         and/or  Warrants  (collectively,   the  "Offered  Securities")  covered
         hereby. Offered Securities registered hereunder may be sold separately,

         of Debt Securities,  Preferred Shares, Depositary Shares, Common Shares

         Registrant of the securities registered hereunder.

(4)      Estimated  solely for the purpose of calculating the  registration  fee
         pursuant  to Rule  457(o).  In no  event  will  the  aggregate  initial
         offering price of the Debt  Securities,  Preferred  Shares,  Depositary
         Shares,  Common  Shares and  Warrants  issued  under this  Registration
         Statement exceed  $750,000,000 or the equivalent thereof in one or more
         foreign or composite currencies.

(5)      No separate  consideration  will be received  for (i) Debt  Securities,
         Common Shares,  Preferred  Shares or Depositary  Shares that are issued
         upon  conversion  of Debt  Securities,  Preferred  Shares or Depositary
         Shares or (ii) Debt  Securities,  Common  Shares,  Preferred  Shares or
         Depositary Shares that are issued upon exercise of Warrants  registered
         hereby.

(6)      If any such Debt  Securities are issued at an original issue  discount,
         then the offering  price shall be in such greater  principal  amount as
         shall  result  in  an  aggregate   initial  offering  price  of  up  to
         $750,000,000.

(7)      The aggregate amount of Common Shares  registered  hereunder is limited
         to that which is permissible  under Rule 415(a)(4) under the Securities
         Act of 1933, as amended.

         the Securities Act of 1933, as amended.

(9)      Pursuant  to  Rule  429(a)  of the  rules  and  regulations  under  the
         Securities  Act of 1933, as amended,  $33,400,000  in Debt  Securities,
         Common Shares of Beneficial  Interest,  Preferred  Shares of Beneficial
         Interest and Common Share  Warrants are being carried  forward from the
         Company's Registration  Statement on Form S-3 (File No. 33-53173),  and

HPT owned and leased or had  agreements  to acquire and lease an aggregate of 82
hotels located in 26 states.  Excluding its investment in HPT, approximately 70%
of the Company's total  investments as of such date were in properties leased to
or operated by 10 public companies, and approximately 90% of the Company's total
investments were in retirement  communities,  assisted living centers, long term
care facilities and other income producing healthcare related properties.
    

                                 USE OF PROCEEDS

     Unless otherwise  described in the applicable  Prospectus  Supplement,  the
Company intends to use the net proceeds from the sale of the Offered  Securities
for general  trust  purposes,  which may include  the  acquisition  of, or other
investments in, retirement communities, assisted living centers, nursing home or
other long term care facilities or other healthcare related properties,  and the
repayment  of  indebtedness  outstanding  at  such  time  or to  reduce  amounts
outstanding  under the Company's  credit  facility.  Pending  utilization as set
forth  above,  the  proceeds  from the sale of the  Offered  Securities  will be
invested in short term investments, including repurchase agreements.
Such investments may not be investment grade.

                       RATIO OF EARNINGS TO FIXED CHARGES

     The  following  table  sets  forth  the  Company's  consolidated  ratios of
earnings to fixed charges for the periods indicated:

</TABLE>


     The ratios of earnings to fixed  charges  presented  above were computed by
dividing the Company's  earnings by fixed  charges.  For this purpose,  earnings
have been calculated by adding fixed charges (excluding capitalized interest) to
income  before  income  taxes,  extraordinary  items  and  gain  or  loss on the
disposition of real property.  Fixed charges consist of interest costs,  whether
expensed or  capitalized,  the  interest  component  of rental  income,  if any,
amortization of debt discounts and deferred financing costs, whether expensed or
capitalized.  To  date,  the  Company  has  not  issued  any  Preferred  Shares;
therefore,  the ratio of earnings to combined fixed charges and Preferred Shares
distributions  are the same as the ratios of earnings to fixed charges presented
above.

                         DESCRIPTION OF DEBT SECURITIES

     The  Debt  Securities  will be  issued  under  one or more  indentures  (an
"Indenture")  between the Company and a trustee (an  "Indenture  Trustee").  Any
Indenture will be subject to, and governed by, the Trust  Indenture Act of 1939,
as amended (the "TIA"). The statements made hereunder relating to any Indentures
and the Debt  Securities  to be  issued  thereunder  are  summaries  of  certain
anticipated provisions thereof and do not purport to be complete and are subject
to, and are qualified in their  entirety by reference to, all  provisions of the
Indentures and such Debt Securities.


                                        1

<PAGE>


General

     The Debt  Securities will be direct,  unsecured  obligations of the Company
and will rank equally with all other unsecured and  unsubordinated  indebtedness
of the Company (the "Senior  Securities"),  or, if so provided in the applicable
Prospectus  Supplement,  will be  subordinated  in right of payment to the prior
payment in full of other Debt  Securities or other  indebtedness  of the Company
("Subordinated Securities").  See "--Subordination".  The Debt Securities may be
issued without limit as to aggregate principal amount, in one or more series, in
each case as established  from time to time in or pursuant to authority  granted
by a resolution of the Board of Trustees of the Company (the  "Trustees")  or as
established in one or more indentures  supplemental  to any Indenture.  All Debt
Securities  of 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
of the  Debt  Securities  of such  series,  for  issuances  of  additional  Debt
Securities of such series.

     It is anticipated that any Indenture will provide that the Company may, but
need  not,  designate  more than one  Indenture  Trustee  thereunder,  each with
respect to one or more series of Debt  Securities.  Any Indenture  Trustee under
any  Indenture  may resign or be removed  with  respect to one or more series of
Debt Securities,  and a successor Indenture Trustee may be appointed to act with
respect  to such  series.  In the event that two or more  persons  are acting as
Indenture Trustee with respect to different series of Debt Securities, each such
Indenture  Trustee shall be a trustee of a trust under the applicable  Indenture
separate and apart from the trust  administered by any other Indenture  Trustee,
and, except as otherwise  indicated  herein,  any action  described herein to be
taken by the Indenture  Trustee may be taken by each such Indenture Trustee with
respect to, and only with respect to, the one or more series of Debt  Securities
for which it is Indenture Trustee under the applicable Indenture.

     Reference is made to the  Prospectus  Supplement  relating to the series of
Debt Securities being offered for the specific terms thereof,  including,  where
applicable, the following:

     (1)  the title of such Debt Securities and whether such Debt Securities are
          Senior Securities or Subordinated Securities;

     (2)  the aggregate  principal  amount of such Debt Securities and any limit
          on such aggregate principal amount;

     (3) the  percentage of the principal  amount at which such Debt  Securities
         will be issued and, if other than the  principal  amount  thereof,  the
         portion of the principal  amount  thereof  payable upon  declaration of
         acceleration of the maturity thereof, or (if applicable) the portion of
         the principal amount of such Debt Securities  which is convertible,  or
         the method by which any such portion shall be determined;

   
     (4) if   convertible,   the  terms  on  which  such  Debt   Securities  are
         convertible,  including  the initial  conversion  price or rate and the
         conversion  period  and, in  connection  with the  preservation  of the
         Company's status as a REIT, any applicable limitations on the ownership
         or  transferability  of the securities  into which such Debt Securities
         are convertible;
    

     (5) the date or dates, or the method for determining such date or dates, on
         which the principal of such Debt Securities will be payable;

     (6) the rate or rates  (which may be fixed or  variable),  or the method by
         which  such  rate or rates  shall be  determined,  at which  such  Debt
         Securities will bear interest, if any;


                                        2

<PAGE>



     (7) the date or dates,  or the method for  determining  such date or dates,
         from  which  any  interest  will  accrue,  the  dates on which any such
         interest will be payable,  the record dates for such  interest  payment
         dates,  or the method by which any such date shall be  determined,  the
         person to whom such interest shall be payable, and the basis upon which
         interest shall be calculated if other than that of a 360-day year of 12
         months consisting of 30 days each;

   
     (8) the place or places  where the  principal  of, any premium and interest
         on,  and any  additional  amounts  payable  in  respect  of  such  Debt

         Company is to have such an option;

     (10) the  obligation,  if any, of the Company to redeem,  repay or purchase
          such  Debt  Securities  pursuant  to any  sinking  fund  or  analogous
          provision  or at the  option of a holder  thereof,  and the  period or
          periods  within which,  the price or prices at which and the terms and
          conditions upon which such Debt Securities will be redeemed, repaid or
          purchased, as a whole or in part, pursuant to such obligation;

     (11) if other than U.S.  dollars,  the currency or currencies in which such
          Debt Securities are  denominated  and payable,  which may be a foreign
          currency  or units of two or more  foreign  currencies  or a composite
          currency or currencies, and the terms and conditions relating thereto;

     (12) if the  principal  of or  premium,  if any,  or  interest on such Debt
          Securities  is to be  payable,  at the  election  of the  Company or a
          holder thereof, in one or more currencies or currency units other than
          that or those in which such Debt  Securities are stated to be payable,
          the  currency,  currencies  or currency  units in which payment of the
          principal of and premium,  if any, and interest on Debt  Securities of
          such series as to which such  election  is made shall be payable,  and
          the periods within which and the terms and conditions  upon which such
          election is to be made;

     (13) whether the amount of payments of principal of (and  premium,  if any)
          or interest,  if any, on such Debt  Securities may be determined  with
          reference to an index,  formula or other method (which index,  formula
          or method  may,  but need  not,  be based on a  currency,  currencies,
          currency unit or units or composite  currency or  currencies)  and the
          manner in which such amounts shall be determined;

   
     (14) the events of default or  covenants  of such Debt  Securities,  to the
          extent  different from or in addition to those described  herein,  and
          any  provisions  granting  special  rights to the holders of such Debt
          Securities upon the occurrence of events  specified in such Prospectus
          Supplement;
    

     (15) whether such Debt  Securities  will be issued in  certificated  and/or
          book-entry form;

     (16) whether such Debt Securities will be in registered or bearer form and,
          if in registered form, the denominations  thereof if other than $1,000
          and  any  integral  multiple  thereof  and,  if in  bearer  form,  the
          denominations thereof and terms and conditions relating thereto;

     (17) whether any of such Debt  Securities  are to be issuable in  permanent
          global  form  (a  "Global   Security")  and,  if  so,  the  terms  and
          conditions,  if any, upon which  interests in such Debt  Securities in
          global form may be exchanged,  in whole or in part, for the individual
          Debt Securities represented thereby;

                                        3

     (18) the applicability,  if any, of the defeasance and covenant  defeasance
          provisions described herein or any modification thereof;

     (19) if such Debt  Securities  are to be issued  upon the  exercise of debt
          warrants,  the time,  manner and place for such Debt  Securities to be
          authenticated and delivered;

     (20) whether and under what  circumstances  the Company will pay additional
          amounts on such Debt  Securities in respect of any tax,  assessment or
          governmental  charge  and, if so,  whether  the Company  will have the
          option to redeem such Debt  Securities in lieu of making such payment;
          and

     (21) any other terms of such Debt Securities.

     The Debt Securities may provide for less than the entire  principal  amount
thereof to be payable upon  declaration of acceleration of the maturity  thereof
("Original Issue Discount Securities"). If material or applicable,  special U.S.
federal income tax, accounting and other  considerations  applicable to Original
Issue  Discount  Securities  will  be  described  in the  applicable  Prospectus
Supplement.

     Except as described under  "--Merger,  Consolidation  or Sale" or as may be
set forth in any Prospectus Supplement,  an Indenture will not contain any other
provisions that would limit the ability of the Company to incur  indebtedness or
that would afford  holders of the Debt  Securities  protection in the event of a
highly  leveraged  or  similar  transaction  involving  the  Company.   However,
restrictions on ownership and transfers of the Company's capital stock, designed
to  preserve  its  status as a REIT,  may act to  prevent  or hinder a change of
control.   Reference  is  made  to  the  applicable  Prospectus  Supplement  for
information with respect to any deletions from, modifications of or additions to
the events of default or  covenants  that are  described  below,  including  any
addition  of a  covenant  or other  provisions  providing  event risk or similar
protection.

Denominations, Interest, Registration and Transfer

     Unless otherwise  described in the applicable  Prospectus  Supplement,  the
Debt  Securities  of any  series  which are  registered  securities,  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.

     Unless otherwise  specified in the applicable  Prospectus  Supplement,  the
principal of (and premium, if any) and interest on any series of Debt Securities
will  be  payable  at the  corporate  trust  office  of the  Indenture  Trustee,
initially at the address  which will be set forth in the  applicable  Prospectus
Supplement, provided that, at the option of the Company, payment of interest may
be made by check  mailed to the  address  of the person  entitled  thereto as it
appears in the  applicable  register or by wire transfer of funds to such person
at an account maintained within the United States.

     Any  interest  not  punctually  paid or duly  provided  for on any interest
payment  date  with  respect  to a Debt  Security  ("Defaulted  Interest")  will
forthwith  cease to be payable to the holder on the  applicable  regular  record
date and may either be paid to the person in whose  name such Debt  Security  is
registered  at the close of  business  on a special  record  date (the  "Special
Record  Date") for the  payment of such  Defaulted  Interest  to be fixed by the
applicable  Indenture  Trustee,  notice  whereof shall be given to the holder of
such Debt  Security not less than 10 days prior to such Special  Record Date, or
may be paid at any  time in any  other  lawful  manner,  all as more  completely
described in the applicable Indenture.

     Subject to  certain  limitations  imposed  upon Debt  Securities  issued in
book-entry  form,  the Debt  Securities of any series will be  exchangeable  for
other  Debt  Securities  of the same  series and of a like  aggregate  principal
amount and tenor of different  authorized  denominations  upon surrender of such
Debt  Securities  at the  corporate  trust  office of the  applicable  Indenture


                                        4

<PAGE>


Trustee.  In  addition,   subject  to  certain  limitations  imposed  upon  Debt
Securities  issued in book-entry  form, the Debt Securities of any series may be
surrendered for conversion or registration of transfer  thereof at the corporate
trust  office  of  the  applicable   Indenture  Trustee.   Every  Debt  Security
surrendered for  conversion,  registration of transfer or exchange shall be duly
endorsed or accompanied by a written  instrument of transfer.  No service charge
will  be  made  for  any  registration  of  transfer  or  exchange  of any  Debt
Securities,  but the Indenture  Trustee or the Company may require  payment of a
sum  sufficient  to  cover  any tax or  other  governmental  charge  payable  in
connection  therewith.  If the applicable  Prospectus  Supplement  refers to any
transfer agent (in addition to the Indenture  Trustee)  initially  designated by
the Company  with respect to any series of Debt  Securities,  the Company may at
any time rescind the  designation of any such transfer agent or approve a change
in the location  through  which any such  transfer  agent acts,  except that the
Company  will be required to maintain a transfer  agent in each place of payment
for such  series.  The Company  may at any time  designate  additional  transfer
agents with respect to any series of Debt Securities.

     Neither  the  Company nor any  Indenture  Trustee  shall be required to (i)
issue, register the transfer of or exchange Debt Securities of any series during
a period  beginning  at the opening of business 15 days before any  selection of
Debt  Securities  of that  series  to be  redeemed  and  ending  at the close of
business  on (a) if  such  Debt  Securities  are  issuable  only  as  registered
securities,  the day of the mailing of the relevant notice of redemption and (b)
if such Debt Securities are issuable as bearer securities,  the day of the first
publication of the relevant notice of redemption or, if such Debt 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 like  tenor,  provided  that  such
registered security shall be simultaneously  surrendered for redemption, or (iv)
to issue,  register the transfer of or exchange any Debt Security which has been
surrendered  for repayment at the option of the holder,  except the portion,  if
any, of such Debt Security not to be so repaid.

   
Merger, Consolidation or Sale
    

     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  entity,
provided  that (i)  either the  Company  shall be the  continuing  entity or the
successor  entity (if other than the Company)  formed by or  resulting  from any
such  consolidation  or merger or which shall have received the transfer of such
assets shall expressly assume payment of the principal of (and premium,  if any)
and interest on all of the Debt Securities and the due and punctual  performance
and  observance  of  all  of  the  covenants  and  conditions  contained  in any
Indenture; (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 under any Indenture,  and no
event which,  after notice or the lapse of time,  or both,  would become such an
event of default, shall have occurred and be continuing;  and (iii) an officer's
certificate and legal opinion covering such conditions shall be delivered to the
Indenture Trustee.

