by
Section 104 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies,  regular on their face, may
be presumed  valid and genuine  without  the proof  specified  in Section 104 or
other proof.

                  (b) The Trustee shall,  by an instrument in writing  appoint a
temporary chairman of the meeting,  unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case  may be,  shall in like  manner  appoint  a  temporary  chairman.  A
permanent chairman and a permanent  secretary of the meeting shall be elected by
vote of the  Persons  entitled  to vote a majority  in  principal  amount of the
Outstanding Securities of such series represented at the meeting.

                  (c) At any meeting each Holder of a Security of such series or
proxy  shall be entitled  to one vote for each  $1,000  principal  amount of the
Outstanding  Securities  of such series held or  represented  by him;  provided,
however,  that no vote shall be cast or counted at any meeting in respect of any
Security  challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding.  The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

                  (d) Any  meeting of Holders of  Securities  of any series duly
called  pursuant to Section  1502 at which a quorum is present may be  adjourned
from time to time by Persons  entitled to vote a majority in principal amount of
the Outstanding  Securities of such series  represented at the meeting,  and the
meeting may be held as so adjourned without further notice.

                  SECTION 1506. Counting Votes and Recording Action of Meetings.
The vote upon any  resolution  submitted to any meeting of Holders of Securities
of any series  shall be by  written  ballots on which  shall be  subscribed  the
signatures   of  the  Holders  of   Securities   of  such  series  or  of  their
representatives  by proxy and the  principal  amounts and serial  numbers of the
Outstanding Securities of such series held or represented by them. The permanent
chairman of the meeting  shall  appoint two  inspectors of votes who shall count
all votes cast at the meeting for or against any  resolution  and who shall make
and file with the secretary of the meeting  their  verified  written  reports in
duplicate of all votes cast at the meeting. A record, at least in duplicate,  of
the  proceedings of each meeting of Holders of Securities of any Series shall be
prepared  by the  secretary  of the  meeting and there shall be attached to said
record the  original  reports of the  inspectors  of votes on any vote by ballot
taken  thereat and  affidavits  by one or more persons  having  knowledge of the
fact,  setting  forth a copy of the notice of the meeting and showing  that said
notice was given as

                                       54
<PAGE>
provided in Section 1502 and, if  applicable,  Section 1504.  Each copy shall be
signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one such copy shall be  delivered  to the Company and another to
the Trustee to be preserved by the Trustee,  the latter to have attached thereto
the ballots  voted at the meeting.  Any record so signed and  verified  shall be
conclusive evidence of the matters therein stated.

                  This Indenture may be executed in any number of  counterparts,
each of which when so executed  shall be deemed to be an original,  but all such
counterparts shall together constitute but one and the same Indenture.

                  IN WITNESS  WHEREOF,  the  parties  hereto  have  caused  this
Indenture  to be duly  executed,  and  their  respective  corporate  seals to be
hereunto affixed and attested, all as of the day and year first above written.

Business Day immediately  following such LIBOR Determination Date, which appears
on Telerate Page 3750 as of approximately 11:00 a.m., London time, on such LIBOR

representative for a single  transaction in such market at such time;  provided,
however,  that if the banks  selected  as  aforesaid  by the Rate  Agent are not

U.S. Dollars are transacted in the London interbank market.

         "Make-Whole  Amount" means, in connection with any optional  redemption
or  accelerated  payment of any Note,  the excess,  if any, of (i) the aggregate
present value as of the date of such  redemption or accelerated  payment of each
dollar of principal being redeemed or paid and the amount of interest (exclusive
of interest accrued to the date of redemption or accelerated payment) that would
have been payable in respect of such dollar if such  redemption  or  accelerated
payment had not been made,  determined by  discounting,  on a semiannual  basis,
such principal and interest at the  Reinvestment  Rate  (determined on the third
Business  Day  preceding  the  date  such  notice  of  redemption  is  given  or
declaration of  acceleration  is made) from the  respective  dates on which such
principal and interest would have been payable if such redemption or accelerated
payment had not been made, over (ii) the aggregate principal amount of the Notes
being  redeemed or paid.  For purposes of this  Supplemental  Indenture  and the
Notes, references in the Indenture to the payment of the principal (and premium,

Make-Whole Amount, if any, due upon redemption with respect to the Notes.

"Treasury  Constant  Maturities" for the maturity (rounded to the nearest month)
corresponding  to the remaining life to maturity,  as of the payment date of the
principal  being  redeemed or paid. If no maturity  exactly  corresponds to such
maturity,  yields for the two published maturities most closely corresponding to
such maturity shall be calculated pursuant to the immediately preceding sentence
and the Reinvestment Rate shall be interpolated or extrapolated from such yields
on a  straight-line  basis,  rounding  in each of such  relevant  periods to the

recent  Statistical  Release published prior to the date of determination of the

selected by the Company to act as Remarketing Underwriter.

                               TERMS OF THE NOTES

         Section 201. Pursuant to Section 301 of the Indenture,  the Notes shall
have the following terms and conditions:

         (a) Title; Limitation on Aggregate Principal Amount. The Notes shall be
known as the Company's $200,000,000 Remarketed Reset Notes due July 9, 2007. The
Notes will be limited to an aggregate principal amount of $200,000,000.

         (b) Principal Repayment;  Currency. The stated maturity of the Notes is
July 9, 2007, provided, however, the Notes may be earlier redeemed at the option
of the Company as provided in paragraph  (d) below.  The  principal of each Note
payable on the maturity  date shall be paid against  presentation  and surrender
thereof at the corporate trust office of the Trustee,  located  initially at Two
International  Place,  Boston,  Massachusetts 02110, in such coin or currency of
the United  States of America as at the time of payment is legal  tender for the
payment of public or private debts. The Company will not pay Additional  Amounts
(as defined in the Indenture) on the Notes.

         (c) Interest  Payments.  During the Initial Spread Period, the interest
rate on the Notes  will be reset on each  Interest  Reset  Date,  and will equal
LIBOR plus the Initial  Spread.  The Initial  Spread is .45%.  After the Initial
Spread  Period,  unless  notice of  redemption  of the Notes as a whole has been
given, the duration,  redemption dates,  redemption type,  redemption prices (if
applicable),  Commencement  Date,  Interest  Payment Date and interest rate mode
will be agreed to by the Company and the  Remarketing  Underwriter by 3:00 p.m.,
New York City time, on each applicable Duration/Mode  Determination Date and the
Spread will be agreed to by the Company and the Remarketing  Underwriter by 3:00
p.m.,  New York City  time,  on the  corresponding  Spread  Determination  Date.
Interest on the Notes during each Subsequent Spread Period shall be payable,  as
applicable,  either (i) at a floating  interest  rate (such  Notes  being in the
"Floating Rate Mode", and such interest rate being a "Floating Rate") or (ii) at
a fixed  interest  rate  (such  Notes  being in the  "Fixed  Rate Mode" and such
interest  rate  being a  "Fixed  Rate"),  in  each  case  as  determined  by the
Remarketing  Underwriter  and  the  Company  in  accordance  with a  Remarketing
Agreement between the Remarketing  Underwriter and the Company (the "Remarketing
Agreement").

         After  the  Initial  Spread  Period,  the  Spread  applicable  to  each
Subsequent   Spread  Period  will  be  determined  on  each  subsequent   Spread
Determination Date which precedes the beginning of the corresponding  Subsequent
Spread Period, pursuant to agreement between the Company

                                        7

<PAGE>



and the Remarketing  Underwriter  (except as otherwise  provided below), and the
interest rate mode used for each Subsequent Spread Period may be a Floating Rate
Mode or a Fixed Rate Mode, at the discretion of the Company and the  Remarketing
Underwriter.  If the Company and the Remarketing Underwriter are unable to agree
on the Spread for any Subsequent Spread Period, (1) the Subsequent Spread Period
will be one year, (2) the Notes will be reset to the Floating Rate Mode, (3) the
Spread for such  Subsequent  Spread Period will be the Alternate  Spread and (4)
the Notes will be redeemable at the option of the Company,  in whole or in part,
upon at least  five  Business  Days'  notice  given by no later  than the  fifth
Business Day after the relevant Spread Determination Date, at a redemption price
equal to 100% of the principal amount thereof, together with accrued interest to
the  redemption  date,  except that the Notes may not be  redeemed  prior to the
Tender  Date or  later  than the last  day of such  one-year  Subsequent  Spread
Period. During the Initial Spread Period,  interest on the Notes will be payable
in Dollars  quarterly in arrears on October 9, 1997,  January 9, 1998,  April 9,
1998 and  July 9,  1998  (or,  if not a  Business  Day,  on the next  succeeding
Business Day except as described  herein).  After the Initial Spread Period, (i)
if the  Notes are in the  Floating  Rate  Mode,  interest  on the Notes  will be
payable,   unless   otherwise   specified   on  the   applicable   Duration/Mode
Determination Date,  quarterly in arrears on each January 9, April 9, July 9 and
October 9, during the applicable  Subsequent Spread Period, or (ii) if the Notes
are in the Fixed  Rate  Mode,  interest  on the Notes  will be  payable,  unless
otherwise  specified  on  the  applicable   Duration/Mode   Determination  Date,
semiannually  in  arrears  on  each  January  9 and  July  9  beginning  on  the
Commencement  Date and for the  duration  of the  applicable  Subsequent  Spread
Period. Interest on the Notes is payable to the persons in whose names the Notes
are  registered  at the close of  business  on the  applicable  Record Date next
preceding the applicable Interest Payment Date.