Certain Covenants

     Existence. Except as permitted under "--Merger, Consolidation or Sale," the
Company  will be  required  to do or cause to be done all  things  necessary  to
preserve  and keep in full  force and  effect its  corporate  existence,  rights
(charter and  statutory) and  franchises;  provided,  however,  that the Company
shall not be required to preserve any right or franchise if it  determines  that
the preservation thereof is no longer desirable in the conduct of its business.

     Provision of Financial  Information.  Whether or not the Company is subject
to Section 13 or 15(d) of the  Exchange  Act,  the Company  will,  to the extent
permitted  under the Exchange Act, file with the Commission the annual  reports,
quarterly reports and other documents which the Company would have been required


                                        5

<PAGE>


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 (i) within 15 days
of each  Required  Filing  Date  (a)  transmit  by mail to all  holders  of Debt
Securities,  as their  names  and  addresses  appear in the  Company's  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  Exchange  Act if the Company
were  subject  to such  Sections,  and (b) file  with the  applicable  Indenture
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  Exchange  Act if the Company were subject to such
Sections,  and (ii) if filing such  documents by the Company with the Commission
is not  permitted  under the Exchange  Act,  promptly  upon written  request and
payment of the  reasonable  cost of duplication  and delivery,  supply copies of
such documents to any prospective holder of Debt Securities.

     Additional Covenants.  Any additional or different covenants of the Company
with  respect  to any  series  of  Debt  Securities  will  be set  forth  in the
Prospectus Supplement relating thereto.

Events of Default, Notice and Waiver

     Each  Indenture  will  provide  that the  following  events are  "Events of
Default" with respect to any series of Debt Securities  issued  thereunder;  (a)
default for 30 days in the payment of any  installment  on any Debt  Security of
such series; (b) default in the payment of the principal of (or premium, if any,
on) any Debt Security of such series at its maturity;  (c) default in making any
sinking  fund  payments as required for any Debt  Security of such  series;  (d)
default in the performance of any other covenant of the Company contained in the
applicable  Indenture  (other than a covenant added to such Indenture solely for
the benefit of a series of Debt  Securities  issued  thereunder  other than such
series),  such default  having  continued  for 60 days after  written  notice as
provided in such Indenture; (e) default in the payment of an aggregate principal
amount  exceeding a specified  dollar amount of any evidence of  indebtedness of
the Company or any  mortgage,  indenture  or other  instrument  under which such
indebtedness is issued or by which such  indebtedness  is secured,  such default
having  occurred after the expiration of any applicable  grace period and having
resulted in the acceleration of the maturity of such  indebtedness,  but only if
such  indebtedness  is not discharged or such  acceleration  is not rescinded or
annulled;  (f) certain events of bankruptcy,  insolvency or  reorganization,  or
court  appointment  of a receiver,  liquidator  or trustee of the Company or any
Significant  Subsidiary  (as  hereinafter  defined)  or any of their  respective
property;  and (g) any  other  event  of  default  provided  with  respect  to a
particular series of Debt Securities.  The term  "Significant  Subsidiary" means
each significant  subsidiary (as defined in Regulation S-X promulgated under the
Securities Act) of the Company.

     If an Event of Default (other than an Event of Default  described in clause
(f) above) under any Indenture with respect to Debt  Securities of any series at
the time  outstanding  occurs  and is  continuing,  then in every  such case the
applicable  Indenture  Trustee or the  holders  of not less than a  majority  in
principal  amount of the outstanding  Debt Securities of that series may declare
the  principal  amount (or, if the Debt  Securities  of that series are Original
Issue Discount Securities or indexed  securities,  such portion of the principal
amount as may be specified in the terms  thereof) of all of the Debt  Securities
of that series to be due and payable  immediately  by written  notice thereof to
the Company (and to the applicable  Indenture  Trustee if given by the holders).
If an Event of Default  described  in clause (f) above with  respect to the Debt
Securities  of any series at the time  outstanding  shall occur,  the  principal
amount of all the Debt  Securities  of that  series (or, in the case of any such
Original Issue Discount Security or other Debt Security,  such specified amount)
will  automatically,  and  without  any action by the  Indenture  Trustee or any
holder of such series of Debt  Securities,  become  immediately due and payable.
However,  at any time after such a declaration of  acceleration  with respect to
Debt Securities of such series (or of all Debt Securities then outstanding under
the  applicable  Indenture,  as the  case may be) has been  made,  but  before a
judgment  or  decree  for  payment  of the money  due has been  obtained  by the
applicable  Indenture  Trustee,  the  holders  of not less  than a  majority  in
principal  amount of outstanding  Debt Securities of such series (or of all Debt
Securities then outstanding under the applicable Indenture,  as the case may be)
may rescind and annul such declaration and its consequences if (i) the Company

                                        6

<PAGE>


shall have deposited with the applicable Indenture Trustee all required payments
of the principal of (and premium, if any) and interest on the Debt Securities of
such series (or of all Debt  Securities  then  outstanding  under the applicable
Indenture,  as the case may be), plus certain fees, expenses,  disbursements and
advances of the applicable  Indenture  Trustee,  and (ii) all Events of Default,
other than the  non-payment  of  accelerated  principal  (or  specified  portion
thereof),  or premium (if any) or interest on the Debt Securities of such series
(or of all Debt Securities then outstanding under the applicable  Indenture,  as
the  case may be) have  been  cured or  waived  as  provided  in the  applicable
Indenture. Each of the Indentures will also provide that the holders of not less
than a majority in principal  amount of the  outstanding  Debt Securities of any
series  (or of  all  Debt  Securities  then  outstanding  under  the  applicable
Indenture,  as the case may be) may waive any past  default with respect to such
series  and  its  consequences,  except  a  default  (i) in the  payment  of the
principal  of (or  premium,  if any) or  interest  on any Debt  Security of such
series or (ii) in respect of a covenant or provision contained in the applicable
Indenture  that cannot be modified or amended  without the consent of the holder
of each outstanding Debt Security affected thereby.

     The  Indenture  Trustee  will be  required to give notice to the holders of
Debt  Securities  within 90 days of a default  under  the  applicable  Indenture
unless  such  default  has been cured or waived;  provided,  however,  that such
Indenture  Trustee  may  withhold  notice to the  holders  of any series of Debt
Securities  of any default with respect to such series  (except a default in the
payment  of the  principal  of (or  premium,  if any) or  interest  on any  Debt
Security of such series or in the payment of any  sinking  fund  installment  in
respect of any Debt Security of such series) if specified  responsible  officers
of such  Indenture  Trustee  consider such  withholding to be in the interest of
such holders.

     Each  Indenture  will  provide  that no holders of Debt  Securities  of any
series may institute any proceedings, judicial or otherwise, with respect to the
Indenture  or for any  remedy  thereunder,  except in the case of failure of the
Indenture  Trustee,  for 60 days, to act after it has received a written request
to institute  proceedings  in respect of an event of default from the holders of
not less than a majority in principal  amount of the outstanding Debt Securities
of such series, as well as an offer of reasonable indemnity. This provision will
not prevent,  however,  any holder of Debt Securities from  instituting suit for
the  enforcement  of  payment  of the  principal  of (and  premium,  if any) and
interest on such Debt Securities at the respective due dates thereof.

     Subject to provisions in the applicable Indenture relating to its duties in
case of default,  no Indenture  Trustee will be under any obligation to exercise
any of its rights or powers under such  Indenture at the request or direction of
any  holders  of any  series of Debt  Securities  then  outstanding  under  such
Indenture,  unless such  holders  shall have  offered to the  Indenture  Trustee
reasonable  security  or  indemnity.  The holders of not less than a majority in
principal  amount of the  outstanding  Debt  Securities of any series (or of all
Debt Securities then outstanding under the applicable Indenture, as the case may
be) shall have the right to direct the time,  method and place of conducting any
proceeding for any remedy available to the applicable  Indenture Trustee,  or of
exercising any trust or power conferred upon such Indenture Trustee.  However, a
Indenture  Trustee may refuse to follow any direction  which is in conflict with
any law or the Indenture,  which may involve such Indenture  Trustee in personal
liability or which may be unduly  prejudicial to the holders of Debt  Securities
of such series not joining therein.

     The Company will be required to deliver to each Indenture  Trustee annually
a  certificate,  signed by one of several  specified  officers  of the  Company,
stating  whether or not such  officer has  knowledge  of any  default  under the
applicable Indenture and, if so, specifying each such default and the nature and
status thereof.

Modification of the Indenture

     Modifications  and  amendments of an Indenture will be permitted to be made
only with the consent of the  holders of not less than a majority  in  principal
amount  of all  outstanding  Debt  Securities  or  series  of  outstanding  Debt
Securities  which are  affected by such  modification  or  amendment;  provided,
however,  that no such modification or amendment may, without the consent of the
holder of each such Debt  Security  affected  thereby,  (i)  change  the  stated
maturity of the principal  of, or any  installment  of interest (or premium,  if


                                        7

<PAGE>


any) on any such Debt Security; (ii) reduce the principal amount of, or the rate
or amount of interest on, or any premium payable on redemption of, any such Debt
Security,  or reduce the  amount of  principal  of an  Original  Issue  Discount
Security that would be due and payable upon  declaration of  acceleration of the
maturity  thereof or would be provable in  bankruptcy,  or adversely  affect any
right of  repayment  of the holder of any such Debt  Security;  (iii) change the
place of payment, or the coin or currency, for payment of principal of, premium,
if any,  or  interest  on any such  Debt  Security;  (iv)  impair  the  right to
institute suit for the enforcement of any payment on or with respect to any such
Debt  Security;  (v) reduce the  above-stated  percentage  of  outstanding  Debt
Securities of any series  necessary to modify or amend the  Indenture,  to waive
compliance with certain  provisions thereof or certain defaults and consequences
thereunder  or to reduce  the  quorum or voting  requirements  set forth in such
Indenture;  or  (vi)  modify  any  of  the  foregoing  provisions  or any of the
provisions relating to the waiver of certain past defaults or certain covenants,
except to increase the required  percentage  to effect such action or to provide
that certain other  provisions may not be modified or waived without the consent
of the holder of such Debt Security.

     Each Indenture will provide that the holders of not less than a majority in
principal  amount of a series of outstanding  Debt  Securities have the right to
waive compliance by the Company with certain  covenants  relating to such series
of Debt Securities in such Indenture.

     Modifications  and  amendments of an Indenture will be permitted to be made
by the Company  and the  applicable  Indenture  Trustee  thereunder  without the
consent of any holder of Debt Securities for any of the following purposes:  (i)
to evidence the  succession  of another  person to the Company as obligor  under
such  Indenture;  (ii) to add to the covenants of the Company for the benefit of
the holders of all or any series of Debt Securities or to surrender any right or
power  conferred  upon the  Company  in such  Indenture;  (iii) to add events of
default for the benefit of the holders of all or any series of Debt  Securities;
(iv) to add or change any provisions of the Indenture to facilitate the issuance
of, or to  liberalize  certain  terms of, Debt  Securities in bearer form, or to
permit or facilitate  the issuance of Debt  Securities in  uncertificated  form,
provided  that such  action  shall not  adversely  affect the  interests  of the
holders  of the Debt  Securities  in any  material  respect;  (v) to  change  or
eliminate  any  provisions  of the  Indenture,  provided that any such change or
elimination  shall  become  effective  only when  there  are no Debt  Securities
outstanding  of any series  created  prior  thereto  which are  entitled  to the
benefit  of such  provision;  (vi) to  secure  the  Debt  Securities;  (vii)  to
establish  the form or terms of Debt  Securities  of any series,  including  the
provisions  and  procedures,  if  applicable,  for the  conversion  of such Debt
Securities  into Common  Shares or Preferred  Shares;  (viii) to provide for the
acceptance of  appointment  by a successor  Indenture  Trustee or facilitate the
administration  of the  trusts  under an  Indenture  by more than one  Indenture
Trustee;  (ix) to cure any ambiguity,  defect or  inconsistency in an Indenture,
provided that such action shall not adversely affect the interests of holders of
Debt Securities of any series in any material respect;  or (x) to supplement any
of the  provisions  of an  Indenture  to  the  extent  necessary  to  permit  or
facilitate  defeasance  and  discharge  of any  series of such Debt  Securities,
provided  that such  action  shall not  adversely  affect the  interests  of the
holders of the Debt Securities of any series in any material respect.

     Each Indenture will provide that in determining  whether the holders of the
requisite principal amount of outstanding Debt Securities of a series have given
any  request,  demand,  authorization,  direction,  notice,  consent  or  waiver
thereunder  or  whether a quorum is  present  at a meeting  of  holders  of Debt
Securities, (i) the principal amount of an Original Issue Discount Security that
shall be deemed to be outstanding  shall be the amount of the principal  thereof
that  would  be due  and  payable  as of the  date of  such  determination  upon
declaration of acceleration of the maturity  thereof,  (ii) the principal amount
of a Debt  Security  denominated  in a  foreign  currency  that  shall be deemed
outstanding  shall be the U.S. dollar  equivalent,  determined on the issue date
for such Debt Security,  of the principal amount (or, in the case of an Original
Issue Discount  Security,  the U.S. dollar  equivalent on the issue date of such
Debt  Security of the amount  determined  as  provided in (i) above),  (iii) the
principal amount of an indexed security that shall be deemed  outstanding  shall
be the  principal  face amount of such  indexed  security at original  issuance,
unless  otherwise  provided  with  respect  to  such  indexed  security  in  the
applicable Indenture, and (iv) Debt Securities owned by the Company or any other
obligor  upon the Debt  Securities  or any  affiliate  of the Company or of such
other obligor shall be disregarded.


                                        8

<PAGE>



     Each  Indentures  will contain  provisions  for  convening  meetings of the
holders of Debt  Securities of a series.  A meeting may be called at any time by
an Indenture Trustee,  and also, upon request,  by the Company or the holders of
at least 25% in principal  amount of the  outstanding  Debt  Securities  of such
series,  in any such case,  upon notice  given as  provided  in such  Indenture.
Except for any  consent  that must be given by the holder of each Debt  Security
affected by certain modifications and amendments of an Indenture, any resolution
presented at a meeting or adjourned meeting duly reconvened at which a quorum is
present may be adopted by the  affirmative  vote of the holders of a majority in
principal  amount of the outstanding  Debt Securities of that series;  provided,
however,  that,  except as referred to above, any resolution with respect to any
request,  demand,  authorization,  direction,  notice,  consent, waiver or other
action  that  may be  made,  given  or  taken  by  the  holders  of a  specified
percentage,  which  is  less  than  a  majority,  in  principal  amount  of  the
outstanding Debt Securities of a series may be adopted at a meeting or adjourned
meeting duly reconvened at which a quorum is present by the affirmative  vote of
the holders of such specified  percentage in principal amount of the outstanding
Debt Securities for that series.  Any resolution passed or decision taken at any
meeting of holders of Debt Securities of any series duly held in accordance with
the applicable  Indenture  will be binding on all holders of Debt  Securities of
that series. The quorum at any meeting called to adopt a resolution,  and at any
reconvened  meeting,  will be persons  holding  or  representing  a majority  in
principal  amount of the  outstanding  Debt  Securities  of a series;  provided,
however,  that if any action is to be taken at such  meeting  with  respect to a
consent or waiver which may be given by the holders of not less than a specified
percentage in principal  amount of the outstanding  Debt Securities of a series,
the persons  holding or  representing  such  specified  percentage  in principal
amount of the  outstanding  Debt  Securities  of such series will  constitute  a
quorum.

     Notwithstanding the foregoing provisions,  each Indenture will provide that
if any action is to be taken at a meeting of holders of Debt  Securities  of any
series with respect to any request, demand,  authorization,  direction,  notice,
consent,  waiver or other action that such Indenture  expressly  provides may be
made,  given or taken by the holders of such  series and one or more  additional
series:  (i) there shall be no minimum quorum  requirement  for such meeting and
(ii) the principal amount of the outstanding Debt 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 such Indenture.