         Interest  on the Notes will  accrue from and  including  each  Interest
Payment Date (or in the case of the Initial Quarterly  Period,  July 9, 1997) to
but excluding the next succeeding Interest Payment Date or maturity date, as the
case may be. The Initial  Quarterly Period will be the period from and including
July 9, 1997 to but excluding the first Interest  Payment Date (October 9, 1997)
(the "Initial Quarterly Period").  Thereafter,  each Quarterly Period during the
Initial Spread Period or any Subsequent Spread Period will be from and including
the most recent  Interest  Payment  Date to which  interest has been paid to but
excluding the next Interest Payment Date.

         Payment of  interest on the Notes shall be made by the Trustee to or at
the direction of The  Depository  Trust Company or its nominee,  Cede & Co., who
will in turn immediately credit the account of the Remarketing Underwriter.

         If any Interest Payment Date (other than at maturity), redemption date,
Interest Reset Date,  Duration/Mode  Determination  Date,  Spread  Determination
Date,  Commencement  Date or Tender Date would  otherwise be a day that is not a
Business Day, such Interest Payment Date,  redemption date, Interest Reset Date,
Duration/Mode  Determination Date, Spread Determination Date,  Commencement Date
or Tender Date will be postponed to the next  succeeding  day that is a Business
Day, except that if such Business Day is in the next succeeding  calendar month,
such Interest Payment Date,  redemption date, Interest Reset Date,  Commencement
Date or Tender Date shall be the next preceding Business Day. If the maturity


                                        8

<PAGE>



date for the  Notes  falls  on a day that is not a  Business  Day,  the  related
payment of principal and interest will be made on the next  succeeding  Business
Day as if it were made on the date such  payment was due,  and no interest  will
accrue on the  amounts so payable  for the period for the period  from and after
such dates.

         If the  Notes are in the  Floating  Rate  Mode,  such  Notes  will bear
interest at a rate per annum (computed on the basis of the actual number of days
elapsed over a 360-day year) equal to LIBOR for the applicable  Quarterly Period
plus the  applicable  Spread,  as agreed to by the Company  and the  Remarketing
Underwriter, and such interest rate will be reset quarterly. If the Notes are in
the Fixed Rate Mode,  interest will equal the applicable Spread, as agreed to by
the Company and the Remarketing Underwriter,  plus the applicable Treasury rate,
computed on the basis of a 360-day year of twelve 30-day months. Interest in the
Fixed Rate Mode will accrue from and including each Interest Payment Date to but
excluding the next  succeeding  Interest  Payment Date or maturity  date, as the
case may be. If any Interest  Payment Date or any  redemption  date in the Fixed
Rate Mode falls on a day that is not a Business Day (in either case,  other than
any Interest Payment Date or redemption date that falls on a Commencement  Date,
in which case such Commencement Date will be postponed to the next day that is a
Business Day), the related payment of principal and interest will be made on the
next  succeeding  Business  Day as if it were made on the date such  payment was
due,  and no interest  will accrue on the amounts so payable for the period from
and after such date.


         Unless the Company shall have otherwise  provided pursuant to Section 4
of the Remarketing  Agreement,  dated as of July 2, 1997 between the Company and
Merrill  Lynch  & Co.,  Merrill  Lynch,  Pierce,  Fenner  &  Smith  Incorporated
("Merrill Lynch"), the Rate Agent will be Merrill Lynch.

         All  percentages  resulting  from any  calculation in respect of a Note
will be  rounded,  if  necessary,  to the nearest  one  hundred-thousandth  of a
percentage point, with five one-millionths of a percentage point rounded upward,
and all dollar amounts used in or resulting from such  calculation in respect of
a Note will be rounded to the nearest cent (with one-half cent rounded upward).

         Unless notice of redemption of the Notes as a whole has been given, the
Company  will  cause a notice  to be given to  holders  of Notes on the New York
Business Day (as defined below) following the Spread Determination Date for each
Subsequent  Spread  Period in the manner  described  below,  specifying  (1) the
duration of such Subsequent Spread Period,  (2) the mode (i.e.,  Fixed Rate Mode
or Floating Rate Mode), (3) the Commencement Date, (4) any redemption dates, (5)
any  redemption  type (i.e.,  par,  premium or  make-whole),  (6) any redemption
prices,  (7) the Spread for such Subsequent  Spread Period,  (8) the identity of
the  Remarketing  Underwriter,   if  applicable,  and  (9)  any  other  relevant
provisions. The term "New York Business Day" means any day other than a Saturday
or Sunday  or a day on which  banking  institutions  in The City of New York are
required or authorized to close.

         (d) Prepayment at the Option of the Company;  Redemption. The Notes are
not redeemable prior to July 9, 1998. On that date and thereafter, the Notes may
be redeemable,  at the option of the Company,  on those  Interest  Payment Dates
that  are  specified  as  redemption  dates  by the  Company  on the  applicable
Duration/Mode Determination Date, in whole or in part, upon notice thereof given
at any time during the 45 calendar day period  ending on the tenth  calendar day
prior to the redemption  date  (provided  that notice of any partial  redemption
must be  given  to the  Noteholders  at  least  15  calendar  days  prior to the
redemption  date),  in  accordance  with the  redemption  type  selected  on the
Duration/Mode  Determination  Date.  The  redemption  type to be  chosen  by the
Company and the Remarketing Underwriter on the Duration/Mode  Determination Date
may be one of the following:  (i) Par Redemption;  (ii) Premium  Redemption;  or
(iii) Make-Whole Redemption.

         (e) Tender at Option of  Beneficial  Owners.  The Company will request,
not  later  than  seven  nor more  than 15  calendar  days  prior to any  Spread
Determination  Date,  that The  Depository  Trust  Company  ("DTC")  notify  its
Participants of such Spread  Determination  Date and of the procedures that must
be  followed  if any  beneficial  owner of a Note  wishes to tender such Note as
described  herein.  If the Company and the Remarketing  Underwriter agree on the
Spread on the Spread  Determination  Date with respect to any Subsequent  Spread
Period,  each Note may be tendered to the  Remarketing  Underwriter for purchase
from  the  tendering  Noteholder  at  100%  of  its  principal  amount  and  for
remarketing by the  Remarketing  Underwriter on the calendar day (or if such day
is not a Business Day, on the next  succeeding  Business Day except as otherwise
provided herein) immediately  following the end of each Subsequent Spread Period
(the "Tender Date"). In the case of the Initial Spread Period,  the Notes may be
tendered on July 9, 1998.  Notice of a beneficial  owner's election to tender to
the Remarketing Underwriter,  which notice is irrevocable (the "Tender Notice"),
must be received by the Remarketing  Underwriter during the period commencing on
the calendar day following the Spread  Determination Date (or, if not a Business
Day, on the next succeeding Business Day) and ending at 5:00 p.m., New York City
time,  on the fifth  calendar day following  the relevant  Spread  Determination
Date. The obligation of the Remarketing  Underwriter to purchase  tendered Notes
from the  tendering  Noteholders  will be  subject  to  certain  conditions  and
termination events as provided in the Remarketing  Underwriting  Agreement.  If,
pursuant to those  certain  conditions  or  termination  events set forth in the
Remarketing   Underwriting  Agreement,  the  Remarketing  Underwriter  does  not
purchase all Notes on the relevant  Tender Date, for which a Tender Notice shall
have been given,  (1) all Tender Notices relating thereto will be null and void,
(2) none of the Notes for which such Tender  Notices  shall have been given will
be  purchased  by the  Remarketing  Underwriter  on such  Tender  Date,  (3) the
Subsequent  Spread Period will be one year, which Subsequent Spread Period shall
be deemed to have commenced on the applicable  Commencement  Date, (4) the Notes
will be reset to the  Floating  Rate Mode,  (5) the  Spread for such  Subsequent
Spread Period will be the Alternate  Spread and (6) the Notes will be redeemable
at the option of the  Company,  in whole or in part,  upon at least ten Business
Days'  notice  given by no later  than the  fifth  Business  Day  following  the
relevant  Tender  Date on the date set forth in such  notice,  which shall be no
later  than  the  last  day of such  one-year  Subsequent  Spread  Period,  at a
redemption  price equal to 100% of the principal  amount thereof,  together with
accrued  interest to the redemption  date. No beneficial owner of any Note shall
have any rights or claims against the Company or the Remarketing


                                       10

<PAGE>



Underwriter  as a result of the  Remarketing  Underwriter  not  purchasing  such
Notes, except as provided in clause (5) of the preceding sentence.

         If the Remarketing Underwriter does not purchase all Notes tendered for
purchase  on any  Tender  Date,  it will  promptly  notify the  Company  and the
Trustee.  As soon as practicable after receipt of such notice,  the Company will
cause a notice to be given to holders of the Notes  specifying  (1) the one-year
duration of the Subsequent  Spread  Period,  (2) that the Notes will be reset to
the Floating Rate Mode, (3) the Spread for such Subsequent  Spread Period (which
shall be the Alternate Spread) and (4) LIBOR for the initial Quarterly Period of
such Subsequent Spread Period.