Discharge, Defeasance and Covenant Defeasance

     The Company may discharge  certain  obligations to holders of any series of
Debt Securities that have not already been delivered to the applicable Indenture
Trustee  for  cancellation  and that  either have become due and payable or will
become due and payable within one year (or scheduled for  redemption  within one
year) by irrevocably  depositing with such Indenture Trustee, in trust, funds in
such currency or  currencies,  currency  unit or units or composite  currency or
currencies in which such Debt Securities are payable in an amount  sufficient to
pay the entire indebtedness on such Debt Securities in respect of principal (and
premium,  if any)  and  interest  to the  date of such  deposit  (if  such  Debt
Securities  have become due and payable) or to the stated maturity or redemption
date, as the case may be.

     An  Indenture  may provide  that,  if certain  provisions  thereof are made
applicable  to the  Debt  Securities  of or  within  a  series  pursuant  to the
Indenture,  the Company may elect either (i) to defease and be  discharged  from
any and all  obligations  with respect to such Debt  Securities  (except for the
obligation to pay  additional  amounts,  if any, upon the  occurrence of certain
events of tax,  assessment  or  governmental  charge with respect to payments on
such Debt Securities and the obligations to register the transfer or exchange of
such Debt  Securities,  to replace  temporary or mutilated,  destroyed,  lost or
stolen Debt Securities,  to maintain an office or agency in respect of such Debt
Securities and to hold moneys for payment in trust) ("defeasance") or (ii) to be
released from its obligations with respect to such Debt Securities under certain
sections  of  such  Indenture   (including  the  restrictions   described  under
"--Certain  Covenants")  and,  if  provided  pursuant  to  such  Indenture,  its
obligations with respect to any other covenant,  and any omission to comply with
such  obligations  shall not  constitute  a default or an event of default  with
respect to such Debt Securities ("covenant defeasance"), in either case upon the


                                        9

<PAGE>


irrevocable  deposit by the Company with the applicable  Indenture  Trustee,  in
trust, of an amount,  in such currency or currencies,  currency unit or units of
composite  currency or currencies in which such Debt  Securities  are payable at
stated  maturity,  or  Government  Obligations  (as  defined  below),  or  both,
applicable  to such Debt  Securities  which  through  the  scheduled  payment of
principal and interest,  in accordance with their terms will provide money in an
amount sufficient to pay the principal of (and premium,  if any) and interest on
such Debt  Securities,  and any  mandatory  sinking fund or  analogous  payments
thereon, on the scheduled dates therefor.

     Such a trust may be  established  only if, among other things,  the Company
has  delivered  to the  applicable  Indenture  Trustee an opinion of counsel (as
specified in the  applicable  Indenture)  to the effect that the holders of such
Debt Securities will not recognize income,  gain or loss for U.S. federal income
tax purposes as a result of such  defeasance or covenant  defeasance and will be
subject to U.S.  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  or  covenant
defeasance had not occurred.

     "Government  Obligations" means securities which are (i) direct obligations
of the United  States of  America or the  government  which  issued the  foreign
currency in which the Debt  Securities of a particular  series are payable,  for
the payment of which its full faith and credit is pledged or (ii) obligations of
a person controlled or supervised by and acting as an agency or  instrumentality
of the United  States of America or such  government  which  issued the  foreign
currency in which the Debt  Securities of a particular  series are payable,  the
payment  of which is  unconditionally  guaranteed  as a full  faith  and  credit
obligation by the United States of America or such other  government,  which, in
either case, are not callable or redeemable at the option of the issuer thereof,
and shall also include a depository receipt issued by a bank or trust company as
custodian with respect to any such Government  Obligation or a specific  payment
of interest  on or  principal  of any such  Government  Obligation  held by such
custodian for the account of the holder of a depository  receipt,  provided that
(except  as  required  by law)  such  custodian  is not  authorized  to make any
deduction from the amount payable to the holder of such depository  receipt from
any amount received by the custodian in respect of the Government Obligations or
the specific  payment of interest on or principal of the Government  Obligations
evidenced by such depository receipt.

     Unless otherwise provided in the applicable Prospectus Supplement, if after
the  Company  has  deposited  funds  and/or  Government  Obligations  to  effect
defeasance or covenant defeasance with respect to Debt Securities of any series,
(i) the holder of a Debt Security of such series is entitled to, and does, elect
pursuant  to the  applicable  Indenture  or the terms of such Debt  Security  to
receive  payment in a currency,  currency unit or composite  currency other than
that in which such  deposit has been made in respect of such Debt  Security,  or
(ii) a Conversion  Event (as defined  below)  occurs in respect of the currency,
currency  unit or composite  currency in which such  deposit has been made,  the
indebtedness represented by such Debt Security 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 on such Debt Security as they become due out
of the proceeds yielded by converting the amount so deposited in respect of such
Debt Security into the  currency,  currency unit or composite  currency in which
such  Debt  Security  becomes  payable  as a  result  of such  election  or such
cessation of usage based on the applicable  market  exchange  rate.  "Conversion
Event" means the cessation of use of (i) a currency,  currency unit or composite
currency  both by the  government  of the country which issued such currency and
for  the  settlement  of   transactions  by  a  central  bank  or  other  public
institutions of or within the international banking community, (ii) the ECU both
within the European  Monetary  System and for the settlement of  transactions by
public institutions of or within the European  Communities or (iii) any currency
unit or composite  currency other than the ECU for the purposes for which it was
established.  Unless otherwise provided in the applicable Prospectus Supplement,
all  payments of  principal  of (and  premium,  if any) and interest on any Debt
Security  that is payable in a foreign  currency  that  ceases to be used by its
government of issuance shall be made in U.S. dollars.

     In the event the Company  effects  covenant  defeasance with respect to any
Debt Securities and such Debt Securities are declared due and payable because of
the occurrence of any event of default other than the event of default described
in clause (d) under  "--Events  of Default,  Notice and Waiver"  with respect to
certain sections of the applicable  Indenture (which sections would no longer be
applicable to such Debt Securities) or described in clause (g) under "--Events

                                       10

<PAGE>



of Default,  Notice and Waiver" with  respect to any other  covenant as to which
there has been covenant defeasance,  the amount in such currency,  currency unit
or composite currency in which such Debt Securities are payable,  and Government
Obligations  on deposit with the Trustee,  will be sufficient to pay amounts due
on such Debt  Securities  at the time of their  stated  maturity  but may not be
sufficient  to pay  amounts  due on  such  Debt  Securities  at the  time of the
acceleration  resulting from such event of default.  However,  the Company would
remain liable to make payment of such amounts due at the time of acceleration.

     Notwithstanding the description set forth under "--Subordination" below, in
the  event  that  the  Company  deposits  money  or  Government  Obligations  in
compliance  with the applicable  Indenture in order to defease all or certain of
its  obligations  with  respect to any  Subordinated  Securities,  the moneys or
Government  Obligations  so deposited  will not be subject to the  subordination
provisions of such Indenture and the indebtedness evidenced by such Subordinated
Securities will not be subordinated in right of payment to the holders of senior
indebtedness to the extent of the moneys or Government Obligations so deposited.

     The applicable  Prospectus  Supplement may further describe the provisions,
if any,  permitting  such  defeasance  or  covenant  defeasance,  including  any
modifications  to the  provisions  described  above,  with  respect  to the Debt
Securities of or within a particular series.

Conversion Rights

     The terms and  conditions,  if any,  upon  which  the Debt  Securities  are
convertible  into Common or Preferred Shares will be set forth in the Prospectus
Supplement  relating  thereto.   Such  terms  will  include  whether  such  Debt
Securities are convertible into Common or Preferred Shares, the conversion price
(or manner of  calculation  thereof),  the conversion  period,  provisions as to
whether  conversion  will be at the option of the  holders of the  Company,  the
events requiring an adjustment of the conversion price and provisions  affecting
conversion  in the  event of the  redemption  of such  Debt  Securities  and any
restrictions on conversion,  including  restrictions directed at maintaining the
Company's REIT status.

Subordination

     The terms and conditions,  if any, upon which Subordinated  Securities of a
series  are  subordinated  to  Debt  Securities  of  other  series  or to  other
indebtedness  of the  Company  will be set  forth in the  applicable  Prospectus
Supplement  relating  thereto.  Such terms  will  include a  description  of the
indebtedness ranking senior to such Subordinated Securities, the restrictions on
payments to the holders of such  Subordinated  Securities  while a default  with
respect to such senior indebtedness in continuing, the restrictions,  if any, on
payments to the holders of such  Subordinated  Securities  following an Event of
Default,  and provisions  requiring holders of such  Subordinated  Securities to
remit certain payments to holders of senior indebtedness.

Global Securities

     If  so  set  forth  in  the  applicable  Prospectus  Supplement,  the  Debt
Securities  of a series  may be issued in whole or in part in the form of one or
more  Global  Securities  that  will be  deposited  with,  or on  behalf  of,  a
depositary  identified in the applicable  Prospectus Supplement relating to such
series.  Global Securities may be issued in either registered or bearer form and
in either  temporary or permanent  form.  The specific  terms of the  depositary
arrangement with respect to any such series of Debt Securities will be described
in the related Prospectus Supplement.

                              DESCRIPTION OF SHARES

   
     The Declaration of Trust ("Declaration") authorizes the Company to issue an
aggregate of 150,000,000 million shares of beneficial interest ("Shares") in the
Company,  including (i) 100,000,000 Common Shares, par value $.01 per share, and
(ii) 50,000,000 Preferred Shares, par value $.01 per share. As of March 31, 1996
there  were  66,165,166  million  Shares  outstanding,  all of which are  Common
Shares. At their March, 1996 meeting,  the Trustees approved and recommended for
approval by the Company's  shareholders  an amendment to the  Declaration  which
would  allow the Board of  Trustees  to amend the  Declaration  to  increase  or
decrease  the  authorized  Shares of the  Company  without  the  requirement  of
shareholder  approval.  A vote of shareholders on such approval is on the agenda
for the  adjourned  session of the  Company's  annual  meeting of  shareholders,
scheduled to be held on June 28, 1996,  and no assurance  can be given that such
amendment will be approved.
    

     The  following  descriptions  do not purport to be complete and are subject
to,  and  qualified  in their  entirety  by  reference  to,  the  more  complete
descriptions thereof set forth in the Declaration. Capitalized terms not defined
herein are as defined in the Declaration.

     The  Declaration  authorizes  the Trustees to cause the  issuance,  without
shareholder  approval,  of other classes or series of Preferred Shares from time
to time and to set (or  change,  if the  class  or  series  has been  previously
established)  the  preferences,  conversion  or  other  rights,  voting  powers,
restrictions,   limitations  as  to  dividends,   qualifications  or  terms  and
conditions of redemption of such  Preferred  Shares as are not prohibited by the
Declaration or applicable  law. As of April 1, 1996, the Trustees had created an
authorized  but  unissued  class of  1,000,000  Preferred  Shares  (the  "Junior
Participating Preferred Shares"),  described more fully below under "Description
of Preferred Shares," and no other such class or series of Preferred Shares.

     Except as otherwise determined by the Trustees with respect to any class or
series  of  Preferred  Shares,  all  Shares:  (i) will  participate  equally  in
dividends  payable to shareholders  when, as and if declared by the Trustees and
ratably in net assets  available for distribution to shareholders on liquidation
or dissolution;  (ii) will have one vote per share on all matters submitted to a
vote of the  shareholders,  (iii) will not have cumulative  voting rights in the
election of Trustees;  and (iv) will have no preference,  conversion,  exchange,
sinking fund, redemption rights or preemptive or similar rights.

     Upon issuance in accordance  with the  Declaration,  applicable law and the
terms and conditions described in the related Prospectus Supplement,  the Shares
will be  fully  paid  and  nonassessable.  The  holders  of  Shares  do not have
preemptive  rights with  respect to the issuance of  additional  Shares or other
securities of the Company.

     The authorized but unissued Shares will be available for issuance from time
to time by the Company at the sole  discretion  of its Board of Trustees for any
proper  trust  purpose,   which  could  include   raising   capital,   providing
compensation  or benefits to employees  and others,  paying  stock  dividends or
acquiring  companies,  businesses or  properties.  The issuance of such unissued
Shares  could have the effect of diluting  the earnings per share and book value
per share of currently outstanding Shares.

   
     For certain other  information with respect to the Shares,  see "Limitation
of Liabilities;  Shareholder  Liability" and "Redemption;  Business Combinations
and Control Share Acquisitions" below.
    


                         DESCRIPTION OF PREFERRED SHARES

     The  Declaration  authorizes  the Board of Trustees to cause the  issuance,
without shareholder approval, of classes or series of Preferred Shares from time
to time and to set (or  change,  if the  class  or  series  has been  previously
established)  the  preferences,  conversion  or  other  rights,  voting  powers,
restrictions,   limitations  as  to  dividends,   qualifications  or  terms  and
conditions of redemption of such Preferred Shares that are not prohibited by the
Declaration or applicable law.

     The Trustees have provided for the Junior Participating Preferred Shares as
an authorized but unissued class of 1,000,000  Preferred  Shares.  The rights of
the Junior  Participating  Preferred Shares, when and if issued, are as follows.
The holder of each Junior Participating Preferred Share is entitled to quarterly
dividends in the greater  amount of $5.00 or 100 times the  quarterly  per share
dividend, whether cash or otherwise,  declared upon the Common Shares. Dividends
on the Junior Participating Preferred Shares are cumulative, and upon failure of
the Company to pay such  dividends for six  quarters,  the holders of the Junior
Participating  Preferred  Shares  shall be entitled to elect two  Trustees.  The
holder of each Junior Participating  Preferred Share is entitled to 100 votes on
all matters  submitted to a vote of the shareholders.  The Junior  Participating
Preferred  Shares  have a  preference  of $100.00  per share  upon  liquidation,
dissolution or winding up of the Company. The rights of the Junior Participating
Preferred  Shares are  subject to the  superior  rights of any senior  series or
class of Preferred Shares which the Board of Trustees shall,  from time to time,
authorize and issue.  See "Redemption;  Business  Combinations and Control Share
Acquisitions" below.
    

     The  following  description  of the  Preferred  Shares  sets forth  certain
general terms and  provisions of the  Preferred  Shares to which any  Prospectus
Supplement may relate.  The statements below describing the Preferred Shares are
in all respects  subject to and qualified in their  entirety by reference to the
applicable  provisions of the  Declaration  (including any  applicable  articles
supplementary) and By-Laws.

General

     Subject to limitations prescribed by Maryland law and the Declaration,  the
Trustees are authorized to fix the number of shares  constituting each series of
Preferred  Shares and the  designations  and powers,  preferences  and relative,
participating, optional or other specific rights and qualifications, limitations
or restrictions thereof,  including such provisions as may be desired concerning
voting,  redemption,  dividends,  dissolution  or the  distribution  of  assets,
conversion  or exchange,  and such other  subjects or matters as may be fixed by
resolutions of the Trustees.

     Reference is made to the  Prospectus  Supplement  relating to the Preferred
Shares offered thereby for specific terms, including:

     (1)  the title of such Preferred Shares;

     (2)  the number of shares of such Preferred Shares offered, the liquidation
          preference per share and the offering price of such Preferred Shares;

     (3)  the dividend rate(s), period(s) and/or payment date(s) or method(s) of
          calculation thereof applicable to such Preferred Shares;

     (4)  the  date  from  which  dividends  on  such  Preferred   Shares  shall
          accumulate, if applicable;

     (5)  the  procedures  for any auction  and  remarketing,  if any,  for such
          Preferred Shares;

     (6)  the provision for a sinking fund, if any, for such Preferred Shares;

     (7)  the provision for redemption, if applicable, of such Preferred Shares;

     (8)  any listing of such Preferred Shares on any securities exchange;

   
     (9)  the terms and  conditions,  if  applicable,  upon which such Preferred
          Shares  will be  convertible  into  Common  Shares of the  Company  or
          another series of Offered  Securities,  including the conversion price
          (or manner of calculation thereof);
    


                                       13

     (10) whether  interests in such  Preferred  Shares will be  represented  by
          Depositary Shares as more fully described below under  "Description of
          Depositary Shares";

     (11) any  other  specific  terms,  preferences,   rights,   limitations  or
          restrictions of such Preferred Shares;

     (12) a discussion of federal income tax  considerations  applicable to such
          Preferred Shares;

     (13) the relative  ranking and  preferences of such Preferred  Shares as to
          dividend rights and rights upon liquidation, dissolution or winding up
          of the affairs of the Company;

     (14) any limitations on issuance of any series of Preferred  Shares ranking
          senior to or on a parity  with such series of  Preferred  Shares as to
          dividend rights and rights upon liquidation, dissolution or winding up
          of the affairs of the Company; and

     (15) any limitations on direct or beneficial  ownership and restrictions on
          transfer, in each case as may be appropriate to preserve the status of
          the Company as a REIT.

   
     As described under "Description of Depositary  Shares," the Company may, at
its option,  elect to offer Depositary  Shares evidenced by depositary  receipts
("Depositary  Receipts"),   each  representing  a  fractional  interest  (to  be
specified in the Prospectus  Supplement relating to the particular series of the
Preferred  Shares) in a share of the particular  series of the Preferred  Shares
issued and deposited with a Depositary (as defined below).
    

Rank

     Unless otherwise determined by the Trustees and specified in the applicable
Prospectus  Supplement,  it is expected  that the  Preferred  Shares will,  with
respect to dividend rights and rights upon  liquidation,  dissolution or winding
up of the  Company,  rank (i)  senior to all  Common  Shares,  and to all equity
securities  ranking junior to such Preferred  Shares;  (ii) on a parity with all
equity securities issued by the Company the terms of which specifically  provide
that such equity  securities  rank on a parity with the  Preferred  Shares;  and
(iii) junior to all equity  securities  issued by the Company the terms of which
specifically  provide that such equity  securities  rank senior to the Preferred
Shares.

Dividends

     Holders of  Preferred  Shares of each series  shall be entitled to receive,
when, as and if declared by the Trustees,  out of assets of the Company  legally
available for payment, cash dividends at such rates and on such dates as will be
set forth in the applicable Prospectus  Supplement.  Each such dividend shall be
payable to holders of record as they appear on the stock  transfer  books of the
Company (or, if applicable,  on the records of the Depositary  referred to below
under "Description of Depositary Shares") on such record dates as shall be fixed
by the Trustees.

   
     Dividends  on any  series of the  Preferred  Shares  may be  cumulative  or
noncumulative,  as provided in the applicable Prospectus Supplement.  Dividends,
if  cumulative,  will be  cumulative  from and  after  the date set forth in the
applicable  Prospectus  Supplement.  If the Trustees  fail to declare a dividend
payable on a dividend  payment  date on any series of the  Preferred  Shares for
which  dividends  are  noncumulative,  then the  holders  of such  series of the
Preferred  Shares  will have no right to  receive a  dividend  in respect of the
dividend period ending on such dividend  payment date, and the Company will have
no  obligation  to pay the  dividend  accrued  for such  period,  whether or not
dividends on such series are  declared  payable on any future  dividend  payment
date.
    

     If Preferred Shares of any series are outstanding,  no full dividends shall
be  declared  or paid or set apart for  payment on the  Preferred  Shares of the
Company of any other series ranking, as to dividends, on a parity with or junior
to the Preferred  Shares of such series for any period unless (i) if such series


                                       14

<PAGE>


of Preferred Shares has a cumulative  dividend,  full cumulative  dividends have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment  thereof set apart for such payment on the  Preferred  Shares of
such series for all past dividend  periods and the then current  dividend period
or (ii) if such series of Preferred Shares does not have a cumulative  dividend,
full   dividends   for  the  then   current   dividend   period   have  been  or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment  thereof  set apart for such  payment  on the  Preferred  Shares of such
series.  When  dividends are not paid in full (or a sum sufficient for such full
payment is not so set  apart)  upon the  Preferred  Shares of any series and the
shares  of any  other  series  of  Preferred  Shares  ranking  on a parity as to
dividends with the Preferred Shares of such series,  all dividends declared upon
Preferred  Shares of such series and any other series of Preferred  Shares shall
in all cases bear to each other the same ratio that accrued  dividends per share
on the Preferred Shares of such series (which shall not include any accumulation
in respect of unpaid  dividends  for prior  dividend  periods if such  Preferred
Shares do not have a  cumulative  dividend)  and such other  series of Preferred
Shares bear to each other.  No  interest,  or sum of money in lieu of  interest,
shall be payable in respect of any  dividend  payment or payments  on  Preferred
Shares of such series which may be in arrears.

     Except as provided in the immediately  preceding  paragraph,  unless (i) if
such series of  Preferred  Shares has a  cumulative  dividend,  full  cumulative
dividends on the Preferred Shares of such series have been or  contemporaneously
are declared and paid or declared and a sum sufficient for the repayment thereof
set  apart  for  payment  for all past  dividend  periods  and the then  current
dividend  period,  and (ii) if such series of  Preferred  Shares does not have a
cumulative dividend,  full dividends on the Preferred Shares of such series have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment  thereof set apart for  payment  for the then  current  dividend
period, no dividends (other than in Common Shares or other capital stock ranking
junior  to the  Preferred  Shares  of  such  series  as to  dividends  and  upon
liquidation)  shall  be  declared  or paid or set  aside  for  payment  or other
distribution  shall be  declared  or made  upon the  Common  Shares or any other
capital stock of the Company ranking junior to or on a parity with the Preferred
Shares of such series as to dividends or upon liquidation,  nor shall any Common
Shares or any  other  capital  stock of the  Company  ranking  junior to or on a
parity  with  the  Preferred  Shares  of such  series  as to  dividends  or upon
liquidation be redeemed,  purchased or otherwise  acquired for any consideration
(or any  moneys  be  paid  to or  made  available  for a  sinking  fund  for the
redemption of any shares of any such stock) by the Company (except by conversion
into or exchange for other  capital stock of the Company  ranking  junior to the
Preferred  Shares of such series as to dividends and upon liquidation and except
pursuant to certain pro rata offers to purchase or a  concurrent  redemption  of
all, or a pro rata portion of, the outstanding shares of the Preferred Shares of
such series and any other  series of Preferred  Shares  ranking on a parity with
such series as to dividends and liquidation).

     Any dividend  payment made on shares of a series of Preferred  Shares shall
first be credited  against the  earliest  accrued but unpaid  dividend  due with
respect to shares of such series which remains payable.

Redemption

     If so provided  in the  applicable  Prospectus  Supplement,  the  Preferred
Shares will be subject to mandatory  redemption  or  redemption at the option of
the Company,  as a whole or in part,  in each case upon the terms,  at the times
and at the redemption prices set forth in such Prospectus Supplement.

     The Prospectus  Supplement relating to a series of Preferred Shares that is
subject to mandatory redemption will specify the number of such Preferred Shares
that shall be redeemed by the Company in each year commencing after a date to be
specified,  at a redemption  price per share to be  specified,  together with an
amount equal to all accrued and unpaid  dividends  thereon  (which shall not, if
such  Preferred  Shares  does  not  have  a  cumulative  dividend,  include  any
accumulation in respect of unpaid  dividends for prior dividend  periods) to the
date of  redemption.  The  redemption  price  may be  payable  in cash or  other
property,  as  specified  in  the  applicable  Prospectus  Supplement.   If  the
redemption price for Preferred Shares of any series is payable only from the net
proceeds of the  issuance  of capital  stock of the  Company,  the terms of such
Preferred  Shares may provide  that,  if no such  capital  stock shall have been
issued or to the extent the net proceeds from any issuance are insufficient to

                                       15

<PAGE>



pay in full the aggregate redemption price then due, such Preferred Shares shall
automatically and mandatorily be converted into shares of the applicable capital
stock  of  the  Company  pursuant  to  conversion  provisions  specified  in the
applicable Prospectus Supplement.

     Notwithstanding  the  foregoing,  unless  (i) if such  series of  Preferred
Shares has a cumulative dividend, full cumulative dividends on all shares of any
series of Preferred Shares shall have been or contemporaneously are declared and
paid or declared  and a sum  sufficient  for the  payment  thereof set apart for
payment for all past dividend periods and the then current dividend period,  and
(ii) if such series of  Preferred  Shares does not have a  cumulative  dividend,
full   dividends   on  the   Preferred   Shares  of  any  series  have  been  or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for payment for the then current dividend  period,  no
shares  of  any  series  of  Preferred  Shares  shall  be  redeemed  unless  all
outstanding  Preferred  Shares  of  such  series  are  simultaneously  redeemed;
provided,  however,  that the  foregoing  shall  not  prevent  the  purchase  or
acquisition  of  Preferred  Shares of such  series  pursuant  to a  purchase  or
exchange  offer made on the same terms to holders of all  outstanding  Preferred
Shares of such series,  and, unless (i) if such series of Preferred Shares has a
cumulative dividend,  full cumulative dividends on all outstanding shares of any
series of Preferred Shares have been or contemporaneously  are declared and paid
or declared and a sum sufficient  for the payment  thereof set apart for payment
for all past dividend periods and the then current dividend period,  and (ii) if
such  series of  Preferred  Shares  does not have a  cumulative  dividend,  full
dividends on the Preferred  Shares of any series have been or  contemporaneously
are declared and paid or declared and a sum sufficient  for the payment  thereof
set apart for payment for the then current  dividend  period,  the Company shall
not purchase or otherwise acquire directly or indirectly any Preferred Shares of
such series  (except by  conversion  into or exchange  for capital  stock of the
Company  ranking  junior to the Preferred  Shares of such series as to dividends
and upon liquidation).

     If fewer than all of the outstanding  Preferred Shares of any series are to
be redeemed, the number of Preferred Shares to be redeemed will be determined by
the Company and such shares may be redeemed  pro rata from the holders of record
of such shares in  proportion  to the number of such shares held by such holders
(with adjustments to avoid redemption of fractional  shares) or by lot in manner
determined by the Company.

   
     Notice of  redemption  will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of record of Preferred  Shares of
any series to be redeemed at the address  shown on the stock  transfer  books of
the Company.  Each notice shall state:  (i) the redemption date; (ii) the number
of  shares  and  series  of the  Preferred  Shares  to be  redeemed;  (iii)  the
redemption price; (iv) the place or places where certificates for such Preferred
Shares are to be  surrendered  for  payment of the  redemption  price;  (v) that
dividends on the shares to be redeemed  will cease to accrue on such  redemption
date; and (vi) the date upon which the holder's conversion rights, if any, as to
such  shares  shall  terminate.  If fewer than all the  Preferred  Shares of any
series are to be redeemed,  the notice mailed to each such holder  thereof shall
also  specify  the  number of  Preferred  Shares to be  redeemed  from each such
holder.  If notice of redemption  of any Preferred  Shares has been given and if
the funds  necessary for such  redemption  have been set aside by the Company in
trust for the  benefit of the holders of any of the  Preferred  Shares so called
for redemption,  then from and after the redemption date dividends will cease to
accrue on such Preferred  Shares,  and any and all rights of the holders of such
shares will terminate, except the right to receive the redemption price.
    

Liquidation Preference

     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Company,  then,  before any  distribution or payment shall be
made to the holders of any Common Shares or any other class or series of capital
stock of the Company ranking junior to the Preferred  Shares in the distribution
of assets upon any  liquidation,  dissolution or winding up of the Company,  the
holders of each series of  Preferred  Shares shall be entitled to receive out of
assets  of the  Company  legally  available  for  distribution  to  shareholders
liquidating  distributions in the amount of the liquidation preference per share
(set forth in the applicable Prospectus Supplement), plus an amount equal to all
dividends  accrued and unpaid thereon (which shall not include any  accumulation
in respect of unpaid  dividends  for prior  dividend  periods if such  Preferred


                                       16

<PAGE>


Shares do not have a cumulative  dividend).  After payment of the full amount of
the  liquidating  distributions  to which  they are  entitled,  the  holders  of
Preferred  Shares will have no right or claim to any of the remaining  assets of
the  Company.  In  the  event  that  upon  any  such  voluntary  or  involuntary
liquidation,  dissolution or winding up, the available assets of the Company are
insufficient  to  pay  the  amount  of  the  liquidating  distributions  on  all
outstanding Preferred Shares and the corresponding amounts payable on all shares
of other classes or series of capital  stock of the Company  ranking on a parity
with the Preferred Shares in the distribution of assets, then the holders of the
Preferred  Shares and all other such  classes or series of capital  stock  shall
share  ratably  in any such  distribution  of assets in  proportion  to the full
liquidating   distributions  to  which  they  would  otherwise  be  respectively
entitled.

     If liquidating distributions shall have been made in full to all holders of
Preferred Shares, the remaining assets of the Company shall be distributed among
the holders of any other classes or series of capital  stock  ranking  junior to
the Preferred Shares upon  liquidation,  dissolution or winding up, according to
their  respective  rights and  preferences  and in each case  according to their
respective number of shares.  For such purposes,  the consolidation or merger of
the Company with or into any other trust or corporation,  or the sale,  lease or
conveyance  of all or  substantially  all of the  property  or  business  of the
Company, shall not be deemed to constitute a liquidation, dissolution or winding
up of the Company.

Voting Rights

     Holders of the Preferred Shares will not have any voting rights,  except as
set  forth  below  or as  otherwise  from  time  to time  required  by law or as
indicated in the applicable Prospectus Supplement.

     Unless otherwise specified in the related Prospectus Statement, at any time
dividends  on any  Preferred  Shares  shall be in  arrears  for six  consecutive
quarterly periods,  the holders of such Preferred Shares (voting separately as a
class with all other  series of preferred  shares upon which like voting  rights
have  been  conferred  and are  exercisable)  will be  entitled  to vote for the
election of two additional trustees of the Company at the next annual meeting of
shareholders  and at  each  subsequent  meeting  until  (i) if  such  series  of
Preferred Shares has a cumulative  dividend,  all dividends  accumulated on such
Preferred  Shares for the past  dividend  periods and the then current  dividend
period  shall have been  fully paid or  declared  and a sum  sufficient  for the
payment thereof set aside for payment or (ii) if such series of Preferred Shares
does not have a cumulative dividend,  four consecutive quarterly dividends shall
have been fully paid or declared and a sum  sufficient  for the payment  thereof
set aside for payment. In such case, the entire Board of Trustees of the Company
will be increased by two trustees.

   
     Unless provided  otherwise for any series of Preferred  Shares,  so long as
any Preferred  Shares  remain  outstanding,  the Company shall not,  without the
affirmative  vote or consent of the  holders of a majority of the shares of each
series of Preferred Shares outstanding at the time, given in person or by proxy,
either in writing or at a meeting  (such series  voting  separately as a class),
(i)  authorize or create,  or increase the  authorized  or issued amount of, any
class or series of  capital  stock  ranking  prior to such  series of  Preferred
Shares with respect to payment of dividends or the  distribution  of assets upon
liquidation,  dissolution or winding up, or reclassify  any  authorized  capital
stock of the Company  into any such  shares,  or create,  authorize or issue any
obligation or security  convertible into or evidencing the right to purchase any
such shares; or (ii) amend, alter or repeal the provisions of the Declaration or
the certificate of designations for such series of Preferred Shares,  whether by
merger, consolidation or otherwise, so as to materially and adversely affect any
right, preference,  privilege or voting power of such series of Preferred Shares
or the holders thereof;  provided,  however,  that any increase in the amount of
the authorized  Preferred Shares or the creation or issuance of any other series
of Preferred  Shares, or any increase in the amount of authorized shares of such
series or any other series of Preferred Shares, in each case ranking on a parity
with or junior to the Preferred Shares of such series with respect to payment of
dividends or the distribution of assets upon liquidation, dissolution or winding
up,  shall  not be  deemed to  materially  and  adversely  affect  such  rights,
preferences, privileges or voting powers.
    

     The foregoing voting  provisions will not apply if, at or prior to the time
when the act with respect to which such vote would  otherwise be required  shall
be effected, all outstanding shares of such series of Preferred Shares

                                       17

<PAGE>



shall have been redeemed or called for  redemption  and  sufficient  funds shall
have been deposited in trust to effect such redemption.