         (f)  Form of  Notes.  The  Notes  shall be  issued  by the  Company  in
registered  form as set forth in Exhibit A attached  hereto and all of the terms
and provisions thereof are incorporated  herein by reference.  The Notes will be
issued in the form of single fully  registered  global security  without coupons
(the  "Global  Note") which will be  deposited  with,  or on behalf of, DTC, and
registered  in  the  name  of  DTC's  nominee,  Cede  &  Co.  Except  under  the
circumstance  described  below,  the Notes will not be issuable in a  definitive
form.  Unless and until it is exchanged  in whole or in part for the  individual
notes  represented  thereby,  a Global Note may not be  transferred  except as a
whole  by DTC to a  nominee  of DTC  or by a  nominee  of DTC to DTC or  another
nominee of DTC or by DTC or any nominee of DTC to a successor  depository or any
nominee of such successor.

         So long as DTC or its  nominee is the  registered  owner of such Global
Note, DTC or such nominee, as the case may be, will be considered the sole owner
or holder of the Notes  represented  by such Global Note for all purposes  under
this  Supplemental  Indenture.  Except as described below,  owners of beneficial
interest in Notes evidenced by a Global Note will not be entitled to have any of
the individual Notes  represented by such Global Note registered in their names,
will not receive or be entitled to receive  physical  delivery of any such Notes
in  definitive  form and will not be  considered  the owners or holders  thereof
under the Indenture or this Supplemental Indenture.

         If DTC is at any time  unwilling,  unable or  ineligible to continue as
depository and a successor  depository is not appointed by the Company within 90
days,  the Company will issue  individual  Notes in exchange for the Global Note
representing  such Notes.  In  addition,  the Company may at any time and in its
sole  discretion,  subject to certain  limitations  set forth in the  Indenture,
determine not to have any of such Notes  represented by one or more Global Notes
and in such event will issue individual Notes in exchange for the Global Note or
Notes  representing  such debt  Securities.  Individual  Notes so issued will be
issued in  denominations  of $1,000 and integral  multiples  thereof and will be
issued in registered form only, without coupons.

                              ADDITIONAL COVENANTS

         Section  301. In addition to the  covenants of the Company set forth in
Article Ten of the Indenture, for the benefit of the holders of the Notes:

         (a)  Limitations  on Incurrence of Debt.  (i) The Company will not, and
will not permit any Subsidiary to, incur any Debt if,  immediately  after giving
effect to the  incurrence of such  additional  Debt and the  application  of the
proceeds thereof,  the aggregate principal amount of all outstanding Debt of the
Company and its  Subsidiaries on a consolidated  basis  determined in accordance
with GAAP is greater than 60% of the sum  ("Adjusted  Total Assets") of (without
duplication)  (i) the Total Assets of the Company and its Subsidiaries as of the
end of the calendar quarter covered in the Company's Annual Report on Form 10-K,
or the Quarterly  Report on Form 10-Q,  as the case may be, most recently  filed
with the Securities and Exchange Commission (or, if such filing is not permitted
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), with
the  Trustee)  prior  to the  incurrence  of such  additional  Debt and (ii) the
purchase price of any real estate assets or mortgages receivable  acquired,  and
the amount of any securities offering proceeds received (to the extent that such
proceeds were not used to acquire real estate assets or mortgages  receivable or
used to reduce  Debt),  by the Company or any  Subsidiary  since the end of such
calendar  quarter,  including  those  proceeds  obtained in connection  with the
incurrence of such additional Debt.

         (ii) In addition to the  foregoing  limitations  on the  incurrence  of
Debt,  the Company  will not, and will not permit any  Subsidiary  to, incur any
Secured Debt if,  immediately  after  giving  effect to the  incurrence  of such
additional  Secured  Debt  and the  application  of the  proceeds  thereof,  the
aggregate  principal  amount of all outstanding  Secured Debt of the Company and
its  Subsidiaries on a consolidated  basis is greater than 40% of Adjusted Total
Assets.

         (iii) In addition to the  foregoing  limitations  on the  Incurrence of
Debt,  the Company  will not, and will not permit any  Subsidiary  to, incur any
Debt if the ratio of  Consolidated  Income  Available  for Debt  Service  to the
Annual Service  Charge for the four  consecutive  fiscal  quarters most recently
ended prior to the date on which such  additional  Debt is to be incurred  shall
have been less than 1.5x, on a pro forma basis after giving  effect  thereto and
to the application of the proceeds  therefrom,  and calculated on the assumption
that  (i)  such  Debt  and  any  other  Debt  incurred  by the  Company  and its
Subsidiaries since the first day of such four-quarter period and the application
of the proceeds therefrom, including to refinance other Debt,


                                       12

<PAGE>



had occurred at the  beginning of such period;  (ii) the repayment or retirement
of any other Debt by the  Company and its  Subsidiaries  since the first date of
such  four-quarter  period had been repaid or retired at the  beginning  of such
period  (except that, in making such  computation,  the amount of Debt under any
revolving credit facility shall be computed based upon the average daily balance
of such Debt during  such  period);  (iii) in the case of Acquired  Debt or Debt
incurred  in  connection  with  any  acquisition  since  the  first  day of such
four-quarter period, the related acquisition had occurred as of the first day of
such period with appropriate  adjustments with respect to such acquisition being
included in such pro forma calculation;  and (iv) in the case of any acquisition
or  disposition  by the  Company  or its  Subsidiaries  of any asset or group of
assets since the first day of such four-quarter period, whether by merger, stock
purchase or sale, or asset purchase or sale, such  acquisition or disposition or
any related  repayment  of Debt had  occurred as of the first day of such period
with the appropriate adjustments with respect to such acquisition or disposition
being included in such pro forma calculation.

         (b)  Maintenance  of Total  Unencumbered  Assets.  The  Company and its
Subsidiaries  will maintain Total  Unencumbered  Assets of not less than 200% of
the aggregate  outstanding principal amount of the Unsecured Debt of the Company
and its Subsidiaries on a consolidated basis.

         (c)  Applicability  of Discharge,  Defeasance  and Covenant  Defeasance
Provisions.  The  Discharge,  Defeasance and Covenant  Defeasance  provisions in
Article Fourteen of the Indenture will apply to the Notes.

                                  ARTICLE FOUR

                          ADDITIONAL EVENTS OF DEFAULT

         For purposes of this Supplemental  Indenture and the Notes, in addition
to the Events of Default  set forth in Section  501 of the  Indenture,  it shall
also  constitute  an "Event of Default"  if an event of default  under any bond,
debenture,  note or other evidence of indebtedness of the Company  (including an
event of default with respect to any other series of  securities),  or under any
mortgage,  indenture or other instrument of the Company under which there may be
issued or by which there may be secured or  evidenced  any  indebtedness  of the
Company (or by any Subsidiary, the repayment of which the Company has guaranteed
or for which the  Company  is  directly  responsible  or  liable as  obligor  or
guarantor),  whether such indebtedness now exists or shall hereafter be created,
shall  happen  and  shall  result in an  aggregate  principal  amount  exceeding
$20,000,000  becoming or being  declared  due and  payable  prior to the date on
which it would otherwise have become due and payable,  without such indebtedness
having been discharged,  or such acceleration having been rescinded or annulled,
within a period of ten days after there shall have been given,  by registered or
certified  mail, to the Company by the Trustee or to the Company and the Trustee
by the holders of at least 25% in principal  amount of the outstanding  Notes, a
written notice  specifying  such default and requiring the Company to cause such
indebtedness  to be  discharged  or cause such  acceleration  to be rescinded or
annulled and stating that such notice is a "Notice of Default" hereunder.

                               TERMS OF THE NOTES

         Section 2.1 Pursuant to Section 301 of the  Indenture,  the Notes shall
have the following terms and conditions:

         (a) Title; Limitation on Aggregate Principal Amount; Form of Notes. The
Notes shall be known as the Company's  $100,000,000 6.70% Senior Notes due 2005.
The Notes will be limited to an aggregate principal amount of $100,000,000.  The
Notes  (together  with the Trustee's  certificate  of  authentication)  shall be
substantially in the form of Exhibit A hereto,  which is hereby  incorporated in
and made a part of this Supplemental Indenture.

         The Notes will be issued in the form of single fully registered  global
security without coupons (the "Global Note") which will be deposited with, or on
behalf of, The Depository Trust Company  ("DTC"),  and registered in the name of
DTC's nominee,  Cede & Co. Except under the  circumstance  described  below, the
Notes  will  not be  issuable  in a  definitive  form.  Unless  and  until it is
exchanged in whole or in part for the individual notes represented  thereby, the
Global Note may not be transferred  except as a whole by DTC to a nominee of DTC
or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any nominee
of DTC to a successor depository or any nominee of such successor.

         So long as DTC or its  nominee is the  registered  owner of such Global
Note, DTC or such nominee, as the case may be, will be considered the sole owner
or holder of the Notes  represented  by such Global Note for all purposes  under
this  Supplemental  Indenture.  Except as described below,  owners of beneficial
interest in Notes  evidenced by the Global Note will not be entitled to have any
of the  individual  Notes  represented  by such Global Note  registered in their
names,  will not receive or be entitled to receive physical delivery of any such
Notes in  definitive  form and will not be  considered  the  owners  or  holders
thereof under the Indenture or this Supplemental Indenture.

         If DTC is at any time  unwilling,  unable or  ineligible to continue as
depository and a successor  depository is not appointed by the Company within 90
days,  the Company will issue  individual  Notes in exchange for the Global Note
representing  such Notes.  In  addition,  the Company may at any time and in its
sole  discretion,  subject to certain  limitations  set forth in the  Indenture,
determine not to have any of such Notes  represented by one or more Global Notes
and in such event will issue individual Notes in exchange for the Global Note or
Notes  representing  such debt  Securities.  Individual  Notes so issued will be
issued in  denominations  of $1,000 and integral  multiples  thereof and will be
issued in registered form only, without coupons.

         (b) Principal Repayment;  Currency. The Stated Maturity of the Notes is
February 23, 2005,  provided,  however, the Notes may be earlier redeemed at the
option of the Company as provided in paragraph (c) below.  The principal of each
Note  payable  on its  maturity  date  shall be paid  against  presentation  and
surrender  thereof  at  the  Corporate  Trust  Office  of the  Trustee,  located
initially at Two International Place, Boston,  Massachusetts 02110, in such coin
or currency of the United States of America as at the time of

                                       -4-

payment is legal tender for the payment of public or private debts.  The Company
will not pay Additional Amounts (as defined in the Indenture) on the Notes.

         (c)  Redemption at the Option of the Company;  Acceleration.  The Notes
will be subject to redemption at any time at the option of the Company, in whole

                              ADDITIONAL COVENANTS

         Section 3.1 In addition  to the  covenants  of the Company set forth in
Article Ten of the Indenture, for the benefit of the holders of the Notes:

         (a)      Limitations on Incurrence of Debt.

                  (i) The Company will not,  and will not permit any  Subsidiary
         to,  incur  any  Debt  if,  immediately  after  giving  effect  to  the
         incurrence of such  additional Debt and the application of the proceeds
         thereof,  the aggregate principal amount of all outstanding Debt of the
         Company and its  Subsidiaries  on a  consolidated  basis  determined in
         accordance  with GAAP is greater than 60% of the sum  ("Adjusted  Total
         Assets") of (without  duplication)  (i) the Total Assets of the Company
         and its  Subsidiaries as of the end of the calendar  quarter covered in
         the Company's  Annual  Report on Form 10-K, or the Quarterly  Report on
         Form 10-Q, as the case may be, most recently  filed with the Securities
         and Exchange  Commission (or, if such filing is not permitted under the
         Securities  Exchange Act of 1934, as amended (the "Exchange Act"), with
         the Trustee) prior to the incurrence of such  additional  Debt and (ii)
         the purchase price of any real estate assets or mortgages receivable

                                       -5-

<PAGE>

         acquired,  and the amount of any securities  offering proceeds received
         (to the extent that such  proceeds were not used to acquire real estate
         assets or mortgages  receivable or used to reduce Debt), by the Company
         or any  Subsidiary  since the end of such calendar  quarter,  including
         those  proceeds  obtained in  connection  with the  incurrence  of such
         additional Debt.

                  (ii)  In  addition  to  the  foregoing   limitations   on  the
         incurrence  of Debt,  the  Company  will not,  and will not  permit any
         Subsidiary  to,  incur any Secured  Debt if,  immediately  after giving
         effect  to the  incurrence  of such  additional  Secured  Debt  and the
         application of the proceeds thereof,  the aggregate principal amount of
         all outstanding  Secured Debt of the Company and its  Subsidiaries on a
         consolidated basis is greater than 40% of Adjusted Total Assets.

                  (iii)  In  addition  to  the  foregoing   limitations  on  the
         Incurrence  of Debt,  the  Company  will not,  and will not  permit any
         Subsidiary  to,  incur  any Debt if the  ratio of  Consolidated  Income
         Available  for Debt  Service to the Annual  Debt  Service  for the four
         consecutive  fiscal  quarters most recently  ended prior to the date on
         which such  additional Debt is to be incurred shall have been less than
         1.5x,  on a pro forma  basis  after  giving  effect  thereto and to the
         application of the proceeds therefrom, and calculated on the assumption
         that (i) such Debt and any other Debt  incurred  by the Company and its
         Subsidiaries  since the first day of such  four-quarter  period and the
         application  of the proceeds  therefrom,  including to refinance  other
         Debt, had occurred at the beginning of such period;  (ii) the repayment
         or  retirement  of any other Debt by the Company  and its  Subsidiaries
         since the first date of such  four-quarter  period  had been  repaid or
         retired at the  beginning of such period  (except  that, in making such
         computation,  the amount of Debt under any  revolving  credit  facility
         shall be  computed  based upon the average  daily  balance of such Debt
         during  such  period);  (iii)  in the  case  of  Acquired  Debt or Debt
         incurred in connection with any acquisition since the first day of such
         four-quarter  period,  the related  acquisition  had occurred as of the
         first day of such period with  appropriate  adjustments with respect to
         such acquisition being included in such pro forma calculation; and (iv)
         in the case of any  acquisition  or  disposition  by the Company or its
         Subsidiaries  of any  asset or group of  assets  since the first day of
         such four-quarter period, whether by merger, stock purchase or sale, or
         asset purchase or sale, such  acquisition or disposition or any related
         repayment  of Debt had occurred as of the first day of such period with
         the  appropriate  adjustments  with  respect  to  such  acquisition  or
         disposition being included in such pro forma calculation.

         (b)  Maintenance  of Total  Unencumbered  Assets.  The  Company and its
Subsidiaries  will maintain Total  Unencumbered  Assets of not less than 200% of
the aggregate  outstanding principal amount of the Unsecured Debt of the Company
and its Subsidiaries on a consolidated basis.

         (c)  Applicability  of Discharge,  Defeasance  and Covenant  Defeasance
Provisions.  The  Discharge,  Defeasance and Covenant  Defeasance  provisions in
Article Fourteen of the Indenture will apply to the Notes.

                                    ARTICLE 4

         For purposes of this Supplemental  Indenture and the Notes, in addition
to the Events of Default  set forth in Section  501 of the  Indenture,  it shall

debenture,  note or other evidence of indebtedness of the Company  (including an
event of default with respect to any other series of  securities),  or under any
mortgage,  indenture or other instrument of the Company under which there may be
issued or by which there may be secured or  evidenced  any  indebtedness  of the
Company (or by any Subsidiary, the repayment of which the Company has guaranteed
or for which the  Company  is  directly  responsible  or  liable as  obligor  or
guarantor), whether such indebtedness now exists

                                       -6-

or shall  hereafter  be created,  shall  happen and shall result in an aggregate
principal  amount  exceeding  $20,000,000  becoming  or being  declared  due and
payable  prior  to the date on which it  would  otherwise  have  become  due and
payable, without such indebtedness having been discharged,  or such acceleration
having been rescinded or annulled, within a period of ten days after there shall
have been given,  by registered or certified mail, to the Company by the Trustee
or to the Company  and the  Trustee by the holders of at least 25% in  principal
amount of the  outstanding  Notes, a written notice  specifying such default and
requiring the Company to cause such  indebtedness to be discharged or cause such
acceleration  to be  rescinded  or annulled  and  stating  that such notice is a
"Notice of Default" hereunder.

                                    ARTICLE 5

                                  EFFECTIVENESS

STATE STREET BANK AND TRUST COMPANY, as Trustee

                                 (Back of Note)

                     HEALTH AND RETIREMENT PROPERTIES TRUST

                           6.70% Senior Notes due 2005

         Capitalized terms used herein have the meanings assigned to them in the
Indenture (as defined below) unless otherwise indicated.

         1. Interest.  Health and Retirement  Properties  Trust, a Maryland real
estate  investment  trust  (the  "Company"),  promises  to pay  interest  on the
principal amount of this Note at the rate and in the manner specified below.

         The Company shall pay in cash interest on the principal  amount of this
Note at the rate per annum of 6.70%. The Company will pay interest semi-annually
in arrears on February 23 and August 23 of each year,  commencing  on August 23,
1998 or if any such day is not a Business Day (as defined in the Indenture),  on
the next succeeding  Business Day (each an "Interest  Payment Date"), to Holders
of record on the immediately preceding February 8 and August 8.

         Interest will be computed on the basis of a 360-day year  consisting of
twelve 30-day  months.  Interest shall accrue from the most recent date to which
interest  has been paid or, if no interest  has been paid,  from the date of the
original issuance of the Notes.

         2.  Method of  Payment.  The  Company  will pay  interest  on the Notes
(except defaulted  interest) to the Persons who are registered  Holders of Notes
at the close of business on the record date next preceding the Interest  Payment
Date,  even if such Notes are  canceled  after such record date and on or before
such Interest Payment Date. The Company will pay principal and interest in money
of the United  States that at the time of payment is legal tender for payment of
public and private debts. The Company,  however, may pay principal,  premium, if
any, and interest by check payable in such money.  It may mail an interest check
to a Holder's registered address.

         3. Indenture.  The Company issued the Notes under an Indenture dated as
of July 9,  1997,  as  supplemented  by a  Supplemental  Indenture  dated  as of
February 23, 1998 (the  "Indenture")  between the Company and the  Trustee.  The
terms of the Notes  include those stated in the Indenture and those made part of
the  Indenture  by reference to the Trust  Indenture  Act of 1939 (15 U.S.  Code
ss.ss.  77aaa-77bbbb)  as in effect on the date of the Indenture.  The Notes are
subject  to all such  terms,  and  Holders  of the  Notes  are  referred  to the
Indenture and such act for a statement of such terms. The terms of the Indenture
shall govern any inconsistencies  between the Indenture and the Notes. The Notes
are unsecured  general  obligations of the Company  limited to  $100,000,000  in
aggregate principal amount.

         4. Optional Redemption.  The Notes will be subject to redemption at any
time at the option of the  Company,  in whole or in part,  upon not less than 30
nor more than 60 days' notice, at a redemption price equal to the sum of (i) the
principal  amount of the Notes being redeemed,  plus accrued and unpaid interest
to but excluding the applicable redemption date and (ii) the Make-Whole Amount.