     As more fully described under  "Description of Depositary Shares" below, if
the Company elects to issue Depositary  Shares,  each representing a fraction of
share of a series of the Preferred Shares,  each such Depositary will, in effect
be entitled to such fraction of a vote per Depositary Share.

Conversion Rights

   
     The  terms and  conditions,  if any,  upon  which  shares of any  series of
Preferred Shares may be converted into or exchanged for Common Shares or another
series of  Preferred  Shares or other series of Offered  Securities  will be set
forth in the Prospectus Supplement relating thereto. Such terms will include the
number of Common Shares or other  securities  into which the Preferred  Share is
convertible  or  exchangeable,  conversion  or  exchange  price  (or  manner  of
calculation  thereof),  the  conversion  or exchange  period,  provisions  as to
whether  conversion  or  exchange  will be at the  option of the  holders of the
Preferred  Shares or the  Company,  the events  requiring an  adjustment  of the
conversion or exchange price and provisions  affecting conversion or exchange in
the event of the redemption such Preferred Shares.
    

                        DESCRIPTION OF DEPOSITARY SHARES

General

     The description set forth below and in any applicable Prospectus Supplement
of certain  provisions of any Deposit  Agreement  (as defined  below) and of the
Depositary Shares and Depositary Receipts does not purport to be complete and is
subject to and  qualified  in its  entirety by reference to the forms of Deposit
Agreement  and  Depositary  Receipts  relating to each  series of the  Preferred
Shares which have been or will be filed with the  Commission  at or prior to the
time of the offering of such series of the Preferred Shares.

   
     The Company  may, at its option,  elect to offer  fractional  interests  in
shares of Preferred Shares, rather than shares of Preferred Shares. In the event
such  option is  exercised,  the  Company  will  provide  for the  issuance by a
Depositary (as defined  below) to the public of receipts for Depositary  Shares,
each of which  will  represent  a  fractional  interest  to be set  forth in the
Prospectus  Supplement  relating to a particular  series of the Preferred Shares
which will be filed with the  Commission at or prior to the time of the offering
of such series of the Preferred Shares as described  below.  Preferred Shares of
each series  represented by Depositary Shares will be deposited under a separate
deposit  agreement  (each,  a "Deposit  Agreement")  among the  Company  and the
depositary named therein (a "Depositary"). The Prospectus Supplement relating to
a series  of  Depositary  Shares  will set  forth  the name and  address  of the
Depositary. Subject to the terms of the applicable Deposit Agreement, each owner
of a Depositary Share will be entitled, in proportion to the fractional interest
of a share of a  particular  series  of  Preferred  Shares  represented  by such
Depositary  Share to all the  rights and  preferences  of the  Preferred  Shares
represented by such Depositary Shares (including dividend,  voting,  conversion,
redemption and liquidation rights).
    

     The  Depositary  Shares will be evidenced  by  Depositary  Receipts  issued
pursuant to the  applicable  Deposit  Agreement.  Upon  surrender of  Depositary
Receipts  at the  office  of the  Depositary  and upon  payment  of the  charges
provided in the Deposit Agreement and subject to the terms thereof,  a holder of
Depositary Shares is entitled to have the Depositary  deliver to such holder the
whole shares of Preferred Shares  underlying the Depositary  Shares evidenced by
the surrendered Depositary Receipts.


                                       18

<PAGE>



Dividends and Other Distributions

     A Depositary  will be required to  distribute  all cash  dividends or other
cash distributions received in respect of the applicable Preferred Shares to the
record holders of Depositary  Receipts  evidencing the related Depositary Shares
in proportion to the number of such  Depositary  Receipts owned by such holders,
subject to certain obligations of holders to file proofs, certificates and other
information  and to  pay  certain  charges  and  expenses  to  such  Depositary.
Fractions will be rounded down to the market whole cent.

     In the event of a  distribution  other than in cash, a  Depositary  will be
required  to  distribute  property  received  by it to  the  record  holders  of
Depositary Receipts entitled thereto,  subject to certain obligations of holders
to file proofs,  certificates  and other  information and to pay certain charges
and expenses to such  Depositary,  unless such Depositary  determines that it is
not feasible to make such distribution,  in which case such Depositary may, with
the approval of the Company,  sell such property and distribute the net proceeds
from such sale to such holders.

     No  distributions  will be made in respect of any  Depositary  Share to the
extent that it  represents  any  Preferred  Shares which have been  converted or
exchanged.  The Deposit Agreement will also contain  provisions  relating to the
manner in which any  subscription  or similar  rights  offered by the Company to
holders of the Preferred Shares shall be made available to holders of Depositary
Shares.

Redemption of Depositary Shares

   
     If a series of the Preferred  Shares  underlying the  Depositary  Shares is
subject to redemption,  the Depositary Shares will be redeemed from the proceeds
received by the Depositary  resulting from the redemption,  in whole or in part,
of such series of the Preferred  Shares held by the  Depositary.  The Depositary
shall mail notice of redemption not less than 30 and not more than 60 days prior
to the date  fixed  for  redemption  to the  record  holders  of the  Depositary
Receipts  evidencing the Depositary Shares to be so redeemed at their respective
addresses  appearing  in  the  Depositary's  books.  The  redemption  price  per
Depositary  Share will be equal to the  applicable  fraction  of the  redemption
price per share  payable  with respect to such series of the  Preferred  Shares.
Whenever the Company redeems shares of Preferred  Shares held by the Depositary,
the  Depositary  will  redeem  as of the  same  redemption  date the  number  of
Depositary  Shares relating to shares of Preferred  Shares so redeemed.  If less
than all of the Depositary  Shares are to be redeemed,  the Depositary Shares to
be  redeemed  will be selected  by lot or pro rata as may be  determined  by the
Depositary.
    

     After the date fixed for  redemption,  the Depositary  Shares so called for
redemption  will no longer be deemed  to be  outstanding  and all  rights of the
holders of the Depositary Shares and the related Depositary Receipts will cease,
except the right to receive  the moneys  payable  upon such  redemption  and any
money or other  property  to which the  holders of such  Depositary  Shares were
entitled upon such redemption upon surrender to the Depositary of the Depositary
Receipts evidencing such Depositary Shares.

Voting of the Preferred Shares

     Upon  receipt  of  notice  of any  meeting  at  which  the  holders  of the
applicable  Preferred Shares are entitled to vote, a Depositary will be required
to mail the  information  contained  in such  notice of  meeting  to the  record
holders of the  Depositary  Receipts  evidencing  the  Depositary  Shares  which
represent  such  Preferred  Shares.  Each record holder of  Depositary  Receipts
evidencing  Depositary Shares on the record date (which will be the same date as
the record date for the  Preferred  Shares)  will be  entitled to instruct  such
Depositary as to the exercise of the voting  rights  pertaining to the amount of
Preferred Shares represented by such holder's Depositary Shares. Such Depositary
will  endeavor,  insofar as  practical,  to vote the amount of Preferred  Shares
represented by such Depositary Shares in accordance with such instructions,  and
the  Company  will  agree to take all  reasonable  action  which  may be  deemed
necessary by such  Depositary in order to enable such  Depositary to do so. Such
Depositary  will be  required  to abstain  from  voting the amount of  Preferred
Shares  represented by such Depositary  Shares to the extent it does not receive
specific instructions from the holders of Depositary Receipts evidencing such

                                       19

<PAGE>



Depositary  Shares.  The Depositary  will not be responsible  for any failure to
carry out any  instruction to vote, or for the manner or effect of any such vote
made,  as long as such action or non-action is in good faith and does not result
from gross negligence or willful misconduct of such Depositary.

Liquidation Preference

     In the event of the liquidation,  dissolution or winding up of the Company,
whether  voluntary or involuntary,  the holders of each Depositary Share will be
entitled to the fraction of the liquidation  preference  accorded each Preferred
Share  represented  by such  Depositary  Share,  as set forth in the  applicable
Prospectus Supplement.

Conversion of Preferred Shares

     The  Depositary   Shares,   as  such,  will  not  be  convertible  into  or
exchangeable  for Common  Shares,  Preferred  Shares or any other  securities or
property  of the  Company.  Nevertheless,  if so  specified  in  the  applicable
Prospectus  Supplement  relating  to  an  offering  of  Depositary  Shares,  the
Depositary  Receipts may be  surrendered  by holders  thereof to the  applicable
Depositary with written  instructions to such Depositary to instruct the company
to cause  conversion  or exchange of the  Preferred  Shares  represented  by the
Depositary Share evidenced by such Depositary Receipts into Common Shares, other
shares of Preferred  Shares of the Company or such other  securities as shall be
provided  therein,  and  the  Company  will  agree  that  upon  receipt  of such
instruction  and any  amounts  payable  in  respect  thereof,  it will cause the
conversion or exchange  thereof  utilizing the same procedures as those provided
for delivery of Preferred  Shares to effect such conversion or exchange.  If the
Depositary Shares evidenced by a Depositary  Receipt are to be converted in part
only, a new  Depositary  Receipt or  Depositary  Receipts will be issued for any
Depositary Shares not to be converted.

Amendment and Termination of a Deposit Agreement

     Any  form  of  Depositary  Receipt  evidencing  Depositary  Shares  and any
provision of a Deposit  Agreement will be permitted at any time to be amended by
agreement  between the  Company  and the  applicable  Depositary.  However,  any
amendment  that  materially  and  adversely  alters the rights of the holders of
Depositary  Shares will not be effective unless such amendment has been approved
by the  existing  holders of at least a majority  of the  applicable  Depositary
Shares then outstanding.  Every holder of an outstanding  Depositary  Receipt at
the time any such amendment  becomes effective shall be deemed, by continuing to
hold such Depositary  Receipt,  to consent and agree to such amendment and to be
bound by the applicable Deposit Agreement as amended thereby.

   
     Any Deposit  Agreement  may be terminated by the Company upon not less than
30  days'  prior  written  notice  to the  applicable  Depositary  if  (i)  such
termination  is necessary to preserve the  Company's  status as a REIT or (ii) a
majority  of each  series  of  Preferred  Shares  affected  by such  termination
consents to such  termination,  whereupon  such  Depositary  will be required to
deliver or make available to each holder of Depositary Receipts,  upon surrender
of the  Depositary  Receipts  held by such  holder,  such  number  of  whole  or
fractional  Preferred  Shares  as  are  represented  by  the  Depositary  Shares
evidenced by such Depositary  Receipts  together with any other property held by
such  Depositary  with receipts to such  Depositary  Receipts.  The Company will
agree in each Depositary  Agreement that if such Deposit Agreement is terminated
to preserve the Company's  status as a REIT,  then the Company will use its best
efforts to list the  Preferred  Shares  issued  upon  surrender  of the  related
Depositary  Shares on a national  securities  exchange.  In addition,  a Deposit
Agreement will automatically  terminate if (i) all outstanding Depositary Shares
thereunder  shall  have  been  redeemed;  (ii)  there  shall  have  been a final
distribution in respect of the related  Preferred  Shares in connection with any
liquidation,  dissolution  or winding up of the  Company  and such  distribution
shall have been distributed to the holders of Depositary Receipts evidencing the
Depositary Shares underlying such Preferred Shares; or (iii) each of the related
Preferred  Shares shall have been converted or exchanged into  securities not so
represented by Depositary Shares.
    


                                       20

Charges of a Depositary

     The Company will pay all transfer and other taxes and governmental  charges
arising  solely from the  existence of a Deposit  Agreement.  In  addition,  the
Company will pay the fees and expenses of a Depositary  in  connection  with the
initial deposit of the Preferred Shares and any redemption of Preferred  Shares.
However,  holders  of  Depositary  Receipts  will  pay  any  transfer  or  other
governmental  charges and the fees and expenses of a  Depositary  for any duties
requested by such holders to be performed  which are outside of those  expressly
provided for in the applicable Deposit Agreement.

Resignation and Removal of Depositary

   
     A Depositary  may resign at any time by delivering to the Company notice of
its election to do so, and the Company may at any time remove a Depositary,  any
such  resignation or removal to take effect upon the  appointment of a successor
Depositary.  A successor  Depositary will be required to be appointed  within 60
days after delivery of the notice of resignation or removal and will be required
to be a bank or trust company  having its principal  office in the United States
and having a combined capital and surplus of at least $50 million.
    

Miscellaneous

     A Depositary will be required to forward to holders of Depositary  Receipts
any  reports and  communications  from the  Company  which are  received by such
Depositary with respect to the related Preferred Shares.

   
     Neither  Depositary  nor the Company will be liable if it is prevented from
or delayed in, by law or any  circumstances  beyond its control,  performing its
obligations  under a Deposit  Agreement.  The  obligations  of the Company and a
Depositary under a Deposit  Agreement will be limited to performing their duties
thereunder in good faith and without gross negligence or willful misconduct, and
neither the Company nor any applicable Depositary will be obligated to prosecute
or defend any legal proceeding in respect of any Depositary Receipts, Depositary
Shares or Preferred Shares represented thereby unless satisfactory  indemnity is
furnished.  The Company and any Depositary  will be permitted to rely on written
advice of counsel or accountants,  or information provided by persons presenting
Preferred Shares represented thereby for deposit, holders of Depositary Receipts
or  other  persons  believed  in  good  faith  to  be  competent  to  give  such
information, and on documents believed in good faith to be genuine and signed by
a proper party.
    

     In the event a Depositary  shall receive  conflicting  claims,  requests or
instructions from any holders of Depositary  Receipts,  on the one hand, and the
Company,  on the other hand,  such  Depositary  shall be entitled to act on such
claims, requests or instructions received from the Company.

                             DESCRIPTION OF WARRANTS

   
     The Company may issue, together with any other series of Offered Securities
or  separately,  Warrants  entitling  the holder to purchase from or sell to the
Company,  or to receive from the Company the cash value of the right to purchase
or sell, Debt Securities,  Preferred Shares, Depositary Shares or Common Shares.
The  Warrants  are to be  issued  under  Warrant  Agreements  (each  a  "Warrant
Agreement")  to be entered  into  between the  Company and a warrant  agent (the
"Warrant  Agent"),  all as set  forth in the  applicable  Prospectus  Supplement
relating to the particular issue of Warrants.
    

     In  the  case  of  each  series  of  Warrants,  the  applicable  Prospectus
Supplement  will  describe  the terms of the  Warrants  being  offered  thereby,
including  the  following,  if  applicable:  (i) the  offering  price;  (ii) the
currencies  in which  such  Warrants  are being  offered;  (iii)  the  number of
Warrants offered; (iv) the securities underlying the Warrants;  (v) the exercise
price,  the  procedures for exercise of the Warrants and the  circumstances,  if
any,  that will cause the Warrants to be deemed to be  automatically  exercised;
(vi) the date on which the right shall  expire;  (vii) U.S.  federal  income tax
consequences; and (viii) other terms of the Warrants.

                                       21

<PAGE>



     Warrants may be exercised at the appropriate office of the Warrant Agent or
any other office indicated in the applicable Prospectus Supplement. Prior to the
exercise of Warrants entitling the holder to purchase any securities, holders of
such  Warrants  will not have any of the  rights of  holders  of the  securities
purchasable  upon such  exercise  and will not be entitled  to payments  made to
holders of such securities.

     The Warrant  Agreements may be amended or supplemented  without the consent
of the holders of the Warrants issued  thereunder to effect changes that are not
inconsistent  with the  provisions  of the  Warrants  and that do not  adversely
affect the interests of the holders of the Warrants.

                 LIMITATION OF LIABILITY; SHAREHOLDER LIABILITY

   
     Maryland law permits a REIT to provide, and the Declaration provides,  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, and that, as far as practicable,  each written agreement of
the Company is to contain a  provision  to that  effect.  Despite  these  facts,
counsel  has  advised the Company  that in some  jurisdictions  the  possibility
exists that  shareholders of a  non-corporate  entity such as the Company may be
held  liable for acts or  obligations  of the  Company.  Counsel has advised the
Company  that the  State  of Texas  may not give  effect  to the  limitation  of
shareholder  liability afforded by Maryland law, but that Texas law would likely
recognize  contractual  limitations of liability such as those discussed  above.
The  Company  intends to conduct its  business in a manner  designed to minimize
potential  shareholder  liability by, among other things,  inserting appropriate
provisions in written  agreements of the Company;  however,  no assurance can be
given  that   shareholders   can  avoid   liability  in  all  instances  in  all
jurisdictions.
    