         As used herein the term  "Make-Whole  Amount" means, in connection with
any optional  redemption or accelerated payment of any Note, the excess, if any,
of (i)  the  aggregate  present  value  as of the  date of  such  redemption  or
accelerated  payment of each dollar of principal  being redeemed or paid and the
amount of interest  (exclusive of interest  accrued to the date of redemption or
accelerated  payment)  that would have been payable in respect of such dollar if
such  redemption  or  accelerated  payment  had not  been  made,  determined  by
discounting,  on  a  semiannual  basis,  such  principal  and  interest  at  the
Reinvestment Rate (as defined

                                      A - 2
<PAGE>

herein)  (determined on the third Business Day preceding the date such notice of
redemption is given or declaration of  acceleration is made) from the respective
dates on which such  principal  and  interest  would  have been  payable if such
redemption  or  accelerated  payment had not been made,  over (ii) the aggregate
principal amount of the Notes being redeemed or paid.

         As used  herein  the term  "Reinvestment  Rate"  means a rate per annum
equal to the sum of 0.25%  (twenty-five  one hundredths of one percent) plus the
yield on treasury  securities  at  constant  maturity  under the  heading  "Week
Ending"  published  in the  Statistical  Release (as defined  herein)  under the
caption "Treasury Constant  Maturities" for the maturity (rounded to the nearest
month)  corresponding to the remaining life to maturity,  as of the payment date
of the principal being redeemed or paid. If no maturity  exactly  corresponds to
such   maturity,   yields  for  the  two  published   maturities   most  closely
corresponding  to such maturity shall be calculated  pursuant to the immediately
preceding   sentence  and  the  Reinvestment   Rate  shall  be  interpolated  or
extrapolated from such yields on a straight-line basis, rounding in each of such
relevant  periods  to  the  nearest  month.  For  purposes  of  calculating  the
Reinvestment  Rate, the most recent  Statistical  Release published prior to the
date of determination of the Make-Whole Amount shall be used.

         As used herein the term  "Statistical  Release"  means the  statistical
release designated "H. 15(519)" or any successor  publication which is published
weekly by the Federal  Reserve System and which  establishes  yields on actively
traded United States government  securities  adjusted to constant maturities or,
if such  statistical  release is not published at the time of any  determination
under the Supplemental  Indenture,  then such other reasonably  comparable index
which shall be designated by the Company.

         5.  Mandatory  Redemption.  The  Company  shall not be required to make
sinking fund or redemption payments with respect to the Notes.

         6. Notice of Redemption.  Notice of redemption shall be mailed at least
30 days but not more than 60 days before the  redemption  date to each Holder of
Notes to be redeemed at its  registered  address.  Notes may be redeemed in part
but only in whole multiples of $1,000,  unless all of the Notes held by a Holder
are to be redeemed.  On and after the redemption date, interest ceases to accrue
on Notes or portions of them called for redemption.

         7. Denominations,  Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples  thereof.  The
transfer of Notes may be  registered  and Notes may be  exchanged as provided in
the Indenture.  The Registrar and the Trustee may require a Holder,  among other
things, to furnish  appropriate  endorsements and transfer  documents and to pay
any taxes and fees required by law or permitted by the Indenture.  The Registrar
need not  exchange  or  register  the  transfer of any Note or portion of a Note
selected for redemption.  Also, it need not exchange or register the transfer of
any Notes for a period of 15 days before the  mailing of a notice of  redemption
of Notes,  or during  the  period  between a record  date and the  corresponding
Interest Payment Date.

         8.  Defaults and  Remedies.  In case an Event of Default (as defined in
the Indenture)  with respect to the Notes shall have occurred and be continuing,
the principal hereof may be declared,  and upon such  declaration  shall become,
due and payable,  in the manner,  with the effect and subject to the  provisions
provided in the Indenture.

         9. Actions of Holders. The Indenture contains provisions permitting the
holders of not less than a majority  of the  aggregate  principal  amount of the
outstanding  Notes, on behalf of the holders of all such Notes at a meeting duly
called and held as provided in the Indenture, to make, give or take any request,
demand,  authorization,  direction,  notice,  consent,  waiver  or other  action
provided  in the  Indenture  to be made,  given or taken by the  holders  of the
Notes, including without limitation,  waiving (a) compliance by the Company with
certain  provisions of the  Indenture,  and (b) certain past defaults  under the
Indenture and their

                                      A - 3
<PAGE>

consequences.  Any  resolution  passed or  decision  taken at any meeting of the
holders of the Notes in accordance with the provisions of the Indenture shall be
conclusive  and binding  upon such  holders and upon all future  holders of this
Note and other Notes  issued  upon the  registration  of  transfer  hereof or in
exchange heretofore or in lieu hereof

         10. Persons Deemed Owners. The Company,  the Trustee,  and any agent of
the Company or the Trustee may deem and treat the Person in whose name this Note
is registered on the Security Register as its absolute owner for all purposes.

         11. Authentication. This Note shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

         12.   Governing   Law.  THE  INTERNAL  LAW  OF  THE   COMMONWEALTH   OF
MASSACHUSETTS SHALL GOVERN AND BE USED TO CONSTRUE THE INDENTURE AND THE NOTES.

         13. No Personal  Liability.  THE AMENDED AND  RESTATED  DECLARATION  OF
TRUST OF THE  COMPANY,  DATED JULY 1, 1994, A COPY OF WHICH,  TOGETHER  WITH ALL
AMENDMENTS  THERETO  (THE  "DECLARATION"),  IS DULY  FILED IN THE  OFFICE OF THE

OBLIGATION  OF, OR CLAIM  AGAINST,  THE  COMPANY.  ALL PERSONS  DEALING WITH THE
COMPANY,  IN ANY WAY,  SHALL  LOOK  ONLY TO THE  ASSETS OF THE  COMPANY  FOR THE
PAYMENT OF ANY SUM OR THE PERFORMANCE OF ANY OBLIGATION.

         The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture. Request may be made to:

Health and Retirement Properties Trust
400 Centre Street
Newton, Massachusetts 02158

Ladies and Gentlemen:

         In  connection  with the  filing by Health  and  Retirement  Properties
Trust, a Maryland real estate  investment trust (the  "Company"),  of its Annual
Report on Form 10-K for the year ended  December  31,  1997 (the  "Form  10-K"),
under the Securities  Exchange Act of 1934, as amended (the "Exchange Act"), the
following  opinion  is  furnished  to you to be filed  with the  Securities  and
Exchange Commission (the "SEC") as Exhibit 8.1 to the Form 10-K.

         We have  acted  as  counsel  for the  Company  in  connection  with the
preparation  of its  Form  10-K,  and we  have  examined  originals  or  copies,
certified or otherwise  identified to our  satisfaction,  of corporate  records,
certificates  and  statements of officers and  accountants of the Company and of
public  officials,  and such other documents as we have considered  relevant and
necessary in order to furnish the opinion  hereinafter set forth.  Specifically,
and without limiting the generality of the foregoing,  we have reviewed: (i) the
declaration of trust,  as amended and restated,  and the by-laws of the Company;
and (ii) the sections in the Company's Form 10-K captioned  "Federal  Income Tax
Considerations"  and  "ERISA  Plans,  Keogh  Plans  and  Individual   Retirement
Accounts."  With  respect to all  questions  of fact on which such  opinions are
based,  we have assumed the accuracy and  completeness of and have relied on the
information set forth in the Form 10-K and in the documents incorporated therein
by reference,  and on representations made to us by the officers of the Company.
We have not  independently  verified such  information;  nothing has come to our
attention,  however,  which would lead us to believe that we are not entitled to
rely on such information.

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

the Department of Labor regulations issued thereunder,  published administrative
interpretations  thereof, and judicial decisions with respect thereto, all as of
the date hereof (collectively, the "ERISA Laws"). No assurance can be given that
the Tax Laws or the ERISA Laws will not change.  In  preparing  the  discussions
with respect to the matters in the sections of the Form 10-K captioned  "Federal
Income  Tax  Considerations"  and  "ERISA  Plans,  Keogh  Plans  and  Individual
Retirement  Accounts," we have made certain  assumptions  and expressed  certain
conditions and qualifications therein, all of which assumptions,  conditions and
qualifications are incorporated herein by reference.

         Based upon and subject to the foregoing, we are of the opinion that the
discussions  in the  sections  of the Form 10-K  captioned  "Federal  Income Tax
Considerations"  and  "ERISA  Plans,  Keogh  Plans  and  Individual   Retirement
Accounts,"  in all material  respects are accurate and fairly  summarize the Tax
Laws issues and ERISA Laws issues addressed therein, and hereby confirm that the
opinions of counsel  referred to in said sections  represent our opinions on the
subject matter thereof.

         We hereby consent to the  incorporation of this opinion by reference as
an exhibit to the Form 10-K and to the reference to our firm therein.  In giving
such  consent,  we do not  thereby  admit that we come  within the  category  of
persons whose consent is required under Section 7 of the Securities Act of 1933,
as  amended,  or  under  the  rules  and  regulations  of  the  SEC  promulgated
thereunder.