     The  Declaration  provides that,  upon payment by a shareholder of any such
liability,  the shareholder will be entitled to  indemnification by the Company.
There can be no assurance  that, at the time any such  liability  arises,  there
will  be  assets  of  the   Company   sufficient   to  satisfy   the   Company's
indemnification obligation. The Trustees intend to conduct the operations of the
Company,  with the advice of counsel,  in such a way as to minimize or avoid, as
far as practicable,  the ultimate  liability of the shareholders of the Company.
The  Trustees  do not intend to  provide  insurance  covering  such risks to the
shareholders.

        REDEMPTION; BUSINESS COMBINATIONS AND CONTROL SHARE ACQUISITIONS

Redemption and Business Combinations

     For the Company to qualify as a REIT under the Code,  in any taxable  year,
not more than 50% in value of its outstanding  Shares may be owned,  directly or
indirectly by five or fewer individuals during the last six months of such year,
and the shares must be owned by 100 or more persons  during at least 335 days of
a taxable year or a proportionate part of a taxable year less than 12 months. In
order to meet  these  and other  requirements,  the  Trustees  have the power to
redeem or prohibit the transfer of a sufficient  number of Shares to maintain or
bring the ownership of the Shares into  conformity  with such  requirements.  In
connection  with the foregoing,  if the Trustees  shall, at any time and in good
faith,  be  of  the  opinion  that  direct  or  indirect   ownership  of  shares
representing  more  than  8.5% in value of the  total  Shares  outstanding  (the
"Excess  Shares") has or may become  concentrated in the hands of one beneficial
owner,  other than Excepted  Persons,  the Trustees  shall have the power (i) to
purchase from any  shareholder  of the Company such Excess  Shares,  and (ii) to
refuse to  transfer  or issue  Shares to any person  whose  acquisition  of such
Shares would,  in the opinion of the Trustees,  result in the direct or indirect
beneficial  ownership  by any  person of Shares  representing  more than 8.5% in
value of the  outstanding  Shares.  Any  transfer of Shares,  options,  or other
securities  convertible  into Shares that would create a beneficial owner (other
than any of the Excepted Persons) of Shares representing more than 8.5% in value
of the total Shares outstanding shall be deemed void ab initio, and the intended
transferee  shall be deemed never to have had an interest  therein.  Further the
Declaration  provides  that  transfers  or  purported  acquisitions,   directly,
indirectly or by attribution,  of Shares, or securities convertible into Shares,
that could result in disqualification of the Company as a REIT are null and void
and permits the Trustees to repurchase  Shares or other securities to the extent


                                       22

<PAGE>


necessary to maintain the Company's status as a REIT. The purchase price for any
Shares  so  purchased  shall be  determined  by the  price of the  Shares on the
principal  exchange  on  which  they  are then  traded,  or if no such  price is
available, then the purchase price shall be equal to the net asset value of such
Shares as determined by the Trustees in accordance with applicable law. From and
after the date fixed for purchase by the Trustees, and so long as payment of the
purchase  price for the  Shares to be so  redeemed  shall have been made or duly
provided for, the holder of any Excess Shares so called for purchase shall cease
to be entitled to  distributions,  voting rights and any and all other  benefits
with respect to such Shares,  except the right to payment of the purchase  price
for the Shares.

     The  Declaration  also  requires  that  Business  Combinations  between the
Company  and a  beneficial  holder of 10% or more of the  outstanding  Shares (a
"Related Person") be approved by the affirmative vote of the holders of at least
75% of the Shares unless (1) the Trustees by unanimous  vote or written  consent
shall have  expressly  approved in advance the  acquisition  of the  outstanding
Shares that caused the Related  Person to become a Related  Person or shall have
approved the Business  Combination  prior to the Related Person  involved in the
Business  Combination  having  become  a  Related  Person;  or (2) the  Business
Combination  is solely  between the Company  and a 100% owned  affiliate  of the
Company.  As  permitted  by law,  the Company has elected to be governed by such
provisions  rather  than  the  provisions  of  Subtitle  6 of  Title  3  of  the
Corporations  and  Associations  Article  of  the  Annotated  Code  of  Maryland
regarding business combinations.

     Under the Declaration the number of trustees may be fixed from time to time
by  two-thirds  of the  Trustees or by an amendment  of the  Declaration  by the
shareholders  of the  Company,  with a  minimum  of three  and a  maximum  of 12
trustees, a majority of whom must be Independent Trustees. The Declaration fixes
the current  number of trustees of the Company at five and divides the  Trustees
into three groups.  Trustees in each group are elected to three-year  terms.  As
the  trustees'  terms  expire,  replacements  are  elected by a majority  of the
outstanding  Shares.  The  classified  nature of the  Trustees  may make it more
difficult for the  shareholders  to remove the management of the Company than if
all  trustees  were  elected on an annual  basis.  Vacancies  may be filled by a
majority of the remaining trustees,  except that a vacancy among the Independent
Trustees must be filled by a majority of the remaining  Independent  Trustees or
by majority vote of the Company's  shareholders.  Any trustee may be removed for
cause by all the remaining  trustees,  or without cause by vote of two-thirds of
the Shares then outstanding and entitled to vote thereon.

     The provisions regarding business combinations and the classified nature of
the Trustees and certain  other  matters may not be repealed or amended  without
the affirmative  vote of at least 75% of the of the shareholders of the Company,
provided that the Trustees,  by two-thirds  vote,  may,  without the approval or
consent  of the  shareholders,  adopt  any  amendment  that  they in good  faith
determine  to be  necessary to permit the Company to qualify as a REIT under the
Code.

     The foregoing  provisions  may have the effect of  discouraging  unilateral
tender offers or other takeover proposals which certain  shareholders might deem
in their interests or pursuant to which they might receive a substantial premium
for their  Shares.  The  provisions  could  also have the  effect of  insulating
current  management  against the  possibility of removal and could,  by possibly
reducing  temporary  fluctuations  in market  price caused by  accumulations  of
Shares,  deprive  shareholders of opportunities to sell at a temporarily  higher
market  price.  However,  the Trustees  believe  that  inclusion of the business
combination  provisions  in the  Declaration  may help assure fair  treatment of
shareholders and preserve the assets of the Company.

Control Share Acquisition

   
     Maryland law provides for a limitation of voting rights in a "control share
acquisition".  The Maryland  statute defines a control share  acquisition at the
20%,  33 1/3%  and 50%  acquisition  levels,  and  requires  a  two-thirds  vote
(excluding  shares  owned  by  the  acquiring  person  and  certain  members  of
management)  to  accord  voting  rights to shares  acquired  in a control  share
acquisition.  The statute  would  require  the target  company to hold a special
meeting at the request of an actual or proposed  control share acquiror  subject
to compliance with certain conditions by such acquiror. In addition,  unless the
charter, declaration of trust or By-Laws provide otherwise, the statute

                                       23

<PAGE>



gives the company, within certain time limitations, various redemption rights if
there is a  shareholder  vote on the issue and the grant of voting rights is not
approved,  or if an "acquiring  person statement" is not delivered to the target
company within 10 days following a control share acquisition.  Moreover,  unless
the charter,  declaration  of trust or By-Laws  provide  otherwise,  the statute
provides that if, before a control share acquisition  occurs,  voting rights for
control shares are approved at a shareholders'  meeting and the acquiror becomes
entitled  to vote a majority  of the  shares  entitled  to vote,  then all other
shareholders may exercise appraisal rights. The statute does not apply to shares
acquired in a merger,  consolidation or share exchange if the company is a party
to the  transaction.  An  acquisition of shares may be exempted from the control
share statute provided that a charter,  declaration of trust or By-Law provision
is adopted for such purpose prior to the control share acquisition. There are no
such provisions in the Declaration or By-Laws of the Company.
    

Rights Plan

     In October  1994 the Board of Trustees  adopted a  shareholder  rights plan
(the  "Rights  Plan")  under  which one  Junior  Participating  Preferred  Share
purchase  right  (a  "Right")  was   distributed  for  each  Common  Share  then
outstanding.  Each  Right  entitles  the  holder  to  buy  1/100th  of a  Junior
Participating  Preferred Share (or, in certain  circumstances,  to receive cash,
property, Common Shares or other securities of the Company) at an exercise price
of $50 per 1/100th of a Junior Participating Preferred Share.

     Initially,  the Rights  are  attached  to  certificates  representing  then
outstanding  Common Shares. The Rights will separate from such Common Shares and
a  "Distribution  Date" will occur upon the earlier of (1) 10 business  days (or
such  later date as the  Company's  Board of  Trustees  may  determine  before a
Distribution Date occurs) following a public  announcement by the Company that a
person or group of affiliated or associated persons, with certain exceptions (an
"Acquiring  Person"),  has  acquired,  or has  obtained  the  right to  acquire,
beneficial  ownership of 10% or more of the outstanding  Common Shares (the date
of such announcement  being a "Share Acquisition Date") or (ii) 10 business days
(or such later date as the Company's  Board of Trustees may  determine  before a
Distribution  Date  occurs)  following  the  commencement  of a tender  offer or
exchange offer that would result in a person becoming an Acquiring Person.

     Until the  Distribution  Date,  (i) the  Rights  will be  evidenced  by the
certificates  for Common Shares and will be transferred  with and only with such
Common  Share  certificates,  (ii)  Common  Share  certificates  will  contain a
notation  incorporating  the rights agreement  pursuant to which the Rights were
issued  (the  "Rights  Agreement")  by  reference  and (iii) the  surrender  for
transfer of any certificates for Common Shares  outstanding will also constitute
the transfer of the Rights associated with the Common Shares represented by such
certificates.

     The Rights are not exercisable  until the Distribution Date and will expire
at the close of  business  on October  17,  2004,  unless  earlier  redeemed  or
exchanged by the Company as described  below.  Until a Right is  exercised,  the
holder  thereof,  as  such,  has no  rights  as a  shareholder  of the  Company,
including, without limitation, the right to vote or to receive dividends.

     In the event (a  "Flip-In  Event") a Person  becomes  an  Acquiring  Person
(except pursuant to a tender or exchange offer for all outstanding Common Shares
at a price and on terms which a majority of the Company's  Outside  Trustees (as
defined in the Rights  Agreement)  determines to be fair to and otherwise in the
best  interests  of the Company and its  shareholders  (a "fair  offer")),  each
holder of a Right will  thereafter  have the right to receive,  upon exercise of
such Right, Common Shares (or, in certain circumstances, cash, property or other
securities  of the  Company)  having a Current  Market  Price (as defined in the
Rights  Agreement)  equal  to  two  times  the  exercise  price  of  the  Right.
Notwithstanding  the  foregoing,  following the occurrence of any Flip-In Event,
all Rights that are, or (under  certain  circumstances  specified  in the Rights
Agreement)  were,  beneficially  owned by any  Acquiring  Person  (or by certain
related  parties)  will be null and void in the  circumstances  set forth in the
Rights  Agreement.  However,  Rights  will  not  be  exercisable  following  the
occurrence  of any  Flip-In  Event  until  such time as the Rights are no longer
redeemable by the Company as set forth below.


                                       24

<PAGE>



     In the event (a "Flip-Over  Event") that, at any time on or after the Share
Acquisition  Date, (i) the Company shall take part in a merger or other business
combination  transaction  (other than certain  mergers that follow a fair offer)
and the Company shall not be the surviving entity or (ii) the Company shall take
part in a merger or other business  combination  transaction in which the Common
Shares are changed or exchanged  (other than certain  mergers that follow a fair
offer) or (iii) 50% or more of the Company's  assets or earning power is sold or
transferred,  each holder of a Right (except Rights which  previously  have been
voided,  as set forth above) shall  thereafter  have the right to receive,  upon
exercise,  a number of shares of common stock of the acquiring  company having a
Current Market Price equal to two times the exercise price of the Right. Flip-In
Events and Flip-Over Events are collectively referred to as "Triggering Events."

     The Purchase Price payable and the number of Junior Participating Preferred
Shares (or the  amount of cash,  property  or other  securities)  issuable  upon
exercise  of the Rights are subject to  adjustment  from time to time to prevent
dilution (i) in the event of a share dividend on, or a subdivision,  combination
or  reclassification  of, the Junior  Participating  Preferred  Shares,  (ii) if
holders of the Junior Participating  Preferred Shares are granted certain rights
or  warrants  to  subscribe  for  Junior   Participating   Preferred  Shares  or
convertible  securities  at less than the  Current  Market  Price of the  Junior
Participating  Preferred Shares or (iii) upon the distribution to holders of the
Junior  Participating  Preferred  Shares of evidences of  indebtedness or assets
(excluding  regular  quarterly  cash  dividends)  or of  subscription  rights or
warrants  (other than those  referred to above).  With  certain  exceptions,  no
adjustment in the Purchase Price will be required until  cumulative  adjustments
amount to at least 1% of the  Purchase  Price.  The  Company is not  required to
issue fractional  Shares upon the exercise of any Right, and in lieu thereof,  a
cash payment will be made.

     At any time until 10 business days  following the Share  Acquisition  Date,
the Company may redeem the Rights in whole,  but not in part, at a price of $.01
per Right,  payable,  at the option of the Company,  in cash,  Common  Shares or
other consideration as the Board of Trustees may determine. Immediately upon the
effectiveness  of the  action  of  the  Company's  Board  of  Trustees  ordering
redemption  of the Rights,  the Rights will  terminate and the only right of the
holders of Rights will be to receive the $.01 per Right redemption price.

     The term of the  Rights,  other  than key  financial  terms and the date on
which the Rights expire,  may be amended by the Board of Trustees of the Company
prior  to the  Distribution  Date.  Thereafter,  the  provisions  of the  Rights
Agreement  may be  amended  by the Board of  Trustees  only in order to cure any
ambiguity,  defect or  inconsistency,  to make  changes  which do not  adversely
affect the  interests  of  holders of Rights  (excluding  the  interests  of any
Acquiring  Person and certain other  related  parties) or to shorten or lengthen
any time period under the Rights Agreement; provided, however, that no amendment
to lengthen the time period governing redemption is permitted to be made at such
time as the Rights are not redeemable.

                              PLAN OF DISTRIBUTION

     The Company may sell the Offered Securities to one or more underwriters for
public offering and sale by them or may sell the Offered Securities to investors
directly or through agents.  Any such underwriter or agent involved in the offer
and sale of the Offered  Securities  will be named in the applicable  Prospectus
Supplement.

   
     The distribution of Offered Securities may be effected from time to time in
one or more  transactions at a fixed price or prices,  which may be changed,  at
market prices  prevailing at the time of sale, at prices  related to such market
prices  or at  negotiated  prices.  In  connection  with  the  sale  of  Offered
Securities,  underwriters  or agents may  receive or be deemed to have  received
compensation  from the Company or from  purchasers  in the form of  underwriting
discounts, concessions or commissions.  Underwriters may sell Offered Securities
to or through dealers,  and such dealers may receive compensation in the form of
discounts, concessions or commissions from the underwriters or from purchasers.

     Any underwriting compensation paid by the Company to underwriters or agents
in  connection  with the  offering  of Offered  Securities,  and any  discounts,
concessions or commissions  allowed by  underwriters to  participating  dealers,


                                       25

<PAGE>



will be set forth in the applicable Prospectus Supplement. Underwriters, dealers
and agents  participating in the  distribution of the Offered  Securities may be
deemed  to be  underwriters,  and any  discounts,  concessions  and  commissions
received  by them and any  profit  realized  by them on  resale  of the  Offered
Securities may be deemed to be underwriting discounts and commissions, under the
Securities  Act.  Underwriters,  dealers  and  agents  may  be  entitled,  under
agreements  entered  into  with the  Company,  to  indemnification  against  and
contribution toward certain civil liabilities,  including  liabilities under the
Securities Act.

     If so indicated in the applicable Prospectus  Supplement,  the Company will
authorize  underwriters  or other  persons  acting  as the  Company's  agents to
solicit offers by certain  institutions to purchase Offered  Securities from the
Company at the public  offering  price set forth in such  Prospectus  Supplement
pursuant to  contracts  providing  for payment and  delivery on a future date or
dates.  Institutions  with whom such  contracts,  when  authorized,  may be made
include  commercial  and savings  banks,  insurance  companies,  pension  funds,
investment  companies,   educational  and  charitable  institutions,  and  other
institutions,  but will in all cases be subject to the  approval of the Company.
Any such  contracts  will be subject to the  condition  that the  purchase by an
institution of the Offered  Securities covered by its contracts shall not at the
time of delivery be prohibited  under the law of any  jurisdiction in the United
States to which such  institution  is subject  and,  if a portion of the Offered
Securities is being sold to  underwriters,  may be subject to the condition that
the Company shall have sold to such underwriters the Offered Securities not sold
for delayed delivery.  The underwriters and such other persons will not have any
responsibility in respect of the validity or performance of such contracts.

     Unless  otherwise  specified  in the related  Prospectus  Supplement,  each
series of Offered  Securities  will be a new issue with no  established  trading
market,  other  than  Common  Shares  which  are  listed  on the New York  Stock
Exchange.  Any Common  Shares sold pursuant to a Prospectus  Supplement  will be

Item 17. Undertakings

(a)  The undersigned Registrant hereby undertakes:

     (1) To file,  during any period in which  offers or sales are being made, a
         post-effective amendment to this registration statement:

          (i)  To include any  prospectus  required  by section  10(a)(3) of the
               Securities Act of 1933;

          (ii) To reflect in the  prospectus  any facts or events  arising after
               the  effective  date of the  registration  statement (or the most
               recent post-effective  amendment thereof) which,  individually or
               in  the  aggregate,   represent  a  fundamental   change  in  the
               information   set   forth   in   this   registration   statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               of  securities  offered (if the total dollar value of  securities
               offered  would not  exceed  that  which was  registered)  and any
               deviation  from  the low or  high  end of the  estimated  maximum
               offering  range may be reflected in the form of prospectus  filed
               with the Commission  pursuant to Rule 424(b) (Section  230.424(b)
               of 17 C.F.R.)  if, in the  aggregate,  the  changes in volume and
               price  represent  no  more  than  a 20%  change  in  the  maximum
               aggregate  offering  price  set  forth  in  the  "Calculation  of
               Registration Fee" table in the effective registration  statement;
               and

          (iii)To include any material  information  with respect to the plan of
               distribution  not  previously   disclosed  in  this  registration
               statement  or any  material  change to such  information  in this
               registration statement;

     provided,  however,  that  subparagraphs  (i) and (ii) do not  apply if the
     information required to be included in a post-effective  amendment by those
     paragraphs  is contained in the periodic  reports  filed by the  Registrant
     pursuant to Section 13 or Section 15(d) of the  Securities and Exchange Act
     of 1934 that are incorporated by reference in this registration statement.

     (2) That for the purpose of determining  any liability under the Securities
         Act of 1933, each such post-effective amendment shall be deemed to be a
         new registration  statement  relating to the Securities offered herein,
         and the offering of such  Securities at that time shall be deemed to be
         the initial bona fide offering thereof.


                                      II-2

<PAGE>



     (3) To remove from registration by means of a post-effective  amendment any
         of  the  Securities   being  registered  which  remain  unsold  at  the
         termination of the offering.

(b)  The undersigned Registrant hereby further undertakes that, for the purposes
     of determining  any liability under the Securities Act of 1933, each filing
     of the  Registrant's  annual  report  pursuant to Section  13(a) or Section
     15(d) of the Securities  Exchange of 1934 that is incorporated by reference
     in this  registration  statement  shall be deemed to be a new  registration
     statement  relating to the Securities  offered herein,  and the offering of
     such  Securities  at that time shall be deemed to be the initial  bona fide
     offering thereof.

(c)  Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to trustees,  officers and controlling  persons of
     the Registrant  pursuant to the provisions  described under Item 15 of this
     registration statement, or otherwise (other than insurance), the Registrant
     has  been  advised  that in the  opinion  of the  Securities  and  Exchange
     Commission  such  indemnification  is against public policy as expressed in
     such Act and is,  therefore,  unenforceable.  In the event that a claim for
     indemnification  against  such  liabilities  (other than the payment by the
     Registrant  of  expenses  incurred  or  paid  by  a  trustee,   officer  or
     controlling  person of the  Registrant  in the  successful  defense  of any
     action,  suit or  proceeding)  is  asserted  by such  trustee,  officer  or
     controlling person in connection with the Securities being registered,  the
     Registrant  will,  unless in the opinion of its counsel the matter has been
     settled  by  controlling  precedent,  submit  to  a  court  of  appropriate
     jurisdiction  the question  whether such  indemnification  by it is against
     public  policy as  expressed  in such Act and will be governed by the final
     adjudication of such issue.

(d)  The undersigned registrant hereby undertakes that:

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

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

(e)  The undersigned registrant hereby undertakes to file an application for the
     purpose of determining  the  eligibility  of each Indenture  Trustee to act
     under  subsection  (a)  of  Section  310  of  the  Trust  Indenture  Act in
     accordance  with the rules and  regulations  prescribed  by the  Commission
     under Section 305(b)(2) of the Trust Indenture Act.

         SECTION 103. Form of Documents  Delivered to Trustee. In any case where

any such  Person may  certify  or give an  opinion as to such  matters in one or

         Any  certificate  or opinion of an officer of the Company may be based,
insofar as it  relates  to legal  matters,  upon an  Opinion  of  Counsel,  or a
certificate of or representations  by counsel,  unless such officer knows, or in

applications,  requests, consents,  certificates,  statements, opinions or other

form one instrument.

         SECTION 104. Acts of Holders. (a) Any request,  demand,  authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of the Outstanding  Securities of all series or one
or more series,  as the case may be, may be embodied in and  evidenced by one or
more instruments of substantially similar tenor signed by such Holders in person
or by agents duly  appointed in writing.  If Securities of a series are issuable
as Bearer Securities,  any request, demand,  authorization,  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


                                        8

<PAGE>


the date therein  mentioned 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: ______________________, 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

and may  have  such  letters,  numbers  or  other  marks  of  identification  or
designation and such legends or  endorsements  placed thereon as the Company may
deem  appropriate  and as are  not  inconsistent  with  the  provisions  of this
Indenture,  or as may be  required  to  comply  with any law or with any rule or
regulation  made  pursuant  thereto  or  with  any  rule  or  regulation  of any
securities  exchange  on which the  Securities  may be listed,  or to conform to
usage.

Securities shall have interest coupons attached.

         The definitive Securities and coupons shall be printed, lithographed or

         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
shall be  specified  therein  or in the  Company  Order to be  delivered  to the
Trustee pursuant to Section 303 or 304. Subject to the provisions of Section 303

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
case of a permanent  global  Security  in  registered  form,  the Holder of such
permanent  global Security in registered form or (ii) in the case of a permanent
global Security in bearer form, Euroclear or CEDEL.

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

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 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


                                       20

<PAGE>


of the  first  publication  of the  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.

                           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

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  Order,  and at  the  expense  of  the  Company,  shall  execute  proper
instruments  acknowledging  satisfaction  and discharge of this  Indenture as to
such series when

              (1)  either

                  (A) all  Securities of such series  theretofore  authenticated
         and delivered and all coupons, if any, appertaining thereto (other than
         (i) coupons appertaining to Bearer Securities  surrendered for exchange
         for  Registered  Securities  and maturing  after such  exchange,  whose
         surrender  is not  required  or has been  waived as provided in Section
         305,  (ii)  Securities  and  coupons  of such  series  which  have been
         destroyed,  lost or stolen  and which  have  been  replaced  or paid as

         called for redemption and maturing after the relevant  Redemption Date,

                  (B) all Securities of such series and, in the case of (i) or 
         (ii)  below,  any  coupons  appertaining  thereto,  not theretofore

                                    Trustee   for  the   giving   of  notice  of
                                    redemption  by the Trustee in the name,  and
                                    at the expense, of the Company, 

         and the  Company,  in the  case  of  (i),  (ii)  or  (iii)  above,  has
         irrevocably  deposited  or caused to be  deposited  with the Trustee as
         funds  in  trust  for  such  purpose  an  amount  in  the  currency  or
         currencies,  currency unit or units or composite currency or currencies
         in which the Securities of such series are payable,  sufficient to pay

         coupons not theretofore delivered to the Trustee for cancellation,  for
         principal  (and  premium,  if any)  and  interest,  and any  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

         with.

Section 606, the  obligations of the Company to any  Authenticating  Agent under

pursuant to subclause (B) of clause (1) of this Section,  the obligations of the
Trustee under  Section 402 and the last  paragraph of Section 1003 shall survive
the satisfaction and discharge of this Indenture.

         SECTION 402.  Application of Trust Funds.  Subject to the provisions of
the last  paragraph  of  Section  1003,  all money  deposited  with the  Trustee

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

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

          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

          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

          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  $___________ 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
          $___________  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

          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


                                       26

<PAGE>


Holders  of not less than a  majority  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


                                       28

<PAGE>


reasonable  compensation,  expenses,  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


                                       30

<PAGE>


lawfully 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


                                       35

<PAGE>


time an  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.

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.

                             SUPPLEMENTAL INDENTURES

         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


                                       38

<PAGE>



                  (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 the opinion of the 

                                       40

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


                                       41

<PAGE>


States or by transfer to an 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

         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

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

annual reports and quarterly  reports which the Company would have been required

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

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

certificate from the principal executive officer, principal financial officer or

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.

         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


                                       44

<PAGE>


days prior to the giving of the 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


                                       47

<PAGE>


pursuant to the terms of that 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


                                       48

<PAGE>


Holder  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


                                       49

<PAGE>


within a series  under  Section  1403,  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
of Default under Section 501(4) or 501(9) or otherwise,  as the case may be, but
except as specified  above,  the remainder of this Indenture and such Securities
and any coupons appertaining thereto shall be unaffected thereby.

         SECTION 1404.  Conditions to  Defeasance  or Covenant  Defeasance.  The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Securities of or within a series and any coupons appertaining
thereto:

                  (a) The Company shall  irrevocably have deposited or caused to
         be  deposited  with the  Trustee  (or another  trustee  satisfying  the
         requirements  of  Section  607 who  shall  agree  to  comply  with  the
         provisions of this Article Fourteen applicable to it) as trust funds in
         trust for the purpose of making the  following  payments,  specifically
         pledged as security  for, and  dedicated  solely to, the benefit of the
         Holders of such Securities and any coupons appertaining thereto, (1) an
         amount in such  currency,  currencies  or  currency  unit in which such
         Securities and any coupons  appertaining  thereto are then specified as

         payable at Stated  Maturity)  which  through the  scheduled  payment of
         principal  and  interest in respect  thereof in  accordance  with their
         terms will  provide,  not later than one day before the due date of any
         payment of principal of (and premium, if any) and interest,  if any, on
         such Securities and any coupons appertaining thereto, or (2) Government
         Obligations  applicable  to such  Securities  and coupons  appertaining
         thereto  (determined  on the  basis  of  the  currency,  currencies  or
         currency unit in which such Securities and coupons appertaining thereto
         are then  specified as payable at Stated  Maturity)  which  through the
         scheduled  payment of  principal  and  interest  in respect  thereof in
         accordance with their terms will provide, not later than one day before
         the due date of any payment of principal of (and  premium,  if any) and
         interest,  if any,  on such  Securities  and any  coupons  appertaining
         thereto, money in an amount, or (3) a combination thereof in an amount,
         sufficient,   in  the  opinion  of  a  nationally  recognized  firm  of
         independent  public  accountants  expressed in a written  certification
         thereof delivered to the Trustee, to pay and discharge, and which shall
         be applied by the  Trustee  (or other  qualifying  trustee)  to pay and
         discharge,  (i) the principal of (and premium, if any) and interest, if
         any,  on  such  Outstanding  Securities  and any  coupons  appertaining
         thereto on the Stated  Maturity of such  principal  or  installment  of
         principal or interest and (ii) any  mandatory  sinking fund payments or
         analogous  payments  applicable to such Outstanding  Securities and any
         coupons  appertaining thereto on the day on which such payments are due
         and payable in accordance  with the terms of this Indenture and of such
         Securities and any coupons appertaining thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
         a breach or violation of, or constitute a default under, this Indenture
         or any other material agreement or instrument to which the Company is a
         party or by which it is bound.

                  (c) No Event of Default or event which with notice or lapse of
         time or both  would  become an Event of  Default  with  respect to such
         Securities and any coupons appertaining thereto shall have occurred and
         be  continuing  on the date of such  deposit  or,  insofar as  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).

                  (d) In the case of an election under Section 1402, the Company
         shall have delivered to the Trustee an Opinion of Counsel  stating that
         (i) the Company has received  from, or there has been published by, the
         Internal Revenue Service a ruling,  or (ii) since the date of execution
         of this  Indenture,  there has been a change in the 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.

                  (f)  The  Company  shall  have  delivered  to the  Trustee  an
         Officers'  Certificate and an Opinion of Counsel, each stating that all
         conditions  precedent  to the  defeasance  under  Section  1402  or the
         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.

                  (g) Notwithstanding any other provisions of this 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.

         SECTION 1502. Call,  Notice and Place of Meetings.  (a) The Trustee may
at any time call a meeting  of  Holders  of  Securities  of any  series  for any
purpose  specified in Section 1501, to be held at such time and at such place in
the City of Boston, or in London as the Trustee shall determine. Notice of every
meeting of Holders of Securities  of any series,  setting forth the time and the
place of such  meeting and in general  terms the action  proposed to be taken at
such meeting,  shall be given,  in the manner  provided in Section 106, not less

request  setting forth in reasonable  detail the action  proposed to be taken at
the meeting,  and the Trustee shall not have made the first  publication  of the
notice of such meeting within 21 days after receipt of such request or shall not
thereafter proceed to cause the meeting to be held as provided herein,  then the
Company  or the  Holders  of  Securities  of such  series  in the  amount  above
specified,  as the case may be, may determine the time and the place in the City
of Boston,  or in London for such  meeting  and may call such  meeting  for such
purposes by giving notice thereof as provided in subsection (a) of this Section.

         SECTION 1503.  Persons Entitled to Vote at Meetings.  To be entitled to
vote at any meeting of Holders of  Securities  of any series,  a Person shall be

not less than a specified  percentage  in  principal  amount of the  Outstanding
Securities of a series,  the Persons entitled to vote such specified  percentage
in  principal  amount  of  the  Outstanding  Securities  of  such  series  shall

Holders  of  Securities  of such  series,  be  dissolved.  In any other case the
meeting may be adjourned for a period of not less than 10 days determined by the
chairman of the meeting prior to the adjournment of such meeting. In the absence
of a quorum at any such adjourned meeting, such adjourned meeting may be further

the  reconvening of any adjourned  meeting shall state expressly the percentage,
as provided above, of the principal amount of the Outstanding Securities of such
series which shall constitute a quorum.

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

provided,  however,  that,  except as limited by the proviso to Section 902, any
resolution  with  respect  to any  request,  demand,  authorization,  direction,
notice,  consent, waiver or other action which this Indenture expressly provides
may be made, given or taken by the Holders of a specified  percentage,  which is
less than a majority,  in principal  amount of the  Outstanding  Securities of a
series may be adopted at a meeting or an adjourned  meeting duly  reconvened and
at which a quorum is present as aforesaid by the affirmative vote of the Holders
of such specified  percentage in principal amount of the Outstanding  Securities
of that series.

         Any  resolution  passed or decision  taken at any meeting of Holders of
Securities  of any series duly held in  accordance  with this  Section  shall be
binding on all the Holders of Securities of such series and the related coupons,

waiver or other action that this Indenture expressly provides may be made, given

Outstanding  Securities  affected thereby,  or of the Holders of such series and

         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

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.