                                           Very truly yours,


                                           /s/ Sullivan & Worcester LLP

         NOW,  THEREFORE,  in  consideration of the premises and the agreements,

as follows:

         1. Amendments to Loan Agreement.

         (a)  Section  1.1  of the  Loan  Agreement  is  hereby  amended  by the
amendment and restatement of the definition of "Facility" as follows:-

                  ""Facility" means each (i) operating  facility offering health
                  care or  related  services  or  rehabilitation  or  retirement

                  Interests  associated with such facility) in which Borrower or

                  or any of its  Subsidiaries to a Government  Agency or, in the
                  case of a Medical  Office  Asset,  for  medical  research  and
                  development  or,  in the  case of a Fee or  Mortgage  Interest

comma,  deleting the period at the end thereof and adding the following  proviso
at the end thereof:-

                  ", and (vi)  notwithstanding the preceding  provisions of this
                  Section  6.7,  Borrower  shall  not be deemed to have made any
                  material  change in the nature of its  business  as  presently
                  conducted  to  the  extent  that  the  Borrower  directly,  or
                  indirectly  through a  Subsidiary,  acquires or  operates,  or
                  acquires or funds a Mortgage  Interest  in,  income  producing
                  real  property   interests  and   facilities   not  heretofore

                  Properties  and  Mortgage  Interests  of the  Borrower and its
                  Subsidiaries  on a  consolidated  basis  determined (x) at the
                  time of such  acquisition  or (y) if a facility is at the time
                  of its  acquisition  of a type  heretofore  described  in this
                  Section  6.7  but  is  thereafter  converted  to  a  type  not
                  heretofore so described,  on the date of such conversion,  and
                  (ii) are not treated by the Borrower as Eligible Properties or
                  Eligible  Mortgages,  as the case may be,  for any  purpose of
                  this Agreement."

         (c) Sections 7.1 (r) and (s) of the Loan  Agreement are hereby  amended
and restated as follows:

                  aggregate   Allowed  Value  of  the  Properties  and  Mortgage
                  Interests  shall be  attributable  to  Medical  Office  Assets
                  and/or Clinics; or"

         (d) Sections 7.1 (t), (u) and (v) are hereby renumbered as Sections 7.1
  (s), (t) and (u), respectively.

         2. Conditions to Effectiveness.

correct and complete:

the Amended  Agreement have been authorized by all necessary  action on the part
of Borrower.

                                        3
<PAGE>


         (c) The  execution  and delivery by Borrower of this  Amendment and the
performance  by  Borrower  of the  Amended  Agreement  and the  use of  proceeds
thereunder (i) do not violate any  Requirement of Law or Contractual  Obligation
of Borrower,  (ii) will not result in, or require, the creation or imposition of
any Lien on any of its properties or revenues pursuant to any Requirement of Law
or  Contractual  Obligation  of Borrower and (iii) do not require the consent of
any third party.

         (d) This  Amendment and the Amended  Agreement  have been duly executed
and delivered by Borrower and are the legally valid and binding  obligations  of
Borrower,  enforceable  against  Borrower in  accordance  with their  respective
terms,  except  as  enforceability  may be  limited  by  applicable  bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally.

         (e) The  representations  and warranties  contained in Section 3 of the
Loan  Agreement  are and will be true,  correct  and  complete  in all  material
respects  on and as of the  effective  date  described  in Section 2 to the same

representations and warranties  specifically relate to an earlier date, in which
case they were true,  correct and complete in all material respects on and as of
such earlier date.

         (f) After giving effect to this Amendment, no event has occurred and is
continuing or will result from the consummation of the transactions described in
or otherwise  contemplated by this Amendment that would  constitute a Default or
an Event of Default.

         (g)  The  Declaration  of  Trust,   By-Laws  and  other  organizational
documents of Borrower have not been amended  since May 14, 1997,  and the copies
thereof  delivered to Lenders  under the Loan  Agreement  are true,  correct and

         Each of Retirement Properties,  Causeway,  SJO, the Trust Subsidiaries,
the  Delaware  Subsidiaries  and the LLC  (each a  "Subsidiary  Guarantor")  has
guarantied the obligations of Borrower under Section 9 of the Loan Agreement.

         Each Subsidiary  Guarantor hereby acknowledges that it has reviewed the

amendments or waivers to the Loan Agreement.

         7.  Execution in  Counterparts.  This  Amendment may be executed in any
number  of   counterparts,   and  by  different   parties   hereto  in  separate
counterparts,  each of which when so executed and  delivered  shall be deemed an
original,  but all such counterparts taken together shall constitute but one and
the same instrument.

         8. Headings. Section headings in this Amendment are included herein for
convenience  of reference only and shall not constitute a part of this Amendment

provisions of Section 10.4 of the Loan Agreement, the amendments set forth above
shall be limited  precisely as written,  and nothing in this Amendment  shall be
deemed to prejudice  any right or remedy that any Lender may now have (except to
the extent such right or remedy was based upon  existing  defaults that will not
exist after giving effect to this  Amendment) or may have in the future under or
in  connection  with the Loan  Agreement  or any other  instrument  or agreement
referred to therein.

Item 5.  Other Events

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations

     The  following  information  is provided in  connection  with the financial
statements  filed  as  Item 7 to  this  Current  Report  and  should  be read in
conjunction with the financial  statements and notes thereto included  elsewhere
herein.

Results of Operations
Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

     Total  revenues for the year ended  December  31, 1997  increased to $208.9
million from $120.2 million for the year ended December 31, 1996.  Rental income
increased  by $90.0  million and  interest  and other  income  decreased by $1.3
million. Rental income increased because of new real estate investments in 1997,
and partly as a result of the Company's increased  investments in "gross leased"
real estate assets as compared to "net leased"  assets during the 1997 period as
compared to the 1996 period. As the Company's  investment in such "gross leased"
assets increases,  the Company  anticipates  rental income and the corresponding
operating  expenses  from such leases to  increase  during  subsequent  periods.
Interest and other income  decreased  primarily as a result of  prepayments  and
repayments of mortgage investments, which was offset, in part, by an increase in
earnings on the Company's short-term  investments in the 1997 period compared to
the 1996 period.

     Total  expenses for the year ended  December  31, 1997  increased to $114.5
million  from $55.5  million for the year ended  December  31,  1996.  Operating
expenses  increased  by $23.0  million  as a result of the  Company's  increased
investment  in "gross  leased"  real  estate  assets  during the 1997  period as
compared to the 1996 period.  Interest expense increased by $14.2 million due to
higher  borrowings during the 1997 period.  Depreciation and  amortization,  and
general and administrative expenses increased by $17.2 million and $4.6 million,
respectively,  primarily as a result of new real estate  investments in 1997 and
1996.

     Net income  increased to $114.0  million,  or $1.24 per basic share for the
1997 period,  from $73.3 million,  or $1.11 per basic share for the 1996 period.
Net income increased  primarily as a result of new investments in 1997 and 1996.
In addition,  net income increased as a result of a $2.9 million gain on sale of
properties,  the recognition of a $9.3 million gain on equity transaction of the
Company's formerly wholly owned subsidiary  Hospitality Properties Trust ("HPT")
during the 1997 period  compared to a $3.6 million gain in the 1996 period,  and
by an  extraordinary  loss of $1.1 million during the 1997 period  compared to a
$3.9 million  extraordinary loss during the 1996 period, both resulting from the
early  extinguishment  of debt. HPT is a real estate  investment trust investing
principally in income producing hotel real estate.  The Company's  investment in
HPT is accounted for using the equity method.

     The Company's  business goal is to maximize funds from  operations  ("FFO")
rather than net income.  The Company's  Board of Trustees  considers  FFO, among
other  factors,  when  determining  dividends  to be paid to  shareholders.  The
Company has adopted the National  Association of Real Estate Investment  Trust's
("NAREIT")  definition  of FFO as income  before equity in earnings of HPT, gain
(loss) on HPT's  equity  transaction,  gain  (loss) on sale of real  estate  and
extraordinary  items, plus depreciation,  other non-cash items and the Company's
proportionate  share of HPT's  FFO.  Funds  from  operations  for the year ended
December 31, 1997, were $146.3 million,  or $1.59 per basic share,  versus $99.1
million,  or $1.50 per basic  share,  in 1996.  Funds from  operations  for 1997
increased  $47.2  million,  or 47.6%,  over the prior year.  The increase is the
result of new  investments  in 1997 and 1996.  Dividends  declared for the years
ended December 31, 1997 and 1996 were $144.3 million,  or $1.46 per basic share,
and $94.3 million, or $1.42 per basic share,  respectively.  Dividends in excess
of net income  constitute a return of capital.  For 1997,  the return of capital
portion  reported was 17.4% of dividends and the long-term  capital gain portion
was 1.7% of  dividends.  Cash flow  provided by  operating  activities  and cash
available for  distribution  may not necessarily  equal funds from operations as
the cash flow of the Company is affected  by other  factors not  included in the
funds from operations calculation, such as changes in assets and liabilities.

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations

     Cash  flows  provided  by (used for)  operating,  investing  and  financing
activities   were  $185.7   million,   ($815.2)   million  and  $630.0  million,
respectively,  for the year ended December 31, 1997 and $98.3 million,  ($235.3)
million and $140.2 million,  respectively, for the year ended December 31, 1996.
The  increases  in all three  categories  are  primarily  the result of new real
estate investments in 1997.

Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

     Total revenues for the year ended December 31, 1996 were $120.2 million, an
increase of $6.9 million over the year ended  December 31, 1995.  Rental  income
increased  to $98.0  million  from $90.2  million and  interest and other income
decreased to $22.1 million from $23.1 million.  Rental income increased as a net
result of new real estate  investments  during 1996,  offset by the exclusion of
rental revenue from HPT.  During 1995, HPT completed its initial public offering
and the Company's investment in HPT is accounted for using the equity method and
the 1996 period does not include revenue and expenses of HPT. Interest and other
income  decreased  as a net  result  of the  scheduled  and early  repayment  of
mortgage loans acquired from the Resolution  Trust Company in 1992 and 1993. The
Company  anticipates  that  such  prepayments  will  continue  and  consequently
interest  income will decline in the future.  This interest  income  decline was
partially  offset in 1996 by short-term  investment  income on excess cash which
resulted from the Company's issuance of convertible debentures during the fourth
quarter of 1996.

     Total  expenses for 1996  increased to $55.5  million from $54.7 million in
1995.  The  increase  of $0.8  million  is the net  result of higher  operating,
general and  administrative  expenses during the 1996 period.  Interest  expense
declined  due to lower  borrowings  and  lower  interest  rates  during  1996 as
compared to 1995.  Depreciation  expense was  essentially  unchanged  as the net
result of new real  estate  investments  during 1996 which was offset by the HPT
transaction described above.  Amortization expense declined due to the write-off
of deferred finance fees in March 1996 and October 1996.

     Net income for 1996 increased to $73.3  million,  or $1.11 per basic share,
from $64.2  million,  or $1.08 per basic share,  in 1995.  These  increases  are
primarily the result of net new real estate  investments  and the recognition of
the gain on the equity transaction of HPT.

     Cash  flows  provided  by (used for)  operating,  investing  and  financing
activities were $98.3 million, ($235.3) million and $140.2 million, respectively
for the year ended  December 31, 1996 and $82.3  million,  ($190.3)  million and
$68.8 million, respectively, for the year ended December 31, 1995.

Liquidity and Capital Resources

     Total assets of the Company  increased to $2.1 billion at December 31, 1997
from  $1.2  billion  as  of  December  31,  1996.   The  increase  is  primarily
attributable to the Company's new real estate investments during 1997.

     During 1997, the Company acquired three nursing properties,  one retirement
community,  22 medical and other office  buildings and 20 medical clinics for an
aggregated  amount of $554.8 million and provided debt financing and improvement
funding  totaling $4.8 million to its existing  properties.  These  transactions
were  funded  by  borrowing  on the  Company's  revolving  credit  facility  and
available  cash. In addition,  the Company sold 14 nursing  properties for $33.5
million,  which  resulted in a gain of $2.9  million.  During 1997,  the Company
received  regularly  scheduled  principal payments and prepayment on real estate
mortgages of approximately $49.5 million.

     In February 1997,  the Company  agreed to acquire 30 office  buildings (the
"Government  Properties")  leased  to  various  agencies  of the  United  States
Government.  As of December 31, 1997,  the Company had completed the purchase of
29 of the  Government  Properties  for $439.5 million and elected not to acquire
one of the  Government  Properties  under  development.  The  acquisition of the
Government  Properties was funded,  in part, with the proceeds from the issuance
of the Company's  common shares pursuant to a public  offering,  the issuance of
4,019,429 common shares of the Company in a private placement and the assumption
of $27.6 million of debt. Subsequently, in January 1998, the Company sold one of
the Government  Properties  for $5.7 million;  no gain or loss was recognized on
the sale of this property.

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations

     At December  31, 1997,  the Company  owned 4.0  million,  or 10.3%,  of the
common  shares of  beneficial  interest  of HPT with a carrying  value of $111.1
million  and a  market  value of  $131.5  million.  During  December  1997,  HPT
completed a public stock  offering of 12.0 million  common  shares of beneficial
interest  at  a  per  share  price  of  $33.0625  for  total   consideration  of
approximately  $396.8 million.  As a result of this  transaction,  the Company's
ownership  percentage  in HPT was  reduced  from 14.9% to 10.3% and the  Company
realized a gain of $9.3  million.  Although the Company did not sell any shares,
pursuant to the Company's accounting policy, gains and losses on the issuance of
common  shares of  beneficial  interest by HPT are  recognized  in the Company's
income statement. These amounts are not included in the Company's calculation of
FFO.

     In March 1997, the Company issued 27,025,000 common shares and received net
proceeds of $483.2  million.  The proceeds  were used to acquire the  Government
Properties.

     In March  1997,  the  Company  extended  and  modified  its $250.0  million
unsecured  revolving  bank  credit  facility.  Subsequently,  in July 1997,  the
Company  expanded the credit  facility to $450.0  million.  The  revolving  bank
credit facility matures in 2001 and bears interest at LIBOR plus a premium.

     During July 1997,  the Company  issued senior  unsecured  Remarketed  Reset
Notes (the "Notes")  totaling $200.0 million.  The Notes are due in 2007 and the
initial interest rate is LIBOR plus a premium,  reset  quarterly.  In July 1998,
these Notes may be prepaid without a premium,  or the interest rate and interest
period  on these  Notes  may be fixed  for the  balance  of the term or a lesser
period at the Company's  option and the Notes will be remarketed.  Proceeds from
the issuance of the Notes were used to prepay  $125.0  million of the  Company's
Floating  Rate Senior Notes,  Series B, due 1999 and $75.0  million  outstanding
under the Company's  revolving  bank credit  facility.  In connection  with this
refinancing,  the Company  recognized an extraordinary loss of $1.1 million from
the write-off of unamortized deferred financing costs.

     In December 1997, the Company issued unsecured Senior Notes totaling $150.0
million.  The notes bear interest at 6.75% and mature in 2002. Net proceeds from
the notes were used for general  business  purposes and to repay $140.0  million
then outstanding under the Company's revolving bank credit facility.

     At  December  31,  1997,  the  Company  had $22.4  million of cash and cash
equivalents  and had drawn $200.0 million of the $450.0  million  revolving bank
credit  facility.  In addition,  in May 1997,  the Company  filed a $1.0 billion
Shelf  Registration  Statement (the "Shelf") that has been declared effective by
the Securities and Exchange Commission. At December 31, 1997, $800.0 million was
available to be drawn on the Shelf.

     As of December 31, 1997, the Company had commitments to provide improvement
financing  to existing  properties  and to purchase ten medical and other office
buildings  totaling  approximately  $92.1 million.  The Company  intends to fund
these  commitments with a combination of cash on hand,  amounts  available under
its existing credit facility,  proceeds of mortgage prepayments,  if any, and/or
proceeds  of  other  financings  such as the  possible  issuance  of  additional
securities.  In January and February 1998, the Company  acquired ten medical and
other office buildings for $81.6 million with available cash and by borrowing on
the Company's revolving bank credit facility.

     During February 1998, the Company issued  5,495,776  common shares,  issued
additional  Notes totaling $50.0 million and issued 6.7% unsecured  Senior Notes
due 2005 totaling  $100.0  million.  Net proceeds of $253.3 million were used to
repay amounts  outstanding under the Company's revolving credit facility and for
general business purposes.

     The Company  continues to seek new  investments to expand and diversify its
portfolio of real estate.  The Company believes that the transactions  described
above will  improve  the  security  of its future  funds from  operations,  cash
available  for  distribution,  and  dividends.  As of  December  31,  1997,  the
Company's debt as a percentage of total book  capitalization  was  approximately
38%. There can be no assurances that debt or equity  financing will be available
to fund the Company's existing commitments or its future growth, but the Company
expects such financing will be available.

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations

Impact of Inflation

     Management  believes  that the  Company  may not be  adversely  affected by
modest  inflation.  In the real estate market,  inflation  tends to increase the
value of the Company's  underlying  real estate which may be realized at the end
of fixed rent terms. In the health care and hotel industries,  inflation usually
increases the lessees'  revenues,  thereby  increasing the Company's  additional
rent or interest.

Certain Considerations

     The  discussion  and  analysis of the  Company's  financial  condition  and
results of  operations  requires  the  Company  to make  certain  estimates  and
assumptions and contains certain statements of the Company's beliefs,  intent or
expectation concerning  projections,  plans, future events and performance.  The
estimates,  assumptions and statements,  such as those relating to the Company's
ability to expand its portfolio,  performance of its assets,  the ability to pay
dividends from FFO, its tax status as a "real estate  investment  trust" and the
ability to access capital  markets  depends upon various  factors over which the
Company  and/or the  Company's  lessees  have or may have limited or no control.
Those factors include,  without limitation,  the status of the economy,  capital
markets  (including  prevailing  interest rates)  compliance with and changes to
regulations  within the health care industry,  competition,  changes in federal,
state and local  legislation  and other factors.  The Company cannot predict the
impact  of these  factors,  if any.  However,  these  factors  could  cause  the
Company's  actual  results for  subsequent  periods to be  different  from those
stated,  estimated or assumed in this  discussion  and analysis of the Company's
financial  condition and results of  operations.  The Company  believes that its
estimates and assumptions are reasonable and prudent at this time.

     The  Company's  Year 2000  initiative  is being  managed by the  Company to
minimize  any  adverse  effect  on  the  Company's  business  operations  and is
scheduled  to be  completed  in 1999.  While the Company  believes  its planning
efforts  are  adequate  to  address  its Year  2000  concerns,  there  can be no
guarantee that the systems of other companies on which the Company's systems and
operations rely will be converted on a timely basis and will not have a material
effect on the Company.  The cost of the Year 2000 initiatives is not expected to
be material to the Company's results of operations or financial position.