Health and Retirement Properties Trust

Newton, MA  02158

Ladies and Gentlemen:

         In connection with the registration by Health and Retirement Properties
Trust,  a  Maryland  real  estate  investment  trust (the  "Company"),  of up to
$750,000,000 in aggregate amount of (i) one or more series of debt securities of
the Company (the "Debt Securities"), (ii) one or more series of preferred shares
of beneficial interest, $.01 par value, of the Company (the "Preferred Shares"),
(iii) depositary shares representing whole or fractional  interests in Preferred
Shares   ("Depositary   Shares")  evidenced  by  depositary   receipts  therefor
("Depositary  Receipts"),  (iv) common shares of beneficial  interest,  $.01 par
value,  of the Company (the "Common  Shares"),  or (v) warrants to purchase Debt
Securities, Preferred Shares, Depositary Shares or Common Shares (the "Warrants"
and, together with the Debt Securities,  Preferred Shares and Common Shares, the
"Registered Securities"),  for offering by the Company from time to time, as set
forth in the final prospectus which forms a part of the Registration  Statement,
as defined below (the "Prospectus"), and as to be set forth in one or more final
supplements to the Prospectus (each, a "Prospectus  Supplement"),  the following
opinion is furnished to the Company to be filed with the Securities and Exchange
Commission  (the  "Commission")  as Exhibit  5.1 to the  Company's  Registration
Statement on Form S-3, File No. 333-02863,  under the Securities Act of 1933, as
amended (the "Securities Act"). As used in this opinion,  the term "Registration
Statement" means,  unless otherwise  stated,  such  Registration  Statement,  as
amended when  declared  effective by the  Commission  (including  any  necessary
post-effective amendments thereto); the term "Convertible Registered Securities"
means  Registered  Securities  which are convertible  into,  exchangeable for or
exercisable for other Registered Securities, and the term "Underlying Registered
Securities" means any Registered  Securities which are issuable upon conversion,
exchange or exercise of Convertible Registered Securities.

         In  connection  with this  opinion,  we have examined and relied upon a
copy of the  Registration  Statement,  as  originally  filed and as  modified by
Pre-Effective  Amendment No. 1 thereto  ("Amendment No. 1") to be filed with the
Commission  on or about the date hereof.  We have also  examined and relied upon
originals or copies of such records,  agreements and instruments of the Company,
certificates of public officials and of officers of the Company and such other

Health and Retirement Properties Trust

documents and records, and such matters of law, as we have deemed necessary as a
basis for the opinions  hereinafter  expressed.  In making such examination,  we
have assumed the  genuineness of all  signatures,  the legal capacity of natural
persons,  the authenticity of all documents submitted to us as originals and the
conformity to the originals of all  documents  submitted to us as copies,  which
facts we have not independently verified.

         We have necessarily  assumed in connection with the opinions  expressed
below that the terms and conditions of the Registered Securities and any related
indentures,  agreements and  instruments,  except to the extent described in the
Registration Statement and the form of preliminary prospectus contained therein,
as originally filed and as amended through Pre- Effective Amendment No. 1 to the
Registration Statement, will be, and that any related proceedings of the Company
conducted  after the date hereof will be conducted,  (i) in accordance  with all
applicable laws and the Company's Amended and Restated  Declaration of Trust (as
currently  in effect,  the  "Declaration  of Trust") and By-laws and (ii) not in
conflict with any  contractual  or other  restrictions  which are binding on the
Company,  and that,  without limiting the generality of the foregoing,  that any
agreements or instruments which are hereafter required to be filed as an exhibit
to the Registration  Statement will be properly filed by an amendment thereto or
by the filing of a Form 8-K by the Company under the Securities  Exchange Act of
1934, as amended,  and properly  incorporated  by reference in the  Registration
Statement,  as permitted by the Securities Act and the rules and  regulations of
the Commission  thereunder.  We have also necessarily assumed in connection with
such  opinions  with  respect to any Common  Shares or  Preferred  Shares or any
Convertible  Registered Securities as to which Common Shares or Preferred Shares
are the related Underlying Securities that, at the time of the issuance thereof,
the Company will have a sufficient  number of shares of authorized Common Shares
or Preferred  Shares,  as the case may be, under the  Declaration of Trust which
will be unissued and not otherwise reserved for issuance.

         To the extent that the  obligations  of the Company under the Indenture
or any Warrant Agreement or Depositary  Agreement (each as defined below) may be
dependent  upon such matters,  we have assumed for purposes of this opinion that
the Trustee and each Warrant Agent and  Depositary  (each as defined  below) are
duly  organized,  validly  existing and in good standing under the laws of their
respective  jurisdictions of  organization,  and are duly qualified to engage in
the activities contemplated by, and have the requisite  organizational and legal
power and authority to perform their respective obligations under, the Indenture
and each Warrant  Agreement and Depositary  Agreement to which they are parties,
that the Trustee and each Warrant Agent and  Depositary  will be in  compliance,
generally  with respect to acting as a trustee or agent under the  Indenture and
each applicable Warrant Agreement and Depositary Agreement,  with all applicable
laws and  regulations,  and that the  Indenture  and any Warrant  Agreement  and
Depositary  Agreement  will be the valid and  binding  agreements  of each party
thereto  (other  than,  in the case of an indenture in the form filed as Exhibit
4.1 to the Registration  Statement when appropriately  completed,  the Company),
enforceable against such parties in accordance with their respective terms.

         We express no opinion herein as to the laws of any  jurisdiction  other
than the Commonwealth of Massachusetts and the federal law of the United States,
and we express no opinion as to state  securities  or blue sky laws.  Insofar as
this opinion  involves  matters of Maryland law we have,  with your  permission,
relied  solely  on the  opinion  of Piper & Marbury  L.L.P.,  a copy of which is
attached  hereto,  and our opinion is subject to the exceptions,  qualifications
and limitations therein expressed.

         Our  opinions  set forth below with  respect to the validity or binding
effect of any  security or  obligation  are subject to (i)  limitations  arising
under applicable bankruptcy, insolvency, reorganization,  fraudulent conveyance,
moratorium or other  similar laws  affecting  the  enforcement  generally of the
rights and  remedies of  creditors  and secured  parties or the  obligations  of
debtors,  (ii) general principles of equity (regardless of whether considered in
a proceeding at law or in equity), including, without limitation, the discretion
of any court of  competent  jurisdiction  in granting  specific  performance  or
injunctive or other equitable  relief,  and (iii) an implied duty on the part of
the  party  seeking  to  enforce  rights or  remedies  to take  action  and make
determinations on a reasonable basis and in good faith to the extent required by
applicable law.

         Based on and subject to the  foregoing,  we are of the opinion that, as
of the date hereof:

                  1. Each series of Debt  Securities  will be validly issued and
         binding obligations of the Company when (i) the Registration  Statement
         shall have become  effective under the Securities Act and the indenture
         filed as  Exhibit  4.1 to the  Registration  Statement,  including  any
         necessary supplemental indenture, or any other indenture, including any
         necessary  supplemental  indenture thereto,  filed as an exhibit to the
         Registration  Statement,  as the case may be (the applicable indenture,
         as so  filed  and  supplemented,  the  "Indenture"),  shall  have  been
         qualified  under the Trust  Indenture Act of 1939, as amended,  and the

         such Debt Securities as contemplated by the Registration Statement, the
         Prospectus, the applicable Prospectus Supplement and the Indenture, and
         (iv) such series of Debt  Securities  shall have been (A) duly executed

         delivered  to the  purchasers  thereof  against  payment  of the agreed
         consideration therefor, as provided in the Registration Statement,  the
         Prospectus, the applicable Prospectus Supplement, the Indenture and the
         Final  Debt  Resolutions.   If  such  Debt  Securities  are  Underlying
         Registered  Securities,  the  opinion  set forth in this  paragraph  is
         subject  to the  further  condition  that  the  Convertible  Registered
         Securities  relating  to  such  Debt  Securities,  at the  time  of the
         issuance thereof and of the conversion,  exchange or exercise  thereof,
         are validly issued, fully paid and non-assessable by the Company or are

         authorized  committee thereof shall have duly adopted final resolutions
         (the "Final Preferred Shares Resolutions") authorizing the issuance and

         restrictions, limitations as to dividends, qualifications and terms and
         conditions of redemption,  consistent with the Final  Preferred  Shares
         Resolutions,  shall have been duly executed and filed with and accepted

         consideration  therefor  (and in any event an amount at least  equal to
         the par value thereof), as provided in the Registration Statement,  the
         Prospectus,   the  applicable   Prospectus  Supplement  and  the  Final
         Preferred Shares  Resolutions.  If such Preferred Shares are Underlying

         Securities  relating  to  such  Preferred  Shares,  at the  time of the
         issuance thereof and of the conversion,  exchange or exercise  thereof,
         are validly issued, fully paid and non-assessable by the Company or are

         validly  issued  and will  entitle  the  holders  thereof to the rights
         specified therein and in the applicable Depositary Agreement,  when (i)

         related  Preferred Shares are met, (ii) the Company's Board of Trustees
         or  a  duly  authorized  committee  thereof  shall  have  duly  adopted

         under the Depositary and (v) the applicable  Depositary  Receipts shall

         Depositary  Agreement and the Final Depositary  Shares  Resolutions and

         provided in the Registration Statement, the Prospectus,  the applicable
         Prospectus Supplement and the Final Common Shares Resolutions.  If such

         agreements,  including a form of warrant  set forth  therein or related
         thereto  (each,  a  "Warrant  Agreement"),  establishing  the terms and

         executed and  delivered by the Company and the Warrant  Agent,  and (v)
         such  Warrants  shall  have  been  duly  executed  by the  Company  and
         authenticated  by the  Warrant  Agent  as  provided  in the  applicable

         at the time of the issuance thereof and of the conversion,  exchange or

                  Re:      Registration Statement on Form S-3 of
                           Health and Retirement Properties Trust

Ladies and Gentlemen:

         We have acted as counsel to Health and Retirement  Properties  Trust, a
Maryland real estate  investment trust (the  "Company"),  in connection with the
preparation  of  a  Registration   Statement  on  Form  S-3  (the  "Registration
Statement") filed with the Securities and Exchange Commission (the "Commission")
under the  Securities  Act of 1933,  as amended  (the  "Securities  Act"),  with
respect to the  contemplated  issuance by the Company from time to time of up to
$750,000,000  aggregate  public  offering price of (i) unsecured debt securities
("Debt  Securities");  (ii)  preferred  shares  of  beneficial  interest  of the
Company, par value $.01 per share ("Preferred Shares");  (iii) depositary shares
representing  whole or fractional  shares of the Preferred  Shares  ("Depositary
Shares")  evidenced by Depositary  Receipts therefor  ("Receipts");  (iv) common
shares of  beneficial  interest of the  Company,  par value $.01 share  ("Common
Shares");  and  (v)  warrants  of the  Company  to  purchase  any  of the  above
securities  ("Warrants"  and  together  with  Debt  Securities,  Common  Shares,
Preferred Shares and Depositary Shares, "Securities").

         We have examined originals or copies, certified or otherwise identified
to our  satisfaction,  of such  documents,  corporate  records,  certificates of
public  officials  and other  instruments  as we have deemed  necessary  for the
purpose of rendering this opinion.  In addition,  this opinion is based upon the
assumption  that the  Registration  Statement  and any  required  post-effective
amendments  thereto  have become  effective  under the  Securities  Act. In such
examination, we have assumed, without independent investigation, the genuineness
of all  signatures,  the legal capacity of all individuals who have executed any
of the aforesaid documents, the authenticity of all documents submitted to us as
originals and the conformity with originals of all documents  submitted to us as
copies.

         On the basis of the foregoing we are of the opinion that:

         1. The  Company  has been duly  formed and is validly  existing in good
standing  as a real  estate  investment  trust  under  the laws of the  State of
Maryland.

         2. When (i) the terms of the Debt  Securities and of their issuance and
sale have been duly established in conformity with the Indenture relating to the
Debt  Securities so as not to violate any  applicable law or result in a default
under or breach of any agreement or  instrument  binding upon the Company and so
as to  comply  with any  requirement  or  restriction  imposed  by any  court or
governmental or regulatory body having  jurisdiction over the Company;  and (ii)
the Debt Securities have been duly executed and authenticated in accordance with
the  Indenture  relating  to the Debt  Securities,  and duly  issued and sold as
contemplated  by  the  Registration  Statement  and  any  prospectus  supplement
relating thereto, the Debt Securities (including any Debt Securities duly issued
upon exercise,  conversion or exchange of any other Securities  exercisable for,
convertible  into or exchangeable for Debt Securities) will constitute valid and
legally binding  obligations of the Company enforceable in accordance with their
terms,  subject  to  (a)  bankruptcy,  insolvency,  reorganization,   fraudulent
transfer,  moratorium and other similar laws now or hereafter in effect relating
to or affecting creditors rights generally, and (b) general principles of equity
(regardless of whether considered in a proceeding at law or in equity).

         3.  When (i) the  terms of the  Preferred  Shares  have  been  duly and
properly  authorized for issuance and Articles  Supplementary to the Declaration
of Trust of the Company  classifying the Preferred  Shares and setting forth the
terms  thereof have been filed;  and (ii) such  Preferred  Shares have been duly
issued, sold and delivered as contemplated in the Registration Statement and any
prospectus  supplement  relating  thereto,  such Preferred Shares (including any
Preferred Shares duly issued upon exercise,  conversion or exchange of any other
Securities  exercisable  for,  convertible  into or  exchangeable  for Preferred
Shares) will be validly issued, fully paid and nonassessable.

         4. When (i) the Common  Shares have been duly and  properly  authorized
for  issuance;  and (ii) the  Common  Shares  have  been duly  issued,  sold and
delivered as  contemplated  in the  Registration  Statement  and any  prospectus
supplement relating thereto, the Common Shares (including any Common Shares duly
issued  upon the  exercise,  conversion  or  exchange  of any  other  Securities
exercisable  for,  convertible  into or exchangeable  for Common Shares) will be
validly issued, fully paid and nonassessable.

         5. When (i) the Deposit  Agreement  relating to the  Depositary  Shares
(the "Deposit  Agreement") has been duly executed and delivered;  (ii) the terms
of the  Depositary  Shares  and of  their  issuance  and  sale  have  been  duly
established in conformity with the Deposit Agreement relating to such Depositary
Shares so as not to violate any  applicable  law or result in a default under or

comply with any requirement or restriction  imposed by any court or governmental
or regulatory body having jurisdiction over the Company;  (iii) the terms of the

(including  any  Depositary  Shares  duly issued upon  exercise,  conversion  or
exchange  of  any  other  Securities   exercisable  for,   convertible  into  or
exchangeable   for  Depositary   Shares)  will  be  validly  issued,   paid  and
nonassessable,  and such  Receipts  will be validly  issued and will entitle the
holders thereof to the rights specified therein and in the Deposit Agreement.

         6.  When  (i) the  Warrant  Agreement  relating  to the  Warrants  (the
"Warrant Agreement") has been duly executed and delivered; (ii) the terms of the
Warrants and of their issuance and sale have been duly established in conformity
with the Warrant  Agreement  relating to such  Warrants so as not to violate any
applicable  law or  result in a default  under or  breach  of any  agreement  or
instrument  binding upon the Company and so as to comply with any requirement or
restriction  imposed by any court or  governmental  or  regulatory  body  having
jurisdiction  over the Company;  and (iii) the Warrants  have been duly executed
and  countersigned  in accordance  with the Warrant  Agreement  relating to such
Warrants,  and issued and sold in the form and in the manner contemplated in the
Registration  Statement and any prospectus  supplement  relating  thereto,  such
Warrants  (including  any  Warrants  duly issued upon  exercise,  conversion  or
exchange  of  any  other  Securities   exercisable  for,   convertible  into  or
exchangeable  for such  Warrants)  will  constitute  valid and  legally  binding
obligations of the Company  enforceable in accordance with their terms,  subject
to (a) bankruptcy, insolvency,  reorganization,  fraudulent transfer, moratorium
and other  similar  laws now or  hereafter  in effect  relating to or  affecting
creditors' rights generally, and (b) general principles of equity (regardless of
whether considered in a proceeding at law or in equity).

         The  foregoing  opinions  are  limited  to the  laws  of the  State  of
Maryland.

         We hereby  consent  to the use of this  opinion  as an  exhibit  to the
Registration Statement and to the reference to our name under the heading "Legal
Matters."