                         REPORT OF INDEPENDENT AUDITORS


To the Trustees and Shareholders of Health and Retirement Properties Trust

We have  audited  the  accompanying  consolidated  balance  sheets of Health and
Retirement  Properties  Trust as of December 31, 1997 and 1996,  and the related
consolidated statements of income, shareholders' equity, 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.  The financial  statements of Hospitality  Properties  Trust (a real
estate  investment  trust in which the Company has a 10.3% and 14.9% interest as
of December 31, 1997 and 1996, respectively) have been audited by other auditors
whose  report  has  been  furnished  to  us;  insofar  as  our  opinion  on  the
consolidated  financial  statements  relates to data  included  for  Hospitality
Properties Trust, it is based solely on their report.

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 and the report of other auditors provide a reasonable
basis for our opinion.

In our  opinion,  based on our  audits  and the  report of other  auditors,  the
consolidated  financial  statements  referred to above  present  fairly,  in all
material respects,  the financial  position of Health and Retirement  Properties
Trust at  December  31,  1997 and  1996,  and the  consolidated  results  of its
operations  and its cash flows for each of the three  years in the period  ended
December 31, 1997, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1.  Organization

     Health and Retirement  Properties  Trust, a Maryland real estate investment
trust (the  "Company"),  was  organized  on October 9, 1986.  As of December 31,
1997, the Company had investments in 217 properties located in 33 states and the
District of Columbia.  The properties  include 92 long-term care facilities,  58
medical  office and other office  buildings and clinics,  29  government  office
buildings,  26 retirement and assisted  living  communities and 12 nursing homes
with subacute  services.  In addition,  at December 31, 1997,  the Company had a
10.3% equity investment in Hospitality Properties Trust ("HPT"). At December 31,
1997, HPT owned 119 hotels in 30 states.

Note 2.  Summary of Significant Accounting Policies

     Basis of Presentation.  The consolidated  financial  statements include the
Company's investment in 100% owned subsidiaries. The Company's investment in 50%
or  less  owned  companies  is  accounted  for  using  the  equity  method.  All
inter-company  transactions  have been  eliminated.  The Company uses the income
statement method to account for issuance of common shares of beneficial interest
by HPT. Under this method,  gains and losses reflecting  changes in the value of
the Company's  ownership stake on issuance of stock by HPT are recognized in the
Company's income statement.

     Real Estate Property and Mortgage  Investments.  Real estate properties and
mortgages  are  recorded at cost.  Depreciation  on real estate  investments  is
provided for on a straight-line basis over the estimated useful lives ranging up
to 40 years. Impairment losses on investments are recognized where indicators of
impairment are present and the  undiscounted  cash flow (net  realizable  value)
estimated  to be  generated  by the  Company's  investments  are  less  than the
carrying amount of such  investments.  The determination of net realizable value
includes  consideration  of many factors  including income to be earned from the
investment, holding costs (exclusive of interest), estimated selling prices, and
prevailing economic and market conditions.

     Cash and Cash Equivalents. Cash, over-night repurchase agreements and short
term investments with maturities of three months or less at the date of purchase
are carried at cost plus accrued interest.

     Deferred  Interest  and Finance  Costs.  Costs  incurred to secure  certain
borrowings are capitalized and amortized over the terms of the respective loans.
Accumulated amortization at December 31, 1997 and 1996 was $1.8 million and $1.2
million, respectively.

     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.

     Earnings  Per Common  Share.  Basic  earnings  per common share is computed
using the weighted average number of shares  outstanding  during the period.  At
December 31, 1997 and 1996,  $211.7  million and $227.8  million of  convertible
securities  were  convertible  into 11.8 million and 12.7 million  shares of the
Company,  respectively.  Basic  earnings per share equals  diluted  earnings per
share as the effect of these convertible  securities is anti-dilutive to diluted
earnings per share.  Supplemental  income per share for the years ended December
31, 1997,  and 1995 was $1.25 and $1.11,  respectively,  based on the assumption
that the issuance of shares in the Company's  public  offerings  during 1997 and
1995, and the related  repayment of outstanding bank  borrowings,  took place at
the beginning of each year.

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

     Federal Income Taxes.  The Company is 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.

     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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     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") and Statement No. 131  "Disclosures  About Segments of an Enterprise
and Related  Information"  ("FAS 131"). FAS 128 and FAS 129 were adopted for the
Company's 1997 financial  statements.  The adoption of each of these  statements
had no impact on the Company's financial statements. FAS 130 and FAS 131 must be
adopted for the Company's 1998  financial  statements.  The Company  anticipates
that  FAS 130 and  FAS 131  will  have  no  impact  on the  Company's  financial
condition or results of operations.
 
Note 3. Real Estate Properties

     In February 1997,  the Company  agreed to acquire 30 office  buildings (the
"Government  Properties")  leased  to  various  agencies  of the  United  States
Government  through the  acquisition of Government  Properties  Investors,  Inc.
("GPI").  The acquisition was accounted for as a purchase and the net assets and
results  of  operations  have  been  included  in  the  consolidated   financial
statements  since the date of acquisition.  As of December 31, 1997, the Company
completed  the purchase of 29 of the  Government  Properties  for  approximately
$439.5 million and elected not to acquire one of the Government Properties.  The
acquisition of the Government  Properties was funded, in part, with the proceeds
from the issuance of the Company's  common shares pursuant to a public offering,
the issuance of 4,019,429  common  shares of the Company in a private  placement
and the assumption of $27.6 million of debt.

     In September 1997, the Company sold 14 nursing properties for $33.5 million
and purchased  three  nursing  properties  which were  mortgage  financed by the
Company  for  $15.7  million.  In  connection  with  the  sale  of  the  nursing
properties, the company recognized a gain of $2.9 million.

     Also during the year ended  December  31,  1997,  the Company  acquired one
retirement  community,  22 medical  and other  office  buildings  and 20 medical
clinics for an aggregate amount of  approximately  $539.1 million in 13 separate
transactions.  In  addition,  the Company  funded  improvements  to its existing
properties of approximately $4.3 million.

     In January and February 1998, the Company  acquired seven medical and other
office  buildings for $71.6  million.  In addition,  the Company sold one of the
Government  Properties  for $5.7 million.  No gain or loss was recognized on the
sale of this property.

     The Company's real estate properties are leased on a gross lease,  modified
gross lease or triple net lease basis,  pursuant to  noncancellable,  fixed term
operating leases expiring from 1998 to 2022. Generally, the Company's triple net
leases  to  a  single  tenant  are  cross-collateralized,   cross-defaulted  and
cross-guaranteed  and  generally  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 Company's
gross leases and modified  gross leases  require the Company to provide  certain
property management services.  The Government Properties and certain medical and
other office properties owned by the Company are managed by M&P Partners Limited
Partnership ("M&P"), an affiliate of the Company.

     The future  minimum lease payments to be received by the Company during the
current terms of the leases as of December 31, 1997,  are  approximately  $223.6
million in 1998,  $216.5 million in 1999, $208.8 million in 2000, $199.1 million
in 2001, $185.4 million in 2002 and $1.4 billion thereafter.

common shares in connection with the purchase of real estate.

     In January 1998, the Company  declared a dividend of $.37 to be distributed

1995 were $1.45, $1.41 and $1.37, respectively.

     The  Company  adopted a  Shareholders  Rights Plan  ("Rights").  Each Right
entitles the holder to purchase or to receive  securities or other assets of the
Company, upon the occurrence of certain events. The Rights expire on October 17,
2004 and are redeemable at the Company's option at any time.

     The Company has reserved  1,000,000  shares of the Company's  common shares
under the terms of the 1992  Incentive  Share  Award  Plan (the  "Award  Plan").
During 1997, 1996 and 1995, 9,500,  7,250 and 8,500 shares,  respectively,  were

The medical and other  office  buildings  were  purchased  for $71.6  million in
January and February 1998.

     The Company is involved in  litigation  with a former  tenant.  The amounts
claimed  against the Company are material.  The Company intends to defend itself
and to pursue its claims and rights  against the former  tenant.  The outcome of
this pending litigation cannot be predicted.

     Lessee's and  mortgagors' of the Company's  long-term  care  facilities and
nursing  facilities are dependent upon  compliance with  regulations  within the
health care industry.  Future changes to these regulations may affect the health
care  industry,  the  Company's  lessees and  mortgagors  and, as a result,  the
Company.

Note 8.  Transactions with Affiliates

     As of January 1, 1998,  the Company  entered  into an  agreement  with REIT
Management  and Research,  Inc.  ("RMR"),  an affiliate of the Company,  and the
Advisor. RMR provides investment,  management,  property management services for
some of the recently acquired Government Properties and medical and other office
buildings  and  administrative  services to the Company.  During the three years
ended  December 31, 1997,  such services were provided by the Advisor and M&P on
similar terms.  RMR is owned by Gerard M. Martin and Barry M. Portnoy,  who also
serve as Managing Trustees of the Company.  RMR is compensated at an annual rate
equal to .7% of the Company's  real estate  investments up to $250.0 million and
 .5% of such investments  thereafter plus property management fees equal to three
percent of gross rents from the managed  properties.  RMR is also entitled to an
incentive fee comprised of restricted shares of the Company's common stock based
on a formula.  Incentive  fees paid to the Advisor for the years ended  December
31, 1997, 1996 and 1995 were $1.0 million, $0.6 million and $0.6 million,  which
represent  approximately 52,316, 32,846 and 35,560 common shares,  respectively.
At December 31, 1997, the Advisor owned 1,082,056 common shares.
